XCON: MTA Mishandles Use of Default Dialogue-mode

ID: Q140958

The information in this article applies to:

Microsoft Exchange Server, version 4.0

SYMPTOMS

Microsoft Exchange Server is unable to communicate with a remote Message Transfer Agent (MTA) over an X.400 connector. In some cases you might be able to send to the foreign MTA, but it cannot receive messages. This is the case with the MEMO MTA.

MORE INFORMATION

The problem only happens when the remote MTA does not explicitly send the dialogue mode in the SPDU Connect packet. This fact can be verified by tracing the beginning of the X.400 connection.

One workaround is to configure both MTAs to the "two way alternate" dialogue mode.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem was corrected in Microsoft Exchange Server 4.0 U.S. Service Pack 2. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
