This means that when you +install it, if you have any "crontab" command lines floating around in shell +scripts (such as /etc/rc or /etc/rc.local), you will need to change them. + +I have integrated several changes made by BSDi for their BSD/386 operating +system; these were offerred to me before I started consulting for them, so +it is safe to say that they were intended for publication. Most notably, +the name of the cron daemon has changed from "crond" to "cron". This was +done for compatibility with 4.3BSD. Another change made for the same reason +is the ability to read in an /etc/crontab file which has an extra field in +each entry, between the time fields and the command. This field is a user +name, and it permits the /etc/crontab command to contain commands which are +to be run by any user on the system. /etc/crontab is not "installed" via +the crontab(1) command; it is automatically read at startup time and it will +be reread whenever it changes. + +I also added a "-e" option to crontab(1). Nine people also sent me diffs +to add this option, but I had already implemented it on my own. I actually +released an interrim version (V2.2, I think) for limited testing, and got a +chance to fix a bad security bug in the "-e" option thanks to XXX. + +The daemon used to be extraordinarily sloppy in its use of file descriptors. +A heck of a lot of them were left open in spawned jobs, which caused problems +for the daemon and also caused problems with the spawned jobs if they were +shell scripts since "sh" and "csh" have traditionally used hidden file +descriptors to pass information to subshells, and cron was causing them to +think they were subshells. If you had trouble with "sh" or "csh" scripts in +V2, chances are good that V3 will fix your problems. + +About a dozen people have reminded me that I forgot to initialize +"crontab_fd" in database.c. Keith Cantrell was the first, so he gets the +point. + +Steve Simmons reminded me that once an account has been deleted from the +system, "crontab -u USER -d" will not work. My solution is to suggest to +all of you that before you delete a user's account, you first delete that +user's crontab file if any. From cron's point of view, usernames can never +be treated as arbitrary strings. Either they are valid user names, or they +are not. I will not make an exception for the "-d" case, for security +reasons that I consider reasonable. It is trivial for a root user to delete +the entry by hand if necessary. + +Dan O'Neil reminded me that I forgot to reset "log_fd" in misc.c. A lot of +others also reminded me of this, but Dan gets the point. I didn't fix it +there, since the real bug was that it should have been open in the parent. + +Peter Kabal reminded me that I forgot to "#ifdef DEBUGGING" some code in +misc.c. Hans Trompert actually told me first, but Peter sent the patch so +he gets the point. + +Russell Nelson told me that I'd forgotten to "#include <syslog.h>" in misc.c, +which explains why a lot of other people complained that it wasn't using +syslog even when they configured it that way :-). Steve Simmons told me +first, though, so he gets the point. + +An interrim version of the daemon tried to "stat" every file before +executing it; this turned out to be a horribly bad idea since finding the +name of a file from a shell command is a hard job (that's why we have +shells, right?) I removed this bogus code. Dave Burgess gets the point. + +Dennis R. Conley sent a suggestion for MMDF systems, which I've added to the +comments in cron.h. + +Mike Heisler noted that I use comments in the CONVERSION file which are +documented as illegal in the man pages. Thanks, Mike. + +Irving Wolfe sent me some very cheerful changes for a NeXT system, but I +consider the system itself broken and I can't bring myself to #ifdef for +something as screwed up as this system seems to be. However, various others +did send me smaller patches which appear to have cause cron to build and run +correctly on (the latest) NeXT machines, with or without the "-posix" CFLAG. +Irving also asked for a per-job MAILTO, and this was finally added later when +I integrated the BSD/386 changes contributed by BSDi, and generalized some of +the parsing. + +Lots of folks complained that the autogenerated "Date:" header wasn't in +ARPA format. I didn't understand this -- either folks will use Sendmail and +not generate a Date: at all (since Sendmail will do it), or folks will use +something other than Sendmail which won't care about Date: formats. But +I've "fixed" it anyway... + +Several people suggested that "*" should be able to take a "/step". One person +suggested that "N/step" ought to mean "N-last/step", but that's stretching things +a bit far. "*/step" seems quite intuitive to me, so I've added it. Colin Plumb +sent in the first and most polite request for this feature. + +As with every release of Cron, BIND, and seemingly everything else I do, one +user stands out with the most critical but also the most useful analysis. +Cron V3's high score belongs to Peter Holzer, who sent in the nicest looking +patch for the "%" interpretation problem and also helped me understand a +tricky bit of badness in the "log_fd" problem. + +agulbra@flode.nvg.unit.no wins the honors for being the first to point out the +nasty security hole in "crontab -r". 'Nuff said. + +Several folks pointed out that log_it() needed to exist even if logging was +disabled. Some day I will create a tool that will compile a subsystem with +every possible combination and permutation of #ifdef options, but meanwhile +thanks to everybody. + +job_runqueue() was using storage after freeing it, since Jordan told me back +in 1983 that C let you do that, and I believed him in 1986 when I wrote all +this junk. Linux was the first to die from this error, and the Linux people +sent me the most amazing, um, collection of patches for this problem. Thanks +for all the fish. + +Jeremy Bettis reminded me that popen() isn't safe. I grabbed Ken Arnold's +version of popen/pclose from the ftpd and hacked it to taste. We're safe now, +from this at least. + +Branko Lankester sent me a very timely and helpful fix for a looming security +problem in my "crontab -e" implementation. + +-------- + +Vixie Cron Changes from V1 to V2 +Paul Vixie +8-Feb-1988 + +Many changes were made in a rash of activity about six months ago, the exact +list of which is no longer clear in my memory. I know that V1 used a file +called POKECRON in /usr/spool/cron to tell it that it was time to re-read +all the crontab files; V2 uses the modtime the crontab directory as a flag to +check out the crontab files; those whose modtime has changed will be re-read, +and the others left alone. Note that the crontab(1) command will do a utimes +call to make sure the mtime of the dir changes, since the filename/inode will +often remain the same after a replacement and the mtime wouldn't change in +that case. + +8-Feb-88: made it possible to use much larger environment variable strings. + V1 allowed 100 characters; V2 allows 1000. This was needed for PATH + variables on some systems. Thanks to Toerless Eckert for this idea. + E-mail: UUCP: ...pyramid!fauern!faui10!eckert + +16-Feb-88: added allow/deny, moved /usr/spool/cron/crontabs to + /usr/lib/cron/tabs. allow and deny are /usr/lib/cron/{allow,deny}, + since the sysv naming for this depends on 'at' using the same + dir, which would be stupid (hint: use /usr/{lib,spool}/at). + +22-Feb-88: made it read the spool directory for crontabs and look each one + up using getpwnam() rather than reading all passwds with getpwent() + and trying to open each crontab. + +9-Dec-88: made it sync to :00 after the minute, makes cron predictable. + added logging to /var/cron/log. + +14-Apr-90: (actually, changes since December 1989) + fixed a number of bugs reported from the net and from John Gilmore. + added syslog per Keith Bostic. security features including not + being willing to run a command owned or writable by other than + the owner of the crontab 9not working well yet) diff --git a/usr.sbin/cron/FEATURES b/usr.sbin/cron/FEATURES new file mode 100644 index 000000000000..516a7e21e374 --- /dev/null +++ b/usr.sbin/cron/FEATURES @@ -0,0 +1,84 @@ +$Id: FEATURES,v 1.1 1994/01/27 19:18:57 nate Exp $ + +Features of Vixie's cron relative to BSD 4.[23] and SysV crons: + +-- Environment variables can be set in each crontab.

This + feature mimics the SysV cron. + +-- The 'crontab' command is loosely compatible with SysV, but has more + options which just generally make more sense. Running crontab with + no arguments will print a cute little summary of the command syntax. + +-- Comments and blank lines are allowed in the crontab file. Comments + must be on a line by themselves; leading whitespace is ignored, and + a '#' introduces the comment. + +-- (big win) If the `crontab' command changes anything in any crontab, + the 'cron' daemon will reload all the tables before running the + next iteration. In some crons, you have to kill and restart the + daemon whenever you change a crontab. In other crons, the crontab + file is reread and reparsed every minute even if it didn't change. + +-- In order to support the automatic reload, the crontab files are not + readable or writable except by 'crontab' or 'cron'. This is not a + problem, since 'crontab' will let you do pretty much whatever you + want to your own crontab, or if you are root, to anybody's crontab. + +-- If any output is generated by a command (on stdout OR stderr), it will + be mailed to the owner of the crontab that contained the command (or + MAILTO, see discussion of environment variables, above).

It +is functionally based on the SysV cron, which means that each user can have +their own crontab file (all crontab files are stored in a read-protected +directory, usually /var/cron/tabs). No direct support is provided for +'at'; you can continue to run 'atrun' from the crontab as you have been +doing. If you don't have atrun (i.e., System V) you are in trouble. + +A messages is logged each time a command is executed; also, the files +"allow" and "deny" in /var/cron can be used to control access to the +"crontab" command (which installs crontabs). It hasn't been tested on +SysV, although some effort has gone into making the port an easy one. + +This is more or less the copyright that USENET contributed software usually +has. Since ATT couldn't use this version if they had to freely distribute +source, and since I'd love to see them use it, I'll offer some rediculously +low license fee just to have them take it.

Development continued in that tree until 4.4BSD + was released, when everything on the 4.4 tape was set to be + version 8.1. Version 7.x never existed. +---------------------------------------------------------------------- + * Where can I get Version 8? + + Via anonymous FTP from FTP.CS.Berkeley.EDU in /ucb/sendmail. +---------------------------------------------------------------------- + * Version 8 requires a new version of "make". Where can I get this? + + Actually, Version 8 does not require a new version of "make". + It includes a collection of Makefiles for different architectures, + only one or two of which require the new "make". If you are + porting to a new architecture, start with Makefile.dist. + + If you really do want the new make, it is available on any of + the BSD Net2 distribution sites. These include: + + ftp.uu.net /systems/unix/bsd-sources + gatekeeper.dec.com /.0/BSD/net2 + ucquais.cba.uc.edu /pub/net2 + ftp.luth.se /pub/unix/4.3bsd/net2 + + 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. +---------------------------------------------------------------------- + * What macro package do I use to format the V8 man pages? + + The BSD group switched over the the ``mandoc'' macros for + the 4.4 release. These include more hooks designed for + hypertext handling. However, new man pages won't format + under the old man macros. Fortunately, old man pages will + format under the new mandoc macros. + + Get the new macros with the BSD Net2 release. + + This macro set is also available with newer versions of groff. +---------------------------------------------------------------------- + * What books are available describing sendmail? + + There is one book available devoted to sendmail, and + several books that have sendmail chapters. + + Nemeth, Snyder, and Seebass, _Unix System Administration + Handbook_. Prentice-Hall. + Carl-Mitchell and Quarterman, _Practical Internetworking with + TCP/IP and UNIX_. Addison-Wesley. + Hunt, _TCP/IP Network Administration_. O'Reilly & Associates. + Costales, Allman, and Rickert, _Sendmail_. O'Reilly & + Associates. + + Another book is due out "soon": + + Avolio & Vixie, _Sendmail Theory and Practice_. Digital + Press (release date unknown). +---------------------------------------------------------------------- + * How do I make all my addresses appear to be from a single host? + + Using the V8 configuration macros, use: + + MASQUERADE_AS(my.dom.ain) + + This will cause all addresses to be sent out as being from + the indicated domain. +---------------------------------------------------------------------- + * How do I rewrite my From: lines to read ``First_Last@My.Domain''? + + There are a couple of ways of doing this. This describes using + the "user database" code. This is still experimental, and was + intended for a different purpose -- however, it does work + with a bit of care. It does require that you have the Berkeley + "db" package installed (it won't work with DBM). + + First, create your input file. This should have lines like: + + loginname:mailname First_Last + First_Last:maildrop loginname + + Install it in (say) /etc/userdb. Create the database: + + makemap btree /etc/userdb.db < /etc/userdb + + You can then create a config file that uses this. You will + have to include the following in your .mc file: + + define(confUSERDB_SPEC, /etc/userdb.db) + FEATURE(notsticky) +---------------------------------------------------------------------- + * So what was the user database feature intended for? + + The intent was to have all information for a given user (where + the user is the unique login name, not an inherently non-unique + full name) in one place. This would include phone numbers, + addresses, and so forth. The "maildrop" feature is because + Berkeley does not use a centralized mail server (there are a + number of reasons for this that are mostly historic), and so + we need to know where each user gets his or her mail delivered -- + i.e., the mail drop. + + We are in the process of setting up our environment so that + mail sent to an unqualified "name" goes to that person's + preferred maildrop; mail sent to "name@host" goes to that + host. The purpose of "FEATURE(notsticky)" is to cause + "name@host" to be looked up in the user database for delivery + to the maildrop. +---------------------------------------------------------------------- + * Why are you so hostile to using full names for e-mail addresses? + + Because full names are not unique. For example, the computer + community has two Andy Tannenbaums and two Peter Deutsches. + At one time, Bell Labs had two Stephen R. Bournes with offices + a few doors apart. You can create alternative addresses + (e.g., Stephen_R_Bourne_2), but that's even worse -- which + one of them has to have their name desecrated in this way? + And you can bet that they will get most of the other person's + email. + + So called "full names" are just longer versions of unique + names. Rather that lulling people into a sense of security, + I'd rather that it be clear that these handles are arbitrary. + People should use good user agents that have alias mappings + so that they can attach arbitrary names for their personal + use to those with whom they correspond. + + Even worse is fuzzy matching in e-mail -- this can make good + addresses turn bad. For example, I'm currently (to the best + of my knowledge) the only ``Allman'' at Berkeley, so mail + sent to "Allman@Berkeley.EDU" should get to me. But if + another Allman ever appears, this address could suddenly + become ambiguous. I've been the only Allman at Berkeley for + over fifteen years -- to suddenly have this "good address" + bounce mail because it is ambiguous would be a heinous wrong. + + Finger services should be as fuzzy as possible. Mail services + should be unique. +---------------------------------------------------------------------- + * When I use sendmail V8 with a Sun config file I get lines like: + + /etc/sendmail.cf: line 273: replacement $3 out of bounds + + the line in question reads: + + R$*<@$%y>$* $1<@$2.LOCAL>$3 user@ether + + what does this mean? How do I fix it? + + V8 doesn't recognize the Sun "$%y" syntax, so as far as it + is concerned, there is only a $1 and a $2 (but no $3) in this + line. Read Rick McCarty's paper on "Converting Standard Sun + Config Files to Sendmail Version 8", in the contrib directory + (file "converting.sun.configs") on the sendmail distribution + for a full discussion of how to do this. +---------------------------------------------------------------------- + * Should I use a wildcard MX for my domain? + + If at all possible, no. + + Wildcard MX records have lots of semantic "gotcha"s. For + example, they will match a host "unknown.your.domain" -- if + you don't explicitly test for unknown hosts in your domain, + you will get "config error: mail loops back to myself" + errors. +---------------------------------------------------------------------- + * I'm connected to the network via a SLIP link. Sometimes my sendmail + process hangs (although it looks like part of the message has been + transfered). Everything else works. What's wrong? + + Most likely, the problem isn't sendmail at all, but the low + level network connection. It's important that the MTU (Maximum + Transfer Unit) for the SLIP connection be set properly at both + ends. If they disagree, large packets will be trashed and + the connection will hang. +---------------------------------------------------------------------- + * I just upgraded to 8.x and suddenly I'm getting messages in my + syslog of the form "collect: I/O error on connection". What is + going wrong? + + Nothing. This is just a diagnosis of a condition that had + not been diagnosed before. If you are getting a lot of these + from a single host, there is probably some incompatibility + between 8.x and that host. If you get a lot of them in general, + you may have network problems that are causing connections to + get reset. +---------------------------------------------------------------------- + * How can I get sendmail to deliver local mail to $HOME/.mail + instead of into /usr/spool/mail (or /usr/mail)? + + This is a local mailer issue, not a sendmail issue. Either + modify your local mailer (source code will be required) or + change the program called in the "local" mailer configuration + description to be a new program that does this local delivery. + I understand that "procmail" works well, although I haven't + used it myself. +---------------------------------------------------------------------- + * Under V8, the "From " header gets mysteriously munged when I send + to an alias. + + ``It's not a bug, it's a feature.'' This happens when you have + a "owner-list" alias and you send to "list". V8 propogates the + owner information into the envelope sender field (which appears + as the "From " header on UNIX mail or as the Return-Path: header) + so that downstream errors are properly returned to the mailing + list owner instead of to the sender. In order to make this + appear as sensible as possible to end users, I recommend making + the owner point to a "request" address -- for example: + + list: :include:/path/name/list.list + owner-list: list-request + list-request: eric + + This will make message sent to "list" come out as being + "From list-request" instead of "From eric". +---------------------------------------------------------------------- + * There are four UUCP mailers listed in the configuration files. + Which one should I use? + + The choice 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. + + If you can't avoid it, you'll have to find the version that is + closest to what the other end accepts. Following is a summary + of the UUCP mailers available. + + 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. + + 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"). + + 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 +---------------------------------------------------------------------- + * I'm trying to to get my mail to go into queue only mode, and it + delivers the mail interactively anyway. (Or, I'm trying to use + the "don't deliver to expensive mailer" flag, and it doesn't + delivers the mail interactively anyway.) I can see it does it: + here's the output of "sendmail -v foo@somehost" (or Mail -v or + equivalent). + + The -v flag to sendmail (which is implied by the -v flag to + Mail and other programs in that family) tells sendmail to + watch the transaction. Since you have explicitly asked to + see what's going on, it assumes that you do not want to to + auto-queue, and turns that feature off. Remove the -v flag + and use a "tail -f" of the log instead to see what's going on. + + If you are trying to use the "don't deliver to expensive mailer" + flag (mailer flag "e"), be sure you also turn on global option + "c" -- otherwise it ignores the mailer flag. +---------------------------------------------------------------------- + * I'm getting "Local configuration error" messages, such as: + + 553 relay.domain.net config error: mail loops back to myself + 554 <user@domain.net>... Local configuration error + + How can I solve this problem? + + You have asked mail to the domain (e.g., domain.net) to be + forwarded to a specific host (in this case, relay.domain.net) + by using an MX record, but the relay machine doesn't recognize + itself as domain.net. Add domain.net to /etc/sendmail.cw + (if you are using FEATURE(use_cw_file)) or add "Cw domain.net" + to your configuration file. +---------------------------------------------------------------------- + * I want to run Sendmail version 8 on my DEC system, but you don't + have MAIL11V3 support in sendmail.

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. + +* No "exposed users" in "nullrelay" configuration. + + The "nullrelay" configuration hides all addresses behind the mail + hub name. Some sites might prefer to expose some names such as + root. This information is always available in Received: lines. + +* $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. + +* REDIRECT aliases don't work with `n' option. + + If you have option `n' set when you use newaliases and have + REDIRECT addresses in your aliases file, you'll get the error + messages during the newaliases instead of when email is sent to + the address in question. The workaround is to turn off the `n' + option. + +* MX records that point at non-existent hosts work strangly. + + Consider the DNS records: + + hostH MX 1 hostA + MX 2 hostB + hostA A 128.32.8.9 + + (note that there is no A record for hostB). If hostA is down, + an attempt to send to hostH gives "host unknown" -- that is, it + reflects out the status on the last host it tries, which in this + case is hostB, which is unknown. It probably ought to eliminate + hostB early in processing. + +* NAME environment variables with commas break. + + If you define your NAME environment variable to have a comma + (e.g., ``Lastname, Firstname''), and you are using the $q definition + that uses ``name <address>'' format, sendmail treats the first and + last names as two addresses, thus producing a bogus From line. You + can work around this by changing the $q definition to use + ``address (name)''. + +* \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. + +* DEC Alphas (OSF/1 1.3) sometimes time out on sending mail. + + I have one report that DEC Alphas acting as SMTP clients sometimes + will apparently not see the "250 OK" message in response to the + dot that indicates the end of the message. This only happens if + the message is run from the queue -- if it gets through on first + try, everything is fine. I have been unable to reproduce this + problem at Berkeley. + +* 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.) + +* Sending user deletion not done properly in :include: lists. + + If you don't have the "m" (me too) option set, then a person + sending to a list that contains themselves should not get a copy + of the message. However, if that list points to a :include: file + that has one address per line, this will break, and the sender + will always get a copy of their own message, just as though the + "m" option were set. + + You can eliminate this by adding commas at the end of each line + of the :include: file. + +* 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.

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/shell 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 wierd 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 Rochester University. + 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 ${HOSTALIASES} is set, use it during canonification 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 wierd 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.

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.

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. + +8.6.3/8.6.3 93/10/24 + IMPORTANT FIX: Fix several problems that caused open files to + be "lost" during queue runs; this overflowed the open + file table on large runs. An assumption that fdopen + always succeeds sometimes resulted in core dumps when + this happens; sometimes the message is delivered twice, + sometimes (probably) infinite times. This problem in + various form was reported by P{r (Pell) Emanuelsson and + Robert Campbell of U.C. Berkeley. + Special diagnosis of EMFILE error conditions -- it now prints + the known open file descriptors so you can figure out + what is consuming so much resources. + Fix a couple of problems caused by early address parsing + errors -- one caused it to return a "this is only a + warning" when it really wasn't, and the other started + parsing through a random pointer. The first was + noted by Eric Wassenaar. + Fix an infinite loop problem caused by null components in the + host signature. Problem noted by Jan Sorensen. + Be sure to reset the "current date" when sending an error + message -- PostMasterCopy messages were being sent + with an old Date: header. + Fix a problem that caused duplicated mail when sendmail was + (1) compiled without HASFLOCK, (2) you are sending to + an alias that has an owner-* alias, (3) you execute + sendmail with -t flag, (4) you run in -odb mode, and + (5) the sender specifies both the alias name and + another alias [i.e., the envelope is split], then + duplicate messages are sent. The problem description + and one-line fix are from Motonori Nakamura of Kyoto + University. + Avoid a problem that causes error messages to be discarded + in some cases -- this was the result of a "fix" to + avoid duplicate error messages, but two are better + than zero. Reported by Tim Rylance. + Fix a minor botch in checkfd012() -- fix from Dave Hill of + Computervision R&D Ltd. + Remove "X-Authentication-Warning: <user> set sender to <address> + using -f" entirely -- it is far too eager to include + this, and it is confusing folks. I'll try to make it + work "right" in 8.7. Problem noted by Yoshitaka + Tokugawa of dit Co., Ltd. + Fix a race condition with the errno value in tick() and + reapchild() -- this caused occasional misdiagnosis + of problems. Kyle Jones of UUNET helped this along. + Repair rule loop-detection code. From Michael Corrigan of + U.C.

Fix from J.R. + Oldroyd of Opal. + Previously, sendmail assumed that any SMTP greeting message + that wasn't 2xx was a temporary failure -- it should + only take 4xx as a temporary failure, and return a + solid error message on anything else -- for example, + to allow you to reject connections on a workstation + that is MXed to a mail server. + Portability enhancements for 386BSD/FreeBSD/NetBSD from + Ollivier Robert. + CONFIG: FEATURE(always_add_domain) didn't always add the domain; + in particular, on local mail it modified the header sender + but not the header recipient address(es).

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.

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.

In the longer term, +it is recommended that one move to using an m4 based configuration such +as those shipped with sendmail, but if you're like me and have made +enough modifications to your .cf file that you'd rather put that task +off until later, here's the sum total of my experience to get you to +version 8 with minimal pain. I'll cover .cf as well as build issues. + +Some background - as many are surely aware, Sun has some "special" +features in the sendmail they ship ($%x, %y LHS lookup, NIS alias DB +search, etc.). (Some of those features can be had in alternative forms +in IDA sendmail, but v8 has picked up some IDA capabilities as well as +new ones, making it IMHO a most desirable version to go to.) What I +will explain below includes v8 functional "equivalences" to these Sun +sendmail features. + +So with that out of the way, let's begin. + +First, some assumptions: + + 1) I'm going to assume you've got sendmail version 8.6 or + later in hand - if not, grab it from ftp.cs.berkeley.edu + in the ucb/sendmail directory. There are bugs in earlier + versions which affect some of the needed functionality. + + 2) Second, I'm going to detail this based upon the + "sendmail.main.cf" configuration. (BTW, if you attempt + to move to using an m4 generated config in the future, + MAIL_HUB is the feature which should provide similar + functionality). + + In general, the changes will be similar for a subsidiary + file, but since we (my TI group) funnel all non-local mail + through our mailhost, we're not as interested in getting v8 + to run on such systems and I haven't tried it. + + 3) You're using DNS and sendmail.mx. If you're not, you ought + to be, even if you're also running it along with NIS (which + we do - except for gethostbyxxx() lookups, which I'll be + talking about later). I would imagine you could get things + running OK without DNS support, but I haven't tried it myself. + + 4) You're not mounting /var/spool/mail from other systems. + I haven't found a v8 feature to guarantee this will work + correctly. Anyway, in the past, we've tried doing that + here and found it to be a rather "ugly" feature, though + Sun ostensibly supports it ("R" option). Perhaps v8 + will one day have a similar feature, but for now, bottom + line, I would recommend against it. + + 5) You're not on Solaris or using NIS+. I'm on 4.1.3. I've + looked at Solaris briefly and have noted that things are + pretty much similar there except that they've moved some + things into the /etc/mail directory. I'd guess the + executables aren't functionally all that different from + what they had before - the configs are roughly the same. + So I'd bet most of what I say in here will apply to + Solaris. + +OK, let's configure our sendmail.cf! I'll just go from the top down... + + VARIOUS DECLARATIONS + +1) For v8, you need to define your .cf as AT LEAST a version level 4 + configuration. Add the following line: + + V4 + + There are some issues regarding certain predefined macros - $w, $j, and + $m. With a V4 configuration: + + $w is defined to be the hostname, which will usually be fully + qualified (i.e. "firefly.add.itg.ti.com"). + + $j should have the same value as $w. + + $m will be predefined as the domain portion of $w + (ex. "add.itg.ti.com"). + + One note about this - if your configuration relies on the "w" macro to + be the "simple" hostname (as mine does)... + + If the configuration version is 5 or larger: + + $w is supposed to be the "simple" name (ex. "firefly") + + $j should be the fully qualified name (i.e. "firefly.add.itg.ti.com") + + $m will be predefined as the domain portion of $j + (ex. "add.itg.ti.com"). + + I have not experimented with the various combinations, so I cannot + guarantee you that the above definitions will always come out as + expected. Bottom line: if your sendmail.cf depends on $w being the + simple hostname, test it carefully or define the name explicitly, + for example: + + Dwfirefly + +2) To replace the Sun's "%y" feature, we must use a hostname mapping + feature in v8. If you want to do similar lookups with v8, you need + to define the following map (we'll go over the rules that use this + map later): + + Khostlookup host -f -m -a. + + This will define a "lookup only" map that is otherwise the same as + sendmail version 8's built-in "host" map (see the "Sendmail + Installation and Operation Guide" for details on this map.). + + An important note: Whether or not these lookups will be done via + NIS is a function of what gethostbyxxx() functions you link into + your sendmail. DO NOT redefine your host mapping to use NIS + explicitly within sendmail - there can be unexpected behaviour if + you do so (if you do any canonicalization in your .cf, you can get + incorrect results, for one thing). + + For example, DO NOT TRY: + + Khost nis -f -a. hosts.byname + +3) If you're doing reverse alias mapping as done in ruleset 22, instead of: + + DZmail.byaddr + + you'll need to declare the following: + + Kaliasrev nis -f -N mail.byaddr + +4) If you are doing any other NIS map lookups, you'll need to define the + map as done in the below example. I have a "mailhosts" map, which I + use to distinguish between local and non-local hosts. Look at the + sendmail doc for details on this stuff. + + Kmailhosts nis -f -m -a. mailhosts + +5) You might wish to add the following line to support Errors-To: headers. + I don't. + + Ol + +6) Comment out/remove the following line: + + OR + + The R option means something different under v8 - check the documentation + if you're interested in using it. + +7) If you're running NIS and have a separate alias map, BELOW the + following line where the alias file is declared: + + OA/etc/aliases + + ADD the following: + + OAnis:mail.aliases + + This will set things up so v8 will look at the local alias DB first, + then the NIS map, just as Sun sendmail does. + +8) Though you don't have to, I'd suggest changing: + + OT3d + + to use v8's warning feature, which allows a warning message to be + sent if a message cannot be delivered within a specified period. + I use: + + OT5d/4h + + which says - bounce after 5 days, warn after 4 hours. + +9) I set the following option to be explicit about how I want DNS + handled: + + OI +DNSRCH +DEFNAMES + +10) The following line: + + T root daemon uucp + + may be deleted, though it will be ignored if you leave it around. + +11) It would probably be good to change the version macro value (which + shows up in "Received:" headers) so no one debugging mail problems + gets the wrong idea about what config you're running under. Look + for something like: + + DVSMI-4.1 + + Mine, for example is: + + DVADD-HUB-2.1 + + RULESETS + +1) In ruleset 3, BELOW this rule: + + # basic textual canonicalization + R$*<$+>$* $2 basic RFC822 parsing + + +I add the following rule to remove a trailing dot in the domain spec so +it won't interfere with v8 mapping features, etc. (Having a trailing dot is +not RFC-compliant anyway.): + + R$+. $1 + +2) Because ruleset 5 is special in v8, I rename it to S95 and also change + all RHS expressions containing ">5" to use ">95" instead. In v8, + 5 is executed against addresses which resolve to the local mailer and + are not an alias. If you don't change S5 to something else, you might + get a surprise! + +3) If you're doing any lookups via the generalized NIS "$%x/$!x" + mechanisms (such as with the mailhost map I referred to earlier) it's + done differently under v8. For example: + + DMmailhosts + ... + R$*<@$%M.uucp>$* $#ether $@$2 $:$1<@$2>$3 + + takes a different map definition and two rules under version 8: + + Kmailhosts nis -f -m -a. mailhosts + ... + R$*<@$+.uucp>$* $: $1<@$(mailhosts $2 $).uucp>$3 + R$*<@$+..uucp>$* $#ether $@$2 $:$1<@$2>$3 + +4) Sun has a special case of the "$%x" feature for host lookups - "%y" is + automagically defined to do an NIS "hosts.byname" search with no other + definition, as done in the below example: + + R$*<@$%y.LOCAL>$* $#ether $@$2 $:$1<@$2>$3 + + (Sun does this in more than one place. But the above syntax is almost + identical in each - mostly a case of changing names to protect the + innocent.) + + In version 8, the predefined "host" map can be used to do essentially + the same thing. (However, whether or not it does an NIS lookup is + a function of what gethostbyxxx() functions are linked in.) + + Recall the map definition I mentioned earlier in the DECLARATIONS + section: + + Khostlookup host -f -m -a. + + Here's where we will use it. It will take two rules: + + R$*<@$+.LOCAL>$* $: $1<@$(hostlookup $2 $).LOCAL>$3 + R$*<@$+..LOCAL>$* $#ether $@$2 $:$1<@$2>$3 + + Note that this is almost verbatim the same change as was used in the + previous "mailhosts" example. + +5) Although Sun's default configs don't do this, because I mentioned + canonicalization earlier, it deserves an example, as it's illustrative + of the functional difference in the map definitions I discussed before. + This stuff is also convered in the "Sendmail Installation and Operation + Guide". + + Remember the built-in "host" map definition? As you'll recall, unlike + the "hostlookup" map we defined, "host" will actually CHANGE the + hostname in addition to appending a dot. "hostlookup" only appends a + dot if the name is found and doesn't change it otherwise. Anyway, + here's the example: + + R$*<@$+>$* $: $1<@$(host $2 $)>$3 canonicalize + R$*<@$+.>$* $1<@$2>$3 remove trailing dot + + Using the above, say you had input of: + + joe<@tilde> + + OR + + joe<@[128.247.160.56]> + + Assuming "tilde" or the IP address is found, it might be + canonicalized as: + + joe<@tilde.csc.ti.com> + +6) As another instance of the NIS lookup feature, with a slightly + different twist, Sun implements reverse alias mapping in ruleset 22 + with the below: + + DZmail.byaddr + ... + R$-<@$-> $:$>3${Z$1@$2$} invert aliases + + To use this feature under v8, change the above rule a (remember to + define the alias map as I showed earlier): + + R$-<@$-> $:$>3$(aliasrev $1@$2 $) invert aliases + + + MAILER DEFINITIONS + +1) Where "TCP" is defined in the "P=" and "A=" parameters of mailers, I + changed it to "IPC". Version 8 will accept "TCP", but "IPC" is + preferred. + +2) On all IPC mailers, I also defined "E=\r\n" and added an "L=1000" as + in the below example: + + Mether, P=[IPC], F=mDFMuCX, S=11, R=21, L=1000, E=\r\n, A=IPC $h + + The "E=\r\n" will save you headaches interoperating with such things as + VMS TCP products. + + The "L=1000" is for RFC821 compatibility. Not strictly necessary. + + I also removed the "s" (strip quotes) mailer flag Sun puts in for + these mailers. Stripping quotes violates protocols, which say + clearly that you can't touch the local-part (left hand side of + the @) until you are on the delivering host. + +NOW. If I haven't left anything out, you should be able to run through +your Sun sendmail.cf file and convert it to run under v8. + + BUILD ISSUES + +Some important notes on building v8 on SunOS: + +Makefile + +The default makefile in the version 8 source (src) directory assumes the +new Berkeley make. Unless you want to go to the trouble of building it, +you can use your regular make, but you need to use a different makefile. +You can use "Makefile.dist" or "Makefile.SunOS" in the src directory. I +made changes to get it to build so it is as compatible as possible with +the file/directory locations Sun uses. Here are some relevant sections +out of my makefile: + + CC=gcc + + # use O=-O (usual) or O=-g (debugging) + O= -O + + # define the database mechanisms available for map & alias lookups: + # -DNDBM -- use new DBM + # -DNEWDB -- use new Berkeley DB + # -DNDBM -DNEWDB -DYPCOMPAT -- use both plus YP compatility + # -DNIS -- include client NIS support + # The really old (V7) DBM library is no longer supported. + # See READ_ME for a description of how these flags interact. + #DBMDEF= -DNDBM -DNEWDB + DBMDEF= -DNDBM -DNIS + + # environment definitions (e.g., -D_AIX3) + ENVDEF= + + # see also conf.h for additional compilation flags + + # library directories + LIBDIRS=-L/usr/local/lib + + # libraries required on your system + #LIBS= -ldb -ldbm + LIBS= -ldbm -lresolv + + # location of sendmail binary (usually /usr/sbin or /usr/lib) + BINDIR= ${DESTDIR}/usr/lib + + # location of sendmail.st file (usually /var/log or /usr/lib) + STDIR= ${DESTDIR}/etc + + # location of sendmail.hf file (usually /usr/share/misc or /usr/lib) + HFDIR= ${DESTDIR}/usr/lib + +For the resolver library, you can use the one shipped with Sun if you +want. But I'd recommend using another version of the resolver library +(such as the one with Bind 4.8.3 or 4.9). Sun's resolver stuff (at +least with 4.1.x) is quite old - I believe it is of 4.3.1 vintage. (Do +you get the impression I don't TRUST what Sun ships with their systems?) + +If you want NIS host lookup while maintaining DNS capability, you might +take a look at resolv+, which has NIS capable gethostbyxxx() functions +in it. My recommendation, however, is to avoid doing NIS host lookups +in sendmail altogether, and to use a "pure" version of the resolver +library. + +There are probably no situations (at least I think so) where it makes +any sense to link in Sun's NIS gethostbyxxx() functions from libc. +You could, I guess do it (I haven't tried it) and wind up with a +sendmail equivalent to the non-mx version Sun ships. You'd need to +insure that NAMED_BIND is not defined in the build. (If you do +this and have the "-b" DNS passthru option set in NIS, remember that +while you have some DNS functionality you'll not have any MX support. +(This, IMO, is what makes this a non-optimal choice.) + + INSTALLATION/TESTING ISSUES + +The sendmail.hf file in the src directory should replace the one currently +in /usr/lib. You also might choose to edit it a bit to "localize" what it +says. + +The sendmail executable goes, of course, in /usr/lib in place of the current +one. What I did was create a subdirectory in /usr/lib and put all of the +Sun sendmail stuff in there. I named the v8 sendmail executable to be +sendmail.v8.mx and then symbolically linked it to sendmail. + +One other thing. If you use address test mode, keep in mind that +Version 8 is like IDA in that it does not automatically execute ruleset +3 first. So say you're playing around with things testing addresses and +you're used to things like: + + 0 jimbob@good.old.boy.com + +under v8 you need to say instead: + + 3,0 jimbob@good.old.boy.com + + INTEROPERABILITY ISSUES YOU MIGHT ENCOUNTER + +Be aware that sendmail v8 issues a multi-line SMTP welcome (220) +response upon a client connection. Most systems in your network should +handle it OK, but there are some that choke on it, because whoever wrote +the clients assumed only a single line. THIS IS NOT SENDMAIL's FAULT. +A multi-line 220 response is perfectly valid. A likely place you'll +encounter this problem is with non-Un*x SMTP clients. If you do run +into it, you should report it to the vendor. + +A final note about version 8 - if you follow the above configuration +scenario, you'll notice it doesn't like to get envelope sender +addresses it doesn't know how to get back to. Sun sendmail would take +anything, even though it might not be able to bounce the message back +should something happen downstream. So if another sendmail on a host +that's not locally known is trying to pump mail through your v8 host, +the ENVELOPE sender it gives had better be fully qualified. This is +a GREAT thing, because it helps clear up problems we've had with not +being able to get things back to the sender, resulting in an +overburdened postmaster. + +I hope this helps those running Sun sendmail feel more at ease with moving +on to v8. It's really worth going to. diff --git a/usr.sbin/sendmail/contrib/expn.pl b/usr.sbin/sendmail/contrib/expn.pl index 4012699cac2f..15d287b5c650 100644 --- a/usr.sbin/sendmail/contrib/expn.pl +++ b/usr.sbin/sendmail/contrib/expn.pl @@ -1,10 +1,10 @@ #!/usr/local/bin/perl -'di'; -'ig00'; +'di '; +'ds 00 \\"'; +'ig00 '; +# # THIS PROGRAM IS ITS OWN MANUAL PAGE.

It doesn't matter + what version of sendmail you're running. It doesn't matter + if you're not running sendmail (but it won't fix anything + for you). + + 2) No configuration file hacks. If the -client switch is + absent (the default), the new sendmails will get an EHLO + using what LocalName() returns as the hostname. On my systems, + this returns the FQDN. If the EHLO fails with a result between + 500 and 599 and the -client switch is not set, we give up on + sending EHLO/HELO and just go deliver the mail. + + 3) No new configuration options. + + 4) Retains the undocumented -client switch. One warning: it + is possible using the -client switch to cause the old sendmails + to return "I refuse to talk to myself". You could do this under + the old code as well. This will happen if you claim to be the + same system as the sendmail you're sending to is running on. + That's pointless, but possible. If you do this, just like under + the old code, you will get an error. + + 5) If you're running a site with both old and new sendmails, you only + have to build MH once. The code's the same; works with them + both. + + If you decide to install this, make sure that you look the patch +over and that you agree with what it is doing. It works for me, but I +can't test it on every possible combination. Make sure that it works +before you really install it for your users, if any. No promises. + + To install this, save this to a file in the mts/sendmail directory. +Feed it to patch. Patch will ignore the non-patch stuff. You should have +"mts sendmail/smtp" in your configuration file. This works with old and +new sendmails. Using "mts sendmail" will cause the new sendmails to +print an "X-auth..." warning about who owns the process piping the mail +message. I don't know of anyway of getting rid of these. + + mh-config (if necessary), make, make inst-all. + + +I hope this helps people. + +/dcn + +Dave Nelson +Academic Computer Services +DePaul University, Chicago + +*** smail.c Fri Sep 3 11:58:05 1993 +--- smail.c Fri Sep 3 11:57:27 1993 +*************** +*** 239,261 **** + return RP_RPLY; + } + +! if (client && *client) { +! doingEHLO = 1; +! result = smtalk (SM_HELO, "EHLO %s", client); +! doingEHLO = 0; + +! if (500 <= result && result <= 599) + result = smtalk (SM_HELO, "HELO %s", client); +! +! switch (result) { + case 250: +! break; + + default: + (void) sm_end (NOTOK); + return RP_RPLY; + } + } + + #ifndef ZMAILER + if (onex) +--- 239,276 ---- + return RP_RPLY; + } + +! doingEHLO = 1; +! result = smtalk (SM_HELO, "EHLO %s", +!

These should +work with the version of make that is appropriate for that +system. + +There are a bunch of other Makefiles for other systems with names +like Makefile.HPUX for an HP-UX system. 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.

When used for alias files they interact in an +attempt to be back compatible. + +The three options are NEWDB (the new Berkeley DB package), NDBM (the +older DBM implementation -- the very old V7 implementation is no +longer supported), and NIS (Network Information Services). Used alone +these just include the support they indicate. [If you are using NEWDB, +get the latest version from FTP.CS.Berkeley.EDU in /ucb/4bsd. DO NOT +use the version from the Net2 distribution! However, if you are on +BSD/386 or 386BSD-based systems, use the one that already exists +on your system. You may need to define OLD_NEWDB to do this.] + +[NOTE WELL: it is CRITICAL that you remove ndbm.o from libdb.a and +ndbm.h from the appropriate include directories if you want to get +ndbm support. 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.] + +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. [Note however that +the NEWDB library also catches and maps NDBM calls; you will have to +back out this feature to get this to work. See ``Quirks'' section +below for details.] + +If all three are defined, sendmail operates as described above, and also +looks for the file /var/yp/Makefile. If it exists, newaliases will +build BOTH the NEWDB and NDBM format alias files. However, it will +only use the NEWDB file; the NDBM format file is used only by the +NIS subsystem. + +If NDBM and NIS are defined (regardless of the definition of NEWDB +or the existance of /var/yp/Makefile), 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 -DNEWDB, -DNDBM, and -DNIS are normally defined in the DBMDEF +line in the Makefile. + + ++---------------+ +| COMPILE FLAGS | ++---------------+ Whereever possible, I try to make sendmail pull in the correct compilation options needed to compile on various environments based on @@ -60,60 +178,158 @@ symbols availble, requiring the following compilation flags in the Makefile: SOLARIS Define this if you are running Solaris 2.0 or higher. -__NeXT__ Define this if you are on a NeXT box.

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.
