JavaMail - 客户端未通过身份验证，无法在 MAIL FROM 期间发送匿名邮件

Question

我正在尝试使用 JavaMail 通过 office365 有效帐户发送电子邮件。但是，我收到相同的异常 '530 5.7.57 SMTP；在 MAIL FROM 期间，客户端未通过身份验证以发送匿名邮件。按照我用于测试的简单代码：

Properties props = new Properties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.host", "smtp.office365.com");
props.put("mail.smtp.port", "587");
props.put("mail.debug", "true");

Session session = Session.getInstance(props, new Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(USER_NAME, USER_PASS);
    }
});

try {
    final Message message = new MimeMessage(session);
    message.setRecipient(Message.RecipientType.TO, new InternetAddress(USER_NAME));
    message.setFrom(new InternetAddress(USER_NAME));
    message.setSubject(subject);
    message.setText(messageContent);
    message.setSentDate(new Date());
    Transport.send(message);
    System.out.println("Send OK");
} catch (final MessagingException ex) {
    System.out.println(ex.getMessage());
}

调试输出如下：

从日志来看，身份验证似乎不起作用，连接端口变为 25 而不是属性中指定的 587。

我也尝试添加其他属性，比如

props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.user", USER_NAME);
props.put("mail.smtp.password", USER_PASS);
props.put("mail.smtp.from", USER_NAME);

任意组合，但没有结果。我也试过使用更新版本的 JavaMail 库，但异常是一样的。我是否缺少邮件帐户的任何配置？还是来自代码？

提前致谢

已编辑：将端口从 587（整数）更改为“587”（字符串）解决了调试端口中的端口问题，但出现相同的客户端身份验证错误

JavaMail 1.3 已经 17 岁了！你在哪里找到它？切换到 current release and then fix all these common JavaMail mistakes.
