What Is an SPF Record?
One of the DNS resource records is TXT. It is mostly used to denote facts about the domain and provide information to outside sources. It’s a must-have for email authentication. For example, an email comes from a server to your internet service provider (ISP). ISP can authenticate the email using a dedicated TXT type record, SPF record. This record contains data about the trusted servers authorized by your domain so, your ISP can identify a source an email is coming from and detect a forged email. SPF or Sender Policy Framework is a primary (but not the only) way to authenticate your email.
