What do you call the configdirectory for cyrus ? I have different places 
with cyrus (I'm using the standard package provided with SuSE Linux / 
SLES 10) :

1. I have a "cyrus" user with all binaries inside "bin" in the homedir
2. In "/var/spool/imap/user/" there are all user accounts with the mails...

But I think I understand, I have to create the "log" directory into :
which means :

Is that enough and correct, no config to add or command in cyradm ?

I restarted cyrus but nothing appears in the log directory...

Thank you very much for your help
