I have an Exchange 2003 frontend server and a backend server. Emails are getting stuck in the backend queue that's located on the frontend server. If I forced connection and fiddle with it some will push through... But... Most stay in the queue. On the backend server it seems the emails are getting stuck in the local delivery queue I've restarted the services and even each server... Still no luck. What else can it be? Where do I need to look?
