     Your message implies that for some reason you actually care what
is in the Return-Path header line.  You shouldn't.  I can put whatever
I damn well please in there.  If it pleases me to put in the physical
login-id/host-name in there, that's my business not yours.  Any
presumption on your part that there is any relation between the
Return-Path and any other header line (including Sender!) is faulty.

     It can also be argued that your mail reader is faulty for even
presenting the Return-Path information to the user.  Return-Path is
in the header only to assist mail transports which don't have the
concept of out-of-band envelopes.  Since you're on ARPANET, it's
irrelevant.
