Subject: Filtering SPAM with Linux


Hello. I have a box with linux that is acting as NAT and Firewall (also
cache with squid and reverse proxy with pound).
I have an internal MS Exchange server that goes to internet 
via NAT, and
i dont have any chance of removing it, but i would like to filter the
incoming traffic to remove spam.
My net looks something like this:


INTERNET <---> x.x.x.x LINUX BOX 10.1.20.100 <---> 10.1.20.1 
MS Exchange

What can i use in the linux box? I have found things like 
MessageWall and
so, but i need better recomendations from people that already doed it.

Thanks!!
Ivan Hernandez
