I have just released a new beta-test version, 4.40.4.

This release is mainly for fixes to the Bayes database rebuilding, and
for more Postfix testing.

I have replaced my spam.assassin.prefs.conf and now use a very slightly
modified version of the one provided by Fortress Systems (thanks
Steve!). The change is to maintain compatibility with all previous
versions that keep their Bayes files in ~/.spamassassin.

Also the RAR archive handling is greatly improved.

The full Change Log is:
* New Features and Improvements *
- The "clamavmodule" scanner cannot unpack archives of RAR version 3.
  2 new configuration settings allow you to unpack the latest RAR archives
  for testing by the "clamavmodule" scanner.
  It also enables the contents of the RAR archive to be checked for illegal
  filenames and filetypes, and also to see if they are password-protected.
  Unrar Command = /usr/bin/unrar
  Unrar Timeout = 50
- "Allow Password-protected Archives" can now be a ruleset when using the
  clamavmodule virus scanner.
- Multiple "Subject:" lines are removed. The 1st one is kept.
- If the "Unrar Command" is defined and points to an executable program,
  it will automatically be used by the "clamav" scanner. No -wrapper
  tweaking is needed to do this any more.
- You can now use shell environment variables such as $HOSTNAME or
  ${HOSTNAME} in MailScanner.conf and its relatives.
- More improvements to the phishing net.
- More additions to the starter file.
- Removed my spam.assassin.prefs.conf file in favour of the one from, with just enough changes to produce an identical file
  layout to my previous versions.
- Re-enabled ALL_TRUSTED rule after comments from Matt Kettler. Thanks!
- Added long comment about ALL_TRUSTED rule, many thanks to Matt Kettler.
- Improved screen behaviour of RPM-based init.d script.
- Greatly improved RAR archive handler, thanks to Rick Cooper.

* Fixes *
- Fixed problem with missing Attachment-Warning when encountering a virus
  that is both silent and non-forging.
- Improved output format of Sender warning, and removed duplicate lines.
- In IPBlock facility, changed MTA dsn to 451 to temporarily refuse the
  connections, rather than the total block it used to do.
- Removed erroneous log output from SpamAssassin bayes-rebuilder.
- Postfix problem fixes.
- Fixed SpamAssassin Bayes database rebuild timeout problem (hopefully!).
