//  ------------------------------------------------------------------------
//  The FetchHeaders method is deprecated:

bundleObj := imap.FetchHeaders(mset.ControlInterface);
if (imap.LastMethodSuccess = 0) then
  begin
    Memo1.Lines.Add(imap.LastErrorText);

//  Your application creates a new, empty EmailBundle object which is passed 
//  in the last argument and filled upon success.
