I agree that the server behaviour should be corrected. The question
is: how many name servers out there exhibit this error? If only
the servers for www.newegg.com and www.usps.com are broken, then
I agree that putting this work-around in the resolver is unnecessary
and perhaps even harmful. If they are just the tip of an iceberg,
then the work-around is needed. Otherwise sites that try to deploy
Unbound will find themselves dealing with user complaints for which
the convenient solution will be to revert to BIND.
I don't know how often this misconfiguration occurs. It would be
interesting to obtain the logs from a high-traffic resolver that
hasn't blackholed lame server logging. One clue, though: PowerDNS
Recursor appears to have the same work-around as BIND:
