If you're going to cast doubt on the choice of the envelope sender
address, perhaps you could describe what you think the right choice is.
I should mention that the behavior you describe, where the vacation notice
goes to the list management software which then treats it as a bounce
sounds like the Right Thing to me, both because the vacation notice is
*NOT* going to the person who sent the message to the list and because it
may result in the user being dropped from the list...which may drive
someone to correct the vacation configuration so that it doesn't respond
to list messages!
