See NewStuff for details. + +PH/01 When a transport filter timed out in a pipe delivery, and the pipe + command itself ended in error, the underlying message about the transport + filter timeout was being overwritten with the pipe command error. Now the + underlying error message should be appended to the second error message. + +TK/01 Fix poll() being unavailable on Mac OSX 10.2. + +PH/02 Reduce the amount of output that "make" produces by default. Full output + can still be requested. + +PH/03 The warning log line about a condition test deferring for a "warn" verb + was being output only once per connection, rather than after each + occurrence (because it was using the same function as for successful + "warn" verbs). This seems wrong, so I have changed it. + +TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that + it should not have, which might have caused a crash in the right + circumstances, but probably never did. + +PH/04 Installed a modified version of Tony Finch's patch to make submission + mode fix the return path as well as the Sender: header line, and to + add a /name= option so that you can make the user's friendly name appear + in the header line. + +TF/03 Added the control = fakedefer ACL modifier. + +TF/04 Added the ratelimit ACL condition. See NewStuff for details. + +TK/02 Rewrote SPF support to work with libspf2 versions >1.2.0. + +TK/03 Merged latest SRS patch from Miles Wilton. + +PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts + with the definition in sysexits.h (which is #included earlier). + Fortunately, Exim does not actually use EX_OK. The code used to try to + preserve the sysexits.h value, by assumimg that macro definitions were + scanned for macro replacements. I have been disabused of this notion, + so now the code just undefines EX_OK before #including unistd.h. + +PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout + in the smtp transport. When a block could not be written in a single + write() function, the timeout was being re-applied to each part-write. + This seems wrong - if the receiver was accepting one byte at a time it + would take for ever. The timeout is now adjusted when this happens. It + doesn't have to be particularly precise. + +TK/04 Added simple SPF lookup method in EXPERIMENTAL_SPF. See NewStuff for + details. Thanks to Chris Webb for the patch! + +PH/07 Added "fullpostmaster" verify option, which does a check to + without a domain if the check to fails. + +SC/01 Eximstats: added -xls and the ability to specify output files + (patch written by Frank Heydlauf). + +SC/02 Eximstats: use FileHandles for outputing results. + +SC/03 Eximstats: allow any combination of xls, txt, and html output. + +SC/04 Eximstats: fixed display of large numbers with -nvr option + +SC/05 Eximstats: fixed merging of reports with empty tables. + +SC/06 Eximstats: added the -include_original_destination flag + +SC/07 Eximstats: removed tabs and trailing whitespace. + +TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller. + +TK/06 MBOX spool code: Add real "From " MBOX separator line + so the .eml file is really in mbox format (even though + most programs do not really care). Patch from Alex Miller. + +TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers. + The latter is generated from $received_to and is only set if the + message has one envelope recipient. SA can use these headers, + obviously out-of-the-box. Patch from Alex Miller. + +PH/08 The ${def test on a variable was returning false if the variable's + value was "0", contrary to what the specification has always said! + The result should be true unless the variable is empty. + +PH/09 The syntax error of a character other than { following "${if + def:variable_name" (after optional whitespace) was not being diagnosed. + An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an + accidental colon was present, for example, could give incorrect results. + +PH/10 Tidied the code in a number of places where the st_size field of a stat() + result is used (not including appendfile, where other changes are about + to be made). + +PH/11 Upgraded appendfile so that quotas larger than 2G are now supported. + This involved changing a lot of size variables from int to off_t. It + should work with maildirs and everything. + +TK/08 Apply fix provided by Michael Haardt to prevent deadlock in case of + spamd dying while we are connected to it. + + Exim version 4.51 ----------------- @@ -63,8 +167,9 @@ PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an PH/10 Added a nasty fudge to try to recognize and flatten LDAP passwords in an address' error message when a string expansion fails (syntax or - whatever).

(I'm totally confused about the + nomenclature these days.) + +PH/29 Installed patch from the Sieve maintainer that adds the options + sieve_useraddress and sieve_subaddress to the redirect router. + +PH/30 In these circumstances: + . Two addresses routed to the same list of hosts; + . First host does not offer TLS; + . First host accepts first address; + . First host gives temporary error to second address; + . Second host offers TLS and a TLS session is established; + . Second host accepts second address. + Exim incorrectly logged both deliveries with the TLS parameters (cipher + and peerdn, if requested) that were in fact used only for the second + address. + +PH/31 When doing a callout as part of verifying an address, Exim was not paying + attention to any local part prefix or suffix that was matched by the + router that accepted the address. It now behaves in the same way as it + does for delivery: the affixes are removed from the local part unless + rcpt_include_affixes is set on the transport. + +PH/32 Add the sender address, as F=<...>, to the log line when logging a + timeout during the DATA phase of an incoming message. + +PH/33 Sieve envelope tests were broken for match types other than :is. I have + applied a patch sanctioned by the Sieve maintainer. + +PH/34 Change 4.50/80 broke Exim in that it could no longer handle cases where + the uid or gid is negative. A case of a negative gid caused this to be + noticed. The fix allows for either to be negative. + +PH/35 ACL_WHERE_MIME is now declared unconditionally, to avoid too much code + clutter, but the tables that are indexed by ACL_WHERE_xxx values had been + overlooked. + +PH/36 The change PH/12 above was broken. Fixed it. + +PH/37 Exim used to check for duplicate addresses in the middle of routing, on + the grounds that routing the same address twice would always produce the + same answer. This might have been true once, but it is certainly no + longer true now. Routing a child address may depend on the previous + routing that produced that child. Some complicated redirection strategies + went wrong when messages had multiple recipients, and made Exim's + behaviour dependent on the order in which the addresses were given. + + I have moved the duplicate checking until after the routing is complete. + Exim scans the addresses that are assigned to local and remote + transports, and removes any duplicates. This means that more work will be + done, as duplicates will always all be routed, but duplicates are + presumably rare, so I don't expect this is of any significance. + + For deliveries to pipes, files, and autoreplies, the duplicate checking + still happens during the routing process, since they are not going to be + routed further. + +PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner. + It corrects a timeout issue with spamd. This is Ian's comment: "The + background is that sometimes spamd either never reads data from a + connection it has accepted, or it never writes response data. The exiscan + spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it + blindly assumes that writes won't block so it may never time out." + +PH/39 Allow G after quota size as well as K and M. + +PH/40 The value set for $authenticated_id in an authenticator may not contain + binary zeroes or newlines because the value is written to log lines and + to spool files. There was no check on this. Now the value is run through + the string_printing() function so that such characters are converted to + printable escape sequences. + +PH/41 $message_linecount is a new variable that contains the total number of + lines in the message. Compare $body_linecount, which is the count for the + body only. + +PH/42 Exim no longer gives details of delivery errors for specific addresses in + bounce and delay warning messages, except in certain special cases, which + are as follows: + + (a) An SMTP error message from a remote host; + (b) A message specified in a :fail: redirection; + (c) A message specified in a "fail" command in a system filter; + (d) A message specified in a FAIL return from the queryprogram router; + (e) A message specified by the cannot_route_message router option. + + In these cases only, Exim does include the error details in bounce and + warning messages. There are also a few cases where bland messages such + as "unrouteable address" or "local delivery error" are given. + +PH/43 $value is now also set for the "else" part of a ${run expansion. + +PH/44 Applied patch from the Sieve maintainer: "The vacation draft is still + being worked on, but at least Exim now implements the latest version to + play with." + +PH/45 In a pipe transport, although a timeout while waiting for the pipe + process to complete was treated as a delivery failure, a timeout while + writing the message to the pipe was logged, but erroneously treated as a + successful delivery. Such timeouts include transport filter timeouts. For + consistency with the overall process timeout, these timeouts are now + treated as errors, giving rise to delivery failures by default. However, + there is now a new Boolean option for the pipe transport called + timeout_defer, which, if set TRUE, converts the failures into defers for + both kinds of timeout. A transport filter timeout is now identified in + the log output. + +PH/46 The "scripts/Configure-config.h" script calls "make" at one point. On + systems where "make" and "gmake" are different, calling "gmake" at top + level broke things. I've arranged for the value of $(MAKE) to be passed + from the Makefile to this script so that it can call the same version of + "make". + A note about Exim versions 4.44 and 4.50 ----------------------------------------
