Only at one level. Set up your mail hub to the primary host(s), and use
fallback_hosts to specify the secondary host(s).

It tries them in order, unless you set hosts_randomize. You are right.
It doesn't seem to say this very clearly...

One thing that is missing from Exim 4 is the ability to say "route
domain X as if it were domain Y". This is on the Wish List. If it were
implemented, you could just set up MX records for "domain Y".
However, the possible idea of having host priorities specified
explicitly (as opposed to getting them from MX records) is new. I've put
that on the WishList too.
The Wish List is growing rapidly, but I do hope to start to tackle some
of it once I've got this book out of the door.
