So this is not consistent with what was logged. You reported Mailman's error log has DNSException: No Nameservers available for usern...@blindeforbundet.no (_dmarc.blindeforbundet.no) That message is only logged if the resolver.query() raises dns.resolver.NoNameservers. dns.resolver.NXDOMAIN is the expected result when there are no records at _dmarc.blindeforbundet.no and results on no mitigation. If this is a persistent error from Mailman, and Mailman is running on the same server you ran the above on, I can't explain it, but possibly is was just a transient situation and the mail from this user will now be accepted. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
