I love this idea, but it feels like lots of the other improvements to the Email system. SPF was introduced in 2003, DomainKeys in 2007, DKIM in 2008, DMARC 2011; all of these things rely on DNS which for some reason makes it hard to implement. DNSSEC most recently has been gaining traction, but languishes at 12% [1]. These things are hard to implement from an operations point of view for existing systems, but many of the domain names out there are not owned by people with an operations team and do not understand how they could reduce their Spam and increase their security. In order for us to use something like DIME/DMTP we need to find a way to better integrate our DNS and Email infrastructure binding them together. If we can ensure that when a Domain name is registered it is mandatory to provide these additional DKIM/SPF/DIME records then we can make progress. But better still a way to keep these records up to date when we can providers.
