You may find inserting the RBL in sendmail as a successful choice. In case you do not, What I use is a combination of scoring within SpamAssassin on the public RBLs and maintaining my own RBL on my local mail servers (See http://www.corpit.ru/mjt/rbldnsd.html). I got too many false positives off publicly available RBLs, but adding up the number of RBLs a sender 'hits' made my SpamAssassin scoring method VERY ACCURATE! Good luck and keep fighting! ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
