Even so, split DNS still doesn't necessarily help a solitary firewall
relay. Teh relay needs to see the external view for outbound mail and
the internal view for inbound. Tricky when the DNS is defined by a
system-wide config file, namely /etc/resolv.conf. I guess multiple
instances in seperate chroot environments might do it, but that's a
lot of work.
