Please help me to construct a recipe which
deletes all the Received: header lines
and add "X-Received: Deleted all the Received headers"
before forwarding.
'man formail':
     -I headerfield
          Same as -i, except that any existing similar fields are
          simply  removed.   If  headerfield  consists  only of a
          field-name, it effectively deletes the field.

| formail -I"Received:" \
          -I"X-Received: Deleted all the Received headers"
