The latter is what would screw that as a solution for most I think :( best thing to do is to make sure list is FULLHDR or SUBJECTHDR I think, and put list on full moderation so the listowner can forward the forged posts to the sender's provider's abuse addresses until the nut loses his/her provider for doing this.. and as you said, most would boot them pronto. BUT, with aol and other throw away accounts, would be a no brainer to start over :( Maybe just a live with it kinda deal and forward each occurance to the abuse addressesses of the forger with full headers included. ...Cleo [log in to unmask]
