Launch And Hide Mail reduces desktop clutter by making your Mail app invisible.
Since Mac OS X 10.4 Tiger, Apple Mail ignores the "Hide" checkbox when installed as a login item.

Unfortunately, this problem has still not been fixed in Mac OS X 10.5 Leopard. Launch And Hide Mail, as the name suggest, is a tiny application that will launch Apple Mail and hide it immediately after launch.
