Incidentally, that's somewhat what I've been building since my recent submission: Show HN: A personal Gmail. (<a href="https://news.ycombinator.com/item?id=4804690" rel="nofollow">https://news.ycombinator.com/item?id=4804690</a>)<p>I learned a lot from HN about trust and got a lot of great feedback via email.<p>Basically, I currently manage my own email via a native app I build with TideSDK and AngularJS. MailGun catches the emails and my rails service drops them into my dropbox as JSON files.<p>There is some magic going on regarding conversation views, labels, attachments, etc.<p>Sadly, I came across a critical memory leak in TideSDK, which currently prevents me from releasing the app/service to the public.<p>Feel free to drop me a message if you're interested in updates.
