title: Display SMTP message to user prior to sending in .Net
body: <p>When using MAPI the send command has parameters to display a login and the mail dialog prior to sending. For instance: mapiMessage.Send(MapiSendMailFlags.LogonUI | MapiSendMailFlags.Dialog);</p>
  
  <p>Does anyone know of a way to do this for the SMTP Send command in .Net 4.0?</p>
