That bit there is the important info. Unfortunately, they didn't say
what IP they tried to connect from, and unless you can infer anything
else about them (such as IPs used by previous messages from them that
you did accept), you need it to search for in your logs. You might
have to contact the operator of tha system and ask.

Then: search your Exim mainlog for connections from that IP. If there
is one that matches the expected date/time, what was logged about it?

If none such: do you run a firewall? What about its logs?
