Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • !
    Ends with ?all (neutral)
    SPF · SPF record uses ?all (neutral), which gives no protection against unauthorized senders. Use -all or ~all instead.
    #3
  • !
    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: filtrer.avecnous.eu
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Report address not authorized
    DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:demarquer@avecnous.eu (needs expertes.fr._report._dmarc.avecnous.eu). Ask the report provider to publish the record, or check the address.
    #29
  • !
    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.
    #30
  • !
    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.
