Greylisting for Exchange 2003 (2007 too)

Ealier in June I had blogged about the subject of Greylisting as raised by a colleague.  Since then I have taken a curious interest in the Anti-Spam technique which takes advantage of SPAM’ers lack of RFC compliance at the MTA level.  Here are some new resources I’ve discoverd including a great post by a great Exchange MVP who uses SBS, Daniel Petri:
