| Check | Result | What it means |
|---|---|---|
| MX | Not found | Some senders may try to deliver to the domain's A record, but no mail server is explicitly declared. |
| Free email provider | No | Not a free mailbox service like Gmail or Yahoo. |
| SPF | Not found | No SPF record lists the servers allowed to send email for this domain. |
| 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. |
