Please note: Plesk Email Security requires Dovecot and Postfix, shipped as components with Plesk, on a Linux server. The extension works independently from Plesk’s built-in SpamAssassin component. This extension disables the user interface and the rules added by the component if installed! You don’t have to install or uninstall the SpamAssassin component to use Plesk Email Security properly. The Greylisting functionality does not work with Email Security and is disabled in the installation process. The manual learning process is not executed if SELinux Enforcing mode is enabled.
