It's not (necessarily) rules and restrictions but protocols that need to change.
So-called standards such as web and mail are wide open to abuse and so far they have only been (badly) patched. A new patch announced today-ish - DMARC - is only the latest patch for mail, for example, and does not address the fundamental protocol security issues. In particular, it does not address the issue of spam being sent by the "top" agencies' webmail sites for such as G, Y, hotmail and AOL.
