title: Extra Header info from Indy message
body: <p>I'm reading email headers from an IMAP account using Indy in Delphi 2007.</p>
  
  <p>The Msg (TidMessage) Date property gives the date and time the email was sent (from the client), I'm trying to get the date and time the email was received by the server by inspecting the ExtraHeaders property, can this be done?</p>
  
  <p>So far I've tried Msg.ExtraHeaders.Values['Received'] and Msg.ExtraHeaders.Text, both of which returned an empty string.</p>
  
  <p>Am I going about this the right way?</p>
