Why are you so much worried about the envelope sender, when it is
usually forged? You are not trying to bounce messages that you didn't
want to receive back to the sender, are you? (that would be bounce-spam).
I'm more worried about "! firstname.lastname@example.org" rewriting the message body,
so I usually do something like "formail -R Sender: X-Master-Sender:"
in master and then "formail -I Sender: -R X-Master-Sender: Sender:" on
the machine where I actually receive the message.
