I've not worked with smtplib, but the error (550, 'authentication required'), suggests
to me, that you have to login into the mail-Server, otherwise the server would not
accept emails.
Looking into the doc for smtplib, the Class SMTP has method for that:

login(self, user, password)
    Log in on an SMTP server that requires authentication.

    The arguments are:
        - user:     The user name to authenticate with.
        - password: The password for the authentication.

    If there has been no previous EHLO or HELO command this session, this
    method tries ESMTP EHLO first.

    This method will return normally if the authentication was successful.

    This method may raise the following exceptions:

     SMTPHeloError            The server didn't reply properly to
                              the helo greeting.
     SMTPAuthenticationError  The server didn't accept the username/
                              password combination.
     SMTPException            No suitable authentication method was
                              found.
