    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-191.akam.net: "41824.5"; a1-191.akam.net: "41824.10"; a12-66.akam.net: "48878.29"; a12-66.akam.net: "48878.27"; a28-64.akam.net: "48878.31"; a28-64.akam.net: "48878.32"; a3-66.akam.net: "41824.4"; a3-66.akam.net: "41824.9"; a4-65.akam.net: "48878.30"; a4-65.akam.net: "48878.27"; a7-66.akam.net: "41824.8"; a7-66.akam.net: "41824.10". Hide or replace the version string.

    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 20 iterations and a 14-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

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

    Signatures expire in 85h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-25T10:23:24Z (in 85h0m0s). Check that re-signing works.

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.

  • !
    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:...".
