Django registration SMTPServerDisconnected error - django

Question

I use django-registration for my project to manage user registration, login, etc. But When I sign up for an account I came across this problem:
SMTPServerDisconnected
For the record, I did configure email related settings in my settings.py:
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 465
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'myemail#gmail.com'
EMAIL_HOST_PASSWORD = 'mypassword'
Also I have all the templates needed and accessible. So this problem doesn't have anything to do with that.
More Error description:
After I click on the send activation email, it takes a long time before it finally give that error.
Here is the traceback (not complete):
SMTPServerDisconnected at /accounts/register/
Connection unexpectedly closed
last trace back:
/usr/lib/python2.7/smtplib.py in getreply
line = self.file.readline()
except socket.error as e:
self.close()
raise SMTPServerDisconnected("Connection unexpectedly closed: "
+ str(e))
if line == '':
self.close()
raise SMTPServerDisconnected("Connection unexpectedly closed")
...
if self.debuglevel > 0:
print>>stderr, 'reply:', repr(line)
resp.append(line[4:].strip())
code = line[:3]
# Check that the error code is syntactically correct.
# Don't attempt to read a continuation line if it is broken.
Thanks for any suggestion.

Answer 1

I think at least one setting is incorrect. Port 587 is required for TLS [1]
EMAIL_PORT = 587

Answer 2

Finally I figured this out. I post my solution here in case someone else get stuck here. The problem is the Gmail port. Use 587 and it worked.
I saw it here: https://code.djangoproject.com/ticket/9575
I wonder why some people can use 465 and some can't. It cost me a few hours to find out. Hope your guys won't!
EDIT: See here for more dicussion about use of port.
To use port 465, you need to call smtplib.SMTP_SSL(). Currently, it looks like Django only uses smtplib.SMTP().
Seems 587 is the right choice.

Answer 4

Django Gmail Confi # settings.py
EMAIL_BACKEND ='django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_USE_SSL = True # use port 465
EMAIL_USE_TLS = False # use port 587
EMAIL_PORT = 465 # OR 587
EMAIL_HOST_USER = os.environ.get('USER_EMAIL')
EMAIL_HOST_PASSWORD =os.environ.get('USER_EMAIL_PASS')
helper.py (function)
from django.core.mail import send_mail
def send(sub=None,message=None,recipient=[]):
# def send_mail(
# subject,
# message,
# from_email,
# recipient_list,
# fail_silently=False,
# auth_user=None,
# auth_password=None,
# connection=None,
# html_message=None):
send_mail(subject='contact mail'
,message='Test Mail'
,from_email=EMAIL_HOST_USER
,recipient_list=['mail_list']
,fail_silently=False)
return True

If you are not having any luck with the above answers, you may want to check to see if you have set your DEFAULT_FROM_EMAIL in the settings.py
# project/settings.py
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 465
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'myemail#gmail.com'
EMAIL_HOST_PASSWORD = 'mypassword'
DEFAULT_FROM_EMAIL = 'myemail#gmail.com'
