If the site is happy with the current situation, why do you say there's
a problem?

For a site where sendmail always does fixups, and where there's not
enough mail for speed to be a problem, and where the users are happy
with how sendmail interprets their messages, why should they change
anything?

If they're _not_ happy, do you seriously believe that they're going to
``not bother'' correcting the situation?

Generating correct messages is a _cooperative_ effort of both sides of
the MUA---the user's side and the ISP's side.

What you're saying is that the ISP's side can't carry the entire burden.
Indeed, some users want to send some rather weird messages. Obviously,
if a user wants something that the ISP can't do, the user has to do it
himself.
