RE: [exim] relay and final rejection for exchange org.

Its not clear to me how that would prevent mail loops caused by mail
originating inside the organization and allow traffic between them. Are
you suggesting two lists defining who is on which exchange box?

How about using "Restricting routers to specific senders" on page 100.
Could I restrict use of the incoming internet router from the exchange
servers (or vice versa)? I'm looking for an example now.

Thanks for the reply.
