amavisd-new can be and is regularly used in a pre-queue filtering setups, especially since the advances in a warm-reload and tighter time limiting control on SpamAssasasin 3.3 combined more recent versions of amavisd. These advances go hand-in-hand with a Postfix 2.7.0 new option smtpd_proxy_options=speed_adjust. In a pre-queue filtering setup amavisd can do a proper D_REJECT right on the incoming SMTP session, just like a milter can (but offer added flexibility). Mark
