Yup.  You'd have to "fake" a Received: header.  It's not very
efficient because you have to write the faked header, append the rest
of INPUTMSG, and then call SA on the result.

Frankly, I don't see much value in RBL's.  SpamAssassin by itself is
excellent at identifying spam; you probably wouldn't catch all that
much more by using a RBL.  When (if?) IPv6 ever becomes widespread,
RBL's will go from being marginally helpful to useless, because IP
addresses will be disposable.
