 * @class KEMailClientLauncherJob kemailclientlauncherjob.h <KEMailClientLauncherJob>
 *
 * @brief KEMailClientLauncherJob starts a mail client in order to compose a new mail.
 *
 * It creates a startup notification and finishes it on success or on error (for the taskbar).
 * It also emits an error message if necessary (e.g. "program not found").
 *
 * The job finishes when the application is successfully started.
 * For error handling, either connect to the result() signal, or for a simple messagebox on error,
 * you can do
 * @code
 *    job->setUiDelegate(new KDialogJobUiDelegate(KJobUiDelegate::AutoHandlingEnabled, this));
 * @endcode
 *
 * @since 5.87
