Summary



The 'prconfig/initServices/initEmail/default' Dynamic System Setting (DSS) is set to 'false' (Owning Ruleset - Pega-Engine) to disable all the email Listeners on node restart. However, error occurs when executing the out-of-the-box pyStartEmailListener activity to manually start the Listeners after server startup.
