Is this *outgoing* mail you're talking about? The way to do that is
to use control/smtproutes on each of the three servers to send
*everything* remote to the gateway server. If you really want to make
one system that mission-critical. Oops, on *two* of the servers; the
third server actually *is* the gateway so it has to be allowed to
actually send the mail out.

For the inbound mail to come in direct to the right server the simple
way, you need an MX pointing to the system you want the mail to end up
on, and you need to allow direct connects from outside to that system.
If you want to run all inbound email through your gateway instead, you
need to have all the MX records pointing at the gateway, and then use
either control/smtproutes (qmail control file) or else split DNS
(internal systems see different DNS answers than external systems) to
cause incoming mail to go from the gateway to the intended server.
