The information in this article applies to:

- Microsoft Exchange Server, version 5.0 
-------------------------------------------------------------------------------

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,

MORE INFORMATION

using the Exchange Administrator program.
