Yes, saned uses gethostbyaddr() and similar functions. With the new way
to check the client, also IP addresses can be entered into saned.conf,
however gethostbyaddr is always called, if the client is not localhost.
So name resolution must work. This can also be done using a name
server, no /etc/hosts necessary.

I think this is a bug. I will think about how we can avoid this. Maybe
an additional check if "+" is present at before the first lookup?

That's just the way it works since I know saned. I thin you must ask
Andreas Beck what he thought about it.

I will add a TODO entry about this. I don't think it's that easy to
fix. Patches are welcome :-)

If I remember correctly, you are the first person who reported this
misfeature so I wasn't aware that it could be a problem.
