The Sender Policy Framework (SPF) is a critical email authentication protocol designed to combat email spoofing and enhance email security. By publishing specific SPF policy records within DNS TXT records, domain owners can define which mail servers—through IP address authorization—are permitted to send emails on their behalf. This domain-based email authentication strategy enables mail servers…
Sender Policy Framework (SPF) is a vital component of modern email security, designed to help protect organizations against email spoofing and phishing attacks.
