Javamail problem with SEEN flags (Autmatically updates the server)

I was getting javax.mail.MessagingException: Unable to load BODYSTRUCTURE error, so I followed the workaround given in the FAQ page http://java.sun.com/products/javamail/FAQ.html#imapserverbug

It says setFlags have no efftect on original message. I am not doing any setFlags in my code. But somehow the server gets updated of this SEEN flag. So once I execute my program all my unread messages in server are set as read irrespective of where I am setting the flag or not.

Pls help me!

Hi,

This is my client which reads the mail. I am using EmailArchitect as mail server.

I had few mails unread before executing this piece of code. But after when I saw the messages in server, they are shown as read.

package com.imap.client;

import java.util.*;

import java.io.*;

import javax.mail.*;

import javax.mail.internet.*;

import javax.mail.search.*;

import javax.activation.*;

public class ReadMail {

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

getMessages();

//getMessages();

}

private static void getMessages() throws IOException {

// SUBSTITUTE YOUR ISP's POP3 SERVER HERE!!!

String host = "mail.com";

// SUBSTITUTE YOUR USERNAME AND PASSWORD TO ACCESS E-MAIL HERE!!!

String user = "user@mail.com";

String password = "password";

// SUBSTITUTE YOUR SUBJECT SUBSTRING TO SEARCH HERE!!!

String subjectSubstringToSearch = "Test E-Mail through Java";

// Get a session. Use a blank Properties object.

Session session = Session.getInstance(new Properties());

try {

// Get a Store object

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

store.connect(host, user, password);

// Get "INBOX"

Folder fldr = store.getFolder("INBOX");

Folder defFldr = store.getDefaultFolder();

fldr = defFldr.getFolder("INBOX");

fldr.open(Folder.READ_ONLY);

int count = fldr.getMessageCount();

System.out.println(count + " total messages");

// Message numebers start at 1

for(int i = 1; i <= count; i++) {

// Get a message by its sequence number

//Message m = (MimeMessage)fldr.getMessage(i);

MimeMessage m = (MimeMessage)fldr.getMessage(i);

MimeMessage mimeMsg = new MimeMessage(m);

}

// "true" actually deletes flagged messages from folder

fldr.close(true);

store.close();

}

catch (MessagingException mex) {

// Prints all nested (chained) exceptions as well

mex.printStackTrace();

}

} //End of class

Thanks,

Rama

You are right, those two lines of code are not requried.

I found that this piece of code makes the message as read automatically.

MimeMessage mimeMsg = new MimeMessage(m);

Is there any way out to avoid this problem? I don't want to make the message as read unless & until the message has been read from my client or actually read.

Thanks!

Sounds like you have a significantly broken IMAP server.

Try switching to a better IMAP server and see if that solves

your problem.

If a mailbox opened read-only is allowing permanent flags

to be changed, that's a serious bug. You can try resetting

the flag yourself, but who knows whether your buggy server

will allow you to do that.
