Question

我想使用ip地址发送电子邮件

我正在尝试从javacode发送电子邮件，它写在下面

public static void sendEmailReminder(String emailid,String messageTosend ) {

    String to=emailid;//change accordingly
    Properties props = new Properties();
    props.put("mail.smtp.host", "myIp");
    props.put("mail.smtp.socketFactory.port", "25");
    props.put("mail.smtp.port", "25");

      Session session = Session.getDefaultInstance(props,
    new javax.mail.Authenticator() 
    {
          protected PasswordAuthentication getPasswordAuthentication() {
          return new PasswordAuthentication("myId@yahoo.com","mypassword");//change accordingly              
             }
            });

    try {
    MimeMessage message = new MimeMessage(session);
    message.setFrom(new InternetAddress("myID@yahoo.com"));//change accordingly
    message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
    message.setSubject("Registration Details");
    message.setText(messageTosend);
    message.setContent(messageTosend, "text/html");
    Transport.send(message);
    System.out.println("message sent successfully");

    } catch (MessagingException e) {throw new RuntimeException(e);}


}

按照http://www.yuki-onna.co.uk/email/smtp.html 在触发telnet之后，它应该显示输出为

telnet mail.domain.ext 25
Trying ???.???.???.???...
Connected to mail.domain.ext.
Escape character is '^]'.
220 mail.domain.ext ESMTP Sendmail ?version-number?; ?date+time+gmtoffset?

但是当我使用telnet时，我正在关注

home@linux-t0cw:~> telnet myIp 25 
Trying myIp...
Connected to myIp.
Escape character is '^]'.

我没有得到最后一行，即

  220 mail.domain.ext ESMTP Sendmail ?version-number?; ?date+time+gmtoffset?

此外，当我在java代码上运行时，我在控制台中没有得到任何东西，因为它需要花费很多时间连接到ip myIp。

请帮助我对此不熟悉，我不知道错误在哪里。
