I am creating a webform to send an email message using the System.Web.Mail Namespace. When the user clicks the submit button and the message is actually sent I want to redirect them to a confirmation page letting them know the message was sent succesfly.

How can I determine if the message was sent succesfly.

Here is the code I have so far

Code:
    Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click


        If (Page.IsValid) Then

            Dim newMail As New MailMessage

            Try

                newMail.From = txtSendersEmailAddress.Text
                newMail.From = txtSenderName.Text
                newMail.Subject = ddlQueryType.SelectedValue + " " + txtSubject.Text
                newMail.To = "[email protected]"
                newMail.BodyFormat = MailFormat.Text
                newMail.Body = newMail.From + newMail.Subject + txtMessage.Text
                SmtpMail.SmtpServer = "your.smtpserver.net.net"
                SmtpMail.Send(newMail)

          Catch ex As Exception

            Finally

                newMail = Nothing

            End Try

        End If
