Mail Rules (some) have stopped working
My 30, or so, Apple Mail rules have worked perfectly for years, but partially stopped working approximately three months ago. (iMac Retina 5K, 27-inch, Late 2014)
Most still work, but a few just stay in the main inbox unprocessed; rather than ending up in their respective Rule mailboxes. I’ve tried to rectify the problem using the following methods which I have read about in this forum; however, no success.
-I have restarted in safe mode multiple time, but no success.
-I have rebuilt those mailboxes multiple times in safe mode, but no success.
-I have reinstalled a fresh copy of macOS Big Sur (11.7.10), but no success
Note; might this have something to do with Mail Preferences; which I am reluctant to mess with without instructions? I’ve noticed that when I delete obsolete rules in Mail App Rule preferences; upon closing and re-opening Mail, or closing Mail, restarting the computer and opening Mail again, the deleted Mail rules reappear, in Mail App Rule preferences. I hope this gives someone a hint of what my problem might be.
