The [Sender Policy Framework (SPF)](/docs/mta/authentication/spf) helps mail servers verify whether an email claiming to come from your domain was sent from an authorized server. SPF records are published as TXT records.

```
TXT mail.example.org. v=spf1 a ra=postmaster -all
TXT example.org. v=spf1 mx ra=postmaster -all
TXT mail.example.org. v=spf1 a -all
TXT example.org. v=spf1 mx -all
```

These policies indicate that mail can be sent from the server defined by the domain’s MX or A records, and instruct recipient servers to reject emails from unauthorized sources.
