Sending emails using django-SES (Amazon SES)

I've been trying to configure the django-SES services to send outgoing emails and am not sure what is wrong here. Am receving a strange error message,

settings.py

# Email Configuration using Amazon SES Services
EMAIL_BACKEND = 'django_ses.SESBackend'

# These are optional -- if they're set as environment variables they won't
# need to be set here as well
AWS_SES_ACCESS_KEY_ID = 'xxxxxxx'
AWS_SES_SECRET_ACCESS_KEY = 'xxxxxxxxxxxxx'

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

In my design, am inserting all emails into a table and then using celery task to go through all pending emails and firing them.

here is my tasks.py

@task(name='common_lib.send_notification', ignore_result=True)
@transaction.commit_manually
def fire_pending_email():
    try:
        Notification        = get_model('common_lib', 'Notification')
        NotificationEmail   = get_model('common_lib', 'NotificationEmail')

        pending_notifications=Notification.objects.values_list('id', flat=True).filter(status=Notification.STATUS_PENDING)
        for email in NotificationEmail.objects.filter(notification__in=pending_notifications):
            msg = EmailMultiAlternatives(email.subject, email.text_body, '[email protected]', [email.send_to, ])
            if email.html_body:
                msg.attach_alternative(email.html_body, "text/html")
            msg.send()

        transaction.commit()
        return 'Successful'

    except Exception as e:
        transaction.rollback()
        logging.error(str(e))
    finally:
        pass

yet in the celery debug console am seeing the following error

UPDATE

when I changed the setting to 

AWS_SES_REGION_ENDPOINT = 'email.us-east-1.amazonaws.com'

I got a different error, as below

Can you try using this

AWS_SES_REGION_ENDPOINT = 'email.us-east-1.amazonaws.com'

And not the smtp server setting on AWS's dashboard?

(You used AWS_SES_REGION_ENDPOINT = 'email-smtp.us-east-1.amazonaws.com' as mentioned above)

Once you have updated this, you got a new error as updated in your question. This confirms that you now have the correct AWS_SES_REGION_ENDPOINT setting set.

The reason you are getting this new error is most likely because you are confusing the access keys and giving amazon a wrong set of credentials - see detailed comments here - https://github.com/boto/boto/issues/476#issuecomment-7679158

Follow the solution prescribed in the comment and you should be fine, I think.
