Explanation

SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are the two foundational industry-standard email authentication protocols. SPF publishes a DNS TXT record listing all servers authorized to send mail for your domain, allowing receiving servers to reject spoofed messages. DKIM cryptographically signs outbound messages so recipients can verify the signature was created by your domain's private key, confirming message integrity and origin. Together they form the basis of a layered authentication strategy (often completed with DMARC). Option A (quarantine) is a filtering action, not an authentication protocol. Option B (blocking all unknown senders) is too aggressive and not an authentication standard. Option D (disabling IMAP) limits email client access but does not authenticate email.
