Which version of django?

Fixed in 2b2b7d6 . Not released yet.

Django==3.0.2 Does it need to be downgraded in the meantime?

The project is based on the work of volunteers who do not any receive payments for the development of django-mailbox. Instead of going back to previous version Django, I suggests joining to us and taking all necessary steps to preapre a new release (write changelog etc.), which will be a good first step to become a contributor of the project.

@jscpeterson I installed via cloning the git repository instead of using pip which solved the problem you have here.

I can confirm this for 4.8.1 when i install it via pip directly or with git from pip. Installation with pip3 install git+https://github.com/coddingtonbear/django-mailbox.git@c8751f0c9ae85e43f8e775e21dc5ad26adc7f459 it works.

Yes, installing the latest version from git solves the problem for me.

Fixed with the last release (maybe even before)
