EmailRelay is a free and open-source software for email filtering and relaying. In this tutorial, we will learn how to install EmailRelay on Void Linux.

Prerequisites

• A computer with Void Linux installed
• An internet connection

Step 1: Install Dependencies

Before installing EmailRelay, we need to install its dependencies. In the terminal, type the following command:

sudo xbps-install gcc make openssl-devel

This command will install the necessary dependencies for EmailRelay.

Step 2: Download EmailRelay

The next step is to download EmailRelay from its official website. Open your browser and go to https://emailrelay.sourceforge.net/. Click on the "Download" button to download the latest version.

Alternatively, you can download it through the terminal by typing:

wget https://downloads.sourceforge.net/project/emailrelay/emailrelay/2.2/emailrelay-2.2-src.tar.gz

Step 3: Extract and Install EmailRelay

After downloading, extract the downloaded file by typing the following command in the terminal:

tar -xzvf emailrelay-2.2-src.tar.gz

Change the directory to the extracted folder:

cd emailrelay-2.2

Now, we need to compile and install EmailRelay. Type the following commands in the terminal:

./configure
make
sudo make install

This will compile and install EmailRelay on your Void Linux system.

Step 4: Configure EmailRelay

To configure EmailRelay, we need to create a configuration file. Type the following command in the terminal:

sudo nano /etc/emailrelay.conf

This will create a configuration file and open it in the nano editor. Copy and paste the following code into the configuration file:

# Listen on all interfaces
listen-address = 0.0.0.0

# Port to listen on
listen-port = 8025

# Relay all email to the given server
relay-to = smtp.example.com:25

# Use STARTTLS when relaying
relay-to-starttls = yes

# Use AUTH LOGIN when relaying
#relay-to-auth = login

# Username and password for relaying
#relay-to-username = username
#relay-to-password = password

Replace "smtp.example.com" with your SMTP server's domain name or IP address. You can also uncomment and modify the optional settings according to your requirements.

Save the configuration file by pressing "Ctrl+X", then "Y", and "Enter".

Step 5: Start EmailRelay

Finally, it's time to start EmailRelay. Type the following command in the terminal:

sudo emailrelay --daemonize

This will start EmailRelay in the background as a daemon.

Conclusion

Congratulations! You have successfully installed EmailRelay on Void Linux. Now, you can use EmailRelay to filter and relay your emails to the desired SMTP server.
