Apple Mail - block incoming mail at certain hours

Question

The question kind of speaks for itself. I want to find a handy way to block new mail from coming in, to avoid distractions.

I was thinking of creating a cronjob that enables and disables firewall rules on my MacBook a few times a day, but maybe there are other ways?

I could also block the traffic on the router, but the idea is that while mail is blocked on the computer, I don't want to block it on mobile devices.

What do you think would be the best solution?

Even better would be if we could send and out of office or other gentile reminder that we only answer mail 2 times a day during 12-13h and 16-17h for example.

But this is not so important, more like an experiment.

Update: I want to find a solution that can be applied company wide. So all desktops cannot receive new email during certain hours.

Just put your machine in do not disturb mode when you want to get some work done: http://osxdaily.com/2012/08/10/turn-off-notification-center-in-os-x-temporarily/
