It supports all the current antispam technologies Whitelists blacklists Spamassassin DNS block lists Razor, Pyzor, and DCC Bayesian filtering Custom tests to various characteristics both in the raw form or decoded Greylisting Clam antivirus included And you can have it do an LDAP lookup against your Exchange box to validate email addresses, this has been a life saver for me as the lastest rash of both spam and viruses like to forge invlid users for the domain.
