SYMPTOMS

If an MS-DOS Microsoft Mail client receives SMTP mail through the Microsoft Exchange Internet Mail Connector (IMC) to a Microsoft Mail Postoffice, the recipient will not see the SMTP headers.

CAUSE

The Microsoft Exchange Microsoft Mail Interchange (MSMI) stores the SMTP headers in the Transport Neutral Encapsulation Format (TNEF) part of the message when it pulls the message from Microsoft Exchange Server and creates a Microsoft Mail file for it. The MS-DOS Microsoft Mail client will not interpret any of the TNEF data, unlike the Window 16 and Windows 32 clients.

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.
