OpenSMTPD is a free, secure, and easy-to-use SMTP implementation that supports modern internet standards. In this tutorial, we will guide you through the process of installing OpenSMTPD on Manjaro Linux.
Before you start the installation process, make sure that you have the following prerequisites:
We recommend you to update your system packages before installing any new software to ensure that you have the latest updates and bug fixes. To do that, run the following command:
sudo pacman -Syu
After the system update, you might need to reboot your system to apply the changes.
To install OpenSMTPD on Manjaro, you need to use the pacman package manager. Open your terminal and run the following command to install OpenSMTPD:
sudo pacman -S opensmtpd
During the installation process, you may see several prompts that ask you to confirm your installation. Type y and hit Enter to continue.
After the installation process, you need to configure the OpenSMTPD service before you can use it to send and receive emails. The configuration files are located at /etc/smtpd/ directory.
The main configuration file is smtpd.conf that defines the main settings of your SMTP server. You can edit the file using a text editor of your choice. For example, we will use the nano editor:
sudo nano /etc/smtpd/smtpd.conf
The configuration file has a simple syntax based on rules of the form action pattern match { ... }. Each rule consists of three parts:
Here is a basic configuration file that allows all outgoing emails (clients) from the server to be sent to any destination:
listen on lo0
listen on eth0
accept from any for any relay
Once you have made changes to the configuration file, save them and exit the editor.
After the configuration is complete, you need to start the OpenSMTPD service to start sending and receiving emails. To do so, use the following command:
sudo systemctl start smtpd.service
You can check the status of the SMTP server with the following command:
systemctl status smtpd.service
If the installation and configuration are successful, you should see a message indicating that the service is working correctly.
In this tutorial, we have shown you how to install and configure OpenSMTPD on Manjaro Linux. You can now use this secure and reliable email service to send and receive emails on your system.
