Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-28.akam.net: "41824.6"; a1-28.akam.net: "41824.10"; a10-65.akam.net: "48878.32"; a10-65.akam.net: "48878.33"; a13-66.akam.net: "41824.7"; a13-66.akam.net: "41824.6"; a14-67.akam.net: "48878.33"; a14-67.akam.net: "48878.27"; a6-64.akam.net: "48878.30"; a6-64.akam.net: "48878.31"; a9-65.akam.net: "41824.6"; a9-65.akam.net: "41824.8". Hide or replace the version string.

SOA · refresh 15m is outside 20m–1d; retry 1h should be shorter than refresh 15m. Current values: refresh 15m, retry 1h, expire 28d, negative TTL 15m.

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.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: MX (2m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 5m; resolvers may use either.

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-0032c001.gslb.pphosted.com, mxb-0032c001.gslb.pphosted.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector2 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.

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.
