Exchange Server 2003 SMTP Queue Problem
Posted on 2006-06-22
I have an Windows 2003 Advanced Server running Exchange 2003 SP1 on it. It is not a domain controller. Mail works perfectly on it 99% of the time. All Windows updates have been done. It has Symantec Mail Security and Symantec for Exchange running with all the Symantec reccommended exclusions for the email files and folders done. Mail flows thru the SMTP Virtual server just fine. Until the queue grows to 2000. Then it refuses to accept any more smtp mail until one of the existing queue items releases. It seems to have a limit of some kind on the number of queue items it can process. I cannot find a setting to change this. Has any one run into this? Is there asetting I am missing? Maybe an IIS setting?
My current solution is to simply clear the queue. But I know I probably loose a couple of legitimate NDR's when I do that so..........
