Problems

  • ✗
    Syntax errors
    SPF · Receivers reject the whole SPF record (permerror) because of: unknown mechanism "ip:5.196.164.210".
    #25
  • !
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    Applies to 20% of mail
    DMARC · DMARC policy only applies to 20% of failing mail (pct=20). Raise pct to 100 once you are confident in your setup.
    #18
  • !
    Subdomains unprotected (sp=none)
    DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.
    #20
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Unsupported report address
    DMARC · Receivers only send reports to mailto: addresses: postmaster@mairie-saint-ouen.fr.
    #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.
