Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: dns2.univ-lyon1.fr, dnsbis.entpe.fr. dns.univ-lyon1.fr, dns2.univ-lyon1.fr, dnsbis.entpe.fr, si-dns.entpe.fr report NS dns.univ-lyon1.fr dns2.univ-lyon1.fr dnsbis.entpe.fr si-dns.entpe.fr.

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 · The following MX hosts could not be resolved to IPv6 addresses: si-mx24.entpe.fr, si-mx26.entpe.fr, si-mx36.entpe.fr, si-mx37.entpe.fr

DKIM · These keys could not be parsed, so signatures made with them will fail: dkim (public key is not valid base64).

SPF · These ranges authorize tens of thousands of addresses or more: ip6:2603:1000::/24. Check that you really own and send from all of them.

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.
