6) If it can be solved with port 25 filtering this would be great. But
  the technique to do it is there for years. Why is spam still a problem?


I say that people have been unwilling to do it because they didn't
perceive spam to be a serious problem. The recent escalation of spam
traffic might cause them to consider it now.

Of course, both problems suffer from the issue that they are on the
sender side - most people are more concerned about the spam their
network recieves than the spam their network sends, and they fail to
perceive the relationship between the two.


Giving tools to both the sender and the receiver will help more than just one side having them. That's why it looks like to me that both strategies are helpful, and let both sides of the network do something about the abuse.
