Hello,

We have a set of servers that are load balanced that we need to add an
additional submission port to. The network config is pretty complex and
we end up with two IP's that the new submission port needs to listen to.
Both of these are internal ranges.

Currently we are doing:

10.0.8.80:10027 inet ...
And
10.0.212.24:10027 inet ...

I know this is trivial, as there are many ways to solve this problem
(namely firewalling) but this machine also has external addresses so
they don't want to use 0.0.0.0. Is there a way to configure this so two
separate distrinct smtpd agent aren't created?

The other question, what's the resource impact of running multiple
smtpd's? If it's minimal, then it's a mood point. But I don't know the
answer, thus the question above.
