Error: javax.mail.SendFailedException

Question

Hi all,
I have a requirement to send a mail on click of a button. I have written a simple java code using java mail API. But while running the application i am getting
javax.mail.SendFailedException: Sending failed;  nested exception is: javax.mail.SendFailedException: Invalid Addresses;  nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
If i run the java code as a standalone java application everything is fine. Only in webdynpro application i am getting the above mentioned error.
My question is do we have to configure any settings in the WAS. If so, can somebody give me a detailed answer how to do the configuration.
Thanks and Regards,
Rathna

I stopped the Antivirus service and checked the application but it doesn't help.
Here is the code. But the code is working fine.
// Get system properties
Properties props = new Properties();
// Setup mail server
props.put("mail.pop3.host","myserver");
props.put("mail.pop3.auth","true");
Authentication auth = new Authentication("[email protected]","abcd");
               Session session = Session.getInstance(props,auth);
               Store store = session.getStore("pop3");
               store.connect("myserver","[email protected]","abcd");
               System.out.println("Connected");
               MimeMessage message =  new MimeMessage(session);
               message.setFrom(new InternetAddress("[email protected]"));
               message.addRecipient(javax.mail.Message.RecipientType.TO, new InternetAddress("[email protected]"));
               message.setSubject("Hello JavaMail Attachment");
               // create the message part
               MimeBodyPart messageBodyPart =  new MimeBodyPart();
               //fill message
               messageBodyPart.setText("Hi");
               Multipart multipart = new MimeMultipart();
               multipart.addBodyPart(messageBodyPart);
               // Part two is attachment
               messageBodyPart = new MimeBodyPart();
               String fileAttachment="D:\Message.txt";
               DataSource source =  new FileDataSource(fileAttachment);
               messageBodyPart.setDataHandler(new DataHandler(source));
               messageBodyPart.setFileName(fileAttachment);
               multipart.addBodyPart(messageBodyPart);
               // Put parts in message
               message.setContent(multipart);
                              // Send the message
               javax.mail.Transport.send(message);
               System.out.println("Mail sent successfully");
               store.close();
