of course I can change the From-header, but what I need to change is the
sender-address (not From in the data-part, but MAIL FROM = return-path
in the smtp envelope).

No, example header generated by exim:

Received: from nobody by my.server.de with local (Exim 4.30)
    id 1BxmAr-0003Zp-WE; Thu, 19 Aug 2004 14:37:45 +0200


"nobody" is the linux-user who send the mail, no matter which sender and
from-address he choosed.

It seems that a wrapper script is the easiest way from of this. Just
iterate through arguments, check if there's one beginning with "-f" and
if not, parse the mail-data for a From-lind and set my own -f argument.
