+ Fixed. Reported by Andreas Metzler.
+
+
Exim version 4.73
+-----------------
PP/01 Date: & Message-Id: revert to normally being appended to a message,
only prepend for the Resent-* case. Fixes regression introduced in

+
+PP/05 Bugzilla 834: provide a permit_coredump option for pipe transports.
+
+PP/06 Adjust NTLM authentication to handle SASL Initial Response.
+
+PP/07 If TLS negotiated an anonymous cipher, we could end up with SSL but
+ without a peer certificate, leading to a segfault because of an
+ assumption that peers always have certificates. Be a little more
+ paranoid. Problem reported by Martin Tscholak.
+
+PP/08 Bugzilla 926: switch ClamAV to use the new zINSTREAM API for content
+ filtering; old API available if built with WITH_OLD_CLAMAV_STREAM=yes
+ NB: ClamAV planning to remove STREAM in "middle of 2010".
+ CL also introduces -bmalware, various -d+acl logging additions and

+ condition rules, instead of bool{}. Make both bool{} and bool_lax{}
+ ignore trailing whitespace.
+
+JJ/02 prevent non-panic DKIM error from being sent to paniclog
+
+JJ/03 added tcp_wrappers_daemon_name to allow host entries other than
+ "exim" to be used
+
+PP/17 Fix malware regression for cmdline scanner introduced in PP/08.
+ Notification from Dr Andrew Aitchison.
+
+PP/18 Change ClamAV response parsing to be more robust and to handle ClamAV's
+ ExtendedDetectionInfo response format.
+ Notification from John Horne.
+
+PP/19 OpenSSL 1.0.0a compatibility const-ness change, should be backwards
+ compatible.
+
+PP/20 Added a CONTRIBUTING file. Fixed the documentation build to use http:
+ XSL and documented dependency on system catalogs, with examples of how
+ it normally works.
+
+DW/21 Added Valgrind hooks in store.c to help it capture out-of-bounds store
+ access.
+
+DW/22 Bugzilla 1044: CVE-2010-4345 - partial fix: restrict default behaviour
+ of CONFIGURE_OWNER and CONFIGURE_GROUP options to no longer allow a
+ configuration file which is writeable by the Exim user or group.
+
+DW/23 Bugzilla 1044: CVE-2010-4345 - part two: extend checks for writeability
+ of configuration files to cover files specified with the -C option if
+ they are going to be used with root privileges, not just the default
+ configuration file.
+
+DW/24 Bugzilla 1044: CVE-2010-4345 - part three: remove ALT_CONFIG_ROOT_ONLY
+ option (effectively making it always true).
+
+DW/25 Add TRUSTED_CONFIG_PREFIX_FILE option to allow alternative configuration
+ files to be used while preserving root privileges.
+
+DW/26 Set FD_CLOEXEC on SMTP sockets after forking in the daemon, to ensure
+ that rogue child processes cannot use them.
+
+PP/27 Bugzilla 1047: change the default for system_filter_user to be the Exim
+ run-time user, instead of root.
+
+PP/28 Add WHITELIST_D_MACROS option to let some macros be overridden by the
+ Exim run-time user without dropping privileges.
+
+DW/29 Remove use of va_copy() which breaks pre-C99 systems. Duplicate the
+ result string, instead of calling string_vformat() twice with the same
+ arguments.
+
+DW/30 Allow TRUSTED_CONFIG_PREFIX_FILE only for Exim or CONFIGURE_OWNER, not
+ for other users. Others should always drop root privileges if they use
+ -C on the command line, even for a whitelisted configure file.
+
+DW/31 Turn TRUSTED_CONFIG_PREFIX_FILE into TRUSTED_CONFIG_FILE. No prefixes.
+
+NM/01 Fixed bug #1002 - Message loss when using multiple deliveries
+
