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.
