py311-spf-engine

SPF engine for Postfix policy server and milter implemented in Python

This project provides the SPF (Sender Policy Framework) back-end for both pypolicyd-spf (for which it was originally developed) and an future SPF milter using pymilter. The goal is to provide a common back-end for common features for support SPF integration with Postfix and Sendmail using both the Postfix policy service and the Sendmail milter protocol (also available with Postfix).
