Hi yzme,

The question is why no exception is thrown if you send an email to xcxzczczcxz@yahoo.com? An AddressException is only thrown when the syntax of the email address doesn't comply with RFC822.

The point is there's nothing wrong with this email address. Your SMTP server will just send your email to the yahoo mail servers. The yahoo server will find out it can't deliver the email. Then the yahoo server has two options: bounce the message or ignore it. If it bounces the message, it appears in the email folder of the sender of the email message. For security reasons it's often better to just ignore it.

Also, there's no reliable way to find out if an email address exists.

Kind regards,

Sigiswald

if anybody have done the javamail dsn delivery status checking before...

Yzme,

Check the following link for reference

also check the following code

package com.msit.webad.mail;

import java.util.*;

import javax.mail.*;

import javax.mail.internet.*;

import java.text.DateFormat;

import java.text.SimpleDateFormat;

class AutoMail extends TimerTask {

public void run() {

java.util.Date dt = new Date();

java.util.Calendar c = java.util.Calendar.getInstance();

c.setTime(dt);

c.add(Calendar.DATE,-7);

DateFormat df = DateFormat.getDateInstance(DateFormat.MEDIUM);

String s = DateFormat.getDateInstance(DateFormat.MEDIUM).format(dt);

dt.before(dt);

String body = "This is an Autogenerated Mail."+

"some message"+

"for the period from "df.format(c.getTime())"to" +s;

ResourceBundle web = ResourceBundle.getBundle("webads");

String to = web.getString("yzme@mail.com");

sendMail("anil@mail.com", to, "message", body);

}// end of run...

public boolean sendMail(String fromID, String toID, String mailSubject,

String mailBody) {

// Write mail sending logic here

String from = fromID;

String to = toID;

String subject = mailSubject;

String body = mailBody;

String host = "host name";

// create some properties and get the default Session

try {

Properties props = new Properties();

props.put("mail.smtp.host", host);

Session session = Session.getDefaultInstance(props, null);

// create a message

Message msg = new MimeMessage(session);

msg.setFrom(new InternetAddress(from));

InternetAddress[] address = { new InternetAddress(to) };

msg.setRecipients(Message.RecipientType.TO, address);

msg.setSubject(subject);

msg.setSentDate(new Date());

msg.setText(body);

Transport.send(msg);

// System.out.println("Mail has been sent");

// if mail sent , return true, else return false

return true;

} catch (Exception mex) {

System.out.println("Error " + mex);

return false;

}

}// end of sendMail...

}

ps:change the code according to the requirement and then try it.

Hi yzme,

excuse me for delayed reply.

Have you included the required jar files. i.e.mail.jar and activation.jar files.

if not please include them and let me know the status.
