I tried Purelymail and though I trust the service, Runbox's web interface left much to be desired. I also have mail went to spam with Fastmail that makes me paranoid and always BCC my gmail account for every important email. One thing that I don't like with Microsoft and Google's mail service is the need to create new account to have a custom domain mail.
