We gave up trying to induce Exim to do lookups the way we wanted, and
instead run a Python daemon to do them for us and return the sorts of
results we want. We didn't like Exim's treatment of various forms of lookup
error.

Exim is essentially unchangeable in this regard at this point...too many
existing configurations.
