Reading Mails in JavaMail API

Hi,
i need to read my inbox from my gmail account.
i have given the following configuration parameters in my program inside a hashtable.
Hashtable hashObj = new Hashtable();
hashObj.put("host","pop.gmail.com");
hashObj.put("user","[email protected]");
hashObj.put("pswd","password");but i am getting the following error::
javax.mail.MessagingException: Connect failed;
nested exception is:

Hello!
Did you already find why you received that exception when trying to connect to pop.gmail.com?
I'm having the same problem. I can ping pop.gmail.com but I can't telnet it using port 995 (as gmail sais) or port 110 (pop3 default port).
I guess it's not a problem of my code, right? I'm using code from the following link:
http://www.java-tips.org/other-api-tips/javamail/connecting-gmail-using-pop3-connection-with-ssl-2.html
Can you please give me some ideas to solve that.
Greetings,
Filipe

Did you find the JavaMail FAQ?
You should talk to your ISP to get the details for connecting to your server.
In this case I suspect your server wants you to make the connection on the
secure port. The FAQ has examples of how to do this for GMail and Yahoo
mail, which work similarly. By changing the host name, these same examples
will likely work for you.

How to setup SMTP server in PC so as to send mails using JavaMail

Hi,
From forums i got it cleared that we can use JavaMail to send emails. I also got two sample codes about getting it done. But in the code its asks address of the host of SMTP server. I dont have any SMTP server. But i am writing a Library Application in which an email must be sent to users automatically when thier books are in overdue.
Where can i get SMTP server to be installed on my PC so that i can use it send mails through Javamail API.
Thanks

Isnt there any way setup SMTP server on own pc?? I just want to send mails in my local area network.

How to read emails using javamail

hello friends
well i am working on a project on phishing for that i had usinf javamail to read out the mails while i open my any email account while i working on the net .

please help me guys i really need help
please reply as soon as possible
thanks

i could not understand your problem exactly.
if you mean you want to check the new messages count: you can simply used
int newMessages = folder.getNewMessageCount();if you are reading mails first time using javamail.
see http://itoday.wordpress.com/2007/04/08/sending-mail-using-javamail-apis/
if you mean something else ... please let me know

How to identify received mail is failure delivery notice mail in javamail?

Hi friends,
My requirement is that i have to identify failure delivery notice mails while receiving mails through javamail api pop3..
Is there anyway to idenity those among normal mails?
luking forward ur replies dudes...

If you search this forum you'll find some examples, including a simple modification
to the msgshow.java demo program to illustrate the basic use. And don't forget
to read the javadocs for the com.sun.mail.dsn package.
The basics are...
Check for a message of type "multipart/report" (isMimeType), fetch the content of
that message (getContent) and cast it to a MultipartReport object, then use the
methods of that object to extract the data and process it however you want.

Problem Sending mails in a loop using JavaMail API

Hello All,
I am sending emails in a loop(one after the other) using JavaMail API,but the problem is, if the first two,three email addresses in the loop are Valid it sends the Email Properly, but if the Fourth or so is Invalid Address it throws an Exception....
"javax.mail.SendFailedException: Sending failed;"
nested exception is:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 450 <[email protected]>:Recipient address rejected: Domain not found......
So if i want to send hundereds of emails and if one of the Emails inbetween is Invalid the process Stops at that point and i could not send the other emails in the Loop......
How Could i Trap the exception thrown and handle it in such a way, so that the loops continues ..
Is there something with the SMTP Server....?
The code which i am using is as follows....
<Code>...
try {
InitialContext ic = new InitialContext();
Session session = (Session) ic.lookup(JNDINames.MAIL_SESSION);
if (Debug.debuggingOn)
session.setDebug(true);
// construct the message
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(eMess.getEmailSender()));
String to = "";
msg.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to, false));
msg.setRecipients(Message.RecipientType.BCC,
InternetAddress.parse(eMess.getEmailReceiver(), false));
msg.setSubject(eMess.getSubject());
msg.setContent(eMess.getHtmlContents(),"text/plain");
msg.saveChanges();
Transport.send(msg);
} catch (Exception e) {
Debug.print("createAndSendMail exception : " + e);
throw new MailerAppException("Failure while sending mail");
</Code>....
Please give me any suggestions regarding it....and guide me accordingly..
Thanks a million in advance...
Regards
Sam

How about something like the code attached here. Be aware it is lifted and edited out of an app we have here so it may require changing to get it to work. If it don't work - don't come asking for help as this is only a rough example of one way of doing it. RTFM - that's how we worked it out!
SH
try {
Transport.send(msg);
// If we get to here then the mail went OK so update all the records in the email as sent
System.out.println("Email sent OK");
catch (MessagingException mex) {
System.out.println("Message error");
Exception ex = mex;
do {
if (ex instanceof SendFailedException) {
if (ex.getMessage().startsWith("Sending failed")) {
// Ignore this message as we want to know the real reason for failure
// If we get an Invalid Address error or a Message partially delivered message process the message
if (ex.getMessage().startsWith("Message partially delivered")
|| ex.getMessage().startsWith("Invalid Addresses")) {
// This message is of interest as we need to process the actual individual addresses
System.out.println(ex.getMessage().substring(0, ex.getMessage().indexOf(";")));
// Now get the addresses from the SendFailedException
SendFailedException sfex = (SendFailedException) ex;
Address[] invalid = sfex.getInvalidAddresses();
if (invalid != null) {
System.out.println("Invalid Addresse(s) found -");
if (invalid.length > 0) {
for (int x = 0; x < invalid.length; x++) {
System.out.println(invalid[x].toString().trim());
Address[] validUnsent = sfex.getValidUnsentAddresses();
if (validUnsent != null) {
System.out.println("Valid Unsent Addresses found -");

Question about using JavaMail API to read the calendar folder...

Hi,
I've made an application that goes to the mail server, fetches all mails in the calendar folder and tells you the meetings you have in a particular day.
I'm using JavaMail API for this. My problem is that the application is very slow because I'm forced to fetch (one by one!) the contents of every message.
My question is: How can Outlook show so fast the mettings you have? Do they have a specific API that allows them to get the right info by only calling certain methods? Is there something similar in Java?
Thaks for your help!
Note: I use method:
folder.fetch(allMessages, fetchProfile);howerver the fetchProfile class does not allow me to specfy that I want to dowload the contents of the message (you only can specify the content_info); specifying all headears does not help me either.

Clarification:
The VI you have posted will work as following:
1) The task will read 2 analog inputs (ai0, ai3).
2) The acquisition starts, oncece digital signal (trigger) is detected on PFI0
3) The sampling rate will be as specified in "rate" control - it is continuous analog input acquisition, which means that after trigger is received (point 2), the board will start to generate hardware clock with frequency you specify as "rate"
4) with each rising edge of that hardware clock, the measurement is taken, and stored into buffer of driver.
5) DAQmx read will try to read "number of samples per channel" number of samples each time is called - and if there is not enough measurement stored in buffer (step 4), then DAQmx read will wait until DAQ card will measure reaquested number of samples (or timeout occurs before requested number of samples has been acquired)
6) DAQmx read will be then called 1000 times - so totaly you will read 1000 * "number of samples per channel" number of samples.
You do not have to be worried about speed of the loop. In fact, if you need to read just 1000 samples, with 1kS/s, then you can remove for loop and you can change measurement mode from continuous to finite samples, and specify number of samples to read to be 1000. You will read them all properly. I recomend you to read User Manual for your DAQ device - lets say M Series User Manual.
I hope it is clear now.

stefo

You might want to use IMAP to read mail from hMail Server, if you keep messages on server. It has a lot more features for managing messages on server.
A lot of POP3 implementations (both client and server side) will automatically delete retrieved messages. I don't know exactly what JavaMail does in that regard, nor of hMailServer, but I do know some mailservers out in the wild will ALWAYS delete mails retrieved with POP3.

Third Party APIs in Java Language which doesnot use JavaMail APIs

Hi Pals,
Is there any third party java mail APIs available which doesnot using Sun JavaMail APIs? The third party would have its own APIs which does not use javax.mail. I have to code in Java Platform so if the APIs are java based its nice and useful to me.....
Thanks & Regards,
Prakash

Hi,
I am using Javamail APIs to send mails. Sometimes Mcafee blocks the mails and its not allowing javax.mail package. Thats why i would like to go for some other third pary which uses their own APIs......What makes you think a third party API would be less prone to interference by McAfee?

Reading Mail through Java Mail using IMAP

When i tried to connect to IMAP server am getting the following error like Ntlm class not found

I searched this clas in the all the jar in the java mail api.Appreciate your earlier help

I assume you're not actually trying to use NTLM authentication.
A bug in JavaMail 1.4.3 can cause failures related to NTLM in some cases, although I don't think
it should show up as the failure you're seeing. To work around, set the session property
"mail.imap.auth.ntlm.disable" to "true".
If that doesn't solve your problem, make sure you don't have more than one set of JavaMail
classes in your CLASSPATH.

Order, Paginate and List emails in JavaMail API

Am able to sendm and retrieve emails in java using JavaMail API but am having a problem. I would like to sort emails by date, subject, sender etc and also display only a subset of emails using pagination.
            Message[] msgs = folder.getMessages();
            FetchProfile fp = new FetchProfile();
            fp.add(FetchProfile.Item.ENVELOPE);
            folder.fetch(msgs, fp);The function folder.getMessages(); can take 2 arguments (from_index,to_index), but this is according to the way mail server will transalate. POP server will arrange by date while IMAP is unordered. I would like to order the mails then fetch the getMessages(from_index,to_index).
Another posible way am seeing is fetching all mesages using getMessages() put them in a temporary storage(eg. vector or list), order them and then fetch only the page i want. But this could be very costly in terms of processing resources, which makes me believe there is a better approach and it seems i cant find it.
Can somenone please advice me on what to do. I will be very greatful.

With POP3 you have no choice but to download the messages and sort them in the client.
The POP3 protocol simply doesn't provide a "sort" option.
With IMAP, some IMAP servers support a "SORT" extension, although JavaMail doesn't
support it yet.

Email without javamail api

Is there any way to send email with java without using the javamail api
regards
fightspam

Try this
import java.net.*;
import java.util.*;
import java.io.*;
public class email
 private static final String host="smtp.smtphost.co.uk";
 private static final String to="[email protected]";
 private static final String subject="autogenerated message";
 static void send(String message)
 try
 System.getProperties().put("mail.host",host);
 URL url = new URL("mailto:" + to);
 URLConnection connection = url.openConnection();
 connection.setDoInput(false);
 connection.setDoOutput(true);
 connection.connect();
 PrintWriter out = new PrintWriter(new OutputStreamWriter(connection.getOutputStream()));
 out.print("From: <"+InetAddress.getLocalHost().getHostName()+">\n");
 out.print("To: "+to+"\n");
 out.print("Subject: "+subject+"\n");
 out.print("\n");
 out.print(message);
 out.close();
 catch (Exception e)
 public static void main(String[] args)
 for(int i=0;i<10;i++)
 send("this is a test message");
}
