XFOR: Microsoft Mail Recipients Do Not Receive NDRs If CRs Exist

• Microsoft Exchange Server, version 5.0

SYMPTOMS

A message sent from a Microsoft Mail user to a Microsoft Exchange Server system via the Microsoft Mail Connector interchange (MSMI) and routed to the Internet Mail Service (IMS) may not be delivered because the destination host is unavailable. If the message remains in the IMS queue until the message timeouts expire, the non-delivery report (NDR) will not be delivered to the originating Microsoft Mail sender. The NDR will reach the shadow postoffice of the MSMI and be renamed with a .max extension.

CAUSE

The SMTP proxy address for the custom recipient is the destination address rather than the Microsoft Mail address.

WORKAROUND

To work around this problem:

• Remove the custom recipient object. If this is not an acceptable option, please see STATUS section below.
