上文的理论知识过后, 动手验证邮件收发流程。事先试验过，板子上的python是2.7的，所以我也特地下载了python2.7在我的开发主机上。关于版本一定要注意。python3在桌面开发上成主流了。不过很多嵌入式环境都只支持python2的版本。为了开发效率，最好在桌面上也使用python2来开发验证，到了开发板就不会再来一次移植.关于python2, python3之间的恩怨差别等等，请参考这个连接：我就不详叙了。后面提到的python都是说的python2.
给纠结python2与python3的人看的连接

先来试验python发邮件， python就有一个smtplib管这事情的，所以相对简单，但是板子上面的python2缺少email这个package, 这个package用来管理email信息组织的。我采取了简单的解决方案：
直接把桌面python2的email相关的.py文件给copy到板子的/usr/lib/python2.7/路径，因为python的特点就是代码级别的跨平台。所以还真解决了我的问题。当然这不是解决问题的正确的方法，道德高尚的人应该重新编译内核才对。我暂且这么用着吧。参考的连接是：
Python smtplib 参考
上代码：

注意用户名密码我修改了，你们要用得改成你们自己的。smtp的地址也的相应修改。

再来imap的收邮件, python中也有个package叫做imaplib
文档在python官网上找,imap的部分我参考了sina博客上面的一个同学的代码，但是现在搜索不到了,所以没法给连接了，代码中有他名字
代码分两部分：
checkMail.py

老规矩，用户名密码我隐去了。

这两个过程我都在host机器上搞通了。又下载到板子上运行通过了。除了上面年说的email缺失之外，host与开发板子上几乎无区别.

下一篇介绍交叉编译C语言程序的过程。python毕竟只能验证过程与原理.
