Section 3.5 says:

   Address to which notifications       Errors-To:,    Non-standard,
   are to be sent and a request to      Return-        discouraged.
   get delivery notifications.          Receipt-To:
   Internet standards recommend,
   however, the use of RCPT TO and
   Return-Path, not Errors-To, for
   where delivery notifications are
   to be sent.

It should say:

   Address to which notifications       Errors-To:,    Non-standard,
   are to be sent and a request to      Return-        discouraged.
   get delivery notifications.          Receipt-To:
   Internet standards recommend,
   however, the use of MAIL FROM
   and  Return-Path, not Errors-To,
   for where delivery notifications
   are to be sent.

Notes:

Notifications and bounces are delivered to "MAIL FROM" envelope address of original message.
--VERIFIER NOTES--
Return-Path *is* where the MAIL FROM address is put into a message header.
