通过126邮箱SMTP服务发送邮件到指定邮箱

测试环境清单：smtplib函数库
Python3.7
Windows10
程序源码

import smtplib
from email.header import Header
from email.mime.text import MIMEText
 
# 第三方 SMTP 服务
mail_host = "smtp.126.com"      	# SMTP服务器，需要能够访问外网
mail_user = "lxxxxxxxxxxxx@126.com" #126邮箱用户名
mail_pass = "XVMWJSRBXEQLLLNV"      # 授权密码，非登录密码
 
sender = 'lxxxxxxxxxxxx@126.com'    # 发件人邮箱(最好写全, 不然会失败)
receivers = ['xxxxxxx@qq.com']  # 接收邮件，可设置为目标邮箱
 
content = '2051-10-28 13:41:00 涂装4号车间前处理电泳故障停线12分钟，报交线产量40台'
title = '某某轿车小时停线汇报'  # 邮件主题
 
def sendEmail():
 
    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)
 
def send_email2(SMTP_host, from_account, from_passwd, to_account, subject, content):
    email_client = smtplib.SMTP(SMTP_host)
    email_client.login(from_account, from_passwd)
    # create msg
    msg = MIMEText(content, 'plain', 'utf-8')
    msg['Subject'] = Header(subject, 'utf-8')  # subject
    msg['From'] = from_account
    msg['To'] = to_account
    email_client.sendmail(from_account, to_account, msg.as_string())
 
    email_client.quit()
 
if __name__ == '__main__':
    sendEmail()
    # receiver = '***'
    # send_email2(mail_host, mail_user, mail_pass, receiver, title, content)

首先配置126邮件服务器，步骤如下

1. 网页登录126邮箱，找到邮箱设置
   

2. 找到SMTP配置项
   

3. 开启SMTP服务
   

4. 创建授权码，授权码是用于登录第三方邮件客户端的专用密码
   

5. 手机扫描二维码发送短信完成验证，点击我已发送就可以创建新的授权码
   

6. 生产的授权码要保存好，只能看一次，永久有效
   

7. 修改python程序，需要修改登录用户、授权码、源邮箱、目标邮箱、邮件内容等
   

8. 测试发送邮件到目标邮箱
   运行python程序（需要连接外网）

9. 大功告成
