Two problems: The SMTPRecipientsRefused class should not inherit
SMTPResponseException, since it doesn't provide the smtp_code and
smtp_error attributes.  My patch for not adding an extra CRLF was
apparently forgotten.  The enclosed patch fixes these two problems.

  a callable object that takes two arguments, a module name and an
  object name, and returns an object.  If the attribute is unset, then
  the default mechanism is used.

  This feature provides an additional mechanism for controlling which
  classes can be used for unpickling.
