+Exim version 4.70
+-----------------
+
+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.
+
+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
+-----------------
+
+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.
