The UUCP project has decided to use a related syntax:
	domain!user
for this.  Thus, instead of rmail from root@ucbvax.UUCP
(the user level syntax), the transport layer uses
ucbvax.UUCP!root.  Since the local site understands this,
and the local site name will be prepended before the mail
goes out, you get your machine name prepended cbosgd!ucbvax.UUCP!root.

The advantage to this transport syntax is that no hosts that
understand @ or ! will misinterpret it.  The From: line and
the commands the user will type will still be user@domain.
