Read sent mails using smtp java

I have been trying lot of things from multiple resources like Read Inbox Java2s
and How to get the list of available folders in a mail account using JavaMail
I am sending emails succesfully, but to be sure of mail is sent successfully, i need to read emails from sent items folder Is this possible with smtp? if yes, how?
Currently I am stuck even in connceting with stroe. I am finding no way to pass the steps
Store store = session.getStore(); and store.connect();
I have no idea about imap or pop3. They might not have been even configured at our server, but if smtp does not faicilitate then I am ready to process with those protocols, though I am sending mails using stmp yet. I have tried lot of edits in my following code, but nothing is helping
String host = "mysite.smtp.com";
Properties props = new Properties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", "myport");
props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
String user = "myname";
String password = "mypassword";
return new PasswordAuthentication(user, password);
}
});
Store store = session.getStore(); // had tried writing "imaps" here
store.connect(host, null, null);
//store.connect(); also tried this
Folder inbox = store.getFolder("INBOX"); //actually i need "SENT"
if (inbox == null) {
System.out.println("No INBOX");
System.exit(1);
}
inbox.open(Folder.READ_ONLY);
Message[] messages = inbox.getMessages();
for (int i = 0; i < messages.length; i++) {
System.out.println("Message " + (i + 1));
messages[i].writeTo(System.out);
}
inbox.close(false);
store.close();

You can't use smtp to read email, you need to use imap. pop3 won't help because it only lets you read the Inbox.
Depending on what you mean by "sent successfully", a successful return from the send method will tell you what you want to know.
Note also that depending on the mail server you're using, sent messages don't automatically appear in a "Sent Messages" folder; you might need to copy them their yourself after sending the message. (Gmail does this automatically, but not all other servers do.)
If what you really want to know is that the message was successfully delivered to the destination mail server(s) and all the addresses were valid, that's harder. The JavaMail FAQ has more information.

I know that I am answering late. I encountered quite similar problems while maintaining a software using extensively mail sending functionalities. I finally created a JUnit extension to write integration tests with a SMTP server emulation.
Please have a look to github.com/sleroy/fakesmtp-junit-runner/. By the way it's open-source.

Java Mail: How to Recognize New Mails

When I receive mails, open the inbox, and get the messages; how can I compare them to a previous array of messages, so that I know which of them I have already read?
Properties properties = new Properties();
properties.put("mail.imaps.host", host);
properties.put("mail.imaps.port", "993");
Session emailSession = Session.getDefaultInstance(properties);
//2) create the POP3 store object and connect with the pop server
Store emailStore = emailSession.getStore("imaps");
emailStore.connect(user,pw);
//3) create the folder object and open it
Folder emailFolder = emailStore.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
Message[] messages = emailFolder.getMessages();

How to handle this depends on exactly what your requirements are. For example, will other applications and/or users be accessing the mailbox at the same time as your application? Or does your application have dedicated access to the mailbox?
You can use the SEEN flag to find messages that you haven't already read.
You can also save the IMAP UID for the last message you processed (and the UIDVALIDITY for the folder) to later find messages with larger UIDs. See the UIDFolder interface for details.
(The comments in your code talk about pop, but your code is using imap; if you ever have to use the pop3 protocol the answers are quite different.)

How to read the UNREAD email using java mail api

I am trying to read the UNREAD mails from gmail account. I tried to filter the messages based on the Flags, but it did not work. I printed the Flags sent on each message, but nothing is set on it, because of which I could not filter the messages. I used the keyword Flags.Flag.SEEN to filter the messages.
After googling, I found out that it is something with the email client. For ex, we need to the change the configuration in gmail or any exchange mail server. Can you please tell me on what to change the configuration to read the UNREAD mails?
Also, end of day, I am going to implement the code into one of the smtp exchange servers. Please let me know if there needs a special configuration. So that I can inform the respective team and then implement my change.
// connects to the message store
Store store = session.getStore("pop3");
store.connect(userName, password);
// opens the inbox folder
Folder folderInbox = store.getFolder("INBOX");
System.out.println("unread count - " + folderInbox.getUnreadMessageCount());
folderInbox.open(Folder.READ_WRITE);
// folderInbox.search(new FlagTerm(new Flags(Flags.Flag.RECENT),
// false));
// fetches new messages from server
Message[] arrayMessages = folderInbox.search(new FlagTerm(new Flags(Flags.Flag.RECENT), false));

The POP3 protocol doesn't support any flags. Use IMAP.

See Retrieving all unread emails using javamail with POP3 protocol.
One comment suggests the use of Flags.Flag.SEEN for Gmail. There's another suggestion about changing settings in your test Gmail account.

IMAP for Hotmail equivalent

We need to build a client for Hotmail, which doesn't support IMAP. To my understanding you have to use exchange w/ POP3 but POP3 doesn't support moving mail from one folder to another. We need the features:
be able to read mail without marking it as "read"
be able to delete mail
be able to move mail out of inbox to another folder and mark as read
Any way to get this to work?

Short answer, No.
License the ActiveSync protocol from Microsoft.
There is an Outlook connector for Hotmail. Maybe with a ton of JNI but check the license first.

Update: Outlook now supports IMAP. Hotmail uses the same servers.

You can do everything you need with JavaMail. Here is the API
Here is an example of getting all unread messages from an inbox and marking them as read. Take a look at the folder class (specifically the copyMessages() method) to move messages to a new folder.
import java.util.Properties;
import javax.mail.*;
import javax.mail.search.FlagTerm;
public class Driver {
public static void main(String[] args){
// Create properties (disable security checks on server)
Properties props = new Properties();
// Get session
Session session = Session.getDefaultInstance(props, null);
try{
// Get the store
Store store = session.getStore("pop3");
store.connect("servername", "username", "password");
//connection configuration
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
//get all unread messages in the inbox
FlagTerm ft = new FlagTerm(new Flags(Flags.Flag.SEEN), true);
Message[] messages = folder.search(ft);
for (int i = messages.length -1; i>=0; i--) {
messages[i].setFlag(Flags.Flag.SEEN, true);
}
// Close connection
folder.close(false);
store.close();
}
catch(Exception e){
e.printStackTrace();
}
}

How to get the list of available folders in a mail account using JavaMail

I am using JavaMail API to connect to my personal account. I have list of folders (labels) in my Gmail account which I created + the default folders like Inbox, Drafts etc. How can I list all the available folders (the default and the user created)?
I can access the particular folder using this API: Folder inbox = store.getFolder("Inbox");. Is there any other API to get the list of folders available in a mail account?

Sergey is close, but by default JavaMail's list() does a LIST "" %, which gives you only top-level folders. GMail puts its system folders (All Mail, Drafts, Sent Mail, Spam, Starred, and Trash) under the non-selectable folder [Gmail], so you really need to do a LIST "" * instead. Otherwise, you'll just get back INBOX, [Gmail], and your labels.
Here's some sample code that connects to GMail, fetches the folder list, and prints out the name and message count for each non-\NoSelect folder (i.e. the ones that aren't just hierarchy placeholders, like [Gmail]):
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
try {
Session session = Session.getDefaultInstance(props, null);
javax.mail.Store store = session.getStore("imaps");
store.connect("imap.gmail.com", "<username>#gmail.com", "<password>");
javax.mail.Folder[] folders = store.getDefaultFolder().list("*");
for (javax.mail.Folder folder : folders) {
if ((folder.getType() & javax.mail.Folder.HOLDS_MESSAGES) != 0) {
System.out.println(folder.getFullName() + ": " + folder.getMessageCount());
}
}
} catch (MessagingException e) {
e.printStackTrace();
}

Here is the code that works. This will give you handle to all the Labels. To go deeper in a folder, you may perform folder.list() or you can use store.getDefaultFolder().list("*") to retrieve all the folders and sub-folders as suggested in the other answer.
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect("imap.gmail.com", "YOURMAILID#gmail.com", "UR_P#ZZWRD");
System.out.println(store);
Folder[] f = store.getDefaultFolder().list();
for(Folder fd:f)
System.out.println(">> "+fd.getName());
Output:
>> INBOX
>> Personal
>> Receipts
>> Travel
>> Work
>> [Gmail]
OLD ANSWER
Please note this is not correct, it's rightly pointed in this answer by dkarp
These should do:
http://java.sun.com/products/javamail/javadocs/javax/mail/Store.html#getSharedNamespaces%28%29
http://java.sun.com/products/javamail/javadocs/javax/mail/Store.html#getUserNamespaces%28java.lang.String%29

You can access other folders like this
store.getFolder("[Gmail]/Sent Mail");
store.getFolder("[Gmail]/Drafts");
etc.

How about store.getDefaultFolder().list()? Just a guess, though.

You can try this:
Folder[] folderList = store.getDefaultFolder().list("*");

You can right-click on different buttons on the side panel of your mail box and inspect the names for different folders that are used in different mails.
This works for every email client. The list command works but I felt this makes the process quicker.
