Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.global.hub-one.net, ns2.global.hub-one.net, ns5.global.hub-one.net. ns1.global.hub-one.net, ns1.hubtelecom.net, ns2.global.hub-one.net, ns2.hubtelecom.net, ns5.global.hub-one.net, ns5.hubtelecom.net, ns6.global.hubone.fr report NS ns1.global.hub-one.net ns1.hubtelecom.net ns2.global.hub-one.net ns2.hubtelecom.net ns5.global.hub-one.net ns5.hubtelecom.net ns6.global.hubone.fr.

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.

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

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

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (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.
