Hi guys, I made a tool to hide my personal email by using "email alias". The project is fully open source and packaged as Docker image. The self-hosting instruction is relatively simple, should work on any Linux distribution (thanks to Docker) and the most complex part is maybe DNS setup on your DNS registrar.
The code has been deployed in production since several months now and is stable. It also comes with some niceties like a Chrome/Firefox/Safari extension and (soon) mobile apps.
The github repo is on https://github.com/simple-login/app
Let me know if you have any feedbacks/questions!
