java - 使用 Java 使用 hotmail 帐户发送电子邮件

Question

我正在做一个使用 hotmail 帐户发送电子邮件的网络应用程序。这是我的代码:

props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "smtp.live.com");
props.put("mail.smtp.auth", true);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.user", "mail@hotmail.com");
props.put("mail.smtp.pwd", pass);
props.put("mail.debug", true);
props.put("mail.smtp.starttls.enable", "true");

Session session = Session.getDefaultInstance(props);

session.setDebug(true);

try {
    MimeMessage mimeMessage = new MimeMessage(session);
    mimeMessage.setFrom(new InternetAddress("othermail@otherserver.com"));
    mimeMessage.addRecipient(Message.RecipientType.TO, new InternetAddress("mail@hotmail.com"));
    mimeMessage.setSubject(subject);
    mimeMessage.setContent(message, "text/html; charset=UTF-8");
    mimeMessage.setSentDate(new Date());

    SMTPTransport transport = (SMTPTransport) session.getTransport("smtp");
    transport.connect("smtp.live.com", "mail@hotmail.com", pass);
    transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients());
    transport.close();
} catch (MessagingException e) {
    ret = false;}

当我在本地使用此代码时，一切正常，但当我在托管服务器上部署我的应用程序时，出现以下跟踪:

我很确定帐户凭据是正确的，但身份验证失败。另外我不得不说，当我尝试这样做时，我收到一封微软的电子邮件，说有人试图启动 session ，但是当我在本地执行代码时，我没有收到这封电子邮件。我查看了页面帐户信息和安全和隐私部分，看到我最近的 Activity 出现了关于此尝试发送电子邮件的挑战安全性。在此信息中，设备和平台是未知的，IP 是我的主机。有什么办法可以做到这一点？

我只找到了解决我的问题的可能方法。我在帐户中启用了两步验证。启用此选项后，hotmail 会为您提供创建应用程序密码的选项。这个密码是我在我的应用程序中使用的密码，而不是 hotmail 帐户的真实密码。此解决方案也适用于 Gmail 帐户。
