使用Hotmail帐户使用Java发送电子邮件

Question

我正在做一个Web应用程序，用于使用Hotmail帐户发送电子邮件。 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，但是当我在托管服务器上部署应用程序时，出现以下跟踪：

我非常确定帐户凭据正确，但是身份验证失败。 我还必须说，当我尝试执行此操作时，我收到了一封Microsoft电子邮件，其中说有欺诈性尝试启动会话，但是当我在本地执行代码时，我没有收到此电子邮件。 我查看了页面帐户信息和“安全性和特权”部分，看到我最近的活动似乎对尝试发送电子邮件提出了挑战。 在此信息中，设备和平台是未知的，而ip是我托管的。 有什么办法吗？

Answer 1

我只找到了解决我的问题的可能方法。 我已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。 该密码是我在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。
