After sending a message, sometimes the Unread and Total counts for the outbox folder in the folder list are 1. This is despite there being a notification that the message was sent, and the fact that the message is visible in the sent-mail folder. When clicking on outbox in the folder list, the count immediately clears, and nothing is displayed in the message panes. Reproducible: sometimes. I don't believe this happened before 4.10.
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
I haven't seen the problem recently, not since using 5.0 or later? Marking invalid.
