Thanks for this hint. There's a point I missed and now I got (I think) .
I thought that a check toward an rbl was similar to what on a shell would
be:

  $ host    ip_to_be_checked     my.preferred.rbl.org

while enabling named querylog and using rblcheck I see that is like this:

  $ host    ip_to_be_checked.my.preferred.rbl.org
  
so now I understand your configuration.

Thanks

PS: as far as using rbldnsd or not... reading spamhouse FAQ it seems that we
    are not even entitled to use the free servers from spamhouse...
