The Exchange Server message transfer agent (MTA) may generate a delivery report (DR) or non-delivery report (NDR) with a content type that is set to an external value (2A 86 48 86 F7 14 05 01), which is Messaging Database Encoding Format (MDBEF). This can cause problems for non-Exchange Server MTAs that do not recognize the value.
This problem can occur if an MTA does not set the Return-of-Content-Requested bit on the original message. Exchange Server receives the message over the X.400 Connector, converts the P22 content to MDBEF, and delivers the content (or does not deliver it). The Exchange Server MTA then generates the report and does not add the content, but does set the content type to MDBEF. This problem does not normally occur between Exchange Server MTAs because Exchange Server MTAs always set the Return-of-Content-Requested bit on messages.
