I use Google Mail, just with my own domain (via Google Apps). It's a painless setup and if anything had happened to my Google account I can host the email anywhere else in seconds. But for now I don't have to worry about setting up VPSs, mail daemons and whatnot...

(Of course I have to keep a backup of all the mail, but that's as easy as having some client download it.)

Way to go! At Cozy cloud(https://www.cozycloud.cc/) we are developing an open source personal cloud platform that you can self-host and assign your own domain. Right now we already offer backup of your email address but we would like to offer a good web-mail alternative. Have you got suggestion for a Node.js mail client we could cook in?
