How to Install Mailcow on Debian Latest

Mailcow is a popular email server that can be installed on Debian Linux operating system. This tutorial will guide you through the steps necessary to install Mailcow on Debian.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• A Debian Linux machine with root access
• Docker installed on the server
• A registered domain name

Step 1: Install Docker

The first step is to install Docker on your Debian system, if you haven't already. You can do this by running the following commands:

# Update the package list
sudo apt-get update

# Install dependencies
sudo apt-get install -y apt-transport-https ca-certificates curl gnupg2 software-properties-common

# Add Docker's GPG key
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -

# Add Docker repository
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"

# Update the package list again
sudo apt-get update

# Install Docker
sudo apt-get install -y docker-ce docker-ce-cli containerd.io

Verify that Docker is installed on your system by running sudo docker version.

Step 2: Clone Mailcow Repository

You will now need to clone the Mailcow repository from GitHub. You can do this by running the following command:

git clone https://github.com/mailcow/mailcow-dockerized.git

This will clone the Mailcow repository to your current directory.

Step 3: Configure Mailcow

Next, you need to configure Mailcow for your domain. Navigate to the cloned repository and open the mailcow.conf file:

cd mailcow-dockerized
cp example.env .env
nano .env

Edit the file according to your requirements. At minimum, you should change the MAILCOW_HOSTNAME variable to your domain name.

Step 4: Start Mailcow

Once you have configured Mailcow, you can start the Mailcow containers by running the following command:

sudo ./mailcow.sh

This command will start all the required Mailcow containers.

Step 5: Access Mailcow

Finally, you can access Mailcow by navigating to https://<your-domain>/admin in your web browser. You will need to accept the security warning and log in with the default credentials:

• Username: admin
• Password: moohoo

You can change the password for the admin user by navigating to "Administration" > "Edit admin users" in the Mailcow admin panel.

Congratulations! You have successfully installed and configured Mailcow on Debian Linux.
