django-ses-backend 0.1.1

A Django email backend for Amazon's Simple Email Service

This is a minified fork of Harry Marr’s django-ses

Management UI and DKIM signing was removed, because:

• AWS can do automatic DKIM signing for you: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/easy-dkim.html,

• It’s backend, so no UI is expected from it.

Another reasons for the fork:

• I need to have it running under Python 3,

• I don’t need all the “additional” feature of django-ses.

Getting going

To get it running, you need to have Django (1.5>=) and Boto (>=2.32.0) installed in your system.

Installing boto:

pip install --upgrade boto

Install django-ses-backend:

pip install django-ses-backend

Add the following to your settings.py:

EMAIL_BACKEND = 'django_ses_backend.SESBackend'

# These are optional -- if they're set as environment variables they won't
# need to be set here as well
AWS_ACCESS_KEY_ID = 'YOUR-ACCESS-KEY-ID'
AWS_SECRET_ACCESS_KEY = 'YOUR-SECRET-ACCESS-KEY'

# Additionally, you can specify an optional region, like so:
AWS_SES_REGION_NAME = 'us-east-1'
AWS_SES_REGION_ENDPOINT = 'email.us-east-1.amazonaws.com'

Alternatively, instead of AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY, you can include the following two settings values. This is useful in situations where you would like to use a separate access key to send emails via SES than you would to upload files via S3:

AWS_SES_ACCESS_KEY_ID = 'YOUR-ACCESS-KEY-ID'
AWS_SES_SECRET_ACCESS_KEY = 'YOUR-SECRET-ACCESS-KEY'

Now, when you use django.core.mail.send_mail, Simple Email Service will send the messages by default.

Since SES imposes a rate limit and will reject emails after the limit has been reached, django-ses will attempt to conform to the rate limit by querying the API for your current limit and then sending no more than that number of messages in a two-second period (which is half of the rate limit, just to be sure to stay clear of the limit). This is controlled by the following setting:

AWS_SES_AUTO_THROTTLE = 0.5 # (default; safety factor applied to rate limit)

To turn off automatic throttling, set this to None.

Django Builtin-in Error Emails

If you’d like Django’s Builtin Email Error Reporting to function properly (actually send working emails), you’ll have to explicitly set the SERVER_EMAIL setting to one of your SES-verified addresses. Otherwise, your error emails will all fail and you’ll be blissfully unaware of a problem.

Note: You will need to sign up for SES and verify any emails you’re going to use in the from_email argument to django.core.mail.send_email(). Boto has a verify_email_address() method: https://github.com/boto/boto/blob/master/boto/ses/connection.py
