+# 在邮箱配额中忽略垃圾箱目录
+
+在 Dovecot 中每用户邮箱配额规格是由以下列明的其中一个配置文件决定的：
+
+* `/etc/dovecot/dovecot-mysql.conf`: MySQL 后台
+* `/etc/dovecot/dovecot-pgsql.conf`: PostgreSQL 后台
+
+如果没有进行找到每用户邮箱配额设置， Dovecot 将会调用 `/etc/dovecot/dovecot.conf` 文件中的 'quota_rule[X]' 参数来替代，例如：
+
+```
+# File: /etc/dovecot/dovecot.conf
+
+plugin {                                                                        
+
+    quota = dict:user::proxy::quotadict
+    quota_rule = *:storage=1G
+    #quota_rule2 = *:messages=0
+    #quota_rule3 = Trash:storage=1G
+    #quota_rule4 = Junk:ignore
+
+    ...
+}
+```
+
+因此，要忽略配额中的 `Trash` 目录，你可以在 `/etc/dovecot/dovecot.conf` 或者 `/etc/dovecot/dovecot-{mysql,pgsql,ldap}.conf` 中增加新的配额规则（quota_rule）。
+
+* 示例设置 #1:
+
+```
+# File: /etc/dovecot/dovecot.conf
+
+plugin {                                                                        
+
+    quota = dict:user::proxy::quotadict
+    quota_rule = *:storage=1G
+    quota_rule2 = Trash:ignore
+
+    ...
+}
+```
+
+* 示例设置 #2:
+
+```
+# File: /etc/dovecot/dovecot-ldap.conf
+user_attrs      = ...,mailQuota=quota_rule=*:bytes=%$,=quota_rule2=Trash:ignore
+
+# File: /etc/dovecot/dovecot-mysql.conf, or dovecot-pgsql.conf
+user_query = SELECT ... \
+                   CONCAT('*:bytes=', mailbox.quota*1048576) AS quota_rule \
+                   'Trash:ignore' AS quota_rule2 \
+                   FROM ...
+```
