This method can be overwritten by backend implementations to open a network connection. It's up to the backend implementation to track the status of a network connection if it's needed by the backend. This method can be called by applications to force a single network connection to be used when sending mails. See the send_messages() method of the SMTP backend for a reference implementation. The default implementation does nothing.
