After udate to lenny two DNS stopped workin, better, they bagan to have a
behaviour  "a la SMTP" .
hosts are in a.b.c.0/24 .
if a query arrive from an host in their localnet all ok, otherwise if the
querying machine is outside their localnet[s] the they supply the address
only if the supplied address in in a zone for which they are
official primary or secondary DNS.
otherwise no lich and in the log i find:

Mar  7 23:37:25 mydnsserver named[2248]: client 
     151.16.***.***#34363: query
     (cache) 'www.google.it/A/IN' denied

i copied etch configuration files ... did i make some error ?

they have to supply dns service to everyone.
