Which kind of test did you have in mind? Sorry if I'm missing the
point, but, as far as I can make out, it behaves in -bt and -bh just
the way I intended it to.

Well, -they- will have no problem contacting -our- postmaster, since
we don't impose the verify=sender condition for incoming mail to
our postmaster address.
As long as their IP is blocked in our ignore_spammers list, our exim
would refuse to mail their postmaster - claiming that their domain is
unreachable - as we intended it to do! But if we wanted to talk to
their postmaster, that would presumably be because we didn't wish to
block them any more, no?
