| SPF | Found | The record ends with -all: mail from servers not listed should be rejected (hard fail). |
| DMARC | p=reject | The policy is reject: receivers are asked to reject messages that fail DMARC. |
| 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. |
