Yes, please.  The spec mentions that checking "can be performed
elsewhere in the mail processing chain", but then it says (twice)

   <ip>   - the IP address of the SMTP client that is emitting the
            mail, either IPv4 or IPv6.

Formally, the client that /is emitting/ the mail is the previous hop,
isn't it?  IMHO, that deserves an errata.

Perhaps the correct wording could be based on a formal definition of
border, along the lines of http://www.openspf.org/Community/Glossary
