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 behaviour 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 wierd 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 is believed to be a bug in the Linux kernel. - -* 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 $h is the port number instead of the host name) the - connection caching code will break because it won't notice that - two messages addressed to different ports should use different - connections. - -* ESMTP SIZE underestimates the size of a message - - Sendmail makes no allowance for headers that it adds, nor does it - account for the SMTP on-the-wire \r\n expansion. It probably doesn't - allow for 8->7 bit MIME conversions either. - - -(Version 8.25, last updated 6/13/97) diff --git a/usr.sbin/sendmail/Makefile b/usr.sbin/sendmail/Makefile deleted file mode 100644 index cd281232216a..000000000000 --- a/usr.sbin/sendmail/Makefile +++ /dev/null @@ -1,55 +0,0 @@ -# @(#)Makefile 8.15 (Berkeley) 9/21/96 - -VER= XX -SUBDIR= src mail.local mailstats makemap praliases smrsh cf/cf -FTPDIR= mastodon:/disks/barad-dur/ftp/sendmail/. -DISTFILES=sendmail.${VER}.tar.Z sendmail.${VER}.tar.gz \ - RELEASE_NOTES FAQ KNOWNBUGS -FILES= Files.base Files.cf Files.misc Files.xdoc - -tar: sccs-check compile-world run-pax - -sccs-check: - sccs check - (cd src; sccs check) - (cd mail.local; sccs check) - (cd mailstats; sccs check) - (cd makemap; sccs check) - (cd praliases; sccs check) - (cd smrsh; sccs check) - (cd doc/op; sccs check) - (cd doc/intro; sccs check) - (cd doc/usenix; sccs check) - (cd cf; sccs check) - (cd cf/m4; sccs check) - (cd cf/mailer; sccs check) - (cd cf/feature; sccs check) - (cd cf/cf; sccs check) - (cd cf/ostype; sccs check) - (cd cf/domain; sccs check) - -compile-world: - (cd src; sh makesendmail) - (cd mail.local; ${MAKE}) - (cd mailstats; ${MAKE}) - (cd makemap; ${MAKE}) - (cd praliases; ${MAKE}) - (cd smrsh; ${MAKE}) - (cd doc; PRINTER=ps ${MAKE}) - (cd doc; chmod 444 op/op.ps intro/intro.ps usenix/usenix.ps) - (cd cf/cf; ${MAKE}) - -run-pax: Files.base Files.cf Files.misc Files.xdoc - chmod +x src/makesendmail - pax -w -x tar -L \ - -s ",cf/domain/unspecified-domain,sendmail-${VER}/cf/domain/berkeley-only,p" \ - -s ",^,sendmail-${VER}/," \ - -f sendmail.${VER}.tar \ - `cat ${FILES} | grep -v ^#` - gzip -c sendmail.${VER}.tar > sendmail.${VER}.tar.gz - compress sendmail.${VER}.tar - -ftp: sendmail.${VER}.tar.Z - rcp ${DISTFILES} ${FTPDIR} - -.include <bsd.subdir.mk> diff --git a/usr.sbin/sendmail/READ_ME b/usr.sbin/sendmail/READ_ME deleted file mode 100644 index 08b5affb04f9..000000000000 --- a/usr.sbin/sendmail/READ_ME +++ /dev/null @@ -1,326 +0,0 @@ -/*- - * @(#)READ_ME 8.32 (Berkeley) 7/6/97 - */ - - SENDMAIL RELEASE 8 - -This directory has the latest sendmail software from Berkeley.

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). 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.

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.

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. Suggested by - Bryan Costales of InfoBeat, Inc. - Display the proper Final-Recipient on DSN messages for non-SMTP - mailers. Problem noted by Kari E.

Fix from Chuck Lever of the University of Michigan. - Drop recipient address from 251 and 551 SMTP responses per RFC 821. - Problem noted by Kari E. Hurtta of the Finnish Meteorological - Institute. - Make sure non-rebuildable database maps are opened before the - rebuildable maps (i.e. alias files) in case the database maps - are needed for verifying the left hand side of the aliases. - Problem noted by Lloyd Parkes of Victoria University. - Make sure sender RFC822 source route addresses are alias expanded for - bounce messages. Problem noted by Juergen Georgi of - RUS University of Stuttgart. - Minor lint fixes. - Return a temporary error instead of a permanent error if an LDAP map - search returns an error. This will allow sequenced maps which - use other LDAP servers to be checked. Fix from Booker Bense - of Stanford University. - When automatically converting from quoted printable to 8bit text do - not pad bare linefeeds with a space. Problem noted by Theo - Nolte of the University of Technology Aachen, Germany. - Portability: - Non-standard C compilers may have had a problem compiling - conf.c due to a standard C external declaration of - setproctitle(). Problem noted by Ted Roberts of - Electronic Data Systems. - AUX: has a broken O_EXCL implementation.

Patch from Raymund Will of LST Software - GmbH. - Bogus incoming SMTP commands would reset the SMTP conversation. - Problem noted by Fredrik Jönsson of the Royal Institute - of Technology, Stockholm. - Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), - some environments could give "multiple definitions" for these - routines during compilation. If using TCP Wrappers, assume - that these routines are included as though they were in the - C library. 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 <sys/select.h>. 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 <memory.h> 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 <setjmp.h> 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. Suggested - by Harry Styron. - CONFIG: Improve sample anti-spam rulesets in cf/cf/knecht.mc. These - are the rulesets in use on sendmail.org. - MAKEMAP: give error on GDBM files. - MAIL.LOCAL: Make error messages a bit more explicit, for example, - telling more details on what actually changed when "file - changed after open". - CONTRIB: etrn.pl: Ignore comments in Fw files. Support multiple Fw - files. - CONTRIB: passwd-to-alias.pl: Handle 8 bit characters and '-'. - NEW FILES: - src/Makefiles/Makefile.OpenBSD - src/Makefiles/Makefile.RISCos.4_0 - test/t_exclopen.c - cf/ostype/sco-uw-2.1.m4 - DELETED FILES: - Makefile - -8.8.6/8.8.6 97/06/14 - ************************************************************* - * The extensive assistance of Gregory Neil Shapiro of WPI * - * in preparing this release is gratefully appreciated. * - * Sun Microsystems has also provided resources toward * - * continued sendmail development. * - ************************************************************* - SECURITY: A few systems allow an open with the O_EXCL|O_CREAT open - mode bits set to create a file that is a symbolic link that - points nowhere. 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 <addr>'") - 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 <miorelli@pweh.com>. - 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 <leshka@leshka.chuvashia.su> 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, <db.h> (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 <dubois@primate.wisc.edu>. - 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 <teddy@fukt.hk-r.se>. - 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 <paths.h> 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 - <bbense@networking.stanford.edu>; 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 <tegge@idt.ntnu.no> 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 - <bicknell@ufp.org>. - 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.

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 <anthony@cit.gu.edu.au>. - 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 <Vlado_Potisk@tempest.sk>. - 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. Fix from Michael Scott Shappe. - PRALIASES: add man page contributed by Keith Bostic of BSDI. - NEW FILES: - src/Makefiles/Makefile.AIX.2 - src/Makefiles/Makefile.IRIX.6.2 - src/Makefiles/Makefile.maxion - src/Makefiles/Makefile.NCR.MP-RAS.3.x - src/Makefiles/Makefile.SCO.5.x - src/Makefiles/Makefile.UXPDSV20 - mailstats/mailstats.8 - praliases/praliases.8 - cf/cf/generic-nextstep3.3.mc - cf/feature/genericstable.m4 - cf/feature/limited_masquerade.m4 - cf/feature/masquerade_entire_domain.m4 - cf/feature/virtusertable.m4 - cf/ostype/aix2.m4 - cf/ostype/altos.m4 - cf/ostype/maxion.m4 - cf/ostype/solaris2.ml.m4 - cf/ostype/uxpds.m4 - contrib/re-mqueue.pl - DELETED FILES: - src/Makefiles/Makefile.Solaris - contrib/xla/README - contrib/xla/xla.c - RENAMED FILES: - src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x - src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 - src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 - src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x - src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x - -8.7.6/8.7.3 96/09/17 - SECURITY: It is possible to force getpwuid to fail when writing the - queue file, causing sendmail to fall back to running programs - as the default user. 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: <host>: <user> set - sender to <addresss> 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 <bjart.kvarme@usit.uio.no>. - 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 - <frank@ansto.gov.au>. - 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. From Thomas.Tornblom@Hax.SE. - CONFIG: Minor glitch in S21 -- attachment of local domain name - didn't have trailing dot. From Jim Hickstein of Teradyne. - CONFIG: Fix best_mx_is_local feature to allow nested addresses such as - user%host@thishost. From Claude Scarpelli of Infobiogen - (France). - CONFIG: OSTYPE(hpux10) failed to define the location of the help file. - Pointed out by Hannu Martikka of Nokia Telecommunications. - CONFIG: Diagnose some inappropriate ordering in configuration files, - such as FEATURE(smrsh) listed after MAILER(local). 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 <jgm+@CMU.EDU>; - 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 <WOLF@CLEMSON.EDU> - 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 - <andre@curry.zfe.siemens.de>. - Support for Fujitsu/ICL UXP/DS (For the DS/90 Series) - from Diego R. Lopez <drlopez@cica.es>. - 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 "<LWSP>#@#<LWSP>", where <LWSP> - 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, - <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori - (romanized/less information) - <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= - =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= - (with MIME encoding, not human readable) - <motonori@cs.ritsumei.ac.jp> #@# ^[$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<envar>" will propogate - the named variable from the environment when sendmail - was invoked into any children it calls; "E<envar>=<value>" - 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 <MARINIER@emp.ewd.dreo.dnd.ca>. - 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 <cudcv@csv.warwick.ac.uk>. - 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 <mtr@ornl.gov>. 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 <mccarty@mpd.tandem.com>. - 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 <timr@crl.com>. - OSF/1 running on Intel Paragon from Jeff A. Earickson - <jeff@ssd.intel.com> of Intel Scalable Systems - Divison. - Amdahl UTS System V 2.1.5 (SVr3-based) from Janet Jackson - <janet@dialix.oz.au>. - 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. Rand of the University of North - Dakota, Scientific Computing Center. - Solaris 2.4 fixes from Sanjay Dani of Dani Communications. - ConvexOS 11.0 from Christophe Wolfhugel. - IRIX 4.0.5 from David Ashton-Reader of CADcentre. - ISC UNIX from J. J. Bailey. - HP-UX 9.xx on the 8xx series machines from Remy Giraud - of Meteo France. - HP-UX configuration from Tom Lane <tgl@sss.pgh.pa.us>. - IRIX 5.2 and 5.3 from Kari E. Hurtta. - FreeBSD 2.0 from Mike Hickey of Federal Data Corporation. - Sony NEWS-OS 4.2.1R and 6.0.3 from Motonori Nakamura. - Omron LUNA unios-b, mach from Motonori Nakamura. - NEC EWS-UX/V 4.2 from Motonori Nakamura. - NeXT 2.1 from Bryan Costales. - AUX patch thanks to Mike Erwin of Apple Computer. - HP-UX 10.0 from John Beck of Hewlett-Packard. - Ultrix: allow -DBROKEN_RES_SEARCH=0 if you are using a - non-DEC resolver. 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 <dwj@agw.bt.co.uk>. - 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 <sys/vfs.h>, - <sys/mount.h>, or <sys/statfs.h> 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 - <jmrm@eng.cam.ac.uk>. - 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:<foo>'' 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 $M overrides :mailname entries in the user - database! Problem noted by Paul Southworth. - CONFIG: Fix definition of Solaris help file location. From - Steve Cliffe <steve@gorgon.cs.uow.edu.au>. - CONFIG: Fix bug that broke news.group.USENET mappings. - CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, - and USENET_MAILER_MAX to tweak the maximum message - size for various mailers. - CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] - instead of assuming that it is "inews" for consistency - with other mailers. From Michael Corrigan of UC San Diego. - CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, - qualify the address in the SMTP envelope as user@{relay|hub} - instead of user@$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 - <besancon@excalibur.ens.fr>. - 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 Kimmo - Suominen. - Portability fixes: - Unicos from David L. Kensiski of Sterling Sofware. - DomainOS from Don Lewis of Silicon Systems. - GNU m4 1.0.3 from Karst Koymans of Utrecht University. - Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. - NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. - BSD/386 from Tony Sanders of BSDI. - Apollo from Eric Wassenaar. - DGUX from Doug Anderson. - Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. - NEW FILES: - src/Makefile.DomainOS - src/Makefile.PTX - src/Makefile.SunOS.5.1 - src/Makefile.SunOS.5.2 - src/Makefile.SunOS.5.x - src/mailq.1 - cf/ostype/domainos.m4 - doc/op/Makefile - doc/intro/Makefile - doc/usenix/Makefile - -8.6.5/8.6.5 94/01/13 - Security fix: /.forward could be owned by anyone (the test - to allow root to own any file was backwards). 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 <angle brackets> around - them in non-SMTP envelopes (SMTP envelopes already do - this properly). - Avoid weird headers on unbalanced punctuation of the form: - ``Joe User <user)'' -- this caused reference to the - null macro. Fix from Rick McCarty of IO.COM. - Fix a problem that caused an alias "user: user@local.host" to - not have the QNOTREMOTE bit set; this caused configs - to act as if FEATURE(notsticky) was defined even when - it was not. The effect of the problem was to make it - very hard to to set up satellite sites that had a few - local accounts, with everything else forwarded to a - corporate hub. Reported by Detlef Drewanz of the - University of Rostock and Mark Frost of NCD. - Change queuing to not call rulesets 3, {1 or 2}, 4 on header - addresses. This is more efficient (fewer name server - calls) and fixes certain unusual configurations, such - as those that have ruleset 4 do something that is - non-idempotent unless a mailer-specific ruleset did - something else. Problem reported by Brian J. Coan - of the Institute for Global Communications. - Fix the "obsolete argument" routine in main to better understand - new arguments. For example, if you used ``sendmail - -C config -v -q'' it would choke on the -q because - the -C would stop looking for old-format arguments. - Fix the code that was intended to allow two users to forward their - mail to the same program and have them appear unique. - Portability fixes for: - SCO UNIX from Murray Kucherawy. - SCO Open Server 3.2v4 from Philippe Brand. - System V Release 4 from Rick Ellis and others. - OSF/1 from Steve Campbell. - DG/UX from Ben Mesander of the USGS and Bryan Curnutt - of Stoner Associates. - Motorola SysV88 from Kevin Johnson of Motorola. - Solaris 2.3 from Casper H.S. Dik of the University - of Amsterdam and John Caruso of University - of Maryland. - FreeBSD from Ollivier Robert. - NetBSD from Adam Glass. - TitanOS from Kate Hedstrom of Rutgers University. - Irix from Bryan Curnutt. - Dynix from Jim Davis of the University of Arizona. - RISC/os. - Linux from John Kennedy of California State University - at Chico. - Solaris 2.x from Tony Boner of the U.S. Air Force. - NEXTSTEP 3.x from Vince DeMarco. - HP-UX from various people. NOTA BENE: the location - of the config file has moved to /usr/lib - to match the HP-UX version of sendmail. - CONFIG: Don't do any recipient rewriting on relay mailer; - since this is intended only for internal use, the - usual RFC 821/822/1123 rules can be relaxed. The - main point of this is to avoid munging (ugh) UUCP - addresses when relaying internally. - CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; - syntax addresses delivered via UUCP. Solution - provided by Peter Wemm. - CONFIG: fix thumb-fumble in default UUCP relaying in ruleset - zero; it caused double @ signs in addresses. From - Irving Reid of the University of Toronto. - CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 - from Markku Toijala of ICL Personal Systems Oy. - CONFIG: Add trailing "." on pseudo-domains for consistency; - this fixes a problem (noted by Al Whaley of Sunnyside) - that made it hard to recognize your own pseudodomain - names. - CONFIG: catch "@host" syntax errors (i.e., null local-parts) - rather than letting them get "local configuration - error"s. Problem noted by John Gardiner Myers. - CONFIG: add uucp-uudom mailer variant, based on code posted - by Spider Boardman <spider@Orb.Nashua.NH.US>; 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 - <kim@grendel.lut.fi>). - 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 <list:;> 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 <karl@borg.demon.co.uk>), 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 ``<foo> <bar>'', auto-quote the first - ``<foo>'' part, giving ``"<foo>" <bar>''. 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<HOST> -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 - <drich@sandman.lerc.nasa.gov>. - Solaris 2 compatibility changes. Provided by Bob Cunningham - <bob@kahala.soest.hawaii.edu>, John Oleynick - <juo@klinzhai.rutgers.edu> - 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 "<a" is presented - to an SMTP server. It doesn't seem to occur on all - machines. From Motonori Nakamura. - Default IDENTPROTO off for Ultrix and HPUX, which apparently have - the interesting "feature" that when they receive a "Host - unreachable" message they closes all open connections to - that host. However, some firewall gateways send this message - if you try to connect to an unauthorized port, such as the - IDENT port (113). Thus, no email can be received from such - hosts. There is some evidence that versions of Ultrix before - 4.3 do not have this problem. Thanks to Tom Ivar Helbekkmo - for pointing out this behaviour to me and to Michael Corrigan - of U.C. San Diego for informing me about the HPUX problem. - Allow IPC mailers to return a colon-separated list of hosts in the - $@ clause; these are searched in order as though they were - MX records. - When sending an error report, print the list of addresses tagged - as bad. Requested by Allan E Johannesen of WPI. - Change map function calls to return a status code. This gets - passed back as the result of rewrite. Parseaddr marks - the address as a QUEUEUP address if the return code is - EX_TEMPFAIL. All this to queue properly if the name - server is down. This code is not well tested. This code - changes the interface to map lookup functions (a fifth - parameter, int *statp, is added). Feature requested by - Dan Oscarsson. - Don't delete quotes (in the dequote map) if there are spaces in - the string, since this would cause them to be replaced by - the SpaceSub character. - Accept BODY=8BITMIME on SMTP MAIL command. This isn't advertised - because the 8BIT to 7BIT translation doesn't exist yet. - This does add a "bodytype" field to both envelope and - queue file and a -B command line flag to pass the type in - during direct invocations. - Discard return error messages only on responses to responses to - responses, not on responses to responses. That is, the - algorithm is to try return to sender, then return to - postmaster, then discard. Previously it discarded - immediately if the return to sender pass failed. - CONFIG: back out change to hide unqualified hostnames behind %-hack. - This screws up local aliases and .forward files. - CONFIG: add FEATURE(nocanonify) to turn off calls to $[ ... $]; - some sites only handle completely canonified names. - Requested by John Gardiner Myers of CMU. - CONFIG: some UUCP code was still included even if FEATURE(nouucp) - was specified. - -6.52/6.24 93/04/10 - Clean up some minor glitches on error return messages pointed out - by Motonori Nakamura of Kyoto University. - Fix reply() to not reset SmtpReplyBuffer on fatal errors; this - was supposed to reset SmtpMsg Buffer. This makes the - client side code virtually useless. Reported by Allan - E Johannesen of WPI and Phil Brandenberger of Swarthmore. - Better debug messages if fuzzy is disabled, suggested by Allan - E Johannesen of WPI. - Offset SmtpReplyBuffer by four in usersmtp when checking for - loopback. From Eric Wassenaar. - Don't set $s until after runinchild in srvrsmtp -- otherwise - it gets cleared. From Eric Wassenaar. - Implement IDA-style $&x for deferred macro expansion. - More POSIX compatibility. - CONFIG: Hide unqualified hostnames behind %-hack using $s as the - actual sender. This is only done if $r is non-null, that - is, if this is not locally submitted mail. - CONFIG: Add FEATURE(bitdomain) allowing mapping of BITNET host - names to internet domains. A program contributed by - John Gardiner Myers of CMU to create the maps is included - in the contrib directory (in the "misc" tar file). - CONFIG: Add FEATURE(uucpdomain) for a similar mapping for UUCP - hosts. There is currently no tool to create this map. - -6.51/6.23 93/04/04 - Add D= mailer flag to specify a path of possible working directories - in which to execute the mailer. This is intended for the - prog mailer; some shells can get upset if they don't have - access to the current directory. - Add RFC 1413 (IDENT) protocol support. This is only very loosely - tested. This adds a $_ macro to be the authenticated - info (in ``user@domain [address]'' form) and debug flag - 9 to trace the protocol. - Check for loopbacks in usersmtp instead of srvrsmtp -- there is no - reason for a local agent to not be talking to the localhost - (although the inverse is not true). - Add a few hooks for automated map rebuilding. This is certainly - not done yet. - CONFIG: Have prog mailer specify a path of ``D=$z:/'' -- that is, - user's home directory then the root. - CONFIG: Log RFC 1413 identification in Received: line. - -6.50/6.22 93/04/01 - Fixes to requeueing code to make it compute priority, nrcpts, - and the like properly. - -6.49/6.22 93/04/01 - Diagnose incorrect privacy flags. Suggested by Bryan Costales - of ICSI. - Some ANSI C fixes. - Arrange to quote backslashes as well as other special characters - in the phrase part of a route-addr. - Some fixes to FallBackMX code suggested by Motonori Nakamura of - Kyoto University. - More vigorous zeroing of CurHostAddr to avoid logging of bogus - host addresses when you are actually just printing - information from the MCI structure; problem noted by - Michael Corrigan of U.C. San Diego. - Don't ignore rest of queue if any job is not runnable. This can - also cause an incorrect job to be lost. Fix from - Eric Wassenaar. - Always respond "quickly" to RCPT command; do alias expansion and - the like later. This also means that mail for lists that - have errors will be acccepted, and an error sent back - later. This is done by instantiating the queue file - and then immediately running and requeueing it. - -6.48/6.22 93/03/30 - Fix incorrect diagnosis of infinite loop in ruleset. Problem noted - by several people. - Improve information printed when infinite loops are discovered. - Zero CurHostAddr to fix erroneous internet addresses in log when no - addresses can be bound. Pointed out by Motonori Nakamura - of Kyoto University. - "Probe" SMTP connections using RSET instead of NOOP "just in case". - Suggested by John Gardiner Myers of CMU. - Don't warn about -f if you are setting sender to yourself. - -6.47/6.22 93/03/29 - Fix incompatible call to endmailer in smtpquit which causes core - dumps. Noted by Allan E Johannesen of WPI. - HPUX portability changes from Michael J. Corrigan of UC San Diego. - Require MAIL before RCPT command in srvrsmtp.c. This had been - intentional from the 821 draft days when the order wasn't - clear, but is silly now. - Fix bug in nis_magic routine that was initializing parameters - incorrectly. Fix from Takahiro Kanbe of Fuji Xerox - Information Systems Co., Ltd. - Change default for PrivacyFlags in conf.c to 0 -- since it always - "or"s in new values, there was no way to turn off the - AuthWarning stuff. - Add O option to set SMTP daemon options. - Add V option to set fallback MX host. This always sorts at lower - priority than anything it gets from the name server. It - should only be used for environments with very bad network - connectivity. Requested by several people. - Log sending info. It's not clear this is a good idea. - CONFIG: fix typo in mailertable code. Noted by Phil Brandenberger - of Swarthmore. - CONFIG: add confDAEMON_OPTIONS and confFALLBACK_MX to set options - O and V, respectively. - -6.46/6.21 93/03/26 - Fix botch in server SMTP that broke transactions that did not - use HELO first (like MH). Fix from Michael Corrigan - of U.C. San Diego. - Fall back to other MX records if there is an error anywhere - in delivery (actually on MAIL or DATA -- RCPT is harder). - Suggested by John Gardiner Myers and Motonori Nakamura. - Revert to non-prototypes -- it turns out that our ANSI C - compiler is more forgiving than most others about - mixing prototyped extern declarations with non-prototyped - function definitions. - Fix a problem with multi-word class matching pointed out by - Neil Rickert. Given: - CX b a.b.c - R$+ $=X $+ $: $1 < $2 > $3 - the input "user@a.b.c" failed instead of being properly - rewritten as "user@a.<b>.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 <unistd.h> 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 <sys/mount.h>. - 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).

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<domain>") 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 <null>, "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<name1> <name2> ..." 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 <address>'' 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 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.

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.

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.

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.

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.

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\ \ \ \ <muir@idiom.com> 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 <eric@sendmail.org>; 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 <eric@sendmail.org> -cc: marc@xfree86.org -Subject: Updated mailprio_0_93.shar -From: Tony Sanders <sanders@earth.com> -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<space>'' -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 <email address>'' 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; -the -.b $: -is necessary to avoid an infinite loop. -.pp -Substitution occurs in the order described, -that is, -parameters from the LHS are substituted, -hostnames are canonicalized, -.q subroutines -are called, -and finally -.b $# , -.b $@ , -and -.b $: -are processed. -.sh 3 "Semantics of rewriting rule sets" -.pp -There are five rewriting sets -that have specific semantics. -Four of these are related as depicted by

-Ruleset three -should turn the address into -.q "canonical form." -This form should have the basic syntax: -.(b -local-part@host-domain-spec -.)b -Ruleset three -is applied by -.i sendmail -before doing anything with any address. -.pp -If no -.q @ -sign is specified, -then the -host-domain-spec -.i may -be appended (box -.q D -in Figure 1) -from the -sender address -(if the -.b C -flag is set in the mailer definition -corresponding to the -.i sending -mailer). -.pp -Ruleset zero -is applied after ruleset three -to addresses that are going to actually specify recipients. -It must resolve to a -.i "{mailer, host, user}" -triple. -The -.i mailer -must be defined in the mailer definitions -from the configuration file. -The -.i host -is defined into the -.b $h -macro -for use in the argv expansion of the specified mailer. -.pp -Rulesets one and two -are applied to all sender and recipient addresses respectively. -They are applied before any specification -in the mailer definition. -They must never resolve. -.pp -Ruleset four is applied to all addresses -in the message. -It is typically used -to translate internal to external form. -.pp -In addition, -ruleset 5 is applied to all local addresses -(specifically, those that resolve to a mailer with the `F=5' -flag set) -that do not have aliases. -This allows a last minute hook for local names. -.sh 3 "Ruleset hooks" -.pp -A few extra rulesets are defined as -.q hooks -that can be defined to get special features. -They are all named rulesets. -The -.q check_* -forms all give accept/reject status; -falling off the end or returning normally is an accept, -and resolving to $#error -is a reject. -.sh 4 "check_relay" -.pp -The -.i check_relay -ruleset is called after a connection is accepted. -It is passed -.(b -client.host.name $| client.host.address -.)b -where -.b $| -is a metacharacter separating the two parts. -This ruleset can reject connections from various locations. -.sh 4 "check_mail" -.pp -The -.i check_mail -ruleset is passed the user name parameter of the -.sm "SMTP MAIL" -command. -It can accept or reject the address. -.sh 4 "check_rcpt" -.pp -The -.i check_rcpt -ruleset is passed the user name parameter of the -.sm "SMTP RCPT" -command. -It can accept or reject the address. -.sh 4 "check_compat" -.pp -The -.i check_compat -ruleset is passed -.(b -sender-address $| recipient-address -.)b -where -.b $| -is a metacharacter separating the addresses. -It can accept or reject mail transfer between these two addresses -much like the -.i checkcompat() -function. -.sh 3 "IPC mailers" -.pp -Some special processing occurs -if the ruleset zero resolves to an IPC mailer -(that is, a mailer that has -.q [IPC] -listed as the Path in the -.b M -configuration line. -The host name passed after -.q $@ -has MX expansion performed; -this looks the name up in DNS to find alternate delivery sites. -.pp -The host name can also be provided as a dotted quad in square brackets; -for example: -.(b -[128.32.149.78] -.)b -This causes direct conversion of the numeric value -to a TCP/IP host address. -.pp -The host name passed in after the -.q $@ -may also be a colon-separated list of hosts. -Each is separately MX expanded and the results are concatenated -to make (essentially) one long MX list. -The intent here is to create -.q fake -MX records that are not published in DNS -for private internal networks. -.pp -As a final special case, the host name can be passed in -as a text string -in square brackets: -.(b -[ucbvax.berkeley.edu] -.)b -This form avoids the MX mapping. -.b N.B.: -.i -This is intended only for situations where you have a network firewall -or other host that will do special processing for all your mail, -so that your MX record points to a gateway machine; -this machine could then do direct delivery to machines -within your local domain. -Use of this feature directly violates RFC 1123 section 5.3.5: -it should not be used lightly. -.r -.sh 2 "D \*- Define Macro" -.pp -Macros are named with a single character -or with a word in {braces}. -Single character names may be selected from the entire ASCII set, -but user-defined macros -should be selected from the set of upper case letters only. -Lower case letters -and special symbols -are used internally. -Long names beginning with a lower case letter or a punctuation character -are reserved for use by sendmail, -so user-defined long macro names should begin with an upper case letter. -.pp -The syntax for macro definitions is: -.(b F -.b D \c -.i x\|val -.)b -where -.i x -is the name of the macro -(which may be a single character -or a word in braces) -and -.i val -is the value it should have. -There should be no spaces given -that do not actually belong in the macro value. -.pp -Macros are interpolated -using the construct -.b $ \c -.i x , -where -.i x -is the name of the macro to be interpolated. -This interpolation is done when the configuration file is read, -except in -.b M -lines. -The special construct -.b $& \c -.i x -can be used in -.b R -lines to get deferred interpolation. -.pp -Conditionals can be specified using the syntax: -.(b -$?x text1 $| text2 $. -.)b -This interpolates -.i text1 -if the macro -.b $x -is set, -and -.i text2 -otherwise. -The -.q else -(\c -.b $| ) -clause may be omitted. -.pp -Lower case macro names are reserved to have -special semantics, -used to pass information in or out of -.i sendmail , -and special characters are reserved to -provide conditionals, etc. -Upper case names -(that is, -.b $A -through -.b $Z ) -are specifically reserved for configuration file authors. -.pp -The following macros are defined and/or used internally by -.i sendmail -for interpolation into argv's for mailers -or for other contexts. -The ones marked \(dg are information passed into sendmail\**, -.(f -\**As of version 8.6, -all of these macros have reasonable defaults. -Previous versions required that they be defined. -.)f -the ones marked \(dd are information passed both in and out of sendmail, -and the unmarked macros are passed out of sendmail -but are not otherwise used internally. -These macros are: -.nr ii 5n -.ip $a -The origination date in RFC 822 format. -This is extracted from the Date: line. -.ip $b -The current date in RFC 822 format. -.ip $c -The hop count. -This is a count of the number of Received: lines -plus the value of the -.b \-h -command line flag. -.ip $d -The current date in UNIX (ctime) format. -.ip $e\(dg -(Obsolete; use SmtpGreetingMessage option instead.) -The SMTP entry message. -This is printed out when SMTP starts up. -The first word must be the -.b $j -macro as specified by RFC821. -Defaults to -.q "$j Sendmail $v ready at $b" . -Commonly redefined to include the configuration version number, e.g., -.q "$j Sendmail $v/$Z ready at $b" -.ip $f -The envelope sender (from) address. -.ip $g -The sender address relative to the recipient. -For example, if -.b $f -is -.q foo , -.b $g -will be -.q host!foo , -.q foo@host.domain , -or whatever is appropriate for the receiving mailer. -.ip $h -The recipient host. -This is set in ruleset 0 from the $# field of a parsed address. -.ip $i -The queue id, -e.g., -.q HAA12345 . -.ip $j\(dd -The \*(lqofficial\*(rq domain name for this site. -This is fully qualified if the full qualification can be found. -It -.i must -be redefined

MAILER-DAEMON . -.ip $o\(dg -(Obsolete: use OperatorChars option instead.) -The set of \*(lqoperators\*(rq in addresses. -A list of characters -which will be considered tokens -and which will separate tokens -when doing parsing. -For example, if -.q @ -were in the -.b $o -macro, then the input -.q a@b -would be scanned as three tokens: -.q a, -.q @, -and -.q b. -Defaults to -.q ".:@[]" , -which is the minimum set necessary to do RFC 822 parsing; -a richer set of operators is -.q ".:%@!/[]" , -which adds support for UUCP, the %-hack, and X.400 addresses. -.ip $p -Sendmail's process id. -.ip $q\(dg -Default format of sender address. -The -.b $q -macro specifies how an address should appear in a message -when it is defaulted. -Defaults to -.q "<$g>" . -It is commonly redefined to be -.q

-Defined in the SMTP server only. -.ip ${client_name} -The host name of the SMTP client. -Defined in the SMTP server only. -.ip ${client_port} -The port number of the SMTP client. -Defined in the SMTP server only. -.ip ${envid} -The envelope id passed to sendmail as part of the envelope. -.ip ${opMode} -The current operation mode (from the -.b \-b -flag). -.pp -There are three types of dates that can be used. -The -.b $a -and -.b $b -macros are in RFC 822 format; -.b $a -is the time as extracted from the -.q Date: -line of the message -(if there was one), -and -.b $b -is the current date and time -(used for postmarks). -If no -.q Date: -line is found in the incoming message, -.b $a -is set to the current time also. -The -.b $d -macro is equivalent to the -.b $b -macro in UNIX -(ctime) -format. -.pp -The macros -.b $w , -.b $j , -and -.b $m -are set to the identity of this host. -.i Sendmail -tries to find the fully qualified name of the host -if at all possible; -it does this by calling -.i gethostname (2) -to get the current hostname -and then passing that to -.i gethostbyname (3) -which is supposed to return the canonical version of that host name.\** -.(f -\**For example, on some systems -.i gethostname -might return -.q foo -which would be mapped to -.q foo.bar.com -by -.i gethostbyname . -.)f -Assuming this is successful, -.b $j -is set to the fully qualified name -and -.b $m -is set to the domain part of the name -(everything after the first dot). -The -.b $w -macro is set to the first word -(everything before the first dot) -if you have a level 5 or higher configuration file; -otherwise, it is set to the same value as -.b $j . -If the canonification is not successful, -it is imperative that the config file set -.b $j -to the fully qualified domain name\**. -.(f -\**Older versions of sendmail didn't pre-define -.b $j -at all, so up until 8.6, -config files -.i always -had to define -.b $j . -.)f -.pp -The -.b $f -macro is the id of the sender -as originally determined; -when mailing to a specific host -the -.b $g -macro is set to the address of the sender -.ul -relative to the recipient. -For example, -if I send to -.q bollard@matisse.CS.Berkeley.EDU -from the machine -.q vangogh.CS.Berkeley.EDU -the -.b $f -macro will be -.q eric -and the -.b $g -macro will be -.q eric@vangogh.CS.Berkeley.EDU. -.pp -The -.b $x -macro is set to the full name of the sender. -This can be determined in several ways. -It can be passed as flag to -.i sendmail . -It can be defined in the -.sm NAME -environment variable. -The third choice is the value of the -.q Full-Name: -line in the header if it exists, -and the fourth choice is the comment field -of a -.q From: -line. -If all of these fail, -and if the message is being originated locally, -the full name is looked up in the -.i /etc/passwd -file. -.pp -When sending, -the -.b $h , -.b $u , -and -.b $z -macros get set to the host, user, and home directory -(if local) -of the recipient. -The first two are set from the -.b $@ -and -.b $: -part of the rewriting rules, respectively. -.pp -The -.b $p -and -.b $t -macros are used to create unique strings -(e.g., for the -.q Message-Id: -field). -The -.b $i -macro is set to the queue id on this host; -if put into the timestamp line -it can be extremely useful for tracking messages. -The -.b $v -macro is set to be the version number of -.i sendmail ; -this is normally put in timestamps -and has been proven extremely useful for debugging. -.pp -The -.b $c -field is set to the -.q "hop count," -i.e., the number of times this message has been processed. -This can be determined -by the -.b \-h -flag on the command line -or by counting the timestamps in the message. -.pp -The -.b $r -and -.b $s -fields are set to the protocol used to communicate with -.i sendmail -and the sending hostname. -They can be set together using the -.b \-p -command line flag or separately using the -.b \-M -or -.b \-oM -flags. -.pp -The -.b $_ -is set to a validated sender host name. -If the sender is running an RFC 1413 compliant IDENT server -and the receiver has the IDENT protocol turned on, -it will include the user name on that host. -.pp -The -.b ${client_name} , -.b ${client_addr} , -and -.b ${client_port} -macros -are set to the name, address, and port number of the SMTP client -who is invoking -.i sendmail -as a server. -These can be used in the -.i check_* -rulesets (using the -.b $& -deferred evaluation form, of course!). -.sh 2 "C and F \*- Define Classes" -.pp -Classes of phrases may be defined -to match on the left hand side of rewriting rules, -where a -.q phrase -is a sequence of characters that do not contain space characters. -For example -a class of all local names for this site -might be created -so that attempts to send to oneself -can be eliminated. -These can either be defined directly in the configuration file -or read in from another file. -Classes are named as a single letter or

-Flags marked with \(dd -apply to the mailers for the sender address -rather than the usual recipient mailers. -.nr ii 4n -.ip a -Run Extended SMTP (ESMTP) protocol (defined in RFCs 1651, 1652, and 1653). -This flag defaults on if the SMTP greeting message includes the word -.q ESMTP . -.ip A -Look up the user part of the address in the alias database. -Normally this is only set for local mailers. -.ip b -Force a blank line on the end of a message. -This is intended to work around some stupid versions of -/bin/mail -that require a blank line, but do not provide it themselves. -It would not normally be used on network mail. -.ip c -Do not include comments in addresses. -This should only be used if you have to work around -a remote mailer that gets confused by comments. -This strips addresses of the form -.q "Phrase <address>" -or -.q "address (Comment)" -down to just -.q address . -.ip C\(dd -If mail is -.i received -from a mailer with this flag set, -any addresses in the header that do not have an at sign -(\c -.q @ ) -after being rewritten by ruleset three -will have the -.q @domain -clause from the sender envelope address -tacked on. -This allows mail with headers of the form: -.(b -From: usera@hosta -To: userb@hostb, userc -.)b -to be rewritten as: -.(b -From: usera@hosta -To: userb@hostb, userc@hosta -.)b -automatically. -However, it doesn't really work reliably. -.ip d -Do not include angle brackets around route-address syntax addresses. -This is useful on mailers that are going to pass addresses to a shell -that might interpret angle brackets as I/O redirection. -.ip D\(dg -This mailer wants a -.q Date: -header line. -.ip e -This mailer is expensive to connect to, -so try to avoid connecting normally; -any necessary connection will occur during a queue run. -.ip E -Escape lines beginning with -.q From -in the message with a `>' sign. -.ip f -The mailer wants a -.b \-f -.i from -flag, -but only if this is a network forward operation -(i.e., -the mailer will give an error -if the executing user -does not have special permissions). -.ip F\(dg -This mailer wants a -.q From: -header line. -.ip g -Normally, -.i sendmail -sends internally generated email (e.g., error messages) -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

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 UNIX-style -.q From -line on the front of the message. -.ip o -Always run as the owner of the recipient mailbox. -Normally -.i sendmail -runs as the sender for locally generated mail -or as -.q daemon -(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 <host>" -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 dot prepended -(to be stripped at the other end). -This insures that lines in the message containing a dot -will not terminate the message prematurely. -.ip 0 -Don't look up MX records for hosts sent 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. -.ip | -Check addresses to see if they begin with a `|'; -if they do, convert them to the -.q prog -mailer. -.ip / -Check addresses to see if they begin with a `/'; -if they do, convert them to the -.q *file* -mailer. -.ip @ -Look up addresses in the user database. -.pp -Configuration files prior to level 6 -assume the `A', `w', `5', `:', `|', `/', and `@' options -on the mailer named -.q local . -.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 , -.q *file* , -and -.q *include* -may be defined to tune the delivery of messages to programs, -files, -and :include: lists respectively. -They default to: -.(b -Mprog, P=/bin/sh, F=lsD, A=sh \-c $u -M*file*, P=/dev/null, F=lsDFMPEu, A=FILE -M*include*, P=/dev/null, F=su, A=INCLUDE -.)b -.pp -The Sender and Recipient rewriting sets -may either be a simple ruleset id -or may be two ids separated by a slash; -if so, the first rewriting set is applied to envelope -addresses -and the second is applied to headers. -.pp -The Directory -is actually a colon-separated path of directories to try. -For example, the definition -.q D=$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 representable as single characters -for back compatibility. -The syntax of this line is: -.(b F -.b O \0 -.i option \c -.b = \c -.i value -.)b -This sets option -.i option -to be -.i value . -Note 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 the old, one character names in brackets) are: -.nr ii 1i -.ip "AliasFile=\fIspec, spec, ...\fP" -[A] -Specify possible alias file(s). -Each -.i spec -should be in the format -``\c -.i class \c -.b : -.i file '' -where -.i class \c -.b : -is optional and defaults to ``implicit''. -Depending on how -.i sendmail -is compiled, valid classes are -.q implicit -(search through a compiled-in list of alias file types, -for back compatibility), -.q hash -(if -.sm NEWDB -is specified), -.q dbm -(if -.sm NDBM -is specified), -.q stab -(internal symbol table \*- not normally used -unless you have no other database lookup), -or -.q nis -(if -.sm NIS -is specified). -If a list of -.i spec s -are provided, -.i sendmail -searches them in order. -.ip AliasWait=\fItimeout\fP -[a] -If set, -wait up to -.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 system crashes during delivery to a large list, -this prevents retransmission to any but the last -.I N -recipients. -.ip ClassFactor=\fIfact\fP -[z] -The indicated -.i fact or -is multiplied by the 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 limits). -.ip DaemonPortOptions=\fIoptions\fP -[O] -Set server SMTP options. -The options are -.i key=value -pairs. -Known keys are: -.(b -.ta 1i -Port Name/number of listening port (defaults to "smtp") -Addr Address mask (defaults INADDR_ANY) -Family Address family (defaults to INET) -Listen Size of listen queue (defaults to 10) -SndBufSize Size of TCP send buffer -RcvBufSize Size of TCP 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 given as a symbolic user name.\** -.(f -\**The old -.b g -option has been combined into the -.b DefaultUser -option. -.)f -.ip DeliveryMode=\fIx\fP -[d] -Deliver in mode -.i x . -Legal modes are: -.(b -.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 a non-8BITMIME mailer. -The possible -.i action s -are: -.(b -.\" r Reject

with a slash, -it is assumed to be the pathname of a file -containing a message (this is the recommended setting). -Otherwise, it is a literal message. -The error file might contain the name, email address, and/or phone number -of a local postmaster who could provide assistance -in to end users. -If the option is missing or null, -or if it names a file which does not exist or which is not readable, -no message is printed. -.ip ErrorMode=\fIx\fP -[e] -Dispose of errors using mode -.i x . -The values for -.i x -are: -.(b -p Print error messages (default) -q No messages, just give exit

the queue in a separate process. -Use this option if you are short of memory, -since the default tends to consume considerable amounts of memory -while the queue is being processed. -.ip ForwardPath=\fIpath\fP -[J] -Set the path for searching for users' .forward files. -The default is -.q $z/.forward . -Some sites that use the automounter may prefer to change this to -.q /var/forward/$u -to search a file with the same name as the user in a system directory. -It can also be set to a sequence of paths separated by colons; -.i sendmail -stops at the first file it can successfully and safely open. -For example, -.q /var/forward/$u:$z/.forward -will search first in /var/forward/\c -.i username -and then in -.i ~username /.forward -(but only if the first file does not exist). -.ip HelpFile=\fIfile\fP -[H] -Specify the help file -for SMTP. -.ip HoldExpensive -[c] -If an outgoing mailer is marked as being expensive, -don't connect immediately. -This requires that queueing be compiled in, -since it will depend on a queue run process to -actually send the mail. -.ip HostsFile=\fIpath\fP -[no short name] -The path to the hosts database, -normally -.q /etc/hosts . -This option is only consulted when sendmail -is canonifying addresses, -and then only when -.q files -is in the -.q hosts -service switch entry. -In particular, this file is -.i never -used when looking up host addresses; -that is under the control of the system -.i gethostbyname (3) -routine. -.ip HostStatusDirectory=\fIpath\fP -[no short name] -The location of the long term host status information. -When set, -information about the status of hosts -(e.g., host down or not accepting connections) -will be shared between all -.i sendmail -processes; -normally, this information is only held within a single queue run. -This option requires a connection cache of at least 1 to function. -If the option begins with a leading `/', -it is an absolute pathname; -otherwise, -it is relative to the mail queue directory. -A suggested value for sites desiring persistent host status is -.q \&.hoststat -(i.e., a subdirectory of the queue directory). -.ip IgnoreDots -[i] -Ignore dots in incoming messages. -This is always disabled (that is, dots are always accepted) -when reading SMTP mail. -.ip LogLevel=\fIn\fP -[L] -Set the default log level to -.i n . -Defaults to 9. -.ip M\fIx\|value\fP -[no long version] -Set the macro -.i x -to -.i value . -This is intended only for use from the command line. -The -.b \-M -flag is preferred. -.ip MatchGECOS -[G] -Allow fuzzy matching on the GECOS field. -If this flag is set, -and the usual user name lookups fail -(that is, there is no alias with this name and a -.i getpwnam -fails), -sequentially search the password file -for a matching entry in the GECOS field. -This also requires that MATCHGECOS -be turned on during compilation. -This option is not recommended. -.ip MaxDaemonChildren=\fIN\fP -[no short name] -If set, -.i sendmail -will refuse connections when it has more than -.i N -children processing incoming mail. -This does not limit the number of outgoing connections. -If not set, there is no limit to the number of children -- -that is, the system load averaging controls this. -.ip MaxHopCount=\fIN\fP -[h] -The maximum hop count. -Messages that have been processed more than -.i N -times are assumed to be in a loop and are rejected. -Defaults to 25. -.ip MaxHostStatAge=\fIage\fP -[no short name] -Not yet implemented. -This option specifies how long host status information will be retained. -For example, if a host is found to be down, -connections to that host will not be retried for this interval. -The units default to minutes. -.ip MaxMessageSize=\fIN\fP -[no short name] -Specify the maximum message size -to be advertised in the ESMTP EHLO response. -Messages larger than this will be rejected. -.ip MaxQueueRunSize=\fIN\fP -[no short name] -The maximum number of jobs that will be processed -in a single queue run. -If not set, there is no limit on the size. -If you have very large queues or a very short queue run interval -this could be unstable. -However, since the first -.i N -jobs in queue directory order are run (rather than the -.i N -highest priority jobs) -this should be set as high as possible to avoid -.q losing -jobs that happen to fall late in the queue directory. -.ip MeToo -[m] -Send to me too, -even if I am in an alias expansion. -.ip MinFreeBlocks=\fIN\fP -[b] -Insist on at least -.i N -blocks free on the filesystem that holds the queue files -before accepting email via SMTP. -If there is insufficient space -.i sendmail -gives a 452 response -to the MAIL command. -This invites the sender to try again later. -.ip MinQueueAge=\fPage\fP -[no short name] -Don't process any queued jobs -that have been in the queue less than the indicated time interval. -This is intended to allow you to get responsiveness -by processing the queue fairly frequently -without thrashing your system by trying jobs too often. -The default units are minutes. -.ip MustQuoteChars=\fIs\fP -[no short name] -Sets the list of characters that must be quoted if used in a full name -that is in the phrase part of a ``phrase <address>'' syntax. -The default is ``\'.''. -The characters ``@,;:\e()[]'' are always added to this list. -.ip NoRecipientAction -[no short name] -The action to take when you receive a message that has no valid -recipient headers (To:, Cc:, Bcc:, or Apparently-To: \(em -the last included for back compatibility with old -.i sendmail s). -It can be -.b None -to pass the message on unmodified, -which violates the protocol, -.b Add-To -to add a To: header with any recipients it can find in the envelope -(which might expose Bcc: recipients), -.b Add-Apparently-To -to add an Apparently-To: header -(this is only for back-compatibility -and is officially deprecated), -.b Add-To-Undisclosed -to add a header -.q "To: undisclosed-recipients:;" -to make the header legal without disclosing anything, -or -.b Add-Bcc -to add an empty Bcc: header. -.ip OldStyleHeaders -[o] -Assume that the headers may be in old format, -i.e., -spaces delimit names. -This actually turns on -an adaptive algorithm: -if any recipient address contains a comma, parenthesis, -or angle bracket, -it will be assumed that commas already exist. -If this flag is not on, -only commas delimit names. -Headers are always output with commas between the names. -Defaults to off. -.ip OperatorChars=\fIcharlist\fP -[$o macro] -The list of characters that are considered to be -.q operators , -that is, characters that delimit tokens. -All operator characters are tokens by themselves; -sequences of non-operator characters are also tokens. -White space characters separate tokens -but are not tokens themselves \(em for example, -.q AAA.BBB -has three tokens, but -.q "AAA BBB" -has two. -If not set, OperatorChars defaults to -.q \&.\|:\|@\|[\|] ; -additionally, the characters -.q (\|)\|<\|>\|,\|; -are always operators. -.ip PostmasterCopy=\fIpostmaster\fP -[P] -If set, -copies of error messages will be sent to the named -.i postmaster . -Only the header of the failed message is sent. -Since most errors are user problems, -this is probably not a good idea on large sites, -and arguably contains all sorts of privacy violations, -but it seems to be popular with certain operating systems vendors. -Defaults to no postmaster copies. -.ip PrivacyOptions=\fI\|opt,opt,...\fP -[p] -Set the privacy -.i opt ions. -``Privacy'' is really a misnomer; -many of these are just a way of insisting on stricter adherence -to the SMTP protocol. -The -.i opt ions -can be selected from: -.(b -.ta \w'needvrfyhelo'u+3n -public Allow open access -needmailhelo Insist on HELO or EHLO command before MAIL -needexpnhelo Insist on HELO or EHLO command before EXPN -noexpn Disallow EXPN entirely -needvrfyhelo Insist on HELO or EHLO command before VRFY -novrfy Disallow VRFY entirely -restrictmailq Restrict mailq command -restrictqrun Restrict \-q command line flag -noreceipts Don't return success DSNs -goaway Disallow essentially all SMTP status queries -authwarnings Put X-Authentication-Warning: headers in messages -.)b -The -.q goaway -pseudo-flag sets all flags except -.q restrictmailq -and -.q restrictqrun . -If mailq is restricted, -only people in the same group as the queue directory -can print the queue. -If queue runs are restricted, -only root and the owner of the queue directory -can run the queue. -Authentication Warnings add warnings about various conditions -that may indicate attempts to spoof the mail system, -such as using an non-standard queue directory. -.ip QueueDirectory=\fIdir\fP -[Q] -Use the named -.i dir -as the queue directory. -.ip QueueFactor=\fIfactor\fP -[q] -Use -.i factor -as the multiplier in the map function -to decide when to just queue up jobs rather than run them. -This value is divided by the difference between the current load average -and the load average limit -(\c -.b QueueLA -option) -to determine the maximum message priority -that will be sent. -Defaults to 600000. -.ip QueueLA=\fILA\fP -[x] -When the system load average exceeds -.i LA , -just queue messages -(i.e., don't try to send them). -Defaults to 8. -.ip QueueSortOrder=\fIalgorithm\fP -[no short name] -Sets the -.i algorithm -used for sorting the queue. -Only the first character of the value is used. -Legal values are -.q host -(to order by the name of the first host name of the first recipient), -.q time -(to order by the submission time), -and -.q priority -(to order by message priority). -Host ordering makes better use of the connection cache, -but may tend to process low priority messages -that go to a single host -over high priority messages that go to several hosts; -it probably shouldn't be used on slow network links. -Time ordering is almost always a bad idea, -since it allows large, bulk mail to go out -before smaller, personal mail, -but may have applicability on some hosts with very fast connections. -Priority ordering is the default. -.ip QueueTimeout=\fItimeout\fP -[T] -A synonym for -.q Timeout.queuereturn . -Use that form instead of the -.q QueueTimeout -form. -.ip ResolverOptions=\fIoptions\fP -[I] -Set resolver options. -Values can be set using -.b + \c -.i flag -and cleared using -.b \- \c -.i flag ; -the -.i flag s -can be -.q debug , -.q aaonly , -.q usevc , -.q primary , -.q igntc , -.q recurse , -.q defnames , -.q stayopen , -or -.q dnsrch . -The string -.q HasWildcardMX -(without a -.b + -or -.b \- ) -can be specified to turn off matching against MX records -when doing name canonifications. -.b N.B. -Prior to 8.7, -this option indicated that the name server be responding -in order to accept addresses. -This has been replaced by checking to see -if the -.q dns -method is listed in the service switch entry for the -.q hosts -service. -.ip RunAsUser=\fIuser\fP -[no short name] -The -.i user -parameter may be a user name -(looked up in -.i /etc/passwd ) -or a numeric user id; -either form can have -.q ":group" -attached -(where group can be numeric or symbolic). -If set to a non-zero (non-root) value, -.i sendmail -will change to this user id shortly after startup\**. -.(f -\**When running as a daemon, -it changes to this user after accepting a connection -but before reading any -.sm SMTP -commands. -.)f -This avoids a certain class of security problems. -However, this means that all -.q \&.forward -and -.q :include: -files must be readable by the indicated -.i user , -and on systems that don't support the saved uid bit properly, -all files to be written must be writable by -.i user -and all programs will be executed by -.i user . -It is also incompatible with the -.b SafeFileEnvironment -option. -In other words, it may not actually add much to security on an average system, -and may in fact detract from security -(because other file permissions must be loosened). -However, it should be useful on firewalls and other -places where users don't have accounts and the aliases file is -well constrained. -.ip RecipientFactor=\fIfact\fP -[y] -The indicated -.i fact or -is added to the priority (thus -.i lowering -the priority of the job) -for each recipient, -i.e., this value penalizes jobs with large numbers of recipients. -Defaults to 30000. -.ip RefuseLA=\fILA\fP -[X] -When the system load average exceeds -.i LA , -refuse incoming SMTP connections. -Defaults to 12. -.ip RetryFactor=\fIfact\fP -[Z] -The -.i fact or -is added to the priority -every time a job is processed. -Thus, -each time a job is processed, -its priority will be decreased by the indicated value. -In most environments this should be positive, -since hosts that are down are all too often down for a long time. -Defaults to 90000. -.ip SafeFileEnvironment=\fIdir\fP -[no short name] -If this option is set, -.i sendmail -will do a -.i chroot (2) -call into the indicated -.i dir ectory -before doing any file writes. -If the file name specified by the user begins with -.i dir , -that partial path name will be stripped off before writing, -so (for example) -if the SafeFileEnvironment variable is set to -.q /safe -then aliases of -.q /safe/logs/file -and -.q /logs/file -actually indicate the same file. -Additionally, if this option is set, -.i sendmail -refuses to deliver to symbolic links. -.ip SaveFromLine -[f] -Save -Unix-style -.q From -lines at the front of headers. -Normally they are assumed redundant -and discarded. -.ip SendMIMEErrors -[j] -If set, send error messages in MIME format -(see RFC1521 and RFC1344 for details). -If disabled, -.i sendmail -will not return the DSN keyword in response to an EHLO -and will not do Delivery Status Notification processing as described in -RFC1891. -.ip ServiceSwitchFile=\fIfilename\fP -[no short name] -If your host operating system has a service switch abstraction -(e.g., /etc/nsswitch.conf on Solaris -or /etc/svc.conf on Ultrix and DEC OSF/1) -that service will be consulted and this option is ignored. -Otherwise, this is the name of a file -that provides the list of methods used to implement particular services. -The syntax is a series of lines, -each of which is a sequence of words. -The first word is the service name, -and following words are service types. -The services that -.i sendmail -consults directly are -.q aliases -and -.q hosts. -Service types can be -.q dns , -.q nis , -.q nisplus , -or -.q files -(with the caveat that the appropriate support -must be compiled in -before the service can be referenced). -If ServiceSwitchFile is not specified, it defaults to /etc/service.switch. -If that file does not exist, the default switch is: -.(b -aliases files -hosts dns nis files -.)b -The default file is -.q /etc/service.switch . -.ip SevenBitInput -[7] -Strip input to seven bits for compatibility with old systems. -This shouldn't be necessary. -.ip SingleLineFromHeader -[no short name] -If set, From: lines that have embedded newlines are unwrapped -onto one line. -This is to get around a botch in Lotus Notes -that apparently cannot understand legally wrapped RFC822 headers. -.ip SingleThreadDelivery -[no short name] -If set, a client machine will never try to open two SMTP connections -to a single server machine at the same time, -even in different processes. -That is, if another -.i sendmail -is already talking to some host a new -.i sendmail -will not open another connection. -This property is of mixed value; -although this reduces the load on the other machine, -it can cause mail to be delayed -(for example, if one -.i sendmail -is delivering a huge message, other -.i sendmail s -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 the -.b ConnectionCacheSize -option to avoid running out of per-process file descriptors. -Requires the -.b HostStatusDirectory -option. -.ip SmtpGreetingMessage=\fImessage\fP -[$e macro] -The message printed when the SMTP server starts up. -Defaults to -.q "$j Sendmail $v ready at $b". -.ip StatusFile=\fIfile\fP -[S] -Log summary statistics in the named -.i file . -If not set, -no summary statistics are saved. -This file does not grow in size. -It can be printed using the -.i mailstats (8) -program. -.ip SuperSafe -[s] -Be super-safe when running things, -i.e., -always instantiate the queue file, -even if you are going to attempt immediate delivery. -.i Sendmail -always instantiates the queue file -before returning control the client -under any circumstances. -This should really -.i always -be set. -.ip TempFileMode=\fImode\fP -[F] -The file mode for queue files. -It is interpreted in octal by default. -Defaults to 0600. -.ip Timeout.\fItype\fP=\|\fItimeout\fP -[r; subsumes old T option as well] -Set timeout values. -The actual timeout is indicated by the -.i type . -The recognized timeouts and their default values, and their -minimum values specified in RFC 1123 section 5.3.2 are: -.(b -.ta \w'datafinal'u+3n -initial wait for initial greeting message [5m, 5m]

-queuewarn\(dg how long until a warning is sent [none, none] -hoststatus\(dg how long until host status is ``stale'' [30m, none] -.)b -All but those marked with a dagger (\(dg) -apply to client SMTP. -If the message is submitted using the -.sm NOTIFY -.sm SMTP -extension, -warning messages will only be sent if -.sm NOTIFY=DELAY -is specified. -The queuereturn and queuewarn timeouts -can be further qualified with a tag based on the Precedence: field -in the message; -they must be one of -.q urgent -(indicating a positive non-zero precedence) -.q normal -(indicating a zero precedence), or -.q non-urgent -(indicating negative precedences). -For example, setting -.q Timeout.queuewarn.urgent=1h -sets the warning timeout for urgent messages only -to one hour. -The default if no precedence is indicated -is to set the timeout for all precedences. -.ip TimeZoneSpec=\fItzinfo\fP -[t] -Set the local time zone info to -.i tzinfo -\*- for example, -.q PST8PDT . -Actually, if this is not set, -the TZ environment variable is cleared (so the system default is used); -if set but null, the user's TZ variable is used, -and if set and non-null the TZ variable is set to this value. -.ip TryNullMXList -[w] -If this system is the -.q best -(that is, lowest preference) -MX for a given host, -its configuration rules should normally detect this situation -and treat that condition specially -by forwarding the mail to a UUCP feed, -treating it as local, -or whatever. -However, in some cases (such as Internet firewalls) -you may want to try to connect directly to that host -as though it had no MX records at all. -Setting this option causes -.i sendmail -to try this. -The downside is that errors in your configuration -are likely to be diagnosed as -.q "host unknown" -or -.q "message timed out" -instead of something more meaningful. -This option is disrecommended. -.ip UnixFromLine=\fIfromline\fP -[$l macro] -Defines the format used when -.i sendmail -must add a UNIX-style From_ line -(that is, a line beginning -.q From<space>user ). -Defaults to -.q "From $g $d" . -Don't change this unless your system uses a different UNIX mailbox format -(very unlikely). -.ip UnsafeGroupWrites -[no short name] -If set, -:include: and .forward files that are group writable are considered -.q unsafe , -that is, -they cannot reference programs or write directly to files. -World writable :include: and .forward files -are always unsafe.. -.ip UseErrorsTo -[l] -If there is an -.q Errors-To: -header, send error messages to the addresses listed there. -They normally go to the envelope sender. -Use of this option causes -.i sendmail -to violate RFC 1123. -This option is disrecommended and deprecated. -.ip UserDatabaseSpec=\fIudbspec\fP -[U] -The user database specification. -.ip UserSubmission -[no short name] -This is an initial submission directly from a Mail User Agent. -This can be set in the configuration file if you have -MUAs that don't pass the -.b \-U -flag or use the -XUSR -ESMTP extension, -but some relayed mail may get inappropriately rewritten if you do. -.ip Verbose -[v] -Run in verbose mode. -If this is set, -.i sendmail -adjusts options -.b HoldExpensive -(old -.b c ) -and -.b DeliveryMode -(old -.b d ) -so that all mail is delivered completely -in a single job -so that you can see the entire delivery process. -Option -.b Verbose -should -.i never -be set in the configuration file; -it is intended for command line use only. -.lp -All options can be specified on the command line using the -\-O or \-o flag, -but most will cause -.i sendmail -to relinquish its setuid permissions. -The options that will not cause this are -MinFreeBlocks [b], -DeliveryMode [d], -ErrorMode [e], -IgnoreDots [i], -LogLevel [L], -MeToo [m], -OldStyleHeaders [o], -PrivacyOptions [p], -Timeouts [r], -SuperSafe [s], -Verbose [v], -CheckpointInterval [C], -and -SevenBitInput [7]. -Also, M (define macro) when defining the r or s macros -is also considered -.q safe . -.sh 2 "P \*- Precedence Definitions" -.pp -Values for the -.q "Precedence:" -field may be defined using the -.b P -control line. -The syntax of this field is: -.(b -\fBP\fP\fIname\fP\fB=\fP\fInum\fP -.)b -When the -.i name -is found in a -.q Precedence: -field, -the message class is set to -.i num . -Higher numbers mean higher precedence. -Numbers less than zero -have the special property -that if an error occurs during processing -the body of the message will not be returned; -this is expected to be used for -.q "bulk" -mail such as through mailing lists. -The default precedence is zero. -For example, -our list of precedences is: -.(b -Pfirst-class=0 -Pspecial-delivery=100 -Plist=\-30 -Pbulk=\-60 -Pjunk=\-100 -.)b -People writing mailing list exploders -are encouraged to use -.q "Precedence: list" . -Older versions of -.i sendmail -(which discarded all error returns for negative precedences) -didn't recognize this name, giving it a default precedence of zero. -This allows list maintainers to see error returns -on both old and new versions of -.i sendmail . -.sh 2 "V \*- Configuration Version Level" -.pp -To provide compatibility with old configuration files, -the -.b V -line has been added to define some very basic semantics -of the configuration file. -These are not intended to be long term supports; -rather, they describe compatibility features -which will probably be removed in future releases. -.pp -.b N.B.: -these version -.i levels -have nothing -to do with the version -.i number -on the files. -For example, -as of this writing -version 8 config files -(specifically, 8.7) -used version level 6 configurations. -.pp -.q Old -configuration files are defined as version level one. -Version level two files make the following changes: -.np -Host name canonification ($[ ... $]) -appends a dot if the name is recognized; -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 $w -to be just the first component of the hostname. -.pp -Version level six configuration files -change many of the local processing options -(such as aliasing and matching the beginning of the address for -`|' characters) -to be mailer flags; -this allows fine-grained control over the special local processing. -Level six configuration files may also use long option names. -The -.b ColonOkInAddr -option (to allow colons in the local-part of addresses) -defaults -.b on -for lower numbered configuration files; -the configuration file requires some additional intelligence -to properly handle the RFC 822 group construct. -.pp -The -.b V -line may have an optional -.b / \c -.i vendor -to indicate that this configuration file uses modifications -specific to a particular vendor\**. -.(f -\**And of course, vendors are encouraged to add themselves -to the list of recognized vendors by editing the routine -.i setvendor -in -.i conf.c . -Please send e-mail to sendmail@Sendmail.ORG -to register your vendor dialect. -.)f -You may use -.q /Berkeley -to emphasize that this configuration file -uses the Berkeley dialect of -.i sendmail . -.sh 2 "K \*- Key File Declaration" -.pp -Special maps can be defined using the line: -.(b -Kmapname mapclass arguments -.)b -The -.i mapname -is the handle by which this map is referenced in the rewriting rules. -The -.i mapclass -is the name of a type of map; -these are compiled in to -.i sendmail . -The -.i arguments -are interpreted depending on the class; -typically, -there would be a single argument naming the file containing the map. -.pp -Maps are referenced using the syntax: -.(b -$( \fImap\fP \fIkey\fP $@ \fIarguments\fP $: \fIdefault\fP $) -.)b -where either or both of the -.i arguments -or -.i default -portion may be omitted. -The -.i "$@ arguments" -may appear more than once. -The indicated -.i key -and -.i arguments -are passed to the appropriate mapping function. -If it returns a value, it replaces the input. -If it does not return a value and the -.i default -is specified, the -.i default -replaces the input. -Otherwise, the input is unchanged. -.pp -The -.i arguments -are passed to the map for arbitrary use. -Most map classes can interpolate these arguments -into their values using the syntax -.q %\fIn\fP -(where -.i n -is a digit) -to indicate the corresponding -.i argument . -Argument -.q %0 -indicates the database key. -For example, the rule -.(b -.ta 1.5i -R$\- ! $+ $: $(uucp $1 $@ $2 $: %1 @ %0 .

-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 <email address>" -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.

contributed code, -and many more have contributed ideas, comments, and encouragement. -I've tried to list them in the RELEASE_NOTES in the distribution directory. -I appreciate their contribution as well. -.pp -Special thanks are reserved for Michael Corrigan and Christophe Wolfhugel, -who besides being wonderful guinea pigs and contributors -have also consented to be added to the ``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

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

identifier, -.b R -to limit based on recipient, -or -.b S -to limit based on sender. -A particular queued job is accepted if one of the corresponding addresses -contains the indicated -.i string . -.ip "\-R ret" -What information you want returned if the message bounces; -.i ret -can be -.q HDRS -for headers only or -.q FULL -for headers plus body. -This is a request only; -the other end is not

"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

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 ?

DO NOT USE MAKE !! to compile sendmail -- instead, use the -********************* "makesendmail" script located in the src -directory. It will find an appropriate Makefile, and create an -appropriate obj.* subdirectory so that multiplatform support -works easily. - -The Makefile is for the new (4.4BSD) Berkeley make and uses syntax -that is not recognized by older makes. It also has assumptions -about the 4.4 file system layout built in. See below for details -about other Makefiles. - -If you are porting to a new architecture for which there is no existing -Makefile, you might start with Makefile.dist.

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 <pauls@umich.edu> 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 <errno.h>), 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 <sys/statfs.h>), - SFS_VFS (3), SFS_MOUNT (4), SFS_STATFS (5) if you have - the two-argument statfs(2) system call with includes in - <sys/vfs.h>, <sys/mount.h>, or <sys/statfs.h> 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.

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. It was decided that the only - >> secure way to do this was to allow a `trusted' path to be used in - >> LD_LIBRARY_PATH. The only trusted directory we presently define - >> is /usr/lib. Thus a setuid root developer could play with some - >> alternative shared object implementations and place them in - >> /usr/lib (being root we assume they'ed have access to write in this - >> directory). This change was made as part of 1155380 - after a - >> *huge* amount of discussion regarding the security aspect of things. - >> - >> So, in SunOS 5.4 your applications search path would be: - >> - >> /usr/local/lib from LD_LIBRARY_PATH - IGNORED (untrustworthy) - >> /usr/lib from LD_LIBRARY_PATH - honored (trustworthy) - >> /usr/local/lib from RPATH - honored - >> /usr/lib from RPATH - honored - >> - >> here, path 2 would be the first used. - -Solaris 2.6 (SunOS 5.6) - If you built sendmail 8.8.1 through 8.8.4 inclusive on a Solaris 2.5 - system, that binary will not run on Solaris 2.6, due to problems with - incompatible snprintf(3s) calls. 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 <de5@ornl.gov>, 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 <sys/dir.h> - #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" <hagberg@med.cornell.edu> - 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 <tom@stallion.oz.au> - 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 <dlander@afterlife.ncsc.mil> 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 <sys/dir.h> - #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 <Kimmo.Suominen@lut.fi> - 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 <jmaki@hut.fi> 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 <markw@antimatr.houston.tx.us> - 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 <markw@antimatr.houston.tx.us>. - 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" <kim@grendel.lut.fi> - 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 <sys/signal.h>. - 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 <sasha@unitech.gamma.ru>, - 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 <jgd@acl.lanl.gov>. - -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 <bbense@networking.stanford.edu> 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_<VER>.tar.gz (where <VER> 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.
