--- Comment #3 from k...@trummer.xyz --- Yes, the webmail client (SOGo) shows unread statuses correctly. I already tried akonadictl fsck/vacuum but it didn't help, although the wrong unread count changes. KMail prints this to stdout, maybe a hint? org.kde.pim.messagelist: Circular reference loop detected in the message tree -- You are receiving this mail because: You are the assignee for the bug.
