Ho! Ho! Excuse my laughing, but I had to go to some trouble to
*preserve* the case for transmission, because when early versions of
Exim did not preserve it, people complained!
What you should do is use a redirection to force the case.

Why not just force lower case directly?

Isn't that exactly the same as
data = ${lc:$local_part}
? Actually no, it isn't, because it never fails. The MySQL lookup will
fail for non-existent users. But since you do the lookup again in the
next router, you don't really need to do it twice.
