STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in Microsoft Exchange Server 4.0
U.S. Service Pack 2. For information on obtaining the service pack, query
on the following word in the Microsoft Knowledge Base (without the spaces):
MORE INFORMATION
When a message enters the MTA queue, it is assigned a unique identifier
(MTSID in the message details in the MTA queue) by the MTA. When the
message leaves the queue, the identifier is stripped and it might be re-
used for another message that enters the queue.
With Microsoft Exchange Server version 4.0, there is an issue where
multiple messages might be assigned the same MTSID number. This ID
collision will then cause the transport session to shut down. This causes
messages to hang in the queue until one of the messages with the duplicate
ID leaves the queue.
