# SPF

Abbreviation of Sender Policy Framework. Like DKIM, it is a validation system that protects e-mail recipients from spam. Unlike [DKIM](https://www.bartvisions.cz/en/slovnikovy-pojem/dkim-2/), SPF only validates the sender’s address. Server administrators can use SPF to tell which computers in a given domain can send e-mail. The SPF implementation consists of three parts:

- **publishing policy,**
- **control and use of SPF records,**
- **review of forwarded mail.**

Compared to DKIM, this is a more outdated and more demanding method of spam protection, but it still has its place.
