What is SPF? Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during email delivery. SPF allows domain owners to specify which mail servers are authorized to send email on behalf of their domain. Receiving mail servers then verify incoming mail against the published SPF records to help prevent email spoofing.
