To enable basic hosting services and functions on a Plesk-managed server, the Plesk distribution package includes several third-party software applications that are installed along with Plesk. These applications are responsible for providing various hosting services such as DNS, email, FTP, and others.
All software components shipped with Plesk can be installed and updated by means of Plesk Installer. These components are listed in the Release Notes.
You can also install and manage through Plesk many other third-party applications that are not included in the Plesk distribution package. For the complete list of third-party applications currently supported by Plesk, refer to the Release Notes.
This chapter provides detailed descriptions of different external components used for providing hosting services on a Plesk server.
