To enable basic hosting services and functions on a Panel-managed server, the Panel distribution package includes several third-party software applications that are installed along with Parallels Plesk Panel. These applications are responsible for providing various hosting services such as DNS, e-mail, FTP, and others.
All software components shipped with Panel can be installed and updated by means of Parallels Installer. These components are listed at http://download1.parallels.com/Plesk/PP10/10.3.0/release-notes/parallels-plesk-panel-10.3.0-for-linux-based-os.html#4.
You can also install and manage through Parallels Plesk Panel many other third-party applications that are not included in the Parallels Plesk Panel distribution package. For the complete list of third-party applications currently supported by Panel, refer to http://download1.parallels.com/Plesk/PP10/10.3.0/release-notes/parallels-plesk-panel-10.3.0-for-linux-based-os.html#5.
