You wouldn't really use a firewall to block spam. At best your firewall could deny connections from known open relays, but it is best to allow the mail server to impliment your spam filtering.

Hi
yes exchange server can work with linux firewall.
2ndly if u can stop spams with send mail biltin features .
firewall just fillter ip packets . and block data with spooed ip headers,trojon attacks etc

U can use microsoft ISA server as a firewall for your private network where mail server located. and witl ISA server Messge Screener you can fillter in coming mails.
