OpenSMTPD is a free and open-source implementation of the Simple Mail Transfer Protocol (SMTP) used to send email messages between different servers. It is available for various operating systems including Linux. In this tutorial, we will guide you on how to install OpenSMTPD on your POP! OS Latest.
Before we start the installation process, ensure that you have:
The first step is to update the system packages using the following command:
sudo apt update && sudo apt upgrade -y
This command updates the package list and upgrades installed packages to their latest versions.
After updating the system packages, the next step is to install the OpenSMTPD package using the following command:
sudo apt install opensmtpd
This command downloads the OpenSMTPD package and installs it on your system.
Once the OpenSMTPD is installed, you need to configure it to start automatically when your system boots up. You also need to configure it to allow incoming SMTP connections.
To do that, open the /etc/smtpd/smtpd.conf file using your preferred text editor:
sudo nano /etc/smtpd/smtpd.conf
In this file, specify the following:
Listen on all interfaces:
listen on all
Accept incoming SMTP connections:
accept from any for any relay
Once you have made these changes, save the file and exit your text editor.
After configuring OpenSMTPD, the next step is to start the service using the following command:
sudo systemctl start smtpd
This command starts the OpenSMTPD service.
To ensure that the OpenSMTPD service starts automatically when your system boots up, run the following command:
sudo systemctl enable smtpd
This command enables the OpenSMTPD service.
To verify the installation of OpenSMTPD, you can use the following command to check its status:
sudo systemctl status smtpd
This command will show you whether the service is running, its uptime, and its current status.
Congratulations! You have successfully installed OpenSMTPD on your POP! OS Latest system. By configuring it correctly, you can now send and receive emails between different servers.
