I’m having a hard time hosting my own BIND DNS. can someone please let me know if I’m doing something wrong?
I have my domain name registered with my provider (register.com).
I have created “A” records for my name servers in a different resource domain that I own and manage (call it ns1.resourcedomain.com, ns2.resourcedomain.com pointing to my BIND server ip addresses).
On the BIND servers, I have created the zone file without issue.
NSLOOKUP queries to my BIND servers return “A” records and “MX” records without issue.
If I do DNS checks using services (mxtoolbox for example), it reports that my DNS servers do not respond or timeout.
I am able to receive email from all domains EXCEPT (1) customer domain. This customer’s domain reports that our DNS is invalid.
How could NSLOOKUP respond correctly, I receive email from most domains, and my www “A” record responds OK, but (1) single domain cannot? Also why would a service like MXTOOLBOX report that I’m timing out? The error I get from MXTOOLBOX is:
DMARC Record Published No DMARC Record found
DNS No Valid NameServers Responded Not able to get a response from name servers within timeframe
Help is appreciated, thanks!
