I don't remember the details of what email addresses looked like in the days when DEC was first connected to the Internet (or ARPAnet).  There was a bunch of magic at the WRL gateway (gatekeeper.dec.com -- also one of the first firewalls).  A lot of this can be done by suitable magic in sendmail.cf.  At some later time I believe that the mapping from SMTP addresses to DECmail addresses was pretty much transparent, so you could indeed send that simple address  you mentioned.  Earlier on it was something like "ark::[1,211]"@decwrl.dec.com or perhaps kremvax!decwrl!ark!1,211 ...
