+ * @section CAPI_MESSAGING_EMAIL_MODULE_OVERVIEW Overview
+ *
+ * The @ref CAPI_MESSAGING_EMAIL_MODULE API provides functions that prepare and send email messages. 
+ * This API allows email message creation, setting message properties 
+ * and sending as well setting up to be notified when the email message has been sent.
+ *
+ *
+ * Email, short for electronic mail, is a method of exchanging digital messages.
+ * This API allows you to send email using SMTP. 
+ * Simple Mail Transfer Protocol (SMTP) used for sending email via Internet is described in RFC5321/5322 standards.
+ *
+ * The Email API consists of functions that:
+ * - Set the subject, body and recipients of an email message
+ * - Set the file path for attaching files to an email message
+ * - Send an email message
+ * - Register/unregister a callback function to be called when the sending process is complete,
+ *     whether it is sent successfully or not
+ *
+ * Email sending is asynchronous and the application should not wait for the result.  
+ * Not only may the process be slow (connections to be established and so on), 
+ * but even if the mail server is not available a message send may not be a failure, if there is a spooling mechanism.
+ * Instead, the callback function is used to receive status. In addition, note that once email_send_message() is called, 
+ * the message contents are out of the application's hands.
+ * Even if the message appears not to have finished sending, it can no longer be modified.
