The benefit is pretty obvious. If my IP address and identity
information appears in a Received: header field, then I can't send
mail to a public mailing list without revealing to the world
geolocation information that could be used for doxxing/swatting me,
or for various other nefarious activities, and I can't send email to
an individual unless I am willing to reveal that information to that
individual. And I can't send email through any server operated by
anyone to whom I do not wish to reveal that information.
I remember that years ago (but no longer) there was a remailer server
somewhere in Europe that handled most of this situation. You sent it
your message (with routing info in the message body) and it stripped
off the identification info and headers and sent it to the desired
destination using a new identity. All replies (and other messages to
that identity) went back to the server which then repackaged the
message and sent it back to you.
Of course you had to trust the remailer's operator and accept the
fact that you were talking to it might be an exposure.
