The way I'm planning to solve this is to refactor my HTTP server to also receive SMTP over HTTP and the same for DNS. That way you can write your own storage/homepage for handling all your internet needs running in one process. The biggest problem with selfhosting is spam, and for that I'm going for IP + geolocation so that you can filter things by from where your spam is coming from. If that fails I'm going to have an authorized from address list system and some kind of RAM only this spam might be something... but that will be memory constrained and lost on reboot! Eventally we are going to need hashes provided with each new (unauthorized) mail, it's sad but that is the way humans work.
