    We host the domain example.com. Since Dec. 26 2016 no emails being received on the domain. When an email is send to the domain there's no error either.

    A look at - Removed - shows many DNS errors, indicating there's a problem. But a look at the DNS settings for domain on the server shows there's no problem. Both NS and MX records are in place.

    What could be causing DNS errors?

    If MX records is a problem how comes there's no bounce message?

    Since the issue is critical, I decided to open a support ticket:

    You should check your nameserver settings at your Domain Name Registrar.

    I don't see any problem.

    What am I supposed to be looking for?

    Nameservers at your Registrar not being setup, or setup incorrectly somehow. There is a problem, you saw it.

    The name servers have been running for 2 years without a problem.

    On the registrar the name servers are specified and their IP addresses. What else is supposed to be specified?

    My guess is there's a problem with named but don't know how to pinpoint it.

    On DNS problem - One or more of your nameservers did not respond the person says the problem can be resolved using the following on named:

    allow-query { all; };


    But I checked named and didn't see any such entry:

    # cat /etc/named.conf | grep allow-query

    # less /etc/named.conf | grep allow
    inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; };
    /* make named use port 53 for the source of all queries, to allow
    // Put files that named is allowed to write in the data/ directory:
    allow-transfer { "none"; };
    // All BIND 9 zones are in a "view", which allow different zones to be served

    Are there any other domains on this server having the issue or is it just this one?

    All other domains can send/receive emails except this one.

    But looking at intodns.com/ most of them show the DNS errors.

    Hello,

    To update, it was determined the missing emails were due to an email filter added to the account that discarded previously undelivered emails.

    Thank you.
