Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dawn.ns.cloudflare.com: "2026.10.2"; kip.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    DMARC not strict enough for BIMI
    BIMI · Mail clients will not show the logo. BIMI requires DMARC p=quarantine or p=reject (now p=none), DMARC pct=100, a subdomain policy other than sp=none.
    #39
  • !
    Unreadable DKIM key
    DKIM · These keys could not be parsed, so signatures made with them will fail: k1 (public key is not valid base64).
    #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.
    #32
  • !
    No certificate (a=)
    BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
