✦ Why It Matters
Consider implementing email rules with clear status indicators to enhance user experience in email management.
Key Takeaways
How It Works
Email authentication protocols like SPF, DKIM, and DMARC verify the legitimacy of email senders. SPF checks if a server is authorized to send emails for a domain, while DKIM allows the original sender to sign messages cryptographically.
DMARC ties these checks to the visible sender address, ensuring that messages are not spoofed. Forwarding emails can disrupt these checks, leading to delivery failures.
