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.
