做了一个html E-Letter项目.
邮件模板采用jinja2, html 邮件内容生成简直太爽了.
整个项目开发只用了2个小时, 调试却花了大半天时间, 生成的邮件总是发不出去.
于是, 打开 smtp 的debuglevel, 发现邮件已经mail queue了, 但就是收不到邮件. mail server是exchange. 之前用java写过类似的程序也没有问题(也是走smtp协议发送html邮件). 为什么这次用python实现却有问题?
怀疑过python smtp模块用法, 怀疑过python smtp的html写法, 怀疑过smtp subject和content不支持unicode. 最终都被排除.
最后终于定位到元凶: 邮件的subject只要包含"Please check."这13个字符, 邮件就会石沉大海. 难道是exchange server设了某种规则?

代码结构
#------------------
下面简单描述一下项目的结构, 在我的脚手架项目基础上, 做了少量的裁剪, 并增加两个目录, scripts和templates, scripts目录存放E-Letter生成和发送脚本, templates目录存放E-Letter的模板.
并附上 mail_service.py, 修改了网上找的代码, 用来发送 html 邮件.
