Now that we have bsmtp, the answer is simple.  If you want to be
domainist, send mail to all your remote neighbours with bsmtp and
don't prefix myhost! on to the front of the From: header.  Be sure
that you know how to route though!  (Otherwise mail won't get though
when people reply back)

If you want your mail to work rather than be strictly correct according
to the rules, prefix myhost! on the front of mail to your remote neighbours
and send it via rmail.  Mail will go through because it's worked this
way for years.  (Not to mention that you should probably convert @hosts into
leading host.do.main!s just so someone else's mail down the road won't break
it up in an un-replyto-able way...)

Now, to all the hosts (leadsv, for example) that pass mail without adding
myhost! to the front but don't pass mail via bsmtp, tisk tisk -- do you know
how much mail you cause to bounce every day?  And don't tell me that it
isn't so.. Being on the postmaster alias for a backbone site tends to show
one which mail does and doesn't go through.
