[Pdns-users] DKIM NXDOMAIN

[Bart Mortelmans]

Hi,

It seems like this doesn't cause any problems in the real world, only in 
a test like the one on internet.nl. But as far as I can tell, it's not 
okay with RFC8020. And I tested some other nameservers (Google cloud 
DNS, Dyn.com and Yadifa happened to be easy to test for me) and I can 
confirm that they all do return "NOERROR" instead of "NXDOMAIN" if a 
sub-host exists.

The situation still seems to be the same in the upcoming PowerDNS 4.2 
with MySQL backend (I didn't test other backends)

The only solution to this "problem" (or to get through the test...) I 
have found was to create any other record type on _domainkey (obviously 
not CNAME or NS, but any other record type should be okay).

Sincerely,
Bart Mortelmans
