No. At that time I haven´t created or imported any filter rules. It was a from 
scratch KMail 2 configuration without any filter rules added. Thus no spam filter 
rules.

So that seems to be a different issue.

Additionally finding: If I let the filter rules only go at incoming mails from 
the POP3 account, lots of mails do not get filtered at all. But so far also no 
cannot move mail errors, thus I keep it that way, select new mails and press 
Ctrl+J on them.
