Best I can tell, these are all headers generated by the listserv and
your own receiving service. The headers I was looking for are from the
sender's servers and incoming into the list, but the way the messages
are processed, it's not a re-send, so those don't get copied or
forwarded. Someone with more technical expertise can explain it better,
but, essentially, the message that comes in is stripped, copied and the
content is sent out as a new message rather than merely re-directed, as
is the case with some lists.
