Leopard compatible build of GrowlMail Source: The Unofficial Apple Weblog (TUAW)
One of the unfortunate incompatibilities Leopard brought with it was breaking GrowlMail, the plugin for Mail.app that shows new messages via the Growl notification system.

Leopard brought many new features to OS X, but Mail.app may be the biggest sleeper of the bunch. Many Mac users have been skeptical of Notes, to-dos, and RSS feeds being added to Mail, but I have found that it not only makes sense, but makes me much more efficient, too.

Leopard was not all last week brought us tech geeks. Since Gmail was released in 2004, Gmail users have enjoyed the many great things gmail brings, but have savored the idea of free IMAP along with the bundle of joy that is gmail.
