| It could work if done right.
We have DNS servers that work right.
These things update every 10 minutes or less..
The domain keys could be done in the same manner. One companies creates the keys on a daily basis allowing each domain up to 3 keys. Simply allow access to aging keys and push out the old keys as time passes. Since the keys change on a day by day base it would be hard to forge them if the keys are maintained by a single domain server.
In this manner if someone hacks a key they will only have 3 days to use the key before it no longer works. This 128bit key would be hard to crack day by day and would cost more money to spam than most spammers can handle. After the oldest key ages out all servers should have been caught up on the new authentication keys. This would help insure that the domain sending the key owns a new code about the same time the spammers has hacked it. Even then a central server could handle these much like the DNS servers are handled today.
