I don't know sendmail well, but was wondering could you have a sendmail
setup for both machines that would get the email sent out of the box, i.e.
it would have an alias list for local users that was pointing to the DNS
name of your mail hub, and run a second sendmail process under heartbeat
control which would do all the normal reception from outside of the box,
i.e. as the mail hub?
It would of course mean you would have to maintain two config files as well.
