New Features 9.9.4

   Added Response Rate Limiting (RRL) functionality to reduce the
   effectiveness of DNS as an amplifier for reflected denial-of-service
   attacks by rate-limiting substantially-identical responses. [RT
   #28130]

I have been using this since 9.9.4bx, and although documentation is/was
lacking at the time, so there might be a whitelisting somewhere , but in
its absence, I highly advise against using RRL if your mail servers use
those DNS servers
