We run procmail rules for server-side spam filtering, using dmail as the delivery agent for MIX format. Generally this works well.
Wouldn't spam filtering at the smtp level be more effective and cause less traffic? It's important to be able to reject a message asap, preferably before any data goes through (grey listing, rejecting certain IP-addresses, etc.). So you have the least possible waste of resources.
With procmail the spam email already has been accepted, handled by MTAs and is about to be delivered to the recipient, at which time it decides to reject it. That kills one of the main benefits of filtering, decrease of useless traffic.
