Well, the remote side apparently had "unknown_local_recipient_reject_code = 450", which I am assuming had me retrying, I too had this setup this way until this afternoon. I've just sent to a different recipient and one that I know has "unknown_local_recipient_reject_code = 550" and in deed I received the bounce instantly. Does this mean that if a remote site has this set to 450 that I will keep trying for 5 days, or however long my "maximal_queue_lifetime" is set for? What do I do in the case of misconfigured (are they?) MTA's? Thanks, .vp
