我的Dovecot安装不会覆盖userdb的quota_limit。 我已经证实，它已经成功连接到我的Mysql数据库，但我的配额限制仍然停留在默认的100MB。 难道我做错了什么？
Dovecot.conf ==================================================== mail_plugins = $mail_plugins quota passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = $mail_plugins imap_quota } protocol lmtp { mail_plugins = quota fts sieve } protocol lda { mail_plugins = quota } plugin { quota = maildir quota_rule = *:storage=100M quota_rule2 = Trash:storage=+10%% } service auth-worker { user = vmail } service dict { unix_listener dict { mode = 0660 user = vmail group = vmail } } auth_debug = yes auth_debug_passwords = yes auth_verbose = yes mail_debug =yes dovecot-sql.conf.ext ==================================================== driver = mysql connect = host=127.0.0.1 dbname=****SNAP**** user=****SNAP**** password=****SNAP**** default_pass_scheme = SHA256-CRYPT password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; default_pass_scheme = SHA256-CRYPT user_query = SELECT CONCAT('*:bytes=', quota) as quota_rule FROM virtual_users WHERE email = '%u' 尝试在userdbconfiguration之前移动配额插件。 大多数configuration都是自上而下处理，最后一个值得胜。
