    A :class:`SMTP` instance encapsulates an SMTP connection.  It has methods
    that support a full repertoire of SMTP and ESMTP operations. If the optional

-   with those parameters during initialization.  If specified, *local_hostname* is
-   used as the FQDN of the local host in the HELO/EHLO command.  Otherwise, the
-   local hostname is found using :func:`socket.getfqdn`.  If the
-   :meth:`connect` call
-   returns anything other than a success code, an :exc:`SMTPConnectError` is
-   raised. The optional *timeout* parameter specifies a timeout in seconds for
-   blocking operations like the connection attempt (if not specified, the
-   global default timeout setting will be used). The optional source_address
-   parameter allows to bind to some specific source address in a machine with
-   multiple network interfaces, and/or to some specific source TCP port. It
-   takes a 2-tuple (host, port), for the socket to bind to as its source
-   address before connecting. If omitted (or if host or port are ``''`` and/or
