Release 4.63.2 beta

Hash: SHA1

I thought it was about time for a new beta. So I've just released 4.63.2.

The main new points compared to the last beta are:
- -- New setting "Check Filenames In Password-Protected Archives = yes". 
Useful if you allow password-protected archives to a few of your 
developers, and they need to exchange executables in them.
- -- New setting "Include Binary Attachments In SpamAssassin = no". You 
can use this option, in conjunction with the small SpamAssassin patch 
applied for MCP to work, to add to the spam checking the feature that 
MCP has over it, in that it will process all attachments for spam 
content, not just the text and HTML.

Download as usual from www.mailscanner.info.
Please check that the new features all work correctly and that the bug 
fixes have actually fixed any problems you were having.

Thanks!

The full Change Log is:
* New Features and Improvements *
1 Improved init.d script, so that 'service MailScanner restart' or
  '/etc/init.d/MailScanner restart' runs faster. It pauses for just long
  enough for the old MailScanner to die gracefully, and starts up the 
new one
  as soon as the old one has died. Previously, it just waited for a fixed
  length of time which was much longer than needed for most people.
1 Improved tar installer so the directory created for MailScanner 
includes the
  build revision number as well as the main version number.
1 Improved phishing net logging to log entire real URL not just hostname.
1 Improvement to update_spamassassin to stop cron-generated mail.
1 New setting "Phishing Bad Sites File" which is a live continuously-updated
  list of known bad sites that have been reported to various mechanisms 
around
  the world. Please don't ask me for more information as I can't give it to
  you, but every site on the list has been manually tested and the list 
can be
  relied upon. Your installation should update this file every hour.
  NOTE: Run upgrade_languages_conf after installing this upgrade!
2 Reduce default "Restart Every" time to 2 hours so that updates to the
  known bad phishing sites list are re-read more frequently.
2 Added *.fdf to the list of dangerous filenames. Opening a .fdf file can
  cause the loading of any file on the internet into Adobe Acrobat.
2 Added 2 new variables to the sender reports: $size = size of message 
in bytes
  and $maxmessagesize = maximum allowed size of this message in bytes.
2 Added new setting "Check Filenames In Password-Protected Archives = 
yes" so
  that the filename checks can be suppressed on encrypted archives to allow
  a few people to get exe's and so on through the mail as part of their
  business needs. Normally leave this setting at "yes".
2 Added new setting "Include Binary Attachments In SpamAssassin = no" which
  can be used to tell SpamAssassin to look at all attachments, not just the
  ones containing text (or HTML, etc) which is its normal behaviour.
  Changing this setting to "yes" will have no effect without a patch to the
  SpamAssassin code, which you can fetch from
  http://www.mailscanner.info/mcp.html#patches
  It will slightly slow down SpamAssassin some of the time, and is therefore
  disabled by default.
  This can be very useful if you want to look for rude or derogatory content
  in messages, and do not want the huge speed impact of using MCP. It can
  successfully scan the content of Microsoft Word documents, for example. It
  won't be effective on PDF files however, as these are compressed 
internally
  so there is no readable text anywhere in the file.

* Fixes *
1 Improvement to phishing net to allow HTML tags with contents split over
  multiple lines.
1 Changed options to ClamAVmodule so it doesn't hit false positives with the
  phishing and scam email detection signatures.
1-2 Fixed bug where --lint gives "MailScanner.conf file not found" error.
2 Stopped writing a PID file when "MailScanner --lint" is run.
2 update_spamassassin no longer produces any output, so no crond email.
2 Fixed bug where clamavmodule scanner name wouldn't always be logged 
correctly.
2 Bugfix in ZMDiskStore.pm ZMailer support from Leonardo Helman.
