[comp.protocols.iso.x400.gateway] RFC-987 - 822.msg.id -> P2.IPMessageID mapping

ma@dde.dk (michael andersen) (01/24/91)

We are rigth now working on an RFC-987 gateway, but we do have a
problem with the 822.msg-id -> P2.IPMessageID mapping.

The problem is how to map an 822.msg-id into an OR-Name.

The RFC-987 just says "822.addr-spec is mapped to P2.IPMessageID.ORName
as defined above" but what do we do when our 822.msg-id don't contain a
normal RFC-822 address.

F.ex. how do we map the 822.msg.id below into an P2.IPMessageID ?

Message-Id: <9006121212.AA12456@Kurt.dde.dk>

There were some fundamental problems with the 987 mapping of message IDs.
Have a look at RFC 1148, which fixes this up.

The IP Message Id ends up with an ORName in the DDA form:

   /DD.RFC-822=9006121212.AA12456(a)Kurt.dde.dk/.../

This has been known to cause problems with other implementations,
especially those compare IPMessageIds for equality but don't compare
the DDA fields of the ORNames.
