# What is SPF? # What is SPF?
DANE is short for "**D**NS-based **A**uthentication of **N**amed **E**ntities" and is described in [RFC 6698](https://tools.ietf.org/html/rfc6698). It offers the option to use the DNSSEC infrastructure to store and sign keys and certificates that are used by TLS. So basically DANE can be used to validate provided certificates based on information (a TLSA signature) published in the DNS zone of a specific domain. SPF is short for "**S**ender **P**olicy **F**ramework" and is described in [RFC 7208](https://tools.ietf.org/html/rfc7208). It offers domain owners that use their domains for sending e-mail, the possibility to use the DNSSEC infrastructure to publish which hosts (mail servers) are authorized to use their domain names in the "MAIL FROM" and "HELO" identities. So basically SPF is a whitelist which lists all servers that are allowed to send e-mail on behalf of a specific domain. The receiving mail server may use the information (a SPF record) published in the DNS zone of a specific mail sending domain.
