Error sending email from django app

I’ve started a new production droplet in NYC2, it has virt-io, and backup.

I have a django application with many other services running, like redis, node, sockjs and celery.

Also, i want to point ou that my local server runs the exact same configuration with regards to email, and everything works fine. I did not change anything regarding to firewall or networking in my droplet.

Can anybody help me fix this error?

My problem is that i can’t send email from my django app.

My configuration is :

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587 #also tried with 465
EMAIL_HOST_USER = 'xxxxxxxxxx@gmail.com'
EMAIL_HOST_PASSWORD = 'MyPassWOrd'

Here is the error:

File "<console>", line 1, in <module>
