Whenever i boot my system, akonadi floods my screen with messages about "mailbox doesn't exist", messages fly by so fast and are so numerous that's all i can say about it. My guess is that it's having some problem connecting to IMAP server. This flooding error messages has been an issue for years now, and it made me actually stop using kmail because it's extremely annoying. Reproducible: Always
haven't seen this problem for quite a while anymore
