The information in this article applies to:
- Microsoft Exchange Server, version 4.0 
-------------------------------------------------------------------------------
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.
