Just have two different NIC's to two different non-routable
LAN's; one is your private LAN, the other is for you public
services. Port redirect services into the public net
and firewall it so nothing can connect back out from it.
Then even if your MTA is hacked, all you've lost is the
machine on the public LAN. Your fw and private Lan are
still secure.
