Beta release 4.62.4

[Julian Field]

I have just released a new beta, 4.62.4.

This contains some bug-fixes, a few new minor features such as Kaspersky 
KAV4FS support, along with 2 major new ones:

1 - Addition of 4 new "store" actions, "store-nonmcp", "store-nonspam", 
"store-mcp" and "store-spam" so you can pick any particular bit of the 
quarantine you want as a message action.
2 - Addition of the "SpamAssassin Rule Actions" setting which is 
documented in the MailScanner.conf file.

The documentation of SpamAssassin Rule Actions from MailScanner.conf is 
this:
# This next setting is very powerful. It allows you to adjust the list of
# actions taken on a message by adding or removing any action or actions,
# depending on what SpamAssassin rules it matched.
# It can be used to replace the functionality of MCP, but without the large
# processing overhead that involves.
#
# The setting consists of a comma-separated list of 'SA_RULENAME=>action'
# pairs, where 'SA_RULENAME' is the name of any SpamAssassin rule (or
# meta-rule), and 'action' is the name of any of the actions listed above
# the 'Spam Actions' configuration setting or the word "not-" preceding any
# of the action names.
# Preceding the action name with "not-" as in "not-deliver" or "not-forward
# user at domain.com" will cause the action to be removed from the list of
# actions that would normally be taken on this message.
# If you want to execute multiple actions on 1 rule, simply specify multiple
# 'SA_RULENAME=>action' pairs.
# Example: Setting this to
# SpamAssassin Rule Actions = FROM_BOSS_WIFE=>not-forward 
secretary at domain.com
# would result in mail from the boss's wife not being forwarded to the 
boss's
# secretary, which would be useful if the non-spam actions for the message
# included forwarding to the boss's secretary.
#
# Combining this with a ruleset makes it even more powerful, as different
# recipients and/or senders can have different sets of rules applied to 
them.
#
# This can also be the filename of a ruleset, in which case the filename
# must end in ".rule" or ".rules".


The full Change Log is this:

* New Features and Improvements *
1 Improved non-Linux installer.
1 Improved Linux installer.
1 Updated OpenBSD installation guide. Thanks to Jeremy Evans for this.
1 Upgraded MIME::Base64 to 3.07.
1 Improved error reporting for clamd permissions problems. Thanks Rick.
2 Added SAUPDATEARGS to /etc/sysconfig/MailScanner and
  /usr/sbin/update_spamassassin. For a good use of this, see
  http://daryl.dostech.ca/sa-update/sare/sare-sa-update-howto.txt and search
  for "HOWTO" in the Subject: line of the MailScanner-discussion list 
archive.
  This process replaces RulesDuJour entirely.
  Another good ruleset to add to your setup is
  http://www.peregrinehw.com/downloads/SpamAssassin/contrib/KAM.cf
  To download this automatically every night, fetch
  http://www.mailscanner.info/files/4/KAM.cf.sh and put it in 
/etc/cron.daily
  and make it executable (type "chmod +x /etc/cron.daily/KAM.cf.sh").
3 Added "Known Web Bug Servers" so you can blacklist images from known 
servers
  of web bug services.
3 Added functionality of "milter-null" to MailScanner so you no longer 
need to
  run this separately. It is called "Watermarking" and there is a whole
  section for the settings in MailScanner.conf. They are
  Add Watermark = yes
  Skip Spam Checks If Watermark Valid = yes
  Watermark Header = MailScanner-%org-name%-Watermark:
  Watermark Lifetime = 432000 # in seconds, = 5 days
  Watermark Secret = SET-THIS-TO-A-SECRET!
  Also added Digest::MD5 to the required list of Perl modules, this is 
needed
  for the watermarking code.
3 Added optional image to the clean message signature. You can also use this
  to add an arbitrary image attachment to any message, if you so wish. The
  main point is to be able to have graphical HTML signatures on messages.
  The settings are
  Attach Image To Signature = no
  Attach Image To HTML Message Only = yes
  Signature Image Filename = %report-dir%/sig.jpg
  Signature Image <img> Filename = signature.jpg
4 Added support for Kaspersky kav4fs. Set virus.scanners.conf entry to
  point to /opt/kaspersky.
4 Changed default value to "Max SpamAssassin Size = 100k" as modern PDF 
spams
  are getting quite large, and PDFInfo.pm doesn't work with cropped 
messages.
4 Improved Clamd parser to handle Sane Security ClamAV signature databases
  which detect spam and so on from the contents of the headers, and hence
  find infections without attachment filenames. Thanks to various people for
  help with this, you know who you are :-)
4 Improved upgrade_MailScanner_conf so that it checks that the 'Monitors for
  ClamAV Updates' setting looks for inc and cvd files. Problems have 
recently
  been suffered by many due to the value of this setting being out of date.
  It doesn't automatically re-write their setting in case they have 
installed
  ClamAV somewhere odd and have customised it.
4 Changed 'Monitors for Sophos Updates' setting default value to point to
  appropriate file for Sophos version 5 and upwards, and have added check
  in upgrade_MailScanner_conf to ensure their setting now points to a new
  location. It prints a warning if sophos-av does not appear in the path.
4 Added configuration setting "SpamAssassin Rule Actions". This setting is
  very powerful and can be used to implement many things that MCP can do,
  without having the processing overhead of MCP. The documentation for it is
  in the MailScanner.conf file. Its power is limited by your imagination :-)
  Start combining it with rulesets and you can take (or _not_ take) any
  combination of actions dependent on any bit of content in the message 
or its
  headers. You could try out new SA tests by storing in quarantine every
  message that matches a new particular SpamAssassin rule (or meta-rule for
  creating more complex expressions).

* Fixes *
2-2 Fixed error in RPM installer.
2-3 Fixed error in update_spamassassin.
3-2 The watermarking code should do something now :-)
3-3 Rewrote the watermarking docs so they reflect the truth.
4   --lint now reads all the Custom Functions properly.
4   Bug in auto-zip fixed where attachments could be deleted without being
    added to zip. Thanks to Matt Hampton.
4   Bug with '-' in HTML attribute names confusing phishing net fixed. 
Thanks
    to John Wilcock.
