resolver cache). For the second and later answers, you don't get an
authoritative answer (because the answer comes from the resolver's

PowerDNS recursor gives you a non-authoritative answer even if it has
just received this answer from the authoritative server. IMHO this is
just as correct as the BIND behavior.

Personally I find the BIND behavior moderately confusing, and the
PowerDNS recursor behavior less surprising.
