Has anyone ever implemented BATV[0] in exim config? It seems to me like
it would (mostly) solve the same problems as SPF, at least from the
senders point of view, without requiring the involvement of any other
servers to be effective.

If anyone's got a working implementation, or documentation of how that
kind of thing could be done in exim config, or for that matter a reason
to beleive it can't be done, I'd be interested to know.
Thanks,
