That header isn't always available to the end-user -- some mail systems might strip it off. However, almost all list mail has the list address in either To or Cc (only Bcc-list mail doesn't, and that's pretty rare). These two headers are also visible in every single mail client I can think of, so I'm doubly surprised that the OP's users have such trouble distinguishing list mail. - Adrian
