ARC (Authenticated Received Chain) and SRS (Sender Rewriting Scheme) have become essential to prevent SPF, DKIM, and DMARC failures during email forwarding and mailing-list processing.
In this video, I explain why forwarding breaks SPF, how SRS automatically rewrites the MAIL FROM to prevent failures, and how ARC preserves message authenticity even after intermediate servers modify the email.

👉 In this video you’ll learn:
• Why forwarding breaks SPF, DKIM, and DMARC
• How SRS rewrites the MAIL FROM to prevent SPF failures
• How ARC guarantees the original authentication chain
• Impacts on reputation, spam, and deliverability
• Why modern email servers must implement ARC + SRS
• 2025 best practices for reliable email deliverability

🎯 Goal: Understand why ARC & SRS are now essential to maintain trustworthy email authentication.
