Question

以下是使用SSL连接POP3的代码。

public void pop3 ()throws Exception{

    // connect to my pop3 inbox
    String a = "javax.net.ssl.SSLSocketFactory";
    final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
    Properties props = new Properties();
    props.setProperty("mail.pop3.host" , "myhost");
    props.setProperty("mail.pop3.port" , "myport");
    props.setProperty("mail.pop3.user" , "username");
    // Start SSL connection
    props.setProperty("mail.pop3.ssl.enable", "true");
    props.put("mail.pop3.socketFactory" , "myport");
    props.setProperty("mail.pop3.socketFactory.class" , a );



    Session session = Session.getInstance(props);

    try {

        Store emailStore = session.getStore("pop3s");

        // getting error while connecting 

        emailStore.connect("myhost",port,"username", "password");

        Folder inbox = emailStore.getFolder("Inbox");
        inbox.open(Folder.READ_ONLY);

        // get the list of inbox messages
        Message[] messages = inbox.getMessages();

        if (messages.length == 0) System.out.println("No messages found.");

        for (int i = 0; i < messages.length; i++) {
            // stop after listing ten messages
            if (i > 10) {
                System.exit(0);
                inbox.close(true);
                emailStore.close();
            }

            Log.e("Message " , String.valueOf((i + 1)));
            Log.e("From : " , String.valueOf(messages[i].getFrom()[0]));
            Log.e("Subject : " ,messages[i].getSubject());
            Log.e("Sent Date : " , String.valueOf(messages[i].getSentDate()));

        }

        inbox.close(true);
        emailStore.close();
    } catch (NoSuchProviderException e) {
        e.printStackTrace();
    }
}

每次我收到以下错误：

W / System.err：javax.mail.MessagingException：Connect failed;

W / System.err：嵌套异常是：

W / System.err：java.net.ConnectException：拒绝连接

W / System.err：at

com.sun.mail.pop3.POP3Store.protocolConnect（POP3Store.java:161）

.....

Answer 1

摆脱所有套接字工厂的东西，you don't need it。

您正在设置“pop3”协议的属性，但您正在使用“pop3s”协议。使用“pop3”协议并将mail.pop3.ssl.enable属性设置为true更简单。

Android：POP3Store拒绝连接
