Re: what the heck do i do now?

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Personally I have no sympathy to people who are using outdated dnsbl's 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).
