Checks

  • !
    Not configured
    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.

    Not configured
    TLS-RPT lets senders report TLS delivery problems to you. It is most useful together with MTA-STS or DANE.
    #35
  • !
    Not all MX hosts use DANE
    These MX hosts publish no TLSA records, so mail to them is not protected by DANE: alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com, alt4.aspmx.l.google.com.
