I suspect you probably don't need to use a separate acl for uribl_lookup
if you use a set of if/else conditions and the dnsbl lookup type, but
without seeing it I can't be sure (don't show me, I can't be bothered to
convert it for you). If that is the case, you can use forall/forany. But
considering the low likelihood of anyone other than you actually using
your recursive acl config, I suppose it wont do too much damage.
