Javax.mail.SendFailedException: 553 sorry, that domain isn't in my list of

Question

i have put all the lines in the code required to set the server name and the username and the password but it still gives me the error. i have the following code to send the mail.
package com.wesra.mail;
import java.io.PrintStream;
import java.util.Hashtable;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class SendEmail extends Authenticator
InternetAddress from = null;
InternetAddress to = null;
InternetAddress cc = null;
InternetAddress bcc = null;
String subject = null;
Object body = null;
Message msg = null;
static Session session = null;
String msgText = null;
Properties prop = null;
MimeMultipart mimemultipart = null;
public SendEmail()
from = null;
to = null;
cc = null;
bcc = null;
subject = null;
body = null;
msg = null;
msgText = null;
prop = null;
mimemultipart = null;
msgText = new String("");
prop = System.getProperties();
mimemultipart = new MimeMultipart();
public void setDetails(String s, String s1, String s2, String s3, String s4, String s5)
throws Exception
from = new InternetAddress(s1);
to = new InternetAddress(s);
cc = new InternetAddress(s2);
bcc = new InternetAddress(s3);
subject = new String(s4);
body = new MimeBodyPart();
prop.put("mail.smtp.host", s5);
public boolean sendEmail(String s, int i)
throws Exception
session = Session.getDefaultInstance(prop, null);
MimeMessage mimemessage = new MimeMessage(session);
MimeMultipart mimemultipart1 = new MimeMultipart();
if(i > 1)
mimemessage.setRecipient(javax.mail.Message.RecipientType.CC, cc);
if(i > 2)
mimemessage.setRecipient(javax.mail.Message.RecipientType.BCC, bcc);
mimemessage.setRecipient(javax.mail.Message.RecipientType.TO, to);
mimemessage.setSubject(subject);
msgText = s;
MimeBodyPart mimebodypart = new MimeBodyPart();
mimebodypart.setContent(msgText, "text/html");
mimemultipart1.addBodyPart(mimebodypart);
mimemessage.setContent(mimemultipart1);
mimemessage.setFrom(from);
System.out.println("Message is being sent...");
Transport.send(mimemessage);
System.out.println("Message Sent Successfully");
return true;
i write the following lines to call the code.
se1.setDetails(to,from,to1,to2,subject,server);// this is called with the appropriate parameters with the server being either wesra.com,wesra.in or nmims.edu but none of that works.please check it and let me know what is wrong.
boolean sentstatus=se1.sendEmail(msgText1,number);

Answer 1

It sounds like a configuration problem with your SMTP server. Perhaps the machine from which you're connecting to the mail server isn't allowed to send mail to other domains. That'll be something you need to fix on the mail server.
Anyway, I'd suggest plugging that error message into Google... you'll get hundreds of matches.
