Bottom line is that the results can be unpredictable because of vary techniques to prevent spam/user-probing (I believe fastmail.fm have such triggers as well?), DNS issues & etc.
As for the mailfrom however, I tried that before contacting the list and it seems to apply only on header_sender and not on sender. By the way, David, I found lots of your writings regarding Exim on the web and I have to say those are more than just useful, so thanks.
