I put my MBP to sleep last night by closing the lid. Mail app was open at the time. I wake up this morning and have 3 emails on my iPhone (same email accounts on my MBP). I decide to read the emails on my MBP and check out the new notification center. To my surprise, the emails were not there. My preferences are set to check email every minute. I decided to wait and see what happened. After about 15 to 20 minutes, the emails finally appear on the MBP. Under Lion, these emails would have been available immediately upon opening the MBP up. Anyone else having this issue, or know why it is taking so long for mail to wake up and start retrieving?
