CISSP Questions #2: Sender policy framework. Sender Policy Framework (SPF) is an e-mail validation system designed to prevent e-mail spam by detecting e-mail spoofing, by verifying the sender’s IP address. SPF allows administrators to specify which hosts are allowed to send e-mail from a given domain by creating a specific SPF record in DNS. Mail exchanges use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain’s administrators.
