I've been thinking about making my own email searchable with elasticsearch. The main thing holding me back is security. With elasticsearch listening on localhost:9200, anyone with local access can read all your mail. Even if you would do this on a computer over which you have full control, even a tiny breach would leak all your mails. I realize this tutorial is just meant to get started with elasticsearch and not meant as a tool to make your email searchable. Still would be interesting to take this to the next level.
