The issue we are experiencing is that various mails are stuck in the local delivery queue of our Exchange 2003. Some emails seem to be flowing through but a large majority are stuck retying and never go through.
The emails are from various domains.
I have run:
isinteg -s SBS -fix -test alltests (No errors)
eseutil /p (No issues)
There are no errors logged in the event viewer either.
Server is running Symantec Endpoint Protection - I've seen various posts where people suggest uninstalling this but all result in no change of status with regards to the mail. (I have not yet tried this)
Does anyone have any suggestions?
