This is to announce 1.20rc1 - a RELEASE CANDIDATE for 1.20

Some major additions have gone on within Qmail-Scanner-1.20rc1, making Q-S
much better at blocking suspect e-mail as a POLICY decision instead of
relying on Anti-Virus software. e.g. Qmail-Scanner-1.20rc1 stops the likes
of KLEZ dead without the need of an AV package.

This is NOT the final release of 1.20 - it's a RELEASE CANDIDATE. It has
been in operation here for some 5 months, and I feel it shouldn't cause
anyone any problems, but due to some design changes I am unwilling to state
it's a full release until I get some feedback about it :-)

So for those willing, I'd like you to TEST this release out, and get back to
me with any performance issues or bad decisions being made by the new code.
When the all clear is given, 1.20 will be released.

[remember: to really test it, you have to "./configure --fix-mime 2" to get
the really cool new features ;-). In 1.20, these features WILL BE ENABLED BY
DEFAULT]


New features include:

* "--unzip" disabled by default now. This means Q-S now relies on the AV
  systems to unzip the files, and also means that if you block (say) .EXE
  files, they can now get in via putting them within a ZIP file. If you want
  the old behaviour, use "--unzip yes" again. 

* Better logging detail - so you can tell what is quarantining what.

* This release candidate has added some simple MIME parsing that captures
  quite a few viruses/trojans. Since it may also catch some valid mail in an
  unusual layout, it is not enabled by default. To test (and *please*
  do!!!), you need to set "--fix-mime 2". Please notify the list as to any
  problems, as the intention is to make these checks part of the standard
  configuration by 1.20 release...

* Q-S now skips virus-scanning messages that are either text/plain 
  or non-MIME/uuencoded. This will speed things up a tad.
  
* SpamAssassin now sets the spamc "username" field to the recipient address.
  This only happens if there is ONE recipient. 

* Block messages with Windows executables that are *not* of MIME type
  application/* Never seen in the wild unless they are viruses. This may
  block some bogus mail that is otherwise valid, so you can only get this by
  setting "--fix-mime 2" when configuring.

* Explicitly block double-barrelled filenames which end in known Windows
  "executable" stype extensions - such as "file.doc.pif".

* Archiving now supports archiving only mail to or from a regex
