Rummaging a bit I came up with the two comments at the bottom of the post. As I said - this was the first time I read about Nylas. When I see something potentially shiny I tend to react the same way as if I&#x27;d view an Amazon product listing: Scroll down, look at negative reviews..<p>So - the threads below seem to complain that the sync server has no authentication schema whatsoever (seems to be true after skimming GH&#x2F;the link above) and - this is what I&#x27;m really curious about - even claims that you wouldn&#x27;t accept free contributions to implement that.<p>What I&#x27;m trying to ask, I guess:<p>1) Why no authentication for the sync server?<p>2) Are you really against any such contributions, if you don&#x27;t intend to build those yourself?<p>3) Do you have any recipes&#x2F;ideas&#x2F;reports from happy users how you&#x27;d secure the sync-server in its current state, in a &quot;let&#x27;s play&quot; deployment?<p>1: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11061717" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11061717</a>
