138032Speter SENDMAIL RELEASE NOTES 2168515Sgshapiro $Id: RELEASE_NOTES,v 8.1888 2007/04/03 23:28:40 ca Exp $ 338032Speter 438032Speter 538032SpeterThis listing shows the version of the sendmail binary, the version 638032Speterof the sendmail configuration files, the date of release, and a 738032Spetersummary of the changes in that release. 838032Speter 9168515Sgshapiro8.14.1/8.14.1 2007/04/03 10168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 11168515Sgshapiro it in its list of recipients and deliver to it if the 12168515Sgshapiro transaction is accepted. This is a regression introduced 13168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 14168515Sgshapiro found by Andy Fiddaman. 15168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 16168515Sgshapiro could not be set in 8.14.0. 17168515Sgshapiro If a server shut down the connection in response to a STARTTLS 18168515Sgshapiro command, sendmail would log a misleading error message 19168515Sgshapiro due to an internal inconsistency. Problem found by 20168515Sgshapiro Werner Wiethege. 21168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 22168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 23168515Sgshapiro Science and Mathematics. 24168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 25168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 26168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 27168515Sgshapiro m4 options for setting MaxNOOPCommands and 28168515Sgshapiro SharedMemoryKeyFile. 29168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 30168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 31168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 32168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 33168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 34168515Sgshapiro currently available macros. Problem found by Andy Fiddaman. 35168515Sgshapiro LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option 36168515Sgshapiro negotiation. Problem reported by Bryan Costales. 37168515Sgshapiro LIBMILTER: Fix several minor errors in the documentation. 38168515Sgshapiro Patches from Bryan Costales. 39168515Sgshapiro PORTABILITY FIXES: 40168515Sgshapiro AIX 5.{1,2}: libsm/util.c failed to compile due to 41168515Sgshapiro redefinition of several macros, e.g., SIG_ERR. 42168515Sgshapiro Patch from Jim Pirzyk with assistance by Bob 43168515Sgshapiro Booth, University of Illinois at Urbana-Champaign. 44168515Sgshapiro Add support for QNX.6. Patch from Sean Boudreau of QNX 45168515Sgshapiro Software Systems. 46168515Sgshapiro New Files: 47168515Sgshapiro devtools/M4/depend/QNX6.m4 48168515Sgshapiro devtools/OS/QNX.6.x 49168515Sgshapiro include/sm/os/sm_os_qnx.h 50168515Sgshapiro 51168515Sgshapiro New Files added in 8.14.0, but not shown in the release notes entry: 52168515Sgshapiro libmilter/docs/smfi_chgfrom.html 53168515Sgshapiro libmilter/docs/smfi_version.html 54168515Sgshapiro 55168515Sgshapiro8.14.0/8.14.0 2007/01/31 56168515Sgshapiro Header field values are now 8 bit clean. Notes: 57168515Sgshapiro - header field names are still restricted to 7 bit. 58168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 59168515Sgshapiro headers. 60168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 61168515Sgshapiro number of spaces after the colon would be changed to 62168515Sgshapiro exactly one space. 63168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 64168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 65168515Sgshapiro limit may be reached too early, e.g., the counter 66168515Sgshapiro may be off by a factor of 4 in case of a sequence of 67168515Sgshapiro .forward files that refer to others. Patch from 68168515Sgshapiro Motonori Nakamura of Kyoto University. 69168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 70168515Sgshapiro "sendmail -bs" can trigger an assertion because the 71168515Sgshapiro hostname of the client is undefined. It is now set 72168515Sgshapiro to "localhost" for the xxfi_connect() callback. 73168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 74168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 75168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 76168515Sgshapiro Patch from Nik Clayton. 77168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 78168515Sgshapiro permanent errors (5xy). This can be useful for testing. 79168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 80168515Sgshapiro per daemon socket: 81168515Sgshapiro DeliveryMode DeliveryMode 82168515Sgshapiro refuseLA RefuseLA 83168515Sgshapiro delayLA DelayLA 84168515Sgshapiro queueLA QueueLA 85168515Sgshapiro children MaxDaemonChildren 86168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 87168515Sgshapiro lookup key with the LDAP escaped contents of the 88168515Sgshapiro arguments specified in the map lookup. Loosely based 89168515Sgshapiro on patch from Wolfgang Hottgenroth. 90168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 91168515Sgshapiro from Nik Clayton. 92168515Sgshapiro If a client is rejected via TCP wrapper or some other check 93168515Sgshapiro performed by validate_connection() (in conf.c) then do 94168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 95168515Sgshapiro of the University of Illinois at Urbana-Champaign. 96168515Sgshapiro If a client terminates the SMTP connection during a pause 97168515Sgshapiro introduced by greet_pause, then a misleading message 98168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 99168515Sgshapiro et.al., patch from Matej Vela. 100168515Sgshapiro New command "mstat" for control socket to provide "machine 101168515Sgshapiro readable" status. 102168515Sgshapiro New named config file rule check_eom which is called at the end 103168515Sgshapiro of a message, its parameter is the size of the message. 104168515Sgshapiro If the macro {addr_type} indicates that the current address 105168515Sgshapiro is a header address it also distinguishes between 106168515Sgshapiro recipient and sender addresses (as it is done for 107168515Sgshapiro envelope addresses). 108168515Sgshapiro When a macro is set in check_relay, then its value is accessible 109168515Sgshapiro by all transactions in the same SMTP session. 110168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 111168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 112168515Sgshapiro number of "useless" commands before the SMTP server will 113168515Sgshapiro slow down responding. 114168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 115168515Sgshapiro enabled, the MTA can be asked to select a shared memory 116168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 117168515Sgshapiro a file where to store the selected key. 118168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 119168515Sgshapiro by recognizing some commands from them. If the first command 120168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 121168515Sgshapiro connection is terminated immediately. 122168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 123168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 124168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 125168515Sgshapiro New options B, z, and Z for DNS maps: 126168515Sgshapiro -B: specify a domain that is always appended to queries. 127168515Sgshapiro -z: specify the delimiter at which to cut off the result of 128168515Sgshapiro a query if it is too long. 129168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 130168515Sgshapiro to form the result of a lookup. 131168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 132168515Sgshapiro implicitly while building libsm, they must be explicitly 133168515Sgshapiro started by using "make check". 134168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 135168515Sgshapiro reported by the SATURN tool which has been developed by 136168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 137168515Sgshapiro Fix a potential race condition caused by a signal handler for 138168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 139168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 140168515Sgshapiro queue group selection. This has been disabled as it was not 141168515Sgshapiro intended. 142168515Sgshapiro New operator 'r' for the arith map to return a random number. 143168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 144168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 145168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 146168515Sgshapiro which may improve the communication performance on some 147168515Sgshapiro operating systems. Patch from John Gardiner Myers of 148168515Sgshapiro Proofpoint. 149168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 150168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 151168515Sgshapiro generate an additional blank line in the output as the last 152168515Sgshapiro line. 153168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 154168515Sgshapiro the "queue control process" (QCP) works now. 155168515Sgshapiro Increase the length of an input line to 12288 to deal with 156168515Sgshapiro really long lines during SMTP AUTH negotiations. 157168515Sgshapiro Problem noted by Werner Wiethege. 158168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 159168515Sgshapiro a missing initialization call for that case). Problem 160168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 161168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 162168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 163168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 164168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 165168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 166168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 167168515Sgshapiro the MTA will not attempt to open a statistics file on 168168515Sgshapiro each delivery. 169168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 170168515Sgshapiro clients whose IP address does not have proper reverse DNS. 171168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 172168515Sgshapiro and John Beck of Sun Microsystems. 173168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 174168515Sgshapiro clients which provide a HELO/EHLO argument which is either 175168515Sgshapiro unqualified, or is one of our own names (i.e., the server 176168515Sgshapiro name instead of the client name). Contributed by Neil 177168515Sgshapiro Rickert of Northern Illinois University and John Beck of 178168515Sgshapiro Sun Microsystems. 179168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 180168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 181168515Sgshapiro Based on contribution from William Dell Wisner. 182168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 183168515Sgshapiro the maximum line length of the smtp mailers. 184168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 185168515Sgshapiro to allow entries in the access map to be of the form 186168515Sgshapiro To:user@example.com RELAY 187168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 188168515Sgshapiro macros a milter should receive at those stages in the 189168515Sgshapiro SMTP dialogue. 190168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 191168515Sgshapiro for the HELO/EHLO command. 192168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 193168515Sgshapiro messages by using those values as second argument. 194168515Sgshapiro Patches from Nelson Fung. 195168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 196168515Sgshapiro ignores everything after it unless it is in quotes or 197168515Sgshapiro preceeded by a backslash. 198168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 199168515Sgshapiro directories, then it used for "make install" to create 200168515Sgshapiro the required installation directories. 201168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 202168515Sgshapiro executables (defaults to confCC). 203168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 204168515Sgshapiro has several changes which are listed below and documented 205168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 206168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 207168515Sgshapiro changed. It now refers only to the version of libmilter, 208168515Sgshapiro not to the protocol version (which is used only internally, 209168515Sgshapiro it is not user/milter-programmer visible). Additionally, 210168515Sgshapiro a version function smfi_version() has been introduced such 211168515Sgshapiro that a milter program can check the libmilter version also 212168515Sgshapiro at runtime which is useful if a shared library is used. 213168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 214168515Sgshapiro dynamically (i.e., at runtime) determine the available 215168515Sgshapiro protocol actions and features of the MTA and also to 216168515Sgshapiro specify which of these a milter wants to use. This allows 217168515Sgshapiro for more flexibility than hardcoding these flags in the 218168515Sgshapiro xxfi_flags field of the smfiDesc structure. 219168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 220168515Sgshapiro can act on the DATA command. 221168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 222168515Sgshapiro can receive also unknown SMTP commands. 223168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 224168515Sgshapiro can be used by the xxfi_header() callback provided the 225168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 226168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 227168515Sgshapiro xxfi_body() callback to skip over further body chunks 228168515Sgshapiro and directly advance to the xxfi_eom() callback. This 229168515Sgshapiro is useful if a milter can make a decision based on the 230168515Sgshapiro body chunks it already received without reading the entire 231168515Sgshapiro rest of the body and the milter wants to invoke functions 232168515Sgshapiro that are only available from the xxfi_eom() callback. 233168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 234168515Sgshapiro new recipients including ESMTP parameters. 235168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 236168515Sgshapiro envelope sender including ESMTP parameters. 237168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 238168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 239168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 240168515Sgshapiro a RCPT has been rejected can be checked by comparing the 241168515Sgshapiro value of the macro {rcpt_mailer} with "error". 242168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 243168515Sgshapiro wants to receive from the MTA for each protocol step 244168515Sgshapiro by invoking the function smfi_setsymlist() during option 245168515Sgshapiro negotiation. 246168515Sgshapiro LIBMILTER: A milter can receive header field values with all 247168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 248168515Sgshapiro protocol action. Also, if the flag is set then the MTA 249168515Sgshapiro does not add a leading space to headers that are added, 250168515Sgshapiro inserted, or replaced. 251168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 252168515Sgshapiro callback, the SMTP server will terminate the SMTP session 253168515Sgshapiro with that error to match the behavior of all other callbacks. 254168515Sgshapiro New Files: 255168515Sgshapiro cf/feature/badmx.m4 256168515Sgshapiro cf/feature/block_bad_helo.m4 257168515Sgshapiro cf/feature/require_rdns.m4 258168515Sgshapiro devtools/M4/UNIX/check.m4 259168515Sgshapiro include/sm/misc.h 260168515Sgshapiro include/sm/sendmail.h 261168515Sgshapiro include/sm/tailq.h 262168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 263168515Sgshapiro libmilter/docs/smfi_setsymlist.html 264168515Sgshapiro libmilter/docs/xxfi_data.html 265168515Sgshapiro libmilter/docs/xxfi_negotiate.html 266168515Sgshapiro libmilter/docs/xxfi_unknown.html 267168515Sgshapiro libmilter/example.c 268168515Sgshapiro libmilter/monitor.c 269168515Sgshapiro libmilter/worker.c 270168515Sgshapiro libsm/memstat.c 271168515Sgshapiro libsm/t-memstat.c 272168515Sgshapiro libsm/t-qic.c 273168515Sgshapiro libsm/util.c 274168515Sgshapiro sendmail/daemon.h 275168515Sgshapiro sendmail/map.h 276168515Sgshapiro 277161389Sgshapiro8.13.8/8.13.8 2006/08/09 278161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 279161389Sgshapiro the server can erroneously report that there is 280161389Sgshapiro insufficient disk space. Additionally make sure that 281161389Sgshapiro an internal variable is set properly to avoid those 282161389Sgshapiro misleading errors. Based on patch from Steve Hubert 283161389Sgshapiro of University of Washington. 284161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 285161389Sgshapiro the process that forks the daemon exited, i.e., if 286161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 287161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 288161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 289161389Sgshapiro David F. Skoll. 290161389Sgshapiro Avoid a crash when finishing due to referencing a freed variable. 291161389Sgshapiro Problem reported and diagnosed by Moritz Jodeit. 292161389Sgshapiro CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4 293161389Sgshapiro range (0..255). 294161389Sgshapiro LIBMILTER: The "hostname" argument of the xxfi_connect() callback 295161389Sgshapiro previously was the equivalent of {client_ptr}. However, 296161389Sgshapiro this did not match the documentation of the function, hence 297161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 298161389Sgshapiro about these macros. 299161389Sgshapiro 300159609Sgshapiro8.13.7/8.13.7 2006/06/14 301159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 302159609Sgshapiro crash while trying to send a mail due to a stack overflow, 303159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 304159609Sgshapiro happens because the recursion of the function mime8to7() 305159609Sgshapiro was not restricted. The function is called for MIME 8 to 306159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 307159609Sgshapiro To work around this problem, recursive calls are limited to 308159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 309159609Sgshapiro limit is treated as opaque and is not checked further. 310159609Sgshapiro Problem noted by Frank Sheiness. 311159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 312159609Sgshapiro SASL mechanisms that use the security layer, e.g., 313159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 314159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 315159609Sgshapiro a df file might have been left behind in the queue. 316159609Sgshapiro This was another side effect of the changes to the I/O 317159609Sgshapiro layer made in 8.13.6. 318159609Sgshapiro Several minor problems have been fixed that were found by a 319159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 320159609Sgshapiro distribution. See http://scan.coverity.com/ 321159609Sgshapiro Note: the scan generated also a lot of "false positives", 322159609Sgshapiro e.g., "error" reports about situations that cannot happen. 323159609Sgshapiro Most of those code places are marked with lint(1) comments 324159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 325159609Sgshapiro Hence an explicit assertion has been added in some cases 326159609Sgshapiro to avoid those false positives. 327159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 328159609Sgshapiro error then in some cases shared memory segments or pid 329159609Sgshapiro files were not removed. 330159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 331159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 332159609Sgshapiro reported by Akihiro Sagawa. 333159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 334159609Sgshapiro bug work-around. Hence if sendmail is linked against 335159609Sgshapiro either of these versions and compression is available, 336159609Sgshapiro the padding bug work-around is turned off. Based on 337159609Sgshapiro patch from Victor Duchovni of Morgan Stanley. 338159609Sgshapiro CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used 339159609Sgshapiro blackholes.mail-abuse.org as default domain for lookups, 340159609Sgshapiro however, that list is no longer available. To avoid 341159609Sgshapiro further problems, no default value is available anymore, 342159609Sgshapiro but an argument must be specified. 343159609Sgshapiro Portability: 344159609Sgshapiro Fix compilation on OSF/1 for sfsasl.c.

Also fix handling of 351157001Sgshapiro a buffer in sm_syslog() which could have been used as an 352157001Sgshapiro attack vector to exploit the unsafe handling of 353157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 354157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 355157001Sgshapiro Handle theoretical integer overflows that could triggered if 356157001Sgshapiro the server accepted headers larger than the maximum 357157001Sgshapiro (signed) integer value. This is prevented in the default 358157001Sgshapiro configuration by restricting the size of a header, and on 359157001Sgshapiro most machines memory allocations would fail before reaching 360157001Sgshapiro those values. Problems found by Phil Brass of ISS. 361157001Sgshapiro If a server returns 421 for an RSET command when trying to start 362157001Sgshapiro another transaction in a session while sending mail, do 363157001Sgshapiro not trigger an internal consistency check. Problem found 364157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 365157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 366157001Sgshapiro to a STARTTLS command despite the fact that it advertised 367157001Sgshapiro STARTTLS and that the code is not valid according to RFC 368157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 369157001Sgshapiro of a protocol error (which has been changed to a 370157001Sgshapiro temporary error in 8.13.5).

Problem noted by Juergen Georgi 624132943Sgshapiro of RUS University of Stuttgart. 625132943Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 626132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 627132943Sgshapiro Add support for LDAP recursion based on types given to attribute 628132943Sgshapiro specifications in an LDAP map definition. This allows 629132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 630132943Sgshapiro URL which will in turn be queried. See the ``LDAP 631132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 632132943Sgshapiro Based on patch from Andrew Baucom. 633132943Sgshapiro Extend the default LDAP specifications for AliasFile 634132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 635132943Sgshapiro include support for LDAP recursion via new attributes. 636132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 637132943Sgshapiro of cf/README for more information. 638132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 639132943Sgshapiro LDAP API/protocol version to use. The default depends on 640132943Sgshapiro the LDAP library. 641132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 642132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 643132943Sgshapiro and -p port. This also allows for the use of LDAP over 644132943Sgshapiro SSL and connections via named sockets if your LDAP 645132943Sgshapiro library supports it. 646132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 647132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 648132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 649132943Sgshapiro during a SMTP session then terminate it just like it is 650132943Sgshapiro done for too many bad SMTP commands. 651132943Sgshapiro Basic connection rate control support has been added: the daemon 652132943Sgshapiro maintains the number of incoming connections per client 653132943Sgshapiro IP address and total in the macros {client_rate} and 654132943Sgshapiro {total_rate}, respectively. These macros can be used 655132943Sgshapiro in the cf file to impose connection rate limits. 656132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 657132943Sgshapiro determines the length of the interval for which the 658132943Sgshapiro number of connections is stored. Based on patch from 659132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 660132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 661132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 662132943Sgshapiro If enabled by the new ruleset greet_pause (see 663132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 664132943Sgshapiro amount of time before sending the initial 220 SMTP 665132943Sgshapiro greeting. If any traffic is received before then, a 554 666132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 667132943Sgshapiro during that connection. 668132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 669132943Sgshapiro server could sleep for a very long time. Fix based on 670132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 671132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 672132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 673132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 674132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 675132943Sgshapiro misinterpret it as a permanent error. 676132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 677132943Sgshapiro all milters accepted the mail. This can increase 678132943Sgshapiro performance if many mails are rejected by milters due to 679132943Sgshapiro body scans. Based on patch from David F. Skoll. 680132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 681132943Sgshapiro header, whether provided by the client or generated by 682132943Sgshapiro sendmail. 683132943Sgshapiro New macro {client_connections} which contains the number of open 684132943Sgshapiro connections in the SMTP server for the client IP address. 685132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 686132943Sgshapiro Mines de Paris. 687132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 688132943Sgshapiro to prevent confusion caused by running sendmail stop 689132943Sgshapiro scripts two or more times, where the second and subsequent 690141858Sgshapiro runs would report misleading error messages about sendmail's 691132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 692132943Sgshapiro for a discussion of the implications of this, including 693132943Sgshapiro how to correct broken scripts which may have depended on 694132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 695132943Sgshapiro Support per-daemon input filter lists which override the default 696132943Sgshapiro filter list specified in InputMailFilters. The filters 697132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 698132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 699132943Sgshapiro your configuration relies on this behavior, you have to 700132943Sgshapiro add those names to class 'w' yourself. Problem noted 701132943Sgshapiro by Sander Eerkes. 702132943Sgshapiro Support message quarantining in the mail queue. Quarantined 703132943Sgshapiro messages are not run on normal queue displays or runs 704132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 705132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 706132943Sgshapiro The -q command line option now can specify which queue to display 707132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 708132943Sgshapiro operates on lost queue items. 709132943Sgshapiro Restricted mail queue runs and displays can be done based on the 710132943Sgshapiro quarantined reason using -qQtext to run or display 711132943Sgshapiro quarantined items if the quarantine reason contains the 712132943Sgshapiro given text. Similarly, -q!Qtext will run or display 713132943Sgshapiro quarantined items which do not have the given text in the 714132943Sgshapiro quarantine reason. 715132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 716132943Sgshapiro new -Q option. See doc/op/op.me for more information. 717132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 718132943Sgshapiro quarantine reason is shown in a new line prefixed by 719132943Sgshapiro "QUARANTINE:". 720132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 721132943Sgshapiro to quarantine messages in check_* (except check_compat) and 722132943Sgshapiro header check rulesets. The $: of the mailer triplet will 723132943Sgshapiro be used for the quarantine reason. 724132943Sgshapiro Add a new quarantine count to the mailstats collected. 725132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 726132943Sgshapiro message if it is quarantined. 727132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 728132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 729132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 730132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 731132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 732132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 733132943Sgshapiro lookup for the client IP address. Note: this is the same 734132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 735132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 736132943Sgshapiro recipients received so far in a transaction. 737132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 738132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 739132943Sgshapiro noted by Kai Schlichting. 740132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 741132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 742132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 743132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 744132943Sgshapiro Wolfhugel of France Telecom Oleane. 745132943Sgshapiro Do not silently truncate long strings in address rewriting. 746132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 747132943Sgshapiro Oceana Matrix Ltd. 748132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 749132943Sgshapiro support mutual authentication. From Kenneth Murchison of 750132943Sgshapiro Oceana Matrix Ltd. 751132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 752132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 753132943Sgshapiro format just like the STARTTLS related macros to avoid 754132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 755132943Sgshapiro Masarati of SysNet s.n.c. 756132943Sgshapiro New option AuthRealm to set the authentication realm that is 757132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 758132943Sgshapiro of the University of Manitoba. 759132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 760132943Sgshapiro successful, otherwise relaying would be allowed if 761132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 762132943Sgshapiro is active. 763132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 764132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 765132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 766132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 767132943Sgshapiro DIGEST-MD5 and LOGIN. 768132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 769132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 770132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 771132943Sgshapiro overwrite each other's pid files. 772132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 773132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 774132943Sgshapiro Wolfhugel of France Telecom. 775132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 776132943Sgshapiro LogLevel 12 or higher. 777132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 778132943Sgshapiro try to use the SMTP command VERB to propagate this option 779132943Sgshapiro to the MTA which in turn will show the delivery just like 780132943Sgshapiro it was done before the default 8.12 separation of MSP and 781132943Sgshapiro MTA. Based on patch by Per Hedeland. 782132943Sgshapiro If a daemon is refusing connections for longer than the time specified 783132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 784132943Sgshapiro to high load, log this information. Patch from John Beck 785132943Sgshapiro of Sun Microsystems. 786132943Sgshapiro Remove the ability for non-trusted users to raise the value of 787132943Sgshapiro CheckpointInterval on the command line. 788132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 789132943Sgshapiro subset of the functionality of the 's' flag. 790132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 791132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 792132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 793132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 794132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 795132943Sgshapiro causing subsequent messages to be sent instead of being 796132943Sgshapiro discarded. This also caused milter callbacks to be called 797132943Sgshapiro out of order after the SMTP session was reset. 798132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 799132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 800132943Sgshapiro further information. 801132943Sgshapiro New command line option -D logfile to send debug output to 802132943Sgshapiro the indicated log file instead of stdout. 803132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 804132943Sgshapiro queue return and warning times for delivery status 805132943Sgshapiro notifications. 806132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 807132943Sgshapiro at all. 808132943Sgshapiro Several more return values for ruleset srv_features have been added 809132943Sgshapiro to enable/disable certain features in the server per 810132943Sgshapiro connection. See doc/op/op.me for details. 811132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 812132943Sgshapiro for DaemonPortOptions. 813132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 814132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 815132943Sgshapiro of Northern Illinois University. 816132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 817132943Sgshapiro be tried as a last resort after all other fallbacks. This 818132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 819132943Sgshapiro view of inside the company, but an incomplete view of 820132943Sgshapiro outside). From John Beck of Sun Microsystems. 821132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 822132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 823132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 824132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 825132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 826132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 827132943Sgshapiro of the University of Illinois at Urbana-Champaign. 828132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 829132943Sgshapiro applications for use in the xxfi_eom() callback. 830132943Sgshapiro New macro {time} which contains the output of the time(3) function, 831132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 832132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 833132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 834132943Sgshapiro terminate the SMTP session with a 421 error message. 835132943Sgshapiro Get rid of dead code that tried to access the environment variable 836132943Sgshapiro HOSTALIASES. 837132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 838132943Sgshapiro compile with -DUSE_TTYPATH=1. 839132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 840132943Sgshapiro the header value passed in without balancing quotes, 841132943Sgshapiro parentheses, and angle brackets. Based on patch from 842132943Sgshapiro Oleg Bulyzhin. 843132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 844132943Sgshapiro angle brackets when reading in rulesets. This allows 845132943Sgshapiro rules to be written for header checks to catch strings 846132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 847132943Sgshapiro Based on patch from Oleg Bulyzhin. 848132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 849132943Sgshapiro some temporary errors like ECONNABORTED. 850132943Sgshapiro Added list of CA certificates that are used by members of the 851132943Sgshapiro sendmail consortium, see CACerts. 852132943Sgshapiro Portability: 853132943Sgshapiro Two new compile options have been added: 854132943Sgshapiro HASCLOSEFROM System has closefrom(3). 855132943Sgshapiro HASFDWALK System has fdwalk(3). 856132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 857132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 858132943Sgshapiro change to using fcntl() locking until they can fix 859132943Sgshapiro it. Be sure to update other sendmail related 860132943Sgshapiro programs to match locking techniques. 861132943Sgshapiro New compile time option NEEDINTERRNO which should be set 862132943Sgshapiro if <errno.h> does not declare errno itself. 863132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 864132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 865132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 866132943Sgshapiro Center for Scientific Computing. 867132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther). 868132943Sgshapiro Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther). 869132943Sgshapiro Remove path from compiler definition for Interix because 870132943Sgshapiro Interix 3.0 and 3.5 put gcc in different locations. 871132943Sgshapiro Also use <sys/mkdev.h> to get the correct 872132943Sgshapiro major()/minor() definitions. Based on feedback 873132943Sgshapiro from Mark Funkenhauser. 874132943Sgshapiro CONFIG: Add support for LDAP recursion to the default LDAP searches 875132943Sgshapiro for maps via new attributes. See the ``USING LDAP FOR 876132943Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README and 877132943Sgshapiro cf/sendmail.schema for more information. 878132943Sgshapiro CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER 879132943Sgshapiro is of the form "user:group" when used for submit.mc. 880132943Sgshapiro Problem noted by Carsten P. Gehrke, patch from Neil Rickert 881132943Sgshapiro of Northern Illinois University. 882132943Sgshapiro CONFIG: Add a new access DB value of QUARANTINE:reason which 883132943Sgshapiro instructs the check_* (except check_compat) to quarantine 884132943Sgshapiro the message using the given reason. 885132943Sgshapiro CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl) 886132943Sgshapiro instead of "host" to avoid problem with looking up other 887132943Sgshapiro DNS records than just A. 888132943Sgshapiro CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the 889132943Sgshapiro length of the interval for which the number of incoming 890132943Sgshapiro connections is maintained. 891132943Sgshapiro CONFIG: New FEATURE(`ratecontrol') to set the limits for connection 892132943Sgshapiro rate control for individual hosts or nets. 893132943Sgshapiro CONFIG: New FEATURE(`conncontrol') to set the limits for the 894132943Sgshapiro number of open SMTP connections for individual hosts or nets. 895132943Sgshapiro CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP 896132943Sgshapiro slamming protection described above. The feature can 897132943Sgshapiro take an argument specifying the milliseconds to wait and/or 898132943Sgshapiro use the access database to look the pause time based on 899132943Sgshapiro client hostname, domain, IP address, or subnet. 900132943Sgshapiro CONFIG: New FEATURE(`use_client_ptr') to have check_relay use 901132943Sgshapiro $&{client_ptr} as its first argument. This is useful for 902132943Sgshapiro rejections based on the unverified hostname of client, 903132943Sgshapiro which turns on the same behavior as in earlier sendmail 904132943Sgshapiro versions when delay_checks was not in use.

Cannot resolve PTR 1392102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1393102528Sgshapiro modification causes a change of behavior if an IP net/address 1394102528Sgshapiro is listed in the access map with REJECT and a host/domain 1395102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1396102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1397102528Sgshapiro change was made on request of Neil Rickert of Northern 1398102528Sgshapiro Illinois University, the side effect has been found by 1399102528Sgshapiro Stefaan Van Hoornick. 1400102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1401102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1402102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1403102528Sgshapiro University. 1404102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1405102528Sgshapiro Fix from Andrzej Filip. 1406102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1407102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1408102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1409102528Sgshapiro NULL pointer.

In previous versions this could cause mail 154694334Sgshapiro not to be delivered if a queue file is repeatedly moved 154794334Sgshapiro by an external process whenever sendmail moved it back 154894334Sgshapiro into the right place. Some precautions have been taken 154994334Sgshapiro to avoid moving queue files if not really necessary. 155094334Sgshapiro sendmail may use links to refer to queue files and it 155194334Sgshapiro may store the path of data files in queue files. Hence 155294334Sgshapiro queue files should not be moved unless those internals 155394334Sgshapiro are understood and the integrity of the files is not 155494334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 155594334Sgshapiro University. 155694334Sgshapiro If an error mail is created, and the mail is split across different 155794334Sgshapiro queue directories, and SuperSafe is off, then write the mail 155894334Sgshapiro to disk before splitting it, otherwise an assertion is 155994334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 156094334Sgshapiro of INTERMETA. 156194334Sgshapiro Fix possible race condition that could cause sendmail to forget 156294334Sgshapiro running queues.

Based on 163194334Sgshapiro patch by Bryan Costales. 163294334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 163394334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 163494334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 163594334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 163694334Sgshapiro errors. By doing so, the host was marked as having a 163794334Sgshapiro temporary problem and other mail destined for that host was 163894334Sgshapiro queued for the next queue run. Problem noted by Fletcher 163994334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 164094334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 164194334Sgshapiro and Neil Rickert of Northern Illinois University. 164294334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 164394334Sgshapiro which drop the connection instead of responding to the 164494334Sgshapiro command). 164594334Sgshapiro Portability: 164694334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 164798121Sgshapiro available. 164894334Sgshapiro Define HPUX10 when building on HP-UX 10.X.

From 165694334Sgshapiro Rajesh Somasund of Hewlett-Packard. 165794334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 165894334Sgshapiro SMTP AUTH information. This feature was actually added in 165994334Sgshapiro 8.12.0 but a release note was not included. 166094334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 166194334Sgshapiro parameter is set and the LDAP lookup returns a temporary 166294334Sgshapiro error. 166394334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 166494334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 166594334Sgshapiro Krzysztof Oledzki. 166694334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 166794334Sgshapiro initialization as aliases are not needed for the MSP. 166894334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 166994334Sgshapiro is in use. Patch from Andrzej Filip. 167094334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 167194334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 167294334Sgshapiro This will only have an effect if a parameter is specified, 167394334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 167494334Sgshapiro it is embedded in square brackets. Problem noted by 167594334Sgshapiro Theo Van Dinter of Collective Technologies. 167694334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 167794334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 167894334Sgshapiro to allow for the proper time zone on systems where the 167994334Sgshapiro default results in misleading time stamps. That is, syslog 168094334Sgshapiro time stamps and Date headers on submitted mail will use the 168194334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 168294334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 168394334Sgshapiro by Neil Rickert of Northern Illinois University. 168494334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 168594334Sgshapiro binary.

You need to create a new user and 194790792Sgshapiro a new group before installing sendmail (both called smmsp by 194890792Sgshapiro default).

Suggested 196190792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 196290792Sgshapiro (IdS). 196390792Sgshapiro Fixed problem of a global variable being used for a timeout jump 196490792Sgshapiro point where the variable could become overused for more than 196590792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 196690792Sgshapiro a corrupted stack causing a core dump. The timeout is now 196790792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 196890792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 196990792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 197090792Sgshapiro checks (group ID of RunAsUser). This allows use of a 197190792Sgshapiro set-group-ID sendmail binary for initial message submission 197290792Sgshapiro and no set-user-ID root sendmail is needed. For details 197390792Sgshapiro see sendmail/SECURITY. 197490792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 197590792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 197690792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 197790792Sgshapiro with a fallback of sendmail.cf as configuration file. See 197890792Sgshapiro sendmail/SECURITY. 197990792Sgshapiro New configuration file option UseMSP to allow group writable queue 198090792Sgshapiro files if the group is the same as that of a set-group-ID 198190792Sgshapiro sendmail binary. See sendmail/SECURITY. 198290792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 198390792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 198490792Sgshapiro is sendmail.cf (to be backward compatible). This selection 198590792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 198690792Sgshapiro file: client or mta). See sendmail/SECURITY. 198790792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 198890792Sgshapiro command has been removed. 198990792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 199090792Sgshapiro at compile time or per host (ruleset). 199190792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 199290792Sgshapiro used to look up local mail recipients; the default value 199390792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 199490792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 199590792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 199690792Sgshapiro long, to accomodate envelope splitting. File systems with 199790792Sgshapiro a 14 character file name length limit are no longer 199890792Sgshapiro supported. 199990792Sgshapiro Recipient list used for delivery now gets internally ordered by 200090792Sgshapiro hostsignature (character string version of MX RR). This orders 200190792Sgshapiro recipients for the same MX RR's together meaning smaller 200290792Sgshapiro portions of the list need to be scanned (instead of the whole 200390792Sgshapiro list) each delivery() pass to determine piggybacking. The 200490792Sgshapiro significance of the change is better the larger the recipient 200590792Sgshapiro list. Hostsignature is now created during recipient list 200690792Sgshapiro creation rather than just before delivery. 200790792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 200890792Sgshapiro piggybacking (called coincidental) extended to coattail 200990792Sgshapiro piggybacking. Rather than complete MX RR matching 201090792Sgshapiro (coincidental) piggybacking is done if just the lowest value 201190792Sgshapiro preference matches (coattail). 201290792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 201390792Sgshapiro try other MX hosts if available. 201490792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 201590792Sgshapiro outgoing (client-side) SMTP Authentication. 201690792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 201790792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 201890792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 201990792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 202090792Sgshapiro A new ruleset authinfo can be used to return client side 202190792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 202290792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 202390792Sgshapiro removed in future versions. 202490792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 202590792Sgshapiro requires 334. Mercury 1.48 is a known offender. 202690792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 202790792Sgshapiro for the security layer in SMTP AUTH (SASL). See 202890792Sgshapiro doc/op/op.me for details. 202990792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 203090792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 203190792Sgshapiro signed the presented certificate, the CN and the MD5 hash 203290792Sgshapiro of the presented certificate, respectively. 203390792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 203490792Sgshapiro New ruleset srv_features to enable/disable certain features in the 203590792Sgshapiro server per connection. See doc/op/op.me for details. 203690792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 203790792Sgshapiro recipient; useful to decide whether a conection is secure 203890792Sgshapiro enough on a per recipient basis. 203990792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 204090792Sgshapiro for STARTTLS. 204190792Sgshapiro If no certificate has been requested, the macro {verify} has the 204290792Sgshapiro value "NOT". 204390792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 204490792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 204590792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 204690792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 204790792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 204890792Sgshapiro really required. This change results in a noticable 204990792Sgshapiro performance gains on most machines. Moreover, if shared 205090792Sgshapiro memory is in use, reuse the key several times. 205190792Sgshapiro Add queue groups which can be used to group queue directories with 205290792Sgshapiro the same behavior together. See doc/op/op.me for details. 205390792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 205490792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 205590792Sgshapiro are initially sorted which may result in faster envelope 205690792Sgshapiro splitting. If the mail is submitted directly from the 205790792Sgshapiro command line, then the value also limits the number of 205890792Sgshapiro processes to deliver the envelopes; if more envelopes are 205990792Sgshapiro created they are only queued up and must be taken care of 206090792Sgshapiro by a queue run. 206190792Sgshapiro The check for 'enough disk space' now pays attention to which file 206290792Sgshapiro system each queue directory resides in. 206390792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 206490792Sgshapiro New option QueueFileMode for the default permissions of queue files. 206590792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 206690792Sgshapiro group (one or more queues in a multi-queue environment 206790792Sgshapiro collected together) to process the same work list at the 206890792Sgshapiro same time. 206990792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 207090792Sgshapiro active queue runner processes. 207190792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 207290792Sgshapiro runners per queue group. 207390792Sgshapiro Queue member selection by substring pattern matching now allows 207490792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 207590792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 207690792Sgshapiro of the queue that match during processing. 207790792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 207890792Sgshapiro periodically forking a child to process the queue, a single 207990792Sgshapiro child is forked for each queue that sleeps between queue 208090792Sgshapiro runs. A SIGHUP signal can be sent to restart this 208190792Sgshapiro persistent queue runner. 208290792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 208390792Sgshapiro sendmail process which only runs the queue at an interval: 208490792Sgshapiro sendmail -q15m). 208590792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 208690792Sgshapiro Proposed by Thom O'Connor. 208790792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 208890792Sgshapiro unless the new -qf option or -v is used. 208990792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 209090792Sgshapiro several queue runners are started by hand to avoid contention. 209190792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 209290792Sgshapiro of the qf file (older entries first). 209390792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 209490792Sgshapiro a client to specify an amount of time within which an e-mail 209590792Sgshapiro should be delivered. New option DeliverByMin added to set the 209690792Sgshapiro minimum amount of time or disable the extension. 209790792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 209890792Sgshapiro not allowed unless escaped or quoted. 209990792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 210090792Sgshapiro by Leif Johansson of Stockholm University, which was based on 210190792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 210290792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 210390792Sgshapiro Technology, Stockholm, Sweden. 210490792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 210590792Sgshapiro behavior (no MX lookups), put the name in square brackets. 210690792Sgshapiro Proposed by Thom O'Connor. 210790792Sgshapiro Use shared memory to store free space of filesystems that are used 210890792Sgshapiro for queues, if shared memory is available and if a key is set 210990792Sgshapiro via SharedMemoryKey. This minimizes the number of system 211090792Sgshapiro calls to check the available space. See doc/op/op.me for 211190792Sgshapiro details. 211290792Sgshapiro If shared memory is compiled in the option -bP can be used to print 211390792Sgshapiro the number of entries in the queue(s). 211490792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 211590792Sgshapiro and the usual documentation for details. 211690792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 211790792Sgshapiro Remove '-U' (initial user submission) command line option as 211890792Sgshapiro announced in 8.10. 211990792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 212090792Sgshapiro New macro {addr_type} which contains whether the current address is 212190792Sgshapiro an envelope sender or recipient address. Suggested by 212290792Sgshapiro Neil Rickert of Northern Illinois University. 212390792Sgshapiro Two new options for host maps: -d (retransmission timeout), 212490792Sgshapiro -r (number of retries). 212590792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 212690792Sgshapiro separator such that a lookup can return both an attribute 212790792Sgshapiro and value separated by the given separator. 212890792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 212990792Sgshapiro to map class arith. 213090792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 213190792Sgshapiro (errors that occur when sending an error message) are dropped. 213290792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 213390792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 213490792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 213590792Sgshapiro requirements for files containing secret keys. This is 213690792Sgshapiro necessary for the MSP if client authentification is used. 213790792Sgshapiro Properly handle quoted filenames for class files (to allow for 213890792Sgshapiro filenames with spaces). 213990792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 214090792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 214190792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 214290792Sgshapiro {if_addr_out} address of interface of outgoing connection. 214390792Sgshapiro {if_family_out} family of interface of outgoing connection. 214490792Sgshapiro The latter two are only set if the interface does not belong 214590792Sgshapiro to the loopback net. 214690792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 214790792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 214890792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 214990792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 215090792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 215190792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 215290792Sgshapiro all connections for a single delivery attempt to succeed. 215390792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 215490792Sgshapiro a threshold number of recipients has been rejected (option 215590792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 215690792Sgshapiro Development Group. 215790792Sgshapiro New option DelayLA to delay connections if the load averages 215890792Sgshapiro exceeds the specified value. The default of 0 does not 215990792Sgshapiro change the previous behavior. A value greater than 0 216090792Sgshapiro will cause sendmail to sleep for one second on most 216190792Sgshapiro SMTP commands and before accepting connections if that 216290792Sgshapiro load average is exceeded. 216390792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 216490792Sgshapiro recipients that are sent during a connection to a mailer. 216590792Sgshapiro This also introduces a new mailer field 'r' which defines 216690792Sgshapiro the maximum number of recipients (defaults to 100). 216790792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 216890792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 216990792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 217090792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 217190792Sgshapiro instead. 217290792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 217390792Sgshapiro builtin mailer pathnames. Use TCP instead. 217490792Sgshapiro PH map code updated to use the new libphclient API instead of the 217590792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 217690792Sgshapiro University of Illinois at Urbana-Champaign. 217790792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 217890792Sgshapiro for direct (command line) submissions. 217990792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 218090792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 218190792Sgshapiro Hagino of the KAME Project. 218290792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 218390792Sgshapiro whose content is rewritten similar to Reply-To:. 218490792Sgshapiro Proposed by Andrzej Filip. 218590792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 218690792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 218790792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 218890792Sgshapiro AUTH/STARTTLS related logfile entries. 218990792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 219090792Sgshapiro before logging. 219190792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 219290792Sgshapiro (at LogLevel 9/10 or higher). 219390792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 219490792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 219590792Sgshapiro in which most commands are rejected due to check_relay or 219690792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 219790792Sgshapiro Change logging format for cloned envelopes to be similar to that for 219890792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 219990792Sgshapiro of the Universitat Regensburg. 220090792Sgshapiro Added libsm, a C library of general purpose abstractions including 220190792Sgshapiro assertions, tracing and debugging with named debug categories, 220290792Sgshapiro exception handling, malloc debugging, resource pools, 220390792Sgshapiro portability abstractions, and an extensible buffered I/O 220490792Sgshapiro package. It will at some point replace libsmutil. 220590792Sgshapiro See libsm/index.html for details. 220690792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 220790792Sgshapiro care of by fork() and exit(). 220890792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 220990792Sgshapiro more consistent portablity amongst different platforms 221090792Sgshapiro new and old (from new libsm). 221190792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 221290792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 221390792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 221490792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 221590792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 221690792Sgshapiro synchronizations calls. 221790792Sgshapiro Add per-recipient status information to mailq -v output. 221890792Sgshapiro T_ANY queries are no longer used by sendmail. 221990792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 222090792Sgshapiro too (see include/sm/cdefs.h for more info). 222190792Sgshapiro sendmail -d now has general support for named debug categories. 222290792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 222390792Sgshapiro for details. 222490792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 222590792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 222690792Sgshapiro generated by this condition were illegal (not RFC conform). 222790792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 222890792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 222990792Sgshapiro mailer and the recipient has hence been rejected during the 223090792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 223190792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 223290792Sgshapiro that do not have postmaster defined. If an email was sent 223390792Sgshapiro from an address to which a DSN cannot be returned and 223490792Sgshapiro in which at least one recipient address is non-deliverable, 223590792Sgshapiro then that email had been delivered in each queue run. 223690792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 223790792Sgshapiro degli Studi dell'Insubria. 223890792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 223990792Sgshapiro i.e., the corresponding code is always compiled in now. 224090792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 224190792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 224290792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 224390792Sgshapiro attempting to canonify a hostname, some broken nameservers 224490792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 224590792Sgshapiro lookups. If you want to excuse this behavior, use this new 224690792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 224790792Sgshapiro Mark Roth of the University of Illinois at 224890792Sgshapiro Urbana-Champaign. 224990792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 225090792Sgshapiro noted by Joy Latten of IBM. 225190792Sgshapiro ConnectionRateThrottle limits the number of connections per second 225290792Sgshapiro to each daemon individually, not the overall number of 225390792Sgshapiro connections. 225490792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 225590792Sgshapiro sendmail to use a default alias schema as outlined in the 225690792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 225790792Sgshapiro cf/README. 225890792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 225990792Sgshapiro the first character after the class name is not a '/' or a 226090792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 226190792Sgshapiro rest of the line will be parsed as a map lookup. This 226290792Sgshapiro allows classes to be filled via a map lookup. See op.me 226390792Sgshapiro for more syntax information. Specifically, this can be 226490792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 226590792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 226690792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 226790792Sgshapiro example). 226890792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 226990792Sgshapiro the default schema used in the above two items. 227090792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 227190792Sgshapiro warning if a program being run from a mailer or file class 227290792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 227390792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 227490792Sgshapiro if a program being run from a mailer or file class 227590792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 227690792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 227790792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 227890792Sgshapiro (without quotes) will disable this and return to the 227990792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 228090792Sgshapiro Suggested by Bryan Stansell of GNAC. 228190792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 228290792Sgshapiro HELO/EHLO commands. 228390792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 228490792Sgshapiro possible protocol family which may be used for outgoing 228590792Sgshapiro connections. Restrictions placed on one family only affect 228690792Sgshapiro outgoing connections on that particular family. Because of 228790792Sgshapiro this change, the ${client_flags} macro is not set until the 228890792Sgshapiro connection is established. Based on patch from Motonori 228990792Sgshapiro Nakamura of Kyoto University. 229090792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 229190792Sgshapiro when the -bv option is given by users who are neither root 229290792Sgshapiro nor the TrustedUser so users can not read private aliases, 229390792Sgshapiro forwards, or :include: files. It also will override the -v 229490792Sgshapiro (verbose) command line option. 229590792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 229690792Sgshapiro address can't be used for the outgoing connection, fall 229790792Sgshapiro back to the settings in ClientPortOptions (if set). 229890792Sgshapiro Problem noted by John Beck of Sun Microsystems. 229990792Sgshapiro New named config file rule check_data for DATA command (input: 230090792Sgshapiro number of recipients). Based on patch from Mark Roth of 230190792Sgshapiro the University of Illinois at Urbana-Champaign. 230290792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 230390792Sgshapiro can be specified using the '#' option character. For 230490792Sgshapiro example, 'ETRN #queuegroup'. 230590792Sgshapiro If an LDAP server times out or becomes unavailable, close the 230690792Sgshapiro current connection and reopen to get to one of the fallback 230790792Sgshapiro servers. Patch from Paul Hilchey of the University of 230890792Sgshapiro British Columbia. 230990792Sgshapiro Make default error number on $#error messages 550 instead of 501 231090792Sgshapiro because 501 is not allowed on all commands. 231190792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 231290792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 231390792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 231490792Sgshapiro if required. 231590792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 231690792Sgshapiro class instead. 231790792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 231890792Sgshapiro "IPv6:" tag to identify the address properly. For example, 231990792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 232090792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 232190792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 232290792Sgshapiro MTA is running. For example, during a queue run. 232390792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 232490792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 232590792Sgshapiro Nelson of IBM. 232690792Sgshapiro The maximum number of commands before the MTA slows down when too 232790792Sgshapiro many "light weight" commands have been received are now 232890792Sgshapiro configurable during compile time. The current values and 232990792Sgshapiro their defaults are: 233090792Sgshapiro MAXBADCOMMANDS 25 unknown commands 233190792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 233290792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 233390792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 233490792Sgshapiro MAXETRNCOMMANDS 8 ETRN 233590792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 233690792Sgshapiro Costales of SL3D, Inc. 233790792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 233890792Sgshapiro ${MyMacro} is defined but also that it is not empty. 233990792Sgshapiro Properly quote usernames with special characters if they are used 234090792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 234190792Sgshapiro Meteorological Institute. 234290792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 234390792Sgshapiro messages for messages for mailing list expanded addresses 234490792Sgshapiro which are not delivered on the initial attempt. 234590792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 234690792Sgshapiro the final dot has been sent to avoid affecting future 234790792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 234890792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 234990792Sgshapiro file systems that require to call fsync() for a directory 235090792Sgshapiro if the meta-data in it has been changed. This should be 235190792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 235290792Sgshapiro See sendmail/README for further information. 235390792Sgshapiro Avoid file locking deadlock when updating the statistics file if 235490792Sgshapiro sendmail is signaled to terminate. Problem noted by 235590792Sgshapiro Christophe Wolfhugel of France Telecom. 235690792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 235790792Sgshapiro envelope is initialized. Problem noted by Kari Hurtta of 235890792Sgshapiro the Finnish Meteorological Institute. 235990792Sgshapiro Properly count recipients for DeliveryMode defer and queue. Fix 236090792Sgshapiro from Peter A. Friend of EarthLink. 236190792Sgshapiro Treat invalid hesiod lookups as permanent errors instead of 236290792Sgshapiro temporary errors. Problem noted by Russell McOrmond of 236390792Sgshapiro flora.ca. 236490792Sgshapiro Portability: 236590792Sgshapiro Remove support for AIX 2, which supports only 14 character 236690792Sgshapiro filenames and is outdated anyway. Suggested by 236790792Sgshapiro Valdis Kletnieks of Virginia Tech. 236890792Sgshapiro Change several settings for Irix 6: remove confSBINDIR, 236990792Sgshapiro i.e., use default /usr/sbin, change owner/group 237090792Sgshapiro of man pages and user-executable to root/sys, set 237190792Sgshapiro optimization limit to 0 (unlimited). Based on patch 237290792Sgshapiro from Ayamura Kikuchi, M.D, and proposal from Kari 237390792Sgshapiro Hurtta of the Finnish Meteorological Institute. 237490792Sgshapiro Do not assume LDAP support is installed by default under 237590792Sgshapiro Solaris 8 and later. 237690792Sgshapiro Add support for OpenUNIX. 237790792Sgshapiro CONFIG: Increment version number of config file to 10. 237890792Sgshapiro CONFIG: Add an install target and a README file in cf/cf. 237990792Sgshapiro CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc. 238090792Sgshapiro CONFIG: Reject empty recipient addresses (in check_rcpt). 238190792Sgshapiro CONFIG: The access map uses an option of -T<TMPF> to deal with 238290792Sgshapiro temporary lookup failures. 238390792Sgshapiro CONFIG: New value for access map: SKIP, which causes the default 238490792Sgshapiro action to be taken by aborting the search for domain names 238590792Sgshapiro or IP nets. 238690792Sgshapiro CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or 238790792Sgshapiro relay address as long as the other part allows the email 238890792Sgshapiro to get through. 238990792Sgshapiro CONFIG: Entries for virtusertable can make use of a third parameter 239090792Sgshapiro "%3" which contains "+detail" of a wildcard match, i.e., an 239190792Sgshapiro entry like user+*@domain. This allows handling of details by 239290792Sgshapiro using %1%3 as the RHS. Additionally, a "+" wildcard has been 239390792Sgshapiro introduced to match only non-empty details of addresses. 239490792Sgshapiro CONFIG: Numbers for rulesets used by MAILERs have been removed 239590792Sgshapiro and hence there is no required order within the MAILER 239690792Sgshapiro section anymore except for MAILER(`uucp') which must come 239790792Sgshapiro after MAILER(`smtp') if uucp-dom and uucp-uudom are used. 239890792Sgshapiro CONFIG: Hosts listed in the generics domain class {G} 239990792Sgshapiro (GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated 240090792Sgshapiro as canonical. Suggested by Per Hedeland of Ericsson. 240190792Sgshapiro CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup 240290792Sgshapiro in the access map which returns OK or RELAY actually 240390792Sgshapiro terminates check_* ruleset checking. 240490792Sgshapiro CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset 240590792Sgshapiro tls_rcpt, see cf/README for details. 240690792Sgshapiro CONFIG: Change format of Received: header line which reveals whether 240790792Sgshapiro STARTTLS has been used to "(version=${tls_version} 240890792Sgshapiro cipher=${cipher} bits=${cipher_bits} verify=${verify})". 240990792Sgshapiro CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks') 241090792Sgshapiro options friends/haters instead of "To:" and enable 241190792Sgshapiro specification of whole domains instead of just users. 241290792Sgshapiro Notice: this change is not backward compatible. 241390792Sgshapiro Suggested by Chris Adams from HiWAAY Informations Services. 241490792Sgshapiro CONFIG: Allow for local extensions for most new rulesets, see 241590792Sgshapiro cf/README for details. 241690792Sgshapiro CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in 241790792Sgshapiro the access map.

If sendmail needs to drop 310864562Sgshapiro these privileges and the operating system doesn't set the 310964562Sgshapiro saved-uid as well, exit with an error. Problem noted by 311064562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 311164562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 311264562Sgshapiro it populates. It is possible that some broken 311364562Sgshapiro implementations of snprintf() exist that do not do this. 311464562Sgshapiro Systems in this category should compile with 311564562Sgshapiro -DSNPRINTF_IS_BROKEN=1.

Problem 311864562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 311964562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 312064562Sgshapiro Implementation influenced by the example programs of 312164562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 312264562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 312364562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 312464562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 312564562Sgshapiro cf/README and doc/op/op.*. 312664562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 312764562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 312864562Sgshapiro ${server_name}, and ${server_addr}. These are documented 312964562Sgshapiro in cf/README and doc/op/op.*. 313064562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 313164562Sgshapiro random data. 313264562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 313364562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 313464562Sgshapiro try to use STARTTLS despite the security problems. 313564562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 313664562Sgshapiro support encryption. Based on code contributed by Tim 313764562Sgshapiro Martin of CMU. 313864562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 313964562Sgshapiro strength factor. 314064562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 314164562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 314264562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 314364562Sgshapiro of CMU. 314464562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 314564562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 314664562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 314764562Sgshapiro Fix the default family selection for DaemonPortOptions. As 314864562Sgshapiro documented, unless a family is specified in a 314964562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 315064562Sgshapiro also the default if no DaemonPortOptions value is set. 315164562Sgshapiro Therefore, IPv6 users should configure additional sockets 315264562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 315364562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 315464562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 315564562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 315664562Sgshapiro the interface information for an outgoing connection. 315764562Sgshapiro Not doing so was creating a mismatch between the socket 315864562Sgshapiro family and address used in subsequent connections if the 315964562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 316064562Sgshapiro by John Beck of Sun Microsystems. 316164562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 316264562Sgshapiro family based on the IP address. ${if_family} is no longer 316364562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 316464562Sgshapiro of Sun Microsystems. 316564562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 316664562Sgshapiro macros for both the incoming interface address/family and 316764562Sgshapiro the outgoing interface address/family. In order for M=b 316864562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 316964562Sgshapiro the incoming information in the queue file for later 317064562Sgshapiro delivery attempts. 317164562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 317264562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 317364562Sgshapiro smoe.org. 317464562Sgshapiro Add more vigilance in checking for putc() errors on output streams 317564562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 317664562Sgshapiro noted by Graeme Hewson of Oracle. 317764562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 317864562Sgshapiro Problem noted by Ajay Matia. 317964562Sgshapiro Under certain circumstances, an address could be listed as deferred 318064562Sgshapiro but would be bounced back to the sender as failed to be 318164562Sgshapiro delivered when it really should have been queued.

Problem noted by Neil Rickert 318964562Sgshapiro of Northern Illinois University. 319064562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 319164562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 319264562Sgshapiro Convert the free disk space shown in a control socket status query 319364562Sgshapiro to kilobyte units. 319464562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 319564562Sgshapiro looking up the hostname, requeue the message for a later 319664562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 319764562Sgshapiro Polytechnic. 319864562Sgshapiro Under the proper circumstances, failed connections would be recorded 319964562Sgshapiro as "Bad file number" instead of "Connection failed" in the 320064562Sgshapiro queue file and persistent host status. Problem noted by 320164562Sgshapiro Graeme Hewson of Oracle. 320264562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 320364562Sgshapiro within the hoststatus directory (e.g., lost+found). 320464562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 320564562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 320664562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 320764562Sgshapiro If a message data file can't be opened at delivery time, panic and 320864562Sgshapiro abort the attempt instead of delivering a message that 320964562Sgshapiro states "<<< No Message Collected >>>". 321064562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 321164562Sgshapiro restrictive.

Problem noted 321964562Sgshapiro by Valdis Kletnieks of Virginia Tech. 322064562Sgshapiro If a cached LDAP connection is used for multiple maps, make sure 322164562Sgshapiro only the first to open the connection is allowed to close 322264562Sgshapiro it so a later map close doesn't break the connection for 322364562Sgshapiro other maps. Problem noted by Wolfgang Hottgenroth of UUNET. 322464562Sgshapiro Netscape's LDAP libraries do not support Kerberos V4 322564562Sgshapiro authentication.

Problem noted by Michal Zalewski of the 347964562Sgshapiro "Internet for Schools" project (IdS). 348064562Sgshapiro SECURITY: There is a potential for a denial of service attack if 348164562Sgshapiro the AutoRebuildAliases option is set as a user can kill the 348264562Sgshapiro sendmail process while it is rebuilding the aliases file 348364562Sgshapiro (leaving it in an inconsistent state). This option and 348464562Sgshapiro its use is deprecated and will be removed from a future 348564562Sgshapiro version of sendmail. 348664562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 348764562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 348864562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 348964562Sgshapiro (IdS). 349064562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 349164562Sgshapiro a large number of files. See cf/README for more details. 349264562Sgshapiro The directory structure of the distribution has changed slightly 349364562Sgshapiro for easier code sharing among the programs. 349464562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 349564562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 349664562Sgshapiro which hold the client's authentication credentials, 349764562Sgshapiro the mechanism used for authentication, and the 349864562Sgshapiro authorization identity (i.e., the AUTH= parameter if 349964562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 350064562Sgshapiro On systems which use the Torek stdio library (all of the BSD 350164562Sgshapiro distributions), use memory-buffered files to reduce 350264562Sgshapiro file system overhead by not creating temporary files on 350364562Sgshapiro disk. Contributed by Exactis.com, Inc. 350464562Sgshapiro New option DataFileBufferSize to control the maximum size of a 350564562Sgshapiro memory-buffered data (df) file before a disk-based file is 350664562Sgshapiro used. Contributed by Exactis.com, Inc. 350764562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 350864562Sgshapiro memory-buffered transcript (xf) file before a disk-based 350964562Sgshapiro file is used. Contributed by Exactis.com, Inc. 351064562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 351164562Sgshapiro now listen on several different ports. Use: 351264562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 351364562Sgshapiro to run a Message Submission Agent (MSA); this is turned 351464562Sgshapiro on by default in m4-generated .cf files; it can be turned 351564562Sgshapiro off with FEATURE(`no_default_msa'). 351664562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 351764562Sgshapiro begin using RFC 2476 Message Submission for initial user 351864562Sgshapiro message submission. XUSR may disappear from a future release. 351964562Sgshapiro The new '-G' (relay (gateway) submission) command line option 352064562Sgshapiro indicates that the message being submitted from the command 352164562Sgshapiro line is for relaying, not initial submission. This means 352264562Sgshapiro the message will be rejected if the addresses are not fully 352364562Sgshapiro qualified and no canonicalization will be done. Future 352464562Sgshapiro releases may even reject improperly formed messages. 352564562Sgshapiro The '-U' (initial user submission) command line option is 352664562Sgshapiro deprecated and may be removed from a future release. 352764562Sgshapiro Mail user agents should begin using '-G' to indicate that 352864562Sgshapiro this is a relay submission (the inverse of -U). 352964562Sgshapiro The next release of sendmail will assume that any message submitted 353064562Sgshapiro from the command line is an initial user submission and act 353164562Sgshapiro accordingly. 353264562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 353364562Sgshapiro program or deliver to file as the owner of that file, the 353464562Sgshapiro address is marked as unsafe. This means if RunAsUser is 353564562Sgshapiro set, users won't be able to use programs or delivery to 353664562Sgshapiro files in their .forward files. Administrators can override 353764562Sgshapiro this by setting the DontBlameSendmail option to the new 353864562Sgshapiro setting NonRootSafeAddr. 353964562Sgshapiro Allow group or world writable directories if the sticky bit is set 354064562Sgshapiro on the directory and DontBlameSendmail is set to 354164562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 354264562Sgshapiro InCert Software. 354364562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 354464562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 354564562Sgshapiro set in the DontBlameSendmail option. Requested by many. 354664562Sgshapiro New Timeout.control option to limit the total time spent satisfying 354764562Sgshapiro a control socket request. 354864562Sgshapiro New Timeout.resolver options for controlling BIND resolver 354964562Sgshapiro settings: 355064562Sgshapiro Timeout.resolver.retrans 355164562Sgshapiro Sets the resolver's retransmission time interval (in 355264562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 355364562Sgshapiro and Timeout.resolver.retrans.normal. 355464562Sgshapiro Timeout.resolver.retrans.first 355564562Sgshapiro Sets the resolver's retransmission time interval (in 355664562Sgshapiro seconds) for the first attempt to deliver a message. 355764562Sgshapiro Timeout.resolver.retrans.normal 355864562Sgshapiro Sets the resolver's retransmission time interval (in 355964562Sgshapiro seconds) for all resolver lookups except the first 356064562Sgshapiro delivery attempt. 356164562Sgshapiro Timeout.resolver.retry 356264562Sgshapiro Sets the number of times to retransmit a resolver 356364562Sgshapiro query. Sets both Timeout.resolver.retry.first 356464562Sgshapiro and Timeout.resolver.retry.normal. 356564562Sgshapiro Timeout.resolver.retry.first 356664562Sgshapiro Sets the number of times to retransmit a resolver 356764562Sgshapiro query for the first attempt to deliver a message. 356864562Sgshapiro Timeout.resolver.retry.normal 356964562Sgshapiro Sets the number of times to retransmit a resolver 357064562Sgshapiro query for all resolver lookups except the first 357164562Sgshapiro delivery attempt. 357264562Sgshapiro Contributed by Exactis.com, Inc. 357364562Sgshapiro Support multiple queue directories. To use multiple queues, supply 357464562Sgshapiro a QueueDirectory option value ending with an asterisk. For 357564562Sgshapiro example, /var/spool/mqueue/q* will use all of the 357664562Sgshapiro directories or symbolic links to directories beginning with 357764562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 357864562Sgshapiro mind, the queue directory structure should not be changed 357964562Sgshapiro while sendmail is running. Queue runs create a separate 358064562Sgshapiro process for running each queue unless the verbose flag is 358164562Sgshapiro given on a non-daemon queue run. New items are randomly 358264562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 358364562Sgshapiro Support different directories for qf, df, and xf queue files; if 358464562Sgshapiro subdirectories or symbolic links to directories of those names 358564562Sgshapiro exist in the queue directories, they are used for the 358664562Sgshapiro corresponding queue files. Keep in mind, the queue 358764562Sgshapiro directory structure should not be changed while sendmail is 358864562Sgshapiro running. Proposed by Mathias Koerber of Singapore 358964562Sgshapiro Telecommunications Ltd. 359064562Sgshapiro New queue file naming system which uses a filename guaranteed to be 359164562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 359264562Sgshapiro without fancy file system locking. Queued items can be 359364562Sgshapiro moved between queues easily. Contributed by Exactis.com, 359464562Sgshapiro Inc. 359564562Sgshapiro Messages which are undeliverable due to temporary address failures 359664562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 359764562Sgshapiro set. Contributed by Exactis.com, Inc. 359864562Sgshapiro New command line option '-L tag' which sets the identifier used for 359964562Sgshapiro syslog. Contributed by Exactis.com, Inc. 360064562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 360164562Sgshapiro avoids opening and reading each queue file when preparing 360264562Sgshapiro to run the queue.

Use [IPC] 362564562Sgshapiro instead. 362664562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 362764562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 362864562Sgshapiro connections), IPC (which will be deprecated in a future 362964562Sgshapiro version), and FILE (for UNIX domain socket delivery). 363064562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 363164562Sgshapiro flags. 363264562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 363364562Sgshapiro body of the original message on delivery status 363464562Sgshapiro notifications. 363564562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 363664562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 363764562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 363864562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 363964562Sgshapiro Steve Schweinhart of America Online. 364064562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 364164562Sgshapiro not be set after rulesets are defined. Suggested by 364264562Sgshapiro Mitchell Blank Jr of Exec-PC. 364364562Sgshapiro Do not report temporary failure on delivery to files. In 364464562Sgshapiro interactive delivery mode, this would result in two SMTP 364564562Sgshapiro responses after the DATA command. Problem noted by 364664562Sgshapiro Nik Conwell of Boston University. 364764562Sgshapiro Check file close when mailing to files. Problem noted by Nik 364864562Sgshapiro Conwell of Boston University. 364964562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 365064562Sgshapiro Curtis W. Hillegas of Princeton University. 365164562Sgshapiro Always bind to the LDAP server regardless of whether you are using 365264562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 365364562Sgshapiro @Home Network. 365464562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 365564562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 365664562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 365764562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 365864562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 365964562Sgshapiro similar to check_rcpt etc. 366064562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 366164562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 366264562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 366364562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 366464562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 366564562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 366664562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 366764562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 366864562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 366964562Sgshapiro the corresponding DSN parameter values. Proposed by 367064562Sgshapiro Mathias Herberts. 367164562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 367264562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 367364562Sgshapiro before the message has been collected, thereafter it holds 367464562Sgshapiro the message size as computed by sendmail (and can be used 367564562Sgshapiro in check_compat). 367664562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 367764562Sgshapiro sendmail is using instead of the value of the DeliveryMode 367864562Sgshapiro option. 367964562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 368064562Sgshapiro Drop explicit From: if same as what would be generated only if it is 368164562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 368264562Sgshapiro Write pid to file also if sendmail only processes the queue. 368364562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 368464562Sgshapiro Log "low on disk space" only when necessary. 368564562Sgshapiro New macro ${load_avg} can be used to check the current load average. 368664562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 368764562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 368864562Sgshapiro is set. 368964562Sgshapiro Flag -S for maps to specify the character which is substituted 369064562Sgshapiro for spaces (instead of the default given by O BlankSub). 369164562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 369264562Sgshapiro This flag is set by default for the host map. Based on a 369364562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 369464562Sgshapiro Open maps only on demand, not at startup. 369564562Sgshapiro Log warning about unsupported IP address families. 369664562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 369764562Sgshapiro of the sum of all headers. This can be used to prevent 369864562Sgshapiro a denial-of-service attack. 369964562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 370064562Sgshapiro headers and parameters within those headers. This option 370164562Sgshapiro is intended to protect mail user agents from buffer 370264562Sgshapiro overflow attacks. 370364562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 370464562Sgshapiro alias recursion. 370564562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 370664562Sgshapiro Map type syslog to log the key via syslogd. 370764562Sgshapiro Entries in the alias file can be continued by putting a backslash 370864562Sgshapiro directly before the newline. 370964562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 371064562Sgshapiro dead.letter file, formerly hardcoded to 371164562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 371264562Sgshapiro default), sendmail will not attempt to save to a 371364562Sgshapiro system-wide dead.letter file if it can not bounce the mail 371464562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 371564562Sgshapiro file as it has in the past when the dead.letter file 371664562Sgshapiro could not be opened. 371764562Sgshapiro New option PidFile to define the location of the pid file. The 371864562Sgshapiro value of this option is macro expanded. 371964562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 372064562Sgshapiro process title shown in 'ps' listings. 372164562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 372264562Sgshapiro (along with the already existing macros): 372364562Sgshapiro ${daemon_info} Daemon information, e.g. 372464562Sgshapiro SMTP+queueing@00:30:00 372564562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 372664562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 372764562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 372864562Sgshapiro ${daemon_port} Daemon port, e.g., 25 372964562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 373064562Sgshapiro New macros especially for virtual hosting: 373164562Sgshapiro ${if_name} hostname of interface of incoming connection. 373264562Sgshapiro ${if_addr} address of interface of incoming connection. 373364562Sgshapiro The latter is only set if the interface does not belong to the 373464562Sgshapiro loopback net. 373564562Sgshapiro If a message being accepted via a method other than SMTP and 373664562Sgshapiro would be rejected by a header check, do not send the message. 373764562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 373864562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 373964562Sgshapiro Provide header value as quoted string in the macro 374064562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 374164562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 374264562Sgshapiro The length of the header value is stored in ${hdrlen}. 374364562Sgshapiro H*: allows to specify a default ruleset for header checks. This 374464562Sgshapiro ruleset will only be called if the individual header does 374564562Sgshapiro not have its own ruleset assigned. Suggested by Jan 374664562Sgshapiro Krueger of Unix-AG of University of Hannover. 374764562Sgshapiro The name of the header field stored in ${hdr_name}. 374864562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 374964562Sgshapiro removed if the config file version is greater than or equal 375064562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 375164562Sgshapiro input "token (1)" but does not match "token". 375264562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 375364562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 375464562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 375564562Sgshapiro Ericsson. 375664562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 375764562Sgshapiro messages with 8-bit text in headers. Problem noted by 375864562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 375964562Sgshapiro of Ericsson. 376064562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 376164562Sgshapiro modified database map file. Problem noted by Chris Adams 376264562Sgshapiro of Renaissance Internet Services. 376364562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 376464562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 376564562Sgshapiro queue up the message instead of bouncing it. 376664562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 376764562Sgshapiro standard does not provide any indication of what to do when 376864562Sgshapiro something other than 250 is received. Based on a patch 376964562Sgshapiro from Steve Schweinhart of America Online. 377064562Sgshapiro New option TrustedUser allows to specify a user who can own 377164562Sgshapiro important files instead of root. This requires HASFCHOWN. 377264562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 377364562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 377464562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 377564562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 377664562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 377764562Sgshapiro $? tests also whether the macro is non-null. 377864562Sgshapiro Print an error message if a mailer definition contains an invalid 377964562Sgshapiro equate name. 378064562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 378164562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 378264562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 378364562Sgshapiro mailer to return after sending all data to it. 378464562Sgshapiro Only free memory from the process list when adding a new process 378564562Sgshapiro into a previously filled slot. Previously, the memory was 378664562Sgshapiro freed at removal time. Since removal can happen in a 378764562Sgshapiro signal handler, this may leave the memory map in an 378864562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 378964562Sgshapiro David Cooley of Colby College. 379064562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 379164562Sgshapiro local users in the passwd file. The UserDB code has 379264562Sgshapiro already decided the message will be passed to another host 379364562Sgshapiro for processing. Fix from Tony Landells of Burdett 379464562Sgshapiro Buckeridge Young Limited. 379564562Sgshapiro Support LDAP authorization via either a file containing the 379664562Sgshapiro password or Kerberos V4 using the new map options 379764562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 379864562Sgshapiro distinguished_name is who to login as. The method can be 379964562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 380064562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 380164562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 380264562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 380364562Sgshapiro of Stanford University. 380464562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 380564562Sgshapiro deprecated and will be removed in a future version. 380664562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 380764562Sgshapiro and the map has the column delimiter set, it turns that 380864562Sgshapiro response into a delimiter separated string. The LDAP map 380964562Sgshapiro will traverse multiple entries as well. LDAP alias maps 381064562Sgshapiro automatically set the column delimiter to the comma. 381164562Sgshapiro Based on patch from Booker Bense of Stanford University and 381264562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 381364562Sgshapiro Support return of multiple values for a single LDAP lookup. The 381464562Sgshapiro values to be returned should be in a comma separated string. 381564562Sgshapiro For example, `-v "email,emailother"'. Patch from 381664562Sgshapiro Curtis W. Hillegas of Princeton University. 381764562Sgshapiro Allow the use of LDAP for alias maps. 381864562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 381964562Sgshapiro attributes found in the match will be returned. 382064562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 382164562Sgshapiro breaking up a single entry into multiple entries. This is 382264562Sgshapiro needed for LDAP alias file specifications to allow for 382364562Sgshapiro comma separated key and value strings. 382464562Sgshapiro Keep connections to LDAP server open instead of opening and closing 382564562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 382664562Sgshapiro connections such that multiple maps which use the same 382764562Sgshapiro host, port, bind DN, and authentication will only result in 382864562Sgshapiro a single connection to that host. 382964562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 383064562Sgshapiro Be more careful about checking for errors and freeing memory on 383164562Sgshapiro LDAP lookups. 383264562Sgshapiro Use asynchronous LDAP searches to save memory and network 383364562Sgshapiro resources. 383464562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 383564562Sgshapiro Increase portability to the Netscape LDAP libraries. 383664562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 383764562Sgshapiro replaced with the literal contents of the map lookup key -- 383864562Sgshapiro note that this means a lookup can be done using the LDAP 383964562Sgshapiro special characters. The new '%0' token can be used instead 384064562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 384164562Sgshapiro For example, if the LDAP map specification contains '-k 384264562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 384364562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 384464562Sgshapiro user attribute. Instead, if the LDAP map specification 384564562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 384664562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 384764562Sgshapiro with the name "*". 384864562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 384964562Sgshapiro more than one is returned, it is equivalent to no records 385064562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 385164562Sgshapiro alias dereference option; "-Z size" limits the number of 385264562Sgshapiro matches to return. 385364562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 385464562Sgshapiro LDAP maps. The value should only contain LDAP specific 385564562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 385664562Sgshapiro settings will be used for all LDAP maps unless they are 385764562Sgshapiro specified in the individual map specification ('K' 385864562Sgshapiro command). This option should be set before any LDAP maps 385964562Sgshapiro are defined. 386064562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 386164562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 386264562Sgshapiro Tech. 386364562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 386464562Sgshapiro particular, class entries get much smaller, which can be 386564562Sgshapiro important if you have large classes. 386664562Sgshapiro On network-related temporary failures, record the hostname which 386764562Sgshapiro gave error in the queued status message. Requested by 386864562Sgshapiro Ulrich Windl of the Universitat Regensburg. 386964562Sgshapiro Add new F=% mailer flag to allow for a store and forward 387064562Sgshapiro configuration. Mailers which have this flag will not attempt 387171345Sgshapiro delivery on initial receipt of a message or on queue runs 387264562Sgshapiro unless the queued message is selected using one of the 387364562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 387464562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 387564562Sgshapiro New option ControlSocketName which, when set, creates a daemon 387664562Sgshapiro control socket. This socket allows an external program to 387764562Sgshapiro control and query status from the running sendmail daemon 387864562Sgshapiro via a named socket, similar to the ctlinnd interface to the 387964562Sgshapiro INN news server. Access to this interface is controlled by 388064562Sgshapiro the UNIX file permissions on the named socket on most UNIX 388164562Sgshapiro systems (see sendmail/README for more information). An 388264562Sgshapiro example control program is provided as contrib/smcontrol.pl. 388364562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 388464562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 388564562Sgshapiro number of processors online on the system (if that can be 388664562Sgshapiro determined). For single processor machines, this change 388764562Sgshapiro has no effect. 388864562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 388964562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 389064562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 389164562Sgshapiro Motonori Nakamura of Kyoto University. 389264562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 389364562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 389464562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 389564562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 389664562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 389764562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 389864562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 389964562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 390064562Sgshapiro connection-based denial of service attacks. 390164562Sgshapiro Log basic information about authenticated connections at LogLevel 390264562Sgshapiro 10 or higher. 390364562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 390464562Sgshapiro information (from= syslog line). 390564562Sgshapiro Log the DSN code for each recipient if one is available as a new 390664562Sgshapiro equate (dsn=). 390764562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 3908120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 3909120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 3910120256Sgshapiro of the University of Illinois at Urbana-Champaign. 391164562Sgshapiro Detect temporary lookup failures in the host map if looking up a 391264562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 391364562Sgshapiro Finnish Meteorological Institute. 391464562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 391564562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 391664562Sgshapiro When a forward file points to an alias which runs a program, run 391764562Sgshapiro the program as the default user and the default group, not 391864562Sgshapiro the forward file user. This change also assures the 391964562Sgshapiro :include: directives in aliases are also processed using 392064562Sgshapiro the default user and group. Problem noted by Sergiu 392164562Sgshapiro Popovici of DNT Romania. 392264562Sgshapiro Prevent attempts to save a dead.letter file for a user with 392364562Sgshapiro no home directory (/no/such/directory).

If some of the recipients were rejected, it is 393064562Sgshapiro helpful to know the sender of the message. 393164562Sgshapiro Check the root directory (/) when checking a path for safety. 393264562Sgshapiro Problem noted by John Beck of Sun Microsystems. 393364562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 393464562Sgshapiro interactive and delivering to an alias which resolves to 393564562Sgshapiro multiple files. 393664562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 393764562Sgshapiro greater (see below); the help function doesn't print the 393864562Sgshapiro version of sendmail any longer, instead it is placed in 393964562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 394064562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 394164562Sgshapiro skipped and a version line (#vers) is introduced. The 394264562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 394364562Sgshapiro version is found, a warning is logged. The '#vers' 394464562Sgshapiro directive should be placed at the top of the help file. 394564562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 394664562Sgshapiro disk succeeded. Suggested by Nick Christenson. 394764562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 394864562Sgshapiro length before the attempt. 394964562Sgshapiro If a forward points to a filename for delivery, change to the 395064562Sgshapiro user's uid before checking permissions on the file. This 395164562Sgshapiro allows delivery to files on NFS mounted directories where 395264562Sgshapiro root is remapped to nobody. Problem noted by Harald 395364562Sgshapiro Daeubler of Universitaet Ulm. 395464562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 395564562Sgshapiro host status files, not all files. 395664562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 395764562Sgshapiro in the queue file for the message and set when delivery 395864562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 395964562Sgshapiro Wonderworks Inc. 396064562Sgshapiro Add support for storing information between rulesets using the new 396164562Sgshapiro macro map class. This can be used to store information 396264562Sgshapiro between queue runs as well using $={persistentMacros}. 396364562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 396464562Sgshapiro of Hannover. 396564562Sgshapiro New map class arith to allow for computations in rules. The 396664562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 396764562Sgshapiro as key. The two operands are specified as arguments; the 396864562Sgshapiro lookup returns the result of the computation. For example, 396964562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 397064562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 397164562Sgshapiro Add new syntax for header declarations which decide whether to 397264562Sgshapiro include the header based on a macro rather than a mailer 397364562Sgshapiro flag: 397464562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 397564562Sgshapiro This should be used along with $={persistentMacros}. 397664562Sgshapiro It can be used for adding headers to a message based on 397764562Sgshapiro the results of check_* and header check rulesets. 397864562Sgshapiro Allow new named config file rule check_eoh which is called after 397964562Sgshapiro all of the headers have been collected. The input to the 398064562Sgshapiro ruleset the number of headers and the size of all of the 398164562Sgshapiro headers in bytes separated by $|. This ruleset along with 398264562Sgshapiro the macro storage map can be used to correlate information 398364562Sgshapiro gathered between headers and to check for missing headers. 398464562Sgshapiro See cf/README or doc/op/op.ps for an example. 398564562Sgshapiro Change the default for the MeToo option to True to correspond 398664562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 398764562Sgshapiro option is deprecated and will be removed from a future 398864562Sgshapiro version. 398964562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 399064562Sgshapiro Change the sendmail binary default for SuperSafe to True. 399164562Sgshapiro Display ruleset names in debug and address test mode output 399264562Sgshapiro if referencing a named ruleset. 399364562Sgshapiro New mailer equate m= which will limit the number of messages 399464562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 399564562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 399664562Sgshapiro using it to sort. Now all the same domains are really run 399764562Sgshapiro through the queue together. If they have the same MX host, 399864562Sgshapiro then they will have a much better opportunity to use the 399964562Sgshapiro connection cache if available. This should be a reasonable 400064562Sgshapiro performance improvement. Patch from Randall Winchester of 400164562Sgshapiro the University of Maryland. 400264562Sgshapiro If a message is rejected by a header check ruleset, log who would 400364562Sgshapiro have received the message if it had not been rejected. 400464562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 400564562Sgshapiro queue immediately. No delivery attempt is made. 400664562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 400764562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 400864562Sgshapiro COMMANDS). 400964562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 401064562Sgshapiro but for outgoing connections. 401164562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 401264562Sgshapiro error messages and logging) and Modifiers, i.e. 401364562Sgshapiro a require authentication 401464562Sgshapiro b bind to interface through which mail has 401564562Sgshapiro been received 401664562Sgshapiro c perform hostname canonification 401764562Sgshapiro f require fully qualified hostname 401864562Sgshapiro h use name of interface for outgoing HELO 401964562Sgshapiro command 402064562Sgshapiro C don't perform hostname canonification 402164562Sgshapiro E disallow ETRN (see RFC 2476) 402264562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 402364562Sgshapiro h use name of interface for HELO command 402464562Sgshapiro The version number for queue files (qf) has been incremented to 4. 402564562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 402664562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 402764562Sgshapiro Institutes of Health. 402864562Sgshapiro If a mailer dies, print the status in decimal instead of octal 402964562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 403064562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 403164562Sgshapiro Move message priority from sender to recipient logging. Suggested by 403264562Sgshapiro Ulrich Windl of the Universitat Regensburg. 403364562Sgshapiro Add support for Berkeley DB 3.X. 403464562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 403564562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 403664562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 403764562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 403864562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 403964562Sgshapiro sub-options is set on the command line. Problem noted by 404064562Sgshapiro Graeme Hewson of Oracle. 404164562Sgshapiro Randomize equal preference MX records each time delivery is 404264562Sgshapiro attempted via a new connection to a host instead of once per 404364562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 404464562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 404564562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 404664562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 404764562Sgshapiro to hosts which have dynamically assigned names. 404864562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 404964562Sgshapiro the bounce for the same reason. If the body is not 8-bit 405064562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 405164562Sgshapiro not be included in the bounce. Problem noted by Valdis 405264562Sgshapiro Kletnieks of Virginia Tech. 405364562Sgshapiro The timeout for sending a message via SMTP has been changed from 405464562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 405564562Sgshapiro simply checks for progress on sending data every 5 minutes. 405664562Sgshapiro This will detect the inability to send information quicker 405764562Sgshapiro and reduce the number of processes simply waiting to 405864562Sgshapiro timeout. 405964562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 406064562Sgshapiro interface address structure when loading the system network 406164562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 406264562Sgshapiro Nanoteq. 406364562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 406464562Sgshapiro indicates the number of interfaces to read when probing 406564562Sgshapiro for hostnames and IP addresses for class w ($=w). The 406664562Sgshapiro default value is 512. Based on idea from Reinier 406764562Sgshapiro Bezuidenhout of Nanoteq. 406864562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 406964562Sgshapiro on load average. 407064562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 407164562Sgshapiro Northern Illinois University. 407264562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 407364562Sgshapiro envelope splitting has occurred. 407464562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 407564562Sgshapiro Luke Mewburn from RMIT University. 407664562Sgshapiro Add a "/quit" command to address test mode. 407764562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 407864562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 407964562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 408064562Sgshapiro Institute. 408164562Sgshapiro The contents of a class can now be copied to another class using 408264562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 408364562Sgshapiro the items in class $={Source} into the class $={Dest}. 408464562Sgshapiro Include original envelope's error transcript in bounces created for 408564562Sgshapiro split (owner-) envelopes to see the original errors when 408664562Sgshapiro the recipients were added. Based on fix from Motonori 408764562Sgshapiro Nakamura of Kyoto University. 408864562Sgshapiro Show reason for permanent delivery errors directly after the 408964562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 409064562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 409164562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 409264562Sgshapiro If the specification for the queue run interval (-q###) has a 409364562Sgshapiro syntax error, consider the error fatal and exit. 409464562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 409564562Sgshapiro noted by Motonori Nakamura of Kyoto University. 409664562Sgshapiro On operating systems which have setlogin(2), use it to set the 409764562Sgshapiro login name to the RunAsUserName when starting as a daemon. 409864562Sgshapiro This is for delivery to programs which use getlogin(). 409964562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 410064562Sgshapiro Differentiate between "command not implemented" and "command 410164562Sgshapiro unrecognized" in the SMTP dialogue. 410264562Sgshapiro Strip returns from forward and include files.

Non-RFC822 addresses include deliveries to 412564562Sgshapiro programs, file, DECnet, etc. 412664562Sgshapiro Fix logic for determining if a local user is using -f or -bs to 412764562Sgshapiro spoof their return address. Based on idea from Neil Rickert 412864562Sgshapiro of Northern Illinois University and patch from Per Hedeland 412964562Sgshapiro of Ericsson. 413064562Sgshapiro Report the proper UID in the bounce message if an :include: file is 413164562Sgshapiro owned by a uid that doesn't map to a username and the 413264562Sgshapiro :include: file contains delivery to a file or program. 413364562Sgshapiro Problem noted by John Beck of Sun Microsystems. 413464562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 413564562Sgshapiro the remote server responds to the first QUIT with a 4xx 413664562Sgshapiro response code and drops the connection. This behavior was 413764562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 413864562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 413964562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 414064562Sgshapiro file is not present, the lookup failure would be marked as 414164562Sgshapiro a permanent failure instead of a temporary failure. Fix 414264562Sgshapiro from Russell King of the ARM Linux Project. 414364562Sgshapiro Handle aliases or forwards which deliver to programs using tabs 414464562Sgshapiro instead of spaces between arguments.

Problem noted by Per 418064562Sgshapiro Hedeland of Ericsson. 418164562Sgshapiro mailq displays unprintable characters in addresses as their octal 418264562Sgshapiro representation and a leading backslash. This avoids problems 418364562Sgshapiro with "unprintable" characters. Problem noted by Michal 418464562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 418564562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 418664562Sgshapiro one character past the limit. This would cause subsequent 418764562Sgshapiro hops to break the line again. The '!' is now placed in 418864562Sgshapiro the last column of the limit if the line needs to be broken. 418964562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 419064562Sgshapiro from Per Hedeland of Ericsson. 419164562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 419264562Sgshapiro resolver will fall back to TCP. However, some 419364562Sgshapiro misconfigured firewalls black 53/TCP so the ANY lookup 419464562Sgshapiro fails whereas an MX or A record might succeed.

Suggested by Valdis Kletnieks of Virginia Tech. 453864562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 453964562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 454064562Sgshapiro new variable which identifies the root of the source 454164562Sgshapiro directories for all of the programs in the distribution. 454264562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 454364562Sgshapiro time. They can both still be overridden by setting the m4 454464562Sgshapiro macro. 454564562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 454664562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 454764562Sgshapiro build configurations, and places objects in obj.prefix.*/. 454864562Sgshapiro Complains as 'Build -f file' does for existing object 454964562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 455064562Sgshapiro Corporation. 455164562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 455264562Sgshapiro manual pages in the directory tree specified by 455364562Sgshapiro confMANROOTMAN. 455464562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 455564562Sgshapiro preformatted pages from the distribution. The new variable 455664562Sgshapiro confCOPY specifies the copying program. 455764562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 455864562Sgshapiro question. Suggested by Terry Lambert of Whistle 455964562Sgshapiro Communications. 456064562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 456164562Sgshapiro of the installed statistics and help files, respectively. 456264562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 456364562Sgshapiro operating system identity. Problem noted by Erik 456464562Sgshapiro Wachtenheim of Dartmouth College. 456564562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 456664562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 456764562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 456864562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 456964562Sgshapiro how to strip binaries. These are used by the new 457064562Sgshapiro install-strip target. 457164562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 457264562Sgshapiro the others (if it exists). 457364562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 457464562Sgshapiro then the default ones. 457590792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 457664562Sgshapiro as local delivery agent without LMTP mode, use 457764562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 457864562Sgshapiro to set the S flag. 457964562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 458064562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 458164562Sgshapiro Northern Illinois University. 458264562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 458364562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 458464562Sgshapiro the Finnish Meteorological Institute. 458564562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 458664562Sgshapiro MAILLOCK when compiling. Also requires linking with 458764562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 458864562Sgshapiro University. 458964562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 459064562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 459164562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 459264562Sgshapiro University. 459364562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 459464562Sgshapiro structure to the beginning of the program. This ensures that 459564562Sgshapiro the getservbyname() is done before any seteuid to a possibly 459664562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 459764562Sgshapiro on a Solaris system, this avoids syslog messages such as, 459864562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 459964562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 460064562Sgshapiro University. 460164562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 460264562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 460364562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 460464562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 460564562Sgshapiro characters (in LMTP mode), mail.local split the incoming 460664562Sgshapiro line up into 2046-character output lines (excluding the 460764562Sgshapiro newline). If an input line was 2047 characters long 460864562Sgshapiro (excluding CR-LF) and the last character was a '.', 460964562Sgshapiro mail.local saw it as the end of input, transfered it to the 461064562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 461164562Sgshapiro If the message was much longer, both sendmail and 461264562Sgshapiro mail.local would deadlock waiting for each other to read 461364562Sgshapiro what they have written. Problem noted by Peter Jeremy of 461464562Sgshapiro Alcatel Australia Limited. 461564562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 461664562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 461764562Sgshapiro Neil Rickert of Northern Illinois University. 461864562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 461964562Sgshapiro timeout to avoid starvation. 462064562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 462164562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 462264562Sgshapiro Infinite Monkeys & Co. 462364562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 462464562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 462564562Sgshapiro printed in a machine readable fashion and the stats file 462664562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 462764562Sgshapiro of Maryland. 462864562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 462964562Sgshapiro generated maps to the TrustedUser as specified in the 463064562Sgshapiro sendmail configuration file. 463164562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 463264562Sgshapiro configuration file to use for finding the TrustedUser 463364562Sgshapiro option. 463464562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 463564562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 463664562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 463764562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 463864562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 463964562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 464064562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 464164562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 464264562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 464364562Sgshapiro Corporation UK. 464464562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 464564562Sgshapiro (e.g., sendmail would not drop root privileges if the 464664562Sgshapiro option was specified on the command line). Problem noted 464764562Sgshapiro by Todd C. Miller of Courtesan Consulting. 464864562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 464964562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 465064562Sgshapiro Institute for Global Communications. 465164562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 465264562Sgshapiro alias file(s) if the -f option is not used. Patch from 465364562Sgshapiro John Beck of Sun Microsystems. 465464562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 465564562Sgshapiro configuration file to use for finding alias file(s). Patch 465664562Sgshapiro from John Beck of Sun Microsystems. 465764562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 465864562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 465964562Sgshapiro of the Institute for Global Communications. 466064562Sgshapiro SMRSH: Update README for the new Build system. From Tim Pierce 466164562Sgshapiro of RootsWeb Genealogical Data Cooperative. 466264562Sgshapiro VACATION: Added vacation auto-responder to sendmail distribution. 466364562Sgshapiro LIBSMDB: Added abstracted database library. Works with Berkeley 466464562Sgshapiro DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM. 466564562Sgshapiro Changed Files: 466664562Sgshapiro The Build script in the various program subdirectories are 466764562Sgshapiro no longer symbolic links. They are now scripts 466864562Sgshapiro which execute the actual Build script in 466964562Sgshapiro devtools/bin. 467064562Sgshapiro All the manual pages are now written against -man and not 467164562Sgshapiro -mandoc as they were previously. 467264562Sgshapiro Add a simple Makefile to every directory so make instead 467364562Sgshapiro of Build will work (unless parameters are 467464562Sgshapiro required for Build). 467564562Sgshapiro New Directories: 467664562Sgshapiro devtools/M4/UNIX 467764562Sgshapiro include 467864562Sgshapiro libmilter 467964562Sgshapiro libsmdb 468064562Sgshapiro libsmutil 468164562Sgshapiro vacation 468264562Sgshapiro Renamed Directories: 468364562Sgshapiro BuildTools => devtools 468464562Sgshapiro src => sendmail 468564562Sgshapiro Deleted Files: 468664562Sgshapiro cf/m4/nullrelay.m4 468764562Sgshapiro devtools/OS/Linux.ppc 468864562Sgshapiro devtools/OS/ReliantUNIX 468964562Sgshapiro devtools/OS/SINIX 469064562Sgshapiro sendmail/ldap_map.h 469164562Sgshapiro New Files: 469264562Sgshapiro INSTALL 469364562Sgshapiro PGPKEYS 469464562Sgshapiro cf/cf/generic-linux.cf 469564562Sgshapiro cf/cf/generic-linux.mc 469664562Sgshapiro cf/feature/delay_checks.m4 469764562Sgshapiro cf/feature/dnsbl.m4 469864562Sgshapiro cf/feature/generics_entire_domain.m4 469964562Sgshapiro cf/feature/no_default_msa.m4 470064562Sgshapiro cf/feature/relay_mail_from.m4 470164562Sgshapiro cf/feature/virtuser_entire_domain.m4 470264562Sgshapiro cf/mailer/qpage.m4 470364562Sgshapiro cf/ostype/bsdi.m4 470464562Sgshapiro cf/ostype/hpux11.m4 470564562Sgshapiro cf/ostype/openbsd.m4 470664562Sgshapiro contrib/bounce-resender.pl 470764562Sgshapiro contrib/domainmap.m4 470864562Sgshapiro contrib/qtool.8 470964562Sgshapiro contrib/qtool.pl 471064562Sgshapiro devtools/M4/depend/AIX.m4 471164562Sgshapiro devtools/M4/list.m4 471264562Sgshapiro devtools/M4/string.m4 471364562Sgshapiro devtools/M4/subst_ext.m4 471464562Sgshapiro devtools/M4/switch.m4 471564562Sgshapiro devtools/OS/Darwin 471664562Sgshapiro devtools/OS/GNU 471764562Sgshapiro devtools/OS/SINIX.5.43 471864562Sgshapiro devtools/OS/SINIX.5.44 471964562Sgshapiro devtools/OS/m88k 472064562Sgshapiro devtools/bin/find_in_path.sh 472164562Sgshapiro mail.local/Makefile 472264562Sgshapiro mailstats/Makefile 472364562Sgshapiro makemap/Makefile 472464562Sgshapiro praliases/Makefile 472564562Sgshapiro rmail/Makefile 472664562Sgshapiro sendmail/Makefile 472764562Sgshapiro sendmail/bf.h 472864562Sgshapiro sendmail/bf_portable.c 472964562Sgshapiro sendmail/bf_portable.h 473064562Sgshapiro sendmail/bf_torek.c 473164562Sgshapiro sendmail/bf_torek.h 473264562Sgshapiro sendmail/shmticklib.c 473364562Sgshapiro sendmail/statusd_shm.h 473464562Sgshapiro sendmail/timers.c 473564562Sgshapiro sendmail/timers.h 473664562Sgshapiro smrsh/Makefile 473764562Sgshapiro vacation/Makefile 473864562Sgshapiro Renamed Files: 473964562Sgshapiro cf/ostype/gnuhurd.m4 => cf/ostype/gnu.m4 474064562Sgshapiro sendmail/cdefs.h => include/sendmail/cdefs.h 474164562Sgshapiro sendmail/sendmail.hf => sendmail/helpfile 474264562Sgshapiro sendmail/mailstats.h => include/sendmail/mailstats.h 474364562Sgshapiro sendmail/pathnames.h => include/sendmail/pathnames.h 474464562Sgshapiro sendmail/safefile.c => libsmutil/safefile.c 474564562Sgshapiro sendmail/snprintf.c => libsmutil/snprintf.c 474664562Sgshapiro sendmail/useful.h => include/sendmail/useful.h 474764562Sgshapiro cf/ostype/solaris2.m4 => cf/ostype/solaris2.pre5.m4 474864562Sgshapiro Copied Files: 474964562Sgshapiro cf/ostype/solaris2.ml.m4 => cf/ostype/solaris2.m4 475064562Sgshapiro 475164562Sgshapiro8.9.3/8.9.3 1999/02/04 475243730Speter SECURITY: Limit message headers to a maximum of 32K bytes (total 475343730Speter of all headers in a single message) to prevent a denial of 475443730Speter service attack.

This can be used to help prevent relaying. 519338032Speter Patch from Mitchell Blank Jr of Exec-PC. 519438032Speter Mark failures for the *file* mailer and return bounce messages to the 519538032Speter sender for those failures. 519638032Speter Prevent bogus syslog timestamps on errors in sendmail.cf by 519738032Speter preserving the TZ environment variable until TimeZoneSpec 519838032Speter has been determined. Problem noted by Ralf Hildebrandt of 519938032Speter Technical University of Braunschweig. Patch from Per Hedeland 520038032Speter of Ericsson. 520138032Speter Print test input in address test mode when input is not from the tty 520264562Sgshapiro when the -v flag is given (i.e., sendmail -bt -v) to make 520338032Speter output easier to decipher. Problem noted by Aidan Nichol 520438032Speter of Procter & Gamble. 520538032Speter The LDAP map -s flag was not properly parsed and the error message 520664562Sgshapiro given included the remainder of the arguments instead of 520738032Speter solely the argument in error. Problem noted by Aidan Nichol 520838032Speter of Procter & Gamble. 520938032Speter New DontBlameSendmail option. This option allows administrators to 521038032Speter bypass some of sendmail's file security checks at the expense 521138032Speter of system security. This should only be used if you are 521238032Speter absolutely sure you know the consequences. The available 521338032Speter DontBlameSendmail options are: 521438032Speter Safe 521538032Speter AssumeSafeChown 521638032Speter ClassFileInUnsafeDirPath 521738032Speter ErrorHeaderInUnsafeDirPath 521838032Speter GroupWritableDirPathSafe 521938032Speter GroupWritableForwardFileSafe 522038032Speter GroupWritableIncludeFileSafe 522138032Speter GroupWritableAliasFile 522238032Speter HelpFileinUnsafeDirPath 522338032Speter WorldWritableAliasFile 522438032Speter ForwardFileInGroupWritableDirPath 522538032Speter IncludeFileInGroupWritableDirPath 522638032Speter ForwardFileInUnsafeDirPath 522738032Speter IncludeFileInUnsafeDirPath 522838032Speter ForwardFileInUnsafeDirPathSafe 522938032Speter IncludeFileInUnsafeDirPathSafe 523038032Speter MapInUnsafeDirPath 523138032Speter LinkedAliasFileInWritableDir 523238032Speter LinkedClassFileInWritableDir 523338032Speter LinkedForwardFileInWritableDir 523438032Speter LinkedIncludeFileInWritableDir 523538032Speter LinkedMapInWritableDir 523638032Speter LinkedServiceSwitchFileInWritableDir 523738032Speter FileDeliveryToHardLink 523838032Speter FileDeliveryToSymLink 523938032Speter WriteMapToHardLink 524038032Speter WriteMapToSymLink 524138032Speter WriteStatsToHardLink 524238032Speter WriteStatsToSymLink 524338032Speter RunProgramInUnsafeDirPath 524438032Speter RunWritableProgram 524538032Speter New DontProbeInterfaces option to turn off the inclusion of all the 524638032Speter interface names in $=w on startup. In particular, if you 524738032Speter have lots of virtual interfaces, this option will speed up 524838032Speter startup. However, unless you make other arrangements, mail 524938032Speter sent to those addresses will be bounced. 525038032Speter Automatically create alias databases if they don't exist and 525138032Speter AutoRebuildAliases is set. 525238032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 525338032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 525438032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 525538032Speter When determining the client host name ($&{client_name} macro), do 525638032Speter a forward (A) DNS lookup on the result of the PTR lookup 525738032Speter and compare results. If they differ or if the PTR lookup 525838032Speter fails, &{client_name} will contain the IP address 525964562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 526038032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 526138032Speter (i.e, it is like -ax for the temporary failure case, in 526238032Speter contrast to the success case). 526338032Speter New syntax to do limited checking of header syntax. A config line 526438032Speter of the form: 526538032Speter HHeader: $>Ruleset 526638032Speter causes the indicated Ruleset to be invoked on the Header 526738032Speter when read. This ruleset works like the check_* rulesets -- 526838032Speter that is, it can reject mail on the basis of the contents. 526938032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 527038032Speter from hiding their connection information in Received: 527138032Speter headers. 527238032Speter When SingleThreadDelivery is active, deliveries to locked hosts 527338032Speter are skipped. This will cause the delivering process to 527438032Speter try the next MX host or queue the message if no other MX 527538032Speter hosts are available. Suggested by Alexander Litvin. 527638032Speter The [FILE] mailer type now delivers to the file specified in the 527738032Speter A= equate of the mailer definition instead of $u. It also 527838032Speter obeys all of the F= mailer flags such as the MIME 527938032Speter 7/8 bit conversion flags. This is useful for defining 528038032Speter a mailer which delivers to the same file regardless of the 528164562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 528238032Speter Do not assume the identity of a remote connection is root@localhost 528338032Speter if the remote connection closes the socket before the 528438032Speter remote identity can be queried. 528538032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 528638032Speter Some mailers, including procmail, require that the real 528738032Speter uid is left unchanged by sendmail. Problem noted by Per 528838032Speter Hedeland of Ericsson. 528938032Speter No longer is the src/obj*/Makefile selected from a large list -- it 529038032Speter is now generated using the information in BuildTools/OS/ -- 529138032Speter some of the details are determined dynamically via 529238032Speter BuildTools/bin/configure.sh. 529338032Speter The other programs in the sendmail distribution -- mail.local, 529438032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 529538032Speter the new Build method which creates an operating system 529638032Speter specific Makefile using the information in BuildTools. 529738032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 529838032Speter a failure on one message won't affect future messages to the 529938032Speter same host). This is necessary if the remote host sends 530038032Speter a 451 error if the domain of the sender does not resolve 530138032Speter as is common in anti-spam configurations. Problem noted 530238032Speter by Mitchell Blank Jr of Exec-PC. 530338032Speter New "discard" mailer for check_* rulesets and header checking 530438032Speter rulesets. If one of the above rulesets resolves to the 530538032Speter $#discard mailer, the commands will be accepted but the 530638032Speter message will be completely discarded after it is accepting. 530738032Speter This means that even if only one of the recipients 530838032Speter resolves to the $#discard mailer, none of the recipients 530938032Speter will receive the mail. Suggested by Brian Kantor. 531038032Speter All but the last cloned envelope of a split envelope were queued 531138032Speter instead of being delivered. Problem noted by John Caruso 531238032Speter of CNET: The Computer Network. 531338032Speter Fix deadlock situation in persistent host status file locking. 531438032Speter Syslog an error if a user forward file could not be read due to 531538032Speter an error. Patch from John Beck of Sun Microsystems. 531638032Speter Use the first name returned on machine lookups when canonifying a 531738032Speter hostname via NetInfo. Patch from Timm Wetzel of GWDG. 531838032Speter Clear the $&{client_addr}, $&{client_name}, and $&{client_port} 531938032Speter macros when delivering a bounce message to prevent 532038032Speter rejection by a check_compat ruleset which uses these macros. 532138032Speter Problem noted by Jens Hamisch of AgiX Internetservices GmbH. 532238032Speter If the check_relay ruleset resolves to the the error mailer, the 532338032Speter error in the $: portion of the resolved triplet is used 532438032Speter in the rejection message given to the remote machine. 532538032Speter Suggested by Scott Gifford of The Internet Ramp. 532638032Speter Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros 532738032Speter before calling the check_relay ruleset. Suggested by Scott 532838032Speter Gifford of The Internet Ramp. 532938032Speter Sendmail would get a segmentation fault if a mailer exited with an 533038032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 533138032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 533238032Speter Institute. 533338032Speter Separate snprintf/vsnprintf routines into separate file for use by 533438032Speter mail.local. 533538032Speter Allow multiple map lookups on right hand side, e.g., 533638032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 533738032Speter Christophe Wolfhugel of the Pasteur Institute. 533838032Speter Properly generate success DSN messages if requested for aliases 533938032Speter which have owner- aliases. Problem noted by Kari Hurtta 534038032Speter of the Finnish Meteorological Institute. 534138032Speter Properly display delayed-expansion macros ($&{macroname}) in 534238032Speter address test mode (-bt). Problem noted by Bryan Costales 534338032Speter of InfoBeat, Inc. 534438032Speter -qR could sometimes match names incorrectly. Problem noted by 534538032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 534638032Speter Include a magic number and version in the StatusFile for the 534738032Speter mailstats command. 534838032Speter Record the number of rejected and discarded messages in the 534938032Speter StatusFile for display by the mailstats command. Patch 535038032Speter from Randall Winchester of the University of Maryland. 535138032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 535238032Speter user portion as IDENT:username@site instead of 535338032Speter username@site to differentiate the two. Suggested by 535438032Speter Kari Hurtta of the Finnish Meteorological Institute. 535538032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 535638032Speter Ericsson. 535738032Speter Change persistent host status filename substitution so '/' is 535838032Speter replaced by ':' instead of '|' to avoid clashes. Also 535938032Speter avoid clashes with hostnames with leading dots. Fix from 536038032Speter Mitchell Blank Jr. of Exec-PC. 536138032Speter If the system lock table is full, only attempt to create a new 536238032Speter queue entry five times before giving up. Previously, it 536338032Speter was attempted indefinitely which could cause the partition 536438032Speter to run out of inodes. Problem noted by Suzie Weigand of 536538032Speter Stratus Computer, Inc. 536638032Speter In verbose mode, warn if the sendmail.cf version is less than the 536738032Speter currently supported version. 536838032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 536938032Speter from Randall S.

The default is hash. Patch from 541538032Speter Robert Harker of Harker Systems. 541638032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 541738032Speter directory for certain programs. 541838032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 541938032Speter local mail delivery. By the default, /usr/libexec/mail.local 542038032Speter is used. This is expected to be the mail.local shipped 542138032Speter with 8.9 which is LMTP capable. The path is based on the 542238032Speter new confEBINDIR m4 variable. 542338032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 542438032Speter FEATURE(smrsh). Note that this changes the default from 542538032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 542638032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 542738032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 542838032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 542938032Speter the user to setup different .forward files for 543038032Speter user+detail addressing. 543138032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 543238032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 543338032Speter DontProbeInterfaces, and DontBlameSendmail options. 543438032Speter CONFIG: by default do not allow relaying (that is, accepting mail 543538032Speter from outside your domain and sending it to another host 543638032Speter outside your domain). 543738032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 543838032Speter any site to any site. 543938032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 544038032Speter domain as defined by the 'm' class ($=m) to relay. 544138032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 544238032Speter the MX records of the host portion of an incoming recipient. 544338032Speter CONFIG: new FEATURE(access_db) which turns on the access database 544477349Sgshapiro feature. This database gives you the ability to allow 544538032Speter or refuse to accept mail from specified domains for 544638032Speter administrative reasons. By default, names that are listed 544738032Speter as "OK" in the access db are domain names, not host names. 544838032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 544938032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 545038032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 545138032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 545238032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 545338032Speter of FEATURE(access_db) and class 'R' to lookup individual 545438032Speter host names only. 545538032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 545638032Speter using % addressing is used, e.g. user%site@othersite, 545738032Speter and othersite is in class 'R', the check_rcpt ruleset 545838032Speter will strip @othersite and recheck user@site for relaying. 545938032Speter This feature changes that behavior. It should not be 546038032Speter needed for most installations. 546138032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 546238032Speter domain portion of the mail sender is a local host. This 546338032Speter should only be used if absolutely necessary as it opens 546438032Speter a window for spammers. Patch from Randall S. Winchester of 546538032Speter the University of Maryland. 546638032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 546738032Speter block incoming mail destined for certain recipient 546838032Speter usernames, hostnames, or addresses. 546938032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 547038032Speter refused if the host part of the argument to MAIL FROM: cannot 547138032Speter be located in the host name service (e.g., DNS). 547238032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 547338032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 547438032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 547538032Speter MAIL FROM: senders which do not include a domain. 547638032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 547738032Speter Realtime Blackhole List. You can specify the RBL name 547838032Speter server to contact by specifying it as an optional argument. 547938032Speter The default is rbl.maps.vix.com. For details, see 548038032Speter http://maps.vix.com/rbl/. 548138032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 548238032Speter Local_check_rcpt from check_relay, check_mail, and 548338032Speter check_rcpt. Users with local rulesets should place the 548438032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 548538032Speter returns $#OK, the message is accepted. If the ruleset 548638032Speter returns a mailer, the appropriate action is taken, else 548738032Speter the return of the ruleset is ignored. 548838032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 548938032Speter default to support file, :include:, and program deliveries. 549038032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 549138032Speter pick the proper default value.

Problem noted by Kari Hurtta of the Finnish 562538032Speter Meteorological Institute. 562638032Speter If /usr/tmp/dead.letter already existed, sendmail could not 562738032Speter add additional bounces to it. Problem noted by Thomas J. 562838032Speter Arseneault of SRI International. 562938032Speter If an SMTP mailer used a non-standard port number for the outgoing 563038032Speter connection, it would be displayed incorrectly in verbose mode. 563138032Speter Problem noted by John Kennedy of Cal State University, Chico. 563238032Speter Log the ETRN parameter specified by the client before altering them 563338032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 563438032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 563538032Speter User unknown with bogus delay= values. Change them to log 563638032Speter the same as compliant addresses. Problem noted by Kari E. 563738032Speter Hurtta of the Finnish Meteorological Institute. 563838032Speter Ignore the debug resolver option unless using sendmail debug trace 563938032Speter option for resolver. Problem noted by Greg Nichols of Wind 564038032Speter River Systems. 564138032Speter If SingleThreadDelivery was enabled and the remote server returned a 564238032Speter protocol error on the DATA command, the connection would be 564338032Speter closed but the persistent host status file would not be 564438032Speter unlocked so other sendmail processes could not deliver to 564538032Speter that host. Problem noted by Peter Wemm of DIALix. 564638032Speter If queueing up a message due to an expensive mailer, don't increment 564738032Speter the number of delivery attempts or set the last delivery 564838032Speter attempt time so the message will be delivered on the next 564938032Speter queue run regardless of MinQueueAge. Problem noted by 565038032Speter Brian J. Coan of the Institute for Global Communications. 565138032Speter Authentication warnings of "Processed from queue _directory_" and 565238032Speter "Processed by _username_ with -C _filename_" would be logged 565338032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 565438032Speter of the Finnish Meteorological Institute. 565538032Speter Use a better heuristic for detecting GDBM. 565638032Speter Log null connections on dropped connections. Problem noted by 565738032Speter Jon Lewis of Florida Digital Turnpike. 565838032Speter If class dbm maps are rebuilt, sendmail will now detect this and 565938032Speter reopen the map. Previously, they could give stale 566038032Speter results during a single message processing (but would 566138032Speter recover when the next message was received). Fix from 566238032Speter Joe Pruett of Q7 Enterprises. 566338032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 566438032Speter requests. Problem noted by Kari E. Hurtta of the 566538032Speter Finnish Meteorological Institute. 566638032Speter Do not send a bounce message back to the sender regarding bad 566738032Speter recipients if the SMTP connection is dropped before the 566838032Speter message is accepted. Problem noted by Kari E. Hurtta of the 566938032Speter Finnish Meteorological Institute. 567038032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 567138032Speter sendmail via a UNIX pipe. This will allow rulesets using 567238032Speter $&{client_name} to process without sending the string through 567338032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 567438032Speter A combination of deferred delivery mode, a double bounce situation, 567538032Speter and the inability to save a bounce message to 567638032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 567738032Speter to postmaster but not remove the offending envelope from the 567838032Speter queue causing it to create a new bounce message each time the 567938032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 568038032Speter Associates. 568138032Speter Remove newlines from hostname information returned via DNS. There are 568238032Speter no known security implications of newlines in hostnames as 568338032Speter sendmail filters newlines in all vital areas; however, this 568438032Speter could cause confusing error messages. 568538032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 568638032Speter rejected if any of the specified addresses were bad. This 568738032Speter behavior was modified to only reject the bad addresses and not 568838032Speter the entire message. Problem noted by Jozsef Hollosi of 568938032Speter SuperNet, Inc. 569038032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 569138032Speter Bryan Costales of InfoBeat, Inc. 569238032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 569338032Speter mailers. Problem noted by Kari E. Hurtta of the 569438032Speter Finnish Meteorological Institute. 569538032Speter An error in calculating the available space in the list of addresses 569638032Speter for logging deliveries could cause an address to be silently 569738032Speter dropped. 569838032Speter Include the initial user environment if sendmail is restarted via 569938032Speter a HUP signal. This will give room for the process title. 570038032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 570138032Speter Mail could be delivered without a body if the machine does not 570238032Speter support flock locking and runs out of processes during 570338032Speter delivery. Fix from Chuck Lever of the University of Michigan. 570438032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 570538032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 570638032Speter Institute. 570738032Speter Make sure non-rebuildable database maps are opened before the 570864562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 570938032Speter are needed for verifying the left hand side of the aliases. 571038032Speter Problem noted by Lloyd Parkes of Victoria University. 571138032Speter Make sure sender RFC822 source route addresses are alias expanded for 571238032Speter bounce messages. Problem noted by Juergen Georgi of 571338032Speter RUS University of Stuttgart. 571438032Speter Minor lint fixes. 571538032Speter Return a temporary error instead of a permanent error if an LDAP map 571638032Speter search returns an error. This will allow sequenced maps which 571738032Speter use other LDAP servers to be checked. Fix from Booker Bense 571838032Speter of Stanford University. 571938032Speter When automatically converting from quoted printable to 8bit text do 572038032Speter not pad bare linefeeds with a space. Problem noted by Theo 572138032Speter Nolte of the University of Technology Aachen, Germany. 572238032Speter Portability: 572338032Speter Non-standard C compilers may have had a problem compiling 572438032Speter conf.c due to a standard C external declaration of 572538032Speter setproctitle(). Problem noted by Ted Roberts of 572638032Speter Electronic Data Systems. 572738032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 572838032Speter Jagielski of jaguNET Access Services. 572938032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 573038032Speter Digital UNIX: Digital UNIX (and possibly others) moves 573138032Speter loader environment variables into the loader memory 573238032Speter area. If one of these environment variables (such as 573338032Speter LD_LIBRARY_PATH) was the last environment variable, 573438032Speter an invalid memory address would be used by the process 573538032Speter title routine causing memory corruption. Problem 573638032Speter noted by Sam Hartman of Mesa Internet Systems. 573738032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 573838032Speter chownsafe() to always return 0 even if the OS does 573938032Speter not permit file giveaways. Problem noted by 574038032Speter Yasutaka Sumi of The University of Tokyo. 574164562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 574238032Speter Gerald Rinske of Siemens Business Services VAS. 574338032Speter Linux: Pad process title with NULLs. Problem noted by 574438032Speter Jon Lewis of Florida Digital Turnpike. 574538032Speter SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an 574638032Speter incorrect value for the number of interfaces. 574738032Speter Problem noted by Chris Loelke of JetStream Internet 574838032Speter Services. 574938032Speter SINIX: Update for Makefile and syslog buffer size from Gerald 575038032Speter Rinske of Siemens Business Services VAS. 575138032Speter Solaris: Make sure HASGETUSERSHELL setting for SunOS is not 575238032Speter used on a Solaris machine. Problem noted by 575338032Speter Stephen Ma of Jtec Pty Limited. 575438032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 575538032Speter Services VAS. 575638032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 575738032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 575838032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 575938032Speter Ericsson. 576038032Speter 576164562Sgshapiro8.8.7/8.8.7 1997/08/03 576238032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 576338032Speter an exclusive lock already set -- i.e., almost all systems 576438032Speter except 4.4-BSD derived systems), the initial attempt at 576538032Speter rebuilding aliases file if the database didn't already 576638032Speter exist would fail. Patch from Raymund Will of LST Software 576738032Speter GmbH. 576838032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 576938032Speter Problem noted by Fredrik J�nsson of the Royal Institute 577038032Speter of Technology, Stockholm. 577138032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 577238032Speter some environments could give "multiple definitions" for these 577338032Speter routines during compilation. If using TCP Wrappers, assume 577438032Speter that these routines are included as though they were in the 577538032Speter C library. Patch from Robert La Ferla. 577638032Speter When a NEWDB database map was rebuilt at the same time it was being 577738032Speter used by a queue run, the maps could be left locked for the 577838032Speter duration of the queue run, causing other processes to hang. 577938032Speter Problem noted by Kendall Libby of Shore.NET. 578038032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 578138032Speter mail was passed on without any recipient header. This could 578238032Speter cause problems downstream. Problem noted by Xander Jansen 578338032Speter of SURFnet ExpertiseCentrum. 578438032Speter Give error when GDBM is used with sendmail. GDBM's locking and 578538032Speter linking of the .dir and .pag files interferes with sendmail's 578638032Speter locking and security checks. Problems noted by Fyodor 578738032Speter Yarochkin of the Kyrgyz Republic FreeNet. 578838032Speter Don't fsync qf files if SuperSafe option is not set. 578938032Speter Avoid extra calls to gethostbyname for addresses for which a 579038032Speter gethostbyaddr found no value. Also, ignore any returns 579138032Speter from gethostbyaddr that look like a dotted quad. 579238032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 579338032Speter "may be forged", since at the network level we pretty much 579438032Speter have to assume that the information is good. 579538032Speter In some cases, errors during an SMTP session could leave files 579638032Speter open or locked. 579738032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 579890792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 579938032Speter errors during testing. 580038032Speter Errors in file locking of NEWDB maps had the incorrect file name 580138032Speter printed in the error message. 580238032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 580338032Speter missing parameter were issued, the EHLO behaved like a HELO. 580438032Speter Load limiting never kicked in for incoming SMTP transactions if the 580543730Speter DeliveryMode=background and any recipient was an alias or 580638032Speter had a .forward file. From Nik Conwell of Boston University. 580738032Speter On some non-Posix systems, the decision of whether chown(2) permits 580838032Speter file giveaway was undefined. From Tetsu Ushijima of the 580938032Speter Tokyo Institute of Technology. 581038032Speter Fix race condition that could cause the body of a message to be 581138032Speter lost (so only the header was delivered). This only occurs 581238032Speter on systems that do not use flock(2), and only when a queue 581338032Speter runner runs during a critical section in another message 581438032Speter delivery. Based on a patch from Steve Schweinhart of 581538032Speter Results Computing. 581638032Speter If a qf file was found in a mail queue directory that had a problem 581738032Speter (wrong ownership, bad format, etc.) and the file name was 581838032Speter exactly MAXQFNAME bytes long, then instead of being tried 581938032Speter once, it would be tried on every queue run. Problem noted 582038032Speter by Bryan Costales of Mercury Mail. 582138032Speter If the system supports an st_gen field in the status structure, 582238032Speter include it when reporting that a file has changed after open. 582338032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 582438032Speter This out to be checked as well as reported, since it is 582538032Speter theoretically possible for an attacker to remove a file after 582638032Speter it is opened and replace it with another file that has the 582738032Speter same i-number, but some filesystems (notably AFS) return 582838032Speter garbage in this field, and hence always look like the file 582938032Speter has changed. As a practical matter this is not a security 583038032Speter problem, since the files can be neither hard nor soft links, 583138032Speter and on no filesystem (that I am aware of) is it possible to 583238032Speter have two files on the same filesystem with the same i-number 583338032Speter simultaneously. 583438032Speter Delete the root Makefile from the distribution -- it is only for 583538032Speter use internally, and does not work at customer sites. 583638032Speter Fix botch that caused the second MAIL FROM: command in a single 583738032Speter transaction to clear the entire transaction. Problem 583838032Speter noted by John Kennedy of Cal State University, Chico. 583938032Speter Work properly on machines that have _PATH_VARTMP defined without 584038032Speter a trailing slash. (And a pox on vendors that decide to 584138032Speter ignore the established conventions!) Problem noted by 584238032Speter Gregory Neil Shapiro of WPI. 584338032Speter Internal changes to make it easier to add another protocol family 584438032Speter (intended for IPv6). Patches are from John Kennedy of 584538032Speter CSU Chico. 584638032Speter In certain cases, 7->8 bit MIME decoding of Base64 text could leave 584738032Speter an extra space at the beginning of some lines. Problem 584838032Speter noted by Charles Karney of Princeton University; fix based 584938032Speter on a patch from Christophe Wolfhugel. 585038032Speter Portability: 585138032Speter Allow _PATH_VENDOR_CF to be set in Makefile for consistency 585238032Speter with the _Sendmail_ book, 2nd edition. Note that 585338032Speter the book is actually wrong: _PATH_SENDMAILCF should 585438032Speter be used instead. 585538032Speter AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow 585638032Speter of Argonne National Laboratory. 585738032Speter OpenBSD from from Paul DuBois of the University of Wisconsin. 585838032Speter RISC/os 4.0 from Paul DuBois of the University of Wisconsin. 585938032Speter SunOS: Include <memory.h> to fix warning from util.c. From 586038032Speter James Aldridge of EUnet Ltd. 586138032Speter Solaris: Change STDIR (location of status file) to /etc/mail 586238032Speter in Makefiles. 586338032Speter Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from 586438032Speter Makefiles. Use NEWDB on Linux instead. 586538032Speter NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl 586638032Speter exists but behaves differently than other OSes. 586738032Speter Add SIOCGIFNUM_IS_BROKEN compile flag to get 586838032Speter around the problem. Problem noted by Tom Moore of 586938032Speter NCR Corp. 587038032Speter HP-UX 9.x: fix compile warnings for old select API.

This makes it possible to create a root 592338032Speter owned file in an arbitrary directory by inserting the symlink 592438032Speter into a writable directory after the initial lstat(2) check 592538032Speter determined that the file did not exist. The only verified 592638032Speter example of a system having these odd semantics for O_EXCL 592738032Speter and symbolic links was HP-UX prior to version 9.07. Most 592838032Speter systems do not have the problem, since a exclusive create 592938032Speter of a file disallows symbolic links. Systems that have been 593038032Speter verified to NOT have the problem include AIX 3.x, *BSD, 593138032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 593238032Speter and Ultrix. This is a potential exposure on systems that 593338032Speter have this bug and which do not have a MAILER-DAEMON alias 593438032Speter pointing at a legitimate account, since this will cause old 593538032Speter mail to be dropped in /var/tmp/dead.letter. 593638032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 593738032Speter if maps or alias files are in world writable directories. 593838032Speter If your system has alias maps in writable directories, it 593938032Speter is potentially possible for an attacker to replace the .db 594038032Speter (or .dir and .pag) files by symbolic links pointing at 594138032Speter another database; this can be used either to expose 594238032Speter information (e.g., by pointing an alias file at /etc/spwd.db 594338032Speter and probing for accounts), or as a denial-of-service attack 594438032Speter (by trashing the password database). The fix disallows 594538032Speter symbolic links entirely when rebuilding alias files or on 594638032Speter maps that are in writable directories, and always warns on 594738032Speter writable directories; 8.9 will probably consider writable 594838032Speter directories to be fatal errors. This does not represent an 594938032Speter exposure on systems that have alias files in unwritable 595038032Speter system directories. 595138032Speter SECURITY: disallow .forward or :include: files that are links (hard 595238032Speter or soft) if the parent directory (or any directory in the 595338032Speter path) is writable by anyone other than the owner. This is 595438032Speter similar to the previous case for user files. This change 595538032Speter should not affect most systems, but is necessary to prevent 595638032Speter an attacker who can write the directory from pointing such 595738032Speter files at other files that are readable only by the owner. 595838032Speter SECURITY: Tighten safechown rules: many systems will say that they 595938032Speter have a safe (restricted to root) chown even on files that 596038032Speter are mounted from another system that allows owners to give 596138032Speter away files. The new rules are very strict, trusting file 596238032Speter ownership only in those few cases where the system has 596338032Speter been verified to be at least as paranoid as necessary. 596438032Speter However, it is possible to relax the rules to partially 596538032Speter trust the ownership if the directory path is not world or 596638032Speter group writable. This might allow someone who has a legitimate 596738032Speter :include: file (referenced directly from /etc/aliases) to 596838032Speter become another non-root user if the :include: file is in a 596938032Speter non-writable directory on an NFS-mounted filesystem where 597038032Speter the local system says that giveaway is denied but it is 597138032Speter actually permitted. I believe this to be a very small set 597238032Speter of cases. If in doubt, do not point :include: aliases at 597338032Speter NFS-mounted filesystems. 597438032Speter SECURITY: When setting a numeric group id using the RunAsUser option 597538032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 597638032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 597738032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 597838032Speter The user id was still set properly. Problem noted by Uli 597938032Speter Pralle of the Technical University of Berlin. 598038032Speter Save the initial gid set for use when checking for if the 598138032Speter PrivacyOptions=restrictmailq option is set. Problem reported 598238032Speter by Wolfgang Ley of DFN-CERT. 598338032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 598438032Speter failure on one message won't affect future messages to the 598538032Speter same host). 598638032Speter IP source route printing had an "off by one" error that would 598738032Speter affect any options that came after the route option. Patch 598838032Speter from Theo de Raadt. 598938032Speter The "Message is too large" error didn't successfully bounce the error 599038032Speter back to the sender. Problem reported by Stephen More of 599138032Speter PSI; patch from Gregory Neil Shapiro of WPI. 599238032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 599338032Speter of 5.1.3); it apparently gets used in multiple ways. 599438032Speter Suggested by John Myers of Portola Communications. 599538032Speter Fix possible extra null byte generated during collection if errors 599638032Speter occur at the beginning of the stream. Patch contributed by 599738032Speter Andrey A. Chernov and Gregory Neil Shapiro. 599838032Speter Code changes to avoid possible reentrant call of malloc/free within 599938032Speter a signal handler. Problem noted by John Beck of Sun 600038032Speter Microsystems. 600138032Speter Move map initialization to be earlier so that check_relay ruleset 600238032Speter will have the latest version of the map data. Problem noted 600338032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 600438032Speter If there are fatal errors during the collection phase (e.g., message 600538032Speter too large) don't send the bogus message. 600638032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 600738032Speter have errors and have owner- aliases. Problem noted by Michael 600838032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 600938032Speter Avoid null pointer dereference on illegal Boundary= parameters in 601038032Speter multipart/mixed Content-Type: header. Problem noted by 601138032Speter Richard Muirden of RMIT University. 601238032Speter Always print error messages during newaliases (-bi) even if the 601338032Speter ErrorMode is not set to "print". Fix from Gregory Neil 601438032Speter Shapiro. 601538032Speter Test mode could core dump if you did a /map lookup in an optional map 601638032Speter that could not be opened. Based on a fix from John Beck of 601738032Speter Sun Microsystems. 601838032Speter If DNS is misconfigured so that the last MX record tried points to 601938032Speter a host that does not have an A record, but other MX records 602038032Speter pointed to something reasonable, don't bounce the message 602138032Speter with a "host unknown" error. Note that this should really 602238032Speter be fixed in the zone file for the domain. Problem noted by 602338032Speter Joe Rhett of Navigist, Inc. 602438032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 602538032Speter the message as having been tried; otherwise the next queue 602638032Speter run will not realize that this is a second attempt and will 602738032Speter retry immediately. Problem noted by Bryan Costales of 602838032Speter Mercury Mail. 602938032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 603038032Speter will be run until the later setting of the clock is reached. 603138032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 603238032Speter Morgan Stanley. 603338032Speter If the load average rises above the cutoff threshold (above which 603438032Speter sendmail will not process the queue at all) during a queue 603538032Speter run, abort the queue run immediately. Problem noted by 603638032Speter Bryan Costales of Mercury Mail. 603738032Speter The variable queue processing algorithm (based on the message size, 603838032Speter number of recipients, message precedence, and job age) was 603938032Speter non-functional -- either the entire queue was processed or 604038032Speter none of the queue was processed. The updated algorithm 604138032Speter does no queue run if a single recipient zero size job will 604238032Speter not be run. 604338032Speter If there is a fatal ("panic") message that will cause sendmail to 604438032Speter die immediately, never hold the error message for future 604538032Speter printing. 604638032Speter Force ErrorMode=print in -bt mode so that all errors are printed 604738032Speter regardless of the setting of the ErrorMode option in the 604838032Speter configuration file. Patch from Gregory Neil Shapiro. 604938032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 605038032Speter routine available in one of the libraries. Use it in conf.h. 605138032Speter The -m (match only) flag now works on host class maps. 605238032Speter If class hash or btree maps are rebuilt, sendmail will now detect 605338032Speter this and reopen the map. Previously, they could give 605438032Speter erroneous results during a single message processing 605538032Speter (but would recover when the next message was received). 605638032Speter Don't delete zero length queue files when doing queue runs until the 605738032Speter files are at least ten minutes old. This avoids a potential 605838032Speter race condition: the creator creates the qf file, getting back 605938032Speter a file descriptor. The queue runner locks it and deletes it 606038032Speter because it is zero length. The creator then writes the 606138032Speter descriptor that is now for a disconnected file, and the 606238032Speter job goes away. Based on a suggestion by Bryan Costales. 606338032Speter When determining the "validated" host name ($_ macro), do a forward 606438032Speter (A) DNS lookup on the result of the PTR lookup and compare 606538032Speter results. If they differ or if the PTR lookup fails, tag the 606638032Speter address as "may be forged". 606738032Speter Log null connections (i.e., hosts that connect but do not do any 606838032Speter substantive activity on the connection before disconnecting; 606938032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 607038032Speter Always permit "writes" to /dev/null regardless of the link count. 607138032Speter This is safe because /dev/null is special cased, and no open 607238032Speter or write is ever actually attempted. Patch from Villy Kruse 607338032Speter of TwinCom. 607438032Speter If a message cannot be sent because of a 552 (exceeded storage 607538032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 607638032Speter was given, don't return the body in the bounce, since there 607738032Speter is a very good chance that the message will double-bounce. 607838032Speter Fix possible line truncation if a quoted-printable had an =00 escape 607938032Speter in the body. Problem noted by Charles Karney of the Princeton 608038032Speter Plasma Physics Laboratory. 608138032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 608238032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 608338032Speter Institute. 608438032Speter The MaxDaemonChildren option wasn't applying to queue runs as 608538032Speter documented. Note that this increases the potential denial 608638032Speter of service problems with this option: an attacker can 608738032Speter connect many times, and thereby lock out queue runs as well 608838032Speter as incoming connections. If you use this option, you should 608938032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 609038032Speter to avoid this attack. Failure to limit noted by Matthew 609138032Speter Dillon of BEST Internet Communications. 609238032Speter Always give a message in newaliases if alias files cannot be 609338032Speter opened instead of failing silently. Suggested by Gregory 609438032Speter Neil Shapiro. This change makes the code match the O'Reilly 609538032Speter book (2nd edition). 609638032Speter Some older versions of the resolver could return with h_errno == -1 609738032Speter if no name server could be reached, causing mail to bounce 609838032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 609938032Speter John Beck of SunSoft. 610038032Speter If a :include: file is owned by a user that does not have an entry 610138032Speter in the passwd file, sendmail could dereference a null pointer. 610238032Speter Problem noted by Satish Mynam of Sun Microsystems. 610338032Speter Take precautions to make sure that the SMTP protocol cannot get out 610438032Speter of sync if (for example) an alias file cannot be opened. 610538032Speter Fix a possible race condition that can cause a SIGALRM to come in 610638032Speter immediately after a SIGHUP, causing the new sendmail to die. 610738032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 610838032Speter from Villy Kruse of TwinCom. 610938032Speter Ignore improperly formatted SMTP reply codes. Previously these were 611038032Speter partially processed, which could cause confusing error 611138032Speter returns. 611238032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 611338032Speter on some architectures. 611438032Speter Portability: 611538032Speter A/UX: from Jim Jagielski of NASA/GSFC. 611638032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 611738032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 611838032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 611938032Speter defined. Problem reported by A Sun of the University 612038032Speter of Washington. 612138032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 612238032Speter the system rather than guessing at compile time. 612338032Speter Patch contributed by John Beck of Sun Microsystems. 612438032Speter Intel Paragon: from Wendy Lin of Purdue University. 612538032Speter GNU Hurd: from Miles Bader of the GNU project. 612638032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 612738032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 612838032Speter Unfortunately releasing them opens a race condition, 612938032Speter but there appears to be no fix for this. Patch from 613038032Speter Gregory Neil Shapiro. 613138032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 613238032Speter Solaris: a bug in strcasecmp caused characters with the 613338032Speter high order bit set to apparently randomly match 613438032Speter letters -- for example, $| (0233) matches "i" and "I". 613538032Speter Problem noted by John Gregson of the University of 613638032Speter Cambridge. 613738032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 613838032Speter Kari Hurtta. 613938032Speter IRIX 6.x: Create Makefiles for systems that claim to be 614038032Speter IRIX64 but are 6.2 or higher (so use the regular 614138032Speter IRIX Makefile). 614238032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 614338032Speter Problem noted by Eric Hagberg of Morgan Stanley. 614438032Speter CONFIG: Some canonification was still done for UUCP-like addresses 614538032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 614638032Speter Brian Candler. 614738032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 614838032Speter local names as local.

Problem noted by Gregory Neil Shapiro. 615338032Speter CONFIG: Retain "+detail" information when forwarding mail to a 615438032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 615538032Speter Guenther of Gustavus Adolphus College. 615638032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 615738032Speter rules are the same as for aliasing. Based on a patch from 615838032Speter Gregory Neil Shapiro. 615938032Speter CONFIG: Break up parsing rules into several pieces; this should 616038032Speter have no functional change in this release, but makes it 616138032Speter possible to have better anti-spam rulesets in the future. 616238032Speter CONFIG: Disallow double dots in host names to avoid having the 616338032Speter HostStatusDirectory store status under the wrong name. 616438032Speter In some cases this can be used as a denial-of-service attack. 616538032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 616638032Speter Gregory Neil Shapiro. 616738032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 616838032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 616938032Speter don't include From_, and convert to 8-bit). Suggestions 617038032Speter from Kimmo Suominen and Roderick Schertler. 617164562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 617238032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 617338032Speter was specified, even when it wasn't. 617438032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 617538032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 617638032Speter "slip in" a symbolic link between the lstat(2) call and the 617738032Speter exclusive open. This is only a problem on System V derived 617838032Speter systems that allow an exclusive create on files that are 617938032Speter symbolic links pointing nowhere. 618038032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 618138032Speter not reset back to root, which on some systems would cause 618238032Speter later mailboxes to fail. Also, any partial message would 618338032Speter not be truncated, which could result in repeated deliveries. 618438032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 618538032Speter developers). 618638032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 618738032Speter change to the sendmail map code was made in 8.8.3. Problem 618838032Speter noted by Gregory Neil Shapiro. 618938032Speter MAKEMAP: Give warnings on file problems such as map files that are 619090792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 619138032Speter often run as root and hence has the potential for the same 619238032Speter sorts of problems as alias rebuilds. 619338032Speter MAKEMAP: Change compilation so that it will link properly on 619438032Speter NEXTSTEP. 619538032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 619638032Speter Accept an optional list of arguments following the server 619738032Speter name for the ETRN arguments to use (instead of $=w).

This 620138032Speter Perl script converts GECOS information in the /etc/passwd 620238032Speter file into aliases, allowing for faster access to full name 620338032Speter lookups; it is also clever about adding aliases (to root) 620438032Speter for system accounts. 620538032Speter NEW FILES: 620638032Speter src/safefile.c 620738032Speter cf/ostype/gnuhurd.m4 620838032Speter cf/ostype/irix6.m4 620938032Speter contrib/passwd-to-alias.pl 621038032Speter src/Makefiles/Makefile.IRIX64.6.1 621138032Speter src/Makefiles/Makefile.IRIX64.6.x 621238032Speter RENAMED FILES: 621338032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 621438032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 621538032Speter 621664562Sgshapiro8.8.5/8.8.5 1997/01/21 621738032Speter SECURITY: Clear out group list during startup. Without this, sendmail 621838032Speter will continue to run with the group permissions of the caller, 621938032Speter even if RunAsUser is specified. 622038032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 622138032Speter to any known attack, but it's best to be conservative. 622238032Speter Suggested by Peter Wemm of DIALix. 622338032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 622438032Speter security implications. Patch from Alex Garthwaite of the 622538032Speter University of Pennsylvania. 622638032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 622738032Speter would truncate the address after "Full". Although the -f 622838032Speter syntax is incorrect (since it is in the envelope, it 622938032Speter shouldn't have comments and full names), the failure mode 623038032Speter was unnecessarily awful. 623138032Speter Fix a possible null pointer dereference when converting 8-bit data 623238032Speter to a 7-bit format. Problem noted by Jim Hutchins of 623338032Speter Sandia National Labs and David James of British Telecom. 623438032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 623538032Speter runs. Although this really shouldn't be used (F=9 is for 623638032Speter final delivery only, and using it on an SMTP mailer makes 623738032Speter it possible for a message to be converted from 8->7->8->7 623838032Speter bits several times), it shouldn't have failed with a syserr. 623938032Speter Problem noted by Eric Hagberg of Morgan Stanley. 624038032Speter _Really_ fix the multiple :maildrop code in the user database 624138032Speter module. Patch from Roy Mongiovi of Georgia Tech. 624238032Speter Let F lines in the configuration file actually read root-only 624338032Speter files if the configuration file is safe. Based on a 624438032Speter patch from Keith Reynolds of SCO. 624538032Speter ETRN followed by QUIT would hold the connection open until the queue 624638032Speter run completed. Problem noted by Truck Lewis of TDK 624738032Speter Semiconductor Corp. 624838032Speter It turns out that despite the documentation, the TCP wrappers library 624938032Speter does _not_ log rejected connections. Do the logging ourselves. 625038032Speter Problem noted by Fletcher Mattox of the University of Texas 625138032Speter at Austin. 625238032Speter If sendmail finds a qf file in its queue directory that is an unknown 625338032Speter version (e.g., when backing out to an old version), the 625438032Speter error is reported on every queue run. Change it to only 625538032Speter give the error once (and rename the qf => Qf). Patch from 625638032Speter William A. Gianopoulos of Raytheon Company. 625738032Speter Start a new session when doing background delivery; currently it 625838032Speter ignored signals but didn't start a new signal, that caused 625938032Speter some problems if a background process tried to send mail 626038032Speter under certain circumstances. Problem noted by Eric Hagberg 626138032Speter of Morgan Stanley; fix from Kari Hurtta. 626238032Speter Simplify test for skipping a queue run to just check if the current 626338032Speter load average is >= the queueing load average. Previously 626438032Speter the check factored in some other parameters that caused it 626538032Speter to essentially never skip the queue run. Patch from Bryan 626638032Speter Costales. 626738032Speter If the SMTP server is running in "nullserver" mode (that is, it is 626838032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 626938032Speter (25) commands; this helps prevent a bad guy from putting 627038032Speter you into a tight loop as a denial-of-service attack. Based 627138032Speter on an e-mail conversation with Brad Knowles of AOL. 627238032Speter Slow down when too many "light weight" commands have been issued; 627338032Speter this helps prevent a class of denial-of-service attacks. 627438032Speter The current values and defaults are: 627538032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 627638032Speter MAXHELOCOMMANDS 3 HELO, EHLO 627738032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 627838032Speter MAXETRNCOMMANDS 8 ETRN 627938032Speter These will probably be configurable in a future release. 628038032Speter On systems that have uid_t typedefed to be an unsigned short, programs 628138032Speter that had the F=S flag and no U= equate would be invoked with 628238032Speter the real uid set to 65535 rather than being left unchanged. 628338032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 628438032Speter by Steve Hubert of the University of Washington, Seattle. 628538032Speter Mail that was Quoted-Printable encoded and had a soft line break on 628638032Speter the last line (i.e., an incomplete continuation) had the last 628738032Speter line dropped. Since this appears to be illegal it isn't 628838032Speter clear what to do with it, but flushing the last line seems 628938032Speter to be a better "fail soft" approach. Based on a patch from 629038032Speter Eric Hagberg. 629138032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 629238032Speter bogus HELO command still causes the "Polite people say HELO 629338032Speter first" error message. Problem pointed out by Chris Thomas 629438032Speter of UCLA; patch from John Beck of SunSoft. 629538032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 629671345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 629771345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 629871345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 629938032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 630038032Speter in a DATA transaction to be sticky; these can occur because 630138032Speter a message is too large, and smaller messages should still go 630238032Speter through. Problem noted by Matt Dillon of Best Internet 630338032Speter Communications. 630438032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 630538032Speter had been successfully delivered to the envelope sender. 630638032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 630738032Speter Gregory Neil Shapiro of WPI. 630838032Speter Give better diagnostics on long alias lines. Based on code contributed 630938032Speter by Patrick Gosling of the University of Cambridge. 631038032Speter Increase the number of virtual interfaces that will be probed for 631138032Speter alternate names. Problem noted by Amy Rich of Shore.Net. 631238032Speter PORTABILITY: 631338032Speter UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from 631438032Speter Toshiaki Nomura of Fujitsu Limited. 631538032Speter SunOS with LDAP support: compile problems with struct timeval. 631638032Speter Patch from Nick Cuccia of TCSI Corporation. 631738032Speter SCO: from Keith Reynolds of SCO. 631838032Speter Solaris: kstat load average computation wasn't being used. 631938032Speter Fixes from Michael Ju. Tokarev of Telecom Service, JSC 632038032Speter (Moscow). 632138032Speter OpenBSD: from Jason Downs of teeny.org. 632238032Speter Altos System V: from Tim Rice. 632338032Speter Solaris 2.5: from Alan Perry of SunSoft. 632438032Speter Solaris 2.6: from John Beck of SunSoft. 632538032Speter Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli 632638032Speter of Pratt & Whitney <miorelli@pweh.com>. 632738032Speter CONFIG: It seems that I hadn't gotten the Received: line syntax 632838032Speter _just_right_ yet. Tweak it again. I'll omit the names 632938032Speter of the "contributors" (quantity two) in this one case. 633038032Speter As of now, NO MORE DISCUSSION about the syntax of the 633138032Speter Received: line. 633238032Speter CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E), 633338032Speter it never inserts that class into the output file. Fix it 633438032Speter so it will honor EXPOSED_USER but will _not_ include root 633538032Speter automatically in this class. Problem noted by Ronan KERYELL 633638032Speter of Centre de Recherche en Informatique de l'�cole Nationale 633738032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 633838032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 633938032Speter such as LUSER_RELAY. This change permits the following 634038032Speter syntaxes: ``local:'' will send to the same user on the 634138032Speter local machine (e.g., in a mailertable entry for "host", 634238032Speter ``local:'' will cause an address addressed to user@host to 634338032Speter go to user on the local machone). ``local:user'' will send 634438032Speter to the named user on the local machine. ``local:user@host'' 634538032Speter is equivalent to ``local:user'' (the host is ignored). In 634638032Speter all cases, the original user@host is passed in $@ (i.e., the 634738032Speter detail information). Inspired by a report from Michael Fuhr. 634838032Speter CONFIG: Strip quotes from the first word of an "error:" host 634938032Speter indication. This lets you set (for example) the LUSER_RELAY 635038032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 635138032Speter of the \" so that the resulting string is properly quoted. 635238032Speter Problem noted by Gregory Neil Shapiro of WPI. 635338032Speter OP.ME: documentation was inconsistent about whether sendmail did a 635438032Speter NOOP or a RSET to probe the connection (it does a RSET). 635538032Speter Inconsistency noted by Deeran Peethamparam. 635638032Speter OP.ME: insert additional blank pages so it will print properly on 635738032Speter a duplex printer. From Matthew Black of Cal State University, 635838032Speter Long Beach. 635938032Speter 636064562Sgshapiro8.8.4/8.8.4 1996/12/02 636138032Speter SECURITY: under some circumstances, an attacker could get additional 636238032Speter permissions by hard linking to files that were group 636338032Speter writable by the attacker. The solution is to disallow any 636438032Speter files that have hard links -- this will affect .forward, 636538032Speter :include:, and output files. Problem noted by Terry 636638032Speter Kyriacopoulos of Interlog Internet Services. As a 636738032Speter workaround, set UnsafeGroupWrites -- always a good idea. 636838032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 636938032Speter is, it is possible to do a denial-of-service attack on 637038032Speter MX hosts that rely on the use of the null MX list. There 637138032Speter is no danger if you have this option turned off (the default). 637238032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 637338032Speter unsafe. I know of no specific attack against this, although 637438032Speter a denial-of-service attack is probably possible, but in theory 637538032Speter you should not be able to safely tweak anything that affects 637638032Speter the permissions that are used when mail is delivered. 637738032Speter Purgestat could go into an infinite loop if one of the host status 637838032Speter directories somehow became empty. Problem noted by Roy 637938032Speter Mongiovi of Georgia Tech. 638038032Speter Processes got "lost" when counting children due to a race condition. 638138032Speter This caused "proc_list_probe: lost pid" messages to be logged. 638238032Speter Problem noted by several people. 638338032Speter On systems with System V SIGCLD child signal semantics (notably AIX 638438032Speter and HP-UX), mail transactions would print the message "451 638538032Speter SMTP-MAIL: lost child: No child processes". Problem noted 638638032Speter by several people. 638738032Speter Miscellaneous compiler warnings on picky compilers (or when setting 638838032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 638938032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 639038032Speter not be persistent between runs, since they are based on the 639138032Speter message rather than the host. Problem noted by Matt Dillon 639238032Speter of Best Internet Communications. 639338032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 639438032Speter of NCR (a.k.a., AT&T Global Information Solutions). 639538032Speter Avoid the possibility of having a child daemon run to completion 639638032Speter (including closing the SMTP socket) before the parent has 639738032Speter had a chance to close the socket; this can cause the parent 639838032Speter to hang for a long time waiting for the socket to drain. 639938032Speter Patch from Don Lewis of TDK Semiconductor. 640038032Speter If the fork() failed in a queue run, the queue runners would not be 640138032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 640238032Speter Some error conditions in ETRN could cause output without an SMTP 640338032Speter status code. Problem noted by Don Lewis. 640438032Speter Multiple :maildrop addresses in the user database didn't work properly. 640538032Speter Patch from Roy Mongiovi of Georgia Tech. 640638032Speter Add ".db" automatically onto any user database spec that does not 640738032Speter already have it; this is for consistency with makemap, the 640838032Speter K line, and the documentation. Inconsistency pointed out 640938032Speter by Roy Mongiovi. 641038032Speter Allow sendmail to be properly called in nohup mode. Patch from 641138032Speter Kyle Jones of UUNET. 641238032Speter Change ETRN to ignore but still update host status files; previously 641338032Speter it would ignore them and not save the updated status, which 641438032Speter caused stale information to be maintained. Based on a patch 641538032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 641638032Speter ETRN ignore the MinQueueAge option. 641738032Speter Patch long term host status to recover more gracefully from an empty 641838032Speter host status file condition. Patch from NAKAMURA Motonori 641938032Speter of Kyoto University. 642038032Speter Several patches to signal handling code to fix potential race 642138032Speter conditions from Don Lewis. 642238032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 642338032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 642438032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 642538032Speter compile flag; use NETINET instead. Solution based on a 642638032Speter patch from Bryan Costales. 642738032Speter PORTABILITY FIXES: 642838032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 642938032Speter /etc/security/passwd file when called as root. This 643038032Speter is very slow on some systems. To speed it up, use the 643138032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 643238032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 643338032Speter SCO 5.x: include -lprot in the Makefile. Patch from Bill 643438032Speter Glicker of Burrelle's Information Service. 643538032Speter NEWS-OS 4.x: need a definition for MODE_T to compile. Patch 643638032Speter from Makoto MATSUSHITA of Osaka University. 643738032Speter SunOS 4.0.3: compile problems. Patches from Andrew Cole of 643838032Speter Leeds University and SASABE Tetsuro of the University 643938032Speter of Tokyo. 644038032Speter DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support 644138032Speter Services, Inc. 644238032Speter Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp. 644338032Speter I believe this to have only been a problem if you 644438032Speter compiled with -DUSE_VENDOR_CF_PATH -- another reason 644538032Speter to stick with /etc/sendmail.cf as your One True Path. 644638032Speter Digital UNIX (OSF/1 on Alpha) load average computation from 644738032Speter Martin Laubach of the Technischen Universit�t Wien. 644838032Speter CONFIG: change default Received: line to be multiple lines rather 644938032Speter than one long one. By popular demand. 645038032Speter MAIL.LOCAL: warnings weren't being logged on some systems. Patch 645138032Speter from Jerome Berkman of U.C. Berkeley. 645238032Speter MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs 645338032Speter to take a very long time. Problem noted by Yoshiro YONEYA 645438032Speter of NTT Software Corporation. 645538032Speter CONTRIB: add etrn.pl, contributed by John Beck. 645638032Speter NEW FILES: 645738032Speter contrib/etrn.pl 645838032Speter 645964562Sgshapiro8.8.3/8.8.3 1996/11/17 646038032Speter SECURITY: it was possible to get a root shell by lying to sendmail 646138032Speter about argv[0] and then sending it a signal. Problem noted 646238032Speter by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the 646338032Speter best-of-security list. 646438032Speter Log sendmail binary version number in "Warning: .cf version level 646538032Speter (%d) exceeds program functionality (%d) message" -- this 646638032Speter should make it clearer to people that they are running 646738032Speter the wrong binary. 646838032Speter Fix a problem that occurs when you open an SMTP connection and then 646938032Speter do one or more ETRN commands followed by a MAIL command; at 647038032Speter the end of the DATA phase sendmail would incorrectly report 647138032Speter "451 SMTP-MAIL: lost child: No child processes". Problem 647238032Speter noted by Eric Bishop of Virginia Tech. 647338032Speter When doing text-based host canonification (typically /etc/hosts 647438032Speter lookup), a null host name would match any /etc/hosts entry 647538032Speter with space at the end of the line. Problem noted by Steve 647638032Speter Hubert of the University of Washington, Seattle. 647738032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 647838032Speter Problem reported by Tom Smith of Digital Equipment Corp. 647938032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 648038032Speter size PACKETSZ (512) is not sufficient for some nameserver 648138032Speter answers containing very many resource records. The resolver 648238032Speter may also switch to TCP and retry if it detects UDP packet 648338032Speter overflow. Also, allow for the fact that the resolver 648438032Speter routines res_query and res_search return the size of the 648538032Speter *un*truncated answer in case the supplied answer buffer it 648638032Speter not big enough to accommodate the entire answer. Patch from 648738032Speter Eric Wassenaar. 648838032Speter Improvements to MaxDaemonChildren code. If you think you have too 648938032Speter many children, probe the ones you have to verify that they 649038032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 649138032Speter Also, do this probe before growing the vector of children 649238032Speter pids; this previously caused the vector to grow indefinitely 649338032Speter due to a race condition. Problem reported by Kyle Jones of 649438032Speter UUNET. 649538032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 649638032Speter O_EXLOCK to zero; this fools the map compilation code into 649738032Speter thinking that it can avoid race conditions by locking on open. 649838032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 649938032Speter Leif Erlingsson of Data Lege. 650038032Speter Always call res_init() on startup (if compiled in, of course) to 650138032Speter allow the sendmail.cf file to tweak resolver flags; without 650238032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 650338032Speter Andrew Sun of Merrill Lynch. 650438032Speter Improvements to host status printing code. Suggested by Steve Hubert 650538032Speter of the University of Washington, Seattle. 650638032Speter Change MinQueueAge option processing to do the check for the job age 650738032Speter when reading the queue file, rather than at the end; this 650838032Speter avoids parsing the addresses, which can do DNS lookups. 650938032Speter Problem noted by John Beck of InReference, Inc. 651038032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 651138032Speter properly escaped. Problem noted by Peter Nilsson of the 651238032Speter University of Linkoping. 651338032Speter In some cases, sendmail would retain root permissions during queue 651438032Speter runs even if RunAsUser was set. Problem noted by Mark 651538032Speter Thomas of Mark G. Thomas Consulting. 651638032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 651738032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 651838032Speter the envelope, and the receiving SMTP server speaks DSN, then 651938032Speter the DSN would be both generated locally and propagated to the 652038032Speter other end. 652138032Speter The U= mailer field didn't correctly extract the group id if the 652238032Speter user id was numeric. Problem noted by Kenneth Herron of 652338032Speter MCI Telecommunications Communications. 652438032Speter If a message exceeded the fixed maximum size on input, the body of 652538032Speter the message was included in the bounce. Note that this did 652638032Speter not occur if it exceeded the maximum _output_ size. Problem 652738032Speter reported by Kyle Jones of UUNET. 652838032Speter PORTABILITY FIXES: 652938032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 653038032Speter AIX4 defines to use seteuid(2) instead, which 653138032Speter works on 4.1 as well as 4.2. Problem noted by 653238032Speter H�kan Lindholm of interAF, Sweden. 653338032Speter AIX4: use tzname[] vector to determine time zone name. 653438032Speter Patch from NAKAMURA Motonori of Kyoto University. 653538032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 653638032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 653738032Speter Solaris: kstat(3k) support for retrieving the load average. 653838032Speter This adds the LA_KSTAT definition for LA_TYPE. 653938032Speter The outline of the implementation was contributed 654038032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 654138032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 654238032Speter declaration of struct rusage at the top of conf.h; 654338032Speter change it to only be included if you are using gcc, 654438032Speter which is apparently the only compiler that requires 654538032Speter it in the first place. Problem noted by Jeff 654638032Speter Earickson of Colby College. 654738032Speter IRIX: don't default to using gcc. IRIX is a civilized 654838032Speter operating system that comes with a decent compiler 654938032Speter by default. Problem noted by Barry Bouwsma and 655038032Speter Kari Hurtta. 655138032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 655238032Speter consistency with other local mailers. Inconsistency 655338032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 655438032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 655538032Speter overhead) as part of the bestmx_is_local feature, the 655638032Speter domain part was dropped from the name. Patch from Steve 655738032Speter Hubert of the University of Washington, Seattle. 655838032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 655938032Speter end up being translated to the null host name, which would 656038032Speter return any entry in /etc/hosts that had a space at the end 656138032Speter of the line. Problem noted by Steve Hubert of the 656238032Speter University of Washington, Seattle. 656338032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 656438032Speter Polytechnic Institute. 656538032Speter MAKEMAP: tweak hash and btree parameters for better performance. 656638032Speter Patch from Matt Dillon of Best Internet Communications. 656738032Speter NEW FILES: 656838032Speter src/Makefiles/Makefile.Linux.ppc 656938032Speter cf/ostype/aix4.m4 657038032Speter cf/ostype/mklinux.m4 657138032Speter 657264562Sgshapiro8.8.2/8.8.2 1996/10/18 657338032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 657438032Speter changed the code but didn't fix the problem. 657538032Speter PORTABILITY FIXES: 657638032Speter Solaris: Don't use the system getusershell(3); it can 657738032Speter apparently corrupt the heap in some circumstances. 657838032Speter Problem found by Ken Pizzini of Spry, Inc. 657938032Speter OP.ME: document several mailer flags that were accidentally omitted 658038032Speter from this document.

Problem noted 658638032Speter by Dan Bernstein of the University of Illinois at Chicago. 658738032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 658838032Speter message could overflow a buffer if it was converted back 658938032Speter to 8 bits. This caused core dumps and has the potential 659038032Speter for a remote attack. Problem first noted by Gregory Shapiro 659138032Speter of WPI. 659238032Speter Avoid duplicate deliveries of error messages on systems that don't 659338032Speter have flock(2) support. Patch from Motonori Nakamura of 659438032Speter Kyoto University. 659538032Speter Ignore null FallBackMX (V) options. If this option is null (as 659638032Speter opposed to undefined) it can cause "null signature" syserrs 659738032Speter on illegal host names. 659838032Speter If a Base64 encoded text/plain message has no trailing newline in 659938032Speter the encoded text, conversion back to 8 bits will drop the 660038032Speter final line. Problem noted by Pierre David. 660138032Speter If running with a RunAsUser, sendmail would give bogus "cannot 660238032Speter setuid" (or seteuid, or setreuid) messages on some systems. 660338032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 660438032Speter Always print error messages in -bv mode -- previously, -bv would 660538032Speter be absolutely silent on errors if the error mode was sent 660638032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 660738032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 660838032Speter term host status. This is necessary because it is common 660938032Speter to do this when you know a host has just come back up. 661038032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 661138032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 661238032Speter University of Leicester. 661338032Speter If a service (such as NIS) is specified as the last entry in the 661438032Speter service switch, but that service is not compiled in, sendmail 661538032Speter would return a temporary failure when an entry was not found 661638032Speter in the map. This caused the message to be queued instead of 661738032Speter bouncing immediately. Problem noted by Harry Edmon of the 661838032Speter University of Washington. 661938032Speter PORTABILITY FIXES: 662038032Speter Solaris 2.3 had compilation problems in conf.c. Several 662138032Speter people pointed this out. 662238032Speter NetBSD from Charles Hannum of MIT. 662338032Speter AIX4 improvements based on info from Steve Bauer of South 662438032Speter Dakota School of Mines & Technology. 662538032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 662638032Speter Patch from Gil Kloepfer Jr. 662738032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 662838032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 662938032Speter were also in $=w. Problem noted by Zoltan Basti of 663038032Speter Softec. 663138032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 663238032Speter on a patch from Eric Hagberg of Morgan Stanley. 663338032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 663438032Speter of Stanford via Robert La Ferla. 663538032Speter 663664562Sgshapiro8.8.0/8.8.0 1996/09/26 663738032Speter Under some circumstances, Bcc: headers would not be properly 663838032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 663938032Speter Log a warning if the sendmail daemon is invoked without a full 664038032Speter pathname, which prevents "kill -1" from working. I was 664138032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 664238032Speter Fix small buffer overflow. Since the data in this buffer was not 664338032Speter read externally, there was no security problem (and in fact 664438032Speter probably wouldn't really overflow on most compilers). Pointed 664538032Speter out by KIZU takashi of Osaka University. 664638032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 664738032Speter if a FallbackMXHost was specified in the configuration file 664838032Speter -- all mail would be sent to the fallback even if the original 664938032Speter host was accessible. Pointed out by Munenari Hirayama of 665038032Speter NSC (Japan). 665138032Speter A message that didn't terminate with a newline would (sometimes) not 665238032Speter have the trailing "." added properly in the SMTP dialogue, 665338032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 665438032Speter The DaemonPortOptions suboption to bind to a particular address was 665538032Speter incorrect and nonfunctional due to a misunderstanding of the 665638032Speter semantics of binding on a passive socket. Patch from 665738032Speter NIIBE Yutaka of Mitsubishi Research Institute. 665838032Speter Increase the number of MX hosts for a single name to 100 to better 665938032Speter handle the truly huge service providers such as AOL, which 666038032Speter has 13 at the moment (and climbing). In order to avoid 666138032Speter trashing memory, the buffer for all names has only been 666238032Speter slightly increased in size, to 12.8K from 10.2K -- this means 666338032Speter that if a single name had 100 MX records, the average size 666438032Speter of those records could not exceed 128 bytes. Requested by 666538032Speter Brad Knowles of America On Line. 666638032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 666738032Speter Urged by Dan Bernstein of U.C. Berkeley. 666838032Speter Print q_statdate and q_specificity in address structure debugging 666938032Speter printout. 667038032Speter Expand MCI structure flag bits for debugging output. 667138032Speter Support IPv6-style domain literals, which can have colons between 667238032Speter square braces. 667338032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 667438032Speter this is an attempt to track down a bug that one person seems 667538032Speter to be having (it may be a Solaris bug!). 667638032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 667738032Speter this caused the NOTIFY info to sometimes be lost. Problem 667838032Speter pointed out by Claus Assmann of the 667938032Speter Christian-Albrechts-University of Kiel. 668038032Speter The statistics gathered in the sendmail.st file were too high; in 668138032Speter some cases failures (e.g., user unknown or temporary failure) 668238032Speter would count as a delivery as far as the statistics were 668338032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 668438032Speter Systems that don't have flock() would not send split envelopes in 668538032Speter the initial run. Problem pointed out by Leonard Zubkoff of 668638032Speter Dandelion Digital. 668738032Speter Move buffer overflow checking -- these primarily involve distrusting 668838032Speter results that may come from NIS and DNS. 668938032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 669038032Speter include <paths.h> and hence had the wrong pathnames for a few 669138032Speter things like /var/tmp. Reported by Matthew Green. 669238032Speter Conditions were reversed for the Priority: header, resulting in all 669338032Speter values being interpreted as non-urgent except for non-urgent, 669438032Speter which was interpreted as normal. Patch from Bryan Costales. 669538032Speter The -o (optional) flag was being ignored on hash and btree maps 669638032Speter since 8.7.2. Fix from Bryan Costales. 669738032Speter Content-Types listed in class "q" will always be encoded as 669838032Speter Quoted-Printable (or more accurately, will never be encoded 669938032Speter as base64). The class can have primary types (e.g., "text") 670038032Speter or full types (e.g., "text/plain"). Based on a suggestion by 670138032Speter Marius Olafsson of the University of Iceland. 670238032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 670338032Speter dialogue) so it can be passed to programs in mailers. 670438032Speter Define ${bodytype} to be the body type (from the -B flag or the 670538032Speter BODY= ESMTP parameter) so it can be passed to programs in 670638032Speter mailers. 670738032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 670838032Speter flag is set in the mailer descriptor. Suggested by John 670938032Speter Myers of CMU. 671038032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 671138032Speter The command takes a host name; data for that host is 671238032Speter immediately (and asynchronously) flushed. Because this shares 671338032Speter the -qR implementation, other hosts may be attempted, but 671438032Speter there should be no security implications. Implementation 671538032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 671638032Speter Add three new command line flags to pass in DSN parameters: -V envid 671738032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 671838032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 671938032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 672038032Speter that the -N flag applies to all recipients; there is no way 672138032Speter to specify per-address notifications on the command line, 672238032Speter nor is there an equivalent for the ORCPT= per-address 672338032Speter parameter. 672438032Speter Restore LogLevel option to be safe (it can only be increased); 672538032Speter apparently I went into paranoid mode between 8.6 and 8.7 672638032Speter and made it unsafe. Pointed out by Dabe Murphy of the 672738032Speter University of Maryland. 672838032Speter New logging on log level 15: all SMTP traffic. Patches from 672938032Speter Andrew Gross of San Diego Supercomputer Center. 673038032Speter NetInfo property value searching code wasn't stopping when it found 673138032Speter a match. This was causing the wrong values to be found (and 673238032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 673338032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 673438032Speter out by Bill Wisner of Electronics for Imaging that you can't 673538032Speter use the bracket address form for the MAIL_HUB macro, since 673638032Speter that causes the brackets to remain in the envelope recipient 673738032Speter address used for delivery. The simple fix (stripping off the 673838032Speter brackets in the config file) breaks the use of IP literal 673938032Speter addresses. This flag will solve that problem. 674038032Speter Add MustQuoteChars option. This is a list of characters that must 674138032Speter be quoted if they are found in the phrase part of an address 674238032Speter (that is, the full name part). The characters @,;:\()[] are 674338032Speter always in this list and cannot be removed. The default is 674438032Speter this list plus . and ' to match RFC 822. 674538032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 674638032Speter that do not include a host name for back compatibility with 674738032Speter some stupid SMTP clients. Setting this violates RFC 1123 674838032Speter section 5.2.5. 674938032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 675038032Speter rejecting connections if it has more than this many 675138032Speter outstanding children accepting mail. Note that you may 675238032Speter see more processes than this because of outgoing mail; this 675338032Speter is for incoming connections only. 675438032Speter Add ConnectionRateThrottle option. If set to a positive value, the 675538032Speter number of incoming SMTP connections that will be permitted 675638032Speter in a single second is limited to this number. Connections are 675738032Speter not refused during this time, just deferred. The intent is to 675838032Speter flatten out demand so that load average limiting can kick in. 675938032Speter It is less radical than MaxDaemonChildren, which will stop 676038032Speter accepting connections even if all the connections are idle 676138032Speter (e.g., due to connection caching). 676238032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 676338032Speter specifies how long cached information about the state of a 676438032Speter host will be kept before they are considered stale and the 676538032Speter host is retried. If you are using persistent host status 676638032Speter (i.e., the HostStatusDirectory option is set) this will apply 676738032Speter between runs; otherwise, it applies only within a single queue 676838032Speter run and hence is useful only for hosts that have large queues 676938032Speter that take a very long time to run. 677038032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 677138032Speter into being a single line even if they had newlines in them 677238032Speter when read. This is to get around a botch in Lotus Notes. 677338032Speter Text class maps were totally broken -- if you ever retrieved the last 677438032Speter item in a table it would be truncated. Problem noted by 677538032Speter Gregory Neil Shapiro of WPI. 677638032Speter Extend the lines printed by the mailq command (== the -bp flag) when 677738032Speter -v is given to 120 characters; this allows more information 677838032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 677938032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 678038032Speter this was treated as end-of-input. Problem noted by Bryan 678138032Speter Costales. 678238032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 678338032Speter to the queue file. Fix from John Hughes of Atlantic 678438032Speter Technologies, Inc. 678538032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 678638032Speter if this happens in a queue run it can cause nasty delays. 678738032Speter Problem noted by Mark Horton of AT&T. 678838032Speter If userdb entries pointed to userdb entries, and there were multiple 678938032Speter values for a given key, the database cursor would get 679038032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 679138032Speter of Georgia Tech. Fixed by reading all the values and creating 679238032Speter a comma-separated list; thus, the -v output will be somewhat 679338032Speter different for this case. 679438032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 679538032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 679638032Speter of Stanford University. 679738032Speter When envelopes were split due to aliases with owner- aliases, and 679838032Speter there was some error on one of the lists, more than one of 679938032Speter the owners would get the message. Problem pointed out by 680038032Speter Roy Mongiovi of Georgia Tech. 680138032Speter Detect excessive recursion in macro expansions, e.g., $X defined 680238032Speter in terms of $Y which is defined in terms of $X. Problem 680338032Speter noted by Bryan Costales; patch from Eric Wassenaar. 680438032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 680538032Speter some cases get trashed causing bogus From_ lines. Fix from 680638032Speter Kyle Jones of UUNET. 680738032Speter When doing load average initialization, if the nlist call for avenrun 680838032Speter failed, the second and subsequent lookups wouldn't notice 680938032Speter that fact causing bogus load averages to be returned. Noted 681038032Speter by Casper Dik of Sun Holland. 681138032Speter Fix problem with incompatibility with some versions of inet_aton that 681238032Speter have changed the return value to unsigned, so a check for an 681338032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 681438032Speter This could cause mail to addresses such as [foo.com] to bounce 681538032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 681638032Speter Pasteur Institute. 681738032Speter DSNs were inconsistent if a failure occurred during the DATA phase 681838032Speter rather than the RCPT phase: the Action: would be correct, but 681938032Speter the detailed status information would be wrong. Problem noted 682038032Speter by Bob Snyder of General Electric Company. 682138032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 682238032Speter that this is the initial MUA->MTA submission. The flag current 682338032Speter does nothing, but in future releases (when MUAs start using 682438032Speter these flags) it will probably turn on things like DNS 682538032Speter canonification. 682638032Speter Default end-of-line string (E= specification on mailer [M] lines) 682738032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 682838032Speter mailers. 682938032Speter Change the internal definition for the *file* and *include* mailers 683038032Speter to have $u in the argument vectors so that they aren't 683138032Speter misinterpreted as SMTP mailers and thus use \r\n line 683238032Speter termination. This will affect anyone who has redefined 683338032Speter either of these in their configuration file. 683438032Speter Don't assume that IDENT servers close the connection after a query; 683538032Speter responses can be newline terminated. From Terry Kennedy of 683638032Speter St. Peter's College. 683738032Speter Avoid core dumps on erroneous configuration files that have 683838032Speter $#mailer with nothing following. From Bryan Costales. 683938032Speter Avoid null pointer dereference with high debug values in unlockqueue. 684038032Speter Fix from Randy Martin of Clemson University. 684138032Speter Fix possible buffer overrun when expanding very large macros. Fix 684238032Speter from Kyle Jones of UUNET. 684338032Speter After 25 EXPN or VRFY commands, start pausing for a second before 684438032Speter processing each one. This avoids a certain form of denial 684538032Speter of service attack. Potential attack pointed out by Bryan 684638032Speter Costales. 684738032Speter Allow new named (not numbered!) config file rules to do validity 684838032Speter checking on SMTP arguments: check_mail for MAIL commands and 684938032Speter check_rcpt for RCPT commands. These rulesets can do anything 685038032Speter they want; their result is ignored unless they resolve to the 685138032Speter $#error mailer, in which case the indicated message is printed 685238032Speter and the command is rejected. Similarly, the check_compat 685338032Speter ruleset is called before delivery with "from_addr $| to_addr" 685438032Speter (the $| is a meta-symbol used to separate the two addresses); 685538032Speter it can give a "this sender can't send to this recipient" 685638032Speter notification. Note that this patch allows $| to stand alone 685738032Speter in rulesets. 685838032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 685938032Speter that have the name, IP address, and port number (respectively) 686038032Speter of the SMTP client (that is, the entity at the other end of 686138032Speter the connection. These can be used in (e.g.) check_rcpt to 686238032Speter verify that someone isn't trying to relay mail through your 686338032Speter host inappropriately. Be sure to use the deferred evaluation 686438032Speter form, for example $&{client_name}, to avoid having these bound 686538032Speter when sendmail reads the configuration file. 686638032Speter Add new config file rule check_relay to check the incoming connection 686738032Speter information. Like check_compat, it is passed the host name 686838032Speter and host address separated by $| and can reject connections 686938032Speter on that basis. 687038032Speter Allow IDA-style recursive function calls. Code contributed by Mark 687138032Speter Lovell and Paul Vixie. 687238032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 687338032Speter a virtual UUCP address using either a domain address or the $k 687438032Speter macro. Based on code contributed by Mark Lovell and Paul 687538032Speter Vixie. 687638032Speter Add Stanford LDAP map. Requires special libraries that are not 687738032Speter included with sendmail. Contributed by Booker C. Bense 687838032Speter <bbense@networking.stanford.edu>; contact him for support. 687938032Speter See also the src/READ_ME file. 688038032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 688138032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 688238032Speter only for debugging deep bits of code where it is important to 688338032Speter distinguish between the single-character metasymbol $+ and the 688438032Speter two characters $, +. 688538032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 688638032Speter debug_dumpstate. 688738032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 688838032Speter files that are group writable are considered "unsafe" -- that 688938032Speter is, programs and files referenced from such files are not 689038032Speter valid recipients. 689138032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 689238032Speter name that was not in DNS or was a domain-literal. Problem 689338032Speter noted by Tom May. 689438032Speter Change the introduction to error messages to more clearly delineate 689538032Speter permanent from temporary failures; if both existed in a 689638032Speter single message it could be confusing. Suggested by John 689738032Speter Beck of InReference, Inc. 689838032Speter The IngoreDot (i) option didn't work for lines that were terminated 689938032Speter with CRLF. Problem noted by Ted Stockwell of Secure 690038032Speter Computing Corporation. 690138032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 690238032Speter message headers. Problem reported by Matt Dillon of Best 690338032Speter Internet Communications. 690438032Speter Check for bogus characters in the 0200-0237 range; since these are 690538032Speter used internally, very strange errors can occur if those 690638032Speter characters appear in headers. Problem noted by Anders Gertz 690738032Speter of Lysator. 690838032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 690938032Speter recipient mailer has the F=9 flag set, and only works on 691038032Speter text/plain body types. Code contributed by Marius Olafsson 691138032Speter of the University of Iceland. 691238032Speter Special case "postmaster" name so that it is always treated as lower 691338032Speter case in alias files regardless of configuration settings; 691438032Speter this prevents some potential problems where "Postmaster" or 691538032Speter "POSTMASTER" might not match "postmaster". In most cases 691638032Speter this change is a no-op. 691738032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 691838032Speter Costales. 691938032Speter The -a map flag was ignored for dequote maps. Problem noted by 692038032Speter Bryan Costales. 692138032Speter Fix core dump when a lookup of a class "prog" map returns no 692238032Speter response. Patch from Bryan Costales. 692338032Speter Log instances where sendmail is deferring or rejecting connections 692438032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 692538032Speter Include port number in process title for network daemons. Suggested 692638032Speter by Kyle Jones of UUNET. 692738032Speter Send ``double bounces'' (errors that occur when sending an error 692838032Speter message) to the address indicated in the DoubleBounceAddress 692938032Speter option (default: postmaster). Previously they were always 693038032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 693138032Speter Add new mode, -bD, that acts like -bd in all respects except that 693238032Speter it runs in foreground. This is useful for using with a 693338032Speter wrapper that "watches" system services. Suggested by Kyle 693438032Speter Jones of UUNET. 693538032Speter Fix botch in spacing around (parenthesized) comments in addresses 693638032Speter when the comment comes before the address. Patch from 693738032Speter Motonori Nakamura of Kyoto University. 693838032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 693938032Speter that are being bounced to postmaster, rather than "Returned 694038032Speter mail". This permits the person who is postmaster more 694138032Speter easily determine what messages are to their role as 694238032Speter postmaster versus bounces to mail they actually sent. Based 694338032Speter on a suggestion by Motonori Nakamura. 694438032Speter Add new value "time" for QueueSortOrder option; this causes the queue 694538032Speter to be sorted strictly by the time of submission. Note that 694643730Speter this can cause very bad behavior over slow lines (because 694738032Speter large jobs will tend to delay small jobs) and on nodes with 694838032Speter heavy traffic (because old things in the queue for hosts that 694938032Speter are down delay processing of new jobs). Also, this does not 695038032Speter guarantee that jobs will be delivered in submission order 695138032Speter unless you also set DeliveryMode=queue. In general, it should 695238032Speter probably only be used on the command line, and only in 695338032Speter conjunction with -qRhost.domain. In fact, there are very few 695438032Speter cases where it should be used at all. Based on an 695538032Speter implementation by Motonori Nakamura. 695638032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 695738032Speter the same manner as other rulesets. Previously a temporary 695838032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 695938032Speter of Stanford University. 696038032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 696138032Speter 5yz (permanent failure) code. The next MX host will still be 696238032Speter tried if the connection cannot be opened in the first place 696338032Speter or if the MAIL command returns a 4yz (temporary failure) code. 696438032Speter (It's hard to know what to do here, since neither RFC 974 nor 696538032Speter RFC 1123 specify when to proceed to the next MX host.) 696638032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 696738032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 696838032Speter This causes map lookups that get a temporary failure (e.g., 696938032Speter name server failure) to _not_ defer the delivery of the 697038032Speter message. This should only be used if your configuration file 697138032Speter is prepared to do something sensible in this case. Based on 697238032Speter an idea by Gregory Shapiro of WPI. 697338032Speter Fix problem finding network interface addresses. Patch from 697438032Speter Motonori Nakamura. 697538032Speter Don't reject qf entries that are not owned by your effective uid if 697690792Sgshapiro you are not running set-user-ID; this makes management of 697780785Sgshapiro certain kinds of firewall setups difficult. Patch 697880785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 697938032Speter Add persistent host status. This keeps the information normally 698038032Speter maintained within a single queue run in disk files that are 698138032Speter shared between sendmail instances. The HostStatusDirectory 698238032Speter is the directory in which the information is maintained. If 698338032Speter not set, persistent host status is turned off. If not a full 698438032Speter pathname, it is relative to the queue directory. A common 698538032Speter value is ".hoststat". 698638032Speter There are also two new operation modes: 698738032Speter * -bh prints the status of hosts that have had recent 698838032Speter connections. 698938032Speter * -bH purges the host statuses. No attempt is made to save 699038032Speter recent status information. 699138032Speter This feature was originally written by Paul Vixie of Vixie 699238032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 699338032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 699438032Speter with my insistence that things fit cleanly into the V8 699538032Speter framework is gratefully appreciated. 699638032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 699738032Speter operate). Avoids letting two sendmails on the local machine 699864562Sgshapiro open connections to the same remote host at the same time. 699938032Speter This reduces load on the other machine, but can cause mail to 700038032Speter be delayed (for example, if one sendmail is delivering a huge 700138032Speter message, other sendmails won't be able to send even small 700238032Speter messages). Also, it requires another file descriptor (for the 700338032Speter lock file) per connection, so you may have to reduce 700438032Speter ConnectionCacheSize to avoid running out of per-process 700538032Speter file descriptors. Based on the persistent host status code 700638032Speter contributed by Paul Vixie and Mark Lovell. 700738032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 700838032Speter SafeFileEnvironment option is set. Problem noted by Bryan 700938032Speter Costales. 701038032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 701138032Speter file. Problem noted by Bryan Costales. 701238032Speter If a job was aborted using the interrupt signal (e.g., control-C from 701338032Speter the keyboard), on some occasions an empty df file would be 701438032Speter left around; these would collect in the queue directory. 701538032Speter Problem noted by Bryan Costales. 701638032Speter Change the makesendmail script to enhance the search for Makefiles 701738032Speter based on release number. For example, on SunOS 5.5.1, it will 701838032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 701938032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 702038032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 702138032Speter Webmasters. 702238032Speter When creating maps using "newaliases", always map the keys to lower 702338032Speter case when creating the map unless the -f flag is specified on 702438032Speter the map itself. Previously this was done based on the F=u 702538032Speter flag in the local mailer, which meant you could create aliases 702638032Speter that you could never access. Problem noted by Bob Wu of DEC. 702738032Speter When a job was read from the queue, the bits causing notification on 702838032Speter failure or delay were always set. This caused those 702938032Speter notifications to be sent even if NOTIFY=NEVER had been 703038032Speter specified. Problem noted by Steve Hubert of the University 703138032Speter of Washington, Seattle. 703238032Speter Add new configurable routine validate_connection (in conf.c). This 703338032Speter lets you decide if you are willing to accept traffic from 703438032Speter this host. If it returns FALSE, all SMTP commands will return 703538032Speter "550 Access denied". -DTCPWRAPPERS will include support for 703638032Speter TCP wrappers; you will need to add -lwrap to the link line. 703738032Speter (See src/READ_ME for details.) 703838032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 703938032Speter bounces. Some people seemed to think that this could be 704038032Speter confusing (even though it is true). Suggested by Motonori 704138032Speter Nakamura. 704238032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 704338032Speter user early in processing to avoid potential security problems. 704438032Speter However, this means that all .forward and :include: files must 704538032Speter be readable by that user, and all files to be written must be 704638032Speter writable by that user and all programs will be executed by that 704738032Speter user. It is also incompatible with the SafeFileEnvironment 704838032Speter option. In other words, it may not actually add much to 704938032Speter security. However, it should be useful on firewalls and other 705038032Speter places where users don't have accounts and the aliases file is 705138032Speter well constrained. 705238032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 705338032Speter only on the first attempt to delivery to an address. It could 705438032Speter be set to be lower than Timeout.connect on the principle that 705538032Speter the mail should go through quickly to responsive hosts; less 705638032Speter responsive hosts get to wait for the next queue run. 705738032Speter Fix a problem on Solaris that occasionally causes programs 705838032Speter (such as vacation) to hang with their standard input connected 705938032Speter to a UDP port. It also created some signal handling problems. 706038032Speter The problems turned out to be an interaction between vfork(2) 706138032Speter and some of the libraries, particularly NIS/NIS+. I am 706238032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 706338032Speter Change user class map to do the same matching that actual delivery 706438032Speter will do instead of just a /etc/passwd lookup. This adds 706538032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 706638032Speter The Timeout.* options are not safe -- they can be used to create a 706738032Speter denial-of-service attack. Problem noted by Christophe 706838032Speter Wolfhugel. 706943730Speter Don't send PostmasterCopy messages in the event of a "delayed" 707038032Speter notification. Suggested by Barry Bouwsma. 707138032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 707238032Speter option is set, since this disables VERB mode. Suggested 707338032Speter by John Hawkinson of MIT. 707438032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 707538032Speter by Motonori Nakamura of Kyoto University. 707638032Speter Only queue messages on transient .forward open failures if there 707743730Speter were no successful opens. The previous behavior caused it 707838032Speter to queue even if a "fall back" .forward was found. Problem 707938032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 708038032Speter and Computer Science (DISCS), NUS, Singapore. 708138032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 708238032Speter is bouncing because of a MIME error during 8->7 bit conversion; 708338032Speter the encapsulated message will bounce again, causing a loop. 708438032Speter Problem noted by Steve Hubert of the University of Washington. 708538032Speter Create xf (transcript) files using the TempFileMode option value 708638032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 708738032Speter National University of Singapore. 708838032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 708938032Speter detect cases where DefaultUid is set to something that the 709038032Speter system can't cope with. 709138032Speter PORTABILITY FIXES: 709238032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 709338032Speter Atlas International. 709438032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 709538032Speter <bicknell@ufp.org>. 709638032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 709738032Speter work on the first recipient of a message due to a 709838032Speter bug in the getpwent family.

Contributed by 714338032Speter Robert La Ferla of Hot Software. 714438032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 714538032Speter (where "code" is an exit status) on domains (previously 714638032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 714738032Speter Foundation. 714838032Speter CONFIG: hooks for IPv6-style domain literals. 714938032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 715038032Speter if it is undefined the AliasFile option is never set; this 715138032Speter should be transparent for most everyone. Suggested by John 715238032Speter Myers of CMU. 715338032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 715438032Speter domain listed in $=w is masqueraded. With it, only those 715538032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 715638032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 715738032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 715838032Speter hosts under those domains as well as the domain headers 715938032Speter themselves. For example, if a configuration had 716038032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 716138032Speter foo.com would be masqueraded; with it, *.foo.com would be 716238032Speter masqueraded as well. Based on an implementation by Richard 716338032Speter (Pug) Bainter of U. Texas. 716438032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 716538032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 716638032Speter Keys are user names; values are outgoing mail addresses. Yes, 716738032Speter this does overlap with the user database, and figuring out 716838032Speter just when to use which one may be tricky. Based on code 716938032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 717038032Speter from Per Hedeland of Ericsson. 717138032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 717238032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 717338032Speter Keys are either fully qualified addresses or just the host 717438032Speter part (with the @ sign). For example, a table containing: 717538032Speter info@foo.com foo-info 717638032Speter info@bar.com bar-info 717738032Speter @baz.org jane@elsewhere.net 717838032Speter would send all mail destined for info@foo.com to foo-info 717938032Speter (which is presumably an alias), mail addressed to info@bar.com 718038032Speter to bar-info, and anything addressed to anyone at baz.org will 718138032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 718238032Speter and baz.org must all be in $=w. Based on discussions with 718338032Speter a great many people. 718438032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 718538032Speter Suggested by Richard Bainter. 718638032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 718738032Speter "fax" mailer. 718838032Speter CONFIG: allow mailertable entries to resolve to local:user; this 718938032Speter passes the original user@host in to procmail-style local 719038032Speter mailers as the "detail" information to allow them to do 719138032Speter additional clever processing. From Joe Pruett of 719238032Speter Teleport Corporation. Delivery to the original user can 719338032Speter be done by specifying "local:" (with nothing after the colon). 719438032Speter CONFIG: allow any context that takes "mailer:domain" to also take 719538032Speter "mailer:user@domain" to force mailing to the given user; 719638032Speter "local:user" can also be used to do local delivery. This 719738032Speter applies on *_RELAY and in the mailertable entries. Based 719838032Speter on a suggestion by Ribert Kiessling of Easynet. 719938032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 720038032Speter limits the possible domains; this reduces the number of DNS 720138032Speter lookups required to support this feature. For example, 720238032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 720338032Speter to domains under my.site.com. Code contributed by Anthony 720438032Speter Thyssen <anthony@cit.gu.edu.au>. 720538032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 720638032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 720738032Speter of WPI. 720838032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 720938032Speter event you have to define local mailers. Suggested by 721038032Speter Gregory Shapiro of WPI. 721138032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 721238032Speter be misinterpreted as a list:...; syntax. Based on a patch by 721338032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 721438032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 721538032Speter remotely connected. The address host!user was being 721638032Speter converted to host!user@thishost instead of host!user@uurelay. 721738032Speter Problem noted by William Gianopoulos of Raytheon Company. 721838032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 721938032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 722038032Speter "User has moved"; the former wording was confusing if the 722138032Speter new address is still on the local host. Based on a suggestion 722238032Speter by Andreas Luik. 722338032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 722438032Speter However, the class is not pre-initialized to contain root. 722538032Speter Suggested by Gregory Neil Shapiro. 722638032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 722738032Speter Wolfhugel. 722838032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 722938032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 723038032Speter well: this produces a slightly different mailbox format (no 723138032Speter Content-Length: headers), file ownerships and modes are 723238032Speter different (not owned by group mail; mode 600 instead of 660), 723338032Speter and the local mailer flags will have to be tweaked (make them 723438032Speter match bsd4.4) in order to use this mailer. Patches from Paul 723538032Speter Hammann of the Missouri Research and Education Network. 723638032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 723738032Speter was a delivery error, such as if the ownership on the file 723838032Speter was wrong or the mode changed between the initial stat and 723938032Speter the open. Problem reported by William Colburn of the New 724038032Speter Mexico Institute of Mining and Technology. 724138032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 724238032Speter Costales. 724338032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 724438032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 724538032Speter honored. Fix from Michael Scott Shappe. 724638032Speter PRALIASES: add man page contributed by Keith Bostic of BSDI. 724738032Speter NEW FILES: 724838032Speter src/Makefiles/Makefile.AIX.2 724938032Speter src/Makefiles/Makefile.IRIX.6.2 725038032Speter src/Makefiles/Makefile.maxion 725138032Speter src/Makefiles/Makefile.NCR.MP-RAS.3.x 725238032Speter src/Makefiles/Makefile.SCO.5.x 725338032Speter src/Makefiles/Makefile.UXPDSV20 725438032Speter mailstats/mailstats.8 725538032Speter praliases/praliases.8 725638032Speter cf/cf/generic-nextstep3.3.mc 725738032Speter cf/feature/genericstable.m4 725838032Speter cf/feature/limited_masquerade.m4 725938032Speter cf/feature/masquerade_entire_domain.m4 726038032Speter cf/feature/virtusertable.m4 726138032Speter cf/ostype/aix2.m4 726238032Speter cf/ostype/altos.m4 726338032Speter cf/ostype/maxion.m4 726438032Speter cf/ostype/solaris2.ml.m4 726538032Speter cf/ostype/uxpds.m4 726638032Speter contrib/re-mqueue.pl 726738032Speter DELETED FILES: 726838032Speter src/Makefiles/Makefile.Solaris 726938032Speter contrib/xla/README 727038032Speter contrib/xla/xla.c 727138032Speter RENAMED FILES: 727238032Speter src/Makefiles/Makefile.NCR3000 => Makefile.NCR.MP-RAS.2.x 727338032Speter src/Makefiles/Makefile.SCO.3.2v4.2 => Makefile.SCO.4.2 727438032Speter src/Makefiles/Makefile.UXPDS => Makefile.UXPDSV10 727538032Speter src/Makefiles/Makefile.NeXT => Makefile.NeXT.2.x 727638032Speter src/Makefiles/Makefile.NEXTSTEP => Makefile.NeXT.3.x 727738032Speter 727864562Sgshapiro8.7.6/8.7.3 1996/09/17 727938032Speter SECURITY: It is possible to force getpwuid to fail when writing the 728038032Speter queue file, causing sendmail to fall back to running programs 728138032Speter as the default user. This is not exploitable from off-site. 728238032Speter Workarounds include using a unique user for the DefaultUser 728338032Speter (old u & g options) and using smrsh as the local shell. 728438032Speter SECURITY: fix some buffer overruns; in at least one case this allows 728538032Speter a local user to get root. This is not known to be exploitable 728638032Speter from off-site. The workaround is to disable chfn(1) commands. 728738032Speter 728864562Sgshapiro8.7.5/8.7.3 1996/03/04 728938032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 729038032Speter in some case cause connections to hang or messages to have 729138032Speter extra spaces in odd places. Patch from Eric Wassenaar; 729238032Speter reports from Eric Hall of Chiron Corporation, Stephen 729338032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 729438032Speter and others. 729538032Speter 729664562Sgshapiro8.7.4/8.7.3 1996/02/18 729738032Speter SECURITY: In some cases it was still possible for an attacker to 729838032Speter insert newlines into a queue file, thus allowing access to 729938032Speter any user (except root). 730038032Speter CONFIG: no changes -- it is not a bug that the configuration 730138032Speter version number is unchanged. 730238032Speter 730364562Sgshapiro8.7.3/8.7.3 1995/12/03 730438032Speter Fix botch in name server timeout in RCPT code; this problem caused 730538032Speter two responses in SMTP, which breaks things horribly. Fix 730638032Speter from Gregory Neil Shapiro of WPI. 730738032Speter Verify that L= value on M lines cannot be negative, which could cause 730838032Speter negative array subscripting. Not a security problem since 730938032Speter this has to be in the config file, but it could have caused 731038032Speter core dumps. Pointed out by Bryan Costales. 731138032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 731238032Speter Costales. 731338032Speter PORTABILITY FIXES: 731438032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 731538032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 731638032Speter order. Tweak it to work properly. Based on fixes 731738032Speter from Fletcher Mattox of UTexas and Betty Lee of 731838032Speter Stanford University. 731938032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 732038032Speter Deficiency pointed out by Bryan Costales of ICSI. 732138032Speter 732264562Sgshapiro8.7.2/8.7.2 1995/11/19 732338032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 732438032Speter OperatorChars, and UnixFromLine options. They were not 732538032Speter properly repaired in 8.7.1. 732638032Speter Completely delete the Bcc: header if and only if there are other 732738032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 732838032Speter last being a historic botch, of course). If Bcc: is the 732938032Speter only recipient header in the message, its value is tossed, 733043730Speter but the header name is kept. The old behavior (always keep 733138032Speter the header name and toss the value) allowed primary recipients 733238032Speter to see that a Bcc: went to _someone_. 733338032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 733438032Speter sender to <address> using -f'' syslog messages. Suggested 733538032Speter by Kari Hurtta. 733638032Speter If a sequence or switch map lookup entry gets a tempfail but then 733738032Speter continues on to another map type, but the name is not found, 733838032Speter return a temporary failure from the sequence or switch map. 733938032Speter For example, if hosts search ``dns files'' and DNS fails 734038032Speter with a tempfail, the hosts map will go on and search files, 734138032Speter but if it fails the whole thing should be a tempfail, not 734238032Speter a permanent (host unknown) failure, even though that is the 734338032Speter failure in the hosts.files map. This error caused hard 734438032Speter bounces when it should have requeued. 734538032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 734690792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 734738032Speter working properly due to excessive paranoia. Pointed out by 734838032Speter John Hawkinson of Panix. 734938032Speter An SMTP RCPT command referencing a host that gave a nameserver 735038032Speter timeout would return a 451 command (8.6 accepted it and 735143730Speter queued it locally). Revert to the 8.6 behavior in order 735238032Speter to simplify queue management for clustered systems. Suggested 735338032Speter by Gregory Neil Shapiro of WPI. The same problem could break 735438032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 735538032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 735638032Speter Infobiogen. 735738032Speter Fix possible buffer overflow in munchstring(). This was not a security 735838032Speter problem because you couldn't specify any argument to this 735938032Speter without first giving up root privileges, but it is still a 736038032Speter good idea to avoid future problems. Problem noted by John 736138032Speter Hawkinson and Sam Hartman of MIT. 736238032Speter ``452 Out of disk space for temp file'' messages weren't being 736338032Speter printed. Fix from David Perlin of Nanosoft. 736443730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 736538032Speter is not set, since this is required to get the actual DSNs 736638032Speter created. Problem pointed out by John Gardiner Myers of CMU. 736738032Speter Log permission problems that cause .forward and :include: files to 736838032Speter be untrusted or ignored on log level 12 and higher. Suggested 736938032Speter by Randy Martin of Clemson University. 737038032Speter Allow user ids in U= clauses of M lines to have hyphens and 737138032Speter underscores. 737238032Speter Fix overcounting of recipients -- only happened when sending to an 737338032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 737438032Speter of Systems and Computer Technology Corporation. 737538032Speter If a message is sent to an address that fails, the error message that 737638032Speter is returned could show some extraneous "success" information 737738032Speter included even if the user did not request success notification, 737838032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 737938032Speter Config files that had no AliasFile definition were defaulting to 738038032Speter using /etc/aliases; this caused problems with nullclient 738138032Speter configurations. Change it back to the 8.6 semantics of 738238032Speter having no local alias file unless it is declared. Problem 738338032Speter noted by Charles Karney of Princeton University. 738438032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 738538032Speter Costales of ICSI. 738638032Speter Map lookups of class "userdb" maps were always case sensitive; they 738738032Speter should be controlled by the -f flag like other maps. Pointed 738838032Speter out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. 738938032Speter Fix problem that caused some addresses to be passed through ruleset 5 739038032Speter even when they were tagged as "sticky" by prefixing the 739138032Speter address with an "@". Patch from Thomas Dwyer III of Michigan 739238032Speter Technological University. 739338032Speter When converting a message to Quoted-Printable, prevent any lines with 739438032Speter dots alone on a line by themselves. This is because of the 739538032Speter preponderance of broken mailers that still get this wrong. 739638032Speter Code contributed by Per Hedeland of Ericsson. 739738032Speter Fix F{macro}/file construct -- it previously did nothing. Pointed 739838032Speter out by Bjart Kvarme of USIT/UiO (Norway). 739938032Speter Announce whether a cached connection is SMTP or ESMTP (in -v mode). 740038032Speter Requested by Allan Johannesen. 740138032Speter Delete check for text format of alias files -- it should be legal 740238032Speter to have the database format of the alias files without the 740338032Speter text version. Problem pointed out by Joe Rhett of Navigist, 740438032Speter Inc. 740538032Speter If "Ot" was specified with no value, the TZ variable was not properly 740638032Speter imported from the environment. Pointed out by Frank Crawford 740738032Speter <frank@ansto.gov.au>. 740838032Speter Some architectures core dumped on "program" maps that didn't have 740938032Speter extra arguments. Patch from Booker C. Bense of Stanford 741038032Speter University. 741138032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 741238032Speter the parent should do this. Fix from Brian Coan of the 741338032Speter Association for Progressive Communications. 741438032Speter If MinQueueAge was set and a message was considered but not run 741538032Speter during a queue run and the Timeout.queuereturn interval was 741638032Speter reached, a "timed out" error message would be returned that 741738032Speter didn't include the failed address (and claimed to be a warning 741838032Speter even though it was fatal). The fix is to not return such 741938032Speter messages until they are actually tried, i.e., in the next 742038032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 742138032Speter SINTEF RUNIT, Oslo. 742238032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 742338032Speter that have the hes_getmailhost() routine.

Bug 747038032Speter pointed out by John Hawkinson of MIT. 747138032Speter Fix strange case of an executable called by a program map that 747238032Speter returns a value but also a non-zero exit status; this 747338032Speter would give contradictory results in the higher level; in 747438032Speter particular, the default clause in the map lookup would be 747538032Speter ignored. Change to ignore the value if the program returns 747638032Speter non-zero exit status. From Tom Moore of AT&T GIS. 747738032Speter Shorten parameters passed to syslog() in some contexts to avoid a 747838032Speter bug in many vendors' implementations of that routine. Although 747938032Speter this isn't really a bug in sendmail per se, and my solution 748038032Speter has to assume that syslog() has at least a 1K buffer size 748138032Speter internally (I know some vendors have shortened this 748238032Speter dramatically -- they're on their own), sendmail is a popular 748338032Speter target. Also, limit the size of %s arguments in sprintf. 748438032Speter These both have possible security implications. Solutions 748538032Speter suggested by Casper Dik of Sun's Network Security Group 748638032Speter (Holland), Mark Seiden, and others. 748738032Speter Fix a problem that might cause a non-standard -B (body type) 748838032Speter parameter to be passed to the next server with undefined 748938032Speter results. This could have security implications. 749038032Speter If a filesystem was at > 100% utilization, the freediskspace() 749138032Speter routine incorrectly returned an error rather than zero. 749238032Speter Problem noted by G. Paul Ziemba of Alantec. 749338032Speter Change MX sort order so that local hostnames (those in $=w) always 749438032Speter sort first within a given preference. This forces the bestmx 749538032Speter map to always return the local host first, if it is included 749638032Speter in the list of highest priority MX records. From K. Robert 749738032Speter Elz. 749838032Speter Avoid some possible null pointer dereferences. Fixes from Randy 749938032Speter Martin <WOLF@CLEMSON.EDU> 750038032Speter When sendmail starts up on systems that have no fully qualified 750138032Speter domain name (FQDN) anywhere in the first matching host map 750238032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 750338032Speter sendmail would sleep to try to find a FQDN, which it really 750438032Speter really needs. This has been changed to fall through to the 750538032Speter next map type if it can't find a FQDN -- i.e., if the hosts 750638032Speter file doesn't have a FQDN, it will try dns even though the 750738032Speter short name was found in /etc/hosts. This is probably a crock, 750838032Speter but many people have hosts files without FQDNs. Remember: 750938032Speter domain names are your friends. 751038032Speter Log a high-priority message if you can't find your FQDN during startup. 751138032Speter Suggested by Simon Barnes of Schlumberger Limited. 751238032Speter When using Hesiod, initialize it early to improve error reporting. 751338032Speter Patch from Don Lewis of Silicon Systems, Inc. 751438032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 751538032Speter connection timeout in the kernel. Add a new "connect" timeout 751638032Speter to limit this time. Defaults to zero (use whatever the 751738032Speter kernel provides). Based on code contributed by J.R. Oldroyd 751838032Speter of TerraNet. 751938032Speter Under some circumstances, a failed message would not be properly 752038032Speter removed from the queue, causing tons of bogus error messages. 752138032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 752238032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 752338032Speter of WPI. 752438032Speter PORTABILITY FIXES: 752538032Speter On IRIX 5.x, there was an inconsistency in the setting 752638032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 754238032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 754338032Speter otherwise the F=S causes the From_ line to imply that root is 754438032Speter the sender. Problem pointed out by Claude Scarpelli of 754538032Speter Infobiogen (France). 754638032Speter NEW FILES: 754738032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 754838032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 754938032Speter src/Makefiles/Makefile.UXPDS 755038032Speter 755164562Sgshapiro8.7/8.7 1995/09/16 755238032Speter Fix a problem that could cause sendmail to run out of file 755338032Speter descriptors due to a trashed data structure after a 755438032Speter vfork.

This was used "safely" in the sense 756038032Speter that it only did a stat, but it would have set the 756138032Speter map modification time improperly. Problem pointed out 756238032Speter by Roy Mongiovi of Georgia Tech. 756338032Speter Clean up the Subject: line on warning messages and return 756438032Speter receipts so that they don't say "Returned mail:"; this 756538032Speter can be confusing. 756638032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 756738032Speter useful enough to make it worthwhile printing on "-d". 756838032Speter Avoid logging alias statistics every time you read the alias 756938032Speter file on systems with no database method compiled in. 757038032Speter If you have a name with a trailing dot, and you try looking it 757138032Speter up using gethostbyname without the dot (for /etc/hosts 757238032Speter compatibility), be sure to turn off RES_DEFNAMES and 757338032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 757438032Speter Problem noted by Charles Amos of the University of 757538032Speter Maryland. 757638032Speter Don't do timeouts in collect if you are not running SMTP. 757738032Speter There is nothing that says you can't have a long 757838032Speter running program piped into sendmail (possibly via 757938032Speter /bin/mail, which just execs sendmail). Problem reported 758038032Speter by Don "Truck" Lewis of Silicon Systems. 758138032Speter Try gethostbyname() even if the DNS lookup fails iff option I 758238032Speter is not set. This allows you to have hosts listed in 758338032Speter NIS or /etc/hosts that are not known to DNS. It's normally 758438032Speter a bad idea, but can be useful on firewall machines. This 758538032Speter should really be broken out on a separate flag, I suppose. 758638032Speter Avoid compile warnings against BIND 4.9.3, which uses function 758738032Speter prototypes.

From Kyle Jones of UUNET. 759238032Speter SECURITY: avoid denial-of-service attacks possible by destroying 759338032Speter the alias database file by setting resource limits low. 759438032Speter This involves adding two new compile-time options: 759538032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 759638032Speter available) and HASULIMIT (indicating that ulimit(2) support 759738032Speter is available -- the Release 3 form is used). The former 759838032Speter is assumed on BSD-based systems, the latter on System 759938032Speter V-based systems. Attack noted by Phil Brandenberger of 760038032Speter Swarthmore University. 760138032Speter New syntaxes in test (-bt) mode: 760238032Speter ``.Dmvalue'' will define macro "m" to "value". 760338032Speter ``.Ccvalue'' will add "value" to class "c". 760438032Speter ``=Sruleset'' will dump the contents of the indicated 760538032Speter ruleset. 760638032Speter ``=M'' will display the known mailers. 760738032Speter ``-ddebug-spec'' is equivalent to the command-line 760838032Speter -d debug flag. 760938032Speter ``$m'' will print the value of macro $m. 761038032Speter ``$=c'' will print the contents of class $=c. 761138032Speter ``/mx host'' returns the MX records for ``host''. 761238032Speter ``/parse address'' will parse address, returning the value of 761338032Speter crackaddr (essentially, the comment information) 761438032Speter and the parsed address. 761538032Speter ``/try mailer address'' will rewrite address into the form 761638032Speter it will have when presented to the indicated mailer. 761738032Speter ``/tryflags flags'' will set flags used by parsing. The 761838032Speter flags can be `H' for header or `E' for envelope, 761938032Speter and `S' for sender or `R' for recipient. These 762038032Speter can be combined, so `HR' sets flags for header 762138032Speter recipients. 762238032Speter ``/canon hostname'' will try to canonify hostname and 762338032Speter return the result. 762438032Speter ``/map mapname key'' will look up `key' in the indicated 762538032Speter `mapname' and return the result. 762638032Speter Somewhat better handling of UNIX-domain socket addresses -- it 762738032Speter should show the pathname rather than hex bytes. 762838032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 762938032Speter the header for envelope sender information and uses 763038032Speter CR-LF as message terminators. It was thought to be 763138032Speter obsolete (used only for Arpanet NCP protocols), but it 763238032Speter turns out that the UK ``Grey Book'' protocols require 763338032Speter that functionality. 763438032Speter Fix a fix in previous release -- if gethostname and gethostbyname 763538032Speter return a name without dots, and if an attempt to canonify 763638032Speter that name fails, wait one minute and try again. This can 763738032Speter result in an extra 60 second delay on startup if your system 763838032Speter hostname (as returned by hostname(1)) has no dot and no names 763938032Speter listed in /etc/hosts or your NIS map have a dot. 764038032Speter Check for proper domain name on HELO and EHLO commands per 764138032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 764238032Speter of Michigan Technological University. 764338032Speter Relax chownsafe rules slightly -- old version said that if you 764438032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 764538032Speter if fpathconf returned EINVAL or ENOSYS), assume that 764638032Speter chown is not safe. The new version falls back to whether 764738032Speter you are on a BSD system or not. This is important for 764838032Speter SunOS, which apparently always returns one of those 764938032Speter error codes. This impacts whether you can mail to files 765038032Speter or not. 765138032Speter Syntax errors such as unbalanced parentheses in the configuration 765238032Speter file could be omitted if you had "Oem" prior to the 765338032Speter syntax error in the config file. Change to always print 765438032Speter the error message. It was especially weird because it 765538032Speter would cause a "warning" message to be sent to the Postmaster 765638032Speter for every message sent (but with no transcript). Problem 765738032Speter noted by Gregory Paris of Motorola. 765838032Speter Rewrite collect and putbody to handle full 8-bit data, including 765938032Speter zero bytes.

This is to handle the 772838032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 772938032Speter assume that ``group name:'' is a comment on the first 773038032Speter address and the ``;'' is a comment on the last address). 773138032Speter This requires config file support to get right. It does 773238032Speter understand that :: is NOT this syntax, and can be turned 773338032Speter off completely by setting the ColonOkInAddresses option. 773438032Speter Level 6 config files added with new mailer flags: 773538032Speter A Addresses are aliasable. 773638032Speter i Do udb rewriting on envelope as well as header 773738032Speter sender lines. Applies to the from address mailer 773838032Speter flags rather than the recipient mailer flags. 773938032Speter j Do udb rewriting on header recipient addresses. 774038032Speter Applies to the sender mailer flags rather than the 774138032Speter recipient mailer flags. 774238032Speter k Disable check for loops when doing HELO command. 774338032Speter o Always run as the mail recipient, even on local 774438032Speter delivery. 774538032Speter w Check for an /etc/passwd entry for this user. 774638032Speter 5 Pass addresses through ruleset 5. 774738032Speter : Check for :include: on this address. 774838032Speter | Check for |program on this address. 774938032Speter / Check for /file on this address. 775038032Speter @ Look up sender header addresses in the user 775138032Speter database. Applies to the mailer flags for the 775238032Speter mailer corresponding to the envelope sender 775338032Speter address, rather than to recipient mailer flags. 775438032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 775538032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 775638032Speter mailers, and the ColonOkInAddresses option. 775738032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 775838032Speter John Beck of Hewlett-Packard, who generously contributed 775938032Speter their implementation to me, which I then didn't use (see 776038032Speter mime.c for an explanation of why). This adds the 776138032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 776238032Speter to control handling of 8-bit data. These have to cope with 776338032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 776438032Speter 8-bit data that is entered without declaring it as 8-bit 776538032Speter MIME -- technically this is illegal according to the 776638032Speter specs) and labelled 8-bit data (that is, it was declared 776738032Speter as 8BITMIME in the ESMTP session or by using the 776838032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 776938032Speter set then 8-bit data is sent to non-8BITMIME machines 777038032Speter instead of converting to 7 bit (essentially using 777138032Speter just-send-8 semantics). The values for EightBitMode are: 777238032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 777338032Speter any necessary conversion of 8BITMIME to 7BIT 777438032Speter (essentially, the full MIME option). 777538032Speter p pass unlabelled 8-bit input, but convert labelled 777638032Speter 8BITMIME input to 7BIT as required (default). 777738032Speter s strict adherence: reject unlabelled 8-bit input, 777838032Speter convert 8BITMIME to 7BIT as required. The F=8 777938032Speter flag is ignored. 778038032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 778138032Speter the setting of F=8. 778238032Speter Add new internal class 'n', which is the set of MIME Content-Types 778338032Speter which can not be 8 to 7 bit encoded because of other 778438032Speter considerations. Types "multipart/*" and "message/*" are 778538032Speter never directly encoded (although their components can be). 778638032Speter Add new internal class 's', which is the set of subtypes of the 778738032Speter MIME message/* content type that can be treated as though 778838032Speter they are an RFC822 message. It is predefined to have 778938032Speter "rfc822". Suggested By Kari Hurtta. 779038032Speter Add new internal class 'e'. This is the set of MIME 779138032Speter Content-Transfer-Encodings that can be converted to 779238032Speter a seven bit format (Quoted-Printable or Base64). It is 779338032Speter preinitialized to contain "7bit", "8bit", and "binary". 779438032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 779538032Speter short name) to set the default character set to use in the 779638032Speter Content-Type: header when doing encoding of an 8-bit message 779738032Speter which isn't marked as MIME into MIME format. If the C= 779838032Speter parameter is set on the Envelope From address, use that as 779938032Speter the default encoding; else use the DefaultCharSet option. 780038032Speter If neither is set, it defaults to "unknown-8bit" as 780138032Speter suggested by RFC 1428 section 3. 780238032Speter Allow ``U=user:group'' field in mailer definition to set a default 780338032Speter user and group that a mailer will be executed as. This 780438032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 780538032Speter also set, it is the uid/gid that will always be used (that 780638032Speter is, the controlling address is ignored). The values may be 780738032Speter numeric or symbolic; if only a symbolic user is given (no 780838032Speter group) that user's default group in the passwd file is used 780938032Speter as the group. Based on code donated by Chip Rosenthal of 781038032Speter Unicom. 781138032Speter Allow `u' option to also accept user:group as a value, in the same 781238032Speter fashion as the U= mailer option. 781338032Speter Add the symbolic time zone name in the Arpanet format dates (as 781438032Speter a comment). This adds a new compile-time configuration 781538032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 781638032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 781738032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 781838032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 781938032Speter timezone()), or TZ_NONE (don't include the comment). Code 782038032Speter from Chip Rosenthal. 782138032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 782238032Speter For example, 782338032Speter O Timeout.helo = 2m 782438032Speter There are also two new suboptions "queuereturn" and 782538032Speter "queuewarn"; these subsume the old T option. Thus, to 782638032Speter set them both the preferred new syntax is 782738032Speter O Timeout.queuereturn = 5d 782838032Speter O Timeout.queuewarn = 4h 782938032Speter Sort queue by host name instead of by message priority if the 783038032Speter QueueSortOrder option (no short name) is set is set to 783138032Speter ``host''. This makes better use of the connection cache, 783238032Speter but may delay more ``interactive'' messages behind large 783338032Speter backlogs under some circumstances. This is probably a 783438032Speter good option if you have high speed links or don't do lots 783538032Speter of ``batch'' messages, but less good if you are using 783638032Speter something like PPP on a 14.4 modem. Based on code 783738032Speter contributed by Roy Mongiovi of Georgia Tech (my main 783838032Speter contribution was to make it configurable). 783938032Speter Save i-number of df file in qf file to simplify rebuilding of queue 784038032Speter after disastrous disk crash. Suggested by Kyle Jones of 784138032Speter UUNET; closely based on code from KJS DECWRL code written 784238032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 784338032Speter are NOT back compatible with 8.6 -- that is, you can convert 784438032Speter from 8.6 to 8.7, but not the other direction. 784538032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 784638032Speter route-addrs in envelopes; this is because in some cases 784738032Speter they can be sent to the shell, which interprets them as 784838032Speter I/O redirection. 784938032Speter Don't include error file (option E) with return-receipts; this 785038032Speter can be confusing. 785138032Speter Don't send "Warning: cannot send" messages to owner-* or 785238032Speter *-request addresses. Suggested by Christophe Wolfhugel 785338032Speter of the Institut Pasteur, Paris. 785438032Speter Allow -O command line flag to set long form options. 785538032Speter Add "MinQueueAge" option to set the minimum time between attempts 785638032Speter to run the queue. For example, if the queue interval 785738032Speter (-q value) is five minutes, but the minimum queue age 785838032Speter is fifteen minutes, jobs won't be tried more often than 785938032Speter once every fifteen minutes. This can be used to give 786038032Speter you more responsiveness if your delivery mode is set to 786138032Speter queue-only. 786238032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 786338032Speter :include: and .forward files. 786438032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 786538032Speter key field name, the value field name, and the field 786638032Speter delimiter. The field delimiter can be a single character 786738032Speter or the sequence "\t" or "\n" for tab or newline. 786838032Speter These are for use by NIS+ and similar access methods. 786938032Speter Change maps to always strip quotes before lookups; the -q flag 787043730Speter turns off this behavior. Suggested by Motonori Nakamura. 787138032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 787238032Speter key and value field names respectively. Code donated by 787338032Speter Sun Microsystems. 787438032Speter Add "hesiod" map class. The "file name" is used as the 787538032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 787638032Speter first value found for the match. Code donated by Scott 787738032Speter Hutton of Indiana University. 787838032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 787938032Speter specify the name of the property that is searched as the 788038032Speter key and a -v flag to specify the name of the property that 788138032Speter is returned as the value (defaults to "members"). The 788238032Speter default map is "/aliases". Some code based on code 788338032Speter contributed by Robert La Ferla of Hot Software. 788438032Speter Add "text" map class. This does slow, linear searches through 788538032Speter text files. The -z flag specifies a column delimiter 788638032Speter (defaults to any sequence of white space), the -k flag 788738032Speter sets the key column number, and the -v flag sets the 788838032Speter value column number. Lines beginning with `#' are treated 788938032Speter as comments. 789038032Speter Add "program" map class to execute arbitrary programs. The search 789138032Speter key is presented as the last argument; the output is one 789238032Speter line read from the programs standard output. Exit statuses 789338032Speter are from sysexits.h. 789438032Speter Add "sequence" map class -- searches maps in sequence until it 789538032Speter finds a match. For example, the declarations: 789638032Speter Kmap1 ... 789738032Speter Kmap2 ... 789838032Speter Kmapseq sequence map1 map2 789938032Speter defines a map "mapseq" that first searches map1; if the 790038032Speter value is found it is returned immediately, otherwise 790138032Speter map2 is searched and the value returned. 790238032Speter Add "switch" map class. This is much like "sequence" except that 790338032Speter the ordering is fetched from an external file, usually 790438032Speter the system service switch. The parameter is the name of 790538032Speter the service to switch on, and the maps that it will use 790638032Speter are the name of the switch map followed by ".service_type". 790738032Speter For example, if the declaration of the map is 790838032Speter Ksample switch hosts 790938032Speter and the system service switch specifies that hosts are 791038032Speter looked up using dns and nis in that order, then this is 791138032Speter equivalent to 791238032Speter Ksample sequence sample.dns sample.nis 791338032Speter The subordinate maps (sample.*) must already be defined. 791438032Speter Add "user" map class -- looks up users using getpwnam. Takes a 791538032Speter "-v field" flag on the definition that tells what passwd 791638032Speter entry to return -- legal values are name, passwd, uid, gid, 791738032Speter gecos, dir, and shell. Generally expected to be used with 791838032Speter the -m (matchonly) flag. 791938032Speter Add "bestmx" map class -- returns the best MX value for the host 792038032Speter listed as the value. If there are several "best" MX records 792138032Speter for this host, one will be chosen at random. 792238032Speter Add "userdb" map class -- looks up entries in the user database. 792338032Speter The "file name" is actually the tag that will be used, 792438032Speter typically "mailname". If there are multiple entries 792538032Speter matching the name, the one chosen is undefined. 792638032Speter Add multiple queue timeouts (both return and warning). These are 792738032Speter set by the Precedence: or Priority: header fields to one of 792838032Speter three values. If a Priority: is set and has value "normal", 792964562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 793038032Speter used. If no priority is set, the Precedence: is consulted; 793138032Speter if negative, non-urgent timeouts are used; if greater than 793238032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 793338032Speter are used. The timeouts are set by setting the six timeouts 793438032Speter queue{warn,return}.{urgent,normal,non-urgent}. 793538032Speter Fix problem when a mail address is resolved to a $#error mailer 793638032Speter with a temporary failure indication; it works in SMTP, 793738032Speter but when delivering locally the mail is silently discarded. 793838032Speter This patch, from Kyle Jones of UUNET, bounces it instead 793938032Speter of queueing it (queueing is very hard). 794038032Speter When using /etc/hosts or NIS-style lookups, don't assume that 794138032Speter the first name in the list is the best one -- instead, 794238032Speter search for the first one with a dot. For example, if 794338032Speter an /etc/hosts entry reads 794438032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 794538032Speter this change will use the second name as the canonical 794638032Speter machine name instead of the initial, unqualified name. 794738032Speter Change dequote map to replace spaces in quoted text with a value 794838032Speter indicated by the -s flag on the dequote map definition. 794938032Speter For example, ``Mdequote dequote -s_'' will change 795038032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 795138032Speter quoted (because of the space character). Suggested by Dan 795238032Speter Oscarsson for use in X.400 addresses. 795338032Speter Implement long macro names as ${name}; long class names can 795438032Speter be similarly referenced as $={name} and $~{name}. 795538032Speter Definitions are (e.g.) ``D{name}value''. Names that have 795638032Speter a leading lower case letter or punctuation characters are 795738032Speter reserved for internal use by sendmail; i.e., config files 795838032Speter should use names that begin with a capital letter. Based 795938032Speter on code contributed by Dan Oscarsson. 796038032Speter Fix core dump if getgrgid returns a null group list (as opposed 796138032Speter to an empty group list, that is, a pointer to a list 796238032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 796338032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 796438032Speter failed, it called syserr which called newstr which called 796538032Speter xalloc.... The newstr is now avoided for "panic" messages. 796638032Speter Reported by Stuart Kemp of James Cook University. 796738032Speter Improve connection cache timeouts; previously, they were not even 796838032Speter checked if you were delivering to anything other than an 796938032Speter IPC-connected host, so a series of (say) local mail 797038032Speter deliveries could cause cached connections to be open 797138032Speter much longer than the specified timeout. 797238032Speter If an incoming message exceeds the maximum message size, stop 797338032Speter writing the incoming bytes to the queue data file, since 797438032Speter this can fill your mqueue partition -- this is a possible 797538032Speter denial-of-service attack. 797638032Speter Don't reject all numeric local user names unless HESIOD is 797738032Speter defined. It turns out that Posix allows all-numeric 797838032Speter user names. Fix from Tony Sanders of BSDI. 797938032Speter Add service switch support. If the local OS has a service 798038032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 798138032Speter on DEC systems) that will be used; otherwise, it falls back 798238032Speter to using a local mechanism based on the ServiceSwitchFile 798338032Speter option (default: /etc/service.switch). For example, if the 798438032Speter service switch lists "files" and "nis" for the aliases 798538032Speter service, that will be the default lookup order. the "files" 798638032Speter ("local" on DEC) service type expands to any alias files 798738032Speter you listed in the configuration file, even if they aren't 798838032Speter actually file lookups. 798938032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 799038032Speter variable which tells whether or not DNS should be considered 799138032Speter canonical. This is now determined based on whether or not 799238032Speter "dns" is in the service list for "hosts". 799338032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 799438032Speter Status Notifications). DSN notifications override 799538032Speter Return-Receipt-To: headers, which are bogus anyhow -- 799638032Speter support for them has been removed. 799738032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 799838032Speter definitions to define the types used in DSN returns for 799938032Speter MTA names, addresses, and diagnostics respectively. 800038032Speter Extend heuristic to force running in ESMTP mode to look for the 800138032Speter five-character string "ESMTP" anywhere in the 220 greeting 800238032Speter message (not just the second line). This is to provide 800338032Speter better compatibility with other ESMTP servers. 800438032Speter Print sequence number of job when running the queue so you can 800538032Speter easily see how much progress you have made. Suggested 800638032Speter by Peter Wemm of DIALix. 800738032Speter Map newlines to spaces in logged message-ids; some versions of 800838032Speter syslog truncate the rest of the line after newlines. 800938032Speter Suggested by Fletcher Mattox of U. Texas. 801038032Speter Move up forking for job runs so that if a message is split into 801138032Speter multiple envelopes you don't get "fork storms" -- this 801238032Speter also improves the connection cache utilization. 801338032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 801438032Speter the purposes of refusing to send error returns. Suggested 801538032Speter by Motonori Nakamura of Ritsumeikan University. 801638032Speter Relax rules on when a file can be written when referenced from 801738032Speter the aliases file: use the default uid/gid instead of the 801838032Speter real uid/gid. This allows you to create a file owned by 801938032Speter and writable only by the default uid/gid that will work 802090792Sgshapiro all the time (without having the set-user-ID bit set). Change 802138032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 802238032Speter Microsystems. 802338032Speter Add "DialDelay" option (no short name) to provide an "extra" 802438032Speter delay for dial on demand systems. If this is non-zero 802538032Speter and a connect fails, sendmail will wait this long and 802638032Speter then try again. If it takes longer than the kernel 802738032Speter timeout interval to establish the connection, this 802838032Speter option can give the network software time to establish 802938032Speter the link. The default units are seconds. 803038032Speter Move logging of sender information to be as early as possible; 803138032Speter previously, it could be delayed a while for SMTP mail 803238032Speter sent to aliases. Suggested by Brad Knowles of the 803338032Speter Defense Information Systems Agency. 803438032Speter Call res_init() before setting RES_DEBUG; this is required by 803538032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 803638032Speter the National Computer Security Center. 803738032Speter Add xdelay= field in logs -- this is a transaction delay, telling 803838032Speter you how long it took to deliver to this address on the 803938032Speter last try. It is intended to be used for sorting mailing 804038032Speter lists to favor "quick" addresses. Provided for use by 804138032Speter the mailprio scripts (see below). 804238032Speter If a map cannot be opened, and that map is non-optional, and 804338032Speter an address requires that map for resolution, queue the 804438032Speter map instead of bouncing it. This involves creating a 804538032Speter pseudo-class of maps called "bogus-map" -- if a required 804638032Speter map cannot be opened, the class is changed to bogus-map; 804738032Speter all queries against bogus-map return "tempfail". The 804838032Speter bogus-map class is not directly accessible. A sample 804938032Speter implementation was donated by Jem Taylor of Glasgow 805038032Speter University Computing Service. 805138032Speter Fix a possible core dump when mailing to a program that talks 805238032Speter SMTP on its standard input. Fix from Keith Moore of 805338032Speter the University of Kentucky. 805438032Speter Make it possible to resolve filenames to $#local $: @ /filename; 805538032Speter previously, the "@" would cause it to not be recognized 805638032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 805738032Speter Accept a -1 signal to re-exec the daemon. This only works if 805838032Speter argv[0] is a full path to sendmail. 805938032Speter Fix bug in "addr=..." field in O option on little-endian machines 806038032Speter -- the network number wasn't being converted to network 806138032Speter byte order. Patch from Kurt Lidl of Pix Technologies 806238032Speter Corporation. 806338032Speter Pre-initialize the resolver early on; this is to avoid a bug with 806438032Speter BIND 4.9.3 that can cause the _res.retry field to get 806538032Speter reset to zero, causing all name server lookups to time 806638032Speter out. Fix from Matt Day of Artisoft. 806738032Speter Restore T line (trusted users) in config file -- but instead of 806838032Speter locking out the -f flag, they just tell whether or not 806938032Speter an X-Authentication-Warning: will be added. This really 807038032Speter just creates new entries in class 't', so "Ft/file/name" 807138032Speter can be used to read trusted user names from a file. 807238032Speter Trusted users are also allowed to execute programs even 807338032Speter if they have a shell that isn't in /etc/shells. 807438032Speter Improve NEWDB alias file rebuilding so it will create them 807538032Speter properly if they do not already exist. This had been 807638032Speter a MAYBENEXTRELEASE feature in 8.6.9. 807738032Speter Check for @:@ entry in NIS maps before starting up to avoid 807838032Speter (but not prevent, sigh) race conditions. This ought to 807938032Speter be handled properly in ypserv, but isn't. Suggested by 808038032Speter Michael Beirne of Motorola. 808138032Speter Refuse connections if there isn't enough space on the filesystem 808238032Speter holding the queue. Contributed by Robert Dana of Wolf 808338032Speter Communications. 808438032Speter Skip checking for directory permissions in the path to a file 808538032Speter when checking for file permissions iff setreuid() 808638032Speter succeeded -- it is unnecessary in that case. This avoids 808738032Speter significant performance problems when looking for .forward 808838032Speter files. Based on a suggestion by Win Bent of USC. 808938032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 809038032Speter arbitrary ruleset number assigned or "Sname = integer" 809138032Speter to assign a specific ruleset number. Reference is 809238032Speter $>name_or_number. Names can be composed of alphas, digits, 809338032Speter underscore, or hyphen (first character must be non-numeric). 809438032Speter Allow -o flag on AliasFile lines to make the alias file optional. 809538032Speter From Bryan Costales of ICSI. 809638032Speter Add NoRecipientAction option to handle the case where there is 809738032Speter no legal recipient header in the message. It can take 809838032Speter on values: 809938032Speter None Leave the message as is. The 810038032Speter message will be passed on even 810138032Speter though it is in technically 810238032Speter illegal syntax. 810338032Speter Add-To Add a To: header with any 810438032Speter recipients that it can find from 810538032Speter the envelope. This risks exposing 810638032Speter Bcc: recipients. 810738032Speter Add-Apparently-To Add an Apparently-To: header. This 810838032Speter has almost no redeeming social value, 810938032Speter and is provided only for back 811038032Speter compatibility. 811138032Speter Add-To-Undisclosed Add a header reading 811238032Speter To: undisclosed-recipients:; 811338032Speter which will have the effect of 811438032Speter making the message legal without 811538032Speter exposing Bcc: recipients. 811638032Speter Add-Bcc To add an empty Bcc: header. 811738032Speter There is a chance that mailers down 811838032Speter the line will delete this header, 811938032Speter which could cause exposure of Bcc: 812038032Speter recipients. 812138032Speter The default is NoRecipientAction=None. 812238032Speter Truncate (rather than delete) Bcc: lines in the header. This 812338032Speter should prevent later sendmails (at least, those that don't 812438032Speter themselves delete Bcc:) from considering this message to 812538032Speter be non-conforming -- although it does imply that non-blind 812638032Speter recipients can see that a Bcc: was sent, albeit not to whom. 812738032Speter Add SafeFileEnvironment option. If declared, files named as delivery 812838032Speter targets must be regular files in addition to the regular 812938032Speter checks. Also, if the option is non-null then it is used as 813038032Speter the name of a directory that is used as a chroot(2) 813138032Speter environment for the delivery; the file names listed in an 813238032Speter alias or forward should include the name of this root. 813338032Speter For example, if you run with 813438032Speter O SafeFileEnvironment=/arch 813538032Speter then aliases should reference "/arch/rest/of/path". If a 813638032Speter value is given, sendmail also won't try to save to 813738032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 813838032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 813938032Speter Support -A flag for alias files; this will comma concatenate like 814038032Speter entries. For example, given the aliases: 814138032Speter list: member1 814238032Speter list: member2 814338032Speter and an alias file declared as: 814438032Speter OAhash:-A /etc/aliases 814538032Speter the final alias inserted will be "list: member1,member2"; 814638032Speter without -A you will get an error on the second and subsequent 814738032Speter alias for "list". Contributed by Bryan Costales of ICSI. 814838032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 814938032Speter Fix a problem that could cause very long addresses to core dump in 815038032Speter some special circumstances. Problem pointed out by Allan 815138032Speter Johannesen. 815238032Speter (Internal change.) Change interface to expand() (macro expansion) 815338032Speter to be simpler and more consistent. 815438032Speter Delete check for funny qf file names. This didn't really give 815538032Speter any extra security and caused some people some problems. 815638032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 815738032Speter at compile time.) Suggested by Kyle Jones of UUNET. 815838032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 815938032Speter merge with DSN code; this is simpler and more consistent. 816038032Speter This may affect some people who have written their own 816138032Speter checkcompat() routine. 816238032Speter (Internal change.) Eliminate `D' line in qf file. The df file 816338032Speter is now assumed to be the same name as the qf file (with 816438032Speter the `q' changed to a `d', of course). 816538032Speter Avoid forking for delivery if all recipient mailers are marked as 816638032Speter "expensive" -- this can be a major cost on some systems. 816738032Speter Essentially, this forces sendmail into "queue only" mode 816838032Speter if all it is going to do is queue anyway. 816938032Speter Avoid sending a null message in some rather unusual circumstances 817038032Speter (specifically, the RCPT command returns a temporary 817138032Speter failure but the connection is lost before the DATA 817238032Speter command). Fix from Scott Hammond of Secure Computing 817338032Speter Corporation. 817438032Speter Change makesendmail to use a somewhat more rational naming scheme: 817538032Speter Makefiles and obj directories are named $os.$rel.$arch, 817638032Speter where $os is the operating system (e.g., SunOS), $rel is 817738032Speter the release number (e.g., 5.3), and $arch is the machine 817838032Speter architecture (e.g., sun4). Any of these can be omitted, 817938032Speter and anything after the first dot in a release number can 818038032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 818138032Speter version used $os.$arch.$rel and was rather less general. 818238032Speter Change makesendmail to do a "make depend" in the target directory 818338032Speter when it is being created. This involves adding an empty 818438032Speter "depend:" entry in most Makefiles. 818538032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 818638032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 818738032Speter of the Finnish Meteorological Institute. 818838032Speter Fix problem that could cause multiple responses to DATA command 818938032Speter on header syntax errors (e.g., lines beginning with colons). 819038032Speter Problem noted by Jens Thomassen of the University of Oslo. 819138032Speter Don't let null bytes in headers cause truncation of the rest of 819238032Speter the header. 819338032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 819438032Speter Increase timeouts on message data puts to allow time for receivers 819538032Speter to canonify addresses in headers on the fly. This is still 819638032Speter a rather ugly heuristic. From Motonori Nakamura. 819738032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 819838032Speter records are not used when canonifying names, and when MX 819938032Speter lookups are done for addressing they must be fully 820038032Speter qualified. This is useful if you have a wildcard MX record, 820138032Speter although it may cause other problems. In general, don't use 820238032Speter wildcard MX records. Patch from Motonori Nakamura. 820338032Speter Eliminate default two-line SMTP greeting message. Instead of 820438032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 820538032Speter is added between the first and second word of the first 820638032Speter line of the greeting message (i.e., immediately after the 820738032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 820838032Speter compile flag. Old sendmails won't see the ESMTP, but that's 820938032Speter acceptable because SIZE was the only useful extension that 821038032Speter old sendmails understand. 821138032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 821238032Speter invoked state dumps. From Masaharu Onishi. 821338032Speter Allow on-line comments in .forward and :include: files; they are 821438032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 821538032Speter is a space or a tab. This is intended for native 821638032Speter representation of non-ASCII sets such as Japanese, where 821738032Speter existing encodings would be unreadable or would lose 821838032Speter data -- for example, 821938032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 822038032Speter (romanized/less information) 822138032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 822238032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 822338032Speter (with MIME encoding, not human readable) 822438032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 822538032Speter (native encoding with ISO-2022-JP) 822638032Speter The last form is human readable in the Japanese environment. 822738032Speter Based on a fix from (surprise!) Motonori Nakamura. 822838032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 822938032Speter messages to that host; these are most frequently associated 823038032Speter with addresses rather than the host, with the exception of 823138032Speter 421 (service shutting down). The effect was to cause queues 823238032Speter to sometimes take an excessive time to flush. Reported by 823338032Speter Robert Sargent of Southern Geographics Technologies and 823438032Speter Eric Prestemon of American University. 823538032Speter Add Nice=N mailer option to set the niceness at which a mailer will 823638032Speter run. This is actually a relative niceness (that is, an 823738032Speter increment on the background value). 823838032Speter Log queue runs that are skipped due to high loads. They are logged 823938032Speter at LOG_INFO priority iff the log level is > 8. Contributed 824038032Speter by Bruce Nagel of Data General. 824138032Speter Allow the error mailer to accept a DSN-style error status code 824238032Speter instead of an sysexits status code in the host part. 824338032Speter Anything with a dot will be interpreted as a DSN-style code. 824438032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 824538032Speter to encode characters that might be munged by an EBCDIC system 824638032Speter in addition to the set required by RFC 1521. The additional 824738032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 824838032Speter (Think of "IBM 360" as the mnemonic for this flag.) 824938032Speter Change check for mailing to files to look for a pathname of [FILE] 825038032Speter rather than looking for the mailer named *file*. The mapping 825138032Speter of leading slashes still goes to the *file* mailer. This 825238032Speter allows you to implement the *file* mailer as a separate 825338032Speter program, for example, to insert a Content-Length: header 825438032Speter or do special security policy. However, note that the usual 825538032Speter initial checking for the file permissions is still done, and 825638032Speter the program in question needs to be very careful about how 825738032Speter it does the file write to avoid security problems. 825838032Speter Be able to read ~root/.forward even if the path isn't accessible to 825938032Speter regular users. This is disrecommended because sendmail 826038032Speter sometimes does not run as root (e.g., when an unsafe option 826138032Speter is specified on the command line), but should otherwise be 826238032Speter safe because .forward files must be owned by the user for 826338032Speter whom mail is being forwarded, and cannot be a symbolic link. 826438032Speter Suggested by Forrest Aldrich of Wang Laboratories. 826538032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 826638032Speter file. This is used for canonifying hostnames when the 826738032Speter service type is "files". 826838032Speter Implement programs on F (read class from file) line. The syntax is 826938032Speter Fc|/path/to/program to read the output from the program 827038032Speter into class "c". 827138032Speter Probe the network interfaces to find alternate names for this 827238032Speter host. Requires the SIOCGIFCONF ioctl call. Code 827338032Speter contributed by SunSoft. 827438032Speter Add "E" configuration line to set or propagate environment 827538032Speter variables into children. "E<envar>" will propagate 827638032Speter the named variable from the environment when sendmail 827738032Speter was invoked into any children it calls; "E<envar>=<value>" 827838032Speter sets the named variable to the indicated value. Any 827938032Speter variables not explicitly named will not be in the child 828038032Speter environment. However, sendmail still forces an 828138032Speter "AGENT=sendmail" environment variable, in part to enforce 828238032Speter at least one environment variable, since many programs and 828338032Speter libraries die horribly if this is not guaranteed. 828438032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 828538032Speter alias databases -- new algorithm looks for the substring 828638032Speter "/yp/" in the file name. This is more portable and involves 828738032Speter less overhead. Suggested by Motonori Nakamura. 828838032Speter Dynamically allocate the queue work list so that you don't lose 828938032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 829038032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 829138032Speter should not need to be changed) and the MaxQueueRunSize option, 829238032Speter which is the absolute maximum number of jobs that will ever 829338032Speter be handled in a single queue run. Based on code contributed 829438032Speter by Brian Coan of the Institute for Global Communications. 829538032Speter Log message when a message is dropped because it exceeds the maximum 829638032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 829738032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 829838032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 829938032Speter of Mark G. Thomas Consulting. 830038032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 830138032Speter OS-dependent defines). The old semantic of -d0.1 to not 830238032Speter run the daemon in background has been moved to -d99.100, 830338032Speter and the old 52.5 flag (to avoid disconnect() from closing 830438032Speter all output files) has been moved to 52.100. This makes 830538032Speter things more consistent (flags below .100 don't change 830638032Speter semantics) and separates out the backgrounding so that 830738032Speter it doesn't happen automatically on other unrelated debugging 830838032Speter flags. 830938032Speter If -t is used but no addresses are found in the header, give an 831038032Speter error message rather than just doing nothing. Fix from 831138032Speter Motonori Nakamura. 831238032Speter On systems (like SunOS) where the effective gid is not necessarily 831338032Speter included in the group list returned by getgroups(), the 831438032Speter `restrictmailq' option could sometimes cause an authorized 831538032Speter user to not be able to use `mailq'. Fix from Charles Hannum 831638032Speter of MIT. 831738032Speter Allow symbolic service names for [IPC] mailers. Suggested by 831838032Speter Gerry Magennis of Logica International. 831938032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 832038032Speter when running DNS. For example, if the name FTP.Foo.ORG is 832138032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 832238032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 832338032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 832438032Speter This is technically illegal under RFC 822 and 1123, but the 832538032Speter IETF is moving toward legalizing it. Note that turning on 832638032Speter this option is not sufficient to guarantee that a downstream 832738032Speter neighbor won't rewrite the address for you. 832838032Speter Add "-m" flag to makesendmail script -- this tells you what object 832938032Speter directory and Makefile it will use, but doesn't actually do 833038032Speter the make. 833138032Speter Do some additional checking on the contents of the qf file to try 833238032Speter to detect attacks against the qf file. In particular, 833338032Speter abort on any line beginning "From ", and add an "end of 833438032Speter file" line -- any data after that line is prohibited. 833538032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 833638032Speter choices. This can be overridden in the Makefile by using 833738032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 833838032Speter (to the extent that we know it) or by defining 833938032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 834038032Speter sendmail 8 to have more consistent installation instructions. 834138032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 834238032Speter of Sun Microsystems. 834338032Speter Improved symbol table hash function from Eric Wassenaar. This one 834438032Speter is at least 50% faster. 834538032Speter Fix problem that didn't notice that timeout on file open was a 834638032Speter transient error. Fix from Larry Parmelee of Cornell 834738032Speter University. 834838032Speter Allow comments (lines beginning with a `#') in files read for 834938032Speter classes. Suggested by Motonori Nakamura. 835038032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 835138032Speter of dropping out entirely. This makes testing some of the 835238032Speter name server lookups easier to deal with when there are 835338032Speter hung servers. From Motonori Nakamura. 835438032Speter Add new ${opMode} macro that is set to the current operation mode 835538032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 835638032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 835738032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 835838032Speter Kind of like queue-only mode (Odq) except it tries to avoid 835938032Speter any external service requests; for dial-on-demand hosts that 836038032Speter want to minimize DNS lookups when mail is being queued. For 836138032Speter this to work you will also have to make sure that gethostbyname 836238032Speter of your local host name does not do a DNS lookup. 836338032Speter Improved handling of "out of space" conditions from John Myers of 836438032Speter Carnegie Mellon. 836538032Speter Improved security for mailing to files on systems that have fchmod(2) 836638032Speter support. 836738032Speter Improve "cannot send message for N days" message -- now says "could 836838032Speter not send for past N days". Suggested by Tom Moore of AT&T 836938032Speter Global Information Solutions. 837038032Speter Less misleading Subject: line on messages sent to postmaster only. 837138032Speter From Motonori Nakamura. 837238032Speter Avoid duplicate error messages on bad command line flags. From 837338032Speter Motonori Nakamura. 837438032Speter Better error message for case where ruleset 0 falls off the end 837538032Speter or otherwise does not resolve to a canonical triple. 837638032Speter Fix a problem that could cause multiple bounce messages if a bad 837738032Speter address was sent along with a good address to an SMTP 837838032Speter site where that SMTP site returned a 4yz code in response 837938032Speter to the final dot of the data. Problem reported by David 838038032Speter James of British Telecom. 838138032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 838238032Speter from Alexander Dupuy of System Management ARTS. 838338032Speter Delete duplicates in MX lists -- believe it or not, there are sites 838438032Speter that list the same host twice in an MX list. This deletion 838538032Speter only works on adjacent preferences, so an MX list that 838638032Speter had A=5, B=10, A=15 would leave both As, but one that had 838738032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 838838032Speter just in case there is something weird I haven't thought of. 838938032Speter Suggested by Barry Shein of Software Tool & Die. 839038032Speter SECURITY: .forward files cannot be symbolic links.

Suggested by Allan Johannesen. 848538032Speter UnixWare 2.0 fixes from Petr Lampa of the Technical 848638032Speter University of Brno (Czech Republic). 848738032Speter KSR OS 1.2.2 support from Todd Miller of the University 848838032Speter of Colorado. 848938032Speter UX4800 support from Kazuhisa Shimizu of NEC. 849038032Speter MAKEMAP: allow -d flag to allow insertion of duplicate aliases 849138032Speter in type ``btree'' maps. The semantics of this are undefined 849238032Speter for regular maps, but it can be useful for the user database. 849338032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 849438032Speter lookups while the rebuild is going on. There is a race 849538032Speter condition between the open(... O_TRUNC ...) and the lock 849638032Speter on the file, but it should be quite small. 849738032Speter SMRSH: sendmail restricted shell added to the release. This can 849838032Speter be used as an alternative to /bin/sh for the "prog" mailer, 849938032Speter giving the local administrator more control over what 850038032Speter programs can be run from sendmail. 850138032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 850238032Speter part of the release proper, and isn't fully supported; in 850338032Speter particular, it does not run on System V based systems and 850438032Speter never will. 850538032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 850638032Speter to allow rmail to compile on systems that don't have 850738032Speter function prototypes and systems that don't have snprintf. 850838032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 850938032Speter lists by transaction delay times so that addresses that 851038032Speter respond quickly get sent first. This is to prevent very 851138032Speter sluggish servers from delaying other peoples' mail. 851238032Speter Contributed by Tony Sanders of BSDI. 851338032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 851438032Speter of BSDI. This has a lot of comments to help people out. 851538032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 851638032Speter put this on the m4 command line. On GNU m4 (which 851738032Speter supports the __file__ primitive) you can run m4 in an 851838032Speter arbitrary directory -- use either: 851938032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 852038032Speter or 852138032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 852238032Speter On other versions of m4 that don't support __file__, you 852338032Speter can use: 852438032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 852538032Speter (Note the trailing slash on the _CF_DIR_ definition.) 852638032Speter Old versions of m4 will default to _CF_DIR_=.. for back 852738032Speter compatibility. 852838032Speter CONFIG: fix mail from <> so it will properly convert to 852938032Speter MAILER-DAEMON on local addresses. 853038032Speter CONFIG: fix code that was supposed to catch colons in host 853138032Speter names. Problem noted by John Gardiner Myers of CMU. 853238032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 853338032Speter From Paul Riddle of the University of Maryland, Baltimore 853438032Speter County. 853538032Speter CONFIG: Catch and reject "." as a host address. 853638032Speter CONFIG: Generalize domaintable to look up all domains, not 853738032Speter just unqualified ones. 853838032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 853938032Speter was never used and didn't work anyway. 854038032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 854138032Speter and d on all mailers in the UUCP class. 854238032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 854338032Speter look for an alias for "user+detail", then for "user+*", and 854438032Speter finally for "user". This is intended for forwarding mail 854538032Speter for system aliases such as root and postmaster to a 854638032Speter centralized hub. 854738032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 854838032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 854938032Speter The F=8 flag is also set on the "relay" mailer, since 855038032Speter this is expected to be another sendmail. 855138032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 855238032Speter the name of the UUCP_RELAY -- in some cases, this is the 855338032Speter wrong value (e.g., when we have local UUCP connections), 855438032Speter and this can create unreplyable addresses. From Chip 855538032Speter Rosenthal of Unicom. 855638032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 855764562Sgshapiro Received: header inserted into all messages. Suggested by 855838032Speter Gary Mills of the University of Manitoba. 855938032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 856043730Speter to get the old behavior. I did this upon observing 856138032Speter that almost everyone needed this feature, and that the 856238032Speter concept I was trying to make happen didn't work with 856338032Speter some user agents anyway. FEATURE(notsticky) still works, 856438032Speter but it is a no-op. 856538032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 856638032Speter names are sent, rather than immediately diagnosing them 856738032Speter as User Unknown. 856838032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 856938032Speter and RELAY_MAILER_ARGS to set the arguments for the 857038032Speter indicated mailers. All default to "IPC $h". Patch from 857138032Speter Larry Parmelee of Cornell University. 857238032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 857338032Speter on the client side" and F=P to get an appropriate 857438032Speter return-path. From Kimmo Suominen. 857538032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 857638032Speter as the local mailer. For addresses of the form "user+detail" 857738032Speter the "detail" part is passed to procmail via the -a flag. 857838032Speter Contributed by Kimmo Suominen. 857938032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 858038032Speter use from mailertables. This lets you execute arbitrary 858138032Speter procmail scripts. Contributed by Kimmo Suominen. 858238032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 858338032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 858438032Speter Paul Southworth of CICNet Systems Support. 858538032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 858638032Speter This causes the null return path to be rewritten as 858738032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 858838032Speter From Michael Hohmuth of Technische Universitat Dresden. 858938032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 859038032Speter list us as the best possible MX record to be treated as 859138032Speter though they were local (essentially, assume that they 859238032Speter are included in $=w). This can cause additional DNS 859338032Speter traffic, but is easier to administer if this fits your 859438032Speter local model. It does not work reliably if there are 859538032Speter multiple hosts that share the best MX preference. 859638032Speter Code contributed by John Oleynick of Rutgers. 859738032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 859838032Speter SHell) instead of /bin/sh as the program used for delivery 859938032Speter to programs. If an argument is included, it is used as 860038032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 860138032Speter assumed. 860238032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 860338032Speter size of messages to the local and procmail mailers 860438032Speter respectively. Contributed by Brad Knowles of the Defense 860538032Speter Information Systems Agency. 860638032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 860738032Speter (just like text outside of angle brackets) in order to 860838032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 860938032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 861038032Speter any real systems any more) and tweak the DOMAIN macro 861138032Speter so that it is less likely that users will accidentally use 861238032Speter the Berkeley defaults. Also, create some generic files 861338032Speter that really can be used in the real world. 861438032Speter CONFIG: Add new configuration macros to set character sets for 861538032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 861638032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 861738032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 861838032Speter The old name will still be accepted for a while at least. 861938032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 862038032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 862138032Speter As with all relays, it can be ``mailer:hostname''. Suggested 862238032Speter by Scott Hutton. 862338032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 862438032Speter by Barb Dijker of Labyrinth Computer Services. 862538032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 862638032Speter performance for large alias files, and this confused many 862738032Speter people. 862838032Speter CONFIG: Add confCF_VERSION to append local information to the 862938032Speter configuration version number displayed during SMTP startup. 863038032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 863138032Speter would only work when locally addressed. Fix from 863238032Speter Edvard Tuinder of Cistron Internet Services. 863338032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 863443730Speter "n" (CheckAliases) is set when rebuilding alias database. 863538032Speter Based on code contributed by Claude Marinier. 863638032Speter CONFIG: Allow mailertable to have values of the form 863738032Speter ``error:code message''. The ``code'' is a status code 863838032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 863938032Speter Contributed by David James <dwj@agw.bt.co.uk>. 864038032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 864138032Speter sender domains that will be replaced with the masquerade name. 864238032Speter These domains will not be treated as local, but if mail passes 864338032Speter through with sender addresses in those domains they will be 864438032Speter replaced by the masquerade name. These can also be specified 864538032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 864638032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 864738032Speter as well as the header. Substantial improvements to this 864838032Speter code were contributed by Per Hedeland. 864938032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 865038032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 865138032Speter by Kimmo Suominen. 865238032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 865338032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 865438032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 865538032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 865638032Speter UUCP addressing.

This caused UnixWare 879938032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 880038032Speter Novell Labs Europe. 880138032Speter Fix problem with static linking of local getopt routine when 880238032Speter using GNU's ld command. Fix from John Kennedy of 880338032Speter Cal State Chico. 880438032Speter It was possible to turn off privacy flags. Problem noted by 880538032Speter *Hobbit*. 880638032Speter Be more paranoid about writing files. Suggestions by *Hobbit* 880738032Speter and Liudvikas Bukys. 880838032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 880938032Speter from Spider Boardman. 881038032Speter CONFIG: No changes (version number only, to keep it in sync 881138032Speter with the binaries). 881238032Speter 881364562Sgshapiro8.6.10/8.6.10 1995/02/10 881438032Speter SECURITY: Diagnose bogus values to some command line flags that 881538032Speter could allow trash to get into headers and qf files. 881638032Speter Validate the name of the user returned by the IDENT protocol. 881738032Speter Some systems that really dislike IDENT send intentionally 881838032Speter bogus information. Problem pointed out by Michael Bushnell 881938032Speter of the Free Software Foundation. Has some security 882038032Speter implications. 882138032Speter Fix a problem causing error messages about DNS problems when 882238032Speter the host name contained a percent sign to act oddly 882338032Speter because it was passed as a printf-style format string. 882438032Speter In some cases this could cause core dumps. 882538032Speter Avoid possible buffer overrun in returntosender() if error 882638032Speter message is quite long. From Fletcher Mattox of the 882738032Speter University of Texas. 882838032Speter Fix a problem that would silently drop "too many hops" error 882938032Speter messages if and only if you were sending to an alias. 883038032Speter From Jon Giltner of the University of Colorado and 883138032Speter Dan Harton of Oak Ridge National Laboratory. 883238032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 883338032Speter set and e->e_message was null. Fix from Bruce Nagel of 883438032Speter Data General. 883538032Speter Fix problem that can still cause df files to be left around 883638032Speter after "hop count exceeded" messages. Fix from Andrew 883738032Speter Chang and Shau-Ping Lo of SunSoft. 883838032Speter Fix a problem that can cause buffer overflows on very long 883938032Speter user names (as might occur if you piped to a program 884038032Speter with a lot of arguments). 884138032Speter Avoid returning an error and re-queueing if the host signature 884238032Speter is null; this can occur on addresses like ``user@.''. 884338032Speter Problem noted by Wesley Craig and the University of 884438032Speter Michigan. 884538032Speter Avoid possible calls to malloc(0) if MCI caching is turned 884638032Speter off. Bug fix from Pierre David of the Laboratoire 884738032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 884838032Speter Universite de Versailles - St Quentin, and Jacky 884938032Speter Thibault. 885038032Speter Make a local copy of the line being sent via senttolist() -- in 885138032Speter some cases, buffers could get trashed by map lookups 885238032Speter causing it to do unexpected things. This also simplifies 885338032Speter some of the map code. 885438032Speter CONFIG: No changes (version number only, to keep it in sync 885538032Speter with the binaries). 885638032Speter 885764562Sgshapiro8.6.9/8.6.9 1994/04/19 885838032Speter Do all mail delivery completely disconnected from any terminal. 885938032Speter This provides consistency with daemon delivery and 886038032Speter may have some security implications. 886138032Speter Make sure that malloc doesn't get called with zero size, 886238032Speter since that fails on some systems. Reported by Ed 886338032Speter Hill of the University of Iowa. 886438032Speter Fix multi-line values for $e (SMTP greeting message). Reported 886538032Speter by Mike O'Connor of Ford Motor Company. 886638032Speter Avoid syserr if no NIS domain name is defined, but the map it 886738032Speter is trying to open is optional. From Win Bent of USC. 886838032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 886938032Speter Hesiod support for UDB from Todd Miller of the University of 887038032Speter Colorado. Use "hesiod" as the service name in the U 887138032Speter option. 887238032Speter Fix a problem that failed to set the "authentic" host name (that 887338032Speter is, the one derived from the socket info) if you called 887438032Speter sendmail -bs from inetd. Based on code contributed by 887538032Speter Todd Miller (this problem was also reported by Guy Helmer 887638032Speter of Dakota State University). This also fixes a related 887738032Speter problem reported by Liudvikas Bukys of the University of 887838032Speter Rochester. 887938032Speter Parameterize "nroff -h" in all the Makefiles so people with 888038032Speter variant versions can use them easily. Suggested by 888138032Speter Peter Collinson of Hillside Systems. 888238032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 888338032Speter spaces between parameters instead of one. Reported by 888438032Speter Valdis Kletnieks of Virginia Tech. 888538032Speter Reduce the number of system calls during message collection by 888638032Speter using global timeouts around the collect() loop. This 888738032Speter code was contributed by Eric Wassenaar. 888838032Speter If the initial hostname name gathering results in a name 888938032Speter without a dot (usually caused by NIS misconfiguration) 889038032Speter and BIND is compiled in, directly access DNS to get 889138032Speter the canonical name. This should make life easier for 889238032Speter Solaris systems. If it still can't be resolved, and 889338032Speter if the name server is listed as "required", try again 889438032Speter in 30 seconds. If that also fails, exit immediately to 889538032Speter avoid bogus "config error: mail loops back to myself" 889638032Speter messages. 889738032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 889838032Speter message to explain how much space was available and 889938032Speter sound a bit less threatening. Suggested by Stan Janet 890038032Speter of the National Institute of Standards and Technology. 890138032Speter If mail is delivered to an alias that has an owner, deliver any 890238032Speter requested return-receipt immediately, and strip the 890338032Speter Return-Receipt-To: header from the subsequent message. 890438032Speter This prevents a certain class of denial of service 890538032Speter attack, arguably gives more reasonable semantics, and 890638032Speter moves things more towards what will probably become a 890738032Speter network standard. Suggested by Christopher Davis of 890838032Speter Kapor Enterprises. 890938032Speter Add a "noreceipts" privacy flag to turn off all return receipts 891038032Speter without recompiling. 891138032Speter Avoid printing ESMTP parameters as part of the error message 891238032Speter if there are errors during parsing. This change is 891338032Speter purely cosmetic. 891438032Speter Avoid sending out error messages during the collect phase of 891538032Speter SMTP; there is an MVS mailer from UCLA that gets 891638032Speter confused by this. Of course, I think it's their bug.... 891738032Speter Check for the $j macro getting undefined, losing a dot, or getting 891838032Speter lost from $=w in the daemon before accepting a connection; 891938032Speter if it is, it dumps state, prints a LOG_ALERT message, 892038032Speter and drops core for debugging. This is an attempt to 892138032Speter track down a bug that I thought was long since gone. 892238032Speter If you see this, please forward the log fragment to 892338032Speter sendmail@sendmail.ORG. 892438032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 892538032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 892638032Speter Wolfhugel. 892738032Speter Instead of trying to truncate the listen queue for the server 892838032Speter SMTP port when the load average is too high, just close 892938032Speter the port completely and reopen it later as needed. 893038032Speter This ensures that the other end gets a quick "connection 893138032Speter refused" response, and that the connection can be 893238032Speter recovered later. In particular, some socket emulations 893338032Speter seem to get confused if you tweak the listen queue 893438032Speter size around and can never start listening to connections 893538032Speter again. The down side is that someone could start up 893638032Speter another daemon process in the interim, so you could 893738032Speter have multiple daemons all not listening to connections; 893838032Speter this could in turn cause the sendmail.pid file to be 893938032Speter incorrect. A better approach might be to accept the 894038032Speter connection and give a 421 code, but that could break 894143730Speter other mailers in mysterious ways and have paging behavior 894238032Speter implications. 894338032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 894438032Speter set debugging on the wrong socket. From Eric Wassenaar. 894538032Speter When creating a df* temporary file, be sure you truncate any 894638032Speter existing data in the file -- otherwise system crashes 894738032Speter and the like could result in extra data being sent. 894838032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 894938032Speter doc directory. This includes some additional 895038032Speter information. 895138032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 895238032Speter of recipient envelope addresses. This should have been 895338032Speter handled by the $&h trick, but broke if people were 895438032Speter mixing domainized and UUCP addresses. They should 895538032Speter probably have converted all the way over to uucp-uudom 895638032Speter instead of uucp-{new,old}, but the failure mode was to 895738032Speter loop the mail, which was bad news. 895838032Speter Portability fixes: 895938032Speter Newer BSDI systems (several people). 896038032Speter Older BSDI systems from Christophe Wolfhugel. 896138032Speter Intergraph CLIX, from Paul Southworth of CICNet. 896238032Speter UnixWare, from Evan Champion. 896338032Speter NetBSD from Adam Glass. 896438032Speter Solaris from Quentin Campbell of the University of 896538032Speter Newcastle upon Tyne. 896638032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 896738032Speter Corporation. 896838032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 896938032Speter SunOS (it has setsid() and setvbuf() calls) from 897038032Speter Jonathan Kamens of OpenVision Technologies. 897138032Speter HP-UX from Tor Lillqvist. 897238032Speter New Files: 897338032Speter src/Makefile.CLIX 897438032Speter src/Makefile.NCR3000 897538032Speter doc/changes/Makefile 897638032Speter doc/changes/changes.me 897738032Speter doc/changes/changes.ps 897838032Speter 897964562Sgshapiro8.6.8/8.6.6 1994/03/21 898038032Speter SECURITY: it was possible to read any file as root using the 898138032Speter E (error message) option. Reported by Richard Jones; 898238032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 898338032Speter 898464562Sgshapiro8.6.7/8.6.6 1994/03/14 898538032Speter SECURITY: it was possible to get root access by using weird 898638032Speter values to the -d flag. Thanks to Alain Durand of 898738032Speter INRIA for forwarding me the notice from the bugtraq 898838032Speter list. 898938032Speter 899064562Sgshapiro8.6.6/8.6.6 1994/03/13 899138032Speter SECURITY: the ability to give files away on System V-based 899238032Speter systems proved dangerous -- don't run as the owner 899338032Speter of a :include: file on a system that allows giveaways. 899438032Speter Unfortunately, this also applies to determining a 899538032Speter valid shell. 899638032Speter IMPORTANT: Previous versions weren't expiring old connections 899738032Speter in the connection cache for a long time under some 899838032Speter circumstances. This could result in resource exhaustion, 899938032Speter both at your end and at the other end. This checks the 900038032Speter connections for timeouts much more frequently. From 900138032Speter Doug Anderson of NCSC. 900238032Speter Fix a glitch that snuck in that caused programs to be run as 900338032Speter the sender instead of the recipient if the mail was 900438032Speter from a local user to another local user. From 900538032Speter Motonori Nakamura of Kyoto University. 900638032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 900738032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 900838032Speter Bryan Costales of ICSI. 900938032Speter Change the method used to declare the "statfs" availability; 901038032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 901138032Speter tweaking in conf.c, there is a single #define called 901238032Speter SFS_TYPE which takes on one of six values (SFS_NONE 901338032Speter for no statfs availability, SFS_USTAT for the ustat(2) 901438032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 901538032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 901638032Speter statfs(2) call with the declarations in <sys/vfs.h>, 901738032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 901838032Speter Fix glitch in NetInfo support that could return garbage if 901938032Speter there was no "/locations/sendmail" property. From 902038032Speter David Meyer of the University of Virginia. 902138032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 902238032Speter to allow Linux to turn it off even though it is a 902338032Speter BSD-like system. 902438032Speter Allow setting of "ident" timeout to zero to turn off the ident 902538032Speter protocol entirely. 902638032Speter Make 7-bit stripping local to a connection (instead of to a 902738032Speter mailer); this allows you to specify that SMTP is a 902838032Speter 7-bit channel, but revert to 8-bit should it advertise 902938032Speter that it supports 8BITMIME. You still have to specify 903038032Speter mailer flag 7 to get this stripping at all. 903138032Speter Improve makesendmail script so it handles more cases automatically. 903238032Speter Tighten up restrictions on taking ownership of :include: files 903338032Speter to avoid problems on systems that allow you to give away 903438032Speter files. 903538032Speter Fix a problem that made it impossible to rebuild the alias 903638032Speter file if it was on a read-only file system. From 903738032Speter Harry Edmon of the University of Washington. 903838032Speter Improve MX randomization function. From John Gardiner Myers 903938032Speter of CMU. 904038032Speter Fix a minor glitch causing a bogus message to be printed (used 904138032Speter %s instead of %d in a printf string for the line number) 904238032Speter when a bad queue file was read. From Harry Edmon. 904338032Speter Allow $s to remain NULL on locally generated mail. I'm not 904438032Speter sure this is necessary, but a lot of people have complained 904538032Speter about it, and there is a legitimate question as to whether 904638032Speter "localhost" is legal as an 822-style domain. 904738032Speter Fix a problem with very short line lengths (mailer L= flag) in 904838032Speter headers. This causes a leading space to be added onto 904938032Speter continuation lines (including in the body!), and also 905038032Speter tries to wrap headers containing addresses (From:, To:, 905138032Speter etc) intelligently at the shorter line lengths. Problem 905238032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 905338032Speter Log the real user name when logging syserrs, since these can have 905438032Speter security implications. Suggested by several people. 905538032Speter Fix address logging of cached connections -- it used to always 905638032Speter log the numeric address as zero. This is a somewhat 905738032Speter bogus implementation in that it does an extra system 905838032Speter call, but it should be an inexpensive one. Fix from 905938032Speter Motonori Nakamura. 906038032Speter Tighten up handling of short syslog buffers even more -- there 906138032Speter were cases where the outgoing relay= name was too long 906238032Speter to share a line with delay= and mailer= logging. 906338032Speter Limit the overhead on split envelopes to one open file descriptor 906438032Speter per envelope -- previously the overhead was three 906538032Speter descriptors. This was in response to a problem reported 906638032Speter by P{r (Pell) Emanuelsson. 906738032Speter Fixes to better handle the case of unexpected connection closes; 906838032Speter this redirects the output to the transcript so the info 906938032Speter is not lost. From Eric Wassenaar. 907038032Speter Fix potential string overrun if you macro evaluate a string that 907138032Speter has a naked $ at the end. Problem noted by James Matheson 907238032Speter <jmrm@eng.cam.ac.uk>. 907338032Speter Make default error number on $#error messages 553 (``Requested 907438032Speter action not taken: mailbox name not allowed'') instead of 907538032Speter 501 (``Syntax error in parameters or arguments'') to 907638032Speter avoid bogus "protocol error" messages. 907738032Speter Strip off any existing trailing dot on names during $[ ... $] 907838032Speter lookup. This prevents it from ending up with two dots 907938032Speter on the end of dot terminated names. From Wesley Craig 908038032Speter of the University of Michigan and Bryan Costales of ICSI. 908138032Speter Clean up file class reading so that the debugging information is 908238032Speter more informative. It hadn't been using setclass, so you 908338032Speter didn't see the class items being added. 908438032Speter Avoid core dump if you are running a version of sendmail where 908538032Speter NIS is compiled in, and you specify an NIS map, but 908638032Speter NIS is not running. Fix from John Oleynick of 908738032Speter Rutgers. 908838032Speter Diagnose bizarre case where res_search returns a failure value, 908938032Speter but sets h_errno to a success value. 909038032Speter Make sure that "too many hops" messages are considered important 909138032Speter enough to send an error to the Postmaster (that is, the 909238032Speter address specified in the P option). This fix should 909338032Speter help problems that cause the df file to be left around 909438032Speter sometimes -- unfortunately, I can't seem to reproduce 909538032Speter the problem myself. 909638032Speter Avoid core dump (null pointer reference) on EXPN command; this 909738032Speter only occurred if your log level was set to 10 or higher 909838032Speter and the target account was an alias or had a .forward file. 909938032Speter Problem noted by Janne Himanka. 910038032Speter Avoid "denial of service" attacks by someone who is flooding your 910138032Speter SMTP port with bad commands by shutting the connection 910238032Speter after 25 bad commands are issued. From Kyle Jones of 910338032Speter UUNET. 910438032Speter Fix core dump on error messages with very long "to" buffers; 910538032Speter fmtmsg overflows the message buffer. Fixed by trimming 910638032Speter the to address to 203 characters. Problem reported by 910738032Speter John Oleynick. 910838032Speter Fix configuration for HASFLOCK -- there were some spots where 910938032Speter a #ifndef was incorrectly #ifdef. Pointed out by 911038032Speter George Baltz of the University of Maryland. 911138032Speter Fix a typo in savemail() that could cause the error message To: 911238032Speter lists to be incorrect in some places. From Motonori 911338032Speter Nakamura. 911438032Speter Fix a glitch that can cause duplicate error messages on split 911538032Speter envelopes where an address on one of the lists has a 911638032Speter name server failure. Fix from Voradesh Yenbut of the 911738032Speter University of Washington. 911838032Speter Fix possible bogus pointer reference on ESMTP parameters that 911938032Speter don't have an ``=value'' part. 912038032Speter CNAME loops caused an error message to be generated, but also 912138032Speter re-queued the message. Changed to just re-queue the 912238032Speter message (it's really hard to just bounce it because 912338032Speter of the weird way the name server works in the presence 912438032Speter of CNAME loops). Problem noted by James M.R.Matheson 912538032Speter of Cambridge University. 912638032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 912738032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 912838032Speter user name. Suggested by Andreas Stolcke of ICSI. 912938032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 913038032Speter override it easily in the Makefile -- that is, you can 913138032Speter turn it off using -DNAMED_BIND=0. 913238032Speter If a gethostbyname(...) of an address with a trailing dot fails, 913338032Speter try it without the trailing dot. This is because if 913438032Speter you have a version of gethostbyname() that falls back 913538032Speter to NIS or the /etc/hosts file it will fail to find 913638032Speter perfectly reasonable names that just don't happen to 913738032Speter be dot terminated in the hosts file. You don't want to 913838032Speter strip the dot first though because we're trying to ensure 913938032Speter that country names that match one of your subdomains get 914038032Speter a chance. 914138032Speter PRALIASES: fix bogus output on non-null-terminated strings. 914238032Speter From Bill Gianopoulos of Raytheon. 914338032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 914438032Speter This was in code intended to only catch the self-literal 914538032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 914638032Speter IP address), but the code was broken. However, it will 914738032Speter still do this if $M is defined; this is necessary to 914838032Speter get client configurations to work (sigh). Note that this 914938032Speter means that $M overrides :mailname entries in the user 915038032Speter database! Problem noted by Paul Southworth. 915138032Speter CONFIG: Fix definition of Solaris help file location. From 915238032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 915338032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 915438032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 915538032Speter and USENET_MAILER_MAX to tweak the maximum message 915638032Speter size for various mailers. 915738032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 915838032Speter instead of assuming that it is "inews" for consistency 915938032Speter with other mailers. From Michael Corrigan of UC San Diego. 916038032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 916138032Speter qualify the address in the SMTP envelope as user@{relay|hub} 916238032Speter instead of user@$j. From Bill Wisner of The Well. 916338032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 916438032Speter CONFIG: Don't turn off case mapping of user names in the local 916538032Speter mailer for IRIX. This was different than most every other 916638032Speter system. 916738032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 916838032Speter envelope. Noted by Thierry Besancon 916938032Speter <besancon@excalibur.ens.fr>. 917038032Speter CONFIG: Don't include -z by default on uux line -- most systems 917138032Speter don't want it set by default. Pointed out by Philippe 917238032Speter Michel of Thomson CSF. 917338032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 917438032Speter host name was foo.bar.ray.com and you matched against 917538032Speter ".ray.com", the old implementation bound %1 to "bar" 917638032Speter instead of "foo.bar". Also, allow "." in the mailertable 917738032Speter to match anything -- essentially, take over SMART_HOST. 917838032Speter This also moves matching of explicit local host names 917938032Speter before the mailertable so they don't have to be special 918038032Speter cased in the mailertable data. Reported by Bill 918138032Speter Gianopoulos of Raytheon; the fix for the %1 binding 918238032Speter problem was contributed by Nicholas Comanos of the 918338032Speter University of Sydney. 918438032Speter CONFIG: Don't include "root" in class $=L (users to deliver 918538032Speter locally, even if a hub or relay exists) by default. 918638032Speter This is because of the known bug where definition of 918738032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 918838032Speter both and deliver into the local mailbox. 918938032Speter CONFIG: Move up bitdomain and uudomain handling so that they 919038032Speter are done before .UUCP class matching; uudomain was 919138032Speter reported as ineffective before. This also frees up 919238032Speter diversion 8 for future use. Problem reported by Kimmo 919338032Speter Suominen. 919438032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 919538032Speter into host names. As pointed out by Jonathan Kamens, 919638032Speter these are often used because either the forward or reverse 919738032Speter mapping is broken; this translation makes it broken again. 919838032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 919938032Speter Suominen. 920038032Speter Portability fixes: 920138032Speter Unicos from David L.

From 922538032Speter Bob Campbell at U.C. Berkeley. 922638032Speter Security fix: group ids were not completely set when programs 922738032Speter were invoked. This caused programs to have group 922838032Speter permissions they should not have had (usually group 922938032Speter daemon instead of their own group). In particular, 923038032Speter Perl scripts would refuse to run. 923138032Speter Security: check to make sure files that are written are not 923238032Speter symbolic links (at least under some circumstances). 923338032Speter Although this does not respond to a specific known 923438032Speter attack, it's just a good idea. Suggested by 923538032Speter Christian Wettergren. 923638032Speter Security fix: if a user had an NFS mounted home directory on 923738032Speter a system with a restricted shell listed in their 923838032Speter /etc/passwd entry, they could still execute any 923938032Speter program by putting that in their .forward file. 924038032Speter This fix prevents that by insisting that their shell 924138032Speter appear in /etc/shells before allowing a .forward to 924238032Speter execute a program or write a file. You can disable 924338032Speter this by putting "*" in /etc/shells. It also won't 924438032Speter permit world-writable :include: files to reference 924538032Speter programs or files (there's no way to disable this). 924643730Speter These behaviors are only one level deep -- for 924738032Speter example, it is legal for a world-writable :include: 924838032Speter file to reference an alias that writes a file, on 924938032Speter the assumption that the alias file is well controlled. 925038032Speter Security fix: root was not treated suspiciously enough when 925138032Speter looking into subdirectories. This would potentially 925238032Speter allow a cracker to examine files that were publicly 925338032Speter readable but in a non-publicly searchable directory. 925438032Speter Fix a problem that causes an error on QUIT on a cached 925538032Speter connection to create problems on the current job. 925638032Speter These are typically unrelated, so errors occur in 925738032Speter the wrong place. 925838032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 925938032Speter runs more responsive to load average, and fixes a 926038032Speter problem that ignored the load average in locally 926138032Speter generated mail. From Eric Wassenaar. 926238032Speter Fix possible core dump on aliases with null LHS. From 926338032Speter John Orthoefer of BB&N. 926438032Speter Revert to using flock() whenever possible -- there are just 926538032Speter too many bugs in fcntl() locking, particularly over 926638032Speter NFS, that cause sendmail to fail in perverse ways. 926738032Speter Fix a bug that causes the connection cache to get confused 926838032Speter when sending error messages. This resulted in 926938032Speter "unexpected close" messages. It should fix itself 927038032Speter on the following queue run. Problem noted by 927138032Speter Liudvikas Bukys of the University of Rochester. 927238032Speter Include $k in $=k as documented in the Install & Op Guide. 927338032Speter This seems odd, but it was documented.... From 927438032Speter Michael Corrigan of UCSD. 927538032Speter Fix problem that caused :include:s from alias files to be 927638032Speter forced to be owned by root instead of daemon 927738032Speter (actually DefUid). From Tim Irvin. 927838032Speter Diagnose unrecognized I option values -- from Mortin Forssen 927938032Speter of the Chalmers University of Technology. 928038032Speter Make "error" mailer work consistently when there is no error 928138032Speter code associated with it -- previously it returned OK 928238032Speter even though there was a real problem. Now it assumes 928338032Speter EX_UNAVAILABLE. 928438032Speter Fix bug that caused the last header line of messages that had 928538032Speter no body and which were terminated with EOF instead of 928638032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 928738032Speter Fix core dump on SMTP mail to programs that failed -- it tried 928838032Speter to go to a "next MX host" when none existed, causing 928938032Speter a core dump. From der Mouse at McGill University. 929038032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 929138032Speter this makes it easier to turn it off (using 929238032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 929338032Speter Fix YP_MASTER_NAME store to use the unupdated result of 929438032Speter gethostname() (instead of myhostname(), which tries 929538032Speter to fully qualify the name) to be consistent with 929638032Speter SunOS. If your hostname is unqualified, this fixes 929738032Speter transfers to slave servers. Bug noted by Keith 929838032Speter McMillan of Ameritech Services, Inc. 929938032Speter Fix Ultrix problem: gethostbyname() can return a very large 930038032Speter (> 500) h_length field, which causes the sockaddr 930138032Speter to be trashed. Use the size of the sockaddr instead. 930238032Speter Fix from Bob Manson of Ohio State. 930338032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 930438032Speter defined -- this confuses gethostbyname on hosts 930538032Speter file lookups, which doesn't understand the trailing 930638032Speter dot convention. 930738032Speter Log SMTP server subprocesses that die with a signal instead 930838032Speter of from a clean exit. 930938032Speter If you don't have option "I" set, don't assume that a DNS 931038032Speter "host unknown" message is authoritative -- it 931138032Speter might still be found in /etc/hosts. 931238032Speter Fix a problem that would cause Deferred: messages to be sent 931338032Speter as the subject of an error message, even though the 931438032Speter actual cause of a message was more severe than that. 931538032Speter Problem noted by Chris Seabrook of OSSI. 931638032Speter Fix race condition in DBM alias file locking. From Kyle 931738032Speter Jones of UUNET. 931838032Speter Limit delivery syslog line length to avoid bugs in some 931938032Speter versions of syslog(3). This adds a new compile time 932038032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 932138032Speter University, which is in turn derived from IDA. 932238032Speter Fix quotes inside of comments in addresses -- previously 932338032Speter it insisted that they be balanced, but the 822 spec 932438032Speter says that they should be ignored. 932538032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 932638032Speter debugging). This also evaluates ruleset 89, if set 932738032Speter (with the null input), and logs the result. This 932838032Speter should be used sparingly, since the rewrite process 932938032Speter is not reentrant. 933038032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 933138032Speter documented in the Bat Book. 933238032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 933338032Speter return an error message and did not requeue the message. 933438032Speter Fix based on code from Roland Dirlewanger of 933538032Speter Reseau Regional Aquarel, Bordeaux, France. 933638032Speter Fix a problem that caused a seg fault if you got a 421 error 933738032Speter code during some parts of connection initialization. 933838032Speter I've only seen this when talking to buggy mailers on 933938032Speter the other end, but it shouldn't give a seg fault in 934038032Speter any case. From Amir Plivatsky. 934138032Speter Fix core dump caused by a ruleset call that returns null. 934238032Speter Fix from Bryan Costales of ICSI. 934338032Speter Full-Name: field was being ignored.

Noted by William C Fenner of 938238032Speter the NRL Connection Machine Facility. 938338032Speter Fix a problem that could cause a core dump if the input sequence 938438032Speter had (or somehow acquired) a \231 character. 938538032Speter Make sure that route-addrs always have <angle brackets> around 938638032Speter them in non-SMTP envelopes (SMTP envelopes already do 938738032Speter this properly). 938838032Speter Avoid weird headers on unbalanced punctuation of the form: 938938032Speter ``Joe User <user)'' -- this caused reference to the 939038032Speter null macro. Fix from Rick McCarty of IO.COM. 939138032Speter Fix a problem that caused an alias "user: user@local.host" to 939238032Speter not have the QNOTREMOTE bit set; this caused configs 939338032Speter to act as if FEATURE(notsticky) was defined even when 939438032Speter it was not. The effect of the problem was to make it 939538032Speter very hard to to set up satellite sites that had a few 939638032Speter local accounts, with everything else forwarded to a 939738032Speter corporate hub. Reported by Detlef Drewanz of the 939838032Speter University of Rostock and Mark Frost of NCD. 939938032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 940038032Speter addresses. This is more efficient (fewer name server 940138032Speter calls) and fixes certain unusual configurations, such 940238032Speter as those that have ruleset 4 do something that is 940338032Speter non-idempotent unless a mailer-specific ruleset did 940438032Speter something else.

Briefly, if you are sending to host 947338032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 947438032Speter "foo!baz" remains "foo!baz", and anything else has 947538032Speter the local name prepended. 947638032Speter CONFIG: portability fixes for HP-UX. 947738032Speter DOC: several minor problems fixed in the Install & Op Guide. 947838032Speter MAKEMAP: fix core dump problem on lines that are too long or 947938032Speter which lack newline. From Mark Delany. 948038032Speter MAILSTATS: print sums of columns (total messages & kbytes 948138032Speter in and out of the system). From Tom Ferrin of UC 948238032Speter San Francisco Computer Graphics Lab. 948338032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 948438032Speter On HP-UX, /etc/sendmail.cf has been moved to 948538032Speter /usr/lib/sendmail.cf to match HP sendmail. 948638032Speter Permissions have been tightened up on world-writable 948738032Speter :include: files and accounts that have shells 948838032Speter that are not listed in /etc/shells. This may 948938032Speter cause some .forward files that have worked 949038032Speter before to start failing. 949138032Speter SIGUSR1 dumps some state to the log. 949238032Speter NEW FILES: 949338032Speter src/Makefile.DGUX 949438032Speter src/Makefile.Dynix 949538032Speter src/Makefile.FreeBSD 949638032Speter src/Makefile.Mach386 949738032Speter src/Makefile.NetBSD 949838032Speter src/Makefile.RISCos 949938032Speter src/Makefile.SCO 950038032Speter src/Makefile.SVR4 950138032Speter src/Makefile.Titan 950238032Speter cf/mailer/pop.m4 950338032Speter cf/ostype/bsdi1.0.m4 950438032Speter cf/ostype/dgux.m4 950538032Speter cf/ostype/dynix3.2.m4 950638032Speter cf/ostype/sco3.2.m4 950738032Speter makemap/Makefile.dist 950838032Speter praliases/Makefile.dist 950938032Speter 951064562Sgshapiro8.6.4/8.6.4 1993/10/31 951138032Speter Repair core-dump problem (write to read-only memory segment) 951238032Speter if you fall back to the return-to-Postmaster case in 951338032Speter savemail. Problem reported by Richard Liu. 951438032Speter Immediately diagnose bogus sender addresses in SMTP. This 951538032Speter makes quite certain that crackers can't use this 951638032Speter class of attack. 951738032Speter Reliability Fix: check return value from fclose() and fsync() 951838032Speter in a few critical places. 951938032Speter Minor problem in initsys() that reversed a condition for 952038032Speter redirecting the output channel on queue runs. It's 952138032Speter not clear this code even does anything. From Eric 952238032Speter Wassenaar of the Dutch National Institute for Nuclear 952338032Speter and High-Energy Physics. 952438032Speter Fix some problems that caused queue runs to do "too much work", 952538032Speter such as double-reading the Errors-To: header. From 952638032Speter Eric Wassenaar. 952738032Speter Error messages on writing the temporary file (including the 952838032Speter data file) were getting suppressed in SMTP -- this 952938032Speter fix causes them to be properly reported. From Eric 953038032Speter Wassenaar. 953138032Speter Some changes to support AF_UNIX sockets -- this will only 953238032Speter really become relevant in the next release, but some 953338032Speter people need it for local patches. From Michael 953438032Speter Corrigan of UC San Diego. 953538032Speter Use dynamically allocated memory (instead of static buffers) 953638032Speter for macros defined in initsys() and settime(); since 953738032Speter these can have different values depending on which 953838032Speter envelope they are in. From Eric Wassenaar. 953938032Speter Improve logging to show ctladdr on to= logging; this tells you 954038032Speter what uid/gid processes ran as. 954138032Speter Fix a problem that caused error messages to be discarded if 954238032Speter the sender address was unparseable for some reason; 954338032Speter this was supposed to fall back to the "return to 954438032Speter postmaster" case. 954538032Speter Improve aliaswait backoff algorithm. 954638032Speter Portability patches for Linux (8.6.3 required another header 954738032Speter file) (from Karl London) and SCO UNIX. 954838032Speter CONFIG: patch prog mailer to not strip host name off of envelope 954938032Speter addresses (so that it matches local again). From 955038032Speter Christopher Davis. 955138032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 955238032Speter this prevents uux from seeing lines with null names like 955338032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 955438032Speter Nakamura of Kyoto University. 955538032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 955638032Speter it shouldn't fail miserably. From Motonori Nakamura. 955738032Speter 955864562Sgshapiro8.6.2/8.6.2 1993/10/15 955938032Speter Put a "successful delivery" message in the transcript for 956038032Speter addresses that get return-receipts. 956138032Speter Put a prominent "this is only a warning" message in warning 956238032Speter messages -- some people don't read carefully enough 956338032Speter and end up sending the message several times. 956438032Speter Include reason for temporary failure in the "warning" return 956538032Speter message. Currently, it just says "cannot send for 956638032Speter four hours". 956738032Speter Fix the "Original message received" time generated for 956838032Speter returntosender messages. It was previously listed as 956938032Speter the current time. Bug reported by Eric Hagberg of 957038032Speter Cornell University Medical College. 957138032Speter If there is an error when writing the body of a message, 957238032Speter don't send the trailing dot and wait for a response 957338032Speter in sender SMTP, as this could cause the connection to 957438032Speter hang up under some bizarre circumstances. From Eric 957538032Speter Wassenaar. 957638032Speter Fix some server SMTP synchronization problems caused when 957738032Speter connections fail during message collection. From 957838032Speter Eric Wassenaar. 957938032Speter Fix a problem that can cause srvrsmtp to reject mail if the 958038032Speter name server is down -- it accepts the RCPT but rejects 958138032Speter the DATA command. Problem reported by Jim Murray of 958238032Speter Stratus. 958338032Speter Fix a problem that can cause core dumps if the config file 958438032Speter incorrectly resolves to a null hostname. Reported by 958538032Speter Allan Johannesen of WPI. 958638032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 958738032Speter by non-root users were not put into 958838032Speter X-Authentication-Warning:s as intended because the 958943730Speter config file hadn't set the PrivacyOptions yet. Fix 959038032Speter from Sven-Ove Westberg of the University of Lulea. 959138032Speter Under very odd circumstances, the alias file rebuild code 959238032Speter could get confused as to whether a database was 959338032Speter open or not. 959438032Speter Check "vendor code" on the end of V lines -- this is 959538032Speter intended to provide a hook for vendor-specific 959638032Speter configuration syntax. (This is a "new feature", 959738032Speter but I've made an exception to my rule in a belief 959838032Speter that this is a highly exceptional case.) 959938032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 960038032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 960138032Speter (from Jon Forrest of UC Berkeley) 960238032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 960338032Speter 960464562Sgshapiro8.6.1/8.6 1993/10/08 960538032Speter Portability fixes for A/UX and Encore UMAX V. 960638032Speter Fix error message handling -- if you had a name server down 960738032Speter causing an error during parsing, that message was never 960838032Speter propagated to the queue file. 960938032Speter 961064562Sgshapiro8.6/8.6 1993/10/05 961138032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 961238032Speter conf.h (other systems have the same bug). 961338032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 961438032Speter getdtablesize() instead of sysconf(); a disturbingly 961538032Speter large number of systems defined _SC_OPEN_MAX in the 961638032Speter header files but don't have the syscall. 961738032Speter Another patch to really truly ignore MX records in getcanonname 961838032Speter if trymx == FALSE. 961938032Speter Fix problem that caused the "250 IAA25499 Message accepted for 962038032Speter delivery" message to be omitted if there was an error 962138032Speter in the header of the message (e.g., a bad Errors-To: 962238032Speter line). Pointed out by Michael Corrigan of UCSD. 962338032Speter Announce name of host we are chatting when we get errors; this 962438032Speter is an IDA-ism suggested by Christophe Wolfhugel. 962538032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 962638032Speter Australian Artificial Intelligence Institute), SCO Unix 962738032Speter (from Murray Kucherawy of Hookup Communication Corp.), 962838032Speter NeXT (from Vince DeMarco and myself), Linux (from 962938032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 963038032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 963138032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 963238032Speter Some changes to get around gcc optimizer bugs. From Takahiro 963338032Speter Kanbe. 963438032Speter Fix error recovery in queueup if another tf file of the same 963538032Speter name already exists. Problem stumbled over by Bill 963638032Speter Wisner of The Well. 963738032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 963838032Speter Problem noted by Keith McMillan of Ameritech Services. 963938032Speter Deal with group permissions properly when opening .forward and 964038032Speter :include: files. This relaxes the 8.1C restrictions 964138032Speter slightly more. This includes proper setting of groups 964238032Speter when reading :include: files, allowing you to read some 964338032Speter files that you should be able to read but have previously 964438032Speter been denied unless you owned them or they had "other" 964538032Speter read permission. 964638032Speter Make certain that $j is in $=w (after the .cf is read) so that 964738032Speter if the user is forced to override some silly system, 964838032Speter MX suppression will still work. 964938032Speter Fix a couple of efficiency problems where newstr was double- 965038032Speter calling expensive routines. In at least one case, it 965138032Speter wasn't guaranteed that they would always return the 965238032Speter same result. Problem noted by Christophe Wolfhugel. 965338032Speter Fix null pointer dereference in putoutmsg -- only on an error 965438032Speter condition from a non-SMTP mailer. From Motonori 965538032Speter Nakamura. 965638032Speter Macro expand "C" line class definitions before scanning so that 965738032Speter "CX $Z" works. 965838032Speter Fix problem that caused error message to be sent while still 965938032Speter trying to send the original message if the connection 966038032Speter is closed during a DATA command after getting an error 966138032Speter on an RCPT command (pretty obscure). Problem reported 966238032Speter by John Myers of CMU. 966338032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 966438032Speter term bug. 966538032Speter Fix a nasty bug causing core dumps when returning the "warning: 966638032Speter cannot deliver for N hours -- will keep trying" message; 966743730Speter it only occurred if you had PostmasterCopy set and 966838032Speter only on some architectures. Although sendmail would 966938032Speter keep trying, it would send error messages on each 967038032Speter queue interval. This is an important fix. 967138032Speter Allow u and g options to take user and group names respectively. 967238032Speter Don't do a chdir into the queue directory in -bt mode to make 967338032Speter ruleset testing a bit easier. 967438032Speter Don't allow users to turn off logging (using -oL) on the command 967538032Speter line -- command line can only raise, not lower, logging 967638032Speter level. 967738032Speter Set $u to the original recipient on the SMTP transaction or on 967838032Speter the command line. This is only done if there is exactly 967938032Speter one recipient. Technically, this does not meet the 968038032Speter specs, because it does not guarantee a domain on the 968138032Speter address. 968238032Speter Fix a problem that dumped error messages on bad addresses if 968338032Speter you used the -t flag. Problem noted by Josh Smith of 968438032Speter Harvey Mudd College. 968538032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 968638032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 968738032Speter avoid the problem of people who use angle brackets in 968838032Speter their full name information. 968938032Speter Fix a null pointer dereference if you set option "l", have 969038032Speter an Errors-To: header in the message, and have Errors-To: 969138032Speter defined in the config file H lines. From J.R. Oldroyd. 969238032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 969338032Speter wrong when compiling. Suggested by Rick McCarty of TI. 969438032Speter Fix a problem that could pass negative SIZE parameter if the 969538032Speter df file got lost; this would cause servers to always 969638032Speter give a temporary failure, making the problem even worse. 969738032Speter Problem noted by Allan Johannesen of WPI. 969838032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 969938032Speter protocol timeouts (30s default). Requested by Murray 970038032Speter Kucherawy of HookUp Communication Corp. to handle bogus 970138032Speter PC TCP/IP implementations. 970238032Speter Change $w default definition to be just the first component of 970338032Speter the domain name on config level 5. The $j macro defaults 970438032Speter to the FQDN; $m remains as before. This lets well-behaved 970538032Speter config files use any of the short, long, or subdomain 970638032Speter names. 970738032Speter Add makesendmail script in src to try to automate multi-architecture 970838032Speter builds. I know, this is sub-optimal, but it is still 970938032Speter helpful. 971038032Speter Fix very obscure race condition that can cause a queue run to 971138032Speter get a queue file for an already completed job. This 971238032Speter problem has existed for years. Problem noted by the 971338032Speter long suffering Allan Johannesen of WPI. 971438032Speter Fix a problem that caused the raw sender name to be passed to 971538032Speter udbsender instead of the canonified name -- this caused 971638032Speter it to sometimes miss records that it should have found. 971738032Speter Relax check of name on HELO packet so that a program using -bs 971838032Speter that claims to be itself works properly. 971938032Speter Restore rewriting of $: part of address through 2, R, 4 in 972038032Speter buildaddr -- this requires passing a lot of flags to get 972138032Speter it right. Unlike old versions, this ONLY rewrites 972238032Speter recipient addresses, not sender addresses. 972338032Speter Fix a bug that caused core dumps in config files that cannot 972438032Speter resolve /file/name style addresses. Fix from Jonathan 972538032Speter Kamens of OpenVision Technologies. 972638032Speter Fix problem with fcntl locking that can cause error returns to 972738032Speter be lost if the lock is lost; this required fully 972838032Speter queueing everything, dropping the envelope (so errors 972938032Speter would get returned), and then re-reading the queue from 973038032Speter scratch. 973138032Speter Fix a problem that caused aliases that redefine an otherwise 973238032Speter true address to still send to the original address 973338032Speter if and only if the alias failed in certain bizarre 973438032Speter ways (e.g, if they pointed at a list:; syntax address). 973538032Speter Problem pointed out by Jonathan Kamens. 973638032Speter Remove support for frozen configuration files. They caused 973738032Speter more trouble than it was worth. 973838032Speter Fix problem that can cause error messages to get ignored when 973938032Speter using both -odb and -t flags. Problem noted by Rob 974038032Speter McNicholas at U.C. Berkeley. 974138032Speter Include all "normal" variations on hostname in $=w. For example, 974238032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 974338032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 974438032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 974538032Speter the queue. 974638032Speter Reset SmtpPhase global on initial connection creation so that 974738032Speter messages don't come out with stale information. 974838032Speter Pass an "ext" argument to lockfile so that error/log messages 974938032Speter will properly reflect the true filename being locked. 975038032Speter Put all [...] address forms into $=w -- this eliminates the need 975138032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 975238032Speter Myers of CMU. 975338032Speter Fix a bug that can cause qf files to be left around even after 975438032Speter an SMTP RSET command. Problem and fix from Michael 975538032Speter Corrigan. 975643730Speter Don't send a PostmasterCopy to errors when the Precedence: is 975738032Speter negative. Error reports still go to the envelope 975838032Speter sender address. 975938032Speter Add LA_SHORT for load averages. 976038032Speter Lock sendmail.st file when posting statistics. 976138032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 976238032Speter set the size of the TCP send and receive buffers; if you 976338032Speter run over a slow slip line you may need to set these down 976438032Speter (although it would be better to fix the SLIP implementation 976538032Speter so that it's not necessary to recompile every program 976638032Speter that does bulk data transfer). 976738032Speter Allow null defaults on $( ... $) lookups. Problem reported by 976838032Speter Amir Plivatsky. 976938032Speter Diagnose crufty S and V config lines. This resulted from an 977038032Speter observation that some people were using the SITE macro 977138032Speter without the SITECONFIG macro first, which was causing 977238032Speter bogus config files that were not caught. 977338032Speter Fix makemap -f flag to turn off case folding (it was turning it 977438032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 977538032Speter Fix a problem that caused multiple error messages to be sent if 977638032Speter you used "sendmail -t -oem -odb", your system uses fcntl 977738032Speter locking, and one of the recipient addresses is unknown. 977838032Speter Reset uid earlier in include() so that recursive .forwards or 977938032Speter :include:s don't use the wrong uid. 978038032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 978138032Speter called, the code to recover the descriptor was broken. 978238032Speter This sometimes (only sometimes) caused problems with the 978338032Speter alias file. Fix from Motonori Nakamura. 978438032Speter Fix a problem that caused aliaswait to go into infinite recursion 978538032Speter if the @:@ metasymbol wasn't found in the alias file. 978638032Speter Improve error message on newaliases if database files cannot be 978738032Speter opened or if running with no database format defined. 978838032Speter Do a better estimation of the size of error messages when NoReturn 978938032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 979038032Speter Fix a problem causing the "c" option (don't connect to expensive 979138032Speter mailers) to be ignored in SMTP. Problem noted and the 979238032Speter solution suggested by Robert Elz of The University of 979338032Speter Melbourne. 979438032Speter Improve connection caching algorithm by passing "[host]" to 979538032Speter hostsignature, which strips the square brackets and 979638032Speter returns the real name. This allows mailertable entries 979738032Speter to match regular entries. 979838032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 979938032Speter feature, even if it doesn't work right. 980038032Speter Catch and log attempts to try the "wiz" command in server SMTP. 980138032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 980238032Speter Be more generous at assigning $z to the home directory -- do this 980338032Speter for programs that are specified through a .forward file. 980438032Speter Fix from Andrew Chang of Sun Microsystems. 980538032Speter Always save a fatal error message in preference to a non-fatal 980638032Speter error message so that the "subject" line of return 980738032Speter messages is the best possible. 980838032Speter CONFIG: reduce the number of quotes needed to quote configuration 980938032Speter parameters with commas: two quotes should work now, e.g., 981038032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 981138032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 981238032Speter connections (domain-ized UUCP). 981338032Speter CONFIG: fix bug in default maps (-o must be before database file 981464562Sgshapiro name). Pointed out by Christophe Wolfhugel. 981538032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 981638032Speter DNS. This would presumably be used in UUCP islands. 981738032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 981838032Speter CONFIG: log $u in Received: line. This is in technical violation 981938032Speter of the standards, since it doesn't guarantee a domain 982038032Speter on the address. 982138032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 982238032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 982338032Speter the "m" flag should you want it. Apparently some Solaris 2.2 982438032Speter installations can't handle multiple local recipients. 982538032Speter Problem noted by Josh Smith. 982638032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 982738032Speter CONFIG: change default version level from 4 to 5. 982838032Speter CONFIG: add FEATURE(nullclient) to create a config file that 982938032Speter forwards all mail to a hub without ever looking at the 983038032Speter addresses in any detail. 983138032Speter CONFIG: properly strip mailer: information off of relays when 983238032Speter used to change .BITNET form into %-hack form. 983338032Speter CONFIG: fix a problem that caused infinite loops if presented 983438032Speter with an address such as "!foo". 983538032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 983638032Speter the reverse "PTR" mapping is broken. There's a better 983738032Speter way to do this, but the change is fairly major and I 983838032Speter want to hold it for another release. Problem noted by 983938032Speter Bret Marquis. 984038032Speter 984164562Sgshapiro8.5/8.5 1993/07/23 984238032Speter Serious bug: if you used a command line recipient that was unknown 984338032Speter sendmail would not send a return message (it was treating 984438032Speter everything as though it had an SMTP-style client that 984538032Speter would do the return itself). Problem noted by Josh Smith. 984638032Speter Change "trymx" option in getcanonname() to ignore all MX data, 984738032Speter even during a T_ANY query. This actually didn't break 984838032Speter anything, because the only time you called getcanonname 984938032Speter with !trymx was if you already knew there were no MX 985038032Speter records, but it is somewhat cleaner. From Motonori 985138032Speter Nakamura. 985238032Speter Don't call getcanonname from getmxrr if you already know there 985338032Speter are no DNS records matching the name. 985438032Speter Fix a problem causing error messages to always include "The 985538032Speter original message was received ... from localhost". 985638032Speter The correct original host information is now included. 985738032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 985838032Speter version of "test" doesn't have the -x flag). Change it 985938032Speter to use -f instead. From John Myers. 986038032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 986138032Speter esmtp -- it should be smtp. 986238032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 986338032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 986438032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 986538032Speter this cleans up the configs somewhat. This fixes a serious 986638032Speter problem that caused route-addrs to get mistaken as relays, 986738032Speter pointed out by John Myers. WARNING: this also causes 986838032Speter the default on SMART_HOST to change from "suucp" to 986938032Speter "relay" if you have MAILER(smtp) specified. 987038032Speter 987164562Sgshapiro8.4/8.4 1993/07/22 987238032Speter Add option `w'. If you receive a message that comes to you because 987338032Speter you are the best (lowest preference) target of an MX, and 987438032Speter you haven't explicitly recognized the source MX host in 987538032Speter your .cf file, this option will cause you to try the target 987638032Speter host directly (as if there were no MX for it at all). If 987738032Speter `w' is not set, this case is a configuration error. 987838032Speter Beware: if `w' is set, senders may get bogus errors like 987938032Speter "message timed out" or "host unknown" for problems that 988038032Speter are really configuration errors. This option is 988138032Speter disrecommended, provided only for compatibility with 988238032Speter UIUC sendmail. 988338032Speter Fix a problem that caused the incoming socket to be left open 988438032Speter when sendmail forks after the DATA command. This caused 988538032Speter calling systems to wait in FIN_WAIT_2 state until the 988638032Speter entire list was processed and the child closed -- a 988738032Speter potentially prodigious amount of time. Problem noted 988838032Speter by Neil Rickert. 988938032Speter Fix problem (created in 6.64) that caused mail sent to multiple 989038032Speter addresses, one of which was a bad address, to completely 989138032Speter suppress the sending of the message. This changes 989238032Speter handling of EF_FATALERRS somewhat, and adds an 989338032Speter EF_GLOBALERRS flag. This also fixes a potential problem 989438032Speter with duplicate error messages if there is a syntax error 989538032Speter in the header of a message that isn't noticed until late 989638032Speter in processing. Original problem pointed out by Josh Smith 989738032Speter of Harvey Mudd College. This release includes quite a bit 989838032Speter of dickering with error handling (see below). 989938032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 990038032Speter will only hurt already-broken software and should help 990138032Speter humans. 990238032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 990338032Speter compiled in. It would never read the alias file. 990438032Speter Repair unbalanced `)' and `>' (the "open" versions are already 990538032Speter repaired). 990638032Speter Logging of "done" in dropenvelope() was incorrect: it would 990738032Speter log this even when the queue file still existed. Change 990838032Speter this to only log "done" (at log level 11) when the 990938032Speter queue file is actually removed. From John Myers. 991038032Speter Log "lost connection" in server SMTP at log level 20 if there 991138032Speter is no pending transaction. Some senders just close the 991238032Speter connection rather than sending QUIT. 991338032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 991438032Speter domains that do not have MX records -- this would cause 991538032Speter the subsequent host name lookup to fail. The problem 991638032Speter only occurred if you had FEATURE(nocanonify) set. 991738032Speter Problem noted by Rick McCarty of Texas Instruments. 991838032Speter Fix invocation of setvbuf when passed a -X flag -- I had 991938032Speter unwittingly used an ANSI C extension, and this caused 992038032Speter core dumps on some machines. 992138032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 992238032Speter Previously it just gave an empty send queue, which 992338032Speter then gave either "Need RCPT (recipient)" at the DATA 992438032Speter (confusing, since you had given an RCPT command which 992538032Speter returned 250) or just dropped the email, depending on 992638032Speter whether you were running VERBose mode. Now it usually 992738032Speter diagnoses this case as "aliasing/forwarding loop broken". 992838032Speter Unfortunately, it still doesn't adequately diagnose 992938032Speter some true error conditions. 993038032Speter Add internal concept of "warning messages" using 6xx codes. 993138032Speter These are not reported only to Postmaster. Unbalanced 993238032Speter parens, brackets, and quotes are printed as 653 codes. 993338032Speter They are always mapped to 5xx codes before use in SMTP. 993438032Speter Clean up error messages to tell both the actual address that 993538032Speter failed and the alias they arose from. This makes it 993638032Speter somewhat easier to diagnose problems. Difficulty noted 993738032Speter by Motonori Nakamura. 993838032Speter Fix a problem that inappropriately added a ctladdr to addresses 993938032Speter that shouldn't have had one during a queue run. This 994038032Speter caused error messages to be handled differently during 994138032Speter a queue run than a direct run. 994238032Speter Don't print the qf name and line number if you get errors during 994338032Speter the direct run of the queue from srvrsmtp -- this was 994438032Speter just extra stuff for users to crawl through. 994538032Speter Put command line flags on second line of pid file so you can 994638032Speter auto-restart the daemon with all appropriate arguments. 994738032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 994838032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 994938032Speter restart it. 995038032Speter Remove the ``setuid(getuid())'' in main -- this caused the 995138032Speter IDENT daemon to screw up. This required that I change 995238032Speter HASSETEUID to HASSETREUID and complicate the mode 995338032Speter changing somewhat because both Ultrix and SunOS seem 995438032Speter to have a bug causing seteuid() to set the saved uid 995538032Speter as well as the effective. The program test/t_setreuid.c 995638032Speter will test to see if your implementation of setreuid(2) 995738032Speter is appropriately functional. 995838032Speter The FallBackMX (option V) handling failed to properly identify 995938032Speter fallback to yourself -- most of the code was there, 996038032Speter but it wasn't being enabled. Problem noted by Murray 996138032Speter Kucherawy of the University of Waterloo. 996238032Speter Change :include: open timeout from ETIMEDOUT to an internal 996338032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 996438032Speter with CurHostName" in error messages, which can be 996538032Speter confusing. Reported by Jonathan Kamens of OpenVision 996638032Speter Technologies. 996738032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 996838032Speter process group id. The original fix was to get around 996938032Speter some problems with recalcitrant MUAs, but it breaks 997038032Speter any call from a shell that creates a process group id 997138032Speter different from the process id. I could try to fix 997238032Speter this by diddling the tty owner (using tcsetpgrp or 997338032Speter equivalent) but this is too likely to break other 997438032Speter things. 997538032Speter Portability changes: 997638032Speter Support -M as equivalent to -oM on Ultrix -- apparently 997738032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 997838032Speter instead of using standard flags. Oh joy. This 997943730Speter behavior reported by Jon Giltner of University 998038032Speter of Colorado. 998138032Speter SGI IRIX -- this includes several changes that should 998238032Speter help other strict ANSI compilers. 998338032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 998438032Speter Corporation. 998538032Speter Solaris running the Sun C compiler (which despite the 998638032Speter documentation apparently doesn't define 998738032Speter __STDC__ by default). 998838032Speter ConvexOS from Eric Schnoebelen of Convex. 998938032Speter Sony NEWS workstations and Omron LUNA workstations from 999038032Speter Motonori Nakamura. 999138032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 999238032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 999338032Speter several people have made a good argument that this 999438032Speter creates more problems than it solves (although this 999538032Speter may prove painful in the short run). 999638032Speter CONFIG: generalize all the relays to accept a "mailer:host" 999738032Speter format. 999838032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 999938032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1000038032Speter addresses are also passed through this ruleset. 1000138032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1000238032Speter internet-style addresses would "fall off the end" of 1000338032Speter ruleset zero and be interpreted as local -- however, 1000438032Speter the angle brackets confused the recursive call. 1000538032Speter These are now diagnosed as "Unrecognized host name". 1000638032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1000738032Speter ifdef(`_MAILER_USENET_') instead of 1000838032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1000938032Speter of SINTEF RUNIT, Oslo. 1001038032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1001138032Speter early in ruleset 0; this allows .mc authors to bypass 1001238032Speter things like the "short circuit" code for local addresses. 1001338032Speter Prompted by a comment by Bill Wisner of The Well. 1001438032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1001538032Speter esmtp) to send SMTP mail. This allows you to default 1001638032Speter to esmtp but use a mailertable or other override to 1001738032Speter deal with broken servers. This logic was pointed out 1001838032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1001938032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1002038032Speter environments. Ugly as sin. 1002138032Speter 1002264562Sgshapiro8.3/8.3 1993/07/13 1002338032Speter Fix setuid problems introduced in 8.2 that caused messages 1002438032Speter like "Cannot create qfXXXXXX: Invalid argument" 1002538032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1002638032Speter involved a new compile flag "HASSETEUID" that takes 1002738032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1002838032Speter that the POSIX interface is broken enough to break 1002938032Speter some systems badly. This includes some fixes for 1003038032Speter HP-UX. Also fixes problems where the real uid is 1003138032Speter not reset properly on startup (from Neil Rickert). 1003238032Speter Fix a problem that caused timed out messages to not report the 1003338032Speter addresses that timed out. Error messages are also more 1003438032Speter "user friendly". 1003538032Speter Drop required bandwidth on connections from 64 bytes/sec to 1003638032Speter 16 bytes/sec. 1003738032Speter Further Solaris portability changes -- doesn't require the BSD 1003838032Speter compatibility library. This also adds a new 1003938032Speter "HASGETDTABLESIZE" compile flag which can be used if 1004038032Speter you want to use getdtablesize(2) instead of sysconf(2). 1004138032Speter These are loosely based on changes from David Meyer at 1004238032Speter University of Oregon. This now seems to work, at least 1004338032Speter for quick test cases. 1004438032Speter Fix a problem that can cause duplicate error messages to be 1004538032Speter sent if you are in SMTP, you send to multiple addresses, 1004638032Speter and at least one of those addresses is good and points 1004738032Speter to an account that has a .forward file (whew!). 1004838032Speter Fix a problem causing messages to be discarded if checkcompat() 1004938032Speter returned EX_TEMPFAIL (because it didn't properly mark 1005038032Speter the "to" address). Problem noted by John Myers. 1005138032Speter Fix dfopen to return NULL if the open failed; I was depending 1005238032Speter on fdopen(-1) returning NULL, which isn't the case. This 1005338032Speter isn't serious, but does result in weird error diagnoses. 1005438032Speter From Michael Corrigan. 1005538032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1005638032Speter messages sent through UUCP-family mailers. Suggested 1005738032Speter by Bill Wisner of The Well. 1005838032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1005938032Speter include a "uucp-dom" mailer that uses domain-style 1006038032Speter addressing. Suggested by Bill Wisner. 1006138032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1006238032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1006338032Speter Christophe Wolfhugel. 1006438032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1006538032Speter 1006664562Sgshapiro8.2/8.2 1993/07/11 1006738032Speter Don't drop out on config file parse errors in -bt mode. 1006838032Speter On older configuration files, assume option "l" (use Errors-To 1006938032Speter header) for back compatibility. NOTE: this DOES NOT 1007038032Speter imply an endorsement of the Errors-To: header in any way. 1007138032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1007238032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1007338032Speter SMTP server to give an error on this command, and 1007438032Speter logging it in the transcript can be confusing. Fix 1007538032Speter from Bill Wisner. 1007638032Speter IRIX compatibility changes provided by Dan Rich 1007738032Speter <drich@sandman.lerc.nasa.gov>. 1007838032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1007938032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1008038032Speter <juo@klinzhai.rutgers.edu> 1008138032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1008238032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1008338032Speter match the other flags in that file. 1008438032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1008538032Speter Save h_errno in mci struct and improve error message display. 1008638032Speter Changes from Eric Wassenaar. 1008738032Speter Open /dev/null for the transcript if the create of the xf file 1008838032Speter failed; this avoids at least one possible null pointer 1008938032Speter reference in very weird cases. From Eric Wassenaar. 1009038032Speter Clean up statistics gathering; it was over-reporting because of 1009138032Speter forks. From Eric Wassenaar. 1009238032Speter Fix problem that causes old Return-Path: line to override new 1009338032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1009438032Speter re-using old value). From Motonori Nakamura. 1009538032Speter Fix broken -m flag in K definition -- even if -m (match only) 1009638032Speter was specified, it would still replace the key with the 1009738032Speter value. Noted by Rick McCarty of Texas Instruments. 1009838032Speter If the name server timed out over several days, no "timed out" 1009938032Speter message would ever be sent back. The timeout code 1010038032Speter has been moved from markfailure() to dropenvelope() 1010138032Speter so that all such failures should be diagnosed. Pointed 1010238032Speter out by Christophe Wolfhugel and others. 1010338032Speter Relax safefile() constraints: directories in an include or 1010438032Speter forward path must be readable by self if the controlling 1010538032Speter user owns the entry, readable by all otherwise (e.g., 1010638032Speter when reading your .forward file, you have to own and 1010738032Speter have X permission in it; everyone needs X permission in 1010838032Speter the root and directories leading up to your home); 1010938032Speter include files must be readable by anyone, but need not 1011038032Speter be owned by you. 1011138032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1011238032Speter reading a .forward file; this gets around some problems 1011338032Speter on NFS mounts if root permission is not exported and 1011438032Speter the user's home directory isn't x'able. 1011538032Speter Additional NeXT portability enhancements from Axel Zinser. 1011638032Speter Additional HP-UX portability enhancements from Brian Bullen. 1011738032Speter Add a timeout around SMTP message writes; this assumes you can 1011838032Speter get throughput of at least 64 bytes/second. Note that 1011938032Speter this does not impact the "datafinal" default, which 1012038032Speter is separate; this is just intended to work around 1012138032Speter network clogs that will occur before the final dot 1012238032Speter is sent. From Eric Wassenaar. 1012338032Speter Change map code to set the "include null" flag adaptively -- 1012438032Speter it initially tries both, but if it finds anything 1012538032Speter matching without a null it never tries again with a 1012638032Speter null and vice versa. If -N is specified, it never 1012738032Speter tries without the null and creates new maps with a 1012838032Speter null byte. If -O is specified, it never tries with 1012938032Speter the null (for efficiency). If -N and -O are specified, 1013038032Speter you get -NO (get it?) lookup at all, so this would 1013138032Speter be a bad idea. If you don't specify either -N or -O, 1013238032Speter it adapts. 1013338032Speter Fix recognition of "same from address" so that MH submissions 1013438032Speter will insert the appropriate full name information; 1013538032Speter this used to work and got broken somewhere along the 1013638032Speter way. 1013738032Speter Some changes to eliminate some unnecessary SYSERRs in the 1013838032Speter log. For example, if you lost a connection, don't 1013938032Speter bother reporting that fact on the connection you lost. 1014038032Speter Add some "extended debugging" flags to try to track down 1014138032Speter why we get occasional problems with file descriptor 1014238032Speter one being closed when execing a mailer; it seems to 1014338032Speter only happen when there has been another error in the 1014438032Speter same transaction. This requires XDEBUG, defined 1014538032Speter by default in conf.h. 1014638032Speter Add "-X filename" command line flag, which logs both sides of 1014738032Speter all SMTP transactions. This is intended ONLY for 1014838032Speter debugging bad implementations of other mailers; start 1014938032Speter it up, send a message from a mailer that is failing, 1015038032Speter and then kill it off and examine the indicated log. 1015138032Speter This output is not intended to be particularly human 1015238032Speter readable. This also adds the HASSETVBUF compile 1015338032Speter flag, defaulted on if your compiler defines __STDC__. 1015438032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1015538032Speter have a local net that should get direct connects, you 1015638032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1015738032Speter See cf/README for an example. 1015838032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1015938032Speter sites that don't use the -d flag. 1016038032Speter CONFIG: hide recipient addresses as well as sender addresses 1016138032Speter behind $M if FEATURE(allmasquerade) is specified; this 1016238032Speter has been requested by several people, but can break 1016338032Speter local aliases. For example, if you mail to "localalias" 1016438032Speter this will be rewritten as "localalias@masqueradehost"; 1016538032Speter although initial delivery will work, replies will be 1016638032Speter broken. Use it sparingly. 1016738032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1016838032Speter to qualified domains in headers. I believe this is 1016938032Speter largely equivalent to the IDA feature of the same name. 1017038032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1017138032Speter to override the "system name" as your UUCP name -- 1017238032Speter in particular, to use domain-ized UUCP names. From 1017338032Speter Bill Wisner of The Well. 1017438032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1017538032Speter first. This is currently unused in the config files, 1017638032Speter but could be used in a mailertable entry. 1017738032Speter 1017864562Sgshapiro8.1C/8.1B 1993/06/27 1017938032Speter Serious security bug fix: it was possible to read any file on 1018038032Speter the system, regardless of ownership and permissions. 1018138032Speter If a subroutine returns a fully qualified address, return it 1018238032Speter immediately instead of feeding it back into rewriting. 1018338032Speter This fixes a problem with mailertable lookups. 1018438032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1018538032Speter 1018664562Sgshapiro8.1B/8.1A 1993/06/12 1018738032Speter Serious bug fix: pattern matching backup algorithm stepped by 1018838032Speter two tokens in classes instead of one. Found by Claus 1018938032Speter Assmann at University of Kiel, Germany. 1019038032Speter 1019164562Sgshapiro8.1A/8.1A 1993/06/08 1019238032Speter Another mailertable fix.... 1019338032Speter 1019464562Sgshapiro8.1/8.1 1993/06/07 1019538032Speter 4.4BSD freeze. No semantic changes. 10196
