Hi!

I'm new on Dovecot.
I'm using:
- CentOS 5.5
- Kernel 2.6.18-194.26.1.el5 x86_64
- Dovecot 2.0.8 (from source)
- Postfix 2.7.2 (from source)
- MySQL 5.0.77 (CentOS binary)
- Postfixadmin 2.3.2 (from source)
- Horde Webmail 1.2.9
- Thunderbird 3.1.7 (from CentOS)

I follow this how to: http://wiki2.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL
I was able to send and recieve e-mail via Postfix/Dovecot.

I'm having troubles in the quota.
As I said, I use Postfixadmin to manage users.
When I log in Horde, it says that the quota is unlimited. Thunderbird too.

I think it's because of the configuration on Dovecot.


Here it's my confs files:


=====
dovecot.conf
=====
#ssl_cert_file = /etc/pki/dovecot/certs/myserver.example.com.crt
#ssl_key_file = /etc/pki/dovecot/private/myserver.example.com.key

#default_login_user = nobody

passdb {
  args = /usr/local/dovecot/etc/dovecot/sql.conf
  driver = sql
}
plugin {
  #acl = vfile:/usr/local/dovecot/etc/dovecot/acls
  quota = maildir:storage=10240:messages=1000
  trash = /usr/local/dovecot/etc/dovecot/trash.conf
}
service auth {
  unix_listener auth-userdb {
    group = vmail
    mode = 0660
    user = vmail
  }
  unix_listener auth-master {
    group = vmail
    mode = 0660
    user = vmail
  }
  unix_listener /var/spool/postfix/private/auth {
    group = vmail
    mode = 0660
    user = postfix
  }
  user = dovecot
}
userdb {
  args = /usr/local/dovecot/etc/dovecot/sql.conf
  driver = sql
}
userdb {
  driver = prefetch
}
protocol imap {
  imap_client_workarounds = delay-newmail
  mail_plugins = quota imap_quota
}
protocol pop3 {
  mail_plugins = quota
  pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
}
protocol lda {
  mail_plugins = quota
  postmaster_address = postmaster at mydomain.com
  #log_path = /var/log/dovecot.log
  #info_log_path = /var/log/dovecot.log
}

gid, concat('maildir:storage=', floor(quota/1024)) AS quota FROM
mailbox WHERE username = '%u' AND active = '1'

I think it's it. If I forgot something, please let me know.
