This needs to be *immediately* followed by what you stated way down

Otherwise it can cause serious confusion with new/inexperienced users.
And this is one of the big reasons I recommend folks put everything
under smtpd_recipient_restrictions.

I don't have the thread archived (it's been 8 years or so), so I'm
guessing here, but IIRC it took at least a half dozen or more emails
back-forth before I understood this lack or inheritance.  Once I did,
and realized how much I'd have to duplicate among the sections, I
switched to EURR (everything under recipient restrictions).
