As I read his post, indeed he does.  He wants legitimate posters to be
told they need to sign up for the list before they can post.  It's
true that you can supply a reason for an MTA rejection, but (in my
experience) it is unfortunately also true that many originating MTAs
are not configured to report that reason.  Others will substitute a
stock text for the numerical code (especially in cases of
internationalization).  The most reliable way to give those legitimate
users full information is for Mailman to create and send a bounce
mail.

Because of the specific issue with Yahoo, he "deeply regrets that we
must make a special exception for Yahoo."

When implementing that policy exception for Yahoo, it would make sense
to do so at the MTA level, as you suggest, if his MTA provides the
hooks and he can write the needed glue code.  (It's a bit much to call
that exercise "configuration", IMO.)
