Hmm, they may well be unusable for you to return mail (and for
us for all I know :-}) but this form of addressing is the ONLY
way a site with a brain-damaged mailer (eg reading.am.uts - UTS
1.0 (NOT the sys5 clone)) can pass mail to (eg) the ARPAnet. We
simply forward the request to mail to the ARPAnet to some smart
guy who knows whats going on and let them figure it out. So to
mail to user@tove.ARPA, we send to ...smartguy!tove.ARPA!user
and let smartguy figure it out. Surprisingly, it works very
well. Fortunately, we receive ARPA mail by a recognised gateway
to the UK JANET system (ie our primary network is JANET,
though we do UUCP stuff and get USENET news etc).

Before the flames pour in, let me add that this is not given as
our return address (which is in domain format) and does not
munge the header apart from the obvious To line.

I believe this is to do with subdomains, etc.
My official UUCP address is, I believe,
...!reading!cs.reading.UUCP!west (ie west@cs.reading.UUCP).

As well as the usual disclaimers, may I add that I am not
concerned with running this system, and am, therefore, talking
thru my xxx.
