GUI for a webmail application

[calande]

Hello guys,

I'm working in a small team and we're developing a webmail (http://www.neuridia.org/) application. I'm about to create the GUI and I'd like to do a quick brainstorm here :)

Do you like current webmail GUIs? Could you imagine the webmail interface of your dreams? How would it be?

Ok, I'm going to help you, please have a look at these webmail GUIs:

What do you like in these GUIs, and what don't you like? What about mixing the forum GUI (http://www.phpbb.com/community/) and the webmail GUI? Sort of having a forum interface but to read mails? Forums and webmail have a lot of similarities after all... I'm just thinking at loud here :)

Please let me know your opinion and suggestions
Thanks.
