Sending mail through Java

[Yashwant Palkar]

I am using following code to send mail through java application

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

// Send a simple, single part, text/plain e-mail
public class TestEmail {

    public static void main(String[] args) {

        // SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!
        String to = "[e-mail]";
        String from = "[e-mail]";
        // SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!
        String host = "smtp.yourisp.net";

        // Create properties, get Session
        Properties props = new Properties();

        // If using static Transport.send(),
        // need to specify which host to send it to
        props.put("mail.smtp.host", host);
        // To see what is going on behind the scene
        props.put("mail.debug", "true");
        Session session = Session.getInstance(props);

        try {
            // Instantiatee a message
            Message msg = new MimeMessage(session);

            //Set message attributes
            msg.setFrom(new InternetAddress(from));
            InternetAddress[] address = {new InternetAddress(to)};
            msg.setRecipients(Message.RecipientType.TO, address);
            msg.setSubject("Test E-Mail through Java");
            msg.setSentDate(new Date());

            // Set message content
            msg.setText("This is a test of sending a " +
                        "plain text e-mail through Java.\n" +
                        "Here is line 2.");

            //Send the message
            Transport.send(msg);
        }
        catch (MessagingException mex) {
            // Prints all nested (chained) exceptions as well
            mex.printStackTrace();
        }
    }
}//End of class

its giving me an error 530 5.7.1 Client was not authenticated
DEBUG SMTP: got response code 530, with response: 530 5.7.1 Client was not authenticated


Please help me to solve this issue..

Thanks,
Yashwant

Hi Yashwant,

I would sugget you to put java code in Code block.

Go through following link. follow steps mentioned

http://smtp25.blogspot.com/2009/04/530-571-client-was-not-authenticated.html

before that i suggest you to use your mail account credential i.e. smtp username and password.

[Rob Spoor]

Please UseCodeTags next time. I've added them for you this time.

It seems you need to login to use this SMTP server.

Try sending like this, instead of using Transport.send(msg):

msg.saveChanges(); // Transport.send does this for you
Transport transport = session.getTransport("smtp");
transport.connect(host, "yourusername", "yourpassword");
transport.sendMessage(msg, msg.getAllRecipients());
transport.close(); // should go in finally block

[Yashwant Palkar]

msg.saveChanges(); // Transport.send does this for you   
Transport transport = session.getTransport("smtp");   
transport.connect(host, "yourusername", "yourpassword");   
transport.sendMessage(msg, msg.getAllRecipients());   
transport.close(); // should go in finally block  

this methods are not available which API you are using.

[Lester Burnham]

That's the same JavaMail API you're already using. If you're serious about using it, start by working through a thorough tutorial like http://java.sun.com/developer/onlineTraining/JavaMail/contents.html

[Rob Spoor]

JEE.
Message.saveChanges()
Session.getTransport(String)
Service.connect(String, String, String) (Transport extends Service)
Transport.sendMessage(Message, Address[]) (scroll down; the Address[] won't let me create a direct URL) with Message.getAllRecipients()
Service.close()

I am getting this error while using this code.

[Lester Burnham]

We don't know what "this code" is, but jCIFS is not part of JavaMail or JEE, so it must be used by some other component, possibly the "com.sonicsw.mf.framework" stuff. It has in any case nothing to do with JavaMail.

I advise to get the mail part working as a standalone application -like you did at first- before trying to integrate it elsewhere.

[Yashwant Palkar]

I have tried it with simple java code.
still giving same error

This is log I am getting from code.

[Lester Burnham]

Show us the code that performs the authentication; is it being called?

I think that's not correct. I believe that recent versions of JavaMail have attempted to include NTLM authentication, and for that they simply used jCIFS to do the authentication. I don't know whether that resulted in a requirement to include jCIFS as a dependency or whether it was somehow included directly in the mail.jar, I'm just saying this based on answers I remember seeing on other forums which were posted by the author of JavaMail.

[Lester Burnham]

I stand corrected: JavaMail doesn't ship with jCIFS, but it can make use of it for NTLM authentication. That's documented in the NTLMNOTES.txt file in the JavaMail distribution.

[Paul Clapham]

Aha. Thanks for doing the research, Lester.

You could try something like this:

private void sendMail() {
		Properties props = new Properties();
		props.put("mail.transport.protocol", "smtp");
		props.put("mail.smtp.starttls.enable", "true");
		props.put("mail.smtp.host", "smtp.gmail.com");
		props.put("mail.smtp.port", "465");
		props.put("mail.smtp.socketFactory.port", "465");
		props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
		props.put("mail.smtp.socketFactory.fallback", "false");
		props.put("mail.smtp.auth", "true");
		Authenticator auth = new SMTPAuthenticator();
		Session session = Session.getInstance(props, auth);
		Message msg = new MimeMessage(session);
		try {
			msg.setFrom(new InternetAddress("[e-mail]"));
			msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[e-mail]", false));
			msg.setSubject("Test email");
			msg.setText("Test email text");
			msg.setHeader("MyMail", "Mr. Me");
			msg.setSentDate(new Date());
			Transport.send(msg);
		}
		catch(Exception e) {
			log.error("Error sending e-mail. " + e.getMessage());
		}
	}

Where SMTPAuthenticator is defined as:

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class SMTPAuthenticator extends Authenticator {

	protected PasswordAuthentication getPasswordAuthentication() {
		return new PasswordAuthentication("[e-mail]", "userPassword");
	}
}

[Yashwant Palkar]

I tried through Authenticator but getting same error.
