Subject: RE: spam questionI have never heard of filtering spam at the firewall. How could a firewall possibly do that? Unless of course you know who the culprit senders are, but that changes continuously.

Subject: RE: spam question
It's also a waste of resources as the mail still has to travel through the firewall, into the IMC, get routed to dev null. Better to block them at the firewall (if possible) and return them a 5xx error. Dropping the request (as some do) returns a 4xx error so the mail will queue on their systems and retry.
As too why they would have a read receipt is beyond me. Most spammer could give a damn if their mail gets there or not. They are charging by the piece sent, not delivered. Spam houses take the add, merge it with a database of names and open up the mail cannon. Relayers wouldn't want a receipt anyways. That would give me a way to go after them directly rather than try to get the open relay to shut his hole.
