Question

我目前正在调查James Mail Server并在我的本地计算机上运行实例。我正在尝试使用以下代码发送电子邮件，我将进入下面列出的例外：

public static void send() {
    try {
        String host = "127.0.0.1";

        Properties props = System.getProperties();
        props.put("mail.host", host);
        props.put("mail.transport.protocol", "smtps");
        props.put("mail.smtps.auth", "true");
        props.put("mail.smtps.port", "465");
        props.put("mail.smtps.ssl.trust", host);

        Session mailSession = Session.getInstance(props);
        mailSession.setDebug(true);

        Message msg = new MimeMessage(mailSession);
        msg.setFrom(new InternetAddress(frAddress));
        InternetAddress[] address = { new InternetAddress(toAddress) };
        msg.setRecipients(Message.RecipientType.TO, address);
        msg.setSubject(subject);
        msg.setSentDate(new Date());
        msg.setText(message);

        Transport transport = mailSession.getTransport("smtps");
        transport.connect(host, userName, password);
        transport.sendMessage(msg, msg.getAllRecipients());
        transport.close();
    } catch (Exception ex) {
        ex.printStackTrace(System.err);
    }
}

transport.connect(host, userName, password)

遇到以下异常

我已按照列出的here步骤配置James服务器以SSL启动，并根据步骤添加了虚拟JKS证书。我一直在网上看，但到目前为止，我无法找到解决方案。 Plz帮助。

编辑：

忘记提及，我已成功使用普通SMTP发送邮件，并附带James附带的默认配置。

嗯，看起来詹姆斯没有正确配置。如果您使用telnet在端口465上连接它，您会得到纯文本响应吗？

此外，您还使用了相当旧版本的JavaMail。您可能希望升级到latest version。

使用STARTTLS从localhost发送邮件时无法识别的SSL消息
