Settings for delays between emails, batches and the size of batches.

[jorenham]

For sending out large amounts of emails, it is generally a good idea to send them out in batches. This way your email servers aren't flooded and can recover in between batches.

Hey @jorenham,

Thanks for an awesome contrib. Code looks good, though I think it is important to stress that also sub-second delays can be used. Sending 10k emails with 1 second delay is not really feasable. ;)

It would be great, though to also have coverage here. Basically, you mock out time.sleep. In any case, fix the syntax errors! ;)

Very well done, thanks!

LGTM except for one issue: settings in tests need to be overridden in a different way. See for example here: https://github.com/dokterbob/django-newsletter/blob/9d4b93ac875f91fcb9c4938fb3ffccd5b85dea8a/tests/test_web.py#L646

Or look at the Django docs on this topic here https://docs.djangoproject.com/en/1.8/topics/testing/tools/#overriding-settings.

Lastly, you've used Python 3's built-in mock, which is unavailable on 2.7. You need to add the mock library as a test requirement. https://pypi.python.org/pypi/mock

I see unittest.mock breaks in python 2.7. Should I use Mock instead?

[dokterbob]

Yep.
