As do an increasing number of ISPs and email service providers - AOL and Yahoo have started bouncing mail which attempts to deliver directly to port 25 on their mail servers from known-to-be-residential (dynamically assigned, mostly) IP addresses.
But they can already verify that the IP address is associated with given user (if they want to go to the trouble to do so). Regardless, what is blocking traffic to port 25 from their known customers going to do for them to reduce the risk of their customers sending SPAM?
Oh, I see what you are saying. They are blocking incoming mail addressed to their users/customers not from their customers. Yeah, I guess that could be a problem.
Gee, life was so easy when you just set uunet to be your forwarder of last resort.
