Urgent, please respond with haste

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.

responding for duty!

Seriously though, leave URGENT, deadline, etc out of post titles.

Maybe you should ask your email host (MSN) for the server, or an even better idea would be to ask an email server question, on an email forum.

[Bagzli]

my appology for double post.

[Bagzli]

ok

and

its called java mail so hey I figured, why not ask on java forums? And there is really no need to get angry over such a small thing, If i have it in wrong section just tell me and I'll repost in the proper one.

[sunde887]

I hope no anger was meant. It's perfectly acceptable to post it here if it is indeed java mail. If, however; it's very email server related you may want to ask it somewhere more specific. That being said, I'm sure one of the people here can help you out (unfortunately I am not one of them in this matter).

[Bagzli]

it was meant for the other guy and thanks for the header tips.

[sunde887]

it was meant for the other guy and thanks for the header tips.

Hehe, I was actually aiming the 'I hope no anger was meant' at him.

[jammas615]

Sorry, i had no intention of coming across as angry.
