Mail will notify you whenever an email comes in via the new Notification Center in OS X Mountain Lion. While this seems to be a pretty cool feature, it might get a bit overwhelming, especially if you have a lot of mail coming to one of your accounts, or several email addresses, each with their own high volumes of electronic communications.
It’s fairly easy to control the Notifications preferences for Mail, of course, but here’s the thing. Mountain Lion’s Mail app lets you choose one specific mailbox to receive notifications from. This can be a valuable time and attention saver, especially if you marry it to the power of a Smart Mailbox to filter even further.
