  Dim oPop3 As ANPOPLib.POPMAIN
  Dim oMsg As ANPOPLib.POPMSG
  Dim nRet, nTotalSize As Integer
  Dim err As String
  
  Set oPop3 = new ANPOPLib.POPMAIN 'Create object instance
  Set oMsg  = new ANPOPLib.POPMSG
   
  'For IMAP4 server, please add the following code
  'oPop3.IMAP4Connection = 1
  'oPop3.ServerPort = 143
    
  err = ""
  nRet = oPop3.Connect( pop3Server, pop3User, pop3Password ) 'Connect pop3 server
  If nRet <> 0 Then
