Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-181.akam.net: "41824.5"; a1-181.akam.net: "41824.10"; a18-66.akam.net: "48878.31"; a18-66.akam.net: "48878.26"; a20-64.akam.net: "48878.27"; a20-64.akam.net: "48878.32"; a22-67.akam.net: "48878.31"; a22-67.akam.net: "48878.32"; a3-64.akam.net: "41824.9"; a3-64.akam.net: "41824.8"; a7-64.akam.net: "41824.9"; a7-64.akam.net: "41824.10". Hide or replace the version string.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-001ba401.gslb.pphosted.com, mxb-001ba401.gslb.pphosted.com, mx0a-001ba401.pphosted.com, mx0b-001ba401.pphosted.com

DNSSEC · DNSKEY signatures expire at 2026-10-25T03:03:01Z (in 64h0m0s). Check that re-signing works.

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.
