[exim] Couldn't chown message log

Hello,

I've installed the last version of Exim on a FC 8, I configure Exim with
the exim.conf file.
But when I try to do :

/[admin@test-exim ~]$ exim -v -odf alice
Loading lookup modules from /usr/lib/exim/4.69-7.fc10/lookups
Loaded "mysql.so" (1 lookup types)
Loaded "pgsql.so" (1 lookup types)
Loaded 2 lookup modules

.

I've have a very simple conf file based on the Configuration C1 by Jason
Meers.

Thanks.


PS: I'm french so sorry for my english.
