Understood, but this doesn't prevent someone from making a mistake
when creating its configuration file... and if the resolver has more
than one host (including yours), then failure from your machine will
simply let him skip to next host, which in fact only slows down DNS
resolution. Thus, people are likely to live with a broken configuration
for long...

Collect the source IP(s), find the admin and send him an email...
