Kite is a webmail designed to look a lot like gmail and to be easily deployable on a single server. It's written in Javascript with Angularjs for the frontend, and in Python 2 for the backend.
This is very much alpha software, but I hope to have something usable in a couple months.
You can see a demo here.
To run it, you'll need to have vagrant installed. When it's done, run the following commands :
vagrant up
vagrant ssh
sudo -s -u kite
cd /home/kite
python app/back/kite/server.py
After this, browse to http://192.168.50.4 . You should be greeted by a login window. Use whatever username/password combination to login.
I can be reached at contact@khamidou.com. It try to do my best to reply to all incoming email, but sometimes it may slip through.
