SYMPTOMS
The Microsoft Mail Connector interchange (MSMI) will not process messages addressed to recipients if the recipient's address exceeds 256 characters. Typically, these messages would have been received by the Internet Mail Service and then forwarded to the MSMI. The message will remain in the MTA queue to the Microsoft Mail Connector. Additionally, the following errors are logged in the Application Event log:

Event ID 2380

Source MSMI

A memory access violation has occurred that prevents further processing of a message. The access violation that occurred is an attempt to read from 0x632e6262. Please refer to the immediately following event(s) logged by MS Mail Connector Interchange for more information on the message that could not be processed. (Exception address: %2.)

Event ID 2451

Source MSMI

MS Mail Connector Interchange has failed processing message from Exchange. The message is left in the delivery queue. Use the MS Exchange Administrator to view the details for this message or remove it from the queue. This error message will be logged again the next time MS Connector is restarted if the message is not removed from the queue.



CAUSE
The MSMI is unable to parse recipient names longer than 256 characters.



STATUS
Microsoft has confirmed this to be a problem in Exchange Server version 5.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base:

MORE INFORMATION
To remove messages stuck in the MTA queue to the Microsoft Mail Connector, you must shut down the MSMI service and then delete the item from the MTA queue using the Exchange Administrator program.
