Right, though it does not (AFAICT) do any checks on the local part. Exim
would happily say that foo@??? is a valid sender
address, despite the fact it cannot be mailed to. (I don't see how it
could verify the local part anyway, many sites to not implement VRFY
and blindly respond 250 to all RCPTs.)

What about headers_sender_verify? True, header checks are pretty much
useless since you've already accepted the message by the time you can
process them, but never mind. It still might keep some shit out of my way.

I can't use either since all my mail comes from Demon's machines... not
fair :-(
