| 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 | Not found | No DMARC policy tells receivers how to handle messages that fail authentication. |
| 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. |
