[Dovecot] Quota won't work

[Markus Fritz]

I tried to set a quota setting. I installed dovecot with newest 
version, patched it and started it.
dovecot -n:

     master:
       path: /var/run/dovecot/auth-master
       mode: 384
       user: vmail

/etc/dovecot/dovecot-sql.conf:


driver = mysql
connect = host=127.0.0.1 dbname=mailserver user=mailuser 
password=******
default_pass_scheme = PLAIN-MD5
password_query = SELECT email as user, password FROM virtual_users 
WHERE email='%u';
user_query = SELECT CONCAT('/var/mail/', maildir) AS home, 
CONCAT('*:bytes=', quota) AS quota_rule \
  FROM virtual_users WHERE email='%u'


virtual_users has this:

CREATE TABLE IF NOT EXISTS `virtual_users` (
   `id` int(11) NOT NULL AUTO_INCREMENT,
   `domain_id` int(11) NOT NULL,
   `password` varchar(32) NOT NULL,
   `email` varchar(100) NOT NULL,
   `quota` int(11) NOT NULL DEFAULT '629145600',
   PRIMARY KEY (`id`),
   UNIQUE KEY `email` (`email`),
   KEY `domain_id` (`domain_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8;

Also postfix is installed with this (not the hole cfg):

virtual_mailbox_domains = 
mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf
virtual_mailbox_limit_inbox = no
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql-quota.cf
virtual_mailbox_limit_override = yes
virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
virtual_maildir_extended = yes
virtual_maildir_limit_message = "The user you are trying to reach is 
over quota."
virtual_maildir_limit_message_maps = mail:/etc/postfix/mysql-quota.cf
virtual_overquota_bounce = yes

/etc/postfix/mysql-quota.cf:

user = mailuser
password = ******
hosts = 127.0.0.1
dbname = mailserver
query = SELECT quota FROM virtual_users WHERE email='%s'


I changed the quota of my mail account to 40, so 40Byte should be the 
maximum.
My account is at a size of 600KB now. I still recieve mails, also they 
will be saved without errors.

/var/log/mail.log says nothing to quota, just normal recieve and store 
entries.

What to fix?
