Mail senden

Question

so, ich versuche, E-Mail über Java Mail und Glasfischen zu senden: hier ist mein Code (ich es hier http://www.javasrilankansupport.com/2012/05/send-email-in-java-mail-api-using-gmail.html finden)

private Session m_Session; 
private Message m_simpleMessage; 
private InternetAddress m_fromAddress; 
private InternetAddress m_toAddress; 
private Properties m_properties; 
@Override 
public void sendMail(String mail) throws Exception { 
    try { 

     m_properties  = new Properties(); 
     m_properties.put("mail.smtp.host", "smtp.gmail.com"); 
     m_properties.put("mail.smtp.socketFactory.port", "465"); 
     m_properties.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory"); 
     m_properties.put("mail.smtp.auth", "true"); 
     m_properties.put("mail.smtp.port", "465"); 
     m_properties.put("mail.debug", "false"); 
     m_properties.put("mail.smtp.ssl.enable", "true"); 


     m_Session  = Session.getDefaultInstance(m_properties,new Authenticator() { 
      protected PasswordAuthentication getPasswordAuthentication() { 
       return new PasswordAuthentication("user@gmail.com","password"); // username and the password 
      } 

     }); 

     m_simpleMessage = new MimeMessage(m_Session); 

     m_fromAddress = new InternetAddress("user@gmail.com"); 
     m_toAddress  = new InternetAddress(mail); 


     m_simpleMessage.setFrom(m_fromAddress); 
     m_simpleMessage.setRecipient(RecipientType.TO, m_toAddress); 
     m_simpleMessage.setSubject("Test letter"); 
     m_simpleMessage.setContent("Hi, this is test letter.","text/plain"); 

     Transport.send(m_simpleMessage); 

    } catch (MessagingException ex) { 
     ex.printStackTrace(); 
    } 
} 

aber nach der Verwendung dieser Funktion auf Server fangen i Ausnahmen thos:

, wie ich das Hauptproblem zu verstehen, die wollen Funktion localhost und Port 25 statt gmail verwenden, und ich kann nicht verstehen, warum. Beachten Sie telnet smtp.gmail.com 25, telnet smtp.gmail.com 465 funktionieren gut. irgendwelche Vorschläge, was ist die Ursache dafür?
