Note
----
Version 2 of maradns is a authoritative only DNS server without the
resolver part. The recursive and caching DNS resolver from the same
author, called deadwood, is available as a separate port now. See the
tutorial in [1] how both can work together. Using the DNSSEC capable
unbound instead of deadwood might be an option as well.
