As always, there's an exception to the rules ;) You can cheat if the
server is NEVER going to receive mail and implement 521 reply codes
(
http://www.faqs.org/rfcs/rfc1846.html). This type of host simply never
recieves mail and is exempt from receiving postmaster mail. You would
stil have to avoid putting the hostname in a reply-to email since it's
never meant to be a source of mail.
