Sender Policy Framework (SPF)
Sender Policy Framework (SPF) is an email authentication method that helps verify a sender’s identity to prevent email spoofing. It works by allowing domain owners to specify which mail servers are authorised to send emails on their behalf.
SPF is a security protocol designed to reduce the risk of email fraud. It operates at the Domain Name System (DNS) level, where domain owners publish SPF records that contain a list of approved IP addresses and servers allowed to send emails from their domain. When an email is received, the receiving mail server checks the SPF record of the sender’s domain. If the email comes from an approved source, it passes SPF authentication; if not, it may be rejected or marked as suspicious.
