[Dovecot] Quota is not working (Debian Squeeze - Dovecot 1.2)

[RaSca]

Hi all,
I'm trying to make quota work in Squeeze (Dovecot 1.2.15-7).
The quota module is correctly loaded and, when receiving a message, from
the log I see these messages:

Now, since I've got a message like this:

Quota root: name=/mail/mailboxes/<mydomain>/testquota@<mydomain>
backend=maildir args=

it seems that something is checked, but even if this directory is over
quota, nothing happens.

This is my dovecot conf:

protocols = imap pop3
disable_plaintext_auth = no
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/mail/mailboxes/%d/%n@%d
mail_privileged_group = mail
mail_debug = yes
mail_nfs_storage = yes
mmap_disable=yes
fsync_disable=no
mail_nfs_index = yes

protocol imap {
  mail_plugins = quota imap_quota
}

protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
  mail_plugins = quota
}

protocol managesieve {
}

protocol lda {
    auth_socket_path = /var/run/dovecot/auth-master
    postmaster_address = postmaster@<mydomain>
    mail_plugins = sieve quota
    quota_full_tempfail = no
    log_path =
}

auth default {
  mechanisms = plain
  passdb sql {
    args = /etc/dovecot/dovecot-sql.conf
  }
  userdb passwd {
  }
  userdb static {
    args = uid=5000 gid=5000 home=/mail/mailboxes/%d/%n@%d
allow_all_users=yes
  }
  user = root
   socket listen {
    master {
        path = /var/run/dovecot/auth-master
        mode = 0600
        user = vmail
    }
    client {
        path = /var/spool/postfix/private/auth
        mode = 0660
        user = postfix
        group = postfix
    }
   }
}

plugin {
  quota = maildir:/mail/mailboxes/%d/%n@%d
  sieve_global_path = /mail/sieve/globalsieverc
}

The db connection works, this is /etc/dovecot/dovecot-sql.conf:

driver = mysql
connect = host=<myserver> dbname=mail user=<myuser> password=<mypassword>
default_pass_scheme = CRYPT
password_query = SELECT username, password FROM mailbox WHERE username='%u'
user_query = SELECT username AS user, maildir AS home,
CONCAT('*:storage=', quota , 'B') AS quota_rule FROM mailbox WHERE
username = '%u' AND active = '1'

and for the user testquota the user_query results in this:

+-------------------+----------------------------+--------------------+
| user              | home                       | quota_rule         |
+-------------------+----------------------------+--------------------+
| testquota@<mydom> | <mydom>/testquota@<mydom>/ | *:storage=1024000B |
+-------------------+----------------------------+--------------------+

everything else is ok, for example I'm using sieve for the spam filter,
and the SPAM is correctly put in the .SPAM dir.

I turned on debug on dovecot, but I can't see if the query in some way
fails.

Can you please help me to understand what am I doing wrong?
