Following are the response to my original posting requesting information
on UNIX and DOS implementations of an X.400 product. I did not recieve
very much which was useful except for the original posting response from
Tim Kehres. Enjoy ...

UNIX:
I don't know of any existing public domain versions yet, but there is
a rumor that S. Kille (UCL), is working on a version. I don't know
if there is any truth to this or not.
We are looking into some combination of purchasing/developing a
commercial version of X.400 with directory services. My feeling
at this time is to do most of the development rather than pay the
incredibly high rates for source code that the only viable vendor
(currently) is charging. If you are interested in any of the stuff
we are looking into, please let me know.
Sydney Development Corporation has the only working commercial version
at this time. The word that I heard at the MHS meeting in Munich last
month however was that their implementation had some serious bugs. I
don't have details on this yet however. You can contact them at
(604) 734-8822 or (800) 663-6951.
Retix claims to have a version, but I am told that they will not
adapt to anything other than the strict ISO model. This makes working
with other lower layers like TCP/IP (and I assume the IBM stuff also)
either not practical or difficult. They can be contacted at
(213) 829-4922.
All other versions that I know of will not port to the UNIX
environment.
DOS:
It is generally believed that DOS machines do not have the capability
for a full X.400 implementation. You might want to talk to Sydney
however, since I believe that they have something for this market.
You might want to look into the new P7 protocol for PC<-->MTA
communication (a generalization) to see if this makes any sense.
All versions that I know of are based on the 1984 series of recommendations.
It is unclear as to what will happen when the 1988 compatible systems start
to appear. You might want to make sure that directory services are included
with any X.400 product that you receive. Even though the details of this are
not worked out yet, whatever vendor you go with should be planning their X.400
offering with this in mind.

There was a recent description of an implementation in an interview in
UNIX Review. As with all things designed by committee this bohemoth was
1.5 Megawords and the supporter of X.400 that was being interviewed
called it "the ADA of mailing systems".
