最近在学计算机网络看到套接字的练习
于是应用SMTP协议写了个发送邮箱的玩玩
可以发一大堆垃圾邮件给对方
其中参考了
关于发邮件报错535 Error：authentication failed解决方法http://t.csdnimg.cn/Bc0Dq
已经查询如何获取网易邮箱客户端授权码
base64编码

endmsg = "\r\n.\r\n"mailserver = "smtp.163.com"fromaddress = "@163.com"#输入你的163.com邮箱
toaddress = "@qq.com"#输入对方邮箱username = "@163.com"#输入你的邮箱
password = "******"#输入客户端授权码，参考：http://t.csdnimg.cn/Bc0Dqusername_base64 = base64.b64encode(username.encode()).decode()
