Imports System.Net.Mail


Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim Mail As New MailMessage
        Mail.Subject = "Test"
        Mail.To.Add("username@yahoo.co.uk")
        Mail.From = New MailAddress("username@yahoo.co.uk")
        Mail.Body = "Test Body"

        Dim SMTP As New SmtpClient("smtp.mail.yahoo.co.uk")

        SMTP.EnableSsl = True
        SMTP.Credentials = New System.Net.NetworkCredential("username", "password")
        SMTP.Port = "110"
        SMTP.Send(Mail)



    End Sub

Can anyone see where I am going wrong ? It just comes up with an error, fail to send.

~Thanks~
