Problems

  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: sdns2.ovh.net (213.251.188.141): REFUSED, authoritative=false; sdns2.ovh.net (2001:41d0:1:4a8d::1): REFUSED, authoritative=false.
    #15
  • ✗
    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: sdns2.ovh.net (213.251.188.141): ; sdns2.ovh.net (2001:41d0:1:4a8d::1): .
    #19
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: sdns2.ovh.net. dns14.ovh.net, ns14.ovh.net report NS dns14.ovh.net ns14.ovh.net.
    #7
  • !
    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

  • ✗
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits), mail (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
