I'm interested in getting feedback on what common pseudo-domains are
genrally useful in an Internet environment with many different types
of people wanting to mail to all sorts of places that don't yet have
clean domain-style addresses [yes, pseudo-hosts can be useful, too, but
that's another story...].

Here's what I'm using (ruleset zero stuff)...

The most used pseudo-domains I have are for UUCP and BITNET.  Provided
decent relays are defined as $U and $B, that's:


R$*<@$+.bitnet>$*	$#$M $@$B                $:$1<@$2.bitnet>$3
R$*<@$+.uucp>$*		$#$M $@$U                $:$1<@$2.uucp>$3

However, I also find these useful:

R$*<@$*.vnet>		$#$M $@ibm.com           $:$1<@2>$3
R$*<@$+.hepnet>$*	$#$M $@lbl.gov           $:$1<@$2.hepnet>$3
R$*<@$+.janet>$*	$#$M $@nss.cs.ucl.ac.uk  $:$1<@$2.janet>$3
R$*<@$+.mfenet>$*	$#$M $@lbl.gov           $:$1<@$2.mfenet>$3
R$*<@$+.sdscnet>$*	$#$M $@sds.sdsc.edu      $:$1<@$2.sdscnet>$3
R$*<@$+.xerox>$*	$#$M $@xerox.com         $:$1.registry

And I'm retaining this pseudo-domain as a crutch for people who still
insist upon mailing to user@mumble.csnet instead of
user@mumble.cs.net

R$*<@$+.csnet>$*	$#$M $@$2.cs.net         $:$1<@$2.cs.net>$3

And this for people who want to type user@mumble.span instead of
user@mumble.span.nasa.gov

R$*<@$+.span>$*		$#$M $@$2.span.nasa.gov  $:$1<@$2.span.nasa.gov>$3

I've not yet figured out a general and reliable way to route mail using
a .fido pseudo-domain.

The .acsnet pseudo-domain seems to be obsolete (and, of course there are
other .au addresses, but I believe those are handled correctly with MXs):

#R$*<@$*.ACSNET>         $#$M $@$2.oz.au          $:$1

And so, I think are these, since apparently domain-style addresses (and MX
records) exist.  True?

#R$*<@$+.CDN>$*		$#$M $@relay.cs.net      $:$1%$2.CDN<@ucb.csnet>$3
#R$*<@$+.COSAC>$*	$#$M $@relay.cs.net      $:$2/$1<@france.csnet>$3
#R$*<@$+.DFN>$*		$#$M $@relay.cs.net      $:$1%$2.DFN<@ucb.csnet>$3
#R$*<@$+.JUNET>$*	$#$M $@relay.cs.net      $:$1%$2.JUNET<@utokyo-relay>$3
