--------------------------------+-------------------------------------------
 The Tor resolver sends an empty reply (status: NOERROR, QUERY: 1,
 ANSWER: 0) rather than an error when it does not support the type of
 the query (e.g. MX). This makes it impossible to setup a transparent
 torifying DNS proxy frontend that would ask Tor by default, and
 fallback to ttdnsd for DNS query types that are unsupported by the
 former.
