Python SMTP 163邮箱发送邮件不成功

新的教程，可以成功发送(Python3)

import smtplib
from email.mime.text import MIMEText

# 第三方 SMTP 服务
mail_host = "smtp.163.com"  # SMTP服务器
mail_user = "username"  # 用户名
mail_pass = "passwd"  # 密码

sender = '[email protected]'  # 发件人邮箱(最好写全, 不然会失败)
receivers = ['[email protected]']  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱


content = '过期教程害死人!'
title = 'Python SMTP Mail Test'  # 邮件主题
message = MIMEText(content, 'plain', 'utf-8')  # 内容, 格式, 编码
message['From'] = "{}".format(sender)
message['To'] = ",".join(receivers)
message['Subject'] = title

try:
    smtpObj = smtplib.SMTP_SSL(mail_host, 465)  # 启用SSL发信, 端口一般是465
    smtpObj.login(mail_user, mail_pass)  # 登录验证
    smtpObj.sendmail(sender, receivers, message.as_string())  # 发送
    print("mail has been send successfully.")
except smtplib.SMTPException as e:
    print(e)
    

发送结果如图:
