स्थानीय होस्ट जीमेल के बजाय

Question

इसलिए का उपयोग कर, मैं javamail और glassfish के माध्यम से ई-मेल भेजने के लिए कोशिश कर रहा हूँ मेल भेजने: यहां मेरे कोड (मैं इसे यहाँ http://www.javasrilankansupport.com/2012/05/send-email-in-java-mail-api-using-gmail.html लगता है)

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(); 
    } 
} 

लेकिन बाद इस समारोह का उपयोग कर रहा है सर्वर पर मैं thos अपवादों को पकड़ने:

के रूप में मैं समझता हूँ, मुख्य समस्या यह है कि ढंग से काम स्थानीय होस्ट और जीमेल के बजाय 25 पोर्ट का उपयोग करना चाहते हैं, और मैं क्यों समझ नहीं सकता। नोट टेलनेट smtp.gmail.com 25, टेलनेट smtp.gmail.com 465 अच्छी तरह से काम करते हैं। कोई सुझाव क्या इसका कारण है?
