If you're going to use a dnsbl, anybody's dnsbl, figure out how to whitelist first (or real soon after), because this sort of thing will happen from time to time.
Or learn how to tell people that spam is evil and under no circumstances will you accept spam from a system that sends it out in mass volume. If an AS became insecure and could start allowing anyone to setup new netbock advertisements from it, you would filter out the AS. If it was small, you might hardcode in the valid netblocks, but when it's a large AS, you tend just to shut it all down. Such is the way with smtp. -- -Jack
