I have been wrong. The message does not originate from your
mail server.

"smtplib" is part of the Python runtime library.

Looking at the "smtplib" source and your traceback reveals:

  "smtplib.SMTP.__init__" is trying to determine the
  local hostname. The code looks like this:

        if local_hostname is not None:
            self.local_hostname = local_hostname
        else:
            # RFC 2821 says we should use the fqdn in the EHLO/HELO verb, and
            # if that can't be calculated, that we should use a domain literal
            # instead (essentially an encoded IP address like [A.B.C.D]).
            fqdn = socket.getfqdn()
            if '.' in fqdn:
                self.local_hostname = fqdn
            else:
                # We can't find an fqdn hostname, so use a domain literal
                addr = socket.gethostbyname(socket.gethostname())
# your exception is raised in the line above
                self.local_hostname = '[%s]' % addr
  

This means that you local system is in a strange state.
Probably, it is unable to determine its hostname.

Try (in an interactive Python interpreter):

    import socket
    socket.gethostname()
    socket.gethostbyname(socket.gethostname())
