I add failed SPF to the spam score which determines if it goes into my 
inbox, possible spam or straight to spamornot for very high stuff. I get a 
few every hour that get caught - some do get a few RBL hits too but SPF will 
show a fail before it gets into the RBLs. I also publish it with "exists" so 
I can go through the DNS logs to see who's might have been trying to send 
mail from my domains.
