| Check | Result | What it means |
|---|---|---|
| MX | Found (2) | The domain is configured to receive email. |
| SPF | Found | The record ends with ~all: mail from servers not listed should be treated as suspicious but accepted (soft fail). |
| DMARC | p=reject | The policy is reject: receivers are asked to reject messages that fail DMARC. Aggregate reports are requested (rua). |
| DKIM | Not found among common selectors | DKIM can only be confirmed with the selector used by the sender, so this does not mean the domain has no DKIM. |
