December 25, 2023

Sender Policy Framework (SPF) is a method of email authentication designed to detect fake sender addresses. It allows domain owners to create a policy that defines authorized mail servers. Once the policy is published in the domain's DNS records, the email server can compare the sender's address with the SPF record.
