Installing WildDuck on Fedora CoreOS

In this tutorial, we will guide you through the process of installing WildDuck, an open-source mail server, on the latest version of Fedora CoreOS. WildDuck is a modern email server that allows you to send and receive emails securely with advanced spam and virus protection.

Prerequisites

Before we begin with the installation process, we need to make sure that we have the following prerequisites:

A virtual private server with Fedora CoreOS installed
A domain name pointed to the server's IP address
A user account with sudo privileges to execute commands with administrative access
Basic knowledge of the command line and package management in Fedora CoreOS

Step 1: Update the System

The first step is to update your system with the latest packages by running the following command:

sudo dnf update -y

Step 2: Install Required Dependencies

You need to install some dependencies in order to run WildDuck properly. Run the following command to install the necessary packages:

sudo dnf install curl wget python3 python3-pip systemd-devel libcap2-bin -y

Step 3: Install Node.js

WildDuck is built with Node.js, so we need to install it by following the steps below:

Download the latest version of Node.js from the official website:
```
curl -sL https://rpm.nodesource.com/setup_lts.x | sudo bash -
```
Install Node.js by running the following command:
```
sudo dnf install nodejs -y
```

Step 4: Install WildDuck

Now, we need to download and install WildDuck on our server:

Go to the official WildDuck website and download the latest version of the software:
```
wget https://cdn.jsdelivr.net/npm/wildduck/release/wildduck-latest.tar.gz
```
Unpack the downloaded file using the following command:
```
tar -xzf wildduck-latest.tar.gz
```
Navigate to the extracted directory:
```
cd wildduck-latest
```
Install WildDuck by running the following command:
```
sudo ./install.sh
```
You will be prompted with some setup questions. Follow the instructions carefully and provide your domain name, email address, and other details as needed.

Step 5: Configure WildDuck

WildDuck is now installed on your Fedora CoreOS system, but we still need to configure it to work with our domain name and email clients. Follow the steps below to configure WildDuck:

Open the configuration file in your preferred text editor:
```
sudo vim /etc/wildduck/wildduck.toml
```

Edit the following parameters:

[server]
hostname = "yourdomain.com"

[tlspool.default]
source-address = "yourserveripaddress"

[database.mongo]
host = "localhost"
name = "wildduck"

[user_defaults]
email = "[email protected]"
full_name = "Your Name"

Save and close the file.

Step 6: Start WildDuck

Now, we need to start the WildDuck service and enable it to automatically start on system boot:

Start the service by running the following command:
```
sudo systemctl start wildduck
```
Check the status of the service to make sure it's running:
```
sudo systemctl status wildduck
```
Enable the service to start on system boot:
```
sudo systemctl enable wildduck
```

Conclusion

In this tutorial, we have successfully installed and configured WildDuck on the latest version of Fedora CoreOS. You can now use this email server to send and receive emails securely under your own domain name.
