MailScanner

Fedora 10 is supported. tnef was upgraded to 1.4.5. A patch was added to ClamAV and SpamAssassin to make the Mail::ClamAV Perl module handle ClamAV 0.94 correctly. mcafee-autoupdate was fixed so that it will work properly.

There is now an alternative phishing net which is
less strict than the original. It knows all about
top-level and second-level domain names in
countries around the world, and will allow a link
that points to the same company as the text it
claims to be. This is particularly useful for ISPs
who cannot use the phishing net because it caused
too many false alarms. Support for Sophos 5 has
been added. Contents of gzip-ed archives will now
be checked for filenames and filetypes. Detection
and removal of Web bugs was improved.

A "Use TNEF Contents" feature was added, which you
can use to add to a message the attachments which
are held in the "winmail.dat" file in an "Outlook
Rich Text Format" message.

There are great speed improvements, often as much as a 40% speed improvement. Virus scanners are automatically detected. No configuration is required on sendmail systems. A UU-decoder was added to allow filename and filetype traps in UU-encoded files inside attachments. Many command-line options were added to the "MailScanner" command so you can test your configuration, evaluate rulesets, and debug your installation without have to set the debug options in MailScanner.conf.

This version is noticeably faster than before. File name and file type restriction rules are also greatly simplified, so everyone can actually understand it.
