Django-SES does not regard DEFAULT_FROM_EMAIL in mail_managers
===

I am using `django-ses` to send e-mail using AWS Simple E-mail Service. I have no problem sending using `send_mail()` but from the same e-mail address set in settings, using `mail_managers()` I am getting a `MessageRejected` exception. 

Here is a walk-through:

    $ python manage.py ses_email_address -l
    Fetching list of verified emails:
    gez@gez.com

And via python shell:

    >>> settings.DEFAULT_FROM_EMAIL
    'gez@gez.com'
    >>> settings.MANAGERS
    (('omat', 'om@tekno.org'),)
    >>> send_mail('test', 'test', 'gez@gez.com', ['om@tekno.org'])
    1
    >>> mail_managers('test', 'test')
    BotoServerError: BotoServerError: 400 Bad Request
    <ErrorResponse xmlns="http://ses.amazonaws.com/doc/2010-12-01/">
      <Error>
        <Type>Sender</Type>
        <Code>MessageRejected</Code>
        <Message>Email address is not verified.</Message>
      </Error>
      <RequestId>66269bb3-ca86-11e1-80db-5b89cf7a6356</RequestId>
    </ErrorResponse>

Thanks for any help.
