I'm afraid if you want to call out to some and not others, you'll have
to find some way of differentiating them.

Or you could periodically generate a list of the domains and copy it
over, so the secondary MX keeps doing the right thing if the MySQL
server falls over (which might be the reason the primary MX isn't working).

You might, as a matter of policy, insist that anyone you're acting as
secondary MX for should accept callouts from you. These are of course
calls-forward, not callbacks, so there's no religous war here; it should
help them reduce spam so should be no hardship, and should also reduce
load on your server.

Personally I think that this should be the default Exim configuration.
