You can try putting a linux box running spam assassin in the front of
the firewall or even behind it have that do your mail filtering then
forward the mail to the mail server minus the spam (including
viruses) currently my mail server is blocking and removing all
instances of my doom, I have not had one out break in our domain with
that software yet. I have all the spam forwarded to an account for
reviewing to make sure my filters are not blocking anything
important.

If you want to catch the attachments you can try using mailsnarf and
filesnarf it is a package in the dsniff suite. Though that wont stop
the mail from coming in it will store a copy of the file on that box.

Subject: File Catching Firewall?

Was asked to look into maybe putting in a Linux box in front of our
mail
server to stop the massive amounts of email attachments we have been
receiving as of late due to 'MyDoom'. We currently have a WG
FireBoxII and
software on our Mail Server that is supposed to be catching
everything, but
with so much coming in it's missing alot. I was wondering if anyone
had any
ideas on some type of solution for this, all input is greatly
appreciated.
Thank you.
