   我将代码中我的邮箱和密码都隐藏了，如果大家要试验的话，请换成自己的邮箱和密码，记住这个密码不是登录密码，而是开启smtp时输入的管理密码。
   mail核心代码：
1.首先配置smtp服务器:

#下面是SMTP服务器配置
app.config['MAIL_SERVER'] = 'smtp.163.com' #电子邮件服务器的主机名或IP地址
app.config['MAIL_PORT'] = '25' #电子邮件服务器的端口
app.config['MAIL_USE_TLS'] = True #启用传输层安全
app.config['MAIL_USERNAME'] ='xxxxxx@163.com' #os.environ.get('MAIL_USERNAME') #邮件账户用户名
app.config['MAIL_PASSWORD'] = 'xxxxxx'#os.environ.get('MAIL_PASSWORD') #邮件账户的密码

msg = Message(styledata,sender='xxxxxx@163.com',recipients=[receiverName])#发件人，收件人
msg.body = bodydata
mail.send(msg)
