+# How to ignore Trash folder in mailbox quota
+
+Quota\_rule is overrode in `/etc/dovecot/dovecot-mysql.conf` or `/etc/dovecot/dovecot-ldap.conf`, so please change them instead. If no per-user quota rules found, Dovecot will use 'quota_ruleX' in dovecot.conf.
+
+For example, with OpenLDAP backend, you have `/etc/dovecot/dovecot-ldap.conf`, update it with 'Trash:ignore' like below:
+
+<pre>
+user_attrs      = ...,mailQuota=quota_rule=*:bytes=%$,=quota_rule2=Trash:ignore
+</pre>
+
+With MySQL backend, update `/etc/dovecot/dovecot-mysql.conf`:
+
+<pre>
+user_query = SELECT ... \
+                   CONCAT('*:bytes=', mailbox.quota*1048576) AS quota_rule \
+                   'Trash:ignore' AS quota_rule2 \
+                   FROM ...
+</pre>
