Installing Mailcow on Fedora Server

Mailcow is a free and open-source email server software that allows you to host your email on your own server. In this tutorial, we will explain how to install Mailcow on the latest version of Fedora Server.

Prerequisites

Before you start, you need a fresh installation of Fedora Server. You also need to have root access to the server.

Step 1: Install Git and Docker

The first thing you need to do is install Git and Docker on your server. You can do that by running the following commands:

$ sudo dnf install git
$ sudo dnf install docker

Once the installation is complete, start and enable the Docker service using systemctl:

$ sudo systemctl start docker
$ sudo systemctl enable docker

Step 2: Clone the Mailcow Repository

Now you need to clone the Mailcow repository by running the following command:

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

Step 3: Configure the Mailcow Environment

After cloning the mailcow-dockerized repository, navigate to the cloned directory:

$ cd mailcow-dockerized

Next, run the following command to copy the sample environment variables files:

$ cp env.example .env

Open the .env file using your preferred text editor and edit the settings to match your requirements. The variables you need to set include the COMPOSE_PROJECT_NAME, MAILCOW_HOSTNAME, SYS_HOSTNAME, MYSQL_ROOT_PASSWORD, REDIS_PASSWORD, and TZ.

Step 4: Generate SSL Certificates

Now you need to generate SSL certificates for your Mailcow server. To do that, run the following command:

$ sudo ./generate-ssl.sh

Follow the on-screen instructions to generate the certificates.

Step 5: Start Mailcow

You can now start Mailcow by running the following command:

$ sudo docker-compose up -d

This will start all the Mailcow services in the background.

Step 6: Access Mailcow Web Interface

Once the installation is complete, you can access the Mailcow web interface using the following URL:

https://<your-server-ip>/admin/

Log in using the username a and the password moohoo.

That's it! You have successfully installed Mailcow on your Fedora Server.
