Well yes, it could be done with certificates, but it can also be done via some type of "root server" system like DNS uses. A database distributed among many root servers from the registrars is proven.
Look. The DNS is seriously screwed-up enough as it is. Let's not take a bad model and replicate it elsewhere.
Tracking valid servers seems much easier to track rather than blacklisting IP's that are not mail servers at all or are abusive servers.
Sure. Only accept e-mail from white-listed servers. You don't need a complex system to manage that.
IMHO I don't think it would be that horrible of an idea with the right amount of notification and education to state something such as "register your mail servers by this date or risk service interruption".
