I have a exchange 2000 server that is getting ready to be migrated to 2007. Unfortunatley I am having a queue problem. The queue is showing thousands of emails pending to addresses at yahoo.com.tw. I delete the queues using aqadmcli.exe and the queue starts filling up again to thousands of addresses at yahoo.com.tw I have logging turned on and am currently scanning all the systems for viruses. Is there any way to find where these emails are comming from? I have checked relay and it is tuned off. I have the relay tab set to all except thre list below and allow all computers that authenticate checked. Any help would be apreciated.
