没有收到来自SMTP服务器的任何响应

Question

我正在尝试通过以下Java代码发送邮件。

today = new Date();
year = this.today.getFullYear();
month = this.today.getMonth();
day = this.today.getDate();
//To go 18 years back
yearsBack18= new Date(this.year - 18, this.month, this.day);

//To go to same day next year
nextYear= new Date(this.year + 1, this.month, this.day);

但是无法发送邮件， 我得到的唯一输出如下：

    Properties props = new Properties();
    props.put("mail.host",mailProperties.get("mail.smtp"));
    props.put("mail.smtp.auth", "true");  
    props.put("mail.smtp.port", "465");
     final PasswordAuthentication pauth;
    pauth = new PasswordAuthentication(""+mailProperties.get("mail.user"),""+mailProperties.get("mail.pwd"));

   class MyAuthenticator extends Authenticator
        {
            public PasswordAuthentication getPasswordAuthentication()
            {
                return pauth;
            }

        }


        Authenticator auth = new MyAuthenticator();
            Session mail = Session.getInstance(props,auth);
        mail.setDebug(true);
            Message msg = new MimeMessage(mail);
            Transport.send(msg);

当尝试使用telnet进行检查时，我得到的响应如屏幕截图所示。

请提出我需要进行的任何纠正。
