Courier-imap

[Dalibor]

Instaliral sem courier-imap in mi pri logiranju v log file napiše:
Jul 21 12:31:51 localhost authdaemond.mysql: failed to connect to mysql 
server (server=mysql.example.com, userid=admin)
Jul 21 12:31:56 localhost imapd: LOGIN FAILED, ip=[::ffff:xxx.xxx.xxx.xxx]
Jul 21 12:31:56 localhost imapd: LOGOUT, ip=[::ffff:xxx.xxx.xxx.xxx]

Seveda nočem imeti nič z mysql bazo ampak naj mi courier preveri userja 
v /etc/passwd. Kje to nastavim?
