Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during the delivery of the email. SPF alone, though, is limited only to detect a forged sender claimed in the envelope of the email which is used when the mail gets bounced. Only in combination with DMARC can it be used to detect the forging of the visible sender in emails, a technique often used in phishing and email spam.
Email authentication, or validation, is a collection of techniques aimed at providing verifiable information about the origin of email messages by validating the domain ownership of any message transfer agents (MTA) who participated in transferring and possibly modifying a message.
Email spoofing is the creation of email messages with a forged sender address.
