kmail is reporting that I have an unread mail in my inbox. There is not. Is there a way to “purge” or even to search for unreads?
Apologies if this is a “google is your friend!” type question but I am in the middle of moving house, and Mrs Wakou would start throwing things at me if I started ploughing through MAN files and KDE’s website…
I would try the ‘compact emails’ option to see if that resolves the problem.
