Deep into Power Nap

Hi,

I have disabled Power Nap but I realize that it still is working when on AC. I have a set of rules in Mail.app to keep the mailboxes organized, and I have an iPhone where I only push the Inbox.

Problem is, I don't want Power Nap to update my e-,mail because it also distributes e-mail to the folders on the rules. Sometimes I only pick my macbook later on the day and I need to have all the e-mail I+m receiving on the IMAP inbox.

Does anyone know how to uninstall Power Nap? (macbook retina mid 2012 here)

or better yet

Does anyone know how to go deeper on the Power Nap (maybe by editing preferences files) and select which operations I want Power Nap to do and not to do?

I know I can solve it by closing the Mail.app before I put my computer to sleep, but I actually like to keep it open, I keep all the apps I use on a daily basis open so when I wake it up it's faster to start working.

Kind regards,
