XCON: NDR "Invalid Parameters" (168140)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q168140 SYMPTOMS
When a message originates from a third-party message transfer agent (MTA)
by way of an X.400 connection to the Microsoft Exchange MTA with an
administrative management domain (ADMD) that is a space, a non-delivery
report (NDR) is generated with the message text "invalid parameters."
CAUSE
This happens because the MTA improperly handles a numeric ADMD. Many
third-party MTAs generate a numeric character 0 for a space rather then an
alphanumeric null. Microsoft Exchange Server properly supports this in all
O/R address fields but not in other parts of the message envelope (for
example, MTSID, Bilateral-Info, External and Internal-Trace-Info).
The Microsoft Exchange Server 4.0 MTA does not properly handle the
numeric ADMDs; however, the Microsoft Exchange Server 5.0 MTA is able to
properly distinguish between numeric and alphanumeric ADMD fields.
WORKAROUND
To work around this issue, do one of the following:
- Change the third-party ADMD to something other than a space.
-Or- - Upgrade to Microsoft Exchange Server 5.0.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange version
4.0. This problem has been corrected in the latest U.S. Service Pack for
Microsoft Exchange Server version 4.0. For information on obtaining the
Service Pack, query on the following word in the Microsoft Knowledge Base
