mail - Python通过SMTP发送邮件总是验证失败。

Question

以下是我的代码及返回信息，163和qq的都尝试过但都是验证错误，密码什么的我肯定是没有输错的。
代码：

#-*- encoding: utf-8 -*-
import os, sys
import smtplib
from smtplib import SMTP_SSL
from email.header import Header
from email.mime.text import MIMEText
 
mailInfo = {
    "from": "xxx@qq.com",
    "to": "yyy@163.com",
    "hostname": "smtp.qq.com",
    "username": "xxx@qq.com",
    "password": "*********",
    "mailsubject": "this is test",
    "mailtext": "hello, this is send mail test.",
    "mailencoding": "utf-8"
}
         
if __name__ == '__main__':
    smtp = SMTP_SSL(mailInfo["hostname"])
    smtp.set_debuglevel(1)
    smtp.ehlo(mailInfo["hostname"])
    smtp.login(mailInfo["username"],mailInfo["password"])
     
    msg = MIMEText(mailInfo["mailtext"],"text",mailInfo["mailencoding"])
    msg["Subject"] = Header(mailInfo["mailsubject"],mailInfo["mailencoding"])
    msg["from"] = mailInfo["from"]
    msg["to"] = mailInfo["to"]
    smtp.sendmail(mailInfo["from"], mailInfo["to"], msg.as_string())
     
    smtp.quit()

返回错误：

拜托大家帮忙解决下我的问题！！！

Answer 1

哥们，说的很清楚了，登陆验证失败，一般来说，是因为没有开启SMTP服务。

我关闭了服务，和你的报错一样的。

重新打开这个服务，就成功。具体的打开方法网上可以搜索到，一般是在账户里面设置。

附我成功的截图和log

Answer 2

亲,我刚刚试了下,在终端里设置密码时,需要的不是个人密码,而是网易的授权码.
短信里都说了,都没有仔细看....

Answer 3

你好，为什么我发送出去的邮件的正文是空的？

Answer 4

谢谢 韦轩 的回答，差点把这个问题给忘了，当初一直出错是因为多年前就把qq smtp服务打开了，不知道后来qq跟163一样开启smtp服务也要设置独立密码。当关闭smtp服务再重新开启并设置密码就没问题了。

Answer 5

要用客户端授权码代替密码
