SYMPTOMS
In some cases, a third-party X.400 message transfer agent (MTA) may send an invalid message to Exchange Server. Depending on the amount of corruption, the following events may be written to the Windows NT Server application event log:

Event ID: 200

Description:

X.400 Service Event, severity 14

(MTA XFER-IN(12) Proc 102)

Transfer-In failure, error in received APDU

Error detected at offset 0

Internal qualifier 0

Node label

PDU dump reference 14

NOTE: Event ID 200 indicates a corrupted field in the X.400 P1 message header. You can use the PDU dump reference given in this event to identify the corrupted message in the Bf0.log log file.

Event ID: 2124

Description:
