1.  Introduction

   There are several large, operational X.400 services currently
   deployed. Many of the organizations in these services are connected
   to the Internet.  A number of other Internet-connected organizations
   are beginning to operate internal X.400 services (for example, U.S.
   government organizations following U.S. GOSIP).  The motivation for
   this document is to foster a Global Open Message Handling System
   (GO-MHS) Community that has full interoperability with the existing
   E-mail service based on RFC-822 (STD-11).

   The goal of this document is to unite regionally operated X.400
   services on the various continents into one GO-MHS Community (as seen
   from an end-user's point of view).  Examples of such regional
   services are the COSINE MHS Service in Europe and the XNREN service
   in the U.S.

   A successful GO-MHS Community is dependent on decisions at both the
   national and international level. National X.400 service providers
   are responsible for the implementation of the minimum requirements
   defined in this document. In addition to these minimum requirements,
   national requirements may be defined by each national service
   provider.

   This document refers to other documents which are published as RFCs.
   These documents are [1], [2], [3], [4], [6] and [7] in the reference
   list.

   This document handles issues concerning X.400 1984 and X.400 1988 to
   1984 downgrading. Issues concerning pure X.400 1988 are left for
   further study.
