> Examples of a couple of the type of bouncebacks I get: > > http://www.game-point.net/misc/bb1.txt > http://www.game-point.net/misc/bb2.txt First one: > Return-path: <ha...@doctor-china.org> > Envelope-to: evaluatio...@game-point.net This isn't a valid bounce message to begin with: it should have had the null sender (MAIL FROM: <>). Second one: > Return-path: <> > Envelope-to: ro...@game-point.net Had you used SRS, this convo might have looked something like: > Return-path: <> > Envelope-to: srs0=+fzygofe=5i=game-point.net=ro...@game-point.net Which, after validation at MTA level, you would then have accepted. And soon as the MTA came in at: RCPT TO: <ro...@game-point.net>, you would have rejected it (for being unsigned). - Mark
