Abstract

This memo is the complete technical specification to store in the Internet Domain Name System (DNS) the mapping information (MCGAM) needed by MIXER conformant e-mail gateways and other tools to map RFC822 domain names into X.400 O/R names and vice versa. Mapping information can be managed in a distributed rather than a centralised way. Organizations can publish their MIXER mapping or preferred gateway routing information using just local resources (their local DNS server), avoiding the need for a strong coordination with any centralised organization. MIXER conformant gateways and tools located on Internet hosts can retrieve the mapping information querying the DNS instead of having fixed tables which need to be centrally updated and distributed.

Abstract

This memo is the complete technical specification to store in the

Internet Domain Name System (DNS) the mapping information (MCGAM)

needed by MIXER conformant e-mail gateways and other tools to map

RFC822 domain names into X.400 O/R names and vice versa. Mapping

information can be managed in a distributed rather than a centralised

way. Organizations can publish their MIXER mapping or preferred

gateway routing information using just local resources (their local

DNS server), avoiding the need for a strong coordination with any

centralised organization. MIXER conformant gateways and tools located

on Internet hosts can retrieve the mapping information querying the

DNS instead of having fixed tables which need to be centrally updated

and distributed.

This memo obsoletes RFC1664. It includes the changes introduced by

MIXER specification with respect to RFC1327: the new 'gate1' (O/R

addresses to domain) table is fully supported. Full backward

compatibility with RFC1664 specification is mantained, too.

RFC1664 was a joint effort of IETF X400 operation working group

(x400ops) and TERENA (formely named "RARE") Mail and Messaging

working group (WG-MSG). This update was performed by the IETF MIXER

working group.

1. Introduction

The connectivity between the Internet SMTP mail and other mail

services, including the Internet X.400 mail and the commercial X.400

service providers, is assured by the Mail eXchanger (MX) record

information distributed via the Internet Domain Name System (DNS). A

number of documents then specify in details how to convert or encode

addresses from/to RFC822 style to the other mail system syntax.

However, only conversion methods provide, via some algorithm or a set

of mapping rules, a smooth translation, resulting in addresses

indistinguisha...
