If there's a route where SPF results in PASS, but PRA results in less than
PASS, what is he actually doing with this route ?
Actually PRA can easily cause this when someone puts in a record thinking
that it will not be evaluated in RFC822 scope:
marketing.example.com. TXT "v=spf1 -all" ; don't use in RFC821
bounce.marketing.example.com. TXT "v=spf1 a:outbound.example.com -all"
SenderID says v=spf1 can be used as spf2.0/pra,mfrom. So when someone
checks a message
coming from outbound.example.com
RFC821From as bounce.marketing.example.com
RFC822From as marketing.example.com
SPF passes, SenderID PRA fails (no sender or other PRA headers present)
