Grey listing is cool, and it is the one tool I have yet to use against spammers... The fly-by night guys drop the spam to you via a broken relay. This lets the mail come to you via a legitimate IP block that has not yet been added to anyones Block-list. Gray listing will definitely work very well against a misconfigured mail server.
I would love to front-end my mail services with an OpenBSD box... Thanks for the HeadsUp Magnus! Maybe I'll give that a try first, before putting in a C/R system. I'm not too hopeful though as Spammers do seem to adapt rapidly these days. We really need to press for smtp-auth to become the standard of the 21st century.
