Mails in my gmx.de "Posteingang" (inbox) shown twice by k9. Number of unread mails is OK. E.g. I currently see number=1, but after opening the corresponding inbox, I see my single new mail twice (I could send screen-shot if needed). With my second web.de account there is no problem!?
Addition: Mails are also send twice from this gmx.de-account.
