X.400 is the name of a standard put out by CCITT.  Generally when
people say X.400 they mean the X.400 Series of Recommendations|MOTIS.
These are a series of standards documents from CCITT and ISO which
provide store and forward messaging.  The most common usage of this
standard is as a basis for electronic mail.

X.400 is a superset of the functionality available on the internet
and includes usage of non-text messages,  a Directory,  etc.

I believe the standard VMS product is not compliant to X.400 but
rather uses its own,  proprietary,  protocol.
