How to Install Slimta on Kali Linux Latest

Slimta is a Python-based email server that provides a modern and scalable approach to handling email traffic. This tutorial will guide you through the steps of installing Slimta on Kali Linux latest version.

Prerequisites

Before you begin, make sure you have the following:

• A system running Kali Linux latest version
• Root access or superuser privileges
• Python 3 installed

Step 1 - Install Dependencies

To install Slimta, the first step is to install its dependencies. Open the terminal window and run the following command to install the required packages:

sudo apt-get update
sudo apt-get install build-essential python3-dev python3-pip libssl-dev libcurl4-openssl-dev libxml2-dev libxslt-dev

Step 2 - Install Slimta

Once the dependencies are installed, we can proceed with the installation of Slimta. You can install Slimta by running the following command in your terminal:

sudo pip3 install slimta[postfix,dkim]

This command will install Slimta with the Postfix and DKIM options.

Step 3 - Configure Slimta

After the installation is complete, we need to configure Slimta to work with our email server. For this tutorial, we will be using Postfix as our email server.

Navigate to the Slimta configuration directory by running the following command:

cd /etc/slimta/

In this directory, you will find a file named slimta.conf.example. Make a copy of this file and rename it to slimta.conf:

sudo cp slimta.conf.example slimta.conf

Next, open the slimta.conf file using your text editor of choice:

sudo nano slimta.conf

In this file, you can configure various aspects of Slimta, such as SMTP settings and logging information. For this tutorial, we will only make changes to the Postfix configuration.

Find the [postfix] section of the slimta.conf file and modify the following values:

relay_host = your.mail.server
relay_port = 25
relay_protocol = smtp

Replace your.mail.server with the hostname or IP address of your Postfix server.

Save and close the file.

Step 4 - Start Slimta

After configuring Slimta, we can start it by running the following command in the terminal:

sudo slimta start

This command will start the Slimta service in the background. You can verify that Slimta is running by checking the service status:

sudo slimta status

Conclusion

Congratulations! You have successfully installed and configured Slimta on Kali Linux latest version. You can now use Slimta to handle your email traffic with ease.
