So MX can do the subdomain -> decnet node name conversion? 

Why not?   Use its rewrite rules.

Assume there is a HECnet.net domain and that all nodenames are used as
hostnames in a FQDN.   The mail handler node is called PMASTR or TCP/IP
hame of postmaster.HECnet.net.

I need to check here but you might even be able to use:

_MCP> "<""{host}::{user}""@localhost>"

...but this might hork up replies.   For more elaborate schemes, MX is
capable of rewriting using *IX-style regular expressions with /REGEX
on the 'DEFINE REWRITE_RULE' command.

For the reverse (outgoing and replies), configure the DN_SMTP server
which is SMTP over DECnet.

MX has alias translation, mailing list features and other delivery
agents such as X25, UUCP and a SITE interface.   The latter allows a
customizable interface to other applications running on its host.   I
once used it to interface to a trouble report (user support) system
and I use it today to provide customers with access to a temporary
licence (PAK) generator for software trials.

In addition, I know the MX developers quite well. ;)
