Hi, simple question:
at which point adds Postfix the Return-Path header? Which component is doing that? Is it also possible to see this header in a milter? In my tests on a submission connector, I do not get this header. Background to my question: If I really want to do SPF/DKIM/DMARC checks at submission time, I could shoot myself in the feet, if I am not only checking for DMARC, but also having an own domain under DMARC policy. In that case, SPF would always fail. If I read the RFC for SPF correctly, SPF must use the Return-Path.
