Where must a legal serve land in four-wall handball?

In four-wall handball, a legal serve must strike the front wall on the fly after the server hits it from within the serving zone. Following the rebound from the front wall, the ball must land on the floor behind the short line. This landing may occur either before or after the ball strikes one of the sidewalls.1

If the ball fails to cross the short line after rebounding from the front wall, it is considered a short ball, which constitutes a fault.1
