Force Dovecot to recalculate mailbox quota

Dovecot-2.x

Dovecot provides command line tool doveadm to recalcuate mailbox quota. Sample usage:

Recalculate one mailbox:

doveadm quota recalc -u user@domain.ltd

Recalculate ALL mail accounts:

doveadm quota recalc -A

Reference: Doveadm-Quota

Dovecot-1.x and Dovecot-2.x

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.
