Or just have everydns [or insert other free dns provider] handle your
primary dns and let them handle the traffic, problem solved (for you
atleast) :-)
Personally I have no sympathy to people who are using outdated dnsbl's
(especially from 1999), I would consider the wildcard if you want to
actually solve the problem instead of dealing with it yourself or having to
hand it off to someone else.
You may also take that list of ips (with over 100 queries or so) and turn on
the dnsbl with those ips added (they will only reject mail from each other
but it might give some a clue).
