send email smtp setup

Hi, I'm having problem send email using System.Web.Mail, the messages just sit in mailroot/queue folder and is not sent out

I already set up smtp server with relay 127.0.0.1 or localhost
and Im using this code

Code:

---

Dim mymessage As New MailMessage
mymessage.To = "[email protected]"
mymessage.From = "[email protected]"
mymessage.Subject = "Password Request"
mymessage.Body = "hello"
mymessage.BodyFormat = MailFormat.Text
SmtpMail.SmtpServer = "127.0.0.1"
SmtpMail.Send(mymessage)

---

Is there anything else that I need to setup?

Im using xp with IIS 5.1

Thanks,
Jewel
