Actually, there are 8 interfaces. I only need to move Exim to port 26
on one of those. Do I need to specify every interface, or just the one
that I need to move? The documentation for both Exim and Lyris are
pretty clear - if you only have one IP.

Again, it's unclear to me whether the omission of an interface in the
local_interfaces directive means that interface will be ignored or will
be bound on the standard port.

The local_interfaces directive isn't that complicated - if you're only
managing one IP address...

Well, it's the method called out in the Lyris documentation and would
seem simpler from a administration side.

Feature set - it's the only package we've found that has both a web and
mail interface without having database synch issues.
