MacOS Catalina and MacOS Big Sur: Spamsieve deactivates its apple Mail rules

When I activate the rules, Spamsieve deactivates it.

SpamSieve’s plug-in for Apple Mail is not loaded because it is disabled or Mail is not running. When using macOS 10.14, it is normal for the plug-in to be disabled following a macOS or SpamSieve update.

SpamSieve will walk you through the process of adjusting macOS’s settings to enable the plug-in. Once this is done and you’ve relaunched SpamSieve, it will try to re-activate the Mail rules for you.

You can also re-activate the rules manually (once you see SpamSieve’s commands in Mail’s Message menu, so you know the plug-in has loaded) by going to the Rules pane of Mail’s Preferences window and clicking the Active box next to each rule.

It is correct for SpamSieve to disable the rules if the plug-in is not loaded. Do you see the SpamSieve menu commands in Mail’s Message menu? If not, you will need to enable the plug-in.
