Problems

  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns2.observatoiredesmarques.fr (188.122.87.39): EOF; ns2.observatoiredesmarques.fr (2a00:1630:210:3::39): EOF.
    #19
  • !
    Not signed
    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.

    Reverse DNS does not match
    MX · The PTR name of these addresses does not resolve back to the same address: 2001:4b98:dc4:8::217 -> spool8.mail.gandi.net, 2001:4b98:dc4:8::215 -> spool6.mail.gandi.net, 2001:4b98:dc4:8::216 -> spool7.mail.gandi.net, 2001:4b98:dc4:8::216 -> spool7.mail.gandi.net, 2001:4b98:dc4:8::215 -> spool6.mail.gandi.net, 2001:4b98:dc4:8::217 -> spool8.mail.gandi.net.

    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.
