At the point where the redirection is done there isn't a
return-path, only an envelope. 2822bis does not and should not
discuss envelope issues - that's for 2821bis.
This is the one thing on which I disagree with Ned. It is perfectly
reasonable to resend post-delivery. In that case, you'll have
Resent-* fields prepended to the message which may already have a
Return-Path. It will get a new Return-Path when it is delivered to
the mailbox in the Resent-To, and that will be the MAIL FROM of the
resender.
Maybe there's an argument for removing a Return-Path before
prepending the Resent-* fields, but that's a different discussion.
