Ah, the joys of broken software...
     
In order to pass on the envelope sender value, you'll need to capture 
the current value, then pass the '-f' flag to sendmail to set it on 
the outgoing message:
     
     
     # Use de Morgan's laws to get a shortcircuted 'OR' operation here. 
     :0
     * ! ^Return-Path: *\/[^ ]+
     * ! ^From *\/[^ ]+
     { }
     :0 E
     { ENVFROM = $MATCH }
     
     FROM=`formail -rtxTo:`
     :0
     *^TOawillis
     | formail -i"To:alex_willis(_at_)hphc(_dot_)org" \
     -i"From: $FROM" | $SENDMAIL -f "$ENVFROM" -oi -t
     
     :0
     *^TOwalkman
     | formail -i"To:walkman(_at_)shell4(_dot_)ba(_dot_)best(_dot_)com" \ 
     -i"From: $FROM" | $SENDMAIL -f "$ENVFROM" -oi -t
