This bit of the error message is generated by a call to mysql_error(),
so it is MySQL that is generating this text. All Exim has done is to
call mysql_real_connect() and print the error when it failed.

Exim passes the server name to MySQL. It appears to be doing that
correctly. You'll have to dig in MySQL to see what that error message
actually means.
