[spf-discuss] Received-SPF extensions

2007-02-24 09:01:21
Currently, pymilter adds up to 3 SPF headers:
2007Feb24 10:49:22 [4149] Received-SPF: none (mail.bmsi.com: 212.76.37.164 
is neither permitted nor denied by domain of apachegrips.com) 
client_ip=212.76.37.164; envelope_from="Poratoiyg(_at_)apachegrips(_dot_)com"; 
helo=nat-go2.aster.pl; receiver=mail.bmsi.com; identity=mailfrom
2007Feb24 10:49:22 [4149] X-Hello-SPF: pass
2007Feb24 10:49:22 [4149] X-Guessed-SPF: neutral

The X-Guessed-SPF header exists because such heuristic results should 
always be distinguished from the official SPF result.  The X-Hello-SPF 
header exists because adding two Received-SPF headers is cumbersome and 
redundant (been there, done that).

Now, I'm thinking that X-Hello and X-Guessed should be extended keywords 
on the Received-SPF, so that the above would become:

2007Feb24 10:49:22 [4149] Received-SPF: none (mail.bmsi.com: 212.76.37.164 
  is neither permitted nor denied by domain of apachegrips.com) 
  client_ip=212.76.37.164; 
envelope_from="Poratoiyg(_at_)apachegrips(_dot_)com"; 
  helo=nat-go2.aster.pl; receiver=mail.bmsi.com; identity=mailfrom;
  x-hello=pass; x-guessed=neutral

Comments?  Anyone already using similar keywords that I should be consistent
with?
