FEATURE(dnsbl)
Synopsis
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.
