Javamail Auto-reply for my domain - jakarta-mail

Question

Javamail Auto-reply
I would truly like to auto-reply to an email using Javamail.
I already use my domain email to send a confirmation code during registration.
What I need now is when an email is sent to choices#mydomain.com I can auto-reply with a canned email based on parsing out and reading the received email. It would be nice to include the username in the reply.
Thank you for your help!

Answer 1

This simplest approach is to write a program that monitors your mailbox and creates and sends a reply based on every message it sees. The JavaMail download bundle includes a sample program monitor.java that will get you started. The MimeMessage.reply method will be helpful. You'll have to fill in the content of the reply message yourself. Various other JavaMail sample programs will show you how to send a message once you've created it.
And don't forget to read the JavaMail FAQ.

Nice thinking John,I had the same problem in my project, in JSP and I solved it as shown below with java class as ReadingMail
package com;import java.io.*;import java.util.*;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
public class ReadingMail {
public static void main(String args[]) throws Exception {
try{
String host = "pop.gmail.com";
String user="username";
String password="password";
// Get system properties
Properties properties = System.getProperties();
// Get the default Session object.
Session session = Session.getDefaultInstance(properties, null);
// Get a Store object that implements the specified protocol.
Store store = session.getStore("pop3s");
//Connect to the current host using the specified username and password.
store.connect(host, user, password);
//Create a Folder object corresponding to the given name.
Folder folder = store.getFolder("inbox");
// Open the Folder.
folder.open(Folder.READ_ONLY);
Message[] message = folder.getMessages();
// Display message.
for (int i = 0; i < message.length; i++) {
System.out.println("------------ Message " + (i + 1) + " ------------");
System.out.println("SentDate : " + message[i].getSentDate());
System.out.println("From : " + message[i].getFrom()[0]);
System.out.println("Subject : " + message[i].getSubject());
System.out.print("Message : ");
InputStream stream = message[i].getInputStream();
while (stream.available() != 0) {
System.out.print((char) stream.read());
}
System.out.println();
}
folder.close(true);
store.close();
}
catch(Exception e)
{
System.out.println(e);
}
}
public String Manu()
{
String email=null;
try{
String host = "pop.gmail.com";
// String user = "xyz";
// String password = "12345";
String user="username#gmail.com";
String password="password";
// Get system properties
Properties properties = System.getProperties();
// Get the default Session object.
Session session = Session.getDefaultInstance(properties, null);
// Get a Store object that implements the specified protocol.
Store store = session.getStore("pop3s");
//Connect to the current host using the specified username and password.
store.connect(host, user, password);
//Create a Folder object corresponding to the given name.
Folder folder = store.getFolder("inbox");
// Open the Folder.
folder.open(Folder.READ_ONLY);
Message[] message = folder.getMessages();
// Display message.
for (int i = 0; i < message.length; i++) {
System.out.println("------------ Message " + (i + 1) + " ------------");
// System.out.println("SentDate : " + message[i].getSentDate());
//System.out.println("From : " + message[i].getFrom()[0]);
email=message[i].getFrom()[0]==null?null:((InternetAddress) message[i].getFrom()[0]).getAddress();
System.out.println("From addrss is..........................."+email);
// System.out.println("Subject : " + message[i].getSubject());
System.out.print("Message : ");
InputStream stream = message[i].getInputStream();
while (stream.available() != 0) {
System.out.print((char) stream.read());
}
System.out.println();
}
folder.close(true);
store.close();
}
catch(Exception e)
{
System.out.println(e);
}
return email;
}
You can fetch the username from the database and provide it as message in this program.
