--- Comment #24 from naworsk...@gmail.com --- I can confirm this bug since my distribution upgrade. The to me latest known working version is kmail 4.14.7 with akonadi 1.13.0. Like with Thunderbird, syncing the affected imap account parallel with the old/working kmail/akonadi version makes the ghost/shadowed/grayed ("undead") mails disappear forever. Maybe its trivial to say, that the undead mails appear also if moving them somewhere, not only by deleting them. This is really annoying if you use Filters to move incoming mails around, because these undead mails are returning tagged as unread. Speaking about tags: When the bug started to affect me, I was able to make the undead mails appear as "normal" in by changing the status from unread to read. So I could delete them (again), but after refreshing it just reappeared with an additional undead mail. Changing the Status is now (kmail 5.0.3, akonadi 5.0.51) not possible anymore. -- You are receiving this mail because: You are watching all bug changes.
