SYMPTOMS
When there is a invalid X.400 address in the To: field of a message, the Microsoft Exchange Message Transfer Agent (MTA) will not deliver the message to any valid X.400 addresses that might also be present in the To: field.



CAUSE
The O/R Address is generated according to the Oneoff Address and the message is submitted to the MTA. The MTA detects an invalid recipient and generates Non-Delivery Receipts (NDRs) for all addresses. This is by product design.
