[issue11281] smtplib: add ability to bind to specific source IP address/port

[Paulo Scardine]

New submission from Paulo Scardine <paulo at scardine.com.br>:

In smtplib there is now way to bind to an specific source address on a machine with multiple interfaces; also, there no way to control the source port for the connection.

Since 2.7, socket.create_connection accepts a source_address parameter, a (host, port) tuple for the socket to bind to as its source address before connecting. If host or port are '' or 0 respectively the OS default behavior will be used.

I would like to add source_ip and source_port parameters to smtplib.SMTP, default to '' and 0 respectively.

It is a small change with no impact over existing code. Should I submit a patch?
