I certainly did get an error originally. I would not have found this 
page if I didn't have the error message to search for.

After reviewing my command history I have concluded that it is possible 
that I originally tested with an A, not TXT record, thusa causing the 
error. Then I switched it, unaware of the difference to check-names.

Thanks for the in-depth 'proof'. I have removed check-names now and it
works as it should.
