I am currently running Yosemite 10.10.1 on my MBP Retina, and every time I ask to 'Get New Mail', it does not work. I know this because I will always receive new mail within seconds on my iPhone 5, yet nothing on my MBP. I had somewhat of an issue with this when running Mountain Lion, but the issue seems to be worse now. Any suggestions?
