Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.77
+-----------------
+
+PP/01 Solaris build fix for Oracle's LDAP libraries.
+ Bugzilla 1109, patch from Stephen Usher.
+
+TF/01 HP/UX build fix: avoid arithmetic on a void pointer.
+
+TK/01 DKIM Verification: Fix relaxed canon for empty headers w/o
+ whitespace trailer
+
+TF/02 Fix a couple more cases where we did not log the error message
+ when unlink() failed. See also change 4.74-TF/03.
+
+TF/03 Make the exiwhat support code safe for signals. Previously Exim might
+ lock up or crash if it happened to be inside a call to libc when it
+ got a SIGUSR1 from exiwhat.
+
+ The SIGUSR1 handler appends the current process status to the process
+ log which is later printed by exiwhat. It used to use the general
+ purpose logging code to do this, but several functions it calls are
+ not safe for signals.
+
+ The new output code in the SIGUSR1 handler is specific to the process
+ log, and simple enough that it's easy to inspect for signal safety.
+ Removing some special cases also simplifies the general logging code.
+ Removing the spurious timestamps from the process log simplifies
+ exiwhat.
+
+TF/04 Improved ratelimit ACL condition.
+
+ The /noupdate option has been deprecated in favour of /readonly which
+ has clearer semantics. The /leaky, /strict, and /readonly update modes
+ are mutually exclusive. The update mode is no longer included in the
+ database key; it just determines when the database is updated. (This
+ means that when you upgrde Exim will forget old rate measurements.)
+
+ Exim now checks that the per_* options are used with an update mode that
+ makes sense for the current ACL. For example, when Exim is processing a
+ message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
+ per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
+ must specify per_mail/readonly. If you omit the update mode it defaults to
+ /leaky where that makes sense (as before) or /readonly where required.
+
+ The /noupdate option is now undocumented but still supported for
+ backwards compatibility. It is equivalent to /readonly except that in
+ ACLs where /readonly is required you may specify /leaky/noupdate or
+ /strict/noupdate which are treated the same as /readonly.
+
+ A useful new feature is the /count= option. This is a generalization
+ of the per_byte option, so that you can measure the throughput of other
+ aggregate values. For example, the per_byte option is now equivalent
+ to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
+
+ The per_rcpt option has been generalized using the /count= mechanism
+ (though it's more complicated than the per_byte equivalence). When it is
+ used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
+ measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
+ or in a non-SMTP ACL it adds all the recipients in one go. (The latter
+ /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
+ Note that using per_rcpt with a non-readonly update mode in more than
+ one ACL will cause the recipients to be double-counted. (The per_mail
+ and per_byte options don't have this problem.)
+
+ The handling of very low rates has changed slightly. If the computed rate
+ is less than the event's count (usually one) then this event is the first
+ after a long gap. In this case the rate is set to the same as this event's
+ count, so that the first message of a spam run is counted properly.
+
+ The major new feature is a mechanism for counting the rate of unique
+ events. The new per_addr option counts the number of different
+ recipients that someone has sent messages to in the last time period. It
+ behaves like per_rcpt if all the recipient addresses are different, but
+ duplicate recipient addresses do not increase the measured rate. Like
+ the /count= option this is a general mechanism, so the per_addr option
+ is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
+ example, measure the rate that a client uses different sender addresses
+ with the options per_mail/unique=$sender_address. There are further
+ details in the main documentation.
+
+TF/05 Removed obsolete $Cambridge$ CVS revision strings.
+
+TF/06 Removed a few PCRE remnants.
+
+
+Exim version 4.76
+-----------------
+
+PP/01 The new ldap_require_cert option would segfault if used. Fixed.
+
+PP/02 Harmonised TLS library version reporting; only show if debugging.
+ Layout now matches that introduced for other libraries in 4.74 PP/03.
+
+PP/03 New openssl_options items: no_sslv2 no_sslv3 no_ticket no_tlsv1
+
+PP/04 New "dns_use_edns0" global option.
+
+PP/05 Don't segfault on misconfiguration of ref:name exim-user as uid.
+ Bugzilla 1098.
+
+PP/06 Extra paranoia around buffer usage at the STARTTLS transition.
+ nb: Exim is not vulnerable to http://www.kb.cert.org/vuls/id/555316
+
+TK/01 Updated PolarSSL code to 0.14.2.
+ Bugzilla 1097. Patch from Andreas Metzler.
+
+PP/07 Catch divide-by-zero in ${eval:...}.
+ Fixes bugzilla 1102.
+
+PP/08 Condition negation of bool{}/bool_lax{} did not negate. Fixed.
+ Bugzilla 1104.
+
+TK/02 Bugzilla 1106: CVE-2011-1764 - DKIM log line was subject to a
+ format-string attack -- SECURITY: remote arbitrary code execution.
+
+TK/03 SECURITY - DKIM signature header parsing was double-expanded, second
+ time unintentionally subject to list matching rules, letting the header
+ cause arbitrary Exim lookups (of items which can occur in lists, *not*
+ arbitrary string expansion). This allowed for information disclosure.
+
+PP/09 Fix another SIGFPE (x86) in ${eval:...} expansion, this time related to
+ INT_MIN/-1 -- value coerced to INT_MAX.
+

+
+TF/02 Bugzilla 139: Avoid using the += operator in the modular lookup
+ makefiles for portability to HP-UX and POSIX correctness.

+ With thanks to Steve Haslam, Johannes Berg & Serge Demonchaux
+ for maintaining out-of-tree patches for some time.
+
+PP/01 Bugzilla 139: Documentation and portability issues.
+ Avoid GNU Makefile-isms, let Exim continue to build on BSD.
+ Handle per-OS dynamic-module compilation flags.
+
+PP/02 Let /dev/null have normal permissions.
+ The 4.73 fixes were a little too stringent and complained about the
+ permissions on /dev/null. Exempt it from some checks.
+ Reported by Andreas M. Kirchwitz.
+
+PP/03 Report version information for many libraries, including
+ Exim version information for dynamically loaded libraries. Created
+ version.h, now support a version extension string for distributors
+ who patch heavily. Dynamic module ABI change.
+
+PP/04 CVE-2011-0017 - check return value of setuid/setgid. This is a
+ privilege escalation vulnerability whereby the Exim run-time user
+ can cause root to append content of the attacker's choosing to
+ arbitrary files.
+
+PP/05 Bugzilla 1041: merged DCC maintainer's fixes for return code.
+ (Wolfgang Breyha)
+
+PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
+ If dropping privileges for untrusted macros, we disabled normal logging
+ on the basis that it would fail; for the Exim run-time user, this is not
+ the case, and it resulted in successful deliveries going unlogged.
+ Fixed. Reported by Andreas Metzler.
+
+
+Exim version 4.73
+-----------------
+

+
+PP/05 Bugzilla 834: provide a permit_coredump option for pipe transports.
+
+PP/06 Adjust NTLM authentication to handle SASL Initial Response.
+
+PP/07 If TLS negotiated an anonymous cipher, we could end up with SSL but
+ without a peer certificate, leading to a segfault because of an
+ assumption that peers always have certificates. Be a little more
+ paranoid. Problem reported by Martin Tscholak.
+
+PP/08 Bugzilla 926: switch ClamAV to use the new zINSTREAM API for content
+ filtering; old API available if built with WITH_OLD_CLAMAV_STREAM=yes
+ NB: ClamAV planning to remove STREAM in "middle of 2010".
+ CL also introduces -bmalware, various -d+acl logging additions and
+ more caution in buffer sizes.
+

+
+PP/10 Bugzilla 937: provide a "debug" ACL control.
+
+PP/11 Bugzilla 922: Documentation dusting, patch provided by John Horne.

+PP/14 Build without WITH_CONTENT_SCAN. Path from Andreas Metzler.
+
+PP/15 Bugzilla 816: support multiple condition rules on Routers.
+
+PP/16 Add bool_lax{} expansion operator and use that for combining multiple
+ condition rules, instead of bool{}. Make both bool{} and bool_lax{}
+ ignore trailing whitespace.

+ ExtendedDetectionInfo response format.
+ Notification from John Horne.
+
+PP/19 OpenSSL 1.0.0a compatibility const-ness change, should be backwards
+ compatible.
+
+PP/20 Added a CONTRIBUTING file. Fixed the documentation build to use http:
+ XSL and documented dependency on system catalogs, with examples of how
+ it normally works.
+
+DW/21 Added Valgrind hooks in store.c to help it capture out-of-bounds store
+ access.
+
+DW/22 Bugzilla 1044: CVE-2010-4345 - partial fix: restrict default behaviour
+ of CONFIGURE_OWNER and CONFIGURE_GROUP options to no longer allow a
+ configuration file which is writeable by the Exim user or group.
+
+DW/23 Bugzilla 1044: CVE-2010-4345 - part two: extend checks for writeability
+ of configuration files to cover files specified with the -C option if
+ they are going to be used with root privileges, not just the default
+ configuration file.
+
+DW/24 Bugzilla 1044: CVE-2010-4345 - part three: remove ALT_CONFIG_ROOT_ONLY
+ option (effectively making it always true).
+
+DW/25 Add TRUSTED_CONFIG_PREFIX_FILE option to allow alternative configuration
+ files to be used while preserving root privileges.
+
+DW/26 Set FD_CLOEXEC on SMTP sockets after forking in the daemon, to ensure
+ that rogue child processes cannot use them.
+
+PP/27 Bugzilla 1047: change the default for system_filter_user to be the Exim
+ run-time user, instead of root.
+
+PP/28 Add WHITELIST_D_MACROS option to let some macros be overridden by the
+ Exim run-time user without dropping privileges.
+
+DW/29 Remove use of va_copy() which breaks pre-C99 systems. Duplicate the
+ result string, instead of calling string_vformat() twice with the same
+ arguments.
+
+DW/30 Allow TRUSTED_CONFIG_PREFIX_FILE only for Exim or CONFIGURE_OWNER, not
+ for other users. Others should always drop root privileges if they use
+ -C on the command line, even for a whitelisted configure file.
+
+DW/31 Turn TRUSTED_CONFIG_PREFIX_FILE into TRUSTED_CONFIG_FILE. No prefixes.

+
+
+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

+
+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

+
+
+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 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.
+
+
+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
+-----------------
+
+TK/01 Disable default definition of HAVE_LINUX_SENDFILE. Clashes with
+ Linux large file support (_FILE_OFFSET_BITS=64) on older glibc
+ versions. (#438)
+
+MH/01 Don't check that the operands of numeric comparison operators are
+ 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.
+
+
Exim version 4.64
-----------------
+TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
+ leftover -K file (the existence of which was triggered by #402).
+ While we were at it, introduced process PID as part of the -K
+ filename. This should rule out race conditions when creating
+ these files.
+
+TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
+ processing considerably. Previous code took too long for large mails,
+ triggering a timeout which in turn triggers #401.
+
+TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
+ in the DK code in transports.c. sendfile() is not really portable,
+ hence the _LINUX specificness.
+
TF/01 In the add_headers option to the mail command in an Exim filter,
there was a bug that Exim would claim a syntax error in any
header after the first one which had an odd number of characters
addresses), $smtp_active_hostname is used.
PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
- tweaks were necessary in order to get it to work:
+ tweaks were necessary in order to get it to work (see also 21 below):
(a) The code assumed that strncpy() returns a negative number on buffer
overflow, which isn't the case. Replaced with Exim's string_format()
function.
but it didn't always do it. This confused somebody who was copying the
code for some other use. I have removed all the tests.
+PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
+ feature that was used to support insecure browsers during the U.S. crypto
+ embargo. It requires special client support, and Exim is probably the
+ only MTA that supported it -- and would never use it because real RSA is
+ always available. This code has been removed, because it had the bad
+ effect of slowing Exim down by computing (never used) parameters for the
+ RSA_EXPORT functionality.
+
+PH/21 On the advice of Timo Sirainen, added a check to the dovecot
+ authenticator to fail if there's a tab character in the incoming data
+ (there should never be unless someone is messing about, as it's supposed
+ to be base64-encoded). Also added, on Timo's advice, the "secured" option
+ if the connection is using TLS or if the remote IP is the same as the
+ local IP, and the "valid-client-cert option" if a client certificate has
+ been verified.
+
+PH/22 As suggested by Dennis Davis, added a server_condition option to *all*
+ authenticators. This can be used for authorization after authentication
+ succeeds. (In the case of plaintext, it servers for both authentication
+ and authorization.)
+
+PH/23 Testing for tls_required and lost_connection in a retry rule didn't work
+ if any retry times were supplied.
+
+PH/24 Exim crashed if verify=helo was activated during an incoming -bs
+ connection, where there is no client IP address to check. In this
+ situation, the verify now always succeeds.
+
+PH/25 Applied John Jetmore's -Mset patch.
+
+PH/26 Added -bem to be like -Mset, but loading a message from a file.
+
+PH/27 In a string expansion for a processed (not raw) header when multiple
+ headers of the same name were present, leading whitespace was being
+ removed from all of them, but trailing whitespace was being removed only
+ from the last one. Now trailing whitespace is removed from each header
+ before concatenation. Completely empty headers in a concatenation (as
+ before) are ignored.
+
+PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John
+ Jetmore). It would have mis-read ACL variables from pre-4.61 spool files.
+
+PH/29 [Removed. This was a change that I later backed out, and forgot to
+ correct the ChangeLog entry (that I had efficiently created) before
+ committing the later change.]
+
+PH/30 Exim was sometimes attempting to deliver messages that had suffered
+ address errors (4xx response to RCPT) over the same connection as other
+ messages routed to the same hosts. Such deliveries are always "forced",
+ so retry times are not inspected. This resulted in far too many retries
+ for the affected addresses. The effect occurred only when there were more
+ hosts than the hosts_max_try setting in the smtp transport when it had
+ the 4xx errors. Those hosts that it had tried were not added to the list
+ of hosts for which the message was waiting, so if all were tried, there
+ was no problem. Two fixes have been applied:
+
+ (i) If there are any address or message errors in an SMTP delivery, none
+ of the hosts (tried or untried) are now added to the list of hosts
+ for which the message is waiting, so the message should not be a
+ candidate for sending over the same connection that was used for a
+ successful delivery of some other message. This seems entirely
+ reasonable: after all the message is NOT "waiting for some host".
+ This is so "obvious" that I'm not sure why it wasn't done
+ previously. Hope I haven't missed anything, but it can't do any
+ harm, as the worst effect is to miss an optimization.
+
+ (ii) If, despite (i), such a delivery is accidentally attempted, the
+ routing retry time is respected, so at least it doesn't keep
+ hammering the server.
+
+PH/31 Installed Andrew Findlay's patch to close the writing end of the socket
+ in ${readsocket because some servers need this prod.
+
+PH/32 Added some extra debug output when updating a wait-xxx database.
+
+PH/33 The hint "could be header name not terminated by colon", which has been
+ given for certain expansion errors for a long time, was not being given
+ for the ${if def:h_colon_omitted{... case.
+
+PH/34 The spec says: "With one important exception, whenever a domain list is
+ being scanned, $domain contains the subject domain." There was at least
+ one case where this was not true.
+
+PH/35 The error "getsockname() failed: connection reset by peer" was being
+ written to the panic log as well as the main log, but it isn't really
+ panic-worthy as it just means the connection died rather early on. I have
+ removed the panic log writing for the ECONNRESET error when getsockname()
+ fails.
+
+PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
+ runs only) independently of the message's sender address. This meant
+ that, if the 4xx error was in fact related to the sender, a different
+ message to the same recipient with a different sender could confuse
+ things. In particualar, this can happen when sending to a greylisting
+ server, but other circumstances could also provoke similar problems.
+ I have changed the default so that the retry time for these errors is now
+ based a combination of the sender and recipient addresses. This change
+ can be overridden by setting address_retry_include_sender=false in the
+ smtp transport.
+
+PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the
+ remote server are returned as part of bounce messages. This was not
+ happening for LMTP over a pipe (the lmtp transport), but now it is the
+ same for both kinds of LMTP.
+
+PH/38 Despite being documented as not happening, Exim was rewriting addresses
+ in header lines that were in fact CNAMEs. This is no longer the case.
+
+PH/39 If -R or -S was given with -q<time>, the effect of -R or -S was ignored,
+ and queue runs started by the daemon processed all messages. This has
+ been fixed so that -R and -S can now usefully be given with -q<time>.
+
+PH/40 Import PCRE release 6.7 (fixes some bugs).
+
+PH/41 Add bitwise logical operations to eval (courtesy Brad Jorsch).
+
+PH/42 Give an error if -q is specified more than once.
+
+PH/43 Renamed the variables $interface_address and $interface_port as
+ $received_ip_address and $received_port, to make it clear that these
+ values apply to message reception, and not to the outgoing interface when
+ a message is delivered. (The old names remain recognized, of course.)
+
+PH/44 There was no timeout on the connect() call when using a Unix domain
+ socket in the ${readsocket expansion. There now is.
+
+PH/45 Applied a modified version of Brad Jorsch's patch to allow "message" to
+ be meaningful with "accept".
+
+SC/01 Eximstats V1.43
+ Bug fix for V1.42 with -h0 specified. Spotted by Chris Lear.
+
+SC/02 Eximstats V1.44
+ Use a glob alias rather than an array ref in the generated

+
+SC/03 Eximstats V1.45 (Marco Gaiarin / Steve Campbell)
+ Collect SpamAssassin and rejection statistics.
+ Don't display local sender or destination tables unless
+ there is data to show.
+ Added average volumes into the top table text output.
+
+SC/04 Eximstats V1.46
+ Collect data on the number of addresses (recipients)
+ as well as the number of messages.
+
+SC/05 Eximstats V1.47
+ Added 'Message too big' to the list of mail rejection
+ reasons (thanks to Marco Gaiarin).
+
+SC/06 Eximstats V1.48
+ Mainlog lines which have GMT offsets and are too short to
+ have a flag are now skipped.
+
+SC/07 Eximstats V1.49 (Alain Williams)
+ Added the -emptyok flag.
+
+SC/08 Eximstats V1.50
+ Fixes for obtaining the IP address from reject messages.
+
+JJ/03 exipick.20061117.2, made header handling as similar to exim as possible

+
+JJ/07 exipick.20061117.2, added $received_ip_address and $received_port

+
+PH/46 Applied Jori Hamalainen's patch to add features to exiqsumm.
+
+PH/47 Put in an explicit test for a DNS lookup of an address record where the
+ "domain" is actually an IP address, and force a failure. This locks out
+ those revolvers/nameservers that support "A-for-A" lookups, in
+ contravention of the specifications.
+
+PH/48 When a host name was looked up from an IP address, and the subsequent
+ forward lookup of the name timed out, the host name was left in
+ $sender_host_name, contrary to the specification.
+
+PH/49 Although default lookup types such as lsearch* or cdb*@ have always been
+ restricted to single-key lookups, Exim was not diagnosing an error if
+ * or *@ was used with a query-style lookup.
+
+PH/50 Increased the value of DH_BITS in tls-gnu.c from 768 to 1024.
+
+MH/01 local_scan ABI version incremented to 1.1. It should have been updated
+ long ago, but noone interested enough thought of it. Let's just say that
+ the "1.1" means that there are some new functions that weren't there at
+ some point in the past.
+
+PH/51 Error processing for expansion failure of helo_data from an smtp

+
+PH/52 Applied John Jetmore's patch to allow tls-on-connect and STARTTLS to be
