Simple Installation of Postfix
Postfix is a popular mail server application that is commonly used on Linux systems. Here are the steps to install Postfix on a Linux system:
- Update the package manager: sudo apt update
- Install Postfix using the following command: sudo apt install postfix
- During the installation process, you will be prompted to select the type of mail server you want to configure. Select “Internet Site” and press Enter.

- Postfix will be installed, and the service will be automatically started.
After installation, you can configure Postfix by editing its configuration file. The main configuration file is located at /etc/postfix/main.cf
. You can use a text editor to modify the settings as per your requirements.
Once you have made any changes to the configuration file, restart the Postfix service using the following command:
sudo systemctl restart postfix
You can also verify that the service is running using the following command:
sudo systemctl status postfix
That’s it! You should now have a working installation of Postfix on your system.
The main.cf

The specific parameters that you should check and configure will depend on your specific use case and requirements. However, some important parameters to consider are:
myhostname

: This parameter should be set to the domain name of your mail server. This can be the same as the FQDN specified inmyhostname
.mydestination

, as well as any other domains that you want to receive mail for.
