While testing for python-3.9 compatibility, I noticed that some of the tests fail (but the same thing happens with python-3.8):
$ ./test_script
python3
ar
whitelist
per_user
false
no_check
restriction
ptr_whitelist
nomail

A number of tests in the test suite depended on earthlink.com not having an SPF record. They have one now, so I'll need to update the tests with another domain.
