Bad idea. It facilitates even more yet breaking of the end-to-end
peer-to-peer Internet as we know it and would likely be applied to
restrictions affecting more than just mail.

Let those that wish to restrict the use of their network enforce their
own restrictions rather than tell others how to do it for them.
How much of a problem are spoofed mail client IP numbers?

Exactly. Bad! <http://www.fourmilab.ch/documents/digital-imprimatur/>
We've been forced to give up on mail, now the rest?
