There is no "setting" for this. You have to change the code in
Mailman/Handlers/SendMail.py, but if you do, it will break automated
bounce processing.

RFC 2821 specifies that the envelope header "From" can -- and in some cases MUST -- differ from the "From" in the message itself. There are a variety of headers, such as From, Resent-From, Errors-To, and there are legitimate reasons for all of them to be different.
