Spam - Copperfasten Mail Firewall Appliance
They are set up in a similar architecture to our previous home grown solution and have a similar software set up using postfix, amavisd-new, spamassassin, and clamAV.
However this solution is more sophisticated and offers many new advantages to mail users
- suspected spam/virus is quarantined before it reaches your mailbox
- ability to manage personal white lists and black lists
- receive scheduled reports detailing quarantined mail
There is an faq page here which explains the new reports and how to use them.
