SYMPTOMS

Under certain circumstances The Microsoft Exchange Message Transfer Agent (MTA) may terminate unexpectedly with the following error message:

   message NMI2050: Internal Processing Error, severity 16

          (BASE XFER-IN(21) Proc 9) 06-27-96 02:03:05pm

CAUSE

This problem occurs when the MTA has received a corrupted or incorrectly encoded message from a remote MTA. For example, if the MTA receives a message, the actual content length of which is "x," but the encoded content length was "100x", the MTA will terminate unexpectedly with the Event ID 2050.

RESOLUTION

In order to resolve the problem, the corrupted or incorrectly encoded message must be removed from the remote MTA's queue, and the Exchange MTA must be restarted.

Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 4.0 Service Pack 1 (SP1) and Service Pack 2 (SP2).
