I'm not a bind user/expert but (somebody pls verify this), to run 
without having to change SA rules  this should looks like:
(I use PDNS)


zone "zen.spamhaus.org" {
       type forward;
       forward only;
       forwarders {
          XXXXXXX port 10099;
        };
zone "sbl.spamhaus.org" {
       type forward;
       forward only;
       forwarders {
          XXXXXXX port 10099;
        };
zone "xbl.spamhaus.org" {
       type forward;
       forward only;
       forwarders {
          XXXXXXX port 10099;
        };
zone "sbl-xbl.spamhaus.org" {
       type forward;
       forward only;
       forwarders {
          XXXXXXX port 10099;
        };
zone "dbl.spamhaus.org" {
       type forward;
       forward only;
       forwarders {
          XXXXXXX port 10099;
        };
