webmin 的mailscanner 安装后存在的问题

Webmin version 1.410
mailscanner的webmin模块版本是：webmin-module-1.1-4.wbm

在webmin里安装好做了如下配置：

Full path to MailScanner program:                          /usr/sbin/MailScanner
Full path and filename of MailScanner config file:    /etc/MailScanner/MailScanner.conf
Full path to the MailScanner bin directory:              /usr/sbin/
Full path and filename for the MailScanner pid file: /var/run/MailScanner.pid
Command to start MailScanner:                              /etc/init.d/MailScanner start
Command to stop MailScanner:                              /etc/init.d/MailScanner stop

但是配置好后仍然出现如下错误：
MailScanner has not been configured correctly. You must use the module configuration to set it before this module will work.
不知哪为高手有过配置成功的经历，老的版本不需要这样配置，只要配前两个选项就可以了
