I guess I don't understand the problem, then.

In general, it's the resolver's job to append a default domain to an
unqualified name, not the server's job.  For instance, if your
/etc/resolv.conf contains

domain shifted-bytes.de

and you try to look up "banana", the resolver library should try to look up
"banana.shifted-bytes.de".  Since this domain should be in your server's
database, it should give an authoritative answer, and no recursion should
take place.

If you try to look something up in an outside domain,
e.g. banana.bbnplanet.com, your server should perform a recursive query to
our server.
