//import javax.pop3.*;
public class ReceiveMail{
public static void main(String[] args) {
// SUBSTITUTE YOUR ISP's POP3 SERVER HERE!!!
String host = "www.modomail.com";
// SUBSTITUTE YOUR USERNAME AND PASSWORD TO ACCESS E-MAIL HERE!!!
String user = "pranavakumar";
String password = "karuppiah";
// 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(),null);
try {
// Get a Store object
Store store = session.getStore("pop3");
store.connect(host, user, password);
// Get "INBOX"
Folder fldr = store.getFolder("INBOX");
fldr.open(Folder.READ_WRITE);
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

System.out.write(c);
// Uncomment to set "delete" flag on the message
//m.setFlag(Flags.Flag.DELETED,true);
} //End of for
// "true" actually deletes flagged messages from folder
fldr.close(true);
store.close();
catch (MessagingException mex) {
// Prints all nested (chained) exceptions as well
mex.printStackTrace();
catch (IOException ioex) {
ioex.printStackTrace();
} //End of class

NORoute to host Exception : Operation timed out no Further InformationThis means that there is no path in the network between your computer and the one you want to connect to. Sometimes this is because you misspelled the name of the server. Sometimes it is because there is no such server. Sometimes it is because there is a firewall or a proxy server blocking the path. It is never a programming problem.
// SUBSTITUTE YOUR ISP's POP3 SERVER HERE!!!
String host = "www.modomail.com";That is a very unlikely name for a POP3 server. First step is to confirm it is actually the name of the server you want to connect to. (Ask the administrator of the server.) If it is, next step is to fix your network configuration problem. (Ask the network administrator.)
