That's what the message says! But... the envelope has a sender's e-mail address and the recipient's e-mail address.  Not the return address.  That's in the message header -- the data!  And in that, the return e-mail domain (from the Reply-To) is blank because there was nothing supplied for reply-to.

Right, and not much help there.
