无法使用 JavaMail 连接到 Hotmail答案

【问题标题】：Can't connect to Hotmail with JavaMail无法使用 JavaMail 连接到 Hotmail
【发布时间】：2015-05-27 03:29:00
【问题描述】：

首先，如果这是一个重复的问题，请允许我申请。在过去的两个日历月中，我一直在尝试使用 JavaMail 发送电子邮件。通过我的 Hotmail 帐户。我已经使用了过去发布到该站点的有关此主题的大量提示和代码片段；但是，当我执行 Transport.connect 方法时，我仍然收到 java.net.ConnectException: Connection denied...

这是我的代码

String fromUserName = "testEmailAddress@hotmail.com";
String fromEMailAddress = "My Email Test <testEmailAddress@hotmail.com>";
String fromEmailPassword = "testEmailPassword";
String emailServerName = "smtp.live.com";
String emailServerPort = "587";
String toEMailAddress = "<TestDestinationEmailAddress@gmail.com>";      

Properties emailProps = System.getProperties();
emailProps.put("mail.smtps.host", emailServerName);
emailProps.put("mail.smtps.auth", "true");
emailProps.put("mail.transport.protocol", "smtps");
emailProps.put("mail.smtps.starttls.enable", "true");
emailProps.put("mail.smtps.ssl.enable","true");
emailProps.put("mail.smtps.port", emailServerPort);
emailProps.put("mail.debug", "true");

Authenticator localAuthenticator = new SMTPAuthenticator(fromUserName, fromEmailPassword);

Session emailSession = Session.getInstance(emailProps, localAuthenticator);

try {

    SMTPTransport emTransport = (SMTPTransport) emailSession.getTransport("smtps"); 
    emTransport.connect(emailServerName, Integer.parseInt(emailServerPort), fromUserName, fromEmailPassword);
    System.out.println("Ok, we connected ok.");

    MimeMessage emailMsg = new MimeMessage(emailSession);           
    emailMsg.addRecipient(Message.RecipientType.TO, new InternetAddress(toEMailAddress));
    emailMsg.setFrom(new InternetAddress(fromEMailAddress));
    emailMsg.setSubject("Automated Notification Number 1");
    emailMsg.setContent(getHtmlContent(), "text/html");
    emTransport.sendMessage(emailMsg, emailMsg.getAllRecipients());
    System.out.println("Sent Message#: 1");

} catch (Exception e) {
    e.printStackTrace();
}

这是一个例外......

DEBUG JavaMail version 1.4.5
DEBUG successfully loaded resource: /META-INF/javamail.default.providers
DEBUG SMTP useEhlo true, useAuth true
DEBUG SMTP trying to connect to host "smtp.live.com", port 587, isSSL true

    at com.acf.TestingClasses.EmailSendingGames.main(Unknown Source)
Caused by: java.net.ConnectException: Connection refused: connect

有几点：

“smtp”和“smtps”我都试过了……好像没关系
我尝试了端口：25、465、587 和 995...仍然拒绝连接
我已经在多台计算机上尝试了代码，结果相同。
从 JavaMail 演示代码中剪切并粘贴代码，但仍然出现错误。
该代码适用于 yahoo、at&t、gmail 和其他...但不适用于 Hotmail！

有人在使用 JavaMail + Hotmail 组合时遇到了一些问题：stackoverflow.com/questions/9086420/…

【解决方案1】：

我删除了所有“socketFactory”的东西，如Using javamail to send from hotmail? 然后它工作正常......

下面是函数：

private Properties _setProperties() {   
    Properties props = new Properties();   

    props.put("mail.smtp.host", _host);   

    if(_debuggable) {   
      props.put("mail.debug", "true");   
    }   

    if(_auth) {   
      props.put("mail.smtp.auth", "true");   
    }

    props.setProperty("mail.transport.protocol", "smtp");
    props.setProperty("mail.host", _host);
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.port", _port);

    return props;
  }

想必你已经读过this JavaMail FAQ entry。

您是否也尝试过调试技巧here？

从您发布的调试输出来看，您似乎有防火墙或阻止您连接到该站点的东西。
