you misunderstand what SPF is for.  SPF is *NOT* an anti-spam system. it
is an anti-forgery system.

That's what I've always thought it to be. The only role it seems to play in spam-blocking is that it should make RBL's more effective.

complaining that SPF doesn't block spam is like complaining that
jelly doesn't cut through steel.
  

Well, maybe a better analogy might be that a knife-sharpener doesn't cut through steak. It just makes the *knife* cut the steak better.
