Help Email Notifications since 4.3 updata

[Pavros13]

Hi All
Just upgraded to 4.3 and having some issues with the stock email client. Since the update after I delete a message it downloads older messages to keep the number of emails to 200 which is what I set in the settings. I know from various posts across the web that people say to set the delete on server option etc but I never had this problem prior to the 4.3 update. Cab any one shed some light on it?

Thanks
