Django 2使用timeweb.ru发送邮件

Question

我检查了ubuntu18.04中没有ufw的Django应用程序 当添加到settings.py时：

EMAIL_HOST = 'smtp.timeweb.ru'
EMAIL_PORT = 465
EMAIL_HOST_USER = 'myemail@timeweb.ru'
DEFAULT_FROM_EMAIL = 'myemail@timeweb.ru'
SERVER_EMAIL = 'myemail@timeweb.ru'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_USE_TLS = True
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

在控制台中运行

python manage.py shell
>>> from django.core.mail import send_mail
>>> send_mail('ddd','fffffffffff', 'myemail@timeweb.ru',['test@gmail.com'],fail_silently=False)

7分钟后，我得到了这个错误

Traceback (most recent call last):
      File "<console>", line 1, in <module>
      File "/home/mikhail/Django/Chapter01/mysite/env/lib/python3.7/site-packages/django/core/mail/__init__.py", line 60, in send_mail
        return mail.send()
      File "/home/mikhail/Django/Chapter01/mysite/env/lib/python3.7/site-packages/django/core/mail/message.py", line 291, in send
        return self.get_connection(fail_silently).send_messages([self])
      File "/home/mikhail/Django/Chapter01/mysite/env/lib/python3.7/site-packages/django/core/mail/backends/smtp.py", line 103, in send_messages
        new_conn_created = self.open()
      File "/home/mikhail/Django/Chapter01/mysite/env/lib/python3.7/site-packages/django/core/mail/backends/smtp.py", line 63, in open
        self.connection = self.connection_class(self.host, self.port, **connection_params)
      File "/usr/lib/python3.7/smtplib.py", line 251, in __init__
        (code, msg) = self.connect(host, port)
      File "/usr/lib/python3.7/smtplib.py", line 338, in connect
        (code, msg) = self.getreply()
      File "/usr/lib/python3.7/smtplib.py", line 394, in getreply
        raise SMTPServerDisconnected("Connection unexpectedly closed")
    smtplib.SMTPServerDisconnected: Connection unexpectedly closed

我做错什么了
