ANNOUNCE: Stable version 4.30 released

[Julian Field]

Hi folks,

I have just released a new MailScanner stable release 4.30.
Main highlights in this month's release are more improvements to the
handling of zip files, decoding attachments and support for the AVG virus
scanner.

I have also improved the SRPM files in the Linux releases so that it will
install much more easily on new RedHat and SuSE distributions.

Download as usual from www.mailscanner.info.

The Change Log for this release is:

* New Features and Improvements *
- Zip files can now be located either by filename or by file contents, so
   you can effectively control whether your users can avoid zip file checking
   by renaming ".zip" to "_zip" for example. Note this does not affect virus
   checking, the contents of zip files will still be scanned for viruses.
   Note that this works with self-extracting zip files as well. The
   configuration option is called "Find Archives By Content" and is on by
   default.
- Tightened up MIME decoder to catch more of the tests at www.testvirus.org.
- Added support for Grisoft AVG virus scanner. Thanks to Rick Cooper for his
   hard work on this.
- BitDefender wrapper and autoupdate scripts now support both old and new
   versions without any modifications needed. They find the version
   automatically.
- The upgrade_MailScanner_conf command now preserves all your custom
   %variable% settings.
- Linux cron job scripts added to tarball distribution.
- Made the spam tag come before the virus tag on infected messages so that
   spam can be dumped more easily automatically.
- Added support for SpamAssassin version 3.
- Added new configuration options so that RBL's (and SpamAssassin) can have
   their network checks disabled is they fail more than a certain fraction of
   the time. This is very good for finding unreliable RBL's that don't always
   fail and are therefore not found by the "max timeouts" settings.
- Added new configuration option "Ignore Spam Whitelist If Recipients Exceed"
   to catch spammers who deliver messages to lots of recipients, including
   one recipient who chooses to receive all their spam.
- Added link to the Ellen MacArthur Trust to the home page. Please support
   this charity, they perform excellent work in an area that is very close to
   my heart.
- Improved update_virus_scanners so it ignores the lock if it is old.
- Added scanner name to log output from library-based virus scanners modules.
- Improved building of SRPMs so they work on all RedHat and SuSE versions.

* Fixes *
- Debian fix for their different dir structure causing problems with
   update_virus_scanners.
- Fixed problem where some HTML messages from Yahoo did not have the clean
   message signature added to their HTML portion.
- Fixed problem with some systems not rewinding file extraction directory
   properly.
- Fix to avoid problems in Qmail with regular expression match which reading
   Qf file.
- Messages with too many attachments should get a proper report now.
- Quarantine and Incoming Queue group memberships should now work properly
   for non-root users.
- Now only signs text/plain and text/html sections, so some PDF files and
   Outlook messages are not corrupted.

P.S. MailScanner has now passed 1/4 million downloads!
