From RFC 822:
4.3.1. RETURN-PATH
This field is added by the final transport system that
delivers the message to its recipient. The field is intended
to contain definitive information about the address and route
back to the message's originator.
Note: The "Reply-To" field is added by the originator and
serves to direct replies, whereas the "Return-Path"
field is used to identify a path back to the origina-
tor.
Exim can be made to add a return-path header "by the final transport
system" by setting the option return_path_add on either an appendfile or
a pipe transport. It will normally remove any such headers it receives
in incoming messages; you can prevent this by setting
no_return_path_remove
but then you run the risk of ending up with more than one of them.
[The index entry for Return-path in the manual points to all this
information about Exim.]
