使用python自动发邮件(163、QQ、outlook邮箱)

import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr
from datetime import datetime
 
# 发件人邮箱账号
my_sender = "l1525943131@163.com"
# my_sender = "1525943131@qq.com"
# 收件人邮箱账号
my_user = ["1525943131@qq.com"]
# my_user = ["l1525943131@163.com"]
# 授权码，不是账号的密码
authorization_code = "********"
# authorization_code = "****************"
# 发送人姓名
sender_name = "After__today"
# 接收人姓名
user_name = ["天晴的时候会下雨"]
# 发件服务器
smtp = "smtp.163.com"   #网易163
# smtp="smtp.qq.com"    #qq邮箱
 
def mail(text):
    now_time = datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    ret = True
    for i in range(len(my_user)):
        text1 = "您好 "+user_name[i]+"
现在时间为"+str(now_time)+"
很抱歉打扰您！

        try:
