     # stmp 发送邮件. 发现群发地址用‘，’相隔的字符串，只有一个成功，所以改用列表。
    smtp.sendmail(paramMap[ " from " ], FinallyAdd, msgRoot.as_string())
    smtp.quit()
     return  True

# ===Test =========================================
if   __name__   ==   ' __main__ '  :
    
     from  mailconf  import  mailmap
    sendmail(mailmap)

    发信信息是可以乱写的。而真正和stmp有密切关系的是 ：smtp.sendmail(paramMap["from"], FinallyAdd, msgRoot.as_string())
    也就是上面的什么发信人地址 ，收信人地址 ，抄送人地址都可以是假的。
