  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns1.namecity.com (62.128.193.35): REFUSED, authoritative=false.

  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.namecity.com (62.128.193.35): .
    #19
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.namecity.com. ns-1343.awsdns-39.org, ns-15.awsdns-01.com, ns-2044.awsdns-63.co.uk, ns-731.awsdns-27.net report NS ns-1343.awsdns-39.org ns-15.awsdns-01.com ns-2044.awsdns-63.co.uk ns-731.awsdns-27.net.

Problems

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
