Assunto: Reverse dns checking for local machine

I know there's been discussion of the perils of validating connections
on the basis of dns mismatch, but I think it would be a good idea if
exim could at least be set to check on an outside machine claiming to be
the mail host exim is running on itself. I've seen several auto-spam
programs now that seem to be set to claim to be the machine they are
connecting, as a sneaky way of avoiding blocking lists.
