Today, for example, Kmail got all my new messages right, but it also showed a 
bunch of emails received and read on 9/10/2021 as unread.  This error must be 
before my filtering system kicks in as the 9/10/21 messages were all sent to 
their appropriate folders as unread.

I went to each folder and clicked on the email and, with one exception, kmail 
then showed them as read.  With regard to the one exception, when clicking on 
it Kmail showed the box saying something like it was fetching it.  I have 
learned in that case to quickly close the box or kmail (and the computer 
itself) will eventually freeze.  Nonetheless this email showed as "read" when 
I clicked, while in the appropriate folder "show all emails as read."

For the last year or so I have occasionally apprised this list of this problem 
on the off-chance that it will trigger a response from someone who has had 
this problem before.

Needless to say, I am not hopeful, but any suggestions are welcome.
