Most countries with >1 telco needed to mandate phone number portability, because the telcos would not do it voluntarily. I can't see it being fixed for email though. The sanest ways would be to provide a domain per citizen (essentially operating as a registrar) or a centralized email forwarding service, and I don't see any government putting in that sort of effort for a problem most people don't realize they have.
