Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: asia3.akam.net: "48878.32"; eur2.akam.net: "48878.26"; eur5.akam.net: "48878.29"; eur6.akam.net: "41824.8"; ns1-242.akam.net: "41824.9"; ns1-242.akam.net: "41824.7"; ns1-8.akam.net: "41824.7"; use1.akam.net: "48878.29"; use4.akam.net: "48878.27". Hide or replace the version string.

SOA · refresh 5m is outside 20m–1d; retry 5m should be shorter than refresh 5m; expire 5m is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 5m must be longer than refresh + retry. Current values: refresh 5m, retry 5m, expire 5m, negative TTL 5m.

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: A (20s), 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.

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

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

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

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

DMARC · DMARC policy only applies to 10% of failing mail (pct=10). Raise pct to 100 once you are confident in your setup.

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.
