138032Speter SENDMAIL RELEASE NOTES 294334Sgshapiro $Id: RELEASE_NOTES,v 8.1296 2002/04/05 19:17:34 ca Exp $ 338032Speter 438032Speter 538032SpeterThis listing shows the version of the sendmail binary, the version 638032Speterof the sendmail configuration files, the date of release, and a 738032Spetersummary of the changes in that release. 838032Speter 994334Sgshapiro8.12.3/8.12.3 2002/04/05 1094334Sgshapiro NOTICE: In general queue files should not be moved if queue groups 1194334Sgshapiro are used. In previous versions this could cause mail 1294334Sgshapiro not to be delivered if a queue file is repeatedly moved 1394334Sgshapiro by an external process whenever sendmail moved it back 1494334Sgshapiro into the right place. Some precautions have been taken 1594334Sgshapiro to avoid moving queue files if not really necessary. 1694334Sgshapiro sendmail may use links to refer to queue files and it 1794334Sgshapiro may store the path of data files in queue files. Hence 1894334Sgshapiro queue files should not be moved unless those internals 1994334Sgshapiro are understood and the integrity of the files is not 2094334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 2194334Sgshapiro University. 2294334Sgshapiro If an error mail is created, and the mail is split across different 2394334Sgshapiro queue directories, and SuperSafe is off, then write the mail 2494334Sgshapiro to disk before splitting it, otherwise an assertion is 2594334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 2694334Sgshapiro of INTERMETA. 2794334Sgshapiro Fix possible race condition that could cause sendmail to forget 2894334Sgshapiro running queues. Problem noted by Jeff Wasilko of smoe.org. 2994334Sgshapiro Handle bogus qf files better without triggering assertions. 3094334Sgshapiro Problem noted by Guy Feltin. 3194334Sgshapiro Protect against interrupted select() call when enforcing Milter 3294334Sgshapiro read and write timeouts. Patch from Gurusamy Sarathy of 3394334Sgshapiro ActiveState. 3494334Sgshapiro Matching queue IDs with -qI should be case sensitive. Problem 3594334Sgshapiro noted by Anne Bennett of Concordia University. 3694334Sgshapiro If privileges have been dropped, don't try to change group ID to 3794334Sgshapiro the RunAsUser group. Problem noted by Neil Rickert of 3894334Sgshapiro Northern Illinois University. 3994334Sgshapiro Fix SafeFileEnvironment path munging when the specified path 4094334Sgshapiro contains a trailing slash. Based on patch from Dirk Meyer 4194334Sgshapiro of Dinoex. 4294334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 4394334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 4494334Sgshapiro Polytechnic Institute. 4594334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 4694334Sgshapiro if several mails are sent in one session and some of them 4794334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 4894334Sgshapiro Change timeout check such that cached information about a connection 4994334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 5094334Sgshapiro Based on patch from David Burns of Portland State University. 5194334Sgshapiro Properly count message size for mailstats during mail collection. 5294334Sgshapiro Problem noted by Werner Wiethege. 5394334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 5494334Sgshapiro patch from by Motonori Nakamura of Kyoto University. 5594334Sgshapiro Provide workaround for getopt() implementations that do not catch 5694334Sgshapiro missing arguments. 5794334Sgshapiro Fix the message size calculation if the message body is replaced by 5894334Sgshapiro a milter filter and buffered file I/O is being used. 5994334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 6094334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 6194334Sgshapiro Problem noted by Werner Wiethege. 6294334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 6394334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 6494334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 6594334Sgshapiro Properly deal with a case where sendmail is called by root running 6694334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 6794334Sgshapiro Lusky of ISS Atlanta. 6894334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 6994334Sgshapiro directories are used and mail is sent to a mailing list 7094334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 7194334Sgshapiro of Concordia University. 7294334Sgshapiro Fix class map parsing code if optional key is specified. Problem 7394334Sgshapiro found by Mario Nigrovic. 7494334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 7594334Sgshapiro incoming messages. A leading dot is always stripped by the 7694334Sgshapiro SMTP receiver regardless of whether or not it is followed by 7794334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 7894334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 7994334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 8094334Sgshapiro Elvers. 8194334Sgshapiro Correct the statistics gathered for total number of connections. 8294334Sgshapiro Instead of being the exact same number as the total number 8394334Sgshapiro of messages (T line in mailstats) it now represents the 8494334Sgshapiro total number of TCP connections. 8594334Sgshapiro Be more explicit about syntax errors in addresses, especially 8694334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 8794334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 8894334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 8994334Sgshapiro are used. Problem noted by Suresh Ramasubramanian. 9094334Sgshapiro Prevent a race condition on child cleanup for delivery to files. 9194334Sgshapiro Problem noted by Fletcher Mattox of the University of 9294334Sgshapiro Texas. 9394334Sgshapiro Change the SMTP error code for temporary map failures from 421 9494334Sgshapiro to 451. 9594334Sgshapiro Do not assume that realloc(NULL, size) works on all OS (this was 9694334Sgshapiro only done in one place: queue group creation). Based on 9794334Sgshapiro patch by Bryan Costales. 9894334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 9994334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 10094334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 10194334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 10294334Sgshapiro errors. By doing so, the host was marked as having a 10394334Sgshapiro temporary problem and other mail destined for that host was 10494334Sgshapiro queued for the next queue run. Problem noted by Fletcher 10594334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 10694334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 10794334Sgshapiro and Neil Rickert of Northern Illinois University. 10894334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 10994334Sgshapiro which drop the connection instead of responding to the 11094334Sgshapiro command). 11194334Sgshapiro Portability: 11294334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 11394334Sgshapiro availble. 11494334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 11594334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 11694334Sgshapiro settings. Patch from Elias Halldor Agustsson of 11794334Sgshapiro Skyrr. 11894334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 11994334Sgshapiro noted by John Beck. 12094334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 12194334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 12294334Sgshapiro Rajesh Somasund of Hewlett-Packard. 12394334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 12494334Sgshapiro SMTP AUTH information. This feature was actually added in 12594334Sgshapiro 8.12.0 but a release note was not included. 12694334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 12794334Sgshapiro parameter is set and the LDAP lookup returns a temporary 12894334Sgshapiro error. 12994334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 13094334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 13194334Sgshapiro Krzysztof Oledzki. 13294334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 13394334Sgshapiro initialization as aliases are not needed for the MSP. 13494334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 13594334Sgshapiro is in use. Patch from Andrzej Filip. 13694334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 13794334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 13894334Sgshapiro This will only have an effect if a parameter is specified, 13994334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 14094334Sgshapiro it is embedded in square brackets. Problem noted by 14194334Sgshapiro Theo Van Dinter of Collective Technologies. 14294334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 14394334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 14494334Sgshapiro to allow for the proper time zone on systems where the 14594334Sgshapiro default results in misleading time stamps. That is, syslog 14694334Sgshapiro time stamps and Date headers on submitted mail will use the 14794334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 14894334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 14994334Sgshapiro by Neil Rickert of Northern Illinois University. 15094334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 15194334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 15294334Sgshapiro noted by John Beck. 15394334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 15494334Sgshapiro if queue groups are used. 15594334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 15694334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 15794334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 15894334Sgshapiro Suggested by Bryan Costales. 15994334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 16094334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 16194334Sgshapiro structure that is passed to xxfi_connect(). Notice: 16294334Sgshapiro this fix requires that sendmail and libmilter have both 16394334Sgshapiro this change, mixing versions may lead to wrong port 16494334Sgshapiro values depending on the endianness of the involved systems. 16594334Sgshapiro Problem noted by Gisle Aas of ActiveState. 16694334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 16794334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 16894334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 16994334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 17094334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 17194334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 17294334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 17394334Sgshapiro this to 1 if your LDAP client libraries include 17494334Sgshapiro ldap_memfree(). 17594334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 17694334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 17794334Sgshapiro SMRSH: Fix compilation problem on some operating systems. Problem 17894334Sgshapiro noted by Christian Krackowizer of schuler technodat GmbH. 17994334Sgshapiro VACATION: Allow root to operate on user vacation databases. Based 18094334Sgshapiro on patch from Greg Couch of the University of California, 18194334Sgshapiro San Francisco. 18294334Sgshapiro VACATION: Don't ignore -C option. Based on patch by Bryan Costales. 18394334Sgshapiro VACATION: Clarify option usage in the man page. Problem noted by 18494334Sgshapiro Joe Barbish. 18594334Sgshapiro New Files: 18694334Sgshapiro libmilter/docs/smfi_setbacklog.html 18794334Sgshapiro 18890792Sgshapiro8.12.2/8.12.2 2002/01/13 18990792Sgshapiro Don't complain too much if stdin, stdout, or stderr are missing 19090792Sgshapiro at startup, only log an error message. 19190792Sgshapiro Fix potential problem if an unknown operation mode (character 19290792Sgshapiro following -b) has been specified. 19390792Sgshapiro Prevent purgestat from looping even if someone changes the 19490792Sgshapiro permissions or owner of hoststatus files. Problem noted 19590792Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 19690792Sgshapiro Properly record dropped connections in persistent host status. 19790792Sgshapiro Problem noted by Ulrich Windl of the Universitat 19890792Sgshapiro Regensburg. 19990792Sgshapiro Remove newlines from recipients read via sendmail -t to prevent 20090792Sgshapiro SMTP protocol errors when sending the RCPT command. 20190792Sgshapiro Problem noted by William D. Colburn of the New Mexico 20290792Sgshapiro Institute of Mining and Technology. 20390792Sgshapiro Only log milter body replacements once instead of for each body 20490792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 20590792Sgshapiro the Finnish Meteorological Institute. 20690792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 20790792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 20890792Sgshapiro of the Finnish Meteorological Institute. 20990792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 21090792Sgshapiro needs to collect children status to avoid zombie processes. 21190792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 21290792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 21390792Sgshapiro commands are issued. This makes it consistent with normal 21490792Sgshapiro SMTP connections. 21590792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 21690792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 21790792Sgshapiro and Technology. 21890792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 21990792Sgshapiro message sender if the sender had used a deprecated RFC822 22090792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 22190792Sgshapiro Meteorological Institute. 22290792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 22390792Sgshapiro parsing. Problem noted by Jorg Bielak from Coastal Web 22490792Sgshapiro Online. 22590792Sgshapiro For systems on which stat(2) does not return a value for st_blksize 22690792Sgshapiro that is the "optimal blocksize for I/O" three new compile 22790792Sgshapiro time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF, 22890792Sgshapiro and SM_IO_MAX_BUF, which define an upper limit for 22990792Sgshapiro regular files, and a lower and upper limit for other file 23090792Sgshapiro types, respectively. 23190792Sgshapiro Fix a potential deadlock if two events are supposed to occur at 23290792Sgshapiro exactly the same time. Problem noted by Valdis Kletnieks 23390792Sgshapiro of Virginia Tech. 23490792Sgshapiro Perform envelope splitting for aliases listed directly in the 23590792Sgshapiro alias file, not just for include/.forward files. 23690792Sgshapiro Problem noted by John Beck of Sun Microsystems. 23790792Sgshapiro Allow selection of queue group for mailq using -qGgroup. 23890792Sgshapiro Based on patch by John Beck of Sun Microsystems. 23990792Sgshapiro Make sure cached LDAP connections used my multiple maps in the same 24090792Sgshapiro process are closed. Patch from Taso N. Devetzis. 24190792Sgshapiro If running as root, allow reading of class files in protected 24290792Sgshapiro directories. Patch from Alexander Talos of the University 24390792Sgshapiro of Vienna. 24490792Sgshapiro Correct a few LDAP related memory leaks. Patch from David Powell 24590792Sgshapiro of Sun Microsystems. 24690792Sgshapiro Allow specification of an empty realm via the authinfo ruleset. 24790792Sgshapiro This is necessary to interoperate as an SMTP AUTH client 24890792Sgshapiro with servers that do not support realms when using 24990792Sgshapiro CRAM-MD5. Problem noted by Bjoern Voigt of TU Berlin. 25090792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 25190792Sgshapiro server gets stuck while processing that command. Problem 25290792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 25390792Sgshapiro In addition to printing errors when parsing recipients during 25490792Sgshapiro command line invocations log them to make it simpler 25590792Sgshapiro to understand possible DSNs to postmaster. 25690792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 25790792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 25890792Sgshapiro instead of forcing localhost. 25990792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 26090792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 26190792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 26290792Sgshapiro noted by Neil Rickert of Northern Illinois University. 26390792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 26490792Sgshapiro dropping the connection during an SMTP transaction, stop 26590792Sgshapiro sending commands. This prevents bogus "Bad file number" 26690792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 26790792Sgshapiro Worcester Polytechnic Institute. 26890792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 26990792Sgshapiro almost always too small; do not guess the size at all. 27090792Sgshapiro New VENDOR_DEC for Compaq/DEC. Requested by James Seagraves of 27190792Sgshapiro Compaq Computer Corp. 27290792Sgshapiro Fix DaemonPortOptions IPv6 address parsing such that ::1 works 27390792Sgshapiro properly. Problem noted by Valdis Kletnieks of Virginia 27490792Sgshapiro Tech. 27590792Sgshapiro Portability: 27690792Sgshapiro Fix IPv6 network interface probing on HP-UX 11.X. Based on 27790792Sgshapiro patch provided by HP. 27890792Sgshapiro Mac OS X (aka Darwin) has a broken setreuid() call, but a 27990792Sgshapiro working seteuid() call. From Daniel J. Luke. 28090792Sgshapiro Use proper type for a 32-bit integer on SINIX. From Ganu 28190792Sgshapiro Sachin of Siemens. 28290792Sgshapiro Set SM_IO_MIN_BUF (4K) and SM_IO_MAX_BUF (8K) for HP-UX. 28390792Sgshapiro Reduce optimization from +O3 to +O2 on HP-UX 11. This 28490792Sgshapiro fixes a problem that caused additional bogus 28590792Sgshapiro characters to be written to the qf file. Problem 28690792Sgshapiro noted by Tapani Tarvainen. 28790792Sgshapiro Set LDA_USE_LOCKF by default for UnixWare. Problem noted 28890792Sgshapiro by Boyd Lynn Gerber. 28990792Sgshapiro Add support for HP MPE/iX. See sendmail/README for port 29090792Sgshapiro information. From Mark Bixby of Hewlett-Packard. 29190792Sgshapiro New portability defines HASNICE, HASRRESVPORT, USE_ENVIRON, 29290792Sgshapiro USE_DOUBLE_FORK, and NEEDLINK. See sendmail/README 29390792Sgshapiro for more information. From Mark Bixby of 29490792Sgshapiro Hewlett-Packard. 29590792Sgshapiro If an OS doesn't have a method of finding free disk space 29690792Sgshapiro (SFS_NONE), lie and say there is plenty of space. 29790792Sgshapiro From Mark Bixby of Hewlett-Packard. 29890792Sgshapiro Add support for AIX 5.1.

From Hisanori Gogota 30190792Sgshapiro of the NTT/InterCommunication Center. 30290792Sgshapiro Do not assume that strerror() always returns a string. 30390792Sgshapiro Problem noted by John Beck of Sun Microsystems. 30490792Sgshapiro CONFIG: Add OSTYPE(freebsd5) for FreeBSD 5.X, which has removed 30590792Sgshapiro UUCP from the base operating system. From Mark Murray of 30690792Sgshapiro FreeBSD Services, Ltd. 30790792Sgshapiro CONFIG: Add OSTYPE(mpeix) and a generic .mc file for HP MPE/iX 30890792Sgshapiro systems. From Mark Bixby of Hewlett-Packard. 30990792Sgshapiro CONFIG: Add support for selecting a queue group for all mailers. 31090792Sgshapiro Based on proposal by Stephen L. Ulmer of the University of 31190792Sgshapiro Florida. 31290792Sgshapiro CONFIG: Fix error reporting for compat_check.m4. Problem noted by 31390792Sgshapiro Altin Waldmann. 31490792Sgshapiro CONFIG: Do not override user selections for confRUN_AS_USER and 31590792Sgshapiro confTRUSTED_USER in FEATURE(msp). From Mark Bixby of 31690792Sgshapiro Hewlett-Packard. 31790792Sgshapiro LIBMILTER: Fix bug that prevented the removal of a socket after 31890792Sgshapiro libmilter terminated. Problem reported by Andrey V. Pevnev 31990792Sgshapiro of MSFU. 32090792Sgshapiro LIBMILTER: Fix configuration error that required libsm for linking. 32190792Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 32290792Sgshapiro Institute. 32390792Sgshapiro LIBMILTER: Portability fix for OpenUNIX. Patch from Larry Rosenman. 32490792Sgshapiro LIBMILTER: Fix a theoretical memory leak and a possible attempt 32590792Sgshapiro to free memory twice. 32690792Sgshapiro LIBSM: Fix a potential segmentation violation in the I/O library. 32790792Sgshapiro Problem found and analyzed by John Beck and Tim Haley 32890792Sgshapiro of Sun Microsystems. 32990792Sgshapiro LIBSM: Do not clear the LDAP configuration information when 33090792Sgshapiro terminating the mailbox database connection in the LDAP 33190792Sgshapiro example code.

Add configuration options for 34790792Sgshapiro different set*gid() calls to reset saved gid. Problem 34890792Sgshapiro found by Michal Zalewski. 34990792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 35090792Sgshapiro privileges by disabling debugging (command line -d flag) 35190792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 35290792Sgshapiro used. Suggested by Michal Zalewski. 35390792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 35490792Sgshapiro Problem found by Michal Zalewski. 35590792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 35690792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 35790792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 35890792Sgshapiro If debugging is turned on (-d0.10) print not just the default 35990792Sgshapiro values for configuration file and pid file but also the 36090792Sgshapiro selected values. Problem noted by Brad Chapman. 36190792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 36290792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 36390792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 36490792Sgshapiro this only applied to hostname canonification. Problem 36590792Sgshapiro noted by Bill Fenner of AT&T Research. 36690792Sgshapiro Ignore comments in NIS host records when trying to find the 36790792Sgshapiro canonical name for a host. 36890792Sgshapiro When sendmail has extra privileges, limit mail submission command 36990792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 37090792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 37190792Sgshapiro suggestion from Michal Zalewski. 37290792Sgshapiro Portability: 37390792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 37490792Sgshapiro `uname` does not given complete information. 37590792Sgshapiro Problem noted by Keith Neufeld of the Cessna 37690792Sgshapiro Aircraft Company. 37790792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 37890792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 37990792Sgshapiro Avoid compiler warnings by not using pointers to pass 38090792Sgshapiro integers.

You need to create a new user and 41390792Sgshapiro a new group before installing sendmail (both called smmsp by 41490792Sgshapiro default). The installation process tries to install 41590792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 41690792Sgshapiro default. Please see sendmail/SECURITY for details. 41790792Sgshapiro SECURITY: Check for group and world writable forward and :include: 41890792Sgshapiro files.

Suggested 42790792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 42890792Sgshapiro (IdS). 42990792Sgshapiro Fixed problem of a global variable being used for a timeout jump 43090792Sgshapiro point where the variable could become overused for more than 43190792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 43290792Sgshapiro a corrupted stack causing a core dump. The timeout is now 43390792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 43490792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 43590792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 43690792Sgshapiro checks (group ID of RunAsUser). This allows use of a 43790792Sgshapiro set-group-ID sendmail binary for initial message submission 43890792Sgshapiro and no set-user-ID root sendmail is needed. For details 43990792Sgshapiro see sendmail/SECURITY. 44090792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 44190792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 44290792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 44390792Sgshapiro with a fallback of sendmail.cf as configuration file. See 44490792Sgshapiro sendmail/SECURITY. 44590792Sgshapiro New configuration file option UseMSP to allow group writable queue 44690792Sgshapiro files if the group is the same as that of a set-group-ID 44790792Sgshapiro sendmail binary. See sendmail/SECURITY. 44890792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 44990792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 45090792Sgshapiro is sendmail.cf (to be backward compatible). This selection 45190792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 45290792Sgshapiro file: client or mta). See sendmail/SECURITY. 45390792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 45490792Sgshapiro command has been removed. 45590792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 45690792Sgshapiro at compile time or per host (ruleset). 45790792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 45890792Sgshapiro used to look up local mail recipients; the default value 45990792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 46090792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 46190792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 46290792Sgshapiro long, to accomodate envelope splitting. File systems with 46390792Sgshapiro a 14 character file name length limit are no longer 46490792Sgshapiro supported. 46590792Sgshapiro Recipient list used for delivery now gets internally ordered by 46690792Sgshapiro hostsignature (character string version of MX RR). This orders 46790792Sgshapiro recipients for the same MX RR's together meaning smaller 46890792Sgshapiro portions of the list need to be scanned (instead of the whole 46990792Sgshapiro list) each delivery() pass to determine piggybacking. The 47090792Sgshapiro significance of the change is better the larger the recipient 47190792Sgshapiro list. Hostsignature is now created during recipient list 47290792Sgshapiro creation rather than just before delivery. 47390792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 47490792Sgshapiro piggybacking (called coincidental) extended to coattail 47590792Sgshapiro piggybacking. Rather than complete MX RR matching 47690792Sgshapiro (coincidental) piggybacking is done if just the lowest value 47790792Sgshapiro preference matches (coattail). 47890792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 47990792Sgshapiro try other MX hosts if available. 48090792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 48190792Sgshapiro outgoing (client-side) SMTP Authentication. 48290792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 48390792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 48490792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 48590792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 48690792Sgshapiro A new ruleset authinfo can be used to return client side 48790792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 48890792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 48990792Sgshapiro removed in future versions. 49090792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 49190792Sgshapiro requires 334. Mercury 1.48 is a known offender. 49290792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 49390792Sgshapiro for the security layer in SMTP AUTH (SASL). See 49490792Sgshapiro doc/op/op.me for details. 49590792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 49690792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 49790792Sgshapiro signed the presented certificate, the CN and the MD5 hash 49890792Sgshapiro of the presented certificate, respectively. 49990792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 50090792Sgshapiro New ruleset srv_features to enable/disable certain features in the 50190792Sgshapiro server per connection. See doc/op/op.me for details. 50290792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 50390792Sgshapiro recipient; useful to decide whether a conection is secure 50490792Sgshapiro enough on a per recipient basis. 50590792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 50690792Sgshapiro for STARTTLS. 50790792Sgshapiro If no certificate has been requested, the macro {verify} has the 50890792Sgshapiro value "NOT". 50990792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 51090792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 51190792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 51290792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 51390792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 51490792Sgshapiro really required. This change results in a noticable 51590792Sgshapiro performance gains on most machines. Moreover, if shared 51690792Sgshapiro memory is in use, reuse the key several times. 51790792Sgshapiro Add queue groups which can be used to group queue directories with 51890792Sgshapiro the same behavior together. See doc/op/op.me for details. 51990792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 52090792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 52190792Sgshapiro are initially sorted which may result in faster envelope 52290792Sgshapiro splitting. If the mail is submitted directly from the 52390792Sgshapiro command line, then the value also limits the number of 52490792Sgshapiro processes to deliver the envelopes; if more envelopes are 52590792Sgshapiro created they are only queued up and must be taken care of 52690792Sgshapiro by a queue run. 52790792Sgshapiro The check for 'enough disk space' now pays attention to which file 52890792Sgshapiro system each queue directory resides in. 52990792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 53090792Sgshapiro New option QueueFileMode for the default permissions of queue files. 53190792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 53290792Sgshapiro group (one or more queues in a multi-queue environment 53390792Sgshapiro collected together) to process the same work list at the 53490792Sgshapiro same time. 53590792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 53690792Sgshapiro active queue runner processes. 53790792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 53890792Sgshapiro runners per queue group. 53990792Sgshapiro Queue member selection by substring pattern matching now allows 54090792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 54190792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 54290792Sgshapiro of the queue that match during processing. 54390792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 54490792Sgshapiro periodically forking a child to process the queue, a single 54590792Sgshapiro child is forked for each queue that sleeps between queue 54690792Sgshapiro runs. A SIGHUP signal can be sent to restart this 54790792Sgshapiro persistent queue runner. 54890792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 54990792Sgshapiro sendmail process which only runs the queue at an interval: 55090792Sgshapiro sendmail -q15m). 55190792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 55290792Sgshapiro Proposed by Thom O'Connor. 55390792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 55490792Sgshapiro unless the new -qf option or -v is used. 55590792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 55690792Sgshapiro several queue runners are started by hand to avoid contention. 55790792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 55890792Sgshapiro of the qf file (older entries first). 55990792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 56090792Sgshapiro a client to specify an amount of time within which an e-mail 56190792Sgshapiro should be delivered. New option DeliverByMin added to set the 56290792Sgshapiro minimum amount of time or disable the extension. 56390792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 56490792Sgshapiro not allowed unless escaped or quoted. 56590792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 56690792Sgshapiro by Leif Johansson of Stockholm University, which was based on 56790792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 56890792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 56990792Sgshapiro Technology, Stockholm, Sweden. 57090792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 57190792Sgshapiro behavior (no MX lookups), put the name in square brackets. 57290792Sgshapiro Proposed by Thom O'Connor. 57390792Sgshapiro Use shared memory to store free space of filesystems that are used 57490792Sgshapiro for queues, if shared memory is available and if a key is set 57590792Sgshapiro via SharedMemoryKey. This minimizes the number of system 57690792Sgshapiro calls to check the available space. See doc/op/op.me for 57790792Sgshapiro details. 57890792Sgshapiro If shared memory is compiled in the option -bP can be used to print 57990792Sgshapiro the number of entries in the queue(s). 58090792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 58190792Sgshapiro and the usual documentation for details. 58290792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 58390792Sgshapiro Remove '-U' (initial user submission) command line option as 58490792Sgshapiro announced in 8.10. 58590792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 58690792Sgshapiro New macro {addr_type} which contains whether the current address is 58790792Sgshapiro an envelope sender or recipient address. Suggested by 58890792Sgshapiro Neil Rickert of Northern Illinois University. 58990792Sgshapiro Two new options for host maps: -d (retransmission timeout), 59090792Sgshapiro -r (number of retries). 59190792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 59290792Sgshapiro separator such that a lookup can return both an attribute 59390792Sgshapiro and value separated by the given separator. 59490792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 59590792Sgshapiro to map class arith. 59690792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 59790792Sgshapiro (errors that occur when sending an error message) are dropped. 59890792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 59990792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 60090792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 60190792Sgshapiro requirements for files containing secret keys. This is 60290792Sgshapiro necessary for the MSP if client authentification is used. 60390792Sgshapiro Properly handle quoted filenames for class files (to allow for 60490792Sgshapiro filenames with spaces). 60590792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 60690792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 60790792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 60890792Sgshapiro {if_addr_out} address of interface of outgoing connection. 60990792Sgshapiro {if_family_out} family of interface of outgoing connection. 61090792Sgshapiro The latter two are only set if the interface does not belong 61190792Sgshapiro to the loopback net. 61290792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 61390792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 61490792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 61590792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 61690792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 61790792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 61890792Sgshapiro all connections for a single delivery attempt to succeed. 61990792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 62090792Sgshapiro a threshold number of recipients has been rejected (option 62190792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 62290792Sgshapiro Development Group. 62390792Sgshapiro New option DelayLA to delay connections if the load averages 62490792Sgshapiro exceeds the specified value. The default of 0 does not 62590792Sgshapiro change the previous behavior. A value greater than 0 62690792Sgshapiro will cause sendmail to sleep for one second on most 62790792Sgshapiro SMTP commands and before accepting connections if that 62890792Sgshapiro load average is exceeded. 62990792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 63090792Sgshapiro recipients that are sent during a connection to a mailer. 63190792Sgshapiro This also introduces a new mailer field 'r' which defines 63290792Sgshapiro the maximum number of recipients (defaults to 100). 63390792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 63490792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 63590792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 63690792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 63790792Sgshapiro instead. 63890792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 63990792Sgshapiro builtin mailer pathnames. Use TCP instead. 64090792Sgshapiro PH map code updated to use the new libphclient API instead of the 64190792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 64290792Sgshapiro University of Illinois at Urbana-Champaign. 64390792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 64490792Sgshapiro for direct (command line) submissions. 64590792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 64690792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 64790792Sgshapiro Hagino of the KAME Project. 64890792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 64990792Sgshapiro whose content is rewritten similar to Reply-To:. 65090792Sgshapiro Proposed by Andrzej Filip. 65190792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 65290792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 65390792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 65490792Sgshapiro AUTH/STARTTLS related logfile entries. 65590792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 65690792Sgshapiro before logging. 65790792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 65890792Sgshapiro (at LogLevel 9/10 or higher). 65990792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 66090792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 66190792Sgshapiro in which most commands are rejected due to check_relay or 66290792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 66390792Sgshapiro Change logging format for cloned envelopes to be similar to that for 66490792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 66590792Sgshapiro of the Universitat Regensburg. 66690792Sgshapiro Added libsm, a C library of general purpose abstractions including 66790792Sgshapiro assertions, tracing and debugging with named debug categories, 66890792Sgshapiro exception handling, malloc debugging, resource pools, 66990792Sgshapiro portability abstractions, and an extensible buffered I/O 67090792Sgshapiro package. It will at some point replace libsmutil. 67190792Sgshapiro See libsm/index.html for details. 67290792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 67390792Sgshapiro care of by fork() and exit(). 67490792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 67590792Sgshapiro more consistent portablity amongst different platforms 67690792Sgshapiro new and old (from new libsm). 67790792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 67890792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 67990792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 68090792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 68190792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 68290792Sgshapiro synchronizations calls. 68390792Sgshapiro Add per-recipient status information to mailq -v output. 68490792Sgshapiro T_ANY queries are no longer used by sendmail. 68590792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 68690792Sgshapiro too (see include/sm/cdefs.h for more info). 68790792Sgshapiro sendmail -d now has general support for named debug categories. 68890792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 68990792Sgshapiro for details. 69090792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 69190792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 69290792Sgshapiro generated by this condition were illegal (not RFC conform). 69390792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 69490792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 69590792Sgshapiro mailer and the recipient has hence been rejected during the 69690792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 69790792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 69890792Sgshapiro that do not have postmaster defined. If an email was sent 69990792Sgshapiro from an address to which a DSN cannot be returned and 70090792Sgshapiro in which at least one recipient address is non-deliverable, 70190792Sgshapiro then that email had been delivered in each queue run. 70290792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 70390792Sgshapiro degli Studi dell'Insubria. 70490792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 70590792Sgshapiro i.e., the corresponding code is always compiled in now. 70690792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 70790792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 70890792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 70990792Sgshapiro attempting to canonify a hostname, some broken nameservers 71090792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 71190792Sgshapiro lookups. If you want to excuse this behavior, use this new 71290792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 71390792Sgshapiro Mark Roth of the University of Illinois at 71490792Sgshapiro Urbana-Champaign. 71590792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 71690792Sgshapiro noted by Joy Latten of IBM. 71790792Sgshapiro ConnectionRateThrottle limits the number of connections per second 71890792Sgshapiro to each daemon individually, not the overall number of 71990792Sgshapiro connections. 72090792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 72190792Sgshapiro sendmail to use a default alias schema as outlined in the 72290792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 72390792Sgshapiro cf/README. 72490792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 72590792Sgshapiro the first character after the class name is not a '/' or a 72690792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 72790792Sgshapiro rest of the line will be parsed as a map lookup. This 72890792Sgshapiro allows classes to be filled via a map lookup. See op.me 72990792Sgshapiro for more syntax information. Specifically, this can be 73090792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 73190792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 73290792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 73390792Sgshapiro example). 73490792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 73590792Sgshapiro the default schema used in the above two items. 73690792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 73790792Sgshapiro warning if a program being run from a mailer or file class 73890792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 73990792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 74090792Sgshapiro if a program being run from a mailer or file class 74190792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 74290792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 74390792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 74490792Sgshapiro (without quotes) will disable this and return to the 74590792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 74690792Sgshapiro Suggested by Bryan Stansell of GNAC. 74790792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 74890792Sgshapiro HELO/EHLO commands. 74990792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 75090792Sgshapiro possible protocol family which may be used for outgoing 75190792Sgshapiro connections. Restrictions placed on one family only affect 75290792Sgshapiro outgoing connections on that particular family. Because of 75390792Sgshapiro this change, the ${client_flags} macro is not set until the 75490792Sgshapiro connection is established. Based on patch from Motonori 75590792Sgshapiro Nakamura of Kyoto University. 75690792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 75790792Sgshapiro when the -bv option is given by users who are neither root 75890792Sgshapiro nor the TrustedUser so users can not read private aliases, 75990792Sgshapiro forwards, or :include: files. It also will override the -v 76090792Sgshapiro (verbose) command line option. 76190792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 76290792Sgshapiro address can't be used for the outgoing connection, fall 76390792Sgshapiro back to the settings in ClientPortOptions (if set). 76490792Sgshapiro Problem noted by John Beck of Sun Microsystems. 76590792Sgshapiro New named config file rule check_data for DATA command (input: 76690792Sgshapiro number of recipients). Based on patch from Mark Roth of 76790792Sgshapiro the University of Illinois at Urbana-Champaign. 76890792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 76990792Sgshapiro can be specified using the '#' option character. For 77090792Sgshapiro example, 'ETRN #queuegroup'. 77190792Sgshapiro If an LDAP server times out or becomes unavailable, close the 77290792Sgshapiro current connection and reopen to get to one of the fallback 77390792Sgshapiro servers. Patch from Paul Hilchey of the University of 77490792Sgshapiro British Columbia. 77590792Sgshapiro Make default error number on $#error messages 550 instead of 501 77690792Sgshapiro because 501 is not allowed on all commands. 77790792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 77890792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 77990792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 78090792Sgshapiro if required. 78190792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 78290792Sgshapiro class instead. 78390792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 78490792Sgshapiro "IPv6:" tag to identify the address properly. For example, 78590792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 78690792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 78790792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 78890792Sgshapiro MTA is running. For example, during a queue run. 78990792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 79090792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 79190792Sgshapiro Nelson of IBM. 79290792Sgshapiro The maximum number of commands before the MTA slows down when too 79390792Sgshapiro many "light weight" commands have been received are now 79490792Sgshapiro configurable during compile time. The current values and 79590792Sgshapiro their defaults are: 79690792Sgshapiro MAXBADCOMMANDS 25 unknown commands 79790792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 79890792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 79990792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 80090792Sgshapiro MAXETRNCOMMANDS 8 ETRN 80190792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 80290792Sgshapiro Costales of SL3D, Inc. 80390792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 80490792Sgshapiro ${MyMacro} is defined but also that it is not empty. 80590792Sgshapiro Properly quote usernames with special characters if they are used 80690792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 80790792Sgshapiro Meteorological Institute. 80890792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 80990792Sgshapiro messages for messages for mailing list expanded addresses 81090792Sgshapiro which are not delivered on the initial attempt. 81190792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 81290792Sgshapiro the final dot has been sent to avoid affecting future 81390792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 81490792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 81590792Sgshapiro file systems that require to call fsync() for a directory 81690792Sgshapiro if the meta-data in it has been changed. This should be 81790792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 81890792Sgshapiro See sendmail/README for further information. 81990792Sgshapiro Avoid file locking deadlock when updating the statistics file if 82090792Sgshapiro sendmail is signaled to terminate. Problem noted by 82190792Sgshapiro Christophe Wolfhugel of France Telecom. 82290792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 82390792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 82490792Sgshapiro the Finnish Meteorological Institute. 82590792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 82690792Sgshapiro from Peter A. Friend of EarthLink. 82790792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 82890792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 82990792Sgshapiro flora.ca. 83090792Sgshapiro Portability: 83190792Sgshapiro Remove support for AIX 2, which supports only 14 character 83290792Sgshapiro filenames and is outdated anyway. Suggested by 83390792Sgshapiro Valdis Kletnieks of Virginia Tech. 83490792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 83590792Sgshapiro i.e., use default /usr/sbin, change owner/group 83690792Sgshapiro of man pages and user-executable to root/sys, set 83790792Sgshapiro optimization limit to 0 (unlimited). Based on patch 83890792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 83990792Sgshapiro Hurtta of the Finnish Meteorological Institute. 84090792Sgshapiro Do not assume LDAP support is installed by default under 84190792Sgshapiro Solaris 8 and later. 84290792Sgshapiro Add support for OpenUNIX. 84390792Sgshapiro CONFIG: Increment version number of config file to 10. 84490792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 84590792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 84690792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 84790792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 84890792Sgshapiro temporary lookup failures. 84990792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 85090792Sgshapiro action to be taken by aborting the search for domain names 85190792Sgshapiro or IP nets. 85290792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 85390792Sgshapiro relay address as long as the other part allows the email 85490792Sgshapiro to get through. 85590792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 85690792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 85790792Sgshapiro entry like user+*@domain. This allows handling of details by 85890792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 85990792Sgshapiro introduced to match only non-empty details of addresses. 86090792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 86190792Sgshapiro and hence there is no required order within the MAILER 86290792Sgshapiro section anymore except for MAILER(`uucp') which must come 86390792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 86490792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 86590792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 86690792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 86790792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 86890792Sgshapiro in the access map which returns OK or RELAY actually 86990792Sgshapiro terminates check_* ruleset checking. 87090792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 87190792Sgshapiro tls_rcpt, see cf/README for details. 87290792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 87390792Sgshapiro STARTTLS has been used to "(version=${tls_version} 87490792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 87590792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 87690792Sgshapiro options friends/haters instead of "To:" and enable 87790792Sgshapiro specification of whole domains instead of just users. 87890792Sgshapiro Notice: this change is not backward compatible. 87990792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 88090792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 88190792Sgshapiro cf/README for details. 88290792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 88390792Sgshapiro the access map. Proposed by Randall Winchester of the 88490792Sgshapiro University of Maryland. 88590792Sgshapiro CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for 88690792Sgshapiro the local mailer. Proposed by Ingo Brueckl of Wupper Online. 88790792Sgshapiro CONFIG: confRELAY_MSG/confREJECT_MSG can override the default 88890792Sgshapiro messages for an unauthorized relaying attempt/for access 88990792Sgshapiro map entries with RHS REJECT, respectively. 89090792Sgshapiro CONFIG: FEATURE(`always_add_domain') takes an optional argument 89190792Sgshapiro to specify another domain to be added instead of the local one. 89290792Sgshapiro Suggested by Richard H. Gumpertz of Computer Problem 89390792Sgshapiro Solving. 89490792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 89590792Sgshapiro options, see doc/op/op.me for details. 89690792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 89790792Sgshapiro the security layer in SMTP AUTH (SASL). 89890792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 89990792Sgshapiro immediately. 90090792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 90190792Sgshapiro allows checking of the return values of the DNS lookups. 90290792Sgshapiro See cf/README for details. 90390792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 90490792Sgshapiro temporary lookup failures. 90590792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 90690792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 90790792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 90890792Sgshapiro memory use. 90990792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 91090792Sgshapiro of the sender and the recipient address delimited by the 91190792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 91290792Sgshapiro in the access map. Based on code contributed by Mathias 91390792Sgshapiro Koerber of Singapore Telecommunications Ltd. 91490792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 91590792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 91690792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 91790792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 91890792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 91990792Sgshapiro the recipient host if LUSER_RELAY is used. 92090792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 92190792Sgshapiro +detail portion of the address when passing address to 92290792Sgshapiro local delivery agent. Disables alias and .forward +detail 92390792Sgshapiro stripping. Only use if LDA supports this. 92490792Sgshapiro CONFIG: Removed deprecated FEATURE(`rbl'). 92590792Sgshapiro CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() 92690792Sgshapiro which allow you to specify 'equivalent' hosts for LDAP 92790792Sgshapiro Routing lookups. Equivalent hostnames are replaced by the 92890792Sgshapiro masquerade domain name for lookups. See cf/README for 92990792Sgshapiro additional details. 93090792Sgshapiro CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which 93190792Sgshapiro instructs the rulesets on what to do if the address being 93290792Sgshapiro looked up has +detail information. See cf/README for more 93390792Sgshapiro information. 93490792Sgshapiro CONFIG: When chosing a new destination via LDAP Routing, also look 93590792Sgshapiro up the new routing address/host in the mailertable.

Miller of Courtesan Consulting. 126073188Sgshapiro Unixware 7.1.1 doesn't allow h_errno to be set directly if 126173188Sgshapiro sendmail is being compiled with -kthread. Problem 126273188Sgshapiro noted by Orion Poplawski of CQG, Inc. 126373188Sgshapiro CONTRIB: buildvirtuser: Substitute current domain for $DOMAIN and 126473188Sgshapiro current left hand side for $LHS in virtuser files. 126573188Sgshapiro DEVTOOLS: Do not pass make targets to recursive Build invocations. 126673188Sgshapiro Problem noted by Jeff Bronson of J.D. Bronson, Inc. 126773188Sgshapiro MAIL.LOCAL: In LMTP mode, do not return errors regarding problems 126873188Sgshapiro storing the temporary message file until after the remote 126973188Sgshapiro side has sent the final DATA termination dot. Problem 127073188Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic 127173188Sgshapiro Institute. 127273188Sgshapiro MAIL.LOCAL: If LMTP mode is set, give a temporary error if users 127373188Sgshapiro are also specified on the command line. Patch from 127473188Sgshapiro Motonori Nakamura of Kyoto University. 127573188Sgshapiro PRALIASES: Skip over AliasFile specifications which aren't based on 127673188Sgshapiro database files (i.e., only show dbm, hash, and btree). 127773188Sgshapiro Renamed Files: 127873188Sgshapiro devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x 127973188Sgshapiro 128071345Sgshapiro8.11.2/8.11.2 2000/12/29 128171345Sgshapiro Prevent a segmentation fault when trying to set a class in 128271345Sgshapiro address test mode due to a negative array index. Audit 128371345Sgshapiro other array indexing. This bug is not believed to be 128471345Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 128571345Sgshapiro Schools" project (IdS). 128671345Sgshapiro Add an FFR (for future release) to drop privileges when using 128771345Sgshapiro address test mode. This will be turned on in 8.12. It can 128871345Sgshapiro be enabled by compiling with: 128971345Sgshapiro APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS') 129071345Sgshapiro in your devtools/Site/site.config.m4 file. Suggested by 129171345Sgshapiro Michal Zalewski of the "Internet for Schools" project (IdS). 129271345Sgshapiro Fix potential problem with Cyrus-SASL security layer which may have 129371345Sgshapiro caused I/O errors, especially for mechanism DIGEST-MD5. 129471345Sgshapiro When QueueSortOrder was set to host, sendmail might not read 129571345Sgshapiro enough of the queue file to determine the host, making the 129671345Sgshapiro sort sub-optimal. Problem noted by Jeff Earickson of 129771345Sgshapiro Colby College. 129871345Sgshapiro Don't issue DSNs for addresses which use the NOTIFY parameter (per 129971345Sgshapiro RFC 1891) but don't have FAILURE as value. 130071345Sgshapiro Initialize Cyrus-SASL library before the SMTP daemon is started. 130171345Sgshapiro This implies that every change to SASL related files requires 130271345Sgshapiro a restart of the daemon, e.g., Sendmail.conf, new SASL 130371345Sgshapiro mechanisms (in form of shared libraries). 130471345Sgshapiro Properly set the STARTTLS related macros during a queue run for 130571345Sgshapiro a cached connection. Bug reported by Michael Kellen of 130671345Sgshapiro NxNetworks, Inc. 130771345Sgshapiro Log the server name in relay= for ruleset tls_server instead of the 130871345Sgshapiro client name. 130971345Sgshapiro Include original length of bad field/header when reporting 131071345Sgshapiro MaxMimeHeaderLength problems. Requested by Ulrich Windl of 131171345Sgshapiro the Universitat Regensburg. 131271345Sgshapiro Fix delivery to set-user-ID files that are expanded from aliases in 131371345Sgshapiro DeliveryMode queue.

Patch from 132571345Sgshapiro Jun-ichiro itojun Hagino of the KAME Project. 132671345Sgshapiro Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish 132771345Sgshapiro Meteorological Institute. 132871345Sgshapiro Fix parsing of DaemonPortOptions and ClientPortOptions. Read all 132971345Sgshapiro of the parameters to find Family= setting before trying to 133071345Sgshapiro interpret Addr= and Port=. Problem noted by Valdis 133171345Sgshapiro Kletnieks of Virginia Tech. 133271345Sgshapiro When delivering to a file directly from an alias, do not call 133371345Sgshapiro initgroups(); instead use the DefaultUser group information. 133471345Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 133571345Sgshapiro RunAsUser now overrides the ownership of the control socket, if 133671345Sgshapiro created. Otherwise, sendmail can not remove it upon 133771345Sgshapiro close. Problem noted by Werner Wiethege. 133871345Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 133971345Sgshapiro overall connections, not the number of connections per 134071345Sgshapiro socket. A future version may change this to per socket 134171345Sgshapiro counting. 134271345Sgshapiro Portability: 134371345Sgshapiro Clean up libsmdb so it functions properly on platforms 134471345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t).

Problem noted by Motonori Nakamura 138271345Sgshapiro of Kyoto University. 138371345Sgshapiro RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It 138471345Sgshapiro causes some changes in behavior and may break rmail for 138571345Sgshapiro installations where sendmail is actually a wrapper to 138671345Sgshapiro another MTA. The change will re-appear in a future 138771345Sgshapiro version. 138871345Sgshapiro SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X, 138971345Sgshapiro and SunOS 5.8.

Problem noted by Marc G. 143166494Sgshapiro Fournier of Acadia University. 143266494Sgshapiro If an LDAP search fails because the LDAP server went down, close 143366494Sgshapiro the map so subsequent searches reopen the map. If there are 143466494Sgshapiro multiple LDAP servers, the down server will be skipped and 143566494Sgshapiro one of the others may be able to take over. 143666494Sgshapiro Set the ${load_avg} macro to the current load average, not the 143766494Sgshapiro previous load average query result. 143866494Sgshapiro If a non-optional map used in a check_* ruleset can't be opened, 143966494Sgshapiro return a temporary failure to the remote SMTP client 144066494Sgshapiro instead of ignoring the map. Problem noted by Allan E 144166494Sgshapiro Johannesen of Worcester Polytechnic Institute. 144266494Sgshapiro Avoid a race condition when queuing up split envelopes by saving 144366494Sgshapiro the split envelopes before the original envelope. 144466494Sgshapiro Fix a bug in the PH_MAP code which caused mail to bounce instead of 144566494Sgshapiro defer if the PH server could not be contacted. From Mark 144666494Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 144766494Sgshapiro Prevent QueueSortOrder=Filename from interfering with -qR, -qS, and 144866494Sgshapiro ETRN.

If sendmail needs to drop 151364562Sgshapiro these privileges and the operating system doesn't set the 151464562Sgshapiro saved-uid as well, exit with an error. Problem noted by 151564562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 151664562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 151764562Sgshapiro it populates. It is possible that some broken 151864562Sgshapiro implementations of snprintf() exist that do not do this. 151964562Sgshapiro Systems in this category should compile with 152064562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 152164562Sgshapiro system and report broken implementations to 152264562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 152364562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 152464562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 152564562Sgshapiro Implementation influenced by the example programs of 152664562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 152764562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 152864562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 152964562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 153064562Sgshapiro cf/README and doc/op/op.*. 153164562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 153264562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 153364562Sgshapiro ${server_name}, and ${server_addr}. These are documented 153464562Sgshapiro in cf/README and doc/op/op.*. 153564562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 153664562Sgshapiro random data. 153764562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 153864562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 153964562Sgshapiro try to use STARTTLS despite the security problems. 154064562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 154164562Sgshapiro support encryption. Based on code contributed by Tim 154264562Sgshapiro Martin of CMU. 154364562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 154464562Sgshapiro strength factor. 154564562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 154664562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 154764562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 154864562Sgshapiro of CMU. 154964562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 155064562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 155164562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 155264562Sgshapiro Fix the default family selection for DaemonPortOptions. As 155364562Sgshapiro documented, unless a family is specified in a 155464562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 155564562Sgshapiro also the default if no DaemonPortOptions value is set. 155664562Sgshapiro Therefore, IPv6 users should configure additional sockets 155764562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 155864562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 155964562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 156064562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 156164562Sgshapiro the interface information for an outgoing connection. 156264562Sgshapiro Not doing so was creating a mismatch between the socket 156364562Sgshapiro family and address used in subsequent connections if the 156464562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 156564562Sgshapiro by John Beck of Sun Microsystems. 156664562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 156764562Sgshapiro family based on the IP address. ${if_family} is no longer 156864562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 156964562Sgshapiro of Sun Microsystems. 157064562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 157164562Sgshapiro macros for both the incoming interface address/family and 157264562Sgshapiro the outgoing interface address/family. In order for M=b 157364562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 157464562Sgshapiro the incoming information in the queue file for later 157564562Sgshapiro delivery attempts. 157664562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 157764562Sgshapiro responses to commands.

Problem noted by Ari Heikkinen of Pohjois-Savo 160264562Sgshapiro Polytechnic. 160364562Sgshapiro Under the proper circumstances, failed connections would be recorded 160464562Sgshapiro as "Bad file number" instead of "Connection failed" in the 160564562Sgshapiro queue file and persistent host status. Problem noted by 160664562Sgshapiro Graeme Hewson of Oracle. 160764562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 160864562Sgshapiro within the hoststatus directory (e.g., lost+found). 160964562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 161064562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 161164562Sgshapiro sender.

Problem noted by Michal Zalewski of the 188464562Sgshapiro "Internet for Schools" project (IdS). 188564562Sgshapiro SECURITY: There is a potential for a denial of service attack if 188664562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 188764562Sgshapiro sendmail process while it is rebuilding the aliases file 188864562Sgshapiro (leaving it in an inconsistent state). This option and 188964562Sgshapiro its use is deprecated and will be removed from a future 189064562Sgshapiro version of sendmail. 189164562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 189264562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 189364562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 189464562Sgshapiro (IdS). 189564562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 189664562Sgshapiro a large number of files. See cf/README for more details. 189764562Sgshapiro The directory structure of the distribution has changed slightly 189864562Sgshapiro for easier code sharing among the programs. 189964562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 190064562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 190164562Sgshapiro which hold the client's authentication credentials, 190264562Sgshapiro the mechanism used for authentication, and the 190364562Sgshapiro authorization identity (i.e., the AUTH= parameter if 190464562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 190564562Sgshapiro On systems which use the Torek stdio library (all of the BSD 190664562Sgshapiro distributions), use memory-buffered files to reduce 190764562Sgshapiro file system overhead by not creating temporary files on 190864562Sgshapiro disk. Contributed by Exactis.com, Inc. 190964562Sgshapiro New option DataFileBufferSize to control the maximum size of a 191064562Sgshapiro memory-buffered data (df) file before a disk-based file is 191164562Sgshapiro used. Contributed by Exactis.com, Inc. 191264562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 191364562Sgshapiro memory-buffered transcript (xf) file before a disk-based 191464562Sgshapiro file is used. Contributed by Exactis.com, Inc. 191564562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 191664562Sgshapiro now listen on several different ports. Use: 191764562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 191864562Sgshapiro to run a Message Submission Agent (MSA); this is turned 191964562Sgshapiro on by default in m4-generated .cf files; it can be turned 192064562Sgshapiro off with FEATURE(`no_default_msa'). 192164562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 192264562Sgshapiro begin using RFC 2476 Message Submission for initial user 192364562Sgshapiro message submission. XUSR may disappear from a future release. 192464562Sgshapiro The new '-G' (relay (gateway) submission) command line option 192564562Sgshapiro indicates that the message being submitted from the command 192664562Sgshapiro line is for relaying, not initial submission. This means 192764562Sgshapiro the message will be rejected if the addresses are not fully 192864562Sgshapiro qualified and no canonicalization will be done. Future 192964562Sgshapiro releases may even reject improperly formed messages. 193064562Sgshapiro The '-U' (initial user submission) command line option is 193164562Sgshapiro deprecated and may be removed from a future release. 193264562Sgshapiro Mail user agents should begin using '-G' to indicate that 193364562Sgshapiro this is a relay submission (the inverse of -U). 193464562Sgshapiro The next release of sendmail will assume that any message submitted 193564562Sgshapiro from the command line is an initial user submission and act 193664562Sgshapiro accordingly. 193764562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 193864562Sgshapiro program or deliver to file as the owner of that file, the 193964562Sgshapiro address is marked as unsafe. This means if RunAsUser is 194064562Sgshapiro set, users won't be able to use programs or delivery to 194164562Sgshapiro files in their .forward files. Administrators can override 194264562Sgshapiro this by setting the DontBlameSendmail option to the new 194364562Sgshapiro setting NonRootSafeAddr. 194464562Sgshapiro Allow group or world writable directories if the sticky bit is set 194564562Sgshapiro on the directory and DontBlameSendmail is set to 194664562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 194764562Sgshapiro InCert Software. 194864562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 194964562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 195064562Sgshapiro set in the DontBlameSendmail option. Requested by many. 195164562Sgshapiro New Timeout.control option to limit the total time spent satisfying 195264562Sgshapiro a control socket request. 195364562Sgshapiro New Timeout.resolver options for controlling BIND resolver 195464562Sgshapiro settings: 195564562Sgshapiro Timeout.resolver.retrans 195664562Sgshapiro Sets the resolver's retransmission time interval (in 195764562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 195864562Sgshapiro and Timeout.resolver.retrans.normal. 195964562Sgshapiro Timeout.resolver.retrans.first 196064562Sgshapiro Sets the resolver's retransmission time interval (in 196164562Sgshapiro seconds) for the first attempt to deliver a message. 196264562Sgshapiro Timeout.resolver.retrans.normal 196364562Sgshapiro Sets the resolver's retransmission time interval (in 196464562Sgshapiro seconds) for all resolver lookups except the first 196564562Sgshapiro delivery attempt. 196664562Sgshapiro Timeout.resolver.retry 196764562Sgshapiro Sets the number of times to retransmit a resolver 196864562Sgshapiro query. Sets both Timeout.resolver.retry.first 196964562Sgshapiro and Timeout.resolver.retry.normal. 197064562Sgshapiro Timeout.resolver.retry.first 197164562Sgshapiro Sets the number of times to retransmit a resolver 197264562Sgshapiro query for the first attempt to deliver a message. 197364562Sgshapiro Timeout.resolver.retry.normal 197464562Sgshapiro Sets the number of times to retransmit a resolver 197564562Sgshapiro query for all resolver lookups except the first 197664562Sgshapiro delivery attempt. 197764562Sgshapiro Contributed by Exactis.com, Inc. 197864562Sgshapiro Support multiple queue directories. To use multiple queues, supply 197964562Sgshapiro a QueueDirectory option value ending with an asterisk. For 198064562Sgshapiro example, /var/spool/mqueue/q* will use all of the 198164562Sgshapiro directories or symbolic links to directories beginning with 198264562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 198364562Sgshapiro mind, the queue directory structure should not be changed 198464562Sgshapiro while sendmail is running. Queue runs create a separate 198564562Sgshapiro process for running each queue unless the verbose flag is 198664562Sgshapiro given on a non-daemon queue run. New items are randomly 198764562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 198864562Sgshapiro Support different directories for qf, df, and xf queue files; if 198964562Sgshapiro subdirectories or symbolic links to directories of those names 199064562Sgshapiro exist in the queue directories, they are used for the 199164562Sgshapiro corresponding queue files. Keep in mind, the queue 199264562Sgshapiro directory structure should not be changed while sendmail is 199364562Sgshapiro running. Proposed by Mathias Koerber of Singapore 199464562Sgshapiro Telecommunications Ltd. 199564562Sgshapiro New queue file naming system which uses a filename guaranteed to be 199664562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 199764562Sgshapiro without fancy file system locking. Queued items can be 199864562Sgshapiro moved between queues easily. Contributed by Exactis.com, 199964562Sgshapiro Inc. 200064562Sgshapiro Messages which are undeliverable due to temporary address failures 200164562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 200264562Sgshapiro set. Contributed by Exactis.com, Inc. 200364562Sgshapiro New command line option '-L tag' which sets the identifier used for 200464562Sgshapiro syslog. Contributed by Exactis.com, Inc. 200564562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 200664562Sgshapiro avoids opening and reading each queue file when preparing 200764562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 200864562Sgshapiro Shared memory counters and microtimers functionality has been 200964562Sgshapiro donated by Exactis.com, Inc. 201064562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 201164562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 201264562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 201364562Sgshapiro being added. Suggested by Michael K. Sanders. 201464562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 201564562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 201664562Sgshapiro and John Beck of Sun Microsystems. 201764562Sgshapiro In low-disk space situations, where sendmail would previously refuse 201864562Sgshapiro connections, still accept them, but only allow ETRN commands. 201964562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 202064562Sgshapiro Ltd. 202164562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 202264562Sgshapiro on systems which support them. This can be used with LMTP 202364562Sgshapiro local delivery agents which listen on a named socket. An 202464562Sgshapiro example mailer might be: 202564562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 202664562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 202764562Sgshapiro A=FILE /var/run/lmtpd 202864562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 202964562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 203064562Sgshapiro instead. 203164562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 203264562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 203364562Sgshapiro connections), IPC (which will be deprecated in a future 203464562Sgshapiro version), and FILE (for UNIX domain socket delivery). 203564562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 203664562Sgshapiro flags. 203764562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 203864562Sgshapiro body of the original message on delivery status 203964562Sgshapiro notifications. 204064562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 204164562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 204264562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 204364562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 204464562Sgshapiro Steve Schweinhart of America Online. 204564562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 204664562Sgshapiro not be set after rulesets are defined. Suggested by 204764562Sgshapiro Mitchell Blank Jr of Exec-PC. 204864562Sgshapiro Do not report temporary failure on delivery to files. In 204964562Sgshapiro interactive delivery mode, this would result in two SMTP 205064562Sgshapiro responses after the DATA command. Problem noted by 205164562Sgshapiro Nik Conwell of Boston University. 205264562Sgshapiro Check file close when mailing to files. Problem noted by Nik 205364562Sgshapiro Conwell of Boston University. 205464562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 205564562Sgshapiro Curtis W. Hillegas of Princeton University. 205664562Sgshapiro Always bind to the LDAP server regardless of whether you are using 205764562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 205864562Sgshapiro @Home Network. 205964562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 206064562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 206164562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 206264562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 206364562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 206464562Sgshapiro similar to check_rcpt etc. 206564562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 206664562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 206764562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 206864562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 206964562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 207064562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 207164562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 207264562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 207364562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 207464562Sgshapiro the corresponding DSN parameter values. Proposed by 207564562Sgshapiro Mathias Herberts. 207664562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 207764562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 207864562Sgshapiro before the message has been collected, thereafter it holds 207964562Sgshapiro the message size as computed by sendmail (and can be used 208064562Sgshapiro in check_compat). 208164562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 208264562Sgshapiro sendmail is using instead of the value of the DeliveryMode 208364562Sgshapiro option. 208464562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 208564562Sgshapiro Drop explicit From: if same as what would be generated only if it is 208664562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 208764562Sgshapiro Write pid to file also if sendmail only processes the queue. 208864562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 208964562Sgshapiro Log "low on disk space" only when necessary. 209064562Sgshapiro New macro ${load_avg} can be used to check the current load average. 209164562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 209264562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 209364562Sgshapiro is set. 209464562Sgshapiro Flag -S for maps to specify the character which is substituted 209564562Sgshapiro for spaces (instead of the default given by O BlankSub). 209664562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 209764562Sgshapiro This flag is set by default for the host map. Based on a 209864562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 209964562Sgshapiro Open maps only on demand, not at startup. 210064562Sgshapiro Log warning about unsupported IP address families. 210164562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 210264562Sgshapiro of the sum of all headers. This can be used to prevent 210364562Sgshapiro a denial-of-service attack. 210464562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 210564562Sgshapiro headers and parameters within those headers. This option 210664562Sgshapiro is intended to protect mail user agents from buffer 210764562Sgshapiro overflow attacks. 210864562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 210964562Sgshapiro alias recursion. 211064562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 211164562Sgshapiro Map type syslog to log the key via syslogd. 211264562Sgshapiro Entries in the alias file can be continued by putting a backslash 211364562Sgshapiro directly before the newline. 211464562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 211564562Sgshapiro dead.letter file, formerly hardcoded to 211664562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 211764562Sgshapiro default), sendmail will not attempt to save to a 211864562Sgshapiro system-wide dead.letter file if it can not bounce the mail 211964562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 212064562Sgshapiro file as it has in the past when the dead.letter file 212164562Sgshapiro could not be opened. 212264562Sgshapiro New option PidFile to define the location of the pid file. The 212364562Sgshapiro value of this option is macro expanded. 212464562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 212564562Sgshapiro process title shown in 'ps' listings. 212664562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 212764562Sgshapiro (along with the already existing macros): 212864562Sgshapiro ${daemon_info} Daemon information, e.g. 212964562Sgshapiro SMTP+queueing@00:30:00 213064562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 213164562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 213264562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 213364562Sgshapiro ${daemon_port} Daemon port, e.g., 25 213464562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 213564562Sgshapiro New macros especially for virtual hosting: 213664562Sgshapiro ${if_name} hostname of interface of incoming connection. 213764562Sgshapiro ${if_addr} address of interface of incoming connection. 213864562Sgshapiro The latter is only set if the interface does not belong to the 213964562Sgshapiro loopback net. 214064562Sgshapiro If a message being accepted via a method other than SMTP and 214164562Sgshapiro would be rejected by a header check, do not send the message. 214264562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 214364562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 214464562Sgshapiro Provide header value as quoted string in the macro 214564562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 214664562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 214764562Sgshapiro The length of the header value is stored in ${hdrlen}. 214864562Sgshapiro H*: allows to specify a default ruleset for header checks. This 214964562Sgshapiro ruleset will only be called if the individual header does 215064562Sgshapiro not have its own ruleset assigned. Suggested by Jan 215164562Sgshapiro Krueger of Unix-AG of University of Hannover. 215264562Sgshapiro The name of the header field stored in ${hdr_name}. 215364562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 215464562Sgshapiro removed if the config file version is greater than or equal 215564562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 215664562Sgshapiro input "token (1)" but does not match "token". 215764562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 215864562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 215964562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 216064562Sgshapiro Ericsson. 216164562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 216264562Sgshapiro messages with 8-bit text in headers. Problem noted by 216364562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 216464562Sgshapiro of Ericsson. 216564562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 216664562Sgshapiro modified database map file. Problem noted by Chris Adams 216764562Sgshapiro of Renaissance Internet Services. 216864562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 216964562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 217064562Sgshapiro queue up the message instead of bouncing it. 217164562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 217264562Sgshapiro standard does not provide any indication of what to do when 217364562Sgshapiro something other than 250 is received. Based on a patch 217464562Sgshapiro from Steve Schweinhart of America Online. 217564562Sgshapiro New option TrustedUser allows to specify a user who can own 217664562Sgshapiro important files instead of root. This requires HASFCHOWN. 217764562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 217864562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 217964562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 218064562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 218164562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 218264562Sgshapiro $? tests also whether the macro is non-null. 218364562Sgshapiro Print an error message if a mailer definition contains an invalid 218464562Sgshapiro equate name. 218564562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 218664562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 218764562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 218864562Sgshapiro mailer to return after sending all data to it. 218964562Sgshapiro Only free memory from the process list when adding a new process 219064562Sgshapiro into a previously filled slot. Previously, the memory was 219164562Sgshapiro freed at removal time. Since removal can happen in a 219264562Sgshapiro signal handler, this may leave the memory map in an 219364562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 219464562Sgshapiro David Cooley of Colby College. 219564562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 219664562Sgshapiro local users in the passwd file. The UserDB code has 219764562Sgshapiro already decided the message will be passed to another host 219864562Sgshapiro for processing. Fix from Tony Landells of Burdett 219964562Sgshapiro Buckeridge Young Limited. 220064562Sgshapiro Support LDAP authorization via either a file containing the 220164562Sgshapiro password or Kerberos V4 using the new map options 220264562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 220364562Sgshapiro distinguished_name is who to login as. The method can be 220464562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 220564562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 220664562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 220764562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 220864562Sgshapiro of Stanford University. 220964562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 221064562Sgshapiro deprecated and will be removed in a future version. 221164562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 221264562Sgshapiro and the map has the column delimiter set, it turns that 221364562Sgshapiro response into a delimiter separated string. The LDAP map 221464562Sgshapiro will traverse multiple entries as well. LDAP alias maps 221564562Sgshapiro automatically set the column delimiter to the comma. 221664562Sgshapiro Based on patch from Booker Bense of Stanford University and 221764562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 221864562Sgshapiro Support return of multiple values for a single LDAP lookup. The 221964562Sgshapiro values to be returned should be in a comma separated string. 222064562Sgshapiro For example, `-v "email,emailother"'. Patch from 222164562Sgshapiro Curtis W. Hillegas of Princeton University. 222264562Sgshapiro Allow the use of LDAP for alias maps. 222364562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 222464562Sgshapiro attributes found in the match will be returned. 222564562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 222664562Sgshapiro breaking up a single entry into multiple entries. This is 222764562Sgshapiro needed for LDAP alias file specifications to allow for 222864562Sgshapiro comma separated key and value strings. 222964562Sgshapiro Keep connections to LDAP server open instead of opening and closing 223064562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 223164562Sgshapiro connections such that multiple maps which use the same 223264562Sgshapiro host, port, bind DN, and authentication will only result in 223364562Sgshapiro a single connection to that host. 223464562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 223564562Sgshapiro Be more careful about checking for errors and freeing memory on 223664562Sgshapiro LDAP lookups. 223764562Sgshapiro Use asynchronous LDAP searches to save memory and network 223864562Sgshapiro resources. 223964562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 224064562Sgshapiro Increase portability to the Netscape LDAP libraries. 224164562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 224264562Sgshapiro replaced with the literal contents of the map lookup key -- 224364562Sgshapiro note that this means a lookup can be done using the LDAP 224464562Sgshapiro special characters. The new '%0' token can be used instead 224564562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 224664562Sgshapiro For example, if the LDAP map specification contains '-k 224764562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 224864562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 224964562Sgshapiro user attribute. Instead, if the LDAP map specification 225064562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 225164562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 225264562Sgshapiro with the name "*". 225364562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 225464562Sgshapiro more than one is returned, it is equivalent to no records 225564562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 225664562Sgshapiro alias dereference option; "-Z size" limits the number of 225764562Sgshapiro matches to return. 225864562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 225964562Sgshapiro LDAP maps. The value should only contain LDAP specific 226064562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 226164562Sgshapiro settings will be used for all LDAP maps unless they are 226264562Sgshapiro specified in the individual map specification ('K' 226364562Sgshapiro command). This option should be set before any LDAP maps 226464562Sgshapiro are defined. 226564562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 226664562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 226764562Sgshapiro Tech. 226864562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 226964562Sgshapiro particular, class entries get much smaller, which can be 227064562Sgshapiro important if you have large classes. 227164562Sgshapiro On network-related temporary failures, record the hostname which 227264562Sgshapiro gave error in the queued status message. Requested by 227364562Sgshapiro Ulrich Windl of the Universitat Regensburg. 227464562Sgshapiro Add new F=% mailer flag to allow for a store and forward 227564562Sgshapiro configuration. Mailers which have this flag will not attempt 227671345Sgshapiro delivery on initial receipt of a message or on queue runs 227764562Sgshapiro unless the queued message is selected using one of the 227864562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 227964562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 228064562Sgshapiro New option ControlSocketName which, when set, creates a daemon 228164562Sgshapiro control socket. This socket allows an external program to 228264562Sgshapiro control and query status from the running sendmail daemon 228364562Sgshapiro via a named socket, similar to the ctlinnd interface to the 228464562Sgshapiro INN news server. Access to this interface is controlled by 228564562Sgshapiro the UNIX file permissions on the named socket on most UNIX 228664562Sgshapiro systems (see sendmail/README for more information). An 228764562Sgshapiro example control program is provided as contrib/smcontrol.pl. 228864562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 228964562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 229064562Sgshapiro number of processors online on the system (if that can be 229164562Sgshapiro determined). For single processor machines, this change 229264562Sgshapiro has no effect. 229364562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 229464562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 229564562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 229664562Sgshapiro Motonori Nakamura of Kyoto University. 229764562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 229864562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 229964562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 230064562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 230164562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 230264562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 230364562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 230464562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 230564562Sgshapiro connection-based denial of service attacks. 230664562Sgshapiro Log basic information about authenticated connections at LogLevel 230764562Sgshapiro 10 or higher. 230864562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 230964562Sgshapiro information (from= syslog line). 231064562Sgshapiro Log the DSN code for each recipient if one is available as a new 231164562Sgshapiro equate (dsn=). 231264562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 231364562Sgshapiro New "ph" map for performing ph queries in rulesets.

Problem noted by Kari Hurtta of the 231964562Sgshapiro Finnish Meteorological Institute. 232064562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 232164562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 232264562Sgshapiro When a forward file points to an alias which runs a program, run 232364562Sgshapiro the program as the default user and the default group, not 232464562Sgshapiro the forward file user. This change also assures the 232564562Sgshapiro :include: directives in aliases are also processed using 232664562Sgshapiro the default user and group. Problem noted by Sergiu 232764562Sgshapiro Popovici of DNT Romania. 232864562Sgshapiro Prevent attempts to save a dead.letter file for a user with 232964562Sgshapiro no home directory (/no/such/directory). Problem noted by 233064562Sgshapiro Michael Brown of Finnigan FT/MS. 233164562Sgshapiro Include message delay and number of tries when logging that a 233264562Sgshapiro message has been completely delivered (LogLevel of 10 or 233364562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 233464562Sgshapiro Log the sender of a message even if none of the recipients were 233564562Sgshapiro accepted. If some of the recipients were rejected, it is 233664562Sgshapiro helpful to know the sender of the message. 233764562Sgshapiro Check the root directory (/) when checking a path for safety. 233864562Sgshapiro Problem noted by John Beck of Sun Microsystems. 233964562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 234064562Sgshapiro interactive and delivering to an alias which resolves to 234164562Sgshapiro multiple files. 234264562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 234364562Sgshapiro greater (see below); the help function doesn't print the 234464562Sgshapiro version of sendmail any longer, instead it is placed in 234564562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 234664562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 234764562Sgshapiro skipped and a version line (#vers) is introduced. The 234864562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 234964562Sgshapiro version is found, a warning is logged. The '#vers' 235064562Sgshapiro directive should be placed at the top of the help file. 235164562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 235264562Sgshapiro disk succeeded. Suggested by Nick Christenson. 235364562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 235464562Sgshapiro length before the attempt. 235564562Sgshapiro If a forward points to a filename for delivery, change to the 235664562Sgshapiro user's uid before checking permissions on the file. This 235764562Sgshapiro allows delivery to files on NFS mounted directories where 235864562Sgshapiro root is remapped to nobody. Problem noted by Harald 235964562Sgshapiro Daeubler of Universitaet Ulm. 236064562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 236164562Sgshapiro host status files, not all files. 236264562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 236364562Sgshapiro in the queue file for the message and set when delivery 236464562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 236564562Sgshapiro Wonderworks Inc. 236664562Sgshapiro Add support for storing information between rulesets using the new 236764562Sgshapiro macro map class. This can be used to store information 236864562Sgshapiro between queue runs as well using $={persistentMacros}. 236964562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 237064562Sgshapiro of Hannover. 237164562Sgshapiro New map class arith to allow for computations in rules. The 237264562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 237364562Sgshapiro as key. The two operands are specified as arguments; the 237464562Sgshapiro lookup returns the result of the computation. For example, 237564562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 237664562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 237764562Sgshapiro Add new syntax for header declarations which decide whether to 237864562Sgshapiro include the header based on a macro rather than a mailer 237964562Sgshapiro flag: 238064562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 238164562Sgshapiro This should be used along with $={persistentMacros}. 238264562Sgshapiro It can be used for adding headers to a message based on 238364562Sgshapiro the results of check_* and header check rulesets. 238464562Sgshapiro Allow new named config file rule check_eoh which is called after 238564562Sgshapiro all of the headers have been collected. The input to the 238664562Sgshapiro ruleset the number of headers and the size of all of the 238764562Sgshapiro headers in bytes separated by $|. This ruleset along with 238864562Sgshapiro the macro storage map can be used to correlate information 238964562Sgshapiro gathered between headers and to check for missing headers. 239064562Sgshapiro See cf/README or doc/op/op.ps for an example. 239164562Sgshapiro Change the default for the MeToo option to True to correspond 239264562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 239364562Sgshapiro option is deprecated and will be removed from a future 239464562Sgshapiro version. 239564562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 239664562Sgshapiro Change the sendmail binary default for SuperSafe to True. 239764562Sgshapiro Display ruleset names in debug and address test mode output 239864562Sgshapiro if referencing a named ruleset. 239964562Sgshapiro New mailer equate m= which will limit the number of messages 240064562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 240164562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 240264562Sgshapiro using it to sort. Now all the same domains are really run 240364562Sgshapiro through the queue together. If they have the same MX host, 240464562Sgshapiro then they will have a much better opportunity to use the 240564562Sgshapiro connection cache if available. This should be a reasonable 240664562Sgshapiro performance improvement. Patch from Randall Winchester of 240764562Sgshapiro the University of Maryland. 240864562Sgshapiro If a message is rejected by a header check ruleset, log who would 240964562Sgshapiro have received the message if it had not been rejected. 241064562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 241164562Sgshapiro queue immediately. No delivery attempt is made. 241264562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 241364562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 241464562Sgshapiro COMMANDS). 241564562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 241664562Sgshapiro but for outgoing connections. 241764562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 241864562Sgshapiro error messages and logging) and Modifiers, i.e. 241964562Sgshapiro a require authentication 242064562Sgshapiro b bind to interface through which mail has 242164562Sgshapiro been received 242264562Sgshapiro c perform hostname canonification 242364562Sgshapiro f require fully qualified hostname 242464562Sgshapiro h use name of interface for outgoing HELO 242564562Sgshapiro command 242664562Sgshapiro C don't perform hostname canonification 242764562Sgshapiro E disallow ETRN (see RFC 2476) 242864562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 242964562Sgshapiro h use name of interface for HELO command 243064562Sgshapiro The version number for queue files (qf) has been incremented to 4. 243164562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 243264562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 243364562Sgshapiro Institutes of Health. 243464562Sgshapiro If a mailer dies, print the status in decimal instead of octal 243564562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 243664562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 243764562Sgshapiro Move message priority from sender to recipient logging. Suggested by 243864562Sgshapiro Ulrich Windl of the Universitat Regensburg. 243964562Sgshapiro Add support for Berkeley DB 3.X. 244064562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 244164562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 244264562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 244364562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 244464562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 244564562Sgshapiro sub-options is set on the command line. Problem noted by 244664562Sgshapiro Graeme Hewson of Oracle. 244764562Sgshapiro Randomize equal preference MX records each time delivery is 244864562Sgshapiro attempted via a new connection to a host instead of once per 244964562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 245064562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 245164562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 245264562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 245364562Sgshapiro to hosts which have dynamically assigned names. 245464562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 245564562Sgshapiro the bounce for the same reason. If the body is not 8-bit 245664562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 245764562Sgshapiro not be included in the bounce. Problem noted by Valdis 245864562Sgshapiro Kletnieks of Virginia Tech. 245964562Sgshapiro The timeout for sending a message via SMTP has been changed from 246064562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 246164562Sgshapiro simply checks for progress on sending data every 5 minutes. 246264562Sgshapiro This will detect the inability to send information quicker 246364562Sgshapiro and reduce the number of processes simply waiting to 246464562Sgshapiro timeout. 246564562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 246664562Sgshapiro interface address structure when loading the system network 246764562Sgshapiro interface addresses.

Problem noted by Per 258664562Sgshapiro Hedeland of Ericsson. 258764562Sgshapiro mailq displays unprintable characters in addresses as their octal 258864562Sgshapiro representation and a leading backslash. This avoids problems 258964562Sgshapiro with "unprintable" characters. Problem noted by Michal 259064562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 259164562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 259264562Sgshapiro one character past the limit. This would cause subsequent 259364562Sgshapiro hops to break the line again. The '!' is now placed in 259464562Sgshapiro the last column of the limit if the line needs to be broken. 259564562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 259664562Sgshapiro from Per Hedeland of Ericsson. 259764562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 259864562Sgshapiro resolver will fall back to TCP. However, some 259964562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 260064562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 260164562Sgshapiro don't fail on ANY queries. 260264562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 260364562Sgshapiro address, do not send an empty postmaster notification DSN 260464562Sgshapiro to the postmaster.

Suggested by Joe Pruett 278464562Sgshapiro of Q7 Enterprises. 278564562Sgshapiro CONFIG: MASQUERADE_EXCEPTION() defines hosts/subdomains which 278664562Sgshapiro will not be masqueraded. Proposed by Arne Wichmann 278764562Sgshapiro of MPI Saarbruecken, Griff Miller of PGS Tensor, 278864562Sgshapiro Jayme Cox of Broderbund Software Inc. 278964562Sgshapiro CONFIG: A list of exceptions for FEATURE(`nocanonify') can be 279064562Sgshapiro specified by CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE, 279164562Sgshapiro i.e., a list of domains which are passed to $[ ... $] 279264562Sgshapiro for canonification. Based on an idea from Neil Rickert 279364562Sgshapiro of Northern Illinois University. 279464562Sgshapiro CONFIG: If `canonify_hosts' is specified as parameter for 279564562Sgshapiro FEATURE(`nocanonify') then addresses which have only 279664562Sgshapiro a hostname, e.g., <user@host>, will be canonified. 279764562Sgshapiro CONFIG: If FEATURE(`nocanonify') is turned on, a trailing dot is 279864562Sgshapiro nevertheless added to addresses with more than one component 279964562Sgshapiro in it. 280064562Sgshapiro CONFIG: Canonification is no longer attempted for any host or domain 280164562Sgshapiro in class 'P' ($=P). 280264562Sgshapiro CONFIG: New class for matching virtusertable entries $={VirtHost} that 280364562Sgshapiro can be populated by VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE. 280464562Sgshapiro FEATURE(`virtuser_entire_domain') can be used to apply this 280564562Sgshapiro class also to entire subdomains. Hosts in this class are 280664562Sgshapiro treated as canonical in SCanonify2, i.e., a trailing dot 280764562Sgshapiro is added. 280864562Sgshapiro CONFIG: If VIRTUSER_DOMAIN() or VIRTUSER_DOMAIN_FILE() are used, 280964562Sgshapiro include $={VirtHost} in $=R (hosts allowed to relay). 281064562Sgshapiro CONFIG: FEATURE(`generics_entire_domain') can be used to apply the 281164562Sgshapiro genericstable also to subdomains of $=G. 281264562Sgshapiro CONFIG: Pass "+detail" as %2 for virtusertable lookups. 281364562Sgshapiro Patch from Noam Freedman from University of Chicago. 281464562Sgshapiro CONFIG: Pass "+detail" as %1 for genericstable lookups. Suggested 281564562Sgshapiro by Raymond S Brand of rsbx.net. 281664562Sgshapiro CONFIG: Allow @domain in genericstable to override masquerading. 281764562Sgshapiro Suggested by Owen Duffy from Owen Duffy & Associates. 281864562Sgshapiro CONFIG: LOCAL_DOMAIN() adds entries to class w. Suggested by Steve 281964562Sgshapiro Hubert of University of Washington. 282064562Sgshapiro CONFIG: OSTYPE(`gnuhurd') has been replaced by OSTYPE(`gnu') as 282164562Sgshapiro GNU is now the canonical system name.

Prindeville of Enteka Enterprise Technology 282964562Sgshapiro Services. 283064562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 283164562Sgshapiro names. Problem noted by Randall Winchester of Swales 283264562Sgshapiro Aerospace. 283364562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 283464562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 283564562Sgshapiro University and Brian Candler. 283664562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 283764562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 283864562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 283964562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 284064562Sgshapiro Institute. 284164562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 284264562Sgshapiro i.e., to set, add, or delete flags. 284364562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 284464562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 284564562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 284664562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 284764562Sgshapiro after check_rcpt and allows for exceptions from the checks. 284864562Sgshapiro CONFIG: Map declarations have been moved into their associated 284964562Sgshapiro feature files to allow greater flexibility in use of 285064562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 285164562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 285264562Sgshapiro line string for the local mailer. Requested by Il Oh of 285364562Sgshapiro Willamette Industries, Inc. 285464562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 285564562Sgshapiro converted to <user@d> 285664562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 285764562Sgshapiro Sun's older, broken configuration files. 285864562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 285964562Sgshapiro normal configuration, allowing anti-spam checks to be 286064562Sgshapiro performed. 286164562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 286264562Sgshapiro ${client_name} can't be resolved just temporarily. 286364562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 286464562Sgshapiro Institute. 286564562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 286664562Sgshapiro be accessed by their numbers). 286764562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 286864562Sgshapiro which describes whether to disallow "!" in the local part 286964562Sgshapiro of an address. 287064562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 287164562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 287264562Sgshapiro set. If the ruleset returns a mailer, the appropriate 287364562Sgshapiro action is taken, otherwise the returned tokens are ignored. 287464562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 287564562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 287664562Sgshapiro The latter is kept around for backward compatibility. 287764562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 287864562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 287964562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 288064562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 288164562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 288264562Sgshapiro Institute. 288364562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 288464562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 288564562Sgshapiro arguments overriding the mailer program, arguments, and 288664562Sgshapiro mailer definition flags. This makes it possible to use 288764562Sgshapiro other programs such as maildrop for local delivery. 288864562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 288964562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 289064562Sgshapiro Patch from Richard A. Nelson of IBM. 289164562Sgshapiro CONFIG: Add SMTP Authentication information to Received: header 289264562Sgshapiro default value (confRECEIVED_HEADER). 289364562Sgshapiro CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a 289464562Sgshapiro local mailer. Problem noted by Per Hedeland of Ericsson. 289564562Sgshapiro CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the 289664562Sgshapiro University of California at Berkeley. 289764562Sgshapiro CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of 289864562Sgshapiro Illinois at Urbana-Champaign. 289964562Sgshapiro CONTRIB: etrn.pl now recognizes bogus host names.

Problem noted by Ezequiel H. Panepucci of 290664562Sgshapiro Yale University. 290764562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 290864562Sgshapiro be used for building. 290964562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 291064562Sgshapiro used for a fresh build. 291164562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 291264562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 291364562Sgshapiro ranlib. 291464562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 291564562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 291664562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 291764562Sgshapiro building of the man pages when defined. Suggested by Bryan 291864562Sgshapiro Costales. 291964562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 292064562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 292164562Sgshapiro installation of the sendmail helpfile and statistics file 292264562Sgshapiro respectively. Suggested by Bryan Costales. 292364562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 292464562Sgshapiro of Siemens Business Services. 292564562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 292664562Sgshapiro stdio library. The new buffered file I/O depends on the 292764562Sgshapiro Torek stdio library. This option can be either portable or 292864562Sgshapiro torek. 292964562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 293064562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 293164562Sgshapiro They should contain the C source files for the object files 293264562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 293364562Sgshapiro will be passed to the 'make depend' stage of compilation. 293464562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 293564562Sgshapiro in the sendmail distribution. Each has the form 293664562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 293764562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 293864562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 293964562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 294064562Sgshapiro building the distribution, but documentation on the changes 294164562Sgshapiro are in devtools/README. 294264562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 294364562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 294464562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 294564562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 294664562Sgshapiro new variable which identifies the root of the source 294764562Sgshapiro directories for all of the programs in the distribution. 294864562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 294964562Sgshapiro time. They can both still be overridden by setting the m4 295064562Sgshapiro macro. 295164562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 295264562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 295364562Sgshapiro build configurations, and places objects in obj.prefix.*/. 295464562Sgshapiro Complains as 'Build -f file' does for existing object 295564562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 295664562Sgshapiro Corporation. 295764562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 295864562Sgshapiro manual pages in the directory tree specified by 295964562Sgshapiro confMANROOTMAN. 296064562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 296164562Sgshapiro preformatted pages from the distribution. The new variable 296264562Sgshapiro confCOPY specifies the copying program. 296364562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 296464562Sgshapiro question. Suggested by Terry Lambert of Whistle 296564562Sgshapiro Communications. 296664562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 296764562Sgshapiro of the installed statistics and help files, respectively. 296864562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 296964562Sgshapiro operating system identity. Problem noted by Erik 297064562Sgshapiro Wachtenheim of Dartmouth College. 297164562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 297264562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 297364562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 297464562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 297564562Sgshapiro how to strip binaries. These are used by the new 297664562Sgshapiro install-strip target. 297764562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 297864562Sgshapiro the others (if it exists). 297964562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 298064562Sgshapiro then the default ones. 298190792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 298264562Sgshapiro as local delivery agent without LMTP mode, use 298364562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 298464562Sgshapiro to set the S flag. 298564562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 298664562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 298764562Sgshapiro Northern Illinois University. 298864562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 298964562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 299064562Sgshapiro the Finnish Meteorological Institute. 299164562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 299264562Sgshapiro MAILLOCK when compiling. Also requires linking with 299364562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 299464562Sgshapiro University. 299564562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 299664562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 299764562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 299864562Sgshapiro University. 299964562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 300064562Sgshapiro structure to the beginning of the program. This ensures that 300164562Sgshapiro the getservbyname() is done before any seteuid to a possibly 300264562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 300364562Sgshapiro on a Solaris system, this avoids syslog messages such as, 300464562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 300564562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 300664562Sgshapiro University. 300764562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 300864562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 300964562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 301064562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 301164562Sgshapiro characters (in LMTP mode), mail.local split the incoming 301264562Sgshapiro line up into 2046-character output lines (excluding the 301364562Sgshapiro newline). If an input line was 2047 characters long 301464562Sgshapiro (excluding CR-LF) and the last character was a '.', 301564562Sgshapiro mail.local saw it as the end of input, transfered it to the 301664562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 301764562Sgshapiro If the message was much longer, both sendmail and 301864562Sgshapiro mail.local would deadlock waiting for each other to read 301964562Sgshapiro what they have written. Problem noted by Peter Jeremy of 302064562Sgshapiro Alcatel Australia Limited. 302164562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 302264562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 302364562Sgshapiro Neil Rickert of Northern Illinois University. 302464562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 302564562Sgshapiro timeout to avoid starvation. 302664562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 302764562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 302864562Sgshapiro Infinite Monkeys & Co. 302964562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 303064562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 303164562Sgshapiro printed in a machine readable fashion and the stats file 303264562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 303364562Sgshapiro of Maryland. 303464562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 303564562Sgshapiro generated maps to the TrustedUser as specified in the 303664562Sgshapiro sendmail configuration file. 303764562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 303864562Sgshapiro configuration file to use for finding the TrustedUser 303964562Sgshapiro option. 304064562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 304164562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 304264562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 304364562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 304464562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 304564562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 304664562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 304764562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 304864562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 304964562Sgshapiro Corporation UK. 305064562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 305164562Sgshapiro (e.g., sendmail would not drop root privileges if the 305264562Sgshapiro option was specified on the command line). Problem noted 305364562Sgshapiro by Todd C. Miller of Courtesan Consulting. 305464562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 305564562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 305664562Sgshapiro Institute for Global Communications. 305764562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 305864562Sgshapiro alias file(s) if the -f option is not used. Patch from 305964562Sgshapiro John Beck of Sun Microsystems. 306064562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 306164562Sgshapiro configuration file to use for finding alias file(s). Patch 306264562Sgshapiro from John Beck of Sun Microsystems. 306364562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 306464562Sgshapiro lists using || and &&.

Sites 351138032Speter which need the ability to override security can use the 351238032Speter DontBlameSendmail option. See the README file for more 351338032Speter information. 351438032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 351538032Speter if maps or alias files are in world writable directories. 351638032Speter This fixes the change added to 8.8.6 to prevent links in these 351738032Speter world writable directories. 351838032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 351938032Speter it is in a world writable directory. 352038032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 352138032Speter tty it may be able to push bytes back to the senders input. 352238032Speter Unfortunately this breaks -v mode.

After this number is reached, sendmail 358238032Speter starts returning "452 Too many recipients" to all RCPT 358338032Speter commands. This can be used to limit the number of recipients 358438032Speter per envelope (in particular, to discourage use of the server 358538032Speter for spamming). Note: a better approach is to restrict 358638032Speter relaying entirely. 358738032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 358838032Speter to ldapx map and added timeout for ldap_open call to 358938032Speter avoid hanging sendmail in the event of hung LDAP servers. 359038032Speter Patch from Booker Bense of Stanford University. 359138032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 361038032Speter of Procter & Gamble. 361138032Speter The LDAP map -s flag was not properly parsed and the error message 361264562Sgshapiro given included the remainder of the arguments instead of 361338032Speter solely the argument in error. Problem noted by Aidan Nichol 361438032Speter of Procter & Gamble. 361538032Speter New DontBlameSendmail option. This option allows administrators to 361638032Speter bypass some of sendmail's file security checks at the expense 361738032Speter of system security.

In particular, if you 365338032Speter have lots of virtual interfaces, this option will speed up 365438032Speter startup. However, unless you make other arrangements, mail 365538032Speter sent to those addresses will be bounced. 365638032Speter Automatically create alias databases if they don't exist and 365738032Speter AutoRebuildAliases is set. 365838032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 365938032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 366038032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 366138032Speter When determining the client host name ($&{client_name} macro), do 366238032Speter a forward (A) DNS lookup on the result of the PTR lookup 366338032Speter and compare results. If they differ or if the PTR lookup 366438032Speter fails, &{client_name} will contain the IP address 366564562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 366638032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 366738032Speter (i.e, it is like -ax for the temporary failure case, in 366838032Speter contrast to the success case). 366938032Speter New syntax to do limited checking of header syntax. A config line 367038032Speter of the form: 367138032Speter HHeader: $>Ruleset 367238032Speter causes the indicated Ruleset to be invoked on the Header 367338032Speter when read. This ruleset works like the check_* rulesets -- 367438032Speter that is, it can reject mail on the basis of the contents. 367538032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 367638032Speter from hiding their connection information in Received: 367738032Speter headers. 367838032Speter When SingleThreadDelivery is active, deliveries to locked hosts 367938032Speter are skipped. This will cause the delivering process to 368038032Speter try the next MX host or queue the message if no other MX 368138032Speter hosts are available. Suggested by Alexander Litvin. 368238032Speter The [FILE] mailer type now delivers to the file specified in the 368338032Speter A= equate of the mailer definition instead of $u. It also 368438032Speter obeys all of the F= mailer flags such as the MIME 368538032Speter 7/8 bit conversion flags. This is useful for defining 368638032Speter a mailer which delivers to the same file regardless of the 368764562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 368838032Speter Do not assume the identity of a remote connection is root@localhost 368938032Speter if the remote connection closes the socket before the 369038032Speter remote identity can be queried. 369138032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 369238032Speter Some mailers, including procmail, require that the real 369338032Speter uid is left unchanged by sendmail. Problem noted by Per 369438032Speter Hedeland of Ericsson. 369538032Speter No longer is the src/obj*/Makefile selected from a large list -- it 369638032Speter is now generated using the information in BuildTools/OS/ -- 369738032Speter some of the details are determined dynamically via 369838032Speter BuildTools/bin/configure.sh. 369938032Speter The other programs in the sendmail distribution -- mail.local, 370038032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 370138032Speter the new Build method which creates an operating system 370238032Speter specific Makefile using the information in BuildTools. 370338032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 370438032Speter a failure on one message won't affect future messages to the 370538032Speter same host). This is necessary if the remote host sends 370638032Speter a 451 error if the domain of the sender does not resolve 370738032Speter as is common in anti-spam configurations. Problem noted 370838032Speter by Mitchell Blank Jr of Exec-PC. 370938032Speter New "discard" mailer for check_* rulesets and header checking 371038032Speter rulesets. If one of the above rulesets resolves to the 371138032Speter $#discard mailer, the commands will be accepted but the 371238032Speter message will be completely discarded after it is accepting. 371338032Speter This means that even if only one of the recipients 371438032Speter resolves to the $#discard mailer, none of the recipients 371538032Speter will receive the mail. Suggested by Brian Kantor. 371638032Speter All but the last cloned envelope of a split envelope were queued 371738032Speter instead of being delivered.

Problem noted by 375138032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 375238032Speter Include a magic number and version in the StatusFile for the 375338032Speter mailstats command. 375438032Speter Record the number of rejected and discarded messages in the 375538032Speter StatusFile for display by the mailstats command. Patch 375638032Speter from Randall Winchester of the University of Maryland. 375738032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 375838032Speter user portion as IDENT:username@site instead of 375938032Speter username@site to differentiate the two. Suggested by 376038032Speter Kari Hurtta of the Finnish Meteorological Institute. 376138032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 376238032Speter Ericsson. 376338032Speter Change persistent host status filename substitution so '/' is 376438032Speter replaced by ':' instead of '|' to avoid clashes. Also 376538032Speter avoid clashes with hostnames with leading dots. Fix from 376638032Speter Mitchell Blank Jr. of Exec-PC. 376738032Speter If the system lock table is full, only attempt to create a new 376838032Speter queue entry five times before giving up. Previously, it 376938032Speter was attempted indefinitely which could cause the partition 377038032Speter to run out of inodes. Problem noted by Suzie Weigand of 377138032Speter Stratus Computer, Inc. 377238032Speter In verbose mode, warn if the sendmail.cf version is less than the 377338032Speter currently supported version. 377438032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 377538032Speter from Randall S. Winchester of the University of Maryland. 377638032Speter Properly quote a full name passed via the -F command line option, 377738032Speter the Full-Name: header, or the NAME environment variable if 377838032Speter it contains characters which must be quoted. Problem noted 377938032Speter by Kari Hurtta of the Finnish Meteorological Institute. 378038032Speter Avoid possible race condition that unlocked a mail job before 378138032Speter releasing the transcript file on systems that use flock(2). 378238032Speter In some cases, this might result in a "Transcript Unavailable" 378338032Speter message in error bounces. 378438032Speter Accept SMTP replies which contain only a reply code and no 378538032Speter accompanying text. Problem noted by Fernando Fraticelli of 378638032Speter Digital Equipment Corporation. 378738032Speter Portability: 378838032Speter AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura 378938032Speter of Kyoto University. 379038032Speter AIX 4.2 requires <userpw.h> before <usersec.h>.

From Guillermo Freige of 381138032Speter Gobernacion de la Pcia de Buenos Aires and Paul 381238032Speter Fischer of BTG, Inc. 381338032Speter SunOS 4.X does not include memmove(). Patch from 381438032Speter Per Hedeland of Ericsson. 381538032Speter SunOS 5.7 includes getloadavg() function for determining 381638032Speter load average. Patch from John Beck of Sun 381738032Speter Microsystems. 381838032Speter CONFIG: Increment version number of config file. 381938032Speter CONFIG: add DATABASE_MAP_TYPE to set the default type of database 382038032Speter map for the various maps. The default is hash. Patch from 382138032Speter Robert Harker of Harker Systems. 382238032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 382338032Speter directory for certain programs. 382438032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 382538032Speter local mail delivery. By the default, /usr/libexec/mail.local 382638032Speter is used. This is expected to be the mail.local shipped 382738032Speter with 8.9 which is LMTP capable. The path is based on the 382838032Speter new confEBINDIR m4 variable. 382938032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 383038032Speter FEATURE(smrsh). Note that this changes the default from 383138032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 383238032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 383338032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 383438032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 383538032Speter the user to setup different .forward files for 383638032Speter user+detail addressing. 383738032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 383838032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 383938032Speter DontProbeInterfaces, and DontBlameSendmail options. 384038032Speter CONFIG: by default do not allow relaying (that is, accepting mail 384138032Speter from outside your domain and sending it to another host 384238032Speter outside your domain). 384338032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 384438032Speter any site to any site. 384538032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 384638032Speter domain as defined by the 'm' class ($=m) to relay. 384738032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 384838032Speter the MX records of the host portion of an incoming recipient. 384938032Speter CONFIG: new FEATURE(access_db) which turns on the access database 385077349Sgshapiro feature. This database gives you the ability to allow 385138032Speter or refuse to accept mail from specified domains for 385238032Speter administrative reasons. By default, names that are listed 385338032Speter as "OK" in the access db are domain names, not host names. 385438032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 385538032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 385638032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 385738032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 385838032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 385938032Speter of FEATURE(access_db) and class 'R' to lookup individual 386038032Speter host names only. 386138032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 386238032Speter using % addressing is used, e.g. user%site@othersite, 386338032Speter and othersite is in class 'R', the check_rcpt ruleset 386438032Speter will strip @othersite and recheck user@site for relaying. 386538032Speter This feature changes that behavior. It should not be 386638032Speter needed for most installations. 386738032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 386838032Speter domain portion of the mail sender is a local host. This 386938032Speter should only be used if absolutely necessary as it opens 387038032Speter a window for spammers. Patch from Randall S. Winchester of 387138032Speter the University of Maryland. 387238032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 387338032Speter block incoming mail destined for certain recipient 387438032Speter usernames, hostnames, or addresses. 387538032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 387638032Speter refused if the host part of the argument to MAIL FROM: cannot 387738032Speter be located in the host name service (e.g., DNS). 387838032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 387938032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 388038032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 388138032Speter MAIL FROM: senders which do not include a domain. 388238032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 388338032Speter Realtime Blackhole List. You can specify the RBL name 388438032Speter server to contact by specifying it as an optional argument. 388538032Speter The default is rbl.maps.vix.com. For details, see 388638032Speter http://maps.vix.com/rbl/. 388738032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 388838032Speter Local_check_rcpt from check_relay, check_mail, and 388938032Speter check_rcpt. Users with local rulesets should place the 389038032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 389138032Speter returns $#OK, the message is accepted. If the ruleset 389238032Speter returns a mailer, the appropriate action is taken, else 389338032Speter the return of the ruleset is ignored. 389438032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 389538032Speter default to support file, :include:, and program deliveries. 389638032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 389738032Speter pick the proper default value. See the SECURITY note 389838032Speter above for more information. 389938032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 390038032Speter no-op. Patch from Kari Hurtta of the Finnish 390138032Speter Meteorological Institute. 390238032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 390338032Speter daemon since DEC's /bin/mail will drop the envelope 390438032Speter sender if run as mailnull. See the Digital UNIX section 390538032Speter of src/README for more information. Problem noted by 390638032Speter Kari Hurtta of the Finnish Meteorological Institute. 390738032Speter CONFIG: .cf files are now stored in the same directory with the 390838032Speter .mc files instead of in the obj directory. 390964562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 391038032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 391138032Speter setting SingleLineFromHeader, AllowBogusHELO, and 391238032Speter MustQuoteChars respectively. 391338032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout. This 391438032Speter SMTP-like protocol allows detailed reporting of delivery 391538032Speter status on a per-user basis. Code donated by John Myers of 391638032Speter CMU (now of Netscape). 391738032Speter MAIL.LOCAL: HP-UX support from Randall S. Winchester of the 391864562Sgshapiro University of Maryland.

Problem noted by Greg Nichols of Wind 404638032Speter River Systems. 404738032Speter If SingleThreadDelivery was enabled and the remote server returned a 404838032Speter protocol error on the DATA command, the connection would be 404938032Speter closed but the persistent host status file would not be 405038032Speter unlocked so other sendmail processes could not deliver to 405138032Speter that host. Problem noted by Peter Wemm of DIALix. 405238032Speter If queueing up a message due to an expensive mailer, don't increment 405338032Speter the number of delivery attempts or set the last delivery 405438032Speter attempt time so the message will be delivered on the next 405538032Speter queue run regardless of MinQueueAge. Problem noted by 405638032Speter Brian J. Coan of the Institute for Global Communications. 405738032Speter Authentication warnings of "Processed from queue _directory_" and 405838032Speter "Processed by _username_ with -C _filename_" would be logged 405938032Speter with the incorrect timestamp.

Problem noted by 406338032Speter Jon Lewis of Florida Digital Turnpike. 406438032Speter If class dbm maps are rebuilt, sendmail will now detect this and 406538032Speter reopen the map. Previously, they could give stale 406638032Speter results during a single message processing (but would 406738032Speter recover when the next message was received). Fix from 406838032Speter Joe Pruett of Q7 Enterprises. 406938032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 407038032Speter requests. Problem noted by Kari E.

Problem noted by Kari E. Hurtta of the 407538032Speter Finnish Meteorological Institute. 407638032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 407738032Speter sendmail via a UNIX pipe. This will allow rulesets using 407838032Speter $&{client_name} to process without sending the string through 407938032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 408038032Speter A combination of deferred delivery mode, a double bounce situation, 408138032Speter and the inability to save a bounce message to 408238032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 408338032Speter to postmaster but not remove the offending envelope from the 408438032Speter queue causing it to create a new bounce message each time the 408538032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 408638032Speter Associates. 408738032Speter Remove newlines from hostname information returned via DNS. There are 408838032Speter no known security implications of newlines in hostnames as 408938032Speter sendmail filters newlines in all vital areas; however, this 409038032Speter could cause confusing error messages. 409138032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 409238032Speter rejected if any of the specified addresses were bad. This 409338032Speter behavior was modified to only reject the bad addresses and not 409438032Speter the entire message.

From Tetsu Ushijima of the 421538032Speter Tokyo Institute of Technology. 421638032Speter Fix race condition that could cause the body of a message to be 421738032Speter lost (so only the header was delivered).

Based on a patch from Steve Schweinhart of 422138032Speter Results Computing. 422238032Speter If a qf file was found in a mail queue directory that had a problem 422338032Speter (wrong ownership, bad format, etc.) and the file name was 422438032Speter exactly MAXQFNAME bytes long, then instead of being tried 422538032Speter once, it would be tried on every queue run. Problem noted 422638032Speter by Bryan Costales of Mercury Mail. 422738032Speter If the system supports an st_gen field in the status structure, 422838032Speter include it when reporting that a file has changed after open. 422938032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 423038032Speter This out to be checked as well as reported, since it is 423138032Speter theoretically possible for an attacker to remove a file after 423238032Speter it is opened and replace it with another file that has the 423338032Speter same i-number, but some filesystems (notably AFS) return 423438032Speter garbage in this field, and hence always look like the file 423538032Speter has changed. As a practical matter this is not a security 423638032Speter problem, since the files can be neither hard nor soft links, 423738032Speter and on no filesystem (that I am aware of) is it possible to 423838032Speter have two files on the same filesystem with the same i-number 423938032Speter simultaneously. 424038032Speter Delete the root Makefile from the distribution -- it is only for 424138032Speter use internally, and does not work at customer sites. 424238032Speter Fix botch that caused the second MAIL FROM: command in a single 424338032Speter transaction to clear the entire transaction.

This makes it possible to create a root 432938032Speter owned file in an arbitrary directory by inserting the symlink 433038032Speter into a writable directory after the initial lstat(2) check 433138032Speter determined that the file did not exist. The only verified 433238032Speter example of a system having these odd semantics for O_EXCL 433338032Speter and symbolic links was HP-UX prior to version 9.07. Most 433438032Speter systems do not have the problem, since a exclusive create 433538032Speter of a file disallows symbolic links. Systems that have been 433638032Speter verified to NOT have the problem include AIX 3.x, *BSD, 433738032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 433838032Speter and Ultrix. This is a potential exposure on systems that 433938032Speter have this bug and which do not have a MAILER-DAEMON alias 434038032Speter pointing at a legitimate account, since this will cause old 434138032Speter mail to be dropped in /var/tmp/dead.letter. 434238032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 434338032Speter if maps or alias files are in world writable directories. 434438032Speter If your system has alias maps in writable directories, it 434538032Speter is potentially possible for an attacker to replace the .db 434638032Speter (or .dir and .pag) files by symbolic links pointing at 434738032Speter another database; this can be used either to expose 434838032Speter information (e.g., by pointing an alias file at /etc/spwd.db 434938032Speter and probing for accounts), or as a denial-of-service attack 435038032Speter (by trashing the password database). The fix disallows 435138032Speter symbolic links entirely when rebuilding alias files or on 435238032Speter maps that are in writable directories, and always warns on 435338032Speter writable directories; 8.9 will probably consider writable 435438032Speter directories to be fatal errors. This does not represent an 435538032Speter exposure on systems that have alias files in unwritable 435638032Speter system directories. 435738032Speter SECURITY: disallow .forward or :include: files that are links (hard 435838032Speter or soft) if the parent directory (or any directory in the 435938032Speter path) is writable by anyone other than the owner. This is 436038032Speter similar to the previous case for user files. This change 436138032Speter should not affect most systems, but is necessary to prevent 436238032Speter an attacker who can write the directory from pointing such 436338032Speter files at other files that are readable only by the owner. 436438032Speter SECURITY: Tighten safechown rules: many systems will say that they 436538032Speter have a safe (restricted to root) chown even on files that 436638032Speter are mounted from another system that allows owners to give 436738032Speter away files. The new rules are very strict, trusting file 436838032Speter ownership only in those few cases where the system has 436938032Speter been verified to be at least as paranoid as necessary. 437038032Speter However, it is possible to relax the rules to partially 437138032Speter trust the ownership if the directory path is not world or 437238032Speter group writable. This might allow someone who has a legitimate 437338032Speter :include: file (referenced directly from /etc/aliases) to 437438032Speter become another non-root user if the :include: file is in a 437538032Speter non-writable directory on an NFS-mounted filesystem where 437638032Speter the local system says that giveaway is denied but it is 437738032Speter actually permitted. I believe this to be a very small set 437838032Speter of cases. If in doubt, do not point :include: aliases at 437938032Speter NFS-mounted filesystems. 438038032Speter SECURITY: When setting a numeric group id using the RunAsUser option 438138032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 438238032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 438338032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 438438032Speter The user id was still set properly. Problem noted by Uli 438538032Speter Pralle of the Technical University of Berlin. 438638032Speter Save the initial gid set for use when checking for if the 438738032Speter PrivacyOptions=restrictmailq option is set.

Patch 439438032Speter from Theo de Raadt. 439538032Speter The "Message is too large" error didn't successfully bounce the error 439638032Speter back to the sender.

Note that this should really 442838032Speter be fixed in the zone file for the domain. Problem noted by 442938032Speter Joe Rhett of Navigist, Inc. 443038032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 443138032Speter the message as having been tried; otherwise the next queue 443238032Speter run will not realize that this is a second attempt and will 443338032Speter retry immediately. Problem noted by Bryan Costales of 443438032Speter Mercury Mail. 443538032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 443638032Speter will be run until the later setting of the clock is reached. 443738032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 443838032Speter Morgan Stanley. 443938032Speter If the load average rises above the cutoff threshold (above which 444038032Speter sendmail will not process the queue at all) during a queue 444138032Speter run, abort the queue run immediately. Problem noted by 444238032Speter Bryan Costales of Mercury Mail. 444338032Speter The variable queue processing algorithm (based on the message size, 444438032Speter number of recipients, message precedence, and job age) was 444538032Speter non-functional -- either the entire queue was processed or 444638032Speter none of the queue was processed. The updated algorithm 444738032Speter does no queue run if a single recipient zero size job will 444838032Speter not be run. 444938032Speter If there is a fatal ("panic") message that will cause sendmail to 445038032Speter die immediately, never hold the error message for future 445138032Speter printing. 445238032Speter Force ErrorMode=print in -bt mode so that all errors are printed 445338032Speter regardless of the setting of the ErrorMode option in the 445438032Speter configuration file. Patch from Gregory Neil Shapiro. 445538032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 445638032Speter routine available in one of the libraries. Use it in conf.h. 445738032Speter The -m (match only) flag now works on host class maps. 445838032Speter If class hash or btree maps are rebuilt, sendmail will now detect 445938032Speter this and reopen the map. Previously, they could give 446038032Speter erroneous results during a single message processing 446138032Speter (but would recover when the next message was received). 446238032Speter Don't delete zero length queue files when doing queue runs until the 446338032Speter files are at least ten minutes old. This avoids a potential 446438032Speter race condition: the creator creates the qf file, getting back 446538032Speter a file descriptor. The queue runner locks it and deletes it 446638032Speter because it is zero length. The creator then writes the 446738032Speter descriptor that is now for a disconnected file, and the 446838032Speter job goes away. Based on a suggestion by Bryan Costales. 446938032Speter When determining the "validated" host name ($_ macro), do a forward 447038032Speter (A) DNS lookup on the result of the PTR lookup and compare 447138032Speter results. If they differ or if the PTR lookup fails, tag the 447238032Speter address as "may be forged". 447338032Speter Log null connections (i.e., hosts that connect but do not do any 447438032Speter substantive activity on the connection before disconnecting; 447538032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 447638032Speter Always permit "writes" to /dev/null regardless of the link count. 447738032Speter This is safe because /dev/null is special cased, and no open 447838032Speter or write is ever actually attempted. Patch from Villy Kruse 447938032Speter of TwinCom. 448038032Speter If a message cannot be sent because of a 552 (exceeded storage 448138032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 448238032Speter was given, don't return the body in the bounce, since there 448338032Speter is a very good chance that the message will double-bounce. 448438032Speter Fix possible line truncation if a quoted-printable had an =00 escape 448538032Speter in the body. Problem noted by Charles Karney of the Princeton 448638032Speter Plasma Physics Laboratory. 448738032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 448838032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 448938032Speter Institute. 449038032Speter The MaxDaemonChildren option wasn't applying to queue runs as 449138032Speter documented. Note that this increases the potential denial 449238032Speter of service problems with this option: an attacker can 449338032Speter connect many times, and thereby lock out queue runs as well 449438032Speter as incoming connections. If you use this option, you should 449538032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 449638032Speter to avoid this attack. Failure to limit noted by Matthew 449738032Speter Dillon of BEST Internet Communications. 449838032Speter Always give a message in newaliases if alias files cannot be 449938032Speter opened instead of failing silently. Suggested by Gregory 450038032Speter Neil Shapiro. This change makes the code match the O'Reilly 450138032Speter book (2nd edition). 450238032Speter Some older versions of the resolver could return with h_errno == -1 450338032Speter if no name server could be reached, causing mail to bounce 450438032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 450538032Speter John Beck of SunSoft. 450638032Speter If a :include: file is owned by a user that does not have an entry 450738032Speter in the passwd file, sendmail could dereference a null pointer. 450838032Speter Problem noted by Satish Mynam of Sun Microsystems. 450938032Speter Take precautions to make sure that the SMTP protocol cannot get out 451038032Speter of sync if (for example) an alias file cannot be opened. 451138032Speter Fix a possible race condition that can cause a SIGALRM to come in 451238032Speter immediately after a SIGHUP, causing the new sendmail to die. 451338032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 451438032Speter from Villy Kruse of TwinCom. 451538032Speter Ignore improperly formatted SMTP reply codes. Previously these were 451638032Speter partially processed, which could cause confusing error 451738032Speter returns. 451838032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 451938032Speter on some architectures. 452038032Speter Portability: 452138032Speter A/UX: from Jim Jagielski of NASA/GSFC. 452238032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 452338032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 452438032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 452538032Speter defined. Problem reported by A Sun of the University 452638032Speter of Washington. 452738032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 452838032Speter the system rather than guessing at compile time. 452938032Speter Patch contributed by John Beck of Sun Microsystems. 453038032Speter Intel Paragon: from Wendy Lin of Purdue University. 453138032Speter GNU Hurd: from Miles Bader of the GNU project. 453238032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 453338032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 453438032Speter Unfortunately releasing them opens a race condition, 453538032Speter but there appears to be no fix for this. Patch from 453638032Speter Gregory Neil Shapiro. 453738032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 453838032Speter Solaris: a bug in strcasecmp caused characters with the 453938032Speter high order bit set to apparently randomly match 454038032Speter letters -- for example, $| (0233) matches "i" and "I". 454138032Speter Problem noted by John Gregson of the University of 454238032Speter Cambridge. 454338032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 454438032Speter Kari Hurtta. 454538032Speter IRIX 6.x: Create Makefiles for systems that claim to be 454638032Speter IRIX64 but are 6.2 or higher (so use the regular 454738032Speter IRIX Makefile). 454838032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 454938032Speter Problem noted by Eric Hagberg of Morgan Stanley. 455038032Speter CONFIG: Some canonification was still done for UUCP-like addresses 455138032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 455238032Speter Brian Candler. 455338032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 455438032Speter local names as local. Problem noted by Jeff Polk of BSDI; 455538032Speter fix provided by Gregory Neil Shapiro. 455638032Speter CONFIG: The "local:user" syntax entries in mailertables and other 455738032Speter "mailer:user" syntax locations returned an incorrect value 455838032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 455938032Speter CONFIG: Retain "+detail" information when forwarding mail to a 456038032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 456138032Speter Guenther of Gustavus Adolphus College. 456238032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 456338032Speter rules are the same as for aliasing. Based on a patch from 456438032Speter Gregory Neil Shapiro. 456538032Speter CONFIG: Break up parsing rules into several pieces; this should 456638032Speter have no functional change in this release, but makes it 456738032Speter possible to have better anti-spam rulesets in the future. 456838032Speter CONFIG: Disallow double dots in host names to avoid having the 456938032Speter HostStatusDirectory store status under the wrong name. 457038032Speter In some cases this can be used as a denial-of-service attack. 457138032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 457238032Speter Gregory Neil Shapiro. 457338032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 457438032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 457538032Speter don't include From_, and convert to 8-bit). Suggestions 457638032Speter from Kimmo Suominen and Roderick Schertler. 457764562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 457838032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 457938032Speter was specified, even when it wasn't. 458038032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 458138032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 458238032Speter "slip in" a symbolic link between the lstat(2) call and the 458338032Speter exclusive open. This is only a problem on System V derived 458438032Speter systems that allow an exclusive create on files that are 458538032Speter symbolic links pointing nowhere. 458638032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 458738032Speter not reset back to root, which on some systems would cause 458838032Speter later mailboxes to fail. Also, any partial message would 458938032Speter not be truncated, which could result in repeated deliveries. 459038032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 459138032Speter developers). 459238032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 459338032Speter change to the sendmail map code was made in 8.8.3. Problem 459438032Speter noted by Gregory Neil Shapiro. 459538032Speter MAKEMAP: Give warnings on file problems such as map files that are 459690792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 459738032Speter often run as root and hence has the potential for the same 459838032Speter sorts of problems as alias rebuilds. 459938032Speter MAKEMAP: Change compilation so that it will link properly on 460038032Speter NEXTSTEP. 460138032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 460238032Speter Accept an optional list of arguments following the server 460338032Speter name for the ETRN arguments to use (instead of $=w). Other 460438032Speter miscellaneous bug fixes. From Christian von Roques via 460538032Speter John Beck of Sun Microsystems. 460638032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 460738032Speter Perl script converts GECOS information in the /etc/passwd 460838032Speter file into aliases, allowing for faster access to full name 460938032Speter lookups; it is also clever about adding aliases (to root) 461038032Speter for system accounts. 461138032Speter NEW FILES: 461238032Speter src/safefile.c 461338032Speter cf/ostype/gnuhurd.m4 461438032Speter cf/ostype/irix6.m4 461538032Speter contrib/passwd-to-alias.pl 461638032Speter src/Makefiles/Makefile.IRIX64.6.1 461738032Speter src/Makefiles/Makefile.IRIX64.6.x 461838032Speter RENAMED FILES: 461938032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 462038032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 462138032Speter 462264562Sgshapiro8.8.5/8.8.5 1997/01/21 462338032Speter SECURITY: Clear out group list during startup. Without this, sendmail 462438032Speter will continue to run with the group permissions of the caller, 462538032Speter even if RunAsUser is specified. 462638032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 462738032Speter to any known attack, but it's best to be conservative. 462838032Speter Suggested by Peter Wemm of DIALix. 462938032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 463038032Speter security implications. Patch from Alex Garthwaite of the 463138032Speter University of Pennsylvania. 463238032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 463338032Speter would truncate the address after "Full". Although the -f 463438032Speter syntax is incorrect (since it is in the envelope, it 463538032Speter shouldn't have comments and full names), the failure mode 463638032Speter was unnecessarily awful. 463738032Speter Fix a possible null pointer dereference when converting 8-bit data 463838032Speter to a 7-bit format. Problem noted by Jim Hutchins of 463938032Speter Sandia National Labs and David James of British Telecom. 464038032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 464138032Speter runs. Although this really shouldn't be used (F=9 is for 464238032Speter final delivery only, and using it on an SMTP mailer makes 464338032Speter it possible for a message to be converted from 8->7->8->7 464438032Speter bits several times), it shouldn't have failed with a syserr. 464538032Speter Problem noted by Eric Hagberg of Morgan Stanley. 464638032Speter _Really_ fix the multiple :maildrop code in the user database 464738032Speter module. Patch from Roy Mongiovi of Georgia Tech. 464838032Speter Let F lines in the configuration file actually read root-only 464938032Speter files if the configuration file is safe. Based on a 465038032Speter patch from Keith Reynolds of SCO. 465138032Speter ETRN followed by QUIT would hold the connection open until the queue 465238032Speter run completed. Problem noted by Truck Lewis of TDK 465338032Speter Semiconductor Corp. 465438032Speter It turns out that despite the documentation, the TCP wrappers library 465538032Speter does _not_ log rejected connections. Do the logging ourselves. 465638032Speter Problem noted by Fletcher Mattox of the University of Texas 465738032Speter at Austin. 465838032Speter If sendmail finds a qf file in its queue directory that is an unknown 465938032Speter version (e.g., when backing out to an old version), the 466038032Speter error is reported on every queue run. Change it to only 466138032Speter give the error once (and rename the qf => Qf). Patch from 466238032Speter William A. Gianopoulos of Raytheon Company. 466338032Speter Start a new session when doing background delivery; currently it 466438032Speter ignored signals but didn't start a new signal, that caused 466538032Speter some problems if a background process tried to send mail 466638032Speter under certain circumstances. Problem noted by Eric Hagberg 466738032Speter of Morgan Stanley; fix from Kari Hurtta. 466838032Speter Simplify test for skipping a queue run to just check if the current 466938032Speter load average is >= the queueing load average. Previously 467038032Speter the check factored in some other parameters that caused it 467138032Speter to essentially never skip the queue run. Patch from Bryan 467238032Speter Costales. 467338032Speter If the SMTP server is running in "nullserver" mode (that is, it is 467438032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 467538032Speter (25) commands; this helps prevent a bad guy from putting 467638032Speter you into a tight loop as a denial-of-service attack. Based 467738032Speter on an e-mail conversation with Brad Knowles of AOL. 467838032Speter Slow down when too many "light weight" commands have been issued; 467938032Speter this helps prevent a class of denial-of-service attacks. 468038032Speter The current values and defaults are: 468138032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 468238032Speter MAXHELOCOMMANDS 3 HELO, EHLO 468338032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 468438032Speter MAXETRNCOMMANDS 8 ETRN 468538032Speter These will probably be configurable in a future release. 468638032Speter On systems that have uid_t typedefed to be an unsigned short, programs 468738032Speter that had the F=S flag and no U= equate would be invoked with 468838032Speter the real uid set to 65535 rather than being left unchanged. 468938032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 469038032Speter by Steve Hubert of the University of Washington, Seattle. 469138032Speter Mail that was Quoted-Printable encoded and had a soft line break on 469238032Speter the last line (i.e., an incomplete continuation) had the last 469338032Speter line dropped. Since this appears to be illegal it isn't 469438032Speter clear what to do with it, but flushing the last line seems 469538032Speter to be a better "fail soft" approach. Based on a patch from 469638032Speter Eric Hagberg. 469738032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 469838032Speter bogus HELO command still causes the "Polite people say HELO 469938032Speter first" error message. Problem pointed out by Chris Thomas 470038032Speter of UCLA; patch from John Beck of SunSoft. 470138032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 470271345Sgshapiro in PrivacyOptions.

Problem noted by Ronan KERYELL 474238032Speter of Centre de Recherche en Informatique de l'�cole Nationale 474338032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 474438032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 474538032Speter such as LUSER_RELAY. This change permits the following 474638032Speter syntaxes: ``local:'' will send to the same user on the 474738032Speter local machine (e.g., in a mailertable entry for "host", 474838032Speter ``local:'' will cause an address addressed to user@host to 474938032Speter go to user on the local machone). ``local:user'' will send 475038032Speter to the named user on the local machine. ``local:user@host'' 475138032Speter is equivalent to ``local:user'' (the host is ignored). In 475238032Speter all cases, the original user@host is passed in $@ (i.e., the 475338032Speter detail information). Inspired by a report from Michael Fuhr. 475438032Speter CONFIG: Strip quotes from the first word of an "error:" host 475538032Speter indication. This lets you set (for example) the LUSER_RELAY 475638032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 475738032Speter of the \" so that the resulting string is properly quoted. 475838032Speter Problem noted by Gregory Neil Shapiro of WPI. 475938032Speter OP.ME: documentation was inconsistent about whether sendmail did a 476038032Speter NOOP or a RSET to probe the connection (it does a RSET). 476138032Speter Inconsistency noted by Deeran Peethamparam. 476238032Speter OP.ME: insert additional blank pages so it will print properly on 476338032Speter a duplex printer.

The solution is to disallow any 477038032Speter files that have hard links -- this will affect .forward, 477138032Speter :include:, and output files. Problem noted by Terry 477238032Speter Kyriacopoulos of Interlog Internet Services. As a 477338032Speter workaround, set UnsafeGroupWrites -- always a good idea. 477438032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 477538032Speter is, it is possible to do a denial-of-service attack on 477638032Speter MX hosts that rely on the use of the null MX list. There 477738032Speter is no danger if you have this option turned off (the default). 477838032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 477938032Speter unsafe. I know of no specific attack against this, although 478038032Speter a denial-of-service attack is probably possible, but in theory 478138032Speter you should not be able to safely tweak anything that affects 478238032Speter the permissions that are used when mail is delivered. 478338032Speter Purgestat could go into an infinite loop if one of the host status 478438032Speter directories somehow became empty. Problem noted by Roy 478538032Speter Mongiovi of Georgia Tech. 478638032Speter Processes got "lost" when counting children due to a race condition. 478738032Speter This caused "proc_list_probe: lost pid" messages to be logged. 478838032Speter Problem noted by several people. 478938032Speter On systems with System V SIGCLD child signal semantics (notably AIX 479038032Speter and HP-UX), mail transactions would print the message "451 479138032Speter SMTP-MAIL: lost child: No child processes". Problem noted 479238032Speter by several people. 479338032Speter Miscellaneous compiler warnings on picky compilers (or when setting 479438032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 479538032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 479638032Speter not be persistent between runs, since they are based on the 479738032Speter message rather than the host. Problem noted by Matt Dillon 479838032Speter of Best Internet Communications. 479938032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 480038032Speter of NCR (a.k.a., AT&T Global Information Solutions). 480138032Speter Avoid the possibility of having a child daemon run to completion 480238032Speter (including closing the SMTP socket) before the parent has 480338032Speter had a chance to close the socket; this can cause the parent 480438032Speter to hang for a long time waiting for the socket to drain. 480538032Speter Patch from Don Lewis of TDK Semiconductor. 480638032Speter If the fork() failed in a queue run, the queue runners would not be 480738032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 480838032Speter Some error conditions in ETRN could cause output without an SMTP 480938032Speter status code. Problem noted by Don Lewis. 481038032Speter Multiple :maildrop addresses in the user database didn't work properly. 481138032Speter Patch from Roy Mongiovi of Georgia Tech. 481238032Speter Add ".db" automatically onto any user database spec that does not 481338032Speter already have it; this is for consistency with makemap, the 481438032Speter K line, and the documentation. Inconsistency pointed out 481538032Speter by Roy Mongiovi. 481638032Speter Allow sendmail to be properly called in nohup mode. Patch from 481738032Speter Kyle Jones of UUNET. 481838032Speter Change ETRN to ignore but still update host status files; previously 481938032Speter it would ignore them and not save the updated status, which 482038032Speter caused stale information to be maintained. Based on a patch 482138032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 482238032Speter ETRN ignore the MinQueueAge option. 482338032Speter Patch long term host status to recover more gracefully from an empty 482438032Speter host status file condition. Patch from NAKAMURA Motonori 482538032Speter of Kyoto University. 482638032Speter Several patches to signal handling code to fix potential race 482738032Speter conditions from Don Lewis. 482838032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 482938032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 483038032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 483138032Speter compile flag; use NETINET instead. Solution based on a 483238032Speter patch from Bryan Costales. 483338032Speter PORTABILITY FIXES: 483438032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 483538032Speter /etc/security/passwd file when called as root. This 483638032Speter is very slow on some systems. To speed it up, use the 483738032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 483838032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 483938032Speter SCO 5.x: include -lprot in the Makefile.

Problem 487838032Speter noted by Eric Bishop of Virginia Tech. 487938032Speter When doing text-based host canonification (typically /etc/hosts 488038032Speter lookup), a null host name would match any /etc/hosts entry 488138032Speter with space at the end of the line. Problem noted by Steve 488238032Speter Hubert of the University of Washington, Seattle. 488338032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 488438032Speter Problem reported by Tom Smith of Digital Equipment Corp. 488538032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 488638032Speter size PACKETSZ (512) is not sufficient for some nameserver 488738032Speter answers containing very many resource records. The resolver 488838032Speter may also switch to TCP and retry if it detects UDP packet 488938032Speter overflow. Also, allow for the fact that the resolver 489038032Speter routines res_query and res_search return the size of the 489138032Speter *un*truncated answer in case the supplied answer buffer it 489238032Speter not big enough to accommodate the entire answer. Patch from 489338032Speter Eric Wassenaar. 489438032Speter Improvements to MaxDaemonChildren code. If you think you have too 489538032Speter many children, probe the ones you have to verify that they 489638032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 489738032Speter Also, do this probe before growing the vector of children 489838032Speter pids; this previously caused the vector to grow indefinitely 489938032Speter due to a race condition. Problem reported by Kyle Jones of 490038032Speter UUNET. 490138032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 490238032Speter O_EXLOCK to zero; this fools the map compilation code into 490338032Speter thinking that it can avoid race conditions by locking on open. 490438032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 490538032Speter Leif Erlingsson of Data Lege. 490638032Speter Always call res_init() on startup (if compiled in, of course) to 490738032Speter allow the sendmail.cf file to tweak resolver flags; without 490838032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 490938032Speter Andrew Sun of Merrill Lynch. 491038032Speter Improvements to host status printing code. Suggested by Steve Hubert 491138032Speter of the University of Washington, Seattle. 491238032Speter Change MinQueueAge option processing to do the check for the job age 491338032Speter when reading the queue file, rather than at the end; this 491438032Speter avoids parsing the addresses, which can do DNS lookups. 491538032Speter Problem noted by John Beck of InReference, Inc. 491638032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 491738032Speter properly escaped. Problem noted by Peter Nilsson of the 491838032Speter University of Linkoping. 491938032Speter In some cases, sendmail would retain root permissions during queue 492038032Speter runs even if RunAsUser was set. Problem noted by Mark 492138032Speter Thomas of Mark G.

If this option is null (as 500238032Speter opposed to undefined) it can cause "null signature" syserrs 500338032Speter on illegal host names. 500438032Speter If a Base64 encoded text/plain message has no trailing newline in 500538032Speter the encoded text, conversion back to 8 bits will drop the 500638032Speter final line. Problem noted by Pierre David. 500738032Speter If running with a RunAsUser, sendmail would give bogus "cannot 500838032Speter setuid" (or seteuid, or setreuid) messages on some systems. 500938032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 501038032Speter Always print error messages in -bv mode -- previously, -bv would 501138032Speter be absolutely silent on errors if the error mode was sent 501238032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 501338032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 501438032Speter term host status. This is necessary because it is common 501538032Speter to do this when you know a host has just come back up. 501638032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 501738032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 501838032Speter University of Leicester. 501938032Speter If a service (such as NIS) is specified as the last entry in the 502038032Speter service switch, but that service is not compiled in, sendmail 502138032Speter would return a temporary failure when an entry was not found 502238032Speter in the map.

In order to avoid 506738032Speter trashing memory, the buffer for all names has only been 506838032Speter slightly increased in size, to 12.8K from 10.2K -- this means 506938032Speter that if a single name had 100 MX records, the average size 507038032Speter of those records could not exceed 128 bytes.

Berkeley. 507438032Speter Print q_statdate and q_specificity in address structure debugging 507538032Speter printout. 507638032Speter Expand MCI structure flag bits for debugging output. 507738032Speter Support IPv6-style domain literals, which can have colons between 507838032Speter square braces. 507938032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 508038032Speter this is an attempt to track down a bug that one person seems 508138032Speter to be having (it may be a Solaris bug!). 508238032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 508338032Speter this caused the NOTIFY info to sometimes be lost. Problem 508438032Speter pointed out by Claus Assmann of the 508538032Speter Christian-Albrechts-University of Kiel. 508638032Speter The statistics gathered in the sendmail.st file were too high; in 508738032Speter some cases failures (e.g., user unknown or temporary failure) 508838032Speter would count as a delivery as far as the statistics were 508938032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 509038032Speter Systems that don't have flock() would not send split envelopes in 509138032Speter the initial run. Problem pointed out by Leonard Zubkoff of 509238032Speter Dandelion Digital. 509338032Speter Move buffer overflow checking -- these primarily involve distrusting 509438032Speter results that may come from NIS and DNS. 509538032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 509638032Speter include <paths.h> and hence had the wrong pathnames for a few 509738032Speter things like /var/tmp. Reported by Matthew Green. 509838032Speter Conditions were reversed for the Priority: header, resulting in all 509938032Speter values being interpreted as non-urgent except for non-urgent, 510038032Speter which was interpreted as normal. Patch from Bryan Costales. 510138032Speter The -o (optional) flag was being ignored on hash and btree maps 510238032Speter since 8.7.2. Fix from Bryan Costales. 510338032Speter Content-Types listed in class "q" will always be encoded as 510438032Speter Quoted-Printable (or more accurately, will never be encoded 510538032Speter as base64). The class can have primary types (e.g., "text") 510638032Speter or full types (e.g., "text/plain"). Based on a suggestion by 510738032Speter Marius Olafsson of the University of Iceland. 510838032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 510938032Speter dialogue) so it can be passed to programs in mailers. 511038032Speter Define ${bodytype} to be the body type (from the -B flag or the 511138032Speter BODY= ESMTP parameter) so it can be passed to programs in 511238032Speter mailers. 511338032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 511438032Speter flag is set in the mailer descriptor. Suggested by John 511538032Speter Myers of CMU. 511638032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 511738032Speter The command takes a host name; data for that host is 511838032Speter immediately (and asynchronously) flushed. Because this shares 511938032Speter the -qR implementation, other hosts may be attempted, but 512038032Speter there should be no security implications. Implementation 512138032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 512238032Speter Add three new command line flags to pass in DSN parameters: -V envid 512338032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 512438032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 512538032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 512638032Speter that the -N flag applies to all recipients; there is no way 512738032Speter to specify per-address notifications on the command line, 512838032Speter nor is there an equivalent for the ORCPT= per-address 512938032Speter parameter. 513038032Speter Restore LogLevel option to be safe (it can only be increased); 513138032Speter apparently I went into paranoid mode between 8.6 and 8.7 513238032Speter and made it unsafe. Pointed out by Dabe Murphy of the 513338032Speter University of Maryland. 513438032Speter New logging on log level 15: all SMTP traffic. Patches from 513538032Speter Andrew Gross of San Diego Supercomputer Center. 513638032Speter NetInfo property value searching code wasn't stopping when it found 513738032Speter a match. This was causing the wrong values to be found (and 513838032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 513938032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 514038032Speter out by Bill Wisner of Electronics for Imaging that you can't 514138032Speter use the bracket address form for the MAIL_HUB macro, since 514238032Speter that causes the brackets to remain in the envelope recipient 514338032Speter address used for delivery. The simple fix (stripping off the 514438032Speter brackets in the config file) breaks the use of IP literal 514538032Speter addresses. This flag will solve that problem. 514638032Speter Add MustQuoteChars option. This is a list of characters that must 514738032Speter be quoted if they are found in the phrase part of an address 514838032Speter (that is, the full name part). The characters @,;:\()[] are 514938032Speter always in this list and cannot be removed. The default is 515038032Speter this list plus . and ' to match RFC 822. 515138032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 515238032Speter that do not include a host name for back compatibility with 515338032Speter some stupid SMTP clients. Setting this violates RFC 1123 515438032Speter section 5.2.5. 515538032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 515638032Speter rejecting connections if it has more than this many 515738032Speter outstanding children accepting mail. Note that you may 515838032Speter see more processes than this because of outgoing mail; this 515938032Speter is for incoming connections only. 516038032Speter Add ConnectionRateThrottle option. If set to a positive value, the 516138032Speter number of incoming SMTP connections that will be permitted 516238032Speter in a single second is limited to this number. Connections are 516338032Speter not refused during this time, just deferred. The intent is to 516438032Speter flatten out demand so that load average limiting can kick in. 516538032Speter It is less radical than MaxDaemonChildren, which will stop 516638032Speter accepting connections even if all the connections are idle 516738032Speter (e.g., due to connection caching). 516838032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 516938032Speter specifies how long cached information about the state of a 517038032Speter host will be kept before they are considered stale and the 517138032Speter host is retried. If you are using persistent host status 517238032Speter (i.e., the HostStatusDirectory option is set) this will apply 517338032Speter between runs; otherwise, it applies only within a single queue 517438032Speter run and hence is useful only for hosts that have large queues 517538032Speter that take a very long time to run. 517638032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 517738032Speter into being a single line even if they had newlines in them 517838032Speter when read. This is to get around a botch in Lotus Notes. 517938032Speter Text class maps were totally broken -- if you ever retrieved the last 518038032Speter item in a table it would be truncated. Problem noted by 518138032Speter Gregory Neil Shapiro of WPI. 518238032Speter Extend the lines printed by the mailq command (== the -bp flag) when 518338032Speter -v is given to 120 characters; this allows more information 518438032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 518538032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 518638032Speter this was treated as end-of-input. Problem noted by Bryan 518738032Speter Costales. 518838032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 518938032Speter to the queue file. Fix from John Hughes of Atlantic 519038032Speter Technologies, Inc. 519138032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 519238032Speter if this happens in a queue run it can cause nasty delays. 519338032Speter Problem noted by Mark Horton of AT&T. 519438032Speter If userdb entries pointed to userdb entries, and there were multiple 519538032Speter values for a given key, the database cursor would get 519638032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 519738032Speter of Georgia Tech. Fixed by reading all the values and creating 519838032Speter a comma-separated list; thus, the -v output will be somewhat 519938032Speter different for this case. 520038032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 520138032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 520238032Speter of Stanford University. 520338032Speter When envelopes were split due to aliases with owner- aliases, and 520438032Speter there was some error on one of the lists, more than one of 520538032Speter the owners would get the message. Problem pointed out by 520638032Speter Roy Mongiovi of Georgia Tech. 520738032Speter Detect excessive recursion in macro expansions, e.g., $X defined 520838032Speter in terms of $Y which is defined in terms of $X. Problem 520938032Speter noted by Bryan Costales; patch from Eric Wassenaar. 521038032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 521138032Speter some cases get trashed causing bogus From_ lines. Fix from 521238032Speter Kyle Jones of UUNET. 521338032Speter When doing load average initialization, if the nlist call for avenrun 521438032Speter failed, the second and subsequent lookups wouldn't notice 521538032Speter that fact causing bogus load averages to be returned. Noted 521638032Speter by Casper Dik of Sun Holland. 521738032Speter Fix problem with incompatibility with some versions of inet_aton that 521838032Speter have changed the return value to unsigned, so a check for an 521938032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 522038032Speter This could cause mail to addresses such as [foo.com] to bounce 522138032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 522238032Speter Pasteur Institute. 522338032Speter DSNs were inconsistent if a failure occurred during the DATA phase 522438032Speter rather than the RCPT phase: the Action: would be correct, but 522538032Speter the detailed status information would be wrong. Problem noted 522638032Speter by Bob Snyder of General Electric Company. 522738032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 522838032Speter that this is the initial MUA->MTA submission. The flag current 522938032Speter does nothing, but in future releases (when MUAs start using 523038032Speter these flags) it will probably turn on things like DNS 523138032Speter canonification. 523238032Speter Default end-of-line string (E= specification on mailer [M] lines) 523338032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 523438032Speter mailers. 523538032Speter Change the internal definition for the *file* and *include* mailers 523638032Speter to have $u in the argument vectors so that they aren't 523738032Speter misinterpreted as SMTP mailers and thus use \r\n line 523838032Speter termination. This will affect anyone who has redefined 523938032Speter either of these in their configuration file. 524038032Speter Don't assume that IDENT servers close the connection after a query; 524138032Speter responses can be newline terminated. From Terry Kennedy of 524238032Speter St. Peter's College. 524338032Speter Avoid core dumps on erroneous configuration files that have 524438032Speter $#mailer with nothing following. From Bryan Costales. 524538032Speter Avoid null pointer dereference with high debug values in unlockqueue. 524638032Speter Fix from Randy Martin of Clemson University. 524738032Speter Fix possible buffer overrun when expanding very large macros. Fix 524838032Speter from Kyle Jones of UUNET. 524938032Speter After 25 EXPN or VRFY commands, start pausing for a second before 525038032Speter processing each one. This avoids a certain form of denial 525138032Speter of service attack. Potential attack pointed out by Bryan 525238032Speter Costales. 525338032Speter Allow new named (not numbered!) config file rules to do validity 525438032Speter checking on SMTP arguments: check_mail for MAIL commands and 525538032Speter check_rcpt for RCPT commands. These rulesets can do anything 525638032Speter they want; their result is ignored unless they resolve to the 525738032Speter $#error mailer, in which case the indicated message is printed 525838032Speter and the command is rejected. Similarly, the check_compat 525938032Speter ruleset is called before delivery with "from_addr $| to_addr" 526038032Speter (the $| is a meta-symbol used to separate the two addresses); 526138032Speter it can give a "this sender can't send to this recipient" 526238032Speter notification. Note that this patch allows $| to stand alone 526338032Speter in rulesets. 526438032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 526538032Speter that have the name, IP address, and port number (respectively) 526638032Speter of the SMTP client (that is, the entity at the other end of 526738032Speter the connection. These can be used in (e.g.) check_rcpt to 526838032Speter verify that someone isn't trying to relay mail through your 526938032Speter host inappropriately. Be sure to use the deferred evaluation 527038032Speter form, for example $&{client_name}, to avoid having these bound 527138032Speter when sendmail reads the configuration file. 527238032Speter Add new config file rule check_relay to check the incoming connection 527338032Speter information. Like check_compat, it is passed the host name 527438032Speter and host address separated by $| and can reject connections 527538032Speter on that basis. 527638032Speter Allow IDA-style recursive function calls. Code contributed by Mark 527738032Speter Lovell and Paul Vixie. 527838032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 527938032Speter a virtual UUCP address using either a domain address or the $k 528038032Speter macro. Based on code contributed by Mark Lovell and Paul 528138032Speter Vixie. 528238032Speter Add Stanford LDAP map. Requires special libraries that are not 528338032Speter included with sendmail. Contributed by Booker C. Bense 528438032Speter <bbense@networking.stanford.edu>; contact him for support. 528538032Speter See also the src/READ_ME file. 528638032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 528738032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 528838032Speter only for debugging deep bits of code where it is important to 528938032Speter distinguish between the single-character metasymbol $+ and the 529038032Speter two characters $, +. 529138032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 529238032Speter debug_dumpstate. 529338032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 529438032Speter files that are group writable are considered "unsafe" -- that 529538032Speter is, programs and files referenced from such files are not 529638032Speter valid recipients. 529738032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 529838032Speter name that was not in DNS or was a domain-literal. Problem 529938032Speter noted by Tom May. 530038032Speter Change the introduction to error messages to more clearly delineate 530138032Speter permanent from temporary failures; if both existed in a 530238032Speter single message it could be confusing. Suggested by John 530338032Speter Beck of InReference, Inc. 530438032Speter The IngoreDot (i) option didn't work for lines that were terminated 530538032Speter with CRLF. Problem noted by Ted Stockwell of Secure 530638032Speter Computing Corporation. 530738032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 530838032Speter message headers. Problem reported by Matt Dillon of Best 530938032Speter Internet Communications. 531038032Speter Check for bogus characters in the 0200-0237 range; since these are 531138032Speter used internally, very strange errors can occur if those 531238032Speter characters appear in headers. Problem noted by Anders Gertz 531338032Speter of Lysator. 531438032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 531538032Speter recipient mailer has the F=9 flag set, and only works on 531638032Speter text/plain body types. Code contributed by Marius Olafsson 531738032Speter of the University of Iceland. 531838032Speter Special case "postmaster" name so that it is always treated as lower 531938032Speter case in alias files regardless of configuration settings; 532038032Speter this prevents some potential problems where "Postmaster" or 532138032Speter "POSTMASTER" might not match "postmaster". In most cases 532238032Speter this change is a no-op. 532338032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 532438032Speter Costales. 532538032Speter The -a map flag was ignored for dequote maps. Problem noted by 532638032Speter Bryan Costales. 532738032Speter Fix core dump when a lookup of a class "prog" map returns no 532838032Speter response. Patch from Bryan Costales. 532938032Speter Log instances where sendmail is deferring or rejecting connections 533038032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 533138032Speter Include port number in process title for network daemons. Suggested 533238032Speter by Kyle Jones of UUNET. 533338032Speter Send ``double bounces'' (errors that occur when sending an error 533438032Speter message) to the address indicated in the DoubleBounceAddress 533538032Speter option (default: postmaster). Previously they were always 533638032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 533738032Speter Add new mode, -bD, that acts like -bd in all respects except that 533838032Speter it runs in foreground. This is useful for using with a 533938032Speter wrapper that "watches" system services. Suggested by Kyle 534038032Speter Jones of UUNET. 534138032Speter Fix botch in spacing around (parenthesized) comments in addresses 534238032Speter when the comment comes before the address. Patch from 534338032Speter Motonori Nakamura of Kyoto University. 534438032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 534538032Speter that are being bounced to postmaster, rather than "Returned 534638032Speter mail". This permits the person who is postmaster more 534738032Speter easily determine what messages are to their role as 534838032Speter postmaster versus bounces to mail they actually sent. Based 534938032Speter on a suggestion by Motonori Nakamura. 535038032Speter Add new value "time" for QueueSortOrder option; this causes the queue 535138032Speter to be sorted strictly by the time of submission. Note that 535243730Speter this can cause very bad behavior over slow lines (because 535338032Speter large jobs will tend to delay small jobs) and on nodes with 535438032Speter heavy traffic (because old things in the queue for hosts that 535538032Speter are down delay processing of new jobs). Also, this does not 535638032Speter guarantee that jobs will be delivered in submission order 535738032Speter unless you also set DeliveryMode=queue. In general, it should 535838032Speter probably only be used on the command line, and only in 535938032Speter conjunction with -qRhost.domain. In fact, there are very few 536038032Speter cases where it should be used at all. Based on an 536138032Speter implementation by Motonori Nakamura. 536238032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 536338032Speter the same manner as other rulesets. Previously a temporary 536438032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 536538032Speter of Stanford University. 536638032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 536738032Speter 5yz (permanent failure) code. The next MX host will still be 536838032Speter tried if the connection cannot be opened in the first place 536938032Speter or if the MAIL command returns a 4yz (temporary failure) code. 537038032Speter (It's hard to know what to do here, since neither RFC 974 nor 537138032Speter RFC 1123 specify when to proceed to the next MX host.) 537238032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 537338032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 537438032Speter This causes map lookups that get a temporary failure (e.g., 537538032Speter name server failure) to _not_ defer the delivery of the 537638032Speter message. This should only be used if your configuration file 537738032Speter is prepared to do something sensible in this case. Based on 537838032Speter an idea by Gregory Shapiro of WPI. 537938032Speter Fix problem finding network interface addresses. Patch from 538038032Speter Motonori Nakamura. 538138032Speter Don't reject qf entries that are not owned by your effective uid if 538290792Sgshapiro you are not running set-user-ID; this makes management of 538380785Sgshapiro certain kinds of firewall setups difficult. Patch 538480785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 538538032Speter Add persistent host status. This keeps the information normally 538638032Speter maintained within a single queue run in disk files that are 538738032Speter shared between sendmail instances. The HostStatusDirectory 538838032Speter is the directory in which the information is maintained. If 538938032Speter not set, persistent host status is turned off. If not a full 539038032Speter pathname, it is relative to the queue directory. A common 539138032Speter value is ".hoststat". 539238032Speter There are also two new operation modes: 539338032Speter * -bh prints the status of hosts that have had recent 539438032Speter connections. 539538032Speter * -bH purges the host statuses. No attempt is made to save 539638032Speter recent status information. 539738032Speter This feature was originally written by Paul Vixie of Vixie 539838032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 539938032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 540038032Speter with my insistence that things fit cleanly into the V8 540138032Speter framework is gratefully appreciated. 540238032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 540338032Speter operate). Avoids letting two sendmails on the local machine 540464562Sgshapiro open connections to the same remote host at the same time. 540538032Speter This reduces load on the other machine, but can cause mail to 540638032Speter be delayed (for example, if one sendmail is delivering a huge 540738032Speter message, other sendmails won't be able to send even small 540838032Speter messages). Also, it requires another file descriptor (for the 540938032Speter lock file) per connection, so you may have to reduce 541038032Speter ConnectionCacheSize to avoid running out of per-process 541138032Speter file descriptors. Based on the persistent host status code 541238032Speter contributed by Paul Vixie and Mark Lovell. 541338032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 541438032Speter SafeFileEnvironment option is set. Problem noted by Bryan 541538032Speter Costales. 541638032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 541738032Speter file. Problem noted by Bryan Costales. 541838032Speter If a job was aborted using the interrupt signal (e.g., control-C from 541938032Speter the keyboard), on some occasions an empty df file would be 542038032Speter left around; these would collect in the queue directory. 542138032Speter Problem noted by Bryan Costales. 542238032Speter Change the makesendmail script to enhance the search for Makefiles 542338032Speter based on release number. For example, on SunOS 5.5.1, it will 542438032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 542538032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 542638032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 542738032Speter Webmasters. 542838032Speter When creating maps using "newaliases", always map the keys to lower 542938032Speter case when creating the map unless the -f flag is specified on 543038032Speter the map itself. Previously this was done based on the F=u 543138032Speter flag in the local mailer, which meant you could create aliases 543238032Speter that you could never access. Problem noted by Bob Wu of DEC. 543338032Speter When a job was read from the queue, the bits causing notification on 543438032Speter failure or delay were always set. This caused those 543538032Speter notifications to be sent even if NOTIFY=NEVER had been 543638032Speter specified. Problem noted by Steve Hubert of the University 543738032Speter of Washington, Seattle. 543838032Speter Add new configurable routine validate_connection (in conf.c). This 543938032Speter lets you decide if you are willing to accept traffic from 544038032Speter this host. If it returns FALSE, all SMTP commands will return 544138032Speter "550 Access denied". -DTCPWRAPPERS will include support for 544238032Speter TCP wrappers; you will need to add -lwrap to the link line. 544338032Speter (See src/READ_ME for details.) 544438032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 544538032Speter bounces. Some people seemed to think that this could be 544638032Speter confusing (even though it is true). Suggested by Motonori 544738032Speter Nakamura. 544838032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 544938032Speter user early in processing to avoid potential security problems. 545038032Speter However, this means that all .forward and :include: files must 545138032Speter be readable by that user, and all files to be written must be 545238032Speter writable by that user and all programs will be executed by that 545338032Speter user. It is also incompatible with the SafeFileEnvironment 545438032Speter option. In other words, it may not actually add much to 545538032Speter security. However, it should be useful on firewalls and other 545638032Speter places where users don't have accounts and the aliases file is 545738032Speter well constrained. 545838032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 545938032Speter only on the first attempt to delivery to an address. It could 546038032Speter be set to be lower than Timeout.connect on the principle that 546138032Speter the mail should go through quickly to responsive hosts; less 546238032Speter responsive hosts get to wait for the next queue run. 546338032Speter Fix a problem on Solaris that occasionally causes programs 546438032Speter (such as vacation) to hang with their standard input connected 546538032Speter to a UDP port. It also created some signal handling problems. 546638032Speter The problems turned out to be an interaction between vfork(2) 546738032Speter and some of the libraries, particularly NIS/NIS+. I am 546838032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 546938032Speter Change user class map to do the same matching that actual delivery 547038032Speter will do instead of just a /etc/passwd lookup. This adds 547138032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 547238032Speter The Timeout.* options are not safe -- they can be used to create a 547338032Speter denial-of-service attack. Problem noted by Christophe 547438032Speter Wolfhugel. 547543730Speter Don't send PostmasterCopy messages in the event of a "delayed" 547638032Speter notification. Suggested by Barry Bouwsma. 547738032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 547838032Speter option is set, since this disables VERB mode. Suggested 547938032Speter by John Hawkinson of MIT. 548038032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 548138032Speter by Motonori Nakamura of Kyoto University. 548238032Speter Only queue messages on transient .forward open failures if there 548343730Speter were no successful opens. The previous behavior caused it 548438032Speter to queue even if a "fall back" .forward was found. Problem 548538032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 548638032Speter and Computer Science (DISCS), NUS, Singapore. 548738032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 548838032Speter is bouncing because of a MIME error during 8->7 bit conversion; 548938032Speter the encapsulated message will bounce again, causing a loop. 549038032Speter Problem noted by Steve Hubert of the University of Washington. 549138032Speter Create xf (transcript) files using the TempFileMode option value 549238032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 549338032Speter National University of Singapore. 549438032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 549538032Speter detect cases where DefaultUid is set to something that the 549638032Speter system can't cope with. 549738032Speter PORTABILITY FIXES: 549838032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 549938032Speter Atlas International. 550038032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 550138032Speter <bicknell@ufp.org>. 550238032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 550338032Speter work on the first recipient of a message due to a 550438032Speter bug in the getpwent family.

Based on a patch from Randall 554738032Speter Winchester of the University of Maryland. 554838032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 554938032Speter Robert La Ferla of Hot Software. 555038032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 555138032Speter (where "code" is an exit status) on domains (previously 555238032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 555338032Speter Foundation. 555438032Speter CONFIG: hooks for IPv6-style domain literals. 555538032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 555638032Speter if it is undefined the AliasFile option is never set; this 555738032Speter should be transparent for most everyone. Suggested by John 555838032Speter Myers of CMU. 555938032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 556038032Speter domain listed in $=w is masqueraded. With it, only those 556138032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 556238032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 556338032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 556438032Speter hosts under those domains as well as the domain headers 556538032Speter themselves. For example, if a configuration had 556638032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 556738032Speter foo.com would be masqueraded; with it, *.foo.com would be 556838032Speter masqueraded as well. Based on an implementation by Richard 556938032Speter (Pug) Bainter of U. Texas. 557038032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 557138032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 557238032Speter Keys are user names; values are outgoing mail addresses. Yes, 557338032Speter this does overlap with the user database, and figuring out 557438032Speter just when to use which one may be tricky. Based on code 557538032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 557638032Speter from Per Hedeland of Ericsson. 557738032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 557838032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 557938032Speter Keys are either fully qualified addresses or just the host 558038032Speter part (with the @ sign). For example, a table containing: 558138032Speter info@foo.com foo-info 558238032Speter info@bar.com bar-info 558338032Speter @baz.org jane@elsewhere.net 558438032Speter would send all mail destined for info@foo.com to foo-info 558538032Speter (which is presumably an alias), mail addressed to info@bar.com 558638032Speter to bar-info, and anything addressed to anyone at baz.org will 558738032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 558838032Speter and baz.org must all be in $=w. Based on discussions with 558938032Speter a great many people. 559038032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 559138032Speter Suggested by Richard Bainter. 559238032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 559338032Speter "fax" mailer. 559438032Speter CONFIG: allow mailertable entries to resolve to local:user; this 559538032Speter passes the original user@host in to procmail-style local 559638032Speter mailers as the "detail" information to allow them to do 559738032Speter additional clever processing. From Joe Pruett of 559838032Speter Teleport Corporation. Delivery to the original user can 559938032Speter be done by specifying "local:" (with nothing after the colon). 560038032Speter CONFIG: allow any context that takes "mailer:domain" to also take 560138032Speter "mailer:user@domain" to force mailing to the given user; 560238032Speter "local:user" can also be used to do local delivery. This 560338032Speter applies on *_RELAY and in the mailertable entries. Based 560438032Speter on a suggestion by Ribert Kiessling of Easynet. 560538032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 560638032Speter limits the possible domains; this reduces the number of DNS 560738032Speter lookups required to support this feature. For example, 560838032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 560938032Speter to domains under my.site.com. Code contributed by Anthony 561038032Speter Thyssen <anthony@cit.gu.edu.au>. 561138032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 561238032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 561338032Speter of WPI. 561438032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 561538032Speter event you have to define local mailers. Suggested by 561638032Speter Gregory Shapiro of WPI. 561738032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 561838032Speter be misinterpreted as a list:...; syntax. Based on a patch by 561938032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 562038032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 562138032Speter remotely connected. The address host!user was being 562238032Speter converted to host!user@thishost instead of host!user@uurelay. 562338032Speter Problem noted by William Gianopoulos of Raytheon Company. 562438032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 562538032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 562638032Speter "User has moved"; the former wording was confusing if the 562738032Speter new address is still on the local host. Based on a suggestion 562838032Speter by Andreas Luik. 562938032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 563038032Speter However, the class is not pre-initialized to contain root. 563138032Speter Suggested by Gregory Neil Shapiro. 563238032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 563338032Speter Wolfhugel. 563438032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 563538032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 563638032Speter well: this produces a slightly different mailbox format (no 563738032Speter Content-Length: headers), file ownerships and modes are 563838032Speter different (not owned by group mail; mode 600 instead of 660), 563938032Speter and the local mailer flags will have to be tweaked (make them 564038032Speter match bsd4.4) in order to use this mailer. Patches from Paul 564138032Speter Hammann of the Missouri Research and Education Network. 564238032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 564338032Speter was a delivery error, such as if the ownership on the file 564438032Speter was wrong or the mode changed between the initial stat and 564538032Speter the open.

They were not 573138032Speter properly repaired in 8.7.1. 573238032Speter Completely delete the Bcc: header if and only if there are other 573338032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 573438032Speter last being a historic botch, of course). If Bcc: is the 573538032Speter only recipient header in the message, its value is tossed, 573643730Speter but the header name is kept. The old behavior (always keep 573738032Speter the header name and toss the value) allowed primary recipients 573838032Speter to see that a Bcc: went to _someone_. 573938032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 574038032Speter sender to <address> using -f'' syslog messages. Suggested 574138032Speter by Kari Hurtta. 574238032Speter If a sequence or switch map lookup entry gets a tempfail but then 574338032Speter continues on to another map type, but the name is not found, 574438032Speter return a temporary failure from the sequence or switch map. 574538032Speter For example, if hosts search ``dns files'' and DNS fails 574638032Speter with a tempfail, the hosts map will go on and search files, 574738032Speter but if it fails the whole thing should be a tempfail, not 574838032Speter a permanent (host unknown) failure, even though that is the 574938032Speter failure in the hosts.files map. This error caused hard 575038032Speter bounces when it should have requeued. 575138032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 575290792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 575338032Speter working properly due to excessive paranoia.

Revert to the 8.6 behavior in order 575838032Speter to simplify queue management for clustered systems. Suggested 575938032Speter by Gregory Neil Shapiro of WPI. The same problem could break 576038032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 576138032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 576238032Speter Infobiogen. 576338032Speter Fix possible buffer overflow in munchstring(). This was not a security 576438032Speter problem because you couldn't specify any argument to this 576538032Speter without first giving up root privileges, but it is still a 576638032Speter good idea to avoid future problems.

Pointed out by Allan Johannesen of WPI. 578538032Speter Config files that had no AliasFile definition were defaulting to 578638032Speter using /etc/aliases; this caused problems with nullclient 578738032Speter configurations.

Fix from Brian Coan of the 581938032Speter Association for Progressive Communications. 582038032Speter If MinQueueAge was set and a message was considered but not run 582138032Speter during a queue run and the Timeout.queuereturn interval was 582238032Speter reached, a "timed out" error message would be returned that 582338032Speter didn't include the failed address (and claimed to be a warning 582438032Speter even though it was fatal). The fix is to not return such 582538032Speter messages until they are actually tried, i.e., in the next 582638032Speter MinQueueAge interval.

From Tom Moore of AT&T GIS. 588338032Speter Shorten parameters passed to syslog() in some contexts to avoid a 588438032Speter bug in many vendors' implementations of that routine. Although 588538032Speter this isn't really a bug in sendmail per se, and my solution 588638032Speter has to assume that syslog() has at least a 1K buffer size 588738032Speter internally (I know some vendors have shortened this 588838032Speter dramatically -- they're on their own), sendmail is a popular 588938032Speter target. Also, limit the size of %s arguments in sprintf. 589038032Speter These both have possible security implications. Solutions 589138032Speter suggested by Casper Dik of Sun's Network Security Group 589238032Speter (Holland), Mark Seiden, and others. 589338032Speter Fix a problem that might cause a non-standard -B (body type) 589438032Speter parameter to be passed to the next server with undefined 589538032Speter results.

Robert 590338032Speter Elz. 590438032Speter Avoid some possible null pointer dereferences. Fixes from Randy 590538032Speter Martin <WOLF@CLEMSON.EDU> 590638032Speter When sendmail starts up on systems that have no fully qualified 590738032Speter domain name (FQDN) anywhere in the first matching host map 590838032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 590938032Speter sendmail would sleep to try to find a FQDN, which it really 591038032Speter really needs. This has been changed to fall through to the 591138032Speter next map type if it can't find a FQDN -- i.e., if the hosts 591238032Speter file doesn't have a FQDN, it will try dns even though the 591338032Speter short name was found in /etc/hosts. This is probably a crock, 591438032Speter but many people have hosts files without FQDNs. Remember: 591538032Speter domain names are your friends. 591638032Speter Log a high-priority message if you can't find your FQDN during startup. 591738032Speter Suggested by Simon Barnes of Schlumberger Limited. 591838032Speter When using Hesiod, initialize it early to improve error reporting. 591938032Speter Patch from Don Lewis of Silicon Systems, Inc. 592038032Speter Apparently at least some versions of Linux have a 90 !minute!

Problem noted by Thomas Dwyer III 604838032Speter of Michigan Technological University. 604938032Speter Relax chownsafe rules slightly -- old version said that if you 605038032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 605138032Speter if fpathconf returned EINVAL or ENOSYS), assume that 605238032Speter chown is not safe. The new version falls back to whether 605338032Speter you are on a BSD system or not. This is important for 605438032Speter SunOS, which apparently always returns one of those 605538032Speter error codes. This impacts whether you can mail to files 605638032Speter or not. 605738032Speter Syntax errors such as unbalanced parentheses in the configuration 605838032Speter file could be omitted if you had "Oem" prior to the 605938032Speter syntax error in the config file. Change to always print 606038032Speter the error message. It was especially weird because it 606138032Speter would cause a "warning" message to be sent to the Postmaster 606238032Speter for every message sent (but with no transcript). Problem 606338032Speter noted by Gregory Paris of Motorola. 606438032Speter Rewrite collect and putbody to handle full 8-bit data, including 606538032Speter zero bytes. These changes are internally extensive, but 606638032Speter should have minimal impact on external function. 606738032Speter Allow full words for option names -- if the option letter is 606838032Speter (apparently) a space, then take the word following -- e.g., 606938032Speter O MatchGECOS=TRUE 607038032Speter The full list of old and new names is as follows: 607138032Speter 7 SevenBitInput 607238032Speter 8 EightBitMode 607338032Speter A AliasFile 607438032Speter a AliasWait 607538032Speter B BlankSub 607638032Speter b MinFreeBlocks/MaxMessageSize 607738032Speter C CheckpointInterval 607838032Speter c HoldExpensive 607938032Speter D AutoRebuildAliases 608038032Speter d DeliveryMode 608138032Speter E ErrorHeader 608238032Speter e ErrorMode 608338032Speter f SaveFromLine 608438032Speter F TempFileMode 608538032Speter G MatchGECOS 608638032Speter H HelpFile 608738032Speter h MaxHopCount 608838032Speter i IgnoreDots 608938032Speter I ResolverOptions 609038032Speter J ForwardPath 609138032Speter j SendMimeErrors 609238032Speter k ConnectionCacheSize 609338032Speter K ConnectionCacheTimeout 609438032Speter L LogLevel 609538032Speter l UseErrorsTo 609638032Speter m MeToo 609738032Speter n CheckAliases 609838032Speter O DaemonPortOptions 609938032Speter o OldStyleHeaders 610038032Speter P PostmasterCopy 610138032Speter p PrivacyOptions 610238032Speter Q QueueDirectory 610338032Speter q QueueFactor 610438032Speter R DontPruneRoutes 610538032Speter r, T Timeout 610638032Speter S StatusFile 610738032Speter s SuperSafe 610838032Speter t TimeZoneSpec 610938032Speter u DefaultUser 611038032Speter U UserDatabaseSpec 611143730Speter V FallbackMXHost 611238032Speter v Verbose 611338032Speter w TryNullMXList 611438032Speter x QueueLA 611538032Speter X RefuseLA 611638032Speter Y ForkEachJob 611738032Speter y RecipientFactor 611838032Speter z ClassFactor 611938032Speter Z RetryFactor 612038032Speter The old macros that passed information into sendmail have 612138032Speter been changed to options; those correspondences are: 612238032Speter $e SmtpGreetingMessage 612338032Speter $l UnixFromLine 612438032Speter $o OperatorChars 612538032Speter $q (deleted -- not necessary) 612638032Speter To avoid possible problems with an older sendmail, 612738032Speter configuration level 6 is accepted by this version of 612838032Speter sendmail; any config file using the new names should 612938032Speter specify "V6" in the configuration. 613038032Speter Change address parsing to properly note that a phrase before a 613138032Speter colon and a trailing semicolon are essentially the same 613238032Speter as text outside of angle brackets (i.e., sendmail should 613338032Speter treat them as comments). This is to handle the 613438032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 613538032Speter assume that ``group name:'' is a comment on the first 613638032Speter address and the ``;'' is a comment on the last address). 613738032Speter This requires config file support to get right. It does 613838032Speter understand that :: is NOT this syntax, and can be turned 613938032Speter off completely by setting the ColonOkInAddresses option. 614038032Speter Level 6 config files added with new mailer flags: 614138032Speter A Addresses are aliasable. 614238032Speter i Do udb rewriting on envelope as well as header 614338032Speter sender lines. Applies to the from address mailer 614438032Speter flags rather than the recipient mailer flags. 614538032Speter j Do udb rewriting on header recipient addresses. 614638032Speter Applies to the sender mailer flags rather than the 614738032Speter recipient mailer flags. 614838032Speter k Disable check for loops when doing HELO command. 614938032Speter o Always run as the mail recipient, even on local 615038032Speter delivery. 615138032Speter w Check for an /etc/passwd entry for this user. 615238032Speter 5 Pass addresses through ruleset 5. 615338032Speter : Check for :include: on this address. 615438032Speter | Check for |program on this address. 615538032Speter / Check for /file on this address. 615638032Speter @ Look up sender header addresses in the user 615738032Speter database. Applies to the mailer flags for the 615838032Speter mailer corresponding to the envelope sender 615938032Speter address, rather than to recipient mailer flags. 616038032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 616138032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 616238032Speter mailers, and the ColonOkInAddresses option. 616338032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 616438032Speter John Beck of Hewlett-Packard, who generously contributed 616538032Speter their implementation to me, which I then didn't use (see 616638032Speter mime.c for an explanation of why). This adds the 616738032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 616838032Speter to control handling of 8-bit data. These have to cope with 616938032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 617038032Speter 8-bit data that is entered without declaring it as 8-bit 617138032Speter MIME -- technically this is illegal according to the 617238032Speter specs) and labelled 8-bit data (that is, it was declared 617338032Speter as 8BITMIME in the ESMTP session or by using the 617438032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 617538032Speter set then 8-bit data is sent to non-8BITMIME machines 617638032Speter instead of converting to 7 bit (essentially using 617738032Speter just-send-8 semantics). The values for EightBitMode are: 617838032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 617938032Speter any necessary conversion of 8BITMIME to 7BIT 618038032Speter (essentially, the full MIME option). 618138032Speter p pass unlabelled 8-bit input, but convert labelled 618238032Speter 8BITMIME input to 7BIT as required (default). 618338032Speter s strict adherence: reject unlabelled 8-bit input, 618438032Speter convert 8BITMIME to 7BIT as required. The F=8 618538032Speter flag is ignored. 618638032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 618738032Speter the setting of F=8. 618838032Speter Add new internal class 'n', which is the set of MIME Content-Types 618938032Speter which can not be 8 to 7 bit encoded because of other 619038032Speter considerations. Types "multipart/*" and "message/*" are 619138032Speter never directly encoded (although their components can be). 619238032Speter Add new internal class 's', which is the set of subtypes of the 619338032Speter MIME message/* content type that can be treated as though 619438032Speter they are an RFC822 message. It is predefined to have 619538032Speter "rfc822". Suggested By Kari Hurtta. 619638032Speter Add new internal class 'e'. This is the set of MIME 619738032Speter Content-Transfer-Encodings that can be converted to 619838032Speter a seven bit format (Quoted-Printable or Base64). It is 619938032Speter preinitialized to contain "7bit", "8bit", and "binary". 620038032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 620138032Speter short name) to set the default character set to use in the 620238032Speter Content-Type: header when doing encoding of an 8-bit message 620338032Speter which isn't marked as MIME into MIME format. If the C= 620438032Speter parameter is set on the Envelope From address, use that as 620538032Speter the default encoding; else use the DefaultCharSet option. 620638032Speter If neither is set, it defaults to "unknown-8bit" as 620738032Speter suggested by RFC 1428 section 3. 620838032Speter Allow ``U=user:group'' field in mailer definition to set a default 620938032Speter user and group that a mailer will be executed as. This 621038032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 621138032Speter also set, it is the uid/gid that will always be used (that 621238032Speter is, the controlling address is ignored). The values may be 621338032Speter numeric or symbolic; if only a symbolic user is given (no 621438032Speter group) that user's default group in the passwd file is used 621538032Speter as the group. Based on code donated by Chip Rosenthal of 621638032Speter Unicom. 621738032Speter Allow `u' option to also accept user:group as a value, in the same 621838032Speter fashion as the U= mailer option. 621938032Speter Add the symbolic time zone name in the Arpanet format dates (as 622038032Speter a comment). This adds a new compile-time configuration 622138032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 622238032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 622338032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 622438032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 622538032Speter timezone()), or TZ_NONE (don't include the comment). Code 622638032Speter from Chip Rosenthal. 622738032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 622838032Speter For example, 622938032Speter O Timeout.helo = 2m 623038032Speter There are also two new suboptions "queuereturn" and 623138032Speter "queuewarn"; these subsume the old T option. Thus, to 623238032Speter set them both the preferred new syntax is 623338032Speter O Timeout.queuereturn = 5d 623438032Speter O Timeout.queuewarn = 4h 623538032Speter Sort queue by host name instead of by message priority if the 623638032Speter QueueSortOrder option (no short name) is set is set to 623738032Speter ``host''. This makes better use of the connection cache, 623838032Speter but may delay more ``interactive'' messages behind large 623938032Speter backlogs under some circumstances. This is probably a 624038032Speter good option if you have high speed links or don't do lots 624138032Speter of ``batch'' messages, but less good if you are using 624238032Speter something like PPP on a 14.4 modem. Based on code 624338032Speter contributed by Roy Mongiovi of Georgia Tech (my main 624438032Speter contribution was to make it configurable). 624538032Speter Save i-number of df file in qf file to simplify rebuilding of queue 624638032Speter after disastrous disk crash. Suggested by Kyle Jones of 624738032Speter UUNET; closely based on code from KJS DECWRL code written 624838032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 624938032Speter are NOT back compatible with 8.6 -- that is, you can convert 625038032Speter from 8.6 to 8.7, but not the other direction. 625138032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 625238032Speter route-addrs in envelopes; this is because in some cases 625338032Speter they can be sent to the shell, which interprets them as 625438032Speter I/O redirection. 625538032Speter Don't include error file (option E) with return-receipts; this 625638032Speter can be confusing. 625738032Speter Don't send "Warning: cannot send" messages to owner-* or 625838032Speter *-request addresses. Suggested by Christophe Wolfhugel 625938032Speter of the Institut Pasteur, Paris. 626038032Speter Allow -O command line flag to set long form options. 626138032Speter Add "MinQueueAge" option to set the minimum time between attempts 626238032Speter to run the queue. For example, if the queue interval 626338032Speter (-q value) is five minutes, but the minimum queue age 626438032Speter is fifteen minutes, jobs won't be tried more often than 626538032Speter once every fifteen minutes. This can be used to give 626638032Speter you more responsiveness if your delivery mode is set to 626738032Speter queue-only. 626838032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 626938032Speter :include: and .forward files. 627038032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 627138032Speter key field name, the value field name, and the field 627238032Speter delimiter. The field delimiter can be a single character 627338032Speter or the sequence "\t" or "\n" for tab or newline. 627438032Speter These are for use by NIS+ and similar access methods. 627538032Speter Change maps to always strip quotes before lookups; the -q flag 627643730Speter turns off this behavior. Suggested by Motonori Nakamura. 627738032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 627838032Speter key and value field names respectively. Code donated by 627938032Speter Sun Microsystems. 628038032Speter Add "hesiod" map class. The "file name" is used as the 628138032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 628238032Speter first value found for the match. Code donated by Scott 628338032Speter Hutton of Indiana University. 628438032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 628538032Speter specify the name of the property that is searched as the 628638032Speter key and a -v flag to specify the name of the property that 628738032Speter is returned as the value (defaults to "members"). The 628838032Speter default map is "/aliases". Some code based on code 628938032Speter contributed by Robert La Ferla of Hot Software. 629038032Speter Add "text" map class. This does slow, linear searches through 629138032Speter text files. The -z flag specifies a column delimiter 629238032Speter (defaults to any sequence of white space), the -k flag 629338032Speter sets the key column number, and the -v flag sets the 629438032Speter value column number. Lines beginning with `#' are treated 629538032Speter as comments. 629638032Speter Add "program" map class to execute arbitrary programs. The search 629738032Speter key is presented as the last argument; the output is one 629838032Speter line read from the programs standard output. Exit statuses 629938032Speter are from sysexits.h. 630038032Speter Add "sequence" map class -- searches maps in sequence until it 630138032Speter finds a match. For example, the declarations: 630238032Speter Kmap1 ... 630338032Speter Kmap2 ... 630438032Speter Kmapseq sequence map1 map2 630538032Speter defines a map "mapseq" that first searches map1; if the 630638032Speter value is found it is returned immediately, otherwise 630738032Speter map2 is searched and the value returned. 630838032Speter Add "switch" map class. This is much like "sequence" except that 630938032Speter the ordering is fetched from an external file, usually 631038032Speter the system service switch. The parameter is the name of 631138032Speter the service to switch on, and the maps that it will use 631238032Speter are the name of the switch map followed by ".service_type". 631338032Speter For example, if the declaration of the map is 631438032Speter Ksample switch hosts 631538032Speter and the system service switch specifies that hosts are 631638032Speter looked up using dns and nis in that order, then this is 631738032Speter equivalent to 631838032Speter Ksample sequence sample.dns sample.nis 631938032Speter The subordinate maps (sample.*) must already be defined. 632038032Speter Add "user" map class -- looks up users using getpwnam. Takes a 632138032Speter "-v field" flag on the definition that tells what passwd 632238032Speter entry to return -- legal values are name, passwd, uid, gid, 632338032Speter gecos, dir, and shell. Generally expected to be used with 632438032Speter the -m (matchonly) flag. 632538032Speter Add "bestmx" map class -- returns the best MX value for the host 632638032Speter listed as the value. If there are several "best" MX records 632738032Speter for this host, one will be chosen at random. 632838032Speter Add "userdb" map class -- looks up entries in the user database. 632938032Speter The "file name" is actually the tag that will be used, 633038032Speter typically "mailname". If there are multiple entries 633138032Speter matching the name, the one chosen is undefined. 633238032Speter Add multiple queue timeouts (both return and warning). These are 633338032Speter set by the Precedence: or Priority: header fields to one of 633438032Speter three values. If a Priority: is set and has value "normal", 633564562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 633638032Speter used. If no priority is set, the Precedence: is consulted; 633738032Speter if negative, non-urgent timeouts are used; if greater than 633838032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 633938032Speter are used. The timeouts are set by setting the six timeouts 634038032Speter queue{warn,return}.{urgent,normal,non-urgent}. 634138032Speter Fix problem when a mail address is resolved to a $#error mailer 634238032Speter with a temporary failure indication; it works in SMTP, 634338032Speter but when delivering locally the mail is silently discarded. 634438032Speter This patch, from Kyle Jones of UUNET, bounces it instead 634538032Speter of queueing it (queueing is very hard). 634638032Speter When using /etc/hosts or NIS-style lookups, don't assume that 634738032Speter the first name in the list is the best one -- instead, 634838032Speter search for the first one with a dot. For example, if 634938032Speter an /etc/hosts entry reads 635038032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 635138032Speter this change will use the second name as the canonical 635238032Speter machine name instead of the initial, unqualified name. 635338032Speter Change dequote map to replace spaces in quoted text with a value 635438032Speter indicated by the -s flag on the dequote map definition. 635538032Speter For example, ``Mdequote dequote -s_'' will change 635638032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 635738032Speter quoted (because of the space character). Suggested by Dan 635838032Speter Oscarsson for use in X.400 addresses. 635938032Speter Implement long macro names as ${name}; long class names can 636038032Speter be similarly referenced as $={name} and $~{name}. 636138032Speter Definitions are (e.g.) ``D{name}value''. Names that have 636238032Speter a leading lower case letter or punctuation characters are 636338032Speter reserved for internal use by sendmail; i.e., config files 636438032Speter should use names that begin with a capital letter. Based 636538032Speter on code contributed by Dan Oscarsson. 636638032Speter Fix core dump if getgrgid returns a null group list (as opposed 636738032Speter to an empty group list, that is, a pointer to a list 636838032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 636938032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 637038032Speter failed, it called syserr which called newstr which called 637138032Speter xalloc.... The newstr is now avoided for "panic" messages. 637238032Speter Reported by Stuart Kemp of James Cook University. 637338032Speter Improve connection cache timeouts; previously, they were not even 637438032Speter checked if you were delivering to anything other than an 637538032Speter IPC-connected host, so a series of (say) local mail 637638032Speter deliveries could cause cached connections to be open 637738032Speter much longer than the specified timeout. 637838032Speter If an incoming message exceeds the maximum message size, stop 637938032Speter writing the incoming bytes to the queue data file, since 638038032Speter this can fill your mqueue partition -- this is a possible 638138032Speter denial-of-service attack. 638238032Speter Don't reject all numeric local user names unless HESIOD is 638338032Speter defined. It turns out that Posix allows all-numeric 638438032Speter user names. Fix from Tony Sanders of BSDI. 638538032Speter Add service switch support. If the local OS has a service 638638032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 638738032Speter on DEC systems) that will be used; otherwise, it falls back 638838032Speter to using a local mechanism based on the ServiceSwitchFile 638938032Speter option (default: /etc/service.switch). For example, if the 639038032Speter service switch lists "files" and "nis" for the aliases 639138032Speter service, that will be the default lookup order. the "files" 639238032Speter ("local" on DEC) service type expands to any alias files 639338032Speter you listed in the configuration file, even if they aren't 639438032Speter actually file lookups. 639538032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 639638032Speter variable which tells whether or not DNS should be considered 639738032Speter canonical. This is now determined based on whether or not 639838032Speter "dns" is in the service list for "hosts". 639938032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 640038032Speter Status Notifications). DSN notifications override 640138032Speter Return-Receipt-To: headers, which are bogus anyhow -- 640238032Speter support for them has been removed. 640338032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 640438032Speter definitions to define the types used in DSN returns for 640538032Speter MTA names, addresses, and diagnostics respectively. 640638032Speter Extend heuristic to force running in ESMTP mode to look for the 640738032Speter five-character string "ESMTP" anywhere in the 220 greeting 640838032Speter message (not just the second line). This is to provide 640938032Speter better compatibility with other ESMTP servers. 641038032Speter Print sequence number of job when running the queue so you can 641138032Speter easily see how much progress you have made. Suggested 641238032Speter by Peter Wemm of DIALix. 641338032Speter Map newlines to spaces in logged message-ids; some versions of 641438032Speter syslog truncate the rest of the line after newlines. 641538032Speter Suggested by Fletcher Mattox of U. Texas. 641638032Speter Move up forking for job runs so that if a message is split into 641738032Speter multiple envelopes you don't get "fork storms" -- this 641838032Speter also improves the connection cache utilization. 641938032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 642038032Speter the purposes of refusing to send error returns. Suggested 642138032Speter by Motonori Nakamura of Ritsumeikan University. 642238032Speter Relax rules on when a file can be written when referenced from 642338032Speter the aliases file: use the default uid/gid instead of the 642438032Speter real uid/gid. This allows you to create a file owned by 642538032Speter and writable only by the default uid/gid that will work 642690792Sgshapiro all the time (without having the set-user-ID bit set). Change 642738032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 642838032Speter Microsystems. 642938032Speter Add "DialDelay" option (no short name) to provide an "extra" 643038032Speter delay for dial on demand systems. If this is non-zero 643138032Speter and a connect fails, sendmail will wait this long and 643238032Speter then try again. If it takes longer than the kernel 643338032Speter timeout interval to establish the connection, this 643438032Speter option can give the network software time to establish 643538032Speter the link. The default units are seconds. 643638032Speter Move logging of sender information to be as early as possible; 643738032Speter previously, it could be delayed a while for SMTP mail 643838032Speter sent to aliases. Suggested by Brad Knowles of the 643938032Speter Defense Information Systems Agency. 644038032Speter Call res_init() before setting RES_DEBUG; this is required by 644138032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 644238032Speter the National Computer Security Center. 644338032Speter Add xdelay= field in logs -- this is a transaction delay, telling 644438032Speter you how long it took to deliver to this address on the 644538032Speter last try. It is intended to be used for sorting mailing 644638032Speter lists to favor "quick" addresses. Provided for use by 644738032Speter the mailprio scripts (see below). 644838032Speter If a map cannot be opened, and that map is non-optional, and 644938032Speter an address requires that map for resolution, queue the 645038032Speter map instead of bouncing it. This involves creating a 645138032Speter pseudo-class of maps called "bogus-map" -- if a required 645238032Speter map cannot be opened, the class is changed to bogus-map; 645338032Speter all queries against bogus-map return "tempfail". The 645438032Speter bogus-map class is not directly accessible. A sample 645538032Speter implementation was donated by Jem Taylor of Glasgow 645638032Speter University Computing Service. 645738032Speter Fix a possible core dump when mailing to a program that talks 645838032Speter SMTP on its standard input. Fix from Keith Moore of 645938032Speter the University of Kentucky. 646038032Speter Make it possible to resolve filenames to $#local $: @ /filename; 646138032Speter previously, the "@" would cause it to not be recognized 646238032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 646338032Speter Accept a -1 signal to re-exec the daemon. This only works if 646438032Speter argv[0] is a full path to sendmail. 646538032Speter Fix bug in "addr=..." field in O option on little-endian machines 646638032Speter -- the network number wasn't being converted to network 646738032Speter byte order. Patch from Kurt Lidl of Pix Technologies 646838032Speter Corporation. 646938032Speter Pre-initialize the resolver early on; this is to avoid a bug with 647038032Speter BIND 4.9.3 that can cause the _res.retry field to get 647138032Speter reset to zero, causing all name server lookups to time 647238032Speter out. Fix from Matt Day of Artisoft. 647338032Speter Restore T line (trusted users) in config file -- but instead of 647438032Speter locking out the -f flag, they just tell whether or not 647538032Speter an X-Authentication-Warning: will be added. This really 647638032Speter just creates new entries in class 't', so "Ft/file/name" 647738032Speter can be used to read trusted user names from a file. 647838032Speter Trusted users are also allowed to execute programs even 647938032Speter if they have a shell that isn't in /etc/shells. 648038032Speter Improve NEWDB alias file rebuilding so it will create them 648138032Speter properly if they do not already exist. This had been 648238032Speter a MAYBENEXTRELEASE feature in 8.6.9. 648338032Speter Check for @:@ entry in NIS maps before starting up to avoid 648438032Speter (but not prevent, sigh) race conditions. This ought to 648538032Speter be handled properly in ypserv, but isn't. Suggested by 648638032Speter Michael Beirne of Motorola. 648738032Speter Refuse connections if there isn't enough space on the filesystem 648838032Speter holding the queue. Contributed by Robert Dana of Wolf 648938032Speter Communications. 649038032Speter Skip checking for directory permissions in the path to a file 649138032Speter when checking for file permissions iff setreuid() 649238032Speter succeeded -- it is unnecessary in that case. This avoids 649338032Speter significant performance problems when looking for .forward 649438032Speter files. Based on a suggestion by Win Bent of USC. 649538032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 649638032Speter arbitrary ruleset number assigned or "Sname = integer" 649738032Speter to assign a specific ruleset number. Reference is 649838032Speter $>name_or_number. Names can be composed of alphas, digits, 649938032Speter underscore, or hyphen (first character must be non-numeric). 650038032Speter Allow -o flag on AliasFile lines to make the alias file optional. 650138032Speter From Bryan Costales of ICSI. 650238032Speter Add NoRecipientAction option to handle the case where there is 650338032Speter no legal recipient header in the message. It can take 650438032Speter on values: 650538032Speter None Leave the message as is. The 650638032Speter message will be passed on even 650738032Speter though it is in technically 650838032Speter illegal syntax. 650938032Speter Add-To Add a To: header with any 651038032Speter recipients that it can find from 651138032Speter the envelope. This risks exposing 651238032Speter Bcc: recipients. 651338032Speter Add-Apparently-To Add an Apparently-To: header. This 651438032Speter has almost no redeeming social value, 651538032Speter and is provided only for back 651638032Speter compatibility. 651738032Speter Add-To-Undisclosed Add a header reading 651838032Speter To: undisclosed-recipients:; 651938032Speter which will have the effect of 652038032Speter making the message legal without 652138032Speter exposing Bcc: recipients. 652238032Speter Add-Bcc To add an empty Bcc: header. 652338032Speter There is a chance that mailers down 652438032Speter the line will delete this header, 652538032Speter which could cause exposure of Bcc: 652638032Speter recipients. 652738032Speter The default is NoRecipientAction=None. 652838032Speter Truncate (rather than delete) Bcc: lines in the header. This 652938032Speter should prevent later sendmails (at least, those that don't 653038032Speter themselves delete Bcc:) from considering this message to 653138032Speter be non-conforming -- although it does imply that non-blind 653238032Speter recipients can see that a Bcc: was sent, albeit not to whom. 653338032Speter Add SafeFileEnvironment option. If declared, files named as delivery 653438032Speter targets must be regular files in addition to the regular 653538032Speter checks. Also, if the option is non-null then it is used as 653638032Speter the name of a directory that is used as a chroot(2) 653738032Speter environment for the delivery; the file names listed in an 653838032Speter alias or forward should include the name of this root. 653938032Speter For example, if you run with 654038032Speter O SafeFileEnvironment=/arch 654138032Speter then aliases should reference "/arch/rest/of/path". If a 654238032Speter value is given, sendmail also won't try to save to 654338032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 654438032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 654538032Speter Support -A flag for alias files; this will comma concatenate like 654638032Speter entries. For example, given the aliases: 654738032Speter list: member1 654838032Speter list: member2 654938032Speter and an alias file declared as: 655038032Speter OAhash:-A /etc/aliases 655138032Speter the final alias inserted will be "list: member1,member2"; 655238032Speter without -A you will get an error on the second and subsequent 655338032Speter alias for "list". Contributed by Bryan Costales of ICSI. 655438032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 655538032Speter Fix a problem that could cause very long addresses to core dump in 655638032Speter some special circumstances. Problem pointed out by Allan 655738032Speter Johannesen. 655838032Speter (Internal change.) Change interface to expand() (macro expansion) 655938032Speter to be simpler and more consistent. 656038032Speter Delete check for funny qf file names. This didn't really give 656138032Speter any extra security and caused some people some problems. 656238032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 656338032Speter at compile time.) Suggested by Kyle Jones of UUNET. 656438032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 656538032Speter merge with DSN code; this is simpler and more consistent. 656638032Speter This may affect some people who have written their own 656738032Speter checkcompat() routine. 656838032Speter (Internal change.) Eliminate `D' line in qf file. The df file 656938032Speter is now assumed to be the same name as the qf file (with 657038032Speter the `q' changed to a `d', of course). 657138032Speter Avoid forking for delivery if all recipient mailers are marked as 657238032Speter "expensive" -- this can be a major cost on some systems. 657338032Speter Essentially, this forces sendmail into "queue only" mode 657438032Speter if all it is going to do is queue anyway. 657538032Speter Avoid sending a null message in some rather unusual circumstances 657638032Speter (specifically, the RCPT command returns a temporary 657738032Speter failure but the connection is lost before the DATA 657838032Speter command). Fix from Scott Hammond of Secure Computing 657938032Speter Corporation. 658038032Speter Change makesendmail to use a somewhat more rational naming scheme: 658138032Speter Makefiles and obj directories are named $os.$rel.$arch, 658238032Speter where $os is the operating system (e.g., SunOS), $rel is 658338032Speter the release number (e.g., 5.3), and $arch is the machine 658438032Speter architecture (e.g., sun4). Any of these can be omitted, 658538032Speter and anything after the first dot in a release number can 658638032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 658738032Speter version used $os.$arch.$rel and was rather less general. 658838032Speter Change makesendmail to do a "make depend" in the target directory 658938032Speter when it is being created. This involves adding an empty 659038032Speter "depend:" entry in most Makefiles. 659138032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 659238032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 659338032Speter of the Finnish Meteorological Institute. 659438032Speter Fix problem that could cause multiple responses to DATA command 659538032Speter on header syntax errors (e.g., lines beginning with colons). 659638032Speter Problem noted by Jens Thomassen of the University of Oslo. 659738032Speter Don't let null bytes in headers cause truncation of the rest of 659838032Speter the header. 659938032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 660038032Speter Increase timeouts on message data puts to allow time for receivers 660138032Speter to canonify addresses in headers on the fly. This is still 660238032Speter a rather ugly heuristic. From Motonori Nakamura. 660338032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 660438032Speter records are not used when canonifying names, and when MX 660538032Speter lookups are done for addressing they must be fully 660638032Speter qualified. This is useful if you have a wildcard MX record, 660738032Speter although it may cause other problems. In general, don't use 660838032Speter wildcard MX records. Patch from Motonori Nakamura. 660938032Speter Eliminate default two-line SMTP greeting message. Instead of 661038032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 661138032Speter is added between the first and second word of the first 661238032Speter line of the greeting message (i.e., immediately after the 661338032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 661438032Speter compile flag. Old sendmails won't see the ESMTP, but that's 661538032Speter acceptable because SIZE was the only useful extension that 661638032Speter old sendmails understand. 661738032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 661838032Speter invoked state dumps. From Masaharu Onishi. 661938032Speter Allow on-line comments in .forward and :include: files; they are 662038032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 662138032Speter is a space or a tab. This is intended for native 662238032Speter representation of non-ASCII sets such as Japanese, where 662338032Speter existing encodings would be unreadable or would lose 662438032Speter data -- for example, 662538032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 662638032Speter (romanized/less information) 662738032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 662838032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 662938032Speter (with MIME encoding, not human readable) 663038032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 663138032Speter (native encoding with ISO-2022-JP) 663238032Speter The last form is human readable in the Japanese environment. 663338032Speter Based on a fix from (surprise!) Motonori Nakamura. 663438032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 663538032Speter messages to that host; these are most frequently associated 663638032Speter with addresses rather than the host, with the exception of 663738032Speter 421 (service shutting down). The effect was to cause queues 663838032Speter to sometimes take an excessive time to flush. Reported by 663938032Speter Robert Sargent of Southern Geographics Technologies and 664038032Speter Eric Prestemon of American University. 664138032Speter Add Nice=N mailer option to set the niceness at which a mailer will 664238032Speter run. This is actually a relative niceness (that is, an 664338032Speter increment on the background value). 664438032Speter Log queue runs that are skipped due to high loads. They are logged 664538032Speter at LOG_INFO priority iff the log level is > 8. Contributed 664638032Speter by Bruce Nagel of Data General. 664738032Speter Allow the error mailer to accept a DSN-style error status code 664838032Speter instead of an sysexits status code in the host part. 664938032Speter Anything with a dot will be interpreted as a DSN-style code. 665038032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 665138032Speter to encode characters that might be munged by an EBCDIC system 665238032Speter in addition to the set required by RFC 1521. The additional 665338032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 665438032Speter (Think of "IBM 360" as the mnemonic for this flag.) 665538032Speter Change check for mailing to files to look for a pathname of [FILE] 665638032Speter rather than looking for the mailer named *file*. The mapping 665738032Speter of leading slashes still goes to the *file* mailer. This 665838032Speter allows you to implement the *file* mailer as a separate 665938032Speter program, for example, to insert a Content-Length: header 666038032Speter or do special security policy. However, note that the usual 666138032Speter initial checking for the file permissions is still done, and 666238032Speter the program in question needs to be very careful about how 666338032Speter it does the file write to avoid security problems. 666438032Speter Be able to read ~root/.forward even if the path isn't accessible to 666538032Speter regular users. This is disrecommended because sendmail 666638032Speter sometimes does not run as root (e.g., when an unsafe option 666738032Speter is specified on the command line), but should otherwise be 666838032Speter safe because .forward files must be owned by the user for 666938032Speter whom mail is being forwarded, and cannot be a symbolic link. 667038032Speter Suggested by Forrest Aldrich of Wang Laboratories. 667138032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 667238032Speter file. This is used for canonifying hostnames when the 667338032Speter service type is "files". 667438032Speter Implement programs on F (read class from file) line. The syntax is 667538032Speter Fc|/path/to/program to read the output from the program 667638032Speter into class "c". 667738032Speter Probe the network interfaces to find alternate names for this 667838032Speter host. Requires the SIOCGIFCONF ioctl call. Code 667938032Speter contributed by SunSoft. 668038032Speter Add "E" configuration line to set or propagate environment 668138032Speter variables into children. "E<envar>" will propagate 668238032Speter the named variable from the environment when sendmail 668338032Speter was invoked into any children it calls; "E<envar>=<value>" 668438032Speter sets the named variable to the indicated value. Any 668538032Speter variables not explicitly named will not be in the child 668638032Speter environment. However, sendmail still forces an 668738032Speter "AGENT=sendmail" environment variable, in part to enforce 668838032Speter at least one environment variable, since many programs and 668938032Speter libraries die horribly if this is not guaranteed. 669038032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 669138032Speter alias databases -- new algorithm looks for the substring 669238032Speter "/yp/" in the file name. This is more portable and involves 669338032Speter less overhead. Suggested by Motonori Nakamura. 669438032Speter Dynamically allocate the queue work list so that you don't lose 669538032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 669638032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 669738032Speter should not need to be changed) and the MaxQueueRunSize option, 669838032Speter which is the absolute maximum number of jobs that will ever 669938032Speter be handled in a single queue run. Based on code contributed 670038032Speter by Brian Coan of the Institute for Global Communications. 670138032Speter Log message when a message is dropped because it exceeds the maximum 670238032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 670338032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 670438032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 670538032Speter of Mark G. Thomas Consulting. 670638032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 670738032Speter OS-dependent defines). The old semantic of -d0.1 to not 670838032Speter run the daemon in background has been moved to -d99.100, 670938032Speter and the old 52.5 flag (to avoid disconnect() from closing 671038032Speter all output files) has been moved to 52.100. This makes 671138032Speter things more consistent (flags below .100 don't change 671238032Speter semantics) and separates out the backgrounding so that 671338032Speter it doesn't happen automatically on other unrelated debugging 671438032Speter flags. 671538032Speter If -t is used but no addresses are found in the header, give an 671638032Speter error message rather than just doing nothing. Fix from 671738032Speter Motonori Nakamura. 671838032Speter On systems (like SunOS) where the effective gid is not necessarily 671938032Speter included in the group list returned by getgroups(), the 672038032Speter `restrictmailq' option could sometimes cause an authorized 672138032Speter user to not be able to use `mailq'. Fix from Charles Hannum 672238032Speter of MIT. 672338032Speter Allow symbolic service names for [IPC] mailers. Suggested by 672438032Speter Gerry Magennis of Logica International. 672538032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 672638032Speter when running DNS. For example, if the name FTP.Foo.ORG is 672738032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 672838032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 672938032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 673038032Speter This is technically illegal under RFC 822 and 1123, but the 673138032Speter IETF is moving toward legalizing it. Note that turning on 673238032Speter this option is not sufficient to guarantee that a downstream 673338032Speter neighbor won't rewrite the address for you. 673438032Speter Add "-m" flag to makesendmail script -- this tells you what object 673538032Speter directory and Makefile it will use, but doesn't actually do 673638032Speter the make. 673738032Speter Do some additional checking on the contents of the qf file to try 673838032Speter to detect attacks against the qf file. In particular, 673938032Speter abort on any line beginning "From ", and add an "end of 674038032Speter file" line -- any data after that line is prohibited. 674138032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 674238032Speter choices. This can be overridden in the Makefile by using 674338032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 674438032Speter (to the extent that we know it) or by defining 674538032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 674638032Speter sendmail 8 to have more consistent installation instructions. 674738032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 674838032Speter of Sun Microsystems. 674938032Speter Improved symbol table hash function from Eric Wassenaar. This one 675038032Speter is at least 50% faster. 675138032Speter Fix problem that didn't notice that timeout on file open was a 675238032Speter transient error. Fix from Larry Parmelee of Cornell 675338032Speter University. 675438032Speter Allow comments (lines beginning with a `#') in files read for 675538032Speter classes. Suggested by Motonori Nakamura. 675638032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 675738032Speter of dropping out entirely. This makes testing some of the 675838032Speter name server lookups easier to deal with when there are 675938032Speter hung servers. From Motonori Nakamura. 676038032Speter Add new ${opMode} macro that is set to the current operation mode 676138032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 676238032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 676338032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 676438032Speter Kind of like queue-only mode (Odq) except it tries to avoid 676538032Speter any external service requests; for dial-on-demand hosts that 676638032Speter want to minimize DNS lookups when mail is being queued. For 676738032Speter this to work you will also have to make sure that gethostbyname 676838032Speter of your local host name does not do a DNS lookup. 676938032Speter Improved handling of "out of space" conditions from John Myers of 677038032Speter Carnegie Mellon. 677138032Speter Improved security for mailing to files on systems that have fchmod(2) 677238032Speter support. 677338032Speter Improve "cannot send message for N days" message -- now says "could 677438032Speter not send for past N days". Suggested by Tom Moore of AT&T 677538032Speter Global Information Solutions. 677638032Speter Less misleading Subject: line on messages sent to postmaster only. 677738032Speter From Motonori Nakamura. 677838032Speter Avoid duplicate error messages on bad command line flags. From 677938032Speter Motonori Nakamura. 678038032Speter Better error message for case where ruleset 0 falls off the end 678138032Speter or otherwise does not resolve to a canonical triple. 678238032Speter Fix a problem that could cause multiple bounce messages if a bad 678338032Speter address was sent along with a good address to an SMTP 678438032Speter site where that SMTP site returned a 4yz code in response 678538032Speter to the final dot of the data. Problem reported by David 678638032Speter James of British Telecom. 678738032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 678838032Speter from Alexander Dupuy of System Management ARTS. 678938032Speter Delete duplicates in MX lists -- believe it or not, there are sites 679038032Speter that list the same host twice in an MX list. This deletion 679138032Speter only works on adjacent preferences, so an MX list that 679238032Speter had A=5, B=10, A=15 would leave both As, but one that had 679338032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 679438032Speter just in case there is something weird I haven't thought of. 679538032Speter Suggested by Barry Shein of Software Tool & Die. 679638032Speter SECURITY: .forward files cannot be symbolic links. If they are, 679738032Speter a bad guy can read your private files. 679838032Speter PORTABILITY FIXES: 679938032Speter Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>. 680038032Speter System V Release 4 from Motonori Nakamura of Ritsumeikan 680138032Speter University.

This means that the 681538032Speter sizeof operator returns only multiples of 8. 681638032Speter This requires adaptation of code that really 681738032Speter deals with 32 bit or 16 bit fields, such as IP 681838032Speter addresses or nameserver fields.'' 681938032Speter DG/UX 5.4.3 from Mark T.

This can 690438032Speter be used as an alternative to /bin/sh for the "prog" mailer, 690538032Speter giving the local administrator more control over what 690638032Speter programs can be run from sendmail. 690738032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 690838032Speter part of the release proper, and isn't fully supported; in 690938032Speter particular, it does not run on System V based systems and 691038032Speter never will. 691138032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 691238032Speter to allow rmail to compile on systems that don't have 691338032Speter function prototypes and systems that don't have snprintf. 691438032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 691538032Speter lists by transaction delay times so that addresses that 691638032Speter respond quickly get sent first. This is to prevent very 691738032Speter sluggish servers from delaying other peoples' mail. 691838032Speter Contributed by Tony Sanders of BSDI. 691938032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 692038032Speter of BSDI. This has a lot of comments to help people out. 692138032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 692238032Speter put this on the m4 command line. On GNU m4 (which 692338032Speter supports the __file__ primitive) you can run m4 in an 692438032Speter arbitrary directory -- use either: 692538032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 692638032Speter or 692738032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 692838032Speter On other versions of m4 that don't support __file__, you 692938032Speter can use: 693038032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 693138032Speter (Note the trailing slash on the _CF_DIR_ definition.) 693238032Speter Old versions of m4 will default to _CF_DIR_=.. for back 693338032Speter compatibility. 693438032Speter CONFIG: fix mail from <> so it will properly convert to 693538032Speter MAILER-DAEMON on local addresses. 693638032Speter CONFIG: fix code that was supposed to catch colons in host 693738032Speter names. Problem noted by John Gardiner Myers of CMU. 693838032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 693938032Speter From Paul Riddle of the University of Maryland, Baltimore 694038032Speter County. 694138032Speter CONFIG: Catch and reject "." as a host address. 694238032Speter CONFIG: Generalize domaintable to look up all domains, not 694338032Speter just unqualified ones. 694438032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 694538032Speter was never used and didn't work anyway. 694638032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 694738032Speter and d on all mailers in the UUCP class. 694838032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 694938032Speter look for an alias for "user+detail", then for "user+*", and 695038032Speter finally for "user". This is intended for forwarding mail 695138032Speter for system aliases such as root and postmaster to a 695238032Speter centralized hub. 695338032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 695438032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 695538032Speter The F=8 flag is also set on the "relay" mailer, since 695638032Speter this is expected to be another sendmail. 695738032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 695838032Speter the name of the UUCP_RELAY -- in some cases, this is the 695938032Speter wrong value (e.g., when we have local UUCP connections), 696038032Speter and this can create unreplyable addresses. From Chip 696138032Speter Rosenthal of Unicom. 696238032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 696364562Sgshapiro Received: header inserted into all messages. Suggested by 696438032Speter Gary Mills of the University of Manitoba. 696538032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 696643730Speter to get the old behavior. I did this upon observing 696738032Speter that almost everyone needed this feature, and that the 696838032Speter concept I was trying to make happen didn't work with 696938032Speter some user agents anyway. FEATURE(notsticky) still works, 697038032Speter but it is a no-op. 697138032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 697238032Speter names are sent, rather than immediately diagnosing them 697338032Speter as User Unknown. 697438032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 697538032Speter and RELAY_MAILER_ARGS to set the arguments for the 697638032Speter indicated mailers. All default to "IPC $h". Patch from 697738032Speter Larry Parmelee of Cornell University. 697838032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 697938032Speter on the client side" and F=P to get an appropriate 698038032Speter return-path. From Kimmo Suominen. 698138032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 698238032Speter as the local mailer. For addresses of the form "user+detail" 698338032Speter the "detail" part is passed to procmail via the -a flag. 698438032Speter Contributed by Kimmo Suominen. 698538032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 698638032Speter use from mailertables. This lets you execute arbitrary 698738032Speter procmail scripts. Contributed by Kimmo Suominen. 698838032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 698938032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 699038032Speter Paul Southworth of CICNet Systems Support. 699138032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 699238032Speter This causes the null return path to be rewritten as 699338032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 699438032Speter From Michael Hohmuth of Technische Universitat Dresden. 699538032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 699638032Speter list us as the best possible MX record to be treated as 699738032Speter though they were local (essentially, assume that they 699838032Speter are included in $=w). This can cause additional DNS 699938032Speter traffic, but is easier to administer if this fits your 700038032Speter local model. It does not work reliably if there are 700138032Speter multiple hosts that share the best MX preference. 700238032Speter Code contributed by John Oleynick of Rutgers. 700338032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 700438032Speter SHell) instead of /bin/sh as the program used for delivery 700538032Speter to programs. If an argument is included, it is used as 700638032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 700738032Speter assumed. 700838032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 700938032Speter size of messages to the local and procmail mailers 701038032Speter respectively. Contributed by Brad Knowles of the Defense 701138032Speter Information Systems Agency. 701238032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 701338032Speter (just like text outside of angle brackets) in order to 701438032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 701538032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 701638032Speter any real systems any more) and tweak the DOMAIN macro 701738032Speter so that it is less likely that users will accidentally use 701838032Speter the Berkeley defaults. Also, create some generic files 701938032Speter that really can be used in the real world. 702038032Speter CONFIG: Add new configuration macros to set character sets for 702138032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 702238032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 702338032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 702438032Speter The old name will still be accepted for a while at least. 702538032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 702638032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 702738032Speter As with all relays, it can be ``mailer:hostname''. Suggested 702838032Speter by Scott Hutton. 702938032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 703038032Speter by Barb Dijker of Labyrinth Computer Services. 703138032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 703238032Speter performance for large alias files, and this confused many 703338032Speter people. 703438032Speter CONFIG: Add confCF_VERSION to append local information to the 703538032Speter configuration version number displayed during SMTP startup. 703638032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 703738032Speter would only work when locally addressed. Fix from 703838032Speter Edvard Tuinder of Cistron Internet Services. 703938032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 704043730Speter "n" (CheckAliases) is set when rebuilding alias database. 704138032Speter Based on code contributed by Claude Marinier. 704238032Speter CONFIG: Allow mailertable to have values of the form 704338032Speter ``error:code message''. The ``code'' is a status code 704438032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 704538032Speter Contributed by David James <dwj@agw.bt.co.uk>. 704638032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 704738032Speter sender domains that will be replaced with the masquerade name. 704838032Speter These domains will not be treated as local, but if mail passes 704938032Speter through with sender addresses in those domains they will be 705038032Speter replaced by the masquerade name. These can also be specified 705138032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 705238032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 705338032Speter as well as the header. Substantial improvements to this 705438032Speter code were contributed by Per Hedeland. 705538032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 705638032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 705738032Speter by Kimmo Suominen. 705838032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 705938032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 706038032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 706138032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 706238032Speter UUCP addressing.

717364562Sgshapiro8.6.12/8.6.12 1995/03/28 717438032Speter Fix to IDENT code (it was getting the size of the reply buffer 717538032Speter too small, so nothing was ever accepted). Fix from several 717638032Speter people, including Allan Johannesen, Shane Castle of the 717738032Speter Boulder County Information Services, and Jeff Smith of 717838032Speter Warwick University (all arrived within a few hours of 717938032Speter each other!). 718038032Speter Fix a problem that could cause large jobs to run out of 718138032Speter file descriptors on systems that use vfork() rather 718238032Speter than fork(). 718338032Speter 718464562Sgshapiro8.6.11/8.6.11 1995/03/08 718538032Speter The ``possible attack'' message would be logged more often 718638032Speter than necessary if you are using Pine as a user agent. 718738032Speter The wrong host would be reported in the ``possible attack'' 718838032Speter message when attempted from IDENT. 718938032Speter In some cases the syslog buffer could be overflowed when 719038032Speter reporting the ``possible attack'' message. This can 719138032Speter cause denial of service attacks. Truncate the message 719238032Speter to 80 characters to prevent this problem. 719338032Speter When reading the IDENT response a loop is needed around the 719438032Speter read from the network to ensure that you don't get 719538032Speter partial lines. 719638032Speter Password entries without any shell listed (that is, a null 719738032Speter shell) wouldn't match as "ok". Problem noted by 719838032Speter Rob McMahon. 719938032Speter When running BIND 4.9.x a problem could occur because the 720038032Speter _res.options field is initialized differently than it 720138032Speter was historically -- this requires that sendmail call 720238032Speter res_init before it tweaks any bits. 720338032Speter Fix an incompatibility in openxscript() between the file open mode 720438032Speter and the stdio mode passed to fdopen. This caused UnixWare 720538032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 720638032Speter Novell Labs Europe. 720738032Speter Fix problem with static linking of local getopt routine when 720838032Speter using GNU's ld command. Fix from John Kennedy of 720938032Speter Cal State Chico. 721038032Speter It was possible to turn off privacy flags. Problem noted by 721138032Speter *Hobbit*. 721238032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 721338032Speter and Liudvikas Bukys. 721438032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 721538032Speter from Spider Boardman. 721638032Speter CONFIG: No changes (version number only, to keep it in sync 721738032Speter with the binaries). 721838032Speter 721964562Sgshapiro8.6.10/8.6.10 1995/02/10 722038032Speter SECURITY: Diagnose bogus values to some command line flags that 722138032Speter could allow trash to get into headers and qf files. 722238032Speter Validate the name of the user returned by the IDENT protocol. 722338032Speter Some systems that really dislike IDENT send intentionally 722438032Speter bogus information. Problem pointed out by Michael Bushnell 722538032Speter of the Free Software Foundation. Has some security 722638032Speter implications. 722738032Speter Fix a problem causing error messages about DNS problems when 722838032Speter the host name contained a percent sign to act oddly 722938032Speter because it was passed as a printf-style format string. 723038032Speter In some cases this could cause core dumps. 723138032Speter Avoid possible buffer overrun in returntosender() if error 723238032Speter message is quite long. From Fletcher Mattox of the 723338032Speter University of Texas. 723438032Speter Fix a problem that would silently drop "too many hops" error 723538032Speter messages if and only if you were sending to an alias. 723638032Speter From Jon Giltner of the University of Colorado and 723738032Speter Dan Harton of Oak Ridge National Laboratory. 723838032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 723938032Speter set and e->e_message was null. Fix from Bruce Nagel of 724038032Speter Data General. 724138032Speter Fix problem that can still cause df files to be left around 724238032Speter after "hop count exceeded" messages. Fix from Andrew 724338032Speter Chang and Shau-Ping Lo of SunSoft. 724438032Speter Fix a problem that can cause buffer overflows on very long 724538032Speter user names (as might occur if you piped to a program 724638032Speter with a lot of arguments). 724738032Speter Avoid returning an error and re-queueing if the host signature 724838032Speter is null; this can occur on addresses like ``user@.''. 724938032Speter Problem noted by Wesley Craig and the University of 725038032Speter Michigan. 725138032Speter Avoid possible calls to malloc(0) if MCI caching is turned 725238032Speter off. Bug fix from Pierre David of the Laboratoire 725338032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 725438032Speter Universite de Versailles - St Quentin, and Jacky 725538032Speter Thibault. 725638032Speter Make a local copy of the line being sent via senttolist() -- in 725738032Speter some cases, buffers could get trashed by map lookups 725838032Speter causing it to do unexpected things. This also simplifies 725938032Speter some of the map code. 726038032Speter CONFIG: No changes (version number only, to keep it in sync 726138032Speter with the binaries). 726238032Speter 726364562Sgshapiro8.6.9/8.6.9 1994/04/19 726438032Speter Do all mail delivery completely disconnected from any terminal. 726538032Speter This provides consistency with daemon delivery and 726638032Speter may have some security implications. 726738032Speter Make sure that malloc doesn't get called with zero size, 726838032Speter since that fails on some systems. Reported by Ed 726938032Speter Hill of the University of Iowa. 727038032Speter Fix multi-line values for $e (SMTP greeting message). Reported 727138032Speter by Mike O'Connor of Ford Motor Company. 727238032Speter Avoid syserr if no NIS domain name is defined, but the map it 727338032Speter is trying to open is optional. From Win Bent of USC. 727438032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 727538032Speter Hesiod support for UDB from Todd Miller of the University of 727638032Speter Colorado. Use "hesiod" as the service name in the U 727738032Speter option. 727838032Speter Fix a problem that failed to set the "authentic" host name (that 727938032Speter is, the one derived from the socket info) if you called 728038032Speter sendmail -bs from inetd. Based on code contributed by 728138032Speter Todd Miller (this problem was also reported by Guy Helmer 728238032Speter of Dakota State University). This also fixes a related 728338032Speter problem reported by Liudvikas Bukys of the University of 728438032Speter Rochester. 728538032Speter Parameterize "nroff -h" in all the Makefiles so people with 728638032Speter variant versions can use them easily. Suggested by 728738032Speter Peter Collinson of Hillside Systems. 728838032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 728938032Speter spaces between parameters instead of one. Reported by 729038032Speter Valdis Kletnieks of Virginia Tech. 729138032Speter Reduce the number of system calls during message collection by 729238032Speter using global timeouts around the collect() loop. This 729338032Speter code was contributed by Eric Wassenaar. 729438032Speter If the initial hostname name gathering results in a name 729538032Speter without a dot (usually caused by NIS misconfiguration) 729638032Speter and BIND is compiled in, directly access DNS to get 729738032Speter the canonical name. This should make life easier for 729838032Speter Solaris systems. If it still can't be resolved, and 729938032Speter if the name server is listed as "required", try again 730038032Speter in 30 seconds. If that also fails, exit immediately to 730138032Speter avoid bogus "config error: mail loops back to myself" 730238032Speter messages. 730338032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 730438032Speter message to explain how much space was available and 730538032Speter sound a bit less threatening. Suggested by Stan Janet 730638032Speter of the National Institute of Standards and Technology. 730738032Speter If mail is delivered to an alias that has an owner, deliver any 730838032Speter requested return-receipt immediately, and strip the 730938032Speter Return-Receipt-To: header from the subsequent message. 731038032Speter This prevents a certain class of denial of service 731138032Speter attack, arguably gives more reasonable semantics, and 731238032Speter moves things more towards what will probably become a 731338032Speter network standard. Suggested by Christopher Davis of 731438032Speter Kapor Enterprises. 731538032Speter Add a "noreceipts" privacy flag to turn off all return receipts 731638032Speter without recompiling. 731738032Speter Avoid printing ESMTP parameters as part of the error message 731838032Speter if there are errors during parsing. This change is 731938032Speter purely cosmetic. 732038032Speter Avoid sending out error messages during the collect phase of 732138032Speter SMTP; there is an MVS mailer from UCLA that gets 732238032Speter confused by this. Of course, I think it's their bug.... 732338032Speter Check for the $j macro getting undefined, losing a dot, or getting 732438032Speter lost from $=w in the daemon before accepting a connection; 732538032Speter if it is, it dumps state, prints a LOG_ALERT message, 732638032Speter and drops core for debugging. This is an attempt to 732738032Speter track down a bug that I thought was long since gone. 732838032Speter If you see this, please forward the log fragment to 732938032Speter sendmail@sendmail.ORG. 733038032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 733138032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 733238032Speter Wolfhugel. 733338032Speter Instead of trying to truncate the listen queue for the server 733438032Speter SMTP port when the load average is too high, just close 733538032Speter the port completely and reopen it later as needed. 733638032Speter This ensures that the other end gets a quick "connection 733738032Speter refused" response, and that the connection can be 733838032Speter recovered later. In particular, some socket emulations 733938032Speter seem to get confused if you tweak the listen queue 734038032Speter size around and can never start listening to connections 734138032Speter again. The down side is that someone could start up 734238032Speter another daemon process in the interim, so you could 734338032Speter have multiple daemons all not listening to connections; 734438032Speter this could in turn cause the sendmail.pid file to be 734538032Speter incorrect. A better approach might be to accept the 734638032Speter connection and give a 421 code, but that could break 734743730Speter other mailers in mysterious ways and have paging behavior 734838032Speter implications. 734938032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 735038032Speter set debugging on the wrong socket. From Eric Wassenaar. 735138032Speter When creating a df* temporary file, be sure you truncate any 735238032Speter existing data in the file -- otherwise system crashes 735338032Speter and the like could result in extra data being sent. 735438032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 735538032Speter doc directory. This includes some additional 735638032Speter information. 735738032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 735838032Speter of recipient envelope addresses. This should have been 735938032Speter handled by the $&h trick, but broke if people were 736038032Speter mixing domainized and UUCP addresses. They should 736138032Speter probably have converted all the way over to uucp-uudom 736238032Speter instead of uucp-{new,old}, but the failure mode was to 736338032Speter loop the mail, which was bad news. 736438032Speter Portability fixes: 736538032Speter Newer BSDI systems (several people). 736638032Speter Older BSDI systems from Christophe Wolfhugel. 736738032Speter Intergraph CLIX, from Paul Southworth of CICNet. 736838032Speter UnixWare, from Evan Champion. 736938032Speter NetBSD from Adam Glass. 737038032Speter Solaris from Quentin Campbell of the University of 737138032Speter Newcastle upon Tyne. 737238032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 737338032Speter Corporation. 737438032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 737538032Speter SunOS (it has setsid() and setvbuf() calls) from 737638032Speter Jonathan Kamens of OpenVision Technologies. 737738032Speter HP-UX from Tor Lillqvist. 737838032Speter New Files: 737938032Speter src/Makefile.CLIX 738038032Speter src/Makefile.NCR3000 738138032Speter doc/changes/Makefile 738238032Speter doc/changes/changes.me 738338032Speter doc/changes/changes.ps 738438032Speter 738564562Sgshapiro8.6.8/8.6.6 1994/03/21 738638032Speter SECURITY: it was possible to read any file as root using the 738738032Speter E (error message) option. Reported by Richard Jones; 738838032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 738938032Speter 739064562Sgshapiro8.6.7/8.6.6 1994/03/14 739138032Speter SECURITY: it was possible to get root access by using weird 739238032Speter values to the -d flag. Thanks to Alain Durand of 739338032Speter INRIA for forwarding me the notice from the bugtraq 739438032Speter list. 739538032Speter 739664562Sgshapiro8.6.6/8.6.6 1994/03/13 739738032Speter SECURITY: the ability to give files away on System V-based 739838032Speter systems proved dangerous -- don't run as the owner 739938032Speter of a :include: file on a system that allows giveaways. 740038032Speter Unfortunately, this also applies to determining a 740138032Speter valid shell. 740238032Speter IMPORTANT: Previous versions weren't expiring old connections 740338032Speter in the connection cache for a long time under some 740438032Speter circumstances. This could result in resource exhaustion, 740538032Speter both at your end and at the other end. This checks the 740638032Speter connections for timeouts much more frequently. From 740738032Speter Doug Anderson of NCSC. 740838032Speter Fix a glitch that snuck in that caused programs to be run as 740938032Speter the sender instead of the recipient if the mail was 741038032Speter from a local user to another local user. From 741138032Speter Motonori Nakamura of Kyoto University. 741238032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 741338032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 741438032Speter Bryan Costales of ICSI. 741538032Speter Change the method used to declare the "statfs" availability; 741638032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 741738032Speter tweaking in conf.c, there is a single #define called 741838032Speter SFS_TYPE which takes on one of six values (SFS_NONE 741938032Speter for no statfs availability, SFS_USTAT for the ustat(2) 742038032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 742138032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 742238032Speter statfs(2) call with the declarations in <sys/vfs.h>, 742338032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 742438032Speter Fix glitch in NetInfo support that could return garbage if 742538032Speter there was no "/locations/sendmail" property. From 742638032Speter David Meyer of the University of Virginia. 742738032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 742838032Speter to allow Linux to turn it off even though it is a 742938032Speter BSD-like system. 743038032Speter Allow setting of "ident" timeout to zero to turn off the ident 743138032Speter protocol entirely. 743238032Speter Make 7-bit stripping local to a connection (instead of to a 743338032Speter mailer); this allows you to specify that SMTP is a 743438032Speter 7-bit channel, but revert to 8-bit should it advertise 743538032Speter that it supports 8BITMIME. You still have to specify 743638032Speter mailer flag 7 to get this stripping at all. 743738032Speter Improve makesendmail script so it handles more cases automatically. 743838032Speter Tighten up restrictions on taking ownership of :include: files 743938032Speter to avoid problems on systems that allow you to give away 744038032Speter files. 744138032Speter Fix a problem that made it impossible to rebuild the alias 744238032Speter file if it was on a read-only file system. From 744338032Speter Harry Edmon of the University of Washington. 744438032Speter Improve MX randomization function. From John Gardiner Myers 744538032Speter of CMU. 744638032Speter Fix a minor glitch causing a bogus message to be printed (used 744738032Speter %s instead of %d in a printf string for the line number) 744838032Speter when a bad queue file was read. From Harry Edmon. 744938032Speter Allow $s to remain NULL on locally generated mail. I'm not 745038032Speter sure this is necessary, but a lot of people have complained 745138032Speter about it, and there is a legitimate question as to whether 745238032Speter "localhost" is legal as an 822-style domain. 745338032Speter Fix a problem with very short line lengths (mailer L= flag) in 745438032Speter headers. This causes a leading space to be added onto 745538032Speter continuation lines (including in the body!), and also 745638032Speter tries to wrap headers containing addresses (From:, To:, 745738032Speter etc) intelligently at the shorter line lengths. Problem 745838032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 745938032Speter Log the real user name when logging syserrs, since these can have 746038032Speter security implications. Suggested by several people. 746138032Speter Fix address logging of cached connections -- it used to always 746238032Speter log the numeric address as zero. This is a somewhat 746338032Speter bogus implementation in that it does an extra system 746438032Speter call, but it should be an inexpensive one. Fix from 746538032Speter Motonori Nakamura. 746638032Speter Tighten up handling of short syslog buffers even more -- there 746738032Speter were cases where the outgoing relay= name was too long 746838032Speter to share a line with delay= and mailer= logging. 746938032Speter Limit the overhead on split envelopes to one open file descriptor 747038032Speter per envelope -- previously the overhead was three 747138032Speter descriptors. This was in response to a problem reported 747238032Speter by P{r (Pell) Emanuelsson. 747338032Speter Fixes to better handle the case of unexpected connection closes; 747438032Speter this redirects the output to the transcript so the info 747538032Speter is not lost. From Eric Wassenaar. 747638032Speter Fix potential string overrun if you macro evaluate a string that 747738032Speter has a naked $ at the end. Problem noted by James Matheson 747838032Speter <jmrm@eng.cam.ac.uk>. 747938032Speter Make default error number on $#error messages 553 (``Requested 748038032Speter action not taken: mailbox name not allowed'') instead of 748138032Speter 501 (``Syntax error in parameters or arguments'') to 748238032Speter avoid bogus "protocol error" messages. 748338032Speter Strip off any existing trailing dot on names during $[ ... $] 748438032Speter lookup. This prevents it from ending up with two dots 748538032Speter on the end of dot terminated names. From Wesley Craig 748638032Speter of the University of Michigan and Bryan Costales of ICSI. 748738032Speter Clean up file class reading so that the debugging information is 748838032Speter more informative. It hadn't been using setclass, so you 748938032Speter didn't see the class items being added. 749038032Speter Avoid core dump if you are running a version of sendmail where 749138032Speter NIS is compiled in, and you specify an NIS map, but 749238032Speter NIS is not running. Fix from John Oleynick of 749338032Speter Rutgers. 749438032Speter Diagnose bizarre case where res_search returns a failure value, 749538032Speter but sets h_errno to a success value. 749638032Speter Make sure that "too many hops" messages are considered important 749738032Speter enough to send an error to the Postmaster (that is, the 749838032Speter address specified in the P option). This fix should 749938032Speter help problems that cause the df file to be left around 750038032Speter sometimes -- unfortunately, I can't seem to reproduce 750138032Speter the problem myself. 750238032Speter Avoid core dump (null pointer reference) on EXPN command; this 750338032Speter only occurred if your log level was set to 10 or higher 750438032Speter and the target account was an alias or had a .forward file. 750538032Speter Problem noted by Janne Himanka. 750638032Speter Avoid "denial of service" attacks by someone who is flooding your 750738032Speter SMTP port with bad commands by shutting the connection 750838032Speter after 25 bad commands are issued. From Kyle Jones of 750938032Speter UUNET. 751038032Speter Fix core dump on error messages with very long "to" buffers; 751138032Speter fmtmsg overflows the message buffer. Fixed by trimming 751238032Speter the to address to 203 characters. Problem reported by 751338032Speter John Oleynick. 751438032Speter Fix configuration for HASFLOCK -- there were some spots where 751538032Speter a #ifndef was incorrectly #ifdef. Pointed out by 751638032Speter George Baltz of the University of Maryland. 751738032Speter Fix a typo in savemail() that could cause the error message To: 751838032Speter lists to be incorrect in some places. From Motonori 751938032Speter Nakamura. 752038032Speter Fix a glitch that can cause duplicate error messages on split 752138032Speter envelopes where an address on one of the lists has a 752238032Speter name server failure. Fix from Voradesh Yenbut of the 752338032Speter University of Washington. 752438032Speter Fix possible bogus pointer reference on ESMTP parameters that 752538032Speter don't have an ``=value'' part. 752638032Speter CNAME loops caused an error message to be generated, but also 752738032Speter re-queued the message. Changed to just re-queue the 752838032Speter message (it's really hard to just bounce it because 752938032Speter of the weird way the name server works in the presence 753038032Speter of CNAME loops). Problem noted by James M.R.Matheson 753138032Speter of Cambridge University. 753238032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 753338032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 753438032Speter user name. Suggested by Andreas Stolcke of ICSI. 753538032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 753638032Speter override it easily in the Makefile -- that is, you can 753738032Speter turn it off using -DNAMED_BIND=0. 753838032Speter If a gethostbyname(...) of an address with a trailing dot fails, 753938032Speter try it without the trailing dot. This is because if 754038032Speter you have a version of gethostbyname() that falls back 754138032Speter to NIS or the /etc/hosts file it will fail to find 754238032Speter perfectly reasonable names that just don't happen to 754338032Speter be dot terminated in the hosts file. You don't want to 754438032Speter strip the dot first though because we're trying to ensure 754538032Speter that country names that match one of your subdomains get 754638032Speter a chance. 754738032Speter PRALIASES: fix bogus output on non-null-terminated strings. 754838032Speter From Bill Gianopoulos of Raytheon. 754938032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 755038032Speter This was in code intended to only catch the self-literal 755138032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 755238032Speter IP address), but the code was broken. However, it will 755338032Speter still do this if $M is defined; this is necessary to 755438032Speter get client configurations to work (sigh). Note that this 755538032Speter means that $M overrides :mailname entries in the user 755638032Speter database! Problem noted by Paul Southworth. 755738032Speter CONFIG: Fix definition of Solaris help file location. From 755838032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 755938032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 756038032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 756138032Speter and USENET_MAILER_MAX to tweak the maximum message 756238032Speter size for various mailers. 756338032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 756438032Speter instead of assuming that it is "inews" for consistency 756538032Speter with other mailers. From Michael Corrigan of UC San Diego. 756638032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 756738032Speter qualify the address in the SMTP envelope as user@{relay|hub} 756838032Speter instead of user@$j. From Bill Wisner of The Well. 756938032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 757038032Speter CONFIG: Don't turn off case mapping of user names in the local 757138032Speter mailer for IRIX. This was different than most every other 757238032Speter system. 757338032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 757438032Speter envelope. Noted by Thierry Besancon 757538032Speter <besancon@excalibur.ens.fr>. 757638032Speter CONFIG: Don't include -z by default on uux line -- most systems 757738032Speter don't want it set by default. Pointed out by Philippe 757838032Speter Michel of Thomson CSF. 757938032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 758038032Speter host name was foo.bar.ray.com and you matched against 758138032Speter ".ray.com", the old implementation bound %1 to "bar" 758238032Speter instead of "foo.bar". Also, allow "." in the mailertable 758338032Speter to match anything -- essentially, take over SMART_HOST. 758438032Speter This also moves matching of explicit local host names 758538032Speter before the mailertable so they don't have to be special 758638032Speter cased in the mailertable data. Reported by Bill 758738032Speter Gianopoulos of Raytheon; the fix for the %1 binding 758838032Speter problem was contributed by Nicholas Comanos of the 758938032Speter University of Sydney. 759038032Speter CONFIG: Don't include "root" in class $=L (users to deliver 759138032Speter locally, even if a hub or relay exists) by default. 759238032Speter This is because of the known bug where definition of 759338032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 759438032Speter both and deliver into the local mailbox. 759538032Speter CONFIG: Move up bitdomain and uudomain handling so that they 759638032Speter are done before .UUCP class matching; uudomain was 759738032Speter reported as ineffective before. This also frees up 759838032Speter diversion 8 for future use. Problem reported by Kimmo 759938032Speter Suominen. 760038032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 760138032Speter into host names. As pointed out by Jonathan Kamens, 760238032Speter these are often used because either the forward or reverse 760338032Speter mapping is broken; this translation makes it broken again. 760438032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 760538032Speter Suominen. 760638032Speter Portability fixes: 760738032Speter Unicos from David L. Kensiski of Sterling Software. 760838032Speter DomainOS from Don Lewis of Silicon Systems. 760938032Speter GNU m4 1.0.3 from Karst Koymans of Utrecht University. 761038032Speter Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. 761138032Speter NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. 761238032Speter BSD/386 from Tony Sanders of BSDI. 761338032Speter Apollo from Eric Wassenaar. 761438032Speter DGUX from Doug Anderson. 761538032Speter Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. 761638032Speter NEW FILES: 761738032Speter src/Makefile.DomainOS 761838032Speter src/Makefile.PTX 761938032Speter src/Makefile.SunOS.5.1 762038032Speter src/Makefile.SunOS.5.2 762138032Speter src/Makefile.SunOS.5.x 762238032Speter src/mailq.1 762338032Speter cf/ostype/domainos.m4 762438032Speter doc/op/Makefile 762538032Speter doc/intro/Makefile 762638032Speter doc/usenix/Makefile 762738032Speter 762864562Sgshapiro8.6.5/8.6.5 1994/01/13 762938032Speter Security fix: /.forward could be owned by anyone (the test 763038032Speter to allow root to own any file was backwards). From 763138032Speter Bob Campbell at U.C. Berkeley. 763238032Speter Security fix: group ids were not completely set when programs 763338032Speter were invoked. This caused programs to have group 763438032Speter permissions they should not have had (usually group 763538032Speter daemon instead of their own group). In particular, 763638032Speter Perl scripts would refuse to run. 763738032Speter Security: check to make sure files that are written are not 763838032Speter symbolic links (at least under some circumstances). 763938032Speter Although this does not respond to a specific known 764038032Speter attack, it's just a good idea. Suggested by 764138032Speter Christian Wettergren. 764238032Speter Security fix: if a user had an NFS mounted home directory on 764338032Speter a system with a restricted shell listed in their 764438032Speter /etc/passwd entry, they could still execute any 764538032Speter program by putting that in their .forward file. 764638032Speter This fix prevents that by insisting that their shell 764738032Speter appear in /etc/shells before allowing a .forward to 764838032Speter execute a program or write a file. You can disable 764938032Speter this by putting "*" in /etc/shells. It also won't 765038032Speter permit world-writable :include: files to reference 765138032Speter programs or files (there's no way to disable this). 765243730Speter These behaviors are only one level deep -- for 765338032Speter example, it is legal for a world-writable :include: 765438032Speter file to reference an alias that writes a file, on 765538032Speter the assumption that the alias file is well controlled. 765638032Speter Security fix: root was not treated suspiciously enough when 765738032Speter looking into subdirectories. This would potentially 765838032Speter allow a cracker to examine files that were publicly 765938032Speter readable but in a non-publicly searchable directory. 766038032Speter Fix a problem that causes an error on QUIT on a cached 766138032Speter connection to create problems on the current job. 766238032Speter These are typically unrelated, so errors occur in 766338032Speter the wrong place. 766438032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 766538032Speter runs more responsive to load average, and fixes a 766638032Speter problem that ignored the load average in locally 766738032Speter generated mail. From Eric Wassenaar. 766838032Speter Fix possible core dump on aliases with null LHS. From 766938032Speter John Orthoefer of BB&N. 767038032Speter Revert to using flock() whenever possible -- there are just 767138032Speter too many bugs in fcntl() locking, particularly over 767238032Speter NFS, that cause sendmail to fail in perverse ways. 767338032Speter Fix a bug that causes the connection cache to get confused 767438032Speter when sending error messages. This resulted in 767538032Speter "unexpected close" messages. It should fix itself 767638032Speter on the following queue run. Problem noted by 767738032Speter Liudvikas Bukys of the University of Rochester. 767838032Speter Include $k in $=k as documented in the Install & Op Guide. 767938032Speter This seems odd, but it was documented.... From 768038032Speter Michael Corrigan of UCSD. 768138032Speter Fix problem that caused :include:s from alias files to be 768238032Speter forced to be owned by root instead of daemon 768338032Speter (actually DefUid). From Tim Irvin. 768438032Speter Diagnose unrecognized I option values -- from Mortin Forssen 768538032Speter of the Chalmers University of Technology. 768638032Speter Make "error" mailer work consistently when there is no error 768738032Speter code associated with it -- previously it returned OK 768838032Speter even though there was a real problem. Now it assumes 768938032Speter EX_UNAVAILABLE. 769038032Speter Fix bug that caused the last header line of messages that had 769138032Speter no body and which were terminated with EOF instead of 769238032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 769338032Speter Fix core dump on SMTP mail to programs that failed -- it tried 769438032Speter to go to a "next MX host" when none existed, causing 769538032Speter a core dump. From der Mouse at McGill University. 769638032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 769738032Speter this makes it easier to turn it off (using 769838032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 769938032Speter Fix YP_MASTER_NAME store to use the unupdated result of 770038032Speter gethostname() (instead of myhostname(), which tries 770138032Speter to fully qualify the name) to be consistent with 770238032Speter SunOS. If your hostname is unqualified, this fixes 770338032Speter transfers to slave servers. Bug noted by Keith 770438032Speter McMillan of Ameritech Services, Inc. 770538032Speter Fix Ultrix problem: gethostbyname() can return a very large 770638032Speter (> 500) h_length field, which causes the sockaddr 770738032Speter to be trashed. Use the size of the sockaddr instead. 770838032Speter Fix from Bob Manson of Ohio State. 770938032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 771038032Speter defined -- this confuses gethostbyname on hosts 771138032Speter file lookups, which doesn't understand the trailing 771238032Speter dot convention. 771338032Speter Log SMTP server subprocesses that die with a signal instead 771438032Speter of from a clean exit. 771538032Speter If you don't have option "I" set, don't assume that a DNS 771638032Speter "host unknown" message is authoritative -- it 771738032Speter might still be found in /etc/hosts. 771838032Speter Fix a problem that would cause Deferred: messages to be sent 771938032Speter as the subject of an error message, even though the 772038032Speter actual cause of a message was more severe than that. 772138032Speter Problem noted by Chris Seabrook of OSSI. 772238032Speter Fix race condition in DBM alias file locking. From Kyle 772338032Speter Jones of UUNET. 772438032Speter Limit delivery syslog line length to avoid bugs in some 772538032Speter versions of syslog(3). This adds a new compile time 772638032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 772738032Speter University, which is in turn derived from IDA. 772838032Speter Fix quotes inside of comments in addresses -- previously 772938032Speter it insisted that they be balanced, but the 822 spec 773038032Speter says that they should be ignored. 773138032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 773238032Speter debugging). This also evaluates ruleset 89, if set 773338032Speter (with the null input), and logs the result. This 773438032Speter should be used sparingly, since the rewrite process 773538032Speter is not reentrant. 773638032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 773738032Speter documented in the Bat Book. 773838032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 773938032Speter return an error message and did not requeue the message. 774038032Speter Fix based on code from Roland Dirlewanger of 774138032Speter Reseau Regional Aquarel, Bordeaux, France. 774238032Speter Fix a problem that caused a seg fault if you got a 421 error 774338032Speter code during some parts of connection initialization. 774438032Speter I've only seen this when talking to buggy mailers on 774538032Speter the other end, but it shouldn't give a seg fault in 774638032Speter any case. From Amir Plivatsky. 774738032Speter Fix core dump caused by a ruleset call that returns null. 774838032Speter Fix from Bryan Costales of ICSI. 774938032Speter Full-Name: field was being ignored. Fix from Motonori Nakamura 775038032Speter of Kyoto University. 775138032Speter Fix a possible problem with very long input lines in setproctitle. 775238032Speter From P{r Emanuelsson. 775338032Speter Avoid putting "This is a warning message" out on return receipts. 775438032Speter Suggested by Douglas Anderson. 775538032Speter Detect loops caused by recursive ruleset calls. Suggested by 775638032Speter Bryan Costales. 775738032Speter Initialize non-alias maps during alias rebuilds -- they may be 775838032Speter needed for parsing. Problem noted by Douglas Anderson. 775938032Speter Log sender address even if no message was collected in SMTP 776038032Speter (e.g., if all RCPTs failed). Suggested by Motonori 776138032Speter Nakamura. 776238032Speter Don't reflect the owner-list contents into the envelope sender 776338032Speter address if the value contains ", :, /, or | (to avoid 776438032Speter illegal addresses appearing there). 776538032Speter Efficiency hack for toktype macro -- from Craig Partridge of 776638032Speter BB&N. 776738032Speter Clean up DNS error printing so that a host name is always 776838032Speter included. 776938032Speter Remember to set $i during queue runs. Reported by Stephen 777038032Speter Campbell of Dartmouth University. 777138032Speter If the environment variable HOSTALIASES is set, use it during 777238032Speter canonification as the name of a file with per-user host 777338032Speter translations so that headers are properly mapped. Reported 777438032Speter by Anne Bennett of Concordia University. 777538032Speter Avoid printing misleading error message if SMTP mailer (not 777638032Speter using [IPC]) should die on a core dump. 777738032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 777838032Speter by the other end closing the connection. From 777938032Speter Dave Morrison of Oracle. 778038032Speter Improve several of the error messages printed by "mailq" 778138032Speter to include a host name or other useful information. 778238032Speter Add NetInfo preliminary support for NeXT systems. From Vince 778338032Speter DeMarco. 778438032Speter Fix a glitch that sometimes caused :include:s that pointed to 778538032Speter NFS filesystems that were down to give an "aliasing/ 778638032Speter forwarding loop broken" message instead of queueing 778738032Speter the message for retry. Noted by William C Fenner of 778838032Speter the NRL Connection Machine Facility. 778938032Speter Fix a problem that could cause a core dump if the input sequence 779038032Speter had (or somehow acquired) a \231 character. 779138032Speter Make sure that route-addrs always have <angle brackets> around 779238032Speter them in non-SMTP envelopes (SMTP envelopes already do 779338032Speter this properly). 779438032Speter Avoid weird headers on unbalanced punctuation of the form: 779538032Speter ``Joe User <user)'' -- this caused reference to the 779638032Speter null macro. Fix from Rick McCarty of IO.COM. 779738032Speter Fix a problem that caused an alias "user: user@local.host" to 779838032Speter not have the QNOTREMOTE bit set; this caused configs 779938032Speter to act as if FEATURE(notsticky) was defined even when 780038032Speter it was not. The effect of the problem was to make it 780138032Speter very hard to to set up satellite sites that had a few 780238032Speter local accounts, with everything else forwarded to a 780338032Speter corporate hub. Reported by Detlef Drewanz of the 780438032Speter University of Rostock and Mark Frost of NCD. 780538032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 780638032Speter addresses. This is more efficient (fewer name server 780738032Speter calls) and fixes certain unusual configurations, such 780838032Speter as those that have ruleset 4 do something that is 780938032Speter non-idempotent unless a mailer-specific ruleset did 781038032Speter something else. Problem reported by Brian J. Coan 781138032Speter of the Institute for Global Communications. 781238032Speter Fix the "obsolete argument" routine in main to better understand 781338032Speter new arguments. For example, if you used ``sendmail 781438032Speter -C config -v -q'' it would choke on the -q because 781538032Speter the -C would stop looking for old-format arguments. 781638032Speter Fix the code that was intended to allow two users to forward their 781738032Speter mail to the same program and have them appear unique. 781838032Speter Portability fixes for: 781938032Speter SCO UNIX from Murray Kucherawy. 782038032Speter SCO Open Server 3.2v4 from Philippe Brand. 782138032Speter System V Release 4 from Rick Ellis and others. 782238032Speter OSF/1 from Steve Campbell. 782338032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 782438032Speter of Stoner Associates. 782538032Speter Motorola SysV88 from Kevin Johnson of Motorola. 782638032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 784038032Speter of the config file has moved to /usr/lib 784138032Speter to match the HP-UX version of sendmail. 784238032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 784338032Speter since this is intended only for internal use, the 784438032Speter usual RFC 821/822/1123 rules can be relaxed. The 784538032Speter main point of this is to avoid munging (ugh) UUCP 784638032Speter addresses when relaying internally. 784738032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 784838032Speter syntax addresses delivered via UUCP. Solution 784938032Speter provided by Peter Wemm. 785038032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 785138032Speter zero; it caused double @ signs in addresses. From 785238032Speter Irving Reid of the University of Toronto. 785338032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 785438032Speter from Markku Toijala of ICL Personal Systems Oy. 785538032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 785638032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 785738032Speter that made it hard to recognize your own pseudodomain 785838032Speter names. 785938032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 786038032Speter rather than letting them get "local configuration 786138032Speter error"s. Problem noted by John Gardiner Myers. 786238032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 786338032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 786438032Speter has uucp-dom semantics but old UUCP syntax. This 786538032Speter also permits "uucp-old" as an alias for "uucp" and 786638032Speter "uucp-new" as a synonym for "suucp" for consistency. 786738032Speter CONFIG: add POP mailer support (from Kimmo Suominen 786838032Speter <kim@grendel.lut.fi>). 786938032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 787038032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 787138032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 787238032Speter was set; it would get an additional @masquerade.host 787338032Speter added to the address. Problem noted by Peter Wan 787438032Speter of Georgia Tech. 787538032Speter CONFIG: make sure that the local UUCP name is in $=w. From 787638032Speter Jim Murray of Stratus. 787738032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 787838032Speter mailer flag. Briefly, if you are sending to host 787938032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 788038032Speter "foo!baz" remains "foo!baz", and anything else has 788138032Speter the local name prepended. 788238032Speter CONFIG: portability fixes for HP-UX. 788338032Speter DOC: several minor problems fixed in the Install & Op Guide. 788438032Speter MAKEMAP: fix core dump problem on lines that are too long or 788538032Speter which lack newline.

From Tom Ferrin of UC 788838032Speter San Francisco Computer Graphics Lab. 788938032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 789038032Speter On HP-UX, /etc/sendmail.cf has been moved to 789138032Speter /usr/lib/sendmail.cf to match HP sendmail. 789238032Speter Permissions have been tightened up on world-writable 789338032Speter :include: files and accounts that have shells 789438032Speter that are not listed in /etc/shells. This may 789538032Speter cause some .forward files that have worked 789638032Speter before to start failing. 789738032Speter SIGUSR1 dumps some state to the log. 789838032Speter NEW FILES: 789938032Speter src/Makefile.DGUX 790038032Speter src/Makefile.Dynix 790138032Speter src/Makefile.FreeBSD 790238032Speter src/Makefile.Mach386 790338032Speter src/Makefile.NetBSD 790438032Speter src/Makefile.RISCos 790538032Speter src/Makefile.SCO 790638032Speter src/Makefile.SVR4 790738032Speter src/Makefile.Titan 790838032Speter cf/mailer/pop.m4 790938032Speter cf/ostype/bsdi1.0.m4 791038032Speter cf/ostype/dgux.m4 791138032Speter cf/ostype/dynix3.2.m4 791238032Speter cf/ostype/sco3.2.m4 791338032Speter makemap/Makefile.dist 791438032Speter praliases/Makefile.dist 791538032Speter 791664562Sgshapiro8.6.4/8.6.4 1993/10/31 791738032Speter Repair core-dump problem (write to read-only memory segment) 791838032Speter if you fall back to the return-to-Postmaster case in 791938032Speter savemail. Problem reported by Richard Liu. 792038032Speter Immediately diagnose bogus sender addresses in SMTP. This 792138032Speter makes quite certain that crackers can't use this 792238032Speter class of attack. 792338032Speter Reliability Fix: check return value from fclose() and fsync() 792438032Speter in a few critical places. 792538032Speter Minor problem in initsys() that reversed a condition for 792638032Speter redirecting the output channel on queue runs. It's 792738032Speter not clear this code even does anything. From Eric 792838032Speter Wassenaar of the Dutch National Institute for Nuclear 792938032Speter and High-Energy Physics. 793038032Speter Fix some problems that caused queue runs to do "too much work", 793138032Speter such as double-reading the Errors-To: header. From 793238032Speter Eric Wassenaar. 793338032Speter Error messages on writing the temporary file (including the 793438032Speter data file) were getting suppressed in SMTP -- this 793538032Speter fix causes them to be properly reported. From Eric 793638032Speter Wassenaar. 793738032Speter Some changes to support AF_UNIX sockets -- this will only 793838032Speter really become relevant in the next release, but some 793938032Speter people need it for local patches. From Michael 794038032Speter Corrigan of UC San Diego. 794138032Speter Use dynamically allocated memory (instead of static buffers) 794238032Speter for macros defined in initsys() and settime(); since 794338032Speter these can have different values depending on which 794438032Speter envelope they are in. From Eric Wassenaar. 794538032Speter Improve logging to show ctladdr on to= logging; this tells you 794638032Speter what uid/gid processes ran as. 794738032Speter Fix a problem that caused error messages to be discarded if 794838032Speter the sender address was unparseable for some reason; 794938032Speter this was supposed to fall back to the "return to 795038032Speter postmaster" case. 795138032Speter Improve aliaswait backoff algorithm. 795238032Speter Portability patches for Linux (8.6.3 required another header 795338032Speter file) (from Karl London) and SCO UNIX. 795438032Speter CONFIG: patch prog mailer to not strip host name off of envelope 795538032Speter addresses (so that it matches local again). From 795638032Speter Christopher Davis. 795738032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 795838032Speter this prevents uux from seeing lines with null names like 795938032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 796038032Speter Nakamura of Kyoto University. 796138032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 796238032Speter it shouldn't fail miserably.

It was previously listed as 797538032Speter the current time. Bug reported by Eric Hagberg of 797638032Speter Cornell University Medical College. 797738032Speter If there is an error when writing the body of a message, 797838032Speter don't send the trailing dot and wait for a response 797938032Speter in sender SMTP, as this could cause the connection to 798038032Speter hang up under some bizarre circumstances. From Eric 798138032Speter Wassenaar. 798238032Speter Fix some server SMTP synchronization problems caused when 798338032Speter connections fail during message collection. From 798438032Speter Eric Wassenaar. 798538032Speter Fix a problem that can cause srvrsmtp to reject mail if the 798638032Speter name server is down -- it accepts the RCPT but rejects 798738032Speter the DATA command. Problem reported by Jim Murray of 798838032Speter Stratus. 798938032Speter Fix a problem that can cause core dumps if the config file 799038032Speter incorrectly resolves to a null hostname.

Fix 799638032Speter from Sven-Ove Westberg of the University of Lulea. 799738032Speter Under very odd circumstances, the alias file rebuild code 799838032Speter could get confused as to whether a database was 799938032Speter open or not. 800038032Speter Check "vendor code" on the end of V lines -- this is 800138032Speter intended to provide a hook for vendor-specific 800238032Speter configuration syntax. (This is a "new feature", 800338032Speter but I've made an exception to my rule in a belief 800438032Speter that this is a highly exceptional case.) 800538032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 800638032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 800738032Speter (from Jon Forrest of UC Berkeley) 800838032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 800938032Speter 801064562Sgshapiro8.6.1/8.6 1993/10/08 801138032Speter Portability fixes for A/UX and Encore UMAX V. 801238032Speter Fix error message handling -- if you had a name server down 801338032Speter causing an error during parsing, that message was never 801438032Speter propagated to the queue file. 801538032Speter 801664562Sgshapiro8.6/8.6 1993/10/05 801738032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 801838032Speter conf.h (other systems have the same bug). 801938032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 802038032Speter getdtablesize() instead of sysconf(); a disturbingly 802138032Speter large number of systems defined _SC_OPEN_MAX in the 802238032Speter header files but don't have the syscall. 802338032Speter Another patch to really truly ignore MX records in getcanonname 802438032Speter if trymx == FALSE. 802538032Speter Fix problem that caused the "250 IAA25499 Message accepted for 802638032Speter delivery" message to be omitted if there was an error 802738032Speter in the header of the message (e.g., a bad Errors-To: 802838032Speter line). Pointed out by Michael Corrigan of UCSD. 802938032Speter Announce name of host we are chatting when we get errors; this 803038032Speter is an IDA-ism suggested by Christophe Wolfhugel. 803138032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 803238032Speter Australian Artificial Intelligence Institute), SCO Unix 803338032Speter (from Murray Kucherawy of Hookup Communication Corp.), 803438032Speter NeXT (from Vince DeMarco and myself), Linux (from 803538032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 803638032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 803738032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 803838032Speter Some changes to get around gcc optimizer bugs. From Takahiro 803938032Speter Kanbe. 804038032Speter Fix error recovery in queueup if another tf file of the same 804138032Speter name already exists. Problem stumbled over by Bill 804238032Speter Wisner of The Well. 804338032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 804438032Speter Problem noted by Keith McMillan of Ameritech Services. 804538032Speter Deal with group permissions properly when opening .forward and 804638032Speter :include: files. This relaxes the 8.1C restrictions 804738032Speter slightly more. This includes proper setting of groups 804838032Speter when reading :include: files, allowing you to read some 804938032Speter files that you should be able to read but have previously 805038032Speter been denied unless you owned them or they had "other" 805138032Speter read permission. 805238032Speter Make certain that $j is in $=w (after the .cf is read) so that 805338032Speter if the user is forced to override some silly system, 805438032Speter MX suppression will still work. 805538032Speter Fix a couple of efficiency problems where newstr was double- 805638032Speter calling expensive routines. In at least one case, it 805738032Speter wasn't guaranteed that they would always return the 805838032Speter same result. Problem noted by Christophe Wolfhugel. 805938032Speter Fix null pointer dereference in putoutmsg -- only on an error 806038032Speter condition from a non-SMTP mailer. From Motonori 806138032Speter Nakamura. 806238032Speter Macro expand "C" line class definitions before scanning so that 806338032Speter "CX $Z" works. 806438032Speter Fix problem that caused error message to be sent while still 806538032Speter trying to send the original message if the connection 806638032Speter is closed during a DATA command after getting an error 806738032Speter on an RCPT command (pretty obscure). Problem reported 806838032Speter by John Myers of CMU. 806938032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 807038032Speter term bug. 807138032Speter Fix a nasty bug causing core dumps when returning the "warning: 807238032Speter cannot deliver for N hours -- will keep trying" message; 807343730Speter it only occurred if you had PostmasterCopy set and 807438032Speter only on some architectures. Although sendmail would 807538032Speter keep trying, it would send error messages on each 807638032Speter queue interval. This is an important fix. 807738032Speter Allow u and g options to take user and group names respectively. 807838032Speter Don't do a chdir into the queue directory in -bt mode to make 807938032Speter ruleset testing a bit easier. 808038032Speter Don't allow users to turn off logging (using -oL) on the command 808138032Speter line -- command line can only raise, not lower, logging 808238032Speter level. 808338032Speter Set $u to the original recipient on the SMTP transaction or on 808438032Speter the command line. This is only done if there is exactly 808538032Speter one recipient. Technically, this does not meet the 808638032Speter specs, because it does not guarantee a domain on the 808738032Speter address. 808838032Speter Fix a problem that dumped error messages on bad addresses if 808938032Speter you used the -t flag. Problem noted by Josh Smith of 809038032Speter Harvey Mudd College. 809138032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 809238032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 809338032Speter avoid the problem of people who use angle brackets in 809438032Speter their full name information. 809538032Speter Fix a null pointer dereference if you set option "l", have 809638032Speter an Errors-To: header in the message, and have Errors-To: 809738032Speter defined in the config file H lines. From J.R. Oldroyd. 809838032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 809938032Speter wrong when compiling. Suggested by Rick McCarty of TI. 810038032Speter Fix a problem that could pass negative SIZE parameter if the 810138032Speter df file got lost; this would cause servers to always 810238032Speter give a temporary failure, making the problem even worse. 810338032Speter Problem noted by Allan Johannesen of WPI. 810438032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 810538032Speter protocol timeouts (30s default). Requested by Murray 810638032Speter Kucherawy of HookUp Communication Corp. to handle bogus 810738032Speter PC TCP/IP implementations. 810838032Speter Change $w default definition to be just the first component of 810938032Speter the domain name on config level 5. The $j macro defaults 811038032Speter to the FQDN; $m remains as before. This lets well-behaved 811138032Speter config files use any of the short, long, or subdomain 811238032Speter names. 811338032Speter Add makesendmail script in src to try to automate multi-architecture 811438032Speter builds. I know, this is sub-optimal, but it is still 811538032Speter helpful. 811638032Speter Fix very obscure race condition that can cause a queue run to 811738032Speter get a queue file for an already completed job. This 811838032Speter problem has existed for years. Problem noted by the 811938032Speter long suffering Allan Johannesen of WPI. 812038032Speter Fix a problem that caused the raw sender name to be passed to 812138032Speter udbsender instead of the canonified name -- this caused 812238032Speter it to sometimes miss records that it should have found. 812338032Speter Relax check of name on HELO packet so that a program using -bs 812438032Speter that claims to be itself works properly. 812538032Speter Restore rewriting of $: part of address through 2, R, 4 in 812638032Speter buildaddr -- this requires passing a lot of flags to get 812738032Speter it right. Unlike old versions, this ONLY rewrites 812838032Speter recipient addresses, not sender addresses. 812938032Speter Fix a bug that caused core dumps in config files that cannot 813038032Speter resolve /file/name style addresses. Fix from Jonathan 813138032Speter Kamens of OpenVision Technologies. 813238032Speter Fix problem with fcntl locking that can cause error returns to 813338032Speter be lost if the lock is lost; this required fully 813438032Speter queueing everything, dropping the envelope (so errors 813538032Speter would get returned), and then re-reading the queue from 813638032Speter scratch. 813738032Speter Fix a problem that caused aliases that redefine an otherwise 813838032Speter true address to still send to the original address 813938032Speter if and only if the alias failed in certain bizarre 814038032Speter ways (e.g, if they pointed at a list:; syntax address). 814138032Speter Problem pointed out by Jonathan Kamens. 814238032Speter Remove support for frozen configuration files. They caused 814338032Speter more trouble than it was worth. 814438032Speter Fix problem that can cause error messages to get ignored when 814538032Speter using both -odb and -t flags. Problem noted by Rob 814638032Speter McNicholas at U.C. Berkeley. 814738032Speter Include all "normal" variations on hostname in $=w. For example, 814838032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 814938032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 815038032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 815138032Speter the queue. 815238032Speter Reset SmtpPhase global on initial connection creation so that 815338032Speter messages don't come out with stale information. 815438032Speter Pass an "ext" argument to lockfile so that error/log messages 815538032Speter will properly reflect the true filename being locked. 815638032Speter Put all [...] address forms into $=w -- this eliminates the need 815738032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 815838032Speter Myers of CMU. 815938032Speter Fix a bug that can cause qf files to be left around even after 816038032Speter an SMTP RSET command. Problem and fix from Michael 816138032Speter Corrigan. 816243730Speter Don't send a PostmasterCopy to errors when the Precedence: is 816338032Speter negative. Error reports still go to the envelope 816438032Speter sender address. 816538032Speter Add LA_SHORT for load averages. 816638032Speter Lock sendmail.st file when posting statistics. 816738032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 816838032Speter set the size of the TCP send and receive buffers; if you 816938032Speter run over a slow slip line you may need to set these down 817038032Speter (although it would be better to fix the SLIP implementation 817138032Speter so that it's not necessary to recompile every program 817238032Speter that does bulk data transfer). 817338032Speter Allow null defaults on $( ... $) lookups. Problem reported by 817438032Speter Amir Plivatsky. 817538032Speter Diagnose crufty S and V config lines. This resulted from an 817638032Speter observation that some people were using the SITE macro 817738032Speter without the SITECONFIG macro first, which was causing 817838032Speter bogus config files that were not caught. 817938032Speter Fix makemap -f flag to turn off case folding (it was turning it 818038032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 818138032Speter Fix a problem that caused multiple error messages to be sent if 818238032Speter you used "sendmail -t -oem -odb", your system uses fcntl 818338032Speter locking, and one of the recipient addresses is unknown. 818438032Speter Reset uid earlier in include() so that recursive .forwards or 818538032Speter :include:s don't use the wrong uid. 818638032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 818738032Speter called, the code to recover the descriptor was broken. 818838032Speter This sometimes (only sometimes) caused problems with the 818938032Speter alias file. Fix from Motonori Nakamura. 819038032Speter Fix a problem that caused aliaswait to go into infinite recursion 819138032Speter if the @:@ metasymbol wasn't found in the alias file. 819238032Speter Improve error message on newaliases if database files cannot be 819338032Speter opened or if running with no database format defined. 819438032Speter Do a better estimation of the size of error messages when NoReturn 819538032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 819638032Speter Fix a problem causing the "c" option (don't connect to expensive 819738032Speter mailers) to be ignored in SMTP. Problem noted and the 819838032Speter solution suggested by Robert Elz of The University of 819938032Speter Melbourne. 820038032Speter Improve connection caching algorithm by passing "[host]" to 820138032Speter hostsignature, which strips the square brackets and 820238032Speter returns the real name. This allows mailertable entries 820338032Speter to match regular entries. 820438032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 820538032Speter feature, even if it doesn't work right. 820638032Speter Catch and log attempts to try the "wiz" command in server SMTP. 820738032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 820838032Speter Be more generous at assigning $z to the home directory -- do this 820938032Speter for programs that are specified through a .forward file. 821038032Speter Fix from Andrew Chang of Sun Microsystems. 821138032Speter Always save a fatal error message in preference to a non-fatal 821238032Speter error message so that the "subject" line of return 821338032Speter messages is the best possible. 821438032Speter CONFIG: reduce the number of quotes needed to quote configuration 821538032Speter parameters with commas: two quotes should work now, e.g., 821638032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 821738032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 821838032Speter connections (domain-ized UUCP). 821938032Speter CONFIG: fix bug in default maps (-o must be before database file 822064562Sgshapiro name). Pointed out by Christophe Wolfhugel. 822138032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 822238032Speter DNS. This would presumably be used in UUCP islands. 822338032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 822438032Speter CONFIG: log $u in Received: line. This is in technical violation 822538032Speter of the standards, since it doesn't guarantee a domain 822638032Speter on the address. 822738032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 822838032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 822938032Speter the "m" flag should you want it. Apparently some Solaris 2.2 823038032Speter installations can't handle multiple local recipients. 823138032Speter Problem noted by Josh Smith. 823238032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 823338032Speter CONFIG: change default version level from 4 to 5. 823438032Speter CONFIG: add FEATURE(nullclient) to create a config file that 823538032Speter forwards all mail to a hub without ever looking at the 823638032Speter addresses in any detail. 823738032Speter CONFIG: properly strip mailer: information off of relays when 823838032Speter used to change .BITNET form into %-hack form. 823938032Speter CONFIG: fix a problem that caused infinite loops if presented 824038032Speter with an address such as "!foo". 824138032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 824238032Speter the reverse "PTR" mapping is broken. There's a better 824338032Speter way to do this, but the change is fairly major and I 824438032Speter want to hold it for another release. Problem noted by 824538032Speter Bret Marquis. 824638032Speter 824764562Sgshapiro8.5/8.5 1993/07/23 824838032Speter Serious bug: if you used a command line recipient that was unknown 824938032Speter sendmail would not send a return message (it was treating 825038032Speter everything as though it had an SMTP-style client that 825138032Speter would do the return itself). Problem noted by Josh Smith. 825238032Speter Change "trymx" option in getcanonname() to ignore all MX data, 825338032Speter even during a T_ANY query. This actually didn't break 825438032Speter anything, because the only time you called getcanonname 825538032Speter with !trymx was if you already knew there were no MX 825638032Speter records, but it is somewhat cleaner. From Motonori 825738032Speter Nakamura. 825838032Speter Don't call getcanonname from getmxrr if you already know there 825938032Speter are no DNS records matching the name. 826038032Speter Fix a problem causing error messages to always include "The 826138032Speter original message was received ... from localhost". 826238032Speter The correct original host information is now included. 826338032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 826438032Speter version of "test" doesn't have the -x flag). Change it 826538032Speter to use -f instead. From John Myers. 826638032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 826738032Speter esmtp -- it should be smtp. 826838032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 826938032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 827038032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 827138032Speter this cleans up the configs somewhat. This fixes a serious 827238032Speter problem that caused route-addrs to get mistaken as relays, 827338032Speter pointed out by John Myers. WARNING: this also causes 827438032Speter the default on SMART_HOST to change from "suucp" to 827538032Speter "relay" if you have MAILER(smtp) specified. 827638032Speter 827764562Sgshapiro8.4/8.4 1993/07/22 827838032Speter Add option `w'. If you receive a message that comes to you because 827938032Speter you are the best (lowest preference) target of an MX, and 828038032Speter you haven't explicitly recognized the source MX host in 828138032Speter your .cf file, this option will cause you to try the target 828238032Speter host directly (as if there were no MX for it at all). If 828338032Speter `w' is not set, this case is a configuration error. 828438032Speter Beware: if `w' is set, senders may get bogus errors like 828538032Speter "message timed out" or "host unknown" for problems that 828638032Speter are really configuration errors. This option is 828738032Speter disrecommended, provided only for compatibility with 828838032Speter UIUC sendmail. 828938032Speter Fix a problem that caused the incoming socket to be left open 829038032Speter when sendmail forks after the DATA command. This caused 829138032Speter calling systems to wait in FIN_WAIT_2 state until the 829238032Speter entire list was processed and the child closed -- a 829338032Speter potentially prodigious amount of time. Problem noted 829438032Speter by Neil Rickert. 829538032Speter Fix problem (created in 6.64) that caused mail sent to multiple 829638032Speter addresses, one of which was a bad address, to completely 829738032Speter suppress the sending of the message. This changes 829838032Speter handling of EF_FATALERRS somewhat, and adds an 829938032Speter EF_GLOBALERRS flag. This also fixes a potential problem 830038032Speter with duplicate error messages if there is a syntax error 830138032Speter in the header of a message that isn't noticed until late 830238032Speter in processing. Original problem pointed out by Josh Smith 830338032Speter of Harvey Mudd College. This release includes quite a bit 830438032Speter of dickering with error handling (see below). 830538032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 830638032Speter will only hurt already-broken software and should help 830738032Speter humans. 830838032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 830938032Speter compiled in. It would never read the alias file. 831038032Speter Repair unbalanced `)' and `>' (the "open" versions are already 831138032Speter repaired). 831238032Speter Logging of "done" in dropenvelope() was incorrect: it would 831338032Speter log this even when the queue file still existed. Change 831438032Speter this to only log "done" (at log level 11) when the 831538032Speter queue file is actually removed. From John Myers. 831638032Speter Log "lost connection" in server SMTP at log level 20 if there 831738032Speter is no pending transaction. Some senders just close the 831838032Speter connection rather than sending QUIT. 831938032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 832038032Speter domains that do not have MX records -- this would cause 832138032Speter the subsequent host name lookup to fail. The problem 832238032Speter only occurred if you had FEATURE(nocanonify) set. 832338032Speter Problem noted by Rick McCarty of Texas Instruments. 832438032Speter Fix invocation of setvbuf when passed a -X flag -- I had 832538032Speter unwittingly used an ANSI C extension, and this caused 832638032Speter core dumps on some machines. 832738032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 832838032Speter Previously it just gave an empty send queue, which 832938032Speter then gave either "Need RCPT (recipient)" at the DATA 833038032Speter (confusing, since you had given an RCPT command which 833138032Speter returned 250) or just dropped the email, depending on 833238032Speter whether you were running VERBose mode. Now it usually 833338032Speter diagnoses this case as "aliasing/forwarding loop broken". 833438032Speter Unfortunately, it still doesn't adequately diagnose 833538032Speter some true error conditions. 833638032Speter Add internal concept of "warning messages" using 6xx codes. 833738032Speter These are not reported only to Postmaster. Unbalanced 833838032Speter parens, brackets, and quotes are printed as 653 codes. 833938032Speter They are always mapped to 5xx codes before use in SMTP. 834038032Speter Clean up error messages to tell both the actual address that 834138032Speter failed and the alias they arose from. This makes it 834238032Speter somewhat easier to diagnose problems. Difficulty noted 834338032Speter by Motonori Nakamura. 834438032Speter Fix a problem that inappropriately added a ctladdr to addresses 834538032Speter that shouldn't have had one during a queue run. This 834638032Speter caused error messages to be handled differently during 834738032Speter a queue run than a direct run. 834838032Speter Don't print the qf name and line number if you get errors during 834938032Speter the direct run of the queue from srvrsmtp -- this was 835038032Speter just extra stuff for users to crawl through. 835138032Speter Put command line flags on second line of pid file so you can 835238032Speter auto-restart the daemon with all appropriate arguments. 835338032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 835438032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 835538032Speter restart it. 835638032Speter Remove the ``setuid(getuid())'' in main -- this caused the 835738032Speter IDENT daemon to screw up. This required that I change 835838032Speter HASSETEUID to HASSETREUID and complicate the mode 835938032Speter changing somewhat because both Ultrix and SunOS seem 836038032Speter to have a bug causing seteuid() to set the saved uid 836138032Speter as well as the effective. The program test/t_setreuid.c 836238032Speter will test to see if your implementation of setreuid(2) 836338032Speter is appropriately functional. 836438032Speter The FallBackMX (option V) handling failed to properly identify 836538032Speter fallback to yourself -- most of the code was there, 836638032Speter but it wasn't being enabled. Problem noted by Murray 836738032Speter Kucherawy of the University of Waterloo. 836838032Speter Change :include: open timeout from ETIMEDOUT to an internal 836938032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 837038032Speter with CurHostName" in error messages, which can be 837138032Speter confusing. Reported by Jonathan Kamens of OpenVision 837238032Speter Technologies. 837338032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 837438032Speter process group id. The original fix was to get around 837538032Speter some problems with recalcitrant MUAs, but it breaks 837638032Speter any call from a shell that creates a process group id 837738032Speter different from the process id. I could try to fix 837838032Speter this by diddling the tty owner (using tcsetpgrp or 837938032Speter equivalent) but this is too likely to break other 838038032Speter things. 838138032Speter Portability changes: 838238032Speter Support -M as equivalent to -oM on Ultrix -- apparently 838338032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 838438032Speter instead of using standard flags. Oh joy. This 838543730Speter behavior reported by Jon Giltner of University 838638032Speter of Colorado. 838738032Speter SGI IRIX -- this includes several changes that should 838838032Speter help other strict ANSI compilers. 838938032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 839038032Speter Corporation. 839138032Speter Solaris running the Sun C compiler (which despite the 839238032Speter documentation apparently doesn't define 839338032Speter __STDC__ by default). 839438032Speter ConvexOS from Eric Schnoebelen of Convex. 839538032Speter Sony NEWS workstations and Omron LUNA workstations from 839638032Speter Motonori Nakamura. 839738032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 839838032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 839938032Speter several people have made a good argument that this 840038032Speter creates more problems than it solves (although this 840138032Speter may prove painful in the short run). 840238032Speter CONFIG: generalize all the relays to accept a "mailer:host" 840338032Speter format. 840438032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 840538032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 840638032Speter addresses are also passed through this ruleset. 840738032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 840838032Speter internet-style addresses would "fall off the end" of 840938032Speter ruleset zero and be interpreted as local -- however, 841038032Speter the angle brackets confused the recursive call. 841138032Speter These are now diagnosed as "Unrecognized host name". 841238032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 841338032Speter ifdef(`_MAILER_USENET_') instead of 841438032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 841538032Speter of SINTEF RUNIT, Oslo. 841638032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 841738032Speter early in ruleset 0; this allows .mc authors to bypass 841838032Speter things like the "short circuit" code for local addresses. 841938032Speter Prompted by a comment by Bill Wisner of The Well. 842038032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 842138032Speter esmtp) to send SMTP mail. This allows you to default 842238032Speter to esmtp but use a mailertable or other override to 842338032Speter deal with broken servers. This logic was pointed out 842438032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 842538032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 842638032Speter environments. Ugly as sin. 842738032Speter 842864562Sgshapiro8.3/8.3 1993/07/13 842938032Speter Fix setuid problems introduced in 8.2 that caused messages 843038032Speter like "Cannot create qfXXXXXX: Invalid argument" 843138032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 843238032Speter involved a new compile flag "HASSETEUID" that takes 843338032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 843438032Speter that the POSIX interface is broken enough to break 843538032Speter some systems badly. This includes some fixes for 843638032Speter HP-UX. Also fixes problems where the real uid is 843738032Speter not reset properly on startup (from Neil Rickert). 843838032Speter Fix a problem that caused timed out messages to not report the 843938032Speter addresses that timed out. Error messages are also more 844038032Speter "user friendly". 844138032Speter Drop required bandwidth on connections from 64 bytes/sec to 844238032Speter 16 bytes/sec. 844338032Speter Further Solaris portability changes -- doesn't require the BSD 844438032Speter compatibility library. This also adds a new 844538032Speter "HASGETDTABLESIZE" compile flag which can be used if 844638032Speter you want to use getdtablesize(2) instead of sysconf(2). 844738032Speter These are loosely based on changes from David Meyer at 844838032Speter University of Oregon. This now seems to work, at least 844938032Speter for quick test cases. 845038032Speter Fix a problem that can cause duplicate error messages to be 845138032Speter sent if you are in SMTP, you send to multiple addresses, 845238032Speter and at least one of those addresses is good and points 845338032Speter to an account that has a .forward file (whew!). 845438032Speter Fix a problem causing messages to be discarded if checkcompat() 845538032Speter returned EX_TEMPFAIL (because it didn't properly mark 845638032Speter the "to" address). Problem noted by John Myers. 845738032Speter Fix dfopen to return NULL if the open failed; I was depending 845838032Speter on fdopen(-1) returning NULL, which isn't the case. This 845938032Speter isn't serious, but does result in weird error diagnoses. 846038032Speter From Michael Corrigan. 846138032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 846238032Speter messages sent through UUCP-family mailers. Suggested 846338032Speter by Bill Wisner of The Well. 846438032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 846538032Speter include a "uucp-dom" mailer that uses domain-style 846638032Speter addressing. Suggested by Bill Wisner. 846738032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 846838032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 846938032Speter Christophe Wolfhugel. 847038032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 847138032Speter 847264562Sgshapiro8.2/8.2 1993/07/11 847338032Speter Don't drop out on config file parse errors in -bt mode. 847438032Speter On older configuration files, assume option "l" (use Errors-To 847538032Speter header) for back compatibility. NOTE: this DOES NOT 847638032Speter imply an endorsement of the Errors-To: header in any way. 847738032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 847838032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 847938032Speter SMTP server to give an error on this command, and 848038032Speter logging it in the transcript can be confusing. Fix 848138032Speter from Bill Wisner. 848238032Speter IRIX compatibility changes provided by Dan Rich 848338032Speter <drich@sandman.lerc.nasa.gov>. 848438032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 848538032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 848638032Speter <juo@klinzhai.rutgers.edu> 848738032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 848838032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 848938032Speter match the other flags in that file. 849038032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 849138032Speter Save h_errno in mci struct and improve error message display. 849238032Speter Changes from Eric Wassenaar. 849338032Speter Open /dev/null for the transcript if the create of the xf file 849438032Speter failed; this avoids at least one possible null pointer 849538032Speter reference in very weird cases. From Eric Wassenaar. 849638032Speter Clean up statistics gathering; it was over-reporting because of 849738032Speter forks. From Eric Wassenaar. 849838032Speter Fix problem that causes old Return-Path: line to override new 849938032Speter Return-Path: line (conf.c needs H_FORCE to avoid 850038032Speter re-using old value). From Motonori Nakamura. 850138032Speter Fix broken -m flag in K definition -- even if -m (match only) 850238032Speter was specified, it would still replace the key with the 850338032Speter value. Noted by Rick McCarty of Texas Instruments. 850438032Speter If the name server timed out over several days, no "timed out" 850538032Speter message would ever be sent back. The timeout code 850638032Speter has been moved from markfailure() to dropenvelope() 850738032Speter so that all such failures should be diagnosed. Pointed 850838032Speter out by Christophe Wolfhugel and others. 850938032Speter Relax safefile() constraints: directories in an include or 851038032Speter forward path must be readable by self if the controlling 851138032Speter user owns the entry, readable by all otherwise (e.g., 851238032Speter when reading your .forward file, you have to own and 851338032Speter have X permission in it; everyone needs X permission in 851438032Speter the root and directories leading up to your home); 851538032Speter include files must be readable by anyone, but need not 851638032Speter be owned by you. 851738032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 851838032Speter reading a .forward file; this gets around some problems 851938032Speter on NFS mounts if root permission is not exported and 852038032Speter the user's home directory isn't x'able. 852138032Speter Additional NeXT portability enhancements from Axel Zinser. 852238032Speter Additional HP-UX portability enhancements from Brian Bullen. 852338032Speter Add a timeout around SMTP message writes; this assumes you can 852438032Speter get throughput of at least 64 bytes/second. Note that 852538032Speter this does not impact the "datafinal" default, which 852638032Speter is separate; this is just intended to work around 852738032Speter network clogs that will occur before the final dot 852838032Speter is sent. From Eric Wassenaar. 852938032Speter Change map code to set the "include null" flag adaptively -- 853038032Speter it initially tries both, but if it finds anything 853138032Speter matching without a null it never tries again with a 853238032Speter null and vice versa. If -N is specified, it never 853338032Speter tries without the null and creates new maps with a 853438032Speter null byte. If -O is specified, it never tries with 853538032Speter the null (for efficiency). If -N and -O are specified, 853638032Speter you get -NO (get it?) lookup at all, so this would 853738032Speter be a bad idea. If you don't specify either -N or -O, 853838032Speter it adapts. 853938032Speter Fix recognition of "same from address" so that MH submissions 854038032Speter will insert the appropriate full name information; 854138032Speter this used to work and got broken somewhere along the 854238032Speter way. 854338032Speter Some changes to eliminate some unnecessary SYSERRs in the 854438032Speter log. For example, if you lost a connection, don't 854538032Speter bother reporting that fact on the connection you lost. 854638032Speter Add some "extended debugging" flags to try to track down 854738032Speter why we get occasional problems with file descriptor 854838032Speter one being closed when execing a mailer; it seems to 854938032Speter only happen when there has been another error in the 855038032Speter same transaction. This requires XDEBUG, defined 855138032Speter by default in conf.h. 855238032Speter Add "-X filename" command line flag, which logs both sides of 855338032Speter all SMTP transactions. This is intended ONLY for 855438032Speter debugging bad implementations of other mailers; start 855538032Speter it up, send a message from a mailer that is failing, 855638032Speter and then kill it off and examine the indicated log. 855738032Speter This output is not intended to be particularly human 855838032Speter readable. This also adds the HASSETVBUF compile 855938032Speter flag, defaulted on if your compiler defines __STDC__. 856038032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 856138032Speter have a local net that should get direct connects, you 856238032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 856338032Speter See cf/README for an example. 856438032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 856538032Speter sites that don't use the -d flag. 856638032Speter CONFIG: hide recipient addresses as well as sender addresses 856738032Speter behind $M if FEATURE(allmasquerade) is specified; this 856838032Speter has been requested by several people, but can break 856938032Speter local aliases. For example, if you mail to "localalias" 857038032Speter this will be rewritten as "localalias@masqueradehost"; 857138032Speter although initial delivery will work, replies will be 857238032Speter broken. Use it sparingly. 857338032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 857438032Speter to qualified domains in headers. I believe this is 857538032Speter largely equivalent to the IDA feature of the same name. 857638032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 857738032Speter to override the "system name" as your UUCP name -- 857838032Speter in particular, to use domain-ized UUCP names. From 857938032Speter Bill Wisner of The Well. 858038032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 858138032Speter first. This is currently unused in the config files, 858238032Speter but could be used in a mailertable entry. 858338032Speter 858464562Sgshapiro8.1C/8.1B 1993/06/27 858538032Speter Serious security bug fix: it was possible to read any file on 858638032Speter the system, regardless of ownership and permissions. 858738032Speter If a subroutine returns a fully qualified address, return it 858838032Speter immediately instead of feeding it back into rewriting. 858938032Speter This fixes a problem with mailertable lookups. 859038032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 859138032Speter 859264562Sgshapiro8.1B/8.1A 1993/06/12 859338032Speter Serious bug fix: pattern matching backup algorithm stepped by 859438032Speter two tokens in classes instead of one.
