[Dovecot] quota and dict quota

[Osvaldo Alvarez Pozo]

Hi I am running dovecot  with quota. as show in this part of dovecot.conf
.
protocols = imap pop3
protocol imap {
  mail_plugins = quota imap_quota
  imap_client_workarounds = outlook-idle delay-newmail
}
protocol pop3 {
  mail_plugins = quota
  pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
  pop3_uidl_format = %08Xu%08Xv
}
protocol lda {
  mail_plugins = quota
  log_path = /var/log/dovecot-deliver.log
  info_log_path = /var/log/dovecot-deliver.log
}

Now  I want to see the users's use of quota in postfixadmin, wich
demende the use of dict quota. That is wath I do not understang.

Can I have dict quota and mail_plugins=quota  at the same time?

How do I do?

Thanks
