Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns3.belnet.be. ns1.belnet.be, ns2.belnet.be, ns3.belnet.be, nsmaster.belnet.be report NS ns1.belnet.be ns2.belnet.be ns3.belnet.be nsmaster.belnet.be.

SOA · retry 2h should be shorter than refresh 2h. Current values: refresh 2h, retry 2h, expire 14d, negative TTL 5m.

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.

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits). Rotate to a 2048-bit key.

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.

BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
