  • ✗
    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.xaq.nl (192.87.112.194): dial tcp 192.87.112.194:53: i/o timeout; ns2.xaq.nl (192.87.112.196): dial tcp 192.87.112.196:53: i/o timeout; ns3.xaq.nl (192.87.39.204): dial tcp 192.87.39.204:53: i/o timeout; ns4.xaq.nl (213.125.58.51): dial tcp 213.125.58.51:53: i/o timeout; ns5.xaq.nl (31.3.109.171): dial tcp 31.3.109.171:53: i/o timeout; ns6.xaq.nl (31.3.109.172): dial tcp 31.3.109.172:53: i/o timeout.

    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #4
  • !
    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: selector2 (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.
