SRS (Sender Rewriting Scheme) is a protocol used to fix issues caused by SPF (Sender Policy Framework) when forwarding emails .
- The Problem: When an email is forwarded, the receiving server sees Hostaday as the sender, but the SPF record belongs to the original sender, causing the email to fail security checks.
- The Solution: SRS rewrites the sender's address for the forwarded message so it passes SPF validation. This ensures that forwarded emails reach your inbox instead of being rejected or marked as spam .
