Error while running a simple java mail application

[Ratheesh Narayanan]

Hi all,

Can anyone help me in this??

While I am running a simple java mail send application I am getting an error saying..

----------------------Error message------------------------------
javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host: 172.16.65.1, port: 80
at javax.mail.Transport.send0(Transport.java:219)
at javax.mail.Transport.send(Transport.java:81)
at SimpleSender.send(SimpleSender.java:41)
at SimpleSender.main(SimpleSender.java:61)
----------------------End of message------------------------------

I have changed the port from default 25 to 80 since my proxy server port number is 80.

The complete source is given below..

//---------------Source for SimpleSender.java--------------------
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public class SimpleSender
{

public static void send(String smtpServer, String to, String from, String subject, String body)
{
try
{
Properties props = System.getProperties();

props.put("mail.smtp.host", smtpServer);
props.put("mail.smtp.port", "80");
Session session = Session.getDefaultInstance(props, null)

Message msg = new MimeMessage(session);

msg.setFrom(new InternetAddress(from));
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse
(to,false));

Transport.send(msg);

System.out.println("Message sent OK.");
}
catch (Exception ex)
{
ex.printStackTrace();
}
}

public static void main(String args[])
{
String smtpServer="172.16.65.1";
String to="[email protected]";
String from="[email protected]";
String subject="hi";
String body="This is just a trail HI...";

send(smtpServer, to, from, subject, body);
}
}
//---------------------End or SimpleSender.java----------------------

javax.mail.MessagingException: Could not connect to SMTP host: 172.16.65.1, port: 80

172.16.65.1 is a private IP adress, your own adress on your lan.
You need the adress of a SMTP Server. Your internet provider should give you this adress or URL. If you don't know, ask your lan administrator.

If your proxy runs on port 80, then it's probably an HTTP proxy, not an SMTP proxy, and of no use to you. Have you tried a direct connection? Make sure you use the correct IP address, as was suggested above.
