Paste maillogs;  headers, to some extent, can be faked (though those 
look legit)  

I think the most likely problem is that you have some forwarding going on
(check your .forward files and /etc/aliases to begin with-  if you are using
some new-fangled mail-forward system to be compatable with SPF, I would
look at that first)    Either that or you have something weird where your 
submit daemon and the regular daemon disagree on who is the master.
