Sender Policy Framework (SPF)

The Sender Policy Framework (SPF) is an authentication method which, in combination with DMARC, is used to prevent email spoofing. Email spoofing is used to mislead the recipient into thinking an email is from a different sender, usually a sender that the user will trust. It is a malicious practice often used in phishing and email spam.
