> How can I send mail to x400 network from internet side

Raimo,

Again: contact your local FUNET person: Marko Kaittola. He will
probably tell you that the address seen from RFC 822 will have different
mapping dependent on the destination country. Ex from Norway and USA:

You can send a message from your Internet Mailbox to the X.400 address

   c=no; admd= ; prmd=uninett; o=sintef; ou=elab-runit; pn=Alf.Hansen;

by typing: Alf.Hansen@elab-runit.sintef.no

.. and you can reach the X.400 address

   c=us; admd= ; prmd=xnren; o=UW-Madison; ou=cs; pn=Alf.Hansen;

by typing: Alf.Hansen@pilot.cs.wisc.edu

Easy, isn't it? The strategy in the R&D MHS Service so far has been to
publish both forms (the X.400 and the RFC 822 form), and to coordinate
internationally the mapping tables everywhere.

There are two alternatives to this solution:

    1) Agree internationally on ONE mapping
       (probably unrealistic)

    2) Use DDAs as described in RFC 987/1148.

If 2),  the above X.400 addresses would look like (seen from Internet Mail
in Finland):

  "c=no;admd= ;prmd=uninett;o=sintef;ou=elab-runit;pn=Alf.Hansen;"@x400gw.fi
and
  "c=us;admd= ;prmd=xnren;o=UW-Madison;ou=cs;pn=Alf.Hansen;"@x400gw.fi

where x400gw.fi is pointing to your local gateway.

RARE WG1 and the R&D MHS Managers are discussing their current strategy
right now in Brussels. This will also be an important issue
at the meeting in the IETF X.400 Operations Working Group meeting in
February.

Best regards,
Alf H.
