I've configured BATV here. If any users get this problem then I
can enable it for them specifically. Any bounces for mails they
sent in the last few days will be lost, of course, but from then
on they are protected - bounces for non-locally generated e-mails
will be rejected at SMTP time.
I'd turn it on globally if it weren't for some nasty mailing list
software out there that uses the return path as the subscribe
address. :-(
It is fairly easy to add support in Exim - see, for example,
