+PH/28 Exim tries to create and chdir to its spool directory when it starts;
+ it should be ignoring failures (because with -C, for example, it has lost
+ privilege). It wasn't ignoring creation failures other than "already
+ exists".
+
+PH/29 Added "crypteq" to the list of supported features that Exim outputs when
+ -bV or -d is used.
+
+PH/30 Fixed (presumably very longstanding) bug in exim_dbmbuild: if it failed
+ because an input line was too long, either on its own, or by virtue of
+ too many continuations, the temporary file was not being removed, and the
+ return code was incorrect.
+
+PH/31 Missing "BOOL" in function definition in filtertest.c.
+
+PH/32 Applied Sieve patches from the maintainer.
+
+TK/05 Domainkeys: Accomodate for a minor API change in libdomainkeys 0.67.
+
+PH/33 Added "verify = not_blind".
+
+PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
+ Local/Makefile (with some defaults set). These are used in built scripts
+ such as exicyclog, but they have never been used in the exim_install
+ script (though there are many overriding facilities there). I have
+ arranged that the exim_install script now takes note of these two
+ settings.
+
+PH/35 Installed configuration files for Dragonfly.
+
+PH/36 When a locally submitted message by a trusted user did not contain a
+ From: header, and the sender address was obtained from -f or from an SMTP
+ MAIL command, and the trusted user did not use -F to supply a sender
+ name, $originator_name was incorrectly used when constructing a From:
+ header. Furthermore, $originator_name was used for submission mode
+ messages from external hosts without From: headers in a similar way,
+ which is clearly wrong.
+
+PH/37 Added control=suppress_local_fixups.
+
+PH/38 When log_selector = +received_sender was set, and the addition of the
+ sender made the log line's construction buffer exactly full, or one byte
+ less than full, an overflow happened when the terminating "\n" was
+ subsequently added.
+
+PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry
+ when the result of a list match is failure because a DNS lookup failed.
+
+PH/40 RM_COMMAND is now used in the building process.
+
+PH/41 Added a "distclean" target to the top-level Makefile; it deletes all
+ the "build-* directories that it finds.
+
+PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP
+ address in a domain literal was a prefix of an interface address.
+
+PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains
+ when verifying a sender address, unless rewrite_headers is false.
+
+PH/44 Wrote a long comment about why errors_to addresses are verified as
+ recipients, not senders.
+
+TF/01 Add missing LIBS=-lm to OS/Makefile-OpenBSD which was overlooked when
+ the ratelimit ACL was added.
+
+PH/45 Added $smtp_command for the full command (cf $smtp_command_argument).
+
+PH/46 Added extra information about PostgreSQL errors to the error string.
+
+PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
+ avoiding the need to install special zones in a real server. This is
+ backwards compatible; if it can't find the fake resolver, it drops back.
+ Thus, both old and new test suites can be run.
+
+TF/02 Added util/ratelimit.pl
+
+TF/03 Minor fix to the ratelimit code to improve its behaviour in case the
+ clock is set back in time.
+
+TF/04 Fix the ratelimit support in exim_fixdb. Patch provided by Brian
+ Candler <B.Candler@pobox.com>.
+
+TF/05 The fix for PH/43 was not completely correct; widen_domains is always
+ OK for addresses that are the result of redirections.
+
+PH/48 A number of further additions for the benefit of the new test suite,
+ including a fake gethostbyname() that interfaces to the fake DNS resolver
+ (see PH/47 above).
+
+TF/06 The fix for widen_domains has also been applied to qualify_single and
+ search_parents which are the other dnslookup options that can cause
+ header rewrites.
+
+PH/49 Michael Haardt's randomized retrying, but as a separate retry parameter
+ type ("H").
+
+PH/50 Make never_users, trusted_users, admin_groups, trusted_groups expandable.
+
+TF/07 Exim produced the error message "an SRV record indicated no SMTP
+ service" if it encountered an MX record with an empty target hostname.
+ The message is now "an MX or SRV record indicated no SMTP service".
+
+TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
+ if the DNS of the sending site is misconfigured. This is quite a
+ common situation. This change restores the behaviour of treating a
+ helo verification defer as a failure.
+
