A Revised Internet Draft is available from the on-line Internet-Drafts 
directories.                                                               

       Title     : A tutorial on gatewaying between X.400 and Internet mail
       Author(s) : J. Houttuin
       Filename  : draft-houttuin-rfc1327-tutor-04.txt, .ps
       Pages     : 39

There are many ways in which X.400 and Internet (RFC 822) mail systems can 
be interconnected. Addresses and service elements can be mapped onto each 
other in different ways. From the early available gateway implementations, 
one was not necessarily better than any other, but the sole fact that each 
handled the mappings in a different way led to major interworking problems,
especially when a message (or address) crossed more than one gateway. The 
need for one global standard on how to implement X.400 - Internet mail 
gatewaying was satisfied by the Internet Request For Comments 1327, 
"Mapping between X.400(1988)/ISO 10021 and RFC 822."        

This tutorial was produced especially to help new gateway managers find 
their way into the complicated subject of mail gatewaying according to 
RFC 1327. The need for such a tutorial can be illustrated by quoting the 
following discouraging paragraph from RFC 1327, chapter 1: "Warning: the 
remainder of this specification is technically detailed. It will not make 
sense, except in the context of RFC 822 and X.400 (1988). Do not attempt 
to read this document unless you are familiar with these specifications."
