Hi there, Creator here. That's an excellent question and one that I am trying to address but, honestly, I don't have a full answer for yet. I tend to be biased in terms of freshness since things change so rapidly these days but there are certainly open source projects such as QMail or Bind which certainly aren't fresh but are absolutely stellar. Food for thought. Thank you.
