None of the 1398841Sgshapiro sendmail supplied configuration files use this option hence 1498841Sgshapiro they are not vulnerable. Problem noted independently by 1598841Sgshapiro Joost Pol of PINE Internet and Anton Rang of Sun Microsystems. 1698841Sgshapiro Unprintable characters in responses from DNS servers for the DNS 1798841Sgshapiro map type are changed to 'X' to avoid potential problems 1898841Sgshapiro with rogue DNS servers. 1998841Sgshapiro Require a suboption when setting the Milter option. Problem noted 2098841Sgshapiro by Bryan Costales. 2198841Sgshapiro Do not silently overwrite command line settings for 2298841Sgshapiro DirectSubmissionModifiers. Problem noted by Bryan 2398841Sgshapiro Costales. 2498841Sgshapiro Prevent a segmentation fault when clearing the event list by 2598841Sgshapiro turning off alarms before checking if event list is 2698841Sgshapiro empty. Problem noted by Allan E Johannesen of Worcester 2798841Sgshapiro Polytechnic Institute. 2898841Sgshapiro Close a potential race condition in transitioning a memory buffered 2998841Sgshapiro file onto disk. From Janani Devarajan of Sun Microsystems. 3098841Sgshapiro Portability: 3198841Sgshapiro Include paths.h on Linux systems running glibc 2.0 or later 3298841Sgshapiro to get the definition for _PATH_SENDMAIL, used by 3398841Sgshapiro rmail and vacation. Problem noted by Kevin 3498841Sgshapiro A. McGrail of Peregrine Hardware. 3598841Sgshapiro NOTE: Linux appears to have broken flock() again. Unless 3698841Sgshapiro the bug is fixed before sendmail 8.13 is shipped, 3798841Sgshapiro 8.13 will change the default locking method to 3898841Sgshapiro fcntl() for Linux kernel 2.4 and later. You may 3998841Sgshapiro want to do this in 8.12 by compiling with 4098841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 4198841Sgshapiro related programs to match locking techniques. 4298841Sgshapiro 4398121Sgshapiro8.12.4/8.12.4 2002/06/03 4498121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 4598121Sgshapiro can leave systems open to a local denial of service 4698121Sgshapiro attack. Be sure to read the "FILE AND MAP PERMISSIONS" 4798121Sgshapiro section of the top level README for more information. 4898121Sgshapiro Problem noted by lumpy. 4998121Sgshapiro Use TempFileMode (defaults to 0600) for the permissions of PidFile 5098121Sgshapiro instead of 0644. 5198121Sgshapiro Change the default file permissions for new alias database files 5298121Sgshapiro from 0644 to 0640. This can be overridden at compile time 5398121Sgshapiro by setting the DBMMODE macro. 5498121Sgshapiro Fix a potential core dump problem if the environment variable 5598121Sgshapiro NAME is set. Problem noted by Beth A. Chaney of 5698121Sgshapiro Purdue University. 5798121Sgshapiro Expand macros before passing them to libmilter. Problem noted 5898121Sgshapiro by Jose Marcio Martins da Cruz of Ecole Nationale 5998121Sgshapiro Superieure des Mines de Paris. 6098121Sgshapiro Rewind the df (message body) before truncating it when libmilter 6198121Sgshapiro replaces the body of a message. Problem noted by Gisle Aas 6298121Sgshapiro of Active State. 6398121Sgshapiro Change SMTP reply code for AUTH failure from 500 to 535 and the 6498121Sgshapiro initial zero-length response to "=" per RFC 2554. Patches 6598121Sgshapiro from Kenneth Murchison of Oceana Matrix Ltd. 6698121Sgshapiro Do not try to fix broken message/rfc822 MIME attachments by 6798121Sgshapiro inserting a MIME-Version: header when MaxMimeHeaderLength 6898121Sgshapiro is set and no 8 to 7 bit conversion is needed. Based on 6998121Sgshapiro patch from Rehor Petr of ICZ (Czech Republic). 7098121Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" if the connection 7198121Sgshapiro is rejected anyway. Noted by Chris Loelke. 7298121Sgshapiro Mention the submission mail queue in the mailq man page. Requested 7398121Sgshapiro by Bill Fenner of AT&T. 7498121Sgshapiro Set ${msg_size} macro when reading a message from the command line 7598121Sgshapiro or the queue. 7698121Sgshapiro Detach from shared memory before dropping privileges back to 7798121Sgshapiro user who started sendmail. 7898121Sgshapiro If AllowBogusHELO is set to false (default) then also complain if 7998121Sgshapiro the argument to HELO/EHLO contains white space. Suggested 8098121Sgshapiro by Seva Gluschenko of Cronyx Plus. 8198121Sgshapiro Allow symbolicly linked forward files in writable directory paths 8298121Sgshapiro if both ForwardFileInUnsafeDirPath and 8398121Sgshapiro LinkedForwardFileInWritableDir DontBlameSendmail options 8498121Sgshapiro are set. Problem noted by Werner Spirk of 8598121Sgshapiro Leibniz-Rechenzentrum Munich. 8698121Sgshapiro Portability: 8798121Sgshapiro Operating systems that lack the ftruncate() call will not 8898121Sgshapiro be able to use Milter's body replacement feature. 8998121Sgshapiro This only affects Altos, Maxion, and MPE/iX. 9098121Sgshapiro Digital UNIX 5.0 has changed flock() semantics to be 9198121Sgshapiro non-compliant. Problem noted by Martin Mokrejs of 9298121Sgshapiro Charles University in Prague. 9398121Sgshapiro The sparc64 port of FreeBSD 5.0 now supports shared 9498121Sgshapiro memory. 9598121Sgshapiro CONFIG: FEATURE(`preserve_luser_host') needs the macro map. 9698121Sgshapiro Problem noted by Andrzej Filip. 9798121Sgshapiro CONFIG: Using 'local:' as a mailertable value with 9898121Sgshapiro FEATURE(`preserve_luser_host') and LUSER_RELAY caused mail 9998121Sgshapiro to be misaddressed. Problem noted by Andrzej Filip. 10098121Sgshapiro CONFIG: Provide a workaround for DNS based rejection lists that 10198121Sgshapiro fail for AAAA queries. Problem noted by Chris Boyd. 10298121Sgshapiro CONFIG: Accept the machine's hostname as resolvable when checking 10398121Sgshapiro the sender address. This allows locally submitted mail to 10498121Sgshapiro be accepted if the machine isn't connected to a nameserver 10598121Sgshapiro and doesn't have an /etc/hosts entry for itself. Problem 10698121Sgshapiro noted by Robert Watson of the TrustedBSD Project. 10798121Sgshapiro CONFIG: Use deferred expansion for checking the ${deliveryMode} 10898121Sgshapiro macro in case the SMTP VERB command is used. Problem 10998121Sgshapiro noted by Bryan Costales. 11098121Sgshapiro CONFIG: Avoid a duplicate '@domain' virtusertable lookup if no 11198121Sgshapiro matches are found. Fix from Andrzej Filip. 11298121Sgshapiro CONFIG: Fix wording in default dnsbl rejection message. Suggested 11398121Sgshapiro by Lou Katz of Metron Computerware, Ltd. 11498121Sgshapiro CONFIG: Add mailer cyrusv2 for Cyrus V2. Contributed by 11598121Sgshapiro Kenneth Murchison of Oceana Matrix Ltd. 11698121Sgshapiro CONTRIB: Fix wording in default dnsblaccess rejection message to 11798121Sgshapiro match dnsbl change. 11898121Sgshapiro DEVTOOLS: Add new option for access mode of statistics file, 11998121Sgshapiro confSTMODE, which specifies the permissions when initially 12098121Sgshapiro installing the sendmail statistics file. 12198121Sgshapiro LIBMILTER: Mark the listening socket as close-on-exec in case 12298121Sgshapiro a user's filter starts other applications. 12398121Sgshapiro LIBSM: Allow the MBDB initialize, lookup, and/or terminate 12498121Sgshapiro functions in SmMbdbTypes to be set to NULL. 12598121Sgshapiro MAKEMAP: Change the default file permissions for new databases from 12698121Sgshapiro 0644 to 0640. This can be overridden at compile time 12798121Sgshapiro by setting the DBMMODE macro. 12898121Sgshapiro SMRSH: Fix man page bug: replace SMRSH_CMDBIN with SMRSH_CMDDIR. 12998121Sgshapiro Problem noted by Dave Alden of Ohio State University. 13098121Sgshapiro VACATION: When listing the vacation database (-l), don't show 13198121Sgshapiro bogus timestamps for excluded (-x) addresses. Problem 13298121Sgshapiro noted by Bryan Costales. 13398121Sgshapiro New Files: 13498121Sgshapiro cf/mailer/cyrusv2.m4 13598121Sgshapiro 13694334Sgshapiro8.12.3/8.12.3 2002/04/05 13794334Sgshapiro NOTICE: In general queue files should not be moved if queue groups 13894334Sgshapiro are used. In previous versions this could cause mail 13994334Sgshapiro not to be delivered if a queue file is repeatedly moved 14094334Sgshapiro by an external process whenever sendmail moved it back 14194334Sgshapiro into the right place. Some precautions have been taken 14294334Sgshapiro to avoid moving queue files if not really necessary. 14394334Sgshapiro sendmail may use links to refer to queue files and it 14494334Sgshapiro may store the path of data files in queue files. Hence 14594334Sgshapiro queue files should not be moved unless those internals 14694334Sgshapiro are understood and the integrity of the files is not 14794334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 14894334Sgshapiro University. 14994334Sgshapiro If an error mail is created, and the mail is split across different 15094334Sgshapiro queue directories, and SuperSafe is off, then write the mail 15194334Sgshapiro to disk before splitting it, otherwise an assertion is 15294334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 15394334Sgshapiro of INTERMETA. 15494334Sgshapiro Fix possible race condition that could cause sendmail to forget 15594334Sgshapiro running queues. Problem noted by Jeff Wasilko of smoe.org. 15694334Sgshapiro Handle bogus qf files better without triggering assertions. 15794334Sgshapiro Problem noted by Guy Feltin. 15894334Sgshapiro Protect against interrupted select() call when enforcing Milter 15994334Sgshapiro read and write timeouts. Patch from Gurusamy Sarathy of 16094334Sgshapiro ActiveState. 16194334Sgshapiro Matching queue IDs with -qI should be case sensitive. Problem 16294334Sgshapiro noted by Anne Bennett of Concordia University. 16394334Sgshapiro If privileges have been dropped, don't try to change group ID to 16494334Sgshapiro the RunAsUser group. Problem noted by Neil Rickert of 16594334Sgshapiro Northern Illinois University. 16694334Sgshapiro Fix SafeFileEnvironment path munging when the specified path 16794334Sgshapiro contains a trailing slash. Based on patch from Dirk Meyer 16894334Sgshapiro of Dinoex. 16994334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 17094334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 17194334Sgshapiro Polytechnic Institute. 17294334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 17394334Sgshapiro if several mails are sent in one session and some of them 17494334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 17594334Sgshapiro Change timeout check such that cached information about a connection 17694334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 17794334Sgshapiro Based on patch from David Burns of Portland State University. 17894334Sgshapiro Properly count message size for mailstats during mail collection. 17994334Sgshapiro Problem noted by Werner Wiethege. 18094334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 18194334Sgshapiro patch from by Motonori Nakamura of Kyoto University. 18294334Sgshapiro Provide workaround for getopt() implementations that do not catch 18394334Sgshapiro missing arguments. 18494334Sgshapiro Fix the message size calculation if the message body is replaced by 18594334Sgshapiro a milter filter and buffered file I/O is being used. 18694334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 18794334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 18894334Sgshapiro Problem noted by Werner Wiethege. 18994334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 19094334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 19194334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 19294334Sgshapiro Properly deal with a case where sendmail is called by root running 19394334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 19494334Sgshapiro Lusky of ISS Atlanta. 19594334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 19694334Sgshapiro directories are used and mail is sent to a mailing list 19794334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 19894334Sgshapiro of Concordia University. 19994334Sgshapiro Fix class map parsing code if optional key is specified. Problem 20094334Sgshapiro found by Mario Nigrovic. 20194334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 20294334Sgshapiro incoming messages. A leading dot is always stripped by the 20394334Sgshapiro SMTP receiver regardless of whether or not it is followed by 20494334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 20594334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 20694334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 20794334Sgshapiro Elvers. 20894334Sgshapiro Correct the statistics gathered for total number of connections. 20994334Sgshapiro Instead of being the exact same number as the total number 21094334Sgshapiro of messages (T line in mailstats) it now represents the 21194334Sgshapiro total number of TCP connections. 21294334Sgshapiro Be more explicit about syntax errors in addresses, especially 21394334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 21494334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 21594334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 21694334Sgshapiro are used. Problem noted by Suresh Ramasubramanian. 21794334Sgshapiro Prevent a race condition on child cleanup for delivery to files. 21894334Sgshapiro Problem noted by Fletcher Mattox of the University of 21994334Sgshapiro Texas. 22094334Sgshapiro Change the SMTP error code for temporary map failures from 421 22194334Sgshapiro to 451. 22294334Sgshapiro Do not assume that realloc(NULL, size) works on all OS (this was 22394334Sgshapiro only done in one place: queue group creation). Based on 22494334Sgshapiro patch by Bryan Costales. 22594334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 22694334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 22794334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 22894334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 22994334Sgshapiro errors. By doing so, the host was marked as having a 23094334Sgshapiro temporary problem and other mail destined for that host was 23194334Sgshapiro queued for the next queue run. Problem noted by Fletcher 23294334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 23394334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 23494334Sgshapiro and Neil Rickert of Northern Illinois University. 23594334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 23694334Sgshapiro which drop the connection instead of responding to the 23794334Sgshapiro command). 23894334Sgshapiro Portability: 23994334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 24098121Sgshapiro available. 24194334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 24294334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 24394334Sgshapiro settings. Patch from Elias Halldor Agustsson of 24494334Sgshapiro Skyrr. 24594334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 24694334Sgshapiro noted by John Beck. 24794334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 24894334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 24994334Sgshapiro Rajesh Somasund of Hewlett-Packard. 25094334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 25194334Sgshapiro SMTP AUTH information. This feature was actually added in 25294334Sgshapiro 8.12.0 but a release note was not included. 25394334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 25494334Sgshapiro parameter is set and the LDAP lookup returns a temporary 25594334Sgshapiro error. 25694334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 25794334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 25894334Sgshapiro Krzysztof Oledzki. 25994334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 26094334Sgshapiro initialization as aliases are not needed for the MSP. 26194334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 26294334Sgshapiro is in use. Patch from Andrzej Filip. 26394334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 26494334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 26594334Sgshapiro This will only have an effect if a parameter is specified, 26694334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 26794334Sgshapiro it is embedded in square brackets. Problem noted by 26894334Sgshapiro Theo Van Dinter of Collective Technologies. 26994334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 27094334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 27194334Sgshapiro to allow for the proper time zone on systems where the 27294334Sgshapiro default results in misleading time stamps. That is, syslog 27394334Sgshapiro time stamps and Date headers on submitted mail will use the 27494334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 27594334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 27694334Sgshapiro by Neil Rickert of Northern Illinois University. 27794334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 27894334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 27994334Sgshapiro noted by John Beck. 28094334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 28194334Sgshapiro if queue groups are used. 28294334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 28394334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 28494334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 28594334Sgshapiro Suggested by Bryan Costales. 28694334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 28794334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 28894334Sgshapiro structure that is passed to xxfi_connect(). Notice: 28998121Sgshapiro this fix requires that sendmail and libmilter both have 29098121Sgshapiro this change; mixing versions may lead to wrong port 29194334Sgshapiro values depending on the endianness of the involved systems. 29294334Sgshapiro Problem noted by Gisle Aas of ActiveState. 29394334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 29494334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 29594334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 29694334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 29794334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 29894334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 29994334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 30094334Sgshapiro this to 1 if your LDAP client libraries include 30194334Sgshapiro ldap_memfree(). 30294334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 30394334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 30494334Sgshapiro SMRSH: Fix compilation problem on some operating systems. Problem 30594334Sgshapiro noted by Christian Krackowizer of schuler technodat GmbH. 30694334Sgshapiro VACATION: Allow root to operate on user vacation databases. Based 30794334Sgshapiro on patch from Greg Couch of the University of California, 30894334Sgshapiro San Francisco. 30994334Sgshapiro VACATION: Don't ignore -C option. Based on patch by Bryan Costales. 31094334Sgshapiro VACATION: Clarify option usage in the man page. Problem noted by 31194334Sgshapiro Joe Barbish. 31294334Sgshapiro New Files: 31394334Sgshapiro libmilter/docs/smfi_setbacklog.html 31494334Sgshapiro 31590792Sgshapiro8.12.2/8.12.2 2002/01/13 31690792Sgshapiro Don't complain too much if stdin, stdout, or stderr are missing 31790792Sgshapiro at startup, only log an error message. 31890792Sgshapiro Fix potential problem if an unknown operation mode (character 31990792Sgshapiro following -b) has been specified. 32090792Sgshapiro Prevent purgestat from looping even if someone changes the 32190792Sgshapiro permissions or owner of hoststatus files. Problem noted 32290792Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 32390792Sgshapiro Properly record dropped connections in persistent host status. 32490792Sgshapiro Problem noted by Ulrich Windl of the Universitat 32590792Sgshapiro Regensburg. 32690792Sgshapiro Remove newlines from recipients read via sendmail -t to prevent 32790792Sgshapiro SMTP protocol errors when sending the RCPT command. 32890792Sgshapiro Problem noted by William D.

Problem noted by Kari Hurtta of 33290792Sgshapiro the Finnish Meteorological Institute. 33390792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 33490792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 33590792Sgshapiro of the Finnish Meteorological Institute. 33690792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 33790792Sgshapiro needs to collect children status to avoid zombie processes. 33890792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 33990792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 34090792Sgshapiro commands are issued. This makes it consistent with normal 34190792Sgshapiro SMTP connections. 34290792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 34390792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 34490792Sgshapiro and Technology. 34590792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 34690792Sgshapiro message sender if the sender had used a deprecated RFC822 34790792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 34890792Sgshapiro Meteorological Institute. 34990792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 35090792Sgshapiro parsing. Problem noted by Jorg Bielak from Coastal Web 35190792Sgshapiro Online. 35290792Sgshapiro For systems on which stat(2) does not return a value for st_blksize 35390792Sgshapiro that is the "optimal blocksize for I/O" three new compile 35490792Sgshapiro time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF, 35590792Sgshapiro and SM_IO_MAX_BUF, which define an upper limit for 35690792Sgshapiro regular files, and a lower and upper limit for other file 35790792Sgshapiro types, respectively. 35890792Sgshapiro Fix a potential deadlock if two events are supposed to occur at 35990792Sgshapiro exactly the same time.

Problem noted by Bjoern Voigt of TU Berlin. 37790792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 37890792Sgshapiro server gets stuck while processing that command. Problem 37990792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 38090792Sgshapiro In addition to printing errors when parsing recipients during 38190792Sgshapiro command line invocations log them to make it simpler 38290792Sgshapiro to understand possible DSNs to postmaster. 38390792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 38490792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 38590792Sgshapiro instead of forcing localhost. 38690792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 38790792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 38890792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 38990792Sgshapiro noted by Neil Rickert of Northern Illinois University. 39090792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 39190792Sgshapiro dropping the connection during an SMTP transaction, stop 39290792Sgshapiro sending commands. This prevents bogus "Bad file number" 39390792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 39490792Sgshapiro Worcester Polytechnic Institute. 39590792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 39690792Sgshapiro almost always too small; do not guess the size at all. 39790792Sgshapiro New VENDOR_DEC for Compaq/DEC.

You need to create a new user and 54090792Sgshapiro a new group before installing sendmail (both called smmsp by 54190792Sgshapiro default). The installation process tries to install 54290792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 54390792Sgshapiro default.

Suggested 55490792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 55590792Sgshapiro (IdS). 55690792Sgshapiro Fixed problem of a global variable being used for a timeout jump 55790792Sgshapiro point where the variable could become overused for more than 55890792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 55990792Sgshapiro a corrupted stack causing a core dump. The timeout is now 56090792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 56190792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 56290792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 56390792Sgshapiro checks (group ID of RunAsUser). This allows use of a 56490792Sgshapiro set-group-ID sendmail binary for initial message submission 56590792Sgshapiro and no set-user-ID root sendmail is needed. For details 56690792Sgshapiro see sendmail/SECURITY. 56790792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 56890792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 56990792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 57090792Sgshapiro with a fallback of sendmail.cf as configuration file. See 57190792Sgshapiro sendmail/SECURITY. 57290792Sgshapiro New configuration file option UseMSP to allow group writable queue 57390792Sgshapiro files if the group is the same as that of a set-group-ID 57490792Sgshapiro sendmail binary. See sendmail/SECURITY. 57590792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 57690792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 57790792Sgshapiro is sendmail.cf (to be backward compatible). This selection 57890792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 57990792Sgshapiro file: client or mta). See sendmail/SECURITY. 58090792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 58190792Sgshapiro command has been removed. 58290792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 58390792Sgshapiro at compile time or per host (ruleset). 58490792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 58590792Sgshapiro used to look up local mail recipients; the default value 58690792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 58790792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 58890792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 58990792Sgshapiro long, to accomodate envelope splitting. File systems with 59090792Sgshapiro a 14 character file name length limit are no longer 59190792Sgshapiro supported. 59290792Sgshapiro Recipient list used for delivery now gets internally ordered by 59390792Sgshapiro hostsignature (character string version of MX RR). This orders 59490792Sgshapiro recipients for the same MX RR's together meaning smaller 59590792Sgshapiro portions of the list need to be scanned (instead of the whole 59690792Sgshapiro list) each delivery() pass to determine piggybacking. The 59790792Sgshapiro significance of the change is better the larger the recipient 59890792Sgshapiro list. Hostsignature is now created during recipient list 59990792Sgshapiro creation rather than just before delivery. 60090792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 60190792Sgshapiro piggybacking (called coincidental) extended to coattail 60290792Sgshapiro piggybacking. Rather than complete MX RR matching 60390792Sgshapiro (coincidental) piggybacking is done if just the lowest value 60490792Sgshapiro preference matches (coattail). 60590792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 60690792Sgshapiro try other MX hosts if available. 60790792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 60890792Sgshapiro outgoing (client-side) SMTP Authentication. 60990792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 61090792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 61190792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 61290792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 61390792Sgshapiro A new ruleset authinfo can be used to return client side 61490792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 61590792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 61690792Sgshapiro removed in future versions. 61790792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 61890792Sgshapiro requires 334. Mercury 1.48 is a known offender. 61990792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 62090792Sgshapiro for the security layer in SMTP AUTH (SASL). See 62190792Sgshapiro doc/op/op.me for details. 62290792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 62390792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 62490792Sgshapiro signed the presented certificate, the CN and the MD5 hash 62590792Sgshapiro of the presented certificate, respectively. 62690792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 62790792Sgshapiro New ruleset srv_features to enable/disable certain features in the 62890792Sgshapiro server per connection. See doc/op/op.me for details. 62990792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 63090792Sgshapiro recipient; useful to decide whether a conection is secure 63190792Sgshapiro enough on a per recipient basis. 63290792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 63390792Sgshapiro for STARTTLS. 63490792Sgshapiro If no certificate has been requested, the macro {verify} has the 63590792Sgshapiro value "NOT". 63690792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 63790792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 63890792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 63990792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 64090792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 64190792Sgshapiro really required. This change results in a noticable 64290792Sgshapiro performance gains on most machines. Moreover, if shared 64390792Sgshapiro memory is in use, reuse the key several times. 64490792Sgshapiro Add queue groups which can be used to group queue directories with 64590792Sgshapiro the same behavior together. See doc/op/op.me for details. 64690792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 64790792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 64890792Sgshapiro are initially sorted which may result in faster envelope 64990792Sgshapiro splitting. If the mail is submitted directly from the 65090792Sgshapiro command line, then the value also limits the number of 65190792Sgshapiro processes to deliver the envelopes; if more envelopes are 65290792Sgshapiro created they are only queued up and must be taken care of 65390792Sgshapiro by a queue run. 65490792Sgshapiro The check for 'enough disk space' now pays attention to which file 65590792Sgshapiro system each queue directory resides in. 65690792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 65790792Sgshapiro New option QueueFileMode for the default permissions of queue files. 65890792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 65990792Sgshapiro group (one or more queues in a multi-queue environment 66090792Sgshapiro collected together) to process the same work list at the 66190792Sgshapiro same time. 66290792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 66390792Sgshapiro active queue runner processes. 66490792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 66590792Sgshapiro runners per queue group. 66690792Sgshapiro Queue member selection by substring pattern matching now allows 66790792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 66890792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 66990792Sgshapiro of the queue that match during processing. 67090792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 67190792Sgshapiro periodically forking a child to process the queue, a single 67290792Sgshapiro child is forked for each queue that sleeps between queue 67390792Sgshapiro runs. A SIGHUP signal can be sent to restart this 67490792Sgshapiro persistent queue runner. 67590792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 67690792Sgshapiro sendmail process which only runs the queue at an interval: 67790792Sgshapiro sendmail -q15m). 67890792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 67990792Sgshapiro Proposed by Thom O'Connor. 68090792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 68190792Sgshapiro unless the new -qf option or -v is used. 68290792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 68390792Sgshapiro several queue runners are started by hand to avoid contention. 68490792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 68590792Sgshapiro of the qf file (older entries first). 68690792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 68790792Sgshapiro a client to specify an amount of time within which an e-mail 68890792Sgshapiro should be delivered. New option DeliverByMin added to set the 68990792Sgshapiro minimum amount of time or disable the extension. 69090792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 69190792Sgshapiro not allowed unless escaped or quoted. 69290792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 69390792Sgshapiro by Leif Johansson of Stockholm University, which was based on 69490792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 69590792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 69690792Sgshapiro Technology, Stockholm, Sweden. 69790792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 69890792Sgshapiro behavior (no MX lookups), put the name in square brackets. 69990792Sgshapiro Proposed by Thom O'Connor. 70090792Sgshapiro Use shared memory to store free space of filesystems that are used 70190792Sgshapiro for queues, if shared memory is available and if a key is set 70290792Sgshapiro via SharedMemoryKey. This minimizes the number of system 70390792Sgshapiro calls to check the available space. See doc/op/op.me for 70490792Sgshapiro details. 70590792Sgshapiro If shared memory is compiled in the option -bP can be used to print 70690792Sgshapiro the number of entries in the queue(s). 70790792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 70890792Sgshapiro and the usual documentation for details. 70990792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 71090792Sgshapiro Remove '-U' (initial user submission) command line option as 71190792Sgshapiro announced in 8.10. 71290792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 71390792Sgshapiro New macro {addr_type} which contains whether the current address is 71490792Sgshapiro an envelope sender or recipient address. Suggested by 71590792Sgshapiro Neil Rickert of Northern Illinois University. 71690792Sgshapiro Two new options for host maps: -d (retransmission timeout), 71790792Sgshapiro -r (number of retries). 71890792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 71990792Sgshapiro separator such that a lookup can return both an attribute 72090792Sgshapiro and value separated by the given separator. 72190792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 72290792Sgshapiro to map class arith. 72390792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 72490792Sgshapiro (errors that occur when sending an error message) are dropped. 72590792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 72690792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 72790792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 72890792Sgshapiro requirements for files containing secret keys. This is 72990792Sgshapiro necessary for the MSP if client authentification is used. 73090792Sgshapiro Properly handle quoted filenames for class files (to allow for 73190792Sgshapiro filenames with spaces). 73290792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 73390792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 73490792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 73590792Sgshapiro {if_addr_out} address of interface of outgoing connection. 73690792Sgshapiro {if_family_out} family of interface of outgoing connection. 73790792Sgshapiro The latter two are only set if the interface does not belong 73890792Sgshapiro to the loopback net. 73990792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 74090792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 74190792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 74290792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 74390792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 74490792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 74590792Sgshapiro all connections for a single delivery attempt to succeed. 74690792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 74790792Sgshapiro a threshold number of recipients has been rejected (option 74890792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 74990792Sgshapiro Development Group. 75090792Sgshapiro New option DelayLA to delay connections if the load averages 75190792Sgshapiro exceeds the specified value. The default of 0 does not 75290792Sgshapiro change the previous behavior. A value greater than 0 75390792Sgshapiro will cause sendmail to sleep for one second on most 75490792Sgshapiro SMTP commands and before accepting connections if that 75590792Sgshapiro load average is exceeded. 75690792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 75790792Sgshapiro recipients that are sent during a connection to a mailer. 75890792Sgshapiro This also introduces a new mailer field 'r' which defines 75990792Sgshapiro the maximum number of recipients (defaults to 100). 76090792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 76190792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 76290792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 76390792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 76490792Sgshapiro instead. 76590792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 76690792Sgshapiro builtin mailer pathnames. Use TCP instead. 76790792Sgshapiro PH map code updated to use the new libphclient API instead of the 76890792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 76990792Sgshapiro University of Illinois at Urbana-Champaign. 77090792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 77190792Sgshapiro for direct (command line) submissions. 77290792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 77390792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 77490792Sgshapiro Hagino of the KAME Project. 77590792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 77690792Sgshapiro whose content is rewritten similar to Reply-To:. 77790792Sgshapiro Proposed by Andrzej Filip. 77890792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 77990792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 78090792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 78190792Sgshapiro AUTH/STARTTLS related logfile entries. 78290792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 78390792Sgshapiro before logging. 78490792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 78590792Sgshapiro (at LogLevel 9/10 or higher). 78690792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 78790792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 78890792Sgshapiro in which most commands are rejected due to check_relay or 78990792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 79090792Sgshapiro Change logging format for cloned envelopes to be similar to that for 79190792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 79290792Sgshapiro of the Universitat Regensburg. 79390792Sgshapiro Added libsm, a C library of general purpose abstractions including 79490792Sgshapiro assertions, tracing and debugging with named debug categories, 79590792Sgshapiro exception handling, malloc debugging, resource pools, 79690792Sgshapiro portability abstractions, and an extensible buffered I/O 79790792Sgshapiro package. It will at some point replace libsmutil. 79890792Sgshapiro See libsm/index.html for details. 79990792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 80090792Sgshapiro care of by fork() and exit(). 80190792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 80290792Sgshapiro more consistent portablity amongst different platforms 80390792Sgshapiro new and old (from new libsm). 80490792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 80590792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 80690792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 80790792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 80890792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 80990792Sgshapiro synchronizations calls. 81090792Sgshapiro Add per-recipient status information to mailq -v output. 81190792Sgshapiro T_ANY queries are no longer used by sendmail. 81290792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 81390792Sgshapiro too (see include/sm/cdefs.h for more info). 81490792Sgshapiro sendmail -d now has general support for named debug categories. 81590792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 81690792Sgshapiro for details. 81790792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 81890792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 81990792Sgshapiro generated by this condition were illegal (not RFC conform). 82090792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 82190792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 82290792Sgshapiro mailer and the recipient has hence been rejected during the 82390792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 82490792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 82590792Sgshapiro that do not have postmaster defined. If an email was sent 82690792Sgshapiro from an address to which a DSN cannot be returned and 82790792Sgshapiro in which at least one recipient address is non-deliverable, 82890792Sgshapiro then that email had been delivered in each queue run. 82990792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 83090792Sgshapiro degli Studi dell'Insubria. 83190792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 83290792Sgshapiro i.e., the corresponding code is always compiled in now. 83390792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 83490792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 83590792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 83690792Sgshapiro attempting to canonify a hostname, some broken nameservers 83790792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 83890792Sgshapiro lookups. If you want to excuse this behavior, use this new 83990792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 84090792Sgshapiro Mark Roth of the University of Illinois at 84190792Sgshapiro Urbana-Champaign. 84290792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 84390792Sgshapiro noted by Joy Latten of IBM. 84490792Sgshapiro ConnectionRateThrottle limits the number of connections per second 84590792Sgshapiro to each daemon individually, not the overall number of 84690792Sgshapiro connections. 84790792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 84890792Sgshapiro sendmail to use a default alias schema as outlined in the 84990792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 85090792Sgshapiro cf/README. 85190792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 85290792Sgshapiro the first character after the class name is not a '/' or a 85390792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 85490792Sgshapiro rest of the line will be parsed as a map lookup. This 85590792Sgshapiro allows classes to be filled via a map lookup. See op.me 85690792Sgshapiro for more syntax information. Specifically, this can be 85790792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 85890792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 85990792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 86090792Sgshapiro example). 86190792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 86290792Sgshapiro the default schema used in the above two items. 86390792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 86490792Sgshapiro warning if a program being run from a mailer or file class 86590792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 86690792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 86790792Sgshapiro if a program being run from a mailer or file class 86890792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 86990792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 87090792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 87190792Sgshapiro (without quotes) will disable this and return to the 87290792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 87390792Sgshapiro Suggested by Bryan Stansell of GNAC. 87490792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 87590792Sgshapiro HELO/EHLO commands. 87690792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 87790792Sgshapiro possible protocol family which may be used for outgoing 87890792Sgshapiro connections. Restrictions placed on one family only affect 87990792Sgshapiro outgoing connections on that particular family. Because of 88090792Sgshapiro this change, the ${client_flags} macro is not set until the 88190792Sgshapiro connection is established. Based on patch from Motonori 88290792Sgshapiro Nakamura of Kyoto University. 88390792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 88490792Sgshapiro when the -bv option is given by users who are neither root 88590792Sgshapiro nor the TrustedUser so users can not read private aliases, 88690792Sgshapiro forwards, or :include: files. It also will override the -v 88790792Sgshapiro (verbose) command line option. 88890792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 88990792Sgshapiro address can't be used for the outgoing connection, fall 89090792Sgshapiro back to the settings in ClientPortOptions (if set). 89190792Sgshapiro Problem noted by John Beck of Sun Microsystems. 89290792Sgshapiro New named config file rule check_data for DATA command (input: 89390792Sgshapiro number of recipients). Based on patch from Mark Roth of 89490792Sgshapiro the University of Illinois at Urbana-Champaign. 89590792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 89690792Sgshapiro can be specified using the '#' option character. For 89790792Sgshapiro example, 'ETRN #queuegroup'. 89890792Sgshapiro If an LDAP server times out or becomes unavailable, close the 89990792Sgshapiro current connection and reopen to get to one of the fallback 90090792Sgshapiro servers. Patch from Paul Hilchey of the University of 90190792Sgshapiro British Columbia. 90290792Sgshapiro Make default error number on $#error messages 550 instead of 501 90390792Sgshapiro because 501 is not allowed on all commands. 90490792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 90590792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 90690792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 90790792Sgshapiro if required. 90890792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 90990792Sgshapiro class instead. 91090792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 91190792Sgshapiro "IPv6:" tag to identify the address properly. For example, 91290792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 91390792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 91490792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 91590792Sgshapiro MTA is running. For example, during a queue run. 91690792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 91790792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 91890792Sgshapiro Nelson of IBM. 91990792Sgshapiro The maximum number of commands before the MTA slows down when too 92090792Sgshapiro many "light weight" commands have been received are now 92190792Sgshapiro configurable during compile time. The current values and 92290792Sgshapiro their defaults are: 92390792Sgshapiro MAXBADCOMMANDS 25 unknown commands 92490792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 92590792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 92690792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 92790792Sgshapiro MAXETRNCOMMANDS 8 ETRN 92890792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 92990792Sgshapiro Costales of SL3D, Inc. 93090792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 93190792Sgshapiro ${MyMacro} is defined but also that it is not empty. 93290792Sgshapiro Properly quote usernames with special characters if they are used 93390792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 93490792Sgshapiro Meteorological Institute. 93590792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 93690792Sgshapiro messages for messages for mailing list expanded addresses 93790792Sgshapiro which are not delivered on the initial attempt. 93890792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 93990792Sgshapiro the final dot has been sent to avoid affecting future 94090792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 94190792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 94290792Sgshapiro file systems that require to call fsync() for a directory 94390792Sgshapiro if the meta-data in it has been changed. This should be 94490792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 94590792Sgshapiro See sendmail/README for further information. 94690792Sgshapiro Avoid file locking deadlock when updating the statistics file if 94790792Sgshapiro sendmail is signaled to terminate. Problem noted by 94890792Sgshapiro Christophe Wolfhugel of France Telecom. 94990792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 95090792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 95190792Sgshapiro the Finnish Meteorological Institute. 95290792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 95390792Sgshapiro from Peter A. Friend of EarthLink. 95490792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 95590792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 95690792Sgshapiro flora.ca. 95790792Sgshapiro Portability: 95890792Sgshapiro Remove support for AIX 2, which supports only 14 character 95990792Sgshapiro filenames and is outdated anyway. Suggested by 96090792Sgshapiro Valdis Kletnieks of Virginia Tech. 96190792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 96290792Sgshapiro i.e., use default /usr/sbin, change owner/group 96390792Sgshapiro of man pages and user-executable to root/sys, set 96490792Sgshapiro optimization limit to 0 (unlimited). Based on patch 96590792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 96690792Sgshapiro Hurtta of the Finnish Meteorological Institute. 96790792Sgshapiro Do not assume LDAP support is installed by default under 96890792Sgshapiro Solaris 8 and later. 96990792Sgshapiro Add support for OpenUNIX. 97090792Sgshapiro CONFIG: Increment version number of config file to 10. 97190792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 97290792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 97390792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 97490792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 97590792Sgshapiro temporary lookup failures. 97690792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 97790792Sgshapiro action to be taken by aborting the search for domain names 97890792Sgshapiro or IP nets. 97990792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 98090792Sgshapiro relay address as long as the other part allows the email 98190792Sgshapiro to get through. 98290792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 98390792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 98490792Sgshapiro entry like user+*@domain. This allows handling of details by 98590792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 98690792Sgshapiro introduced to match only non-empty details of addresses. 98790792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 98890792Sgshapiro and hence there is no required order within the MAILER 98990792Sgshapiro section anymore except for MAILER(`uucp') which must come 99090792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 99190792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 99290792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 99390792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 99490792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 99590792Sgshapiro in the access map which returns OK or RELAY actually 99690792Sgshapiro terminates check_* ruleset checking. 99790792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 99890792Sgshapiro tls_rcpt, see cf/README for details. 99990792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 100090792Sgshapiro STARTTLS has been used to "(version=${tls_version} 100190792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 100290792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 100390792Sgshapiro options friends/haters instead of "To:" and enable 100490792Sgshapiro specification of whole domains instead of just users. 100590792Sgshapiro Notice: this change is not backward compatible. 100690792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 100790792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 100890792Sgshapiro cf/README for details. 100990792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 101090792Sgshapiro the access map. Proposed by Randall Winchester of the 101190792Sgshapiro University of Maryland. 101290792Sgshapiro CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for 101390792Sgshapiro the local mailer. Proposed by Ingo Brueckl of Wupper Online. 101490792Sgshapiro CONFIG: confRELAY_MSG/confREJECT_MSG can override the default 101590792Sgshapiro messages for an unauthorized relaying attempt/for access 101690792Sgshapiro map entries with RHS REJECT, respectively. 101790792Sgshapiro CONFIG: FEATURE(`always_add_domain') takes an optional argument 101890792Sgshapiro to specify another domain to be added instead of the local one. 101990792Sgshapiro Suggested by Richard H. Gumpertz of Computer Problem 102090792Sgshapiro Solving. 102190792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 102290792Sgshapiro options, see doc/op/op.me for details. 102390792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 102490792Sgshapiro the security layer in SMTP AUTH (SASL). 102590792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 102690792Sgshapiro immediately. 102790792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 102890792Sgshapiro allows checking of the return values of the DNS lookups. 102990792Sgshapiro See cf/README for details. 103090792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 103190792Sgshapiro temporary lookup failures. 103290792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 103390792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 103490792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 103590792Sgshapiro memory use. 103690792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 103790792Sgshapiro of the sender and the recipient address delimited by the 103890792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 103990792Sgshapiro in the access map. Based on code contributed by Mathias 104090792Sgshapiro Koerber of Singapore Telecommunications Ltd. 104190792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 104290792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 104390792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 104490792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 104590792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 104690792Sgshapiro the recipient host if LUSER_RELAY is used. 104790792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 104890792Sgshapiro +detail portion of the address when passing address to 104990792Sgshapiro local delivery agent. Disables alias and .forward +detail 105090792Sgshapiro stripping. Only use if LDA supports this. 105190792Sgshapiro CONFIG: Removed deprecated FEATURE(`rbl'). 105290792Sgshapiro CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() 105390792Sgshapiro which allow you to specify 'equivalent' hosts for LDAP 105490792Sgshapiro Routing lookups. Equivalent hostnames are replaced by the 105590792Sgshapiro masquerade domain name for lookups. See cf/README for 105690792Sgshapiro additional details. 105790792Sgshapiro CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which 105890792Sgshapiro instructs the rulesets on what to do if the address being 105990792Sgshapiro looked up has +detail information. See cf/README for more 106090792Sgshapiro information. 106190792Sgshapiro CONFIG: When chosing a new destination via LDAP Routing, also look 106290792Sgshapiro up the new routing address/host in the mailertable. Based 106390792Sgshapiro on patch from Don Badrak of the United States Census Bureau. 106490792Sgshapiro CONFIG: Do not reject the SMTP Mail from: command if LDAP Routing 106590792Sgshapiro is in use and the bounce option is enabled. Only reject 106690792Sgshapiro recipients as user unknown. 106790792Sgshapiro CONFIG: Provide LDAP support for the remaining database map 106890792Sgshapiro features. See the ``USING LDAP FOR ALIASES AND MAPS'' 106990792Sgshapiro section of cf/README for more information. 107090792Sgshapiro CONFIG: Add confLDAP_CLUSTER which defines the ${sendmailMTACluster} 107190792Sgshapiro macro used for LDAP searches as described above in ``USING 107290792Sgshapiro LDAP FOR ALIASES, MAPS, AND CLASSES''. 107390792Sgshapiro CONFIG: confCLIENT_OPTIONS has been replaced by CLIENT_OPTIONS(), 107490792Sgshapiro which takes the options as argument and can be used 107590792Sgshapiro multiple times; see cf/README for details. 107690792Sgshapiro CONFIG: Add configuration macros for new options: 107790792Sgshapiro confBAD_RCPT_THROTTLE BadRcptThrottle 107890792Sgshapiro confDIRECT_SUBMISSION_MODIFIERS DirectSubmissionModifiers 107990792Sgshapiro confMAILBOX_DATABASE MailboxDatabase 108090792Sgshapiro confMAX_QUEUE_CHILDREN MaxQueueChildren 108190792Sgshapiro confMAX_RUNNERS_PER_QUEUE MaxRunnersPerQueue 108290792Sgshapiro confNICE_QUEUE_RUN NiceQueueRun 108390792Sgshapiro confQUEUE_FILE_MODE QueueFileMode 108490792Sgshapiro confFAST_SPLIT FastSplit 108590792Sgshapiro confTLS_SRV_OPTIONS TLSSrvOptions 108690792Sgshapiro See above (and related documentation) for further information. 108790792Sgshapiro CONFIG: Add configuration variables for new timeout options: 108890792Sgshapiro confTO_ACONNECT Timeout.aconnect 108990792Sgshapiro confTO_AUTH Timeout.auth 109090792Sgshapiro confTO_LHLO Timeout.lhlo 109190792Sgshapiro confTO_STARTTLS Timeout.starttls 109290792Sgshapiro CONFIG: Add configuration macros for mail filter API: 109390792Sgshapiro confINPUT_MAIL_FILTERS InputMailFilters 109490792Sgshapiro confMILTER_LOG_LEVEL Milter.LogLevel 109590792Sgshapiro confMILTER_MACROS_CONNECT Milter.macros.connect 109690792Sgshapiro confMILTER_MACROS_HELO Milter.macros.helo 109790792Sgshapiro confMILTER_MACROS_ENVFROM Milter.macros.envfrom 109890792Sgshapiro confMILTER_MACROS_ENVRCPT Milter.macros.envrcpt 109990792Sgshapiro Mail filters can be defined via INPUT_MAIL_FILTER() and 110090792Sgshapiro MAIL_FILTER().

New option -D mbdb specifies the 113690792Sgshapiro mailbox database type. 113790792Sgshapiro MAIL.LOCAL: New option "-h filename" which instructs mail.local to 113890792Sgshapiro deliver the mail to the named file in the user's home 113990792Sgshapiro directory instead of the system mail spool area. Based on 114090792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 114190792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 114290792Sgshapiro doesn't truncate the statistics file. 114390792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 114490792Sgshapiro instead of white space. 114590792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 114690792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 114790792Sgshapiro Meteorological Institute. 114890792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 114990792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 115090792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 115190792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 115290792Sgshapiro instead of syslog. 115390792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 115490792Sgshapiro in the password file. The -f and -m options must be used 115590792Sgshapiro to specify the database and message file since there is no 115690792Sgshapiro home directory for the default settings for these options. 115790792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 115890792Sgshapiro local mail recipients; it reads the MailboxDatabase option 115990792Sgshapiro from the sendmail.cf file. New option -C cffile which 116090792Sgshapiro specifies the path of the sendmail.cf file. 116190792Sgshapiro New Directories: 116290792Sgshapiro libmilter/docs 116390792Sgshapiro New Files: 116490792Sgshapiro cf/cf/README 116590792Sgshapiro cf/cf/submit.cf 116690792Sgshapiro cf/cf/submit.mc 116790792Sgshapiro cf/feature/authinfo.m4 116890792Sgshapiro cf/feature/compat_check.m4 116990792Sgshapiro cf/feature/enhdnsbl.m4 117090792Sgshapiro cf/feature/msp.m4 117190792Sgshapiro cf/feature/local_no_masquerade.m4 117290792Sgshapiro cf/feature/lookupdotdomain.m4 117390792Sgshapiro cf/feature/preserve_luser_host.m4 117490792Sgshapiro cf/feature/preserve_local_plus_detail.m4 117590792Sgshapiro cf/feature/queuegroup.m4 117690792Sgshapiro cf/sendmail.schema 117790792Sgshapiro contrib/dnsblaccess.m4 117890792Sgshapiro devtools/M4/UNIX/sm-test.m4 117990792Sgshapiro devtools/OS/OpenUNIX.5.i386 118090792Sgshapiro editmap/* 118190792Sgshapiro include/sm/* 118290792Sgshapiro libsm/* 118390792Sgshapiro libsmutil/cf.c 118490792Sgshapiro libsmutil/err.c 118590792Sgshapiro sendmail/SECURITY 118690792Sgshapiro sendmail/TUNING 118790792Sgshapiro sendmail/bf.c 118890792Sgshapiro sendmail/bf.h 118990792Sgshapiro sendmail/sasl.c 119090792Sgshapiro sendmail/sm_resolve.c 119190792Sgshapiro sendmail/sm_resolve.h 119290792Sgshapiro sendmail/tls.c 119390792Sgshapiro Deleted Files: 119490792Sgshapiro cf/feature/rbl.m4 119590792Sgshapiro cf/ostype/aix2.m4 119690792Sgshapiro devtools/OS/AIX.2 119790792Sgshapiro include/sendmail/cdefs.h 119890792Sgshapiro include/sendmail/errstring.h 119990792Sgshapiro include/sendmail/useful.h 120090792Sgshapiro libsmutil/errstring.c 120190792Sgshapiro sendmail/bf_portable.c 120290792Sgshapiro sendmail/bf_portable.h 120390792Sgshapiro sendmail/bf_torek.c 120490792Sgshapiro sendmail/bf_torek.h 120590792Sgshapiro sendmail/clock.c 120690792Sgshapiro Renamed Files: 120790792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 120890792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 120990792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 121090792Sgshapiro 121182017Sgshapiro8.11.6/8.11.6 2001/08/20 121282017Sgshapiro SECURITY: Fix a possible memory access violation when specifying 121382017Sgshapiro out-of-bounds debug parameters.

Problem noted by Damian Kuczynski of NIK. 162266494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 162366494Sgshapiro makemap to 'unmake' the map. 162466494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 162566494Sgshapiro sendmail. 162666494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 162766494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 162866494Sgshapiro Meteorological Institute. 162966494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 163066494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 163166494Sgshapiro dot as the only character on the line. 163266494Sgshapiro New Files: 163366494Sgshapiro cf/ostype/solaris8.m4 163466494Sgshapiro 163564562Sgshapiro8.11.0/8.11.0 2000/07/19 163664562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 163764562Sgshapiro (not the normal case), some operating systems will still 163864562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 163964562Sgshapiro to drop all of its privileges. If sendmail needs to drop 164064562Sgshapiro these privileges and the operating system doesn't set the 164164562Sgshapiro saved-uid as well, exit with an error. Problem noted by 164264562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 164364562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 164464562Sgshapiro it populates. It is possible that some broken 164564562Sgshapiro implementations of snprintf() exist that do not do this. 164664562Sgshapiro Systems in this category should compile with 164764562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 164864562Sgshapiro system and report broken implementations to 164964562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 165064562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 165164562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 165264562Sgshapiro Implementation influenced by the example programs of 165364562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 165464562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 165564562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 165664562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 165764562Sgshapiro cf/README and doc/op/op.*. 165864562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 165964562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 166064562Sgshapiro ${server_name}, and ${server_addr}. These are documented 166164562Sgshapiro in cf/README and doc/op/op.*. 166264562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 166364562Sgshapiro random data. 166464562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 166564562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 166664562Sgshapiro try to use STARTTLS despite the security problems. 166764562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 166864562Sgshapiro support encryption. Based on code contributed by Tim 166964562Sgshapiro Martin of CMU. 167064562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 167164562Sgshapiro strength factor. 167264562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 167364562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 167464562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 167564562Sgshapiro of CMU. 167664562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 167764562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 167864562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 167964562Sgshapiro Fix the default family selection for DaemonPortOptions. As 168064562Sgshapiro documented, unless a family is specified in a 168164562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 168264562Sgshapiro also the default if no DaemonPortOptions value is set. 168364562Sgshapiro Therefore, IPv6 users should configure additional sockets 168464562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 168564562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 168664562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 168764562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 168864562Sgshapiro the interface information for an outgoing connection. 168964562Sgshapiro Not doing so was creating a mismatch between the socket 169064562Sgshapiro family and address used in subsequent connections if the 169164562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 169264562Sgshapiro by John Beck of Sun Microsystems. 169364562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 169464562Sgshapiro family based on the IP address. ${if_family} is no longer 169564562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 169664562Sgshapiro of Sun Microsystems. 169764562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 169864562Sgshapiro macros for both the incoming interface address/family and 169964562Sgshapiro the outgoing interface address/family. In order for M=b 170064562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 170164562Sgshapiro the incoming information in the queue file for later 170264562Sgshapiro delivery attempts. 170364562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 170464562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 170564562Sgshapiro smoe.org. 170664562Sgshapiro Add more vigilance in checking for putc() errors on output streams 170764562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 170864562Sgshapiro noted by Graeme Hewson of Oracle. 170964562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 171064562Sgshapiro Problem noted by Ajay Matia. 171164562Sgshapiro Under certain circumstances, an address could be listed as deferred 171264562Sgshapiro but would be bounced back to the sender as failed to be 171364562Sgshapiro delivered when it really should have been queued. Problem 171464562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 171564562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 171664562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 171764562Sgshapiro Hedeland of Ericsson. 171864562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 171964562Sgshapiro is defined to avoid a core dump due to incompatibilities 172064562Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 172164562Sgshapiro of Northern Illinois University. 172264562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 172364562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 172464562Sgshapiro Convert the free disk space shown in a control socket status query 172564562Sgshapiro to kilobyte units. 172664562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 172764562Sgshapiro looking up the hostname, requeue the message for a later 172864562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 172964562Sgshapiro Polytechnic. 173064562Sgshapiro Under the proper circumstances, failed connections would be recorded 173164562Sgshapiro as "Bad file number" instead of "Connection failed" in the 173264562Sgshapiro queue file and persistent host status. Problem noted by 173364562Sgshapiro Graeme Hewson of Oracle. 173464562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 173564562Sgshapiro within the hoststatus directory (e.g., lost+found). 173664562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 173764562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 173864562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 173964562Sgshapiro If a message data file can't be opened at delivery time, panic and 174064562Sgshapiro abort the attempt instead of delivering a message that 174164562Sgshapiro states "<<< No Message Collected >>>". 174264562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 174364562Sgshapiro restrictive. Problem noted by Mark G. Thomas of Mark 174464562Sgshapiro G. Thomas Consulting. 174564562Sgshapiro Preserve source port number instead of replacing it with the ident 174664562Sgshapiro port number (113). 174764562Sgshapiro Document the queue status characters in the mailq man page. 174864562Sgshapiro Suggested by Ulrich Windl of the Universitat Regensburg. 174964562Sgshapiro Process queued items in which none of the recipient addresses have 175064562Sgshapiro host portions (or there are no recipients). Problem noted 175164562Sgshapiro by Valdis Kletnieks of Virginia Tech. 175264562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 175364562Sgshapiro only the first to open the connection is allowed to close 175464562Sgshapiro it so a later map close doesn't break the connection for 175564562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 175664562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 175764562Sgshapiro authentication. Patch from Rainer Schoepf of the 175864562Sgshapiro University of Mainz. 175964562Sgshapiro Provide workaround for inconsistent handling of data passed 176064562Sgshapiro via callbacks to Cyrus SASL prior to version 1.5.23. 176164562Sgshapiro Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.

From Jun 176664562Sgshapiro Kuriyama of IMG SRC, Inc. and the FreeBSD Project. 176764562Sgshapiro Replace code for finding the number of CPUs on HPUX. 176864562Sgshapiro NCRUNIX MP-RAS 3.02 SO_REUSEADDR socket option does not 176964562Sgshapiro work properly causing problems if the accept() 177064562Sgshapiro fails and the socket needs to be reopened. Patch 177164562Sgshapiro from Tom Moore of NCR. 177264562Sgshapiro NetBSD uses a .0 extension of formatted man pages. From 177366494Sgshapiro Andrew Brown of Crossbar Security. 177464562Sgshapiro Return to using the IPv6 AI_DEFAULT flag instead of AI_V4MAPPED 177564562Sgshapiro for calls to getipnodebyname(). The Linux 177664562Sgshapiro implementation is broken so AI_ADDRCONFIG is stripped 177764562Sgshapiro under Linux.

Problem noted 202064562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 202164562Sgshapiro (IdS). 202264562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 202364562Sgshapiro a large number of files. See cf/README for more details. 202464562Sgshapiro The directory structure of the distribution has changed slightly 202564562Sgshapiro for easier code sharing among the programs. 202664562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 202764562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 202864562Sgshapiro which hold the client's authentication credentials, 202964562Sgshapiro the mechanism used for authentication, and the 203064562Sgshapiro authorization identity (i.e., the AUTH= parameter if 203164562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 203264562Sgshapiro On systems which use the Torek stdio library (all of the BSD 203364562Sgshapiro distributions), use memory-buffered files to reduce 203464562Sgshapiro file system overhead by not creating temporary files on 203564562Sgshapiro disk. Contributed by Exactis.com, Inc. 203664562Sgshapiro New option DataFileBufferSize to control the maximum size of a 203764562Sgshapiro memory-buffered data (df) file before a disk-based file is 203864562Sgshapiro used.

Contributed by Exactis.com, Inc. 204264562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 204364562Sgshapiro now listen on several different ports. Use: 204464562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 204564562Sgshapiro to run a Message Submission Agent (MSA); this is turned 204664562Sgshapiro on by default in m4-generated .cf files; it can be turned 204764562Sgshapiro off with FEATURE(`no_default_msa'). 204864562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 204964562Sgshapiro begin using RFC 2476 Message Submission for initial user 205064562Sgshapiro message submission. XUSR may disappear from a future release. 205164562Sgshapiro The new '-G' (relay (gateway) submission) command line option 205264562Sgshapiro indicates that the message being submitted from the command 205364562Sgshapiro line is for relaying, not initial submission. This means 205464562Sgshapiro the message will be rejected if the addresses are not fully 205564562Sgshapiro qualified and no canonicalization will be done. Future 205664562Sgshapiro releases may even reject improperly formed messages. 205764562Sgshapiro The '-U' (initial user submission) command line option is 205864562Sgshapiro deprecated and may be removed from a future release. 205964562Sgshapiro Mail user agents should begin using '-G' to indicate that 206064562Sgshapiro this is a relay submission (the inverse of -U). 206164562Sgshapiro The next release of sendmail will assume that any message submitted 206264562Sgshapiro from the command line is an initial user submission and act 206364562Sgshapiro accordingly. 206464562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 206564562Sgshapiro program or deliver to file as the owner of that file, the 206664562Sgshapiro address is marked as unsafe. This means if RunAsUser is 206764562Sgshapiro set, users won't be able to use programs or delivery to 206864562Sgshapiro files in their .forward files. Administrators can override 206964562Sgshapiro this by setting the DontBlameSendmail option to the new 207064562Sgshapiro setting NonRootSafeAddr. 207164562Sgshapiro Allow group or world writable directories if the sticky bit is set 207264562Sgshapiro on the directory and DontBlameSendmail is set to 207364562Sgshapiro TrustStickyBit.

To use multiple queues, supply 210664562Sgshapiro a QueueDirectory option value ending with an asterisk. For 210764562Sgshapiro example, /var/spool/mqueue/q* will use all of the 210864562Sgshapiro directories or symbolic links to directories beginning with 210964562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 211064562Sgshapiro mind, the queue directory structure should not be changed 211164562Sgshapiro while sendmail is running. Queue runs create a separate 211264562Sgshapiro process for running each queue unless the verbose flag is 211364562Sgshapiro given on a non-daemon queue run. New items are randomly 211464562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 211564562Sgshapiro Support different directories for qf, df, and xf queue files; if 211664562Sgshapiro subdirectories or symbolic links to directories of those names 211764562Sgshapiro exist in the queue directories, they are used for the 211864562Sgshapiro corresponding queue files. Keep in mind, the queue 211964562Sgshapiro directory structure should not be changed while sendmail is 212064562Sgshapiro running. Proposed by Mathias Koerber of Singapore 212164562Sgshapiro Telecommunications Ltd. 212264562Sgshapiro New queue file naming system which uses a filename guaranteed to be 212364562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 212464562Sgshapiro without fancy file system locking. Queued items can be 212564562Sgshapiro moved between queues easily.

This can be used with LMTP 215064562Sgshapiro local delivery agents which listen on a named socket. An 215164562Sgshapiro example mailer might be: 215264562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 215364562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 215464562Sgshapiro A=FILE /var/run/lmtpd 215564562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 215664562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 215764562Sgshapiro instead. 215864562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 215964562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 216064562Sgshapiro connections), IPC (which will be deprecated in a future 216164562Sgshapiro version), and FILE (for UNIX domain socket delivery). 216264562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 216364562Sgshapiro flags. 216464562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 216564562Sgshapiro body of the original message on delivery status 216664562Sgshapiro notifications. 216764562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 216864562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 216964562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 217064562Sgshapiro Wrappers or the check_relay ruleset.

Proposed by 220264562Sgshapiro Mathias Herberts. 220364562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 220464562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 220564562Sgshapiro before the message has been collected, thereafter it holds 220664562Sgshapiro the message size as computed by sendmail (and can be used 220764562Sgshapiro in check_compat). 220864562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 220964562Sgshapiro sendmail is using instead of the value of the DeliveryMode 221064562Sgshapiro option. 221164562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 221264562Sgshapiro Drop explicit From: if same as what would be generated only if it is 221364562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 221464562Sgshapiro Write pid to file also if sendmail only processes the queue. 221564562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 221664562Sgshapiro Log "low on disk space" only when necessary. 221764562Sgshapiro New macro ${load_avg} can be used to check the current load average. 221864562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 221964562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 222064562Sgshapiro is set. 222164562Sgshapiro Flag -S for maps to specify the character which is substituted 222264562Sgshapiro for spaces (instead of the default given by O BlankSub). 222364562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 222464562Sgshapiro This flag is set by default for the host map. Based on a 222564562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 222664562Sgshapiro Open maps only on demand, not at startup. 222764562Sgshapiro Log warning about unsupported IP address families. 222864562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 222964562Sgshapiro of the sum of all headers. This can be used to prevent 223064562Sgshapiro a denial-of-service attack. 223164562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 223264562Sgshapiro headers and parameters within those headers. This option 223364562Sgshapiro is intended to protect mail user agents from buffer 223464562Sgshapiro overflow attacks. 223564562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 223664562Sgshapiro alias recursion. 223764562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 223864562Sgshapiro Map type syslog to log the key via syslogd. 223964562Sgshapiro Entries in the alias file can be continued by putting a backslash 224064562Sgshapiro directly before the newline. 224164562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 224264562Sgshapiro dead.letter file, formerly hardcoded to 224364562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 224464562Sgshapiro default), sendmail will not attempt to save to a 224564562Sgshapiro system-wide dead.letter file if it can not bounce the mail 224664562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 224764562Sgshapiro file as it has in the past when the dead.letter file 224864562Sgshapiro could not be opened. 224964562Sgshapiro New option PidFile to define the location of the pid file. The 225064562Sgshapiro value of this option is macro expanded. 225164562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 225264562Sgshapiro process title shown in 'ps' listings. 225364562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 225464562Sgshapiro (along with the already existing macros): 225564562Sgshapiro ${daemon_info} Daemon information, e.g. 225664562Sgshapiro SMTP+queueing@00:30:00 225764562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 225864562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 225964562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 226064562Sgshapiro ${daemon_port} Daemon port, e.g., 25 226164562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 226264562Sgshapiro New macros especially for virtual hosting: 226364562Sgshapiro ${if_name} hostname of interface of incoming connection. 226464562Sgshapiro ${if_addr} address of interface of incoming connection. 226564562Sgshapiro The latter is only set if the interface does not belong to the 226664562Sgshapiro loopback net. 226764562Sgshapiro If a message being accepted via a method other than SMTP and 226864562Sgshapiro would be rejected by a header check, do not send the message. 226964562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 227064562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 227164562Sgshapiro Provide header value as quoted string in the macro 227264562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 227364562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 227464562Sgshapiro The length of the header value is stored in ${hdrlen}. 227564562Sgshapiro H*: allows to specify a default ruleset for header checks. This 227664562Sgshapiro ruleset will only be called if the individual header does 227764562Sgshapiro not have its own ruleset assigned. Suggested by Jan 227864562Sgshapiro Krueger of Unix-AG of University of Hannover. 227964562Sgshapiro The name of the header field stored in ${hdr_name}. 228064562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 228164562Sgshapiro removed if the config file version is greater than or equal 228264562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 228364562Sgshapiro input "token (1)" but does not match "token". 228464562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 228564562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 228664562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 228764562Sgshapiro Ericsson. 228864562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 228964562Sgshapiro messages with 8-bit text in headers. Problem noted by 229064562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 229164562Sgshapiro of Ericsson. 229264562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 229364562Sgshapiro modified database map file. Problem noted by Chris Adams 229464562Sgshapiro of Renaissance Internet Services. 229564562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 229664562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 229764562Sgshapiro queue up the message instead of bouncing it. 229864562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 229964562Sgshapiro standard does not provide any indication of what to do when 230064562Sgshapiro something other than 250 is received. Based on a patch 230164562Sgshapiro from Steve Schweinhart of America Online. 230264562Sgshapiro New option TrustedUser allows to specify a user who can own 230364562Sgshapiro important files instead of root. This requires HASFCHOWN. 230464562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 230564562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 230664562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 230764562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 230864562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 230964562Sgshapiro $? tests also whether the macro is non-null. 231064562Sgshapiro Print an error message if a mailer definition contains an invalid 231164562Sgshapiro equate name. 231264562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 231364562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 231464562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 231564562Sgshapiro mailer to return after sending all data to it. 231664562Sgshapiro Only free memory from the process list when adding a new process 231764562Sgshapiro into a previously filled slot. Previously, the memory was 231864562Sgshapiro freed at removal time. Since removal can happen in a 231964562Sgshapiro signal handler, this may leave the memory map in an 232064562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 232164562Sgshapiro David Cooley of Colby College. 232264562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 232364562Sgshapiro local users in the passwd file. The UserDB code has 232464562Sgshapiro already decided the message will be passed to another host 232564562Sgshapiro for processing. Fix from Tony Landells of Burdett 232664562Sgshapiro Buckeridge Young Limited. 232764562Sgshapiro Support LDAP authorization via either a file containing the 232864562Sgshapiro password or Kerberos V4 using the new map options 232964562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 233064562Sgshapiro distinguished_name is who to login as. The method can be 233164562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 233264562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 233364562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 233464562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 233564562Sgshapiro of Stanford University. 233664562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 233764562Sgshapiro deprecated and will be removed in a future version. 233864562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 233964562Sgshapiro and the map has the column delimiter set, it turns that 234064562Sgshapiro response into a delimiter separated string. The LDAP map 234164562Sgshapiro will traverse multiple entries as well. LDAP alias maps 234264562Sgshapiro automatically set the column delimiter to the comma. 234364562Sgshapiro Based on patch from Booker Bense of Stanford University and 234464562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 234564562Sgshapiro Support return of multiple values for a single LDAP lookup. The 234664562Sgshapiro values to be returned should be in a comma separated string. 234764562Sgshapiro For example, `-v "email,emailother"'. Patch from 234864562Sgshapiro Curtis W. Hillegas of Princeton University. 234964562Sgshapiro Allow the use of LDAP for alias maps. 235064562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 235164562Sgshapiro attributes found in the match will be returned. 235264562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 235364562Sgshapiro breaking up a single entry into multiple entries. This is 235464562Sgshapiro needed for LDAP alias file specifications to allow for 235564562Sgshapiro comma separated key and value strings. 235664562Sgshapiro Keep connections to LDAP server open instead of opening and closing 235764562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 235864562Sgshapiro connections such that multiple maps which use the same 235964562Sgshapiro host, port, bind DN, and authentication will only result in 236064562Sgshapiro a single connection to that host. 236164562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 236264562Sgshapiro Be more careful about checking for errors and freeing memory on 236364562Sgshapiro LDAP lookups. 236464562Sgshapiro Use asynchronous LDAP searches to save memory and network 236564562Sgshapiro resources. 236664562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 236764562Sgshapiro Increase portability to the Netscape LDAP libraries. 236864562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 236964562Sgshapiro replaced with the literal contents of the map lookup key -- 237064562Sgshapiro note that this means a lookup can be done using the LDAP 237164562Sgshapiro special characters. The new '%0' token can be used instead 237264562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 237364562Sgshapiro For example, if the LDAP map specification contains '-k 237464562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 237564562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 237664562Sgshapiro user attribute. Instead, if the LDAP map specification 237764562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 237864562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 237964562Sgshapiro with the name "*". 238064562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 238164562Sgshapiro more than one is returned, it is equivalent to no records 238264562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 238364562Sgshapiro alias dereference option; "-Z size" limits the number of 238464562Sgshapiro matches to return. 238564562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 238664562Sgshapiro LDAP maps. The value should only contain LDAP specific 238764562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 238864562Sgshapiro settings will be used for all LDAP maps unless they are 238964562Sgshapiro specified in the individual map specification ('K' 239064562Sgshapiro command). This option should be set before any LDAP maps 239164562Sgshapiro are defined. 239264562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 239364562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 239464562Sgshapiro Tech. 239564562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 239664562Sgshapiro particular, class entries get much smaller, which can be 239764562Sgshapiro important if you have large classes. 239864562Sgshapiro On network-related temporary failures, record the hostname which 239964562Sgshapiro gave error in the queued status message. Requested by 240064562Sgshapiro Ulrich Windl of the Universitat Regensburg. 240164562Sgshapiro Add new F=% mailer flag to allow for a store and forward 240264562Sgshapiro configuration. Mailers which have this flag will not attempt 240371345Sgshapiro delivery on initial receipt of a message or on queue runs 240464562Sgshapiro unless the queued message is selected using one of the 240564562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 240664562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 240764562Sgshapiro New option ControlSocketName which, when set, creates a daemon 240864562Sgshapiro control socket. This socket allows an external program to 240964562Sgshapiro control and query status from the running sendmail daemon 241064562Sgshapiro via a named socket, similar to the ctlinnd interface to the 241164562Sgshapiro INN news server. Access to this interface is controlled by 241264562Sgshapiro the UNIX file permissions on the named socket on most UNIX 241364562Sgshapiro systems (see sendmail/README for more information). An 241464562Sgshapiro example control program is provided as contrib/smcontrol.pl. 241564562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 241664562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 241764562Sgshapiro number of processors online on the system (if that can be 241864562Sgshapiro determined). For single processor machines, this change 241964562Sgshapiro has no effect. 242064562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 242164562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 242264562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 242364562Sgshapiro Motonori Nakamura of Kyoto University. 242464562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 242564562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 242664562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 242764562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 242864562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 242964562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 243064562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 243164562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 243264562Sgshapiro connection-based denial of service attacks. 243364562Sgshapiro Log basic information about authenticated connections at LogLevel 243464562Sgshapiro 10 or higher. 243564562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 243664562Sgshapiro information (from= syslog line). 243764562Sgshapiro Log the DSN code for each recipient if one is available as a new 243864562Sgshapiro equate (dsn=). 243964562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 244064562Sgshapiro New "ph" map for performing ph queries in rulesets.

Contributed by Mark 244371345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 244464562Sgshapiro Detect temporary lookup failures in the host map if looking up a 244564562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 244664562Sgshapiro Finnish Meteorological Institute. 244764562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 244864562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 244964562Sgshapiro When a forward file points to an alias which runs a program, run 245064562Sgshapiro the program as the default user and the default group, not 245164562Sgshapiro the forward file user. This change also assures the 245264562Sgshapiro :include: directives in aliases are also processed using 245364562Sgshapiro the default user and group. Problem noted by Sergiu 245464562Sgshapiro Popovici of DNT Romania. 245564562Sgshapiro Prevent attempts to save a dead.letter file for a user with 245664562Sgshapiro no home directory (/no/such/directory). Problem noted by 245764562Sgshapiro Michael Brown of Finnigan FT/MS. 245864562Sgshapiro Include message delay and number of tries when logging that a 245964562Sgshapiro message has been completely delivered (LogLevel of 10 or 246064562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 246164562Sgshapiro Log the sender of a message even if none of the recipients were 246264562Sgshapiro accepted. If some of the recipients were rejected, it is 246364562Sgshapiro helpful to know the sender of the message. 246464562Sgshapiro Check the root directory (/) when checking a path for safety. 246564562Sgshapiro Problem noted by John Beck of Sun Microsystems. 246664562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 246764562Sgshapiro interactive and delivering to an alias which resolves to 246864562Sgshapiro multiple files. 246964562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 247064562Sgshapiro greater (see below); the help function doesn't print the 247164562Sgshapiro version of sendmail any longer, instead it is placed in 247264562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 247364562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 247464562Sgshapiro skipped and a version line (#vers) is introduced. The 247564562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 247664562Sgshapiro version is found, a warning is logged. The '#vers' 247764562Sgshapiro directive should be placed at the top of the help file. 247864562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 247964562Sgshapiro disk succeeded. Suggested by Nick Christenson. 248064562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 248164562Sgshapiro length before the attempt. 248264562Sgshapiro If a forward points to a filename for delivery, change to the 248364562Sgshapiro user's uid before checking permissions on the file. This 248464562Sgshapiro allows delivery to files on NFS mounted directories where 248564562Sgshapiro root is remapped to nobody. Problem noted by Harald 248664562Sgshapiro Daeubler of Universitaet Ulm. 248764562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 248864562Sgshapiro host status files, not all files. 248964562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 249064562Sgshapiro in the queue file for the message and set when delivery 249164562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 249264562Sgshapiro Wonderworks Inc. 249364562Sgshapiro Add support for storing information between rulesets using the new 249464562Sgshapiro macro map class. This can be used to store information 249564562Sgshapiro between queue runs as well using $={persistentMacros}. 249664562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 249764562Sgshapiro of Hannover. 249864562Sgshapiro New map class arith to allow for computations in rules. The 249964562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 250064562Sgshapiro as key. The two operands are specified as arguments; the 250164562Sgshapiro lookup returns the result of the computation. For example, 250264562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 250364562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 250464562Sgshapiro Add new syntax for header declarations which decide whether to 250564562Sgshapiro include the header based on a macro rather than a mailer 250664562Sgshapiro flag: 250764562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 250864562Sgshapiro This should be used along with $={persistentMacros}. 250964562Sgshapiro It can be used for adding headers to a message based on 251064562Sgshapiro the results of check_* and header check rulesets. 251164562Sgshapiro Allow new named config file rule check_eoh which is called after 251264562Sgshapiro all of the headers have been collected. The input to the 251364562Sgshapiro ruleset the number of headers and the size of all of the 251464562Sgshapiro headers in bytes separated by $|. This ruleset along with 251564562Sgshapiro the macro storage map can be used to correlate information 251664562Sgshapiro gathered between headers and to check for missing headers. 251764562Sgshapiro See cf/README or doc/op/op.ps for an example. 251864562Sgshapiro Change the default for the MeToo option to True to correspond 251964562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 252064562Sgshapiro option is deprecated and will be removed from a future 252164562Sgshapiro version. 252264562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 252364562Sgshapiro Change the sendmail binary default for SuperSafe to True. 252464562Sgshapiro Display ruleset names in debug and address test mode output 252564562Sgshapiro if referencing a named ruleset. 252664562Sgshapiro New mailer equate m= which will limit the number of messages 252764562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 252864562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 252964562Sgshapiro using it to sort. Now all the same domains are really run 253064562Sgshapiro through the queue together. If they have the same MX host, 253164562Sgshapiro then they will have a much better opportunity to use the 253264562Sgshapiro connection cache if available. This should be a reasonable 253364562Sgshapiro performance improvement. Patch from Randall Winchester of 253464562Sgshapiro the University of Maryland. 253564562Sgshapiro If a message is rejected by a header check ruleset, log who would 253664562Sgshapiro have received the message if it had not been rejected. 253764562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 253864562Sgshapiro queue immediately. No delivery attempt is made. 253964562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 254064562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 254164562Sgshapiro COMMANDS). 254264562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 254364562Sgshapiro but for outgoing connections. 254464562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 254564562Sgshapiro error messages and logging) and Modifiers, i.e. 254664562Sgshapiro a require authentication 254764562Sgshapiro b bind to interface through which mail has 254864562Sgshapiro been received 254964562Sgshapiro c perform hostname canonification 255064562Sgshapiro f require fully qualified hostname 255164562Sgshapiro h use name of interface for outgoing HELO 255264562Sgshapiro command 255364562Sgshapiro C don't perform hostname canonification 255464562Sgshapiro E disallow ETRN (see RFC 2476) 255564562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 255664562Sgshapiro h use name of interface for HELO command 255764562Sgshapiro The version number for queue files (qf) has been incremented to 4. 255864562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 255964562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 256064562Sgshapiro Institutes of Health. 256164562Sgshapiro If a mailer dies, print the status in decimal instead of octal 256264562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 256364562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 256464562Sgshapiro Move message priority from sender to recipient logging. Suggested by 256564562Sgshapiro Ulrich Windl of the Universitat Regensburg. 256664562Sgshapiro Add support for Berkeley DB 3.X. 256764562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 256864562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 256964562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 257064562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 257164562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 257264562Sgshapiro sub-options is set on the command line. Problem noted by 257364562Sgshapiro Graeme Hewson of Oracle. 257464562Sgshapiro Randomize equal preference MX records each time delivery is 257564562Sgshapiro attempted via a new connection to a host instead of once per 257664562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 257764562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 257864562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 257964562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 258064562Sgshapiro to hosts which have dynamically assigned names. 258164562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 258264562Sgshapiro the bounce for the same reason. If the body is not 8-bit 258364562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 258464562Sgshapiro not be included in the bounce. Problem noted by Valdis 258564562Sgshapiro Kletnieks of Virginia Tech. 258664562Sgshapiro The timeout for sending a message via SMTP has been changed from 258764562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 258864562Sgshapiro simply checks for progress on sending data every 5 minutes. 258964562Sgshapiro This will detect the inability to send information quicker 259064562Sgshapiro and reduce the number of processes simply waiting to 259164562Sgshapiro timeout. 259264562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 259364562Sgshapiro interface address structure when loading the system network 259464562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 259564562Sgshapiro Nanoteq. 259664562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 259764562Sgshapiro indicates the number of interfaces to read when probing 259864562Sgshapiro for hostnames and IP addresses for class w ($=w). The 259964562Sgshapiro default value is 512. Based on idea from Reinier 260064562Sgshapiro Bezuidenhout of Nanoteq. 260164562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 260264562Sgshapiro on load average. 260364562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 260464562Sgshapiro Northern Illinois University. 260564562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 260664562Sgshapiro envelope splitting has occurred. 260764562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 260864562Sgshapiro Luke Mewburn from RMIT University. 260964562Sgshapiro Add a "/quit" command to address test mode. 261064562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 261164562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 261264562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 261364562Sgshapiro Institute. 261464562Sgshapiro The contents of a class can now be copied to another class using 261564562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 261664562Sgshapiro the items in class $={Source} into the class $={Dest}. 261764562Sgshapiro Include original envelope's error transcript in bounces created for 261864562Sgshapiro split (owner-) envelopes to see the original errors when 261964562Sgshapiro the recipients were added. Based on fix from Motonori 262064562Sgshapiro Nakamura of Kyoto University. 262164562Sgshapiro Show reason for permanent delivery errors directly after the 262264562Sgshapiro addresses.

Problem noted by Per 271364562Sgshapiro Hedeland of Ericsson. 271464562Sgshapiro mailq displays unprintable characters in addresses as their octal 271564562Sgshapiro representation and a leading backslash. This avoids problems 271664562Sgshapiro with "unprintable" characters. Problem noted by Michal 271764562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 271864562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 271964562Sgshapiro one character past the limit. This would cause subsequent 272064562Sgshapiro hops to break the line again. The '!' is now placed in 272164562Sgshapiro the last column of the limit if the line needs to be broken. 272264562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 272364562Sgshapiro from Per Hedeland of Ericsson. 272464562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 272564562Sgshapiro resolver will fall back to TCP. However, some 272664562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 272764562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 272864562Sgshapiro don't fail on ANY queries. 272964562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 273064562Sgshapiro address, do not send an empty postmaster notification DSN 273164562Sgshapiro to the postmaster.

Problem noted by Ezequiel H. Panepucci of 303364562Sgshapiro Yale University. 303464562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 303564562Sgshapiro be used for building. 303664562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 303764562Sgshapiro used for a fresh build. 303864562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 303964562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 304064562Sgshapiro ranlib. 304164562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 304264562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 304364562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 304464562Sgshapiro building of the man pages when defined. Suggested by Bryan 304564562Sgshapiro Costales. 304664562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 304764562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 304864562Sgshapiro installation of the sendmail helpfile and statistics file 304964562Sgshapiro respectively. Suggested by Bryan Costales. 305064562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 305164562Sgshapiro of Siemens Business Services. 305264562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 305364562Sgshapiro stdio library. The new buffered file I/O depends on the 305464562Sgshapiro Torek stdio library. This option can be either portable or 305564562Sgshapiro torek. 305664562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 305764562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 305864562Sgshapiro They should contain the C source files for the object files 305964562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 306064562Sgshapiro will be passed to the 'make depend' stage of compilation. 306164562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 306264562Sgshapiro in the sendmail distribution. Each has the form 306364562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 306464562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 306564562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 306664562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 306764562Sgshapiro building the distribution, but documentation on the changes 306864562Sgshapiro are in devtools/README. 306964562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 307064562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 307164562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 307264562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 307364562Sgshapiro new variable which identifies the root of the source 307464562Sgshapiro directories for all of the programs in the distribution. 307564562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 307664562Sgshapiro time. They can both still be overridden by setting the m4 307764562Sgshapiro macro. 307864562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 307964562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 308064562Sgshapiro build configurations, and places objects in obj.prefix.*/. 308164562Sgshapiro Complains as 'Build -f file' does for existing object 308264562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 308364562Sgshapiro Corporation. 308464562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 308564562Sgshapiro manual pages in the directory tree specified by 308664562Sgshapiro confMANROOTMAN. 308764562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 308864562Sgshapiro preformatted pages from the distribution. The new variable 308964562Sgshapiro confCOPY specifies the copying program. 309064562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 309164562Sgshapiro question. Suggested by Terry Lambert of Whistle 309264562Sgshapiro Communications. 309364562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 309464562Sgshapiro of the installed statistics and help files, respectively. 309564562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 309664562Sgshapiro operating system identity. Problem noted by Erik 309764562Sgshapiro Wachtenheim of Dartmouth College. 309864562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 309964562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 310064562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 310164562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 310264562Sgshapiro how to strip binaries. These are used by the new 310364562Sgshapiro install-strip target. 310464562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 310564562Sgshapiro the others (if it exists). 310664562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 310764562Sgshapiro then the default ones. 310890792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 310964562Sgshapiro as local delivery agent without LMTP mode, use 311064562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 311164562Sgshapiro to set the S flag. 311264562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 311364562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 311464562Sgshapiro Northern Illinois University. 311564562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 311664562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 311764562Sgshapiro the Finnish Meteorological Institute. 311864562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 311964562Sgshapiro MAILLOCK when compiling. Also requires linking with 312064562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 312164562Sgshapiro University. 312264562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 312364562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 312464562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 312564562Sgshapiro University. 312664562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 312764562Sgshapiro structure to the beginning of the program. This ensures that 312864562Sgshapiro the getservbyname() is done before any seteuid to a possibly 312964562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 313064562Sgshapiro on a Solaris system, this avoids syslog messages such as, 313164562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 313264562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 313364562Sgshapiro University. 313464562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 313564562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 313664562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 313764562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 313864562Sgshapiro characters (in LMTP mode), mail.local split the incoming 313964562Sgshapiro line up into 2046-character output lines (excluding the 314064562Sgshapiro newline). If an input line was 2047 characters long 314164562Sgshapiro (excluding CR-LF) and the last character was a '.', 314264562Sgshapiro mail.local saw it as the end of input, transfered it to the 314364562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 314464562Sgshapiro If the message was much longer, both sendmail and 314564562Sgshapiro mail.local would deadlock waiting for each other to read 314664562Sgshapiro what they have written. Problem noted by Peter Jeremy of 314764562Sgshapiro Alcatel Australia Limited. 314864562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 314964562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 315064562Sgshapiro Neil Rickert of Northern Illinois University. 315164562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 315264562Sgshapiro timeout to avoid starvation. 315364562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 315464562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 315564562Sgshapiro Infinite Monkeys & Co. 315664562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J.

Sites 363838032Speter which need the ability to override security can use the 363938032Speter DontBlameSendmail option. See the README file for more 364038032Speter information. 364138032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 364238032Speter if maps or alias files are in world writable directories. 364338032Speter This fixes the change added to 8.8.6 to prevent links in these 364438032Speter world writable directories. 364538032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 364638032Speter it is in a world writable directory. 364738032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 364838032Speter tty it may be able to push bytes back to the senders input. 364938032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 365838032Speter reverts back to the old behavior of using uid 1 and gid 1. 365938032Speter This is a security problem for Linux which has chosen that 366038032Speter uid and gid for user bin instead of daemon. If DefaultUser 366138032Speter is set in the configuration file, that value overrides this 366238032Speter default. 366390792Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-ID binaries 366438032Speter interfered with setting an alternate group id for the 366538032Speter RunAsUser option.

After this number is reached, sendmail 370938032Speter starts returning "452 Too many recipients" to all RCPT 371038032Speter commands. This can be used to limit the number of recipients 371138032Speter per envelope (in particular, to discourage use of the server 371238032Speter for spamming). Note: a better approach is to restrict 371338032Speter relaying entirely. 371438032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 371538032Speter to ldapx map and added timeout for ldap_open call to 371638032Speter avoid hanging sendmail in the event of hung LDAP servers. 371738032Speter Patch from Booker Bense of Stanford University. 371838032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 374138032Speter of Procter & Gamble. 374238032Speter New DontBlameSendmail option. This option allows administrators to 374338032Speter bypass some of sendmail's file security checks at the expense 374438032Speter of system security. This should only be used if you are 374538032Speter absolutely sure you know the consequences.

In particular, if you 378038032Speter have lots of virtual interfaces, this option will speed up 378138032Speter startup. However, unless you make other arrangements, mail 378238032Speter sent to those addresses will be bounced. 378338032Speter Automatically create alias databases if they don't exist and 378438032Speter AutoRebuildAliases is set. 378538032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 378638032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 378738032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 378838032Speter When determining the client host name ($&{client_name} macro), do 378938032Speter a forward (A) DNS lookup on the result of the PTR lookup 379038032Speter and compare results. If they differ or if the PTR lookup 379138032Speter fails, &{client_name} will contain the IP address 379264562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 379338032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 379438032Speter (i.e, it is like -ax for the temporary failure case, in 379538032Speter contrast to the success case). 379638032Speter New syntax to do limited checking of header syntax. A config line 379738032Speter of the form: 379838032Speter HHeader: $>Ruleset 379938032Speter causes the indicated Ruleset to be invoked on the Header 380038032Speter when read. This ruleset works like the check_* rulesets -- 380138032Speter that is, it can reject mail on the basis of the contents. 380238032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 380338032Speter from hiding their connection information in Received: 380438032Speter headers. 380538032Speter When SingleThreadDelivery is active, deliveries to locked hosts 380638032Speter are skipped. This will cause the delivering process to 380738032Speter try the next MX host or queue the message if no other MX 380838032Speter hosts are available. Suggested by Alexander Litvin. 380938032Speter The [FILE] mailer type now delivers to the file specified in the 381038032Speter A= equate of the mailer definition instead of $u. It also 381138032Speter obeys all of the F= mailer flags such as the MIME 381238032Speter 7/8 bit conversion flags. This is useful for defining 381338032Speter a mailer which delivers to the same file regardless of the 381464562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 381538032Speter Do not assume the identity of a remote connection is root@localhost 381638032Speter if the remote connection closes the socket before the 381738032Speter remote identity can be queried. 381838032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 381938032Speter Some mailers, including procmail, require that the real 382038032Speter uid is left unchanged by sendmail. Problem noted by Per 382138032Speter Hedeland of Ericsson. 382238032Speter No longer is the src/obj*/Makefile selected from a large list -- it 382338032Speter is now generated using the information in BuildTools/OS/ -- 382438032Speter some of the details are determined dynamically via 382538032Speter BuildTools/bin/configure.sh. 382638032Speter The other programs in the sendmail distribution -- mail.local, 382738032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 382838032Speter the new Build method which creates an operating system 382938032Speter specific Makefile using the information in BuildTools. 383038032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 383138032Speter a failure on one message won't affect future messages to the 383238032Speter same host). This is necessary if the remote host sends 383338032Speter a 451 error if the domain of the sender does not resolve 383438032Speter as is common in anti-spam configurations. Problem noted 383538032Speter by Mitchell Blank Jr of Exec-PC. 383638032Speter New "discard" mailer for check_* rulesets and header checking 383738032Speter rulesets. If one of the above rulesets resolves to the 383838032Speter $#discard mailer, the commands will be accepted but the 383938032Speter message will be completely discarded after it is accepting. 384038032Speter This means that even if only one of the recipients 384138032Speter resolves to the $#discard mailer, none of the recipients 384238032Speter will receive the mail. Suggested by Brian Kantor. 384338032Speter All but the last cloned envelope of a split envelope were queued 384438032Speter instead of being delivered.

Suggested by Scott 386138032Speter Gifford of The Internet Ramp. 386238032Speter Sendmail would get a segmentation fault if a mailer exited with an 386338032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 386438032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 386538032Speter Institute. 386638032Speter Separate snprintf/vsnprintf routines into separate file for use by 386738032Speter mail.local. 386838032Speter Allow multiple map lookups on right hand side, e.g., 386938032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 387038032Speter Christophe Wolfhugel of the Pasteur Institute. 387138032Speter Properly generate success DSN messages if requested for aliases 387238032Speter which have owner- aliases.

Note that this changes the default from 395838032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 395938032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 396038032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 396138032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 396238032Speter the user to setup different .forward files for 396338032Speter user+detail addressing. 396438032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 396538032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 396638032Speter DontProbeInterfaces, and DontBlameSendmail options. 396738032Speter CONFIG: by default do not allow relaying (that is, accepting mail 396838032Speter from outside your domain and sending it to another host 396938032Speter outside your domain). 397038032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 397138032Speter any site to any site. 397238032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 397338032Speter domain as defined by the 'm' class ($=m) to relay. 397438032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 397538032Speter the MX records of the host portion of an incoming recipient. 397638032Speter CONFIG: new FEATURE(access_db) which turns on the access database 397777349Sgshapiro feature. This database gives you the ability to allow 397838032Speter or refuse to accept mail from specified domains for 397938032Speter administrative reasons. By default, names that are listed 398038032Speter as "OK" in the access db are domain names, not host names. 398138032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 398238032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 398338032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 398438032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 398538032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 398638032Speter of FEATURE(access_db) and class 'R' to lookup individual 398738032Speter host names only. 398838032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 398938032Speter using % addressing is used, e.g. user%site@othersite, 399038032Speter and othersite is in class 'R', the check_rcpt ruleset 399138032Speter will strip @othersite and recheck user@site for relaying. 399238032Speter This feature changes that behavior. It should not be 399338032Speter needed for most installations. 399438032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 399538032Speter domain portion of the mail sender is a local host. This 399638032Speter should only be used if absolutely necessary as it opens 399738032Speter a window for spammers. Patch from Randall S. Winchester of 399838032Speter the University of Maryland. 399938032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 400038032Speter block incoming mail destined for certain recipient 400138032Speter usernames, hostnames, or addresses. 400238032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 400338032Speter refused if the host part of the argument to MAIL FROM: cannot 400438032Speter be located in the host name service (e.g., DNS). 400538032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 400638032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 400738032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 400838032Speter MAIL FROM: senders which do not include a domain. 400938032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 401038032Speter Realtime Blackhole List. You can specify the RBL name 401138032Speter server to contact by specifying it as an optional argument. 401238032Speter The default is rbl.maps.vix.com.

Problem noted by Kari Hurtta of the Finnish 415838032Speter Meteorological Institute. 415938032Speter If /usr/tmp/dead.letter already existed, sendmail could not 416038032Speter add additional bounces to it. Problem noted by Thomas J. 416138032Speter Arseneault of SRI International. 416238032Speter If an SMTP mailer used a non-standard port number for the outgoing 416338032Speter connection, it would be displayed incorrectly in verbose mode. 416438032Speter Problem noted by John Kennedy of Cal State University, Chico. 416538032Speter Log the ETRN parameter specified by the client before altering them 416638032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 416738032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 416838032Speter User unknown with bogus delay= values. Change them to log 416938032Speter the same as compliant addresses. Problem noted by Kari E. 417038032Speter Hurtta of the Finnish Meteorological Institute. 417138032Speter Ignore the debug resolver option unless using sendmail debug trace 417238032Speter option for resolver. Problem noted by Greg Nichols of Wind 417338032Speter River Systems. 417438032Speter If SingleThreadDelivery was enabled and the remote server returned a 417538032Speter protocol error on the DATA command, the connection would be 417638032Speter closed but the persistent host status file would not be 417738032Speter unlocked so other sendmail processes could not deliver to 417838032Speter that host. Problem noted by Peter Wemm of DIALix. 417938032Speter If queueing up a message due to an expensive mailer, don't increment 418038032Speter the number of delivery attempts or set the last delivery 418138032Speter attempt time so the message will be delivered on the next 418238032Speter queue run regardless of MinQueueAge. Problem noted by 418338032Speter Brian J. Coan of the Institute for Global Communications. 418438032Speter Authentication warnings of "Processed from queue _directory_" and 418538032Speter "Processed by _username_ with -C _filename_" would be logged 418638032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 418738032Speter of the Finnish Meteorological Institute. 418838032Speter Use a better heuristic for detecting GDBM. 418938032Speter Log null connections on dropped connections. Problem noted by 419038032Speter Jon Lewis of Florida Digital Turnpike. 419138032Speter If class dbm maps are rebuilt, sendmail will now detect this and 419238032Speter reopen the map. Previously, they could give stale 419338032Speter results during a single message processing (but would 419438032Speter recover when the next message was received). Fix from 419538032Speter Joe Pruett of Q7 Enterprises. 419638032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 419738032Speter requests. Problem noted by Kari E. Hurtta of the 419838032Speter Finnish Meteorological Institute. 419938032Speter Do not send a bounce message back to the sender regarding bad 420038032Speter recipients if the SMTP connection is dropped before the 420138032Speter message is accepted. Problem noted by Kari E. Hurtta of the 420238032Speter Finnish Meteorological Institute. 420338032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 420438032Speter sendmail via a UNIX pipe. This will allow rulesets using 420538032Speter $&{client_name} to process without sending the string through 420638032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 420738032Speter A combination of deferred delivery mode, a double bounce situation, 420838032Speter and the inability to save a bounce message to 420938032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 421038032Speter to postmaster but not remove the offending envelope from the 421138032Speter queue causing it to create a new bounce message each time the 421238032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 421338032Speter Associates. 421438032Speter Remove newlines from hostname information returned via DNS. There are 421538032Speter no known security implications of newlines in hostnames as 421638032Speter sendmail filters newlines in all vital areas; however, this 421738032Speter could cause confusing error messages. 421838032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 421938032Speter rejected if any of the specified addresses were bad. This 422038032Speter behavior was modified to only reject the bad addresses and not 422138032Speter the entire message. Problem noted by Jozsef Hollosi of 422238032Speter SuperNet, Inc. 422338032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 422438032Speter Bryan Costales of InfoBeat, Inc. 422538032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 422638032Speter mailers. Problem noted by Kari E. Hurtta of the 422738032Speter Finnish Meteorological Institute. 422838032Speter An error in calculating the available space in the list of addresses 422938032Speter for logging deliveries could cause an address to be silently 423038032Speter dropped. 423138032Speter Include the initial user environment if sendmail is restarted via 423238032Speter a HUP signal. This will give room for the process title. 423338032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 423438032Speter Mail could be delivered without a body if the machine does not 423538032Speter support flock locking and runs out of processes during 423638032Speter delivery. Fix from Chuck Lever of the University of Michigan. 423738032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 423838032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 423938032Speter Institute. 424038032Speter Make sure non-rebuildable database maps are opened before the 424164562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 424238032Speter are needed for verifying the left hand side of the aliases. 424338032Speter Problem noted by Lloyd Parkes of Victoria University. 424438032Speter Make sure sender RFC822 source route addresses are alias expanded for 424538032Speter bounce messages. Problem noted by Juergen Georgi of 424638032Speter RUS University of Stuttgart. 424738032Speter Minor lint fixes. 424838032Speter Return a temporary error instead of a permanent error if an LDAP map 424938032Speter search returns an error. This will allow sequenced maps which 425038032Speter use other LDAP servers to be checked. Fix from Booker Bense 425138032Speter of Stanford University. 425238032Speter When automatically converting from quoted printable to 8bit text do 425338032Speter not pad bare linefeeds with a space. Problem noted by Theo 425438032Speter Nolte of the University of Technology Aachen, Germany. 425538032Speter Portability: 425638032Speter Non-standard C compilers may have had a problem compiling 425738032Speter conf.c due to a standard C external declaration of 425838032Speter setproctitle(). Problem noted by Ted Roberts of 425938032Speter Electronic Data Systems. 426038032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 426138032Speter Jagielski of jaguNET Access Services. 426238032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 426338032Speter Digital UNIX: Digital UNIX (and possibly others) moves 426438032Speter loader environment variables into the loader memory 426538032Speter area. If one of these environment variables (such as 426638032Speter LD_LIBRARY_PATH) was the last environment variable, 426738032Speter an invalid memory address would be used by the process 426838032Speter title routine causing memory corruption. Problem 426938032Speter noted by Sam Hartman of Mesa Internet Systems. 427038032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 427138032Speter chownsafe() to always return 0 even if the OS does 427238032Speter not permit file giveaways. Problem noted by 427338032Speter Yasutaka Sumi of The University of Tokyo. 427464562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 427538032Speter Gerald Rinske of Siemens Business Services VAS. 427638032Speter Linux: Pad process title with NULLs. Problem noted by 427738032Speter Jon Lewis of Florida Digital Turnpike. 427838032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 427938032Speter incorrect value for the number of interfaces. 428038032Speter Problem noted by Chris Loelke of JetStream Internet 428138032Speter Services. 428238032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 428338032Speter Rinske of Siemens Business Services VAS. 428438032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 428538032Speter used on a Solaris machine. Problem noted by 428638032Speter Stephen Ma of Jtec Pty Limited. 428738032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 428838032Speter Services VAS. 428938032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 429038032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 429138032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 429238032Speter Ericsson. 429338032Speter 429464562Sgshapiro8.8.7/8.8.7 1997/08/03 429538032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 429638032Speter an exclusive lock already set -- i.e., almost all systems 429738032Speter except 4.4-BSD derived systems), the initial attempt at 429838032Speter rebuilding aliases file if the database didn't already 429938032Speter exist would fail. Patch from Raymund Will of LST Software 430038032Speter GmbH. 430138032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 430238032Speter Problem noted by Fredrik J�nsson of the Royal Institute 430338032Speter of Technology, Stockholm. 430438032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 430538032Speter some environments could give "multiple definitions" for these 430638032Speter routines during compilation. If using TCP Wrappers, assume 430738032Speter that these routines are included as though they were in the 430838032Speter C library. Patch from Robert La Ferla. 430938032Speter When a NEWDB database map was rebuilt at the same time it was being 431038032Speter used by a queue run, the maps could be left locked for the 431138032Speter duration of the queue run, causing other processes to hang. 431238032Speter Problem noted by Kendall Libby of Shore.NET. 431338032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 431438032Speter mail was passed on without any recipient header. This could 431538032Speter cause problems downstream. Problem noted by Xander Jansen 431638032Speter of SURFnet ExpertiseCentrum. 431738032Speter Give error when GDBM is used with sendmail. GDBM's locking and 431838032Speter linking of the .dir and .pag files interferes with sendmail's 431938032Speter locking and security checks. Problems noted by Fyodor 432038032Speter Yarochkin of the Kyrgyz Republic FreeNet. 432138032Speter Don't fsync qf files if SuperSafe option is not set. 432238032Speter Avoid extra calls to gethostbyname for addresses for which a 432338032Speter gethostbyaddr found no value. Also, ignore any returns 432438032Speter from gethostbyaddr that look like a dotted quad. 432538032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 432638032Speter "may be forged", since at the network level we pretty much 432738032Speter have to assume that the information is good. 432838032Speter In some cases, errors during an SMTP session could leave files 432938032Speter open or locked. 433038032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 433190792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 433238032Speter errors during testing. 433338032Speter Errors in file locking of NEWDB maps had the incorrect file name 433438032Speter printed in the error message. 433538032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 433638032Speter missing parameter were issued, the EHLO behaved like a HELO. 433738032Speter Load limiting never kicked in for incoming SMTP transactions if the 433843730Speter DeliveryMode=background and any recipient was an alias or 433938032Speter had a .forward file. From Nik Conwell of Boston University. 434038032Speter On some non-Posix systems, the decision of whether chown(2) permits 434138032Speter file giveaway was undefined. From Tetsu Ushijima of the 434238032Speter Tokyo Institute of Technology. 434338032Speter Fix race condition that could cause the body of a message to be 434438032Speter lost (so only the header was delivered). This only occurs 434538032Speter on systems that do not use flock(2), and only when a queue 434638032Speter runner runs during a critical section in another message 434738032Speter delivery. Based on a patch from Steve Schweinhart of 434838032Speter Results Computing. 434938032Speter If a qf file was found in a mail queue directory that had a problem 435038032Speter (wrong ownership, bad format, etc.) and the file name was 435138032Speter exactly MAXQFNAME bytes long, then instead of being tried 435238032Speter once, it would be tried on every queue run. Problem noted 435338032Speter by Bryan Costales of Mercury Mail. 435438032Speter If the system supports an st_gen field in the status structure, 435538032Speter include it when reporting that a file has changed after open. 435638032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 435738032Speter This out to be checked as well as reported, since it is 435838032Speter theoretically possible for an attacker to remove a file after 435938032Speter it is opened and replace it with another file that has the 436038032Speter same i-number, but some filesystems (notably AFS) return 436138032Speter garbage in this field, and hence always look like the file 436238032Speter has changed. As a practical matter this is not a security 436338032Speter problem, since the files can be neither hard nor soft links, 436438032Speter and on no filesystem (that I am aware of) is it possible to 436538032Speter have two files on the same filesystem with the same i-number 436638032Speter simultaneously. 436738032Speter Delete the root Makefile from the distribution -- it is only for 436838032Speter use internally, and does not work at customer sites. 436938032Speter Fix botch that caused the second MAIL FROM: command in a single 437038032Speter transaction to clear the entire transaction. Problem 437138032Speter noted by John Kennedy of Cal State University, Chico. 437238032Speter Work properly on machines that have _PATH_VARTMP defined without 437338032Speter a trailing slash. (And a pox on vendors that decide to 437438032Speter ignore the established conventions!) Problem noted by 437538032Speter Gregory Neil Shapiro of WPI. 437638032Speter Internal changes to make it easier to add another protocol family 437738032Speter (intended for IPv6). Patches are from John Kennedy of 437838032Speter CSU Chico. 437938032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 438038032Speter an extra space at the beginning of some lines. Problem 438138032Speter noted by Charles Karney of Princeton University; fix based 438238032Speter on a patch from Christophe Wolfhugel. 438338032Speter Portability: 438438032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 438538032Speter with the _Sendmail_ book, 2nd edition. Note that 438638032Speter the book is actually wrong: _PATH_SENDMAILCF should 438738032Speter be used instead. 438838032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 438938032Speter of Argonne National Laboratory. 439038032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 439138032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 439238032Speter SunOS: Include <memory.h> to fix warning from util.c. From 439338032Speter James Aldridge of EUnet Ltd. 439438032Speter Solaris: Change STDIR (location of status file) to /etc/mail 439538032Speter in Makefiles. 439638032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 439738032Speter Makefiles. Use NEWDB on Linux instead. 439838032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 439938032Speter exists but behaves differently than other OSes. 440038032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 440138032Speter around the problem. Problem noted by Tom Moore of 440238032Speter NCR Corp. 440338032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 440438032Speter noted by Tom Smith of Digital Equipment Corp. 440538032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 440638032Speter noted by Tom Good of the Community Access Information 440738032Speter Resource Network 440838032Speter SCO 4.2: compile problems caused by a change in the type of 440938032Speter the "length" parameters passed to accept, getpeername, 441038032Speter getsockname, and getsockopt. Adds new compile flags 441138032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.

This makes it possible to create a root 445638032Speter owned file in an arbitrary directory by inserting the symlink 445738032Speter into a writable directory after the initial lstat(2) check 445838032Speter determined that the file did not exist. The only verified 445938032Speter example of a system having these odd semantics for O_EXCL 446038032Speter and symbolic links was HP-UX prior to version 9.07. Most 446138032Speter systems do not have the problem, since a exclusive create 446238032Speter of a file disallows symbolic links. Systems that have been 446338032Speter verified to NOT have the problem include AIX 3.x, *BSD, 446438032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 446538032Speter and Ultrix. This is a potential exposure on systems that 446638032Speter have this bug and which do not have a MAILER-DAEMON alias 446738032Speter pointing at a legitimate account, since this will cause old 446838032Speter mail to be dropped in /var/tmp/dead.letter. 446938032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 447038032Speter if maps or alias files are in world writable directories. 447138032Speter If your system has alias maps in writable directories, it 447238032Speter is potentially possible for an attacker to replace the .db 447338032Speter (or .dir and .pag) files by symbolic links pointing at 447438032Speter another database; this can be used either to expose 447538032Speter information (e.g., by pointing an alias file at /etc/spwd.db 447638032Speter and probing for accounts), or as a denial-of-service attack 447738032Speter (by trashing the password database). The fix disallows 447838032Speter symbolic links entirely when rebuilding alias files or on 447938032Speter maps that are in writable directories, and always warns on 448038032Speter writable directories; 8.9 will probably consider writable 448138032Speter directories to be fatal errors. This does not represent an 448238032Speter exposure on systems that have alias files in unwritable 448338032Speter system directories. 448438032Speter SECURITY: disallow .forward or :include: files that are links (hard 448538032Speter or soft) if the parent directory (or any directory in the 448638032Speter path) is writable by anyone other than the owner. This is 448738032Speter similar to the previous case for user files. This change 448838032Speter should not affect most systems, but is necessary to prevent 448938032Speter an attacker who can write the directory from pointing such 449038032Speter files at other files that are readable only by the owner. 449138032Speter SECURITY: Tighten safechown rules: many systems will say that they 449238032Speter have a safe (restricted to root) chown even on files that 449338032Speter are mounted from another system that allows owners to give 449438032Speter away files. The new rules are very strict, trusting file 449538032Speter ownership only in those few cases where the system has 449638032Speter been verified to be at least as paranoid as necessary. 449738032Speter However, it is possible to relax the rules to partially 449838032Speter trust the ownership if the directory path is not world or 449938032Speter group writable. This might allow someone who has a legitimate 450038032Speter :include: file (referenced directly from /etc/aliases) to 450138032Speter become another non-root user if the :include: file is in a 450238032Speter non-writable directory on an NFS-mounted filesystem where 450338032Speter the local system says that giveaway is denied but it is 450438032Speter actually permitted. I believe this to be a very small set 450538032Speter of cases. If in doubt, do not point :include: aliases at 450638032Speter NFS-mounted filesystems. 450738032Speter SECURITY: When setting a numeric group id using the RunAsUser option 450838032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 450938032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 451038032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 451138032Speter The user id was still set properly. Problem noted by Uli 451238032Speter Pralle of the Technical University of Berlin. 451338032Speter Save the initial gid set for use when checking for if the 451438032Speter PrivacyOptions=restrictmailq option is set. Problem reported 451538032Speter by Wolfgang Ley of DFN-CERT. 451638032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 451738032Speter failure on one message won't affect future messages to the 451838032Speter same host). 451938032Speter IP source route printing had an "off by one" error that would 452038032Speter affect any options that came after the route option. Patch 452138032Speter from Theo de Raadt. 452238032Speter The "Message is too large" error didn't successfully bounce the error 452338032Speter back to the sender. Problem reported by Stephen More of 452438032Speter PSI; patch from Gregory Neil Shapiro of WPI. 452538032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 452638032Speter of 5.1.3); it apparently gets used in multiple ways. 452738032Speter Suggested by John Myers of Portola Communications. 452838032Speter Fix possible extra null byte generated during collection if errors 452938032Speter occur at the beginning of the stream. Patch contributed by 453038032Speter Andrey A. Chernov and Gregory Neil Shapiro. 453138032Speter Code changes to avoid possible reentrant call of malloc/free within 453238032Speter a signal handler. Problem noted by John Beck of Sun 453338032Speter Microsystems. 453438032Speter Move map initialization to be earlier so that check_relay ruleset 453538032Speter will have the latest version of the map data. Problem noted 453638032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 453738032Speter If there are fatal errors during the collection phase (e.g., message 453838032Speter too large) don't send the bogus message. 453938032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 454038032Speter have errors and have owner- aliases. Problem noted by Michael 454138032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 454238032Speter Avoid null pointer dereference on illegal Boundary= parameters in 454338032Speter multipart/mixed Content-Type: header. Problem noted by 454438032Speter Richard Muirden of RMIT University. 454538032Speter Always print error messages during newaliases (-bi) even if the 454638032Speter ErrorMode is not set to "print". Fix from Gregory Neil 454738032Speter Shapiro. 454838032Speter Test mode could core dump if you did a /map lookup in an optional map 454938032Speter that could not be opened. Based on a fix from John Beck of 455038032Speter Sun Microsystems. 455138032Speter If DNS is misconfigured so that the last MX record tried points to 455238032Speter a host that does not have an A record, but other MX records 455338032Speter pointed to something reasonable, don't bounce the message 455438032Speter with a "host unknown" error. Note that this should really 455538032Speter be fixed in the zone file for the domain. Problem noted by 455638032Speter Joe Rhett of Navigist, Inc. 455738032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 455838032Speter the message as having been tried; otherwise the next queue 455938032Speter run will not realize that this is a second attempt and will 456038032Speter retry immediately. Problem noted by Bryan Costales of 456138032Speter Mercury Mail. 456238032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 456338032Speter will be run until the later setting of the clock is reached. 456438032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 456538032Speter Morgan Stanley. 456638032Speter If the load average rises above the cutoff threshold (above which 456738032Speter sendmail will not process the queue at all) during a queue 456838032Speter run, abort the queue run immediately. Problem noted by 456938032Speter Bryan Costales of Mercury Mail. 457038032Speter The variable queue processing algorithm (based on the message size, 457138032Speter number of recipients, message precedence, and job age) was 457238032Speter non-functional -- either the entire queue was processed or 457338032Speter none of the queue was processed. The updated algorithm 457438032Speter does no queue run if a single recipient zero size job will 457538032Speter not be run. 457638032Speter If there is a fatal ("panic") message that will cause sendmail to 457738032Speter die immediately, never hold the error message for future 457838032Speter printing. 457938032Speter Force ErrorMode=print in -bt mode so that all errors are printed 458038032Speter regardless of the setting of the ErrorMode option in the 458138032Speter configuration file. Patch from Gregory Neil Shapiro. 458238032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 458338032Speter routine available in one of the libraries. Use it in conf.h. 458438032Speter The -m (match only) flag now works on host class maps. 458538032Speter If class hash or btree maps are rebuilt, sendmail will now detect 458638032Speter this and reopen the map. Previously, they could give 458738032Speter erroneous results during a single message processing 458838032Speter (but would recover when the next message was received). 458938032Speter Don't delete zero length queue files when doing queue runs until the 459038032Speter files are at least ten minutes old. This avoids a potential 459138032Speter race condition: the creator creates the qf file, getting back 459238032Speter a file descriptor. The queue runner locks it and deletes it 459338032Speter because it is zero length. The creator then writes the 459438032Speter descriptor that is now for a disconnected file, and the 459538032Speter job goes away. Based on a suggestion by Bryan Costales. 459638032Speter When determining the "validated" host name ($_ macro), do a forward 459738032Speter (A) DNS lookup on the result of the PTR lookup and compare 459838032Speter results. If they differ or if the PTR lookup fails, tag the 459938032Speter address as "may be forged". 460038032Speter Log null connections (i.e., hosts that connect but do not do any 460138032Speter substantive activity on the connection before disconnecting; 460238032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 460338032Speter Always permit "writes" to /dev/null regardless of the link count. 460438032Speter This is safe because /dev/null is special cased, and no open 460538032Speter or write is ever actually attempted. Patch from Villy Kruse 460638032Speter of TwinCom. 460738032Speter If a message cannot be sent because of a 552 (exceeded storage 460838032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 460938032Speter was given, don't return the body in the bounce, since there 461038032Speter is a very good chance that the message will double-bounce. 461138032Speter Fix possible line truncation if a quoted-printable had an =00 escape 461238032Speter in the body. Problem noted by Charles Karney of the Princeton 461338032Speter Plasma Physics Laboratory. 461438032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 461538032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 461638032Speter Institute. 461738032Speter The MaxDaemonChildren option wasn't applying to queue runs as 461838032Speter documented. Note that this increases the potential denial 461938032Speter of service problems with this option: an attacker can 462038032Speter connect many times, and thereby lock out queue runs as well 462138032Speter as incoming connections. If you use this option, you should 462238032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 462338032Speter to avoid this attack. Failure to limit noted by Matthew 462438032Speter Dillon of BEST Internet Communications. 462538032Speter Always give a message in newaliases if alias files cannot be 462638032Speter opened instead of failing silently. Suggested by Gregory 462738032Speter Neil Shapiro. This change makes the code match the O'Reilly 462838032Speter book (2nd edition). 462938032Speter Some older versions of the resolver could return with h_errno == -1 463038032Speter if no name server could be reached, causing mail to bounce 463138032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 463238032Speter John Beck of SunSoft. 463338032Speter If a :include: file is owned by a user that does not have an entry 463438032Speter in the passwd file, sendmail could dereference a null pointer. 463538032Speter Problem noted by Satish Mynam of Sun Microsystems. 463638032Speter Take precautions to make sure that the SMTP protocol cannot get out 463738032Speter of sync if (for example) an alias file cannot be opened. 463838032Speter Fix a possible race condition that can cause a SIGALRM to come in 463938032Speter immediately after a SIGHUP, causing the new sendmail to die. 464038032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 464138032Speter from Villy Kruse of TwinCom. 464238032Speter Ignore improperly formatted SMTP reply codes. Previously these were 464338032Speter partially processed, which could cause confusing error 464438032Speter returns. 464538032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 464638032Speter on some architectures. 464738032Speter Portability: 464838032Speter A/UX: from Jim Jagielski of NASA/GSFC. 464938032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 465038032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 465138032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 465238032Speter defined. Problem reported by A Sun of the University 465338032Speter of Washington. 465438032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 465538032Speter the system rather than guessing at compile time. 465638032Speter Patch contributed by John Beck of Sun Microsystems. 465738032Speter Intel Paragon: from Wendy Lin of Purdue University. 465838032Speter GNU Hurd: from Miles Bader of the GNU project. 465938032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 466038032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 466138032Speter Unfortunately releasing them opens a race condition, 466238032Speter but there appears to be no fix for this. Patch from 466338032Speter Gregory Neil Shapiro. 466438032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 466538032Speter Solaris: a bug in strcasecmp caused characters with the 466638032Speter high order bit set to apparently randomly match 466738032Speter letters -- for example, $| (0233) matches "i" and "I". 466838032Speter Problem noted by John Gregson of the University of 466938032Speter Cambridge. 467038032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 467138032Speter Kari Hurtta. 467238032Speter IRIX 6.x: Create Makefiles for systems that claim to be 467338032Speter IRIX64 but are 6.2 or higher (so use the regular 467438032Speter IRIX Makefile). 467538032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 467638032Speter Problem noted by Eric Hagberg of Morgan Stanley. 467738032Speter CONFIG: Some canonification was still done for UUCP-like addresses 467838032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 467938032Speter Brian Candler. 468038032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 468138032Speter local names as local. Problem noted by Jeff Polk of BSDI; 468238032Speter fix provided by Gregory Neil Shapiro. 468338032Speter CONFIG: The "local:user" syntax entries in mailertables and other 468438032Speter "mailer:user" syntax locations returned an incorrect value 468538032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 468638032Speter CONFIG: Retain "+detail" information when forwarding mail to a 468738032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 468838032Speter Guenther of Gustavus Adolphus College. 468938032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 469038032Speter rules are the same as for aliasing. Based on a patch from 469138032Speter Gregory Neil Shapiro. 469238032Speter CONFIG: Break up parsing rules into several pieces; this should 469338032Speter have no functional change in this release, but makes it 469438032Speter possible to have better anti-spam rulesets in the future. 469538032Speter CONFIG: Disallow double dots in host names to avoid having the 469638032Speter HostStatusDirectory store status under the wrong name. 469738032Speter In some cases this can be used as a denial-of-service attack. 469838032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 469938032Speter Gregory Neil Shapiro. 470038032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 470138032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 470238032Speter don't include From_, and convert to 8-bit). Suggestions 470338032Speter from Kimmo Suominen and Roderick Schertler. 470464562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 470538032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 470638032Speter was specified, even when it wasn't. 470738032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 470838032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 470938032Speter "slip in" a symbolic link between the lstat(2) call and the 471038032Speter exclusive open. This is only a problem on System V derived 471138032Speter systems that allow an exclusive create on files that are 471238032Speter symbolic links pointing nowhere. 471338032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 471438032Speter not reset back to root, which on some systems would cause 471538032Speter later mailboxes to fail. Also, any partial message would 471638032Speter not be truncated, which could result in repeated deliveries. 471738032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 471838032Speter developers). 471938032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 472038032Speter change to the sendmail map code was made in 8.8.3. Problem 472138032Speter noted by Gregory Neil Shapiro. 472238032Speter MAKEMAP: Give warnings on file problems such as map files that are 472390792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 472438032Speter often run as root and hence has the potential for the same 472538032Speter sorts of problems as alias rebuilds. 472638032Speter MAKEMAP: Change compilation so that it will link properly on 472738032Speter NEXTSTEP. 472838032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 472938032Speter Accept an optional list of arguments following the server 473038032Speter name for the ETRN arguments to use (instead of $=w).

This 473438032Speter Perl script converts GECOS information in the /etc/passwd 473538032Speter file into aliases, allowing for faster access to full name 473638032Speter lookups; it is also clever about adding aliases (to root) 473738032Speter for system accounts. 473838032Speter NEW FILES: 473938032Speter src/safefile.c 474038032Speter cf/ostype/gnuhurd.m4 474138032Speter cf/ostype/irix6.m4 474238032Speter contrib/passwd-to-alias.pl 474338032Speter src/Makefiles/Makefile.IRIX64.6.1 474438032Speter src/Makefiles/Makefile.IRIX64.6.x 474538032Speter RENAMED FILES: 474638032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 474738032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 474838032Speter 474964562Sgshapiro8.8.5/8.8.5 1997/01/21 475038032Speter SECURITY: Clear out group list during startup. Without this, sendmail 475138032Speter will continue to run with the group permissions of the caller, 475238032Speter even if RunAsUser is specified. 475338032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 475438032Speter to any known attack, but it's best to be conservative. 475538032Speter Suggested by Peter Wemm of DIALix. 475638032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 475738032Speter security implications. Patch from Alex Garthwaite of the 475838032Speter University of Pennsylvania. 475938032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 476038032Speter would truncate the address after "Full". Although the -f 476138032Speter syntax is incorrect (since it is in the envelope, it 476238032Speter shouldn't have comments and full names), the failure mode 476338032Speter was unnecessarily awful. 476438032Speter Fix a possible null pointer dereference when converting 8-bit data 476538032Speter to a 7-bit format. Problem noted by Jim Hutchins of 476638032Speter Sandia National Labs and David James of British Telecom. 476738032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 476838032Speter runs. Although this really shouldn't be used (F=9 is for 476938032Speter final delivery only, and using it on an SMTP mailer makes 477038032Speter it possible for a message to be converted from 8->7->8->7 477138032Speter bits several times), it shouldn't have failed with a syserr. 477238032Speter Problem noted by Eric Hagberg of Morgan Stanley. 477338032Speter _Really_ fix the multiple :maildrop code in the user database 477438032Speter module. Patch from Roy Mongiovi of Georgia Tech. 477538032Speter Let F lines in the configuration file actually read root-only 477638032Speter files if the configuration file is safe. Based on a 477738032Speter patch from Keith Reynolds of SCO. 477838032Speter ETRN followed by QUIT would hold the connection open until the queue 477938032Speter run completed. Problem noted by Truck Lewis of TDK 478038032Speter Semiconductor Corp. 478138032Speter It turns out that despite the documentation, the TCP wrappers library 478238032Speter does _not_ log rejected connections. Do the logging ourselves. 478338032Speter Problem noted by Fletcher Mattox of the University of Texas 478438032Speter at Austin. 478538032Speter If sendmail finds a qf file in its queue directory that is an unknown 478638032Speter version (e.g., when backing out to an old version), the 478738032Speter error is reported on every queue run. Change it to only 478838032Speter give the error once (and rename the qf => Qf). Patch from 478938032Speter William A. Gianopoulos of Raytheon Company. 479038032Speter Start a new session when doing background delivery; currently it 479138032Speter ignored signals but didn't start a new signal, that caused 479238032Speter some problems if a background process tried to send mail 479338032Speter under certain circumstances. Problem noted by Eric Hagberg 479438032Speter of Morgan Stanley; fix from Kari Hurtta. 479538032Speter Simplify test for skipping a queue run to just check if the current 479638032Speter load average is >= the queueing load average. Previously 479738032Speter the check factored in some other parameters that caused it 479838032Speter to essentially never skip the queue run. Patch from Bryan 479938032Speter Costales. 480038032Speter If the SMTP server is running in "nullserver" mode (that is, it is 480138032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 480238032Speter (25) commands; this helps prevent a bad guy from putting 480338032Speter you into a tight loop as a denial-of-service attack. Based 480438032Speter on an e-mail conversation with Brad Knowles of AOL. 480538032Speter Slow down when too many "light weight" commands have been issued; 480638032Speter this helps prevent a class of denial-of-service attacks. 480738032Speter The current values and defaults are: 480838032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 480938032Speter MAXHELOCOMMANDS 3 HELO, EHLO 481038032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 481138032Speter MAXETRNCOMMANDS 8 ETRN 481238032Speter These will probably be configurable in a future release. 481338032Speter On systems that have uid_t typedefed to be an unsigned short, programs 481438032Speter that had the F=S flag and no U= equate would be invoked with 481538032Speter the real uid set to 65535 rather than being left unchanged. 481638032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 481738032Speter by Steve Hubert of the University of Washington, Seattle. 481838032Speter Mail that was Quoted-Printable encoded and had a soft line break on 481938032Speter the last line (i.e., an incomplete continuation) had the last 482038032Speter line dropped. Since this appears to be illegal it isn't 482138032Speter clear what to do with it, but flushing the last line seems 482238032Speter to be a better "fail soft" approach. Based on a patch from 482338032Speter Eric Hagberg. 482438032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 482538032Speter bogus HELO command still causes the "Polite people say HELO 482638032Speter first" error message. Problem pointed out by Chris Thomas 482738032Speter of UCLA; patch from John Beck of SunSoft. 482838032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 482971345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 483071345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 483171345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 483238032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 483338032Speter in a DATA transaction to be sticky; these can occur because 483438032Speter a message is too large, and smaller messages should still go 483538032Speter through. Problem noted by Matt Dillon of Best Internet 483638032Speter Communications. 483738032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 483838032Speter had been successfully delivered to the envelope sender. 483938032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 484038032Speter Gregory Neil Shapiro of WPI. 484138032Speter Give better diagnostics on long alias lines. Based on code contributed 484238032Speter by Patrick Gosling of the University of Cambridge. 484338032Speter Increase the number of virtual interfaces that will be probed for 484438032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 484538032Speter PORTABILITY: 484638032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 484738032Speter Toshiaki Nomura of Fujitsu Limited. 484838032Speter SunOS with LDAP support: compile problems with struct timeval. 484938032Speter Patch from Nick Cuccia of TCSI Corporation. 485038032Speter SCO: from Keith Reynolds of SCO. 485138032Speter Solaris: kstat load average computation wasn't being used. 485238032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 485338032Speter (Moscow). 485438032Speter OpenBSD: from Jason Downs of teeny.org. 485538032Speter Altos System V: from Tim Rice. 485638032Speter Solaris 2.5: from Alan Perry of SunSoft. 485738032Speter Solaris 2.6: from John Beck of SunSoft. 485838032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 485938032Speter of Pratt & Whitney <miorelli@pweh.com>. 486038032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 486138032Speter _just_right_ yet. Tweak it again. I'll omit the names 486238032Speter of the "contributors" (quantity two) in this one case. 486338032Speter As of now, NO MORE DISCUSSION about the syntax of the 486438032Speter Received: line. 486538032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 486638032Speter it never inserts that class into the output file. Fix it 486738032Speter so it will honor EXPOSED_USER but will _not_ include root 486838032Speter automatically in this class. Problem noted by Ronan KERYELL 486938032Speter of Centre de Recherche en Informatique de l'�cole Nationale 487038032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 487138032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 487238032Speter such as LUSER_RELAY. This change permits the following 487338032Speter syntaxes: ``local:'' will send to the same user on the 487438032Speter local machine (e.g., in a mailertable entry for "host", 487538032Speter ``local:'' will cause an address addressed to user@host to 487638032Speter go to user on the local machone). ``local:user'' will send 487738032Speter to the named user on the local machine. ``local:user@host'' 487838032Speter is equivalent to ``local:user'' (the host is ignored). In 487938032Speter all cases, the original user@host is passed in $@ (i.e., the 488038032Speter detail information). Inspired by a report from Michael Fuhr. 488138032Speter CONFIG: Strip quotes from the first word of an "error:" host 488238032Speter indication. This lets you set (for example) the LUSER_RELAY 488338032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 488438032Speter of the \" so that the resulting string is properly quoted. 488538032Speter Problem noted by Gregory Neil Shapiro of WPI. 488638032Speter OP.ME: documentation was inconsistent about whether sendmail did a 488738032Speter NOOP or a RSET to probe the connection (it does a RSET). 488838032Speter Inconsistency noted by Deeran Peethamparam. 488938032Speter OP.ME: insert additional blank pages so it will print properly on 489038032Speter a duplex printer. From Matthew Black of Cal State University, 489138032Speter Long Beach. 489238032Speter 489364562Sgshapiro8.8.4/8.8.4 1996/12/02 489438032Speter SECURITY: under some circumstances, an attacker could get additional 489538032Speter permissions by hard linking to files that were group 489638032Speter writable by the attacker. The solution is to disallow any 489738032Speter files that have hard links -- this will affect .forward, 489838032Speter :include:, and output files. Problem noted by Terry 489938032Speter Kyriacopoulos of Interlog Internet Services. As a 490038032Speter workaround, set UnsafeGroupWrites -- always a good idea. 490138032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 490238032Speter is, it is possible to do a denial-of-service attack on 490338032Speter MX hosts that rely on the use of the null MX list. There 490438032Speter is no danger if you have this option turned off (the default). 490538032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 490638032Speter unsafe. I know of no specific attack against this, although 490738032Speter a denial-of-service attack is probably possible, but in theory 490838032Speter you should not be able to safely tweak anything that affects 490938032Speter the permissions that are used when mail is delivered. 491038032Speter Purgestat could go into an infinite loop if one of the host status 491138032Speter directories somehow became empty. Problem noted by Roy 491238032Speter Mongiovi of Georgia Tech. 491338032Speter Processes got "lost" when counting children due to a race condition. 491438032Speter This caused "proc_list_probe: lost pid" messages to be logged. 491538032Speter Problem noted by several people. 491638032Speter On systems with System V SIGCLD child signal semantics (notably AIX 491738032Speter and HP-UX), mail transactions would print the message "451 491838032Speter SMTP-MAIL: lost child: No child processes". Problem noted 491938032Speter by several people. 492038032Speter Miscellaneous compiler warnings on picky compilers (or when setting 492138032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 492238032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 492338032Speter not be persistent between runs, since they are based on the 492438032Speter message rather than the host. Problem noted by Matt Dillon 492538032Speter of Best Internet Communications. 492638032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 492738032Speter of NCR (a.k.a., AT&T Global Information Solutions). 492838032Speter Avoid the possibility of having a child daemon run to completion 492938032Speter (including closing the SMTP socket) before the parent has 493038032Speter had a chance to close the socket; this can cause the parent 493138032Speter to hang for a long time waiting for the socket to drain. 493238032Speter Patch from Don Lewis of TDK Semiconductor. 493338032Speter If the fork() failed in a queue run, the queue runners would not be 493438032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 493538032Speter Some error conditions in ETRN could cause output without an SMTP 493638032Speter status code. Problem noted by Don Lewis. 493738032Speter Multiple :maildrop addresses in the user database didn't work properly. 493838032Speter Patch from Roy Mongiovi of Georgia Tech. 493938032Speter Add ".db" automatically onto any user database spec that does not 494038032Speter already have it; this is for consistency with makemap, the 494138032Speter K line, and the documentation. Inconsistency pointed out 494238032Speter by Roy Mongiovi. 494338032Speter Allow sendmail to be properly called in nohup mode. Patch from 494438032Speter Kyle Jones of UUNET. 494538032Speter Change ETRN to ignore but still update host status files; previously 494638032Speter it would ignore them and not save the updated status, which 494738032Speter caused stale information to be maintained. Based on a patch 494838032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 494938032Speter ETRN ignore the MinQueueAge option. 495038032Speter Patch long term host status to recover more gracefully from an empty 495138032Speter host status file condition. Patch from NAKAMURA Motonori 495238032Speter of Kyoto University. 495338032Speter Several patches to signal handling code to fix potential race 495438032Speter conditions from Don Lewis. 495538032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 495638032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 495738032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 495838032Speter compile flag; use NETINET instead. Solution based on a 495938032Speter patch from Bryan Costales. 496038032Speter PORTABILITY FIXES: 496138032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 496238032Speter /etc/security/passwd file when called as root. This 496338032Speter is very slow on some systems. To speed it up, use the 496438032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 496538032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 496638032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 496738032Speter Glicker of Burrelle's Information Service. 496838032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 496938032Speter from Makoto MATSUSHITA of Osaka University. 497038032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 497138032Speter Leeds University and SASABE Tetsuro of the University 497238032Speter of Tokyo. 497338032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 497438032Speter Services, Inc. 497538032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 497638032Speter I believe this to have only been a problem if you 497738032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 497838032Speter to stick with /etc/sendmail.cf as your One True Path. 497938032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 498038032Speter Martin Laubach of the Technischen Universit�t Wien. 498138032Speter CONFIG: change default Received: line to be multiple lines rather 498238032Speter than one long one. By popular demand. 498338032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 498438032Speter from Jerome Berkman of U.C. Berkeley. 498538032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 498638032Speter to take a very long time. Problem noted by Yoshiro YONEYA 498738032Speter of NTT Software Corporation. 498838032Speter CONTRIB: add etrn.pl, contributed by John Beck. 498938032Speter NEW FILES: 499038032Speter contrib/etrn.pl 499138032Speter 499264562Sgshapiro8.8.3/8.8.3 1996/11/17 499338032Speter SECURITY: it was possible to get a root shell by lying to sendmail 499438032Speter about argv[0] and then sending it a signal. Problem noted 499538032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 499638032Speter best-of-security list. 499738032Speter Log sendmail binary version number in "Warning: .cf version level 499838032Speter (%d) exceeds program functionality (%d) message" -- this 499938032Speter should make it clearer to people that they are running 500038032Speter the wrong binary. 500138032Speter Fix a problem that occurs when you open an SMTP connection and then 500238032Speter do one or more ETRN commands followed by a MAIL command; at 500338032Speter the end of the DATA phase sendmail would incorrectly report 500438032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 500538032Speter noted by Eric Bishop of Virginia Tech. 500638032Speter When doing text-based host canonification (typically /etc/hosts 500738032Speter lookup), a null host name would match any /etc/hosts entry 500838032Speter with space at the end of the line. Problem noted by Steve 500938032Speter Hubert of the University of Washington, Seattle. 501038032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 501138032Speter Problem reported by Tom Smith of Digital Equipment Corp. 501238032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 501338032Speter size PACKETSZ (512) is not sufficient for some nameserver 501438032Speter answers containing very many resource records. The resolver 501538032Speter may also switch to TCP and retry if it detects UDP packet 501638032Speter overflow. Also, allow for the fact that the resolver 501738032Speter routines res_query and res_search return the size of the 501838032Speter *un*truncated answer in case the supplied answer buffer it 501938032Speter not big enough to accommodate the entire answer. Patch from 502038032Speter Eric Wassenaar. 502138032Speter Improvements to MaxDaemonChildren code. If you think you have too 502238032Speter many children, probe the ones you have to verify that they 502338032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 502438032Speter Also, do this probe before growing the vector of children 502538032Speter pids; this previously caused the vector to grow indefinitely 502638032Speter due to a race condition. Problem reported by Kyle Jones of 502738032Speter UUNET. 502838032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 502938032Speter O_EXLOCK to zero; this fools the map compilation code into 503038032Speter thinking that it can avoid race conditions by locking on open. 503138032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 503238032Speter Leif Erlingsson of Data Lege. 503338032Speter Always call res_init() on startup (if compiled in, of course) to 503438032Speter allow the sendmail.cf file to tweak resolver flags; without 503538032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 503638032Speter Andrew Sun of Merrill Lynch. 503738032Speter Improvements to host status printing code. Suggested by Steve Hubert 503838032Speter of the University of Washington, Seattle. 503938032Speter Change MinQueueAge option processing to do the check for the job age 504038032Speter when reading the queue file, rather than at the end; this 504138032Speter avoids parsing the addresses, which can do DNS lookups. 504238032Speter Problem noted by John Beck of InReference, Inc. 504338032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 504438032Speter properly escaped. Problem noted by Peter Nilsson of the 504538032Speter University of Linkoping. 504638032Speter In some cases, sendmail would retain root permissions during queue 504738032Speter runs even if RunAsUser was set. Problem noted by Mark 504838032Speter Thomas of Mark G. Thomas Consulting. 504938032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 505038032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 505138032Speter the envelope, and the receiving SMTP server speaks DSN, then 505238032Speter the DSN would be both generated locally and propagated to the 505338032Speter other end. 505438032Speter The U= mailer field didn't correctly extract the group id if the 505538032Speter user id was numeric. Problem noted by Kenneth Herron of 505638032Speter MCI Telecommunications Communications. 505738032Speter If a message exceeded the fixed maximum size on input, the body of 505838032Speter the message was included in the bounce. Note that this did 505938032Speter not occur if it exceeded the maximum _output_ size. Problem 506038032Speter reported by Kyle Jones of UUNET. 506138032Speter PORTABILITY FIXES: 506238032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 506338032Speter AIX4 defines to use seteuid(2) instead, which 506438032Speter works on 4.1 as well as 4.2. Problem noted by 506538032Speter H�kan Lindholm of interAF, Sweden. 506638032Speter AIX4: use tzname[] vector to determine time zone name. 506738032Speter Patch from NAKAMURA Motonori of Kyoto University. 506838032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 506938032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 507038032Speter Solaris: kstat(3k) support for retrieving the load average. 507138032Speter This adds the LA_KSTAT definition for LA_TYPE. 507238032Speter The outline of the implementation was contributed 507338032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 507438032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 507538032Speter declaration of struct rusage at the top of conf.h; 507638032Speter change it to only be included if you are using gcc, 507738032Speter which is apparently the only compiler that requires 507838032Speter it in the first place. Problem noted by Jeff 507938032Speter Earickson of Colby College. 508038032Speter IRIX: don't default to using gcc. IRIX is a civilized 508138032Speter operating system that comes with a decent compiler 508238032Speter by default. Problem noted by Barry Bouwsma and 508338032Speter Kari Hurtta. 508438032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 508538032Speter consistency with other local mailers. Inconsistency 508638032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 508738032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 508838032Speter overhead) as part of the bestmx_is_local feature, the 508938032Speter domain part was dropped from the name. Patch from Steve 509038032Speter Hubert of the University of Washington, Seattle. 509138032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 509238032Speter end up being translated to the null host name, which would 509338032Speter return any entry in /etc/hosts that had a space at the end 509438032Speter of the line. Problem noted by Steve Hubert of the 509538032Speter University of Washington, Seattle. 509638032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 509738032Speter Polytechnic Institute. 509838032Speter MAKEMAP: tweak hash and btree parameters for better performance. 509938032Speter Patch from Matt Dillon of Best Internet Communications. 510038032Speter NEW FILES: 510138032Speter src/Makefiles/Makefile.Linux.ppc 510238032Speter cf/ostype/aix4.m4 510338032Speter cf/ostype/mklinux.m4 510438032Speter 510564562Sgshapiro8.8.2/8.8.2 1996/10/18 510638032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 510738032Speter changed the code but didn't fix the problem. 510838032Speter PORTABILITY FIXES: 510938032Speter Solaris: Don't use the system getusershell(3); it can 511038032Speter apparently corrupt the heap in some circumstances. 511138032Speter Problem found by Ken Pizzini of Spry, Inc. 511238032Speter OP.ME: document several mailer flags that were accidentally omitted 511338032Speter from this document.

Problem noted 511938032Speter by Dan Bernstein of the University of Illinois at Chicago. 512038032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 512138032Speter message could overflow a buffer if it was converted back 512238032Speter to 8 bits. This caused core dumps and has the potential 512338032Speter for a remote attack. Problem first noted by Gregory Shapiro 512438032Speter of WPI. 512538032Speter Avoid duplicate deliveries of error messages on systems that don't 512638032Speter have flock(2) support. Patch from Motonori Nakamura of 512738032Speter Kyoto University. 512838032Speter Ignore null FallBackMX (V) options. If this option is null (as 512938032Speter opposed to undefined) it can cause "null signature" syserrs 513038032Speter on illegal host names. 513138032Speter If a Base64 encoded text/plain message has no trailing newline in 513238032Speter the encoded text, conversion back to 8 bits will drop the 513338032Speter final line. Problem noted by Pierre David. 513438032Speter If running with a RunAsUser, sendmail would give bogus "cannot 513538032Speter setuid" (or seteuid, or setreuid) messages on some systems. 513638032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 513738032Speter Always print error messages in -bv mode -- previously, -bv would 513838032Speter be absolutely silent on errors if the error mode was sent 513938032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 514038032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 514138032Speter term host status. This is necessary because it is common 514238032Speter to do this when you know a host has just come back up. 514338032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 514438032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 514538032Speter University of Leicester. 514638032Speter If a service (such as NIS) is specified as the last entry in the 514738032Speter service switch, but that service is not compiled in, sendmail 514838032Speter would return a temporary failure when an entry was not found 514938032Speter in the map. This caused the message to be queued instead of 515038032Speter bouncing immediately. Problem noted by Harry Edmon of the 515138032Speter University of Washington. 515238032Speter PORTABILITY FIXES: 515338032Speter Solaris 2.3 had compilation problems in conf.c. Several 515438032Speter people pointed this out. 515538032Speter NetBSD from Charles Hannum of MIT. 515638032Speter AIX4 improvements based on info from Steve Bauer of South 515738032Speter Dakota School of Mines & Technology. 515838032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 515938032Speter Patch from Gil Kloepfer Jr. 516038032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 516138032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 516238032Speter were also in $=w. Problem noted by Zoltan Basti of 516338032Speter Softec. 516438032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 516538032Speter on a patch from Eric Hagberg of Morgan Stanley. 516638032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 516738032Speter of Stanford via Robert La Ferla. 516838032Speter 516964562Sgshapiro8.8.0/8.8.0 1996/09/26 517038032Speter Under some circumstances, Bcc: headers would not be properly 517138032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 517238032Speter Log a warning if the sendmail daemon is invoked without a full 517338032Speter pathname, which prevents "kill -1" from working. I was 517438032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 517538032Speter Fix small buffer overflow. Since the data in this buffer was not 517638032Speter read externally, there was no security problem (and in fact 517738032Speter probably wouldn't really overflow on most compilers). Pointed 517838032Speter out by KIZU takashi of Osaka University. 517938032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 518038032Speter if a FallbackMXHost was specified in the configuration file 518138032Speter -- all mail would be sent to the fallback even if the original 518238032Speter host was accessible. Pointed out by Munenari Hirayama of 518338032Speter NSC (Japan). 518438032Speter A message that didn't terminate with a newline would (sometimes) not 518538032Speter have the trailing "." added properly in the SMTP dialogue, 518638032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 518738032Speter The DaemonPortOptions suboption to bind to a particular address was 518838032Speter incorrect and nonfunctional due to a misunderstanding of the 518938032Speter semantics of binding on a passive socket. Patch from 519038032Speter NIIBE Yutaka of Mitsubishi Research Institute. 519138032Speter Increase the number of MX hosts for a single name to 100 to better 519238032Speter handle the truly huge service providers such as AOL, which 519338032Speter has 13 at the moment (and climbing). In order to avoid 519438032Speter trashing memory, the buffer for all names has only been 519538032Speter slightly increased in size, to 12.8K from 10.2K -- this means 519638032Speter that if a single name had 100 MX records, the average size 519738032Speter of those records could not exceed 128 bytes. Requested by 519838032Speter Brad Knowles of America On Line. 519938032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 520038032Speter Urged by Dan Bernstein of U.C. Berkeley. 520138032Speter Print q_statdate and q_specificity in address structure debugging 520238032Speter printout. 520338032Speter Expand MCI structure flag bits for debugging output. 520438032Speter Support IPv6-style domain literals, which can have colons between 520538032Speter square braces. 520638032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 520738032Speter this is an attempt to track down a bug that one person seems 520838032Speter to be having (it may be a Solaris bug!). 520938032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 521038032Speter this caused the NOTIFY info to sometimes be lost. Problem 521138032Speter pointed out by Claus Assmann of the 521238032Speter Christian-Albrechts-University of Kiel. 521338032Speter The statistics gathered in the sendmail.st file were too high; in 521438032Speter some cases failures (e.g., user unknown or temporary failure) 521538032Speter would count as a delivery as far as the statistics were 521638032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 521738032Speter Systems that don't have flock() would not send split envelopes in 521838032Speter the initial run. Problem pointed out by Leonard Zubkoff of 521938032Speter Dandelion Digital. 522038032Speter Move buffer overflow checking -- these primarily involve distrusting 522138032Speter results that may come from NIS and DNS. 522238032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 522338032Speter include <paths.h> and hence had the wrong pathnames for a few 522438032Speter things like /var/tmp. Reported by Matthew Green. 522538032Speter Conditions were reversed for the Priority: header, resulting in all 522638032Speter values being interpreted as non-urgent except for non-urgent, 522738032Speter which was interpreted as normal. Patch from Bryan Costales. 522838032Speter The -o (optional) flag was being ignored on hash and btree maps 522938032Speter since 8.7.2. Fix from Bryan Costales. 523038032Speter Content-Types listed in class "q" will always be encoded as 523138032Speter Quoted-Printable (or more accurately, will never be encoded 523238032Speter as base64). The class can have primary types (e.g., "text") 523338032Speter or full types (e.g., "text/plain"). Based on a suggestion by 523438032Speter Marius Olafsson of the University of Iceland. 523538032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 523638032Speter dialogue) so it can be passed to programs in mailers. 523738032Speter Define ${bodytype} to be the body type (from the -B flag or the 523838032Speter BODY= ESMTP parameter) so it can be passed to programs in 523938032Speter mailers. 524038032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 524138032Speter flag is set in the mailer descriptor. Suggested by John 524238032Speter Myers of CMU. 524338032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 524438032Speter The command takes a host name; data for that host is 524538032Speter immediately (and asynchronously) flushed. Because this shares 524638032Speter the -qR implementation, other hosts may be attempted, but 524738032Speter there should be no security implications. Implementation 524838032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 524938032Speter Add three new command line flags to pass in DSN parameters: -V envid 525038032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 525138032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 525238032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 525338032Speter that the -N flag applies to all recipients; there is no way 525438032Speter to specify per-address notifications on the command line, 525538032Speter nor is there an equivalent for the ORCPT= per-address 525638032Speter parameter. 525738032Speter Restore LogLevel option to be safe (it can only be increased); 525838032Speter apparently I went into paranoid mode between 8.6 and 8.7 525938032Speter and made it unsafe. Pointed out by Dabe Murphy of the 526038032Speter University of Maryland. 526138032Speter New logging on log level 15: all SMTP traffic. Patches from 526238032Speter Andrew Gross of San Diego Supercomputer Center. 526338032Speter NetInfo property value searching code wasn't stopping when it found 526438032Speter a match. This was causing the wrong values to be found (and 526538032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 526638032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 526738032Speter out by Bill Wisner of Electronics for Imaging that you can't 526838032Speter use the bracket address form for the MAIL_HUB macro, since 526938032Speter that causes the brackets to remain in the envelope recipient 527038032Speter address used for delivery. The simple fix (stripping off the 527138032Speter brackets in the config file) breaks the use of IP literal 527238032Speter addresses. This flag will solve that problem. 527338032Speter Add MustQuoteChars option. This is a list of characters that must 527438032Speter be quoted if they are found in the phrase part of an address 527538032Speter (that is, the full name part). The characters @,;:\()[] are 527638032Speter always in this list and cannot be removed. The default is 527738032Speter this list plus . and ' to match RFC 822. 527838032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 527938032Speter that do not include a host name for back compatibility with 528038032Speter some stupid SMTP clients. Setting this violates RFC 1123 528138032Speter section 5.2.5. 528238032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 528338032Speter rejecting connections if it has more than this many 528438032Speter outstanding children accepting mail. Note that you may 528538032Speter see more processes than this because of outgoing mail; this 528638032Speter is for incoming connections only. 528738032Speter Add ConnectionRateThrottle option. If set to a positive value, the 528838032Speter number of incoming SMTP connections that will be permitted 528938032Speter in a single second is limited to this number. Connections are 529038032Speter not refused during this time, just deferred. The intent is to 529138032Speter flatten out demand so that load average limiting can kick in. 529238032Speter It is less radical than MaxDaemonChildren, which will stop 529338032Speter accepting connections even if all the connections are idle 529438032Speter (e.g., due to connection caching). 529538032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 529638032Speter specifies how long cached information about the state of a 529738032Speter host will be kept before they are considered stale and the 529838032Speter host is retried. If you are using persistent host status 529938032Speter (i.e., the HostStatusDirectory option is set) this will apply 530038032Speter between runs; otherwise, it applies only within a single queue 530138032Speter run and hence is useful only for hosts that have large queues 530238032Speter that take a very long time to run. 530338032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 530438032Speter into being a single line even if they had newlines in them 530538032Speter when read. This is to get around a botch in Lotus Notes. 530638032Speter Text class maps were totally broken -- if you ever retrieved the last 530738032Speter item in a table it would be truncated. Problem noted by 530838032Speter Gregory Neil Shapiro of WPI. 530938032Speter Extend the lines printed by the mailq command (== the -bp flag) when 531038032Speter -v is given to 120 characters; this allows more information 531138032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 531238032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 531338032Speter this was treated as end-of-input. Problem noted by Bryan 531438032Speter Costales. 531538032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 531638032Speter to the queue file. Fix from John Hughes of Atlantic 531738032Speter Technologies, Inc. 531838032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 531938032Speter if this happens in a queue run it can cause nasty delays. 532038032Speter Problem noted by Mark Horton of AT&T. 532138032Speter If userdb entries pointed to userdb entries, and there were multiple 532238032Speter values for a given key, the database cursor would get 532338032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 532438032Speter of Georgia Tech. Fixed by reading all the values and creating 532538032Speter a comma-separated list; thus, the -v output will be somewhat 532638032Speter different for this case. 532738032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 532838032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 532938032Speter of Stanford University. 533038032Speter When envelopes were split due to aliases with owner- aliases, and 533138032Speter there was some error on one of the lists, more than one of 533238032Speter the owners would get the message. Problem pointed out by 533338032Speter Roy Mongiovi of Georgia Tech. 533438032Speter Detect excessive recursion in macro expansions, e.g., $X defined 533538032Speter in terms of $Y which is defined in terms of $X. Problem 533638032Speter noted by Bryan Costales; patch from Eric Wassenaar. 533738032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 533838032Speter some cases get trashed causing bogus From_ lines. Fix from 533938032Speter Kyle Jones of UUNET. 534038032Speter When doing load average initialization, if the nlist call for avenrun 534138032Speter failed, the second and subsequent lookups wouldn't notice 534238032Speter that fact causing bogus load averages to be returned. Noted 534338032Speter by Casper Dik of Sun Holland. 534438032Speter Fix problem with incompatibility with some versions of inet_aton that 534538032Speter have changed the return value to unsigned, so a check for an 534638032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 534738032Speter This could cause mail to addresses such as [foo.com] to bounce 534838032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 534938032Speter Pasteur Institute. 535038032Speter DSNs were inconsistent if a failure occurred during the DATA phase 535138032Speter rather than the RCPT phase: the Action: would be correct, but 535238032Speter the detailed status information would be wrong. Problem noted 535338032Speter by Bob Snyder of General Electric Company. 535438032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 535538032Speter that this is the initial MUA->MTA submission. The flag current 535638032Speter does nothing, but in future releases (when MUAs start using 535738032Speter these flags) it will probably turn on things like DNS 535838032Speter canonification. 535938032Speter Default end-of-line string (E= specification on mailer [M] lines) 536038032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 536138032Speter mailers. 536238032Speter Change the internal definition for the *file* and *include* mailers 536338032Speter to have $u in the argument vectors so that they aren't 536438032Speter misinterpreted as SMTP mailers and thus use \r\n line 536538032Speter termination. This will affect anyone who has redefined 536638032Speter either of these in their configuration file. 536738032Speter Don't assume that IDENT servers close the connection after a query; 536838032Speter responses can be newline terminated. From Terry Kennedy of 536938032Speter St. Peter's College. 537038032Speter Avoid core dumps on erroneous configuration files that have 537138032Speter $#mailer with nothing following. From Bryan Costales. 537238032Speter Avoid null pointer dereference with high debug values in unlockqueue. 537338032Speter Fix from Randy Martin of Clemson University. 537438032Speter Fix possible buffer overrun when expanding very large macros. Fix 537538032Speter from Kyle Jones of UUNET. 537638032Speter After 25 EXPN or VRFY commands, start pausing for a second before 537738032Speter processing each one. This avoids a certain form of denial 537838032Speter of service attack. Potential attack pointed out by Bryan 537938032Speter Costales. 538038032Speter Allow new named (not numbered!) config file rules to do validity 538138032Speter checking on SMTP arguments: check_mail for MAIL commands and 538238032Speter check_rcpt for RCPT commands. These rulesets can do anything 538338032Speter they want; their result is ignored unless they resolve to the 538438032Speter $#error mailer, in which case the indicated message is printed 538538032Speter and the command is rejected. Similarly, the check_compat 538638032Speter ruleset is called before delivery with "from_addr $| to_addr" 538738032Speter (the $| is a meta-symbol used to separate the two addresses); 538838032Speter it can give a "this sender can't send to this recipient" 538938032Speter notification. Note that this patch allows $| to stand alone 539038032Speter in rulesets. 539138032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 539238032Speter that have the name, IP address, and port number (respectively) 539338032Speter of the SMTP client (that is, the entity at the other end of 539438032Speter the connection. These can be used in (e.g.) check_rcpt to 539538032Speter verify that someone isn't trying to relay mail through your 539638032Speter host inappropriately. Be sure to use the deferred evaluation 539738032Speter form, for example $&{client_name}, to avoid having these bound 539838032Speter when sendmail reads the configuration file. 539938032Speter Add new config file rule check_relay to check the incoming connection 540038032Speter information. Like check_compat, it is passed the host name 540138032Speter and host address separated by $| and can reject connections 540238032Speter on that basis. 540338032Speter Allow IDA-style recursive function calls. Code contributed by Mark 540438032Speter Lovell and Paul Vixie. 540538032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 540638032Speter a virtual UUCP address using either a domain address or the $k 540738032Speter macro. Based on code contributed by Mark Lovell and Paul 540838032Speter Vixie. 540938032Speter Add Stanford LDAP map. Requires special libraries that are not 541038032Speter included with sendmail. Contributed by Booker C. Bense 541138032Speter <bbense@networking.stanford.edu>; contact him for support. 541238032Speter See also the src/READ_ME file. 541338032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 541438032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 541538032Speter only for debugging deep bits of code where it is important to 541638032Speter distinguish between the single-character metasymbol $+ and the 541738032Speter two characters $, +. 541838032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 541938032Speter debug_dumpstate. 542038032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 542138032Speter files that are group writable are considered "unsafe" -- that 542238032Speter is, programs and files referenced from such files are not 542338032Speter valid recipients. 542438032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 542538032Speter name that was not in DNS or was a domain-literal. Problem 542638032Speter noted by Tom May. 542738032Speter Change the introduction to error messages to more clearly delineate 542838032Speter permanent from temporary failures; if both existed in a 542938032Speter single message it could be confusing. Suggested by John 543038032Speter Beck of InReference, Inc. 543138032Speter The IngoreDot (i) option didn't work for lines that were terminated 543238032Speter with CRLF. Problem noted by Ted Stockwell of Secure 543338032Speter Computing Corporation. 543438032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 543538032Speter message headers. Problem reported by Matt Dillon of Best 543638032Speter Internet Communications. 543738032Speter Check for bogus characters in the 0200-0237 range; since these are 543838032Speter used internally, very strange errors can occur if those 543938032Speter characters appear in headers. Problem noted by Anders Gertz 544038032Speter of Lysator. 544138032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 544238032Speter recipient mailer has the F=9 flag set, and only works on 544338032Speter text/plain body types. Code contributed by Marius Olafsson 544438032Speter of the University of Iceland. 544538032Speter Special case "postmaster" name so that it is always treated as lower 544638032Speter case in alias files regardless of configuration settings; 544738032Speter this prevents some potential problems where "Postmaster" or 544838032Speter "POSTMASTER" might not match "postmaster". In most cases 544938032Speter this change is a no-op. 545038032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 545138032Speter Costales. 545238032Speter The -a map flag was ignored for dequote maps. Problem noted by 545338032Speter Bryan Costales. 545438032Speter Fix core dump when a lookup of a class "prog" map returns no 545538032Speter response. Patch from Bryan Costales. 545638032Speter Log instances where sendmail is deferring or rejecting connections 545738032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 545838032Speter Include port number in process title for network daemons. Suggested 545938032Speter by Kyle Jones of UUNET. 546038032Speter Send ``double bounces'' (errors that occur when sending an error 546138032Speter message) to the address indicated in the DoubleBounceAddress 546238032Speter option (default: postmaster). Previously they were always 546338032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 546438032Speter Add new mode, -bD, that acts like -bd in all respects except that 546538032Speter it runs in foreground. This is useful for using with a 546638032Speter wrapper that "watches" system services. Suggested by Kyle 546738032Speter Jones of UUNET. 546838032Speter Fix botch in spacing around (parenthesized) comments in addresses 546938032Speter when the comment comes before the address. Patch from 547038032Speter Motonori Nakamura of Kyoto University. 547138032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 547238032Speter that are being bounced to postmaster, rather than "Returned 547338032Speter mail". This permits the person who is postmaster more 547438032Speter easily determine what messages are to their role as 547538032Speter postmaster versus bounces to mail they actually sent. Based 547638032Speter on a suggestion by Motonori Nakamura. 547738032Speter Add new value "time" for QueueSortOrder option; this causes the queue 547838032Speter to be sorted strictly by the time of submission. Note that 547943730Speter this can cause very bad behavior over slow lines (because 548038032Speter large jobs will tend to delay small jobs) and on nodes with 548138032Speter heavy traffic (because old things in the queue for hosts that 548238032Speter are down delay processing of new jobs). Also, this does not 548338032Speter guarantee that jobs will be delivered in submission order 548438032Speter unless you also set DeliveryMode=queue. In general, it should 548538032Speter probably only be used on the command line, and only in 548638032Speter conjunction with -qRhost.domain. In fact, there are very few 548738032Speter cases where it should be used at all. Based on an 548838032Speter implementation by Motonori Nakamura. 548938032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 549038032Speter the same manner as other rulesets. Previously a temporary 549138032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 549238032Speter of Stanford University. 549338032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 549438032Speter 5yz (permanent failure) code. The next MX host will still be 549538032Speter tried if the connection cannot be opened in the first place 549638032Speter or if the MAIL command returns a 4yz (temporary failure) code. 549738032Speter (It's hard to know what to do here, since neither RFC 974 nor 549838032Speter RFC 1123 specify when to proceed to the next MX host.) 549938032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 550038032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 550138032Speter This causes map lookups that get a temporary failure (e.g., 550238032Speter name server failure) to _not_ defer the delivery of the 550338032Speter message. This should only be used if your configuration file 550438032Speter is prepared to do something sensible in this case. Based on 550538032Speter an idea by Gregory Shapiro of WPI. 550638032Speter Fix problem finding network interface addresses. Patch from 550738032Speter Motonori Nakamura. 550838032Speter Don't reject qf entries that are not owned by your effective uid if 550990792Sgshapiro you are not running set-user-ID; this makes management of 551080785Sgshapiro certain kinds of firewall setups difficult. Patch 551180785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 551238032Speter Add persistent host status. This keeps the information normally 551338032Speter maintained within a single queue run in disk files that are 551438032Speter shared between sendmail instances. The HostStatusDirectory 551538032Speter is the directory in which the information is maintained. If 551638032Speter not set, persistent host status is turned off. If not a full 551738032Speter pathname, it is relative to the queue directory. A common 551838032Speter value is ".hoststat". 551938032Speter There are also two new operation modes: 552038032Speter * -bh prints the status of hosts that have had recent 552138032Speter connections. 552238032Speter * -bH purges the host statuses. No attempt is made to save 552338032Speter recent status information. 552438032Speter This feature was originally written by Paul Vixie of Vixie 552538032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 552638032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 552738032Speter with my insistence that things fit cleanly into the V8 552838032Speter framework is gratefully appreciated. 552938032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 553038032Speter operate). Avoids letting two sendmails on the local machine 553164562Sgshapiro open connections to the same remote host at the same time. 553238032Speter This reduces load on the other machine, but can cause mail to 553338032Speter be delayed (for example, if one sendmail is delivering a huge 553438032Speter message, other sendmails won't be able to send even small 553538032Speter messages). Also, it requires another file descriptor (for the 553638032Speter lock file) per connection, so you may have to reduce 553738032Speter ConnectionCacheSize to avoid running out of per-process 553838032Speter file descriptors. Based on the persistent host status code 553938032Speter contributed by Paul Vixie and Mark Lovell. 554038032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 554138032Speter SafeFileEnvironment option is set. Problem noted by Bryan 554238032Speter Costales. 554338032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 554438032Speter file. Problem noted by Bryan Costales. 554538032Speter If a job was aborted using the interrupt signal (e.g., control-C from 554638032Speter the keyboard), on some occasions an empty df file would be 554738032Speter left around; these would collect in the queue directory. 554838032Speter Problem noted by Bryan Costales. 554938032Speter Change the makesendmail script to enhance the search for Makefiles 555038032Speter based on release number. For example, on SunOS 5.5.1, it will 555138032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 555238032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 555338032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 555438032Speter Webmasters. 555538032Speter When creating maps using "newaliases", always map the keys to lower 555638032Speter case when creating the map unless the -f flag is specified on 555738032Speter the map itself. Previously this was done based on the F=u 555838032Speter flag in the local mailer, which meant you could create aliases 555938032Speter that you could never access. Problem noted by Bob Wu of DEC. 556038032Speter When a job was read from the queue, the bits causing notification on 556138032Speter failure or delay were always set. This caused those 556238032Speter notifications to be sent even if NOTIFY=NEVER had been 556338032Speter specified. Problem noted by Steve Hubert of the University 556438032Speter of Washington, Seattle. 556538032Speter Add new configurable routine validate_connection (in conf.c). This 556638032Speter lets you decide if you are willing to accept traffic from 556738032Speter this host. If it returns FALSE, all SMTP commands will return 556838032Speter "550 Access denied". -DTCPWRAPPERS will include support for 556938032Speter TCP wrappers; you will need to add -lwrap to the link line. 557038032Speter (See src/READ_ME for details.) 557138032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 557238032Speter bounces. Some people seemed to think that this could be 557338032Speter confusing (even though it is true). Suggested by Motonori 557438032Speter Nakamura. 557538032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 557638032Speter user early in processing to avoid potential security problems. 557738032Speter However, this means that all .forward and :include: files must 557838032Speter be readable by that user, and all files to be written must be 557938032Speter writable by that user and all programs will be executed by that 558038032Speter user. It is also incompatible with the SafeFileEnvironment 558138032Speter option. In other words, it may not actually add much to 558238032Speter security. However, it should be useful on firewalls and other 558338032Speter places where users don't have accounts and the aliases file is 558438032Speter well constrained. 558538032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 558638032Speter only on the first attempt to delivery to an address. It could 558738032Speter be set to be lower than Timeout.connect on the principle that 558838032Speter the mail should go through quickly to responsive hosts; less 558938032Speter responsive hosts get to wait for the next queue run. 559038032Speter Fix a problem on Solaris that occasionally causes programs 559138032Speter (such as vacation) to hang with their standard input connected 559238032Speter to a UDP port. It also created some signal handling problems. 559338032Speter The problems turned out to be an interaction between vfork(2) 559438032Speter and some of the libraries, particularly NIS/NIS+. I am 559538032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 559638032Speter Change user class map to do the same matching that actual delivery 559738032Speter will do instead of just a /etc/passwd lookup. This adds 559838032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 559938032Speter The Timeout.* options are not safe -- they can be used to create a 560038032Speter denial-of-service attack. Problem noted by Christophe 560138032Speter Wolfhugel. 560243730Speter Don't send PostmasterCopy messages in the event of a "delayed" 560338032Speter notification. Suggested by Barry Bouwsma. 560438032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 560538032Speter option is set, since this disables VERB mode. Suggested 560638032Speter by John Hawkinson of MIT. 560738032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 560838032Speter by Motonori Nakamura of Kyoto University. 560938032Speter Only queue messages on transient .forward open failures if there 561043730Speter were no successful opens. The previous behavior caused it 561138032Speter to queue even if a "fall back" .forward was found. Problem 561238032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 561338032Speter and Computer Science (DISCS), NUS, Singapore. 561438032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 561538032Speter is bouncing because of a MIME error during 8->7 bit conversion; 561638032Speter the encapsulated message will bounce again, causing a loop. 561738032Speter Problem noted by Steve Hubert of the University of Washington. 561838032Speter Create xf (transcript) files using the TempFileMode option value 561938032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 562038032Speter National University of Singapore. 562138032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 562238032Speter detect cases where DefaultUid is set to something that the 562338032Speter system can't cope with. 562438032Speter PORTABILITY FIXES: 562538032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 562638032Speter Atlas International. 562738032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 562838032Speter <bicknell@ufp.org>. 562938032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 563038032Speter work on the first recipient of a message due to a 563138032Speter bug in the getpwent family.

Contributed by 567638032Speter Robert La Ferla of Hot Software. 567738032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 567838032Speter (where "code" is an exit status) on domains (previously 567938032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 568038032Speter Foundation. 568138032Speter CONFIG: hooks for IPv6-style domain literals. 568238032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 568338032Speter if it is undefined the AliasFile option is never set; this 568438032Speter should be transparent for most everyone. Suggested by John 568538032Speter Myers of CMU. 568638032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 568738032Speter domain listed in $=w is masqueraded. With it, only those 568838032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 568938032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 569038032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 569138032Speter hosts under those domains as well as the domain headers 569238032Speter themselves. For example, if a configuration had 569338032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 569438032Speter foo.com would be masqueraded; with it, *.foo.com would be 569538032Speter masqueraded as well. Based on an implementation by Richard 569638032Speter (Pug) Bainter of U.

Yes, 570038032Speter this does overlap with the user database, and figuring out 570138032Speter just when to use which one may be tricky. Based on code 570238032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 570338032Speter from Per Hedeland of Ericsson. 570438032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 570538032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 570638032Speter Keys are either fully qualified addresses or just the host 570738032Speter part (with the @ sign). For example, a table containing: 570838032Speter info@foo.com foo-info 570938032Speter info@bar.com bar-info 571038032Speter @baz.org jane@elsewhere.net 571138032Speter would send all mail destined for info@foo.com to foo-info 571238032Speter (which is presumably an alias), mail addressed to info@bar.com 571338032Speter to bar-info, and anything addressed to anyone at baz.org will 571438032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 571538032Speter and baz.org must all be in $=w. Based on discussions with 571638032Speter a great many people. 571738032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 571838032Speter Suggested by Richard Bainter. 571938032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 572038032Speter "fax" mailer. 572138032Speter CONFIG: allow mailertable entries to resolve to local:user; this 572238032Speter passes the original user@host in to procmail-style local 572338032Speter mailers as the "detail" information to allow them to do 572438032Speter additional clever processing. From Joe Pruett of 572538032Speter Teleport Corporation. Delivery to the original user can 572638032Speter be done by specifying "local:" (with nothing after the colon). 572738032Speter CONFIG: allow any context that takes "mailer:domain" to also take 572838032Speter "mailer:user@domain" to force mailing to the given user; 572938032Speter "local:user" can also be used to do local delivery. This 573038032Speter applies on *_RELAY and in the mailertable entries. Based 573138032Speter on a suggestion by Ribert Kiessling of Easynet. 573238032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 573338032Speter limits the possible domains; this reduces the number of DNS 573438032Speter lookups required to support this feature. For example, 573538032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 573638032Speter to domains under my.site.com. Code contributed by Anthony 573738032Speter Thyssen <anthony@cit.gu.edu.au>. 573838032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 573938032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 574038032Speter of WPI. 574138032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 574238032Speter event you have to define local mailers. Suggested by 574338032Speter Gregory Shapiro of WPI. 574438032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 574538032Speter be misinterpreted as a list:...; syntax. Based on a patch by 574638032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 574738032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 574838032Speter remotely connected. The address host!user was being 574938032Speter converted to host!user@thishost instead of host!user@uurelay. 575038032Speter Problem noted by William Gianopoulos of Raytheon Company. 575138032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 575238032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 575338032Speter "User has moved"; the former wording was confusing if the 575438032Speter new address is still on the local host. Based on a suggestion 575538032Speter by Andreas Luik. 575638032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 575738032Speter However, the class is not pre-initialized to contain root. 575838032Speter Suggested by Gregory Neil Shapiro. 575938032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 576038032Speter Wolfhugel. 576138032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 576238032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 576338032Speter well: this produces a slightly different mailbox format (no 576438032Speter Content-Length: headers), file ownerships and modes are 576538032Speter different (not owned by group mail; mode 600 instead of 660), 576638032Speter and the local mailer flags will have to be tweaked (make them 576738032Speter match bsd4.4) in order to use this mailer. Patches from Paul 576838032Speter Hammann of the Missouri Research and Education Network. 576938032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 577038032Speter was a delivery error, such as if the ownership on the file 577138032Speter was wrong or the mode changed between the initial stat and 577238032Speter the open. Problem reported by William Colburn of the New 577338032Speter Mexico Institute of Mining and Technology. 577438032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 577538032Speter Costales. 577638032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 577738032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 577838032Speter honored. Fix from Michael Scott Shappe. 577938032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 578038032Speter NEW FILES: 578138032Speter src/Makefiles/Makefile.AIX.2 578238032Speter src/Makefiles/Makefile.IRIX.6.2 578338032Speter src/Makefiles/Makefile.maxion 578438032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 578538032Speter src/Makefiles/Makefile.SCO.5.x 578638032Speter src/Makefiles/Makefile.UXPDSV20 578738032Speter mailstats/mailstats.8 578838032Speter praliases/praliases.8 578938032Speter cf/cf/generic-nextstep3.3.mc 579038032Speter cf/feature/genericstable.m4 579138032Speter cf/feature/limited_masquerade.m4 579238032Speter cf/feature/masquerade_entire_domain.m4 579338032Speter cf/feature/virtusertable.m4 579438032Speter cf/ostype/aix2.m4 579538032Speter cf/ostype/altos.m4 579638032Speter cf/ostype/maxion.m4 579738032Speter cf/ostype/solaris2.ml.m4 579838032Speter cf/ostype/uxpds.m4 579938032Speter contrib/re-mqueue.pl 580038032Speter DELETED FILES: 580138032Speter src/Makefiles/Makefile.Solaris 580238032Speter contrib/xla/README 580338032Speter contrib/xla/xla.c 580438032Speter RENAMED FILES: 580538032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 580638032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 580738032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 580838032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 580938032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 581038032Speter 581164562Sgshapiro8.7.6/8.7.3 1996/09/17 581238032Speter SECURITY: It is possible to force getpwuid to fail when writing the 581338032Speter queue file, causing sendmail to fall back to running programs 581438032Speter as the default user. This is not exploitable from off-site. 581538032Speter Workarounds include using a unique user for the DefaultUser 581638032Speter (old u & g options) and using smrsh as the local shell. 581738032Speter SECURITY: fix some buffer overruns; in at least one case this allows 581838032Speter a local user to get root. This is not known to be exploitable 581938032Speter from off-site. The workaround is to disable chfn(1) commands. 582038032Speter 582164562Sgshapiro8.7.5/8.7.3 1996/03/04 582238032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 582338032Speter in some case cause connections to hang or messages to have 582438032Speter extra spaces in odd places. Patch from Eric Wassenaar; 582538032Speter reports from Eric Hall of Chiron Corporation, Stephen 582638032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 582738032Speter and others. 582838032Speter 582964562Sgshapiro8.7.4/8.7.3 1996/02/18 583038032Speter SECURITY: In some cases it was still possible for an attacker to 583138032Speter insert newlines into a queue file, thus allowing access to 583238032Speter any user (except root). 583338032Speter CONFIG: no changes -- it is not a bug that the configuration 583438032Speter version number is unchanged. 583538032Speter 583664562Sgshapiro8.7.3/8.7.3 1995/12/03 583738032Speter Fix botch in name server timeout in RCPT code; this problem caused 583838032Speter two responses in SMTP, which breaks things horribly. Fix 583938032Speter from Gregory Neil Shapiro of WPI. 584038032Speter Verify that L= value on M lines cannot be negative, which could cause 584138032Speter negative array subscripting. Not a security problem since 584238032Speter this has to be in the config file, but it could have caused 584338032Speter core dumps. Pointed out by Bryan Costales. 584438032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 584538032Speter Costales. 584638032Speter PORTABILITY FIXES: 584738032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 584838032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 584938032Speter order. Tweak it to work properly. Based on fixes 585038032Speter from Fletcher Mattox of UTexas and Betty Lee of 585138032Speter Stanford University. 585238032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 585338032Speter Deficiency pointed out by Bryan Costales of ICSI. 585438032Speter 585564562Sgshapiro8.7.2/8.7.2 1995/11/19 585638032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 585738032Speter OperatorChars, and UnixFromLine options. They were not 585838032Speter properly repaired in 8.7.1. 585938032Speter Completely delete the Bcc: header if and only if there are other 586038032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 586138032Speter last being a historic botch, of course). If Bcc: is the 586238032Speter only recipient header in the message, its value is tossed, 586343730Speter but the header name is kept. The old behavior (always keep 586438032Speter the header name and toss the value) allowed primary recipients 586538032Speter to see that a Bcc: went to _someone_. 586638032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 586738032Speter sender to <address> using -f'' syslog messages. Suggested 586838032Speter by Kari Hurtta. 586938032Speter If a sequence or switch map lookup entry gets a tempfail but then 587038032Speter continues on to another map type, but the name is not found, 587138032Speter return a temporary failure from the sequence or switch map. 587238032Speter For example, if hosts search ``dns files'' and DNS fails 587338032Speter with a tempfail, the hosts map will go on and search files, 587438032Speter but if it fails the whole thing should be a tempfail, not 587538032Speter a permanent (host unknown) failure, even though that is the 587638032Speter failure in the hosts.files map. This error caused hard 587738032Speter bounces when it should have requeued. 587838032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 587990792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 588038032Speter working properly due to excessive paranoia. Pointed out by 588138032Speter John Hawkinson of Panix. 588238032Speter An SMTP RCPT command referencing a host that gave a nameserver 588338032Speter timeout would return a 451 command (8.6 accepted it and 588443730Speter queued it locally). Revert to the 8.6 behavior in order 588538032Speter to simplify queue management for clustered systems. Suggested 588638032Speter by Gregory Neil Shapiro of WPI. The same problem could break 588738032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 588838032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 588938032Speter Infobiogen. 589038032Speter Fix possible buffer overflow in munchstring(). This was not a security 589138032Speter problem because you couldn't specify any argument to this 589238032Speter without first giving up root privileges, but it is still a 589338032Speter good idea to avoid future problems. Problem noted by John 589438032Speter Hawkinson and Sam Hartman of MIT. 589538032Speter ``452 Out of disk space for temp file'' messages weren't being 589638032Speter printed. Fix from David Perlin of Nanosoft. 589743730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 589838032Speter is not set, since this is required to get the actual DSNs 589938032Speter created. Problem pointed out by John Gardiner Myers of CMU. 590038032Speter Log permission problems that cause .forward and :include: files to 590138032Speter be untrusted or ignored on log level 12 and higher. Suggested 590238032Speter by Randy Martin of Clemson University. 590338032Speter Allow user ids in U= clauses of M lines to have hyphens and 590438032Speter underscores. 590538032Speter Fix overcounting of recipients -- only happened when sending to an 590638032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 590738032Speter of Systems and Computer Technology Corporation. 590838032Speter If a message is sent to an address that fails, the error message that 590938032Speter is returned could show some extraneous "success" information 591038032Speter included even if the user did not request success notification, 591138032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 591238032Speter Config files that had no AliasFile definition were defaulting to 591338032Speter using /etc/aliases; this caused problems with nullclient 591438032Speter configurations. Change it back to the 8.6 semantics of 591538032Speter having no local alias file unless it is declared. Problem 591638032Speter noted by Charles Karney of Princeton University. 591738032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 591838032Speter Costales of ICSI. 591938032Speter Map lookups of class "userdb" maps were always case sensitive; they 592038032Speter should be controlled by the -f flag like other maps. Pointed 592138032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 592238032Speter Fix problem that caused some addresses to be passed through ruleset 5 592338032Speter even when they were tagged as "sticky" by prefixing the 592438032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 592538032Speter Technological University. 592638032Speter When converting a message to Quoted-Printable, prevent any lines with 592738032Speter dots alone on a line by themselves. This is because of the 592838032Speter preponderance of broken mailers that still get this wrong. 592938032Speter Code contributed by Per Hedeland of Ericsson. 593038032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 593138032Speter out by Bjart Kvarme of USIT/UiO (Norway). 593238032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 593338032Speter Requested by Allan Johannesen. 593438032Speter Delete check for text format of alias files -- it should be legal 593538032Speter to have the database format of the alias files without the 593638032Speter text version. Problem pointed out by Joe Rhett of Navigist, 593738032Speter Inc. 593838032Speter If "Ot" was specified with no value, the TZ variable was not properly 593938032Speter imported from the environment. Pointed out by Frank Crawford 594038032Speter <frank@ansto.gov.au>. 594138032Speter Some architectures core dumped on "program" maps that didn't have 594238032Speter extra arguments. Patch from Booker C. Bense of Stanford 594338032Speter University. 594438032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 594538032Speter the parent should do this. Fix from Brian Coan of the 594638032Speter Association for Progressive Communications. 594738032Speter If MinQueueAge was set and a message was considered but not run 594838032Speter during a queue run and the Timeout.queuereturn interval was 594938032Speter reached, a "timed out" error message would be returned that 595038032Speter didn't include the failed address (and claimed to be a warning 595138032Speter even though it was fatal). The fix is to not return such 595238032Speter messages until they are actually tried, i.e., in the next 595338032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 595438032Speter SINTEF RUNIT, Oslo. 595538032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 595638032Speter that have the hes_getmailhost() routine.

Bug 600338032Speter pointed out by John Hawkinson of MIT. 600438032Speter Fix strange case of an executable called by a program map that 600538032Speter returns a value but also a non-zero exit status; this 600638032Speter would give contradictory results in the higher level; in 600738032Speter particular, the default clause in the map lookup would be 600838032Speter ignored. Change to ignore the value if the program returns 600938032Speter non-zero exit status. From Tom Moore of AT&T GIS. 601038032Speter Shorten parameters passed to syslog() in some contexts to avoid a 601138032Speter bug in many vendors' implementations of that routine. Although 601238032Speter this isn't really a bug in sendmail per se, and my solution 601338032Speter has to assume that syslog() has at least a 1K buffer size 601438032Speter internally (I know some vendors have shortened this 601538032Speter dramatically -- they're on their own), sendmail is a popular 601638032Speter target. Also, limit the size of %s arguments in sprintf. 601738032Speter These both have possible security implications. Solutions 601838032Speter suggested by Casper Dik of Sun's Network Security Group 601938032Speter (Holland), Mark Seiden, and others. 602038032Speter Fix a problem that might cause a non-standard -B (body type) 602138032Speter parameter to be passed to the next server with undefined 602238032Speter results. This could have security implications. 602338032Speter If a filesystem was at > 100% utilization, the freediskspace() 602438032Speter routine incorrectly returned an error rather than zero. 602538032Speter Problem noted by G.

Fixes from Randy 603238032Speter Martin <WOLF@CLEMSON.EDU> 603338032Speter When sendmail starts up on systems that have no fully qualified 603438032Speter domain name (FQDN) anywhere in the first matching host map 603538032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 603638032Speter sendmail would sleep to try to find a FQDN, which it really 603738032Speter really needs. This has been changed to fall through to the 603838032Speter next map type if it can't find a FQDN -- i.e., if the hosts 603938032Speter file doesn't have a FQDN, it will try dns even though the 604038032Speter short name was found in /etc/hosts. This is probably a crock, 604138032Speter but many people have hosts files without FQDNs. Remember: 604238032Speter domain names are your friends. 604338032Speter Log a high-priority message if you can't find your FQDN during startup. 604438032Speter Suggested by Simon Barnes of Schlumberger Limited. 604538032Speter When using Hesiod, initialize it early to improve error reporting. 604638032Speter Patch from Don Lewis of Silicon Systems, Inc. 604738032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 604838032Speter connection timeout in the kernel. Add a new "connect" timeout 604938032Speter to limit this time. Defaults to zero (use whatever the 605038032Speter kernel provides). Based on code contributed by J.R. Oldroyd 605138032Speter of TerraNet. 605238032Speter Under some circumstances, a failed message would not be properly 605338032Speter removed from the queue, causing tons of bogus error messages. 605438032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 605538032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 605638032Speter of WPI. 605738032Speter PORTABILITY FIXES: 605838032Speter On IRIX 5.x, there was an inconsistency in the setting 605938032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 607538032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 607638032Speter otherwise the F=S causes the From_ line to imply that root is 607738032Speter the sender. Problem pointed out by Claude Scarpelli of 607838032Speter Infobiogen (France). 607938032Speter NEW FILES: 608038032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 608138032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 608238032Speter src/Makefiles/Makefile.UXPDS 608338032Speter 608464562Sgshapiro8.7/8.7 1995/09/16 608538032Speter Fix a problem that could cause sendmail to run out of file 608638032Speter descriptors due to a trashed data structure after a 608738032Speter vfork.

This was used "safely" in the sense 609338032Speter that it only did a stat, but it would have set the 609438032Speter map modification time improperly. Problem pointed out 609538032Speter by Roy Mongiovi of Georgia Tech. 609638032Speter Clean up the Subject: line on warning messages and return 609738032Speter receipts so that they don't say "Returned mail:"; this 609838032Speter can be confusing. 609938032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 610038032Speter useful enough to make it worthwhile printing on "-d". 610138032Speter Avoid logging alias statistics every time you read the alias 610238032Speter file on systems with no database method compiled in. 610338032Speter If you have a name with a trailing dot, and you try looking it 610438032Speter up using gethostbyname without the dot (for /etc/hosts 610538032Speter compatibility), be sure to turn off RES_DEFNAMES and 610638032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 610738032Speter Problem noted by Charles Amos of the University of 610838032Speter Maryland. 610938032Speter Don't do timeouts in collect if you are not running SMTP. 611038032Speter There is nothing that says you can't have a long 611138032Speter running program piped into sendmail (possibly via 611238032Speter /bin/mail, which just execs sendmail). Problem reported 611338032Speter by Don "Truck" Lewis of Silicon Systems. 611438032Speter Try gethostbyname() even if the DNS lookup fails iff option I 611538032Speter is not set. This allows you to have hosts listed in 611638032Speter NIS or /etc/hosts that are not known to DNS. It's normally 611738032Speter a bad idea, but can be useful on firewall machines. This 611838032Speter should really be broken out on a separate flag, I suppose. 611938032Speter Avoid compile warnings against BIND 4.9.3, which uses function 612038032Speter prototypes.

From Kyle Jones of UUNET. 612538032Speter SECURITY: avoid denial-of-service attacks possible by destroying 612638032Speter the alias database file by setting resource limits low. 612738032Speter This involves adding two new compile-time options: 612838032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 612938032Speter available) and HASULIMIT (indicating that ulimit(2) support 613038032Speter is available -- the Release 3 form is used). The former 613138032Speter is assumed on BSD-based systems, the latter on System 613238032Speter V-based systems. Attack noted by Phil Brandenberger of 613338032Speter Swarthmore University. 613438032Speter New syntaxes in test (-bt) mode: 613538032Speter ``.Dmvalue'' will define macro "m" to "value". 613638032Speter ``.Ccvalue'' will add "value" to class "c". 613738032Speter ``=Sruleset'' will dump the contents of the indicated 613838032Speter ruleset. 613938032Speter ``=M'' will display the known mailers. 614038032Speter ``-ddebug-spec'' is equivalent to the command-line 614138032Speter -d debug flag. 614238032Speter ``$m'' will print the value of macro $m. 614338032Speter ``$=c'' will print the contents of class $=c. 614438032Speter ``/mx host'' returns the MX records for ``host''. 614538032Speter ``/parse address'' will parse address, returning the value of 614638032Speter crackaddr (essentially, the comment information) 614738032Speter and the parsed address. 614838032Speter ``/try mailer address'' will rewrite address into the form 614938032Speter it will have when presented to the indicated mailer. 615038032Speter ``/tryflags flags'' will set flags used by parsing. The 615138032Speter flags can be `H' for header or `E' for envelope, 615238032Speter and `S' for sender or `R' for recipient. These 615338032Speter can be combined, so `HR' sets flags for header 615438032Speter recipients. 615538032Speter ``/canon hostname'' will try to canonify hostname and 615638032Speter return the result. 615738032Speter ``/map mapname key'' will look up `key' in the indicated 615838032Speter `mapname' and return the result. 615938032Speter Somewhat better handling of UNIX-domain socket addresses -- it 616038032Speter should show the pathname rather than hex bytes. 616138032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 616238032Speter the header for envelope sender information and uses 616338032Speter CR-LF as message terminators. It was thought to be 616438032Speter obsolete (used only for Arpanet NCP protocols), but it 616538032Speter turns out that the UK ``Grey Book'' protocols require 616638032Speter that functionality. 616738032Speter Fix a fix in previous release -- if gethostname and gethostbyname 616838032Speter return a name without dots, and if an attempt to canonify 616938032Speter that name fails, wait one minute and try again. This can 617038032Speter result in an extra 60 second delay on startup if your system 617138032Speter hostname (as returned by hostname(1)) has no dot and no names 617238032Speter listed in /etc/hosts or your NIS map have a dot. 617338032Speter Check for proper domain name on HELO and EHLO commands per 617438032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 617538032Speter of Michigan Technological University. 617638032Speter Relax chownsafe rules slightly -- old version said that if you 617738032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 617838032Speter if fpathconf returned EINVAL or ENOSYS), assume that 617938032Speter chown is not safe. The new version falls back to whether 618038032Speter you are on a BSD system or not. This is important for 618138032Speter SunOS, which apparently always returns one of those 618238032Speter error codes. This impacts whether you can mail to files 618338032Speter or not. 618438032Speter Syntax errors such as unbalanced parentheses in the configuration 618538032Speter file could be omitted if you had "Oem" prior to the 618638032Speter syntax error in the config file. Change to always print 618738032Speter the error message. It was especially weird because it 618838032Speter would cause a "warning" message to be sent to the Postmaster 618938032Speter for every message sent (but with no transcript). Problem 619038032Speter noted by Gregory Paris of Motorola. 619138032Speter Rewrite collect and putbody to handle full 8-bit data, including 619238032Speter zero bytes.

This is to handle the 626138032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 626238032Speter assume that ``group name:'' is a comment on the first 626338032Speter address and the ``;'' is a comment on the last address). 626438032Speter This requires config file support to get right. It does 626538032Speter understand that :: is NOT this syntax, and can be turned 626638032Speter off completely by setting the ColonOkInAddresses option. 626738032Speter Level 6 config files added with new mailer flags: 626838032Speter A Addresses are aliasable. 626938032Speter i Do udb rewriting on envelope as well as header 627038032Speter sender lines. Applies to the from address mailer 627138032Speter flags rather than the recipient mailer flags. 627238032Speter j Do udb rewriting on header recipient addresses. 627338032Speter Applies to the sender mailer flags rather than the 627438032Speter recipient mailer flags. 627538032Speter k Disable check for loops when doing HELO command. 627638032Speter o Always run as the mail recipient, even on local 627738032Speter delivery. 627838032Speter w Check for an /etc/passwd entry for this user. 627938032Speter 5 Pass addresses through ruleset 5. 628038032Speter : Check for :include: on this address. 628138032Speter | Check for |program on this address. 628238032Speter / Check for /file on this address. 628338032Speter @ Look up sender header addresses in the user 628438032Speter database. Applies to the mailer flags for the 628538032Speter mailer corresponding to the envelope sender 628638032Speter address, rather than to recipient mailer flags. 628738032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 628838032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 628938032Speter mailers, and the ColonOkInAddresses option. 629038032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 629138032Speter John Beck of Hewlett-Packard, who generously contributed 629238032Speter their implementation to me, which I then didn't use (see 629338032Speter mime.c for an explanation of why). This adds the 629438032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 629538032Speter to control handling of 8-bit data. These have to cope with 629638032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 629738032Speter 8-bit data that is entered without declaring it as 8-bit 629838032Speter MIME -- technically this is illegal according to the 629938032Speter specs) and labelled 8-bit data (that is, it was declared 630038032Speter as 8BITMIME in the ESMTP session or by using the 630138032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 630238032Speter set then 8-bit data is sent to non-8BITMIME machines 630338032Speter instead of converting to 7 bit (essentially using 630438032Speter just-send-8 semantics). The values for EightBitMode are: 630538032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 630638032Speter any necessary conversion of 8BITMIME to 7BIT 630738032Speter (essentially, the full MIME option). 630838032Speter p pass unlabelled 8-bit input, but convert labelled 630938032Speter 8BITMIME input to 7BIT as required (default). 631038032Speter s strict adherence: reject unlabelled 8-bit input, 631138032Speter convert 8BITMIME to 7BIT as required. The F=8 631238032Speter flag is ignored. 631338032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 631438032Speter the setting of F=8. 631538032Speter Add new internal class 'n', which is the set of MIME Content-Types 631638032Speter which can not be 8 to 7 bit encoded because of other 631738032Speter considerations. Types "multipart/*" and "message/*" are 631838032Speter never directly encoded (although their components can be). 631938032Speter Add new internal class 's', which is the set of subtypes of the 632038032Speter MIME message/* content type that can be treated as though 632138032Speter they are an RFC822 message. It is predefined to have 632238032Speter "rfc822". Suggested By Kari Hurtta. 632338032Speter Add new internal class 'e'. This is the set of MIME 632438032Speter Content-Transfer-Encodings that can be converted to 632538032Speter a seven bit format (Quoted-Printable or Base64). It is 632638032Speter preinitialized to contain "7bit", "8bit", and "binary". 632738032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 632838032Speter short name) to set the default character set to use in the 632938032Speter Content-Type: header when doing encoding of an 8-bit message 633038032Speter which isn't marked as MIME into MIME format. If the C= 633138032Speter parameter is set on the Envelope From address, use that as 633238032Speter the default encoding; else use the DefaultCharSet option. 633338032Speter If neither is set, it defaults to "unknown-8bit" as 633438032Speter suggested by RFC 1428 section 3. 633538032Speter Allow ``U=user:group'' field in mailer definition to set a default 633638032Speter user and group that a mailer will be executed as. This 633738032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 633838032Speter also set, it is the uid/gid that will always be used (that 633938032Speter is, the controlling address is ignored). The values may be 634038032Speter numeric or symbolic; if only a symbolic user is given (no 634138032Speter group) that user's default group in the passwd file is used 634238032Speter as the group. Based on code donated by Chip Rosenthal of 634338032Speter Unicom. 634438032Speter Allow `u' option to also accept user:group as a value, in the same 634538032Speter fashion as the U= mailer option. 634638032Speter Add the symbolic time zone name in the Arpanet format dates (as 634738032Speter a comment). This adds a new compile-time configuration 634838032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 634938032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 635038032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 635138032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 635238032Speter timezone()), or TZ_NONE (don't include the comment). Code 635338032Speter from Chip Rosenthal. 635438032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 635538032Speter For example, 635638032Speter O Timeout.helo = 2m 635738032Speter There are also two new suboptions "queuereturn" and 635838032Speter "queuewarn"; these subsume the old T option. Thus, to 635938032Speter set them both the preferred new syntax is 636038032Speter O Timeout.queuereturn = 5d 636138032Speter O Timeout.queuewarn = 4h 636238032Speter Sort queue by host name instead of by message priority if the 636338032Speter QueueSortOrder option (no short name) is set is set to 636438032Speter ``host''. This makes better use of the connection cache, 636538032Speter but may delay more ``interactive'' messages behind large 636638032Speter backlogs under some circumstances. This is probably a 636738032Speter good option if you have high speed links or don't do lots 636838032Speter of ``batch'' messages, but less good if you are using 636938032Speter something like PPP on a 14.4 modem. Based on code 637038032Speter contributed by Roy Mongiovi of Georgia Tech (my main 637138032Speter contribution was to make it configurable). 637238032Speter Save i-number of df file in qf file to simplify rebuilding of queue 637338032Speter after disastrous disk crash. Suggested by Kyle Jones of 637438032Speter UUNET; closely based on code from KJS DECWRL code written 637538032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 637638032Speter are NOT back compatible with 8.6 -- that is, you can convert 637738032Speter from 8.6 to 8.7, but not the other direction. 637838032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 637938032Speter route-addrs in envelopes; this is because in some cases 638038032Speter they can be sent to the shell, which interprets them as 638138032Speter I/O redirection. 638238032Speter Don't include error file (option E) with return-receipts; this 638338032Speter can be confusing. 638438032Speter Don't send "Warning: cannot send" messages to owner-* or 638538032Speter *-request addresses. Suggested by Christophe Wolfhugel 638638032Speter of the Institut Pasteur, Paris. 638738032Speter Allow -O command line flag to set long form options. 638838032Speter Add "MinQueueAge" option to set the minimum time between attempts 638938032Speter to run the queue. For example, if the queue interval 639038032Speter (-q value) is five minutes, but the minimum queue age 639138032Speter is fifteen minutes, jobs won't be tried more often than 639238032Speter once every fifteen minutes. This can be used to give 639338032Speter you more responsiveness if your delivery mode is set to 639438032Speter queue-only. 639538032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 639638032Speter :include: and .forward files. 639738032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 639838032Speter key field name, the value field name, and the field 639938032Speter delimiter. The field delimiter can be a single character 640038032Speter or the sequence "\t" or "\n" for tab or newline. 640138032Speter These are for use by NIS+ and similar access methods. 640238032Speter Change maps to always strip quotes before lookups; the -q flag 640343730Speter turns off this behavior. Suggested by Motonori Nakamura. 640438032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 640538032Speter key and value field names respectively. Code donated by 640638032Speter Sun Microsystems. 640738032Speter Add "hesiod" map class. The "file name" is used as the 640838032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 640938032Speter first value found for the match. Code donated by Scott 641038032Speter Hutton of Indiana University. 641138032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 641238032Speter specify the name of the property that is searched as the 641338032Speter key and a -v flag to specify the name of the property that 641438032Speter is returned as the value (defaults to "members"). The 641538032Speter default map is "/aliases". Some code based on code 641638032Speter contributed by Robert La Ferla of Hot Software. 641738032Speter Add "text" map class. This does slow, linear searches through 641838032Speter text files. The -z flag specifies a column delimiter 641938032Speter (defaults to any sequence of white space), the -k flag 642038032Speter sets the key column number, and the -v flag sets the 642138032Speter value column number. Lines beginning with `#' are treated 642238032Speter as comments. 642338032Speter Add "program" map class to execute arbitrary programs. The search 642438032Speter key is presented as the last argument; the output is one 642538032Speter line read from the programs standard output. Exit statuses 642638032Speter are from sysexits.h. 642738032Speter Add "sequence" map class -- searches maps in sequence until it 642838032Speter finds a match. For example, the declarations: 642938032Speter Kmap1 ... 643038032Speter Kmap2 ... 643138032Speter Kmapseq sequence map1 map2 643238032Speter defines a map "mapseq" that first searches map1; if the 643338032Speter value is found it is returned immediately, otherwise 643438032Speter map2 is searched and the value returned. 643538032Speter Add "switch" map class. This is much like "sequence" except that 643638032Speter the ordering is fetched from an external file, usually 643738032Speter the system service switch. The parameter is the name of 643838032Speter the service to switch on, and the maps that it will use 643938032Speter are the name of the switch map followed by ".service_type". 644038032Speter For example, if the declaration of the map is 644138032Speter Ksample switch hosts 644238032Speter and the system service switch specifies that hosts are 644338032Speter looked up using dns and nis in that order, then this is 644438032Speter equivalent to 644538032Speter Ksample sequence sample.dns sample.nis 644638032Speter The subordinate maps (sample.*) must already be defined. 644738032Speter Add "user" map class -- looks up users using getpwnam. Takes a 644838032Speter "-v field" flag on the definition that tells what passwd 644938032Speter entry to return -- legal values are name, passwd, uid, gid, 645038032Speter gecos, dir, and shell. Generally expected to be used with 645138032Speter the -m (matchonly) flag. 645238032Speter Add "bestmx" map class -- returns the best MX value for the host 645338032Speter listed as the value. If there are several "best" MX records 645438032Speter for this host, one will be chosen at random. 645538032Speter Add "userdb" map class -- looks up entries in the user database. 645638032Speter The "file name" is actually the tag that will be used, 645738032Speter typically "mailname". If there are multiple entries 645838032Speter matching the name, the one chosen is undefined. 645938032Speter Add multiple queue timeouts (both return and warning). These are 646038032Speter set by the Precedence: or Priority: header fields to one of 646138032Speter three values. If a Priority: is set and has value "normal", 646264562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 646338032Speter used. If no priority is set, the Precedence: is consulted; 646438032Speter if negative, non-urgent timeouts are used; if greater than 646538032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 646638032Speter are used. The timeouts are set by setting the six timeouts 646738032Speter queue{warn,return}.{urgent,normal,non-urgent}. 646838032Speter Fix problem when a mail address is resolved to a $#error mailer 646938032Speter with a temporary failure indication; it works in SMTP, 647038032Speter but when delivering locally the mail is silently discarded. 647138032Speter This patch, from Kyle Jones of UUNET, bounces it instead 647238032Speter of queueing it (queueing is very hard). 647338032Speter When using /etc/hosts or NIS-style lookups, don't assume that 647438032Speter the first name in the list is the best one -- instead, 647538032Speter search for the first one with a dot. For example, if 647638032Speter an /etc/hosts entry reads 647738032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 647838032Speter this change will use the second name as the canonical 647938032Speter machine name instead of the initial, unqualified name. 648038032Speter Change dequote map to replace spaces in quoted text with a value 648138032Speter indicated by the -s flag on the dequote map definition. 648238032Speter For example, ``Mdequote dequote -s_'' will change 648338032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 648438032Speter quoted (because of the space character). Suggested by Dan 648538032Speter Oscarsson for use in X.400 addresses. 648638032Speter Implement long macro names as ${name}; long class names can 648738032Speter be similarly referenced as $={name} and $~{name}. 648838032Speter Definitions are (e.g.) ``D{name}value''. Names that have 648938032Speter a leading lower case letter or punctuation characters are 649038032Speter reserved for internal use by sendmail; i.e., config files 649138032Speter should use names that begin with a capital letter. Based 649238032Speter on code contributed by Dan Oscarsson. 649338032Speter Fix core dump if getgrgid returns a null group list (as opposed 649438032Speter to an empty group list, that is, a pointer to a list 649538032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 649638032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 649738032Speter failed, it called syserr which called newstr which called 649838032Speter xalloc.... The newstr is now avoided for "panic" messages. 649938032Speter Reported by Stuart Kemp of James Cook University. 650038032Speter Improve connection cache timeouts; previously, they were not even 650138032Speter checked if you were delivering to anything other than an 650238032Speter IPC-connected host, so a series of (say) local mail 650338032Speter deliveries could cause cached connections to be open 650438032Speter much longer than the specified timeout. 650538032Speter If an incoming message exceeds the maximum message size, stop 650638032Speter writing the incoming bytes to the queue data file, since 650738032Speter this can fill your mqueue partition -- this is a possible 650838032Speter denial-of-service attack. 650938032Speter Don't reject all numeric local user names unless HESIOD is 651038032Speter defined. It turns out that Posix allows all-numeric 651138032Speter user names. Fix from Tony Sanders of BSDI. 651238032Speter Add service switch support. If the local OS has a service 651338032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 651438032Speter on DEC systems) that will be used; otherwise, it falls back 651538032Speter to using a local mechanism based on the ServiceSwitchFile 651638032Speter option (default: /etc/service.switch). For example, if the 651738032Speter service switch lists "files" and "nis" for the aliases 651838032Speter service, that will be the default lookup order. the "files" 651938032Speter ("local" on DEC) service type expands to any alias files 652038032Speter you listed in the configuration file, even if they aren't 652138032Speter actually file lookups. 652238032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 652338032Speter variable which tells whether or not DNS should be considered 652438032Speter canonical. This is now determined based on whether or not 652538032Speter "dns" is in the service list for "hosts". 652638032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 652738032Speter Status Notifications). DSN notifications override 652838032Speter Return-Receipt-To: headers, which are bogus anyhow -- 652938032Speter support for them has been removed. 653038032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 653138032Speter definitions to define the types used in DSN returns for 653238032Speter MTA names, addresses, and diagnostics respectively. 653338032Speter Extend heuristic to force running in ESMTP mode to look for the 653438032Speter five-character string "ESMTP" anywhere in the 220 greeting 653538032Speter message (not just the second line). This is to provide 653638032Speter better compatibility with other ESMTP servers. 653738032Speter Print sequence number of job when running the queue so you can 653838032Speter easily see how much progress you have made. Suggested 653938032Speter by Peter Wemm of DIALix. 654038032Speter Map newlines to spaces in logged message-ids; some versions of 654138032Speter syslog truncate the rest of the line after newlines. 654238032Speter Suggested by Fletcher Mattox of U. Texas. 654338032Speter Move up forking for job runs so that if a message is split into 654438032Speter multiple envelopes you don't get "fork storms" -- this 654538032Speter also improves the connection cache utilization. 654638032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 654738032Speter the purposes of refusing to send error returns. Suggested 654838032Speter by Motonori Nakamura of Ritsumeikan University. 654938032Speter Relax rules on when a file can be written when referenced from 655038032Speter the aliases file: use the default uid/gid instead of the 655138032Speter real uid/gid. This allows you to create a file owned by 655238032Speter and writable only by the default uid/gid that will work 655390792Sgshapiro all the time (without having the set-user-ID bit set). Change 655438032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 655538032Speter Microsystems. 655638032Speter Add "DialDelay" option (no short name) to provide an "extra" 655738032Speter delay for dial on demand systems. If this is non-zero 655838032Speter and a connect fails, sendmail will wait this long and 655938032Speter then try again. If it takes longer than the kernel 656038032Speter timeout interval to establish the connection, this 656138032Speter option can give the network software time to establish 656238032Speter the link. The default units are seconds. 656338032Speter Move logging of sender information to be as early as possible; 656438032Speter previously, it could be delayed a while for SMTP mail 656538032Speter sent to aliases. Suggested by Brad Knowles of the 656638032Speter Defense Information Systems Agency. 656738032Speter Call res_init() before setting RES_DEBUG; this is required by 656838032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 656938032Speter the National Computer Security Center. 657038032Speter Add xdelay= field in logs -- this is a transaction delay, telling 657138032Speter you how long it took to deliver to this address on the 657238032Speter last try. It is intended to be used for sorting mailing 657338032Speter lists to favor "quick" addresses. Provided for use by 657438032Speter the mailprio scripts (see below). 657538032Speter If a map cannot be opened, and that map is non-optional, and 657638032Speter an address requires that map for resolution, queue the 657738032Speter map instead of bouncing it. This involves creating a 657838032Speter pseudo-class of maps called "bogus-map" -- if a required 657938032Speter map cannot be opened, the class is changed to bogus-map; 658038032Speter all queries against bogus-map return "tempfail". The 658138032Speter bogus-map class is not directly accessible. A sample 658238032Speter implementation was donated by Jem Taylor of Glasgow 658338032Speter University Computing Service. 658438032Speter Fix a possible core dump when mailing to a program that talks 658538032Speter SMTP on its standard input. Fix from Keith Moore of 658638032Speter the University of Kentucky. 658738032Speter Make it possible to resolve filenames to $#local $: @ /filename; 658838032Speter previously, the "@" would cause it to not be recognized 658938032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 659038032Speter Accept a -1 signal to re-exec the daemon. This only works if 659138032Speter argv[0] is a full path to sendmail. 659238032Speter Fix bug in "addr=..." field in O option on little-endian machines 659338032Speter -- the network number wasn't being converted to network 659438032Speter byte order. Patch from Kurt Lidl of Pix Technologies 659538032Speter Corporation. 659638032Speter Pre-initialize the resolver early on; this is to avoid a bug with 659738032Speter BIND 4.9.3 that can cause the _res.retry field to get 659838032Speter reset to zero, causing all name server lookups to time 659938032Speter out. Fix from Matt Day of Artisoft. 660038032Speter Restore T line (trusted users) in config file -- but instead of 660138032Speter locking out the -f flag, they just tell whether or not 660238032Speter an X-Authentication-Warning: will be added. This really 660338032Speter just creates new entries in class 't', so "Ft/file/name" 660438032Speter can be used to read trusted user names from a file. 660538032Speter Trusted users are also allowed to execute programs even 660638032Speter if they have a shell that isn't in /etc/shells. 660738032Speter Improve NEWDB alias file rebuilding so it will create them 660838032Speter properly if they do not already exist. This had been 660938032Speter a MAYBENEXTRELEASE feature in 8.6.9. 661038032Speter Check for @:@ entry in NIS maps before starting up to avoid 661138032Speter (but not prevent, sigh) race conditions. This ought to 661238032Speter be handled properly in ypserv, but isn't. Suggested by 661338032Speter Michael Beirne of Motorola. 661438032Speter Refuse connections if there isn't enough space on the filesystem 661538032Speter holding the queue. Contributed by Robert Dana of Wolf 661638032Speter Communications. 661738032Speter Skip checking for directory permissions in the path to a file 661838032Speter when checking for file permissions iff setreuid() 661938032Speter succeeded -- it is unnecessary in that case. This avoids 662038032Speter significant performance problems when looking for .forward 662138032Speter files. Based on a suggestion by Win Bent of USC. 662238032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 662338032Speter arbitrary ruleset number assigned or "Sname = integer" 662438032Speter to assign a specific ruleset number. Reference is 662538032Speter $>name_or_number. Names can be composed of alphas, digits, 662638032Speter underscore, or hyphen (first character must be non-numeric). 662738032Speter Allow -o flag on AliasFile lines to make the alias file optional. 662838032Speter From Bryan Costales of ICSI. 662938032Speter Add NoRecipientAction option to handle the case where there is 663038032Speter no legal recipient header in the message. It can take 663138032Speter on values: 663238032Speter None Leave the message as is. The 663338032Speter message will be passed on even 663438032Speter though it is in technically 663538032Speter illegal syntax. 663638032Speter Add-To Add a To: header with any 663738032Speter recipients that it can find from 663838032Speter the envelope. This risks exposing 663938032Speter Bcc: recipients. 664038032Speter Add-Apparently-To Add an Apparently-To: header. This 664138032Speter has almost no redeeming social value, 664238032Speter and is provided only for back 664338032Speter compatibility. 664438032Speter Add-To-Undisclosed Add a header reading 664538032Speter To: undisclosed-recipients:; 664638032Speter which will have the effect of 664738032Speter making the message legal without 664838032Speter exposing Bcc: recipients. 664938032Speter Add-Bcc To add an empty Bcc: header. 665038032Speter There is a chance that mailers down 665138032Speter the line will delete this header, 665238032Speter which could cause exposure of Bcc: 665338032Speter recipients. 665438032Speter The default is NoRecipientAction=None. 665538032Speter Truncate (rather than delete) Bcc: lines in the header. This 665638032Speter should prevent later sendmails (at least, those that don't 665738032Speter themselves delete Bcc:) from considering this message to 665838032Speter be non-conforming -- although it does imply that non-blind 665938032Speter recipients can see that a Bcc: was sent, albeit not to whom. 666038032Speter Add SafeFileEnvironment option. If declared, files named as delivery 666138032Speter targets must be regular files in addition to the regular 666238032Speter checks. Also, if the option is non-null then it is used as 666338032Speter the name of a directory that is used as a chroot(2) 666438032Speter environment for the delivery; the file names listed in an 666538032Speter alias or forward should include the name of this root. 666638032Speter For example, if you run with 666738032Speter O SafeFileEnvironment=/arch 666838032Speter then aliases should reference "/arch/rest/of/path". If a 666938032Speter value is given, sendmail also won't try to save to 667038032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 667138032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 667238032Speter Support -A flag for alias files; this will comma concatenate like 667338032Speter entries. For example, given the aliases: 667438032Speter list: member1 667538032Speter list: member2 667638032Speter and an alias file declared as: 667738032Speter OAhash:-A /etc/aliases 667838032Speter the final alias inserted will be "list: member1,member2"; 667938032Speter without -A you will get an error on the second and subsequent 668038032Speter alias for "list". Contributed by Bryan Costales of ICSI. 668138032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 668238032Speter Fix a problem that could cause very long addresses to core dump in 668338032Speter some special circumstances. Problem pointed out by Allan 668438032Speter Johannesen. 668538032Speter (Internal change.) Change interface to expand() (macro expansion) 668638032Speter to be simpler and more consistent. 668738032Speter Delete check for funny qf file names. This didn't really give 668838032Speter any extra security and caused some people some problems. 668938032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 669038032Speter at compile time.) Suggested by Kyle Jones of UUNET. 669138032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 669238032Speter merge with DSN code; this is simpler and more consistent. 669338032Speter This may affect some people who have written their own 669438032Speter checkcompat() routine. 669538032Speter (Internal change.) Eliminate `D' line in qf file. The df file 669638032Speter is now assumed to be the same name as the qf file (with 669738032Speter the `q' changed to a `d', of course). 669838032Speter Avoid forking for delivery if all recipient mailers are marked as 669938032Speter "expensive" -- this can be a major cost on some systems. 670038032Speter Essentially, this forces sendmail into "queue only" mode 670138032Speter if all it is going to do is queue anyway. 670238032Speter Avoid sending a null message in some rather unusual circumstances 670338032Speter (specifically, the RCPT command returns a temporary 670438032Speter failure but the connection is lost before the DATA 670538032Speter command). Fix from Scott Hammond of Secure Computing 670638032Speter Corporation. 670738032Speter Change makesendmail to use a somewhat more rational naming scheme: 670838032Speter Makefiles and obj directories are named $os.$rel.$arch, 670938032Speter where $os is the operating system (e.g., SunOS), $rel is 671038032Speter the release number (e.g., 5.3), and $arch is the machine 671138032Speter architecture (e.g., sun4). Any of these can be omitted, 671238032Speter and anything after the first dot in a release number can 671338032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 671438032Speter version used $os.$arch.$rel and was rather less general. 671538032Speter Change makesendmail to do a "make depend" in the target directory 671638032Speter when it is being created. This involves adding an empty 671738032Speter "depend:" entry in most Makefiles. 671838032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 671938032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 672038032Speter of the Finnish Meteorological Institute. 672138032Speter Fix problem that could cause multiple responses to DATA command 672238032Speter on header syntax errors (e.g., lines beginning with colons). 672338032Speter Problem noted by Jens Thomassen of the University of Oslo. 672438032Speter Don't let null bytes in headers cause truncation of the rest of 672538032Speter the header. 672638032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 672738032Speter Increase timeouts on message data puts to allow time for receivers 672838032Speter to canonify addresses in headers on the fly. This is still 672938032Speter a rather ugly heuristic. From Motonori Nakamura. 673038032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 673138032Speter records are not used when canonifying names, and when MX 673238032Speter lookups are done for addressing they must be fully 673338032Speter qualified. This is useful if you have a wildcard MX record, 673438032Speter although it may cause other problems. In general, don't use 673538032Speter wildcard MX records. Patch from Motonori Nakamura. 673638032Speter Eliminate default two-line SMTP greeting message. Instead of 673738032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 673838032Speter is added between the first and second word of the first 673938032Speter line of the greeting message (i.e., immediately after the 674038032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 674138032Speter compile flag. Old sendmails won't see the ESMTP, but that's 674238032Speter acceptable because SIZE was the only useful extension that 674338032Speter old sendmails understand. 674438032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 674538032Speter invoked state dumps. From Masaharu Onishi. 674638032Speter Allow on-line comments in .forward and :include: files; they are 674738032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 674838032Speter is a space or a tab. This is intended for native 674938032Speter representation of non-ASCII sets such as Japanese, where 675038032Speter existing encodings would be unreadable or would lose 675138032Speter data -- for example, 675238032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 675338032Speter (romanized/less information) 675438032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 675538032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 675638032Speter (with MIME encoding, not human readable) 675738032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 675838032Speter (native encoding with ISO-2022-JP) 675938032Speter The last form is human readable in the Japanese environment. 676038032Speter Based on a fix from (surprise!) Motonori Nakamura. 676138032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 676238032Speter messages to that host; these are most frequently associated 676338032Speter with addresses rather than the host, with the exception of 676438032Speter 421 (service shutting down). The effect was to cause queues 676538032Speter to sometimes take an excessive time to flush. Reported by 676638032Speter Robert Sargent of Southern Geographics Technologies and 676738032Speter Eric Prestemon of American University. 676838032Speter Add Nice=N mailer option to set the niceness at which a mailer will 676938032Speter run. This is actually a relative niceness (that is, an 677038032Speter increment on the background value). 677138032Speter Log queue runs that are skipped due to high loads. They are logged 677238032Speter at LOG_INFO priority iff the log level is > 8. Contributed 677338032Speter by Bruce Nagel of Data General. 677438032Speter Allow the error mailer to accept a DSN-style error status code 677538032Speter instead of an sysexits status code in the host part. 677638032Speter Anything with a dot will be interpreted as a DSN-style code. 677738032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 677838032Speter to encode characters that might be munged by an EBCDIC system 677938032Speter in addition to the set required by RFC 1521. The additional 678038032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 678138032Speter (Think of "IBM 360" as the mnemonic for this flag.) 678238032Speter Change check for mailing to files to look for a pathname of [FILE] 678338032Speter rather than looking for the mailer named *file*. The mapping 678438032Speter of leading slashes still goes to the *file* mailer. This 678538032Speter allows you to implement the *file* mailer as a separate 678638032Speter program, for example, to insert a Content-Length: header 678738032Speter or do special security policy. However, note that the usual 678838032Speter initial checking for the file permissions is still done, and 678938032Speter the program in question needs to be very careful about how 679038032Speter it does the file write to avoid security problems. 679138032Speter Be able to read ~root/.forward even if the path isn't accessible to 679238032Speter regular users. This is disrecommended because sendmail 679338032Speter sometimes does not run as root (e.g., when an unsafe option 679438032Speter is specified on the command line), but should otherwise be 679538032Speter safe because .forward files must be owned by the user for 679638032Speter whom mail is being forwarded, and cannot be a symbolic link. 679738032Speter Suggested by Forrest Aldrich of Wang Laboratories. 679838032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 679938032Speter file. This is used for canonifying hostnames when the 680038032Speter service type is "files". 680138032Speter Implement programs on F (read class from file) line. The syntax is 680238032Speter Fc|/path/to/program to read the output from the program 680338032Speter into class "c". 680438032Speter Probe the network interfaces to find alternate names for this 680538032Speter host. Requires the SIOCGIFCONF ioctl call. Code 680638032Speter contributed by SunSoft. 680738032Speter Add "E" configuration line to set or propagate environment 680838032Speter variables into children. "E<envar>" will propagate 680938032Speter the named variable from the environment when sendmail 681038032Speter was invoked into any children it calls; "E<envar>=<value>" 681138032Speter sets the named variable to the indicated value. Any 681238032Speter variables not explicitly named will not be in the child 681338032Speter environment. However, sendmail still forces an 681438032Speter "AGENT=sendmail" environment variable, in part to enforce 681538032Speter at least one environment variable, since many programs and 681638032Speter libraries die horribly if this is not guaranteed. 681738032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 681838032Speter alias databases -- new algorithm looks for the substring 681938032Speter "/yp/" in the file name. This is more portable and involves 682038032Speter less overhead. Suggested by Motonori Nakamura. 682138032Speter Dynamically allocate the queue work list so that you don't lose 682238032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 682338032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 682438032Speter should not need to be changed) and the MaxQueueRunSize option, 682538032Speter which is the absolute maximum number of jobs that will ever 682638032Speter be handled in a single queue run. Based on code contributed 682738032Speter by Brian Coan of the Institute for Global Communications. 682838032Speter Log message when a message is dropped because it exceeds the maximum 682938032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 683038032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 683138032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 683238032Speter of Mark G. Thomas Consulting. 683338032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 683438032Speter OS-dependent defines). The old semantic of -d0.1 to not 683538032Speter run the daemon in background has been moved to -d99.100, 683638032Speter and the old 52.5 flag (to avoid disconnect() from closing 683738032Speter all output files) has been moved to 52.100. This makes 683838032Speter things more consistent (flags below .100 don't change 683938032Speter semantics) and separates out the backgrounding so that 684038032Speter it doesn't happen automatically on other unrelated debugging 684138032Speter flags. 684238032Speter If -t is used but no addresses are found in the header, give an 684338032Speter error message rather than just doing nothing. Fix from 684438032Speter Motonori Nakamura. 684538032Speter On systems (like SunOS) where the effective gid is not necessarily 684638032Speter included in the group list returned by getgroups(), the 684738032Speter `restrictmailq' option could sometimes cause an authorized 684838032Speter user to not be able to use `mailq'. Fix from Charles Hannum 684938032Speter of MIT. 685038032Speter Allow symbolic service names for [IPC] mailers. Suggested by 685138032Speter Gerry Magennis of Logica International. 685238032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 685338032Speter when running DNS. For example, if the name FTP.Foo.ORG is 685438032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 685538032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 685638032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 685738032Speter This is technically illegal under RFC 822 and 1123, but the 685838032Speter IETF is moving toward legalizing it. Note that turning on 685938032Speter this option is not sufficient to guarantee that a downstream 686038032Speter neighbor won't rewrite the address for you. 686138032Speter Add "-m" flag to makesendmail script -- this tells you what object 686238032Speter directory and Makefile it will use, but doesn't actually do 686338032Speter the make. 686438032Speter Do some additional checking on the contents of the qf file to try 686538032Speter to detect attacks against the qf file. In particular, 686638032Speter abort on any line beginning "From ", and add an "end of 686738032Speter file" line -- any data after that line is prohibited. 686838032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 686938032Speter choices. This can be overridden in the Makefile by using 687038032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 687138032Speter (to the extent that we know it) or by defining 687238032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 687338032Speter sendmail 8 to have more consistent installation instructions. 687438032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 687538032Speter of Sun Microsystems. 687638032Speter Improved symbol table hash function from Eric Wassenaar. This one 687738032Speter is at least 50% faster. 687838032Speter Fix problem that didn't notice that timeout on file open was a 687938032Speter transient error. Fix from Larry Parmelee of Cornell 688038032Speter University. 688138032Speter Allow comments (lines beginning with a `#') in files read for 688238032Speter classes. Suggested by Motonori Nakamura. 688338032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 688438032Speter of dropping out entirely. This makes testing some of the 688538032Speter name server lookups easier to deal with when there are 688638032Speter hung servers. From Motonori Nakamura. 688738032Speter Add new ${opMode} macro that is set to the current operation mode 688838032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 688938032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 689038032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 689138032Speter Kind of like queue-only mode (Odq) except it tries to avoid 689238032Speter any external service requests; for dial-on-demand hosts that 689338032Speter want to minimize DNS lookups when mail is being queued. For 689438032Speter this to work you will also have to make sure that gethostbyname 689538032Speter of your local host name does not do a DNS lookup. 689638032Speter Improved handling of "out of space" conditions from John Myers of 689738032Speter Carnegie Mellon. 689838032Speter Improved security for mailing to files on systems that have fchmod(2) 689938032Speter support. 690038032Speter Improve "cannot send message for N days" message -- now says "could 690138032Speter not send for past N days". Suggested by Tom Moore of AT&T 690238032Speter Global Information Solutions. 690338032Speter Less misleading Subject: line on messages sent to postmaster only. 690438032Speter From Motonori Nakamura. 690538032Speter Avoid duplicate error messages on bad command line flags.

Problem reported by David 691338032Speter James of British Telecom. 691438032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 691538032Speter from Alexander Dupuy of System Management ARTS. 691638032Speter Delete duplicates in MX lists -- believe it or not, there are sites 691738032Speter that list the same host twice in an MX list. This deletion 691838032Speter only works on adjacent preferences, so an MX list that 691938032Speter had A=5, B=10, A=15 would leave both As, but one that had 692038032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 692138032Speter just in case there is something weird I haven't thought of. 692238032Speter Suggested by Barry Shein of Software Tool & Die. 692338032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 701838032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 701938032Speter University of Brno (Czech Republic). 702038032Speter KSR OS 1.2.2 support from Todd Miller of the University 702138032Speter of Colorado. 702238032Speter UX4800 support from Kazuhisa Shimizu of NEC. 702338032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 702438032Speter in type ``btree'' maps. The semantics of this are undefined 702538032Speter for regular maps, but it can be useful for the user database. 702638032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 702738032Speter lookups while the rebuild is going on. There is a race 702838032Speter condition between the open(... O_TRUNC ...) and the lock 702938032Speter on the file, but it should be quite small. 703038032Speter SMRSH: sendmail restricted shell added to the release. This can 703138032Speter be used as an alternative to /bin/sh for the "prog" mailer, 703238032Speter giving the local administrator more control over what 703338032Speter programs can be run from sendmail. 703438032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 703538032Speter part of the release proper, and isn't fully supported; in 703638032Speter particular, it does not run on System V based systems and 703738032Speter never will. 703838032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 703938032Speter to allow rmail to compile on systems that don't have 704038032Speter function prototypes and systems that don't have snprintf. 704138032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 704238032Speter lists by transaction delay times so that addresses that 704338032Speter respond quickly get sent first. This is to prevent very 704438032Speter sluggish servers from delaying other peoples' mail. 704538032Speter Contributed by Tony Sanders of BSDI. 704638032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 704738032Speter of BSDI. This has a lot of comments to help people out. 704838032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 704938032Speter put this on the m4 command line. On GNU m4 (which 705038032Speter supports the __file__ primitive) you can run m4 in an 705138032Speter arbitrary directory -- use either: 705238032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 705338032Speter or 705438032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 705538032Speter On other versions of m4 that don't support __file__, you 705638032Speter can use: 705738032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 705838032Speter (Note the trailing slash on the _CF_DIR_ definition.) 705938032Speter Old versions of m4 will default to _CF_DIR_=.. for back 706038032Speter compatibility. 706138032Speter CONFIG: fix mail from <> so it will properly convert to 706238032Speter MAILER-DAEMON on local addresses. 706338032Speter CONFIG: fix code that was supposed to catch colons in host 706438032Speter names. Problem noted by John Gardiner Myers of CMU. 706538032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 706638032Speter From Paul Riddle of the University of Maryland, Baltimore 706738032Speter County. 706838032Speter CONFIG: Catch and reject "." as a host address. 706938032Speter CONFIG: Generalize domaintable to look up all domains, not 707038032Speter just unqualified ones. 707138032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 707238032Speter was never used and didn't work anyway. 707338032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 707438032Speter and d on all mailers in the UUCP class. 707538032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 707638032Speter look for an alias for "user+detail", then for "user+*", and 707738032Speter finally for "user". This is intended for forwarding mail 707838032Speter for system aliases such as root and postmaster to a 707938032Speter centralized hub. 708038032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 708138032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 708238032Speter The F=8 flag is also set on the "relay" mailer, since 708338032Speter this is expected to be another sendmail. 708438032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 708538032Speter the name of the UUCP_RELAY -- in some cases, this is the 708638032Speter wrong value (e.g., when we have local UUCP connections), 708738032Speter and this can create unreplyable addresses. From Chip 708838032Speter Rosenthal of Unicom. 708938032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 709064562Sgshapiro Received: header inserted into all messages. Suggested by 709138032Speter Gary Mills of the University of Manitoba. 709238032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 709343730Speter to get the old behavior. I did this upon observing 709438032Speter that almost everyone needed this feature, and that the 709538032Speter concept I was trying to make happen didn't work with 709638032Speter some user agents anyway. FEATURE(notsticky) still works, 709738032Speter but it is a no-op. 709838032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 709938032Speter names are sent, rather than immediately diagnosing them 710038032Speter as User Unknown. 710138032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 710238032Speter and RELAY_MAILER_ARGS to set the arguments for the 710338032Speter indicated mailers. All default to "IPC $h". Patch from 710438032Speter Larry Parmelee of Cornell University. 710538032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 710638032Speter on the client side" and F=P to get an appropriate 710738032Speter return-path. From Kimmo Suominen. 710838032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 710938032Speter as the local mailer. For addresses of the form "user+detail" 711038032Speter the "detail" part is passed to procmail via the -a flag. 711138032Speter Contributed by Kimmo Suominen. 711238032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 711338032Speter use from mailertables. This lets you execute arbitrary 711438032Speter procmail scripts. Contributed by Kimmo Suominen. 711538032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 711638032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 711738032Speter Paul Southworth of CICNet Systems Support. 711838032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 711938032Speter This causes the null return path to be rewritten as 712038032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 712138032Speter From Michael Hohmuth of Technische Universitat Dresden. 712238032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 712338032Speter list us as the best possible MX record to be treated as 712438032Speter though they were local (essentially, assume that they 712538032Speter are included in $=w). This can cause additional DNS 712638032Speter traffic, but is easier to administer if this fits your 712738032Speter local model. It does not work reliably if there are 712838032Speter multiple hosts that share the best MX preference. 712938032Speter Code contributed by John Oleynick of Rutgers. 713038032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 713138032Speter SHell) instead of /bin/sh as the program used for delivery 713238032Speter to programs. If an argument is included, it is used as 713338032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 713438032Speter assumed. 713538032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 713638032Speter size of messages to the local and procmail mailers 713738032Speter respectively. Contributed by Brad Knowles of the Defense 713838032Speter Information Systems Agency. 713938032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 714038032Speter (just like text outside of angle brackets) in order to 714138032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 714238032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 714338032Speter any real systems any more) and tweak the DOMAIN macro 714438032Speter so that it is less likely that users will accidentally use 714538032Speter the Berkeley defaults. Also, create some generic files 714638032Speter that really can be used in the real world. 714738032Speter CONFIG: Add new configuration macros to set character sets for 714838032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 714938032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 715038032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 715138032Speter The old name will still be accepted for a while at least. 715238032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 715338032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 715438032Speter As with all relays, it can be ``mailer:hostname''. Suggested 715538032Speter by Scott Hutton. 715638032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 715738032Speter by Barb Dijker of Labyrinth Computer Services. 715838032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 715938032Speter performance for large alias files, and this confused many 716038032Speter people. 716138032Speter CONFIG: Add confCF_VERSION to append local information to the 716238032Speter configuration version number displayed during SMTP startup. 716338032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 716438032Speter would only work when locally addressed. Fix from 716538032Speter Edvard Tuinder of Cistron Internet Services. 716638032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 716743730Speter "n" (CheckAliases) is set when rebuilding alias database. 716838032Speter Based on code contributed by Claude Marinier. 716938032Speter CONFIG: Allow mailertable to have values of the form 717038032Speter ``error:code message''. The ``code'' is a status code 717138032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 717238032Speter Contributed by David James <dwj@agw.bt.co.uk>. 717338032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 717438032Speter sender domains that will be replaced with the masquerade name. 717538032Speter These domains will not be treated as local, but if mail passes 717638032Speter through with sender addresses in those domains they will be 717738032Speter replaced by the masquerade name. These can also be specified 717838032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 717938032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 718038032Speter as well as the header. Substantial improvements to this 718138032Speter code were contributed by Per Hedeland. 718238032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 718338032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 718438032Speter by Kimmo Suominen. 718538032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 718638032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 718738032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 718838032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 718938032Speter UUCP addressing.

This caused UnixWare 733238032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 733338032Speter Novell Labs Europe. 733438032Speter Fix problem with static linking of local getopt routine when 733538032Speter using GNU's ld command. Fix from John Kennedy of 733638032Speter Cal State Chico. 733738032Speter It was possible to turn off privacy flags. Problem noted by 733838032Speter *Hobbit*. 733938032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 734038032Speter and Liudvikas Bukys. 734138032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 734238032Speter from Spider Boardman. 734338032Speter CONFIG: No changes (version number only, to keep it in sync 734438032Speter with the binaries). 734538032Speter 734664562Sgshapiro8.6.10/8.6.10 1995/02/10 734738032Speter SECURITY: Diagnose bogus values to some command line flags that 734838032Speter could allow trash to get into headers and qf files. 734938032Speter Validate the name of the user returned by the IDENT protocol. 735038032Speter Some systems that really dislike IDENT send intentionally 735138032Speter bogus information. Problem pointed out by Michael Bushnell 735238032Speter of the Free Software Foundation. Has some security 735338032Speter implications. 735438032Speter Fix a problem causing error messages about DNS problems when 735538032Speter the host name contained a percent sign to act oddly 735638032Speter because it was passed as a printf-style format string. 735738032Speter In some cases this could cause core dumps. 735838032Speter Avoid possible buffer overrun in returntosender() if error 735938032Speter message is quite long. From Fletcher Mattox of the 736038032Speter University of Texas. 736138032Speter Fix a problem that would silently drop "too many hops" error 736238032Speter messages if and only if you were sending to an alias. 736338032Speter From Jon Giltner of the University of Colorado and 736438032Speter Dan Harton of Oak Ridge National Laboratory. 736538032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 736638032Speter set and e->e_message was null. Fix from Bruce Nagel of 736738032Speter Data General. 736838032Speter Fix problem that can still cause df files to be left around 736938032Speter after "hop count exceeded" messages. Fix from Andrew 737038032Speter Chang and Shau-Ping Lo of SunSoft. 737138032Speter Fix a problem that can cause buffer overflows on very long 737238032Speter user names (as might occur if you piped to a program 737338032Speter with a lot of arguments). 737438032Speter Avoid returning an error and re-queueing if the host signature 737538032Speter is null; this can occur on addresses like ``user@.''. 737638032Speter Problem noted by Wesley Craig and the University of 737738032Speter Michigan. 737838032Speter Avoid possible calls to malloc(0) if MCI caching is turned 737938032Speter off. Bug fix from Pierre David of the Laboratoire 738038032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 738138032Speter Universite de Versailles - St Quentin, and Jacky 738238032Speter Thibault. 738338032Speter Make a local copy of the line being sent via senttolist() -- in 738438032Speter some cases, buffers could get trashed by map lookups 738538032Speter causing it to do unexpected things. This also simplifies 738638032Speter some of the map code. 738738032Speter CONFIG: No changes (version number only, to keep it in sync 738838032Speter with the binaries). 738938032Speter 739064562Sgshapiro8.6.9/8.6.9 1994/04/19 739138032Speter Do all mail delivery completely disconnected from any terminal. 739238032Speter This provides consistency with daemon delivery and 739338032Speter may have some security implications. 739438032Speter Make sure that malloc doesn't get called with zero size, 739538032Speter since that fails on some systems. Reported by Ed 739638032Speter Hill of the University of Iowa. 739738032Speter Fix multi-line values for $e (SMTP greeting message). Reported 739838032Speter by Mike O'Connor of Ford Motor Company. 739938032Speter Avoid syserr if no NIS domain name is defined, but the map it 740038032Speter is trying to open is optional. From Win Bent of USC. 740138032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 740238032Speter Hesiod support for UDB from Todd Miller of the University of 740338032Speter Colorado. Use "hesiod" as the service name in the U 740438032Speter option. 740538032Speter Fix a problem that failed to set the "authentic" host name (that 740638032Speter is, the one derived from the socket info) if you called 740738032Speter sendmail -bs from inetd. Based on code contributed by 740838032Speter Todd Miller (this problem was also reported by Guy Helmer 740938032Speter of Dakota State University). This also fixes a related 741038032Speter problem reported by Liudvikas Bukys of the University of 741138032Speter Rochester. 741238032Speter Parameterize "nroff -h" in all the Makefiles so people with 741338032Speter variant versions can use them easily. Suggested by 741438032Speter Peter Collinson of Hillside Systems. 741538032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 741638032Speter spaces between parameters instead of one. Reported by 741738032Speter Valdis Kletnieks of Virginia Tech. 741838032Speter Reduce the number of system calls during message collection by 741938032Speter using global timeouts around the collect() loop. This 742038032Speter code was contributed by Eric Wassenaar. 742138032Speter If the initial hostname name gathering results in a name 742238032Speter without a dot (usually caused by NIS misconfiguration) 742338032Speter and BIND is compiled in, directly access DNS to get 742438032Speter the canonical name. This should make life easier for 742538032Speter Solaris systems. If it still can't be resolved, and 742638032Speter if the name server is listed as "required", try again 742738032Speter in 30 seconds. If that also fails, exit immediately to 742838032Speter avoid bogus "config error: mail loops back to myself" 742938032Speter messages. 743038032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 743138032Speter message to explain how much space was available and 743238032Speter sound a bit less threatening. Suggested by Stan Janet 743338032Speter of the National Institute of Standards and Technology. 743438032Speter If mail is delivered to an alias that has an owner, deliver any 743538032Speter requested return-receipt immediately, and strip the 743638032Speter Return-Receipt-To: header from the subsequent message. 743738032Speter This prevents a certain class of denial of service 743838032Speter attack, arguably gives more reasonable semantics, and 743938032Speter moves things more towards what will probably become a 744038032Speter network standard. Suggested by Christopher Davis of 744138032Speter Kapor Enterprises. 744238032Speter Add a "noreceipts" privacy flag to turn off all return receipts 744338032Speter without recompiling. 744438032Speter Avoid printing ESMTP parameters as part of the error message 744538032Speter if there are errors during parsing. This change is 744638032Speter purely cosmetic. 744738032Speter Avoid sending out error messages during the collect phase of 744838032Speter SMTP; there is an MVS mailer from UCLA that gets 744938032Speter confused by this. Of course, I think it's their bug.... 745038032Speter Check for the $j macro getting undefined, losing a dot, or getting 745138032Speter lost from $=w in the daemon before accepting a connection; 745238032Speter if it is, it dumps state, prints a LOG_ALERT message, 745338032Speter and drops core for debugging. This is an attempt to 745438032Speter track down a bug that I thought was long since gone. 745538032Speter If you see this, please forward the log fragment to 745638032Speter sendmail@sendmail.ORG. 745738032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 745838032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 745938032Speter Wolfhugel. 746038032Speter Instead of trying to truncate the listen queue for the server 746138032Speter SMTP port when the load average is too high, just close 746238032Speter the port completely and reopen it later as needed. 746338032Speter This ensures that the other end gets a quick "connection 746438032Speter refused" response, and that the connection can be 746538032Speter recovered later. In particular, some socket emulations 746638032Speter seem to get confused if you tweak the listen queue 746738032Speter size around and can never start listening to connections 746838032Speter again. The down side is that someone could start up 746938032Speter another daemon process in the interim, so you could 747038032Speter have multiple daemons all not listening to connections; 747138032Speter this could in turn cause the sendmail.pid file to be 747238032Speter incorrect. A better approach might be to accept the 747338032Speter connection and give a 421 code, but that could break 747443730Speter other mailers in mysterious ways and have paging behavior 747538032Speter implications. 747638032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 747738032Speter set debugging on the wrong socket. From Eric Wassenaar. 747838032Speter When creating a df* temporary file, be sure you truncate any 747938032Speter existing data in the file -- otherwise system crashes 748038032Speter and the like could result in extra data being sent. 748138032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 748238032Speter doc directory. This includes some additional 748338032Speter information. 748438032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 748538032Speter of recipient envelope addresses. This should have been 748638032Speter handled by the $&h trick, but broke if people were 748738032Speter mixing domainized and UUCP addresses. They should 748838032Speter probably have converted all the way over to uucp-uudom 748938032Speter instead of uucp-{new,old}, but the failure mode was to 749038032Speter loop the mail, which was bad news. 749138032Speter Portability fixes: 749238032Speter Newer BSDI systems (several people). 749338032Speter Older BSDI systems from Christophe Wolfhugel. 749438032Speter Intergraph CLIX, from Paul Southworth of CICNet. 749538032Speter UnixWare, from Evan Champion. 749638032Speter NetBSD from Adam Glass. 749738032Speter Solaris from Quentin Campbell of the University of 749838032Speter Newcastle upon Tyne. 749938032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 750038032Speter Corporation. 750138032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 750238032Speter SunOS (it has setsid() and setvbuf() calls) from 750338032Speter Jonathan Kamens of OpenVision Technologies. 750438032Speter HP-UX from Tor Lillqvist. 750538032Speter New Files: 750638032Speter src/Makefile.CLIX 750738032Speter src/Makefile.NCR3000 750838032Speter doc/changes/Makefile 750938032Speter doc/changes/changes.me 751038032Speter doc/changes/changes.ps 751138032Speter 751264562Sgshapiro8.6.8/8.6.6 1994/03/21 751338032Speter SECURITY: it was possible to read any file as root using the 751438032Speter E (error message) option. Reported by Richard Jones; 751538032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 751638032Speter 751764562Sgshapiro8.6.7/8.6.6 1994/03/14 751838032Speter SECURITY: it was possible to get root access by using weird 751938032Speter values to the -d flag. Thanks to Alain Durand of 752038032Speter INRIA for forwarding me the notice from the bugtraq 752138032Speter list. 752238032Speter 752364562Sgshapiro8.6.6/8.6.6 1994/03/13 752438032Speter SECURITY: the ability to give files away on System V-based 752538032Speter systems proved dangerous -- don't run as the owner 752638032Speter of a :include: file on a system that allows giveaways. 752738032Speter Unfortunately, this also applies to determining a 752838032Speter valid shell. 752938032Speter IMPORTANT: Previous versions weren't expiring old connections 753038032Speter in the connection cache for a long time under some 753138032Speter circumstances. This could result in resource exhaustion, 753238032Speter both at your end and at the other end. This checks the 753338032Speter connections for timeouts much more frequently. From 753438032Speter Doug Anderson of NCSC. 753538032Speter Fix a glitch that snuck in that caused programs to be run as 753638032Speter the sender instead of the recipient if the mail was 753738032Speter from a local user to another local user. From 753838032Speter Motonori Nakamura of Kyoto University. 753938032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 754038032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 754138032Speter Bryan Costales of ICSI. 754238032Speter Change the method used to declare the "statfs" availability; 754338032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 754438032Speter tweaking in conf.c, there is a single #define called 754538032Speter SFS_TYPE which takes on one of six values (SFS_NONE 754638032Speter for no statfs availability, SFS_USTAT for the ustat(2) 754738032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 754838032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 754938032Speter statfs(2) call with the declarations in <sys/vfs.h>, 755038032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 755138032Speter Fix glitch in NetInfo support that could return garbage if 755238032Speter there was no "/locations/sendmail" property. From 755338032Speter David Meyer of the University of Virginia. 755438032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 755538032Speter to allow Linux to turn it off even though it is a 755638032Speter BSD-like system. 755738032Speter Allow setting of "ident" timeout to zero to turn off the ident 755838032Speter protocol entirely. 755938032Speter Make 7-bit stripping local to a connection (instead of to a 756038032Speter mailer); this allows you to specify that SMTP is a 756138032Speter 7-bit channel, but revert to 8-bit should it advertise 756238032Speter that it supports 8BITMIME. You still have to specify 756338032Speter mailer flag 7 to get this stripping at all. 756438032Speter Improve makesendmail script so it handles more cases automatically. 756538032Speter Tighten up restrictions on taking ownership of :include: files 756638032Speter to avoid problems on systems that allow you to give away 756738032Speter files. 756838032Speter Fix a problem that made it impossible to rebuild the alias 756938032Speter file if it was on a read-only file system. From 757038032Speter Harry Edmon of the University of Washington. 757138032Speter Improve MX randomization function. From John Gardiner Myers 757238032Speter of CMU. 757338032Speter Fix a minor glitch causing a bogus message to be printed (used 757438032Speter %s instead of %d in a printf string for the line number) 757538032Speter when a bad queue file was read. From Harry Edmon. 757638032Speter Allow $s to remain NULL on locally generated mail. I'm not 757738032Speter sure this is necessary, but a lot of people have complained 757838032Speter about it, and there is a legitimate question as to whether 757938032Speter "localhost" is legal as an 822-style domain. 758038032Speter Fix a problem with very short line lengths (mailer L= flag) in 758138032Speter headers. This causes a leading space to be added onto 758238032Speter continuation lines (including in the body!), and also 758338032Speter tries to wrap headers containing addresses (From:, To:, 758438032Speter etc) intelligently at the shorter line lengths. Problem 758538032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 758638032Speter Log the real user name when logging syserrs, since these can have 758738032Speter security implications. Suggested by several people. 758838032Speter Fix address logging of cached connections -- it used to always 758938032Speter log the numeric address as zero. This is a somewhat 759038032Speter bogus implementation in that it does an extra system 759138032Speter call, but it should be an inexpensive one. Fix from 759238032Speter Motonori Nakamura. 759338032Speter Tighten up handling of short syslog buffers even more -- there 759438032Speter were cases where the outgoing relay= name was too long 759538032Speter to share a line with delay= and mailer= logging. 759638032Speter Limit the overhead on split envelopes to one open file descriptor 759738032Speter per envelope -- previously the overhead was three 759838032Speter descriptors. This was in response to a problem reported 759938032Speter by P{r (Pell) Emanuelsson. 760038032Speter Fixes to better handle the case of unexpected connection closes; 760138032Speter this redirects the output to the transcript so the info 760238032Speter is not lost. From Eric Wassenaar. 760338032Speter Fix potential string overrun if you macro evaluate a string that 760438032Speter has a naked $ at the end. Problem noted by James Matheson 760538032Speter <jmrm@eng.cam.ac.uk>. 760638032Speter Make default error number on $#error messages 553 (``Requested 760738032Speter action not taken: mailbox name not allowed'') instead of 760838032Speter 501 (``Syntax error in parameters or arguments'') to 760938032Speter avoid bogus "protocol error" messages. 761038032Speter Strip off any existing trailing dot on names during $[ ... $] 761138032Speter lookup. This prevents it from ending up with two dots 761238032Speter on the end of dot terminated names. From Wesley Craig 761338032Speter of the University of Michigan and Bryan Costales of ICSI. 761438032Speter Clean up file class reading so that the debugging information is 761538032Speter more informative. It hadn't been using setclass, so you 761638032Speter didn't see the class items being added. 761738032Speter Avoid core dump if you are running a version of sendmail where 761838032Speter NIS is compiled in, and you specify an NIS map, but 761938032Speter NIS is not running. Fix from John Oleynick of 762038032Speter Rutgers. 762138032Speter Diagnose bizarre case where res_search returns a failure value, 762238032Speter but sets h_errno to a success value. 762338032Speter Make sure that "too many hops" messages are considered important 762438032Speter enough to send an error to the Postmaster (that is, the 762538032Speter address specified in the P option). This fix should 762638032Speter help problems that cause the df file to be left around 762738032Speter sometimes -- unfortunately, I can't seem to reproduce 762838032Speter the problem myself. 762938032Speter Avoid core dump (null pointer reference) on EXPN command; this 763038032Speter only occurred if your log level was set to 10 or higher 763138032Speter and the target account was an alias or had a .forward file. 763238032Speter Problem noted by Janne Himanka. 763338032Speter Avoid "denial of service" attacks by someone who is flooding your 763438032Speter SMTP port with bad commands by shutting the connection 763538032Speter after 25 bad commands are issued. From Kyle Jones of 763638032Speter UUNET. 763738032Speter Fix core dump on error messages with very long "to" buffers; 763838032Speter fmtmsg overflows the message buffer. Fixed by trimming 763938032Speter the to address to 203 characters. Problem reported by 764038032Speter John Oleynick. 764138032Speter Fix configuration for HASFLOCK -- there were some spots where 764238032Speter a #ifndef was incorrectly #ifdef. Pointed out by 764338032Speter George Baltz of the University of Maryland. 764438032Speter Fix a typo in savemail() that could cause the error message To: 764538032Speter lists to be incorrect in some places. From Motonori 764638032Speter Nakamura. 764738032Speter Fix a glitch that can cause duplicate error messages on split 764838032Speter envelopes where an address on one of the lists has a 764938032Speter name server failure. Fix from Voradesh Yenbut of the 765038032Speter University of Washington. 765138032Speter Fix possible bogus pointer reference on ESMTP parameters that 765238032Speter don't have an ``=value'' part. 765338032Speter CNAME loops caused an error message to be generated, but also 765438032Speter re-queued the message. Changed to just re-queue the 765538032Speter message (it's really hard to just bounce it because 765638032Speter of the weird way the name server works in the presence 765738032Speter of CNAME loops). Problem noted by James M.R.Matheson 765838032Speter of Cambridge University. 765938032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 766038032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 766138032Speter user name. Suggested by Andreas Stolcke of ICSI. 766238032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 766338032Speter override it easily in the Makefile -- that is, you can 766438032Speter turn it off using -DNAMED_BIND=0. 766538032Speter If a gethostbyname(...) of an address with a trailing dot fails, 766638032Speter try it without the trailing dot. This is because if 766738032Speter you have a version of gethostbyname() that falls back 766838032Speter to NIS or the /etc/hosts file it will fail to find 766938032Speter perfectly reasonable names that just don't happen to 767038032Speter be dot terminated in the hosts file. You don't want to 767138032Speter strip the dot first though because we're trying to ensure 767238032Speter that country names that match one of your subdomains get 767338032Speter a chance. 767438032Speter PRALIASES: fix bogus output on non-null-terminated strings. 767538032Speter From Bill Gianopoulos of Raytheon. 767638032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 767738032Speter This was in code intended to only catch the self-literal 767838032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 767938032Speter IP address), but the code was broken. However, it will 768038032Speter still do this if $M is defined; this is necessary to 768138032Speter get client configurations to work (sigh). Note that this 768238032Speter means that $M overrides :mailname entries in the user 768338032Speter database! Problem noted by Paul Southworth. 768438032Speter CONFIG: Fix definition of Solaris help file location. From 768538032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 768638032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 768738032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 768838032Speter and USENET_MAILER_MAX to tweak the maximum message 768938032Speter size for various mailers. 769038032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 769138032Speter instead of assuming that it is "inews" for consistency 769238032Speter with other mailers. From Michael Corrigan of UC San Diego. 769338032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 769438032Speter qualify the address in the SMTP envelope as user@{relay|hub} 769538032Speter instead of user@$j. From Bill Wisner of The Well. 769638032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 769738032Speter CONFIG: Don't turn off case mapping of user names in the local 769838032Speter mailer for IRIX. This was different than most every other 769938032Speter system. 770038032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 770138032Speter envelope. Noted by Thierry Besancon 770238032Speter <besancon@excalibur.ens.fr>. 770338032Speter CONFIG: Don't include -z by default on uux line -- most systems 770438032Speter don't want it set by default. Pointed out by Philippe 770538032Speter Michel of Thomson CSF. 770638032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 770738032Speter host name was foo.bar.ray.com and you matched against 770838032Speter ".ray.com", the old implementation bound %1 to "bar" 770938032Speter instead of "foo.bar". Also, allow "." in the mailertable 771038032Speter to match anything -- essentially, take over SMART_HOST. 771138032Speter This also moves matching of explicit local host names 771238032Speter before the mailertable so they don't have to be special 771338032Speter cased in the mailertable data. Reported by Bill 771438032Speter Gianopoulos of Raytheon; the fix for the %1 binding 771538032Speter problem was contributed by Nicholas Comanos of the 771638032Speter University of Sydney. 771738032Speter CONFIG: Don't include "root" in class $=L (users to deliver 771838032Speter locally, even if a hub or relay exists) by default. 771938032Speter This is because of the known bug where definition of 772038032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 772138032Speter both and deliver into the local mailbox. 772238032Speter CONFIG: Move up bitdomain and uudomain handling so that they 772338032Speter are done before .UUCP class matching; uudomain was 772438032Speter reported as ineffective before. This also frees up 772538032Speter diversion 8 for future use. Problem reported by Kimmo 772638032Speter Suominen. 772738032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 772838032Speter into host names. As pointed out by Jonathan Kamens, 772938032Speter these are often used because either the forward or reverse 773038032Speter mapping is broken; this translation makes it broken again. 773138032Speter DOC: Clarify $@ and $: in the Install & Op Guide.

From 775838032Speter Bob Campbell at U.C. Berkeley. 775938032Speter Security fix: group ids were not completely set when programs 776038032Speter were invoked. This caused programs to have group 776138032Speter permissions they should not have had (usually group 776238032Speter daemon instead of their own group). In particular, 776338032Speter Perl scripts would refuse to run. 776438032Speter Security: check to make sure files that are written are not 776538032Speter symbolic links (at least under some circumstances). 776638032Speter Although this does not respond to a specific known 776738032Speter attack, it's just a good idea. Suggested by 776838032Speter Christian Wettergren. 776938032Speter Security fix: if a user had an NFS mounted home directory on 777038032Speter a system with a restricted shell listed in their 777138032Speter /etc/passwd entry, they could still execute any 777238032Speter program by putting that in their .forward file. 777338032Speter This fix prevents that by insisting that their shell 777438032Speter appear in /etc/shells before allowing a .forward to 777538032Speter execute a program or write a file. You can disable 777638032Speter this by putting "*" in /etc/shells. It also won't 777738032Speter permit world-writable :include: files to reference 777838032Speter programs or files (there's no way to disable this). 777943730Speter These behaviors are only one level deep -- for 778038032Speter example, it is legal for a world-writable :include: 778138032Speter file to reference an alias that writes a file, on 778238032Speter the assumption that the alias file is well controlled. 778338032Speter Security fix: root was not treated suspiciously enough when 778438032Speter looking into subdirectories. This would potentially 778538032Speter allow a cracker to examine files that were publicly 778638032Speter readable but in a non-publicly searchable directory. 778738032Speter Fix a problem that causes an error on QUIT on a cached 778838032Speter connection to create problems on the current job. 778938032Speter These are typically unrelated, so errors occur in 779038032Speter the wrong place. 779138032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 779238032Speter runs more responsive to load average, and fixes a 779338032Speter problem that ignored the load average in locally 779438032Speter generated mail. From Eric Wassenaar. 779538032Speter Fix possible core dump on aliases with null LHS. From 779638032Speter John Orthoefer of BB&N. 779738032Speter Revert to using flock() whenever possible -- there are just 779838032Speter too many bugs in fcntl() locking, particularly over 779938032Speter NFS, that cause sendmail to fail in perverse ways. 780038032Speter Fix a bug that causes the connection cache to get confused 780138032Speter when sending error messages. This resulted in 780238032Speter "unexpected close" messages. It should fix itself 780338032Speter on the following queue run. Problem noted by 780438032Speter Liudvikas Bukys of the University of Rochester. 780538032Speter Include $k in $=k as documented in the Install & Op Guide. 780638032Speter This seems odd, but it was documented.... From 780738032Speter Michael Corrigan of UCSD. 780838032Speter Fix problem that caused :include:s from alias files to be 780938032Speter forced to be owned by root instead of daemon 781038032Speter (actually DefUid). From Tim Irvin. 781138032Speter Diagnose unrecognized I option values -- from Mortin Forssen 781238032Speter of the Chalmers University of Technology. 781338032Speter Make "error" mailer work consistently when there is no error 781438032Speter code associated with it -- previously it returned OK 781538032Speter even though there was a real problem. Now it assumes 781638032Speter EX_UNAVAILABLE. 781738032Speter Fix bug that caused the last header line of messages that had 781838032Speter no body and which were terminated with EOF instead of 781938032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 782038032Speter Fix core dump on SMTP mail to programs that failed -- it tried 782138032Speter to go to a "next MX host" when none existed, causing 782238032Speter a core dump. From der Mouse at McGill University. 782338032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 782438032Speter this makes it easier to turn it off (using 782538032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 782638032Speter Fix YP_MASTER_NAME store to use the unupdated result of 782738032Speter gethostname() (instead of myhostname(), which tries 782838032Speter to fully qualify the name) to be consistent with 782938032Speter SunOS. If your hostname is unqualified, this fixes 783038032Speter transfers to slave servers. Bug noted by Keith 783138032Speter McMillan of Ameritech Services, Inc. 783238032Speter Fix Ultrix problem: gethostbyname() can return a very large 783338032Speter (> 500) h_length field, which causes the sockaddr 783438032Speter to be trashed. Use the size of the sockaddr instead. 783538032Speter Fix from Bob Manson of Ohio State. 783638032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 783738032Speter defined -- this confuses gethostbyname on hosts 783838032Speter file lookups, which doesn't understand the trailing 783938032Speter dot convention. 784038032Speter Log SMTP server subprocesses that die with a signal instead 784138032Speter of from a clean exit. 784238032Speter If you don't have option "I" set, don't assume that a DNS 784338032Speter "host unknown" message is authoritative -- it 784438032Speter might still be found in /etc/hosts. 784538032Speter Fix a problem that would cause Deferred: messages to be sent 784638032Speter as the subject of an error message, even though the 784738032Speter actual cause of a message was more severe than that. 784838032Speter Problem noted by Chris Seabrook of OSSI. 784938032Speter Fix race condition in DBM alias file locking. From Kyle 785038032Speter Jones of UUNET. 785138032Speter Limit delivery syslog line length to avoid bugs in some 785238032Speter versions of syslog(3). This adds a new compile time 785338032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 785438032Speter University, which is in turn derived from IDA. 785538032Speter Fix quotes inside of comments in addresses -- previously 785638032Speter it insisted that they be balanced, but the 822 spec 785738032Speter says that they should be ignored. 785838032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 785938032Speter debugging). This also evaluates ruleset 89, if set 786038032Speter (with the null input), and logs the result. This 786138032Speter should be used sparingly, since the rewrite process 786238032Speter is not reentrant. 786338032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 786438032Speter documented in the Bat Book. 786538032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 786638032Speter return an error message and did not requeue the message. 786738032Speter Fix based on code from Roland Dirlewanger of 786838032Speter Reseau Regional Aquarel, Bordeaux, France. 786938032Speter Fix a problem that caused a seg fault if you got a 421 error 787038032Speter code during some parts of connection initialization. 787138032Speter I've only seen this when talking to buggy mailers on 787238032Speter the other end, but it shouldn't give a seg fault in 787338032Speter any case. From Amir Plivatsky. 787438032Speter Fix core dump caused by a ruleset call that returns null. 787538032Speter Fix from Bryan Costales of ICSI. 787638032Speter Full-Name: field was being ignored.

Noted by William C Fenner of 791538032Speter the NRL Connection Machine Facility. 791638032Speter Fix a problem that could cause a core dump if the input sequence 791738032Speter had (or somehow acquired) a \231 character. 791838032Speter Make sure that route-addrs always have <angle brackets> around 791938032Speter them in non-SMTP envelopes (SMTP envelopes already do 792038032Speter this properly). 792138032Speter Avoid weird headers on unbalanced punctuation of the form: 792238032Speter ``Joe User <user)'' -- this caused reference to the 792338032Speter null macro. Fix from Rick McCarty of IO.COM. 792438032Speter Fix a problem that caused an alias "user: user@local.host" to 792538032Speter not have the QNOTREMOTE bit set; this caused configs 792638032Speter to act as if FEATURE(notsticky) was defined even when 792738032Speter it was not. The effect of the problem was to make it 792838032Speter very hard to to set up satellite sites that had a few 792938032Speter local accounts, with everything else forwarded to a 793038032Speter corporate hub. Reported by Detlef Drewanz of the 793138032Speter University of Rostock and Mark Frost of NCD. 793238032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 793338032Speter addresses. This is more efficient (fewer name server 793438032Speter calls) and fixes certain unusual configurations, such 793538032Speter as those that have ruleset 4 do something that is 793638032Speter non-idempotent unless a mailer-specific ruleset did 793738032Speter something else.

Briefly, if you are sending to host 800638032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 800738032Speter "foo!baz" remains "foo!baz", and anything else has 800838032Speter the local name prepended. 800938032Speter CONFIG: portability fixes for HP-UX. 801038032Speter DOC: several minor problems fixed in the Install & Op Guide. 801138032Speter MAKEMAP: fix core dump problem on lines that are too long or 801238032Speter which lack newline. From Mark Delany. 801338032Speter MAILSTATS: print sums of columns (total messages & kbytes 801438032Speter in and out of the system). From Tom Ferrin of UC 801538032Speter San Francisco Computer Graphics Lab. 801638032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 801738032Speter On HP-UX, /etc/sendmail.cf has been moved to 801838032Speter /usr/lib/sendmail.cf to match HP sendmail. 801938032Speter Permissions have been tightened up on world-writable 802038032Speter :include: files and accounts that have shells 802138032Speter that are not listed in /etc/shells. This may 802238032Speter cause some .forward files that have worked 802338032Speter before to start failing. 802438032Speter SIGUSR1 dumps some state to the log. 802538032Speter NEW FILES: 802638032Speter src/Makefile.DGUX 802738032Speter src/Makefile.Dynix 802838032Speter src/Makefile.FreeBSD 802938032Speter src/Makefile.Mach386 803038032Speter src/Makefile.NetBSD 803138032Speter src/Makefile.RISCos 803238032Speter src/Makefile.SCO 803338032Speter src/Makefile.SVR4 803438032Speter src/Makefile.Titan 803538032Speter cf/mailer/pop.m4 803638032Speter cf/ostype/bsdi1.0.m4 803738032Speter cf/ostype/dgux.m4 803838032Speter cf/ostype/dynix3.2.m4 803938032Speter cf/ostype/sco3.2.m4 804038032Speter makemap/Makefile.dist 804138032Speter praliases/Makefile.dist 804238032Speter 804364562Sgshapiro8.6.4/8.6.4 1993/10/31 804438032Speter Repair core-dump problem (write to read-only memory segment) 804538032Speter if you fall back to the return-to-Postmaster case in 804638032Speter savemail. Problem reported by Richard Liu. 804738032Speter Immediately diagnose bogus sender addresses in SMTP. This 804838032Speter makes quite certain that crackers can't use this 804938032Speter class of attack. 805038032Speter Reliability Fix: check return value from fclose() and fsync() 805138032Speter in a few critical places. 805238032Speter Minor problem in initsys() that reversed a condition for 805338032Speter redirecting the output channel on queue runs. It's 805438032Speter not clear this code even does anything. From Eric 805538032Speter Wassenaar of the Dutch National Institute for Nuclear 805638032Speter and High-Energy Physics. 805738032Speter Fix some problems that caused queue runs to do "too much work", 805838032Speter such as double-reading the Errors-To: header. From 805938032Speter Eric Wassenaar. 806038032Speter Error messages on writing the temporary file (including the 806138032Speter data file) were getting suppressed in SMTP -- this 806238032Speter fix causes them to be properly reported. From Eric 806338032Speter Wassenaar. 806438032Speter Some changes to support AF_UNIX sockets -- this will only 806538032Speter really become relevant in the next release, but some 806638032Speter people need it for local patches. From Michael 806738032Speter Corrigan of UC San Diego. 806838032Speter Use dynamically allocated memory (instead of static buffers) 806938032Speter for macros defined in initsys() and settime(); since 807038032Speter these can have different values depending on which 807138032Speter envelope they are in. From Eric Wassenaar. 807238032Speter Improve logging to show ctladdr on to= logging; this tells you 807338032Speter what uid/gid processes ran as. 807438032Speter Fix a problem that caused error messages to be discarded if 807538032Speter the sender address was unparseable for some reason; 807638032Speter this was supposed to fall back to the "return to 807738032Speter postmaster" case. 807838032Speter Improve aliaswait backoff algorithm. 807938032Speter Portability patches for Linux (8.6.3 required another header 808038032Speter file) (from Karl London) and SCO UNIX. 808138032Speter CONFIG: patch prog mailer to not strip host name off of envelope 808238032Speter addresses (so that it matches local again). From 808338032Speter Christopher Davis. 808438032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 808538032Speter this prevents uux from seeing lines with null names like 808638032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 808738032Speter Nakamura of Kyoto University. 808838032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 808938032Speter it shouldn't fail miserably. From Motonori Nakamura. 809038032Speter 809164562Sgshapiro8.6.2/8.6.2 1993/10/15 809238032Speter Put a "successful delivery" message in the transcript for 809338032Speter addresses that get return-receipts. 809438032Speter Put a prominent "this is only a warning" message in warning 809538032Speter messages -- some people don't read carefully enough 809638032Speter and end up sending the message several times. 809738032Speter Include reason for temporary failure in the "warning" return 809838032Speter message. Currently, it just says "cannot send for 809938032Speter four hours". 810038032Speter Fix the "Original message received" time generated for 810138032Speter returntosender messages. It was previously listed as 810238032Speter the current time. Bug reported by Eric Hagberg of 810338032Speter Cornell University Medical College. 810438032Speter If there is an error when writing the body of a message, 810538032Speter don't send the trailing dot and wait for a response 810638032Speter in sender SMTP, as this could cause the connection to 810738032Speter hang up under some bizarre circumstances. From Eric 810838032Speter Wassenaar. 810938032Speter Fix some server SMTP synchronization problems caused when 811038032Speter connections fail during message collection. From 811138032Speter Eric Wassenaar. 811238032Speter Fix a problem that can cause srvrsmtp to reject mail if the 811338032Speter name server is down -- it accepts the RCPT but rejects 811438032Speter the DATA command. Problem reported by Jim Murray of 811538032Speter Stratus. 811638032Speter Fix a problem that can cause core dumps if the config file 811738032Speter incorrectly resolves to a null hostname. Reported by 811838032Speter Allan Johannesen of WPI. 811938032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 812038032Speter by non-root users were not put into 812138032Speter X-Authentication-Warning:s as intended because the 812243730Speter config file hadn't set the PrivacyOptions yet. Fix 812338032Speter from Sven-Ove Westberg of the University of Lulea. 812438032Speter Under very odd circumstances, the alias file rebuild code 812538032Speter could get confused as to whether a database was 812638032Speter open or not. 812738032Speter Check "vendor code" on the end of V lines -- this is 812838032Speter intended to provide a hook for vendor-specific 812938032Speter configuration syntax. (This is a "new feature", 813038032Speter but I've made an exception to my rule in a belief 813138032Speter that this is a highly exceptional case.) 813238032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 813338032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 813438032Speter (from Jon Forrest of UC Berkeley) 813538032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 813638032Speter 813764562Sgshapiro8.6.1/8.6 1993/10/08 813838032Speter Portability fixes for A/UX and Encore UMAX V. 813938032Speter Fix error message handling -- if you had a name server down 814038032Speter causing an error during parsing, that message was never 814138032Speter propagated to the queue file. 814238032Speter 814364562Sgshapiro8.6/8.6 1993/10/05 814438032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 814538032Speter conf.h (other systems have the same bug). 814638032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 814738032Speter getdtablesize() instead of sysconf(); a disturbingly 814838032Speter large number of systems defined _SC_OPEN_MAX in the 814938032Speter header files but don't have the syscall. 815038032Speter Another patch to really truly ignore MX records in getcanonname 815138032Speter if trymx == FALSE. 815238032Speter Fix problem that caused the "250 IAA25499 Message accepted for 815338032Speter delivery" message to be omitted if there was an error 815438032Speter in the header of the message (e.g., a bad Errors-To: 815538032Speter line). Pointed out by Michael Corrigan of UCSD. 815638032Speter Announce name of host we are chatting when we get errors; this 815738032Speter is an IDA-ism suggested by Christophe Wolfhugel. 815838032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 815938032Speter Australian Artificial Intelligence Institute), SCO Unix 816038032Speter (from Murray Kucherawy of Hookup Communication Corp.), 816138032Speter NeXT (from Vince DeMarco and myself), Linux (from 816238032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 816338032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 816438032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 816538032Speter Some changes to get around gcc optimizer bugs. From Takahiro 816638032Speter Kanbe. 816738032Speter Fix error recovery in queueup if another tf file of the same 816838032Speter name already exists. Problem stumbled over by Bill 816938032Speter Wisner of The Well. 817038032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 817138032Speter Problem noted by Keith McMillan of Ameritech Services. 817238032Speter Deal with group permissions properly when opening .forward and 817338032Speter :include: files. This relaxes the 8.1C restrictions 817438032Speter slightly more. This includes proper setting of groups 817538032Speter when reading :include: files, allowing you to read some 817638032Speter files that you should be able to read but have previously 817738032Speter been denied unless you owned them or they had "other" 817838032Speter read permission. 817938032Speter Make certain that $j is in $=w (after the .cf is read) so that 818038032Speter if the user is forced to override some silly system, 818138032Speter MX suppression will still work. 818238032Speter Fix a couple of efficiency problems where newstr was double- 818338032Speter calling expensive routines. In at least one case, it 818438032Speter wasn't guaranteed that they would always return the 818538032Speter same result. Problem noted by Christophe Wolfhugel. 818638032Speter Fix null pointer dereference in putoutmsg -- only on an error 818738032Speter condition from a non-SMTP mailer. From Motonori 818838032Speter Nakamura. 818938032Speter Macro expand "C" line class definitions before scanning so that 819038032Speter "CX $Z" works. 819138032Speter Fix problem that caused error message to be sent while still 819238032Speter trying to send the original message if the connection 819338032Speter is closed during a DATA command after getting an error 819438032Speter on an RCPT command (pretty obscure). Problem reported 819538032Speter by John Myers of CMU. 819638032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 819738032Speter term bug. 819838032Speter Fix a nasty bug causing core dumps when returning the "warning: 819938032Speter cannot deliver for N hours -- will keep trying" message; 820043730Speter it only occurred if you had PostmasterCopy set and 820138032Speter only on some architectures. Although sendmail would 820238032Speter keep trying, it would send error messages on each 820338032Speter queue interval. This is an important fix. 820438032Speter Allow u and g options to take user and group names respectively. 820538032Speter Don't do a chdir into the queue directory in -bt mode to make 820638032Speter ruleset testing a bit easier. 820738032Speter Don't allow users to turn off logging (using -oL) on the command 820838032Speter line -- command line can only raise, not lower, logging 820938032Speter level. 821038032Speter Set $u to the original recipient on the SMTP transaction or on 821138032Speter the command line. This is only done if there is exactly 821238032Speter one recipient. Technically, this does not meet the 821338032Speter specs, because it does not guarantee a domain on the 821438032Speter address. 821538032Speter Fix a problem that dumped error messages on bad addresses if 821638032Speter you used the -t flag. Problem noted by Josh Smith of 821738032Speter Harvey Mudd College. 821838032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 821938032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 822038032Speter avoid the problem of people who use angle brackets in 822138032Speter their full name information. 822238032Speter Fix a null pointer dereference if you set option "l", have 822338032Speter an Errors-To: header in the message, and have Errors-To: 822438032Speter defined in the config file H lines. From J.R. Oldroyd. 822538032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 822638032Speter wrong when compiling. Suggested by Rick McCarty of TI. 822738032Speter Fix a problem that could pass negative SIZE parameter if the 822838032Speter df file got lost; this would cause servers to always 822938032Speter give a temporary failure, making the problem even worse. 823038032Speter Problem noted by Allan Johannesen of WPI. 823138032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 823238032Speter protocol timeouts (30s default). Requested by Murray 823338032Speter Kucherawy of HookUp Communication Corp. to handle bogus 823438032Speter PC TCP/IP implementations. 823538032Speter Change $w default definition to be just the first component of 823638032Speter the domain name on config level 5. The $j macro defaults 823738032Speter to the FQDN; $m remains as before. This lets well-behaved 823838032Speter config files use any of the short, long, or subdomain 823938032Speter names. 824038032Speter Add makesendmail script in src to try to automate multi-architecture 824138032Speter builds. I know, this is sub-optimal, but it is still 824238032Speter helpful. 824338032Speter Fix very obscure race condition that can cause a queue run to 824438032Speter get a queue file for an already completed job. This 824538032Speter problem has existed for years. Problem noted by the 824638032Speter long suffering Allan Johannesen of WPI. 824738032Speter Fix a problem that caused the raw sender name to be passed to 824838032Speter udbsender instead of the canonified name -- this caused 824938032Speter it to sometimes miss records that it should have found. 825038032Speter Relax check of name on HELO packet so that a program using -bs 825138032Speter that claims to be itself works properly. 825238032Speter Restore rewriting of $: part of address through 2, R, 4 in 825338032Speter buildaddr -- this requires passing a lot of flags to get 825438032Speter it right. Unlike old versions, this ONLY rewrites 825538032Speter recipient addresses, not sender addresses. 825638032Speter Fix a bug that caused core dumps in config files that cannot 825738032Speter resolve /file/name style addresses. Fix from Jonathan 825838032Speter Kamens of OpenVision Technologies. 825938032Speter Fix problem with fcntl locking that can cause error returns to 826038032Speter be lost if the lock is lost; this required fully 826138032Speter queueing everything, dropping the envelope (so errors 826238032Speter would get returned), and then re-reading the queue from 826338032Speter scratch. 826438032Speter Fix a problem that caused aliases that redefine an otherwise 826538032Speter true address to still send to the original address 826638032Speter if and only if the alias failed in certain bizarre 826738032Speter ways (e.g, if they pointed at a list:; syntax address). 826838032Speter Problem pointed out by Jonathan Kamens. 826938032Speter Remove support for frozen configuration files. They caused 827038032Speter more trouble than it was worth. 827138032Speter Fix problem that can cause error messages to get ignored when 827238032Speter using both -odb and -t flags. Problem noted by Rob 827338032Speter McNicholas at U.C. Berkeley. 827438032Speter Include all "normal" variations on hostname in $=w. For example, 827538032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 827638032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 827738032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 827838032Speter the queue. 827938032Speter Reset SmtpPhase global on initial connection creation so that 828038032Speter messages don't come out with stale information. 828138032Speter Pass an "ext" argument to lockfile so that error/log messages 828238032Speter will properly reflect the true filename being locked. 828338032Speter Put all [...] address forms into $=w -- this eliminates the need 828438032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 828538032Speter Myers of CMU. 828638032Speter Fix a bug that can cause qf files to be left around even after 828738032Speter an SMTP RSET command. Problem and fix from Michael 828838032Speter Corrigan. 828943730Speter Don't send a PostmasterCopy to errors when the Precedence: is 829038032Speter negative. Error reports still go to the envelope 829138032Speter sender address. 829238032Speter Add LA_SHORT for load averages. 829338032Speter Lock sendmail.st file when posting statistics. 829438032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 829538032Speter set the size of the TCP send and receive buffers; if you 829638032Speter run over a slow slip line you may need to set these down 829738032Speter (although it would be better to fix the SLIP implementation 829838032Speter so that it's not necessary to recompile every program 829938032Speter that does bulk data transfer). 830038032Speter Allow null defaults on $( ... $) lookups. Problem reported by 830138032Speter Amir Plivatsky. 830238032Speter Diagnose crufty S and V config lines. This resulted from an 830338032Speter observation that some people were using the SITE macro 830438032Speter without the SITECONFIG macro first, which was causing 830538032Speter bogus config files that were not caught. 830638032Speter Fix makemap -f flag to turn off case folding (it was turning it 830738032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 830838032Speter Fix a problem that caused multiple error messages to be sent if 830938032Speter you used "sendmail -t -oem -odb", your system uses fcntl 831038032Speter locking, and one of the recipient addresses is unknown. 831138032Speter Reset uid earlier in include() so that recursive .forwards or 831238032Speter :include:s don't use the wrong uid. 831338032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 831438032Speter called, the code to recover the descriptor was broken. 831538032Speter This sometimes (only sometimes) caused problems with the 831638032Speter alias file. Fix from Motonori Nakamura. 831738032Speter Fix a problem that caused aliaswait to go into infinite recursion 831838032Speter if the @:@ metasymbol wasn't found in the alias file. 831938032Speter Improve error message on newaliases if database files cannot be 832038032Speter opened or if running with no database format defined. 832138032Speter Do a better estimation of the size of error messages when NoReturn 832238032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 832338032Speter Fix a problem causing the "c" option (don't connect to expensive 832438032Speter mailers) to be ignored in SMTP. Problem noted and the 832538032Speter solution suggested by Robert Elz of The University of 832638032Speter Melbourne. 832738032Speter Improve connection caching algorithm by passing "[host]" to 832838032Speter hostsignature, which strips the square brackets and 832938032Speter returns the real name. This allows mailertable entries 833038032Speter to match regular entries. 833138032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 833238032Speter feature, even if it doesn't work right. 833338032Speter Catch and log attempts to try the "wiz" command in server SMTP. 833438032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 833538032Speter Be more generous at assigning $z to the home directory -- do this 833638032Speter for programs that are specified through a .forward file. 833738032Speter Fix from Andrew Chang of Sun Microsystems. 833838032Speter Always save a fatal error message in preference to a non-fatal 833938032Speter error message so that the "subject" line of return 834038032Speter messages is the best possible. 834138032Speter CONFIG: reduce the number of quotes needed to quote configuration 834238032Speter parameters with commas: two quotes should work now, e.g., 834338032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 834438032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 834538032Speter connections (domain-ized UUCP). 834638032Speter CONFIG: fix bug in default maps (-o must be before database file 834764562Sgshapiro name). Pointed out by Christophe Wolfhugel. 834838032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 834938032Speter DNS. This would presumably be used in UUCP islands. 835038032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 835138032Speter CONFIG: log $u in Received: line. This is in technical violation 835238032Speter of the standards, since it doesn't guarantee a domain 835338032Speter on the address. 835438032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 835538032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 835638032Speter the "m" flag should you want it. Apparently some Solaris 2.2 835738032Speter installations can't handle multiple local recipients. 835838032Speter Problem noted by Josh Smith. 835938032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 836038032Speter CONFIG: change default version level from 4 to 5. 836138032Speter CONFIG: add FEATURE(nullclient) to create a config file that 836238032Speter forwards all mail to a hub without ever looking at the 836338032Speter addresses in any detail. 836438032Speter CONFIG: properly strip mailer: information off of relays when 836538032Speter used to change .BITNET form into %-hack form. 836638032Speter CONFIG: fix a problem that caused infinite loops if presented 836738032Speter with an address such as "!foo". 836838032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 836938032Speter the reverse "PTR" mapping is broken. There's a better 837038032Speter way to do this, but the change is fairly major and I 837138032Speter want to hold it for another release. Problem noted by 837238032Speter Bret Marquis. 837338032Speter 837464562Sgshapiro8.5/8.5 1993/07/23 837538032Speter Serious bug: if you used a command line recipient that was unknown 837638032Speter sendmail would not send a return message (it was treating 837738032Speter everything as though it had an SMTP-style client that 837838032Speter would do the return itself). Problem noted by Josh Smith. 837938032Speter Change "trymx" option in getcanonname() to ignore all MX data, 838038032Speter even during a T_ANY query. This actually didn't break 838138032Speter anything, because the only time you called getcanonname 838238032Speter with !trymx was if you already knew there were no MX 838338032Speter records, but it is somewhat cleaner. From Motonori 838438032Speter Nakamura. 838538032Speter Don't call getcanonname from getmxrr if you already know there 838638032Speter are no DNS records matching the name. 838738032Speter Fix a problem causing error messages to always include "The 838838032Speter original message was received ... from localhost". 838938032Speter The correct original host information is now included. 839038032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 839138032Speter version of "test" doesn't have the -x flag). Change it 839238032Speter to use -f instead. From John Myers. 839338032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 839438032Speter esmtp -- it should be smtp. 839538032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 839638032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 839738032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 839838032Speter this cleans up the configs somewhat. This fixes a serious 839938032Speter problem that caused route-addrs to get mistaken as relays, 840038032Speter pointed out by John Myers. WARNING: this also causes 840138032Speter the default on SMART_HOST to change from "suucp" to 840238032Speter "relay" if you have MAILER(smtp) specified. 840338032Speter 840464562Sgshapiro8.4/8.4 1993/07/22 840538032Speter Add option `w'. If you receive a message that comes to you because 840638032Speter you are the best (lowest preference) target of an MX, and 840738032Speter you haven't explicitly recognized the source MX host in 840838032Speter your .cf file, this option will cause you to try the target 840938032Speter host directly (as if there were no MX for it at all). If 841038032Speter `w' is not set, this case is a configuration error. 841138032Speter Beware: if `w' is set, senders may get bogus errors like 841238032Speter "message timed out" or "host unknown" for problems that 841338032Speter are really configuration errors. This option is 841438032Speter disrecommended, provided only for compatibility with 841538032Speter UIUC sendmail. 841638032Speter Fix a problem that caused the incoming socket to be left open 841738032Speter when sendmail forks after the DATA command. This caused 841838032Speter calling systems to wait in FIN_WAIT_2 state until the 841938032Speter entire list was processed and the child closed -- a 842038032Speter potentially prodigious amount of time. Problem noted 842138032Speter by Neil Rickert. 842238032Speter Fix problem (created in 6.64) that caused mail sent to multiple 842338032Speter addresses, one of which was a bad address, to completely 842438032Speter suppress the sending of the message. This changes 842538032Speter handling of EF_FATALERRS somewhat, and adds an 842638032Speter EF_GLOBALERRS flag. This also fixes a potential problem 842738032Speter with duplicate error messages if there is a syntax error 842838032Speter in the header of a message that isn't noticed until late 842938032Speter in processing. Original problem pointed out by Josh Smith 843038032Speter of Harvey Mudd College. This release includes quite a bit 843138032Speter of dickering with error handling (see below). 843238032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 843338032Speter will only hurt already-broken software and should help 843438032Speter humans. 843538032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 843638032Speter compiled in. It would never read the alias file. 843738032Speter Repair unbalanced `)' and `>' (the "open" versions are already 843838032Speter repaired). 843938032Speter Logging of "done" in dropenvelope() was incorrect: it would 844038032Speter log this even when the queue file still existed. Change 844138032Speter this to only log "done" (at log level 11) when the 844238032Speter queue file is actually removed. From John Myers. 844338032Speter Log "lost connection" in server SMTP at log level 20 if there 844438032Speter is no pending transaction. Some senders just close the 844538032Speter connection rather than sending QUIT. 844638032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 844738032Speter domains that do not have MX records -- this would cause 844838032Speter the subsequent host name lookup to fail. The problem 844938032Speter only occurred if you had FEATURE(nocanonify) set. 845038032Speter Problem noted by Rick McCarty of Texas Instruments. 845138032Speter Fix invocation of setvbuf when passed a -X flag -- I had 845238032Speter unwittingly used an ANSI C extension, and this caused 845338032Speter core dumps on some machines. 845438032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 845538032Speter Previously it just gave an empty send queue, which 845638032Speter then gave either "Need RCPT (recipient)" at the DATA 845738032Speter (confusing, since you had given an RCPT command which 845838032Speter returned 250) or just dropped the email, depending on 845938032Speter whether you were running VERBose mode. Now it usually 846038032Speter diagnoses this case as "aliasing/forwarding loop broken". 846138032Speter Unfortunately, it still doesn't adequately diagnose 846238032Speter some true error conditions. 846338032Speter Add internal concept of "warning messages" using 6xx codes. 846438032Speter These are not reported only to Postmaster. Unbalanced 846538032Speter parens, brackets, and quotes are printed as 653 codes. 846638032Speter They are always mapped to 5xx codes before use in SMTP. 846738032Speter Clean up error messages to tell both the actual address that 846838032Speter failed and the alias they arose from. This makes it 846938032Speter somewhat easier to diagnose problems. Difficulty noted 847038032Speter by Motonori Nakamura. 847138032Speter Fix a problem that inappropriately added a ctladdr to addresses 847238032Speter that shouldn't have had one during a queue run. This 847338032Speter caused error messages to be handled differently during 847438032Speter a queue run than a direct run. 847538032Speter Don't print the qf name and line number if you get errors during 847638032Speter the direct run of the queue from srvrsmtp -- this was 847738032Speter just extra stuff for users to crawl through. 847838032Speter Put command line flags on second line of pid file so you can 847938032Speter auto-restart the daemon with all appropriate arguments. 848038032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 848138032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 848238032Speter restart it. 848338032Speter Remove the ``setuid(getuid())'' in main -- this caused the 848438032Speter IDENT daemon to screw up. This required that I change 848538032Speter HASSETEUID to HASSETREUID and complicate the mode 848638032Speter changing somewhat because both Ultrix and SunOS seem 848738032Speter to have a bug causing seteuid() to set the saved uid 848838032Speter as well as the effective. The program test/t_setreuid.c 848938032Speter will test to see if your implementation of setreuid(2) 849038032Speter is appropriately functional. 849138032Speter The FallBackMX (option V) handling failed to properly identify 849238032Speter fallback to yourself -- most of the code was there, 849338032Speter but it wasn't being enabled. Problem noted by Murray 849438032Speter Kucherawy of the University of Waterloo. 849538032Speter Change :include: open timeout from ETIMEDOUT to an internal 849638032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 849738032Speter with CurHostName" in error messages, which can be 849838032Speter confusing. Reported by Jonathan Kamens of OpenVision 849938032Speter Technologies. 850038032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 850138032Speter process group id. The original fix was to get around 850238032Speter some problems with recalcitrant MUAs, but it breaks 850338032Speter any call from a shell that creates a process group id 850438032Speter different from the process id. I could try to fix 850538032Speter this by diddling the tty owner (using tcsetpgrp or 850638032Speter equivalent) but this is too likely to break other 850738032Speter things. 850838032Speter Portability changes: 850938032Speter Support -M as equivalent to -oM on Ultrix -- apparently 851038032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 851138032Speter instead of using standard flags. Oh joy. This 851243730Speter behavior reported by Jon Giltner of University 851338032Speter of Colorado. 851438032Speter SGI IRIX -- this includes several changes that should 851538032Speter help other strict ANSI compilers. 851638032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 851738032Speter Corporation. 851838032Speter Solaris running the Sun C compiler (which despite the 851938032Speter documentation apparently doesn't define 852038032Speter __STDC__ by default). 852138032Speter ConvexOS from Eric Schnoebelen of Convex. 852238032Speter Sony NEWS workstations and Omron LUNA workstations from 852338032Speter Motonori Nakamura. 852438032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 852538032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 852638032Speter several people have made a good argument that this 852738032Speter creates more problems than it solves (although this 852838032Speter may prove painful in the short run). 852938032Speter CONFIG: generalize all the relays to accept a "mailer:host" 853038032Speter format. 853138032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 853238032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 853338032Speter addresses are also passed through this ruleset. 853438032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 853538032Speter internet-style addresses would "fall off the end" of 853638032Speter ruleset zero and be interpreted as local -- however, 853738032Speter the angle brackets confused the recursive call. 853838032Speter These are now diagnosed as "Unrecognized host name". 853938032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 854038032Speter ifdef(`_MAILER_USENET_') instead of 854138032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 854238032Speter of SINTEF RUNIT, Oslo. 854338032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 854438032Speter early in ruleset 0; this allows .mc authors to bypass 854538032Speter things like the "short circuit" code for local addresses. 854638032Speter Prompted by a comment by Bill Wisner of The Well. 854738032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 854838032Speter esmtp) to send SMTP mail. This allows you to default 854938032Speter to esmtp but use a mailertable or other override to 855038032Speter deal with broken servers. This logic was pointed out 855138032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 855238032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 855338032Speter environments. Ugly as sin. 855438032Speter 855564562Sgshapiro8.3/8.3 1993/07/13 855638032Speter Fix setuid problems introduced in 8.2 that caused messages 855738032Speter like "Cannot create qfXXXXXX: Invalid argument" 855838032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 855938032Speter involved a new compile flag "HASSETEUID" that takes 856038032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 856138032Speter that the POSIX interface is broken enough to break 856238032Speter some systems badly. This includes some fixes for 856338032Speter HP-UX. Also fixes problems where the real uid is 856438032Speter not reset properly on startup (from Neil Rickert). 856538032Speter Fix a problem that caused timed out messages to not report the 856638032Speter addresses that timed out. Error messages are also more 856738032Speter "user friendly". 856838032Speter Drop required bandwidth on connections from 64 bytes/sec to 856938032Speter 16 bytes/sec. 857038032Speter Further Solaris portability changes -- doesn't require the BSD 857138032Speter compatibility library. This also adds a new 857238032Speter "HASGETDTABLESIZE" compile flag which can be used if 857338032Speter you want to use getdtablesize(2) instead of sysconf(2). 857438032Speter These are loosely based on changes from David Meyer at 857538032Speter University of Oregon. This now seems to work, at least 857638032Speter for quick test cases. 857738032Speter Fix a problem that can cause duplicate error messages to be 857838032Speter sent if you are in SMTP, you send to multiple addresses, 857938032Speter and at least one of those addresses is good and points 858038032Speter to an account that has a .forward file (whew!). 858138032Speter Fix a problem causing messages to be discarded if checkcompat() 858238032Speter returned EX_TEMPFAIL (because it didn't properly mark 858338032Speter the "to" address). Problem noted by John Myers. 858438032Speter Fix dfopen to return NULL if the open failed; I was depending 858538032Speter on fdopen(-1) returning NULL, which isn't the case. This 858638032Speter isn't serious, but does result in weird error diagnoses. 858738032Speter From Michael Corrigan. 858838032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 858938032Speter messages sent through UUCP-family mailers. Suggested 859038032Speter by Bill Wisner of The Well. 859138032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 859238032Speter include a "uucp-dom" mailer that uses domain-style 859338032Speter addressing. Suggested by Bill Wisner. 859438032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 859538032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 859638032Speter Christophe Wolfhugel. 859738032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 859838032Speter 859964562Sgshapiro8.2/8.2 1993/07/11 860038032Speter Don't drop out on config file parse errors in -bt mode. 860138032Speter On older configuration files, assume option "l" (use Errors-To 860238032Speter header) for back compatibility. NOTE: this DOES NOT 860338032Speter imply an endorsement of the Errors-To: header in any way. 860438032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 860538032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 860638032Speter SMTP server to give an error on this command, and 860738032Speter logging it in the transcript can be confusing. Fix 860838032Speter from Bill Wisner. 860938032Speter IRIX compatibility changes provided by Dan Rich 861038032Speter <drich@sandman.lerc.nasa.gov>. 861138032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 861238032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 861338032Speter <juo@klinzhai.rutgers.edu> 861438032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 861538032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 861638032Speter match the other flags in that file. 861738032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 861838032Speter Save h_errno in mci struct and improve error message display. 861938032Speter Changes from Eric Wassenaar. 862038032Speter Open /dev/null for the transcript if the create of the xf file 862138032Speter failed; this avoids at least one possible null pointer 862238032Speter reference in very weird cases. From Eric Wassenaar. 862338032Speter Clean up statistics gathering; it was over-reporting because of 862438032Speter forks. From Eric Wassenaar. 862538032Speter Fix problem that causes old Return-Path: line to override new 862638032Speter Return-Path: line (conf.c needs H_FORCE to avoid 862738032Speter re-using old value). From Motonori Nakamura. 862838032Speter Fix broken -m flag in K definition -- even if -m (match only) 862938032Speter was specified, it would still replace the key with the 863038032Speter value. Noted by Rick McCarty of Texas Instruments. 863138032Speter If the name server timed out over several days, no "timed out" 863238032Speter message would ever be sent back. The timeout code 863338032Speter has been moved from markfailure() to dropenvelope() 863438032Speter so that all such failures should be diagnosed. Pointed 863538032Speter out by Christophe Wolfhugel and others. 863638032Speter Relax safefile() constraints: directories in an include or 863738032Speter forward path must be readable by self if the controlling 863838032Speter user owns the entry, readable by all otherwise (e.g., 863938032Speter when reading your .forward file, you have to own and 864038032Speter have X permission in it; everyone needs X permission in 864138032Speter the root and directories leading up to your home); 864238032Speter include files must be readable by anyone, but need not 864338032Speter be owned by you. 864438032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 864538032Speter reading a .forward file; this gets around some problems 864638032Speter on NFS mounts if root permission is not exported and 864738032Speter the user's home directory isn't x'able. 864838032Speter Additional NeXT portability enhancements from Axel Zinser. 864938032Speter Additional HP-UX portability enhancements from Brian Bullen. 865038032Speter Add a timeout around SMTP message writes; this assumes you can 865138032Speter get throughput of at least 64 bytes/second. Note that 865238032Speter this does not impact the "datafinal" default, which 865338032Speter is separate; this is just intended to work around 865438032Speter network clogs that will occur before the final dot 865538032Speter is sent. From Eric Wassenaar. 865638032Speter Change map code to set the "include null" flag adaptively -- 865738032Speter it initially tries both, but if it finds anything 865838032Speter matching without a null it never tries again with a 865938032Speter null and vice versa. If -N is specified, it never 866038032Speter tries without the null and creates new maps with a 866138032Speter null byte. If -O is specified, it never tries with 866238032Speter the null (for efficiency). If -N and -O are specified, 866338032Speter you get -NO (get it?) lookup at all, so this would 866438032Speter be a bad idea. If you don't specify either -N or -O, 866538032Speter it adapts. 866638032Speter Fix recognition of "same from address" so that MH submissions 866738032Speter will insert the appropriate full name information; 866838032Speter this used to work and got broken somewhere along the 866938032Speter way. 867038032Speter Some changes to eliminate some unnecessary SYSERRs in the 867138032Speter log. For example, if you lost a connection, don't 867238032Speter bother reporting that fact on the connection you lost. 867338032Speter Add some "extended debugging" flags to try to track down 867438032Speter why we get occasional problems with file descriptor 867538032Speter one being closed when execing a mailer; it seems to 867638032Speter only happen when there has been another error in the 867738032Speter same transaction. This requires XDEBUG, defined 867838032Speter by default in conf.h. 867938032Speter Add "-X filename" command line flag, which logs both sides of 868038032Speter all SMTP transactions. This is intended ONLY for 868138032Speter debugging bad implementations of other mailers; start 868238032Speter it up, send a message from a mailer that is failing, 868338032Speter and then kill it off and examine the indicated log. 868438032Speter This output is not intended to be particularly human 868538032Speter readable. This also adds the HASSETVBUF compile 868638032Speter flag, defaulted on if your compiler defines __STDC__. 868738032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 868838032Speter have a local net that should get direct connects, you 868938032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 869038032Speter See cf/README for an example. 869138032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 869238032Speter sites that don't use the -d flag. 869338032Speter CONFIG: hide recipient addresses as well as sender addresses 869438032Speter behind $M if FEATURE(allmasquerade) is specified; this 869538032Speter has been requested by several people, but can break 869638032Speter local aliases. For example, if you mail to "localalias" 869738032Speter this will be rewritten as "localalias@masqueradehost"; 869838032Speter although initial delivery will work, replies will be 869938032Speter broken. Use it sparingly. 870038032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 870138032Speter to qualified domains in headers. I believe this is 870238032Speter largely equivalent to the IDA feature of the same name. 870338032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 870438032Speter to override the "system name" as your UUCP name -- 870538032Speter in particular, to use domain-ized UUCP names. From 870638032Speter Bill Wisner of The Well. 870738032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 870838032Speter first. This is currently unused in the config files, 870938032Speter but could be used in a mailertable entry. 871038032Speter 871164562Sgshapiro8.1C/8.1B 1993/06/27 871238032Speter Serious security bug fix: it was possible to read any file on 871338032Speter the system, regardless of ownership and permissions. 871438032Speter If a subroutine returns a fully qualified address, return it 871538032Speter immediately instead of feeding it back into rewriting. 871638032Speter This fixes a problem with mailertable lookups. 871738032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 871838032Speter 871964562Sgshapiro8.1B/8.1A 1993/06/12 872038032Speter Serious bug fix: pattern matching backup algorithm stepped by 872138032Speter two tokens in classes instead of one. Found by Claus 872238032Speter Assmann at University of Kiel, Germany. 872338032Speter 872464562Sgshapiro8.1A/8.1A 1993/06/08 872538032Speter Another mailertable fix.... 872638032Speter 872764562Sgshapiro8.1/8.1 1993/06/07 872838032Speter 4.4BSD freeze.
