Non-intuituve behavior: Sending an email with no recipients reports "Success"

[sheepman4267]

As a beginner to this library, I managed to miss this in the docs:

        self.to_emails = [user.email]  # set list of emails to send to

Then, sending the email, I was confused as to why the email didn't go through. I finally looked in the admin and discovered a blank recipients list, while the given EmailNotification object also had its status set to "Success". It would be more intuitive (to me, at least) for this case to raise an exception or at least report a failure in its status field, as sending the message definitely didn't succeed.

I did a little research on the behavior and I'm unsure how to best provide this feedback to the developer. The behavior mirrors how Django send_mail currently works. You can pass an empty recipient_list to the method. I figured out this is to support emails that are intended to be all cc or bcc lists without requiring an single to recipient.

>>> from django.core.mail import send_mail
>>> send_mail("Subject", "body", "from@email.com", [])
0

Do you have any suggestions how to better document this?
