web.config email settings. Not receiving email from contact form,

Trying to make my first contact email form.  I am using the following web.config mailsettings but am not receiving the emails.  The test/book site is live if that makes a difference. aex1.com     I used code from wrox book with a contact form and submit button. Should I be using "postmaster@discountasp.net" or my email "johndoe@aex1.com  ?  In outlook I am using smtp port 587 if that makes a difference.  Should the username and password be blank or filled in? When trying at an earlier date I did receive some delivery failure emails that said "could not deliver to johndoe@aex1.com.com  (2 .com's in email?)  Thanks

network host="localhost" port="25
is your email server on the same server where you have the site? because he is trying to authenticate on locahost to send mail.. he should be trying to authenticate on your email server,

I tried all the variations of setting up the web.config as suggested in the links above. No luck. I am not testing locally, the site is live at aex1.com, under the about tab there is a contact form.
Here is the code from the contact form,

Imports System.Net.Mail

Partial Class Controls_ContactForm
  Inherits System.Web.UI.UserControl

  Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
    If txtPhoneHome.Text IsNot String.Empty Or txtPhoneBusiness.Text IsNot String.Empty Then
      args.IsValid = True
    Else
      args.IsValid = False
    End If
  End Sub

  Protected Sub btnSend_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSend.Click
    If Page.IsValid Then
      Dim fileName As String = Server.MapPath("~/App_Data/ContactForm.txt")
      Dim mailBody As String = System.IO.File.ReadAllText(fileName)

      mailBody = mailBody.Replace("##Name##", txtName.Text)
      mailBody = mailBody.Replace("##Email##", txtEmailAddress.Text)
      mailBody = mailBody.Replace("##HomePhone##", txtPhoneHome.Text)
      mailBody = mailBody.Replace("##BusinessPhone##", txtPhoneBusiness.Text)
      mailBody = mailBody.Replace("##Comments##", txtComments.Text)

      Dim myMessage As MailMessage = New MailMessage()
      myMessage.Subject = "Response from web site"
      myMessage.Body = mailBody

      myMessage.From = New MailAddress("you@yourprovider.com", "Sender Name Here")
      myMessage.To.Add(New MailAddress("you@yourprovider.com", "Receiver Name Here"))

      Dim mySmtpClient As SmtpClient = New SmtpClient()
      mySmtpClient.Send(myMessage)

      lblMessage.Visible = True
      FormTable.Visible = False
      System.Threading.Thread.Sleep(5000)
    End If
  End Sub
End Class
