JavaMail - Java Mail Authentication failed Exception

Hi,

I used javamail api to send and receive mails from

MS Exchange server.

Send Mail Program :

package com;

import java.util.Date;

import java.util.Properties;

import javax.mail.Address;

import javax.mail.Message;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeBodyPart;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

public class Send {

public static void main (String args[]) {

try{

// Put the name of the mail

server

String host="exchange

server name";

// From address

String from="from

addres";

// To address

String to="to

address";

// Get system properties

Properties props =

System.getProperties();

// Setup mail server

props.put("mail.smtp.host", host);

// Create mail session

Session session =

Session.getDefaultInstance(props,null);

session.setDebug(false);

// Create a message

Message mimeMsg = new

MimeMessage(session);

// Set from Address

Address addressFrom =

new InternetAddress(from);

mimeMsg.setFrom(addressFrom);

// Set to Address

Address addressTo =

new InternetAddress(to);

mimeMsg.addRecipient(Message.RecipientType.TO, addressTo);

//Set subject and message of the

mail

mimeMsg.setSubject("Testing");

mimeMsg.setText("Testing for the Application");

MimeBodyPart

mimebodypart = new MimeBodyPart();

// attach message BODY

MimeMultipart

mimemultipart = new MimeMultipart();

mimemultipart.addBodyPart(mimebodypart);

// Send the mail

Transport.send(mimeMsg);

System.out.println("Mail Sent");

}

}

It works fine.

Fetch Mail Program :

package com;

import java.util.Properties;

import javax.mail.Flags;

import javax.mail.Folder;

import javax.mail.Message;

import javax.mail.Session;

import javax.mail.Store;

public class Receive {

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

{

// Put the name of the mail server

String host = "mail server";

// Get system properties,

Properties props = System.getProperties();

props.put("mail.imap.host", host);

// Setup authentication, get session

Session session = Session.getInstance(new

Properties());

// Get the store, put pop3 if the mail server is pop3

Store store = session.getStore("imap");

// Enter the username and password while connecting

to the store

store.connect(host, "username", "password");

// Get INBOX folder

Folder folder = store.getFolder("inbox");

folder.open(Folder.READ_ONLY);

// Get directory

Message message[] = folder.getMessages();

for (int i=0, n=message.length; i<n; i++) {

System.out.println(i + ":" +

message.getFrom()[0]+ "\t" + message.getSubject() + "\t" + message.getFolder()+

"\t" + message.getContent());

System.out.println("Mail Received Successfully");

}

folder.close(false);

store.close();

}

}

It throws following error:

ERROR MESSAGE :

Exception in thread "main" javax.mail.AuthenticationFailedException:

A required privilege is not held by the client.

at

com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:436)

at javax.mail.Service.connect(Service.java:233)

at javax.mail.Service.connect(Service.java:134)

at com.Receive.main(Receive.java:46)

It worked fine for the past 1.5 months,suddenly throws this error.

Please let me know whther there is any issue with the mail server or

need to handle it from javamail api/fix it.

Thanks for your time,

Saravana
