Problems

  • ✗
    DMARC not strict enough for BIMI
    BIMI · Mail clients will not show the logo. BIMI requires a subdomain policy other than sp=none.
    #39
  • !
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxa.thieme.de, mxb.thieme.de, mxc.thieme.de, mxd.thieme.de, mxe.thieme.de, mxf.thieme.de
    #11
  • !
    More than 5 MX records
    MX · Found 6 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.
    #13
  • !
    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
  • !
    No certificate (a=)
    BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
