XCON: MTA: Invalid Originator Address When Sending to X.400

ID: Q146032

The information in this article applies to:

Microsoft Exchange Server, version 5.0

SYMPTOMS

When you send a message from Microsoft Mail through Microsoft Exchange Server 5.0 to someone on an X.400 messaging system, a reply to this message may not be possible. This occurs if you (the Microsoft Mail user) are not a Custom Recipient on Microsoft Exchange Server, which can happen if, for example, directory synchronization is not yet finished.

CAUSE

The message will arrive at the remote X.400 system with an invalid X.400 originator address in the P1 header fields. The X.400 address will only contain a DDA Type and a DDA Value, which contains the Microsoft Mail Address. For example:


   DDA Type=MS;DDA Value=Net/PO/User

This address is invalid because mandatory parts are missing. A valid address would look like this:


   C=Country;A=Admin;P=Private;O=Org;DDA Type=MS;DDA Value=Net/PO/User

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem was corrected in the latest Microsoft Exchange 5.0 Server U.S. Service Pack.
