SMTPSendFailedException Occurs

[Balachandar Nayak]

Hi,

I have a problem while executing this program.

import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
class SimpleMail {
 public static void main(String[] args) throws Exception{
 
        Properties props = new Properties();
        props.setProperty("mail.transport.protocol", "smtp");
        props.setProperty("mail.host", "mail.stras.com");
        props.setProperty("mail.user", "[e-mail]");
        props.setProperty("mail.password", "12121");
        props.setProperty("mail.smtp.port","25");
        props.setProperty("mail.smtp.auth", "true");
        Session mailSession = Session.getDefaultInstance(props, null);
        Transport transport = mailSession.getTransport();
        MimeMessage message = new MimeMessage(mailSession);
        message.setContent("This is a test", "text/plain");
        message.addRecipient(Message.RecipientType.TO,
             new InternetAddress("[e-mail]"));
        transport.connect();
        transport.sendMessage(message,
        message.getRecipients(Message.RecipientType.TO));
        transport.close();
        }
   }

This program compiles fine (no error) but while execution of this prg throws an error
com.sun.mail.smtp.SMTPSendFailedException: 530 Authentication required

try

props.setProperty("mail.user", "jim");

instead of

props.setProperty("mail.user", "[e-mail]");

Ensure that port 25 is not blocked.
