Dovecot ignores maildirsize file (quota)

[radarino]

I'm using postfix with maildrop as lda and dovecot as imap/pop3 server, and I'm trying to set user quota.
Maildirsize file (Maildir++ format) is ignored by dovecot. My dovecot.conf has:

protocol imap {
...
  mail_plugins = quota imap_quota
  mail_plugin_dir = /usr/lib/dovecot/modules/imap
...
}

plugin {
 quota = maildir
 ...
}

but maildirsize file (correctly used by maildrop) is not read (or update) by dovecot.

I'm using Ubuntu server (Release: 9.10), dovecot_common 1:1.1.11-0ubuntu11

Solved!
This is not a bug.. in default configuration (in /etc/dovecot/dovecot-sql.conf), user_query looks like:

user_query = SELECT '/var/vmail/%d/%n' as home, \
'maildir:/var/vmail/%d/%n' as mail,
concat('dirsize:storage=', quota) AS quota,
150 AS uid, 8 AS gid FROM mailbox WHERE username = '%u' AND active = 1

but in this way quota are managed via "dirsize" backend (not "maildir" backend)!!
Removing "quota" from query all seems to work!

Thanks,
