Abstract

   This document describes protocol options for conveying objects that

   have been protected using the Cryptographic Message Syntax (CMS) and

   Secure/Multipurpose Internet Mail Extensions (S/MIME) version 3.1

   over an X.400 message transfer system.

1. Introduction

   The techniques described in the Cryptographic Message Syntax [CMS]

   specification and message specifications can reasonably be

   transported via a variety of electronic mail systems.  This

   specification defines the options and values necessary to enable

   interoperable transport of S/MIME messages over an X.400 system.

   This document describes a mechanism for using CMS objects as the

   message content of X.400 messages in a native X.400 environment.

   This means that gateways or other functions that expect to deal with

   IPMS, such as those specified in [MIXER] and [BODYMAP], cannot do

   anything with these messages.  Note that cooperating S/MIME agents

   must support common forms of message content in order to achieve

   interoperability.

   Definition of gateway services to support relay of CMS object between

   X.400 and SMTP environments is beyond the scope of this document.
