# 參數(shù)介紹  
# subject: 郵件主題 
# message: 郵件內(nèi)容 
# from_email: 發(fā)件人 
# recipient_list: 收件人，這是一個(gè)列表，可以有多個(gè)收件人 
# 以上4個(gè)在參數(shù) 在send_mass_mail中，會(huì)寫在datatuple這個(gè)元組中 
# fail_silently: 是否報(bào)錯(cuò)，True的話表忽略異常 
# auth_user&auth_password:賬號(hào)密碼 
# connection: 表示這個(gè)的鏈接對(duì)象，后續(xù)會(huì)提到 
# html_message: send_mail方法獨(dú)有，可以比較簡(jiǎn)單地實(shí)現(xiàn)一個(gè)html文本的傳輸，具體我也沒使用過，不是很了解。
