Dear all,
I'm using Django 1.11 and want to send mails by utilizing an Exchange 2013
server which only supports NTLM for SMTP authentification. I realized that
the default email backend `django.core.mail.backends.smtp.EmailBackend`
only supports LOGIN, PLAIN or CRAM-MD5 for authentication. Luckily, I found
another promising backend
(https://github.com/shadiakiki1986/django-smtp-ntlm-backend) for SMTP with
NTLM authentication. Installation of the backend was successful but it does
not work.
The following happens at the Python console:
>>> from django.core.mail import send_mail
>>> send_mail('test subject', 'message', '[email protected]',
['[email protected]'], fail_silently=False,)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/usr/local/lib/python2.7/site-packages/django/core/mail/__init__.py", line
62, in send_mail
return mail.send()
File
"/usr/local/lib/python2.7/site-packages/django/core/mail/message.py", line
348, in send
return self.get_connection(fail_silently).send_messages([self])
File
"/usr/local/lib/python2.7/site-packages/django/core/mail/backends/smtp.py",
line 111, in send_messages
sent = self._send(message)
File
"/usr/local/lib/python2.7/site-packages/django/core/mail/backends/smtp.py",
line 127, in _send
self.connection.sendmail(from_email, recipients,
message.as_bytes(linesep='\r\n'))
File "smtplib.py", line 736, in sendmail
self.rset()
File "smtplib.py", line 470, in rset
return self.docmd("rset")
File "smtplib.py", line 395, in docmd
return self.getreply()
File "smtplib.py", line 369, in getreply
raise SMTPServerDisconnected("Connection unexpectedly closed")
smtplib.SMTPServerDisconnected: Connection unexpectedly closed
Relevant settings in settings.py:
EMAIL_ENABLE=True
EMAIL_BACKEND=django_smtp_ntlm_backendNTLMEmail
EMAIL_HOST=<mailserver>
EMAIL_PORT=25
EMAIL_HOST_USER=<domain>\<user>
EMAIL_HOST_PASSWORD=<password>
DEFAULT_FROM_EMAIL=<email>
EMAIL_USE_SSL=False
EMAIL_USE_TLS=False
The settings for the mail server are correct and the mail server is working
fine. I am able to send mails with a SMTP testing tool called Swaks with
the same settings using the same mail server. Does anybody has experience
with using Exchange and NTLM authentication for sending emails with Django
1.11? Maybe there is another email backend I can use? I can imagine that
things might be easier with a newer Django version and Python 3 because of
changes in the underlying smtplib, but I'm stuck to Django 1.11. I'm
grateful for any hints.
Best regards
Fabian
