MORE INFORMATION
When an SMTP Host connects to the Microsoft Exchange IMC, there are certain
headers sent by the SMTP Host that the Microsoft Exchange IMC uses to
determine the actions to perform. The headers listed above are the headers
that the Microsoft Exchange IMC understands. If any other headers are
received by the Microsoft Exchange IMC, the message will be accepted and
the unknown headers will be ignored.
To save headers in the Microsoft Windows NT Event Log, start the Microsoft
Exchange Administrator program, open the property page for the Microsoft
Exchange IMC, choose the Diagnostic Logging tab, and set the Logging level
to Maximum.
