Since the greylisting went into effect last Wednesday morning, I have not received a single spam message, either marked or unmarked, through my mail.msu.edu account. Prior to the change I was getting five or ten per day, so I would have expected 25 to 50 during those five days. My MSU mail is forwarded to an Exchange server, where Microsoft's IMF filters out the most obvious spam so it doesn't even reach my mailboxes. I suspect that without this additional filtering I would still be getting some spam from my MSU account, but the improvement from the greylisting is still pretty impressive. (During this period I did get a single spam message addressed directly to my Exchange mailbox, which of course is unaffected by the greylisting.) Are others also seeing a dramatic improvement? --Chris ============================================== Chris Wolf Computer Service Manager Agricultural Economics [log in to unmask] Michigan State University 517 353-5017
