Abstract

This document describes a set of mappings which will enable inter working between systems operating the CCITT X.400 ( 1984 / 1988 ) Recommendations on Message Handling Systems, and systems running the Mail-11 (also known as DECnet mail) protocol. The specifications are valid within DECnet Phase IV addressing and routing scheme.

Abstract

This document describes a set of mappings which will enable inter

working between systems operating the CCITT X.400 ( 1984 / 1988 )

Recommendations on Message Handling Systems, and systems running the

Mail-11 (also known as DECnet mail) protocol. The specifications are

valid within DECnet Phase IV addressing and routing scheme.

The complete scenario of X.400 / RFC822 / Mail-11 is also considered,

in order to cover the possible complex cases arising in multiple

gateway translations.

This document covers mainly the O/R address to DECnet from/to address

mapping (and vice versa); other mappings are based on RFC 1327 and

its eventual future updates.

This is a combined effort of COSINE S2.2, the RARE MSG Working Group,

and the IETF X.400 Ops Working Group.

Chapter 1 - Introduction

1.1. X.400

The standard referred shortly into this document as "X.400" relates

to the CCITT 1984 and 1988 X.400 Series Recommendations covering the

Message Oriented Text Interchange Service (MOTIS). This document

covers the Inter Personal Messaging System (IPMS) only.

1.2. Mail-11

Mail-11, also known as DECnet mail and often improperly referred as

VMSmail, is the proprietary protocol implemented by Digital Equipment

Corporation (DEC) to establish a real-time text messaging system

among systems implementing the DECnet Phase IV networking protocols.

1.3. RFC822

RFC822 was defined as a standard for personal messaging systems

within the DARPA Internet and is now diffused on top of many

different message transfer protocols, like SMTP, UUCP, BITNET, JNT

Grey Book, CSnet. Its mapping with X.400 is fully described in

RFC1327. In this document we will try to consider its relations with

Mail-11, too.

1.4. The user community

The community using X.400 messaging system is currently growing in

the whole world, but there is still a number of very large

communities using Mail-11 based messaging systems willing to

communicate easily with X.400 based Message Handling Systems. Among

these large DECnet based networks we can include the High Energy

Physics network (HEPnet) and the Space Physics Analysis Network

(SPAN).

These DECnet communities will in the future possibly migrate to

DECnet Phase V (DECnet-OSI) protocols, converting thus their

messaging systems to OSI specifications, i.e., merging into the X.400

MHS...
