    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-230.akam.net: "41824.5"; a1-230.akam.net: "41824.4"; a12-67.akam.net: "48878.33"; a12-67.akam.net: "48878.29"; a2-64.akam.net: "48878.30"; a2-64.akam.net: "48878.32"; a20-66.akam.net: "48878.27"; a20-66.akam.net: "48878.33"; a3-66.akam.net: "41824.11"; a3-66.akam.net: "41824.4"; a7-66.akam.net: "41824.6". Hide or replace the version string.

    Unusual SOA timers
    SOA · retry 1h should be shorter than refresh 1h. Current values: refresh 1h, retry 1h, expire 14d, negative TTL 1d.
    #23
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m), MX (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1d; resolvers may use either.

    Signatures expire in 68h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-25T12:39:40Z (in 68h0m0s). Check that re-signing works.

  • !
    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
  • !
    Not configured
    TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
