The US domain has no gateways. killer.dallas.tx.us is really more of a long
hostname than a domain. We do get the advantages of an Internet MX forwarder
(or five), though.

foo.la.ca.us would send mail to bar.la.ca.us just like foo would send mail to
bar. If both are UUCP hosts, which is likely, than it can be assumed
that pathalias routing will do the trick. Internet sites running decent,
newer mailers will have no problem getting mail to sites in the US domain.
For example, killer's primary MX forwarder is ames.arc.nasa.gov; a good
version of sendmail would find that MX record and send mail for killer
through ames. ames does the rest.
