For one thing, why would your have a bunch of uucp machines that only know
! addresses (which are probably actually routes, NOT addresses)? With
the free smail package, and the ease with which it can be installed, there
just doesn't seem to be a reason why a uucp machine can not understand
the "@" syntax.

One clarification:

   ...!uunet!epimass.epi.com!jbuck is NOT an address, it is a route. Using
this type of syntax depends on where you are sending the mail from. For one
person, the route might be ihnp4!rutgers!uunet!epimass.epi.com!jbuck, and
for someone else, it might be ucbvax!harvard!uunet!epimess.epi.com!jbuck.
It's not an address if it depends on where the mail is being sent from.


   An address would be:

	jbuck@epimass.epi.com
		or
	epimass.epi.com!jbuck

provided your are running smart mailer. This address will get mail to Joe
no matter where it is being sent from, including UUCP machines running 
smart mailers, and the DDN.

Mark Horton gave a good example somewhere, which I forget, that gives a good
example of the difference between a route and an address. If you think of
an address in the sense of a postal address, it makes sense: No matter where
you mail a letter from, the address for the recipient always stays the same,
regardless of if you're in New York, California, or even (God forbid!)
Columbus, Ohio.
