dovecot 设置邮箱quota

大家好，又见面了，我是你们的朋友全栈君。

先按照 下面启用quota

conf.d/10-mail.conf:

# Space separated list of plugins to load for all services. Plugins specific to
# IMAP, LDA, etc. are added to this list in their own .conf files.
mail_plugins = $mail_plugins quota

复制

conf.d/20-imap.conf:

protocol imap {
  # Space separated list of plugins to load (default is global mail_plugins).
  mail_plugins = $mail_plugins imap_quota
}

复制

conf.d/90-quota.conf:

plugin {
  #quota = dirsize:User quota
  quota = maildir:User quota
  #quota = dict:User quota::proxy::quota
  #quota = fs:User quota
  quota_exceeded_message = Quota exceeded(对方邮箱空间不足), please go to http://www.example.com/over_quota_help for instructions on how to fix this.
}

复制

最后修改 dovecot-sql.conf.ext 里面用户查询信息

user_query = \
  SELECT maildir as home, 889 AS uid, 889 AS gid ,\
  concat('*:bytes=',quota) AS quota_rule\
  FROM mailbox \
  WHERE name = '%n' AND domain = '%d'

password_query = SELECT CONCAT(name, '@', domain) AS user, \
  passwd AS password ,concat('*:bytes=',quota) AS userdb_quota_rule\
  FROM mailbox \
  WHERE name = '%n' AND domain = '%d'

复制

注意 ‘maildir:’,quota 是配置文件 90-quota.conf里面的 对应quota = maildir:User quota

如果是修改方式限制quoto则作相应的修改。
