由于公司的审计邮箱在windows下运行一直不太稳定，为此我将邮箱移植到linux Iredmail下(具体的Iredmail安装方法我就不过多介绍文档很多)，我们的用户名和密码都是如下形式

test1:123456
test2:234566
但是我们有将近2万的用户需要导入，于是问了一下Iredmail的管理员批量导入用户的问题，得知只可以批量创建用户但是没有批量导入用户名和密码这个功能。于是就找到了批量创建用户的脚本，做了修改，可以成功实现想要的功能，具体脚本如下:
这里说明一下这个脚本的原作者是Zhang Huangbin，我是做了二次功能修改实现的。(这脚本执行过后就生成了一个output.sql文件里面是所有用户的标准SQL语句,你只需执行导入到相应的库里就可以了)
