No sorry. I mainly use web based email and when I don't, I use Microsoft Outlook. My favorite email program is Outlook Express though. It's easy to use and does the job well. Not much more I want from email. I only use the full version because my dsl software set it up for me and I didn't feel like changing lol. I like Firefox too but I couldn't get the menu bar as small as I could with IE. Having a notebook made that an important feature.
Sorry I couldn't offer any alternatives there but I bet the Firefox one is a good one.
