I have changed it to + "/bin:/usr/bin". + +PH/04 SUPPORT_TRANSLATE_IP_ADDRESS and MOVE_FROZEN_MESSAGES did not cause + anything to be listed in the output from -bV. + + +Exim version 4.54 +----------------- + +PH/01 The ${base62: operator adjusted itself to base 36 when BASE_62 was + set to 36 (for Darwin and Cygwin), but the ${base62d: operator did not. + It now does. + +PH/02 Two minor problems detected in Cygwin: the os.{c,h} files had lost */ on + the CVS lines, and there was a missing #if HAVE_IPV6 in host.c. + +PH/03 Typo: missing ".o" in src/pcre/Makefile. + +PH/04 Tighten up "personal" tests: Instead of testing for any "List-" + header line, restrict the check to what is listed in RFCs 2369 and 2929. + Also, for "Auto-Submitted", treat anything other than "no" as + non-personal, in accordance with RFC 3834. (Previously it treated + anything starting "auto-" as non-personal.) + +TF/01 The control=submission/name=... option had a problem with syntax + errors if the name included a slash character. The /name= option + now slurps the rest of the string, so it can include any characters + but it must come last in the list of options (after /sender_retain + or /domain=). + +PH/05 Some modifications to the interface to the fake nameserver for the new + testing suite. + + +Exim version 4.53 +----------------- + +TK/01 Added the "success_on_redirect" address verification option. See + NewStuff for rationale and an example. + +PH/01 Added support for SQLite, basic code supplied by David Woodhouse. + +PH/02 Patch to exigrep to allow it to work on syslog lines. + +PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of + fread() to skip over the body file's header line, because in Cygwin the + header line is locked and is inaccessible. + +PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both + co-exist for some time) to make it clear that it is the Exim ID that is + referenced, not the Message-ID: header line. + +PH/05 Replaced all Tom's calls to snprintf() with calls to the internal + string_format() function, because snprintf() does not exist on all + operating systems. + +PH/06 The use of forbid_filter_existstest now also locks out the use of the + ${stat: expansion item. + +PH/07 Changed "SMTP protocol violation: synchronization error" into "SMTP + protocol synchronization error", to keep the pedants happy. + +PH/08 Arrange for USE_INET_NTOA_FIX to be set in config.h for AIX systems as + well as for IRIX systems, when gcc is being used. See the host.c source + file for comments. + +PH/09 Installed latest Cygwin configuration files from the Cygwin maintainer. + +PH/10 Named domain lists were not working if used in a queue_smtp_domains + setting. + +PH/11 Added support for the IGNOREQUOTA extension to LMTP, both to the lmtp + transport and to the smtp transport in LMTP mode. + +TK/02 Remove one case of BASE64 error detection FTTB (undocumented anyway). + +PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to + run a filter in a subprocess. This could lead to confusion in subsequent + lookups in the parent process. There should also be a search_tidyup() at + the end of the subprocess. + +PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true + only if the host matched helo_try_verify_hosts, which caused the + verification to occur when the EHLO/HELO command was issued. The ACL just + tested the remembered result. Now, if a previous verification attempt has + not happened, "verify = helo" does it there and then. + +JJ/01 exipick: added $message_exim_id variable (see 4.53-PH/04) + +TK/03 Fix log output including CR from clamd. + +PH/14 A reference to $reply_address when Reply-to: was empty and From: did not + exist provoked a memory error which could cause a segfault. + +PH/15 Installed PCRE 6.2 + +PH/17 Defined BIND_8_COMPAT in the Darwin os.h file. + +PH/18 Reversed 4.52/PH/17 because the HP-UX user found it wasn't the cause + of the problem. Specifically, suggested +O2 rather than +O1 for the + HP-UX compiler. + +PH/19 Added sqlite_lock_timeout option (David Woodhouse's patch). + +PH/20 If a delivery was routed to a non-standard port by means of an SRV + record, the port was not correctly logged when the outgoing_port log + selector was set (it logged the transort's default port). + +PH/21 Added support for host-specific ports to manualroute, queryprogram, + fallback_hosts, and "hosts" in the smtp transport. + +PH/22 If the log selector "outgoing_port" is set, the port is now also given on + host errors such as "Connection refused". + +PH/23 Applied a patch to fix problems with exim-4.52 while doing radius + authentication with radiusclient 0.4.9: + + - Error returned from rc_read_config was caught wrongly + - Username/password not passed on to radius server due to wrong length. + + The presumption is that some radiusclient API changes for 4.51/PH/17 + were not taken care of correctly. The code is still untested by me (my + Linux distribution still has 0.3.2 of radiusclient), but it was + contributed by a Radius user. + +PH/24 When doing a callout, the value of $domain wasn't set correctly when + expanding the "port" option of the smtp transport. + +TK/04 MIME ACL: Fix buffer underrun that occurs when EOF condition is met + while reading a MIME header. Thanks to Tom Hughes for a patch. + +PH/24 Include config.h inside local_scan.h so that configuration settings are + available. + +PH/25 Make $smtp_command_argument available after all SMTP commands. This means + that in an ACL for RCPT (for example), you can examine exactly what was + received. + +PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO + commands, but it was not correctly comparing the address with the actual + client host address. Thus, it would show the EHLO address in Received: + header lines when this was not necessary. + +PH/27 Added the % operator to ${eval:}. + +PH/28 Exim tries to create and chdir to its spool directory when it starts; + it should be ignoring failures (because with -C, for example, it has lost + privilege). It wasn't ignoring creation failures other than "already + exists". + +PH/29 Added "crypteq" to the list of supported features that Exim outputs when + -bV or -d is used. + +PH/30 Fixed (presumably very longstanding) bug in exim_dbmbuild: if it failed + because an input line was too long, either on its own, or by virtue of + too many continuations, the temporary file was not being removed, and the + return code was incorrect. + +PH/31 Missing "BOOL" in function definition in filtertest.c. + +PH/32 Applied Sieve patches from the maintainer. + +TK/05 Domainkeys: Accomodate for a minor API change in libdomainkeys 0.67. + +PH/33 Added "verify = not_blind". + +PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in + Local/Makefile (with some defaults set). These are used in built scripts + such as exicyclog, but they have never been used in the exim_install + script (though there are many overriding facilities there). I have + arranged that the exim_install script now takes note of these two + settings. + +PH/35 Installed configuration files for Dragonfly. + +PH/36 When a locally submitted message by a trusted user did not contain a + From: header, and the sender address was obtained from -f or from an SMTP + MAIL command, and the trusted user did not use -F to supply a sender + name, $originator_name was incorrectly used when constructing a From: + header. Furthermore, $originator_name was used for submission mode + messages from external hosts without From: headers in a similar way, + which is clearly wrong. + +PH/37 Added control=suppress_local_fixups. + +PH/38 When log_selector = +received_sender was set, and the addition of the + sender made the log line's construction buffer exactly full, or one byte + less than full, an overflow happened when the terminating "\n" was + subsequently added. + +PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry + when the result of a list match is failure because a DNS lookup failed. + +PH/40 RM_COMMAND is now used in the building process. + +PH/41 Added a "distclean" target to the top-level Makefile; it deletes all + the "build-* directories that it finds. + +PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP + address in a domain literal was a prefix of an interface address. + +PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains + when verifying a sender address, unless rewrite_headers is false. + +PH/44 Wrote a long comment about why errors_to addresses are verified as + recipients, not senders. + +TF/01 Add missing LIBS=-lm to OS/Makefile-OpenBSD which was overlooked when + the ratelimit ACL was added. + +PH/45 Added $smtp_command for the full command (cf $smtp_command_argument). + +PH/46 Added extra information about PostgreSQL errors to the error string. + +PH/47 Added an interface to a fake DNS resolver for use by the new test suite, + avoiding the need to install special zones in a real server. This is + backwards compatible; if it can't find the fake resolver, it drops back. + Thus, both old and new test suites can be run. + +TF/02 Added util/ratelimit.pl + +TF/03 Minor fix to the ratelimit code to improve its behaviour in case the + clock is set back in time. + +TF/04 Fix the ratelimit support in exim_fixdb. Patch provided by Brian + Candler . + +TF/05 The fix for PH/43 was not completely correct; widen_domains is always + OK for addresses that are the result of redirections. + +PH/48 A number of further additions for the benefit of the new test suite, + including a fake gethostbyname() that interfaces to the fake DNS resolver + (see PH/47 above). + +TF/06 The fix for widen_domains has also been applied to qualify_single and + search_parents which are the other dnslookup options that can cause + header rewrites. + +PH/49 Michael Haardt's randomized retrying, but as a separate retry parameter + type ("H"). + +PH/50 Make never_users, trusted_users, admin_groups, trusted_groups expandable. + +TF/07 Exim produced the error message "an SRV record indicated no SMTP + service" if it encountered an MX record with an empty target hostname. + The message is now "an MX or SRV record indicated no SMTP service". + +TF/08 Change PH/13 introduced the possibility that verify=helo may defer, + if the DNS of the sending site is misconfigured. This is quite a + common situation. This change restores the behaviour of treating a + helo verification defer as a failure. + +PH/51 If self=fail was set on a router, the bounce message did not include the + actual error message. + Exim version 4.52 ----------------- @@ -160,8 +448,9 @@ PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to "%lld" and "long long".
