No unread message number in the dock in Lion

First make sure that Mail > Preferences > General tab > Dock unread count: > is not set to None.

If that isn't the issue, sometimes it can be fixed by dragging the mail icon off the dock (pufff), then dragging a new one on from the applications folder.

I believe that option is gone with Lion.

Now if I can get it to bounce when new mail comes in...

Pretty sure they took bounce outta the interface this time, but just wait, I'm sure someone like DockStar will add it back in at a later date 🙂
