Currently I have an Exchange server running and am attempting to run send_mail, though get a variety of errors.
Here is my current settings.py
EMAIL_HOST = 'exchange.domain.com'
EMAIL_HOST_USER = 'DOMAIN\user'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_PORT = 443
EMAIL_USE_TLS = True
and when I run send_mail('''Subject''', '''Message.''', 'myemail#domain.com', ['otheremail#domain.com',], fail_silently=False)
after a very long wait

I used Celery for email registration asynchronously, but when I trigger this asynchronous request, the following error will appear

There is no problem with the celery tasks code, because I was able to use it before, but the above situation appeared after I changed a computer

When I searched for a few days, I determined the BUG location, it turned out that the eventlet and dnspython modules were incompatible, and I found a solution in his official GIT repository.
My operation is to uninstall and reinstall the dnspython module

I'm sending emails using Django version 2.2 and have tested it on the local machine and it works. But the same code throws [Errno 97] Address family not supported by protocol exception.
I also couldn't find any solution online.
I have rechecked my code and there is nothing wrong in it.
I'm using google smtp server with app_password.
Below are Details.
settings.py file
EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_HOST = "smtp.gmail.com"
EMAIL_USE_TLS = True
EMAIL_PORT = 587
EMAIL_HOST_USER = "*******#gmail.com"
EMAIL_HOST_PASSWORD = "app_password"
Email Sending Function
subject = 'Account Password reset mail'
ctx = {
"user" : self.user,
"website" : settings.WEBSITE_NAME,
"site_url" : settings.WEBSITE_URL,
}
msg = render_to_string('login/forgot_password_email.html',ctx)
from_email = settings.WEBSITE_ADMIN_EMAIL
to_email = [self.cleaned_data.get('email'),]
result = send_mail(subject, '', from_email, to_email, fail_silently=False, html_message=msg)
return result
I even try to login to server through SSH and execute through the shell but returns the same error.
>>> from django.core.mail import send_mail
>>> res = send_mail('Subject here', 'Here is the message.', 'example#gmail.com', ['example#gmail.com'], fail_silently=False,)

Thanks in Advance.
I checked Django app in Ubuntu 18.04 without ufw
When added to settings.py these:
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'
Run in the console
python manage.py shell
>>> from django.core.mail import send_mail
>>> send_mail('ddd','fffffffffff', 'myemail#timeweb.ru',['test#gmail.com'],fail_silently=False)
After 7 minutes I get this error.

Where should i check to find the mistake?
I faces the same problem, it was just an unstable internet connection because the problem disappeared as I changed my connection.
I was trying to send an email from my Django app using gmail. I added these email settings to settings.py
EMAIL_HOST = 'smtp.gmail.com'

EMAIL_PORT = 587
EMAIL_USE_TLS = True
But it throws this name resolution error:
