| Area | Check | Status | Points |
|---|---|---|---|
| Authentication | SPF and DKIMYes — your mail proves where it comes from. SPF: SPF is managed by a dynamic SPF service, which decides per message; we can’t list its senders from DNS alone. DKIM: Your mail carries a signature inboxes can verify (2048-bit, 1024-bit, 2048-bit, 2048-bit, 2048-bit, 2048-bit). | Pass | 25/25 |
| Anti-spoofing | DMARC enforcementMail that fails your checks is refused. | Pass | 30/30 |
| Delivery | Google, Yahoo and Microsoft sender rulesYes — you meet the published sender requirements. | Pass | 15/15 |
| Encryption | MTA-STSWithout it, an attacker on the network path can downgrade delivery to unencrypted. | Missing | 0/8 |
| Encryption | TLS-RPTAdd a TXT record at _smtp._tls.cnn.com: v=TLSRPTv1; rua=mailto:tls-reports@cnn.com | Missing | 0/4 |
