Question

views.py

from django.core.mail import send_mail
def send(request):
    subject = 'hi'
    message = 'hello'
    from_emaill = 'chidanandanayak06@gmail.com'
    recipiant_list = ['chidanandanayak06@gmail.com','shuryansh.hot@gmail.com']

    send_mail(subject,message,from_emaill,recipiant_list)
    return render(request,'mail.html')

urls.py

path('mail/',views.send, name= 'sendmail')

我的服务器

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'chidananda'
EMAIL_HOST_PASSWORD = '**********'
EMAIL_POST = 587
EMAIL_USE_TLS = True

我不知道为什么异常断开连接！同样的事情也发生在另一个项目上。
