* 2006/01/09 - v4.2.1 (sa-exim.tar.gz or local_scan only)
     Security update (reported by Chris Morris)
       * Modified Greylisting.pm not to generate tuplets with spaces,
         although the cleaning cron job is now safe with regard to whitespace
       * Included Mark Lawrence's perl script to better clean old tuplets
       * The default config now ships with the greylistclean cronjob running
         as nobody (which spamd should be running as, too)
   * 2005/01/17 - v4.2 (sa-exim.tar.gz or local_scan only)
     Do not use, greylistclean is insecure, use 4.2.1 instead
       * Fixed code so that it compiles inside the exim tree too (thanks
         Jason)
       * Support SA 3.0 new score reporting format (score= instead of hits=)
       * Proper SA 3.0 plugin support
       * Documentation updates
       * greylisting files now also save the last SA score, just in case
       * Saved files are now group read/write too, if you need to shut off
         group access, do it at the directory level
       * Only rewrite Content-Type/Content-Transfer-Encoding if SARewriteBody
         is on now (this used to be useful with old SA versions and
         defang_mime but those options are gone). Suggested by Adam Tilghman.
       * Finally made all score threshold variables exim conditions that are
         evaluated at runtime
       * SAteergrubecond is deprecated as a result
   * 2004/08/16 - v4.1 (sa-exim.tar.gz or local_scan only) Please see the
     mailing list, or use the CVS version if you are compiling sa-exim inside
     your exim tree (there is a small mistake in the source which will
     prevent proper building) / You also need CVS if you are using SA 3.0
       * Deal with being called with the number of recipients is 0 (reported
         by John Horne)
       * Made hopefully fully 64 bit clean (well, it was written that way,
         except for that pesky printf in C, which got in the way). Kudos go
         to Adam D. Barratt for finding and explaining the bug
       * Switched to using strchr instead of index to remove compilation
         warnings on some systems (reported by John Horne/Jeff Carter)
       * Added SAspamcHost/SAspamcPort at the request of several people
       * Fixed mbox From file to be standards complaint (reported by Cliff
         Hones)
       * Added SAFEMESGIDCHARS option for safer message-id based filenames
       * New version of the SA patch, with safe file creation (clean env from
         and rcpt to before using as directory names)
       * IMPORTANT: if you are using greylisting, and applied the previous
         greylisting patch, it didn't create shell safe filenames, it is
         therefore highly recommended that you apply the new version
       * Added a quick patch to sa-exim to deal with headers that are longer
         than 8K (and drop the remaining lines)
   * 2004/03/16 - v4.0 (sa-exim.tar.gz or local_scan only)
       * Added SAspamcpath (from Richard Lithvall)
       * Makefile fixes for version.h and dependencies
       * Added exim acl_m trick from Chirik in README
       * New code to read and pass on any X-Spam- header from SpamAssassin
       * Message-Id is now logged in SA log entries to allow you track down a
         message in other logfiles, like SA's log
       * Add X-SA-Exim-Connect-IP header for greylisting
       * Allow for tempreject on messages not flagged as spam by SA (for
         greylisting)
       * Added greylisting support (see README.greylisting)
       * Added the following options to sa-exim.conf:
            * SAspamcSockPath
            * SAgreylistiswhitestr
            * SAgreylistraisetempreject
       * Lots of documentation fixes and updates
       * Basic debian tree shipped by default (but real deb package from
         Sander Smeenk)
   * 2003/08/18 - v3.1 (sa-exim tar.gz or local_scan only)
       * Fixed SA: Action: teergrubed sender until full configured duration
         output
       * spamassassin.conf was renamed sa-exim.conf (bad initial name choice)
       * Changed teergrubing so that it works with exim 4.20 and above
       * Added the much requested SARewriteBody option for SA 2.50's
         report_safe (courtesy of Richard Lithvall)
       * Added SAaddSAEheaderBeforeSA to deal with SARewriteBody and privacy
       * Added SAPrependArchiveWithFrom option (Richard Lithvall)
       * As announced in the previous version, SAStallSender was removed. Use
         Teergrubing instead
       * Message-Id is read directly from Exim now that the API allows for
         that (we used to parse the Message-Id header ourselves) -> except
         that we don't use this for logging or saving messages: as soon as we
         can read the real Message-Id from the headers, we use that
         Message-Id for logging (this is to facilitate tracking of messages
         from the logs and correlating with something like SA timelog files)
       * Logging improved some more: Message-Id is added to log entries, as
         well as the full mailinfo whether the message is spam or not
   * 2003/04/30 - v3.0 (sa-exim tar.gz or local_scan only)
       * Makefile can generate a short sa-exim.conf (for Brian Kendig)
       * Added a contrib directory with 3rd party scripts
       * Since we already had X-SA-Exim-Rcpt-To: to show the envelope to
         (disabled by default), I added X-SA-Exim-Mail-From: to show the
         envelope from (always enabled, but you can delete it in
         system_filter if you wish). If you can't easily see or parse the
         envelope sender in your mails, this should definitely help
       * Much improved directory creation and error handling for the reject
         save directories
       * Added SIGCHLD patch from David Woodhouse
       * Added version header that looks like this: X-SA-Exim-Version:
         2.2.x-cvs (built Tue Apr 22 10:28:25 PDT 2003)
       * Rewrote pretty much every log message to be more consistent and
         grepable (the previous ones were quite bad). Suggested by multiple
         people including Brian Kendig
       * Made the SMTP error messages finally configurable (suggested by
         several people). This is now possible since exim lets me output a
         different message in the log than in the SMTP session. Consequently,
         new default messages do not show the spam score, this only goes to
         the exim now.
       * Made SAmaxrcptlistlength and option to control how long of a
         X-SA-Exim-Rcpt-To header you can output if you want to output it at
         all
       * Do not output "savemail condition expanded to false" if not in debug
         mode (as reported by Brian Kendig)
       * Now ships with a sample local_scan.h if we can't find the exim
         source
       * Change of logic to delete SA headers that were in the original mail
         but weren't outputted by the SA run (like X-Spam-Flag, as reported
         by Chad Leigh)
       * Modified local_scan dlopen patch to deal with updates to the exim
         local_scan API
       * The default location for spamasassin.conf was changed to /etc/exim4
         (debian default)
       * Updated README and INSTALL
       * Updated localscan_dlopen.patch to deal with minor/major version
         numbers
       * Added X-SA-Exim-Version
   * 2002/10/28 - v2.2 (sa-exim tar.gz or local_scan only)
       * Fixed a bug that affected all mails bigger than what spamc would
         accept. Doh! (it not clear why, but spamc would hang and stop
         reading after it had been fed more than it was willing to accept)
       * Added more debugging code to help track the above problem
       * Depending on SATruncBodyCond will now either not pass a message
         that's too big to spamc, or will optionally truncate it first
       * Now strips any X-SA-Exim-* headers already present in the message
         before scanning it
       * Added new X-SA-Exim-Rcpt-To: header (see privacy section in README)
         after a suggestion from Brian Kendig
       * Teergrube is now spelled correctly (note that the option names in
         sa-exim.conf changed as a result)
       * Teergrubing has been re-implemented to detect that the other side
         went away so that exim doesn't stay around for nothing.
       * Added SAteergrubecond so that you don't teergrube your neighbours
       * Small cleanups
   * 2002/10/13 - v2.1 (buggy) (sa-exim tar.gz or local_scan only)
       * Default mail config is now in /etc/exim instead of /etc/mail
       * Fixed SAstallsender so that exim doesn't leave spool files behind
       * Fixed comparison for spam values as suggested by Patrice Fournier
       * Returned a header saying whether SA-Exim was able to scan the mail
         or not (based on a suggestion from Patrice Fournier)
       * Added support for teergrubing as suggested by Robert Strickler (see
         http://www.iks-jena.de/mitarb/lutz/usenet/teergrube.en.html)
       * We now make sure that we feed spamc a little more data than it's
         willing to accept. That way, we don't feed a truncated message
       * sa-exim.conf now appends /new on save directories so that they are
         valid maildir spool and you can run mutt -f dirname to read
       * Small cleanups
   * 2002/07/07 - v2.0.1 (sa-exim tar.gz or local_scan only)
       * Removed unneeded ## concatenation in macro
       * Fixed lseek call, as reported by Peter N Lewis
       * Improved Makefile for documentation
       * Suggestion from dman to allow for config options overrides in
         Makefile
       * Fixed all the compiler warnings that were fixable
       * Handle more kinds of Message-Id as suggested by Patrice Fournier
   * 2002/06/14 - v2.0 (sa-exim tar.gz or local_scan only)
       * Allow for stalling SMTP sessions from spammers (caution)
       * Support X-Spam-Status from SA pre 2.30
       * Build patches from Norm
       * Documented that spamd shouldn't be run with -c
       * dman's patch to allow for this to be a shared library
       * dman's indirect request for saved files to be 660
   * 2002/06/01 - v2.0b1
     This is how 1.0 would have been if I had done it right :-)
       * We now attempt to create directories we write to (suggestion from
         Patrice Fournier)
       * Log envelope sender, recipients and connecting host on rejected
         messages (suggestion from Patrice Fournier)
       * We can now save non rejected messages whether they were flagged as
         spam or not (based on request from Patrice)
       * Each save rule now has its own condition that lets you decide which
         messages you want to save or not
       * Fixed parsing of Message-Id. May not parse all of them but won't do
         anything stupid with bad input
       * Fixed a buglet where we removed old headers before knowing whether
         they were going to be replaced.
       * Added much needed internal alarm so that we don't run too long
       * I added lots of options, but weren't able to test all of them and
         their combinations, please reports problems you may notice and
         documentation issues (in config file)
       * Thanks also go to dman for his plentiful feedback
   * 2002/05/21 - v1.3
       * We now close the files we create on disk. Duh!
   * 2002/05/17 - v1.2.2
       * SA options are now kept in memory. Small cleanups
   * 2002/05/13 - v1.2.1
       * v1.2 (unreleased) didn't work right: it tagged messages properly,
         but failed to see what was marked as spam and couldn't reject
         messages. Fixed.
       * Stripped newlines in header lines (better for logging)
       * fixed header_add bug if headers contained '%'
   * 2002/05/12 - v1.2 (unreleased)
       * According to Craig R Hughes, any X-Spam header can be multiline.
         Let's parse them accordingly
   * 2002/05/08 - v1.1.1
       * Added fake envelope from to mails that we save on disk so that they
         can be opened with MUAs (idea from dman)
   * 2002/05/07 - v1.1
       * Cleaned up and fixed multiline header parsing
       * Added parsing of Subject back from Spamc (suggestion from dman)
       * We now log how long spamc took, and all messages processed by spamc
         get logged in mainlog so that we know the outcome
       * Added custom header compare function to handle mixed case headers
   * 2002/05/06 - v1.0.1
       * Fixed problems with reading Content-Type back from spamc (we used to
         read whole body too, ooops...)
       * Handle multi-line Content-Type headers.
       * All log entries now start with "SA: "
       * If SA gets run twice, we drop the previous X-Spam headers
       * Support for X-Spam-Prev-Content-Transfer-Encoding
   * 2002/05/05 - v1.0
       * *Many* changes. This is now a real program with hopefully most of
         the configuration options people could need
       * Fully configurable through external config file
       * Condition to run or not run SA against a message
       * 3 Levels of spam handling
       * Option to save messages that are rejected or cause errors
       * Very complete error checking
   * 2002/04/17 - v0.9.1
       * Added a few checks for possible failures
   * 2002/04/16 - v0.9
       * Pre-release
