Mail sending exception

Question

Hi All,
I am developing a Contact Us form. The application is giving me the foll. exception
javax.mail.SendFailedException: Sending failed;  nested exception is: javax.mail.MessagingException: Unknown SMTP host: mail.exchange.com;  nested exception is: java.net.UnknownHostException: mail.exchange.com
My code is as follows:
     Properties properties = new Properties();
     String SMTPIPAddress = "smtpipaddress";     
     String SMTPAddress = "smtpaddress";     
     String mailId = "[email protected]";
     Session session;
     Provider p;
     properties = System.getProperties();
     properties.put("SMTPAddress ", "SMTPIPAddress");
     session = Session.getDefaultInstance(properties, null);
     Message message = new MimeMessage(session);
     try{
               message.setFrom(new InternetAddress(mailId));
               message.addRecipient(Message.RecipientType.TO,
               new InternetAddress(mailId));
               message.setSubject("Conference");
               message.setText("Hello");
               Transport.send(message);
     }catch (AddressException ade) {
          wdComponentAPI.getMessageManager().raiseException(ade.toString(),false);
     }catch(MessagingException msge){
          wdComponentAPI.getMessageManager().raiseException("MessagingException "+msge.toString(),true);     
     }catch(Exception e){
          wdComponentAPI.getMessageManager().raiseException("Exception "+e.toString(),true);
Please let me know what is wrong.

Hi Abhijeet,
Thanks for the reply.
I have given the IP address of SMTP address in Java Mail Client in Visual Admin.
However, I am getting the foll. exception
MessagingException javax.mail.SendFailedException: Sending failed;  nested exception is: javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25;  nested exception is: java.net.ConnectException: Connection refused: connect
Has it got something to do with the port being opened for SMTP host.
Please let me know.
Regards
Nikhil
