[RESOLVED] [2005] E-Mailing?

[Mindstorms]

I'm trying to make an e-mailprogram and got this code:

'create the mail message
        Dim mail As New System.Net.Mail.MailMessage()
 
        'set the addresses
        mail.From = New System.Net.Mail.MailAddress("[email protected]")
        mail.To.Add("[email protected]")
 
        'set the content
        mail.Subject = "This is an email"
        mail.Body = "this is the body content of the email."
 
        'send the message
        Dim smtp As New System.Net.Mail.SmtpClient("127.0.0.1")
        smtp.Send(mail)

But can he e-mail from 127.0.0.1 (wich is my computer -> localhost) and what is the strange error he gives for

smtp.Send(mail)

"SmtpException was unhandled" What does that mean?

Cheers,
Thomas
