While for virus you may argue that there is a clear cut between clean and infected message, it is far from being as clear for spam. What you consider spam and would reject may be completly valid for another user. So, rejecting spam during smtp-dialog is risky, that is why most resolve to some sort of quarantine, and that is when amavis comes handy. Best regards, Olivier
