It I go into configuration, then POP3 Account Settings, then Advanced, then Destination Folder, the folder list is sorted with all uppercase entries preceding all lowercase entries. That is unlikely to be what a user wants; it certainly isn't what I want. The sort should be case insensitive. If the folder list is long, a user may not realize why a lowercase folder appears to be missing, Reproducible: Always Steps to Reproduce: See details above Actual Results: See details above Expected Results: See details above See details above
This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12, preferably more recent), please open a new one unless it already exists. Thank you for all your input.
