Why Rule under Mail Preferences does not stay on?
I follow some of the Discussions here. In Mail (11.1) under Preferences, I have made a Rule so that the follow-up emails of the Discussions are directly received in a particular mailbox. Strangely for the last few days, all such emails go directly to Junk. I haven't changed anything in the Rule. What was the error, I wonder!
