Yes, that's basically it. Because so many spammers give fictive
addresses, IP literals are paramount. Exim's standard check, as we use
it, will look up an IP literal from a domain literal. If he can't find
it, he'll check in an exception list that we give him. If the IP
number's not in that, he'll refuse the mail with a 220, postmaster can
still be contacted. That last would be out with what we want to to with
relayed spam, since he'd simply accept the mail and save it to a
cesspool.

That would be great.

As far as I can see from rfc822, section 6, this pertains to domain
literals, not to IP literals. So foranyaddress wouldn't work for us.
Though please correct me if I'm wrong; please?
