Good question. I am in thinking this problem. After some thoughts, IMHO, for the individual or small team, the only that we want is a email fowarding server. We do not need a full-fledged email server at all. We can just forward the incoming emails into the destination by a tiny work. We can choose the backend email server like Gmail or others. In this kind of mode, we minimize the cost of a home-made email server. However, excepted that several over-killed servers, I have not found a simple/concise implementation of my idea. It is not hard, and may be a little trivial in fact. I am planning to write a Java or Dart powered. But I have not started on this apsect now:) If other NHers know such kind of a simple email forwarding server app, please share it here for us:)
