SYMPTOMS
When you send a message from a Defense Messaging System (DMS) client to an SMTP address, the message may not be successfully processed. The message gets stuck in the outbound Internet Mail Service (IMS) queue for the message transfer agent (MTA) on the server.

An error message resembling the following may be generated by the IMS in the Application Event Log:   MSExchangeIMC Event ID: 4122 An error occurred while retrieving the originating address of a message to be delivered.

Since the originating address is needed for mail delivery, the mail cannot be delivered. The message that was being processed has been moved to the "BAD" folder. Use the appropriate utilities found in the SUPPORT directory of your Exchange CD to view and manipulate these messages. When you attempt to view the message within the MTA queue for the IMS, the MTA service may stop with an error message resembling the following in the Application Event Log:   MSExchangeMTA Event ID: 2051 A fatal internal MTA error occurred. Contact Microsoft Product Support Services. An illegal GET from element BCC62C01 occurred at offset 12359. [BASE SUBMIT 16 67] (16)



CAUSE
If the X.400 O/R address of the originator contains an X.500 distinguished name (DN) in the domain-defined attribute (DDA) field, the IMS encapsulates the X.400 O/R address instead of using the SMTP proxy, resulting in the stated behavior.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0.

This problem was corrected in the latest Microsoft Exchange Server 5.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
