XCON: X.400 Backbone Must Route SMTP Messages By DDA Type (182952)
The information in this article applies to:
- Microsoft Exchange Server 5.0
This article was previously published under Q182952 SUMMARY
To send Simple Mail Transfer Protocol (SMTP) messages over an X.400
backbone using Microsoft Exchange Server, the backbone systems must be
configured to route messages based on the Domain Defined Attributes (DDA)
type in the originator/recipient (O/R) address of the messages. If one or
more backbone systems are unable to route messages based on the DDA type,
you cannot send SMTP messages over the backbone.
MORE INFORMATION
Microsoft recognizes the need for Exchange Server to allow SMTP messages to
be sent over an X.400 backbone that cannot route messages based on the DDA
type. We have modified the Microsoft Exchange Server 5.0 message transfer
agent (MTA) so that SMTP messages can be routed to a dedicated X.400
private management domain (PRMD) that contains an Internet Mail Service or
other Internet connection. This feature allows Exchange Server to convert
SMTP one-off addresses to X.400 one-off addresses, based on information in
the X.400 connection to the system used to connect to the Internet.
This supported feature is now available, but has not been fully regression
tested and should be applied only to systems having a specific need for it.
Unless you are severely impacted by the lack of this feature, Microsoft
recommends that you wait for the next Service Pack that contains this
feature. Contact Microsoft Technical Support for more information.
