| MX | Found (5) | The domain is configured to receive email. |
| Mail provider | Inferred from the MX host names: they point to Google mail servers. | |
| 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. |
