主题: 邮件队列显示 (temporary failure)，公司员工只能发邮件不能收邮件
您好，张工，麻烦您帮忙分析一下问题出现哪里？谢谢。
iRedOS 版本：集成在CentOS上的IRedOS 0.6.0
故障现象：
1、发邮件正常，无法收邮件
2、postqueue -p中以看到邮件队列里所有入站邮件后边显示 (temporary failure)，postqueue -f之后显示同样的字符
3、通过http://mail.server.com/mail能打开WEB Mail页面，但是不能登录
4、amavisd、clamd、dovecot、postfix、httpd、mysqld等服务均能正常启动
5、vi /var/log/dovecot.log，提示有pop3的fatal failure，Log信息如下：
