Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.67
+-----------------
+
+MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
+ is unset (happens when testing with -bh and -oMi isn't used). Thanks to
+ Jan Srzednicki.
+
+PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
+ issue a MAIL command.
+
+PH/02 In an ACL statement such as
+
+ deny dnslists = X!=127.0.0.2 : X=127.0.0.2
+
+ if a client was not listed at all, or was listed with a value other than
+ 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
+ the condition was not true (as it should be), so access was not denied.
+ The bug was that the ! inversion was incorrectly passed on to the second
+ item. This has been fixed.
+
+PH/03 Added additional dnslists conditions == and =& which are different from
+ = and & when the dns lookup returns more than one IP address.
+
+PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
+ cipher suites used by GnuTLS. These options are ignored by OpenSSL.
+
+PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
+ FSYNC, which compiles an option called disable_fsync that allows for
+ bypassing fsync(). The documentation is heavily laced with warnings.
+
+SC/01 Updated eximstats to collate all SpamAssassin rejects into one bucket.
+
+PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
+ with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
+ to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
+ including adding "make clean"; (3) Added -fPIC when compiling the test
+ dynamically loaded module, to get rid of a warning.
+
+MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
+ message fails, move_frozen_messages = true and ignore_bounce_errors_after
+ = 0s. The bug is otherwise harmless.
+
+PH/07 There was a bug in the dovecot authenticator such that the value of
+ $auth1 could be overwritten, and so not correctly preserved, after a
+ successful authentication. This usually meant that the value preserved by
+ the server_setid option was incorrect.
+
+PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.
+
+PH/09 Installed PCRE release 7.0.
+
+PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
+ run for batched SMTP input. It is now run at the start of every message
+ in the batch. While fixing this I discovered that the process information
+ (output by running exiwhat) was not always getting set for -bs and -bS
+ input. This is fixed, and it now also says "batched" for BSMTP.
+
+PH/11 Added control=no_pipelining.
+
+PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
+ patch, slightly modified), and move the expansion of helo_data till after
+ the connection is made in the smtp transport (so it can use these
+ values).
+
+PH/13 Added ${rfc2047d: to decoded RFC 2047 strings.
+
+PH/14 Added log_selector = +pid.
+
+PH/15 Flush SMTP output before delaying, unless control=no_delay_flush is set.
+
+PH/16 Add ${if forany and ${if forall.
+
+PH/17 Added dsn_from option to vary the From: line in DSNs.
+
+PH/18 Flush SMTP output before performing a callout, unless control =
+ no_callout_flush is set.
+
+PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
+ was true (the default) a successful delivery failed to delete the retry
+ item, thus causing premature timeout of the address. The bug is now
+ fixed.
+
+PH/20 Added hosts_avoid_pipelining to the smtp transport.
+
+PH/21 Long custom messages for fakedefer and fakereject are now split up
+ into multiline reponses in the same way that messages for "deny" and
+ other ACL rejections are.
+
+PH/22 Applied Jori Hamalainen's speed-up changes and typo fixes to exigrep,
+ with slight modification.
+
+PH/23 Applied sieve patches from the maintainer "tracking the latest notify
+ draft, changing the syntax and factoring some duplicate code".
+
+PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
+ for deliveries of the second and subsequent messages over the same SMTP
+ connection.
+
+PH/25 Applied Magnus Holmgren's patch for ${addresses, ${map, ${filter, and
+ ${reduce, with only minor "tidies".
+
+SC/02 Applied Daniel Tiefnig's patch to improve the '($parent) =' pattern match.
+
+PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
+ expansion side effects.
+
+PH/27 When a message times out after an over-quota error from an Exim-imposed
+ quota, the bounce message says "mailbox is full". This message was not
+ being given when it was a system quota that was exceeded. It now should
+ be the same.
+
+MH/03 Made $recipients available in local_scan(). local_scan() already has
+ better access to the recipient list through recipients_list[], but
+ $recipients can be useful in postmaster-provided expansion strings.
+
+PH/28 The $smtp_command and $smtp_command_argument variables were not correct
+ in the case of a MAIL command with additional options following the
+ address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
+ were accidentally chopped off.
+
+PH/29 SMTP synchronization checks are implemented when a command is read -
+ there is a check that no more input is waiting when there shouldn't be
+ any. However, for some commands, a delay in an ACL can mean that it is
+ some time before the response is written. In this time, more input might
+ arrive, invalidly. So now there are extra checks after an ACL has run for
+ HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
+ pipelining has not been advertised.
+
+PH/30 MH's patch to allow iscntrl() characters to be list separators.
+
+PH/31 Unlike :fail:, a custom message specified with :defer: was not being
+ returned in the SMTP response when smtp_return_error_details was false.
+ This has been fixed.
+
+PH/32 Change the Dovecot authenticator to use read() and write() on the socket
+ instead of the C I/O that was originally supplied, because problems were
+ reported on Solaris.
+
+PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
+ Exim which did not show up earlier: it was assuming that a call to
+ SSL_CTX_set_info_callback() might give an error value. In fact, there is
+ no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
+ was a macro that became an assignment, so it seemed to work. This has
+ changed to a proper function call with a void return, hence the compile
+ error. Exim's code has been fixed.
+
+PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
+ cpus.
+
+PH/35 Applied a patch from the Sieve maintainer which fixes a bug in "notify".
+
+PH/36 Applied John Jetmore's patch to add -v functionality to exigrep.
+
+PH/37 If a message is not accepted after it has had an id assigned (e.g.
+ because it turns out to be too big or there is a timeout) there is no
+ "Completed" line in the log. When such a message was selected by exigrep,
+ it was listed as "not completed". Such messages can be identified by the
+ lack of a "<=" line in the log, and they are now listed as "not
+ accepted".
+
+PH/38 The host_find_failed option in the manualroute router can now be set
+ to "ignore", to completely ignore a host whose IP address cannot be
+ found. If all hosts are ignored, the behaviour is controlled by the new
+ host_all_ignored option.
+
+
+Exim version 4.66
+-----------------
+
+PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
+ fixed by 4.65/MH/01 (is this a record?) are fixed:
+
+ (i) An empty string was always treated as zero by the numeric comparison
+ operators. This behaviour has been restored.
+
+ (ii) It is documented that the numeric comparison operators always treat
+ their arguments as decimal numbers. This was broken in that numbers
+ starting with 0 were being interpreted as octal.
+
+ While fixing these problems I realized that there was another issue that
+ hadn't been noticed. Values of message_size_limit (both the global option
+ and the transport option) were treated as octal if they started with 0.
+ The documentation was vague. These values are now always treated as
+ decimal, and I will make that clear in the documentation.
+
+
Exim version 4.65
-----------------
integers when their expansion is in "skipping" mode (fixes bug
introduced by 4.64-PH/07).
+PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
+ child addresses, Exim now panics and dies. Previously, because the count
+ is held in a short int, deliveries were likely to be lost. As such a
+ large number of recipients for a single message is ridiculous
+ (performance will be very, very poor), I have chosen to impose a limit
+ rather than extend the field.
+
