(421, '#4.4.5 Too many connections to this host.')是我邮箱配置的不对？ 还是我没设置什么？
觉得代码没问题啊。

帮你找到两个地方，可以参考参考：

这两个帖子说的都是django跟mysql连接的问题～我怀疑是setting.py中EAMIL配置的问题。或者我选择的新浪邮箱服务器不让这种形式的自动发邮件～<spanstyle="color:#333333;font-family:helvetica,arial,Corbel,Verdana,sans-serif;font-size:14px;line-height:22px;background-color:#FFFFFF;">The“toomanyconnectionsfromyourhost”erroristhetextoftheerrormessagethatiscomingbackfromtheSMTPserver.ItindicatesthattheSMTPserverhasalimitonhowmanysimultaneousopenconnectionsitwillacceptfromasingleIPaddress.Theremusthavebeenotherthreadsorprocesses(orapplications)withopenconnectionstothesameSMTPserverthatcausedyoutoexceedthelimit.

回复<aclass='referer'target='_blank'>@渔樵耕读:试试谢谢！你这段信息很有用啊！难道是因为我昨晚开着新浪邮箱的同时用django发邮件就会报错？@晓骏
我关闭了新浪的邮箱。然后仍然报错～
我把<spanstyle="font-family:微软雅黑,Verdana,sans-serif,宋体;font-size:14px;line-height:22px;background-color:#FFFFFF;">EMAIL_USE_TLS=True这段注释了
<spanstyle="font-family:微软雅黑,Verdana,sans-serif,宋体;font-size:14px;line-height:22px;background-color:#FFFFFF;">就可以发邮件了～
<spanstyle="font-family:微软雅黑,Verdana,sans-serif,宋体;font-size:14px;line-height:22px;background-color:#FFFFFF;">不知道为什么。。。
