@amrit i already put those line before this.. but it does not change anything. — MunirohMansoor, Oct 05 '17 at 06:55
It would not. The issue here is for some reason it cannot resolve the address of the remote server. Are you sure its dns is properly configured (and it's not blocked out by some firewall)? — spectras, Oct 05 '17 at 06:58

When I got this error it was caused by the wrong information in the following fields:

EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'my@gmail.com'
EMAIL_HOST_PASSWORD = 'mypassword'
EMAIL_PORT = 587

Except I am not using gmail, however I did find the following information on Django 1.8 sending mail using gmail SMTP

Go to your Google Account settings, find Security -> Account permissions -> Access for less secure apps, enable this option.

Essentially the error "[Errno -2] Name or service not known" can not connect to the email server.
