Hi Sergey, thank you very much, folder mapping works without any problem now! Edit: I've encounterd another problem related to IMAP mail accounts, though I think it's not the fault of MeMailSettings but by the Fennix Mail Client. When I go to the folder mappings the list of available IMAP folders doesn't seem to update. If I delete and/or add a folder, the mail client doesn't seem to notice this. Is there any workaround to force it to update the IMAP folders? Except of re-creating the account? There is. Just favourite and/or un-favourite a folder and the mail client updates the folders.
