That host name does show up in your e-mail headers. That may
be why there are some people curious about that host name.
If the repeat traffic really bothers you, I'd bet that you could
get them to go away by giving a better answer than "REFUSED"
to their query. If you want to keep your private.tamay-dogan.net
zone private, you could use views to keep the zone from existing
for the Internet side of your connection.
I'd even be tempted to ditch the allow-query ACL so that they could get
the michelle1.private.tamay-dogan.net/A/IN == 192.168.0.65 answer (at
least temporarily).
I'd be even more tempted to ignore the noise in your log file. BIND is
just letting you know it is doing exactly what you configured it to do.
