Horde vacation displays working but it doesn't

Hi,

I'm using Horde3 webmail for a long time and it works perfectly.

One day, I installed and configured the vacation module with the following vacation config but it doesn't work:

<?php
/* CONFIG START. DO NOT CHANGE ANYTHING IN OR AFTER THIS LINE. */
// $Horde: vacation/config/conf.xml,v 1.15.2.8 2006/10/13 16:03:33 jan Exp $
$conf['vacation']['path'] = '/usr/bin/vacation';
$conf['vacation']['default'] = 'Subject: ' . _("On vacation message") . "\n" . _("I'm on vacation and will not be reading my mail for a while.") . "\n" . _("Your mail will be dealt with when I return.") . "\n";;
$conf['vacation']['subject'] = true;
$conf['vacation']['from'] = true;
$conf['server']['params']['default']['persistent'] = true;
$conf['server']['params']['default']['hostspec'] = 'localhost';
$conf['server']['params']['default']['username'] = 'sql_admin';
$conf['server']['params']['default']['password'] = 'sql_password';
$conf['server']['params']['default']['port'] = 3306;
$conf['server']['params']['default']['protocol'] = 'tcp';
$conf['server']['params']['default']['database'] = 'vhost';
$conf['server']['params']['default']['charset'] = 'iso-8859-1';
$conf['server']['params']['default']['phptype'] = 'mysql';
$conf['server']['params']['default']['table'] = 'users';
$conf['server']['params']['default']['user_col'] = 'email';
$conf['server']['params']['default']['pass_col'] = 'password';
$conf['server']['params']['default']['message'] = 'vacation_msg';
$conf['server']['params']['default']['subject'] = 'vacation_sub';
$conf['server']['params']['default']['vacation'] = 'vacation';
$conf['server']['params']['default']['driverconfig'] = 'custom';
$conf['server']['params']['default']['hordeauth'] = true;
$conf['server']['params']['encryption'] = 'crypt-md5';
$conf['server']['params']['show_encryption'] = true;
$conf['server']['driver'] = 'sql';
$conf['aliases']['show'] = false;
$conf['aliases']['driver'] = 'none';
$conf['user']['refused'] = array('root', 'bin', 'daemon', 'adm', 'lp', 'shutdown', 'halt', 'uucp', 'ftp', 'anonymous', 'nobody', 'httpd', 'operator', 'guest', 'diginext', 'bind', 'cyrus', 'courier', 'games', 'kmem', 'mailnull', 'man', 'mysql', 'news', 'postfix', 'sshd', 'tty', 'www');
$conf['menu']['apps'] = array('horde', 'imp');
/* CONFIG END. DO NOT CHANGE ANYTHING IN OR BEFORE THIS LINE. */

When a user to set the vacation on, the system says: "Failure in modifying vacation notice:"

Then I created 3 columns in users' table manually (vacation,vacation_sub,vacation_msg) even I don't know what the types of them. When set the vacation on, the system says: "Vacation notice successfully enabled."

However, the truth is that it didn't do anything even displayed a successfully message. No auto reply when received mail, no database data changes, no error logging... 

I have no idea how to make it works and solve the problem starting from the beginning since it doesn't have an error word given to me.

Best Regards,
Scs Leo
