Dear Aunt TUAW,
I have several Mail accounts. One for work, one personal, and one that gets a lot of junk. I like all of them to come into my Mail app, but I don't need a notification in Mountain Lion every time a piece of junk mail comes through.
Is there a way to only enable notifications for certain accounts?
Your loving nephew,
Sadly, there isn't a way Auntie knows of to do this with OS X Mountain Lion tools, but why not consider using Growl instead? Growl is the spiritual grandfather to Notification Center.
Auntie pinged Uncle Chris from the Growl Project to see what he recommended for you. He pointed Auntie this page, which offers a handy walk through plus an AppleScript that you can customize to your needs.
Auntie asked him about Notification Center integration. He replied that the upcoming Growl 2 will be able to forward custom updates to Notification Center instead of using Growl's display.
Thanks, Uncle Chris! Auntie brainstormed up with a new motto for the Growl project in appreciation: "Growl: Drinking Notification Center's milkshake since OS X 10.8."
