Ok, so then there is no way for Mailman to know the envelope sender,
right?  Mailman can only look at the mail that is piped into it from the
MTA (sendmail in my case), so if the information isn't available on the
headers, Mailman can't be aware of it.

Are we really talking about the 'sender' mail header?
