Problem found by Michal Zalewski. 13112810Sgshapiro Note: an MTA that is not patched might be vulnerable to 14112810Sgshapiro data that it receives from untrusted sources, which 15112810Sgshapiro includes DNS. 16112810Sgshapiro To provide partial protection to internal, unpatched sendmail MTAs, 17112810Sgshapiro 8.12.9 changes by default (char)0xff to (char)0x7f in 18112810Sgshapiro headers etc. To turn off this conversion compile with 19112810Sgshapiro -DALLOW_255 or use the command line option -d82.101. 20112810Sgshapiro To provide partial protection for internal, unpatched MTAs that may be 21112810Sgshapiro performing 7->8 or 8->7 bit MIME conversions, the default 22112810Sgshapiro for MaxMimeHeaderLength has been changed to 2048/1024. 23112810Sgshapiro Note: this does have a performance impact, and it only 24112810Sgshapiro protects against frontal attacks from the outside. 25112810Sgshapiro To disable the checks and return to pre-8.12.9 defaults, 26112810Sgshapiro set MaxMimeHeaderLength to 0/0. 27112810Sgshapiro Do not complain about -ba when submitting mail. Problem noted 28112810Sgshapiro by Derek Wueppelmann. 29112810Sgshapiro Fix compilation with Berkeley DB 1.85 on systems that do not 30112810Sgshapiro have flock(2). Problem noted by Andy Harper of Kings 31112810Sgshapiro College London. 32112810Sgshapiro Properly initialize data structure for dns maps to avoid various 33112810Sgshapiro errors, e.g., looping processes. Problem noted by 34112810Sgshapiro Maurice Makaay. 35112810Sgshapiro CONFIG: Prevent multiple application of rule to add smart host. 36112810Sgshapiro Patch from Andrzej Filip. 37112810Sgshapiro CONFIG: Fix queue group declaration in MAILER(`usenet'). 38112810Sgshapiro CONTRIB: buildvirtuser: New option -t builds the virtusertable 39112810Sgshapiro text file instead of the database map. 40112810Sgshapiro Portability: 41112810Sgshapiro Revert wrong change made in 8.12.7 and actually use the 42112810Sgshapiro builtin getopt() version in sendmail on Linux. 43112810Sgshapiro This can be overridden by using -DSM_CONF_GETOPT=0 44112810Sgshapiro in which case the OS supplied version will be used. 45112810Sgshapiro 46111823Sgshapiro8.12.8/8.12.8 2003/02/11 47111823Sgshapiro SECURITY: Fix a remote buffer overflow in header parsing by 48111823Sgshapiro dropping sender and recipient header comments if the 49111823Sgshapiro comments are too long. Problem noted by Mark Dowd 50111823Sgshapiro of ISS X-Force. 51111823Sgshapiro Fix a potential non-exploitable buffer overflow in parsing the 52111823Sgshapiro .cf queue settings and potential buffer underflow in 53111823Sgshapiro parsing ident responses. Problem noted by Yichen Xie of 54111823Sgshapiro Stanford University Compilation Group. 55111823Sgshapiro Fix ETRN #queuegroup command: actually start a queue run for 56111823Sgshapiro the selected queue group. Problem noted by Jos Vos. 57111823Sgshapiro If MaxMimeHeaderLength is set and a malformed MIME header is fixed, 58111823Sgshapiro log the fixup as "Fixed MIME header" instead of "Truncated 59111823Sgshapiro MIME header". Problem noted by Ian J Hart. 60111823Sgshapiro CONFIG: Fix regression bug in proto.m4 that caused a bogus 61111823Sgshapiro error message: "FEATURE() should be before MAILER()". 62111823Sgshapiro MAIL.LOCAL: Be more explicit in some error cases, i.e., whether 63111823Sgshapiro a mailbox has more than one link or whether it is not 64111823Sgshapiro a regular file. Patch from John Beck of Sun Microsystems. 65111823Sgshapiro 66110560Sgshapiro8.12.7/8.12.7 2002/12/29 67110560Sgshapiro Properly clean up macros to avoid persistence of session data 68110560Sgshapiro across various connections. This could cause session 69110560Sgshapiro oriented restrictions, e.g., STARTTLS requirements, 70110560Sgshapiro to erroneously allow a connection. Problem noted 71110560Sgshapiro by Tim Maletic of Priority Health. 72110560Sgshapiro Do not lookup MX records when sorting the MSP queue. The MSP 73110560Sgshapiro only needs to relay all mail to the MTA. Problem found 74110560Sgshapiro by Gary Mills of the University of Manitoba. 75110560Sgshapiro Do not restrict the length of connection information to 100 76110560Sgshapiro characters in some logging statements. Problem noted by 77110560Sgshapiro Erik Parker. 78110560Sgshapiro When converting an enhanced status code to an exit status, use 79110560Sgshapiro EX_CONFIG if the first digit is not 2, 4, or 5 or if *.1.5 80110560Sgshapiro is used. 81110560Sgshapiro Reset macro $x when receiving another MAIL command. Problem 82110560Sgshapiro noted by Vlado Potisk of Wigro s.r.o. 83110560Sgshapiro Don't bother setting the permissions on the build area statistics 84110560Sgshapiro file, the proper permissions will be put on the file at 85110560Sgshapiro install time. This fixes installation over NFS for some 86110560Sgshapiro users. Problem noted by Martin J. Dellwo of 3-Dimensional 87110560Sgshapiro Pharmaceuticals, Inc. 88110560Sgshapiro Fix problem of decoding SASLv2 encrypted data. Problem noted by 89110560Sgshapiro Alex Deiter of Mobile TeleSystems, Komi Republic. 90110560Sgshapiro Log milter socket open errors at MilterLogLevel 1 or higher instead 91110560Sgshapiro of 11 or higher. 92110560Sgshapiro Print early system errors to the console instead of silently 93110560Sgshapiro exiting. Problem noted by James Jong of IBM. 94110560Sgshapiro Do not process a queue group if Runners is set to 0, regardless 95110560Sgshapiro of whether F=f or sendmail is run in verbose mode (-v). 96110560Sgshapiro The use of -qGname will still force queue group "name" 97110560Sgshapiro to be run even if Runners=0. 98110560Sgshapiro Change the level for logging the fact that a daemon is refusing 99110560Sgshapiro connections due to high load from LOG_INFO to LOG_NOTICE. 100110560Sgshapiro Patch from John Beck of Sun Microsystems. 101110560Sgshapiro Use location information for submit.cf from NetInfo 102110560Sgshapiro (/locations/sendmail/submit.cf) if available. 103110560Sgshapiro Re-enable ForkEachJob which was lost in 8.12.0. Problem noted by 104110560Sgshapiro Neil Rickert of Northern Illinois University. 105110560Sgshapiro Make behavior of /canon in debug mode consistent with usage in 106110560Sgshapiro rulesets. Patch from Shigeno Kazutaka of IIJ. 107110560Sgshapiro Fix a potential memory leak in envelope splitting. Problem noted 108110560Sgshapiro by John Majikes of IBM. 109110560Sgshapiro Do not try to share an mailbox database LDAP connection across 110110560Sgshapiro different processes. Problem noted by Randy Kunkee. 111110560Sgshapiro Fix logging for undelivered recipients when the SMTP connection 112110560Sgshapiro times out during message collection. Problem noted by Neil 113110560Sgshapiro Rickert of Northern Illinois University. 114110560Sgshapiro Avoid problems with QueueSortOrder=random due to problems with 115110560Sgshapiro qsort() on Solaris (and maybe some other operating systems). 116110560Sgshapiro Problem noted by Stephan Schulz of Gruner+Jahr.. 117110560Sgshapiro If -f "" is specified, set the sender address to "<>". Problem 118110560Sgshapiro noted by Matthias Andree. 119110560Sgshapiro Fix formatting problem of footnotes for plain text output on some 120111823Sgshapiro versions of tmac. Patch from Per Hedeland. 121110560Sgshapiro Portability: 122110560Sgshapiro Berkeley DB 4.1 support (requires at least 4.1.25). 123110560Sgshapiro Some getopt(3) implementations in GNU/Linux are broken 124110560Sgshapiro and pass a NULL pointer to an option which requires 125110560Sgshapiro an argument, hence the builtin version of 126110560Sgshapiro sendmail is used instead. This can be overridden 127110560Sgshapiro by using -DSM_CONF_GETOPT=0. Problem noted by 128110560Sgshapiro Vlado Potisk of Wigro s.r.o. 129110560Sgshapiro Support for nph-1.2.0 from Mark D. Roth of the University 130110560Sgshapiro of Illinois at Urbana-Champaign. 131110560Sgshapiro Support for FreeBSD 5.0's MAC labeling from Robert Watson 132110560Sgshapiro of the TrustedBSD Project. 133110560Sgshapiro Support for reading the number of processors on an IRIX 134110560Sgshapiro system from Michel Bourget of SGI. 135110560Sgshapiro Support for UnixWare 7.1 based on input from Larry Rosenman. 136110560Sgshapiro Interix support from Nedelcho Stanev of Atlantic Sky 137110560Sgshapiro Corporation. 138110560Sgshapiro Update Mac OS X/Darwin portability from Wilfredo Sanchez. 139110560Sgshapiro CONFIG: Enforce tls_client restrictions even if delay_checks 140110560Sgshapiro is used. Problem noted by Malte Starostik. 141110560Sgshapiro CONFIG: Deal with an empty hostname created via bogus 142110560Sgshapiro DNS entries to get around access restrictions. 143110560Sgshapiro Problem noted by Kai Schlichting. 144110560Sgshapiro CONFIG: Use FEATURE(`msp', `[127.0.0.1]') in submit.mc by default 145110560Sgshapiro to avoid problems with hostname resolution for localhost 146110560Sgshapiro which on many systems does not resolve to 127.0.0.1 (or 147110560Sgshapiro ::1 for IPv6). If you do not use IPv4 but only IPv6 then 148110560Sgshapiro you need to change submit.mc accordingly, see the comment 149110560Sgshapiro in the file itself. 150110560Sgshapiro CONFIG: Set confDONT_INIT_GROUPS to True in submit.mc to avoid 151110560Sgshapiro error messages from initgroups(3) on AIX 4.3 when sending 152110560Sgshapiro mail to non-existing users. Problem noted by Mark Roth of 153110560Sgshapiro the University of Illinois at Urbana-Champaign. 154110560Sgshapiro CONFIG: Allow local_procmail to override local_lmtp settings. 155110560Sgshapiro CONFIG: Always allow connections from 127.0.0.1 or IPv6:::1 to 156110560Sgshapiro relay. 157110560Sgshapiro CONTRIB: cidrexpand: Deal with the prefix tags that may be included 158110560Sgshapiro in access_db. 159110560Sgshapiro CONTRIB: New version of doublebounce.pl contributed by Leo Bicknell. 160110560Sgshapiro LIBMILTER: On Solaris libmilter may get into an endless loop if 161110560Sgshapiro an error in the communication from/to the MTA occurs. 162110560Sgshapiro Patch from Gurusamy Sarathy of Active State. 163110560Sgshapiro LIBMILTER: Ignore EINTR from sigwait(3) which may happen on Tru64. 164110560Sgshapiro Patch from from Jose Marcio Martins da Cruz of Ecole 165110560Sgshapiro Nationale Superieure des Mines de Paris. 166110560Sgshapiro MAIL.LOCAL: Fix a truncation race condition if the close() on 167110560Sgshapiro the mailbox fails. Problem noted by Tomoko Fukuzawa of 168110560Sgshapiro Sun Microsystems. 169110560Sgshapiro MAIL.LOCAL: Fix a potential file descriptor leak if mkstemp(3) 170110560Sgshapiro fails. Patch from John Beck of Sun Microsystems. 171110560Sgshapiro SMRSH: SECURITY: Only allow regular files or symbolic links to be 172110560Sgshapiro used for a command. Problem noted by David Endler of 173110560Sgshapiro iDEFENSE, Inc. 174110560Sgshapiro New Files: 175110560Sgshapiro devtools/OS/Interix 176110560Sgshapiro include/sm/bdb.h 177110560Sgshapiro 178102528Sgshapiro8.12.6/8.12.6 2002/08/26 179102528Sgshapiro Do not add the FallbackMXhost (or its MX records) to the list 180102528Sgshapiro returned by the bestmx map when -z is used as option. 181102528Sgshapiro Otherwise sendmail may act as an open relay if FallbackMXhost 182102528Sgshapiro and FEATURE(`relay_based_on_MX') are used together. 183102528Sgshapiro Problem noted by Alexander Ignatyev. 184102528Sgshapiro Properly split owner- mailing list messages when SuperSafe is set 185102528Sgshapiro to interactive. Problem noted by Todd C. Miller of 186102528Sgshapiro Courtesan Consulting. 187102528Sgshapiro Make sure that an envelope is queued in the selected queue group 188102528Sgshapiro even if some recipients are deleted or invalid. Problem 189102528Sgshapiro found by Chris Adams of HiWAAY Informations Services. 190102528Sgshapiro Do not send a bounce message if a message is completely collected 191102528Sgshapiro from the SMTP client. Problem noted by Kari Hurtta of the 192102528Sgshapiro Finnish Meteorological Institute. 193102528Sgshapiro Provide an 'install-submit-st' target for sendmail/Makefile to 194102528Sgshapiro install the MSP statistics file using the file named in the 195102528Sgshapiro confMSP_STFILE devtools variable. Requested by Jeff 196102528Sgshapiro Earickson of Colby College. 197102528Sgshapiro Queue up mail with a temporary error if setusercontext() fails 198102528Sgshapiro during a delivery attempt. Patch from Todd C. Miller of 199102528Sgshapiro Courtesan Consulting. 200102528Sgshapiro Fix handling of base64 encoded client authentication data for 201102528Sgshapiro SMTP AUTH. Patch from Elena Slobodnik of life medien GmbH. 202102528Sgshapiro Set the OpenLDAP option LDAP_OPT_RESTART so the client libraries 203102528Sgshapiro restart interrupted system calls. Problem noted by Luiz 204102528Sgshapiro Henrique Duma of BSIOne. 205102528Sgshapiro Prevent a segmentation fault if a program passed a NULL envp using 206102528Sgshapiro execve(). 207102528Sgshapiro Document a problem with the counting of queue runners that may 208102528Sgshapiro cause delays if MaxQueueChildren is set too low. Problem 209102528Sgshapiro noted by Ian Duplisse of Cable Television Laboratories, Inc. 210102528Sgshapiro If discarding a message based on a recipient, don't try to look up 211102528Sgshapiro the recipient in the mailbox database if F=w is set. This 212102528Sgshapiro allows users to discard bogus recipients when dealing with 213102528Sgshapiro spammers without tipping them off. Problem noted by Neil 214102528Sgshapiro Rickert of Northern Illinois University. 215102528Sgshapiro If applying a header check to a header with unstructured data, 216102528Sgshapiro e.g., Subject:, then do not run syntax checks that are 217102528Sgshapiro supposed for addresses on the header content. 218102528Sgshapiro Count messages rejected/discarded via the check_data ruleset. 219102528Sgshapiro Portability: 220102528Sgshapiro Fix compilation on systems which do not allow simple 221102528Sgshapiro copying of the variable argument va_list. Based on 222102528Sgshapiro fix from Scott Walters. 223102528Sgshapiro Fix NSD map open bug. From Michel Bourget of SGI. 224102528Sgshapiro Add some additional IRIX shells to the default shell 225102528Sgshapiro list. From Michel Bourget of SGI. 226102528Sgshapiro Fix compilation issues on Mac OS X 10.2 (Darwin 6.0). 227102528Sgshapiro NETISO support has been dropped. 228102528Sgshapiro CONFIG: There was a seemingly minor change in 8.12.4 with respect 229102528Sgshapiro to handling entries of IP nets/addresses with RHS REJECT. 230102528Sgshapiro These would be rejected in check_rcpt instead of only 231102528Sgshapiro being activated in check_relay. This change has been made to 232102528Sgshapiro avoid potential bogus temporary rejection of relay attempts 233102528Sgshapiro "450 4.7.1 Relaying temporarily denied. Cannot resolve PTR 234102528Sgshapiro record for ..." if delay_checks is enabled. However, this 235102528Sgshapiro modification causes a change of behavior if an IP net/address 236102528Sgshapiro is listed in the access map with REJECT and a host/domain 237102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 238102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 239102528Sgshapiro change was made on request of Neil Rickert of Northern 240102528Sgshapiro Illinois University, the side effect has been found by 241102528Sgshapiro Stefaan Van Hoornick. 242102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 243102528Sgshapiro using the local hostname ($j) or domains in class {P}. 244102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 245102528Sgshapiro University. 246102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 247102528Sgshapiro Fix from Andrzej Filip. 248102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 249102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 250102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 251102528Sgshapiro NULL pointer. Problem noted by Andrey J. Melnikoff. 252102528Sgshapiro LIBMILTER: Protect against more interrupted select() calls. Based 253102528Sgshapiro on patch from Jose Marcio Martins da Cruz of Ecole Nationale 254102528Sgshapiro Superieure des Mines de Paris. 255102528Sgshapiro New Files: 256102528Sgshapiro contrib/etrn.0 257102528Sgshapiro 25898841Sgshapiro8.12.5/8.12.5 2002/06/25 25998841Sgshapiro SECURITY: The DNS map can cause a buffer overflow if the user 26098841Sgshapiro specifies a dns map using TXT records in the configuration 26198841Sgshapiro file and a rogue DNS server is queried. None of the 26298841Sgshapiro sendmail supplied configuration files use this option hence 26398841Sgshapiro they are not vulnerable. Problem noted independently by 26498841Sgshapiro Joost Pol of PINE Internet and Anton Rang of Sun Microsystems. 26598841Sgshapiro Unprintable characters in responses from DNS servers for the DNS 26698841Sgshapiro map type are changed to 'X' to avoid potential problems 26798841Sgshapiro with rogue DNS servers. 26898841Sgshapiro Require a suboption when setting the Milter option. Problem noted 26998841Sgshapiro by Bryan Costales. 27098841Sgshapiro Do not silently overwrite command line settings for 27198841Sgshapiro DirectSubmissionModifiers. Problem noted by Bryan 27298841Sgshapiro Costales. 27398841Sgshapiro Prevent a segmentation fault when clearing the event list by 27498841Sgshapiro turning off alarms before checking if event list is 27598841Sgshapiro empty. Problem noted by Allan E Johannesen of Worcester 27698841Sgshapiro Polytechnic Institute. 27798841Sgshapiro Close a potential race condition in transitioning a memory buffered 27898841Sgshapiro file onto disk. From Janani Devarajan of Sun Microsystems. 27998841Sgshapiro Portability: 28098841Sgshapiro Include paths.h on Linux systems running glibc 2.0 or later 28198841Sgshapiro to get the definition for _PATH_SENDMAIL, used by 28298841Sgshapiro rmail and vacation. Problem noted by Kevin 28398841Sgshapiro A. McGrail of Peregrine Hardware. 28498841Sgshapiro NOTE: Linux appears to have broken flock() again. Unless 28598841Sgshapiro the bug is fixed before sendmail 8.13 is shipped, 28698841Sgshapiro 8.13 will change the default locking method to 28798841Sgshapiro fcntl() for Linux kernel 2.4 and later. You may 28898841Sgshapiro want to do this in 8.12 by compiling with 28998841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 29098841Sgshapiro related programs to match locking techniques. 29198841Sgshapiro 29298121Sgshapiro8.12.4/8.12.4 2002/06/03 29398121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 29498121Sgshapiro can leave systems open to a local denial of service 29598121Sgshapiro attack. Be sure to read the "FILE AND MAP PERMISSIONS" 29698121Sgshapiro section of the top level README for more information. 29798121Sgshapiro Problem noted by lumpy. 29898121Sgshapiro Use TempFileMode (defaults to 0600) for the permissions of PidFile 29998121Sgshapiro instead of 0644. 30098121Sgshapiro Change the default file permissions for new alias database files 30198121Sgshapiro from 0644 to 0640. This can be overridden at compile time 30298121Sgshapiro by setting the DBMMODE macro. 30398121Sgshapiro Fix a potential core dump problem if the environment variable 30498121Sgshapiro NAME is set. Problem noted by Beth A. Chaney of 30598121Sgshapiro Purdue University. 30698121Sgshapiro Expand macros before passing them to libmilter.

In previous versions this could cause mail 38894334Sgshapiro not to be delivered if a queue file is repeatedly moved 38994334Sgshapiro by an external process whenever sendmail moved it back 39094334Sgshapiro into the right place. Some precautions have been taken 39194334Sgshapiro to avoid moving queue files if not really necessary. 39294334Sgshapiro sendmail may use links to refer to queue files and it 39394334Sgshapiro may store the path of data files in queue files. Hence 39494334Sgshapiro queue files should not be moved unless those internals 39594334Sgshapiro are understood and the integrity of the files is not 39694334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 39794334Sgshapiro University. 39894334Sgshapiro If an error mail is created, and the mail is split across different 39994334Sgshapiro queue directories, and SuperSafe is off, then write the mail 40094334Sgshapiro to disk before splitting it, otherwise an assertion is 40194334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 40294334Sgshapiro of INTERMETA. 40394334Sgshapiro Fix possible race condition that could cause sendmail to forget 40494334Sgshapiro running queues.

Problem 44994334Sgshapiro found by Mario Nigrovic. 45094334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 45194334Sgshapiro incoming messages. A leading dot is always stripped by the 45294334Sgshapiro SMTP receiver regardless of whether or not it is followed by 45394334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 45494334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 45594334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 45694334Sgshapiro Elvers. 45794334Sgshapiro Correct the statistics gathered for total number of connections. 45894334Sgshapiro Instead of being the exact same number as the total number 45994334Sgshapiro of messages (T line in mailstats) it now represents the 46094334Sgshapiro total number of TCP connections. 46194334Sgshapiro Be more explicit about syntax errors in addresses, especially 46294334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 46394334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 46494334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 46594334Sgshapiro are used.

Based on 47394334Sgshapiro patch by Bryan Costales. 47494334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 47594334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 47694334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 47794334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 47894334Sgshapiro errors. By doing so, the host was marked as having a 47994334Sgshapiro temporary problem and other mail destined for that host was 48094334Sgshapiro queued for the next queue run. Problem noted by Fletcher 48194334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 48294334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 48394334Sgshapiro and Neil Rickert of Northern Illinois University. 48494334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 48594334Sgshapiro which drop the connection instead of responding to the 48694334Sgshapiro command). 48794334Sgshapiro Portability: 48894334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 48998121Sgshapiro available. 49094334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 49194334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 49294334Sgshapiro settings. Patch from Elias Halldor Agustsson of 49394334Sgshapiro Skyrr. 49494334Sgshapiro Fix dependency building on Mac OS X and Darwin. Problem 49594334Sgshapiro noted by John Beck. 49694334Sgshapiro Preliminary support for the sparc64 port of FreeBSD 5.0. 49794334Sgshapiro Add /sbin/sh as an acceptable user shell on HP-UX.

This feature was actually added in 50194334Sgshapiro 8.12.0 but a release note was not included. 50294334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 50394334Sgshapiro parameter is set and the LDAP lookup returns a temporary 50494334Sgshapiro error. 50594334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 50694334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 50794334Sgshapiro Krzysztof Oledzki. 50894334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 50994334Sgshapiro initialization as aliases are not needed for the MSP. 51094334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 51194334Sgshapiro is in use. Patch from Andrzej Filip. 51294334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 51394334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 51494334Sgshapiro This will only have an effect if a parameter is specified, 51594334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 51694334Sgshapiro it is embedded in square brackets. Problem noted by 51794334Sgshapiro Theo Van Dinter of Collective Technologies. 51894334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 51994334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 52094334Sgshapiro to allow for the proper time zone on systems where the 52194334Sgshapiro default results in misleading time stamps. That is, syslog 52294334Sgshapiro time stamps and Date headers on submitted mail will use the 52394334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 52494334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 52594334Sgshapiro by Neil Rickert of Northern Illinois University. 52694334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 52794334Sgshapiro binary. Adjust local mailer flags accordingly. Problem 52894334Sgshapiro noted by John Beck. 52994334Sgshapiro CONTRIB: Add a warning to qtool.pl to not move queue files around 53094334Sgshapiro if queue groups are used. 53194334Sgshapiro CONTRIB: buildvirtuser: Add -f option to force rebuild. 53294334Sgshapiro CONTRIB: smcontrol.pl: Add -f option to specify control socket. 53394334Sgshapiro CONTRIB: smcontrol.pl: Add support for 'memdump' command. 53494334Sgshapiro Suggested by Bryan Costales. 53594334Sgshapiro DEVTOOLS: Add dependency generation for test programs. 53694334Sgshapiro LIBMILTER: Remove conversion of port number for the socket 53794334Sgshapiro structure that is passed to xxfi_connect(). Notice: 53898121Sgshapiro this fix requires that sendmail and libmilter both have 53998121Sgshapiro this change; mixing versions may lead to wrong port 54094334Sgshapiro values depending on the endianness of the involved systems. 54194334Sgshapiro Problem noted by Gisle Aas of ActiveState. 54294334Sgshapiro LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but 54394334Sgshapiro SMFI_REJECT is returned, ignore the custom reply. Do the 54494334Sgshapiro same if '5XX' is used and SMFI_TEMPFAIL is returned. 54594334Sgshapiro LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as 54694334Sgshapiro required by mfapi.h. Problem noted by Jose Marcio Martins 54794334Sgshapiro da Cruz of Ecole Nationale Superieure des Mines de Paris. 54894334Sgshapiro LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set 54994334Sgshapiro this to 1 if your LDAP client libraries include 55094334Sgshapiro ldap_memfree(). 55194334Sgshapiro LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X 55294334Sgshapiro and NDBM on systems with the O_EXLOCK open(2) flag. 55394334Sgshapiro SMRSH: Fix compilation problem on some operating systems.

You need to create a new user and 78990792Sgshapiro a new group before installing sendmail (both called smmsp by 79090792Sgshapiro default). The installation process tries to install 79190792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 79290792Sgshapiro default.

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

From Per Hedeland of 186566494Sgshapiro Ericsson. 186666494Sgshapiro CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for 186766494Sgshapiro SMTP to all *smtp* mailers and those for RELAY to the relay 186866494Sgshapiro mailer as described in cf/README. 186966494Sgshapiro MAIL.LOCAL: Open the mailbox as the recipient not root so quotas 187066494Sgshapiro are obeyed. Problem noted by Damian Kuczynski of NIK. 187166494Sgshapiro MAKEMAP: Do not change a map's owner to the TrustedUser if using 187266494Sgshapiro makemap to 'unmake' the map. 187366494Sgshapiro RMAIL: Avoid overflowing the list of recipients being passed to 187466494Sgshapiro sendmail. 187566494Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 187666494Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 187766494Sgshapiro Meteorological Institute. 187866494Sgshapiro VACATION: Read the complete message to avoid "broken pipe" signals. 187966494Sgshapiro VACATION: Do not cut off vacation.msg files which have a single 188066494Sgshapiro dot as the only character on the line. 188166494Sgshapiro New Files: 188266494Sgshapiro cf/ostype/solaris8.m4 188366494Sgshapiro 188464562Sgshapiro8.11.0/8.11.0 2000/07/19 188564562Sgshapiro SECURITY: If sendmail is installed as a non-root set-user-ID binary 188664562Sgshapiro (not the normal case), some operating systems will still 188764562Sgshapiro keep a saved-uid of the effective-uid when sendmail tries 188864562Sgshapiro to drop all of its privileges. If sendmail needs to drop 188964562Sgshapiro these privileges and the operating system doesn't set the 189064562Sgshapiro saved-uid as well, exit with an error. Problem noted by 189164562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 189264562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 189364562Sgshapiro it populates. It is possible that some broken 189464562Sgshapiro implementations of snprintf() exist that do not do this. 189564562Sgshapiro Systems in this category should compile with 189664562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 189764562Sgshapiro system and report broken implementations to 189864562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 189964562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 190064562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 190164562Sgshapiro Implementation influenced by the example programs of 190264562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 190364562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 190464562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 190564562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 190664562Sgshapiro cf/README and doc/op/op.*. 190764562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 190864562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 190964562Sgshapiro ${server_name}, and ${server_addr}. These are documented 191064562Sgshapiro in cf/README and doc/op/op.*. 191164562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 191264562Sgshapiro random data. 191364562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 191464562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 191564562Sgshapiro try to use STARTTLS despite the security problems. 191664562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 191764562Sgshapiro support encryption. Based on code contributed by Tim 191864562Sgshapiro Martin of CMU. 191964562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 192064562Sgshapiro strength factor. 192164562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 192264562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 192364562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 192464562Sgshapiro of CMU. 192564562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 192664562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 192764562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 192864562Sgshapiro Fix the default family selection for DaemonPortOptions. As 192964562Sgshapiro documented, unless a family is specified in a 193064562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 193164562Sgshapiro also the default if no DaemonPortOptions value is set. 193264562Sgshapiro Therefore, IPv6 users should configure additional sockets 193364562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 193464562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 193564562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 193664562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 193764562Sgshapiro the interface information for an outgoing connection. 193864562Sgshapiro Not doing so was creating a mismatch between the socket 193964562Sgshapiro family and address used in subsequent connections if the 194064562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 194164562Sgshapiro by John Beck of Sun Microsystems. 194264562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 194364562Sgshapiro family based on the IP address. ${if_family} is no longer 194464562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 194564562Sgshapiro of Sun Microsystems. 194664562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 194764562Sgshapiro macros for both the incoming interface address/family and 194864562Sgshapiro the outgoing interface address/family. In order for M=b 194964562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 195064562Sgshapiro the incoming information in the queue file for later 195164562Sgshapiro delivery attempts. 195264562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 195364562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 195464562Sgshapiro smoe.org. 195564562Sgshapiro Add more vigilance in checking for putc() errors on output streams 195664562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 195764562Sgshapiro noted by Graeme Hewson of Oracle. 195864562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 195964562Sgshapiro Problem noted by Ajay Matia. 196064562Sgshapiro Under certain circumstances, an address could be listed as deferred 196164562Sgshapiro but would be bounced back to the sender as failed to be 196264562Sgshapiro delivered when it really should have been queued. Problem 196364562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 196464562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 196564562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 196664562Sgshapiro Hedeland of Ericsson. 196764562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 196864562Sgshapiro is defined to avoid a core dump due to incompatibilities 196964562Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 197064562Sgshapiro of Northern Illinois University. 197164562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 197264562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 197364562Sgshapiro Convert the free disk space shown in a control socket status query 197464562Sgshapiro to kilobyte units. 197564562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 197664562Sgshapiro looking up the hostname, requeue the message for a later 197764562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 197864562Sgshapiro Polytechnic. 197964562Sgshapiro Under the proper circumstances, failed connections would be recorded 198064562Sgshapiro as "Bad file number" instead of "Connection failed" in the 198164562Sgshapiro queue file and persistent host status. Problem noted by 198264562Sgshapiro Graeme Hewson of Oracle. 198364562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 198464562Sgshapiro within the hoststatus directory (e.g., lost+found). 198564562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 198664562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 198764562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 198864562Sgshapiro If a message data file can't be opened at delivery time, panic and 198964562Sgshapiro abort the attempt instead of delivering a message that 199064562Sgshapiro states "<<< No Message Collected >>>". 199164562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 199264562Sgshapiro restrictive. Problem noted by Mark G. Thomas of Mark 199364562Sgshapiro G. Thomas Consulting. 199464562Sgshapiro Preserve source port number instead of replacing it with the ident 199564562Sgshapiro port number (113). 199664562Sgshapiro Document the queue status characters in the mailq man page. 199764562Sgshapiro Suggested by Ulrich Windl of the Universitat Regensburg. 199864562Sgshapiro Process queued items in which none of the recipient addresses have 199964562Sgshapiro host portions (or there are no recipients). Problem noted 200064562Sgshapiro by Valdis Kletnieks of Virginia Tech. 200164562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 200264562Sgshapiro only the first to open the connection is allowed to close 200364562Sgshapiro it so a later map close doesn't break the connection for 200464562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 200564562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 200664562Sgshapiro authentication. Patch from Rainer Schoepf of the 200764562Sgshapiro University of Mainz. 200864562Sgshapiro Provide workaround for inconsistent handling of data passed 200964562Sgshapiro via callbacks to Cyrus SASL prior to version 1.5.23. 201064562Sgshapiro Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.

From Jun 201564562Sgshapiro Kuriyama of IMG SRC, Inc. and the FreeBSD Project. 201664562Sgshapiro Replace code for finding the number of CPUs on HPUX. 201764562Sgshapiro NCRUNIX MP-RAS 3.02 SO_REUSEADDR socket option does not 201864562Sgshapiro work properly causing problems if the accept() 201964562Sgshapiro fails and the socket needs to be reopened. Patch 202064562Sgshapiro from Tom Moore of NCR. 202164562Sgshapiro NetBSD uses a .0 extension of formatted man pages. From 202266494Sgshapiro Andrew Brown of Crossbar Security. 202364562Sgshapiro Return to using the IPv6 AI_DEFAULT flag instead of AI_V4MAPPED 202464562Sgshapiro for calls to getipnodebyname(). The Linux 202564562Sgshapiro implementation is broken so AI_ADDRCONFIG is stripped 202664562Sgshapiro under Linux.

This option and 226564562Sgshapiro its use is deprecated and will be removed from a future 226664562Sgshapiro version of sendmail. 226764562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 226864562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 226964562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 227064562Sgshapiro (IdS). 227164562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 227264562Sgshapiro a large number of files. See cf/README for more details. 227364562Sgshapiro The directory structure of the distribution has changed slightly 227464562Sgshapiro for easier code sharing among the programs. 227564562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 227664562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 227764562Sgshapiro which hold the client's authentication credentials, 227864562Sgshapiro the mechanism used for authentication, and the 227964562Sgshapiro authorization identity (i.e., the AUTH= parameter if 228064562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 228164562Sgshapiro On systems which use the Torek stdio library (all of the BSD 228264562Sgshapiro distributions), use memory-buffered files to reduce 228364562Sgshapiro file system overhead by not creating temporary files on 228464562Sgshapiro disk. Contributed by Exactis.com, Inc. 228564562Sgshapiro New option DataFileBufferSize to control the maximum size of a 228664562Sgshapiro memory-buffered data (df) file before a disk-based file is 228764562Sgshapiro used. Contributed by Exactis.com, Inc. 228864562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 228964562Sgshapiro memory-buffered transcript (xf) file before a disk-based 229064562Sgshapiro file is used. Contributed by Exactis.com, Inc. 229164562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 229264562Sgshapiro now listen on several different ports. Use: 229364562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 229464562Sgshapiro to run a Message Submission Agent (MSA); this is turned 229564562Sgshapiro on by default in m4-generated .cf files; it can be turned 229664562Sgshapiro off with FEATURE(`no_default_msa'). 229764562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 229864562Sgshapiro begin using RFC 2476 Message Submission for initial user 229964562Sgshapiro message submission. XUSR may disappear from a future release. 230064562Sgshapiro The new '-G' (relay (gateway) submission) command line option 230164562Sgshapiro indicates that the message being submitted from the command 230264562Sgshapiro line is for relaying, not initial submission. This means 230364562Sgshapiro the message will be rejected if the addresses are not fully 230464562Sgshapiro qualified and no canonicalization will be done. Future 230564562Sgshapiro releases may even reject improperly formed messages. 230664562Sgshapiro The '-U' (initial user submission) command line option is 230764562Sgshapiro deprecated and may be removed from a future release. 230864562Sgshapiro Mail user agents should begin using '-G' to indicate that 230964562Sgshapiro this is a relay submission (the inverse of -U). 231064562Sgshapiro The next release of sendmail will assume that any message submitted 231164562Sgshapiro from the command line is an initial user submission and act 231264562Sgshapiro accordingly. 231364562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 231464562Sgshapiro program or deliver to file as the owner of that file, the 231564562Sgshapiro address is marked as unsafe. This means if RunAsUser is 231664562Sgshapiro set, users won't be able to use programs or delivery to 231764562Sgshapiro files in their .forward files. Administrators can override 231864562Sgshapiro this by setting the DontBlameSendmail option to the new 231964562Sgshapiro setting NonRootSafeAddr. 232064562Sgshapiro Allow group or world writable directories if the sticky bit is set 232164562Sgshapiro on the directory and DontBlameSendmail is set to 232264562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 232364562Sgshapiro InCert Software. 232464562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 232564562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 232664562Sgshapiro set in the DontBlameSendmail option. Requested by many. 232764562Sgshapiro New Timeout.control option to limit the total time spent satisfying 232864562Sgshapiro a control socket request. 232964562Sgshapiro New Timeout.resolver options for controlling BIND resolver 233064562Sgshapiro settings: 233164562Sgshapiro Timeout.resolver.retrans 233264562Sgshapiro Sets the resolver's retransmission time interval (in 233364562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 233464562Sgshapiro and Timeout.resolver.retrans.normal. 233564562Sgshapiro Timeout.resolver.retrans.first 233664562Sgshapiro Sets the resolver's retransmission time interval (in 233764562Sgshapiro seconds) for the first attempt to deliver a message. 233864562Sgshapiro Timeout.resolver.retrans.normal 233964562Sgshapiro Sets the resolver's retransmission time interval (in 234064562Sgshapiro seconds) for all resolver lookups except the first 234164562Sgshapiro delivery attempt. 234264562Sgshapiro Timeout.resolver.retry 234364562Sgshapiro Sets the number of times to retransmit a resolver 234464562Sgshapiro query. Sets both Timeout.resolver.retry.first 234564562Sgshapiro and Timeout.resolver.retry.normal. 234664562Sgshapiro Timeout.resolver.retry.first 234764562Sgshapiro Sets the number of times to retransmit a resolver 234864562Sgshapiro query for the first attempt to deliver a message. 234964562Sgshapiro Timeout.resolver.retry.normal 235064562Sgshapiro Sets the number of times to retransmit a resolver 235164562Sgshapiro query for all resolver lookups except the first 235264562Sgshapiro delivery attempt. 235364562Sgshapiro Contributed by Exactis.com, Inc. 235464562Sgshapiro Support multiple queue directories. To use multiple queues, supply 235564562Sgshapiro a QueueDirectory option value ending with an asterisk. For 235664562Sgshapiro example, /var/spool/mqueue/q* will use all of the 235764562Sgshapiro directories or symbolic links to directories beginning with 235864562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 235964562Sgshapiro mind, the queue directory structure should not be changed 236064562Sgshapiro while sendmail is running. Queue runs create a separate 236164562Sgshapiro process for running each queue unless the verbose flag is 236264562Sgshapiro given on a non-daemon queue run. New items are randomly 236364562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 236464562Sgshapiro Support different directories for qf, df, and xf queue files; if 236564562Sgshapiro subdirectories or symbolic links to directories of those names 236664562Sgshapiro exist in the queue directories, they are used for the 236764562Sgshapiro corresponding queue files. Keep in mind, the queue 236864562Sgshapiro directory structure should not be changed while sendmail is 236964562Sgshapiro running. Proposed by Mathias Koerber of Singapore 237064562Sgshapiro Telecommunications Ltd. 237164562Sgshapiro New queue file naming system which uses a filename guaranteed to be 237264562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 237364562Sgshapiro without fancy file system locking. Queued items can be 237464562Sgshapiro moved between queues easily. Contributed by Exactis.com, 237564562Sgshapiro Inc. 237664562Sgshapiro Messages which are undeliverable due to temporary address failures 237764562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 237864562Sgshapiro set. Contributed by Exactis.com, Inc. 237964562Sgshapiro New command line option '-L tag' which sets the identifier used for 238064562Sgshapiro syslog. Contributed by Exactis.com, Inc. 238164562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 238264562Sgshapiro avoids opening and reading each queue file when preparing 238364562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 238464562Sgshapiro Shared memory counters and microtimers functionality has been 238564562Sgshapiro donated by Exactis.com, Inc. 238664562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 238764562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 238864562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 238964562Sgshapiro being added. Suggested by Michael K. Sanders. 239064562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 239164562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 239264562Sgshapiro and John Beck of Sun Microsystems. 239364562Sgshapiro In low-disk space situations, where sendmail would previously refuse 239464562Sgshapiro connections, still accept them, but only allow ETRN commands. 239564562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 239664562Sgshapiro Ltd. 239764562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 239864562Sgshapiro on systems which support them. This can be used with LMTP 239964562Sgshapiro local delivery agents which listen on a named socket. An 240064562Sgshapiro example mailer might be: 240164562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 240264562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 240364562Sgshapiro A=FILE /var/run/lmtpd 240464562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 240564562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 240664562Sgshapiro instead. 240764562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 240864562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 240964562Sgshapiro connections), IPC (which will be deprecated in a future 241064562Sgshapiro version), and FILE (for UNIX domain socket delivery). 241164562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 241264562Sgshapiro flags. 241364562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 241464562Sgshapiro body of the original message on delivery status 241564562Sgshapiro notifications. 241664562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 241764562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 241864562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 241964562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 242064562Sgshapiro Steve Schweinhart of America Online. 242164562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 242264562Sgshapiro not be set after rulesets are defined. Suggested by 242364562Sgshapiro Mitchell Blank Jr of Exec-PC. 242464562Sgshapiro Do not report temporary failure on delivery to files. In 242564562Sgshapiro interactive delivery mode, this would result in two SMTP 242664562Sgshapiro responses after the DATA command. Problem noted by 242764562Sgshapiro Nik Conwell of Boston University. 242864562Sgshapiro Check file close when mailing to files.

Hillegas of Princeton University. 243264562Sgshapiro Always bind to the LDAP server regardless of whether you are using 243364562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 243464562Sgshapiro @Home Network. 243564562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 243664562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 243764562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 243864562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 243964562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 244064562Sgshapiro similar to check_rcpt etc. 244164562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 244264562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 244364562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 244464562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 244564562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 244664562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 244764562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 244864562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 244964562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 245064562Sgshapiro the corresponding DSN parameter values. Proposed by 245164562Sgshapiro Mathias Herberts. 245264562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 245364562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 245464562Sgshapiro before the message has been collected, thereafter it holds 245564562Sgshapiro the message size as computed by sendmail (and can be used 245664562Sgshapiro in check_compat). 245764562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 245864562Sgshapiro sendmail is using instead of the value of the DeliveryMode 245964562Sgshapiro option. 246064562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 246164562Sgshapiro Drop explicit From: if same as what would be generated only if it is 246264562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 246364562Sgshapiro Write pid to file also if sendmail only processes the queue. 246464562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 246564562Sgshapiro Log "low on disk space" only when necessary. 246664562Sgshapiro New macro ${load_avg} can be used to check the current load average. 246764562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 246864562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 246964562Sgshapiro is set. 247064562Sgshapiro Flag -S for maps to specify the character which is substituted 247164562Sgshapiro for spaces (instead of the default given by O BlankSub). 247264562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 247364562Sgshapiro This flag is set by default for the host map. Based on a 247464562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 247564562Sgshapiro Open maps only on demand, not at startup. 247664562Sgshapiro Log warning about unsupported IP address families. 247764562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 247864562Sgshapiro of the sum of all headers. This can be used to prevent 247964562Sgshapiro a denial-of-service attack. 248064562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 248164562Sgshapiro headers and parameters within those headers. This option 248264562Sgshapiro is intended to protect mail user agents from buffer 248364562Sgshapiro overflow attacks. 248464562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 248564562Sgshapiro alias recursion. 248664562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 248764562Sgshapiro Map type syslog to log the key via syslogd. 248864562Sgshapiro Entries in the alias file can be continued by putting a backslash 248964562Sgshapiro directly before the newline. 249064562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 249164562Sgshapiro dead.letter file, formerly hardcoded to 249264562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 249364562Sgshapiro default), sendmail will not attempt to save to a 249464562Sgshapiro system-wide dead.letter file if it can not bounce the mail 249564562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 249664562Sgshapiro file as it has in the past when the dead.letter file 249764562Sgshapiro could not be opened. 249864562Sgshapiro New option PidFile to define the location of the pid file. The 249964562Sgshapiro value of this option is macro expanded. 250064562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 250164562Sgshapiro process title shown in 'ps' listings. 250264562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 250364562Sgshapiro (along with the already existing macros): 250464562Sgshapiro ${daemon_info} Daemon information, e.g. 250564562Sgshapiro SMTP+queueing@00:30:00 250664562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 250764562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 250864562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 250964562Sgshapiro ${daemon_port} Daemon port, e.g., 25 251064562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 251164562Sgshapiro New macros especially for virtual hosting: 251264562Sgshapiro ${if_name} hostname of interface of incoming connection. 251364562Sgshapiro ${if_addr} address of interface of incoming connection. 251464562Sgshapiro The latter is only set if the interface does not belong to the 251564562Sgshapiro loopback net. 251664562Sgshapiro If a message being accepted via a method other than SMTP and 251764562Sgshapiro would be rejected by a header check, do not send the message. 251864562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 251964562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 252064562Sgshapiro Provide header value as quoted string in the macro 252164562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 252264562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 252364562Sgshapiro The length of the header value is stored in ${hdrlen}. 252464562Sgshapiro H*: allows to specify a default ruleset for header checks. This 252564562Sgshapiro ruleset will only be called if the individual header does 252664562Sgshapiro not have its own ruleset assigned. Suggested by Jan 252764562Sgshapiro Krueger of Unix-AG of University of Hannover. 252864562Sgshapiro The name of the header field stored in ${hdr_name}. 252964562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 253064562Sgshapiro removed if the config file version is greater than or equal 253164562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 253264562Sgshapiro input "token (1)" but does not match "token". 253364562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 253464562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 253564562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 253664562Sgshapiro Ericsson. 253764562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 253864562Sgshapiro messages with 8-bit text in headers. Problem noted by 253964562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 254064562Sgshapiro of Ericsson. 254164562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 254264562Sgshapiro modified database map file. Problem noted by Chris Adams 254364562Sgshapiro of Renaissance Internet Services. 254464562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 254564562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 254664562Sgshapiro queue up the message instead of bouncing it. 254764562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 254864562Sgshapiro standard does not provide any indication of what to do when 254964562Sgshapiro something other than 250 is received. Based on a patch 255064562Sgshapiro from Steve Schweinhart of America Online. 255164562Sgshapiro New option TrustedUser allows to specify a user who can own 255264562Sgshapiro important files instead of root. This requires HASFCHOWN. 255364562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 255464562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 255564562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 255664562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 255764562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 255864562Sgshapiro $? tests also whether the macro is non-null. 255964562Sgshapiro Print an error message if a mailer definition contains an invalid 256064562Sgshapiro equate name. 256164562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 256264562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 256364562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 256464562Sgshapiro mailer to return after sending all data to it. 256564562Sgshapiro Only free memory from the process list when adding a new process 256664562Sgshapiro into a previously filled slot. Previously, the memory was 256764562Sgshapiro freed at removal time. Since removal can happen in a 256864562Sgshapiro signal handler, this may leave the memory map in an 256964562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 257064562Sgshapiro David Cooley of Colby College. 257164562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 257264562Sgshapiro local users in the passwd file. The UserDB code has 257364562Sgshapiro already decided the message will be passed to another host 257464562Sgshapiro for processing. Fix from Tony Landells of Burdett 257564562Sgshapiro Buckeridge Young Limited. 257664562Sgshapiro Support LDAP authorization via either a file containing the 257764562Sgshapiro password or Kerberos V4 using the new map options 257864562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 257964562Sgshapiro distinguished_name is who to login as. The method can be 258064562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 258164562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 258264562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 258364562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 258464562Sgshapiro of Stanford University. 258564562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 258664562Sgshapiro deprecated and will be removed in a future version. 258764562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 258864562Sgshapiro and the map has the column delimiter set, it turns that 258964562Sgshapiro response into a delimiter separated string. The LDAP map 259064562Sgshapiro will traverse multiple entries as well. LDAP alias maps 259164562Sgshapiro automatically set the column delimiter to the comma. 259264562Sgshapiro Based on patch from Booker Bense of Stanford University and 259364562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 259464562Sgshapiro Support return of multiple values for a single LDAP lookup. The 259564562Sgshapiro values to be returned should be in a comma separated string. 259664562Sgshapiro For example, `-v "email,emailother"'. Patch from 259764562Sgshapiro Curtis W. Hillegas of Princeton University. 259864562Sgshapiro Allow the use of LDAP for alias maps. 259964562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 260064562Sgshapiro attributes found in the match will be returned. 260164562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 260264562Sgshapiro breaking up a single entry into multiple entries. This is 260364562Sgshapiro needed for LDAP alias file specifications to allow for 260464562Sgshapiro comma separated key and value strings. 260564562Sgshapiro Keep connections to LDAP server open instead of opening and closing 260664562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 260764562Sgshapiro connections such that multiple maps which use the same 260864562Sgshapiro host, port, bind DN, and authentication will only result in 260964562Sgshapiro a single connection to that host. 261064562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 261164562Sgshapiro Be more careful about checking for errors and freeing memory on 261264562Sgshapiro LDAP lookups. 261364562Sgshapiro Use asynchronous LDAP searches to save memory and network 261464562Sgshapiro resources. 261564562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 261664562Sgshapiro Increase portability to the Netscape LDAP libraries. 261764562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 261864562Sgshapiro replaced with the literal contents of the map lookup key -- 261964562Sgshapiro note that this means a lookup can be done using the LDAP 262064562Sgshapiro special characters. The new '%0' token can be used instead 262164562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 262264562Sgshapiro For example, if the LDAP map specification contains '-k 262364562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 262464562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 262564562Sgshapiro user attribute. Instead, if the LDAP map specification 262664562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 262764562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 262864562Sgshapiro with the name "*". 262964562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 263064562Sgshapiro more than one is returned, it is equivalent to no records 263164562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 263264562Sgshapiro alias dereference option; "-Z size" limits the number of 263364562Sgshapiro matches to return. 263464562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 263564562Sgshapiro LDAP maps. The value should only contain LDAP specific 263664562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 263764562Sgshapiro settings will be used for all LDAP maps unless they are 263864562Sgshapiro specified in the individual map specification ('K' 263964562Sgshapiro command). This option should be set before any LDAP maps 264064562Sgshapiro are defined. 264164562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 264264562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 264364562Sgshapiro Tech. 264464562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 264564562Sgshapiro particular, class entries get much smaller, which can be 264664562Sgshapiro important if you have large classes. 264764562Sgshapiro On network-related temporary failures, record the hostname which 264864562Sgshapiro gave error in the queued status message. Requested by 264964562Sgshapiro Ulrich Windl of the Universitat Regensburg. 265064562Sgshapiro Add new F=% mailer flag to allow for a store and forward 265164562Sgshapiro configuration. Mailers which have this flag will not attempt 265271345Sgshapiro delivery on initial receipt of a message or on queue runs 265364562Sgshapiro unless the queued message is selected using one of the 265464562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 265564562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 265664562Sgshapiro New option ControlSocketName which, when set, creates a daemon 265764562Sgshapiro control socket. This socket allows an external program to 265864562Sgshapiro control and query status from the running sendmail daemon 265964562Sgshapiro via a named socket, similar to the ctlinnd interface to the 266064562Sgshapiro INN news server. Access to this interface is controlled by 266164562Sgshapiro the UNIX file permissions on the named socket on most UNIX 266264562Sgshapiro systems (see sendmail/README for more information). An 266364562Sgshapiro example control program is provided as contrib/smcontrol.pl. 266464562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 266564562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 266664562Sgshapiro number of processors online on the system (if that can be 266764562Sgshapiro determined). For single processor machines, this change 266864562Sgshapiro has no effect. 266964562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 267064562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 267164562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 267264562Sgshapiro Motonori Nakamura of Kyoto University. 267364562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 267464562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 267564562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 267664562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 267764562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 267864562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 267964562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 268064562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 268164562Sgshapiro connection-based denial of service attacks. 268264562Sgshapiro Log basic information about authenticated connections at LogLevel 268364562Sgshapiro 10 or higher. 268464562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 268564562Sgshapiro information (from= syslog line). 268664562Sgshapiro Log the DSN code for each recipient if one is available as a new 268764562Sgshapiro equate (dsn=). 268864562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 268964562Sgshapiro New "ph" map for performing ph queries in rulesets.

Contributed by Mark 269271345Sgshapiro Roth of the University of Illinois at Urbana-Champaign. 269364562Sgshapiro Detect temporary lookup failures in the host map if looking up a 269464562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 269564562Sgshapiro Finnish Meteorological Institute. 269664562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 269764562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 269864562Sgshapiro When a forward file points to an alias which runs a program, run 269964562Sgshapiro the program as the default user and the default group, not 270064562Sgshapiro the forward file user. This change also assures the 270164562Sgshapiro :include: directives in aliases are also processed using 270264562Sgshapiro the default user and group. Problem noted by Sergiu 270364562Sgshapiro Popovici of DNT Romania. 270464562Sgshapiro Prevent attempts to save a dead.letter file for a user with 270564562Sgshapiro no home directory (/no/such/directory). Problem noted by 270664562Sgshapiro Michael Brown of Finnigan FT/MS. 270764562Sgshapiro Include message delay and number of tries when logging that a 270864562Sgshapiro message has been completely delivered (LogLevel of 10 or 270964562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 271064562Sgshapiro Log the sender of a message even if none of the recipients were 271164562Sgshapiro accepted. If some of the recipients were rejected, it is 271264562Sgshapiro helpful to know the sender of the message. 271364562Sgshapiro Check the root directory (/) when checking a path for safety. 271464562Sgshapiro Problem noted by John Beck of Sun Microsystems. 271564562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 271664562Sgshapiro interactive and delivering to an alias which resolves to 271764562Sgshapiro multiple files. 271864562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 271964562Sgshapiro greater (see below); the help function doesn't print the 272064562Sgshapiro version of sendmail any longer, instead it is placed in 272164562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 272264562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 272364562Sgshapiro skipped and a version line (#vers) is introduced. The 272464562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 272564562Sgshapiro version is found, a warning is logged. The '#vers' 272664562Sgshapiro directive should be placed at the top of the help file. 272764562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 272864562Sgshapiro disk succeeded. Suggested by Nick Christenson. 272964562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 273064562Sgshapiro length before the attempt. 273164562Sgshapiro If a forward points to a filename for delivery, change to the 273264562Sgshapiro user's uid before checking permissions on the file. This 273364562Sgshapiro allows delivery to files on NFS mounted directories where 273464562Sgshapiro root is remapped to nobody. Problem noted by Harald 273564562Sgshapiro Daeubler of Universitaet Ulm. 273664562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 273764562Sgshapiro host status files, not all files. 273864562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 273964562Sgshapiro in the queue file for the message and set when delivery 274064562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 274164562Sgshapiro Wonderworks Inc. 274264562Sgshapiro Add support for storing information between rulesets using the new 274364562Sgshapiro macro map class. This can be used to store information 274464562Sgshapiro between queue runs as well using $={persistentMacros}. 274564562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 274664562Sgshapiro of Hannover. 274764562Sgshapiro New map class arith to allow for computations in rules. The 274864562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 274964562Sgshapiro as key. The two operands are specified as arguments; the 275064562Sgshapiro lookup returns the result of the computation. For example, 275164562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 275264562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 275364562Sgshapiro Add new syntax for header declarations which decide whether to 275464562Sgshapiro include the header based on a macro rather than a mailer 275564562Sgshapiro flag: 275664562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 275764562Sgshapiro This should be used along with $={persistentMacros}. 275864562Sgshapiro It can be used for adding headers to a message based on 275964562Sgshapiro the results of check_* and header check rulesets. 276064562Sgshapiro Allow new named config file rule check_eoh which is called after 276164562Sgshapiro all of the headers have been collected. The input to the 276264562Sgshapiro ruleset the number of headers and the size of all of the 276364562Sgshapiro headers in bytes separated by $|. This ruleset along with 276464562Sgshapiro the macro storage map can be used to correlate information 276564562Sgshapiro gathered between headers and to check for missing headers. 276664562Sgshapiro See cf/README or doc/op/op.ps for an example. 276764562Sgshapiro Change the default for the MeToo option to True to correspond 276864562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 276964562Sgshapiro option is deprecated and will be removed from a future 277064562Sgshapiro version. 277164562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 277264562Sgshapiro Change the sendmail binary default for SuperSafe to True. 277364562Sgshapiro Display ruleset names in debug and address test mode output 277464562Sgshapiro if referencing a named ruleset. 277564562Sgshapiro New mailer equate m= which will limit the number of messages 277664562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 277764562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 277864562Sgshapiro using it to sort. Now all the same domains are really run 277964562Sgshapiro through the queue together. If they have the same MX host, 278064562Sgshapiro then they will have a much better opportunity to use the 278164562Sgshapiro connection cache if available. This should be a reasonable 278264562Sgshapiro performance improvement. Patch from Randall Winchester of 278364562Sgshapiro the University of Maryland. 278464562Sgshapiro If a message is rejected by a header check ruleset, log who would 278564562Sgshapiro have received the message if it had not been rejected. 278664562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 278764562Sgshapiro queue immediately.

This is useful for sending mails 282964562Sgshapiro to hosts which have dynamically assigned names. 283064562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 283164562Sgshapiro the bounce for the same reason. If the body is not 8-bit 283264562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 283364562Sgshapiro not be included in the bounce. Problem noted by Valdis 283464562Sgshapiro Kletnieks of Virginia Tech. 283564562Sgshapiro The timeout for sending a message via SMTP has been changed from 283664562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 283764562Sgshapiro simply checks for progress on sending data every 5 minutes. 283864562Sgshapiro This will detect the inability to send information quicker 283964562Sgshapiro and reduce the number of processes simply waiting to 284064562Sgshapiro timeout. 284164562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 284264562Sgshapiro interface address structure when loading the system network 284364562Sgshapiro interface addresses.

Based on idea from Neil Rickert 291064562Sgshapiro of Northern Illinois University and patch from Per Hedeland 291164562Sgshapiro of Ericsson. 291264562Sgshapiro Report the proper UID in the bounce message if an :include: file is 291364562Sgshapiro owned by a uid that doesn't map to a username and the 291464562Sgshapiro :include: file contains delivery to a file or program. 291564562Sgshapiro Problem noted by John Beck of Sun Microsystems. 291664562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 291764562Sgshapiro the remote server responds to the first QUIT with a 4xx 291864562Sgshapiro response code and drops the connection. This behavior was 291964562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 292064562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 292164562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 292264562Sgshapiro file is not present, the lookup failure would be marked as 292364562Sgshapiro a permanent failure instead of a temporary failure. Fix 292464562Sgshapiro from Russell King of the ARM Linux Project. 292564562Sgshapiro Handle aliases or forwards which deliver to programs using tabs 292664562Sgshapiro instead of spaces between arguments. Problem noted by Randy 292764562Sgshapiro Wormser.

Problem noted 294464562Sgshapiro by Michal Zalewski of Marchew Industries. 294564562Sgshapiro Stop processing SMTP commands if the SMTP connection is dropped. 294664562Sgshapiro This prevents a remote system from flooding the connection 294764562Sgshapiro with commands and then disconnecting. Previously, the 294864562Sgshapiro server would process all of the buffered commands. Problem 294964562Sgshapiro noted by Michal Zalewski of Marchew Industries. 295064562Sgshapiro Properly process user-supplied headers beginning with '?'. Problem 295164562Sgshapiro noted by Michal Zalewski of Marchew Industries. 295264562Sgshapiro If multiple header checks resolve to the $#error mailer, use the 295364562Sgshapiro last permanent (5XX) failure if any exist. Otherwise, use 295464562Sgshapiro the last temporary (4XX) failure. 295564562Sgshapiro RFC 1891 requires "hexchar" in a "xtext" to be upper case. Patch 295664562Sgshapiro from Ronald F.

Suggested by many. 296064562Sgshapiro Persistent host status data is not reloaded disk when current data 296164562Sgshapiro is available in the in-memory cache. Problem noted by Per 296264562Sgshapiro Hedeland of Ericsson. 296364562Sgshapiro mailq displays unprintable characters in addresses as their octal 296464562Sgshapiro representation and a leading backslash. This avoids problems 296564562Sgshapiro with "unprintable" characters. Problem noted by Michal 296664562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 296764562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 296864562Sgshapiro one character past the limit. This would cause subsequent 296964562Sgshapiro hops to break the line again. The '!' is now placed in 297064562Sgshapiro the last column of the limit if the line needs to be broken. 297164562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 297264562Sgshapiro from Per Hedeland of Ericsson. 297364562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 297464562Sgshapiro resolver will fall back to TCP. However, some 297564562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 297664562Sgshapiro fails whereas an MX or A record might succeed. Therefore, 297764562Sgshapiro don't fail on ANY queries. 297864562Sgshapiro If an SMTP recipient is rejected due to syntax errors in the 297964562Sgshapiro address, do not send an empty postmaster notification DSN 298064562Sgshapiro to the postmaster.

This mail provides on-demand delivery using the 314464562Sgshapiro F=% mailer flag described above. The "dsmtp" mailer 314564562Sgshapiro definition uses the new DSMTP_MAILER_ARGS which defaults 314664562Sgshapiro to "IPC $h". 314764562Sgshapiro CONFIG: New variables LOCAL_MAILER_MAXMSGS, SMTP_MAILER_MAXMSGS, 314864562Sgshapiro and RELAY_MAILER_MAXMSGS for setting the m= equate for the 314964562Sgshapiro local, smtp, and relay mailers respectively. 315064562Sgshapiro CONFIG: New variable LOCAL_MAILER_DSN_DIAGNOSTIC_CODE for setting 315164562Sgshapiro the DSN Diagnostic-Code type for the local mailer. The 315264562Sgshapiro value should be changed with care. 315364562Sgshapiro CONFIG: FEATURE(`local_lmtp') now sets the DSN Diagnostic-Code type 315464562Sgshapiro for the local mailer to the proper value of "SMTP". 315564562Sgshapiro CONFIG: All included maps are no longer optional by default; if 315664562Sgshapiro there there is a problem with a map, sendmail will 315764562Sgshapiro complain. 315864562Sgshapiro CONFIG: Removed root from class E; use EXPOSED_USER(`root') 315964562Sgshapiro to get the old behavior. Suggested by Joe Pruett 316064562Sgshapiro of Q7 Enterprises. 316164562Sgshapiro CONFIG: MASQUERADE_EXCEPTION() defines hosts/subdomains which 316264562Sgshapiro will not be masqueraded.

Prindeville of Enteka Enterprise Technology 320564562Sgshapiro Services. 320664562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 320764562Sgshapiro names. Problem noted by Randall Winchester of Swales 320864562Sgshapiro Aerospace. 320964562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 321064562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 321164562Sgshapiro University and Brian Candler. 321264562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 321364562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 321464562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 321564562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 321664562Sgshapiro Institute. 321764562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 321864562Sgshapiro i.e., to set, add, or delete flags. 321964562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 322064562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 322164562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 322264562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 322364562Sgshapiro after check_rcpt and allows for exceptions from the checks. 322464562Sgshapiro CONFIG: Map declarations have been moved into their associated 322564562Sgshapiro feature files to allow greater flexibility in use of 322664562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 322764562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 322864562Sgshapiro line string for the local mailer. Requested by Il Oh of 322964562Sgshapiro Willamette Industries, Inc. 323064562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 323164562Sgshapiro converted to <user@d> 323264562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 323364562Sgshapiro Sun's older, broken configuration files. 323464562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 323564562Sgshapiro normal configuration, allowing anti-spam checks to be 323664562Sgshapiro performed. 323764562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 323864562Sgshapiro ${client_name} can't be resolved just temporarily. 323964562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 324064562Sgshapiro Institute. 324164562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 324264562Sgshapiro be accessed by their numbers). 324364562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 324464562Sgshapiro which describes whether to disallow "!" in the local part 324564562Sgshapiro of an address. 324664562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 324764562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 324864562Sgshapiro set. If the ruleset returns a mailer, the appropriate 324964562Sgshapiro action is taken, otherwise the returned tokens are ignored. 325064562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 325164562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 325264562Sgshapiro The latter is kept around for backward compatibility. 325364562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 325464562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 325564562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 325664562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 325764562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 325864562Sgshapiro Institute. 325964562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 326064562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 326164562Sgshapiro arguments overriding the mailer program, arguments, and 326264562Sgshapiro mailer definition flags. This makes it possible to use 326364562Sgshapiro other programs such as maildrop for local delivery. 326464562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 326564562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 326664562Sgshapiro Patch from Richard A. Nelson of IBM. 326764562Sgshapiro CONFIG: Add SMTP Authentication information to Received: header 326864562Sgshapiro default value (confRECEIVED_HEADER). 326964562Sgshapiro CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a 327064562Sgshapiro local mailer. Problem noted by Per Hedeland of Ericsson. 327164562Sgshapiro CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the 327264562Sgshapiro University of California at Berkeley. 327364562Sgshapiro CONTRIB: Added domainmap.m4 from Mark D.

Problem noted by Ezequiel H. Panepucci of 328264562Sgshapiro Yale University. 328364562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 328464562Sgshapiro be used for building. 328564562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 328664562Sgshapiro used for a fresh build. 328764562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 328864562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 328964562Sgshapiro ranlib. 329064562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 329164562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 329264562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 329364562Sgshapiro building of the man pages when defined. Suggested by Bryan 329464562Sgshapiro Costales. 329564562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 329664562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 329764562Sgshapiro installation of the sendmail helpfile and statistics file 329864562Sgshapiro respectively. Suggested by Bryan Costales. 329964562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 330064562Sgshapiro of Siemens Business Services. 330164562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 330264562Sgshapiro stdio library. The new buffered file I/O depends on the 330364562Sgshapiro Torek stdio library. This option can be either portable or 330464562Sgshapiro torek. 330564562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 330664562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 330764562Sgshapiro They should contain the C source files for the object files 330864562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 330964562Sgshapiro will be passed to the 'make depend' stage of compilation. 331064562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 331164562Sgshapiro in the sendmail distribution. Each has the form 331264562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 331364562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 331464562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 331564562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 331664562Sgshapiro building the distribution, but documentation on the changes 331764562Sgshapiro are in devtools/README. 331864562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 331964562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 332064562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 332164562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 332264562Sgshapiro new variable which identifies the root of the source 332364562Sgshapiro directories for all of the programs in the distribution. 332464562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 332564562Sgshapiro time. They can both still be overridden by setting the m4 332664562Sgshapiro macro. 332764562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 332864562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 332964562Sgshapiro build configurations, and places objects in obj.prefix.*/. 333064562Sgshapiro Complains as 'Build -f file' does for existing object 333164562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 333264562Sgshapiro Corporation. 333364562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 333464562Sgshapiro manual pages in the directory tree specified by 333564562Sgshapiro confMANROOTMAN. 333664562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 333764562Sgshapiro preformatted pages from the distribution. The new variable 333864562Sgshapiro confCOPY specifies the copying program. 333964562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 334064562Sgshapiro question. Suggested by Terry Lambert of Whistle 334164562Sgshapiro Communications. 334264562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 334364562Sgshapiro of the installed statistics and help files, respectively. 334464562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 334564562Sgshapiro operating system identity. Problem noted by Erik 334664562Sgshapiro Wachtenheim of Dartmouth College. 334764562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 334864562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 334964562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 335064562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 335164562Sgshapiro how to strip binaries. These are used by the new 335264562Sgshapiro install-strip target. 335364562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 335464562Sgshapiro the others (if it exists). 335564562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 335664562Sgshapiro then the default ones. 335790792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 335864562Sgshapiro as local delivery agent without LMTP mode, use 335964562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 336064562Sgshapiro to set the S flag. 336164562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 336264562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 336364562Sgshapiro Northern Illinois University. 336464562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 336564562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 336664562Sgshapiro the Finnish Meteorological Institute. 336764562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 336864562Sgshapiro MAILLOCK when compiling. Also requires linking with 336964562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 337064562Sgshapiro University. 337164562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 337264562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 337364562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 337464562Sgshapiro University. 337564562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 337664562Sgshapiro structure to the beginning of the program. This ensures that 337764562Sgshapiro the getservbyname() is done before any seteuid to a possibly 337864562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 337964562Sgshapiro on a Solaris system, this avoids syslog messages such as, 338064562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 338164562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 338264562Sgshapiro University. 338364562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 338464562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 338564562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 338664562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 338764562Sgshapiro characters (in LMTP mode), mail.local split the incoming 338864562Sgshapiro line up into 2046-character output lines (excluding the 338964562Sgshapiro newline).

Sites 388738032Speter which need the ability to override security can use the 388838032Speter DontBlameSendmail option. See the README file for more 388938032Speter information. 389038032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 389138032Speter if maps or alias files are in world writable directories. 389238032Speter This fixes the change added to 8.8.6 to prevent links in these 389338032Speter world writable directories. 389438032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 389538032Speter it is in a world writable directory. 389638032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 389738032Speter tty it may be able to push bytes back to the senders input. 389838032Speter Unfortunately this breaks -v mode.

If none of these exist, sendmail 390738032Speter reverts back to the old behavior of using uid 1 and gid 1. 390838032Speter This is a security problem for Linux which has chosen that 390938032Speter uid and gid for user bin instead of daemon. If DefaultUser 391038032Speter is set in the configuration file, that value overrides this 391138032Speter default. 391290792Sgshapiro SECURITY: Since 8.8.7, the check for non-set-user-ID binaries 391338032Speter interfered with setting an alternate group id for the 391438032Speter RunAsUser option.

After this number is reached, sendmail 395838032Speter starts returning "452 Too many recipients" to all RCPT 395938032Speter commands. This can be used to limit the number of recipients 396038032Speter per envelope (in particular, to discourage use of the server 396138032Speter for spamming). Note: a better approach is to restrict 396238032Speter relaying entirely. 396338032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 396438032Speter to ldapx map and added timeout for ldap_open call to 396538032Speter avoid hanging sendmail in the event of hung LDAP servers. 396638032Speter Patch from Booker Bense of Stanford University. 396738032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 399038032Speter of Procter & Gamble. 399138032Speter New DontBlameSendmail option. This option allows administrators to 399238032Speter bypass some of sendmail's file security checks at the expense 399338032Speter of system security.

In particular, if you 402938032Speter have lots of virtual interfaces, this option will speed up 403038032Speter startup.

If they differ or if the PTR lookup 404038032Speter fails, &{client_name} will contain the IP address 404164562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 404238032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 404338032Speter (i.e, it is like -ax for the temporary failure case, in 404438032Speter contrast to the success case). 404538032Speter New syntax to do limited checking of header syntax. A config line 404638032Speter of the form: 404738032Speter HHeader: $>Ruleset 404838032Speter causes the indicated Ruleset to be invoked on the Header 404938032Speter when read. This ruleset works like the check_* rulesets -- 405038032Speter that is, it can reject mail on the basis of the contents. 405138032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 405238032Speter from hiding their connection information in Received: 405338032Speter headers. 405438032Speter When SingleThreadDelivery is active, deliveries to locked hosts 405538032Speter are skipped. This will cause the delivering process to 405638032Speter try the next MX host or queue the message if no other MX 405738032Speter hosts are available. Suggested by Alexander Litvin. 405838032Speter The [FILE] mailer type now delivers to the file specified in the 405938032Speter A= equate of the mailer definition instead of $u. It also 406038032Speter obeys all of the F= mailer flags such as the MIME 406138032Speter 7/8 bit conversion flags. This is useful for defining 406238032Speter a mailer which delivers to the same file regardless of the 406364562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 406438032Speter Do not assume the identity of a remote connection is root@localhost 406538032Speter if the remote connection closes the socket before the 406638032Speter remote identity can be queried. 406738032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 406838032Speter Some mailers, including procmail, require that the real 406938032Speter uid is left unchanged by sendmail. Problem noted by Per 407038032Speter Hedeland of Ericsson. 407138032Speter No longer is the src/obj*/Makefile selected from a large list -- it 407238032Speter is now generated using the information in BuildTools/OS/ -- 407338032Speter some of the details are determined dynamically via 407438032Speter BuildTools/bin/configure.sh. 407538032Speter The other programs in the sendmail distribution -- mail.local, 407638032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 407738032Speter the new Build method which creates an operating system 407838032Speter specific Makefile using the information in BuildTools. 407938032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 408038032Speter a failure on one message won't affect future messages to the 408138032Speter same host). This is necessary if the remote host sends 408238032Speter a 451 error if the domain of the sender does not resolve 408338032Speter as is common in anti-spam configurations. Problem noted 408438032Speter by Mitchell Blank Jr of Exec-PC. 408538032Speter New "discard" mailer for check_* rulesets and header checking 408638032Speter rulesets. If one of the above rulesets resolves to the 408738032Speter $#discard mailer, the commands will be accepted but the 408838032Speter message will be completely discarded after it is accepting. 408938032Speter This means that even if only one of the recipients 409038032Speter resolves to the $#discard mailer, none of the recipients 409138032Speter will receive the mail. Suggested by Brian Kantor. 409238032Speter All but the last cloned envelope of a split envelope were queued 409338032Speter instead of being delivered.

The default is hash. Patch from 419738032Speter Robert Harker of Harker Systems. 419838032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 419938032Speter directory for certain programs. 420038032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 420138032Speter local mail delivery. By the default, /usr/libexec/mail.local 420238032Speter is used. This is expected to be the mail.local shipped 420338032Speter with 8.9 which is LMTP capable. The path is based on the 420438032Speter new confEBINDIR m4 variable. 420538032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 420638032Speter FEATURE(smrsh). Note that this changes the default from 420738032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 420838032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 420938032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 421038032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 421138032Speter the user to setup different .forward files for 421238032Speter user+detail addressing. 421338032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 421438032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 421538032Speter DontProbeInterfaces, and DontBlameSendmail options. 421638032Speter CONFIG: by default do not allow relaying (that is, accepting mail 421738032Speter from outside your domain and sending it to another host 421838032Speter outside your domain). 421938032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 422038032Speter any site to any site. 422138032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 422238032Speter domain as defined by the 'm' class ($=m) to relay. 422338032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 422438032Speter the MX records of the host portion of an incoming recipient. 422538032Speter CONFIG: new FEATURE(access_db) which turns on the access database 422677349Sgshapiro feature. This database gives you the ability to allow 422738032Speter or refuse to accept mail from specified domains for 422838032Speter administrative reasons. By default, names that are listed 422938032Speter as "OK" in the access db are domain names, not host names. 423038032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 423138032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 423238032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 423338032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 423438032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 423538032Speter of FEATURE(access_db) and class 'R' to lookup individual 423638032Speter host names only. 423738032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 423838032Speter using % addressing is used, e.g. user%site@othersite, 423938032Speter and othersite is in class 'R', the check_rcpt ruleset 424038032Speter will strip @othersite and recheck user@site for relaying. 424138032Speter This feature changes that behavior. It should not be 424238032Speter needed for most installations. 424338032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 424438032Speter domain portion of the mail sender is a local host. This 424538032Speter should only be used if absolutely necessary as it opens 424638032Speter a window for spammers. Patch from Randall S. Winchester of 424738032Speter the University of Maryland. 424838032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 424938032Speter block incoming mail destined for certain recipient 425038032Speter usernames, hostnames, or addresses. 425138032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 425238032Speter refused if the host part of the argument to MAIL FROM: cannot 425338032Speter be located in the host name service (e.g., DNS). 425438032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 425538032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 425638032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 425738032Speter MAIL FROM: senders which do not include a domain. 425838032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 425938032Speter Realtime Blackhole List. You can specify the RBL name 426038032Speter server to contact by specifying it as an optional argument. 426138032Speter The default is rbl.maps.vix.com. For details, see 426238032Speter http://maps.vix.com/rbl/. 426338032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 426438032Speter Local_check_rcpt from check_relay, check_mail, and 426538032Speter check_rcpt. Users with local rulesets should place the 426638032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 426738032Speter returns $#OK, the message is accepted. If the ruleset 426838032Speter returns a mailer, the appropriate action is taken, else 426938032Speter the return of the ruleset is ignored. 427038032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 427138032Speter default to support file, :include:, and program deliveries. 427238032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 427338032Speter pick the proper default value. See the SECURITY note 427438032Speter above for more information. 427538032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 427638032Speter no-op. Patch from Kari Hurtta of the Finnish 427738032Speter Meteorological Institute. 427838032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 427938032Speter daemon since DEC's /bin/mail will drop the envelope 428038032Speter sender if run as mailnull. See the Digital UNIX section 428138032Speter of src/README for more information. Problem noted by 428238032Speter Kari Hurtta of the Finnish Meteorological Institute. 428338032Speter CONFIG: .cf files are now stored in the same directory with the 428438032Speter .mc files instead of in the obj directory. 428564562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 428638032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 428738032Speter setting SingleLineFromHeader, AllowBogusHELO, and 428838032Speter MustQuoteChars respectively. 428938032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.

Problem noted by Kari Hurtta of the Finnish 440738032Speter Meteorological Institute. 440838032Speter If /usr/tmp/dead.letter already existed, sendmail could not 440938032Speter add additional bounces to it. Problem noted by Thomas J. 441038032Speter Arseneault of SRI International. 441138032Speter If an SMTP mailer used a non-standard port number for the outgoing 441238032Speter connection, it would be displayed incorrectly in verbose mode. 441338032Speter Problem noted by John Kennedy of Cal State University, Chico. 441438032Speter Log the ETRN parameter specified by the client before altering them 441538032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 441638032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 441738032Speter User unknown with bogus delay= values. Change them to log 441838032Speter the same as compliant addresses. Problem noted by Kari E. 441938032Speter Hurtta of the Finnish Meteorological Institute. 442038032Speter Ignore the debug resolver option unless using sendmail debug trace 442138032Speter option for resolver. Problem noted by Greg Nichols of Wind 442238032Speter River Systems. 442338032Speter If SingleThreadDelivery was enabled and the remote server returned a 442438032Speter protocol error on the DATA command, the connection would be 442538032Speter closed but the persistent host status file would not be 442638032Speter unlocked so other sendmail processes could not deliver to 442738032Speter that host. Problem noted by Peter Wemm of DIALix. 442838032Speter If queueing up a message due to an expensive mailer, don't increment 442938032Speter the number of delivery attempts or set the last delivery 443038032Speter attempt time so the message will be delivered on the next 443138032Speter queue run regardless of MinQueueAge. Problem noted by 443238032Speter Brian J. Coan of the Institute for Global Communications. 443338032Speter Authentication warnings of "Processed from queue _directory_" and 443438032Speter "Processed by _username_ with -C _filename_" would be logged 443538032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 443638032Speter of the Finnish Meteorological Institute. 443738032Speter Use a better heuristic for detecting GDBM. 443838032Speter Log null connections on dropped connections. Problem noted by 443938032Speter Jon Lewis of Florida Digital Turnpike. 444038032Speter If class dbm maps are rebuilt, sendmail will now detect this and 444138032Speter reopen the map. Previously, they could give stale 444238032Speter results during a single message processing (but would 444338032Speter recover when the next message was received). Fix from 444438032Speter Joe Pruett of Q7 Enterprises. 444538032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 444638032Speter requests. Problem noted by Kari E. Hurtta of the 444738032Speter Finnish Meteorological Institute. 444838032Speter Do not send a bounce message back to the sender regarding bad 444938032Speter recipients if the SMTP connection is dropped before the 445038032Speter message is accepted. Problem noted by Kari E. Hurtta of the 445138032Speter Finnish Meteorological Institute. 445238032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 445338032Speter sendmail via a UNIX pipe. This will allow rulesets using 445438032Speter $&{client_name} to process without sending the string through 445538032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 445638032Speter A combination of deferred delivery mode, a double bounce situation, 445738032Speter and the inability to save a bounce message to 445838032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 445938032Speter to postmaster but not remove the offending envelope from the 446038032Speter queue causing it to create a new bounce message each time the 446138032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 446238032Speter Associates. 446338032Speter Remove newlines from hostname information returned via DNS. There are 446438032Speter no known security implications of newlines in hostnames as 446538032Speter sendmail filters newlines in all vital areas; however, this 446638032Speter could cause confusing error messages. 446738032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 446838032Speter rejected if any of the specified addresses were bad. This 446938032Speter behavior was modified to only reject the bad addresses and not 447038032Speter the entire message. Problem noted by Jozsef Hollosi of 447138032Speter SuperNet, Inc. 447238032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 447338032Speter Bryan Costales of InfoBeat, Inc. 447438032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 447538032Speter mailers. Problem noted by Kari E. Hurtta of the 447638032Speter Finnish Meteorological Institute. 447738032Speter An error in calculating the available space in the list of addresses 447838032Speter for logging deliveries could cause an address to be silently 447938032Speter dropped. 448038032Speter Include the initial user environment if sendmail is restarted via 448138032Speter a HUP signal. This will give room for the process title. 448238032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 448338032Speter Mail could be delivered without a body if the machine does not 448438032Speter support flock locking and runs out of processes during 448538032Speter delivery. Fix from Chuck Lever of the University of Michigan. 448638032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 448738032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 448838032Speter Institute. 448938032Speter Make sure non-rebuildable database maps are opened before the 449064562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 449138032Speter are needed for verifying the left hand side of the aliases. 449238032Speter Problem noted by Lloyd Parkes of Victoria University. 449338032Speter Make sure sender RFC822 source route addresses are alias expanded for 449438032Speter bounce messages. Problem noted by Juergen Georgi of 449538032Speter RUS University of Stuttgart. 449638032Speter Minor lint fixes. 449738032Speter Return a temporary error instead of a permanent error if an LDAP map 449838032Speter search returns an error. This will allow sequenced maps which 449938032Speter use other LDAP servers to be checked. Fix from Booker Bense 450038032Speter of Stanford University. 450138032Speter When automatically converting from quoted printable to 8bit text do 450238032Speter not pad bare linefeeds with a space. Problem noted by Theo 450338032Speter Nolte of the University of Technology Aachen, Germany. 450438032Speter Portability: 450538032Speter Non-standard C compilers may have had a problem compiling 450638032Speter conf.c due to a standard C external declaration of 450738032Speter setproctitle(). Problem noted by Ted Roberts of 450838032Speter Electronic Data Systems. 450938032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 451038032Speter Jagielski of jaguNET Access Services. 451138032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 451238032Speter Digital UNIX: Digital UNIX (and possibly others) moves 451338032Speter loader environment variables into the loader memory 451438032Speter area. If one of these environment variables (such as 451538032Speter LD_LIBRARY_PATH) was the last environment variable, 451638032Speter an invalid memory address would be used by the process 451738032Speter title routine causing memory corruption. Problem 451838032Speter noted by Sam Hartman of Mesa Internet Systems. 451938032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 452038032Speter chownsafe() to always return 0 even if the OS does 452138032Speter not permit file giveaways. Problem noted by 452238032Speter Yasutaka Sumi of The University of Tokyo. 452364562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 452438032Speter Gerald Rinske of Siemens Business Services VAS. 452538032Speter Linux: Pad process title with NULLs. Problem noted by 452638032Speter Jon Lewis of Florida Digital Turnpike. 452738032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 452838032Speter incorrect value for the number of interfaces. 452938032Speter Problem noted by Chris Loelke of JetStream Internet 453038032Speter Services. 453138032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 453238032Speter Rinske of Siemens Business Services VAS. 453338032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 453438032Speter used on a Solaris machine. Problem noted by 453538032Speter Stephen Ma of Jtec Pty Limited. 453638032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 453738032Speter Services VAS. 453838032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 453938032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 454038032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 454138032Speter Ericsson. 454238032Speter 454364562Sgshapiro8.8.7/8.8.7 1997/08/03 454438032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 454538032Speter an exclusive lock already set -- i.e., almost all systems 454638032Speter except 4.4-BSD derived systems), the initial attempt at 454738032Speter rebuilding aliases file if the database didn't already 454838032Speter exist would fail. Patch from Raymund Will of LST Software 454938032Speter GmbH. 455038032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 455138032Speter Problem noted by Fredrik J�nsson of the Royal Institute 455238032Speter of Technology, Stockholm. 455338032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 455438032Speter some environments could give "multiple definitions" for these 455538032Speter routines during compilation. If using TCP Wrappers, assume 455638032Speter that these routines are included as though they were in the 455738032Speter C library. Patch from Robert La Ferla. 455838032Speter When a NEWDB database map was rebuilt at the same time it was being 455938032Speter used by a queue run, the maps could be left locked for the 456038032Speter duration of the queue run, causing other processes to hang. 456138032Speter Problem noted by Kendall Libby of Shore.NET. 456238032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 456338032Speter mail was passed on without any recipient header. This could 456438032Speter cause problems downstream. Problem noted by Xander Jansen 456538032Speter of SURFnet ExpertiseCentrum. 456638032Speter Give error when GDBM is used with sendmail. GDBM's locking and 456738032Speter linking of the .dir and .pag files interferes with sendmail's 456838032Speter locking and security checks. Problems noted by Fyodor 456938032Speter Yarochkin of the Kyrgyz Republic FreeNet. 457038032Speter Don't fsync qf files if SuperSafe option is not set. 457138032Speter Avoid extra calls to gethostbyname for addresses for which a 457238032Speter gethostbyaddr found no value. Also, ignore any returns 457338032Speter from gethostbyaddr that look like a dotted quad. 457438032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 457538032Speter "may be forged", since at the network level we pretty much 457638032Speter have to assume that the information is good. 457738032Speter In some cases, errors during an SMTP session could leave files 457838032Speter open or locked. 457938032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 458090792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 458138032Speter errors during testing. 458238032Speter Errors in file locking of NEWDB maps had the incorrect file name 458338032Speter printed in the error message. 458438032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 458538032Speter missing parameter were issued, the EHLO behaved like a HELO. 458638032Speter Load limiting never kicked in for incoming SMTP transactions if the 458743730Speter DeliveryMode=background and any recipient was an alias or 458838032Speter had a .forward file. From Nik Conwell of Boston University. 458938032Speter On some non-Posix systems, the decision of whether chown(2) permits 459038032Speter file giveaway was undefined. From Tetsu Ushijima of the 459138032Speter Tokyo Institute of Technology. 459238032Speter Fix race condition that could cause the body of a message to be 459338032Speter lost (so only the header was delivered). This only occurs 459438032Speter on systems that do not use flock(2), and only when a queue 459538032Speter runner runs during a critical section in another message 459638032Speter delivery. Based on a patch from Steve Schweinhart of 459738032Speter Results Computing. 459838032Speter If a qf file was found in a mail queue directory that had a problem 459938032Speter (wrong ownership, bad format, etc.) and the file name was 460038032Speter exactly MAXQFNAME bytes long, then instead of being tried 460138032Speter once, it would be tried on every queue run. Problem noted 460238032Speter by Bryan Costales of Mercury Mail. 460338032Speter If the system supports an st_gen field in the status structure, 460438032Speter include it when reporting that a file has changed after open. 460538032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 460638032Speter This out to be checked as well as reported, since it is 460738032Speter theoretically possible for an attacker to remove a file after 460838032Speter it is opened and replace it with another file that has the 460938032Speter same i-number, but some filesystems (notably AFS) return 461038032Speter garbage in this field, and hence always look like the file 461138032Speter has changed. As a practical matter this is not a security 461238032Speter problem, since the files can be neither hard nor soft links, 461338032Speter and on no filesystem (that I am aware of) is it possible to 461438032Speter have two files on the same filesystem with the same i-number 461538032Speter simultaneously. 461638032Speter Delete the root Makefile from the distribution -- it is only for 461738032Speter use internally, and does not work at customer sites. 461838032Speter Fix botch that caused the second MAIL FROM: command in a single 461938032Speter transaction to clear the entire transaction. Problem 462038032Speter noted by John Kennedy of Cal State University, Chico. 462138032Speter Work properly on machines that have _PATH_VARTMP defined without 462238032Speter a trailing slash. (And a pox on vendors that decide to 462338032Speter ignore the established conventions!) Problem noted by 462438032Speter Gregory Neil Shapiro of WPI. 462538032Speter Internal changes to make it easier to add another protocol family 462638032Speter (intended for IPv6). Patches are from John Kennedy of 462738032Speter CSU Chico. 462838032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 462938032Speter an extra space at the beginning of some lines. Problem 463038032Speter noted by Charles Karney of Princeton University; fix based 463138032Speter on a patch from Christophe Wolfhugel. 463238032Speter Portability: 463338032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 463438032Speter with the _Sendmail_ book, 2nd edition. Note that 463538032Speter the book is actually wrong: _PATH_SENDMAILCF should 463638032Speter be used instead. 463738032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 463838032Speter of Argonne National Laboratory. 463938032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 464038032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 464138032Speter SunOS: Include <memory.h> to fix warning from util.c. From 464238032Speter James Aldridge of EUnet Ltd. 464338032Speter Solaris: Change STDIR (location of status file) to /etc/mail 464438032Speter in Makefiles. 464538032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 464638032Speter Makefiles. Use NEWDB on Linux instead. 464738032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 464838032Speter exists but behaves differently than other OSes. 464938032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 465038032Speter around the problem. Problem noted by Tom Moore of 465138032Speter NCR Corp. 465238032Speter HP-UX 9.x: fix compile warnings for old select API. Problem 465338032Speter noted by Tom Smith of Digital Equipment Corp. 465438032Speter UnixWare 2.x: compile warnings on offsetof macro. Problem 465538032Speter noted by Tom Good of the Community Access Information 465638032Speter Resource Network 465738032Speter SCO 4.2: compile problems caused by a change in the type of 465838032Speter the "length" parameters passed to accept, getpeername, 465938032Speter getsockname, and getsockopt. Adds new compile flags 466038032Speter SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. Problem reported 466138032Speter by Tom Good of St. Vincent's North Richmond Community 466238032Speter Mental Health Center Residential Services. 466338032Speter AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. 466438032Speter Suggested by Brett Hogden of Rochester Gas & Electric 466538032Speter Corp. 466638032Speter Linux: avoid compile problem for versions of <setjmp.h> that 466738032Speter #define both setjmp and longjmp.

This makes it possible to create a root 470538032Speter owned file in an arbitrary directory by inserting the symlink 470638032Speter into a writable directory after the initial lstat(2) check 470738032Speter determined that the file did not exist. The only verified 470838032Speter example of a system having these odd semantics for O_EXCL 470938032Speter and symbolic links was HP-UX prior to version 9.07. Most 471038032Speter systems do not have the problem, since a exclusive create 471138032Speter of a file disallows symbolic links. Systems that have been 471238032Speter verified to NOT have the problem include AIX 3.x, *BSD, 471338032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 471438032Speter and Ultrix. This is a potential exposure on systems that 471538032Speter have this bug and which do not have a MAILER-DAEMON alias 471638032Speter pointing at a legitimate account, since this will cause old 471738032Speter mail to be dropped in /var/tmp/dead.letter. 471838032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 471938032Speter if maps or alias files are in world writable directories. 472038032Speter If your system has alias maps in writable directories, it 472138032Speter is potentially possible for an attacker to replace the .db 472238032Speter (or .dir and .pag) files by symbolic links pointing at 472338032Speter another database; this can be used either to expose 472438032Speter information (e.g., by pointing an alias file at /etc/spwd.db 472538032Speter and probing for accounts), or as a denial-of-service attack 472638032Speter (by trashing the password database). The fix disallows 472738032Speter symbolic links entirely when rebuilding alias files or on 472838032Speter maps that are in writable directories, and always warns on 472938032Speter writable directories; 8.9 will probably consider writable 473038032Speter directories to be fatal errors. This does not represent an 473138032Speter exposure on systems that have alias files in unwritable 473238032Speter system directories. 473338032Speter SECURITY: disallow .forward or :include: files that are links (hard 473438032Speter or soft) if the parent directory (or any directory in the 473538032Speter path) is writable by anyone other than the owner. This is 473638032Speter similar to the previous case for user files. This change 473738032Speter should not affect most systems, but is necessary to prevent 473838032Speter an attacker who can write the directory from pointing such 473938032Speter files at other files that are readable only by the owner. 474038032Speter SECURITY: Tighten safechown rules: many systems will say that they 474138032Speter have a safe (restricted to root) chown even on files that 474238032Speter are mounted from another system that allows owners to give 474338032Speter away files. The new rules are very strict, trusting file 474438032Speter ownership only in those few cases where the system has 474538032Speter been verified to be at least as paranoid as necessary. 474638032Speter However, it is possible to relax the rules to partially 474738032Speter trust the ownership if the directory path is not world or 474838032Speter group writable. This might allow someone who has a legitimate 474938032Speter :include: file (referenced directly from /etc/aliases) to 475038032Speter become another non-root user if the :include: file is in a 475138032Speter non-writable directory on an NFS-mounted filesystem where 475238032Speter the local system says that giveaway is denied but it is 475338032Speter actually permitted. I believe this to be a very small set 475438032Speter of cases. If in doubt, do not point :include: aliases at 475538032Speter NFS-mounted filesystems. 475638032Speter SECURITY: When setting a numeric group id using the RunAsUser option 475738032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 475838032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 475938032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 476038032Speter The user id was still set properly. Problem noted by Uli 476138032Speter Pralle of the Technical University of Berlin. 476238032Speter Save the initial gid set for use when checking for if the 476338032Speter PrivacyOptions=restrictmailq option is set. Problem reported 476438032Speter by Wolfgang Ley of DFN-CERT. 476538032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 476638032Speter failure on one message won't affect future messages to the 476738032Speter same host). 476838032Speter IP source route printing had an "off by one" error that would 476938032Speter affect any options that came after the route option. Patch 477038032Speter from Theo de Raadt. 477138032Speter The "Message is too large" error didn't successfully bounce the error 477238032Speter back to the sender. Problem reported by Stephen More of 477338032Speter PSI; patch from Gregory Neil Shapiro of WPI. 477438032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 477538032Speter of 5.1.3); it apparently gets used in multiple ways. 477638032Speter Suggested by John Myers of Portola Communications. 477738032Speter Fix possible extra null byte generated during collection if errors 477838032Speter occur at the beginning of the stream. Patch contributed by 477938032Speter Andrey A. Chernov and Gregory Neil Shapiro. 478038032Speter Code changes to avoid possible reentrant call of malloc/free within 478138032Speter a signal handler. Problem noted by John Beck of Sun 478238032Speter Microsystems. 478338032Speter Move map initialization to be earlier so that check_relay ruleset 478438032Speter will have the latest version of the map data. Problem noted 478538032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 478638032Speter If there are fatal errors during the collection phase (e.g., message 478738032Speter too large) don't send the bogus message. 478838032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 478938032Speter have errors and have owner- aliases. Problem noted by Michael 479038032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 479138032Speter Avoid null pointer dereference on illegal Boundary= parameters in 479238032Speter multipart/mixed Content-Type: header. Problem noted by 479338032Speter Richard Muirden of RMIT University. 479438032Speter Always print error messages during newaliases (-bi) even if the 479538032Speter ErrorMode is not set to "print". Fix from Gregory Neil 479638032Speter Shapiro. 479738032Speter Test mode could core dump if you did a /map lookup in an optional map 479838032Speter that could not be opened. Based on a fix from John Beck of 479938032Speter Sun Microsystems. 480038032Speter If DNS is misconfigured so that the last MX record tried points to 480138032Speter a host that does not have an A record, but other MX records 480238032Speter pointed to something reasonable, don't bounce the message 480338032Speter with a "host unknown" error. Note that this should really 480438032Speter be fixed in the zone file for the domain. Problem noted by 480538032Speter Joe Rhett of Navigist, Inc. 480638032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 480738032Speter the message as having been tried; otherwise the next queue 480838032Speter run will not realize that this is a second attempt and will 480938032Speter retry immediately. Problem noted by Bryan Costales of 481038032Speter Mercury Mail. 481138032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 481238032Speter will be run until the later setting of the clock is reached. 481338032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 481438032Speter Morgan Stanley. 481538032Speter If the load average rises above the cutoff threshold (above which 481638032Speter sendmail will not process the queue at all) during a queue 481738032Speter run, abort the queue run immediately. Problem noted by 481838032Speter Bryan Costales of Mercury Mail. 481938032Speter The variable queue processing algorithm (based on the message size, 482038032Speter number of recipients, message precedence, and job age) was 482138032Speter non-functional -- either the entire queue was processed or 482238032Speter none of the queue was processed. The updated algorithm 482338032Speter does no queue run if a single recipient zero size job will 482438032Speter not be run. 482538032Speter If there is a fatal ("panic") message that will cause sendmail to 482638032Speter die immediately, never hold the error message for future 482738032Speter printing. 482838032Speter Force ErrorMode=print in -bt mode so that all errors are printed 482938032Speter regardless of the setting of the ErrorMode option in the 483038032Speter configuration file. Patch from Gregory Neil Shapiro. 483138032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 483238032Speter routine available in one of the libraries. Use it in conf.h. 483338032Speter The -m (match only) flag now works on host class maps. 483438032Speter If class hash or btree maps are rebuilt, sendmail will now detect 483538032Speter this and reopen the map. Previously, they could give 483638032Speter erroneous results during a single message processing 483738032Speter (but would recover when the next message was received). 483838032Speter Don't delete zero length queue files when doing queue runs until the 483938032Speter files are at least ten minutes old. This avoids a potential 484038032Speter race condition: the creator creates the qf file, getting back 484138032Speter a file descriptor. The queue runner locks it and deletes it 484238032Speter because it is zero length. The creator then writes the 484338032Speter descriptor that is now for a disconnected file, and the 484438032Speter job goes away. Based on a suggestion by Bryan Costales. 484538032Speter When determining the "validated" host name ($_ macro), do a forward 484638032Speter (A) DNS lookup on the result of the PTR lookup and compare 484738032Speter results. If they differ or if the PTR lookup fails, tag the 484838032Speter address as "may be forged". 484938032Speter Log null connections (i.e., hosts that connect but do not do any 485038032Speter substantive activity on the connection before disconnecting; 485138032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 485238032Speter Always permit "writes" to /dev/null regardless of the link count. 485338032Speter This is safe because /dev/null is special cased, and no open 485438032Speter or write is ever actually attempted. Patch from Villy Kruse 485538032Speter of TwinCom. 485638032Speter If a message cannot be sent because of a 552 (exceeded storage 485738032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 485838032Speter was given, don't return the body in the bounce, since there 485938032Speter is a very good chance that the message will double-bounce. 486038032Speter Fix possible line truncation if a quoted-printable had an =00 escape 486138032Speter in the body. Problem noted by Charles Karney of the Princeton 486238032Speter Plasma Physics Laboratory. 486338032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 486438032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 486538032Speter Institute. 486638032Speter The MaxDaemonChildren option wasn't applying to queue runs as 486738032Speter documented. Note that this increases the potential denial 486838032Speter of service problems with this option: an attacker can 486938032Speter connect many times, and thereby lock out queue runs as well 487038032Speter as incoming connections. If you use this option, you should 487138032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 487238032Speter to avoid this attack. Failure to limit noted by Matthew 487338032Speter Dillon of BEST Internet Communications. 487438032Speter Always give a message in newaliases if alias files cannot be 487538032Speter opened instead of failing silently. Suggested by Gregory 487638032Speter Neil Shapiro. This change makes the code match the O'Reilly 487738032Speter book (2nd edition). 487838032Speter Some older versions of the resolver could return with h_errno == -1 487938032Speter if no name server could be reached, causing mail to bounce 488038032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 488138032Speter John Beck of SunSoft. 488238032Speter If a :include: file is owned by a user that does not have an entry 488338032Speter in the passwd file, sendmail could dereference a null pointer. 488438032Speter Problem noted by Satish Mynam of Sun Microsystems. 488538032Speter Take precautions to make sure that the SMTP protocol cannot get out 488638032Speter of sync if (for example) an alias file cannot be opened. 488738032Speter Fix a possible race condition that can cause a SIGALRM to come in 488838032Speter immediately after a SIGHUP, causing the new sendmail to die. 488938032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 489038032Speter from Villy Kruse of TwinCom. 489138032Speter Ignore improperly formatted SMTP reply codes. Previously these were 489238032Speter partially processed, which could cause confusing error 489338032Speter returns. 489438032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 489538032Speter on some architectures. 489638032Speter Portability: 489738032Speter A/UX: from Jim Jagielski of NASA/GSFC. 489838032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 489938032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 490038032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 490138032Speter defined. Problem reported by A Sun of the University 490238032Speter of Washington. 490338032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 490438032Speter the system rather than guessing at compile time. 490538032Speter Patch contributed by John Beck of Sun Microsystems. 490638032Speter Intel Paragon: from Wendy Lin of Purdue University. 490738032Speter GNU Hurd: from Miles Bader of the GNU project. 490838032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 490938032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 491038032Speter Unfortunately releasing them opens a race condition, 491138032Speter but there appears to be no fix for this. Patch from 491238032Speter Gregory Neil Shapiro. 491338032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 491438032Speter Solaris: a bug in strcasecmp caused characters with the 491538032Speter high order bit set to apparently randomly match 491638032Speter letters -- for example, $| (0233) matches "i" and "I". 491738032Speter Problem noted by John Gregson of the University of 491838032Speter Cambridge. 491938032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 492038032Speter Kari Hurtta. 492138032Speter IRIX 6.x: Create Makefiles for systems that claim to be 492238032Speter IRIX64 but are 6.2 or higher (so use the regular 492338032Speter IRIX Makefile). 492438032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 492538032Speter Problem noted by Eric Hagberg of Morgan Stanley. 492638032Speter CONFIG: Some canonification was still done for UUCP-like addresses 492738032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 492838032Speter Brian Candler. 492938032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 493038032Speter local names as local. Problem noted by Jeff Polk of BSDI; 493138032Speter fix provided by Gregory Neil Shapiro. 493238032Speter CONFIG: The "local:user" syntax entries in mailertables and other 493338032Speter "mailer:user" syntax locations returned an incorrect value 493438032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 493538032Speter CONFIG: Retain "+detail" information when forwarding mail to a 493638032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 493738032Speter Guenther of Gustavus Adolphus College. 493838032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 493938032Speter rules are the same as for aliasing. Based on a patch from 494038032Speter Gregory Neil Shapiro. 494138032Speter CONFIG: Break up parsing rules into several pieces; this should 494238032Speter have no functional change in this release, but makes it 494338032Speter possible to have better anti-spam rulesets in the future. 494438032Speter CONFIG: Disallow double dots in host names to avoid having the 494538032Speter HostStatusDirectory store status under the wrong name. 494638032Speter In some cases this can be used as a denial-of-service attack. 494738032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 494838032Speter Gregory Neil Shapiro. 494938032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 495038032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 495138032Speter don't include From_, and convert to 8-bit). Suggestions 495238032Speter from Kimmo Suominen and Roderick Schertler. 495364562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 495438032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 495538032Speter was specified, even when it wasn't. 495638032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 495738032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 495838032Speter "slip in" a symbolic link between the lstat(2) call and the 495938032Speter exclusive open. This is only a problem on System V derived 496038032Speter systems that allow an exclusive create on files that are 496138032Speter symbolic links pointing nowhere. 496238032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 496338032Speter not reset back to root, which on some systems would cause 496438032Speter later mailboxes to fail. Also, any partial message would 496538032Speter not be truncated, which could result in repeated deliveries. 496638032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 496738032Speter developers). 496838032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 496938032Speter change to the sendmail map code was made in 8.8.3. Problem 497038032Speter noted by Gregory Neil Shapiro. 497138032Speter MAKEMAP: Give warnings on file problems such as map files that are 497290792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 497338032Speter often run as root and hence has the potential for the same 497438032Speter sorts of problems as alias rebuilds. 497538032Speter MAKEMAP: Change compilation so that it will link properly on 497638032Speter NEXTSTEP. 497738032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 497838032Speter Accept an optional list of arguments following the server 497938032Speter name for the ETRN arguments to use (instead of $=w).

This 498338032Speter Perl script converts GECOS information in the /etc/passwd 498438032Speter file into aliases, allowing for faster access to full name 498538032Speter lookups; it is also clever about adding aliases (to root) 498638032Speter for system accounts. 498738032Speter NEW FILES: 498838032Speter src/safefile.c 498938032Speter cf/ostype/gnuhurd.m4 499038032Speter cf/ostype/irix6.m4 499138032Speter contrib/passwd-to-alias.pl 499238032Speter src/Makefiles/Makefile.IRIX64.6.1 499338032Speter src/Makefiles/Makefile.IRIX64.6.x 499438032Speter RENAMED FILES: 499538032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 499638032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 499738032Speter 499864562Sgshapiro8.8.5/8.8.5 1997/01/21 499938032Speter SECURITY: Clear out group list during startup. Without this, sendmail 500038032Speter will continue to run with the group permissions of the caller, 500138032Speter even if RunAsUser is specified. 500238032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 500338032Speter to any known attack, but it's best to be conservative. 500438032Speter Suggested by Peter Wemm of DIALix. 500538032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 500638032Speter security implications. Patch from Alex Garthwaite of the 500738032Speter University of Pennsylvania. 500838032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 500938032Speter would truncate the address after "Full". Although the -f 501038032Speter syntax is incorrect (since it is in the envelope, it 501138032Speter shouldn't have comments and full names), the failure mode 501238032Speter was unnecessarily awful. 501338032Speter Fix a possible null pointer dereference when converting 8-bit data 501438032Speter to a 7-bit format. Problem noted by Jim Hutchins of 501538032Speter Sandia National Labs and David James of British Telecom. 501638032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 501738032Speter runs. Although this really shouldn't be used (F=9 is for 501838032Speter final delivery only, and using it on an SMTP mailer makes 501938032Speter it possible for a message to be converted from 8->7->8->7 502038032Speter bits several times), it shouldn't have failed with a syserr. 502138032Speter Problem noted by Eric Hagberg of Morgan Stanley. 502238032Speter _Really_ fix the multiple :maildrop code in the user database 502338032Speter module. Patch from Roy Mongiovi of Georgia Tech. 502438032Speter Let F lines in the configuration file actually read root-only 502538032Speter files if the configuration file is safe. Based on a 502638032Speter patch from Keith Reynolds of SCO. 502738032Speter ETRN followed by QUIT would hold the connection open until the queue 502838032Speter run completed. Problem noted by Truck Lewis of TDK 502938032Speter Semiconductor Corp. 503038032Speter It turns out that despite the documentation, the TCP wrappers library 503138032Speter does _not_ log rejected connections. Do the logging ourselves. 503238032Speter Problem noted by Fletcher Mattox of the University of Texas 503338032Speter at Austin. 503438032Speter If sendmail finds a qf file in its queue directory that is an unknown 503538032Speter version (e.g., when backing out to an old version), the 503638032Speter error is reported on every queue run. Change it to only 503738032Speter give the error once (and rename the qf => Qf). Patch from 503838032Speter William A. Gianopoulos of Raytheon Company. 503938032Speter Start a new session when doing background delivery; currently it 504038032Speter ignored signals but didn't start a new signal, that caused 504138032Speter some problems if a background process tried to send mail 504238032Speter under certain circumstances. Problem noted by Eric Hagberg 504338032Speter of Morgan Stanley; fix from Kari Hurtta. 504438032Speter Simplify test for skipping a queue run to just check if the current 504538032Speter load average is >= the queueing load average. Previously 504638032Speter the check factored in some other parameters that caused it 504738032Speter to essentially never skip the queue run. Patch from Bryan 504838032Speter Costales. 504938032Speter If the SMTP server is running in "nullserver" mode (that is, it is 505038032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 505138032Speter (25) commands; this helps prevent a bad guy from putting 505238032Speter you into a tight loop as a denial-of-service attack. Based 505338032Speter on an e-mail conversation with Brad Knowles of AOL. 505438032Speter Slow down when too many "light weight" commands have been issued; 505538032Speter this helps prevent a class of denial-of-service attacks. 505638032Speter The current values and defaults are: 505738032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 505838032Speter MAXHELOCOMMANDS 3 HELO, EHLO 505938032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 506038032Speter MAXETRNCOMMANDS 8 ETRN 506138032Speter These will probably be configurable in a future release. 506238032Speter On systems that have uid_t typedefed to be an unsigned short, programs 506338032Speter that had the F=S flag and no U= equate would be invoked with 506438032Speter the real uid set to 65535 rather than being left unchanged. 506538032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 506638032Speter by Steve Hubert of the University of Washington, Seattle. 506738032Speter Mail that was Quoted-Printable encoded and had a soft line break on 506838032Speter the last line (i.e., an incomplete continuation) had the last 506938032Speter line dropped. Since this appears to be illegal it isn't 507038032Speter clear what to do with it, but flushing the last line seems 507138032Speter to be a better "fail soft" approach. Based on a patch from 507238032Speter Eric Hagberg. 507338032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 507438032Speter bogus HELO command still causes the "Polite people say HELO 507538032Speter first" error message. Problem pointed out by Chris Thomas 507638032Speter of UCLA; patch from John Beck of SunSoft. 507738032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 507871345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 507971345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 508071345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 508138032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 508238032Speter in a DATA transaction to be sticky; these can occur because 508338032Speter a message is too large, and smaller messages should still go 508438032Speter through. Problem noted by Matt Dillon of Best Internet 508538032Speter Communications. 508638032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 508738032Speter had been successfully delivered to the envelope sender. 508838032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 508938032Speter Gregory Neil Shapiro of WPI. 509038032Speter Give better diagnostics on long alias lines. Based on code contributed 509138032Speter by Patrick Gosling of the University of Cambridge. 509238032Speter Increase the number of virtual interfaces that will be probed for 509338032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 509438032Speter PORTABILITY: 509538032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 509638032Speter Toshiaki Nomura of Fujitsu Limited. 509738032Speter SunOS with LDAP support: compile problems with struct timeval. 509838032Speter Patch from Nick Cuccia of TCSI Corporation. 509938032Speter SCO: from Keith Reynolds of SCO. 510038032Speter Solaris: kstat load average computation wasn't being used. 510138032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 510238032Speter (Moscow). 510338032Speter OpenBSD: from Jason Downs of teeny.org. 510438032Speter Altos System V: from Tim Rice. 510538032Speter Solaris 2.5: from Alan Perry of SunSoft. 510638032Speter Solaris 2.6: from John Beck of SunSoft. 510738032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 510838032Speter of Pratt & Whitney <miorelli@pweh.com>. 510938032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 511038032Speter _just_right_ yet. Tweak it again. I'll omit the names 511138032Speter of the "contributors" (quantity two) in this one case. 511238032Speter As of now, NO MORE DISCUSSION about the syntax of the 511338032Speter Received: line. 511438032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 511538032Speter it never inserts that class into the output file. Fix it 511638032Speter so it will honor EXPOSED_USER but will _not_ include root 511738032Speter automatically in this class. Problem noted by Ronan KERYELL 511838032Speter of Centre de Recherche en Informatique de l'�cole Nationale 511938032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 512038032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 512138032Speter such as LUSER_RELAY. This change permits the following 512238032Speter syntaxes: ``local:'' will send to the same user on the 512338032Speter local machine (e.g., in a mailertable entry for "host", 512438032Speter ``local:'' will cause an address addressed to user@host to 512538032Speter go to user on the local machone). ``local:user'' will send 512638032Speter to the named user on the local machine. ``local:user@host'' 512738032Speter is equivalent to ``local:user'' (the host is ignored). In 512838032Speter all cases, the original user@host is passed in $@ (i.e., the 512938032Speter detail information). Inspired by a report from Michael Fuhr. 513038032Speter CONFIG: Strip quotes from the first word of an "error:" host 513138032Speter indication. This lets you set (for example) the LUSER_RELAY 513238032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 513338032Speter of the \" so that the resulting string is properly quoted. 513438032Speter Problem noted by Gregory Neil Shapiro of WPI. 513538032Speter OP.ME: documentation was inconsistent about whether sendmail did a 513638032Speter NOOP or a RSET to probe the connection (it does a RSET). 513738032Speter Inconsistency noted by Deeran Peethamparam. 513838032Speter OP.ME: insert additional blank pages so it will print properly on 513938032Speter a duplex printer. From Matthew Black of Cal State University, 514038032Speter Long Beach. 514138032Speter 514264562Sgshapiro8.8.4/8.8.4 1996/12/02 514338032Speter SECURITY: under some circumstances, an attacker could get additional 514438032Speter permissions by hard linking to files that were group 514538032Speter writable by the attacker. The solution is to disallow any 514638032Speter files that have hard links -- this will affect .forward, 514738032Speter :include:, and output files. Problem noted by Terry 514838032Speter Kyriacopoulos of Interlog Internet Services. As a 514938032Speter workaround, set UnsafeGroupWrites -- always a good idea. 515038032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 515138032Speter is, it is possible to do a denial-of-service attack on 515238032Speter MX hosts that rely on the use of the null MX list. There 515338032Speter is no danger if you have this option turned off (the default). 515438032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 515538032Speter unsafe. I know of no specific attack against this, although 515638032Speter a denial-of-service attack is probably possible, but in theory 515738032Speter you should not be able to safely tweak anything that affects 515838032Speter the permissions that are used when mail is delivered. 515938032Speter Purgestat could go into an infinite loop if one of the host status 516038032Speter directories somehow became empty. Problem noted by Roy 516138032Speter Mongiovi of Georgia Tech. 516238032Speter Processes got "lost" when counting children due to a race condition. 516338032Speter This caused "proc_list_probe: lost pid" messages to be logged. 516438032Speter Problem noted by several people. 516538032Speter On systems with System V SIGCLD child signal semantics (notably AIX 516638032Speter and HP-UX), mail transactions would print the message "451 516738032Speter SMTP-MAIL: lost child: No child processes". Problem noted 516838032Speter by several people. 516938032Speter Miscellaneous compiler warnings on picky compilers (or when setting 517038032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 517138032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 517238032Speter not be persistent between runs, since they are based on the 517338032Speter message rather than the host. Problem noted by Matt Dillon 517438032Speter of Best Internet Communications. 517538032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 517638032Speter of NCR (a.k.a., AT&T Global Information Solutions). 517738032Speter Avoid the possibility of having a child daemon run to completion 517838032Speter (including closing the SMTP socket) before the parent has 517938032Speter had a chance to close the socket; this can cause the parent 518038032Speter to hang for a long time waiting for the socket to drain. 518138032Speter Patch from Don Lewis of TDK Semiconductor. 518238032Speter If the fork() failed in a queue run, the queue runners would not be 518338032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 518438032Speter Some error conditions in ETRN could cause output without an SMTP 518538032Speter status code. Problem noted by Don Lewis. 518638032Speter Multiple :maildrop addresses in the user database didn't work properly. 518738032Speter Patch from Roy Mongiovi of Georgia Tech. 518838032Speter Add ".db" automatically onto any user database spec that does not 518938032Speter already have it; this is for consistency with makemap, the 519038032Speter K line, and the documentation. Inconsistency pointed out 519138032Speter by Roy Mongiovi. 519238032Speter Allow sendmail to be properly called in nohup mode. Patch from 519338032Speter Kyle Jones of UUNET. 519438032Speter Change ETRN to ignore but still update host status files; previously 519538032Speter it would ignore them and not save the updated status, which 519638032Speter caused stale information to be maintained. Based on a patch 519738032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 519838032Speter ETRN ignore the MinQueueAge option. 519938032Speter Patch long term host status to recover more gracefully from an empty 520038032Speter host status file condition. Patch from NAKAMURA Motonori 520138032Speter of Kyoto University. 520238032Speter Several patches to signal handling code to fix potential race 520338032Speter conditions from Don Lewis. 520438032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 520538032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 520638032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 520738032Speter compile flag; use NETINET instead. Solution based on a 520838032Speter patch from Bryan Costales. 520938032Speter PORTABILITY FIXES: 521038032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 521138032Speter /etc/security/passwd file when called as root. This 521238032Speter is very slow on some systems. To speed it up, use the 521338032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 521438032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 521538032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 521638032Speter Glicker of Burrelle's Information Service. 521738032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 521838032Speter from Makoto MATSUSHITA of Osaka University. 521938032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 522038032Speter Leeds University and SASABE Tetsuro of the University 522138032Speter of Tokyo. 522238032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 522338032Speter Services, Inc. 522438032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 522538032Speter I believe this to have only been a problem if you 522638032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 522738032Speter to stick with /etc/sendmail.cf as your One True Path. 522838032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 522938032Speter Martin Laubach of the Technischen Universit�t Wien. 523038032Speter CONFIG: change default Received: line to be multiple lines rather 523138032Speter than one long one. By popular demand. 523238032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 523338032Speter from Jerome Berkman of U.C. Berkeley. 523438032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 523538032Speter to take a very long time. Problem noted by Yoshiro YONEYA 523638032Speter of NTT Software Corporation. 523738032Speter CONTRIB: add etrn.pl, contributed by John Beck. 523838032Speter NEW FILES: 523938032Speter contrib/etrn.pl 524038032Speter 524164562Sgshapiro8.8.3/8.8.3 1996/11/17 524238032Speter SECURITY: it was possible to get a root shell by lying to sendmail 524338032Speter about argv[0] and then sending it a signal. Problem noted 524438032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 524538032Speter best-of-security list. 524638032Speter Log sendmail binary version number in "Warning: .cf version level 524738032Speter (%d) exceeds program functionality (%d) message" -- this 524838032Speter should make it clearer to people that they are running 524938032Speter the wrong binary. 525038032Speter Fix a problem that occurs when you open an SMTP connection and then 525138032Speter do one or more ETRN commands followed by a MAIL command; at 525238032Speter the end of the DATA phase sendmail would incorrectly report 525338032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 525438032Speter noted by Eric Bishop of Virginia Tech. 525538032Speter When doing text-based host canonification (typically /etc/hosts 525638032Speter lookup), a null host name would match any /etc/hosts entry 525738032Speter with space at the end of the line. Problem noted by Steve 525838032Speter Hubert of the University of Washington, Seattle. 525938032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 526038032Speter Problem reported by Tom Smith of Digital Equipment Corp. 526138032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 526238032Speter size PACKETSZ (512) is not sufficient for some nameserver 526338032Speter answers containing very many resource records. The resolver 526438032Speter may also switch to TCP and retry if it detects UDP packet 526538032Speter overflow. Also, allow for the fact that the resolver 526638032Speter routines res_query and res_search return the size of the 526738032Speter *un*truncated answer in case the supplied answer buffer it 526838032Speter not big enough to accommodate the entire answer. Patch from 526938032Speter Eric Wassenaar. 527038032Speter Improvements to MaxDaemonChildren code. If you think you have too 527138032Speter many children, probe the ones you have to verify that they 527238032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 527338032Speter Also, do this probe before growing the vector of children 527438032Speter pids; this previously caused the vector to grow indefinitely 527538032Speter due to a race condition. Problem reported by Kyle Jones of 527638032Speter UUNET. 527738032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 527838032Speter O_EXLOCK to zero; this fools the map compilation code into 527938032Speter thinking that it can avoid race conditions by locking on open. 528038032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 528138032Speter Leif Erlingsson of Data Lege. 528238032Speter Always call res_init() on startup (if compiled in, of course) to 528338032Speter allow the sendmail.cf file to tweak resolver flags; without 528438032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 528538032Speter Andrew Sun of Merrill Lynch. 528638032Speter Improvements to host status printing code. Suggested by Steve Hubert 528738032Speter of the University of Washington, Seattle. 528838032Speter Change MinQueueAge option processing to do the check for the job age 528938032Speter when reading the queue file, rather than at the end; this 529038032Speter avoids parsing the addresses, which can do DNS lookups. 529138032Speter Problem noted by John Beck of InReference, Inc. 529238032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 529338032Speter properly escaped. Problem noted by Peter Nilsson of the 529438032Speter University of Linkoping. 529538032Speter In some cases, sendmail would retain root permissions during queue 529638032Speter runs even if RunAsUser was set. Problem noted by Mark 529738032Speter Thomas of Mark G. Thomas Consulting. 529838032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 529938032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 530038032Speter the envelope, and the receiving SMTP server speaks DSN, then 530138032Speter the DSN would be both generated locally and propagated to the 530238032Speter other end. 530338032Speter The U= mailer field didn't correctly extract the group id if the 530438032Speter user id was numeric. Problem noted by Kenneth Herron of 530538032Speter MCI Telecommunications Communications. 530638032Speter If a message exceeded the fixed maximum size on input, the body of 530738032Speter the message was included in the bounce. Note that this did 530838032Speter not occur if it exceeded the maximum _output_ size. Problem 530938032Speter reported by Kyle Jones of UUNET. 531038032Speter PORTABILITY FIXES: 531138032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 531238032Speter AIX4 defines to use seteuid(2) instead, which 531338032Speter works on 4.1 as well as 4.2. Problem noted by 531438032Speter H�kan Lindholm of interAF, Sweden. 531538032Speter AIX4: use tzname[] vector to determine time zone name. 531638032Speter Patch from NAKAMURA Motonori of Kyoto University. 531738032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 531838032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 531938032Speter Solaris: kstat(3k) support for retrieving the load average. 532038032Speter This adds the LA_KSTAT definition for LA_TYPE. 532138032Speter The outline of the implementation was contributed 532238032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 532338032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 532438032Speter declaration of struct rusage at the top of conf.h; 532538032Speter change it to only be included if you are using gcc, 532638032Speter which is apparently the only compiler that requires 532738032Speter it in the first place. Problem noted by Jeff 532838032Speter Earickson of Colby College. 532938032Speter IRIX: don't default to using gcc. IRIX is a civilized 533038032Speter operating system that comes with a decent compiler 533138032Speter by default. Problem noted by Barry Bouwsma and 533238032Speter Kari Hurtta. 533338032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 533438032Speter consistency with other local mailers. Inconsistency 533538032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 533638032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 533738032Speter overhead) as part of the bestmx_is_local feature, the 533838032Speter domain part was dropped from the name. Patch from Steve 533938032Speter Hubert of the University of Washington, Seattle. 534038032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 534138032Speter end up being translated to the null host name, which would 534238032Speter return any entry in /etc/hosts that had a space at the end 534338032Speter of the line. Problem noted by Steve Hubert of the 534438032Speter University of Washington, Seattle. 534538032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 534638032Speter Polytechnic Institute. 534738032Speter MAKEMAP: tweak hash and btree parameters for better performance. 534838032Speter Patch from Matt Dillon of Best Internet Communications. 534938032Speter NEW FILES: 535038032Speter src/Makefiles/Makefile.Linux.ppc 535138032Speter cf/ostype/aix4.m4 535238032Speter cf/ostype/mklinux.m4 535338032Speter 535464562Sgshapiro8.8.2/8.8.2 1996/10/18 535538032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 535638032Speter changed the code but didn't fix the problem. 535738032Speter PORTABILITY FIXES: 535838032Speter Solaris: Don't use the system getusershell(3); it can 535938032Speter apparently corrupt the heap in some circumstances. 536038032Speter Problem found by Ken Pizzini of Spry, Inc. 536138032Speter OP.ME: document several mailer flags that were accidentally omitted 536238032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 536338032Speter CONFIG: no changes. 536438032Speter 536564562Sgshapiro8.8.1/8.8.1 1996/10/17 536638032Speter SECURITY: unset all environment variables that the resolver will 536738032Speter examine during queue runs and daemon mode. Problem noted 536838032Speter by Dan Bernstein of the University of Illinois at Chicago. 536938032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 537038032Speter message could overflow a buffer if it was converted back 537138032Speter to 8 bits. This caused core dumps and has the potential 537238032Speter for a remote attack. Problem first noted by Gregory Shapiro 537338032Speter of WPI. 537438032Speter Avoid duplicate deliveries of error messages on systems that don't 537538032Speter have flock(2) support. Patch from Motonori Nakamura of 537638032Speter Kyoto University. 537738032Speter Ignore null FallBackMX (V) options. If this option is null (as 537838032Speter opposed to undefined) it can cause "null signature" syserrs 537938032Speter on illegal host names. 538038032Speter If a Base64 encoded text/plain message has no trailing newline in 538138032Speter the encoded text, conversion back to 8 bits will drop the 538238032Speter final line. Problem noted by Pierre David. 538338032Speter If running with a RunAsUser, sendmail would give bogus "cannot 538438032Speter setuid" (or seteuid, or setreuid) messages on some systems. 538538032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 538638032Speter Always print error messages in -bv mode -- previously, -bv would 538738032Speter be absolutely silent on errors if the error mode was sent 538838032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 538938032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 539038032Speter term host status. This is necessary because it is common 539138032Speter to do this when you know a host has just come back up. 539238032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 539338032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 539438032Speter University of Leicester. 539538032Speter If a service (such as NIS) is specified as the last entry in the 539638032Speter service switch, but that service is not compiled in, sendmail 539738032Speter would return a temporary failure when an entry was not found 539838032Speter in the map. This caused the message to be queued instead of 539938032Speter bouncing immediately. Problem noted by Harry Edmon of the 540038032Speter University of Washington. 540138032Speter PORTABILITY FIXES: 540238032Speter Solaris 2.3 had compilation problems in conf.c. Several 540338032Speter people pointed this out. 540438032Speter NetBSD from Charles Hannum of MIT. 540538032Speter AIX4 improvements based on info from Steve Bauer of South 540638032Speter Dakota School of Mines & Technology. 540738032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 540838032Speter Patch from Gil Kloepfer Jr. 540938032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 541038032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 541138032Speter were also in $=w. Problem noted by Zoltan Basti of 541238032Speter Softec. 541338032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 541438032Speter on a patch from Eric Hagberg of Morgan Stanley. 541538032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 541638032Speter of Stanford via Robert La Ferla. 541738032Speter 541864562Sgshapiro8.8.0/8.8.0 1996/09/26 541938032Speter Under some circumstances, Bcc: headers would not be properly 542038032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 542138032Speter Log a warning if the sendmail daemon is invoked without a full 542238032Speter pathname, which prevents "kill -1" from working. I was 542338032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 542438032Speter Fix small buffer overflow. Since the data in this buffer was not 542538032Speter read externally, there was no security problem (and in fact 542638032Speter probably wouldn't really overflow on most compilers). Pointed 542738032Speter out by KIZU takashi of Osaka University. 542838032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 542938032Speter if a FallbackMXHost was specified in the configuration file 543038032Speter -- all mail would be sent to the fallback even if the original 543138032Speter host was accessible. Pointed out by Munenari Hirayama of 543238032Speter NSC (Japan). 543338032Speter A message that didn't terminate with a newline would (sometimes) not 543438032Speter have the trailing "." added properly in the SMTP dialogue, 543538032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 543638032Speter The DaemonPortOptions suboption to bind to a particular address was 543738032Speter incorrect and nonfunctional due to a misunderstanding of the 543838032Speter semantics of binding on a passive socket. Patch from 543938032Speter NIIBE Yutaka of Mitsubishi Research Institute. 544038032Speter Increase the number of MX hosts for a single name to 100 to better 544138032Speter handle the truly huge service providers such as AOL, which 544238032Speter has 13 at the moment (and climbing). In order to avoid 544338032Speter trashing memory, the buffer for all names has only been 544438032Speter slightly increased in size, to 12.8K from 10.2K -- this means 544538032Speter that if a single name had 100 MX records, the average size 544638032Speter of those records could not exceed 128 bytes. Requested by 544738032Speter Brad Knowles of America On Line. 544838032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 544938032Speter Urged by Dan Bernstein of U.C. Berkeley. 545038032Speter Print q_statdate and q_specificity in address structure debugging 545138032Speter printout. 545238032Speter Expand MCI structure flag bits for debugging output. 545338032Speter Support IPv6-style domain literals, which can have colons between 545438032Speter square braces. 545538032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 545638032Speter this is an attempt to track down a bug that one person seems 545738032Speter to be having (it may be a Solaris bug!). 545838032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 545938032Speter this caused the NOTIFY info to sometimes be lost. Problem 546038032Speter pointed out by Claus Assmann of the 546138032Speter Christian-Albrechts-University of Kiel. 546238032Speter The statistics gathered in the sendmail.st file were too high; in 546338032Speter some cases failures (e.g., user unknown or temporary failure) 546438032Speter would count as a delivery as far as the statistics were 546538032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 546638032Speter Systems that don't have flock() would not send split envelopes in 546738032Speter the initial run. Problem pointed out by Leonard Zubkoff of 546838032Speter Dandelion Digital. 546938032Speter Move buffer overflow checking -- these primarily involve distrusting 547038032Speter results that may come from NIS and DNS. 547138032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 547238032Speter include <paths.h> and hence had the wrong pathnames for a few 547338032Speter things like /var/tmp. Reported by Matthew Green. 547438032Speter Conditions were reversed for the Priority: header, resulting in all 547538032Speter values being interpreted as non-urgent except for non-urgent, 547638032Speter which was interpreted as normal. Patch from Bryan Costales. 547738032Speter The -o (optional) flag was being ignored on hash and btree maps 547838032Speter since 8.7.2. Fix from Bryan Costales. 547938032Speter Content-Types listed in class "q" will always be encoded as 548038032Speter Quoted-Printable (or more accurately, will never be encoded 548138032Speter as base64). The class can have primary types (e.g., "text") 548238032Speter or full types (e.g., "text/plain"). Based on a suggestion by 548338032Speter Marius Olafsson of the University of Iceland. 548438032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 548538032Speter dialogue) so it can be passed to programs in mailers. 548638032Speter Define ${bodytype} to be the body type (from the -B flag or the 548738032Speter BODY= ESMTP parameter) so it can be passed to programs in 548838032Speter mailers. 548938032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 549038032Speter flag is set in the mailer descriptor. Suggested by John 549138032Speter Myers of CMU. 549238032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 549338032Speter The command takes a host name; data for that host is 549438032Speter immediately (and asynchronously) flushed. Because this shares 549538032Speter the -qR implementation, other hosts may be attempted, but 549638032Speter there should be no security implications. Implementation 549738032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 549838032Speter Add three new command line flags to pass in DSN parameters: -V envid 549938032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 550038032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 550138032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 550238032Speter that the -N flag applies to all recipients; there is no way 550338032Speter to specify per-address notifications on the command line, 550438032Speter nor is there an equivalent for the ORCPT= per-address 550538032Speter parameter. 550638032Speter Restore LogLevel option to be safe (it can only be increased); 550738032Speter apparently I went into paranoid mode between 8.6 and 8.7 550838032Speter and made it unsafe. Pointed out by Dabe Murphy of the 550938032Speter University of Maryland. 551038032Speter New logging on log level 15: all SMTP traffic. Patches from 551138032Speter Andrew Gross of San Diego Supercomputer Center. 551238032Speter NetInfo property value searching code wasn't stopping when it found 551338032Speter a match. This was causing the wrong values to be found (and 551438032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 551538032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 551638032Speter out by Bill Wisner of Electronics for Imaging that you can't 551738032Speter use the bracket address form for the MAIL_HUB macro, since 551838032Speter that causes the brackets to remain in the envelope recipient 551938032Speter address used for delivery. The simple fix (stripping off the 552038032Speter brackets in the config file) breaks the use of IP literal 552138032Speter addresses. This flag will solve that problem. 552238032Speter Add MustQuoteChars option. This is a list of characters that must 552338032Speter be quoted if they are found in the phrase part of an address 552438032Speter (that is, the full name part). The characters @,;:\()[] are 552538032Speter always in this list and cannot be removed. The default is 552638032Speter this list plus . and ' to match RFC 822. 552738032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 552838032Speter that do not include a host name for back compatibility with 552938032Speter some stupid SMTP clients. Setting this violates RFC 1123 553038032Speter section 5.2.5. 553138032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 553238032Speter rejecting connections if it has more than this many 553338032Speter outstanding children accepting mail. Note that you may 553438032Speter see more processes than this because of outgoing mail; this 553538032Speter is for incoming connections only. 553638032Speter Add ConnectionRateThrottle option. If set to a positive value, the 553738032Speter number of incoming SMTP connections that will be permitted 553838032Speter in a single second is limited to this number. Connections are 553938032Speter not refused during this time, just deferred. The intent is to 554038032Speter flatten out demand so that load average limiting can kick in. 554138032Speter It is less radical than MaxDaemonChildren, which will stop 554238032Speter accepting connections even if all the connections are idle 554338032Speter (e.g., due to connection caching). 554438032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 554538032Speter specifies how long cached information about the state of a 554638032Speter host will be kept before they are considered stale and the 554738032Speter host is retried. If you are using persistent host status 554838032Speter (i.e., the HostStatusDirectory option is set) this will apply 554938032Speter between runs; otherwise, it applies only within a single queue 555038032Speter run and hence is useful only for hosts that have large queues 555138032Speter that take a very long time to run. 555238032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 555338032Speter into being a single line even if they had newlines in them 555438032Speter when read. This is to get around a botch in Lotus Notes. 555538032Speter Text class maps were totally broken -- if you ever retrieved the last 555638032Speter item in a table it would be truncated. Problem noted by 555738032Speter Gregory Neil Shapiro of WPI. 555838032Speter Extend the lines printed by the mailq command (== the -bp flag) when 555938032Speter -v is given to 120 characters; this allows more information 556038032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 556138032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 556238032Speter this was treated as end-of-input. Problem noted by Bryan 556338032Speter Costales. 556438032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 556538032Speter to the queue file. Fix from John Hughes of Atlantic 556638032Speter Technologies, Inc. 556738032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 556838032Speter if this happens in a queue run it can cause nasty delays. 556938032Speter Problem noted by Mark Horton of AT&T. 557038032Speter If userdb entries pointed to userdb entries, and there were multiple 557138032Speter values for a given key, the database cursor would get 557238032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 557338032Speter of Georgia Tech. Fixed by reading all the values and creating 557438032Speter a comma-separated list; thus, the -v output will be somewhat 557538032Speter different for this case. 557638032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 557738032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 557838032Speter of Stanford University. 557938032Speter When envelopes were split due to aliases with owner- aliases, and 558038032Speter there was some error on one of the lists, more than one of 558138032Speter the owners would get the message. Problem pointed out by 558238032Speter Roy Mongiovi of Georgia Tech. 558338032Speter Detect excessive recursion in macro expansions, e.g., $X defined 558438032Speter in terms of $Y which is defined in terms of $X. Problem 558538032Speter noted by Bryan Costales; patch from Eric Wassenaar. 558638032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 558738032Speter some cases get trashed causing bogus From_ lines. Fix from 558838032Speter Kyle Jones of UUNET. 558938032Speter When doing load average initialization, if the nlist call for avenrun 559038032Speter failed, the second and subsequent lookups wouldn't notice 559138032Speter that fact causing bogus load averages to be returned. Noted 559238032Speter by Casper Dik of Sun Holland. 559338032Speter Fix problem with incompatibility with some versions of inet_aton that 559438032Speter have changed the return value to unsigned, so a check for an 559538032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 559638032Speter This could cause mail to addresses such as [foo.com] to bounce 559738032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 559838032Speter Pasteur Institute. 559938032Speter DSNs were inconsistent if a failure occurred during the DATA phase 560038032Speter rather than the RCPT phase: the Action: would be correct, but 560138032Speter the detailed status information would be wrong. Problem noted 560238032Speter by Bob Snyder of General Electric Company. 560338032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 560438032Speter that this is the initial MUA->MTA submission. The flag current 560538032Speter does nothing, but in future releases (when MUAs start using 560638032Speter these flags) it will probably turn on things like DNS 560738032Speter canonification. 560838032Speter Default end-of-line string (E= specification on mailer [M] lines) 560938032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 561038032Speter mailers. 561138032Speter Change the internal definition for the *file* and *include* mailers 561238032Speter to have $u in the argument vectors so that they aren't 561338032Speter misinterpreted as SMTP mailers and thus use \r\n line 561438032Speter termination. This will affect anyone who has redefined 561538032Speter either of these in their configuration file. 561638032Speter Don't assume that IDENT servers close the connection after a query; 561738032Speter responses can be newline terminated. From Terry Kennedy of 561838032Speter St. Peter's College. 561938032Speter Avoid core dumps on erroneous configuration files that have 562038032Speter $#mailer with nothing following. From Bryan Costales. 562138032Speter Avoid null pointer dereference with high debug values in unlockqueue. 562238032Speter Fix from Randy Martin of Clemson University. 562338032Speter Fix possible buffer overrun when expanding very large macros. Fix 562438032Speter from Kyle Jones of UUNET. 562538032Speter After 25 EXPN or VRFY commands, start pausing for a second before 562638032Speter processing each one. This avoids a certain form of denial 562738032Speter of service attack. Potential attack pointed out by Bryan 562838032Speter Costales. 562938032Speter Allow new named (not numbered!) config file rules to do validity 563038032Speter checking on SMTP arguments: check_mail for MAIL commands and 563138032Speter check_rcpt for RCPT commands. These rulesets can do anything 563238032Speter they want; their result is ignored unless they resolve to the 563338032Speter $#error mailer, in which case the indicated message is printed 563438032Speter and the command is rejected. Similarly, the check_compat 563538032Speter ruleset is called before delivery with "from_addr $| to_addr" 563638032Speter (the $| is a meta-symbol used to separate the two addresses); 563738032Speter it can give a "this sender can't send to this recipient" 563838032Speter notification. Note that this patch allows $| to stand alone 563938032Speter in rulesets. 564038032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 564138032Speter that have the name, IP address, and port number (respectively) 564238032Speter of the SMTP client (that is, the entity at the other end of 564338032Speter the connection. These can be used in (e.g.) check_rcpt to 564438032Speter verify that someone isn't trying to relay mail through your 564538032Speter host inappropriately. Be sure to use the deferred evaluation 564638032Speter form, for example $&{client_name}, to avoid having these bound 564738032Speter when sendmail reads the configuration file. 564838032Speter Add new config file rule check_relay to check the incoming connection 564938032Speter information. Like check_compat, it is passed the host name 565038032Speter and host address separated by $| and can reject connections 565138032Speter on that basis. 565238032Speter Allow IDA-style recursive function calls. Code contributed by Mark 565338032Speter Lovell and Paul Vixie. 565438032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 565538032Speter a virtual UUCP address using either a domain address or the $k 565638032Speter macro. Based on code contributed by Mark Lovell and Paul 565738032Speter Vixie. 565838032Speter Add Stanford LDAP map. Requires special libraries that are not 565938032Speter included with sendmail. Contributed by Booker C. Bense 566038032Speter <bbense@networking.stanford.edu>; contact him for support. 566138032Speter See also the src/READ_ME file. 566238032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 566338032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 566438032Speter only for debugging deep bits of code where it is important to 566538032Speter distinguish between the single-character metasymbol $+ and the 566638032Speter two characters $, +. 566738032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 566838032Speter debug_dumpstate. 566938032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 567038032Speter files that are group writable are considered "unsafe" -- that 567138032Speter is, programs and files referenced from such files are not 567238032Speter valid recipients. 567338032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 567438032Speter name that was not in DNS or was a domain-literal. Problem 567538032Speter noted by Tom May. 567638032Speter Change the introduction to error messages to more clearly delineate 567738032Speter permanent from temporary failures; if both existed in a 567838032Speter single message it could be confusing. Suggested by John 567938032Speter Beck of InReference, Inc. 568038032Speter The IngoreDot (i) option didn't work for lines that were terminated 568138032Speter with CRLF. Problem noted by Ted Stockwell of Secure 568238032Speter Computing Corporation. 568338032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 568438032Speter message headers. Problem reported by Matt Dillon of Best 568538032Speter Internet Communications. 568638032Speter Check for bogus characters in the 0200-0237 range; since these are 568738032Speter used internally, very strange errors can occur if those 568838032Speter characters appear in headers. Problem noted by Anders Gertz 568938032Speter of Lysator. 569038032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 569138032Speter recipient mailer has the F=9 flag set, and only works on 569238032Speter text/plain body types. Code contributed by Marius Olafsson 569338032Speter of the University of Iceland. 569438032Speter Special case "postmaster" name so that it is always treated as lower 569538032Speter case in alias files regardless of configuration settings; 569638032Speter this prevents some potential problems where "Postmaster" or 569738032Speter "POSTMASTER" might not match "postmaster". In most cases 569838032Speter this change is a no-op. 569938032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 570038032Speter Costales. 570138032Speter The -a map flag was ignored for dequote maps. Problem noted by 570238032Speter Bryan Costales. 570338032Speter Fix core dump when a lookup of a class "prog" map returns no 570438032Speter response. Patch from Bryan Costales. 570538032Speter Log instances where sendmail is deferring or rejecting connections 570638032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 570738032Speter Include port number in process title for network daemons. Suggested 570838032Speter by Kyle Jones of UUNET. 570938032Speter Send ``double bounces'' (errors that occur when sending an error 571038032Speter message) to the address indicated in the DoubleBounceAddress 571138032Speter option (default: postmaster). Previously they were always 571238032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 571338032Speter Add new mode, -bD, that acts like -bd in all respects except that 571438032Speter it runs in foreground. This is useful for using with a 571538032Speter wrapper that "watches" system services. Suggested by Kyle 571638032Speter Jones of UUNET. 571738032Speter Fix botch in spacing around (parenthesized) comments in addresses 571838032Speter when the comment comes before the address. Patch from 571938032Speter Motonori Nakamura of Kyoto University. 572038032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 572138032Speter that are being bounced to postmaster, rather than "Returned 572238032Speter mail". This permits the person who is postmaster more 572338032Speter easily determine what messages are to their role as 572438032Speter postmaster versus bounces to mail they actually sent. Based 572538032Speter on a suggestion by Motonori Nakamura. 572638032Speter Add new value "time" for QueueSortOrder option; this causes the queue 572738032Speter to be sorted strictly by the time of submission. Note that 572843730Speter this can cause very bad behavior over slow lines (because 572938032Speter large jobs will tend to delay small jobs) and on nodes with 573038032Speter heavy traffic (because old things in the queue for hosts that 573138032Speter are down delay processing of new jobs). Also, this does not 573238032Speter guarantee that jobs will be delivered in submission order 573338032Speter unless you also set DeliveryMode=queue. In general, it should 573438032Speter probably only be used on the command line, and only in 573538032Speter conjunction with -qRhost.domain. In fact, there are very few 573638032Speter cases where it should be used at all. Based on an 573738032Speter implementation by Motonori Nakamura. 573838032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 573938032Speter the same manner as other rulesets. Previously a temporary 574038032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 574138032Speter of Stanford University. 574238032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 574338032Speter 5yz (permanent failure) code. The next MX host will still be 574438032Speter tried if the connection cannot be opened in the first place 574538032Speter or if the MAIL command returns a 4yz (temporary failure) code. 574638032Speter (It's hard to know what to do here, since neither RFC 974 nor 574738032Speter RFC 1123 specify when to proceed to the next MX host.) 574838032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 574938032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 575038032Speter This causes map lookups that get a temporary failure (e.g., 575138032Speter name server failure) to _not_ defer the delivery of the 575238032Speter message. This should only be used if your configuration file 575338032Speter is prepared to do something sensible in this case. Based on 575438032Speter an idea by Gregory Shapiro of WPI. 575538032Speter Fix problem finding network interface addresses. Patch from 575638032Speter Motonori Nakamura. 575738032Speter Don't reject qf entries that are not owned by your effective uid if 575890792Sgshapiro you are not running set-user-ID; this makes management of 575980785Sgshapiro certain kinds of firewall setups difficult. Patch 576080785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 576138032Speter Add persistent host status. This keeps the information normally 576238032Speter maintained within a single queue run in disk files that are 576338032Speter shared between sendmail instances. The HostStatusDirectory 576438032Speter is the directory in which the information is maintained. If 576538032Speter not set, persistent host status is turned off. If not a full 576638032Speter pathname, it is relative to the queue directory. A common 576738032Speter value is ".hoststat". 576838032Speter There are also two new operation modes: 576938032Speter * -bh prints the status of hosts that have had recent 577038032Speter connections. 577138032Speter * -bH purges the host statuses. No attempt is made to save 577238032Speter recent status information. 577338032Speter This feature was originally written by Paul Vixie of Vixie 577438032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 577538032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 577638032Speter with my insistence that things fit cleanly into the V8 577738032Speter framework is gratefully appreciated. 577838032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 577938032Speter operate). Avoids letting two sendmails on the local machine 578064562Sgshapiro open connections to the same remote host at the same time. 578138032Speter This reduces load on the other machine, but can cause mail to 578238032Speter be delayed (for example, if one sendmail is delivering a huge 578338032Speter message, other sendmails won't be able to send even small 578438032Speter messages). Also, it requires another file descriptor (for the 578538032Speter lock file) per connection, so you may have to reduce 578638032Speter ConnectionCacheSize to avoid running out of per-process 578738032Speter file descriptors. Based on the persistent host status code 578838032Speter contributed by Paul Vixie and Mark Lovell. 578938032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 579038032Speter SafeFileEnvironment option is set. Problem noted by Bryan 579138032Speter Costales. 579238032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 579338032Speter file. Problem noted by Bryan Costales. 579438032Speter If a job was aborted using the interrupt signal (e.g., control-C from 579538032Speter the keyboard), on some occasions an empty df file would be 579638032Speter left around; these would collect in the queue directory. 579738032Speter Problem noted by Bryan Costales. 579838032Speter Change the makesendmail script to enhance the search for Makefiles 579938032Speter based on release number. For example, on SunOS 5.5.1, it will 580038032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 580138032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 580238032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 580338032Speter Webmasters. 580438032Speter When creating maps using "newaliases", always map the keys to lower 580538032Speter case when creating the map unless the -f flag is specified on 580638032Speter the map itself. Previously this was done based on the F=u 580738032Speter flag in the local mailer, which meant you could create aliases 580838032Speter that you could never access. Problem noted by Bob Wu of DEC. 580938032Speter When a job was read from the queue, the bits causing notification on 581038032Speter failure or delay were always set. This caused those 581138032Speter notifications to be sent even if NOTIFY=NEVER had been 581238032Speter specified. Problem noted by Steve Hubert of the University 581338032Speter of Washington, Seattle. 581438032Speter Add new configurable routine validate_connection (in conf.c). This 581538032Speter lets you decide if you are willing to accept traffic from 581638032Speter this host. If it returns FALSE, all SMTP commands will return 581738032Speter "550 Access denied". -DTCPWRAPPERS will include support for 581838032Speter TCP wrappers; you will need to add -lwrap to the link line. 581938032Speter (See src/READ_ME for details.) 582038032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 582138032Speter bounces. Some people seemed to think that this could be 582238032Speter confusing (even though it is true). Suggested by Motonori 582338032Speter Nakamura. 582438032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 582538032Speter user early in processing to avoid potential security problems. 582638032Speter However, this means that all .forward and :include: files must 582738032Speter be readable by that user, and all files to be written must be 582838032Speter writable by that user and all programs will be executed by that 582938032Speter user. It is also incompatible with the SafeFileEnvironment 583038032Speter option. In other words, it may not actually add much to 583138032Speter security. However, it should be useful on firewalls and other 583238032Speter places where users don't have accounts and the aliases file is 583338032Speter well constrained. 583438032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 583538032Speter only on the first attempt to delivery to an address. It could 583638032Speter be set to be lower than Timeout.connect on the principle that 583738032Speter the mail should go through quickly to responsive hosts; less 583838032Speter responsive hosts get to wait for the next queue run. 583938032Speter Fix a problem on Solaris that occasionally causes programs 584038032Speter (such as vacation) to hang with their standard input connected 584138032Speter to a UDP port. It also created some signal handling problems. 584238032Speter The problems turned out to be an interaction between vfork(2) 584338032Speter and some of the libraries, particularly NIS/NIS+. I am 584438032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 584538032Speter Change user class map to do the same matching that actual delivery 584638032Speter will do instead of just a /etc/passwd lookup. This adds 584738032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 584838032Speter The Timeout.* options are not safe -- they can be used to create a 584938032Speter denial-of-service attack. Problem noted by Christophe 585038032Speter Wolfhugel. 585143730Speter Don't send PostmasterCopy messages in the event of a "delayed" 585238032Speter notification. Suggested by Barry Bouwsma. 585338032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 585438032Speter option is set, since this disables VERB mode. Suggested 585538032Speter by John Hawkinson of MIT. 585638032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 585738032Speter by Motonori Nakamura of Kyoto University. 585838032Speter Only queue messages on transient .forward open failures if there 585943730Speter were no successful opens. The previous behavior caused it 586038032Speter to queue even if a "fall back" .forward was found. Problem 586138032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 586238032Speter and Computer Science (DISCS), NUS, Singapore. 586338032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 586438032Speter is bouncing because of a MIME error during 8->7 bit conversion; 586538032Speter the encapsulated message will bounce again, causing a loop. 586638032Speter Problem noted by Steve Hubert of the University of Washington. 586738032Speter Create xf (transcript) files using the TempFileMode option value 586838032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 586938032Speter National University of Singapore. 587038032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 587138032Speter detect cases where DefaultUid is set to something that the 587238032Speter system can't cope with. 587338032Speter PORTABILITY FIXES: 587438032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 587538032Speter Atlas International. 587638032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 587738032Speter <bicknell@ufp.org>. 587838032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 587938032Speter work on the first recipient of a message due to a 588038032Speter bug in the getpwent family.

Contributed by 592538032Speter Robert La Ferla of Hot Software. 592638032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 592738032Speter (where "code" is an exit status) on domains (previously 592838032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 592938032Speter Foundation. 593038032Speter CONFIG: hooks for IPv6-style domain literals. 593138032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 593238032Speter if it is undefined the AliasFile option is never set; this 593338032Speter should be transparent for most everyone. Suggested by John 593438032Speter Myers of CMU. 593538032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 593638032Speter domain listed in $=w is masqueraded. With it, only those 593738032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 593838032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 593938032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 594038032Speter hosts under those domains as well as the domain headers 594138032Speter themselves. For example, if a configuration had 594238032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 594338032Speter foo.com would be masqueraded; with it, *.foo.com would be 594438032Speter masqueraded as well. Based on an implementation by Richard 594538032Speter (Pug) Bainter of U. Texas. 594638032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 594738032Speter outgoing addresses.

Yes, 594938032Speter this does overlap with the user database, and figuring out 595038032Speter just when to use which one may be tricky. Based on code 595138032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 595238032Speter from Per Hedeland of Ericsson. 595338032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 595438032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 595538032Speter Keys are either fully qualified addresses or just the host 595638032Speter part (with the @ sign). For example, a table containing: 595738032Speter info@foo.com foo-info 595838032Speter info@bar.com bar-info 595938032Speter @baz.org jane@elsewhere.net 596038032Speter would send all mail destined for info@foo.com to foo-info 596138032Speter (which is presumably an alias), mail addressed to info@bar.com 596238032Speter to bar-info, and anything addressed to anyone at baz.org will 596338032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 596438032Speter and baz.org must all be in $=w. Based on discussions with 596538032Speter a great many people. 596638032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 596738032Speter Suggested by Richard Bainter. 596838032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 596938032Speter "fax" mailer. 597038032Speter CONFIG: allow mailertable entries to resolve to local:user; this 597138032Speter passes the original user@host in to procmail-style local 597238032Speter mailers as the "detail" information to allow them to do 597338032Speter additional clever processing. From Joe Pruett of 597438032Speter Teleport Corporation. Delivery to the original user can 597538032Speter be done by specifying "local:" (with nothing after the colon). 597638032Speter CONFIG: allow any context that takes "mailer:domain" to also take 597738032Speter "mailer:user@domain" to force mailing to the given user; 597838032Speter "local:user" can also be used to do local delivery. This 597938032Speter applies on *_RELAY and in the mailertable entries. Based 598038032Speter on a suggestion by Ribert Kiessling of Easynet. 598138032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 598238032Speter limits the possible domains; this reduces the number of DNS 598338032Speter lookups required to support this feature. For example, 598438032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 598538032Speter to domains under my.site.com. Code contributed by Anthony 598638032Speter Thyssen <anthony@cit.gu.edu.au>. 598738032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 598838032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 598938032Speter of WPI. 599038032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 599138032Speter event you have to define local mailers. Suggested by 599238032Speter Gregory Shapiro of WPI. 599338032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 599438032Speter be misinterpreted as a list:...; syntax. Based on a patch by 599538032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 599638032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 599738032Speter remotely connected. The address host!user was being 599838032Speter converted to host!user@thishost instead of host!user@uurelay. 599938032Speter Problem noted by William Gianopoulos of Raytheon Company. 600038032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 600138032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 600238032Speter "User has moved"; the former wording was confusing if the 600338032Speter new address is still on the local host. Based on a suggestion 600438032Speter by Andreas Luik. 600538032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 600638032Speter However, the class is not pre-initialized to contain root. 600738032Speter Suggested by Gregory Neil Shapiro. 600838032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 600938032Speter Wolfhugel. 601038032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 601138032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 601238032Speter well: this produces a slightly different mailbox format (no 601338032Speter Content-Length: headers), file ownerships and modes are 601438032Speter different (not owned by group mail; mode 600 instead of 660), 601538032Speter and the local mailer flags will have to be tweaked (make them 601638032Speter match bsd4.4) in order to use this mailer. Patches from Paul 601738032Speter Hammann of the Missouri Research and Education Network. 601838032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 601938032Speter was a delivery error, such as if the ownership on the file 602038032Speter was wrong or the mode changed between the initial stat and 602138032Speter the open. Problem reported by William Colburn of the New 602238032Speter Mexico Institute of Mining and Technology. 602338032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 602438032Speter Costales. 602538032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 602638032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 602738032Speter honored. Fix from Michael Scott Shappe. 602838032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 602938032Speter NEW FILES: 603038032Speter src/Makefiles/Makefile.AIX.2 603138032Speter src/Makefiles/Makefile.IRIX.6.2 603238032Speter src/Makefiles/Makefile.maxion 603338032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 603438032Speter src/Makefiles/Makefile.SCO.5.x 603538032Speter src/Makefiles/Makefile.UXPDSV20 603638032Speter mailstats/mailstats.8 603738032Speter praliases/praliases.8 603838032Speter cf/cf/generic-nextstep3.3.mc 603938032Speter cf/feature/genericstable.m4 604038032Speter cf/feature/limited_masquerade.m4 604138032Speter cf/feature/masquerade_entire_domain.m4 604238032Speter cf/feature/virtusertable.m4 604338032Speter cf/ostype/aix2.m4 604438032Speter cf/ostype/altos.m4 604538032Speter cf/ostype/maxion.m4 604638032Speter cf/ostype/solaris2.ml.m4 604738032Speter cf/ostype/uxpds.m4 604838032Speter contrib/re-mqueue.pl 604938032Speter DELETED FILES: 605038032Speter src/Makefiles/Makefile.Solaris 605138032Speter contrib/xla/README 605238032Speter contrib/xla/xla.c 605338032Speter RENAMED FILES: 605438032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 605538032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 605638032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 605738032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 605838032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 605938032Speter 606064562Sgshapiro8.7.6/8.7.3 1996/09/17 606138032Speter SECURITY: It is possible to force getpwuid to fail when writing the 606238032Speter queue file, causing sendmail to fall back to running programs 606338032Speter as the default user. This is not exploitable from off-site. 606438032Speter Workarounds include using a unique user for the DefaultUser 606538032Speter (old u & g options) and using smrsh as the local shell. 606638032Speter SECURITY: fix some buffer overruns; in at least one case this allows 606738032Speter a local user to get root. This is not known to be exploitable 606838032Speter from off-site. The workaround is to disable chfn(1) commands. 606938032Speter 607064562Sgshapiro8.7.5/8.7.3 1996/03/04 607138032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 607238032Speter in some case cause connections to hang or messages to have 607338032Speter extra spaces in odd places. Patch from Eric Wassenaar; 607438032Speter reports from Eric Hall of Chiron Corporation, Stephen 607538032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 607638032Speter and others. 607738032Speter 607864562Sgshapiro8.7.4/8.7.3 1996/02/18 607938032Speter SECURITY: In some cases it was still possible for an attacker to 608038032Speter insert newlines into a queue file, thus allowing access to 608138032Speter any user (except root). 608238032Speter CONFIG: no changes -- it is not a bug that the configuration 608338032Speter version number is unchanged. 608438032Speter 608564562Sgshapiro8.7.3/8.7.3 1995/12/03 608638032Speter Fix botch in name server timeout in RCPT code; this problem caused 608738032Speter two responses in SMTP, which breaks things horribly. Fix 608838032Speter from Gregory Neil Shapiro of WPI. 608938032Speter Verify that L= value on M lines cannot be negative, which could cause 609038032Speter negative array subscripting. Not a security problem since 609138032Speter this has to be in the config file, but it could have caused 609238032Speter core dumps. Pointed out by Bryan Costales. 609338032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 609438032Speter Costales. 609538032Speter PORTABILITY FIXES: 609638032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 609738032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 609838032Speter order. Tweak it to work properly. Based on fixes 609938032Speter from Fletcher Mattox of UTexas and Betty Lee of 610038032Speter Stanford University. 610138032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 610238032Speter Deficiency pointed out by Bryan Costales of ICSI. 610338032Speter 610464562Sgshapiro8.7.2/8.7.2 1995/11/19 610538032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 610638032Speter OperatorChars, and UnixFromLine options. They were not 610738032Speter properly repaired in 8.7.1. 610838032Speter Completely delete the Bcc: header if and only if there are other 610938032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 611038032Speter last being a historic botch, of course). If Bcc: is the 611138032Speter only recipient header in the message, its value is tossed, 611243730Speter but the header name is kept. The old behavior (always keep 611338032Speter the header name and toss the value) allowed primary recipients 611438032Speter to see that a Bcc: went to _someone_. 611538032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 611638032Speter sender to <address> using -f'' syslog messages. Suggested 611738032Speter by Kari Hurtta. 611838032Speter If a sequence or switch map lookup entry gets a tempfail but then 611938032Speter continues on to another map type, but the name is not found, 612038032Speter return a temporary failure from the sequence or switch map. 612138032Speter For example, if hosts search ``dns files'' and DNS fails 612238032Speter with a tempfail, the hosts map will go on and search files, 612338032Speter but if it fails the whole thing should be a tempfail, not 612438032Speter a permanent (host unknown) failure, even though that is the 612538032Speter failure in the hosts.files map. This error caused hard 612638032Speter bounces when it should have requeued. 612738032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 612890792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 612938032Speter working properly due to excessive paranoia. Pointed out by 613038032Speter John Hawkinson of Panix. 613138032Speter An SMTP RCPT command referencing a host that gave a nameserver 613238032Speter timeout would return a 451 command (8.6 accepted it and 613343730Speter queued it locally). Revert to the 8.6 behavior in order 613438032Speter to simplify queue management for clustered systems. Suggested 613538032Speter by Gregory Neil Shapiro of WPI. The same problem could break 613638032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 613738032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 613838032Speter Infobiogen. 613938032Speter Fix possible buffer overflow in munchstring(). This was not a security 614038032Speter problem because you couldn't specify any argument to this 614138032Speter without first giving up root privileges, but it is still a 614238032Speter good idea to avoid future problems. Problem noted by John 614338032Speter Hawkinson and Sam Hartman of MIT. 614438032Speter ``452 Out of disk space for temp file'' messages weren't being 614538032Speter printed. Fix from David Perlin of Nanosoft. 614643730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 614738032Speter is not set, since this is required to get the actual DSNs 614838032Speter created. Problem pointed out by John Gardiner Myers of CMU. 614938032Speter Log permission problems that cause .forward and :include: files to 615038032Speter be untrusted or ignored on log level 12 and higher. Suggested 615138032Speter by Randy Martin of Clemson University. 615238032Speter Allow user ids in U= clauses of M lines to have hyphens and 615338032Speter underscores. 615438032Speter Fix overcounting of recipients -- only happened when sending to an 615538032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 615638032Speter of Systems and Computer Technology Corporation. 615738032Speter If a message is sent to an address that fails, the error message that 615838032Speter is returned could show some extraneous "success" information 615938032Speter included even if the user did not request success notification, 616038032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 616138032Speter Config files that had no AliasFile definition were defaulting to 616238032Speter using /etc/aliases; this caused problems with nullclient 616338032Speter configurations. Change it back to the 8.6 semantics of 616438032Speter having no local alias file unless it is declared. Problem 616538032Speter noted by Charles Karney of Princeton University. 616638032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 616738032Speter Costales of ICSI. 616838032Speter Map lookups of class "userdb" maps were always case sensitive; they 616938032Speter should be controlled by the -f flag like other maps. Pointed 617038032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 617138032Speter Fix problem that caused some addresses to be passed through ruleset 5 617238032Speter even when they were tagged as "sticky" by prefixing the 617338032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 617438032Speter Technological University. 617538032Speter When converting a message to Quoted-Printable, prevent any lines with 617638032Speter dots alone on a line by themselves. This is because of the 617738032Speter preponderance of broken mailers that still get this wrong. 617838032Speter Code contributed by Per Hedeland of Ericsson. 617938032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 618038032Speter out by Bjart Kvarme of USIT/UiO (Norway). 618138032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 618238032Speter Requested by Allan Johannesen. 618338032Speter Delete check for text format of alias files -- it should be legal 618438032Speter to have the database format of the alias files without the 618538032Speter text version. Problem pointed out by Joe Rhett of Navigist, 618638032Speter Inc. 618738032Speter If "Ot" was specified with no value, the TZ variable was not properly 618838032Speter imported from the environment. Pointed out by Frank Crawford 618938032Speter <frank@ansto.gov.au>. 619038032Speter Some architectures core dumped on "program" maps that didn't have 619138032Speter extra arguments. Patch from Booker C. Bense of Stanford 619238032Speter University. 619338032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 619438032Speter the parent should do this. Fix from Brian Coan of the 619538032Speter Association for Progressive Communications. 619638032Speter If MinQueueAge was set and a message was considered but not run 619738032Speter during a queue run and the Timeout.queuereturn interval was 619838032Speter reached, a "timed out" error message would be returned that 619938032Speter didn't include the failed address (and claimed to be a warning 620038032Speter even though it was fatal). The fix is to not return such 620138032Speter messages until they are actually tried, i.e., in the next 620238032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 620338032Speter SINTEF RUNIT, Oslo. 620438032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 620538032Speter that have the hes_getmailhost() routine.

Bug 625238032Speter pointed out by John Hawkinson of MIT. 625338032Speter Fix strange case of an executable called by a program map that 625438032Speter returns a value but also a non-zero exit status; this 625538032Speter would give contradictory results in the higher level; in 625638032Speter particular, the default clause in the map lookup would be 625738032Speter ignored. Change to ignore the value if the program returns 625838032Speter non-zero exit status. From Tom Moore of AT&T GIS. 625938032Speter Shorten parameters passed to syslog() in some contexts to avoid a 626038032Speter bug in many vendors' implementations of that routine. Although 626138032Speter this isn't really a bug in sendmail per se, and my solution 626238032Speter has to assume that syslog() has at least a 1K buffer size 626338032Speter internally (I know some vendors have shortened this 626438032Speter dramatically -- they're on their own), sendmail is a popular 626538032Speter target. Also, limit the size of %s arguments in sprintf. 626638032Speter These both have possible security implications. Solutions 626738032Speter suggested by Casper Dik of Sun's Network Security Group 626838032Speter (Holland), Mark Seiden, and others. 626938032Speter Fix a problem that might cause a non-standard -B (body type) 627038032Speter parameter to be passed to the next server with undefined 627138032Speter results. This could have security implications. 627238032Speter If a filesystem was at > 100% utilization, the freediskspace() 627338032Speter routine incorrectly returned an error rather than zero. 627438032Speter Problem noted by G. Paul Ziemba of Alantec. 627538032Speter Change MX sort order so that local hostnames (those in $=w) always 627638032Speter sort first within a given preference. This forces the bestmx 627738032Speter map to always return the local host first, if it is included 627838032Speter in the list of highest priority MX records. From K. Robert 627938032Speter Elz. 628038032Speter Avoid some possible null pointer dereferences. Fixes from Randy 628138032Speter Martin <WOLF@CLEMSON.EDU> 628238032Speter When sendmail starts up on systems that have no fully qualified 628338032Speter domain name (FQDN) anywhere in the first matching host map 628438032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 628538032Speter sendmail would sleep to try to find a FQDN, which it really 628638032Speter really needs. This has been changed to fall through to the 628738032Speter next map type if it can't find a FQDN -- i.e., if the hosts 628838032Speter file doesn't have a FQDN, it will try dns even though the 628938032Speter short name was found in /etc/hosts. This is probably a crock, 629038032Speter but many people have hosts files without FQDNs. Remember: 629138032Speter domain names are your friends. 629238032Speter Log a high-priority message if you can't find your FQDN during startup. 629338032Speter Suggested by Simon Barnes of Schlumberger Limited. 629438032Speter When using Hesiod, initialize it early to improve error reporting. 629538032Speter Patch from Don Lewis of Silicon Systems, Inc. 629638032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 629738032Speter connection timeout in the kernel. Add a new "connect" timeout 629838032Speter to limit this time. Defaults to zero (use whatever the 629938032Speter kernel provides). Based on code contributed by J.R. Oldroyd 630038032Speter of TerraNet. 630138032Speter Under some circumstances, a failed message would not be properly 630238032Speter removed from the queue, causing tons of bogus error messages. 630338032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 630438032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 630538032Speter of WPI. 630638032Speter PORTABILITY FIXES: 630738032Speter On IRIX 5.x, there was an inconsistency in the setting 630838032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 632438032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 632538032Speter otherwise the F=S causes the From_ line to imply that root is 632638032Speter the sender. Problem pointed out by Claude Scarpelli of 632738032Speter Infobiogen (France). 632838032Speter NEW FILES: 632938032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 633038032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 633138032Speter src/Makefiles/Makefile.UXPDS 633238032Speter 633364562Sgshapiro8.7/8.7 1995/09/16 633438032Speter Fix a problem that could cause sendmail to run out of file 633538032Speter descriptors due to a trashed data structure after a 633638032Speter vfork.

This was used "safely" in the sense 634238032Speter that it only did a stat, but it would have set the 634338032Speter map modification time improperly. Problem pointed out 634438032Speter by Roy Mongiovi of Georgia Tech. 634538032Speter Clean up the Subject: line on warning messages and return 634638032Speter receipts so that they don't say "Returned mail:"; this 634738032Speter can be confusing. 634838032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 634938032Speter useful enough to make it worthwhile printing on "-d". 635038032Speter Avoid logging alias statistics every time you read the alias 635138032Speter file on systems with no database method compiled in. 635238032Speter If you have a name with a trailing dot, and you try looking it 635338032Speter up using gethostbyname without the dot (for /etc/hosts 635438032Speter compatibility), be sure to turn off RES_DEFNAMES and 635538032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 635638032Speter Problem noted by Charles Amos of the University of 635738032Speter Maryland. 635838032Speter Don't do timeouts in collect if you are not running SMTP. 635938032Speter There is nothing that says you can't have a long 636038032Speter running program piped into sendmail (possibly via 636138032Speter /bin/mail, which just execs sendmail). Problem reported 636238032Speter by Don "Truck" Lewis of Silicon Systems. 636338032Speter Try gethostbyname() even if the DNS lookup fails iff option I 636438032Speter is not set. This allows you to have hosts listed in 636538032Speter NIS or /etc/hosts that are not known to DNS. It's normally 636638032Speter a bad idea, but can be useful on firewall machines. This 636738032Speter should really be broken out on a separate flag, I suppose. 636838032Speter Avoid compile warnings against BIND 4.9.3, which uses function 636938032Speter prototypes.

From Kyle Jones of UUNET. 637438032Speter SECURITY: avoid denial-of-service attacks possible by destroying 637538032Speter the alias database file by setting resource limits low. 637638032Speter This involves adding two new compile-time options: 637738032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 637838032Speter available) and HASULIMIT (indicating that ulimit(2) support 637938032Speter is available -- the Release 3 form is used). The former 638038032Speter is assumed on BSD-based systems, the latter on System 638138032Speter V-based systems. Attack noted by Phil Brandenberger of 638238032Speter Swarthmore University. 638338032Speter New syntaxes in test (-bt) mode: 638438032Speter ``.Dmvalue'' will define macro "m" to "value". 638538032Speter ``.Ccvalue'' will add "value" to class "c". 638638032Speter ``=Sruleset'' will dump the contents of the indicated 638738032Speter ruleset. 638838032Speter ``=M'' will display the known mailers. 638938032Speter ``-ddebug-spec'' is equivalent to the command-line 639038032Speter -d debug flag. 639138032Speter ``$m'' will print the value of macro $m. 639238032Speter ``$=c'' will print the contents of class $=c. 639338032Speter ``/mx host'' returns the MX records for ``host''. 639438032Speter ``/parse address'' will parse address, returning the value of 639538032Speter crackaddr (essentially, the comment information) 639638032Speter and the parsed address. 639738032Speter ``/try mailer address'' will rewrite address into the form 639838032Speter it will have when presented to the indicated mailer. 639938032Speter ``/tryflags flags'' will set flags used by parsing. The 640038032Speter flags can be `H' for header or `E' for envelope, 640138032Speter and `S' for sender or `R' for recipient. These 640238032Speter can be combined, so `HR' sets flags for header 640338032Speter recipients. 640438032Speter ``/canon hostname'' will try to canonify hostname and 640538032Speter return the result. 640638032Speter ``/map mapname key'' will look up `key' in the indicated 640738032Speter `mapname' and return the result. 640838032Speter Somewhat better handling of UNIX-domain socket addresses -- it 640938032Speter should show the pathname rather than hex bytes. 641038032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 641138032Speter the header for envelope sender information and uses 641238032Speter CR-LF as message terminators. It was thought to be 641338032Speter obsolete (used only for Arpanet NCP protocols), but it 641438032Speter turns out that the UK ``Grey Book'' protocols require 641538032Speter that functionality. 641638032Speter Fix a fix in previous release -- if gethostname and gethostbyname 641738032Speter return a name without dots, and if an attempt to canonify 641838032Speter that name fails, wait one minute and try again. This can 641938032Speter result in an extra 60 second delay on startup if your system 642038032Speter hostname (as returned by hostname(1)) has no dot and no names 642138032Speter listed in /etc/hosts or your NIS map have a dot. 642238032Speter Check for proper domain name on HELO and EHLO commands per 642338032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 642438032Speter of Michigan Technological University. 642538032Speter Relax chownsafe rules slightly -- old version said that if you 642638032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 642738032Speter if fpathconf returned EINVAL or ENOSYS), assume that 642838032Speter chown is not safe. The new version falls back to whether 642938032Speter you are on a BSD system or not. This is important for 643038032Speter SunOS, which apparently always returns one of those 643138032Speter error codes. This impacts whether you can mail to files 643238032Speter or not. 643338032Speter Syntax errors such as unbalanced parentheses in the configuration 643438032Speter file could be omitted if you had "Oem" prior to the 643538032Speter syntax error in the config file. Change to always print 643638032Speter the error message. It was especially weird because it 643738032Speter would cause a "warning" message to be sent to the Postmaster 643838032Speter for every message sent (but with no transcript). Problem 643938032Speter noted by Gregory Paris of Motorola. 644038032Speter Rewrite collect and putbody to handle full 8-bit data, including 644138032Speter zero bytes.

This is to handle the 651038032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 651138032Speter assume that ``group name:'' is a comment on the first 651238032Speter address and the ``;'' is a comment on the last address). 651338032Speter This requires config file support to get right. It does 651438032Speter understand that :: is NOT this syntax, and can be turned 651538032Speter off completely by setting the ColonOkInAddresses option. 651638032Speter Level 6 config files added with new mailer flags: 651738032Speter A Addresses are aliasable. 651838032Speter i Do udb rewriting on envelope as well as header 651938032Speter sender lines. Applies to the from address mailer 652038032Speter flags rather than the recipient mailer flags. 652138032Speter j Do udb rewriting on header recipient addresses. 652238032Speter Applies to the sender mailer flags rather than the 652338032Speter recipient mailer flags. 652438032Speter k Disable check for loops when doing HELO command. 652538032Speter o Always run as the mail recipient, even on local 652638032Speter delivery. 652738032Speter w Check for an /etc/passwd entry for this user. 652838032Speter 5 Pass addresses through ruleset 5. 652938032Speter : Check for :include: on this address. 653038032Speter | Check for |program on this address. 653138032Speter / Check for /file on this address. 653238032Speter @ Look up sender header addresses in the user 653338032Speter database. Applies to the mailer flags for the 653438032Speter mailer corresponding to the envelope sender 653538032Speter address, rather than to recipient mailer flags. 653638032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 653738032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 653838032Speter mailers, and the ColonOkInAddresses option. 653938032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 654038032Speter John Beck of Hewlett-Packard, who generously contributed 654138032Speter their implementation to me, which I then didn't use (see 654238032Speter mime.c for an explanation of why). This adds the 654338032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 654438032Speter to control handling of 8-bit data. These have to cope with 654538032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 654638032Speter 8-bit data that is entered without declaring it as 8-bit 654738032Speter MIME -- technically this is illegal according to the 654838032Speter specs) and labelled 8-bit data (that is, it was declared 654938032Speter as 8BITMIME in the ESMTP session or by using the 655038032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 655138032Speter set then 8-bit data is sent to non-8BITMIME machines 655238032Speter instead of converting to 7 bit (essentially using 655338032Speter just-send-8 semantics). The values for EightBitMode are: 655438032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 655538032Speter any necessary conversion of 8BITMIME to 7BIT 655638032Speter (essentially, the full MIME option). 655738032Speter p pass unlabelled 8-bit input, but convert labelled 655838032Speter 8BITMIME input to 7BIT as required (default). 655938032Speter s strict adherence: reject unlabelled 8-bit input, 656038032Speter convert 8BITMIME to 7BIT as required. The F=8 656138032Speter flag is ignored. 656238032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 656338032Speter the setting of F=8. 656438032Speter Add new internal class 'n', which is the set of MIME Content-Types 656538032Speter which can not be 8 to 7 bit encoded because of other 656638032Speter considerations. Types "multipart/*" and "message/*" are 656738032Speter never directly encoded (although their components can be). 656838032Speter Add new internal class 's', which is the set of subtypes of the 656938032Speter MIME message/* content type that can be treated as though 657038032Speter they are an RFC822 message. It is predefined to have 657138032Speter "rfc822". Suggested By Kari Hurtta. 657238032Speter Add new internal class 'e'. This is the set of MIME 657338032Speter Content-Transfer-Encodings that can be converted to 657438032Speter a seven bit format (Quoted-Printable or Base64). It is 657538032Speter preinitialized to contain "7bit", "8bit", and "binary". 657638032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 657738032Speter short name) to set the default character set to use in the 657838032Speter Content-Type: header when doing encoding of an 8-bit message 657938032Speter which isn't marked as MIME into MIME format. If the C= 658038032Speter parameter is set on the Envelope From address, use that as 658138032Speter the default encoding; else use the DefaultCharSet option. 658238032Speter If neither is set, it defaults to "unknown-8bit" as 658338032Speter suggested by RFC 1428 section 3. 658438032Speter Allow ``U=user:group'' field in mailer definition to set a default 658538032Speter user and group that a mailer will be executed as. This 658638032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 658738032Speter also set, it is the uid/gid that will always be used (that 658838032Speter is, the controlling address is ignored). The values may be 658938032Speter numeric or symbolic; if only a symbolic user is given (no 659038032Speter group) that user's default group in the passwd file is used 659138032Speter as the group. Based on code donated by Chip Rosenthal of 659238032Speter Unicom. 659338032Speter Allow `u' option to also accept user:group as a value, in the same 659438032Speter fashion as the U= mailer option. 659538032Speter Add the symbolic time zone name in the Arpanet format dates (as 659638032Speter a comment). This adds a new compile-time configuration 659738032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 659838032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 659938032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 660038032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 660138032Speter timezone()), or TZ_NONE (don't include the comment). Code 660238032Speter from Chip Rosenthal. 660338032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 660438032Speter For example, 660538032Speter O Timeout.helo = 2m 660638032Speter There are also two new suboptions "queuereturn" and 660738032Speter "queuewarn"; these subsume the old T option. Thus, to 660838032Speter set them both the preferred new syntax is 660938032Speter O Timeout.queuereturn = 5d 661038032Speter O Timeout.queuewarn = 4h 661138032Speter Sort queue by host name instead of by message priority if the 661238032Speter QueueSortOrder option (no short name) is set is set to 661338032Speter ``host''. This makes better use of the connection cache, 661438032Speter but may delay more ``interactive'' messages behind large 661538032Speter backlogs under some circumstances. This is probably a 661638032Speter good option if you have high speed links or don't do lots 661738032Speter of ``batch'' messages, but less good if you are using 661838032Speter something like PPP on a 14.4 modem. Based on code 661938032Speter contributed by Roy Mongiovi of Georgia Tech (my main 662038032Speter contribution was to make it configurable). 662138032Speter Save i-number of df file in qf file to simplify rebuilding of queue 662238032Speter after disastrous disk crash. Suggested by Kyle Jones of 662338032Speter UUNET; closely based on code from KJS DECWRL code written 662438032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 662538032Speter are NOT back compatible with 8.6 -- that is, you can convert 662638032Speter from 8.6 to 8.7, but not the other direction. 662738032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 662838032Speter route-addrs in envelopes; this is because in some cases 662938032Speter they can be sent to the shell, which interprets them as 663038032Speter I/O redirection. 663138032Speter Don't include error file (option E) with return-receipts; this 663238032Speter can be confusing. 663338032Speter Don't send "Warning: cannot send" messages to owner-* or 663438032Speter *-request addresses. Suggested by Christophe Wolfhugel 663538032Speter of the Institut Pasteur, Paris. 663638032Speter Allow -O command line flag to set long form options. 663738032Speter Add "MinQueueAge" option to set the minimum time between attempts 663838032Speter to run the queue. For example, if the queue interval 663938032Speter (-q value) is five minutes, but the minimum queue age 664038032Speter is fifteen minutes, jobs won't be tried more often than 664138032Speter once every fifteen minutes. This can be used to give 664238032Speter you more responsiveness if your delivery mode is set to 664338032Speter queue-only. 664438032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 664538032Speter :include: and .forward files. 664638032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 664738032Speter key field name, the value field name, and the field 664838032Speter delimiter. The field delimiter can be a single character 664938032Speter or the sequence "\t" or "\n" for tab or newline. 665038032Speter These are for use by NIS+ and similar access methods. 665138032Speter Change maps to always strip quotes before lookups; the -q flag 665243730Speter turns off this behavior. Suggested by Motonori Nakamura. 665338032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 665438032Speter key and value field names respectively. Code donated by 665538032Speter Sun Microsystems. 665638032Speter Add "hesiod" map class. The "file name" is used as the 665738032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 665838032Speter first value found for the match. Code donated by Scott 665938032Speter Hutton of Indiana University. 666038032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 666138032Speter specify the name of the property that is searched as the 666238032Speter key and a -v flag to specify the name of the property that 666338032Speter is returned as the value (defaults to "members"). The 666438032Speter default map is "/aliases". Some code based on code 666538032Speter contributed by Robert La Ferla of Hot Software. 666638032Speter Add "text" map class. This does slow, linear searches through 666738032Speter text files. The -z flag specifies a column delimiter 666838032Speter (defaults to any sequence of white space), the -k flag 666938032Speter sets the key column number, and the -v flag sets the 667038032Speter value column number. Lines beginning with `#' are treated 667138032Speter as comments. 667238032Speter Add "program" map class to execute arbitrary programs. The search 667338032Speter key is presented as the last argument; the output is one 667438032Speter line read from the programs standard output. Exit statuses 667538032Speter are from sysexits.h. 667638032Speter Add "sequence" map class -- searches maps in sequence until it 667738032Speter finds a match. For example, the declarations: 667838032Speter Kmap1 ... 667938032Speter Kmap2 ... 668038032Speter Kmapseq sequence map1 map2 668138032Speter defines a map "mapseq" that first searches map1; if the 668238032Speter value is found it is returned immediately, otherwise 668338032Speter map2 is searched and the value returned. 668438032Speter Add "switch" map class. This is much like "sequence" except that 668538032Speter the ordering is fetched from an external file, usually 668638032Speter the system service switch. The parameter is the name of 668738032Speter the service to switch on, and the maps that it will use 668838032Speter are the name of the switch map followed by ".service_type". 668938032Speter For example, if the declaration of the map is 669038032Speter Ksample switch hosts 669138032Speter and the system service switch specifies that hosts are 669238032Speter looked up using dns and nis in that order, then this is 669338032Speter equivalent to 669438032Speter Ksample sequence sample.dns sample.nis 669538032Speter The subordinate maps (sample.*) must already be defined. 669638032Speter Add "user" map class -- looks up users using getpwnam. Takes a 669738032Speter "-v field" flag on the definition that tells what passwd 669838032Speter entry to return -- legal values are name, passwd, uid, gid, 669938032Speter gecos, dir, and shell. Generally expected to be used with 670038032Speter the -m (matchonly) flag. 670138032Speter Add "bestmx" map class -- returns the best MX value for the host 670238032Speter listed as the value. If there are several "best" MX records 670338032Speter for this host, one will be chosen at random. 670438032Speter Add "userdb" map class -- looks up entries in the user database. 670538032Speter The "file name" is actually the tag that will be used, 670638032Speter typically "mailname". If there are multiple entries 670738032Speter matching the name, the one chosen is undefined. 670838032Speter Add multiple queue timeouts (both return and warning). These are 670938032Speter set by the Precedence: or Priority: header fields to one of 671038032Speter three values. If a Priority: is set and has value "normal", 671164562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 671238032Speter used. If no priority is set, the Precedence: is consulted; 671338032Speter if negative, non-urgent timeouts are used; if greater than 671438032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 671538032Speter are used. The timeouts are set by setting the six timeouts 671638032Speter queue{warn,return}.{urgent,normal,non-urgent}. 671738032Speter Fix problem when a mail address is resolved to a $#error mailer 671838032Speter with a temporary failure indication; it works in SMTP, 671938032Speter but when delivering locally the mail is silently discarded. 672038032Speter This patch, from Kyle Jones of UUNET, bounces it instead 672138032Speter of queueing it (queueing is very hard). 672238032Speter When using /etc/hosts or NIS-style lookups, don't assume that 672338032Speter the first name in the list is the best one -- instead, 672438032Speter search for the first one with a dot. For example, if 672538032Speter an /etc/hosts entry reads 672638032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 672738032Speter this change will use the second name as the canonical 672838032Speter machine name instead of the initial, unqualified name. 672938032Speter Change dequote map to replace spaces in quoted text with a value 673038032Speter indicated by the -s flag on the dequote map definition. 673138032Speter For example, ``Mdequote dequote -s_'' will change 673238032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 673338032Speter quoted (because of the space character). Suggested by Dan 673438032Speter Oscarsson for use in X.400 addresses. 673538032Speter Implement long macro names as ${name}; long class names can 673638032Speter be similarly referenced as $={name} and $~{name}. 673738032Speter Definitions are (e.g.) ``D{name}value''. Names that have 673838032Speter a leading lower case letter or punctuation characters are 673938032Speter reserved for internal use by sendmail; i.e., config files 674038032Speter should use names that begin with a capital letter. Based 674138032Speter on code contributed by Dan Oscarsson. 674238032Speter Fix core dump if getgrgid returns a null group list (as opposed 674338032Speter to an empty group list, that is, a pointer to a list 674438032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 674538032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 674638032Speter failed, it called syserr which called newstr which called 674738032Speter xalloc.... The newstr is now avoided for "panic" messages. 674838032Speter Reported by Stuart Kemp of James Cook University. 674938032Speter Improve connection cache timeouts; previously, they were not even 675038032Speter checked if you were delivering to anything other than an 675138032Speter IPC-connected host, so a series of (say) local mail 675238032Speter deliveries could cause cached connections to be open 675338032Speter much longer than the specified timeout. 675438032Speter If an incoming message exceeds the maximum message size, stop 675538032Speter writing the incoming bytes to the queue data file, since 675638032Speter this can fill your mqueue partition -- this is a possible 675738032Speter denial-of-service attack. 675838032Speter Don't reject all numeric local user names unless HESIOD is 675938032Speter defined. It turns out that Posix allows all-numeric 676038032Speter user names. Fix from Tony Sanders of BSDI. 676138032Speter Add service switch support. If the local OS has a service 676238032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 676338032Speter on DEC systems) that will be used; otherwise, it falls back 676438032Speter to using a local mechanism based on the ServiceSwitchFile 676538032Speter option (default: /etc/service.switch). For example, if the 676638032Speter service switch lists "files" and "nis" for the aliases 676738032Speter service, that will be the default lookup order. the "files" 676838032Speter ("local" on DEC) service type expands to any alias files 676938032Speter you listed in the configuration file, even if they aren't 677038032Speter actually file lookups. 677138032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 677238032Speter variable which tells whether or not DNS should be considered 677338032Speter canonical. This is now determined based on whether or not 677438032Speter "dns" is in the service list for "hosts". 677538032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 677638032Speter Status Notifications). DSN notifications override 677738032Speter Return-Receipt-To: headers, which are bogus anyhow -- 677838032Speter support for them has been removed. 677938032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 678038032Speter definitions to define the types used in DSN returns for 678138032Speter MTA names, addresses, and diagnostics respectively. 678238032Speter Extend heuristic to force running in ESMTP mode to look for the 678338032Speter five-character string "ESMTP" anywhere in the 220 greeting 678438032Speter message (not just the second line). This is to provide 678538032Speter better compatibility with other ESMTP servers. 678638032Speter Print sequence number of job when running the queue so you can 678738032Speter easily see how much progress you have made. Suggested 678838032Speter by Peter Wemm of DIALix. 678938032Speter Map newlines to spaces in logged message-ids; some versions of 679038032Speter syslog truncate the rest of the line after newlines. 679138032Speter Suggested by Fletcher Mattox of U. Texas. 679238032Speter Move up forking for job runs so that if a message is split into 679338032Speter multiple envelopes you don't get "fork storms" -- this 679438032Speter also improves the connection cache utilization. 679538032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 679638032Speter the purposes of refusing to send error returns. Suggested 679738032Speter by Motonori Nakamura of Ritsumeikan University. 679838032Speter Relax rules on when a file can be written when referenced from 679938032Speter the aliases file: use the default uid/gid instead of the 680038032Speter real uid/gid. This allows you to create a file owned by 680138032Speter and writable only by the default uid/gid that will work 680290792Sgshapiro all the time (without having the set-user-ID bit set). Change 680338032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 680438032Speter Microsystems. 680538032Speter Add "DialDelay" option (no short name) to provide an "extra" 680638032Speter delay for dial on demand systems. If this is non-zero 680738032Speter and a connect fails, sendmail will wait this long and 680838032Speter then try again. If it takes longer than the kernel 680938032Speter timeout interval to establish the connection, this 681038032Speter option can give the network software time to establish 681138032Speter the link. The default units are seconds. 681238032Speter Move logging of sender information to be as early as possible; 681338032Speter previously, it could be delayed a while for SMTP mail 681438032Speter sent to aliases. Suggested by Brad Knowles of the 681538032Speter Defense Information Systems Agency. 681638032Speter Call res_init() before setting RES_DEBUG; this is required by 681738032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 681838032Speter the National Computer Security Center. 681938032Speter Add xdelay= field in logs -- this is a transaction delay, telling 682038032Speter you how long it took to deliver to this address on the 682138032Speter last try. It is intended to be used for sorting mailing 682238032Speter lists to favor "quick" addresses. Provided for use by 682338032Speter the mailprio scripts (see below). 682438032Speter If a map cannot be opened, and that map is non-optional, and 682538032Speter an address requires that map for resolution, queue the 682638032Speter map instead of bouncing it. This involves creating a 682738032Speter pseudo-class of maps called "bogus-map" -- if a required 682838032Speter map cannot be opened, the class is changed to bogus-map; 682938032Speter all queries against bogus-map return "tempfail". The 683038032Speter bogus-map class is not directly accessible. A sample 683138032Speter implementation was donated by Jem Taylor of Glasgow 683238032Speter University Computing Service. 683338032Speter Fix a possible core dump when mailing to a program that talks 683438032Speter SMTP on its standard input. Fix from Keith Moore of 683538032Speter the University of Kentucky. 683638032Speter Make it possible to resolve filenames to $#local $: @ /filename; 683738032Speter previously, the "@" would cause it to not be recognized 683838032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 683938032Speter Accept a -1 signal to re-exec the daemon. This only works if 684038032Speter argv[0] is a full path to sendmail. 684138032Speter Fix bug in "addr=..." field in O option on little-endian machines 684238032Speter -- the network number wasn't being converted to network 684338032Speter byte order. Patch from Kurt Lidl of Pix Technologies 684438032Speter Corporation. 684538032Speter Pre-initialize the resolver early on; this is to avoid a bug with 684638032Speter BIND 4.9.3 that can cause the _res.retry field to get 684738032Speter reset to zero, causing all name server lookups to time 684838032Speter out. Fix from Matt Day of Artisoft. 684938032Speter Restore T line (trusted users) in config file -- but instead of 685038032Speter locking out the -f flag, they just tell whether or not 685138032Speter an X-Authentication-Warning: will be added. This really 685238032Speter just creates new entries in class 't', so "Ft/file/name" 685338032Speter can be used to read trusted user names from a file. 685438032Speter Trusted users are also allowed to execute programs even 685538032Speter if they have a shell that isn't in /etc/shells. 685638032Speter Improve NEWDB alias file rebuilding so it will create them 685738032Speter properly if they do not already exist. This had been 685838032Speter a MAYBENEXTRELEASE feature in 8.6.9. 685938032Speter Check for @:@ entry in NIS maps before starting up to avoid 686038032Speter (but not prevent, sigh) race conditions. This ought to 686138032Speter be handled properly in ypserv, but isn't. Suggested by 686238032Speter Michael Beirne of Motorola. 686338032Speter Refuse connections if there isn't enough space on the filesystem 686438032Speter holding the queue. Contributed by Robert Dana of Wolf 686538032Speter Communications. 686638032Speter Skip checking for directory permissions in the path to a file 686738032Speter when checking for file permissions iff setreuid() 686838032Speter succeeded -- it is unnecessary in that case. This avoids 686938032Speter significant performance problems when looking for .forward 687038032Speter files. Based on a suggestion by Win Bent of USC. 687138032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 687238032Speter arbitrary ruleset number assigned or "Sname = integer" 687338032Speter to assign a specific ruleset number. Reference is 687438032Speter $>name_or_number. Names can be composed of alphas, digits, 687538032Speter underscore, or hyphen (first character must be non-numeric). 687638032Speter Allow -o flag on AliasFile lines to make the alias file optional. 687738032Speter From Bryan Costales of ICSI. 687838032Speter Add NoRecipientAction option to handle the case where there is 687938032Speter no legal recipient header in the message. It can take 688038032Speter on values: 688138032Speter None Leave the message as is. The 688238032Speter message will be passed on even 688338032Speter though it is in technically 688438032Speter illegal syntax. 688538032Speter Add-To Add a To: header with any 688638032Speter recipients that it can find from 688738032Speter the envelope. This risks exposing 688838032Speter Bcc: recipients. 688938032Speter Add-Apparently-To Add an Apparently-To: header. This 689038032Speter has almost no redeeming social value, 689138032Speter and is provided only for back 689238032Speter compatibility. 689338032Speter Add-To-Undisclosed Add a header reading 689438032Speter To: undisclosed-recipients:; 689538032Speter which will have the effect of 689638032Speter making the message legal without 689738032Speter exposing Bcc: recipients. 689838032Speter Add-Bcc To add an empty Bcc: header. 689938032Speter There is a chance that mailers down 690038032Speter the line will delete this header, 690138032Speter which could cause exposure of Bcc: 690238032Speter recipients. 690338032Speter The default is NoRecipientAction=None. 690438032Speter Truncate (rather than delete) Bcc: lines in the header. This 690538032Speter should prevent later sendmails (at least, those that don't 690638032Speter themselves delete Bcc:) from considering this message to 690738032Speter be non-conforming -- although it does imply that non-blind 690838032Speter recipients can see that a Bcc: was sent, albeit not to whom. 690938032Speter Add SafeFileEnvironment option. If declared, files named as delivery 691038032Speter targets must be regular files in addition to the regular 691138032Speter checks. Also, if the option is non-null then it is used as 691238032Speter the name of a directory that is used as a chroot(2) 691338032Speter environment for the delivery; the file names listed in an 691438032Speter alias or forward should include the name of this root. 691538032Speter For example, if you run with 691638032Speter O SafeFileEnvironment=/arch 691738032Speter then aliases should reference "/arch/rest/of/path". If a 691838032Speter value is given, sendmail also won't try to save to 691938032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 692038032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 692138032Speter Support -A flag for alias files; this will comma concatenate like 692238032Speter entries. For example, given the aliases: 692338032Speter list: member1 692438032Speter list: member2 692538032Speter and an alias file declared as: 692638032Speter OAhash:-A /etc/aliases 692738032Speter the final alias inserted will be "list: member1,member2"; 692838032Speter without -A you will get an error on the second and subsequent 692938032Speter alias for "list". Contributed by Bryan Costales of ICSI. 693038032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 693138032Speter Fix a problem that could cause very long addresses to core dump in 693238032Speter some special circumstances. Problem pointed out by Allan 693338032Speter Johannesen. 693438032Speter (Internal change.) Change interface to expand() (macro expansion) 693538032Speter to be simpler and more consistent. 693638032Speter Delete check for funny qf file names. This didn't really give 693738032Speter any extra security and caused some people some problems. 693838032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 693938032Speter at compile time.) Suggested by Kyle Jones of UUNET. 694038032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 694138032Speter merge with DSN code; this is simpler and more consistent. 694238032Speter This may affect some people who have written their own 694338032Speter checkcompat() routine. 694438032Speter (Internal change.) Eliminate `D' line in qf file. The df file 694538032Speter is now assumed to be the same name as the qf file (with 694638032Speter the `q' changed to a `d', of course). 694738032Speter Avoid forking for delivery if all recipient mailers are marked as 694838032Speter "expensive" -- this can be a major cost on some systems. 694938032Speter Essentially, this forces sendmail into "queue only" mode 695038032Speter if all it is going to do is queue anyway. 695138032Speter Avoid sending a null message in some rather unusual circumstances 695238032Speter (specifically, the RCPT command returns a temporary 695338032Speter failure but the connection is lost before the DATA 695438032Speter command). Fix from Scott Hammond of Secure Computing 695538032Speter Corporation. 695638032Speter Change makesendmail to use a somewhat more rational naming scheme: 695738032Speter Makefiles and obj directories are named $os.$rel.$arch, 695838032Speter where $os is the operating system (e.g., SunOS), $rel is 695938032Speter the release number (e.g., 5.3), and $arch is the machine 696038032Speter architecture (e.g., sun4). Any of these can be omitted, 696138032Speter and anything after the first dot in a release number can 696238032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 696338032Speter version used $os.$arch.$rel and was rather less general. 696438032Speter Change makesendmail to do a "make depend" in the target directory 696538032Speter when it is being created. This involves adding an empty 696638032Speter "depend:" entry in most Makefiles. 696738032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 696838032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 696938032Speter of the Finnish Meteorological Institute. 697038032Speter Fix problem that could cause multiple responses to DATA command 697138032Speter on header syntax errors (e.g., lines beginning with colons). 697238032Speter Problem noted by Jens Thomassen of the University of Oslo. 697338032Speter Don't let null bytes in headers cause truncation of the rest of 697438032Speter the header. 697538032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 697638032Speter Increase timeouts on message data puts to allow time for receivers 697738032Speter to canonify addresses in headers on the fly. This is still 697838032Speter a rather ugly heuristic. From Motonori Nakamura. 697938032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 698038032Speter records are not used when canonifying names, and when MX 698138032Speter lookups are done for addressing they must be fully 698238032Speter qualified. This is useful if you have a wildcard MX record, 698338032Speter although it may cause other problems. In general, don't use 698438032Speter wildcard MX records. Patch from Motonori Nakamura. 698538032Speter Eliminate default two-line SMTP greeting message. Instead of 698638032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 698738032Speter is added between the first and second word of the first 698838032Speter line of the greeting message (i.e., immediately after the 698938032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 699038032Speter compile flag. Old sendmails won't see the ESMTP, but that's 699138032Speter acceptable because SIZE was the only useful extension that 699238032Speter old sendmails understand. 699338032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 699438032Speter invoked state dumps. From Masaharu Onishi. 699538032Speter Allow on-line comments in .forward and :include: files; they are 699638032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 699738032Speter is a space or a tab. This is intended for native 699838032Speter representation of non-ASCII sets such as Japanese, where 699938032Speter existing encodings would be unreadable or would lose 700038032Speter data -- for example, 700138032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 700238032Speter (romanized/less information) 700338032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 700438032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 700538032Speter (with MIME encoding, not human readable) 700638032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 700738032Speter (native encoding with ISO-2022-JP) 700838032Speter The last form is human readable in the Japanese environment. 700938032Speter Based on a fix from (surprise!) Motonori Nakamura. 701038032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 701138032Speter messages to that host; these are most frequently associated 701238032Speter with addresses rather than the host, with the exception of 701338032Speter 421 (service shutting down). The effect was to cause queues 701438032Speter to sometimes take an excessive time to flush. Reported by 701538032Speter Robert Sargent of Southern Geographics Technologies and 701638032Speter Eric Prestemon of American University. 701738032Speter Add Nice=N mailer option to set the niceness at which a mailer will 701838032Speter run. This is actually a relative niceness (that is, an 701938032Speter increment on the background value). 702038032Speter Log queue runs that are skipped due to high loads. They are logged 702138032Speter at LOG_INFO priority iff the log level is > 8. Contributed 702238032Speter by Bruce Nagel of Data General. 702338032Speter Allow the error mailer to accept a DSN-style error status code 702438032Speter instead of an sysexits status code in the host part. 702538032Speter Anything with a dot will be interpreted as a DSN-style code. 702638032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 702738032Speter to encode characters that might be munged by an EBCDIC system 702838032Speter in addition to the set required by RFC 1521. The additional 702938032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 703038032Speter (Think of "IBM 360" as the mnemonic for this flag.) 703138032Speter Change check for mailing to files to look for a pathname of [FILE] 703238032Speter rather than looking for the mailer named *file*. The mapping 703338032Speter of leading slashes still goes to the *file* mailer. This 703438032Speter allows you to implement the *file* mailer as a separate 703538032Speter program, for example, to insert a Content-Length: header 703638032Speter or do special security policy. However, note that the usual 703738032Speter initial checking for the file permissions is still done, and 703838032Speter the program in question needs to be very careful about how 703938032Speter it does the file write to avoid security problems. 704038032Speter Be able to read ~root/.forward even if the path isn't accessible to 704138032Speter regular users. This is disrecommended because sendmail 704238032Speter sometimes does not run as root (e.g., when an unsafe option 704338032Speter is specified on the command line), but should otherwise be 704438032Speter safe because .forward files must be owned by the user for 704538032Speter whom mail is being forwarded, and cannot be a symbolic link. 704638032Speter Suggested by Forrest Aldrich of Wang Laboratories. 704738032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 704838032Speter file. This is used for canonifying hostnames when the 704938032Speter service type is "files". 705038032Speter Implement programs on F (read class from file) line. The syntax is 705138032Speter Fc|/path/to/program to read the output from the program 705238032Speter into class "c". 705338032Speter Probe the network interfaces to find alternate names for this 705438032Speter host. Requires the SIOCGIFCONF ioctl call. Code 705538032Speter contributed by SunSoft. 705638032Speter Add "E" configuration line to set or propagate environment 705738032Speter variables into children. "E<envar>" will propagate 705838032Speter the named variable from the environment when sendmail 705938032Speter was invoked into any children it calls; "E<envar>=<value>" 706038032Speter sets the named variable to the indicated value. Any 706138032Speter variables not explicitly named will not be in the child 706238032Speter environment. However, sendmail still forces an 706338032Speter "AGENT=sendmail" environment variable, in part to enforce 706438032Speter at least one environment variable, since many programs and 706538032Speter libraries die horribly if this is not guaranteed. 706638032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 706738032Speter alias databases -- new algorithm looks for the substring 706838032Speter "/yp/" in the file name. This is more portable and involves 706938032Speter less overhead. Suggested by Motonori Nakamura. 707038032Speter Dynamically allocate the queue work list so that you don't lose 707138032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 707238032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 707338032Speter should not need to be changed) and the MaxQueueRunSize option, 707438032Speter which is the absolute maximum number of jobs that will ever 707538032Speter be handled in a single queue run. Based on code contributed 707638032Speter by Brian Coan of the Institute for Global Communications. 707738032Speter Log message when a message is dropped because it exceeds the maximum 707838032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 707938032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 708038032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 708138032Speter of Mark G. Thomas Consulting. 708238032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 708338032Speter OS-dependent defines). The old semantic of -d0.1 to not 708438032Speter run the daemon in background has been moved to -d99.100, 708538032Speter and the old 52.5 flag (to avoid disconnect() from closing 708638032Speter all output files) has been moved to 52.100. This makes 708738032Speter things more consistent (flags below .100 don't change 708838032Speter semantics) and separates out the backgrounding so that 708938032Speter it doesn't happen automatically on other unrelated debugging 709038032Speter flags. 709138032Speter If -t is used but no addresses are found in the header, give an 709238032Speter error message rather than just doing nothing. Fix from 709338032Speter Motonori Nakamura. 709438032Speter On systems (like SunOS) where the effective gid is not necessarily 709538032Speter included in the group list returned by getgroups(), the 709638032Speter `restrictmailq' option could sometimes cause an authorized 709738032Speter user to not be able to use `mailq'. Fix from Charles Hannum 709838032Speter of MIT. 709938032Speter Allow symbolic service names for [IPC] mailers. Suggested by 710038032Speter Gerry Magennis of Logica International. 710138032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 710238032Speter when running DNS. For example, if the name FTP.Foo.ORG is 710338032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 710438032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 710538032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 710638032Speter This is technically illegal under RFC 822 and 1123, but the 710738032Speter IETF is moving toward legalizing it. Note that turning on 710838032Speter this option is not sufficient to guarantee that a downstream 710938032Speter neighbor won't rewrite the address for you. 711038032Speter Add "-m" flag to makesendmail script -- this tells you what object 711138032Speter directory and Makefile it will use, but doesn't actually do 711238032Speter the make. 711338032Speter Do some additional checking on the contents of the qf file to try 711438032Speter to detect attacks against the qf file. In particular, 711538032Speter abort on any line beginning "From ", and add an "end of 711638032Speter file" line -- any data after that line is prohibited. 711738032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 711838032Speter choices. This can be overridden in the Makefile by using 711938032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 712038032Speter (to the extent that we know it) or by defining 712138032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 712238032Speter sendmail 8 to have more consistent installation instructions. 712338032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 712438032Speter of Sun Microsystems. 712538032Speter Improved symbol table hash function from Eric Wassenaar. This one 712638032Speter is at least 50% faster. 712738032Speter Fix problem that didn't notice that timeout on file open was a 712838032Speter transient error. Fix from Larry Parmelee of Cornell 712938032Speter University. 713038032Speter Allow comments (lines beginning with a `#') in files read for 713138032Speter classes. Suggested by Motonori Nakamura. 713238032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 713338032Speter of dropping out entirely. This makes testing some of the 713438032Speter name server lookups easier to deal with when there are 713538032Speter hung servers. From Motonori Nakamura. 713638032Speter Add new ${opMode} macro that is set to the current operation mode 713738032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 713838032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 713938032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 714038032Speter Kind of like queue-only mode (Odq) except it tries to avoid 714138032Speter any external service requests; for dial-on-demand hosts that 714238032Speter want to minimize DNS lookups when mail is being queued. For 714338032Speter this to work you will also have to make sure that gethostbyname 714438032Speter of your local host name does not do a DNS lookup. 714538032Speter Improved handling of "out of space" conditions from John Myers of 714638032Speter Carnegie Mellon. 714738032Speter Improved security for mailing to files on systems that have fchmod(2) 714838032Speter support. 714938032Speter Improve "cannot send message for N days" message -- now says "could 715038032Speter not send for past N days". Suggested by Tom Moore of AT&T 715138032Speter Global Information Solutions. 715238032Speter Less misleading Subject: line on messages sent to postmaster only. 715338032Speter From Motonori Nakamura. 715438032Speter Avoid duplicate error messages on bad command line flags. From 715538032Speter Motonori Nakamura. 715638032Speter Better error message for case where ruleset 0 falls off the end 715738032Speter or otherwise does not resolve to a canonical triple. 715838032Speter Fix a problem that could cause multiple bounce messages if a bad 715938032Speter address was sent along with a good address to an SMTP 716038032Speter site where that SMTP site returned a 4yz code in response 716138032Speter to the final dot of the data. Problem reported by David 716238032Speter James of British Telecom. 716338032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 716438032Speter from Alexander Dupuy of System Management ARTS. 716538032Speter Delete duplicates in MX lists -- believe it or not, there are sites 716638032Speter that list the same host twice in an MX list. This deletion 716738032Speter only works on adjacent preferences, so an MX list that 716838032Speter had A=5, B=10, A=15 would leave both As, but one that had 716938032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 717038032Speter just in case there is something weird I haven't thought of. 717138032Speter Suggested by Barry Shein of Software Tool & Die. 717238032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 726738032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 726838032Speter University of Brno (Czech Republic). 726938032Speter KSR OS 1.2.2 support from Todd Miller of the University 727038032Speter of Colorado. 727138032Speter UX4800 support from Kazuhisa Shimizu of NEC. 727238032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 727338032Speter in type ``btree'' maps. The semantics of this are undefined 727438032Speter for regular maps, but it can be useful for the user database. 727538032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 727638032Speter lookups while the rebuild is going on. There is a race 727738032Speter condition between the open(... O_TRUNC ...) and the lock 727838032Speter on the file, but it should be quite small. 727938032Speter SMRSH: sendmail restricted shell added to the release. This can 728038032Speter be used as an alternative to /bin/sh for the "prog" mailer, 728138032Speter giving the local administrator more control over what 728238032Speter programs can be run from sendmail. 728338032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 728438032Speter part of the release proper, and isn't fully supported; in 728538032Speter particular, it does not run on System V based systems and 728638032Speter never will. 728738032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 728838032Speter to allow rmail to compile on systems that don't have 728938032Speter function prototypes and systems that don't have snprintf. 729038032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 729138032Speter lists by transaction delay times so that addresses that 729238032Speter respond quickly get sent first. This is to prevent very 729338032Speter sluggish servers from delaying other peoples' mail. 729438032Speter Contributed by Tony Sanders of BSDI. 729538032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 729638032Speter of BSDI. This has a lot of comments to help people out. 729738032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 729838032Speter put this on the m4 command line. On GNU m4 (which 729938032Speter supports the __file__ primitive) you can run m4 in an 730038032Speter arbitrary directory -- use either: 730138032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 730238032Speter or 730338032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 730438032Speter On other versions of m4 that don't support __file__, you 730538032Speter can use: 730638032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 730738032Speter (Note the trailing slash on the _CF_DIR_ definition.) 730838032Speter Old versions of m4 will default to _CF_DIR_=.. for back 730938032Speter compatibility. 731038032Speter CONFIG: fix mail from <> so it will properly convert to 731138032Speter MAILER-DAEMON on local addresses. 731238032Speter CONFIG: fix code that was supposed to catch colons in host 731338032Speter names. Problem noted by John Gardiner Myers of CMU. 731438032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 731538032Speter From Paul Riddle of the University of Maryland, Baltimore 731638032Speter County. 731738032Speter CONFIG: Catch and reject "." as a host address. 731838032Speter CONFIG: Generalize domaintable to look up all domains, not 731938032Speter just unqualified ones. 732038032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 732138032Speter was never used and didn't work anyway. 732238032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 732338032Speter and d on all mailers in the UUCP class. 732438032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 732538032Speter look for an alias for "user+detail", then for "user+*", and 732638032Speter finally for "user". This is intended for forwarding mail 732738032Speter for system aliases such as root and postmaster to a 732838032Speter centralized hub. 732938032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 733038032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 733138032Speter The F=8 flag is also set on the "relay" mailer, since 733238032Speter this is expected to be another sendmail. 733338032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 733438032Speter the name of the UUCP_RELAY -- in some cases, this is the 733538032Speter wrong value (e.g., when we have local UUCP connections), 733638032Speter and this can create unreplyable addresses. From Chip 733738032Speter Rosenthal of Unicom. 733838032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 733964562Sgshapiro Received: header inserted into all messages. Suggested by 734038032Speter Gary Mills of the University of Manitoba. 734138032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 734243730Speter to get the old behavior. I did this upon observing 734338032Speter that almost everyone needed this feature, and that the 734438032Speter concept I was trying to make happen didn't work with 734538032Speter some user agents anyway. FEATURE(notsticky) still works, 734638032Speter but it is a no-op. 734738032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 734838032Speter names are sent, rather than immediately diagnosing them 734938032Speter as User Unknown. 735038032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 735138032Speter and RELAY_MAILER_ARGS to set the arguments for the 735238032Speter indicated mailers. All default to "IPC $h". Patch from 735338032Speter Larry Parmelee of Cornell University. 735438032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 735538032Speter on the client side" and F=P to get an appropriate 735638032Speter return-path. From Kimmo Suominen. 735738032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 735838032Speter as the local mailer. For addresses of the form "user+detail" 735938032Speter the "detail" part is passed to procmail via the -a flag. 736038032Speter Contributed by Kimmo Suominen. 736138032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 736238032Speter use from mailertables. This lets you execute arbitrary 736338032Speter procmail scripts. Contributed by Kimmo Suominen. 736438032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 736538032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 736638032Speter Paul Southworth of CICNet Systems Support. 736738032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 736838032Speter This causes the null return path to be rewritten as 736938032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 737038032Speter From Michael Hohmuth of Technische Universitat Dresden. 737138032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 737238032Speter list us as the best possible MX record to be treated as 737338032Speter though they were local (essentially, assume that they 737438032Speter are included in $=w). This can cause additional DNS 737538032Speter traffic, but is easier to administer if this fits your 737638032Speter local model. It does not work reliably if there are 737738032Speter multiple hosts that share the best MX preference. 737838032Speter Code contributed by John Oleynick of Rutgers. 737938032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 738038032Speter SHell) instead of /bin/sh as the program used for delivery 738138032Speter to programs. If an argument is included, it is used as 738238032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 738338032Speter assumed. 738438032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 738538032Speter size of messages to the local and procmail mailers 738638032Speter respectively. Contributed by Brad Knowles of the Defense 738738032Speter Information Systems Agency. 738838032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 738938032Speter (just like text outside of angle brackets) in order to 739038032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 739138032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 739238032Speter any real systems any more) and tweak the DOMAIN macro 739338032Speter so that it is less likely that users will accidentally use 739438032Speter the Berkeley defaults. Also, create some generic files 739538032Speter that really can be used in the real world. 739638032Speter CONFIG: Add new configuration macros to set character sets for 739738032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 739838032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 739938032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 740038032Speter The old name will still be accepted for a while at least. 740138032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 740238032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 740338032Speter As with all relays, it can be ``mailer:hostname''. Suggested 740438032Speter by Scott Hutton. 740538032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 740638032Speter by Barb Dijker of Labyrinth Computer Services. 740738032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 740838032Speter performance for large alias files, and this confused many 740938032Speter people. 741038032Speter CONFIG: Add confCF_VERSION to append local information to the 741138032Speter configuration version number displayed during SMTP startup. 741238032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 741338032Speter would only work when locally addressed. Fix from 741438032Speter Edvard Tuinder of Cistron Internet Services. 741538032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 741643730Speter "n" (CheckAliases) is set when rebuilding alias database. 741738032Speter Based on code contributed by Claude Marinier. 741838032Speter CONFIG: Allow mailertable to have values of the form 741938032Speter ``error:code message''. The ``code'' is a status code 742038032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 742138032Speter Contributed by David James <dwj@agw.bt.co.uk>. 742238032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 742338032Speter sender domains that will be replaced with the masquerade name. 742438032Speter These domains will not be treated as local, but if mail passes 742538032Speter through with sender addresses in those domains they will be 742638032Speter replaced by the masquerade name. These can also be specified 742738032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 742838032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 742938032Speter as well as the header. Substantial improvements to this 743038032Speter code were contributed by Per Hedeland. 743138032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 743238032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 743338032Speter by Kimmo Suominen. 743438032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 743538032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 743638032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 743738032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 743838032Speter UUCP addressing.

This caused UnixWare 758138032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 758238032Speter Novell Labs Europe. 758338032Speter Fix problem with static linking of local getopt routine when 758438032Speter using GNU's ld command. Fix from John Kennedy of 758538032Speter Cal State Chico. 758638032Speter It was possible to turn off privacy flags. Problem noted by 758738032Speter *Hobbit*. 758838032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 758938032Speter and Liudvikas Bukys. 759038032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 759138032Speter from Spider Boardman. 759238032Speter CONFIG: No changes (version number only, to keep it in sync 759338032Speter with the binaries). 759438032Speter 759564562Sgshapiro8.6.10/8.6.10 1995/02/10 759638032Speter SECURITY: Diagnose bogus values to some command line flags that 759738032Speter could allow trash to get into headers and qf files. 759838032Speter Validate the name of the user returned by the IDENT protocol. 759938032Speter Some systems that really dislike IDENT send intentionally 760038032Speter bogus information. Problem pointed out by Michael Bushnell 760138032Speter of the Free Software Foundation. Has some security 760238032Speter implications. 760338032Speter Fix a problem causing error messages about DNS problems when 760438032Speter the host name contained a percent sign to act oddly 760538032Speter because it was passed as a printf-style format string. 760638032Speter In some cases this could cause core dumps. 760738032Speter Avoid possible buffer overrun in returntosender() if error 760838032Speter message is quite long. From Fletcher Mattox of the 760938032Speter University of Texas. 761038032Speter Fix a problem that would silently drop "too many hops" error 761138032Speter messages if and only if you were sending to an alias. 761238032Speter From Jon Giltner of the University of Colorado and 761338032Speter Dan Harton of Oak Ridge National Laboratory. 761438032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 761538032Speter set and e->e_message was null. Fix from Bruce Nagel of 761638032Speter Data General. 761738032Speter Fix problem that can still cause df files to be left around 761838032Speter after "hop count exceeded" messages. Fix from Andrew 761938032Speter Chang and Shau-Ping Lo of SunSoft. 762038032Speter Fix a problem that can cause buffer overflows on very long 762138032Speter user names (as might occur if you piped to a program 762238032Speter with a lot of arguments). 762338032Speter Avoid returning an error and re-queueing if the host signature 762438032Speter is null; this can occur on addresses like ``user@.''. 762538032Speter Problem noted by Wesley Craig and the University of 762638032Speter Michigan. 762738032Speter Avoid possible calls to malloc(0) if MCI caching is turned 762838032Speter off. Bug fix from Pierre David of the Laboratoire 762938032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 763038032Speter Universite de Versailles - St Quentin, and Jacky 763138032Speter Thibault. 763238032Speter Make a local copy of the line being sent via senttolist() -- in 763338032Speter some cases, buffers could get trashed by map lookups 763438032Speter causing it to do unexpected things. This also simplifies 763538032Speter some of the map code. 763638032Speter CONFIG: No changes (version number only, to keep it in sync 763738032Speter with the binaries). 763838032Speter 763964562Sgshapiro8.6.9/8.6.9 1994/04/19 764038032Speter Do all mail delivery completely disconnected from any terminal. 764138032Speter This provides consistency with daemon delivery and 764238032Speter may have some security implications. 764338032Speter Make sure that malloc doesn't get called with zero size, 764438032Speter since that fails on some systems. Reported by Ed 764538032Speter Hill of the University of Iowa. 764638032Speter Fix multi-line values for $e (SMTP greeting message). Reported 764738032Speter by Mike O'Connor of Ford Motor Company. 764838032Speter Avoid syserr if no NIS domain name is defined, but the map it 764938032Speter is trying to open is optional. From Win Bent of USC. 765038032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 765138032Speter Hesiod support for UDB from Todd Miller of the University of 765238032Speter Colorado. Use "hesiod" as the service name in the U 765338032Speter option. 765438032Speter Fix a problem that failed to set the "authentic" host name (that 765538032Speter is, the one derived from the socket info) if you called 765638032Speter sendmail -bs from inetd. Based on code contributed by 765738032Speter Todd Miller (this problem was also reported by Guy Helmer 765838032Speter of Dakota State University). This also fixes a related 765938032Speter problem reported by Liudvikas Bukys of the University of 766038032Speter Rochester. 766138032Speter Parameterize "nroff -h" in all the Makefiles so people with 766238032Speter variant versions can use them easily. Suggested by 766338032Speter Peter Collinson of Hillside Systems. 766438032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 766538032Speter spaces between parameters instead of one. Reported by 766638032Speter Valdis Kletnieks of Virginia Tech. 766738032Speter Reduce the number of system calls during message collection by 766838032Speter using global timeouts around the collect() loop. This 766938032Speter code was contributed by Eric Wassenaar. 767038032Speter If the initial hostname name gathering results in a name 767138032Speter without a dot (usually caused by NIS misconfiguration) 767238032Speter and BIND is compiled in, directly access DNS to get 767338032Speter the canonical name. This should make life easier for 767438032Speter Solaris systems. If it still can't be resolved, and 767538032Speter if the name server is listed as "required", try again 767638032Speter in 30 seconds. If that also fails, exit immediately to 767738032Speter avoid bogus "config error: mail loops back to myself" 767838032Speter messages. 767938032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 768038032Speter message to explain how much space was available and 768138032Speter sound a bit less threatening. Suggested by Stan Janet 768238032Speter of the National Institute of Standards and Technology. 768338032Speter If mail is delivered to an alias that has an owner, deliver any 768438032Speter requested return-receipt immediately, and strip the 768538032Speter Return-Receipt-To: header from the subsequent message. 768638032Speter This prevents a certain class of denial of service 768738032Speter attack, arguably gives more reasonable semantics, and 768838032Speter moves things more towards what will probably become a 768938032Speter network standard. Suggested by Christopher Davis of 769038032Speter Kapor Enterprises. 769138032Speter Add a "noreceipts" privacy flag to turn off all return receipts 769238032Speter without recompiling. 769338032Speter Avoid printing ESMTP parameters as part of the error message 769438032Speter if there are errors during parsing. This change is 769538032Speter purely cosmetic. 769638032Speter Avoid sending out error messages during the collect phase of 769738032Speter SMTP; there is an MVS mailer from UCLA that gets 769838032Speter confused by this. Of course, I think it's their bug.... 769938032Speter Check for the $j macro getting undefined, losing a dot, or getting 770038032Speter lost from $=w in the daemon before accepting a connection; 770138032Speter if it is, it dumps state, prints a LOG_ALERT message, 770238032Speter and drops core for debugging. This is an attempt to 770338032Speter track down a bug that I thought was long since gone. 770438032Speter If you see this, please forward the log fragment to 770538032Speter sendmail@sendmail.ORG. 770638032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 770738032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 770838032Speter Wolfhugel. 770938032Speter Instead of trying to truncate the listen queue for the server 771038032Speter SMTP port when the load average is too high, just close 771138032Speter the port completely and reopen it later as needed. 771238032Speter This ensures that the other end gets a quick "connection 771338032Speter refused" response, and that the connection can be 771438032Speter recovered later. In particular, some socket emulations 771538032Speter seem to get confused if you tweak the listen queue 771638032Speter size around and can never start listening to connections 771738032Speter again. The down side is that someone could start up 771838032Speter another daemon process in the interim, so you could 771938032Speter have multiple daemons all not listening to connections; 772038032Speter this could in turn cause the sendmail.pid file to be 772138032Speter incorrect. A better approach might be to accept the 772238032Speter connection and give a 421 code, but that could break 772343730Speter other mailers in mysterious ways and have paging behavior 772438032Speter implications. 772538032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 772638032Speter set debugging on the wrong socket. From Eric Wassenaar. 772738032Speter When creating a df* temporary file, be sure you truncate any 772838032Speter existing data in the file -- otherwise system crashes 772938032Speter and the like could result in extra data being sent. 773038032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 773138032Speter doc directory. This includes some additional 773238032Speter information. 773338032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 773438032Speter of recipient envelope addresses. This should have been 773538032Speter handled by the $&h trick, but broke if people were 773638032Speter mixing domainized and UUCP addresses. They should 773738032Speter probably have converted all the way over to uucp-uudom 773838032Speter instead of uucp-{new,old}, but the failure mode was to 773938032Speter loop the mail, which was bad news. 774038032Speter Portability fixes: 774138032Speter Newer BSDI systems (several people). 774238032Speter Older BSDI systems from Christophe Wolfhugel. 774338032Speter Intergraph CLIX, from Paul Southworth of CICNet. 774438032Speter UnixWare, from Evan Champion. 774538032Speter NetBSD from Adam Glass. 774638032Speter Solaris from Quentin Campbell of the University of 774738032Speter Newcastle upon Tyne. 774838032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 774938032Speter Corporation. 775038032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 775138032Speter SunOS (it has setsid() and setvbuf() calls) from 775238032Speter Jonathan Kamens of OpenVision Technologies. 775338032Speter HP-UX from Tor Lillqvist. 775438032Speter New Files: 775538032Speter src/Makefile.CLIX 775638032Speter src/Makefile.NCR3000 775738032Speter doc/changes/Makefile 775838032Speter doc/changes/changes.me 775938032Speter doc/changes/changes.ps 776038032Speter 776164562Sgshapiro8.6.8/8.6.6 1994/03/21 776238032Speter SECURITY: it was possible to read any file as root using the 776338032Speter E (error message) option. Reported by Richard Jones; 776438032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 776538032Speter 776664562Sgshapiro8.6.7/8.6.6 1994/03/14 776738032Speter SECURITY: it was possible to get root access by using weird 776838032Speter values to the -d flag. Thanks to Alain Durand of 776938032Speter INRIA for forwarding me the notice from the bugtraq 777038032Speter list. 777138032Speter 777264562Sgshapiro8.6.6/8.6.6 1994/03/13 777338032Speter SECURITY: the ability to give files away on System V-based 777438032Speter systems proved dangerous -- don't run as the owner 777538032Speter of a :include: file on a system that allows giveaways. 777638032Speter Unfortunately, this also applies to determining a 777738032Speter valid shell. 777838032Speter IMPORTANT: Previous versions weren't expiring old connections 777938032Speter in the connection cache for a long time under some 778038032Speter circumstances. This could result in resource exhaustion, 778138032Speter both at your end and at the other end. This checks the 778238032Speter connections for timeouts much more frequently. From 778338032Speter Doug Anderson of NCSC. 778438032Speter Fix a glitch that snuck in that caused programs to be run as 778538032Speter the sender instead of the recipient if the mail was 778638032Speter from a local user to another local user. From 778738032Speter Motonori Nakamura of Kyoto University. 778838032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 778938032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 779038032Speter Bryan Costales of ICSI. 779138032Speter Change the method used to declare the "statfs" availability; 779238032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 779338032Speter tweaking in conf.c, there is a single #define called 779438032Speter SFS_TYPE which takes on one of six values (SFS_NONE 779538032Speter for no statfs availability, SFS_USTAT for the ustat(2) 779638032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 779738032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 779838032Speter statfs(2) call with the declarations in <sys/vfs.h>, 779938032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 780038032Speter Fix glitch in NetInfo support that could return garbage if 780138032Speter there was no "/locations/sendmail" property. From 780238032Speter David Meyer of the University of Virginia. 780338032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 780438032Speter to allow Linux to turn it off even though it is a 780538032Speter BSD-like system. 780638032Speter Allow setting of "ident" timeout to zero to turn off the ident 780738032Speter protocol entirely. 780838032Speter Make 7-bit stripping local to a connection (instead of to a 780938032Speter mailer); this allows you to specify that SMTP is a 781038032Speter 7-bit channel, but revert to 8-bit should it advertise 781138032Speter that it supports 8BITMIME. You still have to specify 781238032Speter mailer flag 7 to get this stripping at all. 781338032Speter Improve makesendmail script so it handles more cases automatically. 781438032Speter Tighten up restrictions on taking ownership of :include: files 781538032Speter to avoid problems on systems that allow you to give away 781638032Speter files. 781738032Speter Fix a problem that made it impossible to rebuild the alias 781838032Speter file if it was on a read-only file system. From 781938032Speter Harry Edmon of the University of Washington. 782038032Speter Improve MX randomization function. From John Gardiner Myers 782138032Speter of CMU. 782238032Speter Fix a minor glitch causing a bogus message to be printed (used 782338032Speter %s instead of %d in a printf string for the line number) 782438032Speter when a bad queue file was read. From Harry Edmon. 782538032Speter Allow $s to remain NULL on locally generated mail. I'm not 782638032Speter sure this is necessary, but a lot of people have complained 782738032Speter about it, and there is a legitimate question as to whether 782838032Speter "localhost" is legal as an 822-style domain. 782938032Speter Fix a problem with very short line lengths (mailer L= flag) in 783038032Speter headers. This causes a leading space to be added onto 783138032Speter continuation lines (including in the body!), and also 783238032Speter tries to wrap headers containing addresses (From:, To:, 783338032Speter etc) intelligently at the shorter line lengths. Problem 783438032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 783538032Speter Log the real user name when logging syserrs, since these can have 783638032Speter security implications. Suggested by several people. 783738032Speter Fix address logging of cached connections -- it used to always 783838032Speter log the numeric address as zero. This is a somewhat 783938032Speter bogus implementation in that it does an extra system 784038032Speter call, but it should be an inexpensive one. Fix from 784138032Speter Motonori Nakamura. 784238032Speter Tighten up handling of short syslog buffers even more -- there 784338032Speter were cases where the outgoing relay= name was too long 784438032Speter to share a line with delay= and mailer= logging. 784538032Speter Limit the overhead on split envelopes to one open file descriptor 784638032Speter per envelope -- previously the overhead was three 784738032Speter descriptors. This was in response to a problem reported 784838032Speter by P{r (Pell) Emanuelsson. 784938032Speter Fixes to better handle the case of unexpected connection closes; 785038032Speter this redirects the output to the transcript so the info 785138032Speter is not lost. From Eric Wassenaar. 785238032Speter Fix potential string overrun if you macro evaluate a string that 785338032Speter has a naked $ at the end. Problem noted by James Matheson 785438032Speter <jmrm@eng.cam.ac.uk>. 785538032Speter Make default error number on $#error messages 553 (``Requested 785638032Speter action not taken: mailbox name not allowed'') instead of 785738032Speter 501 (``Syntax error in parameters or arguments'') to 785838032Speter avoid bogus "protocol error" messages. 785938032Speter Strip off any existing trailing dot on names during $[ ... $] 786038032Speter lookup. This prevents it from ending up with two dots 786138032Speter on the end of dot terminated names. From Wesley Craig 786238032Speter of the University of Michigan and Bryan Costales of ICSI. 786338032Speter Clean up file class reading so that the debugging information is 786438032Speter more informative. It hadn't been using setclass, so you 786538032Speter didn't see the class items being added. 786638032Speter Avoid core dump if you are running a version of sendmail where 786738032Speter NIS is compiled in, and you specify an NIS map, but 786838032Speter NIS is not running. Fix from John Oleynick of 786938032Speter Rutgers. 787038032Speter Diagnose bizarre case where res_search returns a failure value, 787138032Speter but sets h_errno to a success value. 787238032Speter Make sure that "too many hops" messages are considered important 787338032Speter enough to send an error to the Postmaster (that is, the 787438032Speter address specified in the P option). This fix should 787538032Speter help problems that cause the df file to be left around 787638032Speter sometimes -- unfortunately, I can't seem to reproduce 787738032Speter the problem myself. 787838032Speter Avoid core dump (null pointer reference) on EXPN command; this 787938032Speter only occurred if your log level was set to 10 or higher 788038032Speter and the target account was an alias or had a .forward file. 788138032Speter Problem noted by Janne Himanka. 788238032Speter Avoid "denial of service" attacks by someone who is flooding your 788338032Speter SMTP port with bad commands by shutting the connection 788438032Speter after 25 bad commands are issued. From Kyle Jones of 788538032Speter UUNET. 788638032Speter Fix core dump on error messages with very long "to" buffers; 788738032Speter fmtmsg overflows the message buffer. Fixed by trimming 788838032Speter the to address to 203 characters. Problem reported by 788938032Speter John Oleynick. 789038032Speter Fix configuration for HASFLOCK -- there were some spots where 789138032Speter a #ifndef was incorrectly #ifdef. Pointed out by 789238032Speter George Baltz of the University of Maryland. 789338032Speter Fix a typo in savemail() that could cause the error message To: 789438032Speter lists to be incorrect in some places. From Motonori 789538032Speter Nakamura. 789638032Speter Fix a glitch that can cause duplicate error messages on split 789738032Speter envelopes where an address on one of the lists has a 789838032Speter name server failure. Fix from Voradesh Yenbut of the 789938032Speter University of Washington. 790038032Speter Fix possible bogus pointer reference on ESMTP parameters that 790138032Speter don't have an ``=value'' part. 790238032Speter CNAME loops caused an error message to be generated, but also 790338032Speter re-queued the message. Changed to just re-queue the 790438032Speter message (it's really hard to just bounce it because 790538032Speter of the weird way the name server works in the presence 790638032Speter of CNAME loops). Problem noted by James M.R.Matheson 790738032Speter of Cambridge University. 790838032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 790938032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 791038032Speter user name. Suggested by Andreas Stolcke of ICSI. 791138032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 791238032Speter override it easily in the Makefile -- that is, you can 791338032Speter turn it off using -DNAMED_BIND=0. 791438032Speter If a gethostbyname(...) of an address with a trailing dot fails, 791538032Speter try it without the trailing dot. This is because if 791638032Speter you have a version of gethostbyname() that falls back 791738032Speter to NIS or the /etc/hosts file it will fail to find 791838032Speter perfectly reasonable names that just don't happen to 791938032Speter be dot terminated in the hosts file. You don't want to 792038032Speter strip the dot first though because we're trying to ensure 792138032Speter that country names that match one of your subdomains get 792238032Speter a chance. 792338032Speter PRALIASES: fix bogus output on non-null-terminated strings. 792438032Speter From Bill Gianopoulos of Raytheon. 792538032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 792638032Speter This was in code intended to only catch the self-literal 792738032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 792838032Speter IP address), but the code was broken. However, it will 792938032Speter still do this if $M is defined; this is necessary to 793038032Speter get client configurations to work (sigh). Note that this 793138032Speter means that $M overrides :mailname entries in the user 793238032Speter database! Problem noted by Paul Southworth. 793338032Speter CONFIG: Fix definition of Solaris help file location. From 793438032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 793538032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 793638032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 793738032Speter and USENET_MAILER_MAX to tweak the maximum message 793838032Speter size for various mailers. 793938032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 794038032Speter instead of assuming that it is "inews" for consistency 794138032Speter with other mailers. From Michael Corrigan of UC San Diego. 794238032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 794338032Speter qualify the address in the SMTP envelope as user@{relay|hub} 794438032Speter instead of user@$j. From Bill Wisner of The Well. 794538032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 794638032Speter CONFIG: Don't turn off case mapping of user names in the local 794738032Speter mailer for IRIX. This was different than most every other 794838032Speter system. 794938032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 795038032Speter envelope. Noted by Thierry Besancon 795138032Speter <besancon@excalibur.ens.fr>. 795238032Speter CONFIG: Don't include -z by default on uux line -- most systems 795338032Speter don't want it set by default. Pointed out by Philippe 795438032Speter Michel of Thomson CSF. 795538032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 795638032Speter host name was foo.bar.ray.com and you matched against 795738032Speter ".ray.com", the old implementation bound %1 to "bar" 795838032Speter instead of "foo.bar". Also, allow "." in the mailertable 795938032Speter to match anything -- essentially, take over SMART_HOST. 796038032Speter This also moves matching of explicit local host names 796138032Speter before the mailertable so they don't have to be special 796238032Speter cased in the mailertable data. Reported by Bill 796338032Speter Gianopoulos of Raytheon; the fix for the %1 binding 796438032Speter problem was contributed by Nicholas Comanos of the 796538032Speter University of Sydney. 796638032Speter CONFIG: Don't include "root" in class $=L (users to deliver 796738032Speter locally, even if a hub or relay exists) by default. 796838032Speter This is because of the known bug where definition of 796938032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 797038032Speter both and deliver into the local mailbox. 797138032Speter CONFIG: Move up bitdomain and uudomain handling so that they 797238032Speter are done before .UUCP class matching; uudomain was 797338032Speter reported as ineffective before. This also frees up 797438032Speter diversion 8 for future use. Problem reported by Kimmo 797538032Speter Suominen. 797638032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 797738032Speter into host names. As pointed out by Jonathan Kamens, 797838032Speter these are often used because either the forward or reverse 797938032Speter mapping is broken; this translation makes it broken again. 798038032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 798138032Speter Suominen. 798238032Speter Portability fixes: 798338032Speter Unicos from David L.

From 800738032Speter Bob Campbell at U.C. Berkeley. 800838032Speter Security fix: group ids were not completely set when programs 800938032Speter were invoked. This caused programs to have group 801038032Speter permissions they should not have had (usually group 801138032Speter daemon instead of their own group). In particular, 801238032Speter Perl scripts would refuse to run. 801338032Speter Security: check to make sure files that are written are not 801438032Speter symbolic links (at least under some circumstances). 801538032Speter Although this does not respond to a specific known 801638032Speter attack, it's just a good idea. Suggested by 801738032Speter Christian Wettergren. 801838032Speter Security fix: if a user had an NFS mounted home directory on 801938032Speter a system with a restricted shell listed in their 802038032Speter /etc/passwd entry, they could still execute any 802138032Speter program by putting that in their .forward file. 802238032Speter This fix prevents that by insisting that their shell 802338032Speter appear in /etc/shells before allowing a .forward to 802438032Speter execute a program or write a file. You can disable 802538032Speter this by putting "*" in /etc/shells. It also won't 802638032Speter permit world-writable :include: files to reference 802738032Speter programs or files (there's no way to disable this). 802843730Speter These behaviors are only one level deep -- for 802938032Speter example, it is legal for a world-writable :include: 803038032Speter file to reference an alias that writes a file, on 803138032Speter the assumption that the alias file is well controlled. 803238032Speter Security fix: root was not treated suspiciously enough when 803338032Speter looking into subdirectories. This would potentially 803438032Speter allow a cracker to examine files that were publicly 803538032Speter readable but in a non-publicly searchable directory. 803638032Speter Fix a problem that causes an error on QUIT on a cached 803738032Speter connection to create problems on the current job. 803838032Speter These are typically unrelated, so errors occur in 803938032Speter the wrong place. 804038032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 804138032Speter runs more responsive to load average, and fixes a 804238032Speter problem that ignored the load average in locally 804338032Speter generated mail. From Eric Wassenaar. 804438032Speter Fix possible core dump on aliases with null LHS. From 804538032Speter John Orthoefer of BB&N. 804638032Speter Revert to using flock() whenever possible -- there are just 804738032Speter too many bugs in fcntl() locking, particularly over 804838032Speter NFS, that cause sendmail to fail in perverse ways. 804938032Speter Fix a bug that causes the connection cache to get confused 805038032Speter when sending error messages. This resulted in 805138032Speter "unexpected close" messages. It should fix itself 805238032Speter on the following queue run. Problem noted by 805338032Speter Liudvikas Bukys of the University of Rochester. 805438032Speter Include $k in $=k as documented in the Install & Op Guide. 805538032Speter This seems odd, but it was documented.... From 805638032Speter Michael Corrigan of UCSD. 805738032Speter Fix problem that caused :include:s from alias files to be 805838032Speter forced to be owned by root instead of daemon 805938032Speter (actually DefUid). From Tim Irvin. 806038032Speter Diagnose unrecognized I option values -- from Mortin Forssen 806138032Speter of the Chalmers University of Technology. 806238032Speter Make "error" mailer work consistently when there is no error 806338032Speter code associated with it -- previously it returned OK 806438032Speter even though there was a real problem. Now it assumes 806538032Speter EX_UNAVAILABLE. 806638032Speter Fix bug that caused the last header line of messages that had 806738032Speter no body and which were terminated with EOF instead of 806838032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 806938032Speter Fix core dump on SMTP mail to programs that failed -- it tried 807038032Speter to go to a "next MX host" when none existed, causing 807138032Speter a core dump. From der Mouse at McGill University. 807238032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 807338032Speter this makes it easier to turn it off (using 807438032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 807538032Speter Fix YP_MASTER_NAME store to use the unupdated result of 807638032Speter gethostname() (instead of myhostname(), which tries 807738032Speter to fully qualify the name) to be consistent with 807838032Speter SunOS. If your hostname is unqualified, this fixes 807938032Speter transfers to slave servers. Bug noted by Keith 808038032Speter McMillan of Ameritech Services, Inc. 808138032Speter Fix Ultrix problem: gethostbyname() can return a very large 808238032Speter (> 500) h_length field, which causes the sockaddr 808338032Speter to be trashed. Use the size of the sockaddr instead. 808438032Speter Fix from Bob Manson of Ohio State. 808538032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 808638032Speter defined -- this confuses gethostbyname on hosts 808738032Speter file lookups, which doesn't understand the trailing 808838032Speter dot convention. 808938032Speter Log SMTP server subprocesses that die with a signal instead 809038032Speter of from a clean exit. 809138032Speter If you don't have option "I" set, don't assume that a DNS 809238032Speter "host unknown" message is authoritative -- it 809338032Speter might still be found in /etc/hosts. 809438032Speter Fix a problem that would cause Deferred: messages to be sent 809538032Speter as the subject of an error message, even though the 809638032Speter actual cause of a message was more severe than that. 809738032Speter Problem noted by Chris Seabrook of OSSI. 809838032Speter Fix race condition in DBM alias file locking. From Kyle 809938032Speter Jones of UUNET. 810038032Speter Limit delivery syslog line length to avoid bugs in some 810138032Speter versions of syslog(3). This adds a new compile time 810238032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 810338032Speter University, which is in turn derived from IDA. 810438032Speter Fix quotes inside of comments in addresses -- previously 810538032Speter it insisted that they be balanced, but the 822 spec 810638032Speter says that they should be ignored. 810738032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 810838032Speter debugging). This also evaluates ruleset 89, if set 810938032Speter (with the null input), and logs the result. This 811038032Speter should be used sparingly, since the rewrite process 811138032Speter is not reentrant. 811238032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 811338032Speter documented in the Bat Book. 811438032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 811538032Speter return an error message and did not requeue the message. 811638032Speter Fix based on code from Roland Dirlewanger of 811738032Speter Reseau Regional Aquarel, Bordeaux, France. 811838032Speter Fix a problem that caused a seg fault if you got a 421 error 811938032Speter code during some parts of connection initialization. 812038032Speter I've only seen this when talking to buggy mailers on 812138032Speter the other end, but it shouldn't give a seg fault in 812238032Speter any case. From Amir Plivatsky. 812338032Speter Fix core dump caused by a ruleset call that returns null. 812438032Speter Fix from Bryan Costales of ICSI. 812538032Speter Full-Name: field was being ignored.

Suggested by 813238032Speter Bryan Costales. 813338032Speter Initialize non-alias maps during alias rebuilds -- they may be 813438032Speter needed for parsing. Problem noted by Douglas Anderson. 813538032Speter Log sender address even if no message was collected in SMTP 813638032Speter (e.g., if all RCPTs failed). Suggested by Motonori 813738032Speter Nakamura. 813838032Speter Don't reflect the owner-list contents into the envelope sender 813938032Speter address if the value contains ", :, /, or | (to avoid 814038032Speter illegal addresses appearing there). 814138032Speter Efficiency hack for toktype macro -- from Craig Partridge of 814238032Speter BB&N. 814338032Speter Clean up DNS error printing so that a host name is always 814438032Speter included. 814538032Speter Remember to set $i during queue runs. Reported by Stephen 814638032Speter Campbell of Dartmouth University. 814738032Speter If the environment variable HOSTALIASES is set, use it during 814838032Speter canonification as the name of a file with per-user host 814938032Speter translations so that headers are properly mapped.

From Vince 815938032Speter DeMarco. 816038032Speter Fix a glitch that sometimes caused :include:s that pointed to 816138032Speter NFS filesystems that were down to give an "aliasing/ 816238032Speter forwarding loop broken" message instead of queueing 816338032Speter the message for retry. Noted by William C Fenner of 816438032Speter the NRL Connection Machine Facility. 816538032Speter Fix a problem that could cause a core dump if the input sequence 816638032Speter had (or somehow acquired) a \231 character. 816738032Speter Make sure that route-addrs always have <angle brackets> around 816838032Speter them in non-SMTP envelopes (SMTP envelopes already do 816938032Speter this properly). 817038032Speter Avoid weird headers on unbalanced punctuation of the form: 817138032Speter ``Joe User <user)'' -- this caused reference to the 817238032Speter null macro. Fix from Rick McCarty of IO.COM. 817338032Speter Fix a problem that caused an alias "user: user@local.host" to 817438032Speter not have the QNOTREMOTE bit set; this caused configs 817538032Speter to act as if FEATURE(notsticky) was defined even when 817638032Speter it was not. The effect of the problem was to make it 817738032Speter very hard to to set up satellite sites that had a few 817838032Speter local accounts, with everything else forwarded to a 817938032Speter corporate hub. Reported by Detlef Drewanz of the 818038032Speter University of Rostock and Mark Frost of NCD. 818138032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 818238032Speter addresses. This is more efficient (fewer name server 818338032Speter calls) and fixes certain unusual configurations, such 818438032Speter as those that have ruleset 4 do something that is 818538032Speter non-idempotent unless a mailer-specific ruleset did 818638032Speter something else. Problem reported by Brian J. Coan 818738032Speter of the Institute for Global Communications. 818838032Speter Fix the "obsolete argument" routine in main to better understand 818938032Speter new arguments.

Briefly, if you are sending to host 825538032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 825638032Speter "foo!baz" remains "foo!baz", and anything else has 825738032Speter the local name prepended. 825838032Speter CONFIG: portability fixes for HP-UX. 825938032Speter DOC: several minor problems fixed in the Install & Op Guide. 826038032Speter MAKEMAP: fix core dump problem on lines that are too long or 826138032Speter which lack newline. From Mark Delany. 826238032Speter MAILSTATS: print sums of columns (total messages & kbytes 826338032Speter in and out of the system). From Tom Ferrin of UC 826438032Speter San Francisco Computer Graphics Lab. 826538032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 826638032Speter On HP-UX, /etc/sendmail.cf has been moved to 826738032Speter /usr/lib/sendmail.cf to match HP sendmail. 826838032Speter Permissions have been tightened up on world-writable 826938032Speter :include: files and accounts that have shells 827038032Speter that are not listed in /etc/shells. This may 827138032Speter cause some .forward files that have worked 827238032Speter before to start failing. 827338032Speter SIGUSR1 dumps some state to the log. 827438032Speter NEW FILES: 827538032Speter src/Makefile.DGUX 827638032Speter src/Makefile.Dynix 827738032Speter src/Makefile.FreeBSD 827838032Speter src/Makefile.Mach386 827938032Speter src/Makefile.NetBSD 828038032Speter src/Makefile.RISCos 828138032Speter src/Makefile.SCO 828238032Speter src/Makefile.SVR4 828338032Speter src/Makefile.Titan 828438032Speter cf/mailer/pop.m4 828538032Speter cf/ostype/bsdi1.0.m4 828638032Speter cf/ostype/dgux.m4 828738032Speter cf/ostype/dynix3.2.m4 828838032Speter cf/ostype/sco3.2.m4 828938032Speter makemap/Makefile.dist 829038032Speter praliases/Makefile.dist 829138032Speter 829264562Sgshapiro8.6.4/8.6.4 1993/10/31 829338032Speter Repair core-dump problem (write to read-only memory segment) 829438032Speter if you fall back to the return-to-Postmaster case in 829538032Speter savemail. Problem reported by Richard Liu. 829638032Speter Immediately diagnose bogus sender addresses in SMTP. This 829738032Speter makes quite certain that crackers can't use this 829838032Speter class of attack. 829938032Speter Reliability Fix: check return value from fclose() and fsync() 830038032Speter in a few critical places. 830138032Speter Minor problem in initsys() that reversed a condition for 830238032Speter redirecting the output channel on queue runs. It's 830338032Speter not clear this code even does anything. From Eric 830438032Speter Wassenaar of the Dutch National Institute for Nuclear 830538032Speter and High-Energy Physics. 830638032Speter Fix some problems that caused queue runs to do "too much work", 830738032Speter such as double-reading the Errors-To: header. From 830838032Speter Eric Wassenaar. 830938032Speter Error messages on writing the temporary file (including the 831038032Speter data file) were getting suppressed in SMTP -- this 831138032Speter fix causes them to be properly reported. From Eric 831238032Speter Wassenaar. 831338032Speter Some changes to support AF_UNIX sockets -- this will only 831438032Speter really become relevant in the next release, but some 831538032Speter people need it for local patches. From Michael 831638032Speter Corrigan of UC San Diego. 831738032Speter Use dynamically allocated memory (instead of static buffers) 831838032Speter for macros defined in initsys() and settime(); since 831938032Speter these can have different values depending on which 832038032Speter envelope they are in. From Eric Wassenaar. 832138032Speter Improve logging to show ctladdr on to= logging; this tells you 832238032Speter what uid/gid processes ran as. 832338032Speter Fix a problem that caused error messages to be discarded if 832438032Speter the sender address was unparseable for some reason; 832538032Speter this was supposed to fall back to the "return to 832638032Speter postmaster" case. 832738032Speter Improve aliaswait backoff algorithm. 832838032Speter Portability patches for Linux (8.6.3 required another header 832938032Speter file) (from Karl London) and SCO UNIX. 833038032Speter CONFIG: patch prog mailer to not strip host name off of envelope 833138032Speter addresses (so that it matches local again). From 833238032Speter Christopher Davis. 833338032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 833438032Speter this prevents uux from seeing lines with null names like 833538032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 833638032Speter Nakamura of Kyoto University. 833738032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 833838032Speter it shouldn't fail miserably. From Motonori Nakamura. 833938032Speter 834064562Sgshapiro8.6.2/8.6.2 1993/10/15 834138032Speter Put a "successful delivery" message in the transcript for 834238032Speter addresses that get return-receipts. 834338032Speter Put a prominent "this is only a warning" message in warning 834438032Speter messages -- some people don't read carefully enough 834538032Speter and end up sending the message several times. 834638032Speter Include reason for temporary failure in the "warning" return 834738032Speter message. Currently, it just says "cannot send for 834838032Speter four hours". 834938032Speter Fix the "Original message received" time generated for 835038032Speter returntosender messages. It was previously listed as 835138032Speter the current time. Bug reported by Eric Hagberg of 835238032Speter Cornell University Medical College. 835338032Speter If there is an error when writing the body of a message, 835438032Speter don't send the trailing dot and wait for a response 835538032Speter in sender SMTP, as this could cause the connection to 835638032Speter hang up under some bizarre circumstances. From Eric 835738032Speter Wassenaar. 835838032Speter Fix some server SMTP synchronization problems caused when 835938032Speter connections fail during message collection. From 836038032Speter Eric Wassenaar. 836138032Speter Fix a problem that can cause srvrsmtp to reject mail if the 836238032Speter name server is down -- it accepts the RCPT but rejects 836338032Speter the DATA command. Problem reported by Jim Murray of 836438032Speter Stratus. 836538032Speter Fix a problem that can cause core dumps if the config file 836638032Speter incorrectly resolves to a null hostname. Reported by 836738032Speter Allan Johannesen of WPI. 836838032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 836938032Speter by non-root users were not put into 837038032Speter X-Authentication-Warning:s as intended because the 837143730Speter config file hadn't set the PrivacyOptions yet. Fix 837238032Speter from Sven-Ove Westberg of the University of Lulea. 837338032Speter Under very odd circumstances, the alias file rebuild code 837438032Speter could get confused as to whether a database was 837538032Speter open or not. 837638032Speter Check "vendor code" on the end of V lines -- this is 837738032Speter intended to provide a hook for vendor-specific 837838032Speter configuration syntax. (This is a "new feature", 837938032Speter but I've made an exception to my rule in a belief 838038032Speter that this is a highly exceptional case.) 838138032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 838238032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 838338032Speter (from Jon Forrest of UC Berkeley) 838438032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 838538032Speter 838664562Sgshapiro8.6.1/8.6 1993/10/08 838738032Speter Portability fixes for A/UX and Encore UMAX V. 838838032Speter Fix error message handling -- if you had a name server down 838938032Speter causing an error during parsing, that message was never 839038032Speter propagated to the queue file. 839138032Speter 839264562Sgshapiro8.6/8.6 1993/10/05 839338032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 839438032Speter conf.h (other systems have the same bug). 839538032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 839638032Speter getdtablesize() instead of sysconf(); a disturbingly 839738032Speter large number of systems defined _SC_OPEN_MAX in the 839838032Speter header files but don't have the syscall. 839938032Speter Another patch to really truly ignore MX records in getcanonname 840038032Speter if trymx == FALSE. 840138032Speter Fix problem that caused the "250 IAA25499 Message accepted for 840238032Speter delivery" message to be omitted if there was an error 840338032Speter in the header of the message (e.g., a bad Errors-To: 840438032Speter line). Pointed out by Michael Corrigan of UCSD. 840538032Speter Announce name of host we are chatting when we get errors; this 840638032Speter is an IDA-ism suggested by Christophe Wolfhugel. 840738032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 840838032Speter Australian Artificial Intelligence Institute), SCO Unix 840938032Speter (from Murray Kucherawy of Hookup Communication Corp.), 841038032Speter NeXT (from Vince DeMarco and myself), Linux (from 841138032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 841238032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 841338032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 841438032Speter Some changes to get around gcc optimizer bugs. From Takahiro 841538032Speter Kanbe. 841638032Speter Fix error recovery in queueup if another tf file of the same 841738032Speter name already exists. Problem stumbled over by Bill 841838032Speter Wisner of The Well. 841938032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 842038032Speter Problem noted by Keith McMillan of Ameritech Services. 842138032Speter Deal with group permissions properly when opening .forward and 842238032Speter :include: files. This relaxes the 8.1C restrictions 842338032Speter slightly more. This includes proper setting of groups 842438032Speter when reading :include: files, allowing you to read some 842538032Speter files that you should be able to read but have previously 842638032Speter been denied unless you owned them or they had "other" 842738032Speter read permission. 842838032Speter Make certain that $j is in $=w (after the .cf is read) so that 842938032Speter if the user is forced to override some silly system, 843038032Speter MX suppression will still work. 843138032Speter Fix a couple of efficiency problems where newstr was double- 843238032Speter calling expensive routines. In at least one case, it 843338032Speter wasn't guaranteed that they would always return the 843438032Speter same result. Problem noted by Christophe Wolfhugel. 843538032Speter Fix null pointer dereference in putoutmsg -- only on an error 843638032Speter condition from a non-SMTP mailer. From Motonori 843738032Speter Nakamura. 843838032Speter Macro expand "C" line class definitions before scanning so that 843938032Speter "CX $Z" works. 844038032Speter Fix problem that caused error message to be sent while still 844138032Speter trying to send the original message if the connection 844238032Speter is closed during a DATA command after getting an error 844338032Speter on an RCPT command (pretty obscure). Problem reported 844438032Speter by John Myers of CMU. 844538032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 844638032Speter term bug. 844738032Speter Fix a nasty bug causing core dumps when returning the "warning: 844838032Speter cannot deliver for N hours -- will keep trying" message; 844943730Speter it only occurred if you had PostmasterCopy set and 845038032Speter only on some architectures. Although sendmail would 845138032Speter keep trying, it would send error messages on each 845238032Speter queue interval. This is an important fix. 845338032Speter Allow u and g options to take user and group names respectively. 845438032Speter Don't do a chdir into the queue directory in -bt mode to make 845538032Speter ruleset testing a bit easier. 845638032Speter Don't allow users to turn off logging (using -oL) on the command 845738032Speter line -- command line can only raise, not lower, logging 845838032Speter level. 845938032Speter Set $u to the original recipient on the SMTP transaction or on 846038032Speter the command line. This is only done if there is exactly 846138032Speter one recipient. Technically, this does not meet the 846238032Speter specs, because it does not guarantee a domain on the 846338032Speter address. 846438032Speter Fix a problem that dumped error messages on bad addresses if 846538032Speter you used the -t flag. Problem noted by Josh Smith of 846638032Speter Harvey Mudd College. 846738032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 846838032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 846938032Speter avoid the problem of people who use angle brackets in 847038032Speter their full name information. 847138032Speter Fix a null pointer dereference if you set option "l", have 847238032Speter an Errors-To: header in the message, and have Errors-To: 847338032Speter defined in the config file H lines. From J.R. Oldroyd. 847438032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 847538032Speter wrong when compiling. Suggested by Rick McCarty of TI. 847638032Speter Fix a problem that could pass negative SIZE parameter if the 847738032Speter df file got lost; this would cause servers to always 847838032Speter give a temporary failure, making the problem even worse. 847938032Speter Problem noted by Allan Johannesen of WPI. 848038032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 848138032Speter protocol timeouts (30s default). Requested by Murray 848238032Speter Kucherawy of HookUp Communication Corp. to handle bogus 848338032Speter PC TCP/IP implementations. 848438032Speter Change $w default definition to be just the first component of 848538032Speter the domain name on config level 5. The $j macro defaults 848638032Speter to the FQDN; $m remains as before. This lets well-behaved 848738032Speter config files use any of the short, long, or subdomain 848838032Speter names. 848938032Speter Add makesendmail script in src to try to automate multi-architecture 849038032Speter builds. I know, this is sub-optimal, but it is still 849138032Speter helpful. 849238032Speter Fix very obscure race condition that can cause a queue run to 849338032Speter get a queue file for an already completed job. This 849438032Speter problem has existed for years. Problem noted by the 849538032Speter long suffering Allan Johannesen of WPI. 849638032Speter Fix a problem that caused the raw sender name to be passed to 849738032Speter udbsender instead of the canonified name -- this caused 849838032Speter it to sometimes miss records that it should have found. 849938032Speter Relax check of name on HELO packet so that a program using -bs 850038032Speter that claims to be itself works properly. 850138032Speter Restore rewriting of $: part of address through 2, R, 4 in 850238032Speter buildaddr -- this requires passing a lot of flags to get 850338032Speter it right. Unlike old versions, this ONLY rewrites 850438032Speter recipient addresses, not sender addresses. 850538032Speter Fix a bug that caused core dumps in config files that cannot 850638032Speter resolve /file/name style addresses. Fix from Jonathan 850738032Speter Kamens of OpenVision Technologies. 850838032Speter Fix problem with fcntl locking that can cause error returns to 850938032Speter be lost if the lock is lost; this required fully 851038032Speter queueing everything, dropping the envelope (so errors 851138032Speter would get returned), and then re-reading the queue from 851238032Speter scratch. 851338032Speter Fix a problem that caused aliases that redefine an otherwise 851438032Speter true address to still send to the original address 851538032Speter if and only if the alias failed in certain bizarre 851638032Speter ways (e.g, if they pointed at a list:; syntax address). 851738032Speter Problem pointed out by Jonathan Kamens. 851838032Speter Remove support for frozen configuration files. They caused 851938032Speter more trouble than it was worth. 852038032Speter Fix problem that can cause error messages to get ignored when 852138032Speter using both -odb and -t flags. Problem noted by Rob 852238032Speter McNicholas at U.C. Berkeley. 852338032Speter Include all "normal" variations on hostname in $=w. For example, 852438032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 852538032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 852638032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 852738032Speter the queue. 852838032Speter Reset SmtpPhase global on initial connection creation so that 852938032Speter messages don't come out with stale information. 853038032Speter Pass an "ext" argument to lockfile so that error/log messages 853138032Speter will properly reflect the true filename being locked. 853238032Speter Put all [...] address forms into $=w -- this eliminates the need 853338032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 853438032Speter Myers of CMU. 853538032Speter Fix a bug that can cause qf files to be left around even after 853638032Speter an SMTP RSET command. Problem and fix from Michael 853738032Speter Corrigan. 853843730Speter Don't send a PostmasterCopy to errors when the Precedence: is 853938032Speter negative. Error reports still go to the envelope 854038032Speter sender address. 854138032Speter Add LA_SHORT for load averages. 854238032Speter Lock sendmail.st file when posting statistics. 854338032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 854438032Speter set the size of the TCP send and receive buffers; if you 854538032Speter run over a slow slip line you may need to set these down 854638032Speter (although it would be better to fix the SLIP implementation 854738032Speter so that it's not necessary to recompile every program 854838032Speter that does bulk data transfer). 854938032Speter Allow null defaults on $( ... $) lookups. Problem reported by 855038032Speter Amir Plivatsky. 855138032Speter Diagnose crufty S and V config lines. This resulted from an 855238032Speter observation that some people were using the SITE macro 855338032Speter without the SITECONFIG macro first, which was causing 855438032Speter bogus config files that were not caught. 855538032Speter Fix makemap -f flag to turn off case folding (it was turning it 855638032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 855738032Speter Fix a problem that caused multiple error messages to be sent if 855838032Speter you used "sendmail -t -oem -odb", your system uses fcntl 855938032Speter locking, and one of the recipient addresses is unknown. 856038032Speter Reset uid earlier in include() so that recursive .forwards or 856138032Speter :include:s don't use the wrong uid. 856238032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 856338032Speter called, the code to recover the descriptor was broken. 856438032Speter This sometimes (only sometimes) caused problems with the 856538032Speter alias file. Fix from Motonori Nakamura. 856638032Speter Fix a problem that caused aliaswait to go into infinite recursion 856738032Speter if the @:@ metasymbol wasn't found in the alias file. 856838032Speter Improve error message on newaliases if database files cannot be 856938032Speter opened or if running with no database format defined. 857038032Speter Do a better estimation of the size of error messages when NoReturn 857138032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 857238032Speter Fix a problem causing the "c" option (don't connect to expensive 857338032Speter mailers) to be ignored in SMTP. Problem noted and the 857438032Speter solution suggested by Robert Elz of The University of 857538032Speter Melbourne. 857638032Speter Improve connection caching algorithm by passing "[host]" to 857738032Speter hostsignature, which strips the square brackets and 857838032Speter returns the real name. This allows mailertable entries 857938032Speter to match regular entries. 858038032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 858138032Speter feature, even if it doesn't work right. 858238032Speter Catch and log attempts to try the "wiz" command in server SMTP. 858338032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 858438032Speter Be more generous at assigning $z to the home directory -- do this 858538032Speter for programs that are specified through a .forward file. 858638032Speter Fix from Andrew Chang of Sun Microsystems. 858738032Speter Always save a fatal error message in preference to a non-fatal 858838032Speter error message so that the "subject" line of return 858938032Speter messages is the best possible. 859038032Speter CONFIG: reduce the number of quotes needed to quote configuration 859138032Speter parameters with commas: two quotes should work now, e.g., 859238032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 859338032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 859438032Speter connections (domain-ized UUCP). 859538032Speter CONFIG: fix bug in default maps (-o must be before database file 859664562Sgshapiro name). Pointed out by Christophe Wolfhugel. 859738032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 859838032Speter DNS. This would presumably be used in UUCP islands. 859938032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 860038032Speter CONFIG: log $u in Received: line. This is in technical violation 860138032Speter of the standards, since it doesn't guarantee a domain 860238032Speter on the address. 860338032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 860438032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 860538032Speter the "m" flag should you want it. Apparently some Solaris 2.2 860638032Speter installations can't handle multiple local recipients. 860738032Speter Problem noted by Josh Smith. 860838032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 860938032Speter CONFIG: change default version level from 4 to 5. 861038032Speter CONFIG: add FEATURE(nullclient) to create a config file that 861138032Speter forwards all mail to a hub without ever looking at the 861238032Speter addresses in any detail. 861338032Speter CONFIG: properly strip mailer: information off of relays when 861438032Speter used to change .BITNET form into %-hack form. 861538032Speter CONFIG: fix a problem that caused infinite loops if presented 861638032Speter with an address such as "!foo". 861738032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 861838032Speter the reverse "PTR" mapping is broken. There's a better 861938032Speter way to do this, but the change is fairly major and I 862038032Speter want to hold it for another release. Problem noted by 862138032Speter Bret Marquis. 862238032Speter 862364562Sgshapiro8.5/8.5 1993/07/23 862438032Speter Serious bug: if you used a command line recipient that was unknown 862538032Speter sendmail would not send a return message (it was treating 862638032Speter everything as though it had an SMTP-style client that 862738032Speter would do the return itself). Problem noted by Josh Smith. 862838032Speter Change "trymx" option in getcanonname() to ignore all MX data, 862938032Speter even during a T_ANY query. This actually didn't break 863038032Speter anything, because the only time you called getcanonname 863138032Speter with !trymx was if you already knew there were no MX 863238032Speter records, but it is somewhat cleaner. From Motonori 863338032Speter Nakamura. 863438032Speter Don't call getcanonname from getmxrr if you already know there 863538032Speter are no DNS records matching the name. 863638032Speter Fix a problem causing error messages to always include "The 863738032Speter original message was received ... from localhost". 863838032Speter The correct original host information is now included. 863938032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 864038032Speter version of "test" doesn't have the -x flag). Change it 864138032Speter to use -f instead. From John Myers. 864238032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 864338032Speter esmtp -- it should be smtp. 864438032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 864538032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 864638032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 864738032Speter this cleans up the configs somewhat. This fixes a serious 864838032Speter problem that caused route-addrs to get mistaken as relays, 864938032Speter pointed out by John Myers. WARNING: this also causes 865038032Speter the default on SMART_HOST to change from "suucp" to 865138032Speter "relay" if you have MAILER(smtp) specified. 865238032Speter 865364562Sgshapiro8.4/8.4 1993/07/22 865438032Speter Add option `w'. If you receive a message that comes to you because 865538032Speter you are the best (lowest preference) target of an MX, and 865638032Speter you haven't explicitly recognized the source MX host in 865738032Speter your .cf file, this option will cause you to try the target 865838032Speter host directly (as if there were no MX for it at all). If 865938032Speter `w' is not set, this case is a configuration error. 866038032Speter Beware: if `w' is set, senders may get bogus errors like 866138032Speter "message timed out" or "host unknown" for problems that 866238032Speter are really configuration errors. This option is 866338032Speter disrecommended, provided only for compatibility with 866438032Speter UIUC sendmail. 866538032Speter Fix a problem that caused the incoming socket to be left open 866638032Speter when sendmail forks after the DATA command. This caused 866738032Speter calling systems to wait in FIN_WAIT_2 state until the 866838032Speter entire list was processed and the child closed -- a 866938032Speter potentially prodigious amount of time. Problem noted 867038032Speter by Neil Rickert. 867138032Speter Fix problem (created in 6.64) that caused mail sent to multiple 867238032Speter addresses, one of which was a bad address, to completely 867338032Speter suppress the sending of the message. This changes 867438032Speter handling of EF_FATALERRS somewhat, and adds an 867538032Speter EF_GLOBALERRS flag. This also fixes a potential problem 867638032Speter with duplicate error messages if there is a syntax error 867738032Speter in the header of a message that isn't noticed until late 867838032Speter in processing. Original problem pointed out by Josh Smith 867938032Speter of Harvey Mudd College. This release includes quite a bit 868038032Speter of dickering with error handling (see below). 868138032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 868238032Speter will only hurt already-broken software and should help 868338032Speter humans. 868438032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 868538032Speter compiled in. It would never read the alias file. 868638032Speter Repair unbalanced `)' and `>' (the "open" versions are already 868738032Speter repaired). 868838032Speter Logging of "done" in dropenvelope() was incorrect: it would 868938032Speter log this even when the queue file still existed. Change 869038032Speter this to only log "done" (at log level 11) when the 869138032Speter queue file is actually removed. From John Myers. 869238032Speter Log "lost connection" in server SMTP at log level 20 if there 869338032Speter is no pending transaction. Some senders just close the 869438032Speter connection rather than sending QUIT. 869538032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 869638032Speter domains that do not have MX records -- this would cause 869738032Speter the subsequent host name lookup to fail. The problem 869838032Speter only occurred if you had FEATURE(nocanonify) set. 869938032Speter Problem noted by Rick McCarty of Texas Instruments. 870038032Speter Fix invocation of setvbuf when passed a -X flag -- I had 870138032Speter unwittingly used an ANSI C extension, and this caused 870238032Speter core dumps on some machines. 870338032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 870438032Speter Previously it just gave an empty send queue, which 870538032Speter then gave either "Need RCPT (recipient)" at the DATA 870638032Speter (confusing, since you had given an RCPT command which 870738032Speter returned 250) or just dropped the email, depending on 870838032Speter whether you were running VERBose mode. Now it usually 870938032Speter diagnoses this case as "aliasing/forwarding loop broken". 871038032Speter Unfortunately, it still doesn't adequately diagnose 871138032Speter some true error conditions. 871238032Speter Add internal concept of "warning messages" using 6xx codes. 871338032Speter These are not reported only to Postmaster. Unbalanced 871438032Speter parens, brackets, and quotes are printed as 653 codes. 871538032Speter They are always mapped to 5xx codes before use in SMTP. 871638032Speter Clean up error messages to tell both the actual address that 871738032Speter failed and the alias they arose from. This makes it 871838032Speter somewhat easier to diagnose problems. Difficulty noted 871938032Speter by Motonori Nakamura. 872038032Speter Fix a problem that inappropriately added a ctladdr to addresses 872138032Speter that shouldn't have had one during a queue run. This 872238032Speter caused error messages to be handled differently during 872338032Speter a queue run than a direct run. 872438032Speter Don't print the qf name and line number if you get errors during 872538032Speter the direct run of the queue from srvrsmtp -- this was 872638032Speter just extra stuff for users to crawl through. 872738032Speter Put command line flags on second line of pid file so you can 872838032Speter auto-restart the daemon with all appropriate arguments. 872938032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 873038032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 873138032Speter restart it. 873238032Speter Remove the ``setuid(getuid())'' in main -- this caused the 873338032Speter IDENT daemon to screw up. This required that I change 873438032Speter HASSETEUID to HASSETREUID and complicate the mode 873538032Speter changing somewhat because both Ultrix and SunOS seem 873638032Speter to have a bug causing seteuid() to set the saved uid 873738032Speter as well as the effective. The program test/t_setreuid.c 873838032Speter will test to see if your implementation of setreuid(2) 873938032Speter is appropriately functional. 874038032Speter The FallBackMX (option V) handling failed to properly identify 874138032Speter fallback to yourself -- most of the code was there, 874238032Speter but it wasn't being enabled. Problem noted by Murray 874338032Speter Kucherawy of the University of Waterloo. 874438032Speter Change :include: open timeout from ETIMEDOUT to an internal 874538032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 874638032Speter with CurHostName" in error messages, which can be 874738032Speter confusing. Reported by Jonathan Kamens of OpenVision 874838032Speter Technologies. 874938032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 875038032Speter process group id. The original fix was to get around 875138032Speter some problems with recalcitrant MUAs, but it breaks 875238032Speter any call from a shell that creates a process group id 875338032Speter different from the process id. I could try to fix 875438032Speter this by diddling the tty owner (using tcsetpgrp or 875538032Speter equivalent) but this is too likely to break other 875638032Speter things. 875738032Speter Portability changes: 875838032Speter Support -M as equivalent to -oM on Ultrix -- apparently 875938032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 876038032Speter instead of using standard flags. Oh joy. This 876143730Speter behavior reported by Jon Giltner of University 876238032Speter of Colorado. 876338032Speter SGI IRIX -- this includes several changes that should 876438032Speter help other strict ANSI compilers. 876538032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 876638032Speter Corporation. 876738032Speter Solaris running the Sun C compiler (which despite the 876838032Speter documentation apparently doesn't define 876938032Speter __STDC__ by default). 877038032Speter ConvexOS from Eric Schnoebelen of Convex. 877138032Speter Sony NEWS workstations and Omron LUNA workstations from 877238032Speter Motonori Nakamura. 877338032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 877438032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 877538032Speter several people have made a good argument that this 877638032Speter creates more problems than it solves (although this 877738032Speter may prove painful in the short run). 877838032Speter CONFIG: generalize all the relays to accept a "mailer:host" 877938032Speter format. 878038032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 878138032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 878238032Speter addresses are also passed through this ruleset. 878338032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 878438032Speter internet-style addresses would "fall off the end" of 878538032Speter ruleset zero and be interpreted as local -- however, 878638032Speter the angle brackets confused the recursive call. 878738032Speter These are now diagnosed as "Unrecognized host name". 878838032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 878938032Speter ifdef(`_MAILER_USENET_') instead of 879038032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 879138032Speter of SINTEF RUNIT, Oslo. 879238032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 879338032Speter early in ruleset 0; this allows .mc authors to bypass 879438032Speter things like the "short circuit" code for local addresses. 879538032Speter Prompted by a comment by Bill Wisner of The Well. 879638032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 879738032Speter esmtp) to send SMTP mail. This allows you to default 879838032Speter to esmtp but use a mailertable or other override to 879938032Speter deal with broken servers. This logic was pointed out 880038032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 880138032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 880238032Speter environments. Ugly as sin. 880338032Speter 880464562Sgshapiro8.3/8.3 1993/07/13 880538032Speter Fix setuid problems introduced in 8.2 that caused messages 880638032Speter like "Cannot create qfXXXXXX: Invalid argument" 880738032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 880838032Speter involved a new compile flag "HASSETEUID" that takes 880938032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 881038032Speter that the POSIX interface is broken enough to break 881138032Speter some systems badly. This includes some fixes for 881238032Speter HP-UX. Also fixes problems where the real uid is 881338032Speter not reset properly on startup (from Neil Rickert). 881438032Speter Fix a problem that caused timed out messages to not report the 881538032Speter addresses that timed out. Error messages are also more 881638032Speter "user friendly". 881738032Speter Drop required bandwidth on connections from 64 bytes/sec to 881838032Speter 16 bytes/sec. 881938032Speter Further Solaris portability changes -- doesn't require the BSD 882038032Speter compatibility library. This also adds a new 882138032Speter "HASGETDTABLESIZE" compile flag which can be used if 882238032Speter you want to use getdtablesize(2) instead of sysconf(2). 882338032Speter These are loosely based on changes from David Meyer at 882438032Speter University of Oregon. This now seems to work, at least 882538032Speter for quick test cases. 882638032Speter Fix a problem that can cause duplicate error messages to be 882738032Speter sent if you are in SMTP, you send to multiple addresses, 882838032Speter and at least one of those addresses is good and points 882938032Speter to an account that has a .forward file (whew!). 883038032Speter Fix a problem causing messages to be discarded if checkcompat() 883138032Speter returned EX_TEMPFAIL (because it didn't properly mark 883238032Speter the "to" address). Problem noted by John Myers. 883338032Speter Fix dfopen to return NULL if the open failed; I was depending 883438032Speter on fdopen(-1) returning NULL, which isn't the case. This 883538032Speter isn't serious, but does result in weird error diagnoses. 883638032Speter From Michael Corrigan. 883738032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 883838032Speter messages sent through UUCP-family mailers. Suggested 883938032Speter by Bill Wisner of The Well. 884038032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 884138032Speter include a "uucp-dom" mailer that uses domain-style 884238032Speter addressing. Suggested by Bill Wisner. 884338032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 884438032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 884538032Speter Christophe Wolfhugel. 884638032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 884738032Speter 884864562Sgshapiro8.2/8.2 1993/07/11 884938032Speter Don't drop out on config file parse errors in -bt mode. 885038032Speter On older configuration files, assume option "l" (use Errors-To 885138032Speter header) for back compatibility. NOTE: this DOES NOT 885238032Speter imply an endorsement of the Errors-To: header in any way. 885338032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 885438032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 885538032Speter SMTP server to give an error on this command, and 885638032Speter logging it in the transcript can be confusing. Fix 885738032Speter from Bill Wisner. 885838032Speter IRIX compatibility changes provided by Dan Rich 885938032Speter <drich@sandman.lerc.nasa.gov>. 886038032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 886138032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 886238032Speter <juo@klinzhai.rutgers.edu> 886338032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 886438032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 886538032Speter match the other flags in that file. 886638032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 886738032Speter Save h_errno in mci struct and improve error message display. 886838032Speter Changes from Eric Wassenaar. 886938032Speter Open /dev/null for the transcript if the create of the xf file 887038032Speter failed; this avoids at least one possible null pointer 887138032Speter reference in very weird cases. From Eric Wassenaar. 887238032Speter Clean up statistics gathering; it was over-reporting because of 887338032Speter forks. From Eric Wassenaar. 887438032Speter Fix problem that causes old Return-Path: line to override new 887538032Speter Return-Path: line (conf.c needs H_FORCE to avoid 887638032Speter re-using old value). From Motonori Nakamura. 887738032Speter Fix broken -m flag in K definition -- even if -m (match only) 887838032Speter was specified, it would still replace the key with the 887938032Speter value. Noted by Rick McCarty of Texas Instruments. 888038032Speter If the name server timed out over several days, no "timed out" 888138032Speter message would ever be sent back. The timeout code 888238032Speter has been moved from markfailure() to dropenvelope() 888338032Speter so that all such failures should be diagnosed. Pointed 888438032Speter out by Christophe Wolfhugel and others. 888538032Speter Relax safefile() constraints: directories in an include or 888638032Speter forward path must be readable by self if the controlling 888738032Speter user owns the entry, readable by all otherwise (e.g., 888838032Speter when reading your .forward file, you have to own and 888938032Speter have X permission in it; everyone needs X permission in 889038032Speter the root and directories leading up to your home); 889138032Speter include files must be readable by anyone, but need not 889238032Speter be owned by you. 889338032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 889438032Speter reading a .forward file; this gets around some problems 889538032Speter on NFS mounts if root permission is not exported and 889638032Speter the user's home directory isn't x'able. 889738032Speter Additional NeXT portability enhancements from Axel Zinser. 889838032Speter Additional HP-UX portability enhancements from Brian Bullen. 889938032Speter Add a timeout around SMTP message writes; this assumes you can 890038032Speter get throughput of at least 64 bytes/second. Note that 890138032Speter this does not impact the "datafinal" default, which 890238032Speter is separate; this is just intended to work around 890338032Speter network clogs that will occur before the final dot 890438032Speter is sent. From Eric Wassenaar. 890538032Speter Change map code to set the "include null" flag adaptively -- 890638032Speter it initially tries both, but if it finds anything 890738032Speter matching without a null it never tries again with a 890838032Speter null and vice versa. If -N is specified, it never 890938032Speter tries without the null and creates new maps with a 891038032Speter null byte. If -O is specified, it never tries with 891138032Speter the null (for efficiency). If -N and -O are specified, 891238032Speter you get -NO (get it?) lookup at all, so this would 891338032Speter be a bad idea. If you don't specify either -N or -O, 891438032Speter it adapts. 891538032Speter Fix recognition of "same from address" so that MH submissions 891638032Speter will insert the appropriate full name information; 891738032Speter this used to work and got broken somewhere along the 891838032Speter way. 891938032Speter Some changes to eliminate some unnecessary SYSERRs in the 892038032Speter log. For example, if you lost a connection, don't 892138032Speter bother reporting that fact on the connection you lost. 892238032Speter Add some "extended debugging" flags to try to track down 892338032Speter why we get occasional problems with file descriptor 892438032Speter one being closed when execing a mailer; it seems to 892538032Speter only happen when there has been another error in the 892638032Speter same transaction. This requires XDEBUG, defined 892738032Speter by default in conf.h. 892838032Speter Add "-X filename" command line flag, which logs both sides of 892938032Speter all SMTP transactions. This is intended ONLY for 893038032Speter debugging bad implementations of other mailers; start 893138032Speter it up, send a message from a mailer that is failing, 893238032Speter and then kill it off and examine the indicated log. 893338032Speter This output is not intended to be particularly human 893438032Speter readable. This also adds the HASSETVBUF compile 893538032Speter flag, defaulted on if your compiler defines __STDC__. 893638032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 893738032Speter have a local net that should get direct connects, you 893838032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 893938032Speter See cf/README for an example. 894038032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 894138032Speter sites that don't use the -d flag. 894238032Speter CONFIG: hide recipient addresses as well as sender addresses 894338032Speter behind $M if FEATURE(allmasquerade) is specified; this 894438032Speter has been requested by several people, but can break 894538032Speter local aliases. For example, if you mail to "localalias" 894638032Speter this will be rewritten as "localalias@masqueradehost"; 894738032Speter although initial delivery will work, replies will be 894838032Speter broken. Use it sparingly. 894938032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 895038032Speter to qualified domains in headers. I believe this is 895138032Speter largely equivalent to the IDA feature of the same name. 895238032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 895338032Speter to override the "system name" as your UUCP name -- 895438032Speter in particular, to use domain-ized UUCP names. From 895538032Speter Bill Wisner of The Well. 895638032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 895738032Speter first. This is currently unused in the config files, 895838032Speter but could be used in a mailertable entry. 895938032Speter 896064562Sgshapiro8.1C/8.1B 1993/06/27 896138032Speter Serious security bug fix: it was possible to read any file on 896238032Speter the system, regardless of ownership and permissions. 896338032Speter If a subroutine returns a fully qualified address, return it 896438032Speter immediately instead of feeding it back into rewriting. 896538032Speter This fixes a problem with mailertable lookups. 896638032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 896738032Speter 896864562Sgshapiro8.1B/8.1A 1993/06/12 896938032Speter Serious bug fix: pattern matching backup algorithm stepped by 897038032Speter two tokens in classes instead of one.
