java - 如何通过 JavaMail 从 Yahoo 服务器发送电子邮件？

Question

我一直试图找到一个更新到最新版本的 JavaMail 的网站，但每当我尝试时，我都会遇到这个烦人的错误(已启用调试)
求助？

代码:

String smtpHost = "smtp.mail.yahoo.com";
        String popHost = "pop.mail.yahoo.com";
        String from = "classified@yahoo.com";
        String to = "classified@yahoo.com";
        String username = "classified";
        String password = "secret";

        // Get system properties
        Properties props = System.getProperties();

        // Setup mail server
        props.put("mail.smtp.host", smtpHost);
        props.put("mail.smtp.port", 587);

        // Get session
        Session session = Session.getDefaultInstance(props, null);
        session.setDebug(true);

        Store store = session.getStore("pop3");
        store.connect(popHost, username, password);

        // Define message
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO, 
          new InternetAddress(to));
        message.setSubject("Hello JavaMail");
        message.setText("Welcome to Yahoo's JavaMail");

        // Send message
        Transport.send(message);

如果你们有有效的代码，可以发布吗？谢谢

您有高级帐户吗？

Or is it a Yahoo problem?

Moved to the appropriate forum, but some versions of yahoo (specifically yahoo.com) do not support POP3 access to mail unless you have signed up for a premium account or have a partner service (like AT&T/Yahoo). When it says "Access is not permitted", that's probably what it means - you don't have a premium account.

[AUTH] Access to this service is not permitted
