First of all, I don't use push or automatic email checking because I find that if I do, my battery is usually dead by the end of the day. I asked Siri to check my email today, and she said I had no new emails. However, when I manually opened the email app, it refreshed and showed me one new email. So I am wondering if Siri actually checks for new emails when you ask her to (as in polling the IMAP server for new unread messages), or if she just looks at the inbox and tells you if there's anything in there unread from what has already been downloaded. If it's the later, it's less useful. I'd like her to actually check for new messages while I am on a long drive for example, so I know if it's worth pulling over to read my email or not. I know it's possible to open the mail app while driving, let it refresh, then ask her, but that seems to defeat the purpose of using Siri.
