[Declude.JunkMail] Blacklist effectiveness

[Darin Cox]

Anyone else noticing over the past few months that DNSBLs and RHSBLs have almost completely lost their effectiveness?   We're seeing only a few (e.g. SBL, MXGATE, MAILPOLICE) that catch more than 5% of incoming spam, and they top out at less than 6%.   If it weren't for Sniffer and the specialized tests in Declude we'd be buried.   Just curious as to what others are seeing...
