Unusual Queues in Exchange

I use SBS 2003 (R2). I noted an unusual amount of internet activity and looked to exchange. I the Server, servername, Queues menu I find about sixt odd queues list after the usual ones with the labels Small Business SMTP connector - then a domain name (not mine & fifferent in each case. Each has 1 message in it from postmaster at my domain (varying message sizes). Each indicates it can't reach it's connection. By freezing all of these, internet activity has died off. I suspect something odd, although could be NDR's for various spam messages, although I think I've managed to kill off NDR's.

How can I delete these queues?

Thanks, Have done that & queues are disappearing. Are you able to throw any light on what is causing them, and whether I need to have any cause for concern?

Did you read my comments regarding backscattering?

And the way to prevent it is implementing the Filtering Unknown steps that Sembee provided.
