But, I have the idea. It is Exim (as our MTA) that add the Return-path.
my MTA is exim@debian/lenny via smarthost I would say that my emails are sent with Return-Path... but you are able to check yourself :-)
We can't check how you sent your mail, we can just see how it arrived:
Return-path: dev-bounces@lists.roundcube.net

So it's not that easy as you think.
Exim rewrites the header, and it does it by design (for whatever reason) to write it to "Return-path:".
