We operate an e-mail gateway that relays mail between
Mail-11 (DECnet) and SMTP (among others.)  (Our gateway
runs PMDF on a VMS platorm.) 

Let's say that our gateway has a DECnet nodename of
GATE and an Internet domain name of Gate.Arizona.EDU.
When a mail message is sent via Mail-11 thru our gateway 
to an SMTP destination, we rewrite its From: address
as USER%Host.DECnet@Gate.Arizona.EDU.  For example, if Mail-11
user BUGS::LEONARD uses our gateway to send mail to
SMTP user <jones@frobbitz.com>, he'll address his message
to
  GATE::IN%"jones@frobbitz.com"
The SMTP user will receive this message with a From: address of
  LEONARD%BUGS.DECnet@Gate.Arizona.EDU

This approach works well.

Today RFC-1405, "Mapping between X.400(1984/1988) and Mail-11
(DECnet mail)" was published.  In section A3.2, "Mail-11 mapped in
RFC822", this RFC recommends that Mail-11 => SMTP gatewayed
addresses be rewritten as
  "Mail-11-address"@gateway-address

So that, in my example above, jones@frobbitz.com would have received
the message from
  "BUGS::LEONARD"@Gate.Arizona.EDU

Would anyone care to comment on the desireability, or lack thereof,
of changing our rewrite rule to comply with this aspect of RFC-1405?
