Re: [spf-discuss] SPFv1 cleanup

I think 1 important spfv1 cleanup idea is to warn strongly about sender-id's

mis-appropriation of spfv1 records and syntax
and thus a good spfv1 implementating domain should avoid this via say a minimum 
of


example.com v=spf1 redirect=_spf1.%{o}
            spf2.0/mfrom redirect=_spfm2.%{o}
            spf2.0/pra redirect=_spfp2.%{o}

and having the actual spf1 record under

_spf1     v=spf1 {details}
_spfm2    spf2.0/mfrom (same details)

and i a pra {sender-id} believer use it or if just a SPF believer have

_spfp2    spf2.0/pra ?all 


{i personally do a combo like this but use a redirect=%{l}._spf1.%{o} for all 
so each user can personalize their use/non-use -all/~all/?all themselves}
all non-existent envelopes get a v=spf1 -all or spf2.0/mfrom,pra -all
and some special cases like mailer-deamon@ have a spf2.0/pra ?all but a v=spf1 
-all or spf2.0/mfrom -all
as they never are used in envelope
