SYMPTOMS
You may experience all the following symptoms intermittently on one or more of your Microsoft Exchange 2000 servers:  Message delivery is significantly delayed. A message may take up to 45 minutes or more to be delivered, even to a recipient who has a mailbox that is hosted on the same server. Messages remain in the Messages waiting to be routed queue of the SMTP virtual server.  A message sender receives a non-delivery report (NDR) with a status code of 5.1.0, and the following event is logged in the application log of Event Viewer: Event Source: MSExchangeTransport

Event Category: Categorizer

Event ID: 9004

Date:

Time:

User: N/A

Computer:

Description: Categorizer encountered a hard error while processing a message. While processing user 'ex:/O= /ou= /cn=Recipients/cn= ', the function 'HrHandleOneOffOrContact' called 'HrEncapsulateAddress' which returned error code '0xc004055d' (Unable to route the recipient address). 



CAUSE
This problem occurs if the Exchange 2000 Server Message Categorizer component encounters an error when it tries to encapsulate an e-mail message address. A 5.1.0 NDR is generated, even if the error was one that can be retried.
