    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-71.akam.net: "41824.9"; a11-66.akam.net: "41824.10"; a11-66.akam.net: "41824.7"; a13-67.akam.net: "41824.4"; a13-67.akam.net: "41824.8"; a18-64.akam.net: "48878.29"; a18-64.akam.net: "48878.32"; a22-65.akam.net: "48878.29"; a22-65.akam.net: "48878.30"; a6-66.akam.net: "48878.27"; a6-66.akam.net: "48878.33". Hide or replace the version string.

    Unusual SOA timers
    SOA · expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 2h, retry 1h, expire 1d, negative TTL 1h.
    #23
  • !
    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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), AAAA (20s). Low TTLs are useful just before a planned change.

Problems

  • ✗
    13 DNS lookups, over the limit of 10
    SPF · SPF record needs 13 DNS lookups (including nested includes), more than the limit of 10. Receivers will return a permerror; reduce includes or flatten the record.
    #2
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: dkim (1024 bits), selector2 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.
    #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.
