horde vs squirrel mail, general public "hotmail style" domain email services sign up

I notice in my cpanel that i have the option of squirrel mail and horde as far as my default web based email client. i am thinking of starting a very low key public web based and pop/smtp offered services but with a "signup process" do either one of these come with sign up process for public access ?

thanks
