jassyca -> RE: Mysterious Spam Queue (25.Nov.2006 1:38:06 PM)

Just my 2 cents but when I find that sort of stuff in my outbound queues, it usually turns out that it's an NDR and not my server relaying junk. In other words, it's a "legit" message (even though it's going to a spammer). However, since the message is going to a spammer and spammers never accept messages, it appears "stuck".. until Exchange finally gives up on trying to deliver it. Probably one of your ex-users signed themselves up to receive that crap and now that the user is gone, Exchange is dutifully trying to let the sender know the mailbox does exist anymore but of course the spammer doesn't give a rat's a**. I've got mailboxes that haven't existed for 5 years that still get crapmail. [:'(] If you only see one spammer domain listed in your outbound queue, you must be doing something right or else you're lucky as hell. If the former, would you please tell us your secrets? [;)] Just incase you ask: yes you could turn off sending back NDR's to spammers but that would include not sending them to non-spammers as well because it's one of those all-or-nothing things.
