34/8 is notoriously hijacked (in fact, it is probably the largest
network hijacked ever), but in this case 202.56.239.41 is an open
proxy, not an open relay [ http://dsbl.org/listing?ip=202.56.239.41 ],
so there is no reason to believe that the second Received: line
is real.

Also note that 34.148.84.48 is not routed on the Internet at this
point in time:
route-views.oregon-ix.net>sh ip bgp 34.148.84.48
% Network not in table
