Hi!

So, I propose rectifying that in SPFv3.  We just need to add a new macro
that expands to the RCPT TO domain of an attempted SMTP transaction.  Might
as well add one for local-part, too.

*Which* RCPT to domain should it expand in this transaction:

  HELO a.first.example.com
  MAIL FROM: <user(_at_)first(_dot_)example(_dot_)com>
  RCPT TO: <user1(_at_)second(_dot_)example(_dot_)com>
  RCPT TO: <user2(_at_)third(_dot_)example(_dot_)com>

(Where the MX records for second and third point to the same machine so
the sending MTA delivers the mail to both recipients in the same
transaction...)

Kind regards,

Hannah.
