The Microsoft Exchange Server Microsoft Mail interchange (MSMI) stops and may log the following events in the Windows NT Event Viewer Application log:

   MSExchangeMSMI Event ID 2380:
   Source: MSMI

   processing of a messsage

CAUSE

The MSMI is attempting to log an event for an NDR of a message with invalid sender and recipients.

WORKAROUND

Resetting the INQUEUE3 Key and Mbg file on the shadow post office will allow the MSMI to restart, but will result in the loss of any messages in the queue.
