[Exim] rewrite rule and mysql

Hi all,

I'm trying to use mysql on rewrite rules like this:

*@domain.com    ${lookup mysql{select alias from exim where
user='$1'}{$value}fail}        tT

exim is complaining with this error:

"unknown rewrite flag character 'm' (could be missing quotes round
replacement item)"

I really don't find which quotes is missing.

What am I missing?

Thanks for your help.

Laurent.
