quota主要由dovecot实现

实现对邮件服务器中用户的quoto设置

/etc/dovecot/dovecot.conf
protocol imap {
  mail_plugins = quota imap_quota
}
protocol pop3 {
  mail_plugins = quota
}
# In case you're using deliver:
protocol lda {
#quota插件和邮件自动分类进入文件夹或删除插件
  mail_plugins = quota cmusieve
}

plugin {
  # 10 MB + 1000 messages quota limit
  #可以被单独用户大小覆盖
  quota = maildir:storage=1024000000:messages=0
}

#userdb static  注销这个静态的
使用动态的
userdb sql {
    # Path for SQL configuration file, see /etc/dovecot/dovecot-sql.conf for example
    args = /etc/dovecot/dovecot-sql.conf
}

/etc/dovecot/dovecot-sql.conf

user_query = SELECT '/home/vmail/%d/%n' as home, 5566 AS uid, 5566 AS gid,

concat('maildir:storage=', floor(quota/1024)) AS quota FROM view_users WHERE email = '%u'
