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.
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.
