        RFC 1496:

        Title:      Rules for downgrading messages from X.400/88 to
                    X.400/84 when MIME content-types are present in
                    the messages

Interworking between X.400(88) and X.400 (84) is achieved by RFC 1328.
That document does not describe what to do in the case where body
parts arrive at the gateway that cannot be adequately represented in
the X.400(84) system.  This document describes how RFC 1328 must be
modified in order to provide adequate support for the scenarios:
SMTP(MIME) -> X.400(84), and X.400(84) -> SMTP(MIME).

This is now a Proposed Standard Protocol.

This RFC specifies an IAB standards track protocol for the Internet
