I'd be more than a bit surprised.  They don't exist.  The Proline sites
aren't on the Internet.

Conveniently, you can send mail since they have MX record through CTS.COM
which happily provides gateway service.

Actually, take a look at your own .sig file.  The .Bitnet address isn't
a *real* address.  It's a signal to intelligent mailers that you want to
get a message to psuvm.  So, if you're on an Internet site, it routes
though a gateway like cunyvm.cuny.edu (there are 4 common ones).  That's
why addresses like psuvm.bitnet don't have an IP address either, even
if they have domain-style names.
 
Obviously, psuvm.psu.edu does have an MX record...

Actually, ALL of cts.com is gateway'd through 'crash' on UUCP.  The MX
record points to trout.nosc.mil (an Internet host that forwards mail to
'crash').

>Obviously, psuvm.psu.edu does have an MX record...

Not so obvious.  psuvm.psu.edu is directly connected to the Internet
(has an 'A' record) -

psuvm.psu.edu      A = 128.118.56.2, 128.118.84.2, 128.118.85.2, 128.118.101.2

It's also PSUVM on BITNET - which means it's its own gateway :-)

Don't ask me why it needs FOUR IP numbers -- I only know what the nameserver
tells me.
