You are always at the mercy of the data provider when using dnsrbls and
such. Those who input the data determine what constitutes spam and the
spam sources, etc. Sometimes they add entire IP ranges, and this usually
causes problems. Dnsrbls and domain rbls are a good line of defense, but
both have their faults. Spammers change both domains and IPs as some as
they're listed.

Thanks. In other words, it's pretty much useless to me because of false
positives. Does anyone else use this feature and if so, do find that you get
a lot of false positives? I am finding that they have a lot of Time Warner's
servers on the list and unfortunately a lot of our customers use Time Warner
and I can't afford to lose emails from them.
