I know that's not compliant, but a real mail server would have got the 5XX and so (mainly) wouldn't retry, and a spammer would have their connection terminated.
Is there any real downside to this? (one I can think of: mailing-list broadcasts would be slowed down due to retries if invalid addresses were present...) I knew things like this would eventually happen. Spammers basically have infinite resources, they can deliver us a LOT of hurt when they wish to. I can think of a lot worse things they could do - and probably will :-( -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
