cat /root/bin/quota-warning.sh touch /tmp/quota-warning-executed cat /root/bin/quota-exceeded.sh touch /tmp/quota-exceeded-executed
您必须configurationJunk文件夹的配额排除和Trash开销：
plugin { quota = maildir:User quota quota_rule = Junk:ignore quota_rule2 = Trash:storage=+100M quota_warning = storage=50%% quota-warning 50 %u quota_exceeded = storage=100%% quota-exceeded 100 %u }
正如dovecot维基所述，为了避免在转移到Trash发生配额警告，
您可以创build一个单独的配额规则，给予垃圾邮箱稍高的配额限制（但不是无限制）
这是因为转移到Trash是两步程序（复制+删除）。 在短时间内，你有两个相同的消息的副本，他们都是由配额插件计数。 如果Trash有一些开销，则新鲜复制的消息不要超过主限制。 进一步的信息请参阅dovecot的维基： https ： //wiki.dovecot.org/Quota
