Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns3.cliss21.com (90.63.235.138): read udp 46.225.38.91:50369->90.63.235.138:53: i/o timeout.
    #14
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.cliss21.com: "9.18.49-1~deb12u2-Debian"; ns2.cliss21.com: "9.18.49-1~deb12u2-Debian"; ns3.cliss21.com: "9.18.49-1~deb12u2-Debian". Hide or replace the version string.
    #17
  • !
    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

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

    Hosts without IP addresses
    MX · The following MX hosts could not be resolved to IP addresses: mx0.mailinblack.com
    #10
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: asp25.mailinblack.com, mx0.mailinblack.com
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 52.143.158.11 (asp25.mailinblack.com). Ask your hosting provider to set one.
    #30
  • !
    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.
