Virus software for email

With this new Mydoom virus attacks, I am glad that I have installed the following software:

amavisd-new

http://ftp.cfu.net/pub/amavisd-new/

This is a great software where it scans all mail coming into our server for spam and viruses. If it finds a spam or virus, it will quarantine the message and can notify the sender and receipient.

This is some add-on software to amavisd-new, that will quarantine the spam and viruses into a mysql database
