Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: sierra.ns.cloudflare.com: "2026.10.2"; tom.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

  • !
    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
  • !
    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.
    #8
  • !
    Applies to 5% of mail
    DMARC · DMARC policy only applies to 5% of failing mail (pct=5). Raise pct to 100 once you are confident in your setup.
    #18
  • !
    Unreadable DKIM key
    DKIM · These keys could not be parsed, so signatures made with them will fail: mail (public key is not valid base64).
    #23
  • !
    Policy in testing mode
    TLS · With mode: testing, senders only report TLS problems (via TLS-RPT) and still deliver without TLS. Switch to mode: enforce once reports are clean.
