Sender Rewriting Scheme

Sender Rewriting Scheme (or SRS) allows rewriting the sender’s address on e-mail envelopes to bypass SPF¹ blocking and thus improve e-mail deliverability with redirection.

Activation at alwaysdata

To activate it, go to the menu Emails > Addresses > Modify [e-mail address] - ⚙️ > Redirection > Use SRS

Notes

By enabling SRS, the ENVELOPE FROM and HEADER FROM/FROM no longer match. While this allows SPF validation, it will still not validate DMARC. DMARC validation will depend solely on the presence of a valid DKIM.
