If you can discriminate by incoming IP address you can direct traffic to a
different
machine/port combination (all customers come in over local dial-up vs.
incoming email
from net coming in from a different address range). Even so you would have
to be able
to support both in & out on both machines for those who didn't fit the
above model.
It's hard to think of all eventualities when you build services, but since
A records and
CNAMEs are free you might as well dream up as many as you want.
(You could achieve a similar effect as above by having split-horizon dns,
might be
easier too).
