Django - Gmail - SMTPAuthenticationError

Posted December 10, 2013 45.1k views
I have a Django project, in which I'm attempting to send an email using my gmail account. Note this works fine on my dev machine. Code : from django.core.mail import send_mail ... send_mail(subject, message, settings.EMAIL_HOST_USER, [settings.EMAIL_HOST_USER]) Settings : EMAIL_HOST = '' EMAIL_HOST_USER = '' EMAIL_HOST_PASSWORD = 'xxxxxxxxxxxxx' EMAIL_PORT = 587 # Tried 465 as mentioned in; # EMAIL_USE_TLS = True Anyone know why I'm getting the exception, when running the code in a VPS. Note : running Gunicorn & Nginx Any help or advice appreciated.

Thank You Pablo.
I was having a similar problem and i solve it changing the order of the settings.
It worked exactly like this


You can try it easy with the django shell:

>>> from django.core.mail import send_mail
>>> send_mail('test email', 'hello world', '', [''])

hope it helps
  • I tried everything in the books to get my email to work. Your solution ended up working for me! At first, I had USE_TLS at the bottom. Moving it to the top, like yours, fixed it.

What do the error logs show? Do you have a firewall in place, by chance?
No firewall, currently; just a minimal install to try things out.

It is because Google blocks sign-in attempts from apps which do not use modern security standards (mentioned on their support page). You can however, turn on/off this safety feature by going to the link below:

Go to this link and select Turn On

Moreover google block an ip when you try to send a email since a unusual location, so, you can unblock in the next link
