If that really was "XXXX", the client is sending a junk SMTP command.

Exim logs the incident, and sends back an error response, as you might
expect.

The client then sends a HELO command.

The client is behaving weirdly.
(1) It shouldn't be sending XXXX. It should be sending EHLO (probably).
(2) It shouldn't be sending 10.0.1.2 as an IP address, because that is
not a public IP address.
Unless the client belongs to you, I would just ignore this mess.
