Python SMTP配置参数并发送邮件

import smtplib

from email.mime.text import MIMEText
from email.header import Header

sender = '973708513@qq.com' # 发送方
receiver = 'sutaoyu001@163.com' # 接收方

# 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码
message = MIMEText('QQ像163发送测试文件....','plain','utf-8')
message['From'] = Header('Python教程...') # 发送者
message['To'] = Header('测试','utf-8')   # 接受者

subject = 'Python SMTP测试'
message['subject'] = Header('utf-8')

try:
  smtpObj = smtplib.SMTP('localhost')
  smtpObj.sendmail(sender, receiver, message.as_string())
  print("邮件发送成功")
except smtplib.SMTPException:
  print("Error: 无法发送邮件")

# 邮件发送成功

import smtplib

from email.mime.text import MIMEText
from email.header import Header

#第三方SMTP服务
