APPLIES TO


This article was previously published under Q168136

SYMPTOMS

When sending messages using an X.400 Connector from a foreign message transfer agent (MTA) to an Exchange Server MTA with an ADMD= " " (Space), a non-delivery report (NDR) will be generated which refers to invalid parameters.

CAUSE

This problem occurs because of the way Exchange Server MTA handles numeric ADMD (Administrative management domain name).

MORE INFORMATION

Exchange Server supports this properly in all originator/recipient address fields but not in other parts of the envelope (for example, MTSID, Bilateral-Info, External, and Internal-Trace- Info).

WORKAROUND

To work around this issue, do not use a space or numeric name for the Exchange Server MTA when connecting with foreign MTAs.

STATUS

Microsoft has confirmed this to be a bug in Exchange Server 4.0.

This bug was corrected in Exchange Server 5.0.
