While I'll remain neutral about the specifics of SPF (and all the other
solutions), the legacy problem comes up trying to secure any thing.  If 
it (and I deliberately leave "it" undefined) had never worked, no one 
would complain. Of course, there will always be someone who goes too one 
extreme or the other extreme.  People were dropping heavily spoofed 
domains before SPF anyway.

At what point do we consider legacy support not worth it?  It took 10+ 
years, but now almost no SMTP servers allow open relay by default.  Will 
it take another 10+ years to stop supporting misconfigured migratory 
laptops by default?
