If you wish to use a different server to send the e-mail messages, then you must edit the ROOT.xml file located inside your portal installation under conf/Catalina/localhost and register your server there. Editing Settings for Default Plugins Finally, you can configure the defaultpluginsthatwillbeavailabletoyourportalusers. Remember that plugins are basically the portlet applications that the user can install on her pages. Using the Plugins tab, you can configure what portlets, themes, layout templates, and other plugins your portal users are allowed to use depending on their roles. Here, for example, you can determine that power users can access only certain themes and add only certain port- lets to their pages.
