removing check for rulenames

[Spamassassin List]

Hi,

How do I remove checking with RCVD_IN_DNSWL_LOW and RCVD_IN_RP_SAFE        

-0.7 RCVD_IN_DNSWL_LOW      RBL: Sender listed at http://www.dnswl.org/, low
                            trust
                            [67.131.25.23 listed in list.dnswl.org]
-2.0 RCVD_IN_RP_SAFE        RBL: Sender is in Return Path Safe (trusted
relay)
                            [Return Path SenderScore Safe List (formerly]

Thanks with regards
