A fine point that I don't see mentioned much is that REJECT-ON-SMTP-DATA has the nice side effect that if it's real mail, the *sender's* MTA will generate their bounce for them, and if it's a spammer, they'll ignore it. So you get the best of both worlds, which seems an excellent reason to go through the effort of setting it up that way. Cheers, - jra -- Jay R.
