pymilter import error on Python 3.6

Scanner crashes on startup with "ImportError: cannot import name 'Milter' from 'pymilter'". System python is 3.6 on Alma 8.10. Tried pip install pymilter==1.0.5 → fails on lightgbm dep.

Resolved by pinning lightgbm<4 for the system py3.6 install. lightgbm 4.x dropped py3.6 support. The UI uses a separate py3.9 venv at /opt/mxguard-ui/venv.
