XCON: MTA Queue Blocked by NDR or Delivery Receipts (151785)
The information in this article applies to:
- Microsoft Exchange Server 4.0
- Microsoft Exchange Server 5.0
This article was previously published under Q151785 SYMPTOMS
An Exchange Server site that backbones over a foreign X.400 system to
another Exchange Server site develops a message backlog for mail destined
for the remote Exchange Server site. This message backlog is unrelated to
any network communication problems. The message delivery problem may be
unidirectional; that is, messages are being delivered from the remote site,
but not to the remote site.
CAUSE
If a report message (that is, a non-delivery report [NDR], or a delivery
receipt) is returned from the remote site and the foreign X.400 system used
as a backbone adds unanticipated encoding for the property Report-
Additional-Info, the message may block the MTA queue.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
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
