We recently replaced a drive in our Exchange server and since then we have been getting numerous delay notifcations for outbound email. We eventually get undeliverables for those messages and are not able to send outbound email through our SmartHost. Although, we are able to receive inbound email w/o any problems. No problems sending/receiving internally.
We are using Xwall for Exchange server 3.4.2 running on Windows Server 2003 SP2.
Exchange is version 6.5 SP2 also running on Windows Server 2003.
