138032Speter SENDMAIL RELEASE NOTES 2173340Sgshapiro $Id: RELEASE_NOTES,v 8.1909 2007/10/31 16:04:13 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 9173340Sgshapiro8.14.2/8.14.2 2007/11/01 10173340Sgshapiro If a message was queued and it contained 8 bit characters in 11173340Sgshapiro a From: or To: header, then those characters could be 12173340Sgshapiro "mistaken" for internal control characters during a queue 13173340Sgshapiro run and trigger various consistency checks. Problem 14173340Sgshapiro noted by Neil Rickert of Northern Illinois University. 15173340Sgshapiro If MaxMimeHeaderLength is set to a value greater than 0 (which 16173340Sgshapiro it is by default) then even if the Linelimit parameter 17173340Sgshapiro is 0, sendmail corrupted in the non-transfer-encoding 18173340Sgshapiro case every MAXLINE-1 characters. Patch from John Gardiner 19173340Sgshapiro Myers of Proofpoint. 20173340Sgshapiro Setting the suboption DeliveryMode for DaemonPortOptions did not 21173340Sgshapiro work in earlier 8.14 versions. 22173340Sgshapiro Note: DeliveryMode=interactive is silently converted to 23173340Sgshapiro background if a milter can reject or delete a recipient. 24173340Sgshapiro Prior to 8.14 this happened only if milter could delete 25173340Sgshapiro recipients. 26173340Sgshapiro ClientRate should trigger when the limit was exceeded (as 27173340Sgshapiro documented), not when it was reached. Patch from 28173340Sgshapiro John Beck of Sun Microsystems. 29173340Sgshapiro Force a queue run for -qGqueuegroup even if no runners are 30173340Sgshapiro specified (R=0) and forking (F=f) is requested. 31173340Sgshapiro When multiple results are requested for a DNS map lookup 32173340Sgshapiro (-z and -Z), return only those that are relevant for 33173340Sgshapiro the query (not also those in the "additional section".) 34173340Sgshapiro If the message transfer time to sendmail (when acting as server) 35173340Sgshapiro exceeds Timeout.queuewarn or Timeout.queuereturn and 36173340Sgshapiro the message is refused (by a milter), sendmail previously 37173340Sgshapiro created a delivery status notification (DSN). Patch 38173340Sgshapiro from Doug Heath of The Hertz Corporation. 39173340Sgshapiro A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires 40173340Sgshapiro the MTA to deal with some input (i.e., "=") itself. 41173340Sgshapiro Problem noted by Eliot Lear. 42173340Sgshapiro sendmail counted a delivery as successful if PIPELINING is 43173340Sgshapiro compiled in but not offered by the server and the 44173340Sgshapiro delivery failed temporarily. Patch from Werner Wiethege. 45173340Sgshapiro If getting the result of an LDAP query times out then close the 46173340Sgshapiro map so it will be reopened on the next lookup. This 47173340Sgshapiro should help "failover" configurations that specify more 48173340Sgshapiro than one LDAP server. 49173340Sgshapiro If check_compat returns $#discard then a "savemail panic" could 50173340Sgshapiro be triggered under some circumstances (e.g., requiring 51173340Sgshapiro a system which does not have the compile time flag 52173340Sgshapiro HASFLOCK set). Based on patch by Motonori Nakamura 53173340Sgshapiro of National Institute of Informatics, Japan. 54173340Sgshapiro If a milter rejected a recipient, the count for nrcpts= in the 55173340Sgshapiro logfile entry might have been wrong. Problem found by 56173340Sgshapiro Petra Humann of TU Dresden. 57173340Sgshapiro If a milter invoked smfi_chgfrom() where ESMTP arguments are not 58173340Sgshapiro NULL, the message body was lost. Patch from Motonori 59173340Sgshapiro Nakamura of National Institute of Informatics, Japan. 60173340Sgshapiro sendmail(8) had a bogus space in -qGname. Patch from Peng Haitao. 61173340Sgshapiro CONTRIB: buildvirtuser: Preserve ownership and permissions when 62173340Sgshapiro replacing files. 63173340Sgshapiro CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when 64173340Sgshapiro reading the /etc/mail/virtusers/ directory. 65173340Sgshapiro CONTRIB: buildvirtuser: Emit warnings instead of exiting where 66173340Sgshapiro appropriate. 67173340Sgshapiro LIBMILTER: Fix ABI backwards compatibility so milters compiled 68173340Sgshapiro against an older libmilter.so shared library can use an 69173340Sgshapiro 8.14 libmilter.so shared library. 70173340Sgshapiro LIBMILTER: smfi_version() did not properly extract the patchlevel 71173340Sgshapiro from the version number, however, the returned value was 72173340Sgshapiro correct for the current libmilter version. 73173340Sgshapiro 74168515Sgshapiro8.14.1/8.14.1 2007/04/03 75168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 76168515Sgshapiro it in its list of recipients and deliver to it if the 77168515Sgshapiro transaction is accepted. This is a regression introduced 78168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 79168515Sgshapiro found by Andy Fiddaman. 80168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 81168515Sgshapiro could not be set in 8.14.0. 82168515Sgshapiro If a server shut down the connection in response to a STARTTLS 83168515Sgshapiro command, sendmail would log a misleading error message 84168515Sgshapiro due to an internal inconsistency. Problem found by 85168515Sgshapiro Werner Wiethege. 86168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 87168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 88168515Sgshapiro Science and Mathematics. 89168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 90168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 91168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 92168515Sgshapiro m4 options for setting MaxNOOPCommands and 93168515Sgshapiro SharedMemoryKeyFile. 94168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 95168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 96168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 97168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 98168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 99168515Sgshapiro currently available macros. Problem found by Andy Fiddaman. 100168515Sgshapiro LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option 101168515Sgshapiro negotiation. Problem reported by Bryan Costales. 102168515Sgshapiro LIBMILTER: Fix several minor errors in the documentation. 103168515Sgshapiro Patches from Bryan Costales. 104168515Sgshapiro PORTABILITY FIXES: 105168515Sgshapiro AIX 5.{1,2}: libsm/util.c failed to compile due to 106168515Sgshapiro redefinition of several macros, e.g., SIG_ERR. 107168515Sgshapiro Patch from Jim Pirzyk with assistance by Bob 108168515Sgshapiro Booth, University of Illinois at Urbana-Champaign. 109168515Sgshapiro Add support for QNX.6. Patch from Sean Boudreau of QNX 110168515Sgshapiro Software Systems. 111168515Sgshapiro New Files: 112168515Sgshapiro devtools/M4/depend/QNX6.m4 113168515Sgshapiro devtools/OS/QNX.6.x 114168515Sgshapiro include/sm/os/sm_os_qnx.h 115168515Sgshapiro 116168515Sgshapiro New Files added in 8.14.0, but not shown in the release notes entry: 117168515Sgshapiro libmilter/docs/smfi_chgfrom.html 118168515Sgshapiro libmilter/docs/smfi_version.html 119168515Sgshapiro 120168515Sgshapiro8.14.0/8.14.0 2007/01/31 121168515Sgshapiro Header field values are now 8 bit clean. Notes: 122168515Sgshapiro - header field names are still restricted to 7 bit. 123168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 124168515Sgshapiro headers. 125168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 126168515Sgshapiro number of spaces after the colon would be changed to 127168515Sgshapiro exactly one space. 128168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 129168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 130168515Sgshapiro limit may be reached too early, e.g., the counter 131168515Sgshapiro may be off by a factor of 4 in case of a sequence of 132168515Sgshapiro .forward files that refer to others. Patch from 133168515Sgshapiro Motonori Nakamura of Kyoto University. 134168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 135168515Sgshapiro "sendmail -bs" can trigger an assertion because the 136168515Sgshapiro hostname of the client is undefined. It is now set 137168515Sgshapiro to "localhost" for the xxfi_connect() callback. 138168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 139168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 140168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 141168515Sgshapiro Patch from Nik Clayton. 142168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 143168515Sgshapiro permanent errors (5xy). This can be useful for testing. 144168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 145168515Sgshapiro per daemon socket: 146168515Sgshapiro DeliveryMode DeliveryMode 147168515Sgshapiro refuseLA RefuseLA 148168515Sgshapiro delayLA DelayLA 149168515Sgshapiro queueLA QueueLA 150168515Sgshapiro children MaxDaemonChildren 151168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 152168515Sgshapiro lookup key with the LDAP escaped contents of the 153168515Sgshapiro arguments specified in the map lookup. Loosely based 154168515Sgshapiro on patch from Wolfgang Hottgenroth. 155168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 156168515Sgshapiro from Nik Clayton. 157168515Sgshapiro If a client is rejected via TCP wrapper or some other check 158168515Sgshapiro performed by validate_connection() (in conf.c) then do 159168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 160168515Sgshapiro of the University of Illinois at Urbana-Champaign. 161168515Sgshapiro If a client terminates the SMTP connection during a pause 162168515Sgshapiro introduced by greet_pause, then a misleading message 163168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 164168515Sgshapiro et.al., patch from Matej Vela. 165168515Sgshapiro New command "mstat" for control socket to provide "machine 166168515Sgshapiro readable" status. 167168515Sgshapiro New named config file rule check_eom which is called at the end 168168515Sgshapiro of a message, its parameter is the size of the message. 169168515Sgshapiro If the macro {addr_type} indicates that the current address 170168515Sgshapiro is a header address it also distinguishes between 171168515Sgshapiro recipient and sender addresses (as it is done for 172168515Sgshapiro envelope addresses). 173168515Sgshapiro When a macro is set in check_relay, then its value is accessible 174168515Sgshapiro by all transactions in the same SMTP session. 175168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 176168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 177168515Sgshapiro number of "useless" commands before the SMTP server will 178168515Sgshapiro slow down responding. 179168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 180168515Sgshapiro enabled, the MTA can be asked to select a shared memory 181168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 182168515Sgshapiro a file where to store the selected key. 183168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 184168515Sgshapiro by recognizing some commands from them. If the first command 185168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 186168515Sgshapiro connection is terminated immediately. 187168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 188168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 189168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 190168515Sgshapiro New options B, z, and Z for DNS maps: 191168515Sgshapiro -B: specify a domain that is always appended to queries. 192168515Sgshapiro -z: specify the delimiter at which to cut off the result of 193168515Sgshapiro a query if it is too long. 194168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 195168515Sgshapiro to form the result of a lookup. 196168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 197168515Sgshapiro implicitly while building libsm, they must be explicitly 198168515Sgshapiro started by using "make check". 199168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 200168515Sgshapiro reported by the SATURN tool which has been developed by 201168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 202168515Sgshapiro Fix a potential race condition caused by a signal handler for 203168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 204168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 205168515Sgshapiro queue group selection. This has been disabled as it was not 206168515Sgshapiro intended. 207168515Sgshapiro New operator 'r' for the arith map to return a random number. 208168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 209168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 210168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 211168515Sgshapiro which may improve the communication performance on some 212168515Sgshapiro operating systems. Patch from John Gardiner Myers of 213168515Sgshapiro Proofpoint. 214168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 215168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 216168515Sgshapiro generate an additional blank line in the output as the last 217168515Sgshapiro line. 218168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 219168515Sgshapiro the "queue control process" (QCP) works now. 220168515Sgshapiro Increase the length of an input line to 12288 to deal with 221168515Sgshapiro really long lines during SMTP AUTH negotiations. 222168515Sgshapiro Problem noted by Werner Wiethege. 223168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 224168515Sgshapiro a missing initialization call for that case). Problem 225168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 226168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 227168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 228168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 229168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 230168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 231168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 232168515Sgshapiro the MTA will not attempt to open a statistics file on 233168515Sgshapiro each delivery. 234168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 235168515Sgshapiro clients whose IP address does not have proper reverse DNS. 236168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 237168515Sgshapiro and John Beck of Sun Microsystems. 238168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 239168515Sgshapiro clients which provide a HELO/EHLO argument which is either 240168515Sgshapiro unqualified, or is one of our own names (i.e., the server 241168515Sgshapiro name instead of the client name). Contributed by Neil 242168515Sgshapiro Rickert of Northern Illinois University and John Beck of 243168515Sgshapiro Sun Microsystems. 244168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 245168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 246168515Sgshapiro Based on contribution from William Dell Wisner. 247168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 248168515Sgshapiro the maximum line length of the smtp mailers. 249168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 250168515Sgshapiro to allow entries in the access map to be of the form 251168515Sgshapiro To:user@example.com RELAY 252168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 253168515Sgshapiro macros a milter should receive at those stages in the 254168515Sgshapiro SMTP dialogue. 255168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 256168515Sgshapiro for the HELO/EHLO command. 257168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 258168515Sgshapiro messages by using those values as second argument. 259168515Sgshapiro Patches from Nelson Fung. 260168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 261168515Sgshapiro ignores everything after it unless it is in quotes or 262168515Sgshapiro preceeded by a backslash. 263168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 264168515Sgshapiro directories, then it used for "make install" to create 265168515Sgshapiro the required installation directories. 266168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 267168515Sgshapiro executables (defaults to confCC). 268168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 269168515Sgshapiro has several changes which are listed below and documented 270168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 271168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 272168515Sgshapiro changed. It now refers only to the version of libmilter, 273168515Sgshapiro not to the protocol version (which is used only internally, 274168515Sgshapiro it is not user/milter-programmer visible). Additionally, 275168515Sgshapiro a version function smfi_version() has been introduced such 276168515Sgshapiro that a milter program can check the libmilter version also 277168515Sgshapiro at runtime which is useful if a shared library is used. 278168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 279168515Sgshapiro dynamically (i.e., at runtime) determine the available 280168515Sgshapiro protocol actions and features of the MTA and also to 281168515Sgshapiro specify which of these a milter wants to use. This allows 282168515Sgshapiro for more flexibility than hardcoding these flags in the 283168515Sgshapiro xxfi_flags field of the smfiDesc structure. 284168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 285168515Sgshapiro can act on the DATA command. 286168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 287168515Sgshapiro can receive also unknown SMTP commands. 288168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 289168515Sgshapiro can be used by the xxfi_header() callback provided the 290168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 291168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 292168515Sgshapiro xxfi_body() callback to skip over further body chunks 293168515Sgshapiro and directly advance to the xxfi_eom() callback. This 294168515Sgshapiro is useful if a milter can make a decision based on the 295168515Sgshapiro body chunks it already received without reading the entire 296168515Sgshapiro rest of the body and the milter wants to invoke functions 297168515Sgshapiro that are only available from the xxfi_eom() callback. 298168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 299168515Sgshapiro new recipients including ESMTP parameters. 300168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 301168515Sgshapiro envelope sender including ESMTP parameters. 302168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 303168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 304168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 305168515Sgshapiro a RCPT has been rejected can be checked by comparing the 306168515Sgshapiro value of the macro {rcpt_mailer} with "error". 307168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 308168515Sgshapiro wants to receive from the MTA for each protocol step 309168515Sgshapiro by invoking the function smfi_setsymlist() during option 310168515Sgshapiro negotiation. 311168515Sgshapiro LIBMILTER: A milter can receive header field values with all 312168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 313168515Sgshapiro protocol action. Also, if the flag is set then the MTA 314168515Sgshapiro does not add a leading space to headers that are added, 315168515Sgshapiro inserted, or replaced. 316168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 317168515Sgshapiro callback, the SMTP server will terminate the SMTP session 318168515Sgshapiro with that error to match the behavior of all other callbacks. 319168515Sgshapiro New Files: 320168515Sgshapiro cf/feature/badmx.m4 321168515Sgshapiro cf/feature/block_bad_helo.m4 322168515Sgshapiro cf/feature/require_rdns.m4 323168515Sgshapiro devtools/M4/UNIX/check.m4 324168515Sgshapiro include/sm/misc.h 325168515Sgshapiro include/sm/sendmail.h 326168515Sgshapiro include/sm/tailq.h 327168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 328168515Sgshapiro libmilter/docs/smfi_setsymlist.html 329168515Sgshapiro libmilter/docs/xxfi_data.html 330168515Sgshapiro libmilter/docs/xxfi_negotiate.html 331168515Sgshapiro libmilter/docs/xxfi_unknown.html 332168515Sgshapiro libmilter/example.c 333168515Sgshapiro libmilter/monitor.c 334168515Sgshapiro libmilter/worker.c 335168515Sgshapiro libsm/memstat.c 336168515Sgshapiro libsm/t-memstat.c 337168515Sgshapiro libsm/t-qic.c 338168515Sgshapiro libsm/util.c 339168515Sgshapiro sendmail/daemon.h 340168515Sgshapiro sendmail/map.h 341168515Sgshapiro 342161389Sgshapiro8.13.8/8.13.8 2006/08/09 343161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 344161389Sgshapiro the server can erroneously report that there is 345161389Sgshapiro insufficient disk space. Additionally make sure that 346161389Sgshapiro an internal variable is set properly to avoid those 347161389Sgshapiro misleading errors. Based on patch from Steve Hubert 348161389Sgshapiro of University of Washington. 349161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 350161389Sgshapiro the process that forks the daemon exited, i.e., if 351161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 352161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 353161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 354161389Sgshapiro David F.

However, 361161389Sgshapiro this did not match the documentation of the function, hence 362161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 363161389Sgshapiro about these macros. 364161389Sgshapiro 365159609Sgshapiro8.13.7/8.13.7 2006/06/14 366159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 367159609Sgshapiro crash while trying to send a mail due to a stack overflow, 368159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 369159609Sgshapiro happens because the recursion of the function mime8to7() 370159609Sgshapiro was not restricted. The function is called for MIME 8 to 371159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 372159609Sgshapiro To work around this problem, recursive calls are limited to 373159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 374159609Sgshapiro limit is treated as opaque and is not checked further. 375159609Sgshapiro Problem noted by Frank Sheiness. 376159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 377159609Sgshapiro SASL mechanisms that use the security layer, e.g., 378159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 379159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 380159609Sgshapiro a df file might have been left behind in the queue. 381159609Sgshapiro This was another side effect of the changes to the I/O 382159609Sgshapiro layer made in 8.13.6. 383159609Sgshapiro Several minor problems have been fixed that were found by a 384159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 385159609Sgshapiro distribution. See http://scan.coverity.com/ 386159609Sgshapiro Note: the scan generated also a lot of "false positives", 387159609Sgshapiro e.g., "error" reports about situations that cannot happen. 388159609Sgshapiro Most of those code places are marked with lint(1) comments 389159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 390159609Sgshapiro Hence an explicit assertion has been added in some cases 391159609Sgshapiro to avoid those false positives. 392159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 393159609Sgshapiro error then in some cases shared memory segments or pid 394159609Sgshapiro files were not removed. 395159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 396159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 397159609Sgshapiro reported by Akihiro Sagawa. 398159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 399159609Sgshapiro bug work-around. Hence if sendmail is linked against 400159609Sgshapiro either of these versions and compression is available, 401159609Sgshapiro the padding bug work-around is turned off.

Also fix handling of 416157001Sgshapiro a buffer in sm_syslog() which could have been used as an 417157001Sgshapiro attack vector to exploit the unsafe handling of 418157001Sgshapiro setjmp(3)/longjmp(3) in combination with signals. 419157001Sgshapiro Problem detected by Mark Dowd of ISS X-Force. 420157001Sgshapiro Handle theoretical integer overflows that could triggered if 421157001Sgshapiro the server accepted headers larger than the maximum 422157001Sgshapiro (signed) integer value. This is prevented in the default 423157001Sgshapiro configuration by restricting the size of a header, and on 424157001Sgshapiro most machines memory allocations would fail before reaching 425157001Sgshapiro those values. Problems found by Phil Brass of ISS. 426157001Sgshapiro If a server returns 421 for an RSET command when trying to start 427157001Sgshapiro another transaction in a session while sending mail, do 428157001Sgshapiro not trigger an internal consistency check. Problem found 429157001Sgshapiro by Allan E Johannesen of Worcester Polytechnic Institute. 430157001Sgshapiro If a server returns a 5xy error code (other than 501) in response 431157001Sgshapiro to a STARTTLS command despite the fact that it advertised 432157001Sgshapiro STARTTLS and that the code is not valid according to RFC 433157001Sgshapiro 2487 treat it nevertheless as a permanent failure instead 434157001Sgshapiro of a protocol error (which has been changed to a 435157001Sgshapiro temporary error in 8.13.5).

From John Beck of Sun Microsystems. 647132943Sgshapiro Fix SuperSafe=PostMilter behavior when a milter replaces a body 648132943Sgshapiro but the data file is not yet stored on disk because it is 649132943Sgshapiro smaller than the size of the memory buffer. Problem noted 650132943Sgshapiro by David Russell. 651132943Sgshapiro Fix certificate revocation list support; if a CRL was specified 652132943Sgshapiro but the other side presented a cert that was signed by 653132943Sgshapiro a different (trusted) CA than the one which issued the CRL, 654132943Sgshapiro verification would always fail. Problem noted by Al Smith. 655132943Sgshapiro Run mailer programs as the RunAsUser when RunAsUser is set and 656132943Sgshapiro the F=S mailer flag is set without a U= mailer equate. 657132943Sgshapiro Problem noted by John Gardiner Myers of Proofpoint. 658132943Sgshapiro ${nbadrcpts} was off by one if BadRcptThrottle is zero. 659132943Sgshapiro Patch from Sung-hoon Choi of DreamWiz Inc. 660132943Sgshapiro CONFIG: Emit a warning if FEATURE(`access_db') is used after 661132943Sgshapiro FEATURE(`greet_pause') because then the latter will not 662132943Sgshapiro use the access map. Note: if no default value is given 663132943Sgshapiro for FEATURE(`greet_pause') then it issues an error if 664132943Sgshapiro FEATURE(`access_db') is not specified before it. 665132943Sgshapiro Problem noted by Alexander Dalloz of University of 666132943Sgshapiro Bielefeld. 667132943Sgshapiro CONFIG: Invoke ruleset Local_greet_pause if FEATURE(`greet_pause') 668132943Sgshapiro is used to give more flexibility for local changes. 669132943Sgshapiro Portability: 670132943Sgshapiro Fix a 64 bit problem in the socket map code.

See also cf/README about MSP and the section 684132943Sgshapiro "Providing SMTP AUTH Data when sendmail acts as Client". 685132943Sgshapiro Problem noted by Neil Rickert of Northern Illinois 686132943Sgshapiro University. 687132943Sgshapiro Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n 688132943Sgshapiro and -DSM_CONF_SETITIMER=0. Problem noted by Juergen Georgi 689132943Sgshapiro of RUS University of Stuttgart. 690132943Sgshapiro Fix bug in conversion from 8bit to quoted-printable. Problem found 691132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 692132943Sgshapiro Add support for LDAP recursion based on types given to attribute 693132943Sgshapiro specifications in an LDAP map definition. This allows 694132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 695132943Sgshapiro URL which will in turn be queried. See the ``LDAP 696132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 697132943Sgshapiro Based on patch from Andrew Baucom. 698132943Sgshapiro Extend the default LDAP specifications for AliasFile 699132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 700132943Sgshapiro include support for LDAP recursion via new attributes. 701132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 702132943Sgshapiro of cf/README for more information. 703132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 704132943Sgshapiro LDAP API/protocol version to use. The default depends on 705132943Sgshapiro the LDAP library. 706132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 707132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 708132943Sgshapiro and -p port. This also allows for the use of LDAP over 709132943Sgshapiro SSL and connections via named sockets if your LDAP 710132943Sgshapiro library supports it. 711132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 712132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 713132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 714132943Sgshapiro during a SMTP session then terminate it just like it is 715132943Sgshapiro done for too many bad SMTP commands. 716132943Sgshapiro Basic connection rate control support has been added: the daemon 717132943Sgshapiro maintains the number of incoming connections per client 718132943Sgshapiro IP address and total in the macros {client_rate} and 719132943Sgshapiro {total_rate}, respectively. These macros can be used 720132943Sgshapiro in the cf file to impose connection rate limits. 721132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 722132943Sgshapiro determines the length of the interval for which the 723132943Sgshapiro number of connections is stored. Based on patch from 724132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 725132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 726132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 727132943Sgshapiro If enabled by the new ruleset greet_pause (see 728132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 729132943Sgshapiro amount of time before sending the initial 220 SMTP 730132943Sgshapiro greeting. If any traffic is received before then, a 554 731132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 732132943Sgshapiro during that connection. 733132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 734132943Sgshapiro server could sleep for a very long time. Fix based on 735132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 736132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 737132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 738132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 739132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 740132943Sgshapiro misinterpret it as a permanent error. 741132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 742132943Sgshapiro all milters accepted the mail. This can increase 743132943Sgshapiro performance if many mails are rejected by milters due to 744132943Sgshapiro body scans. Based on patch from David F. Skoll. 745132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 746132943Sgshapiro header, whether provided by the client or generated by 747132943Sgshapiro sendmail. 748132943Sgshapiro New macro {client_connections} which contains the number of open 749132943Sgshapiro connections in the SMTP server for the client IP address. 750132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 751132943Sgshapiro Mines de Paris. 752132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 753132943Sgshapiro to prevent confusion caused by running sendmail stop 754132943Sgshapiro scripts two or more times, where the second and subsequent 755141858Sgshapiro runs would report misleading error messages about sendmail's 756132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 757132943Sgshapiro for a discussion of the implications of this, including 758132943Sgshapiro how to correct broken scripts which may have depended on 759132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 760132943Sgshapiro Support per-daemon input filter lists which override the default 761132943Sgshapiro filter list specified in InputMailFilters. The filters 762132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 763132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 764132943Sgshapiro your configuration relies on this behavior, you have to 765132943Sgshapiro add those names to class 'w' yourself. Problem noted 766132943Sgshapiro by Sander Eerkes. 767132943Sgshapiro Support message quarantining in the mail queue. Quarantined 768132943Sgshapiro messages are not run on normal queue displays or runs 769132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 770132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 771132943Sgshapiro The -q command line option now can specify which queue to display 772132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 773132943Sgshapiro operates on lost queue items. 774132943Sgshapiro Restricted mail queue runs and displays can be done based on the 775132943Sgshapiro quarantined reason using -qQtext to run or display 776132943Sgshapiro quarantined items if the quarantine reason contains the 777132943Sgshapiro given text. Similarly, -q!Qtext will run or display 778132943Sgshapiro quarantined items which do not have the given text in the 779132943Sgshapiro quarantine reason. 780132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 781132943Sgshapiro new -Q option. See doc/op/op.me for more information. 782132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 783132943Sgshapiro quarantine reason is shown in a new line prefixed by 784132943Sgshapiro "QUARANTINE:". 785132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 786132943Sgshapiro to quarantine messages in check_* (except check_compat) and 787132943Sgshapiro header check rulesets. The $: of the mailer triplet will 788132943Sgshapiro be used for the quarantine reason. 789132943Sgshapiro Add a new quarantine count to the mailstats collected. 790132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 791132943Sgshapiro message if it is quarantined. 792132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 793132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 794132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 795132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 796132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 797132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 798132943Sgshapiro lookup for the client IP address. Note: this is the same 799132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 800132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 801132943Sgshapiro recipients received so far in a transaction. 802132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 803132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 804132943Sgshapiro noted by Kai Schlichting. 805132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 806132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 807132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 808132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 809132943Sgshapiro Wolfhugel of France Telecom Oleane. 810132943Sgshapiro Do not silently truncate long strings in address rewriting. 811132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 812132943Sgshapiro Oceana Matrix Ltd. 813132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 814132943Sgshapiro support mutual authentication. From Kenneth Murchison of 815132943Sgshapiro Oceana Matrix Ltd. 816132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 817132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 818132943Sgshapiro format just like the STARTTLS related macros to avoid 819132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 820132943Sgshapiro Masarati of SysNet s.n.c. 821132943Sgshapiro New option AuthRealm to set the authentication realm that is 822132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 823132943Sgshapiro of the University of Manitoba. 824132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 825132943Sgshapiro successful, otherwise relaying would be allowed if 826132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 827132943Sgshapiro is active. 828132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 829132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 830132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 831132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 832132943Sgshapiro DIGEST-MD5 and LOGIN. 833132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 834132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 835132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 836132943Sgshapiro overwrite each other's pid files. 837132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 838132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 839132943Sgshapiro Wolfhugel of France Telecom. 840132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 841132943Sgshapiro LogLevel 12 or higher. 842132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 843132943Sgshapiro try to use the SMTP command VERB to propagate this option 844132943Sgshapiro to the MTA which in turn will show the delivery just like 845132943Sgshapiro it was done before the default 8.12 separation of MSP and 846132943Sgshapiro MTA. Based on patch by Per Hedeland. 847132943Sgshapiro If a daemon is refusing connections for longer than the time specified 848132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 849132943Sgshapiro to high load, log this information. Patch from John Beck 850132943Sgshapiro of Sun Microsystems. 851132943Sgshapiro Remove the ability for non-trusted users to raise the value of 852132943Sgshapiro CheckpointInterval on the command line. 853132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 854132943Sgshapiro subset of the functionality of the 's' flag. 855132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 856132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 857132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 858132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 859132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 860132943Sgshapiro causing subsequent messages to be sent instead of being 861132943Sgshapiro discarded. This also caused milter callbacks to be called 862132943Sgshapiro out of order after the SMTP session was reset. 863132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 864132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 865132943Sgshapiro further information. 866132943Sgshapiro New command line option -D logfile to send debug output to 867132943Sgshapiro the indicated log file instead of stdout. 868132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 869132943Sgshapiro queue return and warning times for delivery status 870132943Sgshapiro notifications. 871132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 872132943Sgshapiro at all. 873132943Sgshapiro Several more return values for ruleset srv_features have been added 874132943Sgshapiro to enable/disable certain features in the server per 875132943Sgshapiro connection. See doc/op/op.me for details. 876132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 877132943Sgshapiro for DaemonPortOptions. 878132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 879132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 880132943Sgshapiro of Northern Illinois University. 881132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 882132943Sgshapiro be tried as a last resort after all other fallbacks. This 883132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 884132943Sgshapiro view of inside the company, but an incomplete view of 885132943Sgshapiro outside). From John Beck of Sun Microsystems. 886132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 887132943Sgshapiro handshake. Based on patch by Andrey J. Melnikoff. 888132943Sgshapiro Remove deprecated -v option for PH map, use -k instead. Patch from 889132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 890132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 891132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 892132943Sgshapiro of the University of Illinois at Urbana-Champaign. 893132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 894132943Sgshapiro applications for use in the xxfi_eom() callback. 895132943Sgshapiro New macro {time} which contains the output of the time(3) function, 896132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 897132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 898132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 899132943Sgshapiro terminate the SMTP session with a 421 error message. 900132943Sgshapiro Get rid of dead code that tried to access the environment variable 901132943Sgshapiro HOSTALIASES. 902132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 903132943Sgshapiro compile with -DUSE_TTYPATH=1. 904132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 905132943Sgshapiro the header value passed in without balancing quotes, 906132943Sgshapiro parentheses, and angle brackets.

Cannot resolve PTR 1457102528Sgshapiro record for ..." if delay_checks is enabled. However, this 1458102528Sgshapiro modification causes a change of behavior if an IP net/address 1459102528Sgshapiro is listed in the access map with REJECT and a host/domain 1460102528Sgshapiro name is listed with OK or RELAY, hence it has been reversed 1461102528Sgshapiro such that the behavior of 8.12.3 is restored. The original 1462102528Sgshapiro change was made on request of Neil Rickert of Northern 1463102528Sgshapiro Illinois University, the side effect has been found by 1464102528Sgshapiro Stefaan Van Hoornick. 1465102528Sgshapiro CONFIG: Make sure delay_checks works even for sender addresses 1466102528Sgshapiro using the local hostname ($j) or domains in class {P}. 1467102528Sgshapiro Based on patch from Neil Rickert of Northern Illinois 1468102528Sgshapiro University. 1469102528Sgshapiro CONFIG: Fix temporary error handling for LDAP Routing lookups. 1470102528Sgshapiro Fix from Andrzej Filip. 1471102528Sgshapiro CONTRIB: New version of etrn.pl script and external man page 1472102528Sgshapiro (etrn.0) from John Beck of Sun Microsystems. 1473102528Sgshapiro LIBMILTER: Protect a free(3) operation from being called with a 1474102528Sgshapiro NULL pointer.

You may 151198841Sgshapiro want to do this in 8.12 by compiling with 151298841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 151398841Sgshapiro related programs to match locking techniques. 151498841Sgshapiro 151598121Sgshapiro8.12.4/8.12.4 2002/06/03 151698121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 151798121Sgshapiro can leave systems open to a local denial of service 151898121Sgshapiro attack.

In previous versions this could cause mail 161194334Sgshapiro not to be delivered if a queue file is repeatedly moved 161294334Sgshapiro by an external process whenever sendmail moved it back 161394334Sgshapiro into the right place. Some precautions have been taken 161494334Sgshapiro to avoid moving queue files if not really necessary. 161594334Sgshapiro sendmail may use links to refer to queue files and it 161694334Sgshapiro may store the path of data files in queue files. Hence 161794334Sgshapiro queue files should not be moved unless those internals 161894334Sgshapiro are understood and the integrity of the files is not 161994334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 162094334Sgshapiro University. 162194334Sgshapiro If an error mail is created, and the mail is split across different 162294334Sgshapiro queue directories, and SuperSafe is off, then write the mail 162394334Sgshapiro to disk before splitting it, otherwise an assertion is 162494334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 162594334Sgshapiro of INTERMETA. 162694334Sgshapiro Fix possible race condition that could cause sendmail to forget 162794334Sgshapiro running queues.

Problem noted by Jon 166694334Sgshapiro Lusky of ISS Atlanta. 166794334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 166894334Sgshapiro directories are used and mail is sent to a mailing list 166994334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 167094334Sgshapiro of Concordia University. 167194334Sgshapiro Fix class map parsing code if optional key is specified. Problem 167294334Sgshapiro found by Mario Nigrovic. 167394334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 167494334Sgshapiro incoming messages. A leading dot is always stripped by the 167594334Sgshapiro SMTP receiver regardless of whether or not it is followed by 167694334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 167794334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 167894334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 167994334Sgshapiro Elvers. 168094334Sgshapiro Correct the statistics gathered for total number of connections. 168194334Sgshapiro Instead of being the exact same number as the total number 168294334Sgshapiro of messages (T line in mailstats) it now represents the 168394334Sgshapiro total number of TCP connections. 168494334Sgshapiro Be more explicit about syntax errors in addresses, especially 168594334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 168694334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 168794334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 168894334Sgshapiro are used.

Based on 169694334Sgshapiro patch by Bryan Costales. 169794334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 169894334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 169994334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 170094334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 170194334Sgshapiro errors. By doing so, the host was marked as having a 170294334Sgshapiro temporary problem and other mail destined for that host was 170394334Sgshapiro queued for the next queue run. Problem noted by Fletcher 170494334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 170594334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 170694334Sgshapiro and Neil Rickert of Northern Illinois University. 170794334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 170894334Sgshapiro which drop the connection instead of responding to the 170994334Sgshapiro command). 171094334Sgshapiro Portability: 171194334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 171298121Sgshapiro available. 171394334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 171494334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 171594334Sgshapiro settings. Patch from Elias Halldor Agustsson of 171694334Sgshapiro Skyrr. 171794334Sgshapiro Fix dependency building on Mac OS X and Darwin.

From 172194334Sgshapiro Rajesh Somasund of Hewlett-Packard. 172294334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 172394334Sgshapiro SMTP AUTH information. This feature was actually added in 172494334Sgshapiro 8.12.0 but a release note was not included. 172594334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 172694334Sgshapiro parameter is set and the LDAP lookup returns a temporary 172794334Sgshapiro error. 172894334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 172994334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 173094334Sgshapiro Krzysztof Oledzki. 173194334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 173294334Sgshapiro initialization as aliases are not needed for the MSP. 173394334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 173494334Sgshapiro is in use. Patch from Andrzej Filip. 173594334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 173694334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 173794334Sgshapiro This will only have an effect if a parameter is specified, 173894334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 173994334Sgshapiro it is embedded in square brackets. Problem noted by 174094334Sgshapiro Theo Van Dinter of Collective Technologies. 174194334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 174294334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 174394334Sgshapiro to allow for the proper time zone on systems where the 174494334Sgshapiro default results in misleading time stamps. That is, syslog 174594334Sgshapiro time stamps and Date headers on submitted mail will use the 174694334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 174794334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 174894334Sgshapiro by Neil Rickert of Northern Illinois University. 174994334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 175094334Sgshapiro binary.

Problem noted by Jorg Bielak from Coastal Web 182390792Sgshapiro Online. 182490792Sgshapiro For systems on which stat(2) does not return a value for st_blksize 182590792Sgshapiro that is the "optimal blocksize for I/O" three new compile 182690792Sgshapiro time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF, 182790792Sgshapiro and SM_IO_MAX_BUF, which define an upper limit for 182890792Sgshapiro regular files, and a lower and upper limit for other file 182990792Sgshapiro types, respectively. 183090792Sgshapiro Fix a potential deadlock if two events are supposed to occur at 183190792Sgshapiro exactly the same time.

Problem noted by Bjoern Voigt of TU Berlin. 184990792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 185090792Sgshapiro server gets stuck while processing that command. Problem 185190792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 185290792Sgshapiro In addition to printing errors when parsing recipients during 185390792Sgshapiro command line invocations log them to make it simpler 185490792Sgshapiro to understand possible DSNs to postmaster. 185590792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 185690792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 185790792Sgshapiro instead of forcing localhost. 185890792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 185990792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 186090792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 186190792Sgshapiro noted by Neil Rickert of Northern Illinois University. 186290792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 186390792Sgshapiro dropping the connection during an SMTP transaction, stop 186490792Sgshapiro sending commands. This prevents bogus "Bad file number" 186590792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 186690792Sgshapiro Worcester Polytechnic Institute. 186790792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 186890792Sgshapiro almost always too small; do not guess the size at all. 186990792Sgshapiro New VENDOR_DEC for Compaq/DEC.

Problem 194790792Sgshapiro found by Michal Zalewski. 194890792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 194990792Sgshapiro privileges by disabling debugging (command line -d flag) 195090792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 195190792Sgshapiro used. Suggested by Michal Zalewski. 195290792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 195390792Sgshapiro Problem found by Michal Zalewski. 195490792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 195590792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 195690792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 195790792Sgshapiro If debugging is turned on (-d0.10) print not just the default 195890792Sgshapiro values for configuration file and pid file but also the 195990792Sgshapiro selected values. Problem noted by Brad Chapman. 196090792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 196190792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 196290792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 196390792Sgshapiro this only applied to hostname canonification. Problem 196490792Sgshapiro noted by Bill Fenner of AT&T Research. 196590792Sgshapiro Ignore comments in NIS host records when trying to find the 196690792Sgshapiro canonical name for a host. 196790792Sgshapiro When sendmail has extra privileges, limit mail submission command 196890792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 196990792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.).

You need to create a new user and 201290792Sgshapiro a new group before installing sendmail (both called smmsp by 201390792Sgshapiro default). The installation process tries to install 201490792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 201590792Sgshapiro default.

Suggested 202690792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 202790792Sgshapiro (IdS). 202890792Sgshapiro Fixed problem of a global variable being used for a timeout jump 202990792Sgshapiro point where the variable could become overused for more than 203090792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 203190792Sgshapiro a corrupted stack causing a core dump. The timeout is now 203290792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 203390792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 203490792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 203590792Sgshapiro checks (group ID of RunAsUser). This allows use of a 203690792Sgshapiro set-group-ID sendmail binary for initial message submission 203790792Sgshapiro and no set-user-ID root sendmail is needed. For details 203890792Sgshapiro see sendmail/SECURITY. 203990792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 204090792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 204190792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 204290792Sgshapiro with a fallback of sendmail.cf as configuration file. See 204390792Sgshapiro sendmail/SECURITY. 204490792Sgshapiro New configuration file option UseMSP to allow group writable queue 204590792Sgshapiro files if the group is the same as that of a set-group-ID 204690792Sgshapiro sendmail binary. See sendmail/SECURITY. 204790792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 204890792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 204990792Sgshapiro is sendmail.cf (to be backward compatible). This selection 205090792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 205190792Sgshapiro file: client or mta). See sendmail/SECURITY. 205290792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 205390792Sgshapiro command has been removed. 205490792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 205590792Sgshapiro at compile time or per host (ruleset). 205690792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 205790792Sgshapiro used to look up local mail recipients; the default value 205890792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 205990792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 206090792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 206190792Sgshapiro long, to accomodate envelope splitting. File systems with 206290792Sgshapiro a 14 character file name length limit are no longer 206390792Sgshapiro supported. 206490792Sgshapiro Recipient list used for delivery now gets internally ordered by 206590792Sgshapiro hostsignature (character string version of MX RR). This orders 206690792Sgshapiro recipients for the same MX RR's together meaning smaller 206790792Sgshapiro portions of the list need to be scanned (instead of the whole 206890792Sgshapiro list) each delivery() pass to determine piggybacking. The 206990792Sgshapiro significance of the change is better the larger the recipient 207090792Sgshapiro list. Hostsignature is now created during recipient list 207190792Sgshapiro creation rather than just before delivery. 207290792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 207390792Sgshapiro piggybacking (called coincidental) extended to coattail 207490792Sgshapiro piggybacking. Rather than complete MX RR matching 207590792Sgshapiro (coincidental) piggybacking is done if just the lowest value 207690792Sgshapiro preference matches (coattail). 207790792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 207890792Sgshapiro try other MX hosts if available. 207990792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 208090792Sgshapiro outgoing (client-side) SMTP Authentication. 208190792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 208290792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 208390792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 208490792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 208590792Sgshapiro A new ruleset authinfo can be used to return client side 208690792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 208790792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 208890792Sgshapiro removed in future versions. 208990792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 209090792Sgshapiro requires 334. Mercury 1.48 is a known offender. 209190792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 209290792Sgshapiro for the security layer in SMTP AUTH (SASL). See 209390792Sgshapiro doc/op/op.me for details. 209490792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 209590792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 209690792Sgshapiro signed the presented certificate, the CN and the MD5 hash 209790792Sgshapiro of the presented certificate, respectively. 209890792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 209990792Sgshapiro New ruleset srv_features to enable/disable certain features in the 210090792Sgshapiro server per connection. See doc/op/op.me for details. 210190792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 210290792Sgshapiro recipient; useful to decide whether a conection is secure 210390792Sgshapiro enough on a per recipient basis. 210490792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 210590792Sgshapiro for STARTTLS. 210690792Sgshapiro If no certificate has been requested, the macro {verify} has the 210790792Sgshapiro value "NOT". 210890792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 210990792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 211090792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 211190792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 211290792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 211390792Sgshapiro really required. This change results in a noticable 211490792Sgshapiro performance gains on most machines. Moreover, if shared 211590792Sgshapiro memory is in use, reuse the key several times. 211690792Sgshapiro Add queue groups which can be used to group queue directories with 211790792Sgshapiro the same behavior together. See doc/op/op.me for details. 211890792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 211990792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 212090792Sgshapiro are initially sorted which may result in faster envelope 212190792Sgshapiro splitting. If the mail is submitted directly from the 212290792Sgshapiro command line, then the value also limits the number of 212390792Sgshapiro processes to deliver the envelopes; if more envelopes are 212490792Sgshapiro created they are only queued up and must be taken care of 212590792Sgshapiro by a queue run. 212690792Sgshapiro The check for 'enough disk space' now pays attention to which file 212790792Sgshapiro system each queue directory resides in. 212890792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 212990792Sgshapiro New option QueueFileMode for the default permissions of queue files. 213090792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 213190792Sgshapiro group (one or more queues in a multi-queue environment 213290792Sgshapiro collected together) to process the same work list at the 213390792Sgshapiro same time. 213490792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 213590792Sgshapiro active queue runner processes. 213690792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 213790792Sgshapiro runners per queue group. 213890792Sgshapiro Queue member selection by substring pattern matching now allows 213990792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 214090792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 214190792Sgshapiro of the queue that match during processing. 214290792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 214390792Sgshapiro periodically forking a child to process the queue, a single 214490792Sgshapiro child is forked for each queue that sleeps between queue 214590792Sgshapiro runs. A SIGHUP signal can be sent to restart this 214690792Sgshapiro persistent queue runner. 214790792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 214890792Sgshapiro sendmail process which only runs the queue at an interval: 214990792Sgshapiro sendmail -q15m). 215090792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 215190792Sgshapiro Proposed by Thom O'Connor. 215290792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 215390792Sgshapiro unless the new -qf option or -v is used. 215490792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 215590792Sgshapiro several queue runners are started by hand to avoid contention. 215690792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 215790792Sgshapiro of the qf file (older entries first). 215890792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 215990792Sgshapiro a client to specify an amount of time within which an e-mail 216090792Sgshapiro should be delivered. New option DeliverByMin added to set the 216190792Sgshapiro minimum amount of time or disable the extension. 216290792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 216390792Sgshapiro not allowed unless escaped or quoted. 216490792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 216590792Sgshapiro by Leif Johansson of Stockholm University, which was based on 216690792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 216790792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 216890792Sgshapiro Technology, Stockholm, Sweden. 216990792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 217090792Sgshapiro behavior (no MX lookups), put the name in square brackets. 217190792Sgshapiro Proposed by Thom O'Connor. 217290792Sgshapiro Use shared memory to store free space of filesystems that are used 217390792Sgshapiro for queues, if shared memory is available and if a key is set 217490792Sgshapiro via SharedMemoryKey. This minimizes the number of system 217590792Sgshapiro calls to check the available space. See doc/op/op.me for 217690792Sgshapiro details. 217790792Sgshapiro If shared memory is compiled in the option -bP can be used to print 217890792Sgshapiro the number of entries in the queue(s). 217990792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 218090792Sgshapiro and the usual documentation for details. 218190792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 218290792Sgshapiro Remove '-U' (initial user submission) command line option as 218390792Sgshapiro announced in 8.10. 218490792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 218590792Sgshapiro New macro {addr_type} which contains whether the current address is 218690792Sgshapiro an envelope sender or recipient address. Suggested by 218790792Sgshapiro Neil Rickert of Northern Illinois University. 218890792Sgshapiro Two new options for host maps: -d (retransmission timeout), 218990792Sgshapiro -r (number of retries). 219090792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 219190792Sgshapiro separator such that a lookup can return both an attribute 219290792Sgshapiro and value separated by the given separator. 219390792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 219490792Sgshapiro to map class arith. 219590792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 219690792Sgshapiro (errors that occur when sending an error message) are dropped. 219790792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 219890792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 219990792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 220090792Sgshapiro requirements for files containing secret keys. This is 220190792Sgshapiro necessary for the MSP if client authentification is used. 220290792Sgshapiro Properly handle quoted filenames for class files (to allow for 220390792Sgshapiro filenames with spaces). 220490792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 220590792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 220690792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 220790792Sgshapiro {if_addr_out} address of interface of outgoing connection. 220890792Sgshapiro {if_family_out} family of interface of outgoing connection. 220990792Sgshapiro The latter two are only set if the interface does not belong 221090792Sgshapiro to the loopback net. 221190792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 221290792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 221390792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 221490792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 221590792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 221690792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 221790792Sgshapiro all connections for a single delivery attempt to succeed. 221890792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 221990792Sgshapiro a threshold number of recipients has been rejected (option 222090792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 222190792Sgshapiro Development Group. 222290792Sgshapiro New option DelayLA to delay connections if the load averages 222390792Sgshapiro exceeds the specified value. The default of 0 does not 222490792Sgshapiro change the previous behavior. A value greater than 0 222590792Sgshapiro will cause sendmail to sleep for one second on most 222690792Sgshapiro SMTP commands and before accepting connections if that 222790792Sgshapiro load average is exceeded. 222890792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 222990792Sgshapiro recipients that are sent during a connection to a mailer. 223090792Sgshapiro This also introduces a new mailer field 'r' which defines 223190792Sgshapiro the maximum number of recipients (defaults to 100). 223290792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 223390792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 223490792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 223590792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 223690792Sgshapiro instead. 223790792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 223890792Sgshapiro builtin mailer pathnames. Use TCP instead. 223990792Sgshapiro PH map code updated to use the new libphclient API instead of the 224090792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 224190792Sgshapiro University of Illinois at Urbana-Champaign. 224290792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 224390792Sgshapiro for direct (command line) submissions. 224490792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 224590792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 224690792Sgshapiro Hagino of the KAME Project. 224790792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 224890792Sgshapiro whose content is rewritten similar to Reply-To:. 224990792Sgshapiro Proposed by Andrzej Filip. 225090792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 225190792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 225290792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 225390792Sgshapiro AUTH/STARTTLS related logfile entries. 225490792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 225590792Sgshapiro before logging. 225690792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 225790792Sgshapiro (at LogLevel 9/10 or higher). 225890792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 225990792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 226090792Sgshapiro in which most commands are rejected due to check_relay or 226190792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 226290792Sgshapiro Change logging format for cloned envelopes to be similar to that for 226390792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 226490792Sgshapiro of the Universitat Regensburg. 226590792Sgshapiro Added libsm, a C library of general purpose abstractions including 226690792Sgshapiro assertions, tracing and debugging with named debug categories, 226790792Sgshapiro exception handling, malloc debugging, resource pools, 226890792Sgshapiro portability abstractions, and an extensible buffered I/O 226990792Sgshapiro package. It will at some point replace libsmutil. 227090792Sgshapiro See libsm/index.html for details. 227190792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 227290792Sgshapiro care of by fork() and exit(). 227390792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 227490792Sgshapiro more consistent portablity amongst different platforms 227590792Sgshapiro new and old (from new libsm). 227690792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 227790792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 227890792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 227990792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 228090792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 228190792Sgshapiro synchronizations calls. 228290792Sgshapiro Add per-recipient status information to mailq -v output. 228390792Sgshapiro T_ANY queries are no longer used by sendmail. 228490792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 228590792Sgshapiro too (see include/sm/cdefs.h for more info). 228690792Sgshapiro sendmail -d now has general support for named debug categories. 228790792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 228890792Sgshapiro for details. 228990792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 229090792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 229190792Sgshapiro generated by this condition were illegal (not RFC conform). 229290792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 229390792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 229490792Sgshapiro mailer and the recipient has hence been rejected during the 229590792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 229690792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 229790792Sgshapiro that do not have postmaster defined. If an email was sent 229890792Sgshapiro from an address to which a DSN cannot be returned and 229990792Sgshapiro in which at least one recipient address is non-deliverable, 230090792Sgshapiro then that email had been delivered in each queue run. 230190792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 230290792Sgshapiro degli Studi dell'Insubria. 230390792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 230490792Sgshapiro i.e., the corresponding code is always compiled in now. 230590792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 230690792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 230790792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 230890792Sgshapiro attempting to canonify a hostname, some broken nameservers 230990792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 231090792Sgshapiro lookups. If you want to excuse this behavior, use this new 231190792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 231290792Sgshapiro Mark Roth of the University of Illinois at 231390792Sgshapiro Urbana-Champaign. 231490792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 231590792Sgshapiro noted by Joy Latten of IBM. 231690792Sgshapiro ConnectionRateThrottle limits the number of connections per second 231790792Sgshapiro to each daemon individually, not the overall number of 231890792Sgshapiro connections. 231990792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 232090792Sgshapiro sendmail to use a default alias schema as outlined in the 232190792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 232290792Sgshapiro cf/README. 232390792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 232490792Sgshapiro the first character after the class name is not a '/' or a 232590792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 232690792Sgshapiro rest of the line will be parsed as a map lookup. This 232790792Sgshapiro allows classes to be filled via a map lookup. See op.me 232890792Sgshapiro for more syntax information. Specifically, this can be 232990792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 233090792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 233190792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 233290792Sgshapiro example). 233390792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 233490792Sgshapiro the default schema used in the above two items. 233590792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 233690792Sgshapiro warning if a program being run from a mailer or file class 233790792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 233890792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 233990792Sgshapiro if a program being run from a mailer or file class 234090792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 234190792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 234290792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 234390792Sgshapiro (without quotes) will disable this and return to the 234490792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 234590792Sgshapiro Suggested by Bryan Stansell of GNAC. 234690792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 234790792Sgshapiro HELO/EHLO commands. 234890792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 234990792Sgshapiro possible protocol family which may be used for outgoing 235090792Sgshapiro connections. Restrictions placed on one family only affect 235190792Sgshapiro outgoing connections on that particular family. Because of 235290792Sgshapiro this change, the ${client_flags} macro is not set until the 235390792Sgshapiro connection is established. Based on patch from Motonori 235490792Sgshapiro Nakamura of Kyoto University. 235590792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 235690792Sgshapiro when the -bv option is given by users who are neither root 235790792Sgshapiro nor the TrustedUser so users can not read private aliases, 235890792Sgshapiro forwards, or :include: files. It also will override the -v 235990792Sgshapiro (verbose) command line option. 236090792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 236190792Sgshapiro address can't be used for the outgoing connection, fall 236290792Sgshapiro back to the settings in ClientPortOptions (if set). 236390792Sgshapiro Problem noted by John Beck of Sun Microsystems. 236490792Sgshapiro New named config file rule check_data for DATA command (input: 236590792Sgshapiro number of recipients). Based on patch from Mark Roth of 236690792Sgshapiro the University of Illinois at Urbana-Champaign. 236790792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 236890792Sgshapiro can be specified using the '#' option character. For 236990792Sgshapiro example, 'ETRN #queuegroup'. 237090792Sgshapiro If an LDAP server times out or becomes unavailable, close the 237190792Sgshapiro current connection and reopen to get to one of the fallback 237290792Sgshapiro servers. Patch from Paul Hilchey of the University of 237390792Sgshapiro British Columbia. 237490792Sgshapiro Make default error number on $#error messages 550 instead of 501 237590792Sgshapiro because 501 is not allowed on all commands. 237690792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 237790792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 237890792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 237990792Sgshapiro if required. 238090792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 238190792Sgshapiro class instead. 238290792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 238390792Sgshapiro "IPv6:" tag to identify the address properly. For example, 238490792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 238590792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 238690792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 238790792Sgshapiro MTA is running. For example, during a queue run. 238890792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 238990792Sgshapiro RES_USE_INET6 resolver option. Based on patch from Rick 239090792Sgshapiro Nelson of IBM. 239190792Sgshapiro The maximum number of commands before the MTA slows down when too 239290792Sgshapiro many "light weight" commands have been received are now 239390792Sgshapiro configurable during compile time. The current values and 239490792Sgshapiro their defaults are: 239590792Sgshapiro MAXBADCOMMANDS 25 unknown commands 239690792Sgshapiro MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 239790792Sgshapiro MAXHELOCOMMANDS 3 HELO, EHLO 239890792Sgshapiro MAXVRFYCOMMANDS 6 VRFY, EXPN 239990792Sgshapiro MAXETRNCOMMANDS 8 ETRN 240090792Sgshapiro Setting a value to 0 disables the check. Patch from Bryan 240190792Sgshapiro Costales of SL3D, Inc. 240290792Sgshapiro The header syntax H?${MyMacro}?X-My-Header: now not only checks if 240390792Sgshapiro ${MyMacro} is defined but also that it is not empty. 240490792Sgshapiro Properly quote usernames with special characters if they are used 240590792Sgshapiro in headers. Problem noted by Kari Hurtta of the Finnish 240690792Sgshapiro Meteorological Institute. 240790792Sgshapiro Be sure to include the proper Final-Recipient: DSN header in bounce 240890792Sgshapiro messages for messages for mailing list expanded addresses 240990792Sgshapiro which are not delivered on the initial attempt. 241090792Sgshapiro Do not treat errors as sticky when doing delivery via LMTP after 241190792Sgshapiro the final dot has been sent to avoid affecting future 241290792Sgshapiro deliveries. Problem reported by Larry Greenfield of CMU. 241390792Sgshapiro New compile time flag REQUIRES_DIR_FSYNC which turns on support for 241490792Sgshapiro file systems that require to call fsync() for a directory 241590792Sgshapiro if the meta-data in it has been changed. This should be 241690792Sgshapiro set at least for ReiserFS; it is enabled by default for Linux. 241790792Sgshapiro See sendmail/README for further information. 241890792Sgshapiro Avoid file locking deadlock when updating the statistics file if 241990792Sgshapiro sendmail is signaled to terminate. Problem noted by 242090792Sgshapiro Christophe Wolfhugel of France Telecom. 242190792Sgshapiro Set the $c macro (hop count) as it is being set instead of when the 242290792Sgshapiro envelope is initialized.

Based on 261290792Sgshapiro patch from Doug Hardie of the Los Angeles Free-Net. 261390792Sgshapiro MAILSTATS: New command line option -P which acts the same as -p but 261490792Sgshapiro doesn't truncate the statistics file. 261590792Sgshapiro MAKEMAP: Add new option -t to specify a different delimiter 261690792Sgshapiro instead of white space. 261790792Sgshapiro RMAIL: Invoke sendmail with '-G' to indicate this is a gateway 261890792Sgshapiro submission. Problem noted by Kari Hurtta of the Finnish 261990792Sgshapiro Meteorological Institute. 262090792Sgshapiro SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later. 262190792Sgshapiro VACATION: Change Auto-Submitted: header value from auto-generated to 262290792Sgshapiro auto-replied. From Kenneth Murchison of Oceana Matrix Ltd. 262390792Sgshapiro VACATION: New option -d to send error/debug messages to stdout 262490792Sgshapiro instead of syslog. 262590792Sgshapiro VACATION: New option -U which prevents the attempt to lookup login 262690792Sgshapiro in the password file. The -f and -m options must be used 262790792Sgshapiro to specify the database and message file since there is no 262890792Sgshapiro home directory for the default settings for these options. 262990792Sgshapiro VACATION: Vacation now uses the libsm mbdb package to look up 263090792Sgshapiro local mail recipients; it reads the MailboxDatabase option 263190792Sgshapiro from the sendmail.cf file. New option -C cffile which 263290792Sgshapiro specifies the path of the sendmail.cf file. 263390792Sgshapiro New Directories: 263490792Sgshapiro libmilter/docs 263590792Sgshapiro New Files: 263690792Sgshapiro cf/cf/README 263790792Sgshapiro cf/cf/submit.cf 263890792Sgshapiro cf/cf/submit.mc 263990792Sgshapiro cf/feature/authinfo.m4 264090792Sgshapiro cf/feature/compat_check.m4 264190792Sgshapiro cf/feature/enhdnsbl.m4 264290792Sgshapiro cf/feature/msp.m4 264390792Sgshapiro cf/feature/local_no_masquerade.m4 264490792Sgshapiro cf/feature/lookupdotdomain.m4 264590792Sgshapiro cf/feature/preserve_luser_host.m4 264690792Sgshapiro cf/feature/preserve_local_plus_detail.m4 264790792Sgshapiro cf/feature/queuegroup.m4 264890792Sgshapiro cf/sendmail.schema 264990792Sgshapiro contrib/dnsblaccess.m4 265090792Sgshapiro devtools/M4/UNIX/sm-test.m4 265190792Sgshapiro devtools/OS/OpenUNIX.5.i386 265290792Sgshapiro editmap/* 265390792Sgshapiro include/sm/* 265490792Sgshapiro libsm/* 265590792Sgshapiro libsmutil/cf.c 265690792Sgshapiro libsmutil/err.c 265790792Sgshapiro sendmail/SECURITY 265890792Sgshapiro sendmail/TUNING 265990792Sgshapiro sendmail/bf.c 266090792Sgshapiro sendmail/bf.h 266190792Sgshapiro sendmail/sasl.c 266290792Sgshapiro sendmail/sm_resolve.c 266390792Sgshapiro sendmail/sm_resolve.h 266490792Sgshapiro sendmail/tls.c 266590792Sgshapiro Deleted Files: 266690792Sgshapiro cf/feature/rbl.m4 266790792Sgshapiro cf/ostype/aix2.m4 266890792Sgshapiro devtools/OS/AIX.2 266990792Sgshapiro include/sendmail/cdefs.h 267090792Sgshapiro include/sendmail/errstring.h 267190792Sgshapiro include/sendmail/useful.h 267290792Sgshapiro libsmutil/errstring.c 267390792Sgshapiro sendmail/bf_portable.c 267490792Sgshapiro sendmail/bf_portable.h 267590792Sgshapiro sendmail/bf_torek.c 267690792Sgshapiro sendmail/bf_torek.h 267790792Sgshapiro sendmail/clock.c 267890792Sgshapiro Renamed Files: 267990792Sgshapiro cf/cf/generic-solaris2.mc => cf/cf/generic-solaris.mc 268090792Sgshapiro cf/cf/generic-solaris2.cf => cf/cf/generic-solaris.cf 268190792Sgshapiro cf/ostype/aux.m4 => cf/ostype/a-ux.m4 268290792Sgshapiro 2683120256Sgshapiro8.11.7/8.11.7 2003/03/29 2684120256Sgshapiro SECURITY: Fix a remote buffer overflow in header parsing by 2685120256Sgshapiro dropping sender and recipient header comments if the 2686120256Sgshapiro comments are too long.

If sendmail needs to drop 317364562Sgshapiro these privileges and the operating system doesn't set the 317464562Sgshapiro saved-uid as well, exit with an error. Problem noted by 317564562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 317664562Sgshapiro SECURITY: sendmail depends on snprintf() NUL terminating the string 317764562Sgshapiro it populates. It is possible that some broken 317864562Sgshapiro implementations of snprintf() exist that do not do this. 317964562Sgshapiro Systems in this category should compile with 318064562Sgshapiro -DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your 318164562Sgshapiro system and report broken implementations to 318264562Sgshapiro sendmail-bugs@sendmail.org and your OS vendor. Problem 318364562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 318464562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 318564562Sgshapiro Implementation influenced by the example programs of 318664562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 318764562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 318864562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 318964562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 319064562Sgshapiro cf/README and doc/op/op.*. 319164562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 319264562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 319364562Sgshapiro ${server_name}, and ${server_addr}. These are documented 319464562Sgshapiro in cf/README and doc/op/op.*. 319564562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 319664562Sgshapiro random data. 319764562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 319864562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 319964562Sgshapiro try to use STARTTLS despite the security problems. 320064562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 320164562Sgshapiro support encryption. Based on code contributed by Tim 320264562Sgshapiro Martin of CMU. 320364562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 320464562Sgshapiro strength factor. 320564562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 320664562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 320764562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 320864562Sgshapiro of CMU. 320964562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 321064562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 321164562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 321264562Sgshapiro Fix the default family selection for DaemonPortOptions. As 321364562Sgshapiro documented, unless a family is specified in a 321464562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 321564562Sgshapiro also the default if no DaemonPortOptions value is set. 321664562Sgshapiro Therefore, IPv6 users should configure additional sockets 321764562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 321864562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 321964562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 322064562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 322164562Sgshapiro the interface information for an outgoing connection. 322264562Sgshapiro Not doing so was creating a mismatch between the socket 322364562Sgshapiro family and address used in subsequent connections if the 322464562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 322564562Sgshapiro by John Beck of Sun Microsystems. 322664562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 322764562Sgshapiro family based on the IP address. ${if_family} is no longer 322864562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 322964562Sgshapiro of Sun Microsystems. 323064562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 323164562Sgshapiro macros for both the incoming interface address/family and 323264562Sgshapiro the outgoing interface address/family. In order for M=b 323364562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 323464562Sgshapiro the incoming information in the queue file for later 323564562Sgshapiro delivery attempts. 323664562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 323764562Sgshapiro responses to commands. Problem noted by Jeff Wasilko of 323864562Sgshapiro smoe.org. 323964562Sgshapiro Add more vigilance in checking for putc() errors on output streams 324064562Sgshapiro to protect from a bug in Solaris 2.6's putc(). Problem 324164562Sgshapiro noted by Graeme Hewson of Oracle. 324264562Sgshapiro The LDAP map -n option (return attribute names only) wasn't working. 324364562Sgshapiro Problem noted by Ajay Matia. 324464562Sgshapiro Under certain circumstances, an address could be listed as deferred 324564562Sgshapiro but would be bounced back to the sender as failed to be 324664562Sgshapiro delivered when it really should have been queued. Problem 324764562Sgshapiro noted by Allan E Johannesen of Worcester Polytechnic Institute. 324864562Sgshapiro Prevent a segmentation fault in a child SMTP process from getting 324964562Sgshapiro the SMTP transaction out of sync. Problem noted by Per 325064562Sgshapiro Hedeland of Ericsson. 325164562Sgshapiro Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT 325264562Sgshapiro is defined to avoid a core dump due to incompatibilities 325364562Sgshapiro between sfio and stdio. Problem noted by Neil Rickert 325464562Sgshapiro of Northern Illinois University. 325564562Sgshapiro Don't log useless envelope ID on initial connection log. Problem 325664562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological Institute. 325764562Sgshapiro Convert the free disk space shown in a control socket status query 325864562Sgshapiro to kilobyte units. 325964562Sgshapiro If TryNullMXList is True and there is a temporary DNS failure 326064562Sgshapiro looking up the hostname, requeue the message for a later 326164562Sgshapiro attempt. Problem noted by Ari Heikkinen of Pohjois-Savo 326264562Sgshapiro Polytechnic. 326364562Sgshapiro Under the proper circumstances, failed connections would be recorded 326464562Sgshapiro as "Bad file number" instead of "Connection failed" in the 326564562Sgshapiro queue file and persistent host status. Problem noted by 326664562Sgshapiro Graeme Hewson of Oracle. 326764562Sgshapiro Avoid getting into an endless loop if a non-hoststat directory exists 326864562Sgshapiro within the hoststatus directory (e.g., lost+found). 326964562Sgshapiro Patch from Valdis Kletnieks of Virginia Tech. 327064562Sgshapiro Make sure Timeout.queuereturn=now returns a bounce message to the 327164562Sgshapiro sender. Problem noted by Per Hedeland of Ericsson. 327264562Sgshapiro If a message data file can't be opened at delivery time, panic and 327364562Sgshapiro abort the attempt instead of delivering a message that 327464562Sgshapiro states "<<< No Message Collected >>>". 327564562Sgshapiro Fixup the GID checking code from 8.10.2 as it was overly 327664562Sgshapiro restrictive.

This option and 354964562Sgshapiro its use is deprecated and will be removed from a future 355064562Sgshapiro version of sendmail. 355164562Sgshapiro SECURITY: Make sure all file descriptors (besides stdin, stdout, and 355264562Sgshapiro stderr) are closed before restarting sendmail. Problem noted 355364562Sgshapiro by Michal Zalewski of the "Internet for Schools" project 355464562Sgshapiro (IdS). 355564562Sgshapiro Begin using /etc/mail/ for sendmail related files. This affects 355664562Sgshapiro a large number of files. See cf/README for more details. 355764562Sgshapiro The directory structure of the distribution has changed slightly 355864562Sgshapiro for easier code sharing among the programs. 355964562Sgshapiro Support SMTP AUTH (see RFC 2554). New macros for this purpose 356064562Sgshapiro are ${auth_authen}, ${auth_type}, and ${auth_author} 356164562Sgshapiro which hold the client's authentication credentials, 356264562Sgshapiro the mechanism used for authentication, and the 356364562Sgshapiro authorization identity (i.e., the AUTH= parameter if 356464562Sgshapiro supplied). Based on code contributed by Tim Martin of CMU. 356564562Sgshapiro On systems which use the Torek stdio library (all of the BSD 356664562Sgshapiro distributions), use memory-buffered files to reduce 356764562Sgshapiro file system overhead by not creating temporary files on 356864562Sgshapiro disk.

Contributed by Exactis.com, Inc. 357564562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 357664562Sgshapiro now listen on several different ports. Use: 357764562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 357864562Sgshapiro to run a Message Submission Agent (MSA); this is turned 357964562Sgshapiro on by default in m4-generated .cf files; it can be turned 358064562Sgshapiro off with FEATURE(`no_default_msa'). 358164562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 358264562Sgshapiro begin using RFC 2476 Message Submission for initial user 358364562Sgshapiro message submission. XUSR may disappear from a future release. 358464562Sgshapiro The new '-G' (relay (gateway) submission) command line option 358564562Sgshapiro indicates that the message being submitted from the command 358664562Sgshapiro line is for relaying, not initial submission. This means 358764562Sgshapiro the message will be rejected if the addresses are not fully 358864562Sgshapiro qualified and no canonicalization will be done. Future 358964562Sgshapiro releases may even reject improperly formed messages. 359064562Sgshapiro The '-U' (initial user submission) command line option is 359164562Sgshapiro deprecated and may be removed from a future release. 359264562Sgshapiro Mail user agents should begin using '-G' to indicate that 359364562Sgshapiro this is a relay submission (the inverse of -U). 359464562Sgshapiro The next release of sendmail will assume that any message submitted 359564562Sgshapiro from the command line is an initial user submission and act 359664562Sgshapiro accordingly. 359764562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 359864562Sgshapiro program or deliver to file as the owner of that file, the 359964562Sgshapiro address is marked as unsafe. This means if RunAsUser is 360064562Sgshapiro set, users won't be able to use programs or delivery to 360164562Sgshapiro files in their .forward files. Administrators can override 360264562Sgshapiro this by setting the DontBlameSendmail option to the new 360364562Sgshapiro setting NonRootSafeAddr. 360464562Sgshapiro Allow group or world writable directories if the sticky bit is set 360564562Sgshapiro on the directory and DontBlameSendmail is set to 360664562Sgshapiro TrustStickyBit.

To use multiple queues, supply 363964562Sgshapiro a QueueDirectory option value ending with an asterisk. For 364064562Sgshapiro example, /var/spool/mqueue/q* will use all of the 364164562Sgshapiro directories or symbolic links to directories beginning with 364264562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 364364562Sgshapiro mind, the queue directory structure should not be changed 364464562Sgshapiro while sendmail is running. Queue runs create a separate 364564562Sgshapiro process for running each queue unless the verbose flag is 364664562Sgshapiro given on a non-daemon queue run. New items are randomly 364764562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 364864562Sgshapiro Support different directories for qf, df, and xf queue files; if 364964562Sgshapiro subdirectories or symbolic links to directories of those names 365064562Sgshapiro exist in the queue directories, they are used for the 365164562Sgshapiro corresponding queue files. Keep in mind, the queue 365264562Sgshapiro directory structure should not be changed while sendmail is 365364562Sgshapiro running. Proposed by Mathias Koerber of Singapore 365464562Sgshapiro Telecommunications Ltd. 365564562Sgshapiro New queue file naming system which uses a filename guaranteed to be 365664562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 365764562Sgshapiro without fancy file system locking. Queued items can be 365864562Sgshapiro moved between queues easily. Contributed by Exactis.com, 365964562Sgshapiro Inc. 366064562Sgshapiro Messages which are undeliverable due to temporary address failures 366164562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 366264562Sgshapiro set. Contributed by Exactis.com, Inc. 366364562Sgshapiro New command line option '-L tag' which sets the identifier used for 366464562Sgshapiro syslog. Contributed by Exactis.com, Inc. 366564562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 366664562Sgshapiro avoids opening and reading each queue file when preparing 366764562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 366864562Sgshapiro Shared memory counters and microtimers functionality has been 366964562Sgshapiro donated by Exactis.com, Inc. 367064562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 367164562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 367264562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 367364562Sgshapiro being added. Suggested by Michael K. Sanders. 367464562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 367564562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 367664562Sgshapiro and John Beck of Sun Microsystems. 367764562Sgshapiro In low-disk space situations, where sendmail would previously refuse 367864562Sgshapiro connections, still accept them, but only allow ETRN commands. 367964562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 368064562Sgshapiro Ltd. 368164562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 368264562Sgshapiro on systems which support them. This can be used with LMTP 368364562Sgshapiro local delivery agents which listen on a named socket. An 368464562Sgshapiro example mailer might be: 368564562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 368664562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 368764562Sgshapiro A=FILE /var/run/lmtpd 368864562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 368964562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 369064562Sgshapiro instead. 369164562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 369264562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 369364562Sgshapiro connections), IPC (which will be deprecated in a future 369464562Sgshapiro version), and FILE (for UNIX domain socket delivery). 369564562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 369664562Sgshapiro flags. 369764562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 369864562Sgshapiro body of the original message on delivery status 369964562Sgshapiro notifications. 370064562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 370164562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 370264562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 370364562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 370464562Sgshapiro Steve Schweinhart of America Online. 370564562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 370664562Sgshapiro not be set after rulesets are defined. Suggested by 370764562Sgshapiro Mitchell Blank Jr of Exec-PC. 370864562Sgshapiro Do not report temporary failure on delivery to files. In 370964562Sgshapiro interactive delivery mode, this would result in two SMTP 371064562Sgshapiro responses after the DATA command. Problem noted by 371164562Sgshapiro Nik Conwell of Boston University. 371264562Sgshapiro Check file close when mailing to files. Problem noted by Nik 371364562Sgshapiro Conwell of Boston University. 371464562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 371564562Sgshapiro Curtis W. Hillegas of Princeton University. 371664562Sgshapiro Always bind to the LDAP server regardless of whether you are using 371764562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 371864562Sgshapiro @Home Network. 371964562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 372064562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 372164562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 372264562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 372364562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 372464562Sgshapiro similar to check_rcpt etc. 372564562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 372664562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 372764562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 372864562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 372964562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 373064562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 373164562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 373264562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 373364562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 373464562Sgshapiro the corresponding DSN parameter values. Proposed by 373564562Sgshapiro Mathias Herberts. 373664562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 373764562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 373864562Sgshapiro before the message has been collected, thereafter it holds 373964562Sgshapiro the message size as computed by sendmail (and can be used 374064562Sgshapiro in check_compat). 374164562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 374264562Sgshapiro sendmail is using instead of the value of the DeliveryMode 374364562Sgshapiro option. 374464562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 374564562Sgshapiro Drop explicit From: if same as what would be generated only if it is 374664562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 374764562Sgshapiro Write pid to file also if sendmail only processes the queue. 374864562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 374964562Sgshapiro Log "low on disk space" only when necessary. 375064562Sgshapiro New macro ${load_avg} can be used to check the current load average. 375164562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 375264562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 375364562Sgshapiro is set. 375464562Sgshapiro Flag -S for maps to specify the character which is substituted 375564562Sgshapiro for spaces (instead of the default given by O BlankSub). 375664562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 375764562Sgshapiro This flag is set by default for the host map. Based on a 375864562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 375964562Sgshapiro Open maps only on demand, not at startup. 376064562Sgshapiro Log warning about unsupported IP address families. 376164562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 376264562Sgshapiro of the sum of all headers. This can be used to prevent 376364562Sgshapiro a denial-of-service attack. 376464562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 376564562Sgshapiro headers and parameters within those headers. This option 376664562Sgshapiro is intended to protect mail user agents from buffer 376764562Sgshapiro overflow attacks. 376864562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 376964562Sgshapiro alias recursion. 377064562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 377164562Sgshapiro Map type syslog to log the key via syslogd. 377264562Sgshapiro Entries in the alias file can be continued by putting a backslash 377364562Sgshapiro directly before the newline. 377464562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 377564562Sgshapiro dead.letter file, formerly hardcoded to 377664562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 377764562Sgshapiro default), sendmail will not attempt to save to a 377864562Sgshapiro system-wide dead.letter file if it can not bounce the mail 377964562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 378064562Sgshapiro file as it has in the past when the dead.letter file 378164562Sgshapiro could not be opened. 378264562Sgshapiro New option PidFile to define the location of the pid file. The 378364562Sgshapiro value of this option is macro expanded. 378464562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 378564562Sgshapiro process title shown in 'ps' listings. 378664562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 378764562Sgshapiro (along with the already existing macros): 378864562Sgshapiro ${daemon_info} Daemon information, e.g. 378964562Sgshapiro SMTP+queueing@00:30:00 379064562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 379164562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 379264562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 379364562Sgshapiro ${daemon_port} Daemon port, e.g., 25 379464562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 379564562Sgshapiro New macros especially for virtual hosting: 379664562Sgshapiro ${if_name} hostname of interface of incoming connection. 379764562Sgshapiro ${if_addr} address of interface of incoming connection. 379864562Sgshapiro The latter is only set if the interface does not belong to the 379964562Sgshapiro loopback net. 380064562Sgshapiro If a message being accepted via a method other than SMTP and 380164562Sgshapiro would be rejected by a header check, do not send the message. 380264562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 380364562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 380464562Sgshapiro Provide header value as quoted string in the macro 380564562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 380664562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 380764562Sgshapiro The length of the header value is stored in ${hdrlen}. 380864562Sgshapiro H*: allows to specify a default ruleset for header checks. This 380964562Sgshapiro ruleset will only be called if the individual header does 381064562Sgshapiro not have its own ruleset assigned. Suggested by Jan 381164562Sgshapiro Krueger of Unix-AG of University of Hannover. 381264562Sgshapiro The name of the header field stored in ${hdr_name}. 381364562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 381464562Sgshapiro removed if the config file version is greater than or equal 381564562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 381664562Sgshapiro input "token (1)" but does not match "token". 381764562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 381864562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 381964562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 382064562Sgshapiro Ericsson. 382164562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 382264562Sgshapiro messages with 8-bit text in headers. Problem noted by 382364562Sgshapiro Per Steinar Iversen of Oslo College. Fix from Per Hedeland 382464562Sgshapiro of Ericsson. 382564562Sgshapiro Avoid keeping maps locked longer than necessary when re-opening a 382664562Sgshapiro modified database map file. Problem noted by Chris Adams 382764562Sgshapiro of Renaissance Internet Services. 382864562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 382964562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 383064562Sgshapiro queue up the message instead of bouncing it. 383164562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 383264562Sgshapiro standard does not provide any indication of what to do when 383364562Sgshapiro something other than 250 is received. Based on a patch 383464562Sgshapiro from Steve Schweinhart of America Online. 383564562Sgshapiro New option TrustedUser allows to specify a user who can own 383664562Sgshapiro important files instead of root. This requires HASFCHOWN. 383764562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 383864562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 383964562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 384064562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 384164562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 384264562Sgshapiro $? tests also whether the macro is non-null. 384364562Sgshapiro Print an error message if a mailer definition contains an invalid 384464562Sgshapiro equate name. 384564562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 384664562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 384764562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 384864562Sgshapiro mailer to return after sending all data to it. 384964562Sgshapiro Only free memory from the process list when adding a new process 385064562Sgshapiro into a previously filled slot. Previously, the memory was 385164562Sgshapiro freed at removal time. Since removal can happen in a 385264562Sgshapiro signal handler, this may leave the memory map in an 385364562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 385464562Sgshapiro David Cooley of Colby College. 385564562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 385664562Sgshapiro local users in the passwd file. The UserDB code has 385764562Sgshapiro already decided the message will be passed to another host 385864562Sgshapiro for processing. Fix from Tony Landells of Burdett 385964562Sgshapiro Buckeridge Young Limited. 386064562Sgshapiro Support LDAP authorization via either a file containing the 386164562Sgshapiro password or Kerberos V4 using the new map options 386264562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 386364562Sgshapiro distinguished_name is who to login as. The method can be 386464562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 386564562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 386664562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 386764562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 386864562Sgshapiro of Stanford University. 386964562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 387064562Sgshapiro deprecated and will be removed in a future version. 387164562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 387264562Sgshapiro and the map has the column delimiter set, it turns that 387364562Sgshapiro response into a delimiter separated string. The LDAP map 387464562Sgshapiro will traverse multiple entries as well. LDAP alias maps 387564562Sgshapiro automatically set the column delimiter to the comma. 387664562Sgshapiro Based on patch from Booker Bense of Stanford University and 387764562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 387864562Sgshapiro Support return of multiple values for a single LDAP lookup. The 387964562Sgshapiro values to be returned should be in a comma separated string. 388064562Sgshapiro For example, `-v "email,emailother"'. Patch from 388164562Sgshapiro Curtis W. Hillegas of Princeton University. 388264562Sgshapiro Allow the use of LDAP for alias maps. 388364562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 388464562Sgshapiro attributes found in the match will be returned. 388564562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 388664562Sgshapiro breaking up a single entry into multiple entries. This is 388764562Sgshapiro needed for LDAP alias file specifications to allow for 388864562Sgshapiro comma separated key and value strings. 388964562Sgshapiro Keep connections to LDAP server open instead of opening and closing 389064562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 389164562Sgshapiro connections such that multiple maps which use the same 389264562Sgshapiro host, port, bind DN, and authentication will only result in 389364562Sgshapiro a single connection to that host. 389464562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 389564562Sgshapiro Be more careful about checking for errors and freeing memory on 389664562Sgshapiro LDAP lookups. 389764562Sgshapiro Use asynchronous LDAP searches to save memory and network 389864562Sgshapiro resources. 389964562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 390064562Sgshapiro Increase portability to the Netscape LDAP libraries. 390164562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 390264562Sgshapiro replaced with the literal contents of the map lookup key -- 390364562Sgshapiro note that this means a lookup can be done using the LDAP 390464562Sgshapiro special characters. The new '%0' token can be used instead 390564562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 390664562Sgshapiro For example, if the LDAP map specification contains '-k 390764562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 390864562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 390964562Sgshapiro user attribute. Instead, if the LDAP map specification 391064562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 391164562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 391264562Sgshapiro with the name "*". 391364562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 391464562Sgshapiro more than one is returned, it is equivalent to no records 391564562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 391664562Sgshapiro alias dereference option; "-Z size" limits the number of 391764562Sgshapiro matches to return. 391864562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 391964562Sgshapiro LDAP maps. The value should only contain LDAP specific 392064562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 392164562Sgshapiro settings will be used for all LDAP maps unless they are 392264562Sgshapiro specified in the individual map specification ('K' 392364562Sgshapiro command). This option should be set before any LDAP maps 392464562Sgshapiro are defined. 392564562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 392664562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 392764562Sgshapiro Tech. 392864562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 392964562Sgshapiro particular, class entries get much smaller, which can be 393064562Sgshapiro important if you have large classes. 393164562Sgshapiro On network-related temporary failures, record the hostname which 393264562Sgshapiro gave error in the queued status message. Requested by 393364562Sgshapiro Ulrich Windl of the Universitat Regensburg. 393464562Sgshapiro Add new F=% mailer flag to allow for a store and forward 393564562Sgshapiro configuration. Mailers which have this flag will not attempt 393671345Sgshapiro delivery on initial receipt of a message or on queue runs 393764562Sgshapiro unless the queued message is selected using one of the 393864562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 393964562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 394064562Sgshapiro New option ControlSocketName which, when set, creates a daemon 394164562Sgshapiro control socket. This socket allows an external program to 394264562Sgshapiro control and query status from the running sendmail daemon 394364562Sgshapiro via a named socket, similar to the ctlinnd interface to the 394464562Sgshapiro INN news server. Access to this interface is controlled by 394564562Sgshapiro the UNIX file permissions on the named socket on most UNIX 394664562Sgshapiro systems (see sendmail/README for more information). An 394764562Sgshapiro example control program is provided as contrib/smcontrol.pl. 394864562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 394964562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 395064562Sgshapiro number of processors online on the system (if that can be 395164562Sgshapiro determined). For single processor machines, this change 395264562Sgshapiro has no effect. 395364562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 395464562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 395564562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 395664562Sgshapiro Motonori Nakamura of Kyoto University. 395764562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 395864562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 395964562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 396064562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 396164562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 396264562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 396364562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 396464562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 396564562Sgshapiro connection-based denial of service attacks. 396664562Sgshapiro Log basic information about authenticated connections at LogLevel 396764562Sgshapiro 10 or higher. 396864562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 396964562Sgshapiro information (from= syslog line). 397064562Sgshapiro Log the DSN code for each recipient if one is available as a new 397164562Sgshapiro equate (dsn=). 397264562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 3973120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 3974120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 3975120256Sgshapiro of the University of Illinois at Urbana-Champaign. 397664562Sgshapiro Detect temporary lookup failures in the host map if looking up a 397764562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 397864562Sgshapiro Finnish Meteorological Institute. 397964562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 398064562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 398164562Sgshapiro When a forward file points to an alias which runs a program, run 398264562Sgshapiro the program as the default user and the default group, not 398364562Sgshapiro the forward file user. This change also assures the 398464562Sgshapiro :include: directives in aliases are also processed using 398564562Sgshapiro the default user and group. Problem noted by Sergiu 398664562Sgshapiro Popovici of DNT Romania. 398764562Sgshapiro Prevent attempts to save a dead.letter file for a user with 398864562Sgshapiro no home directory (/no/such/directory). Problem noted by 398964562Sgshapiro Michael Brown of Finnigan FT/MS. 399064562Sgshapiro Include message delay and number of tries when logging that a 399164562Sgshapiro message has been completely delivered (LogLevel of 10 or 399264562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 399364562Sgshapiro Log the sender of a message even if none of the recipients were 399464562Sgshapiro accepted. If some of the recipients were rejected, it is 399564562Sgshapiro helpful to know the sender of the message. 399664562Sgshapiro Check the root directory (/) when checking a path for safety. 399764562Sgshapiro Problem noted by John Beck of Sun Microsystems. 399864562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 399964562Sgshapiro interactive and delivering to an alias which resolves to 400064562Sgshapiro multiple files. 400164562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 400264562Sgshapiro greater (see below); the help function doesn't print the 400364562Sgshapiro version of sendmail any longer, instead it is placed in 400464562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 400564562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 400664562Sgshapiro skipped and a version line (#vers) is introduced. The 400764562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 400864562Sgshapiro version is found, a warning is logged. The '#vers' 400964562Sgshapiro directive should be placed at the top of the help file. 401064562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 401164562Sgshapiro disk succeeded. Suggested by Nick Christenson. 401264562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 401364562Sgshapiro length before the attempt. 401464562Sgshapiro If a forward points to a filename for delivery, change to the 401564562Sgshapiro user's uid before checking permissions on the file. This 401664562Sgshapiro allows delivery to files on NFS mounted directories where 401764562Sgshapiro root is remapped to nobody. Problem noted by Harald 401864562Sgshapiro Daeubler of Universitaet Ulm. 401964562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 402064562Sgshapiro host status files, not all files. 402164562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 402264562Sgshapiro in the queue file for the message and set when delivery 402364562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 402464562Sgshapiro Wonderworks Inc. 402564562Sgshapiro Add support for storing information between rulesets using the new 402664562Sgshapiro macro map class. This can be used to store information 402764562Sgshapiro between queue runs as well using $={persistentMacros}. 402864562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 402964562Sgshapiro of Hannover. 403064562Sgshapiro New map class arith to allow for computations in rules. The 403164562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 403264562Sgshapiro as key. The two operands are specified as arguments; the 403364562Sgshapiro lookup returns the result of the computation. For example, 403464562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 403564562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 403664562Sgshapiro Add new syntax for header declarations which decide whether to 403764562Sgshapiro include the header based on a macro rather than a mailer 403864562Sgshapiro flag: 403964562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 404064562Sgshapiro This should be used along with $={persistentMacros}. 404164562Sgshapiro It can be used for adding headers to a message based on 404264562Sgshapiro the results of check_* and header check rulesets. 404364562Sgshapiro Allow new named config file rule check_eoh which is called after 404464562Sgshapiro all of the headers have been collected. The input to the 404564562Sgshapiro ruleset the number of headers and the size of all of the 404664562Sgshapiro headers in bytes separated by $|. This ruleset along with 404764562Sgshapiro the macro storage map can be used to correlate information 404864562Sgshapiro gathered between headers and to check for missing headers. 404964562Sgshapiro See cf/README or doc/op/op.ps for an example. 405064562Sgshapiro Change the default for the MeToo option to True to correspond 405164562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 405264562Sgshapiro option is deprecated and will be removed from a future 405364562Sgshapiro version. 405464562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 405564562Sgshapiro Change the sendmail binary default for SuperSafe to True. 405664562Sgshapiro Display ruleset names in debug and address test mode output 405764562Sgshapiro if referencing a named ruleset. 405864562Sgshapiro New mailer equate m= which will limit the number of messages 405964562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 406064562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 406164562Sgshapiro using it to sort. Now all the same domains are really run 406264562Sgshapiro through the queue together. If they have the same MX host, 406364562Sgshapiro then they will have a much better opportunity to use the 406464562Sgshapiro connection cache if available. This should be a reasonable 406564562Sgshapiro performance improvement. Patch from Randall Winchester of 406664562Sgshapiro the University of Maryland. 406764562Sgshapiro If a message is rejected by a header check ruleset, log who would 406864562Sgshapiro have received the message if it had not been rejected. 406964562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 407064562Sgshapiro queue immediately. No delivery attempt is made. 407164562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 407264562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 407364562Sgshapiro COMMANDS). 407464562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 407564562Sgshapiro but for outgoing connections. 407664562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 407764562Sgshapiro error messages and logging) and Modifiers, i.e. 407864562Sgshapiro a require authentication 407964562Sgshapiro b bind to interface through which mail has 408064562Sgshapiro been received 408164562Sgshapiro c perform hostname canonification 408264562Sgshapiro f require fully qualified hostname 408364562Sgshapiro h use name of interface for outgoing HELO 408464562Sgshapiro command 408564562Sgshapiro C don't perform hostname canonification 408664562Sgshapiro E disallow ETRN (see RFC 2476) 408764562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 408864562Sgshapiro h use name of interface for HELO command 408964562Sgshapiro The version number for queue files (qf) has been incremented to 4. 409064562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 409164562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 409264562Sgshapiro Institutes of Health. 409364562Sgshapiro If a mailer dies, print the status in decimal instead of octal 409464562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 409564562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 409664562Sgshapiro Move message priority from sender to recipient logging. Suggested by 409764562Sgshapiro Ulrich Windl of the Universitat Regensburg. 409864562Sgshapiro Add support for Berkeley DB 3.X. 409964562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 410064562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 410164562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 410264562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 410364562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 410464562Sgshapiro sub-options is set on the command line. Problem noted by 410564562Sgshapiro Graeme Hewson of Oracle. 410664562Sgshapiro Randomize equal preference MX records each time delivery is 410764562Sgshapiro attempted via a new connection to a host instead of once per 410864562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 410964562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 411064562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 411164562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 411264562Sgshapiro to hosts which have dynamically assigned names. 411364562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 411464562Sgshapiro the bounce for the same reason. If the body is not 8-bit 411564562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 411664562Sgshapiro not be included in the bounce. Problem noted by Valdis 411764562Sgshapiro Kletnieks of Virginia Tech. 411864562Sgshapiro The timeout for sending a message via SMTP has been changed from 411964562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 412064562Sgshapiro simply checks for progress on sending data every 5 minutes. 412164562Sgshapiro This will detect the inability to send information quicker 412264562Sgshapiro and reduce the number of processes simply waiting to 412364562Sgshapiro timeout. 412464562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 412564562Sgshapiro interface address structure when loading the system network 412664562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 412764562Sgshapiro Nanoteq. 412864562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 412964562Sgshapiro indicates the number of interfaces to read when probing 413064562Sgshapiro for hostnames and IP addresses for class w ($=w). The 413164562Sgshapiro default value is 512. Based on idea from Reinier 413264562Sgshapiro Bezuidenhout of Nanoteq. 413364562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 413464562Sgshapiro on load average. 413564562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 413664562Sgshapiro Northern Illinois University. 413764562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 413864562Sgshapiro envelope splitting has occurred. 413964562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 414064562Sgshapiro Luke Mewburn from RMIT University. 414164562Sgshapiro Add a "/quit" command to address test mode. 414264562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 414364562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 414464562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 414564562Sgshapiro Institute. 414664562Sgshapiro The contents of a class can now be copied to another class using 414764562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 414864562Sgshapiro the items in class $={Source} into the class $={Dest}. 414964562Sgshapiro Include original envelope's error transcript in bounces created for 415064562Sgshapiro split (owner-) envelopes to see the original errors when 415164562Sgshapiro the recipients were added. Based on fix from Motonori 415264562Sgshapiro Nakamura of Kyoto University. 415364562Sgshapiro Show reason for permanent delivery errors directly after the 415464562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 415564562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 415664562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 415764562Sgshapiro If the specification for the queue run interval (-q###) has a 415864562Sgshapiro syntax error, consider the error fatal and exit. 415964562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 416064562Sgshapiro noted by Motonori Nakamura of Kyoto University. 416164562Sgshapiro On operating systems which have setlogin(2), use it to set the 416264562Sgshapiro login name to the RunAsUserName when starting as a daemon. 416364562Sgshapiro This is for delivery to programs which use getlogin(). 416464562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 416564562Sgshapiro Differentiate between "command not implemented" and "command 416664562Sgshapiro unrecognized" in the SMTP dialogue. 416764562Sgshapiro Strip returns from forward and include files. Problem noted by 416864562Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 416964562Sgshapiro Prevent a core dump when using 'sendmail -bv' on an address which 417064562Sgshapiro resolves to the $#error mailer with a temporary failure. 417164562Sgshapiro Based on fix from Neil Rickert of Northern Illinois 417264562Sgshapiro University. 417364562Sgshapiro Prevent multiple deliveries of a message with a "non-local alias" 417464562Sgshapiro pointing to a local user, if canonicalization fails 417564562Sgshapiro the message was requeued *and* delivered to the alias. 417664562Sgshapiro If an invalid ruleset is declared, the ruleset name could be 417764562Sgshapiro ignored and its rules added to S0. Instead, ignore the 417864562Sgshapiro ruleset lines as well. 417964562Sgshapiro Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient 418064562Sgshapiro success DSN fields as well as duplicate entries for a 418164562Sgshapiro single address due to S5 and UserDB processing. Problems 418264562Sgshapiro noted by Kari Hurtta of the Finnish Meteorological 418364562Sgshapiro Institute. 418464562Sgshapiro Turn off timeouts when exiting sendmail due to an interrupt signal 418564562Sgshapiro to prevent the timeout from firing during the exit process. 418664562Sgshapiro Problem noted by Michael Shapiro of Sun Microsystems. 418764562Sgshapiro Do not append @MyHostName to non-RFC822 addresses output by the EXPN 418864562Sgshapiro command or on Final-Recipient: and X-Actual-Recipient: DSN 418964562Sgshapiro headers. Non-RFC822 addresses include deliveries to 419064562Sgshapiro programs, file, DECnet, etc. 419164562Sgshapiro Fix logic for determining if a local user is using -f or -bs to 419264562Sgshapiro spoof their return address. Based on idea from Neil Rickert 419364562Sgshapiro of Northern Illinois University and patch from Per Hedeland 419464562Sgshapiro of Ericsson. 419564562Sgshapiro Report the proper UID in the bounce message if an :include: file is 419664562Sgshapiro owned by a uid that doesn't map to a username and the 419764562Sgshapiro :include: file contains delivery to a file or program. 419864562Sgshapiro Problem noted by John Beck of Sun Microsystems. 419964562Sgshapiro Avoid the attempt of trying to send a second SMTP QUIT command if 420064562Sgshapiro the remote server responds to the first QUIT with a 4xx 420164562Sgshapiro response code and drops the connection. This behavior was 420264562Sgshapiro noted by Ulrich Windl of the Universitat Regensburg when 420364562Sgshapiro sendmail was talking to the Mercury 1.43 MTA. 420464562Sgshapiro If a hostname lookup times out and ServiceSwitchFile is set but the 420564562Sgshapiro file is not present, the lookup failure would be marked as 420664562Sgshapiro a permanent failure instead of a temporary failure. Fix 420764562Sgshapiro from Russell King of the ARM Linux Project. 420864562Sgshapiro Handle aliases or forwards which deliver to programs using tabs 420964562Sgshapiro instead of spaces between arguments.

Problem noted by Juergen Georgi of RUS University 422264562Sgshapiro of Stuttgart and Kyle Tucker of Parexel International. 422364562Sgshapiro Prevent +detail information from interfering with local delivery to 422464562Sgshapiro multiple users in the same transaction (F=m). 422564562Sgshapiro Add H_FORCE flag for the X-Authentication-Warning: header, so it 422664562Sgshapiro will be added even if one already exists. Problem noted 422764562Sgshapiro by Michal Zalewski of Marchew Industries. 422864562Sgshapiro Stop processing SMTP commands if the SMTP connection is dropped. 422964562Sgshapiro This prevents a remote system from flooding the connection 423064562Sgshapiro with commands and then disconnecting. Previously, the 423164562Sgshapiro server would process all of the buffered commands.

Problem 423464562Sgshapiro noted by Michal Zalewski of Marchew Industries. 423564562Sgshapiro If multiple header checks resolve to the $#error mailer, use the 423664562Sgshapiro last permanent (5XX) failure if any exist. Otherwise, use 423764562Sgshapiro the last temporary (4XX) failure. 423864562Sgshapiro RFC 1891 requires "hexchar" in a "xtext" to be upper case. Patch 423964562Sgshapiro from Ronald F. Guilmette of Infinite Monkeys & Co. 424064562Sgshapiro Timeout.ident now defaults to 5 seconds instead of 30 seconds to 424164562Sgshapiro prevent the now common delays associated with mailing to a 424264562Sgshapiro site which drops IDENT packets. Suggested by many. 424364562Sgshapiro Persistent host status data is not reloaded disk when current data 424464562Sgshapiro is available in the in-memory cache. Problem noted by Per 424564562Sgshapiro Hedeland of Ericsson. 424664562Sgshapiro mailq displays unprintable characters in addresses as their octal 424764562Sgshapiro representation and a leading backslash. This avoids problems 424864562Sgshapiro with "unprintable" characters. Problem noted by Michal 424964562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 425064562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 425164562Sgshapiro one character past the limit. This would cause subsequent 425264562Sgshapiro hops to break the line again. The '!' is now placed in 425364562Sgshapiro the last column of the limit if the line needs to be broken. 425464562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises. Based on fix 425564562Sgshapiro from Per Hedeland of Ericsson. 425664562Sgshapiro If a resolver ANY query is larger than the UDP packet size, the 425764562Sgshapiro resolver will fall back to TCP.

Panepucci of 456564562Sgshapiro Yale University. 456664562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 456764562Sgshapiro be used for building. 456864562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 456964562Sgshapiro used for a fresh build. 457064562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 457164562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 457264562Sgshapiro ranlib. 457364562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 457464562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 457564562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 457664562Sgshapiro building of the man pages when defined. Suggested by Bryan 457764562Sgshapiro Costales. 457864562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 457964562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 458064562Sgshapiro installation of the sendmail helpfile and statistics file 458164562Sgshapiro respectively. Suggested by Bryan Costales. 458264562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 458364562Sgshapiro of Siemens Business Services. 458464562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 458564562Sgshapiro stdio library. The new buffered file I/O depends on the 458664562Sgshapiro Torek stdio library. This option can be either portable or 458764562Sgshapiro torek. 458864562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 458964562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 459064562Sgshapiro They should contain the C source files for the object files 459164562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 459264562Sgshapiro will be passed to the 'make depend' stage of compilation. 459364562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 459464562Sgshapiro in the sendmail distribution. Each has the form 459564562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 459664562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 459764562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 459864562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 459964562Sgshapiro building the distribution, but documentation on the changes 460064562Sgshapiro are in devtools/README. 460164562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 460264562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 460364562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 460464562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 460564562Sgshapiro new variable which identifies the root of the source 460664562Sgshapiro directories for all of the programs in the distribution. 460764562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 460864562Sgshapiro time. They can both still be overridden by setting the m4 460964562Sgshapiro macro. 461064562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 461164562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 461264562Sgshapiro build configurations, and places objects in obj.prefix.*/. 461364562Sgshapiro Complains as 'Build -f file' does for existing object 461464562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 461564562Sgshapiro Corporation. 461664562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 461764562Sgshapiro manual pages in the directory tree specified by 461864562Sgshapiro confMANROOTMAN. 461964562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 462064562Sgshapiro preformatted pages from the distribution. The new variable 462164562Sgshapiro confCOPY specifies the copying program. 462264562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 462364562Sgshapiro question. Suggested by Terry Lambert of Whistle 462464562Sgshapiro Communications. 462564562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 462664562Sgshapiro of the installed statistics and help files, respectively. 462764562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 462864562Sgshapiro operating system identity. Problem noted by Erik 462964562Sgshapiro Wachtenheim of Dartmouth College. 463064562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 463164562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 463264562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 463364562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 463464562Sgshapiro how to strip binaries. These are used by the new 463564562Sgshapiro install-strip target. 463664562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 463764562Sgshapiro the others (if it exists). 463864562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 463964562Sgshapiro then the default ones. 464090792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 464164562Sgshapiro as local delivery agent without LMTP mode, use 464264562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 464364562Sgshapiro to set the S flag. 464464562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 464564562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 464664562Sgshapiro Northern Illinois University. 464764562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 464864562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 464964562Sgshapiro the Finnish Meteorological Institute. 465064562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 465164562Sgshapiro MAILLOCK when compiling. Also requires linking with 465264562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 465364562Sgshapiro University. 465464562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 465564562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 465664562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 465764562Sgshapiro University. 465864562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 465964562Sgshapiro structure to the beginning of the program. This ensures that 466064562Sgshapiro the getservbyname() is done before any seteuid to a possibly 466164562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 466264562Sgshapiro on a Solaris system, this avoids syslog messages such as, 466364562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 466464562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 466564562Sgshapiro University. 466664562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 466764562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 466864562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 466964562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 467064562Sgshapiro characters (in LMTP mode), mail.local split the incoming 467164562Sgshapiro line up into 2046-character output lines (excluding the 467264562Sgshapiro newline). If an input line was 2047 characters long 467364562Sgshapiro (excluding CR-LF) and the last character was a '.', 467464562Sgshapiro mail.local saw it as the end of input, transfered it to the 467564562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 467664562Sgshapiro If the message was much longer, both sendmail and 467764562Sgshapiro mail.local would deadlock waiting for each other to read 467864562Sgshapiro what they have written. Problem noted by Peter Jeremy of 467964562Sgshapiro Alcatel Australia Limited. 468064562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 468164562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 468264562Sgshapiro Neil Rickert of Northern Illinois University. 468364562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 468464562Sgshapiro timeout to avoid starvation. 468564562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 468664562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 468764562Sgshapiro Infinite Monkeys & Co. 468864562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 468964562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 469064562Sgshapiro printed in a machine readable fashion and the stats file 469164562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 469264562Sgshapiro of Maryland. 469364562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 469464562Sgshapiro generated maps to the TrustedUser as specified in the 469564562Sgshapiro sendmail configuration file. 469664562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 469764562Sgshapiro configuration file to use for finding the TrustedUser 469864562Sgshapiro option. 469964562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 470064562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 470164562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 470264562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 470364562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 470464562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 470564562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 470664562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 470764562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 470864562Sgshapiro Corporation UK. 470964562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 471064562Sgshapiro (e.g., sendmail would not drop root privileges if the 471164562Sgshapiro option was specified on the command line). Problem noted 471264562Sgshapiro by Todd C. Miller of Courtesan Consulting. 471364562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 471464562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 471564562Sgshapiro Institute for Global Communications. 471664562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 471764562Sgshapiro alias file(s) if the -f option is not used. Patch from 471864562Sgshapiro John Beck of Sun Microsystems. 471964562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 472064562Sgshapiro configuration file to use for finding alias file(s). Patch 472164562Sgshapiro from John Beck of Sun Microsystems. 472264562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 472364562Sgshapiro lists using || and &&. Based on patch from Brian J. Coan 472464562Sgshapiro of the Institute for Global Communications. 472564562Sgshapiro SMRSH: Update README for the new Build system. From Tim Pierce 472664562Sgshapiro of RootsWeb Genealogical Data Cooperative. 472764562Sgshapiro VACATION: Added vacation auto-responder to sendmail distribution. 472864562Sgshapiro LIBSMDB: Added abstracted database library. Works with Berkeley 472964562Sgshapiro DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM. 473064562Sgshapiro Changed Files: 473164562Sgshapiro The Build script in the various program subdirectories are 473264562Sgshapiro no longer symbolic links. They are now scripts 473364562Sgshapiro which execute the actual Build script in 473464562Sgshapiro devtools/bin. 473564562Sgshapiro All the manual pages are now written against -man and not 473664562Sgshapiro -mandoc as they were previously. 473764562Sgshapiro Add a simple Makefile to every directory so make instead 473864562Sgshapiro of Build will work (unless parameters are 473964562Sgshapiro required for Build). 474064562Sgshapiro New Directories: 474164562Sgshapiro devtools/M4/UNIX 474264562Sgshapiro include 474364562Sgshapiro libmilter 474464562Sgshapiro libsmdb 474564562Sgshapiro libsmutil 474664562Sgshapiro vacation 474764562Sgshapiro Renamed Directories: 474864562Sgshapiro BuildTools => devtools 474964562Sgshapiro src => sendmail 475064562Sgshapiro Deleted Files: 475164562Sgshapiro cf/m4/nullrelay.m4 475264562Sgshapiro devtools/OS/Linux.ppc 475364562Sgshapiro devtools/OS/ReliantUNIX 475464562Sgshapiro devtools/OS/SINIX 475564562Sgshapiro sendmail/ldap_map.h 475664562Sgshapiro New Files: 475764562Sgshapiro INSTALL 475864562Sgshapiro PGPKEYS 475964562Sgshapiro cf/cf/generic-linux.cf 476064562Sgshapiro cf/cf/generic-linux.mc 476164562Sgshapiro cf/feature/delay_checks.m4 476264562Sgshapiro cf/feature/dnsbl.m4 476364562Sgshapiro cf/feature/generics_entire_domain.m4 476464562Sgshapiro cf/feature/no_default_msa.m4 476564562Sgshapiro cf/feature/relay_mail_from.m4 476664562Sgshapiro cf/feature/virtuser_entire_domain.m4 476764562Sgshapiro cf/mailer/qpage.m4 476864562Sgshapiro cf/ostype/bsdi.m4 476964562Sgshapiro cf/ostype/hpux11.m4 477064562Sgshapiro cf/ostype/openbsd.m4 477164562Sgshapiro contrib/bounce-resender.pl 477264562Sgshapiro contrib/domainmap.m4 477364562Sgshapiro contrib/qtool.8 477464562Sgshapiro contrib/qtool.pl 477564562Sgshapiro devtools/M4/depend/AIX.m4 477664562Sgshapiro devtools/M4/list.m4 477764562Sgshapiro devtools/M4/string.m4 477864562Sgshapiro devtools/M4/subst_ext.m4 477964562Sgshapiro devtools/M4/switch.m4 478064562Sgshapiro devtools/OS/Darwin 478164562Sgshapiro devtools/OS/GNU 478264562Sgshapiro devtools/OS/SINIX.5.43 478364562Sgshapiro devtools/OS/SINIX.5.44 478464562Sgshapiro devtools/OS/m88k 478564562Sgshapiro devtools/bin/find_in_path.sh 478664562Sgshapiro mail.local/Makefile 478764562Sgshapiro mailstats/Makefile 478864562Sgshapiro makemap/Makefile 478964562Sgshapiro praliases/Makefile 479064562Sgshapiro rmail/Makefile 479164562Sgshapiro sendmail/Makefile 479264562Sgshapiro sendmail/bf.h 479364562Sgshapiro sendmail/bf_portable.c 479464562Sgshapiro sendmail/bf_portable.h 479564562Sgshapiro sendmail/bf_torek.c 479664562Sgshapiro sendmail/bf_torek.h 479764562Sgshapiro sendmail/shmticklib.c 479864562Sgshapiro sendmail/statusd_shm.h 479964562Sgshapiro sendmail/timers.c 480064562Sgshapiro sendmail/timers.h 480164562Sgshapiro smrsh/Makefile 480264562Sgshapiro vacation/Makefile 480364562Sgshapiro Renamed Files: 480464562Sgshapiro cf/ostype/gnuhurd.m4 => cf/ostype/gnu.m4 480564562Sgshapiro sendmail/cdefs.h => include/sendmail/cdefs.h 480664562Sgshapiro sendmail/sendmail.hf => sendmail/helpfile 480764562Sgshapiro sendmail/mailstats.h => include/sendmail/mailstats.h 480864562Sgshapiro sendmail/pathnames.h => include/sendmail/pathnames.h 480964562Sgshapiro sendmail/safefile.c => libsmutil/safefile.c 481064562Sgshapiro sendmail/snprintf.c => libsmutil/snprintf.c 481164562Sgshapiro sendmail/useful.h => include/sendmail/useful.h 481264562Sgshapiro cf/ostype/solaris2.m4 => cf/ostype/solaris2.pre5.m4 481364562Sgshapiro Copied Files: 481464562Sgshapiro cf/ostype/solaris2.ml.m4 => cf/ostype/solaris2.m4 481564562Sgshapiro 481664562Sgshapiro8.9.3/8.9.3 1999/02/04 481743730Speter SECURITY: Limit message headers to a maximum of 32K bytes (total 481843730Speter of all headers in a single message) to prevent a denial of 481943730Speter service attack.

Problem 482943730Speter noted by Lars Hecking of University College, Cork, Ireland. 483043730Speter If ruleset 5 rewrote the local address to an :include: directive, 483143730Speter the delivery would fail with an "aliasing/forwarding loop 483243730Speter broken" error. Problem noted by Eric C Hagberg of Morgan 483343730Speter Stanley. Fix from Per Hedeland of Ericsson. 483443730Speter Allow -T to work for bestmx maps. Fix from Aaron Schrab of 483543730Speter ExecPC Internet Systems. 483643730Speter During the transfer of a message in an SMTP transaction, if a 483743730Speter TCP timeout occurs, the message would be properly queued 483843730Speter for later retry but the failure would be logged as 483943730Speter "Illegal Seek" instead of a timeout. Problem noted by 484043730Speter Piotr Kucharski of the Warsaw School of Economics (SGH) 484143730Speter and Carles Xavier Munyoz Baldo of CTV Internet. 484243730Speter Prevent multiple deliveries on a self-referencing alias if the 484343730Speter F=w mailer flag is not set. Problem noted by Murray S. 484443730Speter Kucherawy of Concentric Network Corporation and Per 484543730Speter Hedeland of Ericsson. 484643730Speter Do not strip empty headers but if there is no value and a 484743730Speter default is defined in sendmail.cf, use the default. 484843730Speter Problem noted by Philip Guenther of Gustavus Adolphus 484943730Speter College and Christopher McCrory of Netus, Inc. 485043730Speter Don't inherit information about the sender (notably the full name) 485143730Speter in SMTP (-bs) mode, since this might be called from inetd. 485243730Speter Accept any 3xx reply code in response to DATA command instead of 485343730Speter requiring 354. This change will match the wording to be 485443730Speter published in the updated SMTP specification from the DRUMS 485543730Speter group of the IETF. 485643730Speter Portability: 485764562Sgshapiro AIX 4.2.0 or 4.2.1 may become updated by the fileset 485864562Sgshapiro bos.rte.net level 4.2.0.2. This introduces the 485964562Sgshapiro softlink /usr/lib/libbind.a which should 486043730Speter not be used. It conflicts with the resolver 486143730Speter built into libc.a. "bind" has been removed 486243730Speter from the confLIBSEARCH BuildTools variable. 486343730Speter Users who have installed BIND 8.X will have 486443730Speter to add it back in their site.config.m4 file. 486543730Speter Problem noted by Ole Holm Nielsen of the 486643730Speter Technical University of Denmark. 486743730Speter CRAY TS 10.0.x from Sven Nielsen of San Diego 486843730Speter Supercomputer Center. 486943730Speter Improved LDAP version 3 integration based on input 487043730Speter from Kurt D.

Previously this was 522038032Speter only done if you had magic characters (0x81) to indicate 522138032Speter macro expansion. Now $x will be expanded. This means that 522238032Speter real dollar signs have to be backslash escaped. 522364562Sgshapiro TCP Wrappers expects "unknown" in the hostname argument if the 522438032Speter reverse DNS lookup for the incoming connection fails. 522538032Speter Problem noted by Randy Grimshaw of Syracuse University and 522638032Speter Wietse Venema of the Global Security Analysis Lab at 522738032Speter IBM T.J. Watson Research. 522838032Speter DSN success bounces generated from an invocation of sendmail -t 522938032Speter would be sent to both the sender and MAILER-DAEMON. 523038032Speter Problem noted by Claus Assmann of 523138032Speter Christian-Albrechts-University of Kiel. 523238032Speter Avoid "Error 0" messages on delivery mailers which exit with a 523338032Speter valid exit value such as EX_NOPERM. Fix from Andreas Luik 523438032Speter of ISA Informationssysteme GmbH. 523538032Speter Tokenize $&x expansions on right hand side of rules. This eliminates 523638032Speter the need to use tricks like $(dequote "" $&{client_name} $) 523738032Speter to cause the ${client_name} macro to be properly tokenized. 523838032Speter Add the MaxRecipientsPerMessage option: this limits the number of 523938032Speter recipients that will be accepted in a single SMTP 524038032Speter transaction. After this number is reached, sendmail 524138032Speter starts returning "452 Too many recipients" to all RCPT 524238032Speter commands. This can be used to limit the number of recipients 524338032Speter per envelope (in particular, to discourage use of the server 524438032Speter for spamming). Note: a better approach is to restrict 524538032Speter relaying entirely. 524638032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 524738032Speter to ldapx map and added timeout for ldap_open call to 524838032Speter avoid hanging sendmail in the event of hung LDAP servers. 524938032Speter Patch from Booker Bense of Stanford University. 525038032Speter Allow multiple -qI, -qR, or -qS queue run limiters. For example, 525138032Speter '-qRfoo -qRbar' would deliver mail to recipients with foo or 525238032Speter bar in their address. Patch from Allan E Johannesen of 525338032Speter Worcester Polytechnic Institute. 525438032Speter The bestmx map will now return a list of the MX servers for a host if 525538032Speter passed a column delimiter via the -z map flag. This can be 525638032Speter used to check if the server is an MX server for the recipient 525738032Speter of a message. This can be used to help prevent relaying. 525838032Speter Patch from Mitchell Blank Jr of Exec-PC. 525938032Speter Mark failures for the *file* mailer and return bounce messages to the 526038032Speter sender for those failures. 526138032Speter Prevent bogus syslog timestamps on errors in sendmail.cf by 526238032Speter preserving the TZ environment variable until TimeZoneSpec 526338032Speter has been determined. Problem noted by Ralf Hildebrandt of 526438032Speter Technical University of Braunschweig. Patch from Per Hedeland 526538032Speter of Ericsson. 526638032Speter Print test input in address test mode when input is not from the tty 526764562Sgshapiro when the -v flag is given (i.e., sendmail -bt -v) to make 526838032Speter output easier to decipher. Problem noted by Aidan Nichol 526938032Speter of Procter & Gamble. 527038032Speter The LDAP map -s flag was not properly parsed and the error message 527164562Sgshapiro given included the remainder of the arguments instead of 527238032Speter solely the argument in error. Problem noted by Aidan Nichol 527338032Speter of Procter & Gamble. 527438032Speter New DontBlameSendmail option. This option allows administrators to 527538032Speter bypass some of sendmail's file security checks at the expense 527638032Speter of system security. This should only be used if you are 527738032Speter absolutely sure you know the consequences. The available 527838032Speter DontBlameSendmail options are: 527938032Speter Safe 528038032Speter AssumeSafeChown 528138032Speter ClassFileInUnsafeDirPath 528238032Speter ErrorHeaderInUnsafeDirPath 528338032Speter GroupWritableDirPathSafe 528438032Speter GroupWritableForwardFileSafe 528538032Speter GroupWritableIncludeFileSafe 528638032Speter GroupWritableAliasFile 528738032Speter HelpFileinUnsafeDirPath 528838032Speter WorldWritableAliasFile 528938032Speter ForwardFileInGroupWritableDirPath 529038032Speter IncludeFileInGroupWritableDirPath 529138032Speter ForwardFileInUnsafeDirPath 529238032Speter IncludeFileInUnsafeDirPath 529338032Speter ForwardFileInUnsafeDirPathSafe 529438032Speter IncludeFileInUnsafeDirPathSafe 529538032Speter MapInUnsafeDirPath 529638032Speter LinkedAliasFileInWritableDir 529738032Speter LinkedClassFileInWritableDir 529838032Speter LinkedForwardFileInWritableDir 529938032Speter LinkedIncludeFileInWritableDir 530038032Speter LinkedMapInWritableDir 530138032Speter LinkedServiceSwitchFileInWritableDir 530238032Speter FileDeliveryToHardLink 530338032Speter FileDeliveryToSymLink 530438032Speter WriteMapToHardLink 530538032Speter WriteMapToSymLink 530638032Speter WriteStatsToHardLink 530738032Speter WriteStatsToSymLink 530838032Speter RunProgramInUnsafeDirPath 530938032Speter RunWritableProgram 531038032Speter New DontProbeInterfaces option to turn off the inclusion of all the 531138032Speter interface names in $=w on startup. In particular, if you 531238032Speter have lots of virtual interfaces, this option will speed up 531338032Speter startup. However, unless you make other arrangements, mail 531438032Speter sent to those addresses will be bounced. 531538032Speter Automatically create alias databases if they don't exist and 531638032Speter AutoRebuildAliases is set. 531738032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 531838032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 531938032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 532038032Speter When determining the client host name ($&{client_name} macro), do 532138032Speter a forward (A) DNS lookup on the result of the PTR lookup 532238032Speter and compare results. If they differ or if the PTR lookup 532338032Speter fails, &{client_name} will contain the IP address 532464562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 532538032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 532638032Speter (i.e, it is like -ax for the temporary failure case, in 532738032Speter contrast to the success case). 532838032Speter New syntax to do limited checking of header syntax. A config line 532938032Speter of the form: 533038032Speter HHeader: $>Ruleset 533138032Speter causes the indicated Ruleset to be invoked on the Header 533238032Speter when read. This ruleset works like the check_* rulesets -- 533338032Speter that is, it can reject mail on the basis of the contents. 533438032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 533538032Speter from hiding their connection information in Received: 533638032Speter headers. 533738032Speter When SingleThreadDelivery is active, deliveries to locked hosts 533838032Speter are skipped. This will cause the delivering process to 533938032Speter try the next MX host or queue the message if no other MX 534038032Speter hosts are available. Suggested by Alexander Litvin. 534138032Speter The [FILE] mailer type now delivers to the file specified in the 534238032Speter A= equate of the mailer definition instead of $u. It also 534338032Speter obeys all of the F= mailer flags such as the MIME 534438032Speter 7/8 bit conversion flags. This is useful for defining 534538032Speter a mailer which delivers to the same file regardless of the 534664562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 534738032Speter Do not assume the identity of a remote connection is root@localhost 534838032Speter if the remote connection closes the socket before the 534938032Speter remote identity can be queried. 535038032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 535138032Speter Some mailers, including procmail, require that the real 535238032Speter uid is left unchanged by sendmail. Problem noted by Per 535338032Speter Hedeland of Ericsson. 535438032Speter No longer is the src/obj*/Makefile selected from a large list -- it 535538032Speter is now generated using the information in BuildTools/OS/ -- 535638032Speter some of the details are determined dynamically via 535738032Speter BuildTools/bin/configure.sh. 535838032Speter The other programs in the sendmail distribution -- mail.local, 535938032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 536038032Speter the new Build method which creates an operating system 536138032Speter specific Makefile using the information in BuildTools. 536238032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 536338032Speter a failure on one message won't affect future messages to the 536438032Speter same host). This is necessary if the remote host sends 536538032Speter a 451 error if the domain of the sender does not resolve 536638032Speter as is common in anti-spam configurations. Problem noted 536738032Speter by Mitchell Blank Jr of Exec-PC. 536838032Speter New "discard" mailer for check_* rulesets and header checking 536938032Speter rulesets. If one of the above rulesets resolves to the 537038032Speter $#discard mailer, the commands will be accepted but the 537138032Speter message will be completely discarded after it is accepting. 537238032Speter This means that even if only one of the recipients 537338032Speter resolves to the $#discard mailer, none of the recipients 537438032Speter will receive the mail. Suggested by Brian Kantor. 537538032Speter All but the last cloned envelope of a split envelope were queued 537638032Speter instead of being delivered. Problem noted by John Caruso 537738032Speter of CNET: The Computer Network. 537838032Speter Fix deadlock situation in persistent host status file locking. 537938032Speter Syslog an error if a user forward file could not be read due to 538038032Speter an error. Patch from John Beck of Sun Microsystems. 538138032Speter Use the first name returned on machine lookups when canonifying a 538238032Speter hostname via NetInfo. Patch from Timm Wetzel of GWDG. 538338032Speter Clear the $&{client_addr}, $&{client_name}, and $&{client_port} 538438032Speter macros when delivering a bounce message to prevent 538538032Speter rejection by a check_compat ruleset which uses these macros. 538638032Speter Problem noted by Jens Hamisch of AgiX Internetservices GmbH. 538738032Speter If the check_relay ruleset resolves to the the error mailer, the 538838032Speter error in the $: portion of the resolved triplet is used 538938032Speter in the rejection message given to the remote machine. 539038032Speter Suggested by Scott Gifford of The Internet Ramp. 539138032Speter Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros 539238032Speter before calling the check_relay ruleset. Suggested by Scott 539338032Speter Gifford of The Internet Ramp. 539438032Speter Sendmail would get a segmentation fault if a mailer exited with an 539538032Speter exit code of 79. Problem noted by Aaron Schrab of ExecPC 539638032Speter Internet. Fix from Christophe Wolfhugel of the Pasteur 539738032Speter Institute. 539838032Speter Separate snprintf/vsnprintf routines into separate file for use by 539938032Speter mail.local. 540038032Speter Allow multiple map lookups on right hand side, e.g., 540138032Speter R$* $( host $1 $) $| $( passwd $1 $). Patch from 540238032Speter Christophe Wolfhugel of the Pasteur Institute. 540338032Speter Properly generate success DSN messages if requested for aliases 540438032Speter which have owner- aliases. Problem noted by Kari Hurtta 540538032Speter of the Finnish Meteorological Institute. 540638032Speter Properly display delayed-expansion macros ($&{macroname}) in 540738032Speter address test mode (-bt). Problem noted by Bryan Costales 540838032Speter of InfoBeat, Inc. 540938032Speter -qR could sometimes match names incorrectly.

Patch from Per Hedeland of 542138032Speter Ericsson. 542238032Speter Change persistent host status filename substitution so '/' is 542338032Speter replaced by ':' instead of '|' to avoid clashes. Also 542438032Speter avoid clashes with hostnames with leading dots. Fix from 542538032Speter Mitchell Blank Jr. of Exec-PC. 542638032Speter If the system lock table is full, only attempt to create a new 542738032Speter queue entry five times before giving up. Previously, it 542838032Speter was attempted indefinitely which could cause the partition 542938032Speter to run out of inodes. Problem noted by Suzie Weigand of 543038032Speter Stratus Computer, Inc. 543138032Speter In verbose mode, warn if the sendmail.cf version is less than the 543238032Speter currently supported version. 543338032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 543438032Speter from Randall S.

This database gives you the ability to allow 551038032Speter or refuse to accept mail from specified domains for 551138032Speter administrative reasons. By default, names that are listed 551238032Speter as "OK" in the access db are domain names, not host names. 551338032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 551438032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 551538032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 551638032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 551738032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 551838032Speter of FEATURE(access_db) and class 'R' to lookup individual 551938032Speter host names only. 552038032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 552138032Speter using % addressing is used, e.g. user%site@othersite, 552238032Speter and othersite is in class 'R', the check_rcpt ruleset 552338032Speter will strip @othersite and recheck user@site for relaying. 552438032Speter This feature changes that behavior. It should not be 552538032Speter needed for most installations. 552638032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 552738032Speter domain portion of the mail sender is a local host. This 552838032Speter should only be used if absolutely necessary as it opens 552938032Speter a window for spammers. Patch from Randall S.

Problem noted by Thomas J. 569338032Speter Arseneault of SRI International. 569438032Speter If an SMTP mailer used a non-standard port number for the outgoing 569538032Speter connection, it would be displayed incorrectly in verbose mode. 569638032Speter Problem noted by John Kennedy of Cal State University, Chico. 569738032Speter Log the ETRN parameter specified by the client before altering them 569838032Speter to internal form. Suggested by Bob Kupiec of GES-Verio. 569938032Speter EXPN and VRFY SMTP commands on malformed addresses were logging as 570038032Speter User unknown with bogus delay= values. Change them to log 570138032Speter the same as compliant addresses. Problem noted by Kari E. 570238032Speter Hurtta of the Finnish Meteorological Institute. 570338032Speter Ignore the debug resolver option unless using sendmail debug trace 570438032Speter option for resolver. Problem noted by Greg Nichols of Wind 570538032Speter River Systems. 570638032Speter If SingleThreadDelivery was enabled and the remote server returned a 570738032Speter protocol error on the DATA command, the connection would be 570838032Speter closed but the persistent host status file would not be 570938032Speter unlocked so other sendmail processes could not deliver to 571038032Speter that host. Problem noted by Peter Wemm of DIALix. 571138032Speter If queueing up a message due to an expensive mailer, don't increment 571238032Speter the number of delivery attempts or set the last delivery 571338032Speter attempt time so the message will be delivered on the next 571438032Speter queue run regardless of MinQueueAge. Problem noted by 571538032Speter Brian J. Coan of the Institute for Global Communications. 571638032Speter Authentication warnings of "Processed from queue _directory_" and 571738032Speter "Processed by _username_ with -C _filename_" would be logged 571838032Speter with the incorrect timestamp. Problem noted by Kari E. Hurtta 571938032Speter of the Finnish Meteorological Institute. 572038032Speter Use a better heuristic for detecting GDBM. 572138032Speter Log null connections on dropped connections. Problem noted by 572238032Speter Jon Lewis of Florida Digital Turnpike. 572338032Speter If class dbm maps are rebuilt, sendmail will now detect this and 572438032Speter reopen the map. Previously, they could give stale 572538032Speter results during a single message processing (but would 572638032Speter recover when the next message was received). Fix from 572738032Speter Joe Pruett of Q7 Enterprises. 572838032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 572938032Speter requests. Problem noted by Kari E. Hurtta of the 573038032Speter Finnish Meteorological Institute. 573138032Speter Do not send a bounce message back to the sender regarding bad 573238032Speter recipients if the SMTP connection is dropped before the 573338032Speter message is accepted. Problem noted by Kari E. Hurtta of the 573438032Speter Finnish Meteorological Institute. 573538032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 573638032Speter sendmail via a UNIX pipe. This will allow rulesets using 573738032Speter $&{client_name} to process without sending the string through 573838032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 573938032Speter A combination of deferred delivery mode, a double bounce situation, 574038032Speter and the inability to save a bounce message to 574138032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 574238032Speter to postmaster but not remove the offending envelope from the 574338032Speter queue causing it to create a new bounce message each time the 574438032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 574538032Speter Associates. 574638032Speter Remove newlines from hostname information returned via DNS. There are 574738032Speter no known security implications of newlines in hostnames as 574838032Speter sendmail filters newlines in all vital areas; however, this 574938032Speter could cause confusing error messages. 575038032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 575138032Speter rejected if any of the specified addresses were bad. This 575238032Speter behavior was modified to only reject the bad addresses and not 575338032Speter the entire message. Problem noted by Jozsef Hollosi of 575438032Speter SuperNet, Inc. 575538032Speter Use Timeout.fileopen when delivering mail to a file. Suggested by 575638032Speter Bryan Costales of InfoBeat, Inc. 575738032Speter Display the proper Final-Recipient on DSN messages for non-SMTP 575838032Speter mailers. Problem noted by Kari E. Hurtta of the 575938032Speter Finnish Meteorological Institute. 576038032Speter An error in calculating the available space in the list of addresses 576138032Speter for logging deliveries could cause an address to be silently 576238032Speter dropped. 576338032Speter Include the initial user environment if sendmail is restarted via 576438032Speter a HUP signal. This will give room for the process title. 576538032Speter Problem noted by Jon Lewis of Florida Digital Turnpike. 576638032Speter Mail could be delivered without a body if the machine does not 576738032Speter support flock locking and runs out of processes during 576838032Speter delivery. Fix from Chuck Lever of the University of Michigan. 576938032Speter Drop recipient address from 251 and 551 SMTP responses per RFC 821. 577038032Speter Problem noted by Kari E. Hurtta of the Finnish Meteorological 577138032Speter Institute. 577238032Speter Make sure non-rebuildable database maps are opened before the 577364562Sgshapiro rebuildable maps (i.e., alias files) in case the database maps 577438032Speter are needed for verifying the left hand side of the aliases. 577538032Speter Problem noted by Lloyd Parkes of Victoria University. 577638032Speter Make sure sender RFC822 source route addresses are alias expanded for 577738032Speter bounce messages. Problem noted by Juergen Georgi of 577838032Speter RUS University of Stuttgart. 577938032Speter Minor lint fixes. 578038032Speter Return a temporary error instead of a permanent error if an LDAP map 578138032Speter search returns an error. This will allow sequenced maps which 578238032Speter use other LDAP servers to be checked. Fix from Booker Bense 578338032Speter of Stanford University. 578438032Speter When automatically converting from quoted printable to 8bit text do 578538032Speter not pad bare linefeeds with a space. Problem noted by Theo 578638032Speter Nolte of the University of Technology Aachen, Germany. 578738032Speter Portability: 578838032Speter Non-standard C compilers may have had a problem compiling 578938032Speter conf.c due to a standard C external declaration of 579038032Speter setproctitle(). Problem noted by Ted Roberts of 579138032Speter Electronic Data Systems. 579238032Speter AUX: has a broken O_EXCL implementation. Reported by Jim 579338032Speter Jagielski of jaguNET Access Services. 579438032Speter BSD/OS: didn't compile if HASSETUSERCONTEXT was defined. 579538032Speter Digital UNIX: Digital UNIX (and possibly others) moves 579638032Speter loader environment variables into the loader memory 579738032Speter area. If one of these environment variables (such as 579838032Speter LD_LIBRARY_PATH) was the last environment variable, 579938032Speter an invalid memory address would be used by the process 580038032Speter title routine causing memory corruption. Problem 580138032Speter noted by Sam Hartman of Mesa Internet Systems. 580238032Speter GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused 580338032Speter chownsafe() to always return 0 even if the OS does 580438032Speter not permit file giveaways. Problem noted by 580538032Speter Yasutaka Sumi of The University of Tokyo. 580664562Sgshapiro IRIX6: Syslog buffer size set to 512 bytes. Reported by 580738032Speter Gerald Rinske of Siemens Business Services VAS. 580838032Speter Linux: Pad process title with NULLs.

Problem noted by 581838032Speter Stephen Ma of Jtec Pty Limited. 581938032Speter CONFIG: SINIX: Update from Gerald Rinske of Siemens Business 582038032Speter Services VAS. 582138032Speter MAKEMAP: Use a better heuristic for detecting GDBM. 582238032Speter CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff. 582338032Speter OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of 582438032Speter Ericsson. 582538032Speter 582664562Sgshapiro8.8.7/8.8.7 1997/08/03 582738032Speter If using Berkeley DB on systems without O_EXLOCK (open a file with 582838032Speter an exclusive lock already set -- i.e., almost all systems 582938032Speter except 4.4-BSD derived systems), the initial attempt at 583038032Speter rebuilding aliases file if the database didn't already 583138032Speter exist would fail. Patch from Raymund Will of LST Software 583238032Speter GmbH. 583338032Speter Bogus incoming SMTP commands would reset the SMTP conversation. 583438032Speter Problem noted by Fredrik J�nsson of the Royal Institute 583538032Speter of Technology, Stockholm. 583638032Speter Since TCP Wrappers includes setenv(), unsetenv(), and putenv(), 583738032Speter some environments could give "multiple definitions" for these 583838032Speter routines during compilation. If using TCP Wrappers, assume 583938032Speter that these routines are included as though they were in the 584038032Speter C library. Patch from Robert La Ferla. 584138032Speter When a NEWDB database map was rebuilt at the same time it was being 584238032Speter used by a queue run, the maps could be left locked for the 584338032Speter duration of the queue run, causing other processes to hang. 584438032Speter Problem noted by Kendall Libby of Shore.NET. 584538032Speter In some cases, NoRecipientAction=add-bcc was being ignored, so the 584638032Speter mail was passed on without any recipient header. This could 584738032Speter cause problems downstream. Problem noted by Xander Jansen 584838032Speter of SURFnet ExpertiseCentrum. 584938032Speter Give error when GDBM is used with sendmail. GDBM's locking and 585038032Speter linking of the .dir and .pag files interferes with sendmail's 585138032Speter locking and security checks. Problems noted by Fyodor 585238032Speter Yarochkin of the Kyrgyz Republic FreeNet. 585338032Speter Don't fsync qf files if SuperSafe option is not set. 585438032Speter Avoid extra calls to gethostbyname for addresses for which a 585538032Speter gethostbyaddr found no value. Also, ignore any returns 585638032Speter from gethostbyaddr that look like a dotted quad. 585738032Speter If PTR lookup fails when looking up an SMTP peer, don't tag it as 585838032Speter "may be forged", since at the network level we pretty much 585938032Speter have to assume that the information is good. 586038032Speter In some cases, errors during an SMTP session could leave files 586138032Speter open or locked. 586238032Speter Better handling of missing file descriptors (0, 1, 2) on startup. 586390792Sgshapiro Better handling of non-set-user-ID binaries -- avoids certain obnoxious 586438032Speter errors during testing. 586538032Speter Errors in file locking of NEWDB maps had the incorrect file name 586638032Speter printed in the error message. 586738032Speter If the AllowBogusHELO option were set and an EHLO with a bad or 586838032Speter missing parameter were issued, the EHLO behaved like a HELO. 586938032Speter Load limiting never kicked in for incoming SMTP transactions if the 587043730Speter DeliveryMode=background and any recipient was an alias or 587138032Speter had a .forward file. From Nik Conwell of Boston University. 587238032Speter On some non-Posix systems, the decision of whether chown(2) permits 587338032Speter file giveaway was undefined. From Tetsu Ushijima of the 587438032Speter Tokyo Institute of Technology. 587538032Speter Fix race condition that could cause the body of a message to be 587638032Speter lost (so only the header was delivered). This only occurs 587738032Speter on systems that do not use flock(2), and only when a queue 587838032Speter runner runs during a critical section in another message 587938032Speter delivery. Based on a patch from Steve Schweinhart of 588038032Speter Results Computing. 588138032Speter If a qf file was found in a mail queue directory that had a problem 588238032Speter (wrong ownership, bad format, etc.) and the file name was 588338032Speter exactly MAXQFNAME bytes long, then instead of being tried 588438032Speter once, it would be tried on every queue run. Problem noted 588538032Speter by Bryan Costales of Mercury Mail. 588638032Speter If the system supports an st_gen field in the status structure, 588738032Speter include it when reporting that a file has changed after open. 588838032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 588938032Speter This out to be checked as well as reported, since it is 589038032Speter theoretically possible for an attacker to remove a file after 589138032Speter it is opened and replace it with another file that has the 589238032Speter same i-number, but some filesystems (notably AFS) return 589338032Speter garbage in this field, and hence always look like the file 589438032Speter has changed. As a practical matter this is not a security 589538032Speter problem, since the files can be neither hard nor soft links, 589638032Speter and on no filesystem (that I am aware of) is it possible to 589738032Speter have two files on the same filesystem with the same i-number 589838032Speter simultaneously. 589938032Speter Delete the root Makefile from the distribution -- it is only for 590038032Speter use internally, and does not work at customer sites. 590138032Speter Fix botch that caused the second MAIL FROM: command in a single 590238032Speter transaction to clear the entire transaction. Problem 590338032Speter noted by John Kennedy of Cal State University, Chico. 590438032Speter Work properly on machines that have _PATH_VARTMP defined without 590538032Speter a trailing slash.

This makes it possible to create a root 598838032Speter owned file in an arbitrary directory by inserting the symlink 598938032Speter into a writable directory after the initial lstat(2) check 599038032Speter determined that the file did not exist. The only verified 599138032Speter example of a system having these odd semantics for O_EXCL 599238032Speter and symbolic links was HP-UX prior to version 9.07. Most 599338032Speter systems do not have the problem, since a exclusive create 599438032Speter of a file disallows symbolic links. Systems that have been 599538032Speter verified to NOT have the problem include AIX 3.x, *BSD, 599638032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 599738032Speter and Ultrix. This is a potential exposure on systems that 599838032Speter have this bug and which do not have a MAILER-DAEMON alias 599938032Speter pointing at a legitimate account, since this will cause old 600038032Speter mail to be dropped in /var/tmp/dead.letter. 600138032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 600238032Speter if maps or alias files are in world writable directories. 600338032Speter If your system has alias maps in writable directories, it 600438032Speter is potentially possible for an attacker to replace the .db 600538032Speter (or .dir and .pag) files by symbolic links pointing at 600638032Speter another database; this can be used either to expose 600738032Speter information (e.g., by pointing an alias file at /etc/spwd.db 600838032Speter and probing for accounts), or as a denial-of-service attack 600938032Speter (by trashing the password database). The fix disallows 601038032Speter symbolic links entirely when rebuilding alias files or on 601138032Speter maps that are in writable directories, and always warns on 601238032Speter writable directories; 8.9 will probably consider writable 601338032Speter directories to be fatal errors. This does not represent an 601438032Speter exposure on systems that have alias files in unwritable 601538032Speter system directories. 601638032Speter SECURITY: disallow .forward or :include: files that are links (hard 601738032Speter or soft) if the parent directory (or any directory in the 601838032Speter path) is writable by anyone other than the owner. This is 601938032Speter similar to the previous case for user files. This change 602038032Speter should not affect most systems, but is necessary to prevent 602138032Speter an attacker who can write the directory from pointing such 602238032Speter files at other files that are readable only by the owner. 602338032Speter SECURITY: Tighten safechown rules: many systems will say that they 602438032Speter have a safe (restricted to root) chown even on files that 602538032Speter are mounted from another system that allows owners to give 602638032Speter away files. The new rules are very strict, trusting file 602738032Speter ownership only in those few cases where the system has 602838032Speter been verified to be at least as paranoid as necessary. 602938032Speter However, it is possible to relax the rules to partially 603038032Speter trust the ownership if the directory path is not world or 603138032Speter group writable. This might allow someone who has a legitimate 603238032Speter :include: file (referenced directly from /etc/aliases) to 603338032Speter become another non-root user if the :include: file is in a 603438032Speter non-writable directory on an NFS-mounted filesystem where 603538032Speter the local system says that giveaway is denied but it is 603638032Speter actually permitted. I believe this to be a very small set 603738032Speter of cases. If in doubt, do not point :include: aliases at 603838032Speter NFS-mounted filesystems. 603938032Speter SECURITY: When setting a numeric group id using the RunAsUser option 604038032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 604138032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 604238032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 604338032Speter The user id was still set properly. Problem noted by Uli 604438032Speter Pralle of the Technical University of Berlin. 604538032Speter Save the initial gid set for use when checking for if the 604638032Speter PrivacyOptions=restrictmailq option is set. Problem reported 604738032Speter by Wolfgang Ley of DFN-CERT. 604838032Speter Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a 604938032Speter failure on one message won't affect future messages to the 605038032Speter same host). 605138032Speter IP source route printing had an "off by one" error that would 605238032Speter affect any options that came after the route option. Patch 605338032Speter from Theo de Raadt. 605438032Speter The "Message is too large" error didn't successfully bounce the error 605538032Speter back to the sender. Problem reported by Stephen More of 605638032Speter PSI; patch from Gregory Neil Shapiro of WPI. 605738032Speter Change SMTP status code 553 to map into Extended code 5.1.0 (instead 605838032Speter of 5.1.3); it apparently gets used in multiple ways. 605938032Speter Suggested by John Myers of Portola Communications. 606038032Speter Fix possible extra null byte generated during collection if errors 606138032Speter occur at the beginning of the stream. Patch contributed by 606238032Speter Andrey A. Chernov and Gregory Neil Shapiro. 606338032Speter Code changes to avoid possible reentrant call of malloc/free within 606438032Speter a signal handler. Problem noted by John Beck of Sun 606538032Speter Microsystems. 606638032Speter Move map initialization to be earlier so that check_relay ruleset 606738032Speter will have the latest version of the map data. Problem noted 606838032Speter by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro. 606938032Speter If there are fatal errors during the collection phase (e.g., message 607038032Speter too large) don't send the bogus message. 607138032Speter Avoid "cannot open xfAAA00000" messages when sending to aliases that 607238032Speter have errors and have owner- aliases. Problem noted by Michael 607338032Speter Barber of MTU; fix from Gregory Neil Shapiro of WPI. 607438032Speter Avoid null pointer dereference on illegal Boundary= parameters in 607538032Speter multipart/mixed Content-Type: header. Problem noted by 607638032Speter Richard Muirden of RMIT University. 607738032Speter Always print error messages during newaliases (-bi) even if the 607838032Speter ErrorMode is not set to "print". Fix from Gregory Neil 607938032Speter Shapiro. 608038032Speter Test mode could core dump if you did a /map lookup in an optional map 608138032Speter that could not be opened. Based on a fix from John Beck of 608238032Speter Sun Microsystems. 608338032Speter If DNS is misconfigured so that the last MX record tried points to 608438032Speter a host that does not have an A record, but other MX records 608538032Speter pointed to something reasonable, don't bounce the message 608638032Speter with a "host unknown" error. Note that this should really 608738032Speter be fixed in the zone file for the domain. Problem noted by 608838032Speter Joe Rhett of Navigist, Inc. 608938032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 609038032Speter the message as having been tried; otherwise the next queue 609138032Speter run will not realize that this is a second attempt and will 609238032Speter retry immediately. Problem noted by Bryan Costales of 609338032Speter Mercury Mail. 609438032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 609538032Speter will be run until the later setting of the clock is reached. 609638032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 609738032Speter Morgan Stanley. 609838032Speter If the load average rises above the cutoff threshold (above which 609938032Speter sendmail will not process the queue at all) during a queue 610038032Speter run, abort the queue run immediately. Problem noted by 610138032Speter Bryan Costales of Mercury Mail. 610238032Speter The variable queue processing algorithm (based on the message size, 610338032Speter number of recipients, message precedence, and job age) was 610438032Speter non-functional -- either the entire queue was processed or 610538032Speter none of the queue was processed. The updated algorithm 610638032Speter does no queue run if a single recipient zero size job will 610738032Speter not be run. 610838032Speter If there is a fatal ("panic") message that will cause sendmail to 610938032Speter die immediately, never hold the error message for future 611038032Speter printing. 611138032Speter Force ErrorMode=print in -bt mode so that all errors are printed 611238032Speter regardless of the setting of the ErrorMode option in the 611338032Speter configuration file. Patch from Gregory Neil Shapiro. 611438032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 611538032Speter routine available in one of the libraries. Use it in conf.h. 611638032Speter The -m (match only) flag now works on host class maps. 611738032Speter If class hash or btree maps are rebuilt, sendmail will now detect 611838032Speter this and reopen the map. Previously, they could give 611938032Speter erroneous results during a single message processing 612038032Speter (but would recover when the next message was received). 612138032Speter Don't delete zero length queue files when doing queue runs until the 612238032Speter files are at least ten minutes old. This avoids a potential 612338032Speter race condition: the creator creates the qf file, getting back 612438032Speter a file descriptor. The queue runner locks it and deletes it 612538032Speter because it is zero length. The creator then writes the 612638032Speter descriptor that is now for a disconnected file, and the 612738032Speter job goes away. Based on a suggestion by Bryan Costales. 612838032Speter When determining the "validated" host name ($_ macro), do a forward 612938032Speter (A) DNS lookup on the result of the PTR lookup and compare 613038032Speter results. If they differ or if the PTR lookup fails, tag the 613138032Speter address as "may be forged". 613238032Speter Log null connections (i.e., hosts that connect but do not do any 613338032Speter substantive activity on the connection before disconnecting; 613438032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 613538032Speter Always permit "writes" to /dev/null regardless of the link count. 613638032Speter This is safe because /dev/null is special cased, and no open 613738032Speter or write is ever actually attempted. Patch from Villy Kruse 613838032Speter of TwinCom. 613938032Speter If a message cannot be sent because of a 552 (exceeded storage 614038032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 614138032Speter was given, don't return the body in the bounce, since there 614238032Speter is a very good chance that the message will double-bounce. 614338032Speter Fix possible line truncation if a quoted-printable had an =00 escape 614438032Speter in the body. Problem noted by Charles Karney of the Princeton 614538032Speter Plasma Physics Laboratory. 614638032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 614738032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 614838032Speter Institute. 614938032Speter The MaxDaemonChildren option wasn't applying to queue runs as 615038032Speter documented. Note that this increases the potential denial 615138032Speter of service problems with this option: an attacker can 615238032Speter connect many times, and thereby lock out queue runs as well 615338032Speter as incoming connections. If you use this option, you should 615438032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 615538032Speter to avoid this attack. Failure to limit noted by Matthew 615638032Speter Dillon of BEST Internet Communications. 615738032Speter Always give a message in newaliases if alias files cannot be 615838032Speter opened instead of failing silently. Suggested by Gregory 615938032Speter Neil Shapiro. This change makes the code match the O'Reilly 616038032Speter book (2nd edition). 616138032Speter Some older versions of the resolver could return with h_errno == -1 616238032Speter if no name server could be reached, causing mail to bounce 616338032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 616438032Speter John Beck of SunSoft. 616538032Speter If a :include: file is owned by a user that does not have an entry 616638032Speter in the passwd file, sendmail could dereference a null pointer. 616738032Speter Problem noted by Satish Mynam of Sun Microsystems. 616838032Speter Take precautions to make sure that the SMTP protocol cannot get out 616938032Speter of sync if (for example) an alias file cannot be opened. 617038032Speter Fix a possible race condition that can cause a SIGALRM to come in 617138032Speter immediately after a SIGHUP, causing the new sendmail to die. 617238032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 617338032Speter from Villy Kruse of TwinCom. 617438032Speter Ignore improperly formatted SMTP reply codes. Previously these were 617538032Speter partially processed, which could cause confusing error 617638032Speter returns. 617738032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 617838032Speter on some architectures. 617938032Speter Portability: 618038032Speter A/UX: from Jim Jagielski of NASA/GSFC. 618138032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 618238032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 618338032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 618438032Speter defined. Problem reported by A Sun of the University 618538032Speter of Washington. 618638032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 618738032Speter the system rather than guessing at compile time. 618838032Speter Patch contributed by John Beck of Sun Microsystems. 618938032Speter Intel Paragon: from Wendy Lin of Purdue University. 619038032Speter GNU Hurd: from Miles Bader of the GNU project. 619138032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 619238032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 619338032Speter Unfortunately releasing them opens a race condition, 619438032Speter but there appears to be no fix for this. Patch from 619538032Speter Gregory Neil Shapiro. 619638032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 619738032Speter Solaris: a bug in strcasecmp caused characters with the 619838032Speter high order bit set to apparently randomly match 619938032Speter letters -- for example, $| (0233) matches "i" and "I". 620038032Speter Problem noted by John Gregson of the University of 620138032Speter Cambridge. 620238032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x.

Problem noted by Gregory Neil Shapiro. 621838032Speter CONFIG: Retain "+detail" information when forwarding mail to a 621938032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 622038032Speter Guenther of Gustavus Adolphus College. 622138032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 622238032Speter rules are the same as for aliasing. Based on a patch from 622338032Speter Gregory Neil Shapiro. 622438032Speter CONFIG: Break up parsing rules into several pieces; this should 622538032Speter have no functional change in this release, but makes it 622638032Speter possible to have better anti-spam rulesets in the future. 622738032Speter CONFIG: Disallow double dots in host names to avoid having the 622838032Speter HostStatusDirectory store status under the wrong name. 622938032Speter In some cases this can be used as a denial-of-service attack. 623038032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 623138032Speter Gregory Neil Shapiro. 623238032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 623338032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 623438032Speter don't include From_, and convert to 8-bit). Suggestions 623538032Speter from Kimmo Suominen and Roderick Schertler. 623664562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 623738032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 623838032Speter was specified, even when it wasn't. 623938032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 624038032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 624138032Speter "slip in" a symbolic link between the lstat(2) call and the 624238032Speter exclusive open. This is only a problem on System V derived 624338032Speter systems that allow an exclusive create on files that are 624438032Speter symbolic links pointing nowhere. 624538032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 624638032Speter not reset back to root, which on some systems would cause 624738032Speter later mailboxes to fail. Also, any partial message would 624838032Speter not be truncated, which could result in repeated deliveries. 624938032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 625038032Speter developers). 625138032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 625238032Speter change to the sendmail map code was made in 8.8.3. Problem 625338032Speter noted by Gregory Neil Shapiro. 625438032Speter MAKEMAP: Give warnings on file problems such as map files that are 625590792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 625638032Speter often run as root and hence has the potential for the same 625738032Speter sorts of problems as alias rebuilds. 625838032Speter MAKEMAP: Change compilation so that it will link properly on 625938032Speter NEXTSTEP. 626038032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 626138032Speter Accept an optional list of arguments following the server 626238032Speter name for the ETRN arguments to use (instead of $=w). Other 626338032Speter miscellaneous bug fixes. From Christian von Roques via 626438032Speter John Beck of Sun Microsystems. 626538032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 626638032Speter Perl script converts GECOS information in the /etc/passwd 626738032Speter file into aliases, allowing for faster access to full name 626838032Speter lookups; it is also clever about adding aliases (to root) 626938032Speter for system accounts. 627038032Speter NEW FILES: 627138032Speter src/safefile.c 627238032Speter cf/ostype/gnuhurd.m4 627338032Speter cf/ostype/irix6.m4 627438032Speter contrib/passwd-to-alias.pl 627538032Speter src/Makefiles/Makefile.IRIX64.6.1 627638032Speter src/Makefiles/Makefile.IRIX64.6.x 627738032Speter RENAMED FILES: 627838032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 627938032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 628038032Speter 628164562Sgshapiro8.8.5/8.8.5 1997/01/21 628238032Speter SECURITY: Clear out group list during startup. Without this, sendmail 628338032Speter will continue to run with the group permissions of the caller, 628438032Speter even if RunAsUser is specified. 628538032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 628638032Speter to any known attack, but it's best to be conservative. 628738032Speter Suggested by Peter Wemm of DIALix. 628838032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 628938032Speter security implications. Patch from Alex Garthwaite of the 629038032Speter University of Pennsylvania. 629138032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 629238032Speter would truncate the address after "Full". Although the -f 629338032Speter syntax is incorrect (since it is in the envelope, it 629438032Speter shouldn't have comments and full names), the failure mode 629538032Speter was unnecessarily awful. 629638032Speter Fix a possible null pointer dereference when converting 8-bit data 629738032Speter to a 7-bit format. Problem noted by Jim Hutchins of 629838032Speter Sandia National Labs and David James of British Telecom. 629938032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 630038032Speter runs. Although this really shouldn't be used (F=9 is for 630138032Speter final delivery only, and using it on an SMTP mailer makes 630238032Speter it possible for a message to be converted from 8->7->8->7 630338032Speter bits several times), it shouldn't have failed with a syserr. 630438032Speter Problem noted by Eric Hagberg of Morgan Stanley. 630538032Speter _Really_ fix the multiple :maildrop code in the user database 630638032Speter module. Patch from Roy Mongiovi of Georgia Tech. 630738032Speter Let F lines in the configuration file actually read root-only 630838032Speter files if the configuration file is safe. Based on a 630938032Speter patch from Keith Reynolds of SCO. 631038032Speter ETRN followed by QUIT would hold the connection open until the queue 631138032Speter run completed. Problem noted by Truck Lewis of TDK 631238032Speter Semiconductor Corp. 631338032Speter It turns out that despite the documentation, the TCP wrappers library 631438032Speter does _not_ log rejected connections. Do the logging ourselves. 631538032Speter Problem noted by Fletcher Mattox of the University of Texas 631638032Speter at Austin. 631738032Speter If sendmail finds a qf file in its queue directory that is an unknown 631838032Speter version (e.g., when backing out to an old version), the 631938032Speter error is reported on every queue run. Change it to only 632038032Speter give the error once (and rename the qf => Qf). Patch from 632138032Speter William A. Gianopoulos of Raytheon Company. 632238032Speter Start a new session when doing background delivery; currently it 632338032Speter ignored signals but didn't start a new signal, that caused 632438032Speter some problems if a background process tried to send mail 632538032Speter under certain circumstances. Problem noted by Eric Hagberg 632638032Speter of Morgan Stanley; fix from Kari Hurtta. 632738032Speter Simplify test for skipping a queue run to just check if the current 632838032Speter load average is >= the queueing load average. Previously 632938032Speter the check factored in some other parameters that caused it 633038032Speter to essentially never skip the queue run. Patch from Bryan 633138032Speter Costales. 633238032Speter If the SMTP server is running in "nullserver" mode (that is, it is 633338032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 633438032Speter (25) commands; this helps prevent a bad guy from putting 633538032Speter you into a tight loop as a denial-of-service attack. Based 633638032Speter on an e-mail conversation with Brad Knowles of AOL. 633738032Speter Slow down when too many "light weight" commands have been issued; 633838032Speter this helps prevent a class of denial-of-service attacks. 633938032Speter The current values and defaults are: 634038032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 634138032Speter MAXHELOCOMMANDS 3 HELO, EHLO 634238032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 634338032Speter MAXETRNCOMMANDS 8 ETRN 634438032Speter These will probably be configurable in a future release. 634538032Speter On systems that have uid_t typedefed to be an unsigned short, programs 634638032Speter that had the F=S flag and no U= equate would be invoked with 634738032Speter the real uid set to 65535 rather than being left unchanged. 634838032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 634938032Speter by Steve Hubert of the University of Washington, Seattle. 635038032Speter Mail that was Quoted-Printable encoded and had a soft line break on 635138032Speter the last line (i.e., an incomplete continuation) had the last 635238032Speter line dropped. Since this appears to be illegal it isn't 635338032Speter clear what to do with it, but flushing the last line seems 635438032Speter to be a better "fail soft" approach. Based on a patch from 635538032Speter Eric Hagberg. 635638032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 635738032Speter bogus HELO command still causes the "Polite people say HELO 635838032Speter first" error message. Problem pointed out by Chris Thomas 635938032Speter of UCLA; patch from John Beck of SunSoft. 636038032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 636171345Sgshapiro in PrivacyOptions. The -q shouldn't turn this command off. 636271345Sgshapiro Problem noted by Murray Kucherawy of Pacific Bell Internet; 636371345Sgshapiro based on a patch from Gregory Neil Shapiro of WPI. 636438032Speter Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation) 636538032Speter in a DATA transaction to be sticky; these can occur because 636638032Speter a message is too large, and smaller messages should still go 636738032Speter through. Problem noted by Matt Dillon of Best Internet 636838032Speter Communications. 636938032Speter In some cases bounces were saved in /var/tmp/dead.letter even if they 637038032Speter had been successfully delivered to the envelope sender. 637138032Speter Problem noted Eric Hagberg of Morgan Stanley; solution from 637238032Speter Gregory Neil Shapiro of WPI. 637338032Speter Give better diagnostics on long alias lines. Based on code contributed 637438032Speter by Patrick Gosling of the University of Cambridge. 637538032Speter Increase the number of virtual interfaces that will be probed for 637638032Speter alternate names.

Problem noted by Ronan KERYELL 640138032Speter of Centre de Recherche en Informatique de l'�cole Nationale 640238032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 640338032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 640438032Speter such as LUSER_RELAY. This change permits the following 640538032Speter syntaxes: ``local:'' will send to the same user on the 640638032Speter local machine (e.g., in a mailertable entry for "host", 640738032Speter ``local:'' will cause an address addressed to user@host to 640838032Speter go to user on the local machone). ``local:user'' will send 640938032Speter to the named user on the local machine. ``local:user@host'' 641038032Speter is equivalent to ``local:user'' (the host is ignored). In 641138032Speter all cases, the original user@host is passed in $@ (i.e., the 641238032Speter detail information). Inspired by a report from Michael Fuhr. 641338032Speter CONFIG: Strip quotes from the first word of an "error:" host 641438032Speter indication. This lets you set (for example) the LUSER_RELAY 641538032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 641638032Speter of the \" so that the resulting string is properly quoted. 641738032Speter Problem noted by Gregory Neil Shapiro of WPI. 641838032Speter OP.ME: documentation was inconsistent about whether sendmail did a 641938032Speter NOOP or a RSET to probe the connection (it does a RSET). 642038032Speter Inconsistency noted by Deeran Peethamparam. 642138032Speter OP.ME: insert additional blank pages so it will print properly on 642238032Speter a duplex printer. From Matthew Black of Cal State University, 642338032Speter Long Beach. 642438032Speter 642564562Sgshapiro8.8.4/8.8.4 1996/12/02 642638032Speter SECURITY: under some circumstances, an attacker could get additional 642738032Speter permissions by hard linking to files that were group 642838032Speter writable by the attacker. The solution is to disallow any 642938032Speter files that have hard links -- this will affect .forward, 643038032Speter :include:, and output files. Problem noted by Terry 643138032Speter Kyriacopoulos of Interlog Internet Services. As a 643238032Speter workaround, set UnsafeGroupWrites -- always a good idea. 643338032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 643438032Speter is, it is possible to do a denial-of-service attack on 643538032Speter MX hosts that rely on the use of the null MX list. There 643638032Speter is no danger if you have this option turned off (the default). 643738032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 643838032Speter unsafe. I know of no specific attack against this, although 643938032Speter a denial-of-service attack is probably possible, but in theory 644038032Speter you should not be able to safely tweak anything that affects 644138032Speter the permissions that are used when mail is delivered. 644238032Speter Purgestat could go into an infinite loop if one of the host status 644338032Speter directories somehow became empty. Problem noted by Roy 644438032Speter Mongiovi of Georgia Tech. 644538032Speter Processes got "lost" when counting children due to a race condition. 644638032Speter This caused "proc_list_probe: lost pid" messages to be logged. 644738032Speter Problem noted by several people. 644838032Speter On systems with System V SIGCLD child signal semantics (notably AIX 644938032Speter and HP-UX), mail transactions would print the message "451 645038032Speter SMTP-MAIL: lost child: No child processes". Problem noted 645138032Speter by several people. 645238032Speter Miscellaneous compiler warnings on picky compilers (or when setting 645338032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 645438032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 645538032Speter not be persistent between runs, since they are based on the 645638032Speter message rather than the host. Problem noted by Matt Dillon 645738032Speter of Best Internet Communications. 645838032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 645938032Speter of NCR (a.k.a., AT&T Global Information Solutions). 646038032Speter Avoid the possibility of having a child daemon run to completion 646138032Speter (including closing the SMTP socket) before the parent has 646238032Speter had a chance to close the socket; this can cause the parent 646338032Speter to hang for a long time waiting for the socket to drain. 646438032Speter Patch from Don Lewis of TDK Semiconductor. 646538032Speter If the fork() failed in a queue run, the queue runners would not be 646638032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 646738032Speter Some error conditions in ETRN could cause output without an SMTP 646838032Speter status code. Problem noted by Don Lewis. 646938032Speter Multiple :maildrop addresses in the user database didn't work properly. 647038032Speter Patch from Roy Mongiovi of Georgia Tech. 647138032Speter Add ".db" automatically onto any user database spec that does not 647238032Speter already have it; this is for consistency with makemap, the 647338032Speter K line, and the documentation. Inconsistency pointed out 647438032Speter by Roy Mongiovi. 647538032Speter Allow sendmail to be properly called in nohup mode. Patch from 647638032Speter Kyle Jones of UUNET. 647738032Speter Change ETRN to ignore but still update host status files; previously 647838032Speter it would ignore them and not save the updated status, which 647938032Speter caused stale information to be maintained. Based on a patch 648038032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 648138032Speter ETRN ignore the MinQueueAge option. 648238032Speter Patch long term host status to recover more gracefully from an empty 648338032Speter host status file condition. Patch from NAKAMURA Motonori 648438032Speter of Kyoto University. 648538032Speter Several patches to signal handling code to fix potential race 648638032Speter conditions from Don Lewis. 648738032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 648838032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 648938032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 649038032Speter compile flag; use NETINET instead. Solution based on a 649138032Speter patch from Bryan Costales. 649238032Speter PORTABILITY FIXES: 649338032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 649438032Speter /etc/security/passwd file when called as root.

Problem noted by Steve 654138032Speter Hubert of the University of Washington, Seattle. 654238032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 654338032Speter Problem reported by Tom Smith of Digital Equipment Corp. 654438032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 654538032Speter size PACKETSZ (512) is not sufficient for some nameserver 654638032Speter answers containing very many resource records. The resolver 654738032Speter may also switch to TCP and retry if it detects UDP packet 654838032Speter overflow. Also, allow for the fact that the resolver 654938032Speter routines res_query and res_search return the size of the 655038032Speter *un*truncated answer in case the supplied answer buffer it 655138032Speter not big enough to accommodate the entire answer. Patch from 655238032Speter Eric Wassenaar. 655338032Speter Improvements to MaxDaemonChildren code. If you think you have too 655438032Speter many children, probe the ones you have to verify that they 655538032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 655638032Speter Also, do this probe before growing the vector of children 655738032Speter pids; this previously caused the vector to grow indefinitely 655838032Speter due to a race condition. Problem reported by Kyle Jones of 655938032Speter UUNET. 656038032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 656138032Speter O_EXLOCK to zero; this fools the map compilation code into 656238032Speter thinking that it can avoid race conditions by locking on open. 656338032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 656438032Speter Leif Erlingsson of Data Lege. 656538032Speter Always call res_init() on startup (if compiled in, of course) to 656638032Speter allow the sendmail.cf file to tweak resolver flags; without 656738032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 656838032Speter Andrew Sun of Merrill Lynch. 656938032Speter Improvements to host status printing code. Suggested by Steve Hubert 657038032Speter of the University of Washington, Seattle. 657138032Speter Change MinQueueAge option processing to do the check for the job age 657238032Speter when reading the queue file, rather than at the end; this 657338032Speter avoids parsing the addresses, which can do DNS lookups. 657438032Speter Problem noted by John Beck of InReference, Inc. 657538032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 657638032Speter properly escaped. Problem noted by Peter Nilsson of the 657738032Speter University of Linkoping. 657838032Speter In some cases, sendmail would retain root permissions during queue 657938032Speter runs even if RunAsUser was set. Problem noted by Mark 658038032Speter Thomas of Mark G. Thomas Consulting. 658138032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 658238032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 658338032Speter the envelope, and the receiving SMTP server speaks DSN, then 658438032Speter the DSN would be both generated locally and propagated to the 658538032Speter other end. 658638032Speter The U= mailer field didn't correctly extract the group id if the 658738032Speter user id was numeric. Problem noted by Kenneth Herron of 658838032Speter MCI Telecommunications Communications. 658938032Speter If a message exceeded the fixed maximum size on input, the body of 659038032Speter the message was included in the bounce. Note that this did 659138032Speter not occur if it exceeded the maximum _output_ size. Problem 659238032Speter reported by Kyle Jones of UUNET. 659338032Speter PORTABILITY FIXES: 659438032Speter AIX4: 4.1 doesn't have a working setreuid(2); change the 659538032Speter AIX4 defines to use seteuid(2) instead, which 659638032Speter works on 4.1 as well as 4.2. Problem noted by 659738032Speter H�kan Lindholm of interAF, Sweden. 659838032Speter AIX4: use tzname[] vector to determine time zone name. 659938032Speter Patch from NAKAMURA Motonori of Kyoto University. 660038032Speter MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support. 660138032Speter Contributed by Paul DuBois <dubois@primate.wisc.edu>. 660238032Speter Solaris: kstat(3k) support for retrieving the load average. 660338032Speter This adds the LA_KSTAT definition for LA_TYPE. 660438032Speter The outline of the implementation was contributed 660538032Speter by Michael Tokarev of Telecom Service, JSC, Moscow. 660638032Speter HP-UX 10.0 gripes about the (perfectly legal!) forward 660738032Speter declaration of struct rusage at the top of conf.h; 660838032Speter change it to only be included if you are using gcc, 660938032Speter which is apparently the only compiler that requires 661038032Speter it in the first place. Problem noted by Jeff 661138032Speter Earickson of Colby College. 661238032Speter IRIX: don't default to using gcc. IRIX is a civilized 661338032Speter operating system that comes with a decent compiler 661438032Speter by default. Problem noted by Barry Bouwsma and 661538032Speter Kari Hurtta. 661638032Speter CONFIG: specify F=9 as default in FEATURE(local_procmail) for 661738032Speter consistency with other local mailers. Inconsistency 661838032Speter pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>. 661938032Speter CONFIG: if the "limited best mx" feature is used (to reduce DNS 662038032Speter overhead) as part of the bestmx_is_local feature, the 662138032Speter domain part was dropped from the name. Patch from Steve 662238032Speter Hubert of the University of Washington, Seattle. 662338032Speter CONFIG: catch addresses of the form "user@.dom.ain"; these could 662438032Speter end up being translated to the null host name, which would 662538032Speter return any entry in /etc/hosts that had a space at the end 662638032Speter of the line. Problem noted by Steve Hubert of the 662738032Speter University of Washington, Seattle. 662838032Speter CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer 662938032Speter Polytechnic Institute. 663038032Speter MAKEMAP: tweak hash and btree parameters for better performance. 663138032Speter Patch from Matt Dillon of Best Internet Communications. 663238032Speter NEW FILES: 663338032Speter src/Makefiles/Makefile.Linux.ppc 663438032Speter cf/ostype/aix4.m4 663538032Speter cf/ostype/mklinux.m4 663638032Speter 663764562Sgshapiro8.8.2/8.8.2 1996/10/18 663838032Speter SECURITY: fix a botch in the 7-bit MIME patch; the previous patch 663938032Speter changed the code but didn't fix the problem. 664038032Speter PORTABILITY FIXES: 664138032Speter Solaris: Don't use the system getusershell(3); it can 664238032Speter apparently corrupt the heap in some circumstances. 664338032Speter Problem found by Ken Pizzini of Spry, Inc. 664438032Speter OP.ME: document several mailer flags that were accidentally omitted 664538032Speter from this document. These flags were F=d, F=j, F=R, and F=9. 664638032Speter CONFIG: no changes. 664738032Speter 664864562Sgshapiro8.8.1/8.8.1 1996/10/17 664938032Speter SECURITY: unset all environment variables that the resolver will 665038032Speter examine during queue runs and daemon mode. Problem noted 665138032Speter by Dan Bernstein of the University of Illinois at Chicago. 665238032Speter SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain 665338032Speter message could overflow a buffer if it was converted back 665438032Speter to 8 bits. This caused core dumps and has the potential 665538032Speter for a remote attack. Problem first noted by Gregory Shapiro 665638032Speter of WPI. 665738032Speter Avoid duplicate deliveries of error messages on systems that don't 665838032Speter have flock(2) support. Patch from Motonori Nakamura of 665938032Speter Kyoto University. 666038032Speter Ignore null FallBackMX (V) options. If this option is null (as 666138032Speter opposed to undefined) it can cause "null signature" syserrs 666238032Speter on illegal host names. 666338032Speter If a Base64 encoded text/plain message has no trailing newline in 666438032Speter the encoded text, conversion back to 8 bits will drop the 666538032Speter final line. Problem noted by Pierre David. 666638032Speter If running with a RunAsUser, sendmail would give bogus "cannot 666738032Speter setuid" (or seteuid, or setreuid) messages on some systems. 666838032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 666938032Speter Always print error messages in -bv mode -- previously, -bv would 667038032Speter be absolutely silent on errors if the error mode was sent 667138032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 667238032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 667338032Speter term host status. This is necessary because it is common 667438032Speter to do this when you know a host has just come back up. 667538032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 667638032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 667738032Speter University of Leicester. 667838032Speter If a service (such as NIS) is specified as the last entry in the 667938032Speter service switch, but that service is not compiled in, sendmail 668038032Speter would return a temporary failure when an entry was not found 668138032Speter in the map. This caused the message to be queued instead of 668238032Speter bouncing immediately. Problem noted by Harry Edmon of the 668338032Speter University of Washington. 668438032Speter PORTABILITY FIXES: 668538032Speter Solaris 2.3 had compilation problems in conf.c. Several 668638032Speter people pointed this out. 668738032Speter NetBSD from Charles Hannum of MIT. 668838032Speter AIX4 improvements based on info from Steve Bauer of South 668938032Speter Dakota School of Mines & Technology. 669038032Speter CONFIG: ``error:code message'' syntax was broken in virtusertable. 669138032Speter Patch from Gil Kloepfer Jr. 669238032Speter CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set 669338032Speter using MASQUERADE_DOMAIN) were not masqueraded unless they 669438032Speter were also in $=w. Problem noted by Zoltan Basti of 669538032Speter Softec. 669638032Speter MAIL.LOCAL: patches to compile and link cleanly on AIX. Based 669738032Speter on a patch from Eric Hagberg of Morgan Stanley. 669838032Speter MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan 669938032Speter of Stanford via Robert La Ferla. 670038032Speter 670164562Sgshapiro8.8.0/8.8.0 1996/09/26 670238032Speter Under some circumstances, Bcc: headers would not be properly 670338032Speter deleted. Pointed out by Jonathan Kamens of OpenVision. 670438032Speter Log a warning if the sendmail daemon is invoked without a full 670538032Speter pathname, which prevents "kill -1" from working. I was 670638032Speter urged to put this in by Andrey A. Chernov of DEMOS (Russia). 670738032Speter Fix small buffer overflow. Since the data in this buffer was not 670838032Speter read externally, there was no security problem (and in fact 670938032Speter probably wouldn't really overflow on most compilers). Pointed 671038032Speter out by KIZU takashi of Osaka University. 671138032Speter Fix problem causing domain literals such as [1.2.3.4] to be ignored 671238032Speter if a FallbackMXHost was specified in the configuration file 671338032Speter -- all mail would be sent to the fallback even if the original 671438032Speter host was accessible. Pointed out by Munenari Hirayama of 671538032Speter NSC (Japan). 671638032Speter A message that didn't terminate with a newline would (sometimes) not 671738032Speter have the trailing "." added properly in the SMTP dialogue, 671838032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 671938032Speter The DaemonPortOptions suboption to bind to a particular address was 672038032Speter incorrect and nonfunctional due to a misunderstanding of the 672138032Speter semantics of binding on a passive socket. Patch from 672238032Speter NIIBE Yutaka of Mitsubishi Research Institute. 672338032Speter Increase the number of MX hosts for a single name to 100 to better 672438032Speter handle the truly huge service providers such as AOL, which 672538032Speter has 13 at the moment (and climbing). In order to avoid 672638032Speter trashing memory, the buffer for all names has only been 672738032Speter slightly increased in size, to 12.8K from 10.2K -- this means 672838032Speter that if a single name had 100 MX records, the average size 672938032Speter of those records could not exceed 128 bytes. Requested by 673038032Speter Brad Knowles of America On Line. 673138032Speter Restore use of IDENT returns where the OSTYPE field equals "OTHER". 673238032Speter Urged by Dan Bernstein of U.C. Berkeley. 673338032Speter Print q_statdate and q_specificity in address structure debugging 673438032Speter printout. 673538032Speter Expand MCI structure flag bits for debugging output. 673638032Speter Support IPv6-style domain literals, which can have colons between 673738032Speter square braces. 673838032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 673938032Speter this is an attempt to track down a bug that one person seems 674038032Speter to be having (it may be a Solaris bug!). 674138032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 674238032Speter this caused the NOTIFY info to sometimes be lost. Problem 674338032Speter pointed out by Claus Assmann of the 674438032Speter Christian-Albrechts-University of Kiel. 674538032Speter The statistics gathered in the sendmail.st file were too high; in 674638032Speter some cases failures (e.g., user unknown or temporary failure) 674738032Speter would count as a delivery as far as the statistics were 674838032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 674938032Speter Systems that don't have flock() would not send split envelopes in 675038032Speter the initial run. Problem pointed out by Leonard Zubkoff of 675138032Speter Dandelion Digital. 675238032Speter Move buffer overflow checking -- these primarily involve distrusting 675338032Speter results that may come from NIS and DNS. 675438032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 675538032Speter include <paths.h> and hence had the wrong pathnames for a few 675638032Speter things like /var/tmp. Reported by Matthew Green. 675738032Speter Conditions were reversed for the Priority: header, resulting in all 675838032Speter values being interpreted as non-urgent except for non-urgent, 675938032Speter which was interpreted as normal. Patch from Bryan Costales. 676038032Speter The -o (optional) flag was being ignored on hash and btree maps 676138032Speter since 8.7.2. Fix from Bryan Costales. 676238032Speter Content-Types listed in class "q" will always be encoded as 676338032Speter Quoted-Printable (or more accurately, will never be encoded 676438032Speter as base64). The class can have primary types (e.g., "text") 676538032Speter or full types (e.g., "text/plain"). Based on a suggestion by 676638032Speter Marius Olafsson of the University of Iceland. 676738032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 676838032Speter dialogue) so it can be passed to programs in mailers. 676938032Speter Define ${bodytype} to be the body type (from the -B flag or the 677038032Speter BODY= ESMTP parameter) so it can be passed to programs in 677138032Speter mailers. 677238032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 677338032Speter flag is set in the mailer descriptor. Suggested by John 677438032Speter Myers of CMU. 677538032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 677638032Speter The command takes a host name; data for that host is 677738032Speter immediately (and asynchronously) flushed. Because this shares 677838032Speter the -qR implementation, other hosts may be attempted, but 677938032Speter there should be no security implications. Implementation 678038032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 678138032Speter Add three new command line flags to pass in DSN parameters: -V envid 678238032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 678338032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 678438032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 678538032Speter that the -N flag applies to all recipients; there is no way 678638032Speter to specify per-address notifications on the command line, 678738032Speter nor is there an equivalent for the ORCPT= per-address 678838032Speter parameter. 678938032Speter Restore LogLevel option to be safe (it can only be increased); 679038032Speter apparently I went into paranoid mode between 8.6 and 8.7 679138032Speter and made it unsafe. Pointed out by Dabe Murphy of the 679238032Speter University of Maryland. 679338032Speter New logging on log level 15: all SMTP traffic. Patches from 679438032Speter Andrew Gross of San Diego Supercomputer Center. 679538032Speter NetInfo property value searching code wasn't stopping when it found 679638032Speter a match. This was causing the wrong values to be found (and 679738032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 679838032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 679938032Speter out by Bill Wisner of Electronics for Imaging that you can't 680038032Speter use the bracket address form for the MAIL_HUB macro, since 680138032Speter that causes the brackets to remain in the envelope recipient 680238032Speter address used for delivery. The simple fix (stripping off the 680338032Speter brackets in the config file) breaks the use of IP literal 680438032Speter addresses. This flag will solve that problem. 680538032Speter Add MustQuoteChars option. This is a list of characters that must 680638032Speter be quoted if they are found in the phrase part of an address 680738032Speter (that is, the full name part). The characters @,;:\()[] are 680838032Speter always in this list and cannot be removed. The default is 680938032Speter this list plus . and ' to match RFC 822. 681038032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 681138032Speter that do not include a host name for back compatibility with 681238032Speter some stupid SMTP clients. Setting this violates RFC 1123 681338032Speter section 5.2.5. 681438032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 681538032Speter rejecting connections if it has more than this many 681638032Speter outstanding children accepting mail. Note that you may 681738032Speter see more processes than this because of outgoing mail; this 681838032Speter is for incoming connections only. 681938032Speter Add ConnectionRateThrottle option. If set to a positive value, the 682038032Speter number of incoming SMTP connections that will be permitted 682138032Speter in a single second is limited to this number. Connections are 682238032Speter not refused during this time, just deferred. The intent is to 682338032Speter flatten out demand so that load average limiting can kick in. 682438032Speter It is less radical than MaxDaemonChildren, which will stop 682538032Speter accepting connections even if all the connections are idle 682638032Speter (e.g., due to connection caching). 682738032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 682838032Speter specifies how long cached information about the state of a 682938032Speter host will be kept before they are considered stale and the 683038032Speter host is retried. If you are using persistent host status 683138032Speter (i.e., the HostStatusDirectory option is set) this will apply 683238032Speter between runs; otherwise, it applies only within a single queue 683338032Speter run and hence is useful only for hosts that have large queues 683438032Speter that take a very long time to run. 683538032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 683638032Speter into being a single line even if they had newlines in them 683738032Speter when read. This is to get around a botch in Lotus Notes. 683838032Speter Text class maps were totally broken -- if you ever retrieved the last 683938032Speter item in a table it would be truncated. Problem noted by 684038032Speter Gregory Neil Shapiro of WPI. 684138032Speter Extend the lines printed by the mailq command (== the -bp flag) when 684238032Speter -v is given to 120 characters; this allows more information 684338032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 684438032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 684538032Speter this was treated as end-of-input. Problem noted by Bryan 684638032Speter Costales. 684738032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 684838032Speter to the queue file. Fix from John Hughes of Atlantic 684938032Speter Technologies, Inc. 685038032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 685138032Speter if this happens in a queue run it can cause nasty delays. 685238032Speter Problem noted by Mark Horton of AT&T. 685338032Speter If userdb entries pointed to userdb entries, and there were multiple 685438032Speter values for a given key, the database cursor would get 685538032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 685638032Speter of Georgia Tech. Fixed by reading all the values and creating 685738032Speter a comma-separated list; thus, the -v output will be somewhat 685838032Speter different for this case. 685938032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 686038032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 686138032Speter of Stanford University. 686238032Speter When envelopes were split due to aliases with owner- aliases, and 686338032Speter there was some error on one of the lists, more than one of 686438032Speter the owners would get the message. Problem pointed out by 686538032Speter Roy Mongiovi of Georgia Tech. 686638032Speter Detect excessive recursion in macro expansions, e.g., $X defined 686738032Speter in terms of $Y which is defined in terms of $X. Problem 686838032Speter noted by Bryan Costales; patch from Eric Wassenaar. 686938032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 687038032Speter some cases get trashed causing bogus From_ lines. Fix from 687138032Speter Kyle Jones of UUNET. 687238032Speter When doing load average initialization, if the nlist call for avenrun 687338032Speter failed, the second and subsequent lookups wouldn't notice 687438032Speter that fact causing bogus load averages to be returned. Noted 687538032Speter by Casper Dik of Sun Holland. 687638032Speter Fix problem with incompatibility with some versions of inet_aton that 687738032Speter have changed the return value to unsigned, so a check for an 687838032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 687938032Speter This could cause mail to addresses such as [foo.com] to bounce 688038032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 688138032Speter Pasteur Institute. 688238032Speter DSNs were inconsistent if a failure occurred during the DATA phase 688338032Speter rather than the RCPT phase: the Action: would be correct, but 688438032Speter the detailed status information would be wrong. Problem noted 688538032Speter by Bob Snyder of General Electric Company. 688638032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 688738032Speter that this is the initial MUA->MTA submission. The flag current 688838032Speter does nothing, but in future releases (when MUAs start using 688938032Speter these flags) it will probably turn on things like DNS 689038032Speter canonification. 689138032Speter Default end-of-line string (E= specification on mailer [M] lines) 689238032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 689338032Speter mailers. 689438032Speter Change the internal definition for the *file* and *include* mailers 689538032Speter to have $u in the argument vectors so that they aren't 689638032Speter misinterpreted as SMTP mailers and thus use \r\n line 689738032Speter termination. This will affect anyone who has redefined 689838032Speter either of these in their configuration file. 689938032Speter Don't assume that IDENT servers close the connection after a query; 690038032Speter responses can be newline terminated. From Terry Kennedy of 690138032Speter St. Peter's College. 690238032Speter Avoid core dumps on erroneous configuration files that have 690338032Speter $#mailer with nothing following. From Bryan Costales. 690438032Speter Avoid null pointer dereference with high debug values in unlockqueue. 690538032Speter Fix from Randy Martin of Clemson University. 690638032Speter Fix possible buffer overrun when expanding very large macros. Fix 690738032Speter from Kyle Jones of UUNET. 690838032Speter After 25 EXPN or VRFY commands, start pausing for a second before 690938032Speter processing each one. This avoids a certain form of denial 691038032Speter of service attack. Potential attack pointed out by Bryan 691138032Speter Costales. 691238032Speter Allow new named (not numbered!) config file rules to do validity 691338032Speter checking on SMTP arguments: check_mail for MAIL commands and 691438032Speter check_rcpt for RCPT commands. These rulesets can do anything 691538032Speter they want; their result is ignored unless they resolve to the 691638032Speter $#error mailer, in which case the indicated message is printed 691738032Speter and the command is rejected. Similarly, the check_compat 691838032Speter ruleset is called before delivery with "from_addr $| to_addr" 691938032Speter (the $| is a meta-symbol used to separate the two addresses); 692038032Speter it can give a "this sender can't send to this recipient" 692138032Speter notification. Note that this patch allows $| to stand alone 692238032Speter in rulesets. 692338032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 692438032Speter that have the name, IP address, and port number (respectively) 692538032Speter of the SMTP client (that is, the entity at the other end of 692638032Speter the connection. These can be used in (e.g.) check_rcpt to 692738032Speter verify that someone isn't trying to relay mail through your 692838032Speter host inappropriately. Be sure to use the deferred evaluation 692938032Speter form, for example $&{client_name}, to avoid having these bound 693038032Speter when sendmail reads the configuration file. 693138032Speter Add new config file rule check_relay to check the incoming connection 693238032Speter information. Like check_compat, it is passed the host name 693338032Speter and host address separated by $| and can reject connections 693438032Speter on that basis. 693538032Speter Allow IDA-style recursive function calls. Code contributed by Mark 693638032Speter Lovell and Paul Vixie. 693738032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 693838032Speter a virtual UUCP address using either a domain address or the $k 693938032Speter macro. Based on code contributed by Mark Lovell and Paul 694038032Speter Vixie. 694138032Speter Add Stanford LDAP map. Requires special libraries that are not 694238032Speter included with sendmail.

Bense 694338032Speter <bbense@networking.stanford.edu>; contact him for support. 694438032Speter See also the src/READ_ME file. 694538032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 694638032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 694738032Speter only for debugging deep bits of code where it is important to 694838032Speter distinguish between the single-character metasymbol $+ and the 694938032Speter two characters $, +. 695038032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 695138032Speter debug_dumpstate. 695238032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 695338032Speter files that are group writable are considered "unsafe" -- that 695438032Speter is, programs and files referenced from such files are not 695538032Speter valid recipients. 695638032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 695738032Speter name that was not in DNS or was a domain-literal. Problem 695838032Speter noted by Tom May. 695938032Speter Change the introduction to error messages to more clearly delineate 696038032Speter permanent from temporary failures; if both existed in a 696138032Speter single message it could be confusing. Suggested by John 696238032Speter Beck of InReference, Inc. 696338032Speter The IngoreDot (i) option didn't work for lines that were terminated 696438032Speter with CRLF. Problem noted by Ted Stockwell of Secure 696538032Speter Computing Corporation. 696638032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 696738032Speter message headers. Problem reported by Matt Dillon of Best 696838032Speter Internet Communications. 696938032Speter Check for bogus characters in the 0200-0237 range; since these are 697038032Speter used internally, very strange errors can occur if those 697138032Speter characters appear in headers. Problem noted by Anders Gertz 697238032Speter of Lysator. 697338032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 697438032Speter recipient mailer has the F=9 flag set, and only works on 697538032Speter text/plain body types. Code contributed by Marius Olafsson 697638032Speter of the University of Iceland. 697738032Speter Special case "postmaster" name so that it is always treated as lower 697838032Speter case in alias files regardless of configuration settings; 697938032Speter this prevents some potential problems where "Postmaster" or 698038032Speter "POSTMASTER" might not match "postmaster". In most cases 698138032Speter this change is a no-op. 698238032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 698338032Speter Costales. 698438032Speter The -a map flag was ignored for dequote maps. Problem noted by 698538032Speter Bryan Costales. 698638032Speter Fix core dump when a lookup of a class "prog" map returns no 698738032Speter response. Patch from Bryan Costales. 698838032Speter Log instances where sendmail is deferring or rejecting connections 698938032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 699038032Speter Include port number in process title for network daemons. Suggested 699138032Speter by Kyle Jones of UUNET. 699238032Speter Send ``double bounces'' (errors that occur when sending an error 699338032Speter message) to the address indicated in the DoubleBounceAddress 699438032Speter option (default: postmaster). Previously they were always 699538032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 699638032Speter Add new mode, -bD, that acts like -bd in all respects except that 699738032Speter it runs in foreground. This is useful for using with a 699838032Speter wrapper that "watches" system services. Suggested by Kyle 699938032Speter Jones of UUNET. 700038032Speter Fix botch in spacing around (parenthesized) comments in addresses 700138032Speter when the comment comes before the address. Patch from 700238032Speter Motonori Nakamura of Kyoto University. 700338032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 700438032Speter that are being bounced to postmaster, rather than "Returned 700538032Speter mail". This permits the person who is postmaster more 700638032Speter easily determine what messages are to their role as 700738032Speter postmaster versus bounces to mail they actually sent. Based 700838032Speter on a suggestion by Motonori Nakamura. 700938032Speter Add new value "time" for QueueSortOrder option; this causes the queue 701038032Speter to be sorted strictly by the time of submission. Note that 701143730Speter this can cause very bad behavior over slow lines (because 701238032Speter large jobs will tend to delay small jobs) and on nodes with 701338032Speter heavy traffic (because old things in the queue for hosts that 701438032Speter are down delay processing of new jobs). Also, this does not 701538032Speter guarantee that jobs will be delivered in submission order 701638032Speter unless you also set DeliveryMode=queue. In general, it should 701738032Speter probably only be used on the command line, and only in 701838032Speter conjunction with -qRhost.domain. In fact, there are very few 701938032Speter cases where it should be used at all. Based on an 702038032Speter implementation by Motonori Nakamura. 702138032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 702238032Speter the same manner as other rulesets. Previously a temporary 702338032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 702438032Speter of Stanford University. 702538032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 702638032Speter 5yz (permanent failure) code. The next MX host will still be 702738032Speter tried if the connection cannot be opened in the first place 702838032Speter or if the MAIL command returns a 4yz (temporary failure) code. 702938032Speter (It's hard to know what to do here, since neither RFC 974 nor 703038032Speter RFC 1123 specify when to proceed to the next MX host.) 703138032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 703238032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 703338032Speter This causes map lookups that get a temporary failure (e.g., 703438032Speter name server failure) to _not_ defer the delivery of the 703538032Speter message. This should only be used if your configuration file 703638032Speter is prepared to do something sensible in this case. Based on 703738032Speter an idea by Gregory Shapiro of WPI. 703838032Speter Fix problem finding network interface addresses. Patch from 703938032Speter Motonori Nakamura. 704038032Speter Don't reject qf entries that are not owned by your effective uid if 704190792Sgshapiro you are not running set-user-ID; this makes management of 704280785Sgshapiro certain kinds of firewall setups difficult. Patch 704380785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 704438032Speter Add persistent host status. This keeps the information normally 704538032Speter maintained within a single queue run in disk files that are 704638032Speter shared between sendmail instances. The HostStatusDirectory 704738032Speter is the directory in which the information is maintained. If 704838032Speter not set, persistent host status is turned off. If not a full 704938032Speter pathname, it is relative to the queue directory. A common 705038032Speter value is ".hoststat". 705138032Speter There are also two new operation modes: 705238032Speter * -bh prints the status of hosts that have had recent 705338032Speter connections. 705438032Speter * -bH purges the host statuses. No attempt is made to save 705538032Speter recent status information. 705638032Speter This feature was originally written by Paul Vixie of Vixie 705738032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 705838032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 705938032Speter with my insistence that things fit cleanly into the V8 706038032Speter framework is gratefully appreciated. 706138032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 706238032Speter operate). Avoids letting two sendmails on the local machine 706364562Sgshapiro open connections to the same remote host at the same time. 706438032Speter This reduces load on the other machine, but can cause mail to 706538032Speter be delayed (for example, if one sendmail is delivering a huge 706638032Speter message, other sendmails won't be able to send even small 706738032Speter messages). Also, it requires another file descriptor (for the 706838032Speter lock file) per connection, so you may have to reduce 706938032Speter ConnectionCacheSize to avoid running out of per-process 707038032Speter file descriptors. Based on the persistent host status code 707138032Speter contributed by Paul Vixie and Mark Lovell. 707238032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 707338032Speter SafeFileEnvironment option is set. Problem noted by Bryan 707438032Speter Costales. 707538032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 707638032Speter file. Problem noted by Bryan Costales. 707738032Speter If a job was aborted using the interrupt signal (e.g., control-C from 707838032Speter the keyboard), on some occasions an empty df file would be 707938032Speter left around; these would collect in the queue directory. 708038032Speter Problem noted by Bryan Costales. 708138032Speter Change the makesendmail script to enhance the search for Makefiles 708238032Speter based on release number. For example, on SunOS 5.5.1, it will 708338032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 708438032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 708538032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 708638032Speter Webmasters. 708738032Speter When creating maps using "newaliases", always map the keys to lower 708838032Speter case when creating the map unless the -f flag is specified on 708938032Speter the map itself. Previously this was done based on the F=u 709038032Speter flag in the local mailer, which meant you could create aliases 709138032Speter that you could never access. Problem noted by Bob Wu of DEC. 709238032Speter When a job was read from the queue, the bits causing notification on 709338032Speter failure or delay were always set. This caused those 709438032Speter notifications to be sent even if NOTIFY=NEVER had been 709538032Speter specified. Problem noted by Steve Hubert of the University 709638032Speter of Washington, Seattle. 709738032Speter Add new configurable routine validate_connection (in conf.c). This 709838032Speter lets you decide if you are willing to accept traffic from 709938032Speter this host. If it returns FALSE, all SMTP commands will return 710038032Speter "550 Access denied". -DTCPWRAPPERS will include support for 710138032Speter TCP wrappers; you will need to add -lwrap to the link line. 710238032Speter (See src/READ_ME for details.) 710338032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 710438032Speter bounces. Some people seemed to think that this could be 710538032Speter confusing (even though it is true). Suggested by Motonori 710638032Speter Nakamura. 710738032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 710838032Speter user early in processing to avoid potential security problems. 710938032Speter However, this means that all .forward and :include: files must 711038032Speter be readable by that user, and all files to be written must be 711138032Speter writable by that user and all programs will be executed by that 711238032Speter user. It is also incompatible with the SafeFileEnvironment 711338032Speter option. In other words, it may not actually add much to 711438032Speter security. However, it should be useful on firewalls and other 711538032Speter places where users don't have accounts and the aliases file is 711638032Speter well constrained. 711738032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 711838032Speter only on the first attempt to delivery to an address. It could 711938032Speter be set to be lower than Timeout.connect on the principle that 712038032Speter the mail should go through quickly to responsive hosts; less 712138032Speter responsive hosts get to wait for the next queue run. 712238032Speter Fix a problem on Solaris that occasionally causes programs 712338032Speter (such as vacation) to hang with their standard input connected 712438032Speter to a UDP port. It also created some signal handling problems. 712538032Speter The problems turned out to be an interaction between vfork(2) 712638032Speter and some of the libraries, particularly NIS/NIS+. I am 712738032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 712838032Speter Change user class map to do the same matching that actual delivery 712938032Speter will do instead of just a /etc/passwd lookup. This adds 713038032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 713138032Speter The Timeout.* options are not safe -- they can be used to create a 713238032Speter denial-of-service attack. Problem noted by Christophe 713338032Speter Wolfhugel. 713443730Speter Don't send PostmasterCopy messages in the event of a "delayed" 713538032Speter notification. Suggested by Barry Bouwsma. 713638032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 713738032Speter option is set, since this disables VERB mode.

Problem noted 714038032Speter by Motonori Nakamura of Kyoto University. 714138032Speter Only queue messages on transient .forward open failures if there 714243730Speter were no successful opens. The previous behavior caused it 714338032Speter to queue even if a "fall back" .forward was found.

Noted by David Linn of 720238032Speter Vanderbilt University. 720338032Speter Solaris changes for praliases, makemap, mailstats, and smrsh. 720438032Speter Previously you had to add -DSOLARIS in Makefile.dist; 720538032Speter this auto-detects. Based on a patch from Randall 720638032Speter Winchester of the University of Maryland. 720738032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 720838032Speter Robert La Ferla of Hot Software. 720938032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 721038032Speter (where "code" is an exit status) on domains (previously 721138032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 721238032Speter Foundation. 721338032Speter CONFIG: hooks for IPv6-style domain literals. 721438032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 721538032Speter if it is undefined the AliasFile option is never set; this 721638032Speter should be transparent for most everyone. Suggested by John 721738032Speter Myers of CMU. 721838032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 721938032Speter domain listed in $=w is masqueraded. With it, only those 722038032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 722138032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 722238032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 722338032Speter hosts under those domains as well as the domain headers 722438032Speter themselves. For example, if a configuration had 722538032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 722638032Speter foo.com would be masqueraded; with it, *.foo.com would be 722738032Speter masqueraded as well. Based on an implementation by Richard 722838032Speter (Pug) Bainter of U. Texas. 722938032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 723038032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 723138032Speter Keys are user names; values are outgoing mail addresses. Yes, 723238032Speter this does overlap with the user database, and figuring out 723338032Speter just when to use which one may be tricky. Based on code 723438032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 723538032Speter from Per Hedeland of Ericsson. 723638032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 723738032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 723838032Speter Keys are either fully qualified addresses or just the host 723938032Speter part (with the @ sign). For example, a table containing: 724038032Speter info@foo.com foo-info 724138032Speter info@bar.com bar-info 724238032Speter @baz.org jane@elsewhere.net 724338032Speter would send all mail destined for info@foo.com to foo-info 724438032Speter (which is presumably an alias), mail addressed to info@bar.com 724538032Speter to bar-info, and anything addressed to anyone at baz.org will 724638032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 724738032Speter and baz.org must all be in $=w. Based on discussions with 724838032Speter a great many people. 724938032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 725038032Speter Suggested by Richard Bainter. 725138032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 725238032Speter "fax" mailer. 725338032Speter CONFIG: allow mailertable entries to resolve to local:user; this 725438032Speter passes the original user@host in to procmail-style local 725538032Speter mailers as the "detail" information to allow them to do 725638032Speter additional clever processing. From Joe Pruett of 725738032Speter Teleport Corporation. Delivery to the original user can 725838032Speter be done by specifying "local:" (with nothing after the colon). 725938032Speter CONFIG: allow any context that takes "mailer:domain" to also take 726038032Speter "mailer:user@domain" to force mailing to the given user; 726138032Speter "local:user" can also be used to do local delivery. This 726238032Speter applies on *_RELAY and in the mailertable entries. Based 726338032Speter on a suggestion by Ribert Kiessling of Easynet. 726438032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 726538032Speter limits the possible domains; this reduces the number of DNS 726638032Speter lookups required to support this feature. For example, 726738032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 726838032Speter to domains under my.site.com. Code contributed by Anthony 726938032Speter Thyssen <anthony@cit.gu.edu.au>. 727038032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 727138032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 727238032Speter of WPI. 727338032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 727438032Speter event you have to define local mailers. Suggested by 727538032Speter Gregory Shapiro of WPI. 727638032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 727738032Speter be misinterpreted as a list:...; syntax. Based on a patch by 727838032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 727938032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 728038032Speter remotely connected. The address host!user was being 728138032Speter converted to host!user@thishost instead of host!user@uurelay. 728238032Speter Problem noted by William Gianopoulos of Raytheon Company. 728338032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 728438032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 728538032Speter "User has moved"; the former wording was confusing if the 728638032Speter new address is still on the local host. Based on a suggestion 728738032Speter by Andreas Luik. 728838032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 728938032Speter However, the class is not pre-initialized to contain root. 729038032Speter Suggested by Gregory Neil Shapiro. 729138032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 729238032Speter Wolfhugel. 729338032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 729438032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 729538032Speter well: this produces a slightly different mailbox format (no 729638032Speter Content-Length: headers), file ownerships and modes are 729738032Speter different (not owned by group mail; mode 600 instead of 660), 729838032Speter and the local mailer flags will have to be tweaked (make them 729938032Speter match bsd4.4) in order to use this mailer. Patches from Paul 730038032Speter Hammann of the Missouri Research and Education Network. 730138032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 730238032Speter was a delivery error, such as if the ownership on the file 730338032Speter was wrong or the mode changed between the initial stat and 730438032Speter the open. Problem reported by William Colburn of the New 730538032Speter Mexico Institute of Mining and Technology. 730638032Speter MAILSTATS: handle zero length files more reliably. Patch from Bryan 730738032Speter Costales. 730838032Speter MAILSTATS: add man page contributed by Keith Bostic of BSDI. 730938032Speter MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't 731038032Speter honored.

This is not exploitable from off-site. 734738032Speter Workarounds include using a unique user for the DefaultUser 734838032Speter (old u & g options) and using smrsh as the local shell. 734938032Speter SECURITY: fix some buffer overruns; in at least one case this allows 735038032Speter a local user to get root. This is not known to be exploitable 735138032Speter from off-site. The workaround is to disable chfn(1) commands. 735238032Speter 735364562Sgshapiro8.7.5/8.7.3 1996/03/04 735438032Speter Fix glitch in 8.7.4 when putting certain internal lines; this can 735538032Speter in some case cause connections to hang or messages to have 735638032Speter extra spaces in odd places. Patch from Eric Wassenaar; 735738032Speter reports from Eric Hall of Chiron Corporation, Stephen 735838032Speter Hansen of Stanford University, Dean Gaudet of HotWired, 735938032Speter and others. 736038032Speter 736164562Sgshapiro8.7.4/8.7.3 1996/02/18 736238032Speter SECURITY: In some cases it was still possible for an attacker to 736338032Speter insert newlines into a queue file, thus allowing access to 736438032Speter any user (except root). 736538032Speter CONFIG: no changes -- it is not a bug that the configuration 736638032Speter version number is unchanged. 736738032Speter 736864562Sgshapiro8.7.3/8.7.3 1995/12/03 736938032Speter Fix botch in name server timeout in RCPT code; this problem caused 737038032Speter two responses in SMTP, which breaks things horribly. Fix 737138032Speter from Gregory Neil Shapiro of WPI. 737238032Speter Verify that L= value on M lines cannot be negative, which could cause 737338032Speter negative array subscripting. Not a security problem since 737438032Speter this has to be in the config file, but it could have caused 737538032Speter core dumps. Pointed out by Bryan Costales. 737638032Speter Fix -d21 debug output for long macro names. Pointed out by Bryan 737738032Speter Costales. 737838032Speter PORTABILITY FIXES: 737938032Speter SCO doesn't have ftruncate. From Bill Aten of Computerizers. 738038032Speter IBM's version of arpa/nameser.h defaults to the wrong byte 738138032Speter order. Tweak it to work properly. Based on fixes 738238032Speter from Fletcher Mattox of UTexas and Betty Lee of 738338032Speter Stanford University. 738438032Speter CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option. 738538032Speter Deficiency pointed out by Bryan Costales of ICSI. 738638032Speter 738764562Sgshapiro8.7.2/8.7.2 1995/11/19 738838032Speter REALLY fix the backslash escapes in SmtpGreetingMessage, 738938032Speter OperatorChars, and UnixFromLine options. They were not 739038032Speter properly repaired in 8.7.1. 739138032Speter Completely delete the Bcc: header if and only if there are other 739238032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 739338032Speter last being a historic botch, of course). If Bcc: is the 739438032Speter only recipient header in the message, its value is tossed, 739543730Speter but the header name is kept. The old behavior (always keep 739638032Speter the header name and toss the value) allowed primary recipients 739738032Speter to see that a Bcc: went to _someone_. 739838032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 739938032Speter sender to <address> using -f'' syslog messages. Suggested 740038032Speter by Kari Hurtta. 740138032Speter If a sequence or switch map lookup entry gets a tempfail but then 740238032Speter continues on to another map type, but the name is not found, 740338032Speter return a temporary failure from the sequence or switch map. 740438032Speter For example, if hosts search ``dns files'' and DNS fails 740538032Speter with a tempfail, the hosts map will go on and search files, 740638032Speter but if it fails the whole thing should be a tempfail, not 740738032Speter a permanent (host unknown) failure, even though that is the 740838032Speter failure in the hosts.files map. This error caused hard 740938032Speter bounces when it should have requeued. 741038032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 741190792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 741238032Speter working properly due to excessive paranoia. Pointed out by 741338032Speter John Hawkinson of Panix. 741438032Speter An SMTP RCPT command referencing a host that gave a nameserver 741538032Speter timeout would return a 451 command (8.6 accepted it and 741643730Speter queued it locally). Revert to the 8.6 behavior in order 741738032Speter to simplify queue management for clustered systems. Suggested 741838032Speter by Gregory Neil Shapiro of WPI. The same problem could break 741938032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 742038032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 742138032Speter Infobiogen. 742238032Speter Fix possible buffer overflow in munchstring(). This was not a security 742338032Speter problem because you couldn't specify any argument to this 742438032Speter without first giving up root privileges, but it is still a 742538032Speter good idea to avoid future problems. Problem noted by John 742638032Speter Hawkinson and Sam Hartman of MIT. 742738032Speter ``452 Out of disk space for temp file'' messages weren't being 742838032Speter printed. Fix from David Perlin of Nanosoft. 742943730Speter Don't advertise the ESMTP DSN extension if the SendMimeErrors option 743038032Speter is not set, since this is required to get the actual DSNs 743138032Speter created. Problem pointed out by John Gardiner Myers of CMU. 743238032Speter Log permission problems that cause .forward and :include: files to 743338032Speter be untrusted or ignored on log level 12 and higher. Suggested 743438032Speter by Randy Martin of Clemson University. 743538032Speter Allow user ids in U= clauses of M lines to have hyphens and 743638032Speter underscores. 743738032Speter Fix overcounting of recipients -- only happened when sending to an 743838032Speter alias. Pointed out by Mark Andrews of SGI and Jack Woolley 743938032Speter of Systems and Computer Technology Corporation. 744038032Speter If a message is sent to an address that fails, the error message that 744138032Speter is returned could show some extraneous "success" information 744238032Speter included even if the user did not request success notification, 744338032Speter which was confusing. Pointed out by Allan Johannesen of WPI. 744438032Speter Config files that had no AliasFile definition were defaulting to 744538032Speter using /etc/aliases; this caused problems with nullclient 744638032Speter configurations. Change it back to the 8.6 semantics of 744738032Speter having no local alias file unless it is declared. Problem 744838032Speter noted by Charles Karney of Princeton University. 744938032Speter Fix compile problem if NOTUNIX is defined. Pointed out by Bryan 745038032Speter Costales of ICSI. 745138032Speter Map lookups of class "userdb" maps were always case sensitive; they 745238032Speter should be controlled by the -f flag like other maps.

Patch from Booker C. Bense of Stanford 747538032Speter University. 747638032Speter Queue run processes would re-spawn daemons when given a SIGHUP; only 747738032Speter the parent should do this. Fix from Brian Coan of the 747838032Speter Association for Progressive Communications. 747938032Speter If MinQueueAge was set and a message was considered but not run 748038032Speter during a queue run and the Timeout.queuereturn interval was 748138032Speter reached, a "timed out" error message would be returned that 748238032Speter didn't include the failed address (and claimed to be a warning 748338032Speter even though it was fatal). The fix is to not return such 748438032Speter messages until they are actually tried, i.e., in the next 748538032Speter MinQueueAge interval. Problem noted by Rein Tollevik of 748638032Speter SINTEF RUNIT, Oslo. 748738032Speter Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions 748838032Speter that have the hes_getmailhost() routine.

Pointed 750538032Speter out by Richard Allen of the University of Iceland. 750638032Speter Also, use -Aa -D_HPUX_SOURCE instead of -Ae, which 750738032Speter isn't supported on all compilers. 750838032Speter UXPDS: compilation fixes from Diego R. Lopez. 750938032Speter CONFIG: FAX mailer wasn't setting .FAX as a pseudo-domain unless 751038032Speter you also had a FAX_RELAY.

Previously it worked differently 752338032Speter for different files. 752438032Speter CONFIG: Change relay mailer to do masquerading like 8.6 did. My take 752538032Speter is that this is wrong, but the change was causing problems 752638032Speter for some people. From Per Hedeland of Ericsson. 752738032Speter CONTRIB: bitdomain.c patch from John Gardiner Myers <jgm+@CMU.EDU>; 752838032Speter portability changes for Posix environments (no functional 752938032Speter changes). 753038032Speter 753164562Sgshapiro8.7.1/8.7.1 1995/10/01 753238032Speter Old macros that have become options (SmtpGreetingMessage, 753338032Speter OperatorChars, and UnixFromLine) didn't allow backslash 753438032Speter escapes in the options, where they previously had. Bug 753538032Speter pointed out by John Hawkinson of MIT. 753638032Speter Fix strange case of an executable called by a program map that 753738032Speter returns a value but also a non-zero exit status; this 753838032Speter would give contradictory results in the higher level; in 753938032Speter particular, the default clause in the map lookup would be 754038032Speter ignored. Change to ignore the value if the program returns 754138032Speter non-zero exit status. From Tom Moore of AT&T GIS. 754238032Speter Shorten parameters passed to syslog() in some contexts to avoid a 754338032Speter bug in many vendors' implementations of that routine. Although 754438032Speter this isn't really a bug in sendmail per se, and my solution 754538032Speter has to assume that syslog() has at least a 1K buffer size 754638032Speter internally (I know some vendors have shortened this 754738032Speter dramatically -- they're on their own), sendmail is a popular 754838032Speter target. Also, limit the size of %s arguments in sprintf. 754938032Speter These both have possible security implications. Solutions 755038032Speter suggested by Casper Dik of Sun's Network Security Group 755138032Speter (Holland), Mark Seiden, and others. 755238032Speter Fix a problem that might cause a non-standard -B (body type) 755338032Speter parameter to be passed to the next server with undefined 755438032Speter results. This could have security implications. 755538032Speter If a filesystem was at > 100% utilization, the freediskspace() 755638032Speter routine incorrectly returned an error rather than zero. 755738032Speter Problem noted by G. Paul Ziemba of Alantec. 755838032Speter Change MX sort order so that local hostnames (those in $=w) always 755938032Speter sort first within a given preference. This forces the bestmx 756038032Speter map to always return the local host first, if it is included 756138032Speter in the list of highest priority MX records. From K. Robert 756238032Speter Elz. 756338032Speter Avoid some possible null pointer dereferences. Fixes from Randy 756438032Speter Martin <WOLF@CLEMSON.EDU> 756538032Speter When sendmail starts up on systems that have no fully qualified 756638032Speter domain name (FQDN) anywhere in the first matching host map 756738032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 756838032Speter sendmail would sleep to try to find a FQDN, which it really 756938032Speter really needs. This has been changed to fall through to the 757038032Speter next map type if it can't find a FQDN -- i.e., if the hosts 757138032Speter file doesn't have a FQDN, it will try dns even though the 757238032Speter short name was found in /etc/hosts. This is probably a crock, 757338032Speter but many people have hosts files without FQDNs. Remember: 757438032Speter domain names are your friends. 757538032Speter Log a high-priority message if you can't find your FQDN during startup. 757638032Speter Suggested by Simon Barnes of Schlumberger Limited. 757738032Speter When using Hesiod, initialize it early to improve error reporting. 757838032Speter Patch from Don Lewis of Silicon Systems, Inc. 757938032Speter Apparently at least some versions of Linux have a 90 !minute! TCP 758038032Speter connection timeout in the kernel. Add a new "connect" timeout 758138032Speter to limit this time. Defaults to zero (use whatever the 758238032Speter kernel provides). Based on code contributed by J.R. Oldroyd 758338032Speter of TerraNet. 758438032Speter Under some circumstances, a failed message would not be properly 758538032Speter removed from the queue, causing tons of bogus error messages. 758638032Speter (This fix eliminates the problematic EF_KEEPQUEUE flag.) 758738032Speter Problem noted by Allan E Johannesen and Gregory Neil Shapiro 758838032Speter of WPI. 758938032Speter PORTABILITY FIXES: 759038032Speter On IRIX 5.x, there was an inconsistency in the setting 759138032Speter of sendmail.st location.

Suggested by Per Hedeland of Ericsson. 760738032Speter CONFIG: local mailer on Solaris 2 should always get a -f flag because 760838032Speter otherwise the F=S causes the From_ line to imply that root is 760938032Speter the sender. Problem pointed out by Claude Scarpelli of 761038032Speter Infobiogen (France). 761138032Speter NEW FILES: 761238032Speter cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) 761338032Speter src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) 761438032Speter src/Makefiles/Makefile.UXPDS 761538032Speter 761664562Sgshapiro8.7/8.7 1995/09/16 761738032Speter Fix a problem that could cause sendmail to run out of file 761838032Speter descriptors due to a trashed data structure after a 761938032Speter vfork. Fix from Brian Coan of the Institute for 762038032Speter Global Communications. 762138032Speter Change the VRFY response if you have disabled VRFY -- some 762238032Speter people seemed to think that it was too rude. 762338032Speter Avoid reference to uninitialized file descriptor if HASFLOCK 762438032Speter was not defined. This was used "safely" in the sense 762538032Speter that it only did a stat, but it would have set the 762638032Speter map modification time improperly. Problem pointed out 762738032Speter by Roy Mongiovi of Georgia Tech. 762838032Speter Clean up the Subject: line on warning messages and return 762938032Speter receipts so that they don't say "Returned mail:"; this 763038032Speter can be confusing. 763138032Speter Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is 763238032Speter useful enough to make it worthwhile printing on "-d". 763338032Speter Avoid logging alias statistics every time you read the alias 763438032Speter file on systems with no database method compiled in. 763538032Speter If you have a name with a trailing dot, and you try looking it 763638032Speter up using gethostbyname without the dot (for /etc/hosts 763738032Speter compatibility), be sure to turn off RES_DEFNAMES and 763838032Speter RES_DNSRCH to avoid finding the wrong name accidentally. 763938032Speter Problem noted by Charles Amos of the University of 764038032Speter Maryland. 764138032Speter Don't do timeouts in collect if you are not running SMTP. 764238032Speter There is nothing that says you can't have a long 764338032Speter running program piped into sendmail (possibly via 764438032Speter /bin/mail, which just execs sendmail). Problem reported 764538032Speter by Don "Truck" Lewis of Silicon Systems. 764638032Speter Try gethostbyname() even if the DNS lookup fails iff option I 764738032Speter is not set. This allows you to have hosts listed in 764838032Speter NIS or /etc/hosts that are not known to DNS. It's normally 764938032Speter a bad idea, but can be useful on firewall machines. This 765038032Speter should really be broken out on a separate flag, I suppose. 765138032Speter Avoid compile warnings against BIND 4.9.3, which uses function 765238032Speter prototypes.

From Kyle Jones of UUNET. 765738032Speter SECURITY: avoid denial-of-service attacks possible by destroying 765838032Speter the alias database file by setting resource limits low. 765938032Speter This involves adding two new compile-time options: 766038032Speter HASSETRLIMIT (indicating that setrlimit(2) support is 766138032Speter available) and HASULIMIT (indicating that ulimit(2) support 766238032Speter is available -- the Release 3 form is used). The former 766338032Speter is assumed on BSD-based systems, the latter on System 766438032Speter V-based systems. Attack noted by Phil Brandenberger of 766538032Speter Swarthmore University. 766638032Speter New syntaxes in test (-bt) mode: 766738032Speter ``.Dmvalue'' will define macro "m" to "value". 766838032Speter ``.Ccvalue'' will add "value" to class "c". 766938032Speter ``=Sruleset'' will dump the contents of the indicated 767038032Speter ruleset. 767138032Speter ``=M'' will display the known mailers. 767238032Speter ``-ddebug-spec'' is equivalent to the command-line 767338032Speter -d debug flag. 767438032Speter ``$m'' will print the value of macro $m. 767538032Speter ``$=c'' will print the contents of class $=c. 767638032Speter ``/mx host'' returns the MX records for ``host''. 767738032Speter ``/parse address'' will parse address, returning the value of 767838032Speter crackaddr (essentially, the comment information) 767938032Speter and the parsed address. 768038032Speter ``/try mailer address'' will rewrite address into the form 768138032Speter it will have when presented to the indicated mailer. 768238032Speter ``/tryflags flags'' will set flags used by parsing. The 768338032Speter flags can be `H' for header or `E' for envelope, 768438032Speter and `S' for sender or `R' for recipient. These 768538032Speter can be combined, so `HR' sets flags for header 768638032Speter recipients. 768738032Speter ``/canon hostname'' will try to canonify hostname and 768838032Speter return the result. 768938032Speter ``/map mapname key'' will look up `key' in the indicated 769038032Speter `mapname' and return the result. 769138032Speter Somewhat better handling of UNIX-domain socket addresses -- it 769238032Speter should show the pathname rather than hex bytes. 769338032Speter Restore ``-ba'' mode -- this reads a file from stdin and parses 769438032Speter the header for envelope sender information and uses 769538032Speter CR-LF as message terminators. It was thought to be 769638032Speter obsolete (used only for Arpanet NCP protocols), but it 769738032Speter turns out that the UK ``Grey Book'' protocols require 769838032Speter that functionality. 769938032Speter Fix a fix in previous release -- if gethostname and gethostbyname 770038032Speter return a name without dots, and if an attempt to canonify 770138032Speter that name fails, wait one minute and try again. This can 770238032Speter result in an extra 60 second delay on startup if your system 770338032Speter hostname (as returned by hostname(1)) has no dot and no names 770438032Speter listed in /etc/hosts or your NIS map have a dot. 770538032Speter Check for proper domain name on HELO and EHLO commands per 770638032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 770738032Speter of Michigan Technological University. 770838032Speter Relax chownsafe rules slightly -- old version said that if you 770938032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 771038032Speter if fpathconf returned EINVAL or ENOSYS), assume that 771138032Speter chown is not safe. The new version falls back to whether 771238032Speter you are on a BSD system or not. This is important for 771338032Speter SunOS, which apparently always returns one of those 771438032Speter error codes. This impacts whether you can mail to files 771538032Speter or not. 771638032Speter Syntax errors such as unbalanced parentheses in the configuration 771738032Speter file could be omitted if you had "Oem" prior to the 771838032Speter syntax error in the config file. Change to always print 771938032Speter the error message. It was especially weird because it 772038032Speter would cause a "warning" message to be sent to the Postmaster 772138032Speter for every message sent (but with no transcript). Problem 772238032Speter noted by Gregory Paris of Motorola. 772338032Speter Rewrite collect and putbody to handle full 8-bit data, including 772438032Speter zero bytes. These changes are internally extensive, but 772538032Speter should have minimal impact on external function. 772638032Speter Allow full words for option names -- if the option letter is 772738032Speter (apparently) a space, then take the word following -- e.g., 772838032Speter O MatchGECOS=TRUE 772938032Speter The full list of old and new names is as follows: 773038032Speter 7 SevenBitInput 773138032Speter 8 EightBitMode 773238032Speter A AliasFile 773338032Speter a AliasWait 773438032Speter B BlankSub 773538032Speter b MinFreeBlocks/MaxMessageSize 773638032Speter C CheckpointInterval 773738032Speter c HoldExpensive 773838032Speter D AutoRebuildAliases 773938032Speter d DeliveryMode 774038032Speter E ErrorHeader 774138032Speter e ErrorMode 774238032Speter f SaveFromLine 774338032Speter F TempFileMode 774438032Speter G MatchGECOS 774538032Speter H HelpFile 774638032Speter h MaxHopCount 774738032Speter i IgnoreDots 774838032Speter I ResolverOptions 774938032Speter J ForwardPath 775038032Speter j SendMimeErrors 775138032Speter k ConnectionCacheSize 775238032Speter K ConnectionCacheTimeout 775338032Speter L LogLevel 775438032Speter l UseErrorsTo 775538032Speter m MeToo 775638032Speter n CheckAliases 775738032Speter O DaemonPortOptions 775838032Speter o OldStyleHeaders 775938032Speter P PostmasterCopy 776038032Speter p PrivacyOptions 776138032Speter Q QueueDirectory 776238032Speter q QueueFactor 776338032Speter R DontPruneRoutes 776438032Speter r, T Timeout 776538032Speter S StatusFile 776638032Speter s SuperSafe 776738032Speter t TimeZoneSpec 776838032Speter u DefaultUser 776938032Speter U UserDatabaseSpec 777043730Speter V FallbackMXHost 777138032Speter v Verbose 777238032Speter w TryNullMXList 777338032Speter x QueueLA 777438032Speter X RefuseLA 777538032Speter Y ForkEachJob 777638032Speter y RecipientFactor 777738032Speter z ClassFactor 777838032Speter Z RetryFactor 777938032Speter The old macros that passed information into sendmail have 778038032Speter been changed to options; those correspondences are: 778138032Speter $e SmtpGreetingMessage 778238032Speter $l UnixFromLine 778338032Speter $o OperatorChars 778438032Speter $q (deleted -- not necessary) 778538032Speter To avoid possible problems with an older sendmail, 778638032Speter configuration level 6 is accepted by this version of 778738032Speter sendmail; any config file using the new names should 778838032Speter specify "V6" in the configuration. 778938032Speter Change address parsing to properly note that a phrase before a 779038032Speter colon and a trailing semicolon are essentially the same 779138032Speter as text outside of angle brackets (i.e., sendmail should 779238032Speter treat them as comments). This is to handle the 779338032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 779438032Speter assume that ``group name:'' is a comment on the first 779538032Speter address and the ``;'' is a comment on the last address). 779638032Speter This requires config file support to get right. It does 779738032Speter understand that :: is NOT this syntax, and can be turned 779838032Speter off completely by setting the ColonOkInAddresses option. 779938032Speter Level 6 config files added with new mailer flags: 780038032Speter A Addresses are aliasable. 780138032Speter i Do udb rewriting on envelope as well as header 780238032Speter sender lines. Applies to the from address mailer 780338032Speter flags rather than the recipient mailer flags. 780438032Speter j Do udb rewriting on header recipient addresses. 780538032Speter Applies to the sender mailer flags rather than the 780638032Speter recipient mailer flags. 780738032Speter k Disable check for loops when doing HELO command. 780838032Speter o Always run as the mail recipient, even on local 780938032Speter delivery. 781038032Speter w Check for an /etc/passwd entry for this user. 781138032Speter 5 Pass addresses through ruleset 5. 781238032Speter : Check for :include: on this address. 781338032Speter | Check for |program on this address. 781438032Speter / Check for /file on this address. 781538032Speter @ Look up sender header addresses in the user 781638032Speter database. Applies to the mailer flags for the 781738032Speter mailer corresponding to the envelope sender 781838032Speter address, rather than to recipient mailer flags. 781938032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 782038032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 782138032Speter mailers, and the ColonOkInAddresses option. 782238032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 782338032Speter John Beck of Hewlett-Packard, who generously contributed 782438032Speter their implementation to me, which I then didn't use (see 782538032Speter mime.c for an explanation of why). This adds the 782638032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 782738032Speter to control handling of 8-bit data. These have to cope with 782838032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 782938032Speter 8-bit data that is entered without declaring it as 8-bit 783038032Speter MIME -- technically this is illegal according to the 783138032Speter specs) and labelled 8-bit data (that is, it was declared 783238032Speter as 8BITMIME in the ESMTP session or by using the 783338032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 783438032Speter set then 8-bit data is sent to non-8BITMIME machines 783538032Speter instead of converting to 7 bit (essentially using 783638032Speter just-send-8 semantics). The values for EightBitMode are: 783738032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 783838032Speter any necessary conversion of 8BITMIME to 7BIT 783938032Speter (essentially, the full MIME option). 784038032Speter p pass unlabelled 8-bit input, but convert labelled 784138032Speter 8BITMIME input to 7BIT as required (default). 784238032Speter s strict adherence: reject unlabelled 8-bit input, 784338032Speter convert 8BITMIME to 7BIT as required. The F=8 784438032Speter flag is ignored. 784538032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 784638032Speter the setting of F=8. 784738032Speter Add new internal class 'n', which is the set of MIME Content-Types 784838032Speter which can not be 8 to 7 bit encoded because of other 784938032Speter considerations. Types "multipart/*" and "message/*" are 785038032Speter never directly encoded (although their components can be). 785138032Speter Add new internal class 's', which is the set of subtypes of the 785238032Speter MIME message/* content type that can be treated as though 785338032Speter they are an RFC822 message. It is predefined to have 785438032Speter "rfc822". Suggested By Kari Hurtta. 785538032Speter Add new internal class 'e'. This is the set of MIME 785638032Speter Content-Transfer-Encodings that can be converted to 785738032Speter a seven bit format (Quoted-Printable or Base64). It is 785838032Speter preinitialized to contain "7bit", "8bit", and "binary". 785938032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 786038032Speter short name) to set the default character set to use in the 786138032Speter Content-Type: header when doing encoding of an 8-bit message 786238032Speter which isn't marked as MIME into MIME format. If the C= 786338032Speter parameter is set on the Envelope From address, use that as 786438032Speter the default encoding; else use the DefaultCharSet option. 786538032Speter If neither is set, it defaults to "unknown-8bit" as 786638032Speter suggested by RFC 1428 section 3. 786738032Speter Allow ``U=user:group'' field in mailer definition to set a default 786838032Speter user and group that a mailer will be executed as. This 786938032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 787038032Speter also set, it is the uid/gid that will always be used (that 787138032Speter is, the controlling address is ignored). The values may be 787238032Speter numeric or symbolic; if only a symbolic user is given (no 787338032Speter group) that user's default group in the passwd file is used 787438032Speter as the group. Based on code donated by Chip Rosenthal of 787538032Speter Unicom. 787638032Speter Allow `u' option to also accept user:group as a value, in the same 787738032Speter fashion as the U= mailer option. 787838032Speter Add the symbolic time zone name in the Arpanet format dates (as 787938032Speter a comment). This adds a new compile-time configuration 788038032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 788138032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 788238032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 788338032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 788438032Speter timezone()), or TZ_NONE (don't include the comment). Code 788538032Speter from Chip Rosenthal. 788638032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 788738032Speter For example, 788838032Speter O Timeout.helo = 2m 788938032Speter There are also two new suboptions "queuereturn" and 789038032Speter "queuewarn"; these subsume the old T option. Thus, to 789138032Speter set them both the preferred new syntax is 789238032Speter O Timeout.queuereturn = 5d 789338032Speter O Timeout.queuewarn = 4h 789438032Speter Sort queue by host name instead of by message priority if the 789538032Speter QueueSortOrder option (no short name) is set is set to 789638032Speter ``host''. This makes better use of the connection cache, 789738032Speter but may delay more ``interactive'' messages behind large 789838032Speter backlogs under some circumstances. This is probably a 789938032Speter good option if you have high speed links or don't do lots 790038032Speter of ``batch'' messages, but less good if you are using 790138032Speter something like PPP on a 14.4 modem. Based on code 790238032Speter contributed by Roy Mongiovi of Georgia Tech (my main 790338032Speter contribution was to make it configurable). 790438032Speter Save i-number of df file in qf file to simplify rebuilding of queue 790538032Speter after disastrous disk crash. Suggested by Kyle Jones of 790638032Speter UUNET; closely based on code from KJS DECWRL code written 790738032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 790838032Speter are NOT back compatible with 8.6 -- that is, you can convert 790938032Speter from 8.6 to 8.7, but not the other direction. 791038032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 791138032Speter route-addrs in envelopes; this is because in some cases 791238032Speter they can be sent to the shell, which interprets them as 791338032Speter I/O redirection. 791438032Speter Don't include error file (option E) with return-receipts; this 791538032Speter can be confusing. 791638032Speter Don't send "Warning: cannot send" messages to owner-* or 791738032Speter *-request addresses. Suggested by Christophe Wolfhugel 791838032Speter of the Institut Pasteur, Paris. 791938032Speter Allow -O command line flag to set long form options. 792038032Speter Add "MinQueueAge" option to set the minimum time between attempts 792138032Speter to run the queue. For example, if the queue interval 792238032Speter (-q value) is five minutes, but the minimum queue age 792338032Speter is fifteen minutes, jobs won't be tried more often than 792438032Speter once every fifteen minutes. This can be used to give 792538032Speter you more responsiveness if your delivery mode is set to 792638032Speter queue-only. 792738032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 792838032Speter :include: and .forward files. 792938032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 793038032Speter key field name, the value field name, and the field 793138032Speter delimiter. The field delimiter can be a single character 793238032Speter or the sequence "\t" or "\n" for tab or newline. 793338032Speter These are for use by NIS+ and similar access methods. 793438032Speter Change maps to always strip quotes before lookups; the -q flag 793543730Speter turns off this behavior. Suggested by Motonori Nakamura. 793638032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 793738032Speter key and value field names respectively. Code donated by 793838032Speter Sun Microsystems. 793938032Speter Add "hesiod" map class. The "file name" is used as the 794038032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 794138032Speter first value found for the match. Code donated by Scott 794238032Speter Hutton of Indiana University. 794338032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 794438032Speter specify the name of the property that is searched as the 794538032Speter key and a -v flag to specify the name of the property that 794638032Speter is returned as the value (defaults to "members"). The 794738032Speter default map is "/aliases". Some code based on code 794838032Speter contributed by Robert La Ferla of Hot Software. 794938032Speter Add "text" map class. This does slow, linear searches through 795038032Speter text files. The -z flag specifies a column delimiter 795138032Speter (defaults to any sequence of white space), the -k flag 795238032Speter sets the key column number, and the -v flag sets the 795338032Speter value column number. Lines beginning with `#' are treated 795438032Speter as comments. 795538032Speter Add "program" map class to execute arbitrary programs. The search 795638032Speter key is presented as the last argument; the output is one 795738032Speter line read from the programs standard output. Exit statuses 795838032Speter are from sysexits.h. 795938032Speter Add "sequence" map class -- searches maps in sequence until it 796038032Speter finds a match. For example, the declarations: 796138032Speter Kmap1 ... 796238032Speter Kmap2 ... 796338032Speter Kmapseq sequence map1 map2 796438032Speter defines a map "mapseq" that first searches map1; if the 796538032Speter value is found it is returned immediately, otherwise 796638032Speter map2 is searched and the value returned. 796738032Speter Add "switch" map class. This is much like "sequence" except that 796838032Speter the ordering is fetched from an external file, usually 796938032Speter the system service switch. The parameter is the name of 797038032Speter the service to switch on, and the maps that it will use 797138032Speter are the name of the switch map followed by ".service_type". 797238032Speter For example, if the declaration of the map is 797338032Speter Ksample switch hosts 797438032Speter and the system service switch specifies that hosts are 797538032Speter looked up using dns and nis in that order, then this is 797638032Speter equivalent to 797738032Speter Ksample sequence sample.dns sample.nis 797838032Speter The subordinate maps (sample.*) must already be defined. 797938032Speter Add "user" map class -- looks up users using getpwnam. Takes a 798038032Speter "-v field" flag on the definition that tells what passwd 798138032Speter entry to return -- legal values are name, passwd, uid, gid, 798238032Speter gecos, dir, and shell. Generally expected to be used with 798338032Speter the -m (matchonly) flag. 798438032Speter Add "bestmx" map class -- returns the best MX value for the host 798538032Speter listed as the value. If there are several "best" MX records 798638032Speter for this host, one will be chosen at random. 798738032Speter Add "userdb" map class -- looks up entries in the user database. 798838032Speter The "file name" is actually the tag that will be used, 798938032Speter typically "mailname". If there are multiple entries 799038032Speter matching the name, the one chosen is undefined. 799138032Speter Add multiple queue timeouts (both return and warning). These are 799238032Speter set by the Precedence: or Priority: header fields to one of 799338032Speter three values. If a Priority: is set and has value "normal", 799464562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 799538032Speter used. If no priority is set, the Precedence: is consulted; 799638032Speter if negative, non-urgent timeouts are used; if greater than 799738032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 799838032Speter are used. The timeouts are set by setting the six timeouts 799938032Speter queue{warn,return}.{urgent,normal,non-urgent}. 800038032Speter Fix problem when a mail address is resolved to a $#error mailer 800138032Speter with a temporary failure indication; it works in SMTP, 800238032Speter but when delivering locally the mail is silently discarded. 800338032Speter This patch, from Kyle Jones of UUNET, bounces it instead 800438032Speter of queueing it (queueing is very hard). 800538032Speter When using /etc/hosts or NIS-style lookups, don't assume that 800638032Speter the first name in the list is the best one -- instead, 800738032Speter search for the first one with a dot. For example, if 800838032Speter an /etc/hosts entry reads 800938032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 801038032Speter this change will use the second name as the canonical 801138032Speter machine name instead of the initial, unqualified name. 801238032Speter Change dequote map to replace spaces in quoted text with a value 801338032Speter indicated by the -s flag on the dequote map definition. 801438032Speter For example, ``Mdequote dequote -s_'' will change 801538032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 801638032Speter quoted (because of the space character). Suggested by Dan 801738032Speter Oscarsson for use in X.400 addresses. 801838032Speter Implement long macro names as ${name}; long class names can 801938032Speter be similarly referenced as $={name} and $~{name}. 802038032Speter Definitions are (e.g.) ``D{name}value''. Names that have 802138032Speter a leading lower case letter or punctuation characters are 802238032Speter reserved for internal use by sendmail; i.e., config files 802338032Speter should use names that begin with a capital letter. Based 802438032Speter on code contributed by Dan Oscarsson. 802538032Speter Fix core dump if getgrgid returns a null group list (as opposed 802638032Speter to an empty group list, that is, a pointer to a list 802738032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 802838032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 802938032Speter failed, it called syserr which called newstr which called 803038032Speter xalloc.... The newstr is now avoided for "panic" messages. 803138032Speter Reported by Stuart Kemp of James Cook University. 803238032Speter Improve connection cache timeouts; previously, they were not even 803338032Speter checked if you were delivering to anything other than an 803438032Speter IPC-connected host, so a series of (say) local mail 803538032Speter deliveries could cause cached connections to be open 803638032Speter much longer than the specified timeout. 803738032Speter If an incoming message exceeds the maximum message size, stop 803838032Speter writing the incoming bytes to the queue data file, since 803938032Speter this can fill your mqueue partition -- this is a possible 804038032Speter denial-of-service attack. 804138032Speter Don't reject all numeric local user names unless HESIOD is 804238032Speter defined. It turns out that Posix allows all-numeric 804338032Speter user names. Fix from Tony Sanders of BSDI. 804438032Speter Add service switch support. If the local OS has a service 804538032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 804638032Speter on DEC systems) that will be used; otherwise, it falls back 804738032Speter to using a local mechanism based on the ServiceSwitchFile 804838032Speter option (default: /etc/service.switch). For example, if the 804938032Speter service switch lists "files" and "nis" for the aliases 805038032Speter service, that will be the default lookup order. the "files" 805138032Speter ("local" on DEC) service type expands to any alias files 805238032Speter you listed in the configuration file, even if they aren't 805338032Speter actually file lookups. 805438032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 805538032Speter variable which tells whether or not DNS should be considered 805638032Speter canonical. This is now determined based on whether or not 805738032Speter "dns" is in the service list for "hosts". 805838032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 805938032Speter Status Notifications). DSN notifications override 806038032Speter Return-Receipt-To: headers, which are bogus anyhow -- 806138032Speter support for them has been removed. 806238032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 806338032Speter definitions to define the types used in DSN returns for 806438032Speter MTA names, addresses, and diagnostics respectively. 806538032Speter Extend heuristic to force running in ESMTP mode to look for the 806638032Speter five-character string "ESMTP" anywhere in the 220 greeting 806738032Speter message (not just the second line). This is to provide 806838032Speter better compatibility with other ESMTP servers. 806938032Speter Print sequence number of job when running the queue so you can 807038032Speter easily see how much progress you have made. Suggested 807138032Speter by Peter Wemm of DIALix. 807238032Speter Map newlines to spaces in logged message-ids; some versions of 807338032Speter syslog truncate the rest of the line after newlines. 807438032Speter Suggested by Fletcher Mattox of U. Texas. 807538032Speter Move up forking for job runs so that if a message is split into 807638032Speter multiple envelopes you don't get "fork storms" -- this 807738032Speter also improves the connection cache utilization. 807838032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 807938032Speter the purposes of refusing to send error returns. Suggested 808038032Speter by Motonori Nakamura of Ritsumeikan University. 808138032Speter Relax rules on when a file can be written when referenced from 808238032Speter the aliases file: use the default uid/gid instead of the 808338032Speter real uid/gid. This allows you to create a file owned by 808438032Speter and writable only by the default uid/gid that will work 808590792Sgshapiro all the time (without having the set-user-ID bit set). Change 808638032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 808738032Speter Microsystems. 808838032Speter Add "DialDelay" option (no short name) to provide an "extra" 808938032Speter delay for dial on demand systems. If this is non-zero 809038032Speter and a connect fails, sendmail will wait this long and 809138032Speter then try again. If it takes longer than the kernel 809238032Speter timeout interval to establish the connection, this 809338032Speter option can give the network software time to establish 809438032Speter the link. The default units are seconds. 809538032Speter Move logging of sender information to be as early as possible; 809638032Speter previously, it could be delayed a while for SMTP mail 809738032Speter sent to aliases. Suggested by Brad Knowles of the 809838032Speter Defense Information Systems Agency. 809938032Speter Call res_init() before setting RES_DEBUG; this is required by 810038032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 810138032Speter the National Computer Security Center. 810238032Speter Add xdelay= field in logs -- this is a transaction delay, telling 810338032Speter you how long it took to deliver to this address on the 810438032Speter last try. It is intended to be used for sorting mailing 810538032Speter lists to favor "quick" addresses. Provided for use by 810638032Speter the mailprio scripts (see below). 810738032Speter If a map cannot be opened, and that map is non-optional, and 810838032Speter an address requires that map for resolution, queue the 810938032Speter map instead of bouncing it. This involves creating a 811038032Speter pseudo-class of maps called "bogus-map" -- if a required 811138032Speter map cannot be opened, the class is changed to bogus-map; 811238032Speter all queries against bogus-map return "tempfail". The 811338032Speter bogus-map class is not directly accessible. A sample 811438032Speter implementation was donated by Jem Taylor of Glasgow 811538032Speter University Computing Service. 811638032Speter Fix a possible core dump when mailing to a program that talks 811738032Speter SMTP on its standard input. Fix from Keith Moore of 811838032Speter the University of Kentucky. 811938032Speter Make it possible to resolve filenames to $#local $: @ /filename; 812038032Speter previously, the "@" would cause it to not be recognized 812138032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 812238032Speter Accept a -1 signal to re-exec the daemon. This only works if 812338032Speter argv[0] is a full path to sendmail. 812438032Speter Fix bug in "addr=..." field in O option on little-endian machines 812538032Speter -- the network number wasn't being converted to network 812638032Speter byte order. Patch from Kurt Lidl of Pix Technologies 812738032Speter Corporation. 812838032Speter Pre-initialize the resolver early on; this is to avoid a bug with 812938032Speter BIND 4.9.3 that can cause the _res.retry field to get 813038032Speter reset to zero, causing all name server lookups to time 813138032Speter out. Fix from Matt Day of Artisoft. 813238032Speter Restore T line (trusted users) in config file -- but instead of 813338032Speter locking out the -f flag, they just tell whether or not 813438032Speter an X-Authentication-Warning: will be added. This really 813538032Speter just creates new entries in class 't', so "Ft/file/name" 813638032Speter can be used to read trusted user names from a file. 813738032Speter Trusted users are also allowed to execute programs even 813838032Speter if they have a shell that isn't in /etc/shells. 813938032Speter Improve NEWDB alias file rebuilding so it will create them 814038032Speter properly if they do not already exist. This had been 814138032Speter a MAYBENEXTRELEASE feature in 8.6.9. 814238032Speter Check for @:@ entry in NIS maps before starting up to avoid 814338032Speter (but not prevent, sigh) race conditions. This ought to 814438032Speter be handled properly in ypserv, but isn't. Suggested by 814538032Speter Michael Beirne of Motorola. 814638032Speter Refuse connections if there isn't enough space on the filesystem 814738032Speter holding the queue. Contributed by Robert Dana of Wolf 814838032Speter Communications. 814938032Speter Skip checking for directory permissions in the path to a file 815038032Speter when checking for file permissions iff setreuid() 815138032Speter succeeded -- it is unnecessary in that case. This avoids 815238032Speter significant performance problems when looking for .forward 815338032Speter files. Based on a suggestion by Win Bent of USC. 815438032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 815538032Speter arbitrary ruleset number assigned or "Sname = integer" 815638032Speter to assign a specific ruleset number. Reference is 815738032Speter $>name_or_number. Names can be composed of alphas, digits, 815838032Speter underscore, or hyphen (first character must be non-numeric). 815938032Speter Allow -o flag on AliasFile lines to make the alias file optional. 816038032Speter From Bryan Costales of ICSI. 816138032Speter Add NoRecipientAction option to handle the case where there is 816238032Speter no legal recipient header in the message. It can take 816338032Speter on values: 816438032Speter None Leave the message as is. The 816538032Speter message will be passed on even 816638032Speter though it is in technically 816738032Speter illegal syntax. 816838032Speter Add-To Add a To: header with any 816938032Speter recipients that it can find from 817038032Speter the envelope. This risks exposing 817138032Speter Bcc: recipients. 817238032Speter Add-Apparently-To Add an Apparently-To: header. This 817338032Speter has almost no redeeming social value, 817438032Speter and is provided only for back 817538032Speter compatibility. 817638032Speter Add-To-Undisclosed Add a header reading 817738032Speter To: undisclosed-recipients:; 817838032Speter which will have the effect of 817938032Speter making the message legal without 818038032Speter exposing Bcc: recipients. 818138032Speter Add-Bcc To add an empty Bcc: header. 818238032Speter There is a chance that mailers down 818338032Speter the line will delete this header, 818438032Speter which could cause exposure of Bcc: 818538032Speter recipients. 818638032Speter The default is NoRecipientAction=None. 818738032Speter Truncate (rather than delete) Bcc: lines in the header. This 818838032Speter should prevent later sendmails (at least, those that don't 818938032Speter themselves delete Bcc:) from considering this message to 819038032Speter be non-conforming -- although it does imply that non-blind 819138032Speter recipients can see that a Bcc: was sent, albeit not to whom. 819238032Speter Add SafeFileEnvironment option. If declared, files named as delivery 819338032Speter targets must be regular files in addition to the regular 819438032Speter checks. Also, if the option is non-null then it is used as 819538032Speter the name of a directory that is used as a chroot(2) 819638032Speter environment for the delivery; the file names listed in an 819738032Speter alias or forward should include the name of this root. 819838032Speter For example, if you run with 819938032Speter O SafeFileEnvironment=/arch 820038032Speter then aliases should reference "/arch/rest/of/path". If a 820138032Speter value is given, sendmail also won't try to save to 820238032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 820338032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 820438032Speter Support -A flag for alias files; this will comma concatenate like 820538032Speter entries. For example, given the aliases: 820638032Speter list: member1 820738032Speter list: member2 820838032Speter and an alias file declared as: 820938032Speter OAhash:-A /etc/aliases 821038032Speter the final alias inserted will be "list: member1,member2"; 821138032Speter without -A you will get an error on the second and subsequent 821238032Speter alias for "list".

Suggested by Liudvikas Bukys. 821438032Speter Fix a problem that could cause very long addresses to core dump in 821538032Speter some special circumstances. Problem pointed out by Allan 821638032Speter Johannesen. 821738032Speter (Internal change.) Change interface to expand() (macro expansion) 821838032Speter to be simpler and more consistent. 821938032Speter Delete check for funny qf file names. This didn't really give 822038032Speter any extra security and caused some people some problems. 822138032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 822238032Speter at compile time.) Suggested by Kyle Jones of UUNET. 822338032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 822438032Speter merge with DSN code; this is simpler and more consistent. 822538032Speter This may affect some people who have written their own 822638032Speter checkcompat() routine. 822738032Speter (Internal change.) Eliminate `D' line in qf file. The df file 822838032Speter is now assumed to be the same name as the qf file (with 822938032Speter the `q' changed to a `d', of course). 823038032Speter Avoid forking for delivery if all recipient mailers are marked as 823138032Speter "expensive" -- this can be a major cost on some systems. 823238032Speter Essentially, this forces sendmail into "queue only" mode 823338032Speter if all it is going to do is queue anyway. 823438032Speter Avoid sending a null message in some rather unusual circumstances 823538032Speter (specifically, the RCPT command returns a temporary 823638032Speter failure but the connection is lost before the DATA 823738032Speter command). Fix from Scott Hammond of Secure Computing 823838032Speter Corporation. 823938032Speter Change makesendmail to use a somewhat more rational naming scheme: 824038032Speter Makefiles and obj directories are named $os.$rel.$arch, 824138032Speter where $os is the operating system (e.g., SunOS), $rel is 824238032Speter the release number (e.g., 5.3), and $arch is the machine 824338032Speter architecture (e.g., sun4). Any of these can be omitted, 824438032Speter and anything after the first dot in a release number can 824538032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 824638032Speter version used $os.$arch.$rel and was rather less general. 824738032Speter Change makesendmail to do a "make depend" in the target directory 824838032Speter when it is being created. This involves adding an empty 824938032Speter "depend:" entry in most Makefiles. 825038032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 825138032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 825238032Speter of the Finnish Meteorological Institute. 825338032Speter Fix problem that could cause multiple responses to DATA command 825438032Speter on header syntax errors (e.g., lines beginning with colons). 825538032Speter Problem noted by Jens Thomassen of the University of Oslo. 825638032Speter Don't let null bytes in headers cause truncation of the rest of 825738032Speter the header. 825838032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 825938032Speter Increase timeouts on message data puts to allow time for receivers 826038032Speter to canonify addresses in headers on the fly. This is still 826138032Speter a rather ugly heuristic. From Motonori Nakamura. 826238032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 826338032Speter records are not used when canonifying names, and when MX 826438032Speter lookups are done for addressing they must be fully 826538032Speter qualified. This is useful if you have a wildcard MX record, 826638032Speter although it may cause other problems. In general, don't use 826738032Speter wildcard MX records. Patch from Motonori Nakamura. 826838032Speter Eliminate default two-line SMTP greeting message. Instead of 826938032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 827038032Speter is added between the first and second word of the first 827138032Speter line of the greeting message (i.e., immediately after the 827238032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 827338032Speter compile flag. Old sendmails won't see the ESMTP, but that's 827438032Speter acceptable because SIZE was the only useful extension that 827538032Speter old sendmails understand. 827638032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 827738032Speter invoked state dumps. From Masaharu Onishi. 827838032Speter Allow on-line comments in .forward and :include: files; they are 827938032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 828038032Speter is a space or a tab. This is intended for native 828138032Speter representation of non-ASCII sets such as Japanese, where 828238032Speter existing encodings would be unreadable or would lose 828338032Speter data -- for example, 828438032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 828538032Speter (romanized/less information) 828638032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 828738032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 828838032Speter (with MIME encoding, not human readable) 828938032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 829038032Speter (native encoding with ISO-2022-JP) 829138032Speter The last form is human readable in the Japanese environment. 829238032Speter Based on a fix from (surprise!) Motonori Nakamura. 829338032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 829438032Speter messages to that host; these are most frequently associated 829538032Speter with addresses rather than the host, with the exception of 829638032Speter 421 (service shutting down). The effect was to cause queues 829738032Speter to sometimes take an excessive time to flush. Reported by 829838032Speter Robert Sargent of Southern Geographics Technologies and 829938032Speter Eric Prestemon of American University. 830038032Speter Add Nice=N mailer option to set the niceness at which a mailer will 830138032Speter run. This is actually a relative niceness (that is, an 830238032Speter increment on the background value). 830338032Speter Log queue runs that are skipped due to high loads. They are logged 830438032Speter at LOG_INFO priority iff the log level is > 8. Contributed 830538032Speter by Bruce Nagel of Data General. 830638032Speter Allow the error mailer to accept a DSN-style error status code 830738032Speter instead of an sysexits status code in the host part. 830838032Speter Anything with a dot will be interpreted as a DSN-style code. 830938032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 831038032Speter to encode characters that might be munged by an EBCDIC system 831138032Speter in addition to the set required by RFC 1521. The additional 831238032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 831338032Speter (Think of "IBM 360" as the mnemonic for this flag.) 831438032Speter Change check for mailing to files to look for a pathname of [FILE] 831538032Speter rather than looking for the mailer named *file*. The mapping 831638032Speter of leading slashes still goes to the *file* mailer. This 831738032Speter allows you to implement the *file* mailer as a separate 831838032Speter program, for example, to insert a Content-Length: header 831938032Speter or do special security policy. However, note that the usual 832038032Speter initial checking for the file permissions is still done, and 832138032Speter the program in question needs to be very careful about how 832238032Speter it does the file write to avoid security problems. 832338032Speter Be able to read ~root/.forward even if the path isn't accessible to 832438032Speter regular users. This is disrecommended because sendmail 832538032Speter sometimes does not run as root (e.g., when an unsafe option 832638032Speter is specified on the command line), but should otherwise be 832738032Speter safe because .forward files must be owned by the user for 832838032Speter whom mail is being forwarded, and cannot be a symbolic link. 832938032Speter Suggested by Forrest Aldrich of Wang Laboratories. 833038032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 833138032Speter file. This is used for canonifying hostnames when the 833238032Speter service type is "files". 833338032Speter Implement programs on F (read class from file) line. The syntax is 833438032Speter Fc|/path/to/program to read the output from the program 833538032Speter into class "c". 833638032Speter Probe the network interfaces to find alternate names for this 833738032Speter host. Requires the SIOCGIFCONF ioctl call. Code 833838032Speter contributed by SunSoft. 833938032Speter Add "E" configuration line to set or propagate environment 834038032Speter variables into children. "E<envar>" will propagate 834138032Speter the named variable from the environment when sendmail 834238032Speter was invoked into any children it calls; "E<envar>=<value>" 834338032Speter sets the named variable to the indicated value. Any 834438032Speter variables not explicitly named will not be in the child 834538032Speter environment. However, sendmail still forces an 834638032Speter "AGENT=sendmail" environment variable, in part to enforce 834738032Speter at least one environment variable, since many programs and 834838032Speter libraries die horribly if this is not guaranteed. 834938032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 835038032Speter alias databases -- new algorithm looks for the substring 835138032Speter "/yp/" in the file name. This is more portable and involves 835238032Speter less overhead. Suggested by Motonori Nakamura. 835338032Speter Dynamically allocate the queue work list so that you don't lose 835438032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 835538032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 835638032Speter should not need to be changed) and the MaxQueueRunSize option, 835738032Speter which is the absolute maximum number of jobs that will ever 835838032Speter be handled in a single queue run. Based on code contributed 835938032Speter by Brian Coan of the Institute for Global Communications. 836038032Speter Log message when a message is dropped because it exceeds the maximum 836138032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 836238032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 836338032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 836438032Speter of Mark G. Thomas Consulting. 836538032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 836638032Speter OS-dependent defines). The old semantic of -d0.1 to not 836738032Speter run the daemon in background has been moved to -d99.100, 836838032Speter and the old 52.5 flag (to avoid disconnect() from closing 836938032Speter all output files) has been moved to 52.100. This makes 837038032Speter things more consistent (flags below .100 don't change 837138032Speter semantics) and separates out the backgrounding so that 837238032Speter it doesn't happen automatically on other unrelated debugging 837338032Speter flags. 837438032Speter If -t is used but no addresses are found in the header, give an 837538032Speter error message rather than just doing nothing. Fix from 837638032Speter Motonori Nakamura. 837738032Speter On systems (like SunOS) where the effective gid is not necessarily 837838032Speter included in the group list returned by getgroups(), the 837938032Speter `restrictmailq' option could sometimes cause an authorized 838038032Speter user to not be able to use `mailq'. Fix from Charles Hannum 838138032Speter of MIT. 838238032Speter Allow symbolic service names for [IPC] mailers. Suggested by 838338032Speter Gerry Magennis of Logica International. 838438032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 838538032Speter when running DNS. For example, if the name FTP.Foo.ORG is 838638032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 838738032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 838838032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 838938032Speter This is technically illegal under RFC 822 and 1123, but the 839038032Speter IETF is moving toward legalizing it. Note that turning on 839138032Speter this option is not sufficient to guarantee that a downstream 839238032Speter neighbor won't rewrite the address for you. 839338032Speter Add "-m" flag to makesendmail script -- this tells you what object 839438032Speter directory and Makefile it will use, but doesn't actually do 839538032Speter the make. 839638032Speter Do some additional checking on the contents of the qf file to try 839738032Speter to detect attacks against the qf file. In particular, 839838032Speter abort on any line beginning "From ", and add an "end of 839938032Speter file" line -- any data after that line is prohibited. 840038032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 840138032Speter choices. This can be overridden in the Makefile by using 840238032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 840338032Speter (to the extent that we know it) or by defining 840438032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 840538032Speter sendmail 8 to have more consistent installation instructions. 840638032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 840738032Speter of Sun Microsystems. 840838032Speter Improved symbol table hash function from Eric Wassenaar. This one 840938032Speter is at least 50% faster. 841038032Speter Fix problem that didn't notice that timeout on file open was a 841138032Speter transient error. Fix from Larry Parmelee of Cornell 841238032Speter University. 841338032Speter Allow comments (lines beginning with a `#') in files read for 841438032Speter classes. Suggested by Motonori Nakamura. 841538032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 841638032Speter of dropping out entirely. This makes testing some of the 841738032Speter name server lookups easier to deal with when there are 841838032Speter hung servers. From Motonori Nakamura. 841938032Speter Add new ${opMode} macro that is set to the current operation mode 842038032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 842138032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 842238032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 842338032Speter Kind of like queue-only mode (Odq) except it tries to avoid 842438032Speter any external service requests; for dial-on-demand hosts that 842538032Speter want to minimize DNS lookups when mail is being queued. For 842638032Speter this to work you will also have to make sure that gethostbyname 842738032Speter of your local host name does not do a DNS lookup. 842838032Speter Improved handling of "out of space" conditions from John Myers of 842938032Speter Carnegie Mellon. 843038032Speter Improved security for mailing to files on systems that have fchmod(2) 843138032Speter support. 843238032Speter Improve "cannot send message for N days" message -- now says "could 843338032Speter not send for past N days".

Patches 844738032Speter from Alexander Dupuy of System Management ARTS. 844838032Speter Delete duplicates in MX lists -- believe it or not, there are sites 844938032Speter that list the same host twice in an MX list. This deletion 845038032Speter only works on adjacent preferences, so an MX list that 845138032Speter had A=5, B=10, A=15 would leave both As, but one that had 845238032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 845338032Speter just in case there is something weird I haven't thought of. 845438032Speter Suggested by Barry Shein of Software Tool & Die. 845538032Speter SECURITY: .forward files cannot be symbolic links.

The semantics of this are undefined 855738032Speter for regular maps, but it can be useful for the user database. 855838032Speter MAKEMAP: lock database file while rebuilding to avoid sendmail 855938032Speter lookups while the rebuild is going on. There is a race 856038032Speter condition between the open(... O_TRUNC ...) and the lock 856138032Speter on the file, but it should be quite small. 856238032Speter SMRSH: sendmail restricted shell added to the release. This can 856338032Speter be used as an alternative to /bin/sh for the "prog" mailer, 856438032Speter giving the local administrator more control over what 856538032Speter programs can be run from sendmail. 856638032Speter MAIL.LOCAL: add this local mailer to the tape. It is not really 856738032Speter part of the release proper, and isn't fully supported; in 856838032Speter particular, it does not run on System V based systems and 856938032Speter never will. 857038032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 857138032Speter to allow rmail to compile on systems that don't have 857238032Speter function prototypes and systems that don't have snprintf. 857338032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 857438032Speter lists by transaction delay times so that addresses that 857538032Speter respond quickly get sent first. This is to prevent very 857638032Speter sluggish servers from delaying other peoples' mail. 857738032Speter Contributed by Tony Sanders of BSDI. 857838032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 857938032Speter of BSDI. This has a lot of comments to help people out. 858038032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 858138032Speter put this on the m4 command line. On GNU m4 (which 858238032Speter supports the __file__ primitive) you can run m4 in an 858338032Speter arbitrary directory -- use either: 858438032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 858538032Speter or 858638032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 858738032Speter On other versions of m4 that don't support __file__, you 858838032Speter can use: 858938032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 859038032Speter (Note the trailing slash on the _CF_DIR_ definition.) 859138032Speter Old versions of m4 will default to _CF_DIR_=.. for back 859238032Speter compatibility. 859338032Speter CONFIG: fix mail from <> so it will properly convert to 859438032Speter MAILER-DAEMON on local addresses. 859538032Speter CONFIG: fix code that was supposed to catch colons in host 859638032Speter names. Problem noted by John Gardiner Myers of CMU. 859738032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 859838032Speter From Paul Riddle of the University of Maryland, Baltimore 859938032Speter County. 860038032Speter CONFIG: Catch and reject "." as a host address. 860138032Speter CONFIG: Generalize domaintable to look up all domains, not 860238032Speter just unqualified ones. 860338032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 860438032Speter was never used and didn't work anyway. 860538032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 860638032Speter and d on all mailers in the UUCP class. 860738032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 860838032Speter look for an alias for "user+detail", then for "user+*", and 860938032Speter finally for "user". This is intended for forwarding mail 861038032Speter for system aliases such as root and postmaster to a 861138032Speter centralized hub. 861238032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 861338032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 861438032Speter The F=8 flag is also set on the "relay" mailer, since 861538032Speter this is expected to be another sendmail. 861638032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 861738032Speter the name of the UUCP_RELAY -- in some cases, this is the 861838032Speter wrong value (e.g., when we have local UUCP connections), 861938032Speter and this can create unreplyable addresses. From Chip 862038032Speter Rosenthal of Unicom. 862138032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 862264562Sgshapiro Received: header inserted into all messages. Suggested by 862338032Speter Gary Mills of the University of Manitoba. 862438032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 862543730Speter to get the old behavior. I did this upon observing 862638032Speter that almost everyone needed this feature, and that the 862738032Speter concept I was trying to make happen didn't work with 862838032Speter some user agents anyway. FEATURE(notsticky) still works, 862938032Speter but it is a no-op. 863038032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 863138032Speter names are sent, rather than immediately diagnosing them 863238032Speter as User Unknown. 863338032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 863438032Speter and RELAY_MAILER_ARGS to set the arguments for the 863538032Speter indicated mailers. All default to "IPC $h". Patch from 863638032Speter Larry Parmelee of Cornell University. 863738032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 863838032Speter on the client side" and F=P to get an appropriate 863938032Speter return-path. From Kimmo Suominen. 864038032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 864138032Speter as the local mailer. For addresses of the form "user+detail" 864238032Speter the "detail" part is passed to procmail via the -a flag. 864338032Speter Contributed by Kimmo Suominen. 864438032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 864538032Speter use from mailertables. This lets you execute arbitrary 864638032Speter procmail scripts. Contributed by Kimmo Suominen. 864738032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 864838032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 864938032Speter Paul Southworth of CICNet Systems Support. 865038032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 865138032Speter This causes the null return path to be rewritten as 865238032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 865338032Speter From Michael Hohmuth of Technische Universitat Dresden. 865438032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 865538032Speter list us as the best possible MX record to be treated as 865638032Speter though they were local (essentially, assume that they 865738032Speter are included in $=w). This can cause additional DNS 865838032Speter traffic, but is easier to administer if this fits your 865938032Speter local model. It does not work reliably if there are 866038032Speter multiple hosts that share the best MX preference. 866138032Speter Code contributed by John Oleynick of Rutgers. 866238032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 866338032Speter SHell) instead of /bin/sh as the program used for delivery 866438032Speter to programs. If an argument is included, it is used as 866538032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 866638032Speter assumed. 866738032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 866838032Speter size of messages to the local and procmail mailers 866938032Speter respectively. Contributed by Brad Knowles of the Defense 867038032Speter Information Systems Agency. 867138032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 867238032Speter (just like text outside of angle brackets) in order to 867338032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 867438032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 867538032Speter any real systems any more) and tweak the DOMAIN macro 867638032Speter so that it is less likely that users will accidentally use 867738032Speter the Berkeley defaults. Also, create some generic files 867838032Speter that really can be used in the real world. 867938032Speter CONFIG: Add new configuration macros to set character sets for 868038032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 868138032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 868238032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 868338032Speter The old name will still be accepted for a while at least. 868438032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 868538032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 868638032Speter As with all relays, it can be ``mailer:hostname''. Suggested 868738032Speter by Scott Hutton. 868838032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 868938032Speter by Barb Dijker of Labyrinth Computer Services. 869038032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 869138032Speter performance for large alias files, and this confused many 869238032Speter people. 869338032Speter CONFIG: Add confCF_VERSION to append local information to the 869438032Speter configuration version number displayed during SMTP startup. 869538032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 869638032Speter would only work when locally addressed. Fix from 869738032Speter Edvard Tuinder of Cistron Internet Services. 869838032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 869943730Speter "n" (CheckAliases) is set when rebuilding alias database. 870038032Speter Based on code contributed by Claude Marinier. 870138032Speter CONFIG: Allow mailertable to have values of the form 870238032Speter ``error:code message''. The ``code'' is a status code 870338032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 870438032Speter Contributed by David James <dwj@agw.bt.co.uk>. 870538032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 870638032Speter sender domains that will be replaced with the masquerade name. 870738032Speter These domains will not be treated as local, but if mail passes 870838032Speter through with sender addresses in those domains they will be 870938032Speter replaced by the masquerade name. These can also be specified 871038032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 871138032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 871238032Speter as well as the header. Substantial improvements to this 871338032Speter code were contributed by Per Hedeland. 871438032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 871538032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 871638032Speter by Kimmo Suominen. 871738032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 871838032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 871938032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 872038032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 872138032Speter UUCP addressing.

883264562Sgshapiro8.6.12/8.6.12 1995/03/28 883338032Speter Fix to IDENT code (it was getting the size of the reply buffer 883438032Speter too small, so nothing was ever accepted). Fix from several 883538032Speter people, including Allan Johannesen, Shane Castle of the 883638032Speter Boulder County Information Services, and Jeff Smith of 883738032Speter Warwick University (all arrived within a few hours of 883838032Speter each other!). 883938032Speter Fix a problem that could cause large jobs to run out of 884038032Speter file descriptors on systems that use vfork() rather 884138032Speter than fork(). 884238032Speter 884364562Sgshapiro8.6.11/8.6.11 1995/03/08 884438032Speter The ``possible attack'' message would be logged more often 884538032Speter than necessary if you are using Pine as a user agent. 884638032Speter The wrong host would be reported in the ``possible attack'' 884738032Speter message when attempted from IDENT. 884838032Speter In some cases the syslog buffer could be overflowed when 884938032Speter reporting the ``possible attack'' message. This can 885038032Speter cause denial of service attacks. Truncate the message 885138032Speter to 80 characters to prevent this problem. 885238032Speter When reading the IDENT response a loop is needed around the 885338032Speter read from the network to ensure that you don't get 885438032Speter partial lines. 885538032Speter Password entries without any shell listed (that is, a null 885638032Speter shell) wouldn't match as "ok". Problem noted by 885738032Speter Rob McMahon. 885838032Speter When running BIND 4.9.x a problem could occur because the 885938032Speter _res.options field is initialized differently than it 886038032Speter was historically -- this requires that sendmail call 886138032Speter res_init before it tweaks any bits. 886238032Speter Fix an incompatibility in openxscript() between the file open mode 886338032Speter and the stdio mode passed to fdopen. This caused UnixWare 886438032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 886538032Speter Novell Labs Europe. 886638032Speter Fix problem with static linking of local getopt routine when 886738032Speter using GNU's ld command. Fix from John Kennedy of 886838032Speter Cal State Chico. 886938032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 887238032Speter and Liudvikas Bukys. 887338032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 887438032Speter from Spider Boardman. 887538032Speter CONFIG: No changes (version number only, to keep it in sync 887638032Speter with the binaries). 887738032Speter 887864562Sgshapiro8.6.10/8.6.10 1995/02/10 887938032Speter SECURITY: Diagnose bogus values to some command line flags that 888038032Speter could allow trash to get into headers and qf files. 888138032Speter Validate the name of the user returned by the IDENT protocol. 888238032Speter Some systems that really dislike IDENT send intentionally 888338032Speter bogus information. Problem pointed out by Michael Bushnell 888438032Speter of the Free Software Foundation. Has some security 888538032Speter implications. 888638032Speter Fix a problem causing error messages about DNS problems when 888738032Speter the host name contained a percent sign to act oddly 888838032Speter because it was passed as a printf-style format string. 888938032Speter In some cases this could cause core dumps. 889038032Speter Avoid possible buffer overrun in returntosender() if error 889138032Speter message is quite long. From Fletcher Mattox of the 889238032Speter University of Texas. 889338032Speter Fix a problem that would silently drop "too many hops" error 889438032Speter messages if and only if you were sending to an alias. 889538032Speter From Jon Giltner of the University of Colorado and 889638032Speter Dan Harton of Oak Ridge National Laboratory. 889738032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 889838032Speter set and e->e_message was null. Fix from Bruce Nagel of 889938032Speter Data General. 890038032Speter Fix problem that can still cause df files to be left around 890138032Speter after "hop count exceeded" messages. Fix from Andrew 890238032Speter Chang and Shau-Ping Lo of SunSoft. 890338032Speter Fix a problem that can cause buffer overflows on very long 890438032Speter user names (as might occur if you piped to a program 890538032Speter with a lot of arguments). 890638032Speter Avoid returning an error and re-queueing if the host signature 890738032Speter is null; this can occur on addresses like ``user@.''. 890838032Speter Problem noted by Wesley Craig and the University of 890938032Speter Michigan. 891038032Speter Avoid possible calls to malloc(0) if MCI caching is turned 891138032Speter off. Bug fix from Pierre David of the Laboratoire 891238032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 891338032Speter Universite de Versailles - St Quentin, and Jacky 891438032Speter Thibault. 891538032Speter Make a local copy of the line being sent via senttolist() -- in 891638032Speter some cases, buffers could get trashed by map lookups 891738032Speter causing it to do unexpected things. This also simplifies 891838032Speter some of the map code. 891938032Speter CONFIG: No changes (version number only, to keep it in sync 892038032Speter with the binaries). 892138032Speter 892264562Sgshapiro8.6.9/8.6.9 1994/04/19 892338032Speter Do all mail delivery completely disconnected from any terminal. 892438032Speter This provides consistency with daemon delivery and 892538032Speter may have some security implications. 892638032Speter Make sure that malloc doesn't get called with zero size, 892738032Speter since that fails on some systems. Reported by Ed 892838032Speter Hill of the University of Iowa. 892938032Speter Fix multi-line values for $e (SMTP greeting message). Reported 893038032Speter by Mike O'Connor of Ford Motor Company. 893138032Speter Avoid syserr if no NIS domain name is defined, but the map it 893238032Speter is trying to open is optional. From Win Bent of USC. 893338032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 893438032Speter Hesiod support for UDB from Todd Miller of the University of 893538032Speter Colorado. Use "hesiod" as the service name in the U 893638032Speter option. 893738032Speter Fix a problem that failed to set the "authentic" host name (that 893838032Speter is, the one derived from the socket info) if you called 893938032Speter sendmail -bs from inetd. Based on code contributed by 894038032Speter Todd Miller (this problem was also reported by Guy Helmer 894138032Speter of Dakota State University). This also fixes a related 894238032Speter problem reported by Liudvikas Bukys of the University of 894338032Speter Rochester. 894438032Speter Parameterize "nroff -h" in all the Makefiles so people with 894538032Speter variant versions can use them easily. Suggested by 894638032Speter Peter Collinson of Hillside Systems. 894738032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 894838032Speter spaces between parameters instead of one. Reported by 894938032Speter Valdis Kletnieks of Virginia Tech. 895038032Speter Reduce the number of system calls during message collection by 895138032Speter using global timeouts around the collect() loop. This 895238032Speter code was contributed by Eric Wassenaar. 895338032Speter If the initial hostname name gathering results in a name 895438032Speter without a dot (usually caused by NIS misconfiguration) 895538032Speter and BIND is compiled in, directly access DNS to get 895638032Speter the canonical name. This should make life easier for 895738032Speter Solaris systems. If it still can't be resolved, and 895838032Speter if the name server is listed as "required", try again 895938032Speter in 30 seconds. If that also fails, exit immediately to 896038032Speter avoid bogus "config error: mail loops back to myself" 896138032Speter messages. 896238032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 896338032Speter message to explain how much space was available and 896438032Speter sound a bit less threatening. Suggested by Stan Janet 896538032Speter of the National Institute of Standards and Technology. 896638032Speter If mail is delivered to an alias that has an owner, deliver any 896738032Speter requested return-receipt immediately, and strip the 896838032Speter Return-Receipt-To: header from the subsequent message. 896938032Speter This prevents a certain class of denial of service 897038032Speter attack, arguably gives more reasonable semantics, and 897138032Speter moves things more towards what will probably become a 897238032Speter network standard. Suggested by Christopher Davis of 897338032Speter Kapor Enterprises. 897438032Speter Add a "noreceipts" privacy flag to turn off all return receipts 897538032Speter without recompiling. 897638032Speter Avoid printing ESMTP parameters as part of the error message 897738032Speter if there are errors during parsing. This change is 897838032Speter purely cosmetic. 897938032Speter Avoid sending out error messages during the collect phase of 898038032Speter SMTP; there is an MVS mailer from UCLA that gets 898138032Speter confused by this. Of course, I think it's their bug.... 898238032Speter Check for the $j macro getting undefined, losing a dot, or getting 898338032Speter lost from $=w in the daemon before accepting a connection; 898438032Speter if it is, it dumps state, prints a LOG_ALERT message, 898538032Speter and drops core for debugging. This is an attempt to 898638032Speter track down a bug that I thought was long since gone. 898738032Speter If you see this, please forward the log fragment to 898838032Speter sendmail@sendmail.ORG. 898938032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 899038032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 899138032Speter Wolfhugel. 899238032Speter Instead of trying to truncate the listen queue for the server 899338032Speter SMTP port when the load average is too high, just close 899438032Speter the port completely and reopen it later as needed. 899538032Speter This ensures that the other end gets a quick "connection 899638032Speter refused" response, and that the connection can be 899738032Speter recovered later. In particular, some socket emulations 899838032Speter seem to get confused if you tweak the listen queue 899938032Speter size around and can never start listening to connections 900038032Speter again. The down side is that someone could start up 900138032Speter another daemon process in the interim, so you could 900238032Speter have multiple daemons all not listening to connections; 900338032Speter this could in turn cause the sendmail.pid file to be 900438032Speter incorrect. A better approach might be to accept the 900538032Speter connection and give a 421 code, but that could break 900643730Speter other mailers in mysterious ways and have paging behavior 900738032Speter implications. 900838032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 900938032Speter set debugging on the wrong socket. From Eric Wassenaar. 901038032Speter When creating a df* temporary file, be sure you truncate any 901138032Speter existing data in the file -- otherwise system crashes 901238032Speter and the like could result in extra data being sent. 901338032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 901438032Speter doc directory. This includes some additional 901538032Speter information. 901638032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 901738032Speter of recipient envelope addresses. This should have been 901838032Speter handled by the $&h trick, but broke if people were 901938032Speter mixing domainized and UUCP addresses. They should 902038032Speter probably have converted all the way over to uucp-uudom 902138032Speter instead of uucp-{new,old}, but the failure mode was to 902238032Speter loop the mail, which was bad news. 902338032Speter Portability fixes: 902438032Speter Newer BSDI systems (several people). 902538032Speter Older BSDI systems from Christophe Wolfhugel. 902638032Speter Intergraph CLIX, from Paul Southworth of CICNet. 902738032Speter UnixWare, from Evan Champion. 902838032Speter NetBSD from Adam Glass. 902938032Speter Solaris from Quentin Campbell of the University of 903038032Speter Newcastle upon Tyne. 903138032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 903238032Speter Corporation. 903338032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 903438032Speter SunOS (it has setsid() and setvbuf() calls) from 903538032Speter Jonathan Kamens of OpenVision Technologies. 903638032Speter HP-UX from Tor Lillqvist. 903738032Speter New Files: 903838032Speter src/Makefile.CLIX 903938032Speter src/Makefile.NCR3000 904038032Speter doc/changes/Makefile 904138032Speter doc/changes/changes.me 904238032Speter doc/changes/changes.ps 904338032Speter 904464562Sgshapiro8.6.8/8.6.6 1994/03/21 904538032Speter SECURITY: it was possible to read any file as root using the 904638032Speter E (error message) option.

Thanks to Alain Durand of 905238032Speter INRIA for forwarding me the notice from the bugtraq 905338032Speter list. 905438032Speter 905564562Sgshapiro8.6.6/8.6.6 1994/03/13 905638032Speter SECURITY: the ability to give files away on System V-based 905738032Speter systems proved dangerous -- don't run as the owner 905838032Speter of a :include: file on a system that allows giveaways. 905938032Speter Unfortunately, this also applies to determining a 906038032Speter valid shell. 906138032Speter IMPORTANT: Previous versions weren't expiring old connections 906238032Speter in the connection cache for a long time under some 906338032Speter circumstances. This could result in resource exhaustion, 906438032Speter both at your end and at the other end. This checks the 906538032Speter connections for timeouts much more frequently. From 906638032Speter Doug Anderson of NCSC. 906738032Speter Fix a glitch that snuck in that caused programs to be run as 906838032Speter the sender instead of the recipient if the mail was 906938032Speter from a local user to another local user. From 907038032Speter Motonori Nakamura of Kyoto University. 907138032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 907238032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 907338032Speter Bryan Costales of ICSI. 907438032Speter Change the method used to declare the "statfs" availability; 907538032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 907638032Speter tweaking in conf.c, there is a single #define called 907738032Speter SFS_TYPE which takes on one of six values (SFS_NONE 907838032Speter for no statfs availability, SFS_USTAT for the ustat(2) 907938032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 908038032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 908138032Speter statfs(2) call with the declarations in <sys/vfs.h>, 908238032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 908338032Speter Fix glitch in NetInfo support that could return garbage if 908438032Speter there was no "/locations/sendmail" property. From 908538032Speter David Meyer of the University of Virginia. 908638032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 908738032Speter to allow Linux to turn it off even though it is a 908838032Speter BSD-like system. 908938032Speter Allow setting of "ident" timeout to zero to turn off the ident 909038032Speter protocol entirely. 909138032Speter Make 7-bit stripping local to a connection (instead of to a 909238032Speter mailer); this allows you to specify that SMTP is a 909338032Speter 7-bit channel, but revert to 8-bit should it advertise 909438032Speter that it supports 8BITMIME. You still have to specify 909538032Speter mailer flag 7 to get this stripping at all. 909638032Speter Improve makesendmail script so it handles more cases automatically. 909738032Speter Tighten up restrictions on taking ownership of :include: files 909838032Speter to avoid problems on systems that allow you to give away 909938032Speter files. 910038032Speter Fix a problem that made it impossible to rebuild the alias 910138032Speter file if it was on a read-only file system. From 910238032Speter Harry Edmon of the University of Washington. 910338032Speter Improve MX randomization function. From John Gardiner Myers 910438032Speter of CMU. 910538032Speter Fix a minor glitch causing a bogus message to be printed (used 910638032Speter %s instead of %d in a printf string for the line number) 910738032Speter when a bad queue file was read. From Harry Edmon. 910838032Speter Allow $s to remain NULL on locally generated mail. I'm not 910938032Speter sure this is necessary, but a lot of people have complained 911038032Speter about it, and there is a legitimate question as to whether 911138032Speter "localhost" is legal as an 822-style domain. 911238032Speter Fix a problem with very short line lengths (mailer L= flag) in 911338032Speter headers. This causes a leading space to be added onto 911438032Speter continuation lines (including in the body!), and also 911538032Speter tries to wrap headers containing addresses (From:, To:, 911638032Speter etc) intelligently at the shorter line lengths. Problem 911738032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 911838032Speter Log the real user name when logging syserrs, since these can have 911938032Speter security implications. Suggested by several people. 912038032Speter Fix address logging of cached connections -- it used to always 912138032Speter log the numeric address as zero. This is a somewhat 912238032Speter bogus implementation in that it does an extra system 912338032Speter call, but it should be an inexpensive one. Fix from 912438032Speter Motonori Nakamura. 912538032Speter Tighten up handling of short syslog buffers even more -- there 912638032Speter were cases where the outgoing relay= name was too long 912738032Speter to share a line with delay= and mailer= logging. 912838032Speter Limit the overhead on split envelopes to one open file descriptor 912938032Speter per envelope -- previously the overhead was three 913038032Speter descriptors. This was in response to a problem reported 913138032Speter by P{r (Pell) Emanuelsson. 913238032Speter Fixes to better handle the case of unexpected connection closes; 913338032Speter this redirects the output to the transcript so the info 913438032Speter is not lost. From Eric Wassenaar. 913538032Speter Fix potential string overrun if you macro evaluate a string that 913638032Speter has a naked $ at the end. Problem noted by James Matheson 913738032Speter <jmrm@eng.cam.ac.uk>. 913838032Speter Make default error number on $#error messages 553 (``Requested 913938032Speter action not taken: mailbox name not allowed'') instead of 914038032Speter 501 (``Syntax error in parameters or arguments'') to 914138032Speter avoid bogus "protocol error" messages. 914238032Speter Strip off any existing trailing dot on names during $[ ... $] 914338032Speter lookup. This prevents it from ending up with two dots 914438032Speter on the end of dot terminated names. From Wesley Craig 914538032Speter of the University of Michigan and Bryan Costales of ICSI. 914638032Speter Clean up file class reading so that the debugging information is 914738032Speter more informative. It hadn't been using setclass, so you 914838032Speter didn't see the class items being added. 914938032Speter Avoid core dump if you are running a version of sendmail where 915038032Speter NIS is compiled in, and you specify an NIS map, but 915138032Speter NIS is not running. Fix from John Oleynick of 915238032Speter Rutgers. 915338032Speter Diagnose bizarre case where res_search returns a failure value, 915438032Speter but sets h_errno to a success value. 915538032Speter Make sure that "too many hops" messages are considered important 915638032Speter enough to send an error to the Postmaster (that is, the 915738032Speter address specified in the P option). This fix should 915838032Speter help problems that cause the df file to be left around 915938032Speter sometimes -- unfortunately, I can't seem to reproduce 916038032Speter the problem myself. 916138032Speter Avoid core dump (null pointer reference) on EXPN command; this 916238032Speter only occurred if your log level was set to 10 or higher 916338032Speter and the target account was an alias or had a .forward file. 916438032Speter Problem noted by Janne Himanka. 916538032Speter Avoid "denial of service" attacks by someone who is flooding your 916638032Speter SMTP port with bad commands by shutting the connection 916738032Speter after 25 bad commands are issued. From Kyle Jones of 916838032Speter UUNET. 916938032Speter Fix core dump on error messages with very long "to" buffers; 917038032Speter fmtmsg overflows the message buffer. Fixed by trimming 917138032Speter the to address to 203 characters. Problem reported by 917238032Speter John Oleynick. 917338032Speter Fix configuration for HASFLOCK -- there were some spots where 917438032Speter a #ifndef was incorrectly #ifdef. Pointed out by 917538032Speter George Baltz of the University of Maryland. 917638032Speter Fix a typo in savemail() that could cause the error message To: 917738032Speter lists to be incorrect in some places. From Motonori 917838032Speter Nakamura. 917938032Speter Fix a glitch that can cause duplicate error messages on split 918038032Speter envelopes where an address on one of the lists has a 918138032Speter name server failure. Fix from Voradesh Yenbut of the 918238032Speter University of Washington. 918338032Speter Fix possible bogus pointer reference on ESMTP parameters that 918438032Speter don't have an ``=value'' part. 918538032Speter CNAME loops caused an error message to be generated, but also 918638032Speter re-queued the message. Changed to just re-queue the 918738032Speter message (it's really hard to just bounce it because 918838032Speter of the weird way the name server works in the presence 918938032Speter of CNAME loops). Problem noted by James M.R.Matheson 919038032Speter of Cambridge University. 919138032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 919238032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 919338032Speter user name. Suggested by Andreas Stolcke of ICSI. 919438032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 919538032Speter override it easily in the Makefile -- that is, you can 919638032Speter turn it off using -DNAMED_BIND=0. 919738032Speter If a gethostbyname(...) of an address with a trailing dot fails, 919838032Speter try it without the trailing dot. This is because if 919938032Speter you have a version of gethostbyname() that falls back 920038032Speter to NIS or the /etc/hosts file it will fail to find 920138032Speter perfectly reasonable names that just don't happen to 920238032Speter be dot terminated in the hosts file. You don't want to 920338032Speter strip the dot first though because we're trying to ensure 920438032Speter that country names that match one of your subdomains get 920538032Speter a chance. 920638032Speter PRALIASES: fix bogus output on non-null-terminated strings. 920738032Speter From Bill Gianopoulos of Raytheon. 920838032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 920938032Speter This was in code intended to only catch the self-literal 921038032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 921138032Speter IP address), but the code was broken. However, it will 921238032Speter still do this if $M is defined; this is necessary to 921338032Speter get client configurations to work (sigh). Note that this 921438032Speter means that $M overrides :mailname entries in the user 921538032Speter database! Problem noted by Paul Southworth. 921638032Speter CONFIG: Fix definition of Solaris help file location. From 921738032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 921838032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 921938032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 922038032Speter and USENET_MAILER_MAX to tweak the maximum message 922138032Speter size for various mailers. 922238032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 922338032Speter instead of assuming that it is "inews" for consistency 922438032Speter with other mailers. From Michael Corrigan of UC San Diego. 922538032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 922638032Speter qualify the address in the SMTP envelope as user@{relay|hub} 922738032Speter instead of user@$j. From Bill Wisner of The Well. 922838032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 922938032Speter CONFIG: Don't turn off case mapping of user names in the local 923038032Speter mailer for IRIX. This was different than most every other 923138032Speter system. 923238032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 923338032Speter envelope. Noted by Thierry Besancon 923438032Speter <besancon@excalibur.ens.fr>. 923538032Speter CONFIG: Don't include -z by default on uux line -- most systems 923638032Speter don't want it set by default. Pointed out by Philippe 923738032Speter Michel of Thomson CSF. 923838032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 923938032Speter host name was foo.bar.ray.com and you matched against 924038032Speter ".ray.com", the old implementation bound %1 to "bar" 924138032Speter instead of "foo.bar". Also, allow "." in the mailertable 924238032Speter to match anything -- essentially, take over SMART_HOST. 924338032Speter This also moves matching of explicit local host names 924438032Speter before the mailertable so they don't have to be special 924538032Speter cased in the mailertable data. Reported by Bill 924638032Speter Gianopoulos of Raytheon; the fix for the %1 binding 924738032Speter problem was contributed by Nicholas Comanos of the 924838032Speter University of Sydney. 924938032Speter CONFIG: Don't include "root" in class $=L (users to deliver 925038032Speter locally, even if a hub or relay exists) by default. 925138032Speter This is because of the known bug where definition of 925238032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 925338032Speter both and deliver into the local mailbox. 925438032Speter CONFIG: Move up bitdomain and uudomain handling so that they 925538032Speter are done before .UUCP class matching; uudomain was 925638032Speter reported as ineffective before. This also frees up 925738032Speter diversion 8 for future use. Problem reported by Kimmo 925838032Speter Suominen. 925938032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 926038032Speter into host names. As pointed out by Jonathan Kamens, 926138032Speter these are often used because either the forward or reverse 926238032Speter mapping is broken; this translation makes it broken again. 926338032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 926438032Speter Suominen. 926538032Speter Portability fixes: 926638032Speter Unicos from David L.

From 929038032Speter Bob Campbell at U.C. Berkeley. 929138032Speter Security fix: group ids were not completely set when programs 929238032Speter were invoked. This caused programs to have group 929338032Speter permissions they should not have had (usually group 929438032Speter daemon instead of their own group). In particular, 929538032Speter Perl scripts would refuse to run. 929638032Speter Security: check to make sure files that are written are not 929738032Speter symbolic links (at least under some circumstances). 929838032Speter Although this does not respond to a specific known 929938032Speter attack, it's just a good idea. Suggested by 930038032Speter Christian Wettergren. 930138032Speter Security fix: if a user had an NFS mounted home directory on 930238032Speter a system with a restricted shell listed in their 930338032Speter /etc/passwd entry, they could still execute any 930438032Speter program by putting that in their .forward file. 930538032Speter This fix prevents that by insisting that their shell 930638032Speter appear in /etc/shells before allowing a .forward to 930738032Speter execute a program or write a file. You can disable 930838032Speter this by putting "*" in /etc/shells. It also won't 930938032Speter permit world-writable :include: files to reference 931038032Speter programs or files (there's no way to disable this). 931143730Speter These behaviors are only one level deep -- for 931238032Speter example, it is legal for a world-writable :include: 931338032Speter file to reference an alias that writes a file, on 931438032Speter the assumption that the alias file is well controlled. 931538032Speter Security fix: root was not treated suspiciously enough when 931638032Speter looking into subdirectories. This would potentially 931738032Speter allow a cracker to examine files that were publicly 931838032Speter readable but in a non-publicly searchable directory. 931938032Speter Fix a problem that causes an error on QUIT on a cached 932038032Speter connection to create problems on the current job. 932138032Speter These are typically unrelated, so errors occur in 932238032Speter the wrong place. 932338032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 932438032Speter runs more responsive to load average, and fixes a 932538032Speter problem that ignored the load average in locally 932638032Speter generated mail. From Eric Wassenaar. 932738032Speter Fix possible core dump on aliases with null LHS. From 932838032Speter John Orthoefer of BB&N. 932938032Speter Revert to using flock() whenever possible -- there are just 933038032Speter too many bugs in fcntl() locking, particularly over 933138032Speter NFS, that cause sendmail to fail in perverse ways. 933238032Speter Fix a bug that causes the connection cache to get confused 933338032Speter when sending error messages. This resulted in 933438032Speter "unexpected close" messages. It should fix itself 933538032Speter on the following queue run. Problem noted by 933638032Speter Liudvikas Bukys of the University of Rochester. 933738032Speter Include $k in $=k as documented in the Install & Op Guide. 933838032Speter This seems odd, but it was documented.... From 933938032Speter Michael Corrigan of UCSD. 934038032Speter Fix problem that caused :include:s from alias files to be 934138032Speter forced to be owned by root instead of daemon 934238032Speter (actually DefUid). From Tim Irvin. 934338032Speter Diagnose unrecognized I option values -- from Mortin Forssen 934438032Speter of the Chalmers University of Technology. 934538032Speter Make "error" mailer work consistently when there is no error 934638032Speter code associated with it -- previously it returned OK 934738032Speter even though there was a real problem. Now it assumes 934838032Speter EX_UNAVAILABLE. 934938032Speter Fix bug that caused the last header line of messages that had 935038032Speter no body and which were terminated with EOF instead of 935138032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 935238032Speter Fix core dump on SMTP mail to programs that failed -- it tried 935338032Speter to go to a "next MX host" when none existed, causing 935438032Speter a core dump. From der Mouse at McGill University. 935538032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 935638032Speter this makes it easier to turn it off (using 935738032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 935838032Speter Fix YP_MASTER_NAME store to use the unupdated result of 935938032Speter gethostname() (instead of myhostname(), which tries 936038032Speter to fully qualify the name) to be consistent with 936138032Speter SunOS. If your hostname is unqualified, this fixes 936238032Speter transfers to slave servers. Bug noted by Keith 936338032Speter McMillan of Ameritech Services, Inc. 936438032Speter Fix Ultrix problem: gethostbyname() can return a very large 936538032Speter (> 500) h_length field, which causes the sockaddr 936638032Speter to be trashed. Use the size of the sockaddr instead. 936738032Speter Fix from Bob Manson of Ohio State. 936838032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 936938032Speter defined -- this confuses gethostbyname on hosts 937038032Speter file lookups, which doesn't understand the trailing 937138032Speter dot convention. 937238032Speter Log SMTP server subprocesses that die with a signal instead 937338032Speter of from a clean exit. 937438032Speter If you don't have option "I" set, don't assume that a DNS 937538032Speter "host unknown" message is authoritative -- it 937638032Speter might still be found in /etc/hosts. 937738032Speter Fix a problem that would cause Deferred: messages to be sent 937838032Speter as the subject of an error message, even though the 937938032Speter actual cause of a message was more severe than that. 938038032Speter Problem noted by Chris Seabrook of OSSI. 938138032Speter Fix race condition in DBM alias file locking. From Kyle 938238032Speter Jones of UUNET. 938338032Speter Limit delivery syslog line length to avoid bugs in some 938438032Speter versions of syslog(3). This adds a new compile time 938538032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 938638032Speter University, which is in turn derived from IDA. 938738032Speter Fix quotes inside of comments in addresses -- previously 938838032Speter it insisted that they be balanced, but the 822 spec 938938032Speter says that they should be ignored. 939038032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 939138032Speter debugging). This also evaluates ruleset 89, if set 939238032Speter (with the null input), and logs the result. This 939338032Speter should be used sparingly, since the rewrite process 939438032Speter is not reentrant. 939538032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 939638032Speter documented in the Bat Book. 939738032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 939838032Speter return an error message and did not requeue the message. 939938032Speter Fix based on code from Roland Dirlewanger of 940038032Speter Reseau Regional Aquarel, Bordeaux, France. 940138032Speter Fix a problem that caused a seg fault if you got a 421 error 940238032Speter code during some parts of connection initialization. 940338032Speter I've only seen this when talking to buggy mailers on 940438032Speter the other end, but it shouldn't give a seg fault in 940538032Speter any case. From Amir Plivatsky. 940638032Speter Fix core dump caused by a ruleset call that returns null. 940738032Speter Fix from Bryan Costales of ICSI. 940838032Speter Full-Name: field was being ignored.

Suggested by 941538032Speter Bryan Costales. 941638032Speter Initialize non-alias maps during alias rebuilds -- they may be 941738032Speter needed for parsing. Problem noted by Douglas Anderson. 941838032Speter Log sender address even if no message was collected in SMTP 941938032Speter (e.g., if all RCPTs failed). Suggested by Motonori 942038032Speter Nakamura. 942138032Speter Don't reflect the owner-list contents into the envelope sender 942238032Speter address if the value contains ", :, /, or | (to avoid 942338032Speter illegal addresses appearing there). 942438032Speter Efficiency hack for toktype macro -- from Craig Partridge of 942538032Speter BB&N. 942638032Speter Clean up DNS error printing so that a host name is always 942738032Speter included. 942838032Speter Remember to set $i during queue runs. Reported by Stephen 942938032Speter Campbell of Dartmouth University. 943038032Speter If the environment variable HOSTALIASES is set, use it during 943138032Speter canonification as the name of a file with per-user host 943238032Speter translations so that headers are properly mapped. Reported 943338032Speter by Anne Bennett of Concordia University. 943438032Speter Avoid printing misleading error message if SMTP mailer (not 943538032Speter using [IPC]) should die on a core dump. 943638032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 943738032Speter by the other end closing the connection. From 943838032Speter Dave Morrison of Oracle. 943938032Speter Improve several of the error messages printed by "mailq" 944038032Speter to include a host name or other useful information. 944138032Speter Add NetInfo preliminary support for NeXT systems. From Vince 944238032Speter DeMarco. 944338032Speter Fix a glitch that sometimes caused :include:s that pointed to 944438032Speter NFS filesystems that were down to give an "aliasing/ 944538032Speter forwarding loop broken" message instead of queueing 944638032Speter the message for retry. Noted by William C Fenner of 944738032Speter the NRL Connection Machine Facility. 944838032Speter Fix a problem that could cause a core dump if the input sequence 944938032Speter had (or somehow acquired) a \231 character. 945038032Speter Make sure that route-addrs always have <angle brackets> around 945138032Speter them in non-SMTP envelopes (SMTP envelopes already do 945238032Speter this properly). 945338032Speter Avoid weird headers on unbalanced punctuation of the form: 945438032Speter ``Joe User <user)'' -- this caused reference to the 945538032Speter null macro. Fix from Rick McCarty of IO.COM. 945638032Speter Fix a problem that caused an alias "user: user@local.host" to 945738032Speter not have the QNOTREMOTE bit set; this caused configs 945838032Speter to act as if FEATURE(notsticky) was defined even when 945938032Speter it was not. The effect of the problem was to make it 946038032Speter very hard to to set up satellite sites that had a few 946138032Speter local accounts, with everything else forwarded to a 946238032Speter corporate hub. Reported by Detlef Drewanz of the 946338032Speter University of Rostock and Mark Frost of NCD. 946438032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 946538032Speter addresses. This is more efficient (fewer name server 946638032Speter calls) and fixes certain unusual configurations, such 946738032Speter as those that have ruleset 4 do something that is 946838032Speter non-idempotent unless a mailer-specific ruleset did 946938032Speter something else. Problem reported by Brian J. Coan 947038032Speter of the Institute for Global Communications. 947138032Speter Fix the "obsolete argument" routine in main to better understand 947238032Speter new arguments. For example, if you used ``sendmail 947338032Speter -C config -v -q'' it would choke on the -q because 947438032Speter the -C would stop looking for old-format arguments. 947538032Speter Fix the code that was intended to allow two users to forward their 947638032Speter mail to the same program and have them appear unique. 947738032Speter Portability fixes for: 947838032Speter SCO UNIX from Murray Kucherawy. 947938032Speter SCO Open Server 3.2v4 from Philippe Brand. 948038032Speter System V Release 4 from Rick Ellis and others. 948138032Speter OSF/1 from Steve Campbell. 948238032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 948338032Speter of Stoner Associates. 948438032Speter Motorola SysV88 from Kevin Johnson of Motorola. 948538032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 949938032Speter of the config file has moved to /usr/lib 950038032Speter to match the HP-UX version of sendmail. 950138032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 950238032Speter since this is intended only for internal use, the 950338032Speter usual RFC 821/822/1123 rules can be relaxed. The 950438032Speter main point of this is to avoid munging (ugh) UUCP 950538032Speter addresses when relaying internally. 950638032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 950738032Speter syntax addresses delivered via UUCP. Solution 950838032Speter provided by Peter Wemm. 950938032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 951038032Speter zero; it caused double @ signs in addresses. From 951138032Speter Irving Reid of the University of Toronto. 951238032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 951338032Speter from Markku Toijala of ICL Personal Systems Oy. 951438032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 951538032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 951638032Speter that made it hard to recognize your own pseudodomain 951738032Speter names. 951838032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 951938032Speter rather than letting them get "local configuration 952038032Speter error"s. Problem noted by John Gardiner Myers. 952138032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 952238032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 952338032Speter has uucp-dom semantics but old UUCP syntax. This 952438032Speter also permits "uucp-old" as an alias for "uucp" and 952538032Speter "uucp-new" as a synonym for "suucp" for consistency. 952638032Speter CONFIG: add POP mailer support (from Kimmo Suominen 952738032Speter <kim@grendel.lut.fi>). 952838032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 952938032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 953038032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 953138032Speter was set; it would get an additional @masquerade.host 953238032Speter added to the address. Problem noted by Peter Wan 953338032Speter of Georgia Tech. 953438032Speter CONFIG: make sure that the local UUCP name is in $=w. From 953538032Speter Jim Murray of Stratus. 953638032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 953738032Speter mailer flag. Briefly, if you are sending to host 953838032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 953938032Speter "foo!baz" remains "foo!baz", and anything else has 954038032Speter the local name prepended. 954138032Speter CONFIG: portability fixes for HP-UX. 954238032Speter DOC: several minor problems fixed in the Install & Op Guide. 954338032Speter MAKEMAP: fix core dump problem on lines that are too long or 954438032Speter which lack newline. From Mark Delany. 954538032Speter MAILSTATS: print sums of columns (total messages & kbytes 954638032Speter in and out of the system). From Tom Ferrin of UC 954738032Speter San Francisco Computer Graphics Lab. 954838032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 954938032Speter On HP-UX, /etc/sendmail.cf has been moved to 955038032Speter /usr/lib/sendmail.cf to match HP sendmail. 955138032Speter Permissions have been tightened up on world-writable 955238032Speter :include: files and accounts that have shells 955338032Speter that are not listed in /etc/shells. This may 955438032Speter cause some .forward files that have worked 955538032Speter before to start failing. 955638032Speter SIGUSR1 dumps some state to the log. 955738032Speter NEW FILES: 955838032Speter src/Makefile.DGUX 955938032Speter src/Makefile.Dynix 956038032Speter src/Makefile.FreeBSD 956138032Speter src/Makefile.Mach386 956238032Speter src/Makefile.NetBSD 956338032Speter src/Makefile.RISCos 956438032Speter src/Makefile.SCO 956538032Speter src/Makefile.SVR4 956638032Speter src/Makefile.Titan 956738032Speter cf/mailer/pop.m4 956838032Speter cf/ostype/bsdi1.0.m4 956938032Speter cf/ostype/dgux.m4 957038032Speter cf/ostype/dynix3.2.m4 957138032Speter cf/ostype/sco3.2.m4 957238032Speter makemap/Makefile.dist 957338032Speter praliases/Makefile.dist 957438032Speter 957564562Sgshapiro8.6.4/8.6.4 1993/10/31 957638032Speter Repair core-dump problem (write to read-only memory segment) 957738032Speter if you fall back to the return-to-Postmaster case in 957838032Speter savemail. Problem reported by Richard Liu. 957938032Speter Immediately diagnose bogus sender addresses in SMTP. This 958038032Speter makes quite certain that crackers can't use this 958138032Speter class of attack. 958238032Speter Reliability Fix: check return value from fclose() and fsync() 958338032Speter in a few critical places. 958438032Speter Minor problem in initsys() that reversed a condition for 958538032Speter redirecting the output channel on queue runs. It's 958638032Speter not clear this code even does anything. From Eric 958738032Speter Wassenaar of the Dutch National Institute for Nuclear 958838032Speter and High-Energy Physics. 958938032Speter Fix some problems that caused queue runs to do "too much work", 959038032Speter such as double-reading the Errors-To: header. From 959138032Speter Eric Wassenaar. 959238032Speter Error messages on writing the temporary file (including the 959338032Speter data file) were getting suppressed in SMTP -- this 959438032Speter fix causes them to be properly reported. From Eric 959538032Speter Wassenaar. 959638032Speter Some changes to support AF_UNIX sockets -- this will only 959738032Speter really become relevant in the next release, but some 959838032Speter people need it for local patches. From Michael 959938032Speter Corrigan of UC San Diego. 960038032Speter Use dynamically allocated memory (instead of static buffers) 960138032Speter for macros defined in initsys() and settime(); since 960238032Speter these can have different values depending on which 960338032Speter envelope they are in. From Eric Wassenaar. 960438032Speter Improve logging to show ctladdr on to= logging; this tells you 960538032Speter what uid/gid processes ran as. 960638032Speter Fix a problem that caused error messages to be discarded if 960738032Speter the sender address was unparseable for some reason; 960838032Speter this was supposed to fall back to the "return to 960938032Speter postmaster" case. 961038032Speter Improve aliaswait backoff algorithm. 961138032Speter Portability patches for Linux (8.6.3 required another header 961238032Speter file) (from Karl London) and SCO UNIX. 961338032Speter CONFIG: patch prog mailer to not strip host name off of envelope 961438032Speter addresses (so that it matches local again). From 961538032Speter Christopher Davis. 961638032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 961738032Speter this prevents uux from seeing lines with null names like 961838032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 961938032Speter Nakamura of Kyoto University. 962038032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 962138032Speter it shouldn't fail miserably. From Motonori Nakamura. 962238032Speter 962364562Sgshapiro8.6.2/8.6.2 1993/10/15 962438032Speter Put a "successful delivery" message in the transcript for 962538032Speter addresses that get return-receipts. 962638032Speter Put a prominent "this is only a warning" message in warning 962738032Speter messages -- some people don't read carefully enough 962838032Speter and end up sending the message several times. 962938032Speter Include reason for temporary failure in the "warning" return 963038032Speter message. Currently, it just says "cannot send for 963138032Speter four hours". 963238032Speter Fix the "Original message received" time generated for 963338032Speter returntosender messages. It was previously listed as 963438032Speter the current time. Bug reported by Eric Hagberg of 963538032Speter Cornell University Medical College. 963638032Speter If there is an error when writing the body of a message, 963738032Speter don't send the trailing dot and wait for a response 963838032Speter in sender SMTP, as this could cause the connection to 963938032Speter hang up under some bizarre circumstances. From Eric 964038032Speter Wassenaar. 964138032Speter Fix some server SMTP synchronization problems caused when 964238032Speter connections fail during message collection. From 964338032Speter Eric Wassenaar. 964438032Speter Fix a problem that can cause srvrsmtp to reject mail if the 964538032Speter name server is down -- it accepts the RCPT but rejects 964638032Speter the DATA command. Problem reported by Jim Murray of 964738032Speter Stratus. 964838032Speter Fix a problem that can cause core dumps if the config file 964938032Speter incorrectly resolves to a null hostname. Reported by 965038032Speter Allan Johannesen of WPI. 965138032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 965238032Speter by non-root users were not put into 965338032Speter X-Authentication-Warning:s as intended because the 965443730Speter config file hadn't set the PrivacyOptions yet. Fix 965538032Speter from Sven-Ove Westberg of the University of Lulea. 965638032Speter Under very odd circumstances, the alias file rebuild code 965738032Speter could get confused as to whether a database was 965838032Speter open or not. 965938032Speter Check "vendor code" on the end of V lines -- this is 966038032Speter intended to provide a hook for vendor-specific 966138032Speter configuration syntax. (This is a "new feature", 966238032Speter but I've made an exception to my rule in a belief 966338032Speter that this is a highly exceptional case.) 966438032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 966538032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 966638032Speter (from Jon Forrest of UC Berkeley) 966738032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 966838032Speter 966964562Sgshapiro8.6.1/8.6 1993/10/08 967038032Speter Portability fixes for A/UX and Encore UMAX V. 967138032Speter Fix error message handling -- if you had a name server down 967238032Speter causing an error during parsing, that message was never 967338032Speter propagated to the queue file. 967438032Speter 967564562Sgshapiro8.6/8.6 1993/10/05 967638032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 967738032Speter conf.h (other systems have the same bug). 967838032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 967938032Speter getdtablesize() instead of sysconf(); a disturbingly 968038032Speter large number of systems defined _SC_OPEN_MAX in the 968138032Speter header files but don't have the syscall. 968238032Speter Another patch to really truly ignore MX records in getcanonname 968338032Speter if trymx == FALSE. 968438032Speter Fix problem that caused the "250 IAA25499 Message accepted for 968538032Speter delivery" message to be omitted if there was an error 968638032Speter in the header of the message (e.g., a bad Errors-To: 968738032Speter line). Pointed out by Michael Corrigan of UCSD. 968838032Speter Announce name of host we are chatting when we get errors; this 968938032Speter is an IDA-ism suggested by Christophe Wolfhugel. 969038032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 969138032Speter Australian Artificial Intelligence Institute), SCO Unix 969238032Speter (from Murray Kucherawy of Hookup Communication Corp.), 969338032Speter NeXT (from Vince DeMarco and myself), Linux (from 969438032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 969538032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 969638032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 969738032Speter Some changes to get around gcc optimizer bugs. From Takahiro 969838032Speter Kanbe. 969938032Speter Fix error recovery in queueup if another tf file of the same 970038032Speter name already exists. Problem stumbled over by Bill 970138032Speter Wisner of The Well. 970238032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 970338032Speter Problem noted by Keith McMillan of Ameritech Services. 970438032Speter Deal with group permissions properly when opening .forward and 970538032Speter :include: files. This relaxes the 8.1C restrictions 970638032Speter slightly more. This includes proper setting of groups 970738032Speter when reading :include: files, allowing you to read some 970838032Speter files that you should be able to read but have previously 970938032Speter been denied unless you owned them or they had "other" 971038032Speter read permission. 971138032Speter Make certain that $j is in $=w (after the .cf is read) so that 971238032Speter if the user is forced to override some silly system, 971338032Speter MX suppression will still work. 971438032Speter Fix a couple of efficiency problems where newstr was double- 971538032Speter calling expensive routines. In at least one case, it 971638032Speter wasn't guaranteed that they would always return the 971738032Speter same result. Problem noted by Christophe Wolfhugel. 971838032Speter Fix null pointer dereference in putoutmsg -- only on an error 971938032Speter condition from a non-SMTP mailer. From Motonori 972038032Speter Nakamura. 972138032Speter Macro expand "C" line class definitions before scanning so that 972238032Speter "CX $Z" works. 972338032Speter Fix problem that caused error message to be sent while still 972438032Speter trying to send the original message if the connection 972538032Speter is closed during a DATA command after getting an error 972638032Speter on an RCPT command (pretty obscure). Problem reported 972738032Speter by John Myers of CMU. 972838032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 972938032Speter term bug. 973038032Speter Fix a nasty bug causing core dumps when returning the "warning: 973138032Speter cannot deliver for N hours -- will keep trying" message; 973243730Speter it only occurred if you had PostmasterCopy set and 973338032Speter only on some architectures. Although sendmail would 973438032Speter keep trying, it would send error messages on each 973538032Speter queue interval. This is an important fix. 973638032Speter Allow u and g options to take user and group names respectively. 973738032Speter Don't do a chdir into the queue directory in -bt mode to make 973838032Speter ruleset testing a bit easier. 973938032Speter Don't allow users to turn off logging (using -oL) on the command 974038032Speter line -- command line can only raise, not lower, logging 974138032Speter level. 974238032Speter Set $u to the original recipient on the SMTP transaction or on 974338032Speter the command line. This is only done if there is exactly 974438032Speter one recipient. Technically, this does not meet the 974538032Speter specs, because it does not guarantee a domain on the 974638032Speter address. 974738032Speter Fix a problem that dumped error messages on bad addresses if 974838032Speter you used the -t flag. Problem noted by Josh Smith of 974938032Speter Harvey Mudd College. 975038032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 975138032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 975238032Speter avoid the problem of people who use angle brackets in 975338032Speter their full name information. 975438032Speter Fix a null pointer dereference if you set option "l", have 975538032Speter an Errors-To: header in the message, and have Errors-To: 975638032Speter defined in the config file H lines. From J.R. Oldroyd. 975738032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 975838032Speter wrong when compiling. Suggested by Rick McCarty of TI. 975938032Speter Fix a problem that could pass negative SIZE parameter if the 976038032Speter df file got lost; this would cause servers to always 976138032Speter give a temporary failure, making the problem even worse. 976238032Speter Problem noted by Allan Johannesen of WPI. 976338032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 976438032Speter protocol timeouts (30s default). Requested by Murray 976538032Speter Kucherawy of HookUp Communication Corp. to handle bogus 976638032Speter PC TCP/IP implementations. 976738032Speter Change $w default definition to be just the first component of 976838032Speter the domain name on config level 5. The $j macro defaults 976938032Speter to the FQDN; $m remains as before. This lets well-behaved 977038032Speter config files use any of the short, long, or subdomain 977138032Speter names. 977238032Speter Add makesendmail script in src to try to automate multi-architecture 977338032Speter builds. I know, this is sub-optimal, but it is still 977438032Speter helpful. 977538032Speter Fix very obscure race condition that can cause a queue run to 977638032Speter get a queue file for an already completed job. This 977738032Speter problem has existed for years. Problem noted by the 977838032Speter long suffering Allan Johannesen of WPI. 977938032Speter Fix a problem that caused the raw sender name to be passed to 978038032Speter udbsender instead of the canonified name -- this caused 978138032Speter it to sometimes miss records that it should have found. 978238032Speter Relax check of name on HELO packet so that a program using -bs 978338032Speter that claims to be itself works properly. 978438032Speter Restore rewriting of $: part of address through 2, R, 4 in 978538032Speter buildaddr -- this requires passing a lot of flags to get 978638032Speter it right. Unlike old versions, this ONLY rewrites 978738032Speter recipient addresses, not sender addresses. 978838032Speter Fix a bug that caused core dumps in config files that cannot 978938032Speter resolve /file/name style addresses. Fix from Jonathan 979038032Speter Kamens of OpenVision Technologies. 979138032Speter Fix problem with fcntl locking that can cause error returns to 979238032Speter be lost if the lock is lost; this required fully 979338032Speter queueing everything, dropping the envelope (so errors 979438032Speter would get returned), and then re-reading the queue from 979538032Speter scratch. 979638032Speter Fix a problem that caused aliases that redefine an otherwise 979738032Speter true address to still send to the original address 979838032Speter if and only if the alias failed in certain bizarre 979938032Speter ways (e.g, if they pointed at a list:; syntax address). 980038032Speter Problem pointed out by Jonathan Kamens. 980138032Speter Remove support for frozen configuration files. They caused 980238032Speter more trouble than it was worth. 980338032Speter Fix problem that can cause error messages to get ignored when 980438032Speter using both -odb and -t flags. Problem noted by Rob 980538032Speter McNicholas at U.C. Berkeley. 980638032Speter Include all "normal" variations on hostname in $=w. For example, 980738032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 980838032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 980938032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 981038032Speter the queue. 981138032Speter Reset SmtpPhase global on initial connection creation so that 981238032Speter messages don't come out with stale information. 981338032Speter Pass an "ext" argument to lockfile so that error/log messages 981438032Speter will properly reflect the true filename being locked. 981538032Speter Put all [...] address forms into $=w -- this eliminates the need 981638032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 981738032Speter Myers of CMU. 981838032Speter Fix a bug that can cause qf files to be left around even after 981938032Speter an SMTP RSET command. Problem and fix from Michael 982038032Speter Corrigan. 982143730Speter Don't send a PostmasterCopy to errors when the Precedence: is 982238032Speter negative. Error reports still go to the envelope 982338032Speter sender address. 982438032Speter Add LA_SHORT for load averages. 982538032Speter Lock sendmail.st file when posting statistics. 982638032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 982738032Speter set the size of the TCP send and receive buffers; if you 982838032Speter run over a slow slip line you may need to set these down 982938032Speter (although it would be better to fix the SLIP implementation 983038032Speter so that it's not necessary to recompile every program 983138032Speter that does bulk data transfer). 983238032Speter Allow null defaults on $( ... $) lookups. Problem reported by 983338032Speter Amir Plivatsky. 983438032Speter Diagnose crufty S and V config lines. This resulted from an 983538032Speter observation that some people were using the SITE macro 983638032Speter without the SITECONFIG macro first, which was causing 983738032Speter bogus config files that were not caught. 983838032Speter Fix makemap -f flag to turn off case folding (it was turning it 983938032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 984038032Speter Fix a problem that caused multiple error messages to be sent if 984138032Speter you used "sendmail -t -oem -odb", your system uses fcntl 984238032Speter locking, and one of the recipient addresses is unknown. 984338032Speter Reset uid earlier in include() so that recursive .forwards or 984438032Speter :include:s don't use the wrong uid. 984538032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 984638032Speter called, the code to recover the descriptor was broken. 984738032Speter This sometimes (only sometimes) caused problems with the 984838032Speter alias file. Fix from Motonori Nakamura. 984938032Speter Fix a problem that caused aliaswait to go into infinite recursion 985038032Speter if the @:@ metasymbol wasn't found in the alias file. 985138032Speter Improve error message on newaliases if database files cannot be 985238032Speter opened or if running with no database format defined. 985338032Speter Do a better estimation of the size of error messages when NoReturn 985438032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 985538032Speter Fix a problem causing the "c" option (don't connect to expensive 985638032Speter mailers) to be ignored in SMTP. Problem noted and the 985738032Speter solution suggested by Robert Elz of The University of 985838032Speter Melbourne. 985938032Speter Improve connection caching algorithm by passing "[host]" to 986038032Speter hostsignature, which strips the square brackets and 986138032Speter returns the real name. This allows mailertable entries 986238032Speter to match regular entries. 986338032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 986438032Speter feature, even if it doesn't work right. 986538032Speter Catch and log attempts to try the "wiz" command in server SMTP. 986638032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 986738032Speter Be more generous at assigning $z to the home directory -- do this 986838032Speter for programs that are specified through a .forward file. 986938032Speter Fix from Andrew Chang of Sun Microsystems. 987038032Speter Always save a fatal error message in preference to a non-fatal 987138032Speter error message so that the "subject" line of return 987238032Speter messages is the best possible. 987338032Speter CONFIG: reduce the number of quotes needed to quote configuration 987438032Speter parameters with commas: two quotes should work now, e.g., 987538032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 987638032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 987738032Speter connections (domain-ized UUCP). 987838032Speter CONFIG: fix bug in default maps (-o must be before database file 987964562Sgshapiro name). Pointed out by Christophe Wolfhugel. 988038032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 988138032Speter DNS. This would presumably be used in UUCP islands. 988238032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 988338032Speter CONFIG: log $u in Received: line. This is in technical violation 988438032Speter of the standards, since it doesn't guarantee a domain 988538032Speter on the address. 988638032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 988738032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 988838032Speter the "m" flag should you want it. Apparently some Solaris 2.2 988938032Speter installations can't handle multiple local recipients. 989038032Speter Problem noted by Josh Smith. 989138032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 989238032Speter CONFIG: change default version level from 4 to 5. 989338032Speter CONFIG: add FEATURE(nullclient) to create a config file that 989438032Speter forwards all mail to a hub without ever looking at the 989538032Speter addresses in any detail. 989638032Speter CONFIG: properly strip mailer: information off of relays when 989738032Speter used to change .BITNET form into %-hack form. 989838032Speter CONFIG: fix a problem that caused infinite loops if presented 989938032Speter with an address such as "!foo". 990038032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 990138032Speter the reverse "PTR" mapping is broken. There's a better 990238032Speter way to do this, but the change is fairly major and I 990338032Speter want to hold it for another release. Problem noted by 990438032Speter Bret Marquis. 990538032Speter 990664562Sgshapiro8.5/8.5 1993/07/23 990738032Speter Serious bug: if you used a command line recipient that was unknown 990838032Speter sendmail would not send a return message (it was treating 990938032Speter everything as though it had an SMTP-style client that 991038032Speter would do the return itself). Problem noted by Josh Smith. 991138032Speter Change "trymx" option in getcanonname() to ignore all MX data, 991238032Speter even during a T_ANY query. This actually didn't break 991338032Speter anything, because the only time you called getcanonname 991438032Speter with !trymx was if you already knew there were no MX 991538032Speter records, but it is somewhat cleaner. From Motonori 991638032Speter Nakamura. 991738032Speter Don't call getcanonname from getmxrr if you already know there 991838032Speter are no DNS records matching the name. 991938032Speter Fix a problem causing error messages to always include "The 992038032Speter original message was received ... from localhost". 992138032Speter The correct original host information is now included. 992238032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 992338032Speter version of "test" doesn't have the -x flag). Change it 992438032Speter to use -f instead. From John Myers. 992538032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 992638032Speter esmtp -- it should be smtp. 992738032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 992838032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 992938032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 993038032Speter this cleans up the configs somewhat. This fixes a serious 993138032Speter problem that caused route-addrs to get mistaken as relays, 993238032Speter pointed out by John Myers. WARNING: this also causes 993338032Speter the default on SMART_HOST to change from "suucp" to 993438032Speter "relay" if you have MAILER(smtp) specified. 993538032Speter 993664562Sgshapiro8.4/8.4 1993/07/22 993738032Speter Add option `w'. If you receive a message that comes to you because 993838032Speter you are the best (lowest preference) target of an MX, and 993938032Speter you haven't explicitly recognized the source MX host in 994038032Speter your .cf file, this option will cause you to try the target 994138032Speter host directly (as if there were no MX for it at all). If 994238032Speter `w' is not set, this case is a configuration error. 994338032Speter Beware: if `w' is set, senders may get bogus errors like 994438032Speter "message timed out" or "host unknown" for problems that 994538032Speter are really configuration errors. This option is 994638032Speter disrecommended, provided only for compatibility with 994738032Speter UIUC sendmail. 994838032Speter Fix a problem that caused the incoming socket to be left open 994938032Speter when sendmail forks after the DATA command. This caused 995038032Speter calling systems to wait in FIN_WAIT_2 state until the 995138032Speter entire list was processed and the child closed -- a 995238032Speter potentially prodigious amount of time. Problem noted 995338032Speter by Neil Rickert. 995438032Speter Fix problem (created in 6.64) that caused mail sent to multiple 995538032Speter addresses, one of which was a bad address, to completely 995638032Speter suppress the sending of the message. This changes 995738032Speter handling of EF_FATALERRS somewhat, and adds an 995838032Speter EF_GLOBALERRS flag. This also fixes a potential problem 995938032Speter with duplicate error messages if there is a syntax error 996038032Speter in the header of a message that isn't noticed until late 996138032Speter in processing. Original problem pointed out by Josh Smith 996238032Speter of Harvey Mudd College. This release includes quite a bit 996338032Speter of dickering with error handling (see below). 996438032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 996538032Speter will only hurt already-broken software and should help 996638032Speter humans. 996738032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 996838032Speter compiled in. It would never read the alias file. 996938032Speter Repair unbalanced `)' and `>' (the "open" versions are already 997038032Speter repaired). 997138032Speter Logging of "done" in dropenvelope() was incorrect: it would 997238032Speter log this even when the queue file still existed. Change 997338032Speter this to only log "done" (at log level 11) when the 997438032Speter queue file is actually removed. From John Myers. 997538032Speter Log "lost connection" in server SMTP at log level 20 if there 997638032Speter is no pending transaction. Some senders just close the 997738032Speter connection rather than sending QUIT. 997838032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 997938032Speter domains that do not have MX records -- this would cause 998038032Speter the subsequent host name lookup to fail. The problem 998138032Speter only occurred if you had FEATURE(nocanonify) set. 998238032Speter Problem noted by Rick McCarty of Texas Instruments. 998338032Speter Fix invocation of setvbuf when passed a -X flag -- I had 998438032Speter unwittingly used an ANSI C extension, and this caused 998538032Speter core dumps on some machines. 998638032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 998738032Speter Previously it just gave an empty send queue, which 998838032Speter then gave either "Need RCPT (recipient)" at the DATA 998938032Speter (confusing, since you had given an RCPT command which 999038032Speter returned 250) or just dropped the email, depending on 999138032Speter whether you were running VERBose mode. Now it usually 999238032Speter diagnoses this case as "aliasing/forwarding loop broken". 999338032Speter Unfortunately, it still doesn't adequately diagnose 999438032Speter some true error conditions. 999538032Speter Add internal concept of "warning messages" using 6xx codes. 999638032Speter These are not reported only to Postmaster. Unbalanced 999738032Speter parens, brackets, and quotes are printed as 653 codes. 999838032Speter They are always mapped to 5xx codes before use in SMTP. 999938032Speter Clean up error messages to tell both the actual address that 1000038032Speter failed and the alias they arose from. This makes it 1000138032Speter somewhat easier to diagnose problems. Difficulty noted 1000238032Speter by Motonori Nakamura. 1000338032Speter Fix a problem that inappropriately added a ctladdr to addresses 1000438032Speter that shouldn't have had one during a queue run. This 1000538032Speter caused error messages to be handled differently during 1000638032Speter a queue run than a direct run. 1000738032Speter Don't print the qf name and line number if you get errors during 1000838032Speter the direct run of the queue from srvrsmtp -- this was 1000938032Speter just extra stuff for users to crawl through. 1001038032Speter Put command line flags on second line of pid file so you can 1001138032Speter auto-restart the daemon with all appropriate arguments. 1001238032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 1001338032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 1001438032Speter restart it. 1001538032Speter Remove the ``setuid(getuid())'' in main -- this caused the 1001638032Speter IDENT daemon to screw up. This required that I change 1001738032Speter HASSETEUID to HASSETREUID and complicate the mode 1001838032Speter changing somewhat because both Ultrix and SunOS seem 1001938032Speter to have a bug causing seteuid() to set the saved uid 1002038032Speter as well as the effective. The program test/t_setreuid.c 1002138032Speter will test to see if your implementation of setreuid(2) 1002238032Speter is appropriately functional. 1002338032Speter The FallBackMX (option V) handling failed to properly identify 1002438032Speter fallback to yourself -- most of the code was there, 1002538032Speter but it wasn't being enabled. Problem noted by Murray 1002638032Speter Kucherawy of the University of Waterloo. 1002738032Speter Change :include: open timeout from ETIMEDOUT to an internal 1002838032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 1002938032Speter with CurHostName" in error messages, which can be 1003038032Speter confusing. Reported by Jonathan Kamens of OpenVision 1003138032Speter Technologies. 1003238032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 1003338032Speter process group id. The original fix was to get around 1003438032Speter some problems with recalcitrant MUAs, but it breaks 1003538032Speter any call from a shell that creates a process group id 1003638032Speter different from the process id. I could try to fix 1003738032Speter this by diddling the tty owner (using tcsetpgrp or 1003838032Speter equivalent) but this is too likely to break other 1003938032Speter things. 1004038032Speter Portability changes: 1004138032Speter Support -M as equivalent to -oM on Ultrix -- apparently 1004238032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 1004338032Speter instead of using standard flags. Oh joy. This 1004443730Speter behavior reported by Jon Giltner of University 1004538032Speter of Colorado. 1004638032Speter SGI IRIX -- this includes several changes that should 1004738032Speter help other strict ANSI compilers. 1004838032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 1004938032Speter Corporation. 1005038032Speter Solaris running the Sun C compiler (which despite the 1005138032Speter documentation apparently doesn't define 1005238032Speter __STDC__ by default). 1005338032Speter ConvexOS from Eric Schnoebelen of Convex. 1005438032Speter Sony NEWS workstations and Omron LUNA workstations from 1005538032Speter Motonori Nakamura. 1005638032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 1005738032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 1005838032Speter several people have made a good argument that this 1005938032Speter creates more problems than it solves (although this 1006038032Speter may prove painful in the short run). 1006138032Speter CONFIG: generalize all the relays to accept a "mailer:host" 1006238032Speter format. 1006338032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 1006438032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1006538032Speter addresses are also passed through this ruleset. 1006638032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1006738032Speter internet-style addresses would "fall off the end" of 1006838032Speter ruleset zero and be interpreted as local -- however, 1006938032Speter the angle brackets confused the recursive call. 1007038032Speter These are now diagnosed as "Unrecognized host name". 1007138032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1007238032Speter ifdef(`_MAILER_USENET_') instead of 1007338032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1007438032Speter of SINTEF RUNIT, Oslo. 1007538032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1007638032Speter early in ruleset 0; this allows .mc authors to bypass 1007738032Speter things like the "short circuit" code for local addresses. 1007838032Speter Prompted by a comment by Bill Wisner of The Well. 1007938032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1008038032Speter esmtp) to send SMTP mail. This allows you to default 1008138032Speter to esmtp but use a mailertable or other override to 1008238032Speter deal with broken servers. This logic was pointed out 1008338032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1008438032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1008538032Speter environments. Ugly as sin. 1008638032Speter 1008764562Sgshapiro8.3/8.3 1993/07/13 1008838032Speter Fix setuid problems introduced in 8.2 that caused messages 1008938032Speter like "Cannot create qfXXXXXX: Invalid argument" 1009038032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1009138032Speter involved a new compile flag "HASSETEUID" that takes 1009238032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1009338032Speter that the POSIX interface is broken enough to break 1009438032Speter some systems badly. This includes some fixes for 1009538032Speter HP-UX. Also fixes problems where the real uid is 1009638032Speter not reset properly on startup (from Neil Rickert). 1009738032Speter Fix a problem that caused timed out messages to not report the 1009838032Speter addresses that timed out. Error messages are also more 1009938032Speter "user friendly". 1010038032Speter Drop required bandwidth on connections from 64 bytes/sec to 1010138032Speter 16 bytes/sec. 1010238032Speter Further Solaris portability changes -- doesn't require the BSD 1010338032Speter compatibility library. This also adds a new 1010438032Speter "HASGETDTABLESIZE" compile flag which can be used if 1010538032Speter you want to use getdtablesize(2) instead of sysconf(2). 1010638032Speter These are loosely based on changes from David Meyer at 1010738032Speter University of Oregon. This now seems to work, at least 1010838032Speter for quick test cases. 1010938032Speter Fix a problem that can cause duplicate error messages to be 1011038032Speter sent if you are in SMTP, you send to multiple addresses, 1011138032Speter and at least one of those addresses is good and points 1011238032Speter to an account that has a .forward file (whew!). 1011338032Speter Fix a problem causing messages to be discarded if checkcompat() 1011438032Speter returned EX_TEMPFAIL (because it didn't properly mark 1011538032Speter the "to" address). Problem noted by John Myers. 1011638032Speter Fix dfopen to return NULL if the open failed; I was depending 1011738032Speter on fdopen(-1) returning NULL, which isn't the case. This 1011838032Speter isn't serious, but does result in weird error diagnoses. 1011938032Speter From Michael Corrigan. 1012038032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1012138032Speter messages sent through UUCP-family mailers. Suggested 1012238032Speter by Bill Wisner of The Well. 1012338032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1012438032Speter include a "uucp-dom" mailer that uses domain-style 1012538032Speter addressing. Suggested by Bill Wisner. 1012638032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1012738032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1012838032Speter Christophe Wolfhugel. 1012938032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1013038032Speter 1013164562Sgshapiro8.2/8.2 1993/07/11 1013238032Speter Don't drop out on config file parse errors in -bt mode. 1013338032Speter On older configuration files, assume option "l" (use Errors-To 1013438032Speter header) for back compatibility. NOTE: this DOES NOT 1013538032Speter imply an endorsement of the Errors-To: header in any way. 1013638032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1013738032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1013838032Speter SMTP server to give an error on this command, and 1013938032Speter logging it in the transcript can be confusing. Fix 1014038032Speter from Bill Wisner. 1014138032Speter IRIX compatibility changes provided by Dan Rich 1014238032Speter <drich@sandman.lerc.nasa.gov>. 1014338032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1014438032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1014538032Speter <juo@klinzhai.rutgers.edu> 1014638032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1014738032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1014838032Speter match the other flags in that file. 1014938032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1015038032Speter Save h_errno in mci struct and improve error message display. 1015138032Speter Changes from Eric Wassenaar. 1015238032Speter Open /dev/null for the transcript if the create of the xf file 1015338032Speter failed; this avoids at least one possible null pointer 1015438032Speter reference in very weird cases. From Eric Wassenaar. 1015538032Speter Clean up statistics gathering; it was over-reporting because of 1015638032Speter forks. From Eric Wassenaar. 1015738032Speter Fix problem that causes old Return-Path: line to override new 1015838032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1015938032Speter re-using old value). From Motonori Nakamura. 1016038032Speter Fix broken -m flag in K definition -- even if -m (match only) 1016138032Speter was specified, it would still replace the key with the 1016238032Speter value. Noted by Rick McCarty of Texas Instruments. 1016338032Speter If the name server timed out over several days, no "timed out" 1016438032Speter message would ever be sent back. The timeout code 1016538032Speter has been moved from markfailure() to dropenvelope() 1016638032Speter so that all such failures should be diagnosed. Pointed 1016738032Speter out by Christophe Wolfhugel and others. 1016838032Speter Relax safefile() constraints: directories in an include or 1016938032Speter forward path must be readable by self if the controlling 1017038032Speter user owns the entry, readable by all otherwise (e.g., 1017138032Speter when reading your .forward file, you have to own and 1017238032Speter have X permission in it; everyone needs X permission in 1017338032Speter the root and directories leading up to your home); 1017438032Speter include files must be readable by anyone, but need not 1017538032Speter be owned by you. 1017638032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1017738032Speter reading a .forward file; this gets around some problems 1017838032Speter on NFS mounts if root permission is not exported and 1017938032Speter the user's home directory isn't x'able. 1018038032Speter Additional NeXT portability enhancements from Axel Zinser. 1018138032Speter Additional HP-UX portability enhancements from Brian Bullen. 1018238032Speter Add a timeout around SMTP message writes; this assumes you can 1018338032Speter get throughput of at least 64 bytes/second. Note that 1018438032Speter this does not impact the "datafinal" default, which 1018538032Speter is separate; this is just intended to work around 1018638032Speter network clogs that will occur before the final dot 1018738032Speter is sent. From Eric Wassenaar. 1018838032Speter Change map code to set the "include null" flag adaptively -- 1018938032Speter it initially tries both, but if it finds anything 1019038032Speter matching without a null it never tries again with a 1019138032Speter null and vice versa. If -N is specified, it never 1019238032Speter tries without the null and creates new maps with a 1019338032Speter null byte. If -O is specified, it never tries with 1019438032Speter the null (for efficiency). If -N and -O are specified, 1019538032Speter you get -NO (get it?) lookup at all, so this would 1019638032Speter be a bad idea. If you don't specify either -N or -O, 1019738032Speter it adapts. 1019838032Speter Fix recognition of "same from address" so that MH submissions 1019938032Speter will insert the appropriate full name information; 1020038032Speter this used to work and got broken somewhere along the 1020138032Speter way. 1020238032Speter Some changes to eliminate some unnecessary SYSERRs in the 1020338032Speter log. For example, if you lost a connection, don't 1020438032Speter bother reporting that fact on the connection you lost. 1020538032Speter Add some "extended debugging" flags to try to track down 1020638032Speter why we get occasional problems with file descriptor 1020738032Speter one being closed when execing a mailer; it seems to 1020838032Speter only happen when there has been another error in the 1020938032Speter same transaction. This requires XDEBUG, defined 1021038032Speter by default in conf.h. 1021138032Speter Add "-X filename" command line flag, which logs both sides of 1021238032Speter all SMTP transactions. This is intended ONLY for 1021338032Speter debugging bad implementations of other mailers; start 1021438032Speter it up, send a message from a mailer that is failing, 1021538032Speter and then kill it off and examine the indicated log. 1021638032Speter This output is not intended to be particularly human 1021738032Speter readable. This also adds the HASSETVBUF compile 1021838032Speter flag, defaulted on if your compiler defines __STDC__. 1021938032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1022038032Speter have a local net that should get direct connects, you 1022138032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1022238032Speter See cf/README for an example. 1022338032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1022438032Speter sites that don't use the -d flag. 1022538032Speter CONFIG: hide recipient addresses as well as sender addresses 1022638032Speter behind $M if FEATURE(allmasquerade) is specified; this 1022738032Speter has been requested by several people, but can break 1022838032Speter local aliases. For example, if you mail to "localalias" 1022938032Speter this will be rewritten as "localalias@masqueradehost"; 1023038032Speter although initial delivery will work, replies will be 1023138032Speter broken. Use it sparingly. 1023238032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1023338032Speter to qualified domains in headers. I believe this is 1023438032Speter largely equivalent to the IDA feature of the same name. 1023538032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1023638032Speter to override the "system name" as your UUCP name -- 1023738032Speter in particular, to use domain-ized UUCP names. From 1023838032Speter Bill Wisner of The Well. 1023938032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1024038032Speter first. This is currently unused in the config files, 1024138032Speter but could be used in a mailertable entry. 1024238032Speter 1024364562Sgshapiro8.1C/8.1B 1993/06/27 1024438032Speter Serious security bug fix: it was possible to read any file on 1024538032Speter the system, regardless of ownership and permissions. 1024638032Speter If a subroutine returns a fully qualified address, return it 1024738032Speter immediately instead of feeding it back into rewriting. 1024838032Speter This fixes a problem with mailertable lookups. 1024938032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1025038032Speter 1025164562Sgshapiro8.1B/8.1A 1993/06/12 1025238032Speter Serious bug fix: pattern matching backup algorithm stepped by 1025338032Speter two tokens in classes instead of one. Found by Claus 1025438032Speter Assmann at University of Kiel, Germany. 1025538032Speter 1025664562Sgshapiro8.1A/8.1A 1993/06/08 1025738032Speter Another mailertable fix.... 1025838032Speter 1025964562Sgshapiro8.1/8.1 1993/06/07 1026038032Speter 4.4BSD freeze.
