Need help with sending a text

[Bagzli]

Hi, i'm on a deadline here so i was wondering if somebody can point me in right direction.

Here is my code:

Properties props = new Properties();
                props.put("mail.smtp.host", "my-mail-server");
                props.put("mail.from", "me@example.com");
                Session session = Session.getInstance(props, null);

                try {
                    MimeMessage msg = new MimeMessage(session);
                    msg.setFrom();
                    msg.setRecipients(Message.RecipientType.TO,
                                      "example@msn.com");
                    msg.setSubject("JavaMail hello world example");
                    msg.setSentDate(new Date());
                    msg.setText("Hello, world!\n");
                    Transport.send(msg);
                } catch (MessagingException mex) {
                    out.println("send failed, exception: " + mex);
                }

directly taken from: JavaMail API documentation

Now here is the error I get when I run it.

send failed, exception: javax.mail.MessagingException: Unknown SMTP host: my-mail-server; nested exception is: java.net.UnknownHostException: my-mail-server

how do i find out the SMTP Host and my-mail-server? I want to use example@msn.com but if MSN is not compatible i'm willing to get a new email address with a compatible host.

Hi Bagzli

what is my-mail-server?
you can try

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


you can also study following code for it

Properties props = new Properties();
		props.put("mail.smtp.host", "smtp.gmail.com");
		props.put("mail.smtp.socketFactory.port", "465");
		props.put("mail.smtp.socketFactory.class",
				"javax.net.ssl.SSLSocketFactory");
		props.put("mail.smtp.auth", "true");
		props.put("mail.smtp.port", "465");
 
		Session session = Session.getDefaultInstance(props,
			new javax.mail.Authenticator() {
				protected PasswordAuthentication getPasswordAuthentication() {
					return new PasswordAuthentication("username","password");
				}
			});
 
		try {
 
			Message message = new MimeMessage(session);
			message.setFrom(new InternetAddress("from@no-spam.com"));
			message.setRecipients(Message.RecipientType.TO,
					InternetAddress.parse("to@no-spam.com"));
			message.setSubject("Testing Subject");
			message.setText("Dear Mail Crawler," +
					"\n\n No spam to my email, please!");
 
			Transport.send(message);
 
			System.out.println("Done");
 
		} catch (MessagingException e) {
			throw new RuntimeException(e);
		}
