   I've recently been trying to learn what I can about X.400.  Technical
information on the subject ( though not overly abundant ) is available.
For example, I have CCITT Red Book Volume 8 Fascicle 8.7 and RFC 987 which
describes the mapping between X.400 and RFC 822.  However, I haven't been 
able to find out what the state of its use in the real world is.  If 
anyone on the net can help me answer the following questions I would be 
very appreciative ( please send e-mail ):

1) Which major corporations have messaging systems that can talk X.400?
   ( I understand that DEC's All-In-1 does. )

2) Does anyone OEM a complete implementation of the Messaging Handling
   System?

3) For those of you in a position to speculate, how widespread do you see 
   the acceptance/implementation of X.400 being?  Will it eventually
   overtake SMTP as the mail handling protocol of choice on UNIX systems?
   Is corporate USA clamoring for it, thinking about it, or oblivious of it?

Disclaimer: The information that I am seeking is for personal edification
            only.  My employer who graciously provides my connection to this
            forum has nothing to do with this posting.
