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

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.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (30s), MX (30s), NS (30s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 30s; resolvers may use either.

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: vade-mx-fr01.hornetsecurity.com, vade-mx-fr02.hornetsecurity.com, vade-mx-eu-fallback01.hornetsecurity.com, vade-mx-eu-fallback02.hornetsecurity.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), k1 (1024 bits). Rotate to a 2048-bit key.

TLS · With mode: testing, senders only report TLS problems (via TLS-RPT) and still deliver without TLS. Switch to mode: enforce once reports are clean.

TLS · These MX hosts are not listed in the MTA-STS policy (mx: mx02.cloud.vadesecure.com, mx03.cloud.vadesecure.com, mx04.cloud.vadesecure.com, mx01.cloud.vadesecure.com): vade-mx-fr01.hornetsecurity.com, vade-mx-fr02.hornetsecurity.com, vade-mx-eu-fallback01.hornetsecurity.com, vade-mx-eu-fallback02.hornetsecurity.com. This will break delivery once the policy is enforced.

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.
