I finally upgraded to Sierra (had to wait for particular app compatibility), and all my Spamsieve rules for 11 Mail accounts in Drone config have simply disappeared. Other rules that existed before (both enabled and disabled), and a rule I’m sure I created after SS was configured remain in their correct enabled/disabled states.
Is there any easy way to restore SS rules without needing to go through the tedious process of recreating them? I presume trying to restore from Time Machine or clone may affect compatibility issues between ElCap and Sierra.
Will I have to go through it again when (if) I upgrade to High Sierra? Not a pleasant experience.
