Using JavaMail to connect to IMAP getting “A1 NO L

问题:

Following is the detail of the server I'm trying to connect

    mailbox_password = KexDa3P7hEtru                            
    mailbox_domain = mail.lenderlive.com    
    mailbox_host= corp.lcl  
    mailbox_username = [e-mail]
    server_type = imap
    port = 143

I'm using the following java code to connect to exchange:

    String domain = "mail.lenderlive.com";
    String user= "[e-mail]";
    String password= "KexDa3P7hEtru";
    String serverType = "imap";

    Store store = null;  
    Properties properties = System.getProperties();
    Session session = Session.getDefaultInstance(properties);
    session.setDebug(true);
    store = session.getStore(serverType);
    store.connect(domain, user, password);

Here is the server trace that I have been getting:

Can someone please help and explain what exactly I'm doing wrong?

回答1:

1. You're using a very old version of JavaMail, please upgrade if you can.
2. You might need to enable SSL.
3. You should change Session.getDefaultInstance to Session.getInstance.
4. I hope you didn't really publish your password above. :-)
