Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: chris.ns.cloudflare.com: "2026.10.2"; lucy.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.
    #17
  • !
    Signed but not delegated securely
    DNSSEC · The zone is signed but the parent has no DS record, so the signatures are not used. Publish the DS record at your registrar.

Problems

  • !
    Signed, but no DS at parent
    DNSSEC · The zone is signed (DNSKEY present) but the parent has no DS record, so the chain of trust is incomplete. Publish the DS record at your registrar.

  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

  • !
    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.
