Installing Mail-in-a-Box on EndeavourOS

Mail-in-a-Box is a self-hosted email server, which enables its users to install and configure their own email server, complete with webmail, contact list, and calendar. This tutorial will guide you through the process of installing Mail-in-a-Box on EndeavourOS.

Prerequisites

  • A VPS or dedicated server running EndeavourOS latest version.
  • A registered domain name.
  • SSH access to the server.
  • A non-root user with sudo privileges.

Step 1: Update Your Server

The first step is to make sure that your server is up-to-date. Connect to your server via SSH, and update the system packages by running the following command:

sudo pacman -Syu

Once the update is complete, proceed to the next step.

Step 2: Set up SSH Key

To improve security in your system, we can add security by allowing users to log in using their SSH public key instead of passwords. However, enabling the password is also fine in solving this issue.

Step 3: Install Mail-in-a-Box

The next step is to download and install Mail-in-a-Box. To do this, run the following two commands:

curl -s https://mailinabox.email/setup.sh | sudo bash

The above command downloads Mail-in-a-Box installation script, and install all necessary software and packages needed to run the email server.

Step 4: Install DNS

Mail-in-a-Box requires DNS to resolve domain names. By default, Mail-in-a-Box will automatically set up BIND9 as a DNS server. Next, update your DNS records with your domain registrar to point your domain's nameserver at your new DNS server.

sudo mailinabox/tools/bootstrap-dns.sh

Step 5: Install Ceftbot

Certbot is an easy-to-use automatic client that fetches and deploys SSL/TLS certificates for your email server. Install Certbot on your server to secure your email server.

sudo pacman -S certbot
sudo mailinabox/plugins/certbot/certbot-auto --debug

Once installed, Ceftbot will attempt to automatically configure SSL/TLS for the email server.

Step 6: Customize Mail-in-a-Box

When you access your Mail-in-a-Box server's IP address in your web browser, you'll see the Mail-in-a-Box configuration page. Use this page to adjust your Mail-in-a-Box settings and test your email server to make sure that it is working correctly.

Step 7: Configure Your Email Client

Now it's time to configure your email client to connect to your new email server. Open your email client and follow the settings described on the Mail-in-a-Box web interface.

Congratulations! You have now installed a self-hosted email server using Mail-in-a-Box on Endeavour OS.
