Smail uses sendmail, right?  How does smail persuade sendmail to put
different things in the From_ and From: lines?  I never managed to make
sendmail change the From_ line without changing the From: line at the

that was really truly sent to a bang address?

Where do we get a fix to just this problem, without dragging in all the
rest of smail?
