SYMPTOMS
When you use Exchange 2000 Server to receive external mail, Exchange 2000 may not deliver the external mail. Event ID 9002 and Event ID 9004 (Categorizer Hard Failure) may occur, and you may receive the following non-delivery message: In Exchange 2000 RTM:

NDR:

Final-Recipient: rfc822; @ .com

Action: failed

Status: 5.0.0

In Exchange 2000 SP1, Exchange 2000 SP2:

NDR:

Final-Recipient: rfc822; @ .com

Action: failed

Status: 5.3.5



CAUSE
This behavior can occur if the Internet message format entry is missing or invalid.



RESOLUTION
To resolve this behavior, check the Internet message format, which is located under Global Settings in Exchange System Manager. Make sure that there is a Domain=* entry, which is normally present by default.
