Scheme for SMTP forwarding. SPF (and related systems) present a challenge to forwarders, since the envelope sender address might be seen by the destination as a forgery by the forwarding host. Forwarding services must rewrite the envelope sender address, while encapsulating the original sender and preventing relay attacks by spammers. The Sender Rewriting Scheme, or SRS, provides a standard for this rewriting which makes forwarding compatible with these address verification schemes, preserves bounce functionality and is not vulnerable to attacks by spammers.
