I wish more people capable & confident to do so would run their own email services, and provide access to them for their communities (who would hopefully realise the great benefit of having a family domain). That'd help to undermine the current cabal of mostly ill-intentioned email providers out there. Email's too important to trust to a colossal corporation that sees you (and your correspondents!) as a resource to be data-mined. Plus, it really isn't nearly as hard as people make it out to be.
