Saving mail into Sent items in JavaMail

Question

I am using something like the following to save a copy of the sent message in the user Sent folder in JavaMail. It works fine for emails with no attachment and for emails whose attachments are less than 1MB. But program stops before the code is actually executed for attachments greater than 1MB. Any idea how to deal with this one?

    String host = ReadConfigPropertiesFile.getPropertyValue("server.host");
        String smtpHost = ReadConfigPropertiesFile.getPropertyValue("smtp.host");
        String from = "[email protected]";
        String to = "[email protected]";
// Get system properties
        Properties properties = System.getProperties();
// Setup smtp mail server
        properties.setProperty(smtpHost, host);
        properties.setProperty("mail.mime.encodeparameters", "true");
        //  properties.setProperty("mail.mime.decodeparameters","true");
        properties.setProperty("mail.mime.encodefilename", "true");
        // properties.setProperty("mail.mime.decodefilename","true");
// Get the default Session object.
        Session session = Session.getDefaultInstance(properties);
// Define message
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO,
                new InternetAddress(to));

        message.setSubject("Peace ", "UTF-8");
// Create the message part
        BodyPart messageBodyPart = new MimeBodyPart();

// Fill the message body
        messageBodyPart.setContent("Hello attachment", "text/html; charset=UTF-8");

        Multipart multipart = new MimeMultipart();
        multipart.addBodyPart(messageBodyPart);

        String[] filename = {"C:/Users/Dake/Desktop/music.mp3"};
        for (int i = 0; i < filename.length; i++) {
            // Part two is attachment
            messageBodyPart = new MimeBodyPart();
            DataSource source = new FileDataSource(filename[i]);
            messageBodyPart.setDataHandler(new DataHandler(source));
            // messageBodyPart.setFileName(filename[i]);
            //messageBodyPart.setHeader("Content-Type", "text/plain; charset=UTF-8; name="+MimeUtility.encodeText(filename[i]));
            // messageBodyPart.setHeader("Content-ID", filename[i]);
            messageBodyPart.setFileName(MimeUtility.encodeText(filename[i], "UTF-8", null)); //encode filename
            //bodyPart.setFileName(MimeUtility.encodeText(attachment.getName(), "UTF-8", null));
            multipart.addBodyPart(messageBodyPart);
        }
        // Put parts in message
        message.setContent(multipart);
        //set the time
        DateFormat df = new SimpleDateFormat("dd/MM/yyyy HH:MM:SS");
        Date date = new Date();
        String sentDate = df.format(date);
        Date dd = (Date) df.parse(sentDate);
        message.setSentDate(date);

        // Send the message
        Transport.send(message);
        System.out.println("Message sent...");
        // Copy message to "Sent Items" folder as read
        Store store = session.getStore("imap");
        store.connect(host, "user", "userpwd");

        Folder folder = (Folder) store.getFolder("Sent");
        if (!folder.exists()) {
            folder.create(Folder.HOLDS_MESSAGES);
        }
        folder.open(Folder.READ_WRITE);
        System.out.println("appending...");
        // folder.appendMessages(new Message[]{message});
        try {

            folder.appendMessages(new Message[]{message});
           // Message[] msgs = folder.getMessages();
            message.setFlag(FLAGS.Flag.RECENT, true);

        } catch (Exception ignore) {
            System.out.println("error processing message " + ignore.getMessage());
        } finally {
            store.close();
           // folder.close(false);
        }

        System.out.println("Msg send and saved ....");
    }

When I run the above code, it displays the appending.... and it stops there forever. And I am using Apache James server 3.0-beta4 as the mail server.

Answer 1

Is your server breaking the connection because it's taking too long to send the message to be appended? (If so, how long is it taking?)

Or is the server breaking the connection because it won't allow you to append a message that large?

Do you get any useful information from the server in the debug output?

Answer 2

I know this is a old question, but maybe this helps you or some others. I guess the problem of your code is that you try to manipulate the Recent-Flag: message.setFlag(FLAGS.Flag.RECENT, true);. According to the IMAP-Standard the Recent-Flag can't be altered by clients.
