如何使用 smtp.mail.yahoo.com 发送 Java 电子邮件？

Question

我正在尝试从 "smtp.mail.yahoo.com" 发送电子邮件。我尝试使用不同的端口号，如 587、465 等，当我使用 gmail 主机发送时它工作正常。但是当我尝试使用雅虎时，出现以下异常。

package com.java.sample.workouts;

import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.PasswordAuthentication;
import java.util.Properties;

public class JavaSendEmail {

private static final String SMTP_HOST_NAME = "smtp.mail.yahoo.com";
private static final String SMTP_AUTH_USER = "myyahooid@yahoo.com";
private static final String SMTP_AUTH_PWD  = "mypassword";

public static void main(String[] args) throws Exception{
   new JavaSendEmail().test();
}

public void test() throws Exception{
    Properties props = new Properties();
        props.put("mail.smtp.host", SMTP_HOST_NAME);
        props.put("mail.smtp.port", "465");        
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.ssl","true");
        props.put("mail.smtp.auth", "true"); 

        Session session = Session.getInstance(props,
              new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(SMTP_AUTH_USER, SMTP_AUTH_PWD);
                }
              });

    Transport transport = session.getTransport("smtp");

    MimeMessage message = new MimeMessage(session);
    message.setContent("This is a test", "text/plain");
    message.setFrom(new InternetAddress("myyahooid@yahoo.com"));
    message.addRecipient(Message.RecipientType.TO,
         new InternetAddress("myyahooid@yahoo.com"));

    transport.connect();
    transport.sendMessage(message,
        message.getRecipients(Message.RecipientType.TO));
    transport.close();
}

}

但我遇到了以下异常

Exception in thread "main" javax.mail.AuthenticationFailedException: 535 5.7.1 Authentication failed

按照以下步骤在您的 Yahoo 帐户中启用不太安全的应用程序：

转到帐户信息
Select“账户安全”
启用“允许使用安全性较低的应用程序登录”

我刚刚测试了您的代码，它可以正常工作
