Yes, of course...

*My* definition of incoming is "coming into Exim either from port 25
or the command line", and outgoing is "being delivered either to another
host or a local user".
Re-read the install doc with that in mind and it should make sense.

You sound horribly confused. The way to make it work is to configure Exim
with no mailscanner at all. Then add mailscanner.
Mail is generally not routed on the basis of where it is from (as you seem
to think you want above), but on where it is supposed to end up. This
usually makes sense.

OK, what you probably want (vaguely, I don't want to go into details like
"where do you want mail for root on the mailscanner box to go?") is no
local domains on the mailscanner box, with and a router using the
domainlist driver to route mail for <any domain that's handled by the internal
box> to the internal box, and everything else to the external box.
driver = domainlist
transport = remote_smtp
route_list = *.internal.domain name.of.exchange.server byname; \
! *.internal.domain name.of.smarthost byname
But don't just trust me; make sure you understand it.
Once you have exim set up right, add mailscanner.

Communicate! It can't make things any worse.
