In this tutorial, we will be installing Postfix which is an open-source mail transfer agent (MTA) from http://www.postfix.org on Arch Linux. Postfix is a flexible and reliable MTA that is widely popular and used around the globe.
Before we begin installing the Postfix MTA, you must have the following:
sudo).Follow the below steps to install Postfix on Arch Linux:
Start by updating the system to ensure all packages are up to date.
To update the system:
sudo pacman -Syu
To install Postfix, run the following command in your terminal:
sudo pacman -S postfix
After installing Postfix, the main configuration file; main.cf is located at /etc/postfix/main.cf directory.
To edit this directory using nano text editor, run the following command:
sudo nano /etc/postfix/main.cf
Next, add the following line to configure the inet_interfaces option:
inet_interfaces = all
This configuration allows the Postfix to listen on all IPv4 and IPv6 addresses.
Then, add the following configuration to set the Internet hostname of your server:
myhostname = your_hostname.example.com
Be sure to replace your_hostname.example.com with your actual hostname.
Finally, you will need to configure the mydestination option by adding the following line:
mydestination = $myhostname, localhost.$myhostname, localhost
Once you are done making the changes, save the file and exit.
After making changes to the configuration, you can restart Postfix by running the following command:
sudo systemctl restart postfix
To test if the server is running successfully, we'll send a test email. Run the following command in the terminal:
echo "Test email from Postfix" | mail -s "Test Postfix" your_email@example.com
Replace your_email@example.com with an email address that you want to send the message.
If you receive the test email successfully, it means that your Postfix mail server is running successfully.
In this tutorial, you learned how to install and configure Postfix on Arch Linux. You can now set up email communication for personal or business purposes using the mail transfer agent.
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!
Alternatively, for the best virtual desktop, try Shells!
