Yay??

That is a strange config for Exim (to me, because I never tested that
before.

From your explanation, you are saying, for example if we take two
interfaces on that server, you want Exim to listen on each of them,
but on different ports, so:

local_interfaces = <, a.b.c.d.25 , w.x.y.z.26

well, if you want it. If no local_interfaces directive is given to Exim
(and to most other daemons) it ends up binding to all available ones,
including the loopback interface.

Which is why you shouldn't be doing anything this complicated, but I
am not underestimating your capabilities!

Why don't you let Exim listen on the default port 25 and Lyris to use
port 26? I believe there is no hard-coded port in Lyris, no? I have
never seen it even.

See spec.txt and even the FAQ, on notes regarding starting Exim on a
non-standard port. There have been some changes in this area lately (IIRC)
but you normally needed to start exim with "-oX port_number" ...
Take a good look at the ChangeLog/NewStuff documents of the Exim version
you are running!

Lastly, if I may ask (at the risk of going OT) why do you prefer Lyris
over Mailman?
