通過Python群發郵件並支持模板

需求：

公司使用SVN，建立用戶，密碼，分配權限，為了保證安全性，密碼隨機生成並通過郵件發送給每個人

資源：

1、會一份表格，中有如下字段：

mail, passwd, name, team, rank

郵箱，密碼，姓名，部門，職位

2、郵件的模板：

%s，您好：
系統為您分配了SVN用戶名和密碼
用戶名:%s(即您的郵箱地址)
密 碼:%s(系統自動分配，不能修改，系統將定期修改並發郵件給大家)

....

主要要帶進去，姓名，郵箱地址，密碼

上代碼：

1. #! /usr/bin/env python
2. # -*- coding: utf-8 -*-
3. #@author [email protected]
4. #@version 2012-02-22 09:20
