The sending IPs used by spammers have nothing in common with their
domain MXes. They just send from wathever IP they see fit. All they have
in common is an MX record for their domain listening at the same IP. So
having a blacklist who will be able to tell something like "all domains
that have their MXes pointing to this particular IP are spammer domains"
would be great.
