Might this serve just as well - and with less risk: 1) AFAIK, Exim has, or *can extract* the information that was in the 'Received:' header just prior to the one it normally adds. 2) "Received:" headers are ordinarily 'stacked' - latest on top. 3) IF THEN Exim is told to save, then construct and add-back an extra 'Received:' header that is basically a duplicate of what it had on-arrival, that header can be at the top of the stack. Will that 'satisfy' the next level of servers w/o losing the 'real' traceback info? ... and, if so, might that be better than stripping headers?
