Hmmm.... I guess that all depends on how you define "very high rate
of false positives". I guess it also depends on how you handle false
positives. With SpamAssassin (THANKYOU!), a false positive on a
single DNSBL rarely is enough to flag the email as spam. When
Osirusoft decided to "list the world", no harm was done on several
systems that I have detailed knowledge of.
Anyway, I doubt that RHSBLs will have a substantially lower false
positive rate. I think they will be very good indicators anyway.
