Change log file for Exim from version 4.21
-------------------------------------------
+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.
+
Exim version 4.52
-----------------
PH/15 The code I had for printing potentially long long variables in PH/11
above was not the best (it lost precision). The length of off_t variables
is now inspected at build time, and an appropriate printing format (%ld
- or %lld) is chosen and #defined by OFF_T_FMT. We also define ASSUME_
- LONG_LONG_SUPPORT if the length is greater than 4. This is needed for the
- internal formatting function string_vformat().
+ or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
+ to be "long long int" or "long int". This is needed for the internal
+ formatting function string_vformat().
PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
the configuration file to be ":syslog", then the script "guesses" where
with no configuration file to get the compiled in version, before it
falls back to the previous guessing code."
+TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with
+ implementing BATV in an Exim configuration. See NewStuff for the gory
+ details.
+
+PH/17 Applied Michael Haardt's patch for HP-UX, affecting only the os.h and
+ Makefile that are specific to HP-UX.
+
+PH/18 If the "use_postmaster" option was set for a recipient callout together
+ with the "random" option, the postmaster address was used as the MAIL
+ FROM address for the random test, but not for the subsequent recipient
+ test. It is now used for both.
+
+PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
+ patch removes a few documentation additions to RFC 3028, because the
+ latest draft now contains them. It adds the new en;ascii-case comparator
+ and a new error check for 8bit text in MIME parts. Comparator and
+ require names are now matched exactly. I enabled the subaddress
+ extension, but it is not well tested yet (read: it works for me)."
+
+PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
+ rework some of the code of TK/09 above to avoid the hardwired use of
+ "%lld" and "long long". Replaced the call to snprintf() with a call to
+ string_vformat().
+
+PH/21 Added some other messages to those in 4.51/PH/42, namely "All relevant MX
+ records point to non-existent hosts", "retry timeout exceeded", and
+ "retry time not reached for any host after a long failure period".
+
+PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
+ experimental DomainKeys support:
+
+ (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
+ (2) On an error such as an illegally used "control", the wrong name for
+ the control was given.
+
+ These problems did NOT occur unless DomainKeys support was compiled.
+
+PH/23 Added daemon_startup_retries and daemon_startup_sleep.
+
+PH/24 Added ${if match_ip condition.
+
+PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
+ databases so that it will be absolutely obvious if a crash occurs in the
+ DB library. This is a regular occurrence (often caused by mis-matched
+ db.h files).
+
+PH/26 Insert a lot of missing (void) casts for functions such as chown(),
+ chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
+ picked up on a user's system that detects such things. There doesn't seem
+ to be a gcc warning option for this - only an attribute that has to be
+ put on the function's prototype. It seems that in Fedora Core 4 they have
+ set this on a number of new functions. No doubt there will be more in due
+ course.
+
+PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
+ specify a transport. However, if an address that was verified by such a
+ router was the subject of a callout, Exim crashed because it tried to
+ read the rcpt_include_affixes from the non-existent transport. Now it
+ just assumes that the setting of that option is false. This bug was
+ introduced by 4.51/PH/31.
+
+PH/28 Changed -d+all to exclude +memory, because that information is very
+ rarely of interest, but it makes the output a lot bigger. People tend to
+ do -d+all out of habit.
+
+PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the
+ code in os-type was giving problems when libc.so lives in lib64, like on
+ x86_64 Fedora Core.
+
+PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
+ aren't the modern standard, and it seems that some systems' include files
+ don't always have them. Exim was already checking for some of the newer
+ ones like T_AAAA, and defining it itself. I've added checks for all the
+ record types that Exim uses.
+
+PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
+ not automatically generating a new one, as it is supposed to. This
+ prevented TLS from working. If the file did exist, but contained invalid
+ data, a new version was generated, as expected. It was only the case of a
+ non-existent file that was broken.
+
+TK/10 Domainkeys: Fix a bug in verification that caused a crash in conjunction
+ with a change in libdomainkeys > 0.64.
+
+TK/11 Domainkeys: Change the logic how the "testing" policy flag is retrieved
+ from DNS. If the selector record carries the flag, it now has
+ precedence over the domain-wide flag.
+
+TK/12 Cleared some compiler warnings related to SPF, SRS and DK code.
+
+PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
+ the use of a port name that isn't defined in /etc/services) occurred, the
+ message was deferred as in a normal delivery, and thus remained on the
+ spool, instead of being failed because of the mua_wrapper setting. This
+ is now fixed, and I tidied up some of the mua_wrapper messages at the
+ same time.
+
+SC/08 Eximstats: whilst parsing the mainlog(s), store information about
+ the messages in a hash of arrays rather than using individual hashes.
+ This is a bit cleaner and results in dramatic memory savings, albeit
+ at a slight CPU cost.
+
+SC/09 Eximstats: added the -show_rt<list> and the -show_dt<list> flags
+ as requested by Marc Sherman.
+
+SC/10 Eximstats: added histograms for user specified patterns as requested
+ by Marc Sherman.
+
+SC/11 Eximstats: v1.43 - bugfix for pattern histograms with -h0 specified.
+
+PH/33 Patch from the Cygwin maintainer to add "b" to all occurences of
+ fopen() in the content-scanning modules that did not already have it.
+
