''构思时用的freemind图在[[QiangningHong/2005-07-25]]。''

== 使用方法 ==

解压后用浏览器（推荐[[http://www.spreadfirefox.com/?q=affiliates&id=67907&t=1|Firefox]]）打开maillist.html即可。

== 用到的统计邮件列表中MUA使用情况的小程序 ==

写的很烂 //blush 不过应该不会算错;)

用mbox文件的文件名作参数，我是直接用的[[http://www.mozilla.org/products/thunderbird/|Thunderbird]]的文件。
