    These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:Corp.Dmarc_RUA@disney.com (needs natgeotv.com._report._dmarc.disney.com); mailto:Corp.Dmarc_RUF@disney.com (needs natgeotv.com._report._dmarc.disney.com).

Checks

  • ✓ Keys found: mail, selector1 #7
    DKIM keys found for this domain with selectors: mail, selector1
  • !
    Unreadable DKIM key
    These keys could not be parsed, so signatures made with them will fail: mail (RSA public key could not be parsed).
    #23
  • !
    Key in test mode
    These keys have t=y, so receivers treat DKIM failures as a test: mail. Remove t=y once DKIM works.

DANE (TLSA records)

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.
    #32
  • i
    Not configured
    TLS-RPT lets senders report TLS delivery problems to you. It is most useful together with MTA-STS or DANE.
    #35
  • i
    Not used
    No MX host publishes TLSA records. DANE lets senders verify your mail server's certificate through DNSSEC; it requires DNSSEC on the MX host's zone.

Checks

  • i
    Not configured
    BIMI shows your logo next to your mail in supporting mail clients. It requires DMARC enforcement.
