[Exim] Mysql Rewrites

Again on the subject of MySQL I am attempting to get header rewriting
working with the database.

The following statement is used:

MYSQL_REWRITE = select rewrite from rewrites where address =
'${quote_mysql:$domain}' or address = '${quote_mysql:$local_part}'

and rewrite line:

*@*     {lookup_mysql{MYSQL_REWRITE}{$value}fail}       T

This is the line it keeps complaining about.

Any pointers would be appreciated.
