| # | Protocol | Finding | Severity | Fix |
|---|---|---|---|---|
| 1 | DKIM | Not Detected | High | Ensure your email provider has published DKIM keys. If using a custom selector, DKIM may still be active. |
| 2 | MTA-STS | Not Configured | High | Publish an MTA-STS TXT record and host a policy file at https://mta-sts.yourdomain/.well-known/mta-sts.txt. |
| 3 | TLS-RPT | Not Configured | High | Publish a TLS-RPT record to receive reports when sending servers fail to establish encrypted connections. |
| 4 | BIMI | Not Found | High | Publish a BIMI record with your brand SVG logo. Requires DMARC at p=quarantine or p=reject with pct=100. |
