Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.70
+-----------------
+
+TK/01 Added patch by Johannes Berg that expands the main option
+ "spamd_servers" if it starts with a dollar sign.
+
+TK/02 Write list of recipients to X-Envelope-Sender header when building
+ the mbox-format spool file for content scanning (suggested by Jakob
+ Hirsch)
+
+TK/03 Added patch by Wolfgang Breyha that adds experimental DCC
+ (http://www.dcc-servers.net/) support via dccifd. Activated by
+ setting EXPERIMENTAL_DCC=yes in Local/Makefile. Check out
+ experimental_spec.txt for more documentation.
+
+TK/04 Bugzilla 673: Add f-protd malware scanner support. Patch submitted
+ by Mark Daniel Reidel <mr@df.eu>.
+
+NM/01 Bugzilla 657: Embedded PCRE removed from the exim source tree.
+ When building exim an external PCRE library is now needed -
+ PCRE is a system library on the majority of modern systems.
+ See entry on PCRE_LIBS in EDITME file.
+
+NM/02 Bugzilla 646: Removed unwanted C/R in Dovecot authenticator
+ conversation. Added nologin parameter to request.
+ Patch contributed by Kirill Miazine
+
+TF/01 Do not log submission mode rewrites if they do not change the address.
+
+TF/02 Bugzilla 662: Fix stack corruption before exec() in daemon.c.
+
+NM/03 Bugzilla 602: exicyclog now handles panic log, and creates empty
+ log files in place. Contributed by Roberto Lima
+
+NM/04 Bugzilla 667: close socket used by dovecot authenticator
+
+TF/03 Bugzilla 615: When checking the local_parts router precondition
+ after a local_part_suffix or local_part_prefix option, Exim now
+ does not use the address's named list lookup cache, since this
+ contains cached lookups for the whole local part.
+
+NM/05 Bugzilla 521: Integrated SPF Best Guess support contributed by
+ Robert Millan. Documentation is in experimental-spec.txt
+
+TF/04 Bugzilla 668: Fix parallel build (make -j).
+
+
+Exim version 4.69
+-----------------
+
+TK/01 Add preliminary DKIM support. Currently requires a forked version of
+ ALT-N's libdkim that I have put here:
+ http://duncanthrax.net/exim-experimental/
+
+ Note to Michael Haardt: I had to rename some vars in sieve.c. They
+ were called 'true' and it seems that C99 defines that as a reserved
+ keyword to be used with 'bool' variable types. That means you could
+ not include C99-style headers which use bools without triggering
+ build errors in sieve.c.
+
+NM/01 Bugzilla 592: --help option is handled incorrectly if exim is invoked
+ as mailq or other aliases. Changed the --help handling significantly
+ to do whats expected. exim_usage() emits usage/help information.
+
+SC/01 Added the -bylocaldomain option to eximstats.
+
+NM/02 Bugzilla 619: Defended against bad data coming back from gethostbyaddr
+
+NM/03 Bugzilla 613: Documentation fix for acl_not_smtp
+
+NM/04 Bugzilla 628: PCRE update to 7.4 (work done by John Hall)
+
+
+Exim version 4.68
+-----------------
+
+PH/01 Another patch from the Sieve maintainer.
+
+PH/02 When an IPv6 address is converted to a string for single-key lookup
+ in an address list (e.g. for an item such as "net24-dbm;/net/works"),
+ dots are used instead of colons so that keys in lsearch files need not
+ contain colons. This was done some time before quoting was made available
+ in lsearch files. However, iplsearch files do require colons in IPv6 keys
+ (notated using the quote facility) so as to distinguish them from IPv4
+ keys. This meant that lookups for IP addresses in host lists did not work
+ for iplsearch lookups.
+
+ This has been fixed by arranging for IPv6 addresses to be expressed with
+ colons if the lookup type is iplsearch. This is not incompatible, because
+ previously such lookups could never work.
+
+ The situation is now rather anomolous, since one *can* have colons in
+ ordinary lsearch keys. However, making the change in all cases is
+ incompatible and would probably break a number of configurations.
+
+TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
+ version.
+
+MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
+ conversion specification without a maximum field width, thereby enabling
+ a rogue spamd server to cause a buffer overflow. While nobody in their
+ right mind would setup Exim to query an untrusted spamd server, an
+ attacker that gains access to a server running spamd could potentially
+ exploit this vulnerability to run arbitrary code as the Exim user.
+
+TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
+ $primary_hostname instead of what libspf2 thinks the hosts name is.
+
+MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
+ a directory entry by the name of the lookup key. Previously, if a
+ symlink pointed to a non-existing file or a file in a directory that
+ Exim lacked permissions to read, a lookup for a key matching that
+ symlink would fail. Now it is enough that a matching directory entry
+ exists, symlink or not. (Bugzilla 503.)
+
+PH/03 The body_linecount and body_zerocount variables are now exported in the
+ local_scan API.
+
+PH/04 Added the $dnslist_matched variable.
+
+PH/05 Unset $tls_cipher and $tls_peerdn before making a connection as a client.
+ This means they are set thereafter only if the connection becomes
+ encrypted.
+
+PH/06 Added the client_condition to authenticators so that some can be skipped
+ by clients under certain conditions.
+
+PH/07 The error message for a badly-placed control=no_multiline_responses left
+ "_responses" off the end of the name.
+
+PH/08 Added -Mvc to output a copy of a message in RFC 2822 format.
+
+PH/09 Tidied the code for creating ratelimiting keys, creating them explicitly
+ (without spaces) instead of just copying the configuration text.
+
+PH/10 Added the /noupdate option to the ratelimit ACL condition.
+
+PH/11 Added $max_received_linelength.
+
+PH/12 Added +ignore_defer and +include_defer to host lists.
+
+PH/13 Installed PCRE version 7.2. This needed some changes because of the new
+ way in which PCRE > 7.0 is built.
+
+PH/14 Implemented queue_only_load_latch.
+
+PH/15 Removed an incorrect (int) cast when reading the value of SIZE in a
+ MAIL command. The effect was to mangle the value on 64-bit systems.
+
+PH/16 Another patch from the Sieve maintainer.
+
+PH/17 Added the NOTQUIT ACL, based on a patch from Ted Cooper.
+
+PH/18 If a system quota error occurred while trying to create the file for
+ a maildir delivery, the message "Mailbox is full" was not appended to the
+ bounce if the delivery eventually timed out. Change 4.67/27 below applied
+ only to a quota excession during the actual writing of the file.
+
+PH/19 It seems that peer DN values may contain newlines (and other non-printing
+ characters?) which causes problems in log lines. The DN values are now
+ passed through string_printing() before being added to log lines.
+
+PH/20 Added the "servers=" facility to MySQL and PostgreSQL lookups. (Oracle
+ and InterBase are left for another time.)
+
+PH/21 Added message_body_newlines option.
+
+PH/22 Guard against possible overflow in moan_check_errorcopy().
+
+PH/23 POSIX allows open() to be a macro; guard against that.
+
+PH/24 If the recipient of an error message contained an @ in the local part
+ (suitably quoted, of course), incorrect values were put in $domain and
+ $local_part during the evaluation of errors_copy.
+
+
Exim version 4.67
-----------------
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 some messages of this type were
+ selected by exigrep, they were listed as "not completed". Others were
+ picked up by some special patterns. I have improved the selection
+ criteria to be more general.
+
+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.
+
+PH/39 In a list of hosts for manualroute, if one item (either because of multi-
+ homing or because of multiple MX records with /mx) generated more than
+ one IP address, and the following item turned out to be the local host,
+ all the secondary addresses of the first item were incorrectly removed
+ from the list, along with the local host and any following hosts (which
+ is what is supposed to happen).
+
+PH/40 When Exim receives a message, it writes the login name, uid, and gid of
+ whoever called Exim into the -H file. In the case of the daemon it was
+ behaving confusingly. When first started, it used values for whoever
+ started the daemon, but after a SIGHUP it used the Exim user (because it
+ calls itself on a restart). I have changed the code so that it now always
+ uses the Exim user.
+
+PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
+ message are rejected with the same error (e.g. no authentication or bad
+ sender address), and a DATA command is nevertheless sent (as can happen
+ with PIPELINING or a stupid MUA), the error message that was given to the
+ RCPT commands is included in the rejection of the DATA command. This is
+ intended to be helpful for MUAs that show only the final error to their
+ users.
+
+PH/42 Another patch from the Sieve maintainer.
+
+SC/02 Eximstats - Differentiate between permanent and temporary rejects.
+ Eximstats - Fixed some broken HTML links and added missing column headers
+ (Jez Hancock).
+ Eximstats - Fixed Grand Total Summary Domains, Edomains, and Email
+ columns for Rejects, Temp Rejects, Ham, and Spam rows.
+
+SC/03 Eximstats - V1.58 Fix to get <> and blackhole to show in edomain tables.
+
+PH/43 Yet another patch from the Sieve maintainer.
+
+PH/44 I found a way to check for a TCP/IP connection going away before sending
+ the response to the final '.' that terminates a message, but only in the
+ case where the client has not sent further data following the '.'
+ (unfortunately, this is allowed). However, in many cases there won't be
+ any further data because there won't be any more messages to send. A call
+ to select() can be used: if it shows that the input is "ready", there is
+ either input waiting, or the socket has been closed. An attempt to read
+ the next input character can distinguish the two cases. Previously, Exim
+ would have sent an OK response which the client would never have see.
+ This could lead to message repetition. This fix should cure that, at
+ least in a lot of common cases.
+
+PH/45 Do not advertise STARTTLS in response to HELP unless it would be
+ advertised in response to EHLO.
