SPF, DKIM, and DMARC are pivotal email authentication methods. SPF validates authorized sending servers by cross-checking the sender's IP with approved servers in DNS. DKIM adds a digital signature to ensure message integrity and validate the sender's domain using cryptography. Meanwhile, DMARC builds on SPF and DKIM, offering a framework for authentication policies and monitoring. It specifies how servers should handle emails failing SPF or DKIM checks and provides reporting features. Together, they bolster email security by verifying servers, ensuring message integrity, and offering policy-based authentication and monitoring.
