Two questions, both relating to the very first ("Return-Path") line:
 
1.  Who generates this line?  (My guess for the answer is gatekeeper
.cca.rockwell.com .)  Is it done using the information in the RFC-821
"Mail From:" header line?
 
2.  How did the extra "<" (after the "owner-piporg-l") get there?
