用http://www.ziqiangxuetang.com/django/django-send-email.html这里的教程想做个发邮件的demo，一共也没几行代码，但是报错很奇怪，有用过的朋友能帮我看看吗？
settings.py
# send e-mail
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = False
EMAIL_HOST = 'smtp.163.com'
EMAIL_PORT = 25
EMAIL_HOST_USER = 'scmpro@163.com'
EMAIL_HOST_PASSWORD = 'xxxxx'
DEFAULT_FROM_EMAIL = 'scmpro@163.com'
views.py
def ContactUs(request):
send_mail('Subject here', 'Here is the message.', 'scmpro@163.com',
['80746965@qq.com','creabine@foxmail.com'], fail_silently=False)
return render(request,'ContactUs.html')
报错信息为：
SMTPHeloError at /ContactUs.html
(500, b'Error: bad syntax')
折腾好久了，不知道问题在哪里，求指点，谢谢大家
