Add mailscanner 4.21.9, a powerful virus/spam scanning framework
for Sendmail and Exim.
MailScanner is a complete e-mail security system designed for use on
e-mail gateways. It protects against viruses, and detects attacks against
e-mail client packages (such as Outlook, Outlook Express, Eudora). It can
also detect almost all unsolicited commercial e-mail (spam) passing through
it and respond to all incidents in a wide variety of ways.
Not only can it scan for known viruses, but it can also protect against
unknown viruses hidden inside e-mail attachments by refusing entry to
attachments whose filenames match any given pattern. This can include generic
patterns that trap filenames attempting to hide the true filename extension
(e.g. ".txt.vbs").
