I'm about to set up mailing in one of our sub-domains. What I want to end
with is the following:

Mail should be adressed to <user>@<domain>, instead of <user>@<host>.

An example:

User 'joe' works at machine 'ws1.edvz.univie.ac.at'. However this fact
should be hidden from the outside world; i.e. somewone should be able to
address mail to "joe@edvz.univie.ac.at" or even "joe@univie.ac.at".
Naturally mail should finally arrive at 'joe' on his machine
'ws1.edvz.univie.ac.at". When joe replies to the mail it should appear to
the recipient as if it came from "joe@edvz.univie.ac.at" not
"joe@ws1.edvz.univie.ac.at".

I've seen numerous examples of such mail-addresses in the past. Does
anybody out there have an idea how to get that working?  Are modifications
necessary in the nameserver (MX-records)? Or should changes be done to the
senmail-config?

This all should work under SunOS 4.1.1.

Thanks in advance for any help,
