   String result;
   String to = 
"[email protected]"
;
   String from = 
"[email protected]"
;
   String host = 
"localhost"
;
   Properties properties = System.getProperties();
   properties.setProperty(
"mail.smtp.host"
, host);
   Session mailSession = Session.getDefaultInstance(properties);
   
try
{
      MimeMessage message = 
new
 MimeMessage(mailSession);
      message.setFrom(
new
 InternetAddress(from));
      message.addRecipient(Message.RecipientType.TO,
new
 InternetAddress(to));
      message.setSubject(
"This is the Subject Line!"
);
      message.setText(
"This is actual message"
);
      Transport.send(message);
      result = 
"Sent message successfully...."
;
   }
catch
 (MessagingException mex) {
      mex.printStackTrace();
      result = 
"Error: unable to send message...."
;
   }
%>
<html>
<body>

<p align=
