Mail Unread Menu is a simple menubar application which can provide you with a quick and easy way to see how many unread email messages are in Apple's Mail. Unlike other menubar notification applications, Mail Unread Menu is actually a plugin for Mail.app, which means that the count is instantaneously updated whenever you recieve new email or change the status of a message.
ALBERTABSTRUS Not only the app doesn't work but it totally prevents Mail from working if you uninstall it without getting rid of the bundle files that comes with it. (Version 3.1.1)
ANONYMOUS Not sure what is going on but this update doesn't appear to work at all. The application is running, mail us running, unread mail is sitting in 2 folders but Mail Unread Menu doesn't tell me there is new mail? Running Tiger 10.4.11 (Version 3.0.1)
