| SPF | Found | The record ends with -all: mail from servers not listed should be rejected (hard fail). |
| DMARC | Invalid record | A record exists at _dmarc, but it does not start with v=DMARC1, so receivers ignore it. |
| 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. |
