Hi,

I want to connect to gmail or Yahoo mail server to fetch the new messages. I am trying to connect to gmail using the code below, but I am getting this error:


" javax.mail.MessagingException: Connect failed;
nested exception is:
java.net.ConnectException: Connection timed out: connect
at com.sun.mail.pop3.POP3Store.protocolConnect(POP3St ore.java:161)"

What would be the reason? Can you please suggest ways to handle it?

   public class TestMail{
 
    public static void main(String[] args)
    {
    	String user="xxx";
                String passwd="yyy";
    	new TestMail().receive(user,passwd);
    }
    
  
    public void receive(String username,String password) 

{
        String host = "pop3.gmail.com";
        try {
            Properties prop = new Properties();
            prop.setProperty("mail.pop3.socketFactory.class", 
                                        "javax.net.ssl.SSLSocketFactory");
            prop.setProperty("mail.pop3.socketFactory.fallback", "false");
            prop.setProperty("mail.pop3.port", "995");
            prop.setProperty("mail.pop3.socketFactory.port", "995");
           
            prop.put("mail.pop3.host", host);
            prop.put("mail.store.protocol", "pop3");
            Session session = Session.getDefaultInstance(prop);
            Store store = session.getStore();
            System.out.println("your ID is : "+ username);
            System.out.println("Connecting...");
            store.connect(host, username, password);
            System.out.println("Connected...");
            Folder inbox = store.getDefaultFolder().getFolder("INBOX");
            inbox.open(Folder.READ_ONLY);
 
            Message[] msg = inbox.getMessages();
            
            BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
 
            for (int i = 0; i < msg.length; i++) {
              System.out.println("Subject:" + msg[i].getSubject());
               System.out.println("Read message? [Y to read / N to end]");
              String line = reader.readLine();
              if ("Y".equalsIgnoreCase(line))
              {
                handleMultipart(msg[i]);
                System.out.println("****************************");
              }
              else if ("N".equalsIgnoreCase(line))
               {
                break;
              }
              else
              {}
            }
            if (inbox != null) {
                inbox.close(true);
            }
            if (store != null) {
                store.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

      private void handle(Message msg) throws Exception {
        System.out.println("From:" + msg.getFrom()[0].toString());
        System.out.println("SentDate:" + msg.getSentDate());
    }

              String line = areader.readLine();
              if ("Y".equalsIgnoreCase(line))
              {
                saveAttach(part);
              }
              else{}
            } else if(disposition.equals(Part.INLINE)){
                System.out.println(part.getContent());
            } else {}
        }
    }

}

Thank you,

I can't get on either! So I guess we are not the only ones.

See Configuring other mail clients.

Blind stab: That document lists POP3 host as "pop.gmail.com" not "pop3.gmail.com" as in your code.

[vasavi]

If speciy "pop3.gmail.com" as host

The error I get is
"java.net.UnknownHostException"

[Scleros]

if speciy "pop3.gmail.com" as host...

Yes, the correct host is "pop.gmail.com". Your original post's code had "pop3.gmail.com".

Just change this line

Prop.put("mail.store.protocol", "pop3s");

I think the error is due to invalid username and password.
