Problems

  • !
    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns.rtlnet.fr (glue 92.61.160.150, zone 92.61.160.150, 2a03:4600:7112::96). Update the glue at your registrar.
    #8
  • !
    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.

Problems

  • ✗
    Weak DKIM key
    DKIM · RSA keys shorter than 1024 bits can be cracked and are ignored by receivers (RFC 8301): mx (512 bits). Rotate to a 2048-bit key.
    #23
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx1.m6.fr, mx2.m6.fr
    #11
  • !
    Key in test mode
    DKIM · These keys have t=y, so receivers treat DKIM failures as a test: mx. Remove t=y once DKIM works.
    #24
  • !
    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.
