XCON: Read Receipt May Not Be Returned From ISOCOR MTA (170054)
The information in this article applies to:

- Microsoft Exchange Server 5.5
This article was previously published under Q170054 SYMPTOMS
When a Microsoft Exchange user sends a message with a read receipt request
to an ISOCOR message transfer agent (MTA) user, the ISOCOR MTA may not send
back a read notification report.
CAUSE
This behavior can occur when the Microsoft Exchange user sends the message
to an ISOCOR user with the following X.400 address:
C=us;A-md;P=prmd;O=organization;S=surname;CN=common-name
When the CN address field is used over a 1984 mode X.400 connection, it is
moved to the Domain Defined Attribute (DDA) field during the downgrade
process. If the message also contains a delivery receipt request, the
ISOCOR MTA sends that, but does not send back a read notification report.
This has been found to be a limitation in the ISOCOR ISOPLEX 800 v.1.15.
This behavior is by product design.
