1/8/2007 New in Version 4.62.9-3
================================
* 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
  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
  www.peregrinehw.com/downloads/SpamAssassin/contrib/KAM.cf
  To download this automatically every night, fetch
  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).
5 Added "custom" spam action, which takes a parameter. This is passed into the
  CustomAction function in CustomAction.pm in the CustomFunctions directory.
  This can be used to implement anything your heart desires, depending on the
  contents of a message.
7 When clamav, clamavmodule or clamd parsers are being used and new setting
  "ClamAV Full Message Scan" is set to "yes", pass each of the entire
  messages to ClamAV as well as the attachments so that the signatures that
  detect spam can work reliably. This is set to "no" be default as it has a
  speed impact.
7 The watermark options have been tweaked and renamed a bit, and one new
  feature has been added. "upgrade_MailScanner_conf" will show you the renames
  and the new feature is designed to save resources on sites with more than
  1 MailScanner. Currently, if you have a message delivered to a secondary MX
  (with MailScanner) which relays mail to the primary MX (also with
  MailScanner) for delivery to users' mailboxes, the spam checks will be
  done twice; this is a waste of resources. The new setting "Check Watermarks
  To Skip Spam Checks = yes" will remove this waste by skipping the spam
  checks on the primary MX as the secondary has already done them.
7 "Virus Scanners = auto" will detect multiple types of ClamAV installed and
  tend towards the most useful one. It will use clamd else clamavmodule else
  clamav. This helps if you have all 3 installed, which is quite likely.
8 Greatly improved "MailScanner --lint". It now actually tests every virus
  scanner that you have installed, and checks that they can successfully scan
  a message containing the Eicar test-virus pattern. It reports the results
  from each scanner and warns you about checking any that are not reported.
9 Added check to "MailScanner --lint" to check envelope_sender_header in
  spam.assassin.prefs.conf is correct and matches MailScanner.conf.
9 Added new setting "Use Watermarking = yes" to give overall control of all
  watermarking features.
9 Fixed error with "MailScanner --lint" when not using sendmail.

* 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.
5   Fixed 2 bugs in MSRBL clamav-signature handler. Thanks to UxBoD.
6   Fixed bug from October 2006 involving McAfee finding infections in headers.
7   Fixed bug when unpacking TNEF files with external decoder.
7   Fixed 'monitor files' check in upgrade_MailScanner_conf so it doesn't check
    inadvertently when doing an upgrade_languages_conf.
7-3 Fixed bug in full message file creation in scanning dir as permissions
    were wrong.
9   Added use POSIX to top of MessageBatch.pm so WNOHANG is defined.

Wie immer wird Seceidos in den nächsten Tagen die passende Version des FreeBSD Ports zur Verfügung stellen.
