If you know of an MTA package that will add the envelope-sender data to the Received header, or can write a configuration stanza to add to config files to do this in any given MTA, please add a note about it on this page using the "EditText" button below.

• QmailSpfPatch added by Ed Li <zixia@zixia.net>
  Qmail always save envelope-from in Return-Path header, buf if: 1. We must forward mail to another server, and use SpamAssassin in that server(Return-Path may be changed); 2. any poor gay like me: can't make Return-Path work with SPF(with SpamAssassin 3.0.0-r20550); We need this patch .

Actually, the Return-Path is standard now, and I don't see any need to add yet another way to specify the envelope recipient. Go read RFC-2821 section 4.4 where this header is defined as a MUST. – Arik Baratz
