We have an Exchange 2003 server and we are starting to experience problems where Email is being sent and then delivered up to 3 hours later. These are local users inside the domain. When I track the message I see
1:37 SMTP Message submitted to Categorizer
3:09 SMTP Message scheduled to retry categorization
4:09- SMTP Message Categorized and Queued for routing
Delivered to multiple recipients
We are running McAfee Groupshield 7.0. We run GFI Mail Essentials on a SMTP box in our DMZ so I do not believe that is the problem as local Email should not hit that at all.
Thanks in advance.
