Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    Policy not reachable
    TLS · The MTA-STS record exists but the policy could not be fetched, so senders ignore MTA-STS: Get "https://mta-sts.bistum-passau.de/.well-known/mta-sts.txt": dial tcp: lookup mta-sts.bistum-passau.de on 127.0.0.53:53: no such host.
    #33
  • !
    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: mx02.dioezesennetz.de, mx01.dioezesennetz.de
