Comment (by tigertech):

 I want to second the comment from LynxChaus: This proposed change is a bad
 idea that will cause some systems to discard the mail.

 RFC 2821 section 4.4 says: "A message-originating SMTP system SHOULD NOT
 send a message that already contains a Return-path header". If WordPress
 submits messages that include a "Return-Path" header via a SMTP system
 that enforces this rule, the message will not be delivered.

 Please don't do this. It will break things.
