The problem with accept-then-bounce is that the message ends up stuck on the *receiving* server. This is NOT a good way to handle email- especially considering quite a bit of spam doesn't have a valid return address of ANY kind ANYWHERE in the message, and viruses may technically have a valid return address... but not a *correct* one. On high-load mail systems (ie, multi-million messages/day/server), this can mean a LOT of dead-end messages stuck in the queue for days on end. -kgd -- "Sendmail administration is not black magic. There are legitimate technical reasons why it requires the sacrificing of a live chicken." - Unknown
