    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-16.akam.net: "41824.11"; a1-16.akam.net: "41824.6"; a16-65.akam.net: "48878.29"; a16-65.akam.net: "48878.32"; a22-67.akam.net: "48878.26"; a22-67.akam.net: "48878.33"; a28-66.akam.net: "48878.26"; a28-66.akam.net: "48878.32"; a3-65.akam.net: "41824.5"; a3-65.akam.net: "41824.8"; a5-67.akam.net: "41824.8"; a5-67.akam.net: "41824.7". Hide or replace the version string.

    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 10 iterations and a 10-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.

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
  • !
    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 75h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-25T18:24:38Z (in 75h0m0s). Check that re-signing works.
    #21
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector2 (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.
