Django SMTP settings
<p>Maybe I wasn't clear enough about the problem, so I will try once more.
I need to use SMTP server to send large amount of emails with Django application. 
Settings that I used to establish connection are:</p>

<pre><code>EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.premium-web-domain.com'
EMAIL_HOST_USER = 'username@premium-web-domain.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_PORT = 25
</code></pre>

<p>And I get error like this:
smtplib.SMTPAuthenticationError: (535, '5.7.8 Error: authentication failed:')</p>

<p>Any ideas what might be the problem?</p>
