Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns-ext1.mines-ales.fr: "BIND 1.0 ZX-80 Port"; dns-ext2.mines-ales.fr: "BIND 1.0 ZX-80 Port". Hide or replace the version string.

SOA · refresh 10m is outside 20m–1d; retry 1h should be shorter than refresh 10m; negative caching TTL (minimum) 2d is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 10m, retry 1h, expire 7d, negative TTL 2d.

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.

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

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: mx.mines-ales.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:...

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.
