This could cause session 12110560Sgshapiro oriented restrictions, e.g., STARTTLS requirements, 13110560Sgshapiro to erroneously allow a connection. Problem noted 14110560Sgshapiro by Tim Maletic of Priority Health. 15110560Sgshapiro Do not lookup MX records when sorting the MSP queue. The MSP 16110560Sgshapiro only needs to relay all mail to the MTA. Problem found 17110560Sgshapiro by Gary Mills of the University of Manitoba. 18110560Sgshapiro Do not restrict the length of connection information to 100 19110560Sgshapiro characters in some logging statements. Problem noted by 20110560Sgshapiro Erik Parker. 21110560Sgshapiro When converting an enhanced status code to an exit status, use 22110560Sgshapiro EX_CONFIG if the first digit is not 2, 4, or 5 or if *.1.5 23110560Sgshapiro is used. 24110560Sgshapiro Reset macro $x when receiving another MAIL command. Problem 25110560Sgshapiro noted by Vlado Potisk of Wigro s.r.o. 26110560Sgshapiro Don't bother setting the permissions on the build area statistics 27110560Sgshapiro file, the proper permissions will be put on the file at 28110560Sgshapiro install time.

Problem noted by Neil 56110560Sgshapiro Rickert of Northern Illinois University. 57110560Sgshapiro Avoid problems with QueueSortOrder=random due to problems with 58110560Sgshapiro qsort() on Solaris (and maybe some other operating systems). 59110560Sgshapiro Problem noted by Stephan Schulz of Gruner+Jahr.. 60110560Sgshapiro If -f "" is specified, set the sender address to "<>". Problem 61110560Sgshapiro noted by Matthias Andree. 62110560Sgshapiro Fix formatting problem of footnotes for plain text output on some 63110560Sgshapiro versions of tmac. Patch from Per Hedeland of Ericsson. 64110560Sgshapiro Portability: 65110560Sgshapiro Berkeley DB 4.1 support (requires at least 4.1.25). 66110560Sgshapiro Some getopt(3) implementations in GNU/Linux are broken 67110560Sgshapiro and pass a NULL pointer to an option which requires 68110560Sgshapiro an argument, hence the builtin version of 69110560Sgshapiro sendmail is used instead. This can be overridden 70110560Sgshapiro by using -DSM_CONF_GETOPT=0. Problem noted by 71110560Sgshapiro Vlado Potisk of Wigro s.r.o. 72110560Sgshapiro Support for nph-1.2.0 from Mark D. Roth of the University 73110560Sgshapiro of Illinois at Urbana-Champaign. 74110560Sgshapiro Support for FreeBSD 5.0's MAC labeling from Robert Watson 75110560Sgshapiro of the TrustedBSD Project. 76110560Sgshapiro Support for reading the number of processors on an IRIX 77110560Sgshapiro system from Michel Bourget of SGI. 78110560Sgshapiro Support for UnixWare 7.1 based on input from Larry Rosenman. 79110560Sgshapiro Interix support from Nedelcho Stanev of Atlantic Sky 80110560Sgshapiro Corporation. 81110560Sgshapiro Update Mac OS X/Darwin portability from Wilfredo Sanchez. 82110560Sgshapiro CONFIG: Enforce tls_client restrictions even if delay_checks 83110560Sgshapiro is used. Problem noted by Malte Starostik. 84110560Sgshapiro CONFIG: Deal with an empty hostname created via bogus 85110560Sgshapiro DNS entries to get around access restrictions. 86110560Sgshapiro Problem noted by Kai Schlichting. 87110560Sgshapiro CONFIG: Use FEATURE(`msp', `[127.0.0.1]') in submit.mc by default 88110560Sgshapiro to avoid problems with hostname resolution for localhost 89110560Sgshapiro which on many systems does not resolve to 127.0.0.1 (or 90110560Sgshapiro ::1 for IPv6). If you do not use IPv4 but only IPv6 then 91110560Sgshapiro you need to change submit.mc accordingly, see the comment 92110560Sgshapiro in the file itself. 93110560Sgshapiro CONFIG: Set confDONT_INIT_GROUPS to True in submit.mc to avoid 94110560Sgshapiro error messages from initgroups(3) on AIX 4.3 when sending 95110560Sgshapiro mail to non-existing users. Problem noted by Mark Roth of 96110560Sgshapiro the University of Illinois at Urbana-Champaign. 97110560Sgshapiro CONFIG: Allow local_procmail to override local_lmtp settings. 98110560Sgshapiro CONFIG: Always allow connections from 127.0.0.1 or IPv6:::1 to 99110560Sgshapiro relay. 100110560Sgshapiro CONTRIB: cidrexpand: Deal with the prefix tags that may be included 101110560Sgshapiro in access_db. 102110560Sgshapiro CONTRIB: New version of doublebounce.pl contributed by Leo Bicknell. 103110560Sgshapiro LIBMILTER: On Solaris libmilter may get into an endless loop if 104110560Sgshapiro an error in the communication from/to the MTA occurs. 105110560Sgshapiro Patch from Gurusamy Sarathy of Active State. 106110560Sgshapiro LIBMILTER: Ignore EINTR from sigwait(3) which may happen on Tru64. 107110560Sgshapiro Patch from from Jose Marcio Martins da Cruz of Ecole 108110560Sgshapiro Nationale Superieure des Mines de Paris. 109110560Sgshapiro MAIL.LOCAL: Fix a truncation race condition if the close() on 110110560Sgshapiro the mailbox fails. Problem noted by Tomoko Fukuzawa of 111110560Sgshapiro Sun Microsystems. 112110560Sgshapiro MAIL.LOCAL: Fix a potential file descriptor leak if mkstemp(3) 113110560Sgshapiro fails. Patch from John Beck of Sun Microsystems. 114110560Sgshapiro SMRSH: SECURITY: Only allow regular files or symbolic links to be 115110560Sgshapiro used for a command. Problem noted by David Endler of 116110560Sgshapiro iDEFENSE, Inc. 117110560Sgshapiro New Files: 118110560Sgshapiro devtools/OS/Interix 119110560Sgshapiro include/sm/bdb.h 120110560Sgshapiro 121102528Sgshapiro8.12.6/8.12.6 2002/08/26 122102528Sgshapiro Do not add the FallbackMXhost (or its MX records) to the list 123102528Sgshapiro returned by the bestmx map when -z is used as option. 124102528Sgshapiro Otherwise sendmail may act as an open relay if FallbackMXhost 125102528Sgshapiro and FEATURE(`relay_based_on_MX') are used together. 126102528Sgshapiro Problem noted by Alexander Ignatyev. 127102528Sgshapiro Properly split owner- mailing list messages when SuperSafe is set 128102528Sgshapiro to interactive. Problem noted by Todd C. Miller of 129102528Sgshapiro Courtesan Consulting. 130102528Sgshapiro Make sure that an envelope is queued in the selected queue group 131102528Sgshapiro even if some recipients are deleted or invalid. Problem 132102528Sgshapiro found by Chris Adams of HiWAAY Informations Services. 133102528Sgshapiro Do not send a bounce message if a message is completely collected 134102528Sgshapiro from the SMTP client. Problem noted by Kari Hurtta of the 135102528Sgshapiro Finnish Meteorological Institute. 136102528Sgshapiro Provide an 'install-submit-st' target for sendmail/Makefile to 137102528Sgshapiro install the MSP statistics file using the file named in the 138102528Sgshapiro confMSP_STFILE devtools variable. Requested by Jeff 139102528Sgshapiro Earickson of Colby College. 140102528Sgshapiro Queue up mail with a temporary error if setusercontext() fails 141102528Sgshapiro during a delivery attempt. Patch from Todd C. Miller of 142102528Sgshapiro Courtesan Consulting. 143102528Sgshapiro Fix handling of base64 encoded client authentication data for 144102528Sgshapiro SMTP AUTH. Patch from Elena Slobodnik of life medien GmbH. 145102528Sgshapiro Set the OpenLDAP option LDAP_OPT_RESTART so the client libraries 146102528Sgshapiro restart interrupted system calls. Problem noted by Luiz 147102528Sgshapiro Henrique Duma of BSIOne. 148102528Sgshapiro Prevent a segmentation fault if a program passed a NULL envp using 149102528Sgshapiro execve(). 150102528Sgshapiro Document a problem with the counting of queue runners that may 151102528Sgshapiro cause delays if MaxQueueChildren is set too low. Problem 152102528Sgshapiro noted by Ian Duplisse of Cable Television Laboratories, Inc. 153102528Sgshapiro If discarding a message based on a recipient, don't try to look up 154102528Sgshapiro the recipient in the mailbox database if F=w is set. This 155102528Sgshapiro allows users to discard bogus recipients when dealing with 156102528Sgshapiro spammers without tipping them off. Problem noted by Neil 157102528Sgshapiro Rickert of Northern Illinois University. 158102528Sgshapiro If applying a header check to a header with unstructured data, 159102528Sgshapiro e.g., Subject:, then do not run syntax checks that are 160102528Sgshapiro supposed for addresses on the header content. 161102528Sgshapiro Count messages rejected/discarded via the check_data ruleset. 162102528Sgshapiro Portability: 163102528Sgshapiro Fix compilation on systems which do not allow simple 164102528Sgshapiro copying of the variable argument va_list. Based on 165102528Sgshapiro fix from Scott Walters. 166102528Sgshapiro Fix NSD map open bug. From Michel Bourget of SGI. 167102528Sgshapiro Add some additional IRIX shells to the default shell 168102528Sgshapiro list. From Michel Bourget of SGI. 169102528Sgshapiro Fix compilation issues on Mac OS X 10.2 (Darwin 6.0). 170102528Sgshapiro NETISO support has been dropped. 171102528Sgshapiro CONFIG: There was a seemingly minor change in 8.12.4 with respect 172102528Sgshapiro to handling entries of IP nets/addresses with RHS REJECT. 173102528Sgshapiro These would be rejected in check_rcpt instead of only 174102528Sgshapiro being activated in check_relay. This change has been made to 175102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 176102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 177102528Sgshapiro record for ..." if delay_checks is enabled. However, this 178102528Sgshapiro modification causes a change of behavior if an IP net/address 179102528Sgshapiro is listed in the access map with REJECT and a host/domain 180102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 181102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 182102528Sgshapiro change was made on request of Neil Rickert of Northern 183102528Sgshapiro Illinois University, the side effect has been found by 184102528Sgshapiro Stefaan Van Hoornick. 185102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 186102528Sgshapiro using the local hostname ($j) or domains in class {P}. 187102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 188102528Sgshapiro University. 189102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 190102528Sgshapiro Fix from Andrzej Filip. 191102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 192102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 193102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 194102528Sgshapiro NULL pointer. Problem noted by Andrey J. Melnikoff. 195102528Sgshapiro LIBMILTER: Protect against more interrupted select() calls. Based 196102528Sgshapiro on patch from Jose Marcio Martins da Cruz of Ecole Nationale 197102528Sgshapiro Superieure des Mines de Paris. 198102528Sgshapiro New Files: 199102528Sgshapiro contrib/etrn.0 200102528Sgshapiro 20198841Sgshapiro8.12.5/8.12.5 2002/06/25 20298841Sgshapiro SECURITY: The DNS map can cause a buffer overflow if the user 20398841Sgshapiro specifies a dns map using TXT records in the configuration 20498841Sgshapiro file and a rogue DNS server is queried. None of the 20598841Sgshapiro sendmail supplied configuration files use this option hence 20698841Sgshapiro they are not vulnerable. Problem noted independently by 20798841Sgshapiro Joost Pol of PINE Internet and Anton Rang of Sun Microsystems. 20898841Sgshapiro Unprintable characters in responses from DNS servers for the DNS 20998841Sgshapiro map type are changed to 'X' to avoid potential problems 21098841Sgshapiro with rogue DNS servers. 21198841Sgshapiro Require a suboption when setting the Milter option. Problem noted 21298841Sgshapiro by Bryan Costales. 21398841Sgshapiro Do not silently overwrite command line settings for 21498841Sgshapiro DirectSubmissionModifiers. Problem noted by Bryan 21598841Sgshapiro Costales. 21698841Sgshapiro Prevent a segmentation fault when clearing the event list by 21798841Sgshapiro turning off alarms before checking if event list is 21898841Sgshapiro empty. Problem noted by Allan E Johannesen of Worcester 21998841Sgshapiro Polytechnic Institute. 22098841Sgshapiro Close a potential race condition in transitioning a memory buffered 22198841Sgshapiro file onto disk. From Janani Devarajan of Sun Microsystems. 22298841Sgshapiro Portability: 22398841Sgshapiro Include paths.h on Linux systems running glibc 2.0 or later 22498841Sgshapiro to get the definition for _PATH_SENDMAIL, used by 22598841Sgshapiro rmail and vacation. Problem noted by Kevin 22698841Sgshapiro A. McGrail of Peregrine Hardware. 22798841Sgshapiro NOTE: Linux appears to have broken flock() again. Unless 22898841Sgshapiro the bug is fixed before sendmail 8.13 is shipped, 22998841Sgshapiro 8.13 will change the default locking method to 23098841Sgshapiro fcntl() for Linux kernel 2.4 and later. You may 23198841Sgshapiro want to do this in 8.12 by compiling with 23298841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 23398841Sgshapiro related programs to match locking techniques. 23498841Sgshapiro 23598121Sgshapiro8.12.4/8.12.4 2002/06/03 23698121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 23798121Sgshapiro can leave systems open to a local denial of service 23898121Sgshapiro attack. Be sure to read the "FILE AND MAP PERMISSIONS" 23998121Sgshapiro section of the top level README for more information. 24098121Sgshapiro Problem noted by lumpy. 24198121Sgshapiro Use TempFileMode (defaults to 0600) for the permissions of PidFile 24298121Sgshapiro instead of 0644. 24398121Sgshapiro Change the default file permissions for new alias database files 24498121Sgshapiro from 0644 to 0640. This can be overridden at compile time 24598121Sgshapiro by setting the DBMMODE macro. 24698121Sgshapiro Fix a potential core dump problem if the environment variable 24798121Sgshapiro NAME is set. Problem noted by Beth A. Chaney of 24898121Sgshapiro Purdue University. 24998121Sgshapiro Expand macros before passing them to libmilter.

Problem noted by Gisle Aas 25498121Sgshapiro of Active State. 25598121Sgshapiro Change SMTP reply code for AUTH failure from 500 to 535 and the 25698121Sgshapiro initial zero-length response to "=" per RFC 2554. Patches 25798121Sgshapiro from Kenneth Murchison of Oceana Matrix Ltd. 25898121Sgshapiro Do not try to fix broken message/rfc822 MIME attachments by 25998121Sgshapiro inserting a MIME-Version: header when MaxMimeHeaderLength 26098121Sgshapiro is set and no 8 to 7 bit conversion is needed. Based on 26198121Sgshapiro patch from Rehor Petr of ICZ (Czech Republic). 26298121Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" if the connection 26398121Sgshapiro is rejected anyway. Noted by Chris Loelke. 26498121Sgshapiro Mention the submission mail queue in the mailq man page. Requested 26598121Sgshapiro by Bill Fenner of AT&T. 26698121Sgshapiro Set ${msg_size} macro when reading a message from the command line 26798121Sgshapiro or the queue. 26898121Sgshapiro Detach from shared memory before dropping privileges back to 26998121Sgshapiro user who started sendmail. 27098121Sgshapiro If AllowBogusHELO is set to false (default) then also complain if 27198121Sgshapiro the argument to HELO/EHLO contains white space. Suggested 27298121Sgshapiro by Seva Gluschenko of Cronyx Plus. 27398121Sgshapiro Allow symbolicly linked forward files in writable directory paths 27498121Sgshapiro if both ForwardFileInUnsafeDirPath and 27598121Sgshapiro LinkedForwardFileInWritableDir DontBlameSendmail options 27698121Sgshapiro are set. Problem noted by Werner Spirk of 27798121Sgshapiro Leibniz-Rechenzentrum Munich. 27898121Sgshapiro Portability: 27998121Sgshapiro Operating systems that lack the ftruncate() call will not 28098121Sgshapiro be able to use Milter's body replacement feature. 28198121Sgshapiro This only affects Altos, Maxion, and MPE/iX. 28298121Sgshapiro Digital UNIX 5.0 has changed flock() semantics to be 28398121Sgshapiro non-compliant. Problem noted by Martin Mokrejs of 28498121Sgshapiro Charles University in Prague. 28598121Sgshapiro The sparc64 port of FreeBSD 5.0 now supports shared 28698121Sgshapiro memory. 28798121Sgshapiro CONFIG: FEATURE(`preserve_luser_host') needs the macro map. 28898121Sgshapiro Problem noted by Andrzej Filip. 28998121Sgshapiro CONFIG: Using 'local:' as a mailertable value with 29098121Sgshapiro FEATURE(`preserve_luser_host') and LUSER_RELAY caused mail 29198121Sgshapiro to be misaddressed. Problem noted by Andrzej Filip. 29298121Sgshapiro CONFIG: Provide a workaround for DNS based rejection lists that 29398121Sgshapiro fail for AAAA queries. Problem noted by Chris Boyd. 29498121Sgshapiro CONFIG: Accept the machine's hostname as resolvable when checking 29598121Sgshapiro the sender address. This allows locally submitted mail to 29698121Sgshapiro be accepted if the machine isn't connected to a nameserver 29798121Sgshapiro and doesn't have an /etc/hosts entry for itself. Problem 29898121Sgshapiro noted by Robert Watson of the TrustedBSD Project. 29998121Sgshapiro CONFIG: Use deferred expansion for checking the ${deliveryMode} 30098121Sgshapiro macro in case the SMTP VERB command is used.

Problem 32498121Sgshapiro noted by Bryan Costales. 32598121Sgshapiro New Files: 32698121Sgshapiro cf/mailer/cyrusv2.m4 32798121Sgshapiro 32894334Sgshapiro8.12.3/8.12.3 2002/04/05 32994334Sgshapiro NOTICE: In general queue files should not be moved if queue groups 33094334Sgshapiro are used. In previous versions this could cause mail 33194334Sgshapiro not to be delivered if a queue file is repeatedly moved 33294334Sgshapiro by an external process whenever sendmail moved it back 33394334Sgshapiro into the right place. Some precautions have been taken 33494334Sgshapiro to avoid moving queue files if not really necessary. 33594334Sgshapiro sendmail may use links to refer to queue files and it 33694334Sgshapiro may store the path of data files in queue files. Hence 33794334Sgshapiro queue files should not be moved unless those internals 33894334Sgshapiro are understood and the integrity of the files is not 33994334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 34094334Sgshapiro University. 34194334Sgshapiro If an error mail is created, and the mail is split across different 34294334Sgshapiro queue directories, and SuperSafe is off, then write the mail 34394334Sgshapiro to disk before splitting it, otherwise an assertion is 34494334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 34594334Sgshapiro of INTERMETA. 34694334Sgshapiro Fix possible race condition that could cause sendmail to forget 34794334Sgshapiro running queues. Problem noted by Jeff Wasilko of smoe.org. 34894334Sgshapiro Handle bogus qf files better without triggering assertions. 34994334Sgshapiro Problem noted by Guy Feltin. 35094334Sgshapiro Protect against interrupted select() call when enforcing Milter 35194334Sgshapiro read and write timeouts. Patch from Gurusamy Sarathy of 35294334Sgshapiro ActiveState. 35394334Sgshapiro Matching queue IDs with -qI should be case sensitive. Problem 35494334Sgshapiro noted by Anne Bennett of Concordia University. 35594334Sgshapiro If privileges have been dropped, don't try to change group ID to 35694334Sgshapiro the RunAsUser group. Problem noted by Neil Rickert of 35794334Sgshapiro Northern Illinois University. 35894334Sgshapiro Fix SafeFileEnvironment path munging when the specified path 35994334Sgshapiro contains a trailing slash. Based on patch from Dirk Meyer 36094334Sgshapiro of Dinoex. 36194334Sgshapiro Do not limit sendmail command line length to SM_ARG_MAX (usually 36294334Sgshapiro 4096). Problem noted by Allan E Johannesen of Worcester 36394334Sgshapiro Polytechnic Institute. 36494334Sgshapiro Clear full name of sender for each new envelope to avoid bogus data 36594334Sgshapiro if several mails are sent in one session and some of them 36694334Sgshapiro do not have a From: header. Problem noted by Bas Haakman. 36794334Sgshapiro Change timeout check such that cached information about a connection 36894334Sgshapiro will be immediately invalid if ConnectionCacheTimeout is zero. 36994334Sgshapiro Based on patch from David Burns of Portland State University. 37094334Sgshapiro Properly count message size for mailstats during mail collection. 37194334Sgshapiro Problem noted by Werner Wiethege. 37294334Sgshapiro Log complete response from LMTP delivery agent on failure. Based on 37394334Sgshapiro patch from by Motonori Nakamura of Kyoto University. 37494334Sgshapiro Provide workaround for getopt() implementations that do not catch 37594334Sgshapiro missing arguments. 37694334Sgshapiro Fix the message size calculation if the message body is replaced by 37794334Sgshapiro a milter filter and buffered file I/O is being used. 37894334Sgshapiro Problem noted by Sergey Akhapkin of Dr.Web. 37994334Sgshapiro Do not honor SIGUSR1 requests if running with extra privileges. 38094334Sgshapiro Problem noted by Werner Wiethege. 38194334Sgshapiro Prevent a file descriptor leak on mail delivery if the initial 38294334Sgshapiro connect fails and DialDelay is set. Patch from Servaas 38394334Sgshapiro Vandenberghe of Katholieke Universiteit Leuven. 38494334Sgshapiro Properly deal with a case where sendmail is called by root running 38594334Sgshapiro a set-user-ID (non-root) program. Problem noted by Jon 38694334Sgshapiro Lusky of ISS Atlanta. 38794334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 38894334Sgshapiro directories are used and mail is sent to a mailing list 38994334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 39094334Sgshapiro of Concordia University. 39194334Sgshapiro Fix class map parsing code if optional key is specified. Problem 39294334Sgshapiro found by Mario Nigrovic. 39394334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 39494334Sgshapiro incoming messages. A leading dot is always stripped by the 39594334Sgshapiro SMTP receiver regardless of whether or not it is followed by 39694334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 39794334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 39894334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 39994334Sgshapiro Elvers. 40094334Sgshapiro Correct the statistics gathered for total number of connections. 40194334Sgshapiro Instead of being the exact same number as the total number 40294334Sgshapiro of messages (T line in mailstats) it now represents the 40394334Sgshapiro total number of TCP connections. 40494334Sgshapiro Be more explicit about syntax errors in addresses, especially 40594334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 40694334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 40794334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 40894334Sgshapiro are used. Problem noted by Suresh Ramasubramanian. 40994334Sgshapiro Prevent a race condition on child cleanup for delivery to files. 41094334Sgshapiro Problem noted by Fletcher Mattox of the University of 41194334Sgshapiro Texas. 41294334Sgshapiro Change the SMTP error code for temporary map failures from 421 41394334Sgshapiro to 451. 41494334Sgshapiro Do not assume that realloc(NULL, size) works on all OS (this was 41594334Sgshapiro only done in one place: queue group creation). Based on 41694334Sgshapiro patch by Bryan Costales. 41794334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 41894334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 41994334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 42094334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 42194334Sgshapiro errors. By doing so, the host was marked as having a 42294334Sgshapiro temporary problem and other mail destined for that host was 42394334Sgshapiro queued for the next queue run. Problem noted by Fletcher 42494334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 42594334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 42694334Sgshapiro and Neil Rickert of Northern Illinois University. 42794334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 42894334Sgshapiro which drop the connection instead of responding to the 42994334Sgshapiro command). 43094334Sgshapiro Portability: 43194334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 43298121Sgshapiro available. 43394334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 43494334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 43594334Sgshapiro settings. Patch from Elias Halldor Agustsson of 43694334Sgshapiro Skyrr. 43794334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 43894334Sgshapiro noted by John Beck. 43994334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 44094334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX. From 44194334Sgshapiro Rajesh Somasund of Hewlett-Packard. 44294334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 44394334Sgshapiro SMTP AUTH information. This feature was actually added in 44494334Sgshapiro 8.12.0 but a release note was not included. 44594334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 44694334Sgshapiro parameter is set and the LDAP lookup returns a temporary 44794334Sgshapiro error. 44894334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 44994334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 45094334Sgshapiro Krzysztof Oledzki. 45194334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 45294334Sgshapiro initialization as aliases are not needed for the MSP. 45394334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 45494334Sgshapiro is in use. Patch from Andrzej Filip. 45594334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 45694334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 45794334Sgshapiro This will only have an effect if a parameter is specified, 45894334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 45994334Sgshapiro it is embedded in square brackets. Problem noted by 46094334Sgshapiro Theo Van Dinter of Collective Technologies. 46194334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 46294334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 46394334Sgshapiro to allow for the proper time zone on systems where the 46494334Sgshapiro default results in misleading time stamps. That is, syslog 46594334Sgshapiro time stamps and Date headers on submitted mail will use the 46694334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 46794334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 46894334Sgshapiro by Neil Rickert of Northern Illinois University. 46994334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 47094334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 47194334Sgshapiro noted by John Beck. 47294334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 47394334Sgshapiro if queue groups are used. 47494334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 47594334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 47694334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 47794334Sgshapiro Suggested by Bryan Costales. 47894334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 47994334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 48094334Sgshapiro structure that is passed to xxfi_connect(). Notice: 48198121Sgshapiro this fix requires that sendmail and libmilter both have 48298121Sgshapiro this change; mixing versions may lead to wrong port 48394334Sgshapiro values depending on the endianness of the involved systems. 48494334Sgshapiro Problem noted by Gisle Aas of ActiveState. 48594334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 48694334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 48794334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 48894334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 48994334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 49094334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 49194334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 49294334Sgshapiro this to 1 if your LDAP client libraries include 49394334Sgshapiro ldap_memfree(). 49494334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 49594334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 49694334Sgshapiro SMRSH: Fix compilation problem on some operating systems. Problem 49794334Sgshapiro noted by Christian Krackowizer of schuler technodat GmbH. 49894334Sgshapiro VACATION: Allow root to operate on user vacation databases. Based 49994334Sgshapiro on patch from Greg Couch of the University of California, 50094334Sgshapiro San Francisco. 50194334Sgshapiro VACATION: Don't ignore -C option.

Problem noted 51490792Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 51590792Sgshapiro Properly record dropped connections in persistent host status. 51690792Sgshapiro Problem noted by Ulrich Windl of the Universitat 51790792Sgshapiro Regensburg. 51890792Sgshapiro Remove newlines from recipients read via sendmail -t to prevent 51990792Sgshapiro SMTP protocol errors when sending the RCPT command. 52090792Sgshapiro Problem noted by William D. Colburn of the New Mexico 52190792Sgshapiro Institute of Mining and Technology. 52290792Sgshapiro Only log milter body replacements once instead of for each body 52390792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 52490792Sgshapiro the Finnish Meteorological Institute. 52590792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 52690792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 52790792Sgshapiro of the Finnish Meteorological Institute. 52890792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 52990792Sgshapiro needs to collect children status to avoid zombie processes. 53090792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 53190792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 53290792Sgshapiro commands are issued. This makes it consistent with normal 53390792Sgshapiro SMTP connections. 53490792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 53590792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 53690792Sgshapiro and Technology. 53790792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 53890792Sgshapiro message sender if the sender had used a deprecated RFC822 53990792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 54090792Sgshapiro Meteorological Institute. 54190792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 54290792Sgshapiro parsing. Problem noted by Jorg Bielak from Coastal Web 54390792Sgshapiro Online. 54490792Sgshapiro For systems on which stat(2) does not return a value for st_blksize 54590792Sgshapiro that is the "optimal blocksize for I/O" three new compile 54690792Sgshapiro time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF, 54790792Sgshapiro and SM_IO_MAX_BUF, which define an upper limit for 54890792Sgshapiro regular files, and a lower and upper limit for other file 54990792Sgshapiro types, respectively. 55090792Sgshapiro Fix a potential deadlock if two events are supposed to occur at 55190792Sgshapiro exactly the same time.

Patch from David Powell 56490792Sgshapiro of Sun Microsystems. 56590792Sgshapiro Allow specification of an empty realm via the authinfo ruleset. 56690792Sgshapiro This is necessary to interoperate as an SMTP AUTH client 56790792Sgshapiro with servers that do not support realms when using 56890792Sgshapiro CRAM-MD5. Problem noted by Bjoern Voigt of TU Berlin. 56990792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 57090792Sgshapiro server gets stuck while processing that command. Problem 57190792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 57290792Sgshapiro In addition to printing errors when parsing recipients during 57390792Sgshapiro command line invocations log them to make it simpler 57490792Sgshapiro to understand possible DSNs to postmaster. 57590792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 57690792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 57790792Sgshapiro instead of forcing localhost. 57890792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 57990792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 58090792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 58190792Sgshapiro noted by Neil Rickert of Northern Illinois University. 58290792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 58390792Sgshapiro dropping the connection during an SMTP transaction, stop 58490792Sgshapiro sending commands. This prevents bogus "Bad file number" 58590792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 58690792Sgshapiro Worcester Polytechnic Institute. 58790792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 58890792Sgshapiro almost always too small; do not guess the size at all. 58990792Sgshapiro New VENDOR_DEC for Compaq/DEC.

Problem 66790792Sgshapiro found by Michal Zalewski. 66890792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 66990792Sgshapiro privileges by disabling debugging (command line -d flag) 67090792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 67190792Sgshapiro used. Suggested by Michal Zalewski. 67290792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 67390792Sgshapiro Problem found by Michal Zalewski. 67490792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 67590792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 67690792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 67790792Sgshapiro If debugging is turned on (-d0.10) print not just the default 67890792Sgshapiro values for configuration file and pid file but also the 67990792Sgshapiro selected values. Problem noted by Brad Chapman. 68090792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 68190792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 68290792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 68390792Sgshapiro this only applied to hostname canonification. Problem 68490792Sgshapiro noted by Bill Fenner of AT&T Research. 68590792Sgshapiro Ignore comments in NIS host records when trying to find the 68690792Sgshapiro canonical name for a host. 68790792Sgshapiro When sendmail has extra privileges, limit mail submission command 68890792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 68990792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.).

You need to create a new user and 73290792Sgshapiro a new group before installing sendmail (both called smmsp by 73390792Sgshapiro default). The installation process tries to install 73490792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 73590792Sgshapiro default.

Suggested 74690792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 74790792Sgshapiro (IdS). 74890792Sgshapiro Fixed problem of a global variable being used for a timeout jump 74990792Sgshapiro point where the variable could become overused for more than 75090792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 75190792Sgshapiro a corrupted stack causing a core dump. The timeout is now 75290792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 75390792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 75490792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 75590792Sgshapiro checks (group ID of RunAsUser). This allows use of a 75690792Sgshapiro set-group-ID sendmail binary for initial message submission 75790792Sgshapiro and no set-user-ID root sendmail is needed. For details 75890792Sgshapiro see sendmail/SECURITY. 75990792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 76090792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 76190792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 76290792Sgshapiro with a fallback of sendmail.cf as configuration file. See 76390792Sgshapiro sendmail/SECURITY. 76490792Sgshapiro New configuration file option UseMSP to allow group writable queue 76590792Sgshapiro files if the group is the same as that of a set-group-ID 76690792Sgshapiro sendmail binary. See sendmail/SECURITY. 76790792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 76890792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 76990792Sgshapiro is sendmail.cf (to be backward compatible). This selection 77090792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 77190792Sgshapiro file: client or mta). See sendmail/SECURITY. 77290792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 77390792Sgshapiro command has been removed. 77490792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 77590792Sgshapiro at compile time or per host (ruleset). 77690792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 77790792Sgshapiro used to look up local mail recipients; the default value 77890792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 77990792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 78090792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 78190792Sgshapiro long, to accomodate envelope splitting. File systems with 78290792Sgshapiro a 14 character file name length limit are no longer 78390792Sgshapiro supported. 78490792Sgshapiro Recipient list used for delivery now gets internally ordered by 78590792Sgshapiro hostsignature (character string version of MX RR). This orders 78690792Sgshapiro recipients for the same MX RR's together meaning smaller 78790792Sgshapiro portions of the list need to be scanned (instead of the whole 78890792Sgshapiro list) each delivery() pass to determine piggybacking. The 78990792Sgshapiro significance of the change is better the larger the recipient 79090792Sgshapiro list. Hostsignature is now created during recipient list 79190792Sgshapiro creation rather than just before delivery. 79290792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 79390792Sgshapiro piggybacking (called coincidental) extended to coattail 79490792Sgshapiro piggybacking. Rather than complete MX RR matching 79590792Sgshapiro (coincidental) piggybacking is done if just the lowest value 79690792Sgshapiro preference matches (coattail). 79790792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 79890792Sgshapiro try other MX hosts if available. 79990792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 80090792Sgshapiro outgoing (client-side) SMTP Authentication. 80190792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 80290792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 80390792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 80490792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 80590792Sgshapiro A new ruleset authinfo can be used to return client side 80690792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 80790792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 80890792Sgshapiro removed in future versions. 80990792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 81090792Sgshapiro requires 334. Mercury 1.48 is a known offender. 81190792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 81290792Sgshapiro for the security layer in SMTP AUTH (SASL). See 81390792Sgshapiro doc/op/op.me for details. 81490792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 81590792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 81690792Sgshapiro signed the presented certificate, the CN and the MD5 hash 81790792Sgshapiro of the presented certificate, respectively. 81890792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 81990792Sgshapiro New ruleset srv_features to enable/disable certain features in the 82090792Sgshapiro server per connection. See doc/op/op.me for details. 82190792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 82290792Sgshapiro recipient; useful to decide whether a conection is secure 82390792Sgshapiro enough on a per recipient basis. 82490792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 82590792Sgshapiro for STARTTLS. 82690792Sgshapiro If no certificate has been requested, the macro {verify} has the 82790792Sgshapiro value "NOT". 82890792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 82990792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 83090792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 83190792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 83290792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 83390792Sgshapiro really required. This change results in a noticable 83490792Sgshapiro performance gains on most machines. Moreover, if shared 83590792Sgshapiro memory is in use, reuse the key several times. 83690792Sgshapiro Add queue groups which can be used to group queue directories with 83790792Sgshapiro the same behavior together. See doc/op/op.me for details. 83890792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 83990792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 84090792Sgshapiro are initially sorted which may result in faster envelope 84190792Sgshapiro splitting. If the mail is submitted directly from the 84290792Sgshapiro command line, then the value also limits the number of 84390792Sgshapiro processes to deliver the envelopes; if more envelopes are 84490792Sgshapiro created they are only queued up and must be taken care of 84590792Sgshapiro by a queue run. 84690792Sgshapiro The check for 'enough disk space' now pays attention to which file 84790792Sgshapiro system each queue directory resides in. 84890792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 84990792Sgshapiro New option QueueFileMode for the default permissions of queue files. 85090792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 85190792Sgshapiro group (one or more queues in a multi-queue environment 85290792Sgshapiro collected together) to process the same work list at the 85390792Sgshapiro same time. 85490792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 85590792Sgshapiro active queue runner processes. 85690792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 85790792Sgshapiro runners per queue group. 85890792Sgshapiro Queue member selection by substring pattern matching now allows 85990792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 86090792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 86190792Sgshapiro of the queue that match during processing. 86290792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 86390792Sgshapiro periodically forking a child to process the queue, a single 86490792Sgshapiro child is forked for each queue that sleeps between queue 86590792Sgshapiro runs. A SIGHUP signal can be sent to restart this 86690792Sgshapiro persistent queue runner. 86790792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 86890792Sgshapiro sendmail process which only runs the queue at an interval: 86990792Sgshapiro sendmail -q15m). 87090792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 87190792Sgshapiro Proposed by Thom O'Connor. 87290792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 87390792Sgshapiro unless the new -qf option or -v is used. 87490792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 87590792Sgshapiro several queue runners are started by hand to avoid contention. 87690792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 87790792Sgshapiro of the qf file (older entries first). 87890792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 87990792Sgshapiro a client to specify an amount of time within which an e-mail 88090792Sgshapiro should be delivered. New option DeliverByMin added to set the 88190792Sgshapiro minimum amount of time or disable the extension. 88290792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 88390792Sgshapiro not allowed unless escaped or quoted. 88490792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 88590792Sgshapiro by Leif Johansson of Stockholm University, which was based on 88690792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 88790792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 88890792Sgshapiro Technology, Stockholm, Sweden. 88990792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 89090792Sgshapiro behavior (no MX lookups), put the name in square brackets. 89190792Sgshapiro Proposed by Thom O'Connor. 89290792Sgshapiro Use shared memory to store free space of filesystems that are used 89390792Sgshapiro for queues, if shared memory is available and if a key is set 89490792Sgshapiro via SharedMemoryKey. This minimizes the number of system 89590792Sgshapiro calls to check the available space. See doc/op/op.me for 89690792Sgshapiro details. 89790792Sgshapiro If shared memory is compiled in the option -bP can be used to print 89890792Sgshapiro the number of entries in the queue(s). 89990792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 90090792Sgshapiro and the usual documentation for details. 90190792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 90290792Sgshapiro Remove '-U' (initial user submission) command line option as 90390792Sgshapiro announced in 8.10. 90490792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 90590792Sgshapiro New macro {addr_type} which contains whether the current address is 90690792Sgshapiro an envelope sender or recipient address. Suggested by 90790792Sgshapiro Neil Rickert of Northern Illinois University. 90890792Sgshapiro Two new options for host maps: -d (retransmission timeout), 90990792Sgshapiro -r (number of retries). 91090792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 91190792Sgshapiro separator such that a lookup can return both an attribute 91290792Sgshapiro and value separated by the given separator. 91390792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 91490792Sgshapiro to map class arith. 91590792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 91690792Sgshapiro (errors that occur when sending an error message) are dropped. 91790792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 91890792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 91990792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 92090792Sgshapiro requirements for files containing secret keys. This is 92190792Sgshapiro necessary for the MSP if client authentification is used. 92290792Sgshapiro Properly handle quoted filenames for class files (to allow for 92390792Sgshapiro filenames with spaces). 92490792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 92590792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 92690792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 92790792Sgshapiro {if_addr_out} address of interface of outgoing connection. 92890792Sgshapiro {if_family_out} family of interface of outgoing connection. 92990792Sgshapiro The latter two are only set if the interface does not belong 93090792Sgshapiro to the loopback net. 93190792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 93290792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 93390792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 93490792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 93590792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 93690792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 93790792Sgshapiro all connections for a single delivery attempt to succeed. 93890792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 93990792Sgshapiro a threshold number of recipients has been rejected (option 94090792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 94190792Sgshapiro Development Group. 94290792Sgshapiro New option DelayLA to delay connections if the load averages 94390792Sgshapiro exceeds the specified value. The default of 0 does not 94490792Sgshapiro change the previous behavior. A value greater than 0 94590792Sgshapiro will cause sendmail to sleep for one second on most 94690792Sgshapiro SMTP commands and before accepting connections if that 94790792Sgshapiro load average is exceeded. 94890792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 94990792Sgshapiro recipients that are sent during a connection to a mailer. 95090792Sgshapiro This also introduces a new mailer field 'r' which defines 95190792Sgshapiro the maximum number of recipients (defaults to 100). 95290792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 95390792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 95490792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 95590792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 95690792Sgshapiro instead. 95790792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 95890792Sgshapiro builtin mailer pathnames. Use TCP instead. 95990792Sgshapiro PH map code updated to use the new libphclient API instead of the 96090792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 96190792Sgshapiro University of Illinois at Urbana-Champaign. 96290792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 96390792Sgshapiro for direct (command line) submissions. 96490792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 96590792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 96690792Sgshapiro Hagino of the KAME Project. 96790792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 96890792Sgshapiro whose content is rewritten similar to Reply-To:. 96990792Sgshapiro Proposed by Andrzej Filip. 97090792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 97190792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 97290792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 97390792Sgshapiro AUTH/STARTTLS related logfile entries. 97490792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 97590792Sgshapiro before logging. 97690792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 97790792Sgshapiro (at LogLevel 9/10 or higher). 97890792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 97990792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 98090792Sgshapiro in which most commands are rejected due to check_relay or 98190792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 98290792Sgshapiro Change logging format for cloned envelopes to be similar to that for 98390792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 98490792Sgshapiro of the Universitat Regensburg. 98590792Sgshapiro Added libsm, a C library of general purpose abstractions including 98690792Sgshapiro assertions, tracing and debugging with named debug categories, 98790792Sgshapiro exception handling, malloc debugging, resource pools, 98890792Sgshapiro portability abstractions, and an extensible buffered I/O 98990792Sgshapiro package. It will at some point replace libsmutil. 99090792Sgshapiro See libsm/index.html for details. 99190792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 99290792Sgshapiro care of by fork() and exit(). 99390792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 99490792Sgshapiro more consistent portablity amongst different platforms 99590792Sgshapiro new and old (from new libsm). 99690792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 99790792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 99890792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 99990792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 100090792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 100190792Sgshapiro synchronizations calls. 100290792Sgshapiro Add per-recipient status information to mailq -v output. 100390792Sgshapiro T_ANY queries are no longer used by sendmail. 100490792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 100590792Sgshapiro too (see include/sm/cdefs.h for more info). 100690792Sgshapiro sendmail -d now has general support for named debug categories. 100790792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 100890792Sgshapiro for details. 100990792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 101090792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 101190792Sgshapiro generated by this condition were illegal (not RFC conform). 101290792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 101390792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 101490792Sgshapiro mailer and the recipient has hence been rejected during the 101590792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 101690792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 101790792Sgshapiro that do not have postmaster defined. If an email was sent 101890792Sgshapiro from an address to which a DSN cannot be returned and 101990792Sgshapiro in which at least one recipient address is non-deliverable, 102090792Sgshapiro then that email had been delivered in each queue run. 102190792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 102290792Sgshapiro degli Studi dell'Insubria. 102390792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 102490792Sgshapiro i.e., the corresponding code is always compiled in now. 102590792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 102690792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 102790792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 102890792Sgshapiro attempting to canonify a hostname, some broken nameservers 102990792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 103090792Sgshapiro lookups. If you want to excuse this behavior, use this new 103190792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 103290792Sgshapiro Mark Roth of the University of Illinois at 103390792Sgshapiro Urbana-Champaign. 103490792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 103590792Sgshapiro noted by Joy Latten of IBM. 103690792Sgshapiro ConnectionRateThrottle limits the number of connections per second 103790792Sgshapiro to each daemon individually, not the overall number of 103890792Sgshapiro connections. 103990792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 104090792Sgshapiro sendmail to use a default alias schema as outlined in the 104190792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 104290792Sgshapiro cf/README. 104390792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 104490792Sgshapiro the first character after the class name is not a '/' or a 104590792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 104690792Sgshapiro rest of the line will be parsed as a map lookup. This 104790792Sgshapiro allows classes to be filled via a map lookup. See op.me 104890792Sgshapiro for more syntax information. Specifically, this can be 104990792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 105090792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 105190792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 105290792Sgshapiro example). 105390792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 105490792Sgshapiro the default schema used in the above two items. 105590792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 105690792Sgshapiro warning if a program being run from a mailer or file class 105790792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 105890792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 105990792Sgshapiro if a program being run from a mailer or file class 106090792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 106190792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 106290792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 106390792Sgshapiro (without quotes) will disable this and return to the 106490792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 106590792Sgshapiro Suggested by Bryan Stansell of GNAC. 106690792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 106790792Sgshapiro HELO/EHLO commands. 106890792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 106990792Sgshapiro possible protocol family which may be used for outgoing 107090792Sgshapiro connections. Restrictions placed on one family only affect 107190792Sgshapiro outgoing connections on that particular family. Because of 107290792Sgshapiro this change, the ${client_flags} macro is not set until the 107390792Sgshapiro connection is established. Based on patch from Motonori 107490792Sgshapiro Nakamura of Kyoto University. 107590792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 107690792Sgshapiro when the -bv option is given by users who are neither root 107790792Sgshapiro nor the TrustedUser so users can not read private aliases, 107890792Sgshapiro forwards, or :include: files. It also will override the -v 107990792Sgshapiro (verbose) command line option. 108090792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 108190792Sgshapiro address can't be used for the outgoing connection, fall 108290792Sgshapiro back to the settings in ClientPortOptions (if set). 108390792Sgshapiro Problem noted by John Beck of Sun Microsystems. 108490792Sgshapiro New named config file rule check_data for DATA command (input: 108590792Sgshapiro number of recipients). Based on patch from Mark Roth of 108690792Sgshapiro the University of Illinois at Urbana-Champaign. 108790792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 108890792Sgshapiro can be specified using the '#' option character. For 108990792Sgshapiro example, 'ETRN #queuegroup'. 109090792Sgshapiro If an LDAP server times out or becomes unavailable, close the 109190792Sgshapiro current connection and reopen to get to one of the fallback 109290792Sgshapiro servers. Patch from Paul Hilchey of the University of 109390792Sgshapiro British Columbia. 109490792Sgshapiro Make default error number on $#error messages 550 instead of 501 109590792Sgshapiro because 501 is not allowed on all commands. 109690792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 109790792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 109890792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 109990792Sgshapiro if required. 110090792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 110190792Sgshapiro class instead. 110290792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 110390792Sgshapiro "IPv6:" tag to identify the address properly. For example, 110490792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 110590792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 110690792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 110790792Sgshapiro MTA is running. For example, during a queue run. 110890792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 110990792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 111090792Sgshapiro Nelson of IBM. 111190792Sgshapiro The maximum number of commands before the MTA slows down when too 111290792Sgshapiro many "light weight" commands have been received are now 111390792Sgshapiro configurable during compile time. The current values and 111490792Sgshapiro their defaults are: 111590792Sgshapiro MAXBADCOMMANDS 25 unknown commands 111690792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 111790792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 111890792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 111990792Sgshapiro MAXETRNCOMMANDS 8 ETRN 112090792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 112190792Sgshapiro Costales of SL3D, Inc. 112290792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 112390792Sgshapiro ${MyMacro} is defined but also that it is not empty. 112490792Sgshapiro Properly quote usernames with special characters if they are used 112590792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 112690792Sgshapiro Meteorological Institute. 112790792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 112890792Sgshapiro messages for messages for mailing list expanded addresses 112990792Sgshapiro which are not delivered on the initial attempt. 113090792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 113190792Sgshapiro the final dot has been sent to avoid affecting future 113290792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 113390792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 113490792Sgshapiro file systems that require to call fsync() for a directory 113590792Sgshapiro if the meta-data in it has been changed. This should be 113690792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 113790792Sgshapiro See sendmail/README for further information. 113890792Sgshapiro Avoid file locking deadlock when updating the statistics file if 113990792Sgshapiro sendmail is signaled to terminate. Problem noted by 114090792Sgshapiro Christophe Wolfhugel of France Telecom. 114190792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 114290792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 114390792Sgshapiro the Finnish Meteorological Institute. 114490792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 114590792Sgshapiro from Peter A. Friend of EarthLink. 114690792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 114790792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 114890792Sgshapiro flora.ca. 114990792Sgshapiro Portability: 115090792Sgshapiro Remove support for AIX 2, which supports only 14 character 115190792Sgshapiro filenames and is outdated anyway. Suggested by 115290792Sgshapiro Valdis Kletnieks of Virginia Tech. 115390792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 115490792Sgshapiro i.e., use default /usr/sbin, change owner/group 115590792Sgshapiro of man pages and user-executable to root/sys, set 115690792Sgshapiro optimization limit to 0 (unlimited). Based on patch 115790792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 115890792Sgshapiro Hurtta of the Finnish Meteorological Institute. 115990792Sgshapiro Do not assume LDAP support is installed by default under 116090792Sgshapiro Solaris 8 and later. 116190792Sgshapiro Add support for OpenUNIX. 116290792Sgshapiro CONFIG: Increment version number of config file to 10. 116390792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 116490792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 116590792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 116690792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 116790792Sgshapiro temporary lookup failures. 116890792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 116990792Sgshapiro action to be taken by aborting the search for domain names 117090792Sgshapiro or IP nets. 117190792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 117290792Sgshapiro relay address as long as the other part allows the email 117390792Sgshapiro to get through. 117490792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 117590792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 117690792Sgshapiro entry like user+*@domain. This allows handling of details by 117790792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 117890792Sgshapiro introduced to match only non-empty details of addresses. 117990792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 118090792Sgshapiro and hence there is no required order within the MAILER 118190792Sgshapiro section anymore except for MAILER(`uucp') which must come 118290792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 118390792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 118490792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 118590792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 118690792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 118790792Sgshapiro in the access map which returns OK or RELAY actually 118890792Sgshapiro terminates check_* ruleset checking. 118990792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 119090792Sgshapiro tls_rcpt, see cf/README for details. 119190792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 119290792Sgshapiro STARTTLS has been used to "(version=${tls_version} 119390792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 119490792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 119590792Sgshapiro options friends/haters instead of "To:" and enable 119690792Sgshapiro specification of whole domains instead of just users. 119790792Sgshapiro Notice: this change is not backward compatible. 119890792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 119990792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 120090792Sgshapiro cf/README for details. 120190792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 120290792Sgshapiro the access map. Proposed by Randall Winchester of the 120390792Sgshapiro University of Maryland. 120490792Sgshapiro CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for 120590792Sgshapiro the local mailer. Proposed by Ingo Brueckl of Wupper Online. 120690792Sgshapiro CONFIG: confRELAY_MSG/confREJECT_MSG can override the default 120790792Sgshapiro messages for an unauthorized relaying attempt/for access 120890792Sgshapiro map entries with RHS REJECT, respectively. 120990792Sgshapiro CONFIG: FEATURE(`always_add_domain') takes an optional argument 121090792Sgshapiro to specify another domain to be added instead of the local one. 121190792Sgshapiro Suggested by Richard H. Gumpertz of Computer Problem 121290792Sgshapiro Solving. 121390792Sgshapiro CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific 121490792Sgshapiro options, see doc/op/op.me for details. 121590792Sgshapiro CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for 121690792Sgshapiro the security layer in SMTP AUTH (SASL). 121790792Sgshapiro CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated 121890792Sgshapiro immediately. 121990792Sgshapiro CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which 122090792Sgshapiro allows checking of the return values of the DNS lookups. 122190792Sgshapiro See cf/README for details. 122290792Sgshapiro CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for 122390792Sgshapiro temporary lookup failures. 122490792Sgshapiro CONFIG: New option confDELIVER_BY_MIN to specify minimum time for 122590792Sgshapiro Deliver By (RFC 2852) or to turn off the extension. 122690792Sgshapiro CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared 122790792Sgshapiro memory use. 122890792Sgshapiro CONFIG: New FEATURE(`compat_check') to look up a key consisting 122990792Sgshapiro of the sender and the recipient address delimited by the 123090792Sgshapiro string "<@>", e.g., sender@sdomain<@>recipient@rdomain, 123190792Sgshapiro in the access map. Based on code contributed by Mathias 123290792Sgshapiro Koerber of Singapore Telecommunications Ltd. 123390792Sgshapiro CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user 123490792Sgshapiro file. Suggested by John Beck of Sun Microsystems. 123590792Sgshapiro CONFIG: Don't use MAILER-DAEMON for error messages delivered 123690792Sgshapiro via LMTP. Problem reported by Larry Greenfield of CMU. 123790792Sgshapiro CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of 123890792Sgshapiro the recipient host if LUSER_RELAY is used. 123990792Sgshapiro CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the 124090792Sgshapiro +detail portion of the address when passing address to 124190792Sgshapiro local delivery agent. Disables alias and .forward +detail 124290792Sgshapiro stripping. Only use if LDA supports this. 124390792Sgshapiro CONFIG: Removed deprecated FEATURE(`rbl'). 124490792Sgshapiro CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() 124590792Sgshapiro which allow you to specify 'equivalent' hosts for LDAP 124690792Sgshapiro Routing lookups. Equivalent hostnames are replaced by the 124790792Sgshapiro masquerade domain name for lookups. See cf/README for 124890792Sgshapiro additional details. 124990792Sgshapiro CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which 125090792Sgshapiro instructs the rulesets on what to do if the address being 125190792Sgshapiro looked up has +detail information. See cf/README for more 125290792Sgshapiro information. 125390792Sgshapiro CONFIG: When chosing a new destination via LDAP Routing, also look 125490792Sgshapiro up the new routing address/host in the mailertable.

Problem 158173188Sgshapiro noted by Orion Poplawski of CQG, Inc. 158273188Sgshapiro CONTRIB: buildvirtuser: Substitute current domain for $DOMAIN and 158373188Sgshapiro current left hand side for $LHS in virtuser files. 158473188Sgshapiro DEVTOOLS: Do not pass make targets to recursive Build invocations. 158573188Sgshapiro Problem noted by Jeff Bronson of J.D. Bronson, Inc. 158673188Sgshapiro MAIL.LOCAL: In LMTP mode, do not return errors regarding problems 158773188Sgshapiro storing the temporary message file until after the remote 158873188Sgshapiro side has sent the final DATA termination dot. Problem 158973188Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic 159073188Sgshapiro Institute. 159173188Sgshapiro MAIL.LOCAL: If LMTP mode is set, give a temporary error if users 159273188Sgshapiro are also specified on the command line. Patch from 159373188Sgshapiro Motonori Nakamura of Kyoto University. 159473188Sgshapiro PRALIASES: Skip over AliasFile specifications which aren't based on 159573188Sgshapiro database files (i.e., only show dbm, hash, and btree). 159673188Sgshapiro Renamed Files: 159773188Sgshapiro devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x 159873188Sgshapiro 159971345Sgshapiro8.11.2/8.11.2 2000/12/29 160071345Sgshapiro Prevent a segmentation fault when trying to set a class in 160171345Sgshapiro address test mode due to a negative array index. Audit 160271345Sgshapiro other array indexing. This bug is not believed to be 160371345Sgshapiro exploitable. Noted by Michal Zalewski of the "Internet for 160471345Sgshapiro Schools" project (IdS). 160571345Sgshapiro Add an FFR (for future release) to drop privileges when using 160671345Sgshapiro address test mode. This will be turned on in 8.12.

Problem noted by Valdis 165071345Sgshapiro Kletnieks of Virginia Tech. 165171345Sgshapiro When delivering to a file directly from an alias, do not call 165271345Sgshapiro initgroups(); instead use the DefaultUser group information. 165371345Sgshapiro Problem noted by Marc Schaefer of ALPHANET NF. 165471345Sgshapiro RunAsUser now overrides the ownership of the control socket, if 165571345Sgshapiro created. Otherwise, sendmail can not remove it upon 165671345Sgshapiro close. Problem noted by Werner Wiethege. 165771345Sgshapiro Fix ConnectionRateThrottle counting as the option is the number of 165871345Sgshapiro overall connections, not the number of connections per 165971345Sgshapiro socket. A future version may change this to per socket 166071345Sgshapiro counting. 166171345Sgshapiro Portability: 166271345Sgshapiro Clean up libsmdb so it functions properly on platforms 166371345Sgshapiro where sizeof(u_int32_t) != sizeof(size_t).

Problem 184264562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 184364562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 184464562Sgshapiro Implementation influenced by the example programs of 184564562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 184664562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 184764562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 184864562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 184964562Sgshapiro cf/README and doc/op/op.*. 185064562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 185164562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 185264562Sgshapiro ${server_name}, and ${server_addr}. These are documented 185364562Sgshapiro in cf/README and doc/op/op.*. 185464562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 185564562Sgshapiro random data. 185664562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 185764562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 185864562Sgshapiro try to use STARTTLS despite the security problems. 185964562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 186064562Sgshapiro support encryption. Based on code contributed by Tim 186164562Sgshapiro Martin of CMU. 186264562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 186364562Sgshapiro strength factor. 186464562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 186564562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 186664562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 186764562Sgshapiro of CMU. 186864562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 186964562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 187064562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 187164562Sgshapiro Fix the default family selection for DaemonPortOptions. As 187264562Sgshapiro documented, unless a family is specified in a 187364562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 187464562Sgshapiro also the default if no DaemonPortOptions value is set. 187564562Sgshapiro Therefore, IPv6 users should configure additional sockets 187664562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 187764562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 187864562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 187964562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 188064562Sgshapiro the interface information for an outgoing connection. 188164562Sgshapiro Not doing so was creating a mismatch between the socket 188264562Sgshapiro family and address used in subsequent connections if the 188364562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 188464562Sgshapiro by John Beck of Sun Microsystems. 188564562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 188664562Sgshapiro family based on the IP address. ${if_family} is no longer 188764562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 188864562Sgshapiro of Sun Microsystems. 188964562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 189064562Sgshapiro macros for both the incoming interface address/family and 189164562Sgshapiro the outgoing interface address/family. In order for M=b 189264562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 189364562Sgshapiro the incoming information in the queue file for later 189464562Sgshapiro delivery attempts. 189564562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 189664562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 189764562Sgshapiro smoe.org. 189864562Sgshapiro Add more vigilance in checking for putc() errors on output streams 189964562Sgshapiro to protect from a bug in Solaris 2.6's putc().

Problem noted by Ari Heikkinen of Pohjois-Savo 192164562Sgshapiro Polytechnic. 192264562Sgshapiro Under the proper circumstances, failed connections would be recorded 192364562Sgshapiro as "Bad file number" instead of "Connection failed" in the 192464562Sgshapiro queue file and persistent host status. Problem noted by 192564562Sgshapiro Graeme Hewson of Oracle. 192664562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 192764562Sgshapiro within the hoststatus directory (e.g., lost+found). 192864562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 192964562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 193064562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 193164562Sgshapiro If a message data file can't be opened at delivery time, panic and 193264562Sgshapiro abort the attempt instead of delivering a message that 193364562Sgshapiro states "<<< No Message Collected >>>". 193464562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 193564562Sgshapiro restrictive.

Problem noted 194364562Sgshapiro by Valdis Kletnieks of Virginia Tech. 194464562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 194564562Sgshapiro only the first to open the connection is allowed to close 194664562Sgshapiro it so a later map close doesn't break the connection for 194764562Sgshapiro other maps.

Problem noted by Michal Zalewski of the 220364562Sgshapiro "Internet for Schools" project (IdS). 220464562Sgshapiro SECURITY: There is a potential for a denial of service attack if 220564562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 220664562Sgshapiro sendmail process while it is rebuilding the aliases file 220764562Sgshapiro (leaving it in an inconsistent state). This option and 220864562Sgshapiro its use is deprecated and will be removed from a future 220964562Sgshapiro version of sendmail. 221064562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 221164562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 221264562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 221364562Sgshapiro (IdS). 221464562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 221564562Sgshapiro a large number of files. See cf/README for more details. 221664562Sgshapiro The directory structure of the distribution has changed slightly 221764562Sgshapiro for easier code sharing among the programs. 221864562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 221964562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 222064562Sgshapiro which hold the client's authentication credentials, 222164562Sgshapiro the mechanism used for authentication, and the 222264562Sgshapiro authorization identity (i.e., the AUTH= parameter if 222364562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 222464562Sgshapiro On systems which use the Torek stdio library (all of the BSD 222564562Sgshapiro distributions), use memory-buffered files to reduce 222664562Sgshapiro file system overhead by not creating temporary files on 222764562Sgshapiro disk. Contributed by Exactis.com, Inc. 222864562Sgshapiro New option DataFileBufferSize to control the maximum size of a 222964562Sgshapiro memory-buffered data (df) file before a disk-based file is 223064562Sgshapiro used. Contributed by Exactis.com, Inc. 223164562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 223264562Sgshapiro memory-buffered transcript (xf) file before a disk-based 223364562Sgshapiro file is used. Contributed by Exactis.com, Inc. 223464562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 223564562Sgshapiro now listen on several different ports. Use: 223664562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 223764562Sgshapiro to run a Message Submission Agent (MSA); this is turned 223864562Sgshapiro on by default in m4-generated .cf files; it can be turned 223964562Sgshapiro off with FEATURE(`no_default_msa'). 224064562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 224164562Sgshapiro begin using RFC 2476 Message Submission for initial user 224264562Sgshapiro message submission. XUSR may disappear from a future release. 224364562Sgshapiro The new '-G' (relay (gateway) submission) command line option 224464562Sgshapiro indicates that the message being submitted from the command 224564562Sgshapiro line is for relaying, not initial submission. This means 224664562Sgshapiro the message will be rejected if the addresses are not fully 224764562Sgshapiro qualified and no canonicalization will be done. Future 224864562Sgshapiro releases may even reject improperly formed messages. 224964562Sgshapiro The '-U' (initial user submission) command line option is 225064562Sgshapiro deprecated and may be removed from a future release. 225164562Sgshapiro Mail user agents should begin using '-G' to indicate that 225264562Sgshapiro this is a relay submission (the inverse of -U). 225364562Sgshapiro The next release of sendmail will assume that any message submitted 225464562Sgshapiro from the command line is an initial user submission and act 225564562Sgshapiro accordingly. 225664562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 225764562Sgshapiro program or deliver to file as the owner of that file, the 225864562Sgshapiro address is marked as unsafe. This means if RunAsUser is 225964562Sgshapiro set, users won't be able to use programs or delivery to 226064562Sgshapiro files in their .forward files. Administrators can override 226164562Sgshapiro this by setting the DontBlameSendmail option to the new 226264562Sgshapiro setting NonRootSafeAddr. 226364562Sgshapiro Allow group or world writable directories if the sticky bit is set 226464562Sgshapiro on the directory and DontBlameSendmail is set to 226564562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 226664562Sgshapiro InCert Software. 226764562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 226864562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 226964562Sgshapiro set in the DontBlameSendmail option. Requested by many. 227064562Sgshapiro New Timeout.control option to limit the total time spent satisfying 227164562Sgshapiro a control socket request. 227264562Sgshapiro New Timeout.resolver options for controlling BIND resolver 227364562Sgshapiro settings: 227464562Sgshapiro Timeout.resolver.retrans 227564562Sgshapiro Sets the resolver's retransmission time interval (in 227664562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 227764562Sgshapiro and Timeout.resolver.retrans.normal. 227864562Sgshapiro Timeout.resolver.retrans.first 227964562Sgshapiro Sets the resolver's retransmission time interval (in 228064562Sgshapiro seconds) for the first attempt to deliver a message. 228164562Sgshapiro Timeout.resolver.retrans.normal 228264562Sgshapiro Sets the resolver's retransmission time interval (in 228364562Sgshapiro seconds) for all resolver lookups except the first 228464562Sgshapiro delivery attempt. 228564562Sgshapiro Timeout.resolver.retry 228664562Sgshapiro Sets the number of times to retransmit a resolver 228764562Sgshapiro query. Sets both Timeout.resolver.retry.first 228864562Sgshapiro and Timeout.resolver.retry.normal. 228964562Sgshapiro Timeout.resolver.retry.first 229064562Sgshapiro Sets the number of times to retransmit a resolver 229164562Sgshapiro query for the first attempt to deliver a message. 229264562Sgshapiro Timeout.resolver.retry.normal 229364562Sgshapiro Sets the number of times to retransmit a resolver 229464562Sgshapiro query for all resolver lookups except the first 229564562Sgshapiro delivery attempt. 229664562Sgshapiro Contributed by Exactis.com, Inc. 229764562Sgshapiro Support multiple queue directories. To use multiple queues, supply 229864562Sgshapiro a QueueDirectory option value ending with an asterisk. For 229964562Sgshapiro example, /var/spool/mqueue/q* will use all of the 230064562Sgshapiro directories or symbolic links to directories beginning with 230164562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 230264562Sgshapiro mind, the queue directory structure should not be changed 230364562Sgshapiro while sendmail is running. Queue runs create a separate 230464562Sgshapiro process for running each queue unless the verbose flag is 230564562Sgshapiro given on a non-daemon queue run. New items are randomly 230664562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 230764562Sgshapiro Support different directories for qf, df, and xf queue files; if 230864562Sgshapiro subdirectories or symbolic links to directories of those names 230964562Sgshapiro exist in the queue directories, they are used for the 231064562Sgshapiro corresponding queue files. Keep in mind, the queue 231164562Sgshapiro directory structure should not be changed while sendmail is 231264562Sgshapiro running. Proposed by Mathias Koerber of Singapore 231364562Sgshapiro Telecommunications Ltd. 231464562Sgshapiro New queue file naming system which uses a filename guaranteed to be 231564562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 231664562Sgshapiro without fancy file system locking. Queued items can be 231764562Sgshapiro moved between queues easily. Contributed by Exactis.com, 231864562Sgshapiro Inc. 231964562Sgshapiro Messages which are undeliverable due to temporary address failures 232064562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 232164562Sgshapiro set. Contributed by Exactis.com, Inc. 232264562Sgshapiro New command line option '-L tag' which sets the identifier used for 232364562Sgshapiro syslog. Contributed by Exactis.com, Inc. 232464562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 232564562Sgshapiro avoids opening and reading each queue file when preparing 232664562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 232764562Sgshapiro Shared memory counters and microtimers functionality has been 232864562Sgshapiro donated by Exactis.com, Inc. 232964562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 233064562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 233164562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 233264562Sgshapiro being added. Suggested by Michael K. Sanders. 233364562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 233464562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 233564562Sgshapiro and John Beck of Sun Microsystems. 233664562Sgshapiro In low-disk space situations, where sendmail would previously refuse 233764562Sgshapiro connections, still accept them, but only allow ETRN commands. 233864562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 233964562Sgshapiro Ltd. 234064562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 234164562Sgshapiro on systems which support them. This can be used with LMTP 234264562Sgshapiro local delivery agents which listen on a named socket. An 234364562Sgshapiro example mailer might be: 234464562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 234564562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 234664562Sgshapiro A=FILE /var/run/lmtpd 234764562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 234864562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 234964562Sgshapiro instead. 235064562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 235164562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 235264562Sgshapiro connections), IPC (which will be deprecated in a future 235364562Sgshapiro version), and FILE (for UNIX domain socket delivery). 235464562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 235564562Sgshapiro flags. 235664562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 235764562Sgshapiro body of the original message on delivery status 235864562Sgshapiro notifications. 235964562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 236064562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 236164562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 236264562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 236364562Sgshapiro Steve Schweinhart of America Online. 236464562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 236564562Sgshapiro not be set after rulesets are defined. Suggested by 236664562Sgshapiro Mitchell Blank Jr of Exec-PC. 236764562Sgshapiro Do not report temporary failure on delivery to files. In 236864562Sgshapiro interactive delivery mode, this would result in two SMTP 236964562Sgshapiro responses after the DATA command. Problem noted by 237064562Sgshapiro Nik Conwell of Boston University. 237164562Sgshapiro Check file close when mailing to files. Problem noted by Nik 237264562Sgshapiro Conwell of Boston University. 237364562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 237464562Sgshapiro Curtis W. Hillegas of Princeton University. 237564562Sgshapiro Always bind to the LDAP server regardless of whether you are using 237664562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 237764562Sgshapiro @Home Network. 237864562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 237964562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 238064562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 238164562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 238264562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 238364562Sgshapiro similar to check_rcpt etc. 238464562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 238564562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 238664562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 238764562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 238864562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 238964562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 239064562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 239164562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 239264562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 239364562Sgshapiro the corresponding DSN parameter values. Proposed by 239464562Sgshapiro Mathias Herberts. 239564562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 239664562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 239764562Sgshapiro before the message has been collected, thereafter it holds 239864562Sgshapiro the message size as computed by sendmail (and can be used 239964562Sgshapiro in check_compat). 240064562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 240164562Sgshapiro sendmail is using instead of the value of the DeliveryMode 240264562Sgshapiro option. 240364562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 240464562Sgshapiro Drop explicit From: if same as what would be generated only if it is 240564562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 240664562Sgshapiro Write pid to file also if sendmail only processes the queue. 240764562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 240864562Sgshapiro Log "low on disk space" only when necessary. 240964562Sgshapiro New macro ${load_avg} can be used to check the current load average. 241064562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 241164562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 241264562Sgshapiro is set. 241364562Sgshapiro Flag -S for maps to specify the character which is substituted 241464562Sgshapiro for spaces (instead of the default given by O BlankSub). 241564562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 241664562Sgshapiro This flag is set by default for the host map. Based on a 241764562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 241864562Sgshapiro Open maps only on demand, not at startup. 241964562Sgshapiro Log warning about unsupported IP address families. 242064562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 242164562Sgshapiro of the sum of all headers. This can be used to prevent 242264562Sgshapiro a denial-of-service attack. 242364562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 242464562Sgshapiro headers and parameters within those headers. This option 242564562Sgshapiro is intended to protect mail user agents from buffer 242664562Sgshapiro overflow attacks. 242764562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 242864562Sgshapiro alias recursion. 242964562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 243064562Sgshapiro Map type syslog to log the key via syslogd. 243164562Sgshapiro Entries in the alias file can be continued by putting a backslash 243264562Sgshapiro directly before the newline. 243364562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 243464562Sgshapiro dead.letter file, formerly hardcoded to 243564562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 243664562Sgshapiro default), sendmail will not attempt to save to a 243764562Sgshapiro system-wide dead.letter file if it can not bounce the mail 243864562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 243964562Sgshapiro file as it has in the past when the dead.letter file 244064562Sgshapiro could not be opened. 244164562Sgshapiro New option PidFile to define the location of the pid file. The 244264562Sgshapiro value of this option is macro expanded. 244364562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 244464562Sgshapiro process title shown in 'ps' listings. 244564562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 244664562Sgshapiro (along with the already existing macros): 244764562Sgshapiro ${daemon_info} Daemon information, e.g. 244864562Sgshapiro SMTP+queueing@00:30:00 244964562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 245064562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 245164562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 245264562Sgshapiro ${daemon_port} Daemon port, e.g., 25 245364562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 245464562Sgshapiro New macros especially for virtual hosting: 245564562Sgshapiro ${if_name} hostname of interface of incoming connection. 245664562Sgshapiro ${if_addr} address of interface of incoming connection. 245764562Sgshapiro The latter is only set if the interface does not belong to the 245864562Sgshapiro loopback net. 245964562Sgshapiro If a message being accepted via a method other than SMTP and 246064562Sgshapiro would be rejected by a header check, do not send the message. 246164562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 246264562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 246364562Sgshapiro Provide header value as quoted string in the macro 246464562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 246564562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 246664562Sgshapiro The length of the header value is stored in ${hdrlen}. 246764562Sgshapiro H*: allows to specify a default ruleset for header checks. This 246864562Sgshapiro ruleset will only be called if the individual header does 246964562Sgshapiro not have its own ruleset assigned. Suggested by Jan 247064562Sgshapiro Krueger of Unix-AG of University of Hannover. 247164562Sgshapiro The name of the header field stored in ${hdr_name}. 247264562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 247364562Sgshapiro removed if the config file version is greater than or equal 247464562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 247564562Sgshapiro input "token (1)" but does not match "token". 247664562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 247764562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 247864562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 247964562Sgshapiro Ericsson. 248064562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 248164562Sgshapiro messages with 8-bit text in headers. Problem noted by 248264562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 248364562Sgshapiro of Ericsson. 248464562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 248564562Sgshapiro modified database map file. Problem noted by Chris Adams 248664562Sgshapiro of Renaissance Internet Services. 248764562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 248864562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 248964562Sgshapiro queue up the message instead of bouncing it. 249064562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 249164562Sgshapiro standard does not provide any indication of what to do when 249264562Sgshapiro something other than 250 is received. Based on a patch 249364562Sgshapiro from Steve Schweinhart of America Online. 249464562Sgshapiro New option TrustedUser allows to specify a user who can own 249564562Sgshapiro important files instead of root. This requires HASFCHOWN. 249664562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 249764562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 249864562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 249964562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 250064562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 250164562Sgshapiro $? tests also whether the macro is non-null. 250264562Sgshapiro Print an error message if a mailer definition contains an invalid 250364562Sgshapiro equate name. 250464562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 250564562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 250664562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 250764562Sgshapiro mailer to return after sending all data to it. 250864562Sgshapiro Only free memory from the process list when adding a new process 250964562Sgshapiro into a previously filled slot. Previously, the memory was 251064562Sgshapiro freed at removal time. Since removal can happen in a 251164562Sgshapiro signal handler, this may leave the memory map in an 251264562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 251364562Sgshapiro David Cooley of Colby College. 251464562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 251564562Sgshapiro local users in the passwd file. The UserDB code has 251664562Sgshapiro already decided the message will be passed to another host 251764562Sgshapiro for processing. Fix from Tony Landells of Burdett 251864562Sgshapiro Buckeridge Young Limited. 251964562Sgshapiro Support LDAP authorization via either a file containing the 252064562Sgshapiro password or Kerberos V4 using the new map options 252164562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 252264562Sgshapiro distinguished_name is who to login as. The method can be 252364562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 252464562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 252564562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 252664562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 252764562Sgshapiro of Stanford University. 252864562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 252964562Sgshapiro deprecated and will be removed in a future version. 253064562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 253164562Sgshapiro and the map has the column delimiter set, it turns that 253264562Sgshapiro response into a delimiter separated string. The LDAP map 253364562Sgshapiro will traverse multiple entries as well. LDAP alias maps 253464562Sgshapiro automatically set the column delimiter to the comma. 253564562Sgshapiro Based on patch from Booker Bense of Stanford University and 253664562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 253764562Sgshapiro Support return of multiple values for a single LDAP lookup. The 253864562Sgshapiro values to be returned should be in a comma separated string. 253964562Sgshapiro For example, `-v "email,emailother"'. Patch from 254064562Sgshapiro Curtis W. Hillegas of Princeton University. 254164562Sgshapiro Allow the use of LDAP for alias maps. 254264562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 254364562Sgshapiro attributes found in the match will be returned. 254464562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 254564562Sgshapiro breaking up a single entry into multiple entries. This is 254664562Sgshapiro needed for LDAP alias file specifications to allow for 254764562Sgshapiro comma separated key and value strings. 254864562Sgshapiro Keep connections to LDAP server open instead of opening and closing 254964562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 255064562Sgshapiro connections such that multiple maps which use the same 255164562Sgshapiro host, port, bind DN, and authentication will only result in 255264562Sgshapiro a single connection to that host. 255364562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 255464562Sgshapiro Be more careful about checking for errors and freeing memory on 255564562Sgshapiro LDAP lookups. 255664562Sgshapiro Use asynchronous LDAP searches to save memory and network 255764562Sgshapiro resources. 255864562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 255964562Sgshapiro Increase portability to the Netscape LDAP libraries. 256064562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 256164562Sgshapiro replaced with the literal contents of the map lookup key -- 256264562Sgshapiro note that this means a lookup can be done using the LDAP 256364562Sgshapiro special characters. The new '%0' token can be used instead 256464562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 256564562Sgshapiro For example, if the LDAP map specification contains '-k 256664562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 256764562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 256864562Sgshapiro user attribute. Instead, if the LDAP map specification 256964562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 257064562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 257164562Sgshapiro with the name "*". 257264562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 257364562Sgshapiro more than one is returned, it is equivalent to no records 257464562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 257564562Sgshapiro alias dereference option; "-Z size" limits the number of 257664562Sgshapiro matches to return. 257764562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 257864562Sgshapiro LDAP maps. The value should only contain LDAP specific 257964562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 258064562Sgshapiro settings will be used for all LDAP maps unless they are 258164562Sgshapiro specified in the individual map specification ('K' 258264562Sgshapiro command). This option should be set before any LDAP maps 258364562Sgshapiro are defined. 258464562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 258564562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 258664562Sgshapiro Tech. 258764562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 258864562Sgshapiro particular, class entries get much smaller, which can be 258964562Sgshapiro important if you have large classes. 259064562Sgshapiro On network-related temporary failures, record the hostname which 259164562Sgshapiro gave error in the queued status message. Requested by 259264562Sgshapiro Ulrich Windl of the Universitat Regensburg. 259364562Sgshapiro Add new F=% mailer flag to allow for a store and forward 259464562Sgshapiro configuration. Mailers which have this flag will not attempt 259571345Sgshapiro delivery on initial receipt of a message or on queue runs 259664562Sgshapiro unless the queued message is selected using one of the 259764562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 259864562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 259964562Sgshapiro New option ControlSocketName which, when set, creates a daemon 260064562Sgshapiro control socket. This socket allows an external program to 260164562Sgshapiro control and query status from the running sendmail daemon 260264562Sgshapiro via a named socket, similar to the ctlinnd interface to the 260364562Sgshapiro INN news server. Access to this interface is controlled by 260464562Sgshapiro the UNIX file permissions on the named socket on most UNIX 260564562Sgshapiro systems (see sendmail/README for more information). An 260664562Sgshapiro example control program is provided as contrib/smcontrol.pl. 260764562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 260864562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 260964562Sgshapiro number of processors online on the system (if that can be 261064562Sgshapiro determined). For single processor machines, this change 261164562Sgshapiro has no effect. 261264562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 261364562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 261464562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 261564562Sgshapiro Motonori Nakamura of Kyoto University. 261664562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 261764562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 261864562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 261964562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 262064562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 262164562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 262264562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 262364562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 262464562Sgshapiro connection-based denial of service attacks. 262564562Sgshapiro Log basic information about authenticated connections at LogLevel 262664562Sgshapiro 10 or higher. 262764562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 262864562Sgshapiro information (from= syslog line). 262964562Sgshapiro Log the DSN code for each recipient if one is available as a new 263064562Sgshapiro equate (dsn=). 263164562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 263264562Sgshapiro New "ph" map for performing ph queries in rulesets.

Problem noted by Kari Hurtta of the 263864562Sgshapiro Finnish Meteorological Institute. 263964562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 264064562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 264164562Sgshapiro When a forward file points to an alias which runs a program, run 264264562Sgshapiro the program as the default user and the default group, not 264364562Sgshapiro the forward file user. This change also assures the 264464562Sgshapiro :include: directives in aliases are also processed using 264564562Sgshapiro the default user and group. Problem noted by Sergiu 264664562Sgshapiro Popovici of DNT Romania. 264764562Sgshapiro Prevent attempts to save a dead.letter file for a user with 264864562Sgshapiro no home directory (/no/such/directory). Problem noted by 264964562Sgshapiro Michael Brown of Finnigan FT/MS. 265064562Sgshapiro Include message delay and number of tries when logging that a 265164562Sgshapiro message has been completely delivered (LogLevel of 10 or 265264562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 265364562Sgshapiro Log the sender of a message even if none of the recipients were 265464562Sgshapiro accepted. If some of the recipients were rejected, it is 265564562Sgshapiro helpful to know the sender of the message. 265664562Sgshapiro Check the root directory (/) when checking a path for safety. 265764562Sgshapiro Problem noted by John Beck of Sun Microsystems. 265864562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 265964562Sgshapiro interactive and delivering to an alias which resolves to 266064562Sgshapiro multiple files. 266164562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 266264562Sgshapiro greater (see below); the help function doesn't print the 266364562Sgshapiro version of sendmail any longer, instead it is placed in 266464562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 266564562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 266664562Sgshapiro skipped and a version line (#vers) is introduced. The 266764562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 266864562Sgshapiro version is found, a warning is logged. The '#vers' 266964562Sgshapiro directive should be placed at the top of the help file. 267064562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 267164562Sgshapiro disk succeeded. Suggested by Nick Christenson. 267264562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 267364562Sgshapiro length before the attempt. 267464562Sgshapiro If a forward points to a filename for delivery, change to the 267564562Sgshapiro user's uid before checking permissions on the file. This 267664562Sgshapiro allows delivery to files on NFS mounted directories where 267764562Sgshapiro root is remapped to nobody. Problem noted by Harald 267864562Sgshapiro Daeubler of Universitaet Ulm. 267964562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 268064562Sgshapiro host status files, not all files. 268164562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 268264562Sgshapiro in the queue file for the message and set when delivery 268364562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 268464562Sgshapiro Wonderworks Inc. 268564562Sgshapiro Add support for storing information between rulesets using the new 268664562Sgshapiro macro map class. This can be used to store information 268764562Sgshapiro between queue runs as well using $={persistentMacros}. 268864562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 268964562Sgshapiro of Hannover. 269064562Sgshapiro New map class arith to allow for computations in rules. The 269164562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 269264562Sgshapiro as key. The two operands are specified as arguments; the 269364562Sgshapiro lookup returns the result of the computation. For example, 269464562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 269564562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 269664562Sgshapiro Add new syntax for header declarations which decide whether to 269764562Sgshapiro include the header based on a macro rather than a mailer 269864562Sgshapiro flag: 269964562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 270064562Sgshapiro This should be used along with $={persistentMacros}. 270164562Sgshapiro It can be used for adding headers to a message based on 270264562Sgshapiro the results of check_* and header check rulesets. 270364562Sgshapiro Allow new named config file rule check_eoh which is called after 270464562Sgshapiro all of the headers have been collected. The input to the 270564562Sgshapiro ruleset the number of headers and the size of all of the 270664562Sgshapiro headers in bytes separated by $|. This ruleset along with 270764562Sgshapiro the macro storage map can be used to correlate information 270864562Sgshapiro gathered between headers and to check for missing headers. 270964562Sgshapiro See cf/README or doc/op/op.ps for an example. 271064562Sgshapiro Change the default for the MeToo option to True to correspond 271164562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 271264562Sgshapiro option is deprecated and will be removed from a future 271364562Sgshapiro version. 271464562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 271564562Sgshapiro Change the sendmail binary default for SuperSafe to True. 271664562Sgshapiro Display ruleset names in debug and address test mode output 271764562Sgshapiro if referencing a named ruleset. 271864562Sgshapiro New mailer equate m= which will limit the number of messages 271964562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 272064562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 272164562Sgshapiro using it to sort. Now all the same domains are really run 272264562Sgshapiro through the queue together. If they have the same MX host, 272364562Sgshapiro then they will have a much better opportunity to use the 272464562Sgshapiro connection cache if available. This should be a reasonable 272564562Sgshapiro performance improvement. Patch from Randall Winchester of 272664562Sgshapiro the University of Maryland. 272764562Sgshapiro If a message is rejected by a header check ruleset, log who would 272864562Sgshapiro have received the message if it had not been rejected. 272964562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 273064562Sgshapiro queue immediately. No delivery attempt is made. 273164562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 273264562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 273364562Sgshapiro COMMANDS). 273464562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 273564562Sgshapiro but for outgoing connections. 273664562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 273764562Sgshapiro error messages and logging) and Modifiers, i.e. 273864562Sgshapiro a require authentication 273964562Sgshapiro b bind to interface through which mail has 274064562Sgshapiro been received 274164562Sgshapiro c perform hostname canonification 274264562Sgshapiro f require fully qualified hostname 274364562Sgshapiro h use name of interface for outgoing HELO 274464562Sgshapiro command 274564562Sgshapiro C don't perform hostname canonification 274664562Sgshapiro E disallow ETRN (see RFC 2476) 274764562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 274864562Sgshapiro h use name of interface for HELO command 274964562Sgshapiro The version number for queue files (qf) has been incremented to 4. 275064562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 275164562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 275264562Sgshapiro Institutes of Health. 275364562Sgshapiro If a mailer dies, print the status in decimal instead of octal 275464562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 275564562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 275664562Sgshapiro Move message priority from sender to recipient logging. Suggested by 275764562Sgshapiro Ulrich Windl of the Universitat Regensburg. 275864562Sgshapiro Add support for Berkeley DB 3.X. 275964562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 276064562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 276164562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 276264562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 276364562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 276464562Sgshapiro sub-options is set on the command line. Problem noted by 276564562Sgshapiro Graeme Hewson of Oracle. 276664562Sgshapiro Randomize equal preference MX records each time delivery is 276764562Sgshapiro attempted via a new connection to a host instead of once per 276864562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 276964562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 277064562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 277164562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 277264562Sgshapiro to hosts which have dynamically assigned names. 277364562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 277464562Sgshapiro the bounce for the same reason. If the body is not 8-bit 277564562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 277664562Sgshapiro not be included in the bounce. Problem noted by Valdis 277764562Sgshapiro Kletnieks of Virginia Tech. 277864562Sgshapiro The timeout for sending a message via SMTP has been changed from 277964562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 278064562Sgshapiro simply checks for progress on sending data every 5 minutes. 278164562Sgshapiro This will detect the inability to send information quicker 278264562Sgshapiro and reduce the number of processes simply waiting to 278364562Sgshapiro timeout. 278464562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 278564562Sgshapiro interface address structure when loading the system network 278664562Sgshapiro interface addresses.

Suggested by many. 290364562Sgshapiro Persistent host status data is not reloaded disk when current data 290464562Sgshapiro is available in the in-memory cache. Problem noted by Per 290564562Sgshapiro Hedeland of Ericsson. 290664562Sgshapiro mailq displays unprintable characters in addresses as their octal 290764562Sgshapiro representation and a leading backslash. This avoids problems 290864562Sgshapiro with "unprintable" characters. Problem noted by Michal 290964562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 291064562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 291164562Sgshapiro one character past the limit. This would cause subsequent 291264562Sgshapiro hops to break the line again. The '!' is now placed in 291364562Sgshapiro the last column of the limit if the line needs to be broken. 291464562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 291564562Sgshapiro from Per Hedeland of Ericsson. 291664562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 291764562Sgshapiro resolver will fall back to TCP. However, some 291864562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 291964562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 292064562Sgshapiro don't fail on ANY queries. 292164562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 292264562Sgshapiro address, do not send an empty postmaster notification DSN 292364562Sgshapiro to the postmaster.

Suggested by Joe Pruett 310364562Sgshapiro of Q7 Enterprises. 310464562Sgshapiro CONFIG: MASQUERADE_EXCEPTION() defines hosts/subdomains which 310564562Sgshapiro will not be masqueraded. Proposed by Arne Wichmann 310664562Sgshapiro of MPI Saarbruecken, Griff Miller of PGS Tensor, 310764562Sgshapiro Jayme Cox of Broderbund Software Inc. 310864562Sgshapiro CONFIG: A list of exceptions for FEATURE(`nocanonify') can be 310964562Sgshapiro specified by CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE, 311064562Sgshapiro i.e., a list of domains which are passed to $[ ... $] 311164562Sgshapiro for canonification. Based on an idea from Neil Rickert 311264562Sgshapiro of Northern Illinois University. 311364562Sgshapiro CONFIG: If `canonify_hosts' is specified as parameter for 311464562Sgshapiro FEATURE(`nocanonify') then addresses which have only 311564562Sgshapiro a hostname, e.g., <user@host>, will be canonified. 311664562Sgshapiro CONFIG: If FEATURE(`nocanonify') is turned on, a trailing dot is 311764562Sgshapiro nevertheless added to addresses with more than one component 311864562Sgshapiro in it. 311964562Sgshapiro CONFIG: Canonification is no longer attempted for any host or domain 312064562Sgshapiro in class 'P' ($=P). 312164562Sgshapiro CONFIG: New class for matching virtusertable entries $={VirtHost} that 312264562Sgshapiro can be populated by VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE. 312364562Sgshapiro FEATURE(`virtuser_entire_domain') can be used to apply this 312464562Sgshapiro class also to entire subdomains. Hosts in this class are 312564562Sgshapiro treated as canonical in SCanonify2, i.e., a trailing dot 312664562Sgshapiro is added. 312764562Sgshapiro CONFIG: If VIRTUSER_DOMAIN() or VIRTUSER_DOMAIN_FILE() are used, 312864562Sgshapiro include $={VirtHost} in $=R (hosts allowed to relay). 312964562Sgshapiro CONFIG: FEATURE(`generics_entire_domain') can be used to apply the 313064562Sgshapiro genericstable also to subdomains of $=G. 313164562Sgshapiro CONFIG: Pass "+detail" as %2 for virtusertable lookups. 313264562Sgshapiro Patch from Noam Freedman from University of Chicago. 313364562Sgshapiro CONFIG: Pass "+detail" as %1 for genericstable lookups. Suggested 313464562Sgshapiro by Raymond S Brand of rsbx.net. 313564562Sgshapiro CONFIG: Allow @domain in genericstable to override masquerading. 313664562Sgshapiro Suggested by Owen Duffy from Owen Duffy & Associates. 313764562Sgshapiro CONFIG: LOCAL_DOMAIN() adds entries to class w. Suggested by Steve 313864562Sgshapiro Hubert of University of Washington. 313964562Sgshapiro CONFIG: OSTYPE(`gnuhurd') has been replaced by OSTYPE(`gnu') as 314064562Sgshapiro GNU is now the canonical system name.

Prindeville of Enteka Enterprise Technology 314864562Sgshapiro Services. 314964562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 315064562Sgshapiro names. Problem noted by Randall Winchester of Swales 315164562Sgshapiro Aerospace. 315264562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 315364562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 315464562Sgshapiro University and Brian Candler. 315564562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 315664562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 315764562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 315864562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 315964562Sgshapiro Institute. 316064562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 316164562Sgshapiro i.e., to set, add, or delete flags. 316264562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 316364562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 316464562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 316564562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 316664562Sgshapiro after check_rcpt and allows for exceptions from the checks. 316764562Sgshapiro CONFIG: Map declarations have been moved into their associated 316864562Sgshapiro feature files to allow greater flexibility in use of 316964562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 317064562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 317164562Sgshapiro line string for the local mailer. Requested by Il Oh of 317264562Sgshapiro Willamette Industries, Inc. 317364562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 317464562Sgshapiro converted to <user@d> 317564562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 317664562Sgshapiro Sun's older, broken configuration files. 317764562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 317864562Sgshapiro normal configuration, allowing anti-spam checks to be 317964562Sgshapiro performed. 318064562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 318164562Sgshapiro ${client_name} can't be resolved just temporarily. 318264562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 318364562Sgshapiro Institute. 318464562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 318564562Sgshapiro be accessed by their numbers). 318664562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 318764562Sgshapiro which describes whether to disallow "!" in the local part 318864562Sgshapiro of an address. 318964562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 319064562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 319164562Sgshapiro set. If the ruleset returns a mailer, the appropriate 319264562Sgshapiro action is taken, otherwise the returned tokens are ignored. 319364562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 319464562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 319564562Sgshapiro The latter is kept around for backward compatibility. 319664562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 319764562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 319864562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 319964562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 320064562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 320164562Sgshapiro Institute. 320264562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 320364562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 320464562Sgshapiro arguments overriding the mailer program, arguments, and 320564562Sgshapiro mailer definition flags. This makes it possible to use 320664562Sgshapiro other programs such as maildrop for local delivery. 320764562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 320864562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 320964562Sgshapiro Patch from Richard A. Nelson of IBM. 321064562Sgshapiro CONFIG: Add SMTP Authentication information to Received: header 321164562Sgshapiro default value (confRECEIVED_HEADER). 321264562Sgshapiro CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a 321364562Sgshapiro local mailer. Problem noted by Per Hedeland of Ericsson. 321464562Sgshapiro CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the 321564562Sgshapiro University of California at Berkeley. 321664562Sgshapiro CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of 321764562Sgshapiro Illinois at Urbana-Champaign. 321864562Sgshapiro CONTRIB: etrn.pl now recognizes bogus host names. Patch from 321964562Sgshapiro Bruce Barnett of GE's R&D Lab. 322064562Sgshapiro CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle 322164562Sgshapiro Corporation UK. 322264562Sgshapiro CONTRIB: Added qtool.pl to assist in managing the queues. 322364562Sgshapiro DEVTOOLS: Prevent user environment variables from interfering with 322464562Sgshapiro the Build scripts. Problem noted by Ezequiel H. Panepucci of 322564562Sgshapiro Yale University. 322664562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 322764562Sgshapiro be used for building. 322864562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 322964562Sgshapiro used for a fresh build. 323064562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 323164562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 323264562Sgshapiro ranlib. 323364562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 323464562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 323564562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 323664562Sgshapiro building of the man pages when defined. Suggested by Bryan 323764562Sgshapiro Costales. 323864562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 323964562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 324064562Sgshapiro installation of the sendmail helpfile and statistics file 324164562Sgshapiro respectively. Suggested by Bryan Costales. 324264562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 324364562Sgshapiro of Siemens Business Services. 324464562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 324564562Sgshapiro stdio library. The new buffered file I/O depends on the 324664562Sgshapiro Torek stdio library. This option can be either portable or 324764562Sgshapiro torek. 324864562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 324964562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 325064562Sgshapiro They should contain the C source files for the object files 325164562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 325264562Sgshapiro will be passed to the 'make depend' stage of compilation. 325364562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 325464562Sgshapiro in the sendmail distribution. Each has the form 325564562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 325664562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 325764562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 325864562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 325964562Sgshapiro building the distribution, but documentation on the changes 326064562Sgshapiro are in devtools/README. 326164562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 326264562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 326364562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 326464562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 326564562Sgshapiro new variable which identifies the root of the source 326664562Sgshapiro directories for all of the programs in the distribution. 326764562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 326864562Sgshapiro time. They can both still be overridden by setting the m4 326964562Sgshapiro macro. 327064562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 327164562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 327264562Sgshapiro build configurations, and places objects in obj.prefix.*/. 327364562Sgshapiro Complains as 'Build -f file' does for existing object 327464562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 327564562Sgshapiro Corporation. 327664562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 327764562Sgshapiro manual pages in the directory tree specified by 327864562Sgshapiro confMANROOTMAN. 327964562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 328064562Sgshapiro preformatted pages from the distribution. The new variable 328164562Sgshapiro confCOPY specifies the copying program. 328264562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 328364562Sgshapiro question. Suggested by Terry Lambert of Whistle 328464562Sgshapiro Communications. 328564562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 328664562Sgshapiro of the installed statistics and help files, respectively. 328764562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 328864562Sgshapiro operating system identity. Problem noted by Erik 328964562Sgshapiro Wachtenheim of Dartmouth College. 329064562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 329164562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 329264562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 329364562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 329464562Sgshapiro how to strip binaries. These are used by the new 329564562Sgshapiro install-strip target. 329664562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 329764562Sgshapiro the others (if it exists). 329864562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 329964562Sgshapiro then the default ones. 330090792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 330164562Sgshapiro as local delivery agent without LMTP mode, use 330264562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 330364562Sgshapiro to set the S flag. 330464562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 330564562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 330664562Sgshapiro Northern Illinois University. 330764562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 330864562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 330964562Sgshapiro the Finnish Meteorological Institute. 331064562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 331164562Sgshapiro MAILLOCK when compiling. Also requires linking with 331264562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 331364562Sgshapiro University. 331464562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 331564562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 331664562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 331764562Sgshapiro University. 331864562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 331964562Sgshapiro structure to the beginning of the program. This ensures that 332064562Sgshapiro the getservbyname() is done before any seteuid to a possibly 332164562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 332264562Sgshapiro on a Solaris system, this avoids syslog messages such as, 332364562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 332464562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 332564562Sgshapiro University. 332664562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 332764562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 332864562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 332964562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 333064562Sgshapiro characters (in LMTP mode), mail.local split the incoming 333164562Sgshapiro line up into 2046-character output lines (excluding the 333264562Sgshapiro newline). If an input line was 2047 characters long 333364562Sgshapiro (excluding CR-LF) and the last character was a '.', 333464562Sgshapiro mail.local saw it as the end of input, transfered it to the 333564562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 333664562Sgshapiro If the message was much longer, both sendmail and 333764562Sgshapiro mail.local would deadlock waiting for each other to read 333864562Sgshapiro what they have written. Problem noted by Peter Jeremy of 333964562Sgshapiro Alcatel Australia Limited. 334064562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 334164562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 334264562Sgshapiro Neil Rickert of Northern Illinois University. 334364562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 334464562Sgshapiro timeout to avoid starvation. 334564562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 334664562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 334764562Sgshapiro Infinite Monkeys & Co. 334864562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 334964562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 335064562Sgshapiro printed in a machine readable fashion and the stats file 335164562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 335264562Sgshapiro of Maryland. 335364562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 335464562Sgshapiro generated maps to the TrustedUser as specified in the 335564562Sgshapiro sendmail configuration file. 335664562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 335764562Sgshapiro configuration file to use for finding the TrustedUser 335864562Sgshapiro option. 335964562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 336064562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 336164562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 336264562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 336364562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 336464562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 336564562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 336664562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 336764562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 336864562Sgshapiro Corporation UK. 336964562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 337064562Sgshapiro (e.g., sendmail would not drop root privileges if the 337164562Sgshapiro option was specified on the command line). Problem noted 337264562Sgshapiro by Todd C. Miller of Courtesan Consulting. 337364562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 337464562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 337564562Sgshapiro Institute for Global Communications. 337664562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 337764562Sgshapiro alias file(s) if the -f option is not used. Patch from 337864562Sgshapiro John Beck of Sun Microsystems. 337964562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 338064562Sgshapiro configuration file to use for finding alias file(s). Patch 338164562Sgshapiro from John Beck of Sun Microsystems. 338264562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 338364562Sgshapiro lists using || and &&.

Sites 383038032Speter which need the ability to override security can use the 383138032Speter DontBlameSendmail option. See the README file for more 383238032Speter information. 383338032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 383438032Speter if maps or alias files are in world writable directories. 383538032Speter This fixes the change added to 8.8.6 to prevent links in these 383638032Speter world writable directories. 383738032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 383838032Speter it is in a world writable directory. 383938032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 384038032Speter tty it may be able to push bytes back to the senders input. 384138032Speter Unfortunately this breaks -v mode.

After this number is reached, sendmail 390138032Speter starts returning "452 Too many recipients" to all RCPT 390238032Speter commands. This can be used to limit the number of recipients 390338032Speter per envelope (in particular, to discourage use of the server 390438032Speter for spamming). Note: a better approach is to restrict 390538032Speter relaying entirely. 390638032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 390738032Speter to ldapx map and added timeout for ldap_open call to 390838032Speter avoid hanging sendmail in the event of hung LDAP servers. 390938032Speter Patch from Booker Bense of Stanford University. 391038032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 392938032Speter of Procter & Gamble. 393038032Speter The LDAP map -s flag was not properly parsed and the error message 393164562Sgshapiro given included the remainder of the arguments instead of 393238032Speter solely the argument in error. Problem noted by Aidan Nichol 393338032Speter of Procter & Gamble. 393438032Speter New DontBlameSendmail option. This option allows administrators to 393538032Speter bypass some of sendmail's file security checks at the expense 393638032Speter of system security.

In particular, if you 397238032Speter have lots of virtual interfaces, this option will speed up 397338032Speter startup.

If they differ or if the PTR lookup 398338032Speter fails, &{client_name} will contain the IP address 398464562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 398538032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 398638032Speter (i.e, it is like -ax for the temporary failure case, in 398738032Speter contrast to the success case). 398838032Speter New syntax to do limited checking of header syntax. A config line 398938032Speter of the form: 399038032Speter HHeader: $>Ruleset 399138032Speter causes the indicated Ruleset to be invoked on the Header 399238032Speter when read. This ruleset works like the check_* rulesets -- 399338032Speter that is, it can reject mail on the basis of the contents. 399438032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 399538032Speter from hiding their connection information in Received: 399638032Speter headers. 399738032Speter When SingleThreadDelivery is active, deliveries to locked hosts 399838032Speter are skipped. This will cause the delivering process to 399938032Speter try the next MX host or queue the message if no other MX 400038032Speter hosts are available. Suggested by Alexander Litvin. 400138032Speter The [FILE] mailer type now delivers to the file specified in the 400238032Speter A= equate of the mailer definition instead of $u. It also 400338032Speter obeys all of the F= mailer flags such as the MIME 400438032Speter 7/8 bit conversion flags. This is useful for defining 400538032Speter a mailer which delivers to the same file regardless of the 400664562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 400738032Speter Do not assume the identity of a remote connection is root@localhost 400838032Speter if the remote connection closes the socket before the 400938032Speter remote identity can be queried. 401038032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 401138032Speter Some mailers, including procmail, require that the real 401238032Speter uid is left unchanged by sendmail. Problem noted by Per 401338032Speter Hedeland of Ericsson. 401438032Speter No longer is the src/obj*/Makefile selected from a large list -- it 401538032Speter is now generated using the information in BuildTools/OS/ -- 401638032Speter some of the details are determined dynamically via 401738032Speter BuildTools/bin/configure.sh. 401838032Speter The other programs in the sendmail distribution -- mail.local, 401938032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 402038032Speter the new Build method which creates an operating system 402138032Speter specific Makefile using the information in BuildTools. 402238032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 402338032Speter a failure on one message won't affect future messages to the 402438032Speter same host). This is necessary if the remote host sends 402538032Speter a 451 error if the domain of the sender does not resolve 402638032Speter as is common in anti-spam configurations. Problem noted 402738032Speter by Mitchell Blank Jr of Exec-PC. 402838032Speter New "discard" mailer for check_* rulesets and header checking 402938032Speter rulesets. If one of the above rulesets resolves to the 403038032Speter $#discard mailer, the commands will be accepted but the 403138032Speter message will be completely discarded after it is accepting. 403238032Speter This means that even if only one of the recipients 403338032Speter resolves to the $#discard mailer, none of the recipients 403438032Speter will receive the mail. Suggested by Brian Kantor. 403538032Speter All but the last cloned envelope of a split envelope were queued 403638032Speter instead of being delivered.

Problem noted by 407038032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 407138032Speter Include a magic number and version in the StatusFile for the 407238032Speter mailstats command. 407338032Speter Record the number of rejected and discarded messages in the 407438032Speter StatusFile for display by the mailstats command. Patch 407538032Speter from Randall Winchester of the University of Maryland. 407638032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 407738032Speter user portion as IDENT:username@site instead of 407838032Speter username@site to differentiate the two. Suggested by 407938032Speter Kari Hurtta of the Finnish Meteorological Institute. 408038032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 408138032Speter Ericsson. 408238032Speter Change persistent host status filename substitution so '/' is 408338032Speter replaced by ':' instead of '|' to avoid clashes. Also 408438032Speter avoid clashes with hostnames with leading dots. Fix from 408538032Speter Mitchell Blank Jr. of Exec-PC. 408638032Speter If the system lock table is full, only attempt to create a new 408738032Speter queue entry five times before giving up. Previously, it 408838032Speter was attempted indefinitely which could cause the partition 408938032Speter to run out of inodes. Problem noted by Suzie Weigand of 409038032Speter Stratus Computer, Inc. 409138032Speter In verbose mode, warn if the sendmail.cf version is less than the 409238032Speter currently supported version. 409338032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 409438032Speter from Randall S. Winchester of the University of Maryland. 409538032Speter Properly quote a full name passed via the -F command line option, 409638032Speter the Full-Name: header, or the NAME environment variable if 409738032Speter it contains characters which must be quoted. Problem noted 409838032Speter by Kari Hurtta of the Finnish Meteorological Institute. 409938032Speter Avoid possible race condition that unlocked a mail job before 410038032Speter releasing the transcript file on systems that use flock(2). 410138032Speter In some cases, this might result in a "Transcript Unavailable" 410238032Speter message in error bounces. 410338032Speter Accept SMTP replies which contain only a reply code and no 410438032Speter accompanying text. Problem noted by Fernando Fraticelli of 410538032Speter Digital Equipment Corporation. 410638032Speter Portability: 410738032Speter AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura 410838032Speter of Kyoto University. 410938032Speter AIX 4.2 requires <userpw.h> before <usersec.h>.

From Guillermo Freige of 413038032Speter Gobernacion de la Pcia de Buenos Aires and Paul 413138032Speter Fischer of BTG, Inc. 413238032Speter SunOS 4.X does not include memmove(). Patch from 413338032Speter Per Hedeland of Ericsson. 413438032Speter SunOS 5.7 includes getloadavg() function for determining 413538032Speter load average. Patch from John Beck of Sun 413638032Speter Microsystems. 413738032Speter CONFIG: Increment version number of config file. 413838032Speter CONFIG: add DATABASE_MAP_TYPE to set the default type of database 413938032Speter map for the various maps. The default is hash. Patch from 414038032Speter Robert Harker of Harker Systems. 414138032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 414238032Speter directory for certain programs. 414338032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 414438032Speter local mail delivery. By the default, /usr/libexec/mail.local 414538032Speter is used. This is expected to be the mail.local shipped 414638032Speter with 8.9 which is LMTP capable. The path is based on the 414738032Speter new confEBINDIR m4 variable. 414838032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 414938032Speter FEATURE(smrsh). Note that this changes the default from 415038032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 415138032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 415238032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 415338032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 415438032Speter the user to setup different .forward files for 415538032Speter user+detail addressing. 415638032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 415738032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 415838032Speter DontProbeInterfaces, and DontBlameSendmail options. 415938032Speter CONFIG: by default do not allow relaying (that is, accepting mail 416038032Speter from outside your domain and sending it to another host 416138032Speter outside your domain). 416238032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 416338032Speter any site to any site. 416438032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 416538032Speter domain as defined by the 'm' class ($=m) to relay. 416638032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 416738032Speter the MX records of the host portion of an incoming recipient. 416838032Speter CONFIG: new FEATURE(access_db) which turns on the access database 416977349Sgshapiro feature. This database gives you the ability to allow 417038032Speter or refuse to accept mail from specified domains for 417138032Speter administrative reasons. By default, names that are listed 417238032Speter as "OK" in the access db are domain names, not host names. 417338032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 417438032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 417538032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 417638032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 417738032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 417838032Speter of FEATURE(access_db) and class 'R' to lookup individual 417938032Speter host names only. 418038032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 418138032Speter using % addressing is used, e.g. user%site@othersite, 418238032Speter and othersite is in class 'R', the check_rcpt ruleset 418338032Speter will strip @othersite and recheck user@site for relaying. 418438032Speter This feature changes that behavior. It should not be 418538032Speter needed for most installations. 418638032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 418738032Speter domain portion of the mail sender is a local host. This 418838032Speter should only be used if absolutely necessary as it opens 418938032Speter a window for spammers. Patch from Randall S. Winchester of 419038032Speter the University of Maryland. 419138032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 419238032Speter block incoming mail destined for certain recipient 419338032Speter usernames, hostnames, or addresses. 419438032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 419538032Speter refused if the host part of the argument to MAIL FROM: cannot 419638032Speter be located in the host name service (e.g., DNS). 419738032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 419838032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 419938032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 420038032Speter MAIL FROM: senders which do not include a domain. 420138032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 420238032Speter Realtime Blackhole List. You can specify the RBL name 420338032Speter server to contact by specifying it as an optional argument. 420438032Speter The default is rbl.maps.vix.com. For details, see 420538032Speter http://maps.vix.com/rbl/. 420638032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 420738032Speter Local_check_rcpt from check_relay, check_mail, and 420838032Speter check_rcpt. Users with local rulesets should place the 420938032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 421038032Speter returns $#OK, the message is accepted. If the ruleset 421138032Speter returns a mailer, the appropriate action is taken, else 421238032Speter the return of the ruleset is ignored. 421338032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 421438032Speter default to support file, :include:, and program deliveries. 421538032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 421638032Speter pick the proper default value. See the SECURITY note 421738032Speter above for more information. 421838032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 421938032Speter no-op. Patch from Kari Hurtta of the Finnish 422038032Speter Meteorological Institute. 422138032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 422238032Speter daemon since DEC's /bin/mail will drop the envelope 422338032Speter sender if run as mailnull. See the Digital UNIX section 422438032Speter of src/README for more information. Problem noted by 422538032Speter Kari Hurtta of the Finnish Meteorological Institute. 422638032Speter CONFIG: .cf files are now stored in the same directory with the 422738032Speter .mc files instead of in the obj directory. 422864562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 422938032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 423038032Speter setting SingleLineFromHeader, AllowBogusHELO, and 423138032Speter MustQuoteChars respectively. 423238032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout. This 423338032Speter SMTP-like protocol allows detailed reporting of delivery 423438032Speter status on a per-user basis. Code donated by John Myers of 423538032Speter CMU (now of Netscape). 423638032Speter MAIL.LOCAL: HP-UX support from Randall S. Winchester of the 423764562Sgshapiro University of Maryland. NOTE: mail.local is not 423838032Speter compatible with the stock HP-UX mail format. Be sure to 423938032Speter read mail.local/README. 424038032Speter MAIL.LOCAL: Prevent other mail delivery agents from stealing a 424138032Speter mailbox lock. Patch from Randall S.

Problem noted by Greg Nichols of Wind 436538032Speter River Systems. 436638032Speter If SingleThreadDelivery was enabled and the remote server returned a 436738032Speter protocol error on the DATA command, the connection would be 436838032Speter closed but the persistent host status file would not be 436938032Speter unlocked so other sendmail processes could not deliver to 437038032Speter that host. Problem noted by Peter Wemm of DIALix. 437138032Speter If queueing up a message due to an expensive mailer, don't increment 437238032Speter the number of delivery attempts or set the last delivery 437338032Speter attempt time so the message will be delivered on the next 437438032Speter queue run regardless of MinQueueAge. Problem noted by 437538032Speter Brian J. Coan of the Institute for Global Communications. 437638032Speter Authentication warnings of "Processed from queue _directory_" and 437738032Speter "Processed by _username_ with -C _filename_" would be logged 437838032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 437938032Speter of the Finnish Meteorological Institute. 438038032Speter Use a better heuristic for detecting GDBM. 438138032Speter Log null connections on dropped connections. Problem noted by 438238032Speter Jon Lewis of Florida Digital Turnpike. 438338032Speter If class dbm maps are rebuilt, sendmail will now detect this and 438438032Speter reopen the map. Previously, they could give stale 438538032Speter results during a single message processing (but would 438638032Speter recover when the next message was received). Fix from 438738032Speter Joe Pruett of Q7 Enterprises. 438838032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 438938032Speter requests. Problem noted by Kari E.

Problem noted by Kari E. Hurtta of the 439438032Speter Finnish Meteorological Institute. 439538032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 439638032Speter sendmail via a UNIX pipe. This will allow rulesets using 439738032Speter $&{client_name} to process without sending the string through 439838032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 439938032Speter A combination of deferred delivery mode, a double bounce situation, 440038032Speter and the inability to save a bounce message to 440138032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 440238032Speter to postmaster but not remove the offending envelope from the 440338032Speter queue causing it to create a new bounce message each time the 440438032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 440538032Speter Associates. 440638032Speter Remove newlines from hostname information returned via DNS. There are 440738032Speter no known security implications of newlines in hostnames as 440838032Speter sendmail filters newlines in all vital areas; however, this 440938032Speter could cause confusing error messages. 441038032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 441138032Speter rejected if any of the specified addresses were bad. This 441238032Speter behavior was modified to only reject the bad addresses and not 441338032Speter the entire message.

Based on a patch from Steve Schweinhart of 454038032Speter Results Computing. 454138032Speter If a qf file was found in a mail queue directory that had a problem 454238032Speter (wrong ownership, bad format, etc.) and the file name was 454338032Speter exactly MAXQFNAME bytes long, then instead of being tried 454438032Speter once, it would be tried on every queue run. Problem noted 454538032Speter by Bryan Costales of Mercury Mail. 454638032Speter If the system supports an st_gen field in the status structure, 454738032Speter include it when reporting that a file has changed after open. 454838032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 454938032Speter This out to be checked as well as reported, since it is 455038032Speter theoretically possible for an attacker to remove a file after 455138032Speter it is opened and replace it with another file that has the 455238032Speter same i-number, but some filesystems (notably AFS) return 455338032Speter garbage in this field, and hence always look like the file 455438032Speter has changed. As a practical matter this is not a security 455538032Speter problem, since the files can be neither hard nor soft links, 455638032Speter and on no filesystem (that I am aware of) is it possible to 455738032Speter have two files on the same filesystem with the same i-number 455838032Speter simultaneously. 455938032Speter Delete the root Makefile from the distribution -- it is only for 456038032Speter use internally, and does not work at customer sites. 456138032Speter Fix botch that caused the second MAIL FROM: command in a single 456238032Speter transaction to clear the entire transaction.

This makes it possible to create a root 464838032Speter owned file in an arbitrary directory by inserting the symlink 464938032Speter into a writable directory after the initial lstat(2) check 465038032Speter determined that the file did not exist. The only verified 465138032Speter example of a system having these odd semantics for O_EXCL 465238032Speter and symbolic links was HP-UX prior to version 9.07. Most 465338032Speter systems do not have the problem, since a exclusive create 465438032Speter of a file disallows symbolic links. Systems that have been 465538032Speter verified to NOT have the problem include AIX 3.x, *BSD, 465638032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 465738032Speter and Ultrix. This is a potential exposure on systems that 465838032Speter have this bug and which do not have a MAILER-DAEMON alias 465938032Speter pointing at a legitimate account, since this will cause old 466038032Speter mail to be dropped in /var/tmp/dead.letter. 466138032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 466238032Speter if maps or alias files are in world writable directories. 466338032Speter If your system has alias maps in writable directories, it 466438032Speter is potentially possible for an attacker to replace the .db 466538032Speter (or .dir and .pag) files by symbolic links pointing at 466638032Speter another database; this can be used either to expose 466738032Speter information (e.g., by pointing an alias file at /etc/spwd.db 466838032Speter and probing for accounts), or as a denial-of-service attack 466938032Speter (by trashing the password database). The fix disallows 467038032Speter symbolic links entirely when rebuilding alias files or on 467138032Speter maps that are in writable directories, and always warns on 467238032Speter writable directories; 8.9 will probably consider writable 467338032Speter directories to be fatal errors. This does not represent an 467438032Speter exposure on systems that have alias files in unwritable 467538032Speter system directories. 467638032Speter SECURITY: disallow .forward or :include: files that are links (hard 467738032Speter or soft) if the parent directory (or any directory in the 467838032Speter path) is writable by anyone other than the owner. This is 467938032Speter similar to the previous case for user files. This change 468038032Speter should not affect most systems, but is necessary to prevent 468138032Speter an attacker who can write the directory from pointing such 468238032Speter files at other files that are readable only by the owner. 468338032Speter SECURITY: Tighten safechown rules: many systems will say that they 468438032Speter have a safe (restricted to root) chown even on files that 468538032Speter are mounted from another system that allows owners to give 468638032Speter away files. The new rules are very strict, trusting file 468738032Speter ownership only in those few cases where the system has 468838032Speter been verified to be at least as paranoid as necessary. 468938032Speter However, it is possible to relax the rules to partially 469038032Speter trust the ownership if the directory path is not world or 469138032Speter group writable. This might allow someone who has a legitimate 469238032Speter :include: file (referenced directly from /etc/aliases) to 469338032Speter become another non-root user if the :include: file is in a 469438032Speter non-writable directory on an NFS-mounted filesystem where 469538032Speter the local system says that giveaway is denied but it is 469638032Speter actually permitted. I believe this to be a very small set 469738032Speter of cases. If in doubt, do not point :include: aliases at 469838032Speter NFS-mounted filesystems. 469938032Speter SECURITY: When setting a numeric group id using the RunAsUser option 470038032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 470138032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 470238032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 470338032Speter The user id was still set properly. Problem noted by Uli 470438032Speter Pralle of the Technical University of Berlin. 470538032Speter Save the initial gid set for use when checking for if the 470638032Speter PrivacyOptions=restrictmailq option is set.

Patch 471338032Speter from Theo de Raadt. 471438032Speter The "Message is too large" error didn't successfully bounce the error 471538032Speter back to the sender.

Note that this should really 474738032Speter be fixed in the zone file for the domain. Problem noted by 474838032Speter Joe Rhett of Navigist, Inc. 474938032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 475038032Speter the message as having been tried; otherwise the next queue 475138032Speter run will not realize that this is a second attempt and will 475238032Speter retry immediately. Problem noted by Bryan Costales of 475338032Speter Mercury Mail. 475438032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 475538032Speter will be run until the later setting of the clock is reached. 475638032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 475738032Speter Morgan Stanley. 475838032Speter If the load average rises above the cutoff threshold (above which 475938032Speter sendmail will not process the queue at all) during a queue 476038032Speter run, abort the queue run immediately. Problem noted by 476138032Speter Bryan Costales of Mercury Mail. 476238032Speter The variable queue processing algorithm (based on the message size, 476338032Speter number of recipients, message precedence, and job age) was 476438032Speter non-functional -- either the entire queue was processed or 476538032Speter none of the queue was processed. The updated algorithm 476638032Speter does no queue run if a single recipient zero size job will 476738032Speter not be run. 476838032Speter If there is a fatal ("panic") message that will cause sendmail to 476938032Speter die immediately, never hold the error message for future 477038032Speter printing. 477138032Speter Force ErrorMode=print in -bt mode so that all errors are printed 477238032Speter regardless of the setting of the ErrorMode option in the 477338032Speter configuration file. Patch from Gregory Neil Shapiro. 477438032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 477538032Speter routine available in one of the libraries. Use it in conf.h. 477638032Speter The -m (match only) flag now works on host class maps. 477738032Speter If class hash or btree maps are rebuilt, sendmail will now detect 477838032Speter this and reopen the map. Previously, they could give 477938032Speter erroneous results during a single message processing 478038032Speter (but would recover when the next message was received). 478138032Speter Don't delete zero length queue files when doing queue runs until the 478238032Speter files are at least ten minutes old. This avoids a potential 478338032Speter race condition: the creator creates the qf file, getting back 478438032Speter a file descriptor. The queue runner locks it and deletes it 478538032Speter because it is zero length. The creator then writes the 478638032Speter descriptor that is now for a disconnected file, and the 478738032Speter job goes away. Based on a suggestion by Bryan Costales. 478838032Speter When determining the "validated" host name ($_ macro), do a forward 478938032Speter (A) DNS lookup on the result of the PTR lookup and compare 479038032Speter results. If they differ or if the PTR lookup fails, tag the 479138032Speter address as "may be forged". 479238032Speter Log null connections (i.e., hosts that connect but do not do any 479338032Speter substantive activity on the connection before disconnecting; 479438032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 479538032Speter Always permit "writes" to /dev/null regardless of the link count. 479638032Speter This is safe because /dev/null is special cased, and no open 479738032Speter or write is ever actually attempted. Patch from Villy Kruse 479838032Speter of TwinCom. 479938032Speter If a message cannot be sent because of a 552 (exceeded storage 480038032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 480138032Speter was given, don't return the body in the bounce, since there 480238032Speter is a very good chance that the message will double-bounce. 480338032Speter Fix possible line truncation if a quoted-printable had an =00 escape 480438032Speter in the body. Problem noted by Charles Karney of the Princeton 480538032Speter Plasma Physics Laboratory. 480638032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 480738032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 480838032Speter Institute. 480938032Speter The MaxDaemonChildren option wasn't applying to queue runs as 481038032Speter documented. Note that this increases the potential denial 481138032Speter of service problems with this option: an attacker can 481238032Speter connect many times, and thereby lock out queue runs as well 481338032Speter as incoming connections. If you use this option, you should 481438032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 481538032Speter to avoid this attack. Failure to limit noted by Matthew 481638032Speter Dillon of BEST Internet Communications. 481738032Speter Always give a message in newaliases if alias files cannot be 481838032Speter opened instead of failing silently. Suggested by Gregory 481938032Speter Neil Shapiro. This change makes the code match the O'Reilly 482038032Speter book (2nd edition). 482138032Speter Some older versions of the resolver could return with h_errno == -1 482238032Speter if no name server could be reached, causing mail to bounce 482338032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 482438032Speter John Beck of SunSoft. 482538032Speter If a :include: file is owned by a user that does not have an entry 482638032Speter in the passwd file, sendmail could dereference a null pointer. 482738032Speter Problem noted by Satish Mynam of Sun Microsystems. 482838032Speter Take precautions to make sure that the SMTP protocol cannot get out 482938032Speter of sync if (for example) an alias file cannot be opened. 483038032Speter Fix a possible race condition that can cause a SIGALRM to come in 483138032Speter immediately after a SIGHUP, causing the new sendmail to die. 483238032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 483338032Speter from Villy Kruse of TwinCom. 483438032Speter Ignore improperly formatted SMTP reply codes. Previously these were 483538032Speter partially processed, which could cause confusing error 483638032Speter returns. 483738032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 483838032Speter on some architectures. 483938032Speter Portability: 484038032Speter A/UX: from Jim Jagielski of NASA/GSFC. 484138032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 484238032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 484338032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 484438032Speter defined. Problem reported by A Sun of the University 484538032Speter of Washington. 484638032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 484738032Speter the system rather than guessing at compile time. 484838032Speter Patch contributed by John Beck of Sun Microsystems. 484938032Speter Intel Paragon: from Wendy Lin of Purdue University. 485038032Speter GNU Hurd: from Miles Bader of the GNU project. 485138032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 485238032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 485338032Speter Unfortunately releasing them opens a race condition, 485438032Speter but there appears to be no fix for this. Patch from 485538032Speter Gregory Neil Shapiro. 485638032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 485738032Speter Solaris: a bug in strcasecmp caused characters with the 485838032Speter high order bit set to apparently randomly match 485938032Speter letters -- for example, $| (0233) matches "i" and "I". 486038032Speter Problem noted by John Gregson of the University of 486138032Speter Cambridge. 486238032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 486338032Speter Kari Hurtta. 486438032Speter IRIX 6.x: Create Makefiles for systems that claim to be 486538032Speter IRIX64 but are 6.2 or higher (so use the regular 486638032Speter IRIX Makefile). 486738032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 486838032Speter Problem noted by Eric Hagberg of Morgan Stanley. 486938032Speter CONFIG: Some canonification was still done for UUCP-like addresses 487038032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 487138032Speter Brian Candler. 487238032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 487338032Speter local names as local. Problem noted by Jeff Polk of BSDI; 487438032Speter fix provided by Gregory Neil Shapiro. 487538032Speter CONFIG: The "local:user" syntax entries in mailertables and other 487638032Speter "mailer:user" syntax locations returned an incorrect value 487738032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 487838032Speter CONFIG: Retain "+detail" information when forwarding mail to a 487938032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 488038032Speter Guenther of Gustavus Adolphus College. 488138032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 488238032Speter rules are the same as for aliasing. Based on a patch from 488338032Speter Gregory Neil Shapiro. 488438032Speter CONFIG: Break up parsing rules into several pieces; this should 488538032Speter have no functional change in this release, but makes it 488638032Speter possible to have better anti-spam rulesets in the future. 488738032Speter CONFIG: Disallow double dots in host names to avoid having the 488838032Speter HostStatusDirectory store status under the wrong name. 488938032Speter In some cases this can be used as a denial-of-service attack. 489038032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 489138032Speter Gregory Neil Shapiro. 489238032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 489338032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 489438032Speter don't include From_, and convert to 8-bit). Suggestions 489538032Speter from Kimmo Suominen and Roderick Schertler. 489664562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 489738032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 489838032Speter was specified, even when it wasn't. 489938032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 490038032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 490138032Speter "slip in" a symbolic link between the lstat(2) call and the 490238032Speter exclusive open. This is only a problem on System V derived 490338032Speter systems that allow an exclusive create on files that are 490438032Speter symbolic links pointing nowhere. 490538032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 490638032Speter not reset back to root, which on some systems would cause 490738032Speter later mailboxes to fail. Also, any partial message would 490838032Speter not be truncated, which could result in repeated deliveries. 490938032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 491038032Speter developers). 491138032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 491238032Speter change to the sendmail map code was made in 8.8.3. Problem 491338032Speter noted by Gregory Neil Shapiro. 491438032Speter MAKEMAP: Give warnings on file problems such as map files that are 491590792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 491638032Speter often run as root and hence has the potential for the same 491738032Speter sorts of problems as alias rebuilds. 491838032Speter MAKEMAP: Change compilation so that it will link properly on 491938032Speter NEXTSTEP. 492038032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 492138032Speter Accept an optional list of arguments following the server 492238032Speter name for the ETRN arguments to use (instead of $=w). Other 492338032Speter miscellaneous bug fixes. From Christian von Roques via 492438032Speter John Beck of Sun Microsystems. 492538032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 492638032Speter Perl script converts GECOS information in the /etc/passwd 492738032Speter file into aliases, allowing for faster access to full name 492838032Speter lookups; it is also clever about adding aliases (to root) 492938032Speter for system accounts. 493038032Speter NEW FILES: 493138032Speter src/safefile.c 493238032Speter cf/ostype/gnuhurd.m4 493338032Speter cf/ostype/irix6.m4 493438032Speter contrib/passwd-to-alias.pl 493538032Speter src/Makefiles/Makefile.IRIX64.6.1 493638032Speter src/Makefiles/Makefile.IRIX64.6.x 493738032Speter RENAMED FILES: 493838032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 493938032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 494038032Speter 494164562Sgshapiro8.8.5/8.8.5 1997/01/21 494238032Speter SECURITY: Clear out group list during startup. Without this, sendmail 494338032Speter will continue to run with the group permissions of the caller, 494438032Speter even if RunAsUser is specified. 494538032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 494638032Speter to any known attack, but it's best to be conservative. 494738032Speter Suggested by Peter Wemm of DIALix. 494838032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 494938032Speter security implications. Patch from Alex Garthwaite of the 495038032Speter University of Pennsylvania. 495138032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 495238032Speter would truncate the address after "Full". Although the -f 495338032Speter syntax is incorrect (since it is in the envelope, it 495438032Speter shouldn't have comments and full names), the failure mode 495538032Speter was unnecessarily awful. 495638032Speter Fix a possible null pointer dereference when converting 8-bit data 495738032Speter to a 7-bit format. Problem noted by Jim Hutchins of 495838032Speter Sandia National Labs and David James of British Telecom. 495938032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 496038032Speter runs. Although this really shouldn't be used (F=9 is for 496138032Speter final delivery only, and using it on an SMTP mailer makes 496238032Speter it possible for a message to be converted from 8->7->8->7 496338032Speter bits several times), it shouldn't have failed with a syserr. 496438032Speter Problem noted by Eric Hagberg of Morgan Stanley. 496538032Speter _Really_ fix the multiple :maildrop code in the user database 496638032Speter module. Patch from Roy Mongiovi of Georgia Tech. 496738032Speter Let F lines in the configuration file actually read root-only 496838032Speter files if the configuration file is safe. Based on a 496938032Speter patch from Keith Reynolds of SCO. 497038032Speter ETRN followed by QUIT would hold the connection open until the queue 497138032Speter run completed. Problem noted by Truck Lewis of TDK 497238032Speter Semiconductor Corp. 497338032Speter It turns out that despite the documentation, the TCP wrappers library 497438032Speter does _not_ log rejected connections. Do the logging ourselves. 497538032Speter Problem noted by Fletcher Mattox of the University of Texas 497638032Speter at Austin. 497738032Speter If sendmail finds a qf file in its queue directory that is an unknown 497838032Speter version (e.g., when backing out to an old version), the 497938032Speter error is reported on every queue run. Change it to only 498038032Speter give the error once (and rename the qf => Qf). Patch from 498138032Speter William A. Gianopoulos of Raytheon Company. 498238032Speter Start a new session when doing background delivery; currently it 498338032Speter ignored signals but didn't start a new signal, that caused 498438032Speter some problems if a background process tried to send mail 498538032Speter under certain circumstances. Problem noted by Eric Hagberg 498638032Speter of Morgan Stanley; fix from Kari Hurtta. 498738032Speter Simplify test for skipping a queue run to just check if the current 498838032Speter load average is >= the queueing load average. Previously 498938032Speter the check factored in some other parameters that caused it 499038032Speter to essentially never skip the queue run. Patch from Bryan 499138032Speter Costales. 499238032Speter If the SMTP server is running in "nullserver" mode (that is, it is 499338032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 499438032Speter (25) commands; this helps prevent a bad guy from putting 499538032Speter you into a tight loop as a denial-of-service attack. Based 499638032Speter on an e-mail conversation with Brad Knowles of AOL. 499738032Speter Slow down when too many "light weight" commands have been issued; 499838032Speter this helps prevent a class of denial-of-service attacks. 499938032Speter The current values and defaults are: 500038032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 500138032Speter MAXHELOCOMMANDS 3 HELO, EHLO 500238032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 500338032Speter MAXETRNCOMMANDS 8 ETRN 500438032Speter These will probably be configurable in a future release. 500538032Speter On systems that have uid_t typedefed to be an unsigned short, programs 500638032Speter that had the F=S flag and no U= equate would be invoked with 500738032Speter the real uid set to 65535 rather than being left unchanged. 500838032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 500938032Speter by Steve Hubert of the University of Washington, Seattle. 501038032Speter Mail that was Quoted-Printable encoded and had a soft line break on 501138032Speter the last line (i.e., an incomplete continuation) had the last 501238032Speter line dropped. Since this appears to be illegal it isn't 501338032Speter clear what to do with it, but flushing the last line seems 501438032Speter to be a better "fail soft" approach. Based on a patch from 501538032Speter Eric Hagberg. 501638032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 501738032Speter bogus HELO command still causes the "Polite people say HELO 501838032Speter first" error message.

Problem noted by Ronan KERYELL 506138032Speter of Centre de Recherche en Informatique de l'�cole Nationale 506238032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 506338032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 506438032Speter such as LUSER_RELAY. This change permits the following 506538032Speter syntaxes: ``local:'' will send to the same user on the 506638032Speter local machine (e.g., in a mailertable entry for "host", 506738032Speter ``local:'' will cause an address addressed to user@host to 506838032Speter go to user on the local machone). ``local:user'' will send 506938032Speter to the named user on the local machine. ``local:user@host'' 507038032Speter is equivalent to ``local:user'' (the host is ignored). In 507138032Speter all cases, the original user@host is passed in $@ (i.e., the 507238032Speter detail information). Inspired by a report from Michael Fuhr. 507338032Speter CONFIG: Strip quotes from the first word of an "error:" host 507438032Speter indication. This lets you set (for example) the LUSER_RELAY 507538032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 507638032Speter of the \" so that the resulting string is properly quoted. 507738032Speter Problem noted by Gregory Neil Shapiro of WPI. 507838032Speter OP.ME: documentation was inconsistent about whether sendmail did a 507938032Speter NOOP or a RSET to probe the connection (it does a RSET). 508038032Speter Inconsistency noted by Deeran Peethamparam. 508138032Speter OP.ME: insert additional blank pages so it will print properly on 508238032Speter a duplex printer.

The solution is to disallow any 508938032Speter files that have hard links -- this will affect .forward, 509038032Speter :include:, and output files. Problem noted by Terry 509138032Speter Kyriacopoulos of Interlog Internet Services. As a 509238032Speter workaround, set UnsafeGroupWrites -- always a good idea. 509338032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 509438032Speter is, it is possible to do a denial-of-service attack on 509538032Speter MX hosts that rely on the use of the null MX list. There 509638032Speter is no danger if you have this option turned off (the default). 509738032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 509838032Speter unsafe. I know of no specific attack against this, although 509938032Speter a denial-of-service attack is probably possible, but in theory 510038032Speter you should not be able to safely tweak anything that affects 510138032Speter the permissions that are used when mail is delivered. 510238032Speter Purgestat could go into an infinite loop if one of the host status 510338032Speter directories somehow became empty. Problem noted by Roy 510438032Speter Mongiovi of Georgia Tech. 510538032Speter Processes got "lost" when counting children due to a race condition. 510638032Speter This caused "proc_list_probe: lost pid" messages to be logged. 510738032Speter Problem noted by several people. 510838032Speter On systems with System V SIGCLD child signal semantics (notably AIX 510938032Speter and HP-UX), mail transactions would print the message "451 511038032Speter SMTP-MAIL: lost child: No child processes". Problem noted 511138032Speter by several people. 511238032Speter Miscellaneous compiler warnings on picky compilers (or when setting 511338032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 511438032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 511538032Speter not be persistent between runs, since they are based on the 511638032Speter message rather than the host. Problem noted by Matt Dillon 511738032Speter of Best Internet Communications. 511838032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 511938032Speter of NCR (a.k.a., AT&T Global Information Solutions). 512038032Speter Avoid the possibility of having a child daemon run to completion 512138032Speter (including closing the SMTP socket) before the parent has 512238032Speter had a chance to close the socket; this can cause the parent 512338032Speter to hang for a long time waiting for the socket to drain. 512438032Speter Patch from Don Lewis of TDK Semiconductor. 512538032Speter If the fork() failed in a queue run, the queue runners would not be 512638032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 512738032Speter Some error conditions in ETRN could cause output without an SMTP 512838032Speter status code. Problem noted by Don Lewis. 512938032Speter Multiple :maildrop addresses in the user database didn't work properly. 513038032Speter Patch from Roy Mongiovi of Georgia Tech. 513138032Speter Add ".db" automatically onto any user database spec that does not 513238032Speter already have it; this is for consistency with makemap, the 513338032Speter K line, and the documentation. Inconsistency pointed out 513438032Speter by Roy Mongiovi. 513538032Speter Allow sendmail to be properly called in nohup mode. Patch from 513638032Speter Kyle Jones of UUNET. 513738032Speter Change ETRN to ignore but still update host status files; previously 513838032Speter it would ignore them and not save the updated status, which 513938032Speter caused stale information to be maintained. Based on a patch 514038032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 514138032Speter ETRN ignore the MinQueueAge option. 514238032Speter Patch long term host status to recover more gracefully from an empty 514338032Speter host status file condition. Patch from NAKAMURA Motonori 514438032Speter of Kyoto University. 514538032Speter Several patches to signal handling code to fix potential race 514638032Speter conditions from Don Lewis. 514738032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 514838032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 514938032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 515038032Speter compile flag; use NETINET instead. Solution based on a 515138032Speter patch from Bryan Costales. 515238032Speter PORTABILITY FIXES: 515338032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 515438032Speter /etc/security/passwd file when called as root. This 515538032Speter is very slow on some systems. To speed it up, use the 515638032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 515738032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 515838032Speter SCO 5.x: include -lprot in the Makefile.

Problem 519738032Speter noted by Eric Bishop of Virginia Tech. 519838032Speter When doing text-based host canonification (typically /etc/hosts 519938032Speter lookup), a null host name would match any /etc/hosts entry 520038032Speter with space at the end of the line. Problem noted by Steve 520138032Speter Hubert of the University of Washington, Seattle. 520238032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 520338032Speter Problem reported by Tom Smith of Digital Equipment Corp. 520438032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 520538032Speter size PACKETSZ (512) is not sufficient for some nameserver 520638032Speter answers containing very many resource records. The resolver 520738032Speter may also switch to TCP and retry if it detects UDP packet 520838032Speter overflow. Also, allow for the fact that the resolver 520938032Speter routines res_query and res_search return the size of the 521038032Speter *un*truncated answer in case the supplied answer buffer it 521138032Speter not big enough to accommodate the entire answer. Patch from 521238032Speter Eric Wassenaar. 521338032Speter Improvements to MaxDaemonChildren code. If you think you have too 521438032Speter many children, probe the ones you have to verify that they 521538032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 521638032Speter Also, do this probe before growing the vector of children 521738032Speter pids; this previously caused the vector to grow indefinitely 521838032Speter due to a race condition. Problem reported by Kyle Jones of 521938032Speter UUNET. 522038032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 522138032Speter O_EXLOCK to zero; this fools the map compilation code into 522238032Speter thinking that it can avoid race conditions by locking on open. 522338032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 522438032Speter Leif Erlingsson of Data Lege. 522538032Speter Always call res_init() on startup (if compiled in, of course) to 522638032Speter allow the sendmail.cf file to tweak resolver flags; without 522738032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 522838032Speter Andrew Sun of Merrill Lynch. 522938032Speter Improvements to host status printing code. Suggested by Steve Hubert 523038032Speter of the University of Washington, Seattle. 523138032Speter Change MinQueueAge option processing to do the check for the job age 523238032Speter when reading the queue file, rather than at the end; this 523338032Speter avoids parsing the addresses, which can do DNS lookups. 523438032Speter Problem noted by John Beck of InReference, Inc. 523538032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 523638032Speter properly escaped. Problem noted by Peter Nilsson of the 523738032Speter University of Linkoping. 523838032Speter In some cases, sendmail would retain root permissions during queue 523938032Speter runs even if RunAsUser was set. Problem noted by Mark 524038032Speter Thomas of Mark G. Thomas Consulting. 524138032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 524238032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 524338032Speter the envelope, and the receiving SMTP server speaks DSN, then 524438032Speter the DSN would be both generated locally and propagated to the 524538032Speter other end. 524638032Speter The U= mailer field didn't correctly extract the group id if the 524738032Speter user id was numeric.

If this option is null (as 532138032Speter opposed to undefined) it can cause "null signature" syserrs 532238032Speter on illegal host names. 532338032Speter If a Base64 encoded text/plain message has no trailing newline in 532438032Speter the encoded text, conversion back to 8 bits will drop the 532538032Speter final line. Problem noted by Pierre David. 532638032Speter If running with a RunAsUser, sendmail would give bogus "cannot 532738032Speter setuid" (or seteuid, or setreuid) messages on some systems. 532838032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 532938032Speter Always print error messages in -bv mode -- previously, -bv would 533038032Speter be absolutely silent on errors if the error mode was sent 533138032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 533238032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 533338032Speter term host status. This is necessary because it is common 533438032Speter to do this when you know a host has just come back up. 533538032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 533638032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 533738032Speter University of Leicester. 533838032Speter If a service (such as NIS) is specified as the last entry in the 533938032Speter service switch, but that service is not compiled in, sendmail 534038032Speter would return a temporary failure when an entry was not found 534138032Speter in the map. This caused the message to be queued instead of 534238032Speter bouncing immediately.

Pointed out by Munenari Hirayama of 537538032Speter NSC (Japan). 537638032Speter A message that didn't terminate with a newline would (sometimes) not 537738032Speter have the trailing "." added properly in the SMTP dialogue, 537838032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 537938032Speter The DaemonPortOptions suboption to bind to a particular address was 538038032Speter incorrect and nonfunctional due to a misunderstanding of the 538138032Speter semantics of binding on a passive socket.

In order to avoid 538638032Speter trashing memory, the buffer for all names has only been 538738032Speter slightly increased in size, to 12.8K from 10.2K -- this means 538838032Speter that if a single name had 100 MX records, the average size 538938032Speter of those records could not exceed 128 bytes.

Berkeley. 539338032Speter Print q_statdate and q_specificity in address structure debugging 539438032Speter printout. 539538032Speter Expand MCI structure flag bits for debugging output. 539638032Speter Support IPv6-style domain literals, which can have colons between 539738032Speter square braces. 539838032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 539938032Speter this is an attempt to track down a bug that one person seems 540038032Speter to be having (it may be a Solaris bug!). 540138032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 540238032Speter this caused the NOTIFY info to sometimes be lost. Problem 540338032Speter pointed out by Claus Assmann of the 540438032Speter Christian-Albrechts-University of Kiel. 540538032Speter The statistics gathered in the sendmail.st file were too high; in 540638032Speter some cases failures (e.g., user unknown or temporary failure) 540738032Speter would count as a delivery as far as the statistics were 540838032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 540938032Speter Systems that don't have flock() would not send split envelopes in 541038032Speter the initial run. Problem pointed out by Leonard Zubkoff of 541138032Speter Dandelion Digital. 541238032Speter Move buffer overflow checking -- these primarily involve distrusting 541338032Speter results that may come from NIS and DNS. 541438032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 541538032Speter include <paths.h> and hence had the wrong pathnames for a few 541638032Speter things like /var/tmp. Reported by Matthew Green. 541738032Speter Conditions were reversed for the Priority: header, resulting in all 541838032Speter values being interpreted as non-urgent except for non-urgent, 541938032Speter which was interpreted as normal. Patch from Bryan Costales. 542038032Speter The -o (optional) flag was being ignored on hash and btree maps 542138032Speter since 8.7.2. Fix from Bryan Costales. 542238032Speter Content-Types listed in class "q" will always be encoded as 542338032Speter Quoted-Printable (or more accurately, will never be encoded 542438032Speter as base64). The class can have primary types (e.g., "text") 542538032Speter or full types (e.g., "text/plain"). Based on a suggestion by 542638032Speter Marius Olafsson of the University of Iceland. 542738032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 542838032Speter dialogue) so it can be passed to programs in mailers. 542938032Speter Define ${bodytype} to be the body type (from the -B flag or the 543038032Speter BODY= ESMTP parameter) so it can be passed to programs in 543138032Speter mailers. 543238032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 543338032Speter flag is set in the mailer descriptor. Suggested by John 543438032Speter Myers of CMU. 543538032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 543638032Speter The command takes a host name; data for that host is 543738032Speter immediately (and asynchronously) flushed. Because this shares 543838032Speter the -qR implementation, other hosts may be attempted, but 543938032Speter there should be no security implications. Implementation 544038032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 544138032Speter Add three new command line flags to pass in DSN parameters: -V envid 544238032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 544338032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 544438032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 544538032Speter that the -N flag applies to all recipients; there is no way 544638032Speter to specify per-address notifications on the command line, 544738032Speter nor is there an equivalent for the ORCPT= per-address 544838032Speter parameter. 544938032Speter Restore LogLevel option to be safe (it can only be increased); 545038032Speter apparently I went into paranoid mode between 8.6 and 8.7 545138032Speter and made it unsafe. Pointed out by Dabe Murphy of the 545238032Speter University of Maryland. 545338032Speter New logging on log level 15: all SMTP traffic. Patches from 545438032Speter Andrew Gross of San Diego Supercomputer Center. 545538032Speter NetInfo property value searching code wasn't stopping when it found 545638032Speter a match. This was causing the wrong values to be found (and 545738032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 545838032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 545938032Speter out by Bill Wisner of Electronics for Imaging that you can't 546038032Speter use the bracket address form for the MAIL_HUB macro, since 546138032Speter that causes the brackets to remain in the envelope recipient 546238032Speter address used for delivery. The simple fix (stripping off the 546338032Speter brackets in the config file) breaks the use of IP literal 546438032Speter addresses. This flag will solve that problem. 546538032Speter Add MustQuoteChars option. This is a list of characters that must 546638032Speter be quoted if they are found in the phrase part of an address 546738032Speter (that is, the full name part). The characters @,;:\()[] are 546838032Speter always in this list and cannot be removed. The default is 546938032Speter this list plus . and ' to match RFC 822. 547038032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 547138032Speter that do not include a host name for back compatibility with 547238032Speter some stupid SMTP clients. Setting this violates RFC 1123 547338032Speter section 5.2.5. 547438032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 547538032Speter rejecting connections if it has more than this many 547638032Speter outstanding children accepting mail. Note that you may 547738032Speter see more processes than this because of outgoing mail; this 547838032Speter is for incoming connections only. 547938032Speter Add ConnectionRateThrottle option. If set to a positive value, the 548038032Speter number of incoming SMTP connections that will be permitted 548138032Speter in a single second is limited to this number. Connections are 548238032Speter not refused during this time, just deferred. The intent is to 548338032Speter flatten out demand so that load average limiting can kick in. 548438032Speter It is less radical than MaxDaemonChildren, which will stop 548538032Speter accepting connections even if all the connections are idle 548638032Speter (e.g., due to connection caching). 548738032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 548838032Speter specifies how long cached information about the state of a 548938032Speter host will be kept before they are considered stale and the 549038032Speter host is retried. If you are using persistent host status 549138032Speter (i.e., the HostStatusDirectory option is set) this will apply 549238032Speter between runs; otherwise, it applies only within a single queue 549338032Speter run and hence is useful only for hosts that have large queues 549438032Speter that take a very long time to run. 549538032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 549638032Speter into being a single line even if they had newlines in them 549738032Speter when read. This is to get around a botch in Lotus Notes. 549838032Speter Text class maps were totally broken -- if you ever retrieved the last 549938032Speter item in a table it would be truncated. Problem noted by 550038032Speter Gregory Neil Shapiro of WPI. 550138032Speter Extend the lines printed by the mailq command (== the -bp flag) when 550238032Speter -v is given to 120 characters; this allows more information 550338032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 550438032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 550538032Speter this was treated as end-of-input. Problem noted by Bryan 550638032Speter Costales. 550738032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 550838032Speter to the queue file. Fix from John Hughes of Atlantic 550938032Speter Technologies, Inc. 551038032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 551138032Speter if this happens in a queue run it can cause nasty delays. 551238032Speter Problem noted by Mark Horton of AT&T. 551338032Speter If userdb entries pointed to userdb entries, and there were multiple 551438032Speter values for a given key, the database cursor would get 551538032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 551638032Speter of Georgia Tech. Fixed by reading all the values and creating 551738032Speter a comma-separated list; thus, the -v output will be somewhat 551838032Speter different for this case. 551938032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 552038032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 552138032Speter of Stanford University. 552238032Speter When envelopes were split due to aliases with owner- aliases, and 552338032Speter there was some error on one of the lists, more than one of 552438032Speter the owners would get the message. Problem pointed out by 552538032Speter Roy Mongiovi of Georgia Tech. 552638032Speter Detect excessive recursion in macro expansions, e.g., $X defined 552738032Speter in terms of $Y which is defined in terms of $X. Problem 552838032Speter noted by Bryan Costales; patch from Eric Wassenaar. 552938032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 553038032Speter some cases get trashed causing bogus From_ lines. Fix from 553138032Speter Kyle Jones of UUNET. 553238032Speter When doing load average initialization, if the nlist call for avenrun 553338032Speter failed, the second and subsequent lookups wouldn't notice 553438032Speter that fact causing bogus load averages to be returned. Noted 553538032Speter by Casper Dik of Sun Holland. 553638032Speter Fix problem with incompatibility with some versions of inet_aton that 553738032Speter have changed the return value to unsigned, so a check for an 553838032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 553938032Speter This could cause mail to addresses such as [foo.com] to bounce 554038032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 554138032Speter Pasteur Institute. 554238032Speter DSNs were inconsistent if a failure occurred during the DATA phase 554338032Speter rather than the RCPT phase: the Action: would be correct, but 554438032Speter the detailed status information would be wrong. Problem noted 554538032Speter by Bob Snyder of General Electric Company. 554638032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 554738032Speter that this is the initial MUA->MTA submission. The flag current 554838032Speter does nothing, but in future releases (when MUAs start using 554938032Speter these flags) it will probably turn on things like DNS 555038032Speter canonification. 555138032Speter Default end-of-line string (E= specification on mailer [M] lines) 555238032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 555338032Speter mailers. 555438032Speter Change the internal definition for the *file* and *include* mailers 555538032Speter to have $u in the argument vectors so that they aren't 555638032Speter misinterpreted as SMTP mailers and thus use \r\n line 555738032Speter termination. This will affect anyone who has redefined 555838032Speter either of these in their configuration file. 555938032Speter Don't assume that IDENT servers close the connection after a query; 556038032Speter responses can be newline terminated. From Terry Kennedy of 556138032Speter St. Peter's College. 556238032Speter Avoid core dumps on erroneous configuration files that have 556338032Speter $#mailer with nothing following. From Bryan Costales. 556438032Speter Avoid null pointer dereference with high debug values in unlockqueue. 556538032Speter Fix from Randy Martin of Clemson University. 556638032Speter Fix possible buffer overrun when expanding very large macros. Fix 556738032Speter from Kyle Jones of UUNET. 556838032Speter After 25 EXPN or VRFY commands, start pausing for a second before 556938032Speter processing each one. This avoids a certain form of denial 557038032Speter of service attack. Potential attack pointed out by Bryan 557138032Speter Costales. 557238032Speter Allow new named (not numbered!) config file rules to do validity 557338032Speter checking on SMTP arguments: check_mail for MAIL commands and 557438032Speter check_rcpt for RCPT commands. These rulesets can do anything 557538032Speter they want; their result is ignored unless they resolve to the 557638032Speter $#error mailer, in which case the indicated message is printed 557738032Speter and the command is rejected. Similarly, the check_compat 557838032Speter ruleset is called before delivery with "from_addr $| to_addr" 557938032Speter (the $| is a meta-symbol used to separate the two addresses); 558038032Speter it can give a "this sender can't send to this recipient" 558138032Speter notification. Note that this patch allows $| to stand alone 558238032Speter in rulesets. 558338032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 558438032Speter that have the name, IP address, and port number (respectively) 558538032Speter of the SMTP client (that is, the entity at the other end of 558638032Speter the connection. These can be used in (e.g.) check_rcpt to 558738032Speter verify that someone isn't trying to relay mail through your 558838032Speter host inappropriately. Be sure to use the deferred evaluation 558938032Speter form, for example $&{client_name}, to avoid having these bound 559038032Speter when sendmail reads the configuration file. 559138032Speter Add new config file rule check_relay to check the incoming connection 559238032Speter information. Like check_compat, it is passed the host name 559338032Speter and host address separated by $| and can reject connections 559438032Speter on that basis. 559538032Speter Allow IDA-style recursive function calls. Code contributed by Mark 559638032Speter Lovell and Paul Vixie. 559738032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 559838032Speter a virtual UUCP address using either a domain address or the $k 559938032Speter macro. Based on code contributed by Mark Lovell and Paul 560038032Speter Vixie. 560138032Speter Add Stanford LDAP map. Requires special libraries that are not 560238032Speter included with sendmail. Contributed by Booker C. Bense 560338032Speter <bbense@networking.stanford.edu>; contact him for support. 560438032Speter See also the src/READ_ME file. 560538032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 560638032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 560738032Speter only for debugging deep bits of code where it is important to 560838032Speter distinguish between the single-character metasymbol $+ and the 560938032Speter two characters $, +. 561038032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 561138032Speter debug_dumpstate. 561238032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 561338032Speter files that are group writable are considered "unsafe" -- that 561438032Speter is, programs and files referenced from such files are not 561538032Speter valid recipients. 561638032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 561738032Speter name that was not in DNS or was a domain-literal. Problem 561838032Speter noted by Tom May. 561938032Speter Change the introduction to error messages to more clearly delineate 562038032Speter permanent from temporary failures; if both existed in a 562138032Speter single message it could be confusing. Suggested by John 562238032Speter Beck of InReference, Inc. 562338032Speter The IngoreDot (i) option didn't work for lines that were terminated 562438032Speter with CRLF. Problem noted by Ted Stockwell of Secure 562538032Speter Computing Corporation. 562638032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 562738032Speter message headers. Problem reported by Matt Dillon of Best 562838032Speter Internet Communications. 562938032Speter Check for bogus characters in the 0200-0237 range; since these are 563038032Speter used internally, very strange errors can occur if those 563138032Speter characters appear in headers. Problem noted by Anders Gertz 563238032Speter of Lysator. 563338032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 563438032Speter recipient mailer has the F=9 flag set, and only works on 563538032Speter text/plain body types. Code contributed by Marius Olafsson 563638032Speter of the University of Iceland. 563738032Speter Special case "postmaster" name so that it is always treated as lower 563838032Speter case in alias files regardless of configuration settings; 563938032Speter this prevents some potential problems where "Postmaster" or 564038032Speter "POSTMASTER" might not match "postmaster". In most cases 564138032Speter this change is a no-op. 564238032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 564338032Speter Costales. 564438032Speter The -a map flag was ignored for dequote maps. Problem noted by 564538032Speter Bryan Costales. 564638032Speter Fix core dump when a lookup of a class "prog" map returns no 564738032Speter response. Patch from Bryan Costales. 564838032Speter Log instances where sendmail is deferring or rejecting connections 564938032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 565038032Speter Include port number in process title for network daemons. Suggested 565138032Speter by Kyle Jones of UUNET. 565238032Speter Send ``double bounces'' (errors that occur when sending an error 565338032Speter message) to the address indicated in the DoubleBounceAddress 565438032Speter option (default: postmaster). Previously they were always 565538032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 565638032Speter Add new mode, -bD, that acts like -bd in all respects except that 565738032Speter it runs in foreground. This is useful for using with a 565838032Speter wrapper that "watches" system services. Suggested by Kyle 565938032Speter Jones of UUNET. 566038032Speter Fix botch in spacing around (parenthesized) comments in addresses 566138032Speter when the comment comes before the address. Patch from 566238032Speter Motonori Nakamura of Kyoto University. 566338032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 566438032Speter that are being bounced to postmaster, rather than "Returned 566538032Speter mail". This permits the person who is postmaster more 566638032Speter easily determine what messages are to their role as 566738032Speter postmaster versus bounces to mail they actually sent. Based 566838032Speter on a suggestion by Motonori Nakamura. 566938032Speter Add new value "time" for QueueSortOrder option; this causes the queue 567038032Speter to be sorted strictly by the time of submission. Note that 567143730Speter this can cause very bad behavior over slow lines (because 567238032Speter large jobs will tend to delay small jobs) and on nodes with 567338032Speter heavy traffic (because old things in the queue for hosts that 567438032Speter are down delay processing of new jobs). Also, this does not 567538032Speter guarantee that jobs will be delivered in submission order 567638032Speter unless you also set DeliveryMode=queue. In general, it should 567738032Speter probably only be used on the command line, and only in 567838032Speter conjunction with -qRhost.domain. In fact, there are very few 567938032Speter cases where it should be used at all. Based on an 568038032Speter implementation by Motonori Nakamura. 568138032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 568238032Speter the same manner as other rulesets. Previously a temporary 568338032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 568438032Speter of Stanford University. 568538032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 568638032Speter 5yz (permanent failure) code. The next MX host will still be 568738032Speter tried if the connection cannot be opened in the first place 568838032Speter or if the MAIL command returns a 4yz (temporary failure) code. 568938032Speter (It's hard to know what to do here, since neither RFC 974 nor 569038032Speter RFC 1123 specify when to proceed to the next MX host.) 569138032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 569238032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 569338032Speter This causes map lookups that get a temporary failure (e.g., 569438032Speter name server failure) to _not_ defer the delivery of the 569538032Speter message. This should only be used if your configuration file 569638032Speter is prepared to do something sensible in this case. Based on 569738032Speter an idea by Gregory Shapiro of WPI. 569838032Speter Fix problem finding network interface addresses. Patch from 569938032Speter Motonori Nakamura. 570038032Speter Don't reject qf entries that are not owned by your effective uid if 570190792Sgshapiro you are not running set-user-ID; this makes management of 570280785Sgshapiro certain kinds of firewall setups difficult. Patch 570380785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 570438032Speter Add persistent host status. This keeps the information normally 570538032Speter maintained within a single queue run in disk files that are 570638032Speter shared between sendmail instances. The HostStatusDirectory 570738032Speter is the directory in which the information is maintained. If 570838032Speter not set, persistent host status is turned off. If not a full 570938032Speter pathname, it is relative to the queue directory. A common 571038032Speter value is ".hoststat". 571138032Speter There are also two new operation modes: 571238032Speter * -bh prints the status of hosts that have had recent 571338032Speter connections. 571438032Speter * -bH purges the host statuses. No attempt is made to save 571538032Speter recent status information. 571638032Speter This feature was originally written by Paul Vixie of Vixie 571738032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 571838032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 571938032Speter with my insistence that things fit cleanly into the V8 572038032Speter framework is gratefully appreciated. 572138032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 572238032Speter operate). Avoids letting two sendmails on the local machine 572364562Sgshapiro open connections to the same remote host at the same time. 572438032Speter This reduces load on the other machine, but can cause mail to 572538032Speter be delayed (for example, if one sendmail is delivering a huge 572638032Speter message, other sendmails won't be able to send even small 572738032Speter messages). Also, it requires another file descriptor (for the 572838032Speter lock file) per connection, so you may have to reduce 572938032Speter ConnectionCacheSize to avoid running out of per-process 573038032Speter file descriptors. Based on the persistent host status code 573138032Speter contributed by Paul Vixie and Mark Lovell. 573238032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 573338032Speter SafeFileEnvironment option is set. Problem noted by Bryan 573438032Speter Costales. 573538032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 573638032Speter file. Problem noted by Bryan Costales. 573738032Speter If a job was aborted using the interrupt signal (e.g., control-C from 573838032Speter the keyboard), on some occasions an empty df file would be 573938032Speter left around; these would collect in the queue directory. 574038032Speter Problem noted by Bryan Costales. 574138032Speter Change the makesendmail script to enhance the search for Makefiles 574238032Speter based on release number. For example, on SunOS 5.5.1, it will 574338032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 574438032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 574538032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 574638032Speter Webmasters. 574738032Speter When creating maps using "newaliases", always map the keys to lower 574838032Speter case when creating the map unless the -f flag is specified on 574938032Speter the map itself. Previously this was done based on the F=u 575038032Speter flag in the local mailer, which meant you could create aliases 575138032Speter that you could never access. Problem noted by Bob Wu of DEC. 575238032Speter When a job was read from the queue, the bits causing notification on 575338032Speter failure or delay were always set. This caused those 575438032Speter notifications to be sent even if NOTIFY=NEVER had been 575538032Speter specified. Problem noted by Steve Hubert of the University 575638032Speter of Washington, Seattle. 575738032Speter Add new configurable routine validate_connection (in conf.c). This 575838032Speter lets you decide if you are willing to accept traffic from 575938032Speter this host. If it returns FALSE, all SMTP commands will return 576038032Speter "550 Access denied". -DTCPWRAPPERS will include support for 576138032Speter TCP wrappers; you will need to add -lwrap to the link line. 576238032Speter (See src/READ_ME for details.) 576338032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 576438032Speter bounces. Some people seemed to think that this could be 576538032Speter confusing (even though it is true). Suggested by Motonori 576638032Speter Nakamura. 576738032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 576838032Speter user early in processing to avoid potential security problems. 576938032Speter However, this means that all .forward and :include: files must 577038032Speter be readable by that user, and all files to be written must be 577138032Speter writable by that user and all programs will be executed by that 577238032Speter user. It is also incompatible with the SafeFileEnvironment 577338032Speter option. In other words, it may not actually add much to 577438032Speter security. However, it should be useful on firewalls and other 577538032Speter places where users don't have accounts and the aliases file is 577638032Speter well constrained. 577738032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 577838032Speter only on the first attempt to delivery to an address. It could 577938032Speter be set to be lower than Timeout.connect on the principle that 578038032Speter the mail should go through quickly to responsive hosts; less 578138032Speter responsive hosts get to wait for the next queue run. 578238032Speter Fix a problem on Solaris that occasionally causes programs 578338032Speter (such as vacation) to hang with their standard input connected 578438032Speter to a UDP port. It also created some signal handling problems. 578538032Speter The problems turned out to be an interaction between vfork(2) 578638032Speter and some of the libraries, particularly NIS/NIS+. I am 578738032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 578838032Speter Change user class map to do the same matching that actual delivery 578938032Speter will do instead of just a /etc/passwd lookup. This adds 579038032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 579138032Speter The Timeout.* options are not safe -- they can be used to create a 579238032Speter denial-of-service attack. Problem noted by Christophe 579338032Speter Wolfhugel. 579443730Speter Don't send PostmasterCopy messages in the event of a "delayed" 579538032Speter notification. Suggested by Barry Bouwsma. 579638032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 579738032Speter option is set, since this disables VERB mode. Suggested 579838032Speter by John Hawkinson of MIT. 579938032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 580038032Speter by Motonori Nakamura of Kyoto University. 580138032Speter Only queue messages on transient .forward open failures if there 580243730Speter were no successful opens. The previous behavior caused it 580338032Speter to queue even if a "fall back" .forward was found. Problem 580438032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 580538032Speter and Computer Science (DISCS), NUS, Singapore. 580638032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 580738032Speter is bouncing because of a MIME error during 8->7 bit conversion; 580838032Speter the encapsulated message will bounce again, causing a loop. 580938032Speter Problem noted by Steve Hubert of the University of Washington. 581038032Speter Create xf (transcript) files using the TempFileMode option value 581138032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 581238032Speter National University of Singapore. 581338032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 581438032Speter detect cases where DefaultUid is set to something that the 581538032Speter system can't cope with. 581638032Speter PORTABILITY FIXES: 581738032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 581838032Speter Atlas International. 581938032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 582038032Speter <bicknell@ufp.org>. 582138032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 582238032Speter work on the first recipient of a message due to a 582338032Speter bug in the getpwent family.

Based on a patch from Randall 586638032Speter Winchester of the University of Maryland. 586738032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 586838032Speter Robert La Ferla of Hot Software. 586938032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 587038032Speter (where "code" is an exit status) on domains (previously 587138032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 587238032Speter Foundation. 587338032Speter CONFIG: hooks for IPv6-style domain literals. 587438032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 587538032Speter if it is undefined the AliasFile option is never set; this 587638032Speter should be transparent for most everyone. Suggested by John 587738032Speter Myers of CMU. 587838032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 587938032Speter domain listed in $=w is masqueraded. With it, only those 588038032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 588138032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 588238032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 588338032Speter hosts under those domains as well as the domain headers 588438032Speter themselves. For example, if a configuration had 588538032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 588638032Speter foo.com would be masqueraded; with it, *.foo.com would be 588738032Speter masqueraded as well. Based on an implementation by Richard 588838032Speter (Pug) Bainter of U. Texas. 588938032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 589038032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 589138032Speter Keys are user names; values are outgoing mail addresses. Yes, 589238032Speter this does overlap with the user database, and figuring out 589338032Speter just when to use which one may be tricky. Based on code 589438032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 589538032Speter from Per Hedeland of Ericsson. 589638032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 589738032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 589838032Speter Keys are either fully qualified addresses or just the host 589938032Speter part (with the @ sign). For example, a table containing: 590038032Speter info@foo.com foo-info 590138032Speter info@bar.com bar-info 590238032Speter @baz.org jane@elsewhere.net 590338032Speter would send all mail destined for info@foo.com to foo-info 590438032Speter (which is presumably an alias), mail addressed to info@bar.com 590538032Speter to bar-info, and anything addressed to anyone at baz.org will 590638032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 590738032Speter and baz.org must all be in $=w. Based on discussions with 590838032Speter a great many people. 590938032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 591038032Speter Suggested by Richard Bainter. 591138032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 591238032Speter "fax" mailer. 591338032Speter CONFIG: allow mailertable entries to resolve to local:user; this 591438032Speter passes the original user@host in to procmail-style local 591538032Speter mailers as the "detail" information to allow them to do 591638032Speter additional clever processing. From Joe Pruett of 591738032Speter Teleport Corporation. Delivery to the original user can 591838032Speter be done by specifying "local:" (with nothing after the colon). 591938032Speter CONFIG: allow any context that takes "mailer:domain" to also take 592038032Speter "mailer:user@domain" to force mailing to the given user; 592138032Speter "local:user" can also be used to do local delivery. This 592238032Speter applies on *_RELAY and in the mailertable entries. Based 592338032Speter on a suggestion by Ribert Kiessling of Easynet. 592438032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 592538032Speter limits the possible domains; this reduces the number of DNS 592638032Speter lookups required to support this feature. For example, 592738032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 592838032Speter to domains under my.site.com. Code contributed by Anthony 592938032Speter Thyssen <anthony@cit.gu.edu.au>. 593038032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 593138032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 593238032Speter of WPI. 593338032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 593438032Speter event you have to define local mailers. Suggested by 593538032Speter Gregory Shapiro of WPI. 593638032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 593738032Speter be misinterpreted as a list:...; syntax. Based on a patch by 593838032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 593938032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 594038032Speter remotely connected. The address host!user was being 594138032Speter converted to host!user@thishost instead of host!user@uurelay. 594238032Speter Problem noted by William Gianopoulos of Raytheon Company. 594338032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 594438032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 594538032Speter "User has moved"; the former wording was confusing if the 594638032Speter new address is still on the local host. Based on a suggestion 594738032Speter by Andreas Luik. 594838032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 594938032Speter However, the class is not pre-initialized to contain root. 595038032Speter Suggested by Gregory Neil Shapiro. 595138032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 595238032Speter Wolfhugel. 595338032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 595438032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 595538032Speter well: this produces a slightly different mailbox format (no 595638032Speter Content-Length: headers), file ownerships and modes are 595738032Speter different (not owned by group mail; mode 600 instead of 660), 595838032Speter and the local mailer flags will have to be tweaked (make them 595938032Speter match bsd4.4) in order to use this mailer. Patches from Paul 596038032Speter Hammann of the Missouri Research and Education Network. 596138032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 596238032Speter was a delivery error, such as if the ownership on the file 596338032Speter was wrong or the mode changed between the initial stat and 596438032Speter the open.

They were not 605038032Speter properly repaired in 8.7.1. 605138032Speter Completely delete the Bcc: header if and only if there are other 605238032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 605338032Speter last being a historic botch, of course). If Bcc: is the 605438032Speter only recipient header in the message, its value is tossed, 605543730Speter but the header name is kept. The old behavior (always keep 605638032Speter the header name and toss the value) allowed primary recipients 605738032Speter to see that a Bcc: went to _someone_. 605838032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 605938032Speter sender to <address> using -f'' syslog messages. Suggested 606038032Speter by Kari Hurtta. 606138032Speter If a sequence or switch map lookup entry gets a tempfail but then 606238032Speter continues on to another map type, but the name is not found, 606338032Speter return a temporary failure from the sequence or switch map. 606438032Speter For example, if hosts search ``dns files'' and DNS fails 606538032Speter with a tempfail, the hosts map will go on and search files, 606638032Speter but if it fails the whole thing should be a tempfail, not 606738032Speter a permanent (host unknown) failure, even though that is the 606838032Speter failure in the hosts.files map. This error caused hard 606938032Speter bounces when it should have requeued. 607038032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 607190792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 607238032Speter working properly due to excessive paranoia.

Pointed out by Allan Johannesen of WPI. 610438032Speter Config files that had no AliasFile definition were defaulting to 610538032Speter using /etc/aliases; this caused problems with nullclient 610638032Speter configurations.

Fix from Brian Coan of the 613838032Speter Association for Progressive Communications. 613938032Speter If MinQueueAge was set and a message was considered but not run 614038032Speter during a queue run and the Timeout.queuereturn interval was 614138032Speter reached, a "timed out" error message would be returned that 614238032Speter didn't include the failed address (and claimed to be a warning 614338032Speter even though it was fatal). The fix is to not return such 614438032Speter messages until they are actually tried, i.e., in the next 614538032Speter MinQueueAge interval.

From Tom Moore of AT&T GIS. 620238032Speter Shorten parameters passed to syslog() in some contexts to avoid a 620338032Speter bug in many vendors' implementations of that routine. Although 620438032Speter this isn't really a bug in sendmail per se, and my solution 620538032Speter has to assume that syslog() has at least a 1K buffer size 620638032Speter internally (I know some vendors have shortened this 620738032Speter dramatically -- they're on their own), sendmail is a popular 620838032Speter target. Also, limit the size of %s arguments in sprintf. 620938032Speter These both have possible security implications. Solutions 621038032Speter suggested by Casper Dik of Sun's Network Security Group 621138032Speter (Holland), Mark Seiden, and others. 621238032Speter Fix a problem that might cause a non-standard -B (body type) 621338032Speter parameter to be passed to the next server with undefined 621438032Speter results.

Robert 622238032Speter Elz. 622338032Speter Avoid some possible null pointer dereferences. Fixes from Randy 622438032Speter Martin <WOLF@CLEMSON.EDU> 622538032Speter When sendmail starts up on systems that have no fully qualified 622638032Speter domain name (FQDN) anywhere in the first matching host map 622738032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 622838032Speter sendmail would sleep to try to find a FQDN, which it really 622938032Speter really needs. This has been changed to fall through to the 623038032Speter next map type if it can't find a FQDN -- i.e., if the hosts 623138032Speter file doesn't have a FQDN, it will try dns even though the 623238032Speter short name was found in /etc/hosts. This is probably a crock, 623338032Speter but many people have hosts files without FQDNs. Remember: 623438032Speter domain names are your friends. 623538032Speter Log a high-priority message if you can't find your FQDN during startup. 623638032Speter Suggested by Simon Barnes of Schlumberger Limited. 623738032Speter When using Hesiod, initialize it early to improve error reporting. 623838032Speter Patch from Don Lewis of Silicon Systems, Inc. 623938032Speter Apparently at least some versions of Linux have a 90 !minute!

This can 636238032Speter result in an extra 60 second delay on startup if your system 636338032Speter hostname (as returned by hostname(1)) has no dot and no names 636438032Speter listed in /etc/hosts or your NIS map have a dot. 636538032Speter Check for proper domain name on HELO and EHLO commands per 636638032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 636738032Speter of Michigan Technological University. 636838032Speter Relax chownsafe rules slightly -- old version said that if you 636938032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 637038032Speter if fpathconf returned EINVAL or ENOSYS), assume that 637138032Speter chown is not safe. The new version falls back to whether 637238032Speter you are on a BSD system or not. This is important for 637338032Speter SunOS, which apparently always returns one of those 637438032Speter error codes. This impacts whether you can mail to files 637538032Speter or not. 637638032Speter Syntax errors such as unbalanced parentheses in the configuration 637738032Speter file could be omitted if you had "Oem" prior to the 637838032Speter syntax error in the config file. Change to always print 637938032Speter the error message. It was especially weird because it 638038032Speter would cause a "warning" message to be sent to the Postmaster 638138032Speter for every message sent (but with no transcript). Problem 638238032Speter noted by Gregory Paris of Motorola. 638338032Speter Rewrite collect and putbody to handle full 8-bit data, including 638438032Speter zero bytes. These changes are internally extensive, but 638538032Speter should have minimal impact on external function. 638638032Speter Allow full words for option names -- if the option letter is 638738032Speter (apparently) a space, then take the word following -- e.g., 638838032Speter O MatchGECOS=TRUE 638938032Speter The full list of old and new names is as follows: 639038032Speter 7 SevenBitInput 639138032Speter 8 EightBitMode 639238032Speter A AliasFile 639338032Speter a AliasWait 639438032Speter B BlankSub 639538032Speter b MinFreeBlocks/MaxMessageSize 639638032Speter C CheckpointInterval 639738032Speter c HoldExpensive 639838032Speter D AutoRebuildAliases 639938032Speter d DeliveryMode 640038032Speter E ErrorHeader 640138032Speter e ErrorMode 640238032Speter f SaveFromLine 640338032Speter F TempFileMode 640438032Speter G MatchGECOS 640538032Speter H HelpFile 640638032Speter h MaxHopCount 640738032Speter i IgnoreDots 640838032Speter I ResolverOptions 640938032Speter J ForwardPath 641038032Speter j SendMimeErrors 641138032Speter k ConnectionCacheSize 641238032Speter K ConnectionCacheTimeout 641338032Speter L LogLevel 641438032Speter l UseErrorsTo 641538032Speter m MeToo 641638032Speter n CheckAliases 641738032Speter O DaemonPortOptions 641838032Speter o OldStyleHeaders 641938032Speter P PostmasterCopy 642038032Speter p PrivacyOptions 642138032Speter Q QueueDirectory 642238032Speter q QueueFactor 642338032Speter R DontPruneRoutes 642438032Speter r, T Timeout 642538032Speter S StatusFile 642638032Speter s SuperSafe 642738032Speter t TimeZoneSpec 642838032Speter u DefaultUser 642938032Speter U UserDatabaseSpec 643043730Speter V FallbackMXHost 643138032Speter v Verbose 643238032Speter w TryNullMXList 643338032Speter x QueueLA 643438032Speter X RefuseLA 643538032Speter Y ForkEachJob 643638032Speter y RecipientFactor 643738032Speter z ClassFactor 643838032Speter Z RetryFactor 643938032Speter The old macros that passed information into sendmail have 644038032Speter been changed to options; those correspondences are: 644138032Speter $e SmtpGreetingMessage 644238032Speter $l UnixFromLine 644338032Speter $o OperatorChars 644438032Speter $q (deleted -- not necessary) 644538032Speter To avoid possible problems with an older sendmail, 644638032Speter configuration level 6 is accepted by this version of 644738032Speter sendmail; any config file using the new names should 644838032Speter specify "V6" in the configuration. 644938032Speter Change address parsing to properly note that a phrase before a 645038032Speter colon and a trailing semicolon are essentially the same 645138032Speter as text outside of angle brackets (i.e., sendmail should 645238032Speter treat them as comments). This is to handle the 645338032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 645438032Speter assume that ``group name:'' is a comment on the first 645538032Speter address and the ``;'' is a comment on the last address). 645638032Speter This requires config file support to get right. It does 645738032Speter understand that :: is NOT this syntax, and can be turned 645838032Speter off completely by setting the ColonOkInAddresses option. 645938032Speter Level 6 config files added with new mailer flags: 646038032Speter A Addresses are aliasable. 646138032Speter i Do udb rewriting on envelope as well as header 646238032Speter sender lines. Applies to the from address mailer 646338032Speter flags rather than the recipient mailer flags. 646438032Speter j Do udb rewriting on header recipient addresses. 646538032Speter Applies to the sender mailer flags rather than the 646638032Speter recipient mailer flags. 646738032Speter k Disable check for loops when doing HELO command. 646838032Speter o Always run as the mail recipient, even on local 646938032Speter delivery. 647038032Speter w Check for an /etc/passwd entry for this user. 647138032Speter 5 Pass addresses through ruleset 5. 647238032Speter : Check for :include: on this address. 647338032Speter | Check for |program on this address. 647438032Speter / Check for /file on this address. 647538032Speter @ Look up sender header addresses in the user 647638032Speter database. Applies to the mailer flags for the 647738032Speter mailer corresponding to the envelope sender 647838032Speter address, rather than to recipient mailer flags. 647938032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 648038032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 648138032Speter mailers, and the ColonOkInAddresses option. 648238032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 648338032Speter John Beck of Hewlett-Packard, who generously contributed 648438032Speter their implementation to me, which I then didn't use (see 648538032Speter mime.c for an explanation of why). This adds the 648638032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 648738032Speter to control handling of 8-bit data. These have to cope with 648838032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 648938032Speter 8-bit data that is entered without declaring it as 8-bit 649038032Speter MIME -- technically this is illegal according to the 649138032Speter specs) and labelled 8-bit data (that is, it was declared 649238032Speter as 8BITMIME in the ESMTP session or by using the 649338032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 649438032Speter set then 8-bit data is sent to non-8BITMIME machines 649538032Speter instead of converting to 7 bit (essentially using 649638032Speter just-send-8 semantics). The values for EightBitMode are: 649738032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 649838032Speter any necessary conversion of 8BITMIME to 7BIT 649938032Speter (essentially, the full MIME option). 650038032Speter p pass unlabelled 8-bit input, but convert labelled 650138032Speter 8BITMIME input to 7BIT as required (default). 650238032Speter s strict adherence: reject unlabelled 8-bit input, 650338032Speter convert 8BITMIME to 7BIT as required. The F=8 650438032Speter flag is ignored. 650538032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 650638032Speter the setting of F=8. 650738032Speter Add new internal class 'n', which is the set of MIME Content-Types 650838032Speter which can not be 8 to 7 bit encoded because of other 650938032Speter considerations. Types "multipart/*" and "message/*" are 651038032Speter never directly encoded (although their components can be). 651138032Speter Add new internal class 's', which is the set of subtypes of the 651238032Speter MIME message/* content type that can be treated as though 651338032Speter they are an RFC822 message. It is predefined to have 651438032Speter "rfc822". Suggested By Kari Hurtta. 651538032Speter Add new internal class 'e'. This is the set of MIME 651638032Speter Content-Transfer-Encodings that can be converted to 651738032Speter a seven bit format (Quoted-Printable or Base64). It is 651838032Speter preinitialized to contain "7bit", "8bit", and "binary". 651938032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 652038032Speter short name) to set the default character set to use in the 652138032Speter Content-Type: header when doing encoding of an 8-bit message 652238032Speter which isn't marked as MIME into MIME format. If the C= 652338032Speter parameter is set on the Envelope From address, use that as 652438032Speter the default encoding; else use the DefaultCharSet option. 652538032Speter If neither is set, it defaults to "unknown-8bit" as 652638032Speter suggested by RFC 1428 section 3. 652738032Speter Allow ``U=user:group'' field in mailer definition to set a default 652838032Speter user and group that a mailer will be executed as. This 652938032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 653038032Speter also set, it is the uid/gid that will always be used (that 653138032Speter is, the controlling address is ignored). The values may be 653238032Speter numeric or symbolic; if only a symbolic user is given (no 653338032Speter group) that user's default group in the passwd file is used 653438032Speter as the group. Based on code donated by Chip Rosenthal of 653538032Speter Unicom. 653638032Speter Allow `u' option to also accept user:group as a value, in the same 653738032Speter fashion as the U= mailer option. 653838032Speter Add the symbolic time zone name in the Arpanet format dates (as 653938032Speter a comment). This adds a new compile-time configuration 654038032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 654138032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 654238032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 654338032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 654438032Speter timezone()), or TZ_NONE (don't include the comment). Code 654538032Speter from Chip Rosenthal. 654638032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 654738032Speter For example, 654838032Speter O Timeout.helo = 2m 654938032Speter There are also two new suboptions "queuereturn" and 655038032Speter "queuewarn"; these subsume the old T option. Thus, to 655138032Speter set them both the preferred new syntax is 655238032Speter O Timeout.queuereturn = 5d 655338032Speter O Timeout.queuewarn = 4h 655438032Speter Sort queue by host name instead of by message priority if the 655538032Speter QueueSortOrder option (no short name) is set is set to 655638032Speter ``host''. This makes better use of the connection cache, 655738032Speter but may delay more ``interactive'' messages behind large 655838032Speter backlogs under some circumstances. This is probably a 655938032Speter good option if you have high speed links or don't do lots 656038032Speter of ``batch'' messages, but less good if you are using 656138032Speter something like PPP on a 14.4 modem. Based on code 656238032Speter contributed by Roy Mongiovi of Georgia Tech (my main 656338032Speter contribution was to make it configurable). 656438032Speter Save i-number of df file in qf file to simplify rebuilding of queue 656538032Speter after disastrous disk crash. Suggested by Kyle Jones of 656638032Speter UUNET; closely based on code from KJS DECWRL code written 656738032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 656838032Speter are NOT back compatible with 8.6 -- that is, you can convert 656938032Speter from 8.6 to 8.7, but not the other direction. 657038032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 657138032Speter route-addrs in envelopes; this is because in some cases 657238032Speter they can be sent to the shell, which interprets them as 657338032Speter I/O redirection. 657438032Speter Don't include error file (option E) with return-receipts; this 657538032Speter can be confusing. 657638032Speter Don't send "Warning: cannot send" messages to owner-* or 657738032Speter *-request addresses. Suggested by Christophe Wolfhugel 657838032Speter of the Institut Pasteur, Paris. 657938032Speter Allow -O command line flag to set long form options. 658038032Speter Add "MinQueueAge" option to set the minimum time between attempts 658138032Speter to run the queue. For example, if the queue interval 658238032Speter (-q value) is five minutes, but the minimum queue age 658338032Speter is fifteen minutes, jobs won't be tried more often than 658438032Speter once every fifteen minutes. This can be used to give 658538032Speter you more responsiveness if your delivery mode is set to 658638032Speter queue-only. 658738032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 658838032Speter :include: and .forward files. 658938032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 659038032Speter key field name, the value field name, and the field 659138032Speter delimiter. The field delimiter can be a single character 659238032Speter or the sequence "\t" or "\n" for tab or newline. 659338032Speter These are for use by NIS+ and similar access methods. 659438032Speter Change maps to always strip quotes before lookups; the -q flag 659543730Speter turns off this behavior. Suggested by Motonori Nakamura. 659638032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 659738032Speter key and value field names respectively. Code donated by 659838032Speter Sun Microsystems. 659938032Speter Add "hesiod" map class. The "file name" is used as the 660038032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 660138032Speter first value found for the match. Code donated by Scott 660238032Speter Hutton of Indiana University. 660338032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 660438032Speter specify the name of the property that is searched as the 660538032Speter key and a -v flag to specify the name of the property that 660638032Speter is returned as the value (defaults to "members"). The 660738032Speter default map is "/aliases". Some code based on code 660838032Speter contributed by Robert La Ferla of Hot Software. 660938032Speter Add "text" map class. This does slow, linear searches through 661038032Speter text files. The -z flag specifies a column delimiter 661138032Speter (defaults to any sequence of white space), the -k flag 661238032Speter sets the key column number, and the -v flag sets the 661338032Speter value column number. Lines beginning with `#' are treated 661438032Speter as comments. 661538032Speter Add "program" map class to execute arbitrary programs. The search 661638032Speter key is presented as the last argument; the output is one 661738032Speter line read from the programs standard output. Exit statuses 661838032Speter are from sysexits.h. 661938032Speter Add "sequence" map class -- searches maps in sequence until it 662038032Speter finds a match. For example, the declarations: 662138032Speter Kmap1 ... 662238032Speter Kmap2 ... 662338032Speter Kmapseq sequence map1 map2 662438032Speter defines a map "mapseq" that first searches map1; if the 662538032Speter value is found it is returned immediately, otherwise 662638032Speter map2 is searched and the value returned. 662738032Speter Add "switch" map class. This is much like "sequence" except that 662838032Speter the ordering is fetched from an external file, usually 662938032Speter the system service switch. The parameter is the name of 663038032Speter the service to switch on, and the maps that it will use 663138032Speter are the name of the switch map followed by ".service_type". 663238032Speter For example, if the declaration of the map is 663338032Speter Ksample switch hosts 663438032Speter and the system service switch specifies that hosts are 663538032Speter looked up using dns and nis in that order, then this is 663638032Speter equivalent to 663738032Speter Ksample sequence sample.dns sample.nis 663838032Speter The subordinate maps (sample.*) must already be defined. 663938032Speter Add "user" map class -- looks up users using getpwnam. Takes a 664038032Speter "-v field" flag on the definition that tells what passwd 664138032Speter entry to return -- legal values are name, passwd, uid, gid, 664238032Speter gecos, dir, and shell. Generally expected to be used with 664338032Speter the -m (matchonly) flag. 664438032Speter Add "bestmx" map class -- returns the best MX value for the host 664538032Speter listed as the value. If there are several "best" MX records 664638032Speter for this host, one will be chosen at random. 664738032Speter Add "userdb" map class -- looks up entries in the user database. 664838032Speter The "file name" is actually the tag that will be used, 664938032Speter typically "mailname". If there are multiple entries 665038032Speter matching the name, the one chosen is undefined. 665138032Speter Add multiple queue timeouts (both return and warning). These are 665238032Speter set by the Precedence: or Priority: header fields to one of 665338032Speter three values. If a Priority: is set and has value "normal", 665464562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 665538032Speter used. If no priority is set, the Precedence: is consulted; 665638032Speter if negative, non-urgent timeouts are used; if greater than 665738032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 665838032Speter are used. The timeouts are set by setting the six timeouts 665938032Speter queue{warn,return}.{urgent,normal,non-urgent}. 666038032Speter Fix problem when a mail address is resolved to a $#error mailer 666138032Speter with a temporary failure indication; it works in SMTP, 666238032Speter but when delivering locally the mail is silently discarded. 666338032Speter This patch, from Kyle Jones of UUNET, bounces it instead 666438032Speter of queueing it (queueing is very hard). 666538032Speter When using /etc/hosts or NIS-style lookups, don't assume that 666638032Speter the first name in the list is the best one -- instead, 666738032Speter search for the first one with a dot. For example, if 666838032Speter an /etc/hosts entry reads 666938032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 667038032Speter this change will use the second name as the canonical 667138032Speter machine name instead of the initial, unqualified name. 667238032Speter Change dequote map to replace spaces in quoted text with a value 667338032Speter indicated by the -s flag on the dequote map definition. 667438032Speter For example, ``Mdequote dequote -s_'' will change 667538032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 667638032Speter quoted (because of the space character). Suggested by Dan 667738032Speter Oscarsson for use in X.400 addresses. 667838032Speter Implement long macro names as ${name}; long class names can 667938032Speter be similarly referenced as $={name} and $~{name}. 668038032Speter Definitions are (e.g.) ``D{name}value''. Names that have 668138032Speter a leading lower case letter or punctuation characters are 668238032Speter reserved for internal use by sendmail; i.e., config files 668338032Speter should use names that begin with a capital letter. Based 668438032Speter on code contributed by Dan Oscarsson. 668538032Speter Fix core dump if getgrgid returns a null group list (as opposed 668638032Speter to an empty group list, that is, a pointer to a list 668738032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 668838032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 668938032Speter failed, it called syserr which called newstr which called 669038032Speter xalloc.... The newstr is now avoided for "panic" messages. 669138032Speter Reported by Stuart Kemp of James Cook University. 669238032Speter Improve connection cache timeouts; previously, they were not even 669338032Speter checked if you were delivering to anything other than an 669438032Speter IPC-connected host, so a series of (say) local mail 669538032Speter deliveries could cause cached connections to be open 669638032Speter much longer than the specified timeout. 669738032Speter If an incoming message exceeds the maximum message size, stop 669838032Speter writing the incoming bytes to the queue data file, since 669938032Speter this can fill your mqueue partition -- this is a possible 670038032Speter denial-of-service attack. 670138032Speter Don't reject all numeric local user names unless HESIOD is 670238032Speter defined. It turns out that Posix allows all-numeric 670338032Speter user names. Fix from Tony Sanders of BSDI. 670438032Speter Add service switch support. If the local OS has a service 670538032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 670638032Speter on DEC systems) that will be used; otherwise, it falls back 670738032Speter to using a local mechanism based on the ServiceSwitchFile 670838032Speter option (default: /etc/service.switch). For example, if the 670938032Speter service switch lists "files" and "nis" for the aliases 671038032Speter service, that will be the default lookup order. the "files" 671138032Speter ("local" on DEC) service type expands to any alias files 671238032Speter you listed in the configuration file, even if they aren't 671338032Speter actually file lookups. 671438032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 671538032Speter variable which tells whether or not DNS should be considered 671638032Speter canonical. This is now determined based on whether or not 671738032Speter "dns" is in the service list for "hosts". 671838032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 671938032Speter Status Notifications). DSN notifications override 672038032Speter Return-Receipt-To: headers, which are bogus anyhow -- 672138032Speter support for them has been removed. 672238032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 672338032Speter definitions to define the types used in DSN returns for 672438032Speter MTA names, addresses, and diagnostics respectively. 672538032Speter Extend heuristic to force running in ESMTP mode to look for the 672638032Speter five-character string "ESMTP" anywhere in the 220 greeting 672738032Speter message (not just the second line). This is to provide 672838032Speter better compatibility with other ESMTP servers. 672938032Speter Print sequence number of job when running the queue so you can 673038032Speter easily see how much progress you have made. Suggested 673138032Speter by Peter Wemm of DIALix. 673238032Speter Map newlines to spaces in logged message-ids; some versions of 673338032Speter syslog truncate the rest of the line after newlines. 673438032Speter Suggested by Fletcher Mattox of U. Texas. 673538032Speter Move up forking for job runs so that if a message is split into 673638032Speter multiple envelopes you don't get "fork storms" -- this 673738032Speter also improves the connection cache utilization. 673838032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 673938032Speter the purposes of refusing to send error returns. Suggested 674038032Speter by Motonori Nakamura of Ritsumeikan University. 674138032Speter Relax rules on when a file can be written when referenced from 674238032Speter the aliases file: use the default uid/gid instead of the 674338032Speter real uid/gid. This allows you to create a file owned by 674438032Speter and writable only by the default uid/gid that will work 674590792Sgshapiro all the time (without having the set-user-ID bit set). Change 674638032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 674738032Speter Microsystems. 674838032Speter Add "DialDelay" option (no short name) to provide an "extra" 674938032Speter delay for dial on demand systems. If this is non-zero 675038032Speter and a connect fails, sendmail will wait this long and 675138032Speter then try again. If it takes longer than the kernel 675238032Speter timeout interval to establish the connection, this 675338032Speter option can give the network software time to establish 675438032Speter the link. The default units are seconds. 675538032Speter Move logging of sender information to be as early as possible; 675638032Speter previously, it could be delayed a while for SMTP mail 675738032Speter sent to aliases. Suggested by Brad Knowles of the 675838032Speter Defense Information Systems Agency. 675938032Speter Call res_init() before setting RES_DEBUG; this is required by 676038032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 676138032Speter the National Computer Security Center. 676238032Speter Add xdelay= field in logs -- this is a transaction delay, telling 676338032Speter you how long it took to deliver to this address on the 676438032Speter last try. It is intended to be used for sorting mailing 676538032Speter lists to favor "quick" addresses. Provided for use by 676638032Speter the mailprio scripts (see below). 676738032Speter If a map cannot be opened, and that map is non-optional, and 676838032Speter an address requires that map for resolution, queue the 676938032Speter map instead of bouncing it. This involves creating a 677038032Speter pseudo-class of maps called "bogus-map" -- if a required 677138032Speter map cannot be opened, the class is changed to bogus-map; 677238032Speter all queries against bogus-map return "tempfail". The 677338032Speter bogus-map class is not directly accessible. A sample 677438032Speter implementation was donated by Jem Taylor of Glasgow 677538032Speter University Computing Service. 677638032Speter Fix a possible core dump when mailing to a program that talks 677738032Speter SMTP on its standard input. Fix from Keith Moore of 677838032Speter the University of Kentucky. 677938032Speter Make it possible to resolve filenames to $#local $: @ /filename; 678038032Speter previously, the "@" would cause it to not be recognized 678138032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 678238032Speter Accept a -1 signal to re-exec the daemon. This only works if 678338032Speter argv[0] is a full path to sendmail. 678438032Speter Fix bug in "addr=..." field in O option on little-endian machines 678538032Speter -- the network number wasn't being converted to network 678638032Speter byte order. Patch from Kurt Lidl of Pix Technologies 678738032Speter Corporation. 678838032Speter Pre-initialize the resolver early on; this is to avoid a bug with 678938032Speter BIND 4.9.3 that can cause the _res.retry field to get 679038032Speter reset to zero, causing all name server lookups to time 679138032Speter out. Fix from Matt Day of Artisoft. 679238032Speter Restore T line (trusted users) in config file -- but instead of 679338032Speter locking out the -f flag, they just tell whether or not 679438032Speter an X-Authentication-Warning: will be added. This really 679538032Speter just creates new entries in class 't', so "Ft/file/name" 679638032Speter can be used to read trusted user names from a file. 679738032Speter Trusted users are also allowed to execute programs even 679838032Speter if they have a shell that isn't in /etc/shells. 679938032Speter Improve NEWDB alias file rebuilding so it will create them 680038032Speter properly if they do not already exist. This had been 680138032Speter a MAYBENEXTRELEASE feature in 8.6.9. 680238032Speter Check for @:@ entry in NIS maps before starting up to avoid 680338032Speter (but not prevent, sigh) race conditions. This ought to 680438032Speter be handled properly in ypserv, but isn't. Suggested by 680538032Speter Michael Beirne of Motorola. 680638032Speter Refuse connections if there isn't enough space on the filesystem 680738032Speter holding the queue. Contributed by Robert Dana of Wolf 680838032Speter Communications. 680938032Speter Skip checking for directory permissions in the path to a file 681038032Speter when checking for file permissions iff setreuid() 681138032Speter succeeded -- it is unnecessary in that case. This avoids 681238032Speter significant performance problems when looking for .forward 681338032Speter files. Based on a suggestion by Win Bent of USC. 681438032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 681538032Speter arbitrary ruleset number assigned or "Sname = integer" 681638032Speter to assign a specific ruleset number. Reference is 681738032Speter $>name_or_number. Names can be composed of alphas, digits, 681838032Speter underscore, or hyphen (first character must be non-numeric). 681938032Speter Allow -o flag on AliasFile lines to make the alias file optional. 682038032Speter From Bryan Costales of ICSI. 682138032Speter Add NoRecipientAction option to handle the case where there is 682238032Speter no legal recipient header in the message. It can take 682338032Speter on values: 682438032Speter None Leave the message as is. The 682538032Speter message will be passed on even 682638032Speter though it is in technically 682738032Speter illegal syntax. 682838032Speter Add-To Add a To: header with any 682938032Speter recipients that it can find from 683038032Speter the envelope. This risks exposing 683138032Speter Bcc: recipients. 683238032Speter Add-Apparently-To Add an Apparently-To: header. This 683338032Speter has almost no redeeming social value, 683438032Speter and is provided only for back 683538032Speter compatibility. 683638032Speter Add-To-Undisclosed Add a header reading 683738032Speter To: undisclosed-recipients:; 683838032Speter which will have the effect of 683938032Speter making the message legal without 684038032Speter exposing Bcc: recipients. 684138032Speter Add-Bcc To add an empty Bcc: header. 684238032Speter There is a chance that mailers down 684338032Speter the line will delete this header, 684438032Speter which could cause exposure of Bcc: 684538032Speter recipients. 684638032Speter The default is NoRecipientAction=None. 684738032Speter Truncate (rather than delete) Bcc: lines in the header. This 684838032Speter should prevent later sendmails (at least, those that don't 684938032Speter themselves delete Bcc:) from considering this message to 685038032Speter be non-conforming -- although it does imply that non-blind 685138032Speter recipients can see that a Bcc: was sent, albeit not to whom. 685238032Speter Add SafeFileEnvironment option. If declared, files named as delivery 685338032Speter targets must be regular files in addition to the regular 685438032Speter checks. Also, if the option is non-null then it is used as 685538032Speter the name of a directory that is used as a chroot(2) 685638032Speter environment for the delivery; the file names listed in an 685738032Speter alias or forward should include the name of this root. 685838032Speter For example, if you run with 685938032Speter O SafeFileEnvironment=/arch 686038032Speter then aliases should reference "/arch/rest/of/path". If a 686138032Speter value is given, sendmail also won't try to save to 686238032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 686338032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 686438032Speter Support -A flag for alias files; this will comma concatenate like 686538032Speter entries. For example, given the aliases: 686638032Speter list: member1 686738032Speter list: member2 686838032Speter and an alias file declared as: 686938032Speter OAhash:-A /etc/aliases 687038032Speter the final alias inserted will be "list: member1,member2"; 687138032Speter without -A you will get an error on the second and subsequent 687238032Speter alias for "list". Contributed by Bryan Costales of ICSI. 687338032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 687438032Speter Fix a problem that could cause very long addresses to core dump in 687538032Speter some special circumstances. Problem pointed out by Allan 687638032Speter Johannesen. 687738032Speter (Internal change.) Change interface to expand() (macro expansion) 687838032Speter to be simpler and more consistent. 687938032Speter Delete check for funny qf file names. This didn't really give 688038032Speter any extra security and caused some people some problems. 688138032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 688238032Speter at compile time.) Suggested by Kyle Jones of UUNET. 688338032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 688438032Speter merge with DSN code; this is simpler and more consistent. 688538032Speter This may affect some people who have written their own 688638032Speter checkcompat() routine. 688738032Speter (Internal change.) Eliminate `D' line in qf file. The df file 688838032Speter is now assumed to be the same name as the qf file (with 688938032Speter the `q' changed to a `d', of course). 689038032Speter Avoid forking for delivery if all recipient mailers are marked as 689138032Speter "expensive" -- this can be a major cost on some systems. 689238032Speter Essentially, this forces sendmail into "queue only" mode 689338032Speter if all it is going to do is queue anyway. 689438032Speter Avoid sending a null message in some rather unusual circumstances 689538032Speter (specifically, the RCPT command returns a temporary 689638032Speter failure but the connection is lost before the DATA 689738032Speter command). Fix from Scott Hammond of Secure Computing 689838032Speter Corporation. 689938032Speter Change makesendmail to use a somewhat more rational naming scheme: 690038032Speter Makefiles and obj directories are named $os.$rel.$arch, 690138032Speter where $os is the operating system (e.g., SunOS), $rel is 690238032Speter the release number (e.g., 5.3), and $arch is the machine 690338032Speter architecture (e.g., sun4). Any of these can be omitted, 690438032Speter and anything after the first dot in a release number can 690538032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 690638032Speter version used $os.$arch.$rel and was rather less general. 690738032Speter Change makesendmail to do a "make depend" in the target directory 690838032Speter when it is being created. This involves adding an empty 690938032Speter "depend:" entry in most Makefiles. 691038032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 691138032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 691238032Speter of the Finnish Meteorological Institute. 691338032Speter Fix problem that could cause multiple responses to DATA command 691438032Speter on header syntax errors (e.g., lines beginning with colons). 691538032Speter Problem noted by Jens Thomassen of the University of Oslo. 691638032Speter Don't let null bytes in headers cause truncation of the rest of 691738032Speter the header. 691838032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 691938032Speter Increase timeouts on message data puts to allow time for receivers 692038032Speter to canonify addresses in headers on the fly. This is still 692138032Speter a rather ugly heuristic. From Motonori Nakamura. 692238032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 692338032Speter records are not used when canonifying names, and when MX 692438032Speter lookups are done for addressing they must be fully 692538032Speter qualified. This is useful if you have a wildcard MX record, 692638032Speter although it may cause other problems. In general, don't use 692738032Speter wildcard MX records. Patch from Motonori Nakamura. 692838032Speter Eliminate default two-line SMTP greeting message. Instead of 692938032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 693038032Speter is added between the first and second word of the first 693138032Speter line of the greeting message (i.e., immediately after the 693238032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 693338032Speter compile flag. Old sendmails won't see the ESMTP, but that's 693438032Speter acceptable because SIZE was the only useful extension that 693538032Speter old sendmails understand. 693638032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 693738032Speter invoked state dumps. From Masaharu Onishi. 693838032Speter Allow on-line comments in .forward and :include: files; they are 693938032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 694038032Speter is a space or a tab. This is intended for native 694138032Speter representation of non-ASCII sets such as Japanese, where 694238032Speter existing encodings would be unreadable or would lose 694338032Speter data -- for example, 694438032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 694538032Speter (romanized/less information) 694638032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 694738032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 694838032Speter (with MIME encoding, not human readable) 694938032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 695038032Speter (native encoding with ISO-2022-JP) 695138032Speter The last form is human readable in the Japanese environment. 695238032Speter Based on a fix from (surprise!) Motonori Nakamura. 695338032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 695438032Speter messages to that host; these are most frequently associated 695538032Speter with addresses rather than the host, with the exception of 695638032Speter 421 (service shutting down). The effect was to cause queues 695738032Speter to sometimes take an excessive time to flush. Reported by 695838032Speter Robert Sargent of Southern Geographics Technologies and 695938032Speter Eric Prestemon of American University. 696038032Speter Add Nice=N mailer option to set the niceness at which a mailer will 696138032Speter run. This is actually a relative niceness (that is, an 696238032Speter increment on the background value). 696338032Speter Log queue runs that are skipped due to high loads. They are logged 696438032Speter at LOG_INFO priority iff the log level is > 8. Contributed 696538032Speter by Bruce Nagel of Data General. 696638032Speter Allow the error mailer to accept a DSN-style error status code 696738032Speter instead of an sysexits status code in the host part. 696838032Speter Anything with a dot will be interpreted as a DSN-style code. 696938032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 697038032Speter to encode characters that might be munged by an EBCDIC system 697138032Speter in addition to the set required by RFC 1521. The additional 697238032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 697338032Speter (Think of "IBM 360" as the mnemonic for this flag.) 697438032Speter Change check for mailing to files to look for a pathname of [FILE] 697538032Speter rather than looking for the mailer named *file*. The mapping 697638032Speter of leading slashes still goes to the *file* mailer. This 697738032Speter allows you to implement the *file* mailer as a separate 697838032Speter program, for example, to insert a Content-Length: header 697938032Speter or do special security policy. However, note that the usual 698038032Speter initial checking for the file permissions is still done, and 698138032Speter the program in question needs to be very careful about how 698238032Speter it does the file write to avoid security problems. 698338032Speter Be able to read ~root/.forward even if the path isn't accessible to 698438032Speter regular users. This is disrecommended because sendmail 698538032Speter sometimes does not run as root (e.g., when an unsafe option 698638032Speter is specified on the command line), but should otherwise be 698738032Speter safe because .forward files must be owned by the user for 698838032Speter whom mail is being forwarded, and cannot be a symbolic link. 698938032Speter Suggested by Forrest Aldrich of Wang Laboratories. 699038032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 699138032Speter file. This is used for canonifying hostnames when the 699238032Speter service type is "files". 699338032Speter Implement programs on F (read class from file) line. The syntax is 699438032Speter Fc|/path/to/program to read the output from the program 699538032Speter into class "c". 699638032Speter Probe the network interfaces to find alternate names for this 699738032Speter host. Requires the SIOCGIFCONF ioctl call. Code 699838032Speter contributed by SunSoft. 699938032Speter Add "E" configuration line to set or propagate environment 700038032Speter variables into children. "E<envar>" will propagate 700138032Speter the named variable from the environment when sendmail 700238032Speter was invoked into any children it calls; "E<envar>=<value>" 700338032Speter sets the named variable to the indicated value. Any 700438032Speter variables not explicitly named will not be in the child 700538032Speter environment. However, sendmail still forces an 700638032Speter "AGENT=sendmail" environment variable, in part to enforce 700738032Speter at least one environment variable, since many programs and 700838032Speter libraries die horribly if this is not guaranteed. 700938032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 701038032Speter alias databases -- new algorithm looks for the substring 701138032Speter "/yp/" in the file name. This is more portable and involves 701238032Speter less overhead. Suggested by Motonori Nakamura. 701338032Speter Dynamically allocate the queue work list so that you don't lose 701438032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 701538032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 701638032Speter should not need to be changed) and the MaxQueueRunSize option, 701738032Speter which is the absolute maximum number of jobs that will ever 701838032Speter be handled in a single queue run. Based on code contributed 701938032Speter by Brian Coan of the Institute for Global Communications. 702038032Speter Log message when a message is dropped because it exceeds the maximum 702138032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 702238032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 702338032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 702438032Speter of Mark G. Thomas Consulting. 702538032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 702638032Speter OS-dependent defines). The old semantic of -d0.1 to not 702738032Speter run the daemon in background has been moved to -d99.100, 702838032Speter and the old 52.5 flag (to avoid disconnect() from closing 702938032Speter all output files) has been moved to 52.100. This makes 703038032Speter things more consistent (flags below .100 don't change 703138032Speter semantics) and separates out the backgrounding so that 703238032Speter it doesn't happen automatically on other unrelated debugging 703338032Speter flags. 703438032Speter If -t is used but no addresses are found in the header, give an 703538032Speter error message rather than just doing nothing. Fix from 703638032Speter Motonori Nakamura. 703738032Speter On systems (like SunOS) where the effective gid is not necessarily 703838032Speter included in the group list returned by getgroups(), the 703938032Speter `restrictmailq' option could sometimes cause an authorized 704038032Speter user to not be able to use `mailq'. Fix from Charles Hannum 704138032Speter of MIT. 704238032Speter Allow symbolic service names for [IPC] mailers. Suggested by 704338032Speter Gerry Magennis of Logica International. 704438032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 704538032Speter when running DNS. For example, if the name FTP.Foo.ORG is 704638032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 704738032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 704838032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 704938032Speter This is technically illegal under RFC 822 and 1123, but the 705038032Speter IETF is moving toward legalizing it. Note that turning on 705138032Speter this option is not sufficient to guarantee that a downstream 705238032Speter neighbor won't rewrite the address for you. 705338032Speter Add "-m" flag to makesendmail script -- this tells you what object 705438032Speter directory and Makefile it will use, but doesn't actually do 705538032Speter the make. 705638032Speter Do some additional checking on the contents of the qf file to try 705738032Speter to detect attacks against the qf file. In particular, 705838032Speter abort on any line beginning "From ", and add an "end of 705938032Speter file" line -- any data after that line is prohibited. 706038032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 706138032Speter choices. This can be overridden in the Makefile by using 706238032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 706338032Speter (to the extent that we know it) or by defining 706438032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 706538032Speter sendmail 8 to have more consistent installation instructions. 706638032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 706738032Speter of Sun Microsystems. 706838032Speter Improved symbol table hash function from Eric Wassenaar. This one 706938032Speter is at least 50% faster. 707038032Speter Fix problem that didn't notice that timeout on file open was a 707138032Speter transient error. Fix from Larry Parmelee of Cornell 707238032Speter University. 707338032Speter Allow comments (lines beginning with a `#') in files read for 707438032Speter classes. Suggested by Motonori Nakamura. 707538032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 707638032Speter of dropping out entirely. This makes testing some of the 707738032Speter name server lookups easier to deal with when there are 707838032Speter hung servers. From Motonori Nakamura. 707938032Speter Add new ${opMode} macro that is set to the current operation mode 708038032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 708138032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 708238032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 708338032Speter Kind of like queue-only mode (Odq) except it tries to avoid 708438032Speter any external service requests; for dial-on-demand hosts that 708538032Speter want to minimize DNS lookups when mail is being queued. For 708638032Speter this to work you will also have to make sure that gethostbyname 708738032Speter of your local host name does not do a DNS lookup. 708838032Speter Improved handling of "out of space" conditions from John Myers of 708938032Speter Carnegie Mellon. 709038032Speter Improved security for mailing to files on systems that have fchmod(2) 709138032Speter support. 709238032Speter Improve "cannot send message for N days" message -- now says "could 709338032Speter not send for past N days". Suggested by Tom Moore of AT&T 709438032Speter Global Information Solutions. 709538032Speter Less misleading Subject: line on messages sent to postmaster only. 709638032Speter From Motonori Nakamura. 709738032Speter Avoid duplicate error messages on bad command line flags. From 709838032Speter Motonori Nakamura. 709938032Speter Better error message for case where ruleset 0 falls off the end 710038032Speter or otherwise does not resolve to a canonical triple. 710138032Speter Fix a problem that could cause multiple bounce messages if a bad 710238032Speter address was sent along with a good address to an SMTP 710338032Speter site where that SMTP site returned a 4yz code in response 710438032Speter to the final dot of the data. Problem reported by David 710538032Speter James of British Telecom. 710638032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 710738032Speter from Alexander Dupuy of System Management ARTS. 710838032Speter Delete duplicates in MX lists -- believe it or not, there are sites 710938032Speter that list the same host twice in an MX list. This deletion 711038032Speter only works on adjacent preferences, so an MX list that 711138032Speter had A=5, B=10, A=15 would leave both As, but one that had 711238032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 711338032Speter just in case there is something weird I haven't thought of. 711438032Speter Suggested by Barry Shein of Software Tool & Die. 711538032Speter SECURITY: .forward files cannot be symbolic links. If they are, 711638032Speter a bad guy can read your private files. 711738032Speter PORTABILITY FIXES: 711838032Speter Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>. 711938032Speter System V Release 4 from Motonori Nakamura of Ritsumeikan 712038032Speter University.

This means that the 713438032Speter sizeof operator returns only multiples of 8. 713538032Speter This requires adaptation of code that really 713638032Speter deals with 32 bit or 16 bit fields, such as IP 713738032Speter addresses or nameserver fields.'' 713838032Speter DG/UX 5.4.3 from Mark T.

This can 722338032Speter be used as an alternative to /bin/sh for the "prog" mailer, 722438032Speter giving the local administrator more control over what 722538032Speter programs can be run from sendmail. 722638032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 722738032Speter part of the release proper, and isn't fully supported; in 722838032Speter particular, it does not run on System V based systems and 722938032Speter never will. 723038032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 723138032Speter to allow rmail to compile on systems that don't have 723238032Speter function prototypes and systems that don't have snprintf. 723338032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 723438032Speter lists by transaction delay times so that addresses that 723538032Speter respond quickly get sent first. This is to prevent very 723638032Speter sluggish servers from delaying other peoples' mail. 723738032Speter Contributed by Tony Sanders of BSDI. 723838032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 723938032Speter of BSDI. This has a lot of comments to help people out. 724038032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 724138032Speter put this on the m4 command line. On GNU m4 (which 724238032Speter supports the __file__ primitive) you can run m4 in an 724338032Speter arbitrary directory -- use either: 724438032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 724538032Speter or 724638032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 724738032Speter On other versions of m4 that don't support __file__, you 724838032Speter can use: 724938032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 725038032Speter (Note the trailing slash on the _CF_DIR_ definition.) 725138032Speter Old versions of m4 will default to _CF_DIR_=.. for back 725238032Speter compatibility. 725338032Speter CONFIG: fix mail from <> so it will properly convert to 725438032Speter MAILER-DAEMON on local addresses. 725538032Speter CONFIG: fix code that was supposed to catch colons in host 725638032Speter names. Problem noted by John Gardiner Myers of CMU. 725738032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 725838032Speter From Paul Riddle of the University of Maryland, Baltimore 725938032Speter County. 726038032Speter CONFIG: Catch and reject "." as a host address. 726138032Speter CONFIG: Generalize domaintable to look up all domains, not 726238032Speter just unqualified ones. 726338032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 726438032Speter was never used and didn't work anyway. 726538032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 726638032Speter and d on all mailers in the UUCP class. 726738032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 726838032Speter look for an alias for "user+detail", then for "user+*", and 726938032Speter finally for "user". This is intended for forwarding mail 727038032Speter for system aliases such as root and postmaster to a 727138032Speter centralized hub. 727238032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 727338032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 727438032Speter The F=8 flag is also set on the "relay" mailer, since 727538032Speter this is expected to be another sendmail. 727638032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 727738032Speter the name of the UUCP_RELAY -- in some cases, this is the 727838032Speter wrong value (e.g., when we have local UUCP connections), 727938032Speter and this can create unreplyable addresses. From Chip 728038032Speter Rosenthal of Unicom. 728138032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 728264562Sgshapiro Received: header inserted into all messages. Suggested by 728338032Speter Gary Mills of the University of Manitoba. 728438032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 728543730Speter to get the old behavior. I did this upon observing 728638032Speter that almost everyone needed this feature, and that the 728738032Speter concept I was trying to make happen didn't work with 728838032Speter some user agents anyway. FEATURE(notsticky) still works, 728938032Speter but it is a no-op. 729038032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 729138032Speter names are sent, rather than immediately diagnosing them 729238032Speter as User Unknown. 729338032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 729438032Speter and RELAY_MAILER_ARGS to set the arguments for the 729538032Speter indicated mailers. All default to "IPC $h". Patch from 729638032Speter Larry Parmelee of Cornell University. 729738032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 729838032Speter on the client side" and F=P to get an appropriate 729938032Speter return-path. From Kimmo Suominen. 730038032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 730138032Speter as the local mailer. For addresses of the form "user+detail" 730238032Speter the "detail" part is passed to procmail via the -a flag. 730338032Speter Contributed by Kimmo Suominen. 730438032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 730538032Speter use from mailertables. This lets you execute arbitrary 730638032Speter procmail scripts. Contributed by Kimmo Suominen. 730738032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 730838032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 730938032Speter Paul Southworth of CICNet Systems Support. 731038032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 731138032Speter This causes the null return path to be rewritten as 731238032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 731338032Speter From Michael Hohmuth of Technische Universitat Dresden. 731438032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 731538032Speter list us as the best possible MX record to be treated as 731638032Speter though they were local (essentially, assume that they 731738032Speter are included in $=w). This can cause additional DNS 731838032Speter traffic, but is easier to administer if this fits your 731938032Speter local model. It does not work reliably if there are 732038032Speter multiple hosts that share the best MX preference. 732138032Speter Code contributed by John Oleynick of Rutgers. 732238032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 732338032Speter SHell) instead of /bin/sh as the program used for delivery 732438032Speter to programs. If an argument is included, it is used as 732538032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 732638032Speter assumed. 732738032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 732838032Speter size of messages to the local and procmail mailers 732938032Speter respectively. Contributed by Brad Knowles of the Defense 733038032Speter Information Systems Agency. 733138032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 733238032Speter (just like text outside of angle brackets) in order to 733338032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 733438032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 733538032Speter any real systems any more) and tweak the DOMAIN macro 733638032Speter so that it is less likely that users will accidentally use 733738032Speter the Berkeley defaults. Also, create some generic files 733838032Speter that really can be used in the real world. 733938032Speter CONFIG: Add new configuration macros to set character sets for 734038032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 734138032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 734238032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 734338032Speter The old name will still be accepted for a while at least. 734438032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 734538032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 734638032Speter As with all relays, it can be ``mailer:hostname''. Suggested 734738032Speter by Scott Hutton. 734838032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 734938032Speter by Barb Dijker of Labyrinth Computer Services. 735038032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 735138032Speter performance for large alias files, and this confused many 735238032Speter people. 735338032Speter CONFIG: Add confCF_VERSION to append local information to the 735438032Speter configuration version number displayed during SMTP startup. 735538032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 735638032Speter would only work when locally addressed. Fix from 735738032Speter Edvard Tuinder of Cistron Internet Services. 735838032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 735943730Speter "n" (CheckAliases) is set when rebuilding alias database. 736038032Speter Based on code contributed by Claude Marinier. 736138032Speter CONFIG: Allow mailertable to have values of the form 736238032Speter ``error:code message''. The ``code'' is a status code 736338032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 736438032Speter Contributed by David James <dwj@agw.bt.co.uk>. 736538032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 736638032Speter sender domains that will be replaced with the masquerade name. 736738032Speter These domains will not be treated as local, but if mail passes 736838032Speter through with sender addresses in those domains they will be 736938032Speter replaced by the masquerade name. These can also be specified 737038032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 737138032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 737238032Speter as well as the header. Substantial improvements to this 737338032Speter code were contributed by Per Hedeland. 737438032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 737538032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 737638032Speter by Kimmo Suominen. 737738032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 737838032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 737938032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 738038032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 738138032Speter UUCP addressing.

749264562Sgshapiro8.6.12/8.6.12 1995/03/28 749338032Speter Fix to IDENT code (it was getting the size of the reply buffer 749438032Speter too small, so nothing was ever accepted). Fix from several 749538032Speter people, including Allan Johannesen, Shane Castle of the 749638032Speter Boulder County Information Services, and Jeff Smith of 749738032Speter Warwick University (all arrived within a few hours of 749838032Speter each other!). 749938032Speter Fix a problem that could cause large jobs to run out of 750038032Speter file descriptors on systems that use vfork() rather 750138032Speter than fork(). 750238032Speter 750364562Sgshapiro8.6.11/8.6.11 1995/03/08 750438032Speter The ``possible attack'' message would be logged more often 750538032Speter than necessary if you are using Pine as a user agent. 750638032Speter The wrong host would be reported in the ``possible attack'' 750738032Speter message when attempted from IDENT. 750838032Speter In some cases the syslog buffer could be overflowed when 750938032Speter reporting the ``possible attack'' message. This can 751038032Speter cause denial of service attacks. Truncate the message 751138032Speter to 80 characters to prevent this problem. 751238032Speter When reading the IDENT response a loop is needed around the 751338032Speter read from the network to ensure that you don't get 751438032Speter partial lines. 751538032Speter Password entries without any shell listed (that is, a null 751638032Speter shell) wouldn't match as "ok". Problem noted by 751738032Speter Rob McMahon. 751838032Speter When running BIND 4.9.x a problem could occur because the 751938032Speter _res.options field is initialized differently than it 752038032Speter was historically -- this requires that sendmail call 752138032Speter res_init before it tweaks any bits. 752238032Speter Fix an incompatibility in openxscript() between the file open mode 752338032Speter and the stdio mode passed to fdopen. This caused UnixWare 752438032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 752538032Speter Novell Labs Europe. 752638032Speter Fix problem with static linking of local getopt routine when 752738032Speter using GNU's ld command. Fix from John Kennedy of 752838032Speter Cal State Chico. 752938032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 753238032Speter and Liudvikas Bukys. 753338032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 753438032Speter from Spider Boardman. 753538032Speter CONFIG: No changes (version number only, to keep it in sync 753638032Speter with the binaries). 753738032Speter 753864562Sgshapiro8.6.10/8.6.10 1995/02/10 753938032Speter SECURITY: Diagnose bogus values to some command line flags that 754038032Speter could allow trash to get into headers and qf files. 754138032Speter Validate the name of the user returned by the IDENT protocol. 754238032Speter Some systems that really dislike IDENT send intentionally 754338032Speter bogus information. Problem pointed out by Michael Bushnell 754438032Speter of the Free Software Foundation. Has some security 754538032Speter implications. 754638032Speter Fix a problem causing error messages about DNS problems when 754738032Speter the host name contained a percent sign to act oddly 754838032Speter because it was passed as a printf-style format string. 754938032Speter In some cases this could cause core dumps. 755038032Speter Avoid possible buffer overrun in returntosender() if error 755138032Speter message is quite long. From Fletcher Mattox of the 755238032Speter University of Texas. 755338032Speter Fix a problem that would silently drop "too many hops" error 755438032Speter messages if and only if you were sending to an alias. 755538032Speter From Jon Giltner of the University of Colorado and 755638032Speter Dan Harton of Oak Ridge National Laboratory. 755738032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 755838032Speter set and e->e_message was null. Fix from Bruce Nagel of 755938032Speter Data General. 756038032Speter Fix problem that can still cause df files to be left around 756138032Speter after "hop count exceeded" messages. Fix from Andrew 756238032Speter Chang and Shau-Ping Lo of SunSoft. 756338032Speter Fix a problem that can cause buffer overflows on very long 756438032Speter user names (as might occur if you piped to a program 756538032Speter with a lot of arguments). 756638032Speter Avoid returning an error and re-queueing if the host signature 756738032Speter is null; this can occur on addresses like ``user@.''. 756838032Speter Problem noted by Wesley Craig and the University of 756938032Speter Michigan. 757038032Speter Avoid possible calls to malloc(0) if MCI caching is turned 757138032Speter off. Bug fix from Pierre David of the Laboratoire 757238032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 757338032Speter Universite de Versailles - St Quentin, and Jacky 757438032Speter Thibault. 757538032Speter Make a local copy of the line being sent via senttolist() -- in 757638032Speter some cases, buffers could get trashed by map lookups 757738032Speter causing it to do unexpected things. This also simplifies 757838032Speter some of the map code. 757938032Speter CONFIG: No changes (version number only, to keep it in sync 758038032Speter with the binaries). 758138032Speter 758264562Sgshapiro8.6.9/8.6.9 1994/04/19 758338032Speter Do all mail delivery completely disconnected from any terminal. 758438032Speter This provides consistency with daemon delivery and 758538032Speter may have some security implications. 758638032Speter Make sure that malloc doesn't get called with zero size, 758738032Speter since that fails on some systems. Reported by Ed 758838032Speter Hill of the University of Iowa. 758938032Speter Fix multi-line values for $e (SMTP greeting message). Reported 759038032Speter by Mike O'Connor of Ford Motor Company. 759138032Speter Avoid syserr if no NIS domain name is defined, but the map it 759238032Speter is trying to open is optional. From Win Bent of USC. 759338032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 759438032Speter Hesiod support for UDB from Todd Miller of the University of 759538032Speter Colorado. Use "hesiod" as the service name in the U 759638032Speter option. 759738032Speter Fix a problem that failed to set the "authentic" host name (that 759838032Speter is, the one derived from the socket info) if you called 759938032Speter sendmail -bs from inetd. Based on code contributed by 760038032Speter Todd Miller (this problem was also reported by Guy Helmer 760138032Speter of Dakota State University). This also fixes a related 760238032Speter problem reported by Liudvikas Bukys of the University of 760338032Speter Rochester. 760438032Speter Parameterize "nroff -h" in all the Makefiles so people with 760538032Speter variant versions can use them easily. Suggested by 760638032Speter Peter Collinson of Hillside Systems. 760738032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 760838032Speter spaces between parameters instead of one. Reported by 760938032Speter Valdis Kletnieks of Virginia Tech. 761038032Speter Reduce the number of system calls during message collection by 761138032Speter using global timeouts around the collect() loop. This 761238032Speter code was contributed by Eric Wassenaar. 761338032Speter If the initial hostname name gathering results in a name 761438032Speter without a dot (usually caused by NIS misconfiguration) 761538032Speter and BIND is compiled in, directly access DNS to get 761638032Speter the canonical name. This should make life easier for 761738032Speter Solaris systems. If it still can't be resolved, and 761838032Speter if the name server is listed as "required", try again 761938032Speter in 30 seconds. If that also fails, exit immediately to 762038032Speter avoid bogus "config error: mail loops back to myself" 762138032Speter messages. 762238032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 762338032Speter message to explain how much space was available and 762438032Speter sound a bit less threatening. Suggested by Stan Janet 762538032Speter of the National Institute of Standards and Technology. 762638032Speter If mail is delivered to an alias that has an owner, deliver any 762738032Speter requested return-receipt immediately, and strip the 762838032Speter Return-Receipt-To: header from the subsequent message. 762938032Speter This prevents a certain class of denial of service 763038032Speter attack, arguably gives more reasonable semantics, and 763138032Speter moves things more towards what will probably become a 763238032Speter network standard. Suggested by Christopher Davis of 763338032Speter Kapor Enterprises. 763438032Speter Add a "noreceipts" privacy flag to turn off all return receipts 763538032Speter without recompiling. 763638032Speter Avoid printing ESMTP parameters as part of the error message 763738032Speter if there are errors during parsing. This change is 763838032Speter purely cosmetic. 763938032Speter Avoid sending out error messages during the collect phase of 764038032Speter SMTP; there is an MVS mailer from UCLA that gets 764138032Speter confused by this. Of course, I think it's their bug.... 764238032Speter Check for the $j macro getting undefined, losing a dot, or getting 764338032Speter lost from $=w in the daemon before accepting a connection; 764438032Speter if it is, it dumps state, prints a LOG_ALERT message, 764538032Speter and drops core for debugging. This is an attempt to 764638032Speter track down a bug that I thought was long since gone. 764738032Speter If you see this, please forward the log fragment to 764838032Speter sendmail@sendmail.ORG. 764938032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 765038032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 765138032Speter Wolfhugel. 765238032Speter Instead of trying to truncate the listen queue for the server 765338032Speter SMTP port when the load average is too high, just close 765438032Speter the port completely and reopen it later as needed. 765538032Speter This ensures that the other end gets a quick "connection 765638032Speter refused" response, and that the connection can be 765738032Speter recovered later. In particular, some socket emulations 765838032Speter seem to get confused if you tweak the listen queue 765938032Speter size around and can never start listening to connections 766038032Speter again. The down side is that someone could start up 766138032Speter another daemon process in the interim, so you could 766238032Speter have multiple daemons all not listening to connections; 766338032Speter this could in turn cause the sendmail.pid file to be 766438032Speter incorrect. A better approach might be to accept the 766538032Speter connection and give a 421 code, but that could break 766643730Speter other mailers in mysterious ways and have paging behavior 766738032Speter implications. 766838032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 766938032Speter set debugging on the wrong socket. From Eric Wassenaar. 767038032Speter When creating a df* temporary file, be sure you truncate any 767138032Speter existing data in the file -- otherwise system crashes 767238032Speter and the like could result in extra data being sent. 767338032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 767438032Speter doc directory. This includes some additional 767538032Speter information. 767638032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 767738032Speter of recipient envelope addresses. This should have been 767838032Speter handled by the $&h trick, but broke if people were 767938032Speter mixing domainized and UUCP addresses. They should 768038032Speter probably have converted all the way over to uucp-uudom 768138032Speter instead of uucp-{new,old}, but the failure mode was to 768238032Speter loop the mail, which was bad news. 768338032Speter Portability fixes: 768438032Speter Newer BSDI systems (several people). 768538032Speter Older BSDI systems from Christophe Wolfhugel. 768638032Speter Intergraph CLIX, from Paul Southworth of CICNet. 768738032Speter UnixWare, from Evan Champion. 768838032Speter NetBSD from Adam Glass. 768938032Speter Solaris from Quentin Campbell of the University of 769038032Speter Newcastle upon Tyne. 769138032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 769238032Speter Corporation. 769338032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 769438032Speter SunOS (it has setsid() and setvbuf() calls) from 769538032Speter Jonathan Kamens of OpenVision Technologies. 769638032Speter HP-UX from Tor Lillqvist. 769738032Speter New Files: 769838032Speter src/Makefile.CLIX 769938032Speter src/Makefile.NCR3000 770038032Speter doc/changes/Makefile 770138032Speter doc/changes/changes.me 770238032Speter doc/changes/changes.ps 770338032Speter 770464562Sgshapiro8.6.8/8.6.6 1994/03/21 770538032Speter SECURITY: it was possible to read any file as root using the 770638032Speter E (error message) option. Reported by Richard Jones; 770738032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 770838032Speter 770964562Sgshapiro8.6.7/8.6.6 1994/03/14 771038032Speter SECURITY: it was possible to get root access by using weird 771138032Speter values to the -d flag. Thanks to Alain Durand of 771238032Speter INRIA for forwarding me the notice from the bugtraq 771338032Speter list. 771438032Speter 771564562Sgshapiro8.6.6/8.6.6 1994/03/13 771638032Speter SECURITY: the ability to give files away on System V-based 771738032Speter systems proved dangerous -- don't run as the owner 771838032Speter of a :include: file on a system that allows giveaways. 771938032Speter Unfortunately, this also applies to determining a 772038032Speter valid shell. 772138032Speter IMPORTANT: Previous versions weren't expiring old connections 772238032Speter in the connection cache for a long time under some 772338032Speter circumstances. This could result in resource exhaustion, 772438032Speter both at your end and at the other end. This checks the 772538032Speter connections for timeouts much more frequently. From 772638032Speter Doug Anderson of NCSC. 772738032Speter Fix a glitch that snuck in that caused programs to be run as 772838032Speter the sender instead of the recipient if the mail was 772938032Speter from a local user to another local user. From 773038032Speter Motonori Nakamura of Kyoto University. 773138032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 773238032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 773338032Speter Bryan Costales of ICSI. 773438032Speter Change the method used to declare the "statfs" availability; 773538032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 773638032Speter tweaking in conf.c, there is a single #define called 773738032Speter SFS_TYPE which takes on one of six values (SFS_NONE 773838032Speter for no statfs availability, SFS_USTAT for the ustat(2) 773938032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 774038032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 774138032Speter statfs(2) call with the declarations in <sys/vfs.h>, 774238032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 774338032Speter Fix glitch in NetInfo support that could return garbage if 774438032Speter there was no "/locations/sendmail" property. From 774538032Speter David Meyer of the University of Virginia. 774638032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 774738032Speter to allow Linux to turn it off even though it is a 774838032Speter BSD-like system. 774938032Speter Allow setting of "ident" timeout to zero to turn off the ident 775038032Speter protocol entirely. 775138032Speter Make 7-bit stripping local to a connection (instead of to a 775238032Speter mailer); this allows you to specify that SMTP is a 775338032Speter 7-bit channel, but revert to 8-bit should it advertise 775438032Speter that it supports 8BITMIME. You still have to specify 775538032Speter mailer flag 7 to get this stripping at all. 775638032Speter Improve makesendmail script so it handles more cases automatically. 775738032Speter Tighten up restrictions on taking ownership of :include: files 775838032Speter to avoid problems on systems that allow you to give away 775938032Speter files. 776038032Speter Fix a problem that made it impossible to rebuild the alias 776138032Speter file if it was on a read-only file system. From 776238032Speter Harry Edmon of the University of Washington. 776338032Speter Improve MX randomization function. From John Gardiner Myers 776438032Speter of CMU. 776538032Speter Fix a minor glitch causing a bogus message to be printed (used 776638032Speter %s instead of %d in a printf string for the line number) 776738032Speter when a bad queue file was read. From Harry Edmon. 776838032Speter Allow $s to remain NULL on locally generated mail. I'm not 776938032Speter sure this is necessary, but a lot of people have complained 777038032Speter about it, and there is a legitimate question as to whether 777138032Speter "localhost" is legal as an 822-style domain. 777238032Speter Fix a problem with very short line lengths (mailer L= flag) in 777338032Speter headers. This causes a leading space to be added onto 777438032Speter continuation lines (including in the body!), and also 777538032Speter tries to wrap headers containing addresses (From:, To:, 777638032Speter etc) intelligently at the shorter line lengths. Problem 777738032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 777838032Speter Log the real user name when logging syserrs, since these can have 777938032Speter security implications. Suggested by several people. 778038032Speter Fix address logging of cached connections -- it used to always 778138032Speter log the numeric address as zero. This is a somewhat 778238032Speter bogus implementation in that it does an extra system 778338032Speter call, but it should be an inexpensive one. Fix from 778438032Speter Motonori Nakamura. 778538032Speter Tighten up handling of short syslog buffers even more -- there 778638032Speter were cases where the outgoing relay= name was too long 778738032Speter to share a line with delay= and mailer= logging. 778838032Speter Limit the overhead on split envelopes to one open file descriptor 778938032Speter per envelope -- previously the overhead was three 779038032Speter descriptors. This was in response to a problem reported 779138032Speter by P{r (Pell) Emanuelsson. 779238032Speter Fixes to better handle the case of unexpected connection closes; 779338032Speter this redirects the output to the transcript so the info 779438032Speter is not lost. From Eric Wassenaar. 779538032Speter Fix potential string overrun if you macro evaluate a string that 779638032Speter has a naked $ at the end. Problem noted by James Matheson 779738032Speter <jmrm@eng.cam.ac.uk>. 779838032Speter Make default error number on $#error messages 553 (``Requested 779938032Speter action not taken: mailbox name not allowed'') instead of 780038032Speter 501 (``Syntax error in parameters or arguments'') to 780138032Speter avoid bogus "protocol error" messages. 780238032Speter Strip off any existing trailing dot on names during $[ ... $] 780338032Speter lookup. This prevents it from ending up with two dots 780438032Speter on the end of dot terminated names. From Wesley Craig 780538032Speter of the University of Michigan and Bryan Costales of ICSI. 780638032Speter Clean up file class reading so that the debugging information is 780738032Speter more informative. It hadn't been using setclass, so you 780838032Speter didn't see the class items being added. 780938032Speter Avoid core dump if you are running a version of sendmail where 781038032Speter NIS is compiled in, and you specify an NIS map, but 781138032Speter NIS is not running. Fix from John Oleynick of 781238032Speter Rutgers. 781338032Speter Diagnose bizarre case where res_search returns a failure value, 781438032Speter but sets h_errno to a success value. 781538032Speter Make sure that "too many hops" messages are considered important 781638032Speter enough to send an error to the Postmaster (that is, the 781738032Speter address specified in the P option). This fix should 781838032Speter help problems that cause the df file to be left around 781938032Speter sometimes -- unfortunately, I can't seem to reproduce 782038032Speter the problem myself. 782138032Speter Avoid core dump (null pointer reference) on EXPN command; this 782238032Speter only occurred if your log level was set to 10 or higher 782338032Speter and the target account was an alias or had a .forward file. 782438032Speter Problem noted by Janne Himanka. 782538032Speter Avoid "denial of service" attacks by someone who is flooding your 782638032Speter SMTP port with bad commands by shutting the connection 782738032Speter after 25 bad commands are issued. From Kyle Jones of 782838032Speter UUNET. 782938032Speter Fix core dump on error messages with very long "to" buffers; 783038032Speter fmtmsg overflows the message buffer. Fixed by trimming 783138032Speter the to address to 203 characters. Problem reported by 783238032Speter John Oleynick. 783338032Speter Fix configuration for HASFLOCK -- there were some spots where 783438032Speter a #ifndef was incorrectly #ifdef. Pointed out by 783538032Speter George Baltz of the University of Maryland. 783638032Speter Fix a typo in savemail() that could cause the error message To: 783738032Speter lists to be incorrect in some places. From Motonori 783838032Speter Nakamura. 783938032Speter Fix a glitch that can cause duplicate error messages on split 784038032Speter envelopes where an address on one of the lists has a 784138032Speter name server failure. Fix from Voradesh Yenbut of the 784238032Speter University of Washington. 784338032Speter Fix possible bogus pointer reference on ESMTP parameters that 784438032Speter don't have an ``=value'' part. 784538032Speter CNAME loops caused an error message to be generated, but also 784638032Speter re-queued the message. Changed to just re-queue the 784738032Speter message (it's really hard to just bounce it because 784838032Speter of the weird way the name server works in the presence 784938032Speter of CNAME loops). Problem noted by James M.R.Matheson 785038032Speter of Cambridge University. 785138032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 785238032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 785338032Speter user name. Suggested by Andreas Stolcke of ICSI. 785438032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 785538032Speter override it easily in the Makefile -- that is, you can 785638032Speter turn it off using -DNAMED_BIND=0. 785738032Speter If a gethostbyname(...) of an address with a trailing dot fails, 785838032Speter try it without the trailing dot. This is because if 785938032Speter you have a version of gethostbyname() that falls back 786038032Speter to NIS or the /etc/hosts file it will fail to find 786138032Speter perfectly reasonable names that just don't happen to 786238032Speter be dot terminated in the hosts file. You don't want to 786338032Speter strip the dot first though because we're trying to ensure 786438032Speter that country names that match one of your subdomains get 786538032Speter a chance. 786638032Speter PRALIASES: fix bogus output on non-null-terminated strings. 786738032Speter From Bill Gianopoulos of Raytheon. 786838032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 786938032Speter This was in code intended to only catch the self-literal 787038032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 787138032Speter IP address), but the code was broken. However, it will 787238032Speter still do this if $M is defined; this is necessary to 787338032Speter get client configurations to work (sigh). Note that this 787438032Speter means that $M overrides :mailname entries in the user 787538032Speter database! Problem noted by Paul Southworth. 787638032Speter CONFIG: Fix definition of Solaris help file location. From 787738032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 787838032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 787938032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 788038032Speter and USENET_MAILER_MAX to tweak the maximum message 788138032Speter size for various mailers. 788238032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 788338032Speter instead of assuming that it is "inews" for consistency 788438032Speter with other mailers. From Michael Corrigan of UC San Diego. 788538032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 788638032Speter qualify the address in the SMTP envelope as user@{relay|hub} 788738032Speter instead of user@$j. From Bill Wisner of The Well. 788838032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 788938032Speter CONFIG: Don't turn off case mapping of user names in the local 789038032Speter mailer for IRIX. This was different than most every other 789138032Speter system. 789238032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 789338032Speter envelope. Noted by Thierry Besancon 789438032Speter <besancon@excalibur.ens.fr>. 789538032Speter CONFIG: Don't include -z by default on uux line -- most systems 789638032Speter don't want it set by default. Pointed out by Philippe 789738032Speter Michel of Thomson CSF. 789838032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 789938032Speter host name was foo.bar.ray.com and you matched against 790038032Speter ".ray.com", the old implementation bound %1 to "bar" 790138032Speter instead of "foo.bar". Also, allow "." in the mailertable 790238032Speter to match anything -- essentially, take over SMART_HOST. 790338032Speter This also moves matching of explicit local host names 790438032Speter before the mailertable so they don't have to be special 790538032Speter cased in the mailertable data. Reported by Bill 790638032Speter Gianopoulos of Raytheon; the fix for the %1 binding 790738032Speter problem was contributed by Nicholas Comanos of the 790838032Speter University of Sydney. 790938032Speter CONFIG: Don't include "root" in class $=L (users to deliver 791038032Speter locally, even if a hub or relay exists) by default. 791138032Speter This is because of the known bug where definition of 791238032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 791338032Speter both and deliver into the local mailbox. 791438032Speter CONFIG: Move up bitdomain and uudomain handling so that they 791538032Speter are done before .UUCP class matching; uudomain was 791638032Speter reported as ineffective before. This also frees up 791738032Speter diversion 8 for future use. Problem reported by Kimmo 791838032Speter Suominen. 791938032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 792038032Speter into host names. As pointed out by Jonathan Kamens, 792138032Speter these are often used because either the forward or reverse 792238032Speter mapping is broken; this translation makes it broken again. 792338032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 792438032Speter Suominen. 792538032Speter Portability fixes: 792638032Speter Unicos from David L. Kensiski of Sterling Software. 792738032Speter DomainOS from Don Lewis of Silicon Systems. 792838032Speter GNU m4 1.0.3 from Karst Koymans of Utrecht University. 792938032Speter Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. 793038032Speter NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. 793138032Speter BSD/386 from Tony Sanders of BSDI. 793238032Speter Apollo from Eric Wassenaar. 793338032Speter DGUX from Doug Anderson. 793438032Speter Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. 793538032Speter NEW FILES: 793638032Speter src/Makefile.DomainOS 793738032Speter src/Makefile.PTX 793838032Speter src/Makefile.SunOS.5.1 793938032Speter src/Makefile.SunOS.5.2 794038032Speter src/Makefile.SunOS.5.x 794138032Speter src/mailq.1 794238032Speter cf/ostype/domainos.m4 794338032Speter doc/op/Makefile 794438032Speter doc/intro/Makefile 794538032Speter doc/usenix/Makefile 794638032Speter 794764562Sgshapiro8.6.5/8.6.5 1994/01/13 794838032Speter Security fix: /.forward could be owned by anyone (the test 794938032Speter to allow root to own any file was backwards). From 795038032Speter Bob Campbell at U.C. Berkeley. 795138032Speter Security fix: group ids were not completely set when programs 795238032Speter were invoked. This caused programs to have group 795338032Speter permissions they should not have had (usually group 795438032Speter daemon instead of their own group). In particular, 795538032Speter Perl scripts would refuse to run. 795638032Speter Security: check to make sure files that are written are not 795738032Speter symbolic links (at least under some circumstances). 795838032Speter Although this does not respond to a specific known 795938032Speter attack, it's just a good idea. Suggested by 796038032Speter Christian Wettergren. 796138032Speter Security fix: if a user had an NFS mounted home directory on 796238032Speter a system with a restricted shell listed in their 796338032Speter /etc/passwd entry, they could still execute any 796438032Speter program by putting that in their .forward file. 796538032Speter This fix prevents that by insisting that their shell 796638032Speter appear in /etc/shells before allowing a .forward to 796738032Speter execute a program or write a file. You can disable 796838032Speter this by putting "*" in /etc/shells. It also won't 796938032Speter permit world-writable :include: files to reference 797038032Speter programs or files (there's no way to disable this). 797143730Speter These behaviors are only one level deep -- for 797238032Speter example, it is legal for a world-writable :include: 797338032Speter file to reference an alias that writes a file, on 797438032Speter the assumption that the alias file is well controlled. 797538032Speter Security fix: root was not treated suspiciously enough when 797638032Speter looking into subdirectories. This would potentially 797738032Speter allow a cracker to examine files that were publicly 797838032Speter readable but in a non-publicly searchable directory. 797938032Speter Fix a problem that causes an error on QUIT on a cached 798038032Speter connection to create problems on the current job. 798138032Speter These are typically unrelated, so errors occur in 798238032Speter the wrong place. 798338032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 798438032Speter runs more responsive to load average, and fixes a 798538032Speter problem that ignored the load average in locally 798638032Speter generated mail. From Eric Wassenaar. 798738032Speter Fix possible core dump on aliases with null LHS. From 798838032Speter John Orthoefer of BB&N. 798938032Speter Revert to using flock() whenever possible -- there are just 799038032Speter too many bugs in fcntl() locking, particularly over 799138032Speter NFS, that cause sendmail to fail in perverse ways. 799238032Speter Fix a bug that causes the connection cache to get confused 799338032Speter when sending error messages. This resulted in 799438032Speter "unexpected close" messages. It should fix itself 799538032Speter on the following queue run. Problem noted by 799638032Speter Liudvikas Bukys of the University of Rochester. 799738032Speter Include $k in $=k as documented in the Install & Op Guide. 799838032Speter This seems odd, but it was documented.... From 799938032Speter Michael Corrigan of UCSD. 800038032Speter Fix problem that caused :include:s from alias files to be 800138032Speter forced to be owned by root instead of daemon 800238032Speter (actually DefUid). From Tim Irvin. 800338032Speter Diagnose unrecognized I option values -- from Mortin Forssen 800438032Speter of the Chalmers University of Technology. 800538032Speter Make "error" mailer work consistently when there is no error 800638032Speter code associated with it -- previously it returned OK 800738032Speter even though there was a real problem. Now it assumes 800838032Speter EX_UNAVAILABLE. 800938032Speter Fix bug that caused the last header line of messages that had 801038032Speter no body and which were terminated with EOF instead of 801138032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 801238032Speter Fix core dump on SMTP mail to programs that failed -- it tried 801338032Speter to go to a "next MX host" when none existed, causing 801438032Speter a core dump. From der Mouse at McGill University. 801538032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 801638032Speter this makes it easier to turn it off (using 801738032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 801838032Speter Fix YP_MASTER_NAME store to use the unupdated result of 801938032Speter gethostname() (instead of myhostname(), which tries 802038032Speter to fully qualify the name) to be consistent with 802138032Speter SunOS. If your hostname is unqualified, this fixes 802238032Speter transfers to slave servers. Bug noted by Keith 802338032Speter McMillan of Ameritech Services, Inc. 802438032Speter Fix Ultrix problem: gethostbyname() can return a very large 802538032Speter (> 500) h_length field, which causes the sockaddr 802638032Speter to be trashed. Use the size of the sockaddr instead. 802738032Speter Fix from Bob Manson of Ohio State. 802838032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 802938032Speter defined -- this confuses gethostbyname on hosts 803038032Speter file lookups, which doesn't understand the trailing 803138032Speter dot convention. 803238032Speter Log SMTP server subprocesses that die with a signal instead 803338032Speter of from a clean exit. 803438032Speter If you don't have option "I" set, don't assume that a DNS 803538032Speter "host unknown" message is authoritative -- it 803638032Speter might still be found in /etc/hosts. 803738032Speter Fix a problem that would cause Deferred: messages to be sent 803838032Speter as the subject of an error message, even though the 803938032Speter actual cause of a message was more severe than that. 804038032Speter Problem noted by Chris Seabrook of OSSI. 804138032Speter Fix race condition in DBM alias file locking. From Kyle 804238032Speter Jones of UUNET. 804338032Speter Limit delivery syslog line length to avoid bugs in some 804438032Speter versions of syslog(3). This adds a new compile time 804538032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 804638032Speter University, which is in turn derived from IDA. 804738032Speter Fix quotes inside of comments in addresses -- previously 804838032Speter it insisted that they be balanced, but the 822 spec 804938032Speter says that they should be ignored. 805038032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 805138032Speter debugging). This also evaluates ruleset 89, if set 805238032Speter (with the null input), and logs the result. This 805338032Speter should be used sparingly, since the rewrite process 805438032Speter is not reentrant. 805538032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 805638032Speter documented in the Bat Book. 805738032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 805838032Speter return an error message and did not requeue the message. 805938032Speter Fix based on code from Roland Dirlewanger of 806038032Speter Reseau Regional Aquarel, Bordeaux, France. 806138032Speter Fix a problem that caused a seg fault if you got a 421 error 806238032Speter code during some parts of connection initialization. 806338032Speter I've only seen this when talking to buggy mailers on 806438032Speter the other end, but it shouldn't give a seg fault in 806538032Speter any case. From Amir Plivatsky. 806638032Speter Fix core dump caused by a ruleset call that returns null. 806738032Speter Fix from Bryan Costales of ICSI. 806838032Speter Full-Name: field was being ignored. Fix from Motonori Nakamura 806938032Speter of Kyoto University. 807038032Speter Fix a possible problem with very long input lines in setproctitle. 807138032Speter From P{r Emanuelsson. 807238032Speter Avoid putting "This is a warning message" out on return receipts. 807338032Speter Suggested by Douglas Anderson. 807438032Speter Detect loops caused by recursive ruleset calls. Suggested by 807538032Speter Bryan Costales. 807638032Speter Initialize non-alias maps during alias rebuilds -- they may be 807738032Speter needed for parsing. Problem noted by Douglas Anderson. 807838032Speter Log sender address even if no message was collected in SMTP 807938032Speter (e.g., if all RCPTs failed). Suggested by Motonori 808038032Speter Nakamura. 808138032Speter Don't reflect the owner-list contents into the envelope sender 808238032Speter address if the value contains ", :, /, or | (to avoid 808338032Speter illegal addresses appearing there). 808438032Speter Efficiency hack for toktype macro -- from Craig Partridge of 808538032Speter BB&N. 808638032Speter Clean up DNS error printing so that a host name is always 808738032Speter included. 808838032Speter Remember to set $i during queue runs. Reported by Stephen 808938032Speter Campbell of Dartmouth University. 809038032Speter If the environment variable HOSTALIASES is set, use it during 809138032Speter canonification as the name of a file with per-user host 809238032Speter translations so that headers are properly mapped. Reported 809338032Speter by Anne Bennett of Concordia University. 809438032Speter Avoid printing misleading error message if SMTP mailer (not 809538032Speter using [IPC]) should die on a core dump. 809638032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 809738032Speter by the other end closing the connection. From 809838032Speter Dave Morrison of Oracle. 809938032Speter Improve several of the error messages printed by "mailq" 810038032Speter to include a host name or other useful information. 810138032Speter Add NetInfo preliminary support for NeXT systems. From Vince 810238032Speter DeMarco. 810338032Speter Fix a glitch that sometimes caused :include:s that pointed to 810438032Speter NFS filesystems that were down to give an "aliasing/ 810538032Speter forwarding loop broken" message instead of queueing 810638032Speter the message for retry. Noted by William C Fenner of 810738032Speter the NRL Connection Machine Facility. 810838032Speter Fix a problem that could cause a core dump if the input sequence 810938032Speter had (or somehow acquired) a \231 character. 811038032Speter Make sure that route-addrs always have <angle brackets> around 811138032Speter them in non-SMTP envelopes (SMTP envelopes already do 811238032Speter this properly). 811338032Speter Avoid weird headers on unbalanced punctuation of the form: 811438032Speter ``Joe User <user)'' -- this caused reference to the 811538032Speter null macro. Fix from Rick McCarty of IO.COM. 811638032Speter Fix a problem that caused an alias "user: user@local.host" to 811738032Speter not have the QNOTREMOTE bit set; this caused configs 811838032Speter to act as if FEATURE(notsticky) was defined even when 811938032Speter it was not. The effect of the problem was to make it 812038032Speter very hard to to set up satellite sites that had a few 812138032Speter local accounts, with everything else forwarded to a 812238032Speter corporate hub. Reported by Detlef Drewanz of the 812338032Speter University of Rostock and Mark Frost of NCD. 812438032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 812538032Speter addresses. This is more efficient (fewer name server 812638032Speter calls) and fixes certain unusual configurations, such 812738032Speter as those that have ruleset 4 do something that is 812838032Speter non-idempotent unless a mailer-specific ruleset did 812938032Speter something else. Problem reported by Brian J. Coan 813038032Speter of the Institute for Global Communications. 813138032Speter Fix the "obsolete argument" routine in main to better understand 813238032Speter new arguments. For example, if you used ``sendmail 813338032Speter -C config -v -q'' it would choke on the -q because 813438032Speter the -C would stop looking for old-format arguments. 813538032Speter Fix the code that was intended to allow two users to forward their 813638032Speter mail to the same program and have them appear unique. 813738032Speter Portability fixes for: 813838032Speter SCO UNIX from Murray Kucherawy. 813938032Speter SCO Open Server 3.2v4 from Philippe Brand. 814038032Speter System V Release 4 from Rick Ellis and others. 814138032Speter OSF/1 from Steve Campbell. 814238032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 814338032Speter of Stoner Associates. 814438032Speter Motorola SysV88 from Kevin Johnson of Motorola. 814538032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 815938032Speter of the config file has moved to /usr/lib 816038032Speter to match the HP-UX version of sendmail. 816138032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 816238032Speter since this is intended only for internal use, the 816338032Speter usual RFC 821/822/1123 rules can be relaxed. The 816438032Speter main point of this is to avoid munging (ugh) UUCP 816538032Speter addresses when relaying internally. 816638032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 816738032Speter syntax addresses delivered via UUCP. Solution 816838032Speter provided by Peter Wemm. 816938032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 817038032Speter zero; it caused double @ signs in addresses. From 817138032Speter Irving Reid of the University of Toronto. 817238032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 817338032Speter from Markku Toijala of ICL Personal Systems Oy. 817438032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 817538032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 817638032Speter that made it hard to recognize your own pseudodomain 817738032Speter names. 817838032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 817938032Speter rather than letting them get "local configuration 818038032Speter error"s. Problem noted by John Gardiner Myers. 818138032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 818238032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 818338032Speter has uucp-dom semantics but old UUCP syntax. This 818438032Speter also permits "uucp-old" as an alias for "uucp" and 818538032Speter "uucp-new" as a synonym for "suucp" for consistency. 818638032Speter CONFIG: add POP mailer support (from Kimmo Suominen 818738032Speter <kim@grendel.lut.fi>). 818838032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 818938032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 819038032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 819138032Speter was set; it would get an additional @masquerade.host 819238032Speter added to the address. Problem noted by Peter Wan 819338032Speter of Georgia Tech. 819438032Speter CONFIG: make sure that the local UUCP name is in $=w. From 819538032Speter Jim Murray of Stratus. 819638032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 819738032Speter mailer flag. Briefly, if you are sending to host 819838032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 819938032Speter "foo!baz" remains "foo!baz", and anything else has 820038032Speter the local name prepended. 820138032Speter CONFIG: portability fixes for HP-UX. 820238032Speter DOC: several minor problems fixed in the Install & Op Guide. 820338032Speter MAKEMAP: fix core dump problem on lines that are too long or 820438032Speter which lack newline.

This 824038032Speter makes quite certain that crackers can't use this 824138032Speter class of attack. 824238032Speter Reliability Fix: check return value from fclose() and fsync() 824338032Speter in a few critical places. 824438032Speter Minor problem in initsys() that reversed a condition for 824538032Speter redirecting the output channel on queue runs. It's 824638032Speter not clear this code even does anything. From Eric 824738032Speter Wassenaar of the Dutch National Institute for Nuclear 824838032Speter and High-Energy Physics. 824938032Speter Fix some problems that caused queue runs to do "too much work", 825038032Speter such as double-reading the Errors-To: header. From 825138032Speter Eric Wassenaar. 825238032Speter Error messages on writing the temporary file (including the 825338032Speter data file) were getting suppressed in SMTP -- this 825438032Speter fix causes them to be properly reported. From Eric 825538032Speter Wassenaar. 825638032Speter Some changes to support AF_UNIX sockets -- this will only 825738032Speter really become relevant in the next release, but some 825838032Speter people need it for local patches. From Michael 825938032Speter Corrigan of UC San Diego. 826038032Speter Use dynamically allocated memory (instead of static buffers) 826138032Speter for macros defined in initsys() and settime(); since 826238032Speter these can have different values depending on which 826338032Speter envelope they are in. From Eric Wassenaar. 826438032Speter Improve logging to show ctladdr on to= logging; this tells you 826538032Speter what uid/gid processes ran as. 826638032Speter Fix a problem that caused error messages to be discarded if 826738032Speter the sender address was unparseable for some reason; 826838032Speter this was supposed to fall back to the "return to 826938032Speter postmaster" case. 827038032Speter Improve aliaswait backoff algorithm. 827138032Speter Portability patches for Linux (8.6.3 required another header 827238032Speter file) (from Karl London) and SCO UNIX. 827338032Speter CONFIG: patch prog mailer to not strip host name off of envelope 827438032Speter addresses (so that it matches local again). From 827538032Speter Christopher Davis. 827638032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 827738032Speter this prevents uux from seeing lines with null names like 827838032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 827938032Speter Nakamura of Kyoto University. 828038032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 828138032Speter it shouldn't fail miserably.

From Eric 830038032Speter Wassenaar. 830138032Speter Fix some server SMTP synchronization problems caused when 830238032Speter connections fail during message collection. From 830338032Speter Eric Wassenaar. 830438032Speter Fix a problem that can cause srvrsmtp to reject mail if the 830538032Speter name server is down -- it accepts the RCPT but rejects 830638032Speter the DATA command. Problem reported by Jim Murray of 830738032Speter Stratus. 830838032Speter Fix a problem that can cause core dumps if the config file 830938032Speter incorrectly resolves to a null hostname.

Fix 831538032Speter from Sven-Ove Westberg of the University of Lulea. 831638032Speter Under very odd circumstances, the alias file rebuild code 831738032Speter could get confused as to whether a database was 831838032Speter open or not. 831938032Speter Check "vendor code" on the end of V lines -- this is 832038032Speter intended to provide a hook for vendor-specific 832138032Speter configuration syntax. (This is a "new feature", 832238032Speter but I've made an exception to my rule in a belief 832338032Speter that this is a highly exceptional case.) 832438032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 832538032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 832638032Speter (from Jon Forrest of UC Berkeley) 832738032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 832838032Speter 832964562Sgshapiro8.6.1/8.6 1993/10/08 833038032Speter Portability fixes for A/UX and Encore UMAX V. 833138032Speter Fix error message handling -- if you had a name server down 833238032Speter causing an error during parsing, that message was never 833338032Speter propagated to the queue file. 833438032Speter 833564562Sgshapiro8.6/8.6 1993/10/05 833638032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 833738032Speter conf.h (other systems have the same bug). 833838032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 833938032Speter getdtablesize() instead of sysconf(); a disturbingly 834038032Speter large number of systems defined _SC_OPEN_MAX in the 834138032Speter header files but don't have the syscall. 834238032Speter Another patch to really truly ignore MX records in getcanonname 834338032Speter if trymx == FALSE. 834438032Speter Fix problem that caused the "250 IAA25499 Message accepted for 834538032Speter delivery" message to be omitted if there was an error 834638032Speter in the header of the message (e.g., a bad Errors-To: 834738032Speter line). Pointed out by Michael Corrigan of UCSD. 834838032Speter Announce name of host we are chatting when we get errors; this 834938032Speter is an IDA-ism suggested by Christophe Wolfhugel. 835038032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 835138032Speter Australian Artificial Intelligence Institute), SCO Unix 835238032Speter (from Murray Kucherawy of Hookup Communication Corp.), 835338032Speter NeXT (from Vince DeMarco and myself), Linux (from 835438032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 835538032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 835638032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 835738032Speter Some changes to get around gcc optimizer bugs. From Takahiro 835838032Speter Kanbe. 835938032Speter Fix error recovery in queueup if another tf file of the same 836038032Speter name already exists. Problem stumbled over by Bill 836138032Speter Wisner of The Well. 836238032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 836338032Speter Problem noted by Keith McMillan of Ameritech Services. 836438032Speter Deal with group permissions properly when opening .forward and 836538032Speter :include: files. This relaxes the 8.1C restrictions 836638032Speter slightly more. This includes proper setting of groups 836738032Speter when reading :include: files, allowing you to read some 836838032Speter files that you should be able to read but have previously 836938032Speter been denied unless you owned them or they had "other" 837038032Speter read permission. 837138032Speter Make certain that $j is in $=w (after the .cf is read) so that 837238032Speter if the user is forced to override some silly system, 837338032Speter MX suppression will still work. 837438032Speter Fix a couple of efficiency problems where newstr was double- 837538032Speter calling expensive routines. In at least one case, it 837638032Speter wasn't guaranteed that they would always return the 837738032Speter same result. Problem noted by Christophe Wolfhugel. 837838032Speter Fix null pointer dereference in putoutmsg -- only on an error 837938032Speter condition from a non-SMTP mailer. From Motonori 838038032Speter Nakamura. 838138032Speter Macro expand "C" line class definitions before scanning so that 838238032Speter "CX $Z" works. 838338032Speter Fix problem that caused error message to be sent while still 838438032Speter trying to send the original message if the connection 838538032Speter is closed during a DATA command after getting an error 838638032Speter on an RCPT command (pretty obscure). Problem reported 838738032Speter by John Myers of CMU. 838838032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 838938032Speter term bug. 839038032Speter Fix a nasty bug causing core dumps when returning the "warning: 839138032Speter cannot deliver for N hours -- will keep trying" message; 839243730Speter it only occurred if you had PostmasterCopy set and 839338032Speter only on some architectures. Although sendmail would 839438032Speter keep trying, it would send error messages on each 839538032Speter queue interval. This is an important fix. 839638032Speter Allow u and g options to take user and group names respectively. 839738032Speter Don't do a chdir into the queue directory in -bt mode to make 839838032Speter ruleset testing a bit easier. 839938032Speter Don't allow users to turn off logging (using -oL) on the command 840038032Speter line -- command line can only raise, not lower, logging 840138032Speter level. 840238032Speter Set $u to the original recipient on the SMTP transaction or on 840338032Speter the command line. This is only done if there is exactly 840438032Speter one recipient. Technically, this does not meet the 840538032Speter specs, because it does not guarantee a domain on the 840638032Speter address. 840738032Speter Fix a problem that dumped error messages on bad addresses if 840838032Speter you used the -t flag. Problem noted by Josh Smith of 840938032Speter Harvey Mudd College. 841038032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 841138032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 841238032Speter avoid the problem of people who use angle brackets in 841338032Speter their full name information. 841438032Speter Fix a null pointer dereference if you set option "l", have 841538032Speter an Errors-To: header in the message, and have Errors-To: 841638032Speter defined in the config file H lines. From J.R. Oldroyd. 841738032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 841838032Speter wrong when compiling. Suggested by Rick McCarty of TI. 841938032Speter Fix a problem that could pass negative SIZE parameter if the 842038032Speter df file got lost; this would cause servers to always 842138032Speter give a temporary failure, making the problem even worse. 842238032Speter Problem noted by Allan Johannesen of WPI. 842338032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 842438032Speter protocol timeouts (30s default). Requested by Murray 842538032Speter Kucherawy of HookUp Communication Corp. to handle bogus 842638032Speter PC TCP/IP implementations. 842738032Speter Change $w default definition to be just the first component of 842838032Speter the domain name on config level 5. The $j macro defaults 842938032Speter to the FQDN; $m remains as before. This lets well-behaved 843038032Speter config files use any of the short, long, or subdomain 843138032Speter names. 843238032Speter Add makesendmail script in src to try to automate multi-architecture 843338032Speter builds. I know, this is sub-optimal, but it is still 843438032Speter helpful. 843538032Speter Fix very obscure race condition that can cause a queue run to 843638032Speter get a queue file for an already completed job. This 843738032Speter problem has existed for years. Problem noted by the 843838032Speter long suffering Allan Johannesen of WPI. 843938032Speter Fix a problem that caused the raw sender name to be passed to 844038032Speter udbsender instead of the canonified name -- this caused 844138032Speter it to sometimes miss records that it should have found. 844238032Speter Relax check of name on HELO packet so that a program using -bs 844338032Speter that claims to be itself works properly. 844438032Speter Restore rewriting of $: part of address through 2, R, 4 in 844538032Speter buildaddr -- this requires passing a lot of flags to get 844638032Speter it right. Unlike old versions, this ONLY rewrites 844738032Speter recipient addresses, not sender addresses. 844838032Speter Fix a bug that caused core dumps in config files that cannot 844938032Speter resolve /file/name style addresses. Fix from Jonathan 845038032Speter Kamens of OpenVision Technologies. 845138032Speter Fix problem with fcntl locking that can cause error returns to 845238032Speter be lost if the lock is lost; this required fully 845338032Speter queueing everything, dropping the envelope (so errors 845438032Speter would get returned), and then re-reading the queue from 845538032Speter scratch. 845638032Speter Fix a problem that caused aliases that redefine an otherwise 845738032Speter true address to still send to the original address 845838032Speter if and only if the alias failed in certain bizarre 845938032Speter ways (e.g, if they pointed at a list:; syntax address). 846038032Speter Problem pointed out by Jonathan Kamens. 846138032Speter Remove support for frozen configuration files. They caused 846238032Speter more trouble than it was worth. 846338032Speter Fix problem that can cause error messages to get ignored when 846438032Speter using both -odb and -t flags. Problem noted by Rob 846538032Speter McNicholas at U.C. Berkeley. 846638032Speter Include all "normal" variations on hostname in $=w. For example, 846738032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 846838032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 846938032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 847038032Speter the queue. 847138032Speter Reset SmtpPhase global on initial connection creation so that 847238032Speter messages don't come out with stale information. 847338032Speter Pass an "ext" argument to lockfile so that error/log messages 847438032Speter will properly reflect the true filename being locked. 847538032Speter Put all [...] address forms into $=w -- this eliminates the need 847638032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 847738032Speter Myers of CMU. 847838032Speter Fix a bug that can cause qf files to be left around even after 847938032Speter an SMTP RSET command. Problem and fix from Michael 848038032Speter Corrigan. 848143730Speter Don't send a PostmasterCopy to errors when the Precedence: is 848238032Speter negative. Error reports still go to the envelope 848338032Speter sender address. 848438032Speter Add LA_SHORT for load averages. 848538032Speter Lock sendmail.st file when posting statistics. 848638032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 848738032Speter set the size of the TCP send and receive buffers; if you 848838032Speter run over a slow slip line you may need to set these down 848938032Speter (although it would be better to fix the SLIP implementation 849038032Speter so that it's not necessary to recompile every program 849138032Speter that does bulk data transfer). 849238032Speter Allow null defaults on $( ... $) lookups. Problem reported by 849338032Speter Amir Plivatsky. 849438032Speter Diagnose crufty S and V config lines. This resulted from an 849538032Speter observation that some people were using the SITE macro 849638032Speter without the SITECONFIG macro first, which was causing 849738032Speter bogus config files that were not caught. 849838032Speter Fix makemap -f flag to turn off case folding (it was turning it 849938032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 850038032Speter Fix a problem that caused multiple error messages to be sent if 850138032Speter you used "sendmail -t -oem -odb", your system uses fcntl 850238032Speter locking, and one of the recipient addresses is unknown. 850338032Speter Reset uid earlier in include() so that recursive .forwards or 850438032Speter :include:s don't use the wrong uid. 850538032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 850638032Speter called, the code to recover the descriptor was broken. 850738032Speter This sometimes (only sometimes) caused problems with the 850838032Speter alias file. Fix from Motonori Nakamura. 850938032Speter Fix a problem that caused aliaswait to go into infinite recursion 851038032Speter if the @:@ metasymbol wasn't found in the alias file. 851138032Speter Improve error message on newaliases if database files cannot be 851238032Speter opened or if running with no database format defined. 851338032Speter Do a better estimation of the size of error messages when NoReturn 851438032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 851538032Speter Fix a problem causing the "c" option (don't connect to expensive 851638032Speter mailers) to be ignored in SMTP. Problem noted and the 851738032Speter solution suggested by Robert Elz of The University of 851838032Speter Melbourne. 851938032Speter Improve connection caching algorithm by passing "[host]" to 852038032Speter hostsignature, which strips the square brackets and 852138032Speter returns the real name. This allows mailertable entries 852238032Speter to match regular entries. 852338032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 852438032Speter feature, even if it doesn't work right. 852538032Speter Catch and log attempts to try the "wiz" command in server SMTP. 852638032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 852738032Speter Be more generous at assigning $z to the home directory -- do this 852838032Speter for programs that are specified through a .forward file. 852938032Speter Fix from Andrew Chang of Sun Microsystems. 853038032Speter Always save a fatal error message in preference to a non-fatal 853138032Speter error message so that the "subject" line of return 853238032Speter messages is the best possible. 853338032Speter CONFIG: reduce the number of quotes needed to quote configuration 853438032Speter parameters with commas: two quotes should work now, e.g., 853538032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 853638032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 853738032Speter connections (domain-ized UUCP). 853838032Speter CONFIG: fix bug in default maps (-o must be before database file 853964562Sgshapiro name). Pointed out by Christophe Wolfhugel. 854038032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 854138032Speter DNS. This would presumably be used in UUCP islands. 854238032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 854338032Speter CONFIG: log $u in Received: line. This is in technical violation 854438032Speter of the standards, since it doesn't guarantee a domain 854538032Speter on the address. 854638032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 854738032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 854838032Speter the "m" flag should you want it. Apparently some Solaris 2.2 854938032Speter installations can't handle multiple local recipients. 855038032Speter Problem noted by Josh Smith. 855138032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 855238032Speter CONFIG: change default version level from 4 to 5. 855338032Speter CONFIG: add FEATURE(nullclient) to create a config file that 855438032Speter forwards all mail to a hub without ever looking at the 855538032Speter addresses in any detail. 855638032Speter CONFIG: properly strip mailer: information off of relays when 855738032Speter used to change .BITNET form into %-hack form. 855838032Speter CONFIG: fix a problem that caused infinite loops if presented 855938032Speter with an address such as "!foo". 856038032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 856138032Speter the reverse "PTR" mapping is broken. There's a better 856238032Speter way to do this, but the change is fairly major and I 856338032Speter want to hold it for another release. Problem noted by 856438032Speter Bret Marquis. 856538032Speter 856664562Sgshapiro8.5/8.5 1993/07/23 856738032Speter Serious bug: if you used a command line recipient that was unknown 856838032Speter sendmail would not send a return message (it was treating 856938032Speter everything as though it had an SMTP-style client that 857038032Speter would do the return itself). Problem noted by Josh Smith. 857138032Speter Change "trymx" option in getcanonname() to ignore all MX data, 857238032Speter even during a T_ANY query. This actually didn't break 857338032Speter anything, because the only time you called getcanonname 857438032Speter with !trymx was if you already knew there were no MX 857538032Speter records, but it is somewhat cleaner. From Motonori 857638032Speter Nakamura. 857738032Speter Don't call getcanonname from getmxrr if you already know there 857838032Speter are no DNS records matching the name. 857938032Speter Fix a problem causing error messages to always include "The 858038032Speter original message was received ... from localhost". 858138032Speter The correct original host information is now included. 858238032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 858338032Speter version of "test" doesn't have the -x flag). Change it 858438032Speter to use -f instead. From John Myers. 858538032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 858638032Speter esmtp -- it should be smtp. 858738032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 858838032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 858938032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 859038032Speter this cleans up the configs somewhat. This fixes a serious 859138032Speter problem that caused route-addrs to get mistaken as relays, 859238032Speter pointed out by John Myers. WARNING: this also causes 859338032Speter the default on SMART_HOST to change from "suucp" to 859438032Speter "relay" if you have MAILER(smtp) specified. 859538032Speter 859664562Sgshapiro8.4/8.4 1993/07/22 859738032Speter Add option `w'. If you receive a message that comes to you because 859838032Speter you are the best (lowest preference) target of an MX, and 859938032Speter you haven't explicitly recognized the source MX host in 860038032Speter your .cf file, this option will cause you to try the target 860138032Speter host directly (as if there were no MX for it at all). If 860238032Speter `w' is not set, this case is a configuration error. 860338032Speter Beware: if `w' is set, senders may get bogus errors like 860438032Speter "message timed out" or "host unknown" for problems that 860538032Speter are really configuration errors. This option is 860638032Speter disrecommended, provided only for compatibility with 860738032Speter UIUC sendmail. 860838032Speter Fix a problem that caused the incoming socket to be left open 860938032Speter when sendmail forks after the DATA command. This caused 861038032Speter calling systems to wait in FIN_WAIT_2 state until the 861138032Speter entire list was processed and the child closed -- a 861238032Speter potentially prodigious amount of time. Problem noted 861338032Speter by Neil Rickert. 861438032Speter Fix problem (created in 6.64) that caused mail sent to multiple 861538032Speter addresses, one of which was a bad address, to completely 861638032Speter suppress the sending of the message. This changes 861738032Speter handling of EF_FATALERRS somewhat, and adds an 861838032Speter EF_GLOBALERRS flag. This also fixes a potential problem 861938032Speter with duplicate error messages if there is a syntax error 862038032Speter in the header of a message that isn't noticed until late 862138032Speter in processing. Original problem pointed out by Josh Smith 862238032Speter of Harvey Mudd College. This release includes quite a bit 862338032Speter of dickering with error handling (see below). 862438032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 862538032Speter will only hurt already-broken software and should help 862638032Speter humans. 862738032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 862838032Speter compiled in. It would never read the alias file. 862938032Speter Repair unbalanced `)' and `>' (the "open" versions are already 863038032Speter repaired). 863138032Speter Logging of "done" in dropenvelope() was incorrect: it would 863238032Speter log this even when the queue file still existed. Change 863338032Speter this to only log "done" (at log level 11) when the 863438032Speter queue file is actually removed. From John Myers. 863538032Speter Log "lost connection" in server SMTP at log level 20 if there 863638032Speter is no pending transaction. Some senders just close the 863738032Speter connection rather than sending QUIT. 863838032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 863938032Speter domains that do not have MX records -- this would cause 864038032Speter the subsequent host name lookup to fail. The problem 864138032Speter only occurred if you had FEATURE(nocanonify) set. 864238032Speter Problem noted by Rick McCarty of Texas Instruments. 864338032Speter Fix invocation of setvbuf when passed a -X flag -- I had 864438032Speter unwittingly used an ANSI C extension, and this caused 864538032Speter core dumps on some machines. 864638032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 864738032Speter Previously it just gave an empty send queue, which 864838032Speter then gave either "Need RCPT (recipient)" at the DATA 864938032Speter (confusing, since you had given an RCPT command which 865038032Speter returned 250) or just dropped the email, depending on 865138032Speter whether you were running VERBose mode. Now it usually 865238032Speter diagnoses this case as "aliasing/forwarding loop broken". 865338032Speter Unfortunately, it still doesn't adequately diagnose 865438032Speter some true error conditions. 865538032Speter Add internal concept of "warning messages" using 6xx codes. 865638032Speter These are not reported only to Postmaster. Unbalanced 865738032Speter parens, brackets, and quotes are printed as 653 codes. 865838032Speter They are always mapped to 5xx codes before use in SMTP. 865938032Speter Clean up error messages to tell both the actual address that 866038032Speter failed and the alias they arose from. This makes it 866138032Speter somewhat easier to diagnose problems. Difficulty noted 866238032Speter by Motonori Nakamura. 866338032Speter Fix a problem that inappropriately added a ctladdr to addresses 866438032Speter that shouldn't have had one during a queue run. This 866538032Speter caused error messages to be handled differently during 866638032Speter a queue run than a direct run. 866738032Speter Don't print the qf name and line number if you get errors during 866838032Speter the direct run of the queue from srvrsmtp -- this was 866938032Speter just extra stuff for users to crawl through. 867038032Speter Put command line flags on second line of pid file so you can 867138032Speter auto-restart the daemon with all appropriate arguments. 867238032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 867338032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 867438032Speter restart it. 867538032Speter Remove the ``setuid(getuid())'' in main -- this caused the 867638032Speter IDENT daemon to screw up. This required that I change 867738032Speter HASSETEUID to HASSETREUID and complicate the mode 867838032Speter changing somewhat because both Ultrix and SunOS seem 867938032Speter to have a bug causing seteuid() to set the saved uid 868038032Speter as well as the effective. The program test/t_setreuid.c 868138032Speter will test to see if your implementation of setreuid(2) 868238032Speter is appropriately functional. 868338032Speter The FallBackMX (option V) handling failed to properly identify 868438032Speter fallback to yourself -- most of the code was there, 868538032Speter but it wasn't being enabled. Problem noted by Murray 868638032Speter Kucherawy of the University of Waterloo. 868738032Speter Change :include: open timeout from ETIMEDOUT to an internal 868838032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 868938032Speter with CurHostName" in error messages, which can be 869038032Speter confusing. Reported by Jonathan Kamens of OpenVision 869138032Speter Technologies. 869238032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 869338032Speter process group id. The original fix was to get around 869438032Speter some problems with recalcitrant MUAs, but it breaks 869538032Speter any call from a shell that creates a process group id 869638032Speter different from the process id. I could try to fix 869738032Speter this by diddling the tty owner (using tcsetpgrp or 869838032Speter equivalent) but this is too likely to break other 869938032Speter things. 870038032Speter Portability changes: 870138032Speter Support -M as equivalent to -oM on Ultrix -- apparently 870238032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 870338032Speter instead of using standard flags. Oh joy. This 870443730Speter behavior reported by Jon Giltner of University 870538032Speter of Colorado. 870638032Speter SGI IRIX -- this includes several changes that should 870738032Speter help other strict ANSI compilers. 870838032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 870938032Speter Corporation. 871038032Speter Solaris running the Sun C compiler (which despite the 871138032Speter documentation apparently doesn't define 871238032Speter __STDC__ by default). 871338032Speter ConvexOS from Eric Schnoebelen of Convex. 871438032Speter Sony NEWS workstations and Omron LUNA workstations from 871538032Speter Motonori Nakamura. 871638032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 871738032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 871838032Speter several people have made a good argument that this 871938032Speter creates more problems than it solves (although this 872038032Speter may prove painful in the short run). 872138032Speter CONFIG: generalize all the relays to accept a "mailer:host" 872238032Speter format. 872338032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 872438032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 872538032Speter addresses are also passed through this ruleset. 872638032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 872738032Speter internet-style addresses would "fall off the end" of 872838032Speter ruleset zero and be interpreted as local -- however, 872938032Speter the angle brackets confused the recursive call. 873038032Speter These are now diagnosed as "Unrecognized host name". 873138032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 873238032Speter ifdef(`_MAILER_USENET_') instead of 873338032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 873438032Speter of SINTEF RUNIT, Oslo. 873538032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 873638032Speter early in ruleset 0; this allows .mc authors to bypass 873738032Speter things like the "short circuit" code for local addresses. 873838032Speter Prompted by a comment by Bill Wisner of The Well. 873938032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 874038032Speter esmtp) to send SMTP mail. This allows you to default 874138032Speter to esmtp but use a mailertable or other override to 874238032Speter deal with broken servers. This logic was pointed out 874338032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 874438032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 874538032Speter environments. Ugly as sin. 874638032Speter 874764562Sgshapiro8.3/8.3 1993/07/13 874838032Speter Fix setuid problems introduced in 8.2 that caused messages 874938032Speter like "Cannot create qfXXXXXX: Invalid argument" 875038032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 875138032Speter involved a new compile flag "HASSETEUID" that takes 875238032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 875338032Speter that the POSIX interface is broken enough to break 875438032Speter some systems badly. This includes some fixes for 875538032Speter HP-UX. Also fixes problems where the real uid is 875638032Speter not reset properly on startup (from Neil Rickert). 875738032Speter Fix a problem that caused timed out messages to not report the 875838032Speter addresses that timed out. Error messages are also more 875938032Speter "user friendly". 876038032Speter Drop required bandwidth on connections from 64 bytes/sec to 876138032Speter 16 bytes/sec. 876238032Speter Further Solaris portability changes -- doesn't require the BSD 876338032Speter compatibility library. This also adds a new 876438032Speter "HASGETDTABLESIZE" compile flag which can be used if 876538032Speter you want to use getdtablesize(2) instead of sysconf(2). 876638032Speter These are loosely based on changes from David Meyer at 876738032Speter University of Oregon. This now seems to work, at least 876838032Speter for quick test cases. 876938032Speter Fix a problem that can cause duplicate error messages to be 877038032Speter sent if you are in SMTP, you send to multiple addresses, 877138032Speter and at least one of those addresses is good and points 877238032Speter to an account that has a .forward file (whew!). 877338032Speter Fix a problem causing messages to be discarded if checkcompat() 877438032Speter returned EX_TEMPFAIL (because it didn't properly mark 877538032Speter the "to" address). Problem noted by John Myers. 877638032Speter Fix dfopen to return NULL if the open failed; I was depending 877738032Speter on fdopen(-1) returning NULL, which isn't the case. This 877838032Speter isn't serious, but does result in weird error diagnoses. 877938032Speter From Michael Corrigan. 878038032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 878138032Speter messages sent through UUCP-family mailers. Suggested 878238032Speter by Bill Wisner of The Well. 878338032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 878438032Speter include a "uucp-dom" mailer that uses domain-style 878538032Speter addressing. Suggested by Bill Wisner. 878638032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 878738032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 878838032Speter Christophe Wolfhugel. 878938032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 879038032Speter 879164562Sgshapiro8.2/8.2 1993/07/11 879238032Speter Don't drop out on config file parse errors in -bt mode. 879338032Speter On older configuration files, assume option "l" (use Errors-To 879438032Speter header) for back compatibility. NOTE: this DOES NOT 879538032Speter imply an endorsement of the Errors-To: header in any way. 879638032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 879738032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 879838032Speter SMTP server to give an error on this command, and 879938032Speter logging it in the transcript can be confusing. Fix 880038032Speter from Bill Wisner. 880138032Speter IRIX compatibility changes provided by Dan Rich 880238032Speter <drich@sandman.lerc.nasa.gov>. 880338032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 880438032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 880538032Speter <juo@klinzhai.rutgers.edu> 880638032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 880738032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 880838032Speter match the other flags in that file. 880938032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 881038032Speter Save h_errno in mci struct and improve error message display. 881138032Speter Changes from Eric Wassenaar. 881238032Speter Open /dev/null for the transcript if the create of the xf file 881338032Speter failed; this avoids at least one possible null pointer 881438032Speter reference in very weird cases. From Eric Wassenaar. 881538032Speter Clean up statistics gathering; it was over-reporting because of 881638032Speter forks. From Eric Wassenaar. 881738032Speter Fix problem that causes old Return-Path: line to override new 881838032Speter Return-Path: line (conf.c needs H_FORCE to avoid 881938032Speter re-using old value). From Motonori Nakamura. 882038032Speter Fix broken -m flag in K definition -- even if -m (match only) 882138032Speter was specified, it would still replace the key with the 882238032Speter value. Noted by Rick McCarty of Texas Instruments. 882338032Speter If the name server timed out over several days, no "timed out" 882438032Speter message would ever be sent back. The timeout code 882538032Speter has been moved from markfailure() to dropenvelope() 882638032Speter so that all such failures should be diagnosed. Pointed 882738032Speter out by Christophe Wolfhugel and others. 882838032Speter Relax safefile() constraints: directories in an include or 882938032Speter forward path must be readable by self if the controlling 883038032Speter user owns the entry, readable by all otherwise (e.g., 883138032Speter when reading your .forward file, you have to own and 883238032Speter have X permission in it; everyone needs X permission in 883338032Speter the root and directories leading up to your home); 883438032Speter include files must be readable by anyone, but need not 883538032Speter be owned by you. 883638032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 883738032Speter reading a .forward file; this gets around some problems 883838032Speter on NFS mounts if root permission is not exported and 883938032Speter the user's home directory isn't x'able. 884038032Speter Additional NeXT portability enhancements from Axel Zinser. 884138032Speter Additional HP-UX portability enhancements from Brian Bullen. 884238032Speter Add a timeout around SMTP message writes; this assumes you can 884338032Speter get throughput of at least 64 bytes/second. Note that 884438032Speter this does not impact the "datafinal" default, which 884538032Speter is separate; this is just intended to work around 884638032Speter network clogs that will occur before the final dot 884738032Speter is sent. From Eric Wassenaar. 884838032Speter Change map code to set the "include null" flag adaptively -- 884938032Speter it initially tries both, but if it finds anything 885038032Speter matching without a null it never tries again with a 885138032Speter null and vice versa. If -N is specified, it never 885238032Speter tries without the null and creates new maps with a 885338032Speter null byte. If -O is specified, it never tries with 885438032Speter the null (for efficiency). If -N and -O are specified, 885538032Speter you get -NO (get it?) lookup at all, so this would 885638032Speter be a bad idea. If you don't specify either -N or -O, 885738032Speter it adapts. 885838032Speter Fix recognition of "same from address" so that MH submissions 885938032Speter will insert the appropriate full name information; 886038032Speter this used to work and got broken somewhere along the 886138032Speter way. 886238032Speter Some changes to eliminate some unnecessary SYSERRs in the 886338032Speter log. For example, if you lost a connection, don't 886438032Speter bother reporting that fact on the connection you lost. 886538032Speter Add some "extended debugging" flags to try to track down 886638032Speter why we get occasional problems with file descriptor 886738032Speter one being closed when execing a mailer; it seems to 886838032Speter only happen when there has been another error in the 886938032Speter same transaction. This requires XDEBUG, defined 887038032Speter by default in conf.h. 887138032Speter Add "-X filename" command line flag, which logs both sides of 887238032Speter all SMTP transactions. This is intended ONLY for 887338032Speter debugging bad implementations of other mailers; start 887438032Speter it up, send a message from a mailer that is failing, 887538032Speter and then kill it off and examine the indicated log. 887638032Speter This output is not intended to be particularly human 887738032Speter readable. This also adds the HASSETVBUF compile 887838032Speter flag, defaulted on if your compiler defines __STDC__. 887938032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 888038032Speter have a local net that should get direct connects, you 888138032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 888238032Speter See cf/README for an example. 888338032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 888438032Speter sites that don't use the -d flag. 888538032Speter CONFIG: hide recipient addresses as well as sender addresses 888638032Speter behind $M if FEATURE(allmasquerade) is specified; this 888738032Speter has been requested by several people, but can break 888838032Speter local aliases. For example, if you mail to "localalias" 888938032Speter this will be rewritten as "localalias@masqueradehost"; 889038032Speter although initial delivery will work, replies will be 889138032Speter broken. Use it sparingly. 889238032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 889338032Speter to qualified domains in headers. I believe this is 889438032Speter largely equivalent to the IDA feature of the same name. 889538032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 889638032Speter to override the "system name" as your UUCP name -- 889738032Speter in particular, to use domain-ized UUCP names. From 889838032Speter Bill Wisner of The Well. 889938032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 890038032Speter first. This is currently unused in the config files, 890138032Speter but could be used in a mailertable entry. 890238032Speter 890364562Sgshapiro8.1C/8.1B 1993/06/27 890438032Speter Serious security bug fix: it was possible to read any file on 890538032Speter the system, regardless of ownership and permissions. 890638032Speter If a subroutine returns a fully qualified address, return it 890738032Speter immediately instead of feeding it back into rewriting. 890838032Speter This fixes a problem with mailertable lookups. 890938032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 891038032Speter 891164562Sgshapiro8.1B/8.1A 1993/06/12 891238032Speter Serious bug fix: pattern matching backup algorithm stepped by 891338032Speter two tokens in classes instead of one. Found by Claus 891438032Speter Assmann at University of Kiel, Germany. 891538032Speter 891664562Sgshapiro8.1A/8.1A 1993/06/08 891738032Speter Another mailertable fix.... 891838032Speter 891964562Sgshapiro8.1/8.1 1993/06/07 892038032Speter 4.4BSD freeze.
