Chapter 1 -- Overview

1.1.  X.400

   This document relates primarily to the ITU-T 1988 and 1992 X.400
   Series Recommendations / ISO IEC 10021 International Standard.  This
   ISO/ITU-T standard is referred to in this document as "X.400", which
   is a convenient shorthand.  Any reference to the 1984 Recommendations
   will be explicit.  Any mappings relating to elements which are in the
   1992 version and not in the 1988 version will be noted explicitly.
   X.400 defines an Interpersonal Messaging System (IPMS), making use of
   a store and forward Message Transfer System.  This document relates
   to the IPMS, and not to wider application of X.400, such as EDI as
   defined in X.435.

1.2.  RFC 822 and MIME

   RFC 822 evolved as a messaging standard on the DARPA (the US Defense
   Advanced Research Projects Agency) Internet.  RFC 822 specifies an
   end to end message format, consisting of a header and an unstructured
   text body.  MIME (Multipurpose Internet Mail Extensions) specifies a
   structured message body format for use with RFC 822.  The term "RFC
   822" is used in this document to refer to the combination of MIME and
   RFC 822. RFC 822 and MIME are used in conjunction with a number of
   different message transfer protocol environments.  The core of the
   MIXER specification is designed to work with any supporting message
   transfer protocol.
