   The headers on the following message display a nightmarish combination
   of domain-style host names and routing-style recipient addresses.
   I cannot help making this observation.  A previous message
   referred to confusion between RHEA.DEC and RHEA.ARPA (RICE-RHEA).
   What gives the domain "DEC" legitimacy?

I don't see any problem with the above header.  The "DEC" is part of
the local address (not the domain). The UUCP-address and ENET-address
fields are user comments since they are not defined in RFC-822.
What the problem?

Assuming the gateway from DEC to ARPA mail domain puts the DEC address
in the Internet local address and adds a valid Internet domain name
to the right of the "@" there is no problem for the Internet mail world.
