  • ✗
    No nameserver responds
    Nameservers · None of the nameserver addresses answered: ns1pub.sfr.fr (92.90.26.129): read udp 46.225.38.91:52157->92.90.26.129:53: i/o timeout; ns2pub.sfr.fr (92.90.26.145): read udp 46.225.38.91:54585->92.90.26.145:53: i/o timeout.

    Nameservers in one network
    Delegation · all IPv4 addresses are in 92.90.26.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    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: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: smtp-in.sfr.fr
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
