Need Login/SignUp and Webmail-Interface installed from Standard Template on my Postal Mail-Server

I need for my mailserver a webmail interface + automatic sign up/login form for users... Any functional standard template is basically fine with me. At the login page should be just somewhere the logo added (if possible) otherwise there are no specifications or restrictions. Every free responsive basic PSD template or whatever is welcome. The darker the better.
That's all!
