The usage of the X.400 Message Handling System (MHS) is growing rapidly, especially in the commercial world but much interest can also be found in the academic and research community. New networks and new addresses come into use each and every day. The underlying technology for different X.400 networks can vary depending on the transport network and the X.400 MHS implementations used. As a large number of X.400 implementations now support multiple stacks, this offers the chance of implementing a world wide message handling service using the same electronic mail standard and, therefore, without the need of gateways with service reduction and without the restriction to a single common transport network. This, however, leads to several problems for the MHS manager, two of which are:
- Where do I route new X.400 addresses and
- How do I connect to a MHS domain that uses an underlying technology that I do not support.
This document proposes short term solutions to these problems. It proposes a strategy for maintaining and distributing routing information and shows how messages can travel over different networks by using multi stack MTAs as relays. Document formats and coordination procedures bridge the gap until an X.500 directory service is ready to store the needed connectivity and routing information. The format has been designed to allow the information to be stored in an X.500 directory service while managers without directory service access may still use a table based approach.
The routing structure proposed can be applied to a global MHS service

Many experts from IETF X.400-Operations Group and RARE Working Group 1 on Message Handling Systems have read drafts of this document and contributed ideas and solutions. I would especially like to thank Harald Alvestrand, Erik Huizer, Marko Kaittola, Allan Cargille and Paul-Andre Pays.
This is the third version of a table format. The first one was in use within COSINE-MHS for about two years. A second version with major enhancements was then proposed which has been in use for the past year. The third version will probably be the last one before it will be possible to switch to dynamic, directory service based routing.
