In this tutorial, we will guide you through the process of installing OpenSMTPD on EndeavourOS.
OpenSMTPD is a mail transfer agent (MTA) that provides an easy-to-use, scalable, and secure email infrastructure for organizations and individuals.
If you're looking to set up your own email server, then OpenSMTPD is a great choice.
Before we start, you need to make sure that you have EndeavourOS installed and running on your system. If not, then you can download the latest version from the official website(https://endeavouros.com/latest-release/).
You also need to have root access to your system.
OpenSMTPD is available in the EndeavourOS package repositories. You can install it using the following command in the terminal:
sudo pacman -S opensmtpd
This will install the latest version of OpenSMTPD on your system.
Once you have installed OpenSMTPD, you need to configure it to work with your email server. The configuration files for OpenSMTPD are located in the /etc/smtpd directory.
By default, OpenSMTPD is configured to use the 127.0.0.1 IP address for incoming and outgoing emails. If you want to receive emails from external sources, then you need to configure OpenSMTPD to listen on your public IP address.
To do this, you need to edit the /etc/smtpd/smtpd.conf configuration file. You can use any text editor of your choice to edit the file. For example, if you prefer using nano, you can use the following command:
sudo nano /etc/smtpd/smtpd.conf
In the configuration file, you need to change the listen on directive to specify your public IP address. For example, if your public IP address is 192.168.1.100, you need to add the following line:
listen on 192.168.1.100 port 25
Save the changes and exit the text editor.
Now that you have configured OpenSMTPD, you can start the service using the following command:
sudo systemctl start smtpd
This will start the OpenSMTPD service and enable it to listen for incoming emails.
To test if OpenSMTPD is working correctly, you can use the telnet command to connect to your server on port 25. For example:
telnet 192.168.1.100 25
If OpenSMTPD is running and configured correctly, you should see a welcome message from the server.
Congratulations! You have successfully installed and configured OpenSMTPD on your EndeavourOS system. You can now use OpenSMTPD as your mail transfer agent to send and receive emails.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
