STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5.
MORE INFORMATION
If the Exchange Server MTA service stops on one server, Exchange Server versions 4.0 and 5.0 return an NDR to the sender and delete the message from the MTA queue when the message exceeds the retry limit and the retry intervals. This behavior changes in Exchange Server 5.5; the MTA keeps trying to send the message until the recipient server's MTA service is restarted.
