邮件帐号管理的shell script

这个shell script是用来操作我的邮服帐号的，现在提供了查看，删除，修改，更新等基本功能。还没有最终完成，比如在部分出错处理时，采用简单忽略的处理方式，数据库的备份和恢复也没加进去呢，删除帐号时也没有提供是否要删除邮件内容的的选择，现在是不删，测试嘛，省的删了又建，麻烦，嘻嘻！有时间再来改吧！真要酬谢我的兄弟p4s2wd啊，前些日子，他发了个在线音乐的网址给我，让我听某个电台，我的firefox无法正常显示，我生气就换成win2000了，我的shell稿子，就这么一生气忘了备份了，呵呵呵，装完系统，补丁更新完毕，重启，啊，win2000起不来了，我晕倒！算了，还是换回来吧！于是又用debian sarge做桌面！这时候才想起来，我的那个脚本没有备份！还好我运气虽然差，还没差到家，呵呵，我记得给我兄弟p4s2wd发过一次，请他斧正的，于是让他又发回给我！他没删噢！哈哈
