The Sender: header has a very specific meaning and you're trying to
subvert it. Exim will fix up a message when it's handling initial
submissions (local invocation, or "control = submission" in an ACL) and
this involves removing an existing Sender: header.
If you can state what the problem is you're trying to work around, that
might get more useful help.
