Linux Mail Server Setup and Howto Guide

Hi,

I followed your tutorial in http://www.linuxmail.info/mult…..-centos-5/

but when i restart dovecot, i get error like this:

# service dovecot restart
Stopping Dovecot Imap:                                     [FAILED]
Starting Dovecot Imap: Error: Error in configuration file /etc/dovecot.conf line 967: Unknown setting: user
Fatal: Invalid configuration in /etc/dovecot.conf
                                                           [FAILED]

I see in my dovecot.conf, in line 967 there is:

user = root

i changed user to vmail but  i get the same error.

Thank You foryour answer  .

So, what should i do?
