url() removed in django 4

[slavkoja]

I am totally unexperienced with django, but i decided to try your project, as it seems as interested. But initial testing fails with:

...
  File "tmp/reports/reports/urls.py", line 19, in <module>
    from dmarc import urls as dmarc_urls
  File ".venv/dmarc/lib/python3.9/site-packages/dmarc/urls.py", line 10, in <module>
    from django.conf.urls import url
ImportError: cannot import name 'url' from 'django.conf.urls'
    (.venv/dmarc/lib/python3.9/site-packages/django/conf/urls/__init__.py)

Quick search points me to https://stackoverflow.com/a/70319607 where is noted, that url() was deprecated in 3.X and removed in 4.

Your setup.py doesn't limits django to any version in its requires field.
