Django error : smtplib.SMTPDataError

Question

>>> from django.core.mail import send_mail>>> send_mail("allo", 'here is the message', 'my_email@gmail.com', ['my_email@gmail.com'], fail_silently=False)
Traceback (most recent call last):

smtplib.SMTPDataError: (421, b'4.3.0 collect: Cannot write ./dfv4IKaDvq007500 (bfcommit, uid=0, gid=133): No such file or directory')

I did export DJANGO_SETTINGS_MODULE=email_name.settings in bash where email_name is the name of my django app. Because as you could see I am working with interactive python.

I am trying to send an email, and I obtain this error. How could I fix this issue?

Thanks!

P.S. If the question is unclear, please let me know.

Notice that I am not looking for to create a django project, but rather test out the method send_mail(). That's why the code settings.py is standard.

Answer 1

I believe in your settings.py you are going to need to add some email configuration, like this

EMAIL_FROM = 'youremail@gmail.com'
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'something@gmail.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_USE_TLS = True

Then you could create a view that calls the send_mail function. Something like this

def send_an_email(request):
    from django.core.mail import send_mail
    send_mail('Subject here', 'Here is the message.', 'from@example.com', [to@example.com'], fail_silently=False,)
    return render(request, '/email_sent.html')

Reference

Of course you'll need a url to call this view. So in your urls.py (I assume you have this already) have something like this

url(r'^send_my_mail/', 'Project_name.views.mail.send_an_email', name='mail')

And then visit the url to see if the email got sent properly.
