Problems

  • ✗
    11 DNS lookups, over the limit of 10
    SPF · SPF record needs 11 DNS lookups (including nested includes), more than the limit of 10. Receivers will return a permerror; reduce includes or flatten the record.
    #2
  • ✗
    No DKIM keys published
    DKIM · _domainkey.museeduluxembourg.fr does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mailhost2.rmn.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:postmaster@grandpalaisrmn.fr (needs museeduluxembourg.fr._report._dmarc.grandpalaisrmn.fr). Ask the report provider to publish the record, or check the address.
    #29
  • !
    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.
