I won't be leaving this box up perpetually for sure.  I have a 4000-200
with a newer version of MULTINET and VMS that allows a person to send and
receive mail with "normal" email addresses but even that one is only left
running occasionally.  I watch attempts every few minutes to probe it from
the outside world, sheesh, bots.


This is what I use to compare the mVax3100 and my 4000-200.  I could not
find anything other than the versions of the services to explain why one
could not use simpler email addressing (bill at emaildomain.com).

Basically, the 3100 with it's older multinet and VMS "works as designed"
which for now is fine with me.  I just wanted to be sure I did not need to
perform a trick everyone but me knows about to streamline email, other than
simply upgrade these services.

Thanks again for your reply.
