Change log file for Exim from version 4.21
-------------------------------------------
+Exim version 4.52
+-----------------
+
+TF/01 Added support for Client SMTP Authorization. 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.
+
+
Exim version 4.51
-----------------
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). Otherwise not only does the password appear in the log, it may
- also be put in a bounce message.
+ whatever). Otherwise the password may appear in the log. Following change
+ PH/42 below, there is no longer a chance of it appearing in a bounce
+ message.
PH/11 Installed exipick version 20050225.0 from John Jetmore.
to the debugging output, even when log_selector=+arguments is not
specified.
+PH/26 Change scripts/os-type so that when "uname -s" returns just "GNU", the
+ answer is "GNU", and only if the return is "GNU/something" is the answer
+ "Linux".
+
+PH/27 $acl_verify_message is now set immediately after the failure of a
+ verification in an ACL, and so is available in subsequent modifiers. In
+ particular, the message can be preserved by coding like this:
+
+ warn !verify = sender
+ set acl_m0 = $acl_verify_message
+
+ Previously, $acl_verify_message was set only while expanding "message"
+ and "log_message" when a very denied access.
+
+PH/28 Modified OS/os.c-Linux with
+
+ -#ifndef OS_LOAD_AVERAGE
+ +#if !defined(OS_LOAD_AVERAGE) && defined(__linux__)
+
+ to make Exim compile on kfreebsd-gnu. (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".
