[sireesha Makkapati]

Hi all,
I wanted to send a javaMail,i am geting the following error,

javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25
at javax.mail.Transport.send0(Transport.java:219)
at javax.mail.Transport.send(Transport.java:81)
at mailsample.sendEmail(mailsample.java:114)
at mailsample.main(mailsample.java:24)

My standard alone java code asd follows:

import java.util.Date;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class mailsample {

public static void main(String[] args) {
mailsample demo = new mailsample();
demo.sendEmail();
}
public void sendEmail() {
String from = "[e-mail]";
String to = "[e-mail]";
String subject = "Important Message";
String bodyText = "This is a important message with attachment";
String filename = "c:\\message.txt";
Properties properties = new Properties();
properties.put("mail.smtp.host", "localhost");
properties.put("mail.smtp.port", "25");
Session session = Session.getDefaultInstance(properties, null);
try {
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject(subject);
message.setSentDate(new Date());
MimeBodyPart messagePart = new MimeBodyPart();
messagePart.setText(bodyText);
// Set the email attachment file
MimeBodyPart attachmentPart = new MimeBodyPart();
FileDataSource fileDataSource = new FileDataSource(filename) {

@Override
public String getContentType() {
return "application/octet-stream"; }

}; attachmentPart.setDataHandler(new DataHandler(fileDataSource));
attachmentPart.setFileName(filename);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messagePart);
multipart.addBodyPart(attachmentPart);
message.setContent(multipart);
Transport.send(message);
} catch (MessagingException e) {
e.printStackTrace();
}
}
}

found some information like
i can disable McAfee Enterprise
Go to Viras scan console >> Access Protection >> Port Blocking tabe >> Rule >> check out check box for port 25 can solve this issue.

but i don't have this software,i have symantic end point protection software,there i don't have option like Viras scan console >> Access Protection

I am using virtual mechine, in Firewall.cpl in advance tab i tried by ticking the checkbox like INTERNET MAIL Server(SMTP) ,
still i am getting this error.

Please give me the solution.

Thanks in advance.

Do you have a mail server running on your machine ("localhost")?

The line " properties.put("mail.smtp.host", "localhost") " tells JavaMail that you want to use a mail server on your local machine, so you need one.

Could you please help me how to run local mail server ?

One of the easiest ways might be to run Apache James, an open source mail server written in Java.

Just specify a working outgoing SMTP server. Its a lot easier then running your own. If you use thunderbird, eudora, outlook, etc. there is an account setup page. In it, you specify the incoming and outgoing hosts for mail.

Just put that instead of "localhost" in your properties.

Getting a mail server properly and securely setup is a non-trivial effort.

I haven't used Notes this century, but I remember it as being very different from the usual. There is usually a "Internet Mail to Notes gateway" for your Notes installation. I suggest you buy a beer or other drink for your local Lotus Notes admin.
