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.
+
+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 <chris@arachsys.com> for the patch!
+
+PH/07 Added "fullpostmaster" verify option, which does a check to <postmaster>
+ without a domain if the check to <postmaster@domain> 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.
+
+
Exim version 4.51
-----------------
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".
