Unusual SOA timers

SOA · retry 1d should be shorter than refresh 1h; negative caching TTL (minimum) 7d is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 1h, retry 1d, expire 224h, negative TTL 7d.

#23
!

Deprecated algorithm

DNSSEC · SHA-1 based algorithms are deprecated and rejected by some validators: RSASHA1-NSEC3-SHA1 (7). Roll over to ECDSAP256SHA256 (13).

#29
!

NSEC3 with extra iterations or salt

DNSSEC · NSEC3 uses 10 iterations and a 8-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

Problems

✗

No DMARC record

DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.

#5
✗

No DKIM keys published

DKIM · _domainkey.f8kgk.fr does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.

#7
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: mail.f8kgk.fr

#11
!

Single MX host, no backup

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

#12
!

Not configured

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.
