[Dovecot] problem mysql and dovecot 1.2

[debian at robertain.com]

Hi everybody , 

Since my version 1.2. I have a problem with the management of quotas.


select * from virtual_users;
+----+-----------+----------------------------------+---------------------------+----------+----------------+
| id | domain_id | password                         | email               
    | quota_kb | quota_messages |
+----+-----------+----------------------------------+---------------------------+----------+----------------+
|  1 |         1 | xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx | xxxxxx at domain.com  
    | 10000000 |              0 |
..................

Before my time in 1.2. I did this for the quota management:
user_query = SELECT
CONCAT('/var/vmail/',CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1)))
AS home, 5000 AS uid, 5000 AS gid,
CONCAT('maildir:storage=',quota_kb,':messages=',quota_messages) AS quota
FROM virtual_users WHERE email='%u';

#user_query = SELECT home, uid, gid, concat('*:storage=', quota_bytes,
'B') AS quota_rule FROM virtual_users WHERE userid = '%u'
#user_query = SELECT maildir, 5000 AS uid, 5000 AS gid,
CONCAT('*:storage=', quota_bytes, 'B') AS quota_rule FROM virtual_users

#user_query = SELECT maildir AS home , 5000 AS uid, 5000 AS gid,
CONCAT('*:storage=',quota, 'B') AS quota_rule FROM virtual_users WHERE
username = '%u' 
#user_query = SELECT maildir AS home, 5000 AS uid, 5000 AS gid,
CONCAT('*:bytes=', CAST(quota AS CHAR)) AS quota_rule FROM quota WHERE
username = '%u' AND active = '1

I used all these configurations but none work.

yet but the quotas work through this option:
quota_rule: *:storage=100M
The problem is that quotas are not personalized.

I'm looking for a way to use quotas, but using my mysql database. I galley
for some time.
So if someone has an idea I am willing
