Registration · The registration expires on 2026-11-18. Make sure it is renewed.

Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

SOA · The serial 2089122112 looks like a date (YYYYMMDDnn) in the future (2089-12-21). It can only grow, so a wrong date can't be undone without a serial wrap-around.

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.

SPF · The ptr mechanism in SPF records is deprecated due to performance issues and should be avoided.

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 · The following MX hosts could not be resolved to IPv6 addresses: antispam.vpc2.osc.interstis.fr, antispam.vpc2.osc.interstis.fr

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

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.
