Customizing the Dock unread count in Mail.appEdit
Just found this sweet little tip here.
Mail.app has preferences which allow you to select what mailbox(es) will be used as a source for the unread messages count shown in the Dock icon badge.
- None
- Inbox Only
- All Mailboxes
- or, critically, Any "Smart Mailbox" of your choosing
This means that you can set up a smart mailbox to mirror the contents of any mailbox (or mailboxes) that you care about, and have that show up in the Dock icon.
I use this at work so I can have new messages arriving in my work account immediately brought to my attention, while messages sent to my personal accounts won’t distract me. Prior to learning this tip, I used to actually take my personal accounts offline whenever I got to work, and take them back online before going home.
