Making the server to sign the mails is a good idea, however it wont wook in public free mails like yahoo, hotmail, gmail, etc as they will not be able to identify spammers from non spammers.

Thats a good point, but I think those guys have ways of handling that. When spam is actually sent through their mailservers they can identify large volumes of mail coming from singular users, or the same mail coming from different users, and flag it for intervention...

They may also force people to fill some form [those ugly digits and letters stuff] to check that they are humans, however it will be very annoying to fill it everytime you want to send an email.
