Be sure to read the "FILE AND MAP PERMISSIONS" 1398121Sgshapiro section of the top level README for more information. 1498121Sgshapiro Problem noted by lumpy. 1598121Sgshapiro Use TempFileMode (defaults to 0600) for the permissions of PidFile 1698121Sgshapiro instead of 0644. 1798121Sgshapiro Change the default file permissions for new alias database files 1898121Sgshapiro from 0644 to 0640. This can be overridden at compile time 1998121Sgshapiro by setting the DBMMODE macro. 2098121Sgshapiro Fix a potential core dump problem if the environment variable 2198121Sgshapiro NAME is set. Problem noted by Beth A. Chaney of 2298121Sgshapiro Purdue University. 2398121Sgshapiro Expand macros before passing them to libmilter. Problem noted 2498121Sgshapiro by Jose Marcio Martins da Cruz of Ecole Nationale 2598121Sgshapiro Superieure des Mines de Paris. 2698121Sgshapiro Rewind the df (message body) before truncating it when libmilter 2798121Sgshapiro replaces the body of a message. Problem noted by Gisle Aas 2898121Sgshapiro of Active State. 2998121Sgshapiro Change SMTP reply code for AUTH failure from 500 to 535 and the 3098121Sgshapiro initial zero-length response to "=" per RFC 2554. Patches 3198121Sgshapiro from Kenneth Murchison of Oceana Matrix Ltd. 3298121Sgshapiro Do not try to fix broken message/rfc822 MIME attachments by 3398121Sgshapiro inserting a MIME-Version: header when MaxMimeHeaderLength 3498121Sgshapiro is set and no 8 to 7 bit conversion is needed. Based on 3598121Sgshapiro patch from Rehor Petr of ICZ (Czech Republic). 3698121Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" if the connection 3798121Sgshapiro is rejected anyway. Noted by Chris Loelke. 3898121Sgshapiro Mention the submission mail queue in the mailq man page. Requested 3998121Sgshapiro by Bill Fenner of AT&T. 4098121Sgshapiro Set ${msg_size} macro when reading a message from the command line 4198121Sgshapiro or the queue. 4298121Sgshapiro Detach from shared memory before dropping privileges back to 4398121Sgshapiro user who started sendmail. 4498121Sgshapiro If AllowBogusHELO is set to false (default) then also complain if 4598121Sgshapiro the argument to HELO/EHLO contains white space. Suggested 4698121Sgshapiro by Seva Gluschenko of Cronyx Plus. 4798121Sgshapiro Allow symbolicly linked forward files in writable directory paths 4898121Sgshapiro if both ForwardFileInUnsafeDirPath and 4998121Sgshapiro LinkedForwardFileInWritableDir DontBlameSendmail options 5098121Sgshapiro are set. Problem noted by Werner Spirk of 5198121Sgshapiro Leibniz-Rechenzentrum Munich. 5298121Sgshapiro Portability: 5398121Sgshapiro Operating systems that lack the ftruncate() call will not 5498121Sgshapiro be able to use Milter's body replacement feature. 5598121Sgshapiro This only affects Altos, Maxion, and MPE/iX. 5698121Sgshapiro Digital UNIX 5.0 has changed flock() semantics to be 5798121Sgshapiro non-compliant. Problem noted by Martin Mokrejs of 5898121Sgshapiro Charles University in Prague. 5998121Sgshapiro The sparc64 port of FreeBSD 5.0 now supports shared 6098121Sgshapiro memory. 6198121Sgshapiro CONFIG: FEATURE(`preserve_luser_host') needs the macro map. 6298121Sgshapiro Problem noted by Andrzej Filip. 6398121Sgshapiro CONFIG: Using 'local:' as a mailertable value with 6498121Sgshapiro FEATURE(`preserve_luser_host') and LUSER_RELAY caused mail 6598121Sgshapiro to be misaddressed. Problem noted by Andrzej Filip. 6698121Sgshapiro CONFIG: Provide a workaround for DNS based rejection lists that 6798121Sgshapiro fail for AAAA queries. Problem noted by Chris Boyd. 6898121Sgshapiro CONFIG: Accept the machine's hostname as resolvable when checking 6998121Sgshapiro the sender address. This allows locally submitted mail to 7098121Sgshapiro be accepted if the machine isn't connected to a nameserver 7198121Sgshapiro and doesn't have an /etc/hosts entry for itself. Problem 7298121Sgshapiro noted by Robert Watson of the TrustedBSD Project. 7398121Sgshapiro CONFIG: Use deferred expansion for checking the ${deliveryMode} 7498121Sgshapiro macro in case the SMTP VERB command is used. Problem 7598121Sgshapiro noted by Bryan Costales. 7698121Sgshapiro CONFIG: Avoid a duplicate '@domain' virtusertable lookup if no 7798121Sgshapiro matches are found. Fix from Andrzej Filip. 7898121Sgshapiro CONFIG: Fix wording in default dnsbl rejection message. Suggested 7998121Sgshapiro by Lou Katz of Metron Computerware, Ltd. 8098121Sgshapiro CONFIG: Add mailer cyrusv2 for Cyrus V2. Contributed by 8198121Sgshapiro Kenneth Murchison of Oceana Matrix Ltd. 8298121Sgshapiro CONTRIB: Fix wording in default dnsblaccess rejection message to 8398121Sgshapiro match dnsbl change. 8498121Sgshapiro DEVTOOLS: Add new option for access mode of statistics file, 8598121Sgshapiro confSTMODE, which specifies the permissions when initially 8698121Sgshapiro installing the sendmail statistics file. 8798121Sgshapiro LIBMILTER: Mark the listening socket as close-on-exec in case 8898121Sgshapiro a user's filter starts other applications. 8998121Sgshapiro LIBSM: Allow the MBDB initialize, lookup, and/or terminate 9098121Sgshapiro functions in SmMbdbTypes to be set to NULL. 9198121Sgshapiro MAKEMAP: Change the default file permissions for new databases from 9298121Sgshapiro 0644 to 0640. This can be overridden at compile time 9398121Sgshapiro by setting the DBMMODE macro. 9498121Sgshapiro SMRSH: Fix man page bug: replace SMRSH_CMDBIN with SMRSH_CMDDIR. 9598121Sgshapiro Problem noted by Dave Alden of Ohio State University. 9698121Sgshapiro VACATION: When listing the vacation database (-l), don't show 9798121Sgshapiro bogus timestamps for excluded (-x) addresses. Problem 9898121Sgshapiro noted by Bryan Costales. 9998121Sgshapiro New Files: 10098121Sgshapiro cf/mailer/cyrusv2.m4 10198121Sgshapiro 10294334Sgshapiro8.12.3/8.12.3 2002/04/05 10394334Sgshapiro NOTICE: In general queue files should not be moved if queue groups 10494334Sgshapiro are used. In previous versions this could cause mail 10594334Sgshapiro not to be delivered if a queue file is repeatedly moved 10694334Sgshapiro by an external process whenever sendmail moved it back 10794334Sgshapiro into the right place. Some precautions have been taken 10894334Sgshapiro to avoid moving queue files if not really necessary. 10994334Sgshapiro sendmail may use links to refer to queue files and it 11094334Sgshapiro may store the path of data files in queue files. Hence 11194334Sgshapiro queue files should not be moved unless those internals 11294334Sgshapiro are understood and the integrity of the files is not 11394334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 11494334Sgshapiro University. 11594334Sgshapiro If an error mail is created, and the mail is split across different 11694334Sgshapiro queue directories, and SuperSafe is off, then write the mail 11794334Sgshapiro to disk before splitting it, otherwise an assertion is 11894334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 11994334Sgshapiro of INTERMETA. 12094334Sgshapiro Fix possible race condition that could cause sendmail to forget 12194334Sgshapiro running queues. Problem noted by Jeff Wasilko of smoe.org. 12294334Sgshapiro Handle bogus qf files better without triggering assertions. 12394334Sgshapiro Problem noted by Guy Feltin. 12494334Sgshapiro Protect against interrupted select() call when enforcing Milter 12594334Sgshapiro read and write timeouts. Patch from Gurusamy Sarathy of 12694334Sgshapiro ActiveState. 12794334Sgshapiro Matching queue IDs with -qI should be case sensitive. Problem 12894334Sgshapiro noted by Anne Bennett of Concordia University. 12994334Sgshapiro If privileges have been dropped, don't try to change group ID to 13094334Sgshapiro the RunAsUser group. Problem noted by Neil Rickert of 13194334Sgshapiro Northern Illinois University. 13294334Sgshapiro Fix SafeFileEnvironment path munging when the specified path 13394334Sgshapiro contains a trailing slash. Based on patch from Dirk Meyer 13494334Sgshapiro of Dinoex. 13594334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 13694334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 13794334Sgshapiro Polytechnic Institute. 13894334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 13994334Sgshapiro if several mails are sent in one session and some of them 14094334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 14194334Sgshapiro Change timeout check such that cached information about a connection 14294334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 14394334Sgshapiro Based on patch from David Burns of Portland State University. 14494334Sgshapiro Properly count message size for mailstats during mail collection. 14594334Sgshapiro Problem noted by Werner Wiethege. 14694334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 14794334Sgshapiro patch from by Motonori Nakamura of Kyoto University. 14894334Sgshapiro Provide workaround for getopt() implementations that do not catch 14994334Sgshapiro missing arguments. 15094334Sgshapiro Fix the message size calculation if the message body is replaced by 15194334Sgshapiro a milter filter and buffered file I/O is being used. 15294334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 15394334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 15494334Sgshapiro Problem noted by Werner Wiethege. 15594334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 15694334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 15794334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 15894334Sgshapiro Properly deal with a case where sendmail is called by root running 15994334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 16094334Sgshapiro Lusky of ISS Atlanta. 16194334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 16294334Sgshapiro directories are used and mail is sent to a mailing list 16394334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 16494334Sgshapiro of Concordia University. 16594334Sgshapiro Fix class map parsing code if optional key is specified. Problem 16694334Sgshapiro found by Mario Nigrovic. 16794334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 16894334Sgshapiro incoming messages. A leading dot is always stripped by the 16994334Sgshapiro SMTP receiver regardless of whether or not it is followed by 17094334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 17194334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 17294334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 17394334Sgshapiro Elvers. 17494334Sgshapiro Correct the statistics gathered for total number of connections. 17594334Sgshapiro Instead of being the exact same number as the total number 17694334Sgshapiro of messages (T line in mailstats) it now represents the 17794334Sgshapiro total number of TCP connections. 17894334Sgshapiro Be more explicit about syntax errors in addresses, especially 17994334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 18094334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 18194334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 18294334Sgshapiro are used. Problem noted by Suresh Ramasubramanian. 18394334Sgshapiro Prevent a race condition on child cleanup for delivery to files. 18494334Sgshapiro Problem noted by Fletcher Mattox of the University of 18594334Sgshapiro Texas. 18694334Sgshapiro Change the SMTP error code for temporary map failures from 421 18794334Sgshapiro to 451. 18894334Sgshapiro Do not assume that realloc(NULL, size) works on all OS (this was 18994334Sgshapiro only done in one place: queue group creation). Based on 19094334Sgshapiro patch by Bryan Costales. 19194334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 19294334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 19394334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 19494334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 19594334Sgshapiro errors. By doing so, the host was marked as having a 19694334Sgshapiro temporary problem and other mail destined for that host was 19794334Sgshapiro queued for the next queue run. Problem noted by Fletcher 19894334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 19994334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 20094334Sgshapiro and Neil Rickert of Northern Illinois University. 20194334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 20294334Sgshapiro which drop the connection instead of responding to the 20394334Sgshapiro command). 20494334Sgshapiro Portability: 20594334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 20698121Sgshapiro available. 20794334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 20894334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 20994334Sgshapiro settings. Patch from Elias Halldor Agustsson of 21094334Sgshapiro Skyrr. 21194334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 21294334Sgshapiro noted by John Beck. 21394334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 21494334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 21594334Sgshapiro Rajesh Somasund of Hewlett-Packard. 21694334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 21794334Sgshapiro SMTP AUTH information. This feature was actually added in 21894334Sgshapiro 8.12.0 but a release note was not included. 21994334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 22094334Sgshapiro parameter is set and the LDAP lookup returns a temporary 22194334Sgshapiro error. 22294334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 22394334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 22494334Sgshapiro Krzysztof Oledzki. 22594334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 22694334Sgshapiro initialization as aliases are not needed for the MSP. 22794334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 22894334Sgshapiro is in use. Patch from Andrzej Filip. 22994334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 23094334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 23194334Sgshapiro This will only have an effect if a parameter is specified, 23294334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 23394334Sgshapiro it is embedded in square brackets. Problem noted by 23494334Sgshapiro Theo Van Dinter of Collective Technologies. 23594334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 23694334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 23794334Sgshapiro to allow for the proper time zone on systems where the 23894334Sgshapiro default results in misleading time stamps. That is, syslog 23994334Sgshapiro time stamps and Date headers on submitted mail will use the 24094334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 24194334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 24294334Sgshapiro by Neil Rickert of Northern Illinois University. 24394334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 24494334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 24594334Sgshapiro noted by John Beck. 24694334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 24794334Sgshapiro if queue groups are used. 24894334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 24994334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 25094334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 25194334Sgshapiro Suggested by Bryan Costales. 25294334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 25394334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 25494334Sgshapiro structure that is passed to xxfi_connect(). Notice: 25598121Sgshapiro this fix requires that sendmail and libmilter both have 25698121Sgshapiro this change; mixing versions may lead to wrong port 25794334Sgshapiro values depending on the endianness of the involved systems. 25894334Sgshapiro Problem noted by Gisle Aas of ActiveState. 25994334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 26094334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 26194334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 26294334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 26394334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 26494334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 26594334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 26694334Sgshapiro this to 1 if your LDAP client libraries include 26794334Sgshapiro ldap_memfree(). 26894334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 26994334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 27094334Sgshapiro SMRSH: Fix compilation problem on some operating systems. Problem 27194334Sgshapiro noted by Christian Krackowizer of schuler technodat GmbH. 27294334Sgshapiro VACATION: Allow root to operate on user vacation databases. Based 27394334Sgshapiro on patch from Greg Couch of the University of California, 27494334Sgshapiro San Francisco. 27594334Sgshapiro VACATION: Don't ignore -C option. Based on patch by Bryan Costales. 27694334Sgshapiro VACATION: Clarify option usage in the man page. Problem noted by 27794334Sgshapiro Joe Barbish. 27894334Sgshapiro New Files: 27994334Sgshapiro libmilter/docs/smfi_setbacklog.html 28094334Sgshapiro 28190792Sgshapiro8.12.2/8.12.2 2002/01/13 28290792Sgshapiro Don't complain too much if stdin, stdout, or stderr are missing 28390792Sgshapiro at startup, only log an error message. 28490792Sgshapiro Fix potential problem if an unknown operation mode (character 28590792Sgshapiro following -b) has been specified. 28690792Sgshapiro Prevent purgestat from looping even if someone changes the 28790792Sgshapiro permissions or owner of hoststatus files. Problem noted 28890792Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 28990792Sgshapiro Properly record dropped connections in persistent host status. 29090792Sgshapiro Problem noted by Ulrich Windl of the Universitat 29190792Sgshapiro Regensburg. 29290792Sgshapiro Remove newlines from recipients read via sendmail -t to prevent 29390792Sgshapiro SMTP protocol errors when sending the RCPT command. 29490792Sgshapiro Problem noted by William D. Colburn of the New Mexico 29590792Sgshapiro Institute of Mining and Technology. 29690792Sgshapiro Only log milter body replacements once instead of for each body 29790792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 29890792Sgshapiro the Finnish Meteorological Institute. 29990792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 30090792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 30190792Sgshapiro of the Finnish Meteorological Institute. 30290792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 30390792Sgshapiro needs to collect children status to avoid zombie processes. 30490792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 30590792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 30690792Sgshapiro commands are issued. This makes it consistent with normal 30790792Sgshapiro SMTP connections. 30890792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 30990792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 31090792Sgshapiro and Technology. 31190792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 31290792Sgshapiro message sender if the sender had used a deprecated RFC822 31390792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 31490792Sgshapiro Meteorological Institute. 31590792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 31690792Sgshapiro parsing. Problem noted by Jorg Bielak from Coastal Web 31790792Sgshapiro Online. 31890792Sgshapiro For systems on which stat(2) does not return a value for st_blksize 31990792Sgshapiro that is the "optimal blocksize for I/O" three new compile 32090792Sgshapiro time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF, 32190792Sgshapiro and SM_IO_MAX_BUF, which define an upper limit for 32290792Sgshapiro regular files, and a lower and upper limit for other file 32390792Sgshapiro types, respectively. 32490792Sgshapiro Fix a potential deadlock if two events are supposed to occur at 32590792Sgshapiro exactly the same time.

Patch from David Powell 33890792Sgshapiro of Sun Microsystems. 33990792Sgshapiro Allow specification of an empty realm via the authinfo ruleset. 34090792Sgshapiro This is necessary to interoperate as an SMTP AUTH client 34190792Sgshapiro with servers that do not support realms when using 34290792Sgshapiro CRAM-MD5. Problem noted by Bjoern Voigt of TU Berlin. 34390792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 34490792Sgshapiro server gets stuck while processing that command. Problem 34590792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 34690792Sgshapiro In addition to printing errors when parsing recipients during 34790792Sgshapiro command line invocations log them to make it simpler 34890792Sgshapiro to understand possible DSNs to postmaster. 34990792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 35090792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 35190792Sgshapiro instead of forcing localhost. 35290792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 35390792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 35490792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 35590792Sgshapiro noted by Neil Rickert of Northern Illinois University. 35690792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 35790792Sgshapiro dropping the connection during an SMTP transaction, stop 35890792Sgshapiro sending commands. This prevents bogus "Bad file number" 35990792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 36090792Sgshapiro Worcester Polytechnic Institute. 36190792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 36290792Sgshapiro almost always too small; do not guess the size at all. 36390792Sgshapiro New VENDOR_DEC for Compaq/DEC.

Problem 44190792Sgshapiro found by Michal Zalewski. 44290792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 44390792Sgshapiro privileges by disabling debugging (command line -d flag) 44490792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 44590792Sgshapiro used. Suggested by Michal Zalewski. 44690792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 44790792Sgshapiro Problem found by Michal Zalewski. 44890792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 44990792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 45090792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 45190792Sgshapiro If debugging is turned on (-d0.10) print not just the default 45290792Sgshapiro values for configuration file and pid file but also the 45390792Sgshapiro selected values. Problem noted by Brad Chapman. 45490792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 45590792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 45690792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 45790792Sgshapiro this only applied to hostname canonification. Problem 45890792Sgshapiro noted by Bill Fenner of AT&T Research. 45990792Sgshapiro Ignore comments in NIS host records when trying to find the 46090792Sgshapiro canonical name for a host. 46190792Sgshapiro When sendmail has extra privileges, limit mail submission command 46290792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 46390792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.).

You need to create a new user and 50690792Sgshapiro a new group before installing sendmail (both called smmsp by 50790792Sgshapiro default). The installation process tries to install 50890792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 50990792Sgshapiro default.

Suggested 52090792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 52190792Sgshapiro (IdS). 52290792Sgshapiro Fixed problem of a global variable being used for a timeout jump 52390792Sgshapiro point where the variable could become overused for more than 52490792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 52590792Sgshapiro a corrupted stack causing a core dump. The timeout is now 52690792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 52790792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 52890792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 52990792Sgshapiro checks (group ID of RunAsUser). This allows use of a 53090792Sgshapiro set-group-ID sendmail binary for initial message submission 53190792Sgshapiro and no set-user-ID root sendmail is needed. For details 53290792Sgshapiro see sendmail/SECURITY. 53390792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 53490792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 53590792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 53690792Sgshapiro with a fallback of sendmail.cf as configuration file. See 53790792Sgshapiro sendmail/SECURITY. 53890792Sgshapiro New configuration file option UseMSP to allow group writable queue 53990792Sgshapiro files if the group is the same as that of a set-group-ID 54090792Sgshapiro sendmail binary. See sendmail/SECURITY. 54190792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 54290792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 54390792Sgshapiro is sendmail.cf (to be backward compatible). This selection 54490792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 54590792Sgshapiro file: client or mta). See sendmail/SECURITY. 54690792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 54790792Sgshapiro command has been removed. 54890792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 54990792Sgshapiro at compile time or per host (ruleset). 55090792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 55190792Sgshapiro used to look up local mail recipients; the default value 55290792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 55390792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 55490792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 55590792Sgshapiro long, to accomodate envelope splitting. File systems with 55690792Sgshapiro a 14 character file name length limit are no longer 55790792Sgshapiro supported. 55890792Sgshapiro Recipient list used for delivery now gets internally ordered by 55990792Sgshapiro hostsignature (character string version of MX RR). This orders 56090792Sgshapiro recipients for the same MX RR's together meaning smaller 56190792Sgshapiro portions of the list need to be scanned (instead of the whole 56290792Sgshapiro list) each delivery() pass to determine piggybacking. The 56390792Sgshapiro significance of the change is better the larger the recipient 56490792Sgshapiro list. Hostsignature is now created during recipient list 56590792Sgshapiro creation rather than just before delivery. 56690792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 56790792Sgshapiro piggybacking (called coincidental) extended to coattail 56890792Sgshapiro piggybacking. Rather than complete MX RR matching 56990792Sgshapiro (coincidental) piggybacking is done if just the lowest value 57090792Sgshapiro preference matches (coattail). 57190792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 57290792Sgshapiro try other MX hosts if available. 57390792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 57490792Sgshapiro outgoing (client-side) SMTP Authentication. 57590792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 57690792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 57790792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 57890792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 57990792Sgshapiro A new ruleset authinfo can be used to return client side 58090792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 58190792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 58290792Sgshapiro removed in future versions. 58390792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 58490792Sgshapiro requires 334. Mercury 1.48 is a known offender. 58590792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 58690792Sgshapiro for the security layer in SMTP AUTH (SASL). See 58790792Sgshapiro doc/op/op.me for details. 58890792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 58990792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 59090792Sgshapiro signed the presented certificate, the CN and the MD5 hash 59190792Sgshapiro of the presented certificate, respectively. 59290792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 59390792Sgshapiro New ruleset srv_features to enable/disable certain features in the 59490792Sgshapiro server per connection. See doc/op/op.me for details. 59590792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 59690792Sgshapiro recipient; useful to decide whether a conection is secure 59790792Sgshapiro enough on a per recipient basis. 59890792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 59990792Sgshapiro for STARTTLS. 60090792Sgshapiro If no certificate has been requested, the macro {verify} has the 60190792Sgshapiro value "NOT". 60290792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 60390792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 60490792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 60590792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 60690792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 60790792Sgshapiro really required. This change results in a noticable 60890792Sgshapiro performance gains on most machines. Moreover, if shared 60990792Sgshapiro memory is in use, reuse the key several times. 61090792Sgshapiro Add queue groups which can be used to group queue directories with 61190792Sgshapiro the same behavior together. See doc/op/op.me for details. 61290792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 61390792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 61490792Sgshapiro are initially sorted which may result in faster envelope 61590792Sgshapiro splitting. If the mail is submitted directly from the 61690792Sgshapiro command line, then the value also limits the number of 61790792Sgshapiro processes to deliver the envelopes; if more envelopes are 61890792Sgshapiro created they are only queued up and must be taken care of 61990792Sgshapiro by a queue run. 62090792Sgshapiro The check for 'enough disk space' now pays attention to which file 62190792Sgshapiro system each queue directory resides in. 62290792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 62390792Sgshapiro New option QueueFileMode for the default permissions of queue files. 62490792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 62590792Sgshapiro group (one or more queues in a multi-queue environment 62690792Sgshapiro collected together) to process the same work list at the 62790792Sgshapiro same time. 62890792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 62990792Sgshapiro active queue runner processes. 63090792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 63190792Sgshapiro runners per queue group. 63290792Sgshapiro Queue member selection by substring pattern matching now allows 63390792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 63490792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 63590792Sgshapiro of the queue that match during processing. 63690792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 63790792Sgshapiro periodically forking a child to process the queue, a single 63890792Sgshapiro child is forked for each queue that sleeps between queue 63990792Sgshapiro runs. A SIGHUP signal can be sent to restart this 64090792Sgshapiro persistent queue runner. 64190792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 64290792Sgshapiro sendmail process which only runs the queue at an interval: 64390792Sgshapiro sendmail -q15m). 64490792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 64590792Sgshapiro Proposed by Thom O'Connor. 64690792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 64790792Sgshapiro unless the new -qf option or -v is used. 64890792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 64990792Sgshapiro several queue runners are started by hand to avoid contention. 65090792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 65190792Sgshapiro of the qf file (older entries first). 65290792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 65390792Sgshapiro a client to specify an amount of time within which an e-mail 65490792Sgshapiro should be delivered. New option DeliverByMin added to set the 65590792Sgshapiro minimum amount of time or disable the extension. 65690792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 65790792Sgshapiro not allowed unless escaped or quoted. 65890792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 65990792Sgshapiro by Leif Johansson of Stockholm University, which was based on 66090792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 66190792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 66290792Sgshapiro Technology, Stockholm, Sweden. 66390792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 66490792Sgshapiro behavior (no MX lookups), put the name in square brackets. 66590792Sgshapiro Proposed by Thom O'Connor. 66690792Sgshapiro Use shared memory to store free space of filesystems that are used 66790792Sgshapiro for queues, if shared memory is available and if a key is set 66890792Sgshapiro via SharedMemoryKey. This minimizes the number of system 66990792Sgshapiro calls to check the available space. See doc/op/op.me for 67090792Sgshapiro details. 67190792Sgshapiro If shared memory is compiled in the option -bP can be used to print 67290792Sgshapiro the number of entries in the queue(s). 67390792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 67490792Sgshapiro and the usual documentation for details. 67590792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 67690792Sgshapiro Remove '-U' (initial user submission) command line option as 67790792Sgshapiro announced in 8.10. 67890792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 67990792Sgshapiro New macro {addr_type} which contains whether the current address is 68090792Sgshapiro an envelope sender or recipient address. Suggested by 68190792Sgshapiro Neil Rickert of Northern Illinois University. 68290792Sgshapiro Two new options for host maps: -d (retransmission timeout), 68390792Sgshapiro -r (number of retries). 68490792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 68590792Sgshapiro separator such that a lookup can return both an attribute 68690792Sgshapiro and value separated by the given separator. 68790792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 68890792Sgshapiro to map class arith. 68990792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 69090792Sgshapiro (errors that occur when sending an error message) are dropped. 69190792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 69290792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 69390792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 69490792Sgshapiro requirements for files containing secret keys. This is 69590792Sgshapiro necessary for the MSP if client authentification is used. 69690792Sgshapiro Properly handle quoted filenames for class files (to allow for 69790792Sgshapiro filenames with spaces). 69890792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 69990792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 70090792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 70190792Sgshapiro {if_addr_out} address of interface of outgoing connection. 70290792Sgshapiro {if_family_out} family of interface of outgoing connection. 70390792Sgshapiro The latter two are only set if the interface does not belong 70490792Sgshapiro to the loopback net. 70590792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 70690792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 70790792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 70890792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 70990792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 71090792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 71190792Sgshapiro all connections for a single delivery attempt to succeed. 71290792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 71390792Sgshapiro a threshold number of recipients has been rejected (option 71490792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 71590792Sgshapiro Development Group. 71690792Sgshapiro New option DelayLA to delay connections if the load averages 71790792Sgshapiro exceeds the specified value. The default of 0 does not 71890792Sgshapiro change the previous behavior. A value greater than 0 71990792Sgshapiro will cause sendmail to sleep for one second on most 72090792Sgshapiro SMTP commands and before accepting connections if that 72190792Sgshapiro load average is exceeded. 72290792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 72390792Sgshapiro recipients that are sent during a connection to a mailer. 72490792Sgshapiro This also introduces a new mailer field 'r' which defines 72590792Sgshapiro the maximum number of recipients (defaults to 100). 72690792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 72790792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 72890792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 72990792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 73090792Sgshapiro instead. 73190792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 73290792Sgshapiro builtin mailer pathnames. Use TCP instead. 73390792Sgshapiro PH map code updated to use the new libphclient API instead of the 73490792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 73590792Sgshapiro University of Illinois at Urbana-Champaign. 73690792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 73790792Sgshapiro for direct (command line) submissions. 73890792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 73990792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 74090792Sgshapiro Hagino of the KAME Project. 74190792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 74290792Sgshapiro whose content is rewritten similar to Reply-To:. 74390792Sgshapiro Proposed by Andrzej Filip. 74490792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 74590792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 74690792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 74790792Sgshapiro AUTH/STARTTLS related logfile entries. 74890792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 74990792Sgshapiro before logging. 75090792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 75190792Sgshapiro (at LogLevel 9/10 or higher). 75290792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 75390792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 75490792Sgshapiro in which most commands are rejected due to check_relay or 75590792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 75690792Sgshapiro Change logging format for cloned envelopes to be similar to that for 75790792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 75890792Sgshapiro of the Universitat Regensburg. 75990792Sgshapiro Added libsm, a C library of general purpose abstractions including 76090792Sgshapiro assertions, tracing and debugging with named debug categories, 76190792Sgshapiro exception handling, malloc debugging, resource pools, 76290792Sgshapiro portability abstractions, and an extensible buffered I/O 76390792Sgshapiro package. It will at some point replace libsmutil. 76490792Sgshapiro See libsm/index.html for details. 76590792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 76690792Sgshapiro care of by fork() and exit(). 76790792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 76890792Sgshapiro more consistent portablity amongst different platforms 76990792Sgshapiro new and old (from new libsm). 77090792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 77190792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 77290792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 77390792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 77490792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 77590792Sgshapiro synchronizations calls. 77690792Sgshapiro Add per-recipient status information to mailq -v output. 77790792Sgshapiro T_ANY queries are no longer used by sendmail. 77890792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 77990792Sgshapiro too (see include/sm/cdefs.h for more info). 78090792Sgshapiro sendmail -d now has general support for named debug categories. 78190792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 78290792Sgshapiro for details. 78390792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 78490792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 78590792Sgshapiro generated by this condition were illegal (not RFC conform). 78690792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 78790792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 78890792Sgshapiro mailer and the recipient has hence been rejected during the 78990792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 79090792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 79190792Sgshapiro that do not have postmaster defined. If an email was sent 79290792Sgshapiro from an address to which a DSN cannot be returned and 79390792Sgshapiro in which at least one recipient address is non-deliverable, 79490792Sgshapiro then that email had been delivered in each queue run. 79590792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 79690792Sgshapiro degli Studi dell'Insubria. 79790792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 79890792Sgshapiro i.e., the corresponding code is always compiled in now. 79990792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 80090792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 80190792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 80290792Sgshapiro attempting to canonify a hostname, some broken nameservers 80390792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 80490792Sgshapiro lookups. If you want to excuse this behavior, use this new 80590792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 80690792Sgshapiro Mark Roth of the University of Illinois at 80790792Sgshapiro Urbana-Champaign. 80890792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 80990792Sgshapiro noted by Joy Latten of IBM. 81090792Sgshapiro ConnectionRateThrottle limits the number of connections per second 81190792Sgshapiro to each daemon individually, not the overall number of 81290792Sgshapiro connections. 81390792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 81490792Sgshapiro sendmail to use a default alias schema as outlined in the 81590792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 81690792Sgshapiro cf/README. 81790792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 81890792Sgshapiro the first character after the class name is not a '/' or a 81990792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 82090792Sgshapiro rest of the line will be parsed as a map lookup. This 82190792Sgshapiro allows classes to be filled via a map lookup. See op.me 82290792Sgshapiro for more syntax information. Specifically, this can be 82390792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 82490792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 82590792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 82690792Sgshapiro example). 82790792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 82890792Sgshapiro the default schema used in the above two items. 82990792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 83090792Sgshapiro warning if a program being run from a mailer or file class 83190792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 83290792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 83390792Sgshapiro if a program being run from a mailer or file class 83490792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 83590792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 83690792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 83790792Sgshapiro (without quotes) will disable this and return to the 83890792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 83990792Sgshapiro Suggested by Bryan Stansell of GNAC. 84090792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 84190792Sgshapiro HELO/EHLO commands. 84290792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 84390792Sgshapiro possible protocol family which may be used for outgoing 84490792Sgshapiro connections. Restrictions placed on one family only affect 84590792Sgshapiro outgoing connections on that particular family. Because of 84690792Sgshapiro this change, the ${client_flags} macro is not set until the 84790792Sgshapiro connection is established. Based on patch from Motonori 84890792Sgshapiro Nakamura of Kyoto University. 84990792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 85090792Sgshapiro when the -bv option is given by users who are neither root 85190792Sgshapiro nor the TrustedUser so users can not read private aliases, 85290792Sgshapiro forwards, or :include: files. It also will override the -v 85390792Sgshapiro (verbose) command line option. 85490792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 85590792Sgshapiro address can't be used for the outgoing connection, fall 85690792Sgshapiro back to the settings in ClientPortOptions (if set). 85790792Sgshapiro Problem noted by John Beck of Sun Microsystems. 85890792Sgshapiro New named config file rule check_data for DATA command (input: 85990792Sgshapiro number of recipients). Based on patch from Mark Roth of 86090792Sgshapiro the University of Illinois at Urbana-Champaign. 86190792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 86290792Sgshapiro can be specified using the '#' option character. For 86390792Sgshapiro example, 'ETRN #queuegroup'. 86490792Sgshapiro If an LDAP server times out or becomes unavailable, close the 86590792Sgshapiro current connection and reopen to get to one of the fallback 86690792Sgshapiro servers. Patch from Paul Hilchey of the University of 86790792Sgshapiro British Columbia. 86890792Sgshapiro Make default error number on $#error messages 550 instead of 501 86990792Sgshapiro because 501 is not allowed on all commands. 87090792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 87190792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 87290792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 87390792Sgshapiro if required. 87490792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 87590792Sgshapiro class instead. 87690792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 87790792Sgshapiro "IPv6:" tag to identify the address properly. For example, 87890792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 87990792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 88090792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 88190792Sgshapiro MTA is running. For example, during a queue run. 88290792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 88390792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 88490792Sgshapiro Nelson of IBM. 88590792Sgshapiro The maximum number of commands before the MTA slows down when too 88690792Sgshapiro many "light weight" commands have been received are now 88790792Sgshapiro configurable during compile time. The current values and 88890792Sgshapiro their defaults are: 88990792Sgshapiro MAXBADCOMMANDS 25 unknown commands 89090792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 89190792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 89290792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 89390792Sgshapiro MAXETRNCOMMANDS 8 ETRN 89490792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 89590792Sgshapiro Costales of SL3D, Inc. 89690792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 89790792Sgshapiro ${MyMacro} is defined but also that it is not empty. 89890792Sgshapiro Properly quote usernames with special characters if they are used 89990792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 90090792Sgshapiro Meteorological Institute. 90190792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 90290792Sgshapiro messages for messages for mailing list expanded addresses 90390792Sgshapiro which are not delivered on the initial attempt. 90490792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 90590792Sgshapiro the final dot has been sent to avoid affecting future 90690792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 90790792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 90890792Sgshapiro file systems that require to call fsync() for a directory 90990792Sgshapiro if the meta-data in it has been changed. This should be 91090792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 91190792Sgshapiro See sendmail/README for further information. 91290792Sgshapiro Avoid file locking deadlock when updating the statistics file if 91390792Sgshapiro sendmail is signaled to terminate. Problem noted by 91490792Sgshapiro Christophe Wolfhugel of France Telecom. 91590792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 91690792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 91790792Sgshapiro the Finnish Meteorological Institute. 91890792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 91990792Sgshapiro from Peter A. Friend of EarthLink. 92090792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 92190792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 92290792Sgshapiro flora.ca. 92390792Sgshapiro Portability: 92490792Sgshapiro Remove support for AIX 2, which supports only 14 character 92590792Sgshapiro filenames and is outdated anyway. Suggested by 92690792Sgshapiro Valdis Kletnieks of Virginia Tech. 92790792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 92890792Sgshapiro i.e., use default /usr/sbin, change owner/group 92990792Sgshapiro of man pages and user-executable to root/sys, set 93090792Sgshapiro optimization limit to 0 (unlimited). Based on patch 93190792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 93290792Sgshapiro Hurtta of the Finnish Meteorological Institute. 93390792Sgshapiro Do not assume LDAP support is installed by default under 93490792Sgshapiro Solaris 8 and later. 93590792Sgshapiro Add support for OpenUNIX. 93690792Sgshapiro CONFIG: Increment version number of config file to 10. 93790792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 93890792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 93990792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 94090792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 94190792Sgshapiro temporary lookup failures. 94290792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 94390792Sgshapiro action to be taken by aborting the search for domain names 94490792Sgshapiro or IP nets. 94590792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 94690792Sgshapiro relay address as long as the other part allows the email 94790792Sgshapiro to get through. 94890792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 94990792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 95090792Sgshapiro entry like user+*@domain. This allows handling of details by 95190792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 95290792Sgshapiro introduced to match only non-empty details of addresses. 95390792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 95490792Sgshapiro and hence there is no required order within the MAILER 95590792Sgshapiro section anymore except for MAILER(`uucp') which must come 95690792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 95790792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 95890792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 95990792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 96090792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 96190792Sgshapiro in the access map which returns OK or RELAY actually 96290792Sgshapiro terminates check_* ruleset checking. 96390792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 96490792Sgshapiro tls_rcpt, see cf/README for details. 96590792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 96690792Sgshapiro STARTTLS has been used to "(version=${tls_version} 96790792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 96890792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 96990792Sgshapiro options friends/haters instead of "To:" and enable 97090792Sgshapiro specification of whole domains instead of just users. 97190792Sgshapiro Notice: this change is not backward compatible. 97290792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 97390792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 97490792Sgshapiro cf/README for details. 97590792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 97690792Sgshapiro the access map. Proposed by Randall Winchester of the 97790792Sgshapiro University of Maryland. 97890792Sgshapiro CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for 97990792Sgshapiro the local mailer. Proposed by Ingo Brueckl of Wupper Online. 98090792Sgshapiro CONFIG: confRELAY_MSG/confREJECT_MSG can override the default 98190792Sgshapiro messages for an unauthorized relaying attempt/for access 98290792Sgshapiro map entries with RHS REJECT, respectively. 98390792Sgshapiro CONFIG: FEATURE(`always_add_domain') takes an optional argument 98490792Sgshapiro to specify another domain to be added instead of the local one. 98590792Sgshapiro Suggested by Richard H. Gumpertz of Computer Problem 98690792Sgshapiro Solving. 98790792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 98890792Sgshapiro options, see doc/op/op.me for details. 98990792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 99090792Sgshapiro the security layer in SMTP AUTH (SASL). 99190792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 99290792Sgshapiro immediately. 99390792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 99490792Sgshapiro allows checking of the return values of the DNS lookups. 99590792Sgshapiro See cf/README for details. 99690792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 99790792Sgshapiro temporary lookup failures. 99890792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 99990792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 100090792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 100190792Sgshapiro memory use. 100290792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 100390792Sgshapiro of the sender and the recipient address delimited by the 100490792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 100590792Sgshapiro in the access map. Based on code contributed by Mathias 100690792Sgshapiro Koerber of Singapore Telecommunications Ltd. 100790792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 100890792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 100990792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 101090792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 101190792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 101290792Sgshapiro the recipient host if LUSER_RELAY is used. 101390792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 101490792Sgshapiro +detail portion of the address when passing address to 101590792Sgshapiro local delivery agent. Disables alias and .forward +detail 101690792Sgshapiro stripping.

Equivalent hostnames are replaced by the 102190792Sgshapiro masquerade domain name for lookups. See cf/README for 102290792Sgshapiro additional details. 102390792Sgshapiro CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which 102490792Sgshapiro instructs the rulesets on what to do if the address being 102590792Sgshapiro looked up has +detail information. See cf/README for more 102690792Sgshapiro information. 102790792Sgshapiro CONFIG: When chosing a new destination via LDAP Routing, also look 102890792Sgshapiro up the new routing address/host in the mailertable. Based 102990792Sgshapiro on patch from Don Badrak of the United States Census Bureau. 103090792Sgshapiro CONFIG: Do not reject the SMTP Mail from: command if LDAP Routing 103190792Sgshapiro is in use and the bounce option is enabled. Only reject 103290792Sgshapiro recipients as user unknown. 103390792Sgshapiro CONFIG: Provide LDAP support for the remaining database map 103490792Sgshapiro features. See the ``USING LDAP FOR ALIASES AND MAPS'' 103590792Sgshapiro section of cf/README for more information. 103690792Sgshapiro CONFIG: Add confLDAP_CLUSTER which defines the ${sendmailMTACluster} 103790792Sgshapiro macro used for LDAP searches as described above in ``USING 103890792Sgshapiro LDAP FOR ALIASES, MAPS, AND CLASSES''. 103990792Sgshapiro CONFIG: confCLIENT_OPTIONS has been replaced by CLIENT_OPTIONS(), 104090792Sgshapiro which takes the options as argument and can be used 104190792Sgshapiro multiple times; see cf/README for details. 104290792Sgshapiro CONFIG: Add configuration macros for new options: 104390792Sgshapiro confBAD_RCPT_THROTTLE BadRcptThrottle 104490792Sgshapiro confDIRECT_SUBMISSION_MODIFIERS DirectSubmissionModifiers 104590792Sgshapiro confMAILBOX_DATABASE MailboxDatabase 104690792Sgshapiro confMAX_QUEUE_CHILDREN MaxQueueChildren 104790792Sgshapiro confMAX_RUNNERS_PER_QUEUE MaxRunnersPerQueue 104890792Sgshapiro confNICE_QUEUE_RUN NiceQueueRun 104990792Sgshapiro confQUEUE_FILE_MODE QueueFileMode 105090792Sgshapiro confFAST_SPLIT FastSplit 105190792Sgshapiro confTLS_SRV_OPTIONS TLSSrvOptions 105290792Sgshapiro See above (and related documentation) for further information. 105390792Sgshapiro CONFIG: Add configuration variables for new timeout options: 105490792Sgshapiro confTO_ACONNECT Timeout.aconnect 105590792Sgshapiro confTO_AUTH Timeout.auth 105690792Sgshapiro confTO_LHLO Timeout.lhlo 105790792Sgshapiro confTO_STARTTLS Timeout.starttls 105890792Sgshapiro CONFIG: Add configuration macros for mail filter API: 105990792Sgshapiro confINPUT_MAIL_FILTERS InputMailFilters 106090792Sgshapiro confMILTER_LOG_LEVEL Milter.LogLevel 106190792Sgshapiro confMILTER_MACROS_CONNECT Milter.macros.connect 106290792Sgshapiro confMILTER_MACROS_HELO Milter.macros.helo 106390792Sgshapiro confMILTER_MACROS_ENVFROM Milter.macros.envfrom 106490792Sgshapiro confMILTER_MACROS_ENVRCPT Milter.macros.envrcpt 106590792Sgshapiro Mail filters can be defined via INPUT_MAIL_FILTER() and 106690792Sgshapiro MAIL_FILTER(). See libmilter/README, cf/README, and 106790792Sgshapiro doc/op/op.me for details. 106890792Sgshapiro CONFIG: Add support for accepting temporarily unresolvable domains. 106990792Sgshapiro See cf/README for details. Based on patch by Motonori 107090792Sgshapiro Nakamura of Kyoto University. 107190792Sgshapiro CONFIG: confDEQUOTE_OPTS can be used to specify options for the 107290792Sgshapiro dequote map. 107390792Sgshapiro CONFIG: New macro QUEUE_GROUP() to define queue groups. 107490792Sgshapiro CONFIG: New FEATURE(`queuegroup') to select a queue group based 107590792Sgshapiro on the full e-mail address or the domain of the recipient. 107690792Sgshapiro CONFIG: Any IPv6 addresses used in configuration should be prefixed 107790792Sgshapiro by the "IPv6:" tag to identify the address properly. For 107890792Sgshapiro example, if you want to use the IPv6 address 107990792Sgshapiro 2002:c0a8:51d2::23f4 in the access database, you would need 108090792Sgshapiro to use IPv6:2002:c0a8:51d2::23f4 on the left hand side. 108190792Sgshapiro This affects the access database as well as the 108290792Sgshapiro relay-domains and local-host-names files. 108390792Sgshapiro CONFIG: OSTYPE(aux) has been renamed to OSTYPE(a-ux). 108490792Sgshapiro CONFIG: Avoid expansion of m4 keywords in SMART_HOST. 108590792Sgshapiro CONFIG: Add MASQUERADE_EXCEPTION_FILE() for reading masquerading 108690792Sgshapiro exceptions from a file.

New option -D mbdb specifies the 110290792Sgshapiro mailbox database type. 110390792Sgshapiro MAIL.LOCAL: New option "-h filename" which instructs mail.local to 110490792Sgshapiro deliver the mail to the named file in the user's home 110590792Sgshapiro directory instead of the system mail spool area. Based on 110690792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 110790792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 110890792Sgshapiro doesn't truncate the statistics file. 110990792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 111090792Sgshapiro instead of white space. 111190792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 111290792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 111390792Sgshapiro Meteorological Institute. 111490792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 111590792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 111690792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 111790792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 111890792Sgshapiro instead of syslog. 111990792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 112090792Sgshapiro in the password file. The -f and -m options must be used 112190792Sgshapiro to specify the database and message file since there is no 112290792Sgshapiro home directory for the default settings for these options. 112390792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 112490792Sgshapiro local mail recipients; it reads the MailboxDatabase option 112590792Sgshapiro from the sendmail.cf file. New option -C cffile which 112690792Sgshapiro specifies the path of the sendmail.cf file. 112790792Sgshapiro New Directories: 112890792Sgshapiro libmilter/docs 112990792Sgshapiro New Files: 113090792Sgshapiro cf/cf/README 113190792Sgshapiro cf/cf/submit.cf 113290792Sgshapiro cf/cf/submit.mc 113390792Sgshapiro cf/feature/authinfo.m4 113490792Sgshapiro cf/feature/compat_check.m4 113590792Sgshapiro cf/feature/enhdnsbl.m4 113690792Sgshapiro cf/feature/msp.m4 113790792Sgshapiro cf/feature/local_no_masquerade.m4 113890792Sgshapiro cf/feature/lookupdotdomain.m4 113990792Sgshapiro cf/feature/preserve_luser_host.m4 114090792Sgshapiro cf/feature/preserve_local_plus_detail.m4 114190792Sgshapiro cf/feature/queuegroup.m4 114290792Sgshapiro cf/sendmail.schema 114390792Sgshapiro contrib/dnsblaccess.m4 114490792Sgshapiro devtools/M4/UNIX/sm-test.m4 114590792Sgshapiro devtools/OS/OpenUNIX.5.i386 114690792Sgshapiro editmap/* 114790792Sgshapiro include/sm/* 114890792Sgshapiro libsm/* 114990792Sgshapiro libsmutil/cf.c 115090792Sgshapiro libsmutil/err.c 115190792Sgshapiro sendmail/SECURITY 115290792Sgshapiro sendmail/TUNING 115390792Sgshapiro sendmail/bf.c 115490792Sgshapiro sendmail/bf.h 115590792Sgshapiro sendmail/sasl.c 115690792Sgshapiro sendmail/sm_resolve.c 115790792Sgshapiro sendmail/sm_resolve.h 115890792Sgshapiro sendmail/tls.c 115990792Sgshapiro Deleted Files: 116090792Sgshapiro cf/feature/rbl.m4 116190792Sgshapiro cf/ostype/aix2.m4 116290792Sgshapiro devtools/OS/AIX.2 116390792Sgshapiro include/sendmail/cdefs.h 116490792Sgshapiro include/sendmail/errstring.h 116590792Sgshapiro include/sendmail/useful.h 116690792Sgshapiro libsmutil/errstring.c 116790792Sgshapiro sendmail/bf_portable.c 116890792Sgshapiro sendmail/bf_portable.h 116990792Sgshapiro sendmail/bf_torek.c 117090792Sgshapiro sendmail/bf_torek.h 117190792Sgshapiro sendmail/clock.c 117290792Sgshapiro Renamed Files: 117390792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 117490792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 117590792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 117690792Sgshapiro 117782017Sgshapiro8.11.6/8.11.6 2001/08/20 117882017Sgshapiro SECURITY: Fix a possible memory access violation when specifying 117982017Sgshapiro out-of-bounds debug parameters.

From 156266494Sgshapiro Tom Moore of NCR. 156366494Sgshapiro NeXT 3.X and 4.X installs man pages in /usr/man. From 156466494Sgshapiro Hisanori Gogota of NTT/InterCommunicationCenter. 156566494Sgshapiro Solaris 8 and later include /var/run. The default PID file 156666494Sgshapiro location is now /var/run/sendmail.pid. From John 156766494Sgshapiro Beck of Sun Microsystems. 156866494Sgshapiro SFIO includes snprintf() for those operating systems 156966494Sgshapiro which do not. From Todd C. Miller of Courtesan 157066494Sgshapiro Consulting. 157166494Sgshapiro CONFIG: Use the result of _CERT_REGEX_SUBJECT_ not {cert_subject}. 157266494Sgshapiro Problem noted by Kaspar Brand of futureLab AG. 157366494Sgshapiro CONFIG: Change 553 SMTP reply code to 501 to avoid problems with 157466494Sgshapiro errors in the MAIL address. 157566494Sgshapiro CONFIG: Fix FEATURE(nouucp) usage in example .mc files. Problem 157666494Sgshapiro noted by Ron Jarrell of Virginia Tech. 157766494Sgshapiro CONFIG: Add support for Solaris 8 (and later) as OSTYPE(solaris8). 157866494Sgshapiro Contributed by John Beck of Sun Microsystems. 157966494Sgshapiro CONFIG: Set confFROM_HEADER such that the mail hub can possibly add 158066494Sgshapiro GECOS information for an address. This more closely 158166494Sgshapiro matches pre-8.10 nullclient behavior. From Per Hedeland of 158266494Sgshapiro Ericsson. 158366494Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 158466494Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 158566494Sgshapiro mailer as described in cf/README. 158666494Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 158766494Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 158866494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 158966494Sgshapiro makemap to 'unmake' the map. 159066494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 159166494Sgshapiro sendmail. 159266494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 159366494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 159466494Sgshapiro Meteorological Institute. 159566494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 159666494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 159766494Sgshapiro dot as the only character on the line. 159866494Sgshapiro New Files: 159966494Sgshapiro cf/ostype/solaris8.m4 160066494Sgshapiro 160164562Sgshapiro8.11.0/8.11.0 2000/07/19 160264562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 160364562Sgshapiro (not the normal case), some operating systems will still 160464562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 160564562Sgshapiro to drop all of its privileges. If sendmail needs to drop 160664562Sgshapiro these privileges and the operating system doesn't set the 160764562Sgshapiro saved-uid as well, exit with an error. Problem noted by 160864562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 160964562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 161064562Sgshapiro it populates. It is possible that some broken 161164562Sgshapiro implementations of snprintf() exist that do not do this. 161264562Sgshapiro Systems in this category should compile with 161364562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 161464562Sgshapiro system and report broken implementations to 161564562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 161664562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 161764562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 161864562Sgshapiro Implementation influenced by the example programs of 161964562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 162064562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 162164562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 162264562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 162364562Sgshapiro cf/README and doc/op/op.*. 162464562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 162564562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 162664562Sgshapiro ${server_name}, and ${server_addr}. These are documented 162764562Sgshapiro in cf/README and doc/op/op.*. 162864562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 162964562Sgshapiro random data. 163064562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 163164562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 163264562Sgshapiro try to use STARTTLS despite the security problems. 163364562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 163464562Sgshapiro support encryption. Based on code contributed by Tim 163564562Sgshapiro Martin of CMU. 163664562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 163764562Sgshapiro strength factor. 163864562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 163964562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 164064562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 164164562Sgshapiro of CMU. 164264562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 164364562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 164464562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 164564562Sgshapiro Fix the default family selection for DaemonPortOptions. As 164664562Sgshapiro documented, unless a family is specified in a 164764562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 164864562Sgshapiro also the default if no DaemonPortOptions value is set. 164964562Sgshapiro Therefore, IPv6 users should configure additional sockets 165064562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 165164562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 165264562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 165364562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 165464562Sgshapiro the interface information for an outgoing connection. 165564562Sgshapiro Not doing so was creating a mismatch between the socket 165664562Sgshapiro family and address used in subsequent connections if the 165764562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 165864562Sgshapiro by John Beck of Sun Microsystems. 165964562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 166064562Sgshapiro family based on the IP address. ${if_family} is no longer 166164562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 166264562Sgshapiro of Sun Microsystems. 166364562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 166464562Sgshapiro macros for both the incoming interface address/family and 166564562Sgshapiro the outgoing interface address/family. In order for M=b 166664562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 166764562Sgshapiro the incoming information in the queue file for later 166864562Sgshapiro delivery attempts. 166964562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 167064562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 167164562Sgshapiro smoe.org. 167264562Sgshapiro Add more vigilance in checking for putc() errors on output streams 167364562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 167464562Sgshapiro noted by Graeme Hewson of Oracle. 167564562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 167664562Sgshapiro Problem noted by Ajay Matia. 167764562Sgshapiro Under certain circumstances, an address could be listed as deferred 167864562Sgshapiro but would be bounced back to the sender as failed to be 167964562Sgshapiro delivered when it really should have been queued. Problem 168064562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 168164562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 168264562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 168364562Sgshapiro Hedeland of Ericsson. 168464562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 168564562Sgshapiro is defined to avoid a core dump due to incompatibilities 168664562Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 168764562Sgshapiro of Northern Illinois University. 168864562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 168964562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 169064562Sgshapiro Convert the free disk space shown in a control socket status query 169164562Sgshapiro to kilobyte units. 169264562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 169364562Sgshapiro looking up the hostname, requeue the message for a later 169464562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 169564562Sgshapiro Polytechnic. 169664562Sgshapiro Under the proper circumstances, failed connections would be recorded 169764562Sgshapiro as "Bad file number" instead of "Connection failed" in the 169864562Sgshapiro queue file and persistent host status. Problem noted by 169964562Sgshapiro Graeme Hewson of Oracle. 170064562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 170164562Sgshapiro within the hoststatus directory (e.g., lost+found). 170264562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 170364562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 170464562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 170564562Sgshapiro If a message data file can't be opened at delivery time, panic and 170664562Sgshapiro abort the attempt instead of delivering a message that 170764562Sgshapiro states "<<< No Message Collected >>>". 170864562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 170964562Sgshapiro restrictive. Problem noted by Mark G. Thomas of Mark 171064562Sgshapiro G. Thomas Consulting. 171164562Sgshapiro Preserve source port number instead of replacing it with the ident 171264562Sgshapiro port number (113). 171364562Sgshapiro Document the queue status characters in the mailq man page. 171464562Sgshapiro Suggested by Ulrich Windl of the Universitat Regensburg. 171564562Sgshapiro Process queued items in which none of the recipient addresses have 171664562Sgshapiro host portions (or there are no recipients). Problem noted 171764562Sgshapiro by Valdis Kletnieks of Virginia Tech. 171864562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 171964562Sgshapiro only the first to open the connection is allowed to close 172064562Sgshapiro it so a later map close doesn't break the connection for 172164562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 172264562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 172364562Sgshapiro authentication. Patch from Rainer Schoepf of the 172464562Sgshapiro University of Mainz. 172564562Sgshapiro Provide workaround for inconsistent handling of data passed 172664562Sgshapiro via callbacks to Cyrus SASL prior to version 1.5.23. 172764562Sgshapiro Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.

From Jun 173264562Sgshapiro Kuriyama of IMG SRC, Inc. and the FreeBSD Project. 173364562Sgshapiro Replace code for finding the number of CPUs on HPUX. 173464562Sgshapiro NCRUNIX MP-RAS 3.02 SO_REUSEADDR socket option does not 173564562Sgshapiro work properly causing problems if the accept() 173664562Sgshapiro fails and the socket needs to be reopened. Patch 173764562Sgshapiro from Tom Moore of NCR. 173864562Sgshapiro NetBSD uses a .0 extension of formatted man pages. From 173966494Sgshapiro Andrew Brown of Crossbar Security. 174064562Sgshapiro Return to using the IPv6 AI_DEFAULT flag instead of AI_V4MAPPED 174164562Sgshapiro for calls to getipnodebyname(). The Linux 174264562Sgshapiro implementation is broken so AI_ADDRCONFIG is stripped 174364562Sgshapiro under Linux.

From Todd C. Miller of 189664562Sgshapiro Courtesan Consulting. 189764562Sgshapiro SINIX doesn't have random(3). From Gerald Rinske of 189864562Sgshapiro Siemens Business Services. 189964562Sgshapiro CONFIG: Change error message about unresolvable sender domain to 190064562Sgshapiro include the sender address. Proposed by Wolfgang Rupprecht 190164562Sgshapiro of WSRCC. 190264562Sgshapiro CONFIG: Fix usenet mailer calls. 190364562Sgshapiro CONFIG: If RELAY_MAILER_FLAGS is not defined, use SMTP_MAILER_FLAGS 190464562Sgshapiro to be backward compatible with 8.9. 190564562Sgshapiro CONFIG: Change handling of default case @domain for virtusertable 190664562Sgshapiro to allow for +*@domain to deal with +detail. 190764562Sgshapiro CONTRIB: Remove converting.sun.configs -- it is obsolete. 190864562Sgshapiro DEVTOOLS: confUBINMODE was being ignored. Fix from KITAZIMA, Tuneki 190964562Sgshapiro of NEC. 191064562Sgshapiro DEVTOOLS: Add to NCR platform list and include the architecture 191164562Sgshapiro (i486). From Tom J. Moore of NCR. 191264562Sgshapiro DEVTOOLS: SECURITY: Change method of linking with sendmail utility 191364562Sgshapiro libraries to work around the AIX 4.X and SunOS 4.X linker's 191464562Sgshapiro overloaded -L option. Problem noted by Valdis Kletnieks of 191564562Sgshapiro Virginia Tech. 191664562Sgshapiro DEVTOOLS: configure.sh was overriding the user's choice for 191764562Sgshapiro confNROFF. Problem noted by Glenn A. Malling of Syracuse 191864562Sgshapiro University. 191964562Sgshapiro DEVTOOLS: New variables conf_prog_LIB_POST and confBLDVARIANT added 192064562Sgshapiro for other internal projects but included in the open source 192164562Sgshapiro release. 192264562Sgshapiro LIBSMDB: Check for ".db" instead of simply "db" at the end of the 192364562Sgshapiro map name to determine whether or not to add the extension. 192464562Sgshapiro This fixes makemap when building the userdb file. Problem 192564562Sgshapiro noted by Andrew J Cole of the University of Leeds. 192664562Sgshapiro LIBSMDB: Allow a database to be opened for updating and created if 192764562Sgshapiro it doesn't already exist. Problem noted by Rand Wacker of 192864562Sgshapiro Sendmail. 192964562Sgshapiro LIBSMDB: If type is SMDB_TYPE_DEFAULT and both NEWDB and NDBM are 193064562Sgshapiro available, fall back to NDBM if NEWDB open fails. This 193164562Sgshapiro fixes praliases. Patch from John Beck of Sun Microsystems. 193264562Sgshapiro LIBSMUTIL: safefile()'s SFF_NOTEXCL check was being misinterpreted 193364562Sgshapiro as SFF_NOWRFILES. 193464562Sgshapiro OP.ME: Clarify some issues regarding mailer flags. Suggested by 193564562Sgshapiro Martin Mokrejs of The Charles University and Neil Rickert of 193664562Sgshapiro Northern Illinois University. 193764562Sgshapiro PRALIASES: Restore 8.9.X functionality of being able to search for 193864562Sgshapiro particular keys in a database by specifying the keys on the 193964562Sgshapiro command line. Man page updated accordingly. Patch from 194064562Sgshapiro John Beck of Sun Microsystems. 194164562Sgshapiro VACATION: SunOS 4.X portability from Charles Levert of Ecole 194264562Sgshapiro Polytechnique de Montreal. 194364562Sgshapiro VACATION: Fix -t option which is ignored but available for 194464562Sgshapiro compatibility with Sun's version, based on patch from 194564562Sgshapiro Volker Dobler of Infratest Burke. 194664562Sgshapiro Added Files: 194764562Sgshapiro devtools/M4/UNIX/smlib.m4 194864562Sgshapiro devtools/OS/OSF1.V5.0 194964562Sgshapiro Deleted Files: 195064562Sgshapiro contrib/converting.sun.configs 195164562Sgshapiro Deleted Directories (already done in 8.10.0 but not listed): 195264562Sgshapiro doc/intro 195364562Sgshapiro doc/usenix 195464562Sgshapiro doc/changes 195564562Sgshapiro 195664562Sgshapiro8.10.0/8.10.0 2000/03/01 195764562Sgshapiro ************************************************************* 195880785Sgshapiro * The engineering department at Sendmail, Inc. has suffered * 195980785Sgshapiro * the tragic loss of a key member of our engineering team. * 196080785Sgshapiro * Julie Van Bourg was the Vice President of Engineering * 196180785Sgshapiro * at Sendmail, Inc. during the development and deployment * 196280785Sgshapiro * of this release.

Problem noted by Michal Zalewski of the 197764562Sgshapiro "Internet for Schools" project (IdS). 197864562Sgshapiro SECURITY: There is a potential for a denial of service attack if 197964562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 198064562Sgshapiro sendmail process while it is rebuilding the aliases file 198164562Sgshapiro (leaving it in an inconsistent state). This option and 198264562Sgshapiro its use is deprecated and will be removed from a future 198364562Sgshapiro version of sendmail. 198464562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 198564562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 198664562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 198764562Sgshapiro (IdS). 198864562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 198964562Sgshapiro a large number of files. See cf/README for more details. 199064562Sgshapiro The directory structure of the distribution has changed slightly 199164562Sgshapiro for easier code sharing among the programs. 199264562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 199364562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 199464562Sgshapiro which hold the client's authentication credentials, 199564562Sgshapiro the mechanism used for authentication, and the 199664562Sgshapiro authorization identity (i.e., the AUTH= parameter if 199764562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 199864562Sgshapiro On systems which use the Torek stdio library (all of the BSD 199964562Sgshapiro distributions), use memory-buffered files to reduce 200064562Sgshapiro file system overhead by not creating temporary files on 200164562Sgshapiro disk. Contributed by Exactis.com, Inc. 200264562Sgshapiro New option DataFileBufferSize to control the maximum size of a 200364562Sgshapiro memory-buffered data (df) file before a disk-based file is 200464562Sgshapiro used. Contributed by Exactis.com, Inc. 200564562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 200664562Sgshapiro memory-buffered transcript (xf) file before a disk-based 200764562Sgshapiro file is used. Contributed by Exactis.com, Inc. 200864562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 200964562Sgshapiro now listen on several different ports. Use: 201064562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 201164562Sgshapiro to run a Message Submission Agent (MSA); this is turned 201264562Sgshapiro on by default in m4-generated .cf files; it can be turned 201364562Sgshapiro off with FEATURE(`no_default_msa'). 201464562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 201564562Sgshapiro begin using RFC 2476 Message Submission for initial user 201664562Sgshapiro message submission. XUSR may disappear from a future release. 201764562Sgshapiro The new '-G' (relay (gateway) submission) command line option 201864562Sgshapiro indicates that the message being submitted from the command 201964562Sgshapiro line is for relaying, not initial submission. This means 202064562Sgshapiro the message will be rejected if the addresses are not fully 202164562Sgshapiro qualified and no canonicalization will be done. Future 202264562Sgshapiro releases may even reject improperly formed messages. 202364562Sgshapiro The '-U' (initial user submission) command line option is 202464562Sgshapiro deprecated and may be removed from a future release. 202564562Sgshapiro Mail user agents should begin using '-G' to indicate that 202664562Sgshapiro this is a relay submission (the inverse of -U). 202764562Sgshapiro The next release of sendmail will assume that any message submitted 202864562Sgshapiro from the command line is an initial user submission and act 202964562Sgshapiro accordingly. 203064562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 203164562Sgshapiro program or deliver to file as the owner of that file, the 203264562Sgshapiro address is marked as unsafe. This means if RunAsUser is 203364562Sgshapiro set, users won't be able to use programs or delivery to 203464562Sgshapiro files in their .forward files. Administrators can override 203564562Sgshapiro this by setting the DontBlameSendmail option to the new 203664562Sgshapiro setting NonRootSafeAddr. 203764562Sgshapiro Allow group or world writable directories if the sticky bit is set 203864562Sgshapiro on the directory and DontBlameSendmail is set to 203964562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 204064562Sgshapiro InCert Software. 204164562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 204264562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 204364562Sgshapiro set in the DontBlameSendmail option. Requested by many. 204464562Sgshapiro New Timeout.control option to limit the total time spent satisfying 204564562Sgshapiro a control socket request. 204664562Sgshapiro New Timeout.resolver options for controlling BIND resolver 204764562Sgshapiro settings: 204864562Sgshapiro Timeout.resolver.retrans 204964562Sgshapiro Sets the resolver's retransmission time interval (in 205064562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 205164562Sgshapiro and Timeout.resolver.retrans.normal. 205264562Sgshapiro Timeout.resolver.retrans.first 205364562Sgshapiro Sets the resolver's retransmission time interval (in 205464562Sgshapiro seconds) for the first attempt to deliver a message. 205564562Sgshapiro Timeout.resolver.retrans.normal 205664562Sgshapiro Sets the resolver's retransmission time interval (in 205764562Sgshapiro seconds) for all resolver lookups except the first 205864562Sgshapiro delivery attempt. 205964562Sgshapiro Timeout.resolver.retry 206064562Sgshapiro Sets the number of times to retransmit a resolver 206164562Sgshapiro query. Sets both Timeout.resolver.retry.first 206264562Sgshapiro and Timeout.resolver.retry.normal. 206364562Sgshapiro Timeout.resolver.retry.first 206464562Sgshapiro Sets the number of times to retransmit a resolver 206564562Sgshapiro query for the first attempt to deliver a message. 206664562Sgshapiro Timeout.resolver.retry.normal 206764562Sgshapiro Sets the number of times to retransmit a resolver 206864562Sgshapiro query for all resolver lookups except the first 206964562Sgshapiro delivery attempt. 207064562Sgshapiro Contributed by Exactis.com, Inc. 207164562Sgshapiro Support multiple queue directories. To use multiple queues, supply 207264562Sgshapiro a QueueDirectory option value ending with an asterisk. For 207364562Sgshapiro example, /var/spool/mqueue/q* will use all of the 207464562Sgshapiro directories or symbolic links to directories beginning with 207564562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 207664562Sgshapiro mind, the queue directory structure should not be changed 207764562Sgshapiro while sendmail is running. Queue runs create a separate 207864562Sgshapiro process for running each queue unless the verbose flag is 207964562Sgshapiro given on a non-daemon queue run. New items are randomly 208064562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 208164562Sgshapiro Support different directories for qf, df, and xf queue files; if 208264562Sgshapiro subdirectories or symbolic links to directories of those names 208364562Sgshapiro exist in the queue directories, they are used for the 208464562Sgshapiro corresponding queue files. Keep in mind, the queue 208564562Sgshapiro directory structure should not be changed while sendmail is 208664562Sgshapiro running. Proposed by Mathias Koerber of Singapore 208764562Sgshapiro Telecommunications Ltd. 208864562Sgshapiro New queue file naming system which uses a filename guaranteed to be 208964562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 209064562Sgshapiro without fancy file system locking. Queued items can be 209164562Sgshapiro moved between queues easily. Contributed by Exactis.com, 209264562Sgshapiro Inc. 209364562Sgshapiro Messages which are undeliverable due to temporary address failures 209464562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 209564562Sgshapiro set. Contributed by Exactis.com, Inc. 209664562Sgshapiro New command line option '-L tag' which sets the identifier used for 209764562Sgshapiro syslog. Contributed by Exactis.com, Inc. 209864562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 209964562Sgshapiro avoids opening and reading each queue file when preparing 210064562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 210164562Sgshapiro Shared memory counters and microtimers functionality has been 210264562Sgshapiro donated by Exactis.com, Inc. 210364562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 210464562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 210564562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 210664562Sgshapiro being added. Suggested by Michael K. Sanders. 210764562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 210864562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 210964562Sgshapiro and John Beck of Sun Microsystems. 211064562Sgshapiro In low-disk space situations, where sendmail would previously refuse 211164562Sgshapiro connections, still accept them, but only allow ETRN commands. 211264562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 211364562Sgshapiro Ltd. 211464562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 211564562Sgshapiro on systems which support them. This can be used with LMTP 211664562Sgshapiro local delivery agents which listen on a named socket. An 211764562Sgshapiro example mailer might be: 211864562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 211964562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 212064562Sgshapiro A=FILE /var/run/lmtpd 212164562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 212264562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 212364562Sgshapiro instead. 212464562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 212564562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 212664562Sgshapiro connections), IPC (which will be deprecated in a future 212764562Sgshapiro version), and FILE (for UNIX domain socket delivery). 212864562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 212964562Sgshapiro flags. 213064562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 213164562Sgshapiro body of the original message on delivery status 213264562Sgshapiro notifications. 213364562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 213464562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 213564562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 213664562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 213764562Sgshapiro Steve Schweinhart of America Online. 213864562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 213964562Sgshapiro not be set after rulesets are defined. Suggested by 214064562Sgshapiro Mitchell Blank Jr of Exec-PC. 214164562Sgshapiro Do not report temporary failure on delivery to files. In 214264562Sgshapiro interactive delivery mode, this would result in two SMTP 214364562Sgshapiro responses after the DATA command. Problem noted by 214464562Sgshapiro Nik Conwell of Boston University. 214564562Sgshapiro Check file close when mailing to files.

Hillegas of Princeton University. 214964562Sgshapiro Always bind to the LDAP server regardless of whether you are using 215064562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 215164562Sgshapiro @Home Network. 215264562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 215364562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 215464562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 215564562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 215664562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 215764562Sgshapiro similar to check_rcpt etc. 215864562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 215964562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 216064562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 216164562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 216264562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 216364562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 216464562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 216564562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 216664562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 216764562Sgshapiro the corresponding DSN parameter values. Proposed by 216864562Sgshapiro Mathias Herberts. 216964562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 217064562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 217164562Sgshapiro before the message has been collected, thereafter it holds 217264562Sgshapiro the message size as computed by sendmail (and can be used 217364562Sgshapiro in check_compat). 217464562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 217564562Sgshapiro sendmail is using instead of the value of the DeliveryMode 217664562Sgshapiro option. 217764562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 217864562Sgshapiro Drop explicit From: if same as what would be generated only if it is 217964562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 218064562Sgshapiro Write pid to file also if sendmail only processes the queue. 218164562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 218264562Sgshapiro Log "low on disk space" only when necessary. 218364562Sgshapiro New macro ${load_avg} can be used to check the current load average. 218464562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 218564562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 218664562Sgshapiro is set. 218764562Sgshapiro Flag -S for maps to specify the character which is substituted 218864562Sgshapiro for spaces (instead of the default given by O BlankSub). 218964562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 219064562Sgshapiro This flag is set by default for the host map. Based on a 219164562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 219264562Sgshapiro Open maps only on demand, not at startup. 219364562Sgshapiro Log warning about unsupported IP address families. 219464562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 219564562Sgshapiro of the sum of all headers. This can be used to prevent 219664562Sgshapiro a denial-of-service attack. 219764562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 219864562Sgshapiro headers and parameters within those headers. This option 219964562Sgshapiro is intended to protect mail user agents from buffer 220064562Sgshapiro overflow attacks. 220164562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 220264562Sgshapiro alias recursion. 220364562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 220464562Sgshapiro Map type syslog to log the key via syslogd. 220564562Sgshapiro Entries in the alias file can be continued by putting a backslash 220664562Sgshapiro directly before the newline. 220764562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 220864562Sgshapiro dead.letter file, formerly hardcoded to 220964562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 221064562Sgshapiro default), sendmail will not attempt to save to a 221164562Sgshapiro system-wide dead.letter file if it can not bounce the mail 221264562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 221364562Sgshapiro file as it has in the past when the dead.letter file 221464562Sgshapiro could not be opened. 221564562Sgshapiro New option PidFile to define the location of the pid file. The 221664562Sgshapiro value of this option is macro expanded. 221764562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 221864562Sgshapiro process title shown in 'ps' listings. 221964562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 222064562Sgshapiro (along with the already existing macros): 222164562Sgshapiro ${daemon_info} Daemon information, e.g. 222264562Sgshapiro SMTP+queueing@00:30:00 222364562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 222464562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 222564562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 222664562Sgshapiro ${daemon_port} Daemon port, e.g., 25 222764562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 222864562Sgshapiro New macros especially for virtual hosting: 222964562Sgshapiro ${if_name} hostname of interface of incoming connection. 223064562Sgshapiro ${if_addr} address of interface of incoming connection. 223164562Sgshapiro The latter is only set if the interface does not belong to the 223264562Sgshapiro loopback net. 223364562Sgshapiro If a message being accepted via a method other than SMTP and 223464562Sgshapiro would be rejected by a header check, do not send the message. 223564562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 223664562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 223764562Sgshapiro Provide header value as quoted string in the macro 223864562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 223964562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 224064562Sgshapiro The length of the header value is stored in ${hdrlen}. 224164562Sgshapiro H*: allows to specify a default ruleset for header checks. This 224264562Sgshapiro ruleset will only be called if the individual header does 224364562Sgshapiro not have its own ruleset assigned. Suggested by Jan 224464562Sgshapiro Krueger of Unix-AG of University of Hannover. 224564562Sgshapiro The name of the header field stored in ${hdr_name}. 224664562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 224764562Sgshapiro removed if the config file version is greater than or equal 224864562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 224964562Sgshapiro input "token (1)" but does not match "token". 225064562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 225164562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 225264562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 225364562Sgshapiro Ericsson. 225464562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 225564562Sgshapiro messages with 8-bit text in headers. Problem noted by 225664562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 225764562Sgshapiro of Ericsson. 225864562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 225964562Sgshapiro modified database map file. Problem noted by Chris Adams 226064562Sgshapiro of Renaissance Internet Services. 226164562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 226264562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 226364562Sgshapiro queue up the message instead of bouncing it. 226464562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 226564562Sgshapiro standard does not provide any indication of what to do when 226664562Sgshapiro something other than 250 is received. Based on a patch 226764562Sgshapiro from Steve Schweinhart of America Online. 226864562Sgshapiro New option TrustedUser allows to specify a user who can own 226964562Sgshapiro important files instead of root. This requires HASFCHOWN. 227064562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 227164562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 227264562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 227364562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 227464562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 227564562Sgshapiro $? tests also whether the macro is non-null. 227664562Sgshapiro Print an error message if a mailer definition contains an invalid 227764562Sgshapiro equate name. 227864562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 227964562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 228064562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 228164562Sgshapiro mailer to return after sending all data to it. 228264562Sgshapiro Only free memory from the process list when adding a new process 228364562Sgshapiro into a previously filled slot. Previously, the memory was 228464562Sgshapiro freed at removal time. Since removal can happen in a 228564562Sgshapiro signal handler, this may leave the memory map in an 228664562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 228764562Sgshapiro David Cooley of Colby College. 228864562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 228964562Sgshapiro local users in the passwd file. The UserDB code has 229064562Sgshapiro already decided the message will be passed to another host 229164562Sgshapiro for processing. Fix from Tony Landells of Burdett 229264562Sgshapiro Buckeridge Young Limited. 229364562Sgshapiro Support LDAP authorization via either a file containing the 229464562Sgshapiro password or Kerberos V4 using the new map options 229564562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 229664562Sgshapiro distinguished_name is who to login as. The method can be 229764562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 229864562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 229964562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 230064562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 230164562Sgshapiro of Stanford University. 230264562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 230364562Sgshapiro deprecated and will be removed in a future version. 230464562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 230564562Sgshapiro and the map has the column delimiter set, it turns that 230664562Sgshapiro response into a delimiter separated string. The LDAP map 230764562Sgshapiro will traverse multiple entries as well. LDAP alias maps 230864562Sgshapiro automatically set the column delimiter to the comma. 230964562Sgshapiro Based on patch from Booker Bense of Stanford University and 231064562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 231164562Sgshapiro Support return of multiple values for a single LDAP lookup. The 231264562Sgshapiro values to be returned should be in a comma separated string. 231364562Sgshapiro For example, `-v "email,emailother"'. Patch from 231464562Sgshapiro Curtis W. Hillegas of Princeton University. 231564562Sgshapiro Allow the use of LDAP for alias maps. 231664562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 231764562Sgshapiro attributes found in the match will be returned. 231864562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 231964562Sgshapiro breaking up a single entry into multiple entries. This is 232064562Sgshapiro needed for LDAP alias file specifications to allow for 232164562Sgshapiro comma separated key and value strings. 232264562Sgshapiro Keep connections to LDAP server open instead of opening and closing 232364562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 232464562Sgshapiro connections such that multiple maps which use the same 232564562Sgshapiro host, port, bind DN, and authentication will only result in 232664562Sgshapiro a single connection to that host. 232764562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 232864562Sgshapiro Be more careful about checking for errors and freeing memory on 232964562Sgshapiro LDAP lookups. 233064562Sgshapiro Use asynchronous LDAP searches to save memory and network 233164562Sgshapiro resources. 233264562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 233364562Sgshapiro Increase portability to the Netscape LDAP libraries. 233464562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 233564562Sgshapiro replaced with the literal contents of the map lookup key -- 233664562Sgshapiro note that this means a lookup can be done using the LDAP 233764562Sgshapiro special characters. The new '%0' token can be used instead 233864562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 233964562Sgshapiro For example, if the LDAP map specification contains '-k 234064562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 234164562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 234264562Sgshapiro user attribute. Instead, if the LDAP map specification 234364562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 234464562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 234564562Sgshapiro with the name "*". 234664562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 234764562Sgshapiro more than one is returned, it is equivalent to no records 234864562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 234964562Sgshapiro alias dereference option; "-Z size" limits the number of 235064562Sgshapiro matches to return. 235164562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 235264562Sgshapiro LDAP maps. The value should only contain LDAP specific 235364562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 235464562Sgshapiro settings will be used for all LDAP maps unless they are 235564562Sgshapiro specified in the individual map specification ('K' 235664562Sgshapiro command). This option should be set before any LDAP maps 235764562Sgshapiro are defined. 235864562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 235964562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 236064562Sgshapiro Tech. 236164562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 236264562Sgshapiro particular, class entries get much smaller, which can be 236364562Sgshapiro important if you have large classes. 236464562Sgshapiro On network-related temporary failures, record the hostname which 236564562Sgshapiro gave error in the queued status message. Requested by 236664562Sgshapiro Ulrich Windl of the Universitat Regensburg. 236764562Sgshapiro Add new F=% mailer flag to allow for a store and forward 236864562Sgshapiro configuration. Mailers which have this flag will not attempt 236971345Sgshapiro delivery on initial receipt of a message or on queue runs 237064562Sgshapiro unless the queued message is selected using one of the 237164562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 237264562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 237364562Sgshapiro New option ControlSocketName which, when set, creates a daemon 237464562Sgshapiro control socket. This socket allows an external program to 237564562Sgshapiro control and query status from the running sendmail daemon 237664562Sgshapiro via a named socket, similar to the ctlinnd interface to the 237764562Sgshapiro INN news server. Access to this interface is controlled by 237864562Sgshapiro the UNIX file permissions on the named socket on most UNIX 237964562Sgshapiro systems (see sendmail/README for more information). An 238064562Sgshapiro example control program is provided as contrib/smcontrol.pl. 238164562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 238264562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 238364562Sgshapiro number of processors online on the system (if that can be 238464562Sgshapiro determined). For single processor machines, this change 238564562Sgshapiro has no effect. 238664562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 238764562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 238864562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 238964562Sgshapiro Motonori Nakamura of Kyoto University. 239064562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 239164562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 239264562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 239364562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 239464562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 239564562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 239664562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 239764562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 239864562Sgshapiro connection-based denial of service attacks. 239964562Sgshapiro Log basic information about authenticated connections at LogLevel 240064562Sgshapiro 10 or higher. 240164562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 240264562Sgshapiro information (from= syslog line). 240364562Sgshapiro Log the DSN code for each recipient if one is available as a new 240464562Sgshapiro equate (dsn=). 240564562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 240664562Sgshapiro New "ph" map for performing ph queries in rulesets.

Contributed by Mark 240971345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 241064562Sgshapiro Detect temporary lookup failures in the host map if looking up a 241164562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 241264562Sgshapiro Finnish Meteorological Institute. 241364562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 241464562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 241564562Sgshapiro When a forward file points to an alias which runs a program, run 241664562Sgshapiro the program as the default user and the default group, not 241764562Sgshapiro the forward file user. This change also assures the 241864562Sgshapiro :include: directives in aliases are also processed using 241964562Sgshapiro the default user and group. Problem noted by Sergiu 242064562Sgshapiro Popovici of DNT Romania. 242164562Sgshapiro Prevent attempts to save a dead.letter file for a user with 242264562Sgshapiro no home directory (/no/such/directory). Problem noted by 242364562Sgshapiro Michael Brown of Finnigan FT/MS. 242464562Sgshapiro Include message delay and number of tries when logging that a 242564562Sgshapiro message has been completely delivered (LogLevel of 10 or 242664562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 242764562Sgshapiro Log the sender of a message even if none of the recipients were 242864562Sgshapiro accepted. If some of the recipients were rejected, it is 242964562Sgshapiro helpful to know the sender of the message. 243064562Sgshapiro Check the root directory (/) when checking a path for safety. 243164562Sgshapiro Problem noted by John Beck of Sun Microsystems. 243264562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 243364562Sgshapiro interactive and delivering to an alias which resolves to 243464562Sgshapiro multiple files. 243564562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 243664562Sgshapiro greater (see below); the help function doesn't print the 243764562Sgshapiro version of sendmail any longer, instead it is placed in 243864562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 243964562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 244064562Sgshapiro skipped and a version line (#vers) is introduced. The 244164562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 244264562Sgshapiro version is found, a warning is logged. The '#vers' 244364562Sgshapiro directive should be placed at the top of the help file. 244464562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 244564562Sgshapiro disk succeeded. Suggested by Nick Christenson. 244664562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 244764562Sgshapiro length before the attempt. 244864562Sgshapiro If a forward points to a filename for delivery, change to the 244964562Sgshapiro user's uid before checking permissions on the file. This 245064562Sgshapiro allows delivery to files on NFS mounted directories where 245164562Sgshapiro root is remapped to nobody. Problem noted by Harald 245264562Sgshapiro Daeubler of Universitaet Ulm. 245364562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 245464562Sgshapiro host status files, not all files. 245564562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 245664562Sgshapiro in the queue file for the message and set when delivery 245764562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 245864562Sgshapiro Wonderworks Inc. 245964562Sgshapiro Add support for storing information between rulesets using the new 246064562Sgshapiro macro map class. This can be used to store information 246164562Sgshapiro between queue runs as well using $={persistentMacros}. 246264562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 246364562Sgshapiro of Hannover. 246464562Sgshapiro New map class arith to allow for computations in rules. The 246564562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 246664562Sgshapiro as key. The two operands are specified as arguments; the 246764562Sgshapiro lookup returns the result of the computation. For example, 246864562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 246964562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 247064562Sgshapiro Add new syntax for header declarations which decide whether to 247164562Sgshapiro include the header based on a macro rather than a mailer 247264562Sgshapiro flag: 247364562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 247464562Sgshapiro This should be used along with $={persistentMacros}. 247564562Sgshapiro It can be used for adding headers to a message based on 247664562Sgshapiro the results of check_* and header check rulesets. 247764562Sgshapiro Allow new named config file rule check_eoh which is called after 247864562Sgshapiro all of the headers have been collected. The input to the 247964562Sgshapiro ruleset the number of headers and the size of all of the 248064562Sgshapiro headers in bytes separated by $|. This ruleset along with 248164562Sgshapiro the macro storage map can be used to correlate information 248264562Sgshapiro gathered between headers and to check for missing headers. 248364562Sgshapiro See cf/README or doc/op/op.ps for an example. 248464562Sgshapiro Change the default for the MeToo option to True to correspond 248564562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 248664562Sgshapiro option is deprecated and will be removed from a future 248764562Sgshapiro version. 248864562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 248964562Sgshapiro Change the sendmail binary default for SuperSafe to True. 249064562Sgshapiro Display ruleset names in debug and address test mode output 249164562Sgshapiro if referencing a named ruleset. 249264562Sgshapiro New mailer equate m= which will limit the number of messages 249364562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 249464562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 249564562Sgshapiro using it to sort. Now all the same domains are really run 249664562Sgshapiro through the queue together. If they have the same MX host, 249764562Sgshapiro then they will have a much better opportunity to use the 249864562Sgshapiro connection cache if available. This should be a reasonable 249964562Sgshapiro performance improvement. Patch from Randall Winchester of 250064562Sgshapiro the University of Maryland. 250164562Sgshapiro If a message is rejected by a header check ruleset, log who would 250264562Sgshapiro have received the message if it had not been rejected. 250364562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 250464562Sgshapiro queue immediately. No delivery attempt is made. 250564562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 250664562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 250764562Sgshapiro COMMANDS). 250864562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 250964562Sgshapiro but for outgoing connections. 251064562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 251164562Sgshapiro error messages and logging) and Modifiers, i.e. 251264562Sgshapiro a require authentication 251364562Sgshapiro b bind to interface through which mail has 251464562Sgshapiro been received 251564562Sgshapiro c perform hostname canonification 251664562Sgshapiro f require fully qualified hostname 251764562Sgshapiro h use name of interface for outgoing HELO 251864562Sgshapiro command 251964562Sgshapiro C don't perform hostname canonification 252064562Sgshapiro E disallow ETRN (see RFC 2476) 252164562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 252264562Sgshapiro h use name of interface for HELO command 252364562Sgshapiro The version number for queue files (qf) has been incremented to 4. 252464562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 252564562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 252664562Sgshapiro Institutes of Health. 252764562Sgshapiro If a mailer dies, print the status in decimal instead of octal 252864562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 252964562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 253064562Sgshapiro Move message priority from sender to recipient logging. Suggested by 253164562Sgshapiro Ulrich Windl of the Universitat Regensburg. 253264562Sgshapiro Add support for Berkeley DB 3.X. 253364562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 253464562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 253564562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 253664562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 253764562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 253864562Sgshapiro sub-options is set on the command line. Problem noted by 253964562Sgshapiro Graeme Hewson of Oracle. 254064562Sgshapiro Randomize equal preference MX records each time delivery is 254164562Sgshapiro attempted via a new connection to a host instead of once per 254264562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 254364562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 254464562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 254564562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 254664562Sgshapiro to hosts which have dynamically assigned names. 254764562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 254864562Sgshapiro the bounce for the same reason. If the body is not 8-bit 254964562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 255064562Sgshapiro not be included in the bounce. Problem noted by Valdis 255164562Sgshapiro Kletnieks of Virginia Tech. 255264562Sgshapiro The timeout for sending a message via SMTP has been changed from 255364562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 255464562Sgshapiro simply checks for progress on sending data every 5 minutes. 255564562Sgshapiro This will detect the inability to send information quicker 255664562Sgshapiro and reduce the number of processes simply waiting to 255764562Sgshapiro timeout. 255864562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 255964562Sgshapiro interface address structure when loading the system network 256064562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 256164562Sgshapiro Nanoteq. 256264562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 256364562Sgshapiro indicates the number of interfaces to read when probing 256464562Sgshapiro for hostnames and IP addresses for class w ($=w). The 256564562Sgshapiro default value is 512. Based on idea from Reinier 256664562Sgshapiro Bezuidenhout of Nanoteq. 256764562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 256864562Sgshapiro on load average. 256964562Sgshapiro Allow ruleset 0 to have a name.

Patch from 257464562Sgshapiro Luke Mewburn from RMIT University. 257564562Sgshapiro Add a "/quit" command to address test mode. 257664562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 257764562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 257864562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 257964562Sgshapiro Institute. 258064562Sgshapiro The contents of a class can now be copied to another class using 258164562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 258264562Sgshapiro the items in class $={Source} into the class $={Dest}. 258364562Sgshapiro Include original envelope's error transcript in bounces created for 258464562Sgshapiro split (owner-) envelopes to see the original errors when 258564562Sgshapiro the recipients were added. Based on fix from Motonori 258664562Sgshapiro Nakamura of Kyoto University. 258764562Sgshapiro Show reason for permanent delivery errors directly after the 258864562Sgshapiro addresses.

Problem noted by Ezequiel H. Panepucci of 299964562Sgshapiro Yale University. 300064562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 300164562Sgshapiro be used for building. 300264562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 300364562Sgshapiro used for a fresh build. 300464562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 300564562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 300664562Sgshapiro ranlib. 300764562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 300864562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 300964562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 301064562Sgshapiro building of the man pages when defined. Suggested by Bryan 301164562Sgshapiro Costales. 301264562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 301364562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 301464562Sgshapiro installation of the sendmail helpfile and statistics file 301564562Sgshapiro respectively. Suggested by Bryan Costales. 301664562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 301764562Sgshapiro of Siemens Business Services. 301864562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 301964562Sgshapiro stdio library. The new buffered file I/O depends on the 302064562Sgshapiro Torek stdio library. This option can be either portable or 302164562Sgshapiro torek. 302264562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 302364562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 302464562Sgshapiro They should contain the C source files for the object files 302564562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 302664562Sgshapiro will be passed to the 'make depend' stage of compilation. 302764562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 302864562Sgshapiro in the sendmail distribution. Each has the form 302964562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 303064562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 303164562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 303264562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 303364562Sgshapiro building the distribution, but documentation on the changes 303464562Sgshapiro are in devtools/README. 303564562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 303664562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 303764562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 303864562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 303964562Sgshapiro new variable which identifies the root of the source 304064562Sgshapiro directories for all of the programs in the distribution. 304164562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 304264562Sgshapiro time. They can both still be overridden by setting the m4 304364562Sgshapiro macro. 304464562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 304564562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 304664562Sgshapiro build configurations, and places objects in obj.prefix.*/. 304764562Sgshapiro Complains as 'Build -f file' does for existing object 304864562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 304964562Sgshapiro Corporation. 305064562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 305164562Sgshapiro manual pages in the directory tree specified by 305264562Sgshapiro confMANROOTMAN. 305364562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 305464562Sgshapiro preformatted pages from the distribution. The new variable 305564562Sgshapiro confCOPY specifies the copying program. 305664562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 305764562Sgshapiro question.

Suggested by Neil Rickert of 308064562Sgshapiro Northern Illinois University. 308164562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 308264562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 308364562Sgshapiro the Finnish Meteorological Institute. 308464562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 308564562Sgshapiro MAILLOCK when compiling. Also requires linking with 308664562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 308764562Sgshapiro University. 308864562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 308964562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 309064562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 309164562Sgshapiro University. 309264562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 309364562Sgshapiro structure to the beginning of the program. This ensures that 309464562Sgshapiro the getservbyname() is done before any seteuid to a possibly 309564562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 309664562Sgshapiro on a Solaris system, this avoids syslog messages such as, 309764562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 309864562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 309964562Sgshapiro University. 310064562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 310164562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 310264562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 310364562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 310464562Sgshapiro characters (in LMTP mode), mail.local split the incoming 310564562Sgshapiro line up into 2046-character output lines (excluding the 310664562Sgshapiro newline). If an input line was 2047 characters long 310764562Sgshapiro (excluding CR-LF) and the last character was a '.', 310864562Sgshapiro mail.local saw it as the end of input, transfered it to the 310964562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 311064562Sgshapiro If the message was much longer, both sendmail and 311164562Sgshapiro mail.local would deadlock waiting for each other to read 311264562Sgshapiro what they have written. Problem noted by Peter Jeremy of 311364562Sgshapiro Alcatel Australia Limited. 311464562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 311564562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 311664562Sgshapiro Neil Rickert of Northern Illinois University. 311764562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 311864562Sgshapiro timeout to avoid starvation. 311964562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 312064562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 312164562Sgshapiro Infinite Monkeys & Co. 312264562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J.

Sites 360438032Speter which need the ability to override security can use the 360538032Speter DontBlameSendmail option. See the README file for more 360638032Speter information. 360738032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 360838032Speter if maps or alias files are in world writable directories. 360938032Speter This fixes the change added to 8.8.6 to prevent links in these 361038032Speter world writable directories. 361138032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 361238032Speter it is in a world writable directory. 361338032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 361438032Speter tty it may be able to push bytes back to the senders input. 361538032Speter Unfortunately this breaks -v mode.

After this number is reached, sendmail 367538032Speter starts returning "452 Too many recipients" to all RCPT 367638032Speter commands. This can be used to limit the number of recipients 367738032Speter per envelope (in particular, to discourage use of the server 367838032Speter for spamming). Note: a better approach is to restrict 367938032Speter relaying entirely. 368038032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 368138032Speter to ldapx map and added timeout for ldap_open call to 368238032Speter avoid hanging sendmail in the event of hung LDAP servers. 368338032Speter Patch from Booker Bense of Stanford University. 368438032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 370738032Speter of Procter & Gamble. 370838032Speter New DontBlameSendmail option. This option allows administrators to 370938032Speter bypass some of sendmail's file security checks at the expense 371038032Speter of system security. This should only be used if you are 371138032Speter absolutely sure you know the consequences.

In particular, if you 374638032Speter have lots of virtual interfaces, this option will speed up 374738032Speter startup. However, unless you make other arrangements, mail 374838032Speter sent to those addresses will be bounced. 374938032Speter Automatically create alias databases if they don't exist and 375038032Speter AutoRebuildAliases is set. 375138032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 375238032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 375338032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 375438032Speter When determining the client host name ($&{client_name} macro), do 375538032Speter a forward (A) DNS lookup on the result of the PTR lookup 375638032Speter and compare results. If they differ or if the PTR lookup 375738032Speter fails, &{client_name} will contain the IP address 375864562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 375938032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 376038032Speter (i.e, it is like -ax for the temporary failure case, in 376138032Speter contrast to the success case). 376238032Speter New syntax to do limited checking of header syntax. A config line 376338032Speter of the form: 376438032Speter HHeader: $>Ruleset 376538032Speter causes the indicated Ruleset to be invoked on the Header 376638032Speter when read. This ruleset works like the check_* rulesets -- 376738032Speter that is, it can reject mail on the basis of the contents. 376838032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 376938032Speter from hiding their connection information in Received: 377038032Speter headers. 377138032Speter When SingleThreadDelivery is active, deliveries to locked hosts 377238032Speter are skipped. This will cause the delivering process to 377338032Speter try the next MX host or queue the message if no other MX 377438032Speter hosts are available. Suggested by Alexander Litvin. 377538032Speter The [FILE] mailer type now delivers to the file specified in the 377638032Speter A= equate of the mailer definition instead of $u. It also 377738032Speter obeys all of the F= mailer flags such as the MIME 377838032Speter 7/8 bit conversion flags. This is useful for defining 377938032Speter a mailer which delivers to the same file regardless of the 378064562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 378138032Speter Do not assume the identity of a remote connection is root@localhost 378238032Speter if the remote connection closes the socket before the 378338032Speter remote identity can be queried. 378438032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 378538032Speter Some mailers, including procmail, require that the real 378638032Speter uid is left unchanged by sendmail. Problem noted by Per 378738032Speter Hedeland of Ericsson. 378838032Speter No longer is the src/obj*/Makefile selected from a large list -- it 378938032Speter is now generated using the information in BuildTools/OS/ -- 379038032Speter some of the details are determined dynamically via 379138032Speter BuildTools/bin/configure.sh. 379238032Speter The other programs in the sendmail distribution -- mail.local, 379338032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 379438032Speter the new Build method which creates an operating system 379538032Speter specific Makefile using the information in BuildTools. 379638032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 379738032Speter a failure on one message won't affect future messages to the 379838032Speter same host). This is necessary if the remote host sends 379938032Speter a 451 error if the domain of the sender does not resolve 380038032Speter as is common in anti-spam configurations. Problem noted 380138032Speter by Mitchell Blank Jr of Exec-PC. 380238032Speter New "discard" mailer for check_* rulesets and header checking 380338032Speter rulesets. If one of the above rulesets resolves to the 380438032Speter $#discard mailer, the commands will be accepted but the 380538032Speter message will be completely discarded after it is accepting. 380638032Speter This means that even if only one of the recipients 380738032Speter resolves to the $#discard mailer, none of the recipients 380838032Speter will receive the mail. Suggested by Brian Kantor. 380938032Speter All but the last cloned envelope of a split envelope were queued 381038032Speter instead of being delivered.

Suggested by Scott 382738032Speter Gifford of The Internet Ramp. 382838032Speter Sendmail would get a segmentation fault if a mailer exited with an 382938032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 383038032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 383138032Speter Institute. 383238032Speter Separate snprintf/vsnprintf routines into separate file for use by 383338032Speter mail.local. 383438032Speter Allow multiple map lookups on right hand side, e.g., 383538032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 383638032Speter Christophe Wolfhugel of the Pasteur Institute. 383738032Speter Properly generate success DSN messages if requested for aliases 383838032Speter which have owner- aliases.

Patch from 391438032Speter Robert Harker of Harker Systems. 391538032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 391638032Speter directory for certain programs. 391738032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 391838032Speter local mail delivery. By the default, /usr/libexec/mail.local 391938032Speter is used. This is expected to be the mail.local shipped 392038032Speter with 8.9 which is LMTP capable. The path is based on the 392138032Speter new confEBINDIR m4 variable. 392238032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 392338032Speter FEATURE(smrsh). Note that this changes the default from 392438032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 392538032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 392638032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 392738032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 392838032Speter the user to setup different .forward files for 392938032Speter user+detail addressing. 393038032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 393138032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 393238032Speter DontProbeInterfaces, and DontBlameSendmail options. 393338032Speter CONFIG: by default do not allow relaying (that is, accepting mail 393438032Speter from outside your domain and sending it to another host 393538032Speter outside your domain). 393638032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 393738032Speter any site to any site. 393838032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 393938032Speter domain as defined by the 'm' class ($=m) to relay. 394038032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 394138032Speter the MX records of the host portion of an incoming recipient. 394238032Speter CONFIG: new FEATURE(access_db) which turns on the access database 394377349Sgshapiro feature. This database gives you the ability to allow 394438032Speter or refuse to accept mail from specified domains for 394538032Speter administrative reasons. By default, names that are listed 394638032Speter as "OK" in the access db are domain names, not host names. 394738032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 394838032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 394938032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 395038032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 395138032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 395238032Speter of FEATURE(access_db) and class 'R' to lookup individual 395338032Speter host names only. 395438032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 395538032Speter using % addressing is used, e.g. user%site@othersite, 395638032Speter and othersite is in class 'R', the check_rcpt ruleset 395738032Speter will strip @othersite and recheck user@site for relaying. 395838032Speter This feature changes that behavior. It should not be 395938032Speter needed for most installations. 396038032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 396138032Speter domain portion of the mail sender is a local host. This 396238032Speter should only be used if absolutely necessary as it opens 396338032Speter a window for spammers. Patch from Randall S. Winchester of 396438032Speter the University of Maryland. 396538032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 396638032Speter block incoming mail destined for certain recipient 396738032Speter usernames, hostnames, or addresses. 396838032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 396938032Speter refused if the host part of the argument to MAIL FROM: cannot 397038032Speter be located in the host name service (e.g., DNS). 397138032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 397238032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 397338032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 397438032Speter MAIL FROM: senders which do not include a domain. 397538032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 397638032Speter Realtime Blackhole List. You can specify the RBL name 397738032Speter server to contact by specifying it as an optional argument. 397838032Speter The default is rbl.maps.vix.com. For details, see 397938032Speter http://maps.vix.com/rbl/. 398038032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 398138032Speter Local_check_rcpt from check_relay, check_mail, and 398238032Speter check_rcpt. Users with local rulesets should place the 398338032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 398438032Speter returns $#OK, the message is accepted. If the ruleset 398538032Speter returns a mailer, the appropriate action is taken, else 398638032Speter the return of the ruleset is ignored. 398738032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 398838032Speter default to support file, :include:, and program deliveries. 398938032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 399038032Speter pick the proper default value.

Problem noted by Kari Hurtta of the Finnish 412438032Speter Meteorological Institute. 412538032Speter If /usr/tmp/dead.letter already existed, sendmail could not 412638032Speter add additional bounces to it. Problem noted by Thomas J. 412738032Speter Arseneault of SRI International. 412838032Speter If an SMTP mailer used a non-standard port number for the outgoing 412938032Speter connection, it would be displayed incorrectly in verbose mode. 413038032Speter Problem noted by John Kennedy of Cal State University, Chico. 413138032Speter Log the ETRN parameter specified by the client before altering them 413238032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 413338032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 413438032Speter User unknown with bogus delay= values. Change them to log 413538032Speter the same as compliant addresses. Problem noted by Kari E. 413638032Speter Hurtta of the Finnish Meteorological Institute. 413738032Speter Ignore the debug resolver option unless using sendmail debug trace 413838032Speter option for resolver. Problem noted by Greg Nichols of Wind 413938032Speter River Systems. 414038032Speter If SingleThreadDelivery was enabled and the remote server returned a 414138032Speter protocol error on the DATA command, the connection would be 414238032Speter closed but the persistent host status file would not be 414338032Speter unlocked so other sendmail processes could not deliver to 414438032Speter that host. Problem noted by Peter Wemm of DIALix. 414538032Speter If queueing up a message due to an expensive mailer, don't increment 414638032Speter the number of delivery attempts or set the last delivery 414738032Speter attempt time so the message will be delivered on the next 414838032Speter queue run regardless of MinQueueAge. Problem noted by 414938032Speter Brian J. Coan of the Institute for Global Communications. 415038032Speter Authentication warnings of "Processed from queue _directory_" and 415138032Speter "Processed by _username_ with -C _filename_" would be logged 415238032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 415338032Speter of the Finnish Meteorological Institute. 415438032Speter Use a better heuristic for detecting GDBM. 415538032Speter Log null connections on dropped connections. Problem noted by 415638032Speter Jon Lewis of Florida Digital Turnpike. 415738032Speter If class dbm maps are rebuilt, sendmail will now detect this and 415838032Speter reopen the map. Previously, they could give stale 415938032Speter results during a single message processing (but would 416038032Speter recover when the next message was received). Fix from 416138032Speter Joe Pruett of Q7 Enterprises. 416238032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 416338032Speter requests. Problem noted by Kari E. Hurtta of the 416438032Speter Finnish Meteorological Institute. 416538032Speter Do not send a bounce message back to the sender regarding bad 416638032Speter recipients if the SMTP connection is dropped before the 416738032Speter message is accepted. Problem noted by Kari E. Hurtta of the 416838032Speter Finnish Meteorological Institute. 416938032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 417038032Speter sendmail via a UNIX pipe. This will allow rulesets using 417138032Speter $&{client_name} to process without sending the string through 417238032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 417338032Speter A combination of deferred delivery mode, a double bounce situation, 417438032Speter and the inability to save a bounce message to 417538032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 417638032Speter to postmaster but not remove the offending envelope from the 417738032Speter queue causing it to create a new bounce message each time the 417838032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 417938032Speter Associates. 418038032Speter Remove newlines from hostname information returned via DNS. There are 418138032Speter no known security implications of newlines in hostnames as 418238032Speter sendmail filters newlines in all vital areas; however, this 418338032Speter could cause confusing error messages. 418438032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 418538032Speter rejected if any of the specified addresses were bad. This 418638032Speter behavior was modified to only reject the bad addresses and not 418738032Speter the entire message. Problem noted by Jozsef Hollosi of 418838032Speter SuperNet, Inc. 418938032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 419038032Speter Bryan Costales of InfoBeat, Inc. 419138032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 419238032Speter mailers. Problem noted by Kari E. Hurtta of the 419338032Speter Finnish Meteorological Institute. 419438032Speter An error in calculating the available space in the list of addresses 419538032Speter for logging deliveries could cause an address to be silently 419638032Speter dropped. 419738032Speter Include the initial user environment if sendmail is restarted via 419838032Speter a HUP signal. This will give room for the process title. 419938032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 420038032Speter Mail could be delivered without a body if the machine does not 420138032Speter support flock locking and runs out of processes during 420238032Speter delivery. Fix from Chuck Lever of the University of Michigan. 420338032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 420438032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 420538032Speter Institute. 420638032Speter Make sure non-rebuildable database maps are opened before the 420764562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 420838032Speter are needed for verifying the left hand side of the aliases. 420938032Speter Problem noted by Lloyd Parkes of Victoria University. 421038032Speter Make sure sender RFC822 source route addresses are alias expanded for 421138032Speter bounce messages. Problem noted by Juergen Georgi of 421238032Speter RUS University of Stuttgart. 421338032Speter Minor lint fixes. 421438032Speter Return a temporary error instead of a permanent error if an LDAP map 421538032Speter search returns an error. This will allow sequenced maps which 421638032Speter use other LDAP servers to be checked. Fix from Booker Bense 421738032Speter of Stanford University. 421838032Speter When automatically converting from quoted printable to 8bit text do 421938032Speter not pad bare linefeeds with a space. Problem noted by Theo 422038032Speter Nolte of the University of Technology Aachen, Germany. 422138032Speter Portability: 422238032Speter Non-standard C compilers may have had a problem compiling 422338032Speter conf.c due to a standard C external declaration of 422438032Speter setproctitle(). Problem noted by Ted Roberts of 422538032Speter Electronic Data Systems. 422638032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 422738032Speter Jagielski of jaguNET Access Services. 422838032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 422938032Speter Digital UNIX: Digital UNIX (and possibly others) moves 423038032Speter loader environment variables into the loader memory 423138032Speter area. If one of these environment variables (such as 423238032Speter LD_LIBRARY_PATH) was the last environment variable, 423338032Speter an invalid memory address would be used by the process 423438032Speter title routine causing memory corruption. Problem 423538032Speter noted by Sam Hartman of Mesa Internet Systems. 423638032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 423738032Speter chownsafe() to always return 0 even if the OS does 423838032Speter not permit file giveaways. Problem noted by 423938032Speter Yasutaka Sumi of The University of Tokyo. 424064562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 424138032Speter Gerald Rinske of Siemens Business Services VAS. 424238032Speter Linux: Pad process title with NULLs. Problem noted by 424338032Speter Jon Lewis of Florida Digital Turnpike. 424438032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 424538032Speter incorrect value for the number of interfaces. 424638032Speter Problem noted by Chris Loelke of JetStream Internet 424738032Speter Services. 424838032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 424938032Speter Rinske of Siemens Business Services VAS. 425038032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 425138032Speter used on a Solaris machine. Problem noted by 425238032Speter Stephen Ma of Jtec Pty Limited. 425338032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 425438032Speter Services VAS. 425538032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 425638032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 425738032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 425838032Speter Ericsson. 425938032Speter 426064562Sgshapiro8.8.7/8.8.7 1997/08/03 426138032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 426238032Speter an exclusive lock already set -- i.e., almost all systems 426338032Speter except 4.4-BSD derived systems), the initial attempt at 426438032Speter rebuilding aliases file if the database didn't already 426538032Speter exist would fail. Patch from Raymund Will of LST Software 426638032Speter GmbH. 426738032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 426838032Speter Problem noted by Fredrik J�nsson of the Royal Institute 426938032Speter of Technology, Stockholm. 427038032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 427138032Speter some environments could give "multiple definitions" for these 427238032Speter routines during compilation. If using TCP Wrappers, assume 427338032Speter that these routines are included as though they were in the 427438032Speter C library. Patch from Robert La Ferla. 427538032Speter When a NEWDB database map was rebuilt at the same time it was being 427638032Speter used by a queue run, the maps could be left locked for the 427738032Speter duration of the queue run, causing other processes to hang. 427838032Speter Problem noted by Kendall Libby of Shore.NET. 427938032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 428038032Speter mail was passed on without any recipient header. This could 428138032Speter cause problems downstream. Problem noted by Xander Jansen 428238032Speter of SURFnet ExpertiseCentrum. 428338032Speter Give error when GDBM is used with sendmail. GDBM's locking and 428438032Speter linking of the .dir and .pag files interferes with sendmail's 428538032Speter locking and security checks. Problems noted by Fyodor 428638032Speter Yarochkin of the Kyrgyz Republic FreeNet. 428738032Speter Don't fsync qf files if SuperSafe option is not set. 428838032Speter Avoid extra calls to gethostbyname for addresses for which a 428938032Speter gethostbyaddr found no value. Also, ignore any returns 429038032Speter from gethostbyaddr that look like a dotted quad. 429138032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 429238032Speter "may be forged", since at the network level we pretty much 429338032Speter have to assume that the information is good. 429438032Speter In some cases, errors during an SMTP session could leave files 429538032Speter open or locked. 429638032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 429790792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 429838032Speter errors during testing. 429938032Speter Errors in file locking of NEWDB maps had the incorrect file name 430038032Speter printed in the error message. 430138032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 430238032Speter missing parameter were issued, the EHLO behaved like a HELO. 430338032Speter Load limiting never kicked in for incoming SMTP transactions if the 430443730Speter DeliveryMode=background and any recipient was an alias or 430538032Speter had a .forward file. From Nik Conwell of Boston University. 430638032Speter On some non-Posix systems, the decision of whether chown(2) permits 430738032Speter file giveaway was undefined. From Tetsu Ushijima of the 430838032Speter Tokyo Institute of Technology. 430938032Speter Fix race condition that could cause the body of a message to be 431038032Speter lost (so only the header was delivered). This only occurs 431138032Speter on systems that do not use flock(2), and only when a queue 431238032Speter runner runs during a critical section in another message 431338032Speter delivery. Based on a patch from Steve Schweinhart of 431438032Speter Results Computing. 431538032Speter If a qf file was found in a mail queue directory that had a problem 431638032Speter (wrong ownership, bad format, etc.) and the file name was 431738032Speter exactly MAXQFNAME bytes long, then instead of being tried 431838032Speter once, it would be tried on every queue run. Problem noted 431938032Speter by Bryan Costales of Mercury Mail. 432038032Speter If the system supports an st_gen field in the status structure, 432138032Speter include it when reporting that a file has changed after open. 432238032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 432338032Speter This out to be checked as well as reported, since it is 432438032Speter theoretically possible for an attacker to remove a file after 432538032Speter it is opened and replace it with another file that has the 432638032Speter same i-number, but some filesystems (notably AFS) return 432738032Speter garbage in this field, and hence always look like the file 432838032Speter has changed. As a practical matter this is not a security 432938032Speter problem, since the files can be neither hard nor soft links, 433038032Speter and on no filesystem (that I am aware of) is it possible to 433138032Speter have two files on the same filesystem with the same i-number 433238032Speter simultaneously. 433338032Speter Delete the root Makefile from the distribution -- it is only for 433438032Speter use internally, and does not work at customer sites. 433538032Speter Fix botch that caused the second MAIL FROM: command in a single 433638032Speter transaction to clear the entire transaction. Problem 433738032Speter noted by John Kennedy of Cal State University, Chico. 433838032Speter Work properly on machines that have _PATH_VARTMP defined without 433938032Speter a trailing slash. (And a pox on vendors that decide to 434038032Speter ignore the established conventions!) Problem noted by 434138032Speter Gregory Neil Shapiro of WPI. 434238032Speter Internal changes to make it easier to add another protocol family 434338032Speter (intended for IPv6). Patches are from John Kennedy of 434438032Speter CSU Chico. 434538032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 434638032Speter an extra space at the beginning of some lines. Problem 434738032Speter noted by Charles Karney of Princeton University; fix based 434838032Speter on a patch from Christophe Wolfhugel. 434938032Speter Portability: 435038032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 435138032Speter with the _Sendmail_ book, 2nd edition. Note that 435238032Speter the book is actually wrong: _PATH_SENDMAILCF should 435338032Speter be used instead. 435438032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 435538032Speter of Argonne National Laboratory. 435638032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 435738032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 435838032Speter SunOS: Include <memory.h> to fix warning from util.c. From 435938032Speter James Aldridge of EUnet Ltd. 436038032Speter Solaris: Change STDIR (location of status file) to /etc/mail 436138032Speter in Makefiles. 436238032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 436338032Speter Makefiles. Use NEWDB on Linux instead. 436438032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 436538032Speter exists but behaves differently than other OSes. 436638032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 436738032Speter around the problem. Problem noted by Tom Moore of 436838032Speter NCR Corp. 436938032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 437038032Speter noted by Tom Smith of Digital Equipment Corp. 437138032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 437238032Speter noted by Tom Good of the Community Access Information 437338032Speter Resource Network 437438032Speter SCO 4.2: compile problems caused by a change in the type of 437538032Speter the "length" parameters passed to accept, getpeername, 437638032Speter getsockname, and getsockopt. Adds new compile flags 437738032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.

This makes it possible to create a root 442238032Speter owned file in an arbitrary directory by inserting the symlink 442338032Speter into a writable directory after the initial lstat(2) check 442438032Speter determined that the file did not exist. The only verified 442538032Speter example of a system having these odd semantics for O_EXCL 442638032Speter and symbolic links was HP-UX prior to version 9.07. Most 442738032Speter systems do not have the problem, since a exclusive create 442838032Speter of a file disallows symbolic links. Systems that have been 442938032Speter verified to NOT have the problem include AIX 3.x, *BSD, 443038032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 443138032Speter and Ultrix. This is a potential exposure on systems that 443238032Speter have this bug and which do not have a MAILER-DAEMON alias 443338032Speter pointing at a legitimate account, since this will cause old 443438032Speter mail to be dropped in /var/tmp/dead.letter. 443538032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 443638032Speter if maps or alias files are in world writable directories. 443738032Speter If your system has alias maps in writable directories, it 443838032Speter is potentially possible for an attacker to replace the .db 443938032Speter (or .dir and .pag) files by symbolic links pointing at 444038032Speter another database; this can be used either to expose 444138032Speter information (e.g., by pointing an alias file at /etc/spwd.db 444238032Speter and probing for accounts), or as a denial-of-service attack 444338032Speter (by trashing the password database). The fix disallows 444438032Speter symbolic links entirely when rebuilding alias files or on 444538032Speter maps that are in writable directories, and always warns on 444638032Speter writable directories; 8.9 will probably consider writable 444738032Speter directories to be fatal errors. This does not represent an 444838032Speter exposure on systems that have alias files in unwritable 444938032Speter system directories. 445038032Speter SECURITY: disallow .forward or :include: files that are links (hard 445138032Speter or soft) if the parent directory (or any directory in the 445238032Speter path) is writable by anyone other than the owner. This is 445338032Speter similar to the previous case for user files. This change 445438032Speter should not affect most systems, but is necessary to prevent 445538032Speter an attacker who can write the directory from pointing such 445638032Speter files at other files that are readable only by the owner. 445738032Speter SECURITY: Tighten safechown rules: many systems will say that they 445838032Speter have a safe (restricted to root) chown even on files that 445938032Speter are mounted from another system that allows owners to give 446038032Speter away files. The new rules are very strict, trusting file 446138032Speter ownership only in those few cases where the system has 446238032Speter been verified to be at least as paranoid as necessary. 446338032Speter However, it is possible to relax the rules to partially 446438032Speter trust the ownership if the directory path is not world or 446538032Speter group writable. This might allow someone who has a legitimate 446638032Speter :include: file (referenced directly from /etc/aliases) to 446738032Speter become another non-root user if the :include: file is in a 446838032Speter non-writable directory on an NFS-mounted filesystem where 446938032Speter the local system says that giveaway is denied but it is 447038032Speter actually permitted. I believe this to be a very small set 447138032Speter of cases. If in doubt, do not point :include: aliases at 447238032Speter NFS-mounted filesystems. 447338032Speter SECURITY: When setting a numeric group id using the RunAsUser option 447438032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 447538032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 447638032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 447738032Speter The user id was still set properly. Problem noted by Uli 447838032Speter Pralle of the Technical University of Berlin. 447938032Speter Save the initial gid set for use when checking for if the 448038032Speter PrivacyOptions=restrictmailq option is set. Problem reported 448138032Speter by Wolfgang Ley of DFN-CERT. 448238032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 448338032Speter failure on one message won't affect future messages to the 448438032Speter same host). 448538032Speter IP source route printing had an "off by one" error that would 448638032Speter affect any options that came after the route option. Patch 448738032Speter from Theo de Raadt. 448838032Speter The "Message is too large" error didn't successfully bounce the error 448938032Speter back to the sender. Problem reported by Stephen More of 449038032Speter PSI; patch from Gregory Neil Shapiro of WPI. 449138032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 449238032Speter of 5.1.3); it apparently gets used in multiple ways. 449338032Speter Suggested by John Myers of Portola Communications. 449438032Speter Fix possible extra null byte generated during collection if errors 449538032Speter occur at the beginning of the stream. Patch contributed by 449638032Speter Andrey A. Chernov and Gregory Neil Shapiro. 449738032Speter Code changes to avoid possible reentrant call of malloc/free within 449838032Speter a signal handler. Problem noted by John Beck of Sun 449938032Speter Microsystems. 450038032Speter Move map initialization to be earlier so that check_relay ruleset 450138032Speter will have the latest version of the map data. Problem noted 450238032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 450338032Speter If there are fatal errors during the collection phase (e.g., message 450438032Speter too large) don't send the bogus message. 450538032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 450638032Speter have errors and have owner- aliases. Problem noted by Michael 450738032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 450838032Speter Avoid null pointer dereference on illegal Boundary= parameters in 450938032Speter multipart/mixed Content-Type: header. Problem noted by 451038032Speter Richard Muirden of RMIT University. 451138032Speter Always print error messages during newaliases (-bi) even if the 451238032Speter ErrorMode is not set to "print". Fix from Gregory Neil 451338032Speter Shapiro. 451438032Speter Test mode could core dump if you did a /map lookup in an optional map 451538032Speter that could not be opened. Based on a fix from John Beck of 451638032Speter Sun Microsystems. 451738032Speter If DNS is misconfigured so that the last MX record tried points to 451838032Speter a host that does not have an A record, but other MX records 451938032Speter pointed to something reasonable, don't bounce the message 452038032Speter with a "host unknown" error. Note that this should really 452138032Speter be fixed in the zone file for the domain. Problem noted by 452238032Speter Joe Rhett of Navigist, Inc. 452338032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 452438032Speter the message as having been tried; otherwise the next queue 452538032Speter run will not realize that this is a second attempt and will 452638032Speter retry immediately. Problem noted by Bryan Costales of 452738032Speter Mercury Mail. 452838032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 452938032Speter will be run until the later setting of the clock is reached. 453038032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 453138032Speter Morgan Stanley. 453238032Speter If the load average rises above the cutoff threshold (above which 453338032Speter sendmail will not process the queue at all) during a queue 453438032Speter run, abort the queue run immediately. Problem noted by 453538032Speter Bryan Costales of Mercury Mail. 453638032Speter The variable queue processing algorithm (based on the message size, 453738032Speter number of recipients, message precedence, and job age) was 453838032Speter non-functional -- either the entire queue was processed or 453938032Speter none of the queue was processed. The updated algorithm 454038032Speter does no queue run if a single recipient zero size job will 454138032Speter not be run. 454238032Speter If there is a fatal ("panic") message that will cause sendmail to 454338032Speter die immediately, never hold the error message for future 454438032Speter printing. 454538032Speter Force ErrorMode=print in -bt mode so that all errors are printed 454638032Speter regardless of the setting of the ErrorMode option in the 454738032Speter configuration file. Patch from Gregory Neil Shapiro. 454838032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 454938032Speter routine available in one of the libraries. Use it in conf.h. 455038032Speter The -m (match only) flag now works on host class maps. 455138032Speter If class hash or btree maps are rebuilt, sendmail will now detect 455238032Speter this and reopen the map. Previously, they could give 455338032Speter erroneous results during a single message processing 455438032Speter (but would recover when the next message was received). 455538032Speter Don't delete zero length queue files when doing queue runs until the 455638032Speter files are at least ten minutes old. This avoids a potential 455738032Speter race condition: the creator creates the qf file, getting back 455838032Speter a file descriptor. The queue runner locks it and deletes it 455938032Speter because it is zero length. The creator then writes the 456038032Speter descriptor that is now for a disconnected file, and the 456138032Speter job goes away. Based on a suggestion by Bryan Costales. 456238032Speter When determining the "validated" host name ($_ macro), do a forward 456338032Speter (A) DNS lookup on the result of the PTR lookup and compare 456438032Speter results. If they differ or if the PTR lookup fails, tag the 456538032Speter address as "may be forged". 456638032Speter Log null connections (i.e., hosts that connect but do not do any 456738032Speter substantive activity on the connection before disconnecting; 456838032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 456938032Speter Always permit "writes" to /dev/null regardless of the link count. 457038032Speter This is safe because /dev/null is special cased, and no open 457138032Speter or write is ever actually attempted. Patch from Villy Kruse 457238032Speter of TwinCom. 457338032Speter If a message cannot be sent because of a 552 (exceeded storage 457438032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 457538032Speter was given, don't return the body in the bounce, since there 457638032Speter is a very good chance that the message will double-bounce. 457738032Speter Fix possible line truncation if a quoted-printable had an =00 escape 457838032Speter in the body. Problem noted by Charles Karney of the Princeton 457938032Speter Plasma Physics Laboratory. 458038032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 458138032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 458238032Speter Institute. 458338032Speter The MaxDaemonChildren option wasn't applying to queue runs as 458438032Speter documented. Note that this increases the potential denial 458538032Speter of service problems with this option: an attacker can 458638032Speter connect many times, and thereby lock out queue runs as well 458738032Speter as incoming connections. If you use this option, you should 458838032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 458938032Speter to avoid this attack. Failure to limit noted by Matthew 459038032Speter Dillon of BEST Internet Communications. 459138032Speter Always give a message in newaliases if alias files cannot be 459238032Speter opened instead of failing silently. Suggested by Gregory 459338032Speter Neil Shapiro. This change makes the code match the O'Reilly 459438032Speter book (2nd edition). 459538032Speter Some older versions of the resolver could return with h_errno == -1 459638032Speter if no name server could be reached, causing mail to bounce 459738032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 459838032Speter John Beck of SunSoft. 459938032Speter If a :include: file is owned by a user that does not have an entry 460038032Speter in the passwd file, sendmail could dereference a null pointer. 460138032Speter Problem noted by Satish Mynam of Sun Microsystems. 460238032Speter Take precautions to make sure that the SMTP protocol cannot get out 460338032Speter of sync if (for example) an alias file cannot be opened. 460438032Speter Fix a possible race condition that can cause a SIGALRM to come in 460538032Speter immediately after a SIGHUP, causing the new sendmail to die. 460638032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 460738032Speter from Villy Kruse of TwinCom. 460838032Speter Ignore improperly formatted SMTP reply codes. Previously these were 460938032Speter partially processed, which could cause confusing error 461038032Speter returns. 461138032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 461238032Speter on some architectures. 461338032Speter Portability: 461438032Speter A/UX: from Jim Jagielski of NASA/GSFC. 461538032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 461638032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 461738032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 461838032Speter defined. Problem reported by A Sun of the University 461938032Speter of Washington. 462038032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 462138032Speter the system rather than guessing at compile time. 462238032Speter Patch contributed by John Beck of Sun Microsystems. 462338032Speter Intel Paragon: from Wendy Lin of Purdue University. 462438032Speter GNU Hurd: from Miles Bader of the GNU project. 462538032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 462638032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 462738032Speter Unfortunately releasing them opens a race condition, 462838032Speter but there appears to be no fix for this. Patch from 462938032Speter Gregory Neil Shapiro. 463038032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 463138032Speter Solaris: a bug in strcasecmp caused characters with the 463238032Speter high order bit set to apparently randomly match 463338032Speter letters -- for example, $| (0233) matches "i" and "I". 463438032Speter Problem noted by John Gregson of the University of 463538032Speter Cambridge. 463638032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 463738032Speter Kari Hurtta. 463838032Speter IRIX 6.x: Create Makefiles for systems that claim to be 463938032Speter IRIX64 but are 6.2 or higher (so use the regular 464038032Speter IRIX Makefile). 464138032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 464238032Speter Problem noted by Eric Hagberg of Morgan Stanley. 464338032Speter CONFIG: Some canonification was still done for UUCP-like addresses 464438032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 464538032Speter Brian Candler. 464638032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 464738032Speter local names as local. Problem noted by Jeff Polk of BSDI; 464838032Speter fix provided by Gregory Neil Shapiro. 464938032Speter CONFIG: The "local:user" syntax entries in mailertables and other 465038032Speter "mailer:user" syntax locations returned an incorrect value 465138032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 465238032Speter CONFIG: Retain "+detail" information when forwarding mail to a 465338032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 465438032Speter Guenther of Gustavus Adolphus College. 465538032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 465638032Speter rules are the same as for aliasing. Based on a patch from 465738032Speter Gregory Neil Shapiro. 465838032Speter CONFIG: Break up parsing rules into several pieces; this should 465938032Speter have no functional change in this release, but makes it 466038032Speter possible to have better anti-spam rulesets in the future. 466138032Speter CONFIG: Disallow double dots in host names to avoid having the 466238032Speter HostStatusDirectory store status under the wrong name. 466338032Speter In some cases this can be used as a denial-of-service attack. 466438032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 466538032Speter Gregory Neil Shapiro. 466638032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 466738032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 466838032Speter don't include From_, and convert to 8-bit). Suggestions 466938032Speter from Kimmo Suominen and Roderick Schertler. 467064562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 467138032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 467238032Speter was specified, even when it wasn't. 467338032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 467438032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 467538032Speter "slip in" a symbolic link between the lstat(2) call and the 467638032Speter exclusive open. This is only a problem on System V derived 467738032Speter systems that allow an exclusive create on files that are 467838032Speter symbolic links pointing nowhere. 467938032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 468038032Speter not reset back to root, which on some systems would cause 468138032Speter later mailboxes to fail. Also, any partial message would 468238032Speter not be truncated, which could result in repeated deliveries. 468338032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 468438032Speter developers). 468538032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 468638032Speter change to the sendmail map code was made in 8.8.3. Problem 468738032Speter noted by Gregory Neil Shapiro. 468838032Speter MAKEMAP: Give warnings on file problems such as map files that are 468990792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 469038032Speter often run as root and hence has the potential for the same 469138032Speter sorts of problems as alias rebuilds. 469238032Speter MAKEMAP: Change compilation so that it will link properly on 469338032Speter NEXTSTEP. 469438032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 469538032Speter Accept an optional list of arguments following the server 469638032Speter name for the ETRN arguments to use (instead of $=w).

This 470038032Speter Perl script converts GECOS information in the /etc/passwd 470138032Speter file into aliases, allowing for faster access to full name 470238032Speter lookups; it is also clever about adding aliases (to root) 470338032Speter for system accounts. 470438032Speter NEW FILES: 470538032Speter src/safefile.c 470638032Speter cf/ostype/gnuhurd.m4 470738032Speter cf/ostype/irix6.m4 470838032Speter contrib/passwd-to-alias.pl 470938032Speter src/Makefiles/Makefile.IRIX64.6.1 471038032Speter src/Makefiles/Makefile.IRIX64.6.x 471138032Speter RENAMED FILES: 471238032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 471338032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 471438032Speter 471564562Sgshapiro8.8.5/8.8.5 1997/01/21 471638032Speter SECURITY: Clear out group list during startup. Without this, sendmail 471738032Speter will continue to run with the group permissions of the caller, 471838032Speter even if RunAsUser is specified. 471938032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 472038032Speter to any known attack, but it's best to be conservative. 472138032Speter Suggested by Peter Wemm of DIALix. 472238032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 472338032Speter security implications. Patch from Alex Garthwaite of the 472438032Speter University of Pennsylvania. 472538032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 472638032Speter would truncate the address after "Full". Although the -f 472738032Speter syntax is incorrect (since it is in the envelope, it 472838032Speter shouldn't have comments and full names), the failure mode 472938032Speter was unnecessarily awful. 473038032Speter Fix a possible null pointer dereference when converting 8-bit data 473138032Speter to a 7-bit format. Problem noted by Jim Hutchins of 473238032Speter Sandia National Labs and David James of British Telecom. 473338032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 473438032Speter runs. Although this really shouldn't be used (F=9 is for 473538032Speter final delivery only, and using it on an SMTP mailer makes 473638032Speter it possible for a message to be converted from 8->7->8->7 473738032Speter bits several times), it shouldn't have failed with a syserr. 473838032Speter Problem noted by Eric Hagberg of Morgan Stanley. 473938032Speter _Really_ fix the multiple :maildrop code in the user database 474038032Speter module. Patch from Roy Mongiovi of Georgia Tech. 474138032Speter Let F lines in the configuration file actually read root-only 474238032Speter files if the configuration file is safe. Based on a 474338032Speter patch from Keith Reynolds of SCO. 474438032Speter ETRN followed by QUIT would hold the connection open until the queue 474538032Speter run completed. Problem noted by Truck Lewis of TDK 474638032Speter Semiconductor Corp. 474738032Speter It turns out that despite the documentation, the TCP wrappers library 474838032Speter does _not_ log rejected connections. Do the logging ourselves. 474938032Speter Problem noted by Fletcher Mattox of the University of Texas 475038032Speter at Austin. 475138032Speter If sendmail finds a qf file in its queue directory that is an unknown 475238032Speter version (e.g., when backing out to an old version), the 475338032Speter error is reported on every queue run. Change it to only 475438032Speter give the error once (and rename the qf => Qf). Patch from 475538032Speter William A. Gianopoulos of Raytheon Company. 475638032Speter Start a new session when doing background delivery; currently it 475738032Speter ignored signals but didn't start a new signal, that caused 475838032Speter some problems if a background process tried to send mail 475938032Speter under certain circumstances. Problem noted by Eric Hagberg 476038032Speter of Morgan Stanley; fix from Kari Hurtta. 476138032Speter Simplify test for skipping a queue run to just check if the current 476238032Speter load average is >= the queueing load average. Previously 476338032Speter the check factored in some other parameters that caused it 476438032Speter to essentially never skip the queue run. Patch from Bryan 476538032Speter Costales. 476638032Speter If the SMTP server is running in "nullserver" mode (that is, it is 476738032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 476838032Speter (25) commands; this helps prevent a bad guy from putting 476938032Speter you into a tight loop as a denial-of-service attack. Based 477038032Speter on an e-mail conversation with Brad Knowles of AOL. 477138032Speter Slow down when too many "light weight" commands have been issued; 477238032Speter this helps prevent a class of denial-of-service attacks. 477338032Speter The current values and defaults are: 477438032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 477538032Speter MAXHELOCOMMANDS 3 HELO, EHLO 477638032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 477738032Speter MAXETRNCOMMANDS 8 ETRN 477838032Speter These will probably be configurable in a future release. 477938032Speter On systems that have uid_t typedefed to be an unsigned short, programs 478038032Speter that had the F=S flag and no U= equate would be invoked with 478138032Speter the real uid set to 65535 rather than being left unchanged. 478238032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 478338032Speter by Steve Hubert of the University of Washington, Seattle. 478438032Speter Mail that was Quoted-Printable encoded and had a soft line break on 478538032Speter the last line (i.e., an incomplete continuation) had the last 478638032Speter line dropped. Since this appears to be illegal it isn't 478738032Speter clear what to do with it, but flushing the last line seems 478838032Speter to be a better "fail soft" approach. Based on a patch from 478938032Speter Eric Hagberg. 479038032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 479138032Speter bogus HELO command still causes the "Polite people say HELO 479238032Speter first" error message. Problem pointed out by Chris Thomas 479338032Speter of UCLA; patch from John Beck of SunSoft. 479438032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 479571345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 479671345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 479771345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 479838032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 479938032Speter in a DATA transaction to be sticky; these can occur because 480038032Speter a message is too large, and smaller messages should still go 480138032Speter through. Problem noted by Matt Dillon of Best Internet 480238032Speter Communications. 480338032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 480438032Speter had been successfully delivered to the envelope sender. 480538032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 480638032Speter Gregory Neil Shapiro of WPI. 480738032Speter Give better diagnostics on long alias lines. Based on code contributed 480838032Speter by Patrick Gosling of the University of Cambridge. 480938032Speter Increase the number of virtual interfaces that will be probed for 481038032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 481138032Speter PORTABILITY: 481238032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 481338032Speter Toshiaki Nomura of Fujitsu Limited. 481438032Speter SunOS with LDAP support: compile problems with struct timeval. 481538032Speter Patch from Nick Cuccia of TCSI Corporation. 481638032Speter SCO: from Keith Reynolds of SCO. 481738032Speter Solaris: kstat load average computation wasn't being used. 481838032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 481938032Speter (Moscow). 482038032Speter OpenBSD: from Jason Downs of teeny.org. 482138032Speter Altos System V: from Tim Rice. 482238032Speter Solaris 2.5: from Alan Perry of SunSoft. 482338032Speter Solaris 2.6: from John Beck of SunSoft. 482438032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 482538032Speter of Pratt & Whitney <miorelli@pweh.com>. 482638032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 482738032Speter _just_right_ yet. Tweak it again. I'll omit the names 482838032Speter of the "contributors" (quantity two) in this one case. 482938032Speter As of now, NO MORE DISCUSSION about the syntax of the 483038032Speter Received: line. 483138032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 483238032Speter it never inserts that class into the output file. Fix it 483338032Speter so it will honor EXPOSED_USER but will _not_ include root 483438032Speter automatically in this class. Problem noted by Ronan KERYELL 483538032Speter of Centre de Recherche en Informatique de l'�cole Nationale 483638032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 483738032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 483838032Speter such as LUSER_RELAY. This change permits the following 483938032Speter syntaxes: ``local:'' will send to the same user on the 484038032Speter local machine (e.g., in a mailertable entry for "host", 484138032Speter ``local:'' will cause an address addressed to user@host to 484238032Speter go to user on the local machone). ``local:user'' will send 484338032Speter to the named user on the local machine. ``local:user@host'' 484438032Speter is equivalent to ``local:user'' (the host is ignored). In 484538032Speter all cases, the original user@host is passed in $@ (i.e., the 484638032Speter detail information). Inspired by a report from Michael Fuhr. 484738032Speter CONFIG: Strip quotes from the first word of an "error:" host 484838032Speter indication. This lets you set (for example) the LUSER_RELAY 484938032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 485038032Speter of the \" so that the resulting string is properly quoted. 485138032Speter Problem noted by Gregory Neil Shapiro of WPI. 485238032Speter OP.ME: documentation was inconsistent about whether sendmail did a 485338032Speter NOOP or a RSET to probe the connection (it does a RSET). 485438032Speter Inconsistency noted by Deeran Peethamparam. 485538032Speter OP.ME: insert additional blank pages so it will print properly on 485638032Speter a duplex printer. From Matthew Black of Cal State University, 485738032Speter Long Beach. 485838032Speter 485964562Sgshapiro8.8.4/8.8.4 1996/12/02 486038032Speter SECURITY: under some circumstances, an attacker could get additional 486138032Speter permissions by hard linking to files that were group 486238032Speter writable by the attacker. The solution is to disallow any 486338032Speter files that have hard links -- this will affect .forward, 486438032Speter :include:, and output files. Problem noted by Terry 486538032Speter Kyriacopoulos of Interlog Internet Services. As a 486638032Speter workaround, set UnsafeGroupWrites -- always a good idea. 486738032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 486838032Speter is, it is possible to do a denial-of-service attack on 486938032Speter MX hosts that rely on the use of the null MX list. There 487038032Speter is no danger if you have this option turned off (the default). 487138032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 487238032Speter unsafe. I know of no specific attack against this, although 487338032Speter a denial-of-service attack is probably possible, but in theory 487438032Speter you should not be able to safely tweak anything that affects 487538032Speter the permissions that are used when mail is delivered. 487638032Speter Purgestat could go into an infinite loop if one of the host status 487738032Speter directories somehow became empty. Problem noted by Roy 487838032Speter Mongiovi of Georgia Tech. 487938032Speter Processes got "lost" when counting children due to a race condition. 488038032Speter This caused "proc_list_probe: lost pid" messages to be logged. 488138032Speter Problem noted by several people. 488238032Speter On systems with System V SIGCLD child signal semantics (notably AIX 488338032Speter and HP-UX), mail transactions would print the message "451 488438032Speter SMTP-MAIL: lost child: No child processes". Problem noted 488538032Speter by several people. 488638032Speter Miscellaneous compiler warnings on picky compilers (or when setting 488738032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 488838032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 488938032Speter not be persistent between runs, since they are based on the 489038032Speter message rather than the host. Problem noted by Matt Dillon 489138032Speter of Best Internet Communications. 489238032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 489338032Speter of NCR (a.k.a., AT&T Global Information Solutions). 489438032Speter Avoid the possibility of having a child daemon run to completion 489538032Speter (including closing the SMTP socket) before the parent has 489638032Speter had a chance to close the socket; this can cause the parent 489738032Speter to hang for a long time waiting for the socket to drain. 489838032Speter Patch from Don Lewis of TDK Semiconductor. 489938032Speter If the fork() failed in a queue run, the queue runners would not be 490038032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 490138032Speter Some error conditions in ETRN could cause output without an SMTP 490238032Speter status code. Problem noted by Don Lewis. 490338032Speter Multiple :maildrop addresses in the user database didn't work properly. 490438032Speter Patch from Roy Mongiovi of Georgia Tech. 490538032Speter Add ".db" automatically onto any user database spec that does not 490638032Speter already have it; this is for consistency with makemap, the 490738032Speter K line, and the documentation. Inconsistency pointed out 490838032Speter by Roy Mongiovi. 490938032Speter Allow sendmail to be properly called in nohup mode. Patch from 491038032Speter Kyle Jones of UUNET. 491138032Speter Change ETRN to ignore but still update host status files; previously 491238032Speter it would ignore them and not save the updated status, which 491338032Speter caused stale information to be maintained. Based on a patch 491438032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 491538032Speter ETRN ignore the MinQueueAge option. 491638032Speter Patch long term host status to recover more gracefully from an empty 491738032Speter host status file condition. Patch from NAKAMURA Motonori 491838032Speter of Kyoto University. 491938032Speter Several patches to signal handling code to fix potential race 492038032Speter conditions from Don Lewis. 492138032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 492238032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 492338032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 492438032Speter compile flag; use NETINET instead. Solution based on a 492538032Speter patch from Bryan Costales. 492638032Speter PORTABILITY FIXES: 492738032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 492838032Speter /etc/security/passwd file when called as root. This 492938032Speter is very slow on some systems. To speed it up, use the 493038032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 493138032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 493238032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 493338032Speter Glicker of Burrelle's Information Service. 493438032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 493538032Speter from Makoto MATSUSHITA of Osaka University. 493638032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 493738032Speter Leeds University and SASABE Tetsuro of the University 493838032Speter of Tokyo. 493938032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 494038032Speter Services, Inc. 494138032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 494238032Speter I believe this to have only been a problem if you 494338032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 494438032Speter to stick with /etc/sendmail.cf as your One True Path. 494538032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 494638032Speter Martin Laubach of the Technischen Universit�t Wien. 494738032Speter CONFIG: change default Received: line to be multiple lines rather 494838032Speter than one long one. By popular demand. 494938032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 495038032Speter from Jerome Berkman of U.C. Berkeley. 495138032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 495238032Speter to take a very long time. Problem noted by Yoshiro YONEYA 495338032Speter of NTT Software Corporation. 495438032Speter CONTRIB: add etrn.pl, contributed by John Beck. 495538032Speter NEW FILES: 495638032Speter contrib/etrn.pl 495738032Speter 495864562Sgshapiro8.8.3/8.8.3 1996/11/17 495938032Speter SECURITY: it was possible to get a root shell by lying to sendmail 496038032Speter about argv[0] and then sending it a signal. Problem noted 496138032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 496238032Speter best-of-security list. 496338032Speter Log sendmail binary version number in "Warning: .cf version level 496438032Speter (%d) exceeds program functionality (%d) message" -- this 496538032Speter should make it clearer to people that they are running 496638032Speter the wrong binary. 496738032Speter Fix a problem that occurs when you open an SMTP connection and then 496838032Speter do one or more ETRN commands followed by a MAIL command; at 496938032Speter the end of the DATA phase sendmail would incorrectly report 497038032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 497138032Speter noted by Eric Bishop of Virginia Tech. 497238032Speter When doing text-based host canonification (typically /etc/hosts 497338032Speter lookup), a null host name would match any /etc/hosts entry 497438032Speter with space at the end of the line. Problem noted by Steve 497538032Speter Hubert of the University of Washington, Seattle. 497638032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 497738032Speter Problem reported by Tom Smith of Digital Equipment Corp. 497838032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 497938032Speter size PACKETSZ (512) is not sufficient for some nameserver 498038032Speter answers containing very many resource records. The resolver 498138032Speter may also switch to TCP and retry if it detects UDP packet 498238032Speter overflow. Also, allow for the fact that the resolver 498338032Speter routines res_query and res_search return the size of the 498438032Speter *un*truncated answer in case the supplied answer buffer it 498538032Speter not big enough to accommodate the entire answer. Patch from 498638032Speter Eric Wassenaar. 498738032Speter Improvements to MaxDaemonChildren code. If you think you have too 498838032Speter many children, probe the ones you have to verify that they 498938032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 499038032Speter Also, do this probe before growing the vector of children 499138032Speter pids; this previously caused the vector to grow indefinitely 499238032Speter due to a race condition. Problem reported by Kyle Jones of 499338032Speter UUNET. 499438032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 499538032Speter O_EXLOCK to zero; this fools the map compilation code into 499638032Speter thinking that it can avoid race conditions by locking on open. 499738032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 499838032Speter Leif Erlingsson of Data Lege. 499938032Speter Always call res_init() on startup (if compiled in, of course) to 500038032Speter allow the sendmail.cf file to tweak resolver flags; without 500138032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 500238032Speter Andrew Sun of Merrill Lynch. 500338032Speter Improvements to host status printing code. Suggested by Steve Hubert 500438032Speter of the University of Washington, Seattle. 500538032Speter Change MinQueueAge option processing to do the check for the job age 500638032Speter when reading the queue file, rather than at the end; this 500738032Speter avoids parsing the addresses, which can do DNS lookups. 500838032Speter Problem noted by John Beck of InReference, Inc. 500938032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 501038032Speter properly escaped. Problem noted by Peter Nilsson of the 501138032Speter University of Linkoping. 501238032Speter In some cases, sendmail would retain root permissions during queue 501338032Speter runs even if RunAsUser was set. Problem noted by Mark 501438032Speter Thomas of Mark G. Thomas Consulting. 501538032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 501638032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 501738032Speter the envelope, and the receiving SMTP server speaks DSN, then 501838032Speter the DSN would be both generated locally and propagated to the 501938032Speter other end. 502038032Speter The U= mailer field didn't correctly extract the group id if the 502138032Speter user id was numeric. Problem noted by Kenneth Herron of 502238032Speter MCI Telecommunications Communications. 502338032Speter If a message exceeded the fixed maximum size on input, the body of 502438032Speter the message was included in the bounce. Note that this did 502538032Speter not occur if it exceeded the maximum _output_ size. Problem 502638032Speter reported by Kyle Jones of UUNET. 502738032Speter PORTABILITY FIXES: 502838032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 502938032Speter AIX4 defines to use seteuid(2) instead, which 503038032Speter works on 4.1 as well as 4.2. Problem noted by 503138032Speter H�kan Lindholm of interAF, Sweden. 503238032Speter AIX4: use tzname[] vector to determine time zone name. 503338032Speter Patch from NAKAMURA Motonori of Kyoto University. 503438032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 503538032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 503638032Speter Solaris: kstat(3k) support for retrieving the load average. 503738032Speter This adds the LA_KSTAT definition for LA_TYPE. 503838032Speter The outline of the implementation was contributed 503938032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 504038032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 504138032Speter declaration of struct rusage at the top of conf.h; 504238032Speter change it to only be included if you are using gcc, 504338032Speter which is apparently the only compiler that requires 504438032Speter it in the first place. Problem noted by Jeff 504538032Speter Earickson of Colby College. 504638032Speter IRIX: don't default to using gcc. IRIX is a civilized 504738032Speter operating system that comes with a decent compiler 504838032Speter by default. Problem noted by Barry Bouwsma and 504938032Speter Kari Hurtta. 505038032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 505138032Speter consistency with other local mailers. Inconsistency 505238032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 505338032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 505438032Speter overhead) as part of the bestmx_is_local feature, the 505538032Speter domain part was dropped from the name. Patch from Steve 505638032Speter Hubert of the University of Washington, Seattle. 505738032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 505838032Speter end up being translated to the null host name, which would 505938032Speter return any entry in /etc/hosts that had a space at the end 506038032Speter of the line. Problem noted by Steve Hubert of the 506138032Speter University of Washington, Seattle. 506238032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 506338032Speter Polytechnic Institute. 506438032Speter MAKEMAP: tweak hash and btree parameters for better performance. 506538032Speter Patch from Matt Dillon of Best Internet Communications. 506638032Speter NEW FILES: 506738032Speter src/Makefiles/Makefile.Linux.ppc 506838032Speter cf/ostype/aix4.m4 506938032Speter cf/ostype/mklinux.m4 507038032Speter 507164562Sgshapiro8.8.2/8.8.2 1996/10/18 507238032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 507338032Speter changed the code but didn't fix the problem. 507438032Speter PORTABILITY FIXES: 507538032Speter Solaris: Don't use the system getusershell(3); it can 507638032Speter apparently corrupt the heap in some circumstances. 507738032Speter Problem found by Ken Pizzini of Spry, Inc. 507838032Speter OP.ME: document several mailer flags that were accidentally omitted 507938032Speter from this document.

Problem noted 508538032Speter by Dan Bernstein of the University of Illinois at Chicago. 508638032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 508738032Speter message could overflow a buffer if it was converted back 508838032Speter to 8 bits. This caused core dumps and has the potential 508938032Speter for a remote attack. Problem first noted by Gregory Shapiro 509038032Speter of WPI. 509138032Speter Avoid duplicate deliveries of error messages on systems that don't 509238032Speter have flock(2) support. Patch from Motonori Nakamura of 509338032Speter Kyoto University. 509438032Speter Ignore null FallBackMX (V) options. If this option is null (as 509538032Speter opposed to undefined) it can cause "null signature" syserrs 509638032Speter on illegal host names. 509738032Speter If a Base64 encoded text/plain message has no trailing newline in 509838032Speter the encoded text, conversion back to 8 bits will drop the 509938032Speter final line. Problem noted by Pierre David. 510038032Speter If running with a RunAsUser, sendmail would give bogus "cannot 510138032Speter setuid" (or seteuid, or setreuid) messages on some systems. 510238032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 510338032Speter Always print error messages in -bv mode -- previously, -bv would 510438032Speter be absolutely silent on errors if the error mode was sent 510538032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 510638032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 510738032Speter term host status. This is necessary because it is common 510838032Speter to do this when you know a host has just come back up. 510938032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 511038032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 511138032Speter University of Leicester. 511238032Speter If a service (such as NIS) is specified as the last entry in the 511338032Speter service switch, but that service is not compiled in, sendmail 511438032Speter would return a temporary failure when an entry was not found 511538032Speter in the map. This caused the message to be queued instead of 511638032Speter bouncing immediately. Problem noted by Harry Edmon of the 511738032Speter University of Washington. 511838032Speter PORTABILITY FIXES: 511938032Speter Solaris 2.3 had compilation problems in conf.c. Several 512038032Speter people pointed this out. 512138032Speter NetBSD from Charles Hannum of MIT. 512238032Speter AIX4 improvements based on info from Steve Bauer of South 512338032Speter Dakota School of Mines & Technology. 512438032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 512538032Speter Patch from Gil Kloepfer Jr. 512638032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 512738032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 512838032Speter were also in $=w. Problem noted by Zoltan Basti of 512938032Speter Softec. 513038032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 513138032Speter on a patch from Eric Hagberg of Morgan Stanley. 513238032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 513338032Speter of Stanford via Robert La Ferla. 513438032Speter 513564562Sgshapiro8.8.0/8.8.0 1996/09/26 513638032Speter Under some circumstances, Bcc: headers would not be properly 513738032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 513838032Speter Log a warning if the sendmail daemon is invoked without a full 513938032Speter pathname, which prevents "kill -1" from working. I was 514038032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 514138032Speter Fix small buffer overflow. Since the data in this buffer was not 514238032Speter read externally, there was no security problem (and in fact 514338032Speter probably wouldn't really overflow on most compilers). Pointed 514438032Speter out by KIZU takashi of Osaka University. 514538032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 514638032Speter if a FallbackMXHost was specified in the configuration file 514738032Speter -- all mail would be sent to the fallback even if the original 514838032Speter host was accessible. Pointed out by Munenari Hirayama of 514938032Speter NSC (Japan). 515038032Speter A message that didn't terminate with a newline would (sometimes) not 515138032Speter have the trailing "." added properly in the SMTP dialogue, 515238032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 515338032Speter The DaemonPortOptions suboption to bind to a particular address was 515438032Speter incorrect and nonfunctional due to a misunderstanding of the 515538032Speter semantics of binding on a passive socket. Patch from 515638032Speter NIIBE Yutaka of Mitsubishi Research Institute. 515738032Speter Increase the number of MX hosts for a single name to 100 to better 515838032Speter handle the truly huge service providers such as AOL, which 515938032Speter has 13 at the moment (and climbing). In order to avoid 516038032Speter trashing memory, the buffer for all names has only been 516138032Speter slightly increased in size, to 12.8K from 10.2K -- this means 516238032Speter that if a single name had 100 MX records, the average size 516338032Speter of those records could not exceed 128 bytes. Requested by 516438032Speter Brad Knowles of America On Line. 516538032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 516638032Speter Urged by Dan Bernstein of U.C. Berkeley. 516738032Speter Print q_statdate and q_specificity in address structure debugging 516838032Speter printout. 516938032Speter Expand MCI structure flag bits for debugging output. 517038032Speter Support IPv6-style domain literals, which can have colons between 517138032Speter square braces. 517238032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 517338032Speter this is an attempt to track down a bug that one person seems 517438032Speter to be having (it may be a Solaris bug!). 517538032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 517638032Speter this caused the NOTIFY info to sometimes be lost. Problem 517738032Speter pointed out by Claus Assmann of the 517838032Speter Christian-Albrechts-University of Kiel. 517938032Speter The statistics gathered in the sendmail.st file were too high; in 518038032Speter some cases failures (e.g., user unknown or temporary failure) 518138032Speter would count as a delivery as far as the statistics were 518238032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 518338032Speter Systems that don't have flock() would not send split envelopes in 518438032Speter the initial run. Problem pointed out by Leonard Zubkoff of 518538032Speter Dandelion Digital. 518638032Speter Move buffer overflow checking -- these primarily involve distrusting 518738032Speter results that may come from NIS and DNS. 518838032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 518938032Speter include <paths.h> and hence had the wrong pathnames for a few 519038032Speter things like /var/tmp. Reported by Matthew Green. 519138032Speter Conditions were reversed for the Priority: header, resulting in all 519238032Speter values being interpreted as non-urgent except for non-urgent, 519338032Speter which was interpreted as normal. Patch from Bryan Costales. 519438032Speter The -o (optional) flag was being ignored on hash and btree maps 519538032Speter since 8.7.2. Fix from Bryan Costales. 519638032Speter Content-Types listed in class "q" will always be encoded as 519738032Speter Quoted-Printable (or more accurately, will never be encoded 519838032Speter as base64). The class can have primary types (e.g., "text") 519938032Speter or full types (e.g., "text/plain"). Based on a suggestion by 520038032Speter Marius Olafsson of the University of Iceland. 520138032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 520238032Speter dialogue) so it can be passed to programs in mailers. 520338032Speter Define ${bodytype} to be the body type (from the -B flag or the 520438032Speter BODY= ESMTP parameter) so it can be passed to programs in 520538032Speter mailers. 520638032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 520738032Speter flag is set in the mailer descriptor. Suggested by John 520838032Speter Myers of CMU. 520938032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 521038032Speter The command takes a host name; data for that host is 521138032Speter immediately (and asynchronously) flushed. Because this shares 521238032Speter the -qR implementation, other hosts may be attempted, but 521338032Speter there should be no security implications. Implementation 521438032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 521538032Speter Add three new command line flags to pass in DSN parameters: -V envid 521638032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 521738032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 521838032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 521938032Speter that the -N flag applies to all recipients; there is no way 522038032Speter to specify per-address notifications on the command line, 522138032Speter nor is there an equivalent for the ORCPT= per-address 522238032Speter parameter. 522338032Speter Restore LogLevel option to be safe (it can only be increased); 522438032Speter apparently I went into paranoid mode between 8.6 and 8.7 522538032Speter and made it unsafe. Pointed out by Dabe Murphy of the 522638032Speter University of Maryland. 522738032Speter New logging on log level 15: all SMTP traffic. Patches from 522838032Speter Andrew Gross of San Diego Supercomputer Center. 522938032Speter NetInfo property value searching code wasn't stopping when it found 523038032Speter a match. This was causing the wrong values to be found (and 523138032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 523238032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 523338032Speter out by Bill Wisner of Electronics for Imaging that you can't 523438032Speter use the bracket address form for the MAIL_HUB macro, since 523538032Speter that causes the brackets to remain in the envelope recipient 523638032Speter address used for delivery. The simple fix (stripping off the 523738032Speter brackets in the config file) breaks the use of IP literal 523838032Speter addresses. This flag will solve that problem. 523938032Speter Add MustQuoteChars option. This is a list of characters that must 524038032Speter be quoted if they are found in the phrase part of an address 524138032Speter (that is, the full name part). The characters @,;:\()[] are 524238032Speter always in this list and cannot be removed. The default is 524338032Speter this list plus . and ' to match RFC 822. 524438032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 524538032Speter that do not include a host name for back compatibility with 524638032Speter some stupid SMTP clients. Setting this violates RFC 1123 524738032Speter section 5.2.5. 524838032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 524938032Speter rejecting connections if it has more than this many 525038032Speter outstanding children accepting mail. Note that you may 525138032Speter see more processes than this because of outgoing mail; this 525238032Speter is for incoming connections only. 525338032Speter Add ConnectionRateThrottle option. If set to a positive value, the 525438032Speter number of incoming SMTP connections that will be permitted 525538032Speter in a single second is limited to this number. Connections are 525638032Speter not refused during this time, just deferred. The intent is to 525738032Speter flatten out demand so that load average limiting can kick in. 525838032Speter It is less radical than MaxDaemonChildren, which will stop 525938032Speter accepting connections even if all the connections are idle 526038032Speter (e.g., due to connection caching). 526138032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 526238032Speter specifies how long cached information about the state of a 526338032Speter host will be kept before they are considered stale and the 526438032Speter host is retried. If you are using persistent host status 526538032Speter (i.e., the HostStatusDirectory option is set) this will apply 526638032Speter between runs; otherwise, it applies only within a single queue 526738032Speter run and hence is useful only for hosts that have large queues 526838032Speter that take a very long time to run. 526938032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 527038032Speter into being a single line even if they had newlines in them 527138032Speter when read. This is to get around a botch in Lotus Notes. 527238032Speter Text class maps were totally broken -- if you ever retrieved the last 527338032Speter item in a table it would be truncated. Problem noted by 527438032Speter Gregory Neil Shapiro of WPI. 527538032Speter Extend the lines printed by the mailq command (== the -bp flag) when 527638032Speter -v is given to 120 characters; this allows more information 527738032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 527838032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 527938032Speter this was treated as end-of-input. Problem noted by Bryan 528038032Speter Costales. 528138032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 528238032Speter to the queue file. Fix from John Hughes of Atlantic 528338032Speter Technologies, Inc. 528438032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 528538032Speter if this happens in a queue run it can cause nasty delays. 528638032Speter Problem noted by Mark Horton of AT&T. 528738032Speter If userdb entries pointed to userdb entries, and there were multiple 528838032Speter values for a given key, the database cursor would get 528938032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 529038032Speter of Georgia Tech. Fixed by reading all the values and creating 529138032Speter a comma-separated list; thus, the -v output will be somewhat 529238032Speter different for this case. 529338032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 529438032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 529538032Speter of Stanford University. 529638032Speter When envelopes were split due to aliases with owner- aliases, and 529738032Speter there was some error on one of the lists, more than one of 529838032Speter the owners would get the message. Problem pointed out by 529938032Speter Roy Mongiovi of Georgia Tech. 530038032Speter Detect excessive recursion in macro expansions, e.g., $X defined 530138032Speter in terms of $Y which is defined in terms of $X. Problem 530238032Speter noted by Bryan Costales; patch from Eric Wassenaar. 530338032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 530438032Speter some cases get trashed causing bogus From_ lines. Fix from 530538032Speter Kyle Jones of UUNET. 530638032Speter When doing load average initialization, if the nlist call for avenrun 530738032Speter failed, the second and subsequent lookups wouldn't notice 530838032Speter that fact causing bogus load averages to be returned. Noted 530938032Speter by Casper Dik of Sun Holland. 531038032Speter Fix problem with incompatibility with some versions of inet_aton that 531138032Speter have changed the return value to unsigned, so a check for an 531238032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 531338032Speter This could cause mail to addresses such as [foo.com] to bounce 531438032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 531538032Speter Pasteur Institute. 531638032Speter DSNs were inconsistent if a failure occurred during the DATA phase 531738032Speter rather than the RCPT phase: the Action: would be correct, but 531838032Speter the detailed status information would be wrong. Problem noted 531938032Speter by Bob Snyder of General Electric Company. 532038032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 532138032Speter that this is the initial MUA->MTA submission. The flag current 532238032Speter does nothing, but in future releases (when MUAs start using 532338032Speter these flags) it will probably turn on things like DNS 532438032Speter canonification. 532538032Speter Default end-of-line string (E= specification on mailer [M] lines) 532638032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 532738032Speter mailers. 532838032Speter Change the internal definition for the *file* and *include* mailers 532938032Speter to have $u in the argument vectors so that they aren't 533038032Speter misinterpreted as SMTP mailers and thus use \r\n line 533138032Speter termination. This will affect anyone who has redefined 533238032Speter either of these in their configuration file. 533338032Speter Don't assume that IDENT servers close the connection after a query; 533438032Speter responses can be newline terminated. From Terry Kennedy of 533538032Speter St. Peter's College. 533638032Speter Avoid core dumps on erroneous configuration files that have 533738032Speter $#mailer with nothing following. From Bryan Costales. 533838032Speter Avoid null pointer dereference with high debug values in unlockqueue. 533938032Speter Fix from Randy Martin of Clemson University. 534038032Speter Fix possible buffer overrun when expanding very large macros. Fix 534138032Speter from Kyle Jones of UUNET. 534238032Speter After 25 EXPN or VRFY commands, start pausing for a second before 534338032Speter processing each one. This avoids a certain form of denial 534438032Speter of service attack. Potential attack pointed out by Bryan 534538032Speter Costales. 534638032Speter Allow new named (not numbered!) config file rules to do validity 534738032Speter checking on SMTP arguments: check_mail for MAIL commands and 534838032Speter check_rcpt for RCPT commands. These rulesets can do anything 534938032Speter they want; their result is ignored unless they resolve to the 535038032Speter $#error mailer, in which case the indicated message is printed 535138032Speter and the command is rejected. Similarly, the check_compat 535238032Speter ruleset is called before delivery with "from_addr $| to_addr" 535338032Speter (the $| is a meta-symbol used to separate the two addresses); 535438032Speter it can give a "this sender can't send to this recipient" 535538032Speter notification. Note that this patch allows $| to stand alone 535638032Speter in rulesets. 535738032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 535838032Speter that have the name, IP address, and port number (respectively) 535938032Speter of the SMTP client (that is, the entity at the other end of 536038032Speter the connection. These can be used in (e.g.) check_rcpt to 536138032Speter verify that someone isn't trying to relay mail through your 536238032Speter host inappropriately. Be sure to use the deferred evaluation 536338032Speter form, for example $&{client_name}, to avoid having these bound 536438032Speter when sendmail reads the configuration file. 536538032Speter Add new config file rule check_relay to check the incoming connection 536638032Speter information. Like check_compat, it is passed the host name 536738032Speter and host address separated by $| and can reject connections 536838032Speter on that basis. 536938032Speter Allow IDA-style recursive function calls. Code contributed by Mark 537038032Speter Lovell and Paul Vixie. 537138032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 537238032Speter a virtual UUCP address using either a domain address or the $k 537338032Speter macro. Based on code contributed by Mark Lovell and Paul 537438032Speter Vixie. 537538032Speter Add Stanford LDAP map. Requires special libraries that are not 537638032Speter included with sendmail. Contributed by Booker C. Bense 537738032Speter <bbense@networking.stanford.edu>; contact him for support. 537838032Speter See also the src/READ_ME file. 537938032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 538038032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 538138032Speter only for debugging deep bits of code where it is important to 538238032Speter distinguish between the single-character metasymbol $+ and the 538338032Speter two characters $, +. 538438032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 538538032Speter debug_dumpstate. 538638032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 538738032Speter files that are group writable are considered "unsafe" -- that 538838032Speter is, programs and files referenced from such files are not 538938032Speter valid recipients. 539038032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 539138032Speter name that was not in DNS or was a domain-literal. Problem 539238032Speter noted by Tom May. 539338032Speter Change the introduction to error messages to more clearly delineate 539438032Speter permanent from temporary failures; if both existed in a 539538032Speter single message it could be confusing. Suggested by John 539638032Speter Beck of InReference, Inc. 539738032Speter The IngoreDot (i) option didn't work for lines that were terminated 539838032Speter with CRLF. Problem noted by Ted Stockwell of Secure 539938032Speter Computing Corporation. 540038032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 540138032Speter message headers. Problem reported by Matt Dillon of Best 540238032Speter Internet Communications. 540338032Speter Check for bogus characters in the 0200-0237 range; since these are 540438032Speter used internally, very strange errors can occur if those 540538032Speter characters appear in headers. Problem noted by Anders Gertz 540638032Speter of Lysator. 540738032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 540838032Speter recipient mailer has the F=9 flag set, and only works on 540938032Speter text/plain body types. Code contributed by Marius Olafsson 541038032Speter of the University of Iceland. 541138032Speter Special case "postmaster" name so that it is always treated as lower 541238032Speter case in alias files regardless of configuration settings; 541338032Speter this prevents some potential problems where "Postmaster" or 541438032Speter "POSTMASTER" might not match "postmaster". In most cases 541538032Speter this change is a no-op. 541638032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 541738032Speter Costales. 541838032Speter The -a map flag was ignored for dequote maps. Problem noted by 541938032Speter Bryan Costales. 542038032Speter Fix core dump when a lookup of a class "prog" map returns no 542138032Speter response. Patch from Bryan Costales. 542238032Speter Log instances where sendmail is deferring or rejecting connections 542338032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 542438032Speter Include port number in process title for network daemons. Suggested 542538032Speter by Kyle Jones of UUNET. 542638032Speter Send ``double bounces'' (errors that occur when sending an error 542738032Speter message) to the address indicated in the DoubleBounceAddress 542838032Speter option (default: postmaster). Previously they were always 542938032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 543038032Speter Add new mode, -bD, that acts like -bd in all respects except that 543138032Speter it runs in foreground. This is useful for using with a 543238032Speter wrapper that "watches" system services. Suggested by Kyle 543338032Speter Jones of UUNET. 543438032Speter Fix botch in spacing around (parenthesized) comments in addresses 543538032Speter when the comment comes before the address. Patch from 543638032Speter Motonori Nakamura of Kyoto University. 543738032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 543838032Speter that are being bounced to postmaster, rather than "Returned 543938032Speter mail". This permits the person who is postmaster more 544038032Speter easily determine what messages are to their role as 544138032Speter postmaster versus bounces to mail they actually sent. Based 544238032Speter on a suggestion by Motonori Nakamura. 544338032Speter Add new value "time" for QueueSortOrder option; this causes the queue 544438032Speter to be sorted strictly by the time of submission. Note that 544543730Speter this can cause very bad behavior over slow lines (because 544638032Speter large jobs will tend to delay small jobs) and on nodes with 544738032Speter heavy traffic (because old things in the queue for hosts that 544838032Speter are down delay processing of new jobs). Also, this does not 544938032Speter guarantee that jobs will be delivered in submission order 545038032Speter unless you also set DeliveryMode=queue. In general, it should 545138032Speter probably only be used on the command line, and only in 545238032Speter conjunction with -qRhost.domain. In fact, there are very few 545338032Speter cases where it should be used at all. Based on an 545438032Speter implementation by Motonori Nakamura. 545538032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 545638032Speter the same manner as other rulesets. Previously a temporary 545738032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 545838032Speter of Stanford University. 545938032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 546038032Speter 5yz (permanent failure) code. The next MX host will still be 546138032Speter tried if the connection cannot be opened in the first place 546238032Speter or if the MAIL command returns a 4yz (temporary failure) code. 546338032Speter (It's hard to know what to do here, since neither RFC 974 nor 546438032Speter RFC 1123 specify when to proceed to the next MX host.) 546538032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 546638032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 546738032Speter This causes map lookups that get a temporary failure (e.g., 546838032Speter name server failure) to _not_ defer the delivery of the 546938032Speter message. This should only be used if your configuration file 547038032Speter is prepared to do something sensible in this case. Based on 547138032Speter an idea by Gregory Shapiro of WPI. 547238032Speter Fix problem finding network interface addresses. Patch from 547338032Speter Motonori Nakamura. 547438032Speter Don't reject qf entries that are not owned by your effective uid if 547590792Sgshapiro you are not running set-user-ID; this makes management of 547680785Sgshapiro certain kinds of firewall setups difficult. Patch 547780785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 547838032Speter Add persistent host status. This keeps the information normally 547938032Speter maintained within a single queue run in disk files that are 548038032Speter shared between sendmail instances. The HostStatusDirectory 548138032Speter is the directory in which the information is maintained. If 548238032Speter not set, persistent host status is turned off. If not a full 548338032Speter pathname, it is relative to the queue directory. A common 548438032Speter value is ".hoststat". 548538032Speter There are also two new operation modes: 548638032Speter * -bh prints the status of hosts that have had recent 548738032Speter connections. 548838032Speter * -bH purges the host statuses. No attempt is made to save 548938032Speter recent status information. 549038032Speter This feature was originally written by Paul Vixie of Vixie 549138032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 549238032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 549338032Speter with my insistence that things fit cleanly into the V8 549438032Speter framework is gratefully appreciated. 549538032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 549638032Speter operate). Avoids letting two sendmails on the local machine 549764562Sgshapiro open connections to the same remote host at the same time. 549838032Speter This reduces load on the other machine, but can cause mail to 549938032Speter be delayed (for example, if one sendmail is delivering a huge 550038032Speter message, other sendmails won't be able to send even small 550138032Speter messages). Also, it requires another file descriptor (for the 550238032Speter lock file) per connection, so you may have to reduce 550338032Speter ConnectionCacheSize to avoid running out of per-process 550438032Speter file descriptors. Based on the persistent host status code 550538032Speter contributed by Paul Vixie and Mark Lovell. 550638032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 550738032Speter SafeFileEnvironment option is set. Problem noted by Bryan 550838032Speter Costales. 550938032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 551038032Speter file. Problem noted by Bryan Costales. 551138032Speter If a job was aborted using the interrupt signal (e.g., control-C from 551238032Speter the keyboard), on some occasions an empty df file would be 551338032Speter left around; these would collect in the queue directory. 551438032Speter Problem noted by Bryan Costales. 551538032Speter Change the makesendmail script to enhance the search for Makefiles 551638032Speter based on release number. For example, on SunOS 5.5.1, it will 551738032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 551838032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 551938032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 552038032Speter Webmasters. 552138032Speter When creating maps using "newaliases", always map the keys to lower 552238032Speter case when creating the map unless the -f flag is specified on 552338032Speter the map itself. Previously this was done based on the F=u 552438032Speter flag in the local mailer, which meant you could create aliases 552538032Speter that you could never access. Problem noted by Bob Wu of DEC. 552638032Speter When a job was read from the queue, the bits causing notification on 552738032Speter failure or delay were always set. This caused those 552838032Speter notifications to be sent even if NOTIFY=NEVER had been 552938032Speter specified. Problem noted by Steve Hubert of the University 553038032Speter of Washington, Seattle. 553138032Speter Add new configurable routine validate_connection (in conf.c). This 553238032Speter lets you decide if you are willing to accept traffic from 553338032Speter this host. If it returns FALSE, all SMTP commands will return 553438032Speter "550 Access denied". -DTCPWRAPPERS will include support for 553538032Speter TCP wrappers; you will need to add -lwrap to the link line. 553638032Speter (See src/READ_ME for details.) 553738032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 553838032Speter bounces. Some people seemed to think that this could be 553938032Speter confusing (even though it is true). Suggested by Motonori 554038032Speter Nakamura. 554138032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 554238032Speter user early in processing to avoid potential security problems. 554338032Speter However, this means that all .forward and :include: files must 554438032Speter be readable by that user, and all files to be written must be 554538032Speter writable by that user and all programs will be executed by that 554638032Speter user. It is also incompatible with the SafeFileEnvironment 554738032Speter option. In other words, it may not actually add much to 554838032Speter security. However, it should be useful on firewalls and other 554938032Speter places where users don't have accounts and the aliases file is 555038032Speter well constrained. 555138032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 555238032Speter only on the first attempt to delivery to an address. It could 555338032Speter be set to be lower than Timeout.connect on the principle that 555438032Speter the mail should go through quickly to responsive hosts; less 555538032Speter responsive hosts get to wait for the next queue run. 555638032Speter Fix a problem on Solaris that occasionally causes programs 555738032Speter (such as vacation) to hang with their standard input connected 555838032Speter to a UDP port. It also created some signal handling problems. 555938032Speter The problems turned out to be an interaction between vfork(2) 556038032Speter and some of the libraries, particularly NIS/NIS+. I am 556138032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 556238032Speter Change user class map to do the same matching that actual delivery 556338032Speter will do instead of just a /etc/passwd lookup. This adds 556438032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 556538032Speter The Timeout.* options are not safe -- they can be used to create a 556638032Speter denial-of-service attack. Problem noted by Christophe 556738032Speter Wolfhugel. 556843730Speter Don't send PostmasterCopy messages in the event of a "delayed" 556938032Speter notification. Suggested by Barry Bouwsma. 557038032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 557138032Speter option is set, since this disables VERB mode. Suggested 557238032Speter by John Hawkinson of MIT. 557338032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 557438032Speter by Motonori Nakamura of Kyoto University. 557538032Speter Only queue messages on transient .forward open failures if there 557643730Speter were no successful opens. The previous behavior caused it 557738032Speter to queue even if a "fall back" .forward was found. Problem 557838032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 557938032Speter and Computer Science (DISCS), NUS, Singapore. 558038032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 558138032Speter is bouncing because of a MIME error during 8->7 bit conversion; 558238032Speter the encapsulated message will bounce again, causing a loop. 558338032Speter Problem noted by Steve Hubert of the University of Washington. 558438032Speter Create xf (transcript) files using the TempFileMode option value 558538032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 558638032Speter National University of Singapore. 558738032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 558838032Speter detect cases where DefaultUid is set to something that the 558938032Speter system can't cope with. 559038032Speter PORTABILITY FIXES: 559138032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 559238032Speter Atlas International. 559338032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 559438032Speter <bicknell@ufp.org>. 559538032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 559638032Speter work on the first recipient of a message due to a 559738032Speter bug in the getpwent family.

Contributed by 564238032Speter Robert La Ferla of Hot Software. 564338032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 564438032Speter (where "code" is an exit status) on domains (previously 564538032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 564638032Speter Foundation. 564738032Speter CONFIG: hooks for IPv6-style domain literals. 564838032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 564938032Speter if it is undefined the AliasFile option is never set; this 565038032Speter should be transparent for most everyone. Suggested by John 565138032Speter Myers of CMU. 565238032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 565338032Speter domain listed in $=w is masqueraded. With it, only those 565438032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 565538032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 565638032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 565738032Speter hosts under those domains as well as the domain headers 565838032Speter themselves. For example, if a configuration had 565938032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 566038032Speter foo.com would be masqueraded; with it, *.foo.com would be 566138032Speter masqueraded as well. Based on an implementation by Richard 566238032Speter (Pug) Bainter of U. Texas. 566338032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 566438032Speter outgoing addresses.

Texas with updates 566938032Speter from Per Hedeland of Ericsson. 567038032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 567138032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 567238032Speter Keys are either fully qualified addresses or just the host 567338032Speter part (with the @ sign). For example, a table containing: 567438032Speter info@foo.com foo-info 567538032Speter info@bar.com bar-info 567638032Speter @baz.org jane@elsewhere.net 567738032Speter would send all mail destined for info@foo.com to foo-info 567838032Speter (which is presumably an alias), mail addressed to info@bar.com 567938032Speter to bar-info, and anything addressed to anyone at baz.org will 568038032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 568138032Speter and baz.org must all be in $=w. Based on discussions with 568238032Speter a great many people. 568338032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 568438032Speter Suggested by Richard Bainter. 568538032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 568638032Speter "fax" mailer. 568738032Speter CONFIG: allow mailertable entries to resolve to local:user; this 568838032Speter passes the original user@host in to procmail-style local 568938032Speter mailers as the "detail" information to allow them to do 569038032Speter additional clever processing. From Joe Pruett of 569138032Speter Teleport Corporation. Delivery to the original user can 569238032Speter be done by specifying "local:" (with nothing after the colon). 569338032Speter CONFIG: allow any context that takes "mailer:domain" to also take 569438032Speter "mailer:user@domain" to force mailing to the given user; 569538032Speter "local:user" can also be used to do local delivery. This 569638032Speter applies on *_RELAY and in the mailertable entries. Based 569738032Speter on a suggestion by Ribert Kiessling of Easynet. 569838032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 569938032Speter limits the possible domains; this reduces the number of DNS 570038032Speter lookups required to support this feature. For example, 570138032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 570238032Speter to domains under my.site.com. Code contributed by Anthony 570338032Speter Thyssen <anthony@cit.gu.edu.au>. 570438032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 570538032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 570638032Speter of WPI. 570738032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 570838032Speter event you have to define local mailers. Suggested by 570938032Speter Gregory Shapiro of WPI. 571038032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 571138032Speter be misinterpreted as a list:...; syntax. Based on a patch by 571238032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 571338032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 571438032Speter remotely connected. The address host!user was being 571538032Speter converted to host!user@thishost instead of host!user@uurelay. 571638032Speter Problem noted by William Gianopoulos of Raytheon Company. 571738032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 571838032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 571938032Speter "User has moved"; the former wording was confusing if the 572038032Speter new address is still on the local host. Based on a suggestion 572138032Speter by Andreas Luik. 572238032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 572338032Speter However, the class is not pre-initialized to contain root. 572438032Speter Suggested by Gregory Neil Shapiro. 572538032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 572638032Speter Wolfhugel. 572738032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 572838032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 572938032Speter well: this produces a slightly different mailbox format (no 573038032Speter Content-Length: headers), file ownerships and modes are 573138032Speter different (not owned by group mail; mode 600 instead of 660), 573238032Speter and the local mailer flags will have to be tweaked (make them 573338032Speter match bsd4.4) in order to use this mailer. Patches from Paul 573438032Speter Hammann of the Missouri Research and Education Network. 573538032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 573638032Speter was a delivery error, such as if the ownership on the file 573738032Speter was wrong or the mode changed between the initial stat and 573838032Speter the open. Problem reported by William Colburn of the New 573938032Speter Mexico Institute of Mining and Technology. 574038032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 574138032Speter Costales. 574238032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 574338032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 574438032Speter honored. Fix from Michael Scott Shappe. 574538032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 574638032Speter NEW FILES: 574738032Speter src/Makefiles/Makefile.AIX.2 574838032Speter src/Makefiles/Makefile.IRIX.6.2 574938032Speter src/Makefiles/Makefile.maxion 575038032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 575138032Speter src/Makefiles/Makefile.SCO.5.x 575238032Speter src/Makefiles/Makefile.UXPDSV20 575338032Speter mailstats/mailstats.8 575438032Speter praliases/praliases.8 575538032Speter cf/cf/generic-nextstep3.3.mc 575638032Speter cf/feature/genericstable.m4 575738032Speter cf/feature/limited_masquerade.m4 575838032Speter cf/feature/masquerade_entire_domain.m4 575938032Speter cf/feature/virtusertable.m4 576038032Speter cf/ostype/aix2.m4 576138032Speter cf/ostype/altos.m4 576238032Speter cf/ostype/maxion.m4 576338032Speter cf/ostype/solaris2.ml.m4 576438032Speter cf/ostype/uxpds.m4 576538032Speter contrib/re-mqueue.pl 576638032Speter DELETED FILES: 576738032Speter src/Makefiles/Makefile.Solaris 576838032Speter contrib/xla/README 576938032Speter contrib/xla/xla.c 577038032Speter RENAMED FILES: 577138032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 577238032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 577338032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 577438032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 577538032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 577638032Speter 577764562Sgshapiro8.7.6/8.7.3 1996/09/17 577838032Speter SECURITY: It is possible to force getpwuid to fail when writing the 577938032Speter queue file, causing sendmail to fall back to running programs 578038032Speter as the default user. This is not exploitable from off-site. 578138032Speter Workarounds include using a unique user for the DefaultUser 578238032Speter (old u & g options) and using smrsh as the local shell. 578338032Speter SECURITY: fix some buffer overruns; in at least one case this allows 578438032Speter a local user to get root. This is not known to be exploitable 578538032Speter from off-site. The workaround is to disable chfn(1) commands. 578638032Speter 578764562Sgshapiro8.7.5/8.7.3 1996/03/04 578838032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 578938032Speter in some case cause connections to hang or messages to have 579038032Speter extra spaces in odd places. Patch from Eric Wassenaar; 579138032Speter reports from Eric Hall of Chiron Corporation, Stephen 579238032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 579338032Speter and others. 579438032Speter 579564562Sgshapiro8.7.4/8.7.3 1996/02/18 579638032Speter SECURITY: In some cases it was still possible for an attacker to 579738032Speter insert newlines into a queue file, thus allowing access to 579838032Speter any user (except root). 579938032Speter CONFIG: no changes -- it is not a bug that the configuration 580038032Speter version number is unchanged. 580138032Speter 580264562Sgshapiro8.7.3/8.7.3 1995/12/03 580338032Speter Fix botch in name server timeout in RCPT code; this problem caused 580438032Speter two responses in SMTP, which breaks things horribly. Fix 580538032Speter from Gregory Neil Shapiro of WPI. 580638032Speter Verify that L= value on M lines cannot be negative, which could cause 580738032Speter negative array subscripting. Not a security problem since 580838032Speter this has to be in the config file, but it could have caused 580938032Speter core dumps. Pointed out by Bryan Costales. 581038032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 581138032Speter Costales. 581238032Speter PORTABILITY FIXES: 581338032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 581438032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 581538032Speter order. Tweak it to work properly. Based on fixes 581638032Speter from Fletcher Mattox of UTexas and Betty Lee of 581738032Speter Stanford University. 581838032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 581938032Speter Deficiency pointed out by Bryan Costales of ICSI. 582038032Speter 582164562Sgshapiro8.7.2/8.7.2 1995/11/19 582238032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 582338032Speter OperatorChars, and UnixFromLine options. They were not 582438032Speter properly repaired in 8.7.1. 582538032Speter Completely delete the Bcc: header if and only if there are other 582638032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 582738032Speter last being a historic botch, of course). If Bcc: is the 582838032Speter only recipient header in the message, its value is tossed, 582943730Speter but the header name is kept. The old behavior (always keep 583038032Speter the header name and toss the value) allowed primary recipients 583138032Speter to see that a Bcc: went to _someone_. 583238032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 583338032Speter sender to <address> using -f'' syslog messages. Suggested 583438032Speter by Kari Hurtta. 583538032Speter If a sequence or switch map lookup entry gets a tempfail but then 583638032Speter continues on to another map type, but the name is not found, 583738032Speter return a temporary failure from the sequence or switch map. 583838032Speter For example, if hosts search ``dns files'' and DNS fails 583938032Speter with a tempfail, the hosts map will go on and search files, 584038032Speter but if it fails the whole thing should be a tempfail, not 584138032Speter a permanent (host unknown) failure, even though that is the 584238032Speter failure in the hosts.files map. This error caused hard 584338032Speter bounces when it should have requeued. 584438032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 584590792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 584638032Speter working properly due to excessive paranoia. Pointed out by 584738032Speter John Hawkinson of Panix. 584838032Speter An SMTP RCPT command referencing a host that gave a nameserver 584938032Speter timeout would return a 451 command (8.6 accepted it and 585043730Speter queued it locally). Revert to the 8.6 behavior in order 585138032Speter to simplify queue management for clustered systems. Suggested 585238032Speter by Gregory Neil Shapiro of WPI. The same problem could break 585338032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 585438032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 585538032Speter Infobiogen. 585638032Speter Fix possible buffer overflow in munchstring(). This was not a security 585738032Speter problem because you couldn't specify any argument to this 585838032Speter without first giving up root privileges, but it is still a 585938032Speter good idea to avoid future problems. Problem noted by John 586038032Speter Hawkinson and Sam Hartman of MIT. 586138032Speter ``452 Out of disk space for temp file'' messages weren't being 586238032Speter printed. Fix from David Perlin of Nanosoft. 586343730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 586438032Speter is not set, since this is required to get the actual DSNs 586538032Speter created. Problem pointed out by John Gardiner Myers of CMU. 586638032Speter Log permission problems that cause .forward and :include: files to 586738032Speter be untrusted or ignored on log level 12 and higher. Suggested 586838032Speter by Randy Martin of Clemson University. 586938032Speter Allow user ids in U= clauses of M lines to have hyphens and 587038032Speter underscores. 587138032Speter Fix overcounting of recipients -- only happened when sending to an 587238032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 587338032Speter of Systems and Computer Technology Corporation. 587438032Speter If a message is sent to an address that fails, the error message that 587538032Speter is returned could show some extraneous "success" information 587638032Speter included even if the user did not request success notification, 587738032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 587838032Speter Config files that had no AliasFile definition were defaulting to 587938032Speter using /etc/aliases; this caused problems with nullclient 588038032Speter configurations. Change it back to the 8.6 semantics of 588138032Speter having no local alias file unless it is declared. Problem 588238032Speter noted by Charles Karney of Princeton University. 588338032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 588438032Speter Costales of ICSI. 588538032Speter Map lookups of class "userdb" maps were always case sensitive; they 588638032Speter should be controlled by the -f flag like other maps. Pointed 588738032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 588838032Speter Fix problem that caused some addresses to be passed through ruleset 5 588938032Speter even when they were tagged as "sticky" by prefixing the 589038032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 589138032Speter Technological University. 589238032Speter When converting a message to Quoted-Printable, prevent any lines with 589338032Speter dots alone on a line by themselves. This is because of the 589438032Speter preponderance of broken mailers that still get this wrong. 589538032Speter Code contributed by Per Hedeland of Ericsson. 589638032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 589738032Speter out by Bjart Kvarme of USIT/UiO (Norway). 589838032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 589938032Speter Requested by Allan Johannesen. 590038032Speter Delete check for text format of alias files -- it should be legal 590138032Speter to have the database format of the alias files without the 590238032Speter text version. Problem pointed out by Joe Rhett of Navigist, 590338032Speter Inc. 590438032Speter If "Ot" was specified with no value, the TZ variable was not properly 590538032Speter imported from the environment.

Patch from Booker C. Bense of Stanford 590938032Speter University. 591038032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 591138032Speter the parent should do this. Fix from Brian Coan of the 591238032Speter Association for Progressive Communications. 591338032Speter If MinQueueAge was set and a message was considered but not run 591438032Speter during a queue run and the Timeout.queuereturn interval was 591538032Speter reached, a "timed out" error message would be returned that 591638032Speter didn't include the failed address (and claimed to be a warning 591738032Speter even though it was fatal). The fix is to not return such 591838032Speter messages until they are actually tried, i.e., in the next 591938032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 592038032Speter SINTEF RUNIT, Oslo. 592138032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 592238032Speter that have the hes_getmailhost() routine.

Bug 596938032Speter pointed out by John Hawkinson of MIT. 597038032Speter Fix strange case of an executable called by a program map that 597138032Speter returns a value but also a non-zero exit status; this 597238032Speter would give contradictory results in the higher level; in 597338032Speter particular, the default clause in the map lookup would be 597438032Speter ignored. Change to ignore the value if the program returns 597538032Speter non-zero exit status. From Tom Moore of AT&T GIS. 597638032Speter Shorten parameters passed to syslog() in some contexts to avoid a 597738032Speter bug in many vendors' implementations of that routine. Although 597838032Speter this isn't really a bug in sendmail per se, and my solution 597938032Speter has to assume that syslog() has at least a 1K buffer size 598038032Speter internally (I know some vendors have shortened this 598138032Speter dramatically -- they're on their own), sendmail is a popular 598238032Speter target. Also, limit the size of %s arguments in sprintf. 598338032Speter These both have possible security implications. Solutions 598438032Speter suggested by Casper Dik of Sun's Network Security Group 598538032Speter (Holland), Mark Seiden, and others. 598638032Speter Fix a problem that might cause a non-standard -B (body type) 598738032Speter parameter to be passed to the next server with undefined 598838032Speter results. This could have security implications. 598938032Speter If a filesystem was at > 100% utilization, the freediskspace() 599038032Speter routine incorrectly returned an error rather than zero. 599138032Speter Problem noted by G.

Fixes from Randy 599838032Speter Martin <WOLF@CLEMSON.EDU> 599938032Speter When sendmail starts up on systems that have no fully qualified 600038032Speter domain name (FQDN) anywhere in the first matching host map 600138032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 600238032Speter sendmail would sleep to try to find a FQDN, which it really 600338032Speter really needs. This has been changed to fall through to the 600438032Speter next map type if it can't find a FQDN -- i.e., if the hosts 600538032Speter file doesn't have a FQDN, it will try dns even though the 600638032Speter short name was found in /etc/hosts. This is probably a crock, 600738032Speter but many people have hosts files without FQDNs. Remember: 600838032Speter domain names are your friends. 600938032Speter Log a high-priority message if you can't find your FQDN during startup. 601038032Speter Suggested by Simon Barnes of Schlumberger Limited. 601138032Speter When using Hesiod, initialize it early to improve error reporting. 601238032Speter Patch from Don Lewis of Silicon Systems, Inc. 601338032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 601438032Speter connection timeout in the kernel. Add a new "connect" timeout 601538032Speter to limit this time. Defaults to zero (use whatever the 601638032Speter kernel provides). Based on code contributed by J.R. Oldroyd 601738032Speter of TerraNet. 601838032Speter Under some circumstances, a failed message would not be properly 601938032Speter removed from the queue, causing tons of bogus error messages. 602038032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 602138032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 602238032Speter of WPI. 602338032Speter PORTABILITY FIXES: 602438032Speter On IRIX 5.x, there was an inconsistency in the setting 602538032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 604138032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 604238032Speter otherwise the F=S causes the From_ line to imply that root is 604338032Speter the sender. Problem pointed out by Claude Scarpelli of 604438032Speter Infobiogen (France). 604538032Speter NEW FILES: 604638032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 604738032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 604838032Speter src/Makefiles/Makefile.UXPDS 604938032Speter 605064562Sgshapiro8.7/8.7 1995/09/16 605138032Speter Fix a problem that could cause sendmail to run out of file 605238032Speter descriptors due to a trashed data structure after a 605338032Speter vfork.

This was used "safely" in the sense 605938032Speter that it only did a stat, but it would have set the 606038032Speter map modification time improperly. Problem pointed out 606138032Speter by Roy Mongiovi of Georgia Tech. 606238032Speter Clean up the Subject: line on warning messages and return 606338032Speter receipts so that they don't say "Returned mail:"; this 606438032Speter can be confusing. 606538032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 606638032Speter useful enough to make it worthwhile printing on "-d". 606738032Speter Avoid logging alias statistics every time you read the alias 606838032Speter file on systems with no database method compiled in. 606938032Speter If you have a name with a trailing dot, and you try looking it 607038032Speter up using gethostbyname without the dot (for /etc/hosts 607138032Speter compatibility), be sure to turn off RES_DEFNAMES and 607238032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 607338032Speter Problem noted by Charles Amos of the University of 607438032Speter Maryland. 607538032Speter Don't do timeouts in collect if you are not running SMTP. 607638032Speter There is nothing that says you can't have a long 607738032Speter running program piped into sendmail (possibly via 607838032Speter /bin/mail, which just execs sendmail). Problem reported 607938032Speter by Don "Truck" Lewis of Silicon Systems. 608038032Speter Try gethostbyname() even if the DNS lookup fails iff option I 608138032Speter is not set. This allows you to have hosts listed in 608238032Speter NIS or /etc/hosts that are not known to DNS. It's normally 608338032Speter a bad idea, but can be useful on firewall machines. This 608438032Speter should really be broken out on a separate flag, I suppose. 608538032Speter Avoid compile warnings against BIND 4.9.3, which uses function 608638032Speter prototypes.

From Kyle Jones of UUNET. 609138032Speter SECURITY: avoid denial-of-service attacks possible by destroying 609238032Speter the alias database file by setting resource limits low. 609338032Speter This involves adding two new compile-time options: 609438032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 609538032Speter available) and HASULIMIT (indicating that ulimit(2) support 609638032Speter is available -- the Release 3 form is used). The former 609738032Speter is assumed on BSD-based systems, the latter on System 609838032Speter V-based systems. Attack noted by Phil Brandenberger of 609938032Speter Swarthmore University. 610038032Speter New syntaxes in test (-bt) mode: 610138032Speter ``.Dmvalue'' will define macro "m" to "value". 610238032Speter ``.Ccvalue'' will add "value" to class "c". 610338032Speter ``=Sruleset'' will dump the contents of the indicated 610438032Speter ruleset. 610538032Speter ``=M'' will display the known mailers. 610638032Speter ``-ddebug-spec'' is equivalent to the command-line 610738032Speter -d debug flag. 610838032Speter ``$m'' will print the value of macro $m. 610938032Speter ``$=c'' will print the contents of class $=c. 611038032Speter ``/mx host'' returns the MX records for ``host''. 611138032Speter ``/parse address'' will parse address, returning the value of 611238032Speter crackaddr (essentially, the comment information) 611338032Speter and the parsed address. 611438032Speter ``/try mailer address'' will rewrite address into the form 611538032Speter it will have when presented to the indicated mailer. 611638032Speter ``/tryflags flags'' will set flags used by parsing. The 611738032Speter flags can be `H' for header or `E' for envelope, 611838032Speter and `S' for sender or `R' for recipient. These 611938032Speter can be combined, so `HR' sets flags for header 612038032Speter recipients. 612138032Speter ``/canon hostname'' will try to canonify hostname and 612238032Speter return the result. 612338032Speter ``/map mapname key'' will look up `key' in the indicated 612438032Speter `mapname' and return the result. 612538032Speter Somewhat better handling of UNIX-domain socket addresses -- it 612638032Speter should show the pathname rather than hex bytes. 612738032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 612838032Speter the header for envelope sender information and uses 612938032Speter CR-LF as message terminators. It was thought to be 613038032Speter obsolete (used only for Arpanet NCP protocols), but it 613138032Speter turns out that the UK ``Grey Book'' protocols require 613238032Speter that functionality. 613338032Speter Fix a fix in previous release -- if gethostname and gethostbyname 613438032Speter return a name without dots, and if an attempt to canonify 613538032Speter that name fails, wait one minute and try again. This can 613638032Speter result in an extra 60 second delay on startup if your system 613738032Speter hostname (as returned by hostname(1)) has no dot and no names 613838032Speter listed in /etc/hosts or your NIS map have a dot. 613938032Speter Check for proper domain name on HELO and EHLO commands per 614038032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 614138032Speter of Michigan Technological University. 614238032Speter Relax chownsafe rules slightly -- old version said that if you 614338032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 614438032Speter if fpathconf returned EINVAL or ENOSYS), assume that 614538032Speter chown is not safe. The new version falls back to whether 614638032Speter you are on a BSD system or not. This is important for 614738032Speter SunOS, which apparently always returns one of those 614838032Speter error codes. This impacts whether you can mail to files 614938032Speter or not. 615038032Speter Syntax errors such as unbalanced parentheses in the configuration 615138032Speter file could be omitted if you had "Oem" prior to the 615238032Speter syntax error in the config file. Change to always print 615338032Speter the error message. It was especially weird because it 615438032Speter would cause a "warning" message to be sent to the Postmaster 615538032Speter for every message sent (but with no transcript). Problem 615638032Speter noted by Gregory Paris of Motorola. 615738032Speter Rewrite collect and putbody to handle full 8-bit data, including 615838032Speter zero bytes.

This is to handle the 622738032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 622838032Speter assume that ``group name:'' is a comment on the first 622938032Speter address and the ``;'' is a comment on the last address). 623038032Speter This requires config file support to get right. It does 623138032Speter understand that :: is NOT this syntax, and can be turned 623238032Speter off completely by setting the ColonOkInAddresses option. 623338032Speter Level 6 config files added with new mailer flags: 623438032Speter A Addresses are aliasable. 623538032Speter i Do udb rewriting on envelope as well as header 623638032Speter sender lines. Applies to the from address mailer 623738032Speter flags rather than the recipient mailer flags. 623838032Speter j Do udb rewriting on header recipient addresses. 623938032Speter Applies to the sender mailer flags rather than the 624038032Speter recipient mailer flags. 624138032Speter k Disable check for loops when doing HELO command. 624238032Speter o Always run as the mail recipient, even on local 624338032Speter delivery. 624438032Speter w Check for an /etc/passwd entry for this user. 624538032Speter 5 Pass addresses through ruleset 5. 624638032Speter : Check for :include: on this address. 624738032Speter | Check for |program on this address. 624838032Speter / Check for /file on this address. 624938032Speter @ Look up sender header addresses in the user 625038032Speter database. Applies to the mailer flags for the 625138032Speter mailer corresponding to the envelope sender 625238032Speter address, rather than to recipient mailer flags. 625338032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 625438032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 625538032Speter mailers, and the ColonOkInAddresses option. 625638032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 625738032Speter John Beck of Hewlett-Packard, who generously contributed 625838032Speter their implementation to me, which I then didn't use (see 625938032Speter mime.c for an explanation of why). This adds the 626038032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 626138032Speter to control handling of 8-bit data. These have to cope with 626238032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 626338032Speter 8-bit data that is entered without declaring it as 8-bit 626438032Speter MIME -- technically this is illegal according to the 626538032Speter specs) and labelled 8-bit data (that is, it was declared 626638032Speter as 8BITMIME in the ESMTP session or by using the 626738032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 626838032Speter set then 8-bit data is sent to non-8BITMIME machines 626938032Speter instead of converting to 7 bit (essentially using 627038032Speter just-send-8 semantics). The values for EightBitMode are: 627138032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 627238032Speter any necessary conversion of 8BITMIME to 7BIT 627338032Speter (essentially, the full MIME option). 627438032Speter p pass unlabelled 8-bit input, but convert labelled 627538032Speter 8BITMIME input to 7BIT as required (default). 627638032Speter s strict adherence: reject unlabelled 8-bit input, 627738032Speter convert 8BITMIME to 7BIT as required. The F=8 627838032Speter flag is ignored. 627938032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 628038032Speter the setting of F=8. 628138032Speter Add new internal class 'n', which is the set of MIME Content-Types 628238032Speter which can not be 8 to 7 bit encoded because of other 628338032Speter considerations. Types "multipart/*" and "message/*" are 628438032Speter never directly encoded (although their components can be). 628538032Speter Add new internal class 's', which is the set of subtypes of the 628638032Speter MIME message/* content type that can be treated as though 628738032Speter they are an RFC822 message. It is predefined to have 628838032Speter "rfc822". Suggested By Kari Hurtta. 628938032Speter Add new internal class 'e'. This is the set of MIME 629038032Speter Content-Transfer-Encodings that can be converted to 629138032Speter a seven bit format (Quoted-Printable or Base64). It is 629238032Speter preinitialized to contain "7bit", "8bit", and "binary". 629338032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 629438032Speter short name) to set the default character set to use in the 629538032Speter Content-Type: header when doing encoding of an 8-bit message 629638032Speter which isn't marked as MIME into MIME format. If the C= 629738032Speter parameter is set on the Envelope From address, use that as 629838032Speter the default encoding; else use the DefaultCharSet option. 629938032Speter If neither is set, it defaults to "unknown-8bit" as 630038032Speter suggested by RFC 1428 section 3. 630138032Speter Allow ``U=user:group'' field in mailer definition to set a default 630238032Speter user and group that a mailer will be executed as. This 630338032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 630438032Speter also set, it is the uid/gid that will always be used (that 630538032Speter is, the controlling address is ignored). The values may be 630638032Speter numeric or symbolic; if only a symbolic user is given (no 630738032Speter group) that user's default group in the passwd file is used 630838032Speter as the group. Based on code donated by Chip Rosenthal of 630938032Speter Unicom. 631038032Speter Allow `u' option to also accept user:group as a value, in the same 631138032Speter fashion as the U= mailer option. 631238032Speter Add the symbolic time zone name in the Arpanet format dates (as 631338032Speter a comment). This adds a new compile-time configuration 631438032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 631538032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 631638032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 631738032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 631838032Speter timezone()), or TZ_NONE (don't include the comment). Code 631938032Speter from Chip Rosenthal. 632038032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 632138032Speter For example, 632238032Speter O Timeout.helo = 2m 632338032Speter There are also two new suboptions "queuereturn" and 632438032Speter "queuewarn"; these subsume the old T option. Thus, to 632538032Speter set them both the preferred new syntax is 632638032Speter O Timeout.queuereturn = 5d 632738032Speter O Timeout.queuewarn = 4h 632838032Speter Sort queue by host name instead of by message priority if the 632938032Speter QueueSortOrder option (no short name) is set is set to 633038032Speter ``host''. This makes better use of the connection cache, 633138032Speter but may delay more ``interactive'' messages behind large 633238032Speter backlogs under some circumstances. This is probably a 633338032Speter good option if you have high speed links or don't do lots 633438032Speter of ``batch'' messages, but less good if you are using 633538032Speter something like PPP on a 14.4 modem. Based on code 633638032Speter contributed by Roy Mongiovi of Georgia Tech (my main 633738032Speter contribution was to make it configurable). 633838032Speter Save i-number of df file in qf file to simplify rebuilding of queue 633938032Speter after disastrous disk crash. Suggested by Kyle Jones of 634038032Speter UUNET; closely based on code from KJS DECWRL code written 634138032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 634238032Speter are NOT back compatible with 8.6 -- that is, you can convert 634338032Speter from 8.6 to 8.7, but not the other direction. 634438032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 634538032Speter route-addrs in envelopes; this is because in some cases 634638032Speter they can be sent to the shell, which interprets them as 634738032Speter I/O redirection. 634838032Speter Don't include error file (option E) with return-receipts; this 634938032Speter can be confusing. 635038032Speter Don't send "Warning: cannot send" messages to owner-* or 635138032Speter *-request addresses. Suggested by Christophe Wolfhugel 635238032Speter of the Institut Pasteur, Paris. 635338032Speter Allow -O command line flag to set long form options. 635438032Speter Add "MinQueueAge" option to set the minimum time between attempts 635538032Speter to run the queue. For example, if the queue interval 635638032Speter (-q value) is five minutes, but the minimum queue age 635738032Speter is fifteen minutes, jobs won't be tried more often than 635838032Speter once every fifteen minutes. This can be used to give 635938032Speter you more responsiveness if your delivery mode is set to 636038032Speter queue-only. 636138032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 636238032Speter :include: and .forward files. 636338032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 636438032Speter key field name, the value field name, and the field 636538032Speter delimiter. The field delimiter can be a single character 636638032Speter or the sequence "\t" or "\n" for tab or newline. 636738032Speter These are for use by NIS+ and similar access methods. 636838032Speter Change maps to always strip quotes before lookups; the -q flag 636943730Speter turns off this behavior. Suggested by Motonori Nakamura. 637038032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 637138032Speter key and value field names respectively. Code donated by 637238032Speter Sun Microsystems. 637338032Speter Add "hesiod" map class. The "file name" is used as the 637438032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 637538032Speter first value found for the match. Code donated by Scott 637638032Speter Hutton of Indiana University. 637738032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 637838032Speter specify the name of the property that is searched as the 637938032Speter key and a -v flag to specify the name of the property that 638038032Speter is returned as the value (defaults to "members"). The 638138032Speter default map is "/aliases". Some code based on code 638238032Speter contributed by Robert La Ferla of Hot Software. 638338032Speter Add "text" map class. This does slow, linear searches through 638438032Speter text files. The -z flag specifies a column delimiter 638538032Speter (defaults to any sequence of white space), the -k flag 638638032Speter sets the key column number, and the -v flag sets the 638738032Speter value column number. Lines beginning with `#' are treated 638838032Speter as comments. 638938032Speter Add "program" map class to execute arbitrary programs. The search 639038032Speter key is presented as the last argument; the output is one 639138032Speter line read from the programs standard output. Exit statuses 639238032Speter are from sysexits.h. 639338032Speter Add "sequence" map class -- searches maps in sequence until it 639438032Speter finds a match. For example, the declarations: 639538032Speter Kmap1 ... 639638032Speter Kmap2 ... 639738032Speter Kmapseq sequence map1 map2 639838032Speter defines a map "mapseq" that first searches map1; if the 639938032Speter value is found it is returned immediately, otherwise 640038032Speter map2 is searched and the value returned. 640138032Speter Add "switch" map class. This is much like "sequence" except that 640238032Speter the ordering is fetched from an external file, usually 640338032Speter the system service switch. The parameter is the name of 640438032Speter the service to switch on, and the maps that it will use 640538032Speter are the name of the switch map followed by ".service_type". 640638032Speter For example, if the declaration of the map is 640738032Speter Ksample switch hosts 640838032Speter and the system service switch specifies that hosts are 640938032Speter looked up using dns and nis in that order, then this is 641038032Speter equivalent to 641138032Speter Ksample sequence sample.dns sample.nis 641238032Speter The subordinate maps (sample.*) must already be defined. 641338032Speter Add "user" map class -- looks up users using getpwnam. Takes a 641438032Speter "-v field" flag on the definition that tells what passwd 641538032Speter entry to return -- legal values are name, passwd, uid, gid, 641638032Speter gecos, dir, and shell. Generally expected to be used with 641738032Speter the -m (matchonly) flag. 641838032Speter Add "bestmx" map class -- returns the best MX value for the host 641938032Speter listed as the value. If there are several "best" MX records 642038032Speter for this host, one will be chosen at random. 642138032Speter Add "userdb" map class -- looks up entries in the user database. 642238032Speter The "file name" is actually the tag that will be used, 642338032Speter typically "mailname". If there are multiple entries 642438032Speter matching the name, the one chosen is undefined. 642538032Speter Add multiple queue timeouts (both return and warning). These are 642638032Speter set by the Precedence: or Priority: header fields to one of 642738032Speter three values. If a Priority: is set and has value "normal", 642864562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 642938032Speter used. If no priority is set, the Precedence: is consulted; 643038032Speter if negative, non-urgent timeouts are used; if greater than 643138032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 643238032Speter are used. The timeouts are set by setting the six timeouts 643338032Speter queue{warn,return}.{urgent,normal,non-urgent}. 643438032Speter Fix problem when a mail address is resolved to a $#error mailer 643538032Speter with a temporary failure indication; it works in SMTP, 643638032Speter but when delivering locally the mail is silently discarded. 643738032Speter This patch, from Kyle Jones of UUNET, bounces it instead 643838032Speter of queueing it (queueing is very hard). 643938032Speter When using /etc/hosts or NIS-style lookups, don't assume that 644038032Speter the first name in the list is the best one -- instead, 644138032Speter search for the first one with a dot. For example, if 644238032Speter an /etc/hosts entry reads 644338032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 644438032Speter this change will use the second name as the canonical 644538032Speter machine name instead of the initial, unqualified name. 644638032Speter Change dequote map to replace spaces in quoted text with a value 644738032Speter indicated by the -s flag on the dequote map definition. 644838032Speter For example, ``Mdequote dequote -s_'' will change 644938032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 645038032Speter quoted (because of the space character). Suggested by Dan 645138032Speter Oscarsson for use in X.400 addresses. 645238032Speter Implement long macro names as ${name}; long class names can 645338032Speter be similarly referenced as $={name} and $~{name}. 645438032Speter Definitions are (e.g.) ``D{name}value''. Names that have 645538032Speter a leading lower case letter or punctuation characters are 645638032Speter reserved for internal use by sendmail; i.e., config files 645738032Speter should use names that begin with a capital letter. Based 645838032Speter on code contributed by Dan Oscarsson. 645938032Speter Fix core dump if getgrgid returns a null group list (as opposed 646038032Speter to an empty group list, that is, a pointer to a list 646138032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 646238032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 646338032Speter failed, it called syserr which called newstr which called 646438032Speter xalloc.... The newstr is now avoided for "panic" messages. 646538032Speter Reported by Stuart Kemp of James Cook University. 646638032Speter Improve connection cache timeouts; previously, they were not even 646738032Speter checked if you were delivering to anything other than an 646838032Speter IPC-connected host, so a series of (say) local mail 646938032Speter deliveries could cause cached connections to be open 647038032Speter much longer than the specified timeout. 647138032Speter If an incoming message exceeds the maximum message size, stop 647238032Speter writing the incoming bytes to the queue data file, since 647338032Speter this can fill your mqueue partition -- this is a possible 647438032Speter denial-of-service attack. 647538032Speter Don't reject all numeric local user names unless HESIOD is 647638032Speter defined. It turns out that Posix allows all-numeric 647738032Speter user names. Fix from Tony Sanders of BSDI. 647838032Speter Add service switch support. If the local OS has a service 647938032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 648038032Speter on DEC systems) that will be used; otherwise, it falls back 648138032Speter to using a local mechanism based on the ServiceSwitchFile 648238032Speter option (default: /etc/service.switch). For example, if the 648338032Speter service switch lists "files" and "nis" for the aliases 648438032Speter service, that will be the default lookup order. the "files" 648538032Speter ("local" on DEC) service type expands to any alias files 648638032Speter you listed in the configuration file, even if they aren't 648738032Speter actually file lookups. 648838032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 648938032Speter variable which tells whether or not DNS should be considered 649038032Speter canonical. This is now determined based on whether or not 649138032Speter "dns" is in the service list for "hosts". 649238032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 649338032Speter Status Notifications). DSN notifications override 649438032Speter Return-Receipt-To: headers, which are bogus anyhow -- 649538032Speter support for them has been removed. 649638032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 649738032Speter definitions to define the types used in DSN returns for 649838032Speter MTA names, addresses, and diagnostics respectively. 649938032Speter Extend heuristic to force running in ESMTP mode to look for the 650038032Speter five-character string "ESMTP" anywhere in the 220 greeting 650138032Speter message (not just the second line). This is to provide 650238032Speter better compatibility with other ESMTP servers. 650338032Speter Print sequence number of job when running the queue so you can 650438032Speter easily see how much progress you have made. Suggested 650538032Speter by Peter Wemm of DIALix. 650638032Speter Map newlines to spaces in logged message-ids; some versions of 650738032Speter syslog truncate the rest of the line after newlines. 650838032Speter Suggested by Fletcher Mattox of U. Texas. 650938032Speter Move up forking for job runs so that if a message is split into 651038032Speter multiple envelopes you don't get "fork storms" -- this 651138032Speter also improves the connection cache utilization. 651238032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 651338032Speter the purposes of refusing to send error returns. Suggested 651438032Speter by Motonori Nakamura of Ritsumeikan University. 651538032Speter Relax rules on when a file can be written when referenced from 651638032Speter the aliases file: use the default uid/gid instead of the 651738032Speter real uid/gid. This allows you to create a file owned by 651838032Speter and writable only by the default uid/gid that will work 651990792Sgshapiro all the time (without having the set-user-ID bit set). Change 652038032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 652138032Speter Microsystems. 652238032Speter Add "DialDelay" option (no short name) to provide an "extra" 652338032Speter delay for dial on demand systems. If this is non-zero 652438032Speter and a connect fails, sendmail will wait this long and 652538032Speter then try again. If it takes longer than the kernel 652638032Speter timeout interval to establish the connection, this 652738032Speter option can give the network software time to establish 652838032Speter the link. The default units are seconds. 652938032Speter Move logging of sender information to be as early as possible; 653038032Speter previously, it could be delayed a while for SMTP mail 653138032Speter sent to aliases. Suggested by Brad Knowles of the 653238032Speter Defense Information Systems Agency. 653338032Speter Call res_init() before setting RES_DEBUG; this is required by 653438032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 653538032Speter the National Computer Security Center. 653638032Speter Add xdelay= field in logs -- this is a transaction delay, telling 653738032Speter you how long it took to deliver to this address on the 653838032Speter last try. It is intended to be used for sorting mailing 653938032Speter lists to favor "quick" addresses. Provided for use by 654038032Speter the mailprio scripts (see below). 654138032Speter If a map cannot be opened, and that map is non-optional, and 654238032Speter an address requires that map for resolution, queue the 654338032Speter map instead of bouncing it. This involves creating a 654438032Speter pseudo-class of maps called "bogus-map" -- if a required 654538032Speter map cannot be opened, the class is changed to bogus-map; 654638032Speter all queries against bogus-map return "tempfail". The 654738032Speter bogus-map class is not directly accessible. A sample 654838032Speter implementation was donated by Jem Taylor of Glasgow 654938032Speter University Computing Service. 655038032Speter Fix a possible core dump when mailing to a program that talks 655138032Speter SMTP on its standard input. Fix from Keith Moore of 655238032Speter the University of Kentucky. 655338032Speter Make it possible to resolve filenames to $#local $: @ /filename; 655438032Speter previously, the "@" would cause it to not be recognized 655538032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 655638032Speter Accept a -1 signal to re-exec the daemon. This only works if 655738032Speter argv[0] is a full path to sendmail. 655838032Speter Fix bug in "addr=..." field in O option on little-endian machines 655938032Speter -- the network number wasn't being converted to network 656038032Speter byte order. Patch from Kurt Lidl of Pix Technologies 656138032Speter Corporation. 656238032Speter Pre-initialize the resolver early on; this is to avoid a bug with 656338032Speter BIND 4.9.3 that can cause the _res.retry field to get 656438032Speter reset to zero, causing all name server lookups to time 656538032Speter out. Fix from Matt Day of Artisoft. 656638032Speter Restore T line (trusted users) in config file -- but instead of 656738032Speter locking out the -f flag, they just tell whether or not 656838032Speter an X-Authentication-Warning: will be added. This really 656938032Speter just creates new entries in class 't', so "Ft/file/name" 657038032Speter can be used to read trusted user names from a file. 657138032Speter Trusted users are also allowed to execute programs even 657238032Speter if they have a shell that isn't in /etc/shells. 657338032Speter Improve NEWDB alias file rebuilding so it will create them 657438032Speter properly if they do not already exist. This had been 657538032Speter a MAYBENEXTRELEASE feature in 8.6.9. 657638032Speter Check for @:@ entry in NIS maps before starting up to avoid 657738032Speter (but not prevent, sigh) race conditions. This ought to 657838032Speter be handled properly in ypserv, but isn't. Suggested by 657938032Speter Michael Beirne of Motorola. 658038032Speter Refuse connections if there isn't enough space on the filesystem 658138032Speter holding the queue. Contributed by Robert Dana of Wolf 658238032Speter Communications. 658338032Speter Skip checking for directory permissions in the path to a file 658438032Speter when checking for file permissions iff setreuid() 658538032Speter succeeded -- it is unnecessary in that case. This avoids 658638032Speter significant performance problems when looking for .forward 658738032Speter files. Based on a suggestion by Win Bent of USC. 658838032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 658938032Speter arbitrary ruleset number assigned or "Sname = integer" 659038032Speter to assign a specific ruleset number. Reference is 659138032Speter $>name_or_number. Names can be composed of alphas, digits, 659238032Speter underscore, or hyphen (first character must be non-numeric). 659338032Speter Allow -o flag on AliasFile lines to make the alias file optional. 659438032Speter From Bryan Costales of ICSI. 659538032Speter Add NoRecipientAction option to handle the case where there is 659638032Speter no legal recipient header in the message. It can take 659738032Speter on values: 659838032Speter None Leave the message as is. The 659938032Speter message will be passed on even 660038032Speter though it is in technically 660138032Speter illegal syntax. 660238032Speter Add-To Add a To: header with any 660338032Speter recipients that it can find from 660438032Speter the envelope. This risks exposing 660538032Speter Bcc: recipients. 660638032Speter Add-Apparently-To Add an Apparently-To: header. This 660738032Speter has almost no redeeming social value, 660838032Speter and is provided only for back 660938032Speter compatibility. 661038032Speter Add-To-Undisclosed Add a header reading 661138032Speter To: undisclosed-recipients:; 661238032Speter which will have the effect of 661338032Speter making the message legal without 661438032Speter exposing Bcc: recipients. 661538032Speter Add-Bcc To add an empty Bcc: header. 661638032Speter There is a chance that mailers down 661738032Speter the line will delete this header, 661838032Speter which could cause exposure of Bcc: 661938032Speter recipients. 662038032Speter The default is NoRecipientAction=None. 662138032Speter Truncate (rather than delete) Bcc: lines in the header. This 662238032Speter should prevent later sendmails (at least, those that don't 662338032Speter themselves delete Bcc:) from considering this message to 662438032Speter be non-conforming -- although it does imply that non-blind 662538032Speter recipients can see that a Bcc: was sent, albeit not to whom. 662638032Speter Add SafeFileEnvironment option. If declared, files named as delivery 662738032Speter targets must be regular files in addition to the regular 662838032Speter checks. Also, if the option is non-null then it is used as 662938032Speter the name of a directory that is used as a chroot(2) 663038032Speter environment for the delivery; the file names listed in an 663138032Speter alias or forward should include the name of this root. 663238032Speter For example, if you run with 663338032Speter O SafeFileEnvironment=/arch 663438032Speter then aliases should reference "/arch/rest/of/path". If a 663538032Speter value is given, sendmail also won't try to save to 663638032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 663738032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 663838032Speter Support -A flag for alias files; this will comma concatenate like 663938032Speter entries. For example, given the aliases: 664038032Speter list: member1 664138032Speter list: member2 664238032Speter and an alias file declared as: 664338032Speter OAhash:-A /etc/aliases 664438032Speter the final alias inserted will be "list: member1,member2"; 664538032Speter without -A you will get an error on the second and subsequent 664638032Speter alias for "list". Contributed by Bryan Costales of ICSI. 664738032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 664838032Speter Fix a problem that could cause very long addresses to core dump in 664938032Speter some special circumstances. Problem pointed out by Allan 665038032Speter Johannesen. 665138032Speter (Internal change.) Change interface to expand() (macro expansion) 665238032Speter to be simpler and more consistent. 665338032Speter Delete check for funny qf file names. This didn't really give 665438032Speter any extra security and caused some people some problems. 665538032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 665638032Speter at compile time.) Suggested by Kyle Jones of UUNET. 665738032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 665838032Speter merge with DSN code; this is simpler and more consistent. 665938032Speter This may affect some people who have written their own 666038032Speter checkcompat() routine. 666138032Speter (Internal change.) Eliminate `D' line in qf file. The df file 666238032Speter is now assumed to be the same name as the qf file (with 666338032Speter the `q' changed to a `d', of course). 666438032Speter Avoid forking for delivery if all recipient mailers are marked as 666538032Speter "expensive" -- this can be a major cost on some systems. 666638032Speter Essentially, this forces sendmail into "queue only" mode 666738032Speter if all it is going to do is queue anyway. 666838032Speter Avoid sending a null message in some rather unusual circumstances 666938032Speter (specifically, the RCPT command returns a temporary 667038032Speter failure but the connection is lost before the DATA 667138032Speter command). Fix from Scott Hammond of Secure Computing 667238032Speter Corporation. 667338032Speter Change makesendmail to use a somewhat more rational naming scheme: 667438032Speter Makefiles and obj directories are named $os.$rel.$arch, 667538032Speter where $os is the operating system (e.g., SunOS), $rel is 667638032Speter the release number (e.g., 5.3), and $arch is the machine 667738032Speter architecture (e.g., sun4). Any of these can be omitted, 667838032Speter and anything after the first dot in a release number can 667938032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 668038032Speter version used $os.$arch.$rel and was rather less general. 668138032Speter Change makesendmail to do a "make depend" in the target directory 668238032Speter when it is being created. This involves adding an empty 668338032Speter "depend:" entry in most Makefiles. 668438032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 668538032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 668638032Speter of the Finnish Meteorological Institute. 668738032Speter Fix problem that could cause multiple responses to DATA command 668838032Speter on header syntax errors (e.g., lines beginning with colons). 668938032Speter Problem noted by Jens Thomassen of the University of Oslo. 669038032Speter Don't let null bytes in headers cause truncation of the rest of 669138032Speter the header. 669238032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 669338032Speter Increase timeouts on message data puts to allow time for receivers 669438032Speter to canonify addresses in headers on the fly. This is still 669538032Speter a rather ugly heuristic. From Motonori Nakamura. 669638032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 669738032Speter records are not used when canonifying names, and when MX 669838032Speter lookups are done for addressing they must be fully 669938032Speter qualified. This is useful if you have a wildcard MX record, 670038032Speter although it may cause other problems. In general, don't use 670138032Speter wildcard MX records. Patch from Motonori Nakamura. 670238032Speter Eliminate default two-line SMTP greeting message. Instead of 670338032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 670438032Speter is added between the first and second word of the first 670538032Speter line of the greeting message (i.e., immediately after the 670638032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 670738032Speter compile flag. Old sendmails won't see the ESMTP, but that's 670838032Speter acceptable because SIZE was the only useful extension that 670938032Speter old sendmails understand. 671038032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 671138032Speter invoked state dumps. From Masaharu Onishi. 671238032Speter Allow on-line comments in .forward and :include: files; they are 671338032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 671438032Speter is a space or a tab. This is intended for native 671538032Speter representation of non-ASCII sets such as Japanese, where 671638032Speter existing encodings would be unreadable or would lose 671738032Speter data -- for example, 671838032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 671938032Speter (romanized/less information) 672038032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 672138032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 672238032Speter (with MIME encoding, not human readable) 672338032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 672438032Speter (native encoding with ISO-2022-JP) 672538032Speter The last form is human readable in the Japanese environment. 672638032Speter Based on a fix from (surprise!) Motonori Nakamura. 672738032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 672838032Speter messages to that host; these are most frequently associated 672938032Speter with addresses rather than the host, with the exception of 673038032Speter 421 (service shutting down). The effect was to cause queues 673138032Speter to sometimes take an excessive time to flush. Reported by 673238032Speter Robert Sargent of Southern Geographics Technologies and 673338032Speter Eric Prestemon of American University. 673438032Speter Add Nice=N mailer option to set the niceness at which a mailer will 673538032Speter run. This is actually a relative niceness (that is, an 673638032Speter increment on the background value). 673738032Speter Log queue runs that are skipped due to high loads. They are logged 673838032Speter at LOG_INFO priority iff the log level is > 8. Contributed 673938032Speter by Bruce Nagel of Data General. 674038032Speter Allow the error mailer to accept a DSN-style error status code 674138032Speter instead of an sysexits status code in the host part. 674238032Speter Anything with a dot will be interpreted as a DSN-style code. 674338032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 674438032Speter to encode characters that might be munged by an EBCDIC system 674538032Speter in addition to the set required by RFC 1521. The additional 674638032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 674738032Speter (Think of "IBM 360" as the mnemonic for this flag.) 674838032Speter Change check for mailing to files to look for a pathname of [FILE] 674938032Speter rather than looking for the mailer named *file*. The mapping 675038032Speter of leading slashes still goes to the *file* mailer. This 675138032Speter allows you to implement the *file* mailer as a separate 675238032Speter program, for example, to insert a Content-Length: header 675338032Speter or do special security policy. However, note that the usual 675438032Speter initial checking for the file permissions is still done, and 675538032Speter the program in question needs to be very careful about how 675638032Speter it does the file write to avoid security problems. 675738032Speter Be able to read ~root/.forward even if the path isn't accessible to 675838032Speter regular users. This is disrecommended because sendmail 675938032Speter sometimes does not run as root (e.g., when an unsafe option 676038032Speter is specified on the command line), but should otherwise be 676138032Speter safe because .forward files must be owned by the user for 676238032Speter whom mail is being forwarded, and cannot be a symbolic link. 676338032Speter Suggested by Forrest Aldrich of Wang Laboratories. 676438032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 676538032Speter file. This is used for canonifying hostnames when the 676638032Speter service type is "files". 676738032Speter Implement programs on F (read class from file) line. The syntax is 676838032Speter Fc|/path/to/program to read the output from the program 676938032Speter into class "c". 677038032Speter Probe the network interfaces to find alternate names for this 677138032Speter host. Requires the SIOCGIFCONF ioctl call. Code 677238032Speter contributed by SunSoft. 677338032Speter Add "E" configuration line to set or propagate environment 677438032Speter variables into children. "E<envar>" will propagate 677538032Speter the named variable from the environment when sendmail 677638032Speter was invoked into any children it calls; "E<envar>=<value>" 677738032Speter sets the named variable to the indicated value. Any 677838032Speter variables not explicitly named will not be in the child 677938032Speter environment. However, sendmail still forces an 678038032Speter "AGENT=sendmail" environment variable, in part to enforce 678138032Speter at least one environment variable, since many programs and 678238032Speter libraries die horribly if this is not guaranteed. 678338032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 678438032Speter alias databases -- new algorithm looks for the substring 678538032Speter "/yp/" in the file name. This is more portable and involves 678638032Speter less overhead. Suggested by Motonori Nakamura. 678738032Speter Dynamically allocate the queue work list so that you don't lose 678838032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 678938032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 679038032Speter should not need to be changed) and the MaxQueueRunSize option, 679138032Speter which is the absolute maximum number of jobs that will ever 679238032Speter be handled in a single queue run. Based on code contributed 679338032Speter by Brian Coan of the Institute for Global Communications. 679438032Speter Log message when a message is dropped because it exceeds the maximum 679538032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 679638032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 679738032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 679838032Speter of Mark G. Thomas Consulting. 679938032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 680038032Speter OS-dependent defines). The old semantic of -d0.1 to not 680138032Speter run the daemon in background has been moved to -d99.100, 680238032Speter and the old 52.5 flag (to avoid disconnect() from closing 680338032Speter all output files) has been moved to 52.100. This makes 680438032Speter things more consistent (flags below .100 don't change 680538032Speter semantics) and separates out the backgrounding so that 680638032Speter it doesn't happen automatically on other unrelated debugging 680738032Speter flags. 680838032Speter If -t is used but no addresses are found in the header, give an 680938032Speter error message rather than just doing nothing. Fix from 681038032Speter Motonori Nakamura. 681138032Speter On systems (like SunOS) where the effective gid is not necessarily 681238032Speter included in the group list returned by getgroups(), the 681338032Speter `restrictmailq' option could sometimes cause an authorized 681438032Speter user to not be able to use `mailq'. Fix from Charles Hannum 681538032Speter of MIT. 681638032Speter Allow symbolic service names for [IPC] mailers. Suggested by 681738032Speter Gerry Magennis of Logica International. 681838032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 681938032Speter when running DNS. For example, if the name FTP.Foo.ORG is 682038032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 682138032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 682238032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 682338032Speter This is technically illegal under RFC 822 and 1123, but the 682438032Speter IETF is moving toward legalizing it. Note that turning on 682538032Speter this option is not sufficient to guarantee that a downstream 682638032Speter neighbor won't rewrite the address for you. 682738032Speter Add "-m" flag to makesendmail script -- this tells you what object 682838032Speter directory and Makefile it will use, but doesn't actually do 682938032Speter the make. 683038032Speter Do some additional checking on the contents of the qf file to try 683138032Speter to detect attacks against the qf file. In particular, 683238032Speter abort on any line beginning "From ", and add an "end of 683338032Speter file" line -- any data after that line is prohibited. 683438032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 683538032Speter choices. This can be overridden in the Makefile by using 683638032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 683738032Speter (to the extent that we know it) or by defining 683838032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 683938032Speter sendmail 8 to have more consistent installation instructions. 684038032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 684138032Speter of Sun Microsystems. 684238032Speter Improved symbol table hash function from Eric Wassenaar. This one 684338032Speter is at least 50% faster. 684438032Speter Fix problem that didn't notice that timeout on file open was a 684538032Speter transient error. Fix from Larry Parmelee of Cornell 684638032Speter University. 684738032Speter Allow comments (lines beginning with a `#') in files read for 684838032Speter classes. Suggested by Motonori Nakamura. 684938032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 685038032Speter of dropping out entirely. This makes testing some of the 685138032Speter name server lookups easier to deal with when there are 685238032Speter hung servers. From Motonori Nakamura. 685338032Speter Add new ${opMode} macro that is set to the current operation mode 685438032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 685538032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 685638032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 685738032Speter Kind of like queue-only mode (Odq) except it tries to avoid 685838032Speter any external service requests; for dial-on-demand hosts that 685938032Speter want to minimize DNS lookups when mail is being queued. For 686038032Speter this to work you will also have to make sure that gethostbyname 686138032Speter of your local host name does not do a DNS lookup. 686238032Speter Improved handling of "out of space" conditions from John Myers of 686338032Speter Carnegie Mellon. 686438032Speter Improved security for mailing to files on systems that have fchmod(2) 686538032Speter support. 686638032Speter Improve "cannot send message for N days" message -- now says "could 686738032Speter not send for past N days". Suggested by Tom Moore of AT&T 686838032Speter Global Information Solutions. 686938032Speter Less misleading Subject: line on messages sent to postmaster only. 687038032Speter From Motonori Nakamura. 687138032Speter Avoid duplicate error messages on bad command line flags. From 687238032Speter Motonori Nakamura. 687338032Speter Better error message for case where ruleset 0 falls off the end 687438032Speter or otherwise does not resolve to a canonical triple. 687538032Speter Fix a problem that could cause multiple bounce messages if a bad 687638032Speter address was sent along with a good address to an SMTP 687738032Speter site where that SMTP site returned a 4yz code in response 687838032Speter to the final dot of the data. Problem reported by David 687938032Speter James of British Telecom. 688038032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 688138032Speter from Alexander Dupuy of System Management ARTS. 688238032Speter Delete duplicates in MX lists -- believe it or not, there are sites 688338032Speter that list the same host twice in an MX list. This deletion 688438032Speter only works on adjacent preferences, so an MX list that 688538032Speter had A=5, B=10, A=15 would leave both As, but one that had 688638032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 688738032Speter just in case there is something weird I haven't thought of. 688838032Speter Suggested by Barry Shein of Software Tool & Die. 688938032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 698438032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 698538032Speter University of Brno (Czech Republic). 698638032Speter KSR OS 1.2.2 support from Todd Miller of the University 698738032Speter of Colorado. 698838032Speter UX4800 support from Kazuhisa Shimizu of NEC. 698938032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 699038032Speter in type ``btree'' maps. The semantics of this are undefined 699138032Speter for regular maps, but it can be useful for the user database. 699238032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 699338032Speter lookups while the rebuild is going on. There is a race 699438032Speter condition between the open(... O_TRUNC ...) and the lock 699538032Speter on the file, but it should be quite small. 699638032Speter SMRSH: sendmail restricted shell added to the release. This can 699738032Speter be used as an alternative to /bin/sh for the "prog" mailer, 699838032Speter giving the local administrator more control over what 699938032Speter programs can be run from sendmail. 700038032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 700138032Speter part of the release proper, and isn't fully supported; in 700238032Speter particular, it does not run on System V based systems and 700338032Speter never will. 700438032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 700538032Speter to allow rmail to compile on systems that don't have 700638032Speter function prototypes and systems that don't have snprintf. 700738032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 700838032Speter lists by transaction delay times so that addresses that 700938032Speter respond quickly get sent first. This is to prevent very 701038032Speter sluggish servers from delaying other peoples' mail. 701138032Speter Contributed by Tony Sanders of BSDI. 701238032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 701338032Speter of BSDI. This has a lot of comments to help people out. 701438032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 701538032Speter put this on the m4 command line. On GNU m4 (which 701638032Speter supports the __file__ primitive) you can run m4 in an 701738032Speter arbitrary directory -- use either: 701838032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 701938032Speter or 702038032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 702138032Speter On other versions of m4 that don't support __file__, you 702238032Speter can use: 702338032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 702438032Speter (Note the trailing slash on the _CF_DIR_ definition.) 702538032Speter Old versions of m4 will default to _CF_DIR_=.. for back 702638032Speter compatibility. 702738032Speter CONFIG: fix mail from <> so it will properly convert to 702838032Speter MAILER-DAEMON on local addresses. 702938032Speter CONFIG: fix code that was supposed to catch colons in host 703038032Speter names. Problem noted by John Gardiner Myers of CMU. 703138032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 703238032Speter From Paul Riddle of the University of Maryland, Baltimore 703338032Speter County. 703438032Speter CONFIG: Catch and reject "." as a host address. 703538032Speter CONFIG: Generalize domaintable to look up all domains, not 703638032Speter just unqualified ones. 703738032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 703838032Speter was never used and didn't work anyway. 703938032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 704038032Speter and d on all mailers in the UUCP class. 704138032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 704238032Speter look for an alias for "user+detail", then for "user+*", and 704338032Speter finally for "user". This is intended for forwarding mail 704438032Speter for system aliases such as root and postmaster to a 704538032Speter centralized hub. 704638032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 704738032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 704838032Speter The F=8 flag is also set on the "relay" mailer, since 704938032Speter this is expected to be another sendmail. 705038032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 705138032Speter the name of the UUCP_RELAY -- in some cases, this is the 705238032Speter wrong value (e.g., when we have local UUCP connections), 705338032Speter and this can create unreplyable addresses. From Chip 705438032Speter Rosenthal of Unicom. 705538032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 705664562Sgshapiro Received: header inserted into all messages. Suggested by 705738032Speter Gary Mills of the University of Manitoba. 705838032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 705943730Speter to get the old behavior. I did this upon observing 706038032Speter that almost everyone needed this feature, and that the 706138032Speter concept I was trying to make happen didn't work with 706238032Speter some user agents anyway. FEATURE(notsticky) still works, 706338032Speter but it is a no-op. 706438032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 706538032Speter names are sent, rather than immediately diagnosing them 706638032Speter as User Unknown. 706738032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 706838032Speter and RELAY_MAILER_ARGS to set the arguments for the 706938032Speter indicated mailers. All default to "IPC $h". Patch from 707038032Speter Larry Parmelee of Cornell University. 707138032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 707238032Speter on the client side" and F=P to get an appropriate 707338032Speter return-path. From Kimmo Suominen. 707438032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 707538032Speter as the local mailer. For addresses of the form "user+detail" 707638032Speter the "detail" part is passed to procmail via the -a flag. 707738032Speter Contributed by Kimmo Suominen. 707838032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 707938032Speter use from mailertables. This lets you execute arbitrary 708038032Speter procmail scripts. Contributed by Kimmo Suominen. 708138032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 708238032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 708338032Speter Paul Southworth of CICNet Systems Support. 708438032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 708538032Speter This causes the null return path to be rewritten as 708638032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 708738032Speter From Michael Hohmuth of Technische Universitat Dresden. 708838032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 708938032Speter list us as the best possible MX record to be treated as 709038032Speter though they were local (essentially, assume that they 709138032Speter are included in $=w). This can cause additional DNS 709238032Speter traffic, but is easier to administer if this fits your 709338032Speter local model. It does not work reliably if there are 709438032Speter multiple hosts that share the best MX preference. 709538032Speter Code contributed by John Oleynick of Rutgers. 709638032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 709738032Speter SHell) instead of /bin/sh as the program used for delivery 709838032Speter to programs. If an argument is included, it is used as 709938032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 710038032Speter assumed. 710138032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 710238032Speter size of messages to the local and procmail mailers 710338032Speter respectively. Contributed by Brad Knowles of the Defense 710438032Speter Information Systems Agency. 710538032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 710638032Speter (just like text outside of angle brackets) in order to 710738032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 710838032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 710938032Speter any real systems any more) and tweak the DOMAIN macro 711038032Speter so that it is less likely that users will accidentally use 711138032Speter the Berkeley defaults. Also, create some generic files 711238032Speter that really can be used in the real world. 711338032Speter CONFIG: Add new configuration macros to set character sets for 711438032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 711538032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 711638032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 711738032Speter The old name will still be accepted for a while at least. 711838032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 711938032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 712038032Speter As with all relays, it can be ``mailer:hostname''. Suggested 712138032Speter by Scott Hutton. 712238032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 712338032Speter by Barb Dijker of Labyrinth Computer Services. 712438032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 712538032Speter performance for large alias files, and this confused many 712638032Speter people. 712738032Speter CONFIG: Add confCF_VERSION to append local information to the 712838032Speter configuration version number displayed during SMTP startup. 712938032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 713038032Speter would only work when locally addressed. Fix from 713138032Speter Edvard Tuinder of Cistron Internet Services. 713238032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 713343730Speter "n" (CheckAliases) is set when rebuilding alias database. 713438032Speter Based on code contributed by Claude Marinier. 713538032Speter CONFIG: Allow mailertable to have values of the form 713638032Speter ``error:code message''. The ``code'' is a status code 713738032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 713838032Speter Contributed by David James <dwj@agw.bt.co.uk>. 713938032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 714038032Speter sender domains that will be replaced with the masquerade name. 714138032Speter These domains will not be treated as local, but if mail passes 714238032Speter through with sender addresses in those domains they will be 714338032Speter replaced by the masquerade name. These can also be specified 714438032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 714538032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 714638032Speter as well as the header. Substantial improvements to this 714738032Speter code were contributed by Per Hedeland. 714838032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 714938032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 715038032Speter by Kimmo Suominen. 715138032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 715238032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 715338032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 715438032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 715538032Speter UUCP addressing.

This caused UnixWare 729838032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 729938032Speter Novell Labs Europe. 730038032Speter Fix problem with static linking of local getopt routine when 730138032Speter using GNU's ld command. Fix from John Kennedy of 730238032Speter Cal State Chico. 730338032Speter It was possible to turn off privacy flags. Problem noted by 730438032Speter *Hobbit*. 730538032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 730638032Speter and Liudvikas Bukys. 730738032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 730838032Speter from Spider Boardman. 730938032Speter CONFIG: No changes (version number only, to keep it in sync 731038032Speter with the binaries). 731138032Speter 731264562Sgshapiro8.6.10/8.6.10 1995/02/10 731338032Speter SECURITY: Diagnose bogus values to some command line flags that 731438032Speter could allow trash to get into headers and qf files. 731538032Speter Validate the name of the user returned by the IDENT protocol. 731638032Speter Some systems that really dislike IDENT send intentionally 731738032Speter bogus information. Problem pointed out by Michael Bushnell 731838032Speter of the Free Software Foundation. Has some security 731938032Speter implications. 732038032Speter Fix a problem causing error messages about DNS problems when 732138032Speter the host name contained a percent sign to act oddly 732238032Speter because it was passed as a printf-style format string. 732338032Speter In some cases this could cause core dumps. 732438032Speter Avoid possible buffer overrun in returntosender() if error 732538032Speter message is quite long. From Fletcher Mattox of the 732638032Speter University of Texas. 732738032Speter Fix a problem that would silently drop "too many hops" error 732838032Speter messages if and only if you were sending to an alias. 732938032Speter From Jon Giltner of the University of Colorado and 733038032Speter Dan Harton of Oak Ridge National Laboratory. 733138032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 733238032Speter set and e->e_message was null. Fix from Bruce Nagel of 733338032Speter Data General. 733438032Speter Fix problem that can still cause df files to be left around 733538032Speter after "hop count exceeded" messages. Fix from Andrew 733638032Speter Chang and Shau-Ping Lo of SunSoft. 733738032Speter Fix a problem that can cause buffer overflows on very long 733838032Speter user names (as might occur if you piped to a program 733938032Speter with a lot of arguments). 734038032Speter Avoid returning an error and re-queueing if the host signature 734138032Speter is null; this can occur on addresses like ``user@.''. 734238032Speter Problem noted by Wesley Craig and the University of 734338032Speter Michigan. 734438032Speter Avoid possible calls to malloc(0) if MCI caching is turned 734538032Speter off. Bug fix from Pierre David of the Laboratoire 734638032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 734738032Speter Universite de Versailles - St Quentin, and Jacky 734838032Speter Thibault. 734938032Speter Make a local copy of the line being sent via senttolist() -- in 735038032Speter some cases, buffers could get trashed by map lookups 735138032Speter causing it to do unexpected things. This also simplifies 735238032Speter some of the map code. 735338032Speter CONFIG: No changes (version number only, to keep it in sync 735438032Speter with the binaries). 735538032Speter 735664562Sgshapiro8.6.9/8.6.9 1994/04/19 735738032Speter Do all mail delivery completely disconnected from any terminal. 735838032Speter This provides consistency with daemon delivery and 735938032Speter may have some security implications. 736038032Speter Make sure that malloc doesn't get called with zero size, 736138032Speter since that fails on some systems. Reported by Ed 736238032Speter Hill of the University of Iowa. 736338032Speter Fix multi-line values for $e (SMTP greeting message). Reported 736438032Speter by Mike O'Connor of Ford Motor Company. 736538032Speter Avoid syserr if no NIS domain name is defined, but the map it 736638032Speter is trying to open is optional. From Win Bent of USC. 736738032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 736838032Speter Hesiod support for UDB from Todd Miller of the University of 736938032Speter Colorado. Use "hesiod" as the service name in the U 737038032Speter option. 737138032Speter Fix a problem that failed to set the "authentic" host name (that 737238032Speter is, the one derived from the socket info) if you called 737338032Speter sendmail -bs from inetd. Based on code contributed by 737438032Speter Todd Miller (this problem was also reported by Guy Helmer 737538032Speter of Dakota State University). This also fixes a related 737638032Speter problem reported by Liudvikas Bukys of the University of 737738032Speter Rochester. 737838032Speter Parameterize "nroff -h" in all the Makefiles so people with 737938032Speter variant versions can use them easily. Suggested by 738038032Speter Peter Collinson of Hillside Systems. 738138032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 738238032Speter spaces between parameters instead of one. Reported by 738338032Speter Valdis Kletnieks of Virginia Tech. 738438032Speter Reduce the number of system calls during message collection by 738538032Speter using global timeouts around the collect() loop. This 738638032Speter code was contributed by Eric Wassenaar. 738738032Speter If the initial hostname name gathering results in a name 738838032Speter without a dot (usually caused by NIS misconfiguration) 738938032Speter and BIND is compiled in, directly access DNS to get 739038032Speter the canonical name. This should make life easier for 739138032Speter Solaris systems. If it still can't be resolved, and 739238032Speter if the name server is listed as "required", try again 739338032Speter in 30 seconds. If that also fails, exit immediately to 739438032Speter avoid bogus "config error: mail loops back to myself" 739538032Speter messages. 739638032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 739738032Speter message to explain how much space was available and 739838032Speter sound a bit less threatening. Suggested by Stan Janet 739938032Speter of the National Institute of Standards and Technology. 740038032Speter If mail is delivered to an alias that has an owner, deliver any 740138032Speter requested return-receipt immediately, and strip the 740238032Speter Return-Receipt-To: header from the subsequent message. 740338032Speter This prevents a certain class of denial of service 740438032Speter attack, arguably gives more reasonable semantics, and 740538032Speter moves things more towards what will probably become a 740638032Speter network standard. Suggested by Christopher Davis of 740738032Speter Kapor Enterprises. 740838032Speter Add a "noreceipts" privacy flag to turn off all return receipts 740938032Speter without recompiling. 741038032Speter Avoid printing ESMTP parameters as part of the error message 741138032Speter if there are errors during parsing. This change is 741238032Speter purely cosmetic. 741338032Speter Avoid sending out error messages during the collect phase of 741438032Speter SMTP; there is an MVS mailer from UCLA that gets 741538032Speter confused by this. Of course, I think it's their bug.... 741638032Speter Check for the $j macro getting undefined, losing a dot, or getting 741738032Speter lost from $=w in the daemon before accepting a connection; 741838032Speter if it is, it dumps state, prints a LOG_ALERT message, 741938032Speter and drops core for debugging. This is an attempt to 742038032Speter track down a bug that I thought was long since gone. 742138032Speter If you see this, please forward the log fragment to 742238032Speter sendmail@sendmail.ORG. 742338032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 742438032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 742538032Speter Wolfhugel. 742638032Speter Instead of trying to truncate the listen queue for the server 742738032Speter SMTP port when the load average is too high, just close 742838032Speter the port completely and reopen it later as needed. 742938032Speter This ensures that the other end gets a quick "connection 743038032Speter refused" response, and that the connection can be 743138032Speter recovered later. In particular, some socket emulations 743238032Speter seem to get confused if you tweak the listen queue 743338032Speter size around and can never start listening to connections 743438032Speter again. The down side is that someone could start up 743538032Speter another daemon process in the interim, so you could 743638032Speter have multiple daemons all not listening to connections; 743738032Speter this could in turn cause the sendmail.pid file to be 743838032Speter incorrect. A better approach might be to accept the 743938032Speter connection and give a 421 code, but that could break 744043730Speter other mailers in mysterious ways and have paging behavior 744138032Speter implications. 744238032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 744338032Speter set debugging on the wrong socket. From Eric Wassenaar. 744438032Speter When creating a df* temporary file, be sure you truncate any 744538032Speter existing data in the file -- otherwise system crashes 744638032Speter and the like could result in extra data being sent. 744738032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 744838032Speter doc directory. This includes some additional 744938032Speter information. 745038032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 745138032Speter of recipient envelope addresses. This should have been 745238032Speter handled by the $&h trick, but broke if people were 745338032Speter mixing domainized and UUCP addresses. They should 745438032Speter probably have converted all the way over to uucp-uudom 745538032Speter instead of uucp-{new,old}, but the failure mode was to 745638032Speter loop the mail, which was bad news. 745738032Speter Portability fixes: 745838032Speter Newer BSDI systems (several people). 745938032Speter Older BSDI systems from Christophe Wolfhugel. 746038032Speter Intergraph CLIX, from Paul Southworth of CICNet. 746138032Speter UnixWare, from Evan Champion. 746238032Speter NetBSD from Adam Glass. 746338032Speter Solaris from Quentin Campbell of the University of 746438032Speter Newcastle upon Tyne. 746538032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 746638032Speter Corporation. 746738032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 746838032Speter SunOS (it has setsid() and setvbuf() calls) from 746938032Speter Jonathan Kamens of OpenVision Technologies. 747038032Speter HP-UX from Tor Lillqvist. 747138032Speter New Files: 747238032Speter src/Makefile.CLIX 747338032Speter src/Makefile.NCR3000 747438032Speter doc/changes/Makefile 747538032Speter doc/changes/changes.me 747638032Speter doc/changes/changes.ps 747738032Speter 747864562Sgshapiro8.6.8/8.6.6 1994/03/21 747938032Speter SECURITY: it was possible to read any file as root using the 748038032Speter E (error message) option. Reported by Richard Jones; 748138032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 748238032Speter 748364562Sgshapiro8.6.7/8.6.6 1994/03/14 748438032Speter SECURITY: it was possible to get root access by using weird 748538032Speter values to the -d flag. Thanks to Alain Durand of 748638032Speter INRIA for forwarding me the notice from the bugtraq 748738032Speter list. 748838032Speter 748964562Sgshapiro8.6.6/8.6.6 1994/03/13 749038032Speter SECURITY: the ability to give files away on System V-based 749138032Speter systems proved dangerous -- don't run as the owner 749238032Speter of a :include: file on a system that allows giveaways. 749338032Speter Unfortunately, this also applies to determining a 749438032Speter valid shell. 749538032Speter IMPORTANT: Previous versions weren't expiring old connections 749638032Speter in the connection cache for a long time under some 749738032Speter circumstances. This could result in resource exhaustion, 749838032Speter both at your end and at the other end. This checks the 749938032Speter connections for timeouts much more frequently. From 750038032Speter Doug Anderson of NCSC. 750138032Speter Fix a glitch that snuck in that caused programs to be run as 750238032Speter the sender instead of the recipient if the mail was 750338032Speter from a local user to another local user. From 750438032Speter Motonori Nakamura of Kyoto University. 750538032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 750638032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 750738032Speter Bryan Costales of ICSI. 750838032Speter Change the method used to declare the "statfs" availability; 750938032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 751038032Speter tweaking in conf.c, there is a single #define called 751138032Speter SFS_TYPE which takes on one of six values (SFS_NONE 751238032Speter for no statfs availability, SFS_USTAT for the ustat(2) 751338032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 751438032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 751538032Speter statfs(2) call with the declarations in <sys/vfs.h>, 751638032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 751738032Speter Fix glitch in NetInfo support that could return garbage if 751838032Speter there was no "/locations/sendmail" property. From 751938032Speter David Meyer of the University of Virginia. 752038032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 752138032Speter to allow Linux to turn it off even though it is a 752238032Speter BSD-like system. 752338032Speter Allow setting of "ident" timeout to zero to turn off the ident 752438032Speter protocol entirely. 752538032Speter Make 7-bit stripping local to a connection (instead of to a 752638032Speter mailer); this allows you to specify that SMTP is a 752738032Speter 7-bit channel, but revert to 8-bit should it advertise 752838032Speter that it supports 8BITMIME. You still have to specify 752938032Speter mailer flag 7 to get this stripping at all. 753038032Speter Improve makesendmail script so it handles more cases automatically. 753138032Speter Tighten up restrictions on taking ownership of :include: files 753238032Speter to avoid problems on systems that allow you to give away 753338032Speter files. 753438032Speter Fix a problem that made it impossible to rebuild the alias 753538032Speter file if it was on a read-only file system. From 753638032Speter Harry Edmon of the University of Washington. 753738032Speter Improve MX randomization function. From John Gardiner Myers 753838032Speter of CMU. 753938032Speter Fix a minor glitch causing a bogus message to be printed (used 754038032Speter %s instead of %d in a printf string for the line number) 754138032Speter when a bad queue file was read. From Harry Edmon. 754238032Speter Allow $s to remain NULL on locally generated mail. I'm not 754338032Speter sure this is necessary, but a lot of people have complained 754438032Speter about it, and there is a legitimate question as to whether 754538032Speter "localhost" is legal as an 822-style domain. 754638032Speter Fix a problem with very short line lengths (mailer L= flag) in 754738032Speter headers. This causes a leading space to be added onto 754838032Speter continuation lines (including in the body!), and also 754938032Speter tries to wrap headers containing addresses (From:, To:, 755038032Speter etc) intelligently at the shorter line lengths. Problem 755138032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 755238032Speter Log the real user name when logging syserrs, since these can have 755338032Speter security implications. Suggested by several people. 755438032Speter Fix address logging of cached connections -- it used to always 755538032Speter log the numeric address as zero. This is a somewhat 755638032Speter bogus implementation in that it does an extra system 755738032Speter call, but it should be an inexpensive one. Fix from 755838032Speter Motonori Nakamura. 755938032Speter Tighten up handling of short syslog buffers even more -- there 756038032Speter were cases where the outgoing relay= name was too long 756138032Speter to share a line with delay= and mailer= logging. 756238032Speter Limit the overhead on split envelopes to one open file descriptor 756338032Speter per envelope -- previously the overhead was three 756438032Speter descriptors. This was in response to a problem reported 756538032Speter by P{r (Pell) Emanuelsson. 756638032Speter Fixes to better handle the case of unexpected connection closes; 756738032Speter this redirects the output to the transcript so the info 756838032Speter is not lost. From Eric Wassenaar. 756938032Speter Fix potential string overrun if you macro evaluate a string that 757038032Speter has a naked $ at the end. Problem noted by James Matheson 757138032Speter <jmrm@eng.cam.ac.uk>. 757238032Speter Make default error number on $#error messages 553 (``Requested 757338032Speter action not taken: mailbox name not allowed'') instead of 757438032Speter 501 (``Syntax error in parameters or arguments'') to 757538032Speter avoid bogus "protocol error" messages. 757638032Speter Strip off any existing trailing dot on names during $[ ... $] 757738032Speter lookup. This prevents it from ending up with two dots 757838032Speter on the end of dot terminated names. From Wesley Craig 757938032Speter of the University of Michigan and Bryan Costales of ICSI. 758038032Speter Clean up file class reading so that the debugging information is 758138032Speter more informative. It hadn't been using setclass, so you 758238032Speter didn't see the class items being added. 758338032Speter Avoid core dump if you are running a version of sendmail where 758438032Speter NIS is compiled in, and you specify an NIS map, but 758538032Speter NIS is not running. Fix from John Oleynick of 758638032Speter Rutgers. 758738032Speter Diagnose bizarre case where res_search returns a failure value, 758838032Speter but sets h_errno to a success value. 758938032Speter Make sure that "too many hops" messages are considered important 759038032Speter enough to send an error to the Postmaster (that is, the 759138032Speter address specified in the P option). This fix should 759238032Speter help problems that cause the df file to be left around 759338032Speter sometimes -- unfortunately, I can't seem to reproduce 759438032Speter the problem myself. 759538032Speter Avoid core dump (null pointer reference) on EXPN command; this 759638032Speter only occurred if your log level was set to 10 or higher 759738032Speter and the target account was an alias or had a .forward file. 759838032Speter Problem noted by Janne Himanka. 759938032Speter Avoid "denial of service" attacks by someone who is flooding your 760038032Speter SMTP port with bad commands by shutting the connection 760138032Speter after 25 bad commands are issued. From Kyle Jones of 760238032Speter UUNET. 760338032Speter Fix core dump on error messages with very long "to" buffers; 760438032Speter fmtmsg overflows the message buffer. Fixed by trimming 760538032Speter the to address to 203 characters. Problem reported by 760638032Speter John Oleynick. 760738032Speter Fix configuration for HASFLOCK -- there were some spots where 760838032Speter a #ifndef was incorrectly #ifdef. Pointed out by 760938032Speter George Baltz of the University of Maryland. 761038032Speter Fix a typo in savemail() that could cause the error message To: 761138032Speter lists to be incorrect in some places. From Motonori 761238032Speter Nakamura. 761338032Speter Fix a glitch that can cause duplicate error messages on split 761438032Speter envelopes where an address on one of the lists has a 761538032Speter name server failure. Fix from Voradesh Yenbut of the 761638032Speter University of Washington. 761738032Speter Fix possible bogus pointer reference on ESMTP parameters that 761838032Speter don't have an ``=value'' part. 761938032Speter CNAME loops caused an error message to be generated, but also 762038032Speter re-queued the message. Changed to just re-queue the 762138032Speter message (it's really hard to just bounce it because 762238032Speter of the weird way the name server works in the presence 762338032Speter of CNAME loops). Problem noted by James M.R.Matheson 762438032Speter of Cambridge University. 762538032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 762638032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 762738032Speter user name. Suggested by Andreas Stolcke of ICSI. 762838032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 762938032Speter override it easily in the Makefile -- that is, you can 763038032Speter turn it off using -DNAMED_BIND=0. 763138032Speter If a gethostbyname(...) of an address with a trailing dot fails, 763238032Speter try it without the trailing dot. This is because if 763338032Speter you have a version of gethostbyname() that falls back 763438032Speter to NIS or the /etc/hosts file it will fail to find 763538032Speter perfectly reasonable names that just don't happen to 763638032Speter be dot terminated in the hosts file. You don't want to 763738032Speter strip the dot first though because we're trying to ensure 763838032Speter that country names that match one of your subdomains get 763938032Speter a chance. 764038032Speter PRALIASES: fix bogus output on non-null-terminated strings. 764138032Speter From Bill Gianopoulos of Raytheon. 764238032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 764338032Speter This was in code intended to only catch the self-literal 764438032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 764538032Speter IP address), but the code was broken. However, it will 764638032Speter still do this if $M is defined; this is necessary to 764738032Speter get client configurations to work (sigh). Note that this 764838032Speter means that $M overrides :mailname entries in the user 764938032Speter database! Problem noted by Paul Southworth. 765038032Speter CONFIG: Fix definition of Solaris help file location. From 765138032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 765238032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 765338032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 765438032Speter and USENET_MAILER_MAX to tweak the maximum message 765538032Speter size for various mailers. 765638032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 765738032Speter instead of assuming that it is "inews" for consistency 765838032Speter with other mailers. From Michael Corrigan of UC San Diego. 765938032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 766038032Speter qualify the address in the SMTP envelope as user@{relay|hub} 766138032Speter instead of user@$j. From Bill Wisner of The Well. 766238032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 766338032Speter CONFIG: Don't turn off case mapping of user names in the local 766438032Speter mailer for IRIX. This was different than most every other 766538032Speter system. 766638032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 766738032Speter envelope. Noted by Thierry Besancon 766838032Speter <besancon@excalibur.ens.fr>. 766938032Speter CONFIG: Don't include -z by default on uux line -- most systems 767038032Speter don't want it set by default. Pointed out by Philippe 767138032Speter Michel of Thomson CSF. 767238032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 767338032Speter host name was foo.bar.ray.com and you matched against 767438032Speter ".ray.com", the old implementation bound %1 to "bar" 767538032Speter instead of "foo.bar". Also, allow "." in the mailertable 767638032Speter to match anything -- essentially, take over SMART_HOST. 767738032Speter This also moves matching of explicit local host names 767838032Speter before the mailertable so they don't have to be special 767938032Speter cased in the mailertable data. Reported by Bill 768038032Speter Gianopoulos of Raytheon; the fix for the %1 binding 768138032Speter problem was contributed by Nicholas Comanos of the 768238032Speter University of Sydney. 768338032Speter CONFIG: Don't include "root" in class $=L (users to deliver 768438032Speter locally, even if a hub or relay exists) by default. 768538032Speter This is because of the known bug where definition of 768638032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 768738032Speter both and deliver into the local mailbox. 768838032Speter CONFIG: Move up bitdomain and uudomain handling so that they 768938032Speter are done before .UUCP class matching; uudomain was 769038032Speter reported as ineffective before. This also frees up 769138032Speter diversion 8 for future use. Problem reported by Kimmo 769238032Speter Suominen. 769338032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 769438032Speter into host names. As pointed out by Jonathan Kamens, 769538032Speter these are often used because either the forward or reverse 769638032Speter mapping is broken; this translation makes it broken again. 769738032Speter DOC: Clarify $@ and $: in the Install & Op Guide.

From 772438032Speter Bob Campbell at U.C. Berkeley. 772538032Speter Security fix: group ids were not completely set when programs 772638032Speter were invoked. This caused programs to have group 772738032Speter permissions they should not have had (usually group 772838032Speter daemon instead of their own group). In particular, 772938032Speter Perl scripts would refuse to run. 773038032Speter Security: check to make sure files that are written are not 773138032Speter symbolic links (at least under some circumstances). 773238032Speter Although this does not respond to a specific known 773338032Speter attack, it's just a good idea. Suggested by 773438032Speter Christian Wettergren. 773538032Speter Security fix: if a user had an NFS mounted home directory on 773638032Speter a system with a restricted shell listed in their 773738032Speter /etc/passwd entry, they could still execute any 773838032Speter program by putting that in their .forward file. 773938032Speter This fix prevents that by insisting that their shell 774038032Speter appear in /etc/shells before allowing a .forward to 774138032Speter execute a program or write a file. You can disable 774238032Speter this by putting "*" in /etc/shells. It also won't 774338032Speter permit world-writable :include: files to reference 774438032Speter programs or files (there's no way to disable this). 774543730Speter These behaviors are only one level deep -- for 774638032Speter example, it is legal for a world-writable :include: 774738032Speter file to reference an alias that writes a file, on 774838032Speter the assumption that the alias file is well controlled. 774938032Speter Security fix: root was not treated suspiciously enough when 775038032Speter looking into subdirectories. This would potentially 775138032Speter allow a cracker to examine files that were publicly 775238032Speter readable but in a non-publicly searchable directory. 775338032Speter Fix a problem that causes an error on QUIT on a cached 775438032Speter connection to create problems on the current job. 775538032Speter These are typically unrelated, so errors occur in 775638032Speter the wrong place. 775738032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 775838032Speter runs more responsive to load average, and fixes a 775938032Speter problem that ignored the load average in locally 776038032Speter generated mail. From Eric Wassenaar. 776138032Speter Fix possible core dump on aliases with null LHS. From 776238032Speter John Orthoefer of BB&N. 776338032Speter Revert to using flock() whenever possible -- there are just 776438032Speter too many bugs in fcntl() locking, particularly over 776538032Speter NFS, that cause sendmail to fail in perverse ways. 776638032Speter Fix a bug that causes the connection cache to get confused 776738032Speter when sending error messages. This resulted in 776838032Speter "unexpected close" messages. It should fix itself 776938032Speter on the following queue run. Problem noted by 777038032Speter Liudvikas Bukys of the University of Rochester. 777138032Speter Include $k in $=k as documented in the Install & Op Guide. 777238032Speter This seems odd, but it was documented.... From 777338032Speter Michael Corrigan of UCSD. 777438032Speter Fix problem that caused :include:s from alias files to be 777538032Speter forced to be owned by root instead of daemon 777638032Speter (actually DefUid). From Tim Irvin. 777738032Speter Diagnose unrecognized I option values -- from Mortin Forssen 777838032Speter of the Chalmers University of Technology. 777938032Speter Make "error" mailer work consistently when there is no error 778038032Speter code associated with it -- previously it returned OK 778138032Speter even though there was a real problem. Now it assumes 778238032Speter EX_UNAVAILABLE. 778338032Speter Fix bug that caused the last header line of messages that had 778438032Speter no body and which were terminated with EOF instead of 778538032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 778638032Speter Fix core dump on SMTP mail to programs that failed -- it tried 778738032Speter to go to a "next MX host" when none existed, causing 778838032Speter a core dump. From der Mouse at McGill University. 778938032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 779038032Speter this makes it easier to turn it off (using 779138032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 779238032Speter Fix YP_MASTER_NAME store to use the unupdated result of 779338032Speter gethostname() (instead of myhostname(), which tries 779438032Speter to fully qualify the name) to be consistent with 779538032Speter SunOS. If your hostname is unqualified, this fixes 779638032Speter transfers to slave servers. Bug noted by Keith 779738032Speter McMillan of Ameritech Services, Inc. 779838032Speter Fix Ultrix problem: gethostbyname() can return a very large 779938032Speter (> 500) h_length field, which causes the sockaddr 780038032Speter to be trashed. Use the size of the sockaddr instead. 780138032Speter Fix from Bob Manson of Ohio State. 780238032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 780338032Speter defined -- this confuses gethostbyname on hosts 780438032Speter file lookups, which doesn't understand the trailing 780538032Speter dot convention. 780638032Speter Log SMTP server subprocesses that die with a signal instead 780738032Speter of from a clean exit. 780838032Speter If you don't have option "I" set, don't assume that a DNS 780938032Speter "host unknown" message is authoritative -- it 781038032Speter might still be found in /etc/hosts. 781138032Speter Fix a problem that would cause Deferred: messages to be sent 781238032Speter as the subject of an error message, even though the 781338032Speter actual cause of a message was more severe than that. 781438032Speter Problem noted by Chris Seabrook of OSSI. 781538032Speter Fix race condition in DBM alias file locking. From Kyle 781638032Speter Jones of UUNET. 781738032Speter Limit delivery syslog line length to avoid bugs in some 781838032Speter versions of syslog(3). This adds a new compile time 781938032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 782038032Speter University, which is in turn derived from IDA. 782138032Speter Fix quotes inside of comments in addresses -- previously 782238032Speter it insisted that they be balanced, but the 822 spec 782338032Speter says that they should be ignored. 782438032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 782538032Speter debugging). This also evaluates ruleset 89, if set 782638032Speter (with the null input), and logs the result. This 782738032Speter should be used sparingly, since the rewrite process 782838032Speter is not reentrant. 782938032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 783038032Speter documented in the Bat Book. 783138032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 783238032Speter return an error message and did not requeue the message. 783338032Speter Fix based on code from Roland Dirlewanger of 783438032Speter Reseau Regional Aquarel, Bordeaux, France. 783538032Speter Fix a problem that caused a seg fault if you got a 421 error 783638032Speter code during some parts of connection initialization. 783738032Speter I've only seen this when talking to buggy mailers on 783838032Speter the other end, but it shouldn't give a seg fault in 783938032Speter any case. From Amir Plivatsky. 784038032Speter Fix core dump caused by a ruleset call that returns null. 784138032Speter Fix from Bryan Costales of ICSI. 784238032Speter Full-Name: field was being ignored.

From Vince 787638032Speter DeMarco. 787738032Speter Fix a glitch that sometimes caused :include:s that pointed to 787838032Speter NFS filesystems that were down to give an "aliasing/ 787938032Speter forwarding loop broken" message instead of queueing 788038032Speter the message for retry. Noted by William C Fenner of 788138032Speter the NRL Connection Machine Facility. 788238032Speter Fix a problem that could cause a core dump if the input sequence 788338032Speter had (or somehow acquired) a \231 character. 788438032Speter Make sure that route-addrs always have <angle brackets> around 788538032Speter them in non-SMTP envelopes (SMTP envelopes already do 788638032Speter this properly). 788738032Speter Avoid weird headers on unbalanced punctuation of the form: 788838032Speter ``Joe User <user)'' -- this caused reference to the 788938032Speter null macro. Fix from Rick McCarty of IO.COM. 789038032Speter Fix a problem that caused an alias "user: user@local.host" to 789138032Speter not have the QNOTREMOTE bit set; this caused configs 789238032Speter to act as if FEATURE(notsticky) was defined even when 789338032Speter it was not. The effect of the problem was to make it 789438032Speter very hard to to set up satellite sites that had a few 789538032Speter local accounts, with everything else forwarded to a 789638032Speter corporate hub. Reported by Detlef Drewanz of the 789738032Speter University of Rostock and Mark Frost of NCD. 789838032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 789938032Speter addresses. This is more efficient (fewer name server 790038032Speter calls) and fixes certain unusual configurations, such 790138032Speter as those that have ruleset 4 do something that is 790238032Speter non-idempotent unless a mailer-specific ruleset did 790338032Speter something else.

Briefly, if you are sending to host 797238032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 797338032Speter "foo!baz" remains "foo!baz", and anything else has 797438032Speter the local name prepended. 797538032Speter CONFIG: portability fixes for HP-UX. 797638032Speter DOC: several minor problems fixed in the Install & Op Guide. 797738032Speter MAKEMAP: fix core dump problem on lines that are too long or 797838032Speter which lack newline. From Mark Delany. 797938032Speter MAILSTATS: print sums of columns (total messages & kbytes 798038032Speter in and out of the system). From Tom Ferrin of UC 798138032Speter San Francisco Computer Graphics Lab. 798238032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 798338032Speter On HP-UX, /etc/sendmail.cf has been moved to 798438032Speter /usr/lib/sendmail.cf to match HP sendmail. 798538032Speter Permissions have been tightened up on world-writable 798638032Speter :include: files and accounts that have shells 798738032Speter that are not listed in /etc/shells. This may 798838032Speter cause some .forward files that have worked 798938032Speter before to start failing. 799038032Speter SIGUSR1 dumps some state to the log. 799138032Speter NEW FILES: 799238032Speter src/Makefile.DGUX 799338032Speter src/Makefile.Dynix 799438032Speter src/Makefile.FreeBSD 799538032Speter src/Makefile.Mach386 799638032Speter src/Makefile.NetBSD 799738032Speter src/Makefile.RISCos 799838032Speter src/Makefile.SCO 799938032Speter src/Makefile.SVR4 800038032Speter src/Makefile.Titan 800138032Speter cf/mailer/pop.m4 800238032Speter cf/ostype/bsdi1.0.m4 800338032Speter cf/ostype/dgux.m4 800438032Speter cf/ostype/dynix3.2.m4 800538032Speter cf/ostype/sco3.2.m4 800638032Speter makemap/Makefile.dist 800738032Speter praliases/Makefile.dist 800838032Speter 800964562Sgshapiro8.6.4/8.6.4 1993/10/31 801038032Speter Repair core-dump problem (write to read-only memory segment) 801138032Speter if you fall back to the return-to-Postmaster case in 801238032Speter savemail. Problem reported by Richard Liu. 801338032Speter Immediately diagnose bogus sender addresses in SMTP. This 801438032Speter makes quite certain that crackers can't use this 801538032Speter class of attack. 801638032Speter Reliability Fix: check return value from fclose() and fsync() 801738032Speter in a few critical places. 801838032Speter Minor problem in initsys() that reversed a condition for 801938032Speter redirecting the output channel on queue runs. It's 802038032Speter not clear this code even does anything. From Eric 802138032Speter Wassenaar of the Dutch National Institute for Nuclear 802238032Speter and High-Energy Physics. 802338032Speter Fix some problems that caused queue runs to do "too much work", 802438032Speter such as double-reading the Errors-To: header. From 802538032Speter Eric Wassenaar. 802638032Speter Error messages on writing the temporary file (including the 802738032Speter data file) were getting suppressed in SMTP -- this 802838032Speter fix causes them to be properly reported. From Eric 802938032Speter Wassenaar. 803038032Speter Some changes to support AF_UNIX sockets -- this will only 803138032Speter really become relevant in the next release, but some 803238032Speter people need it for local patches. From Michael 803338032Speter Corrigan of UC San Diego. 803438032Speter Use dynamically allocated memory (instead of static buffers) 803538032Speter for macros defined in initsys() and settime(); since 803638032Speter these can have different values depending on which 803738032Speter envelope they are in. From Eric Wassenaar. 803838032Speter Improve logging to show ctladdr on to= logging; this tells you 803938032Speter what uid/gid processes ran as. 804038032Speter Fix a problem that caused error messages to be discarded if 804138032Speter the sender address was unparseable for some reason; 804238032Speter this was supposed to fall back to the "return to 804338032Speter postmaster" case. 804438032Speter Improve aliaswait backoff algorithm. 804538032Speter Portability patches for Linux (8.6.3 required another header 804638032Speter file) (from Karl London) and SCO UNIX. 804738032Speter CONFIG: patch prog mailer to not strip host name off of envelope 804838032Speter addresses (so that it matches local again). From 804938032Speter Christopher Davis. 805038032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 805138032Speter this prevents uux from seeing lines with null names like 805238032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 805338032Speter Nakamura of Kyoto University. 805438032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 805538032Speter it shouldn't fail miserably. From Motonori Nakamura. 805638032Speter 805764562Sgshapiro8.6.2/8.6.2 1993/10/15 805838032Speter Put a "successful delivery" message in the transcript for 805938032Speter addresses that get return-receipts. 806038032Speter Put a prominent "this is only a warning" message in warning 806138032Speter messages -- some people don't read carefully enough 806238032Speter and end up sending the message several times. 806338032Speter Include reason for temporary failure in the "warning" return 806438032Speter message. Currently, it just says "cannot send for 806538032Speter four hours". 806638032Speter Fix the "Original message received" time generated for 806738032Speter returntosender messages. It was previously listed as 806838032Speter the current time. Bug reported by Eric Hagberg of 806938032Speter Cornell University Medical College. 807038032Speter If there is an error when writing the body of a message, 807138032Speter don't send the trailing dot and wait for a response 807238032Speter in sender SMTP, as this could cause the connection to 807338032Speter hang up under some bizarre circumstances. From Eric 807438032Speter Wassenaar. 807538032Speter Fix some server SMTP synchronization problems caused when 807638032Speter connections fail during message collection. From 807738032Speter Eric Wassenaar. 807838032Speter Fix a problem that can cause srvrsmtp to reject mail if the 807938032Speter name server is down -- it accepts the RCPT but rejects 808038032Speter the DATA command. Problem reported by Jim Murray of 808138032Speter Stratus. 808238032Speter Fix a problem that can cause core dumps if the config file 808338032Speter incorrectly resolves to a null hostname. Reported by 808438032Speter Allan Johannesen of WPI. 808538032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 808638032Speter by non-root users were not put into 808738032Speter X-Authentication-Warning:s as intended because the 808843730Speter config file hadn't set the PrivacyOptions yet. Fix 808938032Speter from Sven-Ove Westberg of the University of Lulea. 809038032Speter Under very odd circumstances, the alias file rebuild code 809138032Speter could get confused as to whether a database was 809238032Speter open or not. 809338032Speter Check "vendor code" on the end of V lines -- this is 809438032Speter intended to provide a hook for vendor-specific 809538032Speter configuration syntax. (This is a "new feature", 809638032Speter but I've made an exception to my rule in a belief 809738032Speter that this is a highly exceptional case.) 809838032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 809938032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 810038032Speter (from Jon Forrest of UC Berkeley) 810138032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 810238032Speter 810364562Sgshapiro8.6.1/8.6 1993/10/08 810438032Speter Portability fixes for A/UX and Encore UMAX V. 810538032Speter Fix error message handling -- if you had a name server down 810638032Speter causing an error during parsing, that message was never 810738032Speter propagated to the queue file. 810838032Speter 810964562Sgshapiro8.6/8.6 1993/10/05 811038032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 811138032Speter conf.h (other systems have the same bug). 811238032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 811338032Speter getdtablesize() instead of sysconf(); a disturbingly 811438032Speter large number of systems defined _SC_OPEN_MAX in the 811538032Speter header files but don't have the syscall. 811638032Speter Another patch to really truly ignore MX records in getcanonname 811738032Speter if trymx == FALSE. 811838032Speter Fix problem that caused the "250 IAA25499 Message accepted for 811938032Speter delivery" message to be omitted if there was an error 812038032Speter in the header of the message (e.g., a bad Errors-To: 812138032Speter line). Pointed out by Michael Corrigan of UCSD. 812238032Speter Announce name of host we are chatting when we get errors; this 812338032Speter is an IDA-ism suggested by Christophe Wolfhugel. 812438032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 812538032Speter Australian Artificial Intelligence Institute), SCO Unix 812638032Speter (from Murray Kucherawy of Hookup Communication Corp.), 812738032Speter NeXT (from Vince DeMarco and myself), Linux (from 812838032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 812938032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 813038032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 813138032Speter Some changes to get around gcc optimizer bugs. From Takahiro 813238032Speter Kanbe. 813338032Speter Fix error recovery in queueup if another tf file of the same 813438032Speter name already exists. Problem stumbled over by Bill 813538032Speter Wisner of The Well. 813638032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 813738032Speter Problem noted by Keith McMillan of Ameritech Services. 813838032Speter Deal with group permissions properly when opening .forward and 813938032Speter :include: files. This relaxes the 8.1C restrictions 814038032Speter slightly more. This includes proper setting of groups 814138032Speter when reading :include: files, allowing you to read some 814238032Speter files that you should be able to read but have previously 814338032Speter been denied unless you owned them or they had "other" 814438032Speter read permission. 814538032Speter Make certain that $j is in $=w (after the .cf is read) so that 814638032Speter if the user is forced to override some silly system, 814738032Speter MX suppression will still work. 814838032Speter Fix a couple of efficiency problems where newstr was double- 814938032Speter calling expensive routines. In at least one case, it 815038032Speter wasn't guaranteed that they would always return the 815138032Speter same result. Problem noted by Christophe Wolfhugel. 815238032Speter Fix null pointer dereference in putoutmsg -- only on an error 815338032Speter condition from a non-SMTP mailer. From Motonori 815438032Speter Nakamura. 815538032Speter Macro expand "C" line class definitions before scanning so that 815638032Speter "CX $Z" works. 815738032Speter Fix problem that caused error message to be sent while still 815838032Speter trying to send the original message if the connection 815938032Speter is closed during a DATA command after getting an error 816038032Speter on an RCPT command (pretty obscure). Problem reported 816138032Speter by John Myers of CMU. 816238032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 816338032Speter term bug. 816438032Speter Fix a nasty bug causing core dumps when returning the "warning: 816538032Speter cannot deliver for N hours -- will keep trying" message; 816643730Speter it only occurred if you had PostmasterCopy set and 816738032Speter only on some architectures. Although sendmail would 816838032Speter keep trying, it would send error messages on each 816938032Speter queue interval. This is an important fix. 817038032Speter Allow u and g options to take user and group names respectively. 817138032Speter Don't do a chdir into the queue directory in -bt mode to make 817238032Speter ruleset testing a bit easier. 817338032Speter Don't allow users to turn off logging (using -oL) on the command 817438032Speter line -- command line can only raise, not lower, logging 817538032Speter level. 817638032Speter Set $u to the original recipient on the SMTP transaction or on 817738032Speter the command line. This is only done if there is exactly 817838032Speter one recipient. Technically, this does not meet the 817938032Speter specs, because it does not guarantee a domain on the 818038032Speter address. 818138032Speter Fix a problem that dumped error messages on bad addresses if 818238032Speter you used the -t flag. Problem noted by Josh Smith of 818338032Speter Harvey Mudd College. 818438032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 818538032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 818638032Speter avoid the problem of people who use angle brackets in 818738032Speter their full name information. 818838032Speter Fix a null pointer dereference if you set option "l", have 818938032Speter an Errors-To: header in the message, and have Errors-To: 819038032Speter defined in the config file H lines. From J.R. Oldroyd. 819138032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 819238032Speter wrong when compiling. Suggested by Rick McCarty of TI. 819338032Speter Fix a problem that could pass negative SIZE parameter if the 819438032Speter df file got lost; this would cause servers to always 819538032Speter give a temporary failure, making the problem even worse. 819638032Speter Problem noted by Allan Johannesen of WPI. 819738032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 819838032Speter protocol timeouts (30s default). Requested by Murray 819938032Speter Kucherawy of HookUp Communication Corp. to handle bogus 820038032Speter PC TCP/IP implementations. 820138032Speter Change $w default definition to be just the first component of 820238032Speter the domain name on config level 5. The $j macro defaults 820338032Speter to the FQDN; $m remains as before. This lets well-behaved 820438032Speter config files use any of the short, long, or subdomain 820538032Speter names. 820638032Speter Add makesendmail script in src to try to automate multi-architecture 820738032Speter builds. I know, this is sub-optimal, but it is still 820838032Speter helpful. 820938032Speter Fix very obscure race condition that can cause a queue run to 821038032Speter get a queue file for an already completed job. This 821138032Speter problem has existed for years. Problem noted by the 821238032Speter long suffering Allan Johannesen of WPI. 821338032Speter Fix a problem that caused the raw sender name to be passed to 821438032Speter udbsender instead of the canonified name -- this caused 821538032Speter it to sometimes miss records that it should have found. 821638032Speter Relax check of name on HELO packet so that a program using -bs 821738032Speter that claims to be itself works properly. 821838032Speter Restore rewriting of $: part of address through 2, R, 4 in 821938032Speter buildaddr -- this requires passing a lot of flags to get 822038032Speter it right. Unlike old versions, this ONLY rewrites 822138032Speter recipient addresses, not sender addresses. 822238032Speter Fix a bug that caused core dumps in config files that cannot 822338032Speter resolve /file/name style addresses. Fix from Jonathan 822438032Speter Kamens of OpenVision Technologies. 822538032Speter Fix problem with fcntl locking that can cause error returns to 822638032Speter be lost if the lock is lost; this required fully 822738032Speter queueing everything, dropping the envelope (so errors 822838032Speter would get returned), and then re-reading the queue from 822938032Speter scratch. 823038032Speter Fix a problem that caused aliases that redefine an otherwise 823138032Speter true address to still send to the original address 823238032Speter if and only if the alias failed in certain bizarre 823338032Speter ways (e.g, if they pointed at a list:; syntax address). 823438032Speter Problem pointed out by Jonathan Kamens. 823538032Speter Remove support for frozen configuration files. They caused 823638032Speter more trouble than it was worth. 823738032Speter Fix problem that can cause error messages to get ignored when 823838032Speter using both -odb and -t flags. Problem noted by Rob 823938032Speter McNicholas at U.C. Berkeley. 824038032Speter Include all "normal" variations on hostname in $=w. For example, 824138032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 824238032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 824338032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 824438032Speter the queue. 824538032Speter Reset SmtpPhase global on initial connection creation so that 824638032Speter messages don't come out with stale information. 824738032Speter Pass an "ext" argument to lockfile so that error/log messages 824838032Speter will properly reflect the true filename being locked. 824938032Speter Put all [...] address forms into $=w -- this eliminates the need 825038032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 825138032Speter Myers of CMU. 825238032Speter Fix a bug that can cause qf files to be left around even after 825338032Speter an SMTP RSET command. Problem and fix from Michael 825438032Speter Corrigan. 825543730Speter Don't send a PostmasterCopy to errors when the Precedence: is 825638032Speter negative. Error reports still go to the envelope 825738032Speter sender address. 825838032Speter Add LA_SHORT for load averages. 825938032Speter Lock sendmail.st file when posting statistics. 826038032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 826138032Speter set the size of the TCP send and receive buffers; if you 826238032Speter run over a slow slip line you may need to set these down 826338032Speter (although it would be better to fix the SLIP implementation 826438032Speter so that it's not necessary to recompile every program 826538032Speter that does bulk data transfer). 826638032Speter Allow null defaults on $( ... $) lookups. Problem reported by 826738032Speter Amir Plivatsky. 826838032Speter Diagnose crufty S and V config lines. This resulted from an 826938032Speter observation that some people were using the SITE macro 827038032Speter without the SITECONFIG macro first, which was causing 827138032Speter bogus config files that were not caught. 827238032Speter Fix makemap -f flag to turn off case folding (it was turning it 827338032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 827438032Speter Fix a problem that caused multiple error messages to be sent if 827538032Speter you used "sendmail -t -oem -odb", your system uses fcntl 827638032Speter locking, and one of the recipient addresses is unknown. 827738032Speter Reset uid earlier in include() so that recursive .forwards or 827838032Speter :include:s don't use the wrong uid. 827938032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 828038032Speter called, the code to recover the descriptor was broken. 828138032Speter This sometimes (only sometimes) caused problems with the 828238032Speter alias file. Fix from Motonori Nakamura. 828338032Speter Fix a problem that caused aliaswait to go into infinite recursion 828438032Speter if the @:@ metasymbol wasn't found in the alias file. 828538032Speter Improve error message on newaliases if database files cannot be 828638032Speter opened or if running with no database format defined. 828738032Speter Do a better estimation of the size of error messages when NoReturn 828838032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 828938032Speter Fix a problem causing the "c" option (don't connect to expensive 829038032Speter mailers) to be ignored in SMTP. Problem noted and the 829138032Speter solution suggested by Robert Elz of The University of 829238032Speter Melbourne. 829338032Speter Improve connection caching algorithm by passing "[host]" to 829438032Speter hostsignature, which strips the square brackets and 829538032Speter returns the real name. This allows mailertable entries 829638032Speter to match regular entries. 829738032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 829838032Speter feature, even if it doesn't work right. 829938032Speter Catch and log attempts to try the "wiz" command in server SMTP. 830038032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 830138032Speter Be more generous at assigning $z to the home directory -- do this 830238032Speter for programs that are specified through a .forward file. 830338032Speter Fix from Andrew Chang of Sun Microsystems. 830438032Speter Always save a fatal error message in preference to a non-fatal 830538032Speter error message so that the "subject" line of return 830638032Speter messages is the best possible. 830738032Speter CONFIG: reduce the number of quotes needed to quote configuration 830838032Speter parameters with commas: two quotes should work now, e.g., 830938032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 831038032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 831138032Speter connections (domain-ized UUCP). 831238032Speter CONFIG: fix bug in default maps (-o must be before database file 831364562Sgshapiro name). Pointed out by Christophe Wolfhugel. 831438032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 831538032Speter DNS. This would presumably be used in UUCP islands. 831638032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 831738032Speter CONFIG: log $u in Received: line. This is in technical violation 831838032Speter of the standards, since it doesn't guarantee a domain 831938032Speter on the address. 832038032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 832138032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 832238032Speter the "m" flag should you want it. Apparently some Solaris 2.2 832338032Speter installations can't handle multiple local recipients. 832438032Speter Problem noted by Josh Smith. 832538032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 832638032Speter CONFIG: change default version level from 4 to 5. 832738032Speter CONFIG: add FEATURE(nullclient) to create a config file that 832838032Speter forwards all mail to a hub without ever looking at the 832938032Speter addresses in any detail. 833038032Speter CONFIG: properly strip mailer: information off of relays when 833138032Speter used to change .BITNET form into %-hack form. 833238032Speter CONFIG: fix a problem that caused infinite loops if presented 833338032Speter with an address such as "!foo". 833438032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 833538032Speter the reverse "PTR" mapping is broken. There's a better 833638032Speter way to do this, but the change is fairly major and I 833738032Speter want to hold it for another release. Problem noted by 833838032Speter Bret Marquis. 833938032Speter 834064562Sgshapiro8.5/8.5 1993/07/23 834138032Speter Serious bug: if you used a command line recipient that was unknown 834238032Speter sendmail would not send a return message (it was treating 834338032Speter everything as though it had an SMTP-style client that 834438032Speter would do the return itself). Problem noted by Josh Smith. 834538032Speter Change "trymx" option in getcanonname() to ignore all MX data, 834638032Speter even during a T_ANY query. This actually didn't break 834738032Speter anything, because the only time you called getcanonname 834838032Speter with !trymx was if you already knew there were no MX 834938032Speter records, but it is somewhat cleaner. From Motonori 835038032Speter Nakamura. 835138032Speter Don't call getcanonname from getmxrr if you already know there 835238032Speter are no DNS records matching the name. 835338032Speter Fix a problem causing error messages to always include "The 835438032Speter original message was received ... from localhost". 835538032Speter The correct original host information is now included. 835638032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 835738032Speter version of "test" doesn't have the -x flag). Change it 835838032Speter to use -f instead. From John Myers. 835938032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 836038032Speter esmtp -- it should be smtp. 836138032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 836238032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 836338032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 836438032Speter this cleans up the configs somewhat. This fixes a serious 836538032Speter problem that caused route-addrs to get mistaken as relays, 836638032Speter pointed out by John Myers. WARNING: this also causes 836738032Speter the default on SMART_HOST to change from "suucp" to 836838032Speter "relay" if you have MAILER(smtp) specified. 836938032Speter 837064562Sgshapiro8.4/8.4 1993/07/22 837138032Speter Add option `w'. If you receive a message that comes to you because 837238032Speter you are the best (lowest preference) target of an MX, and 837338032Speter you haven't explicitly recognized the source MX host in 837438032Speter your .cf file, this option will cause you to try the target 837538032Speter host directly (as if there were no MX for it at all). If 837638032Speter `w' is not set, this case is a configuration error. 837738032Speter Beware: if `w' is set, senders may get bogus errors like 837838032Speter "message timed out" or "host unknown" for problems that 837938032Speter are really configuration errors. This option is 838038032Speter disrecommended, provided only for compatibility with 838138032Speter UIUC sendmail. 838238032Speter Fix a problem that caused the incoming socket to be left open 838338032Speter when sendmail forks after the DATA command. This caused 838438032Speter calling systems to wait in FIN_WAIT_2 state until the 838538032Speter entire list was processed and the child closed -- a 838638032Speter potentially prodigious amount of time. Problem noted 838738032Speter by Neil Rickert. 838838032Speter Fix problem (created in 6.64) that caused mail sent to multiple 838938032Speter addresses, one of which was a bad address, to completely 839038032Speter suppress the sending of the message. This changes 839138032Speter handling of EF_FATALERRS somewhat, and adds an 839238032Speter EF_GLOBALERRS flag. This also fixes a potential problem 839338032Speter with duplicate error messages if there is a syntax error 839438032Speter in the header of a message that isn't noticed until late 839538032Speter in processing. Original problem pointed out by Josh Smith 839638032Speter of Harvey Mudd College. This release includes quite a bit 839738032Speter of dickering with error handling (see below). 839838032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 839938032Speter will only hurt already-broken software and should help 840038032Speter humans. 840138032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 840238032Speter compiled in. It would never read the alias file. 840338032Speter Repair unbalanced `)' and `>' (the "open" versions are already 840438032Speter repaired). 840538032Speter Logging of "done" in dropenvelope() was incorrect: it would 840638032Speter log this even when the queue file still existed. Change 840738032Speter this to only log "done" (at log level 11) when the 840838032Speter queue file is actually removed. From John Myers. 840938032Speter Log "lost connection" in server SMTP at log level 20 if there 841038032Speter is no pending transaction. Some senders just close the 841138032Speter connection rather than sending QUIT. 841238032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 841338032Speter domains that do not have MX records -- this would cause 841438032Speter the subsequent host name lookup to fail. The problem 841538032Speter only occurred if you had FEATURE(nocanonify) set. 841638032Speter Problem noted by Rick McCarty of Texas Instruments. 841738032Speter Fix invocation of setvbuf when passed a -X flag -- I had 841838032Speter unwittingly used an ANSI C extension, and this caused 841938032Speter core dumps on some machines. 842038032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 842138032Speter Previously it just gave an empty send queue, which 842238032Speter then gave either "Need RCPT (recipient)" at the DATA 842338032Speter (confusing, since you had given an RCPT command which 842438032Speter returned 250) or just dropped the email, depending on 842538032Speter whether you were running VERBose mode. Now it usually 842638032Speter diagnoses this case as "aliasing/forwarding loop broken". 842738032Speter Unfortunately, it still doesn't adequately diagnose 842838032Speter some true error conditions. 842938032Speter Add internal concept of "warning messages" using 6xx codes. 843038032Speter These are not reported only to Postmaster. Unbalanced 843138032Speter parens, brackets, and quotes are printed as 653 codes. 843238032Speter They are always mapped to 5xx codes before use in SMTP. 843338032Speter Clean up error messages to tell both the actual address that 843438032Speter failed and the alias they arose from. This makes it 843538032Speter somewhat easier to diagnose problems. Difficulty noted 843638032Speter by Motonori Nakamura. 843738032Speter Fix a problem that inappropriately added a ctladdr to addresses 843838032Speter that shouldn't have had one during a queue run. This 843938032Speter caused error messages to be handled differently during 844038032Speter a queue run than a direct run. 844138032Speter Don't print the qf name and line number if you get errors during 844238032Speter the direct run of the queue from srvrsmtp -- this was 844338032Speter just extra stuff for users to crawl through. 844438032Speter Put command line flags on second line of pid file so you can 844538032Speter auto-restart the daemon with all appropriate arguments. 844638032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 844738032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 844838032Speter restart it. 844938032Speter Remove the ``setuid(getuid())'' in main -- this caused the 845038032Speter IDENT daemon to screw up. This required that I change 845138032Speter HASSETEUID to HASSETREUID and complicate the mode 845238032Speter changing somewhat because both Ultrix and SunOS seem 845338032Speter to have a bug causing seteuid() to set the saved uid 845438032Speter as well as the effective. The program test/t_setreuid.c 845538032Speter will test to see if your implementation of setreuid(2) 845638032Speter is appropriately functional. 845738032Speter The FallBackMX (option V) handling failed to properly identify 845838032Speter fallback to yourself -- most of the code was there, 845938032Speter but it wasn't being enabled. Problem noted by Murray 846038032Speter Kucherawy of the University of Waterloo. 846138032Speter Change :include: open timeout from ETIMEDOUT to an internal 846238032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 846338032Speter with CurHostName" in error messages, which can be 846438032Speter confusing. Reported by Jonathan Kamens of OpenVision 846538032Speter Technologies. 846638032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 846738032Speter process group id. The original fix was to get around 846838032Speter some problems with recalcitrant MUAs, but it breaks 846938032Speter any call from a shell that creates a process group id 847038032Speter different from the process id. I could try to fix 847138032Speter this by diddling the tty owner (using tcsetpgrp or 847238032Speter equivalent) but this is too likely to break other 847338032Speter things. 847438032Speter Portability changes: 847538032Speter Support -M as equivalent to -oM on Ultrix -- apparently 847638032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 847738032Speter instead of using standard flags. Oh joy. This 847843730Speter behavior reported by Jon Giltner of University 847938032Speter of Colorado. 848038032Speter SGI IRIX -- this includes several changes that should 848138032Speter help other strict ANSI compilers. 848238032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 848338032Speter Corporation. 848438032Speter Solaris running the Sun C compiler (which despite the 848538032Speter documentation apparently doesn't define 848638032Speter __STDC__ by default). 848738032Speter ConvexOS from Eric Schnoebelen of Convex. 848838032Speter Sony NEWS workstations and Omron LUNA workstations from 848938032Speter Motonori Nakamura. 849038032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 849138032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 849238032Speter several people have made a good argument that this 849338032Speter creates more problems than it solves (although this 849438032Speter may prove painful in the short run). 849538032Speter CONFIG: generalize all the relays to accept a "mailer:host" 849638032Speter format. 849738032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 849838032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 849938032Speter addresses are also passed through this ruleset. 850038032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 850138032Speter internet-style addresses would "fall off the end" of 850238032Speter ruleset zero and be interpreted as local -- however, 850338032Speter the angle brackets confused the recursive call. 850438032Speter These are now diagnosed as "Unrecognized host name". 850538032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 850638032Speter ifdef(`_MAILER_USENET_') instead of 850738032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 850838032Speter of SINTEF RUNIT, Oslo. 850938032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 851038032Speter early in ruleset 0; this allows .mc authors to bypass 851138032Speter things like the "short circuit" code for local addresses. 851238032Speter Prompted by a comment by Bill Wisner of The Well. 851338032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 851438032Speter esmtp) to send SMTP mail. This allows you to default 851538032Speter to esmtp but use a mailertable or other override to 851638032Speter deal with broken servers. This logic was pointed out 851738032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 851838032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 851938032Speter environments. Ugly as sin. 852038032Speter 852164562Sgshapiro8.3/8.3 1993/07/13 852238032Speter Fix setuid problems introduced in 8.2 that caused messages 852338032Speter like "Cannot create qfXXXXXX: Invalid argument" 852438032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 852538032Speter involved a new compile flag "HASSETEUID" that takes 852638032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 852738032Speter that the POSIX interface is broken enough to break 852838032Speter some systems badly. This includes some fixes for 852938032Speter HP-UX. Also fixes problems where the real uid is 853038032Speter not reset properly on startup (from Neil Rickert). 853138032Speter Fix a problem that caused timed out messages to not report the 853238032Speter addresses that timed out. Error messages are also more 853338032Speter "user friendly". 853438032Speter Drop required bandwidth on connections from 64 bytes/sec to 853538032Speter 16 bytes/sec. 853638032Speter Further Solaris portability changes -- doesn't require the BSD 853738032Speter compatibility library. This also adds a new 853838032Speter "HASGETDTABLESIZE" compile flag which can be used if 853938032Speter you want to use getdtablesize(2) instead of sysconf(2). 854038032Speter These are loosely based on changes from David Meyer at 854138032Speter University of Oregon. This now seems to work, at least 854238032Speter for quick test cases. 854338032Speter Fix a problem that can cause duplicate error messages to be 854438032Speter sent if you are in SMTP, you send to multiple addresses, 854538032Speter and at least one of those addresses is good and points 854638032Speter to an account that has a .forward file (whew!). 854738032Speter Fix a problem causing messages to be discarded if checkcompat() 854838032Speter returned EX_TEMPFAIL (because it didn't properly mark 854938032Speter the "to" address). Problem noted by John Myers. 855038032Speter Fix dfopen to return NULL if the open failed; I was depending 855138032Speter on fdopen(-1) returning NULL, which isn't the case. This 855238032Speter isn't serious, but does result in weird error diagnoses. 855338032Speter From Michael Corrigan. 855438032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 855538032Speter messages sent through UUCP-family mailers. Suggested 855638032Speter by Bill Wisner of The Well. 855738032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 855838032Speter include a "uucp-dom" mailer that uses domain-style 855938032Speter addressing. Suggested by Bill Wisner. 856038032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 856138032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 856238032Speter Christophe Wolfhugel. 856338032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 856438032Speter 856564562Sgshapiro8.2/8.2 1993/07/11 856638032Speter Don't drop out on config file parse errors in -bt mode. 856738032Speter On older configuration files, assume option "l" (use Errors-To 856838032Speter header) for back compatibility. NOTE: this DOES NOT 856938032Speter imply an endorsement of the Errors-To: header in any way. 857038032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 857138032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 857238032Speter SMTP server to give an error on this command, and 857338032Speter logging it in the transcript can be confusing. Fix 857438032Speter from Bill Wisner. 857538032Speter IRIX compatibility changes provided by Dan Rich 857638032Speter <drich@sandman.lerc.nasa.gov>. 857738032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 857838032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 857938032Speter <juo@klinzhai.rutgers.edu> 858038032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 858138032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 858238032Speter match the other flags in that file. 858338032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 858438032Speter Save h_errno in mci struct and improve error message display. 858538032Speter Changes from Eric Wassenaar. 858638032Speter Open /dev/null for the transcript if the create of the xf file 858738032Speter failed; this avoids at least one possible null pointer 858838032Speter reference in very weird cases. From Eric Wassenaar. 858938032Speter Clean up statistics gathering; it was over-reporting because of 859038032Speter forks. From Eric Wassenaar. 859138032Speter Fix problem that causes old Return-Path: line to override new 859238032Speter Return-Path: line (conf.c needs H_FORCE to avoid 859338032Speter re-using old value). From Motonori Nakamura. 859438032Speter Fix broken -m flag in K definition -- even if -m (match only) 859538032Speter was specified, it would still replace the key with the 859638032Speter value. Noted by Rick McCarty of Texas Instruments. 859738032Speter If the name server timed out over several days, no "timed out" 859838032Speter message would ever be sent back. The timeout code 859938032Speter has been moved from markfailure() to dropenvelope() 860038032Speter so that all such failures should be diagnosed. Pointed 860138032Speter out by Christophe Wolfhugel and others. 860238032Speter Relax safefile() constraints: directories in an include or 860338032Speter forward path must be readable by self if the controlling 860438032Speter user owns the entry, readable by all otherwise (e.g., 860538032Speter when reading your .forward file, you have to own and 860638032Speter have X permission in it; everyone needs X permission in 860738032Speter the root and directories leading up to your home); 860838032Speter include files must be readable by anyone, but need not 860938032Speter be owned by you. 861038032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 861138032Speter reading a .forward file; this gets around some problems 861238032Speter on NFS mounts if root permission is not exported and 861338032Speter the user's home directory isn't x'able. 861438032Speter Additional NeXT portability enhancements from Axel Zinser. 861538032Speter Additional HP-UX portability enhancements from Brian Bullen. 861638032Speter Add a timeout around SMTP message writes; this assumes you can 861738032Speter get throughput of at least 64 bytes/second. Note that 861838032Speter this does not impact the "datafinal" default, which 861938032Speter is separate; this is just intended to work around 862038032Speter network clogs that will occur before the final dot 862138032Speter is sent. From Eric Wassenaar. 862238032Speter Change map code to set the "include null" flag adaptively -- 862338032Speter it initially tries both, but if it finds anything 862438032Speter matching without a null it never tries again with a 862538032Speter null and vice versa. If -N is specified, it never 862638032Speter tries without the null and creates new maps with a 862738032Speter null byte. If -O is specified, it never tries with 862838032Speter the null (for efficiency). If -N and -O are specified, 862938032Speter you get -NO (get it?) lookup at all, so this would 863038032Speter be a bad idea. If you don't specify either -N or -O, 863138032Speter it adapts. 863238032Speter Fix recognition of "same from address" so that MH submissions 863338032Speter will insert the appropriate full name information; 863438032Speter this used to work and got broken somewhere along the 863538032Speter way. 863638032Speter Some changes to eliminate some unnecessary SYSERRs in the 863738032Speter log. For example, if you lost a connection, don't 863838032Speter bother reporting that fact on the connection you lost. 863938032Speter Add some "extended debugging" flags to try to track down 864038032Speter why we get occasional problems with file descriptor 864138032Speter one being closed when execing a mailer; it seems to 864238032Speter only happen when there has been another error in the 864338032Speter same transaction. This requires XDEBUG, defined 864438032Speter by default in conf.h. 864538032Speter Add "-X filename" command line flag, which logs both sides of 864638032Speter all SMTP transactions. This is intended ONLY for 864738032Speter debugging bad implementations of other mailers; start 864838032Speter it up, send a message from a mailer that is failing, 864938032Speter and then kill it off and examine the indicated log. 865038032Speter This output is not intended to be particularly human 865138032Speter readable. This also adds the HASSETVBUF compile 865238032Speter flag, defaulted on if your compiler defines __STDC__. 865338032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 865438032Speter have a local net that should get direct connects, you 865538032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 865638032Speter See cf/README for an example. 865738032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 865838032Speter sites that don't use the -d flag. 865938032Speter CONFIG: hide recipient addresses as well as sender addresses 866038032Speter behind $M if FEATURE(allmasquerade) is specified; this 866138032Speter has been requested by several people, but can break 866238032Speter local aliases. For example, if you mail to "localalias" 866338032Speter this will be rewritten as "localalias@masqueradehost"; 866438032Speter although initial delivery will work, replies will be 866538032Speter broken. Use it sparingly. 866638032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 866738032Speter to qualified domains in headers. I believe this is 866838032Speter largely equivalent to the IDA feature of the same name. 866938032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 867038032Speter to override the "system name" as your UUCP name -- 867138032Speter in particular, to use domain-ized UUCP names. From 867238032Speter Bill Wisner of The Well. 867338032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 867438032Speter first. This is currently unused in the config files, 867538032Speter but could be used in a mailertable entry. 867638032Speter 867764562Sgshapiro8.1C/8.1B 1993/06/27 867838032Speter Serious security bug fix: it was possible to read any file on 867938032Speter the system, regardless of ownership and permissions. 868038032Speter If a subroutine returns a fully qualified address, return it 868138032Speter immediately instead of feeding it back into rewriting. 868238032Speter This fixes a problem with mailertable lookups. 868338032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 868438032Speter 868564562Sgshapiro8.1B/8.1A 1993/06/12 868638032Speter Serious bug fix: pattern matching backup algorithm stepped by 868738032Speter two tokens in classes instead of one. Found by Claus 868838032Speter Assmann at University of Kiel, Germany. 868938032Speter 869064562Sgshapiro8.1A/8.1A 1993/06/08 869138032Speter Another mailertable fix.... 869238032Speter 869364562Sgshapiro8.1/8.1 1993/06/07 869438032Speter 4.4BSD freeze.
