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.
For a vacation program, Reply-To: or lacking that From:. You know, like
replying to a message in a MUA. This is not an innovative design.
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
Aw, come on. Any vacation program that sends any response at all to list
mail is terminally broken.
