Is there any way to get this upgraded feature in the current 4.0 
alpha version?  These are the results of the standard SPF client:

        result = 'pass' / 'fail' / 'error' / 'softfail' / 'neutral' /
                 'none' / 'unknown'
 
   Example headers generated by mybox.example.org:

       Received-SPF: pass (mybox.example.org: domain of
                           myname@... designates 192.0.2.1 as
                           permitted sender)
                           receiver=mybox.example.org;
                           client-ip=192.0.2.1;
                           envelope-from=<myname@example.com>;
                           helo=foo.example.com;

       Received-SPF: fail (mybox.example.org: domain of
                           myname@example.com does not designate
                           192.0.2.1 as permitted sender)
                           receiver=mybox.example.org;
                           client-ip=192.0.2.1;
                           envelope-from=<myname@...>;
                           helo=foo.example.com;

       Received-SPF: softfail (mybox.example.org: domain of
                               transitioning myname@... does 
not
                               designate 192.0.2.1 as permitted 
sender)

       Received-SPF: neutral (mybox.example.org: 192.0.2.1 is neither
                              permitted nor denied by domain of
                              myname@...)

       Received-SPF: none (mybox.example.org: myname@... does
                           not designated permitted sender hosts)

       Received-SPF: unknown -extension:foo (mybox.example.org: 
domain
                                             of myname@example.com 
uses
                                             mechanism not 
recognized by
                                             this client)

       Received-SPF: error (mybox.example.org: error in processing
                            during lookup of myname@...: DNS
                            timeout)

   SPF clients may append zero or more of the following key-value-
pairs
   at their discretion:

      receiver       the hostname of the SPF client
      client-ip      the IP address of the SMTP client
      envelope-from  the envelope sender address
      helo           the hostname given in the HELO or EHLO command
      mechanism      the mechanism that matched (if no mechanisms
                     matched, substitute the word "default".)
      problem        if an error was returned, details about the 
error
