See + doc/experimental-spec.txt for details. (http://domainkeys.sf.net) + +TK/02 Fix ACL "control" statment not being available in MIME ACL. + +TK/03 Fix ACL "regex" condition not being available in MIME ACL. + +PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used + to test Sieve filters that use "vacation". + +PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch + that changes the way the GnuTLS parameters are stored in the cache file. + The new format can be generated externally. For backward compatibility, + if the data in the cache doesn't make sense, Exim assumes it has read an + old-format file, and it generates new data and writes a new file. This + means that you can't go back to an older release without removing the + file. + +PH/03 A redirect router that has both "unseen" and "one_time" set does not + work if there are any delivery delays because "one_time" forces the + parent to be marked "delivered", so its unseen clone is never tried + again. For this reason, Exim now forbids the simultaneous setting of + these two options. + +PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are + redirected to themselves ("homonym" addresses). Read the long ChangeLog + entry if you want to know the details. The fix, however, neglected to + consider the case when local delivery batching is involved. The test for + "previously delivered" was not happening when checking to see if an + address could be batched with a previous (undelivered) one; under + certain circumstances this could lead to multiple deliveries to the same + address. A one-line patch to add the appropriate test fixes the bug. + +PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T + in its include files, and this causes problems building Exim. + +PH/06 A number of "verify =" ACL conditions have no options (e.g. verify = + header_syntax) but Exim was just ignoring anything given after a slash. + In particular, this caused confusion with an attempt to use "verify = + reverse_host_lookup/defer_ok". An error is now given when options are + supplied for verify items that do not have them. (Maybe reverse_host_ + lookup should have a defer_ok option, but that's a different point.) + +PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as + defined by RFC 821) to 2048, because there were problems with some AUTH + commands, and RFC 1869 says the size should be increased for extended + SMTP commands that take arguments. + +PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony + Finch). + +PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an + "unknown" error; now it says that the functionality isn't in the binary. + +PH/10 Added a nasty fudge to try to recognize and flatten LDAP passwords in + an address' error message when a string expansion fails (syntax or + whatever). Otherwise not only does the password appear in the log, it may + also be put in a bounce message. + +PH/11 Installed exipick version 20050225.0 from John Jetmore. + +PH/12 If the last host in a fallback_hosts list was multihomed, only the first + of its addresses was ever tried. (Bugzilla bug #2.) + + A note about Exim versions 4.44 and 4.50 ---------------------------------------- @@ -343,6 +411,57 @@ Exim version 4.50 error if it is another Exim or anything else that does the synchronization check. A QUIT command is no longer sent after a timeout. +73. $host_lookup_deferred has been added, to make it easier to detect DEFERs + during host lookups. + +74. The defer_ok option of callout verification was not working if it was used + when verifying addresses in header lines, that is, for this case: + + verify = header_sender/callout=defer_ok + +75. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that + those file descriptors could be used for SMTP connections. If anything + wrote to stderr (the example that came up was "warn" in embedded Perl), it + could be sent to the SMTP client, causing chaos. The daemon now opens + stdin, stdout, and stderr to /dev/null when it puts itself into the + background. + +76. Arrange for output from Perl's "warn" command to be written to Exim's main + log by default. The user can override this with suitable Perl magic. + +77. The use of log_message on a "discard" ACL verb, which is supposed to add to + the log message when discard triggers, was not working for the DATA ACL or + for the non-SMTP ACL. + +78. Error message wording change in sieve.c. + +79. If smtp_accept_max_per_host was set, the number of connections could be + restricted to fewer than expected, because the daemon was trying to set up + a new connection before checking whether the processes handling previous + connections had finished. The check for completed processes is now done + earlier. On busy systems, this bug wouldn't be noticed because something + else would have woken the daemon, and it would have reaped the completed + process earlier. + +80. If a message was submitted locally by a user whose login name contained one + or more spaces (ugh!), the spool file that Exim wrote was not re-readable. + It caused a spool format error. I have fixed the spool reading code. A + related problem was that the "from" clause in the Received: line became + illegal because of the space(s). It is now covered by ${quote_local_part. + +81. Included the latest eximstats from Steve (adds average sizes to HTML Top + tables). + +82. Updated OS/Makefile-AIX as per message from Mike Meredith. + +83. Patch from Sieve maintainer to fix unterminated string problem in + "vacation" handling. + +84. Some minor changes to the Linux configuration files to help with other + OS variants using glibc. + +85. One more patch for Sieve to update vacation handling to latest spec. + ---------------------------------------------------- See the note above about the 4.44 and 4.50 releases.
