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

DNSSEC · The zone is signed but the parent has no DS record, so the signatures are not used. Publish the DS record at your registrar.

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

DNSSEC · The zone is signed (DNSKEY present) but the parent has no DS record, so the chain of trust is incomplete. Publish the DS record at your registrar.

MX · The following MX hosts could not be resolved to IPv6 addresses: mail-5760.worldnet.fr

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

DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...

DKIM · These keys could not be parsed, so signatures made with them will fail: default (public key is not valid base64).

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.
