Summary: From: host!user isn't correct either.

> 	I am vixie!paul.

According the RFC822 this is would not be from user "paul" on host
"vixie", but rather from user "vixie!paul" on the local host!
For non-local mail, the address in the From: header must be of the
form user@domain (ignoring route-addr's, of course).

paul@vixie.uucp seems the best alternative.  Internet only sites won't grok
"vixie!paul" or "paul@vixie.uucp", but RFC822 compliant UUCP sites will
are much happier with the user@host.uucp form.  Why?  Because mailers
at such sites tend to do one of two things when given a From: line containing
just host!user

   :-)	1) they rewrite it to user@host.uucp
or :-(	2) they tack on their own host/domain name (e.g. host!user@mtv.com)
