Gandi has added Sender Rewriting Scheme (SRS) support for forwarded emails, which now makes it possible to preserve the authentication settings of forwarded emails

This SRS email authenticating feature is used to improve deliverability by passing the Sender Policy Framework (SPF) when emails are forwarded. Consider the scenario where elvis@domain.com receives an email from support@emailditings.com, originally sent via Mailchimp Servers, and subsequently forwards the email to john@gmail.com. In such cases, Gmail servers may consider elvis@domain.com as the original sender, thus treating the email as spam or spoofed since it uses support@emailditings.com sender details to deliver the email.

Authenticated Received Chain (ARC) or SRS technology is used to preserve authentication for forwarded emails, thus making the Gmail server understand that the original sender was support@emailditings.com and elvis@domain.com was just used to forward the email.

Gandi’s email hosting platform now fully supports the Sender Rewriting Scheme (SRS). This is particularly important because starting February 1, 2024, Gmail and Yahoo will start rejecting forwarded emails that do not pass all the required email authentication rules.
