8. Copy the information in "Domain Information". You will need this information to configure Mailgun on your site.

9. If you host your Tendenci site on your own server, you'll want to complete the following in your Tendenci Site.

If your site is hosted by Tendenci, please email "Domain Information" to us and we'll complete the configuration in step 9.

___________________________________________

On your Tendenci site, open the local_settings.py located inside <project_directory>/conf/ . Add these codes to the file.

EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.mailgun.org'
EMAIL_HOST_USER = 'postmaster@DOMAIN'
EMAIL_HOST_PASSWORD = 'PASSWORD'
EMAIL_PORT = 587

Note that you need to replace the proper value of EMAIL_HOST_USER and EMAIL_HOST_PASSOWORD with the domain credentials
you obtained from mailgun website. These are default SMTP login and default password from "Domain Information" respectively. To make sure that everything
is working on the setup you made run a test via shell.

python manage.py shell
>>> from django.core.mail import send_mail
>>> send_mail('MailGun works great!', 'It really really does.', 'tester@YOURHOST.com', ['YOUREMAIL@somehost.com'], fail_silently=False)

The commands above should send an email to YOUREMAIL@somehost.com if everything is set up correctly.
