This is FAQ; I must add it to the file.

My view is: a sender verification is testing whether Exim could send a
bounce to that address. Therefore, it must use MAIL FROM:<> because that
is what it would do if it were sending a bounce message. If MAIL FROM:<>
is rejected, it means Exim could not send a bounce. Therefore the
callout fails.
