The above error message comes in my application server. I have used java mail api in this program. This is the source code i have used.

package sendmail;

import javax.mail.*;
import javax.mail.internet.*;





public class SendMail extends Thread{

String userid;
String password;

String tomailid;

String frommailid="jobcentreuk.com";

String mailsubject="JOB CENTRE Registration ....";
String content;


public SendMail(String userid,String password,String tomailid){

this.userid=userid.replace(' ','%');
this.password=password;
this.tomailid=tomailid;


content="Welcome to jobcentreuk.com

";
content=content+" Your Login Name : "+userid+"
";
content=content+" Your Password : "+password+ "
";

content=content+"Thankyou for signing up at www.jobcentreuk.com";

start();

}


public void run(){

try{

java.util.Properties properties=System.getProperties();
Session sess=Session.getInstance(properties,null);
MimeMessage message =new MimeMessage(sess);

Address fromaddress=new InternetAddress(frommailid);
message.setFrom(fromaddress);

Address[] toaddresses =InternetAddress.parse(tomailid);
message.setRecipients(Message.RecipientType.TO,toaddresses);

message.setText(content);
message.setSubject("jobcentre Registration Confirmation");

Transport transport = sess.getTransport("smtp");

// get smtp name here
//transport.connect("md3.vsnl.net.in"," ", " ");
transport.connect("imi.demon.co.uk"," ", " ");


transport.sendMessage(message,message.getAllRecipients());
transport.close();


}catch(Exception e){
System.out.println("Error in Sending Mail "+e);
}
}

}




I think the problem is the smtp service name. This is dedicated server provider smtp address.

Is there any free smtp server available.

my dedicated server provider smtp address is

POST.demon.co.uk

my office smtp address is

imi.demon.co.uk

Kindily give the solution please.

with thanks,
