SPF was created to prevent spammers from impersonating the sender of email communication. The Sender Policy Framework (SPF) enables the receiving mail server to verify that mail purporting to come from a given domain is sent from an IP address allowed by the domain's administration during delivery. The DNS publishes a list of approved sending hosts and IP addresses for a domain.
