Setup Nameservers
Mail-in-a-Box requires you to set up custom nameservers for proper DNS configuration. The typical format for these nameservers is as follows:
ns1.box.yourdomain.com
ns2.box.yourdomain.com
To configure the nameservers, log in to your domain registrar’s DNS control panel and add two A records that point to your server’s IP address. Once these records are added, change the nameservers for your domain to the ones you just created. Here’s a breakdown of the steps:
In your registrar’s DNS settings, create the following A records:
ns1.box.yourdomain.com → your_server_ip
ns2.box.yourdomain.com → your_server_ip
After creating the A records, go to the domain settings and set the nameservers for your domain as:
ns1.box.yourdomain.com ns2.box.yourdomain.com
DNS changes can take some time to propagate, so allow several hours for the changes to fully propagate across the internet.
Properly configuring your nameservers is essential for Mail-in-a-Box to work correctly, as the software handles DNS management for your domain. It is recommended to use tools like dig or online DNS checkers to ensure that the nameservers have been set up correctly.
Change Hostname
Once your domain and nameservers are ready, you need to change your server’s hostname to match your Mail-in-a-Box setup. Use the following command:
hostnamectl set-hostname box.yourdomain.com
This command sets the Fully Qualified Domain Name (FQDN) for your server, which is required for Mail-in-a-Box to function correctly.
Update System Packages
Before you begin the installation process, make sure your system is up to date. Run the following commands:
sudo apt update && sudo apt upgrade -y
This ensures that all system packages are up-to-date, avoiding potential issues during the installation process.
Installing Mail-in-a-Box
Now that your server is prepared, you can install Mail-in-a-Box by running the official setup script:
curl -s https://mailinabox.email/setup.sh | sudo bash
This script will begin the installation process, guiding you through a series of configuration steps.
Configuring Mail-in-a-Box
During the installation, you will be prompted to configure a few key settings:
Enter your primary admin email address (e.g., admin@yourdomain.com).
Confirm the hostname you set earlier (e.g., box.yourdomain.com).
Choose the appropriate timezone for your server.
Set a strong password for the admin panel, and confirm it.
Press “Enter” to proceed through the steps. The installation script will automatically configure the required services and set up your email server.
Once the installation is complete, you can access the Mail-in-a-Box admin panel by visiting https://your-server-ip/admin and login with the credentials you set during the installation process.
From the admin panel, you can manage domains, email accounts, and other settings. Remember to monitor your server regularly and keep it updated to ensure it continues to run smoothly.
