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?
