138032Speter SENDMAIL RELEASE NOTES 2182352Sgshapiro $Id: RELEASE_NOTES,v 8.1926 2008/05/03 03:34:26 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 9182352Sgshapiro8.14.3/8.14.3 2008/05/03 10182352Sgshapiro During ruleset processing the generation of a key for a map 11182352Sgshapiro lookup and the parsing of the default value was broken 12182352Sgshapiro for some macros, e.g., $|, which caused the BlankSub 13182352Sgshapiro character to be inserted into the workspace and thus 14182352Sgshapiro failures, e.g., rules that should have matched did not. 15182352Sgshapiro 8.14.2 caused a regression: it accessed (macro) storage which was 16182352Sgshapiro freed before. First instance of the problem reported by 17182352Sgshapiro Matthew Dillon of DragonFlyBSD; variations of the same 18182352Sgshapiro bug reported by Todd C. Miller of OpenBSD, Moritz 19182352Sgshapiro Jodeit, and Dave Hayes. 20182352Sgshapiro Improve pathname length checks for persistent host status. Patch 21182352Sgshapiro from Joerg Sonnenberger of DragonFlyBSD. 22182352Sgshapiro Reword misleading SMTP reply text for FEATURE(`badmx'). Problem 23182352Sgshapiro noted by Beth Halsema. 24182352Sgshapiro The read timeout was fixed to be Timeout.datablock if STARTTLS 25182352Sgshapiro was activated. This may cause problems if that value 26182352Sgshapiro is lowered from its default. Problem noted by Jens Elkner. 27182352Sgshapiro CONFIG: Using LOCAL_TLS_CLIENT caused the tls_client ruleset 28182352Sgshapiro to operate incorrectly. Problem found by Werner Wiethege. 29182352Sgshapiro LIBMILTER: Omitting some protocol steps via the xxfi_negotiate() 30182352Sgshapiro callback did not work properly. The patchlevel of 31182352Sgshapiro libmilter has been set to 1 so a milter can determine 32182352Sgshapiro whether libmilter contains this fix. 33182352Sgshapiro MAKEMAP: If a delimiter is specified (-t) use that also when 34182352Sgshapiro dumping a map. Patch from Todd C. Miller of OpenBSD. 35182352Sgshapiro Portability: 36182352Sgshapiro Add support for Darwin 9.x (Mac OS X 10.5). 37182352Sgshapiro Support shared libraries in Darwin 8 and 9. Patch from 38182352Sgshapiro Chris Behrens of Concentric. 39182352Sgshapiro Add support for SCO OpenServer 6, patch from Boyd Gerber. 40182352Sgshapiro DEVTOOLS: Clarify that confSHAREDLIBDIR requires a trailing path. 41182352Sgshapiro Added Files: 42182352Sgshapiro devtools/OS/Darwin.9.x 43182352Sgshapiro devtools/OS/OSR.i386 44182352Sgshapiro 45173340Sgshapiro8.14.2/8.14.2 2007/11/01 46173340Sgshapiro If a message was queued and it contained 8 bit characters in 47173340Sgshapiro a From: or To: header, then those characters could be 48173340Sgshapiro "mistaken" for internal control characters during a queue 49173340Sgshapiro run and trigger various consistency checks. Problem 50173340Sgshapiro noted by Neil Rickert of Northern Illinois University. 51173340Sgshapiro If MaxMimeHeaderLength is set to a value greater than 0 (which 52173340Sgshapiro it is by default) then even if the Linelimit parameter 53173340Sgshapiro is 0, sendmail corrupted in the non-transfer-encoding 54173340Sgshapiro case every MAXLINE-1 characters. Patch from John Gardiner 55173340Sgshapiro Myers of Proofpoint. 56173340Sgshapiro Setting the suboption DeliveryMode for DaemonPortOptions did not 57173340Sgshapiro work in earlier 8.14 versions. 58173340Sgshapiro Note: DeliveryMode=interactive is silently converted to 59173340Sgshapiro background if a milter can reject or delete a recipient. 60173340Sgshapiro Prior to 8.14 this happened only if milter could delete 61173340Sgshapiro recipients. 62173340Sgshapiro ClientRate should trigger when the limit was exceeded (as 63182352Sgshapiro documented), not when it was reached. Patch from 64173340Sgshapiro John Beck of Sun Microsystems. 65173340Sgshapiro Force a queue run for -qGqueuegroup even if no runners are 66173340Sgshapiro specified (R=0) and forking (F=f) is requested. 67173340Sgshapiro When multiple results are requested for a DNS map lookup 68173340Sgshapiro (-z and -Z), return only those that are relevant for 69173340Sgshapiro the query (not also those in the "additional section".) 70173340Sgshapiro If the message transfer time to sendmail (when acting as server) 71173340Sgshapiro exceeds Timeout.queuewarn or Timeout.queuereturn and 72173340Sgshapiro the message is refused (by a milter), sendmail previously 73173340Sgshapiro created a delivery status notification (DSN). Patch 74173340Sgshapiro from Doug Heath of The Hertz Corporation. 75173340Sgshapiro A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires 76173340Sgshapiro the MTA to deal with some input (i.e., "=") itself. 77173340Sgshapiro Problem noted by Eliot Lear. 78173340Sgshapiro sendmail counted a delivery as successful if PIPELINING is 79173340Sgshapiro compiled in but not offered by the server and the 80173340Sgshapiro delivery failed temporarily. Patch from Werner Wiethege. 81173340Sgshapiro If getting the result of an LDAP query times out then close the 82173340Sgshapiro map so it will be reopened on the next lookup. This 83173340Sgshapiro should help "failover" configurations that specify more 84173340Sgshapiro than one LDAP server. 85173340Sgshapiro If check_compat returns $#discard then a "savemail panic" could 86173340Sgshapiro be triggered under some circumstances (e.g., requiring 87173340Sgshapiro a system which does not have the compile time flag 88173340Sgshapiro HASFLOCK set). Based on patch by Motonori Nakamura 89173340Sgshapiro of National Institute of Informatics, Japan. 90173340Sgshapiro If a milter rejected a recipient, the count for nrcpts= in the 91173340Sgshapiro logfile entry might have been wrong. Problem found by 92173340Sgshapiro Petra Humann of TU Dresden. 93173340Sgshapiro If a milter invoked smfi_chgfrom() where ESMTP arguments are not 94173340Sgshapiro NULL, the message body was lost. Patch from Motonori 95173340Sgshapiro Nakamura of National Institute of Informatics, Japan. 96173340Sgshapiro sendmail(8) had a bogus space in -qGname. Patch from Peng Haitao. 97173340Sgshapiro CONTRIB: buildvirtuser: Preserve ownership and permissions when 98173340Sgshapiro replacing files. 99173340Sgshapiro CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when 100173340Sgshapiro reading the /etc/mail/virtusers/ directory. 101173340Sgshapiro CONTRIB: buildvirtuser: Emit warnings instead of exiting where 102173340Sgshapiro appropriate. 103173340Sgshapiro LIBMILTER: Fix ABI backwards compatibility so milters compiled 104173340Sgshapiro against an older libmilter.so shared library can use an 105173340Sgshapiro 8.14 libmilter.so shared library. 106173340Sgshapiro LIBMILTER: smfi_version() did not properly extract the patchlevel 107173340Sgshapiro from the version number, however, the returned value was 108173340Sgshapiro correct for the current libmilter version. 109173340Sgshapiro 110168515Sgshapiro8.14.1/8.14.1 2007/04/03 111168515Sgshapiro Even though a milter rejects a recipient the MTA will still keep 112168515Sgshapiro it in its list of recipients and deliver to it if the 113168515Sgshapiro transaction is accepted. This is a regression introduced 114168515Sgshapiro in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug 115168515Sgshapiro found by Andy Fiddaman. 116168515Sgshapiro The new DaemonPortOptions which begin with a lower case character 117168515Sgshapiro could not be set in 8.14.0. 118168515Sgshapiro If a server shut down the connection in response to a STARTTLS 119168515Sgshapiro command, sendmail would log a misleading error message 120168515Sgshapiro due to an internal inconsistency. Problem found by 121168515Sgshapiro Werner Wiethege. 122168515Sgshapiro Document how some sendmail.cf options change the behavior of mailq. 123168515Sgshapiro Noted by Paul Menchini of the North Carolina School of 124168515Sgshapiro Science and Mathematics. 125168515Sgshapiro CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce. 126168515Sgshapiro CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition 127168515Sgshapiro of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE 128168515Sgshapiro m4 options for setting MaxNOOPCommands and 129168515Sgshapiro SharedMemoryKeyFile. 130168515Sgshapiro CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4 131168515Sgshapiro options for setting Milter.macros.eoh and Milter.macros.data. 132168515Sgshapiro CONTRIB: Use flock() and fcntl() in qtool.pl if necessary. 133168515Sgshapiro Patch from Daniel Carroll of Mesa State College. 134168515Sgshapiro LIBMILTER: Make sure an unknown command does not affect the 135168515Sgshapiro currently available macros. Problem found by Andy Fiddaman. 136168515Sgshapiro LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option 137168515Sgshapiro negotiation. Problem reported by Bryan Costales. 138168515Sgshapiro LIBMILTER: Fix several minor errors in the documentation. 139168515Sgshapiro Patches from Bryan Costales. 140168515Sgshapiro PORTABILITY FIXES: 141168515Sgshapiro AIX 5.{1,2}: libsm/util.c failed to compile due to 142168515Sgshapiro redefinition of several macros, e.g., SIG_ERR. 143168515Sgshapiro Patch from Jim Pirzyk with assistance by Bob 144168515Sgshapiro Booth, University of Illinois at Urbana-Champaign. 145168515Sgshapiro Add support for QNX.6. Patch from Sean Boudreau of QNX 146168515Sgshapiro Software Systems. 147168515Sgshapiro New Files: 148168515Sgshapiro devtools/M4/depend/QNX6.m4 149168515Sgshapiro devtools/OS/QNX.6.x 150168515Sgshapiro include/sm/os/sm_os_qnx.h 151168515Sgshapiro 152168515Sgshapiro New Files added in 8.14.0, but not shown in the release notes entry: 153168515Sgshapiro libmilter/docs/smfi_chgfrom.html 154168515Sgshapiro libmilter/docs/smfi_version.html 155168515Sgshapiro 156168515Sgshapiro8.14.0/8.14.0 2007/01/31 157168515Sgshapiro Header field values are now 8 bit clean. Notes: 158168515Sgshapiro - header field names are still restricted to 7 bit. 159168515Sgshapiro - RFC 2822 allows only 7 bit (US-ASCII) characters in 160168515Sgshapiro headers. 161168515Sgshapiro Preserve spaces after the colon in a header. Previously, any 162168515Sgshapiro number of spaces after the colon would be changed to 163168515Sgshapiro exactly one space. 164168515Sgshapiro In some cases of deeply nested aliases/forwarding, mail can 165168515Sgshapiro be silently lost. Moreover, the MaxAliasRecursion 166168515Sgshapiro limit may be reached too early, e.g., the counter 167168515Sgshapiro may be off by a factor of 4 in case of a sequence of 168168515Sgshapiro .forward files that refer to others. Patch from 169168515Sgshapiro Motonori Nakamura of Kyoto University. 170168515Sgshapiro Fix a regression in 8.13.8: if InputMailFilters is set then 171168515Sgshapiro "sendmail -bs" can trigger an assertion because the 172168515Sgshapiro hostname of the client is undefined. It is now set 173168515Sgshapiro to "localhost" for the xxfi_connect() callback. 174168515Sgshapiro Avoid referencing a freed variable during cleanup when terminating. 175168515Sgshapiro Problem reported and diagnosed by Joe Maimon. 176168515Sgshapiro New option HeloName to set the name for the HELO/EHLO command. 177168515Sgshapiro Patch from Nik Clayton. 178168515Sgshapiro New option SoftBounce to issue temporary errors (4xy) instead of 179168515Sgshapiro permanent errors (5xy). This can be useful for testing. 180168515Sgshapiro New suboptions for DaemonPortOptions to set them individually 181168515Sgshapiro per daemon socket: 182168515Sgshapiro DeliveryMode DeliveryMode 183168515Sgshapiro refuseLA RefuseLA 184168515Sgshapiro delayLA DelayLA 185168515Sgshapiro queueLA QueueLA 186168515Sgshapiro children MaxDaemonChildren 187168515Sgshapiro New option -K for LDAP maps to replace %1 through %9 in the 188168515Sgshapiro lookup key with the LDAP escaped contents of the 189168515Sgshapiro arguments specified in the map lookup. Loosely based 190168515Sgshapiro on patch from Wolfgang Hottgenroth. 191168515Sgshapiro Log the time after which a greet_pause delay triggered. Patch 192168515Sgshapiro from Nik Clayton. 193168515Sgshapiro If a client is rejected via TCP wrapper or some other check 194168515Sgshapiro performed by validate_connection() (in conf.c) then do 195168515Sgshapiro not also invoke greet_pause. Problem noted by Jim Pirzyk 196168515Sgshapiro of the University of Illinois at Urbana-Champaign. 197168515Sgshapiro If a client terminates the SMTP connection during a pause 198168515Sgshapiro introduced by greet_pause, then a misleading message 199168515Sgshapiro was logged previously. Problem noted by Vernon Schryver 200168515Sgshapiro et.al., patch from Matej Vela. 201168515Sgshapiro New command "mstat" for control socket to provide "machine 202168515Sgshapiro readable" status. 203168515Sgshapiro New named config file rule check_eom which is called at the end 204168515Sgshapiro of a message, its parameter is the size of the message. 205168515Sgshapiro If the macro {addr_type} indicates that the current address 206168515Sgshapiro is a header address it also distinguishes between 207168515Sgshapiro recipient and sender addresses (as it is done for 208168515Sgshapiro envelope addresses). 209168515Sgshapiro When a macro is set in check_relay, then its value is accessible 210168515Sgshapiro by all transactions in the same SMTP session. 211168515Sgshapiro Increase size of key for ldap lookups to 1024 (MAXKEY). 212168515Sgshapiro New option MaxNOOPCommands to override default of 20 for the 213168515Sgshapiro number of "useless" commands before the SMTP server will 214168515Sgshapiro slow down responding. 215168515Sgshapiro New option SharedMemoryKeyFile: if shared memory support is 216168515Sgshapiro enabled, the MTA can be asked to select a shared memory 217168515Sgshapiro key itself by setting SharedMemoryKey to -1 and specifying 218168515Sgshapiro a file where to store the selected key. 219168515Sgshapiro Try to deal with open HTTP proxies that are used to send spam 220168515Sgshapiro by recognizing some commands from them. If the first command 221168515Sgshapiro from the client is GET, POST, CONNECT, or USER, then the 222168515Sgshapiro connection is terminated immediately. 223168515Sgshapiro New PrivacyOptions noactualrecipient to avoid putting 224168515Sgshapiro X-Actual-Recipient lines in DSNs revealing the actual 225168515Sgshapiro account that addresses map to. Patch from Dan Harkless. 226168515Sgshapiro New options B, z, and Z for DNS maps: 227168515Sgshapiro -B: specify a domain that is always appended to queries. 228168515Sgshapiro -z: specify the delimiter at which to cut off the result of 229168515Sgshapiro a query if it is too long. 230168515Sgshapiro -Z: specify the maximum number of entries to be concatenated 231168515Sgshapiro to form the result of a lookup. 232168515Sgshapiro New target "check" in the Makefile of libsm: instead of running tests 233168515Sgshapiro implicitly while building libsm, they must be explicitly 234168515Sgshapiro started by using "make check". 235168515Sgshapiro Fixed some inconsistent checks for NULL pointers that have been 236168515Sgshapiro reported by the SATURN tool which has been developed by 237168515Sgshapiro Isil Dillig and Thomas Dillig of Stanford University. 238168515Sgshapiro Fix a potential race condition caused by a signal handler for 239168515Sgshapiro terminated child processes. Problem noted by David F. Skoll. 240168515Sgshapiro When a milter deleted a recipient, that recipient could cause a 241168515Sgshapiro queue group selection. This has been disabled as it was not 242168515Sgshapiro intended. 243168515Sgshapiro New operator 'r' for the arith map to return a random number. 244168515Sgshapiro Patch from Motonori Nakamura of Kyoto University. 245168515Sgshapiro New compile time option MILTER_NO_NAGLE to turn off the Nagle 246168515Sgshapiro algorithm for communication with libmilter ("cork" on Linux), 247168515Sgshapiro which may improve the communication performance on some 248168515Sgshapiro operating systems. Patch from John Gardiner Myers of 249168515Sgshapiro Proofpoint. 250168515Sgshapiro If sendmail received input that contained a CR without subsequent LF 251168515Sgshapiro (thus violating RFC 2821 (2.3.7)), it could previously 252168515Sgshapiro generate an additional blank line in the output as the last 253168515Sgshapiro line. 254168515Sgshapiro Restarting persistent queue runners by sending a HUP signal to 255168515Sgshapiro the "queue control process" (QCP) works now. 256168515Sgshapiro Increase the length of an input line to 12288 to deal with 257168515Sgshapiro really long lines during SMTP AUTH negotiations. 258168515Sgshapiro Problem noted by Werner Wiethege. 259168515Sgshapiro If ARPANET mode (-ba) was selected STARTTLS would fail (due to 260168515Sgshapiro a missing initialization call for that case). Problem 261168515Sgshapiro noted by Neil Rickert of Northern Illinois University. 262168515Sgshapiro If sendmail is linked against a library that initializes Cyrus-SASL 263168515Sgshapiro before sendmail did it (such as libnss-ldap), then SMTP AUTH 264168515Sgshapiro could fail for the sendmail client. A patch by Moritz Both 265168515Sgshapiro works around the API design flaw of Cyrus-SASLv2. 266168515Sgshapiro CONFIG: Make it possible to unset the StatusFile option by 267168515Sgshapiro undefining STATUS_FILE. By not setting StatusFile, 268168515Sgshapiro the MTA will not attempt to open a statistics file on 269168515Sgshapiro each delivery. 270168515Sgshapiro CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP 271168515Sgshapiro clients whose IP address does not have proper reverse DNS. 272168515Sgshapiro Contributed by Neil Rickert of Northern Illinois University 273168515Sgshapiro and John Beck of Sun Microsystems. 274168515Sgshapiro CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP 275168515Sgshapiro clients which provide a HELO/EHLO argument which is either 276168515Sgshapiro unqualified, or is one of our own names (i.e., the server 277168515Sgshapiro name instead of the client name). Contributed by Neil 278168515Sgshapiro Rickert of Northern Illinois University and John Beck of 279168515Sgshapiro Sun Microsystems. 280168515Sgshapiro CONFIG: New FEATURE(`badmx') to reject envelope sender addresses 281168515Sgshapiro (MAIL) whose domain part resolves to a "bad" MX record. 282168515Sgshapiro Based on contribution from William Dell Wisner. 283168515Sgshapiro CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override 284168515Sgshapiro the maximum line length of the smtp mailers. 285168515Sgshapiro CONFIG: New option `relaytofulladdress' for FEATURE(`access_db') 286168515Sgshapiro to allow entries in the access map to be of the form 287168515Sgshapiro To:user@example.com RELAY 288168515Sgshapiro CONFIG: New subsuboptions eoh and data to specify the list of 289168515Sgshapiro macros a milter should receive at those stages in the 290168515Sgshapiro SMTP dialogue. 291168515Sgshapiro CONFIG: New option confHELO_NAME for HeloName to set the name 292168515Sgshapiro for the HELO/EHLO command. 293168515Sgshapiro CONFIG: dnsbl and enhdnsbl can now also discard or quarantine 294168515Sgshapiro messages by using those values as second argument. 295168515Sgshapiro Patches from Nelson Fung. 296168515Sgshapiro CONTRIB: cidrexpand uses a hash symbol as comment character and 297168515Sgshapiro ignores everything after it unless it is in quotes or 298168515Sgshapiro preceeded by a backslash. 299168515Sgshapiro DEVTOOLS: New macro confMKDIR: if set to a program that creates 300168515Sgshapiro directories, then it used for "make install" to create 301168515Sgshapiro the required installation directories. 302168515Sgshapiro DEVTOOLS: New macro confCCLINK to specify the linker to use for 303168515Sgshapiro executables (defaults to confCC). 304168515Sgshapiro LIBMILTER: A new version of the milter API has been created that 305168515Sgshapiro has several changes which are listed below and documented 306168515Sgshapiro in the webpages reachable via libmilter/docs/index.html. 307168515Sgshapiro LIBMILTER: The meaning of the version macro SMFI_VERSION has been 308168515Sgshapiro changed. It now refers only to the version of libmilter, 309168515Sgshapiro not to the protocol version (which is used only internally, 310168515Sgshapiro it is not user/milter-programmer visible). Additionally, 311168515Sgshapiro a version function smfi_version() has been introduced such 312168515Sgshapiro that a milter program can check the libmilter version also 313168515Sgshapiro at runtime which is useful if a shared library is used. 314168515Sgshapiro LIBMILTER: A new callback xxfi_negotiate() can be used to 315168515Sgshapiro dynamically (i.e., at runtime) determine the available 316168515Sgshapiro protocol actions and features of the MTA and also to 317168515Sgshapiro specify which of these a milter wants to use. This allows 318168515Sgshapiro for more flexibility than hardcoding these flags in the 319168515Sgshapiro xxfi_flags field of the smfiDesc structure. 320168515Sgshapiro LIBMILTER: A new callback xxfi_data() is available so milters 321168515Sgshapiro can act on the DATA command. 322168515Sgshapiro LIBMILTER: A new callback xxfi_unknown() is available so milters 323168515Sgshapiro can receive also unknown SMTP commands. 324168515Sgshapiro LIBMILTER: A new return code SMFIS_NOREPLY has been added which 325168515Sgshapiro can be used by the xxfi_header() callback provided the 326168515Sgshapiro milter requested the SMFIP_NOHREPL protocol action. 327168515Sgshapiro LIBMILTER: The new return code SMFIS_SKIP can be used in the 328168515Sgshapiro xxfi_body() callback to skip over further body chunks 329168515Sgshapiro and directly advance to the xxfi_eom() callback. This 330168515Sgshapiro is useful if a milter can make a decision based on the 331168515Sgshapiro body chunks it already received without reading the entire 332168515Sgshapiro rest of the body and the milter wants to invoke functions 333168515Sgshapiro that are only available from the xxfi_eom() callback. 334168515Sgshapiro LIBMILTER: A new function smfi_addrcpt_par() can be used to add 335168515Sgshapiro new recipients including ESMTP parameters. 336168515Sgshapiro LIBMILTER: A new function smfi_chgfrom() can be used to change the 337168515Sgshapiro envelope sender including ESMTP parameters. 338168515Sgshapiro LIBMILTER: A milter can now request to be informed about rejected 339168515Sgshapiro recipients (RCPT) too. This requires to set the protocol 340168515Sgshapiro flag SMFIP_RCPT_REJ during option negotiation. Whether 341168515Sgshapiro a RCPT has been rejected can be checked by comparing the 342168515Sgshapiro value of the macro {rcpt_mailer} with "error". 343168515Sgshapiro LIBMILTER: A milter can now override the list of macros that it 344168515Sgshapiro wants to receive from the MTA for each protocol step 345168515Sgshapiro by invoking the function smfi_setsymlist() during option 346168515Sgshapiro negotiation. 347168515Sgshapiro LIBMILTER: A milter can receive header field values with all 348168515Sgshapiro leading spaces by requesting the SMFIP_HDR_LEADSPC 349168515Sgshapiro protocol action. Also, if the flag is set then the MTA 350168515Sgshapiro does not add a leading space to headers that are added, 351168515Sgshapiro inserted, or replaced. 352168515Sgshapiro LIBMILTER: If a milter sets the reply code to "421" for the HELO 353168515Sgshapiro callback, the SMTP server will terminate the SMTP session 354168515Sgshapiro with that error to match the behavior of all other callbacks. 355168515Sgshapiro New Files: 356168515Sgshapiro cf/feature/badmx.m4 357168515Sgshapiro cf/feature/block_bad_helo.m4 358168515Sgshapiro cf/feature/require_rdns.m4 359168515Sgshapiro devtools/M4/UNIX/check.m4 360168515Sgshapiro include/sm/misc.h 361168515Sgshapiro include/sm/sendmail.h 362168515Sgshapiro include/sm/tailq.h 363168515Sgshapiro libmilter/docs/smfi_addrcpt_par.html 364168515Sgshapiro libmilter/docs/smfi_setsymlist.html 365168515Sgshapiro libmilter/docs/xxfi_data.html 366168515Sgshapiro libmilter/docs/xxfi_negotiate.html 367168515Sgshapiro libmilter/docs/xxfi_unknown.html 368168515Sgshapiro libmilter/example.c 369168515Sgshapiro libmilter/monitor.c 370168515Sgshapiro libmilter/worker.c 371168515Sgshapiro libsm/memstat.c 372168515Sgshapiro libsm/t-memstat.c 373168515Sgshapiro libsm/t-qic.c 374168515Sgshapiro libsm/util.c 375168515Sgshapiro sendmail/daemon.h 376168515Sgshapiro sendmail/map.h 377168515Sgshapiro 378161389Sgshapiro8.13.8/8.13.8 2006/08/09 379161389Sgshapiro Fix a regression in 8.13.7: if shared memory is activated, then 380161389Sgshapiro the server can erroneously report that there is 381161389Sgshapiro insufficient disk space. Additionally make sure that 382161389Sgshapiro an internal variable is set properly to avoid those 383161389Sgshapiro misleading errors. Based on patch from Steve Hubert 384161389Sgshapiro of University of Washington. 385161389Sgshapiro Fix a regression in 8.13.7: the PidFile could be removed after 386161389Sgshapiro the process that forks the daemon exited, i.e., if 387161389Sgshapiro sendmail -bd is invoked. Problem reported by Kan Sasaki 388161389Sgshapiro of Fusion Communications Corp. and Werner Wiethege. 389161389Sgshapiro Avoid opening qf files if QueueSortOrder is "none". Patch from 390161389Sgshapiro David F.

However, 397161389Sgshapiro this did not match the documentation of the function, hence 398161389Sgshapiro it has been changed to {client_name}. See doc/op/op.* 399161389Sgshapiro about these macros. 400161389Sgshapiro 401159609Sgshapiro8.13.7/8.13.7 2006/06/14 402159609Sgshapiro A malformed MIME structure with many parts can cause sendmail to 403159609Sgshapiro crash while trying to send a mail due to a stack overflow, 404159609Sgshapiro e.g., if the stack size is limited (ulimit -s). This 405159609Sgshapiro happens because the recursion of the function mime8to7() 406159609Sgshapiro was not restricted. The function is called for MIME 8 to 407159609Sgshapiro 7 bit conversion and also to enforce MaxMimeHeaderLength. 408159609Sgshapiro To work around this problem, recursive calls are limited to 409159609Sgshapiro a depth of MAXMIMENESTING (20); message content after this 410159609Sgshapiro limit is treated as opaque and is not checked further. 411159609Sgshapiro Problem noted by Frank Sheiness. 412159609Sgshapiro The changes to the I/O layer in 8.13.6 caused a regression for 413159609Sgshapiro SASL mechanisms that use the security layer, e.g., 414159609Sgshapiro DIGEST-MD5. Problem noted by Robert Stampfli. 415159609Sgshapiro If a timeout occurs while reading a message (during the DATA phase) 416159609Sgshapiro a df file might have been left behind in the queue. 417159609Sgshapiro This was another side effect of the changes to the I/O 418159609Sgshapiro layer made in 8.13.6. 419159609Sgshapiro Several minor problems have been fixed that were found by a 420159609Sgshapiro Coverity scan of sendmail 8 as part of the NetBSD 421159609Sgshapiro distribution. See http://scan.coverity.com/ 422159609Sgshapiro Note: the scan generated also a lot of "false positives", 423159609Sgshapiro e.g., "error" reports about situations that cannot happen. 424159609Sgshapiro Most of those code places are marked with lint(1) comments 425159609Sgshapiro like NOTREACHED, but Coverity does not understand those. 426159609Sgshapiro Hence an explicit assertion has been added in some cases 427159609Sgshapiro to avoid those false positives. 428159609Sgshapiro If the start of the sendmail daemon fails due to a configuration 429159609Sgshapiro error then in some cases shared memory segments or pid 430159609Sgshapiro files were not removed. 431159609Sgshapiro If DSN support is disabled via access_db, then related ESMTP 432159609Sgshapiro parameters for MAIL and RCPT should be rejected. Problem 433159609Sgshapiro reported by Akihiro Sagawa. 434159609Sgshapiro Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding 435159609Sgshapiro bug work-around. Hence if sendmail is linked against 436159609Sgshapiro either of these versions and compression is available, 437159609Sgshapiro the padding bug work-around is turned off.

Problem noted by Mark Tranchant. 624141858Sgshapiro 625141858Sgshapiro8.13.2/8.13.2 2004/12/15 626141858Sgshapiro Do not split the first header even if it exceeds the internal 627141858Sgshapiro buffer size. Previously a part of such a header would 628141858Sgshapiro end up in the body of the message. Problem noted by 629141858Sgshapiro Simple Nomad of BindView. 630141858Sgshapiro Do not complain about "cataddr: string too long" when checking 631141858Sgshapiro headers that do not contain RFC 2822 addresses. 632141858Sgshapiro Problem noted by Rich Graves of Brandeis University. 633141858Sgshapiro If a server returns a 421 reply to the RSET command between 634141858Sgshapiro message deliveries, do not attempt to deliver any more 635141858Sgshapiro messages on that connection. This prevents bogus "Bad 636141858Sgshapiro file number" recipient status. Problem noted by 637141858Sgshapiro Allan E Johannesen of Worcester Polytechnic Institute. 638141858Sgshapiro Allow trailing white space in EHLO command as recommended by RFC 639141858Sgshapiro 2821. Problem noted by Ralph Santagato of SBC Services. 640141858Sgshapiro Deal with clients which use AUTH but negotiate a smaller buffer size 641141858Sgshapiro for data exchanges than the value used by sendmail, e.g., 642141858Sgshapiro Cyrus IMAP lmtp server. Based on patch by Jamie Clark. 643141858Sgshapiro When passing ESMTP arguments for RCPT to a milter, do not cut 644141858Sgshapiro them off at a comma. Problem noted by Krzysztof Oledzki. 645141858Sgshapiro Add more logging to milter change header functions to 646141858Sgshapiro complement existing logging.

From John Beck of Sun Microsystems. 683132943Sgshapiro Fix SuperSafe=PostMilter behavior when a milter replaces a body 684132943Sgshapiro but the data file is not yet stored on disk because it is 685132943Sgshapiro smaller than the size of the memory buffer. Problem noted 686132943Sgshapiro by David Russell. 687132943Sgshapiro Fix certificate revocation list support; if a CRL was specified 688132943Sgshapiro but the other side presented a cert that was signed by 689132943Sgshapiro a different (trusted) CA than the one which issued the CRL, 690132943Sgshapiro verification would always fail. Problem noted by Al Smith. 691132943Sgshapiro Run mailer programs as the RunAsUser when RunAsUser is set and 692132943Sgshapiro the F=S mailer flag is set without a U= mailer equate. 693132943Sgshapiro Problem noted by John Gardiner Myers of Proofpoint. 694132943Sgshapiro ${nbadrcpts} was off by one if BadRcptThrottle is zero. 695132943Sgshapiro Patch from Sung-hoon Choi of DreamWiz Inc. 696132943Sgshapiro CONFIG: Emit a warning if FEATURE(`access_db') is used after 697132943Sgshapiro FEATURE(`greet_pause') because then the latter will not 698132943Sgshapiro use the access map.

Problem found 727132943Sgshapiro by Christof Haerens, patch from Per Hedeland. 728132943Sgshapiro Add support for LDAP recursion based on types given to attribute 729132943Sgshapiro specifications in an LDAP map definition. This allows 730132943Sgshapiro LDAP queries to return a new query, a DN, or an LDAP 731132943Sgshapiro URL which will in turn be queried. See the ``LDAP 732132943Sgshapiro Recursion'' section of doc/op/op.me for more information. 733132943Sgshapiro Based on patch from Andrew Baucom. 734132943Sgshapiro Extend the default LDAP specifications for AliasFile 735132943Sgshapiro (O AliasFile=ldap:) and file classes (F{X}@LDAP) to 736132943Sgshapiro include support for LDAP recursion via new attributes. 737132943Sgshapiro See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section 738132943Sgshapiro of cf/README for more information. 739132943Sgshapiro New option for LDAP maps: the -w option allows you to specify the 740132943Sgshapiro LDAP API/protocol version to use. The default depends on 741132943Sgshapiro the LDAP library. 742132943Sgshapiro New option for LDAP maps: the -H option allows you to specify an 743132943Sgshapiro LDAP URI instead of specifying the LDAP server via -h host 744132943Sgshapiro and -p port. This also allows for the use of LDAP over 745132943Sgshapiro SSL and connections via named sockets if your LDAP 746132943Sgshapiro library supports it. 747132943Sgshapiro New compile time flag SM_CONF_LDAP_INITIALIZE: set this if 748132943Sgshapiro ldap_initialize(3) is available (and LDAPMAP is set). 749132943Sgshapiro If MaxDaemonChildren is set and a command is repeated too often 750132943Sgshapiro during a SMTP session then terminate it just like it is 751132943Sgshapiro done for too many bad SMTP commands. 752132943Sgshapiro Basic connection rate control support has been added: the daemon 753132943Sgshapiro maintains the number of incoming connections per client 754132943Sgshapiro IP address and total in the macros {client_rate} and 755132943Sgshapiro {total_rate}, respectively. These macros can be used 756132943Sgshapiro in the cf file to impose connection rate limits. 757132943Sgshapiro A new option ConnectionRateWindowSize (default: 60s) 758132943Sgshapiro determines the length of the interval for which the 759132943Sgshapiro number of connections is stored. Based on patch from 760132943Sgshapiro Jose Marcio Martins da Cruz, Ecole des Mines de Paris. 761132943Sgshapiro Add optional protection from open proxies and SMTP slammers which 762132943Sgshapiro send SMTP traffic without waiting for the SMTP greeting. 763132943Sgshapiro If enabled by the new ruleset greet_pause (see 764132943Sgshapiro FEATURE(`greet_pause')), sendmail will wait the specified 765132943Sgshapiro amount of time before sending the initial 220 SMTP 766132943Sgshapiro greeting. If any traffic is received before then, a 554 767132943Sgshapiro SMTP response is sent and all SMTP commands are rejected 768132943Sgshapiro during that connection. 769132943Sgshapiro If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP 770132943Sgshapiro server could sleep for a very long time. Fix based on 771132943Sgshapiro patch from Tadashi Kobayashi of IIJ. 772132943Sgshapiro Fix a potential memory leak in persistent queue runners if the 773132943Sgshapiro number of entries in the queue exceeds the limit of jobs. 774132943Sgshapiro Problem noted by Steve Hubert of University of Washington. 775132943Sgshapiro Do not use 4.7.1 as enhanced status code because some broken systems 776132943Sgshapiro misinterpret it as a permanent error. 777132943Sgshapiro New value for SuperSafe: PostMilter which will delay fsync() until 778132943Sgshapiro all milters accepted the mail. This can increase 779132943Sgshapiro performance if many mails are rejected by milters due to 780132943Sgshapiro body scans. Based on patch from David F. Skoll. 781132943Sgshapiro New macro {msg_id} which contains the value of the Message-Id: 782132943Sgshapiro header, whether provided by the client or generated by 783132943Sgshapiro sendmail. 784132943Sgshapiro New macro {client_connections} which contains the number of open 785132943Sgshapiro connections in the SMTP server for the client IP address. 786132943Sgshapiro Based on patch from Jose Marcio Martins da Cruz, Ecole des 787132943Sgshapiro Mines de Paris. 788132943Sgshapiro sendmail will now remove its pidfile when it exits. This was done 789132943Sgshapiro to prevent confusion caused by running sendmail stop 790132943Sgshapiro scripts two or more times, where the second and subsequent 791141858Sgshapiro runs would report misleading error messages about sendmail's 792132943Sgshapiro pid no longer existing. See section 1.3.15 of doc/op/op.me 793132943Sgshapiro for a discussion of the implications of this, including 794132943Sgshapiro how to correct broken scripts which may have depended on 795132943Sgshapiro the old behavior. From John Beck of Sun Microsystems. 796132943Sgshapiro Support per-daemon input filter lists which override the default 797132943Sgshapiro filter list specified in InputMailFilters. The filters 798132943Sgshapiro can be listed in the I= equate of DaemonPortOptions. 799132943Sgshapiro Do not add all domain prefixes of the hostname to class 'w'. If 800132943Sgshapiro your configuration relies on this behavior, you have to 801132943Sgshapiro add those names to class 'w' yourself. Problem noted 802132943Sgshapiro by Sander Eerkes. 803132943Sgshapiro Support message quarantining in the mail queue. Quarantined 804132943Sgshapiro messages are not run on normal queue displays or runs 805132943Sgshapiro unless specifically requested with -qQ. Quarantined queue 806132943Sgshapiro files are named with an hf prefix instead of a qf prefix. 807132943Sgshapiro The -q command line option now can specify which queue to display 808132943Sgshapiro or run. -qQ operates on quarantined queue items. -qL 809132943Sgshapiro operates on lost queue items. 810132943Sgshapiro Restricted mail queue runs and displays can be done based on the 811132943Sgshapiro quarantined reason using -qQtext to run or display 812132943Sgshapiro quarantined items if the quarantine reason contains the 813132943Sgshapiro given text. Similarly, -q!Qtext will run or display 814132943Sgshapiro quarantined items which do not have the given text in the 815132943Sgshapiro quarantine reason. 816132943Sgshapiro Items in the queue can be quarantined or unquarantined using the 817132943Sgshapiro new -Q option. See doc/op/op.me for more information. 818132943Sgshapiro When displaying the quarantine mailq with 'mailq -qQ', the 819132943Sgshapiro quarantine reason is shown in a new line prefixed by 820132943Sgshapiro "QUARANTINE:". 821132943Sgshapiro A new error code for the $#error mailer, $@ quarantine, can be used 822132943Sgshapiro to quarantine messages in check_* (except check_compat) and 823132943Sgshapiro header check rulesets. The $: of the mailer triplet will 824132943Sgshapiro be used for the quarantine reason. 825132943Sgshapiro Add a new quarantine count to the mailstats collected. 826132943Sgshapiro Add a new macro ${quarantine} which is the quarantine reason for a 827132943Sgshapiro message if it is quarantined. 828132943Sgshapiro New map type "socket" for a trivial query protocol over UNIX domain 829132943Sgshapiro or TCP sockets (requires compile time option SOCKETMAP). 830132943Sgshapiro See sendmail/README and doc/op/op.me for details as well as 831132943Sgshapiro socketmapServer.pl and socketmapClient.pl in contrib. 832132943Sgshapiro Code donated by Bastiaan Bakker of LifeLine Networks. 833132943Sgshapiro Define new macro ${client_ptr} which holds the result of the PTR 834132943Sgshapiro lookup for the client IP address. Note: this is the same 835132943Sgshapiro as ${client_name} if and only if ${client_resolve} is OK. 836132943Sgshapiro Add a new macro ${nbadrcpts} which contains the number of bad 837132943Sgshapiro recipients received so far in a transaction. 838132943Sgshapiro Call check_relay with the value of ${client_name} to deal with bogus 839132943Sgshapiro DNS entries. See also FEATURE(`use_client_ptr'). Problem 840132943Sgshapiro noted by Kai Schlichting. 841132943Sgshapiro Treat Delivery-Receipt-To: headers the same as Return-Receipt-To: 842132943Sgshapiro headers (turn them into DSNs). Delivery-Receipt-To: is 843132943Sgshapiro apparently used by SIMS (Sun Internet Mail System). 844132943Sgshapiro Enable connection caching for LPC mailers. Patch from Christophe 845132943Sgshapiro Wolfhugel of France Telecom Oleane. 846132943Sgshapiro Do not silently truncate long strings in address rewriting. 847132943Sgshapiro Add support for Cyrus SASL version 2. From Kenneth Murchison of 848132943Sgshapiro Oceana Matrix Ltd. 849132943Sgshapiro Add a new AuthOption=m flag to require the use of mechanisms which 850132943Sgshapiro support mutual authentication. From Kenneth Murchison of 851132943Sgshapiro Oceana Matrix Ltd. 852132943Sgshapiro Fix logging of TLS related problems (introduced in 8.12.11). 853132943Sgshapiro The macros {auth_author} and {auth_authen} are stored in xtext 854132943Sgshapiro format just like the STARTTLS related macros to avoid 855132943Sgshapiro problems with parsing them. Problem noted by Pierangelo 856132943Sgshapiro Masarati of SysNet s.n.c. 857132943Sgshapiro New option AuthRealm to set the authentication realm that is 858132943Sgshapiro passed to the Cyrus SASL library. Patch from Gary Mills 859132943Sgshapiro of the University of Manitoba. 860132943Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS verification was 861132943Sgshapiro successful, otherwise relaying would be allowed if 862132943Sgshapiro EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS 863132943Sgshapiro is active. 864132943Sgshapiro Add basic support for certificate revocation lists. Note: if a 865132943Sgshapiro CRLFile is specified but the file is unusable, STARTTLS 866132943Sgshapiro is disabled. Based on patch by Ralf Hornik. 867132943Sgshapiro Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms 868132943Sgshapiro DIGEST-MD5 and LOGIN. 869132943Sgshapiro Write pid to file also if sendmail only acts as persistent queue 870132943Sgshapiro runner. Proposed by Gary Mills of the University of Manitoba. 871132943Sgshapiro Keep daemon pid file(s) locked so other daemons don't try to 872132943Sgshapiro overwrite each other's pid files. 873132943Sgshapiro Increase maximum length of logfile fields for {cert_subject} and 874132943Sgshapiro {cert_issuer} from 128 to 256. Requested by Christophe 875132943Sgshapiro Wolfhugel of France Telecom. 876132943Sgshapiro Log the TLS verification message on the STARTTLS= log line at 877132943Sgshapiro LogLevel 12 or higher. 878132943Sgshapiro If the MSP is invoked with the verbose option (-v) then it will 879132943Sgshapiro try to use the SMTP command VERB to propagate this option 880132943Sgshapiro to the MTA which in turn will show the delivery just like 881132943Sgshapiro it was done before the default 8.12 separation of MSP and 882132943Sgshapiro MTA. Based on patch by Per Hedeland. 883132943Sgshapiro If a daemon is refusing connections for longer than the time specified 884132943Sgshapiro by the new option RejectLogInterval (default: 3 hours) due 885132943Sgshapiro to high load, log this information. Patch from John Beck 886132943Sgshapiro of Sun Microsystems. 887132943Sgshapiro Remove the ability for non-trusted users to raise the value of 888132943Sgshapiro CheckpointInterval on the command line. 889132943Sgshapiro New mailer flag 'B' to strip leading backslashes, which is a 890132943Sgshapiro subset of the functionality of the 's' flag. 891132943Sgshapiro New mailer flag 'W' to ignore long term host status information. 892132943Sgshapiro Patch from Juergen Georgi of RUS University of Stuttgart. 893132943Sgshapiro Enable generic mail filter API (milter) by default. To turn 894132943Sgshapiro it off, add -DMILTER=0 to the compile time options. 895132943Sgshapiro An internal SMTP session discard flag was lost after an RSET/HELO/EHLO 896132943Sgshapiro causing subsequent messages to be sent instead of being 897132943Sgshapiro discarded. This also caused milter callbacks to be called 898132943Sgshapiro out of order after the SMTP session was reset. 899132943Sgshapiro New option RequiresDirfsync to turn off the compile time flag 900132943Sgshapiro REQUIRES_DIR_FSYNC at runtime. See sendmail/README for 901132943Sgshapiro further information. 902132943Sgshapiro New command line option -D logfile to send debug output to 903132943Sgshapiro the indicated log file instead of stdout. 904132943Sgshapiro Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control 905132943Sgshapiro queue return and warning times for delivery status 906132943Sgshapiro notifications. 907132943Sgshapiro New queue sort order option: 'n'one for not sorting the queue entries 908132943Sgshapiro at all. 909132943Sgshapiro Several more return values for ruleset srv_features have been added 910132943Sgshapiro to enable/disable certain features in the server per 911132943Sgshapiro connection. See doc/op/op.me for details. 912132943Sgshapiro Support for SMTP over SSL (smtps), activated by Modifier=s 913132943Sgshapiro for DaemonPortOptions. 914132943Sgshapiro Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when 915132943Sgshapiro trying to canonify hostnames. Suggested by Neil Rickert 916132943Sgshapiro of Northern Illinois University. 917132943Sgshapiro Add support for a fallback smart host (option FallbackSmartHost) to 918132943Sgshapiro be tried as a last resort after all other fallbacks. This 919132943Sgshapiro is designed for sites with partial DNS (e.g., an accurate 920132943Sgshapiro view of inside the company, but an incomplete view of 921132943Sgshapiro outside). From John Beck of Sun Microsystems. 922132943Sgshapiro Enable timeout for STARTTLS even if client does not start the TLS 923132943Sgshapiro handshake. Based on patch by Andrey J.

Patch from 925132943Sgshapiro Mark Roth of the University of Illinois at Urbana-Champaign. 926132943Sgshapiro libphclient is version 1.2.x by default, if version 1.1.x is required 927132943Sgshapiro then compile with -DNPH_VERSION=10100. Patch from Mark Roth 928132943Sgshapiro of the University of Illinois at Urbana-Champaign. 929132943Sgshapiro Add Milter.macros.eom, allowing macros to be sent to milter 930132943Sgshapiro applications for use in the xxfi_eom() callback. 931132943Sgshapiro New macro {time} which contains the output of the time(3) function, 932132943Sgshapiro i.e., the number of seconds since 0 hours, 0 minutes, 933132943Sgshapiro 0 seconds, January 1, 1970, Coordinated Universal Time (UTC). 934132943Sgshapiro If check_relay sets the reply code to "421" the SMTP server will 935132943Sgshapiro terminate the SMTP session with a 421 error message. 936132943Sgshapiro Get rid of dead code that tried to access the environment variable 937132943Sgshapiro HOSTALIASES. 938132943Sgshapiro Deprecate the use of ErrorMode=write. To enable this in 8.13 939132943Sgshapiro compile with -DUSE_TTYPATH=1. 940132943Sgshapiro Header check rulesets using $>+ (do not strip comments) will get 941132943Sgshapiro the header value passed in without balancing quotes, 942132943Sgshapiro parentheses, and angle brackets. Based on patch from 943132943Sgshapiro Oleg Bulyzhin. 944132943Sgshapiro Do not complain and fix up unbalanced quotes, parentheses, and 945132943Sgshapiro angle brackets when reading in rulesets. This allows 946132943Sgshapiro rules to be written for header checks to catch strings 947132943Sgshapiro that contain quotes, parentheses, and/or angle brackets. 948132943Sgshapiro Based on patch from Oleg Bulyzhin. 949132943Sgshapiro Do not close socket when accept(2) in the daemon encounters 950132943Sgshapiro some temporary errors like ECONNABORTED. 951132943Sgshapiro Added list of CA certificates that are used by members of the 952132943Sgshapiro sendmail consortium, see CACerts. 953132943Sgshapiro Portability: 954132943Sgshapiro Two new compile options have been added: 955132943Sgshapiro HASCLOSEFROM System has closefrom(3). 956132943Sgshapiro HASFDWALK System has fdwalk(3). 957132943Sgshapiro Based on patch from John Beck of Sun Microsystems. 958132943Sgshapiro The Linux kernel version 2.4 series has a broken flock() so 959132943Sgshapiro change to using fcntl() locking until they can fix 960132943Sgshapiro it. Be sure to update other sendmail related 961132943Sgshapiro programs to match locking techniques. 962132943Sgshapiro New compile time option NEEDINTERRNO which should be set 963132943Sgshapiro if <errno.h> does not declare errno itself. 964132943Sgshapiro Support for UNICOS/mk and UNICOS/mp added, some changes for 965132943Sgshapiro UNICOS. Patches contributed by Aaron Davis and 966132943Sgshapiro Brian Ginsbach, Cray Inc., and Manu Mahonen of 967132943Sgshapiro Center for Scientific Computing. 968132943Sgshapiro Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a.

This is useful for 1003132943Sgshapiro rejections based on the unverified hostname of client, 1004132943Sgshapiro which turns on the same behavior as in earlier sendmail 1005132943Sgshapiro versions when delay_checks was not in use. See also entry 1006132943Sgshapiro above about check_relay being invoked with ${client_name}. 1007132943Sgshapiro CONFIG: New option confREJECT_LOG_INTERVAL to specify the log 1008132943Sgshapiro interval when refusing connections for this long. 1009132943Sgshapiro CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases 1010132943Sgshapiro this requires a change in a mc file. Requested by 1011132943Sgshapiro Ted Roberts of Electronic Data Systems. 1012132943Sgshapiro CONFIG: New option confAUTH_REALM to set the authentication realm 1013132943Sgshapiro that is passed to the Cyrus SASL library.

Problem noted by Kevin 154298841Sgshapiro A. McGrail of Peregrine Hardware. 154398841Sgshapiro NOTE: Linux appears to have broken flock() again. Unless 154498841Sgshapiro the bug is fixed before sendmail 8.13 is shipped, 154598841Sgshapiro 8.13 will change the default locking method to 154698841Sgshapiro fcntl() for Linux kernel 2.4 and later. You may 154798841Sgshapiro want to do this in 8.12 by compiling with 154898841Sgshapiro -DHASFLOCK=0. Be sure to update other sendmail 154998841Sgshapiro related programs to match locking techniques. 155098841Sgshapiro 155198121Sgshapiro8.12.4/8.12.4 2002/06/03 155298121Sgshapiro SECURITY: Inherent limitations in the UNIX file locking model 155398121Sgshapiro can leave systems open to a local denial of service 155498121Sgshapiro attack.

In previous versions this could cause mail 164794334Sgshapiro not to be delivered if a queue file is repeatedly moved 164894334Sgshapiro by an external process whenever sendmail moved it back 164994334Sgshapiro into the right place. Some precautions have been taken 165094334Sgshapiro to avoid moving queue files if not really necessary. 165194334Sgshapiro sendmail may use links to refer to queue files and it 165294334Sgshapiro may store the path of data files in queue files. Hence 165394334Sgshapiro queue files should not be moved unless those internals 165494334Sgshapiro are understood and the integrity of the files is not 165594334Sgshapiro compromised. Problem noted by Anne Bennett of Concordia 165694334Sgshapiro University. 165794334Sgshapiro If an error mail is created, and the mail is split across different 165894334Sgshapiro queue directories, and SuperSafe is off, then write the mail 165994334Sgshapiro to disk before splitting it, otherwise an assertion is 166094334Sgshapiro triggered. Problem tracked down by Henning Schmiedehausen 166194334Sgshapiro of INTERMETA. 166294334Sgshapiro Fix possible race condition that could cause sendmail to forget 166394334Sgshapiro running queues.

Problem noted by Jon 170294334Sgshapiro Lusky of ISS Atlanta. 170394334Sgshapiro Avoid leaving behind stray transcript (xf) files if multiple queue 170494334Sgshapiro directories are used and mail is sent to a mailing list 170594334Sgshapiro which has an owner- alias. Problem noted by Anne Bennett 170694334Sgshapiro of Concordia University. 170794334Sgshapiro Fix class map parsing code if optional key is specified. Problem 170894334Sgshapiro found by Mario Nigrovic. 170994334Sgshapiro The SMTP daemon no longer tries to fix up improperly dot-stuffed 171094334Sgshapiro incoming messages. A leading dot is always stripped by the 171194334Sgshapiro SMTP receiver regardless of whether or not it is followed by 171294334Sgshapiro another dot. Problem noted by Jordan Ritter of darkridge.com. 171394334Sgshapiro Fix corruption when doing automatic MIME 7-bit quoted-printable or 171494334Sgshapiro base64 encoding to 8-bit text. Problem noted by Mark 171594334Sgshapiro Elvers. 171694334Sgshapiro Correct the statistics gathered for total number of connections. 171794334Sgshapiro Instead of being the exact same number as the total number 171894334Sgshapiro of messages (T line in mailstats) it now represents the 171994334Sgshapiro total number of TCP connections. 172094334Sgshapiro Be more explicit about syntax errors in addresses, especially 172194334Sgshapiro non-ASCII characters, and properly create DSNs if necessary. 172294334Sgshapiro Problem noted by Leena Heino of the University of Tampere. 172394334Sgshapiro Prevent small timeouts from being lost on slow machines if itimers 172494334Sgshapiro are used.

Based on 173294334Sgshapiro patch by Bryan Costales. 173394334Sgshapiro Initialize Timeout.iconnect in the code to prevent randomly short 173494334Sgshapiro timeouts. Problem noted by Bradley Watts of AT&T Canada. 173594334Sgshapiro Do not try to send a second SMTP QUIT command if the remote 173694334Sgshapiro responds to a MAIL command with a 421 reply or on I/O 173794334Sgshapiro errors. By doing so, the host was marked as having a 173894334Sgshapiro temporary problem and other mail destined for that host was 173994334Sgshapiro queued for the next queue run. Problem noted by Fletcher 174094334Sgshapiro Mattox of the University of Texas, Allan E Johannesen of 174194334Sgshapiro Worcester Polytechnic Institute, Larry Greenfield of CMU, 174294334Sgshapiro and Neil Rickert of Northern Illinois University. 174394334Sgshapiro Ignore error replies from the SMTP QUIT command (including servers 174494334Sgshapiro which drop the connection instead of responding to the 174594334Sgshapiro command). 174694334Sgshapiro Portability: 174794334Sgshapiro Check LDAP_API_VERSION to determine if ldap_memfree() is 174898121Sgshapiro available. 174994334Sgshapiro Define HPUX10 when building on HP-UX 10.X. That platform 175094334Sgshapiro now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR 175194334Sgshapiro settings. Patch from Elias Halldor Agustsson of 175294334Sgshapiro Skyrr. 175394334Sgshapiro Fix dependency building on Mac OS X and Darwin.

From 175794334Sgshapiro Rajesh Somasund of Hewlett-Packard. 175894334Sgshapiro CONFIG: Add FEATURE(`authinfo') to allow a separate database for 175994334Sgshapiro SMTP AUTH information. This feature was actually added in 176094334Sgshapiro 8.12.0 but a release note was not included. 176194334Sgshapiro CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce 176294334Sgshapiro parameter is set and the LDAP lookup returns a temporary 176394334Sgshapiro error. 176494334Sgshapiro CONFIG: Honor FEATURE(`relay_hosts_only') when using 176594334Sgshapiro FEATURE(`relay_mail_from', `domain'). Problem noted by 176694334Sgshapiro Krzysztof Oledzki. 176794334Sgshapiro CONFIG: FEATURE(`msp') now disables any type of alias 176894334Sgshapiro initialization as aliases are not needed for the MSP. 176994334Sgshapiro CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp') 177094334Sgshapiro is in use. Patch from Andrzej Filip. 177194334Sgshapiro CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of 177294334Sgshapiro `localhost' and turns on MX lookups for the SMTP mailers. 177394334Sgshapiro This will only have an effect if a parameter is specified, 177494334Sgshapiro i.e., an MX lookup will be performed on the hostname unless 177594334Sgshapiro it is embedded in square brackets. Problem noted by 177694334Sgshapiro Theo Van Dinter of Collective Technologies. 177794334Sgshapiro CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in 177894334Sgshapiro submit.cf) to use $TZ for time stamps. This is a compromise 177994334Sgshapiro to allow for the proper time zone on systems where the 178094334Sgshapiro default results in misleading time stamps. That is, syslog 178194334Sgshapiro time stamps and Date headers on submitted mail will use the 178294334Sgshapiro user's $TZ setting. Problem noted by Mark Roth of the 178394334Sgshapiro University of Illinois at Urbana-Champaign, solution proposed 178494334Sgshapiro by Neil Rickert of Northern Illinois University. 178594334Sgshapiro CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID 178694334Sgshapiro binary.

Problem noted 183090792Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 183190792Sgshapiro Properly record dropped connections in persistent host status. 183290792Sgshapiro Problem noted by Ulrich Windl of the Universitat 183390792Sgshapiro Regensburg. 183490792Sgshapiro Remove newlines from recipients read via sendmail -t to prevent 183590792Sgshapiro SMTP protocol errors when sending the RCPT command. 183690792Sgshapiro Problem noted by William D. Colburn of the New Mexico 183790792Sgshapiro Institute of Mining and Technology. 183890792Sgshapiro Only log milter body replacements once instead of for each body 183990792Sgshapiro chunk sent by a filter. Problem noted by Kari Hurtta of 184090792Sgshapiro the Finnish Meteorological Institute. 184190792Sgshapiro In 8.12.0 and 8.12.1, the headers were mistakenly not included in 184290792Sgshapiro the message size calculation. Problem noted by Kari Hurtta 184390792Sgshapiro of the Finnish Meteorological Institute. 184490792Sgshapiro Since 8.12 no longer forks at the SMTP MAIL command, the daemon 184590792Sgshapiro needs to collect children status to avoid zombie processes. 184690792Sgshapiro Problem noted by Chris Adams of HiWAAY Informations Services. 184790792Sgshapiro Shut down "nullserver" and ETRN-only connections after 25 bad 184890792Sgshapiro commands are issued. This makes it consistent with normal 184990792Sgshapiro SMTP connections. 185090792Sgshapiro Avoid duplicate logging of milter rejections. Problem noted by 185190792Sgshapiro William D. Colburn of the New Mexico Institute of Mining 185290792Sgshapiro and Technology. 185390792Sgshapiro Error and delay DSNs were being sent to postmaster instead of the 185490792Sgshapiro message sender if the sender had used a deprecated RFC822 185590792Sgshapiro source route. Problem noted by Kari Hurtta of the Finnish 185690792Sgshapiro Meteorological Institute. 185790792Sgshapiro Fix FallbackMXhost behavior for temporary errors during address 185890792Sgshapiro parsing.

Problem noted by Bjoern Voigt of TU Berlin. 188590792Sgshapiro Avoid a potential information leak if AUTH PLAIN is used and the 188690792Sgshapiro server gets stuck while processing that command. Problem 188790792Sgshapiro noted by Chris Adams from HiWAAY Informations Services. 188890792Sgshapiro In addition to printing errors when parsing recipients during 188990792Sgshapiro command line invocations log them to make it simpler 189090792Sgshapiro to understand possible DSNs to postmaster. 189190792Sgshapiro Do not use FallbackMXhost on mailers which have the F=0 flag set. 189290792Sgshapiro Allow local mailers (F=l) to specify a host for TCP connections 189390792Sgshapiro instead of forcing localhost. 189490792Sgshapiro Obey ${DESTDIR} for installation of the client mail queue and 189590792Sgshapiro submit.cf. Patch from Peter 'Luna' Runestig. 189690792Sgshapiro Re-enable support for -M option which was broken in 8.12.1. Problem 189790792Sgshapiro noted by Neil Rickert of Northern Illinois University. 189890792Sgshapiro If a remote server violates the SMTP standard by unexpectedly 189990792Sgshapiro dropping the connection during an SMTP transaction, stop 190090792Sgshapiro sending commands. This prevents bogus "Bad file number" 190190792Sgshapiro recipient status. Problem noted by Allan E Johannesen of 190290792Sgshapiro Worcester Polytechnic Institute. 190390792Sgshapiro Do not use a size estimate of 100 for postmaster bounces, it's 190490792Sgshapiro almost always too small; do not guess the size at all. 190590792Sgshapiro New VENDOR_DEC for Compaq/DEC. Requested by James Seagraves of 190690792Sgshapiro Compaq Computer Corp. 190790792Sgshapiro Fix DaemonPortOptions IPv6 address parsing such that ::1 works 190890792Sgshapiro properly.

Problem 198390792Sgshapiro found by Michal Zalewski. 198490792Sgshapiro PRIVACY: Prevent information leakage when sendmail has extra 198590792Sgshapiro privileges by disabling debugging (command line -d flag) 198690792Sgshapiro during queue runs and disabling ETRN when sendmail -bs is 198790792Sgshapiro used. Suggested by Michal Zalewski. 198890792Sgshapiro Avoid memory corruption problems resulting from bogus .cf files. 198990792Sgshapiro Problem found by Michal Zalewski. 199090792Sgshapiro Set the ${server_addr} macro to name of mailer when doing LMTP 199190792Sgshapiro delivery. LMTP systems may offer SMTP Authentication or 199290792Sgshapiro STARTTLS causing sendmail to use this macro in rulesets. 199390792Sgshapiro If debugging is turned on (-d0.10) print not just the default 199490792Sgshapiro values for configuration file and pid file but also the 199590792Sgshapiro selected values. Problem noted by Brad Chapman. 199690792Sgshapiro Continue dealing with broken nameservers by ignoring SERVFAIL 199790792Sgshapiro errors returned on T_AAAA (IPv6) lookups at delivery time 199890792Sgshapiro if ResolverOptions=WorkAroundBrokenAAAA is set. Previously 199990792Sgshapiro this only applied to hostname canonification. Problem 200090792Sgshapiro noted by Bill Fenner of AT&T Research. 200190792Sgshapiro Ignore comments in NIS host records when trying to find the 200290792Sgshapiro canonical name for a host. 200390792Sgshapiro When sendmail has extra privileges, limit mail submission command 200490792Sgshapiro line flags (i.e., -G, -h, -F, etc.) to mail submission 200590792Sgshapiro operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on 200690792Sgshapiro suggestion from Michal Zalewski. 200790792Sgshapiro Portability: 200890792Sgshapiro AIX: Use `oslevel` if available to determine OS version. 200990792Sgshapiro `uname` does not given complete information. 201090792Sgshapiro Problem noted by Keith Neufeld of the Cessna 201190792Sgshapiro Aircraft Company. 201290792Sgshapiro OpenUNIX: Use lockf() for LDA delivery (affects mail.local). 201390792Sgshapiro Problem noticed by Boyd Lynn Gerber of ZENEX. 201490792Sgshapiro Avoid compiler warnings by not using pointers to pass 201590792Sgshapiro integers.

You need to create a new user and 204890792Sgshapiro a new group before installing sendmail (both called smmsp by 204990792Sgshapiro default). The installation process tries to install 205090792Sgshapiro /etc/mail/submit.cf and creates /var/spool/clientmqueue by 205190792Sgshapiro default.

Suggested 206290792Sgshapiro by Michal Zalewski of the "Internet for Schools" project 206390792Sgshapiro (IdS). 206490792Sgshapiro Fixed problem of a global variable being used for a timeout jump 206590792Sgshapiro point where the variable could become overused for more than 206690792Sgshapiro one timeout concurrently. This erroneous behavior resulted in 206790792Sgshapiro a corrupted stack causing a core dump. The timeout is now 206890792Sgshapiro handled via libsm. Problem noted by Michael Shapiro, 206990792Sgshapiro John Beck, and Carl Smith of Sun Microsystems. 207090792Sgshapiro If sendmail is set-group-ID then that group ID is used for permission 207190792Sgshapiro checks (group ID of RunAsUser). This allows use of a 207290792Sgshapiro set-group-ID sendmail binary for initial message submission 207390792Sgshapiro and no set-user-ID root sendmail is needed. For details 207490792Sgshapiro see sendmail/SECURITY. 207590792Sgshapiro Log a warning if a non-trusted user changes the syslog label. 207690792Sgshapiro Based on notice from Bryan Costales of SL3D, Inc. 207790792Sgshapiro If sendmail is called for initial delivery, try to use submit.cf 207890792Sgshapiro with a fallback of sendmail.cf as configuration file. See 207990792Sgshapiro sendmail/SECURITY. 208090792Sgshapiro New configuration file option UseMSP to allow group writable queue 208190792Sgshapiro files if the group is the same as that of a set-group-ID 208290792Sgshapiro sendmail binary. See sendmail/SECURITY. 208390792Sgshapiro The .cf file is chosen based on the operation mode. For -bm (default), 208490792Sgshapiro -bs, and -t it is submit.cf if it exists for all others it 208590792Sgshapiro is sendmail.cf (to be backward compatible). This selection 208690792Sgshapiro can be changed by the new option -Ac or -Am (alternative .cf 208790792Sgshapiro file: client or mta). See sendmail/SECURITY. 208890792Sgshapiro The SMTP server no longer forks on each MAIL command. The ONEX 208990792Sgshapiro command has been removed. 209090792Sgshapiro Implement SMTP PIPELINING per RFC 2920. It can be turned off 209190792Sgshapiro at compile time or per host (ruleset). 209290792Sgshapiro New option MailboxDatabase specifies the type of mailbox database 209390792Sgshapiro used to look up local mail recipients; the default value 209490792Sgshapiro is "pw", which means to use getpwnam(). New mailbox database 209590792Sgshapiro types can be added by adding custom code to libsm/mbdb.c. 209690792Sgshapiro Queue file names are now 15 characters long, rather than 14 characters 209790792Sgshapiro long, to accomodate envelope splitting. File systems with 209890792Sgshapiro a 14 character file name length limit are no longer 209990792Sgshapiro supported. 210090792Sgshapiro Recipient list used for delivery now gets internally ordered by 210190792Sgshapiro hostsignature (character string version of MX RR). This orders 210290792Sgshapiro recipients for the same MX RR's together meaning smaller 210390792Sgshapiro portions of the list need to be scanned (instead of the whole 210490792Sgshapiro list) each delivery() pass to determine piggybacking. The 210590792Sgshapiro significance of the change is better the larger the recipient 210690792Sgshapiro list. Hostsignature is now created during recipient list 210790792Sgshapiro creation rather than just before delivery. 210890792Sgshapiro Enhancements for more opportunistic piggybacking. Previous 210990792Sgshapiro piggybacking (called coincidental) extended to coattail 211090792Sgshapiro piggybacking. Rather than complete MX RR matching 211190792Sgshapiro (coincidental) piggybacking is done if just the lowest value 211290792Sgshapiro preference matches (coattail). 211390792Sgshapiro If sendmail receives a temporary error on a RCPT TO: command, it will 211490792Sgshapiro try other MX hosts if available. 211590792Sgshapiro DefaultAuthInfo can contain a list of mechanisms to be used for 211690792Sgshapiro outgoing (client-side) SMTP Authentication. 211790792Sgshapiro New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable 211890792Sgshapiro AUTH (overrides 'a' modifier in DaemonPortOptions). Based 211990792Sgshapiro on patch from Lyndon Nerenberg of Messaging Direct. 212090792Sgshapiro Enable AUTH mechanism EXTERNAL if STARTTLS is used. 212190792Sgshapiro A new ruleset authinfo can be used to return client side 212290792Sgshapiro authentication information for AUTH instead of DefaultAuthInfo. 212390792Sgshapiro Therefore the DefaultAuthInfo option is deprecated and will be 212490792Sgshapiro removed in future versions. 212590792Sgshapiro Accept any SMTP continuation code 3xy for AUTH even though RFC 2554 212690792Sgshapiro requires 334. Mercury 1.48 is a known offender. 212790792Sgshapiro Add new option AuthMaxBits to limit the overall encryption strength 212890792Sgshapiro for the security layer in SMTP AUTH (SASL). See 212990792Sgshapiro doc/op/op.me for details. 213090792Sgshapiro Introduce new STARTTLS related macros {cn_issuer}, {cn_subject}, 213190792Sgshapiro {cert_md5} which hold the CN (common name) of the CA that 213290792Sgshapiro signed the presented certificate, the CN and the MD5 hash 213390792Sgshapiro of the presented certificate, respectively. 213490792Sgshapiro New ruleset try_tls to decide whether to try (as client) STARTTLS. 213590792Sgshapiro New ruleset srv_features to enable/disable certain features in the 213690792Sgshapiro server per connection. See doc/op/op.me for details. 213790792Sgshapiro New ruleset tls_rcpt to decide whether to send e-mail to a particular 213890792Sgshapiro recipient; useful to decide whether a conection is secure 213990792Sgshapiro enough on a per recipient basis. 214090792Sgshapiro New option TLSSrvOptions to modify some aspects of the server 214190792Sgshapiro for STARTTLS. 214290792Sgshapiro If no certificate has been requested, the macro {verify} has the 214390792Sgshapiro value "NOT". 214490792Sgshapiro New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off 214590792Sgshapiro using/offering STARTTLS when delivering/receiving e-mail. 214690792Sgshapiro Macro expand filenames/directories for certs and keys in the .cf file. 214790792Sgshapiro Proposed by Neil Rickert of Northern Illinois University. 214890792Sgshapiro Generate an ephemeral RSA key for a STARTTLS connection only if 214990792Sgshapiro really required. This change results in a noticable 215090792Sgshapiro performance gains on most machines. Moreover, if shared 215190792Sgshapiro memory is in use, reuse the key several times. 215290792Sgshapiro Add queue groups which can be used to group queue directories with 215390792Sgshapiro the same behavior together. See doc/op/op.me for details. 215490792Sgshapiro If the new option FastSplit (defaults to one) has a value greater 215590792Sgshapiro than zero, it suppresses the MX lookups on addresses when they 215690792Sgshapiro are initially sorted which may result in faster envelope 215790792Sgshapiro splitting. If the mail is submitted directly from the 215890792Sgshapiro command line, then the value also limits the number of 215990792Sgshapiro processes to deliver the envelopes; if more envelopes are 216090792Sgshapiro created they are only queued up and must be taken care of 216190792Sgshapiro by a queue run. 216290792Sgshapiro The check for 'enough disk space' now pays attention to which file 216390792Sgshapiro system each queue directory resides in. 216490792Sgshapiro All queue runners can be cleanly terminated via SIGTERM to parent. 216590792Sgshapiro New option QueueFileMode for the default permissions of queue files. 216690792Sgshapiro Add parallel queue runner code. Allows multiple queue runners per work 216790792Sgshapiro group (one or more queues in a multi-queue environment 216890792Sgshapiro collected together) to process the same work list at the 216990792Sgshapiro same time. 217090792Sgshapiro Option MaxQueueChildren added to limit the number of concurrently 217190792Sgshapiro active queue runner processes. 217290792Sgshapiro New option MaxRunnersPerQueue to specify the maximum number of queue 217390792Sgshapiro runners per queue group. 217490792Sgshapiro Queue member selection by substring pattern matching now allows 217590792Sgshapiro the pattern to be negated. For -qI, -qR and -qS it is 217690792Sgshapiro permissible for -q!I, -q!R and -q!S to mean remove members 217790792Sgshapiro of the queue that match during processing. 217890792Sgshapiro New -qp[time] option is similar to -qtime, except that instead of 217990792Sgshapiro periodically forking a child to process the queue, a single 218090792Sgshapiro child is forked for each queue that sleeps between queue 218190792Sgshapiro runs. A SIGHUP signal can be sent to restart this 218290792Sgshapiro persistent queue runner. 218390792Sgshapiro The SIGHUP signal now restarts a timed queue run process (i.e., a 218490792Sgshapiro sendmail process which only runs the queue at an interval: 218590792Sgshapiro sendmail -q15m). 218690792Sgshapiro New option NiceQueueRun to set the priority of queue runners. 218790792Sgshapiro Proposed by Thom O'Connor. 218890792Sgshapiro sendmail will run the queue(s) in the background when invoked with -q 218990792Sgshapiro unless the new -qf option or -v is used. 219090792Sgshapiro QueueSortOrder=Random sorts the queue randomly, which is useful if 219190792Sgshapiro several queue runners are started by hand to avoid contention. 219290792Sgshapiro QueueSortOrder=Modification sorts the queue by the modification time 219390792Sgshapiro of the qf file (older entries first). 219490792Sgshapiro Support Deliver By SMTP Service Extension (RFC 2852) which allows 219590792Sgshapiro a client to specify an amount of time within which an e-mail 219690792Sgshapiro should be delivered. New option DeliverByMin added to set the 219790792Sgshapiro minimum amount of time or disable the extension. 219890792Sgshapiro Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are 219990792Sgshapiro not allowed unless escaped or quoted. 220090792Sgshapiro Add support for a generic DNS map. Based on a patch contributed 220190792Sgshapiro by Leif Johansson of Stockholm University, which was based on 220290792Sgshapiro work by Assar Westerlund of Swedish Institute of Computer 220390792Sgshapiro Science, Kista, and Johan Danielsson of Royal Institute of 220490792Sgshapiro Technology, Stockholm, Sweden. 220590792Sgshapiro MX records will be looked up for FallBackMXhost. To use the old 220690792Sgshapiro behavior (no MX lookups), put the name in square brackets. 220790792Sgshapiro Proposed by Thom O'Connor. 220890792Sgshapiro Use shared memory to store free space of filesystems that are used 220990792Sgshapiro for queues, if shared memory is available and if a key is set 221090792Sgshapiro via SharedMemoryKey. This minimizes the number of system 221190792Sgshapiro calls to check the available space. See doc/op/op.me for 221290792Sgshapiro details. 221390792Sgshapiro If shared memory is compiled in the option -bP can be used to print 221490792Sgshapiro the number of entries in the queue(s). 221590792Sgshapiro Enable generic mail filter API (milter). See libmilter/README 221690792Sgshapiro and the usual documentation for details. 221790792Sgshapiro Remove AutoRebuildAliases option, deprecated since 8.10. 221890792Sgshapiro Remove '-U' (initial user submission) command line option as 221990792Sgshapiro announced in 8.10. 222090792Sgshapiro Remove support for non-standard SMTP command XUSR. Use an MSA instead. 222190792Sgshapiro New macro {addr_type} which contains whether the current address is 222290792Sgshapiro an envelope sender or recipient address. Suggested by 222390792Sgshapiro Neil Rickert of Northern Illinois University. 222490792Sgshapiro Two new options for host maps: -d (retransmission timeout), 222590792Sgshapiro -r (number of retries). 222690792Sgshapiro New option for LDAP maps: the -V<sep> allows you to specify a 222790792Sgshapiro separator such that a lookup can return both an attribute 222890792Sgshapiro and value separated by the given separator. 222990792Sgshapiro Add new operators '%', '|', '&' (modulo, binary or, binary and) 223090792Sgshapiro to map class arith. 223190792Sgshapiro If DoubleBounceAddress expands to an empty string, ``double bounces'' 223290792Sgshapiro (errors that occur when sending an error message) are dropped. 223390792Sgshapiro New DontBlameSendmail options GroupReadableSASLDBFile and 223490792Sgshapiro GroupWritableSASLDBFile to relax requirements for sasldb files. 223590792Sgshapiro New DontBlameSendmail options GroupReadableKeyFile to relax 223690792Sgshapiro requirements for files containing secret keys. This is 223790792Sgshapiro necessary for the MSP if client authentification is used. 223890792Sgshapiro Properly handle quoted filenames for class files (to allow for 223990792Sgshapiro filenames with spaces). 224090792Sgshapiro Honor the resolver option RES_NOALIASES when canonifying hostnames. 224190792Sgshapiro Add macros to avoid the reuse of {if_addr} etc: 224290792Sgshapiro {if_name_out} hostname of interface of outgoing connection. 224390792Sgshapiro {if_addr_out} address of interface of outgoing connection. 224490792Sgshapiro {if_family_out} family of interface of outgoing connection. 224590792Sgshapiro The latter two are only set if the interface does not belong 224690792Sgshapiro to the loopback net. 224790792Sgshapiro Add macro {nrcpts} which holds the number of (validated) recipients. 224890792Sgshapiro DialDelay option applies only to mailers with flag 'Z'. Patch from 224990792Sgshapiro Juergen Georgi of RUS University of Stuttgart. 225090792Sgshapiro New Timeout.lhlo,auth,starttls options to limit the time waiting for 225190792Sgshapiro an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command. 225290792Sgshapiro New Timeout.aconnect option to limit the overall waiting time for 225390792Sgshapiro all connections for a single delivery attempt to succeed. 225490792Sgshapiro Limit the rate recipients in the SMTP envelope are accepted once 225590792Sgshapiro a threshold number of recipients has been rejected (option 225690792Sgshapiro BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD 225790792Sgshapiro Development Group. 225890792Sgshapiro New option DelayLA to delay connections if the load averages 225990792Sgshapiro exceeds the specified value. The default of 0 does not 226090792Sgshapiro change the previous behavior. A value greater than 0 226190792Sgshapiro will cause sendmail to sleep for one second on most 226290792Sgshapiro SMTP commands and before accepting connections if that 226390792Sgshapiro load average is exceeded. 226490792Sgshapiro Use a dynamic (instead of fixed-size) buffer for the list of 226590792Sgshapiro recipients that are sent during a connection to a mailer. 226690792Sgshapiro This also introduces a new mailer field 'r' which defines 226790792Sgshapiro the maximum number of recipients (defaults to 100). 226890792Sgshapiro Based on patch by Motonori Nakamura of Kyoto University. 226990792Sgshapiro Add new F=1 mailer flag to disable sending of null characters ('\0'). 227090792Sgshapiro Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead. 227190792Sgshapiro The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC] 227290792Sgshapiro instead. 227390792Sgshapiro IPC is no longer available as first mailer argument (A=) for [IPC] 227490792Sgshapiro builtin mailer pathnames. Use TCP instead. 227590792Sgshapiro PH map code updated to use the new libphclient API instead of the 227690792Sgshapiro old libqiapi library. Contributed by Mark Roth of the 227790792Sgshapiro University of Illinois at Urbana-Champaign. 227890792Sgshapiro New option DirectSubmissionModifiers to define {daemon_flags} 227990792Sgshapiro for direct (command line) submissions. 228090792Sgshapiro New M=O modifier for DaemonPortOptions to ignore the socket in 228190792Sgshapiro case of failures. Based on patch by Jun-ichiro itojun 228290792Sgshapiro Hagino of the KAME Project. 228390792Sgshapiro Add Disposition-Notification-To: (RFC 2298) to the list of headers 228490792Sgshapiro whose content is rewritten similar to Reply-To:. 228590792Sgshapiro Proposed by Andrzej Filip. 228690792Sgshapiro Use STARTTLS/AUTH=server/client for logging incoming/outgoing 228790792Sgshapiro STARTTLS/AUTH connections; log incoming connections at level 228890792Sgshapiro 9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP 228990792Sgshapiro AUTH/STARTTLS related logfile entries. 229090792Sgshapiro Convert unprintable characters (and backslash) into octal or C format 229190792Sgshapiro before logging. 229290792Sgshapiro Log recipients if no message is transferred but QUIT/RSET is given 229390792Sgshapiro (at LogLevel 9/10 or higher). 229490792Sgshapiro Log discarded recipients at LogLevel 10 or higher. 229590792Sgshapiro Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections 229690792Sgshapiro in which most commands are rejected due to check_relay or 229790792Sgshapiro TCP Wrappers if the host tries one of those commands anyway. 229890792Sgshapiro Change logging format for cloned envelopes to be similar to that for 229990792Sgshapiro DSNs ("old id: new id: clone"). Suggested by Ulrich Windl 230090792Sgshapiro of the Universitat Regensburg. 230190792Sgshapiro Added libsm, a C library of general purpose abstractions including 230290792Sgshapiro assertions, tracing and debugging with named debug categories, 230390792Sgshapiro exception handling, malloc debugging, resource pools, 230490792Sgshapiro portability abstractions, and an extensible buffered I/O 230590792Sgshapiro package. It will at some point replace libsmutil. 230690792Sgshapiro See libsm/index.html for details. 230790792Sgshapiro Fixed most memory leaks in sendmail which were previously taken 230890792Sgshapiro care of by fork() and exit(). 230990792Sgshapiro Use new sm_io*() functions in place of stdio calls. Allows for 231090792Sgshapiro more consistent portablity amongst different platforms 231190792Sgshapiro new and old (from new libsm). 231290792Sgshapiro Common I/O pkg means just one buffering method needed instead of two 231390792Sgshapiro ('bf_portable' and 'bf_torek' now just 'bf'). 231490792Sgshapiro Sfio no longer needed as SASL/TLS code uses sm_io*() API's. 231590792Sgshapiro New possible value 'interactive' for SuperSafe which can be used 231690792Sgshapiro together with DeliveryMode=interactive is to avoid some disk 231790792Sgshapiro synchronizations calls. 231890792Sgshapiro Add per-recipient status information to mailq -v output. 231990792Sgshapiro T_ANY queries are no longer used by sendmail. 232090792Sgshapiro When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS" 232190792Sgshapiro too (see include/sm/cdefs.h for more info). 232290792Sgshapiro sendmail -d now has general support for named debug categories. 232390792Sgshapiro See libsm/debug.html and section 3.4 of doc/op/op.me 232490792Sgshapiro for details. 232590792Sgshapiro Eliminate the "postmaster warning" DSNs on address parsing errors 232690792Sgshapiro such as unbalanced angle brackets or parentheses. The DSNs 232790792Sgshapiro generated by this condition were illegal (not RFC conform). 232890792Sgshapiro Problem noted by Ulrich Windl of the Universitaet Regensburg. 232990792Sgshapiro Do not issue a DSN if the ruleset localaddr resolves to the $#error 233090792Sgshapiro mailer and the recipient has hence been rejected during the 233190792Sgshapiro SMTP dialogue. Problem reported by Larry Greenfield of CMU. 233290792Sgshapiro Deal with a case of multiple deliveries on misconfigured systems 233390792Sgshapiro that do not have postmaster defined. If an email was sent 233490792Sgshapiro from an address to which a DSN cannot be returned and 233590792Sgshapiro in which at least one recipient address is non-deliverable, 233690792Sgshapiro then that email had been delivered in each queue run. 233790792Sgshapiro Problem reported by Matteo HCE Valsasna of Universita 233890792Sgshapiro degli Studi dell'Insubria. 233990792Sgshapiro The compilation options SMTP, DAEMON, and QUEUE have been removed, 234090792Sgshapiro i.e., the corresponding code is always compiled in now. 234190792Sgshapiro Log the command line in daemon/queue-run mode at LogLevel 10 and 234290792Sgshapiro higher. Suggested by Robert Harker of Harker Systems. 234390792Sgshapiro New ResolverOptions setting: WorkAroundBrokenAAAA. When 234490792Sgshapiro attempting to canonify a hostname, some broken nameservers 234590792Sgshapiro will return SERVFAIL (a temporary failure) on T_AAAA (IPv6) 234690792Sgshapiro lookups. If you want to excuse this behavior, use this new 234790792Sgshapiro flag. Suggested by Chris Foote of SE Network Access and 234890792Sgshapiro Mark Roth of the University of Illinois at 234990792Sgshapiro Urbana-Champaign. 235090792Sgshapiro Free the memory allocated by getipnodeby{addr,name}(). Problem 235190792Sgshapiro noted by Joy Latten of IBM. 235290792Sgshapiro ConnectionRateThrottle limits the number of connections per second 235390792Sgshapiro to each daemon individually, not the overall number of 235490792Sgshapiro connections. 235590792Sgshapiro Specifying only "ldap:" as an AliasFile specification will force 235690792Sgshapiro sendmail to use a default alias schema as outlined in the 235790792Sgshapiro ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of 235890792Sgshapiro cf/README. 235990792Sgshapiro Add a new syntax for the 'F' (file class) sendmail.cf command. If 236090792Sgshapiro the first character after the class name is not a '/' or a 236190792Sgshapiro '|' and it contains an '@' (e.g., F{X}key@class:spec), the 236290792Sgshapiro rest of the line will be parsed as a map lookup. This 236390792Sgshapiro allows classes to be filled via a map lookup. See op.me 236490792Sgshapiro for more syntax information. Specifically, this can be 236590792Sgshapiro used for commands such as VIRTUSER_DOMAIN_FILE() to read 236690792Sgshapiro the list of domains via LDAP (see the ``USING LDAP FOR 236790792Sgshapiro ALIASES, MAPS, and CLASSES'' section of cf/README for an 236890792Sgshapiro example). 236990792Sgshapiro The new macro ${sendmailMTACluster} determines the LDAP cluster for 237090792Sgshapiro the default schema used in the above two items. 237190792Sgshapiro Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a 237290792Sgshapiro warning if a program being run from a mailer or file class 237390792Sgshapiro (e.g., F|/path/to/prog) is in an unsafe directory path. 237490792Sgshapiro Unless DontBlameSendmail=RunWritableProgram is set, log a warning 237590792Sgshapiro if a program being run from a mailer or file class 237690792Sgshapiro (e.g., F|/path/to/prog) is group or world writable. 237790792Sgshapiro Loopback interfaces (e.g., "lo0") are now probed for class {w} 237890792Sgshapiro hostnames. Setting DontProbeInterfaces to "loopback" 237990792Sgshapiro (without quotes) will disable this and return to the 238090792Sgshapiro pre-8.12 behavior of only probing non-loopback interfaces. 238190792Sgshapiro Suggested by Bryan Stansell of GNAC. 238290792Sgshapiro In accordance with RFC 2821 section 4.1.4, accept multiple 238390792Sgshapiro HELO/EHLO commands. 238490792Sgshapiro Multiple ClientPortOptions settings are now allowed, one for each 238590792Sgshapiro possible protocol family which may be used for outgoing 238690792Sgshapiro connections. Restrictions placed on one family only affect 238790792Sgshapiro outgoing connections on that particular family. Because of 238890792Sgshapiro this change, the ${client_flags} macro is not set until the 238990792Sgshapiro connection is established. Based on patch from Motonori 239090792Sgshapiro Nakamura of Kyoto University. 239190792Sgshapiro PrivacyOptions=restrictexpand instructs sendmail to drop privileges 239290792Sgshapiro when the -bv option is given by users who are neither root 239390792Sgshapiro nor the TrustedUser so users can not read private aliases, 239490792Sgshapiro forwards, or :include: files. It also will override the -v 239590792Sgshapiro (verbose) command line option. 239690792Sgshapiro If the M=b modifier is set in DaemonPortOptions and the interface 239790792Sgshapiro address can't be used for the outgoing connection, fall 239890792Sgshapiro back to the settings in ClientPortOptions (if set). 239990792Sgshapiro Problem noted by John Beck of Sun Microsystems. 240090792Sgshapiro New named config file rule check_data for DATA command (input: 240190792Sgshapiro number of recipients). Based on patch from Mark Roth of 240290792Sgshapiro the University of Illinois at Urbana-Champaign. 240390792Sgshapiro Add support for ETRN queue selection per RFC 1985. The queue group 240490792Sgshapiro can be specified using the '#' option character. For 240590792Sgshapiro example, 'ETRN #queuegroup'. 240690792Sgshapiro If an LDAP server times out or becomes unavailable, close the 240790792Sgshapiro current connection and reopen to get to one of the fallback 240890792Sgshapiro servers. Patch from Paul Hilchey of the University of 240990792Sgshapiro British Columbia. 241090792Sgshapiro Make default error number on $#error messages 550 instead of 501 241190792Sgshapiro because 501 is not allowed on all commands. 241290792Sgshapiro The .cf file option UnsafeGroupWrites is deprecated, it should be 241390792Sgshapiro replaced with the settings GroupWritableForwardFileSafe 241490792Sgshapiro and GroupWritableIncludeFileSafe in DontBlameSendmail 241590792Sgshapiro if required. 241690792Sgshapiro The deprecated ldapx map class has been removed. Use the ldap map 241790792Sgshapiro class instead. 241890792Sgshapiro Any IPv6 addresses used in configuration should be prefixed by the 241990792Sgshapiro "IPv6:" tag to identify the address properly. For example, 242090792Sgshapiro if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to 242190792Sgshapiro class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4]. 242290792Sgshapiro Change the $&{opMode} macro if the operation mode changes while the 242390792Sgshapiro MTA is running. For example, during a queue run. 242490792Sgshapiro Add "use_inet6" as a new ResolverOptions flag to control the 242590792Sgshapiro RES_USE_INET6 resolver option.

Problem 321964562Sgshapiro noted by Slawomir Piotrowski of TELSAT GP. 322064562Sgshapiro Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS). 322164562Sgshapiro Implementation influenced by the example programs of 322264562Sgshapiro OpenSSL and the work of Lutz Jaenicke of TU Cottbus. 322364562Sgshapiro Add new STARTTLS related options CACERTPath, CACERTFile, 322464562Sgshapiro ClientCertFile, ClientKeyFile, DHParameters, RandFile, 322564562Sgshapiro ServerCertFile, and ServerKeyFile. These are documented in 322664562Sgshapiro cf/README and doc/op/op.*. 322764562Sgshapiro New STARTTLS related macros: ${cert_issuer}, ${cert_subject}, 322864562Sgshapiro ${tls_version}, ${cipher}, ${cipher_bits}, ${verify}, 322964562Sgshapiro ${server_name}, and ${server_addr}. These are documented 323064562Sgshapiro in cf/README and doc/op/op.*. 323164562Sgshapiro Add support for the Entropy Gathering Daemon (EGD) for better 323264562Sgshapiro random data. 323364562Sgshapiro New DontBlameSendmail option InsufficientEntropy for systems which 323464562Sgshapiro don't properly seed the PRNG for OpenSSL but want to 323564562Sgshapiro try to use STARTTLS despite the security problems. 323664562Sgshapiro Support the security layer in SMTP AUTH for mechanisms which 323764562Sgshapiro support encryption. Based on code contributed by Tim 323864562Sgshapiro Martin of CMU. 323964562Sgshapiro Add new macro ${auth_ssf} to reflect the SMTP AUTH security 324064562Sgshapiro strength factor. 324164562Sgshapiro LDAP's -1 (single match only) flag was not honored if the -z 324264562Sgshapiro (delimiter) flag was not given. Problem noted by ST Wong of 324364562Sgshapiro the Chinese University of Hong Kong. Fix from Mark Adamson 324464562Sgshapiro of CMU. 324564562Sgshapiro Add more protection from accidentally tripping OpenLDAP 1.X's 324664562Sgshapiro ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute(). 324764562Sgshapiro Suggested by Kurt Zeilenga of OpenLDAP. 324864562Sgshapiro Fix the default family selection for DaemonPortOptions. As 324964562Sgshapiro documented, unless a family is specified in a 325064562Sgshapiro DaemonPortOptions option, "inet" is the default. It is 325164562Sgshapiro also the default if no DaemonPortOptions value is set. 325264562Sgshapiro Therefore, IPv6 users should configure additional sockets 325364562Sgshapiro by adding DaemonPortOptions settings with Family=inet6 if 325464562Sgshapiro they wish to also listen on IPv6 interfaces. Problem noted 325564562Sgshapiro by Jun-ichiro itojun Hagino of the KAME Project. 325664562Sgshapiro Set ${if_family} when setting ${if_addr} and ${if_name} to reflect 325764562Sgshapiro the interface information for an outgoing connection. 325864562Sgshapiro Not doing so was creating a mismatch between the socket 325964562Sgshapiro family and address used in subsequent connections if the 326064562Sgshapiro M=b modifier was set in DaemonPortOptions. Problem noted 326164562Sgshapiro by John Beck of Sun Microsystems. 326264562Sgshapiro If DaemonPortOptions modifier M=b is used, determine the socket 326364562Sgshapiro family based on the IP address. ${if_family} is no longer 326464562Sgshapiro persistent (i.e., saved in qf files). Patch from John Beck 326564562Sgshapiro of Sun Microsystems. 326664562Sgshapiro sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family} 326764562Sgshapiro macros for both the incoming interface address/family and 326864562Sgshapiro the outgoing interface address/family. In order for M=b 326964562Sgshapiro modifier in DaemonPortOptions to work properly, preserve 327064562Sgshapiro the incoming information in the queue file for later 327164562Sgshapiro delivery attempts. 327264562Sgshapiro Use SMTP error code and enhanced status code from check_relay in 327364562Sgshapiro responses to commands.

Contributed by Exactis.com, Inc. 360564562Sgshapiro New option DataFileBufferSize to control the maximum size of a 360664562Sgshapiro memory-buffered data (df) file before a disk-based file is 360764562Sgshapiro used. Contributed by Exactis.com, Inc. 360864562Sgshapiro New option XscriptFileBufferSize to control the maximum size of a 360964562Sgshapiro memory-buffered transcript (xf) file before a disk-based 361064562Sgshapiro file is used. Contributed by Exactis.com, Inc. 361164562Sgshapiro sendmail implements RFC 2476 (Message Submission), e.g., it can 361264562Sgshapiro now listen on several different ports. Use: 361364562Sgshapiro O DaemonPortOptions=Name=MSA, Port=587, M=E 361464562Sgshapiro to run a Message Submission Agent (MSA); this is turned 361564562Sgshapiro on by default in m4-generated .cf files; it can be turned 361664562Sgshapiro off with FEATURE(`no_default_msa'). 361764562Sgshapiro The 'XUSR' SMTP command is deprecated. Mail user agents should 361864562Sgshapiro begin using RFC 2476 Message Submission for initial user 361964562Sgshapiro message submission. XUSR may disappear from a future release. 362064562Sgshapiro The new '-G' (relay (gateway) submission) command line option 362164562Sgshapiro indicates that the message being submitted from the command 362264562Sgshapiro line is for relaying, not initial submission. This means 362364562Sgshapiro the message will be rejected if the addresses are not fully 362464562Sgshapiro qualified and no canonicalization will be done. Future 362564562Sgshapiro releases may even reject improperly formed messages. 362664562Sgshapiro The '-U' (initial user submission) command line option is 362764562Sgshapiro deprecated and may be removed from a future release. 362864562Sgshapiro Mail user agents should begin using '-G' to indicate that 362964562Sgshapiro this is a relay submission (the inverse of -U). 363064562Sgshapiro The next release of sendmail will assume that any message submitted 363164562Sgshapiro from the command line is an initial user submission and act 363264562Sgshapiro accordingly. 363364562Sgshapiro If sendmail doesn't have enough privileges to run a .forward 363464562Sgshapiro program or deliver to file as the owner of that file, the 363564562Sgshapiro address is marked as unsafe. This means if RunAsUser is 363664562Sgshapiro set, users won't be able to use programs or delivery to 363764562Sgshapiro files in their .forward files. Administrators can override 363864562Sgshapiro this by setting the DontBlameSendmail option to the new 363964562Sgshapiro setting NonRootSafeAddr. 364064562Sgshapiro Allow group or world writable directories if the sticky bit is set 364164562Sgshapiro on the directory and DontBlameSendmail is set to 364264562Sgshapiro TrustStickyBit. Based on patch from Chris Metcalf of 364364562Sgshapiro InCert Software. 364464562Sgshapiro Prevent logging of unsafe directory paths for non-existent forward 364564562Sgshapiro files if the new DontWarnForwardFileInUnsafeDirPath bit is 364664562Sgshapiro set in the DontBlameSendmail option. Requested by many. 364764562Sgshapiro New Timeout.control option to limit the total time spent satisfying 364864562Sgshapiro a control socket request. 364964562Sgshapiro New Timeout.resolver options for controlling BIND resolver 365064562Sgshapiro settings: 365164562Sgshapiro Timeout.resolver.retrans 365264562Sgshapiro Sets the resolver's retransmission time interval (in 365364562Sgshapiro seconds). Sets both Timeout.resolver.retrans.first 365464562Sgshapiro and Timeout.resolver.retrans.normal. 365564562Sgshapiro Timeout.resolver.retrans.first 365664562Sgshapiro Sets the resolver's retransmission time interval (in 365764562Sgshapiro seconds) for the first attempt to deliver a message. 365864562Sgshapiro Timeout.resolver.retrans.normal 365964562Sgshapiro Sets the resolver's retransmission time interval (in 366064562Sgshapiro seconds) for all resolver lookups except the first 366164562Sgshapiro delivery attempt. 366264562Sgshapiro Timeout.resolver.retry 366364562Sgshapiro Sets the number of times to retransmit a resolver 366464562Sgshapiro query. Sets both Timeout.resolver.retry.first 366564562Sgshapiro and Timeout.resolver.retry.normal. 366664562Sgshapiro Timeout.resolver.retry.first 366764562Sgshapiro Sets the number of times to retransmit a resolver 366864562Sgshapiro query for the first attempt to deliver a message. 366964562Sgshapiro Timeout.resolver.retry.normal 367064562Sgshapiro Sets the number of times to retransmit a resolver 367164562Sgshapiro query for all resolver lookups except the first 367264562Sgshapiro delivery attempt. 367364562Sgshapiro Contributed by Exactis.com, Inc. 367464562Sgshapiro Support multiple queue directories. To use multiple queues, supply 367564562Sgshapiro a QueueDirectory option value ending with an asterisk. For 367664562Sgshapiro example, /var/spool/mqueue/q* will use all of the 367764562Sgshapiro directories or symbolic links to directories beginning with 367864562Sgshapiro 'q' in /var/spool/mqueue as queue directories. Keep in 367964562Sgshapiro mind, the queue directory structure should not be changed 368064562Sgshapiro while sendmail is running. Queue runs create a separate 368164562Sgshapiro process for running each queue unless the verbose flag is 368264562Sgshapiro given on a non-daemon queue run. New items are randomly 368364562Sgshapiro assigned to a queue. Contributed by Exactis.com, Inc. 368464562Sgshapiro Support different directories for qf, df, and xf queue files; if 368564562Sgshapiro subdirectories or symbolic links to directories of those names 368664562Sgshapiro exist in the queue directories, they are used for the 368764562Sgshapiro corresponding queue files. Keep in mind, the queue 368864562Sgshapiro directory structure should not be changed while sendmail is 368964562Sgshapiro running. Proposed by Mathias Koerber of Singapore 369064562Sgshapiro Telecommunications Ltd. 369164562Sgshapiro New queue file naming system which uses a filename guaranteed to be 369264562Sgshapiro unique for 60 years. This allows queue IDs to be assigned 369364562Sgshapiro without fancy file system locking. Queued items can be 369464562Sgshapiro moved between queues easily. Contributed by Exactis.com, 369564562Sgshapiro Inc. 369664562Sgshapiro Messages which are undeliverable due to temporary address failures 369764562Sgshapiro (e.g., DNS failure) will now go to the FallBackMX host, if 369864562Sgshapiro set. Contributed by Exactis.com, Inc. 369964562Sgshapiro New command line option '-L tag' which sets the identifier used for 370064562Sgshapiro syslog. Contributed by Exactis.com, Inc. 370164562Sgshapiro QueueSortOrder=Filename will sort the queue by filename. This 370264562Sgshapiro avoids opening and reading each queue file when preparing 370364562Sgshapiro to run the queue. Contributed by Exactis.com, Inc. 370464562Sgshapiro Shared memory counters and microtimers functionality has been 370564562Sgshapiro donated by Exactis.com, Inc. 370664562Sgshapiro The SCCS ID tags have been replaced with RCS ID tags. 370764562Sgshapiro Allow trusted users (those on a T line or in $=t) to set the 370864562Sgshapiro QueueDirectory (Q) option without an X-Authentication-Warning: 370964562Sgshapiro being added. Suggested by Michael K. Sanders. 371064562Sgshapiro IPv6 support based on patches from John Kennedy of Cal State 371164562Sgshapiro University, Chico, Motonori Nakamura of Kyoto University, 371264562Sgshapiro and John Beck of Sun Microsystems. 371364562Sgshapiro In low-disk space situations, where sendmail would previously refuse 371464562Sgshapiro connections, still accept them, but only allow ETRN commands. 371564562Sgshapiro Suggested by Mathias Koerber of Singapore Telecommunications 371664562Sgshapiro Ltd. 371764562Sgshapiro The [IPC] builtin mailer now allows delivery to a UNIX domain socket 371864562Sgshapiro on systems which support them. This can be used with LMTP 371964562Sgshapiro local delivery agents which listen on a named socket. An 372064562Sgshapiro example mailer might be: 372164562Sgshapiro Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n, 372264562Sgshapiro S=10, R=20/40, T=DNS/RFC822/X-Unix, 372364562Sgshapiro A=FILE /var/run/lmtpd 372464562Sgshapiro Code contributed by Lyndon Nerenberg of Messaging Direct. 372564562Sgshapiro The [TCP] builtin mailer name is now deprecated. Use [IPC] 372664562Sgshapiro instead. 372764562Sgshapiro The first mailer argument in the [IPC] mailer is now checked for a 372864562Sgshapiro legitimate value. Possible values are TCP (for TCP/IP 372964562Sgshapiro connections), IPC (which will be deprecated in a future 373064562Sgshapiro version), and FILE (for UNIX domain socket delivery). 373164562Sgshapiro PrivacyOptions=goaway no longer includes the noetrn and the noreceipts 373264562Sgshapiro flags. 373364562Sgshapiro PrivacyOptions=nobodyreturn instructs sendmail not to include the 373464562Sgshapiro body of the original message on delivery status 373564562Sgshapiro notifications. 373664562Sgshapiro Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted 373764562Sgshapiro by Dan Bernstein, fix from Robert Harker of Harker Systems. 373864562Sgshapiro Accept the SMTP RSET command even when rejecting commands due to TCP 373964562Sgshapiro Wrappers or the check_relay ruleset. Problem noted by 374064562Sgshapiro Steve Schweinhart of America Online. 374164562Sgshapiro Warn if OperatorChars is set multiple times. OperatorChars should 374264562Sgshapiro not be set after rulesets are defined. Suggested by 374364562Sgshapiro Mitchell Blank Jr of Exec-PC. 374464562Sgshapiro Do not report temporary failure on delivery to files. In 374564562Sgshapiro interactive delivery mode, this would result in two SMTP 374664562Sgshapiro responses after the DATA command. Problem noted by 374764562Sgshapiro Nik Conwell of Boston University. 374864562Sgshapiro Check file close when mailing to files. Problem noted by Nik 374964562Sgshapiro Conwell of Boston University. 375064562Sgshapiro Avoid a segmentation fault when using the LDAP map. Patch from 375164562Sgshapiro Curtis W. Hillegas of Princeton University. 375264562Sgshapiro Always bind to the LDAP server regardless of whether you are using 375364562Sgshapiro ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of 375464562Sgshapiro @Home Network. 375564562Sgshapiro New ruleset trust_auth to determine whether a given AUTH= 375664562Sgshapiro parameter of the MAIL command should be trusted. See SMTP 375764562Sgshapiro AUTH, cf/README, and doc/op/op.ps. 375864562Sgshapiro Allow new named config file rules check_vrfy, check_expn, and 375964562Sgshapiro check_etrn for VRFY, EXPN, and ETRN commands, respectively, 376064562Sgshapiro similar to check_rcpt etc. 376164562Sgshapiro Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr}, 376264562Sgshapiro ${mail_mailer}, ${mail_host}, ${mail_addr} that hold 376364562Sgshapiro the results of parsing the RCPT and MAIL arguments, i.e. 376464562Sgshapiro the resolved triplet from $#mailer $@host $:addr. 376564562Sgshapiro From Kari Hurtta of the Finnish Meteorological Institute. 376664562Sgshapiro New macro ${client_resolve} which holds the result of the resolve 376764562Sgshapiro call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed 376864562Sgshapiro by Kari Hurtta of the Finnish Meteorological Institute. 376964562Sgshapiro New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold 377064562Sgshapiro the corresponding DSN parameter values. Proposed by 377164562Sgshapiro Mathias Herberts. 377264562Sgshapiro New macro ${msg_size} which holds the value of the SIZE= parameter, 377364562Sgshapiro i.e., usually the size of the message (in an ESMTP dialogue), 377464562Sgshapiro before the message has been collected, thereafter it holds 377564562Sgshapiro the message size as computed by sendmail (and can be used 377664562Sgshapiro in check_compat). 377764562Sgshapiro The macro ${deliveryMode} now specifies the current delivery mode 377864562Sgshapiro sendmail is using instead of the value of the DeliveryMode 377964562Sgshapiro option. 378064562Sgshapiro New macro ${ntries} holds the number of delivery attempts. 378164562Sgshapiro Drop explicit From: if same as what would be generated only if it is 378264562Sgshapiro a local address. From Motonori Nakamura of Kyoto University. 378364562Sgshapiro Write pid to file also if sendmail only processes the queue. 378464562Sgshapiro Proposed by Roy J. Mongiovi of Georgia Tech. 378564562Sgshapiro Log "low on disk space" only when necessary. 378664562Sgshapiro New macro ${load_avg} can be used to check the current load average. 378764562Sgshapiro Suggested by Scott Gifford of The Internet Ramp. 378864562Sgshapiro Return-Receipt-To: header implies DSN request if option RrtImpliesDsn 378964562Sgshapiro is set. 379064562Sgshapiro Flag -S for maps to specify the character which is substituted 379164562Sgshapiro for spaces (instead of the default given by O BlankSub). 379264562Sgshapiro Flag -D for maps: perform no lookup in deferred delivery mode. 379364562Sgshapiro This flag is set by default for the host map. Based on a 379464562Sgshapiro proposal from Ian MacPhedran of the University of Saskatchewan. 379564562Sgshapiro Open maps only on demand, not at startup. 379664562Sgshapiro Log warning about unsupported IP address families. 379764562Sgshapiro New option MaxHeadersLength allows to specify a maximum length 379864562Sgshapiro of the sum of all headers. This can be used to prevent 379964562Sgshapiro a denial-of-service attack. 380064562Sgshapiro New option MaxMimeHeaderLength which limits the size of MIME 380164562Sgshapiro headers and parameters within those headers. This option 380264562Sgshapiro is intended to protect mail user agents from buffer 380364562Sgshapiro overflow attacks. 380464562Sgshapiro Added option MaxAliasRecursion to specify the maximum depth of 380564562Sgshapiro alias recursion. 380664562Sgshapiro New flag F=6 for mailers to strip headers to seven bit. 380764562Sgshapiro Map type syslog to log the key via syslogd. 380864562Sgshapiro Entries in the alias file can be continued by putting a backslash 380964562Sgshapiro directly before the newline. 381064562Sgshapiro New option DeadLetterDrop to define the location of the system-wide 381164562Sgshapiro dead.letter file, formerly hardcoded to 381264562Sgshapiro /usr/tmp/dead.letter. If this option is not set (the 381364562Sgshapiro default), sendmail will not attempt to save to a 381464562Sgshapiro system-wide dead.letter file if it can not bounce the mail 381564562Sgshapiro to the user nor postmaster. Instead, it will rename the qf 381664562Sgshapiro file as it has in the past when the dead.letter file 381764562Sgshapiro could not be opened. 381864562Sgshapiro New option PidFile to define the location of the pid file. The 381964562Sgshapiro value of this option is macro expanded. 382064562Sgshapiro New option ProcessTitlePrefix specifies a prefix string for the 382164562Sgshapiro process title shown in 'ps' listings. 382264562Sgshapiro New macros for use with the PidFile and ProcessTitlePrefix options 382364562Sgshapiro (along with the already existing macros): 382464562Sgshapiro ${daemon_info} Daemon information, e.g. 382564562Sgshapiro SMTP+queueing@00:30:00 382664562Sgshapiro ${daemon_addr} Daemon address, e.g., 0.0.0.0 382764562Sgshapiro ${daemon_family} Daemon family, e.g., inet, inet6, etc. 382864562Sgshapiro ${daemon_name} Daemon name, e.g., MSA. 382964562Sgshapiro ${daemon_port} Daemon port, e.g., 25 383064562Sgshapiro ${queue_interval} Queue run interval, e.g., 00:30:00 383164562Sgshapiro New macros especially for virtual hosting: 383264562Sgshapiro ${if_name} hostname of interface of incoming connection. 383364562Sgshapiro ${if_addr} address of interface of incoming connection. 383464562Sgshapiro The latter is only set if the interface does not belong to the 383564562Sgshapiro loopback net. 383664562Sgshapiro If a message being accepted via a method other than SMTP and 383764562Sgshapiro would be rejected by a header check, do not send the message. 383864562Sgshapiro Suggested by Phil Homewood of Mincom Pty Ltd. 383964562Sgshapiro Don't strip comments for header checks if $>+ is used instead of $>. 384064562Sgshapiro Provide header value as quoted string in the macro 384164562Sgshapiro ${currHeader} (possibly truncated to MAXNAME). Suggested by 384264562Sgshapiro Jan Krueger of Unix-AG of University of Hannover. 384364562Sgshapiro The length of the header value is stored in ${hdrlen}. 384464562Sgshapiro H*: allows to specify a default ruleset for header checks. This 384564562Sgshapiro ruleset will only be called if the individual header does 384664562Sgshapiro not have its own ruleset assigned. Suggested by Jan 384764562Sgshapiro Krueger of Unix-AG of University of Hannover. 384864562Sgshapiro The name of the header field stored in ${hdr_name}. 384964562Sgshapiro Comments (i.e., text within parentheses) in rulesets are not 385064562Sgshapiro removed if the config file version is greater than or equal 385164562Sgshapiro to 9. For example, "R$+ ( 1 ) $@ 1" matches the 385264562Sgshapiro input "token (1)" but does not match "token". 385364562Sgshapiro Avoid removing the Content-Transfer-Encoding MIME header on 385464562Sgshapiro MIME messages. Problem noted by Sigurbjorn B. Larusson of 385564562Sgshapiro Multimedia Consumer Services. Fix from Per Hedeland of 385664562Sgshapiro Ericsson. 385764562Sgshapiro Avoid duplicate Content-Transfer-Encoding MIME header on 385864562Sgshapiro messages with 8-bit text in headers.

Problem noted by Chris Adams 386364562Sgshapiro of Renaissance Internet Services. 386464562Sgshapiro Resolving to the $#error mailer with a temporary failure code (e.g., 386564562Sgshapiro $#error $@ tempfail $: "400 Temporary failure") will now 386664562Sgshapiro queue up the message instead of bouncing it. 386764562Sgshapiro Be more liberal in acceptable responses to an SMTP RSET command as 386864562Sgshapiro standard does not provide any indication of what to do when 386964562Sgshapiro something other than 250 is received. Based on a patch 387064562Sgshapiro from Steve Schweinhart of America Online. 387164562Sgshapiro New option TrustedUser allows to specify a user who can own 387264562Sgshapiro important files instead of root. This requires HASFCHOWN. 387364562Sgshapiro Fix USERDB conditional so compiling with NEWDB or HESIOD and 387464562Sgshapiro setting USERDB=0 works. Fix from Jorg Zanger of Schock. 387564562Sgshapiro Fix another instance (similar to one in 8.9.3) of a network failure 387664562Sgshapiro being mis-logged as "Illegal Seek" instead of whatever 387764562Sgshapiro really went wrong. From John Beck of Sun Microsystems. 387864562Sgshapiro $? tests also whether the macro is non-null. 387964562Sgshapiro Print an error message if a mailer definition contains an invalid 388064562Sgshapiro equate name. 388164562Sgshapiro New mailer equate /= to specify a directory to chroot() into before 388264562Sgshapiro executing the mailer program. Suggested by Igor Vinokurov. 388364562Sgshapiro New mailer equate W= to specify the maximum time to wait for the 388464562Sgshapiro mailer to return after sending all data to it. 388564562Sgshapiro Only free memory from the process list when adding a new process 388664562Sgshapiro into a previously filled slot. Previously, the memory was 388764562Sgshapiro freed at removal time. Since removal can happen in a 388864562Sgshapiro signal handler, this may leave the memory map in an 388964562Sgshapiro inconsistent state. Problem noted by Jeff A. Earickson and 389064562Sgshapiro David Cooley of Colby College. 389164562Sgshapiro When using the UserDB @hostname catch-all, do not try to lookup 389264562Sgshapiro local users in the passwd file. The UserDB code has 389364562Sgshapiro already decided the message will be passed to another host 389464562Sgshapiro for processing. Fix from Tony Landells of Burdett 389564562Sgshapiro Buckeridge Young Limited. 389664562Sgshapiro Support LDAP authorization via either a file containing the 389764562Sgshapiro password or Kerberos V4 using the new map options 389864562Sgshapiro '-ddistinguished_name', '-Mmethod', and '-Pfilename'. The 389964562Sgshapiro distinguished_name is who to login as. The method can be 390064562Sgshapiro one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or 390164562Sgshapiro LDAP_AUTH_KRBV4. The filename is the file containing the 390264562Sgshapiro secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos 390364562Sgshapiro ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense 390464562Sgshapiro of Stanford University. 390564562Sgshapiro The ldapx map has been renamed to ldap. The use of ldapx is 390664562Sgshapiro deprecated and will be removed in a future version. 390764562Sgshapiro If the result of an LDAP search returns a multi-valued attribute 390864562Sgshapiro and the map has the column delimiter set, it turns that 390964562Sgshapiro response into a delimiter separated string. The LDAP map 391064562Sgshapiro will traverse multiple entries as well. LDAP alias maps 391164562Sgshapiro automatically set the column delimiter to the comma. 391264562Sgshapiro Based on patch from Booker Bense of Stanford University and 391364562Sgshapiro idea from Philip A. Prindeville of Mirapoint, Inc. 391464562Sgshapiro Support return of multiple values for a single LDAP lookup. The 391564562Sgshapiro values to be returned should be in a comma separated string. 391664562Sgshapiro For example, `-v "email,emailother"'. Patch from 391764562Sgshapiro Curtis W. Hillegas of Princeton University. 391864562Sgshapiro Allow the use of LDAP for alias maps. 391964562Sgshapiro If no LDAP attributes are specified in an LDAP map declaration, all 392064562Sgshapiro attributes found in the match will be returned. 392164562Sgshapiro Prevent commas in quoted strings in the AliasFile value from 392264562Sgshapiro breaking up a single entry into multiple entries. This is 392364562Sgshapiro needed for LDAP alias file specifications to allow for 392464562Sgshapiro comma separated key and value strings. 392564562Sgshapiro Keep connections to LDAP server open instead of opening and closing 392664562Sgshapiro for each lookup. To reduce overhead, sendmail will cache 392764562Sgshapiro connections such that multiple maps which use the same 392864562Sgshapiro host, port, bind DN, and authentication will only result in 392964562Sgshapiro a single connection to that host. 393064562Sgshapiro Put timeout in the proper place for USE_LDAP_INIT. 393164562Sgshapiro Be more careful about checking for errors and freeing memory on 393264562Sgshapiro LDAP lookups. 393364562Sgshapiro Use asynchronous LDAP searches to save memory and network 393464562Sgshapiro resources. 393564562Sgshapiro Do not copy LDAP query results if the map's match only flag is set. 393664562Sgshapiro Increase portability to the Netscape LDAP libraries. 393764562Sgshapiro Change the parsing of the LDAP filter specification. '%s' is still 393864562Sgshapiro replaced with the literal contents of the map lookup key -- 393964562Sgshapiro note that this means a lookup can be done using the LDAP 394064562Sgshapiro special characters. The new '%0' token can be used instead 394164562Sgshapiro of '%s' to encode the key buffer according to RFC 2254. 394264562Sgshapiro For example, if the LDAP map specification contains '-k 394364562Sgshapiro "(user=%s)"' and a lookup is done on "*", this would be 394464562Sgshapiro equivalent to '-k "(user=*)"' -- matching ANY record with a 394564562Sgshapiro user attribute. Instead, if the LDAP map specification 394664562Sgshapiro contains '-k "(user=%0)"' and a lookup is done on "*", this 394764562Sgshapiro would be equivalent to '-k "(user=\2A)"' -- matching a user 394864562Sgshapiro with the name "*". 394964562Sgshapiro New LDAP map flags: "-1" requires a single match to be returned, if 395064562Sgshapiro more than one is returned, it is equivalent to no records 395164562Sgshapiro being found; "-r never|always|search|find" sets the LDAP 395264562Sgshapiro alias dereference option; "-Z size" limits the number of 395364562Sgshapiro matches to return. 395464562Sgshapiro New option LDAPDefaultSpec allows a default map specification for 395564562Sgshapiro LDAP maps. The value should only contain LDAP specific 395664562Sgshapiro settings such as "-h host -p port -d bindDN", etc. The 395764562Sgshapiro settings will be used for all LDAP maps unless they are 395864562Sgshapiro specified in the individual map specification ('K' 395964562Sgshapiro command). This option should be set before any LDAP maps 396064562Sgshapiro are defined. 396164562Sgshapiro Prevent an NDBM alias file opening loop when the NDBM open 396264562Sgshapiro continually fails. Fix from Roy J. Mongiovi of Georgia 396364562Sgshapiro Tech. 396464562Sgshapiro Reduce memory utilization for smaller symbol table entries. In 396564562Sgshapiro particular, class entries get much smaller, which can be 396664562Sgshapiro important if you have large classes. 396764562Sgshapiro On network-related temporary failures, record the hostname which 396864562Sgshapiro gave error in the queued status message. Requested by 396964562Sgshapiro Ulrich Windl of the Universitat Regensburg. 397064562Sgshapiro Add new F=% mailer flag to allow for a store and forward 397164562Sgshapiro configuration. Mailers which have this flag will not attempt 397271345Sgshapiro delivery on initial receipt of a message or on queue runs 397364562Sgshapiro unless the queued message is selected using one of the 397464562Sgshapiro -qI/-qR/-qS queue run modifiers or an ETRN request. Code 397564562Sgshapiro provided by Philip Guenther of Gustavus Adolphus College. 397664562Sgshapiro New option ControlSocketName which, when set, creates a daemon 397764562Sgshapiro control socket. This socket allows an external program to 397864562Sgshapiro control and query status from the running sendmail daemon 397964562Sgshapiro via a named socket, similar to the ctlinnd interface to the 398064562Sgshapiro INN news server. Access to this interface is controlled by 398164562Sgshapiro the UNIX file permissions on the named socket on most UNIX 398264562Sgshapiro systems (see sendmail/README for more information). An 398364562Sgshapiro example control program is provided as contrib/smcontrol.pl. 398464562Sgshapiro Change the default values of QueueLA from 8 to (8 * numproc) and 398564562Sgshapiro RefuseLA from 12 to (12 * numproc) where numproc is the 398664562Sgshapiro number of processors online on the system (if that can be 398764562Sgshapiro determined). For single processor machines, this change 398864562Sgshapiro has no effect. 398964562Sgshapiro Don't return body of message to postmaster on "Too many hops" bounces. 399064562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 399164562Sgshapiro Give more detailed DSN descriptions for some cases. Patch from 399264562Sgshapiro Motonori Nakamura of Kyoto University. 399364562Sgshapiro Logging of alias, forward file, and UserDB expansion now happens 399464562Sgshapiro at LogLevel 11 or higher instead of 10 or higher. 399564562Sgshapiro Logging of an envelope's complete delivery (the "done" message) now 399664562Sgshapiro happens at LogLevel 10 or higher instead of 11 or higher. 399764562Sgshapiro Logging of TCP/IP or UNIX standard input connections now happens at 399864562Sgshapiro LogLevel 10 or higher. Previously, only TCP/IP connections 399964562Sgshapiro were logged, and on at LogLevel 12 or higher. Setting 400064562Sgshapiro LogLevel to 10 will now assist users in tracking frequent 400164562Sgshapiro connection-based denial of service attacks. 400264562Sgshapiro Log basic information about authenticated connections at LogLevel 400364562Sgshapiro 10 or higher. 400464562Sgshapiro Log SMTP Authentication mechanism and author when logging the sender 400564562Sgshapiro information (from= syslog line). 400664562Sgshapiro Log the DSN code for each recipient if one is available as a new 400764562Sgshapiro equate (dsn=). 400864562Sgshapiro Macro expand PostmasterCopy and DoubleBounceAddress options. 4009120256Sgshapiro New "ph" map for performing ph queries in rulesets, see 4010120256Sgshapiro sendmail/README for details. Contributed by Mark Roth 4011120256Sgshapiro of the University of Illinois at Urbana-Champaign. 401264562Sgshapiro Detect temporary lookup failures in the host map if looking up a 401364562Sgshapiro bracketed IP address. Problem noted by Kari Hurtta of the 401464562Sgshapiro Finnish Meteorological Institute. 401564562Sgshapiro Do not report a Remote-MTA on local deliveries. Problem noted by 401664562Sgshapiro Kari Hurtta of the Finnish Meteorological Institute. 401764562Sgshapiro When a forward file points to an alias which runs a program, run 401864562Sgshapiro the program as the default user and the default group, not 401964562Sgshapiro the forward file user. This change also assures the 402064562Sgshapiro :include: directives in aliases are also processed using 402164562Sgshapiro the default user and group. Problem noted by Sergiu 402264562Sgshapiro Popovici of DNT Romania. 402364562Sgshapiro Prevent attempts to save a dead.letter file for a user with 402464562Sgshapiro no home directory (/no/such/directory). Problem noted by 402564562Sgshapiro Michael Brown of Finnigan FT/MS. 402664562Sgshapiro Include message delay and number of tries when logging that a 402764562Sgshapiro message has been completely delivered (LogLevel of 10 or 402864562Sgshapiro above). Suggested by Nick Hilliard of Ireland Online. 402964562Sgshapiro Log the sender of a message even if none of the recipients were 403064562Sgshapiro accepted. If some of the recipients were rejected, it is 403164562Sgshapiro helpful to know the sender of the message. 403264562Sgshapiro Check the root directory (/) when checking a path for safety. 403364562Sgshapiro Problem noted by John Beck of Sun Microsystems. 403464562Sgshapiro Prevent multiple responses to the DATA command if DeliveryMode is 403564562Sgshapiro interactive and delivering to an alias which resolves to 403664562Sgshapiro multiple files. 403764562Sgshapiro Macros in the helpfile are expanded if the helpfile version is 2 or 403864562Sgshapiro greater (see below); the help function doesn't print the 403964562Sgshapiro version of sendmail any longer, instead it is placed in 404064562Sgshapiro the helpfile ($v). Suggested by Chuck Foster of UUNET 404164562Sgshapiro PIPEX. Additionally, comment lines (starting with #) are 404264562Sgshapiro skipped and a version line (#vers) is introduced. The 404364562Sgshapiro helpfile version for 8.10.0 is 2, if no version or an older 404464562Sgshapiro version is found, a warning is logged. The '#vers' 404564562Sgshapiro directive should be placed at the top of the help file. 404664562Sgshapiro Use fsync() when delivering to a file to guarantee the delivery to 404764562Sgshapiro disk succeeded. Suggested by Nick Christenson. 404864562Sgshapiro If delivery to a file is unsuccessful, truncate the file back to its 404964562Sgshapiro length before the attempt. 405064562Sgshapiro If a forward points to a filename for delivery, change to the 405164562Sgshapiro user's uid before checking permissions on the file. This 405264562Sgshapiro allows delivery to files on NFS mounted directories where 405364562Sgshapiro root is remapped to nobody. Problem noted by Harald 405464562Sgshapiro Daeubler of Universitaet Ulm. 405564562Sgshapiro purgestat and sendmail -bH purge only expired (Timeout.hoststatus) 405664562Sgshapiro host status files, not all files. 405764562Sgshapiro Any macros stored in the class $={persistentMacros} will be saved 405864562Sgshapiro in the queue file for the message and set when delivery 405964562Sgshapiro is attempted on the queued item. Suggested by Kyle Jones of 406064562Sgshapiro Wonderworks Inc. 406164562Sgshapiro Add support for storing information between rulesets using the new 406264562Sgshapiro macro map class. This can be used to store information 406364562Sgshapiro between queue runs as well using $={persistentMacros}. 406464562Sgshapiro Based on an idea from Jan Krueger of Unix-AG of University 406564562Sgshapiro of Hannover. 406664562Sgshapiro New map class arith to allow for computations in rules. The 406764562Sgshapiro operation (+, -, *, /, l (for less than), and =) is given 406864562Sgshapiro as key. The two operands are specified as arguments; the 406964562Sgshapiro lookup returns the result of the computation. For example, 407064562Sgshapiro "$(arith l $@ 4 $@ 2 $)" will return "FALSE" and 407164562Sgshapiro "$(arith + $@ 4 $@ 2 $)" will return "6". 407264562Sgshapiro Add new syntax for header declarations which decide whether to 407364562Sgshapiro include the header based on a macro rather than a mailer 407464562Sgshapiro flag: 407564562Sgshapiro H?${MyMacro}?X-My-Header: ${MyMacro} 407664562Sgshapiro This should be used along with $={persistentMacros}. 407764562Sgshapiro It can be used for adding headers to a message based on 407864562Sgshapiro the results of check_* and header check rulesets. 407964562Sgshapiro Allow new named config file rule check_eoh which is called after 408064562Sgshapiro all of the headers have been collected. The input to the 408164562Sgshapiro ruleset the number of headers and the size of all of the 408264562Sgshapiro headers in bytes separated by $|. This ruleset along with 408364562Sgshapiro the macro storage map can be used to correlate information 408464562Sgshapiro gathered between headers and to check for missing headers. 408564562Sgshapiro See cf/README or doc/op/op.ps for an example. 408664562Sgshapiro Change the default for the MeToo option to True to correspond 408764562Sgshapiro to the clarification in the DRUMS SMTP Update spec. This 408864562Sgshapiro option is deprecated and will be removed from a future 408964562Sgshapiro version. 409064562Sgshapiro Change the sendmail binary default for SendMimeErrors to True. 409164562Sgshapiro Change the sendmail binary default for SuperSafe to True. 409264562Sgshapiro Display ruleset names in debug and address test mode output 409364562Sgshapiro if referencing a named ruleset. 409464562Sgshapiro New mailer equate m= which will limit the number of messages 409564562Sgshapiro delivered per connection on an SMTP or LMTP mailer. 409664562Sgshapiro Improve QueueSortOrder=Host by reversing the hostname before 409764562Sgshapiro using it to sort. Now all the same domains are really run 409864562Sgshapiro through the queue together. If they have the same MX host, 409964562Sgshapiro then they will have a much better opportunity to use the 410064562Sgshapiro connection cache if available. This should be a reasonable 410164562Sgshapiro performance improvement. Patch from Randall Winchester of 410264562Sgshapiro the University of Maryland. 410364562Sgshapiro If a message is rejected by a header check ruleset, log who would 410464562Sgshapiro have received the message if it had not been rejected. 410564562Sgshapiro New "now" value for Timeout.queuereturn to bounce entries from the 410664562Sgshapiro queue immediately. No delivery attempt is made. 410764562Sgshapiro Increase sleeping time exponentially after too many "bad" commands 410864562Sgshapiro up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}- 410964562Sgshapiro COMMANDS). 411064562Sgshapiro New option ClientPortOptions similar to DaemonPortOptions 411164562Sgshapiro but for outgoing connections. 411264562Sgshapiro New suboptions for DaemonPortOptions: Name (a name used for 411364562Sgshapiro error messages and logging) and Modifiers, i.e. 411464562Sgshapiro a require authentication 411564562Sgshapiro b bind to interface through which mail has 411664562Sgshapiro been received 411764562Sgshapiro c perform hostname canonification 411864562Sgshapiro f require fully qualified hostname 411964562Sgshapiro h use name of interface for outgoing HELO 412064562Sgshapiro command 412164562Sgshapiro C don't perform hostname canonification 412264562Sgshapiro E disallow ETRN (see RFC 2476) 412364562Sgshapiro New suboption for ClientPortOptions: Modifiers, i.e. 412464562Sgshapiro h use name of interface for HELO command 412564562Sgshapiro The version number for queue files (qf) has been incremented to 4. 412664562Sgshapiro Log unacceptable HELO/EHLO domain name attempts if LogLevel is set 412764562Sgshapiro to 10 or higher. Suggested by Rick Troxel of the National 412864562Sgshapiro Institutes of Health. 412964562Sgshapiro If a mailer dies, print the status in decimal instead of octal 413064562Sgshapiro format. Suggested by Michael Shapiro of Sun Microsystems. 413164562Sgshapiro Limit the length of all MX records considered for delivery to 8k. 413264562Sgshapiro Move message priority from sender to recipient logging. Suggested by 413364562Sgshapiro Ulrich Windl of the Universitat Regensburg. 413464562Sgshapiro Add support for Berkeley DB 3.X. 413564562Sgshapiro Add fix for Berkeley DB 2.X fcntl() locking race condition. 413664562Sgshapiro Requires a post-2.7.5 version of Berkeley DB. 413764562Sgshapiro Support writing traffic log (sendmail -X option) to a FIFO. 413864562Sgshapiro Patch submitted by Rick Heaton of Network Associates, Inc. 413964562Sgshapiro Do not ignore Timeout settings in the .cf file when a Timeout 414064562Sgshapiro sub-options is set on the command line. Problem noted by 414164562Sgshapiro Graeme Hewson of Oracle. 414264562Sgshapiro Randomize equal preference MX records each time delivery is 414364562Sgshapiro attempted via a new connection to a host instead of once per 414464562Sgshapiro session. Suggested by Scott Salvidio of Compaq. 414564562Sgshapiro Implement enhanced status codes as defined by RFC 2034. 414664562Sgshapiro Add [hostname] to class w for the names of all interfaces unless 414764562Sgshapiro DontProbeInterfaces is set. This is useful for sending mails 414864562Sgshapiro to hosts which have dynamically assigned names. 414964562Sgshapiro If a message is bounced due to bad MIME conformance, avoid bouncing 415064562Sgshapiro the bounce for the same reason. If the body is not 8-bit 415164562Sgshapiro clean, and EightBitMode isn't set to pass8, the body will 415264562Sgshapiro not be included in the bounce. Problem noted by Valdis 415364562Sgshapiro Kletnieks of Virginia Tech. 415464562Sgshapiro The timeout for sending a message via SMTP has been changed from 415564562Sgshapiro '${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which 415664562Sgshapiro simply checks for progress on sending data every 5 minutes. 415764562Sgshapiro This will detect the inability to send information quicker 415864562Sgshapiro and reduce the number of processes simply waiting to 415964562Sgshapiro timeout. 416064562Sgshapiro Prevent a segmentation fault on systems which give a partial filled 416164562Sgshapiro interface address structure when loading the system network 416264562Sgshapiro interface addresses. Fix from Reinier Bezuidenhout of 416364562Sgshapiro Nanoteq. 416464562Sgshapiro Add a compile-time configuration macro, MAXINTERFACES, which 416564562Sgshapiro indicates the number of interfaces to read when probing 416664562Sgshapiro for hostnames and IP addresses for class w ($=w). The 416764562Sgshapiro default value is 512. Based on idea from Reinier 416864562Sgshapiro Bezuidenhout of Nanoteq. 416964562Sgshapiro If the RefuseLA option is set to 0, do not reject connections based 417064562Sgshapiro on load average. 417164562Sgshapiro Allow ruleset 0 to have a name. Problem noted by Neil Rickert of 417264562Sgshapiro Northern Illinois University. 417364562Sgshapiro Expand the Return-Path: header at delivery time, after "owner-" 417464562Sgshapiro envelope splitting has occurred. 417564562Sgshapiro Don't try to sort the queue if there are no entries. Patch from 417664562Sgshapiro Luke Mewburn from RMIT University. 417764562Sgshapiro Add a "/quit" command to address test mode. 417864562Sgshapiro Include the proper sender in the UNIX "From " line and Return-Path: 417964562Sgshapiro header when undeliverable mail is saved to ~/dead.letter. 418064562Sgshapiro Problem noted by Kari Hurtta of the Finnish Meteorological 418164562Sgshapiro Institute. 418264562Sgshapiro The contents of a class can now be copied to another class using 418364562Sgshapiro the syntax: "C{Dest} $={Source}". This would copy all of 418464562Sgshapiro the items in class $={Source} into the class $={Dest}. 418564562Sgshapiro Include original envelope's error transcript in bounces created for 418664562Sgshapiro split (owner-) envelopes to see the original errors when 418764562Sgshapiro the recipients were added. Based on fix from Motonori 418864562Sgshapiro Nakamura of Kyoto University. 418964562Sgshapiro Show reason for permanent delivery errors directly after the 419064562Sgshapiro addresses. From Motonori Nakamura of Kyoto University. 419164562Sgshapiro Prevent a segmentation fault when bouncing a split-envelope 419264562Sgshapiro message. Patch from Motonori Nakamura of Kyoto University. 419364562Sgshapiro If the specification for the queue run interval (-q###) has a 419464562Sgshapiro syntax error, consider the error fatal and exit. 419564562Sgshapiro Pay attention to CheckpointInterval during LMTP delivery. Problem 419664562Sgshapiro noted by Motonori Nakamura of Kyoto University. 419764562Sgshapiro On operating systems which have setlogin(2), use it to set the 419864562Sgshapiro login name to the RunAsUserName when starting as a daemon. 419964562Sgshapiro This is for delivery to programs which use getlogin(). 420064562Sgshapiro Based on fix from Motonori Nakamura of Kyoto University. 420164562Sgshapiro Differentiate between "command not implemented" and "command 420264562Sgshapiro unrecognized" in the SMTP dialogue. 420364562Sgshapiro Strip returns from forward and include files.

Problem noted by Per 428164562Sgshapiro Hedeland of Ericsson. 428264562Sgshapiro mailq displays unprintable characters in addresses as their octal 428364562Sgshapiro representation and a leading backslash. This avoids problems 428464562Sgshapiro with "unprintable" characters. Problem noted by Michal 428564562Sgshapiro Zalewski of the "Internet for Schools" project (IdS). 428664562Sgshapiro The mail line length limit (L= equate) was adding the '!' indicator 428764562Sgshapiro one character past the limit. This would cause subsequent 428864562Sgshapiro hops to break the line again. The '!' is now placed in 428964562Sgshapiro the last column of the limit if the line needs to be broken. 429064562Sgshapiro Problem noted by Joe Pruett of Q7 Enterprises.

Prindeville of Enteka Enterprise Technology 452464562Sgshapiro Services. 452564562Sgshapiro CONFIG: MAILER(`cyrus') was not preserving case for mail folder 452664562Sgshapiro names. Problem noted by Randall Winchester of Swales 452764562Sgshapiro Aerospace. 452864562Sgshapiro CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags 452964562Sgshapiro for the relay mailer. Suggested by Doug Hughes of Auburn 453064562Sgshapiro University and Brian Candler. 453164562Sgshapiro CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path: 453264562Sgshapiro header) by default. Suggested by Per Hedeland of Ericsson. 453364562Sgshapiro CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host]. 453464562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 453564562Sgshapiro Institute. 453664562Sgshapiro CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS; 453764562Sgshapiro i.e., to set, add, or delete flags. 453864562Sgshapiro CONFIG: If SMTP AUTH is used then relaying is allowed for any user 453964562Sgshapiro who authenticated via a "trusted" mechanism, i.e., one that 454064562Sgshapiro is defined via TRUST_AUTH_MECH(`list of mechanisms'). 454164562Sgshapiro CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay 454264562Sgshapiro after check_rcpt and allows for exceptions from the checks. 454364562Sgshapiro CONFIG: Map declarations have been moved into their associated 454464562Sgshapiro feature files to allow greater flexibility in use of 454564562Sgshapiro sequence maps. Suggested by Per Hedeland of Ericsson. 454664562Sgshapiro CONFIG: New macro LOCAL_MAILER_EOL to override the default end of 454764562Sgshapiro line string for the local mailer. Requested by Il Oh of 454864562Sgshapiro Willamette Industries, Inc. 454964562Sgshapiro CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is 455064562Sgshapiro converted to <user@d> 455164562Sgshapiro CONFIG: Reject bogus return address of <@@hostname>, generated by 455264562Sgshapiro Sun's older, broken configuration files. 455364562Sgshapiro CONFIG: FEATURE(`nullclient') now provides the full rulesets of a 455464562Sgshapiro normal configuration, allowing anti-spam checks to be 455564562Sgshapiro performed. 455664562Sgshapiro CONFIG: Don't return a permanent error (Relaying denied) if 455764562Sgshapiro ${client_name} can't be resolved just temporarily. 455864562Sgshapiro Suggested by Kari Hurtta of the Finnish Meteorological 455964562Sgshapiro Institute. 456064562Sgshapiro CONFIG: Change numbered rulesets into named (which still can 456164562Sgshapiro be accessed by their numbers). 456264562Sgshapiro CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial 456364562Sgshapiro which describes whether to disallow "!" in the local part 456464562Sgshapiro of an address. 456564562Sgshapiro CONFIG: Call Local_localaddr from localaddr (S5) which can be used 456664562Sgshapiro to rewrite an address from a mailer which has the F=5 flag 456764562Sgshapiro set. If the ruleset returns a mailer, the appropriate 456864562Sgshapiro action is taken, otherwise the returned tokens are ignored. 456964562Sgshapiro CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4 457064562Sgshapiro and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4. 457164562Sgshapiro The latter is kept around for backward compatibility. 457264562Sgshapiro CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries, 457364562Sgshapiro where "D.S.N" is an RFC 1893 compliant error code. 457464562Sgshapiro CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX). 457564562Sgshapiro CONFIG: Remove second space between username and date in UNIX From_ 457664562Sgshapiro line. Noted by Allan E Johannesen of Worcester Polytechnic 457764562Sgshapiro Institute. 457864562Sgshapiro CONFIG: Make sure all of the mailers have complete T= equates. 457964562Sgshapiro CONFIG: Extend FEATURE(`local_procmail') so it can now take 458064562Sgshapiro arguments overriding the mailer program, arguments, and 458164562Sgshapiro mailer definition flags. This makes it possible to use 458264562Sgshapiro other programs such as maildrop for local delivery. 458364562Sgshapiro CONFIG: Emit warning if FEATURE(`local_lmtp') or 458464562Sgshapiro FEATURE(`local_procmail') is given after MAILER(`local'). 458564562Sgshapiro Patch from Richard A.

Problem noted by Ezequiel H. Panepucci of 460164562Sgshapiro Yale University. 460264562Sgshapiro DEVTOOLS: 'Build -M' will display the obj.* directory which will 460364562Sgshapiro be used for building. 460464562Sgshapiro DEVTOOLS: 'Build -A' will display the architecture that would be 460564562Sgshapiro used for a fresh build. 460664562Sgshapiro DEVTOOLS: New variable confRANLIB, set automatically by configure.sh. 460764562Sgshapiro DEVTOOLS: New variable confRANLIBOPTS for the options to send to 460864562Sgshapiro ranlib. 460964562Sgshapiro DEVTOOLS: 'Build -O <path>' will have the object files build in 461064562Sgshapiro <path>/obj.*. Suggested by Bryan Costales of Exactis. 461164562Sgshapiro DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the 461264562Sgshapiro building of the man pages when defined. Suggested by Bryan 461364562Sgshapiro Costales. 461464562Sgshapiro DEVTOOLS: New variables confNO_HELPFILE_INSTALL and 461564562Sgshapiro confNO_STATISTICS_INSTALL which will prevent the 461664562Sgshapiro installation of the sendmail helpfile and statistics file 461764562Sgshapiro respectively. Suggested by Bryan Costales. 461864562Sgshapiro DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske 461964562Sgshapiro of Siemens Business Services. 462064562Sgshapiro DEVTOOLS: New variable confSTDIO_TYPE which defines the type of 462164562Sgshapiro stdio library. The new buffered file I/O depends on the 462264562Sgshapiro Torek stdio library. This option can be either portable or 462364562Sgshapiro torek. 462464562Sgshapiro DEVTOOLS: New variables confSRCADD and confSMSRCADD which 462564562Sgshapiro correspond to confOBJADD and confSMOBJADD respectively. 462664562Sgshapiro They should contain the C source files for the object files 462764562Sgshapiro listed in confOBJADD and confSMOBJADD. These file names 462864562Sgshapiro will be passed to the 'make depend' stage of compilation. 462964562Sgshapiro DEVTOOLS: New program specific variables for each of the programs 463064562Sgshapiro in the sendmail distribution. Each has the form 463164562Sgshapiro `conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'. 463264562Sgshapiro The new variables are conf_prog_ENVDEF, conf_prog_LIBS, 463364562Sgshapiro conf_prog_SRCADD, and conf_prog_OBJADD. 463464562Sgshapiro DEVTOOLS: Build system redesign. This should have little affect on 463564562Sgshapiro building the distribution, but documentation on the changes 463664562Sgshapiro are in devtools/README. 463764562Sgshapiro DEVTOOLS: Don't allow 'Build -f file' if an object directory already 463864562Sgshapiro exists. Suggested by Valdis Kletnieks of Virginia Tech. 463964562Sgshapiro DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies 464064562Sgshapiro the path to the sendmail source directory. confSRCDIR is a 464164562Sgshapiro new variable which identifies the root of the source 464264562Sgshapiro directories for all of the programs in the distribution. 464364562Sgshapiro DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build 464464562Sgshapiro time. They can both still be overridden by setting the m4 464564562Sgshapiro macro. 464664562Sgshapiro DEVTOOLS: confSBINGRP now defaults to bin instead of kmem. 464764562Sgshapiro DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for 464864562Sgshapiro build configurations, and places objects in obj.prefix.*/. 464964562Sgshapiro Complains as 'Build -f file' does for existing object 465064562Sgshapiro directories. Suggested by Tom Smith of Digital Equipment 465164562Sgshapiro Corporation. 465264562Sgshapiro DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted 465364562Sgshapiro manual pages in the directory tree specified by 465464562Sgshapiro confMANROOTMAN. 465564562Sgshapiro DEVTOOLS: If formatting the manual pages fails, copy in the 465664562Sgshapiro preformatted pages from the distribution. The new variable 465764562Sgshapiro confCOPY specifies the copying program. 465864562Sgshapiro DEVTOOLS: Defining confFORCE_RMAIL will install rmail without 465964562Sgshapiro question. Suggested by Terry Lambert of Whistle 466064562Sgshapiro Communications. 466164562Sgshapiro DEVTOOLS: confSTFILE and confHFFILE can be used to change the names 466264562Sgshapiro of the installed statistics and help files, respectively. 466364562Sgshapiro DEVTOOLS: Remove spaces in `uname -r` output when determining 466464562Sgshapiro operating system identity. Problem noted by Erik 466564562Sgshapiro Wachtenheim of Dartmouth College. 466664562Sgshapiro DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that 466764562Sgshapiro will be search for the libraries specified in confLIBSEARCH. 466864562Sgshapiro Defaults to "/lib /usr/lib /usr/shlib". 466964562Sgshapiro DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying 467064562Sgshapiro how to strip binaries. These are used by the new 467164562Sgshapiro install-strip target. 467264562Sgshapiro DEVTOOLS: New config file site.post.m4 which is included after 467364562Sgshapiro the others (if it exists). 467464562Sgshapiro DEVTOOLS: Change order of LIBS: first product specific libraries 467564562Sgshapiro then the default ones. 467690792Sgshapiro MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local 467764562Sgshapiro as local delivery agent without LMTP mode, use 467864562Sgshapiro MODIFY_MAILER_FLAGS(`LOCAL', `+S') 467964562Sgshapiro to set the S flag. 468064562Sgshapiro MAIL.LOCAL: Do not reject addresses which would otherwise be 468164562Sgshapiro accepted by sendmail. Suggested by Neil Rickert of 468264562Sgshapiro Northern Illinois University. 468364562Sgshapiro MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise 468464562Sgshapiro 8BITMIME in the LHLO response. Suggested by Kari Hurtta of 468564562Sgshapiro the Finnish Meteorological Institute. 468664562Sgshapiro MAIL.LOCAL: Add support for the maillock() routines by defining 468764562Sgshapiro MAILLOCK when compiling. Also requires linking with 468864562Sgshapiro -lmail. Patch from Neil Rickert of Northern Illinois 468964562Sgshapiro University. 469064562Sgshapiro MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is 469164562Sgshapiro defined when compiling. Automatically set for Solaris 2.3 469264562Sgshapiro and later. Patch from Neil Rickert of Northern Illinois 469364562Sgshapiro University. 469464562Sgshapiro MAIL.LOCAL: Move the initialization of the 'notifybiff' address 469564562Sgshapiro structure to the beginning of the program. This ensures that 469664562Sgshapiro the getservbyname() is done before any seteuid to a possibly 469764562Sgshapiro unauthenticated user. If you are using NIS+ and secure RPC 469864562Sgshapiro on a Solaris system, this avoids syslog messages such as, 469964562Sgshapiro "authdes_refresh: keyserv(1m) is unable to encrypt session 470064562Sgshapiro key." Patch from Neil Rickert of Northern Illinois 470164562Sgshapiro University. 470264562Sgshapiro MAIL.LOCAL: Support group writable mail spool files when MAILGID is 470364562Sgshapiro set to the gid to use (-DMAILGID=6) when compiling. 470464562Sgshapiro Patch from Neil Rickert of Northern Illinois University. 470564562Sgshapiro MAIL.LOCAL: When a mail message included lines longer than 2046 470664562Sgshapiro characters (in LMTP mode), mail.local split the incoming 470764562Sgshapiro line up into 2046-character output lines (excluding the 470864562Sgshapiro newline). If an input line was 2047 characters long 470964562Sgshapiro (excluding CR-LF) and the last character was a '.', 471064562Sgshapiro mail.local saw it as the end of input, transfered it to the 471164562Sgshapiro user mailbox and tried to write an `ok' back to sendmail. 471264562Sgshapiro If the message was much longer, both sendmail and 471364562Sgshapiro mail.local would deadlock waiting for each other to read 471464562Sgshapiro what they have written. Problem noted by Peter Jeremy of 471564562Sgshapiro Alcatel Australia Limited. 471664562Sgshapiro MAIL.LOCAL: New option -b to return a permanent error instead of a 471764562Sgshapiro temporary error if a mailbox exceeds quota. Suggested by 471864562Sgshapiro Neil Rickert of Northern Illinois University. 471964562Sgshapiro MAIL.LOCAL: The creation of a lockfile is subject to a global 472064562Sgshapiro timeout to avoid starvation. 472164562Sgshapiro MAIL.LOCAL: Properly parse addresses with multiple quoted 472264562Sgshapiro local-parts. Problem noted by Ronald F. Guilmette of 472364562Sgshapiro Infinite Monkeys & Co. 472464562Sgshapiro MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR. 472564562Sgshapiro MAILSTATS: New -p option to invoke program mode in which stats are 472664562Sgshapiro printed in a machine readable fashion and the stats file 472764562Sgshapiro is reset. Patch from Kevin Hildebrand of the University 472864562Sgshapiro of Maryland. 472964562Sgshapiro MAKEMAP: If running as root, automatically change the ownership of 473064562Sgshapiro generated maps to the TrustedUser as specified in the 473164562Sgshapiro sendmail configuration file. 473264562Sgshapiro MAKEMAP: New -C option to accept an alternate sendmail 473364562Sgshapiro configuration file to use for finding the TrustedUser 473464562Sgshapiro option. 473564562Sgshapiro MAKEMAP: New -u option to dump (unmap) a database. Based on 473664562Sgshapiro code contributed by Roy Mongiovi of Georgia Tech. 473764562Sgshapiro MAKEMAP: New -e option to allow empty values. Suggested by Philip 473864562Sgshapiro A. Prindeville of Enteka Enterprise Technology Services. 473964562Sgshapiro MAKEMAP: Compile cleanly on 64-bit operating systems. Problem 474064562Sgshapiro noted by Gerald Rinske of Siemens Business Services. 474164562Sgshapiro OP.ME: Correctly document interaction between F=S and U= mailer 474264562Sgshapiro equates. Problem noted by Bob Halley of Internet Engines. 474364562Sgshapiro OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle 474464562Sgshapiro Corporation UK. 474564562Sgshapiro OP.ME: The Timeout [r] option was incorrectly listed as "safe" 474664562Sgshapiro (e.g., sendmail would not drop root privileges if the 474764562Sgshapiro option was specified on the command line). Problem noted 474864562Sgshapiro by Todd C. Miller of Courtesan Consulting. 474964562Sgshapiro PRALIASES: Handle the hash and btree map specifications for 475064562Sgshapiro Berkeley DB. Patch from Brian J. Coan of the 475164562Sgshapiro Institute for Global Communications. 475264562Sgshapiro PRALIASES: Read the sendmail.cf file for the location(s) of the 475364562Sgshapiro alias file(s) if the -f option is not used. Patch from 475464562Sgshapiro John Beck of Sun Microsystems. 475564562Sgshapiro PRALIASES: New -C option to specify an alternate sendmail 475664562Sgshapiro configuration file to use for finding alias file(s). Patch 475764562Sgshapiro from John Beck of Sun Microsystems. 475864562Sgshapiro SMRSH: allow shell commands echo, exec, and exit. Allow command 475964562Sgshapiro lists using || and &&.

Sites 520638032Speter which need the ability to override security can use the 520738032Speter DontBlameSendmail option. See the README file for more 520838032Speter information. 520938032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 521038032Speter if maps or alias files are in world writable directories. 521138032Speter This fixes the change added to 8.8.6 to prevent links in these 521238032Speter world writable directories. 521338032Speter SECURITY: Make sure ServiceSwitchFile option file is not a link if 521438032Speter it is in a world writable directory. 521538032Speter SECURITY: Never pass a tty to a mailer -- if a mailer can get at the 521638032Speter tty it may be able to push bytes back to the senders input. 521738032Speter Unfortunately this breaks -v mode.

After this number is reached, sendmail 527738032Speter starts returning "452 Too many recipients" to all RCPT 527838032Speter commands. This can be used to limit the number of recipients 527938032Speter per envelope (in particular, to discourage use of the server 528038032Speter for spamming). Note: a better approach is to restrict 528138032Speter relaying entirely. 528238032Speter Fixed pointer initialization for LDAP lmap struct, fixed -s option 528338032Speter to ldapx map and added timeout for ldap_open call to 528438032Speter avoid hanging sendmail in the event of hung LDAP servers. 528538032Speter Patch from Booker Bense of Stanford University. 528638032Speter Allow multiple -qI, -qR, or -qS queue run limiters.

Problem noted by Aidan Nichol 530538032Speter of Procter & Gamble. 530638032Speter The LDAP map -s flag was not properly parsed and the error message 530764562Sgshapiro given included the remainder of the arguments instead of 530838032Speter solely the argument in error. Problem noted by Aidan Nichol 530938032Speter of Procter & Gamble. 531038032Speter New DontBlameSendmail option. This option allows administrators to 531138032Speter bypass some of sendmail's file security checks at the expense 531238032Speter of system security.

In particular, if you 534838032Speter have lots of virtual interfaces, this option will speed up 534938032Speter startup. However, unless you make other arrangements, mail 535038032Speter sent to those addresses will be bounced. 535138032Speter Automatically create alias databases if they don't exist and 535238032Speter AutoRebuildAliases is set. 535338032Speter Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command. 535438032Speter Suggested by Christophe Wolfhugel of the Institut Pasteur. 535538032Speter Add PrivacyOptions=noverb flag to disable the SMTP VERB command. 535638032Speter When determining the client host name ($&{client_name} macro), do 535738032Speter a forward (A) DNS lookup on the result of the PTR lookup 535838032Speter and compare results. If they differ or if the PTR lookup 535938032Speter fails, &{client_name} will contain the IP address 536064562Sgshapiro surrounded by square brackets (e.g., [127.0.0.1]). 536138032Speter New map flag: -Tx appends "x" to lookups that return temporary failure 536238032Speter (i.e, it is like -ax for the temporary failure case, in 536338032Speter contrast to the success case). 536438032Speter New syntax to do limited checking of header syntax. A config line 536538032Speter of the form: 536638032Speter HHeader: $>Ruleset 536738032Speter causes the indicated Ruleset to be invoked on the Header 536838032Speter when read. This ruleset works like the check_* rulesets -- 536938032Speter that is, it can reject mail on the basis of the contents. 537038032Speter Limit the size of the HELO/EHLO parameter to prevent spammers 537138032Speter from hiding their connection information in Received: 537238032Speter headers. 537338032Speter When SingleThreadDelivery is active, deliveries to locked hosts 537438032Speter are skipped. This will cause the delivering process to 537538032Speter try the next MX host or queue the message if no other MX 537638032Speter hosts are available. Suggested by Alexander Litvin. 537738032Speter The [FILE] mailer type now delivers to the file specified in the 537838032Speter A= equate of the mailer definition instead of $u. It also 537938032Speter obeys all of the F= mailer flags such as the MIME 538038032Speter 7/8 bit conversion flags. This is useful for defining 538138032Speter a mailer which delivers to the same file regardless of the 538264562Sgshapiro recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail). 538338032Speter Do not assume the identity of a remote connection is root@localhost 538438032Speter if the remote connection closes the socket before the 538538032Speter remote identity can be queried. 538638032Speter Change semantics of the F=S mailer flag back to 8.7.5 behavior. 538738032Speter Some mailers, including procmail, require that the real 538838032Speter uid is left unchanged by sendmail. Problem noted by Per 538938032Speter Hedeland of Ericsson. 539038032Speter No longer is the src/obj*/Makefile selected from a large list -- it 539138032Speter is now generated using the information in BuildTools/OS/ -- 539238032Speter some of the details are determined dynamically via 539338032Speter BuildTools/bin/configure.sh. 539438032Speter The other programs in the sendmail distribution -- mail.local, 539538032Speter mailstats, makemap, praliases, rmail, and smrsh -- now use 539638032Speter the new Build method which creates an operating system 539738032Speter specific Makefile using the information in BuildTools. 539838032Speter Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e., 539938032Speter a failure on one message won't affect future messages to the 540038032Speter same host). This is necessary if the remote host sends 540138032Speter a 451 error if the domain of the sender does not resolve 540238032Speter as is common in anti-spam configurations. Problem noted 540338032Speter by Mitchell Blank Jr of Exec-PC. 540438032Speter New "discard" mailer for check_* rulesets and header checking 540538032Speter rulesets. If one of the above rulesets resolves to the 540638032Speter $#discard mailer, the commands will be accepted but the 540738032Speter message will be completely discarded after it is accepting. 540838032Speter This means that even if only one of the recipients 540938032Speter resolves to the $#discard mailer, none of the recipients 541038032Speter will receive the mail. Suggested by Brian Kantor. 541138032Speter All but the last cloned envelope of a split envelope were queued 541238032Speter instead of being delivered.

Problem noted by 544638032Speter Lutz Euler of Lavielle EDV Systemberatung GmbH & Co. 544738032Speter Include a magic number and version in the StatusFile for the 544838032Speter mailstats command. 544938032Speter Record the number of rejected and discarded messages in the 545038032Speter StatusFile for display by the mailstats command. Patch 545138032Speter from Randall Winchester of the University of Maryland. 545238032Speter IDENT returns where the OSTYPE field equals "OTHER" now list the 545338032Speter user portion as IDENT:username@site instead of 545438032Speter username@site to differentiate the two. Suggested by 545538032Speter Kari Hurtta of the Finnish Meteorological Institute. 545638032Speter Enforce timeout for LDAP queries. Patch from Per Hedeland of 545738032Speter Ericsson. 545838032Speter Change persistent host status filename substitution so '/' is 545938032Speter replaced by ':' instead of '|' to avoid clashes. Also 546038032Speter avoid clashes with hostnames with leading dots. Fix from 546138032Speter Mitchell Blank Jr. of Exec-PC. 546238032Speter If the system lock table is full, only attempt to create a new 546338032Speter queue entry five times before giving up. Previously, it 546438032Speter was attempted indefinitely which could cause the partition 546538032Speter to run out of inodes. Problem noted by Suzie Weigand of 546638032Speter Stratus Computer, Inc. 546738032Speter In verbose mode, warn if the sendmail.cf version is less than the 546838032Speter currently supported version. 546938032Speter Sorting for QueueSortOrder=host is now case insensitive. Patch 547038032Speter from Randall S. Winchester of the University of Maryland. 547138032Speter Properly quote a full name passed via the -F command line option, 547238032Speter the Full-Name: header, or the NAME environment variable if 547338032Speter it contains characters which must be quoted. Problem noted 547438032Speter by Kari Hurtta of the Finnish Meteorological Institute. 547538032Speter Avoid possible race condition that unlocked a mail job before 547638032Speter releasing the transcript file on systems that use flock(2). 547738032Speter In some cases, this might result in a "Transcript Unavailable" 547838032Speter message in error bounces. 547938032Speter Accept SMTP replies which contain only a reply code and no 548038032Speter accompanying text. Problem noted by Fernando Fraticelli of 548138032Speter Digital Equipment Corporation. 548238032Speter Portability: 548338032Speter AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura 548438032Speter of Kyoto University. 548538032Speter AIX 4.2 requires <userpw.h> before <usersec.h>.

From Guillermo Freige of 550638032Speter Gobernacion de la Pcia de Buenos Aires and Paul 550738032Speter Fischer of BTG, Inc. 550838032Speter SunOS 4.X does not include memmove(). Patch from 550938032Speter Per Hedeland of Ericsson. 551038032Speter SunOS 5.7 includes getloadavg() function for determining 551138032Speter load average. Patch from John Beck of Sun 551238032Speter Microsystems. 551338032Speter CONFIG: Increment version number of config file. 551438032Speter CONFIG: add DATABASE_MAP_TYPE to set the default type of database 551538032Speter map for the various maps. The default is hash. Patch from 551638032Speter Robert Harker of Harker Systems. 551738032Speter CONFIG: new confEBINDIR m4 variable for defining the executable 551838032Speter directory for certain programs. 551938032Speter CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for 552038032Speter local mail delivery. By the default, /usr/libexec/mail.local 552138032Speter is used. This is expected to be the mail.local shipped 552238032Speter with 8.9 which is LMTP capable. The path is based on the 552338032Speter new confEBINDIR m4 variable. 552438032Speter CONFIG: Use confEBINDIR in determining path to smrsh for 552538032Speter FEATURE(smrsh). Note that this changes the default from 552638032Speter /usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the 552738032Speter old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh). 552838032Speter CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to 552938032Speter include $z/.forward.$w+$h and $z/.forward+$h which allow 553038032Speter the user to setup different .forward files for 553138032Speter user+detail addressing. 553238032Speter CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES, 553338032Speter and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage, 553438032Speter DontProbeInterfaces, and DontBlameSendmail options. 553538032Speter CONFIG: by default do not allow relaying (that is, accepting mail 553638032Speter from outside your domain and sending it to another host 553738032Speter outside your domain). 553838032Speter CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from 553938032Speter any site to any site. 554038032Speter CONFIG: new FEATURE(relay_entire_domain) allows any host in your 554138032Speter domain as defined by the 'm' class ($=m) to relay. 554238032Speter CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on 554338032Speter the MX records of the host portion of an incoming recipient. 554438032Speter CONFIG: new FEATURE(access_db) which turns on the access database 554577349Sgshapiro feature. This database gives you the ability to allow 554638032Speter or refuse to accept mail from specified domains for 554738032Speter administrative reasons. By default, names that are listed 554838032Speter as "OK" in the access db are domain names, not host names. 554938032Speter CONFIG: new confCR_FILE m4 variable for defining the name of the file 555038032Speter used for class 'R'. Defaults to /etc/mail/relay-domains. 555138032Speter CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file) 555238032Speter to add items to class 'R' ($=R) for hosts allowed to relay. 555338032Speter CONFIG: new FEATURE(relay_hosts_only) to change the behavior 555438032Speter of FEATURE(access_db) and class 'R' to lookup individual 555538032Speter host names only. 555638032Speter CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient 555738032Speter using % addressing is used, e.g. user%site@othersite, 555838032Speter and othersite is in class 'R', the check_rcpt ruleset 555938032Speter will strip @othersite and recheck user@site for relaying. 556038032Speter This feature changes that behavior. It should not be 556138032Speter needed for most installations. 556238032Speter CONFIG: new FEATURE(relay_local_from) to allow relaying if the 556338032Speter domain portion of the mail sender is a local host. This 556438032Speter should only be used if absolutely necessary as it opens 556538032Speter a window for spammers. Patch from Randall S. Winchester of 556638032Speter the University of Maryland. 556738032Speter CONFIG: new FEATURE(blacklist_recipients) turns on the ability to 556838032Speter block incoming mail destined for certain recipient 556938032Speter usernames, hostnames, or addresses. 557038032Speter CONFIG: By default, MAIL FROM: commands in the SMTP session will be 557138032Speter refused if the host part of the argument to MAIL FROM: cannot 557238032Speter be located in the host name service (e.g., DNS). 557338032Speter CONFIG: new FEATURE(accept_unresolvable_domains) accepts 557438032Speter unresolvable hostnames in MAIL FROM: SMTP commands. 557538032Speter CONFIG: new FEATURE(accept_unqualified_senders) accepts 557638032Speter MAIL FROM: senders which do not include a domain. 557738032Speter CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the 557838032Speter Realtime Blackhole List. You can specify the RBL name 557938032Speter server to contact by specifying it as an optional argument. 558038032Speter The default is rbl.maps.vix.com. For details, see 558138032Speter http://maps.vix.com/rbl/. 558238032Speter CONFIG: Call Local_check_relay, Local_check_mail, and 558338032Speter Local_check_rcpt from check_relay, check_mail, and 558438032Speter check_rcpt. Users with local rulesets should place the 558538032Speter rules using LOCAL_RULESETS. If a Local_check_* ruleset 558638032Speter returns $#OK, the message is accepted. If the ruleset 558738032Speter returns a mailer, the appropriate action is taken, else 558838032Speter the return of the ruleset is ignored. 558938032Speter CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by 559038032Speter default to support file, :include:, and program deliveries. 559138032Speter CONFIG: Remove the default for confDEF_USER_ID so the binary can 559238032Speter pick the proper default value. See the SECURITY note 559338032Speter above for more information. 559438032Speter CONFIG: FEATURE(nodns) now warns the user that the feature is a 559538032Speter no-op. Patch from Kari Hurtta of the Finnish 559638032Speter Meteorological Institute. 559738032Speter CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to 559838032Speter daemon since DEC's /bin/mail will drop the envelope 559938032Speter sender if run as mailnull. See the Digital UNIX section 560038032Speter of src/README for more information. Problem noted by 560138032Speter Kari Hurtta of the Finnish Meteorological Institute. 560238032Speter CONFIG: .cf files are now stored in the same directory with the 560338032Speter .mc files instead of in the obj directory. 560464562Sgshapiro CONFIG: New options confSINGLE_LINE_FROM_HEADER, 560538032Speter confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for 560638032Speter setting SingleLineFromHeader, AllowBogusHELO, and 560738032Speter MustQuoteChars respectively. 560838032Speter MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout. This 560938032Speter SMTP-like protocol allows detailed reporting of delivery 561038032Speter status on a per-user basis. Code donated by John Myers of 561138032Speter CMU (now of Netscape). 561238032Speter MAIL.LOCAL: HP-UX support from Randall S. Winchester of the 561364562Sgshapiro University of Maryland.

Problem noted by Greg Nichols of Wind 574138032Speter River Systems. 574238032Speter If SingleThreadDelivery was enabled and the remote server returned a 574338032Speter protocol error on the DATA command, the connection would be 574438032Speter closed but the persistent host status file would not be 574538032Speter unlocked so other sendmail processes could not deliver to 574638032Speter that host. Problem noted by Peter Wemm of DIALix. 574738032Speter If queueing up a message due to an expensive mailer, don't increment 574838032Speter the number of delivery attempts or set the last delivery 574938032Speter attempt time so the message will be delivered on the next 575038032Speter queue run regardless of MinQueueAge. Problem noted by 575138032Speter Brian J. Coan of the Institute for Global Communications. 575238032Speter Authentication warnings of "Processed from queue _directory_" and 575338032Speter "Processed by _username_ with -C _filename_" would be logged 575438032Speter with the incorrect timestamp. Problem noted by Kari E.

Problem noted by 575838032Speter Jon Lewis of Florida Digital Turnpike. 575938032Speter If class dbm maps are rebuilt, sendmail will now detect this and 576038032Speter reopen the map. Previously, they could give stale 576138032Speter results during a single message processing (but would 576238032Speter recover when the next message was received). Fix from 576338032Speter Joe Pruett of Q7 Enterprises. 576438032Speter Do not log failures such as "User unknown" on -bv or SMTP VRFY 576538032Speter requests. Problem noted by Kari E.

Problem noted by Kari E. Hurtta of the 577038032Speter Finnish Meteorological Institute. 577138032Speter Use "localhost" instead of "[UNIX: localhost]" when connecting to 577238032Speter sendmail via a UNIX pipe. This will allow rulesets using 577338032Speter $&{client_name} to process without sending the string through 577438032Speter dequote. Problem noted by Alan Barrett of Internet Africa. 577538032Speter A combination of deferred delivery mode, a double bounce situation, 577638032Speter and the inability to save a bounce message to 577738032Speter /var/tmp/dead.letter would cause sendmail to send a bounce 577838032Speter to postmaster but not remove the offending envelope from the 577938032Speter queue causing it to create a new bounce message each time the 578038032Speter queue was run. Problem noted by Brad Doctor of Net Daemons 578138032Speter Associates. 578238032Speter Remove newlines from hostname information returned via DNS. There are 578338032Speter no known security implications of newlines in hostnames as 578438032Speter sendmail filters newlines in all vital areas; however, this 578538032Speter could cause confusing error messages. 578638032Speter Starting with sendmail 8.8.6, mail sent with the '-t' option would be 578738032Speter rejected if any of the specified addresses were bad. This 578838032Speter behavior was modified to only reject the bad addresses and not 578938032Speter the entire message.

From Tetsu Ushijima of the 591038032Speter Tokyo Institute of Technology. 591138032Speter Fix race condition that could cause the body of a message to be 591238032Speter lost (so only the header was delivered).

Based on a patch from Steve Schweinhart of 591638032Speter Results Computing. 591738032Speter If a qf file was found in a mail queue directory that had a problem 591838032Speter (wrong ownership, bad format, etc.) and the file name was 591938032Speter exactly MAXQFNAME bytes long, then instead of being tried 592038032Speter once, it would be tried on every queue run. Problem noted 592138032Speter by Bryan Costales of Mercury Mail. 592238032Speter If the system supports an st_gen field in the status structure, 592338032Speter include it when reporting that a file has changed after open. 592438032Speter This adds a new compile flag, HAS_ST_GEN (0/1 option). 592538032Speter This out to be checked as well as reported, since it is 592638032Speter theoretically possible for an attacker to remove a file after 592738032Speter it is opened and replace it with another file that has the 592838032Speter same i-number, but some filesystems (notably AFS) return 592938032Speter garbage in this field, and hence always look like the file 593038032Speter has changed. As a practical matter this is not a security 593138032Speter problem, since the files can be neither hard nor soft links, 593238032Speter and on no filesystem (that I am aware of) is it possible to 593338032Speter have two files on the same filesystem with the same i-number 593438032Speter simultaneously. 593538032Speter Delete the root Makefile from the distribution -- it is only for 593638032Speter use internally, and does not work at customer sites. 593738032Speter Fix botch that caused the second MAIL FROM: command in a single 593838032Speter transaction to clear the entire transaction.

This makes it possible to create a root 602438032Speter owned file in an arbitrary directory by inserting the symlink 602538032Speter into a writable directory after the initial lstat(2) check 602638032Speter determined that the file did not exist. The only verified 602738032Speter example of a system having these odd semantics for O_EXCL 602838032Speter and symbolic links was HP-UX prior to version 9.07. Most 602938032Speter systems do not have the problem, since a exclusive create 603038032Speter of a file disallows symbolic links. Systems that have been 603138032Speter verified to NOT have the problem include AIX 3.x, *BSD, 603238032Speter DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris, 603338032Speter and Ultrix. This is a potential exposure on systems that 603438032Speter have this bug and which do not have a MAILER-DAEMON alias 603538032Speter pointing at a legitimate account, since this will cause old 603638032Speter mail to be dropped in /var/tmp/dead.letter. 603738032Speter SECURITY: Problems can occur on poorly managed systems, specifically, 603838032Speter if maps or alias files are in world writable directories. 603938032Speter If your system has alias maps in writable directories, it 604038032Speter is potentially possible for an attacker to replace the .db 604138032Speter (or .dir and .pag) files by symbolic links pointing at 604238032Speter another database; this can be used either to expose 604338032Speter information (e.g., by pointing an alias file at /etc/spwd.db 604438032Speter and probing for accounts), or as a denial-of-service attack 604538032Speter (by trashing the password database). The fix disallows 604638032Speter symbolic links entirely when rebuilding alias files or on 604738032Speter maps that are in writable directories, and always warns on 604838032Speter writable directories; 8.9 will probably consider writable 604938032Speter directories to be fatal errors. This does not represent an 605038032Speter exposure on systems that have alias files in unwritable 605138032Speter system directories. 605238032Speter SECURITY: disallow .forward or :include: files that are links (hard 605338032Speter or soft) if the parent directory (or any directory in the 605438032Speter path) is writable by anyone other than the owner. This is 605538032Speter similar to the previous case for user files. This change 605638032Speter should not affect most systems, but is necessary to prevent 605738032Speter an attacker who can write the directory from pointing such 605838032Speter files at other files that are readable only by the owner. 605938032Speter SECURITY: Tighten safechown rules: many systems will say that they 606038032Speter have a safe (restricted to root) chown even on files that 606138032Speter are mounted from another system that allows owners to give 606238032Speter away files. The new rules are very strict, trusting file 606338032Speter ownership only in those few cases where the system has 606438032Speter been verified to be at least as paranoid as necessary. 606538032Speter However, it is possible to relax the rules to partially 606638032Speter trust the ownership if the directory path is not world or 606738032Speter group writable. This might allow someone who has a legitimate 606838032Speter :include: file (referenced directly from /etc/aliases) to 606938032Speter become another non-root user if the :include: file is in a 607038032Speter non-writable directory on an NFS-mounted filesystem where 607138032Speter the local system says that giveaway is denied but it is 607238032Speter actually permitted. I believe this to be a very small set 607338032Speter of cases. If in doubt, do not point :include: aliases at 607438032Speter NFS-mounted filesystems. 607538032Speter SECURITY: When setting a numeric group id using the RunAsUser option 607638032Speter (e.g., "O RunAsUser=10:20", the group id would not be set. 607738032Speter Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha 607838032Speter group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine. 607938032Speter The user id was still set properly.

Note that this should really 612338032Speter be fixed in the zone file for the domain. Problem noted by 612438032Speter Joe Rhett of Navigist, Inc. 612538032Speter If a map fails (e.g., DNS times out) on all recipient addresses, mark 612638032Speter the message as having been tried; otherwise the next queue 612738032Speter run will not realize that this is a second attempt and will 612838032Speter retry immediately. Problem noted by Bryan Costales of 612938032Speter Mercury Mail. 613038032Speter If the clock is set backwards, and a MinQueueAge is set, no jobs 613138032Speter will be run until the later setting of the clock is reached. 613238032Speter "Problem" (I use the term loosely) noted by Eric Hagberg of 613338032Speter Morgan Stanley. 613438032Speter If the load average rises above the cutoff threshold (above which 613538032Speter sendmail will not process the queue at all) during a queue 613638032Speter run, abort the queue run immediately. Problem noted by 613738032Speter Bryan Costales of Mercury Mail. 613838032Speter The variable queue processing algorithm (based on the message size, 613938032Speter number of recipients, message precedence, and job age) was 614038032Speter non-functional -- either the entire queue was processed or 614138032Speter none of the queue was processed. The updated algorithm 614238032Speter does no queue run if a single recipient zero size job will 614338032Speter not be run. 614438032Speter If there is a fatal ("panic") message that will cause sendmail to 614538032Speter die immediately, never hold the error message for future 614638032Speter printing. 614738032Speter Force ErrorMode=print in -bt mode so that all errors are printed 614838032Speter regardless of the setting of the ErrorMode option in the 614938032Speter configuration file. Patch from Gregory Neil Shapiro. 615038032Speter New compile flag HASSTRERROR says that this OS has the strerror(3) 615138032Speter routine available in one of the libraries. Use it in conf.h. 615238032Speter The -m (match only) flag now works on host class maps. 615338032Speter If class hash or btree maps are rebuilt, sendmail will now detect 615438032Speter this and reopen the map. Previously, they could give 615538032Speter erroneous results during a single message processing 615638032Speter (but would recover when the next message was received). 615738032Speter Don't delete zero length queue files when doing queue runs until the 615838032Speter files are at least ten minutes old. This avoids a potential 615938032Speter race condition: the creator creates the qf file, getting back 616038032Speter a file descriptor. The queue runner locks it and deletes it 616138032Speter because it is zero length. The creator then writes the 616238032Speter descriptor that is now for a disconnected file, and the 616338032Speter job goes away. Based on a suggestion by Bryan Costales. 616438032Speter When determining the "validated" host name ($_ macro), do a forward 616538032Speter (A) DNS lookup on the result of the PTR lookup and compare 616638032Speter results. If they differ or if the PTR lookup fails, tag the 616738032Speter address as "may be forged". 616838032Speter Log null connections (i.e., hosts that connect but do not do any 616938032Speter substantive activity on the connection before disconnecting; 617038032Speter "substantive" is defined to be MAIL, EXPN, VRFY, or ETRN. 617138032Speter Always permit "writes" to /dev/null regardless of the link count. 617238032Speter This is safe because /dev/null is special cased, and no open 617338032Speter or write is ever actually attempted. Patch from Villy Kruse 617438032Speter of TwinCom. 617538032Speter If a message cannot be sent because of a 552 (exceeded storage 617638032Speter allocation) response to the MAIL FROM:<>, and a SIZE= parameter 617738032Speter was given, don't return the body in the bounce, since there 617838032Speter is a very good chance that the message will double-bounce. 617938032Speter Fix possible line truncation if a quoted-printable had an =00 escape 618038032Speter in the body. Problem noted by Charles Karney of the Princeton 618138032Speter Plasma Physics Laboratory. 618238032Speter Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses. 618338032Speter Problem noted by Kari Hurtta of the Finnish Meteorological 618438032Speter Institute. 618538032Speter The MaxDaemonChildren option wasn't applying to queue runs as 618638032Speter documented. Note that this increases the potential denial 618738032Speter of service problems with this option: an attacker can 618838032Speter connect many times, and thereby lock out queue runs as well 618938032Speter as incoming connections. If you use this option, you should 619038032Speter run the "sendmail -bd" and "sendmail -q30m" jobs separately 619138032Speter to avoid this attack. Failure to limit noted by Matthew 619238032Speter Dillon of BEST Internet Communications. 619338032Speter Always give a message in newaliases if alias files cannot be 619438032Speter opened instead of failing silently. Suggested by Gregory 619538032Speter Neil Shapiro. This change makes the code match the O'Reilly 619638032Speter book (2nd edition). 619738032Speter Some older versions of the resolver could return with h_errno == -1 619838032Speter if no name server could be reached, causing mail to bounce 619938032Speter instead of queueing. Treat this like TRY_AGAIN. Fix from 620038032Speter John Beck of SunSoft. 620138032Speter If a :include: file is owned by a user that does not have an entry 620238032Speter in the passwd file, sendmail could dereference a null pointer. 620338032Speter Problem noted by Satish Mynam of Sun Microsystems. 620438032Speter Take precautions to make sure that the SMTP protocol cannot get out 620538032Speter of sync if (for example) an alias file cannot be opened. 620638032Speter Fix a possible race condition that can cause a SIGALRM to come in 620738032Speter immediately after a SIGHUP, causing the new sendmail to die. 620838032Speter Avoid possible hang on SVr3 systems when doing child reaping. Patch 620938032Speter from Villy Kruse of TwinCom. 621038032Speter Ignore improperly formatted SMTP reply codes. Previously these were 621138032Speter partially processed, which could cause confusing error 621238032Speter returns. 621338032Speter Fix possible bogus pointer dereference when doing ldapx map lookups 621438032Speter on some architectures. 621538032Speter Portability: 621638032Speter A/UX: from Jim Jagielski of NASA/GSFC. 621738032Speter glibc: SOCK_STREAM was changed from a #define to an enum, 621838032Speter thus breaking #ifdef SOCK_STREAM. Only option seems 621938032Speter to be to assume SOCK_STREAM if __GNU_LIBRARY__ is 622038032Speter defined. Problem reported by A Sun of the University 622138032Speter of Washington. 622238032Speter Solaris: use SIOCGIFNUM to get the number of interfaces on 622338032Speter the system rather than guessing at compile time. 622438032Speter Patch contributed by John Beck of Sun Microsystems. 622538032Speter Intel Paragon: from Wendy Lin of Purdue University. 622638032Speter GNU Hurd: from Miles Bader of the GNU project. 622738032Speter RISC/os 4.50 from Harlan Stenn of PFCS Corporation. 622838032Speter ISC Unix: wait never returns if SIGCLD signals are blocked. 622938032Speter Unfortunately releasing them opens a race condition, 623038032Speter but there appears to be no fix for this. Patch from 623138032Speter Gregory Neil Shapiro. 623238032Speter BIND 8.1 for IPv6 compatibility from John Kennedy. 623338032Speter Solaris: a bug in strcasecmp caused characters with the 623438032Speter high order bit set to apparently randomly match 623538032Speter letters -- for example, $| (0233) matches "i" and "I". 623638032Speter Problem noted by John Gregson of the University of 623738032Speter Cambridge. 623838032Speter IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From 623938032Speter Kari Hurtta. 624038032Speter IRIX 6.x: Create Makefiles for systems that claim to be 624138032Speter IRIX64 but are 6.2 or higher (so use the regular 624238032Speter IRIX Makefile). 624338032Speter IRIX 6.x: Fix load average computation on 64 bit kernels. 624438032Speter Problem noted by Eric Hagberg of Morgan Stanley. 624538032Speter CONFIG: Some canonification was still done for UUCP-like addresses 624638032Speter even if FEATURE(nocanonify) was set. Problem pointed out by 624738032Speter Brian Candler. 624838032Speter CONFIG: In some cases UUCP mailers wouldn't properly recognize all 624938032Speter local names as local. Problem noted by Jeff Polk of BSDI; 625038032Speter fix provided by Gregory Neil Shapiro. 625138032Speter CONFIG: The "local:user" syntax entries in mailertables and other 625238032Speter "mailer:user" syntax locations returned an incorrect value 625338032Speter for the $h macro. Problem noted by Gregory Neil Shapiro. 625438032Speter CONFIG: Retain "+detail" information when forwarding mail to a 625538032Speter MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip 625638032Speter Guenther of Gustavus Adolphus College. 625738032Speter CONFIG: Make sure user+detail works for FEATURE(virtusertable); 625838032Speter rules are the same as for aliasing. Based on a patch from 625938032Speter Gregory Neil Shapiro. 626038032Speter CONFIG: Break up parsing rules into several pieces; this should 626138032Speter have no functional change in this release, but makes it 626238032Speter possible to have better anti-spam rulesets in the future. 626338032Speter CONFIG: Disallow double dots in host names to avoid having the 626438032Speter HostStatusDirectory store status under the wrong name. 626538032Speter In some cases this can be used as a denial-of-service attack. 626638032Speter Problem noted by Ron Jarrell of Virginia Tech, patch from 626738032Speter Gregory Neil Shapiro. 626838032Speter CONFIG: Don't use F=m (multiple recipients per invocation) for 626938032Speter MAILER(procmail), but do pass F=Pn9 (include Return-Path:, 627038032Speter don't include From_, and convert to 8-bit). Suggestions 627138032Speter from Kimmo Suominen and Roderick Schertler. 627264562Sgshapiro CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were 627338032Speter being masqueraded as though FEATURE(masquerade_entire_domain) 627438032Speter was specified, even when it wasn't. 627538032Speter MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft. 627638032Speter MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't 627738032Speter "slip in" a symbolic link between the lstat(2) call and the 627838032Speter exclusive open. This is only a problem on System V derived 627938032Speter systems that allow an exclusive create on files that are 628038032Speter symbolic links pointing nowhere. 628138032Speter MAIL.LOCAL: If the final mailbox close() failed, the user id was 628238032Speter not reset back to root, which on some systems would cause 628338032Speter later mailboxes to fail. Also, any partial message would 628438032Speter not be truncated, which could result in repeated deliveries. 628538032Speter Problem noted by Bruce Evans via Peter Wemm (FreeBSD 628638032Speter developers). 628738032Speter MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar 628838032Speter change to the sendmail map code was made in 8.8.3. Problem 628938032Speter noted by Gregory Neil Shapiro. 629038032Speter MAKEMAP: Give warnings on file problems such as map files that are 629190792Sgshapiro symbolic links; although makemap is not set-user-ID root, it is 629238032Speter often run as root and hence has the potential for the same 629338032Speter sorts of problems as alias rebuilds. 629438032Speter MAKEMAP: Change compilation so that it will link properly on 629538032Speter NEXTSTEP. 629638032Speter CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf. 629738032Speter Accept an optional list of arguments following the server 629838032Speter name for the ETRN arguments to use (instead of $=w). Other 629938032Speter miscellaneous bug fixes. From Christian von Roques via 630038032Speter John Beck of Sun Microsystems. 630138032Speter CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This 630238032Speter Perl script converts GECOS information in the /etc/passwd 630338032Speter file into aliases, allowing for faster access to full name 630438032Speter lookups; it is also clever about adding aliases (to root) 630538032Speter for system accounts. 630638032Speter NEW FILES: 630738032Speter src/safefile.c 630838032Speter cf/ostype/gnuhurd.m4 630938032Speter cf/ostype/irix6.m4 631038032Speter contrib/passwd-to-alias.pl 631138032Speter src/Makefiles/Makefile.IRIX64.6.1 631238032Speter src/Makefiles/Makefile.IRIX64.6.x 631338032Speter RENAMED FILES: 631438032Speter src/Makefiles/Makefile.IRIX.6.2 => Makefile.IRIX.6.x 631538032Speter src/Makefiles/Makefile.IRIX64 => Makefile.IRIX64.6.0 631638032Speter 631764562Sgshapiro8.8.5/8.8.5 1997/01/21 631838032Speter SECURITY: Clear out group list during startup. Without this, sendmail 631938032Speter will continue to run with the group permissions of the caller, 632038032Speter even if RunAsUser is specified. 632138032Speter SECURITY: Make purgestat (-bH) be root-only. This is not in response 632238032Speter to any known attack, but it's best to be conservative. 632338032Speter Suggested by Peter Wemm of DIALix. 632438032Speter SECURITY: Fix buffer overrun problem in MIME code that has possible 632538032Speter security implications. Patch from Alex Garthwaite of the 632638032Speter University of Pennsylvania. 632738032Speter Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'") 632838032Speter would truncate the address after "Full". Although the -f 632938032Speter syntax is incorrect (since it is in the envelope, it 633038032Speter shouldn't have comments and full names), the failure mode 633138032Speter was unnecessarily awful. 633238032Speter Fix a possible null pointer dereference when converting 8-bit data 633338032Speter to a 7-bit format. Problem noted by Jim Hutchins of 633438032Speter Sandia National Labs and David James of British Telecom. 633538032Speter Clear out stale state that affected F=9 on SMTP mailers in queue 633638032Speter runs. Although this really shouldn't be used (F=9 is for 633738032Speter final delivery only, and using it on an SMTP mailer makes 633838032Speter it possible for a message to be converted from 8->7->8->7 633938032Speter bits several times), it shouldn't have failed with a syserr. 634038032Speter Problem noted by Eric Hagberg of Morgan Stanley. 634138032Speter _Really_ fix the multiple :maildrop code in the user database 634238032Speter module. Patch from Roy Mongiovi of Georgia Tech. 634338032Speter Let F lines in the configuration file actually read root-only 634438032Speter files if the configuration file is safe. Based on a 634538032Speter patch from Keith Reynolds of SCO. 634638032Speter ETRN followed by QUIT would hold the connection open until the queue 634738032Speter run completed. Problem noted by Truck Lewis of TDK 634838032Speter Semiconductor Corp. 634938032Speter It turns out that despite the documentation, the TCP wrappers library 635038032Speter does _not_ log rejected connections. Do the logging ourselves. 635138032Speter Problem noted by Fletcher Mattox of the University of Texas 635238032Speter at Austin. 635338032Speter If sendmail finds a qf file in its queue directory that is an unknown 635438032Speter version (e.g., when backing out to an old version), the 635538032Speter error is reported on every queue run. Change it to only 635638032Speter give the error once (and rename the qf => Qf). Patch from 635738032Speter William A. Gianopoulos of Raytheon Company. 635838032Speter Start a new session when doing background delivery; currently it 635938032Speter ignored signals but didn't start a new signal, that caused 636038032Speter some problems if a background process tried to send mail 636138032Speter under certain circumstances. Problem noted by Eric Hagberg 636238032Speter of Morgan Stanley; fix from Kari Hurtta. 636338032Speter Simplify test for skipping a queue run to just check if the current 636438032Speter load average is >= the queueing load average. Previously 636538032Speter the check factored in some other parameters that caused it 636638032Speter to essentially never skip the queue run. Patch from Bryan 636738032Speter Costales. 636838032Speter If the SMTP server is running in "nullserver" mode (that is, it is 636938032Speter rejecting all commands), start sleeping after MAXBADCOMMAND 637038032Speter (25) commands; this helps prevent a bad guy from putting 637138032Speter you into a tight loop as a denial-of-service attack. Based 637238032Speter on an e-mail conversation with Brad Knowles of AOL. 637338032Speter Slow down when too many "light weight" commands have been issued; 637438032Speter this helps prevent a class of denial-of-service attacks. 637538032Speter The current values and defaults are: 637638032Speter MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR 637738032Speter MAXHELOCOMMANDS 3 HELO, EHLO 637838032Speter MAXVRFYCOMMANDS 6 VRFY, EXPN 637938032Speter MAXETRNCOMMANDS 8 ETRN 638038032Speter These will probably be configurable in a future release. 638138032Speter On systems that have uid_t typedefed to be an unsigned short, programs 638238032Speter that had the F=S flag and no U= equate would be invoked with 638338032Speter the real uid set to 65535 rather than being left unchanged. 638438032Speter In some cases, NOTIFY=NEVER was not being honored. Problem noted 638538032Speter by Steve Hubert of the University of Washington, Seattle. 638638032Speter Mail that was Quoted-Printable encoded and had a soft line break on 638738032Speter the last line (i.e., an incomplete continuation) had the last 638838032Speter line dropped. Since this appears to be illegal it isn't 638938032Speter clear what to do with it, but flushing the last line seems 639038032Speter to be a better "fail soft" approach. Based on a patch from 639138032Speter Eric Hagberg. 639238032Speter If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a 639338032Speter bogus HELO command still causes the "Polite people say HELO 639438032Speter first" error message. Problem pointed out by Chris Thomas 639538032Speter of UCLA; patch from John Beck of SunSoft. 639638032Speter Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set 639771345Sgshapiro in PrivacyOptions.

Problem noted by Ronan KERYELL 643738032Speter of Centre de Recherche en Informatique de l'�cole Nationale 643838032Speter Sup�rieure des Mines de Paris (CRI-ENSMP). 643938032Speter CONFIG: Clean up handling of "local:" syntax in relay specifications 644038032Speter such as LUSER_RELAY. This change permits the following 644138032Speter syntaxes: ``local:'' will send to the same user on the 644238032Speter local machine (e.g., in a mailertable entry for "host", 644338032Speter ``local:'' will cause an address addressed to user@host to 644438032Speter go to user on the local machone). ``local:user'' will send 644538032Speter to the named user on the local machine. ``local:user@host'' 644638032Speter is equivalent to ``local:user'' (the host is ignored). In 644738032Speter all cases, the original user@host is passed in $@ (i.e., the 644838032Speter detail information). Inspired by a report from Michael Fuhr. 644938032Speter CONFIG: Strip quotes from the first word of an "error:" host 645038032Speter indication. This lets you set (for example) the LUSER_RELAY 645138032Speter to be ``error:\"5.1.1\" Your Message Here''. Note the use 645238032Speter of the \" so that the resulting string is properly quoted. 645338032Speter Problem noted by Gregory Neil Shapiro of WPI. 645438032Speter OP.ME: documentation was inconsistent about whether sendmail did a 645538032Speter NOOP or a RSET to probe the connection (it does a RSET). 645638032Speter Inconsistency noted by Deeran Peethamparam. 645738032Speter OP.ME: insert additional blank pages so it will print properly on 645838032Speter a duplex printer.

The solution is to disallow any 646538032Speter files that have hard links -- this will affect .forward, 646638032Speter :include:, and output files. Problem noted by Terry 646738032Speter Kyriacopoulos of Interlog Internet Services. As a 646838032Speter workaround, set UnsafeGroupWrites -- always a good idea. 646938032Speter SECURITY: the TryNullMXList (w) option should not be safe -- if it 647038032Speter is, it is possible to do a denial-of-service attack on 647138032Speter MX hosts that rely on the use of the null MX list. There 647238032Speter is no danger if you have this option turned off (the default). 647338032Speter Problem noted by Dan Bernstein. Also, make the DontInitGroups 647438032Speter unsafe. I know of no specific attack against this, although 647538032Speter a denial-of-service attack is probably possible, but in theory 647638032Speter you should not be able to safely tweak anything that affects 647738032Speter the permissions that are used when mail is delivered. 647838032Speter Purgestat could go into an infinite loop if one of the host status 647938032Speter directories somehow became empty. Problem noted by Roy 648038032Speter Mongiovi of Georgia Tech. 648138032Speter Processes got "lost" when counting children due to a race condition. 648238032Speter This caused "proc_list_probe: lost pid" messages to be logged. 648338032Speter Problem noted by several people. 648438032Speter On systems with System V SIGCLD child signal semantics (notably AIX 648538032Speter and HP-UX), mail transactions would print the message "451 648638032Speter SMTP-MAIL: lost child: No child processes". Problem noted 648738032Speter by several people. 648838032Speter Miscellaneous compiler warnings on picky compilers (or when setting 648938032Speter gcc to high warning levels). From Tom Moore of NCR Corp. 649038032Speter SMTP protocol errors, and most errors on MAIL FROM: lines should 649138032Speter not be persistent between runs, since they are based on the 649238032Speter message rather than the host. Problem noted by Matt Dillon 649338032Speter of Best Internet Communications. 649438032Speter The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore 649538032Speter of NCR (a.k.a., AT&T Global Information Solutions). 649638032Speter Avoid the possibility of having a child daemon run to completion 649738032Speter (including closing the SMTP socket) before the parent has 649838032Speter had a chance to close the socket; this can cause the parent 649938032Speter to hang for a long time waiting for the socket to drain. 650038032Speter Patch from Don Lewis of TDK Semiconductor. 650138032Speter If the fork() failed in a queue run, the queue runners would not be 650238032Speter rescheduled (so queue runs would stop). Patch from Don Lewis. 650338032Speter Some error conditions in ETRN could cause output without an SMTP 650438032Speter status code. Problem noted by Don Lewis. 650538032Speter Multiple :maildrop addresses in the user database didn't work properly. 650638032Speter Patch from Roy Mongiovi of Georgia Tech. 650738032Speter Add ".db" automatically onto any user database spec that does not 650838032Speter already have it; this is for consistency with makemap, the 650938032Speter K line, and the documentation. Inconsistency pointed out 651038032Speter by Roy Mongiovi. 651138032Speter Allow sendmail to be properly called in nohup mode. Patch from 651238032Speter Kyle Jones of UUNET. 651338032Speter Change ETRN to ignore but still update host status files; previously 651438032Speter it would ignore them and not save the updated status, which 651538032Speter caused stale information to be maintained. Based on a patch 651638032Speter from Christopher Davis of Kapor Enterprises Inc. Also, have 651738032Speter ETRN ignore the MinQueueAge option. 651838032Speter Patch long term host status to recover more gracefully from an empty 651938032Speter host status file condition. Patch from NAKAMURA Motonori 652038032Speter of Kyoto University. 652138032Speter Several patches to signal handling code to fix potential race 652238032Speter conditions from Don Lewis. 652338032Speter Make it possible to compile with -DDAEMON=0 (previously it had some 652438032Speter compile errors). This turns DAEMON, QUEUE, and SMTP into 652538032Speter 0/1 compilation flags. Note that DAEMON is an obsolete 652638032Speter compile flag; use NETINET instead. Solution based on a 652738032Speter patch from Bryan Costales. 652838032Speter PORTABILITY FIXES: 652938032Speter AIX4: getpwnam() and getpwuid() do a sequential scan of the 653038032Speter /etc/security/passwd file when called as root. This 653138032Speter is very slow on some systems. To speed it up, use the 653238032Speter (undocumented) _getpw{nam,uid}_shadow() routines. 653338032Speter Patch from Chris Thomas of UCLA/OAC Systems Group. 653438032Speter SCO 5.x: include -lprot in the Makefile.

Problem 657338032Speter noted by Eric Bishop of Virginia Tech. 657438032Speter When doing text-based host canonification (typically /etc/hosts 657538032Speter lookup), a null host name would match any /etc/hosts entry 657638032Speter with space at the end of the line. Problem noted by Steve 657738032Speter Hubert of the University of Washington, Seattle. 657838032Speter 7 to 8 bit BASE64 MIME conversions could duplicate bits of text. 657938032Speter Problem reported by Tom Smith of Digital Equipment Corp. 658038032Speter Increase the size of the DNS answer buffer -- the standard UDP packet 658138032Speter size PACKETSZ (512) is not sufficient for some nameserver 658238032Speter answers containing very many resource records. The resolver 658338032Speter may also switch to TCP and retry if it detects UDP packet 658438032Speter overflow. Also, allow for the fact that the resolver 658538032Speter routines res_query and res_search return the size of the 658638032Speter *un*truncated answer in case the supplied answer buffer it 658738032Speter not big enough to accommodate the entire answer. Patch from 658838032Speter Eric Wassenaar. 658938032Speter Improvements to MaxDaemonChildren code. If you think you have too 659038032Speter many children, probe the ones you have to verify that they 659138032Speter are still around. Suggested by Jared Mauch of CICnet, Inc. 659238032Speter Also, do this probe before growing the vector of children 659338032Speter pids; this previously caused the vector to grow indefinitely 659438032Speter due to a race condition. Problem reported by Kyle Jones of 659538032Speter UUNET. 659638032Speter On some architectures, <db.h> (from the Berkeley DB library) defines 659738032Speter O_EXLOCK to zero; this fools the map compilation code into 659838032Speter thinking that it can avoid race conditions by locking on open. 659938032Speter Change it to check for O_EXLOCK non-zero. Problem noted by 660038032Speter Leif Erlingsson of Data Lege. 660138032Speter Always call res_init() on startup (if compiled in, of course) to 660238032Speter allow the sendmail.cf file to tweak resolver flags; without 660338032Speter it, flag tweaks in ResolverOptions are ignored. Patch from 660438032Speter Andrew Sun of Merrill Lynch. 660538032Speter Improvements to host status printing code. Suggested by Steve Hubert 660638032Speter of the University of Washington, Seattle. 660738032Speter Change MinQueueAge option processing to do the check for the job age 660838032Speter when reading the queue file, rather than at the end; this 660938032Speter avoids parsing the addresses, which can do DNS lookups. 661038032Speter Problem noted by John Beck of InReference, Inc. 661138032Speter When MIME was being 7->8 bit decoded, "From " lines weren't being 661238032Speter properly escaped. Problem noted by Peter Nilsson of the 661338032Speter University of Linkoping. 661438032Speter In some cases, sendmail would retain root permissions during queue 661538032Speter runs even if RunAsUser was set. Problem noted by Mark 661638032Speter Thomas of Mark G. Thomas Consulting. 661738032Speter If the F=l flag was set on an SMTP mailer to indicate that it is 661838032Speter actually local delivery, and NOTIFY=SUCCESS is specified in 661938032Speter the envelope, and the receiving SMTP server speaks DSN, then 662038032Speter the DSN would be both generated locally and propagated to the 662138032Speter other end. 662238032Speter The U= mailer field didn't correctly extract the group id if the 662338032Speter user id was numeric.

If this option is null (as 669738032Speter opposed to undefined) it can cause "null signature" syserrs 669838032Speter on illegal host names. 669938032Speter If a Base64 encoded text/plain message has no trailing newline in 670038032Speter the encoded text, conversion back to 8 bits will drop the 670138032Speter final line. Problem noted by Pierre David. 670238032Speter If running with a RunAsUser, sendmail would give bogus "cannot 670338032Speter setuid" (or seteuid, or setreuid) messages on some systems. 670438032Speter Problem pointed out by Jordan Mendelson of Web Services, Inc. 670538032Speter Always print error messages in -bv mode -- previously, -bv would 670638032Speter be absolutely silent on errors if the error mode was sent 670738032Speter to (say) mail-back. Problem noted by Kyle Jones of UUNET. 670838032Speter If -qI/R/S is set (or the ETRN command is used), ignore all long 670938032Speter term host status. This is necessary because it is common 671038032Speter to do this when you know a host has just come back up. 671138032Speter Disallow duplicate HELO/EHLO commands as required by RFC 1651 section 671238032Speter 4.2. Excessive permissiveness noted by Lee Flight of the 671338032Speter University of Leicester. 671438032Speter If a service (such as NIS) is specified as the last entry in the 671538032Speter service switch, but that service is not compiled in, sendmail 671638032Speter would return a temporary failure when an entry was not found 671738032Speter in the map. This caused the message to be queued instead of 671838032Speter bouncing immediately.

Pointed out by Munenari Hirayama of 675138032Speter NSC (Japan). 675238032Speter A message that didn't terminate with a newline would (sometimes) not 675338032Speter have the trailing "." added properly in the SMTP dialogue, 675438032Speter causing SMTP to hang. Patch from Per Hedeland of Ericsson. 675538032Speter The DaemonPortOptions suboption to bind to a particular address was 675638032Speter incorrect and nonfunctional due to a misunderstanding of the 675738032Speter semantics of binding on a passive socket.

In order to avoid 676238032Speter trashing memory, the buffer for all names has only been 676338032Speter slightly increased in size, to 12.8K from 10.2K -- this means 676438032Speter that if a single name had 100 MX records, the average size 676538032Speter of those records could not exceed 128 bytes.

Berkeley. 676938032Speter Print q_statdate and q_specificity in address structure debugging 677038032Speter printout. 677138032Speter Expand MCI structure flag bits for debugging output. 677238032Speter Support IPv6-style domain literals, which can have colons between 677338032Speter square braces. 677438032Speter Log open file descriptors for the "cannot dup" messages in deliver(); 677538032Speter this is an attempt to track down a bug that one person seems 677638032Speter to be having (it may be a Solaris bug!). 677738032Speter DSN NOTIFY parameters were not properly propagated across queue runs; 677838032Speter this caused the NOTIFY info to sometimes be lost. Problem 677938032Speter pointed out by Claus Assmann of the 678038032Speter Christian-Albrechts-University of Kiel. 678138032Speter The statistics gathered in the sendmail.st file were too high; in 678238032Speter some cases failures (e.g., user unknown or temporary failure) 678338032Speter would count as a delivery as far as the statistics were 678438032Speter concerned. Problem noted by Tom Moore of AT&T GIS. 678538032Speter Systems that don't have flock() would not send split envelopes in 678638032Speter the initial run. Problem pointed out by Leonard Zubkoff of 678738032Speter Dandelion Digital. 678838032Speter Move buffer overflow checking -- these primarily involve distrusting 678938032Speter results that may come from NIS and DNS. 679038032Speter 4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't 679138032Speter include <paths.h> and hence had the wrong pathnames for a few 679238032Speter things like /var/tmp. Reported by Matthew Green. 679338032Speter Conditions were reversed for the Priority: header, resulting in all 679438032Speter values being interpreted as non-urgent except for non-urgent, 679538032Speter which was interpreted as normal. Patch from Bryan Costales. 679638032Speter The -o (optional) flag was being ignored on hash and btree maps 679738032Speter since 8.7.2. Fix from Bryan Costales. 679838032Speter Content-Types listed in class "q" will always be encoded as 679938032Speter Quoted-Printable (or more accurately, will never be encoded 680038032Speter as base64). The class can have primary types (e.g., "text") 680138032Speter or full types (e.g., "text/plain"). Based on a suggestion by 680238032Speter Marius Olafsson of the University of Iceland. 680338032Speter Define ${envid} to be the original envelope id (from the ESMTP DSN 680438032Speter dialogue) so it can be passed to programs in mailers. 680538032Speter Define ${bodytype} to be the body type (from the -B flag or the 680638032Speter BODY= ESMTP parameter) so it can be passed to programs in 680738032Speter mailers. 680838032Speter Cause the VRFY command to return 252 instead of 250 unless the F=q 680938032Speter flag is set in the mailer descriptor. Suggested by John 681038032Speter Myers of CMU. 681138032Speter Implement ESMTP ETRN command to flush the queue for a specific host. 681238032Speter The command takes a host name; data for that host is 681338032Speter immediately (and asynchronously) flushed. Because this shares 681438032Speter the -qR implementation, other hosts may be attempted, but 681538032Speter there should be no security implications. Implementation 681638032Speter from John Beck of InReference, Inc. See RFC 1985 for details. 681738032Speter Add three new command line flags to pass in DSN parameters: -V envid 681838032Speter (equivalent to ENVID=envid on the MAIL command), -R ret 681938032Speter (equivalent to RET=ret on the MAIL command), and -Nnotify 682038032Speter (equivalent to NOTIFY=notify on the RCPT command). Note 682138032Speter that the -N flag applies to all recipients; there is no way 682238032Speter to specify per-address notifications on the command line, 682338032Speter nor is there an equivalent for the ORCPT= per-address 682438032Speter parameter. 682538032Speter Restore LogLevel option to be safe (it can only be increased); 682638032Speter apparently I went into paranoid mode between 8.6 and 8.7 682738032Speter and made it unsafe. Pointed out by Dabe Murphy of the 682838032Speter University of Maryland. 682938032Speter New logging on log level 15: all SMTP traffic. Patches from 683038032Speter Andrew Gross of San Diego Supercomputer Center. 683138032Speter NetInfo property value searching code wasn't stopping when it found 683238032Speter a match. This was causing the wrong values to be found (and 683338032Speter had a memory leak). Found by Bastian Schleuter of TU-Berlin. 683438032Speter Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed 683538032Speter out by Bill Wisner of Electronics for Imaging that you can't 683638032Speter use the bracket address form for the MAIL_HUB macro, since 683738032Speter that causes the brackets to remain in the envelope recipient 683838032Speter address used for delivery. The simple fix (stripping off the 683938032Speter brackets in the config file) breaks the use of IP literal 684038032Speter addresses. This flag will solve that problem. 684138032Speter Add MustQuoteChars option. This is a list of characters that must 684238032Speter be quoted if they are found in the phrase part of an address 684338032Speter (that is, the full name part). The characters @,;:\()[] are 684438032Speter always in this list and cannot be removed. The default is 684538032Speter this list plus . and ' to match RFC 822. 684638032Speter Add AllowBogusHELO option; if set, sendmail will allow HELO commands 684738032Speter that do not include a host name for back compatibility with 684838032Speter some stupid SMTP clients. Setting this violates RFC 1123 684938032Speter section 5.2.5. 685038032Speter Add MaxDaemonChildren option; if this is set, sendmail will start 685138032Speter rejecting connections if it has more than this many 685238032Speter outstanding children accepting mail. Note that you may 685338032Speter see more processes than this because of outgoing mail; this 685438032Speter is for incoming connections only. 685538032Speter Add ConnectionRateThrottle option. If set to a positive value, the 685638032Speter number of incoming SMTP connections that will be permitted 685738032Speter in a single second is limited to this number. Connections are 685838032Speter not refused during this time, just deferred. The intent is to 685938032Speter flatten out demand so that load average limiting can kick in. 686038032Speter It is less radical than MaxDaemonChildren, which will stop 686138032Speter accepting connections even if all the connections are idle 686238032Speter (e.g., due to connection caching). 686338032Speter Add Timeout.hoststatus option. This interval (defaulting to 30m) 686438032Speter specifies how long cached information about the state of a 686538032Speter host will be kept before they are considered stale and the 686638032Speter host is retried. If you are using persistent host status 686738032Speter (i.e., the HostStatusDirectory option is set) this will apply 686838032Speter between runs; otherwise, it applies only within a single queue 686938032Speter run and hence is useful only for hosts that have large queues 687038032Speter that take a very long time to run. 687138032Speter Add SingleLineFromHeader option. If set, From: headers are coerced 687238032Speter into being a single line even if they had newlines in them 687338032Speter when read. This is to get around a botch in Lotus Notes. 687438032Speter Text class maps were totally broken -- if you ever retrieved the last 687538032Speter item in a table it would be truncated. Problem noted by 687638032Speter Gregory Neil Shapiro of WPI. 687738032Speter Extend the lines printed by the mailq command (== the -bp flag) when 687838032Speter -v is given to 120 characters; this allows more information 687938032Speter to be displayed. Suggested by Gregory Neil Shapiro of WPI. 688038032Speter Allow macro definitions (`D' lines) with unquoted commas; previously 688138032Speter this was treated as end-of-input. Problem noted by Bryan 688238032Speter Costales. 688338032Speter The RET= envelope parameter (used for DSNs) wasn't properly written 688438032Speter to the queue file. Fix from John Hughes of Atlantic 688538032Speter Technologies, Inc. 688638032Speter Close /var/tmp/dead.letter after a successful write -- otherwise 688738032Speter if this happens in a queue run it can cause nasty delays. 688838032Speter Problem noted by Mark Horton of AT&T. 688938032Speter If userdb entries pointed to userdb entries, and there were multiple 689038032Speter values for a given key, the database cursor would get 689138032Speter trashed by the recursive call. Problem noted by Roy Mongiovi 689238032Speter of Georgia Tech. Fixed by reading all the values and creating 689338032Speter a comma-separated list; thus, the -v output will be somewhat 689438032Speter different for this case. 689538032Speter Fix buffer allocation problem with Hesiod-based userdb maps when 689638032Speter HES_GETMAILHOST is defined. Based on a patch by Betty Lee 689738032Speter of Stanford University. 689838032Speter When envelopes were split due to aliases with owner- aliases, and 689938032Speter there was some error on one of the lists, more than one of 690038032Speter the owners would get the message. Problem pointed out by 690138032Speter Roy Mongiovi of Georgia Tech. 690238032Speter Detect excessive recursion in macro expansions, e.g., $X defined 690338032Speter in terms of $Y which is defined in terms of $X. Problem 690438032Speter noted by Bryan Costales; patch from Eric Wassenaar. 690538032Speter When using F=U to get "ugly UUCP" From_ lines, a buffer could in 690638032Speter some cases get trashed causing bogus From_ lines. Fix from 690738032Speter Kyle Jones of UUNET. 690838032Speter When doing load average initialization, if the nlist call for avenrun 690938032Speter failed, the second and subsequent lookups wouldn't notice 691038032Speter that fact causing bogus load averages to be returned. Noted 691138032Speter by Casper Dik of Sun Holland. 691238032Speter Fix problem with incompatibility with some versions of inet_aton that 691338032Speter have changed the return value to unsigned, so a check for an 691438032Speter error return of -1 doesn't work. Use INADDR_NONE instead. 691538032Speter This could cause mail to addresses such as [foo.com] to bounce 691638032Speter or get dropped. Problem noted by Christophe Wolfhugel of the 691738032Speter Pasteur Institute. 691838032Speter DSNs were inconsistent if a failure occurred during the DATA phase 691938032Speter rather than the RCPT phase: the Action: would be correct, but 692038032Speter the detailed status information would be wrong. Problem noted 692138032Speter by Bob Snyder of General Electric Company. 692238032Speter Add -U command line flag and the XUSR ESMTP extension, both indicating 692338032Speter that this is the initial MUA->MTA submission. The flag current 692438032Speter does nothing, but in future releases (when MUAs start using 692538032Speter these flags) it will probably turn on things like DNS 692638032Speter canonification. 692738032Speter Default end-of-line string (E= specification on mailer [M] lines) 692838032Speter to \r\n on SMTP mailers. Default remains \n on non-SMTP 692938032Speter mailers. 693038032Speter Change the internal definition for the *file* and *include* mailers 693138032Speter to have $u in the argument vectors so that they aren't 693238032Speter misinterpreted as SMTP mailers and thus use \r\n line 693338032Speter termination. This will affect anyone who has redefined 693438032Speter either of these in their configuration file. 693538032Speter Don't assume that IDENT servers close the connection after a query; 693638032Speter responses can be newline terminated. From Terry Kennedy of 693738032Speter St. Peter's College. 693838032Speter Avoid core dumps on erroneous configuration files that have 693938032Speter $#mailer with nothing following. From Bryan Costales. 694038032Speter Avoid null pointer dereference with high debug values in unlockqueue. 694138032Speter Fix from Randy Martin of Clemson University. 694238032Speter Fix possible buffer overrun when expanding very large macros. Fix 694338032Speter from Kyle Jones of UUNET. 694438032Speter After 25 EXPN or VRFY commands, start pausing for a second before 694538032Speter processing each one. This avoids a certain form of denial 694638032Speter of service attack. Potential attack pointed out by Bryan 694738032Speter Costales. 694838032Speter Allow new named (not numbered!) config file rules to do validity 694938032Speter checking on SMTP arguments: check_mail for MAIL commands and 695038032Speter check_rcpt for RCPT commands. These rulesets can do anything 695138032Speter they want; their result is ignored unless they resolve to the 695238032Speter $#error mailer, in which case the indicated message is printed 695338032Speter and the command is rejected. Similarly, the check_compat 695438032Speter ruleset is called before delivery with "from_addr $| to_addr" 695538032Speter (the $| is a meta-symbol used to separate the two addresses); 695638032Speter it can give a "this sender can't send to this recipient" 695738032Speter notification. Note that this patch allows $| to stand alone 695838032Speter in rulesets. 695938032Speter Define new macros ${client_name}, ${client_addr}, and ${client_port} 696038032Speter that have the name, IP address, and port number (respectively) 696138032Speter of the SMTP client (that is, the entity at the other end of 696238032Speter the connection. These can be used in (e.g.) check_rcpt to 696338032Speter verify that someone isn't trying to relay mail through your 696438032Speter host inappropriately. Be sure to use the deferred evaluation 696538032Speter form, for example $&{client_name}, to avoid having these bound 696638032Speter when sendmail reads the configuration file. 696738032Speter Add new config file rule check_relay to check the incoming connection 696838032Speter information. Like check_compat, it is passed the host name 696938032Speter and host address separated by $| and can reject connections 697038032Speter on that basis. 697138032Speter Allow IDA-style recursive function calls. Code contributed by Mark 697238032Speter Lovell and Paul Vixie. 697338032Speter Eliminate the "No ! in UUCP From address!" message" -- instead, create 697438032Speter a virtual UUCP address using either a domain address or the $k 697538032Speter macro. Based on code contributed by Mark Lovell and Paul 697638032Speter Vixie. 697738032Speter Add Stanford LDAP map. Requires special libraries that are not 697838032Speter included with sendmail. Contributed by Booker C. Bense 697938032Speter <bbense@networking.stanford.edu>; contact him for support. 698038032Speter See also the src/READ_ME file. 698138032Speter Allow -dANSI to turn on ANSI escape sequences in debug output; this 698238032Speter puts metasymbols (e.g., $+) in reverse video. Really useful 698338032Speter only for debugging deep bits of code where it is important to 698438032Speter distinguish between the single-character metasymbol $+ and the 698538032Speter two characters $, +. 698638032Speter Changed ruleset 89 (executed in dumpstate()) to a named ruleset, 698738032Speter debug_dumpstate. 698838032Speter Add new UnsafeGroupWrites option; if set, .forward and :include: 698938032Speter files that are group writable are considered "unsafe" -- that 699038032Speter is, programs and files referenced from such files are not 699138032Speter valid recipients. 699238032Speter Delete bogosity test for FallBackMX host; this prevented it to be a 699338032Speter name that was not in DNS or was a domain-literal. Problem 699438032Speter noted by Tom May. 699538032Speter Change the introduction to error messages to more clearly delineate 699638032Speter permanent from temporary failures; if both existed in a 699738032Speter single message it could be confusing. Suggested by John 699838032Speter Beck of InReference, Inc. 699938032Speter The IngoreDot (i) option didn't work for lines that were terminated 700038032Speter with CRLF. Problem noted by Ted Stockwell of Secure 700138032Speter Computing Corporation. 700238032Speter Add a heuristic to improve the handling of unbalanced `<' signs in 700338032Speter message headers. Problem reported by Matt Dillon of Best 700438032Speter Internet Communications. 700538032Speter Check for bogus characters in the 0200-0237 range; since these are 700638032Speter used internally, very strange errors can occur if those 700738032Speter characters appear in headers. Problem noted by Anders Gertz 700838032Speter of Lysator. 700938032Speter Implement 7 -> 8 bit MIME conversions. This only takes place if the 701038032Speter recipient mailer has the F=9 flag set, and only works on 701138032Speter text/plain body types. Code contributed by Marius Olafsson 701238032Speter of the University of Iceland. 701338032Speter Special case "postmaster" name so that it is always treated as lower 701438032Speter case in alias files regardless of configuration settings; 701538032Speter this prevents some potential problems where "Postmaster" or 701638032Speter "POSTMASTER" might not match "postmaster". In most cases 701738032Speter this change is a no-op. 701838032Speter The -o map flag was ignored for text maps. Problem noted by Bryan 701938032Speter Costales. 702038032Speter The -a map flag was ignored for dequote maps. Problem noted by 702138032Speter Bryan Costales. 702238032Speter Fix core dump when a lookup of a class "prog" map returns no 702338032Speter response. Patch from Bryan Costales. 702438032Speter Log instances where sendmail is deferring or rejecting connections 702538032Speter on LogLevel 14. Suggested by Kyle Jones of UUNET. 702638032Speter Include port number in process title for network daemons. Suggested 702738032Speter by Kyle Jones of UUNET. 702838032Speter Send ``double bounces'' (errors that occur when sending an error 702938032Speter message) to the address indicated in the DoubleBounceAddress 703038032Speter option (default: postmaster). Previously they were always 703138032Speter sent to postmaster. Suggested by Kyle Jones of UUNET. 703238032Speter Add new mode, -bD, that acts like -bd in all respects except that 703338032Speter it runs in foreground. This is useful for using with a 703438032Speter wrapper that "watches" system services. Suggested by Kyle 703538032Speter Jones of UUNET. 703638032Speter Fix botch in spacing around (parenthesized) comments in addresses 703738032Speter when the comment comes before the address. Patch from 703838032Speter Motonori Nakamura of Kyoto University. 703938032Speter Use the prefix "Postmaster notify" on the Subject: lines of messages 704038032Speter that are being bounced to postmaster, rather than "Returned 704138032Speter mail". This permits the person who is postmaster more 704238032Speter easily determine what messages are to their role as 704338032Speter postmaster versus bounces to mail they actually sent. Based 704438032Speter on a suggestion by Motonori Nakamura. 704538032Speter Add new value "time" for QueueSortOrder option; this causes the queue 704638032Speter to be sorted strictly by the time of submission. Note that 704743730Speter this can cause very bad behavior over slow lines (because 704838032Speter large jobs will tend to delay small jobs) and on nodes with 704938032Speter heavy traffic (because old things in the queue for hosts that 705038032Speter are down delay processing of new jobs). Also, this does not 705138032Speter guarantee that jobs will be delivered in submission order 705238032Speter unless you also set DeliveryMode=queue. In general, it should 705338032Speter probably only be used on the command line, and only in 705438032Speter conjunction with -qRhost.domain. In fact, there are very few 705538032Speter cases where it should be used at all. Based on an 705638032Speter implementation by Motonori Nakamura. 705738032Speter If a map lookup in ruleset 5 returns tempfail, queue the message in 705838032Speter the same manner as other rulesets. Previously a temporary 705938032Speter failure in ruleset 5 was ignored. Patch from Booker Bense 706038032Speter of Stanford University. 706138032Speter Don't proceed to the next MX host if an SMTP MAIL command returns a 706238032Speter 5yz (permanent failure) code. The next MX host will still be 706338032Speter tried if the connection cannot be opened in the first place 706438032Speter or if the MAIL command returns a 4yz (temporary failure) code. 706538032Speter (It's hard to know what to do here, since neither RFC 974 nor 706638032Speter RFC 1123 specify when to proceed to the next MX host.) 706738032Speter Suggested by Jonathan Kamens of OpenVision, Inc. 706838032Speter Add new "-t" flag for map definitions (the "K" line in the .cf file). 706938032Speter This causes map lookups that get a temporary failure (e.g., 707038032Speter name server failure) to _not_ defer the delivery of the 707138032Speter message. This should only be used if your configuration file 707238032Speter is prepared to do something sensible in this case. Based on 707338032Speter an idea by Gregory Shapiro of WPI. 707438032Speter Fix problem finding network interface addresses. Patch from 707538032Speter Motonori Nakamura. 707638032Speter Don't reject qf entries that are not owned by your effective uid if 707790792Sgshapiro you are not running set-user-ID; this makes management of 707880785Sgshapiro certain kinds of firewall setups difficult. Patch 707980785Sgshapiro suggested by Eamonn Coleman of Qualcomm. 708038032Speter Add persistent host status. This keeps the information normally 708138032Speter maintained within a single queue run in disk files that are 708238032Speter shared between sendmail instances. The HostStatusDirectory 708338032Speter is the directory in which the information is maintained. If 708438032Speter not set, persistent host status is turned off. If not a full 708538032Speter pathname, it is relative to the queue directory. A common 708638032Speter value is ".hoststat". 708738032Speter There are also two new operation modes: 708838032Speter * -bh prints the status of hosts that have had recent 708938032Speter connections. 709038032Speter * -bH purges the host statuses. No attempt is made to save 709138032Speter recent status information. 709238032Speter This feature was originally written by Paul Vixie of Vixie 709338032Speter Enterprises for KJS and adapted for V8 by Mark Lovell of 709438032Speter Bigrock Consulting. Paul's funding of Mark and Mark's patience 709538032Speter with my insistence that things fit cleanly into the V8 709638032Speter framework is gratefully appreciated. 709738032Speter New SingleThreadDelivery option (requires HostStatusDirectory to 709838032Speter operate). Avoids letting two sendmails on the local machine 709964562Sgshapiro open connections to the same remote host at the same time. 710038032Speter This reduces load on the other machine, but can cause mail to 710138032Speter be delayed (for example, if one sendmail is delivering a huge 710238032Speter message, other sendmails won't be able to send even small 710338032Speter messages). Also, it requires another file descriptor (for the 710438032Speter lock file) per connection, so you may have to reduce 710538032Speter ConnectionCacheSize to avoid running out of per-process 710638032Speter file descriptors. Based on the persistent host status code 710738032Speter contributed by Paul Vixie and Mark Lovell. 710838032Speter Allow sending to non-simple files (e.g., /dev/null) even if the 710938032Speter SafeFileEnvironment option is set. Problem noted by Bryan 711038032Speter Costales. 711138032Speter The -qR flag mistakenly matched flags in the "R" line of the queue 711238032Speter file. Problem noted by Bryan Costales. 711338032Speter If a job was aborted using the interrupt signal (e.g., control-C from 711438032Speter the keyboard), on some occasions an empty df file would be 711538032Speter left around; these would collect in the queue directory. 711638032Speter Problem noted by Bryan Costales. 711738032Speter Change the makesendmail script to enhance the search for Makefiles 711838032Speter based on release number. For example, on SunOS 5.5.1, it will 711938032Speter search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then 712038032Speter Makefile.SunOS.5.x (in addition to the other rules, e.g., 712138032Speter adding $arch). Problem noted by Jason Mastaler of Atlanta 712238032Speter Webmasters. 712338032Speter When creating maps using "newaliases", always map the keys to lower 712438032Speter case when creating the map unless the -f flag is specified on 712538032Speter the map itself. Previously this was done based on the F=u 712638032Speter flag in the local mailer, which meant you could create aliases 712738032Speter that you could never access. Problem noted by Bob Wu of DEC. 712838032Speter When a job was read from the queue, the bits causing notification on 712938032Speter failure or delay were always set. This caused those 713038032Speter notifications to be sent even if NOTIFY=NEVER had been 713138032Speter specified. Problem noted by Steve Hubert of the University 713238032Speter of Washington, Seattle. 713338032Speter Add new configurable routine validate_connection (in conf.c). This 713438032Speter lets you decide if you are willing to accept traffic from 713538032Speter this host. If it returns FALSE, all SMTP commands will return 713638032Speter "550 Access denied". -DTCPWRAPPERS will include support for 713738032Speter TCP wrappers; you will need to add -lwrap to the link line. 713838032Speter (See src/READ_ME for details.) 713938032Speter Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster 714038032Speter bounces. Some people seemed to think that this could be 714138032Speter confusing (even though it is true). Suggested by Motonori 714238032Speter Nakamura. 714338032Speter Add new RunAsUser option; this causes sendmail to do a setuid to that 714438032Speter user early in processing to avoid potential security problems. 714538032Speter However, this means that all .forward and :include: files must 714638032Speter be readable by that user, and all files to be written must be 714738032Speter writable by that user and all programs will be executed by that 714838032Speter user. It is also incompatible with the SafeFileEnvironment 714938032Speter option. In other words, it may not actually add much to 715038032Speter security. However, it should be useful on firewalls and other 715138032Speter places where users don't have accounts and the aliases file is 715238032Speter well constrained. 715338032Speter Add Timeout.iconnect. This is like Timeout.connect except it is used 715438032Speter only on the first attempt to delivery to an address. It could 715538032Speter be set to be lower than Timeout.connect on the principle that 715638032Speter the mail should go through quickly to responsive hosts; less 715738032Speter responsive hosts get to wait for the next queue run. 715838032Speter Fix a problem on Solaris that occasionally causes programs 715938032Speter (such as vacation) to hang with their standard input connected 716038032Speter to a UDP port. It also created some signal handling problems. 716138032Speter The problems turned out to be an interaction between vfork(2) 716238032Speter and some of the libraries, particularly NIS/NIS+. I am 716338032Speter indebted to Tor Egge <tegge@idt.ntnu.no> for this fix. 716438032Speter Change user class map to do the same matching that actual delivery 716538032Speter will do instead of just a /etc/passwd lookup. This adds 716638032Speter fuzzy matching to the user map. Patch from Dan Oscarsson. 716738032Speter The Timeout.* options are not safe -- they can be used to create a 716838032Speter denial-of-service attack. Problem noted by Christophe 716938032Speter Wolfhugel. 717043730Speter Don't send PostmasterCopy messages in the event of a "delayed" 717138032Speter notification. Suggested by Barry Bouwsma. 717238032Speter Don't advertise "VERB" ESMTP extension if the "noexpn" privacy 717338032Speter option is set, since this disables VERB mode. Suggested 717438032Speter by John Hawkinson of MIT. 717538032Speter Complain if the QueueDirectory (Q) option is not set. Problem noted 717638032Speter by Motonori Nakamura of Kyoto University. 717738032Speter Only queue messages on transient .forward open failures if there 717843730Speter were no successful opens. The previous behavior caused it 717938032Speter to queue even if a "fall back" .forward was found. Problem 718038032Speter noted by Ann-Kian Yeo of the Dept. of Information Systems 718138032Speter and Computer Science (DISCS), NUS, Singapore. 718238032Speter Don't do 8->7 bit conversions when bouncing a MIME message that 718338032Speter is bouncing because of a MIME error during 8->7 bit conversion; 718438032Speter the encapsulated message will bounce again, causing a loop. 718538032Speter Problem noted by Steve Hubert of the University of Washington. 718638032Speter Create xf (transcript) files using the TempFileMode option value 718738032Speter instead of 0644. Suggested by Ann-Kian Yeo of the 718838032Speter National University of Singapore. 718938032Speter Print errors if setgid/setuid/etc. fail during delivery. This helps 719038032Speter detect cases where DefaultUid is set to something that the 719138032Speter system can't cope with. 719238032Speter PORTABILITY FIXES: 719338032Speter Support for AIX/RS 2.2.1 from Mark Whetzel of Western 719438032Speter Atlas International. 719538032Speter Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell 719638032Speter <bicknell@ufp.org>. 719738032Speter On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only 719838032Speter work on the first recipient of a message due to a 719938032Speter bug in the getpwent family.

Based on a patch from Randall 724238032Speter Winchester of the University of Maryland. 724338032Speter CONFIG: add generic-nextstep3.3.mc file. Contributed by 724438032Speter Robert La Ferla of Hot Software. 724538032Speter CONFIG: allow mailertables to resolve to ``error:code message'' 724638032Speter (where "code" is an exit status) on domains (previously 724738032Speter worked only on hosts). Patch from Cor Bosman of Xs4all 724838032Speter Foundation. 724938032Speter CONFIG: hooks for IPv6-style domain literals. 725038032Speter CONFIG: predefine ALIAS_FILE and change the prototype file so that 725138032Speter if it is undefined the AliasFile option is never set; this 725238032Speter should be transparent for most everyone. Suggested by John 725338032Speter Myers of CMU. 725438032Speter CONFIG: add FEATURE(limited_masquerade). Without this feature, any 725538032Speter domain listed in $=w is masqueraded. With it, only those 725638032Speter domains listed in a MASQUERADE_DOMAIN macro are masqueraded. 725738032Speter CONFIG: add FEATURE(masquerade_entire_domain). This causes 725838032Speter masquerading specified by MASQUERADE_DOMAIN to apply to all 725938032Speter hosts under those domains as well as the domain headers 726038032Speter themselves. For example, if a configuration had 726138032Speter MASQUERADE_DOMAIN(foo.com), then without this feature only 726238032Speter foo.com would be masqueraded; with it, *.foo.com would be 726338032Speter masqueraded as well. Based on an implementation by Richard 726438032Speter (Pug) Bainter of U. Texas. 726538032Speter CONFIG: add FEATURE(genericstable) to do a more general rewriting of 726638032Speter outgoing addresses. Defaults to ``hash -o /etc/genericstable''. 726738032Speter Keys are user names; values are outgoing mail addresses. Yes, 726838032Speter this does overlap with the user database, and figuring out 726938032Speter just when to use which one may be tricky. Based on code 727038032Speter contributed by Richard (Pug) Bainter of U. Texas with updates 727138032Speter from Per Hedeland of Ericsson. 727238032Speter CONFIG: add FEATURE(virtusertable) to do generalized rewriting of 727338032Speter incoming addresses. Defaults to ``hash -o /etc/virtusertable''. 727438032Speter Keys are either fully qualified addresses or just the host 727538032Speter part (with the @ sign). For example, a table containing: 727638032Speter info@foo.com foo-info 727738032Speter info@bar.com bar-info 727838032Speter @baz.org jane@elsewhere.net 727938032Speter would send all mail destined for info@foo.com to foo-info 728038032Speter (which is presumably an alias), mail addressed to info@bar.com 728138032Speter to bar-info, and anything addressed to anyone at baz.org will 728238032Speter be sent to jane@elsewhere.net. The names foo.com, bar.com, 728338032Speter and baz.org must all be in $=w. Based on discussions with 728438032Speter a great many people. 728538032Speter CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS. 728638032Speter Suggested by Richard Bainter. 728738032Speter CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the 728838032Speter "fax" mailer. 728938032Speter CONFIG: allow mailertable entries to resolve to local:user; this 729038032Speter passes the original user@host in to procmail-style local 729138032Speter mailers as the "detail" information to allow them to do 729238032Speter additional clever processing. From Joe Pruett of 729338032Speter Teleport Corporation. Delivery to the original user can 729438032Speter be done by specifying "local:" (with nothing after the colon). 729538032Speter CONFIG: allow any context that takes "mailer:domain" to also take 729638032Speter "mailer:user@domain" to force mailing to the given user; 729738032Speter "local:user" can also be used to do local delivery. This 729838032Speter applies on *_RELAY and in the mailertable entries. Based 729938032Speter on a suggestion by Ribert Kiessling of Easynet. 730038032Speter CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that 730138032Speter limits the possible domains; this reduces the number of DNS 730238032Speter lookups required to support this feature. For example, 730338032Speter FEATURE(bestmx_is_local, my.site.com) limits the lookups 730438032Speter to domains under my.site.com. Code contributed by Anthony 730538032Speter Thyssen <anthony@cit.gu.edu.au>. 730638032Speter CONFIG: LOCAL_RULESETS introduces any locally defined rulesets, 730738032Speter such as the check_rcpt ruleset. Suggested by Gregory Shapiro 730838032Speter of WPI. 730938032Speter CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the 731038032Speter event you have to define local mailers. Suggested by 731138032Speter Gregory Shapiro of WPI. 731238032Speter CONFIG: fix cases where a three- (or more-) stage route-addr could 731338032Speter be misinterpreted as a list:...; syntax. Based on a patch by 731438032Speter Vlado Potisk <Vlado_Potisk@tempest.sk>. 731538032Speter CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is 731638032Speter remotely connected. The address host!user was being 731738032Speter converted to host!user@thishost instead of host!user@uurelay. 731838032Speter Problem noted by William Gianopoulos of Raytheon Company. 731938032Speter CONFIG: add confTO_ICONNECT to set Timeout.iconnect. 732038032Speter CONFIG: change FEATURE(redirect) message from "User not local" to 732138032Speter "User has moved"; the former wording was confusing if the 732238032Speter new address is still on the local host. Based on a suggestion 732338032Speter by Andreas Luik. 732438032Speter CONFIG: add support in FEATURE(nullclient) for $=E (exposed users). 732538032Speter However, the class is not pre-initialized to contain root. 732638032Speter Suggested by Gregory Neil Shapiro. 732738032Speter CONTRIB: Remove XLA code at the request of the author, Christophe 732838032Speter Wolfhugel. 732938032Speter CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm. 733038032Speter MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note 733138032Speter well: this produces a slightly different mailbox format (no 733238032Speter Content-Length: headers), file ownerships and modes are 733338032Speter different (not owned by group mail; mode 600 instead of 660), 733438032Speter and the local mailer flags will have to be tweaked (make them 733538032Speter match bsd4.4) in order to use this mailer. Patches from Paul 733638032Speter Hammann of the Missouri Research and Education Network. 733738032Speter MAIL.LOCAL: in some cases it could return EX_OK even though there 733838032Speter was a delivery error, such as if the ownership on the file 733938032Speter was wrong or the mode changed between the initial stat and 734038032Speter the open.

They were not 742638032Speter properly repaired in 8.7.1. 742738032Speter Completely delete the Bcc: header if and only if there are other 742838032Speter valid recipient headers (To:, Cc: or Apparently-To:, the 742938032Speter last being a historic botch, of course). If Bcc: is the 743038032Speter only recipient header in the message, its value is tossed, 743143730Speter but the header name is kept. The old behavior (always keep 743238032Speter the header name and toss the value) allowed primary recipients 743338032Speter to see that a Bcc: went to _someone_. 743438032Speter Include queue id on ``Authentication-Warning: <host>: <user> set 743538032Speter sender to <address> using -f'' syslog messages. Suggested 743638032Speter by Kari Hurtta. 743738032Speter If a sequence or switch map lookup entry gets a tempfail but then 743838032Speter continues on to another map type, but the name is not found, 743938032Speter return a temporary failure from the sequence or switch map. 744038032Speter For example, if hosts search ``dns files'' and DNS fails 744138032Speter with a tempfail, the hosts map will go on and search files, 744238032Speter but if it fails the whole thing should be a tempfail, not 744338032Speter a permanent (host unknown) failure, even though that is the 744438032Speter failure in the hosts.files map. This error caused hard 744538032Speter bounces when it should have requeued. 744638032Speter Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo 744790792Sgshapiro owned by bar mode 700 and inbox being set-user-ID bar stopped 744838032Speter working properly due to excessive paranoia. Pointed out by 744938032Speter John Hawkinson of Panix. 745038032Speter An SMTP RCPT command referencing a host that gave a nameserver 745138032Speter timeout would return a 451 command (8.6 accepted it and 745243730Speter queued it locally). Revert to the 8.6 behavior in order 745338032Speter to simplify queue management for clustered systems. Suggested 745438032Speter by Gregory Neil Shapiro of WPI. The same problem could break 745538032Speter MH, which assumes that the SMTP session will succeed (tsk, tsk 745638032Speter -- mail gets lost!); this was pointed out by Stuart Pook of 745738032Speter Infobiogen. 745838032Speter Fix possible buffer overflow in munchstring(). This was not a security 745938032Speter problem because you couldn't specify any argument to this 746038032Speter without first giving up root privileges, but it is still a 746138032Speter good idea to avoid future problems.

Pointed out by Allan Johannesen of WPI. 748038032Speter Config files that had no AliasFile definition were defaulting to 748138032Speter using /etc/aliases; this caused problems with nullclient 748238032Speter configurations.

Fix from Brian Coan of the 751438032Speter Association for Progressive Communications. 751538032Speter If MinQueueAge was set and a message was considered but not run 751638032Speter during a queue run and the Timeout.queuereturn interval was 751738032Speter reached, a "timed out" error message would be returned that 751838032Speter didn't include the failed address (and claimed to be a warning 751938032Speter even though it was fatal). The fix is to not return such 752038032Speter messages until they are actually tried, i.e., in the next 752138032Speter MinQueueAge interval.

From Tom Moore of AT&T GIS. 757838032Speter Shorten parameters passed to syslog() in some contexts to avoid a 757938032Speter bug in many vendors' implementations of that routine. Although 758038032Speter this isn't really a bug in sendmail per se, and my solution 758138032Speter has to assume that syslog() has at least a 1K buffer size 758238032Speter internally (I know some vendors have shortened this 758338032Speter dramatically -- they're on their own), sendmail is a popular 758438032Speter target. Also, limit the size of %s arguments in sprintf. 758538032Speter These both have possible security implications. Solutions 758638032Speter suggested by Casper Dik of Sun's Network Security Group 758738032Speter (Holland), Mark Seiden, and others. 758838032Speter Fix a problem that might cause a non-standard -B (body type) 758938032Speter parameter to be passed to the next server with undefined 759038032Speter results.

Robert 759838032Speter Elz. 759938032Speter Avoid some possible null pointer dereferences. Fixes from Randy 760038032Speter Martin <WOLF@CLEMSON.EDU> 760138032Speter When sendmail starts up on systems that have no fully qualified 760238032Speter domain name (FQDN) anywhere in the first matching host map 760338032Speter (e.g., /etc/hosts if the hosts service searches "files dns"), 760438032Speter sendmail would sleep to try to find a FQDN, which it really 760538032Speter really needs. This has been changed to fall through to the 760638032Speter next map type if it can't find a FQDN -- i.e., if the hosts 760738032Speter file doesn't have a FQDN, it will try dns even though the 760838032Speter short name was found in /etc/hosts. This is probably a crock, 760938032Speter but many people have hosts files without FQDNs. Remember: 761038032Speter domain names are your friends. 761138032Speter Log a high-priority message if you can't find your FQDN during startup. 761238032Speter Suggested by Simon Barnes of Schlumberger Limited. 761338032Speter When using Hesiod, initialize it early to improve error reporting. 761438032Speter Patch from Don Lewis of Silicon Systems, Inc. 761538032Speter Apparently at least some versions of Linux have a 90 !minute!

This can 773838032Speter result in an extra 60 second delay on startup if your system 773938032Speter hostname (as returned by hostname(1)) has no dot and no names 774038032Speter listed in /etc/hosts or your NIS map have a dot. 774138032Speter Check for proper domain name on HELO and EHLO commands per 774238032Speter RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III 774338032Speter of Michigan Technological University. 774438032Speter Relax chownsafe rules slightly -- old version said that if you 774538032Speter can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, 774638032Speter if fpathconf returned EINVAL or ENOSYS), assume that 774738032Speter chown is not safe. The new version falls back to whether 774838032Speter you are on a BSD system or not. This is important for 774938032Speter SunOS, which apparently always returns one of those 775038032Speter error codes. This impacts whether you can mail to files 775138032Speter or not. 775238032Speter Syntax errors such as unbalanced parentheses in the configuration 775338032Speter file could be omitted if you had "Oem" prior to the 775438032Speter syntax error in the config file. Change to always print 775538032Speter the error message. It was especially weird because it 775638032Speter would cause a "warning" message to be sent to the Postmaster 775738032Speter for every message sent (but with no transcript). Problem 775838032Speter noted by Gregory Paris of Motorola. 775938032Speter Rewrite collect and putbody to handle full 8-bit data, including 776038032Speter zero bytes. These changes are internally extensive, but 776138032Speter should have minimal impact on external function. 776238032Speter Allow full words for option names -- if the option letter is 776338032Speter (apparently) a space, then take the word following -- e.g., 776438032Speter O MatchGECOS=TRUE 776538032Speter The full list of old and new names is as follows: 776638032Speter 7 SevenBitInput 776738032Speter 8 EightBitMode 776838032Speter A AliasFile 776938032Speter a AliasWait 777038032Speter B BlankSub 777138032Speter b MinFreeBlocks/MaxMessageSize 777238032Speter C CheckpointInterval 777338032Speter c HoldExpensive 777438032Speter D AutoRebuildAliases 777538032Speter d DeliveryMode 777638032Speter E ErrorHeader 777738032Speter e ErrorMode 777838032Speter f SaveFromLine 777938032Speter F TempFileMode 778038032Speter G MatchGECOS 778138032Speter H HelpFile 778238032Speter h MaxHopCount 778338032Speter i IgnoreDots 778438032Speter I ResolverOptions 778538032Speter J ForwardPath 778638032Speter j SendMimeErrors 778738032Speter k ConnectionCacheSize 778838032Speter K ConnectionCacheTimeout 778938032Speter L LogLevel 779038032Speter l UseErrorsTo 779138032Speter m MeToo 779238032Speter n CheckAliases 779338032Speter O DaemonPortOptions 779438032Speter o OldStyleHeaders 779538032Speter P PostmasterCopy 779638032Speter p PrivacyOptions 779738032Speter Q QueueDirectory 779838032Speter q QueueFactor 779938032Speter R DontPruneRoutes 780038032Speter r, T Timeout 780138032Speter S StatusFile 780238032Speter s SuperSafe 780338032Speter t TimeZoneSpec 780438032Speter u DefaultUser 780538032Speter U UserDatabaseSpec 780643730Speter V FallbackMXHost 780738032Speter v Verbose 780838032Speter w TryNullMXList 780938032Speter x QueueLA 781038032Speter X RefuseLA 781138032Speter Y ForkEachJob 781238032Speter y RecipientFactor 781338032Speter z ClassFactor 781438032Speter Z RetryFactor 781538032Speter The old macros that passed information into sendmail have 781638032Speter been changed to options; those correspondences are: 781738032Speter $e SmtpGreetingMessage 781838032Speter $l UnixFromLine 781938032Speter $o OperatorChars 782038032Speter $q (deleted -- not necessary) 782138032Speter To avoid possible problems with an older sendmail, 782238032Speter configuration level 6 is accepted by this version of 782338032Speter sendmail; any config file using the new names should 782438032Speter specify "V6" in the configuration. 782538032Speter Change address parsing to properly note that a phrase before a 782638032Speter colon and a trailing semicolon are essentially the same 782738032Speter as text outside of angle brackets (i.e., sendmail should 782838032Speter treat them as comments). This is to handle the 782938032Speter ``group name: addr1, addr2, ..., addrN;'' syntax (it will 783038032Speter assume that ``group name:'' is a comment on the first 783138032Speter address and the ``;'' is a comment on the last address). 783238032Speter This requires config file support to get right. It does 783338032Speter understand that :: is NOT this syntax, and can be turned 783438032Speter off completely by setting the ColonOkInAddresses option. 783538032Speter Level 6 config files added with new mailer flags: 783638032Speter A Addresses are aliasable. 783738032Speter i Do udb rewriting on envelope as well as header 783838032Speter sender lines. Applies to the from address mailer 783938032Speter flags rather than the recipient mailer flags. 784038032Speter j Do udb rewriting on header recipient addresses. 784138032Speter Applies to the sender mailer flags rather than the 784238032Speter recipient mailer flags. 784338032Speter k Disable check for loops when doing HELO command. 784438032Speter o Always run as the mail recipient, even on local 784538032Speter delivery. 784638032Speter w Check for an /etc/passwd entry for this user. 784738032Speter 5 Pass addresses through ruleset 5. 784838032Speter : Check for :include: on this address. 784938032Speter | Check for |program on this address. 785038032Speter / Check for /file on this address. 785138032Speter @ Look up sender header addresses in the user 785238032Speter database. Applies to the mailer flags for the 785338032Speter mailer corresponding to the envelope sender 785438032Speter address, rather than to recipient mailer flags. 785538032Speter Pre-level 6 configuration files set A, w, 5, :, |, /, and @ 785638032Speter on the "local" mailer, the o flag on the "prog" and "*file*" 785738032Speter mailers, and the ColonOkInAddresses option. 785838032Speter Eight-to-seven bit MIME conversions. This borrows ideas from 785938032Speter John Beck of Hewlett-Packard, who generously contributed 786038032Speter their implementation to me, which I then didn't use (see 786138032Speter mime.c for an explanation of why). This adds the 786238032Speter EightBitMode option (a.k.a. `8') and an F=8 mailer flag 786338032Speter to control handling of 8-bit data. These have to cope with 786438032Speter two types of 8-bit data: unlabelled 8-bit data (that is, 786538032Speter 8-bit data that is entered without declaring it as 8-bit 786638032Speter MIME -- technically this is illegal according to the 786738032Speter specs) and labelled 8-bit data (that is, it was declared 786838032Speter as 8BITMIME in the ESMTP session or by using the 786938032Speter -B8BITMIME command line flag). If the F=8 mailer flag is 787038032Speter set then 8-bit data is sent to non-8BITMIME machines 787138032Speter instead of converting to 7 bit (essentially using 787238032Speter just-send-8 semantics). The values for EightBitMode are: 787338032Speter m convert unlabelled 8-bit input to 8BITMIME, and do 787438032Speter any necessary conversion of 8BITMIME to 7BIT 787538032Speter (essentially, the full MIME option). 787638032Speter p pass unlabelled 8-bit input, but convert labelled 787738032Speter 8BITMIME input to 7BIT as required (default). 787838032Speter s strict adherence: reject unlabelled 8-bit input, 787938032Speter convert 8BITMIME to 7BIT as required. The F=8 788038032Speter flag is ignored. 788138032Speter Unlabelled 8-bit data is rejected in mode `s' regardless of 788238032Speter the setting of F=8. 788338032Speter Add new internal class 'n', which is the set of MIME Content-Types 788438032Speter which can not be 8 to 7 bit encoded because of other 788538032Speter considerations. Types "multipart/*" and "message/*" are 788638032Speter never directly encoded (although their components can be). 788738032Speter Add new internal class 's', which is the set of subtypes of the 788838032Speter MIME message/* content type that can be treated as though 788938032Speter they are an RFC822 message. It is predefined to have 789038032Speter "rfc822". Suggested By Kari Hurtta. 789138032Speter Add new internal class 'e'. This is the set of MIME 789238032Speter Content-Transfer-Encodings that can be converted to 789338032Speter a seven bit format (Quoted-Printable or Base64). It is 789438032Speter preinitialized to contain "7bit", "8bit", and "binary". 789538032Speter Add C=charset mailer parameter and the the DefaultCharSet option (no 789638032Speter short name) to set the default character set to use in the 789738032Speter Content-Type: header when doing encoding of an 8-bit message 789838032Speter which isn't marked as MIME into MIME format. If the C= 789938032Speter parameter is set on the Envelope From address, use that as 790038032Speter the default encoding; else use the DefaultCharSet option. 790138032Speter If neither is set, it defaults to "unknown-8bit" as 790238032Speter suggested by RFC 1428 section 3. 790338032Speter Allow ``U=user:group'' field in mailer definition to set a default 790438032Speter user and group that a mailer will be executed as. This 790538032Speter overrides the 'u' and 'g' options, and if the `F=S' flag is 790638032Speter also set, it is the uid/gid that will always be used (that 790738032Speter is, the controlling address is ignored). The values may be 790838032Speter numeric or symbolic; if only a symbolic user is given (no 790938032Speter group) that user's default group in the passwd file is used 791038032Speter as the group. Based on code donated by Chip Rosenthal of 791138032Speter Unicom. 791238032Speter Allow `u' option to also accept user:group as a value, in the same 791338032Speter fashion as the U= mailer option. 791438032Speter Add the symbolic time zone name in the Arpanet format dates (as 791538032Speter a comment). This adds a new compile-time configuration 791638032Speter flag: TZ_TYPE can be set to TZ_TM_NAME (use the value 791738032Speter of (struct tm *)->tm_name), TZ_TM_ZONE (use the value 791838032Speter of (struct tm *)->tm_zone), TZ_TZNAME (use extern char 791938032Speter *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use 792038032Speter timezone()), or TZ_NONE (don't include the comment). Code 792138032Speter from Chip Rosenthal. 792238032Speter The "Timeout" option (formerly "r") is extended to allow suboptions. 792338032Speter For example, 792438032Speter O Timeout.helo = 2m 792538032Speter There are also two new suboptions "queuereturn" and 792638032Speter "queuewarn"; these subsume the old T option. Thus, to 792738032Speter set them both the preferred new syntax is 792838032Speter O Timeout.queuereturn = 5d 792938032Speter O Timeout.queuewarn = 4h 793038032Speter Sort queue by host name instead of by message priority if the 793138032Speter QueueSortOrder option (no short name) is set is set to 793238032Speter ``host''. This makes better use of the connection cache, 793338032Speter but may delay more ``interactive'' messages behind large 793438032Speter backlogs under some circumstances. This is probably a 793538032Speter good option if you have high speed links or don't do lots 793638032Speter of ``batch'' messages, but less good if you are using 793738032Speter something like PPP on a 14.4 modem. Based on code 793838032Speter contributed by Roy Mongiovi of Georgia Tech (my main 793938032Speter contribution was to make it configurable). 794038032Speter Save i-number of df file in qf file to simplify rebuilding of queue 794138032Speter after disastrous disk crash. Suggested by Kyle Jones of 794238032Speter UUNET; closely based on code from KJS DECWRL code written 794338032Speter by Paul Vixie. NOTA BENE: The qf files produced by 8.7 794438032Speter are NOT back compatible with 8.6 -- that is, you can convert 794538032Speter from 8.6 to 8.7, but not the other direction. 794638032Speter Add ``F=d'' mailer flag to disable all use of angle brackets in 794738032Speter route-addrs in envelopes; this is because in some cases 794838032Speter they can be sent to the shell, which interprets them as 794938032Speter I/O redirection. 795038032Speter Don't include error file (option E) with return-receipts; this 795138032Speter can be confusing. 795238032Speter Don't send "Warning: cannot send" messages to owner-* or 795338032Speter *-request addresses. Suggested by Christophe Wolfhugel 795438032Speter of the Institut Pasteur, Paris. 795538032Speter Allow -O command line flag to set long form options. 795638032Speter Add "MinQueueAge" option to set the minimum time between attempts 795738032Speter to run the queue. For example, if the queue interval 795838032Speter (-q value) is five minutes, but the minimum queue age 795938032Speter is fifteen minutes, jobs won't be tried more often than 796038032Speter once every fifteen minutes. This can be used to give 796138032Speter you more responsiveness if your delivery mode is set to 796238032Speter queue-only. 796338032Speter Allow "fileopen" timeout (default: 60 seconds) for opening 796438032Speter :include: and .forward files. 796538032Speter Add "-k", "-v", and "-z" flags to map definitions; these set the 796638032Speter key field name, the value field name, and the field 796738032Speter delimiter. The field delimiter can be a single character 796838032Speter or the sequence "\t" or "\n" for tab or newline. 796938032Speter These are for use by NIS+ and similar access methods. 797038032Speter Change maps to always strip quotes before lookups; the -q flag 797143730Speter turns off this behavior. Suggested by Motonori Nakamura. 797238032Speter Add "nisplus" map class. Takes -k and -v flags to choose the 797338032Speter key and value field names respectively. Code donated by 797438032Speter Sun Microsystems. 797538032Speter Add "hesiod" map class. The "file name" is used as the 797638032Speter "HesiodNameType" parameter to hes_resolve(3). Returns the 797738032Speter first value found for the match. Code donated by Scott 797838032Speter Hutton of Indiana University. 797938032Speter Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to 798038032Speter specify the name of the property that is searched as the 798138032Speter key and a -v flag to specify the name of the property that 798238032Speter is returned as the value (defaults to "members"). The 798338032Speter default map is "/aliases". Some code based on code 798438032Speter contributed by Robert La Ferla of Hot Software. 798538032Speter Add "text" map class. This does slow, linear searches through 798638032Speter text files. The -z flag specifies a column delimiter 798738032Speter (defaults to any sequence of white space), the -k flag 798838032Speter sets the key column number, and the -v flag sets the 798938032Speter value column number. Lines beginning with `#' are treated 799038032Speter as comments. 799138032Speter Add "program" map class to execute arbitrary programs. The search 799238032Speter key is presented as the last argument; the output is one 799338032Speter line read from the programs standard output. Exit statuses 799438032Speter are from sysexits.h. 799538032Speter Add "sequence" map class -- searches maps in sequence until it 799638032Speter finds a match. For example, the declarations: 799738032Speter Kmap1 ... 799838032Speter Kmap2 ... 799938032Speter Kmapseq sequence map1 map2 800038032Speter defines a map "mapseq" that first searches map1; if the 800138032Speter value is found it is returned immediately, otherwise 800238032Speter map2 is searched and the value returned. 800338032Speter Add "switch" map class. This is much like "sequence" except that 800438032Speter the ordering is fetched from an external file, usually 800538032Speter the system service switch. The parameter is the name of 800638032Speter the service to switch on, and the maps that it will use 800738032Speter are the name of the switch map followed by ".service_type". 800838032Speter For example, if the declaration of the map is 800938032Speter Ksample switch hosts 801038032Speter and the system service switch specifies that hosts are 801138032Speter looked up using dns and nis in that order, then this is 801238032Speter equivalent to 801338032Speter Ksample sequence sample.dns sample.nis 801438032Speter The subordinate maps (sample.*) must already be defined. 801538032Speter Add "user" map class -- looks up users using getpwnam. Takes a 801638032Speter "-v field" flag on the definition that tells what passwd 801738032Speter entry to return -- legal values are name, passwd, uid, gid, 801838032Speter gecos, dir, and shell. Generally expected to be used with 801938032Speter the -m (matchonly) flag. 802038032Speter Add "bestmx" map class -- returns the best MX value for the host 802138032Speter listed as the value. If there are several "best" MX records 802238032Speter for this host, one will be chosen at random. 802338032Speter Add "userdb" map class -- looks up entries in the user database. 802438032Speter The "file name" is actually the tag that will be used, 802538032Speter typically "mailname". If there are multiple entries 802638032Speter matching the name, the one chosen is undefined. 802738032Speter Add multiple queue timeouts (both return and warning). These are 802838032Speter set by the Precedence: or Priority: header fields to one of 802938032Speter three values. If a Priority: is set and has value "normal", 803064562Sgshapiro "urgent", or "non-urgent" the corresponding timeouts are 803138032Speter used. If no priority is set, the Precedence: is consulted; 803238032Speter if negative, non-urgent timeouts are used; if greater than 803338032Speter zero, urgent timeouts are used. Otherwise, normal timeouts 803438032Speter are used. The timeouts are set by setting the six timeouts 803538032Speter queue{warn,return}.{urgent,normal,non-urgent}. 803638032Speter Fix problem when a mail address is resolved to a $#error mailer 803738032Speter with a temporary failure indication; it works in SMTP, 803838032Speter but when delivering locally the mail is silently discarded. 803938032Speter This patch, from Kyle Jones of UUNET, bounces it instead 804038032Speter of queueing it (queueing is very hard). 804138032Speter When using /etc/hosts or NIS-style lookups, don't assume that 804238032Speter the first name in the list is the best one -- instead, 804338032Speter search for the first one with a dot. For example, if 804438032Speter an /etc/hosts entry reads 804538032Speter 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU 804638032Speter this change will use the second name as the canonical 804738032Speter machine name instead of the initial, unqualified name. 804838032Speter Change dequote map to replace spaces in quoted text with a value 804938032Speter indicated by the -s flag on the dequote map definition. 805038032Speter For example, ``Mdequote dequote -s_'' will change 805138032Speter "Foo Bar" into an unquoted Foo_Bar instead of leaving it 805238032Speter quoted (because of the space character). Suggested by Dan 805338032Speter Oscarsson for use in X.400 addresses. 805438032Speter Implement long macro names as ${name}; long class names can 805538032Speter be similarly referenced as $={name} and $~{name}. 805638032Speter Definitions are (e.g.) ``D{name}value''. Names that have 805738032Speter a leading lower case letter or punctuation characters are 805838032Speter reserved for internal use by sendmail; i.e., config files 805938032Speter should use names that begin with a capital letter. Based 806038032Speter on code contributed by Dan Oscarsson. 806138032Speter Fix core dump if getgrgid returns a null group list (as opposed 806238032Speter to an empty group list, that is, a pointer to a list 806338032Speter with no members). Fix from Andrew Chang of Sun Microsystems. 806438032Speter Fix possible core dump if malloc fails -- if the malloc in xalloc 806538032Speter failed, it called syserr which called newstr which called 806638032Speter xalloc.... The newstr is now avoided for "panic" messages. 806738032Speter Reported by Stuart Kemp of James Cook University. 806838032Speter Improve connection cache timeouts; previously, they were not even 806938032Speter checked if you were delivering to anything other than an 807038032Speter IPC-connected host, so a series of (say) local mail 807138032Speter deliveries could cause cached connections to be open 807238032Speter much longer than the specified timeout. 807338032Speter If an incoming message exceeds the maximum message size, stop 807438032Speter writing the incoming bytes to the queue data file, since 807538032Speter this can fill your mqueue partition -- this is a possible 807638032Speter denial-of-service attack. 807738032Speter Don't reject all numeric local user names unless HESIOD is 807838032Speter defined. It turns out that Posix allows all-numeric 807938032Speter user names. Fix from Tony Sanders of BSDI. 808038032Speter Add service switch support. If the local OS has a service 808138032Speter switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf 808238032Speter on DEC systems) that will be used; otherwise, it falls back 808338032Speter to using a local mechanism based on the ServiceSwitchFile 808438032Speter option (default: /etc/service.switch). For example, if the 808538032Speter service switch lists "files" and "nis" for the aliases 808638032Speter service, that will be the default lookup order. the "files" 808738032Speter ("local" on DEC) service type expands to any alias files 808838032Speter you listed in the configuration file, even if they aren't 808938032Speter actually file lookups. 809038032Speter Option I (NameServerOptions) no longer sets the "UseNameServer" 809138032Speter variable which tells whether or not DNS should be considered 809238032Speter canonical. This is now determined based on whether or not 809338032Speter "dns" is in the service list for "hosts". 809438032Speter Add preliminary support for the ESMTP "DSN" extension (Delivery 809538032Speter Status Notifications). DSN notifications override 809638032Speter Return-Receipt-To: headers, which are bogus anyhow -- 809738032Speter support for them has been removed. 809838032Speter Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer 809938032Speter definitions to define the types used in DSN returns for 810038032Speter MTA names, addresses, and diagnostics respectively. 810138032Speter Extend heuristic to force running in ESMTP mode to look for the 810238032Speter five-character string "ESMTP" anywhere in the 220 greeting 810338032Speter message (not just the second line). This is to provide 810438032Speter better compatibility with other ESMTP servers. 810538032Speter Print sequence number of job when running the queue so you can 810638032Speter easily see how much progress you have made. Suggested 810738032Speter by Peter Wemm of DIALix. 810838032Speter Map newlines to spaces in logged message-ids; some versions of 810938032Speter syslog truncate the rest of the line after newlines. 811038032Speter Suggested by Fletcher Mattox of U. Texas. 811138032Speter Move up forking for job runs so that if a message is split into 811238032Speter multiple envelopes you don't get "fork storms" -- this 811338032Speter also improves the connection cache utilization. 811438032Speter Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for 811538032Speter the purposes of refusing to send error returns. Suggested 811638032Speter by Motonori Nakamura of Ritsumeikan University. 811738032Speter Relax rules on when a file can be written when referenced from 811838032Speter the aliases file: use the default uid/gid instead of the 811938032Speter real uid/gid. This allows you to create a file owned by 812038032Speter and writable only by the default uid/gid that will work 812190792Sgshapiro all the time (without having the set-user-ID bit set). Change 812238032Speter suggested by Shau-Ping Lo and Andrew Cheng of Sun 812338032Speter Microsystems. 812438032Speter Add "DialDelay" option (no short name) to provide an "extra" 812538032Speter delay for dial on demand systems. If this is non-zero 812638032Speter and a connect fails, sendmail will wait this long and 812738032Speter then try again. If it takes longer than the kernel 812838032Speter timeout interval to establish the connection, this 812938032Speter option can give the network software time to establish 813038032Speter the link. The default units are seconds. 813138032Speter Move logging of sender information to be as early as possible; 813238032Speter previously, it could be delayed a while for SMTP mail 813338032Speter sent to aliases. Suggested by Brad Knowles of the 813438032Speter Defense Information Systems Agency. 813538032Speter Call res_init() before setting RES_DEBUG; this is required by 813638032Speter BIND 4.9.3, or so I'm told. From Douglas Anderson of 813738032Speter the National Computer Security Center. 813838032Speter Add xdelay= field in logs -- this is a transaction delay, telling 813938032Speter you how long it took to deliver to this address on the 814038032Speter last try. It is intended to be used for sorting mailing 814138032Speter lists to favor "quick" addresses. Provided for use by 814238032Speter the mailprio scripts (see below). 814338032Speter If a map cannot be opened, and that map is non-optional, and 814438032Speter an address requires that map for resolution, queue the 814538032Speter map instead of bouncing it. This involves creating a 814638032Speter pseudo-class of maps called "bogus-map" -- if a required 814738032Speter map cannot be opened, the class is changed to bogus-map; 814838032Speter all queries against bogus-map return "tempfail". The 814938032Speter bogus-map class is not directly accessible. A sample 815038032Speter implementation was donated by Jem Taylor of Glasgow 815138032Speter University Computing Service. 815238032Speter Fix a possible core dump when mailing to a program that talks 815338032Speter SMTP on its standard input. Fix from Keith Moore of 815438032Speter the University of Kentucky. 815538032Speter Make it possible to resolve filenames to $#local $: @ /filename; 815638032Speter previously, the "@" would cause it to not be recognized 815738032Speter as a file. Problem noted by Brian Hill of U.C. Davis. 815838032Speter Accept a -1 signal to re-exec the daemon. This only works if 815938032Speter argv[0] is a full path to sendmail. 816038032Speter Fix bug in "addr=..." field in O option on little-endian machines 816138032Speter -- the network number wasn't being converted to network 816238032Speter byte order. Patch from Kurt Lidl of Pix Technologies 816338032Speter Corporation. 816438032Speter Pre-initialize the resolver early on; this is to avoid a bug with 816538032Speter BIND 4.9.3 that can cause the _res.retry field to get 816638032Speter reset to zero, causing all name server lookups to time 816738032Speter out. Fix from Matt Day of Artisoft. 816838032Speter Restore T line (trusted users) in config file -- but instead of 816938032Speter locking out the -f flag, they just tell whether or not 817038032Speter an X-Authentication-Warning: will be added. This really 817138032Speter just creates new entries in class 't', so "Ft/file/name" 817238032Speter can be used to read trusted user names from a file. 817338032Speter Trusted users are also allowed to execute programs even 817438032Speter if they have a shell that isn't in /etc/shells. 817538032Speter Improve NEWDB alias file rebuilding so it will create them 817638032Speter properly if they do not already exist. This had been 817738032Speter a MAYBENEXTRELEASE feature in 8.6.9. 817838032Speter Check for @:@ entry in NIS maps before starting up to avoid 817938032Speter (but not prevent, sigh) race conditions. This ought to 818038032Speter be handled properly in ypserv, but isn't. Suggested by 818138032Speter Michael Beirne of Motorola. 818238032Speter Refuse connections if there isn't enough space on the filesystem 818338032Speter holding the queue. Contributed by Robert Dana of Wolf 818438032Speter Communications. 818538032Speter Skip checking for directory permissions in the path to a file 818638032Speter when checking for file permissions iff setreuid() 818738032Speter succeeded -- it is unnecessary in that case. This avoids 818838032Speter significant performance problems when looking for .forward 818938032Speter files. Based on a suggestion by Win Bent of USC. 819038032Speter Allow symbolic ruleset names. Syntax can be "Sname" to get an 819138032Speter arbitrary ruleset number assigned or "Sname = integer" 819238032Speter to assign a specific ruleset number. Reference is 819338032Speter $>name_or_number. Names can be composed of alphas, digits, 819438032Speter underscore, or hyphen (first character must be non-numeric). 819538032Speter Allow -o flag on AliasFile lines to make the alias file optional. 819638032Speter From Bryan Costales of ICSI. 819738032Speter Add NoRecipientAction option to handle the case where there is 819838032Speter no legal recipient header in the message. It can take 819938032Speter on values: 820038032Speter None Leave the message as is. The 820138032Speter message will be passed on even 820238032Speter though it is in technically 820338032Speter illegal syntax. 820438032Speter Add-To Add a To: header with any 820538032Speter recipients that it can find from 820638032Speter the envelope. This risks exposing 820738032Speter Bcc: recipients. 820838032Speter Add-Apparently-To Add an Apparently-To: header. This 820938032Speter has almost no redeeming social value, 821038032Speter and is provided only for back 821138032Speter compatibility. 821238032Speter Add-To-Undisclosed Add a header reading 821338032Speter To: undisclosed-recipients:; 821438032Speter which will have the effect of 821538032Speter making the message legal without 821638032Speter exposing Bcc: recipients. 821738032Speter Add-Bcc To add an empty Bcc: header. 821838032Speter There is a chance that mailers down 821938032Speter the line will delete this header, 822038032Speter which could cause exposure of Bcc: 822138032Speter recipients. 822238032Speter The default is NoRecipientAction=None. 822338032Speter Truncate (rather than delete) Bcc: lines in the header. This 822438032Speter should prevent later sendmails (at least, those that don't 822538032Speter themselves delete Bcc:) from considering this message to 822638032Speter be non-conforming -- although it does imply that non-blind 822738032Speter recipients can see that a Bcc: was sent, albeit not to whom. 822838032Speter Add SafeFileEnvironment option. If declared, files named as delivery 822938032Speter targets must be regular files in addition to the regular 823038032Speter checks. Also, if the option is non-null then it is used as 823138032Speter the name of a directory that is used as a chroot(2) 823238032Speter environment for the delivery; the file names listed in an 823338032Speter alias or forward should include the name of this root. 823438032Speter For example, if you run with 823538032Speter O SafeFileEnvironment=/arch 823638032Speter then aliases should reference "/arch/rest/of/path". If a 823738032Speter value is given, sendmail also won't try to save to 823838032Speter /usr/tmp/dead.letter (instead it just leaves the job in the 823938032Speter queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. 824038032Speter Support -A flag for alias files; this will comma concatenate like 824138032Speter entries. For example, given the aliases: 824238032Speter list: member1 824338032Speter list: member2 824438032Speter and an alias file declared as: 824538032Speter OAhash:-A /etc/aliases 824638032Speter the final alias inserted will be "list: member1,member2"; 824738032Speter without -A you will get an error on the second and subsequent 824838032Speter alias for "list". Contributed by Bryan Costales of ICSI. 824938032Speter Line-buffer transcript file. Suggested by Liudvikas Bukys. 825038032Speter Fix a problem that could cause very long addresses to core dump in 825138032Speter some special circumstances. Problem pointed out by Allan 825238032Speter Johannesen. 825338032Speter (Internal change.) Change interface to expand() (macro expansion) 825438032Speter to be simpler and more consistent. 825538032Speter Delete check for funny qf file names. This didn't really give 825638032Speter any extra security and caused some people some problems. 825738032Speter (If you -really- want this, define PICKY_QF_NAME_CHECK 825838032Speter at compile time.) Suggested by Kyle Jones of UUNET. 825938032Speter (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and 826038032Speter merge with DSN code; this is simpler and more consistent. 826138032Speter This may affect some people who have written their own 826238032Speter checkcompat() routine. 826338032Speter (Internal change.) Eliminate `D' line in qf file. The df file 826438032Speter is now assumed to be the same name as the qf file (with 826538032Speter the `q' changed to a `d', of course). 826638032Speter Avoid forking for delivery if all recipient mailers are marked as 826738032Speter "expensive" -- this can be a major cost on some systems. 826838032Speter Essentially, this forces sendmail into "queue only" mode 826938032Speter if all it is going to do is queue anyway. 827038032Speter Avoid sending a null message in some rather unusual circumstances 827138032Speter (specifically, the RCPT command returns a temporary 827238032Speter failure but the connection is lost before the DATA 827338032Speter command). Fix from Scott Hammond of Secure Computing 827438032Speter Corporation. 827538032Speter Change makesendmail to use a somewhat more rational naming scheme: 827638032Speter Makefiles and obj directories are named $os.$rel.$arch, 827738032Speter where $os is the operating system (e.g., SunOS), $rel is 827838032Speter the release number (e.g., 5.3), and $arch is the machine 827938032Speter architecture (e.g., sun4). Any of these can be omitted, 828038032Speter and anything after the first dot in a release number can 828138032Speter be replaced with "x" (e.g., SunOS.4.x.sun4). The previous 828238032Speter version used $os.$arch.$rel and was rather less general. 828338032Speter Change makesendmail to do a "make depend" in the target directory 828438032Speter when it is being created. This involves adding an empty 828538032Speter "depend:" entry in most Makefiles. 828638032Speter Ignore IDENT return value if the OSTYPE field returns "OTHER", 828738032Speter as indicated by RFC 1413. Pointed out by Kari Hurtta 828838032Speter of the Finnish Meteorological Institute. 828938032Speter Fix problem that could cause multiple responses to DATA command 829038032Speter on header syntax errors (e.g., lines beginning with colons). 829138032Speter Problem noted by Jens Thomassen of the University of Oslo. 829238032Speter Don't let null bytes in headers cause truncation of the rest of 829338032Speter the header. 829438032Speter Log Authentication-Warning:s. Suggested by Motonori Nakamura. 829538032Speter Increase timeouts on message data puts to allow time for receivers 829638032Speter to canonify addresses in headers on the fly. This is still 829738032Speter a rather ugly heuristic. From Motonori Nakamura. 829838032Speter Add "HasWildcardMX" suboption to ResolverOptions; if set, MX 829938032Speter records are not used when canonifying names, and when MX 830038032Speter lookups are done for addressing they must be fully 830138032Speter qualified. This is useful if you have a wildcard MX record, 830238032Speter although it may cause other problems. In general, don't use 830338032Speter wildcard MX records. Patch from Motonori Nakamura. 830438032Speter Eliminate default two-line SMTP greeting message. Instead of 830538032Speter adding an extra "ESMTP spoken here" line, the word "ESMTP" 830638032Speter is added between the first and second word of the first 830738032Speter line of the greeting message (i.e., immediately after the 830838032Speter host name). This eliminates the need for the BROKEN_SMTP_PEERS 830938032Speter compile flag. Old sendmails won't see the ESMTP, but that's 831038032Speter acceptable because SIZE was the only useful extension that 831138032Speter old sendmails understand. 831238032Speter Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 831338032Speter invoked state dumps. From Masaharu Onishi. 831438032Speter Allow on-line comments in .forward and :include: files; they are 831538032Speter introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> 831638032Speter is a space or a tab. This is intended for native 831738032Speter representation of non-ASCII sets such as Japanese, where 831838032Speter existing encodings would be unreadable or would lose 831938032Speter data -- for example, 832038032Speter <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori 832138032Speter (romanized/less information) 832238032Speter <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= 832338032Speter =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= 832438032Speter (with MIME encoding, not human readable) 832538032Speter <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B 832638032Speter (native encoding with ISO-2022-JP) 832738032Speter The last form is human readable in the Japanese environment. 832838032Speter Based on a fix from (surprise!) Motonori Nakamura. 832938032Speter Don't make SMTP error returns on MAIL FROM: line be "sticky" for all 833038032Speter messages to that host; these are most frequently associated 833138032Speter with addresses rather than the host, with the exception of 833238032Speter 421 (service shutting down). The effect was to cause queues 833338032Speter to sometimes take an excessive time to flush. Reported by 833438032Speter Robert Sargent of Southern Geographics Technologies and 833538032Speter Eric Prestemon of American University. 833638032Speter Add Nice=N mailer option to set the niceness at which a mailer will 833738032Speter run. This is actually a relative niceness (that is, an 833838032Speter increment on the background value). 833938032Speter Log queue runs that are skipped due to high loads. They are logged 834038032Speter at LOG_INFO priority iff the log level is > 8. Contributed 834138032Speter by Bruce Nagel of Data General. 834238032Speter Allow the error mailer to accept a DSN-style error status code 834338032Speter instead of an sysexits status code in the host part. 834438032Speter Anything with a dot will be interpreted as a DSN-style code. 834538032Speter Add new mailer flag: F=3 will tell translations to Quoted-Printable 834638032Speter to encode characters that might be munged by an EBCDIC system 834738032Speter in addition to the set required by RFC 1521. The additional 834838032Speter characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. 834938032Speter (Think of "IBM 360" as the mnemonic for this flag.) 835038032Speter Change check for mailing to files to look for a pathname of [FILE] 835138032Speter rather than looking for the mailer named *file*. The mapping 835238032Speter of leading slashes still goes to the *file* mailer. This 835338032Speter allows you to implement the *file* mailer as a separate 835438032Speter program, for example, to insert a Content-Length: header 835538032Speter or do special security policy. However, note that the usual 835638032Speter initial checking for the file permissions is still done, and 835738032Speter the program in question needs to be very careful about how 835838032Speter it does the file write to avoid security problems. 835938032Speter Be able to read ~root/.forward even if the path isn't accessible to 836038032Speter regular users. This is disrecommended because sendmail 836138032Speter sometimes does not run as root (e.g., when an unsafe option 836238032Speter is specified on the command line), but should otherwise be 836338032Speter safe because .forward files must be owned by the user for 836438032Speter whom mail is being forwarded, and cannot be a symbolic link. 836538032Speter Suggested by Forrest Aldrich of Wang Laboratories. 836638032Speter Add new "HostsFile" option that is the pathname to the /etc/hosts 836738032Speter file. This is used for canonifying hostnames when the 836838032Speter service type is "files". 836938032Speter Implement programs on F (read class from file) line. The syntax is 837038032Speter Fc|/path/to/program to read the output from the program 837138032Speter into class "c". 837238032Speter Probe the network interfaces to find alternate names for this 837338032Speter host. Requires the SIOCGIFCONF ioctl call. Code 837438032Speter contributed by SunSoft. 837538032Speter Add "E" configuration line to set or propagate environment 837638032Speter variables into children. "E<envar>" will propagate 837738032Speter the named variable from the environment when sendmail 837838032Speter was invoked into any children it calls; "E<envar>=<value>" 837938032Speter sets the named variable to the indicated value. Any 838038032Speter variables not explicitly named will not be in the child 838138032Speter environment. However, sendmail still forces an 838238032Speter "AGENT=sendmail" environment variable, in part to enforce 838338032Speter at least one environment variable, since many programs and 838438032Speter libraries die horribly if this is not guaranteed. 838538032Speter Change heuristic for rebuilding both NEWDB and NDBM versions of 838638032Speter alias databases -- new algorithm looks for the substring 838738032Speter "/yp/" in the file name. This is more portable and involves 838838032Speter less overhead. Suggested by Motonori Nakamura. 838938032Speter Dynamically allocate the queue work list so that you don't lose 839038032Speter jobs in large queue runs. The old QUEUESIZE compile parameter 839138032Speter is replaced by QUEUESEGSIZE (the unit of allocation, which 839238032Speter should not need to be changed) and the MaxQueueRunSize option, 839338032Speter which is the absolute maximum number of jobs that will ever 839438032Speter be handled in a single queue run. Based on code contributed 839538032Speter by Brian Coan of the Institute for Global Communications. 839638032Speter Log message when a message is dropped because it exceeds the maximum 839738032Speter message size. Suggested by Leo Bicknell of Virginia Tech. 839838032Speter Allow trusted users (those on a T line or in $=t) to use -bs without 839938032Speter an X-Authentication-Warning: added. Suggested by Mark Thomas 840038032Speter of Mark G. Thomas Consulting. 840138032Speter Announce state of compile flags on -d0.1 (-d0.10 throws in the 840238032Speter OS-dependent defines). The old semantic of -d0.1 to not 840338032Speter run the daemon in background has been moved to -d99.100, 840438032Speter and the old 52.5 flag (to avoid disconnect() from closing 840538032Speter all output files) has been moved to 52.100. This makes 840638032Speter things more consistent (flags below .100 don't change 840738032Speter semantics) and separates out the backgrounding so that 840838032Speter it doesn't happen automatically on other unrelated debugging 840938032Speter flags. 841038032Speter If -t is used but no addresses are found in the header, give an 841138032Speter error message rather than just doing nothing. Fix from 841238032Speter Motonori Nakamura. 841338032Speter On systems (like SunOS) where the effective gid is not necessarily 841438032Speter included in the group list returned by getgroups(), the 841538032Speter `restrictmailq' option could sometimes cause an authorized 841638032Speter user to not be able to use `mailq'. Fix from Charles Hannum 841738032Speter of MIT. 841838032Speter Allow symbolic service names for [IPC] mailers. Suggested by 841938032Speter Gerry Magennis of Logica International. 842038032Speter Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs 842138032Speter when running DNS. For example, if the name FTP.Foo.ORG is 842238032Speter a CNAME for Cruft.Foo.ORG, then when sitting on a machine in 842338032Speter the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" 842438032Speter if this option is not set, or "FTP.Foo.ORG" if it is set. 842538032Speter This is technically illegal under RFC 822 and 1123, but the 842638032Speter IETF is moving toward legalizing it. Note that turning on 842738032Speter this option is not sufficient to guarantee that a downstream 842838032Speter neighbor won't rewrite the address for you. 842938032Speter Add "-m" flag to makesendmail script -- this tells you what object 843038032Speter directory and Makefile it will use, but doesn't actually do 843138032Speter the make. 843238032Speter Do some additional checking on the contents of the qf file to try 843338032Speter to detect attacks against the qf file. In particular, 843438032Speter abort on any line beginning "From ", and add an "end of 843538032Speter file" line -- any data after that line is prohibited. 843638032Speter Always use /etc/sendmail.cf, regardless of the arbitrary vendor 843738032Speter choices. This can be overridden in the Makefile by using 843838032Speter either -DUSE_VENDOR_CF_PATH to get the vendor location 843938032Speter (to the extent that we know it) or by defining 844038032Speter _PATH_SENDMAILCF (which is a "hard override"). This allows 844138032Speter sendmail 8 to have more consistent installation instructions. 844238032Speter Allow macros on `K' line in config file. Suggested by Andrew Chang 844338032Speter of Sun Microsystems. 844438032Speter Improved symbol table hash function from Eric Wassenaar. This one 844538032Speter is at least 50% faster. 844638032Speter Fix problem that didn't notice that timeout on file open was a 844738032Speter transient error. Fix from Larry Parmelee of Cornell 844838032Speter University. 844938032Speter Allow comments (lines beginning with a `#') in files read for 845038032Speter classes. Suggested by Motonori Nakamura. 845138032Speter Make SIGINT (usually ^C) in test mode return to the prompt instead 845238032Speter of dropping out entirely. This makes testing some of the 845338032Speter name server lookups easier to deal with when there are 845438032Speter hung servers. From Motonori Nakamura. 845538032Speter Add new ${opMode} macro that is set to the current operation mode 845638032Speter (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by 845738032Speter Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. 845838032Speter Add new delivery mode (Odd) that defers all map lookups to queue runs. 845938032Speter Kind of like queue-only mode (Odq) except it tries to avoid 846038032Speter any external service requests; for dial-on-demand hosts that 846138032Speter want to minimize DNS lookups when mail is being queued. For 846238032Speter this to work you will also have to make sure that gethostbyname 846338032Speter of your local host name does not do a DNS lookup. 846438032Speter Improved handling of "out of space" conditions from John Myers of 846538032Speter Carnegie Mellon. 846638032Speter Improved security for mailing to files on systems that have fchmod(2) 846738032Speter support. 846838032Speter Improve "cannot send message for N days" message -- now says "could 846938032Speter not send for past N days". Suggested by Tom Moore of AT&T 847038032Speter Global Information Solutions. 847138032Speter Less misleading Subject: line on messages sent to postmaster only. 847238032Speter From Motonori Nakamura. 847338032Speter Avoid duplicate error messages on bad command line flags. From 847438032Speter Motonori Nakamura. 847538032Speter Better error message for case where ruleset 0 falls off the end 847638032Speter or otherwise does not resolve to a canonical triple. 847738032Speter Fix a problem that could cause multiple bounce messages if a bad 847838032Speter address was sent along with a good address to an SMTP 847938032Speter site where that SMTP site returned a 4yz code in response 848038032Speter to the final dot of the data. Problem reported by David 848138032Speter James of British Telecom. 848238032Speter Add "volatile" declarations so that gcc -O2 will work. Patches 848338032Speter from Alexander Dupuy of System Management ARTS. 848438032Speter Delete duplicates in MX lists -- believe it or not, there are sites 848538032Speter that list the same host twice in an MX list. This deletion 848638032Speter only works on adjacent preferences, so an MX list that 848738032Speter had A=5, B=10, A=15 would leave both As, but one that had 848838032Speter A=5, A=10, B=15 would reduce to A, B. This is intentional, 848938032Speter just in case there is something weird I haven't thought of. 849038032Speter Suggested by Barry Shein of Software Tool & Die. 849138032Speter SECURITY: .forward files cannot be symbolic links. If they are, 849238032Speter a bad guy can read your private files. 849338032Speter PORTABILITY FIXES: 849438032Speter Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>. 849538032Speter System V Release 4 from Motonori Nakamura of Ritsumeikan 849638032Speter University.

This means that the 851038032Speter sizeof operator returns only multiples of 8. 851138032Speter This requires adaptation of code that really 851238032Speter deals with 32 bit or 16 bit fields, such as IP 851338032Speter addresses or nameserver fields.'' 851438032Speter DG/UX 5.4.3 from Mark T.

It is not really 860338032Speter part of the release proper, and isn't fully supported; in 860438032Speter particular, it does not run on System V based systems and 860538032Speter never will. 860638032Speter CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon 860738032Speter to allow rmail to compile on systems that don't have 860838032Speter function prototypes and systems that don't have snprintf. 860938032Speter CONTRIB: add the "mailprio" scripts that will help you sort mailing 861038032Speter lists by transaction delay times so that addresses that 861138032Speter respond quickly get sent first. This is to prevent very 861238032Speter sluggish servers from delaying other peoples' mail. 861338032Speter Contributed by Tony Sanders of BSDI. 861438032Speter CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders 861538032Speter of BSDI. This has a lot of comments to help people out. 861638032Speter CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, 861738032Speter put this on the m4 command line. On GNU m4 (which 861838032Speter supports the __file__ primitive) you can run m4 in an 861938032Speter arbitrary directory -- use either: 862038032Speter m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf 862138032Speter or 862238032Speter m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf 862338032Speter On other versions of m4 that don't support __file__, you 862438032Speter can use: 862538032Speter m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ... 862638032Speter (Note the trailing slash on the _CF_DIR_ definition.) 862738032Speter Old versions of m4 will default to _CF_DIR_=.. for back 862838032Speter compatibility. 862938032Speter CONFIG: fix mail from <> so it will properly convert to 863038032Speter MAILER-DAEMON on local addresses. 863138032Speter CONFIG: fix code that was supposed to catch colons in host 863238032Speter names. Problem noted by John Gardiner Myers of CMU. 863338032Speter CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. 863438032Speter From Paul Riddle of the University of Maryland, Baltimore 863538032Speter County. 863638032Speter CONFIG: Catch and reject "." as a host address. 863738032Speter CONFIG: Generalize domaintable to look up all domains, not 863838032Speter just unqualified ones. 863938032Speter CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it 864038032Speter was never used and didn't work anyway. 864138032Speter CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer 864238032Speter and d on all mailers in the UUCP class. 864338032Speter CONFIG: Allow "user+detail" to be aliased specially: it will first 864438032Speter look for an alias for "user+detail", then for "user+*", and 864538032Speter finally for "user". This is intended for forwarding mail 864638032Speter for system aliases such as root and postmaster to a 864738032Speter centralized hub. 864838032Speter CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). 864938032Speter CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. 865038032Speter The F=8 flag is also set on the "relay" mailer, since 865138032Speter this is expected to be another sendmail. 865238032Speter CONFIG: avoid qualifying all UUCP addresses sent via SMTP with 865338032Speter the name of the UUCP_RELAY -- in some cases, this is the 865438032Speter wrong value (e.g., when we have local UUCP connections), 865538032Speter and this can create unreplyable addresses. From Chip 865638032Speter Rosenthal of Unicom. 865738032Speter CONFIG: add confRECEIVED_HEADER to change the format of the 865864562Sgshapiro Received: header inserted into all messages. Suggested by 865938032Speter Gary Mills of the University of Manitoba. 866038032Speter CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) 866143730Speter to get the old behavior. I did this upon observing 866238032Speter that almost everyone needed this feature, and that the 866338032Speter concept I was trying to make happen didn't work with 866438032Speter some user agents anyway. FEATURE(notsticky) still works, 866538032Speter but it is a no-op. 866638032Speter CONFIG: Add LUSER_RELAY -- the host to which unrecognized user 866738032Speter names are sent, rather than immediately diagnosing them 866838032Speter as User Unknown. 866938032Speter CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, 867038032Speter and RELAY_MAILER_ARGS to set the arguments for the 867138032Speter indicated mailers. All default to "IPC $h". Patch from 867238032Speter Larry Parmelee of Cornell University. 867338032Speter CONFIG: pop mailer needs F=n flag to avoid "annoying side effects 867438032Speter on the client side" and F=P to get an appropriate 867538032Speter return-path. From Kimmo Suominen. 867638032Speter CONFIG: add FEATURE(local_procmail) to use the procmail program 867738032Speter as the local mailer. For addresses of the form "user+detail" 867838032Speter the "detail" part is passed to procmail via the -a flag. 867938032Speter Contributed by Kimmo Suominen. 868038032Speter CONFIG: add MAILER(procmail) to add an interface to procmail for 868138032Speter use from mailertables. This lets you execute arbitrary 868238032Speter procmail scripts. Contributed by Kimmo Suominen. 868338032Speter CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. 868438032Speter CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From 868538032Speter Paul Southworth of CICNet Systems Support. 868638032Speter CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. 868738032Speter This causes the null return path to be rewritten as 868838032Speter MAILER-DAEMON; otherwise UUCP gets horribly confused. 868938032Speter From Michael Hohmuth of Technische Universitat Dresden. 869038032Speter CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that 869138032Speter list us as the best possible MX record to be treated as 869238032Speter though they were local (essentially, assume that they 869338032Speter are included in $=w). This can cause additional DNS 869438032Speter traffic, but is easier to administer if this fits your 869538032Speter local model. It does not work reliably if there are 869638032Speter multiple hosts that share the best MX preference. 869738032Speter Code contributed by John Oleynick of Rutgers. 869838032Speter CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted 869938032Speter SHell) instead of /bin/sh as the program used for delivery 870038032Speter to programs. If an argument is included, it is used as 870138032Speter the path to smrsh; otherwise, /usr/local/etc/smrsh is 870238032Speter assumed. 870338032Speter CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the 870438032Speter size of messages to the local and procmail mailers 870538032Speter respectively. Contributed by Brad Knowles of the Defense 870638032Speter Information Systems Agency. 870738032Speter CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments 870838032Speter (just like text outside of angle brackets) in order to 870938032Speter properly deal with ``group: addr1, ... addrN;'' syntax. 871038032Speter CONFIG: Require OSTYPE macro (the defaults really don't apply to 871138032Speter any real systems any more) and tweak the DOMAIN macro 871238032Speter so that it is less likely that users will accidentally use 871338032Speter the Berkeley defaults. Also, create some generic files 871438032Speter that really can be used in the real world. 871538032Speter CONFIG: Add new configuration macros to set character sets for 871638032Speter messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, 871738032Speter SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. 871838032Speter CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. 871938032Speter The old name will still be accepted for a while at least. 872038032Speter CONFIG: Implement DECNET_RELAY as spec for host to which DECNET 872138032Speter mail (.DECNET pseudo-domain or node::user) will be sent. 872238032Speter As with all relays, it can be ``mailer:hostname''. Suggested 872338032Speter by Scott Hutton. 872438032Speter CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed 872538032Speter by Barb Dijker of Labyrinth Computer Services. 872638032Speter CONFIG: change confCHECK_ALIASES to default to False -- it has poor 872738032Speter performance for large alias files, and this confused many 872838032Speter people. 872938032Speter CONFIG: Add confCF_VERSION to append local information to the 873038032Speter configuration version number displayed during SMTP startup. 873138032Speter CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it 873238032Speter would only work when locally addressed. Fix from 873338032Speter Edvard Tuinder of Cistron Internet Services. 873438032Speter CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option 873543730Speter "n" (CheckAliases) is set when rebuilding alias database. 873638032Speter Based on code contributed by Claude Marinier. 873738032Speter CONFIG: Allow mailertable to have values of the form 873838032Speter ``error:code message''. The ``code'' is a status code 873938032Speter derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. 874038032Speter Contributed by David James <dwj@agw.bt.co.uk>. 874138032Speter CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of 874238032Speter sender domains that will be replaced with the masquerade name. 874338032Speter These domains will not be treated as local, but if mail passes 874438032Speter through with sender addresses in those domains they will be 874538032Speter replaced by the masquerade name. These can also be specified 874638032Speter in a file using MASQUERADE_DOMAIN_FILE(filename). 874738032Speter CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope 874838032Speter as well as the header. Substantial improvements to this 874938032Speter code were contributed by Per Hedeland. 875038032Speter CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be 875138032Speter accessed from a mailertable to do CCSO ph lookups. Contributed 875238032Speter by Kimmo Suominen. 875338032Speter CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be 875438032Speter used to define cyrus and cyrusbb mailers (for IMAP support). 875538032Speter Contributed by John Gardiner Myers of Carnegie Mellon. 875638032Speter CONFIG: add confUUCP_MAILER to select default mailer to use for 875738032Speter UUCP addressing.

886864562Sgshapiro8.6.12/8.6.12 1995/03/28 886938032Speter Fix to IDENT code (it was getting the size of the reply buffer 887038032Speter too small, so nothing was ever accepted). Fix from several 887138032Speter people, including Allan Johannesen, Shane Castle of the 887238032Speter Boulder County Information Services, and Jeff Smith of 887338032Speter Warwick University (all arrived within a few hours of 887438032Speter each other!). 887538032Speter Fix a problem that could cause large jobs to run out of 887638032Speter file descriptors on systems that use vfork() rather 887738032Speter than fork(). 887838032Speter 887964562Sgshapiro8.6.11/8.6.11 1995/03/08 888038032Speter The ``possible attack'' message would be logged more often 888138032Speter than necessary if you are using Pine as a user agent. 888238032Speter The wrong host would be reported in the ``possible attack'' 888338032Speter message when attempted from IDENT. 888438032Speter In some cases the syslog buffer could be overflowed when 888538032Speter reporting the ``possible attack'' message. This can 888638032Speter cause denial of service attacks. Truncate the message 888738032Speter to 80 characters to prevent this problem. 888838032Speter When reading the IDENT response a loop is needed around the 888938032Speter read from the network to ensure that you don't get 889038032Speter partial lines. 889138032Speter Password entries without any shell listed (that is, a null 889238032Speter shell) wouldn't match as "ok". Problem noted by 889338032Speter Rob McMahon. 889438032Speter When running BIND 4.9.x a problem could occur because the 889538032Speter _res.options field is initialized differently than it 889638032Speter was historically -- this requires that sendmail call 889738032Speter res_init before it tweaks any bits. 889838032Speter Fix an incompatibility in openxscript() between the file open mode 889938032Speter and the stdio mode passed to fdopen. This caused UnixWare 890038032Speter 2.0 to have conniptions. Fix from Martin Sohnius of 890138032Speter Novell Labs Europe. 890238032Speter Fix problem with static linking of local getopt routine when 890338032Speter using GNU's ld command. Fix from John Kennedy of 890438032Speter Cal State Chico. 890538032Speter It was possible to turn off privacy flags.

Suggestions by *Hobbit* 890838032Speter and Liudvikas Bukys. 890938032Speter MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular) 891038032Speter from Spider Boardman. 891138032Speter CONFIG: No changes (version number only, to keep it in sync 891238032Speter with the binaries). 891338032Speter 891464562Sgshapiro8.6.10/8.6.10 1995/02/10 891538032Speter SECURITY: Diagnose bogus values to some command line flags that 891638032Speter could allow trash to get into headers and qf files. 891738032Speter Validate the name of the user returned by the IDENT protocol. 891838032Speter Some systems that really dislike IDENT send intentionally 891938032Speter bogus information. Problem pointed out by Michael Bushnell 892038032Speter of the Free Software Foundation. Has some security 892138032Speter implications. 892238032Speter Fix a problem causing error messages about DNS problems when 892338032Speter the host name contained a percent sign to act oddly 892438032Speter because it was passed as a printf-style format string. 892538032Speter In some cases this could cause core dumps. 892638032Speter Avoid possible buffer overrun in returntosender() if error 892738032Speter message is quite long. From Fletcher Mattox of the 892838032Speter University of Texas. 892938032Speter Fix a problem that would silently drop "too many hops" error 893038032Speter messages if and only if you were sending to an alias. 893138032Speter From Jon Giltner of the University of Colorado and 893238032Speter Dan Harton of Oak Ridge National Laboratory. 893338032Speter Fix a bug that caused core dumps on some systems if -d11.2 was 893438032Speter set and e->e_message was null. Fix from Bruce Nagel of 893538032Speter Data General. 893638032Speter Fix problem that can still cause df files to be left around 893738032Speter after "hop count exceeded" messages. Fix from Andrew 893838032Speter Chang and Shau-Ping Lo of SunSoft. 893938032Speter Fix a problem that can cause buffer overflows on very long 894038032Speter user names (as might occur if you piped to a program 894138032Speter with a lot of arguments). 894238032Speter Avoid returning an error and re-queueing if the host signature 894338032Speter is null; this can occur on addresses like ``user@.''. 894438032Speter Problem noted by Wesley Craig and the University of 894538032Speter Michigan. 894638032Speter Avoid possible calls to malloc(0) if MCI caching is turned 894738032Speter off. Bug fix from Pierre David of the Laboratoire 894838032Speter Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), 894938032Speter Universite de Versailles - St Quentin, and Jacky 895038032Speter Thibault. 895138032Speter Make a local copy of the line being sent via senttolist() -- in 895238032Speter some cases, buffers could get trashed by map lookups 895338032Speter causing it to do unexpected things. This also simplifies 895438032Speter some of the map code. 895538032Speter CONFIG: No changes (version number only, to keep it in sync 895638032Speter with the binaries). 895738032Speter 895864562Sgshapiro8.6.9/8.6.9 1994/04/19 895938032Speter Do all mail delivery completely disconnected from any terminal. 896038032Speter This provides consistency with daemon delivery and 896138032Speter may have some security implications. 896238032Speter Make sure that malloc doesn't get called with zero size, 896338032Speter since that fails on some systems. Reported by Ed 896438032Speter Hill of the University of Iowa. 896538032Speter Fix multi-line values for $e (SMTP greeting message). Reported 896638032Speter by Mike O'Connor of Ford Motor Company. 896738032Speter Avoid syserr if no NIS domain name is defined, but the map it 896838032Speter is trying to open is optional. From Win Bent of USC. 896938032Speter Changes for picky compilers from Ed Gould of Digital Equipment. 897038032Speter Hesiod support for UDB from Todd Miller of the University of 897138032Speter Colorado. Use "hesiod" as the service name in the U 897238032Speter option. 897338032Speter Fix a problem that failed to set the "authentic" host name (that 897438032Speter is, the one derived from the socket info) if you called 897538032Speter sendmail -bs from inetd. Based on code contributed by 897638032Speter Todd Miller (this problem was also reported by Guy Helmer 897738032Speter of Dakota State University). This also fixes a related 897838032Speter problem reported by Liudvikas Bukys of the University of 897938032Speter Rochester. 898038032Speter Parameterize "nroff -h" in all the Makefiles so people with 898138032Speter variant versions can use them easily. Suggested by 898238032Speter Peter Collinson of Hillside Systems. 898338032Speter SMTP "MAIL" commands with multiple ESMTP parameters required two 898438032Speter spaces between parameters instead of one. Reported by 898538032Speter Valdis Kletnieks of Virginia Tech. 898638032Speter Reduce the number of system calls during message collection by 898738032Speter using global timeouts around the collect() loop. This 898838032Speter code was contributed by Eric Wassenaar. 898938032Speter If the initial hostname name gathering results in a name 899038032Speter without a dot (usually caused by NIS misconfiguration) 899138032Speter and BIND is compiled in, directly access DNS to get 899238032Speter the canonical name. This should make life easier for 899338032Speter Solaris systems. If it still can't be resolved, and 899438032Speter if the name server is listed as "required", try again 899538032Speter in 30 seconds. If that also fails, exit immediately to 899638032Speter avoid bogus "config error: mail loops back to myself" 899738032Speter messages. 899838032Speter Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error 899938032Speter message to explain how much space was available and 900038032Speter sound a bit less threatening. Suggested by Stan Janet 900138032Speter of the National Institute of Standards and Technology. 900238032Speter If mail is delivered to an alias that has an owner, deliver any 900338032Speter requested return-receipt immediately, and strip the 900438032Speter Return-Receipt-To: header from the subsequent message. 900538032Speter This prevents a certain class of denial of service 900638032Speter attack, arguably gives more reasonable semantics, and 900738032Speter moves things more towards what will probably become a 900838032Speter network standard. Suggested by Christopher Davis of 900938032Speter Kapor Enterprises. 901038032Speter Add a "noreceipts" privacy flag to turn off all return receipts 901138032Speter without recompiling. 901238032Speter Avoid printing ESMTP parameters as part of the error message 901338032Speter if there are errors during parsing. This change is 901438032Speter purely cosmetic. 901538032Speter Avoid sending out error messages during the collect phase of 901638032Speter SMTP; there is an MVS mailer from UCLA that gets 901738032Speter confused by this. Of course, I think it's their bug.... 901838032Speter Check for the $j macro getting undefined, losing a dot, or getting 901938032Speter lost from $=w in the daemon before accepting a connection; 902038032Speter if it is, it dumps state, prints a LOG_ALERT message, 902138032Speter and drops core for debugging. This is an attempt to 902238032Speter track down a bug that I thought was long since gone. 902338032Speter If you see this, please forward the log fragment to 902438032Speter sendmail@sendmail.ORG. 902538032Speter Change OLD_NEWDB from a #ifdef to a #if so it can be turned off 902638032Speter with -DOLD_NEWDB=0 on the command line. From Christophe 902738032Speter Wolfhugel. 902838032Speter Instead of trying to truncate the listen queue for the server 902938032Speter SMTP port when the load average is too high, just close 903038032Speter the port completely and reopen it later as needed. 903138032Speter This ensures that the other end gets a quick "connection 903238032Speter refused" response, and that the connection can be 903338032Speter recovered later. In particular, some socket emulations 903438032Speter seem to get confused if you tweak the listen queue 903538032Speter size around and can never start listening to connections 903638032Speter again. The down side is that someone could start up 903738032Speter another daemon process in the interim, so you could 903838032Speter have multiple daemons all not listening to connections; 903938032Speter this could in turn cause the sendmail.pid file to be 904038032Speter incorrect. A better approach might be to accept the 904138032Speter connection and give a 421 code, but that could break 904243730Speter other mailers in mysterious ways and have paging behavior 904338032Speter implications. 904438032Speter Fix a glitch in TCP-level debugging that caused flag 16.101 to 904538032Speter set debugging on the wrong socket. From Eric Wassenaar. 904638032Speter When creating a df* temporary file, be sure you truncate any 904738032Speter existing data in the file -- otherwise system crashes 904838032Speter and the like could result in extra data being sent. 904938032Speter DOC: Replace the CHANGES-R5-R8 readme file with a paper in the 905038032Speter doc directory. This includes some additional 905138032Speter information. 905238032Speter CONFIG: change UUCP rules to never add $U! or $k! on the front 905338032Speter of recipient envelope addresses. This should have been 905438032Speter handled by the $&h trick, but broke if people were 905538032Speter mixing domainized and UUCP addresses. They should 905638032Speter probably have converted all the way over to uucp-uudom 905738032Speter instead of uucp-{new,old}, but the failure mode was to 905838032Speter loop the mail, which was bad news. 905938032Speter Portability fixes: 906038032Speter Newer BSDI systems (several people). 906138032Speter Older BSDI systems from Christophe Wolfhugel. 906238032Speter Intergraph CLIX, from Paul Southworth of CICNet. 906338032Speter UnixWare, from Evan Champion. 906438032Speter NetBSD from Adam Glass. 906538032Speter Solaris from Quentin Campbell of the University of 906638032Speter Newcastle upon Tyne. 906738032Speter IRIX from Dean Cookson and Bill Driscoll of Mitre 906838032Speter Corporation. 906938032Speter NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. 907038032Speter SunOS (it has setsid() and setvbuf() calls) from 907138032Speter Jonathan Kamens of OpenVision Technologies. 907238032Speter HP-UX from Tor Lillqvist. 907338032Speter New Files: 907438032Speter src/Makefile.CLIX 907538032Speter src/Makefile.NCR3000 907638032Speter doc/changes/Makefile 907738032Speter doc/changes/changes.me 907838032Speter doc/changes/changes.ps 907938032Speter 908064562Sgshapiro8.6.8/8.6.6 1994/03/21 908138032Speter SECURITY: it was possible to read any file as root using the 908238032Speter E (error message) option. Reported by Richard Jones; 908338032Speter fixed by Michael Corrigan and Christophe Wolfhugel. 908438032Speter 908564562Sgshapiro8.6.7/8.6.6 1994/03/14 908638032Speter SECURITY: it was possible to get root access by using weird 908738032Speter values to the -d flag. Thanks to Alain Durand of 908838032Speter INRIA for forwarding me the notice from the bugtraq 908938032Speter list. 909038032Speter 909164562Sgshapiro8.6.6/8.6.6 1994/03/13 909238032Speter SECURITY: the ability to give files away on System V-based 909338032Speter systems proved dangerous -- don't run as the owner 909438032Speter of a :include: file on a system that allows giveaways. 909538032Speter Unfortunately, this also applies to determining a 909638032Speter valid shell. 909738032Speter IMPORTANT: Previous versions weren't expiring old connections 909838032Speter in the connection cache for a long time under some 909938032Speter circumstances. This could result in resource exhaustion, 910038032Speter both at your end and at the other end. This checks the 910138032Speter connections for timeouts much more frequently. From 910238032Speter Doug Anderson of NCSC. 910338032Speter Fix a glitch that snuck in that caused programs to be run as 910438032Speter the sender instead of the recipient if the mail was 910538032Speter from a local user to another local user. From 910638032Speter Motonori Nakamura of Kyoto University. 910738032Speter Fix "wildcard" on /etc/shells matching -- instead of looking 910838032Speter for "*", look for "/SENDMAIL/ANY/SHELL/". From 910938032Speter Bryan Costales of ICSI. 911038032Speter Change the method used to declare the "statfs" availability; 911138032Speter instead of HASSTATFS and/or HASUSTAT with a ton of 911238032Speter tweaking in conf.c, there is a single #define called 911338032Speter SFS_TYPE which takes on one of six values (SFS_NONE 911438032Speter for no statfs availability, SFS_USTAT for the ustat(2) 911538032Speter syscall, SFS_4ARGS for a four argument statfs(2) call, 911638032Speter and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument 911738032Speter statfs(2) call with the declarations in <sys/vfs.h>, 911838032Speter <sys/mount.h>, or <sys/statfs.h> respectively). 911938032Speter Fix glitch in NetInfo support that could return garbage if 912038032Speter there was no "/locations/sendmail" property. From 912138032Speter David Meyer of the University of Virginia. 912238032Speter Change HASFLOCK from defined/not-defined to a 0/1 definition 912338032Speter to allow Linux to turn it off even though it is a 912438032Speter BSD-like system. 912538032Speter Allow setting of "ident" timeout to zero to turn off the ident 912638032Speter protocol entirely. 912738032Speter Make 7-bit stripping local to a connection (instead of to a 912838032Speter mailer); this allows you to specify that SMTP is a 912938032Speter 7-bit channel, but revert to 8-bit should it advertise 913038032Speter that it supports 8BITMIME. You still have to specify 913138032Speter mailer flag 7 to get this stripping at all. 913238032Speter Improve makesendmail script so it handles more cases automatically. 913338032Speter Tighten up restrictions on taking ownership of :include: files 913438032Speter to avoid problems on systems that allow you to give away 913538032Speter files. 913638032Speter Fix a problem that made it impossible to rebuild the alias 913738032Speter file if it was on a read-only file system. From 913838032Speter Harry Edmon of the University of Washington. 913938032Speter Improve MX randomization function. From John Gardiner Myers 914038032Speter of CMU. 914138032Speter Fix a minor glitch causing a bogus message to be printed (used 914238032Speter %s instead of %d in a printf string for the line number) 914338032Speter when a bad queue file was read. From Harry Edmon. 914438032Speter Allow $s to remain NULL on locally generated mail. I'm not 914538032Speter sure this is necessary, but a lot of people have complained 914638032Speter about it, and there is a legitimate question as to whether 914738032Speter "localhost" is legal as an 822-style domain. 914838032Speter Fix a problem with very short line lengths (mailer L= flag) in 914938032Speter headers. This causes a leading space to be added onto 915038032Speter continuation lines (including in the body!), and also 915138032Speter tries to wrap headers containing addresses (From:, To:, 915238032Speter etc) intelligently at the shorter line lengths. Problem 915338032Speter Reported by Lars-Johan Liman of SUNET Operations Center. 915438032Speter Log the real user name when logging syserrs, since these can have 915538032Speter security implications. Suggested by several people. 915638032Speter Fix address logging of cached connections -- it used to always 915738032Speter log the numeric address as zero. This is a somewhat 915838032Speter bogus implementation in that it does an extra system 915938032Speter call, but it should be an inexpensive one. Fix from 916038032Speter Motonori Nakamura. 916138032Speter Tighten up handling of short syslog buffers even more -- there 916238032Speter were cases where the outgoing relay= name was too long 916338032Speter to share a line with delay= and mailer= logging. 916438032Speter Limit the overhead on split envelopes to one open file descriptor 916538032Speter per envelope -- previously the overhead was three 916638032Speter descriptors. This was in response to a problem reported 916738032Speter by P{r (Pell) Emanuelsson. 916838032Speter Fixes to better handle the case of unexpected connection closes; 916938032Speter this redirects the output to the transcript so the info 917038032Speter is not lost. From Eric Wassenaar. 917138032Speter Fix potential string overrun if you macro evaluate a string that 917238032Speter has a naked $ at the end. Problem noted by James Matheson 917338032Speter <jmrm@eng.cam.ac.uk>. 917438032Speter Make default error number on $#error messages 553 (``Requested 917538032Speter action not taken: mailbox name not allowed'') instead of 917638032Speter 501 (``Syntax error in parameters or arguments'') to 917738032Speter avoid bogus "protocol error" messages. 917838032Speter Strip off any existing trailing dot on names during $[ ... $] 917938032Speter lookup. This prevents it from ending up with two dots 918038032Speter on the end of dot terminated names. From Wesley Craig 918138032Speter of the University of Michigan and Bryan Costales of ICSI. 918238032Speter Clean up file class reading so that the debugging information is 918338032Speter more informative. It hadn't been using setclass, so you 918438032Speter didn't see the class items being added. 918538032Speter Avoid core dump if you are running a version of sendmail where 918638032Speter NIS is compiled in, and you specify an NIS map, but 918738032Speter NIS is not running. Fix from John Oleynick of 918838032Speter Rutgers. 918938032Speter Diagnose bizarre case where res_search returns a failure value, 919038032Speter but sets h_errno to a success value. 919138032Speter Make sure that "too many hops" messages are considered important 919238032Speter enough to send an error to the Postmaster (that is, the 919338032Speter address specified in the P option). This fix should 919438032Speter help problems that cause the df file to be left around 919538032Speter sometimes -- unfortunately, I can't seem to reproduce 919638032Speter the problem myself. 919738032Speter Avoid core dump (null pointer reference) on EXPN command; this 919838032Speter only occurred if your log level was set to 10 or higher 919938032Speter and the target account was an alias or had a .forward file. 920038032Speter Problem noted by Janne Himanka. 920138032Speter Avoid "denial of service" attacks by someone who is flooding your 920238032Speter SMTP port with bad commands by shutting the connection 920338032Speter after 25 bad commands are issued. From Kyle Jones of 920438032Speter UUNET. 920538032Speter Fix core dump on error messages with very long "to" buffers; 920638032Speter fmtmsg overflows the message buffer. Fixed by trimming 920738032Speter the to address to 203 characters. Problem reported by 920838032Speter John Oleynick. 920938032Speter Fix configuration for HASFLOCK -- there were some spots where 921038032Speter a #ifndef was incorrectly #ifdef. Pointed out by 921138032Speter George Baltz of the University of Maryland. 921238032Speter Fix a typo in savemail() that could cause the error message To: 921338032Speter lists to be incorrect in some places. From Motonori 921438032Speter Nakamura. 921538032Speter Fix a glitch that can cause duplicate error messages on split 921638032Speter envelopes where an address on one of the lists has a 921738032Speter name server failure. Fix from Voradesh Yenbut of the 921838032Speter University of Washington. 921938032Speter Fix possible bogus pointer reference on ESMTP parameters that 922038032Speter don't have an ``=value'' part. 922138032Speter CNAME loops caused an error message to be generated, but also 922238032Speter re-queued the message. Changed to just re-queue the 922338032Speter message (it's really hard to just bounce it because 922438032Speter of the weird way the name server works in the presence 922538032Speter of CNAME loops). Problem noted by James M.R.Matheson 922638032Speter of Cambridge University. 922738032Speter Avoid giving ``warning: foo owned process doing -bs'' messages 922838032Speter if they use ``MAIL FROM:<foo>'' where foo is their true 922938032Speter user name. Suggested by Andreas Stolcke of ICSI. 923038032Speter Change the NAMED_BIND compile flag to be a 0/1 flag so you can 923138032Speter override it easily in the Makefile -- that is, you can 923238032Speter turn it off using -DNAMED_BIND=0. 923338032Speter If a gethostbyname(...) of an address with a trailing dot fails, 923438032Speter try it without the trailing dot. This is because if 923538032Speter you have a version of gethostbyname() that falls back 923638032Speter to NIS or the /etc/hosts file it will fail to find 923738032Speter perfectly reasonable names that just don't happen to 923838032Speter be dot terminated in the hosts file. You don't want to 923938032Speter strip the dot first though because we're trying to ensure 924038032Speter that country names that match one of your subdomains get 924138032Speter a chance. 924238032Speter PRALIASES: fix bogus output on non-null-terminated strings. 924338032Speter From Bill Gianopoulos of Raytheon. 924438032Speter CONFIG: Avoid rewriting anything that matches $w to be $j. 924538032Speter This was in code intended to only catch the self-literal 924638032Speter address (that is, [1.2.3.4], where 1.2.3.4 is your 924738032Speter IP address), but the code was broken. However, it will 924838032Speter still do this if $M is defined; this is necessary to 924938032Speter get client configurations to work (sigh). Note that this 925038032Speter means that $M overrides :mailname entries in the user 925138032Speter database! Problem noted by Paul Southworth. 925238032Speter CONFIG: Fix definition of Solaris help file location. From 925338032Speter Steve Cliffe <steve@gorgon.cs.uow.edu.au>. 925438032Speter CONFIG: Fix bug that broke news.group.USENET mappings. 925538032Speter CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, 925638032Speter and USENET_MAILER_MAX to tweak the maximum message 925738032Speter size for various mailers. 925838032Speter CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] 925938032Speter instead of assuming that it is "inews" for consistency 926038032Speter with other mailers. From Michael Corrigan of UC San Diego. 926138032Speter CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, 926238032Speter qualify the address in the SMTP envelope as user@{relay|hub} 926338032Speter instead of user@$j. From Bill Wisner of The Well. 926438032Speter CONFIG: Fix route-addr syntax in nullrelay configuration set. 926538032Speter CONFIG: Don't turn off case mapping of user names in the local 926638032Speter mailer for IRIX. This was different than most every other 926738032Speter system. 926838032Speter CONFIG: Avoid infinite loops on certainly list:; syntaxes in 926938032Speter envelope. Noted by Thierry Besancon 927038032Speter <besancon@excalibur.ens.fr>. 927138032Speter CONFIG: Don't include -z by default on uux line -- most systems 927238032Speter don't want it set by default. Pointed out by Philippe 927338032Speter Michel of Thomson CSF. 927438032Speter CONFIG: Fix some bugs with mailertables -- for example, if your 927538032Speter host name was foo.bar.ray.com and you matched against 927638032Speter ".ray.com", the old implementation bound %1 to "bar" 927738032Speter instead of "foo.bar". Also, allow "." in the mailertable 927838032Speter to match anything -- essentially, take over SMART_HOST. 927938032Speter This also moves matching of explicit local host names 928038032Speter before the mailertable so they don't have to be special 928138032Speter cased in the mailertable data. Reported by Bill 928238032Speter Gianopoulos of Raytheon; the fix for the %1 binding 928338032Speter problem was contributed by Nicholas Comanos of the 928438032Speter University of Sydney. 928538032Speter CONFIG: Don't include "root" in class $=L (users to deliver 928638032Speter locally, even if a hub or relay exists) by default. 928738032Speter This is because of the known bug where definition of 928838032Speter both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore 928938032Speter both and deliver into the local mailbox. 929038032Speter CONFIG: Move up bitdomain and uudomain handling so that they 929138032Speter are done before .UUCP class matching; uudomain was 929238032Speter reported as ineffective before. This also frees up 929338032Speter diversion 8 for future use. Problem reported by Kimmo 929438032Speter Suominen. 929538032Speter CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) 929638032Speter into host names. As pointed out by Jonathan Kamens, 929738032Speter these are often used because either the forward or reverse 929838032Speter mapping is broken; this translation makes it broken again. 929938032Speter DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo 930038032Speter Suominen. 930138032Speter Portability fixes: 930238032Speter Unicos from David L. Kensiski of Sterling Software. 930338032Speter DomainOS from Don Lewis of Silicon Systems. 930438032Speter GNU m4 1.0.3 from Karst Koymans of Utrecht University. 930538032Speter Convex from Kimmo Suominen <kim@tac.nyc.ny.us>. 930638032Speter NetBSD from Adam Glass <glass@sun-lamp.cs.berkeley.edu>. 930738032Speter BSD/386 from Tony Sanders of BSDI. 930838032Speter Apollo from Eric Wassenaar. 930938032Speter DGUX from Doug Anderson. 931038032Speter Sequent DYNIX/ptx 2.0 from Tim Wright of Sequent. 931138032Speter NEW FILES: 931238032Speter src/Makefile.DomainOS 931338032Speter src/Makefile.PTX 931438032Speter src/Makefile.SunOS.5.1 931538032Speter src/Makefile.SunOS.5.2 931638032Speter src/Makefile.SunOS.5.x 931738032Speter src/mailq.1 931838032Speter cf/ostype/domainos.m4 931938032Speter doc/op/Makefile 932038032Speter doc/intro/Makefile 932138032Speter doc/usenix/Makefile 932238032Speter 932364562Sgshapiro8.6.5/8.6.5 1994/01/13 932438032Speter Security fix: /.forward could be owned by anyone (the test 932538032Speter to allow root to own any file was backwards). From 932638032Speter Bob Campbell at U.C. Berkeley. 932738032Speter Security fix: group ids were not completely set when programs 932838032Speter were invoked. This caused programs to have group 932938032Speter permissions they should not have had (usually group 933038032Speter daemon instead of their own group). In particular, 933138032Speter Perl scripts would refuse to run. 933238032Speter Security: check to make sure files that are written are not 933338032Speter symbolic links (at least under some circumstances). 933438032Speter Although this does not respond to a specific known 933538032Speter attack, it's just a good idea. Suggested by 933638032Speter Christian Wettergren. 933738032Speter Security fix: if a user had an NFS mounted home directory on 933838032Speter a system with a restricted shell listed in their 933938032Speter /etc/passwd entry, they could still execute any 934038032Speter program by putting that in their .forward file. 934138032Speter This fix prevents that by insisting that their shell 934238032Speter appear in /etc/shells before allowing a .forward to 934338032Speter execute a program or write a file. You can disable 934438032Speter this by putting "*" in /etc/shells. It also won't 934538032Speter permit world-writable :include: files to reference 934638032Speter programs or files (there's no way to disable this). 934743730Speter These behaviors are only one level deep -- for 934838032Speter example, it is legal for a world-writable :include: 934938032Speter file to reference an alias that writes a file, on 935038032Speter the assumption that the alias file is well controlled. 935138032Speter Security fix: root was not treated suspiciously enough when 935238032Speter looking into subdirectories. This would potentially 935338032Speter allow a cracker to examine files that were publicly 935438032Speter readable but in a non-publicly searchable directory. 935538032Speter Fix a problem that causes an error on QUIT on a cached 935638032Speter connection to create problems on the current job. 935738032Speter These are typically unrelated, so errors occur in 935838032Speter the wrong place. 935938032Speter Reset CurrentLA in sendall() -- this makes sendmail queue 936038032Speter runs more responsive to load average, and fixes a 936138032Speter problem that ignored the load average in locally 936238032Speter generated mail. From Eric Wassenaar. 936338032Speter Fix possible core dump on aliases with null LHS. From 936438032Speter John Orthoefer of BB&N. 936538032Speter Revert to using flock() whenever possible -- there are just 936638032Speter too many bugs in fcntl() locking, particularly over 936738032Speter NFS, that cause sendmail to fail in perverse ways. 936838032Speter Fix a bug that causes the connection cache to get confused 936938032Speter when sending error messages. This resulted in 937038032Speter "unexpected close" messages. It should fix itself 937138032Speter on the following queue run. Problem noted by 937238032Speter Liudvikas Bukys of the University of Rochester. 937338032Speter Include $k in $=k as documented in the Install & Op Guide. 937438032Speter This seems odd, but it was documented.... From 937538032Speter Michael Corrigan of UCSD. 937638032Speter Fix problem that caused :include:s from alias files to be 937738032Speter forced to be owned by root instead of daemon 937838032Speter (actually DefUid). From Tim Irvin. 937938032Speter Diagnose unrecognized I option values -- from Mortin Forssen 938038032Speter of the Chalmers University of Technology. 938138032Speter Make "error" mailer work consistently when there is no error 938238032Speter code associated with it -- previously it returned OK 938338032Speter even though there was a real problem. Now it assumes 938438032Speter EX_UNAVAILABLE. 938538032Speter Fix bug that caused the last header line of messages that had 938638032Speter no body and which were terminated with EOF instead of 938738032Speter "." to be discarded. Problem noted by Liudvikas Bukys. 938838032Speter Fix core dump on SMTP mail to programs that failed -- it tried 938938032Speter to go to a "next MX host" when none existed, causing 939038032Speter a core dump. From der Mouse at McGill University. 939138032Speter Change IDENTPROTO from a defined/not defined to a 0/1 switch; 939238032Speter this makes it easier to turn it off (using 939338032Speter -DIDENTPROTO=0 in the Makefile). From der Mouse. 939438032Speter Fix YP_MASTER_NAME store to use the unupdated result of 939538032Speter gethostname() (instead of myhostname(), which tries 939638032Speter to fully qualify the name) to be consistent with 939738032Speter SunOS. If your hostname is unqualified, this fixes 939838032Speter transfers to slave servers. Bug noted by Keith 939938032Speter McMillan of Ameritech Services, Inc. 940038032Speter Fix Ultrix problem: gethostbyname() can return a very large 940138032Speter (> 500) h_length field, which causes the sockaddr 940238032Speter to be trashed. Use the size of the sockaddr instead. 940338032Speter Fix from Bob Manson of Ohio State. 940438032Speter Don't assume "-a." on host lookups if NAMED_BIND is not 940538032Speter defined -- this confuses gethostbyname on hosts 940638032Speter file lookups, which doesn't understand the trailing 940738032Speter dot convention. 940838032Speter Log SMTP server subprocesses that die with a signal instead 940938032Speter of from a clean exit. 941038032Speter If you don't have option "I" set, don't assume that a DNS 941138032Speter "host unknown" message is authoritative -- it 941238032Speter might still be found in /etc/hosts. 941338032Speter Fix a problem that would cause Deferred: messages to be sent 941438032Speter as the subject of an error message, even though the 941538032Speter actual cause of a message was more severe than that. 941638032Speter Problem noted by Chris Seabrook of OSSI. 941738032Speter Fix race condition in DBM alias file locking. From Kyle 941838032Speter Jones of UUNET. 941938032Speter Limit delivery syslog line length to avoid bugs in some 942038032Speter versions of syslog(3). This adds a new compile time 942138032Speter variable SYSLOG_BUFSIZE. From Jay Plett of Princeton 942238032Speter University, which is in turn derived from IDA. 942338032Speter Fix quotes inside of comments in addresses -- previously 942438032Speter it insisted that they be balanced, but the 822 spec 942538032Speter says that they should be ignored. 942638032Speter Dump open file state to syslog upon receiving SIGUSR1 (for 942738032Speter debugging). This also evaluates ruleset 89, if set 942838032Speter (with the null input), and logs the result. This 942938032Speter should be used sparingly, since the rewrite process 943038032Speter is not reentrant. 943138032Speter Change -qI, -qR, and -qS flags to be case-insensitive as 943238032Speter documented in the Bat Book. 943338032Speter If the mailer returned EX_IOERR or EX_OSERR, sendmail did not 943438032Speter return an error message and did not requeue the message. 943538032Speter Fix based on code from Roland Dirlewanger of 943638032Speter Reseau Regional Aquarel, Bordeaux, France. 943738032Speter Fix a problem that caused a seg fault if you got a 421 error 943838032Speter code during some parts of connection initialization. 943938032Speter I've only seen this when talking to buggy mailers on 944038032Speter the other end, but it shouldn't give a seg fault in 944138032Speter any case. From Amir Plivatsky. 944238032Speter Fix core dump caused by a ruleset call that returns null. 944338032Speter Fix from Bryan Costales of ICSI. 944438032Speter Full-Name: field was being ignored. Fix from Motonori Nakamura 944538032Speter of Kyoto University. 944638032Speter Fix a possible problem with very long input lines in setproctitle. 944738032Speter From P{r Emanuelsson. 944838032Speter Avoid putting "This is a warning message" out on return receipts. 944938032Speter Suggested by Douglas Anderson. 945038032Speter Detect loops caused by recursive ruleset calls. Suggested by 945138032Speter Bryan Costales. 945238032Speter Initialize non-alias maps during alias rebuilds -- they may be 945338032Speter needed for parsing. Problem noted by Douglas Anderson. 945438032Speter Log sender address even if no message was collected in SMTP 945538032Speter (e.g., if all RCPTs failed). Suggested by Motonori 945638032Speter Nakamura. 945738032Speter Don't reflect the owner-list contents into the envelope sender 945838032Speter address if the value contains ", :, /, or | (to avoid 945938032Speter illegal addresses appearing there). 946038032Speter Efficiency hack for toktype macro -- from Craig Partridge of 946138032Speter BB&N. 946238032Speter Clean up DNS error printing so that a host name is always 946338032Speter included. 946438032Speter Remember to set $i during queue runs. Reported by Stephen 946538032Speter Campbell of Dartmouth University. 946638032Speter If the environment variable HOSTALIASES is set, use it during 946738032Speter canonification as the name of a file with per-user host 946838032Speter translations so that headers are properly mapped. Reported 946938032Speter by Anne Bennett of Concordia University. 947038032Speter Avoid printing misleading error message if SMTP mailer (not 947138032Speter using [IPC]) should die on a core dump. 947238032Speter Avoid incorrect diagnosis of "file 1 closed" when it is caused 947338032Speter by the other end closing the connection. From 947438032Speter Dave Morrison of Oracle. 947538032Speter Improve several of the error messages printed by "mailq" 947638032Speter to include a host name or other useful information. 947738032Speter Add NetInfo preliminary support for NeXT systems. From Vince 947838032Speter DeMarco. 947938032Speter Fix a glitch that sometimes caused :include:s that pointed to 948038032Speter NFS filesystems that were down to give an "aliasing/ 948138032Speter forwarding loop broken" message instead of queueing 948238032Speter the message for retry. Noted by William C Fenner of 948338032Speter the NRL Connection Machine Facility. 948438032Speter Fix a problem that could cause a core dump if the input sequence 948538032Speter had (or somehow acquired) a \231 character. 948638032Speter Make sure that route-addrs always have <angle brackets> around 948738032Speter them in non-SMTP envelopes (SMTP envelopes already do 948838032Speter this properly). 948938032Speter Avoid weird headers on unbalanced punctuation of the form: 949038032Speter ``Joe User <user)'' -- this caused reference to the 949138032Speter null macro. Fix from Rick McCarty of IO.COM. 949238032Speter Fix a problem that caused an alias "user: user@local.host" to 949338032Speter not have the QNOTREMOTE bit set; this caused configs 949438032Speter to act as if FEATURE(notsticky) was defined even when 949538032Speter it was not. The effect of the problem was to make it 949638032Speter very hard to to set up satellite sites that had a few 949738032Speter local accounts, with everything else forwarded to a 949838032Speter corporate hub. Reported by Detlef Drewanz of the 949938032Speter University of Rostock and Mark Frost of NCD. 950038032Speter Change queuing to not call rulesets 3, {1 or 2}, 4 on header 950138032Speter addresses. This is more efficient (fewer name server 950238032Speter calls) and fixes certain unusual configurations, such 950338032Speter as those that have ruleset 4 do something that is 950438032Speter non-idempotent unless a mailer-specific ruleset did 950538032Speter something else. Problem reported by Brian J. Coan 950638032Speter of the Institute for Global Communications. 950738032Speter Fix the "obsolete argument" routine in main to better understand 950838032Speter new arguments. For example, if you used ``sendmail 950938032Speter -C config -v -q'' it would choke on the -q because 951038032Speter the -C would stop looking for old-format arguments. 951138032Speter Fix the code that was intended to allow two users to forward their 951238032Speter mail to the same program and have them appear unique. 951338032Speter Portability fixes for: 951438032Speter SCO UNIX from Murray Kucherawy. 951538032Speter SCO Open Server 3.2v4 from Philippe Brand. 951638032Speter System V Release 4 from Rick Ellis and others. 951738032Speter OSF/1 from Steve Campbell. 951838032Speter DG/UX from Ben Mesander of the USGS and Bryan Curnutt 951938032Speter of Stoner Associates. 952038032Speter Motorola SysV88 from Kevin Johnson of Motorola. 952138032Speter Solaris 2.3 from Casper H.S.

NOTA BENE: the location 953538032Speter of the config file has moved to /usr/lib 953638032Speter to match the HP-UX version of sendmail. 953738032Speter CONFIG: Don't do any recipient rewriting on relay mailer; 953838032Speter since this is intended only for internal use, the 953938032Speter usual RFC 821/822/1123 rules can be relaxed. The 954038032Speter main point of this is to avoid munging (ugh) UUCP 954138032Speter addresses when relaying internally. 954238032Speter CONFIG: fix typo in mailer/uucp.m4 that mutilates list:; 954338032Speter syntax addresses delivered via UUCP. Solution 954438032Speter provided by Peter Wemm. 954538032Speter CONFIG: fix thumb-fumble in default UUCP relaying in ruleset 954638032Speter zero; it caused double @ signs in addresses. From 954738032Speter Irving Reid of the University of Toronto. 954838032Speter CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 954938032Speter from Markku Toijala of ICL Personal Systems Oy. 955038032Speter CONFIG: Add trailing "." on pseudo-domains for consistency; 955138032Speter this fixes a problem (noted by Al Whaley of Sunnyside) 955238032Speter that made it hard to recognize your own pseudodomain 955338032Speter names. 955438032Speter CONFIG: catch "@host" syntax errors (i.e., null local-parts) 955538032Speter rather than letting them get "local configuration 955638032Speter error"s. Problem noted by John Gardiner Myers. 955738032Speter CONFIG: add uucp-uudom mailer variant, based on code posted 955838032Speter by Spider Boardman <spider@Orb.Nashua.NH.US>; this 955938032Speter has uucp-dom semantics but old UUCP syntax. This 956038032Speter also permits "uucp-old" as an alias for "uucp" and 956138032Speter "uucp-new" as a synonym for "suucp" for consistency. 956238032Speter CONFIG: add POP mailer support (from Kimmo Suominen 956338032Speter <kim@grendel.lut.fi>). 956438032Speter CONFIG: drop CSNET_RELAY support -- CSNET is long gone. 956538032Speter CONFIG: fix bug caused with domain literal addresses (e.g., 956638032Speter ``[128.32.131.12]'') when FEATURE(allmasquerade) 956738032Speter was set; it would get an additional @masquerade.host 956838032Speter added to the address. Problem noted by Peter Wan 956938032Speter of Georgia Tech. 957038032Speter CONFIG: make sure that the local UUCP name is in $=w. From 957138032Speter Jim Murray of Stratus. 957238032Speter CONFIG: changes to UUCP rewriting to simulate IDA-style "V" 957338032Speter mailer flag. Briefly, if you are sending to host 957438032Speter "foo", then it rewrites "foo!...!baz" to "...!baz", 957538032Speter "foo!baz" remains "foo!baz", and anything else has 957638032Speter the local name prepended. 957738032Speter CONFIG: portability fixes for HP-UX. 957838032Speter DOC: several minor problems fixed in the Install & Op Guide. 957938032Speter MAKEMAP: fix core dump problem on lines that are too long or 958038032Speter which lack newline.

From Tom Ferrin of UC 958338032Speter San Francisco Computer Graphics Lab. 958438032Speter SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: 958538032Speter On HP-UX, /etc/sendmail.cf has been moved to 958638032Speter /usr/lib/sendmail.cf to match HP sendmail. 958738032Speter Permissions have been tightened up on world-writable 958838032Speter :include: files and accounts that have shells 958938032Speter that are not listed in /etc/shells. This may 959038032Speter cause some .forward files that have worked 959138032Speter before to start failing. 959238032Speter SIGUSR1 dumps some state to the log. 959338032Speter NEW FILES: 959438032Speter src/Makefile.DGUX 959538032Speter src/Makefile.Dynix 959638032Speter src/Makefile.FreeBSD 959738032Speter src/Makefile.Mach386 959838032Speter src/Makefile.NetBSD 959938032Speter src/Makefile.RISCos 960038032Speter src/Makefile.SCO 960138032Speter src/Makefile.SVR4 960238032Speter src/Makefile.Titan 960338032Speter cf/mailer/pop.m4 960438032Speter cf/ostype/bsdi1.0.m4 960538032Speter cf/ostype/dgux.m4 960638032Speter cf/ostype/dynix3.2.m4 960738032Speter cf/ostype/sco3.2.m4 960838032Speter makemap/Makefile.dist 960938032Speter praliases/Makefile.dist 961038032Speter 961164562Sgshapiro8.6.4/8.6.4 1993/10/31 961238032Speter Repair core-dump problem (write to read-only memory segment) 961338032Speter if you fall back to the return-to-Postmaster case in 961438032Speter savemail. Problem reported by Richard Liu. 961538032Speter Immediately diagnose bogus sender addresses in SMTP. This 961638032Speter makes quite certain that crackers can't use this 961738032Speter class of attack. 961838032Speter Reliability Fix: check return value from fclose() and fsync() 961938032Speter in a few critical places. 962038032Speter Minor problem in initsys() that reversed a condition for 962138032Speter redirecting the output channel on queue runs. It's 962238032Speter not clear this code even does anything. From Eric 962338032Speter Wassenaar of the Dutch National Institute for Nuclear 962438032Speter and High-Energy Physics. 962538032Speter Fix some problems that caused queue runs to do "too much work", 962638032Speter such as double-reading the Errors-To: header. From 962738032Speter Eric Wassenaar. 962838032Speter Error messages on writing the temporary file (including the 962938032Speter data file) were getting suppressed in SMTP -- this 963038032Speter fix causes them to be properly reported. From Eric 963138032Speter Wassenaar. 963238032Speter Some changes to support AF_UNIX sockets -- this will only 963338032Speter really become relevant in the next release, but some 963438032Speter people need it for local patches. From Michael 963538032Speter Corrigan of UC San Diego. 963638032Speter Use dynamically allocated memory (instead of static buffers) 963738032Speter for macros defined in initsys() and settime(); since 963838032Speter these can have different values depending on which 963938032Speter envelope they are in. From Eric Wassenaar. 964038032Speter Improve logging to show ctladdr on to= logging; this tells you 964138032Speter what uid/gid processes ran as. 964238032Speter Fix a problem that caused error messages to be discarded if 964338032Speter the sender address was unparseable for some reason; 964438032Speter this was supposed to fall back to the "return to 964538032Speter postmaster" case. 964638032Speter Improve aliaswait backoff algorithm. 964738032Speter Portability patches for Linux (8.6.3 required another header 964838032Speter file) (from Karl London) and SCO UNIX. 964938032Speter CONFIG: patch prog mailer to not strip host name off of envelope 965038032Speter addresses (so that it matches local again). From 965138032Speter Christopher Davis. 965238032Speter CONFIG: change uucp-dom mailer so that "<>" translates to $n; 965338032Speter this prevents uux from seeing lines with null names like 965438032Speter ``From Sat Oct 30 14:55:31 1993''. From Motonori 965538032Speter Nakamura of Kyoto University. 965638032Speter CONFIG: handle <list:;> syntax correctly. This isn't legal, but 965738032Speter it shouldn't fail miserably.

It was previously listed as 967038032Speter the current time. Bug reported by Eric Hagberg of 967138032Speter Cornell University Medical College. 967238032Speter If there is an error when writing the body of a message, 967338032Speter don't send the trailing dot and wait for a response 967438032Speter in sender SMTP, as this could cause the connection to 967538032Speter hang up under some bizarre circumstances. From Eric 967638032Speter Wassenaar. 967738032Speter Fix some server SMTP synchronization problems caused when 967838032Speter connections fail during message collection. From 967938032Speter Eric Wassenaar. 968038032Speter Fix a problem that can cause srvrsmtp to reject mail if the 968138032Speter name server is down -- it accepts the RCPT but rejects 968238032Speter the DATA command. Problem reported by Jim Murray of 968338032Speter Stratus. 968438032Speter Fix a problem that can cause core dumps if the config file 968538032Speter incorrectly resolves to a null hostname. Reported by 968638032Speter Allan Johannesen of WPI. 968738032Speter Non-root use of -C flag, dangerous -f flags, and use of -oQ 968838032Speter by non-root users were not put into 968938032Speter X-Authentication-Warning:s as intended because the 969043730Speter config file hadn't set the PrivacyOptions yet. Fix 969138032Speter from Sven-Ove Westberg of the University of Lulea. 969238032Speter Under very odd circumstances, the alias file rebuild code 969338032Speter could get confused as to whether a database was 969438032Speter open or not. 969538032Speter Check "vendor code" on the end of V lines -- this is 969638032Speter intended to provide a hook for vendor-specific 969738032Speter configuration syntax. (This is a "new feature", 969838032Speter but I've made an exception to my rule in a belief 969938032Speter that this is a highly exceptional case.) 970038032Speter Portability fixes for DG/UX (from Douglas Anderson of NCSC), 970138032Speter SCO Unix (from Murray Kucherawy), A/UX, and OSF/1 970238032Speter (from Jon Forrest of UC Berkeley) 970338032Speter CONFIG: fix ``mailer:host'' form of UUCP relay naming. 970438032Speter 970564562Sgshapiro8.6.1/8.6 1993/10/08 970638032Speter Portability fixes for A/UX and Encore UMAX V. 970738032Speter Fix error message handling -- if you had a name server down 970838032Speter causing an error during parsing, that message was never 970938032Speter propagated to the queue file. 971038032Speter 971164562Sgshapiro8.6/8.6 1993/10/05 971238032Speter Configuration cleanup: make it easier to undo IDENTPROTO in 971338032Speter conf.h (other systems have the same bug). 971438032Speter If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume 971538032Speter getdtablesize() instead of sysconf(); a disturbingly 971638032Speter large number of systems defined _SC_OPEN_MAX in the 971738032Speter header files but don't have the syscall. 971838032Speter Another patch to really truly ignore MX records in getcanonname 971938032Speter if trymx == FALSE. 972038032Speter Fix problem that caused the "250 IAA25499 Message accepted for 972138032Speter delivery" message to be omitted if there was an error 972238032Speter in the header of the message (e.g., a bad Errors-To: 972338032Speter line). Pointed out by Michael Corrigan of UCSD. 972438032Speter Announce name of host we are chatting when we get errors; this 972538032Speter is an IDA-ism suggested by Christophe Wolfhugel. 972638032Speter Portability fixes for Alpha OSF/1 (from Anthony Baxter of the 972738032Speter Australian Artificial Intelligence Institute), SCO Unix 972838032Speter (from Murray Kucherawy of Hookup Communication Corp.), 972938032Speter NeXT (from Vince DeMarco and myself), Linux (from 973038032Speter Karl London <karl@borg.demon.co.uk>), BSDI (from 973138032Speter Christophe Wolfhugel, and SVR4 on Dell (from Kimmo 973238032Speter Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. 973338032Speter Some changes to get around gcc optimizer bugs. From Takahiro 973438032Speter Kanbe. 973538032Speter Fix error recovery in queueup if another tf file of the same 973638032Speter name already exists. Problem stumbled over by Bill 973738032Speter Wisner of The Well. 973838032Speter Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. 973938032Speter Problem noted by Keith McMillan of Ameritech Services. 974038032Speter Deal with group permissions properly when opening .forward and 974138032Speter :include: files. This relaxes the 8.1C restrictions 974238032Speter slightly more. This includes proper setting of groups 974338032Speter when reading :include: files, allowing you to read some 974438032Speter files that you should be able to read but have previously 974538032Speter been denied unless you owned them or they had "other" 974638032Speter read permission. 974738032Speter Make certain that $j is in $=w (after the .cf is read) so that 974838032Speter if the user is forced to override some silly system, 974938032Speter MX suppression will still work. 975038032Speter Fix a couple of efficiency problems where newstr was double- 975138032Speter calling expensive routines. In at least one case, it 975238032Speter wasn't guaranteed that they would always return the 975338032Speter same result. Problem noted by Christophe Wolfhugel. 975438032Speter Fix null pointer dereference in putoutmsg -- only on an error 975538032Speter condition from a non-SMTP mailer. From Motonori 975638032Speter Nakamura. 975738032Speter Macro expand "C" line class definitions before scanning so that 975838032Speter "CX $Z" works. 975938032Speter Fix problem that caused error message to be sent while still 976038032Speter trying to send the original message if the connection 976138032Speter is closed during a DATA command after getting an error 976238032Speter on an RCPT command (pretty obscure). Problem reported 976338032Speter by John Myers of CMU. 976438032Speter Fix reply to NOOP to be 250 instead of 200 -- this is a long 976538032Speter term bug. 976638032Speter Fix a nasty bug causing core dumps when returning the "warning: 976738032Speter cannot deliver for N hours -- will keep trying" message; 976843730Speter it only occurred if you had PostmasterCopy set and 976938032Speter only on some architectures. Although sendmail would 977038032Speter keep trying, it would send error messages on each 977138032Speter queue interval. This is an important fix. 977238032Speter Allow u and g options to take user and group names respectively. 977338032Speter Don't do a chdir into the queue directory in -bt mode to make 977438032Speter ruleset testing a bit easier. 977538032Speter Don't allow users to turn off logging (using -oL) on the command 977638032Speter line -- command line can only raise, not lower, logging 977738032Speter level. 977838032Speter Set $u to the original recipient on the SMTP transaction or on 977938032Speter the command line. This is only done if there is exactly 978038032Speter one recipient. Technically, this does not meet the 978138032Speter specs, because it does not guarantee a domain on the 978238032Speter address. 978338032Speter Fix a problem that dumped error messages on bad addresses if 978438032Speter you used the -t flag. Problem noted by Josh Smith of 978538032Speter Harvey Mudd College. 978638032Speter Given an address such as ``<foo> <bar>'', auto-quote the first 978738032Speter ``<foo>'' part, giving ``"<foo>" <bar>''. This is to 978838032Speter avoid the problem of people who use angle brackets in 978938032Speter their full name information. 979038032Speter Fix a null pointer dereference if you set option "l", have 979138032Speter an Errors-To: header in the message, and have Errors-To: 979238032Speter defined in the config file H lines. From J.R. Oldroyd. 979338032Speter Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get 979438032Speter wrong when compiling. Suggested by Rick McCarty of TI. 979538032Speter Fix a problem that could pass negative SIZE parameter if the 979638032Speter df file got lost; this would cause servers to always 979738032Speter give a temporary failure, making the problem even worse. 979838032Speter Problem noted by Allan Johannesen of WPI. 979938032Speter Add "ident" timeout (one of the "r" option selectors) for IDENT 980038032Speter protocol timeouts (30s default). Requested by Murray 980138032Speter Kucherawy of HookUp Communication Corp. to handle bogus 980238032Speter PC TCP/IP implementations. 980338032Speter Change $w default definition to be just the first component of 980438032Speter the domain name on config level 5. The $j macro defaults 980538032Speter to the FQDN; $m remains as before. This lets well-behaved 980638032Speter config files use any of the short, long, or subdomain 980738032Speter names. 980838032Speter Add makesendmail script in src to try to automate multi-architecture 980938032Speter builds. I know, this is sub-optimal, but it is still 981038032Speter helpful. 981138032Speter Fix very obscure race condition that can cause a queue run to 981238032Speter get a queue file for an already completed job. This 981338032Speter problem has existed for years. Problem noted by the 981438032Speter long suffering Allan Johannesen of WPI. 981538032Speter Fix a problem that caused the raw sender name to be passed to 981638032Speter udbsender instead of the canonified name -- this caused 981738032Speter it to sometimes miss records that it should have found. 981838032Speter Relax check of name on HELO packet so that a program using -bs 981938032Speter that claims to be itself works properly. 982038032Speter Restore rewriting of $: part of address through 2, R, 4 in 982138032Speter buildaddr -- this requires passing a lot of flags to get 982238032Speter it right. Unlike old versions, this ONLY rewrites 982338032Speter recipient addresses, not sender addresses. 982438032Speter Fix a bug that caused core dumps in config files that cannot 982538032Speter resolve /file/name style addresses. Fix from Jonathan 982638032Speter Kamens of OpenVision Technologies. 982738032Speter Fix problem with fcntl locking that can cause error returns to 982838032Speter be lost if the lock is lost; this required fully 982938032Speter queueing everything, dropping the envelope (so errors 983038032Speter would get returned), and then re-reading the queue from 983138032Speter scratch. 983238032Speter Fix a problem that caused aliases that redefine an otherwise 983338032Speter true address to still send to the original address 983438032Speter if and only if the alias failed in certain bizarre 983538032Speter ways (e.g, if they pointed at a list:; syntax address). 983638032Speter Problem pointed out by Jonathan Kamens. 983738032Speter Remove support for frozen configuration files. They caused 983838032Speter more trouble than it was worth. 983938032Speter Fix problem that can cause error messages to get ignored when 984038032Speter using both -odb and -t flags. Problem noted by Rob 984138032Speter McNicholas at U.C. Berkeley. 984238032Speter Include all "normal" variations on hostname in $=w. For example, 984338032Speter if the host name is vangogh.cs.berkeley.edu, $=w will 984438032Speter contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. 984538032Speter Add "restrictqrun" privacy flag -- without this, anyone can run 984638032Speter the queue. 984738032Speter Reset SmtpPhase global on initial connection creation so that 984838032Speter messages don't come out with stale information. 984938032Speter Pass an "ext" argument to lockfile so that error/log messages 985038032Speter will properly reflect the true filename being locked. 985138032Speter Put all [...] address forms into $=w -- this eliminates the need 985238032Speter for MAXIPADDR in conf.h. Suggested by John Gardiner 985338032Speter Myers of CMU. 985438032Speter Fix a bug that can cause qf files to be left around even after 985538032Speter an SMTP RSET command. Problem and fix from Michael 985638032Speter Corrigan. 985743730Speter Don't send a PostmasterCopy to errors when the Precedence: is 985838032Speter negative. Error reports still go to the envelope 985938032Speter sender address. 986038032Speter Add LA_SHORT for load averages. 986138032Speter Lock sendmail.st file when posting statistics. 986238032Speter Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to 986338032Speter set the size of the TCP send and receive buffers; if you 986438032Speter run over a slow slip line you may need to set these down 986538032Speter (although it would be better to fix the SLIP implementation 986638032Speter so that it's not necessary to recompile every program 986738032Speter that does bulk data transfer). 986838032Speter Allow null defaults on $( ... $) lookups. Problem reported by 986938032Speter Amir Plivatsky. 987038032Speter Diagnose crufty S and V config lines. This resulted from an 987138032Speter observation that some people were using the SITE macro 987238032Speter without the SITECONFIG macro first, which was causing 987338032Speter bogus config files that were not caught. 987438032Speter Fix makemap -f flag to turn off case folding (it was turning it 987538032Speter on instead). THIS IS A USER VISIBLE CHANGE!!! 987638032Speter Fix a problem that caused multiple error messages to be sent if 987738032Speter you used "sendmail -t -oem -odb", your system uses fcntl 987838032Speter locking, and one of the recipient addresses is unknown. 987938032Speter Reset uid earlier in include() so that recursive .forwards or 988038032Speter :include:s don't use the wrong uid. 988138032Speter If file descriptor 0, 1, or 2 was closed when sendmail was 988238032Speter called, the code to recover the descriptor was broken. 988338032Speter This sometimes (only sometimes) caused problems with the 988438032Speter alias file. Fix from Motonori Nakamura. 988538032Speter Fix a problem that caused aliaswait to go into infinite recursion 988638032Speter if the @:@ metasymbol wasn't found in the alias file. 988738032Speter Improve error message on newaliases if database files cannot be 988838032Speter opened or if running with no database format defined. 988938032Speter Do a better estimation of the size of error messages when NoReturn 989038032Speter is set. Problem noted by P{r (Pell) Emanuelsson. 989138032Speter Fix a problem causing the "c" option (don't connect to expensive 989238032Speter mailers) to be ignored in SMTP. Problem noted and the 989338032Speter solution suggested by Robert Elz of The University of 989438032Speter Melbourne. 989538032Speter Improve connection caching algorithm by passing "[host]" to 989638032Speter hostsignature, which strips the square brackets and 989738032Speter returns the real name. This allows mailertable entries 989838032Speter to match regular entries. 989938032Speter Re-enable Return-Receipt-To: -- people seem to want this stupid 990038032Speter feature, even if it doesn't work right. 990138032Speter Catch and log attempts to try the "wiz" command in server SMTP. 990238032Speter This also ups the log level from LOG_NOTICE to LOG_CRIT. 990338032Speter Be more generous at assigning $z to the home directory -- do this 990438032Speter for programs that are specified through a .forward file. 990538032Speter Fix from Andrew Chang of Sun Microsystems. 990638032Speter Always save a fatal error message in preference to a non-fatal 990738032Speter error message so that the "subject" line of return 990838032Speter messages is the best possible. 990938032Speter CONFIG: reduce the number of quotes needed to quote configuration 991038032Speter parameters with commas: two quotes should work now, e.g., 991138032Speter define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). 991238032Speter CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom 991338032Speter connections (domain-ized UUCP). 991438032Speter CONFIG: fix bug in default maps (-o must be before database file 991564562Sgshapiro name). Pointed out by Christophe Wolfhugel. 991638032Speter CONFIG: add FEATURE(nodns) to state that we are not relying on 991738032Speter DNS. This would presumably be used in UUCP islands. 991838032Speter CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). 991938032Speter CONFIG: log $u in Received: line. This is in technical violation 992038032Speter of the standards, since it doesn't guarantee a domain 992138032Speter on the address. 992238032Speter CONFIG: don't assume "m" in local mailer flags -- this means that 992338032Speter if you redefine LOCAL_MAILER_FLAGS you will have to include 992438032Speter the "m" flag should you want it. Apparently some Solaris 2.2 992538032Speter installations can't handle multiple local recipients. 992638032Speter Problem noted by Josh Smith. 992738032Speter CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). 992838032Speter CONFIG: change default version level from 4 to 5. 992938032Speter CONFIG: add FEATURE(nullclient) to create a config file that 993038032Speter forwards all mail to a hub without ever looking at the 993138032Speter addresses in any detail. 993238032Speter CONFIG: properly strip mailer: information off of relays when 993338032Speter used to change .BITNET form into %-hack form. 993438032Speter CONFIG: fix a problem that caused infinite loops if presented 993538032Speter with an address such as "!foo". 993638032Speter CONFIG: check for self literal (e.g., [128.32.131.12]) even if 993738032Speter the reverse "PTR" mapping is broken. There's a better 993838032Speter way to do this, but the change is fairly major and I 993938032Speter want to hold it for another release. Problem noted by 994038032Speter Bret Marquis. 994138032Speter 994264562Sgshapiro8.5/8.5 1993/07/23 994338032Speter Serious bug: if you used a command line recipient that was unknown 994438032Speter sendmail would not send a return message (it was treating 994538032Speter everything as though it had an SMTP-style client that 994638032Speter would do the return itself). Problem noted by Josh Smith. 994738032Speter Change "trymx" option in getcanonname() to ignore all MX data, 994838032Speter even during a T_ANY query. This actually didn't break 994938032Speter anything, because the only time you called getcanonname 995038032Speter with !trymx was if you already knew there were no MX 995138032Speter records, but it is somewhat cleaner. From Motonori 995238032Speter Nakamura. 995338032Speter Don't call getcanonname from getmxrr if you already know there 995438032Speter are no DNS records matching the name. 995538032Speter Fix a problem causing error messages to always include "The 995638032Speter original message was received ... from localhost". 995738032Speter The correct original host information is now included. 995838032Speter Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their 995938032Speter version of "test" doesn't have the -x flag). Change it 996038032Speter to use -f instead. From John Myers. 996138032Speter CONFIG: 8.4 mistakenly set the default SMTP-style mailer to 996238032Speter esmtp -- it should be smtp. 996338032Speter CONFIG: send all relayed mail using confRELAY_MAILER (defaults 996438032Speter to "relay" (a variant of "smtp") if MAILER(smtp) is used, 996538032Speter else "suucp" if MAILER(uucp) is used, else "unknown"); 996638032Speter this cleans up the configs somewhat. This fixes a serious 996738032Speter problem that caused route-addrs to get mistaken as relays, 996838032Speter pointed out by John Myers. WARNING: this also causes 996938032Speter the default on SMART_HOST to change from "suucp" to 997038032Speter "relay" if you have MAILER(smtp) specified. 997138032Speter 997264562Sgshapiro8.4/8.4 1993/07/22 997338032Speter Add option `w'. If you receive a message that comes to you because 997438032Speter you are the best (lowest preference) target of an MX, and 997538032Speter you haven't explicitly recognized the source MX host in 997638032Speter your .cf file, this option will cause you to try the target 997738032Speter host directly (as if there were no MX for it at all). If 997838032Speter `w' is not set, this case is a configuration error. 997938032Speter Beware: if `w' is set, senders may get bogus errors like 998038032Speter "message timed out" or "host unknown" for problems that 998138032Speter are really configuration errors. This option is 998238032Speter disrecommended, provided only for compatibility with 998338032Speter UIUC sendmail. 998438032Speter Fix a problem that caused the incoming socket to be left open 998538032Speter when sendmail forks after the DATA command. This caused 998638032Speter calling systems to wait in FIN_WAIT_2 state until the 998738032Speter entire list was processed and the child closed -- a 998838032Speter potentially prodigious amount of time. Problem noted 998938032Speter by Neil Rickert. 999038032Speter Fix problem (created in 6.64) that caused mail sent to multiple 999138032Speter addresses, one of which was a bad address, to completely 999238032Speter suppress the sending of the message. This changes 999338032Speter handling of EF_FATALERRS somewhat, and adds an 999438032Speter EF_GLOBALERRS flag. This also fixes a potential problem 999538032Speter with duplicate error messages if there is a syntax error 999638032Speter in the header of a message that isn't noticed until late 999738032Speter in processing. Original problem pointed out by Josh Smith 999838032Speter of Harvey Mudd College. This release includes quite a bit 999938032Speter of dickering with error handling (see below). 1000038032Speter Back out SMTP transaction if MAIL gets nested 501 error. This 1000138032Speter will only hurt already-broken software and should help 1000238032Speter humans. 1000338032Speter Fix a problem that broke aliases when neither NDBM nor NEWDB were 1000438032Speter compiled in. It would never read the alias file. 1000538032Speter Repair unbalanced `)' and `>' (the "open" versions are already 1000638032Speter repaired). 1000738032Speter Logging of "done" in dropenvelope() was incorrect: it would 1000838032Speter log this even when the queue file still existed. Change 1000938032Speter this to only log "done" (at log level 11) when the 1001038032Speter queue file is actually removed. From John Myers. 1001138032Speter Log "lost connection" in server SMTP at log level 20 if there 1001238032Speter is no pending transaction. Some senders just close the 1001338032Speter connection rather than sending QUIT. 1001438032Speter Fix a bug causing getmxrr to add a dot to the end of unqualified 1001538032Speter domains that do not have MX records -- this would cause 1001638032Speter the subsequent host name lookup to fail. The problem 1001738032Speter only occurred if you had FEATURE(nocanonify) set. 1001838032Speter Problem noted by Rick McCarty of Texas Instruments. 1001938032Speter Fix invocation of setvbuf when passed a -X flag -- I had 1002038032Speter unwittingly used an ANSI C extension, and this caused 1002138032Speter core dumps on some machines. 1002238032Speter Diagnose self-destructive alias loops on RCPT as well as EXPN. 1002338032Speter Previously it just gave an empty send queue, which 1002438032Speter then gave either "Need RCPT (recipient)" at the DATA 1002538032Speter (confusing, since you had given an RCPT command which 1002638032Speter returned 250) or just dropped the email, depending on 1002738032Speter whether you were running VERBose mode. Now it usually 1002838032Speter diagnoses this case as "aliasing/forwarding loop broken". 1002938032Speter Unfortunately, it still doesn't adequately diagnose 1003038032Speter some true error conditions. 1003138032Speter Add internal concept of "warning messages" using 6xx codes. 1003238032Speter These are not reported only to Postmaster. Unbalanced 1003338032Speter parens, brackets, and quotes are printed as 653 codes. 1003438032Speter They are always mapped to 5xx codes before use in SMTP. 1003538032Speter Clean up error messages to tell both the actual address that 1003638032Speter failed and the alias they arose from. This makes it 1003738032Speter somewhat easier to diagnose problems. Difficulty noted 1003838032Speter by Motonori Nakamura. 1003938032Speter Fix a problem that inappropriately added a ctladdr to addresses 1004038032Speter that shouldn't have had one during a queue run. This 1004138032Speter caused error messages to be handled differently during 1004238032Speter a queue run than a direct run. 1004338032Speter Don't print the qf name and line number if you get errors during 1004438032Speter the direct run of the queue from srvrsmtp -- this was 1004538032Speter just extra stuff for users to crawl through. 1004638032Speter Put command line flags on second line of pid file so you can 1004738032Speter auto-restart the daemon with all appropriate arguments. 1004838032Speter Use "kill `head -1 /etc/sendmail.pid`" to stop the 1004938032Speter daemon, and "eval `tail -1 /etc/sendmail.pid`" to 1005038032Speter restart it. 1005138032Speter Remove the ``setuid(getuid())'' in main -- this caused the 1005238032Speter IDENT daemon to screw up. This required that I change 1005338032Speter HASSETEUID to HASSETREUID and complicate the mode 1005438032Speter changing somewhat because both Ultrix and SunOS seem 1005538032Speter to have a bug causing seteuid() to set the saved uid 1005638032Speter as well as the effective. The program test/t_setreuid.c 1005738032Speter will test to see if your implementation of setreuid(2) 1005838032Speter is appropriately functional. 1005938032Speter The FallBackMX (option V) handling failed to properly identify 1006038032Speter fallback to yourself -- most of the code was there, 1006138032Speter but it wasn't being enabled. Problem noted by Murray 1006238032Speter Kucherawy of the University of Waterloo. 1006338032Speter Change :include: open timeout from ETIMEDOUT to an internal 1006438032Speter code EOPENTIMEOUT; this avoids adding "during SmtpPhase 1006538032Speter with CurHostName" in error messages, which can be 1006638032Speter confusing. Reported by Jonathan Kamens of OpenVision 1006738032Speter Technologies. 1006838032Speter Back out setpgrp (setpgid on POSIX systems) call to reset the 1006938032Speter process group id. The original fix was to get around 1007038032Speter some problems with recalcitrant MUAs, but it breaks 1007138032Speter any call from a shell that creates a process group id 1007238032Speter different from the process id. I could try to fix 1007338032Speter this by diddling the tty owner (using tcsetpgrp or 1007438032Speter equivalent) but this is too likely to break other 1007538032Speter things. 1007638032Speter Portability changes: 1007738032Speter Support -M as equivalent to -oM on Ultrix -- apparently 1007838032Speter DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs 1007938032Speter instead of using standard flags. Oh joy. This 1008043730Speter behavior reported by Jon Giltner of University 1008138032Speter of Colorado. 1008238032Speter SGI IRIX -- this includes several changes that should 1008338032Speter help other strict ANSI compilers. 1008438032Speter SCO Unix -- from Murray Kucherawy of HookUp Communication 1008538032Speter Corporation. 1008638032Speter Solaris running the Sun C compiler (which despite the 1008738032Speter documentation apparently doesn't define 1008838032Speter __STDC__ by default). 1008938032Speter ConvexOS from Eric Schnoebelen of Convex. 1009038032Speter Sony NEWS workstations and Omron LUNA workstations from 1009138032Speter Motonori Nakamura. 1009238032Speter CONFIG: add confTRY_NULL_MX_LIST to set option `w'. 1009338032Speter CONFIG: delete `C' and `e' from default SMTP mailers flags; 1009438032Speter several people have made a good argument that this 1009538032Speter creates more problems than it solves (although this 1009638032Speter may prove painful in the short run). 1009738032Speter CONFIG: generalize all the relays to accept a "mailer:host" 1009838032Speter format. 1009938032Speter CONFIG: move local processing in ruleset 0 into a new ruleset 1010038032Speter 98 (8 on old sendmail). Domain literal [a.b.c.d] 1010138032Speter addresses are also passed through this ruleset. 1010238032Speter CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, 1010338032Speter internet-style addresses would "fall off the end" of 1010438032Speter ruleset zero and be interpreted as local -- however, 1010538032Speter the angle brackets confused the recursive call. 1010638032Speter These are now diagnosed as "Unrecognized host name". 1010738032Speter CONFIG: USENET rules weren't included in S0 because of a mistaken 1010838032Speter ifdef(`_MAILER_USENET_') instead of 1010938032Speter ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik 1011038032Speter of SINTEF RUNIT, Oslo. 1011138032Speter CONFIG: move up LOCAL_RULE_0 processing so that it happens very 1011238032Speter early in ruleset 0; this allows .mc authors to bypass 1011338032Speter things like the "short circuit" code for local addresses. 1011438032Speter Prompted by a comment by Bill Wisner of The Well. 1011538032Speter CONFIG: add confSMTP_MAILER to define the mailer used (smtp or 1011638032Speter esmtp) to send SMTP mail. This allows you to default 1011738032Speter to esmtp but use a mailertable or other override to 1011838032Speter deal with broken servers. This logic was pointed out 1011938032Speter to me by Bill Wisner. Ditto for confLOCAL_MAILER. 1012038032Speter Changes to cf/sh/makeinfo.sh to make it portable to SVR4 1012138032Speter environments. Ugly as sin. 1012238032Speter 1012364562Sgshapiro8.3/8.3 1993/07/13 1012438032Speter Fix setuid problems introduced in 8.2 that caused messages 1012538032Speter like "Cannot create qfXXXXXX: Invalid argument" 1012638032Speter or "Cannot reopen dfXXXXXX: Permission denied". This 1012738032Speter involved a new compile flag "HASSETEUID" that takes 1012838032Speter the place of the old _POSIX_SAVED_IDS -- it turns out 1012938032Speter that the POSIX interface is broken enough to break 1013038032Speter some systems badly. This includes some fixes for 1013138032Speter HP-UX. Also fixes problems where the real uid is 1013238032Speter not reset properly on startup (from Neil Rickert). 1013338032Speter Fix a problem that caused timed out messages to not report the 1013438032Speter addresses that timed out. Error messages are also more 1013538032Speter "user friendly". 1013638032Speter Drop required bandwidth on connections from 64 bytes/sec to 1013738032Speter 16 bytes/sec. 1013838032Speter Further Solaris portability changes -- doesn't require the BSD 1013938032Speter compatibility library. This also adds a new 1014038032Speter "HASGETDTABLESIZE" compile flag which can be used if 1014138032Speter you want to use getdtablesize(2) instead of sysconf(2). 1014238032Speter These are loosely based on changes from David Meyer at 1014338032Speter University of Oregon. This now seems to work, at least 1014438032Speter for quick test cases. 1014538032Speter Fix a problem that can cause duplicate error messages to be 1014638032Speter sent if you are in SMTP, you send to multiple addresses, 1014738032Speter and at least one of those addresses is good and points 1014838032Speter to an account that has a .forward file (whew!). 1014938032Speter Fix a problem causing messages to be discarded if checkcompat() 1015038032Speter returned EX_TEMPFAIL (because it didn't properly mark 1015138032Speter the "to" address). Problem noted by John Myers. 1015238032Speter Fix dfopen to return NULL if the open failed; I was depending 1015338032Speter on fdopen(-1) returning NULL, which isn't the case. This 1015438032Speter isn't serious, but does result in weird error diagnoses. 1015538032Speter From Michael Corrigan. 1015638032Speter CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of 1015738032Speter messages sent through UUCP-family mailers. Suggested 1015838032Speter by Bill Wisner of The Well. 1015938032Speter CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, 1016038032Speter include a "uucp-dom" mailer that uses domain-style 1016138032Speter addressing. Suggested by Bill Wisner. 1016238032Speter CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match 1016338032Speter LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by 1016438032Speter Christophe Wolfhugel. 1016538032Speter CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. 1016638032Speter 1016764562Sgshapiro8.2/8.2 1993/07/11 1016838032Speter Don't drop out on config file parse errors in -bt mode. 1016938032Speter On older configuration files, assume option "l" (use Errors-To 1017038032Speter header) for back compatibility. NOTE: this DOES NOT 1017138032Speter imply an endorsement of the Errors-To: header in any way. 1017238032Speter Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? 1017338032Speter Don't log errors on EHLO -- it isn't a "real" error for an old 1017438032Speter SMTP server to give an error on this command, and 1017538032Speter logging it in the transcript can be confusing. Fix 1017638032Speter from Bill Wisner. 1017738032Speter IRIX compatibility changes provided by Dan Rich 1017838032Speter <drich@sandman.lerc.nasa.gov>. 1017938032Speter Solaris 2 compatibility changes. Provided by Bob Cunningham 1018038032Speter <bob@kahala.soest.hawaii.edu>, John Oleynick 1018138032Speter <juo@klinzhai.rutgers.edu> 1018238032Speter Debugging: -d17 was overloaded (hostsignature and usersmtp.c); 1018338032Speter move usersmtp (smtpinit and smtpmailfrom) to -d18 to 1018438032Speter match the other flags in that file. 1018538032Speter Flush transcript before fork in mailfile(). From Eric Wassenaar. 1018638032Speter Save h_errno in mci struct and improve error message display. 1018738032Speter Changes from Eric Wassenaar. 1018838032Speter Open /dev/null for the transcript if the create of the xf file 1018938032Speter failed; this avoids at least one possible null pointer 1019038032Speter reference in very weird cases. From Eric Wassenaar. 1019138032Speter Clean up statistics gathering; it was over-reporting because of 1019238032Speter forks. From Eric Wassenaar. 1019338032Speter Fix problem that causes old Return-Path: line to override new 1019438032Speter Return-Path: line (conf.c needs H_FORCE to avoid 1019538032Speter re-using old value). From Motonori Nakamura. 1019638032Speter Fix broken -m flag in K definition -- even if -m (match only) 1019738032Speter was specified, it would still replace the key with the 1019838032Speter value. Noted by Rick McCarty of Texas Instruments. 1019938032Speter If the name server timed out over several days, no "timed out" 1020038032Speter message would ever be sent back. The timeout code 1020138032Speter has been moved from markfailure() to dropenvelope() 1020238032Speter so that all such failures should be diagnosed. Pointed 1020338032Speter out by Christophe Wolfhugel and others. 1020438032Speter Relax safefile() constraints: directories in an include or 1020538032Speter forward path must be readable by self if the controlling 1020638032Speter user owns the entry, readable by all otherwise (e.g., 1020738032Speter when reading your .forward file, you have to own and 1020838032Speter have X permission in it; everyone needs X permission in 1020938032Speter the root and directories leading up to your home); 1021038032Speter include files must be readable by anyone, but need not 1021138032Speter be owned by you. 1021238032Speter If _POSIX_SAVED_IDS is defined, setuid to the owner before 1021338032Speter reading a .forward file; this gets around some problems 1021438032Speter on NFS mounts if root permission is not exported and 1021538032Speter the user's home directory isn't x'able. 1021638032Speter Additional NeXT portability enhancements from Axel Zinser. 1021738032Speter Additional HP-UX portability enhancements from Brian Bullen. 1021838032Speter Add a timeout around SMTP message writes; this assumes you can 1021938032Speter get throughput of at least 64 bytes/second. Note that 1022038032Speter this does not impact the "datafinal" default, which 1022138032Speter is separate; this is just intended to work around 1022238032Speter network clogs that will occur before the final dot 1022338032Speter is sent. From Eric Wassenaar. 1022438032Speter Change map code to set the "include null" flag adaptively -- 1022538032Speter it initially tries both, but if it finds anything 1022638032Speter matching without a null it never tries again with a 1022738032Speter null and vice versa. If -N is specified, it never 1022838032Speter tries without the null and creates new maps with a 1022938032Speter null byte. If -O is specified, it never tries with 1023038032Speter the null (for efficiency). If -N and -O are specified, 1023138032Speter you get -NO (get it?) lookup at all, so this would 1023238032Speter be a bad idea. If you don't specify either -N or -O, 1023338032Speter it adapts. 1023438032Speter Fix recognition of "same from address" so that MH submissions 1023538032Speter will insert the appropriate full name information; 1023638032Speter this used to work and got broken somewhere along the 1023738032Speter way. 1023838032Speter Some changes to eliminate some unnecessary SYSERRs in the 1023938032Speter log. For example, if you lost a connection, don't 1024038032Speter bother reporting that fact on the connection you lost. 1024138032Speter Add some "extended debugging" flags to try to track down 1024238032Speter why we get occasional problems with file descriptor 1024338032Speter one being closed when execing a mailer; it seems to 1024438032Speter only happen when there has been another error in the 1024538032Speter same transaction. This requires XDEBUG, defined 1024638032Speter by default in conf.h. 1024738032Speter Add "-X filename" command line flag, which logs both sides of 1024838032Speter all SMTP transactions. This is intended ONLY for 1024938032Speter debugging bad implementations of other mailers; start 1025038032Speter it up, send a message from a mailer that is failing, 1025138032Speter and then kill it off and examine the indicated log. 1025238032Speter This output is not intended to be particularly human 1025338032Speter readable. This also adds the HASSETVBUF compile 1025438032Speter flag, defaulted on if your compiler defines __STDC__. 1025538032Speter CONFIG: change SMART_HOST to override an SMTP mailer. If you 1025638032Speter have a local net that should get direct connects, you 1025738032Speter will need to use LOCAL_NET_CONFIG to catch these hosts. 1025838032Speter See cf/README for an example. 1025938032Speter CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle 1026038032Speter sites that don't use the -d flag. 1026138032Speter CONFIG: hide recipient addresses as well as sender addresses 1026238032Speter behind $M if FEATURE(allmasquerade) is specified; this 1026338032Speter has been requested by several people, but can break 1026438032Speter local aliases. For example, if you mail to "localalias" 1026538032Speter this will be rewritten as "localalias@masqueradehost"; 1026638032Speter although initial delivery will work, replies will be 1026738032Speter broken. Use it sparingly. 1026838032Speter CONFIG: add FEATURE(domaintable). This maps unqualified domains 1026938032Speter to qualified domains in headers. I believe this is 1027038032Speter largely equivalent to the IDA feature of the same name. 1027138032Speter CONFIG: use $U as UUCP name instead of $k. This permits you 1027238032Speter to override the "system name" as your UUCP name -- 1027338032Speter in particular, to use domain-ized UUCP names. From 1027438032Speter Bill Wisner of The Well. 1027538032Speter CONFIG: create new mailer "esmtp" that always tries EHLO 1027638032Speter first. This is currently unused in the config files, 1027738032Speter but could be used in a mailertable entry. 1027838032Speter 1027964562Sgshapiro8.1C/8.1B 1993/06/27 1028038032Speter Serious security bug fix: it was possible to read any file on 1028138032Speter the system, regardless of ownership and permissions. 1028238032Speter If a subroutine returns a fully qualified address, return it 1028338032Speter immediately instead of feeding it back into rewriting. 1028438032Speter This fixes a problem with mailertable lookups. 1028538032Speter CONFIG: fix some M4 frotz (concat => CONCAT) 1028638032Speter 1028764562Sgshapiro8.1B/8.1A 1993/06/12 1028838032Speter Serious bug fix: pattern matching backup algorithm stepped by 1028938032Speter two tokens in classes instead of one.
