I have my iCloud and my business POP email accounts set up on my iPhone. Both have the same settings for push notifications, and the POP account is set to fetch new data every 15 minutes. When I get an email, I get the alert and banner on the lock screen. But for the past couple of days, I only get notifications for iCloud mail, but no longer for the POP account. I have to open Mail in order for any POP mail to come through on the phone.

I've been reading about similar problems on the Apple support boards, but most posters are referring to their iCloud accounts. And it appears that this is a fairly new wrinkle.

Has anyone else discovered that they're not getting notifications for incoming POP mail?
