Email 邮件：com.sun.Mail.smtp.SMTPSendFailedException:530 5.7.1需要身份验证

我正在尝试从我的Java应用程序向任何特定的电子邮件地址发送电子邮件。我正在使用JavaMail API，但不幸的是，我得到了SMTPSendFailedException错误。谁能告诉我哪里出了错。这是我的密码

    Properties properties = new Properties();
    properties.put("mail.smtp.host", "plus.smtp.mail.yahoo.com");
    properties.put("mail.smtp.port", "587");
    properties.put("mail.smtp.starttls.enable", "true");
    properties.put("mail.smtp.user", emailId);
    properties.put("mail.smtp.password", password);

    Session emailSession = Session.getDefaultInstance(properties,
            new Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(emailId,password);
                }
            });
    emailSession.setDebug(true);

    try {
        MimeMessage message = new MimeMessage(emailSession);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
        message.setSubject("Ping");
        message.setText("Hello, this is example of sending email  ");

        // Send message
        Transport.send(message);
        System.out.println("message sent successfully....");

    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }

当我运行此代码时，我得到：

您应该检查并修复这些问题；特别是，您应该去掉验证器并使用。如果无法升级，请将属性

mail.smtp.auth

设置为

“true”

。而且没有

mail.smtp.password

属性，所以不必费心设置它。

• 在JAVA Mail API中，您必须按照JAVA Mail API的文档设置用户名和发件人地址。因此，

• 这两个句子在您的代码中应该是这样的，无论何时 正在使用JAVA Mail API
  properties.put（“mail.smtp.user”，emailId）
  message.setFrom（新的InternetAddress（emailId））

您好，正如您所说，我已经更改了代码，但仍然会出现相同的错误。有没有可能是防火墙阻止了它。因为当我从另一个s运行这个
