SOA · The nameservers serve different versions of the zone: 2026101501 on 2.si-ns.fr (185.208.85.8), 2.si-ns.fr (2a00:1e70:1234:2::8); 2026102201 on 1.si-ns.fr (178.22.132.8), 1.si-ns.fr (2a00:1e70:1234:1::8). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (3m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1d; resolvers may use either.

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 166h0m0s). 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.
