A Sender: header (besides others) is being added by exim because the From: domain does not
match 'qualify_domain'. (The outgoing messages are sent by authenticated users via submission.)
Now I´m looking at the documentation, trying to figure out how to disable this feature for
such messages:
http://www.exim.org/exim-html-current/doc/html/spec_html/ch-message_processing.html
The documentation seems rather foggy in this regard. Setting 'local_from_suffix' does not help,
and other related options apparently can only be used globally, though the manual indicates that
the feature could somehow be disabled by the ACL.
I´d probably be fine when I manage to disable adding the Sender: header.
