RuntimeError: OpenSSL 3.0's legacy provider failed to load. This is a fatal error by default, but cryptography supports running without legacy algorithms by setting the environment variable CRYPTOGRAPHY_OPENSSL_NO_LEGACY. If you did not expect this error, you have likely made a mistake with your OpenSSL configuration.

here is the second:

Cron <root@mail> /usr/local/bin/python3 /usr/local/www/iredadmin/tools/delete_mailboxes.py
