While I think X.400 was a design by committee it surely made sense to 
the committee :-)-O. 

At the time :-)-O

I remember talking to senior staff at the computer center of the
Technical University Aachen (RWTH) where I studied medicine in the 80's
and was playing with BITNET and its connections to other networks (there
was no Internet in Germany yet).

The guy was convinced that X.400 was the way of the future, and I seem 
to recall that this was related to the RWTH being involved with the DFN 
(German Research Network).

Given that we have QR codes and address books, the hyperventilating
about X.400 addresses is amusing :-)-O. If events had not taken over we
would all be used to nice interfaces of mail programs where one could
enter the elements in a nice way to be available for easy use.

And while

is of course preferable to


not only for unwieldiness, but also for provider independence (DNS), I
am most unsure how store and forward would have scaled to current
volumes :-)-O
