[issue6328] login() function failed in smtplib with message "argument 1 must be bytes or buffer, not str"

Hi folks,

I encountered the following error with this Python code snippet. (I ran
it with Python 3.0.1). Judging from the error as shown in IDLE debugger,
the error was buried inside python. 

  try:
    server = smtplib.SMTP(EmailConfig.smtpServerName)
    server.set_debuglevel(3)
    print(server)
    server.login(bytes(EmailConfig.mailUser, encoding='ascii'),
bytes(EmailConfig.mailPass, encoding='ascii'))
    print('Login is successful.')
    failed = server.sendmail(from_addr, to_addr, text_msg)
  except Exception as ex:
    print('Error in communicating with SMTP server', ex)
  else:
    if failed : print('Failed in sending email with following
reason:\n', failed)


***********************************************
The output from terminal is:
