1.访问http://IP/postfixadmin/setup.php
2.创建Setup password(如:123456)
  点击“Generate password hash”获取一段加密代码
  将该代码拷贝到配置文件config.inc.php中的以下配置中
  $CONF['setup_password'] = 'change';(用加密代码替换change)
  然后再次访问PostfixAdmin的设置页,创建管理员的账号和密码
  (需要正确输入之前创建的Setup password才能创建管理员账号)
3.访问PostfixAdmin的登录页http://IP/postfixadmin/
  使用管理员账号登录后,就可以进行相应的管理工作.
