That matching in --server=/<domain>/..... has always been on whole
labels, since that's by far the most useful, in general. So you're right
that server=/-the-sub.example.com/ (with an implied wildcard on the
left, as always) won't match in you case: it would match
It may not be of immediate help to you, but the code which implements
this has been getting some attention recently, and partly prompted by
your suggestion, I have implemented a way to turn off whol-label
matching, using a * on the left. In the new code,
works as you expect. It's still in test, but if you want to try it, you
can download from the dnsmasq git repository.
