Pre-standards work for X.400 began in 1978, through IFIP Working Group
6.5.  That's where the UA/MTA conceptual split was developed, based on
the design of 4 existing systems.

The CCITT X.MHS effort (X.400) started in 1980, with the first
publication in 1984.  It was notable for high ambitious and complexity,
but insufficient functionality to be directly useful.  It was also
notable for an addressing scheme that required specifying who your
'carrier' was (ADMD).  Business cards with X.400 addresses, for folk at
large companies, would show a list of several different ADMD operators.

Not sure what this means.  Quite a number of folk involved with the
specification of X.400 had quite a bit of email-related experience.
