You address mail to a Microsoft Exchange 4.0 Internet Mail Connector (IMC)
recipient or a Microsoft Exchange 5.0 Internet Mail Service (IMS) recipient
and the message arrives at the destination with the "From:" and "To:"
fields encapsulated in an X.400 address.
↑ Back to the top
Your message is travelling over an X.400 connector before going through the
IMC or IMS.
Once a message reaches a site and the site does not recognize the
originator of the message, the Exchange server will encapsulate the message
in the type of address format that got it to the site in the first place,
in this case, X.400.

To work around this problem and keep this encapsulation fom happening, the
Microsoft Exchange Site must be aware of all originators and recipients
that
it handles mail for. You must either configure a Directory Replication
connector or Import the addresses as Custom Recipients. This will allow the
Exchange server to recognize the Originator and Recipients of a message and
not encapsulate it.
