## Sending Email
import smtplib
from email.mime.text import MIMEText 

# 第三方SMTP服务
mail_host = 'smtp.126.com'
mail_user = 'example@126.com'
mail_pass = 'password' # 客户端授权密码，非登录密码

sender = 'example@126.com'
receivers = ['example@qq.com']
content = 'Python Send Mail !'
title = 'Python SMTP Mail Test'
message = MIMEText(content, 'plain','utf-8')
message['From'] = '{}'.format(sender)
message['To']=','.join(receivers)
message['Subject'] = title

try:
    smtpObj = smtplib.SMTP_SSL(mail_host, 465)
    smtpObj.set_debuglevel(1) # 解决 500 Error: bad syntax
    smtpObj.ehlo(mail_host) 
    smtpObj.login(mail_user, mail_pass)
    smtpObj.sendmail(sender, receivers, message.as_string())
except smtplib.SMTPException as e:
    print(e)
