Aug  1 15:34:22 mail postfix/smtpd[6062]: fatal: dict_open: unsupported dictionary type: mysql:  Is the postfix-mysql package installed?
 
#解决：apt-get install postfix-mysql
 
#错误3、postfix运行于chroot中
#1）、chroot下，sntpd认证失败，

#在ubuntu下面出现 535 5.7.8 Error: authentication failed: generic failure，基本上是因为postfix chroot造成的
#解决：1、关闭postfix的chroot运行模式。2、换成架构四进行安装，ubuntu团队对此架构做了相关的优化

#优化1：打开extmail邮件系统的web页面加载很慢
#经过分析，发现是由于页面加载时调用了extmail.net的rpc服务。
#解决：
#1)、修改 /var/www/extsuite/extmail/html/plugins/rpc_init.js文件，去除其中rpc的使用.
