True, but reducing spam from millions to thousands seems like something 
good, no?

Several big ISP's are blocking port 25 now. I believe this will catch.

It limits the amount of junk coming out from their users, and the usage 
of their tubes.

I doubt even 0.001% of dynamic range Cable/DSL users will ever call to 
ask for port 25 to be opened.

This is something ISP's can implement, and it works.
