Sending Email with JSP (unable to send to certain email addresses e.g. hotmail.com, rocketmail.com etc)

Hi,

I found a JSP coding by kheefatt to send email with JSP in this forum.

The coding is as below:

send_mail.jsp
----------------

<%@ page language="java" import="java.sql.*, java.util.ArrayList" %>
<%@ page import="java.util.*, javax.mail.*, javax.mail.internet.*" %>
<html>
<head>
</head>
<body>
<table width="50%" border="0" >
<tr>
<td>
<%
     String emailAdd = request.getParameter("receiver");
     String mailBody = request.getParameter("mailtext");
     boolean mail_error = false;
     String errMsg = "";

     try
     {
          Properties props = new Properties();
          props.put("mail.smtp.host", "127.0.0.1");  //replace 127.0.0.1 with the name u specify in your mail server
          Session s = Session.getInstance(props,null);
          MimeMessage message = new MimeMessage(s);
          InternetAddress from = new InternetAddress(emailAdd);
          message.setFrom(from);
          InternetAddress to = new InternetAddress("kheefatt@yahoo.com"); //your email address
          message.addRecipient(Message.RecipientType.TO, to);
          message.setSubject("Mail Test!");
          message.setText(mailBody);
          Transport.send(message);
     }
     catch (Exception ex)
     {
          String titleMsg = "Error Exception";
          errMsg = ex.getMessage();
          mail_error = true;
     }    
     if (mail_error==false)
          out.write("Thank you for subscribing to our newsletter.<BR>");
     else if (mail_error==true)
     {
          out.write("There's an error in the mail server. Please try again later!<BR>\n");
     }
%>
</td>
</tr>
</table>
</body>
</html>


I replace the 127.0.0.1 in props.put("mail.smtp.host", "127.0.0.1") with the address I usually put in the SMTP serve section of my Outlook Express (mail.mycompany.com). I was able to sent to all mycompany.com accounts (i.e xxx@mycompany.com) but was unable to send other account such as xxx@hotmail. What did I do wrong?
FYI, the mail server is provided by the hosting company. We rented a webspace with a hosting company, and the package include email accounts.

in JavaMail API you can set username and password for SMTP authentication.
Check following code http://www.javacommerce.com/articles/SendMailUsingAuthentication.java

you probably need to putr the IP address with the port
i.e.
props.put("mail.smtp.host", "127.0.0.1:8080")

I think it is sent to the junk mail folder. Check your junk mail folder and see.

It is impossible it works on all your mycompany.com accounts but not to hotmail. Try to disable your junk mail filter and try again. Good luck!

There is nothing wrong with hotmail. There is actualy error in the program when I try to sent to hotmail.

Here is the error message:

hi kheefatt,

I found out that I have to put in my username and password in order to send outside our own company account. How can I do that?

Can u show me the code?

thanks

I think u haf the application did wrongly. U dont need to put in any username and password in order to send a mail through a mail server. U download a free smtp mail server and try it out on yur local pc first.
props.put("mail.smtp.host", "127.0.0.1") <-- u put in the IP or the name of the mail server, not your email account.

This is what my colleague told me. She did a similar program before and she also face the same problem until still put in username and password (I can't use her codes because it's very different from mine). My hosting company purposely set their servers to require authentication to sent mail. This is to prevent spamming.
