Hi, I'm new to mac (and these forums) and I am having some trouble with my Mail App on my new Macbook Pro. Im running mac version 10.8, and in the last few weeks my mail app stopped automatically fetching new messages unless i go into the app and say "get all new mail". I have the settings set to check for mail every 5 minutes and it seems like it stopped getting new mail after i upgraded to mountain lion. Any help?
