Python实现邮件发送的详细设置方法(遇到问题)

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart   

def sendMail(msg):
	#发送邮件的邮箱
  sender = '2399958750@qq.com'
  #接受邮件的邮箱
  to_list = [
  	'676482793@qq.com'
  ]
  subject = 'Hello Mail'

  # 创建邮箱
  em = MIMEMultipart()
  em['subject'] = subject
  em['From'] = sender
  em['To'] = ",".join(to_list)

  # 邮件的内容
  content = MIMEText(msg)
  em.attach(content)

  # 发送邮件
  # 1、连接服务器
  # 25端口已经被云服务器商关闭了，所以只能用465端口了
  smtp = smtplib.SMTP_SSL('smtp.qq.com\或者是smtp.163.com', 465)
  # 2、登录
  smtp.login(sender, "授权码或者邮箱密码")
  print("登录服务器成功")
  # 3、发邮件
  smtp.send_message(em)
  print("发送邮件成功")
  # 4、关闭连接
  smtp.close()

if __name__ == "__main__":
  sendMail('Hello Mail！My name is stylle')
