Javamail doesn't get all mail - java

I'm trying to get all mails of my gmail but I can only get 250. According to https://javaee.github.io/javamail/FAQ#gmailsettings, I had already set the number of mail limit to 1000 but it still only fetch 250 mails. Here's my code
import java.util.Properties;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.NoSuchProviderException;
import javax.mail.Session;
import javax.mail.Store;
public class Getreply {
public static void check() {
String host = "pop.gmail.com";
String mailStoreType = "pop3";
String username = "";
String password = "";
try {
//create properties field
Properties properties = new Properties();
properties.put("mail.pop3.host", host);
properties.put("mail.pop3.port", "995");
properties.put("mail.pop3.starttls.enable", "true");
Session emailSession = Session.getDefaultInstance(properties);
//create the POP3 store object and connect with the pop server
Store store = emailSession.getStore("pop3s");
store.connect(host, username, password);
//create the folder object and open it
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
// retrieve the messages from the folder in an array and print it
Message[] messages = emailFolder.getMessages();
System.out.println("messages.length---" + messages.length);
for (int i = 0, n = messages.length; i < n; i++) {
Message message = messages[i];
Object body = message.getContent();
System.out.println("---------------------------------");
System.out.println("Email Number " + (i + 1));
System.out.println("Subject: " + message.getSubject());
System.out.println("From: " + message.getFrom()[0]);
System.out.println("Text: " + body );
}
//close the store and folder objects
emailFolder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Does anyone know how can I get all?

Check your POP settings in Gmail or switch to IMAP.

I have just test it if you have no need to use pop you should try imap
your chech method will be like this below. Idid test it i can my mails without restriction. But also if you configure your gmail account for a specific number you will receive that number.
public static void check() {
String host = "imap.gmail.com";
String username = "user";
String password = "passwd";
try {
//create properties field
Properties properties = new Properties();
properties.setProperty("mail.imap.ssl.enable", "true");
Session emailSession = Session.getDefaultInstance(properties);
//create the POP3 store object and connect with the pop server
Store store = emailSession.getStore("imap");
store.connect(host, username, password);
//create the folder object and open it
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
// retrieve the messages from the folder in an array and print it
Message[] messages = emailFolder.getMessages();
System.out.println("messages.length---" + messages.length);
for (int i = 0, n = messages.length; i < n; i++) {
Message message = messages[i];
Object body = message.getContent();
System.out.println("---------------------------------");
System.out.println("Email Number " + (i + 1));
System.out.println("Subject: " + message.getSubject());
System.out.println("From: " + message.getFrom()[0]);
System.out.println("Text: " + body );
}
//close the store and folder objects
emailFolder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}

How to get Bounced mails in java

I am implementing a Bulk mail application, in this applica This link.
I am able to connect to the server and and send the emails to the destination addresses, but I want to identify the undelivered mails.
By using below program I am able to get the email subjects. But based on the subject it will be difficult to identify the exact undelivered mails.
public static void main(String[] args) {
Properties props = System.getProperties();
props.setProperty("mail.host", host);
props.setProperty("mail.user", user);
props.setProperty("mail.from", from);
//props.setProperty("mail.debug", "true");
//props.setProperty("mail.domain", domain);
try {
Session session = Session.getInstance(props, null);
Store store = session.getStore(protocol);
Session session1 = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);
}
});
System.out.println((store.isConnected())?"Already Connected":"Not Already Connected");
store.connect(host, port, user, password);
Folder inbox = store.getFolder("INBOX");
System.out.println("folder>>>" + inbox.getFullName() + "<<<");
System.out.println("folder URLName>>>" + inbox.getURLName() + "<<<");
System.out.println((inbox.exists()?"folder exists":"folder does not exist"));
int folderType = inbox.getType();
System.out.println("folder type>>>" + folderType + "<<<");
inbox.open(Folder.READ_WRITE);
System.out.println("Message Count:" + inbox.getMessageCount());
Message[] m = inbox.getMessages();
for (int x = 0; x < m.length; x++) {
System.out.println(m[x].getSubject());
}
inbox.close(false);
store.close();
}catch(Exception e) {
System.out.println(e.getLocalizedMessage());
}
}
How can I get the undelivered mails(Bounced).
I am using Hmailserver as my mail server.
You can use this below code
MimeMessage payload = (MimeMessage) message.getPayload();
Multipart mp = (Multipart) payload.getContent();
for (int i = 0; i < mp.getCount(); i++) {
BodyPart bodyPart = mp.getBodyPart(i);
StringWriter writer = new StringWriter();
IOUtils.copy(bodyPart.getInputStream(), writer);
System.out.println("Content inputstream: " + writer.toString());
}

}
}
But I am getting the following exceptions:

But i have recieved an email from gmail in my inbox which is saying that
"We recently blocked-in a sign in attempt to your Google Account".
How can i make the program to work properly?
Change Your emailSession variable with
Session emailSession = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
});
As said by Gmail
Some apps and devices use less secure sign-in technology, which makes
your account more vulnerable. You can turn off access for these apps,
which we recommend, or turn on access if you want to use them despite
the risks. Learn more
Just click below link and disable Gmail security settings.It will work.

How to delete messages from specific sender in gmail using java

i want to delete messages from speicifc sender in my INBOX folder using java.
Here i found this code to get all emails from gmail.
How can i get the specific sender (sender#gmail.com) and delete it or move it to trash folder.
Thank you
Code:
import com.sun.mail.imap.IMAPFolder;
import com.sun.mail.pop3.POP3Folder;
import java.util.Properties;

public class CheckingMails {
public static void check(String host, String storeType, String user,
String password)
{
try {
//create properties field
Properties properties = new Properties();
properties.put("mail.pop3.host", host);
properties.put("mail.pop3.port", "995");
properties.put("mail.pop3.starttls.enable", "true");
Session emailSession = Session.getDefaultInstance(properties);
//create the POP3 store object and connect with the pop server
Store store = emailSession.getStore("pop3s");
store.connect(host, user, password);
//create the folder object and open it
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
// retrieve the messages from the folder in an array and print it
Message[] messages = emailFolder.getMessages();
System.out.println("messages.length---" + messages.length);
for (int i = 0, n = messages.length; i < n; i++) {
Message message = messages[i];
System.out.println("---------------------------------");
System.out.println("Email Number " + (i + 1));
System.out.println("Subject: " + message.getSubject());
System.out.println("From: " + message.getFrom()[0]);
System.out.println("Text: " + message.getContent().toString());
}
//close the store and folder objects
emailFolder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
String host = "pop.gmail.com";// change accordingly
String mailStoreType = "pop3";
String username = "myemail#gmail.com";// change accordingly
String password = "password";// change accordingly
check(host, mailStoreType, username, password);
}
}
Using Gmail's RESTful API this is possible
Users.messages: list to get the messages
and
Users.messages: trash to send to trash

Exporting all emails from Gmail with Java Mail API

So i am trying to write a program that will grab all my emails from my email adress and save them to a text file, the problem i am having is grabbing more then 1 email with the Java Mail API.
This is what i use to get an email which works fine, but i want to get every email in my inbox:
public static void checkMail(String username, String password) {
Properties props = new Properties();
props.setProperty("mail.store.protocol", "imaps");
try {
Session session = Session.getInstance(props, null);
Store store = session.getStore();
store.connect("imap.gmail.com", username, password);
Folder inbox = store.getFolder("INBOX");
inbox.open(Folder.READ_ONLY);
Message msg = inbox.getMessage(inbox.getMessageCount());
Address[] in = msg.getFrom();
for (Address address : in) {
System.out.println("FROM:" + address.toString());
}
Multipart mp = (Multipart) msg.getContent();
BodyPart bp = mp.getBodyPart(0);
System.out.println("SENT DATE:" + msg.getSentDate());
System.out.println("SUBJECT:" + msg.getSubject());
System.out.println("CONTENT:" + bp.getContent());
} catch (Exception mex) {
mex.printStackTrace();
}
}
If someone could possibly show me how to do this or explain it then that would be greatly appreciated.
If you want all mails in folder inbox do this:
public static void checkMail(String username, String password) {
Properties props = new Properties();
props.setProperty("mail.store.protocol", "imaps");
try {
Session session = Session.getInstance(props, null);
Store store = session.getStore();
store.connect("imap.gmail.com", username, password);
Folder inbox = store.getFolder("INBOX");
inbox.open(Folder.READ_ONLY);
Message[] msgs = inbox.getMessages();
for (Message msg : msgs) {
try {
Address[] in = msg.getFrom();
for (Address address : in) {
System.out.println("FROM:" + address.toString());
}
Multipart mp = (Multipart) msg.getContent();
BodyPart bp = mp.getBodyPart(0);
System.out.println("SENT DATE:" + msg.getSentDate());
System.out.println("SUBJECT:" + msg.getSubject());
System.out.println("CONTENT:" + bp.getContent());
} catch (Exception e) {
e.printStackTrace();
}
}
// close folder and store (normally in a finally block)
inbox.close(false);
store.close();
} catch (Exception mex) {
mex.printStackTrace();
}
}
If you want mails from other folders to you have to do the same for all folders.
You get them with store.getDefaultFolder().list() (do this recursive for all folders because folders can have subfolders)
protected void recurseFolders(final Folder folder) {
// folder can hold messages
if ((folder.getType() & Folder.HOLDS_MESSAGES) != 0) {
// process them
}
// folder can hold other folders
if ((folder.getType() & Folder.HOLDS_FOLDERS) != 0) {
for (final Folder subfolder : folder.list()) {
// process them recursive
recurseFolders(subfolder);
}
}
}
