Fix Mail Sleep Popup Bug

[jpu]

Does anybody know how to fix the annoying bug where Mail will open while the Mac is sleeping? For those that aren't familiar, this affects users who leave mail open but hidden (click red button but don't quit). This allows for email to be fetched in the background and for notifications to work.
However, when a Mac is put to sleep, Mail will reappear upon waking the machine. It's an annoying bug, and I don't know how to fix it. Any ideas?

I know this has been happening since Yosemite and there has not been a fix yet. I have reported it to Apple many times but always gets closed due to duplicate report. Just have to deal with it for now, unless someone has figured something else out.
