Bad messages clogging up the SMTP mail queue

[CHokKA]

Hi all.

For some reason, on our Exchange 2k server, when a bad message gets sent (ie bad recipient, server timeout on recipients end etc) the message seems to sit in the queue holding up every other message that's being sent. This can go on for a few days until the non-deliverable rule kicks in and deletes the bad message. Is there anyway I can configure the server to shift bad messages to another queue (which I will need to create) so that all the other messages can get sent from the defualt queue? I don't really want to delete the message straight away because sometimes it's just a server timeout or a temporary glitch.

Thanks in advance.
