You're mixing apples and turnips. X.400 is the family of ISO standards
for email and didn't have anything to do with DECnet. The Mail-11
protocol might loosely be considered a DECnet application level protocol
for email.
Right. I suspect Rich was actually thinking of the 7 layer OSI model,
which DEC tried really hard to implement.
(And no, TCP/IP do *not* follow the 7 layer OSI model.)
Oh, and the 7 layer OSI model is also called X.200.
