Thanks Brett. Is that analyssis for inbound/outbound or both? What do you do with things marked spam? I ask because it would make an excellent model for legit mailers to use SA to: 1) Keep abuse down by not allowing spam runs out of server. 2) Help keep legit mail from getting tagged. Now granted this is exactly what spammers are trying to do as well. But if more legit companies also did this, it would cut down on FPs for the rest of us. (Like learning to not send HTML only newsletters!) It also sounds like a nice chapter for an O'Reilly cookbook ;) --Chris
