My Login Post page :

        session_start();
        $_Session['Mail']=$un;
        $_Session['Password']=$p;

        header("location: Index.php"); 
        die();

    }

My Index page :

<?php session_start(); echo $_Session['Mail']; ?>

$_SESSION needs to be capitalized, it's case sensitive. $_Session prints because you are declaring a local variable called $_Session. Let me know if it works :)
