A :class:`SMTP` instance encapsulates an SMTP connection. It has methods
that support a full repertoire of SMTP and ESMTP operations. If the optional
host and port parameters are given, the SMTP :meth:`connect` method is called
with those parameters during initialization. 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
0 respectively) the OS default behavior will be used.

A :class:`SMTP_SSL` instance behaves exactly the same as instances of

required from the beginning of the connection and using :meth:`starttls` is
not appropriate. If *host* is not specified, the local host is used. If

mileage might vary.
