# How to force Dovecot to recalculate mailbox quota iRedMail enables dict quota since iRedMail-0.7.0, dict quota is recalculated only if the quota goes below zero * For MySQL and PostgreSQL backend:
mysql> USE vmail;
mysql> DELETE FROM used_quota WHERE username='user@domain.ltd';
* For OpenLDAP backend:
mysql> USE iredadmin;
mysql> DELETE FROM used_quota WHERE username='user@domain.ltd';
Re-login via POP3/IMAP (or webmail) will trigger Dovecot to recalculate mailbox quota. __TIP__: it's safe to delete records in SQL table `used_quota` if mail user was deleted in table `vmail.mailbox` or LDAP. iRedAdmin-Pro will handle this for you automatically.
