SimpleLogin

Your email address is your online identity. When you use the same email address everywhere, you can be easily tracked. More information on https://simplelogin.io

This README contains instructions on how to self host SimpleLogin.

Once you have your own SimpleLogin instance running, you can change the API URL in SimpleLogin's Chrome/Firefox extension, Android/iOS app to your server.

SimpleLogin roadmap is at https://github.com/simple-login/app/projects/1 and our forum at https://github.com/simple-login/app/discussions, feel free to submit new ideas or vote on features.

Prerequisites

• a Linux server (either a VM or dedicated server). This doc shows the setup for Ubuntu 18.04 LTS but the steps could be adapted for other popular Linux distributions. As most of components run as Docker container and Docker can be a bit heavy, having at least 2 GB of RAM is recommended. The server needs to have the port 25 (email), 80, 443 (for the webapp), 22 (so you can ssh into it) open.

• a domain that you can config the DNS. It could be a sub-domain. In the rest of the doc, let's say it's mydomain.com for the email and app.mydomain.com for SimpleLogin webapp. Please make sure to replace these values by your domain name whenever they appear in the doc. A trick we use is to download this README file on your computer and replace all mydomain.com occurrences by your domain.

Except for the DNS setup that is usually done on your domain registrar interface, all the below steps are to be done on your server. The commands are to run with bash (or any bash-compatible shell like zsh) being the shell. If you use other shells like fish, please make sure to adapt the commands.

Some utility packages

These packages are used to verify the setup. Install them by:

sudo apt update && sudo apt install -y dnsutils

Create a directory to store SimpleLogin data:

mkdir sl
mkdir sl/pgp # to store PGP key
mkdir sl/db # to store database
mkdir sl/upload # to store quarantine emails
