There is also an end-user orientated User Guide for X.400 -> RFC822 (Internet)
addressing. Parts of the guide also double up for RFC822 -> X.400. Hopefully 
the guide is more readable for users than RFC1327 although RFC1327 is the
bible......the guide is in English & French for the moment. German on the way.
Details on how to get an electronic copy from the COSINE MHS server follow:

'...

This directory holds end user orientated user guides. Included are user guides
in english and other languages that the project team and other contributors
have generated. This information should be made as widely available to end
users as possible.

The addressing-<language>-<version> files details follow:
- the english version is the original and is generated by the project team
- the french version is translated courtesy of the French MHS Service ie. RED
  and in particular by Odile Germes. Many thanks.

To receive particular documents, send the message:
          send public/user-guides <document1> <document2>..

Example:  send public/user-guides addressing-english-060992.txt

Send this message to:
       cosine-mhs-server@nic.switch.ch
or in X.400 format to:
       C=CH;ADMD=arcom;PRMD=SWITCH;O=SWITCH;OU=nic;S=cosine-mhs-server;

Some more details on address conversion services follow. Please note that
the French, German & Dutch services are in the native language and NOT
in English. The Swiss & UK services are in English....

**Conversion Services*
---------------------

The following countries have interactive address conversion services:

Germany
The Netherlands
Switzerland
United Kingdom

In the following countries there is an e-mail responder which does
address conversion:

France
Germany

To access the German conversion service,via terminals use one of the
following addresses:
        Internet (telnet):      sirius.dfn.de
        IP (telnet):            192.76.176.5
        Public X.25 (pad):      26245050335006
Log in to the account named 'adressen', no password, only CR. You'll get
the prompting of the conversion program with help information.

To access the German conversion service via e-mail, send a message
containing the address(es) to be converted in the body to
C=DE; ADMD=DBP; PRMD=dfn; S=adrserv; OR adrserv@dfn.dbp.de
Please write one address per line into the body part of the message. You
will receive a reply containing the converted address(es).

To access the French conversion service, send a message containing the
address to be converted in the body to
C=FR; ADMD=atlas; PRMD=cicb; S=is; OR is@cicb.fr
You will receive a reply containing the converted address.

To access the Dutch conversion service,via terminals use one of the
following addresses (No login is required):
        Internet (telnet):      relay.surfnet.nl 4545
        IP (telnet):            130.161.180.100 4545
        Public X.25 (pad):      20412911004545

To access the Swiss conversion service, use one of the following
addresses:
        Internet(telnet):       nic.switch.ch
        Public X.25(pad):       22847971014540
        IXI(pad):               20432840100540
Log in to the account named 'mailaddr'. Then enter the address you would
like converted.

To access the British conversion service, ORAC, use one of the following
addresses:
        JANET(pad):             00004001025003
        Public X.25(pad):       23421920014813
        IXI(pad):               20433450400213
No login is required. The service converts between grey-book (JANET) mail
or RFC-822 mail,and X.400 addresses, and vice-versa. Calls from JANET
will automatically assume 'uk...' ordering, whilst calls from IXI/public
X.25 will assume '...uk' ordering.

Same comment....the user guides mentioned above work well (best) for
coutries with mapping rules (Standard Atributes or Domain Defined Atributes)
AND gateways that actually use them. However it isn't as bad as is implied as 
most (nearly all??) gateways operated by non-commercial parts of the Internet
use RFC1327 and the tables.
