Error implementing Java Mail

Question

I downloaded the Javamail package extension and placed the mail.jar file in my WEB-INF/lib directory. Then I reloaded the application and did a restart. I am getting the following error message.
com.sun.mail.smtp.SMTPSendFailedException: 550 bosauthsmtp12: Host 207.119.46.38: No unauthenticated relaying permitted
Any help would be appreciated.
Thanks,
Julie Hall

I am still having problems after reading the information. The mail is being called by a jsp program. I've taken most of the code from a book on JSP's. Here is the code inside my jsp file.
<div id="MainLayer" style="padding-left:10px;padding-right:10px; overflow:hidden; height:100%"> <!-- InstanceBeginEditable name="Main" -->
<%@ page import="java.util.*" %>
<%@ page import="java.io.*" %>
<%@ page import="javax.mail.*" %>
<%@ page import="javax.mail.internet.*" %>
<%@ page import="javax.activation.*" %>
<jsp:useBean id="inn" scope="request" class="bnbTexas.Inn"/>
<jsp:setProperty name="inn" property="*" />
<%
     String host="mail.csites2go.com";
     String to = "[email protected]";
     String from = inn.getEmail();
     String messageText= "Test of email";
     boolean sessionDebug=true;
     Properties props = System.getProperties();
     props.put("mail.host", host);
     props.put("mail.transport.protocol", "smtp");
     Session mailSession= Session.getDefaultInstance(props, null);
     mailSession.setDebug(sessionDebug);
     try
     Message msg = new MimeMessage(mailSession);
     if (from != null)
          msg.setFrom(new InternetAddress(from));
     else
          msg.setFrom();
     InternetAddress[] address = {new InternetAddress(to)};
     msg.setRecipients(Message.RecipientType.TO, address);
     msg.setSubject("bnb Directory");
     msg.setSentDate(Calendar.getInstance().getTime());
     msg.setText(messageText);
     Transport.send(msg);
     catch (MessagingException mex) {
     mex.printStackTrace();
     out.println("mail was sent to " +to);
     out.println(" from " + from);
     out.println(" using host " host ".");
     %>
<!-- InstanceEndEditable --></div>
</div>
Do I need to put the username and password in the properties list before getting a session??
