I don't think it is (at least not yet).

As for the bounce message, it only says "host -t MX", because, as I have
already stated, I couldn't write a book, there is limited space in there.

postmaster of the remote domain.

As far as SMTP callback is concerned, exim of course checks MX first and
then A.
