I think you are confused about what Return-Path is for but, regardless,
email to this mailing list contains a Return-Path generated by the
ezmlm/qmail software that manages this mailing list.

It looks something like:

Return-Path: cygwin-return-148528-...

Private email will have a path which reflects the actual sender.

And, from rfc2821 (there may be later ones also):

	The primary purpose of the Return-path is to designate the address to
	which messages indicating non-delivery or other mail system failures
	are to be sent.

i.e., the Return-Path shouldn't be used as the address for a mail client to
respond to.
