dnslists = list1.example doesn't mean "if the (nonexistant) variable
dnslists equals list1.example". Rather, it means "if a lookup of the
calling host in the dns RBL list1.example succeeds". So the deny you
quote above will be executed if the host can be resolved in both dns
RBLs list1.example AND list2.example. The A=B syntax in exim ACLs is a
bit strange at first, but you get used to it pretty quickly.
