Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: lily.ns.cloudflare.com: "2026.10.2"; will.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

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 (1m), AAAA (1m). 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.

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: mx1-eu.emailsecurity.app, mx2-eu.emailsecurity.app

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

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits). Rotate to a 2048-bit key.

MX · The PTR name of these addresses does not resolve back to the same address: 132.164.188.153 -> mx2-eu.emailsecurity.app, 4.245.183.72 -> mx1-eu.emailsecurity.app.

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.
