Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns.inwx.de, ns2.inwx.de, ns3.inwx.eu; only in the zone: ns1.un-hack-bar.de, ns2.un-hack-bar.de, ns3.un-hack-bar.de. ns.inwx.de, ns1.un-hack-bar.de, ns2.inwx.de, ns2.un-hack-bar.de, ns3.inwx.eu, ns3.un-hack-bar.de report NS ns1.un-hack-bar.de ns2.un-hack-bar.de ns3.un-hack-bar.de.

DNSSEC · The earliest signature expires at 2026-10-29 00:00 UTC (in 167h0m0s). Check that automatic re-signing works.

DNSSEC · NSEC3 uses 1 iteration and a 1-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.

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

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

DNSSEC · DNSKEY signatures expire at 2026-10-29T00:00:00Z (in 167h0m0s). 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.
