Problem noted by Todd C. Miller of 17102528Sgshapiro Courtesan Consulting. 18102528Sgshapiro Make sure that an envelope is queued in the selected queue group 19102528Sgshapiro even if some recipients are deleted or invalid. Problem 20102528Sgshapiro found by Chris Adams of HiWAAY Informations Services. 21102528Sgshapiro Do not send a bounce message if a message is completely collected 22102528Sgshapiro from the SMTP client. Problem noted by Kari Hurtta of the 23102528Sgshapiro Finnish Meteorological Institute. 24102528Sgshapiro Provide an 'install-submit-st' target for sendmail/Makefile to 25102528Sgshapiro install the MSP statistics file using the file named in the 26102528Sgshapiro confMSP_STFILE devtools variable. Requested by Jeff 27102528Sgshapiro Earickson of Colby College. 28102528Sgshapiro Queue up mail with a temporary error if setusercontext() fails 29102528Sgshapiro during a delivery attempt. Patch from Todd C. Miller of 30102528Sgshapiro Courtesan Consulting. 31102528Sgshapiro Fix handling of base64 encoded client authentication data for 32102528Sgshapiro SMTP AUTH. Patch from Elena Slobodnik of life medien GmbH. 33102528Sgshapiro Set the OpenLDAP option LDAP_OPT_RESTART so the client libraries 34102528Sgshapiro restart interrupted system calls. Problem noted by Luiz 35102528Sgshapiro Henrique Duma of BSIOne. 36102528Sgshapiro Prevent a segmentation fault if a program passed a NULL envp using 37102528Sgshapiro execve(). 38102528Sgshapiro Document a problem with the counting of queue runners that may 39102528Sgshapiro cause delays if MaxQueueChildren is set too low. Problem 40102528Sgshapiro noted by Ian Duplisse of Cable Television Laboratories, Inc. 41102528Sgshapiro If discarding a message based on a recipient, don't try to look up 42102528Sgshapiro the recipient in the mailbox database if F=w is set. This 43102528Sgshapiro allows users to discard bogus recipients when dealing with 44102528Sgshapiro spammers without tipping them off. Problem noted by Neil 45102528Sgshapiro Rickert of Northern Illinois University. 46102528Sgshapiro If applying a header check to a header with unstructured data, 47102528Sgshapiro e.g., Subject:, then do not run syntax checks that are 48102528Sgshapiro supposed for addresses on the header content. 49102528Sgshapiro Count messages rejected/discarded via the check_data ruleset. 50102528Sgshapiro Portability: 51102528Sgshapiro Fix compilation on systems which do not allow simple 52102528Sgshapiro copying of the variable argument va_list. Based on 53102528Sgshapiro fix from Scott Walters. 54102528Sgshapiro Fix NSD map open bug. From Michel Bourget of SGI. 55102528Sgshapiro Add some additional IRIX shells to the default shell 56102528Sgshapiro list. From Michel Bourget of SGI. 57102528Sgshapiro Fix compilation issues on Mac OS X 10.2 (Darwin 6.0). 58102528Sgshapiro NETISO support has been dropped. 59102528Sgshapiro CONFIG: There was a seemingly minor change in 8.12.4 with respect 60102528Sgshapiro to handling entries of IP nets/addresses with RHS REJECT. 61102528Sgshapiro These would be rejected in check_rcpt instead of only 62102528Sgshapiro being activated in check_relay. This change has been made to 63102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 64102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 65102528Sgshapiro record for ..." if delay_checks is enabled. However, this 66102528Sgshapiro modification causes a change of behavior if an IP net/address 67102528Sgshapiro is listed in the access map with REJECT and a host/domain 68102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 69102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 70102528Sgshapiro change was made on request of Neil Rickert of Northern 71102528Sgshapiro Illinois University, the side effect has been found by 72102528Sgshapiro Stefaan Van Hoornick. 73102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 74102528Sgshapiro using the local hostname ($j) or domains in class {P}. 75102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 76102528Sgshapiro University. 77102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 78102528Sgshapiro Fix from Andrzej Filip. 79102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 80102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 81102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 82102528Sgshapiro NULL pointer. Problem noted by Andrey J. Melnikoff. 83102528Sgshapiro LIBMILTER: Protect against more interrupted select() calls. Based 84102528Sgshapiro on patch from Jose Marcio Martins da Cruz of Ecole Nationale 85102528Sgshapiro Superieure des Mines de Paris. 86102528Sgshapiro New Files: 87102528Sgshapiro contrib/etrn.0 88102528Sgshapiro 8998841Sgshapiro8.12.5/8.12.5 2002/06/25 9098841Sgshapiro SECURITY: The DNS map can cause a buffer overflow if the user 9198841Sgshapiro specifies a dns map using TXT records in the configuration 9298841Sgshapiro file and a rogue DNS server is queried. None of the 9398841Sgshapiro sendmail supplied configuration files use this option hence 9498841Sgshapiro they are not vulnerable. Problem noted independently by 9598841Sgshapiro Joost Pol of PINE Internet and Anton Rang of Sun Microsystems. 9698841Sgshapiro Unprintable characters in responses from DNS servers for the DNS 9798841Sgshapiro map type are changed to 'X' to avoid potential problems 9898841Sgshapiro with rogue DNS servers. 9998841Sgshapiro Require a suboption when setting the Milter option. Problem noted 10098841Sgshapiro by Bryan Costales. 10198841Sgshapiro Do not silently overwrite command line settings for 10298841Sgshapiro DirectSubmissionModifiers. Problem noted by Bryan 10398841Sgshapiro Costales. 10498841Sgshapiro Prevent a segmentation fault when clearing the event list by 10598841Sgshapiro turning off alarms before checking if event list is 10698841Sgshapiro empty. Problem noted by Allan E Johannesen of Worcester 10798841Sgshapiro Polytechnic Institute. 10898841Sgshapiro Close a potential race condition in transitioning a memory buffered 10998841Sgshapiro file onto disk. From Janani Devarajan of Sun Microsystems. 11098841Sgshapiro Portability: 11198841Sgshapiro Include paths.h on Linux systems running glibc 2.0 or later 11298841Sgshapiro to get the definition for _PATH_SENDMAIL, used by 11398841Sgshapiro rmail and vacation. Problem noted by Kevin 11498841Sgshapiro A. McGrail of Peregrine Hardware. 11598841Sgshapiro NOTE: Linux appears to have broken flock() again. Unless 11698841Sgshapiro the bug is fixed before sendmail 8.13 is shipped, 11798841Sgshapiro 8.13 will change the default locking method to 11898841Sgshapiro fcntl() for Linux kernel 2.4 and later. You may 11998841Sgshapiro want to do this in 8.12 by compiling with 12098841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 12198841Sgshapiro related programs to match locking techniques. 12298841Sgshapiro 12398121Sgshapiro8.12.4/8.12.4 2002/06/03 12498121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 12598121Sgshapiro can leave systems open to a local denial of service 12698121Sgshapiro attack. Be sure to read the "FILE AND MAP PERMISSIONS" 12798121Sgshapiro section of the top level README for more information. 12898121Sgshapiro Problem noted by lumpy. 12998121Sgshapiro Use TempFileMode (defaults to 0600) for the permissions of PidFile 13098121Sgshapiro instead of 0644. 13198121Sgshapiro Change the default file permissions for new alias database files 13298121Sgshapiro from 0644 to 0640. This can be overridden at compile time 13398121Sgshapiro by setting the DBMMODE macro. 13498121Sgshapiro Fix a potential core dump problem if the environment variable 13598121Sgshapiro NAME is set. Problem noted by Beth A. Chaney of 13698121Sgshapiro Purdue University. 13798121Sgshapiro Expand macros before passing them to libmilter. Problem noted 13898121Sgshapiro by Jose Marcio Martins da Cruz of Ecole Nationale 13998121Sgshapiro Superieure des Mines de Paris. 14098121Sgshapiro Rewind the df (message body) before truncating it when libmilter 14198121Sgshapiro replaces the body of a message. Problem noted by Gisle Aas 14298121Sgshapiro of Active State. 14398121Sgshapiro Change SMTP reply code for AUTH failure from 500 to 535 and the 14498121Sgshapiro initial zero-length response to "=" per RFC 2554. Patches 14598121Sgshapiro from Kenneth Murchison of Oceana Matrix Ltd. 14698121Sgshapiro Do not try to fix broken message/rfc822 MIME attachments by 14798121Sgshapiro inserting a MIME-Version: header when MaxMimeHeaderLength 14898121Sgshapiro is set and no 8 to 7 bit conversion is needed. Based on 14998121Sgshapiro patch from Rehor Petr of ICZ (Czech Republic). 15098121Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" if the connection 15198121Sgshapiro is rejected anyway. Noted by Chris Loelke. 15298121Sgshapiro Mention the submission mail queue in the mailq man page. Requested 15398121Sgshapiro by Bill Fenner of AT&T. 15498121Sgshapiro Set ${msg_size} macro when reading a message from the command line 15598121Sgshapiro or the queue. 15698121Sgshapiro Detach from shared memory before dropping privileges back to 15798121Sgshapiro user who started sendmail. 15898121Sgshapiro If AllowBogusHELO is set to false (default) then also complain if 15998121Sgshapiro the argument to HELO/EHLO contains white space. Suggested 16098121Sgshapiro by Seva Gluschenko of Cronyx Plus. 16198121Sgshapiro Allow symbolicly linked forward files in writable directory paths 16298121Sgshapiro if both ForwardFileInUnsafeDirPath and 16398121Sgshapiro LinkedForwardFileInWritableDir DontBlameSendmail options 16498121Sgshapiro are set. Problem noted by Werner Spirk of 16598121Sgshapiro Leibniz-Rechenzentrum Munich. 16698121Sgshapiro Portability: 16798121Sgshapiro Operating systems that lack the ftruncate() call will not 16898121Sgshapiro be able to use Milter's body replacement feature. 16998121Sgshapiro This only affects Altos, Maxion, and MPE/iX. 17098121Sgshapiro Digital UNIX 5.0 has changed flock() semantics to be 17198121Sgshapiro non-compliant. Problem noted by Martin Mokrejs of 17298121Sgshapiro Charles University in Prague. 17398121Sgshapiro The sparc64 port of FreeBSD 5.0 now supports shared 17498121Sgshapiro memory. 17598121Sgshapiro CONFIG: FEATURE(`preserve_luser_host') needs the macro map. 17698121Sgshapiro Problem noted by Andrzej Filip. 17798121Sgshapiro CONFIG: Using 'local:' as a mailertable value with 17898121Sgshapiro FEATURE(`preserve_luser_host') and LUSER_RELAY caused mail 17998121Sgshapiro to be misaddressed. Problem noted by Andrzej Filip. 18098121Sgshapiro CONFIG: Provide a workaround for DNS based rejection lists that 18198121Sgshapiro fail for AAAA queries. Problem noted by Chris Boyd. 18298121Sgshapiro CONFIG: Accept the machine's hostname as resolvable when checking 18398121Sgshapiro the sender address. This allows locally submitted mail to 18498121Sgshapiro be accepted if the machine isn't connected to a nameserver 18598121Sgshapiro and doesn't have an /etc/hosts entry for itself. Problem 18698121Sgshapiro noted by Robert Watson of the TrustedBSD Project. 18798121Sgshapiro CONFIG: Use deferred expansion for checking the ${deliveryMode} 18898121Sgshapiro macro in case the SMTP VERB command is used. Problem 18998121Sgshapiro noted by Bryan Costales. 19098121Sgshapiro CONFIG: Avoid a duplicate '@domain' virtusertable lookup if no 19198121Sgshapiro matches are found.

Suggested 19398121Sgshapiro by Lou Katz of Metron Computerware, Ltd. 19498121Sgshapiro CONFIG: Add mailer cyrusv2 for Cyrus V2. Contributed by 19598121Sgshapiro Kenneth Murchison of Oceana Matrix Ltd. 19698121Sgshapiro CONTRIB: Fix wording in default dnsblaccess rejection message to 19798121Sgshapiro match dnsbl change. 19898121Sgshapiro DEVTOOLS: Add new option for access mode of statistics file, 19998121Sgshapiro confSTMODE, which specifies the permissions when initially 20098121Sgshapiro installing the sendmail statistics file. 20198121Sgshapiro LIBMILTER: Mark the listening socket as close-on-exec in case 20298121Sgshapiro a user's filter starts other applications. 20398121Sgshapiro LIBSM: Allow the MBDB initialize, lookup, and/or terminate 20498121Sgshapiro functions in SmMbdbTypes to be set to NULL. 20598121Sgshapiro MAKEMAP: Change the default file permissions for new databases from 20698121Sgshapiro 0644 to 0640. This can be overridden at compile time 20798121Sgshapiro by setting the DBMMODE macro. 20898121Sgshapiro SMRSH: Fix man page bug: replace SMRSH_CMDBIN with SMRSH_CMDDIR. 20998121Sgshapiro Problem noted by Dave Alden of Ohio State University. 21098121Sgshapiro VACATION: When listing the vacation database (-l), don't show 21198121Sgshapiro bogus timestamps for excluded (-x) addresses. Problem 21298121Sgshapiro noted by Bryan Costales. 21398121Sgshapiro New Files: 21498121Sgshapiro cf/mailer/cyrusv2.m4 21598121Sgshapiro 21694334Sgshapiro8.12.3/8.12.3 2002/04/05 21794334Sgshapiro NOTICE: In general queue files should not be moved if queue groups 21894334Sgshapiro are used. In previous versions this could cause mail 21994334Sgshapiro not to be delivered if a queue file is repeatedly moved 22094334Sgshapiro by an external process whenever sendmail moved it back 22194334Sgshapiro into the right place. Some precautions have been taken 22294334Sgshapiro to avoid moving queue files if not really necessary. 22394334Sgshapiro sendmail may use links to refer to queue files and it 22494334Sgshapiro may store the path of data files in queue files. Hence 22594334Sgshapiro queue files should not be moved unless those internals 22694334Sgshapiro are understood and the integrity of the files is not 22794334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 22894334Sgshapiro University. 22994334Sgshapiro If an error mail is created, and the mail is split across different 23094334Sgshapiro queue directories, and SuperSafe is off, then write the mail 23194334Sgshapiro to disk before splitting it, otherwise an assertion is 23294334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 23394334Sgshapiro of INTERMETA. 23494334Sgshapiro Fix possible race condition that could cause sendmail to forget 23594334Sgshapiro running queues. Problem noted by Jeff Wasilko of smoe.org. 23694334Sgshapiro Handle bogus qf files better without triggering assertions. 23794334Sgshapiro Problem noted by Guy Feltin. 23894334Sgshapiro Protect against interrupted select() call when enforcing Milter 23994334Sgshapiro read and write timeouts. Patch from Gurusamy Sarathy of 24094334Sgshapiro ActiveState. 24194334Sgshapiro Matching queue IDs with -qI should be case sensitive. Problem 24294334Sgshapiro noted by Anne Bennett of Concordia University. 24394334Sgshapiro If privileges have been dropped, don't try to change group ID to 24494334Sgshapiro the RunAsUser group. Problem noted by Neil Rickert of 24594334Sgshapiro Northern Illinois University. 24694334Sgshapiro Fix SafeFileEnvironment path munging when the specified path 24794334Sgshapiro contains a trailing slash. Based on patch from Dirk Meyer 24894334Sgshapiro of Dinoex. 24994334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 25094334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 25194334Sgshapiro Polytechnic Institute. 25294334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 25394334Sgshapiro if several mails are sent in one session and some of them 25494334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 25594334Sgshapiro Change timeout check such that cached information about a connection 25694334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 25794334Sgshapiro Based on patch from David Burns of Portland State University. 25894334Sgshapiro Properly count message size for mailstats during mail collection. 25994334Sgshapiro Problem noted by Werner Wiethege. 26094334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 26194334Sgshapiro patch from by Motonori Nakamura of Kyoto University. 26294334Sgshapiro Provide workaround for getopt() implementations that do not catch 26394334Sgshapiro missing arguments. 26494334Sgshapiro Fix the message size calculation if the message body is replaced by 26594334Sgshapiro a milter filter and buffered file I/O is being used. 26694334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 26794334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 26894334Sgshapiro Problem noted by Werner Wiethege. 26994334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 27094334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 27194334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 27294334Sgshapiro Properly deal with a case where sendmail is called by root running 27394334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 27494334Sgshapiro Lusky of ISS Atlanta. 27594334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 27694334Sgshapiro directories are used and mail is sent to a mailing list 27794334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 27894334Sgshapiro of Concordia University. 27994334Sgshapiro Fix class map parsing code if optional key is specified. Problem 28094334Sgshapiro found by Mario Nigrovic. 28194334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 28294334Sgshapiro incoming messages. A leading dot is always stripped by the 28394334Sgshapiro SMTP receiver regardless of whether or not it is followed by 28494334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 28594334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 28694334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 28794334Sgshapiro Elvers. 28894334Sgshapiro Correct the statistics gathered for total number of connections. 28994334Sgshapiro Instead of being the exact same number as the total number 29094334Sgshapiro of messages (T line in mailstats) it now represents the 29194334Sgshapiro total number of TCP connections. 29294334Sgshapiro Be more explicit about syntax errors in addresses, especially 29394334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 29494334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 29594334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 29694334Sgshapiro are used. Problem noted by Suresh Ramasubramanian. 29794334Sgshapiro Prevent a race condition on child cleanup for delivery to files. 29894334Sgshapiro Problem noted by Fletcher Mattox of the University of 29994334Sgshapiro Texas. 30094334Sgshapiro Change the SMTP error code for temporary map failures from 421 30194334Sgshapiro to 451. 30294334Sgshapiro Do not assume that realloc(NULL, size) works on all OS (this was 30394334Sgshapiro only done in one place: queue group creation). Based on 30494334Sgshapiro patch by Bryan Costales. 30594334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 30694334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 30794334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 30894334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 30994334Sgshapiro errors. By doing so, the host was marked as having a 31094334Sgshapiro temporary problem and other mail destined for that host was 31194334Sgshapiro queued for the next queue run. Problem noted by Fletcher 31294334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 31394334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 31494334Sgshapiro and Neil Rickert of Northern Illinois University. 31594334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 31694334Sgshapiro which drop the connection instead of responding to the 31794334Sgshapiro command). 31894334Sgshapiro Portability: 31994334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 32098121Sgshapiro available. 32194334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 32294334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 32394334Sgshapiro settings. Patch from Elias Halldor Agustsson of 32494334Sgshapiro Skyrr. 32594334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 32694334Sgshapiro noted by John Beck. 32794334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 32894334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 32994334Sgshapiro Rajesh Somasund of Hewlett-Packard. 33094334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 33194334Sgshapiro SMTP AUTH information. This feature was actually added in 33294334Sgshapiro 8.12.0 but a release note was not included. 33394334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 33494334Sgshapiro parameter is set and the LDAP lookup returns a temporary 33594334Sgshapiro error. 33694334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 33794334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 33894334Sgshapiro Krzysztof Oledzki. 33994334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 34094334Sgshapiro initialization as aliases are not needed for the MSP. 34194334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 34294334Sgshapiro is in use. Patch from Andrzej Filip. 34394334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 34494334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 34594334Sgshapiro This will only have an effect if a parameter is specified, 34694334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 34794334Sgshapiro it is embedded in square brackets. Problem noted by 34894334Sgshapiro Theo Van Dinter of Collective Technologies. 34994334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 35094334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 35194334Sgshapiro to allow for the proper time zone on systems where the 35294334Sgshapiro default results in misleading time stamps. That is, syslog 35394334Sgshapiro time stamps and Date headers on submitted mail will use the 35494334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 35594334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 35694334Sgshapiro by Neil Rickert of Northern Illinois University. 35794334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 35894334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 35994334Sgshapiro noted by John Beck. 36094334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 36194334Sgshapiro if queue groups are used. 36294334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 36394334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 36494334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 36594334Sgshapiro Suggested by Bryan Costales. 36694334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 36794334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 36894334Sgshapiro structure that is passed to xxfi_connect(). Notice: 36998121Sgshapiro this fix requires that sendmail and libmilter both have 37098121Sgshapiro this change; mixing versions may lead to wrong port 37194334Sgshapiro values depending on the endianness of the involved systems. 37294334Sgshapiro Problem noted by Gisle Aas of ActiveState. 37394334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 37494334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 37594334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 37694334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 37794334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 37894334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 37994334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 38094334Sgshapiro this to 1 if your LDAP client libraries include 38194334Sgshapiro ldap_memfree(). 38294334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 38394334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 38494334Sgshapiro SMRSH: Fix compilation problem on some operating systems. Problem 38594334Sgshapiro noted by Christian Krackowizer of schuler technodat GmbH. 38694334Sgshapiro VACATION: Allow root to operate on user vacation databases. Based 38794334Sgshapiro on patch from Greg Couch of the University of California, 38894334Sgshapiro San Francisco. 38994334Sgshapiro VACATION: Don't ignore -C option. Based on patch by Bryan Costales. 39094334Sgshapiro VACATION: Clarify option usage in the man page. Problem noted by 39194334Sgshapiro Joe Barbish. 39294334Sgshapiro New Files: 39394334Sgshapiro libmilter/docs/smfi_setbacklog.html 39494334Sgshapiro 39590792Sgshapiro8.12.2/8.12.2 2002/01/13 39690792Sgshapiro Don't complain too much if stdin, stdout, or stderr are missing 39790792Sgshapiro at startup, only log an error message. 39890792Sgshapiro Fix potential problem if an unknown operation mode (character 39990792Sgshapiro following -b) has been specified. 40090792Sgshapiro Prevent purgestat from looping even if someone changes the 40190792Sgshapiro permissions or owner of hoststatus files. Problem noted 40290792Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 40390792Sgshapiro Properly record dropped connections in persistent host status. 40490792Sgshapiro Problem noted by Ulrich Windl of the Universitat 40590792Sgshapiro Regensburg. 40690792Sgshapiro Remove newlines from recipients read via sendmail -t to prevent 40790792Sgshapiro SMTP protocol errors when sending the RCPT command. 40890792Sgshapiro Problem noted by William D. Colburn of the New Mexico 40990792Sgshapiro Institute of Mining and Technology. 41090792Sgshapiro Only log milter body replacements once instead of for each body 41190792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 41290792Sgshapiro the Finnish Meteorological Institute. 41390792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 41490792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 41590792Sgshapiro of the Finnish Meteorological Institute. 41690792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 41790792Sgshapiro needs to collect children status to avoid zombie processes. 41890792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 41990792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 42090792Sgshapiro commands are issued. This makes it consistent with normal 42190792Sgshapiro SMTP connections. 42290792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 42390792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 42490792Sgshapiro and Technology. 42590792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 42690792Sgshapiro message sender if the sender had used a deprecated RFC822 42790792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 42890792Sgshapiro Meteorological Institute. 42990792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 43090792Sgshapiro parsing. Problem noted by Jorg Bielak from Coastal Web 43190792Sgshapiro Online. 43290792Sgshapiro For systems on which stat(2) does not return a value for st_blksize 43390792Sgshapiro that is the "optimal blocksize for I/O" three new compile 43490792Sgshapiro time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF, 43590792Sgshapiro and SM_IO_MAX_BUF, which define an upper limit for 43690792Sgshapiro regular files, and a lower and upper limit for other file 43790792Sgshapiro types, respectively. 43890792Sgshapiro Fix a potential deadlock if two events are supposed to occur at 43990792Sgshapiro exactly the same time. Problem noted by Valdis Kletnieks 44090792Sgshapiro of Virginia Tech. 44190792Sgshapiro Perform envelope splitting for aliases listed directly in the 44290792Sgshapiro alias file, not just for include/.forward files. 44390792Sgshapiro Problem noted by John Beck of Sun Microsystems. 44490792Sgshapiro Allow selection of queue group for mailq using -qGgroup. 44590792Sgshapiro Based on patch by John Beck of Sun Microsystems. 44690792Sgshapiro Make sure cached LDAP connections used my multiple maps in the same 44790792Sgshapiro process are closed. Patch from Taso N. Devetzis. 44890792Sgshapiro If running as root, allow reading of class files in protected 44990792Sgshapiro directories. Patch from Alexander Talos of the University 45090792Sgshapiro of Vienna. 45190792Sgshapiro Correct a few LDAP related memory leaks. Patch from David Powell 45290792Sgshapiro of Sun Microsystems. 45390792Sgshapiro Allow specification of an empty realm via the authinfo ruleset. 45490792Sgshapiro This is necessary to interoperate as an SMTP AUTH client 45590792Sgshapiro with servers that do not support realms when using 45690792Sgshapiro CRAM-MD5. Problem noted by Bjoern Voigt of TU Berlin. 45790792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 45890792Sgshapiro server gets stuck while processing that command. Problem 45990792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 46090792Sgshapiro In addition to printing errors when parsing recipients during 46190792Sgshapiro command line invocations log them to make it simpler 46290792Sgshapiro to understand possible DSNs to postmaster. 46390792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 46490792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 46590792Sgshapiro instead of forcing localhost. 46690792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 46790792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 46890792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 46990792Sgshapiro noted by Neil Rickert of Northern Illinois University. 47090792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 47190792Sgshapiro dropping the connection during an SMTP transaction, stop 47290792Sgshapiro sending commands. This prevents bogus "Bad file number" 47390792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 47490792Sgshapiro Worcester Polytechnic Institute. 47590792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 47690792Sgshapiro almost always too small; do not guess the size at all. 47790792Sgshapiro New VENDOR_DEC for Compaq/DEC. Requested by James Seagraves of 47890792Sgshapiro Compaq Computer Corp. 47990792Sgshapiro Fix DaemonPortOptions IPv6 address parsing such that ::1 works 48090792Sgshapiro properly.

Add configuration options for 55490792Sgshapiro different set*gid() calls to reset saved gid. Problem 55590792Sgshapiro found by Michal Zalewski. 55690792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 55790792Sgshapiro privileges by disabling debugging (command line -d flag) 55890792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 55990792Sgshapiro used. Suggested by Michal Zalewski. 56090792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 56190792Sgshapiro Problem found by Michal Zalewski. 56290792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 56390792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 56490792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 56590792Sgshapiro If debugging is turned on (-d0.10) print not just the default 56690792Sgshapiro values for configuration file and pid file but also the 56790792Sgshapiro selected values. Problem noted by Brad Chapman. 56890792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 56990792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 57090792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 57190792Sgshapiro this only applied to hostname canonification. Problem 57290792Sgshapiro noted by Bill Fenner of AT&T Research. 57390792Sgshapiro Ignore comments in NIS host records when trying to find the 57490792Sgshapiro canonical name for a host. 57590792Sgshapiro When sendmail has extra privileges, limit mail submission command 57690792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 57790792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 57890792Sgshapiro suggestion from Michal Zalewski. 57990792Sgshapiro Portability: 58090792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 58190792Sgshapiro `uname` does not given complete information. 58290792Sgshapiro Problem noted by Keith Neufeld of the Cessna 58390792Sgshapiro Aircraft Company. 58490792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 58590792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 58690792Sgshapiro Avoid compiler warnings by not using pointers to pass 58790792Sgshapiro integers.

Suggested 63490792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 63590792Sgshapiro (IdS). 63690792Sgshapiro Fixed problem of a global variable being used for a timeout jump 63790792Sgshapiro point where the variable could become overused for more than 63890792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 63990792Sgshapiro a corrupted stack causing a core dump. The timeout is now 64090792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 64190792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 64290792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 64390792Sgshapiro checks (group ID of RunAsUser). This allows use of a 64490792Sgshapiro set-group-ID sendmail binary for initial message submission 64590792Sgshapiro and no set-user-ID root sendmail is needed. For details 64690792Sgshapiro see sendmail/SECURITY. 64790792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 64890792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 64990792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 65090792Sgshapiro with a fallback of sendmail.cf as configuration file. See 65190792Sgshapiro sendmail/SECURITY. 65290792Sgshapiro New configuration file option UseMSP to allow group writable queue 65390792Sgshapiro files if the group is the same as that of a set-group-ID 65490792Sgshapiro sendmail binary. See sendmail/SECURITY. 65590792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 65690792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 65790792Sgshapiro is sendmail.cf (to be backward compatible). This selection 65890792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 65990792Sgshapiro file: client or mta). See sendmail/SECURITY. 66090792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 66190792Sgshapiro command has been removed. 66290792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 66390792Sgshapiro at compile time or per host (ruleset). 66490792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 66590792Sgshapiro used to look up local mail recipients; the default value 66690792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 66790792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 66890792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 66990792Sgshapiro long, to accomodate envelope splitting. File systems with 67090792Sgshapiro a 14 character file name length limit are no longer 67190792Sgshapiro supported. 67290792Sgshapiro Recipient list used for delivery now gets internally ordered by 67390792Sgshapiro hostsignature (character string version of MX RR). This orders 67490792Sgshapiro recipients for the same MX RR's together meaning smaller 67590792Sgshapiro portions of the list need to be scanned (instead of the whole 67690792Sgshapiro list) each delivery() pass to determine piggybacking. The 67790792Sgshapiro significance of the change is better the larger the recipient 67890792Sgshapiro list. Hostsignature is now created during recipient list 67990792Sgshapiro creation rather than just before delivery. 68090792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 68190792Sgshapiro piggybacking (called coincidental) extended to coattail 68290792Sgshapiro piggybacking. Rather than complete MX RR matching 68390792Sgshapiro (coincidental) piggybacking is done if just the lowest value 68490792Sgshapiro preference matches (coattail). 68590792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 68690792Sgshapiro try other MX hosts if available. 68790792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 68890792Sgshapiro outgoing (client-side) SMTP Authentication. 68990792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 69090792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 69190792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 69290792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 69390792Sgshapiro A new ruleset authinfo can be used to return client side 69490792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 69590792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 69690792Sgshapiro removed in future versions. 69790792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 69890792Sgshapiro requires 334. Mercury 1.48 is a known offender. 69990792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 70090792Sgshapiro for the security layer in SMTP AUTH (SASL). See 70190792Sgshapiro doc/op/op.me for details. 70290792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 70390792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 70490792Sgshapiro signed the presented certificate, the CN and the MD5 hash 70590792Sgshapiro of the presented certificate, respectively. 70690792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 70790792Sgshapiro New ruleset srv_features to enable/disable certain features in the 70890792Sgshapiro server per connection. See doc/op/op.me for details. 70990792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 71090792Sgshapiro recipient; useful to decide whether a conection is secure 71190792Sgshapiro enough on a per recipient basis. 71290792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 71390792Sgshapiro for STARTTLS. 71490792Sgshapiro If no certificate has been requested, the macro {verify} has the 71590792Sgshapiro value "NOT". 71690792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 71790792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 71890792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 71990792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 72090792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 72190792Sgshapiro really required. This change results in a noticable 72290792Sgshapiro performance gains on most machines. Moreover, if shared 72390792Sgshapiro memory is in use, reuse the key several times. 72490792Sgshapiro Add queue groups which can be used to group queue directories with 72590792Sgshapiro the same behavior together. See doc/op/op.me for details. 72690792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 72790792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 72890792Sgshapiro are initially sorted which may result in faster envelope 72990792Sgshapiro splitting. If the mail is submitted directly from the 73090792Sgshapiro command line, then the value also limits the number of 73190792Sgshapiro processes to deliver the envelopes; if more envelopes are 73290792Sgshapiro created they are only queued up and must be taken care of 73390792Sgshapiro by a queue run. 73490792Sgshapiro The check for 'enough disk space' now pays attention to which file 73590792Sgshapiro system each queue directory resides in. 73690792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 73790792Sgshapiro New option QueueFileMode for the default permissions of queue files. 73890792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 73990792Sgshapiro group (one or more queues in a multi-queue environment 74090792Sgshapiro collected together) to process the same work list at the 74190792Sgshapiro same time. 74290792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 74390792Sgshapiro active queue runner processes. 74490792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 74590792Sgshapiro runners per queue group. 74690792Sgshapiro Queue member selection by substring pattern matching now allows 74790792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 74890792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 74990792Sgshapiro of the queue that match during processing. 75090792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 75190792Sgshapiro periodically forking a child to process the queue, a single 75290792Sgshapiro child is forked for each queue that sleeps between queue 75390792Sgshapiro runs. A SIGHUP signal can be sent to restart this 75490792Sgshapiro persistent queue runner. 75590792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 75690792Sgshapiro sendmail process which only runs the queue at an interval: 75790792Sgshapiro sendmail -q15m). 75890792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 75990792Sgshapiro Proposed by Thom O'Connor. 76090792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 76190792Sgshapiro unless the new -qf option or -v is used. 76290792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 76390792Sgshapiro several queue runners are started by hand to avoid contention. 76490792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 76590792Sgshapiro of the qf file (older entries first). 76690792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 76790792Sgshapiro a client to specify an amount of time within which an e-mail 76890792Sgshapiro should be delivered. New option DeliverByMin added to set the 76990792Sgshapiro minimum amount of time or disable the extension. 77090792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 77190792Sgshapiro not allowed unless escaped or quoted. 77290792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 77390792Sgshapiro by Leif Johansson of Stockholm University, which was based on 77490792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 77590792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 77690792Sgshapiro Technology, Stockholm, Sweden. 77790792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 77890792Sgshapiro behavior (no MX lookups), put the name in square brackets. 77990792Sgshapiro Proposed by Thom O'Connor. 78090792Sgshapiro Use shared memory to store free space of filesystems that are used 78190792Sgshapiro for queues, if shared memory is available and if a key is set 78290792Sgshapiro via SharedMemoryKey. This minimizes the number of system 78390792Sgshapiro calls to check the available space. See doc/op/op.me for 78490792Sgshapiro details. 78590792Sgshapiro If shared memory is compiled in the option -bP can be used to print 78690792Sgshapiro the number of entries in the queue(s). 78790792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 78890792Sgshapiro and the usual documentation for details. 78990792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 79090792Sgshapiro Remove '-U' (initial user submission) command line option as 79190792Sgshapiro announced in 8.10. 79290792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 79390792Sgshapiro New macro {addr_type} which contains whether the current address is 79490792Sgshapiro an envelope sender or recipient address. Suggested by 79590792Sgshapiro Neil Rickert of Northern Illinois University. 79690792Sgshapiro Two new options for host maps: -d (retransmission timeout), 79790792Sgshapiro -r (number of retries). 79890792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 79990792Sgshapiro separator such that a lookup can return both an attribute 80090792Sgshapiro and value separated by the given separator. 80190792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 80290792Sgshapiro to map class arith. 80390792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 80490792Sgshapiro (errors that occur when sending an error message) are dropped. 80590792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 80690792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 80790792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 80890792Sgshapiro requirements for files containing secret keys. This is 80990792Sgshapiro necessary for the MSP if client authentification is used. 81090792Sgshapiro Properly handle quoted filenames for class files (to allow for 81190792Sgshapiro filenames with spaces). 81290792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 81390792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 81490792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 81590792Sgshapiro {if_addr_out} address of interface of outgoing connection. 81690792Sgshapiro {if_family_out} family of interface of outgoing connection. 81790792Sgshapiro The latter two are only set if the interface does not belong 81890792Sgshapiro to the loopback net. 81990792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 82090792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 82190792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 82290792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 82390792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 82490792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 82590792Sgshapiro all connections for a single delivery attempt to succeed. 82690792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 82790792Sgshapiro a threshold number of recipients has been rejected (option 82890792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 82990792Sgshapiro Development Group. 83090792Sgshapiro New option DelayLA to delay connections if the load averages 83190792Sgshapiro exceeds the specified value. The default of 0 does not 83290792Sgshapiro change the previous behavior. A value greater than 0 83390792Sgshapiro will cause sendmail to sleep for one second on most 83490792Sgshapiro SMTP commands and before accepting connections if that 83590792Sgshapiro load average is exceeded. 83690792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 83790792Sgshapiro recipients that are sent during a connection to a mailer. 83890792Sgshapiro This also introduces a new mailer field 'r' which defines 83990792Sgshapiro the maximum number of recipients (defaults to 100). 84090792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 84190792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 84290792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 84390792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 84490792Sgshapiro instead. 84590792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 84690792Sgshapiro builtin mailer pathnames. Use TCP instead. 84790792Sgshapiro PH map code updated to use the new libphclient API instead of the 84890792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 84990792Sgshapiro University of Illinois at Urbana-Champaign. 85090792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 85190792Sgshapiro for direct (command line) submissions. 85290792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 85390792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 85490792Sgshapiro Hagino of the KAME Project. 85590792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 85690792Sgshapiro whose content is rewritten similar to Reply-To:. 85790792Sgshapiro Proposed by Andrzej Filip. 85890792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 85990792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 86090792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 86190792Sgshapiro AUTH/STARTTLS related logfile entries. 86290792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 86390792Sgshapiro before logging. 86490792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 86590792Sgshapiro (at LogLevel 9/10 or higher). 86690792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 86790792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 86890792Sgshapiro in which most commands are rejected due to check_relay or 86990792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 87090792Sgshapiro Change logging format for cloned envelopes to be similar to that for 87190792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 87290792Sgshapiro of the Universitat Regensburg. 87390792Sgshapiro Added libsm, a C library of general purpose abstractions including 87490792Sgshapiro assertions, tracing and debugging with named debug categories, 87590792Sgshapiro exception handling, malloc debugging, resource pools, 87690792Sgshapiro portability abstractions, and an extensible buffered I/O 87790792Sgshapiro package. It will at some point replace libsmutil. 87890792Sgshapiro See libsm/index.html for details. 87990792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 88090792Sgshapiro care of by fork() and exit(). 88190792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 88290792Sgshapiro more consistent portablity amongst different platforms 88390792Sgshapiro new and old (from new libsm). 88490792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 88590792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 88690792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 88790792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 88890792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 88990792Sgshapiro synchronizations calls. 89090792Sgshapiro Add per-recipient status information to mailq -v output. 89190792Sgshapiro T_ANY queries are no longer used by sendmail. 89290792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 89390792Sgshapiro too (see include/sm/cdefs.h for more info). 89490792Sgshapiro sendmail -d now has general support for named debug categories. 89590792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 89690792Sgshapiro for details. 89790792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 89890792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 89990792Sgshapiro generated by this condition were illegal (not RFC conform). 90090792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 90190792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 90290792Sgshapiro mailer and the recipient has hence been rejected during the 90390792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 90490792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 90590792Sgshapiro that do not have postmaster defined. If an email was sent 90690792Sgshapiro from an address to which a DSN cannot be returned and 90790792Sgshapiro in which at least one recipient address is non-deliverable, 90890792Sgshapiro then that email had been delivered in each queue run. 90990792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 91090792Sgshapiro degli Studi dell'Insubria. 91190792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 91290792Sgshapiro i.e., the corresponding code is always compiled in now. 91390792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 91490792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 91590792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 91690792Sgshapiro attempting to canonify a hostname, some broken nameservers 91790792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 91890792Sgshapiro lookups. If you want to excuse this behavior, use this new 91990792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 92090792Sgshapiro Mark Roth of the University of Illinois at 92190792Sgshapiro Urbana-Champaign. 92290792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 92390792Sgshapiro noted by Joy Latten of IBM. 92490792Sgshapiro ConnectionRateThrottle limits the number of connections per second 92590792Sgshapiro to each daemon individually, not the overall number of 92690792Sgshapiro connections. 92790792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 92890792Sgshapiro sendmail to use a default alias schema as outlined in the 92990792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 93090792Sgshapiro cf/README. 93190792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 93290792Sgshapiro the first character after the class name is not a '/' or a 93390792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 93490792Sgshapiro rest of the line will be parsed as a map lookup. This 93590792Sgshapiro allows classes to be filled via a map lookup. See op.me 93690792Sgshapiro for more syntax information. Specifically, this can be 93790792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 93890792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 93990792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 94090792Sgshapiro example). 94190792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 94290792Sgshapiro the default schema used in the above two items. 94390792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 94490792Sgshapiro warning if a program being run from a mailer or file class 94590792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 94690792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 94790792Sgshapiro if a program being run from a mailer or file class 94890792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 94990792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 95090792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 95190792Sgshapiro (without quotes) will disable this and return to the 95290792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 95390792Sgshapiro Suggested by Bryan Stansell of GNAC. 95490792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 95590792Sgshapiro HELO/EHLO commands. 95690792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 95790792Sgshapiro possible protocol family which may be used for outgoing 95890792Sgshapiro connections. Restrictions placed on one family only affect 95990792Sgshapiro outgoing connections on that particular family. Because of 96090792Sgshapiro this change, the ${client_flags} macro is not set until the 96190792Sgshapiro connection is established. Based on patch from Motonori 96290792Sgshapiro Nakamura of Kyoto University. 96390792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 96490792Sgshapiro when the -bv option is given by users who are neither root 96590792Sgshapiro nor the TrustedUser so users can not read private aliases, 96690792Sgshapiro forwards, or :include: files. It also will override the -v 96790792Sgshapiro (verbose) command line option. 96890792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 96990792Sgshapiro address can't be used for the outgoing connection, fall 97090792Sgshapiro back to the settings in ClientPortOptions (if set). 97190792Sgshapiro Problem noted by John Beck of Sun Microsystems. 97290792Sgshapiro New named config file rule check_data for DATA command (input: 97390792Sgshapiro number of recipients). Based on patch from Mark Roth of 97490792Sgshapiro the University of Illinois at Urbana-Champaign. 97590792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 97690792Sgshapiro can be specified using the '#' option character. For 97790792Sgshapiro example, 'ETRN #queuegroup'. 97890792Sgshapiro If an LDAP server times out or becomes unavailable, close the 97990792Sgshapiro current connection and reopen to get to one of the fallback 98090792Sgshapiro servers. Patch from Paul Hilchey of the University of 98190792Sgshapiro British Columbia. 98290792Sgshapiro Make default error number on $#error messages 550 instead of 501 98390792Sgshapiro because 501 is not allowed on all commands. 98490792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 98590792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 98690792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 98790792Sgshapiro if required. 98890792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 98990792Sgshapiro class instead. 99090792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 99190792Sgshapiro "IPv6:" tag to identify the address properly. For example, 99290792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 99390792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 99490792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 99590792Sgshapiro MTA is running. For example, during a queue run. 99690792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 99790792Sgshapiro RES_USE_INET6 resolver option.

Patch from Bryan 100990792Sgshapiro Costales of SL3D, Inc. 101090792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 101190792Sgshapiro ${MyMacro} is defined but also that it is not empty. 101290792Sgshapiro Properly quote usernames with special characters if they are used 101390792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 101490792Sgshapiro Meteorological Institute. 101590792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 101690792Sgshapiro messages for messages for mailing list expanded addresses 101790792Sgshapiro which are not delivered on the initial attempt. 101890792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 101990792Sgshapiro the final dot has been sent to avoid affecting future 102090792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 102190792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 102290792Sgshapiro file systems that require to call fsync() for a directory 102390792Sgshapiro if the meta-data in it has been changed. This should be 102490792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 102590792Sgshapiro See sendmail/README for further information. 102690792Sgshapiro Avoid file locking deadlock when updating the statistics file if 102790792Sgshapiro sendmail is signaled to terminate. Problem noted by 102890792Sgshapiro Christophe Wolfhugel of France Telecom. 102990792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 103090792Sgshapiro envelope is initialized.

This allows handling of details by 106590792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 106690792Sgshapiro introduced to match only non-empty details of addresses. 106790792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 106890792Sgshapiro and hence there is no required order within the MAILER 106990792Sgshapiro section anymore except for MAILER(`uucp') which must come 107090792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 107190792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 107290792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 107390792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 107490792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 107590792Sgshapiro in the access map which returns OK or RELAY actually 107690792Sgshapiro terminates check_* ruleset checking. 107790792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 107890792Sgshapiro tls_rcpt, see cf/README for details. 107990792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 108090792Sgshapiro STARTTLS has been used to "(version=${tls_version} 108190792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 108290792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 108390792Sgshapiro options friends/haters instead of "To:" and enable 108490792Sgshapiro specification of whole domains instead of just users. 108590792Sgshapiro Notice: this change is not backward compatible. 108690792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 108790792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 108890792Sgshapiro cf/README for details. 108990792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 109090792Sgshapiro the access map.

Gumpertz of Computer Problem 110090792Sgshapiro Solving. 110190792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 110290792Sgshapiro options, see doc/op/op.me for details. 110390792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 110490792Sgshapiro the security layer in SMTP AUTH (SASL). 110590792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 110690792Sgshapiro immediately. 110790792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 110890792Sgshapiro allows checking of the return values of the DNS lookups. 110990792Sgshapiro See cf/README for details. 111090792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 111190792Sgshapiro temporary lookup failures. 111290792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 111390792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 111490792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 111590792Sgshapiro memory use. 111690792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 111790792Sgshapiro of the sender and the recipient address delimited by the 111890792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 111990792Sgshapiro in the access map. Based on code contributed by Mathias 112090792Sgshapiro Koerber of Singapore Telecommunications Ltd. 112190792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 112290792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 112390792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 112490792Sgshapiro via LMTP.

New option -D mbdb specifies the 121690792Sgshapiro mailbox database type. 121790792Sgshapiro MAIL.LOCAL: New option "-h filename" which instructs mail.local to 121890792Sgshapiro deliver the mail to the named file in the user's home 121990792Sgshapiro directory instead of the system mail spool area. Based on 122090792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 122190792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 122290792Sgshapiro doesn't truncate the statistics file. 122390792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 122490792Sgshapiro instead of white space. 122590792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 122690792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 122790792Sgshapiro Meteorological Institute. 122890792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 122990792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 123090792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 123190792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 123290792Sgshapiro instead of syslog. 123390792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 123490792Sgshapiro in the password file. The -f and -m options must be used 123590792Sgshapiro to specify the database and message file since there is no 123690792Sgshapiro home directory for the default settings for these options. 123790792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 123890792Sgshapiro local mail recipients; it reads the MailboxDatabase option 123990792Sgshapiro from the sendmail.cf file. New option -C cffile which 124090792Sgshapiro specifies the path of the sendmail.cf file. 124190792Sgshapiro New Directories: 124290792Sgshapiro libmilter/docs 124390792Sgshapiro New Files: 124490792Sgshapiro cf/cf/README 124590792Sgshapiro cf/cf/submit.cf 124690792Sgshapiro cf/cf/submit.mc 124790792Sgshapiro cf/feature/authinfo.m4 124890792Sgshapiro cf/feature/compat_check.m4 124990792Sgshapiro cf/feature/enhdnsbl.m4 125090792Sgshapiro cf/feature/msp.m4 125190792Sgshapiro cf/feature/local_no_masquerade.m4 125290792Sgshapiro cf/feature/lookupdotdomain.m4 125390792Sgshapiro cf/feature/preserve_luser_host.m4 125490792Sgshapiro cf/feature/preserve_local_plus_detail.m4 125590792Sgshapiro cf/feature/queuegroup.m4 125690792Sgshapiro cf/sendmail.schema 125790792Sgshapiro contrib/dnsblaccess.m4 125890792Sgshapiro devtools/M4/UNIX/sm-test.m4 125990792Sgshapiro devtools/OS/OpenUNIX.5.i386 126090792Sgshapiro editmap/* 126190792Sgshapiro include/sm/* 126290792Sgshapiro libsm/* 126390792Sgshapiro libsmutil/cf.c 126490792Sgshapiro libsmutil/err.c 126590792Sgshapiro sendmail/SECURITY 126690792Sgshapiro sendmail/TUNING 126790792Sgshapiro sendmail/bf.c 126890792Sgshapiro sendmail/bf.h 126990792Sgshapiro sendmail/sasl.c 127090792Sgshapiro sendmail/sm_resolve.c 127190792Sgshapiro sendmail/sm_resolve.h 127290792Sgshapiro sendmail/tls.c 127390792Sgshapiro Deleted Files: 127490792Sgshapiro cf/feature/rbl.m4 127590792Sgshapiro cf/ostype/aix2.m4 127690792Sgshapiro devtools/OS/AIX.2 127790792Sgshapiro include/sendmail/cdefs.h 127890792Sgshapiro include/sendmail/errstring.h 127990792Sgshapiro include/sendmail/useful.h 128090792Sgshapiro libsmutil/errstring.c 128190792Sgshapiro sendmail/bf_portable.c 128290792Sgshapiro sendmail/bf_portable.h 128390792Sgshapiro sendmail/bf_torek.c 128490792Sgshapiro sendmail/bf_torek.h 128590792Sgshapiro sendmail/clock.c 128690792Sgshapiro Renamed Files: 128790792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 128890792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 128990792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 129090792Sgshapiro 129182017Sgshapiro8.11.6/8.11.6 2001/08/20 129282017Sgshapiro SECURITY: Fix a possible memory access violation when specifying 129382017Sgshapiro out-of-bounds debug parameters.

If sendmail needs to drop 172064562Sgshapiro these privileges and the operating system doesn't set the 172164562Sgshapiro saved-uid as well, exit with an error. Problem noted by 172264562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 172364562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 172464562Sgshapiro it populates. It is possible that some broken 172564562Sgshapiro implementations of snprintf() exist that do not do this. 172664562Sgshapiro Systems in this category should compile with 172764562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 172864562Sgshapiro system and report broken implementations to 172964562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 173064562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 173164562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 173264562Sgshapiro Implementation influenced by the example programs of 173364562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 173464562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 173564562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 173664562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 173764562Sgshapiro cf/README and doc/op/op.*. 173864562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 173964562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 174064562Sgshapiro ${server_name}, and ${server_addr}. These are documented 174164562Sgshapiro in cf/README and doc/op/op.*. 174264562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 174364562Sgshapiro random data. 174464562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 174564562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 174664562Sgshapiro try to use STARTTLS despite the security problems. 174764562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 174864562Sgshapiro support encryption. Based on code contributed by Tim 174964562Sgshapiro Martin of CMU. 175064562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 175164562Sgshapiro strength factor. 175264562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 175364562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 175464562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 175564562Sgshapiro of CMU. 175664562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 175764562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 175864562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 175964562Sgshapiro Fix the default family selection for DaemonPortOptions. As 176064562Sgshapiro documented, unless a family is specified in a 176164562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 176264562Sgshapiro also the default if no DaemonPortOptions value is set. 176364562Sgshapiro Therefore, IPv6 users should configure additional sockets 176464562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 176564562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 176664562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 176764562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 176864562Sgshapiro the interface information for an outgoing connection. 176964562Sgshapiro Not doing so was creating a mismatch between the socket 177064562Sgshapiro family and address used in subsequent connections if the 177164562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 177264562Sgshapiro by John Beck of Sun Microsystems. 177364562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 177464562Sgshapiro family based on the IP address. ${if_family} is no longer 177564562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 177664562Sgshapiro of Sun Microsystems. 177764562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 177864562Sgshapiro macros for both the incoming interface address/family and 177964562Sgshapiro the outgoing interface address/family. In order for M=b 178064562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 178164562Sgshapiro the incoming information in the queue file for later 178264562Sgshapiro delivery attempts. 178364562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 178464562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 178564562Sgshapiro smoe.org. 178664562Sgshapiro Add more vigilance in checking for putc() errors on output streams 178764562Sgshapiro to protect from a bug in Solaris 2.6's putc().

Problem noted by Ari Heikkinen of Pohjois-Savo 180964562Sgshapiro Polytechnic. 181064562Sgshapiro Under the proper circumstances, failed connections would be recorded 181164562Sgshapiro as "Bad file number" instead of "Connection failed" in the 181264562Sgshapiro queue file and persistent host status. Problem noted by 181364562Sgshapiro Graeme Hewson of Oracle. 181464562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 181564562Sgshapiro within the hoststatus directory (e.g., lost+found). 181664562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 181764562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 181864562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 181964562Sgshapiro If a message data file can't be opened at delivery time, panic and 182064562Sgshapiro abort the attempt instead of delivering a message that 182164562Sgshapiro states "<<< No Message Collected >>>". 182264562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 182364562Sgshapiro restrictive.

This option and 209664562Sgshapiro its use is deprecated and will be removed from a future 209764562Sgshapiro version of sendmail. 209864562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 209964562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 210064562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 210164562Sgshapiro (IdS). 210264562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 210364562Sgshapiro a large number of files. See cf/README for more details. 210464562Sgshapiro The directory structure of the distribution has changed slightly 210564562Sgshapiro for easier code sharing among the programs. 210664562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 210764562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 210864562Sgshapiro which hold the client's authentication credentials, 210964562Sgshapiro the mechanism used for authentication, and the 211064562Sgshapiro authorization identity (i.e., the AUTH= parameter if 211164562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 211264562Sgshapiro On systems which use the Torek stdio library (all of the BSD 211364562Sgshapiro distributions), use memory-buffered files to reduce 211464562Sgshapiro file system overhead by not creating temporary files on 211564562Sgshapiro disk. Contributed by Exactis.com, Inc. 211664562Sgshapiro New option DataFileBufferSize to control the maximum size of a 211764562Sgshapiro memory-buffered data (df) file before a disk-based file is 211864562Sgshapiro used.

Contributed by Exactis.com, Inc. 212264562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 212364562Sgshapiro now listen on several different ports. Use: 212464562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 212564562Sgshapiro to run a Message Submission Agent (MSA); this is turned 212664562Sgshapiro on by default in m4-generated .cf files; it can be turned 212764562Sgshapiro off with FEATURE(`no_default_msa'). 212864562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 212964562Sgshapiro begin using RFC 2476 Message Submission for initial user 213064562Sgshapiro message submission. XUSR may disappear from a future release. 213164562Sgshapiro The new '-G' (relay (gateway) submission) command line option 213264562Sgshapiro indicates that the message being submitted from the command 213364562Sgshapiro line is for relaying, not initial submission. This means 213464562Sgshapiro the message will be rejected if the addresses are not fully 213564562Sgshapiro qualified and no canonicalization will be done. Future 213664562Sgshapiro releases may even reject improperly formed messages. 213764562Sgshapiro The '-U' (initial user submission) command line option is 213864562Sgshapiro deprecated and may be removed from a future release. 213964562Sgshapiro Mail user agents should begin using '-G' to indicate that 214064562Sgshapiro this is a relay submission (the inverse of -U). 214164562Sgshapiro The next release of sendmail will assume that any message submitted 214264562Sgshapiro from the command line is an initial user submission and act 214364562Sgshapiro accordingly. 214464562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 214564562Sgshapiro program or deliver to file as the owner of that file, the 214664562Sgshapiro address is marked as unsafe. This means if RunAsUser is 214764562Sgshapiro set, users won't be able to use programs or delivery to 214864562Sgshapiro files in their .forward files. Administrators can override 214964562Sgshapiro this by setting the DontBlameSendmail option to the new 215064562Sgshapiro setting NonRootSafeAddr. 215164562Sgshapiro Allow group or world writable directories if the sticky bit is set 215264562Sgshapiro on the directory and DontBlameSendmail is set to 215364562Sgshapiro TrustStickyBit.

Requested by many. 215864562Sgshapiro New Timeout.control option to limit the total time spent satisfying 215964562Sgshapiro a control socket request. 216064562Sgshapiro New Timeout.resolver options for controlling BIND resolver 216164562Sgshapiro settings: 216264562Sgshapiro Timeout.resolver.retrans 216364562Sgshapiro Sets the resolver's retransmission time interval (in 216464562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 216564562Sgshapiro and Timeout.resolver.retrans.normal. 216664562Sgshapiro Timeout.resolver.retrans.first 216764562Sgshapiro Sets the resolver's retransmission time interval (in 216864562Sgshapiro seconds) for the first attempt to deliver a message. 216964562Sgshapiro Timeout.resolver.retrans.normal 217064562Sgshapiro Sets the resolver's retransmission time interval (in 217164562Sgshapiro seconds) for all resolver lookups except the first 217264562Sgshapiro delivery attempt. 217364562Sgshapiro Timeout.resolver.retry 217464562Sgshapiro Sets the number of times to retransmit a resolver 217564562Sgshapiro query. Sets both Timeout.resolver.retry.first 217664562Sgshapiro and Timeout.resolver.retry.normal. 217764562Sgshapiro Timeout.resolver.retry.first 217864562Sgshapiro Sets the number of times to retransmit a resolver 217964562Sgshapiro query for the first attempt to deliver a message. 218064562Sgshapiro Timeout.resolver.retry.normal 218164562Sgshapiro Sets the number of times to retransmit a resolver 218264562Sgshapiro query for all resolver lookups except the first 218364562Sgshapiro delivery attempt. 218464562Sgshapiro Contributed by Exactis.com, Inc. 218564562Sgshapiro Support multiple queue directories. To use multiple queues, supply 218664562Sgshapiro a QueueDirectory option value ending with an asterisk. For 218764562Sgshapiro example, /var/spool/mqueue/q* will use all of the 218864562Sgshapiro directories or symbolic links to directories beginning with 218964562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 219064562Sgshapiro mind, the queue directory structure should not be changed 219164562Sgshapiro while sendmail is running. Queue runs create a separate 219264562Sgshapiro process for running each queue unless the verbose flag is 219364562Sgshapiro given on a non-daemon queue run. New items are randomly 219464562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 219564562Sgshapiro Support different directories for qf, df, and xf queue files; if 219664562Sgshapiro subdirectories or symbolic links to directories of those names 219764562Sgshapiro exist in the queue directories, they are used for the 219864562Sgshapiro corresponding queue files. Keep in mind, the queue 219964562Sgshapiro directory structure should not be changed while sendmail is 220064562Sgshapiro running. Proposed by Mathias Koerber of Singapore 220164562Sgshapiro Telecommunications Ltd. 220264562Sgshapiro New queue file naming system which uses a filename guaranteed to be 220364562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 220464562Sgshapiro without fancy file system locking. Queued items can be 220564562Sgshapiro moved between queues easily. Contributed by Exactis.com, 220664562Sgshapiro Inc. 220764562Sgshapiro Messages which are undeliverable due to temporary address failures 220864562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 220964562Sgshapiro set. Contributed by Exactis.com, Inc. 221064562Sgshapiro New command line option '-L tag' which sets the identifier used for 221164562Sgshapiro syslog. Contributed by Exactis.com, Inc. 221264562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 221364562Sgshapiro avoids opening and reading each queue file when preparing 221464562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 221564562Sgshapiro Shared memory counters and microtimers functionality has been 221664562Sgshapiro donated by Exactis.com, Inc. 221764562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 221864562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 221964562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 222064562Sgshapiro being added. Suggested by Michael K. Sanders. 222164562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 222264562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 222364562Sgshapiro and John Beck of Sun Microsystems. 222464562Sgshapiro In low-disk space situations, where sendmail would previously refuse 222564562Sgshapiro connections, still accept them, but only allow ETRN commands. 222664562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 222764562Sgshapiro Ltd. 222864562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 222964562Sgshapiro on systems which support them. This can be used with LMTP 223064562Sgshapiro local delivery agents which listen on a named socket. An 223164562Sgshapiro example mailer might be: 223264562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 223364562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 223464562Sgshapiro A=FILE /var/run/lmtpd 223564562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 223664562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 223764562Sgshapiro instead. 223864562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 223964562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 224064562Sgshapiro connections), IPC (which will be deprecated in a future 224164562Sgshapiro version), and FILE (for UNIX domain socket delivery). 224264562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 224364562Sgshapiro flags. 224464562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 224564562Sgshapiro body of the original message on delivery status 224664562Sgshapiro notifications. 224764562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 224864562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 224964562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 225064562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 225164562Sgshapiro Steve Schweinhart of America Online. 225264562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 225364562Sgshapiro not be set after rulesets are defined. Suggested by 225464562Sgshapiro Mitchell Blank Jr of Exec-PC. 225564562Sgshapiro Do not report temporary failure on delivery to files. In 225664562Sgshapiro interactive delivery mode, this would result in two SMTP 225764562Sgshapiro responses after the DATA command. Problem noted by 225864562Sgshapiro Nik Conwell of Boston University. 225964562Sgshapiro Check file close when mailing to files. Problem noted by Nik 226064562Sgshapiro Conwell of Boston University. 226164562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 226264562Sgshapiro Curtis W. Hillegas of Princeton University. 226364562Sgshapiro Always bind to the LDAP server regardless of whether you are using 226464562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 226564562Sgshapiro @Home Network. 226664562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 226764562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 226864562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 226964562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 227064562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 227164562Sgshapiro similar to check_rcpt etc. 227264562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 227364562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 227464562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 227564562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 227664562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 227764562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 227864562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 227964562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 228064562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 228164562Sgshapiro the corresponding DSN parameter values. Proposed by 228264562Sgshapiro Mathias Herberts. 228364562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 228464562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 228564562Sgshapiro before the message has been collected, thereafter it holds 228664562Sgshapiro the message size as computed by sendmail (and can be used 228764562Sgshapiro in check_compat). 228864562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 228964562Sgshapiro sendmail is using instead of the value of the DeliveryMode 229064562Sgshapiro option. 229164562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 229264562Sgshapiro Drop explicit From: if same as what would be generated only if it is 229364562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 229464562Sgshapiro Write pid to file also if sendmail only processes the queue. 229564562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 229664562Sgshapiro Log "low on disk space" only when necessary. 229764562Sgshapiro New macro ${load_avg} can be used to check the current load average. 229864562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 229964562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 230064562Sgshapiro is set. 230164562Sgshapiro Flag -S for maps to specify the character which is substituted 230264562Sgshapiro for spaces (instead of the default given by O BlankSub). 230364562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 230464562Sgshapiro This flag is set by default for the host map. Based on a 230564562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 230664562Sgshapiro Open maps only on demand, not at startup. 230764562Sgshapiro Log warning about unsupported IP address families. 230864562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 230964562Sgshapiro of the sum of all headers. This can be used to prevent 231064562Sgshapiro a denial-of-service attack. 231164562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 231264562Sgshapiro headers and parameters within those headers. This option 231364562Sgshapiro is intended to protect mail user agents from buffer 231464562Sgshapiro overflow attacks. 231564562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 231664562Sgshapiro alias recursion. 231764562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 231864562Sgshapiro Map type syslog to log the key via syslogd. 231964562Sgshapiro Entries in the alias file can be continued by putting a backslash 232064562Sgshapiro directly before the newline. 232164562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 232264562Sgshapiro dead.letter file, formerly hardcoded to 232364562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 232464562Sgshapiro default), sendmail will not attempt to save to a 232564562Sgshapiro system-wide dead.letter file if it can not bounce the mail 232664562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 232764562Sgshapiro file as it has in the past when the dead.letter file 232864562Sgshapiro could not be opened. 232964562Sgshapiro New option PidFile to define the location of the pid file. The 233064562Sgshapiro value of this option is macro expanded. 233164562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 233264562Sgshapiro process title shown in 'ps' listings. 233364562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 233464562Sgshapiro (along with the already existing macros): 233564562Sgshapiro ${daemon_info} Daemon information, e.g. 233664562Sgshapiro SMTP+queueing@00:30:00 233764562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 233864562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 233964562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 234064562Sgshapiro ${daemon_port} Daemon port, e.g., 25 234164562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 234264562Sgshapiro New macros especially for virtual hosting: 234364562Sgshapiro ${if_name} hostname of interface of incoming connection. 234464562Sgshapiro ${if_addr} address of interface of incoming connection. 234564562Sgshapiro The latter is only set if the interface does not belong to the 234664562Sgshapiro loopback net. 234764562Sgshapiro If a message being accepted via a method other than SMTP and 234864562Sgshapiro would be rejected by a header check, do not send the message. 234964562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 235064562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 235164562Sgshapiro Provide header value as quoted string in the macro 235264562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 235364562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 235464562Sgshapiro The length of the header value is stored in ${hdrlen}. 235564562Sgshapiro H*: allows to specify a default ruleset for header checks. This 235664562Sgshapiro ruleset will only be called if the individual header does 235764562Sgshapiro not have its own ruleset assigned. Suggested by Jan 235864562Sgshapiro Krueger of Unix-AG of University of Hannover. 235964562Sgshapiro The name of the header field stored in ${hdr_name}. 236064562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 236164562Sgshapiro removed if the config file version is greater than or equal 236264562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 236364562Sgshapiro input "token (1)" but does not match "token". 236464562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 236564562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 236664562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 236764562Sgshapiro Ericsson. 236864562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 236964562Sgshapiro messages with 8-bit text in headers. Problem noted by 237064562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 237164562Sgshapiro of Ericsson. 237264562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 237364562Sgshapiro modified database map file. Problem noted by Chris Adams 237464562Sgshapiro of Renaissance Internet Services. 237564562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 237664562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 237764562Sgshapiro queue up the message instead of bouncing it. 237864562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 237964562Sgshapiro standard does not provide any indication of what to do when 238064562Sgshapiro something other than 250 is received. Based on a patch 238164562Sgshapiro from Steve Schweinhart of America Online. 238264562Sgshapiro New option TrustedUser allows to specify a user who can own 238364562Sgshapiro important files instead of root. This requires HASFCHOWN. 238464562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 238564562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 238664562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 238764562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 238864562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 238964562Sgshapiro $? tests also whether the macro is non-null. 239064562Sgshapiro Print an error message if a mailer definition contains an invalid 239164562Sgshapiro equate name. 239264562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 239364562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 239464562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 239564562Sgshapiro mailer to return after sending all data to it. 239664562Sgshapiro Only free memory from the process list when adding a new process 239764562Sgshapiro into a previously filled slot. Previously, the memory was 239864562Sgshapiro freed at removal time. Since removal can happen in a 239964562Sgshapiro signal handler, this may leave the memory map in an 240064562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 240164562Sgshapiro David Cooley of Colby College. 240264562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 240364562Sgshapiro local users in the passwd file. The UserDB code has 240464562Sgshapiro already decided the message will be passed to another host 240564562Sgshapiro for processing. Fix from Tony Landells of Burdett 240664562Sgshapiro Buckeridge Young Limited. 240764562Sgshapiro Support LDAP authorization via either a file containing the 240864562Sgshapiro password or Kerberos V4 using the new map options 240964562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 241064562Sgshapiro distinguished_name is who to login as. The method can be 241164562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 241264562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 241364562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 241464562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 241564562Sgshapiro of Stanford University. 241664562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 241764562Sgshapiro deprecated and will be removed in a future version. 241864562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 241964562Sgshapiro and the map has the column delimiter set, it turns that 242064562Sgshapiro response into a delimiter separated string. The LDAP map 242164562Sgshapiro will traverse multiple entries as well. LDAP alias maps 242264562Sgshapiro automatically set the column delimiter to the comma. 242364562Sgshapiro Based on patch from Booker Bense of Stanford University and 242464562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 242564562Sgshapiro Support return of multiple values for a single LDAP lookup. The 242664562Sgshapiro values to be returned should be in a comma separated string. 242764562Sgshapiro For example, `-v "email,emailother"'. Patch from 242864562Sgshapiro Curtis W. Hillegas of Princeton University. 242964562Sgshapiro Allow the use of LDAP for alias maps. 243064562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 243164562Sgshapiro attributes found in the match will be returned. 243264562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 243364562Sgshapiro breaking up a single entry into multiple entries. This is 243464562Sgshapiro needed for LDAP alias file specifications to allow for 243564562Sgshapiro comma separated key and value strings. 243664562Sgshapiro Keep connections to LDAP server open instead of opening and closing 243764562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 243864562Sgshapiro connections such that multiple maps which use the same 243964562Sgshapiro host, port, bind DN, and authentication will only result in 244064562Sgshapiro a single connection to that host. 244164562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 244264562Sgshapiro Be more careful about checking for errors and freeing memory on 244364562Sgshapiro LDAP lookups. 244464562Sgshapiro Use asynchronous LDAP searches to save memory and network 244564562Sgshapiro resources. 244664562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 244764562Sgshapiro Increase portability to the Netscape LDAP libraries. 244864562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 244964562Sgshapiro replaced with the literal contents of the map lookup key -- 245064562Sgshapiro note that this means a lookup can be done using the LDAP 245164562Sgshapiro special characters. The new '%0' token can be used instead 245264562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 245364562Sgshapiro For example, if the LDAP map specification contains '-k 245464562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 245564562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 245664562Sgshapiro user attribute. Instead, if the LDAP map specification 245764562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 245864562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 245964562Sgshapiro with the name "*". 246064562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 246164562Sgshapiro more than one is returned, it is equivalent to no records 246264562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 246364562Sgshapiro alias dereference option; "-Z size" limits the number of 246464562Sgshapiro matches to return. 246564562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 246664562Sgshapiro LDAP maps. The value should only contain LDAP specific 246764562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 246864562Sgshapiro settings will be used for all LDAP maps unless they are 246964562Sgshapiro specified in the individual map specification ('K' 247064562Sgshapiro command). This option should be set before any LDAP maps 247164562Sgshapiro are defined. 247264562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 247364562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 247464562Sgshapiro Tech. 247564562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 247664562Sgshapiro particular, class entries get much smaller, which can be 247764562Sgshapiro important if you have large classes. 247864562Sgshapiro On network-related temporary failures, record the hostname which 247964562Sgshapiro gave error in the queued status message. Requested by 248064562Sgshapiro Ulrich Windl of the Universitat Regensburg. 248164562Sgshapiro Add new F=% mailer flag to allow for a store and forward 248264562Sgshapiro configuration. Mailers which have this flag will not attempt 248371345Sgshapiro delivery on initial receipt of a message or on queue runs 248464562Sgshapiro unless the queued message is selected using one of the 248564562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 248664562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 248764562Sgshapiro New option ControlSocketName which, when set, creates a daemon 248864562Sgshapiro control socket. This socket allows an external program to 248964562Sgshapiro control and query status from the running sendmail daemon 249064562Sgshapiro via a named socket, similar to the ctlinnd interface to the 249164562Sgshapiro INN news server. Access to this interface is controlled by 249264562Sgshapiro the UNIX file permissions on the named socket on most UNIX 249364562Sgshapiro systems (see sendmail/README for more information). An 249464562Sgshapiro example control program is provided as contrib/smcontrol.pl. 249564562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 249664562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 249764562Sgshapiro number of processors online on the system (if that can be 249864562Sgshapiro determined). For single processor machines, this change 249964562Sgshapiro has no effect. 250064562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 250164562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 250264562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 250364562Sgshapiro Motonori Nakamura of Kyoto University. 250464562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 250564562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 250664562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 250764562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 250864562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 250964562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 251064562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 251164562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 251264562Sgshapiro connection-based denial of service attacks. 251364562Sgshapiro Log basic information about authenticated connections at LogLevel 251464562Sgshapiro 10 or higher. 251564562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 251664562Sgshapiro information (from= syslog line). 251764562Sgshapiro Log the DSN code for each recipient if one is available as a new 251864562Sgshapiro equate (dsn=). 251964562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 252064562Sgshapiro New "ph" map for performing ph queries in rulesets.

Contributed by Mark 252371345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 252464562Sgshapiro Detect temporary lookup failures in the host map if looking up a 252564562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 252664562Sgshapiro Finnish Meteorological Institute. 252764562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 252864562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 252964562Sgshapiro When a forward file points to an alias which runs a program, run 253064562Sgshapiro the program as the default user and the default group, not 253164562Sgshapiro the forward file user. This change also assures the 253264562Sgshapiro :include: directives in aliases are also processed using 253364562Sgshapiro the default user and group. Problem noted by Sergiu 253464562Sgshapiro Popovici of DNT Romania. 253564562Sgshapiro Prevent attempts to save a dead.letter file for a user with 253664562Sgshapiro no home directory (/no/such/directory). Problem noted by 253764562Sgshapiro Michael Brown of Finnigan FT/MS. 253864562Sgshapiro Include message delay and number of tries when logging that a 253964562Sgshapiro message has been completely delivered (LogLevel of 10 or 254064562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 254164562Sgshapiro Log the sender of a message even if none of the recipients were 254264562Sgshapiro accepted. If some of the recipients were rejected, it is 254364562Sgshapiro helpful to know the sender of the message. 254464562Sgshapiro Check the root directory (/) when checking a path for safety. 254564562Sgshapiro Problem noted by John Beck of Sun Microsystems. 254664562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 254764562Sgshapiro interactive and delivering to an alias which resolves to 254864562Sgshapiro multiple files. 254964562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 255064562Sgshapiro greater (see below); the help function doesn't print the 255164562Sgshapiro version of sendmail any longer, instead it is placed in 255264562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 255364562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 255464562Sgshapiro skipped and a version line (#vers) is introduced. The 255564562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 255664562Sgshapiro version is found, a warning is logged. The '#vers' 255764562Sgshapiro directive should be placed at the top of the help file. 255864562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 255964562Sgshapiro disk succeeded. Suggested by Nick Christenson. 256064562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 256164562Sgshapiro length before the attempt. 256264562Sgshapiro If a forward points to a filename for delivery, change to the 256364562Sgshapiro user's uid before checking permissions on the file. This 256464562Sgshapiro allows delivery to files on NFS mounted directories where 256564562Sgshapiro root is remapped to nobody. Problem noted by Harald 256664562Sgshapiro Daeubler of Universitaet Ulm. 256764562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 256864562Sgshapiro host status files, not all files. 256964562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 257064562Sgshapiro in the queue file for the message and set when delivery 257164562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 257264562Sgshapiro Wonderworks Inc. 257364562Sgshapiro Add support for storing information between rulesets using the new 257464562Sgshapiro macro map class. This can be used to store information 257564562Sgshapiro between queue runs as well using $={persistentMacros}. 257664562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 257764562Sgshapiro of Hannover. 257864562Sgshapiro New map class arith to allow for computations in rules. The 257964562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 258064562Sgshapiro as key. The two operands are specified as arguments; the 258164562Sgshapiro lookup returns the result of the computation. For example, 258264562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 258364562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 258464562Sgshapiro Add new syntax for header declarations which decide whether to 258564562Sgshapiro include the header based on a macro rather than a mailer 258664562Sgshapiro flag: 258764562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 258864562Sgshapiro This should be used along with $={persistentMacros}. 258964562Sgshapiro It can be used for adding headers to a message based on 259064562Sgshapiro the results of check_* and header check rulesets. 259164562Sgshapiro Allow new named config file rule check_eoh which is called after 259264562Sgshapiro all of the headers have been collected. The input to the 259364562Sgshapiro ruleset the number of headers and the size of all of the 259464562Sgshapiro headers in bytes separated by $|. This ruleset along with 259564562Sgshapiro the macro storage map can be used to correlate information 259664562Sgshapiro gathered between headers and to check for missing headers. 259764562Sgshapiro See cf/README or doc/op/op.ps for an example. 259864562Sgshapiro Change the default for the MeToo option to True to correspond 259964562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 260064562Sgshapiro option is deprecated and will be removed from a future 260164562Sgshapiro version. 260264562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 260364562Sgshapiro Change the sendmail binary default for SuperSafe to True. 260464562Sgshapiro Display ruleset names in debug and address test mode output 260564562Sgshapiro if referencing a named ruleset. 260664562Sgshapiro New mailer equate m= which will limit the number of messages 260764562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 260864562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 260964562Sgshapiro using it to sort. Now all the same domains are really run 261064562Sgshapiro through the queue together. If they have the same MX host, 261164562Sgshapiro then they will have a much better opportunity to use the 261264562Sgshapiro connection cache if available. This should be a reasonable 261364562Sgshapiro performance improvement. Patch from Randall Winchester of 261464562Sgshapiro the University of Maryland. 261564562Sgshapiro If a message is rejected by a header check ruleset, log who would 261664562Sgshapiro have received the message if it had not been rejected. 261764562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 261864562Sgshapiro queue immediately. No delivery attempt is made. 261964562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 262064562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 262164562Sgshapiro COMMANDS). 262264562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 262364562Sgshapiro but for outgoing connections. 262464562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 262564562Sgshapiro error messages and logging) and Modifiers, i.e. 262664562Sgshapiro a require authentication 262764562Sgshapiro b bind to interface through which mail has 262864562Sgshapiro been received 262964562Sgshapiro c perform hostname canonification 263064562Sgshapiro f require fully qualified hostname 263164562Sgshapiro h use name of interface for outgoing HELO 263264562Sgshapiro command 263364562Sgshapiro C don't perform hostname canonification 263464562Sgshapiro E disallow ETRN (see RFC 2476) 263564562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 263664562Sgshapiro h use name of interface for HELO command 263764562Sgshapiro The version number for queue files (qf) has been incremented to 4. 263864562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 263964562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 264064562Sgshapiro Institutes of Health. 264164562Sgshapiro If a mailer dies, print the status in decimal instead of octal 264264562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 264364562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 264464562Sgshapiro Move message priority from sender to recipient logging. Suggested by 264564562Sgshapiro Ulrich Windl of the Universitat Regensburg. 264664562Sgshapiro Add support for Berkeley DB 3.X. 264764562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 264864562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 264964562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 265064562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 265164562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 265264562Sgshapiro sub-options is set on the command line. Problem noted by 265364562Sgshapiro Graeme Hewson of Oracle. 265464562Sgshapiro Randomize equal preference MX records each time delivery is 265564562Sgshapiro attempted via a new connection to a host instead of once per 265664562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 265764562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 265864562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 265964562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 266064562Sgshapiro to hosts which have dynamically assigned names. 266164562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 266264562Sgshapiro the bounce for the same reason. If the body is not 8-bit 266364562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 266464562Sgshapiro not be included in the bounce. Problem noted by Valdis 266564562Sgshapiro Kletnieks of Virginia Tech. 266664562Sgshapiro The timeout for sending a message via SMTP has been changed from 266764562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 266864562Sgshapiro simply checks for progress on sending data every 5 minutes. 266964562Sgshapiro This will detect the inability to send information quicker 267064562Sgshapiro and reduce the number of processes simply waiting to 267164562Sgshapiro timeout. 267264562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 267364562Sgshapiro interface address structure when loading the system network 267464562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 267564562Sgshapiro Nanoteq. 267664562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 267764562Sgshapiro indicates the number of interfaces to read when probing 267864562Sgshapiro for hostnames and IP addresses for class w ($=w). The 267964562Sgshapiro default value is 512. Based on idea from Reinier 268064562Sgshapiro Bezuidenhout of Nanoteq. 268164562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 268264562Sgshapiro on load average. 268364562Sgshapiro Allow ruleset 0 to have a name.

Requested by Il Oh of 306064562Sgshapiro Willamette Industries, Inc. 306164562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 306264562Sgshapiro converted to <user@d> 306364562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 306464562Sgshapiro Sun's older, broken configuration files. 306564562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 306664562Sgshapiro normal configuration, allowing anti-spam checks to be 306764562Sgshapiro performed. 306864562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 306964562Sgshapiro ${client_name} can't be resolved just temporarily. 307064562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 307164562Sgshapiro Institute. 307264562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 307364562Sgshapiro be accessed by their numbers). 307464562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 307564562Sgshapiro which describes whether to disallow "!" in the local part 307664562Sgshapiro of an address. 307764562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 307864562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 307964562Sgshapiro set. If the ruleset returns a mailer, the appropriate 308064562Sgshapiro action is taken, otherwise the returned tokens are ignored. 308164562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 308264562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 308364562Sgshapiro The latter is kept around for backward compatibility. 308464562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 308564562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 308664562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 308764562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 308864562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 308964562Sgshapiro Institute. 309064562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 309164562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 309264562Sgshapiro arguments overriding the mailer program, arguments, and 309364562Sgshapiro mailer definition flags. This makes it possible to use 309464562Sgshapiro other programs such as maildrop for local delivery. 309564562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 309664562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 309764562Sgshapiro Patch from Richard A.

Problem noted by Per Hedeland of Ericsson. 310264562Sgshapiro CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the 310364562Sgshapiro University of California at Berkeley. 310464562Sgshapiro CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of 310564562Sgshapiro Illinois at Urbana-Champaign. 310664562Sgshapiro CONTRIB: etrn.pl now recognizes bogus host names. Patch from 310764562Sgshapiro Bruce Barnett of GE's R&D Lab. 310864562Sgshapiro CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle 310964562Sgshapiro Corporation UK. 311064562Sgshapiro CONTRIB: Added qtool.pl to assist in managing the queues. 311164562Sgshapiro DEVTOOLS: Prevent user environment variables from interfering with 311264562Sgshapiro the Build scripts. Problem noted by Ezequiel H. Panepucci of 311364562Sgshapiro Yale University. 311464562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 311564562Sgshapiro be used for building. 311664562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 311764562Sgshapiro used for a fresh build. 311864562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 311964562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 312064562Sgshapiro ranlib. 312164562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 312264562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 312364562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 312464562Sgshapiro building of the man pages when defined. Suggested by Bryan 312564562Sgshapiro Costales. 312664562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 312764562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 312864562Sgshapiro installation of the sendmail helpfile and statistics file 312964562Sgshapiro respectively. Suggested by Bryan Costales. 313064562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 313164562Sgshapiro of Siemens Business Services. 313264562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 313364562Sgshapiro stdio library. The new buffered file I/O depends on the 313464562Sgshapiro Torek stdio library. This option can be either portable or 313564562Sgshapiro torek. 313664562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 313764562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 313864562Sgshapiro They should contain the C source files for the object files 313964562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 314064562Sgshapiro will be passed to the 'make depend' stage of compilation. 314164562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 314264562Sgshapiro in the sendmail distribution. Each has the form 314364562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 314464562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 314564562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 314664562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 314764562Sgshapiro building the distribution, but documentation on the changes 314864562Sgshapiro are in devtools/README. 314964562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 315064562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 315164562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 315264562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 315364562Sgshapiro new variable which identifies the root of the source 315464562Sgshapiro directories for all of the programs in the distribution. 315564562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 315664562Sgshapiro time. They can both still be overridden by setting the m4 315764562Sgshapiro macro. 315864562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 315964562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 316064562Sgshapiro build configurations, and places objects in obj.prefix.*/. 316164562Sgshapiro Complains as 'Build -f file' does for existing object 316264562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 316364562Sgshapiro Corporation. 316464562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 316564562Sgshapiro manual pages in the directory tree specified by 316664562Sgshapiro confMANROOTMAN. 316764562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 316864562Sgshapiro preformatted pages from the distribution. The new variable 316964562Sgshapiro confCOPY specifies the copying program. 317064562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 317164562Sgshapiro question. Suggested by Terry Lambert of Whistle 317264562Sgshapiro Communications. 317364562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 317464562Sgshapiro of the installed statistics and help files, respectively. 317564562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 317664562Sgshapiro operating system identity. Problem noted by Erik 317764562Sgshapiro Wachtenheim of Dartmouth College. 317864562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 317964562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 318064562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 318164562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 318264562Sgshapiro how to strip binaries. These are used by the new 318364562Sgshapiro install-strip target. 318464562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 318564562Sgshapiro the others (if it exists). 318664562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 318764562Sgshapiro then the default ones. 318890792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 318964562Sgshapiro as local delivery agent without LMTP mode, use 319064562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 319164562Sgshapiro to set the S flag. 319264562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 319364562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 319464562Sgshapiro Northern Illinois University. 319564562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 319664562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 319764562Sgshapiro the Finnish Meteorological Institute. 319864562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 319964562Sgshapiro MAILLOCK when compiling. Also requires linking with 320064562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 320164562Sgshapiro University. 320264562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 320364562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 320464562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 320564562Sgshapiro University. 320664562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 320764562Sgshapiro structure to the beginning of the program. This ensures that 320864562Sgshapiro the getservbyname() is done before any seteuid to a possibly 320964562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 321064562Sgshapiro on a Solaris system, this avoids syslog messages such as, 321164562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 321264562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 321364562Sgshapiro University. 321464562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 321564562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 321664562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 321764562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 321864562Sgshapiro characters (in LMTP mode), mail.local split the incoming 321964562Sgshapiro line up into 2046-character output lines (excluding the 322064562Sgshapiro newline). If an input line was 2047 characters long 322164562Sgshapiro (excluding CR-LF) and the last character was a '.', 322264562Sgshapiro mail.local saw it as the end of input, transfered it to the 322364562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 322464562Sgshapiro If the message was much longer, both sendmail and 322564562Sgshapiro mail.local would deadlock waiting for each other to read 322664562Sgshapiro what they have written. Problem noted by Peter Jeremy of 322764562Sgshapiro Alcatel Australia Limited. 322864562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 322964562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 323064562Sgshapiro Neil Rickert of Northern Illinois University. 323164562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 323264562Sgshapiro timeout to avoid starvation. 323364562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 323464562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 323564562Sgshapiro Infinite Monkeys & Co. 323664562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 323764562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 323864562Sgshapiro printed in a machine readable fashion and the stats file 323964562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 324064562Sgshapiro of Maryland. 324164562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 324264562Sgshapiro generated maps to the TrustedUser as specified in the 324364562Sgshapiro sendmail configuration file. 324464562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 324564562Sgshapiro configuration file to use for finding the TrustedUser 324664562Sgshapiro option. 324764562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 324864562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 324964562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 325064562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 325164562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 325264562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 325364562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 325464562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 325564562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 325664562Sgshapiro Corporation UK. 325764562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 325864562Sgshapiro (e.g., sendmail would not drop root privileges if the 325964562Sgshapiro option was specified on the command line). Problem noted 326064562Sgshapiro by Todd C. Miller of Courtesan Consulting. 326164562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 326264562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 326364562Sgshapiro Institute for Global Communications. 326464562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 326564562Sgshapiro alias file(s) if the -f option is not used. Patch from 326664562Sgshapiro John Beck of Sun Microsystems. 326764562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 326864562Sgshapiro configuration file to use for finding alias file(s). Patch 326964562Sgshapiro from John Beck of Sun Microsystems. 327064562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 327164562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 327264562Sgshapiro of the Institute for Global Communications. 327364562Sgshapiro SMRSH: Update README for the new Build system.

Sites 371838032Speter which need the ability to override security can use the 371938032Speter DontBlameSendmail option. See the README file for more 372038032Speter information. 372138032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 372238032Speter if maps or alias files are in world writable directories. 372338032Speter This fixes the change added to 8.8.6 to prevent links in these 372438032Speter world writable directories. 372538032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 372638032Speter it is in a world writable directory. 372738032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 372838032Speter tty it may be able to push bytes back to the senders input. 372938032Speter Unfortunately this breaks -v mode.

After this number is reached, sendmail 378938032Speter starts returning "452 Too many recipients" to all RCPT 379038032Speter commands. This can be used to limit the number of recipients 379138032Speter per envelope (in particular, to discourage use of the server 379238032Speter for spamming). Note: a better approach is to restrict 379338032Speter relaying entirely. 379438032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 379538032Speter to ldapx map and added timeout for ldap_open call to 379638032Speter avoid hanging sendmail in the event of hung LDAP servers. 379738032Speter Patch from Booker Bense of Stanford University. 379838032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 381738032Speter of Procter & Gamble. 381838032Speter The LDAP map -s flag was not properly parsed and the error message 381964562Sgshapiro given included the remainder of the arguments instead of 382038032Speter solely the argument in error. Problem noted by Aidan Nichol 382138032Speter of Procter & Gamble. 382238032Speter New DontBlameSendmail option. This option allows administrators to 382338032Speter bypass some of sendmail's file security checks at the expense 382438032Speter of system security.

In particular, if you 386038032Speter have lots of virtual interfaces, this option will speed up 386138032Speter startup. However, unless you make other arrangements, mail 386238032Speter sent to those addresses will be bounced. 386338032Speter Automatically create alias databases if they don't exist and 386438032Speter AutoRebuildAliases is set. 386538032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 386638032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 386738032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 386838032Speter When determining the client host name ($&{client_name} macro), do 386938032Speter a forward (A) DNS lookup on the result of the PTR lookup 387038032Speter and compare results. If they differ or if the PTR lookup 387138032Speter fails, &{client_name} will contain the IP address 387264562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 387338032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 387438032Speter (i.e, it is like -ax for the temporary failure case, in 387538032Speter contrast to the success case). 387638032Speter New syntax to do limited checking of header syntax. A config line 387738032Speter of the form: 387838032Speter HHeader: $>Ruleset 387938032Speter causes the indicated Ruleset to be invoked on the Header 388038032Speter when read. This ruleset works like the check_* rulesets -- 388138032Speter that is, it can reject mail on the basis of the contents. 388238032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 388338032Speter from hiding their connection information in Received: 388438032Speter headers. 388538032Speter When SingleThreadDelivery is active, deliveries to locked hosts 388638032Speter are skipped. This will cause the delivering process to 388738032Speter try the next MX host or queue the message if no other MX 388838032Speter hosts are available. Suggested by Alexander Litvin. 388938032Speter The [FILE] mailer type now delivers to the file specified in the 389038032Speter A= equate of the mailer definition instead of $u. It also 389138032Speter obeys all of the F= mailer flags such as the MIME 389238032Speter 7/8 bit conversion flags. This is useful for defining 389338032Speter a mailer which delivers to the same file regardless of the 389464562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 389538032Speter Do not assume the identity of a remote connection is root@localhost 389638032Speter if the remote connection closes the socket before the 389738032Speter remote identity can be queried. 389838032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 389938032Speter Some mailers, including procmail, require that the real 390038032Speter uid is left unchanged by sendmail. Problem noted by Per 390138032Speter Hedeland of Ericsson. 390238032Speter No longer is the src/obj*/Makefile selected from a large list -- it 390338032Speter is now generated using the information in BuildTools/OS/ -- 390438032Speter some of the details are determined dynamically via 390538032Speter BuildTools/bin/configure.sh. 390638032Speter The other programs in the sendmail distribution -- mail.local, 390738032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 390838032Speter the new Build method which creates an operating system 390938032Speter specific Makefile using the information in BuildTools. 391038032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 391138032Speter a failure on one message won't affect future messages to the 391238032Speter same host). This is necessary if the remote host sends 391338032Speter a 451 error if the domain of the sender does not resolve 391438032Speter as is common in anti-spam configurations. Problem noted 391538032Speter by Mitchell Blank Jr of Exec-PC. 391638032Speter New "discard" mailer for check_* rulesets and header checking 391738032Speter rulesets. If one of the above rulesets resolves to the 391838032Speter $#discard mailer, the commands will be accepted but the 391938032Speter message will be completely discarded after it is accepting. 392038032Speter This means that even if only one of the recipients 392138032Speter resolves to the $#discard mailer, none of the recipients 392238032Speter will receive the mail. Suggested by Brian Kantor. 392338032Speter All but the last cloned envelope of a split envelope were queued 392438032Speter instead of being delivered.

Problem noted by 395838032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 395938032Speter Include a magic number and version in the StatusFile for the 396038032Speter mailstats command. 396138032Speter Record the number of rejected and discarded messages in the 396238032Speter StatusFile for display by the mailstats command. Patch 396338032Speter from Randall Winchester of the University of Maryland. 396438032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 396538032Speter user portion as IDENT:username@site instead of 396638032Speter username@site to differentiate the two. Suggested by 396738032Speter Kari Hurtta of the Finnish Meteorological Institute. 396838032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 396938032Speter Ericsson. 397038032Speter Change persistent host status filename substitution so '/' is 397138032Speter replaced by ':' instead of '|' to avoid clashes. Also 397238032Speter avoid clashes with hostnames with leading dots. Fix from 397338032Speter Mitchell Blank Jr. of Exec-PC. 397438032Speter If the system lock table is full, only attempt to create a new 397538032Speter queue entry five times before giving up. Previously, it 397638032Speter was attempted indefinitely which could cause the partition 397738032Speter to run out of inodes. Problem noted by Suzie Weigand of 397838032Speter Stratus Computer, Inc. 397938032Speter In verbose mode, warn if the sendmail.cf version is less than the 398038032Speter currently supported version. 398138032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 398238032Speter from Randall S. Winchester of the University of Maryland. 398338032Speter Properly quote a full name passed via the -F command line option, 398438032Speter the Full-Name: header, or the NAME environment variable if 398538032Speter it contains characters which must be quoted. Problem noted 398638032Speter by Kari Hurtta of the Finnish Meteorological Institute. 398738032Speter Avoid possible race condition that unlocked a mail job before 398838032Speter releasing the transcript file on systems that use flock(2). 398938032Speter In some cases, this might result in a "Transcript Unavailable" 399038032Speter message in error bounces. 399138032Speter Accept SMTP replies which contain only a reply code and no 399238032Speter accompanying text. Problem noted by Fernando Fraticelli of 399338032Speter Digital Equipment Corporation. 399438032Speter Portability: 399538032Speter AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura 399638032Speter of Kyoto University. 399738032Speter AIX 4.2 requires <userpw.h> before <usersec.h>.

From Guillermo Freige of 401838032Speter Gobernacion de la Pcia de Buenos Aires and Paul 401938032Speter Fischer of BTG, Inc. 402038032Speter SunOS 4.X does not include memmove(). Patch from 402138032Speter Per Hedeland of Ericsson. 402238032Speter SunOS 5.7 includes getloadavg() function for determining 402338032Speter load average. Patch from John Beck of Sun 402438032Speter Microsystems. 402538032Speter CONFIG: Increment version number of config file. 402638032Speter CONFIG: add DATABASE_MAP_TYPE to set the default type of database 402738032Speter map for the various maps. The default is hash. Patch from 402838032Speter Robert Harker of Harker Systems. 402938032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 403038032Speter directory for certain programs. 403138032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 403238032Speter local mail delivery. By the default, /usr/libexec/mail.local 403338032Speter is used. This is expected to be the mail.local shipped 403438032Speter with 8.9 which is LMTP capable. The path is based on the 403538032Speter new confEBINDIR m4 variable. 403638032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 403738032Speter FEATURE(smrsh). Note that this changes the default from 403838032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 403938032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 404038032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 404138032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 404238032Speter the user to setup different .forward files for 404338032Speter user+detail addressing. 404438032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 404538032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 404638032Speter DontProbeInterfaces, and DontBlameSendmail options. 404738032Speter CONFIG: by default do not allow relaying (that is, accepting mail 404838032Speter from outside your domain and sending it to another host 404938032Speter outside your domain). 405038032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 405138032Speter any site to any site. 405238032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 405338032Speter domain as defined by the 'm' class ($=m) to relay. 405438032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 405538032Speter the MX records of the host portion of an incoming recipient. 405638032Speter CONFIG: new FEATURE(access_db) which turns on the access database 405777349Sgshapiro feature. This database gives you the ability to allow 405838032Speter or refuse to accept mail from specified domains for 405938032Speter administrative reasons. By default, names that are listed 406038032Speter as "OK" in the access db are domain names, not host names. 406138032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 406238032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 406338032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 406438032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 406538032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 406638032Speter of FEATURE(access_db) and class 'R' to lookup individual 406738032Speter host names only. 406838032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 406938032Speter using % addressing is used, e.g. user%site@othersite, 407038032Speter and othersite is in class 'R', the check_rcpt ruleset 407138032Speter will strip @othersite and recheck user@site for relaying. 407238032Speter This feature changes that behavior. It should not be 407338032Speter needed for most installations. 407438032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 407538032Speter domain portion of the mail sender is a local host. This 407638032Speter should only be used if absolutely necessary as it opens 407738032Speter a window for spammers. Patch from Randall S. Winchester of 407838032Speter the University of Maryland. 407938032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 408038032Speter block incoming mail destined for certain recipient 408138032Speter usernames, hostnames, or addresses. 408238032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 408338032Speter refused if the host part of the argument to MAIL FROM: cannot 408438032Speter be located in the host name service (e.g., DNS). 408538032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 408638032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 408738032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 408838032Speter MAIL FROM: senders which do not include a domain. 408938032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 409038032Speter Realtime Blackhole List. You can specify the RBL name 409138032Speter server to contact by specifying it as an optional argument. 409238032Speter The default is rbl.maps.vix.com. For details, see 409338032Speter http://maps.vix.com/rbl/. 409438032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 409538032Speter Local_check_rcpt from check_relay, check_mail, and 409638032Speter check_rcpt. Users with local rulesets should place the 409738032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 409838032Speter returns $#OK, the message is accepted. If the ruleset 409938032Speter returns a mailer, the appropriate action is taken, else 410038032Speter the return of the ruleset is ignored. 410138032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 410238032Speter default to support file, :include:, and program deliveries. 410338032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 410438032Speter pick the proper default value. See the SECURITY note 410538032Speter above for more information. 410638032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 410738032Speter no-op. Patch from Kari Hurtta of the Finnish 410838032Speter Meteorological Institute. 410938032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 411038032Speter daemon since DEC's /bin/mail will drop the envelope 411138032Speter sender if run as mailnull. See the Digital UNIX section 411238032Speter of src/README for more information. Problem noted by 411338032Speter Kari Hurtta of the Finnish Meteorological Institute. 411438032Speter CONFIG: .cf files are now stored in the same directory with the 411538032Speter .mc files instead of in the obj directory. 411664562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 411738032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 411838032Speter setting SingleLineFromHeader, AllowBogusHELO, and 411938032Speter MustQuoteChars respectively. 412038032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout. This 412138032Speter SMTP-like protocol allows detailed reporting of delivery 412238032Speter status on a per-user basis. Code donated by John Myers of 412338032Speter CMU (now of Netscape). 412438032Speter MAIL.LOCAL: HP-UX support from Randall S. Winchester of the 412564562Sgshapiro University of Maryland. NOTE: mail.local is not 412638032Speter compatible with the stock HP-UX mail format. Be sure to 412738032Speter read mail.local/README. 412838032Speter MAIL.LOCAL: Prevent other mail delivery agents from stealing a 412938032Speter mailbox lock. Patch from Randall S.

Problem noted by Greg Nichols of Wind 425338032Speter River Systems. 425438032Speter If SingleThreadDelivery was enabled and the remote server returned a 425538032Speter protocol error on the DATA command, the connection would be 425638032Speter closed but the persistent host status file would not be 425738032Speter unlocked so other sendmail processes could not deliver to 425838032Speter that host. Problem noted by Peter Wemm of DIALix. 425938032Speter If queueing up a message due to an expensive mailer, don't increment 426038032Speter the number of delivery attempts or set the last delivery 426138032Speter attempt time so the message will be delivered on the next 426238032Speter queue run regardless of MinQueueAge. Problem noted by 426338032Speter Brian J. Coan of the Institute for Global Communications. 426438032Speter Authentication warnings of "Processed from queue _directory_" and 426538032Speter "Processed by _username_ with -C _filename_" would be logged 426638032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 426738032Speter of the Finnish Meteorological Institute. 426838032Speter Use a better heuristic for detecting GDBM. 426938032Speter Log null connections on dropped connections. Problem noted by 427038032Speter Jon Lewis of Florida Digital Turnpike. 427138032Speter If class dbm maps are rebuilt, sendmail will now detect this and 427238032Speter reopen the map. Previously, they could give stale 427338032Speter results during a single message processing (but would 427438032Speter recover when the next message was received). Fix from 427538032Speter Joe Pruett of Q7 Enterprises. 427638032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 427738032Speter requests. Problem noted by Kari E. Hurtta of the 427838032Speter Finnish Meteorological Institute. 427938032Speter Do not send a bounce message back to the sender regarding bad 428038032Speter recipients if the SMTP connection is dropped before the 428138032Speter message is accepted. Problem noted by Kari E. Hurtta of the 428238032Speter Finnish Meteorological Institute. 428338032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 428438032Speter sendmail via a UNIX pipe. This will allow rulesets using 428538032Speter $&{client_name} to process without sending the string through 428638032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 428738032Speter A combination of deferred delivery mode, a double bounce situation, 428838032Speter and the inability to save a bounce message to 428938032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 429038032Speter to postmaster but not remove the offending envelope from the 429138032Speter queue causing it to create a new bounce message each time the 429238032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 429338032Speter Associates. 429438032Speter Remove newlines from hostname information returned via DNS. There are 429538032Speter no known security implications of newlines in hostnames as 429638032Speter sendmail filters newlines in all vital areas; however, this 429738032Speter could cause confusing error messages. 429838032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 429938032Speter rejected if any of the specified addresses were bad. This 430038032Speter behavior was modified to only reject the bad addresses and not 430138032Speter the entire message.

From Tetsu Ushijima of the 442238032Speter Tokyo Institute of Technology. 442338032Speter Fix race condition that could cause the body of a message to be 442438032Speter lost (so only the header was delivered).

Based on a patch from Steve Schweinhart of 442838032Speter Results Computing. 442938032Speter If a qf file was found in a mail queue directory that had a problem 443038032Speter (wrong ownership, bad format, etc.) and the file name was 443138032Speter exactly MAXQFNAME bytes long, then instead of being tried 443238032Speter once, it would be tried on every queue run. Problem noted 443338032Speter by Bryan Costales of Mercury Mail. 443438032Speter If the system supports an st_gen field in the status structure, 443538032Speter include it when reporting that a file has changed after open. 443638032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 443738032Speter This out to be checked as well as reported, since it is 443838032Speter theoretically possible for an attacker to remove a file after 443938032Speter it is opened and replace it with another file that has the 444038032Speter same i-number, but some filesystems (notably AFS) return 444138032Speter garbage in this field, and hence always look like the file 444238032Speter has changed. As a practical matter this is not a security 444338032Speter problem, since the files can be neither hard nor soft links, 444438032Speter and on no filesystem (that I am aware of) is it possible to 444538032Speter have two files on the same filesystem with the same i-number 444638032Speter simultaneously. 444738032Speter Delete the root Makefile from the distribution -- it is only for 444838032Speter use internally, and does not work at customer sites. 444938032Speter Fix botch that caused the second MAIL FROM: command in a single 445038032Speter transaction to clear the entire transaction.

This makes it possible to create a root 453638032Speter owned file in an arbitrary directory by inserting the symlink 453738032Speter into a writable directory after the initial lstat(2) check 453838032Speter determined that the file did not exist. The only verified 453938032Speter example of a system having these odd semantics for O_EXCL 454038032Speter and symbolic links was HP-UX prior to version 9.07. Most 454138032Speter systems do not have the problem, since a exclusive create 454238032Speter of a file disallows symbolic links. Systems that have been 454338032Speter verified to NOT have the problem include AIX 3.x, *BSD, 454438032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 454538032Speter and Ultrix. This is a potential exposure on systems that 454638032Speter have this bug and which do not have a MAILER-DAEMON alias 454738032Speter pointing at a legitimate account, since this will cause old 454838032Speter mail to be dropped in /var/tmp/dead.letter. 454938032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 455038032Speter if maps or alias files are in world writable directories. 455138032Speter If your system has alias maps in writable directories, it 455238032Speter is potentially possible for an attacker to replace the .db 455338032Speter (or .dir and .pag) files by symbolic links pointing at 455438032Speter another database; this can be used either to expose 455538032Speter information (e.g., by pointing an alias file at /etc/spwd.db 455638032Speter and probing for accounts), or as a denial-of-service attack 455738032Speter (by trashing the password database). The fix disallows 455838032Speter symbolic links entirely when rebuilding alias files or on 455938032Speter maps that are in writable directories, and always warns on 456038032Speter writable directories; 8.9 will probably consider writable 456138032Speter directories to be fatal errors. This does not represent an 456238032Speter exposure on systems that have alias files in unwritable 456338032Speter system directories. 456438032Speter SECURITY: disallow .forward or :include: files that are links (hard 456538032Speter or soft) if the parent directory (or any directory in the 456638032Speter path) is writable by anyone other than the owner. This is 456738032Speter similar to the previous case for user files. This change 456838032Speter should not affect most systems, but is necessary to prevent 456938032Speter an attacker who can write the directory from pointing such 457038032Speter files at other files that are readable only by the owner. 457138032Speter SECURITY: Tighten safechown rules: many systems will say that they 457238032Speter have a safe (restricted to root) chown even on files that 457338032Speter are mounted from another system that allows owners to give 457438032Speter away files. The new rules are very strict, trusting file 457538032Speter ownership only in those few cases where the system has 457638032Speter been verified to be at least as paranoid as necessary. 457738032Speter However, it is possible to relax the rules to partially 457838032Speter trust the ownership if the directory path is not world or 457938032Speter group writable. This might allow someone who has a legitimate 458038032Speter :include: file (referenced directly from /etc/aliases) to 458138032Speter become another non-root user if the :include: file is in a 458238032Speter non-writable directory on an NFS-mounted filesystem where 458338032Speter the local system says that giveaway is denied but it is 458438032Speter actually permitted. I believe this to be a very small set 458538032Speter of cases. If in doubt, do not point :include: aliases at 458638032Speter NFS-mounted filesystems. 458738032Speter SECURITY: When setting a numeric group id using the RunAsUser option 458838032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 458938032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 459038032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 459138032Speter The user id was still set properly. Problem noted by Uli 459238032Speter Pralle of the Technical University of Berlin. 459338032Speter Save the initial gid set for use when checking for if the 459438032Speter PrivacyOptions=restrictmailq option is set.

Patch 460138032Speter from Theo de Raadt. 460238032Speter The "Message is too large" error didn't successfully bounce the error 460338032Speter back to the sender.

Note that this should really 463538032Speter be fixed in the zone file for the domain. Problem noted by 463638032Speter Joe Rhett of Navigist, Inc. 463738032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 463838032Speter the message as having been tried; otherwise the next queue 463938032Speter run will not realize that this is a second attempt and will 464038032Speter retry immediately. Problem noted by Bryan Costales of 464138032Speter Mercury Mail. 464238032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 464338032Speter will be run until the later setting of the clock is reached. 464438032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 464538032Speter Morgan Stanley. 464638032Speter If the load average rises above the cutoff threshold (above which 464738032Speter sendmail will not process the queue at all) during a queue 464838032Speter run, abort the queue run immediately. Problem noted by 464938032Speter Bryan Costales of Mercury Mail. 465038032Speter The variable queue processing algorithm (based on the message size, 465138032Speter number of recipients, message precedence, and job age) was 465238032Speter non-functional -- either the entire queue was processed or 465338032Speter none of the queue was processed. The updated algorithm 465438032Speter does no queue run if a single recipient zero size job will 465538032Speter not be run. 465638032Speter If there is a fatal ("panic") message that will cause sendmail to 465738032Speter die immediately, never hold the error message for future 465838032Speter printing. 465938032Speter Force ErrorMode=print in -bt mode so that all errors are printed 466038032Speter regardless of the setting of the ErrorMode option in the 466138032Speter configuration file. Patch from Gregory Neil Shapiro. 466238032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 466338032Speter routine available in one of the libraries. Use it in conf.h. 466438032Speter The -m (match only) flag now works on host class maps. 466538032Speter If class hash or btree maps are rebuilt, sendmail will now detect 466638032Speter this and reopen the map. Previously, they could give 466738032Speter erroneous results during a single message processing 466838032Speter (but would recover when the next message was received). 466938032Speter Don't delete zero length queue files when doing queue runs until the 467038032Speter files are at least ten minutes old. This avoids a potential 467138032Speter race condition: the creator creates the qf file, getting back 467238032Speter a file descriptor. The queue runner locks it and deletes it 467338032Speter because it is zero length. The creator then writes the 467438032Speter descriptor that is now for a disconnected file, and the 467538032Speter job goes away. Based on a suggestion by Bryan Costales. 467638032Speter When determining the "validated" host name ($_ macro), do a forward 467738032Speter (A) DNS lookup on the result of the PTR lookup and compare 467838032Speter results. If they differ or if the PTR lookup fails, tag the 467938032Speter address as "may be forged". 468038032Speter Log null connections (i.e., hosts that connect but do not do any 468138032Speter substantive activity on the connection before disconnecting; 468238032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 468338032Speter Always permit "writes" to /dev/null regardless of the link count. 468438032Speter This is safe because /dev/null is special cased, and no open 468538032Speter or write is ever actually attempted. Patch from Villy Kruse 468638032Speter of TwinCom. 468738032Speter If a message cannot be sent because of a 552 (exceeded storage 468838032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 468938032Speter was given, don't return the body in the bounce, since there 469038032Speter is a very good chance that the message will double-bounce. 469138032Speter Fix possible line truncation if a quoted-printable had an =00 escape 469238032Speter in the body. Problem noted by Charles Karney of the Princeton 469338032Speter Plasma Physics Laboratory. 469438032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 469538032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 469638032Speter Institute. 469738032Speter The MaxDaemonChildren option wasn't applying to queue runs as 469838032Speter documented. Note that this increases the potential denial 469938032Speter of service problems with this option: an attacker can 470038032Speter connect many times, and thereby lock out queue runs as well 470138032Speter as incoming connections. If you use this option, you should 470238032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 470338032Speter to avoid this attack. Failure to limit noted by Matthew 470438032Speter Dillon of BEST Internet Communications. 470538032Speter Always give a message in newaliases if alias files cannot be 470638032Speter opened instead of failing silently. Suggested by Gregory 470738032Speter Neil Shapiro. This change makes the code match the O'Reilly 470838032Speter book (2nd edition). 470938032Speter Some older versions of the resolver could return with h_errno == -1 471038032Speter if no name server could be reached, causing mail to bounce 471138032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 471238032Speter John Beck of SunSoft. 471338032Speter If a :include: file is owned by a user that does not have an entry 471438032Speter in the passwd file, sendmail could dereference a null pointer. 471538032Speter Problem noted by Satish Mynam of Sun Microsystems. 471638032Speter Take precautions to make sure that the SMTP protocol cannot get out 471738032Speter of sync if (for example) an alias file cannot be opened. 471838032Speter Fix a possible race condition that can cause a SIGALRM to come in 471938032Speter immediately after a SIGHUP, causing the new sendmail to die. 472038032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 472138032Speter from Villy Kruse of TwinCom. 472238032Speter Ignore improperly formatted SMTP reply codes. Previously these were 472338032Speter partially processed, which could cause confusing error 472438032Speter returns. 472538032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 472638032Speter on some architectures. 472738032Speter Portability: 472838032Speter A/UX: from Jim Jagielski of NASA/GSFC. 472938032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 473038032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 473138032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 473238032Speter defined. Problem reported by A Sun of the University 473338032Speter of Washington. 473438032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 473538032Speter the system rather than guessing at compile time. 473638032Speter Patch contributed by John Beck of Sun Microsystems. 473738032Speter Intel Paragon: from Wendy Lin of Purdue University. 473838032Speter GNU Hurd: from Miles Bader of the GNU project. 473938032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 474038032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 474138032Speter Unfortunately releasing them opens a race condition, 474238032Speter but there appears to be no fix for this. Patch from 474338032Speter Gregory Neil Shapiro. 474438032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 474538032Speter Solaris: a bug in strcasecmp caused characters with the 474638032Speter high order bit set to apparently randomly match 474738032Speter letters -- for example, $| (0233) matches "i" and "I". 474838032Speter Problem noted by John Gregson of the University of 474938032Speter Cambridge. 475038032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 475138032Speter Kari Hurtta. 475238032Speter IRIX 6.x: Create Makefiles for systems that claim to be 475338032Speter IRIX64 but are 6.2 or higher (so use the regular 475438032Speter IRIX Makefile). 475538032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 475638032Speter Problem noted by Eric Hagberg of Morgan Stanley. 475738032Speter CONFIG: Some canonification was still done for UUCP-like addresses 475838032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 475938032Speter Brian Candler. 476038032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 476138032Speter local names as local. Problem noted by Jeff Polk of BSDI; 476238032Speter fix provided by Gregory Neil Shapiro. 476338032Speter CONFIG: The "local:user" syntax entries in mailertables and other 476438032Speter "mailer:user" syntax locations returned an incorrect value 476538032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 476638032Speter CONFIG: Retain "+detail" information when forwarding mail to a 476738032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 476838032Speter Guenther of Gustavus Adolphus College. 476938032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 477038032Speter rules are the same as for aliasing. Based on a patch from 477138032Speter Gregory Neil Shapiro. 477238032Speter CONFIG: Break up parsing rules into several pieces; this should 477338032Speter have no functional change in this release, but makes it 477438032Speter possible to have better anti-spam rulesets in the future. 477538032Speter CONFIG: Disallow double dots in host names to avoid having the 477638032Speter HostStatusDirectory store status under the wrong name. 477738032Speter In some cases this can be used as a denial-of-service attack. 477838032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 477938032Speter Gregory Neil Shapiro. 478038032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 478138032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 478238032Speter don't include From_, and convert to 8-bit). Suggestions 478338032Speter from Kimmo Suominen and Roderick Schertler. 478464562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 478538032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 478638032Speter was specified, even when it wasn't. 478738032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 478838032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 478938032Speter "slip in" a symbolic link between the lstat(2) call and the 479038032Speter exclusive open. This is only a problem on System V derived 479138032Speter systems that allow an exclusive create on files that are 479238032Speter symbolic links pointing nowhere. 479338032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 479438032Speter not reset back to root, which on some systems would cause 479538032Speter later mailboxes to fail. Also, any partial message would 479638032Speter not be truncated, which could result in repeated deliveries. 479738032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 479838032Speter developers). 479938032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 480038032Speter change to the sendmail map code was made in 8.8.3. Problem 480138032Speter noted by Gregory Neil Shapiro. 480238032Speter MAKEMAP: Give warnings on file problems such as map files that are 480390792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 480438032Speter often run as root and hence has the potential for the same 480538032Speter sorts of problems as alias rebuilds. 480638032Speter MAKEMAP: Change compilation so that it will link properly on 480738032Speter NEXTSTEP. 480838032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 480938032Speter Accept an optional list of arguments following the server 481038032Speter name for the ETRN arguments to use (instead of $=w). Other 481138032Speter miscellaneous bug fixes. From Christian von Roques via 481238032Speter John Beck of Sun Microsystems. 481338032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 481438032Speter Perl script converts GECOS information in the /etc/passwd 481538032Speter file into aliases, allowing for faster access to full name 481638032Speter lookups; it is also clever about adding aliases (to root) 481738032Speter for system accounts. 481838032Speter NEW FILES: 481938032Speter src/safefile.c 482038032Speter cf/ostype/gnuhurd.m4 482138032Speter cf/ostype/irix6.m4 482238032Speter contrib/passwd-to-alias.pl 482338032Speter src/Makefiles/Makefile.IRIX64.6.1 482438032Speter src/Makefiles/Makefile.IRIX64.6.x 482538032Speter RENAMED FILES: 482638032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 482738032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 482838032Speter 482964562Sgshapiro8.8.5/8.8.5 1997/01/21 483038032Speter SECURITY: Clear out group list during startup. Without this, sendmail 483138032Speter will continue to run with the group permissions of the caller, 483238032Speter even if RunAsUser is specified. 483338032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 483438032Speter to any known attack, but it's best to be conservative. 483538032Speter Suggested by Peter Wemm of DIALix. 483638032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 483738032Speter security implications. Patch from Alex Garthwaite of the 483838032Speter University of Pennsylvania. 483938032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 484038032Speter would truncate the address after "Full". Although the -f 484138032Speter syntax is incorrect (since it is in the envelope, it 484238032Speter shouldn't have comments and full names), the failure mode 484338032Speter was unnecessarily awful. 484438032Speter Fix a possible null pointer dereference when converting 8-bit data 484538032Speter to a 7-bit format. Problem noted by Jim Hutchins of 484638032Speter Sandia National Labs and David James of British Telecom. 484738032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 484838032Speter runs. Although this really shouldn't be used (F=9 is for 484938032Speter final delivery only, and using it on an SMTP mailer makes 485038032Speter it possible for a message to be converted from 8->7->8->7 485138032Speter bits several times), it shouldn't have failed with a syserr. 485238032Speter Problem noted by Eric Hagberg of Morgan Stanley. 485338032Speter _Really_ fix the multiple :maildrop code in the user database 485438032Speter module. Patch from Roy Mongiovi of Georgia Tech. 485538032Speter Let F lines in the configuration file actually read root-only 485638032Speter files if the configuration file is safe. Based on a 485738032Speter patch from Keith Reynolds of SCO. 485838032Speter ETRN followed by QUIT would hold the connection open until the queue 485938032Speter run completed. Problem noted by Truck Lewis of TDK 486038032Speter Semiconductor Corp. 486138032Speter It turns out that despite the documentation, the TCP wrappers library 486238032Speter does _not_ log rejected connections. Do the logging ourselves. 486338032Speter Problem noted by Fletcher Mattox of the University of Texas 486438032Speter at Austin. 486538032Speter If sendmail finds a qf file in its queue directory that is an unknown 486638032Speter version (e.g., when backing out to an old version), the 486738032Speter error is reported on every queue run. Change it to only 486838032Speter give the error once (and rename the qf => Qf). Patch from 486938032Speter William A. Gianopoulos of Raytheon Company. 487038032Speter Start a new session when doing background delivery; currently it 487138032Speter ignored signals but didn't start a new signal, that caused 487238032Speter some problems if a background process tried to send mail 487338032Speter under certain circumstances. Problem noted by Eric Hagberg 487438032Speter of Morgan Stanley; fix from Kari Hurtta. 487538032Speter Simplify test for skipping a queue run to just check if the current 487638032Speter load average is >= the queueing load average. Previously 487738032Speter the check factored in some other parameters that caused it 487838032Speter to essentially never skip the queue run. Patch from Bryan 487938032Speter Costales. 488038032Speter If the SMTP server is running in "nullserver" mode (that is, it is 488138032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 488238032Speter (25) commands; this helps prevent a bad guy from putting 488338032Speter you into a tight loop as a denial-of-service attack. Based 488438032Speter on an e-mail conversation with Brad Knowles of AOL. 488538032Speter Slow down when too many "light weight" commands have been issued; 488638032Speter this helps prevent a class of denial-of-service attacks. 488738032Speter The current values and defaults are: 488838032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 488938032Speter MAXHELOCOMMANDS 3 HELO, EHLO 489038032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 489138032Speter MAXETRNCOMMANDS 8 ETRN 489238032Speter These will probably be configurable in a future release. 489338032Speter On systems that have uid_t typedefed to be an unsigned short, programs 489438032Speter that had the F=S flag and no U= equate would be invoked with 489538032Speter the real uid set to 65535 rather than being left unchanged. 489638032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 489738032Speter by Steve Hubert of the University of Washington, Seattle. 489838032Speter Mail that was Quoted-Printable encoded and had a soft line break on 489938032Speter the last line (i.e., an incomplete continuation) had the last 490038032Speter line dropped. Since this appears to be illegal it isn't 490138032Speter clear what to do with it, but flushing the last line seems 490238032Speter to be a better "fail soft" approach. Based on a patch from 490338032Speter Eric Hagberg. 490438032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 490538032Speter bogus HELO command still causes the "Polite people say HELO 490638032Speter first" error message. Problem pointed out by Chris Thomas 490738032Speter of UCLA; patch from John Beck of SunSoft. 490838032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 490971345Sgshapiro in PrivacyOptions.

Problem noted by Ronan KERYELL 494938032Speter of Centre de Recherche en Informatique de l'�cole Nationale 495038032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 495138032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 495238032Speter such as LUSER_RELAY. This change permits the following 495338032Speter syntaxes: ``local:'' will send to the same user on the 495438032Speter local machine (e.g., in a mailertable entry for "host", 495538032Speter ``local:'' will cause an address addressed to user@host to 495638032Speter go to user on the local machone). ``local:user'' will send 495738032Speter to the named user on the local machine. ``local:user@host'' 495838032Speter is equivalent to ``local:user'' (the host is ignored). In 495938032Speter all cases, the original user@host is passed in $@ (i.e., the 496038032Speter detail information). Inspired by a report from Michael Fuhr. 496138032Speter CONFIG: Strip quotes from the first word of an "error:" host 496238032Speter indication. This lets you set (for example) the LUSER_RELAY 496338032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 496438032Speter of the \" so that the resulting string is properly quoted. 496538032Speter Problem noted by Gregory Neil Shapiro of WPI. 496638032Speter OP.ME: documentation was inconsistent about whether sendmail did a 496738032Speter NOOP or a RSET to probe the connection (it does a RSET). 496838032Speter Inconsistency noted by Deeran Peethamparam. 496938032Speter OP.ME: insert additional blank pages so it will print properly on 497038032Speter a duplex printer.

The solution is to disallow any 497738032Speter files that have hard links -- this will affect .forward, 497838032Speter :include:, and output files. Problem noted by Terry 497938032Speter Kyriacopoulos of Interlog Internet Services. As a 498038032Speter workaround, set UnsafeGroupWrites -- always a good idea. 498138032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 498238032Speter is, it is possible to do a denial-of-service attack on 498338032Speter MX hosts that rely on the use of the null MX list. There 498438032Speter is no danger if you have this option turned off (the default). 498538032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 498638032Speter unsafe. I know of no specific attack against this, although 498738032Speter a denial-of-service attack is probably possible, but in theory 498838032Speter you should not be able to safely tweak anything that affects 498938032Speter the permissions that are used when mail is delivered. 499038032Speter Purgestat could go into an infinite loop if one of the host status 499138032Speter directories somehow became empty. Problem noted by Roy 499238032Speter Mongiovi of Georgia Tech. 499338032Speter Processes got "lost" when counting children due to a race condition. 499438032Speter This caused "proc_list_probe: lost pid" messages to be logged. 499538032Speter Problem noted by several people. 499638032Speter On systems with System V SIGCLD child signal semantics (notably AIX 499738032Speter and HP-UX), mail transactions would print the message "451 499838032Speter SMTP-MAIL: lost child: No child processes". Problem noted 499938032Speter by several people. 500038032Speter Miscellaneous compiler warnings on picky compilers (or when setting 500138032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 500238032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 500338032Speter not be persistent between runs, since they are based on the 500438032Speter message rather than the host. Problem noted by Matt Dillon 500538032Speter of Best Internet Communications. 500638032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 500738032Speter of NCR (a.k.a., AT&T Global Information Solutions). 500838032Speter Avoid the possibility of having a child daemon run to completion 500938032Speter (including closing the SMTP socket) before the parent has 501038032Speter had a chance to close the socket; this can cause the parent 501138032Speter to hang for a long time waiting for the socket to drain. 501238032Speter Patch from Don Lewis of TDK Semiconductor. 501338032Speter If the fork() failed in a queue run, the queue runners would not be 501438032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 501538032Speter Some error conditions in ETRN could cause output without an SMTP 501638032Speter status code. Problem noted by Don Lewis. 501738032Speter Multiple :maildrop addresses in the user database didn't work properly. 501838032Speter Patch from Roy Mongiovi of Georgia Tech. 501938032Speter Add ".db" automatically onto any user database spec that does not 502038032Speter already have it; this is for consistency with makemap, the 502138032Speter K line, and the documentation. Inconsistency pointed out 502238032Speter by Roy Mongiovi. 502338032Speter Allow sendmail to be properly called in nohup mode. Patch from 502438032Speter Kyle Jones of UUNET. 502538032Speter Change ETRN to ignore but still update host status files; previously 502638032Speter it would ignore them and not save the updated status, which 502738032Speter caused stale information to be maintained. Based on a patch 502838032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 502938032Speter ETRN ignore the MinQueueAge option. 503038032Speter Patch long term host status to recover more gracefully from an empty 503138032Speter host status file condition. Patch from NAKAMURA Motonori 503238032Speter of Kyoto University. 503338032Speter Several patches to signal handling code to fix potential race 503438032Speter conditions from Don Lewis. 503538032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 503638032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 503738032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 503838032Speter compile flag; use NETINET instead. Solution based on a 503938032Speter patch from Bryan Costales. 504038032Speter PORTABILITY FIXES: 504138032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 504238032Speter /etc/security/passwd file when called as root. This 504338032Speter is very slow on some systems. To speed it up, use the 504438032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 504538032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 504638032Speter SCO 5.x: include -lprot in the Makefile.

Problem 508538032Speter noted by Eric Bishop of Virginia Tech. 508638032Speter When doing text-based host canonification (typically /etc/hosts 508738032Speter lookup), a null host name would match any /etc/hosts entry 508838032Speter with space at the end of the line. Problem noted by Steve 508938032Speter Hubert of the University of Washington, Seattle. 509038032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 509138032Speter Problem reported by Tom Smith of Digital Equipment Corp. 509238032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 509338032Speter size PACKETSZ (512) is not sufficient for some nameserver 509438032Speter answers containing very many resource records. The resolver 509538032Speter may also switch to TCP and retry if it detects UDP packet 509638032Speter overflow. Also, allow for the fact that the resolver 509738032Speter routines res_query and res_search return the size of the 509838032Speter *un*truncated answer in case the supplied answer buffer it 509938032Speter not big enough to accommodate the entire answer. Patch from 510038032Speter Eric Wassenaar. 510138032Speter Improvements to MaxDaemonChildren code. If you think you have too 510238032Speter many children, probe the ones you have to verify that they 510338032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 510438032Speter Also, do this probe before growing the vector of children 510538032Speter pids; this previously caused the vector to grow indefinitely 510638032Speter due to a race condition. Problem reported by Kyle Jones of 510738032Speter UUNET. 510838032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 510938032Speter O_EXLOCK to zero; this fools the map compilation code into 511038032Speter thinking that it can avoid race conditions by locking on open. 511138032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 511238032Speter Leif Erlingsson of Data Lege. 511338032Speter Always call res_init() on startup (if compiled in, of course) to 511438032Speter allow the sendmail.cf file to tweak resolver flags; without 511538032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 511638032Speter Andrew Sun of Merrill Lynch. 511738032Speter Improvements to host status printing code. Suggested by Steve Hubert 511838032Speter of the University of Washington, Seattle. 511938032Speter Change MinQueueAge option processing to do the check for the job age 512038032Speter when reading the queue file, rather than at the end; this 512138032Speter avoids parsing the addresses, which can do DNS lookups. 512238032Speter Problem noted by John Beck of InReference, Inc. 512338032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 512438032Speter properly escaped. Problem noted by Peter Nilsson of the 512538032Speter University of Linkoping. 512638032Speter In some cases, sendmail would retain root permissions during queue 512738032Speter runs even if RunAsUser was set. Problem noted by Mark 512838032Speter Thomas of Mark G.

If this option is null (as 520938032Speter opposed to undefined) it can cause "null signature" syserrs 521038032Speter on illegal host names. 521138032Speter If a Base64 encoded text/plain message has no trailing newline in 521238032Speter the encoded text, conversion back to 8 bits will drop the 521338032Speter final line. Problem noted by Pierre David. 521438032Speter If running with a RunAsUser, sendmail would give bogus "cannot 521538032Speter setuid" (or seteuid, or setreuid) messages on some systems. 521638032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 521738032Speter Always print error messages in -bv mode -- previously, -bv would 521838032Speter be absolutely silent on errors if the error mode was sent 521938032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 522038032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 522138032Speter term host status. This is necessary because it is common 522238032Speter to do this when you know a host has just come back up. 522338032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 522438032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 522538032Speter University of Leicester. 522638032Speter If a service (such as NIS) is specified as the last entry in the 522738032Speter service switch, but that service is not compiled in, sendmail 522838032Speter would return a temporary failure when an entry was not found 522938032Speter in the map. This caused the message to be queued instead of 523038032Speter bouncing immediately.

In order to avoid 527438032Speter trashing memory, the buffer for all names has only been 527538032Speter slightly increased in size, to 12.8K from 10.2K -- this means 527638032Speter that if a single name had 100 MX records, the average size 527738032Speter of those records could not exceed 128 bytes.

Berkeley. 528138032Speter Print q_statdate and q_specificity in address structure debugging 528238032Speter printout. 528338032Speter Expand MCI structure flag bits for debugging output. 528438032Speter Support IPv6-style domain literals, which can have colons between 528538032Speter square braces. 528638032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 528738032Speter this is an attempt to track down a bug that one person seems 528838032Speter to be having (it may be a Solaris bug!). 528938032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 529038032Speter this caused the NOTIFY info to sometimes be lost. Problem 529138032Speter pointed out by Claus Assmann of the 529238032Speter Christian-Albrechts-University of Kiel. 529338032Speter The statistics gathered in the sendmail.st file were too high; in 529438032Speter some cases failures (e.g., user unknown or temporary failure) 529538032Speter would count as a delivery as far as the statistics were 529638032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 529738032Speter Systems that don't have flock() would not send split envelopes in 529838032Speter the initial run. Problem pointed out by Leonard Zubkoff of 529938032Speter Dandelion Digital. 530038032Speter Move buffer overflow checking -- these primarily involve distrusting 530138032Speter results that may come from NIS and DNS. 530238032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 530338032Speter include <paths.h> and hence had the wrong pathnames for a few 530438032Speter things like /var/tmp. Reported by Matthew Green. 530538032Speter Conditions were reversed for the Priority: header, resulting in all 530638032Speter values being interpreted as non-urgent except for non-urgent, 530738032Speter which was interpreted as normal. Patch from Bryan Costales. 530838032Speter The -o (optional) flag was being ignored on hash and btree maps 530938032Speter since 8.7.2. Fix from Bryan Costales. 531038032Speter Content-Types listed in class "q" will always be encoded as 531138032Speter Quoted-Printable (or more accurately, will never be encoded 531238032Speter as base64). The class can have primary types (e.g., "text") 531338032Speter or full types (e.g., "text/plain"). Based on a suggestion by 531438032Speter Marius Olafsson of the University of Iceland. 531538032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 531638032Speter dialogue) so it can be passed to programs in mailers. 531738032Speter Define ${bodytype} to be the body type (from the -B flag or the 531838032Speter BODY= ESMTP parameter) so it can be passed to programs in 531938032Speter mailers. 532038032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 532138032Speter flag is set in the mailer descriptor. Suggested by John 532238032Speter Myers of CMU. 532338032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 532438032Speter The command takes a host name; data for that host is 532538032Speter immediately (and asynchronously) flushed. Because this shares 532638032Speter the -qR implementation, other hosts may be attempted, but 532738032Speter there should be no security implications. Implementation 532838032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 532938032Speter Add three new command line flags to pass in DSN parameters: -V envid 533038032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 533138032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 533238032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 533338032Speter that the -N flag applies to all recipients; there is no way 533438032Speter to specify per-address notifications on the command line, 533538032Speter nor is there an equivalent for the ORCPT= per-address 533638032Speter parameter. 533738032Speter Restore LogLevel option to be safe (it can only be increased); 533838032Speter apparently I went into paranoid mode between 8.6 and 8.7 533938032Speter and made it unsafe. Pointed out by Dabe Murphy of the 534038032Speter University of Maryland. 534138032Speter New logging on log level 15: all SMTP traffic. Patches from 534238032Speter Andrew Gross of San Diego Supercomputer Center. 534338032Speter NetInfo property value searching code wasn't stopping when it found 534438032Speter a match. This was causing the wrong values to be found (and 534538032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 534638032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 534738032Speter out by Bill Wisner of Electronics for Imaging that you can't 534838032Speter use the bracket address form for the MAIL_HUB macro, since 534938032Speter that causes the brackets to remain in the envelope recipient 535038032Speter address used for delivery. The simple fix (stripping off the 535138032Speter brackets in the config file) breaks the use of IP literal 535238032Speter addresses. This flag will solve that problem. 535338032Speter Add MustQuoteChars option. This is a list of characters that must 535438032Speter be quoted if they are found in the phrase part of an address 535538032Speter (that is, the full name part). The characters @,;:\()[] are 535638032Speter always in this list and cannot be removed. The default is 535738032Speter this list plus . and ' to match RFC 822. 535838032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 535938032Speter that do not include a host name for back compatibility with 536038032Speter some stupid SMTP clients. Setting this violates RFC 1123 536138032Speter section 5.2.5. 536238032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 536338032Speter rejecting connections if it has more than this many 536438032Speter outstanding children accepting mail. Note that you may 536538032Speter see more processes than this because of outgoing mail; this 536638032Speter is for incoming connections only. 536738032Speter Add ConnectionRateThrottle option. If set to a positive value, the 536838032Speter number of incoming SMTP connections that will be permitted 536938032Speter in a single second is limited to this number. Connections are 537038032Speter not refused during this time, just deferred. The intent is to 537138032Speter flatten out demand so that load average limiting can kick in. 537238032Speter It is less radical than MaxDaemonChildren, which will stop 537338032Speter accepting connections even if all the connections are idle 537438032Speter (e.g., due to connection caching). 537538032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 537638032Speter specifies how long cached information about the state of a 537738032Speter host will be kept before they are considered stale and the 537838032Speter host is retried. If you are using persistent host status 537938032Speter (i.e., the HostStatusDirectory option is set) this will apply 538038032Speter between runs; otherwise, it applies only within a single queue 538138032Speter run and hence is useful only for hosts that have large queues 538238032Speter that take a very long time to run. 538338032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 538438032Speter into being a single line even if they had newlines in them 538538032Speter when read. This is to get around a botch in Lotus Notes. 538638032Speter Text class maps were totally broken -- if you ever retrieved the last 538738032Speter item in a table it would be truncated. Problem noted by 538838032Speter Gregory Neil Shapiro of WPI. 538938032Speter Extend the lines printed by the mailq command (== the -bp flag) when 539038032Speter -v is given to 120 characters; this allows more information 539138032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 539238032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 539338032Speter this was treated as end-of-input. Problem noted by Bryan 539438032Speter Costales. 539538032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 539638032Speter to the queue file. Fix from John Hughes of Atlantic 539738032Speter Technologies, Inc. 539838032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 539938032Speter if this happens in a queue run it can cause nasty delays. 540038032Speter Problem noted by Mark Horton of AT&T. 540138032Speter If userdb entries pointed to userdb entries, and there were multiple 540238032Speter values for a given key, the database cursor would get 540338032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 540438032Speter of Georgia Tech. Fixed by reading all the values and creating 540538032Speter a comma-separated list; thus, the -v output will be somewhat 540638032Speter different for this case. 540738032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 540838032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 540938032Speter of Stanford University. 541038032Speter When envelopes were split due to aliases with owner- aliases, and 541138032Speter there was some error on one of the lists, more than one of 541238032Speter the owners would get the message. Problem pointed out by 541338032Speter Roy Mongiovi of Georgia Tech. 541438032Speter Detect excessive recursion in macro expansions, e.g., $X defined 541538032Speter in terms of $Y which is defined in terms of $X. Problem 541638032Speter noted by Bryan Costales; patch from Eric Wassenaar. 541738032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 541838032Speter some cases get trashed causing bogus From_ lines. Fix from 541938032Speter Kyle Jones of UUNET. 542038032Speter When doing load average initialization, if the nlist call for avenrun 542138032Speter failed, the second and subsequent lookups wouldn't notice 542238032Speter that fact causing bogus load averages to be returned. Noted 542338032Speter by Casper Dik of Sun Holland. 542438032Speter Fix problem with incompatibility with some versions of inet_aton that 542538032Speter have changed the return value to unsigned, so a check for an 542638032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 542738032Speter This could cause mail to addresses such as [foo.com] to bounce 542838032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 542938032Speter Pasteur Institute. 543038032Speter DSNs were inconsistent if a failure occurred during the DATA phase 543138032Speter rather than the RCPT phase: the Action: would be correct, but 543238032Speter the detailed status information would be wrong. Problem noted 543338032Speter by Bob Snyder of General Electric Company. 543438032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 543538032Speter that this is the initial MUA->MTA submission. The flag current 543638032Speter does nothing, but in future releases (when MUAs start using 543738032Speter these flags) it will probably turn on things like DNS 543838032Speter canonification. 543938032Speter Default end-of-line string (E= specification on mailer [M] lines) 544038032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 544138032Speter mailers. 544238032Speter Change the internal definition for the *file* and *include* mailers 544338032Speter to have $u in the argument vectors so that they aren't 544438032Speter misinterpreted as SMTP mailers and thus use \r\n line 544538032Speter termination. This will affect anyone who has redefined 544638032Speter either of these in their configuration file. 544738032Speter Don't assume that IDENT servers close the connection after a query; 544838032Speter responses can be newline terminated. From Terry Kennedy of 544938032Speter St. Peter's College. 545038032Speter Avoid core dumps on erroneous configuration files that have 545138032Speter $#mailer with nothing following. From Bryan Costales. 545238032Speter Avoid null pointer dereference with high debug values in unlockqueue. 545338032Speter Fix from Randy Martin of Clemson University. 545438032Speter Fix possible buffer overrun when expanding very large macros. Fix 545538032Speter from Kyle Jones of UUNET. 545638032Speter After 25 EXPN or VRFY commands, start pausing for a second before 545738032Speter processing each one. This avoids a certain form of denial 545838032Speter of service attack. Potential attack pointed out by Bryan 545938032Speter Costales. 546038032Speter Allow new named (not numbered!) config file rules to do validity 546138032Speter checking on SMTP arguments: check_mail for MAIL commands and 546238032Speter check_rcpt for RCPT commands. These rulesets can do anything 546338032Speter they want; their result is ignored unless they resolve to the 546438032Speter $#error mailer, in which case the indicated message is printed 546538032Speter and the command is rejected. Similarly, the check_compat 546638032Speter ruleset is called before delivery with "from_addr $| to_addr" 546738032Speter (the $| is a meta-symbol used to separate the two addresses); 546838032Speter it can give a "this sender can't send to this recipient" 546938032Speter notification. Note that this patch allows $| to stand alone 547038032Speter in rulesets. 547138032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 547238032Speter that have the name, IP address, and port number (respectively) 547338032Speter of the SMTP client (that is, the entity at the other end of 547438032Speter the connection. These can be used in (e.g.) check_rcpt to 547538032Speter verify that someone isn't trying to relay mail through your 547638032Speter host inappropriately. Be sure to use the deferred evaluation 547738032Speter form, for example $&{client_name}, to avoid having these bound 547838032Speter when sendmail reads the configuration file. 547938032Speter Add new config file rule check_relay to check the incoming connection 548038032Speter information. Like check_compat, it is passed the host name 548138032Speter and host address separated by $| and can reject connections 548238032Speter on that basis. 548338032Speter Allow IDA-style recursive function calls. Code contributed by Mark 548438032Speter Lovell and Paul Vixie. 548538032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 548638032Speter a virtual UUCP address using either a domain address or the $k 548738032Speter macro. Based on code contributed by Mark Lovell and Paul 548838032Speter Vixie. 548938032Speter Add Stanford LDAP map. Requires special libraries that are not 549038032Speter included with sendmail. Contributed by Booker C. Bense 549138032Speter <bbense@networking.stanford.edu>; contact him for support. 549238032Speter See also the src/READ_ME file. 549338032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 549438032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 549538032Speter only for debugging deep bits of code where it is important to 549638032Speter distinguish between the single-character metasymbol $+ and the 549738032Speter two characters $, +. 549838032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 549938032Speter debug_dumpstate. 550038032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 550138032Speter files that are group writable are considered "unsafe" -- that 550238032Speter is, programs and files referenced from such files are not 550338032Speter valid recipients. 550438032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 550538032Speter name that was not in DNS or was a domain-literal. Problem 550638032Speter noted by Tom May. 550738032Speter Change the introduction to error messages to more clearly delineate 550838032Speter permanent from temporary failures; if both existed in a 550938032Speter single message it could be confusing. Suggested by John 551038032Speter Beck of InReference, Inc. 551138032Speter The IngoreDot (i) option didn't work for lines that were terminated 551238032Speter with CRLF. Problem noted by Ted Stockwell of Secure 551338032Speter Computing Corporation. 551438032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 551538032Speter message headers. Problem reported by Matt Dillon of Best 551638032Speter Internet Communications. 551738032Speter Check for bogus characters in the 0200-0237 range; since these are 551838032Speter used internally, very strange errors can occur if those 551938032Speter characters appear in headers. Problem noted by Anders Gertz 552038032Speter of Lysator. 552138032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 552238032Speter recipient mailer has the F=9 flag set, and only works on 552338032Speter text/plain body types. Code contributed by Marius Olafsson 552438032Speter of the University of Iceland. 552538032Speter Special case "postmaster" name so that it is always treated as lower 552638032Speter case in alias files regardless of configuration settings; 552738032Speter this prevents some potential problems where "Postmaster" or 552838032Speter "POSTMASTER" might not match "postmaster". In most cases 552938032Speter this change is a no-op. 553038032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 553138032Speter Costales. 553238032Speter The -a map flag was ignored for dequote maps. Problem noted by 553338032Speter Bryan Costales. 553438032Speter Fix core dump when a lookup of a class "prog" map returns no 553538032Speter response. Patch from Bryan Costales. 553638032Speter Log instances where sendmail is deferring or rejecting connections 553738032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 553838032Speter Include port number in process title for network daemons. Suggested 553938032Speter by Kyle Jones of UUNET. 554038032Speter Send ``double bounces'' (errors that occur when sending an error 554138032Speter message) to the address indicated in the DoubleBounceAddress 554238032Speter option (default: postmaster). Previously they were always 554338032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 554438032Speter Add new mode, -bD, that acts like -bd in all respects except that 554538032Speter it runs in foreground. This is useful for using with a 554638032Speter wrapper that "watches" system services. Suggested by Kyle 554738032Speter Jones of UUNET. 554838032Speter Fix botch in spacing around (parenthesized) comments in addresses 554938032Speter when the comment comes before the address. Patch from 555038032Speter Motonori Nakamura of Kyoto University. 555138032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 555238032Speter that are being bounced to postmaster, rather than "Returned 555338032Speter mail". This permits the person who is postmaster more 555438032Speter easily determine what messages are to their role as 555538032Speter postmaster versus bounces to mail they actually sent. Based 555638032Speter on a suggestion by Motonori Nakamura. 555738032Speter Add new value "time" for QueueSortOrder option; this causes the queue 555838032Speter to be sorted strictly by the time of submission. Note that 555943730Speter this can cause very bad behavior over slow lines (because 556038032Speter large jobs will tend to delay small jobs) and on nodes with 556138032Speter heavy traffic (because old things in the queue for hosts that 556238032Speter are down delay processing of new jobs). Also, this does not 556338032Speter guarantee that jobs will be delivered in submission order 556438032Speter unless you also set DeliveryMode=queue. In general, it should 556538032Speter probably only be used on the command line, and only in 556638032Speter conjunction with -qRhost.domain. In fact, there are very few 556738032Speter cases where it should be used at all. Based on an 556838032Speter implementation by Motonori Nakamura. 556938032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 557038032Speter the same manner as other rulesets. Previously a temporary 557138032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 557238032Speter of Stanford University. 557338032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 557438032Speter 5yz (permanent failure) code. The next MX host will still be 557538032Speter tried if the connection cannot be opened in the first place 557638032Speter or if the MAIL command returns a 4yz (temporary failure) code. 557738032Speter (It's hard to know what to do here, since neither RFC 974 nor 557838032Speter RFC 1123 specify when to proceed to the next MX host.) 557938032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 558038032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 558138032Speter This causes map lookups that get a temporary failure (e.g., 558238032Speter name server failure) to _not_ defer the delivery of the 558338032Speter message. This should only be used if your configuration file 558438032Speter is prepared to do something sensible in this case. Based on 558538032Speter an idea by Gregory Shapiro of WPI. 558638032Speter Fix problem finding network interface addresses. Patch from 558738032Speter Motonori Nakamura. 558838032Speter Don't reject qf entries that are not owned by your effective uid if 558990792Sgshapiro you are not running set-user-ID; this makes management of 559080785Sgshapiro certain kinds of firewall setups difficult. Patch 559180785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 559238032Speter Add persistent host status. This keeps the information normally 559338032Speter maintained within a single queue run in disk files that are 559438032Speter shared between sendmail instances. The HostStatusDirectory 559538032Speter is the directory in which the information is maintained. If 559638032Speter not set, persistent host status is turned off. If not a full 559738032Speter pathname, it is relative to the queue directory. A common 559838032Speter value is ".hoststat". 559938032Speter There are also two new operation modes: 560038032Speter * -bh prints the status of hosts that have had recent 560138032Speter connections. 560238032Speter * -bH purges the host statuses. No attempt is made to save 560338032Speter recent status information. 560438032Speter This feature was originally written by Paul Vixie of Vixie 560538032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 560638032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 560738032Speter with my insistence that things fit cleanly into the V8 560838032Speter framework is gratefully appreciated. 560938032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 561038032Speter operate). Avoids letting two sendmails on the local machine 561164562Sgshapiro open connections to the same remote host at the same time. 561238032Speter This reduces load on the other machine, but can cause mail to 561338032Speter be delayed (for example, if one sendmail is delivering a huge 561438032Speter message, other sendmails won't be able to send even small 561538032Speter messages). Also, it requires another file descriptor (for the 561638032Speter lock file) per connection, so you may have to reduce 561738032Speter ConnectionCacheSize to avoid running out of per-process 561838032Speter file descriptors. Based on the persistent host status code 561938032Speter contributed by Paul Vixie and Mark Lovell. 562038032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 562138032Speter SafeFileEnvironment option is set. Problem noted by Bryan 562238032Speter Costales. 562338032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 562438032Speter file. Problem noted by Bryan Costales. 562538032Speter If a job was aborted using the interrupt signal (e.g., control-C from 562638032Speter the keyboard), on some occasions an empty df file would be 562738032Speter left around; these would collect in the queue directory. 562838032Speter Problem noted by Bryan Costales. 562938032Speter Change the makesendmail script to enhance the search for Makefiles 563038032Speter based on release number. For example, on SunOS 5.5.1, it will 563138032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 563238032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 563338032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 563438032Speter Webmasters. 563538032Speter When creating maps using "newaliases", always map the keys to lower 563638032Speter case when creating the map unless the -f flag is specified on 563738032Speter the map itself. Previously this was done based on the F=u 563838032Speter flag in the local mailer, which meant you could create aliases 563938032Speter that you could never access. Problem noted by Bob Wu of DEC. 564038032Speter When a job was read from the queue, the bits causing notification on 564138032Speter failure or delay were always set. This caused those 564238032Speter notifications to be sent even if NOTIFY=NEVER had been 564338032Speter specified. Problem noted by Steve Hubert of the University 564438032Speter of Washington, Seattle. 564538032Speter Add new configurable routine validate_connection (in conf.c). This 564638032Speter lets you decide if you are willing to accept traffic from 564738032Speter this host. If it returns FALSE, all SMTP commands will return 564838032Speter "550 Access denied". -DTCPWRAPPERS will include support for 564938032Speter TCP wrappers; you will need to add -lwrap to the link line. 565038032Speter (See src/READ_ME for details.) 565138032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 565238032Speter bounces. Some people seemed to think that this could be 565338032Speter confusing (even though it is true). Suggested by Motonori 565438032Speter Nakamura. 565538032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 565638032Speter user early in processing to avoid potential security problems. 565738032Speter However, this means that all .forward and :include: files must 565838032Speter be readable by that user, and all files to be written must be 565938032Speter writable by that user and all programs will be executed by that 566038032Speter user. It is also incompatible with the SafeFileEnvironment 566138032Speter option. In other words, it may not actually add much to 566238032Speter security. However, it should be useful on firewalls and other 566338032Speter places where users don't have accounts and the aliases file is 566438032Speter well constrained. 566538032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 566638032Speter only on the first attempt to delivery to an address. It could 566738032Speter be set to be lower than Timeout.connect on the principle that 566838032Speter the mail should go through quickly to responsive hosts; less 566938032Speter responsive hosts get to wait for the next queue run. 567038032Speter Fix a problem on Solaris that occasionally causes programs 567138032Speter (such as vacation) to hang with their standard input connected 567238032Speter to a UDP port. It also created some signal handling problems. 567338032Speter The problems turned out to be an interaction between vfork(2) 567438032Speter and some of the libraries, particularly NIS/NIS+. I am 567538032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 567638032Speter Change user class map to do the same matching that actual delivery 567738032Speter will do instead of just a /etc/passwd lookup. This adds 567838032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 567938032Speter The Timeout.* options are not safe -- they can be used to create a 568038032Speter denial-of-service attack. Problem noted by Christophe 568138032Speter Wolfhugel. 568243730Speter Don't send PostmasterCopy messages in the event of a "delayed" 568338032Speter notification. Suggested by Barry Bouwsma. 568438032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 568538032Speter option is set, since this disables VERB mode. Suggested 568638032Speter by John Hawkinson of MIT. 568738032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 568838032Speter by Motonori Nakamura of Kyoto University. 568938032Speter Only queue messages on transient .forward open failures if there 569043730Speter were no successful opens. The previous behavior caused it 569138032Speter to queue even if a "fall back" .forward was found. Problem 569238032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 569338032Speter and Computer Science (DISCS), NUS, Singapore. 569438032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 569538032Speter is bouncing because of a MIME error during 8->7 bit conversion; 569638032Speter the encapsulated message will bounce again, causing a loop. 569738032Speter Problem noted by Steve Hubert of the University of Washington. 569838032Speter Create xf (transcript) files using the TempFileMode option value 569938032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 570038032Speter National University of Singapore. 570138032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 570238032Speter detect cases where DefaultUid is set to something that the 570338032Speter system can't cope with. 570438032Speter PORTABILITY FIXES: 570538032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 570638032Speter Atlas International. 570738032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 570838032Speter <bicknell@ufp.org>. 570938032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 571038032Speter work on the first recipient of a message due to a 571138032Speter bug in the getpwent family.

Based on a patch from Randall 575438032Speter Winchester of the University of Maryland. 575538032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 575638032Speter Robert La Ferla of Hot Software. 575738032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 575838032Speter (where "code" is an exit status) on domains (previously 575938032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 576038032Speter Foundation. 576138032Speter CONFIG: hooks for IPv6-style domain literals. 576238032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 576338032Speter if it is undefined the AliasFile option is never set; this 576438032Speter should be transparent for most everyone. Suggested by John 576538032Speter Myers of CMU. 576638032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 576738032Speter domain listed in $=w is masqueraded. With it, only those 576838032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 576938032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 577038032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 577138032Speter hosts under those domains as well as the domain headers 577238032Speter themselves. For example, if a configuration had 577338032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 577438032Speter foo.com would be masqueraded; with it, *.foo.com would be 577538032Speter masqueraded as well. Based on an implementation by Richard 577638032Speter (Pug) Bainter of U. Texas. 577738032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 577838032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 577938032Speter Keys are user names; values are outgoing mail addresses. Yes, 578038032Speter this does overlap with the user database, and figuring out 578138032Speter just when to use which one may be tricky. Based on code 578238032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 578338032Speter from Per Hedeland of Ericsson. 578438032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 578538032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 578638032Speter Keys are either fully qualified addresses or just the host 578738032Speter part (with the @ sign). For example, a table containing: 578838032Speter info@foo.com foo-info 578938032Speter info@bar.com bar-info 579038032Speter @baz.org jane@elsewhere.net 579138032Speter would send all mail destined for info@foo.com to foo-info 579238032Speter (which is presumably an alias), mail addressed to info@bar.com 579338032Speter to bar-info, and anything addressed to anyone at baz.org will 579438032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 579538032Speter and baz.org must all be in $=w. Based on discussions with 579638032Speter a great many people. 579738032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 579838032Speter Suggested by Richard Bainter. 579938032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 580038032Speter "fax" mailer. 580138032Speter CONFIG: allow mailertable entries to resolve to local:user; this 580238032Speter passes the original user@host in to procmail-style local 580338032Speter mailers as the "detail" information to allow them to do 580438032Speter additional clever processing. From Joe Pruett of 580538032Speter Teleport Corporation. Delivery to the original user can 580638032Speter be done by specifying "local:" (with nothing after the colon). 580738032Speter CONFIG: allow any context that takes "mailer:domain" to also take 580838032Speter "mailer:user@domain" to force mailing to the given user; 580938032Speter "local:user" can also be used to do local delivery. This 581038032Speter applies on *_RELAY and in the mailertable entries. Based 581138032Speter on a suggestion by Ribert Kiessling of Easynet. 581238032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 581338032Speter limits the possible domains; this reduces the number of DNS 581438032Speter lookups required to support this feature. For example, 581538032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 581638032Speter to domains under my.site.com. Code contributed by Anthony 581738032Speter Thyssen <anthony@cit.gu.edu.au>. 581838032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 581938032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 582038032Speter of WPI. 582138032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 582238032Speter event you have to define local mailers. Suggested by 582338032Speter Gregory Shapiro of WPI. 582438032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 582538032Speter be misinterpreted as a list:...; syntax. Based on a patch by 582638032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 582738032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 582838032Speter remotely connected. The address host!user was being 582938032Speter converted to host!user@thishost instead of host!user@uurelay. 583038032Speter Problem noted by William Gianopoulos of Raytheon Company. 583138032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 583238032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 583338032Speter "User has moved"; the former wording was confusing if the 583438032Speter new address is still on the local host. Based on a suggestion 583538032Speter by Andreas Luik. 583638032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 583738032Speter However, the class is not pre-initialized to contain root. 583838032Speter Suggested by Gregory Neil Shapiro. 583938032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 584038032Speter Wolfhugel. 584138032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 584238032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 584338032Speter well: this produces a slightly different mailbox format (no 584438032Speter Content-Length: headers), file ownerships and modes are 584538032Speter different (not owned by group mail; mode 600 instead of 660), 584638032Speter and the local mailer flags will have to be tweaked (make them 584738032Speter match bsd4.4) in order to use this mailer. Patches from Paul 584838032Speter Hammann of the Missouri Research and Education Network. 584938032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 585038032Speter was a delivery error, such as if the ownership on the file 585138032Speter was wrong or the mode changed between the initial stat and 585238032Speter the open.

They were not 593838032Speter properly repaired in 8.7.1. 593938032Speter Completely delete the Bcc: header if and only if there are other 594038032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 594138032Speter last being a historic botch, of course). If Bcc: is the 594238032Speter only recipient header in the message, its value is tossed, 594343730Speter but the header name is kept. The old behavior (always keep 594438032Speter the header name and toss the value) allowed primary recipients 594538032Speter to see that a Bcc: went to _someone_. 594638032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 594738032Speter sender to <address> using -f'' syslog messages. Suggested 594838032Speter by Kari Hurtta. 594938032Speter If a sequence or switch map lookup entry gets a tempfail but then 595038032Speter continues on to another map type, but the name is not found, 595138032Speter return a temporary failure from the sequence or switch map. 595238032Speter For example, if hosts search ``dns files'' and DNS fails 595338032Speter with a tempfail, the hosts map will go on and search files, 595438032Speter but if it fails the whole thing should be a tempfail, not 595538032Speter a permanent (host unknown) failure, even though that is the 595638032Speter failure in the hosts.files map. This error caused hard 595738032Speter bounces when it should have requeued. 595838032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 595990792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 596038032Speter working properly due to excessive paranoia. Pointed out by 596138032Speter John Hawkinson of Panix. 596238032Speter An SMTP RCPT command referencing a host that gave a nameserver 596338032Speter timeout would return a 451 command (8.6 accepted it and 596443730Speter queued it locally). Revert to the 8.6 behavior in order 596538032Speter to simplify queue management for clustered systems. Suggested 596638032Speter by Gregory Neil Shapiro of WPI. The same problem could break 596738032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 596838032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 596938032Speter Infobiogen. 597038032Speter Fix possible buffer overflow in munchstring(). This was not a security 597138032Speter problem because you couldn't specify any argument to this 597238032Speter without first giving up root privileges, but it is still a 597338032Speter good idea to avoid future problems.

Pointed out by Mark Andrews of SGI and Jack Woolley 598738032Speter of Systems and Computer Technology Corporation. 598838032Speter If a message is sent to an address that fails, the error message that 598938032Speter is returned could show some extraneous "success" information 599038032Speter included even if the user did not request success notification, 599138032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 599238032Speter Config files that had no AliasFile definition were defaulting to 599338032Speter using /etc/aliases; this caused problems with nullclient 599438032Speter configurations.

Fix from Brian Coan of the 602638032Speter Association for Progressive Communications. 602738032Speter If MinQueueAge was set and a message was considered but not run 602838032Speter during a queue run and the Timeout.queuereturn interval was 602938032Speter reached, a "timed out" error message would be returned that 603038032Speter didn't include the failed address (and claimed to be a warning 603138032Speter even though it was fatal). The fix is to not return such 603238032Speter messages until they are actually tried, i.e., in the next 603338032Speter MinQueueAge interval.

From Tom Moore of AT&T GIS. 609038032Speter Shorten parameters passed to syslog() in some contexts to avoid a 609138032Speter bug in many vendors' implementations of that routine. Although 609238032Speter this isn't really a bug in sendmail per se, and my solution 609338032Speter has to assume that syslog() has at least a 1K buffer size 609438032Speter internally (I know some vendors have shortened this 609538032Speter dramatically -- they're on their own), sendmail is a popular 609638032Speter target. Also, limit the size of %s arguments in sprintf. 609738032Speter These both have possible security implications. Solutions 609838032Speter suggested by Casper Dik of Sun's Network Security Group 609938032Speter (Holland), Mark Seiden, and others. 610038032Speter Fix a problem that might cause a non-standard -B (body type) 610138032Speter parameter to be passed to the next server with undefined 610238032Speter results.

Robert 611038032Speter Elz. 611138032Speter Avoid some possible null pointer dereferences. Fixes from Randy 611238032Speter Martin <WOLF@CLEMSON.EDU> 611338032Speter When sendmail starts up on systems that have no fully qualified 611438032Speter domain name (FQDN) anywhere in the first matching host map 611538032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 611638032Speter sendmail would sleep to try to find a FQDN, which it really 611738032Speter really needs. This has been changed to fall through to the 611838032Speter next map type if it can't find a FQDN -- i.e., if the hosts 611938032Speter file doesn't have a FQDN, it will try dns even though the 612038032Speter short name was found in /etc/hosts. This is probably a crock, 612138032Speter but many people have hosts files without FQDNs. Remember: 612238032Speter domain names are your friends. 612338032Speter Log a high-priority message if you can't find your FQDN during startup. 612438032Speter Suggested by Simon Barnes of Schlumberger Limited. 612538032Speter When using Hesiod, initialize it early to improve error reporting. 612638032Speter Patch from Don Lewis of Silicon Systems, Inc. 612738032Speter Apparently at least some versions of Linux have a 90 !minute!

This can 625038032Speter result in an extra 60 second delay on startup if your system 625138032Speter hostname (as returned by hostname(1)) has no dot and no names 625238032Speter listed in /etc/hosts or your NIS map have a dot. 625338032Speter Check for proper domain name on HELO and EHLO commands per 625438032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 625538032Speter of Michigan Technological University. 625638032Speter Relax chownsafe rules slightly -- old version said that if you 625738032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 625838032Speter if fpathconf returned EINVAL or ENOSYS), assume that 625938032Speter chown is not safe. The new version falls back to whether 626038032Speter you are on a BSD system or not. This is important for 626138032Speter SunOS, which apparently always returns one of those 626238032Speter error codes. This impacts whether you can mail to files 626338032Speter or not. 626438032Speter Syntax errors such as unbalanced parentheses in the configuration 626538032Speter file could be omitted if you had "Oem" prior to the 626638032Speter syntax error in the config file. Change to always print 626738032Speter the error message. It was especially weird because it 626838032Speter would cause a "warning" message to be sent to the Postmaster 626938032Speter for every message sent (but with no transcript). Problem 627038032Speter noted by Gregory Paris of Motorola. 627138032Speter Rewrite collect and putbody to handle full 8-bit data, including 627238032Speter zero bytes. These changes are internally extensive, but 627338032Speter should have minimal impact on external function. 627438032Speter Allow full words for option names -- if the option letter is 627538032Speter (apparently) a space, then take the word following -- e.g., 627638032Speter O MatchGECOS=TRUE 627738032Speter The full list of old and new names is as follows: 627838032Speter 7 SevenBitInput 627938032Speter 8 EightBitMode 628038032Speter A AliasFile 628138032Speter a AliasWait 628238032Speter B BlankSub 628338032Speter b MinFreeBlocks/MaxMessageSize 628438032Speter C CheckpointInterval 628538032Speter c HoldExpensive 628638032Speter D AutoRebuildAliases 628738032Speter d DeliveryMode 628838032Speter E ErrorHeader 628938032Speter e ErrorMode 629038032Speter f SaveFromLine 629138032Speter F TempFileMode 629238032Speter G MatchGECOS 629338032Speter H HelpFile 629438032Speter h MaxHopCount 629538032Speter i IgnoreDots 629638032Speter I ResolverOptions 629738032Speter J ForwardPath 629838032Speter j SendMimeErrors 629938032Speter k ConnectionCacheSize 630038032Speter K ConnectionCacheTimeout 630138032Speter L LogLevel 630238032Speter l UseErrorsTo 630338032Speter m MeToo 630438032Speter n CheckAliases 630538032Speter O DaemonPortOptions 630638032Speter o OldStyleHeaders 630738032Speter P PostmasterCopy 630838032Speter p PrivacyOptions 630938032Speter Q QueueDirectory 631038032Speter q QueueFactor 631138032Speter R DontPruneRoutes 631238032Speter r, T Timeout 631338032Speter S StatusFile 631438032Speter s SuperSafe 631538032Speter t TimeZoneSpec 631638032Speter u DefaultUser 631738032Speter U UserDatabaseSpec 631843730Speter V FallbackMXHost 631938032Speter v Verbose 632038032Speter w TryNullMXList 632138032Speter x QueueLA 632238032Speter X RefuseLA 632338032Speter Y ForkEachJob 632438032Speter y RecipientFactor 632538032Speter z ClassFactor 632638032Speter Z RetryFactor 632738032Speter The old macros that passed information into sendmail have 632838032Speter been changed to options; those correspondences are: 632938032Speter $e SmtpGreetingMessage 633038032Speter $l UnixFromLine 633138032Speter $o OperatorChars 633238032Speter $q (deleted -- not necessary) 633338032Speter To avoid possible problems with an older sendmail, 633438032Speter configuration level 6 is accepted by this version of 633538032Speter sendmail; any config file using the new names should 633638032Speter specify "V6" in the configuration. 633738032Speter Change address parsing to properly note that a phrase before a 633838032Speter colon and a trailing semicolon are essentially the same 633938032Speter as text outside of angle brackets (i.e., sendmail should 634038032Speter treat them as comments). This is to handle the 634138032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 634238032Speter assume that ``group name:'' is a comment on the first 634338032Speter address and the ``;'' is a comment on the last address). 634438032Speter This requires config file support to get right. It does 634538032Speter understand that :: is NOT this syntax, and can be turned 634638032Speter off completely by setting the ColonOkInAddresses option. 634738032Speter Level 6 config files added with new mailer flags: 634838032Speter A Addresses are aliasable. 634938032Speter i Do udb rewriting on envelope as well as header 635038032Speter sender lines. Applies to the from address mailer 635138032Speter flags rather than the recipient mailer flags. 635238032Speter j Do udb rewriting on header recipient addresses. 635338032Speter Applies to the sender mailer flags rather than the 635438032Speter recipient mailer flags. 635538032Speter k Disable check for loops when doing HELO command. 635638032Speter o Always run as the mail recipient, even on local 635738032Speter delivery. 635838032Speter w Check for an /etc/passwd entry for this user. 635938032Speter 5 Pass addresses through ruleset 5. 636038032Speter : Check for :include: on this address. 636138032Speter | Check for |program on this address. 636238032Speter / Check for /file on this address. 636338032Speter @ Look up sender header addresses in the user 636438032Speter database. Applies to the mailer flags for the 636538032Speter mailer corresponding to the envelope sender 636638032Speter address, rather than to recipient mailer flags. 636738032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 636838032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 636938032Speter mailers, and the ColonOkInAddresses option. 637038032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 637138032Speter John Beck of Hewlett-Packard, who generously contributed 637238032Speter their implementation to me, which I then didn't use (see 637338032Speter mime.c for an explanation of why). This adds the 637438032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 637538032Speter to control handling of 8-bit data. These have to cope with 637638032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 637738032Speter 8-bit data that is entered without declaring it as 8-bit 637838032Speter MIME -- technically this is illegal according to the 637938032Speter specs) and labelled 8-bit data (that is, it was declared 638038032Speter as 8BITMIME in the ESMTP session or by using the 638138032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 638238032Speter set then 8-bit data is sent to non-8BITMIME machines 638338032Speter instead of converting to 7 bit (essentially using 638438032Speter just-send-8 semantics). The values for EightBitMode are: 638538032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 638638032Speter any necessary conversion of 8BITMIME to 7BIT 638738032Speter (essentially, the full MIME option). 638838032Speter p pass unlabelled 8-bit input, but convert labelled 638938032Speter 8BITMIME input to 7BIT as required (default). 639038032Speter s strict adherence: reject unlabelled 8-bit input, 639138032Speter convert 8BITMIME to 7BIT as required. The F=8 639238032Speter flag is ignored. 639338032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 639438032Speter the setting of F=8. 639538032Speter Add new internal class 'n', which is the set of MIME Content-Types 639638032Speter which can not be 8 to 7 bit encoded because of other 639738032Speter considerations. Types "multipart/*" and "message/*" are 639838032Speter never directly encoded (although their components can be). 639938032Speter Add new internal class 's', which is the set of subtypes of the 640038032Speter MIME message/* content type that can be treated as though 640138032Speter they are an RFC822 message. It is predefined to have 640238032Speter "rfc822". Suggested By Kari Hurtta. 640338032Speter Add new internal class 'e'. This is the set of MIME 640438032Speter Content-Transfer-Encodings that can be converted to 640538032Speter a seven bit format (Quoted-Printable or Base64). It is 640638032Speter preinitialized to contain "7bit", "8bit", and "binary". 640738032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 640838032Speter short name) to set the default character set to use in the 640938032Speter Content-Type: header when doing encoding of an 8-bit message 641038032Speter which isn't marked as MIME into MIME format. If the C= 641138032Speter parameter is set on the Envelope From address, use that as 641238032Speter the default encoding; else use the DefaultCharSet option. 641338032Speter If neither is set, it defaults to "unknown-8bit" as 641438032Speter suggested by RFC 1428 section 3. 641538032Speter Allow ``U=user:group'' field in mailer definition to set a default 641638032Speter user and group that a mailer will be executed as. This 641738032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 641838032Speter also set, it is the uid/gid that will always be used (that 641938032Speter is, the controlling address is ignored). The values may be 642038032Speter numeric or symbolic; if only a symbolic user is given (no 642138032Speter group) that user's default group in the passwd file is used 642238032Speter as the group. Based on code donated by Chip Rosenthal of 642338032Speter Unicom. 642438032Speter Allow `u' option to also accept user:group as a value, in the same 642538032Speter fashion as the U= mailer option. 642638032Speter Add the symbolic time zone name in the Arpanet format dates (as 642738032Speter a comment). This adds a new compile-time configuration 642838032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 642938032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 643038032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 643138032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 643238032Speter timezone()), or TZ_NONE (don't include the comment). Code 643338032Speter from Chip Rosenthal. 643438032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 643538032Speter For example, 643638032Speter O Timeout.helo = 2m 643738032Speter There are also two new suboptions "queuereturn" and 643838032Speter "queuewarn"; these subsume the old T option. Thus, to 643938032Speter set them both the preferred new syntax is 644038032Speter O Timeout.queuereturn = 5d 644138032Speter O Timeout.queuewarn = 4h 644238032Speter Sort queue by host name instead of by message priority if the 644338032Speter QueueSortOrder option (no short name) is set is set to 644438032Speter ``host''. This makes better use of the connection cache, 644538032Speter but may delay more ``interactive'' messages behind large 644638032Speter backlogs under some circumstances. This is probably a 644738032Speter good option if you have high speed links or don't do lots 644838032Speter of ``batch'' messages, but less good if you are using 644938032Speter something like PPP on a 14.4 modem. Based on code 645038032Speter contributed by Roy Mongiovi of Georgia Tech (my main 645138032Speter contribution was to make it configurable). 645238032Speter Save i-number of df file in qf file to simplify rebuilding of queue 645338032Speter after disastrous disk crash. Suggested by Kyle Jones of 645438032Speter UUNET; closely based on code from KJS DECWRL code written 645538032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 645638032Speter are NOT back compatible with 8.6 -- that is, you can convert 645738032Speter from 8.6 to 8.7, but not the other direction. 645838032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 645938032Speter route-addrs in envelopes; this is because in some cases 646038032Speter they can be sent to the shell, which interprets them as 646138032Speter I/O redirection. 646238032Speter Don't include error file (option E) with return-receipts; this 646338032Speter can be confusing. 646438032Speter Don't send "Warning: cannot send" messages to owner-* or 646538032Speter *-request addresses. Suggested by Christophe Wolfhugel 646638032Speter of the Institut Pasteur, Paris. 646738032Speter Allow -O command line flag to set long form options. 646838032Speter Add "MinQueueAge" option to set the minimum time between attempts 646938032Speter to run the queue. For example, if the queue interval 647038032Speter (-q value) is five minutes, but the minimum queue age 647138032Speter is fifteen minutes, jobs won't be tried more often than 647238032Speter once every fifteen minutes. This can be used to give 647338032Speter you more responsiveness if your delivery mode is set to 647438032Speter queue-only. 647538032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 647638032Speter :include: and .forward files. 647738032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 647838032Speter key field name, the value field name, and the field 647938032Speter delimiter. The field delimiter can be a single character 648038032Speter or the sequence "\t" or "\n" for tab or newline. 648138032Speter These are for use by NIS+ and similar access methods. 648238032Speter Change maps to always strip quotes before lookups; the -q flag 648343730Speter turns off this behavior. Suggested by Motonori Nakamura. 648438032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 648538032Speter key and value field names respectively. Code donated by 648638032Speter Sun Microsystems. 648738032Speter Add "hesiod" map class. The "file name" is used as the 648838032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 648938032Speter first value found for the match. Code donated by Scott 649038032Speter Hutton of Indiana University. 649138032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 649238032Speter specify the name of the property that is searched as the 649338032Speter key and a -v flag to specify the name of the property that 649438032Speter is returned as the value (defaults to "members"). The 649538032Speter default map is "/aliases". Some code based on code 649638032Speter contributed by Robert La Ferla of Hot Software. 649738032Speter Add "text" map class. This does slow, linear searches through 649838032Speter text files. The -z flag specifies a column delimiter 649938032Speter (defaults to any sequence of white space), the -k flag 650038032Speter sets the key column number, and the -v flag sets the 650138032Speter value column number. Lines beginning with `#' are treated 650238032Speter as comments. 650338032Speter Add "program" map class to execute arbitrary programs. The search 650438032Speter key is presented as the last argument; the output is one 650538032Speter line read from the programs standard output. Exit statuses 650638032Speter are from sysexits.h. 650738032Speter Add "sequence" map class -- searches maps in sequence until it 650838032Speter finds a match. For example, the declarations: 650938032Speter Kmap1 ... 651038032Speter Kmap2 ... 651138032Speter Kmapseq sequence map1 map2 651238032Speter defines a map "mapseq" that first searches map1; if the 651338032Speter value is found it is returned immediately, otherwise 651438032Speter map2 is searched and the value returned. 651538032Speter Add "switch" map class. This is much like "sequence" except that 651638032Speter the ordering is fetched from an external file, usually 651738032Speter the system service switch. The parameter is the name of 651838032Speter the service to switch on, and the maps that it will use 651938032Speter are the name of the switch map followed by ".service_type". 652038032Speter For example, if the declaration of the map is 652138032Speter Ksample switch hosts 652238032Speter and the system service switch specifies that hosts are 652338032Speter looked up using dns and nis in that order, then this is 652438032Speter equivalent to 652538032Speter Ksample sequence sample.dns sample.nis 652638032Speter The subordinate maps (sample.*) must already be defined. 652738032Speter Add "user" map class -- looks up users using getpwnam. Takes a 652838032Speter "-v field" flag on the definition that tells what passwd 652938032Speter entry to return -- legal values are name, passwd, uid, gid, 653038032Speter gecos, dir, and shell. Generally expected to be used with 653138032Speter the -m (matchonly) flag. 653238032Speter Add "bestmx" map class -- returns the best MX value for the host 653338032Speter listed as the value. If there are several "best" MX records 653438032Speter for this host, one will be chosen at random. 653538032Speter Add "userdb" map class -- looks up entries in the user database. 653638032Speter The "file name" is actually the tag that will be used, 653738032Speter typically "mailname". If there are multiple entries 653838032Speter matching the name, the one chosen is undefined. 653938032Speter Add multiple queue timeouts (both return and warning). These are 654038032Speter set by the Precedence: or Priority: header fields to one of 654138032Speter three values. If a Priority: is set and has value "normal", 654264562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 654338032Speter used. If no priority is set, the Precedence: is consulted; 654438032Speter if negative, non-urgent timeouts are used; if greater than 654538032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 654638032Speter are used. The timeouts are set by setting the six timeouts 654738032Speter queue{warn,return}.{urgent,normal,non-urgent}. 654838032Speter Fix problem when a mail address is resolved to a $#error mailer 654938032Speter with a temporary failure indication; it works in SMTP, 655038032Speter but when delivering locally the mail is silently discarded. 655138032Speter This patch, from Kyle Jones of UUNET, bounces it instead 655238032Speter of queueing it (queueing is very hard). 655338032Speter When using /etc/hosts or NIS-style lookups, don't assume that 655438032Speter the first name in the list is the best one -- instead, 655538032Speter search for the first one with a dot. For example, if 655638032Speter an /etc/hosts entry reads 655738032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 655838032Speter this change will use the second name as the canonical 655938032Speter machine name instead of the initial, unqualified name. 656038032Speter Change dequote map to replace spaces in quoted text with a value 656138032Speter indicated by the -s flag on the dequote map definition. 656238032Speter For example, ``Mdequote dequote -s_'' will change 656338032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 656438032Speter quoted (because of the space character). Suggested by Dan 656538032Speter Oscarsson for use in X.400 addresses. 656638032Speter Implement long macro names as ${name}; long class names can 656738032Speter be similarly referenced as $={name} and $~{name}. 656838032Speter Definitions are (e.g.) ``D{name}value''. Names that have 656938032Speter a leading lower case letter or punctuation characters are 657038032Speter reserved for internal use by sendmail; i.e., config files 657138032Speter should use names that begin with a capital letter. Based 657238032Speter on code contributed by Dan Oscarsson. 657338032Speter Fix core dump if getgrgid returns a null group list (as opposed 657438032Speter to an empty group list, that is, a pointer to a list 657538032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 657638032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 657738032Speter failed, it called syserr which called newstr which called 657838032Speter xalloc.... The newstr is now avoided for "panic" messages. 657938032Speter Reported by Stuart Kemp of James Cook University. 658038032Speter Improve connection cache timeouts; previously, they were not even 658138032Speter checked if you were delivering to anything other than an 658238032Speter IPC-connected host, so a series of (say) local mail 658338032Speter deliveries could cause cached connections to be open 658438032Speter much longer than the specified timeout. 658538032Speter If an incoming message exceeds the maximum message size, stop 658638032Speter writing the incoming bytes to the queue data file, since 658738032Speter this can fill your mqueue partition -- this is a possible 658838032Speter denial-of-service attack. 658938032Speter Don't reject all numeric local user names unless HESIOD is 659038032Speter defined. It turns out that Posix allows all-numeric 659138032Speter user names. Fix from Tony Sanders of BSDI. 659238032Speter Add service switch support. If the local OS has a service 659338032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 659438032Speter on DEC systems) that will be used; otherwise, it falls back 659538032Speter to using a local mechanism based on the ServiceSwitchFile 659638032Speter option (default: /etc/service.switch). For example, if the 659738032Speter service switch lists "files" and "nis" for the aliases 659838032Speter service, that will be the default lookup order. the "files" 659938032Speter ("local" on DEC) service type expands to any alias files 660038032Speter you listed in the configuration file, even if they aren't 660138032Speter actually file lookups. 660238032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 660338032Speter variable which tells whether or not DNS should be considered 660438032Speter canonical. This is now determined based on whether or not 660538032Speter "dns" is in the service list for "hosts". 660638032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 660738032Speter Status Notifications). DSN notifications override 660838032Speter Return-Receipt-To: headers, which are bogus anyhow -- 660938032Speter support for them has been removed. 661038032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 661138032Speter definitions to define the types used in DSN returns for 661238032Speter MTA names, addresses, and diagnostics respectively. 661338032Speter Extend heuristic to force running in ESMTP mode to look for the 661438032Speter five-character string "ESMTP" anywhere in the 220 greeting 661538032Speter message (not just the second line). This is to provide 661638032Speter better compatibility with other ESMTP servers. 661738032Speter Print sequence number of job when running the queue so you can 661838032Speter easily see how much progress you have made. Suggested 661938032Speter by Peter Wemm of DIALix. 662038032Speter Map newlines to spaces in logged message-ids; some versions of 662138032Speter syslog truncate the rest of the line after newlines. 662238032Speter Suggested by Fletcher Mattox of U. Texas. 662338032Speter Move up forking for job runs so that if a message is split into 662438032Speter multiple envelopes you don't get "fork storms" -- this 662538032Speter also improves the connection cache utilization. 662638032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 662738032Speter the purposes of refusing to send error returns. Suggested 662838032Speter by Motonori Nakamura of Ritsumeikan University. 662938032Speter Relax rules on when a file can be written when referenced from 663038032Speter the aliases file: use the default uid/gid instead of the 663138032Speter real uid/gid. This allows you to create a file owned by 663238032Speter and writable only by the default uid/gid that will work 663390792Sgshapiro all the time (without having the set-user-ID bit set). Change 663438032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 663538032Speter Microsystems. 663638032Speter Add "DialDelay" option (no short name) to provide an "extra" 663738032Speter delay for dial on demand systems. If this is non-zero 663838032Speter and a connect fails, sendmail will wait this long and 663938032Speter then try again. If it takes longer than the kernel 664038032Speter timeout interval to establish the connection, this 664138032Speter option can give the network software time to establish 664238032Speter the link. The default units are seconds. 664338032Speter Move logging of sender information to be as early as possible; 664438032Speter previously, it could be delayed a while for SMTP mail 664538032Speter sent to aliases. Suggested by Brad Knowles of the 664638032Speter Defense Information Systems Agency. 664738032Speter Call res_init() before setting RES_DEBUG; this is required by 664838032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 664938032Speter the National Computer Security Center. 665038032Speter Add xdelay= field in logs -- this is a transaction delay, telling 665138032Speter you how long it took to deliver to this address on the 665238032Speter last try. It is intended to be used for sorting mailing 665338032Speter lists to favor "quick" addresses. Provided for use by 665438032Speter the mailprio scripts (see below). 665538032Speter If a map cannot be opened, and that map is non-optional, and 665638032Speter an address requires that map for resolution, queue the 665738032Speter map instead of bouncing it. This involves creating a 665838032Speter pseudo-class of maps called "bogus-map" -- if a required 665938032Speter map cannot be opened, the class is changed to bogus-map; 666038032Speter all queries against bogus-map return "tempfail". The 666138032Speter bogus-map class is not directly accessible. A sample 666238032Speter implementation was donated by Jem Taylor of Glasgow 666338032Speter University Computing Service. 666438032Speter Fix a possible core dump when mailing to a program that talks 666538032Speter SMTP on its standard input. Fix from Keith Moore of 666638032Speter the University of Kentucky. 666738032Speter Make it possible to resolve filenames to $#local $: @ /filename; 666838032Speter previously, the "@" would cause it to not be recognized 666938032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 667038032Speter Accept a -1 signal to re-exec the daemon. This only works if 667138032Speter argv[0] is a full path to sendmail. 667238032Speter Fix bug in "addr=..." field in O option on little-endian machines 667338032Speter -- the network number wasn't being converted to network 667438032Speter byte order. Patch from Kurt Lidl of Pix Technologies 667538032Speter Corporation. 667638032Speter Pre-initialize the resolver early on; this is to avoid a bug with 667738032Speter BIND 4.9.3 that can cause the _res.retry field to get 667838032Speter reset to zero, causing all name server lookups to time 667938032Speter out. Fix from Matt Day of Artisoft. 668038032Speter Restore T line (trusted users) in config file -- but instead of 668138032Speter locking out the -f flag, they just tell whether or not 668238032Speter an X-Authentication-Warning: will be added. This really 668338032Speter just creates new entries in class 't', so "Ft/file/name" 668438032Speter can be used to read trusted user names from a file. 668538032Speter Trusted users are also allowed to execute programs even 668638032Speter if they have a shell that isn't in /etc/shells. 668738032Speter Improve NEWDB alias file rebuilding so it will create them 668838032Speter properly if they do not already exist. This had been 668938032Speter a MAYBENEXTRELEASE feature in 8.6.9. 669038032Speter Check for @:@ entry in NIS maps before starting up to avoid 669138032Speter (but not prevent, sigh) race conditions. This ought to 669238032Speter be handled properly in ypserv, but isn't. Suggested by 669338032Speter Michael Beirne of Motorola. 669438032Speter Refuse connections if there isn't enough space on the filesystem 669538032Speter holding the queue. Contributed by Robert Dana of Wolf 669638032Speter Communications. 669738032Speter Skip checking for directory permissions in the path to a file 669838032Speter when checking for file permissions iff setreuid() 669938032Speter succeeded -- it is unnecessary in that case. This avoids 670038032Speter significant performance problems when looking for .forward 670138032Speter files. Based on a suggestion by Win Bent of USC. 670238032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 670338032Speter arbitrary ruleset number assigned or "Sname = integer" 670438032Speter to assign a specific ruleset number. Reference is 670538032Speter $>name_or_number. Names can be composed of alphas, digits, 670638032Speter underscore, or hyphen (first character must be non-numeric). 670738032Speter Allow -o flag on AliasFile lines to make the alias file optional. 670838032Speter From Bryan Costales of ICSI. 670938032Speter Add NoRecipientAction option to handle the case where there is 671038032Speter no legal recipient header in the message. It can take 671138032Speter on values: 671238032Speter None Leave the message as is. The 671338032Speter message will be passed on even 671438032Speter though it is in technically 671538032Speter illegal syntax. 671638032Speter Add-To Add a To: header with any 671738032Speter recipients that it can find from 671838032Speter the envelope. This risks exposing 671938032Speter Bcc: recipients. 672038032Speter Add-Apparently-To Add an Apparently-To: header. This 672138032Speter has almost no redeeming social value, 672238032Speter and is provided only for back 672338032Speter compatibility. 672438032Speter Add-To-Undisclosed Add a header reading 672538032Speter To: undisclosed-recipients:; 672638032Speter which will have the effect of 672738032Speter making the message legal without 672838032Speter exposing Bcc: recipients. 672938032Speter Add-Bcc To add an empty Bcc: header. 673038032Speter There is a chance that mailers down 673138032Speter the line will delete this header, 673238032Speter which could cause exposure of Bcc: 673338032Speter recipients. 673438032Speter The default is NoRecipientAction=None. 673538032Speter Truncate (rather than delete) Bcc: lines in the header. This 673638032Speter should prevent later sendmails (at least, those that don't 673738032Speter themselves delete Bcc:) from considering this message to 673838032Speter be non-conforming -- although it does imply that non-blind 673938032Speter recipients can see that a Bcc: was sent, albeit not to whom. 674038032Speter Add SafeFileEnvironment option. If declared, files named as delivery 674138032Speter targets must be regular files in addition to the regular 674238032Speter checks. Also, if the option is non-null then it is used as 674338032Speter the name of a directory that is used as a chroot(2) 674438032Speter environment for the delivery; the file names listed in an 674538032Speter alias or forward should include the name of this root. 674638032Speter For example, if you run with 674738032Speter O SafeFileEnvironment=/arch 674838032Speter then aliases should reference "/arch/rest/of/path". If a 674938032Speter value is given, sendmail also won't try to save to 675038032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 675138032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 675238032Speter Support -A flag for alias files; this will comma concatenate like 675338032Speter entries. For example, given the aliases: 675438032Speter list: member1 675538032Speter list: member2 675638032Speter and an alias file declared as: 675738032Speter OAhash:-A /etc/aliases 675838032Speter the final alias inserted will be "list: member1,member2"; 675938032Speter without -A you will get an error on the second and subsequent 676038032Speter alias for "list". Contributed by Bryan Costales of ICSI. 676138032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 676238032Speter Fix a problem that could cause very long addresses to core dump in 676338032Speter some special circumstances. Problem pointed out by Allan 676438032Speter Johannesen. 676538032Speter (Internal change.) Change interface to expand() (macro expansion) 676638032Speter to be simpler and more consistent. 676738032Speter Delete check for funny qf file names. This didn't really give 676838032Speter any extra security and caused some people some problems. 676938032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 677038032Speter at compile time.) Suggested by Kyle Jones of UUNET. 677138032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 677238032Speter merge with DSN code; this is simpler and more consistent. 677338032Speter This may affect some people who have written their own 677438032Speter checkcompat() routine. 677538032Speter (Internal change.) Eliminate `D' line in qf file. The df file 677638032Speter is now assumed to be the same name as the qf file (with 677738032Speter the `q' changed to a `d', of course). 677838032Speter Avoid forking for delivery if all recipient mailers are marked as 677938032Speter "expensive" -- this can be a major cost on some systems. 678038032Speter Essentially, this forces sendmail into "queue only" mode 678138032Speter if all it is going to do is queue anyway. 678238032Speter Avoid sending a null message in some rather unusual circumstances 678338032Speter (specifically, the RCPT command returns a temporary 678438032Speter failure but the connection is lost before the DATA 678538032Speter command). Fix from Scott Hammond of Secure Computing 678638032Speter Corporation. 678738032Speter Change makesendmail to use a somewhat more rational naming scheme: 678838032Speter Makefiles and obj directories are named $os.$rel.$arch, 678938032Speter where $os is the operating system (e.g., SunOS), $rel is 679038032Speter the release number (e.g., 5.3), and $arch is the machine 679138032Speter architecture (e.g., sun4). Any of these can be omitted, 679238032Speter and anything after the first dot in a release number can 679338032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 679438032Speter version used $os.$arch.$rel and was rather less general. 679538032Speter Change makesendmail to do a "make depend" in the target directory 679638032Speter when it is being created. This involves adding an empty 679738032Speter "depend:" entry in most Makefiles. 679838032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 679938032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 680038032Speter of the Finnish Meteorological Institute. 680138032Speter Fix problem that could cause multiple responses to DATA command 680238032Speter on header syntax errors (e.g., lines beginning with colons). 680338032Speter Problem noted by Jens Thomassen of the University of Oslo. 680438032Speter Don't let null bytes in headers cause truncation of the rest of 680538032Speter the header. 680638032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 680738032Speter Increase timeouts on message data puts to allow time for receivers 680838032Speter to canonify addresses in headers on the fly. This is still 680938032Speter a rather ugly heuristic. From Motonori Nakamura. 681038032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 681138032Speter records are not used when canonifying names, and when MX 681238032Speter lookups are done for addressing they must be fully 681338032Speter qualified. This is useful if you have a wildcard MX record, 681438032Speter although it may cause other problems. In general, don't use 681538032Speter wildcard MX records. Patch from Motonori Nakamura. 681638032Speter Eliminate default two-line SMTP greeting message. Instead of 681738032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 681838032Speter is added between the first and second word of the first 681938032Speter line of the greeting message (i.e., immediately after the 682038032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 682138032Speter compile flag. Old sendmails won't see the ESMTP, but that's 682238032Speter acceptable because SIZE was the only useful extension that 682338032Speter old sendmails understand. 682438032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 682538032Speter invoked state dumps. From Masaharu Onishi. 682638032Speter Allow on-line comments in .forward and :include: files; they are 682738032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 682838032Speter is a space or a tab. This is intended for native 682938032Speter representation of non-ASCII sets such as Japanese, where 683038032Speter existing encodings would be unreadable or would lose 683138032Speter data -- for example, 683238032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 683338032Speter (romanized/less information) 683438032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 683538032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 683638032Speter (with MIME encoding, not human readable) 683738032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 683838032Speter (native encoding with ISO-2022-JP) 683938032Speter The last form is human readable in the Japanese environment. 684038032Speter Based on a fix from (surprise!) Motonori Nakamura. 684138032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 684238032Speter messages to that host; these are most frequently associated 684338032Speter with addresses rather than the host, with the exception of 684438032Speter 421 (service shutting down). The effect was to cause queues 684538032Speter to sometimes take an excessive time to flush. Reported by 684638032Speter Robert Sargent of Southern Geographics Technologies and 684738032Speter Eric Prestemon of American University. 684838032Speter Add Nice=N mailer option to set the niceness at which a mailer will 684938032Speter run. This is actually a relative niceness (that is, an 685038032Speter increment on the background value). 685138032Speter Log queue runs that are skipped due to high loads. They are logged 685238032Speter at LOG_INFO priority iff the log level is > 8. Contributed 685338032Speter by Bruce Nagel of Data General. 685438032Speter Allow the error mailer to accept a DSN-style error status code 685538032Speter instead of an sysexits status code in the host part. 685638032Speter Anything with a dot will be interpreted as a DSN-style code. 685738032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 685838032Speter to encode characters that might be munged by an EBCDIC system 685938032Speter in addition to the set required by RFC 1521. The additional 686038032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 686138032Speter (Think of "IBM 360" as the mnemonic for this flag.) 686238032Speter Change check for mailing to files to look for a pathname of [FILE] 686338032Speter rather than looking for the mailer named *file*. The mapping 686438032Speter of leading slashes still goes to the *file* mailer. This 686538032Speter allows you to implement the *file* mailer as a separate 686638032Speter program, for example, to insert a Content-Length: header 686738032Speter or do special security policy. However, note that the usual 686838032Speter initial checking for the file permissions is still done, and 686938032Speter the program in question needs to be very careful about how 687038032Speter it does the file write to avoid security problems. 687138032Speter Be able to read ~root/.forward even if the path isn't accessible to 687238032Speter regular users. This is disrecommended because sendmail 687338032Speter sometimes does not run as root (e.g., when an unsafe option 687438032Speter is specified on the command line), but should otherwise be 687538032Speter safe because .forward files must be owned by the user for 687638032Speter whom mail is being forwarded, and cannot be a symbolic link. 687738032Speter Suggested by Forrest Aldrich of Wang Laboratories. 687838032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 687938032Speter file. This is used for canonifying hostnames when the 688038032Speter service type is "files". 688138032Speter Implement programs on F (read class from file) line. The syntax is 688238032Speter Fc|/path/to/program to read the output from the program 688338032Speter into class "c". 688438032Speter Probe the network interfaces to find alternate names for this 688538032Speter host. Requires the SIOCGIFCONF ioctl call. Code 688638032Speter contributed by SunSoft. 688738032Speter Add "E" configuration line to set or propagate environment 688838032Speter variables into children. "E<envar>" will propagate 688938032Speter the named variable from the environment when sendmail 689038032Speter was invoked into any children it calls; "E<envar>=<value>" 689138032Speter sets the named variable to the indicated value. Any 689238032Speter variables not explicitly named will not be in the child 689338032Speter environment. However, sendmail still forces an 689438032Speter "AGENT=sendmail" environment variable, in part to enforce 689538032Speter at least one environment variable, since many programs and 689638032Speter libraries die horribly if this is not guaranteed. 689738032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 689838032Speter alias databases -- new algorithm looks for the substring 689938032Speter "/yp/" in the file name. This is more portable and involves 690038032Speter less overhead. Suggested by Motonori Nakamura. 690138032Speter Dynamically allocate the queue work list so that you don't lose 690238032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 690338032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 690438032Speter should not need to be changed) and the MaxQueueRunSize option, 690538032Speter which is the absolute maximum number of jobs that will ever 690638032Speter be handled in a single queue run. Based on code contributed 690738032Speter by Brian Coan of the Institute for Global Communications. 690838032Speter Log message when a message is dropped because it exceeds the maximum 690938032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 691038032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 691138032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 691238032Speter of Mark G. Thomas Consulting. 691338032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 691438032Speter OS-dependent defines). The old semantic of -d0.1 to not 691538032Speter run the daemon in background has been moved to -d99.100, 691638032Speter and the old 52.5 flag (to avoid disconnect() from closing 691738032Speter all output files) has been moved to 52.100. This makes 691838032Speter things more consistent (flags below .100 don't change 691938032Speter semantics) and separates out the backgrounding so that 692038032Speter it doesn't happen automatically on other unrelated debugging 692138032Speter flags. 692238032Speter If -t is used but no addresses are found in the header, give an 692338032Speter error message rather than just doing nothing. Fix from 692438032Speter Motonori Nakamura. 692538032Speter On systems (like SunOS) where the effective gid is not necessarily 692638032Speter included in the group list returned by getgroups(), the 692738032Speter `restrictmailq' option could sometimes cause an authorized 692838032Speter user to not be able to use `mailq'. Fix from Charles Hannum 692938032Speter of MIT. 693038032Speter Allow symbolic service names for [IPC] mailers. Suggested by 693138032Speter Gerry Magennis of Logica International. 693238032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 693338032Speter when running DNS. For example, if the name FTP.Foo.ORG is 693438032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 693538032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 693638032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 693738032Speter This is technically illegal under RFC 822 and 1123, but the 693838032Speter IETF is moving toward legalizing it. Note that turning on 693938032Speter this option is not sufficient to guarantee that a downstream 694038032Speter neighbor won't rewrite the address for you. 694138032Speter Add "-m" flag to makesendmail script -- this tells you what object 694238032Speter directory and Makefile it will use, but doesn't actually do 694338032Speter the make. 694438032Speter Do some additional checking on the contents of the qf file to try 694538032Speter to detect attacks against the qf file. In particular, 694638032Speter abort on any line beginning "From ", and add an "end of 694738032Speter file" line -- any data after that line is prohibited. 694838032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 694938032Speter choices. This can be overridden in the Makefile by using 695038032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 695138032Speter (to the extent that we know it) or by defining 695238032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 695338032Speter sendmail 8 to have more consistent installation instructions. 695438032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 695538032Speter of Sun Microsystems. 695638032Speter Improved symbol table hash function from Eric Wassenaar. This one 695738032Speter is at least 50% faster. 695838032Speter Fix problem that didn't notice that timeout on file open was a 695938032Speter transient error. Fix from Larry Parmelee of Cornell 696038032Speter University. 696138032Speter Allow comments (lines beginning with a `#') in files read for 696238032Speter classes. Suggested by Motonori Nakamura. 696338032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 696438032Speter of dropping out entirely. This makes testing some of the 696538032Speter name server lookups easier to deal with when there are 696638032Speter hung servers. From Motonori Nakamura. 696738032Speter Add new ${opMode} macro that is set to the current operation mode 696838032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 696938032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 697038032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 697138032Speter Kind of like queue-only mode (Odq) except it tries to avoid 697238032Speter any external service requests; for dial-on-demand hosts that 697338032Speter want to minimize DNS lookups when mail is being queued. For 697438032Speter this to work you will also have to make sure that gethostbyname 697538032Speter of your local host name does not do a DNS lookup. 697638032Speter Improved handling of "out of space" conditions from John Myers of 697738032Speter Carnegie Mellon. 697838032Speter Improved security for mailing to files on systems that have fchmod(2) 697938032Speter support. 698038032Speter Improve "cannot send message for N days" message -- now says "could 698138032Speter not send for past N days". Suggested by Tom Moore of AT&T 698238032Speter Global Information Solutions. 698338032Speter Less misleading Subject: line on messages sent to postmaster only. 698438032Speter From Motonori Nakamura. 698538032Speter Avoid duplicate error messages on bad command line flags. From 698638032Speter Motonori Nakamura. 698738032Speter Better error message for case where ruleset 0 falls off the end 698838032Speter or otherwise does not resolve to a canonical triple. 698938032Speter Fix a problem that could cause multiple bounce messages if a bad 699038032Speter address was sent along with a good address to an SMTP 699138032Speter site where that SMTP site returned a 4yz code in response 699238032Speter to the final dot of the data. Problem reported by David 699338032Speter James of British Telecom. 699438032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 699538032Speter from Alexander Dupuy of System Management ARTS. 699638032Speter Delete duplicates in MX lists -- believe it or not, there are sites 699738032Speter that list the same host twice in an MX list. This deletion 699838032Speter only works on adjacent preferences, so an MX list that 699938032Speter had A=5, B=10, A=15 would leave both As, but one that had 700038032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 700138032Speter just in case there is something weird I haven't thought of. 700238032Speter Suggested by Barry Shein of Software Tool & Die. 700338032Speter SECURITY: .forward files cannot be symbolic links. If they are, 700438032Speter a bad guy can read your private files. 700538032Speter PORTABILITY FIXES: 700638032Speter Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>. 700738032Speter System V Release 4 from Motonori Nakamura of Ritsumeikan 700838032Speter University.

This means that the 702238032Speter sizeof operator returns only multiples of 8. 702338032Speter This requires adaptation of code that really 702438032Speter deals with 32 bit or 16 bit fields, such as IP 702538032Speter addresses or nameserver fields.'' 702638032Speter DG/UX 5.4.3 from Mark T.

There is a race 710838032Speter condition between the open(...

This can 711138032Speter be used as an alternative to /bin/sh for the "prog" mailer, 711238032Speter giving the local administrator more control over what 711338032Speter programs can be run from sendmail. 711438032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 711538032Speter part of the release proper, and isn't fully supported; in 711638032Speter particular, it does not run on System V based systems and 711738032Speter never will. 711838032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 711938032Speter to allow rmail to compile on systems that don't have 712038032Speter function prototypes and systems that don't have snprintf. 712138032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 712238032Speter lists by transaction delay times so that addresses that 712338032Speter respond quickly get sent first. This is to prevent very 712438032Speter sluggish servers from delaying other peoples' mail. 712538032Speter Contributed by Tony Sanders of BSDI. 712638032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 712738032Speter of BSDI. This has a lot of comments to help people out. 712838032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 712938032Speter put this on the m4 command line. On GNU m4 (which 713038032Speter supports the __file__ primitive) you can run m4 in an 713138032Speter arbitrary directory -- use either: 713238032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 713338032Speter or 713438032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 713538032Speter On other versions of m4 that don't support __file__, you 713638032Speter can use: 713738032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 713838032Speter (Note the trailing slash on the _CF_DIR_ definition.) 713938032Speter Old versions of m4 will default to _CF_DIR_=.. for back 714038032Speter compatibility. 714138032Speter CONFIG: fix mail from <> so it will properly convert to 714238032Speter MAILER-DAEMON on local addresses. 714338032Speter CONFIG: fix code that was supposed to catch colons in host 714438032Speter names. Problem noted by John Gardiner Myers of CMU. 714538032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 714638032Speter From Paul Riddle of the University of Maryland, Baltimore 714738032Speter County. 714838032Speter CONFIG: Catch and reject "." as a host address. 714938032Speter CONFIG: Generalize domaintable to look up all domains, not 715038032Speter just unqualified ones. 715138032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 715238032Speter was never used and didn't work anyway. 715338032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 715438032Speter and d on all mailers in the UUCP class. 715538032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 715638032Speter look for an alias for "user+detail", then for "user+*", and 715738032Speter finally for "user". This is intended for forwarding mail 715838032Speter for system aliases such as root and postmaster to a 715938032Speter centralized hub. 716038032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 716138032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 716238032Speter The F=8 flag is also set on the "relay" mailer, since 716338032Speter this is expected to be another sendmail. 716438032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 716538032Speter the name of the UUCP_RELAY -- in some cases, this is the 716638032Speter wrong value (e.g., when we have local UUCP connections), 716738032Speter and this can create unreplyable addresses. From Chip 716838032Speter Rosenthal of Unicom. 716938032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 717064562Sgshapiro Received: header inserted into all messages. Suggested by 717138032Speter Gary Mills of the University of Manitoba. 717238032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 717343730Speter to get the old behavior. I did this upon observing 717438032Speter that almost everyone needed this feature, and that the 717538032Speter concept I was trying to make happen didn't work with 717638032Speter some user agents anyway. FEATURE(notsticky) still works, 717738032Speter but it is a no-op. 717838032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 717938032Speter names are sent, rather than immediately diagnosing them 718038032Speter as User Unknown. 718138032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 718238032Speter and RELAY_MAILER_ARGS to set the arguments for the 718338032Speter indicated mailers. All default to "IPC $h". Patch from 718438032Speter Larry Parmelee of Cornell University. 718538032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 718638032Speter on the client side" and F=P to get an appropriate 718738032Speter return-path. From Kimmo Suominen. 718838032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 718938032Speter as the local mailer. For addresses of the form "user+detail" 719038032Speter the "detail" part is passed to procmail via the -a flag. 719138032Speter Contributed by Kimmo Suominen. 719238032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 719338032Speter use from mailertables. This lets you execute arbitrary 719438032Speter procmail scripts. Contributed by Kimmo Suominen. 719538032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 719638032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 719738032Speter Paul Southworth of CICNet Systems Support. 719838032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 719938032Speter This causes the null return path to be rewritten as 720038032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 720138032Speter From Michael Hohmuth of Technische Universitat Dresden. 720238032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 720338032Speter list us as the best possible MX record to be treated as 720438032Speter though they were local (essentially, assume that they 720538032Speter are included in $=w). This can cause additional DNS 720638032Speter traffic, but is easier to administer if this fits your 720738032Speter local model. It does not work reliably if there are 720838032Speter multiple hosts that share the best MX preference. 720938032Speter Code contributed by John Oleynick of Rutgers. 721038032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 721138032Speter SHell) instead of /bin/sh as the program used for delivery 721238032Speter to programs. If an argument is included, it is used as 721338032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 721438032Speter assumed. 721538032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 721638032Speter size of messages to the local and procmail mailers 721738032Speter respectively. Contributed by Brad Knowles of the Defense 721838032Speter Information Systems Agency. 721938032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 722038032Speter (just like text outside of angle brackets) in order to 722138032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 722238032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 722338032Speter any real systems any more) and tweak the DOMAIN macro 722438032Speter so that it is less likely that users will accidentally use 722538032Speter the Berkeley defaults. Also, create some generic files 722638032Speter that really can be used in the real world. 722738032Speter CONFIG: Add new configuration macros to set character sets for 722838032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 722938032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 723038032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 723138032Speter The old name will still be accepted for a while at least. 723238032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 723338032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 723438032Speter As with all relays, it can be ``mailer:hostname''. Suggested 723538032Speter by Scott Hutton. 723638032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 723738032Speter by Barb Dijker of Labyrinth Computer Services. 723838032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 723938032Speter performance for large alias files, and this confused many 724038032Speter people. 724138032Speter CONFIG: Add confCF_VERSION to append local information to the 724238032Speter configuration version number displayed during SMTP startup. 724338032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 724438032Speter would only work when locally addressed. Fix from 724538032Speter Edvard Tuinder of Cistron Internet Services. 724638032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 724743730Speter "n" (CheckAliases) is set when rebuilding alias database. 724838032Speter Based on code contributed by Claude Marinier. 724938032Speter CONFIG: Allow mailertable to have values of the form 725038032Speter ``error:code message''. The ``code'' is a status code 725138032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 725238032Speter Contributed by David James <dwj@agw.bt.co.uk>. 725338032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 725438032Speter sender domains that will be replaced with the masquerade name. 725538032Speter These domains will not be treated as local, but if mail passes 725638032Speter through with sender addresses in those domains they will be 725738032Speter replaced by the masquerade name. These can also be specified 725838032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 725938032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 726038032Speter as well as the header. Substantial improvements to this 726138032Speter code were contributed by Per Hedeland. 726238032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 726338032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 726438032Speter by Kimmo Suominen. 726538032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 726638032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 726738032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 726838032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 726938032Speter UUCP addressing.

737364562Sgshapiro8.6.13/8.6.12 1996/01/25 737438032Speter SECURITY: In some cases it was still possible for an attacker to 737538032Speter insert newlines into a queue file, thus allowing access to 737638032Speter any user (except root). 737738032Speter CONFIG: no changes -- it is not a bug that the configuration 737838032Speter version number is unchanged. 737938032Speter 738064562Sgshapiro8.6.12/8.6.12 1995/03/28 738138032Speter Fix to IDENT code (it was getting the size of the reply buffer 738238032Speter too small, so nothing was ever accepted). Fix from several 738338032Speter people, including Allan Johannesen, Shane Castle of the 738438032Speter Boulder County Information Services, and Jeff Smith of 738538032Speter Warwick University (all arrived within a few hours of 738638032Speter each other!). 738738032Speter Fix a problem that could cause large jobs to run out of 738838032Speter file descriptors on systems that use vfork() rather 738938032Speter than fork(). 739038032Speter 739164562Sgshapiro8.6.11/8.6.11 1995/03/08 739238032Speter The ``possible attack'' message would be logged more often 739338032Speter than necessary if you are using Pine as a user agent. 739438032Speter The wrong host would be reported in the ``possible attack'' 739538032Speter message when attempted from IDENT. 739638032Speter In some cases the syslog buffer could be overflowed when 739738032Speter reporting the ``possible attack'' message. This can 739838032Speter cause denial of service attacks. Truncate the message 739938032Speter to 80 characters to prevent this problem. 740038032Speter When reading the IDENT response a loop is needed around the 740138032Speter read from the network to ensure that you don't get 740238032Speter partial lines. 740338032Speter Password entries without any shell listed (that is, a null 740438032Speter shell) wouldn't match as "ok". Problem noted by 740538032Speter Rob McMahon. 740638032Speter When running BIND 4.9.x a problem could occur because the 740738032Speter _res.options field is initialized differently than it 740838032Speter was historically -- this requires that sendmail call 740938032Speter res_init before it tweaks any bits. 741038032Speter Fix an incompatibility in openxscript() between the file open mode 741138032Speter and the stdio mode passed to fdopen. This caused UnixWare 741238032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 741338032Speter Novell Labs Europe. 741438032Speter Fix problem with static linking of local getopt routine when 741538032Speter using GNU's ld command. Fix from John Kennedy of 741638032Speter Cal State Chico. 741738032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 742038032Speter and Liudvikas Bukys. 742138032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 742238032Speter from Spider Boardman. 742338032Speter CONFIG: No changes (version number only, to keep it in sync 742438032Speter with the binaries). 742538032Speter 742664562Sgshapiro8.6.10/8.6.10 1995/02/10 742738032Speter SECURITY: Diagnose bogus values to some command line flags that 742838032Speter could allow trash to get into headers and qf files. 742938032Speter Validate the name of the user returned by the IDENT protocol. 743038032Speter Some systems that really dislike IDENT send intentionally 743138032Speter bogus information. Problem pointed out by Michael Bushnell 743238032Speter of the Free Software Foundation. Has some security 743338032Speter implications. 743438032Speter Fix a problem causing error messages about DNS problems when 743538032Speter the host name contained a percent sign to act oddly 743638032Speter because it was passed as a printf-style format string. 743738032Speter In some cases this could cause core dumps. 743838032Speter Avoid possible buffer overrun in returntosender() if error 743938032Speter message is quite long. From Fletcher Mattox of the 744038032Speter University of Texas. 744138032Speter Fix a problem that would silently drop "too many hops" error 744238032Speter messages if and only if you were sending to an alias. 744338032Speter From Jon Giltner of the University of Colorado and 744438032Speter Dan Harton of Oak Ridge National Laboratory. 744538032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 744638032Speter set and e->e_message was null. Fix from Bruce Nagel of 744738032Speter Data General. 744838032Speter Fix problem that can still cause df files to be left around 744938032Speter after "hop count exceeded" messages. Fix from Andrew 745038032Speter Chang and Shau-Ping Lo of SunSoft. 745138032Speter Fix a problem that can cause buffer overflows on very long 745238032Speter user names (as might occur if you piped to a program 745338032Speter with a lot of arguments). 745438032Speter Avoid returning an error and re-queueing if the host signature 745538032Speter is null; this can occur on addresses like ``user@.''. 745638032Speter Problem noted by Wesley Craig and the University of 745738032Speter Michigan. 745838032Speter Avoid possible calls to malloc(0) if MCI caching is turned 745938032Speter off. Bug fix from Pierre David of the Laboratoire 746038032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 746138032Speter Universite de Versailles - St Quentin, and Jacky 746238032Speter Thibault. 746338032Speter Make a local copy of the line being sent via senttolist() -- in 746438032Speter some cases, buffers could get trashed by map lookups 746538032Speter causing it to do unexpected things. This also simplifies 746638032Speter some of the map code. 746738032Speter CONFIG: No changes (version number only, to keep it in sync 746838032Speter with the binaries). 746938032Speter 747064562Sgshapiro8.6.9/8.6.9 1994/04/19 747138032Speter Do all mail delivery completely disconnected from any terminal. 747238032Speter This provides consistency with daemon delivery and 747338032Speter may have some security implications. 747438032Speter Make sure that malloc doesn't get called with zero size, 747538032Speter since that fails on some systems. Reported by Ed 747638032Speter Hill of the University of Iowa. 747738032Speter Fix multi-line values for $e (SMTP greeting message). Reported 747838032Speter by Mike O'Connor of Ford Motor Company. 747938032Speter Avoid syserr if no NIS domain name is defined, but the map it 748038032Speter is trying to open is optional. From Win Bent of USC. 748138032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 748238032Speter Hesiod support for UDB from Todd Miller of the University of 748338032Speter Colorado. Use "hesiod" as the service name in the U 748438032Speter option. 748538032Speter Fix a problem that failed to set the "authentic" host name (that 748638032Speter is, the one derived from the socket info) if you called 748738032Speter sendmail -bs from inetd. Based on code contributed by 748838032Speter Todd Miller (this problem was also reported by Guy Helmer 748938032Speter of Dakota State University). This also fixes a related 749038032Speter problem reported by Liudvikas Bukys of the University of 749138032Speter Rochester. 749238032Speter Parameterize "nroff -h" in all the Makefiles so people with 749338032Speter variant versions can use them easily. Suggested by 749438032Speter Peter Collinson of Hillside Systems. 749538032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 749638032Speter spaces between parameters instead of one. Reported by 749738032Speter Valdis Kletnieks of Virginia Tech. 749838032Speter Reduce the number of system calls during message collection by 749938032Speter using global timeouts around the collect() loop. This 750038032Speter code was contributed by Eric Wassenaar. 750138032Speter If the initial hostname name gathering results in a name 750238032Speter without a dot (usually caused by NIS misconfiguration) 750338032Speter and BIND is compiled in, directly access DNS to get 750438032Speter the canonical name. This should make life easier for 750538032Speter Solaris systems. If it still can't be resolved, and 750638032Speter if the name server is listed as "required", try again 750738032Speter in 30 seconds. If that also fails, exit immediately to 750838032Speter avoid bogus "config error: mail loops back to myself" 750938032Speter messages. 751038032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 751138032Speter message to explain how much space was available and 751238032Speter sound a bit less threatening. Suggested by Stan Janet 751338032Speter of the National Institute of Standards and Technology. 751438032Speter If mail is delivered to an alias that has an owner, deliver any 751538032Speter requested return-receipt immediately, and strip the 751638032Speter Return-Receipt-To: header from the subsequent message. 751738032Speter This prevents a certain class of denial of service 751838032Speter attack, arguably gives more reasonable semantics, and 751938032Speter moves things more towards what will probably become a 752038032Speter network standard. Suggested by Christopher Davis of 752138032Speter Kapor Enterprises. 752238032Speter Add a "noreceipts" privacy flag to turn off all return receipts 752338032Speter without recompiling. 752438032Speter Avoid printing ESMTP parameters as part of the error message 752538032Speter if there are errors during parsing. This change is 752638032Speter purely cosmetic. 752738032Speter Avoid sending out error messages during the collect phase of 752838032Speter SMTP; there is an MVS mailer from UCLA that gets 752938032Speter confused by this. Of course, I think it's their bug.... 753038032Speter Check for the $j macro getting undefined, losing a dot, or getting 753138032Speter lost from $=w in the daemon before accepting a connection; 753238032Speter if it is, it dumps state, prints a LOG_ALERT message, 753338032Speter and drops core for debugging. This is an attempt to 753438032Speter track down a bug that I thought was long since gone. 753538032Speter If you see this, please forward the log fragment to 753638032Speter sendmail@sendmail.ORG. 753738032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 753838032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 753938032Speter Wolfhugel. 754038032Speter Instead of trying to truncate the listen queue for the server 754138032Speter SMTP port when the load average is too high, just close 754238032Speter the port completely and reopen it later as needed. 754338032Speter This ensures that the other end gets a quick "connection 754438032Speter refused" response, and that the connection can be 754538032Speter recovered later. In particular, some socket emulations 754638032Speter seem to get confused if you tweak the listen queue 754738032Speter size around and can never start listening to connections 754838032Speter again. The down side is that someone could start up 754938032Speter another daemon process in the interim, so you could 755038032Speter have multiple daemons all not listening to connections; 755138032Speter this could in turn cause the sendmail.pid file to be 755238032Speter incorrect. A better approach might be to accept the 755338032Speter connection and give a 421 code, but that could break 755443730Speter other mailers in mysterious ways and have paging behavior 755538032Speter implications. 755638032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 755738032Speter set debugging on the wrong socket. From Eric Wassenaar. 755838032Speter When creating a df* temporary file, be sure you truncate any 755938032Speter existing data in the file -- otherwise system crashes 756038032Speter and the like could result in extra data being sent. 756138032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 756238032Speter doc directory. This includes some additional 756338032Speter information. 756438032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 756538032Speter of recipient envelope addresses. This should have been 756638032Speter handled by the $&h trick, but broke if people were 756738032Speter mixing domainized and UUCP addresses. They should 756838032Speter probably have converted all the way over to uucp-uudom 756938032Speter instead of uucp-{new,old}, but the failure mode was to 757038032Speter loop the mail, which was bad news. 757138032Speter Portability fixes: 757238032Speter Newer BSDI systems (several people). 757338032Speter Older BSDI systems from Christophe Wolfhugel. 757438032Speter Intergraph CLIX, from Paul Southworth of CICNet. 757538032Speter UnixWare, from Evan Champion. 757638032Speter NetBSD from Adam Glass. 757738032Speter Solaris from Quentin Campbell of the University of 757838032Speter Newcastle upon Tyne. 757938032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 758038032Speter Corporation. 758138032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 758238032Speter SunOS (it has setsid() and setvbuf() calls) from 758338032Speter Jonathan Kamens of OpenVision Technologies. 758438032Speter HP-UX from Tor Lillqvist. 758538032Speter New Files: 758638032Speter src/Makefile.CLIX 758738032Speter src/Makefile.NCR3000 758838032Speter doc/changes/Makefile 758938032Speter doc/changes/changes.me 759038032Speter doc/changes/changes.ps 759138032Speter 759264562Sgshapiro8.6.8/8.6.6 1994/03/21 759338032Speter SECURITY: it was possible to read any file as root using the 759438032Speter E (error message) option. Reported by Richard Jones; 759538032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 759638032Speter 759764562Sgshapiro8.6.7/8.6.6 1994/03/14 759838032Speter SECURITY: it was possible to get root access by using weird 759938032Speter values to the -d flag. Thanks to Alain Durand of 760038032Speter INRIA for forwarding me the notice from the bugtraq 760138032Speter list. 760238032Speter 760364562Sgshapiro8.6.6/8.6.6 1994/03/13 760438032Speter SECURITY: the ability to give files away on System V-based 760538032Speter systems proved dangerous -- don't run as the owner 760638032Speter of a :include: file on a system that allows giveaways. 760738032Speter Unfortunately, this also applies to determining a 760838032Speter valid shell. 760938032Speter IMPORTANT: Previous versions weren't expiring old connections 761038032Speter in the connection cache for a long time under some 761138032Speter circumstances. This could result in resource exhaustion, 761238032Speter both at your end and at the other end. This checks the 761338032Speter connections for timeouts much more frequently. From 761438032Speter Doug Anderson of NCSC. 761538032Speter Fix a glitch that snuck in that caused programs to be run as 761638032Speter the sender instead of the recipient if the mail was 761738032Speter from a local user to another local user. From 761838032Speter Motonori Nakamura of Kyoto University. 761938032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 762038032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 762138032Speter Bryan Costales of ICSI. 762238032Speter Change the method used to declare the "statfs" availability; 762338032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 762438032Speter tweaking in conf.c, there is a single #define called 762538032Speter SFS_TYPE which takes on one of six values (SFS_NONE 762638032Speter for no statfs availability, SFS_USTAT for the ustat(2) 762738032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 762838032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 762938032Speter statfs(2) call with the declarations in <sys/vfs.h>, 763038032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 763138032Speter Fix glitch in NetInfo support that could return garbage if 763238032Speter there was no "/locations/sendmail" property. From 763338032Speter David Meyer of the University of Virginia. 763438032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 763538032Speter to allow Linux to turn it off even though it is a 763638032Speter BSD-like system. 763738032Speter Allow setting of "ident" timeout to zero to turn off the ident 763838032Speter protocol entirely. 763938032Speter Make 7-bit stripping local to a connection (instead of to a 764038032Speter mailer); this allows you to specify that SMTP is a 764138032Speter 7-bit channel, but revert to 8-bit should it advertise 764238032Speter that it supports 8BITMIME. You still have to specify 764338032Speter mailer flag 7 to get this stripping at all. 764438032Speter Improve makesendmail script so it handles more cases automatically. 764538032Speter Tighten up restrictions on taking ownership of :include: files 764638032Speter to avoid problems on systems that allow you to give away 764738032Speter files. 764838032Speter Fix a problem that made it impossible to rebuild the alias 764938032Speter file if it was on a read-only file system. From 765038032Speter Harry Edmon of the University of Washington. 765138032Speter Improve MX randomization function. From John Gardiner Myers 765238032Speter of CMU. 765338032Speter Fix a minor glitch causing a bogus message to be printed (used 765438032Speter %s instead of %d in a printf string for the line number) 765538032Speter when a bad queue file was read. From Harry Edmon. 765638032Speter Allow $s to remain NULL on locally generated mail. I'm not 765738032Speter sure this is necessary, but a lot of people have complained 765838032Speter about it, and there is a legitimate question as to whether 765938032Speter "localhost" is legal as an 822-style domain. 766038032Speter Fix a problem with very short line lengths (mailer L= flag) in 766138032Speter headers. This causes a leading space to be added onto 766238032Speter continuation lines (including in the body!), and also 766338032Speter tries to wrap headers containing addresses (From:, To:, 766438032Speter etc) intelligently at the shorter line lengths. Problem 766538032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 766638032Speter Log the real user name when logging syserrs, since these can have 766738032Speter security implications. Suggested by several people. 766838032Speter Fix address logging of cached connections -- it used to always 766938032Speter log the numeric address as zero. This is a somewhat 767038032Speter bogus implementation in that it does an extra system 767138032Speter call, but it should be an inexpensive one. Fix from 767238032Speter Motonori Nakamura. 767338032Speter Tighten up handling of short syslog buffers even more -- there 767438032Speter were cases where the outgoing relay= name was too long 767538032Speter to share a line with delay= and mailer= logging. 767638032Speter Limit the overhead on split envelopes to one open file descriptor 767738032Speter per envelope -- previously the overhead was three 767838032Speter descriptors. This was in response to a problem reported 767938032Speter by P{r (Pell) Emanuelsson. 768038032Speter Fixes to better handle the case of unexpected connection closes; 768138032Speter this redirects the output to the transcript so the info 768238032Speter is not lost. From Eric Wassenaar. 768338032Speter Fix potential string overrun if you macro evaluate a string that 768438032Speter has a naked $ at the end. Problem noted by James Matheson 768538032Speter <jmrm@eng.cam.ac.uk>. 768638032Speter Make default error number on $#error messages 553 (``Requested 768738032Speter action not taken: mailbox name not allowed'') instead of 768838032Speter 501 (``Syntax error in parameters or arguments'') to 768938032Speter avoid bogus "protocol error" messages. 769038032Speter Strip off any existing trailing dot on names during $[ ... $] 769138032Speter lookup. This prevents it from ending up with two dots 769238032Speter on the end of dot terminated names. From Wesley Craig 769338032Speter of the University of Michigan and Bryan Costales of ICSI. 769438032Speter Clean up file class reading so that the debugging information is 769538032Speter more informative. It hadn't been using setclass, so you 769638032Speter didn't see the class items being added. 769738032Speter Avoid core dump if you are running a version of sendmail where 769838032Speter NIS is compiled in, and you specify an NIS map, but 769938032Speter NIS is not running. Fix from John Oleynick of 770038032Speter Rutgers. 770138032Speter Diagnose bizarre case where res_search returns a failure value, 770238032Speter but sets h_errno to a success value. 770338032Speter Make sure that "too many hops" messages are considered important 770438032Speter enough to send an error to the Postmaster (that is, the 770538032Speter address specified in the P option). This fix should 770638032Speter help problems that cause the df file to be left around 770738032Speter sometimes -- unfortunately, I can't seem to reproduce 770838032Speter the problem myself. 770938032Speter Avoid core dump (null pointer reference) on EXPN command; this 771038032Speter only occurred if your log level was set to 10 or higher 771138032Speter and the target account was an alias or had a .forward file. 771238032Speter Problem noted by Janne Himanka. 771338032Speter Avoid "denial of service" attacks by someone who is flooding your 771438032Speter SMTP port with bad commands by shutting the connection 771538032Speter after 25 bad commands are issued. From Kyle Jones of 771638032Speter UUNET. 771738032Speter Fix core dump on error messages with very long "to" buffers; 771838032Speter fmtmsg overflows the message buffer. Fixed by trimming 771938032Speter the to address to 203 characters. Problem reported by 772038032Speter John Oleynick. 772138032Speter Fix configuration for HASFLOCK -- there were some spots where 772238032Speter a #ifndef was incorrectly #ifdef. Pointed out by 772338032Speter George Baltz of the University of Maryland. 772438032Speter Fix a typo in savemail() that could cause the error message To: 772538032Speter lists to be incorrect in some places. From Motonori 772638032Speter Nakamura. 772738032Speter Fix a glitch that can cause duplicate error messages on split 772838032Speter envelopes where an address on one of the lists has a 772938032Speter name server failure. Fix from Voradesh Yenbut of the 773038032Speter University of Washington. 773138032Speter Fix possible bogus pointer reference on ESMTP parameters that 773238032Speter don't have an ``=value'' part. 773338032Speter CNAME loops caused an error message to be generated, but also 773438032Speter re-queued the message. Changed to just re-queue the 773538032Speter message (it's really hard to just bounce it because 773638032Speter of the weird way the name server works in the presence 773738032Speter of CNAME loops). Problem noted by James M.R.Matheson 773838032Speter of Cambridge University. 773938032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 774038032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 774138032Speter user name. Suggested by Andreas Stolcke of ICSI. 774238032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 774338032Speter override it easily in the Makefile -- that is, you can 774438032Speter turn it off using -DNAMED_BIND=0. 774538032Speter If a gethostbyname(...) of an address with a trailing dot fails, 774638032Speter try it without the trailing dot. This is because if 774738032Speter you have a version of gethostbyname() that falls back 774838032Speter to NIS or the /etc/hosts file it will fail to find 774938032Speter perfectly reasonable names that just don't happen to 775038032Speter be dot terminated in the hosts file. You don't want to 775138032Speter strip the dot first though because we're trying to ensure 775238032Speter that country names that match one of your subdomains get 775338032Speter a chance. 775438032Speter PRALIASES: fix bogus output on non-null-terminated strings. 775538032Speter From Bill Gianopoulos of Raytheon. 775638032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 775738032Speter This was in code intended to only catch the self-literal 775838032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 775938032Speter IP address), but the code was broken. However, it will 776038032Speter still do this if $M is defined; this is necessary to 776138032Speter get client configurations to work (sigh). Note that this 776238032Speter means that $M overrides :mailname entries in the user 776338032Speter database! Problem noted by Paul Southworth. 776438032Speter CONFIG: Fix definition of Solaris help file location. From 776538032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 776638032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 776738032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 776838032Speter and USENET_MAILER_MAX to tweak the maximum message 776938032Speter size for various mailers. 777038032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 777138032Speter instead of assuming that it is "inews" for consistency 777238032Speter with other mailers. From Michael Corrigan of UC San Diego. 777338032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 777438032Speter qualify the address in the SMTP envelope as user@{relay|hub} 777538032Speter instead of user@$j. From Bill Wisner of The Well. 777638032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 777738032Speter CONFIG: Don't turn off case mapping of user names in the local 777838032Speter mailer for IRIX. This was different than most every other 777938032Speter system. 778038032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 778138032Speter envelope. Noted by Thierry Besancon 778238032Speter <besancon@excalibur.ens.fr>. 778338032Speter CONFIG: Don't include -z by default on uux line -- most systems 778438032Speter don't want it set by default. Pointed out by Philippe 778538032Speter Michel of Thomson CSF. 778638032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 778738032Speter host name was foo.bar.ray.com and you matched against 778838032Speter ".ray.com", the old implementation bound %1 to "bar" 778938032Speter instead of "foo.bar". Also, allow "." in the mailertable 779038032Speter to match anything -- essentially, take over SMART_HOST. 779138032Speter This also moves matching of explicit local host names 779238032Speter before the mailertable so they don't have to be special 779338032Speter cased in the mailertable data. Reported by Bill 779438032Speter Gianopoulos of Raytheon; the fix for the %1 binding 779538032Speter problem was contributed by Nicholas Comanos of the 779638032Speter University of Sydney. 779738032Speter CONFIG: Don't include "root" in class $=L (users to deliver 779838032Speter locally, even if a hub or relay exists) by default. 779938032Speter This is because of the known bug where definition of 780038032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 780138032Speter both and deliver into the local mailbox. 780238032Speter CONFIG: Move up bitdomain and uudomain handling so that they 780338032Speter are done before .UUCP class matching; uudomain was 780438032Speter reported as ineffective before. This also frees up 780538032Speter diversion 8 for future use. Problem reported by Kimmo 780638032Speter Suominen. 780738032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 780838032Speter into host names. As pointed out by Jonathan Kamens, 780938032Speter these are often used because either the forward or reverse 781038032Speter mapping is broken; this translation makes it broken again. 781138032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 781238032Speter Suominen. 781338032Speter Portability fixes: 781438032Speter Unicos from David L. Kensiski of Sterling Software. 781538032Speter DomainOS from Don Lewis of Silicon Systems. 781638032Speter GNU m4 1.0.3 from Karst Koymans of Utrecht University. 781738032Speter Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. 781838032Speter NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. 781938032Speter BSD/386 from Tony Sanders of BSDI. 782038032Speter Apollo from Eric Wassenaar. 782138032Speter DGUX from Doug Anderson. 782238032Speter Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. 782338032Speter NEW FILES: 782438032Speter src/Makefile.DomainOS 782538032Speter src/Makefile.PTX 782638032Speter src/Makefile.SunOS.5.1 782738032Speter src/Makefile.SunOS.5.2 782838032Speter src/Makefile.SunOS.5.x 782938032Speter src/mailq.1 783038032Speter cf/ostype/domainos.m4 783138032Speter doc/op/Makefile 783238032Speter doc/intro/Makefile 783338032Speter doc/usenix/Makefile 783438032Speter 783564562Sgshapiro8.6.5/8.6.5 1994/01/13 783638032Speter Security fix: /.forward could be owned by anyone (the test 783738032Speter to allow root to own any file was backwards). From 783838032Speter Bob Campbell at U.C. Berkeley. 783938032Speter Security fix: group ids were not completely set when programs 784038032Speter were invoked. This caused programs to have group 784138032Speter permissions they should not have had (usually group 784238032Speter daemon instead of their own group). In particular, 784338032Speter Perl scripts would refuse to run. 784438032Speter Security: check to make sure files that are written are not 784538032Speter symbolic links (at least under some circumstances). 784638032Speter Although this does not respond to a specific known 784738032Speter attack, it's just a good idea. Suggested by 784838032Speter Christian Wettergren. 784938032Speter Security fix: if a user had an NFS mounted home directory on 785038032Speter a system with a restricted shell listed in their 785138032Speter /etc/passwd entry, they could still execute any 785238032Speter program by putting that in their .forward file. 785338032Speter This fix prevents that by insisting that their shell 785438032Speter appear in /etc/shells before allowing a .forward to 785538032Speter execute a program or write a file. You can disable 785638032Speter this by putting "*" in /etc/shells. It also won't 785738032Speter permit world-writable :include: files to reference 785838032Speter programs or files (there's no way to disable this). 785943730Speter These behaviors are only one level deep -- for 786038032Speter example, it is legal for a world-writable :include: 786138032Speter file to reference an alias that writes a file, on 786238032Speter the assumption that the alias file is well controlled. 786338032Speter Security fix: root was not treated suspiciously enough when 786438032Speter looking into subdirectories. This would potentially 786538032Speter allow a cracker to examine files that were publicly 786638032Speter readable but in a non-publicly searchable directory. 786738032Speter Fix a problem that causes an error on QUIT on a cached 786838032Speter connection to create problems on the current job. 786938032Speter These are typically unrelated, so errors occur in 787038032Speter the wrong place. 787138032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 787238032Speter runs more responsive to load average, and fixes a 787338032Speter problem that ignored the load average in locally 787438032Speter generated mail. From Eric Wassenaar. 787538032Speter Fix possible core dump on aliases with null LHS. From 787638032Speter John Orthoefer of BB&N. 787738032Speter Revert to using flock() whenever possible -- there are just 787838032Speter too many bugs in fcntl() locking, particularly over 787938032Speter NFS, that cause sendmail to fail in perverse ways. 788038032Speter Fix a bug that causes the connection cache to get confused 788138032Speter when sending error messages. This resulted in 788238032Speter "unexpected close" messages. It should fix itself 788338032Speter on the following queue run. Problem noted by 788438032Speter Liudvikas Bukys of the University of Rochester. 788538032Speter Include $k in $=k as documented in the Install & Op Guide. 788638032Speter This seems odd, but it was documented.... From 788738032Speter Michael Corrigan of UCSD. 788838032Speter Fix problem that caused :include:s from alias files to be 788938032Speter forced to be owned by root instead of daemon 789038032Speter (actually DefUid). From Tim Irvin. 789138032Speter Diagnose unrecognized I option values -- from Mortin Forssen 789238032Speter of the Chalmers University of Technology. 789338032Speter Make "error" mailer work consistently when there is no error 789438032Speter code associated with it -- previously it returned OK 789538032Speter even though there was a real problem. Now it assumes 789638032Speter EX_UNAVAILABLE. 789738032Speter Fix bug that caused the last header line of messages that had 789838032Speter no body and which were terminated with EOF instead of 789938032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 790038032Speter Fix core dump on SMTP mail to programs that failed -- it tried 790138032Speter to go to a "next MX host" when none existed, causing 790238032Speter a core dump. From der Mouse at McGill University. 790338032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 790438032Speter this makes it easier to turn it off (using 790538032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 790638032Speter Fix YP_MASTER_NAME store to use the unupdated result of 790738032Speter gethostname() (instead of myhostname(), which tries 790838032Speter to fully qualify the name) to be consistent with 790938032Speter SunOS. If your hostname is unqualified, this fixes 791038032Speter transfers to slave servers. Bug noted by Keith 791138032Speter McMillan of Ameritech Services, Inc. 791238032Speter Fix Ultrix problem: gethostbyname() can return a very large 791338032Speter (> 500) h_length field, which causes the sockaddr 791438032Speter to be trashed. Use the size of the sockaddr instead. 791538032Speter Fix from Bob Manson of Ohio State. 791638032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 791738032Speter defined -- this confuses gethostbyname on hosts 791838032Speter file lookups, which doesn't understand the trailing 791938032Speter dot convention. 792038032Speter Log SMTP server subprocesses that die with a signal instead 792138032Speter of from a clean exit. 792238032Speter If you don't have option "I" set, don't assume that a DNS 792338032Speter "host unknown" message is authoritative -- it 792438032Speter might still be found in /etc/hosts. 792538032Speter Fix a problem that would cause Deferred: messages to be sent 792638032Speter as the subject of an error message, even though the 792738032Speter actual cause of a message was more severe than that. 792838032Speter Problem noted by Chris Seabrook of OSSI. 792938032Speter Fix race condition in DBM alias file locking. From Kyle 793038032Speter Jones of UUNET. 793138032Speter Limit delivery syslog line length to avoid bugs in some 793238032Speter versions of syslog(3). This adds a new compile time 793338032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 793438032Speter University, which is in turn derived from IDA. 793538032Speter Fix quotes inside of comments in addresses -- previously 793638032Speter it insisted that they be balanced, but the 822 spec 793738032Speter says that they should be ignored. 793838032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 793938032Speter debugging). This also evaluates ruleset 89, if set 794038032Speter (with the null input), and logs the result. This 794138032Speter should be used sparingly, since the rewrite process 794238032Speter is not reentrant. 794338032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 794438032Speter documented in the Bat Book. 794538032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 794638032Speter return an error message and did not requeue the message. 794738032Speter Fix based on code from Roland Dirlewanger of 794838032Speter Reseau Regional Aquarel, Bordeaux, France. 794938032Speter Fix a problem that caused a seg fault if you got a 421 error 795038032Speter code during some parts of connection initialization. 795138032Speter I've only seen this when talking to buggy mailers on 795238032Speter the other end, but it shouldn't give a seg fault in 795338032Speter any case. From Amir Plivatsky. 795438032Speter Fix core dump caused by a ruleset call that returns null. 795538032Speter Fix from Bryan Costales of ICSI. 795638032Speter Full-Name: field was being ignored. Fix from Motonori Nakamura 795738032Speter of Kyoto University. 795838032Speter Fix a possible problem with very long input lines in setproctitle. 795938032Speter From P{r Emanuelsson. 796038032Speter Avoid putting "This is a warning message" out on return receipts. 796138032Speter Suggested by Douglas Anderson. 796238032Speter Detect loops caused by recursive ruleset calls. Suggested by 796338032Speter Bryan Costales. 796438032Speter Initialize non-alias maps during alias rebuilds -- they may be 796538032Speter needed for parsing. Problem noted by Douglas Anderson. 796638032Speter Log sender address even if no message was collected in SMTP 796738032Speter (e.g., if all RCPTs failed). Suggested by Motonori 796838032Speter Nakamura. 796938032Speter Don't reflect the owner-list contents into the envelope sender 797038032Speter address if the value contains ", :, /, or | (to avoid 797138032Speter illegal addresses appearing there). 797238032Speter Efficiency hack for toktype macro -- from Craig Partridge of 797338032Speter BB&N. 797438032Speter Clean up DNS error printing so that a host name is always 797538032Speter included. 797638032Speter Remember to set $i during queue runs. Reported by Stephen 797738032Speter Campbell of Dartmouth University. 797838032Speter If the environment variable HOSTALIASES is set, use it during 797938032Speter canonification as the name of a file with per-user host 798038032Speter translations so that headers are properly mapped. Reported 798138032Speter by Anne Bennett of Concordia University. 798238032Speter Avoid printing misleading error message if SMTP mailer (not 798338032Speter using [IPC]) should die on a core dump. 798438032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 798538032Speter by the other end closing the connection. From 798638032Speter Dave Morrison of Oracle. 798738032Speter Improve several of the error messages printed by "mailq" 798838032Speter to include a host name or other useful information. 798938032Speter Add NetInfo preliminary support for NeXT systems. From Vince 799038032Speter DeMarco. 799138032Speter Fix a glitch that sometimes caused :include:s that pointed to 799238032Speter NFS filesystems that were down to give an "aliasing/ 799338032Speter forwarding loop broken" message instead of queueing 799438032Speter the message for retry. Noted by William C Fenner of 799538032Speter the NRL Connection Machine Facility. 799638032Speter Fix a problem that could cause a core dump if the input sequence 799738032Speter had (or somehow acquired) a \231 character. 799838032Speter Make sure that route-addrs always have <angle brackets> around 799938032Speter them in non-SMTP envelopes (SMTP envelopes already do 800038032Speter this properly). 800138032Speter Avoid weird headers on unbalanced punctuation of the form: 800238032Speter ``Joe User <user)'' -- this caused reference to the 800338032Speter null macro. Fix from Rick McCarty of IO.COM. 800438032Speter Fix a problem that caused an alias "user: user@local.host" to 800538032Speter not have the QNOTREMOTE bit set; this caused configs 800638032Speter to act as if FEATURE(notsticky) was defined even when 800738032Speter it was not. The effect of the problem was to make it 800838032Speter very hard to to set up satellite sites that had a few 800938032Speter local accounts, with everything else forwarded to a 801038032Speter corporate hub. Reported by Detlef Drewanz of the 801138032Speter University of Rostock and Mark Frost of NCD. 801238032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 801338032Speter addresses. This is more efficient (fewer name server 801438032Speter calls) and fixes certain unusual configurations, such 801538032Speter as those that have ruleset 4 do something that is 801638032Speter non-idempotent unless a mailer-specific ruleset did 801738032Speter something else. Problem reported by Brian J. Coan 801838032Speter of the Institute for Global Communications. 801938032Speter Fix the "obsolete argument" routine in main to better understand 802038032Speter new arguments. For example, if you used ``sendmail 802138032Speter -C config -v -q'' it would choke on the -q because 802238032Speter the -C would stop looking for old-format arguments. 802338032Speter Fix the code that was intended to allow two users to forward their 802438032Speter mail to the same program and have them appear unique. 802538032Speter Portability fixes for: 802638032Speter SCO UNIX from Murray Kucherawy. 802738032Speter SCO Open Server 3.2v4 from Philippe Brand. 802838032Speter System V Release 4 from Rick Ellis and others. 802938032Speter OSF/1 from Steve Campbell. 803038032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 803138032Speter of Stoner Associates. 803238032Speter Motorola SysV88 from Kevin Johnson of Motorola. 803338032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 804738032Speter of the config file has moved to /usr/lib 804838032Speter to match the HP-UX version of sendmail. 804938032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 805038032Speter since this is intended only for internal use, the 805138032Speter usual RFC 821/822/1123 rules can be relaxed. The 805238032Speter main point of this is to avoid munging (ugh) UUCP 805338032Speter addresses when relaying internally. 805438032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 805538032Speter syntax addresses delivered via UUCP. Solution 805638032Speter provided by Peter Wemm. 805738032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 805838032Speter zero; it caused double @ signs in addresses. From 805938032Speter Irving Reid of the University of Toronto. 806038032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 806138032Speter from Markku Toijala of ICL Personal Systems Oy. 806238032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 806338032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 806438032Speter that made it hard to recognize your own pseudodomain 806538032Speter names. 806638032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 806738032Speter rather than letting them get "local configuration 806838032Speter error"s. Problem noted by John Gardiner Myers. 806938032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 807038032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 807138032Speter has uucp-dom semantics but old UUCP syntax. This 807238032Speter also permits "uucp-old" as an alias for "uucp" and 807338032Speter "uucp-new" as a synonym for "suucp" for consistency. 807438032Speter CONFIG: add POP mailer support (from Kimmo Suominen 807538032Speter <kim@grendel.lut.fi>). 807638032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 807738032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 807838032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 807938032Speter was set; it would get an additional @masquerade.host 808038032Speter added to the address. Problem noted by Peter Wan 808138032Speter of Georgia Tech. 808238032Speter CONFIG: make sure that the local UUCP name is in $=w. From 808338032Speter Jim Murray of Stratus. 808438032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 808538032Speter mailer flag. Briefly, if you are sending to host 808638032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 808738032Speter "foo!baz" remains "foo!baz", and anything else has 808838032Speter the local name prepended. 808938032Speter CONFIG: portability fixes for HP-UX. 809038032Speter DOC: several minor problems fixed in the Install & Op Guide. 809138032Speter MAKEMAP: fix core dump problem on lines that are too long or 809238032Speter which lack newline.

This 812838032Speter makes quite certain that crackers can't use this 812938032Speter class of attack. 813038032Speter Reliability Fix: check return value from fclose() and fsync() 813138032Speter in a few critical places. 813238032Speter Minor problem in initsys() that reversed a condition for 813338032Speter redirecting the output channel on queue runs. It's 813438032Speter not clear this code even does anything. From Eric 813538032Speter Wassenaar of the Dutch National Institute for Nuclear 813638032Speter and High-Energy Physics. 813738032Speter Fix some problems that caused queue runs to do "too much work", 813838032Speter such as double-reading the Errors-To: header. From 813938032Speter Eric Wassenaar. 814038032Speter Error messages on writing the temporary file (including the 814138032Speter data file) were getting suppressed in SMTP -- this 814238032Speter fix causes them to be properly reported. From Eric 814338032Speter Wassenaar. 814438032Speter Some changes to support AF_UNIX sockets -- this will only 814538032Speter really become relevant in the next release, but some 814638032Speter people need it for local patches. From Michael 814738032Speter Corrigan of UC San Diego. 814838032Speter Use dynamically allocated memory (instead of static buffers) 814938032Speter for macros defined in initsys() and settime(); since 815038032Speter these can have different values depending on which 815138032Speter envelope they are in. From Eric Wassenaar. 815238032Speter Improve logging to show ctladdr on to= logging; this tells you 815338032Speter what uid/gid processes ran as. 815438032Speter Fix a problem that caused error messages to be discarded if 815538032Speter the sender address was unparseable for some reason; 815638032Speter this was supposed to fall back to the "return to 815738032Speter postmaster" case. 815838032Speter Improve aliaswait backoff algorithm. 815938032Speter Portability patches for Linux (8.6.3 required another header 816038032Speter file) (from Karl London) and SCO UNIX. 816138032Speter CONFIG: patch prog mailer to not strip host name off of envelope 816238032Speter addresses (so that it matches local again). From 816338032Speter Christopher Davis. 816438032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 816538032Speter this prevents uux from seeing lines with null names like 816638032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 816738032Speter Nakamura of Kyoto University. 816838032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 816938032Speter it shouldn't fail miserably.

It was previously listed as 818238032Speter the current time. Bug reported by Eric Hagberg of 818338032Speter Cornell University Medical College. 818438032Speter If there is an error when writing the body of a message, 818538032Speter don't send the trailing dot and wait for a response 818638032Speter in sender SMTP, as this could cause the connection to 818738032Speter hang up under some bizarre circumstances. From Eric 818838032Speter Wassenaar. 818938032Speter Fix some server SMTP synchronization problems caused when 819038032Speter connections fail during message collection. From 819138032Speter Eric Wassenaar. 819238032Speter Fix a problem that can cause srvrsmtp to reject mail if the 819338032Speter name server is down -- it accepts the RCPT but rejects 819438032Speter the DATA command. Problem reported by Jim Murray of 819538032Speter Stratus. 819638032Speter Fix a problem that can cause core dumps if the config file 819738032Speter incorrectly resolves to a null hostname. Reported by 819838032Speter Allan Johannesen of WPI. 819938032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 820038032Speter by non-root users were not put into 820138032Speter X-Authentication-Warning:s as intended because the 820243730Speter config file hadn't set the PrivacyOptions yet. Fix 820338032Speter from Sven-Ove Westberg of the University of Lulea. 820438032Speter Under very odd circumstances, the alias file rebuild code 820538032Speter could get confused as to whether a database was 820638032Speter open or not. 820738032Speter Check "vendor code" on the end of V lines -- this is 820838032Speter intended to provide a hook for vendor-specific 820938032Speter configuration syntax. (This is a "new feature", 821038032Speter but I've made an exception to my rule in a belief 821138032Speter that this is a highly exceptional case.) 821238032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 821338032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 821438032Speter (from Jon Forrest of UC Berkeley) 821538032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 821638032Speter 821764562Sgshapiro8.6.1/8.6 1993/10/08 821838032Speter Portability fixes for A/UX and Encore UMAX V. 821938032Speter Fix error message handling -- if you had a name server down 822038032Speter causing an error during parsing, that message was never 822138032Speter propagated to the queue file. 822238032Speter 822364562Sgshapiro8.6/8.6 1993/10/05 822438032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 822538032Speter conf.h (other systems have the same bug). 822638032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 822738032Speter getdtablesize() instead of sysconf(); a disturbingly 822838032Speter large number of systems defined _SC_OPEN_MAX in the 822938032Speter header files but don't have the syscall. 823038032Speter Another patch to really truly ignore MX records in getcanonname 823138032Speter if trymx == FALSE. 823238032Speter Fix problem that caused the "250 IAA25499 Message accepted for 823338032Speter delivery" message to be omitted if there was an error 823438032Speter in the header of the message (e.g., a bad Errors-To: 823538032Speter line). Pointed out by Michael Corrigan of UCSD. 823638032Speter Announce name of host we are chatting when we get errors; this 823738032Speter is an IDA-ism suggested by Christophe Wolfhugel. 823838032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 823938032Speter Australian Artificial Intelligence Institute), SCO Unix 824038032Speter (from Murray Kucherawy of Hookup Communication Corp.), 824138032Speter NeXT (from Vince DeMarco and myself), Linux (from 824238032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 824338032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 824438032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 824538032Speter Some changes to get around gcc optimizer bugs. From Takahiro 824638032Speter Kanbe. 824738032Speter Fix error recovery in queueup if another tf file of the same 824838032Speter name already exists. Problem stumbled over by Bill 824938032Speter Wisner of The Well. 825038032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 825138032Speter Problem noted by Keith McMillan of Ameritech Services. 825238032Speter Deal with group permissions properly when opening .forward and 825338032Speter :include: files. This relaxes the 8.1C restrictions 825438032Speter slightly more. This includes proper setting of groups 825538032Speter when reading :include: files, allowing you to read some 825638032Speter files that you should be able to read but have previously 825738032Speter been denied unless you owned them or they had "other" 825838032Speter read permission. 825938032Speter Make certain that $j is in $=w (after the .cf is read) so that 826038032Speter if the user is forced to override some silly system, 826138032Speter MX suppression will still work. 826238032Speter Fix a couple of efficiency problems where newstr was double- 826338032Speter calling expensive routines. In at least one case, it 826438032Speter wasn't guaranteed that they would always return the 826538032Speter same result. Problem noted by Christophe Wolfhugel. 826638032Speter Fix null pointer dereference in putoutmsg -- only on an error 826738032Speter condition from a non-SMTP mailer. From Motonori 826838032Speter Nakamura. 826938032Speter Macro expand "C" line class definitions before scanning so that 827038032Speter "CX $Z" works. 827138032Speter Fix problem that caused error message to be sent while still 827238032Speter trying to send the original message if the connection 827338032Speter is closed during a DATA command after getting an error 827438032Speter on an RCPT command (pretty obscure). Problem reported 827538032Speter by John Myers of CMU. 827638032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 827738032Speter term bug. 827838032Speter Fix a nasty bug causing core dumps when returning the "warning: 827938032Speter cannot deliver for N hours -- will keep trying" message; 828043730Speter it only occurred if you had PostmasterCopy set and 828138032Speter only on some architectures. Although sendmail would 828238032Speter keep trying, it would send error messages on each 828338032Speter queue interval. This is an important fix. 828438032Speter Allow u and g options to take user and group names respectively. 828538032Speter Don't do a chdir into the queue directory in -bt mode to make 828638032Speter ruleset testing a bit easier. 828738032Speter Don't allow users to turn off logging (using -oL) on the command 828838032Speter line -- command line can only raise, not lower, logging 828938032Speter level. 829038032Speter Set $u to the original recipient on the SMTP transaction or on 829138032Speter the command line. This is only done if there is exactly 829238032Speter one recipient. Technically, this does not meet the 829338032Speter specs, because it does not guarantee a domain on the 829438032Speter address. 829538032Speter Fix a problem that dumped error messages on bad addresses if 829638032Speter you used the -t flag. Problem noted by Josh Smith of 829738032Speter Harvey Mudd College. 829838032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 829938032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 830038032Speter avoid the problem of people who use angle brackets in 830138032Speter their full name information. 830238032Speter Fix a null pointer dereference if you set option "l", have 830338032Speter an Errors-To: header in the message, and have Errors-To: 830438032Speter defined in the config file H lines. From J.R. Oldroyd. 830538032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 830638032Speter wrong when compiling. Suggested by Rick McCarty of TI. 830738032Speter Fix a problem that could pass negative SIZE parameter if the 830838032Speter df file got lost; this would cause servers to always 830938032Speter give a temporary failure, making the problem even worse. 831038032Speter Problem noted by Allan Johannesen of WPI. 831138032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 831238032Speter protocol timeouts (30s default). Requested by Murray 831338032Speter Kucherawy of HookUp Communication Corp. to handle bogus 831438032Speter PC TCP/IP implementations. 831538032Speter Change $w default definition to be just the first component of 831638032Speter the domain name on config level 5. The $j macro defaults 831738032Speter to the FQDN; $m remains as before. This lets well-behaved 831838032Speter config files use any of the short, long, or subdomain 831938032Speter names. 832038032Speter Add makesendmail script in src to try to automate multi-architecture 832138032Speter builds. I know, this is sub-optimal, but it is still 832238032Speter helpful. 832338032Speter Fix very obscure race condition that can cause a queue run to 832438032Speter get a queue file for an already completed job. This 832538032Speter problem has existed for years. Problem noted by the 832638032Speter long suffering Allan Johannesen of WPI. 832738032Speter Fix a problem that caused the raw sender name to be passed to 832838032Speter udbsender instead of the canonified name -- this caused 832938032Speter it to sometimes miss records that it should have found. 833038032Speter Relax check of name on HELO packet so that a program using -bs 833138032Speter that claims to be itself works properly. 833238032Speter Restore rewriting of $: part of address through 2, R, 4 in 833338032Speter buildaddr -- this requires passing a lot of flags to get 833438032Speter it right. Unlike old versions, this ONLY rewrites 833538032Speter recipient addresses, not sender addresses. 833638032Speter Fix a bug that caused core dumps in config files that cannot 833738032Speter resolve /file/name style addresses. Fix from Jonathan 833838032Speter Kamens of OpenVision Technologies. 833938032Speter Fix problem with fcntl locking that can cause error returns to 834038032Speter be lost if the lock is lost; this required fully 834138032Speter queueing everything, dropping the envelope (so errors 834238032Speter would get returned), and then re-reading the queue from 834338032Speter scratch. 834438032Speter Fix a problem that caused aliases that redefine an otherwise 834538032Speter true address to still send to the original address 834638032Speter if and only if the alias failed in certain bizarre 834738032Speter ways (e.g, if they pointed at a list:; syntax address). 834838032Speter Problem pointed out by Jonathan Kamens. 834938032Speter Remove support for frozen configuration files. They caused 835038032Speter more trouble than it was worth. 835138032Speter Fix problem that can cause error messages to get ignored when 835238032Speter using both -odb and -t flags. Problem noted by Rob 835338032Speter McNicholas at U.C. Berkeley. 835438032Speter Include all "normal" variations on hostname in $=w. For example, 835538032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 835638032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 835738032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 835838032Speter the queue. 835938032Speter Reset SmtpPhase global on initial connection creation so that 836038032Speter messages don't come out with stale information. 836138032Speter Pass an "ext" argument to lockfile so that error/log messages 836238032Speter will properly reflect the true filename being locked. 836338032Speter Put all [...] address forms into $=w -- this eliminates the need 836438032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 836538032Speter Myers of CMU. 836638032Speter Fix a bug that can cause qf files to be left around even after 836738032Speter an SMTP RSET command. Problem and fix from Michael 836838032Speter Corrigan. 836943730Speter Don't send a PostmasterCopy to errors when the Precedence: is 837038032Speter negative. Error reports still go to the envelope 837138032Speter sender address. 837238032Speter Add LA_SHORT for load averages. 837338032Speter Lock sendmail.st file when posting statistics. 837438032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 837538032Speter set the size of the TCP send and receive buffers; if you 837638032Speter run over a slow slip line you may need to set these down 837738032Speter (although it would be better to fix the SLIP implementation 837838032Speter so that it's not necessary to recompile every program 837938032Speter that does bulk data transfer). 838038032Speter Allow null defaults on $( ... $) lookups. Problem reported by 838138032Speter Amir Plivatsky. 838238032Speter Diagnose crufty S and V config lines. This resulted from an 838338032Speter observation that some people were using the SITE macro 838438032Speter without the SITECONFIG macro first, which was causing 838538032Speter bogus config files that were not caught. 838638032Speter Fix makemap -f flag to turn off case folding (it was turning it 838738032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 838838032Speter Fix a problem that caused multiple error messages to be sent if 838938032Speter you used "sendmail -t -oem -odb", your system uses fcntl 839038032Speter locking, and one of the recipient addresses is unknown. 839138032Speter Reset uid earlier in include() so that recursive .forwards or 839238032Speter :include:s don't use the wrong uid. 839338032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 839438032Speter called, the code to recover the descriptor was broken. 839538032Speter This sometimes (only sometimes) caused problems with the 839638032Speter alias file. Fix from Motonori Nakamura. 839738032Speter Fix a problem that caused aliaswait to go into infinite recursion 839838032Speter if the @:@ metasymbol wasn't found in the alias file. 839938032Speter Improve error message on newaliases if database files cannot be 840038032Speter opened or if running with no database format defined. 840138032Speter Do a better estimation of the size of error messages when NoReturn 840238032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 840338032Speter Fix a problem causing the "c" option (don't connect to expensive 840438032Speter mailers) to be ignored in SMTP. Problem noted and the 840538032Speter solution suggested by Robert Elz of The University of 840638032Speter Melbourne. 840738032Speter Improve connection caching algorithm by passing "[host]" to 840838032Speter hostsignature, which strips the square brackets and 840938032Speter returns the real name. This allows mailertable entries 841038032Speter to match regular entries. 841138032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 841238032Speter feature, even if it doesn't work right. 841338032Speter Catch and log attempts to try the "wiz" command in server SMTP. 841438032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 841538032Speter Be more generous at assigning $z to the home directory -- do this 841638032Speter for programs that are specified through a .forward file. 841738032Speter Fix from Andrew Chang of Sun Microsystems. 841838032Speter Always save a fatal error message in preference to a non-fatal 841938032Speter error message so that the "subject" line of return 842038032Speter messages is the best possible. 842138032Speter CONFIG: reduce the number of quotes needed to quote configuration 842238032Speter parameters with commas: two quotes should work now, e.g., 842338032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 842438032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 842538032Speter connections (domain-ized UUCP). 842638032Speter CONFIG: fix bug in default maps (-o must be before database file 842764562Sgshapiro name). Pointed out by Christophe Wolfhugel. 842838032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 842938032Speter DNS. This would presumably be used in UUCP islands. 843038032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 843138032Speter CONFIG: log $u in Received: line. This is in technical violation 843238032Speter of the standards, since it doesn't guarantee a domain 843338032Speter on the address. 843438032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 843538032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 843638032Speter the "m" flag should you want it. Apparently some Solaris 2.2 843738032Speter installations can't handle multiple local recipients. 843838032Speter Problem noted by Josh Smith. 843938032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 844038032Speter CONFIG: change default version level from 4 to 5. 844138032Speter CONFIG: add FEATURE(nullclient) to create a config file that 844238032Speter forwards all mail to a hub without ever looking at the 844338032Speter addresses in any detail. 844438032Speter CONFIG: properly strip mailer: information off of relays when 844538032Speter used to change .BITNET form into %-hack form. 844638032Speter CONFIG: fix a problem that caused infinite loops if presented 844738032Speter with an address such as "!foo". 844838032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 844938032Speter the reverse "PTR" mapping is broken. There's a better 845038032Speter way to do this, but the change is fairly major and I 845138032Speter want to hold it for another release. Problem noted by 845238032Speter Bret Marquis. 845338032Speter 845464562Sgshapiro8.5/8.5 1993/07/23 845538032Speter Serious bug: if you used a command line recipient that was unknown 845638032Speter sendmail would not send a return message (it was treating 845738032Speter everything as though it had an SMTP-style client that 845838032Speter would do the return itself). Problem noted by Josh Smith. 845938032Speter Change "trymx" option in getcanonname() to ignore all MX data, 846038032Speter even during a T_ANY query. This actually didn't break 846138032Speter anything, because the only time you called getcanonname 846238032Speter with !trymx was if you already knew there were no MX 846338032Speter records, but it is somewhat cleaner. From Motonori 846438032Speter Nakamura. 846538032Speter Don't call getcanonname from getmxrr if you already know there 846638032Speter are no DNS records matching the name. 846738032Speter Fix a problem causing error messages to always include "The 846838032Speter original message was received ... from localhost". 846938032Speter The correct original host information is now included. 847038032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 847138032Speter version of "test" doesn't have the -x flag). Change it 847238032Speter to use -f instead. From John Myers. 847338032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 847438032Speter esmtp -- it should be smtp. 847538032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 847638032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 847738032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 847838032Speter this cleans up the configs somewhat. This fixes a serious 847938032Speter problem that caused route-addrs to get mistaken as relays, 848038032Speter pointed out by John Myers. WARNING: this also causes 848138032Speter the default on SMART_HOST to change from "suucp" to 848238032Speter "relay" if you have MAILER(smtp) specified. 848338032Speter 848464562Sgshapiro8.4/8.4 1993/07/22 848538032Speter Add option `w'. If you receive a message that comes to you because 848638032Speter you are the best (lowest preference) target of an MX, and 848738032Speter you haven't explicitly recognized the source MX host in 848838032Speter your .cf file, this option will cause you to try the target 848938032Speter host directly (as if there were no MX for it at all). If 849038032Speter `w' is not set, this case is a configuration error. 849138032Speter Beware: if `w' is set, senders may get bogus errors like 849238032Speter "message timed out" or "host unknown" for problems that 849338032Speter are really configuration errors. This option is 849438032Speter disrecommended, provided only for compatibility with 849538032Speter UIUC sendmail. 849638032Speter Fix a problem that caused the incoming socket to be left open 849738032Speter when sendmail forks after the DATA command. This caused 849838032Speter calling systems to wait in FIN_WAIT_2 state until the 849938032Speter entire list was processed and the child closed -- a 850038032Speter potentially prodigious amount of time. Problem noted 850138032Speter by Neil Rickert. 850238032Speter Fix problem (created in 6.64) that caused mail sent to multiple 850338032Speter addresses, one of which was a bad address, to completely 850438032Speter suppress the sending of the message. This changes 850538032Speter handling of EF_FATALERRS somewhat, and adds an 850638032Speter EF_GLOBALERRS flag. This also fixes a potential problem 850738032Speter with duplicate error messages if there is a syntax error 850838032Speter in the header of a message that isn't noticed until late 850938032Speter in processing. Original problem pointed out by Josh Smith 851038032Speter of Harvey Mudd College. This release includes quite a bit 851138032Speter of dickering with error handling (see below). 851238032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 851338032Speter will only hurt already-broken software and should help 851438032Speter humans. 851538032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 851638032Speter compiled in. It would never read the alias file. 851738032Speter Repair unbalanced `)' and `>' (the "open" versions are already 851838032Speter repaired). 851938032Speter Logging of "done" in dropenvelope() was incorrect: it would 852038032Speter log this even when the queue file still existed. Change 852138032Speter this to only log "done" (at log level 11) when the 852238032Speter queue file is actually removed. From John Myers. 852338032Speter Log "lost connection" in server SMTP at log level 20 if there 852438032Speter is no pending transaction. Some senders just close the 852538032Speter connection rather than sending QUIT. 852638032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 852738032Speter domains that do not have MX records -- this would cause 852838032Speter the subsequent host name lookup to fail. The problem 852938032Speter only occurred if you had FEATURE(nocanonify) set. 853038032Speter Problem noted by Rick McCarty of Texas Instruments. 853138032Speter Fix invocation of setvbuf when passed a -X flag -- I had 853238032Speter unwittingly used an ANSI C extension, and this caused 853338032Speter core dumps on some machines. 853438032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 853538032Speter Previously it just gave an empty send queue, which 853638032Speter then gave either "Need RCPT (recipient)" at the DATA 853738032Speter (confusing, since you had given an RCPT command which 853838032Speter returned 250) or just dropped the email, depending on 853938032Speter whether you were running VERBose mode. Now it usually 854038032Speter diagnoses this case as "aliasing/forwarding loop broken". 854138032Speter Unfortunately, it still doesn't adequately diagnose 854238032Speter some true error conditions. 854338032Speter Add internal concept of "warning messages" using 6xx codes. 854438032Speter These are not reported only to Postmaster. Unbalanced 854538032Speter parens, brackets, and quotes are printed as 653 codes. 854638032Speter They are always mapped to 5xx codes before use in SMTP. 854738032Speter Clean up error messages to tell both the actual address that 854838032Speter failed and the alias they arose from. This makes it 854938032Speter somewhat easier to diagnose problems. Difficulty noted 855038032Speter by Motonori Nakamura. 855138032Speter Fix a problem that inappropriately added a ctladdr to addresses 855238032Speter that shouldn't have had one during a queue run. This 855338032Speter caused error messages to be handled differently during 855438032Speter a queue run than a direct run. 855538032Speter Don't print the qf name and line number if you get errors during 855638032Speter the direct run of the queue from srvrsmtp -- this was 855738032Speter just extra stuff for users to crawl through. 855838032Speter Put command line flags on second line of pid file so you can 855938032Speter auto-restart the daemon with all appropriate arguments. 856038032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 856138032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 856238032Speter restart it. 856338032Speter Remove the ``setuid(getuid())'' in main -- this caused the 856438032Speter IDENT daemon to screw up. This required that I change 856538032Speter HASSETEUID to HASSETREUID and complicate the mode 856638032Speter changing somewhat because both Ultrix and SunOS seem 856738032Speter to have a bug causing seteuid() to set the saved uid 856838032Speter as well as the effective. The program test/t_setreuid.c 856938032Speter will test to see if your implementation of setreuid(2) 857038032Speter is appropriately functional. 857138032Speter The FallBackMX (option V) handling failed to properly identify 857238032Speter fallback to yourself -- most of the code was there, 857338032Speter but it wasn't being enabled. Problem noted by Murray 857438032Speter Kucherawy of the University of Waterloo. 857538032Speter Change :include: open timeout from ETIMEDOUT to an internal 857638032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 857738032Speter with CurHostName" in error messages, which can be 857838032Speter confusing. Reported by Jonathan Kamens of OpenVision 857938032Speter Technologies. 858038032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 858138032Speter process group id. The original fix was to get around 858238032Speter some problems with recalcitrant MUAs, but it breaks 858338032Speter any call from a shell that creates a process group id 858438032Speter different from the process id. I could try to fix 858538032Speter this by diddling the tty owner (using tcsetpgrp or 858638032Speter equivalent) but this is too likely to break other 858738032Speter things. 858838032Speter Portability changes: 858938032Speter Support -M as equivalent to -oM on Ultrix -- apparently 859038032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 859138032Speter instead of using standard flags. Oh joy. This 859243730Speter behavior reported by Jon Giltner of University 859338032Speter of Colorado. 859438032Speter SGI IRIX -- this includes several changes that should 859538032Speter help other strict ANSI compilers. 859638032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 859738032Speter Corporation. 859838032Speter Solaris running the Sun C compiler (which despite the 859938032Speter documentation apparently doesn't define 860038032Speter __STDC__ by default). 860138032Speter ConvexOS from Eric Schnoebelen of Convex. 860238032Speter Sony NEWS workstations and Omron LUNA workstations from 860338032Speter Motonori Nakamura. 860438032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 860538032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 860638032Speter several people have made a good argument that this 860738032Speter creates more problems than it solves (although this 860838032Speter may prove painful in the short run). 860938032Speter CONFIG: generalize all the relays to accept a "mailer:host" 861038032Speter format. 861138032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 861238032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 861338032Speter addresses are also passed through this ruleset. 861438032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 861538032Speter internet-style addresses would "fall off the end" of 861638032Speter ruleset zero and be interpreted as local -- however, 861738032Speter the angle brackets confused the recursive call. 861838032Speter These are now diagnosed as "Unrecognized host name". 861938032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 862038032Speter ifdef(`_MAILER_USENET_') instead of 862138032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 862238032Speter of SINTEF RUNIT, Oslo. 862338032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 862438032Speter early in ruleset 0; this allows .mc authors to bypass 862538032Speter things like the "short circuit" code for local addresses. 862638032Speter Prompted by a comment by Bill Wisner of The Well. 862738032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 862838032Speter esmtp) to send SMTP mail. This allows you to default 862938032Speter to esmtp but use a mailertable or other override to 863038032Speter deal with broken servers. This logic was pointed out 863138032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 863238032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 863338032Speter environments. Ugly as sin. 863438032Speter 863564562Sgshapiro8.3/8.3 1993/07/13 863638032Speter Fix setuid problems introduced in 8.2 that caused messages 863738032Speter like "Cannot create qfXXXXXX: Invalid argument" 863838032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 863938032Speter involved a new compile flag "HASSETEUID" that takes 864038032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 864138032Speter that the POSIX interface is broken enough to break 864238032Speter some systems badly. This includes some fixes for 864338032Speter HP-UX. Also fixes problems where the real uid is 864438032Speter not reset properly on startup (from Neil Rickert). 864538032Speter Fix a problem that caused timed out messages to not report the 864638032Speter addresses that timed out. Error messages are also more 864738032Speter "user friendly". 864838032Speter Drop required bandwidth on connections from 64 bytes/sec to 864938032Speter 16 bytes/sec. 865038032Speter Further Solaris portability changes -- doesn't require the BSD 865138032Speter compatibility library. This also adds a new 865238032Speter "HASGETDTABLESIZE" compile flag which can be used if 865338032Speter you want to use getdtablesize(2) instead of sysconf(2). 865438032Speter These are loosely based on changes from David Meyer at 865538032Speter University of Oregon. This now seems to work, at least 865638032Speter for quick test cases. 865738032Speter Fix a problem that can cause duplicate error messages to be 865838032Speter sent if you are in SMTP, you send to multiple addresses, 865938032Speter and at least one of those addresses is good and points 866038032Speter to an account that has a .forward file (whew!). 866138032Speter Fix a problem causing messages to be discarded if checkcompat() 866238032Speter returned EX_TEMPFAIL (because it didn't properly mark 866338032Speter the "to" address). Problem noted by John Myers. 866438032Speter Fix dfopen to return NULL if the open failed; I was depending 866538032Speter on fdopen(-1) returning NULL, which isn't the case. This 866638032Speter isn't serious, but does result in weird error diagnoses. 866738032Speter From Michael Corrigan. 866838032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 866938032Speter messages sent through UUCP-family mailers. Suggested 867038032Speter by Bill Wisner of The Well. 867138032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 867238032Speter include a "uucp-dom" mailer that uses domain-style 867338032Speter addressing. Suggested by Bill Wisner. 867438032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 867538032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 867638032Speter Christophe Wolfhugel. 867738032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 867838032Speter 867964562Sgshapiro8.2/8.2 1993/07/11 868038032Speter Don't drop out on config file parse errors in -bt mode. 868138032Speter On older configuration files, assume option "l" (use Errors-To 868238032Speter header) for back compatibility. NOTE: this DOES NOT 868338032Speter imply an endorsement of the Errors-To: header in any way. 868438032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 868538032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 868638032Speter SMTP server to give an error on this command, and 868738032Speter logging it in the transcript can be confusing. Fix 868838032Speter from Bill Wisner. 868938032Speter IRIX compatibility changes provided by Dan Rich 869038032Speter <drich@sandman.lerc.nasa.gov>. 869138032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 869238032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 869338032Speter <juo@klinzhai.rutgers.edu> 869438032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 869538032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 869638032Speter match the other flags in that file. 869738032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 869838032Speter Save h_errno in mci struct and improve error message display. 869938032Speter Changes from Eric Wassenaar. 870038032Speter Open /dev/null for the transcript if the create of the xf file 870138032Speter failed; this avoids at least one possible null pointer 870238032Speter reference in very weird cases. From Eric Wassenaar. 870338032Speter Clean up statistics gathering; it was over-reporting because of 870438032Speter forks. From Eric Wassenaar. 870538032Speter Fix problem that causes old Return-Path: line to override new 870638032Speter Return-Path: line (conf.c needs H_FORCE to avoid 870738032Speter re-using old value). From Motonori Nakamura. 870838032Speter Fix broken -m flag in K definition -- even if -m (match only) 870938032Speter was specified, it would still replace the key with the 871038032Speter value. Noted by Rick McCarty of Texas Instruments. 871138032Speter If the name server timed out over several days, no "timed out" 871238032Speter message would ever be sent back. The timeout code 871338032Speter has been moved from markfailure() to dropenvelope() 871438032Speter so that all such failures should be diagnosed. Pointed 871538032Speter out by Christophe Wolfhugel and others. 871638032Speter Relax safefile() constraints: directories in an include or 871738032Speter forward path must be readable by self if the controlling 871838032Speter user owns the entry, readable by all otherwise (e.g., 871938032Speter when reading your .forward file, you have to own and 872038032Speter have X permission in it; everyone needs X permission in 872138032Speter the root and directories leading up to your home); 872238032Speter include files must be readable by anyone, but need not 872338032Speter be owned by you. 872438032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 872538032Speter reading a .forward file; this gets around some problems 872638032Speter on NFS mounts if root permission is not exported and 872738032Speter the user's home directory isn't x'able. 872838032Speter Additional NeXT portability enhancements from Axel Zinser. 872938032Speter Additional HP-UX portability enhancements from Brian Bullen. 873038032Speter Add a timeout around SMTP message writes; this assumes you can 873138032Speter get throughput of at least 64 bytes/second. Note that 873238032Speter this does not impact the "datafinal" default, which 873338032Speter is separate; this is just intended to work around 873438032Speter network clogs that will occur before the final dot 873538032Speter is sent. From Eric Wassenaar. 873638032Speter Change map code to set the "include null" flag adaptively -- 873738032Speter it initially tries both, but if it finds anything 873838032Speter matching without a null it never tries again with a 873938032Speter null and vice versa. If -N is specified, it never 874038032Speter tries without the null and creates new maps with a 874138032Speter null byte. If -O is specified, it never tries with 874238032Speter the null (for efficiency). If -N and -O are specified, 874338032Speter you get -NO (get it?) lookup at all, so this would 874438032Speter be a bad idea. If you don't specify either -N or -O, 874538032Speter it adapts. 874638032Speter Fix recognition of "same from address" so that MH submissions 874738032Speter will insert the appropriate full name information; 874838032Speter this used to work and got broken somewhere along the 874938032Speter way. 875038032Speter Some changes to eliminate some unnecessary SYSERRs in the 875138032Speter log. For example, if you lost a connection, don't 875238032Speter bother reporting that fact on the connection you lost. 875338032Speter Add some "extended debugging" flags to try to track down 875438032Speter why we get occasional problems with file descriptor 875538032Speter one being closed when execing a mailer; it seems to 875638032Speter only happen when there has been another error in the 875738032Speter same transaction. This requires XDEBUG, defined 875838032Speter by default in conf.h. 875938032Speter Add "-X filename" command line flag, which logs both sides of 876038032Speter all SMTP transactions. This is intended ONLY for 876138032Speter debugging bad implementations of other mailers; start 876238032Speter it up, send a message from a mailer that is failing, 876338032Speter and then kill it off and examine the indicated log. 876438032Speter This output is not intended to be particularly human 876538032Speter readable. This also adds the HASSETVBUF compile 876638032Speter flag, defaulted on if your compiler defines __STDC__. 876738032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 876838032Speter have a local net that should get direct connects, you 876938032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 877038032Speter See cf/README for an example. 877138032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 877238032Speter sites that don't use the -d flag. 877338032Speter CONFIG: hide recipient addresses as well as sender addresses 877438032Speter behind $M if FEATURE(allmasquerade) is specified; this 877538032Speter has been requested by several people, but can break 877638032Speter local aliases. For example, if you mail to "localalias" 877738032Speter this will be rewritten as "localalias@masqueradehost"; 877838032Speter although initial delivery will work, replies will be 877938032Speter broken. Use it sparingly. 878038032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 878138032Speter to qualified domains in headers. I believe this is 878238032Speter largely equivalent to the IDA feature of the same name. 878338032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 878438032Speter to override the "system name" as your UUCP name -- 878538032Speter in particular, to use domain-ized UUCP names. From 878638032Speter Bill Wisner of The Well. 878738032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 878838032Speter first. This is currently unused in the config files, 878938032Speter but could be used in a mailertable entry. 879038032Speter 879164562Sgshapiro8.1C/8.1B 1993/06/27 879238032Speter Serious security bug fix: it was possible to read any file on 879338032Speter the system, regardless of ownership and permissions. 879438032Speter If a subroutine returns a fully qualified address, return it 879538032Speter immediately instead of feeding it back into rewriting. 879638032Speter This fixes a problem with mailertable lookups. 879738032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 879838032Speter 879964562Sgshapiro8.1B/8.1A 1993/06/12 880038032Speter Serious bug fix: pattern matching backup algorithm stepped by 880138032Speter two tokens in classes instead of one.
