''FEATURE(dnsbl)'' '''


Reject based on various DNS blacklists V8.10 and above

The original feature was called rbl and caused hosts listed with the original "real-time blackhole list" to be rejected. That feature has been deprecated and replaced by this new dnsbl feature. With this new feature you can have hosts rejected by any number of real-time blackhole lists, including or excluding the original. This feature is fully described in Section 7.2.
