What is the purpose of the Anti-Spoofing Policy?

The purpose of the Anti-Spoofing Policy is to prevent spoofed emails from reaching users. Spoofed emails are messages that appear to be from a legitimate sender but are actually from a malicious source attempting to deceive the recipient. By implementing an Anti-Spoofing Policy, an organization can protect its users from phishing attacks and other forms of email fraud that could compromise sensitive information or disrupt operations. This policy typically leverages various authentication methods, such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance), to verify the authenticity of the sending server and ensure that only legitimate emails are delivered to users' inboxes.

While some other options may involve aspects of email security, they do not accurately represent the primary function of an Anti-Spoofing Policy. For instance, blocking all incoming emails or allowing only verified senders would be overly restrictive and could hinder legitimate communication, and encrypting outgoing messages pertains to securing email content rather than preventing spoofing. Therefore, the focus and effectiveness of the Anti-Spoofing Policy lie in its ability to filter out fake emails before they can cause harm.
