IMAP - Duplicates of folders Drafts, Trash, Sent

Hi everybody, I’m glad to be here,

in my IMAP-Account were created Duplicates of the Special-Folders (Drafts, Trash, Sent) by the Mail-App. How can I use to my original folders and make unvisible/deactivate the new folders? In the backend, it seems not possible. Perhaps by changing the php code?

Best Regards

I think it’s better to check the bug tracker directly. There are already some folder-related reports and you might add your problem:
