If you configure multiple name servers via -nameserver=10.10.10.2:53,8.8.8.8:53 and try to resolve a name that does not end in .docker (or whatever you have configured -domain to be) you will see that it only tries the first server, prints a log message that it is trying the next server, but then just sends the failure response and returns.
PR #73 will try all name servers and will only fail when each of those name servers have failed to resolve.
