You sent a message as root. Exim is therefore privileged, whatever its
permissions and ownership.

The transport is running as uid=1001. It calls Exim in order to create a
new message.

There is the problem. Why has Exim done that, I wonder? What do you have
in the rest of your Exim configuration? In particular, what have you set
in the "security" option?
