Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.ungrounded.net: "PowerDNS Authoritative Server 5.1.5 (built Oct 7 2026 06:13:02 by root@localhost)"; ns2.ungrounded.net: "PowerDNS Authoritative Server 5.1.5 (built Oct 7 2026 06:13:02 by root@localhost)". Hide or replace the version string.

SOA · refresh 15m is outside 20m–1d; negative caching TTL (minimum) 1m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 15m, retry 5m, expire 14d, negative TTL 1m.

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 (55s), MX (1m), NS (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1m; 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 · Found 7 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.

DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.

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.
