Environment variable for blocklist

[MVlaar-GH]

According to the documentation, you can enable blocking. To roll out completely automated it would be nice if there's also a variable for setting which blocklist we actually want to use.

Thanks for the request. Will get that added. It would be best that you add this as an Issue since they are kept track of.
