# 在邮箱配额中忽略垃圾箱目录
|
||
|
||
在 Dovecot 中,针对单个用户的邮箱配额限制定义在下列文件之一:
|
||
|
||
* `/etc/dovecot/dovecot-mysql.conf`: MySQL 后端
|
||
* `/etc/dovecot/dovecot-pgsql.conf`: PostgreSQL 后端
|
||
|
||
如果没有针对单个用户的邮箱配额限制,Dovecot 将使用 `/etc/dovecot/dovecot.conf`
|
||
文件中的 `quota_rule[X]` 设置。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 `Trash` 目录的邮箱容量,可以在 `/etc/dovecot/dovecot.conf` 或
|
||
`/etc/dovecot/dovecot-{mysql,pgsql,ldap}.conf` 中增加新的配额规则(quota_rule)。
|
||
|
||
* 配置示例 1:
|
||
|
||
```
|
||
# File: /etc/dovecot/dovecot.conf
|
||
|
||
plugin {
|
||
|
||
quota = dict:user::proxy::quotadict
|
||
quota_rule = *:storage=1G
|
||
quota_rule2 = Trash:ignore # <- 新配额规则:忽略 Trash 目录
|
||
|
||
...
|
||
}
|
||
```
|
||
|
||
* 配置示例 2:
|
||
|
||
OpenLDAP 后端:
|
||
```
|
||
# File: /etc/dovecot/dovecot-ldap.conf
|
||
|
||
user_attrs = ...,mailQuota=quota_rule=*:bytes=%$,=quota_rule2=Trash:ignore
|
||
```
|
||
|
||
MySQL 或 PostgreSQL 后端:
|
||
# 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 \ -- 新配额规则:忽略 Trash 目录
|
||
FROM ...
|
||
```
