| Check | Result | What it means |
|---|---|---|
| MX | Found (1) | The domain is configured to receive email. |
| Mail provider | Yahoo | Inferred from the MX host names: they point to Yahoo mail servers. |
| SPF | Found | The record ends with ~all: mail from servers not listed should be treated as suspicious but accepted (soft fail). |
| DMARC | p=quarantine | The policy is quarantine: receivers are asked to treat messages that fail DMARC as suspicious, for example by delivering them to spam. 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. |
