You can't count like this. because what is rejected by zen is not
checked against the other two.
changing the order of the checks will give you different numbers.
the only way to get real numbers is to put
warn_if_reject reject_rbl_client $list1
warn_if_reject reject_rbl_client $list2
warn_if_reject reject_rbl_client $list3
before the actual rejects. This way you can count the reject_warning log
lines. now this means more lookups (you will lookup all the DNSBLs,
instead of stopping at first listing).
