How to Install Haraka on Void Linux

This tutorial will guide you through the steps of installing Haraka, a fast and scalable Node.js email server, on Void Linux.

Prerequisites

Before you begin, make sure you have the following:

A working instance of Void Linux
Node.js installed on your system

Step 1: Install Haraka

First, we need to install Haraka using Node Package Manager (npm).

Open your terminal and run the following command:
```
npm install -g Haraka
```
This will install Haraka globally on your system.
Verify that Haraka has been installed by running the following command:
```
haraka -h
```
This should display a list of available options for configuring and running Haraka.

Step 2: Configure Haraka

Next, we need to configure Haraka to suit our specific requirements. Haraka provides a default configuration file, which we can customize as needed.

Navigate to the Haraka configuration folder:
```
cd /usr/lib/node_modules/Haraka/config
```
Copy the default configuration file into your home directory:
```
cp haraka.ini ~/.haraka
```
Open the configuration file in your favorite text editor:
```
nano ~/.haraka/haraka.ini
```
Make any necessary changes to the configuration file, such as setting the SMTP port or enabling plugins.
Save the changes and exit the text editor.

Step 3: Run Haraka

Finally, we can start Haraka and begin using it as our email server.

Navigate to the Haraka directory:
```
cd /usr/lib/node_modules/Haraka
```
Start Haraka using the following command:
```
haraka -c ~/.haraka
```
This will start the email server using the configuration file we customized earlier.
Test that the email server is running by sending an email to a test address, such as:
```
echo "Subject: test email" | openssl s_client -quiet -connect localhost:25 -starttls smtp
```
If everything is working correctly, the email should be accepted by Haraka and stored in the appropriate mailbox.

Conclusion

That's it! You now have Haraka installed and running on your Void Linux system. By customizing the configuration file and adding plugins, you can tailor Haraka to suit your individual needs as an email server.
