The Exchange 2000 message transfer agent (MTA) may generate an access violation and stop, which requires you to restart the MTA. A message causes the access violation while the MTA is decoding the relayed message. If Application Protocol Data Unit (APDU) logging is enabled, the MTA stops before the message is written to the Bf0.log. You must remove the DBxxxxxx.dat file that contains the message from the Mtadata folder before you can successfully restart the MTA.
This problem can occur because a Siemens Mail.X MTA uses encoding for the Deferred Delivery date attribute that is different from the encoding that the Exchange MTA 2000 expects.
