When I update code to this, with 

Thus, 
primitive_resolve("192.0.2.1", "rev.example.com")
is equivalent to
primitive_resolve("1.2.0.192.rev.example.com")

I am getting this error.
primitive_resolve: cannot resolve host name 169.214.85.209.

While dig is just fine (empty result)
dig +short @ns2  186.130.2.198.rev.example.com

Changing code to this string res resolve("186.130.2.198", "rbl.example.com")
returns nothing 

While dig gives me 
[]# dig +short @ns2  186.130.2.198.rbl.example.com
127.0.0.2

Somehow it looks like this resolving is not working, but match_dnsbl ($client_addr, "zen.spamhaus.org", "ANY" is doing fine.
