Make + tls_dhparam take prime identifiers. Also unbreak combination of + OpenSSL+DH_params+TLSSNI. + +PP/39 Disable SSLv2 by default in OpenSSL support. + + +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. + +TF/07 Automatically extract Exim's version number from tags in the git + repository when doing development or release builds. + +PP/02 Raise smtp_cmd_buffer_size to 16kB. + Bugzilla 879.

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.

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.

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: 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.
