spfXio.com makes it easy for you to implement effective SPF, DKIM, and DMARC records using our management platform.  While we may make it easy, we also encourage anyone responsible for domain email security to develop a foundational knowledge of these protocols, there purpose, how they work together, how they are implemented, and how they are verified.  

 

 

SPF Explained

SPF is a protocol defined by the Internet Engineering Task Force (IETF) that provides a facility for Administrative Management Domains to explicitly authorize hosts permitted to send email on their behalf and for a receiving host to verify if a sender is authorized. 

 

DKIM Explained

DKIM is a protocol defined by the Internet Engineering Task Force (IETF) that provides a mechanism for email senders to digitally sign a message and receivers to verify digital signatures.

 

DMARC Explained

DMARC is a protocol defined by the Internet Engineering Task Force (IETF) that provides facilities for email receivers to authenticate email and email senders to both publish authentication policies and collect feedback regarding authentication performance.
