I have Exchange 2003 on Windows 2003 server. I am concerned about the number of Queues that I get on my Exchange server. Right now I have over 3600 queues with some of them containing as much as 150,000 messages. Most of the messages are in retry and are going to no existing internal accounts. My bad mail is averaging about 62,000 messages a day according to the MS Best Practice Tool. I have checked to make sure my exchange server is not set up for open rely and it is not according to MS article. If any one has any ideas as to what would be causing this.
