JavaMail: Could not connect to SMTP host: localhost, port: 25;

[Sundarajan Srinivasan]

This is my simple code to send a mail:

package com.home.MailOperations;

import java.util.*;

import javax.mail.*;

import javax.mail.internet.*;

import javax.activation.*;

public class SendingMailFromCode {

	public static void main(String args[]) throws Exception {

		String host = "localhost";

		String from = "[e-mail]";

		String to = "[e-mail]";

		Properties properties = System.getProperties();

		properties.setProperty("mail.smtp.host", host);

		Session session = Session.getInstance(properties);

		MimeMessage message = new MimeMessage(session);

		message.setFrom(new InternetAddress(from));

		message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

		message.setSubject("hi..!");

		message.setText("Hi ......");

		Transport.send(message);

		System.out.println("Message Send.....");

	}

}

Sometime I face even 404 error. Please do help.

What smtp server do you have set up on your localhost? Is it listening on port 25 or a different one? The netstat command might be useful.

Koen is correct.

If you do not have an email server/relay on localhost then of course it will fail.

You would normally only find those on a server, such as provided by an ISP or internal network group.
