关于postfix 与dovecot sasl 认证问题

luofeg

各位大师：
   本人自建一台centos6.5 +postifx2.66+dovecot2.09+saslauthd2.13+mysqld5.1+php5.6w+httpd+postadmin2.93 做邮件服务器，现需到如下问题 ，本人折腾了快两周了，实现水平有限，特发贴请高手赐教？？？？？？？？？
以下为报错LOG（*号本人屏蔽了）

本人搭建服务器方法，完全是按照本教程操作  https://www.ilanni.com/?cat=936

如果把postfix  配置文件mail.cf中的  smtpd_sasl_type = dovecot  给注释掉，各功能都正常，如果注释了就没有启用认证功能。

下面是本面的配置

还有我在网上查了好问相关类似问题回答，做软链接也做了，以上软件除了postfixadmin编译安装，其于均用yum安装。
