I use GoDaddy email for my work email, and it is a pain having to remember to check every so often to see if I got mail, especially when I only have new mail about 1 in 20 checks.
I have a notifier for my personal gmail account, and that is very handy — saves me a lot of time checking to see what has come in.
GoDaddy only offers a prepackaged notifier for Windows, however (although they supply a Mac executable if you try to download the notifier under Linux).
I checked the FireFox plugins for a generic webmail notifier, but the best one, WebMail Notifier does not have native support for GoDaddy (email.secureserver.net), and I didn’t feel like spending the time writing a custom script, especially since there is forum activity on this exact subject dating back 2 years, with no easily findable script.
Lo and behold? The windows notifier works under WINE. 
Just download the Windows installer (it was wbensetup_PL.msi for me). Then in a terminal run msiexec /i <path_to_file>/wbensetup_PL.msi
Follow the instructions, and, at least in my Gnome toolbar, a notifier appeared.
Nice.
I should note that my current setup is Ubuntu 8.04 with OpenBox as my window manager, running the gnome toolbar.

As an update to this post, I have recently upgraded to Ubuntu 9.04 Jaunty, and this no longer works. It installs, but it is unable to verify my username and password. May have more if I am able to get it to work.

After upgrading to Ubuntu 9.10 Karmic Koala, this solution still does not work, and that’s a disappointment.
