Deleted Mails Reappear
Hello,
using an iPad2 with a pop3 account I noticed that deleted mails from the trash folder reappear again in the trash folder and sometimes even in the inbox folder. Deleting the mails several times doesn't help. Why can't I delete the mails definitely? Are my mails in an apple server stored after downloading them from my provider? I didn't register for an apple cloud account because my privacy is very important and I do not thrust the cloud.
Furthermore, I fail trying to post this issue with the ipad2, because I coun't read the caracters, so I'm using now a windows notebook.
iPad 2, iOS 9.3.3
