XADM: Delivery Receipt Has Unknown for To, Subject, and Sent
ID: Q147545
|
The information in this article applies to:
-
Microsoft Exchange Server, version 4.0
SYMPTOMS
When you send a message from a Microsoft Exchange Server site over the X.400
Connector, the delivery receipts are incomplete. It contains the following:
Your message
To: Unknown
Subject: Unknown
Sent: Unknown
was delivered to the following recipient(s):
/o=MICROSOFT/ou=EXCHNGSITE/cn=Recipients/cn=Admin on 1/18/96 3:59:54 PM
CAUSE
This problem occurs if any of the following conditions are met:
- The X.400 Connector is set to operate in 1984 conformance mode.
- The client has a personal folder store as the default delivery location.
- You have clicked to clear the Save a copy of the item in the 'Sent Items' folder check box
and sent a message.
The X.400 specification generates reports (delivery and read) based on the
information in the message envelope. The envelope does not contain the To,
Subject, and Sent information in the delivery report. Therefore, this
information is not returned by the X.400 system receiving the message.
RESOLUTION
To overcome this limitation of the X.400 specification, Exchange Server
uses the Content Correlator attribute. When a message is sent over the
Exchange Server X.400 connector, an attribute called the Content
Correlator is filled in the envelope of a message. When the X.400 system at
the other end of the X.400 Connector generates a report (delivery or read),
based on the 1988 X.400 specification, the Content Correlator attribute is
returned to the originating system.
MORE INFORMATION
The information store uses the Content Correlator to scan
for a copy of the message in the Sent Items folder. If a copy is found, the
information store extracts the To, Subject, and Sent information and
adds it to the delivery report. If a copy is not found, "Unknown" is entered
for the To, Subject, and Sent fields.
The information store only searches the Sent Items folder in the server-based information store. Personal folder stores are not searched. Therefore, if the
user has the personal folder store set as the default delivery location, "Unknown" is
entered for the To, Subject, and Sent field in the delivery receipts from
the X.400 Connector.
The 1988 X.400 specification guarantees that the Content Correlator
attribute in the envelope is returned to the sender. However, the 1984
X.400 specification does not guarantee this. Therefore, some 1984 compliant
X.400 MTAs may not return the Content Correlator attribute in delivery
reports. As a result, the information store on the sending side enters
"Unknown" for the To, Subject, and Sent fields.
