I have a queue that fills with Internet Mail SMTP Connections and they just sit there for days. How do i prevent this from happening? Also would blackholeing the non deliverable mail do this? thanks

I'm guessing you are trying to send NDRs for undeliverable messages. Since most of these are going out to the forged from addresses on spam, most of the addresses are invalid, those that are valid simply annoy unrelated third parties. You should disable sending NDRs to prevent your server becoming blacklisted by other ISPs and to reduce the undeliverable mail held in your queues. There are different methods of doing this depending on which version of Exchange you are running. For 2000 or 20003: http://support.microsoft.com/kb/294757/ You might also want some more information on problems with NDRs and Auto Responses: http://www.spamcop.net/fom-serve/cache/329.html
