You try to connect to your localhost on Port 25 for sending email. Because of
the Windows-Error 10054 'Connection reset by peer', I think you do not have an
email server running on your server.
Perhaps you can supply your email server in smtplib.SMTP().
Here is the pydoc of the init-Method:

__init__(self, host='', port=0, local_hostname=None)
    Initialize a new instance.

    If specified, `host' is the name of the remote host to which to
    connect.  If specified, `port' specifies the port to which to connect.
    By default, smtplib.SMTP_PORT is used.  An SMTPConnectError is raised
    if the specified `host' doesn't respond correctly.  If specified,
    `local_hostname` is used as the FQDN of the local host.  By default,
    the local hostname is found using socket.getfqdn().
