That's great advice. I have found over the years that DNSWL is well run, and I'm confident that if a listed machine is emitting spam and it's reported, then it would either get delisted or fixed very fast. > You first might want to verify that your FPs aren't being generated by > some upstream relay that is is trusted but due to some configuration > issue is "masking" the spam source.

Putting the spam in a pastebin will let other people do a test scoring run and that will likely shed some light on the situation. Also, check how your DNS is set up. While DNSBLs in general don't want to return false results on purpose, when they get abused with high query rates there are not a lot of options to get people to stop.
