I tried the code on my system as well, and get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.7/site-packages/dns/resolver.py", line 1002, in query
raise NXDOMAIN(qnames=qnames_to_try, responses=nxdomain_responses)
dns.resolver.NXDOMAIN: None of DNS query names exist:
_dmarc.blindeforbundet.no.
, _dmarc.blindeforbundet.no.lamasti.net.
