Problems

  • ✗
    No nameserver responds
    Nameservers · None of the nameserver addresses answered: ns1pub.sfr.fr (92.90.26.129): read udp 46.225.38.91:35814->92.90.26.129:53: i/o timeout; ns2pub.sfr.fr (92.90.26.145): read udp 46.225.38.91:47172->92.90.26.145:53: i/o timeout.
    #14
  • ✗
    DNSSEC validation fails
    DNSSEC · Validating resolvers return SERVFAIL for this zone, so the domain is unreachable for a large part of the internet. Check the DS record at the registrar against the zone's keys and the signatures.
    #27
  • !
    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.

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.
    #4
  • !
    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.
    #7
  • !
    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
  • !
    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:dmarc_report_agg@sfr.fr (needs noos.fr._report._dmarc.sfr.fr); mailto:dmarc_report_err@sfr.fr (needs noos.fr._report._dmarc.sfr.fr). Ask the report provider to publish the record, or check the address.
