Received: headers and the circumstances in which they are added are
defined by RFC 5321 and its predecessors. They are to be added at the
beginning of the headers by servers that relay the message. The
implication is that the agent that generates the message (Mailman in
this case) should not be including a Received: header in the generated
message, but you could do it.
The attached patch is an example of how this could be done. Note that
the Received: header is inserted at the front of the msg._headers list
rather than setting it in the normal way which would add it at the end.
