Description Philippe ROUBACH 2021-02-11 14:49:01 UTC 
Experiment 1

1. when a mail arrives then immediately display its contents and put it in trash
2. in any folder try to display any mail contents

Result :

you get a message saying please be patient kmail is retrieving the mail

For every restart of kontact then you get a crash.
You need to restart akonadi  with "akonadictl restart" to avoid a crash

Experiment 2
1. when a mail arrives wait for the filtering process is finished
2. display the mail contents

Result :

No problem



Conclusion :

I suggest kmail does not display a mail before finishing the filtering process.

Comment 1 Philippe ROUBACH 2021-05-15 09:49:01 UTC 
another problem:

if a mail is displayed before filtering then it is a dangerous mail because it is not virus checked and spam checked.
