You probably +want to get the most up to date version of this from ftp.sendmail.org +in /pub/sendmail/KNOWNBUGS. For descriptions of bugs that have been +fixed, see the file RELEASE_NOTES (in the root directory of the sendmail +distribution). + +This list is not guaranteed to be complete. + + +* Null bytes are not handled properly in headers. + + Sendmail should handle full binary data. As it stands, it handles + all values in the body, but only 0x01-0x80 and 0xA0-0xFF in + the header. Notably missing is 0x00, which would require a major + restructuring of the code -- for example, almost no C library support + could be used to handle strings. + +* Duplicate error messages. + + Sometimes identical, duplicate error messages can be generated. As + near as I can tell, this is rare and relatively innocuous. + +* $c (hop count) macro improperly set. + + The $c macro is supposed to contain the current hop count, for use + when calling a mailer. This macro is initialized too early, and + is always zero (or the value of the -c command line flag, if any). + This macro will probably be removed entirely in a future release; + I don't believe there are any mailers left that require it. + +* If you EXPN a list or user that has a program mailer, the output of + EXPN will include ``@local.host.name''. You can't actually mail to + this address. It's not clear what the right behavior is in this + circumstance. + +* \231 considered harmful. + + Header addresses that have the \231 character (and possibly others + in the range \201 - \237) behave in odd and usually unexpected ways. + +* accept() problem on SVR4. + + Apparently, the sendmail daemon loop (doing accept()s on the network) + can get into a weird state on SVR4; it starts logging ``SYSERR: + getrequests: accept: Protocol Error''. The workaround is to kill + and restart the sendmail daemon. We don't have an SVR4 system at + Berkeley that carries more than token mail load, so I can't validate + this. It is likely to be a glitch in the sockets emulation, since + "Protocol Error" is not possible error code with Berkeley TCP/IP. + + I've also had someone report the message ``sendmail: accept: + SIOCGPGRP failed errno 22'' on an SVR4 system. This message is + not in the sendmail source code, so I assume it is also a bug + in the sockets emulation. (Errno 22 is EINVAL "Invalid Argument" + on all the systems I have available, including Solaris 2.x.) + Apparently, this problem is due to linking -lc before -lsocket; + if you are having this problem, check your Makefile. + +* accept() problem on Linux. + + Apparently, the accept() in sendmail daemon loop can return ETIMEDOUT + and cause sendmail to sleep for 5 seconds during which time no new + connections will be accepted. An error is reported to syslog: + + Jun 9 17:14:12 hostname sendmail[207]: NOQUEUE: SYSERR(root): + getrequests: accept: Connection timed out + + "Connection timed out" is not documented as a valid return from + accept(2) and this was believed to be a bug in the Linux kernel. + Later information from the Linux kernel group states that Linux + 2.0 kernels follow RFC1122 while sendmail follows the original BSD + (now POSIX 1003.1g draft) specification. The 2.1.X and later kernels + will follow the POSIX draft. + +* Excessive mailing list nesting can run out of file descriptors. + + If you have a mailing list that includes lots of other mailing + lists, each of which has a separate owner, you can run out of + file descriptors. Each mailing list with a separate owner uses + one open file descriptor (prior to 8.6.6 it was three open + file descriptors per list). This is particularly egregious if + you have your connection cache set to be large. + +* Connection caching breaks if you pass the port number as an argument. + + If you have a definition such as: + + Mport, P=[IPC], F=kmDFMuX, S=11/31, R=21, + M=2100000, T=DNS/RFC822/SMTP, + A=IPC [127.0.0.1] $h + + (i.e., where $h is the port number instead of the host name) the + connection caching code will break because it won't notice that + two messages addressed to different ports should use different + connections. + +* ESMTP SIZE underestimates the size of a message + + Sendmail makes no allowance for headers that it adds, nor does it + account for the SMTP on-the-wire \r\n expansion. It probably doesn't + allow for 8->7 bit MIME conversions either. + +* Paths to programs being executed and the mode of program files are + not checked. Essentially, the RunProgramInUnsafeDirPath and + RunWritableProgram bits in the DontBlameSendmail option are always + set. This is not a problem if your system is well managed (that is, + if binaries and system directories are mode 755 instead of something + foolish like 777). + +* 8-bit data in GECOS field + + If the GECOS (personal name) information in the passwd file contains + 8-bit characters, those characters can be included in the message + header, which can cause problems when sending SMTP to hosts that + only accept 7-bit characters. + +* 8->7 bit MIME conversion + + When sendmail is doing 8->7 bit MIME conversions, and the message + contains certain MIME body types that cannot be converted to 7-bit, + sendmail will strip the message to 7-bit. + +* 7->8 bit MIME conversion + + If a message that is encoded as 7-bit MIME is converted to 8-bit and + that message when decoded is illegal (e.g., because of long lines or + illegal characters), sendmail can produce an illegal message. + +* MIME encoded full name phrases in the From: header + + If a full name phrase includes characters from MustQuoteChars, sendmail + will quote the entire full name phrase. If MustQuoteChars includes + characters which are not special characters according to STD 11 (RFC + 822), this quotation can interfere with MIME encoded full name phrases. + By default, sendmail includes the single quote character (') in + MustQuoteChars even though it is not listed as a special character in + STD 11. + + +(Version 8.32, last updated 6/30/98) diff --git a/contrib/sendmail/LICENSE b/contrib/sendmail/LICENSE new file mode 100644 index 000000000000..bb1c3a79c7f0 --- /dev/null +++ b/contrib/sendmail/LICENSE @@ -0,0 +1,89 @@ + SENDMAIL LICENSE + +The following license terms and conditions apply, unless a different +license is obtained from Sendmail, Inc., 1401 Park Avenue, Emeryville, CA +94608, or by electronic mail at license@sendmail.com. + +License Terms: + +Use, Modification and Redistribution (including distribution of any +modified or derived work) in source and binary forms is permitted only if +each of the following conditions is met: + +1.

For sendmail to run +without complaining, you MUST execute the following command: + + chmod go-w / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue + chown root / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue + +You will probably have to tweak this for your environment (for example, +some systems put the spool directory into /usr/spool instead of +/var/spool and use /etc/mail for aliases file instead of /etc). If you +set the RunAsUser option in your sendmail.cf, the /var/spool/mqueue +directory will have to be owned by the RunAsUser user. As a general rule, +after you have compiled sendmail, run the command + + sendmail -v -bi + +to initialize the alias database. If it gives messages such as + + WARNING: writable directory /etc + WARNING: writable directory /usr/spool/mqueue + +then the directories listed have inappropriate write permissions and +should be secured to avoid various possible security attacks. + +Beginning with sendmail 8.9, these checks have become more strict to +prevent users from being able to access files they would normally not +be able to read. In particular, .forward and :include: files in unsafe +directory paths (directory paths which are group or world writable) will +no longer be allowed. This would mean that if user joe's home directory +was writable by group staff, sendmail would not use his .forward file. +This behavior can be altered, at the expense of system security, by +setting the DontBlameSendmail option. For example, to allow .forward +files in group writable directories: + + O DontBlameSendmail=forwardfileingroupwritabledirpath + +Or to allow them in both group and world writable directories: + + O DontBlameSendmail=forwardfileinunsafedirpath + +Items from these unsafe .forward and :include: files will be marked +as unsafe addresses -- the items can not be deliveries to files or +programs. This behavior can also be altered via DontBlameSendmail: + + O DontBlameSendmail=forwardfileinunsafedirpath, + forwardfileinunsafedirpathsafe + +The first flag allows the .forward file to be read, the second allows +the items in the file to be marked as safe for file and program +delivery. + +Other files affected by this strengthened security include class +files (i.e. Fw /etc/sendmail.cw), persistent host status files, and +the files specified by the ErrorHeader and HelpFile options. Similar +DontBlameSendmail flags are available for the class, ErrorHeader, and +HelpFile files. + +If you have an unsafe configuration of .forward and :include: +files, you can make it safe by finding all such files, and doing +a "chmod go-w $FILE" on each. Also, do a "chmod go-w $DIR" for +each directory in the file's path. + + ++--------------+ +| MANUAL PAGES | ++--------------+ + +The sendmail manual pages use contemporary Berkeley troff macros. If +your system does not process these manual pages, you can pick up the +new macros in a BSD Net/2 FTP site (e.g. on FTP.UU.NET, the files +/systems/unix/bsd-sources/share/tmac/*). + +The strip.sed file is only used in installation. + +After installation, edit tmac.doc and tmac.andoc to reflect the +installation path of the tmac files. Those files contain pointers to +/usr/share/tmac/, and those pointers are not changed by the `make +install` process. There's also a bug in those files -- make the +following patch: + +*** tmac.an~ Tue Jul 12 14:29:09 1994 +--- tmac.an Fri Jul 15 13:17:54 1994 +*************** +*** 50,55 **** + .de TH + .rn TH xX + .so /usr/share/lib/tmac/tmac.an.old +! .TH \\$1 \\$2 \\$3 \\$4 \\$5 \\$6 \\$7 \\$8 + .rm xX + .. +--- 50,55 ---- + .de TH + .rn TH xX + .so /usr/share/lib/tmac/tmac.an.old +! .TH "\\$1" "\\$2" "\\$3" "\\$4" "\\$5" "\\$6" "\\$7" "\\$8" + .rm xX + .. + +Rename the existing tmac.an to be tmac.an.old, and rename tmac.andoc +to be tmac.an. + +tmac.an will choose between tmac.an.old, your old macros, or tmac.doc, +which are the new macros, so that both the new man pages and the +existing man pages will be translated properly. + +I'm also told that the groff distribution from MIT has a tmac.doc +macro set that is compatible with these macros. + + ++-----------------------+ +| RELATED DOCUMENTATION | ++-----------------------+ + +There are other files you should read.

Be warned: if + you are running this off on SunOS or some other system with an + old version of -me, you need to add the following macro to the + macros: + + .de sm + \s-1\\$1\\s0\\$2 + .. + + This sets a word in a smaller pointsize. + + ++--------------+ +| RELATED RFCS | ++--------------+ + +There are several related RFCs that you may wish to read -- they are +available via anonymous FTP to several sites, including: + + ftp://nic.ddn.mil/rfc/ + ftp://nis.nsf.net/documents/rfc/ + ftp://nisc.jvnc.net/rfc/ + ftp://venera.isi.edu/in-notes/ + ftp://wuarchive.wustl.edu/doc/rfc/ + +For a list of the primary repositories see: + + http://www.isi.edu/in-notes/rfc-retrieval.txt + +They are also online at: + + http://www.ietf.org/ + +They can also be retrieved via electronic mail by sending +email to one of: + + mail-server@nisc.sri.com + Put "send rfcNNN" in message body + nis-info@nis.nsf.net + Put "send RFCnnn.TXT-1" in message body + sendrfc@jvnc.net + Put "RFCnnn" as Subject: line + +For further instructions see: + + http://www.isi.edu/in-notes/rfc-editor/rfc-info + +Important RFCs for electronic mail are: + + RFC821 SMTP protocol + RFC822 Mail header format + RFC974 MX routing + RFC976 UUCP mail format + RFC1123 Host requirements (modifies 821, 822, and 974) + RFC1413 Identification server + RFC1869 SMTP Service Extensions (ESMTP spec) + RFC1652 SMTP Service Extension for 8bit-MIMEtransport + RFC1870 SMTP Service Extension for Message Size Declaration + RFC2045 Multipurpose Internet Mail Extensions (MIME) Part One: + Format of Internet Message Bodies + RFC1344 Implications of MIME for Internet Mail Gateways + RFC1428 Transition of Internet Mail from Just-Send-8 to + 8-bit SMTP/MIME + RFC1891 SMTP Service Extension for Delivery Status Notifications + RFC1892 Multipart/Report Content Type for the Reporting of + Mail System Administrative Messages + RFC1893 Enhanced Mail System Status Codes + RFC1894 An Extensible Message Format for Delivery Status + Notifications + RFC1985 SMTP Service Extension for Remote Message Queue Starting + +Other standards that may be of interest (but which are less directly +relevant to sendmail) are: + + RFC987 Mapping between RFC822 and X.400 + RFC1049 Content-Type header field (extension to RFC822) + +Warning to AIX users: this version of sendmail does not implement +MB, MR, or MG DNS resource records, as defined (as experiments) in +RFC1035. + + ++-------------------+ +| DATABASE ROUTINES | ++-------------------+ + +IF YOU WANT TO RUN THE NEW BERKELEY DB SOFTWARE: **** DO NOT **** +use the version that was on the Net2 tape -- it has a number of +nefarious bugs that were bad enough when I got them; you shouldn't have +to go through the same thing. Instead, get a new version via the web at +http://www.sleepycat.com/. This software is highly recommended; it gets +rid of several stupid limits, it's much faster, and the interface is +nicer to animals and plants. If the Berkeley DB include files +are installed in a location other than those which your compiler searches, +you will need to provide that directory when building: + + Build -I/path/to/include/directory + +If you are using Berkeley DB versions 1.85 or 1.86, you are *strongly* +urged to upgrade to DB version 2, available from http://www.sleepycat.com/. +Berkeley DB versions 1.85 and 1.86 are known to be broken in various nasty +ways (see http://www.sleepycat.com/db.185.html), and can cause sendmail +to dump core. In addition, the newest versions of gcc and the Solaris +compilers perform optimizations in those versions that may cause fairly +random core dumps. + +If you have no choice but to use Berkeley DB 1.85 or 1.86, and you are +using both Berkeley DB and files in the UNIX ndbm format, remove ndbm.h +and ndbm.o from the DB library after building it. You should also apply +all of the patches for DB 1.85 and 1.86 found at the Sleepycat web site +(see http://www.sleepycat.com/db.185.html), as they fix some of the known +problems. + +If you are using a version of Berkeley DB 2 previous to 2.3.15, and you +are using both Berkeley DB and files in the UNIX ndbm format, remove dbm.o +from the DB library after building it. No other changes are necessary. + +If you are using Berkeley DB version 2.3.15 or greater, no changes are +necessary. + +The underlying database file formats changed between Berkeley DB versions +1.85 and 1.86, and again between DB 1.86 and version 2.0. If you are +upgrading from one of those versions, you must recreate your database +file(s). Do this by rebuilding all maps with makemap and rebuilding the +alias file with newaliases. + + ++--------------------+ +| HOST NAME SERVICES | ++--------------------+ + +If you are using NIS or /etc/hosts, it is critical that you +list the long (fully qualified) name somewhere (preferably first) in +the /etc/hosts file used to build the NIS database. For example, the +line should read + + 128.32.149.68 mastodon.CS.Berkeley.EDU mastodon + +**** NOT **** + + 128.32.149.68 mastodon + +If you do not include the long name, sendmail will complain loudly +about ``unable to qualify my own domain name (mastodon) -- using +short name'' and conclude that your canonical name is the short +version and use that in messages. The name "mastodon" doesn't mean +much outside of Berkeley, and so this creates incorrect and unreplyable +messages. + + ++-------------+ +| USE WITH MH | ++-------------+ + +This version of sendmail notices and reports certain kinds of SMTP +protocol violations that were ignored by older versions. If you +are running MH you may wish to install the patch in contrib/mh.patch +that will prevent these warning reports. This patch also works +with the old version of sendmail, so it's safe to go ahead and +install it. + + ++----------------+ +| USE WITH IDENT | ++----------------+ + +Sendmail 8 supports the IDENT protocol, as defined by RFC 1413. +No ident server is included with this distribution. I have found +copies available on: + + ftp.lysator.liu.se /pub/ident/servers + romulus.ucs.uoknor.edu /networking/ident/servers + ftp.cyf-kr.edu.pl /agh/uciagh/network/ident + +If you want to run an IDENT server, I suggest getting a copy from +one of those sites. Versions are available for several different +systems, including Apollo, BSD, NeXT, AIX, TOPS20, and VMS. + + ++---------------------+ +| DIRECTORY STRUCTURE | ++---------------------+ + +The structure of this directory tree is: + +cf Source for sendmail configuration files. These are + different than what you've seen before. They are a + fairly dramatic rewrite, requiring the new sendmail + (since they use new features). +contrib Some contributed tools to help with sendmail. THESE + ARE NOT SUPPORTED by sendmail -- contact the original + authors if you have problems. (This directory is not + on the 4.4BSD tape.) +doc Documentation. If you are getting source, read + op.me -- it's long, but worth it. +mail.local The source for the local delivery agent used for 4.4BSD. + THIS IS NOT PART OF SENDMAIL! and may not compile + everywhere, since it depends on some 4.4-isms. Warning: + it does mailbox locking differently than other systems. +mailstats Statistics printing program. It has the pathname of + sendmail.st compiled in, so if you've changed that, + beware. +makemap A program that creates the keyed maps used by the $( ... $) + construct in sendmail. It is primitive but effective. + It takes a very simple input format, so you will probably + expect to preprocess must human-convenient formats + using sed scripts before this program will like them. + But it should be functionally complete. +praliases A program to print the DBM or NEWDB version of the + aliases file. +rmail Source for rmail(8). This is used as a delivery + agent for for UUCP, and could presumably be used by + other non-socket oriented mailers. Older versions of + rmail are probably deficient. RMAIL IS NOT PART OF + SENDMAIL!!! The 4.4BSD source is included for you to + look at or try to port to your system. I know it doesn't + compile on {SunOS, HP-UX, OSF/1, other} (pick one). +smrsh The "sendmail restricted shell", which can be used as + a replacement for /bin/sh in the prog mailer to provide + increased security control. NOT PART OF SENDMAIL! +src Source for the sendmail program itself. +test Some test scripts (currently only for compilation aids). diff --git a/contrib/sendmail/RELEASE_NOTES b/contrib/sendmail/RELEASE_NOTES new file mode 100644 index 000000000000..2b3475ffbcc6 --- /dev/null +++ b/contrib/sendmail/RELEASE_NOTES @@ -0,0 +1,6323 @@ + SENDMAIL RELEASE NOTES + @(#)RELEASE_NOTES 8.9.1.1 (Berkeley) 7/2/98 + + +This listing shows the version of the sendmail binary, the version +of the sendmail configuration files, the date of release, and a +summary of the changes in that release. + +8.9.1/8.9.1 98/07/02 + If both an OS specific site configuration file and a generic + site.config.m4 file existed, only the latter was used + instead of both. Problem noted by Geir Johannessen of + the Norwegian University of Science and Technology. + Fix segmentation fault while converting 8 bit to 7 bit MIME + multipart messages by trying to write to an unopened + file descriptor. Fix from Kari Hurtta of the Finnish + Meteorological Institute. + Do not assume Message: and Text: headers indicate the end of + the header area when parsing MIME headers. Problem noted + by Kari Hurtta of the Finnish Meteorological Institute. + Setting the confMAN#SRC Build variable would only effect the + installation commands. The man pages would still be + built with .0 extensions. Problem noted by Bryan + Costales of InfoBeat, Inc. + Installation of manual pages didn't honor the DESTDIR environment + variable. Problem noted by Bryan Costales of InfoBeat, Inc. + If the check_relay ruleset resolved to the discard mailer, messages + were still delivered. Problem noted by Mirek Luc of NASK. + Mail delivery to files would fail with an Operating System Error + if sendmail was not running as root, i.e. RunAsUser was set. + Problem noted by Leonard N. Zubkoff of Dandelion Digital. + Prevent MinQueueAge from interfering from queued items created + in the future, i.e. if the system clock was set ahead + and then back. Problem noted by Michael Miller of the + University of Natal, Pietermaritzburg. + Do not advertise ETRN support in ESTMP EHLO reply if noetrn is + set in the PrivacyFlags option. Fix from Ted Rule of + Flextech TV. + Log invalid persistent host status file lines instead of + bouncing the message. Problem noted by David Lindes of + DaveLtd Enterprises. + Move creation of empty sendmail.st file from installation to + compilation. Installation may be done from a read-only + mount. Fix from Bryan Costales of InfoBeat, Inc. and Ric + Anderson of the Oasis Research Center, Inc. + Enforce the maximum number of User Database entries limit. Problem + noted by Gary Buchanan of Credence Systems Inc. + Allow dead.letter files in root's home directory. Problem noted + by Anna Ullman of Sun Microsystems. + Program deliveries in forward files could be marked unsafe if + any directory listed in the ForwardPath option did not + exist. Problem noted by Jorg Bielak of Coastal Web Online. + Do not trust the length of the address structure returned by + gethostbyname(). Problem noted by Chris Evans of Oxford + University. + If the SIZE= MAIL From: ESMTP parameter is too large, use the + 5.3.4 DSN status code instead of 5.2.2. Similarly, for + non-local deliveries, if the message is larger than the + mailer maximum message size, use 5.3.4 instead of 5.2.3. + Suggested by Antony Bowesman of + Fujitsu/TeaWARE Mail/MIME System. + Portability: + Fix the check for an IP address reverse lookup for + use in $&{client_name} on 64 bit platforms. + From Gilles Gallot of Institut for Development + and Resources in Intensive Scientific computing. + BSD-OS uses .0 for man page extensions. From Jeff Polk + of BSDI. + DomainOS detection for Build. Also, version 10.4 and later + ship a unistd.h. Fixes from Takanobu Ishimura of + PICT Inc. + NeXT 4.x uses /usr/lib/man/cat for its man pages. From + J. P. McCann of E I A. + SCO 4.X and 5.X include NDBM support. From Vlado Potisk + of TEMPEST, Ltd. + CONFIG: Do not pass spoofed PTR results through resolver for + qualification. Problem noted by Michiel Boland of + Digital Valley Internet Professionals; fix from + Kari Hurtta of the Finnish Meteorological Institute. + CONFIG: Do not try to resolve non-DNS hostnames such as UUCP, + BITNET, and DECNET addresses for resolvable senders. + Problem noted by Alexander Litvin of Lucky Net Ltd. + CONFIG: Work around Sun's broken configuration which sends bounce + messages as coming from @@hostname instead of <>. LMTP + would not accept @@hostname. + OP.ME: Corrections to complex sendmail startup script from Rick + Troxel of the National Institutes of Health. + RMAIL: Do not install rmail by default, require 'make force-install' + as this rmail isn't the same as others. Suggested by + Kari Hurtta of the Finnish Meteorological Institute. + +8.9.0/8.9.0 98/05/19 + SECURITY: To prevent users from reading files not normally + readable, sendmail will no longer open forward, :include:, + class, ErrorHeader, or HelpFile files located in unsafe + (i.e. group or world writable) directory paths. Sites + which need the ability to override security can use the + DontBlameSendmail option. See the README file for more + information. + SECURITY: Problems can occur on poorly managed systems, specifically, + if maps or alias files are in world writable directories. + This fixes the change added to 8.8.6 to prevent links in these + world writable directories. + SECURITY: Make sure ServiceSwitchFile option file is not a link if + it is in a world writable directory. + SECURITY: Never pass a tty to a mailer -- if a mailer can get at the + tty it may be able to push bytes back to the senders input. + Unfortunately this breaks -v mode. Problem noted by + Wietse Venema of the Global Security Analysis Lab at + IBM T.J. Watson Research. + SECURITY: Empty group list if DontInitGroups is set to true to + prevent program deliveries from picking up extra group + privileges. Problem reported by Wolfgang Ley of DFN-CERT. + SECURITY: The default value for DefaultUser is now set to the uid and + gid of the first existing user mailnull, sendmail, or daemon + that has a non-zero uid. If none of these exist, sendmail + reverts back to the old behavior of using uid 1 and gid 1. + This is a security problem for Linux which has chosen that + uid and gid for user bin instead of daemon. If DefaultUser + is set in the configuration file, that value overrides this + default. + SECURITY: Since 8.8.7, the check for non-setuid binaries + interfered with setting an alternate group id for the + RunAsUser option. Problem noted by Randall Winchester of + the University of Maryland. + Add support for Berkeley DB 2.X. Based on patch from John Kennedy + of Cal State University, Chico. + Remove support for OLD_NEWDB (pre-1.5 version of Berkeley DB). Users + which previously defined OLD_NEWDB=1 must now upgrade to the + current version of Berkeley DB. + Added support for regular expressions using the new map class regex. + From Jan Krueger of Unix-AG of University of Hannover. + Support for BIND 8.1.1's hesiod for hesiod maps and hesiod + UserDatabases from Randall Winchester of the University + of Maryland. + Allow any shell for user shell on program deliveries on V1 + configurations for backwards compatibility on machines which + do not have getusershell(). Fix from John Beck of Sun + Microsystems. + On operating systems which change the process title by reusing the + argument vector memory, sendmail could corrupt memory if the + last argument was either "-q" or "-d". Problem noted by + Frank Langbein of the University of Stuttgart. + Support Local Mail Transfer Protocol (LMTP) between sendmail and + mail.local on the F=z flag. + Macro-expand the contents of the ErrMsgFile. Previously this was + only done if you had magic characters (0x81) to indicate + macro expansion. Now $x will be expanded. This means that + real dollar signs have to be backslash escaped. + TCP Wrappers expects "unknown" in the hostname argument if the + reverse DNS lookup for the incoming connection fails. + Problem noted by Randy Grimshaw of Syracuse University and + Wietse Venema of the Global Security Analysis Lab at + IBM T.J. Watson Research. + DSN success bounces generated from an invocation of sendmail -t + would be sent to both the sender and MAILER-DAEMON. + Problem noted by Claus Assmann of + Christian-Albrechts-University of Kiel. + Avoid "Error 0" messages on delivery mailers which exit with a + valid exit value such as EX_NOPERM. Fix from Andreas Luik + of ISA Informationssysteme GmbH. + Tokenize $&x expansions on right hand side of rules. This eliminates + the need to use tricks like $(dequote "" $&{client_name} $) + to cause the ${client_name} macro to be properly tokenized. + Add the MaxRecipientsPerMessage option: this limits the number of + recipients that will be accepted in a single SMTP + transaction. After this number is reached, sendmail + starts returning "452 Too many recipients" to all RCPT + commands. This can be used to limit the number of recipients + per envelope (in particular, to discourage use of the server + for spamming). Note: a better approach is to restrict + relaying entirely. + Fixed pointer initialization for LDAP lmap struct, fixed -s option + to ldapx map and added timeout for ldap_open call to + avoid hanging sendmail in the event of hung LDAP servers. + Patch from Booker Bense of Stanford University. + Allow multiple -qI, -qR, or -qS queue run limiters. For example, + '-qRfoo -qRbar' would deliver mail to recipients with foo or + bar in their address. Patch from Allan E Johannesen of + Worcester Polytechnic Institute. + The bestmx map will now return a list of the MX servers for a host if + passed a column delimiter via the -z map flag. This can be + used to check if the server is an MX server for the recipient + of a message. This can be used to help prevent relaying. + Patch from Mitchell Blank Jr of Exec-PC. + Mark failures for the *file* mailer and return bounce messages to the + sender for those failures. + Prevent bogus syslog timestamps on errors in sendmail.cf by + preserving the TZ environment variable until TimeZoneSpec + has been determined. Problem noted by Ralf Hildebrandt of + Technical University of Braunschweig. Patch from Per Hedeland + of Ericsson. + Print test input in address test mode when input is not from the tty + when the -v flag is given (i.e. sendmail -bt -v) to make + output easier to decipher. Problem noted by Aidan Nichol + of Procter & Gamble. + The LDAP map -s flag was not properly parsed and the error message + given included the remainder of the arguments instead of + solely the argument in error. Problem noted by Aidan Nichol + of Procter & Gamble. + New DontBlameSendmail option. This option allows administrators to + bypass some of sendmail's file security checks at the expense + of system security. This should only be used if you are + absolutely sure you know the consequences. The available + DontBlameSendmail options are: + Safe + AssumeSafeChown + ClassFileInUnsafeDirPath + ErrorHeaderInUnsafeDirPath + GroupWritableDirPathSafe + GroupWritableForwardFileSafe + GroupWritableIncludeFileSafe + GroupWritableAliasFile + HelpFileinUnsafeDirPath + WorldWritableAliasFile + ForwardFileInGroupWritableDirPath + IncludeFileInGroupWritableDirPath + ForwardFileInUnsafeDirPath + IncludeFileInUnsafeDirPath + ForwardFileInUnsafeDirPathSafe + IncludeFileInUnsafeDirPathSafe + MapInUnsafeDirPath + LinkedAliasFileInWritableDir + LinkedClassFileInWritableDir + LinkedForwardFileInWritableDir + LinkedIncludeFileInWritableDir + LinkedMapInWritableDir + LinkedServiceSwitchFileInWritableDir + FileDeliveryToHardLink + FileDeliveryToSymLink + WriteMapToHardLink + WriteMapToSymLink + WriteStatsToHardLink + WriteStatsToSymLink + RunProgramInUnsafeDirPath + RunWritableProgram + New DontProbeInterfaces option to turn off the inclusion of all the + interface names in $=w on startup. In particular, if you + have lots of virtual interfaces, this option will speed up + startup. However, unless you make other arrangements, mail + sent to those addresses will be bounced. + Automatically create alias databases if they don't exist and + AutoRebuildAliases is set. + Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. + Suggested by Christophe Wolfhugel of the Institut Pasteur. + Add PrivacyOptions=noverb flag to disable the SMTP VERB command. + When determining the client host name ($&{client_name} macro), do + a forward (A) DNS lookup on the result of the PTR lookup + and compare results. If they differ or if the PTR lookup + fails, &{client_name} will contain the IP address + surrounded by square brackets (e.g. [127.0.0.1]). + New map flag: -Tx appends "x" to lookups that return temporary failure + (i.e, it is like -ax for the temporary failure case, in + contrast to the success case). + New syntax to do limited checking of header syntax. A config line + of the form: + HHeader: $>Ruleset + causes the indicated Ruleset to be invoked on the Header + when read. This ruleset works like the check_* rulesets -- + that is, it can reject mail on the basis of the contents. + Limit the size of the HELO/EHLO parameter to prevent spammers + from hiding their connection information in Received: + headers. + When SingleThreadDelivery is active, deliveries to locked hosts + are skipped. This will cause the delivering process to + try the next MX host or queue the message if no other MX + hosts are available. Suggested by Alexander Litvin. + The [FILE] mailer type now delivers to the file specified in the + A= equate of the mailer definition instead of $u. It also + obeys all of the F= mailer flags such as the MIME + 7/8 bit conversion flags. This is useful for defining + a mailer which delivers to the same file regardless of the + recipient (e.g. 'A=FILE /dev/null' to discard unwanted mail). + Do not assume the identity of a remote connection is root@localhost + if the remote connection closes the socket before the + remote identity can be queried. + Change semantics of the F=S mailer flag back to 8.7.5 behavior. + Some mailers, including procmail, require that the real + uid is left unchanged by sendmail. Problem noted by Per + Hedeland of Ericsson. + No longer is the src/obj*/Makefile selected from a large list -- it + is now generated using the information in BuildTools/OS/ -- + some of the details are determined dynamically via + BuildTools/bin/configure.sh. + The other programs in the sendmail distribution -- mail.local, + mailstats, makemap, praliases, rmail, and smrsh -- now use + the new Build method which creates an operating system + specific Makefile using the information in BuildTools. + Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., + a failure on one message won't affect future messages to the + same host). This is necessary if the remote host sends + a 451 error if the domain of the sender does not resolve + as is common in anti-spam configurations. Problem noted + by Mitchell Blank Jr of Exec-PC. + New "discard" mailer for check_* rulesets and header checking + rulesets. If one of the above rulesets resolves to the + $#discard mailer, the commands will be accepted but the + message will be completely discarded after it is accepting. + This means that even if only one of the recipients + resolves to the $#discard mailer, none of the recipients + will receive the mail. Suggested by Brian Kantor. + All but the last cloned envelope of a split envelope were queued + instead of being delivered. Problem noted by John Caruso + of CNET: The Computer Network. + Fix deadlock situation in persistent host status file locking. + Syslog an error if a user forward file could not be read due to + an error. Patch from John Beck of Sun Microsystems. + Use the first name returned on machine lookups when canonifying a + hostname via NetInfo. Patch from Timm Wetzel of GWDG. + Clear the $&{client_addr}, $&{client_name}, and $&{client_port} + macros when delivering a bounce message to prevent + rejection by a check_compat ruleset which uses these macros. + Problem noted by Jens Hamisch of AgiX Internetservices GmbH. + If the check_relay ruleset resolves to the the error mailer, the + error in the $: portion of the resolved triplet is used + in the rejection message given to the remote machine. + Suggested by Scott Gifford of The Internet Ramp. + Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros + before calling the check_relay ruleset. Suggested by Scott + Gifford of The Internet Ramp. + Sendmail would get a segmentation fault if a mailer exited with an + exit code of 79. Problem noted by Aaron Schrab of ExecPC + Internet. Fix from Christophe Wolfhugel of the Pasteur + Institute. + Separate snprintf/vsnprintf routines into separate file for use by + mail.local. + Allow multiple map lookups on right hand side, e.g., + R$* $( host $1 $) $| $( passwd $1 $). Patch from + Christophe Wolfhugel of the Pasteur Institute. + Properly generate success DSN messages if requested for aliases + which have owner- aliases. Problem noted by Kari Hurtta + of the Finnish Meteorological Institute. + Properly display delayed-expansion macros ($&{macroname}) in + address test mode (-bt). Problem noted by Bryan Costales + of InfoBeat, Inc. + -qR could sometimes match names incorrectly. Problem noted by + Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. + Include a magic number and version in the StatusFile for the + mailstats command. + Record the number of rejected and discarded messages in the + StatusFile for display by the mailstats command. Patch + from Randall Winchester of the University of Maryland. + IDENT returns where the OSTYPE field equals "OTHER" now list the + user portion as IDENT:username@site instead of + username@site to differentiate the two. Suggested by + Kari Hurtta of the Finnish Meteorological Institute. + Enforce timeout for LDAP queries. Patch from Per Hedeland of + Ericsson. + Change persistent host status filename substitution so '/' is + replaced by ':' instead of '|' to avoid clashes. Also + avoid clashes with hostnames with leading dots. Fix from + Mitchell Blank Jr. of Exec-PC. + If the system lock table is full, only attempt to create a new + queue entry five times before giving up. Previously, it + was attempted indefinitely which could cause the partition + to run out of inodes. Problem noted by Suzie Weigand of + Stratus Computer, Inc. + In verbose mode, warn if the sendmail.cf version is less than the + currently supported version. + Sorting for QueueSortOrder=host is now case insensitive. Patch + from Randall S. Winchester of the University of Maryland. + Properly quote a full name passed via the -F command line option, + the Full-Name: header, or the NAME environment variable if + it contains characters which must be quoted. Problem noted + by Kari Hurtta of the Finnish Meteorological Institute. + Avoid possible race condition that unlocked a mail job before + releasing the transcript file on systems that use flock(2). + In some cases, this might result in a "Transcript Unavailable" + message in error bounces. + Accept SMTP replies which contain only a reply code and no + accompanying text. Problem noted by Fernando Fraticelli of + Digital Equipment Corporation. + Portability: + AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura + of Kyoto University. + AIX 4.2 requires before . Patch from + Randall S. Winchester of the University of + Maryland. + AIX 4.3 from Valdis Kletnieks of Virginia Tech CNS. + CRAY T3E from Manu Mahonen of Center for Scientific Computing + in Finland. + Digital UNIX now uses statvfs for determining free + disk space. Patch from Randall S. Winchester of + the University of Maryland. + HP-UX 11.x from Richard Allen of Opin Kerfi HF and + Regis McEwen of Progress Software Corporation. + IRIX 64 bit fixes from Kari Hurtta of the Finnish + Meteorological Institute. + IRIX 6.2 configuration fix for mail.local from Michael Kyle + of CIC/Advanced Computing Laboratory. + IRIX 6.5 from Thomas H Jones II of SGI. + IRIX 6.X load average code from Bob Mende of SGI. + QNX from Glen McCready . + SCO 4.2 and 5.x use /usr/bin instead of /usr/ucb for links + to sendmail. Install with group bin instead of kmem + as kmem does not exist. From Guillermo Freige of + Gobernacion de la Pcia de Buenos Aires and Paul + Fischer of BTG, Inc. + SunOS 4.X does not include memmove(). Patch from + Per Hedeland of Ericsson. + SunOS 5.7 includes getloadavg() function for determining + load average. Patch from John Beck of Sun + Microsystems. + CONFIG: Increment version number of config file. + CONFIG: add DATABASE_MAP_TYPE to set the default type of database + map for the various maps. The default is hash. Patch from + Robert Harker of Harker Systems. + CONFIG: new confEBINDIR m4 variable for defining the executable + directory for certain programs. + CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for + local mail delivery. By the default, /usr/libexec/mail.local + is used. This is expected to be the mail.local shipped + with 8.9 which is LMTP capable. The path is based on the + new confEBINDIR m4 variable. + CONFIG: Use confEBINDIR in determining path to smrsh for + FEATURE(smrsh). Note that this changes the default from + /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the + old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). + CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to + include $z/.forward.$w+$h and $z/.forward+$h which allow + the user to setup different .forward files for + user+detail addressing. + CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, + and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, + DontProbeInterfaces, and DontBlameSendmail options. + CONFIG: by default do not allow relaying (that is, accepting mail + from outside your domain and sending it to another host + outside your domain). + CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from + any site to any site. + CONFIG: new FEATURE(relay_entire_domain) allows any host in your + domain as defined by the 'm' class ($=m) to relay. + CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on + the MX records of the host portion of an incoming recipient. + CONFIG: new FEATURE(access_db) which turns on the access database + feature. This database give you the ability to allow + or refuse to accept mail from specified domains for + administrative reasons. By default, names that are listed + as "OK" in the access db are domain names, not host names. + CONFIG: new confCR_FILE m4 variable for defining the name of the file + used for class 'R'. Defaults to /etc/mail/relay-domains. + CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) + to add items to class 'R' ($=R) for hosts allowed to relay. + CONFIG: new FEATURE(relay_hosts_only) to change the behavior + of FEATURE(access_db) and class 'R' to lookup individual + host names only. + CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient + using % addressing is used, e.g. user%site@othersite, + and othersite is in class 'R', the check_rcpt ruleset + will strip @othersite and recheck user@site for relaying. + This feature changes that behavior. It should not be + needed for most installations. + CONFIG: new FEATURE(relay_local_from) to allow relaying if the + domain portion of the mail sender is a local host.

From Nik Conwell of Boston University. + On some non-Posix systems, the decision of whether chown(2) permits + file giveaway was undefined. From Tetsu Ushijima of the + Tokyo Institute of Technology. + Fix race condition that could cause the body of a message to be + lost (so only the header was delivered).

Based on a patch from Steve Schweinhart of + Results Computing. + If a qf file was found in a mail queue directory that had a problem + (wrong ownership, bad format, etc.) and the file name was + exactly MAXQFNAME bytes long, then instead of being tried + once, it would be tried on every queue run. Problem noted + by Bryan Costales of Mercury Mail. + If the system supports an st_gen field in the status structure, + include it when reporting that a file has changed after open. + This adds a new compile flag, HAS_ST_GEN (0/1 option). + This out to be checked as well as reported, since it is + theoretically possible for an attacker to remove a file after + it is opened and replace it with another file that has the + same i-number, but some filesystems (notably AFS) return + garbage in this field, and hence always look like the file + has changed. As a practical matter this is not a security + problem, since the files can be neither hard nor soft links, + and on no filesystem (that I am aware of) is it possible to + have two files on the same filesystem with the same i-number + simultaneously. + Delete the root Makefile from the distribution -- it is only for + use internally, and does not work at customer sites. + Fix botch that caused the second MAIL FROM: command in a single + transaction to clear the entire transaction.

This makes it possible to create a root + owned file in an arbitrary directory by inserting the symlink + into a writable directory after the initial lstat(2) check + determined that the file did not exist. The only verified + example of a system having these odd semantics for O_EXCL + and symbolic links was HP-UX prior to version 9.07. Most + systems do not have the problem, since a exclusive create + of a file disallows symbolic links. Systems that have been + verified to NOT have the problem include AIX 3.x, *BSD, + DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, + and Ultrix. This is a potential exposure on systems that + have this bug and which do not have a MAILER-DAEMON alias + pointing at a legitimate account, since this will cause old + mail to be dropped in /var/tmp/dead.letter. + SECURITY: Problems can occur on poorly managed systems, specifically, + if maps or alias files are in world writable directories. + If your system has alias maps in writable directories, it + is potentially possible for an attacker to replace the .db + (or .dir and .pag) files by symbolic links pointing at + another database; this can be used either to expose + information (e.g., by pointing an alias file at /etc/spwd.db + and probing for accounts), or as a denial-of-service attack + (by trashing the password database). The fix disallows + symbolic links entirely when rebuilding alias files or on + maps that are in writable directories, and always warns on + writable directories; 8.9 will probably consider writable + directories to be fatal errors. This does not represent an + exposure on systems that have alias files in unwritable + system directories. + SECURITY: disallow .forward or :include: files that are links (hard + or soft) if the parent directory (or any directory in the + path) is writable by anyone other than the owner. This is + similar to the previous case for user files. This change + should not affect most systems, but is necessary to prevent + an attacker who can write the directory from pointing such + files at other files that are readable only by the owner. + SECURITY: Tighten safechown rules: many systems will say that they + have a safe (restricted to root) chown even on files that + are mounted from another system that allows owners to give + away files. The new rules are very strict, trusting file + ownership only in those few cases where the system has + been verified to be at least as paranoid as necessary. + However, it is possible to relax the rules to partially + trust the ownership if the directory path is not world or + group writable. This might allow someone who has a legitimate + :include: file (referenced directly from /etc/aliases) to + become another non-root user if the :include: file is in a + non-writable directory on an NFS-mounted filesystem where + the local system says that giveaway is denied but it is + actually permitted. I believe this to be a very small set + of cases. If in doubt, do not point :include: aliases at + NFS-mounted filesystems. + SECURITY: When setting a numeric group id using the RunAsUser option + (e.g., "O RunAsUser=10:20", the group id would not be set. + Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha + group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. + The user id was still set properly. Problem noted by Uli + Pralle of the Technical University of Berlin. + Save the initial gid set for use when checking for if the + PrivacyOptions=restrictmailq option is set. Problem reported + by Wolfgang Ley of DFN-CERT. + Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a + failure on one message won't affect future messages to the + same host). + IP source route printing had an "off by one" error that would + affect any options that came after the route option. Patch + from Theo de Raadt. + The "Message is too large" error didn't successfully bounce the error + back to the sender. Problem reported by Stephen More of + PSI; patch from Gregory Neil Shapiro of WPI. + Change SMTP status code 553 to map into Extended code 5.1.0 (instead + of 5.1.3); it apparently gets used in multiple ways. + Suggested by John Myers of Portola Communications. + Fix possible extra null byte generated during collection if errors + occur at the beginning of the stream. Patch contributed by + Andrey A. Chernov and Gregory Neil Shapiro. + Code changes to avoid possible reentrant call of malloc/free within + a signal handler. Problem noted by John Beck of Sun + Microsystems. + Move map initialization to be earlier so that check_relay ruleset + will have the latest version of the map data. Problem noted + by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. + If there are fatal errors during the collection phase (e.g., message + too large) don't send the bogus message. + Avoid "cannot open xfAAA00000" messages when sending to aliases that + have errors and have owner- aliases. Problem noted by Michael + Barber of MTU; fix from Gregory Neil Shapiro of WPI. + Avoid null pointer dereference on illegal Boundary= parameters in + multipart/mixed Content-Type: header. Problem noted by + Richard Muirden of RMIT University. + Always print error messages during newaliases (-bi) even if the + ErrorMode is not set to "print". Fix from Gregory Neil + Shapiro. + Test mode could core dump if you did a /map lookup in an optional map + that could not be opened. Based on a fix from John Beck of + Sun Microsystems. + If DNS is misconfigured so that the last MX record tried points to + a host that does not have an A record, but other MX records + pointed to something reasonable, don't bounce the message + with a "host unknown" error. Note that this should really + be fixed in the zone file for the domain. Problem noted by + Joe Rhett of Navigist, Inc. + If a map fails (e.g., DNS times out) on all recipient addresses, mark + the message as having been tried; otherwise the next queue + run will not realize that this is a second attempt and will + retry immediately. Problem noted by Bryan Costales of + Mercury Mail. + If the clock is set backwards, and a MinQueueAge is set, no jobs + will be run until the later setting of the clock is reached. + "Problem" (I use the term loosely) noted by Eric Hagberg of + Morgan Stanley. + If the load average rises above the cutoff threshold (above which + sendmail will not process the queue at all) during a queue + run, abort the queue run immediately. Problem noted by + Bryan Costales of Mercury Mail. + The variable queue processing algorithm (based on the message size, + number of recipients, message precedence, and job age) was + non-functional -- either the entire queue was processed or + none of the queue was processed. The updated algorithm + does no queue run if a single recipient zero size job will + not be run. + If there is a fatal ("panic") message that will cause sendmail to + die immediately, never hold the error message for future + printing. + Force ErrorMode=print in -bt mode so that all errors are printed + regardless of the setting of the ErrorMode option in the + configuration file. Patch from Gregory Neil Shapiro. + New compile flag HASSTRERROR says that this OS has the strerror(3) + routine available in one of the libraries. Use it in conf.h. + The -m (match only) flag now works on host class maps. + If class hash or btree maps are rebuilt, sendmail will now detect + this and reopen the map. Previously, they could give + erroneous results during a single message processing + (but would recover when the next message was received). + Don't delete zero length queue files when doing queue runs until the + files are at least ten minutes old. This avoids a potential + race condition: the creator creates the qf file, getting back + a file descriptor. The queue runner locks it and deletes it + because it is zero length. The creator then writes the + descriptor that is now for a disconnected file, and the + job goes away. Based on a suggestion by Bryan Costales. + When determining the "validated" host name ($_ macro), do a forward + (A) DNS lookup on the result of the PTR lookup and compare + results. If they differ or if the PTR lookup fails, tag the + address as "may be forged". + Log null connections (i.e., hosts that connect but do not do any + substantive activity on the connection before disconnecting; + "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. + Always permit "writes" to /dev/null regardless of the link count. + This is safe because /dev/null is special cased, and no open + or write is ever actually attempted. Patch from Villy Kruse + of TwinCom. + If a message cannot be sent because of a 552 (exceeded storage + allocation) response to the MAIL FROM:<>, and a SIZE= parameter + was given, don't return the body in the bounce, since there + is a very good chance that the message will double-bounce. + Fix possible line truncation if a quoted-printable had an =00 escape + in the body. Problem noted by Charles Karney of the Princeton + Plasma Physics Laboratory. + Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. + Problem noted by Kari Hurtta of the Finnish Meteorological + Institute. + The MaxDaemonChildren option wasn't applying to queue runs as + documented. Note that this increases the potential denial + of service problems with this option: an attacker can + connect many times, and thereby lock out queue runs as well + as incoming connections. If you use this option, you should + run the "sendmail -bd" and "sendmail -q30m" jobs separately + to avoid this attack. Failure to limit noted by Matthew + Dillon of BEST Internet Communications. + Always give a message in newaliases if alias files cannot be + opened instead of failing silently. Suggested by Gregory + Neil Shapiro. This change makes the code match the O'Reilly + book (2nd edition). + Some older versions of the resolver could return with h_errno == -1 + if no name server could be reached, causing mail to bounce + instead of queueing. Treat this like TRY_AGAIN. Fix from + John Beck of SunSoft. + If a :include: file is owned by a user that does not have an entry + in the passwd file, sendmail could dereference a null pointer. + Problem noted by Satish Mynam of Sun Microsystems. + Take precautions to make sure that the SMTP protocol cannot get out + of sync if (for example) an alias file cannot be opened. + Fix a possible race condition that can cause a SIGALRM to come in + immediately after a SIGHUP, causing the new sendmail to die. + Avoid possible hang on SVr3 systems when doing child reaping. Patch + from Villy Kruse of TwinCom. + Ignore improperly formatted SMTP reply codes. Previously these were + partially processed, which could cause confusing error + returns. + Fix possible bogus pointer dereference when doing ldapx map lookups + on some architectures. + Portability: + A/UX: from Jim Jagielski of NASA/GSFC. + glibc: SOCK_STREAM was changed from a #define to an enum, + thus breaking #ifdef SOCK_STREAM. Only option seems + to be to assume SOCK_STREAM if __GNU_LIBRARY__ is + defined. Problem reported by A Sun of the University + of Washington. + Solaris: use SIOCGIFNUM to get the number of interfaces on + the system rather than guessing at compile time. + Patch contributed by John Beck of Sun Microsystems. + Intel Paragon: from Wendy Lin of Purdue University. + GNU Hurd: from Miles Bader of the GNU project. + RISC/os 4.50 from Harlan Stenn of PFCS Corporation. + ISC Unix: wait never returns if SIGCLD signals are blocked. + Unfortunately releasing them opens a race condition, + but there appears to be no fix for this. Patch from + Gregory Neil Shapiro. + BIND 8.1 for IPv6 compatibility from John Kennedy. + Solaris: a bug in strcasecmp caused characters with the + high order bit set to apparently randomly match + letters -- for example, $| (0233) matches "i" and "I". + Problem noted by John Gregson of the University of + Cambridge. + IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From + Kari Hurtta. + IRIX 6.x: Create Makefiles for systems that claim to be + IRIX64 but are 6.2 or higher (so use the regular + IRIX Makefile). + IRIX 6.x: Fix load average computation on 64 bit kernels. + Problem noted by Eric Hagberg of Morgan Stanley. + CONFIG: Some canonification was still done for UUCP-like addresses + even if FEATURE(nocanonify) was set. Problem pointed out by + Brian Candler. + CONFIG: In some cases UUCP mailers wouldn't properly recognize all + local names as local. Problem noted by Jeff Polk of BSDI; + fix provided by Gregory Neil Shapiro. + CONFIG: The "local:user" syntax entries in mailertables and other + "mailer:user" syntax locations returned an incorrect value + for the $h macro. Problem noted by Gregory Neil Shapiro. + CONFIG: Retain "+detail" information when forwarding mail to a + MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip + Guenther of Gustavus Adolphus College. + CONFIG: Make sure user+detail works for FEATURE(virtusertable); + rules are the same as for aliasing. Based on a patch from + Gregory Neil Shapiro. + CONFIG: Break up parsing rules into several pieces; this should + have no functional change in this release, but makes it + possible to have better anti-spam rulesets in the future. + CONFIG: Disallow double dots in host names to avoid having the + HostStatusDirectory store status under the wrong name. + In some cases this can be used as a denial-of-service attack. + Problem noted by Ron Jarrell of Virginia Tech, patch from + Gregory Neil Shapiro. + CONFIG: Don't use F=m (multiple recipients per invocation) for + MAILER(procmail), but do pass F=Pn9 (include Return-Path:, + don't include From_, and convert to 8-bit). Suggestions + from Kimmo Suominen and Roderick Schertler. + CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) where + being masqueraded as though FEATURE(masquerade_entire_domain) + was specified, even when it wasn't. + MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. + MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't + "slip in" a symbolic link between the lstat(2) call and the + exclusive open. This is only a problem on System V derived + systems that allow an exclusive create on files that are + symbolic links pointing nowhere. + MAIL.LOCAL: If the final mailbox close() failed, the user id was + not reset back to root, which on some systems would cause + later mailboxes to fail. Also, any partial message would + not be truncated, which could result in repeated deliveries. + Problem noted by Bruce Evans via Peter Wemm (FreeBSD + developers). + MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar + change to the sendmail map code was made in 8.8.3. Problem + noted by Gregory Neil Shapiro. + MAKEMAP: Give warnings on file problems such as map files that are + symbolic links; although makemap is not setuid root, it is + often run as root and hence has the potential for the same + sorts of problems as alias rebuilds. + MAKEMAP: Change compilation so that it will link properly on + NEXTSTEP. + CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. + Accept an optional list of arguments following the server + name for the ETRN arguments to use (instead of $=w). Other + miscellaneous bug fixes. From Christian von Roques via + John Beck of Sun Microsystems. + CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This + Perl script converts GECOS information in the /etc/passwd + file into aliases, allowing for faster access to full name + lookups; it is also clever about adding aliases (to root) + for system accounts. + NEW FILES: + src/safefile.c + cf/ostype/gnuhurd.m4 + cf/ostype/irix6.m4 + contrib/passwd-to-alias.pl + src/Makefiles/Makefile.IRIX64.6.1 + src/Makefiles/Makefile.IRIX64.6.x + RENAMED FILES: + src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x + src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 + +8.8.5/8.8.5 97/01/21 + SECURITY: Clear out group list during startup. Without this, sendmail + will continue to run with the group permissions of the caller, + even if RunAsUser is specified. + SECURITY: Make purgestat (-bH) be root-only. This is not in response + to any known attack, but it's best to be conservative. + Suggested by Peter Wemm of DIALix. + SECURITY: Fix buffer overrun problem in MIME code that has possible + security implications. Patch from Alex Garthwaite of the + University of Pennsylvania. + Use of a -f flag with a phrase attached (e.g., "-f 'Full Name '") + would truncate the address after "Full". Although the -f + syntax is incorrect (since it is in the envelope, it + shouldn't have comments and full names), the failure mode + was unnecessarily awful. + Fix a possible null pointer dereference when converting 8-bit data + to a 7-bit format. Problem noted by Jim Hutchins of + Sandia National Labs and David James of British Telecom. + Clear out stale state that affected F=9 on SMTP mailers in queue + runs. Although this really shouldn't be used (F=9 is for + final delivery only, and using it on an SMTP mailer makes + it possible for a message to be converted from 8->7->8->7 + bits several times), it shouldn't have failed with a syserr. + Problem noted by Eric Hagberg of Morgan Stanley. + _Really_ fix the multiple :maildrop code in the user database + module. Patch from Roy Mongiovi of Georgia Tech. + Let F lines in the configuration file actually read root-only + files if the configuration file is safe. Based on a + patch from Keith Reynolds of SCO. + ETRN followed by QUIT would hold the connection open until the queue + run completed. Problem noted by Truck Lewis of TDK + Semiconductor Corp. + It turns out that despite the documentation, the TCP wrappers library + does _not_ log rejected connections. Do the logging ourselves. + Problem noted by Fletcher Mattox of the University of Texas + at Austin. + If sendmail finds a qf file in its queue directory that is an unknown + version (e.g., when backing out to an old version), the + error is reported on every queue run. Change it to only + give the error once (and rename the qf => Qf). Patch from + William A. Gianopoulos of Raytheon Company. + Start a new session when doing background delivery; currently it + ignored signals but didn't start a new signal, that caused + some problems if a background process tried to send mail + under certain circumstances. Problem noted by Eric Hagberg + of Morgan Stanley; fix from Kari Hurtta. + Simplify test for skipping a queue run to just check if the current + load average is >= the queueing load average. Previously + the check factored in some other parameters that caused it + to essentially never skip the queue run. Patch from Bryan + Costales. + If the SMTP server is running in "nullserver" mode (that is, it is + rejecting all commands), start sleeping after MAXBADCOMMAND + (25) commands; this helps prevent a bad guy from putting + you into a tight loop as a denial-of-service attack. Based + on an e-mail conversation with Brad Knowles of AOL. + Slow down when too many "light weight" commands have been issued; + this helps prevent a class of denial-of-service attacks. + The current values and defaults are: + MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR + MAXHELOCOMMANDS 3 HELO, EHLO + MAXVRFYCOMMANDS 6 VRFY, EXPN + MAXETRNCOMMANDS 8 ETRN + These will probably be configurable in a future release. + On systems that have uid_t typedefed to be an unsigned short, programs + that had the F=S flag and no U= equate would be invoked with + the real uid set to 65535 rather than being left unchanged. + In some cases, NOTIFY=NEVER was not being honored. Problem noted + by Steve Hubert of the University of Washington, Seattle. + Mail that was Quoted-Printable encoded and had a soft line break on + the last line (i.e., an incomplete continuation) had the last + line dropped. Since this appears to be illegal it isn't + clear what to do with it, but flushing the last line seems + to be a better "fail soft" approach. Based on a patch from + Eric Hagberg. + If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a + bogus HELO command still causes the "Polite people say HELO + first" error message. Problem pointed out by Chris Thomas + of UCLA; patch from John Beck of SunSoft. + Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set + in PrivacyFlags. The -q shouldn't turn this command off. + Problem noted by Murray Kucherawy of Pacific Bell Internet; + based on a patch from Gregory Neil Shapiro of WPI. + Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) + in a DATA transaction to be sticky; these can occur because + a message is too large, and smaller messages should still go + through. Problem noted by Matt Dillon of Best Internet + Communications. + In some cases bounces were saved in /var/tmp/dead.letter even if they + had been successfully delivered to the envelope sender. + Problem noted Eric Hagberg of Morgan Stanley; solution from + Gregory Neil Shapiro of WPI. + Give better diagnostics on long alias lines. Based on code contributed + by Patrick Gosling of the University of Cambridge. + Increase the number of virtual interfaces that will be probed for + alternate names. Problem noted by Amy Rich of Shore.Net. + PORTABILITY: + UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from + Toshiaki Nomura of Fujitsu Limited. + SunOS with LDAP support: compile problems with struct timeval. + Patch from Nick Cuccia of TCSI Corporation. + SCO: from Keith Reynolds of SCO. + Solaris: kstat load average computation wasn't being used. + Fixes from Michael Ju. Tokarev of Telecom Service, JSC + (Moscow). + OpenBSD: from Jason Downs of teeny.org. + Altos System V: from Tim Rice. + Solaris 2.5: from Alan Perry of SunSoft. + Solaris 2.6: from John Beck of SunSoft. + Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli + of Pratt & Whitney . + CONFIG: It seems that I hadn't gotten the Received: line syntax + _just_right_ yet. Tweak it again. I'll omit the names + of the "contributors" (quantity two) in this one case. + As of now, NO MORE DISCUSSION about the syntax of the + Received: line. + CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), + it never inserts that class into the output file. Fix it + so it will honor EXPOSED_USER but will _not_ include root + automatically in this class. Problem noted by Ronan KERYELL + of Centre de Recherche en Informatique de l'École Nationale + Supérieure des Mines de Paris (CRI-ENSMP). + CONFIG: Clean up handling of "local:" syntax in relay specifications + such as LUSER_RELAY. This change permits the following + syntaxes: ``local:'' will send to the same user on the + local machine (e.g., in a mailertable entry for "host", + ``local:'' will cause an address addressed to user@host to + go to user on the local machone). ``local:user'' will send + to the named user on the local machine. ``local:user@host'' + is equivalent to ``local:user'' (the host is ignored). In + all cases, the original user@host is passed in $@ (i.e., the + detail information). Inspired by a report from Michael Fuhr. + CONFIG: Strip quotes from the first word of an "error:" host + indication. This lets you set (for example) the LUSER_RELAY + to be ``error:\"5.1.1\" Your Message Here''. Note the use + of the \" so that the resulting string is properly quoted. + Problem noted by Gregory Neil Shapiro of WPI. + OP.ME: documentation was inconsistent about whether sendmail did a + NOOP or a RSET to probe the connection (it does a RSET). + Inconsistency noted by Deeran Peethamparam. + OP.ME: insert additional blank pages so it will print properly on + a duplex printer. From Matthew Black of Cal State University, + Long Beach. + +8.8.4/8.8.4 96/12/02 + SECURITY: under some circumstances, an attacker could get additional + permissions by hard linking to files that were group + writable by the attacker. The solution is to disallow any + files that have hard links -- this will affect .forward, + :include:, and output files. Problem noted by Terry + Kyriacopoulos of Interlog Internet Services. As a + workaround, set UnsafeGroupWrites -- always a good idea. + SECURITY: the TryNullMXList (w) option should not be safe -- if it + is, it is possible to do a denial-of-service attack on + MX hosts that rely on the use of the null MX list. There + is no danger if you have this option turned off (the default). + Problem noted by Dan Bernstein. Also, make the DontInitGroups + unsafe. I know of no specific attack against this, although + a denial-of-service attack is probably possible, but in theory + you should not be able to safely tweak anything that affects + the permissions that are used when mail is delivered. + Purgestat could go into an infinite loop if one of the host status + directories somehow became empty. Problem noted by Roy + Mongiovi of Georgia Tech. + Processes got "lost" when counting children due to a race condition. + This caused "proc_list_probe: lost pid" messages to be logged. + Problem noted by several people. + On systems with System V SIGCLD child signal semantics (notably AIX + and HP-UX), mail transactions would print the message "451 + SMTP-MAIL: lost child: No child processes". Problem noted + by several people. + Miscellaneous compiler warnings on picky compilers (or when setting + gcc to high warning levels). From Tom Moore of NCR Corp. + SMTP protocol errors, and most errors on MAIL FROM: lines should + not be persistent between runs, since they are based on the + message rather than the host. Problem noted by Matt Dillon + of Best Internet Communications. + The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore + of NCR (a.k.a., AT&T Global Information Solutions). + Avoid the possibility of having a child daemon run to completion + (including closing the SMTP socket) before the parent has + had a chance to close the socket; this can cause the parent + to hang for a long time waiting for the socket to drain. + Patch from Don Lewis of TDK Semiconductor. + If the fork() failed in a queue run, the queue runners would not be + rescheduled (so queue runs would stop). Patch from Don Lewis. + Some error conditions in ETRN could cause output without an SMTP + status code. Problem noted by Don Lewis. + Multiple :maildrop addresses in the user database didn't work properly. + Patch from Roy Mongiovi of Georgia Tech. + Add ".db" automatically onto any user database spec that does not + already have it; this is for consistency with makemap, the + K line, and the documentation. Inconsistency pointed out + by Roy Mongiovi. + Allow sendmail to be properly called in nohup mode. Patch from + Kyle Jones of UUNET. + Change ETRN to ignore but still update host status files; previously + it would ignore them and not save the updated status, which + caused stale information to be maintained. Based on a patch + from Christopher Davis of Kapor Enterprises Inc. Also, have + ETRN ignore the MinQueueAge option. + Patch long term host status to recover more gracefully from an empty + host status file condition. Patch from NAKAMURA Motonori + of Kyoto University. + Several patches to signal handling code to fix potential race + conditions from Don Lewis. + Make it possible to compile with -DDAEMON=0 (previously it had some + compile errors). This turns DAEMON, QUEUE, and SMTP into + 0/1 compilation flags. Note that DAEMON is an obsolete + compile flag; use NETINET instead. Solution based on a + patch from Bryan Costales. + PORTABILITY FIXES: + AIX4: getpwnam() and getpwuid() do a sequential scan of the + /etc/security/passwd file when called as root. This + is very slow on some systems. To speed it up, use the + (undocumented) _getpw{nam,uid}_shadow() routines. + Patch from Chris Thomas of UCLA/OAC Systems Group. + SCO 5.x: include -lprot in the Makefile.

Murrell of InterLinx Support + Services, Inc. + Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. + I believe this to have only been a problem if you + compiled with -DUSE_VENDOR_CF_PATH -- another reason + to stick with /etc/sendmail.cf as your One True Path. + Digital UNIX (OSF/1 on Alpha) load average computation from + Martin Laubach of the Technischen Universität Wien. + CONFIG: change default Received: line to be multiple lines rather + than one long one. By popular demand. + MAIL.LOCAL: warnings weren't being logged on some systems. Patch + from Jerome Berkman of U.C.

Problem noted + by Leshka Zakharoff on the + best-of-security list. + Log sendmail binary version number in "Warning: .cf version level + (%d) exceeds program functionality (%d) message" -- this + should make it clearer to people that they are running + the wrong binary. + Fix a problem that occurs when you open an SMTP connection and then + do one or more ETRN commands followed by a MAIL command; at + the end of the DATA phase sendmail would incorrectly report + "451 SMTP-MAIL: lost child: No child processes". Problem + noted by Eric Bishop of Virginia Tech. + When doing text-based host canonification (typically /etc/hosts + lookup), a null host name would match any /etc/hosts entry + with space at the end of the line. Problem noted by Steve + Hubert of the University of Washington, Seattle. + 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. + Problem reported by Tom Smith of Digital Equipment Corp. + Increase the size of the DNS answer buffer -- the standard UDP packet + size PACKETSZ (512) is not sufficient for some nameserver + answers containing very many resource records. The resolver + may also switch to TCP and retry if it detects UDP packet + overflow. Also, allow for the fact that the resolver + routines res_query and res_search return the size of the + *un*truncated answer in case the supplied answer buffer it + not big enough to accommodate the entire answer. Patch from + Eric Wassenaar. + Improvements to MaxDaemonChildren code. If you think you have too + many children, probe the ones you have to verify that they + are still around. Suggested by Jared Mauch of CICnet, Inc. + Also, do this probe before growing the vector of children + pids; this previously caused the vector to grow indefinitely + due to a race condition. Problem reported by Kyle Jones of + UUNET. + On some architectures, (from the Berkeley DB library) defines + O_EXLOCK to zero; this fools the map compilation code into + thinking that it can avoid race conditions by locking on open. + Change it to check for O_EXLOCK non-zero. Problem noted by + Leif Erlingsson of Data Lege. + Always call res_init() on startup (if compiled in, of course) to + allow the sendmail.cf file to tweak resolver flags; without + it, flag tweaks in ResolverOptions are ignored. Patch from + Andrew Sun of Merrill Lynch. + Improvements to host status printing code. Suggested by Steve Hubert + of the University of Washington, Seattle. + Change MinQueueAge option processing to do the check for the job age + when reading the queue file, rather than at the end; this + avoids parsing the addresses, which can do DNS lookups. + Problem noted by John Beck of InReference, Inc. + When MIME was being 7->8 bit decoded, "From " lines weren't being + properly escaped. Problem noted by Peter Nilsson of the + University of Linkoping. + In some cases, sendmail would retain root permissions during queue + runs even if RunAsUser was set. Problem noted by Mark + Thomas of Mark G. Thomas Consulting. + If the F=l flag was set on an SMTP mailer to indicate that it is + actually local delivery, and NOTIFY=SUCCESS is specified in + the envelope, and the receiving SMTP server speaks DSN, then + the DSN would be both generated locally and propagated to the + other end. + The U= mailer field didn't correctly extract the group id if the + user id was numeric. Problem noted by Kenneth Herron of + MCI Telecommunications Communications. + If a message exceeded the fixed maximum size on input, the body of + the message was included in the bounce. Note that this did + not occur if it exceeded the maximum _output_ size. Problem + reported by Kyle Jones of UUNET. + PORTABILITY FIXES: + AIX4: 4.1 doesn't have a working setreuid(2); change the + AIX4 defines to use seteuid(2) instead, which + works on 4.1 as well as 4.2. Problem noted by + Håkan Lindholm of interAF, Sweden. + AIX4: use tzname[] vector to determine time zone name. + Patch from NAKAMURA Motonori of Kyoto University. + MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. + Contributed by Paul DuBois . + Solaris: kstat(3k) support for retrieving the load average. + This adds the LA_KSTAT definition for LA_TYPE. + The outline of the implementation was contributed + by Michael Tokarev of Telecom Service, JSC, Moscow. + HP-UX 10.0 gripes about the (perfectly legal!) forward + declaration of struct rusage at the top of conf.h; + change it to only be included if you are using gcc, + which is apparently the only compiler that requires + it in the first place. Problem noted by Jeff + Earickson of Colby College. + IRIX: don't default to using gcc. IRIX is a civilized + operating system that comes with a decent compiler + by default. Problem noted by Barry Bouwsma and + Kari Hurtta. + CONFIG: specify F=9 as default in FEATURE(local_procmail) for + consistency with other local mailers. Inconsistency + pointed out by Teddy Hogeborn . + CONFIG: if the "limited best mx" feature is used (to reduce DNS + overhead) as part of the bestmx_is_local feature, the + domain part was dropped from the name. Patch from Steve + Hubert of the University of Washington, Seattle. + CONFIG: catch addresses of the form "user@.dom.ain"; these could + end up being translated to the null host name, which would + return any entry in /etc/hosts that had a space at the end + of the line. Problem noted by Steve Hubert of the + University of Washington, Seattle. + CONFIG: add OSTYPE(aix4).

Problem noted + by Dan Bernstein of the University of Illinois at Chicago. + SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain + message could overflow a buffer if it was converted back + to 8 bits. This caused core dumps and has the potential + for a remote attack. Problem first noted by Gregory Shapiro + of WPI. + Avoid duplicate deliveries of error messages on systems that don't + have flock(2) support. Patch from Motonori Nakamura of + Kyoto University. + Ignore null FallBackMX (V) options. If this option is null (as + opposed to undefined) it can cause "null signature" syserrs + on illegal host names. + If a Base64 encoded text/plain message has no trailing newline in + the encoded text, conversion back to 8 bits will drop the + final line. Problem noted by Pierre David. + If running with a RunAsUser, sendmail would give bogus "cannot + setuid" (or seteuid, or setreuid) messages on some systems. + Problem pointed out by Jordan Mendelson of Web Services, Inc. + Always print error messages in -bv mode -- previously, -bv would + be absolutely silent on errors if the error mode was sent + to (say) mail-back. Problem noted by Kyle Jones of UUNET. + If -qI/R/S is set (or the ETRN command is used), ignore all long + term host status. This is necessary because it is common + to do this when you know a host has just come back up. + Disallow duplicate HELO/EHLO commands as required by RFC 1651 section + 4.2. Excessive permissiveness noted by Lee Flight of the + University of Leicester. + If a service (such as NIS) is specified as the last entry in the + service switch, but that service is not compiled in, sendmail + would return a temporary failure when an entry was not found + in the map. This caused the message to be queued instead of + bouncing immediately. Problem noted by Harry Edmon of the + University of Washington. + PORTABILITY FIXES: + Solaris 2.3 had compilation problems in conf.c. Several + people pointed this out. + NetBSD from Charles Hannum of MIT. + AIX4 improvements based on info from Steve Bauer of South + Dakota School of Mines & Technology. + CONFIG: ``error:code message'' syntax was broken in virtusertable. + Patch from Gil Kloepfer Jr. + CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set + using MASQUERADE_DOMAIN) were not masqueraded unless they + were also in $=w. Problem noted by Zoltan Basti of + Softec. + MAIL.LOCAL: patches to compile and link cleanly on AIX.

Pointed out by Jonathan Kamens of OpenVision. + Log a warning if the sendmail daemon is invoked without a full + pathname, which prevents "kill -1" from working. I was + urged to put this in by Andrey A. Chernov of DEMOS (Russia). + Fix small buffer overflow. Since the data in this buffer was not + read externally, there was no security problem (and in fact + probably wouldn't really overflow on most compilers). Pointed + out by KIZU takashi of Osaka University. + Fix problem causing domain literals such as [1.2.3.4] to be ignored + if a FallbackMXHost was specified in the configuration file + -- all mail would be sent to the fallback even if the original + host was accessible. Pointed out by Munenari Hirayama of + NSC (Japan). + A message that didn't terminate with a newline would (sometimes) not + have the trailing "." added properly in the SMTP dialogue, + causing SMTP to hang. Patch from Per Hedeland of Ericsson. + The DaemonPortOptions suboption to bind to a particular address was + incorrect and nonfunctional due to a misunderstanding of the + semantics of binding on a passive socket. Patch from + NIIBE Yutaka of Mitsubishi Research Institute. + Increase the number of MX hosts for a single name to 100 to better + handle the truly huge service providers such as AOL, which + has 13 at the moment (and climbing). In order to avoid + trashing memory, the buffer for all names has only been + slightly increased in size, to 12.8K from 10.2K -- this means + that if a single name had 100 MX records, the average size + of those records could not exceed 128 bytes. Requested by + Brad Knowles of America On Line. + Restore use of IDENT returns where the OSTYPE field equals "OTHER". + Urged by Dan Bernstein of U.C. Berkeley. + Print q_statdate and q_specificity in address structure debugging + printout. + Expand MCI structure flag bits for debugging output. + Support IPv6-style domain literals, which can have colons between + square braces. + Log open file descriptors for the "cannot dup" messages in deliver(); + this is an attempt to track down a bug that one person seems + to be having (it may be a Solaris bug!). + DSN NOTIFY parameters were not properly propagated across queue runs; + this caused the NOTIFY info to sometimes be lost. Problem + pointed out by Claus Assmann of the + Christian-Albrechts-University of Kiel. + The statistics gathered in the sendmail.st file were too high; in + some cases failures (e.g., user unknown or temporary failure) + would count as a delivery as far as the statistics were + concerned. Problem noted by Tom Moore of AT&T GIS. + Systems that don't have flock() would not send split envelopes in + the initial run. Problem pointed out by Leonard Zubkoff of + Dandelion Digital. + Move buffer overflow checking -- these primarily involve distrusting + results that may come from NIS and DNS. + 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't + include and hence had the wrong pathnames for a few + things like /var/tmp. Reported by Matthew Green. + Conditions were reversed for the Priority: header, resulting in all + values being interpreted as non-urgent except for non-urgent, + which was interpreted as normal. Patch from Bryan Costales. + The -o (optional) flag was being ignored on hash and btree maps + since 8.7.2. Fix from Bryan Costales. + Content-Types listed in class "q" will always be encoded as + Quoted-Printable (or more accurately, will never be encoded + as base64). The class can have primary types (e.g., "text") + or full types (e.g., "text/plain"). Based on a suggestion by + Marius Olafsson of the University of Iceland. + Define ${envid} to be the original envelope id (from the ESMTP DSN + dialogue) so it can be passed to programs in mailers. + Define ${bodytype} to be the body type (from the -B flag or the + BODY= ESMTP parameter) so it can be passed to programs in + mailers. + Cause the VRFY command to return 252 instead of 250 unless the F=q + flag is set in the mailer descriptor. Suggested by John + Myers of CMU. + Implement ESMTP ETRN command to flush the queue for a specific host. + The command takes a host name; data for that host is + immediately (and asynchronously) flushed. Because this shares + the -qR implementation, other hosts may be attempted, but + there should be no security implications. Implementation + from John Beck of InReference, Inc. See RFC 1985 for details. + Add three new command line flags to pass in DSN parameters: -V envid + (equivalent to ENVID=envid on the MAIL command), -R ret + (equivalent to RET=ret on the MAIL command), and -Nnotify + (equivalent to NOTIFY=notify on the RCPT command). Note + that the -N flag applies to all recipients; there is no way + to specify per-address notifications on the command line, + nor is there an equivalent for the ORCPT= per-address + parameter. + Restore LogLevel option to be safe (it can only be increased); + apparently I went into paranoid mode between 8.6 and 8.7 + and made it unsafe. Pointed out by Dabe Murphy of the + University of Maryland. + New logging on log level 15: all SMTP traffic. Patches from + Andrew Gross of San Diego Supercomputer Center. + NetInfo property value searching code wasn't stopping when it found + a match. This was causing the wrong values to be found (and + had a memory leak). Found by Bastian Schleuter of TU-Berlin. + Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed + out by Bill Wisner of Electronics for Imaging that you can't + use the bracket address form for the MAIL_HUB macro, since + that causes the brackets to remain in the envelope recipient + address used for delivery. The simple fix (stripping off the + brackets in the config file) breaks the use of IP literal + addresses. This flag will solve that problem. + Add MustQuoteChars option. This is a list of characters that must + be quoted if they are found in the phrase part of an address + (that is, the full name part). The characters @,;:\()[] are + always in this list and cannot be removed. The default is + this list plus . and ' to match RFC 822. + Add AllowBogusHELO option; if set, sendmail will allow HELO commands + that do not include a host name for back compatibility with + some stupid SMTP clients. Setting this violates RFC 1123 + section 5.2.5. + Add MaxDaemonChildren option; if this is set, sendmail will start + rejecting connections if it has more than this many + outstanding children accepting mail. Note that you may + see more processes than this because of outgoing mail; this + is for incoming connections only. + Add ConnectionRateThrottle option. If set to a positive value, the + number of incoming SMTP connections that will be permitted + in a single second is limited to this number. Connections are + not refused during this time, just deferred. The intent is to + flatten out demand so that load average limiting can kick in. + It is less radical than MaxDaemonChildren, which will stop + accepting connections even if all the connections are idle + (e.g., due to connection caching). + Add Timeout.hoststatus option. This interval (defaulting to 30m) + specifies how long cached information about the state of a + host will be kept before they are considered stale and the + host is retried. If you are using persistent host status + (i.e., the HostStatusDirectory option is set) this will apply + between runs; otherwise, it applies only within a single queue + run and hence is useful only for hosts that have large queues + that take a very long time to run. + Add SingleLineFromHeader option. If set, From: headers are coerced + into being a single line even if they had newlines in them + when read. This is to get around a botch in Lotus Notes. + Text class maps were totally broken -- if you ever retrieved the last + item in a table it would be truncated. Problem noted by + Gregory Neil Shapiro of WPI. + Extend the lines printed by the mailq command (== the -bp flag) when + -v is given to 120 characters; this allows more information + to be displayed. Suggested by Gregory Neil Shapiro of WPI. + Allow macro definitions (`D' lines) with unquoted commas; previously + this was treated as end-of-input. Problem noted by Bryan + Costales. + The RET= envelope parameter (used for DSNs) wasn't properly written + to the queue file. Fix from John Hughes of Atlantic + Technologies, Inc. + Close /var/tmp/dead.letter after a successful write -- otherwise + if this happens in a queue run it can cause nasty delays. + Problem noted by Mark Horton of AT&T. + If userdb entries pointed to userdb entries, and there were multiple + values for a given key, the database cursor would get + trashed by the recursive call. Problem noted by Roy Mongiovi + of Georgia Tech. Fixed by reading all the values and creating + a comma-separated list; thus, the -v output will be somewhat + different for this case. + Fix buffer allocation problem with Hesiod-based userdb maps when + HES_GETMAILHOST is defined. Based on a patch by Betty Lee + of Stanford University. + When envelopes were split due to aliases with owner- aliases, and + there was some error on one of the lists, more than one of + the owners would get the message. Problem pointed out by + Roy Mongiovi of Georgia Tech. + Detect excessive recursion in macro expansions, e.g., $X defined + in terms of $Y which is defined in terms of $X. Problem + noted by Bryan Costales; patch from Eric Wassenaar. + When using F=U to get "ugly UUCP" From_ lines, a buffer could in + some cases get trashed causing bogus From_ lines. Fix from + Kyle Jones of UUNET. + When doing load average initialization, if the nlist call for avenrun + failed, the second and subsequent lookups wouldn't notice + that fact causing bogus load averages to be returned. Noted + by Casper Dik of Sun Holland. + Fix problem with incompatibility with some versions of inet_aton that + have changed the return value to unsigned, so a check for an + error return of -1 doesn't work. Use INADDR_NONE instead. + This could cause mail to addresses such as [foo.com] to bounce + or get dropped. Problem noted by Christophe Wolfhugel of the + Pasteur Institute. + DSNs were inconsistent if a failure occurred during the DATA phase + rather than the RCPT phase: the Action: would be correct, but + the detailed status information would be wrong. Problem noted + by Bob Snyder of General Electric Company. + Add -U command line flag and the XUSR ESMTP extension, both indicating + that this is the initial MUA->MTA submission. The flag current + does nothing, but in future releases (when MUAs start using + these flags) it will probably turn on things like DNS + canonification. + Default end-of-line string (E= specification on mailer [M] lines) + to \r\n on SMTP mailers. Default remains \n on non-SMTP + mailers. + Change the internal definition for the *file* and *include* mailers + to have $u in the argument vectors so that they aren't + misinterpreted as SMTP mailers and thus use \r\n line + termination. This will affect anyone who has redefined + either of these in their configuration file. + Don't assume that IDENT servers close the connection after a query; + responses can be newline terminated. From Terry Kennedy of + St. Peter's College. + Avoid core dumps on erroneous configuration files that have + $#mailer with nothing following. From Bryan Costales. + Avoid null pointer dereference with high debug values in unlockqueue. + Fix from Randy Martin of Clemson University. + Fix possible buffer overrun when expanding very large macros. Fix + from Kyle Jones of UUNET. + After 25 EXPN or VRFY commands, start pausing for a second before + processing each one. This avoids a certain form of denial + of service attack. Potential attack pointed out by Bryan + Costales. + Allow new named (not numbered!) config file rules to do validity + checking on SMTP arguments: check_mail for MAIL commands and + check_rcpt for RCPT commands. These rulesets can do anything + they want; their result is ignored unless they resolve to the + $#error mailer, in which case the indicated message is printed + and the command is rejected. Similarly, the check_compat + ruleset is called before delivery with "from_addr $| to_addr" + (the $| is a meta-symbol used to separate the two addresses); + it can give a "this sender can't send to this recipient" + notification. Note that this patch allows $| to stand alone + in rulesets. + Define new macros ${client_name}, ${client_addr}, and ${client_port} + that have the name, IP address, and port number (respectively) + of the SMTP client (that is, the entity at the other end of + the connection. These can be used in (e.g.) check_rcpt to + verify that someone isn't trying to relay mail through your + host inappropriately. Be sure to use the deferred evaluation + form, for example $&{client_name}, to avoid having these bound + when sendmail reads the configuration file. + Add new config file rule check_relay to check the incoming connection + information. Like check_compat, it is passed the host name + and host address separated by $| and can reject connections + on that basis. + Allow IDA-style recursive function calls. Code contributed by Mark + Lovell and Paul Vixie. + Eliminate the "No ! in UUCP From address!" message" -- instead, create + a virtual UUCP address using either a domain address or the $k + macro. Based on code contributed by Mark Lovell and Paul + Vixie. + Add Stanford LDAP map. Requires special libraries that are not + included with sendmail. Contributed by Booker C. Bense + ; contact him for support. + See also the src/READ_ME file. + Allow -dANSI to turn on ANSI escape sequences in debug output; this + puts metasymbols (e.g., $+) in reverse video. Really useful + only for debugging deep bits of code where it is important to + distinguish between the single-character metasymbol $+ and the + two characters $, +. + Changed ruleset 89 (executed in dumpstate()) to a named ruleset, + debug_dumpstate. + Add new UnsafeGroupWrites option; if set, .forward and :include: + files that are group writable are considered "unsafe" -- that + is, programs and files referenced from such files are not + valid recipients. + Delete bogosity test for FallBackMX host; this prevented it to be a + name that was not in DNS or was a domain-literal. Problem + noted by Tom May. + Change the introduction to error messages to more clearly delineate + permanent from temporary failures; if both existed in a + single message it could be confusing. Suggested by John + Beck of InReference, Inc. + The IngoreDot (i) option didn't work for lines that were terminated + with CRLF. Problem noted by Ted Stockwell of Secure + Computing Corporation. + Add a heuristic to improve the handling of unbalanced `<' signs in + message headers. Problem reported by Matt Dillon of Best + Internet Communications. + Check for bogus characters in the 0200-0237 range; since these are + used internally, very strange errors can occur if those + characters appear in headers. Problem noted by Anders Gertz + of Lysator. + Implement 7 -> 8 bit MIME conversions. This only takes place if the + recipient mailer has the F=9 flag set, and only works on + text/plain body types. Code contributed by Marius Olafsson + of the University of Iceland. + Special case "postmaster" name so that it is always treated as lower + case in alias files regardless of configuration settings; + this prevents some potential problems where "Postmaster" or + "POSTMASTER" might not match "postmaster". In most cases + this change is a no-op. + The -o map flag was ignored for text maps. Problem noted by Bryan + Costales. + The -a map flag was ignored for dequote maps. Problem noted by + Bryan Costales. + Fix core dump when a lookup of a class "prog" map returns no + response. Patch from Bryan Costales. + Log instances where sendmail is deferring or rejecting connections + on LogLevel 14. Suggested by Kyle Jones of UUNET. + Include port number in process title for network daemons. Suggested + by Kyle Jones of UUNET. + Send ``double bounces'' (errors that occur when sending an error + message) to the address indicated in the DoubleBounceAddress + option (default: postmaster). Previously they were always + sent to postmaster. Suggested by Kyle Jones of UUNET. + Add new mode, -bD, that acts like -bd in all respects except that + it runs in foreground. This is useful for using with a + wrapper that "watches" system services. Suggested by Kyle + Jones of UUNET. + Fix botch in spacing around (parenthesized) comments in addresses + when the comment comes before the address. Patch from + Motonori Nakamura of Kyoto University. + Use the prefix "Postmaster notify" on the Subject: lines of messages + that are being bounced to postmaster, rather than "Returned + mail". This permits the person who is postmaster more + easily determine what messages are to their role as + postmaster versus bounces to mail they actually sent. Based + on a suggestion by Motonori Nakamura. + Add new value "time" for QueueSortOrder option; this causes the queue + to be sorted strictly by the time of submission. Note that + this can cause very bad behaviour over slow lines (because + large jobs will tend to delay small jobs) and on nodes with + heavy traffic (because old things in the queue for hosts that + are down delay processing of new jobs). Also, this does not + guarantee that jobs will be delivered in submission order + unless you also set DeliveryMode=queue. In general, it should + probably only be used on the command line, and only in + conjunction with -qRhost.domain. In fact, there are very few + cases where it should be used at all. Based on an + implementation by Motonori Nakamura. + If a map lookup in ruleset 5 returns tempfail, queue the message in + the same manner as other rulesets. Previously a temporary + failure in ruleset 5 was ignored. Patch from Booker Bense + of Stanford University. + Don't proceed to the next MX host if an SMTP MAIL command returns a + 5yz (permanent failure) code. The next MX host will still be + tried if the connection cannot be opened in the first place + or if the MAIL command returns a 4yz (temporary failure) code. + (It's hard to know what to do here, since neither RFC 974 nor + RFC 1123 specify when to proceed to the next MX host.) + Suggested by Jonathan Kamens of OpenVision, Inc. + Add new "-t" flag for map definitions (the "K" line in the .cf file). + This causes map lookups that get a temporary failure (e.g., + name server failure) to _not_ defer the delivery of the + message. This should only be used if your configuration file + is prepared to do something sensible in this case. Based on + an idea by Gregory Shapiro of WPI. + Fix problem finding network interface addresses. Patch from + Motonori Nakamura. + Don't reject qf entries that are not owned by your effective uid if + you are not running setuid; this makes management of certain + kinds of firewall setups difficult. Patch suggested by + Eamonn Coleman of Qualcomm. + Add persistent host status. This keeps the information normally + maintained within a single queue run in disk files that are + shared between sendmail instances. The HostStatusDirectory + is the directory in which the information is maintained. If + not set, persistent host status is turned off. If not a full + pathname, it is relative to the queue directory. A common + value is ".hoststat". + There are also two new operation modes: + * -bh prints the status of hosts that have had recent + connections. + * -bH purges the host statuses. No attempt is made to save + recent status information. + This feature was originally written by Paul Vixie of Vixie + Enterprises for KJS and adapted for V8 by Mark Lovell of + Bigrock Consulting. Paul's funding of Mark and Mark's patience + with my insistence that things fit cleanly into the V8 + framework is gratefully appreciated. + New SingleThreadDelivery option (requires HostStatusDirectory to + operate). Avoids letting two sendmails on the local machine + open connections to the same remote host at the same time. + This reduces load on the other machine, but can cause mail to + be delayed (for example, if one sendmail is delivering a huge + message, other sendmails won't be able to send even small + messages). Also, it requires another file descriptor (for the + lock file) per connection, so you may have to reduce + ConnectionCacheSize to avoid running out of per-process + file descriptors. Based on the persistent host status code + contributed by Paul Vixie and Mark Lovell. + Allow sending to non-simple files (e.g., /dev/null) even if the + SafeFileEnvironment option is set. Problem noted by Bryan + Costales. + The -qR flag mistakenly matched flags in the "R" line of the queue + file. Problem noted by Bryan Costales. + If a job was aborted using the interrupt signal (e.g., control-C from + the keyboard), on some occasions an empty df file would be + left around; these would collect in the queue directory. + Problem noted by Bryan Costales. + Change the makesendmail script to enhance the search for Makefiles + based on release number. For example, on SunOS 5.5.1, it will + search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then + Makefile.SunOS.5.x (in addition to the other rules, e.g., + adding $arch). Problem noted by Jason Mastaler of Atlanta + Webmasters. + When creating maps using "newaliases", always map the keys to lower + case when creating the map unless the -f flag is specified on + the map itself. Previously this was done based on the F=u + flag in the local mailer, which meant you could create aliases + that you could never access. Problem noted by Bob Wu of DEC. + When a job was read from the queue, the bits causing notification on + failure or delay were always set. This caused those + notifications to be sent even if NOTIFY=NEVER had been + specified. Problem noted by Steve Hubert of the University + of Washington, Seattle. + Add new configurable routine validate_connection (in conf.c). This + lets you decide if you are willing to accept traffic from + this host. If it returns FALSE, all SMTP commands will return + "550 Access denied". -DTCPWRAPPERS will include support for + TCP wrappers; you will need to add -lwrap to the link line. + (See src/READ_ME for details.) + Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster + bounces. Some people seemed to think that this could be + confusing (even though it is true). Suggested by Motonori + Nakamura. + Add new RunAsUser option; this causes sendmail to do a setuid to that + user early in processing to avoid potential security problems. + However, this means that all .forward and :include: files must + be readable by that user, and all files to be written must be + writable by that user and all programs will be executed by that + user. It is also incompatible with the SafeFileEnvironment + option. In other words, it may not actually add much to + security. However, it should be useful on firewalls and other + places where users don't have accounts and the aliases file is + well constrained. + Add Timeout.iconnect. This is like Timeout.connect except it is used + only on the first attempt to delivery to an address. It could + be set to be lower than Timeout.connect on the principle that + the mail should go through quickly to responsive hosts; less + responsive hosts get to wait for the next queue run. + Fix a problem on Solaris that occasionally causes programs + (such as vacation) to hang with their standard input connected + to a UDP port. It also created some signal handling problems. + The problems turned out to be an interaction between vfork(2) + and some of the libraries, particularly NIS/NIS+. I am + indebted to Tor Egge for this fix. + Change user class map to do the same matching that actual delivery + will do instead of just a /etc/passwd lookup. This adds + fuzzy matching to the user map. Patch from Dan Oscarsson. + The Timeout.* options are not safe -- they can be used to create a + denial-of-service attack. Problem noted by Christophe + Wolfhugel. + Don't send PostMasterCopy messages in the event of a "delayed" + notification. Suggested by Barry Bouwsma. + Don't advertise "VERB" ESMTP extension if the "noexpn" privacy + option is set, since this disables VERB mode. Suggested + by John Hawkinson of MIT. + Complain if the QueueDirectory (Q) option is not set. Problem noted + by Motonori Nakamura of Kyoto University. + Only queue messages on transient .forward open failures if there + were no successful opens. The previous behaviour caused it + to queue even if a "fall back" .forward was found. Problem + noted by Ann-Kian Yeo of the Dept. of Information Systems + and Computer Science (DISCS), NUS, Singapore. + Don't do 8->7 bit conversions when bouncing a MIME message that + is bouncing because of a MIME error during 8->7 bit conversion; + the encapsulated message will bounce again, causing a loop. + Problem noted by Steve Hubert of the University of Washington. + Create xf (transcript) files using the TempFileMode option value + instead of 0644. Suggested by Ann-Kian Yeo of the + National University of Singapore. + Print errors if setgid/setuid/etc. fail during delivery. This helps + detect cases where DefaultUid is set to something that the + system can't cope with. + PORTABILITY FIXES: + Support for AIX/RS 2.2.1 from Mark Whetzel of Western + Atlas International. + Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell + . + On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only + work on the first recipient of a message due to a + bug in the getpwent family.

Based on a patch from Randall + Winchester of the University of Maryland. + CONFIG: add generic-nextstep3.3.mc file. Contributed by + Robert La Ferla of Hot Software. + CONFIG: allow mailertables to resolve to ``error:code message'' + (where "code" is an exit status) on domains (previously + worked only on hosts). Patch from Cor Bosman of Xs4all + Foundation. + CONFIG: hooks for IPv6-style domain literals. + CONFIG: predefine ALIAS_FILE and change the prototype file so that + if it is undefined the AliasFile option is never set; this + should be transparent for most everyone. Suggested by John + Myers of CMU. + CONFIG: add FEATURE(limited_masquerade). Without this feature, any + domain listed in $=w is masqueraded. With it, only those + domains listed in a MASQUERADE_DOMAIN macro are masqueraded. + CONFIG: add FEATURE(masquerade_entire_domain). This causes + masquerading specified by MASQUERADE_DOMAIN to apply to all + hosts under those domains as well as the domain headers + themselves. For example, if a configuration had + MASQUERADE_DOMAIN(foo.com), then without this feature only + foo.com would be masqueraded; with it, *.foo.com would be + masqueraded as well. Based on an implementation by Richard + (Pug) Bainter of U. Texas. + CONFIG: add FEATURE(genericstable) to do a more general rewriting of + outgoing addresses. Defaults to ``hash -o /etc/genericstable''. + Keys are user names; values are outgoing mail addresses. Yes, + this does overlap with the user database, and figuring out + just when to use which one may be tricky. Based on code + contributed by Richard (Pug) Bainter of U. Texas with updates + from Per Hedeland of Ericsson. + CONFIG: add FEATURE(virtusertable) to do generalized rewriting of + incoming addresses. Defaults to ``hash -o /etc/virtusertable''. + Keys are either fully qualified addresses or just the host + part (with the @ sign). For example, a table containing: + info@foo.com foo-info + info@bar.com bar-info + @baz.org jane@elsewhere.net + would send all mail destined for info@foo.com to foo-info + (which is presumably an alias), mail addressed to info@bar.com + to bar-info, and anything addressed to anyone at baz.org will + be sent to jane@elsewhere.net. The names foo.com, bar.com, + and baz.org must all be in $=w. Based on discussions with + a great many people. + CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. + Suggested by Richard Bainter. + CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the + "fax" mailer. + CONFIG: allow mailertable entries to resolve to local:user; this + passes the original user@host in to procmail-style local + mailers as the "detail" information to allow them to do + additional clever processing. From Joe Pruett of + Teleport Corporation. Delivery to the original user can + be done by specifying "local:" (with nothing after the colon). + CONFIG: allow any context that takes "mailer:domain" to also take + "mailer:user@domain" to force mailing to the given user; + "local:user" can also be used to do local delivery. This + applies on *_RELAY and in the mailertable entries. Based + on a suggestion by Ribert Kiessling of Easynet. + CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that + limits the possible domains; this reduces the number of DNS + lookups required to support this feature. For example, + FEATURE(bestmx_is_local, my.site.com) limits the lookups + to domains under my.site.com. Code contributed by Anthony + Thyssen . + CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, + such as the check_rcpt ruleset.

Based on a suggestion + by Andreas Luik. + CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). + However, the class is not pre-initialized to contain root. + Suggested by Gregory Neil Shapiro. + CONTRIB: Remove XLA code at the request of the author, Christophe + Wolfhugel. + CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. + MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note + well: this produces a slightly different mailbox format (no + Content-Length: headers), file ownerships and modes are + different (not owned by group mail; mode 600 instead of 660), + and the local mailer flags will have to be tweaked (make them + match bsd4.4) in order to use this mailer. Patches from Paul + Hammann of the Missouri Research and Education Network. + MAIL.LOCAL: in some cases it could return EX_OK even though there + was a delivery error, such as if the ownership on the file + was wrong or the mode changed between the initial stat and + the open.

Fixes from Randy + Martin + When sendmail starts up on systems that have no fully qualified + domain name (FQDN) anywhere in the first matching host map + (e.g., /etc/hosts if the hosts service searches "files dns"), + sendmail would sleep to try to find a FQDN, which it really + really needs. This has been changed to fall through to the + next map type if it can't find a FQDN -- i.e., if the hosts + file doesn't have a FQDN, it will try dns even though the + short name was found in /etc/hosts.

The + flags can be `H' for header or `E' for envelope, + and `S' for sender or `R' for recipient. These + can be combined, so `HR' sets flags for header + recipients. + ``/canon hostname'' will try to canonify hostname and + return the result. + ``/map mapname key'' will look up `key' in the indicated + `mapname' and return the result. + Somewhat better handling of UNIX-domain socket addresses -- it + should show the pathname rather than hex bytes. + Restore ``-ba'' mode -- this reads a file from stdin and parses + the header for envelope sender information and uses + CR-LF as message terminators. It was thought to be + obsolete (used only for Arpanet NCP protocols), but it + turns out that the UK ``Grey Book'' protocols require + that functionality. + Fix a fix in previous release -- if gethostname and gethostbyname + return a name without dots, and if an attempt to canonify + that name fails, wait one minute and try again. This can + result in an extra 60 second delay on startup if your system + hostname (as returned by hostname(1)) has no dot and no names + listed in /etc/hosts or your NIS map have a dot. + Check for proper domain name on HELO and EHLO commands per + RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III + of Michigan Technological University. + Relax chownsafe rules slightly -- old version said that if you + can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, + if fpathconf returned EINVAL or ENOSYS), assume that + chown is not safe. The new version falls back to whether + you are on a BSD system or not. This is important for + SunOS, which apparently always returns one of those + error codes. This impacts whether you can mail to files + or not. + Syntax errors such as unbalanced parentheses in the configuration + file could be omitted if you had "Oem" prior to the + syntax error in the config file.

This is to handle the + ``group name: addr1, addr2, ..., addrN;'' syntax (it will + assume that ``group name:'' is a comment on the first + address and the ``;'' is a comment on the last address). + This requires config file support to get right. It does + understand that :: is NOT this syntax, and can be turned + off completely by setting the ColonOkInAddresses option. + Level 6 config files added with new mailer flags: + A Addresses are aliasable. + i Do udb rewriting on envelope as well as header + sender lines. Applies to the from address mailer + flags rather than the recipient mailer flags. + j Do udb rewriting on header recipient addresses. + Applies to the sender mailer flags rather than the + recipient mailer flags. + k Disable check for loops when doing HELO command. + o Always run as the mail recipient, even on local + delivery. + w Check for an /etc/passwd entry for this user. + 5 Pass addresses through ruleset 5. + : Check for :include: on this address. + | Check for |program on this address. + / Check for /file on this address. + @ Look up sender header addresses in the user + database. Applies to the mailer flags for the + mailer corresponding to the envelope sender + address, rather than to recipient mailer flags. + Pre-level 6 configuration files set A, w, 5, :, |, /, and @ + on the "local" mailer, the o flag on the "prog" and "*file*" + mailers, and the ColonOkInAddresses option. + Eight-to-seven bit MIME conversions. This borrows ideas from + John Beck of Hewlett-Packard, who generously contributed + their implementation to me, which I then didn't use (see + mime.c for an explanation of why). This adds the + EightBitMode option (a.k.a. `8') and an F=8 mailer flag + to control handling of 8-bit data. These have to cope with + two types of 8-bit data: unlabelled 8-bit data (that is, + 8-bit data that is entered without declaring it as 8-bit + MIME -- technically this is illegal according to the + specs) and labelled 8-bit data (that is, it was declared + as 8BITMIME in the ESMTP session or by using the + -B8BITMIME command line flag). If the F=8 mailer flag is + set then 8-bit data is sent to non-8BITMIME machines + instead of converting to 7 bit (essentially using + just-send-8 semantics). The values for EightBitMode are: + m convert unlabelled 8-bit input to 8BITMIME, and do + any necessary conversion of 8BITMIME to 7BIT + (essentially, the full MIME option). + p pass unlabelled 8-bit input, but convert labelled + 8BITMIME input to 7BIT as required (default). + s strict adherence: reject unlabelled 8-bit input, + convert 8BITMIME to 7BIT as required. The F=8 + flag is ignored. + Unlabelled 8-bit data is rejected in mode `s' regardless of + the setting of F=8. + Add new internal class 'n', which is the set of MIME Content-Types + which can not be 8 to 7 bit encoded because of other + considerations. Types "multipart/*" and "message/*" are + never directly encoded (although their components can be). + Add new internal class 's', which is the set of subtypes of the + MIME message/* content type that can be treated as though + they are an RFC822 message. It is predefined to have + "rfc822". Suggested By Kari Hurtta. + Add new internal class 'e'. This is the set of MIME + Content-Transfer-Encodings that can be converted to + a seven bit format (Quoted-Printable or Base64). It is + preinitialized to contain "7bit", "8bit", and "binary". + Add C=charset mailer parameter and the the DefaultCharSet option (no + short name) to set the default character set to use in the + Content-Type: header when doing encoding of an 8-bit message + which isn't marked as MIME into MIME format. If the C= + parameter is set on the Envelope From address, use that as + the default encoding; else use the DefaultCharSet option. + If neither is set, it defaults to "unknown-8bit" as + suggested by RFC 1428 section 3. + Allow ``U=user:group'' field in mailer definition to set a default + user and group that a mailer will be executed as. This + overrides the 'u' and 'g' options, and if the `F=S' flag is + also set, it is the uid/gid that will always be used (that + is, the controlling address is ignored). The values may be + numeric or symbolic; if only a symbolic user is given (no + group) that user's default group in the passwd file is used + as the group. Based on code donated by Chip Rosenthal of + Unicom. + Allow `u' option to also accept user:group as a value, in the same + fashion as the U= mailer option. + Add the symbolic time zone name in the Arpanet format dates (as + a comment). This adds a new compile-time configuration + flag: TZ_TYPE can be set to TZ_TM_NAME (use the value + of (struct tm *)->tm_name), TZ_TM_ZONE (use the value + of (struct tm *)->tm_zone), TZ_TZNAME (use extern char + *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use + timezone()), or TZ_NONE (don't include the comment). Code + from Chip Rosenthal. + The "Timeout" option (formerly "r") is extended to allow suboptions. + For example, + O Timeout.helo = 2m + There are also two new suboptions "queuereturn" and + "queuewarn"; these subsume the old T option. Thus, to + set them both the preferred new syntax is + O Timeout.queuereturn = 5d + O Timeout.queuewarn = 4h + Sort queue by host name instead of by message priority if the + QueueSortOrder option (no short name) is set is set to + ``host''. This makes better use of the connection cache, + but may delay more ``interactive'' messages behind large + backlogs under some circumstances. This is probably a + good option if you have high speed links or don't do lots + of ``batch'' messages, but less good if you are using + something like PPP on a 14.4 modem. Based on code + contributed by Roy Mongiovi of Georgia Tech (my main + contribution was to make it configurable). + Save i-number of df file in qf file to simplify rebuilding of queue + after disastrous disk crash. Suggested by Kyle Jones of + UUNET; closely based on code from KJS DECWRL code written + by Paul Vixie. NOTA BENE: The qf files produced by 8.7 + are NOT back compatible with 8.6 -- that is, you can convert + from 8.6 to 8.7, but not the other direction. + Add ``F=d'' mailer flag to disable all use of angle brackets in + route-addrs in envelopes; this is because in some cases + they can be sent to the shell, which interprets them as + I/O redirection. + Don't include error file (option E) with return-receipts; this + can be confusing. + Don't send "Warning: cannot send" messages to owner-* or + *-request addresses. Suggested by Christophe Wolfhugel + of the Institut Pasteur, Paris. + Allow -O command line flag to set long form options. + Add "MinQueueAge" option to set the minimum time between attempts + to run the queue. For example, if the queue interval + (-q value) is five minutes, but the minimum queue age + is fifteen minutes, jobs won't be tried more often than + once every fifteen minutes. This can be used to give + you more responsiveness if your delivery mode is set to + queue-only. + Allow "fileopen" timeout (default: 60 seconds) for opening + :include: and .forward files. + Add "-k", "-v", and "-z" flags to map definitions; these set the + key field name, the value field name, and the field + delimiter. The field delimiter can be a single character + or the sequence "\t" or "\n" for tab or newline. + These are for use by NIS+ and similar access methods. + Change maps to always strip quotes before lookups; the -q flag + turns off this behaviour. Suggested by Motonori Nakamura. + Add "nisplus" map class. Takes -k and -v flags to choose the + key and value field names respectively. Code donated by + Sun Microsystems. + Add "hesiod" map class. The "file name" is used as the + "HesiodNameType" parameter to hes_resolve(3). Returns the + first value found for the match. Code donated by Scott + Hutton of Indiana University. + Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to + specify the name of the property that is searched as the + key and a -v flag to specify the name of the property that + is returned as the value (defaults to "members"). The + default map is "/aliases". Some code based on code + contributed by Robert La Ferla of Hot Software. + Add "text" map class. This does slow, linear searches through + text files. The -z flag specifies a column delimiter + (defaults to any sequence of white space), the -k flag + sets the key column number, and the -v flag sets the + value column number. Lines beginning with `#' are treated + as comments. + Add "program" map class to execute arbitrary programs. The search + key is presented as the last argument; the output is one + line read from the programs standard output. Exit statuses + are from sysexits.h. + Add "sequence" map class -- searches maps in sequence until it + finds a match. For example, the declarations: + Kmap1 ... + Kmap2 ... + Kmapseq sequence map1 map2 + defines a map "mapseq" that first searches map1; if the + value is found it is returned immediately, otherwise + map2 is searched and the value returned. + Add "switch" map class. This is much like "sequence" except that + the ordering is fetched from an external file, usually + the system service switch. The parameter is the name of + the service to switch on, and the maps that it will use + are the name of the switch map followed by ".service_type". + For example, if the declaration of the map is + Ksample switch hosts + and the system service switch specifies that hosts are + looked up using dns and nis in that order, then this is + equivalent to + Ksample sequence sample.dns sample.nis + The subordinate maps (sample.*) must already be defined. + Add "user" map class -- looks up users using getpwnam. Takes a + "-v field" flag on the definition that tells what passwd + entry to return -- legal values are name, passwd, uid, gid, + gecos, dir, and shell. Generally expected to be used with + the -m (matchonly) flag. + Add "bestmx" map class -- returns the best MX value for the host + listed as the value. If there are several "best" MX records + for this host, one will be chosen at random. + Add "userdb" map class -- looks up entries in the user database. + The "file name" is actually the tag that will be used, + typically "mailname". If there are multiple entries + matching the name, the one chosen is undefined. + Add multiple queue timeouts (both return and warning). These are + set by the Precedence: or Priority: header fields to one of + three values. If a Priority: is set and has value "normal", + "urgent", or "non-urgent" the corresponding timeouts are + used. If no priority is set, the Precedence: is consulted; + if negative, non-urgent timeouts are used; if greater than + zero, urgent timeouts are used. Otherwise, normal timeouts + are used. The timeouts are set by setting the six timeouts + queue{warn,return}.{urgent,normal,non-urgent}. + Fix problem when a mail address is resolved to a $#error mailer + with a temporary failure indication; it works in SMTP, + but when delivering locally the mail is silently discarded. + This patch, from Kyle Jones of UUNET, bounces it instead + of queueing it (queueing is very hard). + When using /etc/hosts or NIS-style lookups, don't assume that + the first name in the list is the best one -- instead, + search for the first one with a dot. For example, if + an /etc/hosts entry reads + 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU + this change will use the second name as the canonical + machine name instead of the initial, unqualified name. + Change dequote map to replace spaces in quoted text with a value + indicated by the -s flag on the dequote map definition. + For example, ``Mdequote dequote -s_'' will change + "Foo Bar" into an unquoted Foo_Bar instead of leaving it + quoted (because of the space character). Suggested by Dan + Oscarsson for use in X.400 addresses. + Implement long macro names as ${name}; long class names can + be similarly referenced as $={name} and $~{name}. + Definitions are (e.g.) ``D{name}value''. Names that have + a leading lower case letter or punctuation characters are + reserved for internal use by sendmail; i.e., config files + should use names that begin with a capital letter. Based + on code contributed by Dan Oscarsson. + Fix core dump if getgrgid returns a null group list (as opposed + to an empty group list, that is, a pointer to a list + with no members). Fix from Andrew Chang of Sun Microsystems. + Fix possible core dump if malloc fails -- if the malloc in xalloc + failed, it called syserr which called newstr which called + xalloc.... The newstr is now avoided for "panic" messages. + Reported by Stuart Kemp of James Cook University. + Improve connection cache timeouts; previously, they were not even + checked if you were delivering to anything other than an + IPC-connected host, so a series of (say) local mail + deliveries could cause cached connections to be open + much longer than the specified timeout. + If an incoming message exceeds the maximum message size, stop + writing the incoming bytes to the queue data file, since + this can fill your mqueue partition -- this is a possible + denial-of-service attack. + Don't reject all numeric local user names unless HESIOD is + defined. It turns out that Posix allows all-numeric + user names. Fix from Tony Sanders of BSDI. + Add service switch support. If the local OS has a service + switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf + on DEC systems) that will be used; otherwise, it falls back + to using a local mechanism based on the ServiceSwitchFile + option (default: /etc/service.switch). For example, if the + service switch lists "files" and "nis" for the aliases + service, that will be the default lookup order. the "files" + ("local" on DEC) service type expands to any alias files + you listed in the configuration file, even if they aren't + actually file lookups. + Option I (NameServerOptions) no longer sets the "UseNameServer" + variable which tells whether or not DNS should be considered + canonical. This is now determined based on whether or not + "dns" is in the service list for "hosts". + Add preliminary support for the ESMTP "DSN" extension (Delivery + Status Notifications). DSN notifications override + Return-Receipt-To: headers, which are bogus anyhow -- + support for them has been removed. + Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer + definitions to define the types used in DSN returns for + MTA names, addresses, and diagnostics respectively. + Extend heuristic to force running in ESMTP mode to look for the + five-character string "ESMTP" anywhere in the 220 greeting + message (not just the second line). This is to provide + better compatibility with other ESMTP servers. + Print sequence number of job when running the queue so you can + easily see how much progress you have made. Suggested + by Peter Wemm of DIALix. + Map newlines to spaces in logged message-ids; some versions of + syslog truncate the rest of the line after newlines. + Suggested by Fletcher Mattox of U. Texas. + Move up forking for job runs so that if a message is split into + multiple envelopes you don't get "fork storms" -- this + also improves the connection cache utilization. + Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for + the purposes of refusing to send error returns. Suggested + by Motonori Nakamura of Ritsumeikan University. + Relax rules on when a file can be written when referenced from + the aliases file: use the default uid/gid instead of the + real uid/gid. This allows you to create a file owned by + and writable only by the default uid/gid that will work + all the time (without having the setuid bit set). Change + suggested by Shau-Ping Lo and Andrew Cheng of Sun + Microsystems. + Add "DialDelay" option (no short name) to provide an "extra" + delay for dial on demand systems. If this is non-zero + and a connect fails, sendmail will wait this long and + then try again. If it takes longer than the kernel + timeout interval to establish the connection, this + option can give the network software time to establish + the link. The default units are seconds. + Move logging of sender information to be as early as possible; + previously, it could be delayed a while for SMTP mail + sent to aliases. Suggested by Brad Knowles of the + Defense Information Systems Agency. + Call res_init() before setting RES_DEBUG; this is required by + BIND 4.9.3, or so I'm told. From Douglas Anderson of + the National Computer Security Center. + Add xdelay= field in logs -- this is a transaction delay, telling + you how long it took to deliver to this address on the + last try. It is intended to be used for sorting mailing + lists to favor "quick" addresses. Provided for use by + the mailprio scripts (see below). + If a map cannot be opened, and that map is non-optional, and + an address requires that map for resolution, queue the + map instead of bouncing it. This involves creating a + pseudo-class of maps called "bogus-map" -- if a required + map cannot be opened, the class is changed to bogus-map; + all queries against bogus-map return "tempfail". The + bogus-map class is not directly accessible. A sample + implementation was donated by Jem Taylor of Glasgow + University Computing Service. + Fix a possible core dump when mailing to a program that talks + SMTP on its standard input. Fix from Keith Moore of + the University of Kentucky. + Make it possible to resolve filenames to $#local $: @ /filename; + previously, the "@" would cause it to not be recognized + as a file. Problem noted by Brian Hill of U.C. Davis. + Accept a -1 signal to re-exec the daemon. This only works if + argv[0] is a full path to sendmail. + Fix bug in "addr=..." field in O option on little-endian machines + -- the network number wasn't being converted to network + byte order. Patch from Kurt Lidl of Pix Technologies + Corporation. + Pre-initialize the resolver early on; this is to avoid a bug with + BIND 4.9.3 that can cause the _res.retry field to get + reset to zero, causing all name server lookups to time + out. Fix from Matt Day of Artisoft. + Restore T line (trusted users) in config file -- but instead of + locking out the -f flag, they just tell whether or not + an X-Authentication-Warning: will be added. This really + just creates new entries in class 't', so "Ft/file/name" + can be used to read trusted user names from a file. + Trusted users are also allowed to execute programs even + if they have a shell that isn't in /etc/shells. + Improve NEWDB alias file rebuilding so it will create them + properly if they do not already exist. This had been + a MAYBENEXTRELEASE feature in 8.6.9. + Check for @:@ entry in NIS maps before starting up to avoid + (but not prevent, sigh) race conditions. This ought to + be handled properly in ypserv, but isn't. Suggested by + Michael Beirne of Motorola. + Refuse connections if there isn't enough space on the filesystem + holding the queue. Contributed by Robert Dana of Wolf + Communications. + Skip checking for directory permissions in the path to a file + when checking for file permissions iff setreuid() + succeeded -- it is unnecessary in that case. This avoids + significant performance problems when looking for .forward + files. Based on a suggestion by Win Bent of USC. + Allow symbolic ruleset names. Syntax can be "Sname" to get an + arbitrary ruleset number assigned or "Sname = integer" + to assign a specific ruleset number. Reference is + $>name_or_number. Names can be composed of alphas, digits, + underscore, or hyphen (first character must be non-numeric). + Allow -o flag on AliasFile lines to make the alias file optional. + From Bryan Costales of ICSI. + Add NoRecipientAction option to handle the case where there is + no legal recipient header in the message. It can take + on values: + None Leave the message as is. The + message will be passed on even + though it is in technically + illegal syntax. + Add-To Add a To: header with any + recipients that it can find from + the envelope. This risks exposing + Bcc: recipients. + Add-Apparently-To Add an Apparently-To: header. This + has almost no redeeming social value, + and is provided only for back + compatibility. + Add-To-Undisclosed Add a header reading + To: undisclosed-recipients:; + which will have the effect of + making the message legal without + exposing Bcc: recipients. + Add-Bcc To add an empty Bcc: header. + There is a chance that mailers down + the line will delete this header, + which could cause exposure of Bcc: + recipients. + The default is NoRecipientAction=None. + Truncate (rather than delete) Bcc: lines in the header. This + should prevent later sendmails (at least, those that don't + themselves delete Bcc:) from considering this message to + be non-conforming -- although it does imply that non-blind + recipients can see that a Bcc: was sent, albeit not to whom. + Add SafeFileEnvironment option. If declared, files named as delivery + targets must be regular files in addition to the regular + checks. Also, if the option is non-null then it is used as + the name of a directory that is used as a chroot(2) + environment for the delivery; the file names listed in an + alias or forward should include the name of this root. + For example, if you run with + O SafeFileEnvironment=/arch + then aliases should reference "/arch/rest/of/path". If a + value is given, sendmail also won't try to save to + /usr/tmp/dead.letter (instead it just leaves the job in the + queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. + Support -A flag for alias files; this will comma concatenate like + entries. For example, given the aliases: + list: member1 + list: member2 + and an alias file declared as: + OAhash:-A /etc/aliases + the final alias inserted will be "list: member1,member2"; + without -A you will get an error on the second and subsequent + alias for "list". Contributed by Bryan Costales of ICSI. + Line-buffer transcript file. Suggested by Liudvikas Bukys. + Fix a problem that could cause very long addresses to core dump in + some special circumstances. Problem pointed out by Allan + Johannesen. + (Internal change.) Change interface to expand() (macro expansion) + to be simpler and more consistent. + Delete check for funny qf file names. This didn't really give + any extra security and caused some people some problems. + (If you -really- want this, define PICKY_QF_NAME_CHECK + at compile time.) Suggested by Kyle Jones of UUNET. + (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and + merge with DSN code; this is simpler and more consistent. + This may affect some people who have written their own + checkcompat() routine. + (Internal change.) Eliminate `D' line in qf file. The df file + is now assumed to be the same name as the qf file (with + the `q' changed to a `d', of course). + Avoid forking for delivery if all recipient mailers are marked as + "expensive" -- this can be a major cost on some systems. + Essentially, this forces sendmail into "queue only" mode + if all it is going to do is queue anyway. + Avoid sending a null message in some rather unusual circumstances + (specifically, the RCPT command returns a temporary + failure but the connection is lost before the DATA + command). Fix from Scott Hammond of Secure Computing + Corporation. + Change makesendmail to use a somewhat more rational naming scheme: + Makefiles and obj directories are named $os.$rel.$arch, + where $os is the operating system (e.g., SunOS), $rel is + the release number (e.g., 5.3), and $arch is the machine + architecture (e.g., sun4). Any of these can be omitted, + and anything after the first dot in a release number can + be replaced with "x" (e.g., SunOS.4.x.sun4). The previous + version used $os.$arch.$rel and was rather less general. + Change makesendmail to do a "make depend" in the target directory + when it is being created. This involves adding an empty + "depend:" entry in most Makefiles. + Ignore IDENT return value if the OSTYPE field returns "OTHER", + as indicated by RFC 1413. Pointed out by Kari Hurtta + of the Finnish Meteorological Institute. + Fix problem that could cause multiple responses to DATA command + on header syntax errors (e.g., lines beginning with colons). + Problem noted by Jens Thomassen of the University of Oslo. + Don't let null bytes in headers cause truncation of the rest of + the header. + Log Authentication-Warning:s. Suggested by Motonori Nakamura. + Increase timeouts on message data puts to allow time for receivers + to canonify addresses in headers on the fly. This is still + a rather ugly heuristic. From Motonori Nakamura. + Add "HasWildcardMX" suboption to ResolverOptions; if set, MX + records are not used when canonifying names, and when MX + lookups are done for addressing they must be fully + qualified. This is useful if you have a wildcard MX record, + although it may cause other problems. In general, don't use + wildcard MX records. Patch from Motonori Nakamura. + Eliminate default two-line SMTP greeting message. Instead of + adding an extra "ESMTP spoken here" line, the word "ESMTP" + is added between the first and second word of the first + line of the greeting message (i.e., immediately after the + host name). This eliminates the need for the BROKEN_SMTP_PEERS + compile flag. Old sendmails won't see the ESMTP, but that's + acceptable because SIZE was the only useful extension that + old sendmails understand. + Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 + invoked state dumps. From Masaharu Onishi. + Allow on-line comments in .forward and :include: files; they are + introduced by the string "#@#", where + is a space or a tab. This is intended for native + representation of non-ASCII sets such as Japanese, where + existing encodings would be unreadable or would lose + data -- for example, + NAKAMURA Motonori + (romanized/less information) + =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= + =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= + (with MIME encoding, not human readable) + #@# ^[$BCfB<^[(B ^[$BAGE5^[(B + (native encoding with ISO-2022-JP) + The last form is human readable in the Japanese environment. + Based on a fix from (surprise!) Motonori Nakamura. + Don't make SMTP error returns on MAIL FROM: line be "sticky" for all + messages to that host; these are most frequently associated + with addresses rather than the host, with the exception of + 421 (service shutting down). The effect was to cause queues + to sometimes take an excessive time to flush. Reported by + Robert Sargent of Southern Geographics Technologies and + Eric Prestemon of American University. + Add Nice=N mailer option to set the niceness at which a mailer will + run. This is actually a relative niceness (that is, an + increment on the background value). + Log queue runs that are skipped due to high loads. They are logged + at LOG_INFO priority iff the log level is > 8. Contributed + by Bruce Nagel of Data General. + Allow the error mailer to accept a DSN-style error status code + instead of an sysexits status code in the host part. + Anything with a dot will be interpreted as a DSN-style code. + Add new mailer flag: F=3 will tell translations to Quoted-Printable + to encode characters that might be munged by an EBCDIC system + in addition to the set required by RFC 1521. The additional + characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. + (Think of "IBM 360" as the mnemonic for this flag.) + Change check for mailing to files to look for a pathname of [FILE] + rather than looking for the mailer named *file*. The mapping + of leading slashes still goes to the *file* mailer. This + allows you to implement the *file* mailer as a separate + program, for example, to insert a Content-Length: header + or do special security policy. However, note that the usual + initial checking for the file permissions is still done, and + the program in question needs to be very careful about how + it does the file write to avoid security problems. + Be able to read ~root/.forward even if the path isn't accessible to + regular users. This is disrecommended because sendmail + sometimes does not run as root (e.g., when an unsafe option + is specified on the command line), but should otherwise be + safe because .forward files must be owned by the user for + whom mail is being forwarded, and cannot be a symbolic link. + Suggested by Forrest Aldrich of Wang Laboratories. + Add new "HostsFile" option that is the pathname to the /etc/hosts + file. This is used for canonifying hostnames when the + service type is "files". + Implement programs on F (read class from file) line. The syntax is + Fc|/path/to/program to read the output from the program + into class "c". + Probe the network interfaces to find alternate names for this + host. Requires the SIOCGIFCONF ioctl call. Code + contributed by SunSoft. + Add "E" configuration line to set or propagate environment + variables into children. "E" will propagate + the named variable from the environment when sendmail + was invoked into any children it calls; "E=" + sets the named variable to the indicated value. Any + variables not explicitly named will not be in the child + environment. However, sendmail still forces an + "AGENT=sendmail" environment variable, in part to enforce + at least one environment variable, since many programs and + libraries die horribly if this is not guaranteed. + Change heuristic for rebuilding both NEWDB and NDBM versions of + alias databases -- new algorithm looks for the substring + "/yp/" in the file name. This is more portable and involves + less overhead. Suggested by Motonori Nakamura. + Dynamically allocate the queue work list so that you don't lose + jobs in large queue runs. The old QUEUESIZE compile parameter + is replaced by QUEUESEGSIZE (the unit of allocation, which + should not need to be changed) and the MaxQueueRunSize option, + which is the absolute maximum number of jobs that will ever + be handled in a single queue run. Based on code contributed + by Brian Coan of the Institute for Global Communications. + Log message when a message is dropped because it exceeds the maximum + message size. Suggested by Leo Bicknell of Virginia Tech. + Allow trusted users (those on a T line or in $=t) to use -bs without + an X-Authentication-Warning: added. Suggested by Mark Thomas + of Mark G. Thomas Consulting. + Announce state of compile flags on -d0.1 (-d0.10 throws in the + OS-dependent defines). The old semantic of -d0.1 to not + run the daemon in background has been moved to -d99.100, + and the old 52.5 flag (to avoid disconnect() from closing + all output files) has been moved to 52.100. This makes + things more consistent (flags below .100 don't change + semantics) and separates out the backgrounding so that + it doesn't happen automatically on other unrelated debugging + flags. + If -t is used but no addresses are found in the header, give an + error message rather than just doing nothing. Fix from + Motonori Nakamura. + On systems (like SunOS) where the effective gid is not necessarily + included in the group list returned by getgroups(), the + `restrictmailq' option could sometimes cause an authorized + user to not be able to use `mailq'. Fix from Charles Hannum + of MIT. + Allow symbolic service names for [IPC] mailers. Suggested by + Gerry Magennis of Logica International. + Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs + when running DNS. For example, if the name FTP.Foo.ORG is + a CNAME for Cruft.Foo.ORG, then when sitting on a machine in + the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" + if this option is not set, or "FTP.Foo.ORG" if it is set. + This is technically illegal under RFC 822 and 1123, but the + IETF is moving toward legalizing it. Note that turning on + this option is not sufficient to guarantee that a downstream + neighbor won't rewrite the address for you. + Add "-m" flag to makesendmail script -- this tells you what object + directory and Makefile it will use, but doesn't actually do + the make. + Do some additional checking on the contents of the qf file to try + to detect attacks against the qf file. In particular, + abort on any line beginning "From ", and add an "end of + file" line -- any data after that line is prohibited. + Always use /etc/sendmail.cf, regardless of the arbitrary vendor + choices. This can be overridden in the Makefile by using + either -DUSE_VENDOR_CF_PATH to get the vendor location + (to the extent that we know it) or by defining + _PATH_SENDMAILCF (which is a "hard override"). This allows + sendmail 8 to have more consistent installation instructions. + Allow macros on `K' line in config file. Suggested by Andrew Chang + of Sun Microsystems. + Improved symbol table hash function from Eric Wassenaar. This one + is at least 50% faster. + Fix problem that didn't notice that timeout on file open was a + transient error. Fix from Larry Parmelee of Cornell + University. + Allow comments (lines beginning with a `#') in files read for + classes. Suggested by Motonori Nakamura. + Make SIGINT (usually ^C) in test mode return to the prompt instead + of dropping out entirely. This makes testing some of the + name server lookups easier to deal with when there are + hung servers. From Motonori Nakamura. + Add new ${opMode} macro that is set to the current operation mode + (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by + Claude Marinier . + Add new delivery mode (Odd) that defers all map lookups to queue runs. + Kind of like queue-only mode (Odq) except it tries to avoid + any external service requests; for dial-on-demand hosts that + want to minimize DNS lookups when mail is being queued. For + this to work you will also have to make sure that gethostbyname + of your local host name does not do a DNS lookup. + Improved handling of "out of space" conditions from John Myers of + Carnegie Mellon. + Improved security for mailing to files on systems that have fchmod(2) + support. + Improve "cannot send message for N days" message -- now says "could + not send for past N days". Suggested by Tom Moore of AT&T + Global Information Solutions. + Less misleading Subject: line on messages sent to postmaster only. + From Motonori Nakamura. + Avoid duplicate error messages on bad command line flags. From + Motonori Nakamura. + Better error message for case where ruleset 0 falls off the end + or otherwise does not resolve to a canonical triple. + Fix a problem that could cause multiple bounce messages if a bad + address was sent along with a good address to an SMTP + site where that SMTP site returned a 4yz code in response + to the final dot of the data. Problem reported by David + James of British Telecom. + Add "volatile" declarations so that gcc -O2 will work. Patches + from Alexander Dupuy of System Management ARTS. + Delete duplicates in MX lists -- believe it or not, there are sites + that list the same host twice in an MX list. This deletion + only works on adjacent preferences, so an MX list that + had A=5, B=10, A=15 would leave both As, but one that had + A=5, A=10, B=15 would reduce to A, B. This is intentional, + just in case there is something weird I haven't thought of. + Suggested by Barry Shein of Software Tool & Die. + SECURITY: .forward files cannot be symbolic links.

Problem noted by John Gardiner Myers of CMU. + CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. + From Paul Riddle of the University of Maryland, Baltimore + County. + CONFIG: Catch and reject "." as a host address. + CONFIG: Generalize domaintable to look up all domains, not + just unqualified ones. + CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it + was never used and didn't work anyway. + CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer + and d on all mailers in the UUCP class. + CONFIG: Allow "user+detail" to be aliased specially: it will first + look for an alias for "user+detail", then for "user+*", and + finally for "user". This is intended for forwarding mail + for system aliases such as root and postmaster to a + centralized hub. + CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). + CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. + The F=8 flag is also set on the "relay" mailer, since + this is expected to be another sendmail. + CONFIG: avoid qualifying all UUCP addresses sent via SMTP with + the name of the UUCP_RELAY -- in some cases, this is the + wrong value (e.g., when we have local UUCP connections), + and this can create unreplyable addresses. From Chip + Rosenthal of Unicom. + CONFIG: add confRECEIVED_HEADER to change the format of the + Received: header inserted into all messages. Suggested by + Gary Mills of the University of Manitoba. + CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) + to get the old behaviour. I did this upon observing + that almost everyone needed this feature, and that the + concept I was trying to make happen didn't work with + some user agents anyway. FEATURE(notsticky) still works, + but it is a no-op. + CONFIG: Add LUSER_RELAY -- the host to which unrecognized user + names are sent, rather than immediately diagnosing them + as User Unknown. + CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, + and RELAY_MAILER_ARGS to set the arguments for the + indicated mailers. All default to "IPC $h". Patch from + Larry Parmelee of Cornell University. + CONFIG: pop mailer needs F=n flag to avoid "annoying side effects + on the client side" and F=P to get an appropriate + return-path. From Kimmo Suominen. + CONFIG: add FEATURE(local_procmail) to use the procmail program + as the local mailer. For addresses of the form "user+detail" + the "detail" part is passed to procmail via the -a flag. + Contributed by Kimmo Suominen. + CONFIG: add MAILER(procmail) to add an interface to procmail for + use from mailertables. This lets you execute arbitrary + procmail scripts. Contributed by Kimmo Suominen. + CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. + CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From + Paul Southworth of CICNet Systems Support. + CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. + This causes the null return path to be rewritten as + MAILER-DAEMON; otherwise UUCP gets horribly confused. + From Michael Hohmuth of Technische Universitat Dresden. + CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that + list us as the best possible MX record to be treated as + though they were local (essentially, assume that they + are included in $=w). This can cause additional DNS + traffic, but is easier to administer if this fits your + local model. It does not work reliably if there are + multiple hosts that share the best MX preference. + Code contributed by John Oleynick of Rutgers. + CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted + SHell) instead of /bin/sh as the program used for delivery + to programs. If an argument is included, it is used as + the path to smrsh; otherwise, /usr/local/etc/smrsh is + assumed. + CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the + size of messages to the local and procmail mailers + respectively. Contributed by Brad Knowles of the Defense + Information Systems Agency. + CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments + (just like text outside of angle brackets) in order to + properly deal with ``group: addr1, ... addrN;'' syntax. + CONFIG: Require OSTYPE macro (the defaults really don't apply to + any real systems any more) and tweak the DOMAIN macro + so that it is less likely that users will accidentally use + the Berkeley defaults. Also, create some generic files + that really can be used in the real world. + CONFIG: Add new configuration macros to set character sets for + messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, + SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. + CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. + The old name will still be accepted for a while at least. + CONFIG: Implement DECNET_RELAY as spec for host to which DECNET + mail (.DECNET pseudo-domain or node::user) will be sent. + As with all relays, it can be ``mailer:hostname''. Suggested + by Scott Hutton. + CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed + by Barb Dijker of Labyrinth Computer Services. + CONFIG: change confCHECK_ALIASES to default to False -- it has poor + performance for large alias files, and this confused many + people. + CONFIG: Add confCF_VERSION to append local information to the + configuration version number displayed during SMTP startup. + CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it + would only work when locally addressed. Fix from + Edvard Tuinder of Cistron Internet Services. + CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option + "n" (CheckAlaises) is set when rebuilding alias database. + Based on code contributed by Claude Marinier. + CONFIG: Allow mailertable to have values of the form + ``error:code message''. The ``code'' is a status code + derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. + Contributed by David James . + CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of + sender domains that will be replaced with the masquerade name. + These domains will not be treated as local, but if mail passes + through with sender addresses in those domains they will be + replaced by the masquerade name. These can also be specified + in a file using MASQUERADE_DOMAIN_FILE(filename). + CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope + as well as the header. Substantial improvements to this + code were contributed by Per Hedeland. + CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be + accessed from a mailertable to do CCSO ph lookups. Contributed + by Kimmo Suominen. + CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be + used to define cyrus and cyrusbb mailers (for IMAP support). + Contributed by John Gardiner Myers of Carnegie Mellon. + CONFIG: add confUUCP_MAILER to select default mailer to use for + UUCP addressing.

Based on code contributed by + Todd Miller (this problem was also reported by Guy Helmer + of Dakota State University). This also fixes a related + problem reported by Liudvikas Bukys of the University of + Rochester. + Parameterize "nroff -h" in all the Makefiles so people with + variant versions can use them easily. Suggested by + Peter Collinson of Hillside Systems. + SMTP "MAIL" commands with multiple ESMTP parameters required two + spaces between parameters instead of one. Reported by + Valdis Kletnieks of Virginia Tech. + Reduce the number of system calls during message collection by + using global timeouts around the collect() loop. This + code was contributed by Eric Wassenaar. + If the initial hostname name gathering results in a name + without a dot (usually caused by NIS misconfiguration) + and BIND is compiled in, directly access DNS to get + the canonical name. This should make life easier for + Solaris systems. If it still can't be resolved, and + if the name server is listed as "required", try again + in 30 seconds. If that also fails, exit immediately to + avoid bogus "config error: mail loops back to myself" + messages. + Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error + message to explain how much space was available and + sound a bit less threatening. Suggested by Stan Janet + of the National Institute of Standards and Technology. + If mail is delivered to an alias that has an owner, deliver any + requested return-receipt immediately, and strip the + Return-Receipt-To: header from the subsequent message. + This prevents a certain class of denial of service + attack, arguably gives more reasonable semantics, and + moves things more towards what will probably become a + network standard. Suggested by Christopher Davis of + Kapor Enterprises. + Add a "noreceipts" privacy flag to turn off all return receipts + without recompiling. + Avoid printing ESMTP parameters as part of the error message + if there are errors during parsing. This change is + purely cosmetic. + Avoid sending out error messages during the collect phase of + SMTP; there is an MVS mailer from UCLA that gets + confused by this. Of course, I think it's their bug.... + Check for the $j macro getting undefined, losing a dot, or getting + lost from $=w in the daemon before accepting a connection; + if it is, it dumps state, prints a LOG_ALERT message, + and drops core for debugging. This is an attempt to + track down a bug that I thought was long since gone. + If you see this, please forward the log fragment to + sendmail@sendmail.ORG. + Change OLD_NEWDB from a #ifdef to a #if so it can be turned off + with -DOLD_NEWDB=0 on the command line. From Christophe + Wolfhugel. + Instead of trying to truncate the listen queue for the server + SMTP port when the load average is too high, just close + the port completely and reopen it later as needed. + This ensures that the other end gets a quick "connection + refused" response, and that the connection can be + recovered later. In particular, some socket emulations + seem to get confused if you tweak the listen queue + size around and can never start listening to connections + again. The down side is that someone could start up + another daemon process in the interim, so you could + have multiple daemons all not listening to connections; + this could in turn cause the sendmail.pid file to be + incorrect. A better approach might be to accept the + connection and give a 421 code, but that could break + other mailers in mysterious ways and have paging behaviour + implications. + Fix a glitch in TCP-level debugging that caused flag 16.101 to + set debugging on the wrong socket. From Eric Wassenaar. + When creating a df* temporary file, be sure you truncate any + existing data in the file -- otherwise system crashes + and the like could result in extra data being sent. + DOC: Replace the CHANGES-R5-R8 readme file with a paper in the + doc directory. This includes some additional + information. + CONFIG: change UUCP rules to never add $U! or $k! on the front + of recipient envelope addresses. This should have been + handled by the $&h trick, but broke if people were + mixing domainized and UUCP addresses. They should + probably have converted all the way over to uucp-uudom + instead of uucp-{new,old}, but the failure mode was to + loop the mail, which was bad news. + Portability fixes: + Newer BSDI systems (several people). + Older BSDI systems from Christophe Wolfhugel. + Intergraph CLIX, from Paul Southworth of CICNet. + UnixWare, from Evan Champion. + NetBSD from Adam Glass. + Solaris from Quentin Campbell of the University of + Newcastle upon Tyne. + IRIX from Dean Cookson and Bill Driscoll of Mitre + Corporation. + NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. + SunOS (it has setsid() and setvbuf() calls) from + Jonathan Kamens of OpenVision Technologies. + HP-UX from Tor Lillqvist. + New Files: + src/Makefile.CLIX + src/Makefile.NCR3000 + doc/changes/Makefile + doc/changes/changes.me + doc/changes/changes.ps + +8.6.8/8.6.6 94/03/21 + SECURITY: it was possible to read any file as root using the + E (error message) option.

Thanks to Alain Durand of + INRIA for forwarding me the notice from the bugtraq + list. + +8.6.6/8.6.6 94/03/13 + SECURITY: the ability to give files away on System V-based + systems proved dangerous -- don't run as the owner + of a :include: file on a system that allows giveaways. + Unfortunately, this also applies to determining a + valid shell. + IMPORTANT: Previous versions weren't expiring old connections + in the connection cache for a long time under some + circumstances. This could result in resource exhaustion, + both at your end and at the other end. This checks the + connections for timeouts much more frequently. From + Doug Anderson of NCSC. + Fix a glitch that snuck in that caused programs to be run as + the sender instead of the recipient if the mail was + from a local user to another local user. From + Motonori Nakamura of Kyoto University. + Fix "wildcard" on /etc/shells matching -- instead of looking + for "*", look for "/SENDMAIL/ANY/SHELL/". From + Bryan Costales of ICSI. + Change the method used to declare the "statfs" availability; + instead of HASSTATFS and/or HASUSTAT with a ton of + tweaking in conf.c, there is a single #define called + SFS_TYPE which takes on one of six values (SFS_NONE + for no statfs availability, SFS_USTAT for the ustat(2) + syscall, SFS_4ARGS for a four argument statfs(2) call, + and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument + statfs(2) call with the declarations in , + , or respectively). + Fix glitch in NetInfo support that could return garbage if + there was no "/locations/sendmail" property. From + David Meyer of the University of Virginia. + Change HASFLOCK from defined/not-defined to a 0/1 definition + to allow Linux to turn it off even though it is a + BSD-like system. + Allow setting of "ident" timeout to zero to turn off the ident + protocol entirely. + Make 7-bit stripping local to a connection (instead of to a + mailer); this allows you to specify that SMTP is a + 7-bit channel, but revert to 8-bit should it advertise + that it supports 8BITMIME. You still have to specify + mailer flag 7 to get this stripping at all. + Improve makesendmail script so it handles more cases automatically. + Tighten up restrictions on taking ownership of :include: files + to avoid problems on systems that allow you to give away + files. + Fix a problem that made it impossible to rebuild the alias + file if it was on a read-only file system. From + Harry Edmon of the University of Washington. + Improve MX randomization function. From John Gardiner Myers + of CMU. + Fix a minor glitch causing a bogus message to be printed (used + %s instead of %d in a printf string for the line number) + when a bad queue file was read. From Harry Edmon. + Allow $s to remain NULL on locally generated mail. I'm not + sure this is necessary, but a lot of people have complained + about it, and there is a legitimate question as to whether + "localhost" is legal as an 822-style domain. + Fix a problem with very short line lengths (mailer L= flag) in + headers. This causes a leading space to be added onto + continuation lines (including in the body!), and also + tries to wrap headers containing addresses (From:, To:, + etc) intelligently at the shorter line lengths. Problem + Reported by Lars-Johan Liman of SUNET Operations Center. + Log the real user name when logging syserrs, since these can have + security implications. Suggested by several people. + Fix address logging of cached connections -- it used to always + log the numeric address as zero. This is a somewhat + bogus implementation in that it does an extra system + call, but it should be an inexpensive one. Fix from + Motonori Nakamura. + Tighten up handling of short syslog buffers even more -- there + were cases where the outgoing relay= name was too long + to share a line with delay= and mailer= logging. + Limit the overhead on split envelopes to one open file descriptor + per envelope -- previously the overhead was three + descriptors. This was in response to a problem reported + by P{r (Pell) Emanuelsson. + Fixes to better handle the case of unexpected connection closes; + this redirects the output to the transcript so the info + is not lost. From Eric Wassenaar. + Fix potential string overrun if you macro evaluate a string that + has a naked $ at the end. Problem noted by James Matheson + . + Make default error number on $#error messages 553 (``Requested + action not taken: mailbox name not allowed'') instead of + 501 (``Syntax error in parameters or arguments'') to + avoid bogus "protocol error" messages. + Strip off any existing trailing dot on names during $[ ... $] + lookup. This prevents it from ending up with two dots + on the end of dot terminated names. From Wesley Craig + of the University of Michigan and Bryan Costales of ICSI. + Clean up file class reading so that the debugging information is + more informative. It hadn't been using setclass, so you + didn't see the class items being added. + Avoid core dump if you are running a version of sendmail where + NIS is compiled in, and you specify an NIS map, but + NIS is not running. Fix from John Oleynick of + Rutgers. + Diagnose bizarre case where res_search returns a failure value, + but sets h_errno to a success value. + Make sure that "too many hops" messages are considered important + enough to send an error to the Postmaster (that is, the + address specified in the P option). This fix should + help problems that cause the df file to be left around + sometimes -- unfortunately, I can't seem to reproduce + the problem myself. + Avoid core dump (null pointer reference) on EXPN command; this + only occurred if your log level was set to 10 or higher + and the target account was an alias or had a .forward file. + Problem noted by Janne Himanka. + Avoid "denial of service" attacks by someone who is flooding your + SMTP port with bad commands by shutting the connection + after 25 bad commands are issued. From Kyle Jones of + UUNET. + Fix core dump on error messages with very long "to" buffers; + fmtmsg overflows the message buffer. Fixed by trimming + the to address to 203 characters. Problem reported by + John Oleynick. + Fix configuration for HASFLOCK -- there were some spots where + a #ifndef was incorrectly #ifdef. Pointed out by + George Baltz of the University of Maryland. + Fix a typo in savemail() that could cause the error message To: + lists to be incorrect in some places.

Problem noted by James M.R.Matheson + of Cambridge University. + Avoid giving ``warning: foo owned process doing -bs'' messages + if they use ``MAIL FROM:'' where foo is their true + user name. Suggested by Andreas Stolcke of ICSI. + Change the NAMED_BIND compile flag to be a 0/1 flag so you can + override it easily in the Makefile -- that is, you can + turn it off using -DNAMED_BIND=0. + If a gethostbyname(...) of an address with a trailing dot fails, + try it without the trailing dot. This is because if + you have a version of gethostbyname() that falls back + to NIS or the /etc/hosts file it will fail to find + perfectly reasonable names that just don't happen to + be dot terminated in the hosts file. You don't want to + strip the dot first though because we're trying to ensure + that country names that match one of your subdomains get + a chance. + PRALIASES: fix bogus output on non-null-terminated strings. + From Bill Gianopoulos of Raytheon. + CONFIG: Avoid rewriting anything that matches $w to be $j. + This was in code intended to only catch the self-literal + address (that is, [1.2.3.4], where 1.2.3.4 is your + IP address), but the code was broken. However, it will + still do this if $M is defined; this is necessary to + get client configurations to work (sigh). Note that this + means that $M overrides :mailname entries in the user + database!

From + Steve Cliffe . + CONFIG: Fix bug that broke news.group.USENET mappings. + CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, + and USENET_MAILER_MAX to tweak the maximum message + size for various mailers. + CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] + instead of assuming that it is "inews" for consistency + with other mailers. From Michael Corrigan of UC San Diego. + CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, + qualify the address in the SMTP envelope as user@{relay|hub} + instead of user@$j. From Bill Wisner of The Well. + CONFIG: Fix route-addr syntax in nullrelay configuration set. + CONFIG: Don't turn off case mapping of user names in the local + mailer for IRIX. This was different than most every other + system. + CONFIG: Avoid infinite loops on certainly list:; syntaxes in + envelope. Noted by Thierry Besancon + . + CONFIG: Don't include -z by default on uux line -- most systems + don't want it set by default. Pointed out by Philippe + Michel of Thomson CSF. + CONFIG: Fix some bugs with mailertables -- for example, if your + host name was foo.bar.ray.com and you matched against + ".ray.com", the old implementation bound %1 to "bar" + instead of "foo.bar". Also, allow "." in the mailertable + to match anything -- essentially, take over SMART_HOST. + This also moves matching of explicit local host names + before the mailertable so they don't have to be special + cased in the mailertable data. Reported by Bill + Gianopoulos of Raytheon; the fix for the %1 binding + problem was contributed by Nicholas Comanos of the + University of Sydney. + CONFIG: Don't include "root" in class $=L (users to deliver + locally, even if a hub or relay exists) by default. + This is because of the known bug where definition of + both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore + both and deliver into the local mailbox. + CONFIG: Move up bitdomain and uudomain handling so that they + are done before .UUCP class matching; uudomain was + reported as ineffective before. This also frees up + diversion 8 for future use. Problem reported by Kimmo + Suominen. + CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) + into host names. As pointed out by Jonathan Kamens, + these are often used because either the forward or reverse + mapping is broken; this translation makes it broken again. + DOC: Clarify $@ and $: in the Install & Op Guide.

From + Bob Campbell at U.C. Berkeley. + Security fix: group ids were not completely set when programs + were invoked. This caused programs to have group + permissions they should not have had (usually group + daemon instead of their own group). In particular, + Perl scripts would refuse to run. + Security: check to make sure files that are written are not + symbolic links (at least under some circumstances). + Although this does not respond to a specific known + attack, it's just a good idea. Suggested by + Christian Wettergren. + Security fix: if a user had an NFS mounted home directory on + a system with a restricted shell listed in their + /etc/passwd entry, they could still execute any + program by putting that in their .forward file. + This fix prevents that by insisting that their shell + appear in /etc/shells before allowing a .forward to + execute a program or write a file. You can disable + this by putting "*" in /etc/shells. It also won't + permit world-writable :include: files to reference + programs or files (there's no way to disable this). + These behaviours are only one level deep -- for + example, it is legal for a world-writable :include: + file to reference an alias that writes a file, on + the assumption that the alias file is well controlled. + Security fix: root was not treated suspiciously enough when + looking into subdirectories. This would potentially + allow a cracker to examine files that were publicly + readable but in a non-publicly searchable directory. + Fix a problem that causes an error on QUIT on a cached + connection to create problems on the current job. + These are typically unrelated, so errors occur in + the wrong place. + Reset CurrentLA in sendall() -- this makes sendmail queue + runs more responsive to load average, and fixes a + problem that ignored the load average in locally + generated mail. From Eric Wassenaar. + Fix possible core dump on aliases with null LHS. From + John Orthoefer of BB&N. + Revert to using flock() whenever possible -- there are just + too many bugs in fcntl() locking, particularly over + NFS, that cause sendmail to fail in perverse ways. + Fix a bug that causes the connection cache to get confused + when sending error messages. This resulted in + "unexpected close" messages. It should fix itself + on the following queue run. Problem noted by + Liudvikas Bukys of the University of Rochester. + Include $k in $=k as documented in the Install & Op Guide. + This seems odd, but it was documented.... From + Michael Corrigan of UCSD. + Fix problem that caused :include:s from alias files to be + forced to be owned by root instead of daemon + (actually DefUid). From Tim Irvin. + Diagnose unrecognized I option values -- from Mortin Forssen + of the Chalmers University of Technology. + Make "error" mailer work consistently when there is no error + code associated with it -- previously it returned OK + even though there was a real problem.

Problem noted by Liudvikas Bukys. + Fix core dump on SMTP mail to programs that failed -- it tried + to go to a "next MX host" when none existed, causing + a core dump. From der Mouse at McGill University. + Change IDENTPROTO from a defined/not defined to a 0/1 switch; + this makes it easier to turn it off (using + -DIDENTPROTO=0 in the Makefile). From der Mouse. + Fix YP_MASTER_NAME store to use the unupdated result of + gethostname() (instead of myhostname(), which tries + to fully qualify the name) to be consistent with + SunOS. If your hostname is unqualified, this fixes + transfers to slave servers. Bug noted by Keith + McMillan of Ameritech Services, Inc. + Fix Ultrix problem: gethostbyname() can return a very large + (> 500) h_length field, which causes the sockaddr + to be trashed. Use the size of the sockaddr instead. + Fix from Bob Manson of Ohio State. + Don't assume "-a." on host lookups if NAMED_BIND is not + defined -- this confuses gethostbyname on hosts + file lookups, which doesn't understand the trailing + dot convention. + Log SMTP server subprocesses that die with a signal instead + of from a clean exit. + If you don't have option "I" set, don't assume that a DNS + "host unknown" message is authoritative -- it + might still be found in /etc/hosts. + Fix a problem that would cause Deferred: messages to be sent + as the subject of an error message, even though the + actual cause of a message was more severe than that. + Problem noted by Chris Seabrook of OSSI. + Fix race condition in DBM alias file locking. From Kyle + Jones of UUNET. + Limit delivery syslog line length to avoid bugs in some + versions of syslog(3). This adds a new compile time + variable SYSLOG_BUFSIZE. From Jay Plett of Princeton + University, which is in turn derived from IDA. + Fix quotes inside of comments in addresses -- previously + it insisted that they be balanced, but the 822 spec + says that they should be ignored. + Dump open file state to syslog upon receiving SIGUSR1 (for + debugging). This also evaluates ruleset 89, if set + (with the null input), and logs the result. This + should be used sparingly, since the rewrite process + is not reentrant. + Change -qI, -qR, and -qS flags to be case-insensitive as + documented in the Bat Book. + If the mailer returned EX_IOERR or EX_OSERR, sendmail did not + return an error message and did not requeue the message. + Fix based on code from Roland Dirlewanger of + Reseau Regional Aquarel, Bordeaux, France. + Fix a problem that caused a seg fault if you got a 421 error + code during some parts of connection initialization. + I've only seen this when talking to buggy mailers on + the other end, but it shouldn't give a seg fault in + any case. From Amir Plivatsky. + Fix core dump caused by a ruleset call that returns null. + Fix from Bryan Costales of ICSI. + Full-Name: field was being ignored.

From + Dave Morrison of Oracle. + Improve several of the error messages printed by "mailq" + to include a host name or other useful information. + Add NetInfo preliminary support for NeXT systems. From Vince + DeMarco. + Fix a glitch that sometimes caused :include:s that pointed to + NFS filesystems that were down to give an "aliasing/ + forwarding loop broken" message instead of queueing + the message for retry. Noted by William C Fenner of + the NRL Connection Machine Facility. + Fix a problem that could cause a core dump if the input sequence + had (or somehow acquired) a \231 character. + Make sure that route-addrs always have around + them in non-SMTP envelopes (SMTP envelopes already do + this properly). + Avoid weird headers on unbalanced punctuation of the form: + ``Joe User ; this + has uucp-dom semantics but old UUCP syntax. This + also permits "uucp-old" as an alias for "uucp" and + "uucp-new" as a synonym for "suucp" for consistency. + CONFIG: add POP mailer support (from Kimmo Suominen + ). + CONFIG: drop CSNET_RELAY support -- CSNET is long gone. + CONFIG: fix bug caused with domain literal addresses (e.g., + ``[128.32.131.12]'') when FEATURE(allmasquerade) + was set; it would get an additional @masquerade.host + added to the address. Problem noted by Peter Wan + of Georgia Tech. + CONFIG: make sure that the local UUCP name is in $=w. From + Jim Murray of Stratus. + CONFIG: changes to UUCP rewriting to simulate IDA-style "V" + mailer flag.

From Mark Delany. + MAILSTATS: print sums of columns (total messages & kbytes + in and out of the system). From Tom Ferrin of UC + San Francisco Computer Graphics Lab. + SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: + On HP-UX, /etc/sendmail.cf has been moved to + /usr/lib/sendmail.cf to match HP sendmail. + Permissions have been tightened up on world-writable + :include: files and accounts that have shells + that are not listed in /etc/shells.

From Eric + Wassenaar of the Dutch National Institute for Nuclear + and High-Energy Physics. + Fix some problems that caused queue runs to do "too much work", + such as double-reading the Errors-To: header. From + Eric Wassenaar. + Error messages on writing the temporary file (including the + data file) were getting suppressed in SMTP -- this + fix causes them to be properly reported. From Eric + Wassenaar. + Some changes to support AF_UNIX sockets -- this will only + really become relevant in the next release, but some + people need it for local patches. From Michael + Corrigan of UC San Diego. + Use dynamically allocated memory (instead of static buffers) + for macros defined in initsys() and settime(); since + these can have different values depending on which + envelope they are in. From Eric Wassenaar. + Improve logging to show ctladdr on to= logging; this tells you + what uid/gid processes ran as. + Fix a problem that caused error messages to be discarded if + the sender address was unparseable for some reason; + this was supposed to fall back to the "return to + postmaster" case. + Improve aliaswait backoff algorithm. + Portability patches for Linux (8.6.3 required another header + file) (from Karl London) and SCO UNIX. + CONFIG: patch prog mailer to not strip host name off of envelope + addresses (so that it matches local again). From + Christopher Davis. + CONFIG: change uucp-dom mailer so that "<>" translates to $n; + this prevents uux from seeing lines with null names like + ``From Sat Oct 30 14:55:31 1993''. From Motonori + Nakamura of Kyoto University. + CONFIG: handle syntax correctly. This isn't legal, but + it shouldn't fail miserably. From Motonori Nakamura. + +8.6.2/8.6.2 93/10/15 + Put a "successful delivery" message in the transcript for + addresses that get return-receipts. + Put a prominent "this is only a warning" message in warning + messages -- some people don't read carefully enough + and end up sending the message several times. + Include reason for temporary failure in the "warning" return + message. Currently, it just says "cannot send for + four hours". + Fix the "Original message received" time generated for + returntosender messages. It was previously listed as + the current time. Bug reported by Eric Hagberg of + Cornell University Medical College. + If there is an error when writing the body of a message, + don't send the trailing dot and wait for a response + in sender SMTP, as this could cause the connection to + hang up under some bizarre circumstances. From Eric + Wassenaar. + Fix some server SMTP synchronization problems caused when + connections fail during message collection. From + Eric Wassenaar. + Fix a problem that can cause srvrsmtp to reject mail if the + name server is down -- it accepts the RCPT but rejects + the DATA command. Problem reported by Jim Murray of + Stratus. + Fix a problem that can cause core dumps if the config file + incorrectly resolves to a null hostname. Reported by + Allan Johannesen of WPI. + Non-root use of -C flag, dangerous -f flags, and use of -oQ + by non-root users were not put into + X-Authentication-Warning:s as intended because the + config file hadn't set the PrivacyFlags yet. Fix + from Sven-Ove Westberg of the University of Lulea. + Under very odd circumstances, the alias file rebuild code + could get confused as to whether a database was + open or not. + Check "vendor code" on the end of V lines -- this is + intended to provide a hook for vendor-specific + configuration syntax.

Pointed out by Michael Corrigan of UCSD. + Announce name of host we are chatting when we get errors; this + is an IDA-ism suggested by Christophe Wolfhugel. + Portability fixes for Alpha OSF/1 (from Anthony Baxter of the + Australian Artificial Intelligence Institute), SCO Unix + (from Murray Kucherawy of Hookup Communication Corp.), + NeXT (from Vince DeMarco and myself), Linux (from + Karl London ), BSDI (from + Christophe Wolfhugel, and SVR4 on Dell (from Kimmo + Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. + Some changes to get around gcc optimizer bugs. From Takahiro + Kanbe. + Fix error recovery in queueup if another tf file of the same + name already exists. Problem stumbled over by Bill + Wisner of The Well. + Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. + Problem noted by Keith McMillan of Ameritech Services. + Deal with group permissions properly when opening .forward and + :include: files. This relaxes the 8.1C restrictions + slightly more. This includes proper setting of groups + when reading :include: files, allowing you to read some + files that you should be able to read but have previously + been denied unless you owned them or they had "other" + read permission. + Make certain that $j is in $=w (after the .cf is read) so that + if the user is forced to override some silly system, + MX suppression will still work. + Fix a couple of efficiency problems where newstr was double- + calling expensive routines. In at least one case, it + wasn't guaranteed that they would always return the + same result. Problem noted by Christophe Wolfhugel. + Fix null pointer dereference in putoutmsg -- only on an error + condition from a non-SMTP mailer. From Motonori + Nakamura. + Macro expand "C" line class definitions before scanning so that + "CX $Z" works. + Fix problem that caused error message to be sent while still + trying to send the original message if the connection + is closed during a DATA command after getting an error + on an RCPT command (pretty obscure). Problem reported + by John Myers of CMU. + Fix reply to NOOP to be 250 instead of 200 -- this is a long + term bug. + Fix a nasty bug causing core dumps when returning the "warning: + cannot deliver for N hours -- will keep trying" message; + it only occurred if you had PostMasterCopy set and + only on some architectures. Although sendmail would + keep trying, it would send error messages on each + queue interval. This is an important fix. + Allow u and g options to take user and group names respectively. + Don't do a chdir into the queue directory in -bt mode to make + ruleset testing a bit easier. + Don't allow users to turn off logging (using -oL) on the command + line -- command line can only raise, not lower, logging + level. + Set $u to the original recipient on the SMTP transaction or on + the command line. This is only done if there is exactly + one recipient. Technically, this does not meet the + specs, because it does not guarantee a domain on the + address. + Fix a problem that dumped error messages on bad addresses if + you used the -t flag. Problem noted by Josh Smith of + Harvey Mudd College. + Given an address such as `` '', auto-quote the first + ``'' part, giving ``"" ''. This is to + avoid the problem of people who use angle brackets in + their full name information. + Fix a null pointer dereference if you set option "l", have + an Errors-To: header in the message, and have Errors-To: + defined in the config file H lines. From J.R. Oldroyd. + Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get + wrong when compiling. Suggested by Rick McCarty of TI. + Fix a problem that could pass negative SIZE parameter if the + df file got lost; this would cause servers to always + give a temporary failure, making the problem even worse. + Problem noted by Allan Johannesen of WPI. + Add "ident" timeout (one of the "r" option selectors) for IDENT + protocol timeouts (30s default). Requested by Murray + Kucherawy of HookUp Communication Corp. to handle bogus + PC TCP/IP implementations. + Change $w default definition to be just the first component of + the domain name on config level 5. The $j macro defaults + to the FQDN; $m remains as before. This lets well-behaved + config files use any of the short, long, or subdomain + names. + Add makesendmail script in src to try to automate multi-architecture + builds. I know, this is sub-optimal, but it is still + helpful. + Fix very obscure race condition that can cause a queue run to + get a queue file for an already completed job. This + problem has existed for years. Problem noted by the + long suffering Allan Johannesen of WPI. + Fix a problem that caused the raw sender name to be passed to + udbsender instead of the canonified name -- this caused + it to sometimes miss records that it should have found. + Relax check of name on HELO packet so that a program using -bs + that claims to be itself works properly. + Restore rewriting of $: part of address through 2, R, 4 in + buildaddr -- this requires passing a lot of flags to get + it right. Unlike old versions, this ONLY rewrites + recipient addresses, not sender addresses. + Fix a bug that caused core dumps in config files that cannot + resolve /file/name style addresses. Fix from Jonathan + Kamens of OpenVision Technologies. + Fix problem with fcntl locking that can cause error returns to + be lost if the lock is lost; this required fully + queueing everything, dropping the envelope (so errors + would get returned), and then re-reading the queue from + scratch. + Fix a problem that caused aliases that redefine an otherwise + true address to still send to the original address + if and only if the alias failed in certain bizarre + ways (e.g, if they pointed at a list:; syntax address). + Problem pointed out by Jonathan Kamens. + Remove support for frozen configuration files. They caused + more trouble than it was worth. + Fix problem that can cause error messages to get ignored when + using both -odb and -t flags. Problem noted by Rob + McNicholas at U.C. Berkeley. + Include all "normal" variations on hostname in $=w. For example, + if the host name is vangogh.cs.berkeley.edu, $=w will + contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. + Add "restrictqrun" privacy flag -- without this, anyone can run + the queue. + Reset SmtpPhase global on initial connection creation so that + messages don't come out with stale information. + Pass an "ext" argument to lockfile so that error/log messages + will properly reflect the true filename being locked. + Put all [...] address forms into $=w -- this eliminates the need + for MAXIPADDR in conf.h. Suggested by John Gardiner + Myers of CMU. + Fix a bug that can cause qf files to be left around even after + an SMTP RSET command. Problem and fix from Michael + Corrigan. + Don't send a PostMasterCopy to errors when the Precedence: is + negative. Error reports still go to the envelope + sender address. + Add LA_SHORT for load averages. + Lock sendmail.st file when posting statistics. + Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to + set the size of the TCP send and receive buffers; if you + run over a slow slip line you may need to set these down + (although it would be better to fix the SLIP implementation + so that it's not necessary to recompile every program + that does bulk data transfer). + Allow null defaults on $( ... $) lookups. Problem reported by + Amir Plivatsky. + Diagnose crufty S and V config lines. This resulted from an + observation that some people were using the SITE macro + without the SITECONFIG macro first, which was causing + bogus config files that were not caught. + Fix makemap -f flag to turn off case folding (it was turning it + on instead). THIS IS A USER VISIBLE CHANGE!!! + Fix a problem that caused multiple error messages to be sent if + you used "sendmail -t -oem -odb", your system uses fcntl + locking, and one of the recipient addresses is unknown. + Reset uid earlier in include() so that recursive .forwards or + :include:s don't use the wrong uid. + If file descriptor 0, 1, or 2 was closed when sendmail was + called, the code to recover the descriptor was broken. + This sometimes (only sometimes) caused problems with the + alias file. Fix from Motonori Nakamura. + Fix a problem that caused aliaswait to go into infinite recursion + if the @:@ metasymbol wasn't found in the alias file. + Improve error message on newaliases if database files cannot be + opened or if running with no database format defined. + Do a better estimation of the size of error messages when NoReturn + is set. Problem noted by P{r (Pell) Emanuelsson. + Fix a problem causing the "c" option (don't connect to expensive + mailers) to be ignored in SMTP. Problem noted and the + solution suggested by Robert Elz of The University of + Melbourne. + Improve connection caching algorithm by passing "[host]" to + hostsignature, which strips the square brackets and + returns the real name. This allows mailertable entries + to match regular entries. + Re-enable Return-Receipt-To: -- people seem to want this stupid + feature, even if it doesn't work right. + Catch and log attempts to try the "wiz" command in server SMTP. + This also ups the log level from LOG_NOTICE to LOG_CRIT. + Be more generous at assigning $z to the home directory -- do this + for programs that are specified through a .forward file. + Fix from Andrew Chang of Sun Microsystems. + Always save a fatal error message in preference to a non-fatal + error message so that the "subject" line of return + messages is the best possible. + CONFIG: reduce the number of quotes needed to quote configuration + parameters with commas: two quotes should work now, e.g., + define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). + CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom + connections (domain-ized UUCP). + CONFIG: fix bug in default maps (-o must be before database file + name). Pointed out by Christophe Wolfhugel. + CONFIG: add FEATURE(nodns) to state that we are not relying on + DNS. This would presumably be used in UUCP islands. + CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). + CONFIG: log $u in Received: line. This is in technical violation + of the standards, since it doesn't guarantee a domain + on the address. + CONFIG: don't assume "m" in local mailer flags -- this means that + if you redefine LOCAL_MAILER_FLAGS you will have to include + the "m" flag should you want it. Apparently some Solaris 2.2 + installations can't handle multiple local recipients. + Problem noted by Josh Smith. + CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). + CONFIG: change default version level from 4 to 5. + CONFIG: add FEATURE(nullclient) to create a config file that + forwards all mail to a hub without ever looking at the + addresses in any detail. + CONFIG: properly strip mailer: information off of relays when + used to change .BITNET form into %-hack form. + CONFIG: fix a problem that caused infinite loops if presented + with an address such as "!foo". + CONFIG: check for self literal (e.g., [128.32.131.12]) even if + the reverse "PTR" mapping is broken. There's a better + way to do this, but the change is fairly major and I + want to hold it for another release. Problem noted by + Bret Marquis. + +8.5/8.5 93/07/23 + Serious bug: if you used a command line recipient that was unknown + sendmail would not send a return message (it was treating + everything as though it had an SMTP-style client that + would do the return itself). Problem noted by Josh Smith. + Change "trymx" option in getcanonname() to ignore all MX data, + even during a T_ANY query. This actually didn't break + anything, because the only time you called getcanonname + with !trymx was if you already knew there were no MX + records, but it is somewhat cleaner. From Motonori + Nakamura. + Don't call getcanonname from getmxrr if you already know there + are no DNS records matching the name. + Fix a problem causing error messages to always include "The + original message was received ... from localhost". + The correct original host information is now included. + Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their + version of "test" doesn't have the -x flag). Change it + to use -f instead. From John Myers. + CONFIG: 8.4 mistakenly set the default SMTP-style mailer to + esmtp -- it should be smtp. + CONFIG: send all relayed mail using confRELAY_MAILER (defaults + to "relay" (a variant of "smtp") if MAILER(smtp) is used, + else "suucp" if MAILER(uucp) is used, else "unknown"); + this cleans up the configs somewhat. This fixes a serious + problem that caused route-addrs to get mistaken as relays, + pointed out by John Myers. WARNING: this also causes + the default on SMART_HOST to change from "suucp" to + "relay" if you have MAILER(smtp) specified. + +8.4/8.4 93/07/22 + Add option `w'. If you receive a message that comes to you because + you are the best (lowest preference) target of an MX, and + you haven't explicitly recognized the source MX host in + your .cf file, this option will cause you to try the target + host directly (as if there were no MX for it at all). If + `w' is not set, this case is a configuration error. + Beware: if `w' is set, senders may get bogus errors like + "message timed out" or "host unknown" for problems that + are really configuration errors. This option is + disrecommended, provided only for compatibility with + UIUC sendmail. + Fix a problem that caused the incoming socket to be left open + when sendmail forks after the DATA command. This caused + calling systems to wait in FIN_WAIT_2 state until the + entire list was processed and the child closed -- a + potentially prodigious amount of time. Problem noted + by Neil Rickert. + Fix problem (created in 6.64) that caused mail sent to multiple + addresses, one of which was a bad address, to completely + suppress the sending of the message. This changes + handling of EF_FATALERRS somewhat, and adds an + EF_GLOBALERRS flag. This also fixes a potential problem + with duplicate error messages if there is a syntax error + in the header of a message that isn't noticed until late + in processing. Original problem pointed out by Josh Smith + of Harvey Mudd College. This release includes quite a bit + of dickering with error handling (see below). + Back out SMTP transaction if MAIL gets nested 501 error. This + will only hurt already-broken software and should help + humans. + Fix a problem that broke aliases when neither NDBM nor NEWDB were + compiled in. It would never read the alias file. + Repair unbalanced `)' and `>' (the "open" versions are already + repaired). + Logging of "done" in dropenvelope() was incorrect: it would + log this even when the queue file still existed. Change + this to only log "done" (at log level 11) when the + queue file is actually removed. From John Myers. + Log "lost connection" in server SMTP at log level 20 if there + is no pending transaction. Some senders just close the + connection rather than sending QUIT. + Fix a bug causing getmxrr to add a dot to the end of unqualified + domains that do not have MX records -- this would cause + the subsequent host name lookup to fail. The problem + only occurred if you had FEATURE(nocanonify) set. + Problem noted by Rick McCarty of Texas Instruments. + Fix invocation of setvbuf when passed a -X flag -- I had + unwittingly used an ANSI C extension, and this caused + core dumps on some machines. + Diagnose self-destructive alias loops on RCPT as well as EXPN. + Previously it just gave an empty send queue, which + then gave either "Need RCPT (recipient)" at the DATA + (confusing, since you had given an RCPT command which + returned 250) or just dropped the email, depending on + whether you were running VERBose mode. Now it usually + diagnoses this case as "aliasing/forwarding loop broken". + Unfortunately, it still doesn't adequately diagnose + some true error conditions. + Add internal concept of "warning messages" using 6xx codes. + These are not reported only to Postmaster. Unbalanced + parens, brackets, and quotes are printed as 653 codes. + They are always mapped to 5xx codes before use in SMTP. + Clean up error messages to tell both the actual address that + failed and the alias they arose from. This makes it + somewhat easier to diagnose problems. Difficulty noted + by Motonori Nakamura. + Fix a problem that inappropriately added a ctladdr to addresses + that shouldn't have had one during a queue run. This + caused error messages to be handled differently during + a queue run than a direct run. + Don't print the qf name and line number if you get errors during + the direct run of the queue from srvrsmtp -- this was + just extra stuff for users to crawl through. + Put command line flags on second line of pid file so you can + auto-restart the daemon with all appropriate arguments. + Use "kill `head -1 /etc/sendmail.pid`" to stop the + daemon, and "eval `tail -1 /etc/sendmail.pid`" to + restart it. + Remove the ``setuid(getuid())'' in main -- this caused the + IDENT daemon to screw up. This required that I change + HASSETEUID to HASSETREUID and complicate the mode + changing somewhat because both Ultrix and SunOS seem + to have a bug causing seteuid() to set the saved uid + as well as the effective. The program test/t_setreuid.c + will test to see if your implementation of setreuid(2) + is appropriately functional. + The FallBackMX (option V) handling failed to properly identify + fallback to yourself -- most of the code was there, + but it wasn't being enabled. Problem noted by Murray + Kucherawy of the University of Waterloo. + Change :include: open timeout from ETIMEDOUT to an internal + code EOPENTIMEOUT; this avoids adding "during SmtpPhase + with CurHostName" in error messages, which can be + confusing. Reported by Jonathan Kamens of OpenVision + Technologies. + Back out setpgrp (setpgid on POSIX systems) call to reset the + process group id. The original fix was to get around + some problems with recalcitrant MUAs, but it breaks + any call from a shell that creates a process group id + different from the process id. I could try to fix + this by diddling the tty owner (using tcsetpgrp or + equivalent) but this is too likely to break other + things. + Portability changes: + Support -M as equivalent to -oM on Ultrix -- apparently + DECnet calls sendmail with -MrDECnet -Ms -bs + instead of using standard flags. Oh joy. This + behaviour reported by Jon Giltner of University + of Colorado. + SGI IRIX -- this includes several changes that should + help other strict ANSI compilers. + SCO Unix -- from Murray Kucherawy of HookUp Communication + Corporation. + Solaris running the Sun C compiler (which despite the + documentation apparently doesn't define + __STDC__ by default). + ConvexOS from Eric Schnoebelen of Convex. + Sony NEWS workstations and Omron LUNA workstations from + Motonori Nakamura. + CONFIG: add confTRY_NULL_MX_LIST to set option `w'. + CONFIG: delete `C' and `e' from default SMTP mailers flags; + several people have made a good argument that this + creates more problems than it solves (although this + may prove painful in the short run). + CONFIG: generalize all the relays to accept a "mailer:host" + format. + CONFIG: move local processing in ruleset 0 into a new ruleset + 98 (8 on old sendmail). Domain literal [a.b.c.d] + addresses are also passed through this ruleset. + CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, + internet-style addresses would "fall off the end" of + ruleset zero and be interpreted as local -- however, + the angle brackets confused the recursive call. + These are now diagnosed as "Unrecognized host name". + CONFIG: USENET rules weren't included in S0 because of a mistaken + ifdef(`_MAILER_USENET_') instead of + ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik + of SINTEF RUNIT, Oslo. + CONFIG: move up LOCAL_RULE_0 processing so that it happens very + early in ruleset 0; this allows .mc authors to bypass + things like the "short circuit" code for local addresses. + Prompted by a comment by Bill Wisner of The Well. + CONFIG: add confSMTP_MAILER to define the mailer used (smtp or + esmtp) to send SMTP mail. This allows you to default + to esmtp but use a mailertable or other override to + deal with broken servers. This logic was pointed out + to me by Bill Wisner. Ditto for confLOCAL_MAILER. + Changes to cf/sh/makeinfo.sh to make it portable to SVR4 + environments. Ugly as sin. + +8.3/8.3 93/07/13 + Fix setuid problems introduced in 8.2 that caused messages + like "Cannot create qfXXXXXX: Invalid argument" + or "Cannot reopen dfXXXXXX: Permission denied". This + involved a new compile flag "HASSETEUID" that takes + the place of the old _POSIX_SAVED_IDS -- it turns out + that the POSIX interface is broken enough to break + some systems badly. This includes some fixes for + HP-UX. Also fixes problems where the real uid is + not reset properly on startup (from Neil Rickert). + Fix a problem that caused timed out messages to not report the + addresses that timed out. Error messages are also more + "user friendly". + Drop required bandwidth on connections from 64 bytes/sec to + 16 bytes/sec. + Further Solaris portability changes -- doesn't require the BSD + compatibility library. This also adds a new + "HASGETDTABLESIZE" compile flag which can be used if + you want to use getdtablesize(2) instead of sysconf(2). + These are loosely based on changes from David Meyer at + University of Oregon. This now seems to work, at least + for quick test cases. + Fix a problem that can cause duplicate error messages to be + sent if you are in SMTP, you send to multiple addresses, + and at least one of those addresses is good and points + to an account that has a .forward file (whew!). + Fix a problem causing messages to be discarded if checkcompat() + returned EX_TEMPFAIL (because it didn't properly mark + the "to" address). Problem noted by John Myers. + Fix dfopen to return NULL if the open failed; I was depending + on fdopen(-1) returning NULL, which isn't the case. This + isn't serious, but does result in weird error diagnoses. + From Michael Corrigan. + CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of + messages sent through UUCP-family mailers. Suggested + by Bill Wisner of The Well. + CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, + include a "uucp-dom" mailer that uses domain-style + addressing. Suggested by Bill Wisner. + CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match + LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by + Christophe Wolfhugel. + CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. + +8.2/8.2 93/07/11 + Don't drop out on config file parse errors in -bt mode. + On older configuration files, assume option "l" (use Errors-To + header) for back compatibility. NOTE: this DOES NOT + imply an endorsement of the Errors-To: header in any way. + Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? + Don't log errors on EHLO -- it isn't a "real" error for an old + SMTP server to give an error on this command, and + logging it in the transcript can be confusing. Fix + from Bill Wisner. + IRIX compatibility changes provided by Dan Rich + . + Solaris 2 compatibility changes. Provided by Bob Cunningham + , John Oleynick + + Debugging: -d17 was overloaded (hostsignature and usersmtp.c); + move usersmtp (smtpinit and smtpmailfrom) to -d18 to + match the other flags in that file. + Flush transcript before fork in mailfile(). From Eric Wassenaar. + Save h_errno in mci struct and improve error message display. + Changes from Eric Wassenaar. + Open /dev/null for the transcript if the create of the xf file + failed; this avoids at least one possible null pointer + reference in very weird cases. From Eric Wassenaar. + Clean up statistics gathering; it was over-reporting because of + forks. From Eric Wassenaar. + Fix problem that causes old Return-Path: line to override new + Return-Path: line (conf.c needs H_FORCE to avoid + re-using old value). From Motonori Nakamura. + Fix broken -m flag in K definition -- even if -m (match only) + was specified, it would still replace the key with the + value. Noted by Rick McCarty of Texas Instruments. + If the name server timed out over several days, no "timed out" + message would ever be sent back. The timeout code + has been moved from markfailure() to dropenvelope() + so that all such failures should be diagnosed. Pointed + out by Christophe Wolfhugel and others. + Relax safefile() constraints: directories in an include or + forward path must be readable by self if the controlling + user owns the entry, readable by all otherwise (e.g., + when reading your .forward file, you have to own and + have X permission in it; everyone needs X permission in + the root and directories leading up to your home); + include files must be readable by anyone, but need not + be owned by you. + If _POSIX_SAVED_IDS is defined, setuid to the owner before + reading a .forward file; this gets around some problems + on NFS mounts if root permission is not exported and + the user's home directory isn't x'able. + Additional NeXT portability enhancements from Axel Zinser. + Additional HP-UX portability enhancements from Brian Bullen. + Add a timeout around SMTP message writes; this assumes you can + get throughput of at least 64 bytes/second. Note that + this does not impact the "datafinal" default, which + is separate; this is just intended to work around + network clogs that will occur before the final dot + is sent. From Eric Wassenaar. + Change map code to set the "include null" flag adaptively -- + it initially tries both, but if it finds anything + matching without a null it never tries again with a + null and vice versa. If -N is specified, it never + tries without the null and creates new maps with a + null byte. If -O is specified, it never tries with + the null (for efficiency). If -N and -O are specified, + you get -NO (get it?) lookup at all, so this would + be a bad idea. If you don't specify either -N or -O, + it adapts. + Fix recognition of "same from address" so that MH submissions + will insert the appropriate full name information; + this used to work and got broken somewhere along the + way. + Some changes to eliminate some unnecessary SYSERRs in the + log. For example, if you lost a connection, don't + bother reporting that fact on the connection you lost. + Add some "extended debugging" flags to try to track down + why we get occasional problems with file descriptor + one being closed when execing a mailer; it seems to + only happen when there has been another error in the + same transaction. This requires XDEBUG, defined + by default in conf.h. + Add "-X filename" command line flag, which logs both sides of + all SMTP transactions. This is intended ONLY for + debugging bad implementations of other mailers; start + it up, send a message from a mailer that is failing, + and then kill it off and examine the indicated log. + This output is not intended to be particularly human + readable. This also adds the HASSETVBUF compile + flag, defaulted on if your compiler defines __STDC__. + CONFIG: change SMART_HOST to override an SMTP mailer. If you + have a local net that should get direct connects, you + will need to use LOCAL_NET_CONFIG to catch these hosts. + See cf/README for an example. + CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle + sites that don't use the -d flag. + CONFIG: hide recipient addresses as well as sender addresses + behind $M if FEATURE(allmasquerade) is specified; this + has been requested by several people, but can break + local aliases. For example, if you mail to "localalias" + this will be rewritten as "localalias@masqueradehost"; + although initial delivery will work, replies will be + broken. Use it sparingly. + CONFIG: add FEATURE(domaintable). This maps unqualified domains + to qualified domains in headers. I believe this is + largely equivalent to the IDA feature of the same name. + CONFIG: use $U as UUCP name instead of $k. This permits you + to override the "system name" as your UUCP name -- + in particular, to use domain-ized UUCP names. From + Bill Wisner of The Well. + CONFIG: create new mailer "esmtp" that always tries EHLO + first. This is currently unused in the config files, + but could be used in a mailertable entry. + +8.1C/8.1B 93/06/27 + Serious security bug fix: it was possible to read any file on + the system, regardless of ownership and permissions. + If a subroutine returns a fully qualified address, return it + immediately instead of feeding it back into rewriting. + This fixes a problem with mailertable lookups. + CONFIG: fix some M4 frotz (concat => CONCAT) + +8.1B/8.1A 93/06/12 + Serious bug fix: pattern matching backup algorithm stepped by + two tokens in classes instead of one. Found by Claus + Assmann at University of Kiel, Germany. + +8.1A/8.1A 93/06/08 + Another mailertable fix.... + +8.1/8.1 93/06/07 + 4.4BSD freeze. No semantic changes. + +6.65/6.34 93/06/06 + Fix some lintish problems. + Fix some cases where server SMTP behaved poorly when handed bogus + input, pointed out by Eric Wassenaar. + CONFIG: fix some more (sigh) mailertable bugs -- thanks to + Motonori Nakamura of Kyoto University (again). + +6.64/6.33 93/06/05 + Don't send 050 (-v) information after the 250 response to a QUIT + command in srvrsmtp -- clients usually close the connection + at this point, and it causes bogus error messages. + Don't send messages that have errors on input (such as unbalanced + parentheses) during SMTP transactions, since a return + message has (probably) already been sent. + Give better diagnostics on timeouts during network reads, including + information similar to the SMTP phase. + Fix bug that caused SMTP messages to deliver synchronously; this + happened after the DATA 250, and hence caused reading the + next command to be delayed. + Ignore Errors-To: header unless 'l' (lower case el) header is + specified. The Errors-To: header violates RFC 1123. + Errors-To: was only needed to take the place of the + envelope sender in the days when most Unix mailers + didn't understand about the two kinds of senders. + Don't send warning messages in response to automatically generated + messages (that is, those From:<>). + CONFIG: fix some rather stupid typos in the mailertable code + pointed out by Motonori Nakamura of Kyoto University. + CONFIG: add confUSE_ERRORS_TO configuration option. + CONFIG: if ALWAYS_ADD_DOMAIN is selected, try to use $M + (masquerade name) instead of $j. + CONFIG: don't add dots to relay names (added in 6.29); it breaks + several things, and can be simulated by dot terminating + the names of relays. For example, use: + DBbit.net.relay. + (note the trailing dot). + +6.63/6.32 93/06/01 + Fix prototypes to eliminate chars in argument lists -- some + compilers are pissy about this. + Log protocol ($r) and body type if set so we can determine if + the adaptive algorithms are working. + Pessimize on locking of database files (particularly for NEWDB + databases) during opens. There were problems with + processes opening the file while it was rebuilt; since + NEWDB caches heavily, the reader opened an empty file, + which is an error. If your system has the ability to + lock atomically on open, this works properly; otherwise, + there are race conditions. + Check mod time on .pag file instead of .dir in NDBM aliases + because the .dir file doesn't get updated for small + alias files. From John Gardiner Myers of CMU. + More Solaris portability -- it now compiles on Solaris, but + hangs up in gethostbyname(). + Move setting of RES_DEBUG flag before first myhostname() call + so we can see name server traffic on that call. + Fsync() queue files. + Fix a problem that causes -bi to try to rebuild maps other than + the alias file(s). + Fix a problem that caused udb to reject entries from any but + the first database listed. + Rearrange doc subdirectory for 4.4BSD release tape. + CONFIG: put $r into the Received line. This was an oversight. + CONFIG: fix typo (call to ruleset 99 should have been ruleset 90). + CONFIG: move "auxiliary" subroutines to be in ruleset 90-99 + range -- in the long run, single digit rulesets may + become reserved for builtin use by sendmail. + CONFIG: fix major problem that causes host aliases (that is, + anything in $=w != $j) to not be recognized. This has + been around since 6.30. + +6.62/6.31 93/05/28 + BETA RELEASE + Fix recursive syserr (if there is an error printing a syserr + message). This makes the code much less eager to consider + a write error as serious. This also includes some + heuristics to be clever about closed connections. + Lock NEWDB files during gets. This requires version 1.5 or later + of the db library. If you have an older version, you + can use -DOLD_NEWDB. This will go away in a few weeks. + Fix problem causing aliases that use host maps to get overwritten. + Do appropriate byte swapping on port numbers in ident protocol + code. Fix from Allan Johannesen of WPI. + Defer opening of map files to the same time as alias files so that + the daemon will tend to pick up new versions more promptly. + Prototype a bunch more functions. + Some Solaris 2.1 changes (still doesn't link though). + Try to simplify Makefiles by including more subordinate #defines + in conf.h (based on OS type). + CONFIG: check for domains if FEATURE(mailertable) is defined. + For example, if the host name is "knecht.cs.berkeley.edu" + it will search the following mailertable keys: + knecht.cs.berkeley.edu + .cs.berkeley.edu + .berkeley.edu + .edu + This could be used to replace the special relays for bitnet + and similar nets. + +6.61/6.30 93/05/24 + Fix problem that prevented appending dots on canonified host + names. This breaks tons of config files -- very + important fix. + Fix improper pointer dereference in response to HELO command. + Fix core dump if debugging set in map_rewrite. + CONFIG: add FEATURE(always_add_domain) to always attach the + local domain (only impacts local mail). + CONFIG: try to avoid turning names into $j -- although + technically a host can only have one "canonical name", + it seems to be common practice to have several. + +6.60/6.29 93/05/22 + Major change: merge alias databases with maps. This expands and + changes the map class interface but fixes a bunch of bugs. + The important user-visible change is that the file name + in a K line now does not include the ".db" extension; this + is added automatically. Also, the -d (NIS domain) flag is + missing from the K config line; use @domain instead. + When compiling, the *_MAP names are gone -- just compile + in NDBM, NEWDB, and/or NIS support. + Announce mailer/host/user triple on -bv flag -- from Brian + Bullen of Stirling University. + Don't send more than one line in response to HELO -- it confuses + Pony Express, which then behaves very badly. However, + this change does send two line 220 greetings, with the + second line reading "ESMTP spoken here". The usersmtp + module recognizes this and goes into ESMTP mode regardless + of the setting of the "a" mailer flag. Thus, "a" means + "always try EHLO". + AIX portability changes (thanks to Christophe Wolfhugel of + Herve Schauer Consultants (Paris) for providing me with + an INSA account for this purpose). Lightly tested. Use + -D_AIX3. This probably breaks compatibility with some + older systems (e.g., 4.2bsd) but still works on SunOS + 4.1.2, Ultrix 4.2A, HP-UX 8.07, OSF/1 T1.3, and AIX 3.2.3. + Fix a problem causing an error message loop if the output channel + is hosed. + Add the Makefiles that I use for various environments -- some are + Berkeley make versions and some are old make versions. + My makefile for the NeXT box has gotten lost, alas! + PRALIASES: support for printing NEWDB databases. From + Michael J. Corrigan of U.C. San Diego. + CONFIG: don't pass pseudo-domains to $[ ... $] (if you have + a wildcard MX it can have weird results). From + Christophe Wolfhugel. + CONFIG: dot terminate relay hostnames in S0. From Christophe + Wolfhugel. + +6.59/6.28 93/05/13 + Log version with SMTP daemon startup message. + Adjust setproctitle to work on NetBSD and BSD/386. + Fix null pointer reference in MX fallback code. + A bunch of minor fixes from Eric Wassenaar: + If deliver cannot execv the mailer, return EX_OSERR + instead of EX_TEMPFAIL (to give better + error messages). + Consistently malloc e_message. + Catch degenerate case of calling returntosender() + with an empty returnq. + MIME reformatting. + +6.58/6.28 93/05/13 + Fix bug that can cause incorrect verbose display of user smtp + messages. + Disable SMTP VERB command if PRIV_NOEXPN is set (since this + could reveal the same information. + Allow failure when reading SMTP greeting message to go on to + next MX host. + Add "MIME-Version: 1.0" header if using MIME (this was NOT + included in RFC 1344, but Bill King of Allan-Bradley + Company forwarded me email from Nathaniel Borenstein + claiming that it was an inadvertent omission). + Don't use Content-Type: X-message-header. According to John + Myers of CMU, many MIME readers will completely ignore + the data if they don't recognize it. Instead, just + add a blank line to make it a legal (empty) message. + Fix problem causing dots to keep getting appended to cached + hostnames. This can cause buffer overrun conditions. + The problem was found by Erik Forsberg of Retix, + although I used a different bug fix than he provided. + Fix parsing of split header/envelope rewriting specs -- from + Eric Forsberg. + Fix from Eric Wassenaar to correct To: lists in error messages. + +6.57/6.28 93/05/11 + Fix minor glitch causing extra ctladdrs to be output to queue + file. Just an annoyance. + Cache results of name server canonification lookups to avoid + backed up queue runs. + Major rewrite of alias.c: considerable cleanup, plus sample + (untested) support for NIS aliases. The "A" option + can now be a comma separated list (or be repeated) -- + that is, you can have multiple alias databases. Each + database can have the syntax ``class:file''; if no class + is specified, the "implicit" class is assumed. Implicit + searches through a list of compiled in types -- hash, + dbm, nis, and stab. Alias files are searched in the + order they are listed. For example: + OAhash:/etc/aliases.local,/etc/aliases + OAnis:mail.aliases@my.nis.domain + first searches the hash database /etc/aliases.local, + then the regular /etc/aliases database, then the NIS + map "mail.aliases" in the NIS domain "my.nis.domain". + If in Verbose mode (probably from VERB command) run SMTP job + in foreground and don't do RCPT optimizations. + Add udb :mailsender as equivalent to owner- for regular aliases. + Delete option 8; add option 7 that means the opposite. That is, + default to 8-bit mode; a special option is needed to + force sendmail into 7 bit mode. + Send error messages in encapsulated MIME format. + New compile flag "NIS" that turns on NIS alias and NIS map + support. + Add "j" option to send error messages in MIME (RFC 1341) + encapsulated message format per RFC 1344. The + syntax is pretty ugly if you don't have MIME-aware + user agents. + Clean up message handling (for display in mailq output). + New setproctitle implementation for 4.4bsd. + Create files (such as ~/dead.letter) using mode FileMode (the + F option value) instead of 0666. + Fix bug causing output of EXPN command to not be fully qualified. + This may cause some problems with UUCP addresses that + will require some config file assistance -- specifically, + the $: part has to include the host name for this output + to make sense. + Fix a problem that sometimes diagnosed errors and still sent the + message if the header syntax was bad. + Fix a bug that caused an error message to be emailed when sendmail + was operating in -bv mode. + Add "ListenQueueSize" keyword to daemon options option (OO) to + set the queue size parameter passed to listen(). You + will normally have to tweak your kernel to up this. + Strip spaces off of beginning of message-id before logging (in + case it was folded across lines). + Tweak compile flags in daemon.c -- there were some cases where + it wouldn't work without NETINET. + Change *file* mailer to output all the usual default headers + (From, Date, Message-Id). It gets used when sending + back error messages. + CONFIG: explicitly catch and diagnose list:; syntax in ruleset + zero -- this is not a valid recipient syntax according + to RFC 821. + CONFIG: add confMIME_FORMAT_ERRORS to send error messages in + MIME format. Defaults to on. + CONFIG: add SMTP_MAILER_FLAGS and UUCP_MAILER_FLAGS to augment + the flags for those mailers. + +6.56/6.27 93/05/01 + Fix problem that causes the fallback mail to postmaster + (case ESM_POSTMASTER in savemail()) to not look at + aliases (ugh). + Some more HPUX tweaking (compile flag hpux => __hpux so it + still works in ANSI mode). + Don't try to flock non-regular files when mailing to a file. + In particular, this was a problem if you tried to + send to /dev/null. + Fix a weird bug that can cause senders to be queued as + recipients if the name server is down when the mail + is initially sent. This hack just ignores sender + deletion (essentially, it sets the MeToo flag) if there + is a TEMPFAIL during processing of the sender address. + Obscure. + Fix a dangling else problem -- from Brian Bullen from University + of Stirling, UK. + Add the "b" mailer flag to force a blank line on the end of + messages. Some brilliant versions of /bin/mail insist + on this but do not add it themselves. + Add the "g" mailer flag to prevent user SMTP from sending + "MAIL From:<>". This is only intended to be a + transitional gesture, and should not be used if at + all possible. It appears that Berkeley and IDA + config files have always handled this properly; the + UK config kit apparently does not. + Don't lowercase and then capitalize header field names -- leave + them with original capitalization. Fixes from Bill + King of Allen-Bradley Company. + Further cleanup and improved reporting of error messages, + particularly conditions that cause messages to be + requeued for future delivery. + Tweak syslog priorities in some cases. + CONFIG: clean up route-addr on UUCP addresses. + +6.55/6.25 93/04/27 + HPUX 8.07 compatibility changes in getla() -- I had to make + these changes to get it to work at Berkeley, although + others seem to have been working before (???). + Various patches to XLA code. + Fix problem that causes setuid bit on files to be ignored from + SMTP or in queue runs. Problem noted by Jason Ornstein + of Under The Wire, Inc. + Fix problem that can cause CNAMEs to be ignored. + Generalize getmxrr to match local host in $=w instead of a + single name passed in. + Some cleanup from Eric Wassenaar: + Use FileMailer instead of ProgMailer in two places. + Eliminate duplicate 8th-bit stripping in commaize. + Fix a problem with mis-parsing of backslash escapes + under some circumstances. + NIS map fix (was always including trailing null character) + from Mike Glendinning of Ingres UK. + Add "a" mailer flag to try using ESMTP. It tries the EHLO + command and if that fails falls back to regular SMTP. + Also parses EHLO option keywords. If host supports + SIZE extension, this is added to the MAIL FROM: + command. + Extend "b" option to include a second value which is the + maximum message size this server is willing to accept. + For example, a value of "10/1000000" says that there + must be ten blocks free, and sendmail will reject + any message larger than one megabyte. + Some portability hooks for NeXT (this could be applicable + to Mach in general). You have to create an empty + file called "unistd.h" to get it to compile. + Adjust config values (MAXLINE, MAXATOM, and PSBUFSIZE) to + be more generous. + Add X400-Received: to the list of headers tagged with H_TRACE + in conf.c. From Bill King, Allen-Bradley Co. + +6.54/6.25 93/04/19 + Fix problem that caused redefinition of SMTP and QUEUE compile + flags. Pointed out by Jon Forrest of the Sequoia 2000 + project at Berkeley. + Properly handle \! hack -- it was treating host\!user as one + token (host!user) instead of three (host, !, user). + Fix from Eric Wassenaar of NIKHEF-H. + Fix compilation problem in getauthinfo() if IDENTPROTO is off. + Turn off DEFNAMES and DNSRCH when getting the hostsignature + (i.e., MX records) in level 1 configuration files; this + matches the old behaviour. From Motonori Nakamura of + Kyoto University. + Improve error message printing -- if sent through an alias, + error messages include the name of the alias in the + message. Unfortunately, in order to make this work + properly in queue runs, this changes the format of the + C line in the qf file. The relatively uselessness of + the previous information was pointed out to me by + Allan E Johannesen of WPI. + Add XLA compile flag to add hooks to Christophe Wolfhugel's + extended load average code. This is still in very early + form.

From Motonori Nakamura of Kyoto University. + More generalization of socket code for other protocols. + Shorten timeouts on reverse name lookups -- since they are done + during connection establishment, long timeouts here can + cause higher level timeouts. This mainly serves to accept + mail from hosts that do not have proper reverse (PTR) DNS + records set up. + Reset e_statmsg before each mailer invocation to avoid bogus + messages in the log. + Redefine $r, $s, and $_ in error envelopes so you don't get + incorrect cruft in the error message. Problem noted by + Motonori Nakamura of Kyoto University. + Fix a problem that can cause failure to return errors to Postmaster + in certain cases. From Motonori Nakamura. + Fix a problem that can cause some systems to give duplicate error + messages when a bad syntax address such as " $3 + the input "user@a.b.c" failed instead of being properly + rewritten as "user@a..c". + Neil also convinced me that it was correct that $~ should match + only one token -- the problem is that it's always possible + to add another token, so $~ matches far too eagerly. + +6.45/6.21 93/03/25 + Implement multi-word classes (properly!). + +6.44/6.21 93/03/25 + Add X-Authentication-Warning: headers to clue users into possible + attempts to forge mail. This is on the authwarnings + privacy flag, but is the default. Suggested by Bryan + Costales of ICSI. + Pass default units for convtime in so they can be more reasonable. + Allow config files to always add a new Comments: header (i.e., + they will be added even if an old one already exists). + Suggested by Bryan Costales of ICSI. + Allow config files to delete an existing Return-Path: header. + These should only be added at final delivery. Suggested + by Bryan Costales of ICSI. + Some debugging additions. Suggested by Bryan Costales of ICSI. + Clean up logging of Family 0 addresses. Noted by David Muir + Sharnoff and others. + Add a "dequote" map class. This allows config files to strip + quotes off of addresses. Note that this is not a builtin + map, just a class -- so you have to define the map + using the K line. + Fix a bug in the queueup() loop getting a locked tf where in + very odd cases it can fall off the bottom and core dump. + Of course, it was P{r Emanuelsson who found it.... + Open a new transcript when splitting an envelope. Problem found + by Allan E Johannesen of WPI. + Improved error output in endmailer if the mailer core dumps. + CONFIG: Fix typo in UUCP mailer definition. + CONFIG: Default several of the new options on: eight bit input, + privacy flags set to "authwarnings", and message warning + set to 4h. + CONFIG: Use dequote map. + +6.43/6.20 93/03/23 + Fix problem with assumption of an sa_len field in a generic + sockaddr -- it turns out that most vendors haven't + picked up this (very important) fix. + Change compilation flags for daemon code -- select one or both + of NETINET or NETISO, but don't ever set DAEMON manually. + CONFIG: add FEATURE(mailertable) to do IDA-style mailertables. + +6.42/6.19 93/03/19 + Use Postmaster as default fallback return address, not root. + POSIX changes for file descriptor handling. + Diagnose errors writing new queue file. + If you change the owner using an owner- alias, also change the + error mode to EM_MAIL so that errors don't get dropped + into an inappropriate directory. Problem noted by + Allan E Johannesen of WPI. + If you are su'ed to root, send email as who you really are, not + as root. From Brian Kantor of U.C. San Diego. + Allow warning messages to be sent after a configurable interval + has passed without delivery. The message is sent only + once per envelope. This changes the format of the qf + file to have an F line, and the format of the T option + to accept take the format "return/warn" (both intervals). + Don't force all local names to lower case -- this was left over + from the weird handling of case mapping on aliases. It + is now driven (as expected) by the "u" mailer flag. + Problem noted by P{r Emanuelsson. + Fix problem that caused headers on returned email to be trashed; + they were getting freed, but are still accessible via + BlankEnvelope. + Fix problem that caused bogus ids to be created on returned + mail. + Add support for ISO and other non-INET networking. This is by + no means finished yet. This does assume a lot of other + system support, like a version of gethostbyname that + returns non-AF_INET addresses. + CONFIG: change default on prog mailer to keep upper case in + user names (i.e., in the program command line). + CONFIG: strip trailing dots off of hosts in uucp mailer before + convert to bang format. + CONFIG: create new "relay" mailer for $R (LOCAL_RELAY) and $H + (MAIL_HUB) delivery that doesn't add local domain. Note + that this violates 821, but is probably "more correct" + for what we are trying to do. Problem pointed out by + Michael Graff of Iowa State. + +6.41/6.18 93/03/18 + Clean up unnecessary creates of queue ids (i.e., empty qf files) + when not needed, such as when starting up an SMTP + connection. + Fix problem where split envelopes aren't instantiated in the queue. + This is quite a serious bug. + Owner- aliases had problems with leading spaces causing a + premature delimitation. + +6.40/6.18 93/03/18 + Have ending 250 (after DATA) include the id; suggested by + Brian Kantor of UC San Diego. + Add logging on envelope splitting. + Change queue ids to have one more letter encoding the hour of + the day so that during a single day there is a greater + likelihood of uniqueness; requested by Brian Kantor. + +6.39/6.18 93/03/18 + Fix minor compile problem if LOCKF is defined. + Define size of tobuf in conf.h. Observed by Toshinari Takahashi + of Toshiba. + Restore e_sender -- this is equivalent to e_from.q_paddr without + decorations such as angle brackets and comments. + OSF/1 on Alpha changes from Allan E Johannesen of WPI. + CONFIG: fix typo in S3 for list syntax (;: => :;). Thanks to + Christopher Hoover for noting the problem. + +6.38/6.17 93/03/17 + Pass envelope to disconnect to avoid another use of CurEnv, which + can apparently end up being null at inopportune times. + Log "received from" as "relay=" for consistency (suggested by + John Gardiner Myers). + Fix major bug in header handling: if no From: line existed in + the header (so sendmail inserts one), and the sender is + an alias that has an owner, the From: line shows the + owner (as well as the envelope). Fixed by early binding + the headers (which will change debugging output). + HPUX portability patches from Michael J. Corrigan of UC San Diego. + Some attempts to adapt better to out of open file conditions. + Some changes to ctladdr handling in queue files. + +6.37/6.17 93/03/16 + MAJOR CHANGE: delete e_sender and e_returnpath (why are these + different from e_from?) and $< macro. + Log correct IP address in relay= field even if the connection + times out. + Log "received from [RESPONSE]" on EF_RESPONSE messages (from + John Gardiner Myers). + Fixes to SysExMsg logging (sometimes just got "message: %s" + instead of "message: error message"), noted by Eric + Wassenaar. Also reported by Motonori Nakamura. + Improvements to MX piggybacking code, from Motonori Nakamura. + Fix case where CurHostName points to an auto variable that has + been deallocated (from Motonori Nakamura). + Fix bug causing newlines to be included in aliases if option + "n" (check alias RHS) is set; bug noted by David Muir + Sharnoff. + Fix problem causing user names that should be mapped to lower + case to not be mapped if they are sent during a queue + run. This greatly simplifies the case mapping code. + Problem noted by Allan E Johannesen of WPI. + Don't do recipient address rewriting in buildaddr. This + improperly did recipient rewriting on sender addresses, + and just seems bogus in general -- but the change could + break some .cf files. + Pass TZ envariable to child processes for System V. + CONFIG: allow LOCAL_RULE_1 and LOCAL_RULE_2 if you want to + define those rulesets. + KNOWN PROBLEM: I have seen some problems on SunOS that causes + the User Data Base to give errors on some addresses. I + have tracked the problem back at least as far as 93.02.15 + (version 6.22). Running with debugging on makes it + go away, so I conclude that it is referencing uninitialized + stack data. I haven't been able to track this down yet. + +6.36/6.16 93/03/08 + Allow local mailer to specify $@host -- this lets you assign the + "foo" part of jgm+foo to $h for passing in to the local + mailer. + Additional debug printing in getcanonname (show query type). + Don't add the e_fromdomain on sender addresses -- this interacts + weirdly with the owner- code. + Improve delivery logging to not log obvious or meaningless stuff. + Include numeric IP address in Received: lines per RFC 1123 section + 5.2.8. + Fixed a bug in checking stat() return value if restrictmailq is + set. Also, check the entire group set instead of just the + primary group. Both from John Gardiner Myers. + Don't have usrerr automatically print errno, since this is often + misleading. + Use transienterror() in makeconnection after connect() fails and + in openmailer after execve() fails (from Eric Wassenaar). + Also moved transienterror() from util.c to conf.c. + Clean up from= logging on response messages. + Undo patch allowing prescan to return a null vector -- it breaks + too many things. + Config: FEATURE(notsticky) lets you use UDB for everything coming + in to the machine, even if it is specifically targetted + to this machine. Without it, UDB is bypassed if the user + name is fully qualified. + Config: fix another minor botch with <> (local mailer wasn't + mapping them properly). + +6.35/6.15 93/03/05 + Fix getrealhostname to return null if sinlen <= 0 -- this can + occur if stdin is a pipe. + Avoid infinite loop in getcanonname if name server return + NO_DATA (for example). + Config: avoid having C flag qualify list syntax and error syntax. + +6.34/6.14 93/03/05 + Fix logging in deliver to not pass too many parameters to Ultrix + versions of syslog. + Don't write the pid file until after the daemon has actually + opened and conditioned the connection. + Consider addresses "different" if their q_uids differ (so that + two users forwarding to the same program will be seen + as different, rather than the same). + Fix problem with bad parameters in main() -- they set ExitStat + but don't exit. + Fix null pointer references through RealHostName -- painfully + discovered by Allan E Johannesen of WPI. + Fix bug causing user@@localhost to core dump (yuch). + Config: don't put two @host.dom.ain on users in $=E in SMTP + mailer. Also, catch user@ (no host) in ruleset 0. + +6.33/6.13 93/03/03 + Config: add confCW_FILE as the name of the cw configuration file + (defaults to /etc/sendmail.cw). From P{r Emanuelsson. + Allow prescan to return a pointer to an empty list -- this is + not an error. Also, clean up error reporting to avoid + double errors (prescan reports once, then the caller + reports again). + Changes to avoid trusting T_ANY queries -- run them, but if you + don't get the info you expected, do T_A and T_MX queries + anyhow. This also fixes an oversight where _res.options + bits were being ignored. + If PRIV_NOVRFY is set, use 252 response code instead of 502 per + RFC 1123 section 5.2.3. It's not 100% clear that this + is correct, but it probably works better with stupid + mailers that do a VRFY and only check the first digit. + +6.32/6.12 93/03/02 + Fix uninitialized variable "protocol" in smtp code. + Include in sendmail.h -- move towards POSIX/ANSI. + Additional hooks for RFC 1427 (ESMTP SIZE extension). This + includes requiring that enoughspace() know the system + block size, which will undoubtedly break most ports. + Trace flag 19 in use for srvrsmtp.c. + Additional logging -- notably the sending mailer name. This + also changes the delivery logging to strict field=value + syntax. + Fix some problems with messages getting sent even to addresses + that had been marked bad -- from Eric Wassenaar. + More WIDE changes: accept host name inside [...] as non-MXed + host. This is intended ONLY for use inside firewalled + environments, where the MX points at the gateway. + Change .cf file conventions so that mapping for <> addresses + don't have an @ in them (to avoid confusing the C mailer + flag). Pointed out by Neil Rickert. + Config extensions for Sam Leffler's FlexFAX software. + +6.31/6.10 93/02/28 + Fix some more bugs in alias owner code -- there were some weird + cases where an error in a non-aliased name would override + the return info in an aliased name with an owner. + Changes from WIDE Project, forwarded to me by Motonori Nakamura: + Log actual delivery host (after MX et al); from + yasuhiro@dcl.co.jp. + Log daemon startup. + Deliver Postmaster copies without a body. + Better logging of SMTP senders. + Send all program email as daemon even when local. + As requested in various forms from many people, accept -qIstring + to limit queue runs to jobs with queue-id matching string. + Similarly for -qRstring for recipients, -qSstring for + senders. + Initial hooks for ESMTP support (see RFC 1425). + Fixed a syntax error in the UUCP mailer specification that caused + core dumps on startup. + Check for missing A= or P= arguments in mailer definitions. + +6.30/6.10 93/02/27 + Require FROZENCONFIG compilation flag to include frozen + configuration code. Frozen configuration is really + not a very good idea any more, particularly in shared + library environments. + Do better checking of errno after opens of :include: and .forward + files to defer delivery on network and other transient + errors. Suggestion from Craig Everhart. + Fix minor botch in read timeout macro processing. + Add FEATURE(nouucp) to config files for sites that know absolutely + nothing about UUCP. + Add built cf files to distribution tape and clarify how to build + them if you don't have the Berkeley make. + Some sizeof(long) portability changes for the Alpha, from Allan + E Johannesen. + Add "restrictmailq" privacy flag -- if set, only people in the same + group as your queue directory can print the queue. If you + set this, be sure you also restrict access to log files.... + Fix another bug in owner-list stuff that can cause data files to + be "lost". + Fix a bug with queue runs that cause forwards to yourself to go + into alias/forwarding loops. I'm still iffy about this + fix. + Fix from Eric Wassenaar for suppression of return message code. + +6.29/6.9 93/02/24 + Fix yet another problem in alias owner code -- put the wrong return + address on the enclosed return-to-sender letter. + +6.28/6.9 93/02/24 + Fix botch in alias owner code that caused it to not operate if the + error was detected locally. + +6.27/6.9 93/02/24 + M_LOCAL => M_LOCALMAILER to avoid conflict with Ultrix include + file . + Miscellaneous bug fixes from Eric Wassenaar: + sendmail -bv -t logs the from line even though in verify + mode only. + sendmail -v can go into queue mode if shouldqueue returns + TRUE. + Add route-addr pruning per RFC 1123 section 5.3.3. This can be + disabled using the "R" option. + Delete (always undocumented) -R flag (save original recipients); + there are ways to syslog(3) these now. + Clean up SMTP reply codes -- specify them as needed in the code, + instead of in conf.c -- this was needed during the NCP to + TCP transition, but seems silly now. This also changes + parameters to message and nmessage. + Have mailstats read the .cf file to find the sendmail.st file and + get text versions of mailer names. An initial version of + this code was provided by Tuominen Keijo (although the + comments indicate the good bits were written by "E.V."). + Add yet more System V compatibility hacks. + Fix bug in VRFY code (assumes everything must be a local user). + Allow specification of any of the hard-wired pathnames in the + Makefile. + Delete concept of "trusted users" -- this really didn't provide + any security anyway, and caused some problems. + Delete last vestige of support for the word "at" as an equivalent + to the character "@". + Propagate owner-foo alias information into the envelope sender. + Based on code from John Gardiner Myers. This is a major + semantic change -- beware! + Allow $@ on LHS to indicate "match zero" -- this is used to match + the null expression. + +6.26/6.8 93/02/21 + Don't "lose" queue runs. Very important fix from (who else?) + Eric Wassenaar. + Completely reset state on RSET command -- from Eric Wassenaar. + Send error messages and return receipts using an envelope sender + of <> regardless of the setting of $n. Rewriting rules + can undo this if they feel the necessity, as might be + needed for networks that don't understand the syntax. + This is permitted by RFC 821 section 3.6 and required by + RFC 1123 section 5.3.3. THIS REQUIRES VERSION 4 CONFIG + FILES because the rulesets must be able to parse <> + properly. + Don't ever send error messages to "<>" -- they will get sent to + the local postmaster or dumped in /usr/tmp/dead.letter + instead. Per RFC 1123 section 5.3.3. + Explicitly check for email to yourself as a dotted quad. You + have to call $[ [ ... ] $] to get this. + Up the message timeout to five days per RFC 1123 section 5.3.1.1. + Make all read timeouts individually configurable, as strongly + recommended by RFC 1123 section 5.3.2. + Use f_bavail (blocks available to regular users) instead of f_bfree + (blocks available to superuser) in free block checks. + Change $d macro to be the current time, not the origination time, + since this is consistent with how it is used now. + Generalization of enoughspace from Eric Wassenaar covering + SGI, Apollo, HPUX, Ultrix, and SunOS. + Ignore process group signals -- some front ends can do this if + you kill a window too quickly. From Eric Wassenaar. + Change umask to 022. + +6.25/6.8 93/02/20 + Close all cached connections before calling mailers and after + forking for delivery (caused double closes which resulted + in false errors). + Add FEATURE(redirect) in config files -- this allows you to alias + old addresses to a pointer to the new address that will + give a 551 error message, but not deliver the mail. + Some code changes to make the 551 errors look pretty. + Names of M4 program paths in config files have changed -- they + are all XXX_MAILER_PATH now, to match XXX_MAILER_FLAGS. + Fix a bug in the QSELFREF code having to do with empty .forward + files, reported by Eric Wassenaar. + Add option "p" (privacy flags); this allows you to tune how + picky the SMTP server will be. This also adds the + confPRIVACY_FLAGS M4 macro in the config files. + Add option "b" (minimum blocks free). If there are fewer than + this number of blocks free on the filesystem containing + the queue directory, the SMTP MAIL command will return + a 452 response and ask you to try again later. This + also adds the confMIN_FREE_BLOCKS M4 macro in the config + files. + Made VRFY just verify (doesn't expand aliases and .forward files); + EXPN does full expansion. RCPT in queue-only mode also + doesn't chase aliases and .forward. + +6.24/6.7 93/02/19 + Increase the number of domain search entries in domain.c to allow + for the extra "" entry indicating the root domain. + Reported by Motonori Nakamura of Kyoto U. + Add a "SMART_HOST" in the configs for UUCP-connected sites that + want to forward all mail with extra "@"s to that site. + Also allows SMART_HOST, LOCAL_RELAY, and MAIL_HUB to + be specified as ``mailer:hostname'' to use an alternate + mailer. + Clarified and updated some wording in the Operations Guide. + Add the "c" mailer flag -- this suppresses all comment parts of + addresses (requested by John Curran of NEARnet). + Have -v print prompts in -bt mode even if stdin is not a terminal + (default behaviour is to be silent if not reading from + a terminal). Suggested by Bryan Costales, ICSI. + Move the metacharacters from C0 space (\001-\037) into C1 space + (\201-\237). This also fixes a bunch of potential bugs + with G1 characters (\240-\276) in headers relating to + negative numbers passed to isspace() et al. + Add YP_LAST_MODIFIED and YP_MASTER_NAME to DBM version of alias + database if YPCOMPAT is #defined. Enhancement from + Takahiro Kanbe of Fuji Xerox Information Systems Co., Ltd. + Add "list" Precedence (-30); this can be used with old sendmails + which will map to precedence 0 (which will return error + messages). Suggested by Stephen R. van den Berg. + Many bug fixes from Eric Wassenaar of the National Institute for + Nuclear and High-Energy Physics, Amsterdam: + Clear timeouts properly on open failures in include(). + Don't dereference through NULL if no home directory found. + Re-establish SIGCHLD signal on System 5 in reapchild(). + Avoid NULL pointer reference on -pFOO flag. + Properly handle backslash escapes in comments. + Correctly check reply status on SMTP NOOP command. + Properly save SMTP error message if peer gives + "Service Shutting Down" message. + Avoid writing to the transcript if it couldn't be opened. + Signal errors in SMTP children to parent properly. + Handle self references in a list more globally (include a + QSELFREF bit in the address flags). This enhancement + was suggested by Eric Wassenaar. + Use initgroups() in hpux, even though it's System-V based. The + HASINITGROUPS compile flag can set this on other systems. + This HPUX behaviour was pointed out by Eric Wassenaar. + +6.23/6.6 93/02/16 + Clean up handling of LogLevel to make it easier to figure out + what's on what level. + Change log levels to have some consistency: + 1 serious system failures, security problems + 2 lost communications, protocol failures + 3 other serious failures + 4 minor errors + 5 message collection + 6 vrfy logging, creation of return-to-sender + 7 delivery failures + 8 delivery successes + 9 delivery tempfails (queue ups) + 10 database expansion + >64 debugging + Allow IDA-style separated processing on S= and R= in Mailer + definition lines.

First, the network +has become more consistent -- for example, at this point, everyone +on the internet is supposed to be running a name server, so hacks to +handle NIC-registered hosts can go away. Second, I assumed that a +subdomain would be running SMTP internally -- UUCP is presumed to be +a long-haul protocol. I realize that this is not universal, but it +does describe the vast majority of sites with which I am familiar, +including those outside the US. + +Of course, the downside of this is that if you do live in a weird +world, things are going to get weirder for you. I'm sorry about that, +but at the time we at Berkeley had a problem, and it seemed like the +right thing to do. + +This package requires a post-V7 version of m4; if you are running the +4.2bsd, SysV.2, or 7th Edition version, I suggest finding a friend with +a newer version. You can m4-expand on their system, then run locally. +SunOS's /usr/5bin/m4 or BSD-Net/2's m4 both work. GNU m4 version 1.1 +or later also works. Unfortunately, I'm told that the M4 on BSDI 1.0 +doesn't work -- you'll have to use a Net/2 or GNU version. GNU m4 is +available from ftp://ftp.gnu.org/pub/gnu/m4-1.4.tar.gz (check for +the latest version). EXCEPTIONS: DEC's m4 on Digital UNIX 4.x is broken +(3.x is fine). Use GNU m4 on this platform. + +IF YOU DON'T HAVE A BERKELEY MAKE, don't despair! Just run +"m4 ../m4/cf.m4 foo.mc > foo.cf" -- that should be all you need. +There is also a fairly crude (but functional) Makefile.dist that works +on the old version of make. + +To get started, you may want to look at tcpproto.mc (for TCP-only +sites), uucpproto.mc (for UUCP-only sites), and clientproto.mc (for +clusters of clients using a single mail host). Others are versions +that we use at Berkeley, although not all are in current use. For +example, ucbvax has gone away, but I've left ucbvax.mc in because +it demonstrates some interesting techniques. + +I'm not pretending that this README describes everything that these +configuration files can do; clever people can probably tweak them +to great effect. But it should get you started. + +******************************************************************* +*** BE SURE YOU CUSTOMIZE THESE FILES! They have some *** +*** Berkeley-specific assumptions built in, such as the name *** +*** of our UUCP-relay.

They must be run through "m4" to produce a ".cf" file. +You must pre-load "cf.m4": + + m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf + +where ${CFDIR} is the root of the cf directory and config.mc is the +name of your configuration file. If you are running a version of M4 +that understands the __file__ builtin (versions of GNU m4 >= 0.75 do +this, but the versions distributed with 4.4BSD and derivatives do not) +or the -I flag (ditto), then ${CFDIR} can be in an arbitrary directory. +For "traditional" versions, ${CFDIR} ***MUST*** be "..", or you MUST +use -D_CF_DIR_=/path/to/cf/dir/ -- note the trailing slash! For example: + + m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 config.mc > config.cf + +Let's examine a typical .mc file: + + divert(-1) + # + # Copyright (c) 1998 Sendmail, Inc.

We use SCCS; you could use RCS, something else, or +omit it completely. This is not the same as the version id included +in SMTP greeting messages -- this is defined in m4/version.m4. + + OSTYPE(hpux9)dnl + +You must specify an OSTYPE to properly configure things such as the +pathname of the help and status files, the flags needed for the local +mailer, and other important things.

The +local mailer is always included automatically. Beware: MAILER +declarations should always be at the end of the configuration file, +and MAILER(smtp) should always precede MAILER(uucp). The general +rules are that the order should be: + + VERSIONID + OSTYPE + DOMAIN + FEATURE + local macro definitions + MAILER + LOCAL_RULESET_* + + ++----------------------------+ +| A BRIEF INTRODUCTION TO M4 | ++----------------------------+ + +Sendmail uses the M4 macro processor to ``compile'' the configuration +files. The most important thing to know is that M4 is stream-based, +that is, it doesn't understand about lines. For this reason, in some +places you may see the word ``dnl'', which stands for ``delete +through newline''; essentially, it deletes all characters starting +at the ``dnl'' up to and including the next newline character. In +most cases sendmail uses this only to avoid lots of unnecessary +blank lines in the output. + +Other important directives are define(A, B) which defines the macro +``A'' to have value ``B''. Macros are expanded as they are read, so +one normally quotes both values to prevent expansion. For example, + + define(`SMART_HOST', `smart.foo.com') + +One word of warning: M4 macros are expanded even in lines that appear +to be comments. For example, if you have + + # See FEATURE(foo) above + +it will not do what you expect, because the FEATURE(foo) will be +expanded. This also applies to + + # And then define the $X macro to be the return address + +because ``define'' is an M4 keyword. If you want to use them, surround +them with directed quotes, `like this'. + ++----------------+ +| FILE LOCATIONS | ++----------------+ + +sendmail 8.9 has introduced a new configuration directory for sendmail +related files, /etc/mail. The new files available for sendmail 8.9 -- +the class 'R' /etc/mail/relay-domains and the access database +/etc/mail/access -- take advantage of this new directory. 8.9 will +serve as a transition release. Beginning with 8.10, all of the files +will use this directory by default. + ++--------+ +| OSTYPE | ++--------+ + +You MUST define an operating system environment, or the configuration +file build will puke. There are several environments available; look +at the "ostype" directory for the current list. This macro changes +things like the location of the alias file and queue directory. Some +of these files are identical to one another. + +It is IMPERATIVE that the OSTYPE occur before any MAILER definitions. +In general, the OSTYPE macro should go immediately after any version +information, and MAILER definitions should always go last. + +Operating system definitions are usually easy to write. They may define +the following variables (everything defaults, so an ostype file may be +empty). Unfortunately, the list of configuration-supported systems is +not as broad as the list of source-supported systems, since many of +the source contributors do not include corresponding ostype files. + +ALIAS_FILE [/etc/aliases] The location of the text version + of the alias file(s). It can be a comma-separated + list of names (but be sure you quote values with + commas in them -- for example, use + define(`ALIAS_FILE', `a,b') + to get "a" and "b" both listed as alias files; + otherwise the define() primitive only sees "a"). +HELP_FILE [/usr/lib/sendmail.hf] The name of the file + containing information printed in response to + the SMTP HELP command. +QUEUE_DIR [/var/spool/mqueue] The directory containing + queue files. +STATUS_FILE [/etc/sendmail.st] The file containing status + information. +LOCAL_MAILER_PATH [/bin/mail] The program used to deliver local mail. +LOCAL_MAILER_FLAGS [rmn9] The flags used by the local mailer.

Default + flags are `DFMhuU' (and `m' for uucp-new mailer, + minus `U' for uucp-dom mailer). +UUCP_MAILER_ARGS [uux - -r -z -a$g -gC $h!rmail ($u)] The arguments + passed to the UUCP mailer. +UUCP_MAILER_MAX [100000] The maximum size message accepted for + transmission by the UUCP mailers. +UUCP_MAILER_CHARSET [undefined] If defined, messages containing 8-bit data + that ARRIVE from an address that resolves to one of + the UUCP mailers and which are converted to MIME will + be labeled with this character set. +FAX_MAILER_PATH [/usr/local/lib/fax/mailfax] The program used to + submit FAX messages. +FAX_MAILER_ARGS [mailfax $u $h $f] The arguments passed to the FAX + mailer. +FAX_MAILER_MAX [100000] The maximum size message accepted for + transmission by FAX. +POP_MAILER_PATH [/usr/lib/mh/spop] The pathname of the POP mailer. +POP_MAILER_FLAGS [Penu] Flags added to POP mailer.

This is also used by FEATURE(local_procmail). +PROCMAIL_MAILER_FLAGS [SPhnu9] Flags added to Procmail mailer. Flags + ``DFM'' are always set. This is NOT used by + FEATURE(local_procmail); tweak LOCAL_MAILER_FLAGS + instead. +PROCMAIL_MAILER_ARGS [procmail -Y -m $h $f $u] The arguments passed to + the Procmail mailer. This is NOT used by + FEATURE(local_procmail); tweak LOCAL_MAILER_ARGS + instead. +PROCMAIL_MAILER_MAX [undefined] If set, the maximum size message that + will be accepted by the procmail mailer. +MAIL11_MAILER_PATH [/usr/etc/mail11] The path to the mail11 mailer. +MAIL11_MAILER_FLAGS [nsFx] Flags for the mail11 mailer. +MAIL11_MAILER_ARGS [mail11 $g $x $h $u] Arguments passed to the mail11 + mailer. +PH_MAILER_PATH [/usr/local/etc/phquery] The path to the phquery + program. +PH_MAILER_FLAGS [ehmu] Flags for the phquery mailer. +PH_MAILER_ARGS [phquery -- $u] -- arguments to the phquery mailer. +CYRUS_MAILER_FLAGS [A5@/:|] The flags used by the cyrus mailer.

For example, our Berkeley +domain file includes definitions for several internal distinguished +hosts: + +UUCP_RELAY The host that will accept UUCP-addressed email. + If not defined, all UUCP sites must be directly + connected. +BITNET_RELAY The host that will accept BITNET-addressed email. + If not defined, the .BITNET pseudo-domain won't work. +DECNET_RELAY The host that will accept DECNET-addressed email. + If not defined, the .DECNET pseudo-domain and addresses + of the form node::user will not work. +FAX_RELAY The host that will accept mail to the .FAX pseudo-domain. + The "fax" mailer overrides this value. +LOCAL_RELAY DEPRECATED. The site that will handle unqualified + names -- that is, names with out an @domain extension. + If not set, they are assumed to belong on this machine. + This allows you to have a central site to store a + company- or department-wide alias database. This + only works at small sites, and only with some user + agents. +LUSER_RELAY The site that will handle lusers -- that is, apparently + local names that aren't local accounts or aliases. + +Any of these can be either ``mailer:hostname'' (in which case the +mailer is the internal mailer name, such as ``uucp-new'' and the hostname +is the name of the host as appropriate for that mailer) or just a +``hostname'', in which case a default mailer type (usually ``relay'', +a variant on SMTP) is used. WARNING: if you have a wildcard MX +record matching your domain, you probably want to define these to +have a trailing dot so that you won't get the mail diverted back +to yourself. + +The domain file can also be used to define a domain name, if needed +(using "DD") and set certain site-wide features. If all hosts +at your site masquerade behind one email name, you could also use +MASQUERADE_AS here. + +You do not have to define a domain -- in particular, if you are a +single machine sitting off somewhere, it is probably more work than +it's worth. This is just a mechanism for combining "domain dependent +knowledge" into one place. + ++---------+ +| MAILERS | ++---------+ + +There are fewer mailers supported in this version than the previous +version, owing mostly to a simpler world. As a general rule, put the +MAILER definitions last in your .mc file, and always put MAILER(smtp) +before MAILER(uucp) -- several features and definitions will modify +the definition of mailers, and the smtp mailer modifies the UUCP +mailer. + +local The local and prog mailers. You will almost always + need these; the only exception is if you relay ALL + your mail to another site. This mailer is included + automatically. + +smtp The Simple Mail Transport Protocol mailer. This does + not hide hosts behind a gateway or another other + such hack; it assumes a world where everyone is + running the name server. This file actually defines + four mailers: "smtp" for regular (old-style) SMTP to + other servers, "esmtp" for extended SMTP to other + servers, "smtp8" to do SMTP to other servers without + converting 8-bit data to MIME (essentially, this is + your statement that you know the other end is 8-bit + clean even if it doesn't say so), and "relay" for + transmission to our RELAY_HOST, LUSER_RELAY, or + MAILER_HUB. + +uucp The Unix-to-Unix Copy Program mailer. Actually, this + defines two mailers, "uucp-old" (a.k.a. "uucp") and + "uucp-new" (a.k.a. "suucp"). The latter is for when you + know that the UUCP mailer at the other end can handle + multiple recipients in one transfer. If the smtp mailer + is also included in your configuration, two other mailers + ("uucp-dom" and "uucp-uudom") are also defined [warning: + you MUST specify MAILER(smtp) before MAILER(uucp)]. When you + include the uucp mailer, sendmail looks for all names in + the $=U class and sends them to the uucp-old mailer; all + names in the $=Y class are sent to uucp-new; and all + names in the $=Z class are sent to uucp-uudom. Note that + this is a function of what version of rmail runs on + the receiving end, and hence may be out of your control. + See the section below describing UUCP mailers in more + detail. + +usenet Usenet (network news) delivery. If this is specified, + an extra rule is added to ruleset 0 that forwards all + local email for users named ``group.usenet'' to the + ``inews'' program. Note that this works for all groups, + and may be considered a security problem. + +fax Facsimile transmission. This is experimental and based + on Sam Leffler's HylaFAX software. For more information, + see http://www.vix.com/hylafax/. + +pop Post Office Protocol. + +procmail An interface to procmail (does not come with sendmail). + This is designed to be used in mailertables. For example, + a common question is "how do I forward all mail for a given + domain to a single person?". If you have this mailer + defined, you could set up a mailertable reading: + + host.com procmail:/etc/procmailrcs/host.com + + with the file /etc/procmailrcs/host.com reading: + + :0 # forward mail for host.com + ! -oi -f $1 person@other.host + + This would arrange for (anything)@host.com to be sent + to person@other.host. Within the procmail script, $1 is + the name of the sender and $2 is the name of the recipient. + If you use this with FEATURE(local_procmail), the FEATURE + should be listed first. + +mail11 The DECnet mail11 mailer, useful only if you have the mail11 + program from gatekeeper.dec.com:/pub/DEC/gwtools (and + DECnet, of course). This is for Phase IV DECnet support; + if you have Phase V at your site you may have additional + problems. + +phquery The phquery program. This is somewhat counterintuitively + referenced as the "ph" mailer internally. It can be used + to do CCSO name server lookups. The phquery program, which + this mailer uses, is distributed with the ph client. + +cyrus The cyrus and cyrusbb mailers. The cyrus mailer delivers to + a local cyrus user. this mailer can make use of the + "user+detail@local.host" syntax; it will deliver the mail to + the user's "detail" mailbox if the mailbox's ACL permits. + The cyrusbb mailer delivers to a system-wide cyrus mailbox + if the mailbox's ACL permits. + + +The local mailer accepts addresses of the form "user+detail", where +the "+detail" is not used for mailbox matching but is available +to certain local mail programs (in particular, see FEATURE(local_procmail)). +For example, "eric", "eric+sendmail", and "eric+sww" all indicate +the same user, but additional arguments , "sendmail", and "sww" +may be provided for use in sorting mail. + + ++----------+ +| FEATURES | ++----------+ + +Special features can be requested using the "FEATURE" macro. For +example, the .mc line: + + FEATURE(use_cw_file) + +tells sendmail that you want to have it read an /etc/sendmail.cw +file to get values for class $=w. The FEATURE may contain a single +optional parameter -- for example: + + FEATURE(mailertable, dbm /usr/lib/mailertable) + +The default database map type for the table features can be set with + + define(`DATABASE_MAP_TYPE', `dbm') + +which would set it to use ndbm databases. The default is the Berkeley DB +hash database format. Note that you must still declare a database map type +if you specify an argument to a FEATURE. DATABASE_MAP_TYPE is only used +if no argument is given for the FEATURE. + +Available features are: + +use_cw_file Read the file /etc/sendmail.cw file to get alternate + names for this host. This might be used if you were + on a host that MXed for a dynamic set of other + hosts. If the set is static, just including the line + "Cw ..." (where the names are fully + qualified domain names) is probably superior. + The actual filename can be overridden by redefining + confCW_FILE. + +use_ct_file Read the file /etc/sendmail.ct file to get the names + of users that will be ``trusted'', that is, able to + set their envelope from address using -f without + generating a warning message. + The actual filename can be overridden by redefining + confCT_FILE. + +redirect Reject all mail addressed to "address.REDIRECT" with + a ``551 User not local; please try
'' message. + If this is set, you can alias people who have left + to their new address with ".REDIRECT" appended. + +nouucp Don't do anything special with UUCP addresses at all. + +nocanonify Don't pass addresses to $[ ... $] for canonification. + This would generally only be used by sites that only + act as mail gateways or which have user agents that do + full canonification themselves. You may also want to + use "define(`confBIND_OPTS',`-DNSRCH -DEFNAMES')" to + turn off the usual resolver options that do a similar + thing. + +stickyhost If set, email sent to "user@local.host" are marked + as "sticky" -- that is, the local addresses aren't + matched against UDB and don't go through ruleset 5. + This is used if you want a set up where "user" is + not necessarily the same as "user@local.host", e.g., + to make a distinct domain-wide namespace. Prior to + 8.7 this was the default, and notsticky was used to + turn this off. + +mailertable Include a "mailer table" which can be used to override + routing for particular domains. The argument of the + FEATURE may be the key definition. If none is specified, + the definition used is: + hash -o /etc/mailertable + Keys in this database are fully qualified domain names + or partial domains preceded by a dot -- for example, + "vangogh.CS.Berkeley.EDU" or ".CS.Berkeley.EDU". + Values must be of the form: + mailer:domain + where "mailer" is the internal mailer name, and "domain" + is where to send the message. These maps are not + reflected into the message header. As a special case, + the forms: + local:user + will forward to the indicated user using the local mailer, + local: + will forward to the original user in the e-mail address + using the local mailer, and + error:code message + will give an error message with the indicated code and + message. + +domaintable Include a "domain table" which can be used to provide + domain name mapping. Use of this should really be + limited to your own domains. It may be useful if you + change names (e.g., your company changes names from + oldname.com to newname.com). The argument of the + FEATURE may be the key definition. If none is specified, + the definition used is: + hash -o /etc/domaintable + The key in this table is the domain name; the value is + the new (fully qualified) domain. Anything in the + domaintable is reflected into headers; that is, this + is done in ruleset 3. + +bitdomain Look up bitnet hosts in a table to try to turn them into + internet addresses. The table can be built using the + bitdomain program contributed by John Gardiner Myers. + The argument of the FEATURE may be the key definition; if + none is specified, the definition used is: + hash -o /etc/bitdomain.db + Keys are the bitnet hostname; values are the corresponding + internet hostname. + +uucpdomain Similar feature for UUCP hosts. The default map definition + is: + hash -o /etc/uudomain.db + At the moment there is no automagic tool to build this + database. + +always_add_domain + Include the local host domain even on locally delivered + mail. Normally it is not added on unqualified names. + However, if you use a shared message store but do not use + the same user name space everywhere, you may need the host + name on local names. + +allmasquerade If masquerading is enabled (using MASQUERADE_AS), this + feature will cause recipient addresses to also masquerade + as being from the masquerade host. Normally they get + the local hostname. Although this may be right for + ordinary users, it can break local aliases. For example, + if you send to "localalias", the originating sendmail will + find that alias and send to all members, but send the + message with "To: localalias@masqueradehost". Since that + alias likely does not exist, replies will fail. Use this + feature ONLY if you can guarantee that the ENTIRE + namespace on your masquerade host supersets all the + local entries. + +limited_masquerade + Normally, any hosts listed in $=w are masqueraded. If this + feature is given, only the hosts listed in $=M are masqueraded. + This is useful if you have several domains with disjoint + namespaces hosted on the same machine. + +masquerade_entire_domain + If masquerading is enabled (using MASQUERADE_AS) and + MASQUERADE_DOMAIN (see below) is set, this feature will + cause addresses to be rewritten such that the masquerading + domains are actually entire domains to be hidden. All + hosts within the masquerading domains will be rewritten + to the masquerade name (used in MASQUERADE_AS). For example, + if you have: + + MASQUERADE_AS(masq.com) + MASQUERADE_DOMAIN(foo.org) + MASQUERADE_DOMAIN(bar.com) + + then *foo.org and *bar.com are converted to masq.com. Without + this feature, only foo.org and bar.com are masqueraded. + + NOTE: only domains within your jurisdiction and + current hierarchy should be masqueraded using this. + +genericstable This feature will cause certain addresses originating locally + (i.e. that are unqualified) or a domain listed in $=G to be + looked up in a map and turned into another ("generic") form, + which can change both the domain name and the user name. This + is similar to the userdb functionality. The same types of + addresses as for masquerading are looked up, i.e. only header + sender addresses unless the allmasquerade and/or + masquerade_envelope features are given. Qualified addresses + must have the domain part in the list of names given by the + by the macros GENERICS_DOMAIN or GENERICS_DOMAIN_FILE + (analogously to MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE, + see below). + + The argument of FEATURE(genericstable) may be the map + definition; the default map definition is: + + hash -o /etc/genericstable + + The key for this table is either the full address or the + unqualified username (the former is tried first); the + value is the new user address. If the new user address does + not include a domain, it will be qualified in the standard + manner, i.e. using $j or the masquerade name. Note that the + address being looked up must be fully qualified. For local + mail, it is necessary to use FEATURE(always_add_domain) for + the addresses to be qualified. + +virtusertable A domain-specific form of aliasing, allowing multiple + virtual domains to be hosted on one machine. For example, + if the virtuser table contained: + + info@foo.com foo-info + info@bar.com bar-info + @baz.org jane@elsewhere.net + + then mail addressed to info@foo.com will be sent to the + address foo-info, mail addressed to info@bar.com will be + delivered to bar-info, and mail addressed to anyone at + baz.org will be sent to jane@elsewhere.net. The username + from the original address is passed as %1 allowing: + + @foo.org %1@elsewhere.com + + meaning someone@foo.org will be sent to someone@elsewhere.com. + + All the host names on the left hand side (foo.com, bar.com, + and baz.org) must be in $=w. The default map definition is: + + hash -o /etc/virtusertable + + A new definition can be specified as the second argument of + the FEATURE macro, such as + + FEATURE(virtusertable, dbm -o /etc/mail/virtusers) + +nodns We aren't running DNS at our site (for example, + we are UUCP-only connected). It's hard to consider + this a "feature", but hey, it had to go somewhere. + Actually, as of 8.7 this is a no-op -- remove "dns" from + the hosts service switch entry instead. + +nullclient This is a special case -- it creates a stripped down + configuration file containing nothing but support for + forwarding all mail to a central hub via a local + SMTP-based network. The argument is the name of that + hub. + + The only other feature that should be used in conjunction + with this one is "nocanonify" (this causes addresses to + be sent unqualified via the SMTP connection; normally + they are qualified with the masquerade name, which + defaults to the name of the hub machine). No mailers + should be defined. No aliasing or forwarding is done. + +local_lmtp Use an LMTP capable local mailer. The argument to this + feature is the pathname of an LMTP capable mailer. By + default, mail.local is used. This is expected to be the + mail.local which came with the 8.9 distribution which is + LMTP capable. The path to mail.local is set by the + confEBINDIR m4 variable -- making the default + LOCAL_MAILER_PATH /usr/libexec/mail.local. + +local_procmail Use procmail as the local mailer. This mailer can + make use of the "user+indicator@local.host" syntax; + normally the +indicator is just tossed, but by default + it is passed as the -a argument to procmail. The + argument to this feature is the pathname of procmail, + which defaults to PROCMAIL_MAILER_PATH. Note that this + does NOT use PROCMAIL_MAILER_FLAGS or PROCMAIL_MAILER_ARGS + for the local mailer; tweak LOCAL_MAILER_FLAGS and + LOCAL_MAILER_ARGS instead. + +bestmx_is_local Accept mail as though locally addressed for any host that + lists us as the best possible MX record. This generates + additional DNS traffic, but should be OK for low to + medium traffic hosts. The argument may be a set of + domains, which will limit the feature to only apply to + these domains -- this will reduce unnecessary DNS + traffic. THIS FEATURE IS FUNDAMENTALLY INCOMPATIBLE WITH + WILDCARD MX RECORDS!!! If you have a wildcard MX record + that matches your domain, you cannot use this feature. + +smrsh Use the SendMail Restricted SHell (smrsh) provided + with the distribution instead of /bin/sh for mailing + to programs. This improves the ability of the local + system administrator to control what gets run via + e-mail. If an argument is provided it is used as the + pathname to smrsh; otherwise, the path defined by + confEBINDIR is used for the smrsh binary -- by default, + /usr/libexec/smrsh is assumed. + +promiscuous_relay + By default, the sendmail configuration files do not permit + mail relaying (that is, accepting mail from outside your + domain and sending it to another host outside your domain). + This option sets your site to allow mail relaying from any + site to any site. In general, it is better to control the + relaying more carefully with the access db and the 'R' + class ($=R). Domains can be added to class 'R' by the + macros RELAY_DOMAIN or RELAY_DOMAIN_FILE (analogously to + MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE, see below). + +relay_entire_domain + By default, only hosts listed as RELAY in the access db + will be allowed to relay. This option also allows any + host in your domain as defined by the 'm' class ($=m). + +relay_hosts_only + By default, names that are listed as RELAY in the access + db and class 'R' ($=R) are domain names, not host names. + For example, if you specify ``foo.com'', then mail to or + from foo.com, abc.foo.com, or a.very.deep.domain.foo.com + will all be accepted for relaying. This feature changes + the behaviour to lookup individual host names only. + +relay_based_on_MX + Turns on the ability to allow relaying based on the MX + records of the host portion of an incoming recipient. See + description below for more information before using this + feature. + +relay_local_from + Allows relaying if the domain portion of the mail sender + is a local host. This should only be used if absolutely + necessary as it opens a window for spammers. + +accept_unqualified_senders + Normally, MAIL FROM: commands in the SMTP session will be + refused if the connection is a network connection and the + sender address does not include a domain name. If your + setup sends local mail unqualified (i.e. MAIL FROM: ), + you will need to use this feature to accept unqualified + sender addresses. + +accept_unresolvable_domains + Normally, MAIL FROM: commands in the SMTP session will be + refused if the host part of the argument to MAIL FROM: cannot + be located in the host name service (e.g., DNS). If you are + inside a firewall that has only a limited view of the + Internet host name space, this could cause problems. In this + case you probably want to use this feature to accept all + domains on input, even if they are unresolvable. + +access_db Turns on the access database feature. The access db gives + you the ability to allow or refuse to accept mail from + specified domains for administrative reasons. By default, + the access database specification is + ``hash -o /etc/mail/access''. The format of the + database is described below. + +blacklist_recipients + Turns on the ability to block incoming mail for certain + recipient usernames, hostnames, or addresses. For + example, you can block incoming mail to user nobody, + host foo.mydomain.com, or guest@bar.mydomain.com. + These specifications are put in the access db as + described below. + +rbl Turns on rejection of hosts found in the Realtime Blackhole + List. If an argument is provided it is used as the + name sever to contact; otherwise, the main RBL server at + rbl.maps.vix.com is used. For details, see + http://maps.vix.com/rbl/. + +loose_relay_check + Normally, if a recipient using % addressing is used, e.g. + user%site@othersite, and othersite is in class 'R', the + check_rcpt ruleset will strip @othersite and recheck + user@site for relaying. This feature changes that + behavior. It should not be needed for most installations. + + ++-------+ +| HACKS | ++-------+ + +Some things just can't be called features. To make this clear, +they go in the hack subdirectory and are referenced using the HACK +macro. These will tend to be site-dependent. The release +includes the Berkeley-dependent "cssubdomain" hack (that makes +sendmail accept local names in either Berkeley.EDU or CS.Berkeley.EDU; +this is intended as a short-term aid while we move hosts into +subdomains. + + ++--------------------+ +| SITE CONFIGURATION | ++--------------------+ + + ***************************************************** + * This section is really obsolete, and is preserved * + * only for back compatibility. You should plan on * + * using mailertables for new installations. In * + * particular, it doesn't work for the newer forms * + * of UUCP mailers, such as uucp-uudom. * + ***************************************************** + +Complex sites will need more local configuration information, such as +lists of UUCP hosts they speak with directly. This can get a bit more +tricky. For an example of a "complex" site, see cf/ucbvax.mc. + +If your host is known by several different names, you need to augment +the $=w class. This is a list of names by which you are known, and +anything sent to an address using a host name in this list will be +treated as local mail. You can do this in two ways: either create +the file /etc/sendmail.cw containing a list of your aliases (one per +line), and use ``FEATURE(use_cw_file)'' in the .mc file, or add the +line: + + Cw alias.host.name + +at the end of that file. See the ``vangogh.mc'' file for an example. +Be sure you use the fully-qualified name of the host, rather than a +short name. + +The SITECONFIG macro allows you to indirectly reference site-dependent +configuration information stored in the siteconfig subdirectory. For +example, the line + + SITECONFIG(uucp.ucbvax, ucbvax, U) + +reads the file uucp.ucbvax for local connection information. The +second parameter is the local name (in this case just "ucbvax" since +it is locally connected, and hence a UUCP hostname). The third +parameter is the name of both a macro to store the local name (in +this case, $U) and the name of the class (e.g., $=U) in which to store +the host information read from the file. Another SITECONFIG line reads + + SITECONFIG(uucp.ucbarpa, ucbarpa.Berkeley.EDU, W) + +This says that the file uucp.ucbarpa contains the list of UUCP sites +connected to ucbarpa.Berkeley.EDU. The $=W class will be used to +store this list, and $W is defined to be ucbarpa.Berkeley.EDU, that +is, the name of the relay to which the hosts listed in uucp.ucbarpa +are connected. [The machine ucbarpa is gone now, but I've left +this out-of-date configuration file around to demonstrate how you +might do this.] + +Note that the case of SITECONFIG with a third parameter of ``U'' is +special; the second parameter is assumed to be the UUCP name of the +local site, rather than the name of a remote site, and the UUCP name +is entered into $=w (the list of local hostnames) as $U.UUCP. + +The siteconfig file (e.g., siteconfig/uucp.ucbvax.m4) contains nothing +more than a sequence of SITE macros describing connectivity. For +example: + + SITE(cnmat) + SITE(sgi olympus) + +The second example demonstrates that you can use two names on the +same line; these are usually aliases for the same host (or are at +least in the same company). + + ++--------------------+ +| USING UUCP MAILERS | ++--------------------+ + +It's hard to get UUCP mailers right because of the extremely ad hoc +nature of UUCP addressing. These config files are really designed +for domain-based addressing, even for UUCP sites. + +There are four UUCP mailers available. The choice of which one to +use is partly a matter of local preferences and what is running at +the other end of your UUCP connection. Unlike good protocols that +define what will go over the wire, UUCP uses the policy that you +should do what is right for the other end; if they change, you have +to change. This makes it hard to do the right thing, and discourages +people from updating their software. In general, if you can avoid +UUCP, please do. + +The major choice is whether to go for a domainized scheme or a +non-domainized scheme. This depends entirely on what the other +end will recognize. If at all possible, you should encourage the +other end to go to a domain-based system -- non-domainized addresses +don't work entirely properly. + +The four mailers are: + + uucp-old (obsolete name: "uucp") + This is the oldest, the worst (but the closest to UUCP) way of + sending messages accros UUCP connections. It does bangify + everything and prepends $U (your UUCP name) to the sender's + address (which can already be a bang path itself). It can + only send to one address at a time, so it spends a lot of + time copying duplicates of messages. Avoid this if at all + possible. + + uucp-new (obsolete name: "suucp") + The same as above, except that it assumes that in one rmail + command you can specify several recipients. It still has a + lot of other problems. + + uucp-dom + This UUCP mailer keeps everything as domain addresses. + Basically, it uses the SMTP mailer rewriting rules. This mailer + is only included if MAILER(smtp) is also specified. + + Unfortunately, a lot of UUCP mailer transport agents require + bangified addresses in the envelope, although you can use + domain-based addresses in the message header. (The envelope + shows up as the From_ line on UNIX mail.) So.... + + uucp-uudom + This is a cross between uucp-new (for the envelope addresses) + and uucp-dom (for the header addresses). It bangifies the + envelope sender (From_ line in messages) without adding the + local hostname, unless there is no host name on the address + at all (e.g., "wolf") or the host component is a UUCP host name + instead of a domain name ("somehost!wolf" instead of + "some.dom.ain!wolf"). This is also included only if MAILER(smtp) + is also specified. + +Examples: + +We are on host grasp.insa-lyon.fr (UUCP host name "grasp"). The +following summarizes the sender rewriting for various mailers. + +Mailer sender rewriting in the envelope +------ ------ ------------------------- +uucp-{old,new} wolf grasp!wolf +uucp-dom wolf wolf@grasp.insa-lyon.fr +uucp-uudom wolf grasp.insa-lyon.fr!wolf + +uucp-{old,new} wolf@fr.net grasp!fr.net!wolf +uucp-dom wolf@fr.net wolf@fr.net +uucp-uudom wolf@fr.net fr.net!wolf + +uucp-{old,new} somehost!wolf grasp!somehost!wolf +uucp-dom somehost!wolf somehost!wolf@grasp.insa-lyon.fr +uucp-uudom somehost!wolf grasp.insa-lyon.fr!somehost!wolf + +If you are using one of the domainized UUCP mailers, you really want +to convert all UUCP addresses to domain format -- otherwise, it will +do it for you (and probably not the way you expected). For example, +if you have the address foo!bar!baz (and you are not sending to foo), +the heuristics will add the @uucp.relay.name or @local.host.name to +this address. However, if you map foo to foo.host.name first, it +will not add the local hostname. You can do this using the uucpdomain +feature. + + ++-------------------+ +| TWEAKING RULESETS | ++-------------------+ + +For more complex configurations, you can define special rules. +The macro LOCAL_RULE_3 introduces rules that are used in canonicalizing +the names. Any modifications made here are reflected in the header. + +A common use is to convert old UUCP addresses to SMTP addresses using +the UUCPSMTP macro. For example: + + LOCAL_RULE_3 + UUCPSMTP(decvax, decvax.dec.com) + UUCPSMTP(research, research.att.com) + +will cause addresses of the form "decvax!user" and "research!user" +to be converted to "user@decvax.dec.com" and "user@research.att.com" +respectively. + +This could also be used to look up hosts in a database map: + + LOCAL_RULE_3 + R$* < @ $+ > $* $: $1 < @ $(hostmap $2 $) > $3 + +This map would be defined in the LOCAL_CONFIG portion, as shown below. + +Similarly, LOCAL_RULE_0 can be used to introduce new parsing rules. +For example, new rules are needed to parse hostnames that you accept +via MX records. For example, you might have: + + LOCAL_RULE_0 + R$+ <@ host.dom.ain.> $#uucp $@ cnmat $: $1 < @ host.dom.ain.> + +You would use this if you had installed an MX record for cnmat.Berkeley.EDU +pointing at this host; this rule catches the message and forwards it on +using UUCP. + +You can also tweak rulesets 1 and 2 using LOCAL_RULE_1 and LOCAL_RULE_2. +These rulesets are normally empty. + +A similar macro is LOCAL_CONFIG. This introduces lines added after the +boilerplate option setting but before rulesets, and can be used to +declare local database maps or whatever. For example: + + LOCAL_CONFIG + Khostmap hash /etc/hostmap.db + Kyplocal nis -m hosts.byname + + ++---------------------------+ +| MASQUERADING AND RELAYING | ++---------------------------+ + +You can have your host masquerade as another using + + MASQUERADE_AS(host.domain) + +This causes mail being sent to be labeled as coming from the +indicated host.domain, rather than $j. One normally masquerades as +one of one's own subdomains (for example, it's unlikely that I would +choose to masquerade as an MIT site). This behaviour is modified by +a plethora of FEATUREs; in particular, see masquerade_envelope, +allmasquerade, limited_masquerade, and masquerade_entire_domain. + +The masquerade name is not normally canonified, so it is important +that it be your One True Name, that is, fully qualified and not a +CNAME. However, if you use a CNAME, the receiving side may canonify +it for you, so don't think you can cheat CNAME mapping this way. + +Normally the only addresses that are masqueraded are those that come +from this host (that is, are either unqualified or in $=w, the list +of local domain names). You can augment this list using + + MASQUERADE_DOMAIN(otherhost.domain) + +The effect of this is that although mail to user@otherhost.domain +will not be delivered locally, any mail including any user@otherhost.domain +will, when relayed, be rewritten to have the MASQUERADE_AS address. +This can be a space-separated list of names. + +If these names are in a file, you can use + + MASQUERADE_DOMAIN_FILE(filename) + +to read the list of names from the indicated file. + +Normally only header addresses are masqueraded. If you want to +masquerade the envelope as well, use + + FEATURE(masquerade_envelope) + +There are always users that need to be "exposed" -- that is, their +internal site name should be displayed instead of the masquerade name. +Root is an example. You can add users to this list using + + EXPOSED_USER(usernames) + +This adds users to class E; you could also use something like + + FE/etc/sendmail.cE + +You can also arrange to relay all unqualified names (that is, names +without @host) to a relay host. For example, if you have a central +email server, you might relay to that host so that users don't have +to have .forward files or aliases. You can do this using + + define(`LOCAL_RELAY', mailer:hostname) + +The ``mailer:'' can be omitted, in which case the mailer defaults to +"relay". There are some user names that you don't want relayed, perhaps +because of local aliases. A common example is root, which may be +locally aliased. You can add entries to this list using + + LOCAL_USER(usernames) + +This adds users to class L; you could also use something like + + FL/etc/sendmail.cL + +If you want all incoming mail sent to a centralized hub, as for a +shared /var/spool/mail scheme, use + + define(`MAIL_HUB', mailer:hostname) + +Again, ``mailer:'' defaults to "relay". If you define both LOCAL_RELAY +and MAIL_HUB _AND_ you have FEATURE(stickyhost), unqualified names will +be sent to the LOCAL_RELAY and other local names will be sent to MAIL_HUB. +Names in $=L will be delivered locally, so you MUST have aliases or +.forward files for them. + +For example, if you are on machine mastodon.CS.Berkeley.EDU and you have +FEATURE(stickyhost), the following combinations of settings will have the +indicated effects: + +email sent to.... eric eric@mastodon.CS.Berkeley.EDU + +LOCAL_RELAY set to mail.CS.Berkeley.EDU (delivered locally) +mail.CS.Berkeley.EDU (no local aliasing) (aliasing done) + +MAIL_HUB set to mammoth.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU +mammoth.CS.Berkeley.EDU (aliasing done) (aliasing done) + +Both LOCAL_RELAY and mail.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU +MAIL_HUB set as above (no local aliasing) (aliasing done) + +If you do not have FEATURE(stickyhost) set, then LOCAL_RELAY and +MAIL_HUB act identically, with MAIL_HUB taking precedence. + +If you want all outgoing mail to go to a central relay site, define +SMART_HOST as well. Briefly: + + LOCAL_RELAY applies to unqualified names (e.g., "eric"). + MAIL_HUB applies to names qualified with the name of the + local host (e.g., "eric@mastodon.CS.Berkeley.EDU"). + SMART_HOST applies to names qualified with other hosts. + +However, beware that other relays (e.g., UUCP_RELAY, BITNET_RELAY, +DECNET_RELAY, and FAX_RELAY) take precedence over SMART_HOST, so if you +really want absolutely everything to go to a single central site you will +need to unset all the other relays -- or better yet, find or build a +minimal config file that does this. + +For duplicate suppression to work properly, the host name is best +specified with a terminal dot: + + define(`MAIL_HUB', `host.domain.') + note the trailing dot ---^ + + ++---------------------------------+ +| ANTI-SPAM CONFIGURATION CONTROL | ++---------------------------------+ + +The primary anti-spam features available in sendmail are: + +* Relaying is denied by default. +* Better checking on sender information. +* Access database. +* Header checks. + +Relaying (transmission of messages from a site outside your domain to +another site outside your domain) is denied by default. Note that +this changed in sendmail 8.9; previous versions allowed relaying by +default. If you want to revert to the old behaviour, you will need +to use FEATURE(promiscuous_relay). You can allow certain domains to +relay through your server by adding their domain name or IP address to +class 'R' ($=R) using RELAY_DOMAIN() and RELAY_DOMAIN_FILE() or via the +access database (described below). + +If you use + + FEATURE(relay_entire_domain) + +then any host in any of your local domains (that is, the $=m class) +will be relayed. + +You can also allow relaying based on the MX records of the host +portion of an incoming recipient address by using + + FEATURE(relay_based_on_MX) + +For example, if your server receives a recipient of user@domain.com +and domain.com lists your server in its MX records, the mail will be +accepted. Note that this will stop spammers from using your host to +relay spam but it will not stop outsiders from using your server as a +relay for their site. Along the same lines, + + FEATURE(relay_local_from) + +will allow relaying if the sender specifies a return path (i.e. +MAIL FROM: ) domain which is a local domain. This a +dangerous feature as it will allow spammers to spam using your mail +server by simply specifying a return address of user@your.domain.com. +It should not be used unless absolutely necessary. + +If source routing is used in the recipient address (i.e. +RCPT TO: ), sendmail will check +user@site.com for relaying if othersite.com is an allowed relay host +in either class 'R', class 'm' if FEATURE(relay_entire_domain) is used, +or the access database if FEATURE(access_db) is used. To prevent +the address from being stripped down, use: + + FEATURE(loose_relay_check) + +If you think you need to use this feature, you probably do not. This +should only be used for sites which have no control over the addresses +that they provide a gateway for. Use this FEATURE with caution as it +can allow spammers to relay through your server if not setup properly. + +As of 8.9, sendmail will refuse mail if the MAIL FROM: parameter has +an unresolvable domain (i.e., one that DNS, your local name service, +or special case rules in ruleset 3 cannot locate). If you want to +continue to accept such domains, e.g. because you are inside a +firewall that has only a limited view of the Internet host name space +(note that you will not be able to return mail to them unless you have +some "smart host" forwarder), use + + FEATURE(accept_unresolvable_domains) + +sendmail will also refuse mail if the MAIL FROM: parameter is not +fully qualified (i.e., contains a domain as well as a user). If you +want to continue to accept such senders, use + + FEATURE(accept_unqualified_senders) + +An ``access'' database can be created to accept or reject mail from +selected domains. For example, you may choose to reject all mail +originating from known spammers. To enable such a database, use + + FEATURE(access_db) + +The FEATURE macro can accept a second parameter giving the key file +definition for the database; for example + + FEATURE(access_db, hash -o /etc/mail/access) + +The table itself uses e-mail addresses, domain names, and network +numbers as keys. For example, + + spammer@aol.com REJECT + cyberspammer.com REJECT + 206.117.147 REJECT + +would refuse mail from spammer@aol.com, any user from cyberspammer.com +(or any host within the cyberspammer.com domain), and any host on the +206.117.147.* network. + +The value part of the map can contain: + + OK accept mail even if other rules in the + running ruleset would reject it. + RELAY Allow domain to relay through your SMTP + server. RELAY also serves an implicit + OK for the other checks. + REJECT reject the sender/recipient with a general + purpose message. + DISCARD discard the message completely using + the $#discard mailer + ### any text where ### is an RFC 821 compliant error code + and "any text" is a message to return for + the command. + +For example: + + cyberspammer.com 550 We don't accept mail from spammers + okay.cyberspammer.com OK + sendmail.org OK + 128.32 RELAY + +would accept mail from okay.cyberspammer.com, but would reject mail +from all other hosts at cyberspammer.com with the indicated message. +It would allow accept mail from any hosts in the sendmail.org domain, +and allow relaying for the 128.32.*.* network. Note, UUCP users may +need to add hostname.UUCP to the access database or class 'R' ($=R). +If you also use: + + FEATURE(relay_hosts_only) + +then the above example will allow relaying for sendmail.org, but not +hosts within the sendmail.org domain. Note that this will also require +hosts listed in class 'R' ($=R) to be fully qualified host names. + +You can also use the access database to block sender addresses based on +the username portion of the address. For example: + + FREE.STEALTH.MAILER@ 550 Spam not accepted + +Note that you must include the @ after the username to signify that +this database entry is for checking only the username portion of the +sender address. + +If you use: + + FEATURE(blacklist_recipients) + +then you can add entries to the map for local users, hosts in your +domains, or addresses in your domain which should not receive mail: + + badlocaluser 550 Mailbox disabled for this username + host.mydomain.com 550 That host does not accept mail + user@otherhost.mydomain.com 550 Mailbox disabled for this recipient + +This would prevent a recipient of badlocaluser@mydomain.com, any +user at host.mydomain.com, and the single address +user@otherhost.mydomain.com from receiving mail. + +There is also a ``Realtime Blackhole List'' run by the MAPS project +at http://maps.vix.com/. This is a database maintained in DNS of +spammers. To use this database, use + + FEATURE(rbl) + +This will cause sendmail to reject mail from any site in the +Realtime Blackhole List database. You can specify an alternative +RBL name server to contact by specifying an argument to the FEATURE. + +The features described above make use of the check_relay, check_mail, +and check_rcpt rulesets. If you wish to include your own checks, +you can put your checks in the rulesets Local_check_relay, +Local_check_mail, and Local_check_rcpt. For example if you wanted to +block senders with all numeric usernames (i.e. 2312343@bigisp.com), +you would use Local_check_mail and the new regex map: + + LOCAL_CONFIG + Kallnumbers regex -a@MATCH ^[0-9]+$ + + LOCAL_RULESETS + SLocal_check_mail + # check address against various regex checks + R$* $: $>Parse0 $>3 $1 + R$+ < @ bigisp.com. > $* $: $(allnumbers $1 $) + R@MATCH $#error $: 553 Header Error + +These rules are called with the original arguments of the corresponding +check_* ruleset. If the local ruleset returns $#OK, no further checking +is done by the features described above and the mail is accepted. If the +local ruleset resolves to a mailer (such as $#error or $#discard), the +appropriate action is taken. Otherwise, the results of the local +rewriting are ignored. + + +You can also reject mail on the basis of the contents of headers. +This is done by adding a ruleset call to the 'H' header definition command +in sendmail.cf. For example, this can be used to check the validity of +a Message-ID: header: + + LOCAL_RULESETS + HMessage-Id: $>CheckMessageId + + SCheckMessageId + R< $+ @ $+ > $@ OK + R$* $#error $: 553 Header Error + + ++--------------------------------+ +| ADDING NEW MAILERS OR RULESETS | ++--------------------------------+ + +Sometimes you may need to add entirely new mailers or rulesets. They +should be introduced with the constructs MAILER_DEFINITIONS and +LOCAL_RULESETS respectively. For example: + + MAILER_DEFINITIONS + Mmymailer, ... + ... + + LOCAL_RULESETS + Smyruleset + ... + + ++-------------------------------+ +| NON-SMTP BASED CONFIGURATIONS | ++-------------------------------+ + +These configuration files are designed primarily for use by SMTP-based +sites. I don't pretend that they are well tuned for UUCP-only or +UUCP-primarily nodes (the latter is defined as a small local net +connected to the rest of the world via UUCP). However, there is one +hook to handle some special cases. + +You can define a ``smart host'' that understands a richer address syntax +using: + + define(`SMART_HOST', mailer:hostname) + +In this case, the ``mailer:'' defaults to "relay". Any messages that +can't be handled using the usual UUCP rules are passed to this host. + +If you are on a local SMTP-based net that connects to the outside +world via UUCP, you can use LOCAL_NET_CONFIG to add appropriate rules. +For example: + + define(`SMART_HOST', suucp:uunet) + LOCAL_NET_CONFIG + R$* < @ $* .$m. > $* $#smtp $@ $2.$m. $: $1 < @ $2.$m. > $3 + +This will cause all names that end in your domain name ($m) via +SMTP; anything else will be sent via suucp (smart UUCP) to uunet. +If you have FEATURE(nocanonify), you may need to omit the dots after +the $m. If you are running a local DNS inside your domain which is +not otherwise connected to the outside world, you probably want to +use: + + define(`SMART_HOST', smtp:fire.wall.com) + LOCAL_NET_CONFIG + R$* < @ $* . > $* $#smtp $@ $2. $: $1 < @ $2. > $3 + +That is, send directly only to things you found in your DNS lookup; +anything else goes through SMART_HOST. + +You may need to turn off the anti-spam rules in order to accept +UUCP mail with FEATURE(promiscuous_relay) and +FEATURE(accept_unresolvable_domains). + + ++-----------+ +| WHO AM I? | ++-----------+ + +Normally, the $j macro is automatically defined to be your fully +qualified domain name (FQDN). Sendmail does this by getting your +host name using gethostname and then calling gethostbyname on the +result. For example, in some environments gethostname returns +only the root of the host name (such as "foo"); gethostbyname is +supposed to return the FQDN ("foo.bar.com"). In some (fairly rare) +cases, gethostbyname may fail to return the FQDN. In this case +you MUST define confDOMAIN_NAME to be your fully qualified domain +name. This is usually done using: + + Dmbar.com + define(`confDOMAIN_NAME', `$w.$m')dnl + + ++--------------------+ +| USING MAILERTABLES | ++--------------------+ + +To use FEATURE(mailertable), you will have to create an external +database containing the routing information for various domains. +For example, a mailertable file in text format might be: + + .my.domain xnet:%1.my.domain + uuhost1.my.domain suucp:uuhost1 + .bitnet smtp:relay.bit.net + +This should normally be stored in /etc/mailertable. The actual +database version of the mailertable is built using: + + makemap hash /etc/mailertable.db < /etc/mailertable + +The semantics are simple. Any LHS entry that does not begin with +a dot matches the full host name indicated. LHS entries beginning +with a dot match anything ending with that domain name -- that is, +they can be thought of as having a leading "*" wildcard. Matching +is done in order of most-to-least qualified -- for example, even +though ".my.domain" is listed first in the above example, an entry +of "uuhost1.my.domain" will match the second entry since it is +more explicit. + +The RHS should always be a "mailer:host" pair. The mailer is the +configuration name of a mailer (that is, an `M' line in the +sendmail.cf file). The "host" will be the hostname passed to +that mailer. In domain-based matches (that is, those with leading +dots) the "%1" may be used to interpolate the wildcarded part of +the host name. For example, the first line above sends everything +addressed to "anything.my.domain" to that same host name, but using +the (presumably experimental) xnet mailer. + +In some cases you may want to temporarily turn off MX records, +particularly on gateways. For example, you may want to MX +everything in a domain to one machine that then forwards it +directly. To do this, you might use the DNS configuration: + + *.domain. IN MX 0 relay.machine + +and on relay.machine use the mailertable: + + .domain smtp:[gateway.domain] + +The [square brackets] turn off MX records for this host only. +If you didn't do this, the mailertable would use the MX record +again, which would give you an MX loop. + + ++--------------------------------+ +| USING USERDB TO MAP FULL NAMES | ++--------------------------------+ + +The user database was not originally intended for mapping full names +to login names (e.g., Eric.Allman => eric), but some people are using +it that way. (I would recommend that you set up aliases for this +purpose instead -- since you can specify multiple alias files, this +is fairly easy.) The intent was to locate the default maildrop at +a site, but allow you to override this by sending to a specific host. + +If you decide to set up the user database in this fashion, it is +imperative that you not use FEATURE(stickyhost) -- otherwise, +e-mail sent to Full.Name@local.host.name will be rejected. + +To build the internal form of the user database, use: + + makemap btree /usr/data/base.db < /usr/data/base.txt + +As a general rule, I am adamantly opposed to using full names as +e-mail addresses, since they are not in any sense unique. For example, +the Unix software-development community has two Andy Tannenbaums, +at least two well-known Peter Deutsches, and at one time Bell Labs +had two Stephen R. Bournes with offices along the same hallway. +Which one will be forced to suffer the indignity of being +Stephen_R_Bourne_2? The less famous of the two, or the one that +was hired later? + +Finger should handle full names (and be fuzzy). Mail should use +handles, and not be fuzzy. [Not that I expect anyone to pay any +attention to my opinions.] + + ++--------------------------------+ +| MISCELLANEOUS SPECIAL FEATURES | ++--------------------------------+ + +Plussed users + Sometimes it is convenient to merge configuration on a + centralized mail machine, for example, to forward all + root mail to a mail server. In this case it might be + useful to be able to treat the root addresses as a class + of addresses with subtle differences. You can do this + using plussed users. For example, a client might include + the alias: + + root: root+client1@server + + On the server, this will match an alias for "root+client1". + If that is not found, the alias "root+*" will be tried, + then "root". + +LDAP + For notes on use LDAP in sendmail, see + http://www.stanford.edu/~bbense/Inst.html + + + ++----------------+ +| SECURITY NOTES | ++----------------+ + +A lot of sendmail security comes down to you. Sendmail 8 is much +more careful about checking for security problems than previous +versions, but there are some things that you still need to watch +for. In particular: + +* Make sure the aliases file isn't writable except by trusted + system personnel. This includes both the text and database + version. + +* Make sure that other files that sendmail reads, such as the + mailertable, are only writable by trusted system personnel. + +* The queue directory should not be world writable PARTICULARLY + if your system allows "file giveaways" (that is, if a non-root + user can chown any file they own to any other user). + +* If your system allows file giveaways, DO NOT create a publically + writable directory for forward files. This will allow anyone + to steal anyone else's e-mail. Instead, create a script that + copies the .forward file from users' home directories once a + night (if you want the non-NFS-mounted forward directory). + +* If your system allows file giveaways, you'll find that + sendmail is much less trusting of :include: files -- in + particular, you'll have to have /SENDMAIL/ANY/SHELL/ in + /etc/shells before they will be trusted (that is, before + files and programs listed in them will be honored). + +In general, file giveaways are a mistake -- if you can turn them +off I recommend you do so. + + ++--------------------------------+ +| TWEAKING CONFIGURATION OPTIONS | ++--------------------------------+ + +There are a large number of configuration options that don't normally +need to be changed. However, if you feel you need to tweak them, you +can define the following M4 variables. This list is shown in four +columns: the name you define, the default value for that definition, +the option or macro that is affected (either Ox for an option or Dx +for a macro), and a brief description. Greater detail of the semantics +can be found in the Installation and Operations Guide. + +Some options are likely to be deprecated in future versions -- that is, +the option is only included to provide back-compatibility. These are +marked with "*". + +Remember that these options are M4 variables, and hence may need to +be quoted. In particular, arguments with commas will usually have to +be ``double quoted, like this phrase'' to avoid having the comma +confuse things. This is common for alias file definitions and for +the read timeout. + +M4 Variable Name Configuration Description & [Default] +================ ============= ======================= +confMAILER_NAME $n macro [MAILER-DAEMON] The sender name used + for internally generated outgoing + messages. +confDOMAIN_NAME $j macro If defined, sets $j.

Use confMAX_MESSAGE_SIZE + for the second value now.) +confMAX_MESSAGE_SIZE MaxMessageSize [infinite] The maximum size of messages + that will be accepted (in bytes). +confBLANK_SUB BlankSub [.] Blank (space) substitution + character. +confCON_EXPENSIVE HoldExpensive [False] Avoid connecting immediately + to mailers marked expensive? +confCHECKPOINT_INTERVAL CheckpointInterval + [10] Checkpoint queue files every N + recipients. +confDELIVERY_MODE DeliveryMode [background] Default delivery mode. +confAUTO_REBUILD AutoRebuildAliases + [False] Automatically rebuild alias + file if needed. +confERROR_MODE ErrorMode [print] Error message mode. +confERROR_MESSAGE ErrorHeader [undefined] Error message header/file. +confSAVE_FROM_LINES SafeFromLine Save extra leading From_ lines. +confTEMP_FILE_MODE TempFileMode [0600] Temporary file mode. +confMATCH_GECOS MatchGECOS [False] Match GECOS field. +confMAX_HOP MaxHopCount [25] Maximum hop count. +confIGNORE_DOTS* IgnoreDots [False; always False in -bs or -bd mode] + Ignore dot as terminator for incoming + messages? +confBIND_OPTS ResolverOptions [undefined] Default options for DNS + resolver. +confMIME_FORMAT_ERRORS* SendMimeErrors [True] Send error messages as MIME- + encapsulated messages per RFC 1344. +confFORWARD_PATH ForwardPath [$z/.forward.$w:$z/.forward] + The colon-separated list of places to + search for .forward files. N.B.: see + the Security Notes section. +confMCI_CACHE_SIZE ConnectionCacheSize + [2] Size of open connection cache. +confMCI_CACHE_TIMEOUT ConnectionCacheTimeout + [5m] Open connection cache timeout. +confHOST_STATUS_DIRECTORY HostStatusDirectory + [undefined] If set, host status is kept + on disk between sendmail runs in the + named directory tree. This need not be + a full pathname, in which case it is + interpreted relative to the queue + directory. +confSINGLE_THREAD_DELIVERY SingleThreadDelivery + [False] If this option and the + HostStatusDirectory option are both + set, single thread deliveries to other + hosts. That is, don't allow any two + sendmails on this host to connect + simultaneously to any other single + host. This can slow down delivery in + some cases, in particular since a + cached but otherwise idle connection + to a host will prevent other sendmails + from connecting to the other host. +confUSE_ERRORS_TO* UserErrorsTo [False] Use the Errors-To: header to + deliver error messages. This should + not be necessary because of general + acceptance of the envelope/header + distinction. +confLOG_LEVEL LogLevel [9] Log level. +confME_TOO MeToo [False] Include sender in group + expansions. +confCHECK_ALIASES CheckAliases [False] Check RHS of aliases when + running newaliases. Since this does + DNS lookups on every address, it can + slow down the alias rebuild process + considerably on large alias files. +confOLD_STYLE_HEADERS* OldStyleHeaders [True] Assume that headers without + special chars are old style. +confDAEMON_OPTIONS DaemonPortOptions + [none] SMTP daemon options. +confPRIVACY_FLAGS PrivacyOptions [authwarnings] Privacy flags. +confCOPY_ERRORS_TO PostmasterCopy [undefined] Address for additional + copies of all error messages. +confQUEUE_FACTOR QueueFactor [600000] Slope of queue-only function. +confDONT_PRUNE_ROUTES DontPruneRoutes [False] Don't prune down route-addr + syntax addresses to the minimum + possible. +confSAFE_QUEUE* SuperSafe [True] Commit all messages to disk + before forking. +confTO_INITIAL Timeout.initial [5m] The timeout waiting for a response + on the initial connect. +confTO_CONNECT Timeout.connect [0] The timeout waiting for an initial + connect() to complete. This can only + shorten connection timeouts; the kernel + silently enforces an absolute maximum + (which varies depending on the system). +confTO_ICONNECT Timeout.iconnect + [undefined] Like Timeout.connect, but + applies only to the very first attempt + to connect to a host in a message. + This allows a single very fast pass + followed by more careful delivery + attempts in the future. +confTO_HELO Timeout.helo [5m] The timeout waiting for a response + to a HELO or EHLO command. +confTO_MAIL Timeout.mail [10m] The timeout waiting for a + response to the MAIL command. +confTO_RCPT Timeout.rcpt [1h] The timeout waiting for a response + to the RCPT command. +confTO_DATAINIT Timeout.datainit + [5m] The timeout waiting for a 354 + response from the DATA command. +confTO_DATABLOCK Timeout.datablock + [1h] The timeout waiting for a block + during DATA phase. +confTO_DATAFINAL Timeout.datafinal + [1h] The timeout waiting for a response + to the final "." that terminates a + message. +confTO_RSET Timeout.rset [5m] The timeout waiting for a response + to the RSET command. +confTO_QUIT Timeout.quit [2m] The timeout waiting for a response + to the QUIT command. +confTO_MISC Timeout.misc [2m] The timeout waiting for a response + to other SMTP commands. +confTO_COMMAND Timeout.command [1h] In server SMTP, the timeout waiting + for a command to be issued. +confTO_IDENT Timeout.ident [30s] The timeout waiting for a response + to an IDENT query. +confTO_FILEOPEN Timeout.fileopen + [60s] The timeout waiting for a file + (e.g., :include: file) to be opened. +confTO_QUEUERETURN Timeout.queuereturn + [5d] The timeout before a message is + returned as undeliverable. +confTO_QUEUERETURN_NORMAL + Timeout.queuereturn.normal + [undefined] As above, for normal + priority messages. +confTO_QUEUERETURN_URGENT + Timeout.queuereturn.urgent + [undefined] As above, for urgent + priority messages. +confTO_QUEUERETURN_NONURGENT + Timeout.queuereturn.non-urgent + [undefined] As above, for non-urgent + (low) priority messages. +confTO_QUEUEWARN Timeout.queuewarn + [4h] The timeout before a warning + message is sent to the sender telling + them that the message has been deferred. +confTO_QUEUEWARN_NORMAL Timeout.queuewarn.normal + [undefined] As above, for normal + priority messages. +confTO_QUEUEWARN_URGENT Timeout.queuewarn.urgent + [undefined] As above, for urgent + priority messages. +confTO_QUEUEWARN_NONURGENT + Timeout.queuewarn.non-urgent + [undefined] As above, for non-urgent + (low) priority messages. +confTO_HOSTSTATUS Timeout.hoststatus + [30m] How long information about host + statuses will be maintained before it + is considered stale and the host should + be retried. This applies both within + a single queue run and to persistent + information (see below). +confTIME_ZONE TimeZoneSpec [USE_SYSTEM] Time zone info -- can be + USE_SYSTEM to use the system's idea, + USE_TZ to use the user's TZ envariable, + or something else to force that value. +confDEF_USER_ID DefaultUser [1:1] Default user id. +confUSERDB_SPEC UserDatabaseSpec + [undefined] User database specification. +confFALLBACK_MX FallbackMXhost [undefined] Fallback MX host. +confTRY_NULL_MX_LIST TryNullMXList [False] If we are the best MX for a + host and haven't made other + arrangements, try connecting to the + host directly; normally this would be + a config error. +confQUEUE_LA QueueLA [8] Load average at which queue-only + function kicks in. +confREFUSE_LA RefuseLA [12] Load average at which incoming + SMTP connections are refused. +confMAX_DAEMON_CHILDREN MaxDaemonChildren + [undefined] The maximum number of + children the daemon will permit. After + this number, connections will be + rejected. If not set or <= 0, there is + no limit. +confCONNECTION_RATE_THROTTLE ConnectionRateThrottle + [undefined] The maximum number of + connections permitted per second. + After this many connections are + accepted, further connections will be + delayed. If not set or <= 0, there is + no limit. +confWORK_RECIPIENT_FACTOR + RecipientFactor [30000] Cost of each recipient. +confSEPARATE_PROC ForkEachJob [False] Run all deliveries in a separate + process. +confWORK_CLASS_FACTOR ClassFactor [1800] Priority multiplier for class. +confWORK_TIME_FACTOR RetryFactor [90000] Cost of each delivery attempt. +confQUEUE_SORT_ORDER QueueSortOrder [Priority] Queue sort algorithm: + Priority, Host, or Time. +confMIN_QUEUE_AGE MinQueueAge [0] The minimum amount of time a job + must sit in the queue between queue + runs. This allows you to set the + queue run interval low for better + responsiveness without trying all + jobs in each run. +confDEF_CHAR_SET DefaultCharSet [unknown-8bit] When converting + unlabeled 8 bit input to MIME, the + character set to use by default. +confSERVICE_SWITCH_FILE ServiceSwitchFile + [/etc/service.switch] The file to use + for the service switch on systems that + do not have a system-defined switch. +confHOSTS_FILE HostsFile [/etc/hosts] The file to use when doing + "file" type access of hosts names. +confDIAL_DELAY DialDelay [0s] If a connection fails, wait this + long and try again. Zero means "don't + retry". This is to allow "dial on + demand" connections to have enough time + to complete a connection. +confNO_RCPT_ACTION NoRecipientAction + [none] What to do if there are no legal + recipient fields (To:, Cc: or Bcc:) + in the message. Legal values can + be "none" to just leave the + nonconforming message as is, "add-to" + to add a To: header with all the + known recipients (which may expose + blind recipients), "add-apparently-to" + to do the same but use Apparently-To: + instead of To:, "add-bcc" to add an + empty Bcc: header, or + "add-to-undisclosed" to add the header + ``To: undisclosed-recipients:;''. +confSAFE_FILE_ENV SafeFileEnvironment + [undefined] If set, sendmail will do a + chroot() into this directory before + writing files. +confCOLON_OK_IN_ADDR ColonOkInAddr [True unless Configuration Level > 6] + If set, colons are treated as a regular + character in addresses. If not set, + they are treated as the introducer to + the RFC 822 "group" syntax. Colons are + handled properly in route-addrs. This + option defaults on for V5 and lower + configuration files. +confMAX_QUEUE_RUN_SIZE MaxQueueRunSize [0] If set, limit the maximum size of + any given queue run to this number of + entries. Essentially, this will stop + reading the queue directory after this + number of entries are reached; it does + _not_ pick the highest priority jobs, + so this should be as large as your + system can tolerate. If not set, there + is no limit. +confDONT_EXPAND_CNAMES DontExpandCnames + [False] If set, $[ ... $] lookups that + do DNS based lookups do not expand + CNAME records. This currently violates + the published standards, but the IETF + seems to be moving toward legalizing + this. For example, if "FTP.Foo.ORG" + is a CNAME for "Cruft.Foo.ORG", then + with this option set a lookup of + "FTP" will return "FTP.Foo.ORG"; if + clear it returns "Cruft.FOO.ORG". N.B. + you may not see any effect until your + downstream neighbors stop doing CNAME + lookups as well. +confFROM_LINE UnixFromLine [From $g $d] The From_ line used + when sending to files or programs. +confSINGLE_LINE_FROM_HEADER SingleLineFromHeader + [False] From: lines that have + embedded newlines are unwrapped + onto one line. +confALLOW_BOGUS_HELO AllowBogusHELO [False] Allow HELO SMTP command that + does not include a host name. +confMUST_QUOTE_CHARS MustQuoteChars [.'] Characters to be quoted in a full + name phrase (@,;:\()[] are automatic). +confOPERATORS OperatorChars [.:%@!^/[]+] Address operator + characters. +confSMTP_LOGIN_MSG SmtpGreetingMessage + [$j Sendmail $v/$Z; $b] + The initial (spontaneous) SMTP + greeting message. The word "ESMTP" + will be inserted between the first and + second words to convince other + sendmails to try to speak ESMTP. +confDONT_INIT_GROUPS DontInitGroups [False] If set, the initgroups(3) + routine will never be invoked. You + might want to do this if you are + running NIS and you have a large group + map, since this call does a sequential + scan of the map; in a large site this + can cause your ypserv to run + essentially full time. If you set + this, agents run on behalf of users + will only have their primary + (/etc/passwd) group permissions. +confUNSAFE_GROUP_WRITES UnsafeGroupWrites + [False] If set, group-writable + :include: and .forward files are + considered "unsafe", that is, programs + and files cannot be directly referenced + from such files. World-writable files + are always considered unsafe. +confDOUBLE_BOUNCE_ADDRESS DoubleBounceAddress + [postmaster] If an error occurs when + sending an error message, send that + "double bounce" error message to this + address. +confRUN_AS_USER RunAsUser [undefined] If set, become this user + when reading and delivering mail. + Causes all file reads (e.g., .forward + and :include: files) to be done as + this user. Also, all programs will + be run as this user, and all output + files will be written as this user. + Intended for use only on firewalls + where users do not have accounts. +confMAX_RCPTS_PER_MESSAGE MaxRecipientsPerMessage + [infinite] If set, allow no more than + the specified number of recipients in + an SMTP envelope. Further recipients + receive a 452 error code (i.e., they + are deferred for the next delivery + attempt). +confDONT_PROBE_INTERFACES DontProbeInterfaces + [False] If set, sendmail will _not_ + insert the names and addresses of any + local interfaces into the $=w class + (list of known "equivalent" addresses). + If you set this, you must also include + some support for these addresses (e.g., + in a mailertable entry) -- otherwise, + mail to addresses in this list will + bounce with a configuration error. +confDONT_BLAME_SENDMAIL DontBlameSendmail + [safe] Override sendmail's file + safety checks.

In the longer term, +it is recommended that one move to using an m4 based configuration such +as those shipped with sendmail, but if you're like me and have made +enough modifications to your .cf file that you'd rather put that task +off until later, here's the sum total of my experience to get you to +version 8 with minimal pain. I'll cover .cf as well as build issues. + +Some background - as many are surely aware, Sun has some "special" +features in the sendmail they ship ($%x, %y LHS lookup, NIS alias DB +search, etc.). (Some of those features can be had in alternative forms +in IDA sendmail, but v8 has picked up some IDA capabilities as well as +new ones, making it IMHO a most desirable version to go to.) What I +will explain below includes v8 functional "equivalences" to these Sun +sendmail features. + +So with that out of the way, let's begin. + +First, some assumptions: + + 1) I'm going to assume you've got sendmail version 8.6 or + later in hand - if not, grab it from ftp.cs.berkeley.edu + in the ucb/sendmail directory. There are bugs in earlier + versions which affect some of the needed functionality. + + 2) Second, I'm going to detail this based upon the + "sendmail.main.cf" configuration. (BTW, if you attempt + to move to using an m4 generated config in the future, + MAIL_HUB is the feature which should provide similar + functionality). + + In general, the changes will be similar for a subsidiary + file, but since we (my TI group) funnel all non-local mail + through our mailhost, we're not as interested in getting v8 + to run on such systems and I haven't tried it. + + 3) You're using DNS and sendmail.mx. If you're not, you ought + to be, even if you're also running it along with NIS (which + we do - except for gethostbyxxx() lookups, which I'll be + talking about later). I would imagine you could get things + running OK without DNS support, but I haven't tried it myself. + + 4) You're not mounting /var/spool/mail from other systems. + I haven't found a v8 feature to guarantee this will work + correctly. Anyway, in the past, we've tried doing that + here and found it to be a rather "ugly" feature, though + Sun ostensibly supports it ("R" option). Perhaps v8 + will one day have a similar feature, but for now, bottom + line, I would recommend against it. + + 5) You're not on Solaris or using NIS+. I'm on 4.1.3. I've + looked at Solaris briefly and have noted that things are + pretty much similar there except that they've moved some + things into the /etc/mail directory. I'd guess the + executables aren't functionally all that different from + what they had before - the configs are roughly the same. + So I'd bet most of what I say in here will apply to + Solaris. + +OK, let's configure our sendmail.cf! I'll just go from the top down... + + VARIOUS DECLARATIONS + +1) For v8, you need to define your .cf as AT LEAST a version level 4 + configuration. Add the following line: + + V4 + + There are some issues regarding certain predefined macros - $w, $j, and + $m. With a V4 configuration: + + $w is defined to be the hostname, which will usually be fully + qualified (i.e. "firefly.add.itg.ti.com"). + + $j should have the same value as $w. + + $m will be predefined as the domain portion of $w + (ex. "add.itg.ti.com"). + + One note about this - if your configuration relies on the "w" macro to + be the "simple" hostname (as mine does)... + + If the configuration version is 5 or larger: + + $w is supposed to be the "simple" name (ex. "firefly") + + $j should be the fully qualified name (i.e. "firefly.add.itg.ti.com") + + $m will be predefined as the domain portion of $j + (ex. "add.itg.ti.com"). + + I have not experimented with the various combinations, so I cannot + guarantee you that the above definitions will always come out as + expected. Bottom line: if your sendmail.cf depends on $w being the + simple hostname, test it carefully or define the name explicitly, + for example: + + Dwfirefly + +2) To replace the Sun's "%y" feature, we must use a hostname mapping + feature in v8. If you want to do similar lookups with v8, you need + to define the following map (we'll go over the rules that use this + map later): + + Khostlookup host -f -m -a. + + This will define a "lookup only" map that is otherwise the same as + sendmail version 8's built-in "host" map (see the "Sendmail + Installation and Operation Guide" for details on this map.). + + An important note: Whether or not these lookups will be done via + NIS is a function of what gethostbyxxx() functions you link into + your sendmail. DO NOT redefine your host mapping to use NIS + explicitly within sendmail - there can be unexpected behaviour if + you do so (if you do any canonicalization in your .cf, you can get + incorrect results, for one thing). + + For example, DO NOT TRY: + + Khost nis -f -a. hosts.byname + +3) If you're doing reverse alias mapping as done in ruleset 22, instead of: + + DZmail.byaddr + + you'll need to declare the following: + + Kaliasrev nis -f -N mail.byaddr + +4) If you are doing any other NIS map lookups, you'll need to define the + map as done in the below example. I have a "mailhosts" map, which I + use to distinguish between local and non-local hosts. Look at the + sendmail doc for details on this stuff. + + Kmailhosts nis -f -m -a. mailhosts + +5) You might wish to add the following line to support Errors-To: headers. + I don't. + + Ol + +6) Comment out/remove the following line: + + OR + + The R option means something different under v8 - check the documentation + if you're interested in using it. + +7) If you're running NIS and have a separate alias map, BELOW the + following line where the alias file is declared: + + OA/etc/aliases + + ADD the following: + + OAnis:mail.aliases + + This will set things up so v8 will look at the local alias DB first, + then the NIS map, just as Sun sendmail does. + +8) Though you don't have to, I'd suggest changing: + + OT3d + + to use v8's warning feature, which allows a warning message to be + sent if a message cannot be delivered within a specified period. + I use: + + OT5d/4h + + which says - bounce after 5 days, warn after 4 hours. + +9) I set the following option to be explicit about how I want DNS + handled: + + OI +DNSRCH +DEFNAMES + +10) The following line: + + T root daemon uucp + + may be deleted, though it will be ignored if you leave it around. + +11) It would probably be good to change the version macro value (which + shows up in "Received:" headers) so no one debugging mail problems + gets the wrong idea about what config you're running under. Look + for something like: + + DVSMI-4.1 + + Mine, for example is: + + DVADD-HUB-2.1 + + RULESETS + +1) In ruleset 3, BELOW this rule: + + # basic textual canonicalization + R$*<$+>$* $2 basic RFC822 parsing + + +I add the following rule to remove a trailing dot in the domain spec so +it won't interfere with v8 mapping features, etc. (Having a trailing dot is +not RFC-compliant anyway.): + + R$+. $1 + +2) Because ruleset 5 is special in v8, I rename it to S95 and also change + all RHS expressions containing ">5" to use ">95" instead. In v8, + 5 is executed against addresses which resolve to the local mailer and + are not an alias. If you don't change S5 to something else, you might + get a surprise! + +3) If you're doing any lookups via the generalized NIS "$%x/$!x" + mechanisms (such as with the mailhost map I referred to earlier) it's + done differently under v8. For example: + + DMmailhosts + ... + R$*<@$%M.uucp>$* $#ether $@$2 $:$1<@$2>$3 + + takes a different map definition and two rules under version 8: + + Kmailhosts nis -f -m -a. mailhosts + ... + R$*<@$+.uucp>$* $: $1<@$(mailhosts $2 $).uucp>$3 + R$*<@$+..uucp>$* $#ether $@$2 $:$1<@$2>$3 + +4) Sun has a special case of the "$%x" feature for host lookups - "%y" is + automagically defined to do an NIS "hosts.byname" search with no other + definition, as done in the below example: + + R$*<@$%y.LOCAL>$* $#ether $@$2 $:$1<@$2>$3 + + (Sun does this in more than one place. But the above syntax is almost + identical in each - mostly a case of changing names to protect the + innocent.) + + In version 8, the predefined "host" map can be used to do essentially + the same thing. (However, whether or not it does an NIS lookup is + a function of what gethostbyxxx() functions are linked in.) + + Recall the map definition I mentioned earlier in the DECLARATIONS + section: + + Khostlookup host -f -m -a. + + Here's where we will use it. It will take two rules: + + R$*<@$+.LOCAL>$* $: $1<@$(hostlookup $2 $).LOCAL>$3 + R$*<@$+..LOCAL>$* $#ether $@$2 $:$1<@$2>$3 + + Note that this is almost verbatim the same change as was used in the + previous "mailhosts" example. + +5) Although Sun's default configs don't do this, because I mentioned + canonicalization earlier, it deserves an example, as it's illustrative + of the functional difference in the map definitions I discussed before. + This stuff is also convered in the "Sendmail Installation and Operation + Guide". + + Remember the built-in "host" map definition? As you'll recall, unlike + the "hostlookup" map we defined, "host" will actually CHANGE the + hostname in addition to appending a dot. "hostlookup" only appends a + dot if the name is found and doesn't change it otherwise. Anyway, + here's the example: + + R$*<@$+>$* $: $1<@$(host $2 $)>$3 canonicalize + R$*<@$+.>$* $1<@$2>$3 remove trailing dot + + Using the above, say you had input of: + + joe<@tilde> + + OR + + joe<@[128.247.160.56]> + + Assuming "tilde" or the IP address is found, it might be + canonicalized as: + + joe<@tilde.csc.ti.com> + +6) As another instance of the NIS lookup feature, with a slightly + different twist, Sun implements reverse alias mapping in ruleset 22 + with the below: + + DZmail.byaddr + ... + R$-<@$-> $:$>3${Z$1@$2$} invert aliases + + To use this feature under v8, change the above rule a (remember to + define the alias map as I showed earlier): + + R$-<@$-> $:$>3$(aliasrev $1@$2 $) invert aliases + + + MAILER DEFINITIONS + +1) Where "TCP" is defined in the "P=" and "A=" parameters of mailers, I + changed it to "IPC". Version 8 will accept "TCP", but "IPC" is + preferred. + +2) On all IPC mailers, I also defined "E=\r\n" and added an "L=1000" as + in the below example: + + Mether, P=[IPC], F=mDFMuCX, S=11, R=21, L=1000, E=\r\n, A=IPC $h + + The "E=\r\n" will save you headaches interoperating with such things as + VMS TCP products. + + The "L=1000" is for RFC821 compatibility. Not strictly necessary. + + I also removed the "s" (strip quotes) mailer flag Sun puts in for + these mailers. Stripping quotes violates protocols, which say + clearly that you can't touch the local-part (left hand side of + the @) until you are on the delivering host. + +NOW. If I haven't left anything out, you should be able to run through +your Sun sendmail.cf file and convert it to run under v8. + + BUILD ISSUES + +Some important notes on building v8 on SunOS: + +Makefile + +The default makefile in the version 8 source (src) directory assumes the +new Berkeley make. Unless you want to go to the trouble of building it, +you can use your regular make, but you need to use a different makefile. +You can use "Makefile.dist" or "Makefile.SunOS" in the src directory. I +made changes to get it to build so it is as compatible as possible with +the file/directory locations Sun uses. Here are some relevant sections +out of my makefile: + + CC=gcc + + # use O=-O (usual) or O=-g (debugging) + O= -O + + # define the database mechanisms available for map & alias lookups: + # -DNDBM -- use new DBM + # -DNEWDB -- use new Berkeley DB + # -DNDBM -DNEWDB -DYPCOMPAT -- use both plus YP compatility + # -DNIS -- include client NIS support + # The really old (V7) DBM library is no longer supported. + # See README for a description of how these flags interact. + #DBMDEF= -DNDBM -DNEWDB + DBMDEF= -DNDBM -DNIS + + # environment definitions (e.g., -D_AIX3) + ENVDEF= + + # see also conf.h for additional compilation flags + + # library directories + LIBDIRS=-L/usr/local/lib + + # libraries required on your system + #LIBS= -ldb -ldbm + LIBS= -ldbm -lresolv + + # location of sendmail binary (usually /usr/sbin or /usr/lib) + BINDIR= ${DESTDIR}/usr/lib + + # location of sendmail.st file (usually /var/log or /usr/lib) + STDIR= ${DESTDIR}/etc + + # location of sendmail.hf file (usually /usr/share/misc or /usr/lib) + HFDIR= ${DESTDIR}/usr/lib + +For the resolver library, you can use the one shipped with Sun if you +want. But I'd recommend using another version of the resolver library +(such as the one with Bind 4.8.3 or 4.9). Sun's resolver stuff (at +least with 4.1.x) is quite old - I believe it is of 4.3.1 vintage. (Do +you get the impression I don't TRUST what Sun ships with their systems?) + +If you want NIS host lookup while maintaining DNS capability, you might +take a look at resolv+, which has NIS capable gethostbyxxx() functions +in it. My recommendation, however, is to avoid doing NIS host lookups +in sendmail altogether, and to use a "pure" version of the resolver +library. + +There are probably no situations (at least I think so) where it makes +any sense to link in Sun's NIS gethostbyxxx() functions from libc. +You could, I guess do it (I haven't tried it) and wind up with a +sendmail equivalent to the non-mx version Sun ships. You'd need to +insure that NAMED_BIND is not defined in the build. (If you do +this and have the "-b" DNS passthru option set in NIS, remember that +while you have some DNS functionality you'll not have any MX support. +(This, IMO, is what makes this a non-optimal choice.) + + INSTALLATION/TESTING ISSUES + +The sendmail.hf file in the src directory should replace the one currently +in /usr/lib. You also might choose to edit it a bit to "localize" what it +says. + +The sendmail executable goes, of course, in /usr/lib in place of the current +one. What I did was create a subdirectory in /usr/lib and put all of the +Sun sendmail stuff in there. I named the v8 sendmail executable to be +sendmail.v8.mx and then symbolically linked it to sendmail. + +One other thing. If you use address test mode, keep in mind that +Version 8 is like IDA in that it does not automatically execute ruleset +3 first. So say you're playing around with things testing addresses and +you're used to things like: + + 0 jimbob@good.old.boy.com + +under v8 you need to say instead: + + 3,0 jimbob@good.old.boy.com + + INTEROPERABILITY ISSUES YOU MIGHT ENCOUNTER + +Be aware that sendmail v8 issues a multi-line SMTP welcome (220) +response upon a client connection. Most systems in your network should +handle it OK, but there are some that choke on it, because whoever wrote +the clients assumed only a single line. THIS IS NOT SENDMAIL's FAULT. +A multi-line 220 response is perfectly valid. A likely place you'll +encounter this problem is with non-Un*x SMTP clients. If you do run +into it, you should report it to the vendor. + +A final note about version 8 - if you follow the above configuration +scenario, you'll notice it doesn't like to get envelope sender +addresses it doesn't know how to get back to. Sun sendmail would take +anything, even though it might not be able to bounce the message back +should something happen downstream. So if another sendmail on a host +that's not locally known is trying to pump mail through your v8 host, +the ENVELOPE sender it gives had better be fully qualified. This is +a GREAT thing, because it helps clear up problems we've had with not +being able to get things back to the sender, resulting in an +overburdened postmaster. + +I hope this helps those running Sun sendmail feel more at ease with moving +on to v8.

It will keep +doing this until no further expansion is possible. +.SH OPTIONS +The default output of +.B expn +can contain many lines which are not valid +email addresses. With the +.I -aa +flag, only expansions that result in legal addresses +are used. Since many mailing lists have an illegal +address or two, the single +.IR -a , +address, flag specifies that a few illegal addresses can +be mixed into the results. More +.I -a +flags vary the ratio. Read the source to track down +the formula. With the +.I -a +option, you should be able to construct a new mailing +list out of an existing one. +.LP +If you wish to limit the number of levels deep that +.B expn +will recurse as it traces addresses, use the +.I -1 +option. For each +.I -1 +another level will be traversed. So, +.I -111 +will traverse no more than three levels deep. +.LP +The normal mode of operation for +.B expn +is to do all of its work silently. +The following options make it more verbose. +It is not necessary to make it verbose to see what it is +doing because as it works, it changes its +.BR argv [0] +variable to reflect its current activity. +To see how it is expanding things, the +.IR -v , +verbose, flag will cause +.B expn +to show each address before +and after translation as it works. +The +.IR -w , +watch, flag will cause +.B expn +to show you its conversations with the mail daemons. +Finally, the +.IR -d , +debug, flag will expose many of the inner workings so that +it is possible to eliminate bugs. +.SH ENVIRONMENT +No enviroment variables are used. +.SH FILES +.PD 0 +.B /tmp/expn$$ +.B temporary file used as input to +.BR nslookup . +.SH SEE ALSO +.BR aliases (5), +.BR sendmail (8), +.BR nslookup (8), +RFC 823, and RFC 1123. +.SH BUGS +Not all mail daemons will implement +.B expn +or +.BR vrfy . +It is not possible to verify addresses that are served +by such daemons. +.LP +When attempting to connect to a system to verify an address, +.B expn +only tries one IP address. Most mail daemons +will try harder. +.LP +It is assumed that you are running domain names and that +the +.BR nslookup (8) +program is available. If not, +.B expn +will not be able to verify many addresses. It will also pause +for a long time unless you change the code where it says +.I $have_nslookup = 1 +to read +.I $have_nslookup = +.IR 0 . +.LP +Lastly, +.B expn +does not handle every valid address. If you have an example, +please submit a bug report. +.SH CREDITS +In 1986 or so, Jon Broome wrote a program of the same name +that did about the same thing. It has since suffered bit rot +and Jon Broome has dropped off the face of the earth! +(Jon, if you are out there, drop me a line) +.SH AVAILABILITY +The latest version of +.B expn +is available through anonymous ftp at +.IR ftp://ftp.idiom.com/pub/muir-programs/expn . +.SH AUTHOR +.I David Muir Sharnoff\ \ \ \ diff --git a/contrib/sendmail/contrib/mail.local.linux b/contrib/sendmail/contrib/mail.local.linux new file mode 100644 index 000000000000..42d2c3c3d9ce --- /dev/null +++ b/contrib/sendmail/contrib/mail.local.linux @@ -0,0 +1,205 @@ +From: Karl London +Message-Id: <199308111712.SAA05454@borg.demon.co.uk> +Subject: Final port of mail.local to Linux +To: eric@cs.berkeley.edu +Date: Wed, 11 Aug 1993 18:12:27 +0100 (BST) +X-Mailer: ELM [version 2.4 PL21] +MIME-Version: 1.0 +Content-Type: text/plain; charset=US-ASCII +Content-Transfer-Encoding: 7bit +Content-Length: 11415 + +Hi, + Sorry about this..

It doesn't matter + what version of sendmail you're running. It doesn't matter + if you're not running sendmail (but it won't fix anything + for you). + + 2) No configuration file hacks. If the -client switch is + absent (the default), the new sendmails will get an EHLO + using what LocalName() returns as the hostname. On my systems, + this returns the FQDN. If the EHLO fails with a result between + 500 and 599 and the -client switch is not set, we give up on + sending EHLO/HELO and just go deliver the mail. + + 3) No new configuration options. + + 4) Retains the undocumented -client switch. One warning: it + is possible using the -client switch to cause the old sendmails + to return "I refuse to talk to myself". You could do this under + the old code as well. This will happen if you claim to be the + same system as the sendmail you're sending to is running on. + That's pointless, but possible. If you do this, just like under + the old code, you will get an error. + + 5) If you're running a site with both old and new sendmails, you only + have to build MH once. The code's the same; works with them + both. + + If you decide to install this, make sure that you look the patch +over and that you agree with what it is doing. It works for me, but I +can't test it on every possible combination. Make sure that it works +before you really install it for your users, if any. No promises. + + To install this, save this to a file in the mts/sendmail directory. +Feed it to patch. Patch will ignore the non-patch stuff. You should have +"mts sendmail/smtp" in your configuration file. This works with old and +new sendmails. Using "mts sendmail" will cause the new sendmails to +print an "X-auth..." warning about who owns the process piping the mail +message.

Introduction +--------------- +X +These tools may be of use to those sites using sendmail. Both are written in +Perl. Our site, Mot.COM, receives a ton of mail being a top-level domain +gateway. We have over 24 domains under us. Needless to say, we must have +a robust mail system or my head, and others, would be on the chopping block. +X +2. Description +-------------- +X +The first tool, cqueue, checks the sendmail queue for problems. We use +it to flag problems with subdomain mail servers (and even our own servers +once in a while ;-). We run it via a cron job every hour during the day. +You may find this too frequent, however. +X +The other program, postclip, is used to "filter" non-deliverable NDNs that +get sent to our Postmaster account now and then. This ensures privacy of +e-mail and helps avoid disk problems from huge NDNs. It is different than +a brute force "just keep the header" approach because it tries hard to keep +other parts of the message that look like non-delivery information. +X +Both have been used for some time at our site with no problems. Everything +you need should be in this distribution: source, manual pages, and support +libs. See the manual pages for a complete description of each tool. +X +3. Installation +--------------- +X +No fancy Makefile simply because these tools are all under a large +hierarchy at my site. Installation should be a snap, however. Install +the nroff(1) man(5) manual pages from the man subdirectory to the +appropriate directory on your system. This might be something like +/usr/local/man/man1. +X +Next, install all of the Perl libraries located in the lib subdirectory +to your Perl library area. /usr/local/lib/perl is a good bet. The person +who installed Perl at your site will be able to tell you for sure. +X +Finally, you need to install the programs. Note that cqueue wants to +run setuid root by default. This is because the sendmail queue is normally +only readable by root or some special group. In order to let any user +run this suidperl is used. suidperl allows a Perl program to run with the +privileges of another user. +X +You will have to edit both the cqueue and postclip programs to change +the #! line at the top of each. Just change the pathname to whatever is +appropriate on your system. Note that Larry Wall's fixin program from +the Camel book can also be used to do this. It is very handy. It changes +#! lines by looking at your PATH. +X +If you do not have suidperl on your system change the #! line in cqueue +to reference perl instead of suidperl. +X +You may also wish to change some constants in cqueue. $DEF_QUEUE should be +changed to your queue directory if it is not /usr/spool/mqueue. $DEF_TIME +could be changed easy enough also. It is the time spec for the time duration +after which a mail message will be reported on if the -a option has not been +specified. See the manual page for more information and the format of this +constant (same as the -t argument). Then again, neither of these has to +be changed. Command line options are there to override their default +values. +X +After you have edited the programs as necessary, all that remains is to +install them to some executable directory. Install postclip mode 555 +and cqueue mode 4555 with owner root (if using suidperl) or mode 555 +(if not using suidperl). +X +4. Gripes, Comments, Etc +------------------------ +X +If you start using either of these let me know. I have other mail tools I +will likely post in the future if these prove useful.

This is useful when +;# parsing a command line for your script while ignoring options that you +;# may pass to another script.

Only messages +that have a subject that begins with 'Returned mail:' are filtered. This +ensures that other mail is not accidently mucked with. Finally, note that +\fBsendmail\fR is used to deliver the message after it has been (possibly) +filtered. All of the original headers will remain intact. +.sp 1 +You can use this with any \fBsendmail\fR by modifying the Postmaster alias. +If you use IDA \fBsendmail\fR you could add the following to .m4: +.sp 1 +.RS +define(POSTMASTERBOUNCE, mailer-errors) +.RE +.sp 1 +In the aliases file, add a line similar to the following: +.sp 1 +.RS +mailer-errors: "|/usr/local/bin/postclip postmaster" +.RE +.SH OPTIONS +.IP \fB-v\fR +Be verbose about delivery.

MIME) +[RFC1521, RFC1344]. +Neither the IDA group nor most vendors +were modifying +.i sendmail +to conform to these new standards. +It seemed clear that these were ``good things'' +that should be encouraged. +However, since no one was working on a publically available version of +.i sendmail +with these updates, +they were unlikely to be widely deployed any time in the near future. +.pp +There are, of course, other mail transport agents available, +such as +.i MMDF +.\"[ref], +.i zmailer +.\"[ref], +.i smail +.\"[ref], +and +.i PP +.\"[ref]. +However, none of these seemed to be gaining the prominence of +.i sendmail ; +it appeared that most companies would not convert to another +mail transport agent any time in the forseeable future. +However, they might be persuaded to convert to a newer version of +.i sendmail . +.pp +All of these convinced the author +to work on a updated version of +.i sendmail +for public distribution. +.pp +The new version of +.i sendmail +is referred to as version eight (V8). +Versions six and seven were skipped +because of an agreement +that all files in 4.4BSD would be numbered as +.q 8.1 . +Rather than have an external version number +that differed from the file version numbers, +.i sendmail +just jumped directly to V8. +.sh 1 "CHANGES IN VERSION EIGHT" +.pp +The following is a summary of the changes between the last commonly +available version of sendmail from Berkeley (5.67) and the latest +version (8.6.6). +.pp +Many of these are ideas that had been tried in IDA, +but many of them were generalized in V8. +.sh 2 "Performance Enhancements" +.pp +Instead of closing SMTP connections immediately, open connections are +cached for possible future use. There is a limit to the number of +simultaneous open connections and the idle time of any individual +connection. +.pp +This is of best help during queue processing (since there is the +potential of many different messages going to one site), although +it can also help when processing MX records which aren't handled +by MX Piggybacking. +.pp +If two hosts with different names in a single message happen to +have the same set of MX hosts, they can be sent in the same +transaction. Version 8 notices this and tries to batch the messages. +.pp +For example, if two sites ``foo.com'' and ``bar.com'' are both +served by UUNET, they will have the same set of MX hosts and will +be sent in one transaction. UUNET will then split the message +and send it to the two individual hosts. +.sh 2 "RFC 1123 Changes" +.pp +A number of changes have been made to make sendmail ``conditionally +compliant'' (that is, it satisfies all of the MUST clauses and most +but not all of the SHOULD clauses in RFC 1123). +.pp +The major areas of change are (numbers are RFC 1123 section numbers): +.nr ii 0.75i +.ip \(sc5.2.7 +Response to RCPT command is fast. Previously, sendmail +expanded all aliases as far as it could \*- this could +take a very long time, particularly if there were +name server delays. Version 8 only checks for the +existence of an alias and does the expansion later. +It does still do a DNS lookup if there is an explicit host name +in the RCPT command, +but this time is bounded. +.ip \(sc5.2.8 +Numeric IP addresses are logged in Received: lines. +This helps tracing spoofed messages. +.ip \(sc5.2.17 +Self domain literal is properly handled. Previously, +if someone sent to user@[1.2.3.4], where 1.2.3.4 is +your IP address, the mail would probably be rejected +with a ``configuration error''. +Version 8 can handle these addresses. +.ip \(sc5.3.2 +Better control over individual timeouts. RFC 821 specified +no timeouts. Older versions of sendmail had a single +timeout, typically set to two hours. Version 8 allows +the configuration file to set timeouts for various +SMTP commands individually. +.ip \(sc5.3.3 +Error messages are sent as From:<>. This was urged by +RFC 821 and reiterated by RFC 1123, but older versions +of sendmail never really did it properly. Version 8 +does. However, some systems cannot handle this +perfectly legal address; if necessary, you can create +a special mailer that uses the `g' flag to disable this. +.ip \(sc5.3.3 +Error messages are never sent to <>. Previously, +sendmail was happy to send responses-to-responses which +sometimes resulted in responses-to-responses-to-responses +which resulted in .... you get the idea. +.ip \(sc5.3.3 +Route-addrs (the ugly ``<@hosta,@hostb:user@hostc>'' +syntax) are pruned. RFC 821 urged the use of this +bletcherous syntax. RFC 1123 has seen the light and +officially deprecates them, further urging that you +eliminate all but ``user@hostc'' should you receive +one of these things. Version 8 is slightly more generous +than the standards suggest; instead of stripping off all +the route addressees, it only strips hosts off up to +the one before the last one known to DNS, thus allowing +you to have pseudo-hosts such as foo.BITNET. The `R' +option will turn this off. +.lp +The areas in which sendmail is not ``unconditionally compliant'' are: +.ip \(sc5.2.6 +Sendmail does do header munging. +.ip \(sc5.2.10 +Sendmail doesn't always use the exact SMTP message +text from RFC 821. This is a rather silly requirement. +.ip \(sc5.3.1.1 +Sendmail doesn't guarantee only one connect for each +host on queue runs. Connection caching gives you most +of this, but it does not provide a guarantee. +.ip \(sc5.3.1.1 +Sendmail doesn't always provide an adequate limit +on concurrency. That is, there can be several +independent sendmails running at once. My feeling +is that doing an absolute limit would be a mistake +(it might result in lost mail). However, if you use +the XLA contributed software, most of this will be +guaranteed (but I don't guarantee the guarantee). +.sh 2 "Extended SMTP Support +.pp +Version 8 includes both sending and receiving support for Extended +SMTP support as defined by RFC 1425 (basic) and RFC 1427 (SIZE); +and limited support for RFC 1426 (BODY). +The body support is minimal because the +.q 8BITMIME +body type is not currently advertised. +Although such a body type will be accepted, +it will not be correctly converted to 7 bits +if speaking to a non-8-bit-MIME aware SMTP server. +.pp +.i Sendmail +tries to speak ESMTP if you have the `a' flag set +in the flags for the mailer descriptor, +or if the other end advertises the fact that it speaks ESMTP. +This is a non-standard advertisement: +.i sendmail +announces +.q "ESMTP spoken here" +during the initial connection message, +and client sendmails search for this message. +This creates some problems for some PC-based mailers, +which do not understand two-line greeting messages +as required by RFC 821. +.sh 2 "Eight-Bit Clean +.pp +Previous versions of sendmail used the 0200 bit for quoting. This +version avoids that use. +However, you can set option `7' to get seven bit stripping +for compatibility with RFC 821, +which is a 7-bit protocol. +This option says ``strip to 7 bits on input''. +.pp +Individual mailers can still produce seven bit out put using the +`7' mailer flag. +This flag says ``strip to 7 bits on output''. +.sh 2 "User Database" +.pp +The User Database (UDB) is an as-yet experimental attempt to provide +unified large-site name support. +We are installing it at Berkeley; +future versions may show significant modifications. +Briefly, UDB contains a database that is intended to contain +all the per-user information for your workgroup, +such as people's full names, their .plan information, +their outgoing mail name, and their mail drop. +.pp +The user database allows you to map both incoming and outgoing +addresses, much like IDA. However, the interface is still +better with IDA; +in particular, the alias file with incoming/outgoing marks +provides better locality of information. +.sh 2 "Improved BIND Support" +.pp +The BIND support, particularly for MX records, had a number of +annoying ``features'' which have been removed in this release. In +particular, these more tightly bind (pun intended) the name server +to sendmail, so that the name server resolution rules are incorporated +directly into sendmail. +.pp +The major change has been that the $[ ... $] operator didn't fully +qualify names that were in DNS as A or MX records. Version 8 does +this qualification. +.pp +This has proven to be an annoyance in Sun shops, +who often still run without BIND support. +However, it is really critical that this be supported, +since MX records are mandatory. +In SunOS you can choose either MX support or NIS support, +but not both. +This is fixed in Solaris, +and some +.i sendmail +support to allow this in SunOS should be forthcoming in a future release. +.sh 2 "Keyed Files" +.pp +Generalized keyed files is an idea taken directly from IDA sendmail +(albeit with a completely different implementation). +They can be useful on large sites. +.pp +Version 8 includes the following built-in map classes: +.ip dbm +Support for the ndbm(3) library. +.ip hash +Support for the ``Hash'' type from the new Berkeley db(3) library. +this library provides substantially better database support +than ndbm(3), +including in-memory caching, +arbitrarily long keys and values, +and better disk utilization. +.ip btree +Support for the ``B-Tree'' type from the new Berkeley db(3) library. +B-Trees provide better clustering than Hashed files +if you are fetching lots of records that have similar keys, +such as searching a dictionary for words beginning with ``detr''. +.ip nis +Support for NIS (a.k.a. YP) maps. +NIS+ is not supported in this version. +.ip host +Support for DNS lookups. +.ip dequote +A ``pseudo-map'' (that is, once that does not have any external data) +that allows a configuration file to break apart a quoted string +in the address. +This is necessary primarily for DECnet addresses, +which often have quoted addresses that need to be unwrapped on gateways. +.sh 2 "Multi-Word Classes & Macros in Classes" +.pp +Classes can now be multiple words. For example, +.(b +CShofmann.CS.Berkeley.EDU +.)b +allows you to match the entire string ``hofmann.CS.Berkeley.EDU'' +using the single construct ``$=S''. +.pp +Class definitions are now allowed to include macros \*- for example: +.(b +Cw$k +.)b +is legal. +.sh 2 "IDENT Protocol Support" +.pp +The IDENT protocol as defined in RFC 1413 [RFC1413] is supported. +However, many systems have a TCP/IP bug that renders this useless, +and the feature must be turned off. +Roughly, if one of these system receives a +.q "No route to host" +message (ICMP message ICMP_UNREACH_HOST) on +.i any +connection, all connections to that host are closed. +Some firewalls return this error if you try to connect +to the IDENT port, +so you can't receive email from these hosts on these systems. +It's possible that if the firewall used a more specific message +(such as ICMP_UNREACH_PROTOCOL, ICMP_UNREACH_PORT or ICMP_UNREACH_NET_PROHIB) +it would work, but this hasn't been verified. +.pp +IDENT protocol support cannot be used on +4.3BSD, +Apollo DomainOS, +Apple A/UX, +ConvexOS, +Data General DG/UX, +HP-UX, +Sequent Dynix, +or +Ultrix 4.x, x \(<= 3. +It seems to work on +4.4BSD, +IBM AIX 3.x, +OSF/1, +SGI IRIX, +Solaris, +SunOS, +and Ultrix 4.4. +.sh 2 "Separate Envelope/Header Processing +.pp +Since the From: line is passed in separately from the envelope +sender, these have both been made visible; the $g macro is set to +the envelope sender during processing of mailer argument vectors +and the header sender during processing of headers. +.pp +It is also possible to specify separate per-mailer envelope and +header processing. The SenderRWSet and RecipientRWset arguments +for mailers can be specified as ``envelope/header'' to give different +rewritings for envelope versus header addresses. +.sh 2 "Owner-List Propagates to Envelope +.pp +When an alias has an associated owner-list name, that alias is used +to change the envelope sender address. This will cause downstream +errors to be returned to that owner. +.pp +Some people find this confusing +because the envelope sender is what appears in the first +``From_'' line in UNIX messages +(that is, the line beginning ``From'' +instead of ``From:''; +the latter is the header from, which +.i does +indicate the sender of the message). +In previous versions, +.i sendmail +has tried to avoid changing the envelope sender +for back compatibility with UNIX convention; +at this point that back compatibility is creating too many problems, +and it is necessary to move forward into the 1980s. +.sh 2 "Command Line Flags" +.pp +The +.b \-B +flag has been added to pass in body type information. +.pp +The +.b \-p +flag has been added to pass in protocol information +that was previously passed in by defining the +.b $r +and +.b $s +macros. +.pp +The +.b \-X +flag has been added to allow logging of all protocol in and +out of sendmail for debugging. +You can set +.q "\-X filename" +and a complete transcript will be logged in that file. +This gets big fast: the option is only for debugging. +.pp +The +.b \-q +flag can limit limit a queue run to specific recipients, +senders, or queue ids using \-qRsubstring, \-qSsubstring, or +\-qIsubstring respectively. +.sh 2 "New Configuration Line Types +.pp +The `T' (Trusted users) configuration line has been deleted. It +will still be accepted but will be ignored. +.pp +The `K' line has been added to declare database maps. +.pp +The `V' line has been added to declare the configuration version +level. +.pp +The `M' (mailer) line takes a D= field to specify execution +directory. +.sh 2 "New and Extended Options" +.pp +Several new options have been added, many to support new features, +others to allow tuning that was previously available only by +recompiling. Briefly: +.nr ii 0.5i +.ip A +The alias file specification can now be a list of alias files. +Also, the configuration can specify a class of file. +For example, to search the NIS aliases, use +.q OAnis:mail.aliases . +.ip b +Insist on a minimum number of disk blocks. +.ip C +Delivery checkpoint interval. Checkpoint the queue (to avoid +duplicate deliveries) every C addresses. +.ip E +Default error message. This message (or the contents of the +indicated file) are prepended to error messages. +.ip G +Enable GECOS matching. If you can't find a local user name +and this option is enabled, do a sequential scan of the passwd +file to match against full names. Previously a compile option. +.ip h +Maximum hop count. Previously this was compiled in. +.ip I +This option has been extended to allow setting of resolver parameters. +.ip j +Send errors in MIME-encapsulated format. +.ip J +Forward file path. Where to search for .forward files \*- defaults +to $HOME/.forward. +.ip k +Connection cache size. The total number of connections that will +be kept open at any time. +.ip K +Connection cache lifetime. The amount of time any connection +will be permitted to sit idle. +.ip l +Enable Errors-To: header. These headers violate RFC 1123; +this option is included to provide back compatibility with +old versions of sendmail. +.ip O +Incoming daemon options (e.g., use alternate SMTP port). +.ip p +Privacy options. These can be used to make your SMTP server +less friendly. +.ip r +This option has been extended to allow finer grained control +over timeouts. +For example, you can set the timeout for SMTP commands individually. +.ip R +Don't prune route-addrs. Normally, if version 8 sees an address +like "<@hostA,@hostB:user@hostC>, sendmail will try to strip off +as much as it can (up to user@hostC) as suggested by RFC 1123. +This option disables that behaviour. +.ip T +The +.q "Return To Sender" +timeout has been extended +to allow specification of a warning message interval, +typically something on the order of four hours. +If a message cannot be delivered in that interval, +a warning message is sent back to the sender +but the message continues to be tried. +.ip U +User database spec. This is still experimental. +.ip V +Fallback ``MX'' host. This can be thought of as an MX host +that applies to all addresses that has a very high preference +value (that is, use it only if everything else fails). +.ip w +If set, assume that if you are the best MX host for a host, +you should send directly to that host. This is intended +for compatibility with UIUC sendmail, and may have some +use on firewalls. +.ip 7 +Do not run eight bit clean. Technically, you have to assert +this option to be RFC 821 compatible. +.sh 2 "New Mailer Definitions" +.ip L= +Set the allowable line length. In V5, the L mailer flag implied +a line length limit of 990 characters; this is now settable to +an arbitrary value. +.ip F=a +Try to use ESMTP. It will fall back to SMTP if the initial +EHLO packet is rejected. +.ip F=b +Ensure a blank line at the end of messages. Useful on the +*file* mailer. +.ip F=c +Strip all comments from addresses; this should only be used as +a last resort when dealing with cranky mailers. +.ip F=g +Never use the null sender as the envelope sender, even when +running SMTP. This violates RFC 1123. +.ip F=7 +Strip all output to this mailer to 7 bits. +.ip F=L +Used to set the line limit to 990 bytes for SMTP compatibility. +It now does that only if the L= keyletter is not specified. +This flag is obsolete and should not be used. +.sh 2 "New or Changed Pre-Defined Macros" +.ip $k +UUCP node name from uname(2). +.ip $m +Domain part of our full hostname. +.ip $_ +RFC 1413-provided sender address. +.ip $w +Previously was sometimes the full domain name, sometimes +just the first word. Now guaranteed to be the first word +of the domain name (i.e., the host name). +.ip $j +Previously had to be defined \*- it is now predefined to be +the full domain name, if that can be determined. That is, +it is equivalent to $w.$m. +.sh 2 "New and Changed Classes" +.ip $=k +Initialized to contain $k. +.ip $=w +Now includes +.q [1.2.3.4] +(where 1.2.3.4 is your IP address) +to allow the configuration file to recognize your own IP address. +.sh 2 "New Rewriting Tokens" +.pp +The +.b $& +construct has been adopted from IDA to defer macro evaluation. +Normally, macros in rulesets are bound when the rule is first parsed +during startup. +Some macros change during processing and are uninteresting during startup. +However, that macro can be referenced using +.q $&x +to defer the evaulation of +$x +until the rule is processed. +.pp +The tokens +.b $( +and +.b $) +have been added to allow specification of map rewriting. +.pp +Version 8 allows +.b $@ +on the Left Hand Side of an `R' line to match +zero tokens. +This is intended to be used to match the null input. +.sh 2 "Bigger Defaults +.pp +Version 8 allows up to 100 rulesets instead of 30. It is recommended +that rulesets 0\-9 be reserved for sendmail's dedicated use in future +releases. +.pp +The total number of MX records that can be used has been raised to +20. +.pp +The number of queued messages that can be handled at one time has +been raised from 600 to 1000. +.sh 2 "Different Default Tuning Parameters +.pp +Version 8 has changed the default parameters for tuning queue costs +to make the number of recipients more important than the size of +the message (for small messages). This is reasonable if you are +connected with reasonably fast links. +.sh 2 "Auto-Quoting in Addresses +.pp +Previously, the ``Full Name '' syntax would generate +incorrect protocol output if ``Full Name'' had special characters +such as dot. This version puts quotes around such names. +.sh 2 "Symbolic Names On Error Mailer +.pp +Several names have been built in to the $@ portion of the $#error +mailer. For example: +.(b +$#error $@NOHOST $: Host unknown +.)b +Prints the indicated message +and sets the exit status of +.i sendmail +to +.sm EX_NOHOST . +.sh 2 "New Built-In Mailers" +.pp +Two new mailers, *file* and *include*, are included to define options +when mailing to a file or a :include: file respectively. Previously +these were overloaded on the local mailer. +.sh 2 "SMTP VRFY Doesn't Expand +.pp +Previous versions of sendmail treated VRFY and EXPN the same. In +this version, VRFY doesn't expand aliases or follow .forward files. +.pp +As an optimization, if you run with your default delivery mode +being queue-only, the RCPT command will also not chase aliases and +\&.forward files. +It will chase them when it processes the queue. +This speeds up RCPT processing. +.sh 2 "[IPC] Mailers Allow Multiple Hosts +.pp +When an address resolves to a mailer that has ``[IPC]'' as its +``Path'', the $@ part (host name) can be a colon-separated list of +hosts instead of a single hostname. This asks sendmail to search +the list for the first entry that is available exactly as though +it were an MX record. The intent is to route internal traffic +through internal networks without publishing an MX record to the +net. MX expansion is still done on the individual items. +.sh 2 "Aliases Extended" +.pp +The implementation has been merged with maps. Among other things, +this supports multiple alias files and NIS-based aliases. For +example: +.(b +OA/etc/aliases,nis:mail.aliases +.)b +will search first the local database +.q /etc/aliases +followed by the NIS map + +.sh 2 "Portability and Security Enhancements +.pp +A number of internal changes have been made to enhance portability. +.pp +Several fixes have been made to increase the paranoia factor. +.pp +In particular, the permissions required for .forward and :include: +files have been tightened up considerably. V5 would pretty much +read any file it could get to as root, which exposed some security +holes. V8 insists that all directories leading up to the .forward +or :include: file be searchable ("x" permission) by the controlling +user" (defined below), that the file itself be readable by the +controlling user, and that .forward files be owned by the user +who is being forwarded to or root. +.pp +The "controlling user" is the user on whose behalf the mail is +being delivered. For example, if you mail to "user1" then the +controlling user for ~user1/.forward and any mailers invoked +by that .forward file, including :include: files. +.pp +Previously, anyone who had a home directory could create a .forward +could forward to a program. Now, sendmail checks to make sure +that they have an "approved shell", that is, a shell listed in +the /etc/shells file. +.sh 2 "Miscellaneous Fixes and Enhancements" +.pp +A number of small bugs having to do with things like backslash-escaped +quotes inside of comments have been fixed. +.pp +The fixed size limit on header lines +(such as +.q To: +and +.q Cc: ) +has been eliminated; +those buffers are dynamically allocated now. +.pp +Sendmail writes a /etc/sendmail.pid file with the current process id +and the current invocation flags. +.pp +Two people using the same program (e.g., submit) are considered +"different" so that duplicate elimination doesn't delete one of +them. For example, two people forwarding their email to +|submit will be treated as two recipients. +.pp +The mailstats program prints mailer names and gets the location of +the sendmail.st file from /etc/sendmail.cf. +.pp +Many minor bugs have been fixed, such as handling of backslashes +inside of quotes. +.pp +A hook has been added to allow rewriting of local addresses after +aliasing. +.sh 1 "FUTURE WORK" +.pp +The previous section describes +.i sendmail +as of version 8.6.6. +There is still much to be done. +Some high points are described below. +This list is by no means exhaustive. +.sh 2 "Full MIME Support" +.pp +Currently +.i sendmail +only supports seven bit MIME messages. +Although it can pass eight bit MIME messages, +it cannot advertise that fact because the standards say +that the mail agent must be able to do 8- to 7-bit conversion +to have full 8-bit support. +This requires far more extensive modification of the message body +than is currently supported. +.pp +The best way to do this would be to support the general concept +of an external +``message filter'' +that could do arbitrary modifications of the message. +This would allow MIME conversion as well as such things as +automatic encryption of messages sent over external links. +This is probably an extremely non-trivial change. +.sh 2 "Service Switch Abstraction" +.pp +Most modern systems include some concept of a +.q "service switch" +\*- for example, to look up host names you can try +DNS, NIS, NIS+, text tables, NetInfo, +or other services in some arbitrary order. +This is currently very clumsy in +.i sendmail , +with only limited control of the services provided. +.sh 2 "More Control of Local Addresses" +.pp +Currently some addresses are declared as +.q local +and are handled specially \*- +for example, they may have .forward files, +may be translated into program calls or file deliveries, +and so forth. +These should be broken out into separate flags +to allow the local system administrator +to have more fine-grained control over operations. +.sh 2 "More Run-Time Configuration Options" +.pp +There are many options that are configured at compile time, +such as the method of file locking +and the use of the IDENT protocol +[RFC1413]. +These should be transfered to run time +by adding new options. +.pp +Similarly, some options are currently overloaded, +that is, a single option controls more than one thing. +These should probably be broken out into separate options. +.pp +This implies that options will change from single characters +to words. +.sh 2 "More Configuration Control Over Errors" +.pp +Currently, +the configuration file can generate an error message during parsing. +However, +it cannot tweak other operations, +such as issuing a warning message to the system postmaster. +Similarly, +some errors should not be triggered if they are in aliases +during an alias file rebuild, +but should be triggered if that alias is actually used. +.sh 2 "Long Term Host State" +.pp +Currently, +.i sendmail +only remembers host status during a single queue run. +This should be converted to long term status +stored on disk +so it can be shared between instantiations of +.i sendmail . +Entries will have to be timestamped +so they can time out. +This will allow +.i sendmail +to implement exponential backoff on queue runs +on a per-host basis. +.sh 2 "Connection Control" +.pp +Modern networks have different types of connectivity +than the past. +In particular, the rising prominence of dialup IP +has created certain challenges for automated servers. +It is not uncommon to try to make a connection to a host +and have it fail, even though if you tried again it would succeed. +The connection management could be a bit cleverer +to try to adapt to such situations. +.sh 2 "Other Caching" +.pp +When you do an MX record lookup, +the name server automatically returns the IP addresses +of the associated MX servers. +This information is currently ignored, +and another query is done to get this information. +It should be cached to avoid excess name server traffic. +.sh 1 "REFERENCES" +.ip [Allman83a] +.q "Sendmail \*- An Internetwork Mail Router." +E.

Among the worst of these is that of address mapping. +Historically, this has been handled on an +.i "ad hoc" +basis. However, +this approach has become unmanageable as internets grow. +.sp \n(psu +Sendmail acts a unified "post office" to which all mail can be +submitted. Address interpretation is controlled by a production +system, which can parse both domain-based addressing and old-style +.i "ad hoc" +addresses. +The production system is powerful +enough to rewrite addresses in the message header to conform to the +standards of a number of common target networks, including old +(NCP/RFC733) Arpanet, new (TCP/RFC822) Arpanet, UUCP, and Phonenet. +Sendmail also implements an SMTP server, message +queueing, and aliasing. +.)l +.sp 2 +.(f +*A considerable part of this work +was done while under the employ +of the INGRES Project +at the University of California at Berkeley +and at Britton Lee. +.)f +.pp +.i Sendmail +implements a general internetwork mail routing facility, +featuring aliasing and forwarding, +automatic routing to network gateways, +and flexible configuration. +.pp +In a simple network, +each node has an address, +and resources can be identified +with a host-resource pair; +in particular, +the mail system can refer to users +using a host-username pair. +Host names and numbers have to be administered by a central authority, +but usernames can be assigned locally to each host. +.pp +In an internet, +multiple networks with different characterstics +and managements +must communicate. +In particular, +the syntax and semantics of resource identification change. +Certain special cases can be handled trivially +by +.i "ad hoc" +techniques, +such as +providing network names that appear local to hosts +on other networks, +as with the Ethernet at Xerox PARC. +However, the general case is extremely complex. +For example, +some networks require point-to-point routing, +which simplifies the database update problem +since only adjacent hosts must be entered +into the system tables, +while others use end-to-end addressing. +Some networks use a left-associative syntax +and others use a right-associative syntax, +causing ambiguity in mixed addresses. +.pp +Internet standards seek to eliminate these problems. +Initially, these proposed expanding the address pairs +to address triples, +consisting of +{network, host, resource} +triples. +Network numbers must be universally agreed upon, +and hosts can be assigned locally +on each network. +The user-level presentation was quickly expanded +to address domains, +comprised of a local resource identification +and a hierarchical domain specification +with a common static root. +The domain technique +separates the issue of physical versus logical addressing. +For example, +an address of the form +.q "eric@a.cc.berkeley.arpa" +describes only the logical +organization of the address space. +.pp +.i Sendmail +is intended to help bridge the gap +between the totally +.i "ad hoc" +world +of networks that know nothing of each other +and the clean, tightly-coupled world +of unique network numbers. +It can accept old arbitrary address syntaxes, +resolving ambiguities using heuristics +specified by the system administrator, +as well as domain-based addressing. +It helps guide the conversion of message formats +between disparate networks. +In short, +.i sendmail +is designed to assist a graceful transition +to consistent internetwork addressing schemes. +.sp +.pp +Section 1 discusses the design goals for +.i sendmail . +Section 2 gives an overview of the basic functions of the system. +In section 3, +details of usage are discussed. +Section 4 compares +.i sendmail +to other internet mail routers, +and an evaluation of +.i sendmail +is given in section 5, +including future plans. +.sh 1 "DESIGN GOALS" +.pp +Design goals for +.i sendmail +include: +.np +Compatibility with the existing mail programs, +including Bell version 6 mail, +Bell version 7 mail +[UNIX83], +Berkeley +.i Mail +[Shoens79], +BerkNet mail +[Schmidt79], +and hopefully UUCP mail +[Nowitz78a, Nowitz78b]. +ARPANET mail +[Crocker77a, Postel77] +was also required. +.np +Reliability, in the sense of guaranteeing +that every message is correctly delivered +or at least brought to the attention of a human +for correct disposal; +no message should ever be completely lost. +This goal was considered essential +because of the emphasis on mail in our environment. +It has turned out to be one of the hardest goals to satisfy, +especially in the face of the many anomalous message formats +produced by various ARPANET sites. +For example, +certain sites generate improperly formated addresses, +occasionally +causing error-message loops. +Some hosts use blanks in names, +causing problems with +UNIX mail programs that assume that an address +is one word. +The semantics of some fields +are interpreted slightly differently +by different sites. +In summary, +the obscure features of the ARPANET mail protocol +really +.i are +used and +are difficult to support, +but must be supported. +.np +Existing software to do actual delivery +should be used whenever possible. +This goal derives as much from political and practical considerations +as technical. +.np +Easy expansion to +fairly complex environments, +including multiple +connections to a single network type +(such as with multiple UUCP or Ether nets +[Metcalfe76]). +This goal requires consideration of the contents of an address +as well as its syntax +in order to determine which gateway to use. +For example, +the ARPANET is bringing up the +TCP protocol to replace the old NCP protocol. +No host at Berkeley runs both TCP and NCP, +so it is necessary to look at the ARPANET host name +to determine whether to route mail to an NCP gateway +or a TCP gateway. +.np +Configuration should not be compiled into the code. +A single compiled program should be able to run as is at any site +(barring such basic changes as the CPU type or the operating system). +We have found this seemingly unimportant goal +to be critical in real life. +Besides the simple problems that occur when any program gets recompiled +in a different environment, +many sites like to +.q fiddle +with anything that they will be recompiling anyway. +.np +.i Sendmail +must be able to let various groups maintain their own mailing lists, +and let individuals specify their own forwarding, +without modifying the system alias file. +.np +Each user should be able to specify which mailer to execute +to process mail being delivered for him. +This feature allows users who are using specialized mailers +that use a different format to build their environment +without changing the system, +and facilitates specialized functions +(such as returning an +.q "I am on vacation" +message). +.np +Network traffic should be minimized +by batching addresses to a single host where possible, +without assistance from the user. +.pp +These goals motivated the architecture illustrated in figure 1. +.(z +.hl +.ie t \ +\{\ +.ie !"\*(.T"" \ +\{\ +.PS

with a mail generating and sending program. +When the mail is created, +the generator calls +.i sendmail , +which routes the message to the correct mailer(s). +Since some of the senders may be network servers +and some of the mailers may be network clients, +.i sendmail +may be used as an internet mail gateway. +.sh 1 "OVERVIEW" +.sh 2 "System Organization" +.pp +.i Sendmail +neither interfaces with the user +nor does actual mail delivery. +Rather, +it collects a message +generated by a user interface program (UIP) +such as Berkeley +.i Mail , +MS +[Crocker77b], +or MH +[Borden79], +edits the message as required by the destination network, +and calls appropriate mailers +to do mail delivery or queueing for network transmission\**. +.(f +\**except when mailing to a file, +when +.i sendmail +does the delivery directly. +.)f +This discipline allows the insertion of new mailers +at minimum cost. +In this sense +.i sendmail +resembles the Message Processing Module (MPM) +of [Postel79b]. +.sh 2 "Interfaces to the Outside World" +.pp +There are three ways +.i sendmail +can communicate with the outside world, +both in receiving and in sending mail. +These are using the conventional UNIX +argument vector/return status, +speaking SMTP over a pair of UNIX pipes, +and speaking SMTP over an interprocess(or) channel. +.sh 3 "Argument vector/exit status" +.pp +This technique is the standard UNIX method +for communicating with the process. +A list of recipients is sent in the argument vector, +and the message body is sent on the standard input. +Anything that the mailer prints +is simply collected and sent back to the sender +if there were any problems. +The exit status from the mailer is collected +after the message is sent, +and a diagnostic is printed if appropriate. +.sh 3 "SMTP over pipes" +.pp +The SMTP protocol +[Postel82] +can be used to run an interactive lock-step interface +with the mailer. +A subprocess is still created, +but no recipient addresses are passed to the mailer +via the argument list. +Instead, they are passed one at a time +in commands sent to the processes standard input. +Anything appearing on the standard output +must be a reply code +in a special format. +.sh 3 "SMTP over an IPC connection" +.pp +This technique is similar to the previous technique, +except that it uses a 4.2bsd IPC channel +[UNIX83]. +This method is exceptionally flexible +in that the mailer need not reside +on the same machine. +It is normally used to connect to a sendmail process +on another machine. +.sh 2 "Operational Description" +.pp +When a sender wants to send a message, +it issues a request to +.i sendmail +using one of the three methods described above. +.i Sendmail +operates in two distinct phases. +In the first phase, +it collects and stores the message. +In the second phase, +message delivery occurs. +If there were errors during processing +during the second phase, +.i sendmail +creates and returns a new message describing the error +and/or returns an status code +telling what went wrong. +.sh 3 "Argument processing and address parsing" +.pp +If +.i sendmail +is called using one of the two subprocess techniques, +the arguments +are first scanned +and option specifications are processed. +Recipient addresses are then collected, +either from the command line +or from the SMTP +RCPT command, +and a list of recipients is created. +Aliases are expanded at this step, +including mailing lists. +As much validation as possible of the addresses +is done at this step: +syntax is checked, and local addresses are verified, +but detailed checking of host names and addresses +is deferred until delivery. +Forwarding is also performed +as the local addresses are verified. +.pp +.i Sendmail +appends each address +to the recipient list after parsing. +When a name is aliased or forwarded, +the old name is retained in the list, +and a flag is set that tells the delivery phase +to ignore this recipient. +This list is kept free from duplicates, +preventing alias loops +and duplicate messages deliverd to the same recipient, +as might occur if a person is in two groups. +.sh 3 "Message collection" +.pp +.i Sendmail +then collects the message. +The message should have a header at the beginning. +No formatting requirements are imposed on the message +except that they must be lines of text +(i.e., binary data is not allowed). +The header is parsed and stored in memory, +and the body of the message is saved +in a temporary file. +.pp +To simplify the program interface, +the message is collected even if no addresses were valid. +The message will be returned with an error. +.sh 3 "Message delivery" +.pp +For each unique mailer and host in the recipient list, +.i sendmail +calls the appropriate mailer. +Each mailer invocation sends to all users receiving the message on one host. +Mailers that only accept one recipient at a time +are handled properly. +.pp +The message is sent to the mailer +using one of the same three interfaces +used to submit a message to sendmail. +Each copy of the message is +prepended by a customized header. +The mailer status code is caught and checked, +and a suitable error message given as appropriate. +The exit code must conform to a system standard +or a generic message +(\c +.q "Service unavailable" ) +is given. +.sh 3 "Queueing for retransmission" +.pp +If the mailer returned an status that +indicated that it might be able to handle the mail later, +.i sendmail +will queue the mail and try again later. +.sh 3 "Return to sender" +.pp +If errors occur during processing, +.i sendmail +returns the message to the sender for retransmission. +The letter can be mailed back +or written in the file +.q dead.letter +in the sender's home directory\**. +.(f +\**Obviously, if the site giving the error is not the originating +site, the only reasonable option is to mail back to the sender. +Also, there are many more error disposition options, +but they only effect the error message \*- the +.q "return to sender" +function is always handled in one of these two ways. +.)f +.sh 2 "Message Header Editing" +.pp +Certain editing of the message header +occurs automatically. +Header lines can be inserted +under control of the configuration file. +Some lines can be merged; +for example, +a +.q From: +line and a +.q Full-name: +line can be merged under certain circumstances. +.sh 2 "Configuration File" +.pp +Almost all configuration information is read at runtime +from an ASCII file, +encoding +macro definitions +(defining the value of macros used internally), +header declarations +(telling sendmail the format of header lines that it will process specially, +i.e., lines that it will add or reformat), +mailer definitions +(giving information such as the location and characteristics +of each mailer), +and address rewriting rules +(a limited production system to rewrite addresses +which is used to parse and rewrite the addresses). +.pp +To improve performance when reading the configuration file, +a memory image can be provided. +This provides a +.q compiled +form of the configuration file. +.sh 1 "USAGE AND IMPLEMENTATION" +.sh 2 "Arguments" +.pp +Arguments may be flags and addresses. +Flags set various processing options. +Following flag arguments, +address arguments may be given, +unless we are running in SMTP mode. +Addresses follow the syntax in RFC822 +[Crocker82] +for ARPANET +address formats. +In brief, the format is: +.np +Anything in parentheses is thrown away +(as a comment). +.np +Anything in angle brackets (\c +.q "<\|>" ) +is preferred +over anything else. +This rule implements the ARPANET standard that addresses of the form +.(b +user name +.)b +will send to the electronic +.q machine-address +rather than the human +.q "user name." +.np +Double quotes +(\ "\ ) +quote phrases; +backslashes quote characters. +Backslashes are more powerful +in that they will cause otherwise equivalent phrases +to compare differently \*- for example, +.i user +and +.i +"user" +.r +are equivalent, +but +.i \euser +is different from either of them. +.pp +Parentheses, angle brackets, and double quotes +must be properly balanced and nested. +The rewriting rules control remaining parsing\**. +.(f +\**Disclaimer: Some special processing is done +after rewriting local names; see below. +.)f +.sh 2 "Mail to Files and Programs" +.pp +Files and programs are legitimate message recipients. +Files provide archival storage of messages, +useful for project administration and history. +Programs are useful as recipients in a variety of situations, +for example, +to maintain a public repository of systems messages +(such as the Berkeley +.i msgs +program, +or the MARS system +[Sattley78]). +.pp +Any address passing through the initial parsing algorithm +as a local address +(i.e, not appearing to be a valid address for another mailer) +is scanned for two special cases. +If prefixed by a vertical bar (\c +.q \^|\^ ) +the rest of the address is processed as a shell command. +If the user name begins with a slash mark (\c +.q /\^ ) +the name is used as a file name, +instead of a login name. +.pp +Files that have setuid or setgid bits set +but no execute bits set +have those bits honored if +.i sendmail +is running as root. +.sh 2 "Aliasing, Forwarding, Inclusion" +.pp +.i Sendmail +reroutes mail three ways. +Aliasing applies system wide. +Forwarding allows each user to reroute incoming mail +destined for that account. +Inclusion directs +.i sendmail +to read a file for a list of addresses, +and is normally used +in conjunction with aliasing. +.sh 3 "Aliasing" +.pp +Aliasing maps names to address lists using a system-wide file. +This file is indexed to speed access. +Only names that parse as local +are allowed as aliases; +this guarantees a unique key +(since there are no nicknames for the local host). +.sh 3 "Forwarding" +.pp +After aliasing, +recipients that are local and valid +are checked for the existence of a +.q .forward +file in their home directory. +If it exists, +the message is +.i not +sent to that user, +but rather to the list of users in that file. +Often +this list will contain only one address, +and the feature will be used for network mail forwarding. +.pp +Forwarding also permits a user to specify a private incoming mailer. +For example, +forwarding to: +.(b +"\^|\|/usr/local/newmail myname" +.)b +will use a different incoming mailer. +.sh 3 "Inclusion" +.pp +Inclusion is specified in RFC 733 [Crocker77a] syntax: +.(b +:Include: pathname +.)b +An address of this form reads the file specified by +.i pathname +and sends to all users listed in that file. +.pp +The intent is +.i not +to support direct use of this feature, +but rather to use this as a subset of aliasing. +For example, +an alias of the form: +.(b +project: :include:/usr/project/userlist +.)b +is a method of letting a project maintain a mailing list +without interaction with the system administration, +even if the alias file is protected. +.pp +It is not necessary to rebuild the index on the alias database +when a :include: list is changed. +.sh 2 "Message Collection" +.pp +Once all recipient addresses are parsed and verified, +the message is collected. +The message comes in two parts: +a message header and a message body, +separated by a blank line. +.pp +The header is formatted as a series of lines +of the form +.(b + field-name: field-value +.)b +Field-value can be split across lines by starting the following +lines with a space or a tab. +Some header fields have special internal meaning, +and have appropriate special processing. +Other headers are simply passed through. +Some header fields may be added automatically, +such as time stamps. +.pp +The body is a series of text lines. +It is completely uninterpreted and untouched, +except that lines beginning with a dot +have the dot doubled +when transmitted over an SMTP channel. +This extra dot is stripped by the receiver. +.sh 2 "Message Delivery" +.pp +The send queue is ordered by receiving host +before transmission +to implement message batching. +Each address is marked as it is sent +so rescanning the list is safe. +An argument list is built as the scan proceeds. +Mail to files is detected during the scan of the send list. +The interface to the mailer +is performed using one of the techniques +described in section 2.2. +.pp +After a connection is established, +.i sendmail +makes the per-mailer changes to the header +and sends the result to the mailer. +If any mail is rejected by the mailer, +a flag is set to invoke the return-to-sender function +after all delivery completes. +.sh 2 "Queued Messages" +.pp +If the mailer returns a +.q "temporary failure" +exit status, +the message is queued. +A control file is used to describe the recipients to be sent to +and various other parameters. +This control file is formatted as a series of lines, +each describing a sender, +a recipient, +the time of submission, +or some other salient parameter of the message. +The header of the message is stored +in the control file, +so that the associated data file in the queue +is just the temporary file that was originally collected. +.sh 2 "Configuration" +.pp +Configuration is controlled primarily by a configuration file +read at startup. +.i Sendmail +should not need to be recomplied except +.np +To change operating systems +(V6, V7/32V, 4BSD). +.np +To remove or insert the DBM +(UNIX database) +library. +.np +To change ARPANET reply codes. +.np +To add headers fields requiring special processing. +.lp +Adding mailers or changing parsing +(i.e., rewriting) +or routing information +does not require recompilation. +.pp +If the mail is being sent by a local user, +and the file +.q .mailcf +exists in the sender's home directory, +that file is read as a configuration file +after the system configuration file. +The primary use of this feature is to add header lines. +.pp +The configuration file encodes macro definitions, +header definitions, +mailer definitions, +rewriting rules, +and options. +.sh 3 Macros +.pp +Macros can be used in three ways. +Certain macros transmit +unstructured textual information +into the mail system, +such as the name +.i sendmail +will use to identify itself in error messages. +Other macros transmit information from +.i sendmail +to the configuration file +for use in creating other fields +(such as argument vectors to mailers); +e.g., the name of the sender, +and the host and user +of the recipient. +Other macros are unused internally, +and can be used as shorthand in the configuration file. +.sh 3 "Header declarations" +.pp +Header declarations inform +.i sendmail +of the format of known header lines. +Knowledge of a few header lines +is built into +.i sendmail , +such as the +.q From: +and +.q Date: +lines. +.pp +Most configured headers +will be automatically inserted +in the outgoing message +if they don't exist in the incoming message. +Certain headers are suppressed by some mailers. +.sh 3 "Mailer declarations" +.pp +Mailer declarations tell +.i sendmail +of the various mailers available to it. +The definition specifies the internal name of the mailer, +the pathname of the program to call, +some flags associated with the mailer, +and an argument vector to be used on the call; +this vector is macro-expanded before use. +.sh 3 "Address rewriting rules" +.pp +The heart of address parsing in +.i sendmail +is a set of rewriting rules. +These are an ordered list of pattern-replacement rules, +(somewhat like a production system, +except that order is critical), +which are applied to each address. +The address is rewritten textually until it is either rewritten +into a special canonical form +(i.e., +a (mailer, host, user) +3-tuple, +such as {arpanet, usc-isif, postel} +representing the address +.q "postel@usc-isif" ), +or it falls off the end. +When a pattern matches, +the rule is reapplied until it fails. +.pp +The configuration file also supports the editing of addresses +into different formats. +For example, +an address of the form: +.(b +ucsfcgl!tef +.)b +might be mapped into: +.(b +tef@ucsfcgl.UUCP +.)b +to conform to the domain syntax. +Translations can also be done in the other direction. +.sh 3 "Option setting" +.pp +There are several options that can be set +from the configuration file. +These include the pathnames of various support files, +timeouts, +default modes, +etc. +.sh 1 "COMPARISON WITH OTHER MAILERS" +.sh 2 "Delivermail" +.pp +.i Sendmail +is an outgrowth of +.i delivermail . +The primary differences are: +.np +Configuration information is not compiled in. +This change simplifies many of the problems +of moving to other machines. +It also allows easy debugging of new mailers. +.np +Address parsing is more flexible. +For example, +.i delivermail +only supported one gateway to any network, +whereas +.i sendmail +can be sensitive to host names +and reroute to different gateways. +.np +Forwarding and +:include: +features eliminate the requirement that the system alias file +be writable by any user +(or that an update program be written, +or that the system administration make all changes). +.np +.i Sendmail +supports message batching across networks +when a message is being sent to multiple recipients. +.np +A mail queue is provided in +.i sendmail. +Mail that cannot be delivered immediately +but can potentially be delivered later +is stored in this queue for a later retry. +The queue also provides a buffer against system crashes; +after the message has been collected +it may be reliably redelivered +even if the system crashes during the initial delivery. +.np +.i Sendmail +uses the networking support provided by 4.2BSD +to provide a direct interface networks such as the ARPANET +and/or Ethernet +using SMTP (the Simple Mail Transfer Protocol) +over a TCP/IP connection. +.sh 2 "MMDF" +.pp +MMDF +[Crocker79] +spans a wider problem set than +.i sendmail . +For example, +the domain of +MMDF includes a +.q "phone network" +mailer, whereas +.i sendmail +calls on preexisting mailers in most cases. +.pp +MMDF and +.i sendmail +both support aliasing, +customized mailers, +message batching, +automatic forwarding to gateways, +queueing, +and retransmission. +MMDF supports two-stage timeout, +which +.i sendmail +does not support. +.pp +The configuration for MMDF +is compiled into the code\**. +.(f +\**Dynamic configuration tables are currently being considered +for MMDF; +allowing the installer to select either compiled +or dynamic tables. +.)f +.pp +Since MMDF does not consider backwards compatibility +as a design goal, +the address parsing is simpler but much less flexible. +.pp +It is somewhat harder to integrate a new channel\** +.(f +\**The MMDF equivalent of a +.i sendmail +.q mailer. +.)f +into MMDF. +In particular, +MMDF must know the location and format +of host tables for all channels, +and the channel must speak a special protocol. +This allows MMDF to do additional verification +(such as verifying host names) +at submission time. +.pp +MMDF strictly separates the submission and delivery phases. +Although +.i sendmail +has the concept of each of these stages, +they are integrated into one program, +whereas in MMDF they are split into two programs. +.sh 2 "Message Processing Module" +.pp +The Message Processing Module (MPM) +discussed by Postel [Postel79b] +matches +.i sendmail +closely in terms of its basic architecture. +However, +like MMDF, +the MPM includes the network interface software +as part of its domain. +.pp +MPM also postulates a duplex channel to the receiver, +as does MMDF, +thus allowing simpler handling of errors +by the mailer +than is possible in +.i sendmail . +When a message queued by +.i sendmail +is sent, +any errors must be returned to the sender +by the mailer itself. +Both MPM and MMDF mailers +can return an immediate error response, +and a single error processor can create an appropriate response. +.pp +MPM prefers passing the message as a structured object, +with type-length-value tuples\**. +.(f +\**This is similar to the NBS standard. +.)f +Such a convention requires a much higher degree of cooperation +between mailers than is required by +.i sendmail . +MPM also assumes a universally agreed upon internet name space +(with each address in the form of a net-host-user tuple), +which +.i sendmail +does not. +.sh 1 "EVALUATIONS AND FUTURE PLANS" +.pp +.i Sendmail +is designed to work in a nonhomogeneous environment. +Every attempt is made to avoid imposing unnecessary constraints +on the underlying mailers. +This goal has driven much of the design. +One of the major problems +has been the lack of a uniform address space, +as postulated in [Postel79a] +and [Postel79b]. +.pp +A nonuniform address space implies that a path will be specified +in all addresses, +either explicitly (as part of the address) +or implicitly +(as with implied forwarding to gateways). +This restriction has the unpleasant effect of making replying to messages +exceedingly difficult, +since there is no one +.q address +for any person, +but only a way to get there from wherever you are. +.pp +Interfacing to mail programs +that were not initially intended to be applied +in an internet environment +has been amazingly successful, +and has reduced the job to a manageable task. +.pp +.i Sendmail +has knowledge of a few difficult environments +built in. +It generates ARPANET FTP/SMTP compatible error messages +(prepended with three-digit numbers +[Neigus73, Postel74, Postel82]) +as necessary, +optionally generates UNIX-style +.q From +lines on the front of messages for some mailers, +and knows how to parse the same lines on input. +Also, +error handling has an option customized for BerkNet. +.pp +The decision to avoid doing any type of delivery where possible +(even, or perhaps especially, local delivery) +has turned out to be a good idea. +Even with local delivery, +there are issues of the location of the mailbox, +the format of the mailbox, +the locking protocol used, +etc., +that are best decided by other programs. +One surprisingly major annoyance in many internet mailers +is that the location and format of local mail is built in. +The feeling seems to be that local mail is so common +that it should be efficient. +This feeling is not born out by +our experience; +on the contrary, +the location and format of mailboxes seems to vary widely +from system to system. +.pp +The ability to automatically generate a response to incoming mail +(by forwarding mail to a program) +seems useful +(\c +.q "I am on vacation until late August...." ) +but can create problems +such as forwarding loops +(two people on vacation whose programs send notes back and forth, +for instance) +if these programs are not well written. +A program could be written to do standard tasks correctly, +but this would solve the general case. +.pp +It might be desirable to implement some form of load limiting. +I am unaware of any mail system that addresses this problem, +nor am I aware of any reasonable solution at this time. +.pp +The configuration file is currently practically inscrutable; +considerable convenience could be realized +with a higher-level format. +.pp +It seems clear that common protocols will be changing soon +to accommodate changing requirements and environments. +These changes will include modifications to the message header +(e.g., [NBS80]) +or to the body of the message itself +(such as for multimedia messages +[Postel80]). +Experience indicates that +these changes should be relatively trivial to integrate +into the existing system. +.pp +In tightly coupled environments, +it would be nice to have a name server +such as Grapvine +[Birrell82] +integrated into the mail system. +This would allow a site such as +.q Berkeley +to appear as a single host, +rather than as a collection of hosts, +and would allow people to move transparently among machines +without having to change their addresses. +Such a facility +would require an automatically updated database +and some method of resolving conflicts. +Ideally this would be effective even without +all hosts being under +a single management. +However, +it is not clear whether this feature +should be integrated into the +aliasing facility +or should be considered a +.q "value added" +feature outside +.i sendmail +itself. +.pp +As a more interesting case, +the CSNET name server +[Solomon81] +provides an facility that goes beyond a single +tightly-coupled environment. +Such a facility would normally exist outside of +.i sendmail +however. +.sh 0 "ACKNOWLEDGEMENTS" +.pp +Thanks are due to Kurt Shoens for his continual cheerful +assistance and good advice, +Bill Joy for pointing me in the correct direction +(over and over), +and Mark Horton for more advice, +prodding, +and many of the good ideas. +Kurt and Eric Schmidt are to be credited +for using +.i delivermail +as a server for their programs +(\c +.i Mail +and BerkNet respectively) +before any sane person should have, +and making the necessary modifications +promptly and happily. +Eric gave me considerable advice about the perils +of network software which saved me an unknown +amount of work and grief. +Mark did the original implementation of the DBM version +of aliasing, installed the VFORK code, +wrote the current version of +.i rmail , +and was the person who really convinced me +to put the work into +.i delivermail +to turn it into +.i sendmail . +Kurt deserves accolades for using +.i sendmail +when I was myself afraid to take the risk; +how a person can continue to be so enthusiastic +in the face of so much bitter reality is beyond me. +.pp +Kurt, +Mark, +Kirk McKusick, +Marvin Solomon, +and many others have reviewed this paper, +giving considerable useful advice. +.pp +Special thanks are reserved for Mike Stonebraker at Berkeley +and Bob Epstein at Britton-Lee, +who both knowingly allowed me to put so much work into this +project +when there were so many other things I really should +have been working on. +.+c +.ce +REFERENCES +.nr ii 1.5i +.ip [Birrell82] +Birrell, A.

+replace it with a blank sheet for double-sided output. +.bp 7 +.sh 1 "BASIC INSTALLATION" +.pp +There are two basic steps to installing +.i sendmail . +First, you have to compile and install the binary. +If +.i sendmail +has already been ported to your operating system +that should be simple. +Second, you must build a run-time configuration file. +This is a file that +.i sendmail +reads when it starts up +that describes the mailers it knows about, +how to parse addresses, +how to rewrite the message header, +and the settings of various options. +Although the configuration file can be quite complex, +a configuration can usually be built +using an M4-based configuration language. +.pp +The remainder of this section will describe the installation of +.i sendmail +assuming you can use one of the existing configurations +and that the standard installation parameters are acceptable. +All pathnames and examples +are given from the root of the +.i sendmail +subtree, +normally +.i /usr/src/usr.\*(SD/sendmail +on 4.4BSD. +.pp +If you are loading this off the tape, +continue with the next section. +If you have a running binary already on your system, +you should probably skip to section 1.2. +.sh 2 "Compiling Sendmail" +.pp +All +.i sendmail +source is in the +.i src +subdirectory. +To compile sendmail, +.q cd +into the +.i src +directory and type +.(b +\&./Build +.)b +This will leave the binary in an appropriately named subdirectory, +e.g., +obj.BSD-OS.2.1.i386. +It works for multiple object versions +compiled out of the same directory. +.sh 3 "Tweaking the Build Invocation" +.pp +You can give parameters on the +.i Build +command. +In most cases these are only used when the +.i obj.* +directory is first created. +These commands include: +.nr ii 0.5i +.ip "\-L \fIlibdirs\fP" +A list of directories to search for libraries. +.ip "\-I \fIincdirs\fP" +A list of directories to search for include files. +.ip "\-E \fIenvar\fP=\fIvalue\fP" +Set an environment variable to an indicated +.i value +before compiling. +This is normally used to set an ABI on Irix. +.ip "\-c" +Create a new +.i obj.* +tree before running. +.ip "\-f \fIsiteconfig\fP" +Read the indicated site configuration file. +If this parameter is not specified, +.i Build +includes +.i all +of the files +.i $BUILDTOOLS/Site/site.$oscf.m4 +and +.i $BUILDTOOLS/Site/site.config.m4 , +where $BUILDTOOLS is normally +.i \&../BuildTools +and $oscf is the same name as used on the +.i obj.* +directory. +See below for a description of the site configuration file. +.ip "\-S" +Skip auto-configuration. +.i Build +will avoid auto-detecting libraries if this is set. +All libraries and map definitions must be specified +in the site configuration file. +.lp +Any other parameters are passed to the +.i make +program. +.sh 3 "Creating a Site Configuration File" +.\"XXX +.pp +(This section is not yet complete. +For now, see the file BuildTools/README for details.) +.sh 3 "Tweaking the Makefile" +.pp +.b "XXX This should all be in the Site Configuration File section." +.i Sendmail +supports two different formats +for the local (on disk) version of databases, +notably the +.i aliases +database. +At least one of these should be defined if at all possible. +.nr ii 1i +.ip NDBM +The ``new DBM'' format, +available on nearly all systems around today. +This was the preferred format prior to 4.4BSD. +It allows such complex things as multiple databases +and closing a currently open database. +.ip NEWDB +The Berkeley DB package. +If you have this, use it. +It allows +long records, +multiple open databases, +real in-memory caching, +and so forth. +You can define this in conjunction with +.sm NDBM ; +if you do, +old alias databases are read, +but when a new database is created it will be in NEWDB format. +As a nasty hack, +if you have NEWDB, NDBM, and NIS defined, +and if the alias file name includes the substring +.q /yp/ , +.i sendmail +will create both new and old versions of the alias file +during a +.i newalias +command. +This is required because the Sun NIS/YP system +reads the DBM version of the alias file. +It's ugly as sin, +but it works. +.lp +If neither of these are defined, +.i sendmail +reads the alias file into memory on every invocation. +This can be slow and should be avoided. +There are also several methods for remote database access: +.ip NIS +Sun's Network Information Services (formerly YP). +.ip NISPLUS +Sun's NIS+ services. +.ip NETINFO +NeXT's NetInfo service. +.ip HESIOD +Hesiod service (from Athena). +.lp +Other compilation flags are set in conf.h +and should be predefined for you +unless you are porting to a new environment. +.sh 3 "Compilation and installation" +.pp +After making the local system configuration described above, +You should be able to compile and install the system. +The script +.q Build +is the best approach on most systems: +.(b +\&./Build +.)b +This will use +.i uname (1) +to create a custom Makefile for your environment. +.pp +If you are installing in the standard places, +you should be able to install using +.(b +\&./Build install +.)b +This should install the binary in +/usr/\*(SD +and create links from +/usr/\*(SB/newaliases +and +/usr/\*(SB/mailq +to +/usr/\*(SD/sendmail. +On 4.4BSD systems it will also format and install man pages. +.sh 2 "Configuration Files" +.pp +.i Sendmail +cannot operate without a configuration file. +The configuration defines the mail delivery mechanisms understood at this site, +how to access them, +how to forward email to remote mail systems, +and a number of tuning parameters. +This configuration file is detailed +in the later portion of this document. +.pp +The +.i sendmail +configuration can be daunting at first. +The world is complex, +and the mail configuration reflects that. +The distribution includes an m4-based configuration package +that hides a lot of the complexity. +.pp +These configuration files are simpler than old versions +largely because the world has become simpler; +in particular, +text-based host files are officially eliminated, +obviating the need to +.q hide +hosts behind a registered internet gateway. +.pp +These files also assume that most of your neighbors +use domain-based UUCP addressing; +that is, +instead of naming hosts as +.q host!user +they will use +.q host.domain!user . +The configuration files can be customized to work around this, +but it is more complex. +.pp +Our configuration files are processed by +.i m4 +to facilitate local customization; +the directory +.i cf +of the +.i sendmail +distribution directory +contains the source files. +This directory contains several subdirectories: +.nr ii 1i +.ip cf +Both site-dependent and site-independent descriptions of hosts. +These can be literal host names +(e.g., +.q ucbvax.mc ) +when the hosts are gateways +or more general descriptions +(such as +.q "generic-solaris2.mc" +as a general description of an SMTP-connected host +running Solaris 2.x. +Files ending +.b \&.mc +(``Master Configuration'') +are the input descriptions; +the output is in the corresponding +.b \&.cf +file. +The general structure of these files is described below. +.ip domain +Site-dependent subdomain descriptions. +These are tied to the way your organization wants to do addressing. +For example, +.b domain/CS.Berkeley.EDU.m4 +is our description for hosts in the CS.Berkeley.EDU subdomain. +These are referenced using the +.sm DOMAIN +.b m4 +macro in the +.b \&.mc +file. +.ip feature +Definitions of specific features that some particular host in your site +might want. +These are referenced using the +.sm FEATURE +.b m4 +macro. +An example feature is +use_cw_file +(which tells +.i sendmail +to read an /etc/sendmail.cw file on startup +to find the set of local names). +.ip hack +Local hacks, referenced using the +.sm HACK +.b m4 +macro. +Try to avoid these. +The point of having them here is to make it clear that they smell. +.ip m4 +Site-independent +.i m4 (1) +include files that have information common to all configuration files. +This can be thought of as a +.q #include +directory. +.ip mailer +Definitions of mailers, +referenced using the +.sm MAILER +.b m4 +macro. +The mailer types that are known in this distribution are +fax, +local, +smtp, +uucp, +and usenet. +For example, to include support for the UUCP-based mailers, +use +.q MAILER(uucp) . +.ip ostype +Definitions describing various operating system environments +(such as the location of support files). +These are referenced using the +.sm OSTYPE +.b m4 +macro. +.ip sh +Shell files used by the +.b m4 +build process. +You shouldn't have to mess with these. +.ip siteconfig +Local UUCP connectivity information. +This directory has been supplanted by the mailertable feature; +any new configurations should use that feature to do UUCP +(and other) routing. +.pp +If you are in a new domain +(e.g., a company), +you will probably want to create a +cf/domain +file for your domain. +This consists primarily of relay definitions +and features you want enabled site-wide: +for example, Berkeley's domain definition +defines relays for +BitNET +and UUCP. +These are specific to Berkeley, +and should be fully-qualified internet-style domain names. +Please check to make certain they are reasonable for your domain. +.pp +Subdomains at Berkeley are also represented in the +cf/domain +directory. +For example, +the domain +CS.Berkeley.EDU +is the Computer Science subdomain, +EECS.Berkeley.EDU +is the Electrical Engineering and Computer Sciences subdomain, +and +S2K.Berkeley.EDU +is the Sequoia 2000 subdomain. +You will probably have to add an entry to this directory +to be appropriate for your domain. +.pp +You will have to use or create +.b \&.mc +files in the +.i cf/cf +subdirectory for your hosts. +This is detailed in the +cf/README +file. +.sh 2 "Details of Installation Files" +.pp +This subsection describes the files that +comprise the +.i sendmail +installation. +.sh 3 "/usr/\*(SD/sendmail" +.pp +The binary for +.i sendmail +is located in /usr/\*(SD\**. +.(f +\**This is usually +/usr/sbin +on 4.4BSD and newer systems; +many systems install it in +/usr/lib. +I understand it is in /usr/ucblib +on System V Release 4. +.)f +It should be setuid root. +For security reasons, +/, /usr, and /usr/\*(SD +should be owned by root, mode 755\**. +.(f +\**Some vendors ship them owned by bin; +this creates a security hole that is not actually related to +.i sendmail . +Other important directories that should have restrictive ownerships +and permissions are +/bin, /usr/bin, /etc, /usr/etc, /lib, and /usr/lib. +.)f +.sh 3 "/etc/sendmail.cf" +.pp +This is the configuration file for +.i sendmail \**. +.(f +\**Actually, the pathname varies depending on the operating system; +/etc is the preferred directory. +Some older systems install it in +.b /usr/lib/sendmail.cf , +and I've also seen it in +.b /usr/ucblib +and +.b /etc/mail . +If you want to move this file, +add -D_PATH_SENDMAILCF=\e"/file/name\e" +to the flags passed to the C compiler. +Moving this file is not recommended: +other programs and scripts know of this location. +.)f +This is the only non-library file name compiled into +.i sendmail \**. +.(f +\**The system libraries can reference other files; +in particular, system library subroutines that +.i sendmail +calls probably reference +.i /etc/passwd +and +.i /etc/resolv.conf . +.)f +.pp +The configuration file is normally created +using the distribution files described above. +If you have a particularly unusual system configuration +you may need to create a special version. +The format of this file is detailed in later sections +of this document. +.sh 3 "/usr/\*(SB/newaliases" +.pp +The +.i newaliases +command should just be a link to +.i sendmail : +.(b +rm \-f /usr/\*(SB/newaliases +ln \-s /usr/\*(SD/sendmail /usr/\*(SB/newaliases +.)b +This can be installed in whatever search path you prefer +for your system. +.sh 3 "/usr/\*(SB/hoststat" +.pp +The +.i hoststat +command should just be a link to +.i sendmail , +in a fashion similar to +.i newaliases . +This command lists the status of the last mail transaction +with all remote hosts. The +.b \-v +flag will prevent the status display from being truncated. +It functions only when the +.b HostStatusDirectory +option is set. +.sh 3 "/usr/\*(SB/purgestat" +.pp +This command is also a link to +.i sendmail . +It flushes all information that is stored in the +.b HostStatusDirectory +tree. +.sh 3 "/var/spool/mqueue" +.pp +The directory +.i /var/spool/mqueue +should be created to hold the mail queue. +This directory should be mode 700 +and owned by root. +.pp +The actual path of this directory +is defined in the +.b Q +option of the +.i sendmail.cf +file. +.sh 3 "/var/spool/mqueue/.hoststat" +.pp +This is a typical value for the +.b HostStatusDirectory +option, +containing one file per host +that this sendmail has chatted with recently. +It is normally a subdirectory of +.i mqueue . +.sh 3 "/etc/aliases*" +.pp +The system aliases are held in +.q /etc/aliases . +A sample is given in +.q lib/aliases +which includes some aliases which +.i must +be defined: +.(b +cp lib/aliases /etc/aliases +.i "edit /etc/aliases" +.)b +You should extend this file with any aliases that are apropos to your system. +.pp +Normally +.i sendmail +looks at a database version of the files, +stored either in +.q /etc/aliases.dir +and +.q /etc/aliases.pag +or +.q /etc/aliases.db +depending on which database package you are using. +The actual path of this file +is defined in the +.b AliasFile +option of the +.i sendmail.cf +file. +.sh 3 "/etc/rc or /etc/init.d/sendmail" +.pp +It will be necessary to start up the +.i sendmail +daemon when your system reboots. +This daemon performs two functions: +it listens on the SMTP socket for connections +(to receive mail from a remote system) +and it processes the queue periodically +to insure that mail gets delivered when hosts come up. +.pp +Add the following lines to +.q /etc/rc +(or +.q /etc/rc.local +as appropriate) +in the area where it is starting up the daemons +on a BSD-base system, +or on a System-V-based system +in one of the startup files, typically +.q /etc/init.d/sendmail : +.(b +if [ \-f /usr/\*(SD/sendmail \-a \-f /etc/sendmail.cf ]; then + (cd /var/spool/mqueue; rm \-f [lnx]f*) + /usr/\*(SD/sendmail \-bd \-q30m & + echo \-n ' sendmail' >/dev/console +fi +.)b +The +.q cd +and +.q rm +commands insure that all lock files have been removed; +extraneous lock files may be left around +if the system goes down in the middle of processing a message. +The line that actually invokes +.i sendmail +has two flags: +.q \-bd +causes it to listen on the SMTP port, +and +.q \-q30m +causes it to run the queue every half hour. +.pp +Some people use a more complex startup script, +removing zero length qf files and df files for which there is no qf file. +For example, see Figure 1 +for an example of a complex script which does this clean up. +.(z +.hl +#!/bin/sh +# remove zero length qf files +for qffile in qf* +do + if [ \-r $qffile ] + then + if [ ! \-s $qffile ] + then + echo \-n " " > /dev/console + rm \-f $qffile + fi + fi +done +# rename tf files to be qf if the qf does not exist +for tffile in tf* +do + qffile=`echo $tffile | sed 's/t/q/'` + if [ \-r $tffile \-a ! \-f $qffile ] + then + echo \-n " " > /dev/console + mv $tffile $qffile + else + if [ \-f $tffile ] + then + echo \-n " " > /dev/console + rm \-f $tffile + fi + fi +done +# remove df files with no corresponding qf files +for dffile in df* +do + qffile=`echo $dffile | sed 's/d/q/'` + if [ \-r $dffile \-a ! \-f $qffile ] + then + echo \-n " " > /dev/console + mv $dffile `echo $dffile | sed 's/d/D/'` + fi +done +# announce files that have been saved during disaster recovery +for xffile in [A-Z]f* +do + if [ \-f $xffile ] + then + echo \-n " " > /dev/console + fi +done +.sp +.ce +Figure 1 \(em A complex startup script +.hl +.)z +.pp +If you are not running a version of UNIX +that supports Berkeley TCP/IP, +do not include the +.b \-bd +flag. +.sh 3 "/usr/lib/sendmail.hf" +.pp +This is the help file used by the SMTP +.b HELP +command. +It should be copied from +.q lib/sendmail.hf : +.(b +cp lib/sendmail.hf /usr/lib +.)b +The actual path of this file +is defined in the +.b HelpFile +option of the +.i sendmail.cf +file. +.sh 3 "/etc/sendmail.st" +.pp +If you wish to collect statistics +about your mail traffic, +you should create the file +.q /etc/sendmail.st : +.(b +cp /dev/null /etc/sendmail.st +chmod 666 /etc/sendmail.st +.)b +This file does not grow. +It is printed with the program +.q mailstats/mailstats.c. +The actual path of this file +is defined in the +.b S +option of the +.i sendmail.cf +file. +.sh 3 "/usr/\*(SB/mailq" +.pp +If +.i sendmail +is invoked as +.q mailq, +it will simulate the +.b \-bp +flag +(i.e., +.i sendmail +will print the contents of the mail queue;

+there will be exactly one of these per message. +Some fields may be omitted if they do not contain interesting information. +Fields are: +.ip from +The envelope sender address. +.ip size +The size of the message in bytes. +.ip class +The class (i.e., numeric precedence) of the message. +.ip pri +The initial message priority (used for queue sorting). +.ip nrcpts +The number of envelope recipients for this message +(after aliasing and forwarding). +.ip msgid +The message id of the message (from the header). +.ip proto +The protocol used to receive this message (e.g., ESMTP or UUCP) +.ip relay +The machine from which it was received. +.lp +There is also one line logged per delivery attempt +(so there can be several per message if delivery is deferred +or there are multiple recipients). +Fields are: +.ip to +A comma-separated list of the recipients to this mailer. +.ip ctladdr +The ``controlling user'', that is, the name of the user +whose credentials we use for delivery. +.ip delay +The total delay between the time this message was received +and the time it was delivered. +.ip xdelay +The amount of time needed in this delivery attempt +(normally indicative of the speed of the connection). +.ip mailer +The name of the mailer used to deliver to this recipient. +.ip relay +The name of the host that actually accepted (or rejected) this recipient. +.ip stat +The delivery status. +.lp +Not all fields are present in all messages; +for example, the relay is not listed for local deliveries. +.sh 3 "Levels" +.pp +If you have +.i syslogd \|(8) +or an equivalent installed, +you will be able to do logging. +There is a large amount of information that can be logged. +The log is arranged as a succession of levels. +At the lowest level +only extremely strange situations are logged. +At the highest level, +even the most mundane and uninteresting events +are recorded for posterity. +As a convention, +log levels under ten +are considered generally +.q useful; +log levels above 64 +are reserved for debugging purposes. +Levels from 11\-64 are reserved for verbose information +that some sites might want. +.pp +A complete description of the log levels +is given in section +.\" XREF +4.6. +.sh 2 "Dumping State" +.pp +You can ask +.i sendmail +to log a dump of the open files +and the connection cache +by sending it a +.sm SIGUSR1 +signal. +The results are logged at +.sm LOG_DEBUG +priority. +.sh 2 "The Mail Queue" +.pp +Sometimes a host cannot handle a message immediately. +For example, it may be down or overloaded, causing it to refuse connections. +The sending host is then expected to save this message in +its mail queue +and attempt to deliver it later. +.pp +Under normal conditions the mail queue will be processed transparently. +However, you may find that manual intervention is sometimes necessary. +For example, +if a major host is down for a period of time +the queue may become clogged. +Although +.i sendmail +ought to recover gracefully when the host comes up, +you may find performance unacceptably bad in the meantime. +.sh 3 "Printing the queue" +.pp +The contents of the queue can be printed +using the +.i mailq +command +(or by specifying the +.b \-bp +flag to +.i sendmail ): +.(b +mailq +.)b +This will produce a listing of the queue id's, +the size of the message, +the date the message entered the queue, +and the sender and recipients. +.sh 3 "Forcing the queue" +.pp +.i Sendmail +should run the queue automatically +at intervals. +The algorithm is to read and sort the queue, +and then to attempt to process all jobs in order. +When it attempts to run the job, +.i sendmail +first checks to see if the job is locked. +If so, it ignores the job. +.pp +There is no attempt to insure that only one queue processor +exists at any time, +since there is no guarantee that a job cannot take forever +to process +(however, +.i sendmail +does include heuristics to try to abort jobs +that are taking absurd amounts of time; +technically, this violates RFC 821, but is blessed by RFC 1123). +Due to the locking algorithm, +it is impossible for one job to freeze the entire queue. +However, +an uncooperative recipient host +or a program recipient +that never returns +can accumulate many processes in your system. +Unfortunately, +there is no completely general way to solve this. +.pp +In some cases, +you may find that a major host going down +for a couple of days +may create a prohibitively large queue. +This will result in +.i sendmail +spending an inordinate amount of time +sorting the queue. +This situation can be fixed by moving the queue to a temporary place +and creating a new queue. +The old queue can be run later when the offending host returns to service. +.pp +To do this, +it is acceptable to move the entire queue directory: +.(b +cd /var/spool +mv mqueue omqueue; mkdir mqueue; chmod 700 mqueue +.)b +You should then kill the existing daemon +(since it will still be processing in the old queue directory) +and create a new daemon. +.pp +To run the old mail queue, +run the following command: +.(b +/usr/\*(SD/sendmail \-oQ/var/spool/omqueue \-q +.)b +The +.b \-oQ +flag specifies an alternate queue directory +and the +.b \-q +flag says to just run every job in the queue. +If you have a tendency toward voyeurism, +you can use the +.b \-v +flag to watch what is going on. +.pp +When the queue is finally emptied, +you can remove the directory: +.(b +rmdir /var/spool/omqueue +.)b +.sh 2 "Disk Based Connection Information" +.pp +.i Sendmail +stores a large amount of information about each remote system it +has connected to in memory. It is now possible to preserve some +of this information on disk as well, by using the +.b HostStatusDirectory +option, so that it may be shared between several invocations of +.i sendmail . +This allows mail to be queued immediately or skipped during a queue run if +there has been a recent failure in connecting to a remote machine. +.pp +Additionally enabling +.b SingleThreadDelivery +has the added effect of single-threading mail delivery to a destination. +This can be quite helpful +if the remote machine is running an SMTP server that is easily overloaded +or cannot accept more than a single connection at a time, +but can cause some messages to be punted to a future queue run. +It also applies to +.i all +hosts, so setting this because you have one machine on site +that runs some software that is easily overrun +can cause mail to other hosts to be slowed down. +If this option is set, +you probably want to set the +.b MinQueueAge +option as well and run the queue fairly frequently; +this way jobs that are skipped because another +.i sendmail +is talking to the same host will be tried again quickly +rather than being delayed for a long time. +.pp +The disk based host information is stored in a subdirectory of the +.b mqueue +directory called +.b \&.hoststat \**. +.(f +\**This is the usual value of the +.b HostStatusDirectory +option; +it can, of course, go anywhere you like in your filesystem. +.)f +Removing this directory and its subdirectories has an effect similar to +the +.i purgestat +command and is completely safe. +The information in these directories can +be perused with the +.i hoststat +command, which will indicate the host name, the last access, and the +status of that access. +An asterisk in the left most column indicates that a +.i sendmail +process currently has the host locked for mail delivery. +.pp +The disk based connection information is treated the same way as memory based +connection information for the purpose of timeouts. +By default, information about host failures is valid for 30 minutes. +This can be adjusted with +the +.b Timeout.hoststatus +option. +.pp +The connection information stored on disk may be purged at any time +with the +.i purgestat +command or by invoking sendmail with the +.b \-bH +switch. +The connection information may be viewed with the +.i hoststat +command or by invoking sendmail with the +.b \-bh +switch. +.sh 2 "The Service Switch" +.pp +The implementation of certain system services +such as host and user name lookup +is controlled by the service switch. +If the host operating system supports such a switch +.i sendmail +will use the native version. +Ultrix, Solaris, and DEC OSF/1 are examples of such systems\**. +.(f +\**HP-UX 10 has service switch support, +but since the APIs are apparently not available in the libraries +.i sendmail +does not use the native service switch in this release. +.)f +.pp +If the underlying operating system does not support a service switch +(e.g., SunOS, HP-UX, BSD) +then +.i sendmail +will provide a stub implementation. +The +.b ServiceSwitchFile +option points to the name of a file that has the service definitions. +Each line has the name of a service +and the possible implementations of that service. +For example, the file: +.(b +hosts dns files nis +aliases files nis +.)b +will ask +.i sendmail +to look for hosts in the Domain Name System first. +If the requested host name is not found, +it tries local files, +and if that fails it tries NIS. +Similarly, +when looking for aliases +it will try the local files first +followed by NIS. +.pp +Service switches are not completely integrated. +For example, despite the fact that the host entry listed in the above example +specifies to look in NIS, +on SunOS this won't happen because the system implementation of +.i gethostbyname \|(3) +doesn't understand this. +If there is enough demand +.i sendmail +may reimplement +.i gethostbyname \|(3), +.i gethostbyaddr \|(3), +.i getpwent \|(3), +and the other system routines that would be necessary +to make this work seamlessly. +.sh 2 "The Alias Database" +.pp +After recipient addresses are read from the SMTP connection +or command line +they are parsed by ruleset 0, +which must resolve to a +{\c +.i mailer , +.i host , +.i user } +triple. +If the flags selected by the +.i mailer +include the +.b A +(aliasable) flag, +the +.i user +part of the triple is looked up as the key +(i.e., the left hand side) +into the alias database. +If there is a match, the address is deleted from the send queue +and all addresses on the right hand side of the alias +are added in place of the alias that was found. +This is a recursive operation, +so aliases found in the right hand side of the alias +are similarly expanded. +.pp +The alias database exists in two forms. +One is a text form, +maintained in the file +.i /etc/aliases. +The aliases are of the form +.(b +name: name1, name2, ... +.)b +Only local names may be aliased; +e.g., +.(b +eric@prep.ai.MIT.EDU: eric@CS.Berkeley.EDU +.)b +will not have the desired effect +(except on prep.ai.MIT.EDU, +and they probably don't want me)\**. +.(f +\**Actually, any mailer that has the `A' mailer flag set +will permit aliasing; +this is normally limited to the local mailer. +.)f +Aliases may be continued by starting any continuation lines +with a space or a tab. +Blank lines and lines beginning with a sharp sign +(\c +.q # ) +are comments. +.pp +The second form is processed by the +.i ndbm \|(3)\** +.(f +\**The +.i gdbm +package does not work. +.)f +or the Berkeley DB library. +This form is in the file +.i /etc/aliases.db +(if using NEWDB) +or +.i /etc/aliases.dir +and +.i /etc/aliases.pag +(if using NDBM). +This is the form that +.i sendmail +actually uses to resolve aliases. +This technique is used to improve performance. +.pp +The control of search order is actually set by the service switch. +Essentially, the entry +.(b +O AliasFile=switch:aliases +.)b +is always added as the first alias entry; +also, the first alias file name without a class +(e.g., without +.q nis: +on the front) +will be used as the name of the file for a ``files'' entry +in the aliases switch. +For example, if the configuration file contains +.(b +O AliasFile=/etc/aliases +.)b +and the service switch contains +.(b +aliases nis files nisplus +.)b +then aliases will first be searched in the NIS database, +then in /etc/aliases, +then in the NIS+ database. +.pp +You can also use +.sm NIS -based +alias files. +For example, the specification: +.(b +O AliasFile=/etc/aliases +O AliasFile=nis:mail.aliases@my.nis.domain +.)b +will first search the /etc/aliases file +and then the map named +.q mail.aliases +in +.q my.nis.domain . +Warning: if you build your own +.sm NIS -based +alias files, +be sure to provide the +.b \-l +flag to +.i makedbm (8) +to map upper case letters in the keys to lower case; +otherwise, aliases with upper case letters in their names +won't match incoming addresses. +.pp +Additional flags can be added after the colon +exactly like a +.b K +line \(em for example: +.(b +O AliasFile=nis:\-N mail.aliases@my.nis.domain +.)b +will search the appropriate NIS map and always include null bytes in the key. +Also: +.(b +O AliasFile=nis:\-f mail.aliases@my.nis.domain +.)b +will prevent sendmail from downcasing the key before the alias lookup. +.sh 3 "Rebuilding the alias database" +.pp +The +.i hash +or +.i dbm +version of the database +may be rebuilt explicitly by executing the command +.(b +newaliases +.)b +This is equivalent to giving +.i sendmail +the +.b \-bi +flag: +.(b +/usr/\*(SD/sendmail \-bi +.)b +.pp +If the +.b RebuildAliases +(old +.b D ) +option is specified in the configuration, +.i sendmail +will rebuild the alias database automatically +if possible +when it is out of date. +Auto-rebuild can be dangerous +on heavily loaded machines +with large alias files; +if it might take more than the rebuild timeout +(option +.b AliasWait , +old +.b a , +which is normally five minutes) +to rebuild the database, +there is a chance that several processes will start the rebuild process +simultaneously. +.pp +If you have multiple aliases databases specified, +the +.b \-bi +flag rebuilds all the database types it understands +(for example, it can rebuild NDBM databases but not NIS databases). +.sh 3 "Potential problems" +.pp +There are a number of problems that can occur +with the alias database. +They all result from a +.i sendmail +process accessing the DBM version +while it is only partially built. +This can happen under two circumstances: +One process accesses the database +while another process is rebuilding it, +or the process rebuilding the database dies +(due to being killed or a system crash) +before completing the rebuild. +.pp +Sendmail has three techniques to try to relieve these problems. +First, it ignores interrupts while rebuilding the database; +this avoids the problem of someone aborting the process +leaving a partially rebuilt database. +Second, +it locks the database source file during the rebuild \(em +but that may not work over NFS or if the file is unwritable. +Third, +at the end of the rebuild +it adds an alias of the form +.(b +@: @ +.)b +(which is not normally legal). +Before +.i sendmail +will access the database, +it checks to insure that this entry exists\**. +.(f +\**The +.b AliasWait +option is required in the configuration +for this action to occur. +This should normally be specified. +.)f +.sh 3 "List owners" +.pp +If an error occurs on sending to a certain address, +say +.q \fIx\fP , +.i sendmail +will look for an alias +of the form +.q owner-\fIx\fP +to receive the errors. +This is typically useful +for a mailing list +where the submitter of the list +has no control over the maintenance of the list itself; +in this case the list maintainer would be the owner of the list. +For example: +.(b +unix-wizards: eric@ucbarpa, wnj@monet, nosuchuser, + sam@matisse +owner-unix-wizards: unix-wizards-request +unix-wizards-request: eric@ucbarpa +.)b +would cause +.q eric@ucbarpa +to get the error that will occur +when someone sends to +unix-wizards +due to the inclusion of +.q nosuchuser +on the list. +.pp +List owners also cause the envelope sender address to be modified. +The contents of the owner alias are used if they point to a single user, +otherwise the name of the alias itself is used. +For this reason, and to obey Internet conventions, +the +.q owner- +address normally points at the +.q -request +address; this causes messages to go out with the typical Internet convention +of using ``\c +.i list -request'' +as the return address. +.sh 2 "User Information Database" +.pp +If you have a version of +.i sendmail +with the user information database +compiled in, +and you have specified one or more databases using the +.b U +option, +the databases will be searched for a +.i user :maildrop +entry. +If found, the mail will be sent to the specified address. +.sh 2 "Per-User Forwarding (.forward Files)" +.pp +As an alternative to the alias database, +any user may put a file with the name +.q .forward +in his or her home directory. +If this file exists, +.i sendmail +redirects mail for that user +to the list of addresses listed in the .forward file. +For example, if the home directory for user +.q mckusick +has a .forward file with contents: +.(b +mckusick@ernie +kirk@calder +.)b +then any mail arriving for +.q mckusick +will be redirected to the specified accounts. +.pp +Actually, the configuration file defines a sequence of filenames to check. +By default, this is the user's .forward file, +but can be defined to be more generally using the +.b ForwardPath +option. +If you change this, +you will have to inform your user base of the change; +\&.forward is pretty well incorporated into the collective subconscious. +.sh 2 "Special Header Lines" +.pp +Several header lines have special interpretations +defined by the configuration file. +Others have interpretations built into +.i sendmail +that cannot be changed without changing the code. +These builtins are described here. +.sh 3 "Errors-To:" +.pp +If errors occur anywhere during processing, +this header will cause error messages to go to +the listed addresses. +This is intended for mailing lists. +.pp +The Errors-To: header was created in the bad old days +when UUCP didn't understand the distinction between an envelope and a header; +this was a hack to provide what should now be passed +as the envelope sender address. +It should go away. +It is only used if the +.b UseErrorsTo +option is set. +.pp +The Errors-To: header is officially deprecated +and will go away in a future release. +.sh 3 "Apparently-To:" +.pp +RFC 822 requires at least one recipient field +(To:, Cc:, or Bcc: line) +in every message. +If a message comes in with no recipients listed in the message +then +.i sendmail +will adjust the header based on the +.q NoRecipientAction +option. +One of the possible actions is to add an +.q "Apparently-To:" +header line for any recipients it is aware of. +.pp +The Apparently-To: header is non-standard +and is deprecated. +.sh 3 "Precedence" +.pp +The Precedence: header can be used as a crude control of message priority. +It tweaks the sort order in the queue +and can be configured to change the message timeout values. +.sh 2 "IDENT Protocol Support" +.pp +.i Sendmail +supports the IDENT protocol as defined in RFC 1413. +Although this enhances identification +of the author of an email message +by doing a ``call back'' to the originating system to include +the owner of a particular TCP connection +in the audit trail +it is in no sense perfect; +a determined forger can easily spoof the IDENT protocol. +The following description is excerpted from RFC 1413: +.ba +5 +.lp +6. Security Considerations +.lp +The information returned by this protocol is at most as trustworthy +as the host providing it OR the organization operating the host. For +example, a PC in an open lab has few if any controls on it to prevent +a user from having this protocol return any identifier the user +wants. Likewise, if the host has been compromised the information +returned may be completely erroneous and misleading. +.lp +The Identification Protocol is not intended as an authorization or +access control protocol. At best, it provides some additional +auditing information with respect to TCP connections. At worst, it +can provide misleading, incorrect, or maliciously incorrect +information. +.lp +The use of the information returned by this protocol for other than +auditing is strongly discouraged. Specifically, using Identification +Protocol information to make access control decisions - either as the +primary method (i.e., no other checks) or as an adjunct to other +methods may result in a weakening of normal host security. +.lp +An Identification server may reveal information about users, +entities, objects or processes which might normally be considered +private. An Identification server provides service which is a rough +analog of the CallerID services provided by some phone companies and +many of the same privacy considerations and arguments that apply to +the CallerID service apply to Identification. If you wouldn't run a +"finger" server due to privacy considerations you may not want to run +this protocol. +.ba +.lp +In some cases your system may not work properly with IDENT support +due to a bug in the TCP/IP implementation. +The symptoms will be that for some hosts +the SMTP connection will be closed +almost immediately. +If this is true or if you do not want to use IDENT, +you should set the IDENT timeout to zero; +this will disable the IDENT protocol. +.sh 1 "ARGUMENTS" +.pp +The complete list of arguments to +.i sendmail +is described in detail in Appendix A. +Some important arguments are described here. +.sh 2 "Queue Interval" +.pp +The amount of time between forking a process +to run through the queue +is defined by the +.b \-q +flag. +If you run with delivery mode set to +.b i +or +.b b +this can be relatively large, +since it will only be relevant +when a host that was down comes back up. +If you run in +.b q +mode +it should be relatively short, +since it defines the maximum amount of time that a message +may sit in the queue. +(See also the MinQueueAge option.) +.pp +RFC 1123 section 5.3.1.1 says that this value should be at least 30 minutes +(although that probably doesn't make sense if you use ``queue-only'' mode). +.sh 2 "Daemon Mode" +.pp +If you allow incoming mail over an IPC connection, +you should have a daemon running. +This should be set by your +.i /etc/rc +file using the +.b \-bd +flag. +The +.b \-bd +flag and the +.b \-q +flag may be combined in one call: +.(b +/usr/\*(SD/sendmail \-bd \-q30m +.)b +.pp +An alternative approach is to invoke sendmail from +.i inetd (8) +(use the +.b \-bs +flag to ask sendmail to speak SMTP on its standard input and output). +This works and allows you to wrap +.i sendmail +in a TCP wrapper program, +but may be a bit slower since the configuration file +has to be re-read on every message that comes in. +If you do this, you still need to have a +.i sendmail +running to flush the queue: +.(b +/usr/\*(SD/sendmail \-q30m +.)b +.sh 2 "Forcing the Queue" +.pp +In some cases you may find that the queue has gotten clogged for some reason. +You can force a queue run +using the +.b \-q +flag (with no value). +It is entertaining to use the +.b \-v +flag (verbose) +when this is done to watch what happens: +.(b +/usr/\*(SD/sendmail \-q \-v +.)b +.pp +You can also limit the jobs to those with a particular queue identifier, +sender, or recipient +using one of the queue modifiers. +For example, +.q \-qRberkeley +restricts the queue run to jobs that have the string +.q berkeley +somewhere in one of the recipient addresses. +Similarly, +.q \-qSstring +limits the run to particular senders and +.q \-qIstring +limits it to particular queue identifiers. +.sh 2 "Debugging" +.pp +There are a fairly large number of debug flags +built into +.i sendmail . +Each debug flag has a number and a level, +where higher levels means to print out more information. +The convention is that levels greater than nine are +.q absurd, +i.e., +they print out so much information that you wouldn't normally +want to see them except for debugging that particular piece of code. +Debug flags are set using the +.b \-d +option; +the syntax is: +.(b +.ta \w'debug-option 'u +debug-flag: \fB\-d\fP debug-list +debug-list: debug-option [ , debug-option ]* +debug-option: debug-range [ . debug-level ] +debug-range: integer | integer \- integer +debug-level: integer +.)b +where spaces are for reading ease only. +For example, +.(b +\-d12 Set flag 12 to level 1 +\-d12.3 Set flag 12 to level 3 +\-d3\-17 Set flags 3 through 17 to level 1 +\-d3\-17.4 Set flags 3 through 17 to level 4 +.)b +For a complete list of the available debug flags +you will have to look at the code +(they are too dynamic to keep this documentation up to date). +.sh 2 "Changing the Values of Options" +.pp +Options can be overridden using the +.b \-o +or +.b \-O +command line flags. +For example, +.(b +/usr/\*(SD/sendmail \-oT2m +.)b +sets the +.b T +(timeout) option to two minutes +for this run only; +the equivalent line using the long option name is +.(b +/usr/\*(SD/sendmail -OTimeout.queuereturn=2m +.)b +.pp +Some options have security implications. +Sendmail allows you to set these, +but relinquishes its setuid root permissions thereafter\**. +.(f +\**That is, it sets its effective uid to the real uid; +thus, if you are executing as root, +as from root's crontab file or during system startup +the root permissions will still be honored. +.)f +.sh 2 "Trying a Different Configuration File" +.pp +An alternative configuration file +can be specified using the +.b \-C +flag; for example, +.(b +/usr/\*(SD/sendmail \-Ctest.cf \-oQ/tmp/mqueue +.)b +uses the configuration file +.i test.cf +instead of the default +.i /etc/sendmail.cf. +If the +.b \-C +flag has no value +it defaults to +.i sendmail.cf +in the current directory. +.pp +.i Sendmail +gives up its setuid root permissions +when you use this flag, so it is common to use a publicly writable directory +(such as /tmp) +as the spool directory (QueueDirectory or Q option) while testing. +.sh 2 "Logging Traffic" +.pp +Many SMTP implementations do not fully implement the protocol. +For example, some personal computer based SMTPs +do not understand continuation lines in reply codes. +These can be very hard to trace. +If you suspect such a problem, you can set traffic logging using the +.b \-X +flag. +For example, +.(b +/usr/\*(SD/sendmail \-X /tmp/traffic \-bd +.)b +will log all traffic in the file +.i /tmp/traffic . +.pp +This logs a lot of data very quickly and should +.b NEVER +be used +during normal operations. +After starting up such a daemon, +force the errant implementation to send a message to your host. +All message traffic in and out of +.i sendmail , +including the incoming SMTP traffic, +will be logged in this file. +.sh 2 "Testing Configuration Files" +.pp +When you build a configuration table, +you can do a certain amount of testing +using the +.q "test mode" +of +.i sendmail . +For example, +you could invoke +.i sendmail +as: +.(b +sendmail \-bt \-Ctest.cf +.)b +which would read the configuration file +.q test.cf +and enter test mode. +In this mode, +you enter lines of the form: +.(b +rwset address +.)b +where +.i rwset +is the rewriting set you want to use +and +.i address +is an address to apply the set to. +Test mode shows you the steps it takes +as it proceeds, +finally showing you the address it ends up with. +You may use a comma separated list of rwsets +for sequential application of rules to an input. +For example: +.(b +3,1,21,4 monet:bollard +.)b +first applies ruleset three to the input +.q monet:bollard. +Ruleset one is then applied to the output of ruleset three, +followed similarly by rulesets twenty-one and four. +.pp +If you need more detail, +you can also use the +.q \-d21 +flag to turn on more debugging. +For example, +.(b +sendmail \-bt \-d21.99 +.)b +turns on an incredible amount of information; +a single word address +is probably going to print out several pages worth of information. +.pp +You should be warned that internally, +.i sendmail +applies ruleset 3 to all addresses. +In test mode +you will have to do that manually. +For example, older versions allowed you to use +.(b +0 bruce@broadcast.sony.com +.)b +This version requires that you use: +.(b +3,0 bruce@broadcast.sony.com +.)b +.pp +As of version 8.7, +some other syntaxes are available in test mode: +.bu +\&.D\|x\|value +defines macro +.i x +to have the indicated +.i value . +This is useful when debugging rules that use the +.b $& \c +.i x +syntax. +.bu +\&.C\|c\|value +adds the indicated +.i value +to class +.i c . +.bu +\&.S\|ruleset +dumps the contents of the indicated ruleset. +.bu +\-d\|debug-spec +is equivalent to the command-line flag. +.sh 2 "Persistent Host Status Information" +.pp +When +.b HostStatusDirectory +is enabled, +information about the status of hosts is maintained on disk +and can thus be shared between different instantiations of +.i sendmail . +The status of the last connection with each remote host +may be viewed with the command: +.(b +sendmail \-bh +.)b +This information may be flushed with the command: +.(b +sendmail \-bH +.)b +Flushing the information prevents new +.i sendmail +processes from loading it, +but does not prevent existing processes from using the status information +that they already have. +.sh 1 "TUNING" +.pp +There are a number of configuration parameters +you may want to change, +depending on the requirements of your site. +Most of these are set +using an option in the configuration file. +For example, +the line +.q "O Timeout.queuereturn=5d" +sets option +.q Timeout.queuereturn +to the value +.q 5d +(five days). +.pp +Most of these options have appropriate defaults for most sites. +However, +sites having very high mail loads may find they need to tune them +as appropriate for their mail load. +In particular, +sites experiencing a large number of small messages, +many of which are delivered to many recipients, +may find that they need to adjust the parameters +dealing with queue priorities. +.pp +All versions of +.i sendmail +prior to 8.7 +had single character option names. +As of 8.7, +options have long (multi-character names). +Although old short names are still accepted, +most new options do not have short equivalents. +.pp +This section only describes the options you are most likely +to want to tweak; +read section +.\"XREF +5 +for more details. +.sh 2 "Timeouts" +.pp +All time intervals are set +using a scaled syntax. +For example, +.q 10m +represents ten minutes, whereas +.q 2h30m +represents two and a half hours. +The full set of scales is: +.(b +.ta 4n +s seconds +m minutes +h hours +d days +w weeks +.)b +.sh 3 "Queue interval" +.pp +The argument to the +.b \-q +flag +specifies how often a sub-daemon will run the queue. +This is typically set to between fifteen minutes +and one hour. +RFC 1123 section 5.3.1.1 recommends that this be at least 30 minutes. +.sh 3 "Read timeouts" +.pp +Timeouts all have option names +.q Timeout.\fIsuboption\fP . +The recognized +.i suboption s, +their default values, and the minimum values +allowed by RFC 1123 section 5.3.2 are: +.nr ii 1i +.ip connect +The time to wait for an SMTP connection to open +(the +.i connect (2) +system call) +[0, unspecified]. +If zero, uses the kernel default. +In no case can this option extend the timeout +longer than the kernel provides, but it can shorten it. +This is to get around kernels that provide an absurdly long connection timeout +(90 minutes in one case). +.ip iconnect +The same as +.i connect, +except it applies only to the initial attempt to connect to a host +for a given message +[0, unspecified]. +The concept is that this should be very short (a few seconds); +hosts that are well connected and responsive will thus be serviced immediately. +Hosts that are slow will not hold up other deliveries in the initial +delivery attempt. +.ip initial +The wait for the initial 220 greeting message +[5m, 5m]. +.ip helo +The wait for a reply from a HELO or EHLO command +[5m, unspecified]. +This may require a host name lookup, so +five minutes is probably a reasonable minimum. +.ip mail\(dg +The wait for a reply from a MAIL command +[10m, 5m]. +.ip rcpt\(dg +The wait for a reply from a RCPT command +[1h, 5m]. +This should be long +because it could be pointing at a list +that takes a long time to expand +(see below). +.ip datainit\(dg +The wait for a reply from a DATA command +[5m, 2m]. +.ip datablock\(dg +The wait for reading a data block +(that is, the body of the message). +[1h, 3m]. +This should be long because it also applies to programs +piping input to +.i sendmail +which have no guarantee of promptness. +.ip datafinal\(dg +The wait for a reply from the dot terminating a message. +[1h, 10m]. +If this is shorter than the time actually needed +for the receiver to deliver the message, +duplicates will be generated. +This is discussed in RFC 1047. +.ip rset +The wait for a reply from a RSET command +[5m, unspecified]. +.ip quit +The wait for a reply from a QUIT command +[2m, unspecified]. +.ip misc +The wait for a reply from miscellaneous (but short) commands +such as NOOP (no-operation) and VERB (go into verbose mode). +[2m, unspecified]. +.ip command\(dg +In server SMTP, +the time to wait for another command. +[1h, 5m]. +.ip ident +The timeout waiting for a reply to an IDENT query +[30s\**, unspecified]. +.(f +\**On some systems the default is zero to turn the protocol off entirely. +.)f +.ip hoststatus +How long status information about a host +(e.g., host down) +will be cached before it is considered stale +[30m, unspecified]. +.lp +For compatibility with old configuration files, +if no +.i suboption +is specified, +all the timeouts marked with \(dg are set to the indicated value. +.pp +Many of the RFC 1123 minimum values +may well be too short. +.i Sendmail +was designed to the RFC 822 protocols, +which did not specify read timeouts; +hence, versions of +.i sendmail +prior to version 8.1 did not guarantee to reply to messages promptly. +In particular, a +.q RCPT +command specifying a mailing list +will expand and verify the entire list; +a large list on a slow system +may easily take more than five minutes\**. +.(f +\**This verification includes looking up every address +with the name server; +this involves network delays, +and can in some cases can be considerable. +.)f +I recommend a one hour timeout \*- +since a communications failure during the RCPT phase is rare, +a long timeout is not onerous +and may ultimately help reduce network load +and duplicated messages. +.pp +For example, the lines: +.(b +O Timeout.command=25m +O Timeout.datablock=3h +.)b +sets the server SMTP command timeout to 25 minutes +and the input data block timeout to three hours. +.sh 3 "Message timeouts" +.pp +After sitting in the queue for a few days, +a message will time out. +This is to insure that at least the sender is aware +of the inability to send a message. +The timeout is typically set to five days. +It is sometimes considered convenient to also send a warning message +if the message is in the queue longer than a few hours +(assuming you normally have good connectivity; +if your messages normally took several hours to send +you wouldn't want to do this because it wouldn't be an unusual event). +These timeouts are set using the +.b Timeout.queuereturn +and +.b Timeout.queuewarn +options in the configuration file +(previously both were set using the +.b T +option). +.pp +Since these options are global, +and since you can not know +.i "a priori" +how long another host outside your domain will be down, +a five day timeout is recommended. +This allows a recipient to fix the problem even if it occurs +at the beginning of a long weekend. +RFC 1123 section 5.3.1.1 says that this parameter +should be ``at least 4\-5 days''. +.pp +The +.b Timeout.queuewarn +value can be piggybacked on the +.b T +option by indicating a time after which +a warning message should be sent; +the two timeouts are separated by a slash. +For example, the line +.(b +OT5d/4h +.)b +causes email to fail after five days, +but a warning message will be sent after four hours. +This should be large enough that the message will have been tried +several times. +.sh 2 "Forking During Queue Runs" +.pp +By setting the +.b ForkEachJob +(\c +.b Y ) +option, +.i sendmail +will fork before each individual message +while running the queue. +This will prevent +.i sendmail +from consuming large amounts of memory, +so it may be useful in memory-poor environments. +However, if the +.b ForkEachJob +option is not set, +.i sendmail +will keep track of hosts that are down during a queue run, +which can improve performance dramatically. +.pp +If the +.b ForkEachJob +option is set, +.i sendmail +can not use connection caching. +.sh 2 "Queue Priorities" +.pp +Every message is assigned a priority when it is first instantiated, +consisting of the message size (in bytes) +offset by the message class +(which is determined from the Precedence: header) +times the +.q "work class factor" +and the number of recipients times the +.q "work recipient factor." +The priority is used to order the queue. +Higher numbers for the priority mean that the message will be processed later +when running the queue. +.pp +The message size is included so that large messages are penalized +relative to small messages. +The message class allows users to send +.q "high priority" +messages by including a +.q Precedence: +field in their message; +the value of this field is looked up in the +.b P +lines of the configuration file. +Since the number of recipients affects the amount of load a message presents +to the system, +this is also included into the priority. +.pp +The recipient and class factors +can be set in the configuration file using the +.b RecipientFactor +(\c +.b y ) +and +.b ClassFactor +(\c +.b z ) +options respectively. +They default to 30000 (for the recipient factor) +and 1800 +(for the class factor). +The initial priority is: +.EQ +pri = msgsize - (class times bold ClassFactor) + (nrcpt times bold RecipientFactor) +.EN +(Remember, higher values for this parameter actually mean +that the job will be treated with lower priority.) +.pp +The priority of a job can also be adjusted each time it is processed +(that is, each time an attempt is made to deliver it) +using the +.q "work time factor," +set by the +.b RetryFactor +(\c +.b Z ) +option. +This is added to the priority, +so it normally decreases the precedence of the job, +on the grounds that jobs that have failed many times +will tend to fail again in the future. +The +.b RetryFactor +option defaults to 90000. +.sh 2 "Load Limiting" +.pp +.i Sendmail +can be asked to queue (but not deliver) +mail if the system load average gets too high +using the +.b QueueLA +(\c +.b x ) +option. +When the load average exceeds the value of the +.b QueueLA +option, +the delivery mode is set to +.b q +(queue only) +if the +.b QueueFactor +(\c +.b q ) +option divided by the difference in the current load average and the +.b QueueLA +option +plus one +exceeds the priority of the message \(em +that is, the message is queued iff: +.EQ +pri > { bold QueueFactor } over { LA - { bold QueueLA } + 1 } +.EN +The +.b QueueFactor +option defaults to 600000, +so each point of load average is worth 600000 +priority points +(as described above). +.pp +For drastic cases, +the +.b RefuseLA +(\c +.b X ) +option defines a load average at which +.i sendmail +will refuse +to accept network connections. +Locally generated mail +(including incoming UUCP mail) +is still accepted. +.sh 2 "Delivery Mode" +.pp +There are a number of delivery modes that +.i sendmail +can operate in, +set by the +.b DeliveryMode +(\c +.b d ) +configuration option. +These modes +specify how quickly mail will be delivered. +Legal modes are: +.(b +.ta 4n +i deliver interactively (synchronously) +b deliver in background (asynchronously) +q queue only (don't deliver) +d defer delvery attempts (don't deliver) +.)b +There are tradeoffs. +Mode +.q i +gives the sender the quickest feedback, +but may slow down some mailers and +is hardly ever necessary. +Mode +.q b +delivers promptly but +can cause large numbers of processes +if you have a mailer that takes a long time to deliver a message. +Mode +.q q +minimizes the load on your machine, +but means that delivery may be delayed for up to the queue interval. +Mode +.q d +is identical to mode +.q q +except that it also prevents all the early map lookups from working; +it is intended for ``dial on demand'' sites where DNS lookups +might cost real money. +Some simple error messages +(e.g., host unknown during the SMTP protocol) +will be delayed using this mode. +Mode +.q b +is the usual default. +.pp +If you run in mode +.q q +(queue only), +.q d +(defer), +or +.q b +(deliver in background) +.i sendmail +will not expand aliases and follow .forward files +upon initial receipt of the mail. +This speeds up the response to RCPT commands. +Mode +.q i +cannot be used by the SMTP server. +.sh 2 "Log Level" +.pp +The level of logging can be set for +.i sendmail . +The default using a standard configuration table is level 9. +The levels are as follows: +.nr ii 0.5i +.ip 0 +Minimal logging. +.ip 1 +Serious system failures and potential security problems. +.ip 2 +Lost communications (network problems) and protocol failures. +.ip 3 +Other serious failures, malformed addresses, transient forward/include +errors, connection timeouts. +.ip 4 +Minor failures, out of date alias databases, connection rejections +via check_ rulesets. +.ip 5 +Message collection statistics. +.ip 6 +Creation of error messages, +VRFY and EXPN commands. +.ip 7 +Delivery failures (host or user unknown, etc.). +.ip 8 +Successful deliveries and alias database rebuilds. +.ip 9 +Messages being deferred +(due to a host being down, etc.). +.ip 10 +Database expansion (alias, forward, and userdb lookups). +.ip 11 +NIS errors and end of job processing. +.ip 12 +Logs all SMTP connections. +.ip 13 +Log bad user shells, files with improper permissions, and other +questionable situations. +.ip 14 +Logs refused connections. +.ip 15 +Log all incoming and outgoing SMTP commands. +.ip 20 +Logs attempts to run locked queue files. +These are not errors, +but can be useful to note if your queue appears to be clogged. +.ip 30 +Lost locks (only if using lockf instead of flock). +.lp +Additionally, +values above 64 are reserved for extremely verbose debugging output. +No normal site would ever set these. +.sh 2 "File Modes" +.pp +The modes used for files depend on what functionality you want +and the level of security you require. +In many cases +.i sendmail +does careful checking of the modes +of files and directories +to avoid accidental compromise; +if you want to make it possible to have group-writable support files +you may need to use the +.b DontBlameSendmail +option to turn off some of these checks. +.sh 3 "To suid or not to suid?" +.pp +.i Sendmail +is normally installed +setuid to root. +At the point where it is about to +.i exec \|(2) +a mailer, +it checks to see if the userid is zero (root); +if so, +it resets the userid and groupid to a default +(set by the +.b U= +equate in the mailer line; +if that is not set, the +.b DefaultUser +option is used). +This can be overridden +by setting the +.b S +flag to the mailer +for mailers that are trusted +and must be called as root. +However, +this will cause mail processing +to be accounted +(using +.i sa \|(8)) +to root +rather than to the user sending the mail. +.pp +If you don't make +.i sendmail +setuid to root, it will still run but you lose a lot of functionality +and a lot of privacy, since you'll have to make the queue directory +world readable. +You could also make +.i sendmail +setuid to some pseudo-user +(e.g., create a user called +.q sendmail +and make +.i sendmail +setuid to that) +which will fix the privacy problems +but not the functionality issues. +Also, this isn't a guarantee of security: +for example, +root occasionally sends mail, +and the daemon often runs as root. +Note however that +.i sendmail +must run as root in order to create the SMTP listener socket. +.pp +A middle ground is to make +.i sendmail +setuid to root, +but set the +.b RunAsUser +option. +This causes +.i sendmail +to become the indicated user as soon as it has done the startup +that requires root privileges +(primarily, opening the +.sm SMTP +socket). +If you use +.b RunAsUser , +the queue directory +(normally +.i /var/spool/mqueue ) +should be owned by that user, +and all files and databases +(including user +.i \&.forward +files, +alias files, +:include: files, +and external databases) +must be readable by that user. +.b RunAsUser +is probably best suited for firewall configurations +that don't have regular user logins. +.sh 3 "Turning off security checks" +.pp +.i Sendmail +is very particular about the modes of files that it reads or writes. +For example, by default it will refuse to read most files +that are group writable +on the grounds that they might have been tampered with +by someone other than the owner; +it will even refuse to read files in group writable directories. +.pp +If you are +.i quite +sure that your configuration is safe and you want +.i sendmail +to avoid these security checks, +you can turn off certain checks using the +.b DontBlameSendmail +option. +This option takes one or more names that disable checks. +In the descriptions that follow, +.q "unsafe directory" +means a directory that is writable by anyone other than the owner. +The values are: +.nr ii 0.5i +.ip Safe +No special handling. +.ip AssumeSafeChown +Assume that the +.i chown +system call is restricted to root. +Since some versions of Unix permit regular users +to give away their files to other users on some filesystems, +.i sendmail +often cannot assume that a given file was created by the owner, +particularly when it is in a writable directory. +You can set this flag if you know that file giveaway is restricted +on your system. +.ip ClassFileInUnsafeDirPath +When reading class files (using the +.b F +line in the configuration file), +allow files that are in unsafe directories. +.ip ErrorHeaderInUnsafeDirPath +Allow the file named in the +.b ErrorHeader +option to be in an unsafe directory. +.ip GroupWritableDirPathSafe +Change the definition of +.q "unsafe directory" +to consider group-writable directories to be safe. +World-writable directories are always unsafe. +.ip GroupWritableForwardFileSafe +Accept group-writable +.i \&.forward +files. +.ip GroupWritableIncludeFileSafe +Accept group-writable +.i :include: +files. +.ip GroupWritableAliasFile +Allow group-writable alias files. +.ip HelpFileInUnsafeDirPath +Allow the file named in the +.b HelpFile +option to be in an unsafe directory. +.ip WorldWritableAliasFile +Accept world-writable alias files. +.ip ForwardFileInGroupWritableDirPath +Allow +.i \&.forward +files in group writable directories. +.ip IncludeFileInGroupWritableDirPath +Allow +.i :include: +files in group writable directories. +.ip ForwardFileInUnsafeDirPath +Allow +.i \&.forward +files in unsafe directories. +.ip IncludeFileInUnsafeDirPath +Allow +.i :include: +files in unsafe directories. +.ip ForwardFileInUnsafeDirPathSafe +Allow a +.i \&.forward +file that is in an unsafe directory to include references +to program and files. +.ip IncludeFileInUnsafeDirPathSafe +Allow a +.i :include: +file that is in an unsafe directory to include references +to program and files. +.ip MapInUnsafeDirPath +Allow maps (e.g., +.i hash , +.i btree , +and +.i dbm +files) +in unsafe directories. +.ip LinkedAliasFileInWritableDir +Allow an alias file that is a link in a writable directory. +.ip LinkedClassFileInWritableDir +Allow class files that are links in writable directories. +.ip LinkedForwardFileInWritableDir +Allow +.i \&.forward +files that are links in writable directories. +.ip LinkedIncludeFileInWritableDir +Allow +.i :include: +files that are links in writable directories. +.ip LinkedMapInWritableDir +Allow map files that are links in writable directories. +.ip LinkedServiceSwitchFileInWritableDir +Allow the service switch file to be a link +even if the directory is writable. +.ip FileDeliveryToHardLink +Allow delivery to files that are hard links. +.ip FileDeliveryToSymLink +Allow delivery to files that are symbolic links. +.ip RunProgramInUnsafeDirPath +Go ahead and run programs that are in writable directories. +.ip RunWritableProgram +Go ahead and run programs that are group- or world-writable. +.ip WriteMapToHardLink +Allow writes to maps that are hard links. +.ip WriteMapToSymLink +Allow writes to maps that are symbolic links. +.ip WriteStatsToHardLink +Allow the status file to be a hard link. +.ip WriteStatsToSymLink +Allow the status file to be a symbolic link. +.sh 2 "Connection Caching" +.pp +When processing the queue, +.i sendmail +will try to keep the last few open connections open +to avoid startup and shutdown costs. +This only applies to IPC connections. +.pp +When trying to open a connection +the cache is first searched. +If an open connection is found, it is probed to see if it is still active +by sending a +.sm RSET +command. +It is not an error if this fails; +instead, the connection is closed and reopened. +.pp +Two parameters control the connection cache. +The +.b ConnectionCacheSize +(\c +.b k ) +option defines the number of simultaneous open connections +that will be permitted. +If it is set to zero, +connections will be closed as quickly as possible. +The default is one. +This should be set as appropriate for your system size; +it will limit the amount of system resources that +.i sendmail +will use during queue runs. +Never set this higher than 4. +.pp +The +.b ConnectionCacheTimeout +(\c +.b K ) +option specifies the maximum time that any cached connection +will be permitted to idle. +When the idle time exceeds this value +the connection is closed. +This number should be small +(under ten minutes) +to prevent you from grabbing too many resources +from other hosts. +The default is five minutes. +.sh 2 "Name Server Access" +.pp +Control of host address lookups is set by the +.b hosts +service entry in your service switch file. +If you are on a system that has built-in service switch support +(e.g., Ultrix, Solaris, or DEC OSF/1) +then your system is probably configured properly already. +Otherwise, +.i sendmail +will consult the file +.b /etc/service.switch , +which should be created. +.i Sendmail +only uses two entries: +.b hosts +and +.b aliases , +although system routines may use other services +(notably the +.b passwd +service for user name lookups by +.i getpwname ). +.pp +However, some systems (such as SunOS) +will do DNS lookups +regardless of the setting of the service switch entry. +In particular, the system routine +.i gethostbyname (3) +is used to look up host names, +and many vendor versions try some combination of DNS, NIS, +and file lookup in /etc/hosts +without consulting a service switch. +.i Sendmail +makes no attempt to work around this problem, +and the DNS lookup will be done anyway. +If you do not have a nameserver configured at all, +such as at a UUCP-only site, +.i sendmail +will get a +.q "connection refused" +message when it tries to connect to the name server. +If the +.b hosts +switch entry has the service +.q dns +listed somewhere in the list, +.i sendmail +will interpret this to mean a temporary failure +and will queue the mail for later processing; +otherwise, it ignores the name server data. +.pp +The same technique is used to decide whether to do MX lookups. +If you want MX support, you +.i must +have +.q dns +listed as a service in the +.b hosts +switch entry. +.pp +The +.b ResolverOptions +(\c +.b I ) +option allows you to tweak name server options. +The command line takes a series of flags as documented in +.i resolver (3) +(with the leading +.q RES_ +deleted). +Each can be preceded by an optional `+' or `\(mi'. +For example, the line +.(b +O ResolverOptions=+AAONLY \(miDNSRCH +.)b +turns on the AAONLY (accept authoritative answers only) +and turns off the DNSRCH (search the domain path) options. +Most resolver libraries default DNSRCH, DEFNAMES, and RECURSE +flags on and all others off. +You can also include +.q HasWildcardMX +to specify that there is a wildcard MX record matching your domain; +this turns off MX matching when canonifying names, +which can lead to inappropriate canonifications. +.pp +Version level 1 configurations +turn DNSRCH and DEFNAMES off when doing delivery lookups, +but leave them on everywhere else. +Version 8 of +.i sendmail +ignores them when doing canonification lookups +(that is, when using $[ ... $]), +and always does the search. +If you don't want to do automatic name extension, +don't call $[ ... $]. +.pp +The search rules for $[ ... $] are somewhat different than usual. +If the name being looked up +has at least one dot, it always tries the unmodified name first. +If that fails, it tries the reduced search path, +and lastly tries the unmodified name +(but only for names without a dot, +since names with a dot have already been tried). +This allows names such as +``utc.CS'' +to match the site in Czechoslovakia +rather than the site in your local Computer Science department. +It also prefers A and CNAME records over MX records \*- +that is, if it finds an MX record it makes note of it, +but keeps looking. +This way, if you have a wildcard MX record matching your domain, +it will not assume that all names match. +.pp +To completely turn off all name server access +on systems without service switch support +(such as SunOS) +you will have to recompile with +\-DNAMED_BIND=0 +and remove \-lresolv from the list of libraries to be searched +when linking. +.sh 2 "Moving the Per-User Forward Files" +.pp +Some sites mount each user's home directory +from a local disk on their workstation, +so that local access is fast. +However, the result is that .forward file lookups are slow. +In some cases, +mail can even be delivered on machines inappropriately +because of a file server being down. +The performance can be especially bad if you run the automounter. +.pp +The +.b ForwardPath +(\c +.b J ) +option allows you to set a path of forward files. +For example, the config file line +.(b +O ForwardPath=/var/forward/$u:$z/.forward.$w +.)b +would first look for a file with the same name as the user's login +in /var/forward; +if that is not found (or is inaccessible) +the file +``.forward.\c +.i machinename '' +in the user's home directory is searched. +A truly perverse site could also search by sender +by using $r, $s, or $f. +.pp +If you create a directory such as /var/forward, +it should be mode 1777 +(that is, the sticky bit should be set). +Users should create the files mode 644. +Note that you must use the +forwardfileinunsafedirpath and +forwardfileinunsafedirpathsafe +flags with the DontBlameSendmail option +to allow forward files in a world +writable directory. +.sh 2 "Free Space" +.pp +On systems that have one of the system calls in the +.i statfs (2) +family +(including +.i statvfs +and +.i ustat ), +you can specify a minimum number of free blocks on the queue filesystem +using the +.b MinFreeBlocks +(\c +.b b ) +option. +If there are fewer than the indicated number of blocks free +on the filesystem on which the queue is mounted +the SMTP server will reject mail +with the +452 error code. +This invites the SMTP client to try again later. +.pp +Beware of setting this option too high; +it can cause rejection of email +when that mail would be processed without difficulty. +.sh 2 "Maximum Message Size" +.pp +To avoid overflowing your system with a large message, +the +.b MaxMessageSize +option can be set to set an absolute limit +on the size of any one message. +This will be advertised in the ESMTP dialogue +and checked during message collection. +.sh 2 "Privacy Flags" +.pp +The +.b PrivacyOptions +(\c +.b p ) +option allows you to set certain +``privacy'' +flags. +Actually, many of them don't give you any extra privacy, +rather just insisting that client SMTP servers +use the HELO command +before using certain commands +or adding extra headers to indicate possible spoof attempts. +.pp +The option takes a series of flag names; +the final privacy is the inclusive or of those flags. +For example: +.(b +O PrivacyOptions=needmailhelo, noexpn +.)b +insists that the HELO or EHLO command be used before a MAIL command is accepted +and disables the EXPN command. +.pp +The flags are detailed in section +.\"XREF +5.6. +.sh 2 "Send to Me Too" +.pp +Normally, +.i sendmail +deletes the (envelope) sender from any list expansions. +For example, if +.q matt +sends to a list that contains +.q matt +as one of the members he won't get a copy of the message. +If the +.b \-m +(me too) +command line flag, or if the +.b MeToo +(\c +.b m ) +option is set in the configuration file, +this behaviour is suppressed. +Some sites like to run the +.sm SMTP +daemon with +.b \-m . +.sh 1 "THE WHOLE SCOOP ON THE CONFIGURATION FILE" +.pp +This section describes the configuration file +in detail. +.pp +There is one point that should be made clear immediately: +the syntax of the configuration file +is designed to be reasonably easy to parse, +since this is done every time +.i sendmail +starts up, +rather than easy for a human to read or write. +On the +.q "future project" +list is a +configuration-file compiler. +.pp +The configuration file is organized as a series of lines, +each of which begins with a single character +defining the semantics for the rest of the line. +Lines beginning with a space or a tab +are continuation lines +(although the semantics are not well defined in many places). +Blank lines and lines beginning with a sharp symbol +(`#') +are comments. +.sh 2 "R and S \*- Rewriting Rules" +.pp +The core of address parsing +are the rewriting rules. +These are an ordered production system. +.i Sendmail +scans through the set of rewriting rules +looking for a match on the left hand side +(LHS) +of the rule. +When a rule matches, +the address is replaced by the right hand side +(RHS) +of the rule. +.pp +There are several sets of rewriting rules. +Some of the rewriting sets are used internally +and must have specific semantics. +Other rewriting sets +do not have specifically assigned semantics, +and may be referenced by the mailer definitions +or by other rewriting sets. +.pp +The syntax of these two commands are: +.(b F +.b S \c +.i n +.)b +Sets the current ruleset being collected to +.i n . +If you begin a ruleset more than once +it appends to the old definition. +.(b F +.b R \c +.i lhs +.i rhs +.i comments +.)b +The +fields must be separated +by at least one tab character; +there may be embedded spaces +in the fields. +The +.i lhs +is a pattern that is applied to the input. +If it matches, +the input is rewritten to the +.i rhs . +The +.i comments +are ignored. +.pp +Macro expansions of the form +.b $ \c +.i x +are performed when the configuration file is read. +Expansions of the form +.b $& \c +.i x +are performed at run time using a somewhat less general algorithm. +This is intended only for referencing internally defined macros +such as +.b $h +that are changed at runtime. +.sh 3 "The left hand side" +.pp +The left hand side of rewriting rules contains a pattern. +Normal words are simply matched directly. +Metasyntax is introduced using a dollar sign. +The metasymbols are: +.(b +.ta \w'\fB$=\fP\fIx\fP 'u +\fB$*\fP Match zero or more tokens +\fB$+\fP Match one or more tokens +\fB$\-\fP Match exactly one token +\fB$=\fP\fIx\fP Match any phrase in class \fIx\fP +\fB$~\fP\fIx\fP Match any word not in class \fIx\fP +.)b +If any of these match, +they are assigned to the symbol +.b $ \c +.i n +for replacement on the right hand side, +where +.i n +is the index in the LHS. +For example, +if the LHS: +.(b +$\-:$+ +.)b +is applied to the input: +.(b +UCBARPA:eric +.)b +the rule will match, and the values passed to the RHS will be: +.(b +.ta 4n +$1 UCBARPA +$2 eric +.)b +.pp +Additionally, the LHS can include +.b $@ +to match zero tokens. +This is +.i not +bound to a +.b $ \c +.i n +on the RHS, and is normally only used when it stands alone +in order to match the null input. +.sh 3 "The right hand side" +.pp +When the left hand side of a rewriting rule matches, +the input is deleted and replaced by the right hand side. +Tokens are copied directly from the RHS +unless they begin with a dollar sign. +Metasymbols are: +.(b +.ta \w'$#mailer\0\0\0'u +\fB$\fP\fIn\fP Substitute indefinite token \fIn\fP from LHS +\fB$[\fP\fIname\fP\fB$]\fP Canonicalize \fIname\fP +\fB$(\fP\fImap key\fP \fB$@\fP\fIarguments\fP \fB$:\fP\fIdefault\fP \fB$)\fP + Generalized keyed mapping function +\fB$>\fP\fIn\fP \*(lqCall\*(rq ruleset \fIn\fP +\fB$#\fP\fImailer\fP Resolve to \fImailer\fP +\fB$@\fP\fIhost\fP Specify \fIhost\fP +\fB$:\fP\fIuser\fP Specify \fIuser\fP +.)b +.pp +The +.b $ \c +.i n +syntax substitutes the corresponding value from a +.b $+ , +.b $\- , +.b $* , +.b $= , +or +.b $~ +match on the LHS. +It may be used anywhere. +.pp +A host name enclosed between +.b $[ +and +.b $] +is looked up in the host database(s) +and replaced by the canonical name\**. +.(f +\**This is actually +completely equivalent +to $(host \fIhostname\fP$). +In particular, a +.b $: +default can be used. +.)f +For example, +.q $[ftp$] +might become +.q ftp.CS.Berkeley.EDU +and +.q $[[128.32.130.2]$] +would become +.q vangogh.CS.Berkeley.EDU. +.i Sendmail +recognizes its numeric IP address +without calling the name server +and replaces it with its canonical name. +.pp +The +.b $( +\&... +.b $) +syntax is a more general form of lookup; +it uses a named map instead of an implicit map. +If no lookup is found, the indicated +.i default +is inserted; +if no default is specified and no lookup matches, +the value is left unchanged. +The +.i arguments +are passed to the map for possible use. +.pp +The +.b $> \c +.i n +syntax +causes the remainder of the line to be substituted as usual +and then passed as the argument to ruleset +.i n . +The final value of ruleset +.i n +then becomes +the substitution for this rule. +The +.b $> +syntax expands everything after the ruleset name +to the end of the replacement string +and then passes that as the initial input to the ruleset. +Recursive calls are allowed. +For example, +.(b +$>0 $>3 $1 +.)b +expands $1, passes that to ruleset 3, and then passes the result +of ruleset 3 to ruleset 0. +.pp +The +.b $# +syntax should +.i only +be used in ruleset zero +or a subroutine of ruleset zero. +It causes evaluation of the ruleset to terminate immediately, +and signals to +.i sendmail +that the address has completely resolved. +The complete syntax is: +.(b +\fB$#\fP\fImailer\fP \fB$@\fP\fIhost\fP \fB$:\fP\fIuser\fP +.)b +This specifies the +{mailer, host, user} +3-tuple necessary to direct the mailer. +If the mailer is local +the host part may be omitted\**. +.(f +\**You may want to use it for special +.q "per user" +extensions. +For example, in the address +.q jgm+foo@CMU.EDU ;

Without it, the key is discarded or if +.b \-s +if used, it is substituted by the substring matches, delimited by +.b $| +or the string specified with the the +.b \-d +flag. The flags availble for the map are +.(b +-n not +-f case sensitive +-b basic regular expressions + (default is extended) +-s substring match +-d set the delimiter used for -s +-a append string to key +-m match only, do not + replace/discard value +.)b +The +.b \-s flag can include an optional parameter which can be used +to select the substrings in the result of the lookup. For example, +.(b +-s1,3,4 +.)b +.ip program +The arguments on the +.b K +line are the pathname to a program and any initial parameters to be passed. +When the map is called, +the key is added to the initial parameters +and the program is invoked +as the default user/group id. +The first line of standard output is returned as the value of the lookup. +This has many potential security problems, +and has terrible performance; +it should be used only when absolutely necessary. +.pp +Most of these accept as arguments the same optional flags +and a filename +(or a mapname for NIS; +the filename is the root of the database path, +so that +.q .db +or some other extension appropriate for the database type +will be added to get the actual database name). +Known flags are: +.ip "\-o" +Indicates that this map is optional \*- that is, +if it cannot be opened, +no error is produced, +and +.i sendmail +will behave as if the map existed but was empty. +.ip "\-N, \-O" +If neither +.b \-N +or +.b \-O +are specified, +.i sendmail +uses an adaptive algorithm to decide whether or not to look for null bytes +on the end of keys. +It starts by trying both; +if it finds any key with a null byte it never tries again without a null byte +and vice versa. +If +.b \-N +is specified it never tries without a null byte and +if +.b \-O +is specified it never tries with a null byte. +Setting one of +these can speed matches but are never necessary. +If both +.b \-N +and +.b \-O +are specified, +.i sendmail +will never try any matches at all \(em +that is, everything will appear to fail. +.ip "\-a\fIx\fP" +Append the string +.i x +on successful matches. +For example, the default +.i host +map appends a dot on successful matches. +.ip "\-T\fIx\fP" +Append the string +.i x +on temporary failures. +For example, +.i x +would be appended if a DNS lookup returned +.q "server failed" +or an NIS lookup could not locate a server. +See also the +.b \-t +flag. +.ip "\-f" +Do not fold upper to lower case before looking up the key. +.ip "\-m" +Match only (without replacing the value). +If you only care about the existence of a key and not the value +(as you might when searching the NIS map +.q hosts.byname +for example), +this flag prevents the map from substituting the value. +However, +The \-a argument is still appended on a match, +and the default is still taken if the match fails. +.ip "\-k\fIkeycol\fP" +The key column name (for NIS+) or number +(for text lookups). +For LDAP maps this is a filter string +passed to printf with a %s where the string to be +.q "mapped" +is inserted. +.ip "\-v\fIvalcol\fP" +The value column name (for NIS+) or number +(for text lookups). +For LDAP maps this is the name of the +attribute to be returned. +.ip "\-z\fIdelim\fP" +The column delimiter (for text lookups). +It can be a single character or one of the special strings +.q \|\en +or +.q \|\et +to indicate newline or tab respectively. +If omitted entirely, +the column separator is any sequence of whitespace. +.ip "\-t" +Normally, when a map attempts to do a lookup +and the server fails +(e.g., +.i sendmail +couldn't contact any name server; +this is +.i not +the same as an entry not being found in the map), +the message being processed is queued for future processing. +The +.b \-t +flag turns off this behaviour, +letting the temporary failure (server down) +act as though it were a permanent failure (entry not found). +It is particularly useful for DNS lookups, +where someone else's misconfigured name server can cause problems +on your machine. +However, care must be taken to ensure that you don't bounce mail +that would be resolved correctly if you tried again. +A common strategy is to forward such mail +to another, possibly better connected, mail server. +.ip "\-s\fIspacesub\fP +For the dequote map only, +the character to use to replace space characters +after a successful dequote. +.ip "\-q" +Don't dequote the key before lookup. +.ip "\-A" +When rebuilding an alias file, +the +.b \-A +flag causes duplicate entries in the text version +to be merged. +For example, two entries: +.(b +list: user1, user2 +list: user3 +.)b +would be treated as though it were the single entry +.(b +list: user1, user2, user3 +.)b +in the presence of the +.b \-A +flag. +.pp +The +.i dbm +map appends the strings +.q \&.pag +and +.q \&.dir +to the given filename;

+usually +.q _avenrun +or +.q avenrun ). +.sh 2 "Configuration in src/conf.c" +.pp +The following changes can be made in conf.c. +.sh 3 "Built-in Header Semantics" +.pp +Not all header semantics are defined in the configuration file. +Header lines that should only be included by certain mailers +(as well as other more obscure semantics) +must be specified in the +.i HdrInfo +table in +.i conf.c . +This table contains the header name +(which should be in all lower case) +and a set of header control flags (described below), +The flags are: +.ip H_ACHECK +Normally when the check is made to see if a header line is compatible +with a mailer, +.i sendmail +will not delete an existing line. +If this flag is set, +.i sendmail +will delete +even existing header lines. +That is, +if this bit is set and the mailer does not have flag bits set +that intersect with the required mailer flags +in the header definition in +sendmail.cf, +the header line is +.i always +deleted. +.ip H_EOH +If this header field is set, +treat it like a blank line, +i.e., +it will signal the end of the header +and the beginning of the message text. +.ip H_FORCE +Add this header entry +even if one existed in the message before. +If a header entry does not have this bit set, +.i sendmail +will not add another header line if a header line +of this name already existed. +This would normally be used to stamp the message +by everyone who handled it. +.ip H_TRACE +If set, +this is a timestamp +(trace) +field. +If the number of trace fields in a message +exceeds a preset amount +the message is returned +on the assumption that it has an aliasing loop. +.ip H_RCPT +If set, +this field contains recipient addresses. +This is used by the +.b \-t +flag to determine who to send to +when it is collecting recipients from the message. +.ip H_FROM +This flag indicates that this field +specifies a sender. +The order of these fields in the +.i HdrInfo +table specifies +.i sendmail 's +preference +for which field to return error messages to. +.ip H_ERRORSTO +Addresses in this header should receive error messages. +.ip H_CTE +This header is a Content-Transfer-Encoding header. +.ip H_CTYPE +This header is a Content-Type header. +.ip H_STRIPVAL +Strip the value from the header (for Bcc:). +.nr ii 5n +.lp +Let's look at a sample +.i HdrInfo +specification: +.(b +.ta 4n +\w'"content-transfer-encoding", 'u +struct hdrinfo HdrInfo[] = +\&{ + /* originator fields, most to least significant */ + "resent-sender", H_FROM, + "resent-from", H_FROM, + "sender", H_FROM, + "from", H_FROM, + "full-name", H_ACHECK, + "errors-to", H_FROM\^|\^H_ERRORSTO, + /* destination fields */ + "to", H_RCPT, + "resent-to", H_RCPT, + "cc", H_RCPT, + "bcc", H_RCPT\^|\^H_STRIPVAL, + /* message identification and control */ + "message", H_EOH, + "text", H_EOH, + /* trace fields */ + "received", H_TRACE\^|\^H_FORCE, + /* miscellaneous fields */ + "content-transfer-encoding", H_CTE, + "content-type", H_CTYPE, + + NULL, 0, +}; +.)b +This structure indicates that the +.q To: , +.q Resent-To: , +and +.q Cc: +fields +all specify recipient addresses. +Any +.q Full-Name: +field will be deleted unless the required mailer flag +(indicated in the configuration file) +is specified. +The +.q Message: +and +.q Text: +fields will terminate the header; +these are used by random dissenters around the network world. +The +.q Received: +field will always be added, +and can be used to trace messages. +.pp +There are a number of important points here. +First, +header fields are not added automatically just because they are in the +.i HdrInfo +structure; +they must be specified in the configuration file +in order to be added to the message. +Any header fields mentioned in the configuration file but not +mentioned in the +.i HdrInfo +structure have default processing performed; +that is, +they are added unless they were in the message already. +Second, +the +.i HdrInfo +structure only specifies cliched processing; +certain headers are processed specially by ad hoc code +regardless of the status specified in +.i HdrInfo . +For example, +the +.q Sender: +and +.q From: +fields are always scanned on ARPANET mail +to determine the sender\**; +.(f +\**Actually, this is no longer true in SMTP; +this information is contained in the envelope. +The older ARPANET protocols did not completely distinguish +envelope from header. +.)f +this is used to perform the +.q "return to sender" +function. +The +.q "From:" +and +.q "Full-Name:" +fields are used to determine the full name of the sender +if possible; +this is stored in the macro +.b $x +and used in a number of ways. +.sh 3 "Restricting Use of Email" +.pp +If it is necessary to restrict mail through a relay, +the +.i checkcompat +routine can be modified. +This routine is called for every recipient address. +It returns an exit status +indicating the status of the message. +The status +.sm EX_OK +accepts the address, +.sm EX_TEMPFAIL +queues the message for a later try, +and other values +(commonly +.sm EX_UNAVAILABLE ) +reject the message. +It is up to +.i checkcompat +to print an error message +(using +.i usrerr ) +if the message is rejected. +For example, +.i checkcompat +could read: +.(b +.re +.sz -1 +.ta 4n +4n +4n +4n +4n +4n +4n +int +checkcompat(to, e) + register ADDRESS *to; + register ENVELOPE *e; +\&{ + register STAB *s; + + s = stab("private", ST_MAILER, ST_FIND); + if (s != NULL && e\->e_from.q_mailer != LocalMailer && + to->q_mailer == s->s_mailer) + { + usrerr("No private net mail allowed through this machine"); + return (EX_UNAVAILABLE); + } + if (MsgSize > 50000 && bitnset(M_LOCALMAILER, to\->q_mailer)) + { + usrerr("Message too large for non-local delivery"); + e\->e_flags |= EF_NORETURN; + return (EX_UNAVAILABLE); + } + return (EX_OK); +} +.sz +.)b +This would reject messages greater than 50000 bytes +unless they were local. +The +.i EF_NORETURN +flag can be set in +.i e\(->e_flags +to suppress the return of the actual body +of the message in the error return. +The actual use of this routine is highly dependent on the +implementation, +and use should be limited. +.sh 3 "New Database Map Classes" +.pp +New key maps can be added by creating a class initialization function +and a lookup function. +These are then added to the routine +.i setupmaps. +.pp +The initialization function is called as +.(b +\fIxxx\fP_map_init(MAP *map, char *args) +.)b +The +.i map +is an internal data structure. +The +.i args +is a pointer to the portion of the configuration file line +following the map class name; +flags and filenames can be extracted from this line. +The initialization function must return +.sm TRUE +if it successfully opened the map, +.sm FALSE +otherwise. +.pp +The lookup function is called as +.(b +\fIxxx\fP_map_lookup(MAP *map, char buf[], char **av, int *statp) +.)b +The +.i map +defines the map internally. +The +.i buf +has the input key. +This may be (and often is) used destructively. +The +.i av +is a list of arguments passed in from the rewrite line. +The lookup function should return a pointer to the new value. +If the map lookup fails, +.i *statp +should be set to an exit status code; +in particular, it should be set to +.sm EX_TEMPFAIL +if recovery is to be attempted by the higher level code. +.sh 3 "Queueing Function" +.pp +The routine +.i shouldqueue +is called to decide if a message should be queued +or processed immediately. +Typically this compares the message priority to the current load average. +The default definition is: +.(b +bool +shouldqueue(pri, ctime) + long pri; + time_t ctime; +{ + if (CurrentLA < QueueLA) + return (FALSE); + return (pri > (QueueFactor / (CurrentLA \- QueueLA + 1))); +} +.)b +If the current load average +(global variable +.i CurrentLA , +which is set before this function is called) +is less than the low threshold load average +(option +.b x , +variable +.i QueueLA ), +.i shouldqueue +returns +.sm FALSE +immediately +(that is, it should +.i not +queue). +If the current load average exceeds the high threshold load average +(option +.b X , +variable +.i RefuseLA ), +.i shouldqueue +returns +.sm TRUE +immediately. +Otherwise, it computes the function based on the message priority, +the queue factor +(option +.b q , +global variable +.i QueueFactor ), +and the current and threshold load averages. +.pp +An implementation wishing to take the actual age of the message into account +can also use the +.i ctime +parameter, +which is the time that the message was first submitted to +.i sendmail . +Note that the +.i pri +parameter is already weighted +by the number of times the message has been tried +(although this tends to lower the priority of the message with time); +the expectation is that the +.i ctime +would be used as an +.q "escape clause" +to ensure that messages are eventually processed. +.sh 3 "Refusing Incoming SMTP Connections" +.pp +The function +.i refuseconnections +returns +.sm TRUE +if incoming SMTP connections should be refused. +The current implementation is based exclusively on the current load average +and the refuse load average option +(option +.b X , +global variable +.i RefuseLA ): +.(b +bool +refuseconnections() +{ + return (CurrentLA >= RefuseLA); +} +.)b +A more clever implementation +could look at more system resources. +.sh 3 "Load Average Computation" +.pp +The routine +.i getla +returns the current load average (as a rounded integer). +The distribution includes several possible implementations. +If you are porting to a new environment +you may need to add some new tweaks.\** +.(f +\**If you do, please send updates to +sendmail@Sendmail.ORG. +.)f +.sh 2 "Configuration in src/daemon.c" +.pp +The file +.i src/daemon.c +contains a number of routines that are dependent +on the local networking environment. +The version supplied assumes you have BSD style sockets. +.pp +In previous releases, +we recommended that you modify the routine +.i maphostname +if you wanted to generalize +.b $[ +\&...\& +.b $] +lookups. +We now recommend that you create a new keyed map instead. +.sh 1 "ACKNOWLEDGEMENTS" +.pp +I've worked on +.i sendmail +for many years, +and many employers have been remarkably patient +about letting me work on a large project +that was not part of my official job. +This includes time on the INGRES Project at +the University of California at Berkeley, +at Britton Lee, +and again on the Mammoth and Titan Projects at Berkeley. +.pp +Much of the second wave of improvements +resulting in version 8.1 +should be credited to Bryan Costales of the +International Computer Science Institute. +As he passed me drafts of his book on +.i sendmail +I was inspired to start working on things again. +Bryan was also available to bounce ideas off of. +.pp +Gregory Neil Shapiro +of Worchester Polytechnic Institute +has become instrumental in all phases of +.i sendmail +support and development, +and was largely responsible for getting versions 8.8 and 8.9 +out the door. +.pp +Many, many people contributed chunks of code and ideas to +.i sendmail . +It has proven to be a group network effort. +Version 8 in particular was a group project. +The following people made notable contributions: +.(l +John Beck, Hewlett-Packard & Sun Microsystems +Keith Bostic, CSRG, University of California, Berkeley +Andrew Cheng, Sun Microsystems +Michael J.

+in particular, +the mail system can refer to users +using a host-username pair. +Host names and numbers have to be administered by a central authority, +but usernames can be assigned locally to each host. +.pp +In an internet, +multiple networks with different characteristics +and managements +must communicate. +In particular, +the syntax and semantics of resource identification change. +Certain special cases can be handled trivially +by +.i "ad hoc" +techniques, +such as +providing network names that appear local to hosts +on other networks, +as with the Ethernet at Xerox PARC. +However, the general case is extremely complex. +For example, +some networks require that the route the message takes +be explicitly specified by the sender, +simplifying the database update problem +since only adjacent hosts must be entered +into the system tables, +while others use logical addressing, +where the sender specifies the location of the recipient +but not how to get there. +Some networks use a left-associative syntax +and others use a right-associative syntax, +causing ambiguity in mixed addresses. +.pp +Internet standards seek to eliminate these problems. +Initially, these proposed expanding the address pairs +to address triples, +consisting of +{network, host, username} +triples. +Network numbers must be universally agreed upon, +and hosts can be assigned locally +on each network. +The user-level presentation was changed +to address domains, +comprised of a local resource identification +and a hierarchical domain specification +with a common static root. +The domain technique +separates the issue of physical versus logical addressing. +For example, +an address of the form +.q "eric@a.cc.berkeley.arpa" +describes the logical +organization of the address space +(user +.q eric +on host +.q a +in the Computer Center +at Berkeley) +but not the physical networks used +(for example, this could go over different networks +depending on whether +.q a +were on an ethernet +or a store-and-forward network). +.pp +.i Sendmail +is intended to help bridge the gap +between the totally +.i "ad hoc" +world +of networks that know nothing of each other +and the clean, tightly-coupled world +of unique network numbers. +It can accept old arbitrary address syntaxes, +resolving ambiguities using heuristics +specified by the system administrator, +as well as domain-based addressing. +It helps guide the conversion of message formats +between disparate networks. +In short, +.i sendmail +is designed to assist a graceful transition +to consistent internetwork addressing schemes. +.sp +.pp +Section 1 defines some of the terms +frequently left fuzzy +when working in mail systems. +Section 2 discusses the design goals for +.i sendmail . +In section 3, +the new address formats +and basic features of +.i sendmail +are described. +Section 4 discusses some of the special problems +of the UUCP network. +The differences between +.i sendmail +and +.i delivermail +are presented in section 5. +.sp +.(l F +.b DISCLAIMER: +A number of examples +in this paper +use names of actual people +and organizations. +This is not intended +to imply a commitment +or even an intellectual agreement +on the part of these people or organizations. +In particular, +Bell Telephone Laboratories (BTL), +Digital Equipment Corporation (DEC), +Lawrence Berkeley Laboratories (LBL), +Britton-Lee Incorporated (BLI), +and the University of California at Berkeley +are not committed to any of these proposals at this time. +Much of this paper +represents no more than +the personal opinions of the author. +.)l +.sh 1 "DEFINITIONS" +.pp +There are four basic concepts +that must be clearly distinguished +when dealing with mail systems: +the user (or the user's agent), +the user's identification, +the user's address, +and the route. +These are distinguished primarily by their position independence. +.sh 2 "User and Identification" +.pp +The user is the being +(a person or program) +that is creating or receiving a message. +An +.i agent +is an entity operating on behalf of the user \*- +such as a secretary who handles my mail. +or a program that automatically returns a +message such as +.q "I am at the UNICOM conference." +.pp +The identification is the tag +that goes along with the particular user. +This tag is completely independent of location. +For example, +my identification is the string +.q "Eric Allman," +and this identification does not change +whether I am located at U.C. Berkeley, +at Britton-Lee, +or at a scientific institute in Austria. +.pp +Since the identification is frequently ambiguous +(e.g., there are two +.q "Robert Henry" s +at Berkeley) +it is common to add other disambiguating information +that is not strictly part of the identification +(e.g., +Robert +.q "Code Generator" +Henry +versus +Robert +.q "System Administrator" +Henry). +.sh 2 "Address" +.pp +The address specifies a location. +As I move around, +my address changes. +For example, +my address might change from +.q eric@Berkeley.ARPA +to +.q eric@bli.UUCP +or +.q allman@IIASA.Austria +depending on my current affiliation. +.pp +However, +an address is independent of the location of anyone else. +That is, +my address remains the same to everyone who might be sending me mail. +For example, +a person at MIT and a person at USC +could both send to +.q eric@Berkeley.ARPA +and have it arrive to the same mailbox. +.pp +Ideally a +.q "white pages" +service would be provided to map user identifications +into addresses +(for example, see +[Solomon81]). +Currently this is handled by passing around +scraps of paper +or by calling people on the telephone +to find out their address. +.sh 2 "Route" +.pp +While an address specifies +.i where +to find a mailbox, +a route specifies +.i how +to find the mailbox. +Specifically, +it specifies a path +from sender to receiver. +As such, the route is potentially different +for every pair of people in the electronic universe. +.pp +Normally the route is hidden from the user +by the software. +However, +some networks put the burden of determining the route +onto the sender. +Although this simplifies the software, +it also greatly impairs the usability +for most users. +The UUCP network is an example of such a network. +.sh 1 "DESIGN GOALS" +.pp +Design goals for +.i sendmail \** +.(f +\**This section makes no distinction between +.i delivermail +and +.i sendmail. +.)f +include: +.np +Compatibility with the existing mail programs, +including Bell version 6 mail, +Bell version 7 mail, +Berkeley +.i Mail +[Shoens79], +BerkNet mail +[Schmidt79], +and hopefully UUCP mail +[Nowitz78]. +ARPANET mail +[Crocker82] +was also required. +.np +Reliability, in the sense of guaranteeing +that every message is correctly delivered +or at least brought to the attention of a human +for correct disposal; +no message should ever be completely lost. +This goal was considered essential +because of the emphasis on mail in our environment. +It has turned out to be one of the hardest goals to satisfy, +especially in the face of the many anomalous message formats +produced by various ARPANET sites. +For example, +certain sites generate improperly formated addresses, +occasionally +causing error-message loops. +Some hosts use blanks in names, +causing problems with +mail programs that assume that an address +is one word. +The semantics of some fields +are interpreted slightly differently +by different sites. +In summary, +the obscure features of the ARPANET mail protocol +really +.i are +used and +are difficult to support, +but must be supported. +.np +Existing software to do actual delivery +should be used whenever possible. +This goal derives as much from political and practical considerations +as technical. +.np +Easy expansion to +fairly complex environments, +including multiple +connections to a single network type +(such as with multiple UUCP or Ethernets). +This goal requires consideration of the contents of an address +as well as its syntax +in order to determine which gateway to use. +.np +Configuration information should not be compiled into the code. +A single compiled program should be able to run as is at any site +(barring such basic changes as the CPU type or the operating system). +We have found this seemingly unimportant goal +to be critical in real life. +Besides the simple problems that occur when any program gets recompiled +in a different environment, +many sites like to +.q fiddle +with anything that they will be recompiling anyway. +.np +.i Sendmail +must be able to let various groups maintain their own mailing lists, +and let individuals specify their own forwarding, +without modifying the system alias file. +.np +Each user should be able to specify which mailer to execute +to process mail being delivered for him. +This feature allows users who are using specialized mailers +that use a different format to build their environment +without changing the system, +and facilitates specialized functions +(such as returning an +.q "I am on vacation" +message). +.np +Network traffic should be minimized +by batching addresses to a single host where possible, +without assistance from the user. +.pp +These goals motivated the architecture illustrated in figure 1. +.(z +.hl +.ie t \ +. sp 18 +.el \{\ +.(c ++---------+ +---------+ +---------+ +| sender1 | | sender2 | | sender3 | ++---------+ +---------+ +---------+ + | | | + +----------+ + +----------+ + | | | + v v v + +-------------+ + | sendmail | + +-------------+ + | | | + +----------+ + +----------+ + | | | + v v v ++---------+ +---------+ +---------+ +| mailer1 | | mailer2 | | mailer3 | ++---------+ +---------+ +---------+ +.)c +.\} + +.ce +Figure 1 \*- Sendmail System Structure. +.hl +.)z +The user interacts with a mail generating and sending program. +When the mail is created, +the generator calls +.i sendmail , +which routes the message to the correct mailer(s). +Since some of the senders may be network servers +and some of the mailers may be network clients, +.i sendmail +may be used as an internet mail gateway. +.sh 1 "USAGE" +.sh 2 "Address Formats" +.pp +Arguments may be flags or addresses. +Flags set various processing options. +Following flag arguments, +address arguments may be given. +Addresses follow the syntax in RFC822 +[Crocker82] +for ARPANET +address formats. +In brief, the format is: +.np +Anything in parentheses is thrown away +(as a comment). +.np +Anything in angle brackets (\c +.q "<\|>" ) +is preferred +over anything else. +This rule implements the ARPANET standard that addresses of the form +.(b +user name +.)b +will send to the electronic +.q machine-address +rather than the human +.q "user name." +.np +Double quotes +(\ "\ ) +quote phrases; +backslashes quote characters. +Backslashes are more powerful +in that they will cause otherwise equivalent phrases +to compare differently \*- for example, +.i user +and +.i +"user" +.r +are equivalent, +but +.i \euser +is different from either of them. +This might be used +to avoid normal aliasing +or duplicate suppression algorithms. +.pp +Parentheses, angle brackets, and double quotes +must be properly balanced and nested. +The rewriting rules control remaining parsing\**. +.(f +\**Disclaimer: Some special processing is done +after rewriting local names; see below. +.)f +.pp +Although old style addresses are still accepted +in most cases, +the preferred address format +is based on ARPANET-style domain-based addresses +[Su82a]. +These addresses are based on a hierarchical, logical decomposition +of the address space. +The addresses are hierarchical in a sense +similar to the U.S. postal addresses: +the messages may first be routed to the correct state, +with no initial consideration of the city +or other addressing details. +The addresses are logical +in that each step in the hierarchy +corresponds to a set of +.q "naming authorities" +rather than a physical network. +.pp +For example, +the address: +.(l +eric@HostA.BigSite.ARPA +.)l +would first look up the domain +BigSite +in the namespace administrated by +ARPA. +A query could then be sent to +BigSite +for interpretation of +HostA. +Eventually the mail would arrive at +HostA, +which would then do final delivery +to user +.q eric. +.sh 2 "Mail to Files and Programs" +.pp +Files and programs are legitimate message recipients. +Files provide archival storage of messages, +useful for project administration and history. +Programs are useful as recipients in a variety of situations, +for example, +to maintain a public repository of systems messages +(such as the Berkeley +.i msgs +program). +.pp +Any address passing through the initial parsing algorithm +as a local address +(i.e, not appearing to be a valid address for another mailer) +is scanned for two special cases. +If prefixed by a vertical bar (\c +.q \^|\^ ) +the rest of the address is processed as a shell command. +If the user name begins with a slash mark (\c +.q /\^ ) +the name is used as a file name, +instead of a login name. +.sh 2 "Aliasing, Forwarding, Inclusion" +.pp +.i Sendmail +reroutes mail three ways. +Aliasing applies system wide. +Forwarding allows each user to reroute incoming mail +destined for that account. +Inclusion directs +.i sendmail +to read a file for a list of addresses, +and is normally used +in conjunction with aliasing. +.sh 3 "Aliasing" +.pp +Aliasing maps local addresses to address lists using a system-wide file. +This file is hashed to speed access. +Only addresses that parse as local +are allowed as aliases; +this guarantees a unique key +(since there are no nicknames for the local host). +.sh 3 "Forwarding" +.pp +After aliasing, +if an recipient address specifies a local user +.i sendmail +searches for a +.q .forward +file in the recipient's home directory. +If it exists, +the message is +.i not +sent to that user, +but rather to the list of addresses in that file. +Often +this list will contain only one address, +and the feature will be used for network mail forwarding. +.pp +Forwarding also permits a user to specify a private incoming mailer. +For example, +forwarding to: +.(b +"\^|\|/usr/local/newmail myname" +.)b +will use a different incoming mailer. +.sh 3 "Inclusion" +.pp +Inclusion is specified in RFC 733 [Crocker77] syntax: +.(b +:Include: pathname +.)b +An address of this form reads the file specified by +.i pathname +and sends to all users listed in that file. +.pp +The intent is +.i not +to support direct use of this feature, +but rather to use this as a subset of aliasing. +For example, +an alias of the form: +.(b +project: :include:/usr/project/userlist +.)b +is a method of letting a project maintain a mailing list +without interaction with the system administration, +even if the alias file is protected. +.pp +It is not necessary to rebuild the index on the alias database +when a :include: list is changed. +.sh 2 "Message Collection" +.pp +Once all recipient addresses are parsed and verified, +the message is collected. +The message comes in two parts: +a message header and a message body, +separated by a blank line. +The body is an uninterpreted +sequence of text lines. +.pp +The header is formated as a series of lines +of the form +.(b + field-name: field-value +.)b +Field-value can be split across lines by starting the following +lines with a space or a tab. +Some header fields have special internal meaning, +and have appropriate special processing. +Other headers are simply passed through. +Some header fields may be added automatically, +such as time stamps. +.sh 1 "THE UUCP PROBLEM" +.pp +Of particular interest +is the UUCP network. +The explicit routing +used in the UUCP environment +causes a number of serious problems. +First, +giving out an address +is impossible +without knowing the address of your potential correspondent. +This is typically handled +by specifying the address +relative to some +.q "well-known" +host +(e.g., +ucbvax or decvax). +Second, +it is often difficult to compute +the set of addresses +to reply to +without some knowledge +of the topology of the network. +Although it may be easy for a human being +to do this +under many circumstances, +a program does not have equally sophisticated heuristics +built in. +Third, +certain addresses will become painfully and unnecessarily long, +as when a message is routed through many hosts in the USENET. +And finally, +certain +.q "mixed domain" +addresses +are impossible to parse unambiguously \*- +e.g., +.(l +decvax!ucbvax!lbl-h!user@LBL-CSAM +.)l +might have many possible resolutions, +depending on whether the message was first routed +to decvax +or to LBL-CSAM. +.pp +To solve this problem, +the UUCP syntax +would have to be changed to use addresses +rather than routes. +For example, +the address +.q decvax!ucbvax!eric +might be expressed as +.q eric@ucbvax.UUCP +(with the hop through decvax implied). +This address would itself be a domain-based address; +for example, +an address might be of the form: +.(l +mark@d.cbosg.btl.UUCP +.)l +Hosts outside of Bell Telephone Laboratories +would then only need to know +how to get to a designated BTL relay, +and the BTL topology +would only be maintained inside Bell. +.pp +There are three major problems +associated with turning UUCP addresses +into something reasonable: +defining the namespace, +creating and propagating the necessary software, +and building and maintaining the database. +.sh 2 "Defining the Namespace" +.pp +Putting all UUCP hosts into a flat namespace +(e.g., +.q \&...@host.UUCP ) +is not practical for a number of reasons. +First, +with over 1600 sites already, +and (with the increasing availability of inexpensive microcomputers +and autodialers) +several thousand more coming within a few years, +the database update problem +is simply intractable +if the namespace is flat. +Second, +there are almost certainly name conflicts today. +Third, +as the number of sites grow +the names become ever less mnemonic. +.pp +It seems inevitable +that there be some sort of naming authority +for the set of top level names +in the UUCP domain, +as unpleasant a possibility +as that may seem. +It will simply not be possible +to have one host resolving all names. +It may however be possible +to handle this +in a fashion similar to that of assigning names of newsgroups +in USENET. +However, +it will be essential to encourage everyone +to become subdomains of an existing domain +whenever possible \*- +even though this will certainly bruise some egos. +For example, +if a new host named +.q blid +were to be added to the UUCP network, +it would probably actually be addressed as +.q d.bli.UUCP +(i.e., +as host +.q d +in the pseudo-domain +.q bli +rather than as host +.q blid +in the UUCP domain). +.sh 2 "Creating and Propagating the Software" +.pp +The software required to implement a consistent namespace +is relatively trivial. +Two modules are needed, +one to handle incoming mail +and one to handle outgoing mail. +.pp +The incoming module +must be prepared to handle either old or new style addresses. +New-style addresses +can be passed through unchanged. +Old style addresses +must be turned into new style addresses +where possible. +.pp +The outgoing module +is slightly trickier. +It must do a database lookup on the recipient addresses +(passed on the command line) +to determine what hosts to send the message to. +If those hosts do not accept new-style addresses, +it must transform all addresses in the header of the message +into old style using the database lookup. +.pp +Both of these modules +are straightforward +except for the issue of modifying the header. +It seems prudent to choose one format +for the message headers. +For a number of reasons, +Berkeley has elected to use the ARPANET protocols +for message formats. +However, +this protocol is somewhat difficult to parse. +.pp +Propagation is somewhat more difficult. +There are a large number of hosts +connected to UUCP +that will want to run completely standard systems +(for very good reasons). +The strategy is not to convert the entire network \*- +only enough of it it alleviate the problem. +.sh 2 "Building and Maintaining the Database" +.pp +This is by far the most difficult problem. +A prototype for this database +already exists, +but it is maintained by hand +and does not pretend to be complete. +.pp +This problem will be reduced considerably +if people choose to group their hosts +into subdomains. +This would require a global update +only when a new top level domain +joined the network. +A message to a host in a subdomain +could simply be routed to a known domain gateway +for further processing. +For example, +the address +.q eric@a.bli.UUCP +might be routed to the +.q bli +gateway +for redistribution; +new hosts could be added +within BLI +without notifying the rest of the world. +Of course, +other hosts +.i could +be notified as an efficiency measure. +.pp +There may be more than one domain gateway. +A domain such as BTL, +for instance, +might have a dozen gateways to the outside world; +a non-BTL site +could choose the closest gateway. +The only restriction +would be that all gateways +maintain a consistent view of the domain +they represent. +.sh 2 "Logical Structure" +.pp +Logically, +domains are organized into a tree. +There need not be a host actually associated +with each level in the tree \*- +for example, +there will be no host associated with the name +.q UUCP. +Similarly, +an organization might group names together for administrative reasons; +for example, +the name +.(l +CAD.research.BigCorp.UUCP +.)l +might not actually have a host representing +.q research. +.pp +However, +it may frequently be convenient to have a host +or hosts +that +.q represent +a domain. +For example, +if a single host exists that +represents +Berkeley, +then mail from outside Berkeley +can forward mail to that host +for further resolution +without knowing Berkeley's +(rather volatile) +topology. +This is not unlike the operation +of the telephone network. +.pp +This may also be useful +inside certain large domains. +For example, +at Berkeley it may be presumed +that most hosts know about other hosts +inside the Berkeley domain. +But if they process an address +that is unknown, +they can pass it +.q upstairs +for further examination. +Thus as new hosts are added +only one host +(the domain master) +.i must +be updated immediately; +other hosts can be updated as convenient. +.pp +Ideally this name resolution process +would be performed by a name server +(e.g., [Su82b]) +to avoid unnecessary copying +of the message. +However, +in a batch network +such as UUCP +this could result in unnecessary delays. +.sh 1 "COMPARISON WITH DELIVERMAIL" +.pp +.i Sendmail +is an outgrowth of +.i delivermail . +The primary differences are: +.np +Configuration information is not compiled in. +This change simplifies many of the problems +of moving to other machines. +It also allows easy debugging of new mailers. +.np +Address parsing is more flexible. +For example, +.i delivermail +only supported one gateway to any network, +whereas +.i sendmail +can be sensitive to host names +and reroute to different gateways. +.np +Forwarding and +:include: +features eliminate the requirement that the system alias file +be writable by any user +(or that an update program be written, +or that the system administration make all changes). +.np +.i Sendmail +supports message batching across networks +when a message is being sent to multiple recipients. +.np +A mail queue is provided in +.i sendmail. +Mail that cannot be delivered immediately +but can potentially be delivered later +is stored in this queue for a later retry. +The queue also provides a buffer against system crashes; +after the message has been collected +it may be reliably redelivered +even if the system crashes during the initial delivery. +.np +.i Sendmail +uses the networking support provided by 4.2BSD +to provide a direct interface networks such as the ARPANET +and/or Ethernet +using SMTP (the Simple Mail Transfer Protocol) +over a TCP/IP connection. +.+c +.ce +REFERENCES +.nr ii 1.5i +.ip [Crocker77] +Crocker, D.

This file is +intended as a supplement to the CERT advisory CA-93:16.sendmail.vulnerability, +and to the software, smrsh.c, written by Eric Allman. + + + +The smrsh(8) program is intended as a replacement for /bin/sh in the +program mailer definition of sendmail(8). This README file describes +the steps needed to compile and install smrsh. + +smrsh is a restricted shell utility that provides the ability to +specify, through a configuration, an explicit list of executable +programs. When used in conjunction with sendmail, smrsh effectively +limits sendmail's scope of program execution to only those programs +specified in smrsh's configuration. + +smrsh has been written with portability in mind, and uses traditional +Unix library utilities. As such, smrsh should compile on most +Unix C compilers. + + + +To compile smrsh.c, use the following command: + +host.domain% cc -o smrsh smrsh.c + +For machines that provide dynamic linking, it is advisable to compile +smrsh without dynamic linking. As an example with the Sun Microsystems +compiler, you should compile with the -Bstatic option. + +host.domain% cc -Bstatic -o smrsh smrsh.c + + +Choose a directory that smrsh will reside in. We will use the traditional +/usr/local/etc directory for the remainder of this document. + +As root, install smrsh in /usr/local/etc directory, with mode 511. + +host.domain# mv smrsh /usr/local/etc +host.domain# chmod 511 /usr/local/etc/smrsh + + + +Next, determine the list of commands that smrsh should allow sendmail +to run. This list of allowable commands can be determined by: + + 1. examining your /etc/aliases file, to indicate what commands + are being used by the system. + + 2. surveying your host's .forward files, to determine what + commands users have specified. + +See the man page for aliases(5) if you are unfamiliar with the format of +these specifications. Additionally, you should include in the list, +popular commands such as /usr/ucb/vacation. + +You should NOT include interpreter programs such as sh(1), csh(1), +perl(1), uudecode(1) or the stream editor sed(1) in your list of +acceptable commands. + + +You will next need to create the directory /usr/adm/sm.bin and populate +it with the programs that your site feels are allowable for sendmail +to execute. This directory is explicitly specified in the source +code for smrsh, so changing this directory must be accompanied with +a change in smrsh.c. + + +You will have to be root to make these modifications. + +After creating the /usr/adm/sm.bin directory, either copy the programs +to the directory, or establish links to the allowable programs from +/usr/adm/sm.bin. Change the file permissions, so that these programs +can not be modified by non-root users. If you use links, you should +ensure that the target programs are not modifiable. + +To allow the popular vacation(1) program by creating a link in the +/usr/adm/sm.bin directory, you should: + +host.domain# cd /usr/adm/sm.bin +host.domain# ln -s /usr/ucb/vacation vacation + + + + +After populating the /usr/adm/sm.bin directory, you can now configure +sendmail to use the restricted shell. Save the current sendmail.cf +file prior to modifying it, as a prudent precaution. + +Typically, the program mailer is defined by a single line in the +sendmail configuration file, sendmail.cf. This file is traditionally +found in the /etc, /usr/lib or /etc/mail directories, depending on +the UNIX vendor. + +If you are unsure of the location of the actual sendmail configuration +file, a search of the strings(1) output of the sendmail binary, will +help to locate it. + +In order to configure sendmail to use smrsh, you must modify the Mprog +definition in the sendmail.cf file, by replacing the /bin/sh specification +with /usr/local/etc/smrsh. + +As an example: + +In most Sun Microsystems' sendmail.cf files, the line is: +Mprog, P=/bin/sh, F=lsDFMeuP, S=10, R=20, A=sh -c $u + +which should be changed to: +Mprog, P=/usr/local/etc/smrsh, F=lsDFMeuP, S=10, R=20, A=sh -c $u + ^^^^^^^^^^^^^^^^^^^^ + +A more generic line may be: +Mprog, P=/bin/sh, F=lsDFM, A=sh -c $u + +and should be changed to; +Mprog, P=/usr/local/etc/smrsh, F=lsDFM, A=sh -c $u + + +After modifying the Mprog definition in the sendmail.cf file, if a frozen +configuration file is being used, it is essential to create a new one. +You can determine if you need a frozen configuration by discovering +if a sendmail.fc file currently exists in either the /etc/, /usr/lib, +or /etc/mail directories. The specific location can be determined using +a search of the strings(1) output of the sendmail binary. + +In order to create a new frozen configuration, if it is required: +host.domain# /usr/lib/sendmail -bz + +Now re-start the sendmail process. An example of how to do this on +a typical system follows: + +host.domain# /usr/bin/ps aux | /usr/bin/grep sendmail +root 130 0.0 0.0 168 0 ?

It also creates a +subdirectory per object format, so that multiarchitecture support is +easy. In general this should be all you need. IRIX 6.x users should +read the note below in the OPERATING SYSTEM AND COMPILE QUIRKS section. + +If you need to look at other include or library directories, use the +-I or -L flags on the command line, e.g., + + sh Build -I/usr/sww/include -L/usr/sww/lib + +It's also possible to create local site configuration in the file +site.config.m4 (or another file settable with the -f flag). This +file contains M4 definitions for various compilation values; the +most useful are: + +confMAPDEF -D flags to specify database types to be included + (see below) +confENVDEF -D flags to specify other environment information +confINCDIRS -I flags for finding include files during compilation +confLIBDIRS -L flags for finding libraries during linking +confLIBS -l flags for selecting libraries during linking +confLDOPTS other ld(1) linker options + +Others can be found by examining Makefile.m4. Please read +../BuildTools/README for more information about the site.config.m4 +file. + +You can recompile from scratch using the -c flag with the Build +command. This removes the existing compilation directory for the +current platform and builds a new one. + +Porting to a new Unix-based system should be a matter of creating +an appropriate configuration file in the BuildTools/OS/ directory. + + + ++----------------------+ +| DATABASE DEFINITIONS | ++----------------------+ + +There are several database formats that can be used for the alias files +and for general maps. When used for alias files they interact in an +attempt to be backward compatible. + +The options are: + +NEWDB The new Berkeley DB package. Some systems (e.g., BSD/OS and + Digital UNIX 4.0) have some version of this package + pre-installed. If your system does not have Berkeley DB + pre-installed, or the version installed is not version 2.0 + or greater (e.g., is Berkeley DB 1.85 or 1.86), get the + current version from http://www.sleepycat.com/. DO NOT + use a version from any of the University of California, + Berkeley "Net" or other distributions. If you are still + running BSD/386 1.x, you will need to upgrade the included + Berkeley DB library to a current version. NEWDB is included + automatically if the Build script can find a library named + libdb.a. +NDBM The older NDBM implementation -- the very old V7 DBM + implementation is no longer supported. +NIS Network Information Services. To use this you must have + NIS support on your system. +NISPLUS NIS+ (the revised NIS released with Solaris 2). You must + have NIS+ support on your system to use this flag. +HESIOD Support for Hesiod (from the DEC/Athena distribution). You + must already have Hesiod support on your system for this to + work. You may be able to get this to work with the MIT/Athena + version of Hesiod, but that's likely to be a lot of work. +LDAPMAP Lightweight Directory Lookup Protocol support. You will + have to install the UMich ldap and lber libraries to use + this flag. +MAP_REGEX Regular Expression support. You will need to use an + operating system which comes with the POSIX regex() + routines or install a regexp library such as libregex from + the Free Software Foundation. + +>>> NOTE WELL for NEWDB support: If you want to get ndbm support, for +>>> Berkeley DB versions under 2.0, it is CRITICAL that you remove +>>> ndbm.o from libdb.a before you install it and DO NOT install ndbm.h; +>>> for Berkeley DB versions 2.0 through 2.3.14, remove dbm.o from libdb.a +>>> before you install it. If you don't delete these, there is absolutely +>>> no point to including -DNDBM, since it will just get you another +>>> (inferior) API to the same format database. These files OVERRIDE +>>> calls to ndbm routines -- in particular, if you leave ndbm.h in, +>>> you can find yourself using the new db package even if you don't +>>> define NEWDB. Berkeley DB versions later than 2.3.14 do not need +>>> to be modified. Please also consult the README in the top level +>>> directory of the sendmail distribution for other important information. +>>> +>>> Further note: DO NOT remove your existing /usr/include/ndbm.h -- +>>> you need that one. But do not install an updated ndbm.h in +>>> /usr/include, /usr/local/include, or anywhere else. + +If NEWDB and NDBM are defined (but not NIS), then sendmail will read +NDBM format alias files, but the next time a newaliases is run the +format will be converted to NEWDB; that format will be used forever +more. This is intended as a transition feature. + +If NEWDB, NDBM, and NIS are all defined and the name of the file includes +the string "/yp/", sendmail will rebuild BOTH the NEWDB and NDBM format +alias files. However, it will only read the NEWDB file; the NDBM format +file is used only by the NIS subsystem. This is needed because the NIS +maps on an NIS server are built directly from the NDBM files. + +If NDBM and NIS are defined (regardless of the definition of NEWDB), +and the filename includes the string "/yp/", sendmail adds the special +tokens "YP_LAST_MODIFIED" and "YP_MASTER_NAME", both of which are +required if the NDBM file is to be used as an NIS map. + +All of these flags are normally defined in the DBMDEF line in the +Makefile. + +If you define NEWDB or HESIOD you get the User Database (USERDB) +automatically. Generally you do want to have NEWDB for it to do +anything interesting. See above for getting the Berkeley DB +package (i.e., NEWDB). There is no separate "user database" +package -- don't bother searching for it on the net. + +Hesiod and LDAP require libraries that may not be installed with your +system. These are outside of my ability to provide support. See the +"Quirks" section for more information. + +The regex map can be used to see if an address matches a certain regular +expression. For example, all-numerics local parts are common spam +addresses, so "^[0-9]+$" would match this. By using such a map in a +check_* rule-set, you can block a certain range of addresses that would +otherwise be considered valid. + ++---------------+ +| COMPILE FLAGS | ++---------------+ + +Wherever possible, I try to make sendmail pull in the correct +compilation options needed to compile on various environments based on +automatically defined symbols. Some machines don't seem to have useful +symbols available, requiring that a compilation flag be defined in +the Makefile; see the Buildtools/OS subdirectory for the supported +architectures. + +If you are a system to which sendmail has already been ported you +should not have to touch the following symbols. But if you are porting, +you may have to tweak the following compilation flags in conf.h in order +to get it to compile and link properly: + +SYSTEM5 Adjust for System V (not necessarily Release 4). +SYS5SIGNALS Use System V signal semantics -- the signal handler + is automatically dropped when the signal is caught. + If this is not set, use POSIX/BSD semantics, where the + signal handler stays in force until an exec or an + explicit delete. Implied by SYSTEM5. +SYS5SETPGRP Use System V setpgrp() semantics. Implied by SYSTEM5. +HASFCHMOD Define this to one if you have the fchmod(2) system call. + This improves security. +HASFLOCK Set this if you prefer to use the flock(2) system call + rather than using fcntl-based locking. Fcntl locking + has some semantic gotchas, but many vendor systems + also interface it to lockd(8) to do NFS-style locking. + Unfortunately, may vendors implementations of fcntl locking + is just plain broken (e.g., locks are never released, + causing your sendmail to deadlock; when the kernel runs + out of locks your system crashes). For this reason, I + recommend always defining this unless you are absolutely + certain that your fcntl locking implementation really works. +HASUNAME Set if you have the "uname" system call. Implied by + SYSTEM5. +HASUNSETENV Define this if your system library has the "unsetenv" + subroutine. +HASSETSID Define this if you have the setsid(2) system call. This + is implied if your system appears to be POSIX compliant. +HASINITGROUPS Define this if you have the initgroups(3) routine. +HASSETVBUF Define this if you have the setvbuf(3) library call. + If you don't, setlinebuf will be used instead. This + defaults on if your compiler defines __STDC__. +HASSETREUID Define this if you have setreuid(2) ***AND*** root can + use setreuid to change to an arbitrary user. This second + condition is not satisfied on AIX 3.x. You may find that + your system has setresuid(2), (for example, on HP-UX) in + which case you will also have to #define setreuid(r, e) + to be the appropriate call. Some systems (such as Solaris) + have a compatibility routine that doesn't work properly, + but may have "saved user ids" properly implemented so you + can ``#define setreuid(r, e) seteuid(e)'' and have it work. + The important thing is that you have a call that will set + the effective uid independently of the real or saved uid + and be able to set the effective uid back again when done. + There's a test program in ../test/t_setreuid.c that will + try things on your system. Setting this improves the + security, since sendmail doesn't have to read .forward + and :include: files as root. There are certain attacks + that may be unpreventable without this call. +USESETEUID Define this to 1 if you have a seteuid(2) system call that + will allow root to set only the effective user id to an + arbitrary value ***AND*** you have saved user ids. This is + preferable to HASSETREUID if these conditions are fulfilled. + These are the semantics of the to-be-released revision of + Posix.1. The test program ../test/t_seteuid.c will try + this out on your system. If you define both HASSETREUID + and USESETEUID, the former is ignored. +HASLSTAT Define this if you have symbolic links (and thus the + lstat(2) system call). This improves security. Unlike + most other options, this one is on by default, so you + need to #undef it in conf.h if you don't have symbolic + links (these days everyone does). +HASSETRLIMIT Define this to 1 if you have the setrlimit(2) syscall. + You can define it to 0 to force it off. It is assumed + if you are running a BSD-like system. +HASULIMIT Define this if you have the ulimit(2) syscall (System V + style systems). HASSETRLIMIT overrides, as it is more + general. +HASWAITPID Define this if you have the waitpid(2) syscall. +HASGETDTABLESIZE + Define this if you have the getdtablesize(2) syscall. +HAS_ST_GEN Define this to 1 if your system has the st_gen field in + the stat structure (see stat(2)). +USESTRERROR Define this if you have the libc strerror function (which + should be declared in ), and it should be used + instead of sys_errlist. +NEEDGETOPT Define this if you need a reimplementation of getopt(3). + On some systems, getopt does very odd things if called + to scan the arguments twice. This flag will ask sendmail + to compile in a local version of getopt that works + properly. +NEEDSTRTOL Define this if your standard C library does not define + strtol(3). This will compile in a local version. +NEEDVPRINTF Define this if your standard C library does not define + vprintf(3). Note that the resulting fake implementation + is not very elegant and may not even work on some + architectures. +NEEDFSYNC Define this if your standard C library does not define + fsync(2). This will try to simulate the operation using + fcntl(2); if that is not available it does nothing, which + isn't great, but at least it compiles and runs. +HASGETUSERSHELL Define this to 1 if you have getusershell(3) in your + standard C library. If this is not defined, or is defined + to be 0, sendmail will scan the /etc/shells file (no + NIS-style support, defaults to /bin/sh and /bin/csh if + that file does not exist) to get a list of unrestricted + user shells. This is used to determine whether users + are allowed to forward their mail to a program or a file. +NEEDPUTENV Define this if your system needs am emulation of the + putenv(3) call. Define to 1 to implement it in terms + of setenv(3) or to 2 to do it in terms of primitives. +NOFTRUNCATE Define this if you don't have the ftruncate(2) syscall. + If you don't have this system call, there is an unavoidable + race condition that occurs when creating alias databases. +GIDSET_T The type of entries in a gidset passed as the second + argument to getgroups(2). Historically this has been an + int, so this is the default, but some systems (such as + IRIX) pass it as a gid_t, which is an unsigned short. + This will make a difference, so it is important to get + this right! However, it is only an issue if you have + group sets. +SLEEP_T The type returned by the system sleep() function. + Defaults to "unsigned int". Don't worry about this + if you don't have compilation problems. +ARBPTR_T The type of an arbitrary pointer -- defaults to "void *". + If you are an very old compiler you may need to define + this to be "char *". +SOCKADDR_LEN_T The type used for the third parameter to accept(2), + getsockname(2), and getpeername(2), representing the + length of a struct sockaddr. Defaults to int. +SOCKOPT_LEN_T The type used for the fifth parameter to getsockopt(2) + and setsockopt(2), representing the length of the option + buffer. Defaults to int. +LA_TYPE The type of load average your kernel supports. These + can be one of: + LA_ZERO (1) -- it always returns the load average as + "zero" (and does so on all architectures). + LA_INT (2) to read /dev/kmem for the symbol avenrun and + interpret as a long integer. + LA_FLOAT (3) same, but interpret the result as a floating + point number. + LA_SHORT (6) to interpret as a short integer. + LA_SUBR (4) if you have the getloadavg(3) routine in your + system library. + LA_MACH (5) to use MACH-style load averages (calls + processor_set_info()), + LA_PROCSTR (7) to read /proc/loadavg and interpret it + as a string representing a floating-point + number (Linux-style). + LA_READKSYM (8) is an implementation suitable for some + versions of SVr4 that uses the MIOC_READKSYM ioctl + call to read /dev/kmem. + LA_DGUX (9) is a special implementation for DG/UX that uses + the dg_sys_info system call. + LA_HPUX (10) is an HP-UX specific version that uses the + pstat_getdynamic system call. + LA_IRIX6 (11) is an IRIX 6.x specific version that adapts + to 32 or 64 bit kernels; it is otherwise very similar + to LA_INT. + LA_KSTAT (12) uses the (Solaris-specific) kstat(3k) + implementation. + LA_DEVSHORT (13) reads a short from a system file (default: + /dev/table/avenrun) and scales it in the same manner + as LA_SHORT. + LA_INT, LA_SHORT, LA_FLOAT, and LA_READKSYM have several + other parameters that they try to divine: the name of your + kernel, the name of the variable in the kernel to examine, + the number of bits of precision in a fixed point load average, + and so forth. LA_DEVSHORT uses _PATH_AVENRUN to find the + device to be read to find the load average. + In desperation, use LA_ZERO. The actual code is in + conf.c -- it can be tweaked if you are brave. +FSHIFT For LA_INT, LA_SHORT, and LA_READKSYM, this is the number + of bits of load average after the binary point -- i.e., + the number of bits to shift right in order to scale the + integer to get the true integer load average. Defaults to 8. +_PATH_UNIX The path to your kernel. Needed only for LA_INT, LA_SHORT, + and LA_FLOAT. Defaults to "/unix" on System V, "/vmunix" + everywhere else. +LA_AVENRUN For LA_INT, LA_SHORT, and LA_FLOAT, the name of the kernel + variable that holds the load average. Defaults to "avenrun" + on System V, "_avenrun" everywhere else. +SFS_TYPE Encodes how your kernel can locate the amount of free + space on a disk partition. This can be set to SFS_NONE + (0) if you have no way of getting this information, + SFS_USTAT (1) if you have the ustat(2) system call, + SFS_4ARGS (2) if you have a four-argument statfs(2) + system call (and the include file is ), + SFS_VFS (3), SFS_MOUNT (4), SFS_STATFS (5) if you have + the two-argument statfs(2) system call with includes in + , , or respectively, + or SFS_STATVFS (6) if you have the two-argument statvfs(2) + call. The default if nothing is defined is SFS_NONE. +SFS_BAVAIL with SFS_4ARGS you can also set SFS_BAVAIL to the field name + in the statfs structure that holds the useful information; + this defaults to f_bavail. +SPT_TYPE Encodes how your system can display what a process is doing + on a ps(1) command (SPT stands for Set Process Title). Can + be set to: + SPT_NONE (0) -- Don't try to set the process title at all. + SPT_REUSEARGV (1) -- Pad out your argv with the information; + this is the default if none specified. + SPT_BUILTIN (2) -- The system library has setproctitle. + SPT_PSTAT (3) -- Use the PSTAT_SETCMD option to pstat(2) + to set the process title; this is used by HP-UX. + SPT_PSSTRINGS (4) -- Use the magic PS_STRINGS pointer (4.4BSD). + SPT_SYSMIPS (5) -- Use sysmips() supported by NEWS-OS 6. + SPT_SCO (6) -- Write kernel u. area. + SPT_CHANGEARGV (7) -- Write pointers to our own strings into + the existing argv vector. +SPT_PADCHAR Character used to pad the process title; if undefined, + the space character (0x20) is used. This is ignored if + SPT_TYPE != SPT_REUSEARGV +ERRLIST_PREDEFINED + If set, assumes that some header file defines sys_errlist. + This may be needed if you get type conflicts on this + variable -- otherwise don't worry about it. +WAITUNION The wait(2) routine takes a "union wait" argument instead + of an integer argument. This is for compatibility with + old versions of BSD. +SCANF You can set this to extend the F command to accept a + scanf string -- this gives you a primitive parser for + class definitions -- BUT it can make you vulnerable to + core dumps if the target file is poorly formed. +SYSLOG_BUFSIZE You can define this to be the size of the buffer that + syslog accepts. If it is not defined, it assumes a + 1024-byte buffer. If the buffer is very small (under + 256 bytes) the log message format changes -- each + e-mail message will log many more messages, since it + will log each piece of information as a separate line + in syslog. +BROKEN_RES_SEARCH + On Ultrix (and maybe other systems?) if you use the + res_search routine with an unknown host name, it returns + -1 but sets h_errno to 0 instead of HOST_NOT_FOUND. If + you set this, sendmail considers 0 to be the same as + HOST_NOT_FOUND. +NAMELISTMASK If defined, values returned by nlist(3) are masked + against this value before use -- a common value is + 0x7fffffff to strip off the top bit. +BSD4_4_SOCKADDR If defined, socket addresses have an sa_len field that + defines the length of this address. +SAFENFSPATHCONF Set this to 1 if and only if you have verified that a + pathconf(2) call with _PC_CHOWN_RESTRICTED argument on an + NFS filesystem where the underlying system allows users to + give away files to other users returns <= 0. Be sure you + try both on NFS V2 and V3. Some systems assume that their + local policy apply to NFS servers -- this is a bad + assumption! The test/t_pathconf.c program will try this + for you -- you have to run it in a directory that is + mounted from a server that allows file giveaway. +SIOCGIFCONF_IS_BROKEN + Set this if your system has an SIOCGIFCONF ioctl defined, + but it doesn't behave the same way as "most" systems (BSD, + Solaris, SunOS, HP-UX, etc.) +SIOCGIFNUM_IS_BROKEN + Set this if your system has an SIOCGIFNUM ioctl defined, + but it doesn't behave the same way as "most" systems + (Solaris, HP-UX). +NEED_PERCENTQ Set this if your system doesn't support the printf + format strings %lld or %llu. If this is set, %qd and + %qu are used instead. + + + ++-----------------------+ +| COMPILE-TIME FEATURES | ++-----------------------+ + +There are a bunch of features that you can decide to compile in, such +as selecting various database packages and special protocol support. +Several are assumed based on other compilation flags -- if you want to +"un-assume" something, you probably need to edit conf.h. Compilation +flags that add support for special features include: + +NDBM Include support for "new" DBM library for aliases and maps. + Normally defined in the Makefile. +NEWDB Include support for Berkeley DB package (hash & btree) + for aliases and maps. Normally defined in the Makefile. + If the version of NEWDB you have is the old one that does + not include the "fd" call (this call was added in version + 1.5 of the Berkeley DB code), you must upgrade to the + current version of Berkeley DB. +NIS Define this to get NIS (YP) support for aliases and maps. + Normally defined in the Makefile. +NISPLUS Define this to get NIS+ support for aliases and maps. + Normally defined in the Makefile. +HESIOD Define this to get Hesiod support for aliases and maps. + Normally defined in the Makefile. +NETINFO Define this to get NeXT NetInfo support for aliases and maps. + Normally defined in the Makefile. +USERDB Define this to 1 to include support for the User Information + Database. Implied by NEWDB or HESIOD. You can use + -DUSERDB=0 to explicitly turn it off. +IDENTPROTO Define this as 1 to get IDENT (RFC 1413) protocol support. + This is assumed unless you are running on Ultrix or + HP-UX, both of which have a problem in the UDP + implementation. You can define it to be 0 to explicitly + turn off IDENT protocol support. If defined off, the code + is actually still compiled in, but it defaults off; you + can turn it on by setting the IDENT timeout to 30s in the + configuration file. +IP_SRCROUTE Define this to 1 to get IP source routing information + displayed in the Received: header. This is assumed on + most systems, but some (e.g., Ultrix) apparently have a + broken version of getsockopt that doesn't properly + support the IP_OPTIONS call. You probably want this if + your OS can cope with it. Symptoms of failure will be that + it won't compile properly (that is, no support for fetching + IP_OPTIONs), or it compiles but source-routed TCP connections + either refuse to open or open and hang for no apparent reason. + Ultrix and AIX3 are known to fail this way. +LOG Set this to get syslog(3) support. Defined by default + in conf.h. You want this if at all possible. +NETINET Set this to get TCP/IP support. Defined by default + in conf.h. You probably want this. +NETISO Define this to get ISO networking support. +NETUNIX Define this to get Unix domain networking support. Defined + by default. A few bizarre systems (SCO, ISC, Altos) don't + support this networking domain. +SMTP Define this to get the SMTP code. Implied by NETINET + or NETISO. +NAMED_BIND If non-zero, include DNS (name daemon) support, including + MX support. The specs say you must use this if you run + SMTP. You don't have to be running a name server daemon + on your machine to need this -- any use of the DNS resolver, + including remote access to another machine, requires this + option. Defined by default in conf.h. Define it to zero + ONLY on machines that do not use DNS in any way. +QUEUE Define this to get queueing code. Implied by NETINET + or NETISO; required by SMTP. This gives you other good + stuff -- it should be on. +DAEMON Define this to get general network support. Implied by + NETINET or NETISO. Defined by default in conf.h. You + almost certainly want it on. +MATCHGECOS Permit fuzzy matching of user names against the full + name (GECOS) field in the /etc/passwd file. This should + probably be on, since you can disable it from the config + file if you want to. Defined by default in conf.h. +MIME8TO7 If non-zero, include 8 to 7 bit MIME conversions. This + also controls advertisement of 8BITMIME in the ESMTP + startup dialogue. +MIME7TO8 If non-zero, include 7 to 8 bit MIME conversions. +HES_GETMAILHOST Define this to 1 if you are using Hesiod with the + hes_getmailhost() routine. This is included with the MIT + Hesiod distribution, but not with the DEC Hesiod distribution. +XDEBUG Do additional internal checking. These don't cost too + much; you might as well leave this on. +TCPWRAPPERS Turns on support for the TCP wrappers library (-lwrap). + See below for further information. +SECUREWARE Enable calls to the SecureWare luid enabling/changing routines. + SecureWare is a C2 security package added to several UNIX's + (notably ConvexOS) to get a C2 Secure system. This + option causes mail delivery to be done with the luid of the + recipient. +SHARE_V1 Support for the fair share scheduler, version 1. Setting to + 1 causes final delivery to be done using the recipients + resource limitations. So far as I know, this is only + supported on ConvexOS. + + ++---------------------+ +| DNS/RESOLVER ISSUES | ++---------------------+ + +Many systems have old versions of the resolver library. At a minimum, +you should be running BIND 4.8.3; older versions may compile, but they +have known bugs that should give you pause. + +Common problems in old versions include "undefined" errors for +dn_skipname. + +Some people have had a problem with BIND 4.9; it uses some routines +that it expects to be externally defined such as strerror(). It may +help to link with "-l44bsd" to solve this problem. This has apparently +been fixed in later versions of BIND, starting around 4.9.3. In other +words, if you use 4.9.0 through 4.9.2, you need -l44bsd; for earlier or +later versions, you do not. + +!PLEASE! be sure to link with the same version of the resolver as +the header files you used -- some people have used the 4.9 headers +and linked with BIND 4.8 or vice versa, and it doesn't work. +Unfortunately, it doesn't fail in an obvious way -- things just +subtly don't work. + +WILDCARD MX RECORDS ARE A BAD IDEA! The only situation in which they +work reliably is if you have two versions of DNS, one in the real world +which has a wildcard pointing to your firewall, and a completely +different version of the database internally that does not include +wildcard MX records that match your domain. ANYTHING ELSE WILL GIVE +YOU HEADACHES! + + ++-------------------------------------+ +| OPERATING SYSTEM AND COMPILE QUIRKS | ++-------------------------------------+ + +GCC problems + ***************************************************************** + ** IMPORTANT: DO NOT USE OPTIMIZATION (``-O'') IF YOU ARE ** + ** RUNNING GCC 2.4.x or 2.5.x. THERE IS A BUG IN THE GCC ** + ** OPTIMIZER THAT CAUSES SENDMAIL COMPILES TO FAIL MISERABLY. ** + ***************************************************************** + + Jim Wilson of Cygnus believes he has found the problem -- it will + probably be fixed in GCC 2.5.6 -- but until this is verified, be + very suspicious of gcc -O. This problem is reported to have been + fixed in gcc 2.6. + + A bug in gcc 2.5.5 caused problems compiling sendmail 8.6.5 with + optimization on a Sparc. If you are using gcc 2.5.5, youi should + upgrade to the latest version of gcc. + + Apparently GCC 2.7.0 on the Pentium processor has optimization + problems. I recommend against using -O on that architecture. This + has been seen on FreeBSD 2.0.5 RELEASE. + + Solaris 2.X users should use version 2.7.2.3 over 2.7.2. + + We have been told there are problems with gcc 2.8.0. If you are + using this version, you should upgrade to 2.8.1 or later. + +GDBM GDBM does not work with sendmail 8.8 because the additional + security checks and file locking cause problems. Unfortunately, + gdbm does not provide a compile flag in its version of ndbm.h so + the code can adapt. Until the GDBM authors can fix these problems, + GDBM will not be supported. Please use Berkeley DB instead. + +Configuration file location + Up to 8.6, sendmail tried to find the sendmail.cf file in the same + place as the vendors had put it, even when this was obviously + stupid. As of 8.7, sendmail ALWAYS looks for /etc/sendmail.cf. + Beginning with 8.10, sendmail will use /etc/mail/sendmail.cf. + You can get sendmail to use the stupid vendor .cf location by + adding -DUSE_VENDOR_CF_PATH during compilation, but this may break + support programs and scripts that need to find sendmail.cf. You + are STRONGLY urged to use symbolic links if you want to use the + vendor location rather than changing the location in the sendmail + binary. + +SunOS 4.x (Solaris 1.x) + You may have to use -lresolv on SunOS. However, beware that + this links in a new version of gethostbyname that does not + understand NIS, so you must have all of your hosts in DNS. + + Some people have reported problems with the SunOS version of + -lresolv and/or in.named, and suggest that you get a newer + version. The symptoms are delays when you connect to the + SMTP server on a SunOS machine or having your domain added to + addresses inappropriately. There is a version of BIND + version 4.9 on gatekeeper.DEC.COM in pub/BSD/bind/4.9. + + There is substantial disagreement about whether you can make + this work with resolv+, which allows you to specify a search-path + of services. Some people report that it works fine, others + claim it doesn't work at all (including causing sendmail to + drop core when it tries to do multiple resolv+ lookups for a + single job). I haven't tried resolv+, as we use DNS exclusively. + + Should you want to try resolv+, it is on ftp.uu.net in + /networking/ip/dns. + + Apparently getservbyname() can fail under moderate to high + load under some circumstances. This will exhibit itself as + the message ``554 makeconnection: service "smtp" unknown''. + The problem has been traced to one or more blank lines in + /etc/services on the NIS server machine. Delete these + and it should work.

According + to Sun bug number 1077939: + + If an application does a getsockopt() on a SOCK_STREAM (TCP) socket + after the other side of the connection has sent a TCP RESET for + the stream, the kernel gets a Bus Trap in the tcp_ctloutput() or + ip_ctloutput() routine. + + For 4.1.3, this is fixed in patch 100584-08, available on the + Sunsolve 2.7.1 or later CDs. For 4.1.3_U1, this was fixed in patch + 101790-01 (SunOS 4.1.3_U1: TCP socket and reset problems), later + obsoleted by patch 102010-05. + + Sun patch 100584-08 is not currently publicly available on their + ftp site but a user has reported it can be found at other sites + using a web search engine. + +Solaris 2.x (SunOS 5.x) + To compile for Solaris, the Makefile built by Build must + include a SOLARIS definition which reflects the Solaris version + (i.e. -DSOLARIS=20400 for 2.4 or -DSOLARIS=20501 for 2.5.1). + If you are using gcc, make sure -I/usr/include is not used (or + it might complain about TopFrame). If you are using Sun's cc, + make sure /opt/SUNWspro/bin/cc is used instead of /usr/ucb/cc + (or it might complain about tm_zone). + + To the best of my knowledge, Solaris does not have the + gethostbyname problem described above. However, it does + have another one: + + From a correspondent: + + For solaris 2.2, I have + + hosts: files dns + + in /etc/nsswitch.conf and /etc/hosts has to have the fully + qualified host name. I think "files" has to be before "dns" + in /etc/nsswitch.conf during bootup. + + From another correspondent: + + When running sendmail under Solaris, the gethostbyname() + hack in conf.c which should perform proper canonicalization + of host names could fail. Result: the host name is not + canonicalized despite the hack, and you'll have to define $j + and $m in sendmail.cf somewhere. + + The reason could be that /etc/nsswitch.conf is improperly + configured (at least from sendmail's point of view). For + example, the line + + hosts: files nisplus dns + + will make gethostbyname() look in /etc/hosts first, then ask + nisplus, then dns. However, if /etc/hosts does not contain + the full canonicalized hostname, then no amount of + gethostbyname()s will work. + + Solution (or rather, a workaround): Ask nisplus first, then + dns, then local files: + + hosts: nisplus dns [NOTFOUND=return] files + + The Solaris "syslog" function is apparently limited to something + about 90 characters because of a kernel limitation. If you have + source code, you can probably up this number. You can get patches + that fix this problem: the patch ids are: + + Solaris 2.1 100834 + Solaris 2.2 100999 + Solaris 2.3 101318 + + Be sure you have the appropriate patch installed or you won't + see system logging. + +Solaris 2.4 (SunOS 5.4) + If you include /usr/lib at the end of your LD_LIBRARY_PATH you run + the risk of getting the wrong libraries under some circumstances. + This is because of a new feature in Solaris 2.4, described by + Rod.Evans@Eng.Sun.COM: + + >> Prior to SunOS 5.4, any LD_LIBRARY_PATH setting was ignored by the + >> runtime linker if the application was setxid (secure), thus your + >> applications search path would be: + >> + >> /usr/local/lib LD_LIBRARY_PATH component - IGNORED + >> /usr/lib LD_LIBRARY_PATH component - IGNORED + >> /usr/local/lib RPATH - honored + >> /usr/lib RPATH - honored + >> + >> the effect is that path 3 would be the first used, and this would + >> satisfy your resolv.so lookup. + >> + >> In SunOS 5.4 we made the LD_LIBRARY_PATH a little more flexible. + >> People who developed setxid applications wanted to be able to alter + >> the library search path to some degree to allow for their own + >> testing and debugging mechanisms.

The problem is fixed in 3.2C. + + Digital's mail delivery agent, /bin/mail (aka /bin/binmail), will + only preserve the envelope sender in the "From " header if + DefaultUserID is set to daemon. Setting this to mailnull will + cause all mail to have the header "From mailnull ...". To use + a different DefaultUserID, you will need to use a different mail + delivery agent (such as mail.local found in the sendmail + distribution). + + On Digital UNIX 4.0 and later, Berkeley DB 1.85 is included with the + operating system and already has the ndbm.o module removed. However, + Digital has modified the original Berkeley DB db.h include file. + This results in the following warning while compiling map.c and udb.c: + + cc: Warning: /usr/include/db.h, line 74: The redefinition of the macro + "__signed" conflicts with a current definition because the replacement + lists differ.

You should + be able to work around this by including the line: + + OOPort=25 + + in your .cf file. + + You may have to use -DNeXT. + +BSDI (BSD/386) 1.0, NetBSD 0.9, FreeBSD 1.0 + The "m4" from BSDI won't handle the config files properly. + I haven't had a chance to test this myself. + + The M4 shipped in FreeBSD and NetBSD 0.9 don't handle the config + files properly.

NetBSD-current may have + it too but it has not been verified. + + The latest version of Berkeley DB uses a different naming + scheme than the version that is supplied with your release. This + means you will be able to use the current version of Berkeley DB + with sendmail as long you use the new db.h when compiling + sendmail and link it against the new libdb.a. You should probably + keep the original db.h in /usr/include and the new db.h in + /usr/local/include. + +4.3BSD + If you are running a "virgin" version of 4.3BSD, you'll have + a very old resolver and be missing some header files. The + header files are simple -- create empty versions and everything + will work fine. For the resolver you should really port a new + version (4.8.3 or later) of the resolver; 4.9 is available on + gatekeeper.DEC.COM in pub/BSD/bind/4.9. If you are really + determined to continue to use your old, buggy version (or as + a shortcut to get sendmail working -- I'm sure you have the + best intentions to port a modern version of BIND), you can + copy ../contrib/oldbind.compat.c into src and add + oldbind.compat.o to OBJADD in the Makefile. + +A/UX + Date: Tue, 12 Oct 1993 18:28:28 -0400 (EDT) + From: "Eric C. Hagberg" + Subject: Fix for A/UX ndbm + + I guess this isn't really a sendmail bug, however, it is something + that A/UX users should be aware of when compiling sendmail 8.6. + + Apparently, the calls that sendmail is using to the ndbm routines + in A/UX 3.0.x contain calls to "broken" routines, in that the + aliases database will break when it gets "just a little big" + (sorry I don't have exact numbers here, but it broke somewhere + around 20-25 aliases for me.), making all aliases non-functional + after exceeding this point. + + What I did was to get the gnu-dbm-1.6 package, compile it, and + then re-compile sendmail with "-lgdbm", "-DNDBM", and using the + ndbm.h header file that comes with the gnu-package. This makes + things behave properly. + [NOTE: see comment above about GDBM] + + I suppose porting the New Berkeley DB package is another route, + however, I made a quick attempt at it, and found it difficult + (not easy at least); the gnu-dbm package "configured" and + compiled easily. + + [NOTE: Berkeley DB version 2.X runs on A/UX and can be used for + database maps.] + +SCO Unix + From: Thomas Essebier + Organisation: Stallion Technologies Pty Ltd. + + It will probably help those who are trying to configure sendmail 8.6.9 + to know that if they are on SCO, they had better set + OI-dnsrch + or they will core dump as soon as they try to use the resolver. + ie. although SCO has _res.dnsrch defined, and is kinda BIND 4.8.3, it + does not inititialise it, nor does it understand 'search' in + /etc/named.boot. + - sigh - + + According to SCO, the m4 which ships with UnixWare 2.1.2 is broken. + We recommend installing GNU m4 before attempting to build sendmail. + +DG/UX + Doug Anderson has successfully run + V8 on the DG/UX 5.4.2 and 5.4R3.x platforms under heavy usage. + Originally, the DG /bin/mail program wasn't compatible with + the V8 sendmail, since the DG /bin/mail requires the environment + variable "_FORCE_MAIL_LOCAL_=yes" be set. Version 8.7 now includes + this in the environment before invoking the local mailer. Some + have used procmail to avoid this problem in the past. It works + but some have experienced file locking problems with their DG/UX + ports of procmail. + +Apollo DomainOS + If you are compiling on Apollo, you will have to create an empty + file "unistd.h" (for DomainOS 10.3 and earlier) and create a file + "dirent.h" containing: + + #include + #define dirent direct + + (BuildTools/OS/DomainOS will attempt to do both of these for you.) + +HP-UX 8.00 + Date: Mon, 24 Jan 1994 13:25:45 +0200 + From: Kimmo Suominen + Subject: 8.6.5 w/ HP-UX 8.00 on s300 + + Just compiled and fought with sendmail 8.6.5 on a HP9000/360 (ie. a + series 300 machine) running HP-UX 8.00. + + I was getting segmentation fault when delivering to a local user. + With debugging I saw it was faulting when doing _free@libc... *sigh* + It seems the new implementation of malloc on s300 is buggy as of 8.0, + so I tried out the one in -lmalloc (malloc(3X)). With that it seems + to work just dandy. + + When linking, you will get the following error: + + ld: multiply defined symbol _freespace in file /usr/lib/libmalloc.a + + but you can just ignore it. You might want to add this info to the + README file for the future... + +Linux + Something broke between versions 0.99.13 and 0.99.14 of Linux: + the flock() system call gives errors. If you are running .14, + you must not use flock. You can do this with -DHASFLOCK=0. + + Around the inclusion of bind-4.9.3 & Linux libc-4.6.20, the + initialization of the _res structure changed. If /etc/hosts.conf + was configured as "hosts, bind" the resolver code could return + "Name server failure" errors. This is supposedly fixed in + later versions of libc (>= 4.6.29?), and later versions of + sendmail (> 8.6.10) try to work around the problem. + + Some older versions (< 4.6.20?) of the libc/include files conflict + with sendmail's version of cdefs.h. Deleting sendmail's version + on those systems should be non-harmful, and new versions don't care. + + Sendmail assumes that libc has snprintf, which has been true since + libc 4.7.0. If you are running an older version, you will need to + use -DHASSNPRINTF=0 in the Makefile. If may be able to use -lbsd + (which includes snprintf) instead of turning this off on versions + of libc between 4.4.4 and 4.7.0 (snprintf improves security, so + you want to use this if at all possible). + + NOTE ON LINUX & BIND: By default, the Makefile generated for Linux + includes header files in /usr/local/include and libraries in + /usr/local/lib. If you've installed BIND on your system, the header + files typically end up in the search path and you need to add + "-lresolv" to the LIBS line in your Makefile. Really old versions + may need to include "-l44bsd" as well (particularly if the link phase + complains about missing strcasecmp, strncasecmp or strpbrk). + Complaints about an undefined reference to `__dn_skipname' in + domain.o are a sure sign that you need to add -lresolv to LIBS. + Newer versions of Linux are basically threaded BIND, so you may or + may not see complaints if you accidentally mix BIND + headers/libraries with virginal libc. If you have BIND headers in + /usr/local/include (resolv.h, etc) you *should* be adding -lresolv + to LIBS. Data structures may change and you'd be asking for a + core dump. + +AIX 3.x + This version of sendmail does not support MB, MG, and MR resource + records, which are supported by AIX sendmail. + + Several people have reported that the IBM-supplied named returns + fairly random results -- the named should be replaced.

The 4.8.3 version + has been tested, but 4.9.x is out and should work. + + To make the load average code work correctly requires an + external routine, as the kernel does not maintain system + load averages, similar to AIX V3.1.x. A reverse port of the + older 1.05 'monitor' load average daemon code written by + Jussi Maki that will work on AIX V2 for the RT is available + by E-mail to Mark Whetzel . + That code depends on an external daemon to collect system + load information, and the external routine 'getloadavg', + that will return that information.

I ran + across these things when helping out some people who contacted me by + e-mail. + + 1) Use gcc 2.4.5 (or later?). Dell distributes gcc 2.1 with their + Issue 2.2 Unix.

This is because + the -ldbm distributed by Dell needs the bcopy, bcmp and bzero + functions. It is important that you specify both libraries in + the given order to be sure you only get the BSTRING functions + from the UCB library (and not the signal routines etc.). + + 3) Don't leave out "-lelf" even if compiling with "-lc -lucb". + The UCB library also has another copy of the nlist routines, + but we do want the ones from "-lelf". + + If anyone needs a compiled gcc 2.4.5 and/or a ported DB library, they + can use anonymous ftp to fetch them from lut.fi in the /kim directory. + They are copies of what I use on grendel.lut.fi, and offering them + does not imply that I would also support them.

Each mailing list with a separate owner uses - one open file descriptor (prior to 8.6.6 it was three open - file descriptors per list).

If you are using this version -of make, you may notice one or two places where the Makefile includes -"../../Makefile.inc". This file is not included with the sendmail -distribution because it's not part of sendmail. However, it is, -in toto: - - # @(#)Makefile.inc 8.1 (Berkeley) 6/6/93 - - BINDIR?= /usr/sbin - -The other directories should all have Makefile.dist files that work -on the old make, albeit without all the niceties included. - -You can also get a new Berkeley make from the Net2 release (available -on many public FTP archives). This version should also interpret old -Makefiles, so you could drop it in as your default make. - -For more details, see src/READ_ME. - - -+-----------------------+ -| DIRECTORY PERMISSIONS | -+-----------------------+ - -Sendmail often gets blamed for many problems that are actually the -result of other problems, such as overly permissive modes on directories. -For this reason, sendmail checks the modes on system directories and -files to determine if they have been trusted. For sendmail to run -without complaining, you MUST execute the following command: - - chmod go-w / /etc /usr /var /var/spool /var/spool/mqueue - -You will probably have to tweak this for your environment (for example, -some systems put the spool directory into /usr/spool instead of -/var/spool). As a general rule, after you have compiled sendmail, -run the command - - sendmail -v -bi - -to initialize the alias database. If it gives messages such as - - WARNING: writable directory /etc - WARNING: writable directory /usr/spool/mqueue - -then the directories listed have inappropriate write permissions and -should be secured to avoid various possible security attacks. - - -+---------------------+ -| DIRECTORY STRUCTURE | -+---------------------+ - -The structure of this directory tree is: - -cf Source for Berkeley configuration files. These are - different than what you've seen before. They are a - fairly dramatic rewrite, requiring the new sendmail - (since they use new features). -contrib Some contributed tools to help with sendmail. THESE - ARE NOT SUPPORTED by Berkeley -- contact the original - authors if you have problems. (This directory is not - on the 4.4BSD tape.) -doc Documentation. If you are getting source, read - op.me -- it's long, but worth it. -mail.local The source for the local delivery agent used for 4.4BSD. - THIS IS NOT PART OF SENDMAIL! and may not compile - everywhere, since it depends on some 4.4-isms. Warning: - it does mailbox locking differently than other systems. -mailstats Statistics printing program. It has the pathname of - sendmail.st compiled in, so if you've changed that, - beware. This isn't all that useful. -makemap A program that creates the keyed maps used by the $( ... $) - construct in sendmail. It is primitive but effective. - It takes a very simple input format, so you will probably - expect to preprocess must human-convenient formats - using sed scripts before this program will like them. - But it should be functionally complete. -praliases A program to print the DBM or NEWDB version of the - aliases file. -rmail Source for rmail(8).

Problem noted by Kari E. - Hurtta of the Finnish Meteorological Institute. - Ignore the debug resolver option unless using sendmail debug trace - option for resolver. Problem noted by Greg Nichols of Wind - River Systems. - If SingleThreadDelivery was enabled and the remote server returned a - protocol error on the DATA command, the connection would be - closed but the persistent host status file would not be - unlocked so other sendmail processes could not deliver to - that host. Problem noted by Peter Wemm of DIALix. - If queueing up a message due to an expensive mailer, don't increment - the number of delivery attempts or set the last delivery - attempt time so the message will be delivered on the next - queue run regardless of MinQueueAge. Problem noted by - Brian J. Coan of the Institute for Global Communications. - Authentication warnings of "Processed from queue _directory_" and - "Processed by _username_ with -C _filename_" would be logged - with the incorrect timestamp. Problem noted by Kari E. Hurtta - of the Finnish Meteorological Institute. - Use a better heuristic for detecting GDBM. - Log null connections on dropped connections. Problem noted by - Jon Lewis of Florida Digital Turnpike. - If class dbm maps are rebuilt, sendmail will now detect this and - reopen the map. Previously, they could give stale - results during a single message processing (but would - recover when the next message was received). Fix from - Joe Pruett of Q7 Enterprises. - Do not log failures such as "User unknown" on -bv or SMTP VRFY - requests. Problem noted by Kari E. Hurtta of the - Finnish Meteorological Institute. - Do not send a bounce message back to the sender regarding bad - recipients if the SMTP connection is dropped before the - message is accepted. Problem noted by Kari E. Hurtta of the - Finnish Meteorological Institute. - Use "localhost" instead of "[UNIX: localhost]" when connecting to - sendmail via a UNIX pipe. This will allow rulesets using - $&{client_name} to process without sending the string through - dequote. Problem noted by Alan Barrett of Internet Africa. - A combination of deferred delivery mode, a double bounce situation, - and the inability to save a bounce message to - /var/tmp/dead.letter would cause sendmail to send a bounce - to postmaster but not remove the offending envelope from the - queue causing it to create a new bounce message each time the - queue was run. Problem noted by Brad Doctor of Net Daemons - Associates. - Remove newlines from hostname information returned via DNS. There are - no known security implications of newlines in hostnames as - sendmail filters newlines in all vital areas; however, this - could cause confusing error messages. - Starting with sendmail 8.8.6, mail sent with the '-t' option would be - rejected if any of the specified addresses were bad. This - behavior was modified to only reject the bad addresses and not - the entire message. Problem noted by Jozsef Hollosi of - SuperNet, Inc. - Use Timeout.fileopen when delivering mail to a file.

Patch from Robert La Ferla. - When a NEWDB database map was rebuilt at the same time it was being - used by a queue run, the maps could be left locked for the - duration of the queue run, causing other processes to hang. - Problem noted by Kendall Libby of Shore.NET. - In some cases, NoRecipientAction=add-bcc was being ignored, so the - mail was passed on without any recipient header. This could - cause problems downstream. Problem noted by Xander Jansen - of SURFnet ExpertiseCentrum. - Give error when GDBM is used with sendmail. GDBM's locking and - linking of the .dir and .pag files interferes with sendmail's - locking and security checks. Problems noted by Fyodor - Yarochkin of the Kyrgyz Republic FreeNet. - Don't fsync qf files if SuperSafe option is not set. - Avoid extra calls to gethostbyname for addresses for which a - gethostbyaddr found no value. Also, ignore any returns - from gethostbyaddr that look like a dotted quad. - If PTR lookup fails when looking up an SMTP peer, don't tag it as - "may be forged", since at the network level we pretty much - have to assume that the information is good. - In some cases, errors during an SMTP session could leave files - open or locked. - Better handling of missing file descriptors (0, 1, 2) on startup. - Better handling of non-setuid binaries -- avoids certain obnoxious - errors during testing. - Errors in file locking of NEWDB maps had the incorrect file name - printed in the error message. - If the AllowBogusHELO option were set and an EHLO with a bad or - missing parameter were issued, the EHLO behaved like a HELO. - Load limiting never kicked in for incoming SMTP transactions if the - DeliverMode=background and any recipient was an alias or - had a .forward file. From Nik Conwell of Boston University. - On some non-Posix systems, the decision of whether chown(2) permits - file giveaway was undefined. From Tetsu Ushijima of the - Tokyo Institute of Technology. - Fix race condition that could cause the body of a message to be - lost (so only the header was delivered). This only occurs - on systems that do not use flock(2), and only when a queue - runner runs during a critical section in another message - delivery. Based on a patch from Steve Schweinhart of - Results Computing. - If a qf file was found in a mail queue directory that had a problem - (wrong ownership, bad format, etc.) and the file name was - exactly MAXQFNAME bytes long, then instead of being tried - once, it would be tried on every queue run. Problem noted - by Bryan Costales of Mercury Mail. - If the system supports an st_gen field in the status structure, - include it when reporting that a file has changed after open. - This adds a new compile flag, HAS_ST_GEN (0/1 option). - This out to be checked as well as reported, since it is - theoretically possible for an attacker to remove a file after - it is opened and replace it with another file that has the - same i-number, but some filesystems (notably AFS) return - garbage in this field, and hence always look like the file - has changed. As a practical matter this is not a security - problem, since the files can be neither hard nor soft links, - and on no filesystem (that I am aware of) is it possible to - have two files on the same filesystem with the same i-number - simultaneously. - Delete the root Makefile from the distribution -- it is only for - use internally, and does not work at customer sites. - Fix botch that caused the second MAIL FROM: command in a single - transaction to clear the entire transaction. Problem - noted by John Kennedy of Cal State University, Chico. - Work properly on machines that have _PATH_VARTMP defined without - a trailing slash. (And a pox on vendors that decide to - ignore the established conventions!) Problem noted by - Gregory Neil Shapiro of WPI. - Internal changes to make it easier to add another protocol family - (intended for IPv6). Patches are from John Kennedy of - CSU Chico. - In certain cases, 7->8 bit MIME decoding of Base64 text could leave - an extra space at the beginning of some lines. Problem - noted by Charles Karney of Princeton University; fix based - on a patch from Christophe Wolfhugel. - Portability: - Allow _PATH_VENDOR_CF to be set in Makefile for consistency - with the _Sendmail_ book, 2nd edition. Note that - the book is actually wrong: _PATH_SENDMAILCF should - be used instead. - AIX 3.x: Include . Patch from Gene Rackow - of Argonne National Laboratory. - OpenBSD from from Paul DuBois of the University of Wisconsin. - RISC/os 4.0 from Paul DuBois of the University of Wisconsin. - SunOS: Include to fix warning from util.c. From - James Aldridge of EUnet Ltd. - Solaris: Change STDIR (location of status file) to /etc/mail - in Makefiles. - Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from - Makefiles. Use NEWDB on Linux instead. - NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl - exists but behaves differently than other OSes. - Add SIOCGIFNUM_IS_BROKEN compile flag to get - around the problem. Problem noted by Tom Moore of - NCR Corp. - HP-UX 9.x: fix compile warnings for old select API. Problem - noted by Tom Smith of Digital Equipment Corp. - UnixWare 2.x: compile warnings on offsetof macro. Problem - noted by Tom Good of the Community Access Information - Resource Network - SCO 4.2: compile problems caused by a change in the type of - the "length" parameters passed to accept, getpeername, - getsockname, and getsockopt. Adds new compile flags - SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. Problem reported - by Tom Good of St. Vincent's North Richmond Community - Mental Health Center Residential Services. - AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. - Suggested by Brett Hogden of Rochester Gas & Electric - Corp. - Linux: avoid compile problem for versions of that - #define both setjmp and longjmp. Problem pointed out - by J.R. Oldroyd of TerraNet. - CONFIG: SCO UnixWare 2.1: Support for OSTYPE(sco-uw-2.1) - from Christopher Durham of SCO. - CONFIG: NEXTSTEP: define confCW_FILE to - /etc/sendmail/sendmail.cw to match the usual - configuration. Patch from Dennis Glatting of - PlainTalk. - CONFIG: MAILER(fax) called a program that hasn't existed for a long - time. Convert to use the HylaFAX 4.0 conventions.

This makes it possible to create a root - owned file in an arbitrary directory by inserting the symlink - into a writable directory after the initial lstat(2) check - determined that the file did not exist. The only verified - example of a system having these odd semantics for O_EXCL - and symbolic links was HP-UX prior to version 9.07. Most - systems do not have the problem, since a exclusive create - of a file disallows symbolic links. Systems that have been - verified to NOT have the problem include AIX 3.x, *BSD, - DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, - and Ultrix. This is a potential exposure on systems that - have this bug and which do not have a MAILER-DAEMON alias - pointing at a legitimate account, since this will cause old - mail to be dropped in /var/tmp/dead.letter. - SECURITY: Problems can occur on poorly managed systems, specifically, - if maps or alias files are in world writable directories. - If your system has alias maps in writable directories, it - is potentially possible for an attacker to replace the .db - (or .dir and .pag) files by symbolic links pointing at - another database; this can be used either to expose - information (e.g., by pointing an alias file at /etc/spwd.db - and probing for accounts), or as a denial-of-service attack - (by trashing the password database). The fix disallows - symbolic links entirely when rebuilding alias files or on - maps that are in writable directories, and always warns on - writable directories; 8.9 will probably consider writable - directories to be fatal errors. This does not represent an - exposure on systems that have alias files in unwritable - system directories. - SECURITY: disallow .forward or :include: files that are links (hard - or soft) if the parent directory (or any directory in the - path) is writable by anyone other than the owner. This is - similar to the previous case for user files. This change - should not affect most systems, but is necessary to prevent - an attacker who can write the directory from pointing such - files at other files that are readable only by the owner. - SECURITY: Tighten safechown rules: many systems will say that they - have a safe (restricted to root) chown even on files that - are mounted from another system that allows owners to give - away files. The new rules are very strict, trusting file - ownership only in those few cases where the system has - been verified to be at least as paranoid as necessary. - However, it is possible to relax the rules to partially - trust the ownership if the directory path is not world or - group writable. This might allow someone who has a legitimate - :include: file (referenced directly from /etc/aliases) to - become another non-root user if the :include: file is in a - non-writable directory on an NFS-mounted filesystem where - the local system says that giveaway is denied but it is - actually permitted. I believe this to be a very small set - of cases. If in doubt, do not point :include: aliases at - NFS-mounted filesystems. - SECURITY: When setting a numeric group id using the RunAsUser option - (e.g., "O RunAsUser=10:20", the group id would not be set. - Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha - group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. - The user id was still set properly. Problem noted by Uli - Pralle of the Technical University of Berlin. - Save the initial gid set for use when checking for if the - PrivacyOptions=restrictmailq option is set. Problem reported - by Wolfgang Ley of DFN-CERT. - Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a - failure on one message won't affect future messages to the - same host). - IP source route printing had an "off by one" error that would - affect any options that came after the route option. Patch - from Theo de Raadt. - The "Message is too large" error didn't successfully bounce the error - back to the sender. Problem reported by Stephen More of - PSI; patch from Gregory Neil Shapiro of WPI. - Change SMTP status code 553 to map into Extended code 5.1.0 (instead - of 5.1.3); it apparently gets used in multiple ways. - Suggested by John Myers of Portola Communications. - Fix possible extra null byte generated during collection if errors - occur at the beginning of the stream. Patch contributed by - Andrey A. Chernov and Gregory Neil Shapiro. - Code changes to avoid possible reentrant call of malloc/free within - a signal handler. Problem noted by John Beck of Sun - Microsystems. - Move map initialization to be earlier so that check_relay ruleset - will have the latest version of the map data. Problem noted - by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. - If there are fatal errors during the collection phase (e.g., message - too large) don't send the bogus message. - Avoid "cannot open xfAAA00000" messages when sending to aliases that - have errors and have owner- aliases. Problem noted by Michael - Barber of MTU; fix from Gregory Neil Shapiro of WPI. - Avoid null pointer dereference on illegal Boundary= parameters in - multipart/mixed Content-Type: header. Problem noted by - Richard Muirden of RMIT University. - Always print error messages during newaliases (-bi) even if the - ErrorMode is not set to "print". Fix from Gregory Neil - Shapiro. - Test mode could core dump if you did a /map lookup in an optional map - that could not be opened. Based on a fix from John Beck of - Sun Microsystems. - If DNS is misconfigured so that the last MX record tried points to - a host that does not have an A record, but other MX records - pointed to something reasonable, don't bounce the message - with a "host unknown" error. Note that this should really - be fixed in the zone file for the domain. Problem noted by - Joe Rhett of Navigist, Inc. - If a map fails (e.g., DNS times out) on all recipient addresses, mark - the message as having been tried; otherwise the next queue - run will not realize that this is a second attempt and will - retry immediately. Problem noted by Bryan Costales of - Mercury Mail. - If the clock is set backwards, and a MinQueueAge is set, no jobs - will be run until the later setting of the clock is reached. - "Problem" (I use the term loosely) noted by Eric Hagberg of - Morgan Stanley. - If the load average rises above the cutoff threshold (above which - sendmail will not process the queue at all) during a queue - run, abort the queue run immediately. Problem noted by - Bryan Costales of Mercury Mail. - The variable queue processing algorithm (based on the message size, - number of recipients, message precedence, and job age) was - non-functional -- either the entire queue was processed or - none of the queue was processed. The updated algorithm - does no queue run if a single recipient zero size job will - not be run. - If there is a fatal ("panic") message that will cause sendmail to - die immediately, never hold the error message for future - printing. - Force ErrorMode=print in -bt mode so that all errors are printed - regardless of the setting of the ErrorMode option in the - configuration file. Patch from Gregory Neil Shapiro. - New compile flag HASSTRERROR says that this OS has the strerror(3) - routine available in one of the libraries. Use it in conf.h. - The -m (match only) flag now works on host class maps. - If class hash or btree maps are rebuilt, sendmail will now detect - this and reopen the map. Previously, they could give - erroneous results during a single message processing - (but would recover when the next message was received). - Don't delete zero length queue files when doing queue runs until the - files are at least ten minutes old. This avoids a potential - race condition: the creator creates the qf file, getting back - a file descriptor. The queue runner locks it and deletes it - because it is zero length. The creator then writes the - descriptor that is now for a disconnected file, and the - job goes away. Based on a suggestion by Bryan Costales. - When determining the "validated" host name ($_ macro), do a forward - (A) DNS lookup on the result of the PTR lookup and compare - results. If they differ or if the PTR lookup fails, tag the - address as "may be forged". - Log null connections (i.e., hosts that connect but do not do any - substantive activity on the connection before disconnecting; - "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. - Always permit "writes" to /dev/null regardless of the link count. - This is safe because /dev/null is special cased, and no open - or write is ever actually attempted. Patch from Villy Kruse - of TwinCom. - If a message cannot be sent because of a 552 (exceeded storage - allocation) response to the MAIL FROM:<>, and a SIZE= parameter - was given, don't return the body in the bounce, since there - is a very good chance that the message will double-bounce. - Fix possible line truncation if a quoted-printable had an =00 escape - in the body. Problem noted by Charles Karney of the Princeton - Plasma Physics Laboratory. - Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. - Problem noted by Kari Hurtta of the Finnish Meteorological - Institute. - The MaxDaemonChildren option wasn't applying to queue runs as - documented. Note that this increases the potential denial - of service problems with this option: an attacker can - connect many times, and thereby lock out queue runs as well - as incoming connections. If you use this option, you should - run the "sendmail -bd" and "sendmail -q30m" jobs separately - to avoid this attack. Failure to limit noted by Matthew - Dillon of BEST Internet Communications. - Always give a message in newaliases if alias files cannot be - opened instead of failing silently. Suggested by Gregory - Neil Shapiro. This change makes the code match the O'Reilly - book (2nd edition). - Some older versions of the resolver could return with h_errno == -1 - if no name server could be reached, causing mail to bounce - instead of queueing. Treat this like TRY_AGAIN. Fix from - John Beck of SunSoft. - If a :include: file is owned by a user that does not have an entry - in the passwd file, sendmail could dereference a null pointer. - Problem noted by Satish Mynam of Sun Microsystems. - Take precautions to make sure that the SMTP protocol cannot get out - of sync if (for example) an alias file cannot be opened. - Fix a possible race condition that can cause a SIGALRM to come in - immediately after a SIGHUP, causing the new sendmail to die. - Avoid possible hang on SVr3 systems when doing child reaping. Patch - from Villy Kruse of TwinCom. - Ignore improperly formatted SMTP reply codes. Previously these were - partially processed, which could cause confusing error - returns. - Fix possible bogus pointer dereference when doing ldapx map lookups - on some architectures. - Portability: - A/UX: from Jim Jagielski of NASA/GSFC. - glibc: SOCK_STREAM was changed from a #define to an enum, - thus breaking #ifdef SOCK_STREAM. Only option seems - to be to assume SOCK_STREAM if __GNU_LIBRARY__ is - defined. Problem reported by A Sun of the University - of Washington. - Solaris: use SIOCGIFNUM to get the number of interfaces on - the system rather than guessing at compile time. - Patch contributed by John Beck of Sun Microsystems. - Intel Paragon: from Wendy Lin of Purdue University. - GNU Hurd: from Miles Bader of the GNU project. - RISC/os 4.50 from Harlan Stenn of PFCS Corporation. - ISC Unix: wait never returns if SIGCLD signals are blocked. - Unfortunately releasing them opens a race condition, - but there appears to be no fix for this. Patch from - Gregory Neil Shapiro. - BIND 8.1 for IPv6 compatibility from John Kennedy. - Solaris: a bug in strcasecmp caused characters with the - high order bit set to apparently randomly match - letters -- for example, $| (0233) matches "i" and "I". - Problem noted by John Gregson of the University of - Cambridge. - IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From - Kari Hurtta. - IRIX 6.x: Create Makefiles for systems that claim to be - IRIX64 but are 6.2 or higher (so use the regular - IRIX Makefile). - IRIX 6.x: Fix load average computation on 64 bit kernels. - Problem noted by Eric Hagberg of Morgan Stanley. - CONFIG: Some canonification was still done for UUCP-like addresses - even if FEATURE(nocanonify) was set. Problem pointed out by - Brian Candler. - CONFIG: In some cases UUCP mailers wouldn't properly recognize all - local names as local. Problem noted by Jeff Polk of BSDI; - fix provided by Gregory Neil Shapiro. - CONFIG: The "local:user" syntax entries in mailertables and other - "mailer:user" syntax locations returned an incorrect value - for the $h macro. Problem noted by Gregory Neil Shapiro. - CONFIG: Retain "+detail" information when forwarding mail to a - MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip - Guenther of Gustavus Adolphus College. - CONFIG: Make sure user+detail works for FEATURE(virtusertable); - rules are the same as for aliasing. Based on a patch from - Gregory Neil Shapiro. - CONFIG: Break up parsing rules into several pieces; this should - have no functional change in this release, but makes it - possible to have better anti-spam rulesets in the future. - CONFIG: Disallow double dots in host names to avoid having the - HostStatusDirectory store status under the wrong name. - In some cases this can be used as a denial-of-service attack. - Problem noted by Ron Jarrell of Virginia Tech, patch from - Gregory Neil Shapiro. - CONFIG: Don't use F=m (multiple recipients per invocation) for - MAILER(procmail), but do pass F=Pn9 (include Return-Path:, - don't include From_, and convert to 8-bit). Suggestions - from Kimmo Suominen and Roderick Schertler. - CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) where - being masqueraded as though FEATURE(masquerade_entire_domain) - was specified, even when it wasn't. - MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. - MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't - "slip in" a symbolic link between the lstat(2) call and the - exclusive open. This is only a problem on System V derived - systems that allow an exclusive create on files that are - symbolic links pointing nowhere. - MAIL.LOCAL: If the final mailbox close() failed, the user id was - not reset back to root, which on some systems would cause - later mailboxes to fail. Also, any partial message would - not be truncated, which could result in repeated deliveries. - Problem noted by Bruce Evans via Peter Wemm (FreeBSD - developers). - MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar - change to the sendmail map code was made in 8.8.3. Problem - noted by Gregory Neil Shapiro. - MAKEMAP: Give warnings on file problems such as map files that are - symbolic links; although makemap is not setuid root, it is - often run as root and hence has the potential for the same - sorts of problems as alias rebuilds. - MAKEMAP: Change compilation so that it will link properly on - NEXTSTEP. - CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. - Accept an optional list of arguments following the server - name for the ETRN arguments to use (instead of $=w). Other - miscellaneous bug fixes. From Christian von Roques via - John Beck of Sun Microsystems. - CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This - Perl script converts GECOS information in the /etc/passwd - file into aliases, allowing for faster access to full name - lookups; it is also clever about adding aliases (to root) - for system accounts. - NEW FILES: - src/safefile.c - cf/ostype/gnuhurd.m4 - cf/ostype/irix6.m4 - contrib/passwd-to-alias.pl - src/Makefiles/Makefile.IRIX64.6.1 - src/Makefiles/Makefile.IRIX64.6.x - RENAMED FILES: - src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x - src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 - -8.8.5/8.8.5 97/01/21 - SECURITY: Clear out group list during startup. Without this, sendmail - will continue to run with the group permissions of the caller, - even if RunAsUser is specified. - SECURITY: Make purgestat (-bH) be root-only. This is not in response - to any known attack, but it's best to be conservative. - Suggested by Peter Wemm of DIALix. - SECURITY: Fix buffer overrun problem in MIME code that has possible - security implications. Patch from Alex Garthwaite of the - University of Pennsylvania. - Use of a -f flag with a phrase attached (e.g., "-f 'Full Name '") - would truncate the address after "Full". Although the -f - syntax is incorrect (since it is in the envelope, it - shouldn't have comments and full names), the failure mode - was unnecessarily awful. - Fix a possible null pointer dereference when converting 8-bit data - to a 7-bit format. Problem noted by Jim Hutchins of - Sandia National Labs and David James of British Telecom. - Clear out stale state that affected F=9 on SMTP mailers in queue - runs. Although this really shouldn't be used (F=9 is for - final delivery only, and using it on an SMTP mailer makes - it possible for a message to be converted from 8->7->8->7 - bits several times), it shouldn't have failed with a syserr. - Problem noted by Eric Hagberg of Morgan Stanley. - _Really_ fix the multiple :maildrop code in the user database - module. Patch from Roy Mongiovi of Georgia Tech. - Let F lines in the configuration file actually read root-only - files if the configuration file is safe. Based on a - patch from Keith Reynolds of SCO. - ETRN followed by QUIT would hold the connection open until the queue - run completed. Problem noted by Truck Lewis of TDK - Semiconductor Corp. - It turns out that despite the documentation, the TCP wrappers library - does _not_ log rejected connections. Do the logging ourselves. - Problem noted by Fletcher Mattox of the University of Texas - at Austin. - If sendmail finds a qf file in its queue directory that is an unknown - version (e.g., when backing out to an old version), the - error is reported on every queue run. Change it to only - give the error once (and rename the qf => Qf). Patch from - William A. Gianopoulos of Raytheon Company. - Start a new session when doing background delivery; currently it - ignored signals but didn't start a new signal, that caused - some problems if a background process tried to send mail - under certain circumstances. Problem noted by Eric Hagberg - of Morgan Stanley; fix from Kari Hurtta. - Simplify test for skipping a queue run to just check if the current - load average is >= the queueing load average. Previously - the check factored in some other parameters that caused it - to essentially never skip the queue run. Patch from Bryan - Costales. - If the SMTP server is running in "nullserver" mode (that is, it is - rejecting all commands), start sleeping after MAXBADCOMMAND - (25) commands; this helps prevent a bad guy from putting - you into a tight loop as a denial-of-service attack. Based - on an e-mail conversation with Brad Knowles of AOL. - Slow down when too many "light weight" commands have been issued; - this helps prevent a class of denial-of-service attacks. - The current values and defaults are: - MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR - MAXHELOCOMMANDS 3 HELO, EHLO - MAXVRFYCOMMANDS 6 VRFY, EXPN - MAXETRNCOMMANDS 8 ETRN - These will probably be configurable in a future release. - On systems that have uid_t typedefed to be an unsigned short, programs - that had the F=S flag and no U= equate would be invoked with - the real uid set to 65535 rather than being left unchanged. - In some cases, NOTIFY=NEVER was not being honored. Problem noted - by Steve Hubert of the University of Washington, Seattle. - Mail that was Quoted-Printable encoded and had a soft line break on - the last line (i.e., an incomplete continuation) had the last - line dropped. Since this appears to be illegal it isn't - clear what to do with it, but flushing the last line seems - to be a better "fail soft" approach. Based on a patch from - Eric Hagberg. - If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a - bogus HELO command still causes the "Polite people say HELO - first" error message. Problem pointed out by Chris Thomas - of UCLA; patch from John Beck of SunSoft. - Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set - in PrivacyFlags. The -q shouldn't turn this command off. - Problem noted by Murray Kucherawy of Pacific Bell Internet; - based on a patch from Gregory Neil Shapiro of WPI. - Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) - in a DATA transaction to be sticky; these can occur because - a message is too large, and smaller messages should still go - through. Problem noted by Matt Dillon of Best Internet - Communications. - In some cases bounces were saved in /var/tmp/dead.letter even if they - had been successfully delivered to the envelope sender. - Problem noted Eric Hagberg of Morgan Stanley; solution from - Gregory Neil Shapiro of WPI. - Give better diagnostics on long alias lines. Based on code contributed - by Patrick Gosling of the University of Cambridge. - Increase the number of virtual interfaces that will be probed for - alternate names. Problem noted by Amy Rich of Shore.Net. - PORTABILITY: - UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from - Toshiaki Nomura of Fujitsu Limited. - SunOS with LDAP support: compile problems with struct timeval. - Patch from Nick Cuccia of TCSI Corporation. - SCO: from Keith Reynolds of SCO. - Solaris: kstat load average computation wasn't being used. - Fixes from Michael Ju. Tokarev of Telecom Service, JSC - (Moscow). - OpenBSD: from Jason Downs of teeny.org. - Altos System V: from Tim Rice. - Solaris 2.5: from Alan Perry of SunSoft. - Solaris 2.6: from John Beck of SunSoft. - Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli - of Pratt & Whitney . - CONFIG: It seems that I hadn't gotten the Received: line syntax - _just_right_ yet. Tweak it again. I'll omit the names - of the "contributors" (quantity two) in this one case. - As of now, NO MORE DISCUSSION about the syntax of the - Received: line. - CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), - it never inserts that class into the output file. Fix it - so it will honor EXPOSED_USER but will _not_ include root - automatically in this class. Problem noted by Ronan KERYELL - of Centre de Recherche en Informatique de l'École Nationale - Supérieure des Mines de Paris (CRI-ENSMP). - CONFIG: Clean up handling of "local:" syntax in relay specifications - such as LUSER_RELAY. This change permits the following - syntaxes: ``local:'' will send to the same user on the - local machine (e.g., in a mailertable entry for "host", - ``local:'' will cause an address addressed to user@host to - go to user on the local machone). ``local:user'' will send - to the named user on the local machine. ``local:user@host'' - is equivalent to ``local:user'' (the host is ignored). In - all cases, the original user@host is passed in $@ (i.e., the - detail information). Inspired by a report from Michael Fuhr. - CONFIG: Strip quotes from the first word of an "error:" host - indication. This lets you set (for example) the LUSER_RELAY - to be ``error:\"5.1.1\" Your Message Here''. Note the use - of the \" so that the resulting string is properly quoted. - Problem noted by Gregory Neil Shapiro of WPI. - OP.ME: documentation was inconsistent about whether sendmail did a - NOOP or a RSET to probe the connection (it does a RSET). - Inconsistency noted by Deeran Peethamparam. - OP.ME: insert additional blank pages so it will print properly on - a duplex printer. From Matthew Black of Cal State University, - Long Beach. - -8.8.4/8.8.4 96/12/02 - SECURITY: under some circumstances, an attacker could get additional - permissions by hard linking to files that were group - writable by the attacker. The solution is to disallow any - files that have hard links -- this will affect .forward, - :include:, and output files. Problem noted by Terry - Kyriacopoulos of Interlog Internet Services. As a - workaround, set UnsafeGroupWrites -- always a good idea. - SECURITY: the TryNullMXList (w) option should not be safe -- if it - is, it is possible to do a denial-of-service attack on - MX hosts that rely on the use of the null MX list. There - is no danger if you have this option turned off (the default). - Problem noted by Dan Bernstein. Also, make the DontInitGroups - unsafe. I know of no specific attack against this, although - a denial-of-service attack is probably possible, but in theory - you should not be able to safely tweak anything that affects - the permissions that are used when mail is delivered. - Purgestat could go into an infinite loop if one of the host status - directories somehow became empty. Problem noted by Roy - Mongiovi of Georgia Tech. - Processes got "lost" when counting children due to a race condition. - This caused "proc_list_probe: lost pid" messages to be logged. - Problem noted by several people. - On systems with System V SIGCLD child signal semantics (notably AIX - and HP-UX), mail transactions would print the message "451 - SMTP-MAIL: lost child: No child processes". Problem noted - by several people. - Miscellaneous compiler warnings on picky compilers (or when setting - gcc to high warning levels). From Tom Moore of NCR Corp. - SMTP protocol errors, and most errors on MAIL FROM: lines should - not be persistent between runs, since they are based on the - message rather than the host. Problem noted by Matt Dillon - of Best Internet Communications. - The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore - of NCR (a.k.a., AT&T Global Information Solutions). - Avoid the possibility of having a child daemon run to completion - (including closing the SMTP socket) before the parent has - had a chance to close the socket; this can cause the parent - to hang for a long time waiting for the socket to drain. - Patch from Don Lewis of TDK Semiconductor. - If the fork() failed in a queue run, the queue runners would not be - rescheduled (so queue runs would stop). Patch from Don Lewis. - Some error conditions in ETRN could cause output without an SMTP - status code. Problem noted by Don Lewis. - Multiple :maildrop addresses in the user database didn't work properly. - Patch from Roy Mongiovi of Georgia Tech. - Add ".db" automatically onto any user database spec that does not - already have it; this is for consistency with makemap, the - K line, and the documentation. Inconsistency pointed out - by Roy Mongiovi. - Allow sendmail to be properly called in nohup mode. Patch from - Kyle Jones of UUNET. - Change ETRN to ignore but still update host status files; previously - it would ignore them and not save the updated status, which - caused stale information to be maintained. Based on a patch - from Christopher Davis of Kapor Enterprises Inc. Also, have - ETRN ignore the MinQueueAge option. - Patch long term host status to recover more gracefully from an empty - host status file condition. Patch from NAKAMURA Motonori - of Kyoto University. - Several patches to signal handling code to fix potential race - conditions from Don Lewis. - Make it possible to compile with -DDAEMON=0 (previously it had some - compile errors). This turns DAEMON, QUEUE, and SMTP into - 0/1 compilation flags. Note that DAEMON is an obsolete - compile flag; use NETINET instead. Solution based on a - patch from Bryan Costales. - PORTABILITY FIXES: - AIX4: getpwnam() and getpwuid() do a sequential scan of the - /etc/security/passwd file when called as root. This - is very slow on some systems. To speed it up, use the - (undocumented) _getpw{nam,uid}_shadow() routines. - Patch from Chris Thomas of UCLA/OAC Systems Group. - SCO 5.x: include -lprot in the Makefile. Patch from Bill - Glicker of Burrelle's Information Service. - NEWS-OS 4.x: need a definition for MODE_T to compile. Patch - from Makoto MATSUSHITA of Osaka University. - SunOS 4.0.3: compile problems. Patches from Andrew Cole of - Leeds University and SASABE Tetsuro of the University - of Tokyo. - DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support - Services, Inc. - Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. - I believe this to have only been a problem if you - compiled with -DUSE_VENDOR_CF_PATH -- another reason - to stick with /etc/sendmail.cf as your One True Path. - Digital UNIX (OSF/1 on Alpha) load average computation from - Martin Laubach of the Technischen Universität Wien. - CONFIG: change default Received: line to be multiple lines rather - than one long one. By popular demand. - MAIL.LOCAL: warnings weren't being logged on some systems. Patch - from Jerome Berkman of U.C. Berkeley. - MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs - to take a very long time. Problem noted by Yoshiro YONEYA - of NTT Software Corporation. - CONTRIB: add etrn.pl, contributed by John Beck. - NEW FILES: - contrib/etrn.pl - -8.8.3/8.8.3 96/11/17 - SECURITY: it was possible to get a root shell by lying to sendmail - about argv[0] and then sending it a signal. Problem noted - by Leshka Zakharoff on the - best-of-security list. - Log sendmail binary version number in "Warning: .cf version level - (%d) exceeds program functionality (%d) message" -- this - should make it clearer to people that they are running - the wrong binary. - Fix a problem that occurs when you open an SMTP connection and then - do one or more ETRN commands followed by a MAIL command; at - the end of the DATA phase sendmail would incorrectly report - "451 SMTP-MAIL: lost child: No child processes". Problem - noted by Eric Bishop of Virginia Tech. - When doing text-based host canonification (typically /etc/hosts - lookup), a null host name would match any /etc/hosts entry - with space at the end of the line. Problem noted by Steve - Hubert of the University of Washington, Seattle. - 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. - Problem reported by Tom Smith of Digital Equipment Corp. - Increase the size of the DNS answer buffer -- the standard UDP packet - size PACKETSZ (512) is not sufficient for some nameserver - answers containing very many resource records. The resolver - may also switch to TCP and retry if it detects UDP packet - overflow. Also, allow for the fact that the resolver - routines res_query and res_search return the size of the - *un*truncated answer in case the supplied answer buffer it - not big enough to accommodate the entire answer. Patch from - Eric Wassenaar. - Improvements to MaxDaemonChildren code. If you think you have too - many children, probe the ones you have to verify that they - are still around. Suggested by Jared Mauch of CICnet, Inc. - Also, do this probe before growing the vector of children - pids; this previously caused the vector to grow indefinitely - due to a race condition. Problem reported by Kyle Jones of - UUNET. - On some architectures, (from the Berkeley DB library) defines - O_EXLOCK to zero; this fools the map compilation code into - thinking that it can avoid race conditions by locking on open. - Change it to check for O_EXLOCK non-zero. Problem noted by - Leif Erlingsson of Data Lege. - Always call res_init() on startup (if compiled in, of course) to - allow the sendmail.cf file to tweak resolver flags; without - it, flag tweaks in ResolverOptions are ignored. Patch from - Andrew Sun of Merrill Lynch. - Improvements to host status printing code. Suggested by Steve Hubert - of the University of Washington, Seattle. - Change MinQueueAge option processing to do the check for the job age - when reading the queue file, rather than at the end; this - avoids parsing the addresses, which can do DNS lookups. - Problem noted by John Beck of InReference, Inc. - When MIME was being 7->8 bit decoded, "From " lines weren't being - properly escaped. Problem noted by Peter Nilsson of the - University of Linkoping. - In some cases, sendmail would retain root permissions during queue - runs even if RunAsUser was set. Problem noted by Mark - Thomas of Mark G. Thomas Consulting. - If the F=l flag was set on an SMTP mailer to indicate that it is - actually local delivery, and NOTIFY=SUCCESS is specified in - the envelope, and the receiving SMTP server speaks DSN, then - the DSN would be both generated locally and propogated to the - other end. - The U= mailer field didn't correctly extract the group id if the - user id was numeric. Problem noted by Kenneth Herron of - MCI Telecommunications Communications. - If a message exceeded the fixed maximum size on input, the body of - the message was included in the bounce. Note that this did - not occur if it exceeded the maximum _output_ size. Problem - reported by Kyle Jones of UUNET. - PORTABILITY FIXES: - AIX4: 4.1 does't have a working setreuid(2); change the - AIX4 defines to use seteuid(2) instead, which - works on 4.1 as well as 4.2. Problem noted by - Håkan Lindholm of interAF, Sweden. - AIX4: use tzname[] vector to determine time zone name. - Patch from NAKAMURA Motonori of Kyoto University. - MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. - Contributed by Paul DuBois . - Solaris: kstat(3k) support for retrieving the load average. - This adds the LA_KSTAT definition for LA_TYPE. - The outline of the implementation was contributed - by Michael Tokarev of Telecom Service, JSC, Moscow. - HP-UX 10.0 gripes about the (perfectly legal!) forward - declaration of struct rusage at the top of conf.h; - change it to only be included if you are using gcc, - which is apparently the only compiler that requires - it in the first place. Problem noted by Jeff - Earickson of Colby College. - IRIX: don't default to using gcc. IRIX is a civilized - operating system that comes with a decent compiler - by default. Problem noted by Barry Bouwsma and - Kari Hurtta. - CONFIG: specify F=9 as default in FEATURE(local_procmail) for - consistency with other local mailers. Inconsistency - pointed out by Teddy Hogeborn . - CONFIG: if the "limited best mx" feature is used (to reduce DNS - overhead) as part of the bestmx_is_local feature, the - domain part was dropped from the name. Patch from Steve - Hubert of the University of Washington, Seattle. - CONFIG: catch addresses of the form "user@.dom.ain"; these could - end up being translated to the null host name, which would - return any entry in /etc/hosts that had a space at the end - of the line. Problem noted by Steve Hubert of the - University of Washington, Seattle. - CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer - Polytechnic Institute. - MAKEMAP: tweak hash and btree parameters for better performance. - Patch from Matt Dillon of Best Internet Communications. - NEW FILES: - src/Makefiles/Makefile.Linux.ppc - cf/ostype/aix4.m4 - cf/ostype/mklinux.m4 - -8.8.2/8.8.2 96/10/18 - SECURITY: fix a botch in the 7-bit MIME patch; the previous patch - changed the code but didn't fix the problem. - PORTABILITY FIXES: - Solaris: Don't use the system getusershell(3); it can - apparently corrupt the heap in some circumstances. - Problem found by Ken Pizzini of Spry, Inc. - OP.ME: document several mailer flags that were accidently omitted - from this document. These flags were F=d, F=j, F=R, and F=9. - CONFIG: no changes. - -8.8.1/8.8.1 96/10/17 - SECURITY: unset all environment variables that the resolver will - examine during queue runs and daemon mode. Problem noted - by Dan Bernstein of the University of Illinois at Chicago. - SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain - message could overflow a buffer if it was converted back - to 8 bits. This caused core dumps and has the potential - for a remote attack. Problem first noted by Gregory Shapiro - of WPI. - Avoid duplicate deliveries of error messages on systems that don't - have flock(2) support. Patch from Motonori Nakamura of - Kyoto University. - Ignore null FallBackMX (V) options. If this option is null (as - opposed to undefined) it can cause "null signature" syserrs - on illegal host names. - If a Base64 encoded text/plain message has no trailing newline in - the encoded text, conversion back to 8 bits will drop the - final line. Problem noted by Pierre David. - If running with a RunAsUser, sendmail would give bogus "cannot - setuid" (or seteuid, or setreuid) messages on some systems. - Problem pointed out by Jordan Mendelson of Web Services, Inc. - Always print error messages in -bv mode -- previously, -bv would - be absolutely silent on errors if the error mode was sent - to (say) mail-back. Problem noted by Kyle Jones of UUNET. - If -qI/R/S is set (or the ETRN command is used), ignore all long - term host status. This is necessary because it is common - to do this when you know a host has just come back up. - Disallow duplicate HELO/EHLO commands as required by RFC 1651 section - 4.2. Excessive permissiveness noted by Lee Flight of the - University of Leicester. - If a service (such as NIS) is specified as the last entry in the - service switch, but that service is not compiled in, sendmail - would return a temporary failure when an entry was not found - in the map. This caused the message to be queued instead of - bouncing immediately. Problem noted by Harry Edmon of the - University of Washington. - PORTABILITY FIXES: - Solaris 2.3 had compilation problems in conf.c. Several - people pointed this out. - NetBSD from Charles Hannum of MIT. - AIX4 improvements based on info from Steve Bauer of South - Dakota School of Mines & Technology. - CONFIG: ``error:code message'' syntax was broken in virtusertable. - Patch from Gil Kloepfer Jr. - CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set - using MASQUERADE_DOMAIN) were not masqueraded unless they - were also in $=w. Problem noted by Zoltan Basti of - Softec. - MAIL.LOCAL: patches to compile and link cleanly on AIX. Based - on a patch from Eric Hagberg of Morgan Stanley. - MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan - of Stanford via Robert La Ferla. - -8.8.0/8.8.0 96/09/26 - Under some circumstances, Bcc: headers would not be properly - deleted. Pointed out by Jonathan Kamens of OpenVision. - Log a warning if the sendmail daemon is invoked without a full - pathname, which prevents "kill -1" from working. I was - urged to put this in by Andrey A. Chernov of DEMOS (Russia). - Fix small buffer overflow. Since the data in this buffer was not - read externally, there was no security problem (and in fact - probably wouldn't really overflow on most compilers). Pointed - out by KIZU takashi of Osaka University. - Fix problem causing domain literals such as [1.2.3.4] to be ignored - if a FallbackMXHost was specified in the configuration file - -- all mail would be sent to the fallback even if the original - host was accessible. Pointed out by Munenari Hirayama of - NSC (Japan). - A message that didn't terminate with a newline would (sometimes) not - have the trailing "." added properly in the SMTP dialogue, - causing SMTP to hang. Patch from Per Hedeland of Ericsson. - The DaemonPortOptions suboption to bind to a particular address was - incorrect and nonfunctional due to a misunderstanding of the - semantics of binding on a passive socket. Patch from - NIIBE Yutaka of Mitsubishi Research Institute. - Increase the number of MX hosts for a single name to 100 to better - handle the truly huge service providers such as AOL, which - has 13 at the moment (and climbing). In order to avoid - trashing memory, the buffer for all names has only been - slightly increased in size, to 12.8K from 10.2K -- this means - that if a single name had 100 MX records, the average size - of those records could not exceed 128 bytes. Requested by - Brad Knowles of America On Line. - Restore use of IDENT returns where the OSTYPE field equals "OTHER". - Urged by Dan Bernstein of U.C. Berkeley. - Print q_statdate and q_specificity in address structure debugging - printout. - Expand MCI structure flag bits for debugging output. - Support IPv6-style domain literals, which can have colons between - square braces. - Log open file descriptors for the "cannot dup" messages in deliver(); - this is an attempt to track down a bug that one person seems - to be having (it may be a Solaris bug!). - DSN NOTIFY parameters were not properly propogated across queue runs; - this caused the NOTIFY info to sometimes be lost. Problem - pointed out by Claus Assmann of the - Christian-Albrechts-University of Kiel. - The statistics gathered in the sendmail.st file were too high; in - some cases failures (e.g., user unknown or temporary failure) - would count as a delivery as far as the statistics were - concerned. Problem noted by Tom Moore of AT&T GIS. - Systems that don't have flock() would not send split envelopes in - the initial run. Problem pointed out by Leonard Zubkoff of - Dandelion Digital. - Move buffer overflow checking -- these primarily involve distrusting - results that may come from NIS and DNS. - 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't - include and hence had the wrong pathnames for a few - things like /var/tmp. Reported by Matthew Green. - Conditions were reversed for the Priority: header, resulting in all - values being interpreted as non-urgent except for non-urgent, - which was interpreted as normal. Patch from Bryan Costales. - The -o (optional) flag was being ignored on hash and btree maps - since 8.7.2. Fix from Bryan Costales. - Content-Types listed in class "q" will always be encoded as - Quoted-Printable (or more accurately, will never be encoded - as base64). The class can have primary types (e.g., "text") - or full types (e.g., "text/plain"). Based on a suggestion by - Marius Olafsson of the University of Iceland. - Define ${envid} to be the original envelope id (from the ESMTP DSN - dialogue) so it can be passed to programs in mailers. - Define ${bodytype} to be the body type (from the -B flag or the - BODY= ESMTP parameter) so it can be passed to programs in - mailers. - Cause the VRFY command to return 252 instead of 250 unless the F=q - flag is set in the mailer descriptor. Suggested by John - Myers of CMU. - Implement ESMTP ETRN command to flush the queue for a specific host. - The command takes a host name; data for that host is - immediately (and asynchronously) flushed. Because this shares - the -qR implementation, other hosts may be attempted, but - there should be no security implications. Implementation - from John Beck of InReference, Inc. See RFC 1985 for details. - Add three new command line flags to pass in DSN parameters: -V envid - (equivalent to ENVID=envid on the MAIL command), -R ret - (equivalent to RET=ret on the MAIL command), and -Nnotify - (equivalent to NOTIFY=notify on the RCPT command). Note - that the -N flag applies to all recipients; there is no way - to specify per-address notifications on the command line, - nor is there an equivalent for the ORCPT= per-address - parameter. - Restore LogLevel option to be safe (it can only be increased); - apparently I went into paranoid mode between 8.6 and 8.7 - and made it unsafe. Pointed out by Dabe Murphy of the - University of Maryland. - New logging on log level 15: all SMTP traffic. Patches from - Andrew Gross of San Diego Supercomputer Center. - NetInfo property value searching code wasn't stopping when it found - a match. This was causing the wrong values to be found (and - had a memory leak). Found by Bastian Schleuter of TU-Berlin. - Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed - out by Bill Wisner of Electronics for Imaging that you can't - use the bracket address form for the MAIL_HUB macro, since - that causes the brackets to remain in the envelope recipient - address used for delivery. The simple fix (stripping off the - brackets in the config file) breaks the use of IP literal - addresses. This flag will solve that problem. - Add MustQuoteChars option. This is a list of characters that must - be quoted if they are found in the phrase part of an address - (that is, the full name part). The characters @,;:\()[] are - always in this list and cannot be removed. The default is - this list plus . and ' to match RFC 822. - Add AllowBogusHELO option; if set, sendmail will allow HELO commands - that do not include a host name for back compatibility with - some stupid SMTP clients. Setting this violates RFC 1123 - section 5.2.5. - Add MaxDaemonChildren option; if this is set, sendmail will start - rejecting connections if it has more than this many - outstanding children accepting mail. Note that you may - see more processes than this because of outgoing mail; this - is for incoming connections only. - Add ConnectionRateThrottle option. If set to a positive value, the - number of incoming SMTP connections that will be permitted - in a single second is limited to this number. Connections are - not refused during this time, just deferred. The intent is to - flatten out demand so that load average limiting can kick in. - It is less radical than MaxDaemonChildren, which will stop - accepting connections even if all the connections are idle - (e.g., due to connection caching). - Add Timeout.hoststatus option. This interval (defaulting to 30m) - specifies how long cached information about the state of a - host will be kept before they are considered stale and the - host is retried. If you are using persistent host status - (i.e., the HostStatusDirectory option is set) this will apply - between runs; otherwise, it applies only within a single queue - run and hence is useful only for hosts that have large queues - that take a very long time to run. - Add SingleLineFromHeader option. If set, From: headers are coerced - into being a single line even if they had newlines in them - when read. This is to get around a botch in Lotus Notes. - Text class maps were totally broken -- if you ever retrieved the last - item in a table it would be truncated. Problem noted by - Gregory Neil Shapiro of WPI. - Extend the lines printed by the mailq command (== the -bp flag) when - -v is given to 120 characters; this allows more information - to be displayed. Suggested by Gregory Neil Shapiro of WPI. - Allow macro definitions (`D' lines) with unquoted commas; previously - this was treated as end-of-input. Problem noted by Bryan - Costales. - The RET= envelope parameter (used for DSNs) wasn't properly written - to the queue file. Fix from John Hughes of Atlantic - Technologies, Inc. - Close /var/tmp/dead.letter after a successful write -- otherwise - if this happens in a queue run it can cause nasty delays. - Problem noted by Mark Horton of AT&T. - If userdb entries pointed to userdb entries, and there were multiple - values for a given key, the database cursor would get - trashed by the recursive call. Problem noted by Roy Mongiovi - of Georgia Tech. Fixed by reading all the values and creating - a comma-separated list; thus, the -v output will be somewhat - different for this case. - Fix buffer allocation problem with Hesiod-based userdb maps when - HES_GETMAILHOST is defined. Based on a patch by Betty Lee - of Stanford University. - When envelopes were split due to aliases with owner- aliases, and - there was some error on one of the lists, more than one of - the owners would get the message. Problem pointed out by - Roy Mongiovi of Georgia Tech. - Detect excessive recursion in macro expansions, e.g., $X defined - in terms of $Y which is defined in terms of $X. Problem - noted by Bryan Costales; patch from Eric Wassenaar. - When using F=U to get "ugly UUCP" From_ lines, a buffer could in - some cases get trashed causing bogus From_ lines. Fix from - Kyle Jones of UUNET. - When doing load average initialization, if the nlist call for avenrun - failed, the second and subsequent lookups wouldn't notice - that fact causing bogus load averages to be returned. Noted - by Casper Dik of Sun Holland. - Fix problem with incompatibility with some versions of inet_aton that - have changed the return value to unsigned, so a check for an - error return of -1 doesn't work. Use INADDR_NONE instead. - This could cause mail to addresses such as [foo.com] to bounce - or get dropped. Problem noted by Christophe Wolfhugel of the - Pasteur Institute. - DSNs were inconsistent if a failure occured during the DATA phase - rather than the RCPT phase: the Action: would be correct, but - the detailed status information would be wrong. Problem noted - by Bob Snyder of General Electric Company. - Add -U command line flag and the XUSR ESMTP extension, both indicating - that this is the initial MUA->MTA submission. The flag current - does nothing, but in future releases (when MUAs start using - these flags) it will probably turn on things like DNS - canonification. - Default end-of-line string (E= specification on mailer [M] lines) - to \r\n on SMTP mailers. Default remains \n on non-SMTP - mailers. - Change the internal definition for the *file* and *include* mailers - to have $u in the argument vectors so that they aren't - misinterpreted as SMTP mailers and thus use \r\n line - termination. This will affect anyone who has redefined - either of these in their configuration file. - Don't assume that IDENT servers close the connection after a query; - responses can be newline terminated. From Terry Kennedy of - St. Peter's College. - Avoid core dumps on erroneous configuration files that have - $#mailer with nothing following. From Bryan Costales. - Avoid null pointer dereference with high debug values in unlockqueue. - Fix from Randy Martin of Clemson University. - Fix possible buffer overrun when expanding very large macros. Fix - from Kyle Jones of UUNET. - After 25 EXPN or VRFY commands, start pausing for a second before - processing each one. This avoids a certain form of denial - of service attack. Potential attack pointed out by Bryan - Costales. - Allow new named (not numbered!) config file rules to do validity - checking on SMTP arguments: check_mail for MAIL commands and - check_rcpt for RCPT commands. These rulesets can do anything - they want; their result is ignored unless they resolve to the - $#error mailer, in which case the indicated message is printed - and the command is rejected. Similarly, the check_compat - ruleset is called before delivery with "from_addr $| to_addr" - (the $| is a meta-symbol used to separate the two addresses); - it can give a "this sender can't send to this recipient" - notification. Note that this patch allows $| to stand alone - in rulesets. - Define new macros ${client_name}, ${client_addr}, and ${client_port} - that have the name, IP address, and port number (respectively) - of the SMTP client (that is, the entity at the other end of - the connection. These can be used in (e.g.) check_rcpt to - verify that someone isn't trying to relay mail through your - host inappropriately. Be sure to use the deferred evaluation - form, for example $&{client_name}, to avoid having these bound - when sendmail reads the configuration file. - Add new config file rule check_relay to check the incoming connection - information. Like check_compat, it is passed the host name - and host address separated by $| and can reject connections - on that basis. - Allow IDA-style recursive function calls. Code contributed by Mark - Lovell and Paul Vixie. - Eliminate the "No ! in UUCP From address!" message" -- instead, create - a virtual UUCP address using either a domain address or the $k - macro. Based on code contributed by Mark Lovell and Paul - Vixie. - Add Stanford LDAP map. Requires special libraries that are not - included with sendmail. Contributed by Booker C. Bense - ; contact him for support. - See also the src/READ_ME file. - Allow -dANSI to turn on ANSI escape sequences in debug output; this - puts metasymbols (e.g., $+) in reverse video. Really useful - only for debugging deep bits of code where it is important to - distinguish between the single-character metasymbol $+ and the - two characters $, +. - Changed ruleset 89 (executed in dumpstate()) to a named ruleset, - debug_dumpstate. - Add new UnsafeGroupWrites option; if set, .forward and :include: - files that are group writable are considered "unsafe" -- that - is, programs and files referenced from such files are not - valid recipients. - Delete bogosity test for FallBackMX host; this prevented it to be a - name that was not in DNS or was a domain-literal. Problem - noted by Tom May. - Change the introduction to error messages to more clearly delineate - permanent from temporary failures; if both existed in a - single message it could be confusing. Suggested by John - Beck of InReference, Inc. - The IngoreDot (i) option didn't work for lines that were terminated - with CRLF. Problem noted by Ted Stockwell of Secure - Computing Corporation. - Add a heuristic to improve the handling of unbalanced `<' signs in - message headers. Problem reported by Matt Dillon of Best - Internet Communications. - Check for bogus characters in the 0200-0237 range; since these are - used internally, very strange errors can occur if those - characters appear in headers. Problem noted by Anders Gertz - of Lysator. - Implement 7 -> 8 bit MIME conversions. This only takes place if the - recipient mailer has the F=9 flag set, and only works on - text/plain body types. Code contributed by Marius Olafsson - of the University of Iceland. - Special case "postmaster" name so that it is always treated as lower - case in alias files regardless of configuration settings; - this prevents some potential problems where "Postmaster" or - "POSTMASTER" might not match "postmaster". In most cases - this change is a no-op. - The -o map flag was ignored for text maps. Problem noted by Bryan - Costales. - The -a map flag was ignored for dequote maps. Problem noted by - Bryan Costales. - Fix core dump when a lookup of a class "prog" map returns no - response. Patch from Bryan Costales. - Log instances where sendmail is deferring or rejecting connections - on LogLevel 14. Suggested by Kyle Jones of UUNET. - Include port number in process title for network daemons. Suggested - by Kyle Jones of UUNET. - Send ``double bounces'' (errors that occur when sending an error - message) to the address indicated in the DoubleBounceAddress - option (default: postmaster). Previously they were always - sent to postmaster. Suggested by Kyle Jones of UUNET. - Add new mode, -bD, that acts like -bd in all respects except that - it runs in foreground. This is useful for using with a - wrapper that "watches" system services. Suggested by Kyle - Jones of UUNET. - Fix botch in spacing around (parenthesized) comments in addresses - when the comment comes before the address. Patch from - Motonori Nakamura of Kyoto University. - Use the prefix "Postmaster notify" on the Subject: lines of messages - that are being bounced to postmaster, rather than "Returned - mail". This permits the person who is postmaster more - easily determine what messages are to their role as - postmaster versus bounces to mail they actually sent. Based - on a suggestion by Motonori Nakamura. - Add new value "time" for QueueSortOrder option; this causes the queue - to be sorted strictly by the time of submission. Note that - this can cause very bad behaviour over slow lines (because - large jobs will tend to delay small jobs) and on nodes with - heavy traffic (because old things in the queue for hosts that - are down delay processing of new jobs). Also, this does not - guarantee that jobs will be delivered in submission order - unless you also set DeliveryMode=queue. In general, it should - probably only be used on the command line, and only in - conjunction with -qRhost.domain. In fact, there are very few - cases where it should be used at all. Based on an - implementation by Motonori Nakamura. - If a map lookup in ruleset 5 returns tempfail, queue the message in - the same manner as other rulesets. Previously a temporary - failure in ruleset 5 was ignored. Patch from Booker Bense - of Stanford University. - Don't proceed to the next MX host if an SMTP MAIL command returns a - 5yz (permanent failure) code. The next MX host will still be - tried if the connection cannot be opened in the first place - or if the MAIL command returns a 4yz (temporary failure) code. - (It's hard to know what to do here, since neither RFC 974 nor - RFC 1123 specify when to proceed to the next MX host.) - Suggested by Jonathan Kamens of OpenVision, Inc. - Add new "-t" flag for map definitions (the "K" line in the .cf file). - This causes map lookups that get a temporary failure (e.g., - name server failure) to _not_ defer the delivery of the - message. This should only be used if your configuration file - is prepared to do something sensible in this case. Based on - an idea by Gregory Shapiro of WPI. - Fix problem finding network interface addresses. Patch from - Motonori Nakamura. - Don't reject qf entries that are not owned by your effective uid if - you are not running setuid; this makes management of certain - kinds of firewall setups difficult. Patch suggested by - Eamonn Coleman of Qualcomm. - Add persistent host status. This keeps the information normally - maintained within a single queue run in disk files that are - shared between sendmail instances. The HostStatusDirectory - is the directory in which the information is maintained. If - not set, persistent host status is turned off. If not a full - pathname, it is relative to the queue directory. A common - value is ".hoststat". - There are also two new operation modes: - * -bh prints the status of hosts that have had recent - connections. - * -bH purges the host statuses. No attempt is made to save - recent status information. - This feature was originally written by Paul Vixie of Vixie - Enterprises for KJS and adapted for V8 by Mark Lovell of - Bigrock Consulting. Paul's funding of Mark and Mark's patience - with my insistence that things fit cleanly into the V8 - framework is gratefully appreciated. - New SingleThreadDelivery option (requires HostStatusDirectory to - operate). Avoids letting two sendmails on the local machine - open connections to the same remote host at the same time. - This reduces load on the other machine, but can cause mail to - be delayed (for example, if one sendmail is delivering a huge - message, other sendmails won't be able to send even small - messages). Also, it requires another file descriptor (for the - lock file) per connection, so you may have to reduce - ConnectionCacheSize to avoid running out of per-process - file descriptors. Based on the persistent host status code - contributed by Paul Vixie and Mark Lovell. - Allow sending to non-simple files (e.g., /dev/null) even if the - SafeFileEnvironment option is set. Problem noted by Bryan - Costales. - The -qR flag mistakenly matched flags in the "R" line of the queue - file. Problem noted by Bryan Costales. - If a job was aborted using the interrupt signal (e.g., control-C from - the keyboard), on some occasions an empty df file would be - left around; these would collect in the queue directory. - Problem noted by Bryan Costales. - Change the makesendmail script to enhance the search for Makefiles - based on release number. For example, on SunOS 5.5.1, it will - search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then - Makefile.SunOS.5.x (in addition to the other rules, e.g., - adding $arch). Problem noted by Jason Mastaler of Atlanta - Webmasters. - When creating maps using "newaliases", always map the keys to lower - case when creating the map unless the -f flag is specified on - the map itself. Previously this was done based on the F=u - flag in the local mailer, which meant you could create aliases - that you could never access. Problem noted by Bob Wu of DEC. - When a job was read from the queue, the bits causing notification on - failure or delay were always set. This caused those - notifications to be sent even if NOTIFY=NEVER had been - specified. Problem noted by Steve Hubert of the University - of Washington, Seattle. - Add new configurable routine validate_connection (in conf.c). This - lets you decide if you are willing to accept traffic from - this host. If it returns FALSE, all SMTP commands will return - "550 Access denied". -DTCPWRAPPERS will include support for - TCP wrappers; you will need to add -lwrap to the link line. - (See src/READ_ME for details.) - Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster - bounces. Some people seemed to think that this could be - confusing (even though it is true). Suggested by Motonori - Nakamura. - Add new RunAsUser option; this causes sendmail to do a setuid to that - user early in processing to avoid potential security problems. - However, this means that all .forward and :include: files must - be readable by that user, and all files to be written must be - writable by that user and all programs will be executed by that - user. It is also incompatible with the SafeFileEnvironment - option. In other words, it may not actually add much to - security. However, it should be useful on firewalls and other - places where users don't have accounts and the aliases file is - well constrained. - Add Timeout.iconnect. This is like Timeout.connect except it is used - only on the first attempt to delivery to an address. It could - be set to be lower than Timeout.connect on the principle that - the mail should go through quickly to responsive hosts; less - responsive hosts get to wait for the next queue run. - Fix a problem on Solaris that occassionally causes programs - (such as vacation) to hang with their standard input connected - to a UDP port. It also created some signal handling problems. - The problems turned out to be an interaction between vfork(2) - and some of the libraries, particularly NIS/NIS+. I am - indebted to Tor Egge for this fix. - Change user class map to do the same matching that actual delivery - will do instead of just a /etc/passwd lookup. This adds - fuzzy matching to the user map. Patch from Dan Oscarsson. - The Timeout.* options are not safe -- they can be used to create a - denial-of-service attack. Problem noted by Christophe - Wolfhugel. - Don't send PostMasterCopy messages in the event of a "delayed" - notification. Suggested by Barry Bouwsma. - Don't advertise "VERB" ESMTP extension if the "noexpn" privacy - option is set, since this disables VERB mode. Suggested - by John Hawkinson of MIT. - Complain if the QueueDirectory (Q) option is not set. Problem noted - by Motonori Nakamura of Kyoto University. - Only queue messages on transient .forward open failures if there - were no successful opens. The previous behaviour caused it - to queue even if a "fall back" .forward was found. Problem - noted by Ann-Kian Yeo of the Dept. of Information Systems - and Computer Science (DISCS), NUS, Singapore. - Don't do 8->7 bit conversions when bouncing a MIME message that - is bouncing because of a MIME error during 8->7 bit conversion; - the encapsulated message will bounce again, causing a loop. - Problem noted by Steve Hubert of the University of Washington. - Create xf (transcript) files using the TempFileMode option value - instead of 0644. Suggested by Ann-Kian Yeo of the - National University of Singapore. - Print errors if setgid/setuid/etc. fail during delivery. This helps - detect cases where DefaultUid is set to something that the - system can't cope with. - PORTABILITY FIXES: - Support for AIX/RS 2.2.1 from Mark Whetzel of Western - Atlas International. - Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell - . - On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only - work on the first recipient of a message due to a - bug in the getpwent family. If this is something you - use, you can define DEC_OSF_BROKEN_GETPWENT=1 for a - workaround. From Maximum Entropy of Sanford C. - Bernstein and Associates. - FreeBSD 1.1.5.1 uname -r returns a string containing - parentheses, which breaks makesendmail. Reported - by Piero Serini . - Sequent DYNIX/ptx 4.0.2 patches from Jack Woolley of - Systems and Computer Technology Corporation. - Solaris 2.x: omit the UUCP grade parameter (-g flag) because - it is system-dependent. Problem noted by J.J. Bailey - of Bailey Computer Consulting. - Pyramid NILE running DC/OSx support from Earle F. Ake of - Hassler Communication Systems Technology, Inc. - HP-UX 10.x compile glitches, reported by Anne Brink of the - U.S. Army and James Byrne of Harte & Lyne Limited. - NetBSD from Matthew Green of the NetBSD crew. - SCO 5.x from Keith Reynolds of SCO. - IRIX 6.2 from Robert Tarrall of the University of - Colorado and Kari Hurtta of the Finnish Meteorological - Institute. - UXP/DS (Fujitsu/ICL DS/90 series) support from Diego R. - Lopez, CICA (Seville). - NCR SVR4 MP-RAS 3.x support from Tom Moore of NCR. - PTX 3.2.0 from Kenneth Stailey of the US Department of Labor - Employment Standards Administration. - Altos System V (5.3.1) from Tim Rice of Multitalents. - Concurrent Systems Corporation Maxion from Donald R.

Nathanson of NeXT. - Solaris 2.5 configuration fixes for mail.local by Jim Davis - of the University of Arizona. - Solaris 2.5 has a working setreuid. Noted by David Linn of - Vanderbilt University. - Solaris changes for praliases, makemap, mailstats, and smrsh. - Previously you had to add -DSOLARIS in Makefile.dist; - this auto-detects. Based on a patch from Randall - Winchester of the University of Maryland. - CONFIG: add generic-nextstep3.3.mc file. Contributed by - Robert La Ferla of Hot Software. - CONFIG: allow mailertables to resolve to ``error:code message'' - (where "code" is an exit status) on domains (previously - worked only on hosts). Patch from Cor Bosman of Xs4all - Foundation. - CONFIG: hooks for IPv6-style domain literals. - CONFIG: predefine ALIAS_FILE and change the prototype file so that - if it is undefined the AliasFile option is never set; this - should be transparent for most everyone. Suggested by John - Myers of CMU. - CONFIG: add FEATURE(limited_masquerade). Without this feature, any - domain listed in $=w is masqueraded. With it, only those - domains listed in a MASQUERADE_DOMAIN macro are masqueraded. - CONFIG: add FEATURE(masquerade_entire_domain). This causes - masquerading specified by MASQUERADE_DOMAIN to apply to all - hosts under those domains as well as the domain headers - themselves. For example, if a configuration had - MASQUERADE_DOMAIN(foo.com), then without this feature only - foo.com would be masqueraded; with it, *.foo.com would be - masqueraded as well. Based on an implementation by Richard - (Pug) Bainter of U. Texas. - CONFIG: add FEATURE(genericstable) to do a more general rewriting of - outgoing addresses. Defaults to ``hash -o /etc/genericstable''. - Keys are user names; values are outgoing mail addresses. Yes, - this does overlap with the user database, and figuring out - just when to use which one may be tricky. Based on code - contributed by Richard (Pug) Bainter of U. Texas with updates - from Per Hedeland of Ericsson. - CONFIG: add FEATURE(virtusertable) to do generalized rewriting of - incoming addresses. Defaults to ``hash -o /etc/virtusertable''. - Keys are either fully qualified addresses or just the host - part (with the @ sign). For example, a table containing: - info@foo.com foo-info - info@bar.com bar-info - @baz.org jane@elsewhere.net - would send all mail destined for info@foo.com to foo-info - (which is presumably an alias), mail addressed to info@bar.com - to bar-info, and anything addressed to anyone at baz.org will - be sent to jane@elsewhere.net. The names foo.com, bar.com, - and baz.org must all be in $=w. Based on discussions with - a great many people. - CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. - Suggested by Richard Bainter. - CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the - "fax" mailer. - CONFIG: allow mailertable entries to resolve to local:user; this - passes the original user@host in to procmail-style local - mailers as the "detail" information to allow them to do - additional clever processing. From Joe Pruett of - Teleport Corporation. Delivery to the original user can - be done by specifying "local:" (with nothing after the colon). - CONFIG: allow any context that takes "mailer:domain" to also take - "mailer:user@domain" to force mailing to the given user; - "local:user" can also be used to do local delivery. This - applies on *_RELAY and in the mailertable entries. Based - on a suggestion by Ribert Kiessling of Easynet. - CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that - limits the possible domains; this reduces the number of DNS - lookups required to support this feature. For example, - FEATURE(bestmx_is_local, my.site.com) limits the lookups - to domains under my.site.com. Code contributed by Anthony - Thyssen . - CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, - such as the check_rcpt ruleset. Suggested by Gregory Shapiro - of WPI. - CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the - event you have to define local mailers. Suggested by - Gregory Shapiro of WPI. - CONFIG: fix cases where a three- (or more-) stage route-addr could - be misinterpreted as a list:...; syntax. Based on a patch by - Vlado Potisk . - CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is - remotely connected. The address host!user was being - converted to host!user@thishost instead of host!user@uurelay. - Problem noted by William Gianopoulos of Raytheon Company. - CONFIG: add confTO_ICONNECT to set Timeout.iconnect. - CONFIG: change FEATURE(redirect) message from "User not local" to - "User has moved"; the former wording was confusing if the - new address is still on the local host. Based on a suggestion - by Andreas Luik. - CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). - However, the class is not pre-initialized to contain root. - Suggested by Gregory Neil Shapiro. - CONTRIB: Remove XLA code at the request of the author, Christophe - Wolfhugel. - CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. - MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note - well: this produces a slightly different mailbox format (no - Content-Length: headers), file ownerships and modes are - different (not owned by group mail; mode 600 instead of 660), - and the local mailer flags will have to be tweaked (make them - match bsd4.4) in order to use this mailer. Patches from Paul - Hammann of the Missouri Research and Education Network. - MAIL.LOCAL: in some cases it could return EX_OK even though there - was a delivery error, such as if the ownership on the file - was wrong or the mode changed between the initial stat and - the open. Problem reported by William Colburn of the New - Mexico Institute of Mining and Technology. - MAILSTATS: handle zero length files more reliably. Patch from Bryan - Costales. - MAILSTATS: add man page contributed by Keith Bostic of BSDI. - MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't - honored.

This is not exploitable from off-site. - Workarounds include using a unique user for the DefaultUser - (old u & g options) and using smrsh as the local shell. - SECURITY: fix some buffer overruns; in at least one case this allows - a local user to get root. This is not known to be exploitable - from off-site. The workaround is to disable chfn(1) commands. - -8.7.5/8.7.3 96/03/04 - Fix glitch in 8.7.4 when putting certain internal lines; this can - in some case cause connections to hang or messages to have - extra spaces in odd places. Patch from Eric Wassenaar; - reports from Eric Hall of Chiron Corporation, Stephen - Hansen of Stanford University, Dean Gaudet of HotWired, - and others. - -8.7.4/8.7.3 96/02/18 - SECURITY: In some cases it was still possible for an attacker to - insert newlines into a queue file, thus allowing access to - any user (except root). - CONFIG: no changes -- it is not a bug that the configuration - version number is unchanged. - -8.7.3/8.7.3 95/12/03 - Fix botch in name server timeout in RCPT code; this problem caused - two responses in SMTP, which breaks things horribly. Fix - from Gregory Neil Shapiro of WPI. - Verify that L= value on M lines cannot be negative, which could cause - negative array subscripting. Not a security problem since - this has to be in the config file, but it could have caused - core dumps. Pointed out by Bryan Costales. - Fix -d21 debug output for long macro names. Pointed out by Bryan - Costales. - PORTABILITY FIXES: - SCO doesn't have ftruncate. From Bill Aten of Computerizers. - IBM's version of arpa/nameser.h defaults to the wrong byte - order. Tweak it to work properly. Based on fixes - from Fletcher Mattox of UTexas and Betty Lee of - Stanford University. - CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. - Deficiency pointed out by Bryan Costales of ICSI. - -8.7.2/8.7.2 95/11/19 - REALLY fix the backslash escapes in SmtpGreetingMessage, - OperatorChars, and UnixFromLine options. They were not - properly repaired in 8.7.1. - Completely delete the Bcc: header if and only if there are other - valid recipient headers (To:, Cc: or Apparently-To:, the - last being a historic botch, of course). If Bcc: is the - only recipient header in the message, it's value is tossed, - but the header name is kept. The old behaviour (always keep - the header name and toss the value) allowed primary recipients - to see that a Bcc: went to _someone_. - Include queue id on ``Authentication-Warning: : set - sender to using -f'' syslog messages. Suggested - by Kari Hurtta. - If a sequence or switch map lookup entry gets a tempfail but then - continues on to another map type, but the name is not found, - return a temporary failure from the sequence or switch map. - For example, if hosts search ``dns files'' and DNS fails - with a tempfail, the hosts map will go on and search files, - but if it fails the whole thing should be a tempfail, not - a permanent (host unknown) failure, even though that is the - failure in the hosts.files map. This error caused hard - bounces when it should have requeued. - Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo - owned by bar mode 700 and inbox being setuid bar stopped - working properly due to excessive paranoia. Pointed out by - John Hawkinson of Panix. - An SMTP RCPT command referencing a host that gave a nameserver - timeout would return a 451 command (8.6 accepted it and - queued it locally). Revert to the 8.6 behaviour in order - to simplify queue management for clustered systems. Suggested - by Gregory Neil Shapiro of WPI. The same problem could break - MH, which assumes that the SMTP session will succeed (tsk, tsk - -- mail gets lost!); this was pointed out by Stuart Pook of - Infobiogen. - Fix possible buffer overflow in munchstring(). This was not a security - problem because you couldn't specify any argument to this - without first giving up root privileges, but it is still a - good idea to avoid future problems. Problem noted by John - Hawkinson and Sam Hartman of MIT. - ``452 Out of disk space for temp file'' messages weren't being - printed. Fix from David Perlin of Nanosoft. - Don't advertise the ESMTP DSN extension if the SendMIMEErrors option - is not set, since this is required to get the actual DSNs - created. Problem pointed out by John Gardiner Myers of CMU. - Log permission problems that cause .forward and :include: files to - be untrusted or ignored on log level 12 and higher. Suggestted - by Randy Martin of Clemson University. - Allow user ids in U= clauses of M lines to have hyphens and - underscores. - Fix overcounting of recipients -- only happened when sending to an - alias. Pointed out by Mark Andrews of SGI and Jack Woolley - of Systems and Computer Technology Corporation. - If a message is sent to an address that fails, the error message that - is returned could show some extraneous "success" information - included even if the user did not request success notification, - which was confusing. Pointed out by Allan Johannesen of WPI. - Config files that had no AliasFile definition were defaulting to - using /etc/aliases; this caused problems with nullclient - configurations. Change it back to the 8.6 semantics of - having no local alias file unless it is declared. Problem - noted by Charles Karney of Princeton University. - Fix compile problem if NOTUNIX is defined. Pointed out by Bryan - Costales of ICSI. - Map lookups of class "userdb" maps were always case sensitive; they - should be controlled by the -f flag like other maps. Pointed - out by Bjart Kvarme . - Fix problem that caused some addresses to be passed through ruleset 5 - even when they were tagged as "sticky" by prefixing the - address with an "@". Patch from Thomas Dwyer III of Michigan - Technological University. - When converting a message to Quoted-Printable, prevent any lines with - dots alone on a line by themselves. This is because of the - preponderence of broken mailers that still get this wrong. - Code contributed by Per Hedeland of Ericsson. - Fix F{macro}/file construct -- it previously did nothing. Pointed - out by Bjart Kvarme of USIT/UiO (Norway). - Announce whether a cached connection is SMTP or ESMTP (in -v mode). - Requested by Allan Johannesen. - Delete check for text format of alias files -- it should be legal - to have the database format of the alias files without the - text version. Problem pointed out by Joe Rhett of Navigist, - Inc. - If "Ot" was specified with no value, the TZ variable was not properly - imported from the environment. Pointed out by Frank Crawford - . - Some architectures core dumped on "program" maps that didn't have - extra arguments. Patch from Booker C. Bense of Stanford - University. - Queue run processes would re-spawn daemons when given a SIGHUP; only - the parent should do this. Fix from Brian Coan of the - Association for Progressive Communications. - If MinQueueAge was set and a message was considered but not run - during a queue run and the Timeout.queuereturn interval was - reached, a "timed out" error message would be returned that - didn't include the failed address (and claimed to be a warning - even though it was fatal). The fix is to not return such - messages until they are actually tried, i.e., in the next - MinQueueAge interval. Problem noted by Rein Tollevik of - SINTEF RUNIT, Oslo. - Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions - that have the hes_getmailhost() routine. DEC Hesiod - distributions do not have this routine. Based on a patch - from Betty Lee of Stanford University. - Extensive cleanups to map open code to handle a locking race condition - in ndbm, hash, and btree format database files on some (most - non-4.4-BSD based) OS architectures. This should solve the - occassional "user unknown" problem during alias rebuilds that - has plagued me for quite some time. Based on a patch from - Thomas Dwyer III of Michigan Technological University. - PORTABILITY FIXES: - Solaris: Change location of newaliases and mailq from - /usr/ucb to /usr/bin to match Sun settings. From - James B. Davis of TCI. - DomainOS: Makefile.DomainOS doesn't require -ldbm. From - Don Lewis of Silicon Systems. - HP-UX 10: rename Makefile.HP-UX.10 => Makefile.HP-UX.10.x - so that the makesendmail script will find it. Pointed - out by Richard Allen of the University of Iceland. - Also, use -Aa -D_HPUX_SOURCE instead of -Ae, which - isn't supported on all compilers. - UXPDS: compilation fixes from Diego R. Lopez. - CONFIG: FAX mailer wasn't setting .FAX as a pseudo-domain unless - you also had a FAX_RELAY.

Based on - a bug report submitted by Paul Hoffman of Proper Publishing. - CONFIG: Make OSTYPE files consistently not override settings that - have already been set. Previously it worked differently - for different files. - CONFIG: Change relay mailer to do masquerading like 8.6 did. My take - is that this is wrong, but the change was causing problems - for some people. From Per Hedeland of Ericsson. - CONTRIB: bitdomain.c patch from John Gardiner Myers ; - portability changes for Posix environments (no functional - changes). - -8.7.1/8.7.1 95/10/01 - Old macros that have become options (SmtpGreetingMessage, - OperatorChars, and UnixFromLine) didn't allow backslash - escapes in the options, where they previously had. Bug - pointed out by John Hawkinson of MIT. - Fix strange case of an executable called by a program map that - returns a value but also a non-zero exit status; this - would give contradictory results in the higher level; in - particular, the default clause in the map lookup would be - ignored. Change to ignore the value if the program returns - non-zero exit status. From Tom Moore of AT&T GIS. - Shorten parameters passed to syslog() in some contexts to avoid a - bug in many vendors' implementations of that routine. Although - this isn't really a bug in sendmail per se, and my solution - has to assume that syslog() has at least a 1K buffer size - internally (I know some vendors have shortened this - dramatically -- they're on their own), sendmail is a popular - target. Also, limit the size of %s arguments in sprintf. - These both have possible security implications. Solutions - suggested by Casper Dik of Sun's Network Security Group - (Holland), Mark Seiden, and others. - Fix a problem that might cause a non-standard -B (body type) - parameter to be passed to the next server with undefined - results. This could have security implications. - If a filesystem was at > 100% utilization, the freediskspace() - routine incorrectly returned an error rather than zero. - Problem noted by G. Paul Ziemba of Alantec. - Change MX sort order so that local hostnames (those in $=w) always - sort first within a given preference. This forces the bestmx - map to always return the local host first, if it is included - in the list of highest priority MX records. From K. Robert - Elz. - Avoid some possible null pointer dereferences. Fixes from Randy - Martin - When sendmail starts up on systems that have no fully qualified - domain name (FQDN) anywhere in the first matching host map - (e.g., /etc/hosts if the hosts service searches "files dns"), - sendmail would sleep to try to find a FQDN, which it really - really needs. This has been changed to fall through to the - next map type if it can't find a FQDN -- i.e., if the hosts - file doesn't have a FQDN, it will try dns even though the - short name was found in /etc/hosts. This is probably a crock, - but many people have hosts files without FQDNs. Remember: - domain names are your friends. - Log a high-priority message if you can't find your FQDN during startup. - Suggested by Simon Barnes of Schlumberger Limited. - When using Hesiod, initialize it early to improve error reporting. - Patch from Don Lewis of Silicon Systems, Inc. - Apparently at least some versions of Linux have a 90 !minute! TCP - connection timeout in the kernel. Add a new "connect" timeout - to limit this time. Defaults to zero (use whatever the - kernel provides). Based on code contributed by J.R. Oldroyd - of TerraNet. - Under some circumstances, a failed message would not be properly - removed from the queue, causing tons of bogus error messages. - (This fix eliminates the problematic EF_KEEPQUEUE flag.) - Problem noted by Allan E Johannesen and Gregory Neil Shapiro - of WPI. - PORTABILITY FIXES: - On IRIX 5.x, there was an inconsistency in the setting - of sendmail.st location. Change the Makefile to - install it in /var/sendmail.st to match the OSTYPE - file and SGI standards. From Andre - . - Support for Fujitsu/ICL UXP/DS (For the DS/90 Series) - from Diego R. Lopez . - Linux compilation patches from J.R. Oldroyd of TerraNet, Inc. - LUNA 2 Mach patches from Motonori Nakamura. - SunOS Makefile was including -ldbm, which is for the old - dbm library. The ndbm library is part of libc. - CONFIG: avoid bouncing ``user@host.'' (note trailing dot) with - ``local configuration error'' in nullclient configuration. - Patch from Gregory Neil Shapiro of WPI. - CONFIG: don't allow an alias file in nullclient configurations -- - since all addresses are relayed, they give errors during - rebuild. Suggested by Per Hedeland of Ericsson. - CONFIG: local mailer on Solaris 2 should always get a -f flag because - otherwise the F=S causes the From_ line to imply that root is - the sender. Problem pointed out by Claude Scarpelli of - Infobiogen (France). - NEW FILES: - cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) - src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) - src/Makefiles/Makefile.UXPDS - -8.7/8.7 95/09/16 - Fix a problem that could cause sendmail to run out of file - descriptors due to a trashed data structure after a - vfork. Fix from Brian Coan of the Institute for - Global Communications. - Change the VRFY response if you have disabled VRFY -- some - people seemed to think that it was too rude. - Avoid reference to uninitialized file descriptor if HASFLOCK - was not defined. This was used "safely" in the sense - that it only did a stat, but it would have set the - map modification time improperly. Problem pointed out - by Roy Mongiovi of Georgia Tech. - Clean up the Subject: line on warning messages and return - receipts so that they don't say "Returned mail:"; this - can be confusing. - Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is - useful enough to make it worthwhile printing on "-d". - Avoid logging alias statistics every time you read the alias - file on systems with no database method compiled in. - If you have a name with a trailing dot, and you try looking it - up using gethostbyname without the dot (for /etc/hosts - compatibility), be sure to turn off RES_DEFNAMES and - RES_DNSRCH to avoid finding the wrong name accidently. - Problem noted by Charles Amos of the University of - Maryland. - Don't do timeouts in collect if you are not running SMTP. - There is nothing that says you can't have a long - running program piped into sendmail (possibly via - /bin/mail, which just execs sendmail). Problem reported - by Don "Truck" Lewis of Silicon Systems. - Try gethostbyname() even if the DNS lookup fails iff option I - is not set. This allows you to have hosts listed in - NIS or /etc/hosts that are not known to DNS. It's normally - a bad idea, but can be useful on firewall machines. This - should really be broken out on a separate flag, I suppose. - Avoid compile warnings against BIND 4.9.3, which uses function - prototypes. From Don Lewis of Silicon Systems. - Avoid possible incorrect diagnosis of DNS-related errors caused - by things like attempts to resolve uucp names using - $[ ... $] -- the fix is to clear h_errno at appropriate - times. From Kyle Jones of UUNET. - SECURITY: avoid denial-of-service attacks possible by destroying - the alias database file by setting resource limits low. - This involves adding two new compile-time options: - HASSETRLIMIT (indicating that setrlimit(2) support is - available) and HASULIMIT (indicating that ulimit(2) support - is available -- the Release 3 form is used). The former - is assumed on BSD-based systems, the latter on System - V-based systems. Attack noted by Phil Brandenberger of - Swarthmore University. - New syntaxes in test (-bt) mode: - ``.Dmvalue'' will define macro "m" to "value". - ``.Ccvalue'' will add "value" to class "c". - ``=Sruleset'' will dump the contents of the indicated - ruleset. - ``=M'' will display the known mailers. - ``-ddebug-spec'' is equivalent to the command-line - -d debug flag. - ``$m'' will print the value of macro $m. - ``$=c'' will print the contents of class $=c. - ``/mx host'' returns the MX records for ``host''. - ``/parse address'' will parse address, returning the value of - crackaddr (essentially, the comment information) - and the parsed address. - ``/try mailer address'' will rewrite address into the form - it will have when presented to the indicated mailer. - ``/tryflags flags'' will set flags used by parsing. The - flags can be `H' for header or `E' for envelope, - and `S' for sender or `R' for recipient. These - can be combined, so `HR' sets flags for header - recipients. - ``/canon hostname'' will try to canonify hostname and - return the result. - ``/map mapname key'' will look up `key' in the indicated - `mapname' and return the result. - Somewhat better handling of UNIX-domain socket addresses -- it - should show the pathname rather than hex bytes. - Restore ``-ba'' mode -- this reads a file from stdin and parses - the header for envelope sender information and uses - CR-LF as message terminators. It was thought to be - obsolete (used only for Arpanet NCP protocols), but it - turns out that the UK ``Grey Book'' protocols require - that functionality. - Fix a fix in previous release -- if gethostname and gethostbyname - return a name without dots, and if an attempt to canonify - that name fails, wait one minute and try again. This can - result in an extra 60 second delay on startup if your system - hostname (as returned by hostname(1)) has no dot and no names - listed in /etc/hosts or your NIS map have a dot. - Check for proper domain name on HELO and EHLO commands per - RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III - of Michigan Technological University. - Relax chownsafe rules slightly -- old version said that if you - can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, - if fpathconf returned EINVAL or ENOSYS), assume that - chown is not safe. The new version falls back to whether - you are on a BSD system or not. This is important for - SunOS, which apparently always returns one of those - error codes. This impacts whether you can mail to files - or not. - Syntax errors such as unbalanced parentheses in the configuration - file could be omitted if you had "Oem" prior to the - syntax error in the config file. Change to always print - the error message. It was especially weird because it - would cause a "warning" message to be sent to the Postmaster - for every message sent (but with no transcript). Problem - noted by Gregory Paris of Motorola. - Rewrite collect and putbody to handle full 8-bit data, including - zero bytes. These changes are internally extensive, but - should have minimal impact on external function. - Allow full words for option names -- if the option letter is - (apparently) a space, then take the word following -- e.g., - O MatchGECOS=TRUE - The full list of old and new names is as follows: - 7 SevenBitInput - 8 EightBitMode - A AliasFile - a AliasWait - B BlankSub - b MinFreeBlocks/MaxMessageSize - C CheckpointInterval - c HoldExpensive - D AutoRebuildAliases - d DeliveryMode - E ErrorHeader - e ErrorMode - f SaveFromLine - F TempFileMode - G MatchGECOS - H HelpFile - h MaxHopCount - i IgnoreDots - I ResolverOptions - J ForwardPath - j SendMimeErrors - k ConnectionCacheSize - K ConnectionCacheTimeout - L LogLevel - l UseErrorsTo - m MeToo - n CheckAliases - O DaemonPortOptions - o OldStyleHeaders - P PostmasterCopy - p PrivacyOptions - Q QueueDirectory - q QueueFactor - R DontPruneRoutes - r, T Timeout - S StatusFile - s SuperSafe - t TimeZoneSpec - u DefaultUser - U UserDatabaseSpec - V FallbackMXhost - v Verbose - w TryNullMXList - x QueueLA - X RefuseLA - Y ForkEachJob - y RecipientFactor - z ClassFactor - Z RetryFactor - The old macros that passed information into sendmail have - been changed to options; those correspondences are: - $e SmtpGreetingMessage - $l UnixFromLine - $o OperatorChars - $q (deleted -- not necessary) - To avoid possible problems with an older sendmail, - configuration level 6 is accepted by this version of - sendmail; any config file using the new names should - specify "V6" in the configuration. - Change address parsing to properly note that a phrase before a - colon and a trailing semicolon are essentially the same - as text outside of angle brackets (i.e., sendmail should - treat them as comments). This is to handle the - ``group name: addr1, addr2, ..., addrN;'' syntax (it will - assume that ``group name:'' is a comment on the first - address and the ``;'' is a comment on the last address). - This requires config file support to get right. It does - understand that :: is NOT this syntax, and can be turned - off completely by setting the ColonOkInAddresses option. - Level 6 config files added with new mailer flags: - A Addresses are aliasable. - i Do udb rewriting on envelope as well as header - sender lines. Applies to the from address mailer - flags rather than the recipient mailer flags. - j Do udb rewriting on header recipient addresses. - Applies to the sender mailer flags rather than the - recipient mailer flags. - k Disable check for loops when doing HELO command. - o Always run as the mail recipient, even on local - delivery. - w Check for an /etc/passwd entry for this user. - 5 Pass addresses through ruleset 5. - : Check for :include: on this address. - | Check for |program on this address. - / Check for /file on this address. - @ Look up sender header addresses in the user - database. Applies to the mailer flags for the - mailer corresponding to the envelope sender - address, rather than to recipient mailer flags. - Pre-level 6 configuration files set A, w, 5, :, |, /, and @ - on the "local" mailer, the o flag on the "prog" and "*file*" - mailers, and the ColonOkInAddresses option. - Eight-to-seven bit MIME conversions. This borrows ideas from - John Beck of Hewlett-Packard, who generously contributed - their implementation to me, which I then didn't use (see - mime.c for an explanation of why). This adds the - EightBitMode option (a.k.a. `8') and an F=8 mailer flag - to control handling of 8-bit data. These have to cope with - two types of 8-bit data: unlabelled 8-bit data (that is, - 8-bit data that is entered without declaring it as 8-bit - MIME -- technically this is illegal according to the - specs) and labelled 8-bit data (that is, it was declared - as 8BITMIME in the ESMTP session or by using the - -B8BITMIME command line flag). If the F=8 mailer flag is - set then 8-bit data is sent to non-8BITMIME machines - instead of converting to 7 bit (essentially using - just-send-8 semantics). The values for EightBitMode are: - m convert unlabelled 8-bit input to 8BITMIME, and do - any necessary conversion of 8BITMIME to 7BIT - (essentially, the full MIME option). - p pass unlabelled 8-bit input, but convert labelled - 8BITMIME input to 7BIT as required (default). - s strict adherence: reject unlabelled 8-bit input, - convert 8BITMIME to 7BIT as required. The F=8 - flag is ignored. - Unlabelled 8-bit data is rejected in mode `s' regardless of - the setting of F=8. - Add new internal class 'n', which is the set of MIME Content-Types - which can not be 8 to 7 bit encoded because of other - considerations. Types "multipart/*" and "message/*" are - never directly encoded (although their components can be). - Add new internal class 's', which is the set of subtypes of the - MIME message/* content type that can be treated as though - they are an RFC822 message. It is predefined to have - "rfc822". Suggested By Kari Hurtta. - Add new internal class 'e'. This is the set of MIME - Content-Transfer-Encodings that can be converted to - a seven bit format (Quoted-Printable or Base64). It is - preinitialized to contain "7bit", "8bit", and "binary". - Add C=charset mailer parameter and the the DefaultCharSet option (no - short name) to set the default character set to use in the - Content-Type: header when doing encoding of an 8-bit message - which isn't marked as MIME into MIME format. If the C= - parameter is set on the Envelope From address, use that as - the default encoding; else use the DefaultCharSet option. - If neither is set, it defaults to "unknown-8bit" as - suggested by RFC 1428 section 3. - Allow ``U=user:group'' field in mailer definition to set a default - user and group that a mailer will be executed as. This - overrides the 'u' and 'g' options, and if the `F=S' flag is - also set, it is the uid/gid that will always be used (that - is, the controlling address is ignored). The values may be - numeric or symbolic; if only a symbolic user is given (no - group) that user's default group in the passwd file is used - as the group. Based on code donated by Chip Rosenthal of - Unicom. - Allow `u' option to also accept user:group as a value, in the same - fashion as the U= mailer option. - Add the symbolic time zone name in the Arpanet format dates (as - a comment). This adds a new compile-time configuration - flag: TZ_TYPE can be set to TZ_TM_NAME (use the value - of (struct tm *)->tm_name), TZ_TM_ZONE (use the value - of (struct tm *)->tm_zone), TZ_TZNAME (use extern char - *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use - timezone()), or TZ_NONE (don't include the comment). Code - from Chip Rosenthal. - The "Timeout" option (formerly "r") is extended to allow suboptions. - For example, - O Timeout.helo = 2m - There are also two new suboptions "queuereturn" and - "queuewarn"; these subsume the old T option. Thus, to - set them both the preferred new syntax is - O Timeout.queuereturn = 5d - O Timeout.queuewarn = 4h - Sort queue by host name instead of by message priority if the - QueueSortOrder option (no short name) is set is set to - ``host''. This makes better use of the connection cache, - but may delay more ``interactive'' messages behind large - backlogs under some circumstances. This is probably a - good option if you have high speed links or don't do lots - of ``batch'' messages, but less good if you are using - something like PPP on a 14.4 modem. Based on code - contributed by Roy Mongiovi of Georgia Tech (my main - contribution was to make it configurable). - Save i-number of df file in qf file to simplify rebuilding of queue - after disasterous disk crash. Suggested by Kyle Jones of - UUNET; closely based on code from KJS DECWRL code written - by Paul Vixie. NOTA BENE: The qf files produced by 8.7 - are NOT back compatible with 8.6 -- that is, you can convert - from 8.6 to 8.7, but not the other direction. - Add ``F=d'' mailer flag to disable all use of angle brackets in - route-addrs in envelopes; this is because in some cases - they can be sent to the shell, which interprets them as - I/O redirection. - Don't include error file (option E) with return-receipts; this - can be confusing. - Don't send "Warning: cannot send" messages to owner-* or - *-request addresses. Suggested by Christophe Wolfhugel - of the Institut Pasteur, Paris. - Allow -O command line flag to set long form options. - Add "MinQueueAge" option to set the minimum time between attempts - to run the queue. For example, if the queue interval - (-q value) is five minutes, but the minimum queue age - is fifteen minutes, jobs won't be tried more often than - once every fifteen minutes. This can be used to give - you more responsiveness if your delivery mode is set to - queue-only. - Allow "fileopen" timeout (default: 60 seconds) for opening - :include: and .forward files. - Add "-k", "-v", and "-z" flags to map definitions; these set the - key field name, the value field name, and the field - delimiter. The field delimiter can be a single character - or the sequence "\t" or "\n" for tab or newline. - These are for use by NIS+ and similar access methods. - Change maps to always strip quotes before lookups; the -q flag - turns off this behaviour. Suggested by Motonori Nakamura. - Add "nisplus" map class. Takes -k and -v flags to choose the - key and value field names respectively. Code donated by - Sun Microsystems. - Add "hesiod" map class. The "file name" is used as the - "HesiodNameType" parameter to hes_resolve(3). Returns the - first value found for the match. Code donated by Scott - Hutton of Indiana University. - Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to - specify the name of the property that is searched as the - key and a -v flag to specify the name of the property that - is returned as the value (defaults to "members"). The - default map is "/aliases". Some code based on code - contributed by Robert La Ferla of Hot Software. - Add "text" map class. This does slow, linear searches through - text files. The -z flag specifies a column delimiter - (defaults to any sequence of white space), the -k flag - sets the key column number, and the -v flag sets the - value column number. Lines beginning with `#' are treated - as comments. - Add "program" map class to execute arbitrary programs. The search - key is presented as the last argument; the output is one - line read from the programs standard output. Exit statuses - are from sysexits.h. - Add "sequence" map class -- searches maps in sequence until it - finds a match. For example, the declarations: - Kmap1 ... - Kmap2 ... - Kmapseq sequence map1 map2 - defines a map "mapseq" that first searches map1; if the - value is found it is returned immediately, otherwise - map2 is searched and the value returned. - Add "switch" map class. This is much like "sequence" except that - the ordering is fetched from an external file, usually - the system service switch. The parameter is the name of - the service to switch on, and the maps that it will use - are the name of the switch map followed by ".service_type". - For example, if the declaration of the map is - Ksample switch hosts - and the system service switch specifies that hosts are - looked up using dns and nis in that order, then this is - equivalent to - Ksample sequence sample.dns sample.nis - The subordinate maps (sample.*) must already be defined. - Add "user" map class -- looks up users using getpwnam. Takes a - "-v field" flag on the definition that tells what passwd - entry to return -- legal values are name, passwd, uid, gid, - gecos, dir, and shell. Generally expected to be used with - the -m (matchonly) flag. - Add "bestmx" map class -- returns the best MX value for the host - listed as the value. If there are several "best" MX records - for this host, one will be chosen at random. - Add "userdb" map class -- looks up entries in the user database. - The "file name" is actually the tag that will be used, - typically "mailname". If there are multiple entries - matching the name, the one chosen is undefined. - Add multiple queue timeouts (both return and warning). These are - set by the Precedence: or Priority: header fields to one of - three values. If a Priority: is set and has value "normal", - "urgent", or "non-urgent" the corresponding timeouts are - used. If no priority is set, the Precedence: is consulted; - if negative, non-urgent timeouts are used; if greater than - zero, urgent timeouts are used. Otherwise, normal timeouts - are used. The timeouts are set by setting the six timeouts - queue{warn,return}.{urgent,normal,non-urgent}. - Fix problem when a mail address is resolved to a $#error mailer - with a temporary failure indication; it works in SMTP, - but when delivering locally the mail is silently discarded. - This patch, from Kyle Jones of UUNET, bounces it instead - of queueing it (queueing is very hard). - When using /etc/hosts or NIS-style lookups, don't assume that - the first name in the list is the best one -- instead, - search for the first one with a dot. For example, if - an /etc/hosts entry reads - 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU - this change will use the second name as the canonical - machine name instead of the initial, unqualified name. - Change dequote map to replace spaces in quoted text with a value - indicated by the -s flag on the dequote map definition. - For example, ``Mdequote dequote -s_'' will change - "Foo Bar" into an unquoted Foo_Bar instead of leaving it - quoted (because of the space character). Suggested by Dan - Oscarsson for use in X.400 addresses. - Implement long macro names as ${name}; long class names can - be similarly referenced as $={name} and $~{name}. - Definitions are (e.g.) ``D{name}value''. Names that have - a leading lower case letter or punctuation characters are - reserved for internal use by sendmail; i.e., config files - should use names that begin with a capital letter. Based - on code contributed by Dan Oscarsson. - Fix core dump if getgrgid returns a null group list (as opposed - to an empty group list, that is, a pointer to a list - with no members). Fix from Andrew Chang of Sun Microsystems. - Fix possible core dump if malloc fails -- if the malloc in xalloc - failed, it called syserr which called newstr which called - xalloc.... The newstr is now avoided for "panic" messages. - Reported by Stuart Kemp of James Cook University. - Improve connection cache timeouts; previously, they were not even - checked if you were delivering to anything other than an - IPC-connected host, so a series of (say) local mail - deliveries could cause cached connections to be open - much longer than the specified timeout. - If an incoming message exceeds the maximum message size, stop - writing the incoming bytes to the queue data file, since - this can fill your mqueue partition -- this is a possible - denial-of-service attack. - Don't reject all numeric local user names unless HESIOD is - defined. It turns out that Posix allows all-numeric - user names. Fix from Tony Sanders of BSDI. - Add service switch support. If the local OS has a service - switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf - on DEC systems) that will be used; otherwise, it falls back - to using a local mechanism based on the ServiceSwitchFile - option (default: /etc/service.switch). For example, if the - service switch lists "files" and "nis" for the aliases - service, that will be the default lookup order. the "files" - ("local" on DEC) service type expands to any alias files - you listed in the configuration file, even if they aren't - actually file lookups. - Option I (NameServerOptions) no longer sets the "UseNameServer" - variable which tells whether or not DNS should be considered - canonical. This is now determined based on whether or not - "dns" is in the service list for "hosts". - Add preliminary support for the ESMTP "DSN" extension (Delivery - Status Notifications). DSN notifications override - Return-Receipt-To: headers, which are bogus anyhow -- - support for them has been removed. - Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer - definitions to define the types used in DSN returns for - MTA names, addresses, and diagnostics respectively. - Extend heuristic to force running in ESMTP mode to look for the - five-character string "ESMTP" anywhere in the 220 greeting - message (not just the second line). This is to provide - better compatibility with other ESMTP servers. - Print sequence number of job when running the queue so you can - easily see how much progress you have made. Suggested - by Peter Wemm of DIALix. - Map newlines to spaces in logged message-ids; some versions of - syslog truncate the rest of the line after newlines. - Suggested by Fletcher Mattox of U. Texas. - Move up forking for job runs so that if a message is split into - multiple envelopes you don't get "fork storms" -- this - also improves the connection cache utilization. - Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for - the purposes of refusing to send error returns. Suggested - by Motonori Nakamura of Ritsumeikan University. - Relax rules on when a file can be written when referenced from - the aliases file: use the default uid/gid instead of the - real uid/gid. This allows you to create a file owned by - and writable only by the default uid/gid that will work - all the time (without having the setuid bit set). Change - suggested by Shau-Ping Lo and Andrew Cheng of Sun - Microsystems. - Add "DialDelay" option (no short name) to provide an "extra" - delay for dial on demand systems. If this is non-zero - and a connect fails, sendmail will wait this long and - then try again. If it takes longer than the kernel - timeout interval to establish the connection, this - option can give the network software time to establish - the link. The default units are seconds. - Move logging of sender information to be as early as possible; - previously, it could be delayed a while for SMTP mail - sent to aliases. Suggested by Brad Knowles of the - Defense Information Systems Agency. - Call res_init() before setting RES_DEBUG; this is required by - BIND 4.9.3, or so I'm told. From Douglas Anderson of - the National Computer Security Center. - Add xdelay= field in logs -- this is a transaction delay, telling - you how long it took to deliver to this address on the - last try. It is intended to be used for sorting mailing - lists to favor "quick" addresses. Provided for use by - the mailprio scripts (see below). - If a map cannot be opened, and that map is non-optional, and - an address requires that map for resolution, queue the - map instead of bouncing it. This involves creating a - pseudo-class of maps called "bogus-map" -- if a required - map cannot be opened, the class is changed to bogus-map; - all queries against bogus-map return "tempfail". The - bogus-map class is not directly accessible. A sample - implementation was donated by Jem Taylor of Glasgow - University Computing Service. - Fix a possible core dump when mailing to a program that talks - SMTP on its standard input. Fix from Keith Moore of - the University of Kentucky. - Make it possible to resolve filenames to $#local $: @ /filename; - previously, the "@" would cause it to not be recognized - as a file. Problem noted by Brian Hill of U.C. Davis. - Accept a -1 signal to re-exec the daemon. This only works if - argv[0] is a full path to sendmail. - Fix bug in "addr=..." field in O option on little-endian machines - -- the network number wasn't being converted to network - byte order. Patch from Kurt Lidl of Pix Technologies - Corporation. - Pre-initialize the resolver early on; this is to avoid a bug with - BIND 4.9.3 that can cause the _res.retry field to get - reset to zero, causing all name server lookups to time - out. Fix from Matt Day of Artisoft. - Restore T line (trusted users) in config file -- but instead of - locking out the -f flag, they just tell whether or not - an X-Authentication-Warning: will be added. This really - just creates new entries in class 't', so "Ft/file/name" - can be used to read trusted user names from a file. - Trusted users are also allowed to execute programs even - if they have a shell that isn't in /etc/shells. - Improve NEWDB alias file rebuilding so it will create them - properly if they do not already exist. This had been - a MAYBENEXTRELEASE feature in 8.6.9. - Check for @:@ entry in NIS maps before starting up to avoid - (but not prevent, sigh) race conditions. This ought to - be handled properly in ypserv, but isn't. Suggested by - Michael Beirne of Motorola. - Refuse connections if there isn't enough space on the filesystem - holding the queue. Contributed by Robert Dana of Wolf - Communications. - Skip checking for directory permissions in the path to a file - when checking for file permissions iff setreuid() - succeeded -- it is unnecessary in that case. This avoids - significant performance problems when looking for .forward - files. Based on a suggestion by Win Bent of USC. - Allow symbolic ruleset names. Syntax can be "Sname" to get an - arbitrary ruleset number assigned or "Sname = integer" - to assign a specific ruleset number. Reference is - $>name_or_number. Names can be composed of alphas, digits, - underscore, or hyphen (first character must be non-numeric). - Allow -o flag on AliasFile lines to make the alias file optional. - From Bryan Costales of ICSI. - Add NoRecipientAction option to handle the case where there is - no legal recipient header in the message. It can take - on values: - None Leave the message as is. The - message will be passed on even - though it is in technically - illegal syntax. - Add-To Add a To: header with any - recipients that it can find from - the envelope. This risks exposing - Bcc: recipients. - Add-Apparently-To Add an Apparently-To: header. This - has almost no redeeming social value, - and is provided only for back - compatibility. - Add-To-Undisclosed Add a header reading - To: undisclosed-recipients:; - which will have the effect of - making the message legal without - exposing Bcc: recipients. - Add-Bcc To add an empty Bcc: header. - There is a chance that mailers down - the line will delete this header, - which could cause exposure of Bcc: - recipients. - The default is NoRecipientAction=None. - Truncate (rather than delete) Bcc: lines in the header. This - should prevent later sendmails (at least, those that don't - themselves delete Bcc:) from considering this message to - be non-conforming -- although it does imply that non-blind - recipients can see that a Bcc: was sent, albeit not to whom. - Add SafeFileEnvironment option. If declared, files named as delivery - targets must be regular files in addition to the regular - checks. Also, if the option is non-null then it is used as - the name of a directory that is used as a chroot(2) - environment for the delivery; the file names listed in an - alias or forward should include the name of this root. - For example, if you run with - O SafeFileEnvironment=/arch - then aliases should reference "/arch/rest/of/path". If a - value is given, sendmail also won't try to save to - /usr/tmp/dead.letter (instead it just leaves the job in the - queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. - Support -A flag for alias files; this will comma concatenate like - entries. For example, given the aliases: - list: member1 - list: member2 - and an alias file declared as: - OAhash:-A /etc/aliases - the final alias inserted will be "list: member1,member2"; - without -A you will get an error on the second and subsequent - alias for "list". Contributed by Bryan Costales of ICSI. - Line-buffer transcript file. Suggested by Liudvikas Bukys. - Fix a problem that could cause very long addresses to core dump in - some special circumstances. Problem pointed out by Allan - Johannesen. - (Internal change.) Change interface to expand() (macro expansion) - to be simpler and more consistent. - Delete check for funny qf file names. This didn't really give - any extra security and caused some people some problems. - (If you -really- want this, define PICKY_QF_NAME_CHECK - at compile time.) Suggested by Kyle Jones of UUNET. - (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and - merge with DSN code; this is simpler and more consistent. - This may affect some people who have written their own - checkcompat() routine. - (Internal change.) Eliminate `D' line in qf file. The df file - is now assumed to be the same name as the qf file (with - the `q' changed to a `d', of course). - Avoid forking for delivery if all recipient mailers are marked as - "expensive" -- this can be a major cost on some systems. - Essentially, this forces sendmail into "queue only" mode - if all it is going to do is queue anyway. - Avoid sending a null message in some rather unusual circumstances - (specifically, the RCPT command returns a temporary - failure but the connection is lost before the DATA - command). Fix from Scott Hammond of Secure Computing - Corporation. - Change makesendmail to use a somewhat more rational naming scheme: - Makefiles and obj directories are named $os.$rel.$arch, - where $os is the operating system (e.g., SunOS), $rel is - the release number (e.g., 5.3), and $arch is the machine - architecture (e.g., sun4). Any of these can be omitted, - and anything after the first dot in a release number can - be replaced with "x" (e.g., SunOS.4.x.sun4). The previous - version used $os.$arch.$rel and was rather less general. - Change makesendmail to do a "make depend" in the target directory - when it is being created. This involves adding an empty - "depend:" entry in most Makefiles. - Ignore IDENT return value if the OSTYPE field returns "OTHER", - as indicated by RFC 1413. Pointed out by Kari Hurtta - of the Finnish Meteorological Institute. - Fix problem that could cause multiple responses to DATA command - on header syntax errors (e.g., lines beginning with colons). - Problem noted by Jens Thomassen of the University of Oslo. - Don't let null bytes in headers cause truncation of the rest of - the header. - Log Authentication-Warning:s. Suggested by Motonori Nakamura. - Increase timeouts on message data puts to allow time for receivers - to canonify addresses in headers on the fly. This is still - a rather ugly heuristic. From Motonori Nakamura. - Add "HasWildcardMX" suboption to ResolverOptions; if set, MX - records are not used when canonifying names, and when MX - lookups are done for addressing they must be fully - qualified. This is useful if you have a wildcard MX record, - although it may cause other problems. In general, don't use - wildcard MX records. Patch from Motonori Nakamura. - Eliminate default two-line SMTP greeting message. Instead of - adding an extra "ESMTP spoken here" line, the word "ESMTP" - is added between the first and second word of the first - line of the greeting message (i.e., immediately after the - host name). This eliminates the need for the BROKEN_SMTP_PEERS - compile flag. Old sendmails won't see the ESMTP, but that's - acceptable because SIZE was the only useful extension that - old sendmails understand. - Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 - invoked state dumps. From Masaharu Onishi. - Allow on-line comments in .forward and :include: files; they are - introduced by the string "#@#", where - is a space or a tab. This is intended for native - representation of non-ASCII sets such as Japanese, where - existing encodings would be unreadable or would lose - data -- for example, - NAKAMURA Motonori - (romanized/less information) - =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= - =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= - (with MIME encoding, not human readable) - #@# ^[$BCfB<^[(B ^[$BAGE5^[(B - (native encoding with ISO-2022-JP) - The last form is human readable in the Japanese environment. - Based on a fix from (surprise!) Motonori Nakamura. - Don't make SMTP error returns on MAIL FROM: line be "sticky" for all - messages to that host; these are most frequently associated - with addresses rather than the host, with the exception of - 421 (service shutting down). The effect was to cause queues - to sometimes take an excessive time to flush. Reported by - Robert Sargent of Southern Geographics Technologies and - Eric Prestemon of American University. - Add Nice=N mailer option to set the niceness at which a mailer will - run. This is actually a relative niceness (that is, an - increment on the background value). - Log queue runs that are skipped due to high loads. They are logged - at LOG_INFO priority iff the log level is > 8. Contributed - by Bruce Nagel of Data General. - Allow the error mailer to accept a DSN-style error status code - instead of an sysexits status code in the host part. - Anything with a dot will be interpreted as a DSN-style code. - Add new mailer flag: F=3 will tell translations to Quoted-Printable - to encode characters that might be munged by an EBCDIC system - in addition to the set required by RFC 1521. The additional - characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. - (Think of "IBM 360" as the mnemonic for this flag.) - Change check for mailing to files to look for a pathname of [FILE] - rather than looking for the mailer named *file*. The mapping - of leading slashes still goes to the *file* mailer. This - allows you to implement the *file* mailer as a separate - program, for example, to insert a Content-Length: header - or do special security policy. However, note that the usual - initial checking for the file permissions is still done, and - the program in question needs to be very careful about how - it does the file write to avoid security problems. - Be able to read ~root/.forward even if the path isn't accessible to - regular users. This is disrecommended because sendmail - sometimes does not run as root (e.g., when an unsafe option - is specified on the command line), but should otherwise be - safe because .forward files must be owned by the user for - whom mail is being forwarded, and cannot be a symbolic link. - Suggested by Forrest Aldrich of Wang Laboratories. - Add new "HostsFile" option that is the pathname to the /etc/hosts - file. This is used for canonifying hostnames when the - service type is "files". - Implement programs on F (read class from file) line. The syntax is - Fc|/path/to/program to read the output from the program - into class "c". - Probe the network interfaces to find alternate names for this - host. Requires the SIOCGIFCONF ioctl call. Code - contributed by SunSoft. - Add "E" configuration line to set or propogate environment - variables into children. "E" will propogate - the named variable from the environment when sendmail - was invoked into any children it calls; "E=" - sets the named variable to the indicated value. Any - variables not explicitly named will not be in the child - environment. However, sendmail still forces an - "AGENT=sendmail" environment variable, in part to enforce - at least one environment variable, since many programs and - libraries die horribly if this is not guaranteed. - Change heuristic for rebuilding both NEWDB and NDBM versions of - alias databases -- new algorithm looks for the substring - "/yp/" in the file name. This is more portable and involves - less overhead. Suggested by Motonori Nakamura. - Dynamically allocate the queue work list so that you don't lose - jobs in large queue runs. The old QUEUESIZE compile parameter - is replaced by QUEUESEGSIZE (the unit of allocation, which - should not need to be changed) and the MaxQueueRunSize option, - which is the absolute maximum number of jobs that will ever - be handled in a single queue run. Based on code contributed - by Brian Coan of the Institute for Global Communications. - Log message when a message is dropped because it exceeds the maximum - message size. Suggested by Leo Bicknell of Virginia Tech. - Allow trusted users (those on a T line or in $=t) to use -bs without - an X-Authentication-Warning: added. Suggested by Mark Thomas - of Mark G. Thomas Consulting. - Announce state of compile flags on -d0.1 (-d0.10 throws in the - OS-dependent defines). The old semantic of -d0.1 to not - run the daemon in background has been moved to -d99.100, - and the old 52.5 flag (to avoid disconnect() from closing - all output files) has been moved to 52.100. This makes - things more consistent (flags below .100 don't change - semantics) and separates out the backgrounding so that - it doesn't happen automatically on other unrelated debugging - flags. - If -t is used but no addresses are found in the header, give an - error message rather than just doing nothing. Fix from - Motonori Nakamura. - On systems (like SunOS) where the effective gid is not necessarily - included in the group list returned by getgroups(), the - `restrictmailq' option could sometimes cause an authorized - user to not be able to use `mailq'. Fix from Charles Hannum - of MIT. - Allow symbolic service names for [IPC] mailers. Suggested by - Gerry Magennis of Logica International. - Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs - when running DNS. For example, if the name FTP.Foo.ORG is - a CNAME for Cruft.Foo.ORG, then when sitting on a machine in - the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" - if this option is not set, or "FTP.Foo.ORG" if it is set. - This is technically illegal under RFC 822 and 1123, but the - IETF is moving toward legalizing it. Note that turning on - this option is not sufficient to guarantee that a downstream - neighbor won't rewrite the address for you. - Add "-m" flag to makesendmail script -- this tells you what object - directory and Makefile it will use, but doesn't actually do - the make. - Do some additional checking on the contents of the qf file to try - to detect attacks against the qf file. In particular, - abort on any line beginning "From ", and add an "end of - file" line -- any data after that line is prohibited. - Always use /etc/sendmail.cf, regardless of the arbitrary vendor - choices. This can be overridden in the Makefile by using - either -DUSE_VENDOR_CF_PATH to get the vendor location - (to the extent that we know it) or by defining - _PATH_SENDMAILCF (which is a "hard override"). This allows - sendmail 8 to have more consistent installation instructions. - Allow macros on `K' line in config file. Suggested by Andrew Chang - of Sun Microsystems. - Improved symbol table hash function from Eric Wassenaar. This one - is at least 50% faster. - Fix problem that didn't notice that timeout on file open was a - transient error. Fix from Larry Parmelee of Cornell - University. - Allow comments (lines beginning with a `#') in files read for - classes. Suggested by Motonori Nakamura. - Make SIGINT (usually ^C) in test mode return to the prompt instead - of dropping out entirely. This makes testing some of the - name server lookups easier to deal with when there are - hung servers. From Motonori Nakamura. - Add new ${opMode} macro that is set to the current operation mode - (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by - Claude Marinier . - Add new delivery mode (Odd) that defers all map lookups to queue runs. - Kind of like queue-only mode (Odq) except it tries to avoid - any external service requests; for dial-on-demand hosts that - want to minimize DNS lookups when mail is being queued. For - this to work you will also have to make sure that gethostbyname - of your local host name does not do a DNS lookup. - Improved handling of "out of space" conditions from John Myers of - Carnegie Mellon. - Improved security for mailing to files on systems that have fchmod(2) - support. - Improve "cannot send message for N days" message -- now says "could - not send for past N days". Suggested by Tom Moore of AT&T - Global Information Solutions. - Less misleading Subject: line on messages sent to postmaster only. - From Motonori Nakamura. - Avoid duplicate error messages on bad command line flags. From - Motonori Nakamura. - Better error message for case where ruleset 0 falls off the end - or otherwise does not resolve to a canonical triple. - Fix a problem that could cause multiple bounce messages if a bad - address was sent along with a good address to an SMTP - site where that SMTP site returned a 4yz code in response - to the final dot of the data. Problem reported by David - James of British Telecom. - Add "volatile" declarations so that gcc -O2 will work. Patches - from Alexander Dupuy of System Management ARTS. - Delete duplicates in MX lists -- believe it or not, there are sites - that list the same host twice in an MX list. This deletion - only works on adjacent preferences, so an MX list that - had A=5, B=10, A=15 would leave both As, but one that had - A=5, A=10, B=15 would reduce to A, B. This is intentional, - just in case there is something weird I haven't thought of. - Suggested by Barry Shein of Software Tool & Die. - SECURITY: .forward files cannot be symbolic links. If they are, - a bad guy can read your private files. - PORTABILITY FIXES: - Solaris 2 from Rob McMahon . - System V Release 4 from Motonori Nakamura of Ritsumeikan - University. This expands the disk size - checking to include all (?) SVR4 configurations. - System V Release 4 from Kimmo Suominen -- initgroups(3) - and setrlimit(2) are both available. - System V Release 4 from sob@sculley.ffg.com -- some versions - apparently "have EX_OK defined in other headerfiles." - Linux Makefile typo. - Linux getusershell(3) is broken in Slackware 2.0 -- - from Andrew Pam of Xanadu Australia. - More Linux tweaking from John Kennedy of California State - University, Chico. - Cray changes from Eric Wassenaar: ``On Cray, shorts, - ints, and longs are all 64 bits, and all structs - are multiples of 64 bits. This means that the - sizeof operator returns only multiples of 8. - This requires adaptation of code that really - deals with 32 bit or 16 bit fields, such as IP - addresses or nameserver fields.'' - DG/UX 5.4.3 from Mark T. Robinson . To - get the old behaviour, use -DDGUX_5_4_2. - DG/UX hack: add _FORCE_MAIL_LOCAL_=yes environment - variable to fix bogus /bin/mail behaviour. - Tandem NonStop-UX from Rick McCarty . - This also cleans up some System V Release 4 compile - problems. - Solaris 2: sendmail.cw file should be in /etc/mail to - match all the other configuration files. Fix - from Glenn Barry of Emory University. - Solaris 2.3: compile problem in conf.c. Fix from Alain - Nissen of the University of Liege, Belgium. - Ultrix: freespace calculation was incorrect. Fix from - Takashi Kizu of Osaka University. - SVR4: running in background gets a SIGTTOU because the - emulation code doesn't realize that "getpeername" - doesn't require reading the file. Fix from Peter - Wemm of DIALix. - Solaris 2.3: due to an apparent bug in the socket emulation - library, sockets can get into a "wedged" state where - they just return EPROTO; closing and re-opening the - socket clears the problem. Fix from Bob Manson - of Ohio State University. - Hitachi 3050R & 3050RX running HI-UX/WE2: portability - fixes from Akihiro Hashimoto ("Hash") of Chiba - University. - AIX changes to allow setproctitle to work from Rainer Schöpf - of Zentrum für Datenverarbeitung der Universität - Mainz. - AIX changes for load average from Ed Ravin of NASA/Goddard. - SCO Unix from Chip Rosenthal of Unicom (code was using the - wrong statfs call). - ANSI C fixes from Adam Glass (NetBSD project). - Stardent Titan/ANSI C fixes from Kate Hedstrom of Rutgers - University. - DG-UX fixes from Bruce Nagel of Data General. - IRIX64 updates from Mark Levinson of the University of - Rochester Medical Center. - Altos System V (``the first UNIX/XENIX merge the Altos - did for their Series 1000 & Series 2000 line; - their merged code was licenced back to AT&T and - Microsoft and became System V release 3.2'') from - Tim Rice . - OSF/1 running on Intel Paragon from Jeff A. Earickson - of Intel Scalable Systems - Divison. - Amdahl UTS System V 2.1.5 (SVr3-based) from Janet Jackson - . - System V Release 4 (statvfs semantic fix) from Alain - Durand of I.M.A.G. - HP-UX 10.x multiprocessor load average changes from - Scott Hutton and Jeff Sumler of Indiana University. - Cray CSOS from Scott Bolte of Cray Computer Corporation. - Unicos 8.0 from Douglas K.

Suggested by Allan Johannesen. - UnixWare 2.0 fixes from Petr Lampa of the Technical - University of Brno (Czech Republic). - KSR OS 1.2.2 support from Todd Miller of the University - of Colorado. - UX4800 support from Kazuhisa Shimizu of NEC. - MAKEMAP: allow -d flag to allow insertion of duplicate aliases - in type ``btree'' maps. The semantics of this are undefined - for regular maps, but it can be useful for the user database. - MAKEMAP: lock database file while rebuilding to avoid sendmail - lookups while the rebuild is going on. There is a race - condition between the open(... O_TRUNC ...) and the lock - on the file, but it should be quite small. - SMRSH: sendmail restricted shell added to the release. This can - be used as an alternative to /bin/sh for the "prog" mailer, - giving the local administrator more control over what - programs can be run from sendmail. - MAIL.LOCAL: add this local mailer to the tape. It is not really - part of the release proper, and isn't fully supported; in - particular, it does not run on System V based systems and - never will. - CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon - to allow rmail to compile on systems that don't have - function prototypes and systems that don't have snprintf. - CONTRIB: add the "mailprio" scripts that will help you sort mailing - lists by transaction delay times so that addresses that - respond quickly get sent first. This is to prevent very - sluggish servers from delaying other peoples' mail. - Contributed by Tony Sanders of BSDI. - CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders - of BSDI. This has a lot of comments to help people out. - CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, - put this on the m4 command line. On GNU m4 (which - supports the __file__ primitive) you can run m4 in an - arbitrary directory -- use either: - m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf - or - m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf - On other versions of m4 that don't support __file__, you - can use: - m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... - (Note the trailing slash on the _CF_DIR_ definition.) - Old versions of m4 will default to _CF_DIR_=.. for back - compatibility. - CONFIG: fix mail from <> so it will properly convert to - MAILER-DAEMON on local addresses. - CONFIG: fix code that was supposed to catch colons in host - names. Problem noted by John Gardiner Myers of CMU. - CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. - From Paul Riddle of the University of Maryland, Baltimore - County. - CONFIG: Catch and reject "." as a host address. - CONFIG: Generalize domaintable to look up all domains, not - just unqualified ones. - CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it - was never used and didn't work anyway. - CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer - and d on all mailers in the UUCP class. - CONFIG: Allow "user+detail" to be aliased specially: it will first - look for an alias for "user+detail", then for "user+*", and - finally for "user". This is intended for forwarding mail - for system aliases such as root and postmaster to a - centralized hub. - CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). - CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. - The F=8 flag is also set on the "relay" mailer, since - this is expected to be another sendmail. - CONFIG: avoid qualifying all UUCP addresses sent via SMTP with - the name of the UUCP_RELAY -- in some cases, this is the - wrong value (e.g., when we have local UUCP connections), - and this can create unreplyable addresses. From Chip - Rosenthal of Unicom. - CONFIG: add confRECEIVED_HEADER to change the format of the - Received: header inserted into all messages. Suggested by - Gary Mills of the University of Manitoba. - CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) - to get the old behaviour. I did this upon observing - that almost everyone needed this feature, and that the - concept I was trying to make happen didn't work with - some user agents anyway. FEATURE(notsticky) still works, - but it is a no-op. - CONFIG: Add LUSER_RELAY -- the host to which unrecognized user - names are sent, rather than immediately diagnosing them - as User Unknown. - CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, - and RELAY_MAILER_ARGS to set the arguments for the - indicated mailers. All default to "IPC $h". Patch from - Larry Parmelee of Cornell University. - CONFIG: pop mailer needs F=n flag to avoid "annoying side effects - on the client side" and F=P to get an appropriate - return-path. From Kimmo Suominen. - CONFIG: add FEATURE(local_procmail) to use the procmail program - as the local mailer. For addresses of the form "user+detail" - the "detail" part is passed to procmail via the -a flag. - Contributed by Kimmo Suominen. - CONFIG: add MAILER(procmail) to add an interface to procmail for - use from mailertables. This lets you execute arbitrary - procmail scripts. Contributed by Kimmo Suominen. - CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. - CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From - Paul Southworth of CICNet Systems Support. - CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. - This causes the null return path to be rewritten as - MAILER-DAEMON; otherwise UUCP gets horribly confused. - From Michael Hohmuth of Technische Universitat Dresden. - CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that - list us as the best possible MX record to be treated as - though they were local (essentially, assume that they - are included in $=w). This can cause additional DNS - traffic, but is easier to administer if this fits your - local model. It does not work reliably if there are - multiple hosts that share the best MX preference. - Code contributed by John Oleynick of Rutgers. - CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted - SHell) instead of /bin/sh as the program used for delivery - to programs. If an argument is included, it is used as - the path to smrsh; otherwise, /usr/local/etc/smrsh is - assumed. - CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the - size of messages to the local and procmail mailers - respectively. Contributed by Brad Knowles of the Defense - Information Systems Agency. - CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments - (just like text outside of angle brackets) in order to - properly deal with ``group: addr1, ... addrN;'' syntax. - CONFIG: Require OSTYPE macro (the defaults really don't apply to - any real systems any more) and tweak the DOMAIN macro - so that it is less likely that users will accidently use - the Berkeley defaults. Also, create some generic files - that really can be used in the real world. - CONFIG: Add new configuration macros to set character sets for - messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, - SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. - CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. - The old name will still be accepted for a while at least. - CONFIG: Implement DECNET_RELAY as spec for host to which DECNET - mail (.DECNET pseudo-domain or node::user) will be sent. - As with all relays, it can be ``mailer:hostname''. Suggested - by Scott Hutton. - CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed - by Barb Dijker of Labyrinth Computer Services. - CONFIG: change confCHECK_ALIASES to default to False -- it has poor - performance for large alias files, and this confused many - people. - CONFIG: Add confCF_VERSION to append local information to the - configuration version number displayed during SMTP startup. - CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it - would only work when locally addressed. Fix from - Edvard Tuinder of Cistron Internet Services. - CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option - "n" (CheckAlaises) is set when rebuilding alias database. - Based on code contributed by Claude Marinier. - CONFIG: Allow mailertable to have values of the form - ``error:code message''. The ``code'' is a status code - derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. - Contributed by David James . - CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of - sender domains that will be replaced with the masquerade name. - These domains will not be treated as local, but if mail passes - through with sender addresses in those domains they will be - replaced by the masquerade name. These can also be specified - in a file using MASQUERADE_DOMAIN_FILE(filename). - CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope - as well as the header. Substantial improvements to this - code were contributed by Per Hedeland. - CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be - accessed from a mailertable to do CCSO ph lookups. Contributed - by Kimmo Suominen. - CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be - used to define cyrus and cyrusbb mailers (for IMAP support). - Contributed by John Gardiner Myers of Carnegie Mellon. - CONFIG: add confUUCP_MAILER to select default mailer to use for - UUCP addressing.

Fix from several - people, including Allan Johannesen, Shane Castle of the - Boulder County Information Services, and Jeff Smith of - Warwick University (all arrived within a few hours of - each other!). - Fix a problem that could cause large jobs to run out of - file descriptors on systems that use vfork() rather - than fork(). - -8.6.11/8.6.11 95/03/08 - The ``possible attack'' message would be logged more often - than necessary if you are using Pine as a user agent. - The wrong host would be reported in the ``possible attack'' - message when attempted from IDENT. - In some cases the syslog buffer could be overflowed when - reporting the ``possible attack'' message. This can - cause denial of service attacks. Truncate the message - to 80 characters to prevent this problem. - When reading the IDENT response a loop is needed around the - read from the network to ensure that you don't get - partial lines. - Password entries without any shell listed (that is, a null - shell) wouldn't match as "ok". Problem noted by - Rob McMahon. - When running BIND 4.9.x a problem could occur because the - _res.options field is initialized differently than it - was historically -- this requires that sendmail call - res_init before it tweaks any bits. - Fix an incompatibility in openxscript() between the file open mode - and the stdio mode passed to fdopen. This caused UnixWare - 2.0 to have conniptions. Fix from Martin Sohnius of - Novell Labs Europe. - Fix problem with static linking of local getopt routine when - using GNU's ld command. Fix from John Kennedy of - Cal State Chico. - It was possible to turn off privacy flags. Problem noted by - *Hobbit*. - Be more paranoid about writing files. Suggestions by *Hobbit* - and Liudvikas Bukys. - MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) - from Spider Boardman. - CONFIG: No changes (version number only, to keep it in sync - with the binaries). - -8.6.10/8.6.10 95/02/10 - SECURITY: Diagnose bogus values to some command line flags that - could allow trash to get into headers and qf files. - Validate the name of the user returned by the IDENT protocol. - Some systems that really dislike IDENT send intentionally - bogus information. Problem pointed out by Michael Bushnell - of the Free Software Foundation. Has some security - implications. - Fix a problem causing error messages about DNS problems when - the host name contained a percent sign to act oddly - because it was passed as a printf-style format string. - In some cases this could cause core dumps. - Avoid possible buffer overrun in returntosender() if error - message is quite ling. From Fletcher Mattox of the - University of Texas. - Fix a problem that would silently drop "too many hops" error - messages if and only if you were sending to an alias. - From Jon Giltner of the University of Colorado and - Dan Harton of Oak Ridge National Laboratory. - Fix a bug that caused core dumps on some systems if -d11.2 was - set and e->e_message was null. Fix from Bruce Nagel of - Data General. - Fix problem that can still cause df files to be left around - after "hop count exceeded" messages. Fix from Andrew - Chang and Shau-Ping Lo of SunSoft. - Fix a problem that can cause buffer overflows on very long - user names (as might occur if you piped to a program - with a lot of arguments). - Avoid returning an error and re-queueing if the host signature - is null; this can occur on addresses like ``user@.''. - Problem noted by Wesley Craig and the University of - Michigan. - Avoid possible calls to malloc(0) if MCI caching is turned - off. Bug fix from Pierre David of the Laboratoire - Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), - Universite de Versailles - St Quentin, and Jacky - Thibault. - Make a local copy of the line being sent via senttolist() -- in - some cases, buffers could get trashed by map lookups - causing it to do unexpected things. This also simplifies - some of the map code. - CONFIG: No changes (version number only, to keep it in sync - with the binaries). - -8.6.9/8.6.9 94/04/19 - Do all mail delivery completely disconnected from any terminal. - This provides consistency with daemon delivery and - may have some security implications. - Make sure that malloc doesn't get called with zero size, - since that fails on some systems. Reported by Ed - Hill of the University of Iowa. - Fix multi-line values for $e (SMTP greeting message). Reported - by Mike O'Connor of Ford Motor Company. - Avoid syserr if no NIS domain name is defined, but the map it - is trying to open is optional. From Win Bent of USC. - Changes for picky compilers from Ed Gould of Digital Equipment. - Hesiod support for UDB from Todd Miller of the University of - Colorado. Use "hesiod" as the service name in the U - option. - Fix a problem that failed to set the "authentic" host name (that - is, the one derived from the socket info) if you called - sendmail -bs from inetd. Based on code contributed by - Todd Miller (this problem was also reported by Guy Helmer - of Dakota State University). This also fixes a related - problem reported by Liudvikas Bukys of the University of - Rochester. - Parameterize "nroff -h" in all the Makefiles so people with - variant versions can use them easily. Suggested by - Peter Collinson of Hillside Systems. - SMTP "MAIL" commands with multiple ESMTP parameters required two - spaces between parameters instead of one. Reported by - Valdis Kletnieks of Virginia Tech. - Reduce the number of system calls during message collection by - using global timeouts around the collect() loop. This - code was contributed by Eric Wassenaar. - If the initial hostname name gathering results in a name - without a dot (usually caused by NIS misconfiguration) - and BIND is compiled in, directly access DNS to get - the canonical name. This should make life easier for - Solaris systems. If it still can't be resolved, and - if the name server is listed as "required", try again - in 30 seconds. If that also fails, exit immediately to - avoid bogus "config error: mail loops back to myself" - messages. - Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error - message to explain how much space was available and - sound a bit less threatening. Suggested by Stan Janet - of the National Institute of Standards and Technology. - If mail is delivered to an alias that has an owner, deliver any - requested return-receipt immediately, and strip the - Return-Receipt-To: header from the subsequent message. - This prevents a certain class of denial of service - attack, arguably gives more reasonable semantics, and - moves things more towards what will probably become a - network standard. Suggested by Christopher Davis of - Kapor Enterprises. - Add a "noreceipts" privacy flag to turn off all return receipts - without recompiling. - Avoid printing ESMTP parameters as part of the error message - if there are errors during parsing. This change is - purely cosmetic. - Avoid sending out error messages during the collect phase of - SMTP; there is an MVS mailer from UCLA that gets - confused by this. Of course, I think it's their bug.... - Check for the $j macro getting undefined, losing a dot, or getting - lost from $=w in the daemon before accepting a connection; - if it is, it dumps state, prints a LOG_ALERT message, - and drops core for debugging. This is an attempt to - track down a bug that I thought was long since gone. - If you see this, please forward the log fragment to - sendmail@sendmail.ORG. - Change OLD_NEWDB from a #ifdef to a #if so it can be turned off - with -DOLD_NEWDB=0 on the command line. From Christophe - Wolfhugel. - Instead of trying to truncate the listen queue for the server - SMTP port when the load average is too high, just close - the port completely and reopen it later as needed. - This ensures that the other end gets a quick "connection - refused" response, and that the connection can be - recovered later. In particular, some socket emulations - seem to get confused if you tweak the listen queue - size around and can never start listening to connections - again. The down side is that someone could start up - another daemon process in the interim, so you could - have multiple daemons all not listening to connections; - this could in turn cause the sendmail.pid file to be - incorrect. A better approach might be to accept the - connection and give a 421 code, but that could break - other mailers in mysterious ways and have paging behaviour - implications. - Fix a glitch in TCP-level debugging that caused flag 16.101 to - set debugging on the wrong socket. From Eric Wassenaar. - When creating a df* temporary file, be sure you truncate any - existing data in the file -- otherwise system crashes - and the like could result in extra data being sent. - DOC: Replace the CHANGES-R5-R8 readme file with a paper in the - doc directory. This includes some additional - information. - CONFIG: change UUCP rules to never add $U! or $k! on the front - of recipient envelope addresses. This should have been - handled by the $&h trick, but broke if people were - mixing domainized and UUCP addresses. They should - probably have converted all the way over to uucp-uudom - instead of uucp-{new,old}, but the failure mode was to - loop the mail, which was bad news. - Portability fixes: - Newer BSDI systems (several people). - Older BSDI systems from Christophe Wolfhugel. - Intergraph CLIX, from Paul Southworth of CICNet. - UnixWare, from Evan Champion. - NetBSD from Adam Glass. - Solaris from Quentin Campbell of the University of - Newcastle upon Tyne. - IRIX from Dean Cookson and Bill Driscoll of Mitre - Corporation. - NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. - SunOS (it has setsid() and setvbuf() calls) from - Jonathan Kamens of OpenVision Technologies. - HP-UX from Tor Lillqvist. - New Files: - src/Makefile.CLIX - src/Makefile.NCR3000 - doc/changes/Makefile - doc/changes/changes.me - doc/changes/changes.ps - -8.6.8/8.6.6 94/03/21 - SECURITY: it was possible to read any file as root using the - E (error message) option. Reported by Richard Jones; - fixed by Michael Corrigan and Christophe Wolfhugel. - -8.6.7/8.6.6 94/03/14 - SECURITY: it was possible to get root access by using weird - values to the -d flag. Thanks to Alain Durand of - INRIA for forwarding me the notice from the bugtraq - list. - -8.6.6/8.6.6 94/03/13 - SECURITY: the ability to give files away on System V-based - systems proved dangerous -- don't run as the owner - of a :include: file on a system that allows giveaways. - Unfortunately, this also applies to determining a - valid shell. - IMPORTANT: Previous versions weren't expiring old connections - in the connection cache for a long time under some - circumstances. This could result in resource exhaustion, - both at your end and at the other end. This checks the - connections for timeouts much more frequently. From - Doug Anderson of NCSC. - Fix a glitch that snuck in that caused programs to be run as - the sender instead of the recipient if the mail was - from a local user to another local user. From - Motonori Nakamura of Kyoto University. - Fix "wildcard" on /etc/shells matching -- instead of looking - for "*", look for "/SENDMAIL/ANY/SHELL/". From - Bryan Costales of ICSI. - Change the method used to declare the "statfs" availability; - instead of HASSTATFS and/or HASUSTAT with a ton of - tweaking in conf.c, there is a single #define called - SFS_TYPE which takes on one of six values (SFS_NONE - for no statfs availability, SFS_USTAT for the ustat(2) - syscall, SFS_4ARGS for a four argument statfs(2) call, - and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument - statfs(2) call with the declarations in , - , or respectively). - Fix glitch in NetInfo support that could return garbage if - there was no "/locations/sendmail" property. From - David Meyer of the University of Virginia. - Change HASFLOCK from defined/not-defined to a 0/1 definition - to allow Linux to turn it off even though it is a - BSD-like system. - Allow setting of "ident" timeout to zero to turn off the ident - protocol entirely. - Make 7-bit stripping local to a connection (instead of to a - mailer); this allows you to specify that SMTP is a - 7-bit channel, but revert to 8-bit should it advertise - that it supports 8BITMIME. You still have to specify - mailer flag 7 to get this stripping at all. - Improve makesendmail script so it handles more cases automatically. - Tighten up restrictions on taking ownership of :include: files - to avoid problems on systems that allow you to give away - files. - Fix a problem that made it impossible to rebuild the alias - file if it was on a read-only file system. From - Harry Edmon of the University of Washington. - Improve MX randomization function. From John Gardiner Myers - of CMU. - Fix a minor glitch causing a bogus message to be printed (used - %s instead of %d in a printf string for the line number) - when a bad queue file was read. From Harry Edmon. - Allow $s to remain NULL on locally generated mail. I'm not - sure this is necessary, but a lot of people have complained - about it, and there is a legitimate question as to whether - "localhost" is legal as an 822-style domain. - Fix a problem with very short line lengths (mailer L= flag) in - headers. This causes a leading space to be added onto - continuation lines (including in the body!), and also - tries to wrap headers containing addresses (From:, To:, - etc) intelligently at the shorter line lengths. Problem - Reported by Lars-Johan Liman of SUNET Operations Center. - Log the real user name when logging syserrs, since these can have - security implications. Suggested by several people. - Fix address logging of cached connections -- it used to always - log the numeric address as zero. This is a somewhat - bogus implementation in that it does an extra system - call, but it should be an inexpensive one. Fix from - Motonori Nakamura. - Tighten up handling of short syslog buffers even more -- there - were cases where the outgoing relay= name was too long - to share a line with delay= and mailer= logging. - Limit the overhead on split envelopes to one open file descriptor - per envelope -- previously the overhead was three - descriptors. This was in response to a problem reported - by P{r (Pell) Emanuelsson. - Fixes to better handle the case of unexpected connection closes; - this redirects the output to the transcript so the info - is not lost. From Eric Wassenaar. - Fix potential string overrun if you macro evaluate a string that - has a naked $ at the end. Problem noted by James Matheson - . - Make default error number on $#error messages 553 (``Requested - action not taken: mailbox name not allowed'') instead of - 501 (``Syntax error in parameters or arguments'') to - avoid bogus "protocol error" messages. - Strip off any existing trailing dot on names during $[ ... $] - lookup. This prevents it from ending up with two dots - on the end of dot terminated names. From Wesley Craig - of the University of Michigan and Bryan Costales of ICSI. - Clean up file class reading so that the debugging information is - more informative. It hadn't been using setclass, so you - didn't see the class items being added. - Avoid core dump if you are running a version of sendmail where - NIS is compiled in, and you specify an NIS map, but - NIS is not running. Fix from John Oleynick of - Rutgers. - Diagnose bizarre case where res_search returns a failure value, - but sets h_errno to a success value. - Make sure that "too many hops" messages are considered important - enough to send an error to the Postmaster (that is, the - address specified in the P option). This fix should - help problems that cause the df file to be left around - sometimes -- unfortunately, I can't seem to reproduce - the problem myself. - Avoid core dump (null pointer reference) on EXPN command; this - only occurred if your log level was set to 10 or higher - and the target account was an alias or had a .forward file. - Problem noted by Janne Himanka. - Avoid "denial of service" attacks by someone who is flooding your - SMTP port with bad commands by shutting the connection - after 25 bad commands are issued. From Kyle Jones of - UUNET. - Fix core dump on error messages with very long "to" buffers; - fmtmsg overflows the message buffer. Fixed by trimming - the to address to 203 characters. Problem reported by - John Oleynick. - Fix configuration for HASFLOCK -- there were some spots where - a #ifndef was incorrectly #ifdef. Pointed out by - George Baltz of the University of Maryland. - Fix a typo in savemail() that could cause the error message To: - lists to be incorrect in some places. From Motonori - Nakamura. - Fix a glitch that can cause duplicate error messages on split - envelopes where an address on one of the lists has a - name server failure. Fix from Voradesh Yenbut of the - University of Washington. - Fix possible bogus pointer reference on ESMTP parameters that - don't have an ``=value'' part. - CNAME loops caused an error message to be generated, but also - re-queued the message. Changed to just re-queue the - message (it's really hard to just bounce it because - of the weird way the name server works in the presence - of CNAME loops). Problem noted by James M.R.Matheson - of Cambridge University. - Avoid giving ``warning: foo owned process doing -bs'' messages - if they use ``MAIL FROM:'' where foo is their true - user name. Suggested by Andreas Stolcke of ICSI. - Change the NAMED_BIND compile flag to be a 0/1 flag so you can - override it easily in the Makefile -- that is, you can - turn it off using -DNAMED_BIND=0. - If a gethostbyname(...) of an address with a trailing dot fails, - try it without the trailing dot. This is because if - you have a version of gethostbyname() that falls back - to NIS or the /etc/hosts file it will fail to find - perfectly reasonable names that just don't happen to - be dot terminated in the hosts file. You don't want to - strip the dot first though because we're trying to ensure - that country names that match one of your subdomains get - a chance. - PRALIASES: fix bogus output on non-null-terminated strings. - From Bill Gianopoulos of Raytheon. - CONFIG: Avoid rewriting anything that matches $w to be $j. - This was in code intended to only catch the self-literal - address (that is, [1.2.3.4], where 1.2.3.4 is your - IP address), but the code was broken. However, it will - still do this if $M is defined; this is necessary to - get client configurations to work (sigh). Note that this - means that $M overrides :mailname entries in the user - database! Problem noted by Paul Southworth. - CONFIG: Fix definition of Solaris help file location. From - Steve Cliffe . - CONFIG: Fix bug that broke news.group.USENET mappings. - CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, - and USENET_MAILER_MAX to tweak the maximum message - size for various mailers. - CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] - instead of assuming that it is "inews" for consistency - with other mailers. From Michael Corrigan of UC San Diego. - CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, - qualify the address in the SMTP envelope as user@{relay|hub} - instead of user@$j. From Bill Wisner of The Well. - CONFIG: Fix route-addr syntax in nullrelay configuration set. - CONFIG: Don't turn off case mapping of user names in the local - mailer for IRIX. This was different than most every other - system. - CONFIG: Avoid infinite loops on certainly list:; syntaxes in - envelope. Noted by Thierry Besancon - . - CONFIG: Don't include -z by default on uux line -- most systems - don't want it set by default. Pointed out by Philippe - Michel of Thomson CSF. - CONFIG: Fix some bugs with mailertables -- for example, if your - host name was foo.bar.ray.com and you matched against - ".ray.com", the old implementation bound %1 to "bar" - instead of "foo.bar". Also, allow "." in the mailertable - to match anything -- essentially, take over SMART_HOST. - This also moves matching of explicit local host names - before the mailertable so they don't have to be special - cased in the mailertable data. Reported by Bill - Gianopoulos of Raytheon; the fix for the %1 binding - problem was contributed by Nicholas Comanos of the - University of Sydney. - CONFIG: Don't include "root" in class $=L (users to deliver - locally, even if a hub or relay exists) by default. - This is because of the known bug where definition of - both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore - both and deliver into the local mailbox. - CONFIG: Move up bitdomain and uudomain handling so that they - are done before .UUCP class matching; uudomain was - reported as ineffective before. This also frees up - diversion 8 for future use. Problem reported by Kimmo - Suominen. - CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) - into host names. As pointed out by Jonathan Kamens, - these are often used because either the forward or reverse - mapping is broken; this translation makes it broken again. - DOC: Clarify $@ and $: in the Install & Op Guide.

From - Bob Campbell at U.C. Berkeley. - Security fix: group ids were not completely set when programs - were invoked. This caused programs to have group - permissions they should not have had (usually group - daemon instead of their own group). In particular, - Perl scripts would refuse to run. - Security: check to make sure files that are written are not - symbolic links (at least under some circumstances). - Although this does not respond to a specific known - attack, it's just a good idea. Suggested by - Christian Wettergren. - Security fix: if a user had an NFS mounted home directory on - a system with a restricted shell listed in their - /etc/passwd entry, they could still execute any - program by putting that in their .forward file. - This fix prevents that by insisting that their shell - appear in /etc/shells before allowing a .forward to - execute a program or write a file. You can disable - this by putting "*" in /etc/shells. It also won't - permit world-writable :include: files to reference - programs or files (there's no way to disable this). - These behaviours are only one level deep -- for - example, it is legal for a world-writable :include: - file to reference an alias that writes a file, on - the assumption that the alias file is well controlled. - Security fix: root was not treated suspiciously enough when - looking into subdirectories. This would potentially - allow a cracker to examine files that were publically - readable but in a non-publically searchable directory. - Fix a problem that causes an error on QUIT on a cached - connection to create problems on the current job. - These are typically unrelated, so errors occur in - the wrong place. - Reset CurrentLA in sendall() -- this makes sendmail queue - runs more responsive to load average, and fixes a - problem that ignored the load average in locally - generated mail. From Eric Wassenaar. - Fix possible core dump on aliases with null LHS. From - John Orthoefer of BB&N. - Revert to using flock() whenever possible -- there are just - too many bugs in fcntl() locking, particularly over - NFS, that cause sendmail to fail in perverse ways. - Fix a bug that causes the connection cache to get confused - when sending error messages. This resulted in - "unexpected close" messages. It should fix itself - on the following queue run. Problem noted by - Liudvikas Bukys of the University of Rochester. - Include $k in $=k as documented in the Install & Op Guide. - This seems odd, but it was documented.... From - Michael Corrigan of UCSD. - Fix problem that caused :include:s from alias files to be - forced to be owned by root instead of daemon - (actually DefUid). From Tim Irvin. - Diagnose unrecognized I option values -- from Mortin Forssen - of the Chalmers University of Technology. - Make "error" mailer work consistently when there is no error - code associated with it -- previously it returned OK - even though there was a real problem. Now it assumes - EX_UNAVAILABLE. - Fix bug that caused the last header line of messages that had - no body and which were terminated with EOF instead of - "." to be discarded. Problem noted by Liudvikas Bukys. - Fix core dump on SMTP mail to programs that failed -- it tried - to go to a "next MX host" when none existed, causing - a core dump. From der Mouse at McGill University. - Change IDENTPROTO from a defined/not defined to a 0/1 switch; - this makes it easier to turn it off (using - -DIDENTPROTO=0 in the Makefile). From der Mouse. - Fix YP_MASTER_NAME store to use the unupdated result of - gethostname() (instead of myhostname(), which tries - to fully qualify the name) to be consistent with - SunOS. If your hostname is unqualified, this fixes - transfers to slave servers. Bug noted by Keith - McMillan of Ameritech Services, Inc. - Fix Ultrix problem: gethostbyname() can return a very large - (> 500) h_length field, which causes the sockaddr - to be trashed. Use the size of the sockaddr instead. - Fix from Bob Manson of Ohio State. - Don't assume "-a." on host lookups if NAMED_BIND is not - defined -- this confuses gethostbyname on hosts - file lookups, which doesn't understand the trailing - dot convention. - Log SMTP server subprocesses that die with a signal instead - of from a clean exit. - If you don't have option "I" set, don't assume that a DNS - "host unknown" message is authoritative -- it - might still be found in /etc/hosts. - Fix a problem that would cause Deferred: messages to be sent - as the subject of an error message, even though the - actual cause of a message was more severe than that. - Problem noted by Chris Seabrook of OSSI. - Fix race condition in DBM alias file locking. From Kyle - Jones of UUNET. - Limit delivery syslog line length to avoid bugs in some - versions of syslog(3). This adds a new compile time - variable SYSLOG_BUFSIZE. From Jay Plett of Princeton - University, which is in turn derived from IDA. - Fix quotes inside of comments in addresses -- previously - it insisted that they be balanced, but the 822 spec - says that they should be ignored. - Dump open file state to syslog upon receiving SIGUSR1 (for - debugging). This also evaluates ruleset 89, if set - (with the null input), and logs the result. This - should be used sparingly, since the rewrite process - is not reentrant. - Change -qI, -qR, and -qS flags to be case-insensitive as - documented in the Bat Book. - If the mailer returned EX_IOERR or EX_OSERR, sendmail did not - return an error message and did not requeue the message. - Fix based on code from Roland Dirlewanger of - Reseau Regional Aquarel, Bordeaux, France. - Fix a problem that caused a seg fault if you got a 421 error - code during some parts of connection initialization. - I've only seen this when talking to buggy mailers on - the other end, but it shouldn't give a seg fault in - any case. From Amir Plivatsky. - Fix core dump caused by a ruleset call that returns null. - Fix from Bryan Costales of ICSI. - Full-Name: field was being ignored. Fix from Motonori Nakamura - of Kyoto University. - Fix a possible problem with very long input lines in setproctitle. - From P{r Emanuelsson. - Avoid putting "This is a warning message" out on return receipts. - Suggested by Douglas Anderson. - Detect loops caused by recursive ruleset calls. Suggested by - Bryan Costales. - Initialize non-alias maps during alias rebuilds -- they may be - needed for parsing. Problem noted by Douglas Anderson. - Log sender address even if no message was collected in SMTP - (e.g., if all RCPTs failed). Suggested by Motonori - Nakamura. - Don't reflect the owner-list contents into the envelope sender - address if the value contains ", :, /, or | (to avoid - illegal addresses appearing there). - Efficiency hack for toktype macro -- from Craig Partridge of - BB&N. - Clean up DNS error printing so that a host name is always - included. - Remember to set $i during queue runs. Reported by Stephen - Campbell of Dartmouth University. - If the environment variable HOSTALIASES is set, use it during - canonification as the name of a file with per-user host - translations so that headers are properly mapped. Reported - by Anne Bennett of Concordia University. - Avoid printing misleading error message if SMTP mailer (not - using [IPC]) should die on a core dump. - Avoid incorrect diagnosis of "file 1 closed" when it is caused - by the other end closing the connection. From - Dave Morrison of Oracle. - Improve several of the error messages printed by "mailq" - to include a host name or other useful information. - Add NetInfo preliminary support for NeXT systems. From Vince - DeMarco. - Fix a glitch that sometimes caused :include:s that pointed to - NFS filesystems that were down to give an "aliasing/ - forwarding loop broken" message instead of queueing - the message for retry. Noted by William C Fenner of - the NRL Connection Machine Facility. - Fix a problem that could cause a core dump if the input sequence - had (or somehow acquired) a \231 character. - Make sure that route-addrs always have around - them in non-SMTP envelopes (SMTP envelopes already do - this properly). - Avoid weird headers on unbalanced punctuation of the form: - ``Joe User ; this - has uucp-dom semantics but old UUCP syntax. This - also permits "uucp-old" as an alias for "uucp" and - "uucp-new" as a synonym for "suucp" for consistency. - CONFIG: add POP mailer support (from Kimmo Suominen - ). - CONFIG: drop CSNET_RELAY support -- CSNET is long gone. - CONFIG: fix bug caused with domain literal addresses (e.g., - ``[128.32.131.12]'') when FEATURE(allmasquerade) - was set; it would get an additional @masquerade.host - added to the address. Problem noted by Peter Wan - of Georgia Tech. - CONFIG: make sure that the local UUCP name is in $=w. From - Jim Murray of Stratus. - CONFIG: changes to UUCP rewriting to simulate IDA-style "V" - mailer flag. Briefly, if you are sending to host - "foo", then it rewrites "foo!...!baz" to "...!baz", - "foo!baz" remains "foo!baz", and anything else has - the local name prepended. - CONFIG: portability fixes for HP-UX. - DOC: several minor problems fixed in the Install & Op Guide. - MAKEMAP: fix core dump problem on lines that are too long or - which lack newline. From Mark Delany. - MAILSTATS: print sums of columns (total messages & kbytes - in and out of the system). From Tom Ferrin of UC - San Francisco Computer Graphics Lab. - SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: - On HP-UX, /etc/sendmail.cf has been moved to - /usr/lib/sendmail.cf to match HP sendmail. - Permissions have been tightened up on world-writable - :include: files and accounts that have shells - that are not listed in /etc/shells. This may - cause some .forward files that have worked - before to start failing. - SIGUSR1 dumps some state to the log. - NEW FILES: - src/Makefile.DGUX - src/Makefile.Dynix - src/Makefile.FreeBSD - src/Makefile.Mach386 - src/Makefile.NetBSD - src/Makefile.RISCos - src/Makefile.SCO - src/Makefile.SVR4 - src/Makefile.Titan - cf/mailer/pop.m4 - cf/ostype/bsdi1.0.m4 - cf/ostype/dgux.m4 - cf/ostype/dynix3.2.m4 - cf/ostype/sco3.2.m4 - makemap/Makefile.dist - praliases/Makefile.dist - -8.6.4/8.6.4 93/10/31 - Repair core-dump problem (write to read-only memory segment) - if you fall back to the return-to-Postmaster case in - savemail. Problem reported by Richard Liu. - Immediately diagnose bogus sender addresses in SMTP. This - makes quite certain that crackers can't use this - class of attack. - Reliability Fix: check return value from fclose() and fsync() - in a few critical places. - Minor problem in initsys() that reversed a condition for - redirecting the output channel on queue runs. It's - not clear this code even does anything. From Eric - Wassenaar of the Dutch National Institute for Nuclear - and High-Energy Physics. - Fix some problems that caused queue runs to do "too much work", - such as double-reading the Errors-To: header. From - Eric Wassenaar. - Error messages on writing the temporary file (including the - data file) were getting suppressed in SMTP -- this - fix causes them to be properly reported. From Eric - Wassenaar. - Some changes to support AF_UNIX sockets -- this will only - really become relevant in the next release, but some - people need it for local patches. From Michael - Corrigan of UC San Diego. - Use dynamically allocated memory (instead of static buffers) - for macros defined in initsys() and settime(); since - these can have different values depending on which - envelope they are in. From Eric Wassenaar. - Improve logging to show ctladdr on to= logging; this tells you - what uid/gid processes ran as. - Fix a problem that caused error messages to be discarded if - the sender address was unparseable for some reason; - this was supposed to fall back to the "return to - postmaster" case. - Improve aliaswait backoff algorithm. - Portability patches for Linux (8.6.3 required another header - file) (from Karl London) and SCO UNIX. - CONFIG: patch prog mailer to not strip host name off of envelope - addresses (so that it matches local again). From - Christopher Davis. - CONFIG: change uucp-dom mailer so that "<>" translates to $n; - this prevents uux from seeing lines with null names like - ``From Sat Oct 30 14:55:31 1993''. From Motonori - Nakamura of Kyoto University. - CONFIG: handle syntax correctly. This isn't legal, but - it shouldn't fail miserably. From Motonori Nakamura. - -8.6.2/8.6.2 93/10/15 - Put a "successful delivery" message in the transcript for - addresses that get return-receipts. - Put a prominent "this is only a warning" message in warning - messages -- some people don't read carefully enough - and end up sending the message several times. - Include reason for temporary failure in the "warning" return - message. Currently, it just says "cannot send for - four hours". - Fix the "Original message received" time generated for - returntosender messages. It was previously listed as - the current time. Bug reported by Eric Hagberg of - Cornell University Medical College. - If there is an error when writing the body of a message, - don't send the trailing dot and wait for a response - in sender SMTP, as this could cause the connection to - hang up under some bizarre circumstances. From Eric - Wassenaar. - Fix some server SMTP synchronization problems caused when - connections fail during message collection. From - Eric Wassenaar. - Fix a problem that can cause srvrsmtp to reject mail if the - name server is down -- it accepts the RCPT but rejects - the DATA command. Problem reported by Jim Murray of - Stratus. - Fix a problem that can cause core dumps if the config file - incorrectly resolves to a null hostname. Reported by - Allan Johannesen of WPI. - Non-root use of -C flag, dangerous -f flags, and use of -oQ - by non-root users were not put into - X-Authentication-Warning:s as intended because the - config file hadn't set the PrivacyFlags yet. Fix - from Sven-Ove Westberg of the University of Lulea. - Under very odd circumstances, the alias file rebuild code - could get confused as to whether a database was - open or not. - Check "vendor code" on the end of V lines -- this is - intended to provide a hook for vendor-specific - configuration syntax. (This is a "new feature", - but I've made an exception to my rule in a belief - that this is a highly exceptional case.) - Portability fixes for DG/UX (from Douglas Anderson of NCSC), - SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 - (from Jon Forrest of UC Berkeley) - CONFIG: fix ``mailer:host'' form of UUCP relay naming. - -8.6.1/8.6 93/10/08 - Portability fixes for A/UX and Encore UMAX V. - Fix error message handling -- if you had a name server down - causing an error during parsing, that message was never - propogated to the queue file. - -8.6/8.6 93/10/05 - Configuration cleanup: make it easier to undo IDENTPROTO in - conf.h (other systems have the same bug). - If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume - getdtablesize() instead of sysconf(); a disturbingly - large number of systems defined _SC_OPEN_MAX in the - header files but don't have the syscall. - Another patch to really truly ignore MX records in getcanonname - if trymx == FALSE. - Fix problem that caused the "250 IAA25499 Message accepted for - delivery" message to be omitted if there was an error - in the header of the message (e.g., a bad Errors-To: - line). Pointed out by Michael Corrigan of UCSD. - Announce name of host we are chatting when we get errors; this - is an IDA-ism suggested by Christophe Wolfhugel. - Portability fixes for Alpha OSF/1 (from Anthony Baxter of the - Australian Artificial Intelligence Institute), SCO Unix - (from Murray Kucherawy of Hookup Communication Corp.), - NeXT (from Vince DeMarco and myself), Linux (from - Karl London ), BSDI (from - Christophe Wolfhugel, and SVR4 on Dell (from Kimmo - Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. - Some changes to get around gcc optimizer bugs. From Takahiro - Kanbe. - Fix error recovery in queueup if another tf file of the same - name already exists. Problem stumbled over by Bill - Wisner of The Well. - Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. - Problem noted by Keith McMillan of Ameritech Services. - Deal with group permissions properly when opening .forward and - :include: files. This relaxes the 8.1C restrictions - slightly more. This includes proper setting of groups - when reading :include: files, allowing you to read some - files that you should be able to read but have previously - been denied unless you owned them or they had "other" - read permission. - Make certain that $j is in $=w (after the .cf is read) so that - if the user is forced to override some silly system, - MX suppression will still work. - Fix a couple of efficiency problems where newstr was double- - calling expensive routines. In at least one case, it - wasn't guaranteed that they would always return the - same result. Problem noted by Christophe Wolfhugel. - Fix null pointer dereference in putoutmsg -- only on an error - condition from a non-SMTP mailer. From Motonori - Nakamura. - Macro expand "C" line class definitions before scanning so that - "CX $Z" works. - Fix problem that caused error message to be sent while still - trying to send the original message if the connection - is closed during a DATA command after getting an error - on an RCPT command (pretty obscure). Problem reported - by John Myers of CMU. - Fix reply to NOOP to be 250 instead of 200 -- this is a long - term bug. - Fix a nasty bug causing core dumps when returning the "warning: - cannot deliver for N hours -- will keep trying" message; - it only occurred if you had PostMasterCopy set and - only on some architectures. Although sendmail would - keep trying, it would send error messages on each - queue interval. This is an important fix. - Allow u and g options to take user and group names respectively. - Don't do a chdir into the queue directory in -bt mode to make - ruleset testing a bit easier. - Don't allow users to turn off logging (using -oL) on the command - line -- command line can only raise, not lower, logging - level. - Set $u to the original recipient on the SMTP transaction or on - the command line. This is only done if there is exactly - one recipient. Technically, this does not meet the - specs, because it does not guarantee a domain on the - address. - Fix a problem that dumped error messages on bad addresses if - you used the -t flag. Problem noted by Josh Smith of - Harvey Mudd College. - Given an address such as `` '', auto-quote the first - ``'' part, giving ``"" ''. This is to - avoid the problem of people who use angle brackets in - their full name information. - Fix a null pointer dereference if you set option "l", have - an Errors-To: header in the message, and have Errors-To: - defined in the config file H lines. From J.R. Oldroyd. - Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get - wrong when compiling. Suggested by Rick McCarty of TI. - Fix a problem that could pass negative SIZE parameter if the - df file got lost; this would cause servers to always - give a temporary failure, making the problem even worse. - Problem noted by Allan Johannesen of WPI. - Add "ident" timeout (one of the "r" option selectors) for IDENT - protocol timeouts (30s default). Requested by Murray - Kucherawy of HookUp Communication Corp. to handle bogus - PC TCP/IP implementations. - Change $w default definition to be just the first component of - the domain name on config level 5. The $j macro defaults - to the FQDN; $m remains as before. This lets well-behaved - config files use any of the short, long, or subdomain - names. - Add makesendmail script in src to try to automate multi-architecture - builds. I know, this is sub-optimal, but it is still - helpful. - Fix very obscure race condition that can cause a queue run to - get a queue file for an already completed job. This - problem has existed for years. Problem noted by the - long suffering Allan Johannesen of WPI. - Fix a problem that caused the raw sender name to be passed to - udbsender instead of the canonified name -- this caused - it to sometimes miss records that it should have found. - Relax check of name on HELO packet so that a program using -bs - that claims to be itself works properly. - Restore rewriting of $: part of address through 2, R, 4 in - buildaddr -- this requires passing a lot of flags to get - it right. Unlike old versions, this ONLY rewrites - recipient addresses, not sender addresses. - Fix a bug that caused core dumps in config files that cannot - resolve /file/name style addresses. Fix from Jonathan - Kamens of OpenVision Technologies. - Fix problem with fcntl locking that can cause error returns to - be lost if the lock is lost; this required fully - queueing everything, dropping the envelope (so errors - would get returned), and then re-reading the queue from - scratch. - Fix a problem that caused aliases that redefine an otherwise - true address to still send to the original address - if and only if the alias failed in certain bizarre - ways (e.g, if they pointed at a list:; syntax address). - Problem pointed out by Jonathan Kamens. - Remove support for frozen configuration files. They caused - more trouble than it was worth. - Fix problem that can cause error messages to get ignored when - using both -odb and -t flags. Problem noted by Rob - McNicholas at U.C. Berkeley. - Include all "normal" variations on hostname in $=w. For example, - if the host name is vangogh.cs.berkeley.edu, $=w will - contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. - Add "restrictqrun" privacy flag -- without this, anyone can run - the queue. - Reset SmtpPhase global on initial connection creation so that - messages don't come out with stale information. - Pass an "ext" argument to lockfile so that error/log messages - will properly reflect the true filename being locked. - Put all [...] address forms into $=w -- this eliminates the need - for MAXIPADDR in conf.h. Suggested by John Gardiner - Myers of CMU. - Fix a bug that can cause qf files to be left around even after - an SMTP RSET command. Problem and fix from Michael - Corrigan. - Don't send a PostMasterCopy to errors when the Precedence: is - negative. Error reports still go to the envelope - sender address. - Add LA_SHORT for load averages. - Lock sendmail.st file when posting statistics. - Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to - set the size of the TCP send and receive buffers; if you - run over a slow slip line you may need to set these down - (although it would be better to fix the SLIP implementation - so that it's not necessary to recompile every program - that does bulk data transfer). - Allow null defaults on $( ... $) lookups. Problem reported by - Amir Plivatsky. - Diagnose crufty S and V config lines. This resulted from an - observation that some people were using the SITE macro - without the SITECONFIG macro first, which was causing - bogus config files that were not caught. - Fix makemap -f flag to turn off case folding (it was turning it - on instead). THIS IS A USER VISIBLE CHANGE!!! - Fix a problem that caused multiple error messages to be sent if - you used "sendmail -t -oem -odb", your system uses fcntl - locking, and one of the recipient addresses is unknown. - Reset uid earlier in include() so that recursive .forwards or - :include:s don't use the wrong uid. - If file descriptor 0, 1, or 2 was closed when sendmail was - called, the code to recover the descriptor was broken. - This sometimes (only sometimes) caused problems with the - alias file. Fix from Motonori Nakamura. - Fix a problem that caused aliaswait to go into infinite recursion - if the @:@ metasymbol wasn't found in the alias file. - Improve error message on newaliases if database files cannot be - opened or if running with no database format defined. - Do a better estimation of the size of error messages when NoReturn - is set. Problem noted by P{r (Pell) Emanuelsson. - Fix a problem causing the "c" option (don't connect to expensive - mailers) to be ignored in SMTP. Problem noted and the - solution suggested by Robert Elz of The University of - Melbourne. - Improve connection caching algorithm by passing "[host]" to - hostsignature, which strips the square brackets and - returns the real name. This allows mailertable entries - to match regular entries. - Re-enable Return-Receipt-To: -- people seem to want this stupid - feature, even if it doesn't work right. - Catch and log attempts to try the "wiz" command in server SMTP. - This also ups the log level from LOG_NOTICE to LOG_CRIT. - Be more generous at assigning $z to the home directory -- do this - for programs that are specified through a .forward file. - Fix from Andrew Chang of Sun Microsystems. - Always save a fatal error message in preference to a non-fatal - error message so that the "subject" line of return - messages is the best possible. - CONFIG: reduce the number of quotes needed to quote configuration - parameters with commas: two quotes should work now, e.g., - define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). - CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom - connections (domain-ized UUCP). - CONFIG: fix bug in default maps (-o must be before database file - name). Pointed out by Christophe Wolfhugel. - CONFIG: add FEATURE(nodns) to state that we are not relying on - DNS. This would presumably be used in UUCP islands. - CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). - CONFIG: log $u in Received: line. This is in technical violation - of the standards, since it doesn't guarantee a domain - on the address. - CONFIG: don't assume "m" in local mailer flags -- this means that - if you redefine LOCAL_MAILER_FLAGS you will have to include - the "m" flag should you want it. Apparently some Solaris 2.2 - installations can't handle multiple local recipients. - Problem noted by Josh Smith. - CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). - CONFIG: change default version level from 4 to 5. - CONFIG: add FEATURE(nullclient) to create a config file that - forwards all mail to a hub without ever looking at the - addresses in any detail. - CONFIG: properly strip mailer: information off of relays when - used to change .BITNET form into %-hack form. - CONFIG: fix a problem that caused infinite loops if presented - with an address such as "!foo". - CONFIG: check for self literal (e.g., [128.32.131.12]) even if - the reverse "PTR" mapping is broken. There's a better - way to do this, but the change is fairly major and I - want to hold it for another release. Problem noted by - Bret Marquis. - -8.5/8.5 93/07/23 - Serious bug: if you used a command line recipient that was unknown - sendmail would not send a return message (it was treating - everything as though it had an SMTP-style client that - would do the return itself). Problem noted by Josh Smith. - Change "trymx" option in getcanonname() to ignore all MX data, - even during a T_ANY query. This actually didn't break - anything, because the only time you called getcanonname - with !trymx was if you already knew there were no MX - records, but it is somewhat cleaner. From Motonori - Nakamura. - Don't call getcanonname from getmxrr if you already know there - are no DNS records matching the name. - Fix a problem causing error messages to always include "The - original message was received ... from localhost". - The correct original host information is now included. - Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their - version of "test" doesn't have the -x flag). Change it - to use -f instead. From John Myers. - CONFIG: 8.4 mistakenly set the default SMTP-style mailer to - esmtp -- it should be smtp. - CONFIG: send all relayed mail using confRELAY_MAILER (defaults - to "relay" (a variant of "smtp") if MAILER(smtp) is used, - else "suucp" if MAILER(uucp) is used, else "unknown"); - this cleans up the configs somewhat. This fixes a serious - problem that caused route-addrs to get mistaken as relays, - pointed out by John Myers. WARNING: this also causes - the default on SMART_HOST to change from "suucp" to - "relay" if you have MAILER(smtp) specified. - -8.4/8.4 93/07/22 - Add option `w'. If you receive a message that comes to you because - you are the best (lowest preference) target of an MX, and - you haven't explicitly recognized the source MX host in - your .cf file, this option will cause you to try the target - host directly (as if there were no MX for it at all). If - `w' is not set, this case is a configuration error. - Beware: if `w' is set, senders may get bogus errors like - "message timed out" or "host unknown" for problems that - are really configuration errors. This option is - disrecommended, provided only for compatibility with - UIUC sendmail. - Fix a problem that caused the incoming socket to be left open - when sendmail forks after the DATA command. This caused - calling systems to wait in FIN_WAIT_2 state until the - entire list was processed and the child closed -- a - potentially prodigious amount of time. Problem noted - by Neil Rickert. - Fix problem (created in 6.64) that caused mail sent to multiple - addresses, one of which was a bad address, to completely - suppress the sending of the message. This changes - handling of EF_FATALERRS somewhat, and adds an - EF_GLOBALERRS flag. This also fixes a potential problem - with duplicate error messages if there is a syntax error - in the header of a message that isn't noticed until late - in processing. Original problem pointed out by Josh Smith - of Harvey Mudd College. This release includes quite a bit - of dickering with error handling (see below). - Back out SMTP transaction if MAIL gets nested 501 error. This - will only hurt already-broken software and should help - humans. - Fix a problem that broke aliases when neither NDBM nor NEWDB were - compiled in. It would never read the alias file. - Repair unbalanced `)' and `>' (the "open" versions are already - repaired). - Logging of "done" in dropenvelope() was incorrect: it would - log this even when the queue file still existed. Change - this to only log "done" (at log level 11) when the - queue file is actually removed. From John Myers. - Log "lost connection" in server SMTP at log level 20 if there - is no pending transaction. Some senders just close the - connection rather than sending QUIT. - Fix a bug causing getmxrr to add a dot to the end of unqualified - domains that do not have MX records -- this would cause - the subsequent host name lookup to fail. The problem - only occurred if you had FEATURE(nocanonify) set. - Problem noted by Rick McCarty of Texas Instruments. - Fix invocation of setvbuf when passed a -X flag -- I had - unwittingly used an ANSI C extension, and this caused - core dumps on some machines. - Diagnose self-destructive alias loops on RCPT as well as EXPN. - Previously it just gave an empty send queue, which - then gave either "Need RCPT (recipient)" at the DATA - (confusing, since you had given an RCPT command which - returned 250) or just dropped the email, depending on - whether you were running VERBose mode. Now it usually - diagnoses this case as "aliasing/forwarding loop broken". - Unfortunately, it still doesn't adequately diagnose - some true error conditions. - Add internal concept of "warning messages" using 6xx codes. - These are not reported only to Postmaster. Unbalanced - parens, brackets, and quotes are printed as 653 codes. - They are always mapped to 5xx codes before use in SMTP. - Clean up error messages to tell both the actual address that - failed and the alias they arose from. This makes it - somewhat easier to diagnose problems. Difficulty noted - by Motonori Nakamura. - Fix a problem that inappropriately added a ctladdr to addresses - that shouldn't have had one during a queue run. This - caused error messages to be handled differently during - a queue run than a direct run. - Don't print the qf name and line number if you get errors during - the direct run of the queue from srvrsmtp -- this was - just extra stuff for users to crawl through. - Put command line flags on second line of pid file so you can - auto-restart the daemon with all appropriate arguments. - Use "kill `head -1 /etc/sendmail.pid`" to stop the - daemon, and "eval `tail -1 /etc/sendmail.pid`" to - restart it. - Remove the ``setuid(getuid())'' in main -- this caused the - IDENT daemon to screw up. This required that I change - HASSETEUID to HASSETREUID and complicate the mode - changing somewhat because both Ultrix and SunOS seem - to have a bug causing seteuid() to set the saved uid - as well as the effective. The program test/t_setreuid.c - will test to see if your implementation of setreuid(2) - is appropriately functional. - The FallBackMX (option V) handling failed to properly identify - fallback to yourself -- most of the code was there, - but it wasn't being enabled. Problem noted by Murray - Kucherawy of the University of Waterloo. - Change :include: open timeout from ETIMEDOUT to an internal - code EOPENTIMEOUT; this avoids adding "during SmtpPhase - with CurHostName" in error messages, which can be - confusing. Reported by Jonathan Kamens of OpenVision - Technologies. - Back out setpgrp (setpgid on POSIX systems) call to reset the - process group id. The original fix was to get around - some problems with recalcitrant MUAs, but it breaks - any call from a shell that creates a process group id - different from the process id. I could try to fix - this by diddling the tty owner (using tcsetpgrp or - equivalent) but this is too likely to break other - things. - Portability changes: - Support -M as equivalent to -oM on Ultrix -- apparently - DECnet calls sendmail with -MrDECnet -Ms -bs - instead of using standard flags. Oh joy. This - behaviour reported by Jon Giltner of University - of Colorado. - SGI IRIX -- this includes several changes that should - help other strict ANSI compilers. - SCO Unix -- from Murray Kucherawy of HookUp Communication - Corporation. - Solaris running the Sun C compiler (which despite the - documentation apparently doesn't define - __STDC__ by default). - ConvexOS from Eric Schnoebelen of Convex. - Sony NEWS workstations and Omron LUNA workstations from - Motonori Nakamura. - CONFIG: add confTRY_NULL_MX_LIST to set option `w'. - CONFIG: delete `C' and `e' from default SMTP mailers flags; - several people have made a good argument that this - creates more problems than it solves (although this - may prove painful in the short run). - CONFIG: generalize all the relays to accept a "mailer:host" - format. - CONFIG: move local processing in ruleset 0 into a new ruleset - 98 (8 on old sendmail). Domain literal [a.b.c.d] - addresses are also passed through this ruleset. - CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, - internet-style addresses would "fall off the end" of - ruleset zero and be interpreted as local -- however, - the angle brackets confused the recursive call. - These are now diagnosed as "Unrecognized host name". - CONFIG: USENET rules weren't included in S0 because of a mistaken - ifdef(`_MAILER_USENET_') instead of - ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik - of SINTEF RUNIT, Oslo. - CONFIG: move up LOCAL_RULE_0 processing so that it happens very - early in ruleset 0; this allows .mc authors to bypass - things like the "short circuit" code for local addresses. - Prompted by a comment by Bill Wisner of The Well. - CONFIG: add confSMTP_MAILER to define the mailer used (smtp or - esmtp) to send SMTP mail. This allows you to default - to esmtp but use a mailertable or other override to - deal with broken servers. This logic was pointed out - to me by Bill Wisner. Ditto for confLOCAL_MAILER. - Changes to cf/sh/makeinfo.sh to make it portable to SVR4 - environments. Ugly as sin. - -8.3/8.3 93/07/13 - Fix setuid problems introduced in 8.2 that caused messages - like "Cannot create qfXXXXXX: Invalid argument" - or "Cannot reopen dfXXXXXX: Permission denied". This - involved a new compile flag "HASSETEUID" that takes - the place of the old _POSIX_SAVED_IDS -- it turns out - that the POSIX interface is broken enough to break - some systems badly. This includes some fixes for - HP-UX. Also fixes problems where the real uid is - not reset properly on startup (from Neil Rickert). - Fix a problem that caused timed out messages to not report the - addresses that timed out. Error messages are also more - "user friendly". - Drop required bandwidth on connections from 64 bytes/sec to - 16 bytes/sec. - Further Solaris portability changes -- doesn't require the BSD - compatibility library. This also adds a new - "HASGETDTABLESIZE" compile flag which can be used if - you want to use getdtablesize(2) instead of sysconf(2). - These are loosely based on changes from David Meyer at - University of Oregon. This now seems to work, at least - for quick test cases. - Fix a problem that can cause duplicate error messages to be - sent if you are in SMTP, you send to multiple addresses, - and at least one of those addresses is good and points - to an account that has a .forward file (whew!). - Fix a problem causing messages to be discarded if checkcompat() - returned EX_TEMPFAIL (because it didn't properly mark - the "to" address). Problem noted by John Myers. - Fix dfopen to return NULL if the open failed; I was depending - on fdopen(-1) returning NULL, which isn't the case. This - isn't serious, but does result in weird error diagnoses. - From Michael Corrigan. - CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of - messages sent through UUCP-family mailers. Suggested - by Bill Wisner of The Well. - CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, - include a "uucp-dom" mailer that uses domain-style - addressing. Suggested by Bill Wisner. - CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match - LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by - Christophe Wolfhugel. - CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. - -8.2/8.2 93/07/11 - Don't drop out on config file parse errors in -bt mode. - On older configuration files, assume option "l" (use Errors-To - header) for back compatibility. NOTE: this DOES NOT - imply an endorsement of the Errors-To: header in any way. - Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? - Don't log errors on EHLO -- it isn't a "real" error for an old - SMTP server to give an error on this command, and - logging it in the transcript can be confusing. Fix - from Bill Wisner. - IRIX compatibility changes provided by Dan Rich - . - Solaris 2 compatibility changes. Provided by Bob Cunningham - , John Oleynick - - Debugging: -d17 was overloaded (hostsignature and usersmtp.c); - move usersmtp (smtpinit and smtpmailfrom) to -d18 to - match the other flags in that file. - Flush transcript before fork in mailfile(). From Eric Wassenaar. - Save h_errno in mci struct and improve error message display. - Changes from Eric Wassenaar. - Open /dev/null for the transcript if the create of the xf file - failed; this avoids at least one possible null pointer - reference in very weird cases. From Eric Wassenaar. - Clean up statistics gathering; it was over-reporting because of - forks. From Eric Wassenaar. - Fix problem that causes old Return-Path: line to override new - Return-Path: line (conf.c needs H_FORCE to avoid - re-using old value). From Motonori Nakamura. - Fix broken -m flag in K definition -- even if -m (match only) - was specified, it would still replace the key with the - value. Noted by Rick McCarty of Texas Instruments. - If the name server timed out over several days, no "timed out" - message would ever be sent back. The timeout code - has been moved from markfailure() to dropenvelope() - so that all such failures should be diagnosted. Pointed - out by Christophe Wolfhugel and others. - Relax safefile() constraints: directories in an include or - forward path must be readable by self if the controlling - user owns the entry, readable by all otherwise (e.g., - when reading your .forward file, you have to own and - have X permssion in it; everyone needs X permission in - the root and directories leading up to your home); - include files must be readable by anyone, but need not - be owned by you. - If _POSIX_SAVED_IDS is defined, setuid to the owner before - reading a .forward file; this gets around some problems - on NFS mounts if root permission is not exported and - the user's home directory isn't x'able. - Additional NeXT portability enhancements from Axel Zinser. - Additional HP-UX portability enhancements from Brian Bullen. - Add a timeout around SMTP message writes; this assumes you can - get throughput of at least 64 bytes/second. Note that - this does not impact the "datafinal" default, which - is separate; this is just intended to work around - network clogs that will occur before the final dot - is sent. From Eric Wassenaar. - Change map code to set the "include null" flag adaptively -- - it initially tries both, but if it finds anything - matching without a null it never tries again with a - null and vice versa. If -N is specified, it never - tries without the null and creates new maps with a - null byte. If -O is specified, it never tries with - the null (for efficiency). If -N and -O are specified, - you get -NO (get it?) lookup at all, so this would - be a bad idea. If you don't specify either -N or -O, - it adapts. - Fix recognition of "same from address" so that MH submissions - will insert the appropriate full name information; - this used to work and got broken somewhere along the - way. - Some changes to eliminate some unnecessary SYSERRs in the - log. For example, if you lost a connection, don't - bother reporting that fact on the connection you lost. - Add some "extended debugging" flags to try to track down - why we get occassional problems with file descriptor - one being closed when execing a mailer; it seems to - only happen when there has been another error in the - same transaction. This requires XDEBUG, defined - by default in conf.h. - Add "-X filename" command line flag, which logs both sides of - all SMTP transactions. This is intended ONLY for - debugging bad implementations of other mailers; start - it up, send a message from a mailer that is failing, - and then kill it off and examine the indicated log. - This output is not intended to be particularly human - readable. This also adds the HASSETVBUF compile - flag, defaulted on if your compiler defines __STDC__. - CONFIG: change SMART_HOST to override an SMTP mailer. If you - have a local net that should get direct connects, you - will need to use LOCAL_NET_CONFIG to catch these hosts. - See cf/README for an example. - CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle - sites that don't use the -d flag. - CONFIG: hide recipient addresses as well as sender addresses - behind $M if FEATURE(allmasquerade) is specified; this - has been requested by several people, but can break - local aliases. For example, if you mail to "localalias" - this will be rewritten as "localalias@masqueradehost"; - although initial delivery will work, replies will be - broken. Use it sparingly. - CONFIG: add FEATURE(domaintable). This maps unqualified domains - to qualified domains in headers. I believe this is - largely equivalent to the IDA feature of the same name. - CONFIG: use $U as UUCP name instead of $k. This permits you - to override the "system name" as your UUCP name -- - in particular, to use domain-ized UUCP names. From - Bill Wisner of The Well. - CONFIG: create new mailer "esmtp" that always tries EHLO - first. This is currently unused in the config files, - but could be used in a mailertable entry. - -8.1C/8.1B 93/06/27 - Serious security bug fix: it was possible to read any file on - the system, regardless of ownership and permissions. - If a subroutine returns a fully qualified address, return it - immediately instead of feeding it back into rewriting. - This fixes a problem with mailertable lookups. - CONFIG: fix some M4 frotz (concat => CONCAT) - -8.1B/8.1A 93/06/12 - Serious bug fix: pattern matching backup algorithm stepped by - two tokens in classes instead of one. Found by Claus - Assmann at University of Kiel, Germany. - -8.1A/8.1A 93/06/08 - Another mailertable fix.... - -8.1/8.1 93/06/07 - 4.4BSD freeze. No semantic changes. - -6.65/6.34 93/06/06 - Fix some lintish problems. - Fix some cases where server SMTP behaved poorly when handed bogus - input, pointed out by Eric Wassenaar. - CONFIG: fix some more (sigh) mailertable bugs -- thanks to - Motonori Nakamura of Kyoto University (again). - -6.64/6.33 93/06/05 - Don't send 050 (-v) information after the 250 response to a QUIT - command in srvrsmtp -- clients usually close the connection - at this point, and it causes bogus error messages. - Don't send messages that have errors on input (such as unbalanced - parentheses) during SMTP transactions, since a return - message has (probably) already been sent. - Give better diagnostics on timeouts during network reads, including - information similar to the SMTP phase. - Fix bug that caused SMTP messages to deliver synchronously; this - happened after the DATA 250, and hence caused reading the - next command to be delayed. - Ignore Errors-To: header unless 'l' (lower case el) header is - specified. The Errors-To: header violates RFC 1123. - Errors-To: was only needed to take the place of the - envelope sender in the days when most Unix mailers - didn't understand about the two kinds of senders. - Don't send warning messages in response to automatically generated - messages (that is, those From:<>). - CONFIG: fix some rather stupid typos in the mailertable code - pointed out by Motonori Nakamura of Kyoto University. - CONFIG: add confUSE_ERRORS_TO configuration option. - CONFIG: if ALWAYS_ADD_DOMAIN is selected, try to use $M - (masquerade name) instead of $j. - CONFIG: don't add dots to relay names (added in 6.29); it breaks - several things, and can be simulated by dot terminating - the names of relays. For example, use: - DBbit.net.relay. - (note the trailing dot). - -6.63/6.32 93/06/01 - Fix prototypes to eliminate chars in argument lists -- some - compilers are pissy about this. - Log protocol ($r) and body type if set so we can determine if - the adaptive algorithms are working. - Pessimize on locking of database files (particularly for NEWDB - databases) during opens. There were problems with - processes opening the file while it was rebuilt; since - NEWDB caches heavily, the reader opened an empty file, - which is an error. If your system has the ability to - lock atomically on open, this works properly; otherwise, - there are race conditions. - Check mod time on .pag file instead of .dir in NDBM aliases - because the .dir file doesn't get updated for small - alias files. From John Gardiner Myers of CMU. - More Solaris portability -- it now compiles on Solaris, but - hangs up in gethostbyname(). - Move setting of RES_DEBUG flag before first myhostname() call - so we can see name server traffic on that call. - Fsync() queue files. - Fix a problem that causes -bi to try to rebuild maps other than - the alias file(s). - Fix a problem that caused udb to reject entries from any but - the first database listed. - Rearrange doc subdirectory for 4.4BSD release tape. - CONFIG: put $r into the Received line. This was an oversight. - CONFIG: fix typo (call to ruleset 99 should have been rulset 90). - CONFIG: move "auxiliary" subroutines to be in ruleset 90-99 - range -- in the long run, single digit rulesets may - become reserved for builtin use by sendmail. - CONFIG: fix major problem that causes host aliases (that is, - anything in $=w != $j) to not be recognized. This has - been around since 6.30. - -6.62/6.31 93/05/28 - BETA RELEASE - Fix recursive syserr (if there is an error printing a syserr - message). This makes the code much less eager to consider - a write error as serious. This also includes some - heuristics to be clever about closed connections. - Lock NEWDB files during gets. This requires version 1.5 or later - of the db library. If you have an older version, you - can use -DOLD_NEWDB. This will go away in a few weeks. - Fix problem causing aliases that use host maps to get overwritten. - Do appropriate byte swapping on port numbers in ident protocol - code. Fix from Allan Johannesen of WPI. - Defer opening of map files to the same time as alias files so that - the daemon will tend to pick up new versions more promptly. - Prototype a bunch more functions. - Some Solaris 2.1 changes (still doesn't link though). - Try to simplify Makefiles by including more subordinate #defines - in conf.h (based on OS type). - CONFIG: check for domains if FEATURE(mailertable) is defined. - For example, if the host name is "knecht.cs.berkeley.edu" - it will search the following mailertable keys: - knecht.cs.berkeley.edu - .cs.berkeley.edu - .berkeley.edu - .edu - This could be used to replace the special relays for bitnet - and similar nets. - -6.61/6.30 93/05/24 - Fix problem that prevented appending dots on canonified host - names. This breaks tons of config files -- very - important fix. - Fix improper pointer dereference in response to HELO command. - Fix core dump if debugging set in map_rewrite. - CONFIG: add FEATURE(always_add_domain) to always attach the - local domain (only impacts local mail). - CONFIG: try to avoid turning names into $j -- although - technically a host can only have one "canonical name", - it seems to be common practice to have several. - -6.60/6.29 93/05/22 - Major change: merge alias databases with maps. This expands and - changes the map class interface but fixes a bunch of bugs. - The important user-visible change is that the file name - in a K line now does not include the ".db" extension; this - is added automatically. Also, the -d (NIS domain) flag is - missing from the K config line; use @domain instead. - When compiling, the *_MAP names are gone -- just compile - in NDBM, NEWDB, and/or NIS support. - Announce mailer/host/user triple on -bv flag -- from Brian - Bullen of Stirling University. - Don't send more than one line in response to HELO -- it confuses - Pony Express, which then behaves very badly. However, - this change does send two line 220 greetings, with the - second line reading "ESMTP spoken here". The usersmtp - module recognizes this and goes into ESMTP mode regardless - of the setting of the "a" mailer flag. Thus, "a" means - "always try EHLO". - AIX portability changes (thanks to Christophe Wolfhugel of - Herve Schauer Consultants (Paris) for providing me with - an INSA account for this purpose). Lightly tested. Use - -D_AIX3. This probably breaks compatibility with some - older systems (e.g., 4.2bsd) but still works on SunOS - 4.1.2, Ultrix 4.2A, HP-UX 8.07, OSF/1 T1.3, and AIX 3.2.3. - Fix a problem causing an error message loop if the output channel - is hosed. - Add the Makefiles that I use for various environments -- some are - Berkeley make versions and some are old make versions. - My makefile for the NeXT box has gotten lost, alas! - PRALIASES: support for printing NEWDB databases. From - Michael J. Corrigan of U.C. San Diego. - CONFIG: don't pass pseudo-domains to $[ ... $] (if you have - a wildcard MX it can have weird results). From - Christophe Wolfhugel. - CONFIG: dot terminate relay hostnames in S0. From Christophe - Wolfhugel. - -6.59/6.28 93/05/13 - Log version with SMTP daemon startup message. - Adjust setproctitle to work on NetBSD and BSD/386. - Fix null pointer reference in MX fallback code. - A bunch of minor fixes from Eric Wassenaar: - If deliver cannot execv the mailer, return EX_OSERR - instead of EX_TEMPFAIL (to give better - error messages). - Consistently malloc e_message. - Catch degenerate case of calling returntosender() - with an empty returnq. - MIME reformatting. - -6.58/6.28 93/05/13 - Fix bug that can cause incorrect verbose display of user smtp - messages. - Disable SMTP VERB command if PRIV_NOEXPN is set (since this - could reveal the same information. - Allow failure when reading SMTP greeting message to go on to - next MX host. - Add "MIME-Version: 1.0" header if using MIME (this was NOT - included in RFC 1344, but Bill King of Allan-Bradley - Company forwarded me email from Nathaniel Borenstein - claiming that it was an inadvertent omission). - Don't use Content-Type: X-message-header. According to John - Myers of CMU, many MIME readers will completely ignore - the data if they don't recognize it. Instead, just - add a blank line to make it a legal (empty) message. - Fix problem causing dots to keep getting appended to cached - hostnames. This can cause buffer overrun conditions. - The problem was found by Erik Forsberg of Retix, - although I used a different bug fix than he provided. - Fix parsing of split header/envelope rewriting specs -- from - Eric Forsberg. - Fix from Eric Wassenaar to correct To: lists in error messages. - -6.57/6.28 93/05/11 - Fix minor glitch causing extra ctladdrs to be output to queue - file. Just an annoyance. - Cache results of name server canonification lookups to avoid - backed up queue runs. - Major rewrite of alias.c: considerable cleanup, plus sample - (untested) support for NIS aliases. The "A" option - can now be a comma separated list (or be repeated) -- - that is, you can have multiple alias databases. Each - database can have the syntax ``class:file''; if no class - is specified, the "implicit" class is assumed. Implicit - searches through a list of compiled in types -- hash, - dbm, nis, and stab. Alias files are searched in the - order they are listed. For example: - OAhash:/etc/aliases.local,/etc/aliases - OAnis:mail.aliases@my.nis.domain - first searches the hash database /etc/aliases.local, - then the regular /etc/aliases database, then the NIS - map "mail.aliases" in the NIS domain "my.nis.domain". - If in Verbose mode (probably from VERB command) run SMTP job - in foreground and don't do RCPT optimizations. - Add udb :mailsender as equivalent to owner- for regular aliases. - Delete option 8; add option 7 that means the opposite. That is, - default to 8-bit mode; a special option is needed to - force sendmail into 7 bit mode. - Send error messages in encapsulated MIME format. - New compile flag "NIS" that turns on NIS alias and NIS map - support. - Add "j" option to send error messages in MIME (RFC 1341) - encapsulated message format per RFC 1344. The - syntax is pretty ugly if you don't have MIME-aware - user agents. - Clean up message handling (for display in mailq output). - New setproctitle implementation for 4.4bsd. - Create files (such as ~/dead.letter) using mode FileMode (the - F option value) instead of 0666. - Fix bug causing output of EXPN command to not be fully qualified. - This may cause some problems with UUCP addresses that - will require some config file assistance -- specifically, - the $: part has to include the host name for this output - to make sense. - Fix a problem that sometimes diagnosed errors and still sent the - message if the header syntax was bad. - Fix a bug that caused an error message to be emailed when sendmail - was operating in -bv mode. - Add "ListenQueueSize" keyword to daemon options option (OO) to - set the queue size parameter passed to listen(). You - will normally have to tweak your kernel to up this. - Strip spaces off of beginning of message-id before logging (in - case it was folded across lines). - Tweak compile flags in daemon.c -- there were some cases where - it wouldn't work without NETINET. - Change *file* mailer to output all the usual default headers - (From, Date, Message-Id). It gets used when sending - back error messages. - CONFIG: explicitly catch and diagnose list:; syntax in ruleset - zero -- this is not a valid recipient syntax according - to RFC 821. - CONFIG: add confMIME_FORMAT_ERRORS to send error messages in - MIME format. Defaults to on. - CONFIG: add SMTP_MAILER_FLAGS and UUCP_MAILER_FLAGS to augment - the flags for those mailers. - -6.56/6.27 93/05/01 - Fix problem that causes the fallback mail to postmaster - (case ESM_POSTMASTER in savemail()) to not look at - aliases (ugh). - Some more HPUX tweaking (compile flag hpux => __hpux so it - still works in ANSI mode). - Don't try to flock non-regular files when mailing to a file. - In particular, this was a problem if you tried to - send to /dev/null. - Fix a weird bug that can cause senders to be queued as - recipients if the name server is down when the mail - is initially sent. This hack just ignores sender - deletion (essentially, it sets the MeToo flag) if there - is a TEMPFAIL during processing of the sender address. - Obscure. - Fix a dangling else problem -- from Brian Bullen from University - of Stirling, UK. - Add the "b" mailer flag to force a blank line on the end of - messages. Some brilliant versions of /bin/mail insist - on this but do not add it themselves. - Add the "g" mailer flag to prevent user SMTP from sending - "MAIL From:<>". This is only intended to be a - transitional gesture, and should not be used if at - all possible. It appears that Berkeley and IDA - config files have always handled this properly; the - UK config kit apparently does not. - Don't lowercase and then capitalize header field names -- leave - them with original capitalization. Fixes from Bill - King of Allen-Bradley Company. - Further cleanup and improved reporting of error messages, - particularly conditions that cause messages to be - requeued for future delivery. - Tweak syslog priorities in some cases. - CONFIG: clean up route-addr on UUCP addresses. - -6.55/6.25 93/04/27 - HPUX 8.07 compatibility changes in getla() -- I had to make - these changes to get it to work at Berkeley, although - others seem to have been working before (???). - Various patches to XLA code. - Fix problem that causes setuid bit on files to be ignored from - SMTP or in queue runs. Problem noted by Jason Ornstein - of Under The Wire, Inc. - Fix problem that can cause CNAMEs to be ignored. - Generalize getmxrr to match local host in $=w instead of a - single name passed in. - Some cleanup from Eric Wassenaar: - Use FileMailer instead of ProgMailer in two places. - Eliminate duplicate 8th-bit stripping in commaize. - Fix a problem with mis-parsing of backslash escapes - under some circumstances. - NIS map fix (was always including trailing null character) - from Mike Glendinning of Ingres UK. - Add "a" mailer flag to try using ESMTP. It tries the EHLO - command and if that fails falls back to regular SMTP. - Also parses EHLO option keywords. If host supports - SIZE extension, this is added to the MAIL FROM: - command. - Extend "b" option to include a second value which is the - maximum message size this server is willing to accept. - For example, a value of "10/1000000" says that there - must be ten blocks free, and sendmail will reject - any message larger than one megabyte. - Some portability hooks for NeXT (this could be applicable - to Mach in general). You have to create an empty - file called "unistd.h" to get it to compile. - Adjust config values (MAXLINE, MAXATOM, and PSBUFSIZE) to - be more generous. - Add X400-Received: to the list of headers tagged with H_TRACE - in conf.c. From Bill King, Allen-Bradley Co. - -6.54/6.25 93/04/19 - Fix problem that caused redefinition of SMTP and QUEUE compile - flags. Pointed out by Jon Forrest of the Sequoia 2000 - project at Berkeley. - Properly handle \! hack -- it was treating host\!user as one - token (host!user) instead of three (host, !, user). - Fix from Eric Wassenaar of NIKHEF-H. - Fix compilation problem in getauthinfo() if IDENTPROTO is off. - Turn off DEFNAMES and DNSRCH when getting the hostsignature - (i.e., MX records) in level 1 configuration files; this - matches the old behaviour. From Motonori Nakamura of - Kyoto University. - Improve error message printing -- if sent through an alias, - error messages include the name of the alias in the - message. Unfortunately, in order to make this work - properly in queue runs, this changes the format of the - C line in the qf file. The relatively uselessness of - the previous information was pointed out to me by - Allan E Johannesen of WPI. - Add XLA compile flag to add hooks to Christophe Wolfhugel's - extended load average code. This is still in very early - form. For information regarding the guts of the xla - code, contact Christophe.Wolfhugel@grasp.insa-lyon.fr. - Additional hooks for detecting tempfails in rewriting rules - (that is, in map lookups). - -6.53/6.25 93/04/15 - Properly diagnose ruleset zero returning null (instead of a mailer - triple). From Motonori Nakamura of Kyoto University. - More generalization of socket code for other protocols. - Shorten timeouts on reverse name lookups -- since they are done - during connection establishment, long timeouts here can - cause higher level timeouts. This mainly serves to accept - mail from hosts that do not have proper reverse (PTR) DNS - records set up. - Reset e_statmsg before each mailer invocation to avoid bogus - messages in the log. - Redefine $r, $s, and $_ in error envelopes so you don't get - incorrect cruft in the error message. Problem noted by - Motonori Nakamura of Kyoto University. - Fix a problem that can cause failure to return errors to Postmaster - in certain cases. From Motonori Nakamura. - Fix a problem that can cause some systems to give duplicate error - messages when a bad syntax address such as " $3 - the input "user@a.b.c" failed instead of being properly - rewritten as "user@a..c". - Neil also convinced me that it was correct that $~ should match - only one token -- the problem is that it's always possible - to add another token, so $~ matches far too eagerly. - -6.45/6.21 93/03/25 - Implement multi-word classes (properly!). - -6.44/6.21 93/03/25 - Add X-Authentication-Warning: headers to clue users into possible - attempts to forge mail. This is on the authwarnings - privacy flag, but is the default. Suggested by Bryan - Costales of ICSI. - Pass default units for convtime in so they can be more reasonable. - Allow config files to always add a new Comments: header (i.e., - they will be added even if an old one already exists). - Suggested by Bryan Costales of ICSI. - Allow config files to delete an existing Return-Path: header. - These should only be added at final delivery. Suggested - by Bryan Costales of ICSI. - Some debugging additions. Suggested by Bryan Costales of ICSI. - Clean up logging of Family 0 addresses. Noted by David Muir - Sharnoff and others. - Add a "dequote" map class. This allows config files to strip - quotes off of addresses. Note that this is not a builtin - map, just a class -- so you have to define the map - using the K line. - Fix a bug in the queueup() loop getting a locked tf where in - very odd cases it can fall off the bottom and core dump. - Of course, it was P{r Emanuelsson who found it.... - Open a new transcript when splitting an envelope. Problem found - by Allan E Johannesen of WPI. - Improved error output in endmailer if the mailer core dumps. - CONFIG: Fix typo in UUCP mailer definition. - CONFIG: Default several of the new options on: eight bit input, - privacy flags set to "authwarnings", and message warning - set to 4h. - CONFIG: Use dequote map. - -6.43/6.20 93/03/23 - Fix problem with assumption of an sa_len field in a generic - sockaddr -- it turns out that most vendors haven't - picked up this (very important) fix. - Change compilation flags for daemon code -- select one or both - of NETINET or NETISO, but don't ever set DAEMON manually. - CONFIG: add FEATURE(mailertable) to do IDA-style mailertables. - -6.42/6.19 93/03/19 - Use Postmaster as default fallback return address, not root. - POSIX changes for file descriptor handling. - Diagnose errors writing new queue file. - If you change the owner using an owner- alias, also change the - error mode to EM_MAIL so that errors don't get dropped - into an inappropriate directory. Problem noted by - Allan E Johannesen of WPI. - If you are su'ed to root, send email as who you really are, not - as root. From Brian Kantor of U.C. San Diego. - Allow warning messages to be sent after a configurable interval - has passed without delivery. The message is sent only - once per envelope. This changes the format of the qf - file to have an F line, and the format of the T option - to accept take the format "return/warn" (both intervals). - Don't force all local names to lower case -- this was left over - from the weird handling of case mapping on aliases. It - is now driven (as expected) by the "u" mailer flag. - Problem noted by P{r Emanuelsson. - Fix problem that caused headers on returned email to be trashed; - they were getting freed, but are still accessible via - BlankEnvelope. - Fix problem that caused bogus ids to be created on returned - mail. - Add support for ISO and other non-INET networking. This is by - no means finished yet. This does assume a lot of other - system support, like a version of gethostbyname that - returns non-AF_INET addresses. - CONFIG: change default on prog mailer to keep upper case in - user names (i.e., in the program command line). - CONFIG: strip trailing dots off of hosts in uucp mailer before - convert to bang format. - CONFIG: create new "relay" mailer for $R (LOCAL_RELAY) and $H - (MAIL_HUB) delivery that doesn't add local domain. Note - that this violates 821, but is probably "more correct" - for what we are trying to do. Problem pointed out by - Michael Graff of Iowa State. - -6.41/6.18 93/03/18 - Clean up unnecessary creates of queue ids (i.e., empty qf files) - when not needed, such as when starting up an SMTP - connection. - Fix problem where split envelopes aren't instantiated in the queue. - This is quite a serious bug. - Owner- aliases had problems with leading spaces causing a - premature delimitation. - -6.40/6.18 93/03/18 - Have ending 250 (after DATA) include the id; suggested by - Brian Kantor of UC San Diego. - Add logging on envelope splitting. - Change queue ids to have one more letter encoding the hour of - the day so that during a single day there is a greater - likelihood of uniqueness; requested by Brian Kantor. - -6.39/6.18 93/03/18 - Fix minor compile problem if LOCKF is defined. - Define size of tobuf in conf.h. Observed by Toshinari Takahashi - of Toshiba. - Restore e_sender -- this is equivalent to e_from.q_paddr without - decorations such as angle brackets and comments. - OSF/1 on Alpha changes from Allan E Johannesen of WPI. - CONFIG: fix typo in S3 for list syntax (;: => :;). Thanks to - Christopher Hoover for noting the problem. - -6.38/6.17 93/03/17 - Pass envelope to disconnect to avoid another use of CurEnv, which - can apparently end up being null at inopportune times. - Log "received from" as "relay=" for consistency (suggested by - John Gardiner Myers). - Fix major bug in header handling: if no From: line existed in - the header (so sendmail inserts one), and the sender is - an alias that has an owner, the From: line shows the - owner (as well as the envelope). Fixed by early binding - the headers (which will change debugging output). - HPUX portability patches from Michael J. Corrigan of UC San Diego. - Some attempts to adapt better to out of open file conditions. - Some changes to ctladdr handling in queue files. - -6.37/6.17 93/03/16 - MAJOR CHANGE: delete e_sender and e_returnpath (why are these - different from e_from?) and $< macro. - Log correct IP address in relay= field even if the connection - times out. - Log "received from [RESPONSE]" on EF_RESPONSE messages (from - John Gardiner Myers). - Fixes to SysExMsg logging (sometimes just got "message: %s" - instead of "message: error message"), noted by Eric - Wassenaar. Also reported by Motonori Nakamura. - Improvements to MX piggybacking code, from Motonori Nakamura. - Fix case where CurHostName points to an auto variable that has - been deallocated (from Motonori Nakamura). - Fix bug causing newlines to be included in aliases if option - "n" (check alias RHS) is set; bug noted by David Muir - Sharnoff. - Fix problem causing user names that should be mapped to lower - case to not be mapped if they are sent during a queue - run. This greatly simplifies the case mapping code. - Problem noted by Allan E Johannesen of WPI. - Don't do recipient address rewriting in buildaddr. This - improperly did recipient rewriting on sender addresses, - and just seems bogus in general -- but the change could - break some .cf files. - Pass TZ envariable to child processes for System V. - CONFIG: allow LOCAL_RULE_1 and LOCAL_RULE_2 if you want to - define those rulesets. - KNOWN PROBLEM: I have seen some problems on SunOS that causes - the User Data Base to give errors on some addresses. I - have tracked the problem back at least as far as 93.02.15 - (version 6.22). Running with debugging on makes it - go away, so I conclude that it is referencing uninitialized - stack data. I haven't been able to track this down yet. - -6.36/6.16 93/03/08 - Allow local mailer to specify $@host -- this lets you assign the - "foo" part of jgm+foo to $h for passing in to the local - mailer. - Additional debug printing in getcanonname (show query type). - Don't add the e_fromdomain on sender addresses -- this interacts - weirdly with the owner- code. - Improve delivery logging to not log obvious or meaningless stuff. - Include numeric IP address in Received: lines per RFC 1123 section - 5.2.8. - Fixed a bug in checking stat() return value if restrictmailq is - set. Also, check the entire group set instead of just the - primary group. Both from John Gardiner Myers. - Don't have usrerr automatically print errno, since this is often - misleading. - Use transienterror() in makeconnection after connect() fails and - in openmailer after execve() fails (from Eric Wassenaar). - Also moved transienterror() from util.c to conf.c. - Clean up from= logging on response messages. - Undo patch allowing prescan to return a null vector -- it breaks - too many things. - Config: FEATURE(notsticky) lets you use UDB for everything coming - in to the machine, even if it is specifically targetted - to this machine. Without it, UDB is bypassed if the user - name is fully qualified. - Config: fix another minor botch with <> (local mailer wasn't - mapping them properly). - -6.35/6.15 93/03/05 - Fix getrealhostname to return null if sinlen <= 0 -- this can - occur if stdin is a pipe. - Avoid infinite loop in getcanonname if name server return - NO_DATA (for example). - Config: avoid having C flag qualify list syntax and error syntax. - -6.34/6.14 93/03/05 - Fix logging in deliver to not pass too many parameters to Ultrix - versions of syslog. - Don't write the pid file until after the daemon has actually - opened and conditioned the connection. - Consider addresses "different" if their q_uids differ (so that - two users forwarding to the same program will be seen - as different, rather than the same). - Fix problem with bad parameters in main() -- they set ExitStat - but don't exit. - Fix null pointer references through RealHostName -- painfully - discovered by Allan E Johannesen of WPI. - Fix bug causing user@@localhost to core dump (yuch). - Config: don't put two @host.dom.ain on users in $=E in SMTP - mailer. Also, catch user@ (no host) in ruleset 0. - -6.33/6.13 93/03/03 - Config: add confCW_FILE as the name of the cw configuration file - (defaults to /etc/sendmail.cw). From P{r Emanuelsson. - Allow prescan to return a pointer to an empty list -- this is - not an error. Also, clean up error reporting to avoid - double errors (prescan reports once, then the caller - reports again). - Changes to avoid trusting T_ANY queries -- run them, but if you - don't get the info you expected, do T_A and T_MX queries - anyhow. This also fixes an oversight where _res.options - bits were being ignored. - If PRIV_NOVRFY is set, use 252 response code instead of 502 per - RFC 1123 section 5.2.3. It's not 100% clear that this - is correct, but it probably works better with stupid - mailers that do a VRFY and only check the first digit. - -6.32/6.12 93/03/02 - Fix uninitialized variable "protocol" in smtp code. - Include in sendmail.h -- move towards POSIX/ANSI. - Additional hooks for RFC 1427 (ESMTP SIZE extension). This - includes requiring that enoughspace() know the system - block size, which will undoubtedly break most ports. - Trace flag 19 in use for srvrsmtp.c. - Additional logging -- notably the sending mailer name. This - also changes the delivery logging to strict field=value - syntax. - Fix some problems with messages getting sent even to addresses - that had been marked bad -- from Eric Wassenaar. - More WIDE changes: accept host name inside [...] as non-MXed - host. This is intended ONLY for use inside firewalled - environments, where the MX points at the gateway. - Change .cf file conventions so that mapping for <> addresses - don't have an @ in them (to avoid confusing the C mailer - flag). Pointed out by Neil Rickert. - Config extensions for Sam Leffler's FlexFAX software. - -6.31/6.10 93/02/28 - Fix some more bugs in alias owner code -- there were some weird - cases where an error in a non-aliased name would override - the return info in an aliased name with an owner. - Changes from WIDE Project, forwarded to me by Motonori Nakamura: - Log actual delivery host (after MX et al); from - yasuhiro@dcl.co.jp. - Log daemon startup. - Deliver Postmaster copies without a body. - Better logging of SMTP senders. - Send all program email as daemon even when local. - As requested in various forms from many people, accept -qIstring - to limit queue runs to jobs with queue-id matching string. - Similarly for -qRstring for recipients, -qSstring for - senders. - Initial hooks for ESMTP support (see RFC 1425). - Fixed a syntax error in the UUCP mailer specification that caused - core dumps on startup. - Check for missing A= or P= arguments in mailer definitions. - -6.30/6.10 93/02/27 - Require FROZENCONFIG compilation flag to include frozen - configuration code. Frozen configuration is really - not a very good idea any more, particularly in shared - library environments. - Do better checking of errno after opens of :include: and .forward - files to defer delivery on network and other transient - errors. Suggestion from Craig Everhart. - Fix minor botch in read timeout macro processing. - Add FEATURE(nouucp) to config files for sites that know absolutely - nothing about UUCP. - Add built cf files to distribution tape and clarify how to build - them if you don't have the Berkeley make. - Some sizeof(long) portability changes for the Alpha, from Allan - E Johannesen. - Add "restrictmailq" privacy flag -- if set, only people in the same - group as your queue directory can print the queue. If you - set this, be sure you also restrict access to log files.... - Fix another bug in owner-list stuff that can cause data files to - be "lost". - Fix a bug with queue runs that cause forwards to yourself to go - into alias/forwarding loops. I'm still iffy about this - fix. - Fix from Eric Wassenaar for suppression of return message code. - -6.29/6.9 93/02/24 - Fix yet another problem in alias owner code -- put the wrong return - address on the enclosed return-to-sender letter. - -6.28/6.9 93/02/24 - Fix botch in alias owner code that caused it to not operate if the - error was detected locally. - -6.27/6.9 93/02/24 - M_LOCAL => M_LOCALMAILER to avoid conflict with Ultrix include - file . - Miscellaneous bug fixes from Eric Wassenaar: - sendmail -bv -t logs the from line even though in verify - mode only. - sendmail -v can go into queue mode if shouldqueue returns - TRUE. - Add route-addr pruning per RFC 1123 section 5.3.3. This can be - disabled using the "R" option. - Delete (always undocumented) -R flag (save original recipients); - there are ways to syslog(3) these now. - Clean up SMTP reply codes -- specify them as needed in the code, - instead of in conf.c -- this was needed during the NCP to - TCP transition, but seems silly now. This also changes - parameters to message and nmessage. - Have mailstats read the .cf file to find the sendmail.st file and - get text versions of mailer names. An initial version of - this code was provided by Tuominen Keijo (although the - comments indicate the good bits were written by "E.V."). - Add yet more System V compatibility hacks. - Fix bug in VRFY code (assumes everything must be a local user). - Allow specification of any of the hard-wired pathnames in the - Makefile. - Delete concept of "trusted users" -- this really didn't provide - any security anyway, and caused some problems. - Delete last vestige of support for the word "at" as an equivalent - to the character "@". - Propagate owner-foo alias information into the envelope sender. - Based on code from John Gardiner Myers. This is a major - semantic change -- beware! - Allow $@ on LHS to indicate "match zero" -- this is used to match - the null expression. - -6.26/6.8 93/02/21 - Don't "lose" queue runs. Very important fix from (who else?) - Eric Wassenaar. - Completely reset state on RSET command -- from Eric Wassenaar. - Send error messages and return receipts using an envelope sender - of <> regardless of the setting of $n. Rewriting rules - can undo this if they feel the necessity, as might be - needed for networks that don't understand the syntax. - This is permitted by RFC 821 section 3.6 and required by - RFC 1123 section 5.3.3. THIS REQUIRES VERSION 4 CONFIG - FILES because the rulesets must be able to parse <> - properly. - Don't ever send error messages to "<>" -- they will get sent to - the local postmaster or dumped in /usr/tmp/dead.letter - instead. Per RFC 1123 section 5.3.3. - Explicitly check for email to yourself as a dotted quad. You - have to call $[ [ ... ] $] to get this. - Up the message timeout to five days per RFC 1123 section 5.3.1.1. - Make all read timeouts individually configurable, as strongly - recommended by RFC 1123 section 5.3.2. - Use f_bavail (blocks available to regular users) instead of f_bfree - (blocks available to superuser) in free block checks. - Change $d macro to be the current time, not the origination time, - since this is consistent with how it is used now. - Generalization of enoughspace from Eric Wassenaar covering - SGI, Apollo, HPUX, Ultrix, and SunOS. - Ignore process group signals -- some front ends can do this if - you kill a window too quickly. From Eric Wassenaar. - Change umask to 022. - -6.25/6.8 93/02/20 - Close all cached connections before calling mailers and after - forking for delivery (caused double closes which resulted - in false errors). - Add FEATURE(redirect) in config files -- this allows you to alias - old addresses to a pointer to the new address that will - give a 551 error message, but not deliver the mail. - Some code changes to make the 551 errors look pretty. - Names of M4 program paths in config files have changed -- they - are all XXX_MAILER_PATH now, to match XXX_MAILER_FLAGS. - Fix a bug in the QSELFREF code having to do with empty .forward - files, reported by Eric Wassenaar. - Add option "p" (privacy flags); this allows you to tune how - picky the SMTP server will be. This also adds the - confPRIVACY_FLAGS M4 macro in the config files. - Add option "b" (minimum blocks free). If there are fewer than - this number of blocks free on the filesystem containing - the queue directory, the SMTP MAIL command will return - a 452 response and ask you to try again later. This - also adds the confMIN_FREE_BLOCKS M4 macro in the config - files. - Made VRFY just verify (doesn't expand aliases and .forward files); - EXPN does full expansion. RCPT in queue-only mode also - doesn't chase aliases and .forward. - -6.24/6.7 93/02/19 - Increase the number of domain search entries in domain.c to allow - for the extra "" entry indicating the root domain. - Reported by Motonori Nakamura of Kyoto U. - Add a "SMART_HOST" in the configs for UUCP-connected sites that - want to forward all mail with extra "@"s to that site. - Also allows SMART_HOST, LOCAL_RELAY, and MAIL_HUB to - be specified as ``mailer:hostname'' to use an alternate - mailer. - Clarified and updated some wording in the Operations Guide. - Add the "c" mailer flag -- this suppresses all comment parts of - addresses (requested by John Curran of NEARnet). - Have -v print prompts in -bt mode even if stdin is not a terminal - (default behaviour is to be silent if not reading from - a terminal). Suggested by Bryan Costales, ICSI. - Move the metacharacters from C0 space (\001-\037) into C1 space - (\201-\237). This also fixes a bunch of potential bugs - with G1 characters (\240-\276) in headers relating to - negative numbers passed to isspace() et al. - Add YP_LAST_MODIFIED and YP_MASTER_NAME to DBM version of alias - database if YPCOMPAT is #defined. Enhancement from - Takahiro Kanbe of Fuji Xerox Information Systems Co., Ltd. - Add "list" Precedence (-30); this can be used with old sendmails - which will map to precedence 0 (which will return error - messages). Suggested by Stephen R. van den Berg. - Many bug fixes from Eric Wassenaar of the National Institute for - Nuclear and High-Energy Physics, Amsterdam: - Clear timeouts properly on open failures in include(). - Don't dereference through NULL if no home directory found. - Re-establish SIGCHLD signal on System 5 in reapchild(). - Avoid NULL pointer reference on -pFOO flag. - Properly handle backslash escapes in comments. - Correctly check reply status on SMTP NOOP command. - Properly save SMTP error message if peer gives - "Service Shutting Down" message. - Avoid writing to the transcript if it couldn't be opened. - Signal errors in SMTP children to parent properly. - Handle self references in a list more globally (include a - QSELFREF bit in the address flags). This enhancement - was suggested by Eric Wassenaar. - Use initgroups() in hpux, even though it's System-V based. The - HASINITGROUPS compile flag can set this on other systems. - This HPUX behaviour was pointed out by Eric Wassenaar. - -6.23/6.6 93/02/16 - Clean up handling of LogLevel to make it easier to figure out - what's on what level. - Change log levels to have some consistency: - 1 serious system failures, security problems - 2 lost communications, protocol failures - 3 other serious failures - 4 minor errors - 5 message collection - 6 vrfy logging, creation of return-to-sender - 7 delivery failures - 8 delivery successes - 9 delivery tempfails (queue ups) - 10 database expansion - >64 debugging - Allow IDA-style separated processing on S= and R= in Mailer - definition lines. Note that rulesets 1 and 2 are - still used for both addresses as before. Bruce Lilly - gave a convincing argument that RFC976 insists on - this behaviour. - Added some time zones to arpatounix -- they may not be in the - standards, but they are in use. However, I may delete - arpatounix entirely -- there appears to be no reason - for it to exist. - Change to UUCP mailer (in cf directory) to try to do a saner job. - I'm still not certain about this mailer in general. - -6.22/6.5 93/02/15 - Fix bug that prevents saving letters in ~/dead.letter. - Don't add angle brackets in VRFY command if angle brackets already - exist in the address. - Fix bogus error message in udbexpand. - Null terminate host buffers in buildaddr (broken in 6.21) -- - IMPORTANT FIX!! - -6.21/6.5 93/02/15 - Fix another incorrect error message in alias.c, found by Azuma - Okamoto. - Fix a couple of problems in the more-configurable config files, - found by Tom Ivar Helbekkmo. - Fix problem with quoted :include: entries. - Don't duplicate the filename on verbose printing of .forward and - :include: contents. - Extend size of prescan buffer (to allow bigger addresses). Also, - detect some buffer overflows. - Log user SMTP protocol errors (log level 4). - -6.20/6.4 93/02/14 - Fix another problem in the MCI state machine caused when there - were errors generated from the other end to commands - other than RCPT. - -6.19/6.4 93/02/14 - Include load average support for DEC Alpha running OSF/1. - Fix multiple-response problem with errors in MAIL From: line. - Fix SMTP reply codes for invalid address syntaxes (give 501; - never give multiple error messages for a single message). - Fix problem where a cached connection timeout rejects all - later connects to that host. - Fix incorrect error message if alias.c is compiled with DBM only. - Additional changes to fix nested conditionals (from Bruce Lilly). - Recover more gracefully from operating system failures, particularly - NULL returns from openmailer (from Noritoshi Demizu, - OMRON Corporation). - Log forward, alias, and userdb expand operations on log level 10; - concept suggested by P{r (Pell) Emanuelsson. - Changes for HPUX 8.07 compatibility. - -6.18/6.4 93/02/12 - Allow any config option to be set using an M4 define. - Change UNAME compile flag to HASUNAME for IDA compatibility - (besides, it's a better name). - Note in README that on SunOS it must be linked -Bstatic. - Fairly major change in domain.c to handle wildcard MX records - more rationally. NOTE: the "w" option (no wildcard MX - records match local domain) has been eliminated. - Fix some unset variable references pointed out by Bruce Lilly. - Fix host name in process titles when using cached connection. - -6.17/6.3 93/01/28 - Fix System 5 compatibility changes to be compatible with the rest - of the world. - -6.16/6.3 93/01/28 - Experimental fix for problem handling errors in the SMTP - protocol in conjunction with connection caching. - System 5 compatibility changes. - -6.15/6.3 93/01/26 - Fix a bug that causes local mail delivered using -odq to be - eliminated as a duplicate (because it matched the - ctladdr, now passed in as a C line). These changes - are pretty tricky...... - -6.14/6.3 93/01/25 - Add debugging for some MCI errors. - -6.13/6.3 93/01/22 - Fix -e compatibility flag to take a value. - Fix a couple of minor compilation warnings on Sun cc. - Improve error messages in a few cases to be more self-explanatory. - -6.12/6.3 93/01/21 - Fix yet-another problem with environment handling, pointed out - by Yoshitaka Tokugawa and Tom Ivar Helbekkmo. - Some heuristics to try to limit resource exhaustion problems - if a downstream host has been down for a long time. - Fix problem with incorrect host name being logged in "Connection - timed out" messages (from Tom Ivar Helbekkmo). - Fix some ANSI C problems (from Takahiro Kanbe). - Properly log message sender on returned mail during queue run. - Count number of recipients properly. - Fix a problem in yp map code. - Diagnose "message timed out" (from Motonori Nakamura). - -6.11/6.3 93/01/20 - Fix problem with address delimitor inside quotes. - Define $k and $=k to be the UUCP name (from the uname call) - based on code from Bruce Lilly. - -6.10/6.2 93/01/18 - Implement arpatounix (largely code from Bruce Lilly). - Log more info (suggested by John Myers). - Allow nested $?...$|...$. (inspired by code from Bruce Lilly of - Sony US). - POSIX compatibility (noted by Keith Bostic). - Handle SMTP MAIL command errors properly (urged by several people, - notably John Myers of CMU). - Do early diagnosis of .cf errors (notably referencing a RHS - substitution that isn't on the LHS). - Adjust checkpointing to better handle batched recipients, suggested - by John Myers. - Fix miscellaneous bugs. - (config files:) Implement MAIL_HUB for all local mail (to handle - NFS-mounted directories) as urged by Tom Ivar Helbekkmo - of the Norwegian School of Economics. - -6.9/6.1 93/01/13 - Environment handling simplification/bug fix -- child processes - get a minimal, fixed environment. This avoids different - behaviour in queue runs. - Handle commas inside comments properly. - Properly limit large messages submitted in -obq mode. - -6.8/6.1 93/01/10 - Check mtime of thaw file against .cf and sendmail binary, based on - code from John Myers. - -6.7/6.1 93/01/10 - MX piggybacking, based on code from John Myers@CMU. - Allow checkcompat to return -1 to mean tempfail. - Bug fix in m_mno computation. - -6.6/6.1 93/01/09 - Tuning of queueing functions as recommended by John Gardiner Myers. - Return mail headers (no body) on messages with negative precedence. - Minor other bug fixes. - -6.5/6.1 93/01/03 - Fix botch causing queued headers to have ?XX? prefixes. - -6.4/6.1 93/01/02 - Changes to recognize special mailer types (e.g., file) early. - -6.3/6.1 93/01/01 - Pass timeouts to sfgets. - Check for control characters in addresses. - Fixed deferred error reporting. - Report duplicate aliases. - Handle mixed case recursive aliases. - Misc bug fixes. - -6.2/6.1 92/12/30 - Put return-receipt-to on a conf.c flag (but don't set it). - Fix minor syslog problem. diff --git a/usr.sbin/sendmail/cf/README b/usr.sbin/sendmail/cf/README deleted file mode 100644 index 184a3532559e..000000000000 --- a/usr.sbin/sendmail/cf/README +++ /dev/null @@ -1,1857 +0,0 @@ - - - NEW SENDMAIL CONFIGURATION FILES - - Eric Allman - - @(#)README 8.124 (Berkeley) 9/23/97 - - -This document describes the sendmail configuration files being used -at Berkeley.

The -local mailer is always included automatically. Beware: MAILER -declarations should always be at the end of the configuration file, -and MAILER(smtp) should always precede MAILER(uucp). The general -rules are that the order should be: - - VERSIONID - OSTYPE - DOMAIN - FEATURE - local macro definitions - MAILER - LOCAL_RULESET_* - - -+----------------------------+ -| A BRIEF INTRODUCTION TO M4 | -+----------------------------+ - -Sendmail uses the M4 macro processor to ``compile'' the configuration -files. The most important thing to know is that M4 is stream-based, -that is, it doesn't understand about lines. For this reason, in some -places you may see the word ``dnl'', which standards for ``delete -through newline''; essentially, it deletes all characters starting -at the ``dnl'' up to and including the next newline character. In -most cases sendmail uses this only to avoid lots of unnecessary -blank lines in the output. - -Other important directives are define(A, B) which defines the macro -``A'' to have value ``B''. Macros are expanded as they are read, so -one normally quotes both values to prevent expansion. For example, - - define(`SMART_HOST', `smart.foo.com') - -One word of warning: M4 macros are expanded even in lines that appear -to be comments. For example, if you have - - # See FEATURE(foo) above - -it will not do what you expect, because the FEATURE(foo) will be -expanded. This also applies to - - # And then define the $X macro to be the return address - -because ``define'' is an M4 keyword. If you want to use them, surround -them with directed quotes, `like this'. - - -+--------+ -| OSTYPE | -+--------+ - -You MUST define an operating system environment, or the configuration -file build will puke. There are several environments available; look -at the "ostype" directory for the current list. This macro changes -things like the location of the alias file and queue directory. Some -of these files are identical to one another. - -It is IMPERATIVE that the OSTYPE occur before any MAILER definitions. -In general, the OSTYPE macro should go immediately after any version -information, and MAILER definitions should always go last. - -Operating system definitions are usually easy to write. They may define -the following variables (everything defaults, so an ostype file may be -empty). Unfortunately, the list of configuration-supported systems is -not as broad as the list of source-supported systems, since many of -the source contributors do not include corresponding ostype files. - -ALIAS_FILE [/etc/aliases] The location of the text version - of the alias file(s). It can be a comma-separated - list of names (but be sure you quote values with - commas in them -- for example, use - define(`ALIAS_FILE', `a,b') - to get "a" and "b" both listed as alias files; - otherwise the define() primitive only sees "a"). -HELP_FILE [/usr/lib/sendmail.hf] The name of the file - containing information printed in response to - the SMTP HELP command. -QUEUE_DIR [/var/spool/mqueue] The directory containing - queue files. -STATUS_FILE [/etc/sendmail.st] The file containing status - information. -LOCAL_MAILER_PATH [/bin/mail] The program used to deliver local mail. -LOCAL_MAILER_FLAGS [rmn] The flags used by the local mailer.

The - flags lsDFM are always included. -LOCAL_SHELL_ARGS [sh -c $u] The arguments passed to deliver "prog" - mail. -LOCAL_SHELL_DIR [$z:/] The directory search path in which the - shell should run. -USENET_MAILER_PATH [/usr/lib/news/inews] The name of the program - used to submit news. -USENET_MAILER_FLAGS [rlsDFMmn] The mailer flags for the usenet mailer. -USENET_MAILER_ARGS [-m -h -n] The command line arguments for the - usenet mailer. -USENET_MAILER_MAX [100000] The maximum size of messages that will - be accepted by the usenet mailer. -SMTP_MAILER_FLAGS [undefined] Flags added to SMTP mailer. Default - flags are `mDFMUX' for all SMTP-based mailers; the - "esmtp" mailer adds `a' and "smtp8" adds `8'. -SMTP_MAILER_MAX [undefined] The maximum size of messages that will - be transported using the smtp, smtp8, or esmtp - mailers. -SMTP_MAILER_ARGS [IPC $h] The arguments passed to the smtp mailer. - About the only reason you would want to change this - would be to change the default port. -ESMTP_MAILER_ARGS [IPC $h] The arguments passed to the esmtp mailer. -SMTP8_MAILER_ARGS [IPC $h] The arguments passed to the smtp8 mailer. -RELAY_MAILER_ARGS [IPC $h] The arguments passed to the relay mailer. -SMTP_MAILER_CHARSET [undefined] If defined, messages containing 8-bit data - that ARRIVE from an address that resolves to one of - the SMTP mailers and which are converted to MIME will - be labelled with this character set. -UUCP_MAILER_PATH [/usr/bin/uux] The program used to send UUCP mail. -UUCP_MAILER_FLAGS [undefined] Flags added to UUCP mailer. Default - flags are `DFMhuU' (and `m' for uucp-new mailer, - minus `U' for uucp-dom mailer). -UUCP_MAILER_ARGS [uux - -r -z -a$g -gC $h!rmail ($u)] The arguments - passed to the UUCP mailer. -UUCP_MAILER_MAX [100000] The maximum size message accepted for - transmission by the UUCP mailers. -UUCP_MAILER_CHARSET [undefined] If defined, messages containing 8-bit data - that ARRIVE from an address that resolves to one of - the UUCP mailers and which are converted to MIME will - be labelled with this character set. -FAX_MAILER_PATH [/usr/local/lib/fax/mailfax] The program used to - submit FAX messages. -FAX_MAILER_ARGS [mailfax $u $h $f] The arguments passed to the FAX - mailer. -FAX_MAILER_MAX [100000] The maximum size message accepted for - transmission by FAX. -POP_MAILER_PATH [/usr/lib/mh/spop] The pathname of the POP mailer. -POP_MAILER_FLAGS [Penu] Flags added to POP mailer. Flags "lsDFM" - are always added. -POP_MAILER_ARGS [pop $u] The arguments passed to the POP mailer. -PROCMAIL_MAILER_PATH [/usr/local/bin/procmail] The path to the procmail - program. This is also used by FEATURE(local_procmail). -PROCMAIL_MAILER_FLAGS [SPhnu9] Flags added to Procmail mailer. Flags - ``DFM'' are always set. This is NOT used by - FEATURE(local_procmail); tweak LOCAL_MAILER_FLAGS - instead. -PROCMAIL_MAILER_ARGS [procmail -Y -m $h $f $u] The arguments passed to - the Procmail mailer. This is NOT used by - FEATURE(local_procmail); tweak LOCAL_MAILER_ARGS - instead. -PROCMAIL_MAILER_MAX [undefined] If set, the maximum size message that - will be accepted by the procmail mailer. -MAIL11_MAILER_PATH [/usr/etc/mail11] The path to the mail11 mailer. -MAIL11_MAILER_FLAGS [nsFx] Flags for the mail11 mailer. -MAIL11_MAILER_ARGS [mail11 $g $x $h $u] Arguments passed to the mail11 - mailer. -PH_MAILER_PATH [/usr/local/etc/phquery] The path to the phquery - program. -PH_MAILER_FLAGS [ehmu] Flags for the phquery mailer. -PH_MAILER_ARGS [phquery -- $u] -- arguments to the phquery mailer. -CYRUS_MAILER_FLAGS [A5@] The flags used by the cyrus mailer. The - flags lsDFMnP are always included. -CYRUS_MAILER_PATH [/usr/cyrus/bin/deliver] The progam used to deliver - cyrus mail. -CYRUS_MAILER_ARGS [deliver -e -m $h -- $u] The arguments passed - to deliver cyrus mail. -CYRUS_MAILER_MAX [undefined] If set, the maximum size message that - will be accepted by the cyrus mailer. -CYRUS_MAILER_USER [cyrus:mail] The user and group to become when - running the cyrus mailer. -CYRUS_BB_MAILER_FLAGS [undefined] The flags used by the cyrusbb - mailer. The flags lsDFMnP are always included. -CYRUS_BB_MAILER_ARGS [deliver -e -m $u] The arguments passed - to deliver cyrusbb mail. - - - -+---------+ -| DOMAINS | -+---------+ - -You will probably want to collect domain-dependent defines into one -file, referenced by the DOMAIN macro. For example, our Berkeley -domain file includes definitions for several internal distinguished -hosts: - -UUCP_RELAY The host that will accept UUCP-addressed email. - If not defined, all UUCP sites must be directly - connected. -BITNET_RELAY The host that will accept BITNET-addressed email. - If not defined, the .BITNET pseudo-domain won't work. -DECNET_RELAY The host that will accept DECNET-addressed email. - If not defined, the .DECNET pseudo-domain and addresses - of the form node::user will not work. -FAX_RELAY The host that will accept mail to the .FAX pseudo-domain. - The "fax" mailer overrides this value. -LOCAL_RELAY DEPRECATED. The site that will handle unqualified - names -- that is, names with out an @domain extension. - If not set, they are assumed to belong on this machine. - This allows you to have a central site to store a - company- or department-wide alias database. This - only works at small sites, and only with some user - agents. -LUSER_RELAY The site that will handle lusers -- that is, apparently - local names that aren't local accounts or aliases. - -Any of these can be either ``mailer:hostname'' (in which case the -mailer is the internal mailer name, such as ``uucp-new'' and the hostname -is the name of the host as appropriate for that mailer) or just a -``hostname'', in which case a default mailer type (usually ``relay'', -a variant on SMTP) is used. WARNING: if you have a wildcard MX -record matching your domain, you probably want to define these to -have a trailing dot so that you won't get the mail diverted back -to yourself. - -The domain file can also be used to define a domain name, if needed -(using "DD") and set certain site-wide features. If all hosts -at your site masquerade behind one email name, you could also use -MASQUERADE_AS here. - -You do not have to define a domain -- in particular, if you are a -single machine sitting off somewhere, it is probably more work than -it's worth. This is just a mechanism for combining "domain dependent -knowledge" into one place. - -+---------+ -| MAILERS | -+---------+ - -There are fewer mailers supported in this version than the previous -version, owing mostly to a simpler world. As a general rule, put the -MAILER definitions last in your .mc file, and always put MAILER(smtp) -before MAILER(uucp) -- several features and definitions will modify -the definition of mailers, and the smtp mailer modifies the UUCP -mailer. - -local The local and prog mailers. You will almost always - need these; the only exception is if you relay ALL - your mail to another site. This mailer is included - automatically. - -smtp The Simple Mail Transport Protocol mailer. This does - not hide hosts behind a gateway or another other - such hack; it assumes a world where everyone is - running the name server. This file actually defines - four mailers: "smtp" for regular (old-style) SMTP to - other servers, "esmtp" for extended SMTP to other - servers, "smtp8" to do SMTP to other servers without - converting 8-bit data to MIME (essentially, this is - your statement that you know the other end is 8-bit - clean even if it doesn't say so), and "relay" for - transmission to our RELAY_HOST, LUSER_RELAY, or - MAILER_HUB. - -uucp The Unix-to-Unix Copy Program mailer. Actually, this - defines two mailers, "uucp-old" (a.k.a. "uucp") and - "uucp-new" (a.k.a. "suucp"). The latter is for when you - know that the UUCP mailer at the other end can handle - multiple recipients in one transfer. If the smtp mailer - is also included in your configuration, two other mailers - ("uucp-dom" and "uucp-uudom") are also defined [warning: - you MUST specify MAILER(smtp) before MAILER(uucp)]. When you - include the uucp mailer, sendmail looks for all names in - the $=U class and sends them to the uucp-old mailer; all - names in the $=Y class are sent to uucp-new; and all - names in the $=Z class are sent to uucp-uudom. Note that - this is a function of what version of rmail runs on - the receiving end, and hence may be out of your control. - See the section below describing UUCP mailers in more - detail. - -usenet Usenet (network news) delivery. If this is specified, - an extra rule is added to ruleset 0 that forwards all - local email for users named ``group.usenet'' to the - ``inews'' program. Note that this works for all groups, - and may be considered a security problem. - -fax Facsimile transmission. This is experimental and based - on Sam Leffler's HylaFAX software. For more information, - see http://www.vix.com/hylafax/. - -pop Post Office Protocol. - -procmail An interface to procmail (does not come with sendmail). - This is designed to be used in mailertables. For example, - a common question is "how do I forward all mail for a given - domain to a single person?". If you have this mailer - defined, you could set up a mailertable reading: - - host.com procmail:/etc/procmailrcs/host.com - - with the file /etc/procmailrcs/host.com reading: - - :0 # forward mail for host.com - ! -oi -f $1 person@other.host - - This would arrange for (anything)@host.com to be sent - to person@other.host. Within the procmail script, $1 is - the name of the sender and $2 is the name of the recipient. - If you use this with FEATURE(local_procmail), the FEATURE - should be listed first. - -mail11 The DECnet mail11 mailer, useful only if you have the mail11 - program from gatekeeper.dec.com:/pub/DEC/gwtools (and - DECnet, of course). This is for Phase IV DECnet support; - if you have Phase V at your site you may have additional - problems. - -phquery The phquery program. This is somewhat counterintuitively - referenced as the "ph" mailer internally. It can be used - to do CCSO name server lookups. The phquery program, which - this mailer uses, is distributed with the ph client. - -cyrus The cyrus and cyrusbb mailers. The cyrus mailer delivers to - a local cyrus user. this mailer can make use of the - "user+detail@local.host" syntax; it will deliver the mail to - the user's "detail" mailbox if the mailbox's ACL permits. - The cyrusbb mailer delivers to a system-wide cyrus mailbox - if the mailbox's ACL permits. - - -The local mailer accepts addresses of the form "user+detail", where -the "+detail" is not used for mailbox matching but is available -to certain local mail programs (in particular, see FEATURE(local_procmail)). -For example, "eric", "eric+sendmail", and "eric+sww" all indicate -the same user, but additional arguments , "sendmail", and "sww" -may be provided for use in sorting mail. - - -+----------+ -| FEATURES | -+----------+ - -Special features can be requested using the "FEATURE" macro. For -example, the .mc line: - - FEATURE(use_cw_file) - -tells sendmail that you want to have it read an /etc/sendmail.cw -file to get values for class $=w. The FEATURE may contain a single -optional parameter -- for example: - - FEATURE(mailertable, dbm /usr/lib/mailertable) - -Available features are: - -use_cw_file Read the file /etc/sendmail.cw file to get alternate - names for this host. This might be used if you were - on a host that MXed for a dynamic set of other - hosts. If the set is static, just including the line - "Cw ..." is probably superior. - The actual filename can be overridden by redefining - confCW_FILE. - -use_ct_file Read the file /etc/sendmail.ct file to get the names - of users that will be ``trusted'', that is, able to - set their envelope from address using -f without - generating a warning message. - The actual filename can be overridden by redefining - confCT_FILE. - -redirect Reject all mail addressed to "address.REDIRECT" with - a ``551 User not local; please try
'' message. - If this is set, you can alias people who have left - to their new address with ".REDIRECT" appended. - -nouucp Don't do anything special with UUCP addresses at all. - -nocanonify Don't pass addresses to $[ ... $] for canonification. - This would generally only be used by sites that only - act as mail gateways or which have user agents that do - full canonification themselves. You may also want to - use "define(`confBIND_OPTS',`-DNSRCH -DEFNAMES')" to - turn off the usual resolver options that do a similar - thing. - -stickyhost If set, email sent to "user@local.host" are marked - as "sticky" -- that is, the local addresses aren't - matched against UDB and don't go through ruleset 5. - This is used if you want a set up where "user" is - not necessarily the same as "user@local.host", e.g., - to make a distinct domain-wide namespace. Prior to - 8.7 this was the default, and notsticky was used to - turn this off. - -mailertable Include a "mailer table" which can be used to override - routing for particular domains. The argument of the - FEATURE may be the key definition. If none is specified, - the definition used is: - hash -o /etc/mailertable - Keys in this database are fully qualified domain names - or partial domains preceded by a dot -- for example, - "vangogh.CS.Berkeley.EDU" or ".CS.Berkeley.EDU". - Values must be of the form: - mailer:domain - where "mailer" is the internal mailer name, and "domain" - is where to send the message. These maps are not - reflected into the message header. - -domaintable Include a "domain table" which can be used to provide - domain name mapping. Use of this should really be - limited to your own domains. It may be useful if you - change names (e.g., your company changes names from - oldname.com to newname.com). The argument of the - FEATURE may be the key definition. If none is specified, - the definition used is: - hash -o /etc/domaintable - The key in this table is the domain name; the value is - the new (fully qualified) domain. Anything in the - domaintable is reflected into headers; that is, this - is done in ruleset 3. - -bitdomain Look up bitnet hosts in a table to try to turn them into - internet addresses. The table can be built using the - bitdomain program contributed by John Gardiner Myers. - The argument of the FEATURE may be the key definition; if - none is specified, the definition used is: - hash -o /etc/bitdomain.db - Keys are the bitnet hostname; values are the corresponding - internet hostname. - -uucpdomain Similar feature for UUCP hosts. The default map definition - is: - hash -o /etc/uudomain.db - At the moment there is no automagic tool to build this - database. - -always_add_domain - Include the local host domain even on locally delivered - mail. Normally it is not added on unqualified names. - However, if you use a shared message store but do not use - the same user name space everywhere, you may need the host - name on local names. - -allmasquerade If masquerading is enabled (using MASQUERADE_AS), this - feature will cause recipient addresses to also masquerade - as being from the masquerade host. Normally they get - the local hostname. Although this may be right for - ordinary users, it can break local aliases. For example, - if you send to "localalias", the originating sendmail will - find that alias and send to all members, but send the - message with "To: localalias@masqueradehost". Since that - alias likely does not exist, replies will fail. Use this - feature ONLY if you can guarantee that the ENTIRE - namespace on your masquerade host supersets all the - local entries. - -limited_masquerade - Normally, any hosts listed in $=w are masqueraded. If this - feature is given, only the hosts listed in $=M are masqueraded. - This is useful if you have several domains with disjoint - namespaces hosted on the same machine. - -masquerade_entire_domain - If masquerading is enabled (using MASQUERADE_AS) and - MASQUERADE_DOMAIN (see below) is set, this feature will - cause addresses to be rewritten such that the masquerading - domains are actually entire domains to be hidden. All - hosts within the masquerading domains will be rewritten - to the masquerade name (used in MASQUERADE_AS). For example, - if you have: - - MASQUERADE_AS(masq.com) - MASQUERADE_DOMAIN(foo.org) - MASQUERADE_DOMAIN(bar.com) - - then *foo.org and *bar.com are converted to masq.com. Without - this feature, only foo.org and bar.com are masqueraded. - - NOTE: only domains within your jurisdiction and - current hierarchy should be masqueraded using this. - -genericstable This feature will cause certain addresses originating in the - local domain or a domain listed in $=G to be looked up in a - map and turned into another ("generic") form, which can change - both the domain name and the user name. This is similar to - the userdb functionality. The same types of addresses as for - masquerading are looked up, i.e. only header sender addresses - unless the allmasquerade and/or masquerade_envelope features - are given. The addresses must be in the list of names given - by the macros GENERICS_DOMAIN or GENERICS_DOMAIN_FILE - (analogously to MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE, - see below). - - The argument of FEATURE(genericstable) may be the map - defintion; the default map definition is: - - hash -o /etc/genericstable - - The key for this table is either the full address or the - unqualified username (the former is tried first); the - value is the new user address. If the new user address does - not include a domain, $j is used. Note that the address - being looked up must be fully qualified. For local mail, it - is necessary to use FEATURE(always_add_domain) for the - addresses to be qualified. - -virtusertable A domain-specific form of aliasing, allowing multiple - virtual domains to be hosted on one machine. For example, - if the virtuser table contained: - - info@foo.com foo-info - info@bar.com bar-info - @baz.org jane@elsewhere.net - - then mail addressed to info@foo.com will be sent to the - address foo-info, mail addressed to info@bar.com will be - delivered to bar-info, and mail addressed to anyone at - baz.org will be sent to jane@elsewhere.net. The username - from the original address is passed as %1 allowing: - - @foo.org %1@elsewhere.com - - meaning someone@foo.org will be sent to someone@elsewhere.com. - - All the host names on the left hand side (foo.com, bar.com, - and baz.org) must be in $=w. The default map definition is: - - hash -o /etc/virtusertable - - A new definition can be specified as the second argument of - the FEATURE macro, such as - - FEATURE(virtusertable, dbm -o /etc/mail/virtusers) - -nodns We aren't running DNS at our site (for example, - we are UUCP-only connected). It's hard to consider - this a "feature", but hey, it had to go somewhere. - Actually, as of 8.7 this is a no-op -- remove "dns" from - the hosts service switch entry instead. - -nullclient This is a special case -- it creates a stripped down - configuration file containing nothing but support for - forwarding all mail to a central hub via a local - SMTP-based network. The argument is the name of that - hub. - - The only other feature that should be used in conjunction - with this one is "nocanonify" (this causes addresses to - be sent unqualified via the SMTP connection; normally - they are qualifed with the masquerade name, which - defaults to the name of the hub machine). No mailers - should be defined. No aliasing or forwarding is done. - -local_procmail Use procmail as the local mailer. This mailer can - make use of the "user+indicator@local.host" syntax; - normally the +indicator is just tossed, but by default - it is passed as the -a argument to procmail. The - argument to this feature is the pathname of procmail, - which defaults to PROCMAIL_MAILER_PATH. Note that this - does NOT use PROCMAIL_MAILER_FLAGS or PROCMAIL_MAILER_ARGS - for the local mailer; tweak LOCAL_MAILER_FLAGS and - LOCAL_MAILER_ARGS instead. - -bestmx_is_local Accept mail as though locally addressed for any host that - lists us as the best possible MX record. This generates - additional DNS traffic, but should be OK for low to - medium traffic hosts. THIS FEATURE IS FUNDAMENTALLY - INCOMPATIBLE WITH WILDCARD MX RECORDS!!! If you have - a wildcard MX record that matches your domain, you - cannot use this feature. - -smrsh Use the SendMail Restricted SHell (smrsh) provided - with the distribution instead of /bin/sh for mailing - to programs. This improves the ability of the local - system administrator to control what gets run via - e-mail. If an argument is provided it is used as the - pathname to smrsh; otherwise, /usr/local/etc/smrsh is - assumed. - - -+-------+ -| HACKS | -+-------+ - -Some things just can't be called features. To make this clear, -they go in the hack subdirectory and are referenced using the HACK -macro. These will tend to be site-dependent. The release -includes the Berkeley-dependent "cssubdomain" hack (that makes -sendmail accept local names in either Berkeley.EDU or CS.Berkeley.EDU; -this is intended as a short-term aid while we move hosts into -subdomains. - - -+--------------------+ -| SITE CONFIGURATION | -+--------------------+ - - ***************************************************** - * This section is really obsolete, and is preserved * - * only for back compatibility. You should plan on * - * using mailertables for new installations. In * - * particular, it doesn't work for the newer forms * - * of UUCP mailers, such as uucp-uudom. * - ***************************************************** - -Complex sites will need more local configuration information, such as -lists of UUCP hosts they speak with directly. This can get a bit more -tricky. For an example of a "complex" site, see cf/ucbvax.mc. - -If your host is known by several different names, you need to augment -the $=w class. This is a list of names by which you are known, and -anything sent to an address using a host name in this list will be -treated as local mail. You can do this in two ways: either create -the file /etc/sendmail.cw containing a list of your aliases (one per -line), and use ``FEATURE(use_cw_file)'' in the .mc file, or add the -line: - - Cw alias.host.name - -at the end of that file. See the ``vangogh.mc'' file for an example. -Be sure you use the fully-qualified name of the host, rather than a -short name. - -The SITECONFIG macro allows you to indirectly reference site-dependent -configuration information stored in the siteconfig subdirectory. For -example, the line - - SITECONFIG(uucp.ucbvax, ucbvax, U) - -reads the file uucp.ucbvax for local connection information. The -second parameter is the local name (in this case just "ucbvax" since -it is locally connected, and hence a UUCP hostname). The third -parameter is the name of both a macro to store the local name (in -this case, $U) and the name of the class (e.g., $=U) in which to store -the host information read from the file. Another SITECONFIG line reads - - SITECONFIG(uucp.ucbarpa, ucbarpa.Berkeley.EDU, W) - -This says that the file uucp.ucbarpa contains the list of UUCP sites -connected to ucbarpa.Berkeley.EDU. The $=W class will be used to -store this list, and $W is defined to be ucbarpa.Berkeley.EDU, that -is, the name of the relay to which the hosts listed in uucp.ucbarpa -are connected. [The machine ucbarpa is gone now, but I've left -this out-of-date configuration file around to demonstrate how you -might do this.] - -Note that the case of SITECONFIG with a third parameter of ``U'' is -special; the second parameter is assumed to be the UUCP name of the -local site, rather than the name of a remote site, and the UUCP name -is entered into $=w (the list of local hostnames) as $U.UUCP. - -The siteconfig file (e.g., siteconfig/uucp.ucbvax.m4) contains nothing -more than a sequence of SITE macros describing connectivity. For -example: - - SITE(cnmat) - SITE(sgi olympus) - -The second example demonstrates that you can use two names on the -same line; these are usually aliases for the same host (or are at -least in the same company). - - -+--------------------+ -| USING UUCP MAILERS | -+--------------------+ - -It's hard to get UUCP mailers right because of the extremely ad hoc -nature of UUCP addressing. These config files are really designed -for domain-based addressing, even for UUCP sites. - -There are four UUCP mailers available. The choice of which one to -use is partly a matter of local preferences and what is running at -the other end of your UUCP connection. Unlike good protocols that -define what will go over the wire, UUCP uses the policy that you -should do what is right for the other end; if they change, you have -to change. This makes it hard to do the right thing, and discourages -people from updating their software. In general, if you can avoid -UUCP, please do. - -The major choice is whether to go for a domainized scheme or a -non-domainized scheme. This depends entirely on what the other -end will recognize. If at all possible, you should encourage the -other end to go to a domain-based system -- non-domainized addresses -don't work entirely properly. - -The four mailers are: - - uucp-old (obsolete name: "uucp") - This is the oldest, the worst (but the closest to UUCP) way of - sending messages accros UUCP connections. It does bangify - everything and prepends $U (your UUCP name) to the sender's - address (which can already be a bang path itself). It can - only send to one address at a time, so it spends a lot of - time copying duplicates of messages. Avoid this if at all - possible. - - uucp-new (obsolete name: "suucp") - The same as above, except that it assumes that in one rmail - command you can specify several recipients. It still has a - lot of other problems. - - uucp-dom - This UUCP mailer keeps everything as domain addresses. - Basically, it uses the SMTP mailer rewriting rules. This mailer - is only included if MAILER(smtp) is also specified. - - Unfortunately, a lot of UUCP mailer transport agents require - bangified addresses in the envelope, although you can use - domain-based addresses in the message header. (The envelope - shows up as the From_ line on UNIX mail.) So.... - - uucp-uudom - This is a cross between uucp-new (for the envelope addresses) - and uucp-dom (for the header addresses). It bangifies the - envelope sender (From_ line in messages) without adding the - local hostname, unless there is no host name on the address - at all (e.g., "wolf") or the host component is a UUCP host name - instead of a domain name ("somehost!wolf" instead of - "some.dom.ain!wolf"). This is also included only if MAILER(smtp) - is also specified. - -Examples: - -We are on host grasp.insa-lyon.fr (UUCP host name "grasp"). The -following summarizes the sender rewriting for various mailers. - -Mailer sender rewriting in the envelope ------- ------ ------------------------- -uucp-{old,new} wolf grasp!wolf -uucp-dom wolf wolf@grasp.insa-lyon.fr -uucp-uudom wolf grasp.insa-lyon.fr!wolf - -uucp-{old,new} wolf@fr.net grasp!fr.net!wolf -uucp-dom wolf@fr.net wolf@fr.net -uucp-uudom wolf@fr.net fr.net!wolf - -uucp-{old,new} somehost!wolf grasp!somehost!wolf -uucp-dom somehost!wolf somehost!wolf@grasp.insa-lyon.fr -uucp-uudom somehost!wolf grasp.insa-lyon.fr!somehost!wolf - -If you are using one of the domainized UUCP mailers, you really want -to convert all UUCP addresses to domain format -- otherwise, it will -do it for you (and probably not the way you expected). For example, -if you have the address foo!bar!baz (and you are not sending to foo), -the heuristics will add the @uucp.relay.name or @local.host.name to -this address. However, if you map foo to foo.host.name first, it -will not add the local hostname. You can do this using the uucpdomain -feature. - - -+-------------------+ -| TWEAKING RULESETS | -+-------------------+ - -For more complex configurations, you can define special rules. -The macro LOCAL_RULE_3 introduces rules that are used in canonicalizing -the names. Any modifications made here are reflected in the header. - -A common use is to convert old UUCP addreses to SMTP addresses using -the UUCPSMTP macro. For example: - - LOCAL_RULE_3 - UUCPSMTP(decvax, decvax.dec.com) - UUCPSMTP(research, research.att.com) - -will cause addresses of the form "decvax!user" and "research!user" -to be converted to "user@decvax.dec.com" and "user@research.att.com" -respectively. - -This could also be used to look up hosts in a database map: - - LOCAL_RULE_3 - R$* < @ $+ > $* $: $1 < @ $(hostmap $2 $) > $3 - -This map would be defined in the LOCAL_CONFIG portion, as shown below. - -Similarly, LOCAL_RULE_0 can be used to introduce new parsing rules. -For example, new rules are needed to parse hostnames that you accept -via MX records. For example, you might have: - - LOCAL_RULE_0 - R$+ <@ host.dom.ain.> $#uucp $@ cnmat $: $1 < @ host.dom.ain.> - -You would use this if you had installed an MX record for cnmat.Berkeley.EDU -pointing at this host; this rule catches the message and forwards it on -using UUCP. - -You can also tweak rulesets 1 and 2 using LOCAL_RULE_1 and LOCAL_RULE_2. -These rulesets are normally empty. - -A similar macro is LOCAL_CONFIG. This introduces lines added after the -boilerplate option setting but before rulesets, and can be used to -declare local database maps or whatever. For example: - - LOCAL_CONFIG - Khostmap hash /etc/hostmap.db - Kyplocal nis -m hosts.byname - - -+---------------------------+ -| MASQUERADING AND RELAYING | -+---------------------------+ - -You can have your host masquerade as another using - - MASQUERADE_AS(host.domain) - -This causes mail being sent to be labeled as coming from the -indicated host.domain, rather than $j. One normally masquerades as -one of one's own subdomains (for example, it's unlikely that I would -choose to masquerade as an MIT site). This behaviour is modified by -a plethora of FEATUREs; in particular, see masquerade_envelope, -allmasquerade, limited_masquerade, and masquerade_entire_domain. - -The masquerade name is not normally canonified, so it is important -that it be your One True Name, that is, fully qualified and not a -CNAME. However, if you use a CNAME, the receiving side may canonify -it for you, so don't think you can cheat CNAME mapping this way. - -Normally the only addresses that are masqueraded are those that come -from this host (that is, are either unqualified or in $=w, the list -of local domain names). You can augment this list using - - MASQUERADE_DOMAIN(otherhost.domain) - -The effect of this is that although mail to user@otherhost.domain -will not be delivered locally, any mail including any user@otherhost.domain -will, when relayed, be rewritten to have the MASQUERADE_AS address. -This can be a space-separated list of names. - -If these names are in a file, you can use - - MASQUERADE_DOMAIN_FILE(filename) - -to read the list of names from the indicated file. - -Normally only header addresses are masqueraded. If you want to -masquerade the envelope as well, use - - FEATURE(masquerade_envelope) - -There are always users that need to be "exposed" -- that is, their -internal site name should be displayed instead of the masquerade name. -Root is an example. You can add users to this list using - - EXPOSED_USER(usernames) - -This adds users to class E; you could also use something like - - FE/etc/sendmail.cE - -You can also arrange to relay all unqualified names (that is, names -without @host) to a relay host. For example, if you have a central -email server, you might relay to that host so that users don't have -to have .forward files or aliases. You can do this using - - define(`LOCAL_RELAY', mailer:hostname) - -The ``mailer:'' can be omitted, in which case the mailer defaults to -"relay". There are some user names that you don't want relayed, perhaps -because of local aliases. A common example is root, which may be -locally aliased. You can add entries to this list using - - LOCAL_USER(usernames) - -This adds users to class L; you could also use something like - - FL/etc/sendmail.cL - -If you want all incoming mail sent to a centralized hub, as for a -shared /var/spool/mail scheme, use - - define(`MAIL_HUB', mailer:hostname) - -Again, ``mailer:'' defaults to "relay". If you define both LOCAL_RELAY -and MAIL_HUB _AND_ you have FEATURE(stickyhost), unqualified names will -be sent to the LOCAL_RELAY and other local names will be sent to MAIL_HUB. -Names in $=L will be delivered locally, so you MUST have aliases or -.forward files for them. - -For example, if you are on machine mastodon.CS.Berkeley.EDU and you have -FEATURE(stickyhost), the following combinations of settings will have the -indicated effects: - -email sent to.... eric eric@mastodon.CS.Berkeley.EDU - -LOCAL_RELAY set to mail.CS.Berkeley.EDU (delivered locally) -mail.CS.Berkeley.EDU (no local aliasing) (aliasing done) - -MAIL_HUB set to mammoth.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU -mammoth.CS.Berkeley.EDU (aliasing done) (aliasing done) - -Both LOCAL_RELAY and mail.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU -MAIL_HUB set as above (no local aliasing) (aliasing done) - -If you do not have FEATURE(stickyhost) set, then LOCAL_RELAY and -MAIL_HUB act identically, with MAIL_HUB taking precedence. - -If you want all outgoing mail to go to a central relay site, define -SMART_HOST as well. Briefly: - - LOCAL_RELAY applies to unqualifed names (e.g., "eric"). - MAIL_HUB applies to names qualified with the name of the - local host (e.g., "eric@mastodon.CS.Berkeley.EDU"). - SMART_HOST applies to names qualified with other hosts. - -However, beware that other relays (e.g., UUCP_RELAY, BITNET_RELAY, -DECNET_RELAY, and FAX_RELAY) take precedence over SMART_HOST, so if you -really want absolutely everything to go to a single central site you will -need to unset all the other relays -- or better yet, find or build a -minimal config file that does this. - -For duplicate suppression to work properly, the host name is best -specified with a terminal dot: - - define(`MAIL_HUB', `host.domain.') - note the trailing dot ---^ - - -+--------------------------------+ -| ADDING NEW MAILERS OR RULESETS | -+--------------------------------+ - -Sometimes you may need to add entirely new mailers or rulesets. They -should be introduced with the constructs MAILER_DEFINITIONS and -LOCAL_RULESETS respectively. For example: - - MAILER_DEFINITIONS - Mmymailer, ... - ... - - LOCAL_RULESETS - Scheck_relay - ... - - -+-------------------------------+ -| NON-SMTP BASED CONFIGURATIONS | -+-------------------------------+ - -These configuration files are designed primarily for use by SMTP-based -sites. I don't pretend that they are well tuned for UUCP-only or -UUCP-primarily nodes (the latter is defined as a small local net -connected to the rest of the world via UUCP). However, there is one -hook to handle some special cases. - -You can define a ``smart host'' that understands a richer address syntax -using: - - define(`SMART_HOST', mailer:hostname) - -In this case, the ``mailer:'' defaults to "relay". Any messages that -can't be handled using the usual UUCP rules are passed to this host. - -If you are on a local SMTP-based net that connects to the outside -world via UUCP, you can use LOCAL_NET_CONFIG to add appropriate rules. -For example: - - define(`SMART_HOST', suucp:uunet) - LOCAL_NET_CONFIG - R$* < @ $* .$m. > $* $#smtp $@ $2.$m. $: $1 < @ $2.$m. > $3 - -This will cause all names that end in your domain name ($m) via -SMTP; anything else will be sent via suucp (smart UUCP) to uunet. -If you have FEATURE(nocanonify), you may need to omit the dots after -the $m. If you are running a local DNS inside your domain which is -not otherwise connected to the outside world, you probably want to -use: - - define(`SMART_HOST', smtp:fire.wall.com) - LOCAL_NET_CONFIG - R$* < @ $* . > $* $#smtp $@ $2. $: $1 < @ $2. > $3 - -That is, send directly only to things you found in your DNS lookup; -anything else goes through SMART_HOST. - - -+-----------+ -| WHO AM I? | -+-----------+ - -Normally, the $j macro is automatically defined to be your fully -qualified domain name (FQDN). Sendmail does this by getting your -host name using gethostname and then calling gethostbyname on the -result. For example, in some environments gethostname returns -only the root of the host name (such as "foo"); gethostbyname is -supposed to return the FQDN ("foo.bar.com"). In some (fairly rare) -cases, gethostbyname may fail to return the FQDN. In this case -you MUST define confDOMAIN_NAME to be your fully qualified domain -name. This is usually done using: - - Dmbar.com - define(`confDOMAIN_NAME', `$w.$m')dnl - - -+--------------------+ -| USING MAILERTABLES | -+--------------------+ - -To use FEATURE(mailertable), you will have to create an external -database containing the routing information for various domains. -For example, a mailertable file in text format might be: - - .my.domain xnet:%1.my.domain - uuhost1.my.domain suucp:uuhost1 - .bitnet smtp:relay.bit.net - -This should normally be stored in /etc/mailertable. The actual -database version of the mailertable is built using: - - makemap hash /etc/mailertable.db < /etc/mailertable - -The semantics are simple. Any LHS entry that does not begin with -a dot matches the full host name indicated. LHS entries beginning -with a dot match anything ending with that domain name -- that is, -they can be thought of as having a leading "*" wildcard. Matching -is done in order of most-to-least qualified -- for example, even -though ".my.domain" is listed first in the above example, an entry -of "uuhost1.my.domain" will match the second entry since it is -more explicit. - -The RHS should always be a "mailer:host" pair. The mailer is the -configuration name of a mailer (that is, an `M' line in the -sendmail.cf file). The "host" will be the hostname passed to -that mailer. In domain-based matches (that is, those with leading -dots) the "%1" may be used to interpolate the wildcarded part of -the host name. For example, the first line above sends everything -addressed to "anything.my.domain" to that same host name, but using -the (presumably experimental) xnet mailer. - -In some cases you may want to temporarily turn off MX records, -particularly on gateways. For example, you may want to MX -everything in a domain to one machine that then forwards it -directly. To do this, you might use the DNS configuration: - - *.domain. IN MX 0 relay.machine - -and on relay.machine use the mailertable: - - .domain smtp:[gateway.domain] - -The [square brackets] turn off MX records for this host only. -If you didn't do this, the mailertable would use the MX record -again, which would give you an MX loop. - - -+--------------------------------+ -| USING USERDB TO MAP FULL NAMES | -+--------------------------------+ - -The user database was not originally intended for mapping full names -to login names (e.g., Eric.Allman => eric), but some people are using -it that way. (I would recommend that you set up aliases for this -purpose instead -- since you can specify multiple alias files, this -is fairly easy.) The intent was to locate the default maildrop at -a site, but allow you to override this by sending to a specific host. - -If you decide to set up the user database in this fashion, it is -imperative that you not use FEATURE(stickyhost) -- otherwise, -e-mail sent to Full.Name@local.host.name will be rejected. - -To build the internal form of the user database, use: - - makemap btree /usr/data/base.db < /usr/data/base.txt - -As a general rule, I am adamantly opposed to using full names as -e-mail addresses, since they are not in any sense unique. For example, -the Unix software-development community has two Andy Tannenbaums, -at least two well-known Peter Deutsches, and at one time Bell Labs -had two Stephen R. Bournes with offices along the same hallway. -Which one will be forced to suffer the indignity of being -Stephen_R_Bourne_2? The less famous of the two, or the one that -was hired later? - -Finger should handle full names (and be fuzzy). Mail should use -handles, and not be fuzzy. [Not that I expect anyone to pay any -attention to my opinions.] - - -+--------------------------------+ -| MISCELLANEOUS SPECIAL FEATURES | -+--------------------------------+ - -Plussed users - Sometimes it is convenient to merge configuration on a - centralized mail machine, for example, to forward all - root mail to a mail server. In this case it might be - useful to be able to treat the root addresses as a class - of addresses with subtle differences. You can do this - using plussed users. For example, a client might include - the alias: - - root: root+client1@server - - On the server, this will match an alias for "root+client1". - If that is not found, the alias "root+*" will be tried, - then "root". - -LDAP - For notes on use LDAP in sendmail, see - http://www-leland.stanford.edu/~bbense/Inst.html - - - -+----------------+ -| SECURITY NOTES | -+----------------+ - -A lot of sendmail security comes down to you. Sendmail 8 is much -more careful about checking for security problems than previous -versions, but there are some things that you still need to watch -for. In particular: - -* Make sure the aliases file isn't writable except by trusted - system personnel. This includes both the text and database - version. - -* Make sure that other files that sendmail reads, such as the - mailertable, are only writable by trusted system personnel. - -* The queue directory should not be world writable PARTICULARLY - if your system allows "file giveaways" (that is, if a non-root - user can chown any file they own to any other user). - -* If your system allows file giveaways, DO NOT create a publically - writable directory for forward files. This will allow anyone - to steal anyone else's e-mail. Instead, create a script that - copies the .forward file from users' home directories once a - night (if you want the non-NFS-mounted forward directory). - -* If your system allows file giveaways, you'll find that - sendmail is much less trusting of :include: files -- in - particular, you'll have to have /SENDMAIL/ANY/SHELL/ in - /etc/shells before they will be trusted (that is, before - files and programs listed in them will be honored). - -In general, file giveaways are a mistake -- if you can turn them -off I recommend you do so. - - -+--------------------------------+ -| TWEAKING CONFIGURATION OPTIONS | -+--------------------------------+ - -There are a large number of configuration options that don't normally -need to be changed. However, if you feel you need to tweak them, you -can define the following M4 variables. This list is shown in four -columns: the name you define, the default value for that definition, -the option or macro that is affected (either Ox for an option or Dx -for a macro), and a brief description. Greater detail of the semantics -can be found in the Installation and Operations Guide. - -Some options are likely to be deprecated in future versions -- that is, -the option is only included to provide back-compatibility. These are -marked with "*". - -Remember that these options are M4 variables, and hence may need to -be quoted. In particular, arguments with commas will usually have to -be ``double quoted, like this phrase'' to avoid having the comma -confuse things. This is common for alias file definitions and for -the read timeout. - -M4 Variable Name Configuration Description & [Default] -================ ============= ======================= -confMAILER_NAME $n macro [MAILER-DAEMON] The sender name used - for internally generated outgoing - messages. -confDOMAIN_NAME $j macro If defined, sets $j.

This need not be - a full pathname, in which case it is - interpreted relative to the queue - directory. -confSINGLE_THREAD_DELIVERY SingleThreadDelivery - [False] If this option and the - HostStatusDirectory option are both - set, single thread deliveries to other - hosts. That is, don't allow any two - sendmails on this host to connect - simultaneously to any other single - host. This can slow down delivery in - some cases, in particular since a - cached but otherwise idle connection - to a host will prevent other sendmails - from connecting to the other host. -confUSE_ERRORS_TO* UserErrorsTo [False] Use the Errors-To: header to - deliver error messages.

If not set or <= 0, there is - no limit. -confWORK_RECIPIENT_FACTOR - RecipientFactor [30000] Cost of each recipient. -confSEPARATE_PROC ForkEachJob [False] Run all deliveries in a separate - process. -confWORK_CLASS_FACTOR ClassFactor [1800] Priority multiplier for class. -confWORK_TIME_FACTOR RetryFactor [90000] Cost of each delivery attempt. -confQUEUE_SORT_ORDER QueueSortOrder [Priority] Queue sort algorithm: - Priority, Host, or Time. -confMIN_QUEUE_AGE MinQueueAge [0] The minimum amount of time a job - must sit in the queue between queue - runs. This allows you to set the - queue run interval low for better - resposiveness without trying all - jobs in each run. -confDEF_CHAR_SET DefaultCharSet [unknown-8bit] When converting - unlabelled 8 bit input to MIME, the - character set to use by default. -confSERVICE_SWITCH_FILE ServiceSwitchFile - [/etc/service.switch] The file to use - for the service switch on systems that - do not have a system-defined switch. -confHOSTS_FILE HostsFile [/etc/hosts] The file to use when doing - "file" type access of hosts names. -confDIAL_DELAY DialDelay [0s] If a connection fails, wait this - long and try again. Zero means "don't - retry". This is to allow "dial on - demand" connections to have enough time - to complete a connection. -confNO_RCPT_ACTION NoRecipientAction - [none] What to do if there are no legal - recipient fields (To:, Cc: or Bcc:) - in the message. Legal values can - be "none" to just leave the - nonconforming message as is, "add-to" - to add a To: header with all the - known recipients (which may expose - blind recipients), "add-apparently-to" - to do the same but use Apparently-To: - instead of To:, "add-bcc" to add an - empty Bcc: header, or - "add-to-undisclosed" to add the header - ``To: undisclosed-recipients:;''. -confSAFE_FILE_ENV SafeFileEnvironment - [undefined] If set, sendmail will do a - chroot() into this directory before - writing files. -confCOLON_OK_IN_ADDR ColonOkInAddr [True unless Configuration Level > 6] - If set, colons are treated as a regular - character in addresses. If not set, - they are treated as the introducer to - the RFC 822 "group" syntax. Colons are - handled properly in route-addrs. This - option defaults on for V5 and lower - configuration files. -confMAX_QUEUE_RUN_SIZE MaxQueueRunSize [0] If set, limit the maximum size of - any given queue run to this number of - entries. Essentially, this will stop - reading the queue directory after this - number of entries are reached; it does - _not_ pick the highest priority jobs, - so this should be as large as your - system can tolerate. If not set, there - is no limit. -confDONT_EXPAND_CNAMES DontExpandCnames - [False] If set, $[ ... $] lookups that - do DNS based lookups do not expand - CNAME records. This currently violates - the published standards, but the IETF - seems to be moving toward legalizing - this. For example, if "FTP.Foo.ORG" - is a CNAME for "Cruft.Foo.ORG", then - with this option set a lookup of - "FTP" will return "FTP.Foo.ORG"; if - clear it returns "Cruft.FOO.ORG". N.B. - you may not see any effect until your - downstream neighbors stop doing CNAME - lookups as well. -confFROM_LINE UnixFromLine [From $g $d] The From_ line used - when sending to files or programs. -confOPERATORS OperatorChars [.:%@!^/[]+] Address operator - characters. -confSMTP_LOGIN_MSG SmtpGreetingMessage - [$j Sendmail $v/$Z; $b] - The initial (spontaneous) SMTP - greeting message. The word "ESMTP" - will be inserted between the first and - second words to convince other - sendmails to try to speak ESMTP. -confDONT_INIT_GROUPS DontInitGroups [False] If set, the initgroups(3) - routine will never be invoked. You - might want to do this if you are - running NIS and you have a large group - map, since this call does a sequential - scan of the map; in a large site this - can cause your ypserv to run - essentially full time. If you set - this, agents run on behalf of users - will only have their primary - (/etc/passwd) group permissions. -confUNSAFE_GROUP_WRITES UnsafeGroupWrites - [False] If set, group-writable - :include: and .forward files are - considered "unsafe", that is, programs - and files cannot be directly referenced - from such files. World-writable files - are always considered unsafe. -confDOUBLE_BOUNCE_ADDRESS DoubleBounceAddress - [postmaster] If an error occurs when - sending an error message, send that - "double bounce" error message to this - address. -confRUN_AS_USER RunAsUser [undefined] If set, become this user - when reading and delivering mail. - Causes all file reads (e.g., .forward - and :include: files) to be done as - this user. Also, all programs will - be run as this user, and all output - files will be written as this user. - Intended for use only on firewalls - where users do not have accounts. - -See also the description of OSTYPE for some parameters that can be -tweaked (generally pathnames to mailers). - - -+-----------+ -| HIERARCHY | -+-----------+ - -Within this directory are several subdirectories, to wit: - -m4 General support routines. These are typically - very important and should not be changed without - very careful consideration. - -cf The configuration files themselves. They have - ".mc" suffixes, and must be run through m4 to - become complete. The resulting output should - have a ".cf" suffix. - -ostype Definitions describing a particular operating - system type. These should always be referenced - using the OSTYPE macro in the .mc file. Examples - include "bsd4.3", "bsd4.4", "sunos3.5", and - "sunos4.1". - -domain Definitions describing a particular domain, referenced - using the DOMAIN macro in the .mc file. These are - site dependent; for example, "CS.Berkeley.EDU.m4" - describes hosts in the CS.Berkeley.EDU subdomain. - -mailer Descriptions of mailers. These are referenced using - the MAILER macro in the .mc file. - -sh Shell files used when building the .cf file from the - .mc file in the cf subdirectory. - -feature These hold special orthogonal features that you might - want to include. They should be referenced using - the FEATURE macro. - -hack Local hacks. These can be referenced using the HACK - macro. They shouldn't be of more than voyeuristic - interest outside the .Berkeley.EDU domain, but who knows? - We've all got our own peccadillos. - -siteconfig Site configuration -- e.g., tables of locally connected - UUCP sites. - - -+------------------------+ -| ADMINISTRATIVE DETAILS | -+------------------------+ - -The following sections detail usage of certain internal parts of the -sendmail.cf file.

It will keep -doing this until no further expansion is possible. -.SH OPTIONS -The default output of -.B expn -can contain many lines which are not valid -email addresses. With the -.I -aa -flag, only expansions that result in legal addresses -are used. Since many mailing lists have an illegal -address or two, the single -.IR -a , -address, flag specifies that a few illegal addresses can -be mixed into the results. More -.I -a -flags vary the ratio. Read the source to track down -the formula. With the -.I -a -option, you should be able to construct a new mailing -list out of an existing one. -.LP -If you wish to limit the number of levels deep that -.B expn -will recurse as it traces addresses, use the -.I -1 -option. For each -.I -1 -another level will be traversed. So, -.I -111 -will traverse no more than three levels deep. -.LP -The normal mode of operation for -.B expn -is to do all of its work silently. -The following options make it more verbose. -It is not necessary to make it verbose to see what it is -doing because as it works, it changes its -.BR argv [0] -variable to reflect its current activity. -To see how it is expanding things, the -.IR -v , -verbose, flag will cause -.B expn -to show each address before -and after translation as it works. -The -.IR -w , -watch, flag will cause -.B expn -to show you its conversations with the mail daemons. -Finally, the -.IR -d , -debug, flag will expose many of the inner workings so that -it is possible to eliminate bugs. -.SH ENVIRONMENT -No enviroment variables are used. -.SH FILES -.PD 0 -.B /tmp/expn$$ -.B temporary file used as input to -.BR nslookup . -.SH SEE ALSO -.BR aliases (5), -.BR sendmail (8), -.BR nslookup (8), -RFC 823, and RFC 1123. -.SH BUGS -Not all mail daemons will implement -.B expn -or -.BR vrfy . -It is not possible to verify addresses that are served -by such daemons. -.LP -When attempting to connect to a system to verify an address, -.B expn -only tries one IP address. Most mail daemons -will try harder. -.LP -It is assumed that you are running domain names and that -the -.BR nslookup (8) -program is available. If not, -.B expn -will not be able to verify many addresses. It will also pause -for a long time unless you change the code where it says -.I $have_nslookup = 1 -to read -.I $have_nslookup = -.IR 0 . -.LP -Lastly, -.B expn -does not handle every valid address. If you have an example, -please submit a bug report. -.SH CREDITS -In 1986 or so, Jon Broome wrote a program of the same name -that did about the same thing. It has since suffered bit rot -and Jon Broome has dropped off the face of the earth! -(Jon, if you are out there, drop me a line) -.SH AVAILABILITY -The latest version of -.B expn -is available through anonymous ftp at -.IR ftp://ftp.idiom.com/pub/muir-programs/expn . -.SH AUTHOR -.I David Muir Sharnoff\ \ \ \ diff --git a/usr.sbin/sendmail/contrib/mailprio b/usr.sbin/sendmail/contrib/mailprio deleted file mode 100644 index 58feba7c22e4..000000000000 --- a/usr.sbin/sendmail/contrib/mailprio +++ /dev/null @@ -1,557 +0,0 @@ -Received: from austin.bsdi.com (root{9l9gVDC7v8t3dlv0OtXTlby6X1zBWd56}@austin.BSDI.COM [205.230.224.49]) by knecht.Sendmail.ORG (8.8.2/8.8.2) with ESMTP id JAA05023 for ; Thu, 31 Oct 1996 09:29:47 -0800 (PST) -Received: from austin.bsdi.com (localhost [127.0.0.1]) by austin.bsdi.com (8.7.4/8.7.3) with ESMTP id KAA19250; Thu, 31 Oct 1996 10:28:18 -0700 (MST) -Message-Id: <199610311728.KAA19250@austin.bsdi.com> -To: Eric Allman -cc: marc@xfree86.org -Subject: Updated mailprio_0_93.shar -From: Tony Sanders -Organization: Berkeley Software Design, Inc. -Date: Thu, 31 Oct 1996 10:28:14 -0700 -Sender: sanders@austin.bsdi.com - -Eric, please update contrib/mailprio in the sendmail distribution -to this version at your convenience.

MIME) -[RFC1521, RFC1344]. -Neither the IDA group nor most vendors -were modifying -.i sendmail -to conform to these new standards. -It seemed clear that these were ``good things'' -that should be encouraged. -However, since no one was working on a publically available version of -.i sendmail -with these updates, -they were unlikely to be widely deployed any time in the near future. -.pp -There are, of course, other mail transport agents available, -such as -.i MMDF -.\"[ref], -.i zmailer -.\"[ref], -.i smail -.\"[ref], -and -.i PP -.\"[ref]. -However, none of these seemed to be gaining the prominence of -.i sendmail ; -it appeared that most companies would not convert to another -mail transport agent any time in the forseeable future. -However, they might be persuaded to convert to a newer version of -.i sendmail . -.pp -All of these convinced the author -to work on a updated version of -.i sendmail -for public distribution. -.pp -The new version of -.i sendmail -is referred to as version eight (V8). -Versions six and seven were skipped -because of an agreement -that all files in 4.4BSD would be numbered as -.q 8.1 . -Rather than have an external version number -that differed from the file version numbers, -.i sendmail -just jumped directly to V8. -.sh 1 "CHANGES IN VERSION EIGHT" -.pp -The following is a summary of the changes between the last commonly -available version of sendmail from Berkeley (5.67) and the latest -version (8.6.6). -.pp -Many of these are ideas that had been tried in IDA, -but many of them were generalized in V8. -.sh 2 "Performance Enhancements" -.pp -Instead of closing SMTP connections immediately, open connections are -cached for possible future use. There is a limit to the number of -simultaneous open connections and the idle time of any individual -connection. -.pp -This is of best help during queue processing (since there is the -potential of many different messages going to one site), although -it can also help when processing MX records which aren't handled -by MX Piggybacking. -.pp -If two hosts with different names in a single message happen to -have the same set of MX hosts, they can be sent in the same -transaction. Version 8 notices this and tries to batch the messages. -.pp -For example, if two sites ``foo.com'' and ``bar.com'' are both -served by UUNET, they will have the same set of MX hosts and will -be sent in one transaction. UUNET will then split the message -and send it to the two individual hosts. -.sh 2 "RFC 1123 Changes" -.pp -A number of changes have been made to make sendmail ``conditionally -compliant'' (that is, it satisfies all of the MUST clauses and most -but not all of the SHOULD clauses in RFC 1123). -.pp -The major areas of change are (numbers are RFC 1123 section numbers): -.nr ii 0.75i -.ip \(sc5.2.7 -Response to RCPT command is fast. Previously, sendmail -expanded all aliases as far as it could \*- this could -take a very long time, particularly if there were -name server delays. Version 8 only checks for the -existence of an alias and does the expansion later. -It does still do a DNS lookup if there is an explicit host name -in the RCPT command, -but this time is bounded. -.ip \(sc5.2.8 -Numeric IP addresses are logged in Received: lines. -This helps tracing spoofed messages. -.ip \(sc5.2.17 -Self domain literal is properly handled. Previously, -if someone sent to user@[1.2.3.4], where 1.2.3.4 is -your IP address, the mail would probably be rejected -with a ``configuration error''. -Version 8 can handle these addresses. -.ip \(sc5.3.2 -Better control over individual timeouts. RFC 821 specified -no timeouts. Older versions of sendmail had a single -timeout, typically set to two hours. Version 8 allows -the configuration file to set timeouts for various -SMTP commands individually. -.ip \(sc5.3.3 -Error messages are sent as From:<>. This was urged by -RFC 821 and reiterated by RFC 1123, but older versions -of sendmail never really did it properly. Version 8 -does. However, some systems cannot handle this -perfectly legal address; if necessary, you can create -a special mailer that uses the `g' flag to disable this. -.ip \(sc5.3.3 -Error messages are never sent to <>. Previously, -sendmail was happy to send responses-to-responses which -sometimes resulted in responses-to-responses-to-responses -which resulted in .... you get the idea. -.ip \(sc5.3.3 -Route-addrs (the ugly ``<@hosta,@hostb:user@hostc>'' -syntax) are pruned. RFC 821 urged the use of this -bletcherous syntax. RFC 1123 has seen the light and -officially deprecates them, further urging that you -eliminate all but ``user@hostc'' should you receive -one of these things. Version 8 is slightly more generous -than the standards suggest; instead of stripping off all -the route addressees, it only strips hosts off up to -the one before the last one known to DNS, thus allowing -you to have pseudo-hosts such as foo.BITNET. The `R' -option will turn this off. -.lp -The areas in which sendmail is not ``unconditionally compliant'' are: -.ip \(sc5.2.6 -Sendmail does do header munging. -.ip \(sc5.2.10 -Sendmail doesn't always use the exact SMTP message -text from RFC 821. This is a rather silly requirement. -.ip \(sc5.3.1.1 -Sendmail doesn't guarantee only one connect for each -host on queue runs. Connection caching gives you most -of this, but it does not provide a guarantee. -.ip \(sc5.3.1.1 -Sendmail doesn't always provide an adequate limit -on concurrency. That is, there can be several -independent sendmails running at once. My feeling -is that doing an absolute limit would be a mistake -(it might result in lost mail). However, if you use -the XLA contributed software, most of this will be -guaranteed (but I don't guarantee the guarantee). -.sh 2 "Extended SMTP Support -.pp -Version 8 includes both sending and receiving support for Extended -SMTP support as defined by RFC 1425 (basic) and RFC 1427 (SIZE); -and limited support for RFC 1426 (BODY). -The body support is minimal because the -.q 8BITMIME -body type is not currently advertised. -Although such a body type will be accepted, -it will not be correctly converted to 7 bits -if speaking to a non-8-bit-MIME aware SMTP server. -.pp -.i Sendmail -tries to speak ESMTP if you have the `a' flag set -in the flags for the mailer descriptor, -or if the other end advertises the fact that it speaks ESMTP. -This is a non-standard advertisement: -.i sendmail -announces -.q "ESMTP spoken here" -during the initial connection message, -and client sendmails search for this message. -This creates some problems for some PC-based mailers, -which do not understand two-line greeting messages -as required by RFC 821. -.sh 2 "Eight-Bit Clean -.pp -Previous versions of sendmail used the 0200 bit for quoting. This -version avoids that use. -However, you can set option `7' to get seven bit stripping -for compatibility with RFC 821, -which is a 7-bit protocol. -This option says ``strip to 7 bits on input''. -.pp -Individual mailers can still produce seven bit out put using the -`7' mailer flag. -This flag says ``strip to 7 bits on output''. -.sh 2 "User Database" -.pp -The User Database (UDB) is an as-yet experimental attempt to provide -unified large-site name support. -We are installing it at Berkeley; -future versions may show significant modifications. -Briefly, UDB contains a database that is intended to contain -all the per-user information for your workgroup, -such as people's full names, their .plan information, -their outgoing mail name, and their mail drop. -.pp -The user database allows you to map both incoming and outgoing -addresses, much like IDA. However, the interface is still -better with IDA; -in particular, the alias file with incoming/outgoing marks -provides better locality of information. -.sh 2 "Improved BIND Support" -.pp -The BIND support, particularly for MX records, had a number of -annoying ``features'' which have been removed in this release. In -particular, these more tightly bind (pun intended) the name server -to sendmail, so that the name server resolution rules are incorporated -directly into sendmail. -.pp -The major change has been that the $[ ... $] operator didn't fully -qualify names that were in DNS as A or MX records. Version 8 does -this qualification. -.pp -This has proven to be an annoyance in Sun shops, -who often still run without BIND support. -However, it is really critical that this be supported, -since MX records are mandatory. -In SunOS you can choose either MX support or NIS support, -but not both. -This is fixed in Solaris, -and some -.i sendmail -support to allow this in SunOS should be forthcoming in a future release. -.sh 2 "Keyed Files" -.pp -Generalized keyed files is an idea taken directly from IDA sendmail -(albeit with a completely different implementation). -They can be useful on large sites. -.pp -Version 8 includes the following built-in map classes: -.ip dbm -Support for the ndbm(3) library. -.ip hash -Support for the ``Hash'' type from the new Berkeley db(3) library. -this library provides substantially better database support -than ndbm(3), -including in-memory caching, -arbitrarily long keys and values, -and better disk utilization. -.ip btree -Support for the ``B-Tree'' type from the new Berkeley db(3) library. -B-Trees provide better clustering than Hashed files -if you are fetching lots of records that have similar keys, -such as searching a dictionary for words beginning with ``detr''. -.ip nis -Support for NIS (a.k.a. YP) maps. -NIS+ is not supported in this version. -.ip host -Support for DNS lookups. -.ip dequote -A ``pseudo-map'' (that is, once that does not have any external data) -that allows a configuration file to break apart a quoted string -in the address. -This is necessary primarily for DECnet addresses, -which often have quoted addresses that need to be unwrapped on gateways. -.sh 2 "Multi-Word Classes & Macros in Classes" -.pp -Classes can now be multiple words. For example, -.(b -CShofmann.CS.Berkeley.EDU -.)b -allows you to match the entire string ``hofmann.CS.Berkeley.EDU'' -using the single construct ``$=S''. -.pp -Class definitions are now allowed to include macros \*- for example: -.(b -Cw$k -.)b -is legal. -.sh 2 "IDENT Protocol Support" -.pp -The IDENT protocol as defined in RFC 1413 [RFC1413] is supported. -However, many systems have a TCP/IP bug that renders this useless, -and the feature must be turned off. -Roughly, if one of these system receives a -.q "No route to host" -message (ICMP message ICMP_UNREACH_HOST) on -.i any -connection, all connections to that host are closed. -Some firewalls return this error if you try to connect -to the IDENT port, -so you can't receive email from these hosts on these systems. -It's possible that if the firewall used a more specific message -(such as ICMP_UNREACH_PROTOCOL, ICMP_UNREACH_PORT or ICMP_UNREACH_NET_PROHIB) -it would work, but this hasn't been verified. -.pp -IDENT protocol support cannot be used on -4.3BSD, -Apollo DomainOS, -Apple A/UX, -ConvexOS, -Data General DG/UX, -HP-UX, -Sequent Dynix, -or -Ultrix 4.x, x \(<= 3. -It seems to work on -4.4BSD, -IBM AIX 3.x, -OSF/1, -SGI IRIX, -Solaris, -SunOS, -and Ultrix 4.4. -.sh 2 "Separate Envelope/Header Processing -.pp -Since the From: line is passed in separately from the envelope -sender, these have both been made visible; the $g macro is set to -the envelope sender during processing of mailer argument vectors -and the header sender during processing of headers. -.pp -It is also possible to specify separate per-mailer envelope and -header processing. The SenderRWSet and RecipientRWset arguments -for mailers can be specified as ``envelope/header'' to give different -rewritings for envelope versus header addresses. -.sh 2 "Owner-List Propagates to Envelope -.pp -When an alias has an associated owner-list name, that alias is used -to change the envelope sender address. This will cause downstream -errors to be returned to that owner. -.pp -Some people find this confusing -because the envelope sender is what appears in the first -``From_'' line in UNIX messages -(that is, the line beginning ``From'' -instead of ``From:''; -the latter is the header from, which -.i does -indicate the sender of the message). -In previous versions, -.i sendmail -has tried to avoid changing the envelope sender -for back compatibility with UNIX convention; -at this point that back compatibility is creating too many problems, -and it is necessary to move forward into the 1980s. -.sh 2 "Command Line Flags" -.pp -The -.b \-B -flag has been added to pass in body type information. -.pp -The -.b \-p -flag has been added to pass in protocol information -that was previously passed in by defining the -.b $r -and -.b $s -macros. -.pp -The -.b \-X -flag has been added to allow logging of all protocol in and -out of sendmail for debugging. -You can set -.q "\-X filename" -and a complete transcript will be logged in that file. -This gets big fast: the option is only for debugging. -.pp -The -.b \-q -flag can limit limit a queue run to specific recipients, -senders, or queue ids using \-qRsubstring, \-qSsubstring, or -\-qIsubstring respectively. -.sh 2 "New Configuration Line Types -.pp -The `T' (Trusted users) configuration line has been deleted. It -will still be accepted but will be ignored. -.pp -The `K' line has been added to declare database maps. -.pp -The `V' line has been added to declare the configuration version -level. -.pp -The `M' (mailer) line takes a D= field to specify execution -directory. -.sh 2 "New and Extended Options" -.pp -Several new options have been added, many to support new features, -others to allow tuning that was previously available only by -recompiling. Briefly: -.nr ii 0.5i -.ip A -The alias file specification can now be a list of alias files. -Also, the configuration can specify a class of file. -For example, to search the NIS aliases, use -.q OAnis:mail.aliases . -.ip b -Insist on a minimum number of disk blocks. -.ip C -Delivery checkpoint interval. Checkpoint the queue (to avoid -duplicate deliveries) every C addresses. -.ip E -Default error message. This message (or the contents of the -indicated file) are prepended to error messages. -.ip G -Enable GECOS matching. If you can't find a local user name -and this option is enabled, do a sequential scan of the passwd -file to match against full names. Previously a compile option. -.ip h -Maximum hop count. Previously this was compiled in. -.ip I -This option has been extended to allow setting of resolver parameters. -.ip j -Send errors in MIME-encapsulated format. -.ip J -Forward file path. Where to search for .forward files \*- defaults -to $HOME/.forward. -.ip k -Connection cache size. The total number of connections that will -be kept open at any time. -.ip K -Connection cache lifetime. The amount of time any connection -will be permitted to sit idle. -.ip l -Enable Errors-To: header. These headers violate RFC 1123; -this option is included to provide back compatibility with -old versions of sendmail. -.ip O -Incoming daemon options (e.g., use alternate SMTP port). -.ip p -Privacy options. These can be used to make your SMTP server -less friendly. -.ip r -This option has been extended to allow finer grained control -over timeouts. -For example, you can set the timeout for SMTP commands individually. -.ip R -Don't prune route-addrs. Normally, if version 8 sees an address -like "<@hostA,@hostB:user@hostC>, sendmail will try to strip off -as much as it can (up to user@hostC) as suggested by RFC 1123. -This option disables that behaviour. -.ip T -The -.q "Return To Sender" -timeout has been extended -to allow specification of a warning message interval, -typically something on the order of four hours. -If a message cannot be delivered in that interval, -a warning message is sent back to the sender -but the message continues to be tried. -.ip U -User database spec. This is still experimental. -.ip V -Fallback ``MX'' host. This can be thought of as an MX host -that applies to all addresses that has a very high preference -value (that is, use it only if everything else fails). -.ip w -If set, assume that if you are the best MX host for a host, -you should send directly to that host. This is intended -for compatibility with UIUC sendmail, and may have some -use on firewalls. -.ip 7 -Do not run eight bit clean. Technically, you have to assert -this option to be RFC 821 compatible. -.sh 2 "New Mailer Definitions" -.ip L= -Set the allowable line length. In V5, the L mailer flag implied -a line length limit of 990 characters; this is now settable to -an arbitrary value. -.ip F=a -Try to use ESMTP. It will fall back to SMTP if the initial -EHLO packet is rejected. -.ip F=b -Ensure a blank line at the end of messages. Useful on the -*file* mailer. -.ip F=c -Strip all comments from addresses; this should only be used as -a last resort when dealing with cranky mailers. -.ip F=g -Never use the null sender as the envelope sender, even when -running SMTP. This violates RFC 1123. -.ip F=7 -Strip all output to this mailer to 7 bits. -.ip F=L -Used to set the line limit to 990 bytes for SMTP compatibility. -It now does that only if the L= keyletter is not specified. -This flag is obsolete and should not be used. -.sh 2 "New or Changed Pre-Defined Macros" -.ip $k -UUCP node name from uname(2). -.ip $m -Domain part of our full hostname. -.ip $_ -RFC 1413-provided sender address. -.ip $w -Previously was sometimes the full domain name, sometimes -just the first word. Now guaranteed to be the first word -of the domain name (i.e., the host name). -.ip $j -Previously had to be defined \*- it is now predefined to be -the full domain name, if that can be determined. That is, -it is equivalent to $w.$m. -.sh 2 "New and Changed Classes" -.ip $=k -Initialized to contain $k. -.ip $=w -Now includes -.q [1.2.3.4] -(where 1.2.3.4 is your IP address) -to allow the configuration file to recognize your own IP address. -.sh 2 "New Rewriting Tokens" -.pp -The -.b $& -construct has been adopted from IDA to defer macro evaluation. -Normally, macros in rulesets are bound when the rule is first parsed -during startup. -Some macros change during processing and are uninteresting during startup. -However, that macro can be referenced using -.q $&x -to defer the evaulation of -$x -until the rule is processed. -.pp -The tokens -.b $( -and -.b $) -have been added to allow specification of map rewriting. -.pp -Version 8 allows -.b $@ -on the Left Hand Side of an `R' line to match -zero tokens. -This is intended to be used to match the null input. -.sh 2 "Bigger Defaults -.pp -Version 8 allows up to 100 rulesets instead of 30. It is recommended -that rulesets 0\-9 be reserved for sendmail's dedicated use in future -releases. -.pp -The total number of MX records that can be used has been raised to -20. -.pp -The number of queued messages that can be handled at one time has -been raised from 600 to 1000. -.sh 2 "Different Default Tuning Parameters -.pp -Version 8 has changed the default parameters for tuning queue costs -to make the number of recipients more important than the size of -the message (for small messages). This is reasonable if you are -connected with reasonably fast links. -.sh 2 "Auto-Quoting in Addresses -.pp -Previously, the ``Full Name '' syntax would generate -incorrect protocol output if ``Full Name'' had special characters -such as dot. This version puts quotes around such names. -.sh 2 "Symbolic Names On Error Mailer -.pp -Several names have been built in to the $@ portion of the $#error -mailer. For example: -.(b -$#error $@NOHOST $: Host unknown -.)b -Prints the indicated message -and sets the exit status of -.i sendmail -to -.sm EX_NOHOST . -.sh 2 "New Built-In Mailers" -.pp -Two new mailers, *file* and *include*, are included to define options -when mailing to a file or a :include: file respectively. Previously -these were overloaded on the local mailer. -.sh 2 "SMTP VRFY Doesn't Expand -.pp -Previous versions of sendmail treated VRFY and EXPN the same. In -this version, VRFY doesn't expand aliases or follow .forward files. -.pp -As an optimization, if you run with your default delivery mode -being queue-only, the RCPT command will also not chase aliases and -\&.forward files. -It will chase them when it processes the queue. -This speeds up RCPT processing. -.sh 2 "[IPC] Mailers Allow Multiple Hosts -.pp -When an address resolves to a mailer that has ``[IPC]'' as its -``Path'', the $@ part (host name) can be a colon-separated list of -hosts instead of a single hostname. This asks sendmail to search -the list for the first entry that is available exactly as though -it were an MX record. The intent is to route internal traffic -through internal networks without publishing an MX record to the -net. MX expansion is still done on the individual items. -.sh 2 "Aliases Extended" -.pp -The implementation has been merged with maps. Among other things, -this supports multiple alias files and NIS-based aliases. For -example: -.(b -OA/etc/aliases,nis:mail.aliases -.)b -will search first the local database -.q /etc/aliases -followed by the NIS map - -.sh 2 "Portability and Security Enhancements -.pp -A number of internal changes have been made to enhance portability. -.pp -Several fixes have been made to increase the paranoia factor. -.pp -In particular, the permissions required for .forward and :include: -files have been tightened up considerably. V5 would pretty much -read any file it could get to as root, which exposed some security -holes. V8 insists that all directories leading up to the .forward -or :include: file be searchable ("x" permission) by the controlling -user" (defined below), that the file itself be readable by the -controlling user, and that .forward files be owned by the user -who is being forwarded to or root. -.pp -The "controlling user" is the user on whose behalf the mail is -being delivered. For example, if you mail to "user1" then the -controlling user for ~user1/.forward and any mailers invoked -by that .forward file, including :include: files. -.pp -Previously, anyone who had a home directory could create a .forward -could forward to a program. Now, sendmail checks to make sure -that they have an "approved shell", that is, a shell listed in -the /etc/shells file. -.sh 2 "Miscellaneous Fixes and Enhancements" -.pp -A number of small bugs having to do with things like backslash-escaped -quotes inside of comments have been fixed. -.pp -The fixed size limit on header lines -(such as -.q To: -and -.q Cc: ) -has been eliminated; -those buffers are dynamically allocated now. -.pp -Sendmail writes a /etc/sendmail.pid file with the current process id -and the current invocation flags. -.pp -Two people using the same program (e.g., submit) are considered -"different" so that duplicate elimination doesn't delete one of -them. For example, two people forwarding their email to -|submit will be treated as two recipients. -.pp -The mailstats program prints mailer names and gets the location of -the sendmail.st file from /etc/sendmail.cf. -.pp -Many minor bugs have been fixed, such as handling of backslashes -inside of quotes. -.pp -A hook has been added to allow rewriting of local addresses after -aliasing. -.sh 1 "FUTURE WORK" -.pp -The previous section describes -.i sendmail -as of version 8.6.6. -There is still much to be done. -Some high points are described below. -This list is by no means exhaustive. -.sh 2 "Full MIME Support" -.pp -Currently -.i sendmail -only supports seven bit MIME messages. -Although it can pass eight bit MIME messages, -it cannot advertise that fact because the standards say -that the mail agent must be able to do 8- to 7-bit conversion -to have full 8-bit support. -This requires far more extensive modification of the message body -than is currently supported. -.pp -The best way to do this would be to support the general concept -of an external -``message filter'' -that could do arbitrary modifications of the message. -This would allow MIME conversion as well as such things as -automatic encryption of messages sent over external links. -This is probably an extremely non-trivial change. -.sh 2 "Service Switch Abstraction" -.pp -Most modern systems include some concept of a -.q "service switch" -\*- for example, to look up host names you can try -DNS, NIS, NIS+, text tables, NetInfo, -or other services in some arbitrary order. -This is currently very clumsy in -.i sendmail , -with only limited control of the services provided. -.sh 2 "More Control of Local Addresses" -.pp -Currently some addresses are declared as -.q local -and are handled specially \*- -for example, they may have .forward files, -may be translated into program calls or file deliveries, -and so forth. -These should be broken out into separate flags -to allow the local system administrator -to have more fine-grained control over operations. -.sh 2 "More Run-Time Configuration Options" -.pp -There are many options that are configured at compile time, -such as the method of file locking -and the use of the IDENT protocol -[RFC1413]. -These should be transfered to run time -by adding new options. -.pp -Similarly, some options are currently overloaded, -that is, a single option controls more than one thing. -These should probably be broken out into separate options. -.pp -This implies that options will change from single characters -to words. -.sh 2 "More Configuration Control Over Errors" -.pp -Currently, -the configuration file can generate an error message during parsing. -However, -it cannot tweak other operations, -such as issuing a warning message to the system postmaster. -Similarly, -some errors should not be triggered if they are in aliases -during an alias file rebuild, -but should be triggered if that alias is actually used. -.sh 2 "Long Term Host State" -.pp -Currently, -.i sendmail -only remembers host status during a single queue run. -This should be converted to long term status -stored on disk -so it can be shared between instantiations of -.i sendmail . -Entries will have to be timestamped -so they can time out. -This will allow -.i sendmail -to implement exponential backoff on queue runs -on a per-host basis. -.sh 2 "Connection Control" -.pp -Modern networks have different types of connectivity -than the past. -In particular, the rising prominence of dialup IP -has created certain challenges for automated servers. -It is not uncommon to try to make a connection to a host -and have it fail, even though if you tried again it would succeed. -The connection management could be a bit cleverer -to try to adapt to such situations. -.sh 2 "Other Caching" -.pp -When you do an MX record lookup, -the name server automatically returns the IP addresses -of the associated MX servers. -This information is currently ignored, -and another query is done to get this information. -It should be cached to avoid excess name server traffic. -.sh 1 "REFERENCES" -.ip [Allman83a] -.q "Sendmail \*- An Internetwork Mail Router." -E.

-replace it with a blank sheet for double-sided output. -.bp 7 -.sh 1 "BASIC INSTALLATION" -.pp -There are two basic steps to installing -.i sendmail . -The hard part is to build the configuration table. -This is a file that -.i sendmail -reads when it starts up -that describes the mailers it knows about, -how to parse addresses, -how to rewrite the message header, -and the settings of various options. -Although the configuration table is quite complex, -a configuration can usually be built -by adjusting an existing off-the-shelf configuration. -The second part is actually doing the installation, -i.e., creating the necessary files, etc. -.pp -The remainder of this section will describe the installation of -.i sendmail -assuming you can use one of the existing configurations -and that the standard installation parameters are acceptable. -All pathnames and examples -are given from the root of the -.i sendmail -subtree, -normally -.i /usr/src/usr.\*(SD/sendmail -on 4.4BSD. -.pp -If you are loading this off the tape, -continue with the next section. -If you have a running binary already on your system, -you should probably skip to section 1.2. -.sh 2 "Compiling Sendmail" -.pp -All -.i sendmail -source is in the -.i src -subdirectory. -If you are running on a 4.4BSD system, -compile by typing -.q make . -On other systems, you may have to make some other adjustments. -On most systems, -you can do the appropriate compilation by typing -.(b -sh makesendmail -.)b -This will leave the binary in an appropriately named subdirectory. -It works for multiple object versions -compiled out of the same directory. -.sh 3 "Tweaking the Makefile" -.pp -.i Sendmail -supports two different formats -for the local (on disk) version of databases, -notably the -.i aliases -database. -At least one of these should be defined if at all possible. -.nr ii 1i -.ip NDBM -The ``new DBM'' format, -available on nearly all systems around today. -This was the preferred format prior to 4.4BSD. -It allows such complex things as multiple databases -and closing a currently open database. -.ip NEWDB -The new database package from Berkeley. -If you have this, use it. -It allows -long records, -multiple open databases, -real in-memory caching, -and so forth. -You can define this in conjunction with one of the other two; -if you do, -old databases are read, -but when a new database is created it will be in NEWDB format. -As a nasty hack, -if you have NEWDB, NDBM, and NIS defined, -and if the alias file name includes the substring -.q /yp/ , -.i sendmail -will create both new and old versions of the alias file -during a -.i newalias -command. -This is required because the Sun NIS/YP system -reads the DBM version of the alias file. -It's ugly as sin, -but it works. -.lp -If neither of these are defined, -.i sendmail -reads the alias file into memory on every invocation. -This can be slow and should be avoided. -There are also several methods for remote database access: -.ip NIS -Sun's Network Information Services (formerly YP). -.ip NISPLUS -Sun's NIS+ services. -.ip NETINFO -NeXT's NetInfo service. -.ip HESIOD -Hesiod service (from Athena). -.lp -Other compilation flags are set in conf.h -and should be predefined for you -unless you are porting to a new environment. -.sh 3 "Compilation and installation" -.pp -After making the local system configuration described above, -You should be able to compile and install the system. -The script -.q makesendmail -is the best approach on most systems: -.(b -sh makesendmail -.)b -This will use -.i uname (1) -to select the correct Makefile for your environment. -.pp -You may be able to install using -.(b -sh makesendmail install -.)b -This should install the binary in -/usr/\*(SD -and create links from -/usr/\*(SB/newaliases -and -/usr/\*(SB/mailq -to -/usr/\*(SD/sendmail. -On 4.4BSD systems it will also format and install man pages. -.sh 2 "Configuration Files" -.pp -.i Sendmail -cannot operate without a configuration file. -The configuration defines the mail delivery mechanisms understood at this site, -how to access them, -how to forward email to remote mail systems, -and a number of tuning parameters. -This configuration file is detailed -in the later portion of this document. -.pp -The -.i sendmail -configuration can be daunting at first. -The world is complex, -and the mail configuration reflects that. -The distribution includes an m4-based configuration package -that hides a lot of the complexity. -.pp -These configuration files are simpler than old versions -largely because the world has become simpler; -in particular, -text-based host files are officially eliminated, -obviating the need to -.q hide -hosts behind a registered internet gateway. -.pp -These files also assume that most of your neighbors -use domain-based UUCP addressing; -that is, -instead of naming hosts as -.q host!user -they will use -.q host.domain!user . -The configuration files can be customized to work around this, -but it is more complex. -.pp -Our configuration files are processed by -.i m4 -to facilitate local customization; -the directory -.i cf -of the -.i sendmail -distribution directory -contains the source files. -This directory contains several subdirectories: -.nr ii 1i -.ip cf -Both site-dependent and site-independent descriptions of hosts. -These can be literal host names -(e.g., -.q ucbvax.mc ) -when the hosts are gateways -or more general descriptions -(such as -.q "tcpproto.mc" -as a general description of an SMTP-connected host -or -.q "uucpproto.mc" -as a general description of a UUCP-connected host). -Files ending -.b \&.mc -(``Master Configuration'') -are the input descriptions; -the output is in the corresponding -.b \&.cf -file. -The general structure of these files is described below. -.ip domain -Site-dependent subdomain descriptions. -These are tied to the way your organization wants to do addressing. -For example, -.b domain/cs.exposed.m4 -is our description for hosts in the CS.Berkeley.EDU subdomain -that want their individual hostname to be externally visible;

-there will be exactly one of these per message. -Some fields may be omitted if they do not contain interesting information. -Fields are: -.ip from -The envelope sender address. -.ip size -The size of the message in bytes. -.ip class -The class (i.e., numeric precedence) of the message. -.ip pri -The initial message priority (used for queue sorting). -.ip nrcpts -The number of envelope recipients for this message -(after aliasing and forwarding). -.ip msgid -The message id of the message (from the header). -.ip proto -The protocol used to receive this message (e.g., ESMTP or UUCP) -.ip relay -The machine from which it was received. -.lp -There is also one line logged per delivery attempt -(so there can be several per message if delivery is deferred -or there are multiple recipients). -Fields are: -.ip to -A comma-separated list of the recipients to this mailer. -.ip ctladdr -The ``controlling user'', that is, the name of the user -whose credentials we use for delivery. -.ip delay -The total delay between the time this message was received -and the time it was delivered. -.ip xdelay -The amount of time needed in this delivery attempt -(normally indicative of the speed of the connection). -.ip mailer -The name of the mailer used to deliver to this recipient. -.ip relay -The name of the host that actually accepted (or rejected) this recipient. -.ip stat -The delivery status. -.lp -Not all fields are present in all messages; -for example, the relay is not listed for local deliveries. -.sh 3 "Levels" -.pp -If you have -.i syslogd \|(8) -or an equivalent installed, -you will be able to do logging. -There is a large amount of information that can be logged. -The log is arranged as a succession of levels. -At the lowest level -only extremely strange situations are logged. -At the highest level, -even the most mundane and uninteresting events -are recorded for posterity. -As a convention, -log levels under ten -are considered generally -.q useful; -log levels above 64 -are reserved for debugging purposes. -Levels from 11\-64 are reserved for verbose information -that some sites might want. -.pp -A complete description of the log levels -is given in section -.\" XREF -4.6. -.sh 2 "Dumping State" -.pp -You can ask -.i sendmail -to log a dump of the open files -and the connection cache -by sending it a -.sm SIGUSR1 -signal. -The results are logged at -.sm LOG_DEBUG -priority. -.sh 2 "The Mail Queue" -.pp -Sometimes a host cannot handle a message immediately. -For example, it may be down or overloaded, causing it to refuse connections. -The sending host is then expected to save this message in -its mail queue -and attempt to deliver it later. -.pp -Under normal conditions the mail queue will be processed transparently. -However, you may find that manual intervention is sometimes necessary. -For example, -if a major host is down for a period of time -the queue may become clogged. -Although -.i sendmail -ought to recover gracefully when the host comes up, -you may find performance unacceptably bad in the meantime. -.sh 3 "Printing the queue" -.pp -The contents of the queue can be printed -using the -.i mailq -command -(or by specifying the -.b \-bp -flag to -.i sendmail ): -.(b -mailq -.)b -This will produce a listing of the queue id's, -the size of the message, -the date the message entered the queue, -and the sender and recipients. -.sh 3 "Forcing the queue" -.pp -.i Sendmail -should run the queue automatically -at intervals. -The algorithm is to read and sort the queue, -and then to attempt to process all jobs in order. -When it attempts to run the job, -.i sendmail -first checks to see if the job is locked. -If so, it ignores the job. -.pp -There is no attempt to insure that only one queue processor -exists at any time, -since there is no guarantee that a job cannot take forever -to process -(however, -.i sendmail -does include heuristics to try to abort jobs -that are taking absurd amounts of time; -technically, this violates RFC 821, but is blessed by RFC 1123). -Due to the locking algorithm, -it is impossible for one job to freeze the entire queue. -However, -an uncooperative recipient host -or a program recipient -that never returns -can accumulate many processes in your system. -Unfortunately, -there is no completely general way to solve this. -.pp -In some cases, -you may find that a major host going down -for a couple of days -may create a prohibitively large queue. -This will result in -.i sendmail -spending an inordinate amount of time -sorting the queue. -This situation can be fixed by moving the queue to a temporary place -and creating a new queue. -The old queue can be run later when the offending host returns to service. -.pp -To do this, -it is acceptable to move the entire queue directory: -.(b -cd /var/spool -mv mqueue omqueue; mkdir mqueue; chmod 700 mqueue -.)b -You should then kill the existing daemon -(since it will still be processing in the old queue directory) -and create a new daemon. -.pp -To run the old mail queue, -run the following command: -.(b -/usr/\*(SD/sendmail \-oQ/var/spool/omqueue \-q -.)b -The -.b \-oQ -flag specifies an alternate queue directory -and the -.b \-q -flag says to just run every job in the queue. -If you have a tendency toward voyeurism, -you can use the -.b \-v -flag to watch what is going on. -.pp -When the queue is finally emptied, -you can remove the directory: -.(b -rmdir /var/spool/omqueue -.)b -.sh 2 "Disk Based Connection Information" -.pp -.i Sendmail -stores a large amount of information about each remote system it -has connected to in memory. It is now possible to preserve some -of this information on disk as well, by using the -.b HostStatusDirectory -option, so that it may be shared between several invocations of -.i sendmail . -This allows mail to be queued immediately or skipped during a queue run if -there has been a recent failure in connecting to a remote machine. -.pp -Additionally enabling -.b SingleThreadDelivery -has the added effect of single-threading mail delivery to a destination. -This can be quite helpful -if the remote machine is running an SMTP server that is easily overloaded -or cannot accept more than a single connection at a time, -but can cause some messages to be punted to a future queue run. -It also applies to -.i all -hosts, so setting this because you have one machine on site -that runs some software that is easily overrun -can cause mail to other hosts to be slowed down. -If this option is set, -you probably want to set the -.b MinQueueAge -option as well and run the queue fairly frequently; -this will cause hosts that are skipped because another -.i sendmail -instance is talking to it to be tried again soon. -.pp -The disk based host information is stored in a subdirectory of of the -.b mqueue -directory called -.b \&.hoststat \**. -.(f -\**This is the usual value of the -.b HostStatusDirectory -option; -it can, of course, go anywhere you like in your filesystem. -.)f -Removing this directory and its subdirectories has an effect similar to -the -.i purgestat -command and is completely safe. -The information in these directories can -be perused with the -.i hoststat -command, which will indicate the host name, the last access, and the -status of that access. -An asterisk in the left most column indicates that a -.i sendmail -process currently has the host locked for mail delivery. -.pp -The disk based connection information is treated the same way as memory based -connection information for the purpose of timeouts. -By default, information about host failures is valid for 30 minutes. -This can be adjusted with -the -.b Timeout.hoststatus -option. -.pp -The connection information stored on disk may be purged at any time -with the -.i purgestat -command or by invoking sendmail with the -.b \-bH -switch. -The connection information may be viewed with the -.i hoststat -command or by invoking sendmail with the -.b \-bh -switch. -.sh 2 "The Service Switch" -.pp -The implementation of certain system services -such as host and user name lookup -is controlled by the service switch. -If the host operating system supports such a switch -.i sendmail -will use the native version. -Ultrix, Solaris, and DEC OSF/1 are examples of such systems. -.pp -If the underlying operating system does not support a service switch -(e.g., SunOS, HP-UX, BSD) -then -.i sendmail -will provide a stub implementation. -The -.b ServiceSwitchFile -option points to the name of a file that has the service definitions -Each line has the name of a service -and the possible implementations of that service. -For example, the file: -.(b -hosts dns files nis -aliases files nis -.)b -will ask -.i sendmail -to look for hosts in the Domain Name System first. -If the requested host name is not found, -it tries local files, -and if that fails it tries NIS. -Similarly, -when looking for aliases -it will try the local files first -followed by NIS. -.pp -Service switches are not completely integrated. -For example, despite the fact that the host entry listed in the above example -specifies to look in NIS, -on SunOS this won't happen because the system implementation of -.i gethostbyname \|(3) -doesn't understand this. -If there is enough demand -.i sendmail -may reimplement -.i gethostbyname \|(3), -.i gethostbyaddr \|(3), -.i getpwent \|(3), -and the other system routines that would be necessary -to make this work seamlessly. -.sh 2 "The Alias Database" -.pp -After recipient addresses are read from the SMTP connection -or command line -they are parsed by ruleset 0, -which must resolve to a -{\c -.i mailer , -.i host , -.i user } -triple. -If the flags selected by the -.i mailer -includes the -.b A -(aliasable) flag, -the -.i user -part of the triple is looked up as the key -(i.e., the left hand side) -into the alias database -If there is a match, the address is deleted from the send queue -and all addresses on the right hand side of the alias -are added in place of the alias that was found. -This is a recursive operation, -so aliases found in the right hand side of the alias -are similarly expanded. -.pp -The alias database exists in two forms. -One is a text form, -maintained in the file -.i /etc/aliases. -The aliases are of the form -.(b -name: name1, name2, ... -.)b -Only local names may be aliased; -e.g., -.(b -eric@prep.ai.MIT.EDU: eric@CS.Berkeley.EDU -.)b -will not have the desired effect -(except on prep.ai.MIT.EDU, -and they probably don't want me)\**. -.(f -\**Actually, any mailer that has the `A' mailer flag set -will permit aliasing; -this is normally limited to the local mailer. -.)f -Aliases may be continued by starting any continuation lines -with a space or a tab. -Blank lines and lines beginning with a sharp sign -(\c -.q # ) -are comments. -.pp -The second form is processed by the -.i ndbm \|(3)\** -.(f -\**The -.i gdbm -package probably works as well. -.)f -or -.i db \|(3) -library. -This form is in the files -.i /etc/aliases.dir -and -.i /etc/aliases.pag. -This is the form that -.i sendmail -actually uses to resolve aliases. -This technique is used to improve performance. -.pp -The control of search order is actually set by the service switch. -Essentially, the entry -.(b -OAswitch:aliases -.)b -is always added as the first alias entry; -also, the first alias file name without a class -(e.g., without -.q nis: -on the front) -will be used as the name of the file for a ``files'' entry -in the aliases switch. -For example, if the configuration file contains -.(b -OA/etc/aliases -.)b -and the service switch contains -.(b -aliases nis files nisplus -.)b -then aliases will first be searched in the NIS database, -then in /etc/aliases, -then in the NIS+ database. -.pp -You can also use -.sm NIS -based -alias files. -For example, the specification: -.(b -OA/etc/aliases -OAnis:mail.aliases@my.nis.domain -.)b -will first search the /etc/aliases file -and then the map named -.q mail.aliases -in -.q my.nis.domain . -Warning: if you build your own -.sm NIS -based -alias files, -be sure to provide the -.b \-l -flag to -.i makedbm (8) -to map upper case letters in the keys to lower case; -otherwise, aliases with upper case letters in their names -won't match incoming addresses. -.pp -Additional flags can be added after the colon -exactly like a -.b K -line \(em for example: -.(b -OAnis:\-N mail.aliases@my.nis.domain -.)b -will search the appropriate NIS map and always include null bytes in the key. -.sh 3 "Rebuilding the alias database" -.pp -The DB or DBM version of the database -may be rebuilt explicitly by executing the command -.(b -newaliases -.)b -This is equivalent to giving -.i sendmail -the -.b \-bi -flag: -.(b -/usr/\*(SD/sendmail \-bi -.)b -.pp -If the -.b RebuildAliases -(old -.b D ) -option is specified in the configuration, -.i sendmail -will rebuild the alias database automatically -if possible -when it is out of date. -Auto-rebuild can be dangerous -on heavily loaded machines -with large alias files; -if it might take more than the rebuild timeout -(option -.b AliasWait , -old -.b a , -which is normally five minutes) -to rebuild the database, -there is a chance that several processes will start the rebuild process -simultaneously. -.pp -If you have multiple aliases databases specified, -the -.b \-bi -flag rebuilds all the database types it understands -(for example, it can rebuild NDBM databases but not NIS databases). -.sh 3 "Potential problems" -.pp -There are a number of problems that can occur -with the alias database. -They all result from a -.i sendmail -process accessing the DBM version -while it is only partially built. -This can happen under two circumstances: -One process accesses the database -while another process is rebuilding it, -or the process rebuilding the database dies -(due to being killed or a system crash) -before completing the rebuild. -.pp -Sendmail has three techniques to try to relieve these problems. -First, it ignores interrupts while rebuilding the database; -this avoids the problem of someone aborting the process -leaving a partially rebuilt database. -Second, -it locks the database source file during the rebuild \(em -but that may not work over NFS or if the file is unwritable. -Third, -at the end of the rebuild -it adds an alias of the form -.(b -@: @ -.)b -(which is not normally legal). -Before -.i sendmail -will access the database, -it checks to insure that this entry exists\**. -.(f -\**The -.b AliasWait -option is required in the configuration -for this action to occur. -This should normally be specified. -.)f -.sh 3 "List owners" -.pp -If an error occurs on sending to a certain address, -say -.q \fIx\fP , -.i sendmail -will look for an alias -of the form -.q owner-\fIx\fP -to receive the errors. -This is typically useful -for a mailing list -where the submitter of the list -has no control over the maintenance of the list itself; -in this case the list maintainer would be the owner of the list. -For example: -.(b -unix-wizards: eric@ucbarpa, wnj@monet, nosuchuser, - sam@matisse -owner-unix-wizards: unix-wizards-request -unix-wizards-request: eric@ucbarpa -.)b -would cause -.q eric@ucbarpa -to get the error that will occur -when someone sends to -unix-wizards -due to the inclusion of -.q nosuchuser -on the list. -.pp -List owners also cause the envelope sender address to be modified. -The contents of the owner alias are used if they point to a single user, -otherwise the name of the alias itself is used. -For this reason, and to obey Internet conventions, -the -.q owner- -address normally points at the -.q -request -address; this causes messages to go out with the typical Internet convention -of using ``\c -.i list -request'' -as the return address. -.sh 2 "User Information Database" -.pp -If you have a version of -.i sendmail -with the user information database -compiled in, -and you have specified one or more databases using the -.b U -option, -the databases will be searched for a -.i user :maildrop -entry. -If found, the mail will be sent to the specified address. -.sh 2 "Per-User Forwarding (.forward Files)" -.pp -As an alternative to the alias database, -any user may put a file with the name -.q .forward -in his or her home directory. -If this file exists, -.i sendmail -redirects mail for that user -to the list of addresses listed in the .forward file. -For example, if the home directory for user -.q mckusick -has a .forward file with contents: -.(b -mckusick@ernie -kirk@calder -.)b -then any mail arriving for -.q mckusick -will be redirected to the specified accounts. -.pp -Actually, the configuration file defines a sequence of filenames to check. -By default, this is the user's .forward file, -but can be defined to be more generally using the -.b J -option. -If you change this, -you will have to inform your user base of the change; -\&.forward is pretty well incorporated into the collective subconscious. -.sh 2 "Special Header Lines" -.pp -Several header lines have special interpretations -defined by the configuration file. -Others have interpretations built into -.i sendmail -that cannot be changed without changing the code. -These builtins are described here. -.sh 3 "Errors-To:" -.pp -If errors occur anywhere during processing, -this header will cause error messages to go to -the listed addresses. -This is intended for mailing lists. -.pp -The Errors-To: header was created in the bad old days -when UUCP didn't understand the distinction between an envelope and a header; -this was a hack to provide what should now be passed -as the envelope sender address. -It should go away. -It is only used if the -.b UseErrorsTo -option is set. -.pp -The Errors-To: header is official deprecated -and will go away in a future release. -.sh 3 "Apparently-To:" -.pp -RFC 822 requires at least one recipient field -(To:, Cc:, or Bcc: line) -in every message. -If a message comes in with no recipients listed in the message -then -.i sendmail -will adjust the header based on the -.q NoRecipientAction -option. -One of the possible actions is to add an -.q "Apparently-To:" -header line for any recipients it is aware of. -This is not put in as a standard recipient line -to warn any recipients that the list is not complete. -.pp -The Apparently-To: header is non-standard -and is deprecated. -.sh 3 "Precedence" -.pp -The Precedence: header can be used as a crude control of message priority. -It tweaks the sort order in the queue -and can be configured to change the message timeout values. -.sh 2 "IDENT Protocol Support" -.pp -.i Sendmail -supports the IDENT protocol as defined in RFC 1413. -Although this enhances identification -of the author of an email message -by doing a ``call back'' to the originating system to include -the owner of a particular TCP connection -in the audit trail -it is in no sense perfect; -a determined forger can easily spoof the IDENT protocol. -The following description is excerpted from RFC 1413: -.ba +5 -.lp -6. Security Considerations -.lp -The information returned by this protocol is at most as trustworthy -as the host providing it OR the organization operating the host. For -example, a PC in an open lab has few if any controls on it to prevent -a user from having this protocol return any identifier the user -wants. Likewise, if the host has been compromised the information -returned may be completely erroneous and misleading. -.lp -The Identification Protocol is not intended as an authorization or -access control protocol. At best, it provides some additional -auditing information with respect to TCP connections. At worst, it -can provide misleading, incorrect, or maliciously incorrect -information. -.lp -The use of the information returned by this protocol for other than -auditing is strongly discouraged. Specifically, using Identification -Protocol information to make access control decisions - either as the -primary method (i.e., no other checks) or as an adjunct to other -methods may result in a weakening of normal host security. -.lp -An Identification server may reveal information about users, -entities, objects or processes which might normally be considered -private. An Identification server provides service which is a rough -analog of the CallerID services provided by some phone companies and -many of the same privacy considerations and arguments that apply to -the CallerID service apply to Identification. If you wouldn't run a -"finger" server due to privacy considerations you may not want to run -this protocol. -.ba -.lp -In some cases your system may not work properly with IDENT support -due to a bug in the TCP/IP implementation. -The symptoms will be that for some hosts -the SMTP connection will be closed -almost immediately. -If this is true or if you do not want to use IDENT, -you should set the IDENT timeout to zero; -this will disable the IDENT protocol. -.sh 1 "ARGUMENTS" -.pp -The complete list of arguments to -.i sendmail -is described in detail in Appendix A. -Some important arguments are described here. -.sh 2 "Queue Interval" -.pp -The amount of time between forking a process -to run through the queue -is defined by the -.b \-q -flag. -If you run with delivery mode set to -.b i -or -.b b -this can be relatively large, -since it will only be relevant -when a host that was down comes back up. -If you run in -.b q -mode -it should be relatively short, -since it defines the maximum amount of time that a message -may sit in the queue. -(See also the MinQueueAge option.) -.pp -RFC 1123 section 5.3.1.1 says that this value should be at least 30 minutes -(although that probably doesn't make sense if you use ``queue-only'' mode). -.sh 2 "Daemon Mode" -.pp -If you allow incoming mail over an IPC connection, -you should have a daemon running. -This should be set by your -.i /etc/rc -file using the -.b \-bd -flag. -The -.b \-bd -flag and the -.b \-q -flag may be combined in one call: -.(b -/usr/\*(SD/sendmail \-bd \-q30m -.)b -.pp -An alternative approach is to invoke sendmail from -.i inetd (8) -(use the -.b \-bs -flag to ask sendmail to speak SMTP on its standard input and output). -This works and allows you to wrap -.i sendmail -in a TCP wrapper program, -but may be a bit slower since the configuration file -has to be re-read on every message that comes in. -If you do this, you still need to have a -.i sendmail -running to flush the queue: -.(b -/usr/\*(SD/sendmail \-q30m -.)b -.sh 2 "Forcing the Queue" -.pp -In some cases you may find that the queue has gotten clogged for some reason. -You can force a queue run -using the -.b \-q -flag (with no value). -It is entertaining to use the -.b \-v -flag (verbose) -when this is done to watch what happens: -.(b -/usr/\*(SD/sendmail \-q \-v -.)b -.pp -You can also limit the jobs to those with a particular queue identifier, -sender, or recipient -using one of the queue modifiers. -For example, -.q \-qRberkeley -restricts the queue run to jobs that have the string -.q berkeley -somewhere in one of the recipient addresses. -Similarly, -.q \-qSstring -limits the run to particular senders and -.q \-qIstring -limits it to particular queue identifiers. -.sh 2 "Debugging" -.pp -There are a fairly large number of debug flags -built into -.i sendmail . -Each debug flag has a number and a level, -where higher levels means to print out more information. -The convention is that levels greater than nine are -.q absurd, -i.e., -they print out so much information that you wouldn't normally -want to see them except for debugging that particular piece of code. -Debug flags are set using the -.b \-d -option; -the syntax is: -.(b -.ta \w'debug-option 'u -debug-flag: \fB\-d\fP debug-list -debug-list: debug-option [ , debug-option ]* -debug-option: debug-range [ . debug-level ] -debug-range: integer | integer \- integer -debug-level: integer -.)b -where spaces are for reading ease only. -For example, -.(b -\-d12 Set flag 12 to level 1 -\-d12.3 Set flag 12 to level 3 -\-d3\-17 Set flags 3 through 17 to level 1 -\-d3\-17.4 Set flags 3 through 17 to level 4 -.)b -For a complete list of the available debug flags -you will have to look at the code -(they are too dynamic to keep this documentation up to date). -.sh 2 "Changing the Values of Options" -.pp -Options can be overridden using the -.b \-o -or -.b \-O -command line flags. -For example, -.(b -/usr/\*(SD/sendmail \-oT2m -.)b -sets the -.b T -(timeout) option to two minutes -for this run only; -the equivalent line using the long option name is -.(b -/usr/\*(SD/sendmail -OTimeout.queuereturn=2m -.)b -.pp -Some options have security implications. -Sendmail allows you to set these, -but relinquishes its setuid root permissions thereafter\**. -.(f -\**That is, it sets its effective uid to the real uid; -thus, if you are executing as root, -as from root's crontab file or during system startup -the root permissions will still be honored. -.)f -.sh 2 "Trying a Different Configuration File" -.pp -An alternative configuration file -can be specified using the -.b \-C -flag; for example, -.(b -/usr/\*(SD/sendmail \-Ctest.cf \-oQ/tmp/mqueue -.)b -uses the configuration file -.i test.cf -instead of the default -.i /etc/sendmail.cf. -If the -.b \-C -flag has no value -it defaults to -.i sendmail.cf -in the current directory. -.pp -.i Sendmail -gives up its setuid root permissions -when you use this flag, so it is common to use a publicly writable directory -(such as /tmp) -as the spool directory (QueueDirectory or Q option) while testing. -.sh 2 "Logging Traffic" -.pp -Many SMTP implementations do not fully implement the protocol. -For example, some personal computer based SMTPs -do not understand continuation lines in reply codes. -These can be very hard to trace. -If you suspect such a problem, you can set traffic logging using the -.b \-X -flag. -For example, -.(b -/usr/\*(SD/sendmail \-X /tmp/traffic \-bd -.)b -will log all traffic in the file -.i /tmp/traffic . -.pp -This logs a lot of data very quickly and should -.b NEVER -be used -during normal operations. -After starting up such a daemon, -force the errant implementation to send a message to your host. -All message traffic in and out of -.i sendmail , -including the incoming SMTP traffic, -will be logged in this file. -.sh 2 "Testing Configuration Files" -.pp -When you build a configuration table, -you can do a certain amount of testing -using the -.q "test mode" -of -.i sendmail . -For example, -you could invoke -.i sendmail -as: -.(b -sendmail \-bt \-Ctest.cf -.)b -which would read the configuration file -.q test.cf -and enter test mode. -In this mode, -you enter lines of the form: -.(b -rwset address -.)b -where -.i rwset -is the rewriting set you want to use -and -.i address -is an address to apply the set to. -Test mode shows you the steps it takes -as it proceeds, -finally showing you the address it ends up with. -You may use a comma separated list of rwsets -for sequential application of rules to an input. -For example: -.(b -3,1,21,4 monet:bollard -.)b -first applies ruleset three to the input -.q monet:bollard. -Ruleset one is then applied to the output of ruleset three, -followed similarly by rulesets twenty-one and four. -.pp -If you need more detail, -you can also use the -.q \-d21 -flag to turn on more debugging. -For example, -.(b -sendmail \-bt \-d21.99 -.)b -turns on an incredible amount of information; -a single word address -is probably going to print out several pages worth of information. -.pp -You should be warned that internally, -.i sendmail -applies ruleset 3 to all addresses. -In test mode -you will have to do that manually. -For example, older versions allowed you to use -.(b -0 bruce@broadcast.sony.com -.)b -This version requires that you use: -.(b -3,0 bruce@broadcast.sony.com -.)b -.pp -As of version 8.7, -some other syntaxes are available in test mode: -.bu -\&.D\|x\|value -defines macro -.i x -to have the indicated -.i value . -This is useful when debugging rules that use the -.b $& \c -.i x -syntax. -.bu -\&.C\|c\|value -adds the indicated -.i value -to class -.i c . -.bu -\&.S\|ruleset -dumps the contents of the indicated ruleset. -.bu -\-d\|debug-spec -is equivalent to the command-line flag. -.sh 2 "Persistent Host Status Information" -.pp -When -.b HostStatusDirectory -is enabled, -information about the status of hosts is maintained on disk -and can thus be shared between different instantiations of -.i sendmail . -The status of the last connection with each remote host -may be viewed with the command: -.(b -sendmail \-bh -.)b -This information may be flushed with the command: -.(b -sendmail \-bH -.)b -Flushing the information prevents new -.i sendmail -processes from loading it, -but does not prevent existing processes from using the status information -that they already have. -.sh 1 "TUNING" -.pp -There are a number of configuration parameters -you may want to change, -depending on the requirements of your site. -Most of these are set -using an option in the configuration file. -For example, -the line -.q "O Timeout.queuereturn=5d" -sets option -.q Timeout.queuereturn -to the value -.q 5d -(five days). -.pp -Most of these options have appropriate defaults for most sites. -However, -sites having very high mail loads may find they need to tune them -as appropriate for their mail load. -In particular, -sites experiencing a large number of small messages, -many of which are delivered to many recipients, -may find that they need to adjust the parameters -dealing with queue priorities. -.pp -All versions of -.i sendmail -prior to 8.7 -had single character option names. -As of 8.7, -options have long (multi-character names). -Although old short names are still accepted, -most new options do not have short equivalents. -.pp -This section only describes the options you are most likely -to want to tweak; -read section -.\"XREF -5 -for more details. -.sh 2 "Timeouts" -.pp -All time intervals are set -using a scaled syntax. -For example, -.q 10m -represents ten minutes, whereas -.q 2h30m -represents two and a half hours. -The full set of scales is: -.(b -.ta 4n -s seconds -m minutes -h hours -d days -w weeks -.)b -.sh 3 "Queue interval" -.pp -The argument to the -.b \-q -flag -specifies how often a sub-daemon will run the queue. -This is typically set to between fifteen minutes -and one hour. -RFC 1123 section 5.3.1.1 recommends that this be at least 30 minutes. -.sh 3 "Read timeouts" -.pp -Timeouts all have option names -.q Timeout.\fIsuboption\fP . -The recognized -.i suboption s, -their default values, and the minimum values -allowed by RFC 1123 section 5.3.2 are: -.nr ii 1i -.ip connect -The time to wait for an SMTP connection to open -(the -.i connect (2) -system call) -[0, unspecified]. -If zero, uses the kernel default. -In no case can this option extend the timeout -longer than the kernel provides, but it can shorten it. -This is to get around kernels that provide an absurdly long connection timeout -(90 minutes in one case). -.ip iconnect -The same as -.i connect, -except it applies only to the initial attempt to connect to a host -for a given message -[0, unspecified]. -The concept is that this should be very short (a few seconds); -hosts that are well connected and responsive will thus be serviced immediately. -Hosts that are slow will not hold up other deliveries in the initial -delivery attempt. -.ip initial -The wait for the initial 220 greeting message -[5m, 5m]. -.ip helo -The wait for a reply from a HELO or EHLO command -[5m, unspecified]. -This may require a host name lookup, so -five minutes is probably a reasonable minimum. -.ip mail\(dg -The wait for a reply from a MAIL command -[10m, 5m]. -.ip rcpt\(dg -The wait for a reply from a RCPT command -[1h, 5m]. -This should be long -because it could be pointing at a list -that takes a long time to expand -(see below). -.ip datainit\(dg -The wait for a reply from a DATA command -[5m, 2m]. -.ip datablock\(dg -The wait for reading a data block -(that is, the body of the message). -[1h, 3m]. -This should be long because it also applies to programs -piping input to -.i sendmail -which have no guarantee of promptness. -.ip datafinal\(dg -The wait for a reply from the dot terminating a message. -[1h, 10m]. -If this is shorter than the time actually needed -for the receiver to deliver the message, -duplicates will be generated. -This is discussed in RFC 1047. -.ip rset -The wait for a reply from a RSET command -[5m, unspecified]. -.ip quit -The wait for a reply from a QUIT command -[2m, unspecified]. -.ip misc -The wait for a reply from miscellaneous (but short) commands -such as NOOP (no-operation) and VERB (go into verbose mode). -[2m, unspecified]. -.ip command\(dg -In server SMTP, -the time to wait for another command. -[1h, 5m]. -.ip ident -The timeout waiting for a reply to an IDENT query -[30s\**, unspecified]. -.(f -\**On some systems the default is zero to turn the protocol off entirely. -.)f -.lp -For compatibility with old configuration files, -if no -.i suboption -is specified, -all the timeouts marked with \(dg are set to the indicated value. -.pp -Many of the RFC 1123 minimum values -may well be too short. -.i Sendmail -was designed to the RFC 822 protocols, -which did not specify read timeouts; -hence, versions of -.i sendmail -prior to version 8.1 did not guarantee to reply to messages promptly. -In particular, a -.q RCPT -command specifying a mailing list -will expand and verify the entire list; -a large list on a slow system -may easily take more than five minutes\**. -.(f -\**This verification includes looking up every address -with the name server; -this involves network delays, -and can in some cases can be considerable. -.)f -I recommend a one hour timeout \*- -since a communications failure during the RCPT phase is rare, -a long timeout is not onerous -and may ultimately help reduce network load -and duplicated messages. -.pp -For example, the lines: -.(b -O Timeout.command=25m -O Timeout.datablock=3h -.)b -sets the server SMTP command timeout to 25 minutes -and the input data block timeout to three hours. -.sh 3 "Message timeouts" -.pp -After sitting in the queue for a few days, -a message will time out. -This is to insure that at least the sender is aware -of the inability to send a message. -The timeout is typically set to five days. -It is sometimes considered convenient to also send a warning message -if the message is in the queue longer than a few hours -(assuming you normally have good connectivity; -if your messages normally took several hours to send -you wouldn't want to do this because it wouldn't be an unusual event). -These timeouts are set using the -.b Timeout.queuereturn -and -.b Timeout.queuewarn -options in the configuration file -(previously both were set using the -.b T -option). -.pp -Since these options are global, -and since you can not know -.i "a priori" -how long another host outside your domain will be down, -a five day timeout is recommended. -This allows a recipient to fix the problem even if it occurs -at the beginning of a long weekend. -RFC 1123 section 5.3.1.1 says that this parameter -should be ``at least 4\-5 days''. -.pp -The -.b Timeout.queuewarn -value can be piggybacked on the -.b T -option by indicating a time after which -a warning message should be sent; -the two timeouts are separated by a slash. -For example, the line -.(b -OT5d/4h -.)b -causes email to fail after five days, -but a warning message will be sent after four hours. -This should be large enough that the message will have been tried -several times. -.sh 2 "Forking During Queue Runs" -.pp -By setting the -.b ForkEachJob -(\c -.b Y ) -option, -.i sendmail -will fork before each individual message -while running the queue. -This will prevent -.i sendmail -from consuming large amounts of memory, -so it may be useful in memory-poor environments. -However, if the -.b ForkEachJob -option is not set, -.i sendmail -will keep track of hosts that are down during a queue run, -which can improve performance dramatically. -.pp -If the -.b ForkEachJob -option is set, -.i sendmail -can not use connection caching. -.sh 2 "Queue Priorities" -.pp -Every message is assigned a priority when it is first instantiated, -consisting of the message size (in bytes) -offset by the message class -(which is determined from the Precedence: header) -times the -.q "work class factor" -and the number of recipients times the -.q "work recipient factor." -The priority is used to order the queue. -Higher numbers for the priority mean that the message will be processed later -when running the queue. -.pp -The message size is included so that large messages are penalized -relative to small messages. -The message class allows users to send -.q "high priority" -messages by including a -.q Precedence: -field in their message; -the value of this field is looked up in the -.b P -lines of the configuration file. -Since the number of recipients affects the amount of load a message presents -to the system, -this is also included into the priority. -.pp -The recipient and class factors -can be set in the configuration file using the -.b RecipientFactor -(\c -.b y ) -and -.b ClassFactor -(\c -.b z ) -options respectively. -They default to 30000 (for the recipient factor) -and 1800 -(for the class factor). -The initial priority is: -.EQ -pri = msgsize - (class times bold ClassFactor) + (nrcpt times bold RecipientFactor) -.EN -(Remember, higher values for this parameter actually mean -that the job will be treated with lower priority.) -.pp -The priority of a job can also be adjusted each time it is processed -(that is, each time an attempt is made to deliver it) -using the -.q "work time factor," -set by the -.b RetryFactor -(\c -.b Z ) -option. -This is added to the priority, -so it normally decreases the precedence of the job, -on the grounds that jobs that have failed many times -will tend to fail again in the future. -The -.b RetryFactor -option defaults to 90000. -.sh 2 "Load Limiting" -.pp -.i Sendmail -can be asked to queue (but not deliver) -mail if the system load average gets too high -using the -.b QueueLA -(\c -.b x ) -option. -When the load average exceeds the value of the -.b QueueLA -option, -the delivery mode is set to -.b q -(queue only) -if the -.b QueueFactor -(\c -.b q ) -option divided by the difference in the current load average and the -.b QueueLA -option -plus one -exceeds the priority of the message \(em -that is, the message is queued iff: -.EQ -pri > { bold QueueFactor } over { LA - { bold QueueLA } + 1 } -.EN -The -.b QueueFactor -option defaults to 600000, -so each point of load average is worth 600000 -priority points -(as described above). -.pp -For drastic cases, -the -.b RefuseLA -(\c -.b X ) -option defines a load average at which -.i sendmail -will refuse -to accept network connections. -Locally generated mail -(including incoming UUCP mail) -is still accepted. -.sh 2 "Delivery Mode" -.pp -There are a number of delivery modes that -.i sendmail -can operate in, -set by the -.b DeliveryMode -(\c -.b d ) -configuration option. -These modes -specify how quickly mail will be delivered. -Legal modes are: -.(b -.ta 4n -i deliver interactively (synchronously) -b deliver in background (asynchronously) -q queue only (don't deliver) -d defer delvery attempts (don't deliver) -.)b -There are tradeoffs. -Mode -.q i -gives the sender the quickest feedback, -but may slow down some mailers and -is hardly ever necessary. -Mode -.q b -delivers promptly but -can cause large numbers of processes -if you have a mailer that takes a long time to deliver a message. -Mode -.q q -minimizes the load on your machine, -but means that delivery may be delayed for up to the queue interval. -Mode -.q d -is identical to mode -.q q -except that it also prevents all the early map lookups from working; -it is intended for ``dial on demand'' sites where DNS lookups -might cost real money. -Some simple error messages -(e.g., host unknown during the SMTP protocol) -will be delayed using this mode. -Mode -.q b -is the usual default. -.pp -If you run in mode -.q q -(queue only), -.q d -(defer), -or -.q b -(deliver in background) -.i sendmail -will not expand aliases and follow .forward files -upon initial receipt of the mail. -This speeds up the response to RCPT commands. -Mode -.q i -cannot be used by the SMTP server. -.sh 2 "Log Level" -.pp -The level of logging can be set for -.i sendmail . -The default using a standard configuration table is level 9. -The levels are as follows: -.nr ii 0.5i -.ip 0 -No logging. -.ip 1 -Serious system failures and potential security problems. -.ip 2 -Lost communications (network problems) and protocol failures. -.ip 3 -Other serious failures. -.ip 4 -Minor failures. -.ip 5 -Message collection statistics. -.ip 6 -Creation of error messages, -VRFY and EXPN commands. -.ip 7 -Delivery failures (host or user unknown, etc.). -.ip 8 -Successful deliveries and alias database rebuilds. -.ip 9 -Messages being deferred -(due to a host being down, etc.). -.ip 10 -Database expansion (alias, forward, and userdb lookups). -.ip 12 -Log all incoming and outgoing SMTP commands. -.ip 20 -Logs attempts to run locked queue files. -These are not errors, -but can be useful to note if your queue appears to be clogged. -.ip 30 -Lost locks (only if using lockf instead of flock). -.lp -Additionally, -values above 64 are reserved for extremely verbose debugging output. -No normal site would ever set these. -.sh 2 "File Modes" -.pp -The modes used for files depend on what functionality you want -and the level of security you require. -.sh 3 "To suid or not to suid?" -.pp -.i Sendmail -can safely be made -setuid to root. -At the point where it is about to -.i exec \|(2) -a mailer, -it checks to see if the userid is zero; -if so, -it resets the userid and groupid to a default -(set by the -.b u -and -.b g -options). -(This can be overridden -by setting the -.b S -flag to the mailer -for mailers that are trusted -and must be called as root.) -However, -this will cause mail processing -to be accounted -(using -.i sa \|(8)) -to root -rather than to the user sending the mail. -.pp -If you don't make -.i sendmail -setuid to root, it will still run but you lose a lot of functionality -and a lot of privacy, since you'll have to make the queue directory -world readable. -You could also make -.i sendmail -setuid to some pseudo-user -(e.g., create a user called -.q sendmail -and make -.i sendmail -setuid to that) -which will fix the privacy problems -but not the functionality issues. -Also, this isn't a guarantee of security: -for example, -root occasionally sends mail, -and the daemon often runs as root. -.sh 3 "Should my alias database be writable?" -.pp -At Berkeley -we have the alias database -(/etc/aliases*) -mode 644. -While this is not as flexible as if the database -were more 666, it avoids potential security problems -with a globally writable database. -.pp -The database that -.i sendmail -actually used -is represented by the two files -.i aliases.dir -and -.i aliases.pag -(both in /etc) -(or -.i aliases.db -if you are running with the new Berkeley database primitives). -The mode on these files should match the mode -on /etc/aliases. -If -.i aliases -is writable -and the -DBM -files -(\c -.i aliases.dir -and -.i aliases.pag ) -are not, -users will be unable to reflect their desired changes -through to the actual database. -However, -if -.i aliases -is read-only -and the DBM files are writable, -a slightly sophisticated user -can arrange to steal mail anyway. -.pp -If your DBM files are not writable by the world -or you do not have auto-rebuild enabled -(with the -.b AutoRebuildAliases -option), -then you must be careful to reconstruct the alias database -each time you change the text version: -.(b -newaliases -.)b -If this step is ignored or forgotten -any intended changes will also be ignored or forgotten. -.sh 2 "Connection Caching" -.pp -When processing the queue, -.i sendmail -will try to keep the last few open connections open -to avoid startup and shutdown costs. -This only applies to IPC connections. -.pp -When trying to open a connection -the cache is first searched. -If an open connection is found, it is probed to see if it is still active -by sending a -.sm RSET -command. -It is not an error if this fails; -instead, the connection is closed and reopened. -.pp -Two parameters control the connection cache. -The -.b ConnectionCacheSize -(\c -.b k ) -option defines the number of simultaneous open connections -that will be permitted. -If it is set to zero, -connections will be closed as quickly as possible. -The default is one. -This should be set as appropriate for your system size; -it will limit the amount of system resources that -.i sendmail -will use during queue runs. -Never set this higher than 4. -.pp -The -.b ConnectionCacheTimeout -(\c -.b K ) -option specifies the maximum time that any cached connection -will be permitted to idle. -When the idle time exceeds this value -the connection is closed. -This number should be small -(under ten minutes) -to prevent you from grabbing too many resources -from other hosts. -The default is five minutes. -.sh 2 "Name Server Access" -.pp -Control of host address lookups is set by the -.b hosts -service entry in your service switch file. -If you are on a system that has built-in service switch support -(e.g., Ultrix, Solaris, or DEC OSF/1) -then your system is probably configured properly already. -Otherwise, -.i sendmail -will consult the file -.b /etc/service.switch , -which should be created. -.i Sendmail -only uses two entries: -.b hosts -and -.b aliases . -.pp -However, some systems (such as SunOS) -will do DNS lookups -regardless of the setting of the service switch entry. -In particular, the system routine -.i gethostbyname (3) -is used to look up host names, -and many vendor versions try some combination of DNS, NIS, -and file lookup in /etc/hosts -without consulting a service switch. -.i Sendmail -makes no attempt to work around this problem, -and the DNS lookup will be done anyway. -If you do not have a nameserver configured at all, -such as at a UUCP-only site, -.i sendmail -will get a -.q "connection refused" -message when it tries to connect to the name server. -If the -.b hosts -switch entry has the service -.q dns -listed somewhere in the list, -.i sendmail -will interpret this to mean a temporary failure -and will queue the mail for later processing; -otherwise, it ignores the name server data. -.pp -The same technique is used to decide whether to do MX lookups. -If you want MX support, you -.i must -have -.q dns -listed as a service in the -.b hosts -switch entry. -.pp -The -.b ResolverOptions -(\c -.b I ) -option allows you to tweak name server options. -The command line takes a series of flags as documented in -.i resolver (3) -(with the leading -.q RES_ -deleted). -Each can be preceded by an optional `+' or `\(mi'. -For example, the line -.(b -O ResolverOptions=+AAONLY \(miDNSRCH -.)b -turns on the AAONLY (accept authoritative answers only) -and turns off the DNSRCH (search the domain path) options. -Most resolver libraries default DNSRCH, DEFNAMES, and RECURSE -flags on and all others off. -You can also include -.q HasWildcardMX -to specify that there is a wildcard MX record matching your domain; -this turns off MX matching when canonifying names, -which can lead to inappropriate canonifications. -.pp -Version level 1 configurations -turn DNSRCH and DEFNAMES off when doing delivery lookups, -but leave them on everywhere else. -Version 8 of -.i sendmail -ignores them when doing canonification lookups -(that is, when using $[ ... $]), -and always does the search. -If you don't want to do automatic name extension, -don't call $[ ... $]. -.pp -The search rules for $[ ... $] are somewhat different than usual. -If the name being looked up -has at least one dot, it always tries the unmodified name first. -If that fails, it tries the reduced search path, -and lastly tries the unmodified name -(but only for names without a dot, -since names with a dot have already been tried). -This allows names such as -``utc.CS'' -to match the site in Czechoslovakia -rather than the site in your local Computer Science department. -It also prefers A and CNAME records over MX records \*- -that is, if it finds an MX record it makes note of it, -but keeps looking. -This way, if you have a wildcard MX record matching your domain, -it will not assume that all names match. -.pp -To completely turn off all name server access -on systems without service switch support -(such as SunOS) -you will have to recompile with -\-DNAMED_BIND=0 -and remove \-lresolv from the list of libraries to be searched -when linking. -.sh 2 "Moving the Per-User Forward Files" -.pp -Some sites mount each user's home directory -from a local disk on their workstation, -so that local access is fast. -However, the result is that .forward file lookups are slow. -In some cases, -mail can even be delivered on machines inappropriately -because of a file server being down. -The performance can be especially bad if you run the automounter. -.pp -The -.b ForwardPath -(\c -.b J ) -option allows you to set a path of forward files. -For example, the config file line -.(b -O ForwardPath=/var/forward/$u:$z/.forward.$w -.)b -would first look for a file with the same name as the user's login -in /var/forward; -if that is not found (or is inaccessible) -the file -``.forward.\c -.i machinename '' -in the user's home directory is searched. -A truly perverse site could also search by sender -by using $r, $s, or $f. -.pp -If you create a directory such as /var/forward, -it should be mode 1777 -(that is, the sticky bit should be set). -Users should create the files mode 644. -.sh 2 "Free Space" -.pp -On systems that have one of the system calls in the -.i statfs (2) -family -(including -.i statvfs -and -.i ustat ), -you can specify a minimum number of free blocks on the queue filesystem -using the -.b MinFreeBlocks -(\c -.b b ) -option. -If there are fewer than the indicated number of blocks free -on the filesystem on which the queue is mounted -the SMTP server will reject mail -with the -452 error code. -This invites the SMTP client to try again later. -.pp -Beware of setting this option too high; -it can cause rejection of email -when that mail would be processed without difficulty. -.sh 2 "Maximum Message Size" -.pp -To avoid overflowing your system with a large message, -the -.b MaxMessageSize -option can be set to set an absolute limit -on the size of any one message. -This will be advertised in the ESMTP dialogue -and checked during message collection. -.sh 2 "Privacy Flags" -.pp -The -.b PrivacyOptions -(\c -.b p ) -option allows you to set certain -``privacy'' -flags. -Actually, many of them don't give you any extra privacy, -rather just insisting that client SMTP servers -use the HELO command -before using certain commands -or adding extra headers to indicate possible spoof attempts. -.pp -The option takes a series of flag names; -the final privacy is the inclusive or of those flags. -For example: -.(b -O PrivacyOptions=needmailhelo, noexpn -.)b -insists that the HELO or EHLO command be used before a MAIL command is accepted -and disables the EXPN command. -.pp -The flags are detailed in section -.\"XREF -5.6. -.sh 2 "Send to Me Too" -.pp -Normally, -.i sendmail -deletes the (envelope) sender from any list expansions. -For example, if -.q matt -sends to a list that contains -.q matt -as one of the members he won't get a copy of the message. -If the -.b \-m -(me too) -command line flag, or if the -.b MeToo -(\c -.b m ) -option is set in the configuration file, -this behaviour is suppressed. -Some sites like to run the -.sm SMTP -daemon with -.b \-m . -.sh 1 "THE WHOLE SCOOP ON THE CONFIGURATION FILE" -.pp -This section describes the configuration file -in detail. -.pp -There is one point that should be made clear immediately: -the syntax of the configuration file -is designed to be reasonably easy to parse, -since this is done every time -.i sendmail -starts up, -rather than easy for a human to read or write. -On the -.q "future project" -list is a -configuration-file compiler. -.pp -The configuration file is organized as a series of lines, -each of which begins with a single character -defining the semantics for the rest of the line. -Lines beginning with a space or a tab -are continuation lines -(although the semantics are not well defined in many places). -Blank lines and lines beginning with a sharp symbol -(`#') -are comments. -.sh 2 "R and S \*- Rewriting Rules" -.pp -The core of address parsing -are the rewriting rules. -These are an ordered production system. -.i Sendmail -scans through the set of rewriting rules -looking for a match on the left hand side -(LHS) -of the rule. -When a rule matches, -the address is replaced by the right hand side -(RHS) -of the rule. -.pp -There are several sets of rewriting rules. -Some of the rewriting sets are used internally -and must have specific semantics. -Other rewriting sets -do not have specifically assigned semantics, -and may be referenced by the mailer definitions -or by other rewriting sets. -.pp -The syntax of these two commands are: -.(b F -.b S \c -.i n -.)b -Sets the current ruleset being collected to -.i n . -If you begin a ruleset more than once -it appends to the old definition. -.(b F -.b R \c -.i lhs -.i rhs -.i comments -.)b -The -fields must be separated -by at least one tab character; -there may be embedded spaces -in the fields. -The -.i lhs -is a pattern that is applied to the input. -If it matches, -the input is rewritten to the -.i rhs . -The -.i comments -are ignored. -.pp -Macro expansions of the form -.b $ \c -.i x -are performed when the configuration file is read. -Expansions of the form -.b $& \c -.i x -are performed at run time using a somewhat less general algorithm. -This for is intended only for referencing internally defined macros -such as -.b $h -that are changed at runtime. -.sh 3 "The left hand side" -.pp -The left hand side of rewriting rules contains a pattern. -Normal words are simply matched directly. -Metasyntax is introduced using a dollar sign. -The metasymbols are: -.(b -.ta \w'\fB$=\fP\fIx\fP 'u -\fB$*\fP Match zero or more tokens -\fB$+\fP Match one or more tokens -\fB$\-\fP Match exactly one token -\fB$=\fP\fIx\fP Match any phrase in class \fIx\fP -\fB$~\fP\fIx\fP Match any word not in class \fIx\fP -.)b -If any of these match, -they are assigned to the symbol -.b $ \c -.i n -for replacement on the right hand side, -where -.i n -is the index in the LHS. -For example, -if the LHS: -.(b -$\-:$+ -.)b -is applied to the input: -.(b -UCBARPA:eric -.)b -the rule will match, and the values passed to the RHS will be: -.(b -.ta 4n -$1 UCBARPA -$2 eric -.)b -.pp -Additionally, the LHS can include -.b $@ -to match zero tokens. -This is -.i not -bound to a -.b $ \c -.i n -on the RHS, and is normally only used when it stands alone -in order to match the null input. -.sh 3 "The right hand side" -.pp -When the left hand side of a rewriting rule matches, -the input is deleted and replaced by the right hand side. -Tokens are copied directly from the RHS -unless they begin with a dollar sign. -Metasymbols are: -.(b -.ta \w'$#mailer\0\0\0'u -\fB$\fP\fIn\fP Substitute indefinite token \fIn\fP from LHS -\fB$[\fP\fIname\fP\fB$]\fP Canonicalize \fIname\fP -\fB$(\fP\fImap key\fP \fB$@\fP\fIarguments\fP \fB$:\fP\fIdefault\fP \fB$)\fP - Generalized keyed mapping function -\fB$>\fP\fIn\fP \*(lqCall\*(rq ruleset \fIn\fP -\fB$#\fP\fImailer\fP Resolve to \fImailer\fP -\fB$@\fP\fIhost\fP Specify \fIhost\fP -\fB$:\fP\fIuser\fP Specify \fIuser\fP -.)b -.pp -The -.b $ \c -.i n -syntax substitutes the corresponding value from a -.b $+ , -.b $\- , -.b $* , -.b $= , -or -.b $~ -match on the LHS. -It may be used anywhere. -.pp -A host name enclosed between -.b $[ -and -.b $] -is looked up in the host database(s) -and replaced by the canonical name\**. -.(f -\**This is actually -completely equivalent -to $(host \fIhostname\fP$). -In particular, a -.b $: -default can be used. -.)f -For example, -.q $[ftp$] -might become -.q ftp.CS.Berkeley.EDU -and -.q $[[128.32.130.2]$] -would become -.q vangogh.CS.Berkeley.EDU. -.i Sendmail -recognizes it's numeric IP address -without calling the name server -and replaces it with it's canonical name. -.pp -The -.b $( -\&... -.b $) -syntax is a more general form of lookup; -it uses a named map instead of an implicit map. -If no lookup is found, the indicated -.i default -is inserted; -if no default is specified and no lookup matches, -the value is left unchanged. -The -.i arguments -are passed to the map for possible use. -.pp -The -.b $> \c -.i n -syntax -causes the remainder of the line to be substituted as usual -and then passed as the argument to ruleset -.i n . -The final value of ruleset -.i n -then becomes -the substitution for this rule. -The -.b $> -syntax can only be used at the beginning of the right hand side; -it can be only be preceded by -.b $@ -or -.b $: . -.pp -The -.b $# -syntax should -.i only -be used in ruleset zero -or a subroutine of ruleset zero. -It causes evaluation of the ruleset to terminate immediately, -and signals to -.i sendmail -that the address has completely resolved. -The complete syntax is: -.(b -\fB$#\fP\fImailer\fP \fB$@\fP\fIhost\fP \fB$:\fP\fIuser\fP -.)b -This specifies the -{mailer, host, user} -3-tuple necessary to direct the mailer. -If the mailer is local -the host part may be omitted\**. -.(f -\**You may want to use it for special -.q "per user" -extensions. -For example, in the address -.q jgm+foo@CMU.EDU ; -the -.q +foo -part is not part of the user name, -and is passed to the local mailer for local use. -.)f -The -.i mailer -must be a single word, -but the -.i host -and -.i user -may be multi-part. -If the -.i mailer -is the builtin IPC mailer, -the -.i host -may be a colon-separated list of hosts -that are searched in order for the first working address -(exactly like MX records). -The -.i user -is later rewritten by the mailer-specific envelope rewriting set -and assigned to the -.b $u -macro. -As a special case, if the mailer specified has the -.b F=@ -flag specified -and the first character of the -.b $: -value is -.q @ , -the -.q @ -is stripped off, and a flag is set in the address descriptor -that causes sendmail to not do ruleset 5 processing. -.pp -Normally, a rule that matches is retried, -that is, -the rule loops until it fails. -A RHS may also be preceded by a -.b $@ -or a -.b $: -to change this behavior. -A -.b $@ -prefix causes the ruleset to return with the remainder of the RHS -as the value. -A -.b $: -prefix causes the rule to terminate immediately, -but the ruleset to continue; -this can be used to avoid continued application of a rule. -The prefix is stripped before continuing. -.pp -The -.b $@ -and -.b $: -prefixes may precede a -.b $> -spec; -for example: -.(b -.ta 8n -R$+ $: $>7 $1 -.)b -matches anything, -passes that to ruleset seven, -and continues;

-using the null return address -as required by RFC 1123. -However, some mailers don't accept a null return address. -If necessary, -you can set the -.b g -flag to prevent -.i sendmail -from obeying the standards; -error messages will be sent as from the MAILER-DAEMON -(actually, the value of the -.b $n -macro). -.ip h -Upper case should be preserved in host names -for this mailer. -.ip i -Do User Database rewriting on envelope sender address. -.ip I -This mailer will be speaking SMTP -to another -.i sendmail -\*- -as such it can use special protocol features. -This option is not required -(i.e., -if this option is omitted the transmission will still operate successfully, -although perhaps not as efficiently as possible). -.ip j -Do User Database rewriting on recipients as well as senders. -.ip k -Normally when -.i sendmail -connects to a host via SMTP, -it checks to make sure that this isn't accidently the same host name -as might happen if -.i sendmail -is misconfigured or if a long-haul network interface is set in loopback mode. -This flag disables the loopback check. -It should only be used under very unusual circumstances. -.ip K -Currently unimplemented. -Reserved for chunking. -.ip l -This mailer is local -(i.e., -final delivery will be performed). -.ip L -Limit the line lengths as specified in RFC821. -This deprecated option should be replaced by the -.b L= -mail declaration. -For historic reasons, the -.b L -flag also sets the -.b 7 -flag. -.ip m -This mailer can send to multiple users -on the same host -in one transaction. -When a -.b $u -macro occurs in the -.i argv -part of the mailer definition, -that field will be repeated as necessary -for all qualifying users. -.ip M\(dg -This mailer wants a -.q Message-Id: -header line. -.ip n -Do not insert a

-(actually, the user specified in the -.b u -option) -when delivering network mail. -The normal behaviour is required by most local mailers, -which will not allow the envelope sender address -to be set unless the mailer is running as daemon. -This flag is ignored if the -.b S -flag is set. -.ip p -Use the route-addr style reverse-path in the SMTP -.q "MAIL FROM:" -command -rather than just the return address; -although this is required in RFC821 section 3.1, -many hosts do not process reverse-paths properly. -Reverse-paths are officially discouraged by RFC 1123. -.ip P\(dg -This mailer wants a -.q Return-Path: -line. -.ip q -When an address that resolves to this mailer is verified -(SMTP VRFY command), -generate 250 responses instead of 252 responses. -This will imply that the address is local. -.ip r -Same as -.b f , -but sends a -.b \-r -flag. -.ip R -Open SMTP connections from a -.q secure -port. -Secure ports aren't -(secure, that is) -except on UNIX machines, -so it is unclear that this adds anything. -.ip s -Strip quote characters (" and \e) off of the address -before calling the mailer. -.ip S -Don't reset the userid -before calling the mailer. -This would be used in a secure environment -where -.i sendmail -ran as root. -This could be used to avoid forged addresses. -If the -.b U= -field is also specified, -this flag causes the user id to always be set to that user and group -(instead of leaving it as root). -.ip u -Upper case should be preserved in user names -for this mailer. -.ip U -This mailer wants UUCP-style -.q From -lines with the ugly -.q "remote from " -on the end. -.ip w -The user must have a valid account on this machine, -i.e., -getpwnam -must succeed. -If not, -the mail is bounced. -This is required to get -.q \&.forward -capability. -.ip x\(dg -This mailer wants a -.q Full-Name: -header line. -.ip X -This mailer want to use the hidden dot algorithm -as specified in RFC821; -basically, -any line beginning with a dot -will have an extra

via SMTP. -.ip 3 -Extend the list of characters converted to =XX notation -when converting to Quoted-Printable -to include those that don't map cleanly between ASCII and EBCDIC. -Useful if you have IBM mainframes on site. -.ip 5 -If no aliases are found for this address, -pass the address through ruleset 5 for possible alternate resolution. -This is intended to forward the mail to an alternate delivery spot. -.ip 7 -Strip all output to seven bits. -This is the default if the -.b L -flag is set. -Note that clearing this option is not -sufficient to get full eight bit data passed through -.i sendmail . -If the -.b 7 -option is set, this is essentially always set, -since the eighth bit was stripped on input. -Note that this option will only impact messages -that didn't have 8\(->7 bit MIME conversions performed. -.ip 8 -If set, -it is acceptable to send eight bit data to this mailer; -the usual attempt to do 8\(->7 bit MIME conversions will be bypassed. -.ip 9 -If set, -do -.i limited -7\(->8 bit MIME conversions. -These conversions are limited to text/plain data. -.ip : -Check addresses to see if they begin -.q :include: ; -if they do, convert them to the -.q *include* -mailer.

. -.pp -The mailer with the special name -.q error -can be used to generate a user error. -The (optional) host field is an exit status to be returned, -and the user field is a message to be printed. -The exit status may be numeric or one of the values -USAGE, NOUSER, NOHOST, UNAVAILABLE, SOFTWARE, TEMPFAIL, PROTOCOL, or CONFIG -to return the corresponding EX_ exit code, -or an enhanced error code as described in RFC 1893, -.ul -Enhanced Mail System Status Codes. -For example, the entry: -.(b -$#error $@ NOHOST $: Host unknown in this domain -.)b -on the RHS of a rule -will cause the specified error to be generated -and the -.q "Host unknown" -exit status to be returned -if the LHS matches. -This mailer is only functional in rulesets 0, 5, -or one of the check_* rulesets. -.pp -The mailer named -.q local -.i must -be defined in every configuration file. -This is used to deliver local mail, -and is treated specially in several ways. -Additionally, three other mailers named -.q prog ,

by a slash; -if so, the first rewriting set is applied to envelope -addresses -and the second is applied to headers. -.pp -The Directory -is actually a colon-separated path of directories to try. -For example, the definition -.q D=$z:/ -first tries to execute in the recipient's home directory; -if that is not available, -it tries to execute in the root of the filesystem. -This is intended to be used only on the -.q prog -mailer, -since some shells (such as -.i csh ) -refuse to execute if they cannot read the home directory. -Since the queue directory is not normally readable by unprivileged users -.i csh -scripts as recipients can fail. -.pp -The Userid -specifies the default user and group id to run as, -overriding the -.b DefaultUser -option (q.v.). -If the -.b S -mailer flag is also specified, -this is the user and group to run as in all circumstances. -This may be given as -.i user:group -to set both the user and group id; -either may be an integer or a symbolic name to be looked up -in the -.i passwd -and -.i group -files respectively. -If only a symbolic user name is specified, -the group id in the -.i passwd -file for that user is used as the group id. -.pp -The Charset field -is used when converting a message to MIME; -this is the character set used in the -Content-Type: header. -If this is not set, the -.b DefaultCharset -option is used, -and if that is not set, the value -.q unknown-8bit -is used. -.b WARNING: -this field applies to the sender's mailer, -not the recipient's mailer. -For example, if the envelope sender address -lists an address on the local network -and the recipient is on an external network, -the character set will be set from the Charset= field -for the local network mailer, -not that of the external network mailer. -.pp -The Type= field -sets the type information -used in MIME error messages -as defined by -RFC 1894. -It is actually three values separated by slashes: -the MTA-type (that is, the description of how hosts are named), -the address type (the description of e-mail addresses), -and the diagnostic type (the description of error diagnostic codes). -Each of these must be a registered value -or begin with -.q X\- . -The default is -.q dns/rfc822/smtp . -.sh 2 "H \*- Define Header" -.pp -The format of the header lines that -.i sendmail -inserts into the message -are defined by the -.b H -line. -The syntax of this line is: -.(b F -.b H [\c -.b ? \c -.i mflags \c -.b ? ]\c -.i hname \c -.b : -.i htemplate -.)b -Continuation lines in this spec -are reflected directly into the outgoing message. -The -.i htemplate -is macro expanded before insertion into the message. -If the -.i mflags -(surrounded by question marks) -are specified, -at least one of the specified flags -must be stated in the mailer definition -for this header to be automatically output. -If one of these headers is in the input -it is reflected to the output -regardless of these flags. -.pp -Some headers have special semantics -that will be described later. -.sh 2 "O \*- Set Option" -.pp -There are a number of -global -options that -can be set from a configuration file. -Options are represented by full words; -some are also

that there -.i must -be a space between the letter `O' and the name of the option. -An older version is: -.(b F -.b O \c -.i o\|value -.)b -where the option -.i o -is a single character. -Depending on the option, -.i value -may be a string, an integer, -a boolean -(with legal values -.q t , -.q T , -.q f , -or -.q F ; -the default is TRUE), -or -a time interval. -.pp -The options supported (with

-.i timeout -(units default to minutes) -for an -.q @:@ -entry to exist in the alias database -before starting up. -If it does not appear in the -.i timeout -interval -rebuild the database -(if the -.b AutoRebuildAliases -option is also set) -or issue a warning. -.ip AllowBogusHELO -[no short name] -If set, allow HELO SMTP commands that don't include a host name. -Setting this violates RFC 1123 section 5.2.5, -but is necessary to interoperate with several SMTP clients. -If there is a value, it is still checked for legitimacy. -.ip AutoRebuildAliases -[D] -If set, -rebuild the alias database if necessary and possible. -If this option is not set, -.i sendmail -will never rebuild the alias database -unless explicitly requested -using -.b \-bi . -Not recommended \(em can cause thrashing. -.ip BlankSub=\fIc\fP -[B] -Set the blank substitution character to -.i c . -Unquoted spaces in addresses are replaced by this character. -Defaults to space (i.e., no change is made). -.ip CheckAliases -[n] -Validate the RHS of aliases when rebuilding the alias database. -.ip CheckpointInterval=\fIN\fP -[C] -Checkpoints the queue every -.i N -(default 10) -addresses sent. -If your

message class -(determined by the Precedence: field in the user header -and the -.b P -lines in the configuration file) -and subtracted from the priority. -Thus, messages with a higher Priority: will be favored. -Defaults to 1800. -.ip ColonOkInAddr -[no short name] -If set, colons are acceptable in e-mail addresses -(e.g., -.q host:user ). -If not set, colons indicate the beginning of a RFC 822 group construct -(\c -.q "groupname: member1, member2, ... memberN;" ). -Doubled colons are always acceptable -(\c -.q nodename::user ) -and proper route-addr nesting is understood -(\c -.q <@relay:user@host> ). -Furthermore, this option defaults on if the configuration version level -is less than 6 (for back compatibility). -However, it must be off for full compatibility with RFC 822. -.ip ConnectionCacheSize=\fIN\fP -[k] -The maximum number of open connections that will be cached at a time. -The default is one. -This delays closing the current connection until -either this invocation of -.i sendmail -needs to connect to another host -or it terminates. -Setting it to zero defaults to the old behavior, -that is, connections are closed immediately. -Since this consumes file descriptors, -the connection cache should be kept small: -4 is probably a practical maximum. -.ip ConnectionCacheTimeout=\fItimeout\fP -[K] -The maximum amount of time a cached connection will be permitted to idle -without activity. -If this time is exceeded, -the connection is immediately closed. -This value should be small (on the order of ten minutes). -Before -.i sendmail -uses a cached connection, -it always sends a RSET command -to check the connection; -if this fails, it reopens the connection. -This keeps your end from failing if the other end times out. -The point of this option is to be a good network neighbor -and avoid using up excessive resources -on the other end. -The default is five minutes. -.ip ConnectionRateThrottle=\fIN\fP -[no short name] -If set to a positive value, -allow no more than -.i N -incoming daemon connections in a one second period. -This is intended to flatten out peaks -and allow the load average checking to cut in. -Defaults to zero (no

receive buffer -.)b -The -.i Addr ess -mask may be a numeric address in dot notation -or a network name. -.ip DefaultCharSet=\fIcharset\fP -[no short name] -When a message that has 8-bit characters but is not in MIME format -is converted to MIME -(see the EightBitMode option) -a character set must be included in the Content-Type: header. -This character set is normally set from the Charset= field -of the mailer descriptor. -If that is not set, the value of this option is used. -If this option is not set, the value -.q unknown-8bit -is used. -.ip DefaultUser=\fIuser:group\fP -[u] -Set the default userid for mailers to -.i user:group . -If -.i group -is omitted and -.i user -is a user name -(as opposed to a numeric user id) -the default group listed in the /etc/passwd file for that user is used -as the default group. -Both -.i user -and -.i group -may be numeric. -Mailers without the -.i S -flag in the mailer definition -will run as this user. -Defaults to 1:1. -The value can also be

-.ta 4n -i Deliver interactively (synchronously) -b Deliver in background (asynchronously) -q Just queue the message (deliver during queue run) -d Defer delivery and all map lookups (deliver during queue run) -.)b -Defaults to ``b'' if no option is specified, -``i'' if it is specified but given no argument -(i.e., ``Od'' is equivalent to ``Odi''). -The -.b \-v -command line flag sets this to -.b i . -.ip DialDelay=\fIsleeptime\fP -[no short name] -Dial-on-demand network connections can see timeouts -if a connection is opened before the call is set up. -If this is set to an interval and a connection times out -on the first connection being attempted -.i sendmail -will sleep for this amount of time and try again. -This should give your system time to establish the connection -to your service provider. -Units default to seconds, so -.q DialDelay=5 -uses a five second delay. -Defaults to zero -(no retry). -.ip DontExpandCnames -[no short name] -The standards say that all host addresses used in a mail message -must be fully canonical. -For example, if your host is named -.q Cruft.Foo.ORG -and also has an alias of -.q FTP.Foo.ORG , -the former name must be used at all times. -This is enforced during host name canonification -($[ ... $] lookups). -If this option is set, the protocols are ignored and the -.q wrong -thing is done. -However, the IETF is moving toward changing this standard, -so the behaviour may become acceptable. -Please note that hosts downstream may still rewrite the address -to be the true canonical name however. -.ip DontInitGroups -[no short name] -If set, -.i sendmail -will avoid using the initgroups(3) call. -If you are running NIS, -this causes a sequential scan of the groups.byname map, -which can cause your NIS server to be badly overloaded in a large domain. -The cost of this is that the only group found for users -will be their primary group (the one in the password file), -which will make file access permissions somewhat more restrictive. -Has no effect on systems that don't have group lists. -.ip DontPruneRoutes -[R] -Normally, -.i sendmail -tries to eliminate any unnecessary explicit routes -when sending an error message -(as discussed in RFC 1123 \(sc 5.2.6). -For example, -when sending an error message to -.(b -<@known1,@known2,@known3:user@unknown> -.)b -.i sendmail -will strip off the -.q @known1,@known2 -in order to make the route as direct as possible. -However, if the -.b R -option is set, this will be disabled, -and the mail will be sent to the first address in the route, -even if later addresses are known. -This may be useful if you are caught behind a firewall. -.ip DoubleBounceAddress=\fIerror-address\fP -[no short name] -If an error occurs when sending an error message, -send the error report -(termed a -.q "double bounce" -because it is an error -.q bounce -that occurs when trying to send another error -.q bounce ) -to the indicated address. -If not set, defaults to -.q postmaster . -.ip EightBitMode=\fIaction\fP -[8] -Set handling of eight-bit data. -There are two kinds of eight-bit data: -that declared as such using the -.b BODY=8BITMIME -ESMTP declaration or the -.b \-B8BITMIME -command line flag, -and undeclared 8-bit data, that is, -input that just happens to be eight bits. -There are three basic operations that can happen: -undeclared 8-bit data can be automatically converted to 8BITMIME, -undeclared 8-bit data can be passed as-is without conversion to MIME -(``just send 8''), -and declared 8-bit data can be converted to 7-bits -for transmission to

-this gives the config file a way of finding out if anything matched. -(Actually, this just initializes the -.q host -map with the -.q \-a. -flag \*- you can reset it to anything you prefer -by declaring the map explicitly.) -.np -Default host name extension is consistent throughout processing; -version level one configurations turned off domain extension -(that is, adding the local domain name) -during certain points in processing. -Version level two configurations are expected to include a trailing dot -to indicate that the name is already canonical. -.np -Local names that are not aliases -are passed through a new distinguished ruleset five; -this can be used to append a local relay. -This behaviour can be prevented by resolving the local name -with an initial `@'. -That is, something that resolves to a local mailer and a user name of -.q vikki -will be passed through ruleset five, -but a user name of -.q @vikki -will have the `@' stripped, -will not be passed through ruleset five, -but will otherwise be treated the same as the prior example. -The expectation is that this might be used to implement a policy -where mail sent to -.q vikki -was handled by a central hub, -but mail sent to -.q vikki@localhost -was delivered directly. -.pp -Version level three files -allow # initiated comments on all lines. -Exceptions are backslash escaped # marks -and the $# syntax. -.pp -Version level four configurations -are completely equivalent to level three -for historical reasons. -.pp -Version level five configuration files -change the default definition of -.b $w -to be just the first component of the hostname. -.pp -Version level six configuration files -change many of the local processing options -(such as aliasing and matching the beginning of the address for -`|' characters) -to be mailer flags; -this allows fine-grained control over the special local processing. -Level six configuration files may also use long option names. -The -.b ColonOkInAddr -option (to allow colons in the local-part of addresses) -defaults -.b on -for lower numbered configuration files;

- return (EX_UNAVAILABLE); - } - if (MsgSize > 50000 && bitnset(M_LOCALMAILER, to\->q_mailer)) - { - usrerr("Message too large for non-local delivery"); - e\->e_flags |= EF_NORETURN; - return (EX_UNAVAILABLE); - } - return (EX_OK); -} -.sz -.)b -This would reject messages greater than 50000 bytes -unless they were local. -The -.i EF_NORETURN -flag can be set in -.i e\(->e_flags -to suppress the return of the actual body -of the message in the error return. -The actual use of this routine is highly dependent on the -implementation, -and use should be limited. -.sh 3 "Load Average Computation" -.pp -The routine -.i getla -should return an approximation of the current system load average -as an integer. -There are several versions included on compilation flags -as described above. -.sh 3 "New Database Map Classes" -.pp -New key maps can be added by creating a class initialization function -and a lookup function. -These are then added to the routine -.i setupmaps. -.pp -The initialization function is called as -.(b -\fIxxx\fP_map_init(MAP *map, char *args) -.)b -The -.i map -is an internal data structure. -The -.i args -is a pointer to the portion of the configuration file line -following the map class name; -flags and filenames can be extracted from this line. -The initialization function must return -.sm TRUE -if it successfully opened the map, -.sm FALSE -otherwise. -.pp -The lookup function is called as -.(b -\fIxxx\fP_map_lookup(MAP *map, char buf[], char **av, int *statp) -.)b -The -.i map -defines the map internally. -The -.i buf -has the input key. -This may be (and often is) used destructively. -The -.i av -is a list of arguments passed in from the rewrite line. -The lookup function should return a pointer to the new value. -IF the map lookup fails, -.i *statp -should be set to an exit status code; -in particular, it should be set to -.sm EX_TEMPFAIL -if recovery is to be attempted by the higher level code. -.sh 3 "Queueing Function" -.pp -The routine -.i shouldqueue -is called to decide if a message should be queued -or processed immediately. -Typically this compares the message priority to the current load average. -The default definition is: -.(b -bool -shouldqueue(pri, ctime) - long pri; - time_t ctime; -{ - if (CurrentLA < QueueLA) - return (FALSE); - return (pri > (QueueFactor / (CurrentLA \- QueueLA + 1))); -} -.)b -If the current load average -(global variable -.i CurrentLA , -which is set before this function is called) -is less than the low threshold load average -(option -.b x , -variable -.i QueueLA ), -.i shouldqueue -returns -.sm FALSE -immediately -(that is, it should -.i not -queue). -If the current load average exceeds the high threshold load average -(option -.b X , -variable -.i RefuseLA ), -.i shouldqueue -returns -.sm TRUE -immediately. -Otherwise, it computes the function based on the message priority, -the queue factor -(option -.b q , -global variable -.i QueueFactor ), -and the current and threshold load averages. -.pp -An implementation wishing to take the actual age of the message into account -can also use the -.i ctime -parameter, -which is the time that the message was first submitted to -.i sendmail . -Note that the -.i pri -parameter is already weighted -by the number of times the message has been tried -(although this tends to lower the priority of the message with time); -the expectation is that the -.i ctime -would be used as an -.q "escape clause" -to ensure that messages are eventually processed. -.sh 3 "Refusing Incoming SMTP Connections" -.pp -The function -.i refuseconnections -returns -.sm TRUE -if incoming SMTP connections should be refused. -The current implementation is based exclusively on the current load average -and the refuse load average option -(option -.b X , -global variable -.i RefuseLA ): -.(b -bool -refuseconnections() -{ - return (CurrentLA >= RefuseLA); -} -.)b -A more clever implementation -could look at more system resources. -.sh 3 "Load Average Computation" -.pp -The routine -.i getla -returns the current load average (as a rounded integer). -The distribution includes several possible implementations. -If you are porting to a new environment -you may need to add some new tweaks.\** -.(f -\**If you do, please send updates to -sendmail@Sendmail.ORG. -.)f -.sh 2 "Configuration in src/daemon.c" -.pp -The file -.i src/daemon.c -contains a number of routines that are dependent -on the local networking environment. -The version supplied assumes you have BSD style sockets. -.pp -In previous releases, -we recommended that you modify the routine -.i maphostname -if you wanted to generalize -.b $[ -\&...\& -.b $] -lookups. -We now recommend that you create a new keyed map instead. -.sh 1 "CHANGES IN VERSION 8" -.pp -The following summarizes changes -since the last commonly available version of -.i sendmail -(5.67). -For a detailed list, -consult the file -RELEASE_NOTES -in the root directory of the -.i sendmail -distribution. -.sh 2 "Connection Caching" -.pp -Instead of closing SMTP connections immediately, -those connections are cached for possible future use. -The advent of MX records made this effective for mailing lists; -in addition, -substantial performance improvements can be expected for queue processing. -.sh 2 "MX Piggybacking" -.pp -If two hosts with different names in a single message -happen to have the same set of MX hosts, -they can be sent in the same transaction. -Version 8 notices this and tries to batch the messages. -.sh 2 "RFC 1123 Compliance" -.pp -A number of changes have been made to make -.i sendmail -.q "conditionally compliant" -(that is, -.i sendmail -satisfies all of the -.q MUST -clauses and most but not all of the -.q SHOULD -clauses in RFC 1123). -.pp -The major areas of change are (numbers are RFC 1123 section numbers): -.nr ii \w'5.3.1.1\0\0'u -.ip 5.2.7 -Response to RCPT command is fast. -.ip 5.2.8 -Numeric IP addresses are logged in Received: lines. -.ip 5.2.17 -Self domain literal is properly handled. -.ip 5.3.2 -Better control over individual timeouts. -.ip 5.3.3 -Error messages are sent as -.q From:<> . -.ip 5.3.3 -Error messages are never sent to -.q <> . -.ip 5.3.3 -Route-addrs are pruned. -.lp -The areas in which -.i sendmail -is not -.q "unconditionally compliant" -are: -.ip 5.2.6 -.i Sendmail -does do header munging. -.ip 5.2.10 -.i Sendmail -doesn't always use the exact SMTP message text -as listed in RFC 821. -.ip 5.3.1.1 -.i Sendmail -doesn't guarantee only one connect for each host in queue runs. -.ip 5.3.1.1 -.i Sendmail -doesn't always provide adequate concurrency limits. -.sh 2 "Extended SMTP Support" -.pp -Version 8 includes both sending and receiving support for Extended -SMTP support as defined by RFC 1651 (basic) and RFC 1653 (SIZE); -and limited support for RFC 1652 (BODY). -.sh 2 "Eight-Bit Clean" -.pp -Previous versions of -.i sendmail -used the 0200 bit for quoting. -This version avoids that use. -However, for compatibility with RFC 822, -you can set option `7' to get seven bit stripping. -.pp -Individual mailers can still produce seven bit output using the -`7' mailer flag. -.sh 2 "User Database" -.pp -The user database is an as-yet experimental attempt -to provide unified large-site name support. -We are installing it at Berkeley; -future versions may show significant modifications. -.sh 2 "Improved BIND Support" -.pp -The BIND support, -particularly for MX records, -had a number of annoying -.q features -which have been removed in this release. -In particular, -these more tightly bind (pun intended) the name server to -.i sendmail , -so that the name server resolution rules are incorporated directly into -.b sendmail . -.sh 2 "Keyed Files" -.pp -Generalized keyed files is an idea taken directly from -.sm IDA -.i sendmail -(albeit with a completely different implementation). -They can be useful on large sites. -.pp -Version 8 also understands YP. -.sh 2 "Multi-Word Classes" -.pp -Classes can now be multiple words. -For example, -.(b -CShofmann.CS.Berkeley.EDU -.)b -allows you to match the entire string -.q hofmann.CS.Berkeley.EDU -using the single construct -.q $=S . -.sh 2 "Deferred Macro Expansion" -.pp -The -.b $& \c -.i x -construct has been adopted from -.sm IDA . -.sh 2 "IDENT Protocol Support" -.pp -The IDENT protocol as defined in RFC 1413 is supported. -.sh 2 "Parsing Bug Fixes" -.pp -A number of small bugs having to do with things like -backslash-escaped quotes inside of comments -have been fixed. -.sh 2 "Separate Envelope/Header Processing" -.pp -Since the From: line is passed in separately from the envelope sender, -these have both been made visible; -the -.b $g -macro is set to the envelope sender during processing -of mailer argument vectors -and the header sender during processing of headers. -.pp -It is also possible to specify separate per-mailer -envelope and header processing. -The -.b S enderRWSet -and -.b R ecipientRWset -arguments for mailers -can be specified as -.i envelope/header -to give different rewritings for envelope versus header addresses. -.sh 2 "Owner-List Propagates to Envelope" -.pp -When an alias has an associated owner\-list name, -that alias is used to change the envelope sender address. -This will cause downstream errors to be returned to that owner. -.sh 2 "Dynamic Header Allocation" -.pp -The fixed size limit on header lines has been eliminated. -.sh 2 "New Command Line Flags" -.pp -The -.b \-B -flag has been added to pass in body type information. -.pp -The -.b \-p -flag has been added -to pass in protocol information. -.pp -The -.b \-X -flag has been added -to allow logging of all protocol in and out of -.i sendmail -for debugging. -.pp -The -.b \-O -flag implies setting long-form options. -.sh 2 "Enhanced Command Line Flags" -.pp -The -.b \-q -flag can limit limit a queue run to specific recipients, senders, or queue ids -using -.b \-qR\c -.i substring , -.b \-qS\c -.i substring , -or -.b \-qI\c -.i substring -respectively. -.sh 2 "New and Old Configuration Line Types" -.pp -The -.b K -line has been added to declare database maps. -.pp -The -.b V -line has been added to declare the configuration version level. -.pp -The -.b M -line has a -.q D= -field that lets you change into a temporary directory while that mailer -is running. -It also has a -.q U= -field to allow you to set the user and group id to be used -when running the mailer. -.sh 2 "New Options" -.pp -Several new options have been added, -many to support new features, -others to allow tuning that was previously available -only by recompiling. -They are described in detail in Section 5.6. -Briefly, -.nr ii 0.5i -.ip b -Insist on a minimum number of disk blocks. -.ip C -Set checkpoint interval. -.ip E -Default error message. -.ip G -Enable GECOS matching. -.ip h -Maximum hop count. -.ip j -Send errors in MIME-encapsulated format. -.ip J -Forward file path. -.ip k -Connection cache size -.ip K -Connection cache lifetime. -.ip l -Enable Errors-To: header. -These headers violate RFC 1123; -this option is included to provide back compatibility -with old versions of -.i sendmail . -.ip O -Set incoming SMTP daemon options, such as an alternate SMTP port. -.ip p -Privacy options. -.ip R -Don't prune route-addrs. -.ip U -User database spec. -.ip V -Fallback -.q MX -host. -.ip w -.q "Best MX" -handling technique. -.ip 7 -Do not run eight bit clean. -.ip 8 -Eight bit data handling mode. -.sh 2 "Extended Options" -.pp -The -.b r -(read timeout), -.b I -(use BIND), -and -.b T -(queue timeout) -options have been extended to pass in more information. -.sh 2 "New Mailer Flags" -.pp -Several new mailer flags have been added. -.ip a -Try to use ESMTP when creating a connection. -If this is not set, -.i sendmail -will still try if the other end hints that it knows about ESMTP -in its greeting message; -this flag says to try even if it doesn't hint. -If the EHLO (extended hello) -command fails, -.i sendmail -falls back to old SMTP. -.ip A -Try the user part of addresses for this mailer as aliases. -.ip b -Ensure that there is a blank line at the end of all messages. -.ip c -Strip all comments from addresses; -this should only be used as a last resort -when dealing with cranky mailers. -.ip g -Never use the null sender as the envelope sender, -even when running SMTP. -Although this violates RFC 1123, -it may be necessary when you must deal with some obnoxious old hosts. -.ip k -Turn off the loopback check in the HELO protocol; -doing this may cause mailer loops. -.ip o -Always run the mailer as the recipient of the message. -.ip w -This user should have a passwd file entry. -.ip 5 -Try ruleset 5 if no local aliases. -.ip 7 -Strip all output to 7 bits. -.ip : -Check for :include: files. -.ip | -Check for |program addresses. -.ip / -Check for /file addresses. -.ip @ -Check this user against the user database. -.sh 2 "Long Option Names" -.pp -All options can be specified using long names, -and some new options can only be specified with long names. -.sh 2 "New Pre-Defined Macros" -.pp -The following macros are pre-defined: -.ip $k -The UUCP node name, -nominally from -.i uname (2) -call. -.ip $m -The domain part of our full hostname. -.ip $_ -The RFC 1413-provided sender address. -.sh 2 "New LHS Token" -.pp -Version 8 allows -.b $@ -on the Left Hand Side of an -.q R -line to match zero tokens. -This is intended to be used to match the null input. -.sh 2 "Bigger Defaults" -.pp -Version 8 allows up to 100 rulesets instead of 30. -It is recommended that rulesets 0\-9 be reserved for -.i sendmail 's -dedicated use in future releases. -.pp -The total number of MX records that can be used has been raised to 20. -.pp -The number of queued messages that can be handled at one time -has been raised from 600 to 1000. -.sh 2 "Different Default Tuning Parameters" -.pp -Version 8 has changed the default parameters -for tuning queue costs -to make the number of recipients more important -than the size of the message (for small messages). -This is reasonable if you are connected with reasonably fast links. -.sh 2 "Auto-Quoting in Addresses" -.pp -Previously, the -.q "Full Name " -syntax would generate incorrect protocol output -if -.q "Full Name" -had special characters such as dot. -This version puts quotes around such names. -.sh 2 "Symbolic Names On Error Mailer" -.pp -Several names have been built in to the $@ portion of the $#error -mailer. -.sh 2 "SMTP VRFY Doesn't Expand" -.pp -Previous versions of -.i sendmail -treated VRFY and EXPN the same. -In this version, -VRFY doesn't expand aliases or follow .forward files. -EXPN still does. -.pp -As an optimization, if you run with your default delivery mode being -queue-only or deliver-in-background, -the RCPT command will also not chase aliases and .forward files. -It will chase them when it processes the queue. -.sh 2 "[IPC] Mailers Allow Multiple Hosts" -.pp -When an address resolves to a mailer that has -.q [IPC] -as its -.q Path , -the $@ part (host name) -can be a colon-separated list of hosts instead of a single hostname. -This asks -.i sendmail -to search the list for the first entry that is available -exactly as though it were an MX record. -The intent is to route internal traffic through internal networks -without publishing an MX record to the net. -MX expansion is still done on the individual items. -.sh 2 "Aliases Extended" -.pp -The implementation has been merged with maps. -Among other things, -this supports NIS-based aliases. -.sh 2 "Portability and Security Enhancements" -.pp -A number of internal changes have been made to enhance portability. -.pp -Several fixes have been made to increase the paranoia factor. -.sh 2 "Miscellaneous Changes" -.pp -.i Sendmail -writes a -.i /etc/sendmail.pid -file with the current process id of the SMTP daemon. -.pp -Two people using the same program in their .forward file -are considered different -so that duplicate elimination doesn't delete one of them. -.pp -The -.i mailstats -program prints mailer names -and gets the location of the -.i sendmail.st -file from -.i /etc/sendmail.cf . -.pp -Many minor bugs have been fixed, such as handling of backslashes -inside of quotes. -.pp -A hook (ruleset 5) has been added -to allow rewriting of local addresses after aliasing. -.sh 1 "ACKNOWLEDGEMENTS" -.pp -I've worked on -.i sendmail -for many years, -and many employers have been remarkably patient -about letting me work on a large project -that was not part of my official job. -This includes time on the INGRES Project at -the University of California at Berkeley, -at Britton Lee, -and again on the Mammoth and Titan Projects at Berkeley. -.pp -Much of the second wave of improvements -should be credited to Bryan Costales of ICSI. -As he passed me drafts of his book on -.i sendmail -I was inspired to start working on things again. -Bryan was also available to bounce ideas off of. -.pp -Many, many people contributed chunks of code and ideas to -.i sendmail . -It has proven to be a group network effort. -Version 8 in particular was a group project. -The following people made notable contributions: -.(l -John Beck, Hewlett-Packard -Keith Bostic, CSRG, University of California, Berkeley -Andrew Cheng, Sun Microsystems -Michael J.

``sendmail@Sendmail.ORG'' list -and, by answering the bulk of the questions sent to that list, -have freed me up to do other work. -.++ A -.+c "COMMAND LINE FLAGS" -.ba 0 -.nr ii 1i -.pp -Arguments must be presented with flags before addresses. -The flags are: -.ip \-b\fIx\fP -Set operation mode to -.i x . -Operation modes are: -.(b -.ta 4n -m Deliver mail (default) -s Speak SMTP on input side -a\(dg ``Arpanet'' mode (get envelope sender information from header) -d Run as a daemon in background -D Run as a daemon in foreground -t Run in test mode -v Just verify addresses, don't collect or

with an error. -.ip \-n -Don't do aliasing or forwarding. -.ip "\-N \fInotifications\fP" -Tag all addresses being sent as wanting the indicated -.i notifications , -which consists of the word -.q NEVER -or a comma-separated list of -.q SUCCESS , -.q FAILURE , -and -.q DELAY -for successful delivery, -failure, -and a message that is stuck in a queue somewhere. -The default is -.q FAILURE,DELAY . -.ip "\-r\ \fIaddr\fP" -An obsolete form of -.b \-f . -.ip \-o\fIx\|value\fP -Set option -.i x -to the specified -.i value . -These options are described in Section 5.6. -.ip

"QUEUE FILE FORMATS" -.pp -This appendix describes the format of the queue files. -These files live in the directory defined by the -.b Q -option in the -.i sendmail.cf -file, usually -.i /var/spool/mqueue -or -.i /usr/spool/mqueue . -.pp -All queue files have the name -\fIx\fP\|\fBf\fP\fIAAA99999\fP -where -.i AAA99999 -is the -.i id -for this message -and the -.i x -is a type. -The first letter of the id encodes the hour of the day -that the message was received by the system -(with A being the hour between midnight and 1:00AM). -All files with the same id collectively define one message. -.pp -The types are: -.nr ii 0.5i -.ip d -The data file. -The message body (excluding the header) is kept in this file. -.ip q -The queue control file. -This file contains the information necessary to process the job. -.ip t -A temporary file. -These are an image of the -.b qf -file when it is being rebuilt. -It should be renamed to a -.b qf -file very quickly. -.ip x -A transcript file, -existing during the life of a session -showing everything that happens -during that session. -.pp -The -.b qf -file is structured as a series of lines -each beginning with a code letter. -The lines are as follows: -.ip V -The version number of the queue file format, -used to allow new -.i sendmail -binaries to read queue files created by older versions. -Defaults to version zero. -Must be the first line of the file if present. -.ip H -A header definition. -There may be any number of these lines. -The order is important: -they represent the order in the final message. -These use the same syntax -as header definitions in the configuration file. -.ip C -The controlling address. -The syntax is -.q localuser:aliasname . -Recipient addresses following this line -will be flagged so that deliveries will be run as the -.i localuser -(a user name from the /etc/passwd file); -.i aliasname -is the name of the alias that expanded to this address -(used for printing messages). -.ip Q -The ``original recipient'', -specified by the ORCPT= field in an ESMTP transaction. -Used exclusively for Delivery Status Notifications. -It applies only to the immediately following `R' line. -.ip R -A recipient address. -This will normally be completely aliased, -but is actually realiased when the job is processed. -There will be one line -for each recipient. -Version 1 qf files -also include a leading colon-terminated list of flags, -which can be -`S' to return a message on successful final delivery, -`F' to return a message on failure, -`D' to return a message if the message is delayed, -`B' to indicate that the body should be returned, -`N' to suppress returning the body, -and -`P' to declare this as a ``primary'' (command line or SMTP-session) address. -.ip S -The sender address. -There may only be one of these lines. -.ip T -The job creation time. -This is used to compute when to time out the job. -.ip P -The current message priority. -This is used to order the queue. -Higher numbers mean lower priorities. -The priority changes -as the message sits in the queue. -The initial priority depends on the message class -and the size of the message. -.ip M -A message. -This line is printed by the -.i mailq -command, -and is generally used to store status information. -It can contain any text. -.ip F -Flag bits, represented as one letter per flag. -Defined flag bits are -.b r -indicating that this is a response message -and -.b w -indicating that a warning message has been sent -announcing that the mail has been delayed. -.ip N -The total number of delivery attempts. -.ip K -The time (as seconds since January 1, 1970) -of the last delivery attempt. -.ip I -The i-number of the data file; -this can be used to recover your mail queue -after a disastrous disk crash. -.ip $ -A macro definition. -The values of certain macros -(as of this writing, only -.b $r -and -.b $s ) -are passed through to the queue run phase. -.ip B -The body type. -The remainder of the line is a text string defining the body type. -If this field is missing, -the body type is assumed to be -.q "undefined" -and no special processing is attempted. -Legal values are -.q 7BIT -and -.q 8BITMIME . -.ip O -The original MTS value (from the ESMTP transaction). -For Deliver Status Notifications only. -.ip Z -The original envelope id (from the ESMTP transaction). -For Deliver Status Notifications only. -.pp -As an example, -the following is a queue file sent to -.q eric@mammoth.Berkeley.EDU -and -.q bostic@okeeffe.CS.Berkeley.EDU \**: -.(f -\**This example is contrived and probably inaccurate

This file is -intended as a supplement to the CERT advisory CA-93:16.sendmail.vulnerability, -and to the software, smrsh.c, written by Eric Allman. - - - -The smrsh(8) program is intended as a replacement for /bin/sh in the -program mailer definition of sendmail(8). This README file describes -the steps needed to compile and install smrsh. - -smrsh is a restricted shell utility that provides the ability to -specify, through a configuration, an explicit list of executable -programs. When used in conjunction with sendmail, smrsh effectively -limits sendmail's scope of program execution to only those programs -specified in smrsh's configuration. - -smrsh has been written with portability in mind, and uses traditional -Unix library utilities. As such, smrsh should compile on most -Unix C compilers. - - - -To compile smrsh.c, use the following command: - -host.domain% cc -o smrsh smrsh.c - -For machines that provide dynamic linking, it is advisable to compile -smrsh without dynamic linking. As an example with the Sun Microsystems -compiler, you should compile with the -Bstatic option. - -host.domain% cc -Bstatic -o smrsh smrsh.c - - -Choose a directory that smrsh will reside in. We will use the traditional -/usr/local/etc directory for the remainder of this document. - -As root, install smrsh in /usr/local/etc directory, with mode 511. - -host.domain# mv smrsh /usr/local/etc -host.domain# chmod 511 /usr/local/etc/smrsh - - - -Next, determine the list of commands that smrsh should allow sendmail -to run. This list of allowable commands can be determined by: - - 1. examining your /etc/aliases file, to indicate what commands - are being used by the system. - - 2. surveying your host's .forward files, to determine what - commands users have specified. - -See the man page for aliases(5) if you are unfamiliar with the format of -these specifications. Additionally, you should include in the list, -popular commands such as /usr/ucb/vacation. - -You should NOT include interpreter programs such as sh(1), csh(1), -perl(1), uudecode(1) or the stream editor sed(1) in your list of -acceptable commands. - - -You will next need to create the directory /usr/adm/sm.bin and populate -it with the programs that your site feels are allowable for sendmail -to execute. This directory is explicitly specified in the source -code for smrsh, so changing this directory must be accompanied with -a change in smrsh.c. - - -You will have to be root to make these modifications. - -After creating the /usr/adm/sm.bin directory, either copy the programs -to the directory, or establish links to the allowable programs from -/usr/adm/sm.bin. Change the file permissions, so that these programs -can not be modified by non-root users. If you use links, you should -ensure that the target programs are not modifiable. - -To allow the popular vacation(1) program by creating a link in the -/usr/adm/sm.bin directory, you should: - -host.domain# cd /usr/adm/sm.bin -host.domain# ln -s /usr/ucb/vacation vacation - - - - -After populating the /usr/adm/sm.bin directory, you can now configure -sendmail to use the restricted shell. Save the current sendmail.cf -file prior to modifying it, as a prudent precaution. - -Typically, the program mailer is defined by a single line in the -sendmail configuration file, sendmail.cf. This file is traditionally -found in the /etc, /usr/lib or /etc/mail directories, depending on -the UNIX vendor. - -If you are unsure of the location of the actual sendmail configuration -file, a search of the strings(1) output of the sendmail binary, will -help to locate it. - -In order to configure sendmail to use smrsh, you must modify the Mprog -definition in the sendmail.cf file, by replacing the /bin/sh specification -with /usr/local/etc/smrsh. - -As an example: - -In most Sun Microsystems' sendmail.cf files, the line is: -Mprog, P=/bin/sh, F=lsDFMeuP, S=10, R=20, A=sh -c $u - -which should be changed to: -Mprog, P=/usr/local/etc/smrsh, F=lsDFMeuP, S=10, R=20, A=sh -c $u - ^^^^^^^^^^^^^^^^^^^^ - -A more generic line may be: -Mprog, P=/bin/sh, F=lsDFM, A=sh -c $u - -and should be changed to; -Mprog, P=/usr/local/etc/smrsh, F=lsDFM, A=sh -c $u - - -After modifying the Mprog definition in the sendmail.cf file, if a frozen -configuration file is being used, it is essential to create a new one. -You can determine if you need a frozen configuration by discovering -if a sendmail.fc file currently exists in either the /etc/, /usr/lib, -or /etc/mail directories. The specific location can be determined using -a search of the strings(1) output of the sendmail binary. - -In order to create a new frozen configuration, if it is required: -host.domain# /usr/lib/sendmail -bz - -Now re-start the sendmail process. An example of how to do this on -a typical system follows: - -host.domain# /usr/bin/ps aux | /usr/bin/grep sendmail -root 130 0.0 0.0 168 0 ?

It also creates a -subdirectory per object format, so that multiarchitecture support is -easy. In general this should be all you need. However, if for some -reason this doesn't work (e.g., NeXT systems don't have the "uname" -command) you may have to set up your compile environment by hand. - -The "Makefile"s in these directories are from 4.4 BSD, and hence -really only work properly if you are on a 4.4 system. In particular, -they use new syntax that will not be recognized on old make programs, -and some of them do things like ``.include ../../Makefile.inc'' to -pick up some system defines. If you are getting sendmail separately, -these files won't be included in the distribution, as they are -outside of the sendmail tree. - -Instead, you should use one of the other Makefiles, such as -Makefile.SunOS for a SunOS system, and so forth. These should -work with the version of make that is appropriate for that -system. All other Makefiles are in the "src/Makefiles" subdirectory. -They use the version of make that is native for that system. These -are the Makefiles that I use, and they have "Berkeley quirks" in them. -I can't guarantee that they will work unmodified in your environment. -In particular, Many of them include -I/usr/sww/include/db and --L/usr/sww/lib -- these are Berkeley's locations in the ``Software -Warehouse'' for the new database libraries, described below. You don't -have to remove these definitions if you don't have these directories, -but you may have to remove -DNEWDB from the DBMDEF definition. - -Please look for an appropriate Makefile before you start trying to -compile with Makefile or Makefile.dist. - -If you want to port the new Berkeley make, you can get it from -ftp.uu.net in the directory /systems/unix/bsd-sources/usr.bin/make. -Diffs and instructions for building this version of make under -SunOS 4.1.x are available on ftp.css.itd.umich.edu in -/pub/systems/sun/Net2-make-sun4.diff.Z. Diffs and instructions -for building this version of make under IBM AIX 3.2.4 are available -on ftp.uni-stuttgart.de in /sw/src/patches/bsd-make-rus-patches. -For Ultrix, try ftp.vix.com:~ftp/pub/patches/pmake-for-ultrix.Z. -Paul Southworth published a description of porting -this make in comp.unix.bsd. - -The complete text of the Makefile.inc that is in the parent of the -sendmail directory is: - - # @(#)Makefile.inc 8.1 (Berkeley) 6/6/93 - - BINDIR?= /usr/sbin - - -+----------------------+ -| DATABASE DEFINITIONS | -+----------------------+ - -There are several database formats that can be used for the alias files -and for general maps. When used for alias files they interact in an -attempt to be back compatible. - -The options are: - -NEWDB The new Berkeley DB package. Some systems (e.g., BSD/OS and - Digital UNIX 4.0) have this package pre-installed. If your - system does not have NEWDB installed, get version 1.85 - from http://www.sleepycat.com/packages/db.1.85.tar.gz. - DO NOT use Berkeley DB version 2.X with sendmail. DO NOT - use the version from the Net2 distribution. If you are - still running BSD/386 1.x, you will also need to define - OLD_NEWDB. -NDBM The older NDBM implementation -- the very old V7 DBM - implementation is no longer supported. -NIS Network Information Services. To use this you must have - NIS support on your system. -NISPLUS NIS+ (the revised NIS released with Solaris 2). You must - have NIS+ support on your system to use this flag. -HESIOD Support for Hesiod (from the DEC/Athena distribution). You - must already have Hesiod support on your system for this to - work. You may be able to get this to work with the MIT/Athena - version of Hesiod, but that's likely to be a lot of work. -LDAPMAP Lightweight Directory Lookup Protocol support. You will - have to install the UMich ldap and lber libraries to use - this flag. - ->>> NOTE WELL for NEWDB support: it is CRITICAL that you remove ndbm.o ->>> from libdb.a before you install it and DO NOT install ndbm.h if ->>> you want to get ndbm support. If you don't delete these, there is ->>> absolutely no point to including -DNDBM, since it will just get you ->>> another (inferior) API to the same format database. These files ->>> OVERRIDE calls to ndbm routines -- in particular, if you leave ndbm.h ->>> in, you can find yourself using the new db package even if you don't ->>> define NEWDB. ->>> ->>> Further note: DO NOT remove your existing /usr/include/ndbm.h -- ->>> you need that one. But do not install an updated ndbm.h in ->>> /usr/include, /usr/local/include, or anywhere else. - -If NEWDB and NDBM are defined (but not NIS), then sendmail will read -NDBM format alias files, but the next time a newaliases is run the -format will be converted to NEWDB; that format will be used forever -more. This is intended as a transition feature. - -If NEWDB, NDBM, and NIS are all defined and the name of the file includes -the string "/yp/", sendmail will rebuild BOTH the NEWDB and NDBM format -alias files. However, it will only read the NEWDB file; the NDBM format -file is used only by the NIS subsystem. This is needed because the NIS -maps on an NIS server are built directly from the NDBM files. - -If NDBM and NIS are defined (regardless of the definition of NEWDB), -and the filename includes the string "/yp/", sendmail adds the special -tokens "YP_LAST_MODIFIED" and "YP_MASTER_NAME", both of which are -required if the NDBM file is to be used as an NIS map. - -All of these flags are normally defined in the DBMDEF line in the -Makefile. - -If you define NEWDB or HESIOD you get the User Database (USERDB) -automatically. Generally you do want to have NEWDB for it to do -anything interesting. See above for getting the Berkeley "db" -package (i.e., NEWDB). There is no separate "user database" -package -- don't bother searching for it on the net. - -Hesiod and LDAP require libraries that may not be installed with your -system. These are outside of my ability to provide support. See the -"Quirks" section for more information. - - - -+---------------+ -| COMPILE FLAGS | -+---------------+ - -Whereever possible, I try to make sendmail pull in the correct -compilation options needed to compile on various environments based on -automatically defined symbols. Some machines don't seem to have useful -symbols available, requiring that a compilation flag be defined in -the Makefile; see the Makefiles subdirectory for the supported -architectures. - -If you are a system to which sendmail has already been ported you -should not have to touch the following symbols. But if you are porting, -you may have to tweak the following compilation flags in conf.h in order -to get it to compile and link properly: - -SYSTEM5 Adjust for System V (not necessarily Release 4). -SYS5SIGNALS Use System V signal semantics -- the signal handler - is automatically dropped when the signal is caught. - If this is not set, use POSIX/BSD semantics, where the - signal handler stays in force until an exec or an - explicit delete. Implied by SYSTEM5. -SYS5SETPGRP Use System V setpgrp() semantics. Implied by SYSTEM5. -HASFCHMOD Define this to one if you have the fchmod(2) system call. - This improves security. -HASFLOCK Set this if you prefer to use the flock(2) system call - rather than using fcntl-based locking. Fcntl locking - has some semantic gotchas, but many vendor systems - also interface it to lockd(8) to do NFS-style locking. - Unfortunately, may vendors implementations of fcntl locking - is just plain broken (e.g., locks are never released, - causing your sendmail to deadlock; when the kernel runs - out of locks your system crashes). For this reason, I - recommend always defining this unless you are absolutely - certain that your fcntl locking implementation really works. -HASUNAME Set if you have the "uname" system call. Implied by - SYSTEM5. -HASUNSETENV Define this if your system library has the "unsetenv" - subroutine. -HASSETSID Define this if you have the setsid(2) system call. This - is implied if your system appears to be POSIX compliant. -HASINITGROUPS Define this if you have the initgroups(3) routine. -HASSETVBUF Define this if you have the setvbuf(3) library call. - If you don't, setlinebuf will be used instead. This - defaults on if your compiler defines __STDC__. -HASSETREUID Define this if you have setreuid(2) ***AND*** root can - use setreuid to change to an arbitrary user. This second - condition is not satisfied on AIX 3.x. You may find that - your system has setresuid(2), (for example, on HP-UX) in - which case you will also have to #define setreuid(r, e) - to be the appropriate call. Some systems (such as Solaris) - have a compatibility routine that doesn't work properly, - but may have "saved user ids" properly implemented so you - can ``#define setreuid(r, e) seteuid(e)'' and have it work. - The important thing is that you have a call that will set - the effective uid independently of the real or saved uid - and be able to set the effective uid back again when done. - There's a test program in ../test/t_setreuid.c that will - try things on your system. Setting this improves the - security, since sendmail doesn't have to read .forward - and :include: files as root. There are certain attacks - that may be unpreventable without this call. -USESETEUID Define this to 1 if you have a seteuid(2) system call that - will allow root to set only the effective user id to an - arbitrary value ***AND*** you have saved user ids. This is - preferable to HASSETREUID if these conditions are fulfilled. - These are the semantics of the to-be-released revision of - Posix.1. The test program ../test/t_seteuid.c will try - this out on your system. If you define both HASSETREUID - and USESETEUID, the former is ignored. -HASLSTAT Define this if you have symbolic links (and thus the - lstat(2) system call). This improves security. Unlike - most other options, this one is on by default, so you - need to #undef it in conf.h if you don't have symbolic - links (these days everyone does). -HASSETRLIMIT Define this to 1 if you have the setrlimit(2) syscall. - You can define it to 0 to force it off. It is assumed - if you are running a BSD-like system. -HASULIMIT Define this if you have the ulimit(2) syscall (System V - style systems). HASSETRLIMIT overrides, as it is more - general. -HASWAITPID Define this if you have the waitpid(2) syscall. -HASGETDTABLESIZE - Define this if you have the getdtablesize(2) syscall. -HAS_ST_GEN Define this to 1 if your system has the st_gen field in - the stat structure (see stat(2)). -USESTRERROR Define this if you have the libc strerror function (which - should be declared in ), and it should be used - instead of sys_errlist. -NEEDGETOPT Define this if you need a reimplementation of getopt(3). - On some systems, getopt does very odd things if called - to scan the arguments twice. This flag will ask sendmail - to compile in a local version of getopt that works - properly. -NEEDSTRTOL Define this if your standard C library does not define - strtol(3). This will compile in a local version. -NEEDVPRINTF Define this if your standard C library does not define - vprintf(3). Note that the resulting fake implementation - is not very elegant and may not even work on some - architectures. -NEEDFSYNC Define this if your standard C library does not define - fsync(2). This will try to simulate the operation using - fcntl(2); if that is not available it does nothing, which - isn't great, but at least it compiles and runs. -HASGETUSERSHELL Define this to 1 if you have getusershell(3) in your - standard C library. If this is not defined, or is defined - to be 0, sendmail will scan the /etc/shells file (no - NIS-style support, defaults to /bin/sh and /bin/csh if - that file does not exist) to get a list of unrestricted - user shells. This is used to determine whether users - are allowed to forward their mail to a program or a file. -NEEDPUTENV Define this if your system needs am emulation of the - putenv(3) call. Define to 1 to implement it in terms - of setenv(3) or to 2 to do it in terms of primitives. -NOFTRUNCATE Define this if you don't have the ftruncate(2) syscall. - If you don't have this system call, there is an unavoidable - race condition that occurs when creating alias databases. -GIDSET_T The type of entries in a gidset passed as the second - argument to getgroups(2). Historically this has been an - int, so this is the default, but some systems (such as - IRIX) pass it as a gid_t, which is an unsigned short. - This will make a difference, so it is important to get - this right! However, it is only an issue if you have - group sets. -SLEEP_T The type returned by the system sleep() function. - Defaults to "unsigned int". Don't worry about this - if you don't have compilation problems. -ARBPTR_T The type of an arbitrary pointer -- defaults to "void *". - If you are an very old compiler you may need to define - this to be "char *". -SOCKADDR_LEN_T The type used for the third parameter to accept(2), - getsockname(2), and getpeername(2), representing the - length of a struct sockaddr. Defaults to int. -SOCKOPT_LEN_T The type used for the fifth parameter to getsockopt(2) - and setsockopt(2), representing the length of the option - buffer. Defaults to int. -LA_TYPE The type of load average your kernel supports. These - can be one of: - LA_ZERO (1) -- it always returns the load average as - "zero" (and does so on all architectures). - LA_INT (2) to read /dev/kmem for the symbol avenrun and - interpret as a long integer. - LA_FLOAT (3) same, but interpret the result as a floating - point number. - LA_SHORT (6) to interpret as a short integer. - LA_SUBR (4) if you have the getloadavg(3) routine in your - system library. - LA_MACH (5) to use MACH-style load averages (calls - processor_set_info()), - LA_PROCSTR (7) to read /proc/loadavg and interpret it - as a string representing a floating-point - number (Linux-style). - LA_READKSYM (8) is an implementation suitable for some - versions of SVr4 that uses the MIOC_READKSYM ioctl - call to read /dev/kmem. - LA_DGUX (9) is a special implementation for DG/UX that uses - the dg_sys_info system call. - LA_HPUX (10) is an HP-UX specific version that uses the - pstat_getdynamic system call. - LA_IRIX6 (11) is an IRIX 6.x specific version that adapts - to 32 or 64 bit kernels; it is otherwise very similar - to LA_INT. - LA_KSTAT (12) uses the (Solaris-specific) kstat(3k) - implementation. - LA_DEVSHORT (13) reads a short from a system file (default: - /dev/table/avenrun) and scales it in the same manner - as LA_SHORT. - LA_INT, LA_SHORT, LA_FLOAT, and LA_READKSYM have several - other parameters that they try to divine: the name of your - kernel, the name of the variable in the kernel to examine, - the number of bits of precision in a fixed point load average, - and so forth. LA_DEVSHORT uses _PATH_AVENRUN to find the - device to be read to find the load average. - In desperation, use LA_ZERO. The actual code is in - conf.c -- it can be tweaked if you are brave. -FSHIFT For LA_INT, LA_SHORT, and LA_READKSYM, this is the number - of bits of load average after the binary point -- i.e., - the number of bits to shift right in order to scale the - integer to get the true integer load average. Defaults to 8. -_PATH_UNIX The path to your kernel. Needed only for LA_INT, LA_SHORT, - and LA_FLOAT. Defaults to "/unix" on System V, "/vmunix" - everywhere else. -LA_AVENRUN For LA_INT, LA_SHORT, and LA_FLOAT, the name of the kernel - variable that holds the load average. Defaults to "avenrun" - on System V, "_avenrun" everywhere else. -SFS_TYPE Encodes how your kernel can locate the amount of free - space on a disk partition. This can be set to SFS_NONE - (0) if you have no way of getting this information, - SFS_USTAT (1) if you have the ustat(2) system call, - SFS_4ARGS (2) if you have a four-argument statfs(2) - system call (and the include file is ), - SFS_VFS (3), SFS_MOUNT (4), SFS_STATFS (5) if you have - the two-argument statfs(2) system call with includes in - , , or respectively, - or SFS_STATVFS (6) if you have the two-argument statvfs(2) - call. The default if nothing is defined is SFS_NONE. -SFS_BAVAIL with SFS_4ARGS you can also set SFS_BAVAIL to the field name - in the statfs structure that holds the useful information; - this defaults to f_bavail. -SPT_TYPE Encodes how your system can display what a process is doing - on a ps(1) command (SPT stands for Set Process Title). Can - be set to: - SPT_NONE (0) -- Don't try to set the process title at all. - SPT_REUSEARGV (1) -- Pad out your argv with the information; - this is the default if none specified. - SPT_BUILTIN (2) -- The system library has setproctitle. - SPT_PSTAT (3) -- Use the PSTAT_SETCMD option to pstat(2) - to set the process title; this is used by HP-UX. - SPT_PSSTRINGS (4) -- Use the magic PS_STRINGS pointer (4.4BSD). - SPT_SYSMIPS (5) -- Use sysmips() supported by NEWS-OS 6. - SPT_SCO (6) -- Write kernel u. area. - SPT_CHANGEARGV (7) -- Write pointers to our own strings into - the existing argv vector. -SPT_PADCHAR Character used to pad the process title; if undefined, - the space character (0x20) is used. This is ignored if - SPT_TYPE != SPT_REUSEARGV -ERRLIST_PREDEFINED - If set, assumes that some header file defines sys_errlist. - This may be needed if you get type conflicts on this - variable -- otherwise don't worry about it. -WAITUNION The wait(2) routine takes a "union wait" argument instead - of an integer argument. This is for compatibility with - old versions of BSD. -SCANF You can set this to extend the F command to accept a - scanf string -- this gives you a primitive parser for - class definitions -- BUT it can make you vulnerable to - core dumps if the target file is poorly formed. -SYSLOG_BUFSIZE You can define this to be the size of the buffer that - syslog accepts. If it is not defined, it assumes a - 1024-byte buffer. If the buffer is very small (under - 256 bytes) the log message format changes -- each - e-mail message will log many more messages, since it - will log each piece of information as a separate line - in syslog. -BROKEN_RES_SEARCH - On Ultrix (and maybe other systems?) if you use the - res_search routine with an unknown host name, it returns - -1 but sets h_errno to 0 instead of HOST_NOT_FOUND. If - you set this, sendmail considers 0 to be the same as - HOST_NOT_FOUND. -NAMELISTMASK If defined, values returned by nlist(3) are masked - against this value before use -- a common value is - 0x7fffffff to strip off the top bit. -BSD4_4_SOCKADDR If defined, socket addresses have an sa_len field that - defines the length of this address. -SAFENFSPATHCONF Set this to 1 if and only if you have verified that a - pathconf(2) call with _PC_CHOWN_RESTRICTED argument on an - NFS filesystem where the underlying system allows users to - give away files to other users returns <= 0. Be sure you - try both on NFS V2 and V3. Some systems assume that their - local policy apply to NFS servers -- this is a bad - assumption! The test/t_pathconf.c program will try this - for you -- you have to run it in a directory that is - mounted from a server that allows file giveaway. -SIOCGIFCONF_IS_BROKEN - Set this if your system has an SIOCGIFCONF ioctl defined, - but it doesn't behave the same way as "most" systems (BSD, - Solaris, SunOS, HP-UX, etc.) -SIOCGIFNUM_IS_BROKEN - Set this if your system has an SIOCGIFNUM ioctl defined, - but it doesn't behave the same way as "most" systems - (Solaris, HP-UX). - - - -+-----------------------+ -| COMPILE-TIME FEATURES | -+-----------------------+ - -There are a bunch of features that you can decide to compile in, such -as selecting various database packages and special protocol support. -Several are assumed based on other compilation flags -- if you want to -"un-assume" something, you probably need to edit conf.h. Compilation -flags that add support for special features include: - -NDBM Include support for "new" DBM library for aliases and maps. - Normally defined in the Makefile. -NEWDB Include support for Berkeley "db" package (hash & btree) - for aliases and maps. Normally defined in the Makefile. -OLD_NEWDB If non-zero, the version of NEWDB you have is the old - one that does not include the "fd" call. This call was - added in version 1.5 of the Berkeley DB code. If you - use -DOLD_NEWDB=0 it forces you to use the new interface. -NIS Define this to get NIS (YP) support for aliases and maps. - Normally defined in the Makefile. -NISPLUS Define this to get NIS+ support for aliases and maps. - Normally defined in the Makefile. -HESIOD Define this to get Hesiod support for aliases and maps. - Normally defined in the Makefile. -NETINFO Define this to get NeXT NetInfo support for aliases and maps. - Normally defined in the Makefile. -USERDB Define this to 1 to include support for the User Information - Database. Implied by NEWDB or HESIOD. You can use - -DUSERDB=0 to explicitly turn it off. -IDENTPROTO Define this as 1 to get IDENT (RFC 1413) protocol support. - This is assumed unless you are running on Ultrix or - HP-UX, both of which have a problem in the UDP - implementation. You can define it to be 0 to explicitly - turn off IDENT protocol support. If defined off, the code - is actually still compiled in, but it defaults off; you - can turn it on by setting the IDENT timeout to 30s in the - configuration file. -IP_SRCROUTE Define this to 1 to get IP source routing information - displayed in the Received: header. This is assumed on - most systems, but some (e.g., Ultrix) apparently have a - broken version of getsockopt that doesn't properly - support the IP_OPTIONS call. You probably want this if - your OS can cope with it. Symptoms of failure will be that - it won't compile properly (that is, no support for fetching - IP_OPTIONs), or it compiles but source-routed TCP connections - either refuse to open or open and hang for no apparent reason. - Ultrix and AIX3 are known to fail this way. -LOG Set this to get syslog(3) support. Defined by default - in conf.h. You want this if at all possible. -NETINET Set this to get TCP/IP support. Defined by default - in conf.h. You probably want this. -NETISO Define this to get ISO networking support. -NETUNIX Define this to get Unix domain networking support. Defined - by default. A few bizarre systems (SCO, ISC, Altos) don't - support this networking domain. -SMTP Define this to get the SMTP code. Implied by NETINET - or NETISO. -NAMED_BIND If non-zero, include DNS (name daemon) support, including - MX support. The specs say you must use this if you run - SMTP. You don't have to be running a name server daemon - on your machine to need this -- any use of the DNS resolver, - including remote access to another machine, requires this - option. Defined by default in conf.h. Define it to zero - ONLY on machines that do not use DNS in any way. -QUEUE Define this to get queueing code. Implied by NETINET - or NETISO; required by SMTP. This gives you other good - stuff -- it should be on. -DAEMON Define this to get general network support. Implied by - NETINET or NETISO. Defined by default in conf.h. You - almost certainly want it on. -MATCHGECOS Permit fuzzy matching of user names against the full - name (GECOS) field in the /etc/passwd file. This should - probably be on, since you can disable it from the config - file if you want to. Defined by default in conf.h. -MIME8TO7 If non-zero, include 8 to 7 bit MIME conversions. This - also controls advertisement of 8BITMIME in the ESMTP - startup dialogue. -MIME7TO8 If non-zero, include 7 to 8 bit MIME conversions. -HES_GETMAILHOST Define this to 1 if you are using Hesiod with the - hes_getmailhost() routine. This is included with the MIT - Hesiod distribution, but not with the DEC Hesiod distribution. -XDEBUG Do additional internal checking. These don't cost too - much; you might as well leave this on. -TCPWRAPPERS Turns on support for the TCP wrappers library (-lwrap). - See below for further information. -SECUREWARE Enable calls to the SecureWare luid enabling/changing routines. - SecureWare is a C2 security package added to several UNIX's - (notably ConvexOS) to get a C2 Secure system. This - option causes mail delivery to be done with the luid of the - recipient. -SHARE_V1 Support for the fair share scheduler, version 1. Setting to - 1 causes final delivery to be done using the recipients - resource limitations. So far as I know, this is only - supported on ConvexOS. - - -+---------------------+ -| DNS/RESOLVER ISSUES | -+---------------------+ - -Many systems have old versions of the resolver library. At a minimum, -you should be running BIND 4.8.3; older versions may compile, but they -have known bugs that should give you pause. - -Common problems in old versions include "undefined" errors for -dn_skipname. - -Some people have had a problem with BIND 4.9; it uses some routines -that it expects to be externally defined such as strerror(). It may -help to link with "-l44bsd" to solve this problem. This has apparently -been fixed in later versions of BIND, starting around 4.9.3. In other -words, if you use 4.9.0 through 4.9.2, you need -l44bsd; for earlier or -later versions, you do not. - -!PLEASE! be sure to link with the same version of the resolver as -the header files you used -- some people have used the 4.9 headers -and linked with BIND 4.8 or vice versa, and it doesn't work. -Unfortunately, it doesn't fail in an obvious way -- things just -subtly don't work. - -WILDCARD MX RECORDS ARE A BAD IDEA! The only situation in which they -work reliably is if you have two versions of DNS, one in the real world -which has a wildcard pointing to your firewall, and a completely -different version of the database internally that does not include -wildcard MX records that match your domain.

This info is thanks to Brian Bartholomew - of I-Kinetics, Inc. - -SunOS 4.0.2 (Sun 386i) - Date: Fri, 25 Aug 1995 11:13:58 +0200 (MET DST) - From: teus@oce.nl - - Sendmail 8.7.Beta.12 compiles and runs nearly out of the box with the - following changes: - * Don't use /usr/5bin in your PATH, but make /usr/5bin/uname - available as "uname" command. - * Use the defines "-DBSD4_3 -DNAMED_BIND=0" in the - Makefile.SunOS.4.0, which is selected via the "uname" command. - I recommend to make available the db-library on the system first - (and change the Makefile to use this library). - Note that the sendmail.cf and aliases files are found in /etc. - -SunOS 4.1.3, 4.1.3_U1 - Sendmail causes crashes on SunOS 4.1.3 and 4.1.3_U1. According - to Sun bug number 1077939: - - If an application does a getsockopt() on a SOCK_STREAM (TCP) socket - after the other side of the connection has sent a TCP RESET for - the stream, the kernel gets a Bus Trap in the tcp_ctloutput() or - ip_ctloutput() routine. - - For 4.1.3, this is fixed in patch 100584-08, available on the - Sunsolve 2.7.1 or later CDs. For 4.1.3_U1, this is fixed in patch - 101790-01 (SunOS 4.1.3_U1: TCP socket and reset problems). - -Solaris 2.x (SunOS 5.x) - To compile for Solaris, the Makefile chosen by makesendmail must - include a SOLARIS definition which reflects the Solaris version - (i.e. -DSOLARIS=20400 for 2.4 or -DSOLARIS=20501 for 2.5.1). - If you are using gcc, make sure -I/usr/include is not used (or - it might complain about TopFrame). If you are using Sun's cc, - make sure /opt/SUNWspro/bin/cc is used instead of /usr/ucb/cc - (or it might complain about tm_zone). - - To the best of my knowledge, Solaris does not have the - gethostbyname problem described above. However, it does - have another one: - - From a correspondent: - - For solaris 2.2, I have - - hosts: files dns - - in /etc/nsswitch.conf and /etc/hosts has to have the fully - qualified host name. I think "files" has to be before "dns" - in /etc/nsswitch.conf during bootup. - - From another correspondent: - - When running sendmail under Solaris, the gethostbyname() - hack in conf.c which should perform proper canonicalization - of host names could fail. Result: the host name is not - canonicalized despite the hack, and you'll have to define $j - and $m in sendmail.cf somewhere. - - The reason could be that /etc/nsswitch.conf is improperly - configured (at least from sendmail's point of view). For - example, the line - - hosts: files nisplus dns - - will make gethostbyname() look in /etc/hosts first, then ask - nisplus, then dns. However, if /etc/hosts does not contain - the full canonicalized hostname, then no amount of - gethostbyname()s will work. - - Solution (or rather, a workaround): Ask nisplus first, then - dns, then local files: - - hosts: nisplus dns [NOTFOUND=return] files - - The Solaris "syslog" function is apparently limited to something - about 90 characters because of a kernel limitation. If you have - source code, you can probably up this number. You can get patches - that fix this problem: the patch ids are: - - Solaris 2.1 100834 - Solaris 2.2 100999 - Solaris 2.3 101318 - - Be sure you have the appropriate patch installed or you won't - see system logging. - -Solaris 2.4 (SunOS 5.4) - If you include /usr/lib at the end of your LD_LIBRARY_PATH you run - the risk of getting the wrong libraries under some circumstances. - This is because of a new feature in Solaris 2.4, described by - Rod.Evans@Eng.Sun.COM: - - >> Prior to SunOS 5.4, any LD_LIBRARY_PATH setting was ignored by the - >> runtime linker if the application was setxid (secure), thus your - >> applications search path would be: - >> - >> /usr/local/lib LD_LIBRARY_PATH component - IGNORED - >> /usr/lib LD_LIBRARY_PATH component - IGNORED - >> /usr/local/lib RPATH - honored - >> /usr/lib RPATH - honored - >> - >> the effect is that path 3 would be the first used, and this would - >> satisfy your resolv.so lookup. - >> - >> In SunOS 5.4 we made the LD_LIBRARY_PATH a little more flexible. - >> People who developed setxid applications wanted to be able to alter - >> the library search path to some degree to allow for their own - >> testing and debugging mechanisms.

This problem is fixed in sendmail - 8.8.5. - -Solaris 2.5.1 (SunOS 5.5.1) and 2.6 (SunOS 5.6) - Apparently Solaris 2.5.1 patch 103663-01 installs a new - /usr/include/resolv.h file that defines the __P macro without - checking to see if it is already defined. This new resolv.h is also - included in the Solaris 2.6 distribution. This causes compile - warnings such as: - - In file included from daemon.c:51: - /usr/include/resolv.h:208: warning: `__P' redefined - cdefs.h:58: warning: this is the location of the previous definition - - These warnings can be safely ignored or you can create a resolv.h - file in the obj.SunOS.5.5.1.* or obj.SunOS.5.6.* directory that reads: - - #undef __P - #include "/usr/include/resolv.h" - - Sun is aware of the problem (Sun bug ID 4081053) and it will be fixed - in a to-be-released patch. - -Ultrix - By default, the IDENT protocol is turned off on Ultrix. If you - are running Ultrix 4.4 or later, or if you have included patch - CXO-8919 for Ultrix 4.2 or 4.3 to fix the TCP problem, you can turn - IDENT on in the configuration file by setting the "ident" timeout - to 30 seconds. - -Digital UNIX (formerly DEC OSF/1) - If you are compiling on OSF/1 (DEC Alpha), you must use - -L/usr/shlib (otherwise it core dumps on startup). You may also - need -mld to get the nlist() function, although some versions - apparently don't need this. - - Also, the enclosed makefile removed /usr/sbin/smtpd; if you need - it, just create the link to the sendmail binary. - - On DEC OSF/1 3.2 or earlier, the MatchGECOS option doesn't work - properly due to a bug in the getpw* routines. If you want to use - this, use -DDEC_OSF_BROKEN_GETPWENT=1. The problem is fixed in 3.2C. - - On Digital UNIX 4.0 and later, Berkeley DB is included with the - operating system and already has the ndbm.o module removed. However, - Digital has modified the original Berkeley DB db.h include file. - This results in the following warning while compiling map.c and udb.c: - - cc: Warning: /usr/include/db.h, line 74: The redefinition of the macro - "__signed" conflicts with a current definition because the replacement - lists differ. The redefinition is now in effect. - #define __signed signed - ------------------------^ - - This warning can be ignored. - -IRIX - The header files on SGI IRIX are completely prototyped, and as - a result you can sometimes get some warning messages during - compilation. These can be ignored. There are two errors in - deliver only if you are using gcc, both of the form ``warning: - passing arg N of `execve' from incompatible pointer type''. - Also, if you compile with -DNIS, you will get a complaint - about a declaration of struct dom_binding in a prototype - when compiling map.c; this is not important because the - function being prototyped is not used in that file. - - In order to compile sendmail you will have had to install - the developers' option in order to get the necessary include - files. - - If you compile with -lmalloc (the fast memory allocator), you may - get warning messages such as the following: - - ld32: WARNING 85: definition of _calloc in /usr/lib32/libmalloc.so - preempts that definition in /usr/lib32/mips3/libc.so. - ld32: WARNING 85: definition of _malloc in /usr/lib32/libmalloc.so - preempts that definition in /usr/lib32/mips3/libc.so. - ld32: WARNING 85: definition of _realloc in /usr/lib32/libmalloc.so - preempts that definition in /usr/lib32/mips3/libc.so. - ld32: WARNING 85: definition of _free in /usr/lib32/libmalloc.so - preempts that definition in /usr/lib32/mips3/libc.so. - ld32: WARNING 85: definition of _cfree in /usr/lib32/libmalloc.so - preempts that definition in /usr/lib32/mips3/libc.so. - - These are unavoidable and innocuous -- just ignore them. - - According to Dave Sill , there is a version of the - Berkeley db library patched to run on Irix 6.2 available from - http://reality.sgi.com/ariel/db-1.85-irix.tar.Z . - -NeXT or NEXTSTEP - NEXTSTEP 3.3 and earlier ship with the old DBM library. You will - need to acquire the new Berkeley DB from ftp.cs.berkeley.edu. - Install it in /usr/local/{lib,include}. - - If you are compiling on NEXTSTEP, you will have to create an - empty file "unistd.h" and create a file "dirent.h" containing: - - #include - #define dirent direct - - (The Makefile.NeXT should try to do both of these for you.) - - Apparently, there is a bug in getservbyname on Nextstep 3.0 - that causes it to fail under some circumstances with the - message "SYSERR: service "smtp" unknown" logged. You should - be able to work around this by including the line: - - OOPort=25 - - in your .cf file. - - You may have to use -DNeXT. - -BSDI (BSD/386) 1.0, NetBSD 0.9, FreeBSD 1.0 - The "m4" from BSDI won't handle the config files properly. - I haven't had a chance to test this myself. - - The M4 shipped in FreeBSD and NetBSD 0.9 don't handle the config - files properly. One must use either GNU m4 1.1 or the PD-M4 - recently posted in comp.os.386bsd.bugs (and maybe others). - NetBSD-current includes the PD-M4 (as stated in the NetBSD file - CHANGES). - - FreeBSD 1.0 RELEASE has uname(2) now. Use -DUSEUNAME in order to - use it (look into Makefile.FreeBSD). NetBSD-current may have - it too but it has not been verified. - - You cannot port the latest version of the Berkeley db library - and use it with sendmail without recompiling the world. This - is because C library routines use the older version which have - incompatible header files -- the result is that it can't read - other system files, such as /etc/passwd, unless you use the - new db format throughout your system. You should normally just - use the version of db supplied in your release. You may need - to use -DOLD_NEWDB=1 to make this work -- this turns off some - new interface calls (for file locking) that are not in older - versions of db. You'll get compile errors if you need this - flag and don't have it set. - -4.3BSD - If you are running a "virgin" version of 4.3BSD, you'll have - a very old resolver and be missing some header files. The - header files are simple -- create empty versions and everything - will work fine. For the resolver you should really port a new - version (4.8.3 or later) of the resolver; 4.9 is available on - gatekeeper.DEC.COM in pub/BSD/bind/4.9. If you are really - determined to continue to use your old, buggy version (or as - a shortcut to get sendmail working -- I'm sure you have the - best intentions to port a modern version of BIND), you can - copy ../contrib/oldbind.compat.c into src and add - oldbind.compat.o to OBJADD in the Makefile. - -A/UX - Date: Tue, 12 Oct 1993 18:28:28 -0400 (EDT) - From: "Eric C. Hagberg" - Subject: Fix for A/UX ndbm - - I guess this isn't really a sendmail bug, however, it is something - that A/UX users should be aware of when compiling sendmail 8.6. - - Apparently, the calls that sendmail is using to the ndbm routines - in A/UX 3.0.x contain calls to "broken" routines, in that the - aliases database will break when it gets "just a little big" - (sorry I don't have exact numbers here, but it broke somewhere - around 20-25 aliases for me.), making all aliases non-functional - after exceeding this point. - - What I did was to get the gnu-dbm-1.6 package, compile it, and - then re-compile sendmail with "-lgdbm", "-DNDBM", and using the - ndbm.h header file that comes with the gnu-package. This makes - things behave properly. - [NOTE: see comment above about GDBM] - - I suppose porting the New Berkeley db package is another route, - however, I made a quick attempt at it, and found it difficult - (not easy at least); the gnu-dbm package "configured" and - compiled easily. - -SCO Unix - From: Thomas Essebier - Organisation: Stallion Technologies Pty Ltd. - - It will probably help those who are trying to configure sendmail 8.6.9 - to know that if they are on SCO, they had better set - OI-dnsrch - or they will core dump as soon as they try to use the resolver. - ie. although SCO has _res.dnsrch defined, and is kinda BIND 4.8.3, it - does not inititialise it, nor does it understand 'search' in - /etc/named.boot. - - sigh - - -DG/UX - Doug Anderson has successfully run - V8 on the DG/UX 5.4.2 and 5.4R3.x platforms under heavy usage. - Originally, the DG /bin/mail program wasn't compatible with - the V8 sendmail, since the DG /bin/mail requires the environment - variable "_FORCE_MAIL_LOCAL_=yes" be set. Version 8.7 now includes - this in the environment before invoking the local mailer. Some - have used procmail to avoid this problem in the past. It works - but some have experienced file locking problems with their DG/UX - ports of procmail. - -Apollo DomainOS - If you are compiling on Apollo, you will have to create an empty - file "unistd.h" and create a file "dirent.h" containing: - - #include - #define dirent direct - - (The Makefile.DomainOS will attempt to do both of these for you.) - -HP-UX 8.00 - Date: Mon, 24 Jan 1994 13:25:45 +0200 - From: Kimmo Suominen - Subject: 8.6.5 w/ HP-UX 8.00 on s300 - - Just compiled and fought with sendmail 8.6.5 on a HP9000/360 (ie. a - series 300 machine) running HP-UX 8.00. - - I was getting segmentation fault when delivering to a local user. - With debugging I saw it was faulting when doing _free@libc... *sigh* - It seems the new implementation of malloc on s300 is buggy as of 8.0, - so I tried out the one in -lmalloc (malloc(3X)). With that it seems - to work just dandy. - - When linking, you will get the following error: - - ld: multiply defined symbol _freespace in file /usr/lib/libmalloc.a - - but you can just ignore it. You might want to add this info to the - README file for the future... - -Linux - Something broke between versions 0.99.13 and 0.99.14 of Linux: - the flock() system call gives errors. If you are running .14, - you must not use flock. You can do this with -DHASFLOCK=0. - - Around the inclusion of bind-4.9.3 & linux libc-4.6.20, the - initialization of the _res structure changed. If /etc/hosts.conf - was configured as "hosts, bind" the resolver code could return - "Name server failure" errors. This is supposedly fixed in - later versions of libc (>= 4.6.29?), and later versions of - sendmail (> 8.6.10) try to work around the problem. - - Some older versions (< 4.6.20?) of the libc/include files conflict - with sendmail's version of cdefs.h. Deleting sendmail's version - on those systems should be non-harmful, and new versions don't care. - - Sendmail assumes that libc has snprintf, which has been true since - libc 4.7.0. If you are running an older version, you will need to - use -DHASSNPRINTF=0 in the Makefile. If may be able to use -lbsd - (which includes snprintf) instead of turning this off on versions - of libc between 4.4.4 and 4.7.0 (snprintf improves security, so - you want to use this if at all possible). - - NOTE ON LINUX & BIND: By default, the Makefiles for linux include - header files in /usr/local/include and libraries in /usr/local/lib. - If you've installed BIND on your system, the header files typically - end up in the search path and you need to add "-lresolv" to the - LIBS line in your Makefile. Really old versions may need to include - "-l44bsd" as well (particularly if the link phase complains about - missing strcasecmp, strncasecmp or strpbrk). Complaints about an - undefined reference to `__dn_skipname' in domain.o are a sure sign - that you need to add -lresolv to LIBS. Newer versions of linux - are basically threaded BIND, so you may or may not see complaints - if you accidentally mix BIND headers/libraries with virginal libc. - If you have BIND headers in /usr/local/include (resolv.h, etc) - you *should* be adding -lresolv to LIBS. Data structures may change - and you'd be asking for a core dump. - -AIX 3.x - This version of sendmail does not support MB, MG, and MR resource - records, which are supported by AIX sendmail. - - Several people have reported that the IBM-supplied named returns - fairly random results -- the named should be replaced. It is not - necessary to replace the resolver, which will simplify installation. - A new BIND resolver can be found at http://www.isc.org/isc/. - -AIX 3.1.x - The supplied load average code only works correctly for AIX 3.2.x. - For 3.1, use -DLA_TYPE=LA_SUBR and get the latest ``monitor'' - package by Jussi Maki from ftp.funet.fi in the - directory pub/unix/AIX/rs6000/monitor-1.12.tar.Z; use the loadavgd - daemon, and the getloadavg subroutine supplied with that package. - If you don't care about load average throttling, just turn off - load average checking using -DLA_TYPE=LA_ZERO. - -AIX 2.2.1 - Date: Mon Dec 4 14:14:56 CST 1995 - From: Mark Whetzel - Subject: Porting sendmail 8.7.2 to AIX V2 on the RT. - - This version of sendmail does not support MB, MG, and MR resource - records, which are supported by AIX sendmail. - - AIX V2 on the RT does not have 'paths.h'. Create a null - file in the 'obj' directory to remove this compile error. - - A patch file is needed to get the BSD 'db' library to compile - for AIX/RT. I have sent the necessary updates to the author, - but they may not be immediately available. - - The original AIX/RT resolver libraries are very old, and you - should get the latest BIND to replace it. The 4.8.3 version - has been tested, but 4.9.x is out and should work. - - To make the load average code work correctly requires an - external routine, as the kernel does not maintain system - load averages, similar to AIX V3.1.x. A reverse port of the - older 1.05 'monitor' load average daemon code written by - Jussi Maki that will work on AIX V2 for the RT is available - by E-mail to Mark Whetzel . - That code depends on an external daemon to collect system - load information, and the external routine 'getloadavg', - that will return that information. The 'LA_SUBR' define - will handle this for AIX V2 on the RT. - - Note: You will have to change the Makefile.AIX.2 to correctly - point to the locatons of the updated BIND source tree and - the location of the 'newdb' tree and library location. - You will also have to change the Makefile.AIX.2 to know - about the location of the 'getloadavg' routine if you use - the LA_SUBR define. - - - Manual pages will format correctly if given the mandoc macros - and used with nroff. I have not tried groff. - -RISC/os - RISC/os from MIPS is a merged AT&T/Berkeley system. When you - compile on that platform you will get duplicate definitions - on many files. You can ignore these. - -System V Release 4 Based Systems - There is a single Makefile that is intended for all SVR4-based - systems (called Makefile.SVR4). It defines __svr4__, which is - predefined by some compilers. If your compiler already defines - this compile variable, you can delete the definition from the - Makefile. - - It's been tested on Dell Issue 2.2. - -DELL SVR4 - Date: Mon, 06 Dec 1993 10:42:29 EST - From: "Kimmo Suominen" - Message-ID: <2d0352f9.lento29@lento29.UUCP> - To: eric@cs.berkeley.edu - Cc: sendmail@cs.berkeley.edu - Subject: Notes for DELL SVR4 - - Eric, - - Here are some notes for compiling Sendmail 8.6.4 on DELL SVR4. I ran - across these things when helping out some people who contacted me by - e-mail. - - 1) Use gcc 2.4.5 (or later?). Dell distributes gcc 2.1 with their - Issue 2.2 Unix. It is too old, and gives you problems with - clock.c, because sigset_t won't get defined in . - This is due to a problematic protection rule in there, and is - fixed with gcc 2.4.5. - - 2) If you don't use the new Berkeley DB (-DNEWDB), then you need - to add "-lc -lucb" to the libraries to link with. This is because - the -ldbm distributed by Dell needs the bcopy, bcmp and bzero - functions. It is important that you specify both libraries in - the given order to be sure you only get the BSTRING functions - from the UCB library (and not the signal routines etc.). - - 3) Don't leave out "-lelf" even if compiling with "-lc -lucb". - The UCB library also has another copy of the nlist routines, - but we do want the ones from "-lelf". - - If anyone needs a compiled gcc 2.4.5 and/or a ported DB library, they - can use anonymous ftp to fetch them from lut.fi in the /kim directory. - They are copies of what I use on grendel.lut.fi, and offering them - does not imply that I would also support them. I have sent the DB - port for SVR4 back to Keith Bostic for inclusion in the official - distribution, but I haven't heard anything from him as of today. - - - gcc-2.4.5-svr4.tar.gz (gcc 2.4.5 and the corresponding libg++) - - db-1.72.tar.gz (with source, objects and a installed copy) - - Cheers - + Kim - -- - * Kimmo.Suominen@lut.fi * SysVr4 enthusiast at GRENDEL.LUT.FI * - * KIM@FINFILES.BITNET * Postmaster and Hostmaster at LUT.FI * - * + 358 200 865 718 * Unix area moderator at NIC.FUNET.FI * - -ConvexOS 10.1 and below - In order to use the name server, you must create the file - /etc/use_nameserver. If this file does not exist, the call - to res_init() will fail and you will have absolutely no - access to DNS, including MX records. - -Amdahl UTS 2.1.5 - In order to get UTS to work, you will have to port BIND 4.9. - The vendor's BIND is reported to be ``totally inadequate.'' - See sendmail/contrib/AmdahlUTS.patch for the patches necessary - to get BIND 4.9 compiled for UTS. - -UnixWare 2.0 - According to Alexander Kolbasov , - the m4 on UnixWare 2.0 (still in Beta) will core dump on the - config files. GNU m4 and the m4 from UnixWare 1.x both work. - -UNICOS 8.0.3.4 - Some people have reported that the -O flag on UNICOS can cause - problems. You may want to turn this off if you have problems - running sendmail. Reported by Jerry G. DeLapp . - -Non-DNS based sites - This version of sendmail always tries to connect to the Domain - Name System (DNS) to resolve names, regardless of the setting - of the `I' option. On most systems that are not running DNS, - this will fail quickly and sendmail will continue, but on some - systems it has a long timeout. If you have this problem, you - will have to recompile without NAMED_BIND. Some people have - claimed that they have successfully used "OI+USEVC" to force - sendmail to use a virtual circuit -- this will always time out - quickly, but also tells sendmail that a failed connection - should requeue the message (probably not what you intended). - A future release of sendmail will correct this problem. - -Both NEWDB and NDBM - If you use both -DNDBM and -DNEWDB, you must delete the module - ndbm.o from libdb.a and delete the file "ndbm.h" from the files - that get installed (that is, use the OLD ndbm.h, not the new - ndbm.h). This compatibility module maps ndbm calls into DB - calls, and breaks things rather badly. - -GNU getopt - I'm told that GNU getopt has a problem in that it gets confused - by the double call. Use the version in conf.c instead. - -BIND 4.9.2 and Ultrix - If you are running on Ultrix, be sure you read conf/Info.Ultrix - in the BIND distribution very carefully -- there is information - in there that you need to know in order to avoid errors of the - form: - - /lib/libc.a(gethostent.o): sethostent: multiply defined - /lib/libc.a(gethostent.o): endhostent: multiply defined - /lib/libc.a(gethostent.o): gethostbyname: multiply defined - /lib/libc.a(gethostent.o): gethostbyaddr: multiply defined - - during the link stage. - -strtoul - Some compilers (notably gcc) claim to be ANSI C but do not - include the ANSI-required routine "strtoul". If your compiler - has this problem, you will get an error in srvrsmtp.c on the - code: - - # ifdef defined(__STDC__) && !defined(BROKEN_ANSI_LIBRARY) - e->e_msgsize = strtoul(vp, (char **) NULL, 10); - # else - e->e_msgsize = strtol(vp, (char **) NULL, 10); - # endif - - You can use -DBROKEN_ANSI_LIBRARY to get around this problem. - -Listproc 6.0c - Date: 23 Sep 1995 23:56:07 GMT - Message-ID: <95925101334.~INN-AUMa00187.comp-news@dl.ac.uk> - From: alansz@mellers1.psych.berkeley.edu (Alan Schwartz) - Subject: Listproc 6.0c + Sendmail 8.7 [Helpful hint] - - Just upgraded to sendmail 8.7, and discovered that listproc 6.0c - breaks, because it, by default, sends a blank "HELO" rather than - a "HELO hostname" when using the 'system' or 'telnet' mailmethod. - - The fix is to include -DZMAILER in the compilation, which will - cause it to use "HELO hostname" (which Z-mail apparently requires - as well. :) - -LDAP - LDAP was provided by Booker Bense of - Stanford University. From Booker: - - - The patch attached to this message implements an Ldap map class. - Currently we are using this at stanford to support campus-wide - email addressing. This project is discussed at - http://www-leland.stanford.edu/group/networking/project/sunetid.html - - - Currently we are using the ldap map as follows: - - Kluser ldapx - -h"localhost borax.stanford.edu borate.stanford.edu boron.stanford.edu" - -k"mailacceptinggeneralid=%s" -v maildrop - - and in Rule set S5 - - # Now attempt to lookup in luser (ldap map) - R< $L > $+ $: < $L > $( luser $1 $) - R< $* > $+ @ $+ $: < $3 > $2 Rewrite if forward - - - The map definition supports most of the standard Map args plus most - of the command line options of ldapsearch. The software is currently - limited to only accepting the first entry returned. It expects that - the map defines an ldap filter that returns at most 1 valid entry. - It requires the ldap and lber libraries from the Umich Ldap3.2 - release. - - I've tested the software on Solaris.2.4 with gcc and on NeXTStep3.2 - and it runs without problems. If you have any questions, please - send them along. - -TCP Wrappers - If you are using -DTCPWRAPPERS to get TCP Wrappers support you will - also need to install libwrap.a and modify the Makefile to include - -lwrap in the LIBS line (make sure that INCDIRS and LIBDIRS point - to where the tcpd.h and libwrap.a can be found). - - TCP Wrappers is available on ftp.win.tue.nl in /pub/security; - grab tcp_wrappers_.tar.gz (where is the highest - numbered version). - - If you have alternate MX sites for your site, be sure that all of - your MX sites reject the same set of hosts. If not, a bad guy whom - you reject will connect to your site, fail, and move on to the next - MX site, which will accept the mail for you and forward it on to you. - - -+--------------+ -| MANUAL PAGES | -+--------------+ - -The manual pages have been written against the -mandoc macros -instead of the -man macros. The latest version of groff has them -included. You can also get a copy from FTP.UU.NET in directory -/systems/unix/bsd-sources/share/tmac. - - -+-----------------+ -| DEBUGGING HOOKS | -+-----------------+ - -As of 8.6.5, sendmail daemons will catch a SIGUSR1 signal and log -some debugging output (logged at LOG_DEBUG severity). The -information dumped is: - - * The value of the $j macro. - * A warning if $j is not in the set $=w. - * A list of the open file descriptors. - * The contents of the connection cache. - * If ruleset 89 is defined, it is evaluated and the results printed. - -This allows you to get information regarding the runtime state of the -daemon on the fly. This should not be done too frequently, since -the process of rewriting may lose memory which will not be recovered. -Also, ruleset 89 may call non-reentrant routines, so there is a small -non-zero probability that this will cause other problems. It is -really only for debugging serious problems. - -A typical formulation of ruleset 89 would be: - - R$* $@ $>0 some test address - - -+-----------------------------+ -| DESCRIPTION OF SOURCE FILES | -+-----------------------------+ - -The following list describes the files in this directory: - -Makefile The makefile used here; this version only works with - the new Berkeley make. -Makefile.dist A trimmed down version of the makefile that works with - the old make. -READ_ME This file. -TRACEFLAGS My own personal list of the trace flags -- not guaranteed - to be particularly up to date. -alias.c Does name aliasing in all forms. -arpadate.c A subroutine which creates ARPANET standard dates. -clock.c Routines to implement real-time oriented functions - in sendmail -- e.g., timeouts. -collect.c The routine that actually reads the mail into a temp - file.
