Filtering spam with rspamd

With a recent nightly release, apnscp now includes experimental rspamd spam filtering. rspamd will inevitably replace SpamAssassin as it's not only 3-5x faster than SpamAssassin with shortcircuiting enabled, but also provides excellent milter capabilities that can stop spam before slipping into the mail queue without needlessly complicating the stack or burning unnecessary CPU cycles. Better yet, rspamd scores across far more dimensions including fuzzy matches, neural learning, rate-limiting, dynamic reputations, and my favorite: greylisting.
