- Microsoft Mail Gateway to X.400, version 3.2 
-------------------------------------------------------------------------------

SUMMARY
=======

Version 3.2 of the Microsoft Mail Gateway to X.400 supports X.25 the Eicon
interface card for point to point communications on Transport Protocol class 0
(TP0). When you address another X.400 Message Transfer Agent (MTA) on a Public
X.25 Mail Service, you define a remote MTA with a single X.121 address---the
Public Mail Services. The distribution of the message is then routed to the
destination X.121 address, based on the Private Domain Name (PRMD).

MORE INFORMATION
================

Sprint Mail is an example of a public X.25 Mail Service provider that routes on
PRMD. For this reason, it is mandatory that users include the PRMD attribute of
an X.400 address. A correct routing table will ensure proper message routing to
Sprint Mail.

Here is a example of a typical outbound Sprint Mail address and corresponding
routing table:

Recipient Address:
------------------

  C=US; A=TELEMAIL; P=MICROSOFT; O=PSS; OU1=WGA; S=USERMBX

Local Route table:
------------------

  C=US
  .. A=TELEMAIL
  ....O=LOCAL <LOCAL-MTA>
  ....O=* <SPRINT-MTA>

In this example, only one X.121 address was defined for SPRINT-MTA, but by
specifying the Private Domain Name (PRMD) Microsoft, it allowed Sprint to route
the message to the proper X.121 address and receiving MTA.
