The Sender Policy Framework (SPF) is a crucial email authentication protocol designed to protect both individuals and organizations from email spoofing and phishing attacks. At the heart of SPF is the SPF record, a specific type of DNS record (typically a TXT record) that acts as an explicit policy for your domain name. This record lists the mail servers or authorized IP addresses that are permitted to send emails on behalf of your domain, providing an essential line of defense against fraudulent use.
