 原来一直在用thunderbird，用的也不错，不过gnus也很方便，呵呵

 版本
 emacs23 ，gnus目前是emacs自带的但是一直无法收邮件，所以去主页下了个最新的，
 配置成功，可以收发gmail.

 下载后解压 ./configure&make  ,之后我把此文件夹放到.emacs.d/site-lisp，这个
  自己可以随意放，下面目录对应就可以了

 在.emacs中加入
 (setq load-path (cons (expand-file-name "~/.emacs.d/site-lisp/ngnus-0.6/lisp")
load-path))
(require 'gnus-load)

 创建自己的~/.gnus.el,其实也可以放在.emacs中，但是建议分开来
 内容如下
