+ * Autodiscover responder
+ ********************************
+ * This PHP script is intended to respond to any request to http(s)://mydomain.com/autodiscover/autodiscover.xml.
+ * If configured properly, it will send a spec-complient autodiscover XML response, pointing mail clients to the
+ * appropriate mail services.
+ * If you use MAPI or ActiveSync, stick with the Autodiscover service your mail server provides for you. But if 
+ * you use POP/IMAP servers, this will provide autoconfiguration to Outlook, Apple Mail and mobile devices.
+ *
+ * To work properly, you'll need to set the service (sub)domains below in the settings section to the correct 
+ * domain names, adjust ports and SSL.
